The purpose of this research is to explore ways to improve private security officers' compliance with security policies by analyzing the effects of transformational leadership and organizational trust. Data were collected from private security officers employed in the cities of Seoul and Busan by using survey questionnaire. Statistical analyses were conducted with SPSS 22.0 and AMOS 23.0. The results showed that transformational leadership increased organizational trust which was found to have a positive effect on willingness to comply with security policies. In addition, transformational leadership did not affect willingness to comply with security policies directly but had an indirect effect on it through organizational trust. The findings of current research suggest the leaders of security businesses consider various ways to increase officers' organizational trust such as improved job security and benefits in order to maximize their willingness to comply with security policies.

College tuition is a significant economic, social, and political issue in Korea. We conduct a Bayesian analysis of a hierarchical model to address the factors related to college tuition based on a survey data collected by Statistics Korea. A binary response variable is selected depending on if more than 70% of tuition costs are supported by parents, and a hierarchical Probit model is constructed with areas as groups. A set of explanatory variables is selected from a factor analysis of available variables in the survey. A Markov chain Monte Carlo algorithm is used to estimate parameters. From the analysis results, income and stress are significantly related to college tuition support from parents. Parents with high income tend to support children's college tuition and students with parents' financial support tend to be mentally less stressed; subsequently, this shows that the economic status of parents significantly affects the mental health of college students. Gender, a healthy life style, and college satisfaction are not significant factors. Comparing areas in terms of the degrees of correlation between stress/income and tuition support from parents, students in Kangwon-do are the most mentally stressed when parents' support is limited; in addition, the positive correlation between parents support and income is stronger in big cities compared to provincial areas.

This study examines how individual, familial, and social factors are associated with persistent very low fertility in Busan Metropolitan City and contemplates family-friendly environments and social strategies for fertility increase. Fertility decline in Busan Metropolitan City recorded the lowest birth rate nationwide recent years among metropolitan cities and provinces in Korea. Birthrates are low partly because of multiple factors such as high age at childbearing and at marriage, decline in marriage, high divorce rate, the phenomena of marriage avoidance among unmarried women, traditional gender role attitude of men, low domestic work participation of husbands among dual career couples, low marital satisfaction and family life satisfaction, abortion, and more broader attiributes such as family policy, availability of childcare, education expenses, and family-friendlyness of a society. In addition, women of dual career couples in Busan strained from domestic work overload under traditional norms of gender role, and marital satisfaction recorded below average nationwide along with espeacially low marital satisfaction of wives compared to that of husbands. Major aspects of implications and considerations for higher birth rate and family friendly policy in Busan are discussed.

The purpose of this research is to seek the suggestions applicable to Korean green-growth(development) policy and the realization of low carbon society by looking around the promotion policy and the process, the promotion system, main environmental policy in each city about the business for environmental model city in Japan which has been promoted in a city in order to realize low-carbon society. Japan had selected 13 local governments as an environmental model city as a part of a policy to build low-carbon society in 2008~2009, and Japan has formed information sharing between cities and provinces, the spread of information sharing and the free competition among local governments for an environmental model city through Zero Carbon City Promotion Council consisting of local governments and specialists. When examining these cases in Japan, the green-growth policy promoting currently in Korea needs to be converted from the central government-dominated policy to the local government-dominated policy and Koreaneeds to make more effort to develop software programs in order to realize green-growth social system.

There are many limitations in dealing with rapidly changing traffic demand in urban cities. Thus recently, traffic operation and management skills are more emphasized rather than the expansion of traffic facilities. In particular, in the interrupted flow formed by signalized intersections, it is quite important to give optimal signal timing to each intersection with consideration of progression. However, as fixed signal times per direction can affect passing capacity in signalized intersections, the present four-signal phase including a left-turn signal has many limitations, including reduction of directional road capacity when traffic demand is increases dramatically during peak hours. Because of this problem, lots of studies about internal metering techniques for oversaturated signal control skills have progressed but these techniques are not used widely due to the absence of detectors for queue sensing in real-time signal control systems. In this research, a new methodology called the "restrictive left-turn signal control", which is already used at the intersection above Samsung subway station, is suggested in order to reduce control delay of urban arterial roads. The restrictive left-turn signal control allows a driver to make a U-turn and then a right turn instead of turning left in that intersection. With this change, the restrictive left-turn signal control can contribute to increased intersection capacity by reducing the number of signal phases and maximizing the through phase time. However, road structure and traffic conditions at the target intersections should be considered before the adoption of the proposed signal control.

The knowledge of native wild mushrooms traditionally using in Jeju Island, that have specific native environment and various biodiversity, was investigated. From Jeju and Seogwipo cities including 7 provinces 4 locals, so total 50 villages, data was collected in the entire area and voice of the 93 elderly people between the age of fifty and ninety were recorded. As a result, total 23 native wild mushrooms were used in which 2 species were poisonous mushrooms, 7 species were medicinal mushrooms, 2 species was used for folk religion, 2 species were not used for living but for attention and 12 species were edible mushrooms. Also, a total of 267 cases of traditional knowledge was collected, in which 197 cases were about edible mushrooms for 12 species, 43 cases were about poisonous mushrooms for 2 species, 16 cases were about medicinal mushrooms for 7 species. Interestingly, the fortune for agriculture was told depending on spore mass release of Cyathus stercoreus which grows in animal feces and compost. It is considered as the distinctive traditional knowledge of Jeju Island.

A tick survey was conducted to determine the relative abundance and distribution of ticks associated with selected mammals in the Republic of Korea (ROK) during 2008-2009. A total of 918 ticks were collected from 76 mammals (6 families, 9 species) captured at 6 provinces and 3 Metropolitan Cities in ROK. Haemaphysalis longicornis (54.4%) was the most frequently collected tick, followed by Haemaphysalis flava (28.5%), Ixodes nipponensis (7.6%), Ixodes pomerantzevi (4.8%), Ixodes persulcatus (4.6%), and Haemaphysalis japonica (0.1%). Adults (57.0%) and nymphs (28.7%) of Ixodes and Haemaphysalis spp. were collected most frequently from medium or large mammals in this survey, while few larvae (14.3%) were collected. Hydropotes inermis was the most frequently captured mammal (52.6%), with a 16.4 tick index and 5 of 6 species of ticks collected during this survey. H. longicornis (69.7%) was the predominant tick collected from H. inermis, followed by H. flava (22.2%), I. persulcatus (6.1%), I. nipponensis (1.8%), and H. japonica (0.2%).

Disasters in South Korea are taking on more diverse and intricate aspects than before, while being affected by the industrial development and deterioration of the cities. Therefore, it is urgently needed for success in disaster countermeasures to secure emergency communications operating system which would make it possible to share various information between the control tower and field personnel quickly and accurately. This study proposes a method of improving the national emergency communications operating system based on the Federal disaster management system, emergency communications system, and Standard Operating Procedures (SOPs) employed in the US, which is the leading country in the field of disaster management. First, the organization of the emergency communications needs to be more systematized than in the past. The organization of the emergency communications of the central and local governments have to be administered according to their different roles and objectives. Furthermore, they must cooperate with each other based on interoperability. Second, emergency communications councils need to be established, composed of representatives related to disasters, and national and regional units need to be formed and operated separately. Third, the SOPs should not only cover both the operational and technical elements, but also assign the roles and responsibilities to the members of the disaster communications system. These improvements will assure the correct functioning of the disaster communications system in the field, which is expected to increase the probability of success in disaster countermeasures.

The current status of Korean hospitals on foodservice hygiene was evaluated by a survey in the March of 2000 from 96 hospitals in terms of general sanitation management, education and training, and from 35 hospitals on the observance of hygienic practices in the whole stages of foodservice, personal hygiene, and kitchen equipment and facility hygiene. The questionnaire was filled directly by the dietitian working in the subject hospital. The status of general sanitation management was satisfactory overall; however, the record-keeping or documentation of the practices was the weak point which needs to be improved. only 4% of the subjects appeared to have implemented HACCP for the hospital foodservice. Comparison of the hospitals in their observance rate of hygienic practice by the type of hospital, the location of hospital, the number of bed, and the separation of dietitian's duties as clinical nutrition and foodservice showed characteristic trends among the groups. General hospitals often showed better scores than tertiary hospitals in their observance rates. As the location of hospital moved from large cities to small towns, the observance rate for hygienic practice decreased. Hospitals with entrusted foodservice system showed better scores in hygienic practice than those with owner-operated one in the stage of planning and equipment/facility hygiene (p＜0.05). And the scores of the hospitals having dietitian's duties separated into clinical and food services were higher than the ones with un-separated duties. Detailed information obtained in this study would serve for the development of guidelines or programs to improve the hygienic level of Korean hospital foodservice.

The purpose of this study was to examine the drinking awareness of medical and health-related majors in a bid to find out the impact of their drinking awareness on drinking. The subjects in this study were 153 students who were selected by rendem sampling from colleges located in two different cities in the province. Data collection was performed from may 1 to september 20, 2011 with total 153 college students. Out of them, 86 students majored in medical departments, and 67 students were in the health-related departments. After a self-administered survey was conducted, the following findings were given: A great deal of the students who accounted for 75.8 percent were ever disturbed in daily routine life by drinking over the past year. As for the influence of drinking awareness on the amount of drinking, the amount of drinking was under the significant influence of the following five items. The first was that alcohol was an energizer(p<.001), and the second was that drinking led to a sound sleep(p<.01). The third was that I drank too much with my close friends often(p<.05), and the fourth was that alcohol used as a hangover-chaser was conducive to a hangover(p<.05). The fifth was that alcohol had the largest impact on the liver(p<.05). All the variables made a 43.4% prediction of the amount of drinking. In conclusion, the medical and health-related majors who learned about the impact of drinking on the human body in a firsthand or secondhand manner had a tendency to drink a less amount of alcohol and do less binge drinking. It's advisable to take advantage of the knowledge of medical and health-related majors on the human body and drinking as resources of anti-drinking education.
