Recently, economical withering and environmental pollutions are appearing in the mine area in Taeba다 뭉 jungsun because over 300 coal mines have been closed. We have to consider the coal mine industries as cultural things and improve them through preservation, proper development, recovery of nature and giving them new functions. Therefore, in this study, I suggest the new coal museum, which is connected to existing coal mine industries architecturally, and make the active space, which is able to solve the problems above. In addition, through harmony of things to preserve, recording of history, education about underground resources and connecting to tourist resort such as casino, the museum take an important role as a cultural space and we can expect new functions and values of closed mine area, which is causing environmental and civil problems.

A study on the turbulence enhancement by ultrasonic vibration was dealt with an experiment on flow characteristics with ultrasonic forcing in a jet field of coaxialcircular pipe. A large transparent acryl tank and a coaxial circular pipe nozzle were made for the above research. Experimental data have been obtained using PIV. City water of 25℃ was selected as an experimental liquid and the front flow field of the coaxial circular pipe was divided horizontally as 3 measuring regions to observe characteristics of flow phenomena. Characteristics of fluid flow such as velocity vector distribution, kinetic energy, turbulent intensity and etc. were visualized, observed, examined and considered at 3 kinds of Re No. such as Re=2×10³, 3×10³ and 5×10³. In result, it was proved that ultrasonic vibration affected the enhancement of turbulent flow.

To evaluate the antitum or activity and immune response Bujungikgibang(BJ1GB) studies were done experimentally. The results were obtained as follows: 1. BJIGB extracts exhibited a weak cytotoxicity against SK-OV-3, and SK-MEL-2 cell lines. While it showed cytotoxicity against B16-Fl0 cell line up to 30% of control at concentration of 0.5 mg/ml. 2. BJIGB extracts significantly showed inhibitoty effect on DNA topoisomerase 1 from calf thymus in a dose-dependant manner. 3. BJIGB extracts showed antiadhesive rates against A549, at 30% at 0.5 mg/ml, 60% at 1 mg/ml 4. BJIGB extracts inhibited CAM angiogenesis up to 60%. 5. BJIGB extracts prolonged life span of ICR mice bearing S-180 sarcoma cells up to 130.5%. 6. In FACS analysis, the population of helper T cell was increased weakly, while cytotoxity T cell was decreased insignificantly. 7. The production of nitric oxide in RAW cell stimulated by LPS was incresed at 0.5mg/ml or more in dose dependant fashion as compared with control. 8. Proliferation rate of splenocyte was increased at 0.5mg/ml or more a dose dependant fashion as compared with control. These results suggested that BJIGB extracts might be usefully applied for treatement of cancer and also it was nesessary to do more studies about its mechnisms.

청소년의 인터넷 사용과 정신건강 간의 관계에 관한 연구

권구영,이혜자 한국 정신보건 사회사업학회 2002 정신보건과 사회사업 Vol.13 No.-

본 연구는 청소년들의 과도한 인터넷 사용이 생활의 변화를 가져오고 정신 건강에 부정적인 영향을 미칠 것이라는 전제 하에 중, 고등학교에 재학 중인 청소년 1,429명을 대상으로 그들의 인터넷 사용 유형은 어떠하며, 사용 유형에 따른 정신증상의 차이는 어떠한지 그리고 인터넷 사용 목적과 정신증상 간에는 어떠한 상관관계가 있는지 알아보았다. 그 결과 조사 대상 청소년의 38.5%가 문제 이용자의 범주에 포함되었으며, 남학생이 여학생에 비해 문제 이용 비율이 높았다. 그리고 문제 이용 청소년들은 인터넷 사용 후 생활의 변화, 가족 관계의 변화 등을 경험하고 있었다. 또한 인터넷 사용 유형에 따른 정신증상의 차이를 살펴본 결과 평균 이용자에 비해 문제 이용자들의 정신증상이 모든 하위 차원에서 유의하게 높았으며, 중독 정도를 측정한 점수와 정신 증상 간에도 유의한 상관관계가 있었다. 그러나 문제 이용자들을 대상으로 성별, 거주지 등의 인구 사회학적 배경에 따른 정신증상의 차이를 검증해본 결과 유의한 차이가 없어 인터넷의 과도한 사용은 모든 사용자들에게 보편적으로 영향을 미치는 요인임을 추정할 수 있다. 다만 인터넷 사용 목적이 대인관계나 불건전 정보의 획득이 아닌 경우 정신증상이 다소 낮은 것으로 나타나 인터넷 사용목적도 중요한 변인임을 알 수 있었다. 이러한 결과를 바탕으로, 본 연구에서는 청소년의 과도한 인터넷 사용에 따른 부작용을 방지하고 보다 기능적인 수준에서의 인터넷 활용이 이루어질 수 있도록 전문적인 관심과 개입이 필요하며 다양한 변인의 영향력을 고려한 후속 연구가 진행되어야 함을 제안하였다.

This treatise is about studying the changes in military equipment in developed countries for an improvement in infantry's individual military equipment. To accomplish this research, I have analysed the military equipment from many other countries by collecting documents and pictures. The distinctive feature of current military equipment is that it is miniaturized cause of development in materials and various alloted tasks, standardized in various equipment for universal use, and complex functions in mixture of many equipment. Generally it is judged that there was many effect from the American equipment, and that the Europeans prefer complex and traditional shapes.

This study was conducted to measure and compare the salivary cotinine concentration between smokers and nonsmokers, and to investigate the effect on the exposure to environmental tobacco smoke(ETS) with housewives, living on an apartment of Korea. Saliva samples were taken from all volunteers and salivary cotinine was analyzed by a developed radioimmunoassay(RIA) method. The median salivary cotinine levels were 52.8±12.6 ng/ml and 44.6± 9.7 ng/ml in male smokers and in female ones, respectively, and they were 4.3±2.1 ng/ml and 2.9±3.1 ng/ml in male nonsmokers and in female ones, respectively. In addition, average salivary cotinine levels were 3.8±2.7 ng/ml in housewives from smoking homes and 2.4±2.4ng/ml in ones from nonsmoking homes. Results obtained from the analysis of salivary cotinine demonstrate that smokers had a significantly higher concentration of salivary cotinine than nonsmoker. But, there was no significant difference in the salivary cotinine concentration for housewives living in apartment between with smoking husband and with nonsmoking husband.
