In this paper, we developed the micro NCT system for punching the thin plates, which is driven is driven by the standalone type microprocessor. In order to adjust the alignment between the punch and die in-situ punching procedures, the non-contact type laser sensor for measuring the burr and micro-driving system for punching die with using the differential screw are developed. The height of burr in four directions in the punched hole of test specimen are measured, and the measured data are transferred to the personal computer by RS232C serial communication technology. In the personal computer, by using the graphic user interface type monitoring program and data handling procedures which includes the filtering algorithms, the direction and length of movement of the die position is decided and these data are transferred back to the microprocessor. The microprocessor drives the micro positioning stage based on these data. Even if this method is not a perfect solution for the in-situ alignment in micro punching, but this alignment methodology is accomplished in the same stage just after the punching that we hope to solve the alignment problem in the punching system based on this technology.

We carried out a follow-up study on the students who participated in International Astronomy Olympiad(IAO). We surveyed home and school environment, personal characteristics with regard to four high school student and five college students who participated in IAO from 2002 to 2005. In the home environment variable of science elite students who took part in the IAO, we found out significant corelation between science elites and their parent's educational career. In their personal characteristics, we found out considerably their motivation capacity, intelligent curiosity, flexible and creative thinking ability. This study illuminated that the experience of IAO participation offered the opportunity for the students to gain mare self-esteem and positive confidence on scientific study. The IAO experience is construed to effect greatly the students' future. Through the IAO experience, the participating students are expected to major in astronomy and become excellent astronomers in the future. We expect that the interest of student will increase greatly in the area of astronomy and it will contribute to the substantial development of Korean astronomy. In this respect, with the constant support to the IAO participants, the effort to cultivate outstanding astronomers and follow-up study on those participants of the IAO should be continued.

The primary purpose of this study was to investigate the job characteristics and competencies of a head-cook in contracted foodservice management company, identify the knowledge, abilities, skills and other characteristics (KASO) required to perform the duties of a head-cook, and provide training content and develop training program for job of head-cook in contract foodservice management company (CFMC). A survey instrument including identified KASO was used in the study. The questionnaire was delivered by using e-mail to 165 head-cooks employed by CFMC. The factor analysis resulted in a three-factor structure of the instrument such as 'basic foodservice operation duties' 'personal characteristics' 'managing of expanded duties-menu, customer and business'. This result suggested the education and training program for head-cook in CFMC should be composed of 'basic foodservice operation duties' on 'bulk preparation', 'procurement, inventory management', 'facility and equipment management', and 'sanitation and safety management', 'personal characteristics' on 'personality management' and 'moral duties', and 'managing of expanded duties-menu, customer and business' on 'menu management', 'customer service management', 'cost management', and 'administrative ability'. Therefore, it will be expected that the management of human resources in the contract foodservice industry would be developed by the application of recommended education and training program.

Air-line mask is an important personal protective equipment for workers working under hazardous surroundings in which a fixed ventilation system is difficult to be installed. If the air-line mask make loud noise, works wearing the mask may be faced with health problems such as noise induced hearing loss(NIHL). The purpose of this study is to introduce a low noisy technology for workers using air-line mask. A traditional type air-line has been improved to an advanced air-line mask with lesser noise. In the mask, air suppling conduits consists of multi tubes are placed inside of the front of the safety helmet. The noise level reduced from 80dB(A) to less than 80dB(A) when measured by KS A 0701 method at Center for Safety Inspection, Testing and Certification for KOSHA. It is suitable for related regulation[Article 35 of the Industrial Safety and Health Act(Test of Personal Protective Equipment)]. While workers working in noise level of over 90dB(A), they may expose to 82dB(A) or less when they wear the advanced masks. This type masks can be an alternative for works suffering from loud noise generated by traditional air-line masks.

The major purpose of this study was to identify the differences in priorities of nutrition service needs between the service provider and consumers (general population). Identification of the personal characteristics which influence the priorities of nutrition service needs among the general population was also examined. An interview survey using a questionnaire was conducted to collect the data required for analysis. The questionnaire included the priorities of various nutrition service needs as well as the personal characteristics of the study subjects. The study subjects were 300 residents over 40 years of age, and 15 health workers representing health center service personnel in Kyounggi province. Wilcoxon Rank Sums test were adopted to analize the differences in priority between the service providers and consumers. The results showed that priority of nutrition service needs for provider were significantly different from that of consumer. Gender, age, family type, and education levels of the population were the significant factors affecting the differences in priorities for nutrition service needs among consumers (general population). Out of the results, it could be suggested that consumers need should be considered in developing nutrition services to promote nutrition services utilization in health centers. The results may also suggest that one of the causes for the low utilization rate of nutrition services in health centers was the provider oriented program development regardless of the needs of consumers.
