중국문화와 인도불교의 대나무 형상 비교 연구

In China, the image of bamboo represents the gentleman, the wise man, and the gods. In addition, ethically, it likens or symbolizes innocence, fidelity, emptiness, virtue, and justice. In contrast, in Buddhist scriptures made in India, bamboo is often used in sentences that symbolize bad things or things. So, in this thesis, among the bamboo images found in the Buddhist scriptures, the negative ones were searched and summarized as follows. 1) The appearance of lush bamboo sticking together is like obsession, the cause of suffering. 2) The bamboo flowers and fruits symbolize sickness and greed. 3) Compare the destruction that anger brings to people to the splitting of bamboo. Since banana tree and reed also have ecological characteristics similar to bamboo, these three plants are always compared to diseases, greed, and anger. 4) It compares the decay of a dead body with an insect eating a bamboo leaf, and a bamboo hole is an example of a dirty place where small creatures are generated. However, the above are completely different from the bamboo in Chinese poetry and prose. In China, the same appearance is interpreted as follows. 1) The luxuriant bamboo stands for justice as they depend on each other to coexist. 2) The bamboo fruits are food for the phoenix. Therefore, its flowers and fruits are an auspicious symbol of the coming of the phoenix. 3) The bamboo is a sacred plant that conveys the Way of Sage because it is made by splitting bamboo to make a bamboo books. As such, it can be seen that the Chinese and Indians had different views on the shape of bamboo. Then there is no need to be caught up in one fixed concept or notion of bamboo. In other words, if you break stereotypes, you can learn various and rich images. A lot of common sense or knowledge that is traditionally and uncritically taken for granted is in fact nothing more than a habit or custom.

This paper describes flow characteristics inside a circular pipe of waste collection piping system. The flow characteristics are analyzed by three-dimensional Navier-Stokes analysis. In numerical analysis, organic waste is modeled using the data obtained by site survey. Throughout the numerical simulation, pressure drop in a waste pipe is obtained and compared to the value obtained by analytical method. The pressure drop obtained by numerical simulation of the organic waste has a good agreement with that of the analytic method. It is noted that the accurate prediction of pressure drop in the waste pipe is very important to determine the performance of turbo blower used in making a suction pressure in the waste pipe. Detailed flow characteristics inside the waste pipe having a diverse geometry are also analyzed and discussed.

神의 과일, 중국의 蟠桃와 서구의 황금사과 비교 연구

장춘석 중국인문학회 2015 中國人文科學 Vol.0 No.61

本論文是比較中國蟠桃和西方黃金蘋果找出它们現代的義意. 桃子代表東方的水果, 蘋果代表西方的水果. 這兩種植物是從原始時代以来兩個民族最喜欢的. 古代中國人和西方人把一般生活當中的水果通過想像力视为带给人間和神的不老長生⋅不老不死的神話東西. 但是這是神的水果, 而不是人間可以获得的水果. 所以不論中國神話和西方神話, 得到或者喫到它的人物都面临不幸的結果. 還有植物學观点上, 在故事里會发现原始時代以女性爲中心來發展的植物栽培文化. 就是说管理栽培不死植物的園子主人是女性. 反正随着時代變化, 桃子和蘋果有不同的命運. 宋代以來桃子漸漸變成淺薄的形象. 反而水果當中蘋果在西方一直占据最高地位. 所以現在西方人常常以黃金蘋果比喩难得的珍貴東西或者事情.所以可以说史蒂夫·乔布斯 (Steve Jobs) 创办的 ‘Apple’ 就是現代的黃金蘋果.

Shape optimization of a transonic axial compressor rotor operating at the design flow condition has been performed using three-dimensional Navier-Stokes analysis and three different surrogate models: i.e.., Response Surface Method(RSM), Kriging Method, and Radial Basis Function(RBF). Three design variables of blade sweep, lean and skew are introduced to optimize the three-dimensional stacking line of the rotor blade. The object function of the shape optimization is selected as an adiabatic efficiency. Throughout the shape optimization of the rotor blade, the adiabatic efficiency is increased for the three different surrogate models. Detailed flow characteristics at the optimal blade shape obtained by different optimization method are drawn and discussed.

This paper describes internal flow of a fuel cell's blower, which is mainly used for detached house and apartment. Test blower is operated by a diaphragm, which has suction and discharge port on the top of the blower. For analyzing the internal flow of the blower, three-dimensional Navier-Stokes analysis is introduced in the present study. Hybrid grid system consisted of hexa hedral, tetra hedral and prism mesh is adopted to describe the complex geometry of the diaphragm blower. Throughout the numerical simulation, it is found that the present numerical modeling for analyzing the internal flow of the test blower is suitable for understanding the unsteady nature inside the cavity of the diaphragm. Detailed unsteady flow is analyzed using the results obtained by numerical simulation.

부모의 양육태도와 성취정서가 학업성취에 미치는 영향

장춘자 大田大學校 社會科學硏究所 2016 社會科學論文集 Vol.34 No.2

본 연구의 목적은 대전소재 고등학생을 대상으로 부모의 양육태도 및 학생의 성취정서가 학업성취에 미치는 영향을 밝히려는 것이었다. 본 연구결과를 요약하면 다음과 같다. 첫째, 부모의 양육태도가 학업성취에 미치는 영향을 분석한 결과, 감독만 학업성취에 정적인 영향을 미치고 애정과 합리적 설명은 학업성취 에 영향을 미치지 않는 것을 확인할 수 있었다. 부모의 양육태도는 학업성취에 별로 영향을 미치지 않는다고 할 수 있다. 둘째, 성취정서가 학업성취에 미치는 영향을 분석한 결과, 즐거움과 지루함은 학업성취에 정적인 영향을 미치고, 불안함만 학업성취에 부적인 영향을 미치는 것을 확인할 수 있었다. 따라서 성취 정서는 학업성취에 영향을 미치는 것으로 확인되었다. 학생들의 긍정적인 성취정서가 학업성취에는 정적인 영향을 미친다는 점을 고려할 때, 학생들의 정서적인 안정을 위해 예체능 교육을 활성화하고, 특성화 고등학교 신설 및 확대, 또는 직업 교육과정을 확대하는 제도적인 뒷받침이 시급하다고 할 수 있다.

SIP 환경에서 확장 CCMP를 사용한 새로운 분산 컨퍼런스 시스템 구조

장춘서,Jang, Choonseo 한국정보통신학회 2016 한국정보통신학회논문지 Vol.20 No.12

CCMP(centralized conferencing manipulation protocol) enables adding and removing conference participants, changing their roles, adding and removing media streams in conference system. In this paper, by using extended CCMP, a new distributed conference system architecture which can be used to multiple servers distributed conference system in SIP(session initiation protocol) environment has been presented. In this study, according to increasing number of participants, a new extended CCMP architecture which can distribute conference system loads to multiple servers dynamically to decrease loads of servers has been designed. This extended CCMP architecture also can add dynamically new servers from the prepared servers pool. Furthermore, new conference information data format which can represent extended CCMP has been designed, and exchange procedures of extended CCMP control messages which can distribute loads between servers have also been presented. The performance of the proposed system has been analysed by simulation.
