This study was designed to investigate the possible utilization of Zanthoxylum schinifolium as a source of decontamination agents. The antimicrobial effect of Zanthoxylum schinifolium extract was investigated against Vibrio parahaemolyticus which is food-born disease organism. Ethanol extract of Zanthoxylum schinifolium was compared with water extract of Zanthoxylum schinifolium to test antimicrobial activities against Vibrio parahaemolyticus by disk method. Ethanol extract was more effective than water ,extract on the antimicrobial activities. It had remarkable antimicrobial activities against Vibrio parahaemolyticus. It was very stable on the wide range of temperature and pH. It turned out by GC-MS that estragole (4-allyl anisole) was a major antimicrobial component of Zanthoxylum schinifolium extract. These results indicated that Zanthoxylum schinifolium extract could protect against bacterial contamination and inhibit a growth of Vibrio parahaemolyticus.

The purpose of this study was to identify the major factors affecting performance in health promoting behavior. The subjects for this study were 414 workers employed in one transportation manufacturing plant in Pusan and were obtained by a convenience sample. Data were collected from November 11th to December 21th, 1996 by structured questionnaires. Collected data were analyzed by SPSS PC. The results of this study are as follows. 1. The average score of performance in the health promoting behavior was 2.42 ; the range of the score was from 1.44 to 3.71. The variable with the highest degree of performance was self-actualization, whereas the one with the lowest degree was exercise. 2. In the relationships between demographic variables and performance in the health promoting behavior, only the shift system showed statistically significant differences in the total of health promoting behavior ; especially the group of no shift operation was higher in the performance of subscale such as exercise, nutrition, interpersonal support than that of the shift operation. Some demographic variables showed significant differences in the subscale of the health promoting behavior ; age, worker's career and marital status. 3. Performance in the health promoting behavior was significantly correlated with perceived health status, health conception, self-efficacy, perceived benefits and perceived barriers. 4. The most important factor that affects performance in the health promoting behavior was self-efficacy. The combination of self-efficacy, perceived benefits, perceived health status, perceived barriers, shift system and department of work accounted for 31.05% of the variance in health promoting behavior.

Purpose: The purpose of this study was to examine the degrees of cellular phone usage among middle school students and to identify discriminating factors of addictive use of cellular phones among socio-demographic and psychological variables. Methods: From 123 middle schools in Busan, potential participants were identified through stratified random sampling and 747 middle school students participated in the study. The data was collected from December 1, 2004 to December 30, 2004. Descriptive and discriminant analyses were used. Results: Fifty seven percent of the participants were male and 89.7% used cellular phones at school. The participants were grouped into three groups depending on the levels of the cellular phone usage: addicted (n=117), dependent (n=418), non-addicted (n=212). Within the three groups, two functions were produced and only one function was significant, discriminating the addiction group from non-addiction group. Additional discriminant analysis with only two groups produced one function that classified 81.2% of the participants correctly into the two groups. Impulsiveness, anxiety, and stress were significant discriminating factors. Conclusion: Based on the findings of this study, developing intervention programs focusing on impulsiveness, anxiety and stress to reduce the possible addictive use of cellular phones is suggested.

It is important to recognize the pathognomonic cytologic findings of chordoma, because of overlapping cytologic features between chordoma, chondrshdosarcoma, myxofilbrillary ependymoma, and metastatic adenocarcinoma. We reviewed the cytomorphologic features of 5 cases of chordoma diagnosed by fine needle aspiration cytology at Korean Cancer Center Hospital from 1987 to 2003. Clinical and radiographic findings of each case were reviewed. Four males and one female (29-54 years) had tumors involving the sacrum. Pain was the presenting symptom in 4 cases. The three cases showed moderate to high cellularity. In all cases, typical physaliferous cells with or without cytoplasmic processes were noted. In two cases, the background was myxoid with single scattered cells. Cell clusters showing cord-like arrangement were occasionally seen. The single or clustered cells showed mild cellular pleomorphism with slightly increased nuclear/cytoplasmic ratio. Mitotic figures were not seen. In our review, the recognition of physaliferous cells is the most important feature to diagnose chordoma and to differentiate it from other lesions mimicking chordoma.

To investigate the association between hepatocellular carcinema(HCC) and infection of hepatitis B virus(HBV) and hepatitis C virus(HCV) in an HBV endemic area, a case-control study of 254 patients with HCC and of 1,270 age and sex matched health control subjects was done. Among the 254 HCC patients 166(65.4%) were positive for hepatitis B surface antigen(HBsAg), 49(19.3%) were positive for HCV antibody (anti-HCV Ab). The crude odd ratio of patients with HBsAg was 36.1(95% CI :22.4-58.2) and with anti-HCV Ab was 9.0(95% CI :5.5-14.6). In an analysis, which HBsAg(-), HBcAb(-), anti-HCV Ab(-) group was chosen as referent group, odd ratio of HBsAg(+) group was 14.4(95% CI: 7.2-28.9) and of anti- HCV Ab(+) was 10.7(95% CI: 2.9-40.0). odd ratio of anti-HCV Ab(+), HBsAg(+) group and anti-HCV Ab(+), HBsAg(-), HbcAb(+) group for HCC were elevated to 27.3(95% CI : 9.0-82.9), 15.9(95% CI:7.1-35.8) respectly, The odd ratio of anti-HCV Ab(-), HBsAg(-), HBcAb(+) group was 2.4(95% CI : 1.1-5.0). These result suggested that HBV and HCV were associated with HCC. In HBV endemic area patients with HBcAb alone should be considered risk group for HCC.

Objectives : To estimate mumps incidence during the study period and to evaluate the completeness of case reporting. Methods : Capture-recapture methods, originally developed for counting wildlife animals, were used. The data sources were 1) the National Notifiable Communicable Disease Reporting System (NNCDRS; 848 cases), 2) the School Health Reporting System, temporarily administered by the Division of Education (SHRS; 1,026 cases), and 3) a survey of students (785 cases). We estimated the number of unobserved mumps cases by matching the three data sources and fitting loglinear models to the data. We then determined the estimated total number of mumps cases by adding this to the number of observed cases. Completeness was defined as the proportion of observed cases from each source to the total of estimated cases. Results : The total number of observed cases was 1,844 and the total number of estimated cases was 1,935 (95%, CI: $1,878\sim2,070$). The overall completeness was 43.8% of the NNCDRS, 53.0% of the SHRS, and 40.6% of the survey. However, completeness varied by area and age. Conclusion : Although the completeness of NNCDRS data appeared higher than in the past, it is difficult to generalize this result In Korea, it is possible to estimate the size of health hazards relatively cheaply and quickly, by applying capture-recapture methods to various data using a multiple data collection system.

Purpose: This study investigated the prevalence of middle school students with ADHD and the level of middle school teacher's knowledge, coping strategies, and educational intervention for ADHD. Methods: There were 185 teachers and 6,381 middle school students at the 6 middle schools in Pusan. The data was collected from December 20, 2003 to January 10, 2004. Results: 195 middle school students had ADHD (3.1%). The male students with ADHD made up 4.4% of the total students and the female students with ADHD totaled 1.3%. The mean score of middle school teacher's knowledge about ADHD was 21.86 of the score total 32. The teachers used a negative coping style less than an active and passive coping style. Of the educational interventions, the environmental intervention in the classroom was used more than the educational intervention activity. 61.1% of the teachers responded that they did not know very much about ADHD. 93.5% of the teachers had no educational experience with ADHD. 94.1% felt that they needed an education program about ADHD and over half of them intended to participate in an ADHD education program. Conclusion: Based on the results of this study, we concluded that the middle school teachers felt that they had insufficient knowledge about ADHD. They wanted the opportunity to increase their knowledge of ADHD. Therefore, it is necessary for educational programs about ADHD for teachers to be developed and made available to them.

The study on leptospiral infection among cows was carried out to find out possible role of this domestic animal as an infection source for humans, and the magnitude of economic loss due to abortions caused by leptospiral infections among the domestic animal. Bood samples of 459 cows in May and 446 heads in November 1989 were collected from 19 villages of Kyunggi Province. These samples were cultured and serologically tested. Only one strain of leptospires, most strongly reactive to Pomona antibody, was isolated from duplicated cultures of 985 cow blood samples in EMJH medium. Serological test by MAT with seven reference strains and three locally isolated strains was positive in 12% of the sample in May and 26% in November ; positive rate increased slightly as the age of cows increased and male cows had higher positive rate, however, there was on difference in positive rate by type of cow and area. There was no statistically significant association between abortion history among cows(one yearperiod) and positive MAT. Thus it was concluded that the leptospiral infection of cows may play a role for human infection, and the leptospiral infection of cow may not be the major cause of abortion although further study is necessary for definite conclusion.
