박유진(You-Jin Park) 韓國生産管理學會 2015 한국생산관리학회지 Vol.26 No.3

반도체 산업에서 제조비용을 최소화하고 생산성과 수율을 보다 향상시키기 위해서는 새로운 공정기술의 개발뿐만 아니라 효과적인 장비 운영·관리기술의 개발과 적용이 필요하다(박유진과 황하란, 2013). 따라서 모든 반도체 관련 업체들은 보다 효율적으로 반도체 생산장비를 운영하고 관리하기 위해 다양한 활동을 지속적으로 수행하고 있다. 효율적인 장비 운영·관리를 위해서는 우선적으로 반도체 생산장비와 운영(제어)시스템간 또는 반도체 생산장비간의 데이터 통신 네트워크 성능이 매우 높아야 한다. 특히 차세대 반도체 웨이퍼인 450mm 웨이퍼 생산체제로 전환 시, 생산장비와 운영(제어)시 스템에서 발생하는 다양한 형태의 대용량 데이터를 안정적으로 수집·관리하고, 이를 제어하기 위한 시스템을 구축하는데 많은 노력을 기울이고 있다. 따라서 본 연구에서는 반도체 장비 데이터 통신 네트워크의 성능을 나타내는 여섯 가지 지표와 이러한 지표들에 영향을 미치는 세 가지 운영 변수들을 고려하여 통신 네트워크의 성능지표와 운영 변수들의 관계를 통계적으로 모형화한 후, 만족도 함수 최적화 기법과 탐색적 알고리즘들을 이용하여 통신 네트워크 성능을 평가하고 이를 통해 효과적인 네트워크 운영방안을 제시하고자 한다. In semiconductor industries, in order to improve productivity and yield, and also to minimize the production cost, it is necessary to develop effective operation and control techniques as well as to develop noble process technologies. So, semiconductor industries are carrying out diverse activities consistently for managing semiconductor process equipment efficiently. For efficient operation and control of semiconductor process equipment, performance of the data communication network between process equipment and the corresponding operating system or among process equipment must be highly excellent. In particular, when moving toward 450mm wafer fabrication system, semiconductor industries are trying to construct an organized system that collects and controls various and big-sized data generated from both equipment and operating system stably. Thus, in this research, after statistically modeling the relationship between key performance factors of communication network in semiconductor manufacturing system and operating parameters which influence key performance factors, we evaluate the performance of communication network and then propose effective network operating strategy using both desirability function optimization method and efficient heuristic algorithms.

Objectives : The purpose of this study is to examine sleeping patterns and diet patterns of the children in day-care centers in Seongdong-district and to find out the relationships between those two patterns and children growth. Methods : 686 day-care center kids participated in the examination. We measured their heights and weights. We also conducted a questionnaire survey (of them) on their sleeping patterns and diet patterns. Based on the findings, we have analyzed correlations of the factors. Results : 1. We have interviewed 686 children in day-care centers in Seongdong-district. Substantial survey was conducted to 672(14 kids didn't go through regular medical checkups). Their age ranged from 4 months to 120 months and weights covered from 6.20 kg to 50.80 kg with the average of 16.97kg. Their height ranges were from 70.4cm to 140.6cm and the average was 100.76cm. 2. The survey results showed that birth-height affects children's current height. The results from the group of age over 25months and the group covering 2 to 6 years indicated that birth-height affected the current height as well. However, the result from the age group over 37 months showed that birth-height didn't relate to the current height. 3. Results from questionnaires on sleeping patterns indicate that children sleeping longer are taller than the other. Results of other questionnaires showed no substantial relations to height. 4. Results from questionnaires on diet patterns, cold food eating habit affects growth. Conclusions : According to the results above, sleeping patterns substantially affects the growth. In order to find out, however, the specific relations between them, further research would be necessary.

In the domestic nuclear power industry, concern about safety of nuclear power plants is continuously increased with the Fukushima nuclear power plant accident. In order to enhance the safety of nuclear power plants, it is important to ensure that the power plants are operating with proper margin within the original design bases. Margin management is the process of ensuring that the NPP designer and operator are aware of the physical and operating limits, and potential and probability of failure, for each component in the plant. All components are subject to margin considerations, but the most important components by scope and attention are those related to safety-related systems and NPP safe shutdown.
