The purpose of this study is to analyze the difference of perceptions between government officials and citizens on outdoor signboards of community centers. For the analysis, the characteristics of signboards were classified into color, number, position, size, form, material, attention and information transfer effect, font size, number of letters, and typeface. The classified characteristics of signboards were empirically analyzed to examine how the overall satisfaction of outdoor signboards has been changed according to the satisfaction on the individual characteristics. In particular, we analyzed how the determinants of officials differ from citizens. As a result of empirical analysis through ordered logit model, the color, number, size, and material of signboard were statistically significant associated with public officials’ satisfaction. With regard to citizens, the number, position, attention, and typeface of signboards were statistically significant. associated with the level of satisfaction Based on the results of the empirical analysis, it is necessary to consider the number of signboards and design in replacement project of community center signboard in the future.

The purpose of the research is to understand the effect of socio-economic characteristics of the locals on their awareness on urban safety through empirical analysis. Specifically, the study focuses on two metropolitan areas in Korea, Seoul and Busan which represent the capital and non-capital metropolitans, to identify any locational differences affecting the awareness on urban safety. Using the data from 2014 Social Survey, the factors that consist urban safety including natural disaster, traffic accident, buildings & infrastructure, fire, crime risk and overall social safety are accounted as the dependent variables in the ordered-Logit model. The result shows that the awareness for each variable tends to have locational differences; the socio-economic characteristics of the locals affect their awareness on urban safety differently, in the capital and non-capital areas. It was also realized that the awareness on traffic accidents and fire is rather associated with other unknown factors than with socio-economic characteristics, and further research is recommended. Finally, the socio-economic characteristics of the locals in both metropolitan areas are shown to have the most influence on the awareness on crime risk therefore it is necessary to design customized CPTED applications based on the local socio-economic characteristics of the locals for improved crime reduction and prevention programs.

이명호,구재송,정용환,정연호,Lee, Myeong-Ho,Gu, Jae-Song,Jeong, Yong-Hwan,Jeong, Yeon-Ho 한국재료학회 1999 한국재료학회지 Vol.9 No.11

Zr합금의 재결정에 미치는 Sn 영향을 조사하기 위해서 Zr-xSn (x=0.5, 0.8, 1.5, 2.0wt.%) 합금을 판재로 제조하여 $300^{\circ}C-800^{\circ}C$에서 1시간 동안 열처리하였다. 열처리 온도에 따른 Zr합금의 경도, 미세조직 및 석출물 특성을 미소경도계, 광학 현미경 및 투과 전자 현미경을 이용하여 조사하였다. 냉간가공된 Zr-xSn 합금은 회복, 재결정, 결정립 성장의 전형적인 거동을 나타냈으며, 냉간가공재의 재결정은 $500^{\circ}C$에서 $700^{\circ}C$ 범위에서 완료되었다. Sn량이 증가함에 따라서 합금의 재결정온도는 증가하였고 재결정후의 결정립 크기는 감소하였다. 경도 변화는 미세조직 변화와 잘 일치하는 경향을 보였다. 실험 결과로부터 냉간 가공된 Zr합금의 재결정은 아결정립의 합체 및 성장기구에 의해서 일어나는 것으로 평가되었다. To investigate the effect of Sn on the recrystallization of Zr-based alloys. Zr-xSn (x=0.5, 0.8, 1.5, 2.0wt.%) alloys were manufactured to be the sheets through the defined manufacturing procedure. The specimens were annealed at $300^{\circ}C$ to $800^{\circ}C$ for 1 hour. The hardness, microstructure and precipitate of the alloys with the annealing temperature were investigated by using micro- knoop hardness tester, optical microscope(O/M) and transmission electron microscope(TEM), respectively. The cold-worked Zr-xSn alloys showed the typical behavior of the recovery. recrystallization, and grain growth. The recrystallization of Zr-xSn alloys occurred between $500^{\circ}C$ and $700^{\circ}C$. As the Sn content increased. the recrystallization temperature of the cold-worked alloys increased but their grain sizes after recrystallization decreased. It is suggested that the recrystallization of the cold- worked Zr alloys be occurred by the subgrain coalescence and growth mechanism.

The objective of this research is to provide the basic material for effective hospice care by analyzing the recognition of families who have terminally ill patients over death. To do so, this research is designed to investigate the general tendency toward death and changes after hospice care. To analyse the initial status of the recognition about the death, questionnaires were provided to the families of the terminally ill patients who were taken hospice care from June 1st, 2005 to September 10th, 2005 at Saemmul Hospice. The same questionnaires were distributed to research some changes of the recognition of the death after 3 weeks. As the Data Analysis Methodology, SPSS v.10.0 statistics program were utilized. The summary of this research is as follows. First, by gender, it is analyzed that women have more fear than men in terms of incompetence sense after death. By religion, Christians have less fear than other religious people in terms of fear toward after death and general sense of death. Second, those who experienced deaths of close family members, relatives, friends for the past 3 years have more fear toward the moment of death than those who did not experience it. Third, statistically valid difference was found in terms of fear toward the moment of death, fear toward incompetence, fear toward after death, and fear toward death before and after the hospice care was taken. Based on the result of this research, terminally ill patients' families facing death have shown significant differences on fear and incompetence before and after hospice care was offered. It is necessary that the hospice care should be settled more professionally by expanding the opportunities of hospice care and institutionalizing the system. In addition, hospice activities which are focused on providing hope after death and facing death with dignity and peace should be expanded increasingly as the family members who experienced deaths showed higher degree of fear and powerlessness and Christians have less fear toward death with the help of biblical influence. It is also required that hospice care specialized in recognizing the importance of terminal cancer patients and their families at the same time.

본 연구는 사회학적 범죄이론에 근거하여 도시 지역의 특징과 범죄 발생 간의 관련성을 규명함으로써 효과적인 범죄예방 대책을 수립하는데 도움이 되고자 하였다. 연구를 위하여 지난 8년간(2005~2012) 대검찰청의 범죄데이터와 지역별 통계연보 등을 통한 인구사회학적 데이터를 이용하여 패널데이터를 구축하였고, 부산시의 16개의 구 군을 대상으로 패널모형으로 분석하였다. 분석결과를 바탕으로 범죄 발생을 줄이고, 범죄예방을 위해서는 첫째, 일반적인 범죄 예방책보다는 지역의 특성에 적합한 정책이 필요하다. 둘째, 범죄연구에 필요한 구체적이고, 정확한 범죄데이터를 활용할 수 있는 제도적 시스템이나 정책이 필요하다. 셋째, 앞으로도 사회과학분야의 제도와 함께 도시공학 및 여러 학문들이 연계된 연구의 수행이 이루어져야 할 것이다. This study, based on the sociological crime theory, is to examine the relation between urban characteristics and the incidence of crime, helping establish effective crime prevention measures. For doing so, the study employs crime data from the Supreme Prosecutors' Office and socio-demographic data including the regional Statistical Yearbooks -both from 2005 to 2012- to build the study's panel data, and analyzes the panel model on the 16 subordinate districts in the city of Busan. To reduce the incidence of crime and prevent crimes from occurring based on the analysis results, first, prevention measures specific to each region by its attributes are needed rather than general ones; second, new institutional frameworks or policies are required for utilizing accurate crime data; third, interdisciplinary research in which various fields including urban engineering are associated to that of social science is necessary to further the study.
