黃熙喆,閔庚鎭,文勝煜,李萬佶,徐丙天 嶺南大學校附設 基礎科學硏究所 1985 基礎科學硏究 Vol.5 No.-

Five new indans, 5-[3-(N-substitued piperaziny) propxy]indans, were synthesized by condensation of 5-(3-bromopropoxy)indan, the intermediate, and N-substituted piperazines. The structure of the compunds were determined by means of IR, NMR spectoscopy along with elemental analysis. Each compound was tested for antimorphine and antiamphetamine effects as part of CNS depressant effects and for muscle relaxant action in mice. Thes compound exhibited less potent activity compared to chlordiazepoxide on CNS depressant effect. Muscle reaxant action of the compounds, the side effect of tranquilizer, however, was much weaker than that of chlordiazepoxide.

국가정보보호수준 측정 및 활용에 관한 연구

황철중,주용완,민경식,정경호 한국정보사회진흥원 2006 정보화정책 Vol.13 No.3

정보보호 수준을 측정하는 것은 매우 어려운 일로써 정보보호의 영역이 계속 확장됨에 따라 개념자체를 정의하기가 어렵고 아울러 다차원적인 요인을 포함하는 정보보호 지표 선정의 어려움, 시계열적인 통계 데이터 부족, 상이한 정보보호 지표를 하나의 지수로 통합하는 문제가 있기 때문이다. 그럼에도 불구하고 정보보호수준을 계량적으로 측정하기 위한 방법론으로 가장 적합한 것은 지수화하는 것이다. 이는 정책입안자나 정보보호 이해관련자들이 종합적인 측면에서 정보보호수준 목표를 결정하고 실행결과를 평가하는데 용이하기 때문이다. 본 연구의 목적은 정보보호정책 수립 및 평가의 기초 자료로 활용할 수 있는 지수를 산출하기 위한 종합적인 정보보호수준 평가지수 모델을 제시하고 지수를 산출하는데 있다. 지수산출결과, 정보보호수준은 2002년부터 2005년까지를 시계열적으로 보면 매년 평균 5.8%의 증가추세를 보이고 있다. 반면 역기능수준은 2003년 1.25 인터넷 대란으로 증가한 것을 제외하고 꾸준한 감소추세를 나타내고 있다. 특히 정보보호수준과 역기능수준이 발산하고 있어 정보보호정책이 유효하게 작용하고 있다고 판단되어진다.

Marine organisms such as fish (Sebastes schlegeli) and mussels were cultured in sea water tanks placed at Dukpo area which was contaminated by the two oil spill accidents. Results showed that PAHs concentrations in fish tissue were higher than in fish liver. This was explained by the cytochrome P450 IA induction in fish liver after PAHs exposure. Other studies showed that higher PAHs levels were detected in mussels cultures in oil contaminated area than in control site. From these results, we concluded that Dukpo area is still polluted by oil including PAHs and it takes a long time to recover of oil contamination after the oil spill accidents.

In order to perform object measurements of telecommunication systems and devices, it is highly desirable to use the mathematically defined signal reproducing the characteristics of human speech. As the artificial voice must exhibit characteristics as close as possible to real speech, we obtain the statistical characteristics of speech. In this paper, the statistical characteristics are longterm average spectrum, instantaneous amplitude distribution, power envelope spectrum, fundamental frequency and time ratio of voice-unvoice. The statistical characteristics of Korean speech are compared with Japanese's and American English. Such results are useful in adapting speech signal processing technologies developed based on foreign languages.

단일입자분석(Low-Z Electron Probe X-ray Microanalysis)을 이용한 2000년, 2001년에 발생한 황사 입자의 특성분석

황회진,김혜경,노철언 한국대기환경학회 2003 한국대기환경학회지 Vol.19 No.4

A single particle analysis, called low Z electron probe X-my microanalysis was applied to characterize the atmospheric aerosols collected during Asian Dust storm events in the year of 2000 and 2001. Most frequently encountered chemical species were the soil-originated species such as aluminosilicates, silicon dioxide, md calcium carbonate. Also various species such as carbon-rich, organics, sea salts. and some reacted calcium carbonate were identified. The observation of internally mixed particles of calcium carbonate, calcium nitrate and/or calcium sulfate shows the occurrence of the heterogeneous reaction between Asian Dust panicles and NOx and/or SOx, species in the atmosphere.

This study was designed to evaluate gencral features related to allergy of allergic patients living in northern and western Chungchungnamdo, visited to an allergic unit in Soonchunhyang University Chunan Hospital during August 1998 to July 2000. Three hundred allergic patients were enrolled. Among them, 87.7% were outpatients and were analysed for the study. Demographic variables as well as resident living conditions and immunologic results were assessed. Overall IgE, house dust, Dermatophagoides farinae (Df), and Dermatophagoides pteronyssinus (Dp) antibody were assessed using MAST-CLA in 263 outpatients. Relations between allergens and age, sex, and living conditions were evaluated by chi-square tests. Mean age was 21.0 ± 17.3 year-old and male accounted for 59.3% in total subjects. Among them, 52.0% lived in an apartment and 65.3% were from urban area near Chunan and Asan city. Admission rate of allergic patients was 12.3%. The positive rates of total IgE, house dust, Df, and Dp were in 55.1%. 19.0%, 30.0%, and 29.3% in outpatients, respectively. No significant relations between allergens and sex. living home, and region were observed (P>0.05). Adolescents showed significantly higher positive rate of total IgE (P=0.02). Our data suggested that residential environment may not be a significant factor of main causative allergens in northern and western Chungchungnamdo. However more controlled study should be required to elucidate the relations between living environments and major causative allergens in this area.

An Art creates the aesthetic effect through the beauty of form rather than its contents. It is important to perceive how the art exists and functions in the society. The aim of art is to create a true outer form by taking a rational thing out from the inside through the medium of the spiritual activity. Craft concept of the transience of the physical world has very different consequences. The word 'Art' is to be used when it becomes meaningful in the process of an individual transfusing his thought into the senses of others. Aesthetic of art by the style of Modern have generally favoured what has been called the theory of functionally Art. The matter of description of beauty and the interpretation of beauty qualities is based for instance on this double standard. Thus, the aesthetic of Art and functionally art tell us quite a lot of what's going on in our century.

This study was conducted to examine aspects of health service availability and the satisfaction level of clients of public health centers. 351 clients who visited health centers located in Kyungsan, Chongdo, Youngchon, Kyungju, and Pohang were selected as subjects of this study. Data were collected from March 2, 2000 to April 15, 2000. The results of this study are summarized as follows. 1. 89.5% of them had experience in utilizing health services in public health centers. The rate of availing themselves of public health centers by their own decisions was highest (49.4%). 39.8% of them replied that it took below thirty minutes to visit public health centers. 42.2% of them visited public health centers to be vaccinated. 38.0% of them wanted Oriental medicine to be introduced in public health centers. 30.7% of them thought that doctors need go and see patients at their houses and 31.6% of them was satisfied with present office hours. 39.2% of them was not satisfied with the health services because public health centers were ill equipped. 65.1% of them received medical care in public health centers due to low medical charge and 91.0% of them replied that they would visit again public health centers. 35.5% of them thought that medical equipments must be increased to improve health services of public health centers. Each of the above rates were highest in each variables. 2. According to the satisfaction level with health services of public health centers, 35.2% of them was satisfied, while 9.0% of them was not satisfied. 5.7% of them was very satisfied, while 3.0% of them was not satisfied at all. 47.0% of them was satisfied only to a usual extent. 3. The variables, which significantly influenced the satisfaction level with availability of public health centers, were 'reliance on the medical staff (b=0.1749)', 'sufficiency of nurse's explanation (b=0.2093)', 'medical technician's kindness (b=0.1557)', 'simplicity of medical care procedure (b=0.2036)', 'level of medical charge (b=0.1393)', and 'satisfaction with effect of treatment (b=0.1690)'. 4. The variables, which displayed significant correlation with the satisfaction level with availability of public health centers, were 'necessity of doctor's visit to patients' houses (r=0.229)', 'reliance on the medical staff (r=0.488)', 'sufficiency of doctor's explanation (r=0.495)', 'nurse's kindness (r=0.441)', 'sufficiency of nurse's explanation (r=0.458)', 'medical technician's kindness (r=0.326)', 'the staff's kindness in civil service office (r=0.352)', 'simplicity of medical care procedure (b=0.338)', 'environment of waiting room (r=0.283)', 'convenience of availability of subsidiary facilities (r=0.275)', 'level of medical charge (r=0.335)', 'location of public health center (r=0.173)', 'medical facitities and equipment (r=0.217)', 'treatment methods (r=0.294)', and 'treatment effect (r=0.359)'. It appeared that the community residents were somewhat unsatisfied with public health centers because of problems of equipment, treatment sphere, treatment procedure, and medical personnel. Therefore. The government must focus on increase and modernization of medical equipments, the establishment of oriental medicine, and increase of medical personnel. It is important for public health centers to provide community residents with better health services in order to meet their health needs.

The purpose of this study is to identify the scientifical idea of human body in the Enlightening Period in the light of beginning and development of modern gymnastics of Korea with the conflict between traditional thoughts and the western thoughts. Therefore, I tried to clarify the process of the formation and development of Korean gymnastics in the fluctuation of the end of the Dai Han Empire by examining the scientifical idea of human body on anatomy and physiology of the pioneers in the Enlightening Period. As a method of study, Literature approach, the analysis of academic journals of those days was taken as a method of this study. The results of this study can be summarized as below. Anatomy and physiology related to physical exercise, especially anatomy and physiology of human body, was systematically studied. The concept of physiology was established and Heon-Suk Song and 'the monthly bulletin of Buk Seo Academy' detailed the physiology of human body. But the relationship between physiology and gymnastics was poorly explained expert the explanation of the relationship of the number of respiration and the physical status, age, motion, and temperature in 'the Introductory Respiration Physiology'.
