The purpose of this study is to develop and evaluate the scale for university students' health behaviors. This research is based on Roger's(1975) Protection Motivation Theory and Weinstein(1988)'s Precaution Adoption Process Model as theoretical frameworks. The contents of the scale were first abstracted from personal depth interviews of qualitative study on university students' health behavior experiences and review of its related literature. The initial items consisted of 76 behavior questions and 34 perception questions. After conducting the preliminary test, 33 behavior questions and 24 perception questions were selected for the final test by revisions on the basis of the result of the content validity test and the item understanding test. The questionnaires for the final test were distributed to 400 students enrolled in three universities. The questionnaires collected from 373 participants were analyzed by the SPSS program. From the examination of construct validity, item correlation, and factor relation turned out to be relevant. Five factors were determined from 27 items with a cumulative explained variance of 54.498 %. After examining reliability and validity of the collected dat, 27 items were finalized as the scale for university students' health behaviors.

As open source can reduce costs and apply to various fields rapidly, many countries have actively adopted open source. However, geo-spatial open source in Korea is not actively promoted yet comparing to other countries having similar infra environments. In this study, we analyzed the perception of geo-spatial open source, utilization status, the development possibility and future direction using questionnaire survey completed by experts dealing with spatial information. The survey result shows that many experts have experiences of using geo-spatial open source but they got a lack of understanding about open source license or regulations and only a few people got professional training. Insufficient references, the difficulty of maintenance, lack of support and low technical reliability have hindered the adoption of geo-spatial open source. Only some part of geo-spatial open source software or libraries in some field have been used in the country. However, many researchers rate highly development potential and plan to use geo-spatial open source soon. If user's convenience, reference materials, technical trust and policy support are improved, open source field for spatial information will be developed greatly in the future.

Necessity of smart work that can change environment of working in organizations has been emphasized. Lots of organizations, however, wish to do work with smartness through adoption of smart work technologies, those are not sure whether smart work will be successful or not till now. Especially, viewpoints of leaders concerning efficiency and effectiveness of smart work who operate the organizations may be different in many circumstances such as industries, characteristics of work, etc. Therefore, hopefully, this research want to investigate whether differences among leader and non-leader group, tendencies of personal leadership styles in work exit or not by empirical and exploratory approach. Totally, 118 questionnaires had been collected and performed test of mean difference between groups. As a result, some items such as working place, working methods, flexible time and tension of smartwork showed significant differences between level of leadership styles and non-leader and leader groups. And, futhermore, from this research I believe that we can have a few insights for successful smart working environment in organizations.

Korea ship management industry originated from overseas seamen employment business since 1963 in the Republic of Korea. Recently, new trend of shipping business has developed in a separate way with ship's ownership and management, that is, cargo business which is in charge of shipowner and practical affairs for ship operation which is in charge of specialized ship management company. Ship Management Industry is being focused as a new development engine with the anticipation of continuous development over 10% a year leading a competitiveness and saving cost in the world market. Therefore, "Draft Ship Management Industry Development Act" was suggested by the shipping business group and academic scholars as a result of continuous research for a long time. This was also submitted to the national assembly for adoption as a national law. The purpose of this paper is to make a contribution to the development of Korea ship management industry through the consideration of each article of this draft Act implications and suggestion of legal and institutional improvements. The result of this study will ultimately contribute to the growth of the Korean ship management industry and enhance their business scope internationally. For the above mentioned purpose, I focus on nurturing and supporting Korea ship management industry, and accreditation of superior ship management industry, etc. within the scope of the submitted draft act.

This research explores the factors affecting infusion of public administrative information systems(IS) and analyzes its impact on work performance. For this purpose, the factors affecting the infusion of IS are classified into voluntary and involuntary motivations based on the self-determination theory that explains individual motivations. As factors for voluntary motivation, performance expectancy, personal innovativeness, and organizational citizenship behavior are proposed, while government influence, competitor influence, and the top-level management influence are proposed as factors for involuntary motivation. The analysis shows the voluntary motivation factors-performance expectancy, personal innovativeness, and organizational citizenship behavior-do affect infusion of IS, whereas the involuntary motivation factors-government influence, competitor influence, and the top-level management influence-have no statistically significant impact on the infusion of IS. The relationship between infusion of IS and work performance is found significant. While individuals are unable to decide on the adoption of IS in an involuntary environment such as in the case of using the public administrative IS, the results show that the factors related to individual autonomy have an important role in extended, active usage of IS beyond the mandatory level.

As a way to gather diverse information required for everyday living, the importance of social networks has been growing. Social network services have been spreading rapidly because of diffusion of the Internet, evolution of social network sites, and recognition of the importance of social networks. Recently, the social network service has been evolved based on a new paradigm, Web 2.0, pursuing participation and openness. Following the adoption of Web 2.0 technologies, the social network service allows users to make and maintain new relationships in a more convenient way. Users of the social network service tend to reveal their personal information, and share their ideas and content with other people; in the process they become aware of their existence, feel satisfaction with life and exert influence to others as a member of the society. This study uses higher order factor analysis to analyze factors that affect the intention of using the social network service. A research model was developed with second-order factors including perceived social presence, perceived gratification and perceived social influence. First-order factors are grouped by technical, individual and social factors. Smart PLS 2.0 was used to conduct empirical analysis. The analysis results supported the validity of the research model.

There has been fast progress in economy in Korea derived by a consecutive five-year plan program for economic development started in the early 1960's. In the field of transportation, rapid changes in the technological environment of transportation and communication have brought a revolution of the transport system, of which inter-modal transportation through containerisation is typical. Because of the rapidly growing traffic volumes of cargo, especially container traffic, and lack of investment into transport infrastructure in the past, both road and railway are beyond their capacity. As a result, the public-road network has suffered a serious congestion problem. For instance, in relation to the corridor between Seoul and Pusan, today, it takes about 14 hours for the journey of container trailer through Kyongbu Expressway, for which it used to take only 7 hours in 1986. For the railway, though the congestion problem is not very serious compared with the road sector, a shortage of capacity on certain main lines has emerged as a problem as railway traffic has increased. Furthermore, the further expansion of the system in near future is difficult due to burden of higher construction the cost. Unlike these two modes, coastal shipping, which has been paid relatively less attention for commodity transport in Korea, shows no constraint in this respect. In addition, it is the most cost efficient mode of transport. This work therefore aims to make a proposal for the alternative inland transportation mode, which is to promote the coastal transport of container. Three obstructing factors for the promotion of the coastal transport are investigated and some solutions for those are suggested as follows : First, it appears to be essential to provide exclusive ports for the coastal shipping, that comply with simplification, specialization and rationalization. The optimum size of berths on the exclusive ports in Pusan port is estimated as 16-20. We found that it needs periodical study and publicity on the advantages from the adoption of the coastal mode. Inducing competition in the coastal shipping market is also necessary. For the supply of the fleet in the coastal shipping, chartering of the surplus ships in the oversea shipping is found to be more desirable than new shipbuilding. Second, to solve the fragmentation of the companies which wish to participate in the coastal transport, government has to implement the subsidy policy. The encouragement of participation of the shipping lines engaging in Korea-Japan run and Korea-East South Asia run, into coastal shipping also needs to be considered cautiously. Third, simplification of the document for entry in ports is needed for rational coastal shipping management. We can use B/L (Bill of Lading) for coastal shipping as a prerequisite to get the indemnity by P & I Club. The reduction of the government controls on entering and leaving the ports also needs.

The changes in the dietary pattern of Koreans during the last one century and its consequences are summarized as follows; 1. Until the beginning of 20th century, Koreans used variety of cereals, vegetables and fruits for their staple food, but the variety has been largely reduced by the agricultural development and urbanized life style. 2. The well balanced traditional dietary pattern of Korean had been deeply deteriorated by the food shortage during the Japanese occupation and Korean war. 3. The deteriorated nutritional condition of Korean was not remedied by the restoration of traditional dietary pattern, but attempted to overcome it by the adoption of Western food habit. 4. The people were trained to eat milk and flour-meals during the starvation of Korean war, and it was continued after Korean war through the animal husbandry promotion policy. 5. The importation of food and feed cereals has been increased rapidly during the economic growth in 1970's and the food self-sufficiency droped below 50%. 6. In 1970's, the food supply pattern of Korean was restored to the level of early 1900, but the consumption of lipid increased extraordinarily. 7. The overconsumption of animal food and lipid continues in 1980's, and it coincides with the rapid increase in the occurence of food related degenerative deseases. 8. The establishment of Korean dietary goal which is based on the traditional dietary pattern is needed.

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.

This study aims to understand the background and characteristics of the UK's allotments, as the UK is one of the nations participating in allotment invigoration. This study will focus on approaches to policy, active governance, and socioeconomic impact. To address this, allotment-related issues, policies since the beginning of the 19th century were analysed. In addition to this, Sheffield City, UK, was selected as a specific case to analyse the framework of allotment management, active governance concerning allotment management, and the residents' perceptions of allotments through a questionnaire survey. It was found first that the UK government, since 1806, has been consistently producing localism policies aiming to devolve management authority into local governments, which actively obtain sites for allotments. Secondly, the structure of allotment management formed in active governance leads the overall maintenance, partnership, income generation, and monitoring of the allotments. Interestingly, the structure of the department organisation of local government in Sheffield established the position of community manager, who encourages community invigoration. However, a gap between socioeconomic aspects was found in which the allotment invigoration in lesser deprived areas outweighs the invigoration in more deprived areas. In contrast, according to the questionnaire survey, respondents in more deprived areas were more likely to be involved in allotment activities and the community. The key to addressing the socioeconomic gap in the context of allotment invigoration is the adoption of the Public-Community-Private-Partnership framework. This will be of great importance to longer-term promotion of beneficial allotment practices.
