As the aging population increases, the need for new product development (NPD) for elderly-friendly food packaging is also increasing. Through the use of consumer research, this study derived the following problems when elderly people use food packaging: “The contents easily overflow when holding the container”, “It is hard to pour”, “Remnant remains after pouring”, and “It is hard to use a straw”. To address these problems, this study applied the following principles of TRIZ: principle 1 (segmentation) and principle 22 (blessing in disguise). In order to materialize the improvement plan, this study developed an elderly-friendly pouch-based packaging from the perspective of universal design. This study shows that it is possible to use the TRIZ technique in the NPD of food packaging, and that it is possible to secure commercial competitiveness from the view of universal design. This study is expected to serve as a starting point for further study on the NPD of elderly-friendly food packaging.

Since small and medium enterprises (SMEs) play an important role in economic development, the government implements various supports. Nevertheless, SMEs have difficulties in gaining a competitive advantage in the market owing to lack of capital and capacity. Accordingly, SMEs try to secure a competitive advantage through innovation. Government support is necessary for the innovation of SMEs, and it is essential for food SMEs as well. Whether government support for firms can affect firm’s innovation is still a matter of debate. In particular, it is necessary to empirically investigate the relationship between government support and innovation for SMEs in latecomers to the food industry such as Korea. Therefore, this study conducted an empirical study on the factors that determine the innovation performance of food SMEs by government support. This study used a two-stage regression model. The government support does not unilaterally affect innovation performance, but rather, an endogeneity problem occurs through the interaction between them. This study examined the interrelationships between variables for a clear estimate of government support. Before two-stage regression, this study used the ordered logistic regression to determine the instrumental variables. Each instrumental variable was estimated for the seven types of government support that are normally implemented. The result suggests that the government certification support is effective in improving the innovation performance of food SMEs. This study is useful to establish innovation strategies for supporting food SMEs’ innovation in late-coming countries.

This study examines the influence of government support, research and development (R&amp, D) investment and cooperation networks on sustainable innovation performance of the medium-sized food firms in South Korea. Climate change, population growth, lifestyle change and consumer demands for new products allow firms to explore innovation for sustainable growth. In the food industry, where various stakeholders are involved in the value chain, government support, R&amp, D investment and cooperation are affecting firms&rsquo, sustainable performance. However, there are few empirical studies that examine the relationship among them, especially regarding medium-sized food firms. This study aimed to analyze data regarding Korean food firms through a structural equation model. To overcome data scarcity, this study collected new data for 67 medium-sized food firms. The data is matched with the firms&rsquo, 10-year data on management, innovation performance, and cooperation networks. This study can contribute to filling the literature gap by exploring what innovation strategies should be used to improve food SMEs&rsquo, innovation performance in the latecomer countries, which have developed their food industries relatively recently.

In order to improve the health status of adolescents, studies are needed to illuminate the essence of their general and dietary lifestyle. Thus, we conducted this study to verify meaningful relationships between adolescent usage of social media (USM), which plays an important role in their life, their food consumption behavior (FCB), and their dietary satisfaction. This study used two analysis methods: t-tests and structural equation modeling (SEM). This study verified whether there was a significant difference in adolescent FCB depending on their USM using t-tests. This study proposes that the following FCBs showed significant differences between users and non-users of social media in adolescents: a tendency to try new types of food (t = 2.134, p < 0.05), a tendency to avoid foods with harmful risks such as suspected spoilage (t = 3.513, p < 0.001), a tendency to eat bread or fruit for a simple breakfast (t = −3.893, p < 0.001), and a tendency to often use home meal replacements (HMR), eat out or have food delivered (t = −3.245, p < 0.01). Furthermore, this study used SEM to verify the causal relationship between adolescent USM and their dietary satisfaction. According to the results of SEM, adolescents’ USM mediated by the FCB of preferring convenience fully mediates the negative relationship between adolescent USM and their dietary satisfaction (p < 0.01). It is necessary to reverse the situation in which adolescent dietary satisfaction decreases as their FCB of preferring convenience increases. Government regulations for food companies and autonomous efforts for quality improvements on their part are needed.

This study aims to explore whether a firm&rsquo, s financial sustainability is enhanced by open innovation especially after a global financial crisis. There are few studies on the relationship between open innovation and financial sustainability. This study aimed to fill the literature gap by analyzing the change in the financial ratio according to the increase or decrease in open innovation. We used a case study method regarding large Korean food firms. Korea is a latecomer in the food industry, which is driven by large companies. This study is meaningful for financial sustainability studies of countries with a lack of resources and small market size, which require open innovation. The findings of this study are as follows: The most preferred alliance strategy of large food firms is joint research. In order to secure raw materials and markets, open innovation was actively conducted abroad, which increased growth and profitability. However, a firm which rarely adopts open innovation could grow steadily through internal strategies. On the other hand, although relatively many open innovations have been used, growth and profitability could decrease. Firms with sufficient absorptive capacity strengthen financial sustainability through open innovation.

Background Exercise is recommended for the management of chronic low back pain (CLBP). Trialists have proposed numerous mechanisms to explain why exercise improves pain and function in people with CLBP, but these are yet to be synthesised. Objective To synthesise the proposed mechanisms of benefit for exercise in people with CLBP. Design Review. Methods The Physiotherapy Evidence Database (PEDro) was searched from inception to July 2019. Randomised controlled trials of adults with CLBP, indexed in PEDro as ‘fitness training’, were included. Two reviewers independently screened and extracted data from each study. Data were analysed quantitatively and qualitatively using thematic analysis. Results 186 studies were identified and 110 were included in the analysis. Thirty-six studies (33%) did not provide a mechanism of benefit for exercise in people with CLBP. Of the remaining studies, most provided more than one mechanism, from which 33 unique mechanisms were identified. These were grouped into five themes which, from most to least common, were: neuromuscular (n = 105 (44%)); psychosocial (n = 87 (36%)); neurophysiological (n = 22 (9%)); cardiometabolic (n = 15 (6%)); and tissue healing (n = 12 (5%)). The effects of these proposed mechanisms on outcomes for people with CLBP were seldom examined. Conclusions This review identified a variety of mechanisms proposed in clinical trials to explain why ‘fitness training’ works for people with CLBP, but these mechanisms were seldom tested. Randomised controlled trials investigating the mediating effects of these mechanisms may be warranted to better understand why exercise works for CLBP.
