The objective of this research is to study the method to produce biotope map by using GIS. Surveying and analyzing the situation of biotope map in the country, it was found that biotope map should be produced to be utilized in establishing urban plan and environment preservation plan. Considering the history of materials, preparation method and type of use, the types of original materials can be classified into 3 types, namely, data based on configuration map, the existing thematic map and materials of surveying natural ecology. Biotope map is composed of configuration thematic map that shows the shape and position of surface, urban thematic map that is the standard of unit biotope shape and urban ecology map that shows the urban ecologic situation. Extracted and processed from the original material, each thematic map is produced as biotope map that shows the type of biotope. It is expected that biotope map can be utilized in the area of urban plan including establishment of basic urban plan and urban management plan as well as environment planning area including evaluation of environment influence, establishment of environment preservation plan, consolidated environment management for natural environment and life environment.

This thesis is the result of the study about 'How we should develop the human resources program to gain human strength in the strategic environment of the future?' Once again, regional stability is interdependent with economic stability, political stability, and military stability of all the factors in the region. History shows that if a militarily capable regime lacks economic resources, then there is political pressure on the regime to use their military to acquire needed resources. The purpose of this study is to find the way that how to gain excellent human resources now and in the future. Military man power should be strong whenever. The Ministry of National Defense has "Reform Military Structure Plan". The focus of this Plan is Korean military strategy in the situation of the confrontation between South and North Korea and in the situation of the international relationship and the way of constructing the military strength for the future. To study these subjects, I reviewed the theories of "Acquisition Program of Human Strength" were developed and assessed the future strategic environment of the Korean Peninsula. From these studies, I suggest that The Ministry of National Defense should pursue preparing for the future military strategy and military structure. we should be skillful in supplementing the Human Strength. We should study about Military Revolution Plan and Human Strength structure for the future.

Under ubiquitous environment, recommendation system is using the collaborative filtering methods by quantifying context information, but insufficient context information can cause inaccurate recommendation result. In order to solve such problems, the researcher used context information and user's profile. But service history information in users' profiles can have the problems of being influenced by change of the user's taste or fashion as time passes by. In addition, context information and user's profile can't be properly inter-locked according to situation, which can cause inaccurate predictability. In this paper, in case a user's taste or fashion is changed as time passes by, the researcher didn't apply bundled-up value to the user's profile but applied different weight according to change of time. And the researcher could solve the problem that context information and a user's profile can't be properly inter-locked according to situation by applying different weight to the result gained by means of collaborative filtering and then by unifying it. In such ways, the researcher could improve predictability.

This paper suggests a car-following algorithm for urban environment, with multiple target candidates. Until now, advanced driver assistant systems (ADASs) and self-driving technologies have been researched to cope with diverse possible scenarios. Among them, car-following driving has been formed the groundwork of autonomous vehicle for its integrity and flexibility to other modes such as smart cruise system (SCC) and platooning. Although the field has a rich history, most researches has been focused on the shape of target trajectory, such as the order of interpolated polynomial, in simple single-lane situation. However, to introduce the car-following mode in urban environment, realistic situation should be reflected: multi-lane road, target's unstable driving tendency, obstacles. Therefore, the suggested car-following system includes both in-lane preceding vehicle and other factors such as side-lane targets. The algorithm is comprised of three parts: path candidate generation and optimal trajectory selection. In the first part, initial guesses of desired paths are calculated as polynomial function connecting host vehicle's state and vicinal vehicle's predicted future states. In the second part, final target trajectory is selected using quadratic cost function reflecting safeness, control input efficiency, and initial objective such as velocity. Finally, adjusted path and control input are calculated using model predictive control (MPC). The suggested algorithm's performance is verified using off-line simulation using Matlab; the results shows reasonable car-following motion planning.

The purpose of this study is to present systematic information and direction to urban underground space development industry, civil engineering and R&D. Regarding the development of urban underground space, the situation in Korea, especially now in Seoul, can be called an underground Renaissance. The Superground project, which has been going on for several years through international competition, is now completed and is about to open the Seoul Architecture Museum. Leading underground space complex development project of Yeongdongdaero, which is the largest living underground space in human history, spectral projects such as the Seoul section of the GTX routes, making underground roads of the Dongbu Expressway and the Seobu Expressway are now speeding up progress. Recently, plans have been made to use the underground more actively through the restructuring project of Gwanghwamun Square, the face of Seoul. And then, patents are indispensable resources for establishing a strategy for R&D as one of the indices showing what technologies have been developed and what technology development will be done in the future. Based on this background, this study attempts to classify and define the technical elements of urban underground space development through the analysis of patents of major countries in the world, and analyze and present state of technology level and situation accordingly.

In this study, we developed education materials using history of science related to the experiment of 'Boyle's air pump' and the Boyle and Hobbs' debate of vacuum to find out the perceptions of NOS by pre-service chemistry teachers. For the study, 29 pre-service chemistry teachers at a college of education in Chungcheongbuk-do were selected. As RFN items that were related to the contextual situation developed in this study, items in the categories of 'Aims and Values', 'Scientific practices', 'Scientific Methods among Educational Applications' and 'Social-Institutional Aspects among Educational Applications' were selected. Through the items of RFN, the perceptions of pre-service teachers in non-contextual situations were investigated. Then we presented the pre-service teachers with the situation related to Boyle's experiment on air pump and Boyle and Hobbes' debate over vacuum. In addition, their perception of NOS was examined in contextual situations related to RFN items. Responses to the items, experimental results related to Boyle's Law, group discussion, and interview data were collected as data. As a result of the study, it was found that pre-service teachers had informed perceptions in most of the items, but cases with naive views or mixed views were found in context experimental situations. This study can contribute to the NOS education for pre-service chemistry teachers by development of context situation education materials related to NOS and by finding out their perceptions in the non-contextual and contextual situation.

This study examines how anonymity between drivers affects aggressive driving and why, in an anonymous situation, some drive aggressively and others do not. Two surveys were conducted. The first survey covered 200 participants and found that people are more likely to drive aggressively in an anonymous situation than in a face-to-face situation. The second survey covered 384 participants with a history of aggressive driving and found that these aggressive drivers could be classified into three groups using a two-step cluster analysis. Drivers who often exhibit aggressive driving in anonymous situations were found in the second questionnaire to have a high tendency towards driving anger and towards ambivalence over emotional expressiveness. The tendency towards self-defensive ambivalence factor, one of the factors in the ambivalence over emotional expressiveness questionnaire, was also found to be high. Individuals who tended to drive aggressively in an anonymous situation were found to be susceptible to driving anger, usually faced ambivalence over emotional expressiveness, and typically were indecisive. The results of this study suggest that rather than intensifying the enforcement of traffic regulations, a better remedy for those who drive recklessly would be to have them undertake some candid self-reflection.

Purpose : This study was to identify the incidence, trend, and situation of the unexpected sudden death of elementary, middle, and high school students in school for 17 years from 1988 to 2004 in seoul. Methods : We used the data of The Seoul Safety Mutual aid Association in seoul. Subjects were 53 unexpected sudden death in school from elementary, middle, and high school students, and we explored the gender, month, a day of the week, year, contents of situation, and medical certificate of death. Statistic analysis were chi-square test, Cochran-Armitage trend test, and the tool was SAS 9.1.Results : There were 53 unexpected sudden death students(male 42 and female 11). The incidence of male students was higher than that of female during 16 years except in 1995. The incidence occurred in middle school students were 31 (58.5%) of 53 and were also most frequent in middle school students in both of male and female students. In 1990, the incidence was 8(15.1%) students, 6(11.3%) in 1992 , and 5(9,4%) in 2000 respectively. The frequency of unsuspected sudden death in March was 11(20.8%) of 53 students, 11 (20.8%) in September, 7(13.2%) in October. In Thursday, it was 12(22.6%) of 53 students. Only 14(26.4%) students of 53 died during general life, but 39(73.6%) were related to excercise. The diagnosis of 14 students died during general life were cardiac arrest 7(50.5%), brain disorder 3(21.4%) which were based on medical certificate. But the diagnosis of 39 students died during or after excercise were brain disorder including cerebral hemorrhage 9(23.1%), heart disease 9(23.1%), cardiac arrest 8(20.5%), and unknown 6(15.4%), respectively. Conclusion : The incidence of unexpected sudden death were more frequent in male students, in middle school, and in excercise-related situation and the trend was similar for 17 years. Therefore, to prevent the unexpected sudden death, it needs to further study substantially the risk factors of unexpected sudden death including past history, life-style, nutrition and development, family history, and learning environment.
