        This study was conducted to investigate the similarity between hemagglutination inhibition (HI) test and enzyme-linked immunosorbent assay(ELISA), the HI titer and mean ratio S/P ratio) of avian influenza virus. To perform this study, the 1,457 sera of layers 21 farms in May, July and September, respectively. As a result of HI test, positive rates were 480 to 422 (92.1%) in May, 494 to 394(79.8%) in July and 483 to 402(83.2%) in September, and the mean antibody titer were 4.6, 4.3, 4.0 to 0.3 decreased, respectively. The positive rates by ELISA, 480 to 475(99.0%) in May, 494 to 485(98.2%) in July, 483 to 472(97.7%) in September, and the mean S/P ratio were 2.319, 2.557 and 2.380, respectively. The result of HI test and ELISA positive 480 to 422(92.1%), 475(99.0%), 494 to 394(79.8%), 485(98.2%) and 483 to 402(83.2%), 472(97.7%). Therefore, ELISA was shown more sensitive compare the HI titers.

        많은 제조 또는 서비스 산업에서는 각 주문에 대해 계약에 의해 허용될 수 있는 최대의 납기지연 일자가 존재하며, 이에 따라 주문자는 허용된 납기지연 일자가 초과된 주문은 취소 할 수 있다. 본 논문에서는 총 가중 납기지연 최소화를 위한 단일기계 일정계획문제를 다루며, 납기가 지연된 주문들에 대해 두 가지 종류의 벌칙금을 고려한다. 첫 번째는 허용한도 내에서 지연된 주문에 대한 납기지연 벌칙금이며, 두 번째는 허용한도를 초과한 납기지연에 의해 발생한 주문취소에 대한 벌칙금이다. 본 연구에서는 기존의 총 납기지연 최소화 단일기계 일정계획문제를 위해 개발된 우선순위규칙을 확장하여 납기지연 한도가 있는 상황에 적합한 우선순위규칙들을 제시하도록 한다.

      • Residual DC characteristics in the IPS-LCD by capacitance-voltage hysteresis method on a polymer layer

        Hyang-Yul Kim,Yong-Je Jeon,Jeoung-Yeon Hwang,Jae-Hyung Kim,Dae-Shik Seo 한국물리학회 2002 Current Applied Physics Vol.2 No.3

        In this research,the image-sticking property in the in-plane switching (IPS)-liquid crystal display (LCD) with residual DC voltagehysteresis method in the IPS-LCDs was measured. It was found that the VHR increased with increasing specic resistivity of uorineLCs. The residual DC voltage decreased with increasing concentration of cyano LCs and decreasing with increasing specic re-sistivity of uorine LCs. Consequently,the residual DC voltage can be decreased by high polarity of cyano LC.. 2002 Elsevier Science B.V. All rights reserved.

        Oriental medicine needs to be armed with theories on health-improvement concept under it and basic data matching its views, in order to participate in the health-improvement service in industrial work places. The Orient medicine health-improvement program defines factors that determine individuals' lifestyle, and provides information and technologies for workers to practice in life. To that end, this research compares and analyzes health-improvement concept and health care, defines relations between individuals' health state and their lifestyle as the basic data needed to perform health-improvement business for workers. 1. The subjects employed for this research is categorized into; by gender, males 52.1% and females 47.9% with no big difference between them; and by age, 20s, 6.1%, 30s. 33.9%, 40s, 34.1%, and 50s, 24.8% with 30-50 accounting for most of it. By marriage status, unmarried represents 7.1%, and married 79.1% with most of them married; by revenue, under one million won represents 3.0%, 1-2 million won 26.4%, 2-2.49 million won 11.2%, above 2.5 million won 11.2%, and 1-2.5 million won a majority. By living location, owned houses represents 65.4%, rented houses 14.7%, monthly-rented 9.5%; and by education, elementary and middle school represent 16.9%, high school and its dropouts 22.6%, and junior college and higher 51.6%, with high school and higher occupying most of the group. 2. By job, office workers and managerial workers represent 12.3%, part-timers 21.0%, manual workers 11.4%, jobless 0.6%, professionals 35.6%, service 0.6%, housewives 8.4%, and equipment/machinery operation/assemblers 10.1%. Of this, jobless and part-timers, totaling three, are dropped from this research. By years worked, 0-3.9 years represents 9.7%, 4-7.9 years 6.7%, 8-14.9 years 18.4%, above 15 years 28.7%, and no respondents 36.5%. 3. The degree of the subjects practicing life-improvement lifestyle, on a scale of 1 to 4, is an average of 2.69, personal relations 3.04, self-realization 2.92, stress management 2.76, nutritional state 2.73, responsibility for health 2.47, and athletic activities 2.18, with personal relations earning the highest points and athletic activities the lowest. As for factors influencing health-improvement lifestyle, there is no significant difference between gender, age, and marriage status. Meanwhile, there is significant difference between revenue, dwelling pattern, education level, etc. That is, higher income-bracket, owned houses, rented houses, monthly-rented houses, and higher-educated, in this order, show higher average in health-enhancement lifestyle. By job, housewives, manual workers, office workers, professionals, equipment/ machinery operation/ assemblers, and part-timers, in this order show higher points, while there is no difference with significance by years worked. 4. Factors that affect health-improvement lifestyle are shown below. Self-realization is influenced by age, marriage status, type of dwellings, and level of education; responsibility for health by type of dwellings; athletic activities by gender and age; nutrition by age, marriage status and type of dwellings; personal relations by marriage status; and stress management by type of dwellings. 5. Areas with high points by job show this: in self-realization, office workers, manual workers, housewives, professionals, equipment/ machinery operation/ assemblers, in this order, show difference with significance; in the area of responsibility for health, manual workers, housewives, equipment/ machinery operation/ assemblers, professionals, office workers and part-timers, in this order, do. In athletic activities, manual workers, housewives, office workers, professionals, equipment/ machinery operation/ assemblers, and part-timers, in this order, show difference with significance; in nutrition, housewives, office workers, manual workers, professionals, equipment/ machinery operation/ assemblers, and part-timers, in this order do; and in stress, hou
