Professional development (PD) plays a crucial role in promoting teachers' linguistic competence and teaching quality, contributing to enhancing and maintaining sources of effective teachers, especially novice teachers with little teaching experience. Mentoring has emerged as a PD activity in which a novice teacher is mentored and directly supported in various aspects by an experienced professional. It has been popularly adopted in several countries in the world, including Vietnam. This study was conducted to investigate the extent of various types of support that the mentoring program provided. Additionally, it aimed at exploring the level of satisfaction of EFL novice teachers regarding the types of support in the program. The study was designed as a mixed-method study, using a questionnaire and interviews as data collection instruments. The study involved the participation of twenty-two EFL novice teachers who have less than three-year experience in teaching and took part in a mentoring program held by a private English center in the Mekong Delta. The finding showed that all types of support in the program, including instructional support, emotional support, physical support, and institutional support were provided to a high extent. The participants hold a high level of satisfaction with these types of support. Based on the findings, some recommendations were suggested to promote the quality of the program and meet participants' needs and expectations. [For the full proceedings, see ED654100.]

The purpose of this study is to investigate the potential impact and effectiveness of mobile learning in the context of a flipped classroom and also address implications for future curriculum design. The researchers developed a mathematics curriculum featuring the use of mobile devices in the context of a flipped classroom. Thirty pre-service secondary teachers participated in the study. They completed a pre-study survey, student reflections about the usefulness of mobile learning, and a post-study survey of their views on their use of mobile devices and their TACI classification scores. Results show there was a statistically significant difference in students' TACI scores between the pre-survey and post-survey. Mobile devices were mainly used for task performance in individual learning and group discussion in cooperative learning. Students' potential and self-confidence were improved through connection, communication and collaboration activities using mobile devices. For better pedagogical scaffoldings in classroom environments, four necessary conditions were suggested in this paper: approachable convenience (access route to a website), the convenience of using mobile devices (free data environment), promotion of real-time interaction between students (instantaneous messaging), and connection between communicating and sharing activities from group discussion to whole class discussion.

A technology-friendly teacher education program can make pre-service teachers more comfortable with using technology from laggard to innovator and change their learning styles in which they prefer the use of technology in teaching. It is investigated how a technology-friendly mathematics education program, which provided 49 pre-service teachers an opportunity to conduct technology-based class activities and to develop teaching materials using technology, affects their perceptions about technology and learning styles. Results showed that participants were more highly receptive to be an innovator or early adopter which means they are more eager for using technology as a teaching tool. This implies that teachers' perceptions and learning styles can be potential, sustainable, and possible variables to be changed for meaningful teaching with technology.

The school superintendent for Duval County (Florida) describes his experiences in developing a school-based management organizational structure. The following elements are involved: (1) funds are allocated to schools based on needs of children in schools, (2) specific educational objectives for a school are set by people associated with the school, (3) decisions on how funds for instruction are to be spent are made in the school, (4) organization of instruction is determined at the school level, and (5) parents participate in school decision-making. The superintendent made a commitment to the school board and administration that principals would be "front line decision-makers" in the system. This commitment required a reassessment of each principal to determine competence, enthusiasm, commitment to system goals, and flexibility to change. (Author/MLF)

Marked by a history of political opposition and fluctuations of control that have occurred in the name of national development and modernization, the Korean press (consisting of 34 newspapers) today produces a somewhat typical eight-page newspaper that is a mixture of Korean and Chinese characters. As most of the newspapers are clustered in the capital city of Seoul, so are the major institutions of higher learning. Although an estimated 250 students receive journalism degrees annually, Korean journalism departments face the following problems: a lack of teaching materials and textbooks; a lack of understanding by media practitioners regarding the importance of professional journalism education; a lack of coordination between the journalism departments and media agencies, particularly in the area of hiring students to work for newspapers; a shortage of experienced teaching staff and necessary instructional facilities; and the failure of journalism graduates to pass the tests for employment administered by various newspaper companies and radio-television agencies.

The coefficient of thermal contraction/expansion (CTE) of aggregates may influence mixture CTE and low temperature performance since aggregates account for about 85% of mixture volume. However, due to difficulties in measuring the CTE of aggregate and mixtures, there have not been many studies on the effect of aggregates on mixture low temperature performance. The existing CTE predictive equation and models are based on the ratio of the bulk volume and CTE of aggregates and binder ignoring the potential disproportionate contribution of coarse and fine aggregates due to their spatial arrangement. The purpose of this study was to investigate the thermal contraction characteristics of coarse and fine aggregates and their effects on the low temperature performance of asphalt pavements. Two limestone aggregates with a high and a low CTE were selected for this study. Dense graded asphalt mixtures were prepared with these two aggregates and cross-blends of the aggregates for which the coarse fraction of low and high CTE aggregates were blended with the fine fraction of high and low CTE aggregates. The CTE and cracking temperature of the mixtures were determined using the Ohio CTE Device (OCD) and the Asphalt Concrete Cracking Device (ACCD), respectively. The coarse aggregates had a significantly greater influence on mixture CTE and low temperature performance as compared to the fine aggregates. The average measured CTE difference between low and high CTE aggregate mixtures was found to be lower than the difference obtained from CTE predictive equation. Measured mixture CTEs also exhibited Glass Transition behavior. [ABSTRACT FROM AUTHOR]

Container ship designs have evolved very quickly to keep up with the demands of the market to achieve maximum profitability by delivering maximum cargo at minimum cost. Therefore, we need to consider all aspects to confirm the proposed design is structurally safe and meets LR Rules requirements and recommendations which are based on our accumulated experience in the container ship segment. LR Rules have been developed over many years to provide design guidelines for this rapidly evolving market. However, we know that many options for container ship design arrangements developed by the engineers require consideration beyond the prescriptive Rule requirements and additional analyses are required to ensure their structural adequacy. This paper describes the additional design considerations for Ultra Large Container Ships (ULCS) which come from LR design appraisal experience and investigation of structural incident cases and associated FE analyses. As a result, recommended design features for specific structural details and arrangements are discussed in this paper. [ABSTRACT FROM AUTHOR]

This paper presents a numerical and experimental study of sloshing loads on liquefied natural gas (LNG) vessels. Conventional LNG carriers with membrane-type cargo systems have filling restrictions from 10% to 70% of tank height. The main reason for such restrictions is high sloshing loads around these filling depths. However, intermediate filling depths cannot be avoided for most LNG vessels except the LNG carrier. This study attempted to design a membranetype LNG tank with a modified lower-chamfer shape that allows all filling operations. First, numerical sloshing analysis was carried out to find an efficient height of the lower-chamfer that can reduce sloshing pressure at partially filled conditions. The numerical sloshing analysis program SHI-SLOSH was used for numerical simulation; this program is based on SOLA-VOF. The effectiveness of the newly designed tanks was validated by 1:50-scale three-dimensional tank tests. A total of two different tanks were tested: a conventional tank and modified tank. As test conditions, various filling depths and wave periods were considered, and the same test conditions were applied to the two tanks. During the tests, slosh-induced dynamic pressures were measured around the corners of the tank wall. The measured pressure data were post-processed and the pressures of the two different tanks were statistically compared in several ways. Experimental results show that the modified tank was quite effective in reducing sloshing loads at low filling conditions. This study demonstrated the possibility of all filling operations for LNG cargo containment systems. [ABSTRACT FROM AUTHOR]

In this study, a scries of tests was conducted for variously scaled model tanks. The models used in this study were membrane type tanks based on the design of a 138K liquefied natural gas (LNG) carrier, and had scale ratios of 1:70, 1:50, 1:40, and 1:30. The tests were carried out under simulation of various irregular sea conditions. The objective of the study was to investigate peak pressures of sloshing impact measured at the tank corner. In the four different tanks, pressure measuring points in the tanks were the same when those are scaled up to the real size. The measured pressure data was post-processed using a statistical approach, and the test results were compared across tanks of different scales. [ABSTRACT FROM AUTHOR]

An effective design method to control the transitional behavior of welding distortion at the cofferdam bulkhead (BHD) occurring in the erection stage and sea trial test has been established using FEA and measured data. Variation of distortion at the cofferdam BHD was measured according to the progress of the manufacturing process. The distributions of 2nd load causing the 2nd distortion were identified with a non-linear FEA. The distribution of initial welding distortion and residual stress were assumed to be initial imperfections, which were identified with simplified thermo-elastic method. Based on the results, the proper quality control standard with the shapes of initial welding distortion was proposed in order to prevent the excessive 2nd distortion which causes damage in the insulation system installed in cargo tank of LNG carriers.

The purpose of this study is to identify the design sloshing load and evaluate the structural safety of the sprayed polyurethane foam (PUF) with density of 45 kg/m3, which is applied as an insulation material of full containment onshore LNG storage tank, under the seismic leakage condition. To do this, first, the design sloshing load was evaluated as per relevant design codes and the fluid structure interaction (FSI) simulations under the seismic load corresponding to the safety shutdown earthquake-aftershock (SSEaft) after the inner tank leakage. From the result, the design drop height corresponding to the design sloshing load was determined through a series of preliminary wet drop tests. And then, the sloshing safety assessment of PUF was carried out using the wet drop test and simulation under the defined design drop height. Here, the wet drop simulations were performed using the established PUF material model by static and dynamic material tests and FSI simulation technique. Based on the results of the extensive wet drop tests and simulations with the design sloshing pressure, it was verified that the PUF sprayed inside the outer tank in the LNG storage tank considered has a sufficient structural safety under the design sloshing load caused by the LNG leakage and seismic load of SSEaftershock.

The instrumented indentation test is widely used for nondestructive evaluation of the mechanical properties of materials. In particular, the uniaxial tensile curve can be estimated through this technique using a spherical indenter with static condition setup. First, to determine the representative stress and strain, the indentation parameters were verified depending on the indentation speed conditions; this was done for the dynamic flow curve estimation using the instrumented indentation test. Multiple load-depth curves were analyzed to determine the maximum load, stiffness, and strain-hardening exponent; the most dominant parameter was verified depending on the indentation speed using the representation model.

This paper reports an ISPH(Incompressible Smoothed Particle Hydrodynamics) method that estimates water splash, slamming pressures and forces caused by water impact between a body and a calm water surface in time domain. This method has great advantage when dealing with highly non-linear flow problems because it stems from Lagrangian description of fluid flows. In real, the advantage is more pronounced for extremely transient flows such as slamming of arbitrarily shaped bodies occurs in very short time duration because no mesh system is necessary in this particle. In the present study, employing an assumption that a rigid body falls freely into the water surface, several quantities such as time varying impact pressures, water splash rising up along the wedge side, etc. are numerically simulated considering the time varying entry velocity after contact by decrease of body inertia. Numerical calculations are carried out for 2 types of wedge models including straight wedges with certain slopes and wedge with a tilting angle. The simulated results for local peak pressures and pressure distributions with time are compared with experimental measurements. [ABSTRACT FROM AUTHOR]

This paper covers the numerical investigation of slamming problem with 2-D wedge and ship section. Both of them are assumed as a rigid body and dropped into calm water with free falling. Because of the nonlinear behavior of water-entry wedge associated with violent freesurface motion including jet-like splash and water fragment, there are some difficulties in prediction numerically with conventional gridbased approach. In this study, a modified MPS (Moving Particle Semi-Implicit) method which is a particle-based approach and solves the continuity and Navier-Stokes equations for incompressible and viscous fluid has been used for representing time-varying entry velocity of rigid body, local pressure and vertical force on the body and the pressure distribution on the wet surface. The validation of the present simulation results are performed through the comparison with the experiments conducted in KRISO, Korea. [ABSTRACT FROM AUTHOR]

This paper examines the increasing establishment of cancer centers by Korean hospitals since 1980 through the perspective of neo-institutional organization theory. Specifically, this paper uses the theory of organizational isomorphism, however, the usage of the theory in this paper differs somewhat from that of other implementations in that status was included as a variable that mediates the mechanism of mimetic isomorphism. For the analysis, the discrete timelogit model, which is one of the statistical methods used for Event History Analysis, was used. As a result, this paper shows that mimetic isomorphism of establishing cancer centers was observed only in high status hospitals. Furthermore, policy on the establishment of National Cancer Center and increase in cancer related knowledge in the form of the number of articles related to cancer had an effect on the establishment of cancer centers. This indicates that general hospitals were building cancer centers because of the pressure of normative isomorphism. For future research, the societal repercussions of establishing many cancer centers should be examined. [ABSTRACT FROM AUTHOR]

In contemporary society, cancer is not just a pathological disease but a complex entity which interrelates with individuals, families, society, and knowledge. In this paper, I focused on how knowledge on cancer is structured in Korea from 1990 to 2013 by using scientometric and network analysis. Three types of networks (affiliation network, keyword network, affiliation-keyword network) were analyzed. At first, affiliation network showed how institutions in Korea collaborate with each other. Universities are the main institutions that led cancer research in Korea. They also led the collaboration with foreign institutions. Hence the number of international collaborations increased since 2007 especially with European institutions. Secondly, keyword network showed that gastric cancer and breast cancer are the main two subjects in Korean cancer research. Apoptosis is another important keyword that is connected with many other keywords. However, since mid 2000s, cancer research diversified. Many types of cancer were researched nowadays. Lastly affiliation-keyword network showed how affiliations and keywords are interrelated to each other. It can be inferred from the network that the central affiliations in the network researched all the main keywords and their positions in the heterogeneous network did not change as time goes on.

This paper seeks to advance Michel Callon's performativity theory in the sociology of markets by applying the theory to a case of market change. Drawing on ethnographic data on the transformation of the street food market in San Francisco, CA from 2008 to 20010, I argue that performativity theory can be improved by more fully incorporating the distinction.first highlighted in this context in Judith Butler's (2010) critique.between illocution and perlocution. Callon's performativity theory in economic sociology shows that economic theories are not mere descriptions of naturally arising phenomena by revealing the work that necessarily goes into assembling markets (and the agencies that inhabit them). In particular, Callon's theory highlights how theories themselves, through the intervention of market devices, come to reshape the markets they purport to describe such that they become accurate descriptions. However, performativity theory has been criticized for overemphasizing the stability of markets while leaving market change undertheorized (Overdevest 2011). Starting from the exchange between Butler and Callon (2010) in the Journal for Cultural Economy, I extend the linguistic concepts of illocution and perlocution by analogy to illocutionary and perlocutionary use of material devices .devices that are either deployed as intended in the right "total situation" or used 'gspeculatively" to produce uncertain effects. I argue that the devices deployed in the transformation of the street food market in San Francisco can be understood as an example of this second type, thus opening the way for a fuller theorization of market change from within performativity theory.

One concern addressed in the literature on intergenerational relations is the extent to which the support provided by middle-generation adults (G2) to their elderly parents (Gl) is compatible with support provision to young adult offspring (G3). A "competition" or "conflict" often is assumed between the two forms of support, though evidence from Western nations fails to consistently confirm this. Moreover, this issue has received little study in non-Western societies, especially in East Asia where populations are aging rapidly. Using the 2006 East Asian Social Survey data sets, we test the competition hypothesis regarding the association between middle-generation adults5 support to aged parents and adult offspring in South Korea and Japan. More generally, we examine frequency of support offered to Gl and G3 family members in these countries to assess family support provisions in the context of rapid population aging, Eastern cultural values, and distinct policy contexts. We find that support provided to G3 family members is not predictive of reduced support to Gl members, in either country. Instead, when middle-generation adults provide support, they tend to do so for both generations. Additionally, we find more frequent provisions of support to G3 than Gl family members, across family lineages. How these results compare with Western findings is discussed, along with consideration of shifting social and cultural situations in East Asia. [ABSTRACT FROM AUTHOR]

This paper explores the cross-national variations of individuals' idea about just income among OECD countries showing increase of inequality. A primary assumption of the study is that the several structural factors of each society affect the difference between objective inequality and subjective evaluation for its inequality in the eyes of observers. More specifically, the main object of the study is to examine indexes with which to assess the trend of fairness judgments of income among OECD countries showing increase of actual inequality. Additionally, it is also intended to explore possible factors for explaining these variations or common features identified by the indexes. To answer these questions, the paper relies on data set of 1999 and 2009 ISSP. Especially, we focus on the OECD countries that show the discrepancy between objective inequality and subjective evaluation for its inequality. They are France, Korea, Sweden and U.S. that show increasing fairness judgments of income although actual inequality has been aggravated. In this paper, we contend the effect of the neo-liberalism, increasing unemployment rate and diffusion of individualistic responsibility for this ironic phenomenon. [ABSTRACT FROM AUTHOR]

Although many firms implement various kinds of human resource practices, a substantial number fail to get what they desire. Organizational practices are frequently decoupled from intended outcomes. This study examines these inconsistencies by applying the concepts of means-ends decoupling, referring to a gap between practices and outcomes, and intra-organizational dynamics. In addition to providing insights into the development of networkability within firms, this paper is one of the first to yield empirical support for the successful networks argument by demonstrating that networkability are key factors that serve not only to attenuate means-ends decoupling but also to improve organizational performance.
