An environmental problem is the greatest barrier to pursuit of mankinds existence and development. The major traits of this problem are totality and complexity, therefore the finding of environmental problem's solutions is very difficult. The eco-friendly development that pursuing the ecological principles is the direction of environmental problem's solutions. Environmentally sound and sustainable development, deep ecological thought or environmentalism, the following of god's creation order and the old oriental thought are patterns and principles of eco-friendly development. Every creature has one ecological niche from the ecological principles of adoption, competition, evolution, variety, circulation, harmony and equilibrium. Ecological niche means that every creature has ecological status and duty. Therefore finding the mankinds ecological niche is important because it is desirable directions for eco-friendly development to solve environmental problems.

In this paper, we propose a time-varying proportional navigation guidance law that determines the proportional navigation gain in real-time according to the operating situation. When intercepting a target, an unidentified evasion strategy causes a loss of optimality. To compensate for this problem, proper proportional navigation gain is derived at every time step by solving an optimal control problem with the inferred evader's strategy. Recently, deep reinforcement learning algorithms are introduced to deal with complex optimal control problem efficiently. We adapt the actor-critic method to build a proportional navigation gain network and the network is trained by the Proximal Policy Optimization(PPO) algorithm to learn an evasion strategy of the target. Numerical experiments show the effectiveness and optimality of the proposed method.

This study measures the subjectivity of nursing students' experience in community fields through community nursing practice. The purpose of this study is as follows: 1) to find out typologies based on opinions and attitudes toward community nursing practice. 2) to describe the characteristic of each type. 3) to provide alternative strategies for solving community nursing practice problems. A Q-Methodological method was used for that purpose. As a research method, Q-statements were collected through indepth interviews and review of the current literature. For this study 34 Q-statements were selected. 24 nursing students were subjects for the research. The 24 nursing students sorted 34 Q-statements using the principle of Forced Normal Distribution. The principle of Forced Normal Distribution, which has nine scales to measure individual opinions, was called, a Q- Factor Analysis by using a PC Quanl Program to supply the material. According to the results of this study, there were three categories of opinion concerning community nursing practice. The first type is the realistic problem-oriented approach: the second type is the self-responsibility or pursuit of life meaning approach: the third type is the group approach for problem solving. As a result, we need to develop and revise a more realistic way of community nursing practice for nursing students. Finally, the result of this study will provide to the educational program alternative strategies for community nursing practice for nursing students.

This thesis' "Hwang Jae Nai Kyung(黃帝內經)", it is one among Uihak5kyung(醫學五經), is originally total of 18 volumes, the first half of 9 volumes are Somun(素問) and the latter half of the others are Youngchu(靈樞). Also, it is best of old book and literature integrating process of Chinese's medicine. Somun(素問) is comprehensive and extensive principles from fundamental problem of medical science related etiology, pathology, physiology to such parts of preventive medicine as regimen, recuperation. Moreover, therapeutic part of diagnosis and remedy, practice of acupuncture and moxibustion is recorded to Youngchu(靈樞). In the "Hwang Jae Nai Kyung(黃帝內經)", basic system takes precautions and medical cure for disease by approaching not method analyzing body but fundamentals of oriental medicine observed as organizing relation. For the purpose of mixing up beauty based on Buddhism of books, we shall pursuit notion of beauty treatment to method improving health because period flowing is changed to real well-being culture chasing outside beauty and healthy life. Then, to come close for part of oriental medicine and cosmetology, we shall present method of meridian pathways and understand device for cosmetic improvement by analyzing relation to 12 of pathways, the five viscera and the six entrails & skin.

In today's college curriculum, fashion illustration courses are regarded as fundamental sources of knowledge in the fashion industry and the fine arts. The purpose of this study was to critically examine current curricula and educational objectives of fashion illustration courses offered by domestic fashion-related universities and academic institutions, in order to help the development of more effective tertiary level fashion education. Based on the results of data analysis, we suggest the following recommendations: Firstly, university courses should focus on drawing-centered fundamental education. Secondly, design education linked to fashion illustration should be strengthened. Thirdly, creativity-boosting design education is necessary. The range of curricula that could foster creativity and problem-solving skills in professionals should be enlarged, and future education should place emphasis on lateral and creative thinking. The result of this study are expected to contribute to the development of better curriculum in fashion-related education.

A controller of wheeled mobile robot(WMR) based on Lyapunov theory is designed and a Fuzzy-Neural Network algorithm is applied to this system to adjust controller gain. In conventional controller of WMR that adopts fixed controller gain, controller can not pursuit trajectory perfectly when initial condition of system is changed. Moreover, acquisition of optimal value of controller gain due to variation of initial condition is not easy because it can be get through lots of try and error process. To solve such problem, a Fuzzy-Neural Network algorithm is proposed. The Fuzzy logic adjusts gains to act up to position error and position error rate. And, the Neural Network algorithm optimizes gains according to initial position and initial direction. Computer simulation shows that the proposed Fuzzy-Neural Network controller is effective.

The purpose of this study is to compare how different the belief, social support, stress, coping and motivation between the Korean and American children. The data was collected from 157 Korean and 114 American students (5·8th grade). The resets were as follows: 1. Korean children's other dependency and pessimism level was significantly higher than those of American children. Also Korean children perceived higher than American children in the control-pressure stress and elf-respect stress. 2. Pessimism was observed the highest effect factor on Korean children's stress. 3. Korean students tried various coping under the relationship stress. 4. Problem oriented coping was found as an effective coping in Korean children. But the pursuit of support was found as an effective coping in American children.
