Methods: We collated and reviewed previously conducted review studies on border closures during infectious disease outbreaks to derive relevant themes and factors. Results: According to our systematic review on border closures and travel restrictions, the effects of such containment efforts are limited. We suggest considering the following factors when determining whether to impose border closure measures: (1) disease characteristics, (2) timeliness of implementation, (3) transmission delay and the basic reproduction number, (4) globalization and pandemics, and (5) social and economic costs. Conclusions: Our assessment indicates that the effects of border closures are at best temporary and limited. Alternative measures must be contemplated and implemented to suppress the spread of COVID-19 in particular and infectious diseases more broadly.

This study investigated consumers` recognition on shelf life of health functional foods to set up their rational expiration date. For this study 107 male and female adults aged 20 to 59 years were randomly selected as major consumers of health functional foods. And their data were analyzed with SPSS 17.0. The questionnaire included questions asking a consumer`s recognition on the shelf life of health functional foods and how to treat health function food passing its shelf life. In this study, the consumers were found to pay attentions considerably to the shelf life. But most of them did not know an accurate meaning of the shelf life of health functional food and mistook it for expiry date. In addition, the consumers doubted safety of health functional foods passing the shelf life. Therefore, education for consumers about an accurate meaning of the shelf life was needed. The results of this study were considered to be helpful to set up a reasonable expiration date for health functional food.

Background and Purposes: Over the past three decades, numerous studies performed in Korea have reported that job stress is a determinant risk factor for chronic diseases and work disability. Every society has its own culture and occupational climate particular to their organizations, and hence experiences different occupational stress. An occupational stress measurement tool therefore needs to be developed to estimate it objectively. The purpose of this study is to develop and standardize the Korean Occupational Stress Scale (KOSS) which is considered to be unique and specific occupational stressors in Korean employees. Subjects and Methods: Data were obtained from the National Study for Development and Standardization of Occupational Stress (NSDSOS Project: 2002-2004). A total of 12,631 employees from a nationwide sample proportional to the Korean Standard Industrial Classification and the Korean Standard Occupational Classification were administered. The KOSS was developed for 2 years (2002-2004). In the first year, we collected 255 items from the most popular job stress measurement tools such as JCQ, ERI, NIOSH and OSI, and 44 items derived from the a qualitative study (depth interview). Forty-three items of KOSS, in the second year, were retained for use in the final version of the KOSS by using Delphi and factor analysis. Items were scored using conventional 1-2-3-4 Likert scores for the response categories. Results: We developed eight subscales by using factor analysis and validation process: physical environment (3 items), job demand (8 items), insufficient job control (5 items), interpersonal conflict (4 items), job insecurity (6 items), organizational system (7 items), lack of reward (6 items), and occupational climate (4 items). Together they explained 50.0% of total variance. Internal consistency alpha scores were ranged from 0.51 to 0.82. Twenty-four items of the short form of the KOSS (KOSS-SF) were also developed to estimate job stress in the work setting. Because the levels of the subscales of occupational stress were gender dependent, gender-specific standard norms for both the 43-item full version and the 24-item short form using a quartile for the subscales of KOSS were presented. Conclusion: The results of this study suggest that KOSS might be an appropriate measurement scale to estimate occupational stress of Korean employees. Further and more detailed study needs to be conducted to improve the validity of this scale.

본 연구는 다중역할을 수행하고 있는 중년 직장여성을 대상으로 일-가정 갈등, 사회적지지, 자기효능감, 삶의 의미 간의 관계를 파악하고자 하였다. 구체적으로 연구 대상자는 40세에서 60세 미만의 자녀가 있는 맞벌이 중년 직장여성들로서 총 202명의 자료가 최종 분석에 사용 되었다. 구조방정식 모형을 통해 자료를 분석하였는데, 분석결과 첫째, 중년 직장여성의 일-가정 갈등은 사회적지지, 자기효능감과 유의미한 관계를 맺고 있었으나, 삶의 의미와는 직접적인 유의미한 관계를 갖고 있지 않았다. 둘째, 사회적지지와 자기효능감은 일-가정 갈등과 삶의 의미 간의 관계에서 유의미한 완전매개효과를 보이는 것으로 나타났다. 따라서 중년 직장여성이 다중역할 수행에서 삶의 의미를 찾도록 도와주기 위해서는 사회적지지와 자기효능감을 높여줄 필요가 있다. 연구결과를 토대로 교육과 상담에의 논의점 및 제안점을 제시하였다. The purpose of our study was to identify a structural relationship between the work-family conflict, social support, self-effectiveness and the meaning of life among married female workers who are performing multiple roles. The subjects were middle-aged married working mothers aged 40 to 60, they taked care of at least one child and worked more 10 hours in a week. The 202 data were analyzed using a structural equation model. The analysis results showed in the lives of middle-aged married female workers as follows. First, the work-family conflict had direct effects on social support and self-effectiveness significantly. And the work-family conflict had no significant direct effect but significant indirect effect on the meaning of life. Second, social support and self-effectiveness had complete mediation effects in relation between the work-family conflict and the meaning of life. Therefore, to find the meaning of life for middle-aged married female workers, it is necessary to enhance their social support and self-effectiveness. Based on the results of the study, we suggested the discussion for education and counseling.

Background : The incidence of tetanus in adults and neonatal tetanus have been markedly reduced by world-wide use of DTP vaccines. But, tetanus is still one kind of major health problems in many developing countries, and several serosurvey stduies in developed ountries revealed that substantial proportions of adult opulation may lack immunity against tetanus and imunity level against tetanus is continuously decreasing by age. In Korea, tetanus outbreaks have been disappeared since the 1980s by high acceptant DTaP vaccination rates. Annually, few tetanus patient has been reported since 1990s. But, there knave been no seroepide-miological studies to tetanus, no trials to assess tetanuts immunizations. And we do not use Td vaccine in adults for maintaning tetanus immunity. In this aspect, we conducted age related survey of immunity to tetanus and indirectly assessed the immunogenecity of tetanus vaccines, used in Korea. Methods : For the evaluation of age related sero-survey of tetanus immunity in Korean population, study subjects were classified into 16 groups (A∼J group; below 10 years with one year interval, K∼O group; 11~60 yrs with 10 years interval, p group; over 60 yrs). The numbers of each group were 100, and sex distributions of each group were almostly equal. And far the indirect assessment of tetanus immunization in Korean children, children under 15 years old age were classified into 6 groups (I∼VI) according to the status of DTaP vaccination. The numbers of this each group were 50, and sex ratio was almostly equal. Specific IgG antibody to tetanus toxin were detected by ELISA. And the ANOVA repeated t-test was used to compare antibody levels in study groups. Results : In age related groups, the antibody levels to tetanus toxin were well maintained until 20 years old age group (L group), but thereafter the titers abruptly decreased below 0.1 IU/mL and over 75% populations among the groups over 30 years old age needed maintenance of protective immunity to tetanus. The antibody level of male was statistically higher than that of female in P group. In the groups related DTaP vaccination status, the antibody titer was very low in pre-vaccination group (I), but the titers after primary vaccinations were sharply increased and highly maintained until 15 years. Conclusion : The results of our study revealed that the immunity to tetanus was dramatically decreased in age groups over 30 years old. This result indicates that Td vaccination program in adults should be considered for maintenance of immunity to tetanus. And our study indicate that DtaP vaccination programs and vaccines, used in Korea, are effective for acquisition and maintenance of tetanus immunity in Korean children.

고목재의 치수안정성을 향상시키는 무수초산과 포름알데하이드 기상처리가 팔만대장경 경판의 주요 소재인 산벚나무의 중량, 흡습성, 그리고 재색에 미치는 효과를 야외폭로와 촉진열화시험을 통해 측정하였다. 무수초산과 포름알데하이드 72시간 기상처리에 의한 시편의 중량은 각각 평균 8.1과 15.7% 증가하였다. 두 달 이상 야외폭로된 아세틸화 시편의 중량은 1.5% 밖에 감소하지 않았으나 포름알데하이드 시편은 매우 많이 감소하였다. 또 아세틸화 처리는 시편의 흡습성을 낮추었으며 자외선에 의한 갈변을 방지하였으나, 포름알데하이드 처리는 그렇지 못하였다. 한편 포름알데하이드 처리시간이 긴 시편일수록 할열과 변형이 더 많이 발생하였다. 따라서 포름알데하이드 처리는 고목재 보존방법으로 맞지 않으나, 아세틸화 기상처리는 액상처리와 같이 중량을 과도하게 증가시키지 않으면서도 자외선과 비로 인한 재색변화와 중량감소를 막아줌으로 고목재의 보존처리에 적합하다고 할 수 있다. Small cherry specimens modified with acetic anhydride and formaldehyde vapor phase were weathered by outdoor exposure and accelerated conditioning in a climate chamber. The effects of the chemical modification were evaluated by measuring their weight percentage gains (WPG), hygroscopicity and color differences before and after weathering. The average WPGs of the 72 hour acetylated and formaldehyde-treated specimens were 8.1 and 15.7%, respectively. After outdoor exposure for more than 2 months, the acetylated specimens lost weights by only 1.5%, but the formaldehyde-treated did much more than the formers. It was revealed that acetylation reduced the hygroscopicity and discoloration of wood while formaldehyde treatment didn't. Moreover the longer is the formaldehyde treatment time the more degraded after weathering. It was concluded that the vapor-phase acetylation could be applied for improving the dimensional stability of old wooden blocks.

康鎭守 영남이공대학 2002 論文集 Vol.31 No.-

The debate of accrual basis and cash flow reporting is one of the most representatives in the accounting literature. In special, many empirical studies argue that cash flow information has the additional predictive ability in predicting business failure. Accordingly, this study is to test the predictive ability of business failure by cash flow information. In order to achieve the purpose, two hypotheses are tested by multiple discriminant analysis and laboratory experiment. method Eighty two samples were selected in the unlisted firms from 1990-1994. Forty one failure companies of them were matched by Fourty one non-failure companies. The contribution of this paper is to test the unlisted companies' prediction of bankruptcy The results of the study are as follows; 1. The model that includes a cash flow information has superior predictive ability to the model that cash flow information is excluded. 2. The combined model that includes cash flow and financial ratios has better discriminant ability than the seperate models;one using the financial ratios and one using cash flow ratios.

There have been so many researches about problems of cigarettes and relation of smoking and heath since 1950's and generally known that smoking is one of the worst factor of increasing disease and mortality. No matter what such many proofs about various problems of smoking have been researched, smoking rate of current male collage students has not been decreased. Besides, most of the researches about cigarette use and its addiction have been focused on the adolescent or adult women smokers or adult male, not male collage student. Therefore, the subject of this study is about smoking attitude and smoking behavior of male collage students by general features. Smoking attitude was analyzed by modifying 'Guidelines for the content of tobacco smoking surveys of the general population'(WHO, 1982). Two hundred of male collage students participated to the distributed questionnaire for one week in May. The smoking attitude was categorized into duration of smoking and number of cigarette per day(CPD), and nicotine dependency, investigated by Fagerstrom Tolerance Questionnaire(FTQ) (Fagerstorm & Schneider, 1989). All statistics were performed by procedure of SAS according to number, percentage, mean, standard deviation, and ANOVA. The results are as follows: 1. Smoking attitude level was mean 25.73±5.15 marks, ranging from 13 to 39 marks of the total 40 marks. 2. Duration of cigarettes, number of cigarette per day, and nicotine dependency were mean 5.14±2.84 years, 12.88±6.85 pieces, and 4.78±1.69, respectively. 3. Smoking attitude showed significance according to general features such as marital state and allowance, but the significance according to marital state is not valuable because the numerical difference is so big between married one and single that they cannot be compared with each other. 4. Duration of smoking was significant according to general features such as age and allowance. 5. Smoking amount showed significance the factors of age only. 6. ll1ere was no significance in nicotine dependency according to general features. As a result, smoking attitude of male collage student in this study shows moderate level. Smoking attitude and duration is significant according to allowance, and smoking amount is significant according to age. Nicotine dependency according to general features is not significant but comparing with the preceding study about adult male, male collage students in this study are respectively more nicotine-dependent than adult male smokers. In conclusion, the right allowance usage strategies and effective heath education focused on the young are needed. In addition, helpful programs and information spreading strategies are necessary for establishing higher level of smoking attitude. At last, systemic regulations in daily living for ""anti-nico-dependent"" and perspective reforming of male university student are needed for reducing nicotine dependency.
