Purpose : The purpose of this study is to know the temperature difference between hysterectomy patients and non-hysterectomy patients. Methods : We studied 45 who had and 45 non-hysterectomy visiting ${\bigcirc}{\bigcirc}$ medical center from January 1st 2010 to December 31st 2010. We measured 3 points temperature of specific acupoints-Chonjung(CV17), Chungwan(CV12), Kwanwon(CV4) by DITI in each group. And then we checked the difference of temperature between CV17 and CV4, CV12 and CV4. For statistics, we used Independent T-test and SPSS version 17.0 for windows. Results : There is no statistically differences between hysterectomy group and non-hysterectomy group on CV17, CV12, CV4 and CV12-CV4 temperature. There is statistically significant difference between group and group on CV17-CV4 temperature. Conclusion : The result showed that the difference between Chonjung(CV17) and Kwanwon(CV4) is higher in group than non-hysterectomy group. Further study will be needed.

Hybrid insulators that have the advantages of both porcelain (high mechanical strength and chemical stability) as well as polymer (light weight and high resistance to pollution) insulators, can be used in place of individual porcelain and polymer insulators that are used for both mechanical support as well as electrical insulation of overhead power transmission lines. The most significant feature of hybrid insulators is the presence of porcelain/polymer interfaces where the porcelain and polymer are physically bonded. Individual porcelain and polymer insulators do not have such porcelain/polymer interfaces. Although the interface is expected to affect the mechanical/electrical properties of the hybrid insulator, systematic studies of the adhesion properties at the porcelain/polymer interface and the effect of the interface on the insulation characteristics and electric field distribution of the hybrid insulator have not been reported. In this study, we fabricated small hybrid insulator specimens with various types of interfaces and investigated the effect of the porcelain/polymer interface on the microstructure, insulating characteristics, and electric field distribution of the hybrid insulators. It was observed that the porcelain/polymer interface of the hybrid insulator does not have a significant effect on the insulating characteristics and electric field distribution, and the hybrid insulator can exhibit electrical insulating properties that are similar or superior to those of individual porcelain and polymer insulators.
항해사의 피로가 해양사고에 미치는 영향 평가에 관한 연구

최근 국내에서는 연간 약 600여건의 각종 해양사고가 발생하고 있다. 해양사고의 발생에 관한 국 내외 많은 연구와 분석에 의하면 해양사고의 약 70~80%가 인적요인에 의해 발생하고 있다. 여러 인적요인 중에서도 항해사의 피로는 매우 중요한 요인이다. 항해사의 피로가 해양사고에 중요한 역할을 한다고 인식되고 있음에도 불구하고 항해사의 피로도를 정량적으로 파악할 수 있는 연구는 거의 미미하다. 따라서 본 연구에서는 해양사고 종류별로 인적요인에 의한 발생률을 분석하고, 문헌과 5점 척도를 이용한 설문조사를 통하여 항해사의 피로에 영향을 미치는 중요한 5가지 요인을 추출하였다. 그리고 ISM법을 이용하여 피로요인에 의한 해양사고 발생 위험성의 평가요소를 계층구조화하였다. 마지막으로 AHP법을 이용하여 추출된 각 피로요인의 중요도를 구하고 항해사의 피로에 의해 발생할 가능성이 높은 해양사고의 순위를 결정하였다. 그 결과 수면시간 0.386, 스트레스 0.302, 건강상태 0.139, 휴식시간 0.099, 음주 약물 0.074순으로 높은 것으로 나타났다. 또한, 인명사상사고 0.328, 충돌사고 0.308, 좌초사고 0.195, 침몰사고 0.094, 화재사고 0.075로 나타났다. 따라서 중요도가 높은 요소들을 중심으로 제어방안을 마련해야 할 필요가 있다. Recently, about 600 cases of marine accidents occur annually in Korea. According to many studies and analyses on occurrence of marine accidents, 70~80% of marine accidents were caused by human factors. Among the human factors, navigation officers' fatigue is very important factor. Although navigation officers' fatigue serves as an important role in marine accidents, there is no method to exactly examine the degree of officers' fatigue. Accordingly, this study analyzed human factors according to types of marine accidents and extracted important five factors affecting navigation officers' fatigue through the questionnaire survey by means of literatures and 5-point scale. In addition, evaluation factors of marine accident risks caused by fatigue factors were divided and structured by using ISM. Lastly, it found out the importance of each fatigue factor drawn by AHP and decided marine accidents that were most highly caused by navigation officers' fatigue in order. At the result, weights were high as sleep time 0.385, stress 0.302, health condition 0.139, rest time 0.099, alcohol and drug 0.074 in fatigue factors, and death and injury 0.328, collision 0.308, grounding 0.195, sinking 0.094, fire accident 0.075 in evaluation factors of marine accident risks. Therefore, the control plan to lower marine accident risks should be prepared on the basis of high weight factors.

Gross-to-net ratio is the important factor determining size of the building. However it was determined as the empirical method without the exact basis in the existing planning. This paper proposes more accurate methods for determining the gross-to-net ratio of architectural planning in general hospital. This paper analyzes the difference of gross-to-net ratio according to the various conditions and presents the elements of influencing on gross-to-net ratio. These elements is evaluated by applying in the typical hospital case. In conclusion, gross-to-net ratio is influenced by the accuracy of the space program, form type of the space and correspondence potential about the internal variation. In addition, This study has proved that empirical approach is a standard of minimum area.

3D rendering tool is based in ray tracing theory. So it can be made use of investigating the phenomenon of a light reflex. But we have to prove it to be the same result with a real phenomenon before the use of it. In this study I will try to prove it and to research the methodology of 3D rendering tool.

The purpose of this study is to analyze proposed the improvement plan of space-program of public space and mechanical/electrical/equipment area in general hospital. We were researched the chronological changes of total floor area plan of public space and mechanical/Electrical/Equipment area. In addition, compared to space-program and actual design drawings of recently general hospitals. Analyze the trend and characteristic of changes in the general hospital area ratio. The results are as follows. The gross to net ratio was set at 1.45-1.55 but increased to 1.53-1.64 in actual drawings. Thus the total floor area increased or net floor area decreased to secure public area, which means the public area planning suggested by the space program cannot accommodate the public space, vertical circulation and facility space required in the modern medical environment. Thus there is a need to reflect the recent trend, above 1.60. Machine/electricity rooms are judged to be planned above 15% of the total floor net area. However, the suggested standards are the required area at the present moment, which requires continued tests and supplement.
