Multi-Spinner 장비는 반도체 제조공정과정 중 Photo공정에서 노광(Exposure)공정을 제외한 PH 형성공정 및 현상(Development)을 수행하는 복합적인 장비이다. 이 복합적인 Multi-Spinner 장비의 각 수행 과정에서는 웨이퍼를 이동 작업을 하는데 있어서 이동경로를 최적 스케줄링 한다면 반도체 생산량 향상에 크게 도움이 된다. Multi-Spinner 장비내의 각 공정과정들은 PH 형성공정 및 현상 공정 순서에 맞게 순차적으로 진행되며, 이 과정들을 위해 이송 로봇이 순차적으로 웨이퍼를 이동하며 이 과정에서 일정의 대기시간이 발생하게 된다. 대기시간을 줄이기 위해 C/S 유닛에 담겨 있는 수십 장의 웨이퍼들을 다음 공정으로 이송 시 이동경로의 최적 스케줄링이 필요하다. 본 논문은 스케줄링 문제를 풀기 위해 인공 신경회로망(Artificial Neural Network)을 이용한 최적 스케줄링 방법을 제안한다.

An experimental investigation of the natural circulating boiling flow characteristic in three cases of annulus with different outer diameter, and the effect of annular gap size on the burnout behavior is presented. The experimental work was conducted for each case of test section at system pressure of $1kg/cm^2$ and inlet subcooling $0-20^{\circ}C$ in the full range of throttling ratio. As the result, the following facts were found. 1) With the increase of ${\Delta}T_{sub}$, $D_{2}$ and A/A_{o}$, $q_{BO}$ increases on the whole, and with the decrease of ${\Delta}T_{sub}$ and $D_{2}$, hydrodynamic instability is accelerated to happen prematually. 2)With the increase of ${\Delta}T_{sub}$, $D_{2}$ and A/A_{o}$ burnout characteristic shows the high velocitylow quality burnout, and with the decrease, low-velocity-high quality burnout. 3)With the decrease of A/A_{o}$, hyddrodynamic instability is singnificantly restrained and the difference of $q_{BO}$ in each $D_2$ under same condition is gradually reduced, finally converging into $1.9{\times}10^{5}kcal/m^{2}-hr$.

The purpose of this study is to investigate the effective ways of reducing the weight of fat adults. Dietic treatment and athletic treatment have been performed over a four-month period to 73 fat adults who were randomly selected from various walks of life. Through the above approach, following results could be obtained; 1) The effect that dietetic and athletic treatment have on fat adults could be maximized by performing both of the treatments simultaneously, and this method could be applied regardless in their chest circumferences. (Group A : Those who are performing dietetic treatment, Group B : Those who are eating without any regulation)

With 15 selected judo athletes, how their weight control affects and improves their performance of exercise in 5 events exercise(100 running, standing long jump, throwing, chinning, sit-up) was inspected. In order to find out how the quantity of reduction of their weight affects their exercise performance, the effect of weight loss was measured, inspected and analyzed in terms of the quantity of weight loss-i, e., 1kg weight loss. 2kg weight loss, and 3kg weight loss. And findings are as follows: It appeared that in 100m running and standing long jump in the 5 events of exercise, 2kg weight loss resulted in the highest record their exercise; in chinning, 1kg weight loss affected the highest record, and in throwing and sit-up, their usual weight affected the highest record. With this finding, it could be understood that excessive weight loss can bring and result in a boomerang effect of exercise performance, and 2kg weight loss is most effective in helping the improvement of their ability of exercise performance, and therefore in their competiveness in judo games. It is deemed that this research has been a limited one since there were some difficulties in the subject's weight control and in measurement of their physical strength. However, with the importance of weight control being recognized by this research, it is considered that it is necessary to research into the effect of weight control on the athlete's performance in terms of various kinds of athletes or sports, their method to control weight, and the period and level of weight control, in depth, by which the athlete's standard weight control can be generalized.

Multi-valued Resistive Switching Characteristics in WOx/AlOy Heterojunction Resistive Switching Memories

The multi-valued resistive switching (RS) characteristics and mechanism in a WOx/AlOyheterojunction-based nonvolatile memory have been investigated. Although Al/WOx/Pt andAl/AlOy/Pt show different RS characteristics, bipolar and unipolar modes, respectively, theAl/WOx/AlOy/Pt structure shows both bipolar and unipolar RS characteristics, depending on themagnitude of the applied voltage. Three resistance states, which are defined as the low-resistancestate (LRS), the mid-high-resistance state (mid-HRS) and the high-resistance state (HRS), are observed. A model combining two different RS mechanisms, oxygen ions involving the redox processat the interface and filamentary conduction, is proposed, and provides a simple physical concept tounderstand the multi-valued RS behavior. Our findings will be useful to design and optimize oxideheterojunction-based non-volatile RS memory devices.

Purpose of this research is to seek of whether physical education achievement can be attained or not and to aim at activating the basic data on physical education, grasping the knowledges. 1. In illustrating the commonsense athletic outline seen on item, it needs subject of commonsense but showed to be very high on sports of students with most of answer. A valuable part after participation to commonsense physical education was replied that it has large influence enough on sports in personal relation such as social intense and friendship, and consciousness of studying the educated physical education was replied to be worse and finally showed to have much further efforts. In questioning for physical education programme of students, it showed there were a lot of students that theory and practice must be gone studied together, satisfaction on school facilities was very good, to provide opportunity to realize with self to human being about matter of how to see the sports and how to learn moral and spiritual value. In questioning of what is final positive purpose, it answered to form ideal human being together with intelligence and virtue and in question for physical education subject after participating the cultivated physical education, most numerous answers were made after intensive width on personal relation through sports activity. 2. In achieving the posrts purpose, on physical purpose phase, it influenced mostly to behavior physique part such as muscular swift durability and in spiritual purpose part, it felt amicable with soothing one's mind and pressing one's impulse through the games. In social purpose, through physical education, to enhance attitude such as faithfulness, cooperation, obedience, responsibility, and conduct were made in highest answer. After graduation of physical education when selected in relax, in question of what helps, "it helps" showed highest answers, and in question of possibility on how to attain the sports purpose, it made answers mostly of "it did not attain", "it is so" and "it does not know well" and it appeared not to play the role of physical education lesson. After participation of educated physical education, among purposes of physical educations, in whether any part has been mostly developed, it showed most numerous answers on social part and physical flank. In conclusion, it try to integrate theory and practice for effective physical education and has to make up physical education activity to pursue development of athletic ability and healthy society, and to make upon important support on applicable capacity in environmental phase surrounded the physical ability development and human being for the sake of maximal purpose and has to enhance valuable athletic attitude and social attitude to be applied for democratic society. Also, having the righteous value envisage for sports, it activates to life physical education of which is able to make to life and have social life attitude to be expect in future.
