Tritium. a radioisotope of hydrogen, is a constituent of water molecules and, therefore. is a ideal water tracer in hydrology. The tritium level of the precipitation in Korea has been monitored at the Pohang station from 1961 to 1976 by IAEA and has been analyzed from 1987 to present by KAERI. The tritium contents of the precipitation were recorded up to about 1,940 TU owing to world-wide nuclear testing in 1963. The contents have decreased and in present are about 10 TU. of which values are similar to those in pre-thermonuclear period. These data can be usefully applied to hydrological studies such as interpretation of relationship between groundwater and surface water and dating of groundwater.

Using matching and difference-in-differences estimation method, this study estimates causal effects of health shocks on employment and income of full-time workers aged 40-55. Acute hospital admissions lower significantly the employment probability and earnings. The changes in employment and earnings persist up to three years after the health shock. The economic impacts of health shocks vary by socioeconomic status and job characteristics among individuals. Irregular workers are more likely to leave their jobs after health shocks than regular workers. Among irregular workers, the probability of leaving labor market after health shock decreases with the size of the firm.

This paper investigates the relationship between the occupational gender wage gap and the proportion of high wage earning female workers in Korea. The main idea is that an increase in the number of high wage earning female workers in the workplace could lead to a decrease in the gender wage gap by eradicating the prejudice or reducing the statistical discrimination on female workers. We constructed a panel dataset by using the raw data from the Korean Survey Report on Labor Conditions by Employment between 2009 and 2016. The result shows that greater presences of high wage earning female workers in male dominant occupations have statistically significant negative impacts on residual gender earning dispersion.

The effects of microwave treatment on the perservation of foods, such as a seaweed soup and sea stoned radish shreds, were studied. Microwave treatment of microbial cell suspensions revealed that viable cells decreased dramatically when heated to 6$0^{\circ}C$. However, it was unlikely that microwave treatment to 60 is enough to decrease the viable cell counts efficiently in a seaweed soup and radish shreds. It was thought that microwave heating to at least 7$0^{\circ}C$ as a final temperature was an important factor to reduce microbial cell counts in foods. When foods were heated to 7$0^{\circ}C$ with a repetitive 15 sec "on" followed by 30 sec "off", no big differences were observed in viable counts during storage at 2$0^{\circ}C$ for 3 days, as compared to those treated with a full power. The microwave treatment with three stages was designed to solve problems associated with variations depending on food volumes and difficulties of heat diffusion in a solid food to be irradiated with a microwave oven. The three stage method was found to have a similar efficiency in the reduction of viable cell counts in foods to microwave treatment at a full power and to conventional methods, such as water bath heating or boiling for 3 min with a gas range.in with a gas range.

In the current study, the effects of living-alone older adults' social participation on their depressive symptoms were assessed. Data of 924 older adults from the Aging Research Panel Survey were analyzed. The results show that the effects of older adults' social participation on depressive symptoms vary depending on the types of social participation and gender. Men attending school or hometown alumni meetings and clan gatherings showed fewer depressive symptoms; women participating in informal social gatherings or organizations for leisure, culture, and sports had fewer depressive symptoms. The results suggest that living-alone older adults' gender and dimensions of social participation should be considered when designing programs and services to reduce their depressive symptoms.

Objectives: This study was designed to evaluate whether employment status is associated with the experience of unmet care needs. Methods: This study utilized the Korea Health Panel data from 2012 to 2016. A total of 4,083 workers were selected as baseline subjects in 2012 and were followed for four years. This study used the GLIMMIX procedure under the marginal model while adjusting for covariates. Results: A total of 12.4% of 4,083 people said they had failed at least once to have a treatment or checkup despite the needs. Those more likely to experience unmet care needs were women and people of lower income level, with worse health conditions and chronic disease. Precarious workers, the self-employed, and the unemployed were more likely to experience unmet care needs caused by economic burden than permanent workers (Odds Ratio: 2.14, 2.07, 2.74, respectively). Conclusions: This disparity means that precarious workers and the unemployed are more likely to face barriers in obtaining needed health services. Given their insecure employment status, meeting their needs for health care is an important consideration.

The purpose of this study is to identify the effects of employment insecurity on organizational commitment and turnover intention, and mediating roles of conflict in Chinese enterprise workers. We examined the theoretical background and conducted an empirical study. The statistical analysis results revealed the following. First, employment insecurity has significant negative effects on organizational commitment and positive effects on turnover intention. Second, employment insecurity has significant positive effects on task and relationship conflicts. Third, task and relationship conflicts have positive significant effects on turnover intention. Fourth, intragroup conflicts (task and relationship conflicts) have partial mediating effects between employment insecurity and organizational commitment, and turnover intention, but task conflicts have no mediating effects between employment insecurity and organizational commitment. On the basis of the research findings, this paper discusses the theoretical and empirical implications of the research, and provides directions for future research.

This study aims to examine attitudes of Korean workers towards foreign workers and predictors of their attitudes. The data for this study come from a survey conducted among 500 Korean workers employed at the companies which also hire foreign workers in Gyeonggi and Incheon areas. The findings reveal that a little more than half of Korean workers agree to give foreign workers the same labor rights as Korean workers and to allow them to bring their family members into Korea while a little less than half of them do not agree to grant residentship or citizenship to foreign workers. Attitudes towards foreign workers tend to be favorable with increase in perception of multiculturalism, period of working experience with foreign workers and education, and with decrease in feeling of threat from foreign workers.

이 논문은 근대 민족국가 형성과 민족 공용어의 창출의 상관성을 염두에 두고 식민지기 버마에서 버마어가 어떠한 정치적, 사회적 환경 하에서 어떻게 공용어의 지위를 획득해나갔는지에 대해 주로 버마어 산문의 대중화라는 각도에서 분석한 것이다. 베네딕트 앤더슨의 연구가 시사하는 것처럼 근대적 인쇄매체의 출현과 더불어 근대 버마어의 등장 및 대중화는 버마의 근대적 민족 형성에 큰 영향을 미쳤다. 제1차 영국-버마 전쟁 종결 후, 정치, 사회, 경제적 상황 변화와 함께 인쇄산업의 발달과 더불어 버마어는 대중매체에서 공용어로서의 지위를 획득해갔다. 식민시기에 버마 내 여러 지역에 어학원이 설립되었고 버마인이 어학교육 담당자로 고용되었다. 1930년대 초반에 근대 버마어 산문이 많은 저자들에 의해 집필되었으며, 1930년대 후반에 들어서서 독자들 사이에서 널리 읽히는 호황을 누렸다. 일본군 점령 후에는 일본군 당국의 허가 하에 버마어는 제2차 세계대전 중에 공식적 언어로서 인정되었다. 이러한 바탕 위에 근대 버마어는 1947년 헌법에 버마의 공식 언어로 명기되었다. 이러한 과정에 대한 분석을 통해 이 논문에서는 버마어가 식민지기에 표준어로서의 지위를 획득하고 그 버마어로 작성된 근대 버마어 산문의 사용이 버마의 민족 형성과정에서 결정적인 역할을 하였다는 점을 부각시켰다.

Purpose -The purpose of this study is to analyze how the accreditation system affect the selection of business strategies in social enterprises, which create social value rather than maximize profits. Design/methodology/approach - This study collected survey data from 40 accredited and 53 non-accredited social enterprises. This research employs a Fuzzy-set/qualitative comparative analysis to compare the combinations of factors that affect a social enterprise's performance Findings - The results show that for accredited enterprises organizational capabilities are significantly more important than networking capabilities, whereas for non-accredited enterprises internal communication, governance capacities and networking competencies are most important capabilities to improving their social performance. And also The accreditation systems for social enterprises would entice social enterprise away from business strategies based on with local society, which is differentiated with commonly accepted social enterprise model. Research implications or Originality - This research suggests that the accreditation system for social enterprises should be redesigned for enticing social enterprises in Korea to be more localized to meet local needs in terms of positive changes of local society.
