As the OLED industry develops, display equipment is becoming larger. As a result, the stage required for display equipment is getting bigger. This enlargement led to increase in OLED production and industrial development. However, due to the large scale of the stage, other problems due to overheating and overheating caused by heavy load on the linear motor, which is mainly used in the stage, must be solved. In this study, a linear motor equipped with a cooling channel is modeled and the three - dimensional heat conduction flow analysis for this model is simulated using Fluent to analyze the cooling efficiency and cooling efficiency according to the cooling water flow rate. As a result, the cooling channel was effective and the cooling effect and efficiency were the best when the flow rate was about 5 ~ 10 L./min. In addition, the cooling effect is increased when the flow rate is increased, but the efficiency is significantly lowered when the flow rate is more than the predetermined value.

동북아 지역내 경제성장을 끌고 나가는 중국은 해운항만 분야에서는 환적화물의 흐름과 초대형 선박들의 기항지 선택 및 선사들의 네트워크 구축에 대한 영향을 통하여 동북아 단일 시장의 통합을 선도하고 있으며, 지역내 주요 항만들에 다양한 영향을 주고 있다. 이 연구는 중국 주요 항만-상해항, 천진항, 홍콩항 포함-들의 개발과정과 항만들간 개발의 상호관계를 시계열적으로 고찰함으로써 중국 항만의 미래를 조망하는 데에 유익한 시사점을 도출하는 데에 초점을 두고 있다. 주요 항만의 개발과정과 특성은 다음과 같다. 홍콩항은 고베항의 터미널을 세분화 전략보다는 물동량의 증가 추이에 따라 단계적으로 시설을 대형화하는 전략을 취하면서 운영의 안정성을 추구하였다. 상해항은 물동량의 지속적 증가에도 불구하고 2000년대 초까지 확장에 보수적 태도를 견지하였으며, 컨테이너 부두시설을 집중화하여 시설 대형화의 장점을 취하고 있다. 천진항도 타 중국항만과 유사하게 물동량의 증가에 따라 단계적 부두 확충과 부두시설의 집중과 특화 전략을 취하고 있다. 중국 거점항만들에 대한 패널자료와 패널회귀분석은 이들 항만들이 각기 독자적 수요기반을 갖고 있음을 시사하고 있으며, 항만들간 상관관계가 1980년대에는 낮았지만, 1990년대 이후 점차적으로 동시적 상관관계가 높아지는 것을 나타냈다.

The tightness of windows have devoted to the improvement of thermal insulation and energy saving in buildings. But it is known that this tightness causes some side effects such as low ventilation, low capacity to humidity and temperature control and these are not profitable for inhabitants. To act on these side effects, Korean traditional windows which are composed of Han-Ji(Koreand traditional paper) and Chang-Sal(Korean traditional wooden frame) have been studied to get a reasonable solutions for these problems. In this study, to compare the thermal and humidity control performance of current window(12 mm pair) and Korean traditional windows, frames which are made of existing window and Korean traditional windows are adapted to scale model house and then humidity and temperature of in and out of scale model house are measured and analysed. The results of this study are followings ; 1) When Korean traditional window charges 20cm(1/8 of total window area) from total window area, Han-Ji window has higher thermal insulation than that of existing window in daytime. There is the most big thermal difference when double faced with double-ply Han-Ji window is placed to mock-up house. In night-time, the temperature difference is very small so this means that Korean traditional window is good to cover direct sunlight in daytime and reduce the temperature of balcony. One faced with one-ply han-Ji window has the best humidity penetration performance among three type of Korean traditional windows. 2) When Korean window area enlarged to 40cm(1/4 of total window area), the function of 40cm width Han-Ji window is higher than that of 20cm's. This means that enlargement of Han-Ji window cover direct sunlight more and is more efficient in humidity penetration.

Purpose : This study was performed to assess the clinical effect of Daejo-hwan(DJH) on climacteric syndrome, not only common symptoms such as hot flushes, anxiety, palpitation and so on, but also urogenital tract disturbances like vaginal dryness and sexual problems. Methods : We randomly divided 120 women with the climacteric syndrome into two groups. One group received only DJH 2 pills(4g) a time, three times a day for 8 weeks and the other group didn't get any treatment for the same period. We evaluated sonography, DXA, blood test, female hormone test and questionnaires in the beginning as well as after 8 weeks of the treatment. Symptoms were measured by Kupperman's index, Menopausal Rating Scale and the Greene Climacteric Scale. Results : In this study, DJH was innoxious on liver and kidney. And DJH in the treated group reduced climacteric symptoms significantly as compared to the control group without enlargement of uterus myoma and the change of estradiol. In Kupperman's index and MRS, DJH in the treated group especially had effects on fatigue, shoulder pain. anxiety, headache, hot flushes as well as sexual problems. Conclusion : These results suggest that DJH can be useful in treating various climacteric symptoms including sexual problems without influences on the size of uterus myoma and estradiol.

The frequency of breast augmentation surgery continues to increase annually; however, the method of follow-up care varies from hospital to hospital. In particular, many different types of post-operative bras are available in the market. This study evaluated the wearing comfort of various commercial bras that were worn immediately after breast enlargement surgery prior to the manufacture of the bra. According to interviews of medical professionals and market research, five types of brassiere were selected and evaluated by wearing satisfaction, functional performance, and an external appearance test for 6 subjects with breast augmentation surgery. The evaluation questionnaires were based on a 5 point Likert scale with data analyzed using SPSS 20.0. The study results revealed that the bra with the highest degree of satisfaction was CNB (without bra cup) type. However, the use of CNB type showed dissatisfaction in functional evaluation questions regarding breast shaking and material & tactile sensation. In the future, it is necessary to develop a new post-operative brassiere based on a CNB type bra that showed the best evaluation. However, it is also necessary to identify the merits of the other four experimental bras and reflect these advantages.

The enlargement of interest in base isolators as an earthquake-proof design strategy has dramatically accelerated experimental studies of elastomeric bearings worldwide. In this paper, a new base isolator concept that is a hybrid system of rubber bearings is proposed. Uniaxial, biaxial, and triaxial shaking table tests are also performed to study the seismic behavior of a 0.4-scale three-story isolated steel structure in the National Center for Research on Earthquake Engineering in Taiwan. Experimental results demonstrate that structures with a hybrid system of rubber bearings composed of stirruped rubber bearings and laminated rubber bearings can actually decrease the seismic responses of the superstructure. It has been proved through the shaking table tests that the proposed hybrid system of rubber bearings is a very promising tool to enhance the seismic resistance of structures. Moreover, it is demonstrated that the proposed analytical model in this paper can predict the mechanical behavior of the hybrid system of rubber bearings and seismic responses of the base-isolated structures.
