Numerical analysis using three dimensional finite volume method for the discretization, adaptive grid method for the numerical accuracy, multiple rotating frame method for the rotating body and the standard $k-{\epsilon}$ model for the turbulent flow was performed to understand the heat transfer phenomena and to improve the efficiency of the scroll compressor. The temperature measurement was carried out under ARI condition. It was found that the fluid temperature in the compressor was predicted accurately while the temperature of the motor coil showed large discrepancy between the calculation and experiment due to the large anisotropy of the conductivity and non homogeneity. We found that the efficiency of the compressor depends on the inlet temperature of the compressing part and the flow pattern around the inlet region of the compressing part influences the inlet temperature due to high surface temperature of the main frame. The efficiency of the compressor using Coanda effect is higher than the previous one because the smooth suction at the inlet region of the compressing part leads to low heat transfer to the refrigerant of the compressor.

The purpose of this study is to examine the influence of variables such as socio-home environment, social support, and stress in Adolescent. This study was conducted by administering a questionnaire to 530 Adolescents living in Kyeongnam province. The data were analyzed with the SPSS statistical package using cronbach`s α-coefficient, frequency distribution, percentage, pearson’s r-coefficient, and regression analysis. The results of this study are as follows: There were negative correlations between social supports and stress. Furthermore, the higher the family`s economic situation, the greater the degree of social support to the adolescent. When parents have higher expectations for their children`s education the adolescents have better relationships with friends, teachers and their parents and they also have a successful school life. In contrast, when social support was low there was a negative effect on the adolescents lives:their stress level increased. There was less conversation between parents and children. When parents had lower expectations of their children their children had less study time per day. They used computers less often and the children had negative relationships with friends and parents. Social support buffered the related stresses. Finally, adolescent`s stress levels decrease with higher levels of social support.

The main purpose of this study was to examine the effects of interpretive style reading materials on high school students philosophical viewpoints on science. Subjects for this study were 137 girl students in four classes of a high school located in Daejeon city. The classes were divided into two groups: experimental groups and control groups. Students in the experimental groups were administered a series of the reading materials over thirty-six sessions. Additionally, PPP(Philosophical Perspectives Prove) was used in order to assess students philosophical viewpoints on science. Results of the study showed that the interpretive style reading materials takes effect on the change of students philosophical viewpoints on science. At the initial stage, a number of students exhibited viewpoints inclined toward inductivism. As time goes by, however, viewpoint of inductivism was decreased and view of falcificationism and view of relativism were increased. The results also indicated that the effect of intervention was stable.

세탁기용 유도모터의 냉각에 관한 수치적 연구

The numerical study was carried out to effectively cool Induction motor applied to a washing machine.<br/> The outer rotor made of steel periodically spins up and down. The stator consists of the thin layered iron<br/> plates and copper coil. The effective cooling system is necessary to solve the reliability problem caused by the<br/> electric losses at the coil and the iron plate. Because the heat transfer rate of the natural convection in partially<br/> open space is generally low, thus it is necessary to enhance the heat transfer using rotating perforated plate.<br/> The flow phenomena around the motor are very complex due to the motor geometry and the outer rotor<br/> motion. The mixed convection takes place due to the slow rotation speed. The three dimensional flow<br/> simulation was performed using rotating reference frame technique and Boussinesq approximation but the<br/> radiation effect was neglected. It was found that the angle and direction of the cooling blades play an<br/> important role in the stator temperature.

근대 한국 비구니의 선수행(禪修行) 문화와 선맥 전승 연구

임홍경 ( Im Hong-Gung ),홍상욱 ( Hong Sang-Ook ) 한국불교선리연구원 2020 禪文化硏究 Vol.28 No.-

근대 한국 비구니는 교단의 구성원으로서의 숫자나 역할이 비구에 비해 아주 미약한 수준이었다. 조선후기에 이르러서 지방의 비구 고승이 수행하는 산중에 딸린 암자를 중심으로 비구니들의 수가 차츰 증가하였다. 이에 따라 비구니 수행도량이 점차 늘어나면서 비구니교단의 수행가풍과 수행환경이 체계를 갖추기 시작했다. 일제강점기와 한국전쟁을 거치면서 비구니의 역할이 교육, 도량불사, 포교, 복지 등 여러 분야에서 크게 확대되어 가는데도 불구하고 종단내에서 비구니에 대한 제대로 된 평가나 대우는 이루어지지 않았다. 따라서 본 연구는 근대 비구니의 禪修行과 문화, 그리고 선맥전승을 살펴봄으로써 대한불교 조계종의 비구니 수행자로서의 정체성 확립과 종단에 대한 비구니의 역할과 발전방향을 모색하고자 하였다. 개화기 이후 일본불교가 조선에 밀려들어오는 가운데서도 한국 선불교는 중흥을 맞이하였다. 하지만 일각에서는 한국불교의 전통이 왜색화 되어 가는 경향은 계속 되었다. 급기야 만공스님을 비롯한 당대의 고승들을 중심으로 교단의 정통성을 지키고자 하는 움직임이 일어났다. 1921년 선학원이 설립되자 선학원은 불교 전통을 지키는 중심지가 되었다. 특히 당시 비구니들도 이러한 수행전통을 따랐으며 그 가운데 일부의 비구니들은 선학원의 안거에 함께 수선(修禪)하거나 불교전통 수호 운동에 동참하기도 하였다. 이러한 배경 속에서 비구니 대중이 모여서 수행하는 도량이 차츰 설립되었는데 대표적인 비구니 암자로는 해인사의 비구니암자, 수덕사의 견성암, 월정사의 지장암, 대승사의 윤필암 등이 이에 해당한다. 이에 따라 비구니들은 수선안거의 전통과 가풍을 형성하면서 다수의 비구니가 비구 선지식에게 인가를 받음으로써 비구니도 선맥을 전승하기에 이르렀다. 앞으로 비구니들은 선대 비구니의 수행가풍과 전승을 통해서 신심과 지혜를 얻고, 다양하게 변화하는 시대를 살아가는 비구니로서 정체성 재확립이 필요하며 이를 바탕으로 더욱 수행 원력을 굳건히 하여 현시대에 적합한 수행정진의 모습을 보여야 할 것이다. Modern Korean Bhikkhunis (Buddhist nun) were infinitesimal in their number and role as members of the Buddhist denomination. By the end of the Joseon Dynasty, the number of Bhikkhunis gradually increased, which based on hermitages in the mountains developed by Bhikkhu monks in the provinces. As a result, the performance of the bhikkhuni gradually increased, and the practice asceticism style and training execution environment were established. However proper evaluation or treatment of Bhikkhunis had not been conducted within Buddhist organization even though their roles had been gradual expended in various fields such as education, Buddhist monks, missionary work, and welfare. Thus, this study considered Seon practice and its culture, to establish the identity of the bhikkhuni as member of the Jogye Order of Korean modern Buddhism and explored its role and progression in forward. While Japanese Buddhism was flooding into Joseon after the enlightenment period, Korean Seon Buddhism has been great revival. However, there were tendency some part of Korean Buddhist tradition has become similar to Japanese Buddhism. So Mangong and other ancient monks arose the movement in order to protect the legitimacy of the Korean Buddhism, and Seonhakwon was established in 1921, which became center of Buddhist tradition in present. In this background history, Bhikkhunis were also participated in this movement for Buddhist tradition. Under the guidance of a monk, the Seon training environement for Bhikkhunis has been developed and transmission of the SeonMac. Hermitages of Haeinsa Temple, Kyunseongam of Sudeoksa Temple, Jijangam of Woljeongsa Temple, and Yunpilam of Daeseungsa Temple are representative Bhikkuni sailors who are well equipped with the conditions of Seon Practice. In era of diverse changing, it is hoped that Bhikkuni re-establish their identity, and need to get faith and wisdom through the training from the predecessors. Based on this, they will strengthen for their practice and have progress in various aspects in future.
