This paper is a research on the life cycle assessment (LCA) of plastic bag, bottle and container. In order to compare the environmental analysis of plastic, paper, pulp, aluminium, glass and steel material, it is studied by LCA technique from before-discarded step such as the material collection, processing of product, energy and water consumption, and product transportation, to after-discarded step such as waste product transportation, air and water pollutant discharge, waste generation, and treatment and/or disposal of waste. As a results, plastic material has a better environmental assessment than the other materials in before- and after-discarded step. So, plastic material must be newly concerned with a green material, and must be reappraised to the waste-deposit systems.

Up to now all carton packs used for milk container in our country have been imported abroad. With rapid increase of interest on environment and waste recycling, Environmental Societies and Civil Consumer's Organization restart the Use of Glass Bottle for Milk Movement. From preliminary survey result that glass bottle had many advantages in most test items, we chose the glass bottle as substitute for carton pack, and proposed some regulations such as usable range and detailed regulation, etc. Because at this time it is impossible to rebuild whole pack manufacturing process to substitute carton pack to glass bottle, it may be more favorable to use glass bottle for milk packing under some restricted condition such as easy recollection and reusable circumstances. In addition some governmental regulations to promote glass bottle milk productions and sale and to return all used glass bottles are absolutely required in group catering system. If above is impossible, it will be next choice to set up regulations of milk packing as well as to use glass bottle at some position, and adopt a consumer deposit system in order to increase glass bottle usage, which will help environmental protection and economy.

VOD를 위한 적응적 버퍼 감시 알고리즘의 설계 및 평가

박규석,곽달영 慶南大學校 附設 工業技術硏究所 1998 硏究論文集 Vol.15 No.3

VOD 서비스는 연속적인 전송과 클라이언터에서의 중단 없는 재생이 요구된다. 그러나 서버에서 주기적으로 미디어 스트림을 전송하더라도 통신망의 상태에 따라 각 클라이언트가 불일정한 시간 간격으로 스트림을 수신하게 된다. 본 논문에서는 통신망의 상태에 따라 클라이언트 버퍼가 오버런 임계구역을 벗어날 경우 제어 요구신호를 서버에 보내고, 서버의 제어가 이루어지기 전까지 버퍼 상태를 체계적으로 감시하여, 그 상태에 따라 feedback을 보내 네트웍의 상태에 적응적으로 처리하는 알고리즘을 제안하며, 시물레이션을 통해 제안 알고리즘이 기존 알고리즘에 비해 overload가 적으며 feedback의 횟수도 줄어듬을 보인다. VOD service requires continuous transmission and noninterrupted playback for clients. Although a server transfers information streams at fixed intervals, the client may not be able to receive the streams as they were sent due to network traffic or other states. In this paper, we attempt to resolve this problem by checking the client buffer systematically. Suggested algorithm sends the control request signal to server in the case of overrun according to the status of network, and monitor the buffer status systematically before make a server control. And the feedback can deal adaptively according to the status of buffer. We will also show that the suggested algorithm has less overload and less feedback than existing algorithms through simulation.

The objective of this study is to illuminate the value of performance as the source of knowledge in physical Education. In the pursuit of the above research objective the following things were considered; A) The current direction being pursued in physical education was examined. B) An attempt was made to clarify ‘physically derived knowledge’, under the premise that it should be centered as the unique domain of physical education. C) While re-interpreting the concept of physical education based of the premise of ‘physically derived knowledge’ the essential value of physical education was examined. D) The ideal course of development of physical education in relation to the mode of physically derived knowledge and the human originality and realization inherent in this were examined. Ultimately, through a re-eveluation of the current state of physical education we have attempted to illuminate the estrangement of physical education from it's core concern, that is, the value derived from movement by the human being. Futhermore, an attempt was made to identify that aspect of physical education which is unique only to physical education, that is, knowledge derived from human movement or from the physical demension of human existence.

본 연구는 스트레스 반응성에 관한 실태 분석이다. 연구문제에 대한 자료를 얻기 위하여 조선대학교, 전남대학교 2 · 3학년에 재학 중인 인문 ·사회계열 121명, 자연계열119명, fl체능계열 107명으로 총 347명을 모집하였다. '연구내용은 스트레스 반응성을 정서적 반응, 사고과정의 와해, 신체질병, 행동징후, 긍정적 반응 등의 범주로 나누어 각 범주들의 양상과 순위를 확인하고 각 반응의 수준을 양호, 보통, 불량의 수준으로 나누고, 전체별, 계열별, 성별. 차이를 검증하였으며 마지막으로 반응성의 각 범주간의 상관성을 밝혔다. 대학생들이 스트레스에 처했을 때 주로 정서적 반응, 사고과정의 와해, 신체질병을 호소하며 반응성의 각 범주를 양호도수준별로 비교할 때 불량 수준에 있는 반응성 범주는 정서적 반응, 긍정적 반응, 사고과정의 와해 순위이다. 계열별 비교에서 신체질병의 범주는 정서적으로 의미있는 차이가 있어 스트레스로 인한 신체질병을 호소하고 있는 순위는 예체능계, 자연계, 인문 ·사회계 순서이다 타 범주는 의미있는 차이가 없고 대체로 양호한 편에 편제되어 있다. 성별비교에 있어서 행동표시의 범주만이 통계적으로 의미있는 차이가 있다. 즉 여학생이 남학생보다 스트레스 상태에 취하면 행동표시에 높게 반응하는 것으로 나타났다. 스트레스 반응석의 각 범주간의 상관에 ,있어 사고과정의 와해와 정서반응, 신체질병.'과 사고과정의 와해, 신체질병과 정서반응은 높은 상관이 있으며 긍정적 반응과 정서반응, 그리고 긍정적 반응과 사고과정의 와해는 부적상관관계를 나타내고 있다.

The purpose of this study is to investigate the relationship between the student' learning styles and the extent of learning achievement according to their gender and departments. The paper finds 5 types of learning styles and compares them to see if there are any relationship between the students' learning style and G.P.A according to their gender and departmentsdanguage, science and arts-athletics). The results of this study is in substance as follows. ① There is no significant difference in the learning styles according to the students' gender. ② There is only significant difference in learning achievement of WI style of gender 20 difference but no difference in the other styles ③ There are significant differences among the styles of departments but it is feeble to predict G.P.A of freshman with learning styles on departments.
