This study examines Christian death rites in modem Korea in the light of the complex interplay of Confucian and Christian values. It is based on the fact that Korea, once the most thoroughly Confucianized state in East Asia, has become one of the most dynamic Christian countries in the world within the space of a century. The study uncovers the ways in which Korean Christians, in their death rites, have struggled to balance 'religious piety to God' and 'filial duty to ancestors', which represent core Christian and Confucian values respectively. They cannot simply choose the one at the expense of the other as both are integral to their identity. This study innovatively classifies death rites into three categories: ritual before death (bible-copying), ritual at death (funerary rites), and ritual after death (ancestral ritual). After presenting historical and contemporary data of the three death rites, the study provides two different types of analysis: one is a historical-theological analysis and the other sociological-anthropological. Drawing upon historical and theological perspectives, it reveals the underlying principle of complex phenomena surrounding the three death rites. The thesis then explores these death rites in terms of three sociological and anthropological theoretical themes, viz. embodiment, exchange, and material culture. The three death rites are viewed as a 'total social phenomenon', a concept derived from Marcel Mauss' study and employed here as an overarching interpretive framework.

The purpose of this study was to investigate the relationships between lexical and grammatical knowledge in the L2 acquisition of English by Korean EFL learners by examining how the depth of lexical knowledge that Korean learners have about English verbs is related to their grammatical knowledge. For this study, L2 research into depth of lexical knowledge and generative syntactic theory have been reviewed to suggest the interdependent nature of vocabulary and grammar in L2 acquisition (Nation, 1990, 2001; Chomsky, 1981, 1986, 1995; Herschensohn, 2000). Data were collected from Korean EFL learners through a depth of vocabulary knowledge test which focused on semantic, morphological, and syntactic properties of English verbs and a grammar test. The results showed that there was a high positive correlation between vocabulary and grammar knowledge in L2 English acquisition by Korean learners, and that semantic, morphological, and syntactic properties of lexical knowledge all contributed to the prediction of L2 learners' grammatical knowledge. In particular, the syntactic property of lexical knowledge was found to be the most important predictor of grammatical knowledge. However, it was also found that the morphological property was not as important in the prediction of L2 grammatical knowledge as the syntactic property. Based on these findings, it was argued that the in-depth view of L2 lexical knowledge might be appropriate for explaining the interdependent nature of lexical and grammatical knowledge, since this in-depth perspective sees lexical knowledge as consisting of various properties such as semantic, morphological, and syntactic features. On the other hand, a generative view on syntax also seems to provide an account of how each property of lexical knowledge would be related to overall grammatical knowledge. Thus, the syntactic property of word knowledge such as argument structures and subcategorization frames might serve as a connector which links lexical and grammatical knowledge. Finally, some possible accounts of why the morphological property of vocabulary knowledge did not contribute as much to the prediction of L2 grammatical knowledge as the syntactic property were provided on the basis of the notion of argument structures, the characteristics of morphological knowledge assessed by the in-depth vocabulary test, and L2 lexical development model proposed by Jiang (2000).

Strain-specific resistance conditioned by a single dominant gene in soybean cv. York inoculated with SMV-G1, revealed no symptoms and no detectable viral replication (R). Unlike the hypersensitive response (HR), the R response did not result in localized virus and induction of a series of defense responses, but in inhibition of virus replication. However, this resistance was overcome by the resistance- breaking strain, SMV-G4, which induced lethal necrosis (N). Unlike HR, G4 strain was not restricted but spread ina restricted pattern along the vein, stem and into upper un-inoculated leaves where it induced necrosis. Like HR, PR proteins were found to accumulate in the N response and were named SPR (soybean pathogenesis-related) proteins. On the basis of major similarities in molecular weight characteristics and enzyme-substrate specificities, SPRs are proposed to be classed into four groups: SPR1; 1a, 1b, 1c, 1d; SPR2: 2a, 2b, 2c; SPR3: 3a, 3a’, 3b, 3c, 3d, 3e; SPR4. The functions of SPR1 and SPR4 groups have not yet been determined. The SPR2 group was identified as β-1,3-glucanases (GLN) and classed two subgroups. The SPR3 group was identified as chitinases (CHN) and classed three distinct subgroups. Like HR, the N response induced a series of defense responses with marked temporal increases, in a bimodal pattern, of phenylalanine ammonia-lyase (PAL) and peroxidase (POX) activities, bimodal pattern of PAL mRNA and chalcone synthase (CHS) mRNA induction, a single pattern of chitinase mRNA induction, and glyceollin and lignin accumulation. These marked increases occurred at or just before the time of initial appearance of necrotic lesions, or following necrosis development for localization of virus. Total RNA isolated from soybean inoculated with SMV-G4 were used for synthesis of cDNA by reverse transcription, and amplified using 3-hydroxy-3-methyl-glutaryl coenzyme A reductase (HMGR)-specific primer sets by polymerase chain reaction. Amplified cDNAs were cloned into Bluescript vector (pKS⁻), transformed into E. coli, isolated pSOY HMGR and used as a probe for Northern analysis. We demonstrate that expression of HMGR mRNA is correlated with strain-specific resistance (R). SMV coat protein (CP) degraded in vitro by proteolysis during purification. The CP of SMV purified from infected leaves had an major size of 34 kD in SDS-PAGE with minor peptides of 32 and 31 kD. The minor peptides increased during the storage at 4°C or with trypsin treatment, and reacted with antiserum to intact virions. This heterogeneity of protein was not removed by alkaline phosphatase treatment for varying time intervals, and was not related with phosphorylation and dephosphorylation, or with virus maturation. These studies provided additional evidence of N- or C-terminal exposure on the particle’s surface.

The present study was undertaken to: (1) develop a reliable method of measuring eggshell quality, (2) determine whether diet alterations that cause a somewhat reduced rate of egg production could influence shell quality, and (3) determine whether certain biochemical parameters involved in calcium metabolism are related to shell quality.

Both MDMV-A and -B were transmitted by natural infection and mechanical inoculation on South Dakota adapted sorghum hybrids and occurred at the Brookings area. Grain sorghum hybrids were found to react differently to mechanical inoculation with MDMV-A and -B, respectively. Strain A usually induced a systemic mosaic symptom, while strain B usually produced local and necrotic symptoms. However, a few cultivars infected with strain B exhibited systemic symptoms. During a comparative ultrastructural study of MDMV infection, there was an obvious difference in inclusion bodies between MDMV-A and MDMV-B. Electron microscope revealed the presence of pinwheels, bundles, tubes, scrolls, and laminated aggregates in cells of sorghum leaf tissue systemically infected with MDMV-B, while no laminated aggregates were found in cells of sorghum leaf tissue infected with MDMV-A. Ultrastructural aspects of HOK sorghum plants in the primary acute stage of symptom development and MDMV-A interaction, exhibited obvious ultrastructural changes in host cell morphology such as cell wall abnormalities. The cell wall abnormalities involved cell wall thickenings and protrusions associated with paramural bodies, extended plasmodesmata, and extra protoplasmic sacs. The objectives of this study are to determine the response of South Dakota adapted sorghum cultivars to mechanical inoculation, to identify potential reservoirs for MDMV, to compare sorghum cultivars reaction to MDMV-A and -B, and to describe the symptom development at different stages of sorghum cultivars inoculated with MDMV. Also, to observe the cytological modification of HOK sorghum cultivar inoculated with MDMV-A mechanically, and finally to compare the difference of inclusion bodies between strain A and B.
