The purpose of this study was to investigate the confirmation and prevalence of porcine cytomegalovirus (PCMV) infection of pigs in Korea using enzyme-linked immunosorbent assay (ELISA). Four hundred-eighty one sera tested were collected from the areas of Kyonggi, Kangwon, Chungcheong, Cholla, Gyongsang and Cheju during the year of 1991 to 1997 except 1994. PCMV antigen, OF-1 strain, for ELISA, was prepared 19-PFT-F cell line originated from porcine fallopian tube. Positive control was used by sera made from the specific pathogen free piglets which were infected with OF-1 strain. Three hundred-sixty seven of 481 sera (76.3%) were positive against PCMV. Antibody titers of these seropositives were classified by 129 (26.8%) cases in more than 1 : 12,800, 77 (16.0%) in 1 : 6,400, 76 (15.8%) in 1 : 3,200, 44 (9.2%) in 1 : 1,600, and 41 (8.5%) in 1 : 800, respectively. Also, the seropositive pigs were divided by 87.4% (76/87) in older than 6 month-old, 73.9% (238/322) in 2~6-month old, and 73.6% (53/72) in less than 2-month old, respectively. Regional prevalence rate of PCMV infection in Korea showed 89.7% (70/78) in Chungchong, 79.8/% (83/104) in Cholla, 79.4% (143/180) in Kyonggi, 79.3% (42/53) in Gyongsang, 50% (15/30) in Kangwon, and 38.9% (14/36) in Cheju area, respectively. In the sera collected in 1991, seropositive rate was appeared as 90.2% (37/41). From 1992 to 1997 except 1994, the average infection rate to PCMV was 77.5%. Consequently, these results confirmed that PCMV in Korean piggeries was introduced at least before the year of 1991. More importantly, PCMV infection has been prevailing nation-wide in pig herds in Korea.

Purpose: This study was done to identify the relationship between smoking, drinking and safety behavior in middle and high school students in one Korean province, North Cholla. Method: The study sample included 1,327 randomly selected middle and high school students from S-Gun area in Chonbuk Province. The data were collected using an anonymous questionnaire developed by the Ministry of Health and Welfare (2005). The data were analyzed using the SPSSWIN 15.0 program. Results: The smoking rate in the middle and high school students was 6.9%, and the drinking rate was 24.9%. The rate for seatbelt use was 49.3%, for drunk driving, 8.8%, and for riding in car driven by a drunk driver, 24.0%. The rates for seatbelt use, for drunk driving, and for riding in a drunk driver were higher in smokers and drinkers than in non-smokers and non-drinkers(p<.05). Conclusion: The smoking and drinking status of the adolescents was correlated with their safety behavior practices as they relate to seatbelt use, drunk driving, and for riding in car driven by a drunk driver. Therefore, an elementary school level program to curb student smoking and alcohol consumption is needed to prevent smoking and alcohol consumption in middle and high school students and contribute to improvement in their safety behavior practices.

The aim of this research is to measure the damage caused by the vibrations of passing trains. In order to determine the vibration levels of the trains, twelve points along the Honam, Cholla and Kyungjun lines were chose. There are two goals to be achieved from the data gathered. The first is to determine whether or not the trains are operating under governmentally determined levels. The second goal is to establish countermeasure in order to minimize the effects of the vibrations on the people who live near the train lines. A vibration level meter was used to measure the vibration levels at all twelve points at times when no trains were travelling and at times when trains were travelling. As a result, it was found that Saemaeulho and Mugunghwaho, had a higher vibration level of 2 - 3 dB than Pidulgiho and freight trans. There were no relationship between speed and vibration level. The vibration levels did change according to capacity and size of the engine. In such cases there was a difference of 2 - 7 dB. Where vibration proof ditches were in place, the vibration level were decreased by 3 - 6 dB. The practical decreases in vibration levels was similar to the theoretical decreases.

This research analyzes results and efficiency to promote a government enterprise of A Korean public enterprise to use DEA. Especially, we were used analysis efficiency which are one is year-on-year, another is integrated, and the other is vertical analysis. As a results of integrated analysis show that Gyeonggi_2003 Gyeonggi_2004, Gangwon_2004, Chungcheon-Bukdo_2003, Chungcheon-Bukdo_2004, Cholla-Namdo_2005, and Kyongsang-Bukdo_2003 need to improve upon. Year-on-year analysis result that Gyeonggi, Gangwon, and Kyongsang-Bukdo need urgent improvement. Today, many advanced countries approach not only agricultural investment but also synthetic investment because they believe that agriculture contains living space including food control. Therefore, when the government make a strategic plan for the land and water development in the field of agriculture, they should prepare it well including the proper measures to cope with the internal and external environments.

The sample consisted of 103 nursing students in the area of Seoul and 143 students in Cholla Province. Data were collected by using a questionnaire, which consisted of items about personnal campus life and their major. The results are summarized as follows: 1. There was on significant difference in campus life adaptation on nursing students between Seoul and local areas. 2. In Seoul area, there was no significant difference in campus life adaptation according to academic years. In local area, significant difference was revealed in the academic years. The scores of campus life adaptation were possitively correlated with their academic years. 3. The variables which can be explained in the regional difference were social recognition of nursing and a family atmosphere. In conclusion, the results of the study indicate that, in Seoul and local areas, the personal and educational backgrounds of campus life adaptation were equalized. In addition, it is very important that the counselling on choice of major should be provided to high school students.
