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.

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.

This study was conducted to investigate the relationship between the Health Locus of Control (HLC), social support (SS), self-efficacy (SE) and Health Promoting Behavior (HPB) in middle-aged adults and the factors influencing their HPB. Data were collected from 137 middle-aged adults in the cities of Chungbuk and Chungnam for 2 months from July to August 2016 using structured questionnaires. The data collected were analyzed by descriptive statistics, the t-test, ANOVA, Pearson correlations, and multiple regression analysis. The results showed that the HPB varied significantly according to the subjective health (F=10.14, p<.001) and economic level (F=3.32, p= .039) among the general characteristics. In the relationship between the major variables, the HPB showed a significant positive correlation with the SE (r=.44, p<.001) and SS (r=.45, p<.001). A multiple regression analysis was conducted to examine the effects of the general characteristics, HLC, SE, and SS on the HPB, and the results showed that the factors influencing the HPB were the subjective health status (${\beta}=.24$, p=.002), SE (${\beta}=.29$, p<.001), and SS (${\beta}=.30$, p<.001), and these factors showed a combined explanatory power of 36.4%. The results of this study suggest that the SE and SS are important factors affecting the HPB. Therefore, it is necessary to develop and apply a health promotion program reflecting the SE and SS, in order to (promote) the (HPB) of middle-aged adults.

Recently, local government has established a development strategy which takes into account the quality of each area, in order to solve the problems posed by poor development, hindrance of the urban landscape, the limits imposed by relevant laws, etc. However, the number of floors is an important factor which determines the urban landscape, planning density and quality of the external space. This planning factor has a very different effect according to the terrestrial circumstances, number of households, underparking ratio, green space ratio and floor area ratio. Therefore, in this study, a case analysis and case study are conducted and the correlation between each index is clarified. The conclusions of this study are follows. Firstly, flexibility should be ensured by taking into consideration the density indicators, average number of floors, and residential environmental performance measures in related laws and systems. Secondly, it is necessary to develop a wide-area planning method that extends the planning concept from the beginning of planning to neighboring blocks or cities. Thirdly, deregulation measures should be implemented, such as establishing specialized strategies for each region, and regulatory measures for encouraging different types of development.

Purpose - The use of corporate social activities to implement the concept of corporate social responsibility enhances brand equity and attitude, and strengthens economic competitiveness. In areas such as mobile communications, companies take the responsibility of protecting customers and enhance the quality of the mobile communication service, helping to make an effort to obey the regulations of the public trade order and fair trade agreement, enabling a healthy society through communication with elderly living alone or youths without parents, and enhancing marketing strategies. Research design, data, and methodology - To test the hypothesis, a survey was conducted. The surveyed population includes people who use the big three mobile communication services. The survey was conducted from October 4th to October 14th, 2013. A total of 500 survey questionnaires were circulated and 483 were collected; out of these, 32 were excluded due to missing or incomprehensible information. The data was analyzed with SPSS 18.0 via frequency analysis, trust analysis, search factor analysis, relationship analysis, confirmation factor analysis using AMOS 18.0, and structural equation model analysis. Results - Research on corporate social responsibility has been frequently conducted recently. Companies are perceived as social constituents satisfying the social desires of people in addition to customer needs. Further, companies are returning profits to society to satisfy community needs, because there is greater emphasis on the social responsibilities of companies. Companies' social responsibilities should include marketing strategies and the identification of customer needs. This study shows that social service activities influence brand value, which influences customer attitudes; therefore, social service activities indirectly influence customer attitudes. In order to increase customers' purchasing intention, it is essential to improve brand image via social services and provide a distinctive quality of service. Conclusions - This research has used the purposive selection method in the empirical analysis to identify the effect of social services on brand value and customer attitude. Therefore, this study revealed that businesses, whose ultimate objective is to improve customers' purchasing intention, should promote their brand equity through corporate social responsibility activities and offer a distinct service quality. Limitations in the progress of research were found and future indications to overcome these limitations are suggested as follows. First, survey responders had a limited understanding of social responsibilities; therefore, this concept needs to be explained to people first. Second, the research was done on people who live in Daejeon; thus, it is not representative of the entire country. The research has to be repeated with people in other cities. Third, there is a limitation in the study because the purposive selection method was used on Daejeon customers. In the future, a more precise selection of the population is needed. Fourth, Daejeon has unique geographical and size characteristics. Thus, customers in Seoul and other areas may display different characteristics and research on them may reveal different findings. Therefore, again, this study has to be repeated in other areas.

Using the analytical framework designed by Lester, this study analyzes self-governing capacity of ocean environmental management of Busan Metropolitan City pursuing establishment of ocean capital as one of the impending goals. Following Lester's methodology, this study analyzes the levels of two critical variables: will of chief executives and physical base. It was found that mayor of Busan Metrocity and high-level public managers concerned showed somewhat low levels of will, considering Busan is the top-ranked ocean city in South Korea. Comparison of number qf public servants and size of budget for ocean environmental management with seven other metropolitan cities in Korea also revealed that Busan Metropolitan City maintained a relatively low level of physical base. In conclusion, the level of self-governing capacity of ocean environmental management of Busan Metropolitan city is classified into the type of regressives or the type of delayers.
