This study examined whether there is difference in consumers' product attitude according to the type of buying behavior values and the type of price discount among their lifestyle. First, the factors of values comprising consumers' buying behavior were derived as frugal buying, impulse buying, quality buying, and principle buying. Cluster analysis showed that the types of buying behavior value included high quality impulse buying, reasonable buying and practical buying. Second, it was found that there were differences in product attitude according to the type of consumers' buying behavior values. Third, interaction effect was found between the type of price discount and consumers' product attitude according to the type of buying behavior values. Fourth, among the factors of value comprising consumers' buying behavior, frugal buying factor has an effect on the product attitude with price discount of 50% and quality buying and impulse buying factors have an effect on the product attitude with bundle price discount (1+1). The above mentioned result of study suggests that when a company establishes a strategy of price discount, it should consider sales promotion strategy taking account of consumers' buying behavior values and type of product price discount.

In 2030s, as we enter in to the era of BT (Bio-Technology) market opening up, technologies in all areas such as IT, data analysis, IC and biochemistry are necessitated. New development in technology will be based on "Convergence", especially between IT and BT. In order to have synergy effects from the convergence, those related industries and universities should be physically inter-related in an appropriate location. Until 2009, 819 industrial clusters where many Korean industries and firms are concentrated have been constructed in Korea. They have had supports from various institutions and facilities. However, few systems designed to assist "intellectual property (IP) service" for technology convergence are found in Korea. Thus, by analyzing current problems and challenges of the Korean industrial clusters, this paper suggests a possible answer to maximize the synergy from technology convergence through organic cooperation among companies in industrial clusters. This paper finds that the Korean industrial clusters need to establish IP service supporting center while suggesting its function and concept on organization structure, and work flow, which help firms to develop IP strategies. In addition, the paper provides a direction for current IP system and policies implemented by the Korean government to be more effective to small-and-medium-sized companies located in the industrial clusters.

Objectives: The purpose of this study was to assess input for health promoting schools (HPS), and to evaluate HPS based on WHO's guidelines through school characteristics, and to identify the schools' need among six areas of HPS. Methods: A stratified and random cluster sampling design was used to obtain a cross-sectional sample. A total of 59 elementary, middle and high schools in Seoul and Gyeonggi areas were included, and 333 teachers (males 40.6%, females 59.4%) participated in this survey. A self-reported questionnaire consisted of ten items for input for HPS, 50 items for the evaluation of HPS and three items for the schools' needs among six areas of HPS. Data was analyzed through a t-test, ANOVA, and a Duncan test. Results: The mean score of input for HPS was 48.5 ($\pm$15.3). Elementary schools had higher mean scores of input than middle schools. The mean score of schools with a management committee was higher than those schools without it. The schools which had meetings on health issues had higher mean scores. The mean score for HPS was 76.8 ($\pm$9.4): the area of "School Physical Environment" had the highest score (80.0$\pm$10.9), and the area of "Community Relationships" had the lowest score (67.1$\pm$13.9). Elementary schools had higher mean scores of HPS than middle and high schools. The schools which had less than nine classes and more than 31 classes had higher mean scores. The mean scores of schools with less than 340 students and more than 1201 students had higher. The schools which had meetings on health issues had higher mean scores. The same results were found on six areas of HPS. The teachers responded that the areas of "School Health Policy", "The School Physical Environment", and "Health Service" should be supported among the six areas of HPS. Conclusion: Based on these results, more concerns and support for school health are necessary. Middle schools should give more regard on the development of HPS. For comprehensive school health promotion, all six areas of HPS should be equally supported.

The establishment of big data service environment requires both cloud-based network technology and clustering technology to improve the efficiency of information access. These cloud-based networks and clustering environments can provide variety of valuable information in real-time, which can be an intensive target of attackers attempting illegal access. In particular, attackers attempting IP spoofing can analyze information of mutual trust hosts constituting clustering, and attempt to attack directly to system existing in the cluster. Therefore, it is necessary to detect and respond to illegal attacks quickly, and it is demanded that the security policy is stronger than the security system that is constructed and operated in the existing single system. In this paper, we investigate routing pattern changes and use them as detection information to enable active correspondence and efficient information service in illegal attacks at this network environment. In addition, through the step-by -step encryption based on the routing information generated during the detection process, it is possible to manage the stable service information without frequent disconnection of the information service for resetting.

A new cultivar 'Daewang' strawberry was developed by the National Institute of Horticultural & Herbal Science for forcing culture in 2010. The cultivar 'Daewang' was originated from the cross between 'Maehyang', a high firmness cultivar and 'Wongyo 3111', a high sugar content in 2006. The cultivar shows erect plant type, vigorous growth habit, early flower bud differentiation with 12-15 flowers per cluster from planting on healthy nursery. Fruits of 'Daewang' are conical type having a bright red skin color, and 16-17 g in an average weight. 'Daewang' is suitable for forcing culture as time required for dormancy breaking ranged between 50 and 100 hours. This cultivar has excellent taste for high sugar/acid ratio as sugar content of $11.1^{\circ}Brix$, acidity of 0.39% with abundant texture and can be harvested by late spring because the fruit firmness of 'Daewang' was $18.2g{\cdot}mm^{-2}$ that was about $7.9g{\cdot}mm^{-2}$ higher than $10.3g{\cdot}mm^{-2}$ of 'Akihime' cultivar. But although total yield is not significantly different from 'Akihime' cultivar, its marketable yield is remarkably higher than that of 'Akihime' cultivar. Disease and pest resistance of 'Daewang' have a tendency to sensitive powdery mildew, anthracnose and spotted spider.

BACKGROUND/OBJECTIVES: Despite successes recorded in combating iodine deficiency, more than 2 billion people are still at risk of iodine deficiency disorders. Rural landlocked and mountainous areas of developing countries are the hardest hit, hence the need to explore and advance novel strategies such as biofortification. SUBJECTS/METHODS: We evaluated adoption, purchase, and consumption of iodine biofortified vegetable legumes (IBVL) using the theory of protection motivations (PMT) integrated with an economic valuation technique. A total of 1,200 participants from three land-locked locations in East Africa were recruited via multi-stage cluster sampling, and data were collected using two, slightly distinct, questionnaires incorporating PMT constructs. The survey also elicited preferences for iodine biofortified foods when offered at a premium or discount. Determinants of protection motivations and preferences for iodine biofortified foods were assessed using path analysis modelling and two-limit Tobit regression, respectively. RESULTS: Knowledge of iodine, iodine-health link, salt iodization, and biofortification was very low, albeit lower at the household level. Iodine and biofortification were not recognized as nutrient and novel approaches, respectively. On the other hand, severity, fear, occupation, knowledge, iodine status, household composition, and self-efficacy predicted the intention to consume biofortified foods at the household level; only vulnerability, self-efficacy, and location were the most crucial elements at the school level. In addition, results demonstrated a positive willingness-to-pay a premium or acceptance of a lesser discount for biofortification. Furthermore, preference towards iodine biofortified foods was a function of protection motivations, severity, vulnerability, fear, response efficacy, response cost, knowledge, iodine status, gender, age. and household head. CONCLUSIONS: Results lend support for prevention of iodine deficiency in unprotected populations through biofortification; however 'threat' appraisal and socio-economic predictors are decisive in designing nutrition interventions and stimulating uptake of biofortification. In principle, the contribution is threefold: 1) Successful application of the integrated model to guide policy formulation; 2) Offer guidance to stakeholders to identify and tap niche markets; 3) stimulation of rural economic growth around school feeding programmes.

The purpose of this study is to verify whether the types of welfare attitudes are classified according to the welfare regimes. Specifically, this study tried to confirm whether the satisfaction and needs of the role of government for inequality reduction are divided into welfare regimes. For the purpose, this study conducted a comparative analysis of 24 European countries using the 6th European Social Survey (2012) and the Eurostat data. The main results of the analysis are summarized as follows. First, there is a difference in the satisfaction and needs of the role of government for the inequality reduction among the welfare regimes. Generally, the satisfaction is high in the Nordic countries, while the needs is high in the southern and eastern European countries. Second, there is a correlation that the country where the per capita welfare expenditure level is high and the redistribution effect is strong have high level of the satisfaction. Third, the types of welfare attitudes are classified according to the welfare regimes. In particular, the Nordic countries are converging into a cluster with low needs and high satisfaction. These countries have high level of social spending and strong redistributive effects. This study suggested policy implications based on the above results.

The purpose of this study is to examine work-life balance by analyzing time schedules of married couple. The 2014 Korea Time Use Survey dataset was used for the analysis. Finally, 6,262 time diaries of 3,131 households were included in the analysis. The study used sequence analysis in particular, by applying the Lesnard(2014)'s dynamic hamming matching (DHM) method, which is useful for the time diary analysis where timing is a key factor. This study explored daily schedules of each man and woman according to 9 types of couple-combined work-schedules, which had been already derived by cluster analysis. The daily schedules were identified according to the activities divided as labor, housework, sleep, self-management, active leisure, passive leisure, and others. Here, time allocation was analyzed through various graphs showing average time amount and modal states by time period. Based on the analysis, it summarized that "long working hours as a main factor of work-life imbalance", "gender inequality of time use", "non-standard hours work impairing quality of life and "poverty of leisure time"as characteristics of work-life imbalance. Finally this study discussed the social policy implications to support work-life balance.

The roles and functions of domestic public libraries are diversifying, but various problems have emerged due to internally biased book lending. In addition, due to the 4th Industrial Revolution, public libraries have introduced a book recommendation system focusing on popular books, but the variety of books that users can access is limited. Therefore, in this study, the public library unborrowed book recommendation system was implemented limiting its spatial scope to Duryu Library in Daegu City to enhance the satisfaction of public library users, by using the loan records data (213,093 cases), user information (35,561 people), etc. and utilizing methods like cluster analysis, topic modeling, content-based filtering recommendation algorithm, and conducted a survey on actual users' satisfaction to present the possibility and implications of the unborrowed book recommendation system. As a result of the analysis, the majority of users responded with high satisfaction, and was able to find the satisfaction was relatively high in the class classified by specific gender, age, occupation, and usual reading. Through the results of this study, it is expected that some problems such as biased book lending and reduced operational efficiency of public libraries can be improved, and limitations of the study was also presented.
