The Vietnamese government has proposed contract farming through a new type of cooperative as an institutional innovation which aims to restructure the agricultural sector. However, policy changes often impact farmers, who bear the primary effects of the transition process. Understanding households' strategies for land use and livelihood is crucial for policymaking in the agricultural development field. This study was conducted in the rural Binh Dao commune in Central Vietnam. We analyzed household members' labor force changes and their livelihood behaviors after their participation in a contract farming scheme using qualitative analysis methods combined with geographic information system (GIS) support, based on secondary data and in-depth interviews of 190 farmers. Simultaneously, we created a digital map of the cooperative's production area to investigate changes in land use and production activities. The findings show that contract farming shaped the vertical coordination of the value chain from the farmers to the cooperative and agricultural product trading companies. Subsequently, it encouraged land use and labor efficiency due to mechanical support. In addition, it also increased productivity and protected farmers from market risks. However, despite its positive effects on agricultural productivity in this case, the contract farming scheme could not achieve the restructuring of the rural labor force toward non-agricultural sectors. Ironically, farmers in the Binh Dao commune tended to increase cultivable land during the agricultural restructuring program, rather than switching their labor forces to non-agricultural sectors. The lack of stable non-farming job opportunities in rural Vietnam results in challenges to the efficiency of agricultural restructuring programs. Consequently, farmers in the Binh Dao commune are still smallholder farmers, depending on the family labor force.

This paper analyzed romance novels imported into Korea in the 1980s and examined the traits of Korean girls' culture at that time. To this end, This paper chose as subjects the series of 'high-teen romance' published by Samjungdang, 'princess bestseller' by Seoul Publishing and the 'silhouette romance' by Joongang Ilbo in the 1980s. Through the aspects of the paperback romances, the traits of the artist, the content of the work, and the response of the reader, this paper analyzed the position and affection of romance as a genre in Korean culture in the 1980s. In the 1980s, most of the paperback romances available in Korea were translations of the modern and progressive present lines of Harlequin Enterprise's category romance. There were also many writers who were mostly introduced with progressive characters like Charlotte Lamb. The Harlequin romance depicts a story of sensual love. These translated 1980s paperback romance novels allowed girls in Korea to freely imagine the problems of sex and love. In particular, it showed a new perspective on women's sexuality. In Korean love novels, the sexuality of women was treated as an object for the gaze of men. The novels of female writers as college student who criticized this dealt with women's sexuality, but focused on criticism and resistance to the ideology of chastity. The paperback romance made it possible for women to freely enjoy their sexuality by escaping the ethical standards of reality. In addition, the paperback romance was an escape from the frustration of love. Romantic love in Korean love novels did not lead to the unification of mind and body, and always ended in tragedy. On the contrary, the paperback romance started with the fear of the girl who felt love for the first time, showed the process of winning over anxiety, confirming love and reaching a happy marriage. Through this, girls understood general love that was not subordinated to the ideology of chastity, and accepted love positively. The process of establishing romance as a genre in Korean culture and the traits of its readers have not yet been sufficiently clarified yet. This paper compared the romance genre with the other love novels of the day, explaining the position and meaning of the romance genre in Korean culture in the 1980s. Through this, we were able to chart the historical development of the Korean romance genre.

The purposes of this study was to develop a valid scale measuring organization-related anxiety and to use this scale to examine the relation of organizational anxiety to demographic variables, job satisfaction and organizational committment. A series of studies were conducted to develop a scale for organizational anxiety. Initially, the 97 items were adopted by expert ratings. A exploratory factor analysis with a sample of 435 workers yielded a preliminary version of organizational anxiety scale with 28 items. Subsequently, a confirmatory factor analysis was conducted with a sample of 566 workers, leaving 20 items. The final version of the organizational anxiety scale consisted of 4 sub-factors: perception of future uncertainty, perception of locus of control, interpersonal anxiety, and perception of alternatives. In this study, the examined demographic characteristics included sex, age, type of occupation, type of industry, occupational position, monthly income and educational level. Organizational effectiveness was composed of job satisfaction and organizational commitment. As mediators, organizational culture, life satisfaction, self efficacy, and social support were explored. The negative relationship was observed between organizational anxiety and organizational effectiveness. The results showed the significant differences in organizational anxiety by demographic characteristics. The mediators were explored for the relationship between organizational anxiety and job satisfaction and between organizational anxiety and organizational commitment. The negative relationship between organizational anxiety and job satisfaction was mediated by the group culture, the developmental culture, the rational culture, life satisfaction, self-efficacy, and social support. Individuals with the higher level of these mediators reported greater job satisfaction even if they experienced organizational anxiety. The partial mediation effect of the group culture, the developmental culture, the rational culture, life satisfaction, and social support was observed on the negative relationship between organizational anxiety and organizational commitment. These results implies that job satisfaction and organizational commitment can be improved with the interventions on organizational cultures, self-efficacy, and social support despite the presence of organizational anxiety. Based on these results, the implication and limitations of this study and the directions for future research discussed.

Due to the development of digital technology, studies regarding smart wear integrating daily life have rapidly increased. However, consumer research about perception and attitude toward smart clothing hardly could find. The purpose of this study was to identify innovative characteristics and perceived risk of smart clothing and to analyze the influences of theses factors on product attitudes and intention to adopt. Specifically, five hypotheses were established. H1: Perceived attributes of smart clothing except for complexity would have positive relations to product attitude or purchase intention, while complexity would be opposite. H2: Product attitude would have positive relation to purchase intention. H3: Product attitude would have a mediating effect between perceived attributes and purchase intention. H4: Perceived risks of smart clothing would have negative relations to perceived attributes except for complexity, and positive relations to complexity. H5: Product attitude would have a mediating effect between perceived risks and purchase intention. A self-administered questionnaire was developed based on previous studies. After pretest, the data were collected during September, 2006, from university students in Korea who were relatively sensitive to innovative products. A total of 300 final useful questionnaire were analyzed by SPSS 13.0 program. About 60.3% were male with the mean age of 21.3 years old. About 59.3% reported that they were aware of smart clothing, but only 9 respondents purchased it. The mean of attitudes toward smart clothing and purchase intention was 2.96 (SD=.56) and 2.63 (SD=.65) respectively. Factor analysis using principal components with varimax rotation was conducted to identify perceived attribute and perceived risk dimensions. Perceived attributes of smart wear were categorized into relative advantage (including compatibility), observability (including triability), and complexity. Perceived risks were identified into physical/performance risk, social psychological risk, time loss risk, and economic risk. Regression analysis was conducted to test five hypotheses. Relative advantage and observability were significant predictors of product attitude (adj $R^2$=.223) and purchase intention (adj $R^2$=.221). Complexity showed negative influence on product attitude. Product attitude presented significant relation to purchase intention (adj $R^2$=.692) and partial mediating effect between perceived attributes and purchase intention (adj $R^2$=.698). Therefore hypothesis one to three were accepted. In order to test hypothesis four, four dimensions of perceived risk and demographic variables (age, gender, monthly household income, awareness of smart clothing, and purchase experience) were entered as independent variables in the regression models. Social psychological risk, economic risk, and gender (female) were significant to predict relative advantage (adj $R^2$=.276). When perceived observability was a dependent variable, social psychological risk, time loss risk, physical/performance risk, and age (younger) were significant in order (adj $R^2$=.144). However, physical/performance risk was positively related to observability. The more Koreans seemed to be observable of smart clothing, the more increased the probability of physical harm or performance problems received. Complexity was predicted by product awareness, social psychological risk, economic risk, and purchase experience in order (adj $R^2$=.114). Product awareness was negatively related to complexity, meaning high level of product awareness would reduce complexity of smart clothing. However, purchase experience presented positive relation with complexity. It appears that consumers can perceive high level of complexity when they are actually consuming smart clothing in real life. Risk variables were positively related with complexity. That is, in order to decrease complexity, it is also necessary to consider minimizing anxiety factors about social psychological wound or loss of money. Thus, hypothesis 4 was partially accepted. Finally, in testing hypothesis 5, social psychological risk and economic risk were significant predictors for product attitude (adj $R^2$=.122) and purchase intention (adj $R^2$=.099) respectively. When attitude variable was included with risk variables as independent variables in the regression model to predict purchase intention, only attitude variable was significant (adj $R^2$=.691). Thus attitude variable presented full mediating effect between perceived risks and purchase intention, and hypothesis 5 was accepted. Findings would provide guidelines for fashion and electronic businesses who aim to create and strengthen positive attitude toward smart clothing. Marketers need to consider not only functional feature of smart clothing, but also practical and aesthetic attributes, since appropriateness for social norm or self image would reduce uncertainty of psychological or social risk, which increase relative advantage of smart clothing. Actually social psychological risk was significantly associated to relative advantage. Economic risk is negatively associated with product attitudes as well as purchase intention, suggesting that smart-wear developers have to reflect on price ranges of potential adopters. It will be effective to utilize the findings associated with complexity when marketers in US plan communication strategy.

Hazard Analysis is one of the basic tasks to ensure the safety of chemical plants. However, it is an arduous, tedious, time-consuming work and requires multidisciplinary knowledge and demands considerable cognitive load from the analysts. To overcome these problems, there have been attempts to automate this work by utilizing computer technology, particularly in the area of knowledge-based technique. There is two methods in the risk assessment of Chemical plant; quantitative and qualitative risk assessment. Both of them have been applied respectively, but if the integrated method of quantitative and qualitative risk assessments is used, all of the advantage of two methods can be applied. It is difficult to carry out integrated risk management of chemical plant. Therefore, automated integration system of risk management is necessary. We developed S/W Automated System for Hazard Screening & Analysis(ASCA) and applied to practical plant. By applying ASCA to case study, we can get the information about relative ranks of equipments, variable deviation, and consequence of potential accident. In this study, we applied ASCA to the H.T.U(Hydrotreating Unit) of the process to produce aromatic material. We could know relative ranks of equipments, variable deviation of malfunction in storage tank, D-101, and consequence of potential accident using ASCA. If integrated risk management in the chemical plant is applied, we can develop the emergency plan and prevent the accident.

Innovative pharmaceutical company certification support policies have been implemented since 2012. This study was conducted to identify the perceptions of stakeholders and related experts on the formation process and policy satisfaction of this policy, and to identify factors that explain policy satisfaction. The survey was conducted by e-mail and facsimile of the pharmaceutical companies, universities, and government - affiliated research institutes. The effective response rate was 38.4% (61/159). As a result of the cross-sectional survey, the perception of policy necessity was the most positive among the policy formation process, and all the other stages and perception of policy satisfaction were at the medium level. As a result of examining the influential factors related to the variables of the respondents' personal variables and the policy formation process, it is confirmed that the factors that have the greatest influence on the policy satisfaction are the perception of the performance of the certified company. Also, perceptions of appropriateness and follow - up ability were similar in magnitude of impact on policy satisfaction. This study can be used as a basic data to systematically and effectively improve the certification and support policies of innovative pharmaceutical companies based on the consumer's perception. However, due to limitations such as being carried out at the beginning of policy implementation, verification and supplementation are necessary through further research.

This study was conducted to examine the effects of a supplemented Chungkukjang diet on oxidative stress and antioxidant nutrients in Streptozotocin (STZ, 45 mg/kg of BW, IP injection)-induced diabetic rats. Diets that contained soybean Chungkukjang powder (SC), Yakkong Chungkukjang powder (YC), and Yakkong Chungkukjang powder with black food added (YCB) were administered to the STZ-induced diabetic rats for seven weeks. The increased lipid peroxide contents of their serum and liver were slightly controlled by providing them three types of Chungkukjang. The retinol level in the serum was 7.5 times higher in the STZ-induced diabetic group after the provision of YC. The total antioxidant capacity (TAC) level in the serum was higher in the STZ-induced diabetic group after the provision of YCB. Also, the retinol and tocopherol levels in the liver of the STZ-induced diabetic rats increased after they were provided YCB, and the decreased reduced glutathione (GSH) /oxidized glutathione (GSSG) level in their liver improved after they were fed a diet that contained YC. Moreover, the decreased anthocyanin level in the liver of the STZ-induced diabetic group improved after the provision of three types of Chungkukjang powder. These findings suggest that the Chungkukjang diet is a valuable food for the management of the health of diabetic patients and for the prevention of diabetic complications.

Orthodontic mini-implants, despite its usefulness as anchorage, have some limits such as loosening. Therefore, various shapes and lengths have been studied. The aim of this study is to analyze the shape and length of mini-implants mechanically. The shapes of mini-implants (1.6 mm, Dual Top, Jeil Medical Co., Seoul, Korea) were cylindrical and taper. The lengths of mini-implants were 6 mm and 8 mm. The tested groups were 5 groups (cylindrical 6 mm, cylindrical 8 mm, taper 6 mm, taper 8 mm and taper 8 mm modified whose thread is reduced from the middle to upper part). All were inserted and removed on the polyurethane foam with the torque measured. During insertion and removal, the taper shape needed higher torque than the cylindrical shape, and the 8 mm length than the 6 mm length (p<0.001). The taper 6mm group showed superior insertion torque (p<0.001) and similar removal torque to the cylindrical 8 mm group. The taper 8 mm modified group with gradually reduced threads, showed continuous high removal torque after the peak. The initial mechanical stability can be provided by the tapered shape and also, affected by length and thread design.

This study aims to investigate how flipped learning-based socioscientific issue instruction (FL-SSI instruction) affected middle school students' key competencies and character development. Traditional classrooms are constrained in terms of time and resources for exploring the issues and making decision on SSI. To address these concerns, we designed and implemented an SSI instruction adopting flipped learning. Seventy-three 8th graders participated in an SSI program on four topics for over 12 class periods. Two questionnaires were used as a main data source to measure students' key competencies and character development before and after the SSI instruction. In addition, student responses and shared experience from focus group interviews after the instruction were collected and analyzed. The results indicate that the students significantly improved their key competencies and experienced character development after the SSI instruction. The students presented statistically significant improvement in the key competencies (i.e., collaboration, information and technology, critical thinking and problem-solving, and communication skills) and in two out of three factors in character and values as global citizens (social and moral compassion, and socio-scientific accountability). Interview data supports the quantitative results indicating that SSI instruction with a flipped learning strategy provided students in-depth and rich learning opportunities. The students responded that watching web-based videos prior to class enabled them to deeply understand the issue and actively engage in discussion and debate once class began. Furthermore, the resulting gains in available class time deriving from a flipped learning approach allowed the students to examine the issue from diverse perspectives.

This paper is to investigate how cognitive bias of college students and entrepreneurs relates to perceived risks and entrepreneurial opportunities that represent uncertainty, and how various cognitive bias and entrepreneurial efficacy In the same way. The purpose of this study is to find improvement points of entrepreneurship education for college students and to suggest problems and improvement possibilities in the decision making process of current entrepreneurs. This empirical study is a necessary to improve the decision-making of individuals who want to start a business at the time when various attempts are made to activate the start-up business and increase the sustainability of the existing SME management. And understanding of the difference in opportunity evaluation, and suggests that it is necessary to provide good opportunities together with the upbringing of entrepreneurs. In order to achieve the purpose of the study, questionnaires were conducted for college students and entrepreneurs. A total of 363 questionnaire data were obtained and demonstrated through structural equation modeling. This study confirms that there is some relationship between perceived risk and cognitive bias. Overconfidence and control illusions among cognitive bias have a significant relationship between perceived risk and wealth. Especially, it is confirmed that control illusion of college students has a significant relationship with perceived risk. Second, cognitive bias demonstrated some significant relationship with opportunity evaluation. Although we did not find evidence that excess self-confidence is related to opportunity evaluation, we have verified that control illusions and current status bias are related to opportunity evaluation. Control illusions were significant in both college students and entrepreneurs. Third, perceived risk has a negative relationship with opportunity evaluation. All students, regardless of whether they are college students or entrepreneurs, judge opportunities positively if they perceive low risk. Fourth, it can be seen from the college students 'group that entrepreneurial efficacy has a moderating effect between perceived risk and opportunity evaluation, but no significant results were found in the entrepreneurs' group. Fifth, the college students and entrepreneurs have different cognitive bias, and they have proved that there is a different relationship between entrepreneurial opportunity evaluation and perceived risk. On the whole, there are various cognitive biases that are caused by time pressure or stress on college students and entrepreneurs who have to make judgments in uncertain opportunities, and in this respect, they can improve their judgment in the future. At the same time, university students can have a positive view of new opportunities based on high entrepreneurial efficacy, but if they fully understand the intrinsic risks of entrepreneurship through entrepreneurial education and fully understand the cognitive bias present in direct entrepreneurial experience, You will get a better opportunity assessment. This study has limitations in that it is based on the fact that university students and entrepreneurs are integrated, and that the survey respondents are selected by the limited random sampling method. It is necessary to conduct more systematic research based on more faithful data in the absence of the accumulation of entrepreneurial research data. Second, the translation tools used in the previous studies were translated and the meaning of the measurement tools might not be conveyed due to language differences. Therefore, it is necessary to construct a more precise scale for the accuracy of the study. Finally, complementary research should be done to identify what competitive opportunities are and what opportunities are appropriate for entrepreneurs.
