G code has to be made after changing the drawing information to DXF file, the converting file. When the information is changed, the converted file had the unnecessary time of rapid feed during working and the large DATA capacity. It need for arranging the information ordered irregularly. This CAM program based AutoCAD can be decreased uncomfortableness in contrast to use of each system. Also it can be increased productivity by arranging information. And it can be used easily for the beginner of the minor enterprises. its program can be decreased system error between others by using one system and increased work efficiency by using DCL.

This paper reports the project of arranging archives of Administrative Headquarters of the Jogye Order. It illustrates the whole process of preliminary survey, arrangement, appraisal and description of the archives. One of the distinctive features of the project lies in its focus on practical considerations. In other words, it has avoided blindly following theoretical recommendations made by previous efforts. First step of the project has been to review the current state of the archives through preliminary survey as well as analysis of related regulations. Second step has followed to establish actual process of classifying, appraising, describing, filing and designing storage facility management as well as a computerized archival management system. In this process, every concern has been given to prevent records and archives from physical damage and to ensure their intellectual order kept so that archival information could be re-constructed and usability and efficiency of the records could be secured. Major contributions made by the project can be found in that it has reviewed the volume of administrative archives created and held by Jogye Order and improved the overall efficiency of as well as information sharing among personnel at the Headquarter. The most notable accomplishment could be, however, found in that the project has helped the personnel to rediscover their own history from their records, rather than from their memory. From the theoretical perspective of archival science, the meaning of the project can also be found in that it has provided with the starting point toward establishing organizing methodology for organizational archives including religious archives. Arranging archives of an organization requires archivists to respect theories and principles, but at the same time, adequate attention should be paid to reflect idiosyncratic characteristics of the organization. General methods applicable to a wider range of archives could be derived from the very endeavor. Though impossible in a short period of time, it could be accomplished by accumulating theoretical and practical knowledge and experience.

이 연구에서는 목재의 효율적인 이용의 일환으로 스프루스 직교형적층재의 중층을 중밀도섬유판(medium density fiberboard, MDF), 파티클보드(particle board, PB) 및 배향성스트랜드보드(oriented strand board, OSB)의 3종류의 시판용 목질보드를 복합적층한 3층 목질계 복합적층재(패널)를 제작하여, 중층목질재료라미나의 구성엘리멘트가 복합적층재(패널)의 휨 강도성능에 미치는 영향을 조사하였다. 목질계 복합적층재의 휨 탄성계수는 중층에 배향성스트랜드보드(OSB)를 배열한 복합적층재에서 가장 높은 값을 나타내었고, 중밀도섬유판(MDF)을 중층에 배열한 복합적층재에서 가장 낮은 값을 나타내었다. 이 값은 중층에 섬유직각방향라미나를 배열한 다양한 종류의 직교형적층재 보다 높은 값을 나타내는 것이 확인되었다. 표층이 스프루스 섬유직각방향으로 된 복합적층재의 휨 탄성계수 예측치는 실측치와 비슷한 값을 나타내었으나, 표층이 스프루스 섬유방향으로 된 복합적층재의 휨 탄성계수 예측치는 실측치보다 높은 값을 나타내었다. 복합적층재의 휨 강도는 배향성스트랜드보드(OSB)를 중층에 배열한 타입에서 가장 높은 값을 나타내었고, 파티클보드(PB)를 중층에 배열한 타입에서 가장 낮은 값을 나타내어 휨 탄성계수와 약간 차이를 나타내었다. 복합적층에 의해, 복합적층재의 휨강도 성능의 이방성은 스프루스소재의 그것에 비해 현저히 감소하였고, 보드상호간의 강도성능의 차이도 현저히 감소하는 것이 확인되었다.

도서관 사서의 수많은 업무 중 도서 정리 업무는 사서가 일일이 정리해야 하는 일이기 때문에, 투입되는 인적·시간적 비용이 크다. 이러한 문제를 해결하기 위해 최근 인공지능 기술을 접목한 도서 정리 로봇에 관한 관심이 증가하고 있다. 본 연구에서는 도서 정리 로봇에 적용할 수 있는 다중경유지 최단 경로 알고리즘인 K-ACO 알고리즘을 제안한다. 제안하는 K-ACO 알고리즘은 하나의 로봇이 아니라 여러 대의 로봇을 가정하고 있다. 또한, K-ACO는 개미 알고리즘을 개선하여 K개의 군집을 만들고 각 군집 별 최단 경로를 제공해준다. 본 논문에서는 제안한 알고리즘의 성능 분석을 도서 정리 시간의 관점에서 실시하였다. 제안한 알고리즘인 K-ACO 알고리즘을 한 대학교 도서관에 적용하여 현재 도서 정리 알고리즘과 비교해 보았다. 시뮬레이션을 통해 제안하는 알고리즘은 도서 정리 업무를 치우치지 않고 공평하게 배분하여 궁극적으로 전체 일이 끝나는 시간을 확연히 줄일 수 있음을 알 수 있었다. 본 연구 결과를 통하여 제안한 알고리즘의 적용으로 도서 정리에 필요한 인적·시간적 비용을 절감하여 도서관 내 양질의 서비스 향상을 기대한다.

To examine the following day party and the following evening party in the Man Kyong Jeon, the authors studied“Jin Chan Eui Gue”, which is a historical record published in 1887(King Go-Jong). The results obtained from the study were as follows, 1. There were fixed arranging tables(22) and taking-away tables in the dining table of the following day party. 2. There were fixed arranging tables(5) and taking-away tables in the dining table of the following evening party. 3. Food and flowers were distributed to the 390 attendants in the following day party. 4. There were no distribution of food and flowers to the attendants in the following evening party. 5. Arrangements of the following day party and following evening party were the same as those of the main party. 6. The arranged seat of the King, Go-Jong was facing the south. 7. According to the status or class of the attendant, the pattern or size of table settings were differentiated in the kinds of food, table flowers chinaware etc. 8.

무선 센서 네트워크는 한정된 자원의 센서 노드들로 구성되어 있고, 한번 구성된 후에는 유지 보수가 어렵다는 단점을 갖고 있다. 따라서 무선 센서 네트워크에서는 에너지 소비를 최소화하고, 한정된 자원을 효율적으로 사용하여 네트워크 수명을 최대화하는 것이 중요한 문제이다. 본 논문에서는 클러스터링 방식에서 클러스터 수를 효율적으로 지정하여 에너지 소모량을 최적화하는 기법을 제안한다. 이 기법은 무선 전송에 소비되는 에너지양은 거리(임계값)에 따라 많은 차이가 있으므로 이러한 임계값을 고려하여 클러스터 수를 지정함으로써 에너지 소비를 줄이는 방식이다. 실험을 통하여 제안된 클러스터링 기법은 LEACH(Low-Energy Adaptive Clustering Hierarchy)에 비해 전체 에너지 소모량 측면에서 높은 성능을 나타냄을 확인하였다.

This study was aiming to examine work time, frequency, work environment, and postures of retail grocery store workers to evaluate the risk of musculoskeletal disorders. An ergonomic evaluation was conducted using job analysis and posture analysis. The four most time-consuming tasks were inspecting (27.4%), arranging (21.4%), cutting (17.6%), and displaying (15.6%). The height and length of the shelves evaluated in the field was inappropriate for workers. The most common posture was a standing posture with neutral back, and bent head, right upper arm, lower arms, and hands. Finally, this paper concluded that 'arranging,' 'cutting,' and 'displaying' seemed more stressful than other operations. The result of the ergonomic evaluation would contribute to design a better workspace in ergonomics.

This paper presents a method of self-arranging solderballs by using surface energy difference. After evaporating Au which has high surface energy on Si substrates, Teflon passivation layer which has low surface energy was patterned by lift-off process. Droplets formed only on the hydrophilic Au solderball lands by the surface energy difference, not the hydrophobic Teflon surface. Scattered solderballs sticked by themselves to the wetted solderball lands on the tilted substrate. After setting preheating of $200^{\circ}C$ and soldering of $245^{\circ}C$ hot plates, the solderballs were soldered on the solderball lands and two substrates were soldered together completely. After measuring the mechanical shear strength of the soldered substrates with solderballs of $3{\times}3$, $4{\times}4$ and $5{\times}5$ arrays. the calculated shear strength per one solderball was 1.1~2.4kgf as high as the previous report.

The purpose of this study was to determine the long term effect of a pleasantly designed interior on pro-saptial behavior. For pleasantly designed interior, the existing interior was remodeled through the change of finishing materials for major architectural elements such as wall, floor and ceiling, and changes of furniture and it's arrangement . Pro-spatial behavior was operationalized as seat arranging behavior and measured through the arranged condition and observable arranging behavior. Time-series design, one of quasi-experimental design was used. The data in this study were extracted from an existing field experimental research. Five hundred survey video tapes record during 2 years period were used. In conclusion, the pleasantly designed environment has a long term effect on the pro-spatial behavior change . While self-centered pro-spatial was improved continuously and even reinforced , altruistic pro-spatial behavior was improved but diminished as time passed. There were no differences in the effect between male and female children. The result of the research provide scientific background of an answer to why Interior Design.
