목적 : 본 연구는 소음에 노출된 남자 근로자를 대상으로 장기간 소음 폭로가 혈청 마그네슘의 농도와 관련이 있는지를 검정하고 이러한 혈청 마그네슘의 농도가 또한 청력저하와 관련이 있는지를 파악하기 위하여 수행되었다. 방법 : 소음에 노출되는 178명의 연구대상자를 청력저하의 정도에 따라 세 그룹으로 분류하고, 구조화된 설문, 신체계측, 혈액검사 등으로 청력저하에 대한 감수성 요인과 혈청 마그네슘 등을 수집하고 측정하였으며, 대상자들의 청력 역치를 측정하기 위하여 청력검사를 실시하였다. 결과 : 본 연구의 결과를 요약하면 다음과 같다. 첫재, 청력저하에 관련된 개인의 감수성 인자라고 알려진 변수인 흡연유무, 나이, 혈압, 헤마토크리트, 콜레스테롤, 혈당 중에서 나이, 이완기 혈압이 단순분석에서 세 그룹간에 차이가 있었고(p〈0.05), 혈청 마그네슘의 농도 또한 세 그룹간에 통계적으로 유의한 차이가 있었으며(p〈0.05) 청력저하가 심할수록 혈청 마그네슘 농도는 낮아지는 경향을 보였다. 둘째, 그룹간의 소음 노출력은 차이가 있었지만 (p〈0.05) 청력보호구 착용상태에는 유의한 차이가 없었다. 셋째, 혈청 마그네슘 농도에 영향을 줄 수 있는 변수인 소음 노출 기간, 마그네슘 함량이 많은 음식의 섭취정도, 스트레스 수준 중에서 소음 노출기간이 혈청 마그네슘 농도와 유의한 상관관계를 보였고(p〈0.05) 노출기간이 길수록 마그네슘의 혈청농도는 낮아지는 경향을 나타내었다. 넷째, 주파수별로 청력저하와 관련된 감수성 요인들에 대한 다중회귀분석 결과 주파수 1,000 Hz에서는 연령이 좌,우측 귀 모두에서 유의한 변수로 채택되었으며 (p〈0.05), 연령이 증가할수록 청력저하가 심해지는 경향을 보였고, 주파수 4,000 Hz에서는 확장기 혈압, 소음 노출 기간, 혈청 마그네슘 등이 청력저하에 대한 감수성 요인으로 채택되었으며(p(0.05), 이완기 혈압이 높을수록, 소음노출 기간이 길수록, 혈청 마그네슘의 농도가 낮을수록 청력저하가 심해지는 것으로 나타났다. Objectivea : This study was conducted to investigate that the chronic noise exposure is associated with decreased serum magnesium concentrations and evaluate whether decreased serum magnesium is associated with noise induced hearing loss. Methods : One hundred seventy-eight male workers exposed to noise were selected and classified three groups by the degree of hearing loss. Hearing threshold levels were less than 30 dB at 1,000 Hz or less than 40 dB at 4,000 Hz In group I, more than 30 dB at 1,000 Hz or more than 40 dB at 4,000 Hz and 15 dB and less of pure tone average[PTA : (500 Hz+l,000 Hz+2,000 Hz)/3] in group II, more than 30 dB at 1,000 Hz or more than 40 dB at 4,000 Hz and over 15 dB of PTA in group III. Results : Serum magnesium concentrations were 2.42±0.26 mg/dl in group 1, 2.35±0.23 mg/dl in group n , 2.26±0.24 mg/dl in group II, respectively and significantly differ-ent between group I and group III (p〈0.01). It was negatively correlated with duration of the noise exposure as correlation coefficient (r) of -0.194 (p(0.05) . Analysis of the multipleregression on hearing threshold levels showed that serum magnesium, diastolic blood pres-sure, duration of the noise exposure were statistically significant at 4,000 Hz (p(0.05) . While only age was statistically significant at 7,000 Hz (p(0.05) . Conclusions : These results suggest that chronic noise exposure may induces decreasein serum magnesium concentrations and that its decreased concentration is related with noise induced hearing loss.

Many studies have been conducted under the grand title as modernization of traditional landscape archit-ectures and there is also growing number of sites where the techniques of traditional landscape architecture have actually been tried. But conventional studies concentrated mainly in theoretical studies of "Kotdam(beautiful wall)", due to its title and scarcity. The studied on the detailed construction methods have been neglected. And what is worse, the wall usually is implamented by the architectural drawing. In the case, due to increase in ghe expenses, the building companies either reduce the size or substituted it with different structures. Thus, in the study, though stuctural issues may be solved with modern methods, it focused on expression of traditional pattern for architectural value and used tile type attaching method which resulted in signif-icant reduction of costs. As a result of the study, efficient way to build traditional pattern of Kotdom is suggested in attaching concept figure, standard model and standard Pumseom(quantity manpower spent per unit).

The purpose of this study was to analyzed what effect Taekwondo training has upon Juvenile trainees in Korea, America, and Spain. to see if there is a significant difference in their Human nature Education. The subject of this study was set up as 547 Juvenile trainees who are including 183 Koreans, 185 Americans and 179 Spanish people belonging to gymnasia in their own countries, and sampling by purpose sampling. The means in this study is used to amend and complemented after confirming suitability of the contents in the questionnaire that is made on the basis of questionnaire Lee Chul Ho(1996). it is used as study means after modified, whether the substance of question is right in fitness and applicability or not, Reliability of the question, the range of Cronbach's a is showed from .7924 to .8450. The method of statistically analysis adapted one-way ANOVA, two-way ANOVA by using SPSS WIN 10.0 Program. The result of this study are as followed : First, it can be seen that American Juvenile and Spanish Juvenile show more significant change than Korean Juvenile in their Human nature Education by the Taekwondo training according to their nationality. Second, it can be seen that Juvenile who have had the Taekwondo training for more than from three to five year show more significant change in their emotion, sociability and attitude towards life than those who have had the same training for more than other period in their Human nature Education according to their Taekwondo training period. Third, as a result of analytic investigation of what effect the same training has upon the change factors in their Human nature Education in accordance with their training period and nationality, it can be seen that the training itself and nationality has the greater influence on them than the training period. Therefore, judging from the above findings, it can be proved that the Taekwondo training has much more significant and positive effect on Juvenile in their change of emotion, sociability and attitude towards life.

이상 열이송로프의 열저항에 관한 실험적 연구

유재복,부준홍,유상신 한국항공대학교 1995 論文集 Vol.33 No.-

본 연구에서는 실험적 관찰을 통하여 2상 열이송루프의 성능을 평가하였다. 상변화를 수행하는 작동유채의 관점에서 실험장치는 열을 받아 작동유체가 증발하는 증발부, 열이송이 이루어지는 단열부, 그리고 대기중에 방열하는 응축부로 구성된다. 2상 열이송루프는 증발부와 응축부의 거리를 멀리할 수 있는특징을 가지고 있는데 본 실험적 연구에서는 증발부와 응축부 사이의 거리를 1.2m로 하였다. 2상 열이송루프의 성능을 평가하기 위하여 시스템의 열저항을 증발부 온도와 대기 온도의 차를 증발부에 가해준 열부하로 나누어준 값을 정의하였다. 시스템의 열저항은 열부하의 증가에 따가 급격히 감소하는 경향을 나타내며, 열부하가 적을때는 작동유체량의 증가에 따라 열저항이 증가하지만 열부하가 크게 증가하면 열저항은 작동유체량의 영향을 거의 받지 않는다. In the present study, characteristics of a two-thermal transport loop are evaluated by the experimental investigation. Expermental setup is primarily composed of three parts: an evaporator where a working fluid is evaporated by heating or heat absorption, a thermal transport section that connects the evaporator and the condenser and a condenser which works as a thermal dissipator. One of advantages of the two-phase thermal transport loop is that the evaporator and condenser can be located separately far away. The distance between the evaporator and the condenser is about 1.2m in the present study. In order to evaluate the performance of the two-phase thermal transport loop the system thermal resistance is defined as the quotient of temperature difference between the evaporator and the ambient temperatures by the heat supplied to the evaporator. The system thermal resistance decreases rapidly as the heat load increases. The system thermal resistance increasesas the quantity of working fluid increases for the low range of the heat load, but the thermal resistance is slightly dependent upon the quantity of working fluid as the heat load increases.

Background: Good documentation of electrical injuries at the time of presentation is very important to emergency management, so this study was designed to investigate the clinical characteristics and the outcomes of patients with electrical injury. Methods: A review of 75 cases of electrical injuries admitted to our hospital via the emergency department over a 4 year period from 1996 to 1999 was conducted. Results: There were 49 patients with high-voltage injuries and 19 patients with low-voltage injuries. All but 4 patients were males, with a mean age of 29.5 years. The most common type of injury was electrothermal burn. The most common point of entry was hand. The average size of burn wounds was 14.5% TBSA in the high-voltage group and 2.5% in the low-voltage group. Forty-nine(72.1%) of the injuries were work related. The number of patients with compartment syndrome was 19, and fasciotomies were performed in all but one patient. Myoglobinuria was noted in 22 patients, but no patient developed acute renal failure due to myoglobinuria. In the high-voltage group, 10 limb amputations were performed. Complication were observed in 12 patients. The most common complication was neurological injury. The average length of hospital stay was 50.7 days in the high-voltage group and 13.8 days in the low-voltage group. The overall mortality rate was 4.3%. Couclusion: Prevention of electrical injuries is very important. Education and compliance with safety measures, as well as basic knowledge and precaution in dealing with electricity, are essential to avoid these injuries.

An inflammatory difference between the gastric antrum, body and fundus was studied in 39 H.pylroi positive duodenal ulcer and 29 H. pylori chronic gastritis patients. Also we studied correlation of H. pylori colony count and inflammatory severity. Patients with newly diagnosed duodenal ulcer and chronic gastritis were endoscoped and two biopsy secimens each taken from the antrum, body and fundus. Although intestinal metaplasia in antrum and inflammatory activity in fundus were more severe in chronic gastritis patients. another inflammatory difference was equally likely to be found between two groups. There was no definite histological inflammatory difference between duodenal ulcer and chronic gastritis patients. A positive correlation was found between the number of H. pylori and the severity of inflammation.
