Creatine and 3.4-Dimethylhippuric acid (3,4-DMHA), a glycine conjugate of 1.2,4-trimethylbenzene (1,2,4-TMB) were determined in the urine of workers exposed to 1,2,4-TMB vapor. The best condition for the simultaneous determination of 3.4-DMHA and creatine by high performance liquid chromatography was obtained by reverse phase C18 column (4.6X150mm, 5mcm) as stationary phase and 20% acetonitrile in 20mM phosphate buffer (pH 3.0) containing 4mM sodium octylsulfate(SOS)as mobile phase. The recovery of 3,4-DMHA spiked to blank urine in the range of 1~5mcg/ml was about 96%. The concentration of urinary 3,4-DMHA of workers had a positive correlation with the environmental level of 1,2.4-TMB (r=0.866). The data suggest that urinary 3,4-DMHA concentration is a useful biological index for 1,2.4-TMB exposure.

The purpose of this study was to make the basic data for the managing and improving the nurse's performance appraisal, and also to get the useful data for changing to the future development-oriented performance appraisal and making the plans for the effective and comprehensive personnel organization in the general hospital's nurse organization. The data were collected by self-rating questionnaires to total 513 nurses, which consisted of 36 appraiser of head nurses and 477 nurses of employee, from March 10 to March 30, 2003. The study questionnaire was made by total 35 items in which 6 items about the general characteristics of the involving nurses, and 21 items for the management and 8 items for the improvement of the performance appraisal that originally developed by Young-Hee Kwon(1999) and partially modified and added by author. Statistical analysis was performed using SPSS/PC+ program(Version 10.0); frequency, percentage, mean and standard deviation, t-test, and x2-test were calculated. A P value of 0.05 or less was considered significant. The results were as follows: 1. Realities of the Management System on the Nurse's Performance Appraisal in Target Hospital Most of subjects understood the important object of performance appraisal as the basic data for the promotion to better position in the hospital. The degree of satisfaction about the results of performance appraisal as for the agreement and fairness was significantly higher in appraisors than employees. For the management of the performance appraisal, the education or training was insufficient in appraisors, the method of data collection was direct, indirect observation way and the most frequent rate of necessary time for evaluation was under 10 minutes, and the most frequent error of performance appraisal was appeared in the years of work. The lack of understanding for the items, frequency and opportunity of the performance appraisal was presented in employees. Also, the information about the performance appraisal from the department of nurse was lacked and the interview with head nurse during the evaluation was insufficient in employees. 2. Ideas for The Improvement of System of The Performance Appraisal The most high frequency opinion about the useful application of the performance appraisal results was that it should be used as a basic data for the promotion of position and self-development of the abilities in appraisors, and used for self-development of abilities and motivation of individuals in employees. The ideal method of performance appraisal was responded as that head nurses and their colleague should be reevaluated by chief of department of nurse in appraisors, while the data from head nurse and colleague should be added up by chief administrator in employees. The adequate frequency of evaluation was responded as 2 times a year in both groups. As for providing the information before evaluation, the rate of agreement was high in both groups. The method of interview by individual contact was responded similarly as necessary or unnecessary in appraisors, while responded as necessary in employees. As the results of this study, the problems of current system of the performance appraisal were: first, the lack of education and training about the performance appraisal; second, the lack of providing information previously to employees and lack of way of participation into the evaluation by employees; third, lack of mutual understanding of the system of performance appraisal by both appraisors and employees. For the improvement of above problems, the author suggested that it should make the more effective system of performance appraisal by education and training of appraisors, increasing the interpersonal understanding between appraisors and employees by showing the results of evaluation, and increasing motivation to improve and develop the nurse's abilities of duty performance.

Objective: To investigate the serial CT findings of Paragonimus westermani infected dogs and the microscopic structures of the worm cysts using Micro-CT. Materials and Methods: This study was approved by the committee on animal research at our institution. Fifteen dogs infected with P. westermani underwent serial contrast-enhanced CT scans at pre-infection, after 10 days of infection, and monthly thereafter until six months for determining the radiologic-pathologic correlation. Three dogs (one dog each time) were sacrificed at 1, 3 and 6 months, respectively. After fixation of the lungs, both multi-detector CT and Micro-CT were performed for examining the worm cysts. Results: The initial findings were pleural effusion and/or subpleural groundglass opacities or linear opacities at day 10. At day 30, subpleural and peribronchial nodules appeared with hydropneumothorax and abdominal or chest wall air bubbles. Cavitary change and bronchial dilatation began to be seen on CT scan at day 30 and this was mostly seen together with mediastinal lymphadenopathy at day 60. Thereafter, subpleural ground-glass opacities and nodules with or without cavitary changes were persistently observed until day 180. After cavitary change of the nodules, the migratory features of the subpleural or peribronchial nodules were seen on all the serial CT scans. Micro-CT showed that the cyst wall contained dilated interconnected tubular structures, which had communications with the cavity and the adjacent distal bronchus. Conclusion: The CT findings of paragonimiasis depend on the migratory stage of the worms. The worm cyst can have numerous interconnected tubular channels within its own wall and these channels have connections with the cavity and the adjacent distal bronchus.

이성현,임정묵,이세원,장태후,박정희,서영석,이정호,Kamala-Kannan Seralathan,오병택 한국식품과학회 2023 Food Science and Biotechnology Vol.32 No.9

The limited yield of Ulmus davidiana var. japonica root bark (URB) extract is considered an economic loss to the food industry. Improving extraction yield and bioactivity through fermentation increase the industrial usage of URB. The study aims to optimize the fermentation with cellulolytic and pectinolytic bacteria and evaluate the bioactivity and anti-Helicobacter pylori activity of the fermented URB extract. URB fermentation with the Bacillus licheniformis FLa3, isolated from salted seafood (Sardinella zunasi), under optimal conditions (37 °C, pH 6, 10% inoculum dose, and 36 h) improved the extraction yield by 36% compared to the control. The antioxidant and antimicrobial activity of the fermented extract were significantly higher than non-fermented extract. High-performance liquid chromatography results confirmed that the fermentation increased the proportion of bioactive components such as catechin (171.7%), epicatechin (144.3%), quercetin (27.3%), and kaempferol (16.7%). The results confirmed that the fermentation increased both the extraction yield and bioactivity.

본 연구는 고령 경비원의 근로환경 특성에 대해 분석하고 근로환경이 우울에 미치는영향을 살펴보고자 하였다. 이를 위해 ‘2020년 노인실태조사’를 활용하여 ‘경비⋅수위⋅ 시설관리’ 직종에 근무하는 65세 이상 노인 317명을 분석대상으로 선정하였다. SPSS 26.0 프로그램을 사용하여 기술통계와 빈도분석, t-검정과 One-way ANOVA, 상관관계 분석, 다중회귀분석을 진행하였다. 연구의 주요 결과는 다음과 같다. 근로환경 특성에 따라우울 수준에 차이가 있는지를 살펴본 결과, 상용직이 임시·일용직보다, 주당 근로시간은 40시간 이하일 때가 그 이상일 때보다, 일터에서 경험한 차별 경험이 있을 때가 없을 때보다 높은 우울 수준을 경험하는 것으로 나타났다. 근로환경 특성이 우울에 미치는 영향을 분석한 결과, 사업체에 소속되어 있을수록, 주당근로시간이 적을수록, 일터에서 연령차별을 경험할수록, 근무 만족도가 낮을수록 우울 수준이 높은 것으로 검증되었다. 본 연구 결과를 통해 고령 경비원의 건강한 근로환경 개선과 우울 문제의 예방 및해결 전략 마련을 위한 사회복지 실천적, 정책적 대안을 제시하였다. This study aimed to identify the work environment characteristics of older security guards and explore their association with depressive symptoms. This study was conducted with a sample of 317 older adults aged 65 or above working in the “security, guard, and facility management” field using the ‘2020 Survey on older adults’. To analyze the data, descriptive analysis, frequency analysis, t-tests, one-way ANOVA, correlation analysis, and multiple regression were conducted using SPSS 26.0. The main findings of the study are as follows. It was found that regular workers showed higher levels of depressive symptoms compared to temporary or day workers, workers who worked less than 40 hours per week experienced higher levels of depressive symptoms than those who worked more than 40 hours per week, and workers who experienced discrimination at work experienced higher levels of depressive symptoms than those who did not. Moreover, It was found that the more the older security guards belonged to business organizations, worked fewer hours per week, experienced age discrimination in the workplace, and had lower job satisfaction, the higher the level of depressive symptoms. Based on these results, this study suggested practical and political interventions to improve the work environment and prevent the depressive symptoms of older security guards.

The purpose of this study is to investigate students' conceptions on the rock and the difference of conceptions by sex and also to provide the basis of effective learning strategies to correct their misconception. For this study, 48 students were selected from 6th grade of one elementary school in Busan. Data were obtained by questionnaire which is consisted of ten questions on rocks. The results of this study were as follows : 1. Girls were better than boys in the conception about formation of soil. 2. Students didn't have a correct basis of sedimentary rock to be formed. 3. More than 50% students had wrong conception about deposition order. 4. Girls had wrong conception about the formation cause of a metamorphic rock and boys had wrong conception about gneiss. 5. Student' preconception didn't easily change the conceptions to rock cycle. 6. It was found that students had the varied preconceptions on rock and expressed as empirical and visual view rather than scientific expression of the concepts. They had also misconceptions about composition and rock cycle. 7. For sex, girls and boys had similar scientific conceptions. Academically high and middle ranking group had scientific conceptions about rock. 8. Remedial methods such as the observational learning and utilization of audio-visual materials, field trips and visitation of the science facilities will be necessary for students to correct misconceptions.
