This study was conducted to investigate the effects of medicinal plants with additives on storage characteristics of sausage. The water activity of the sausage with the additives tended to decrease with the storage time: the highest value was shown in the Angelica added sausage samples, in both cases added with dried powder as well as with extracted powder. The Paeonia extract powder added sausage had the lowest pH value. The herbal plant added sausages showed the lowest cooking and storage losses among all. The values of TBA (thiobarbituric acid value) and VBN (volatile basic nitrogen) increased with storage time, but the values of the sample with the extract powder additive were lower than those of the freeze-dry powder additive. Total plate counts of bacteria increased with storage time fur all samples, but those for the samples with Pueraria, Platycodon, Angelica, Bupleurum and Paeonia additives exhibited lower values than the control. From the above results, the sausages with medicinal plant additives showed the superior storage safety and quality characteristics.

Noodles were manufactured using chickpea powder to evaluate quality characteristics. Compared to noodles made of wheat flour, noodles made with chickpea powder showed higher contents of protein, lipids, ash, and dietary fiber. Among noodle cooking characteristics, weight, moisture absorption rates, volume, and turbidity decreased significantly as the added amount of chickpea powder increased. Comparisons made of the color of noodles with raw noodles after cooking showed that the brightness (L value) of raw noodles tended to decrease as more chickpea powder was added after cooking, and levels of red (a value) and levels of yellow (b value) tended to increase as more chickpea powder was added after cooking. The texture of noodles with added chickpea powder tended to increase as more chickpea powder was added, such as hardness, springiness, gumminess, cohesiveness, and chewiness.

Smart city, which employs information and communication technology (ICT) to resolve urban problems, is gaining more research attention in the innovation research. However, most previous studies regard citizens as merely passive accepters of the smart city services, focusing on individual private values. The present study aims to expand existing limited perspectives by applying public value management theory. Drawing from the literature review, we developed a dual perspective that a smart city service should encompass: private and public value. Then we set up a causal relationship between the value recognitions and intention to adopt smart city services. We further related antecedent variables to the dual value recognition in terms of citizens' characteristics: prior knowledge, personal innovativeness, and citizenship. Two case subjects among currently operating smart city services in South Korea were selected to empirically investigate our hypothesis. Results confirm the recognition of both public and private value is significantly related to the citizens' personal characteristics and resultant attitude towards acceptance and support for diffusion of the smart city services. This study is expected to provide useful implications for a new angle for the recipient of the smart city services, value orientation of the services, citizen's participation, and method selection for promotion.

Purpose - Prior studies have found that the characteristics of managers, corporate governance structure, corporate social responsibility and so on affect firm value. This study explores whether managerial overconfidence affects firm value through empirical analysis. Design/methodology/approach - Korean-listed non-financial companies from 2011 - 2017 are collected as the research sample. Firm value is measured by Tobin's Q, and managerial overconfidence is measured using a composite index encompassing various financial data. OLS and fixed effect model are used to investigate the relationship between managerial overconfidence and firm value. Findings - Managerial overconfidence is positively associated with firm value. Additional analysis reveals the following: (1) In the three subsamples of large, backbone, and small- and medium-sized enterprises, managerial overconfidence is beneficial to firm values. (2) Managerial overconfidence increases firm value on the t+1 year. Research implications or Originality - We use a comprehensive index with higher trust and feasibility to measure manager overconfidence and empirically confirm that managerial overconfidence can become a factor to improve firm value. Thus, it is necessary for shareholders to adopt an objective and neutral attitude and reasonably understand the psychological characteristics of managers when selecting CEOs. In addition, it is necessary to continue to optimize the measurement method of managerial overconfidence.

This study is to compare cultural characteristics and the clothing value between Korean and American college women. Also this study is to analyze the culture effect on the clothing value. The cultural characteristics is explained by Hofstede's five Cultural Dimensions- power distance, individualism, masculinity, uncertainty avoidance and long-term orientation. 800 questionnaires, were utilized for this study. The SPSS 12.0 was used to analyze the technical statistics like average and frequency, 1-test, $x^2$, factor analysis and multiple regression analysis. Also the LISREL 8.0 was used to Perform a confirmatory factor analysis. The result showed, first, there were 5 major cultural differences between Korean and American college women. Comparatively, Korean college women showed higher uncertainty avoidance and long-term orientation, and lower power distance, individualism and masculinity. Second, there were differences in the clothing value aspect. Korean college women considered the aesthetic clothing value to be most important, however, American college women considered the economic clothing value to be most important. Third, there were some differences in the clothing value because of the cultural differences. For Korean college women, there were 5 major cultural differences that had an effect on the aesthetic, social, religious and economic clothing values, however, for America college women, the 5 major cultural differences had an effect on the aesthetic, social, and religious values but no effect on the economic value.

When we looked at the seasonal food dregs of the eastern side of gangwondo, gangneung city's summer and winter food dregs showed 25.9 and 25.8% respectively due to the presence of beach areas and ski resorts. Sokcho city showed 28.12% in summer and yangyang gun's summer food dregs showed 40.2%. Yangyang gun's august food dregs showed 2.7 times larger than annual average amount. Outlook density showed regional characteristics. Data showed that food dregs' amount rate has been reduced gradually from 2005 because of the prohibition of direct filling up. As a result of compositions analysis, the eastern side of gangwondo's water fraction of living dregs were lower than that of chuncheon city where is located at the gangwondo's inland area. chuncheon city's data showed residential areas 53.5%, community areas 56.8% and commercial areas 55.6%. These discrepancies caused by the characteristics of dregs discharge type and climate. The caloric value of dregs has been increased incrementally after the ban of food dregs' direct filling up. Therefore, heating value of the dregs exceeds the existing furnace design spec and it can cause high caloric value problems, so we need additional research to solve these problems.
