Korea paid attention to the work injury insurance in the early economic development stage as other developed countries did. Thus "The industrial Accident Compensation Insurance Law" was legislated in 1963 and it is now expanded to apply to the workplace with five or more employees. Beside the low coverage of the number of employees, the scope of benefits are the problem of work injury insurance. The work injury insurance's main benefits are for the loss of income and the medical cost caused by occupational accidents. On the other hand, the investment on the prevention accident and the medical, social and employment rehabilitation is very low, even though the occupational accident pension is higher than that in other OECD countries. Practically lay-off benefits and survivor' benefit for some special workers are paid more than they need, therefore they want to remain under the benefit condition and the medical care days are longer. This paper indicates the problems of work injury insurance and suggest how to improve the functions of it.

In this study, we propose methods for. the efficient management and integrity of groundwater in response to a diminishing supply. As an alternative water resource for the future. we investigated and comparatively analyzed the quality standards of groundwater in the US (New York, Wisconsin and Texas), Austria, Netherlands, Canada, Japan and United Kingdom. These developed countries heavily depend on groundwater, more than 70%, for drinking water and apply those drinking water standards to groundwater quality. However, there exists few differences in the quality standards of groundwater among the countries, because each country possesses its own individual environment and management. In Korea, surface water pollution is getting serious and its water resources are diminishing. Therefore we propose several new quality criteria that many countries regulate at these days for their efficient management of groundwater. There is a need to divide BTEX criterion into Benzene, Toluene, Ethylbenzene and Xylene, individually. In. addition, it is needed to establish BTEX criteria into agricultural water and industrial water use standards as well as daily life use standards. Also, regulations for some PAHs, showing carcinogenicity, are required. Due to rapid industrialization various hazardous chemicals were utilized and their uses are increasing each year. Therefore, there is a strong need to introduce n~w standards and tighter regulations of the levels. At the same time, the criterion of nitrogenous compounds need' to be regulated individually in order to prevent the damage incurred by the compounds. Several developed countries have established standards for radon, previously caused environmental accidents in Korea. Therefore, we propose the necessity of groundwater quality standards for radon in this study.

Natech risk is a type of complex disasters that natural hazards trigger technological disaster or industrial accidents. Research on Natech risk has been started from the mid-1990s in European countries and the Unites States, and drawn much more attention after the Fukushima nuclear accident caused by the 2011 East Japan earthquake. While early studies on Natech risk have focused on the causal natural hazards and possibility to occur, and the resulting spill of hazardous materials from the perspective of science and engineering, the recent research interests lie on effective Natech risk management. Especially, emphasizing the difference of Natech risk management from traditional disaster management, issues of uncertainty management, integration between natural disaster and technological disaster, and responsibility, has been drawn attention. In Korea, Natech risk has not been introduced as a research topic. Although some regulatory improvements have been made in nuclear safety and chemical Substance management after the Fukushima disaster, the potential impact of natural hazards in these areas has not been considered yet. It is necessary to raise the issues of Natech risk management in research and policy areas through active discussion and interdisciplinary approaches.

As the society turns into more of an information an technology centric society, the importance of information security is being increased these days. Recently, as the number of leaking accidents of personal information and valuable industrial technology is on the rise, every field of industry endeavors to come up with a security solution. In particular, since defense industry is a field where it establishes national defense power that is essential of national security, it requires higher standards of security solutions than any other ordinary fields of industry. According to Defense Industry Security Work Instructions, defense industry firms from security organizations and employ a security worker corresponding to the firm's scale and conditions. In an environment where essential information and technology are stored and managed in information and communication system or storing media, the duty and role of IT security workers are crucial. However, there is a shortage of systematic analysis on the work of IT security workers and development of curriculum to enhance their professionalism. Thus DACUM process, a job analysis technique, was used to identify IT Security workers' duties and responsibilities and verify the validity and credibility of the deducted results from the survey. The findings of this study will help in development of IT security duty in defense industry and can be used as baseline data for the development of curriculum and amendments of related regulations.

The purpose of this study was to investigate the vocational identity through the reflection of the major experience as the teacher through the life history of the technical high school. In order to achieve the purpose of this study, two technical high school mechanical and career teachers were selected as research participants and in-depth interviews were conducted with them. The data obtained through the in-depth interviews were analyzed through six steps. Six major experiences of the participants were identified as results of the research: (1) the experience of trying to train the specialist of precision machining in the beginning of teacher's life, (2) experience as a skill competition team teacher, (3) experience of innovating public education by introducing new industry field, (4) experience of constant learning new field and sharing with colleagues, (5) experience in the rapid change of the status of technical high school, (6) experience in the prevention of students' safety accidents and maintenance of the practice field. Through these educational experiences, each research participant was forming one's vocational identity as a mechanical teacher. The vocational identity of the research participants were identified as follows: (1) identity drifting phase, (2) identity stability stage, (3) transition stage of the teacher role, (4) suspended stage to preserve identity, (5) identification sublimation stage, (6) identification of the true meaning of the teacher, and integration of the identity. Through these six steps, their identities were formed, strengthened and changed at each stage.

The Bhopal gas tragedy involving methyl isocyanate (MIC) is one of the most horrific industrial accidents in recent decades. We investigated the genotoxic effects of MIC in long-term survivors and their offspring born after the 1984 occurrence. There are a few cytogenetic reports showing genetic damage in the MIC-exposed survivors, but there is no information about the associated cancer risk. The same is true about offspring. For the first time, we here assessed the micronucleus (MN) frequency using cytokinesis-blocked micronucleus (CBMN) assay to predict cancer risk in the MIC-affected population of Bhopal. A total of 92 healthy volunteers (46 MIC-affected and 46 controls) from Bhopal and various regions of India were studied taking gender and age into consideration. Binucleated lymphocytes with micronuclei (BNMN), total number of micronuclei in lymphocytes (MNL), and nuclear division index (NDI) frequencies and their relationship to age, gender and several lifestyle variabilities (smoking, alcohol consumption and tobacco-chewing) were investigated. Our observations showed relatively higher BNMN and MNL (P<0.05) in the MIC-affected than in the controls. Exposed females (EF) exhibited significantly higher BNMN and MNL (P<0.01) than their unexposed counterparts. Similarly, female offspring of the exposed (FOE) also suffered higher BNMN and MNL (P<0.05) than in controls. A significant reduction in NDI (P<0.05) was found only in EF. The affected group of non-smokers and non-alcoholics featured a higher frequency of BNMN and MNL than the control group of non-smokers and non-alcoholics (P<0.01). Similarly, the affected group of tobacco chewers showed significantly higher BNMN and MNL (P<0.001) than the non-chewers. Amongst the affected, smoking and alcohol consumption were not associated with statistically significant differences in BNMN, MNL and NDI. Nevertheless, tobacco-chewing had a preponderant effect with respect to MNL. A reasonable correlation between MNL and lifestyle habits (smoking, alcohol consumption and tobacco-chewing) was observed only in the controls. Our results suggest that EF and FOE are more susceptible to cancer development, as compared to EM and MOE. The genotoxic outcome detected in FOE reflects their parental exposure to MIC. Briefly, the observed cytogenetic damage to the MIC-affected could contribute to cancer risk, especially in the EF and FOE.

Purpose - The purpose of this research is reflected on the rapid development of online tourism industries. The study was to establish the strategy for Korean tourism enterprises to develop tourist commodities suitable for Chinese tourists and attract them to visit Korea by the empirical analysis of the relation between repurchase intention of tourists and its premise variables (e-service quality, perceived value and satisfaction). Research design, data, and methodology - This research carried out a questionnaire survey on Chinese tourists who visited Korea with experience of using the online travel agency web sites. A total 398 answers were recovered, 41 of them were excluded due to the dishonest answers and 357 of them were finally analyzed. The data was analyzed with IBM SPSS AMOS 22.0. Results - The research results show that in the online travel agency web site e-service quality, convenience, interactivity, information validity, credibility had a positive impacts on perceived value and satisfaction. The perceived value of online travel agency website users has positive impart on satisfaction and repurchase intention. Satisfaction of online travel agency web site users have positive impacts on repurchase intention. But safety has no impact on perceived value while positive impacts on satisfaction was affected. Conclusions - First, in the online travel agency web site e-service quality, safety has no impact on perceived value while it was shown to have positive impacts on satisfaction because the users of online travel agency web sites believe that the protection of personal information, the defense of cracker and the safeguard of payment security are the basic premises of website operation. Although safety does not have impacts on perceived value, users benefits will suffer damage when hacker intrusion and other accidents occur so that online travel agency web sites should not ignore the security concerns. Second, credibility is a major concern for online travel agency web site users. At this time, it is necessary for the web site to establish a system to display both the commodity information and the using experience published on the user's SNS, thus improving the credibility of the website information.

Various leaching tests were applied to the soil affected by accidental leakage of HF in an industrial area in Korea. Three different leaching methods including pH-stat, continuous batch leaching, and column tests were adopted to assess leaching characteristics and mobility of fluorine(F) in soil and the potential risks to ecosystem. Both natural and spiked samples were used for the leaching tests. F concentrations in the batch tests increased by leaching rapidly in the early stage of leaching and then maintained rather constant levels. Column leaching test also show similar result to that of the batch test. pH also controlled the leaching behavior of the soil. With increasing pH, more F was released in the pH-stat test. This is mainly due to the competition and exchange with hydroxyl ions, as pH increase to the alkaline range. Most of the F released by the accident seem to have removed in the very early stage of leaching, whereas some natural proportion from soil minerals are thought to have been released very slowly. Therefore, little F released during the accident remained, based on the results of this study on the samples after two years of the accident. We could conclude that soil contaminated by external effects such as chemical accidents should be managed immediately, especially with F.

Anjunshinmungo (The safety e-report) has been in operation since 2014, and there are about 1 million cumulative reports by June 2019. This study analyzes the contents of more than 1 million safety newspapers reported at the present time of information age to determine how powerful and meaningful the people's voice and interest are. In particular, we are interested in forecasting ability. We wanted to check whether the report of the safety newspaper was related to possible disasters. To this end, the researchers received data reported in the safety newspaper as text and analyzed it by natural language analysis methodology. Based on this, the newspaper articles during the analysis of the safety newspaper were analyzed, and the correlation between the contents of the newspaper and the newspaper was analyzed. As a result, accidents occurred within a few months as the number of reports related to response and confirmation increased, and analyzing the contents of safety reports previously reported on social instability can be used to predict future disasters.

In order to anticipate disease pattern and health problems of Koreans in the 1st part of 21st century (by the year 2020), transition of population characteristics, mortality and morbidity data during the last 30 years Koreans have experienced were reviewed. On the actual basis of epidemiologic transition process that has undergone during last 30 years since 1960 along with socioeconomic development and successful implementation of selective national health policies (family planning, medical insurance and etc.), following changes can be expected in the 21st century in Korea, under the assumption that the current rate of progress is maintained. The population of South Korea alone will be doubled the population of 1960 by the year 2013 : aged Population older than 65 years will be increased from 3.3% in 1960 to 11.4% in 2020 with increased average age of the population from 23.6 year in 1970 to 39.2 year in 2020; urban population from 28% in 1960 to 83% in 2005. GNP/capita has increased tremendously from U.S. $120 in 1970 to $6,749 in 1992, and the government estimated it would be 519,350 in 2010 and $29,460 in 2020. Growth and developmental indices of children, educational achievement and social status of women also showed a remarkable improvement and anticipated to make futher progress. Leading causes of mortality and morbidity have shown a striking change during the last 30 years, from infectious diseases to chronic degenerative diseases and man-made injuries. Occurrence of communicable diseases may become minimal although viral hepatitis, venereal diseases Including AIDS, and well adapted herpes virus infections will maintain their endemic level. Newly evolving infectious agents, however, should be carefully monitored because of rapidly changing environments and human behaviours. Tuberculosis may increase up to the epidemic level when AIDS prevails. Ischemic heart diseases may increase steadily with increasing occurrence of hypertension and diabetes mellitus whereas cerebrovascular diseases may be decreased slowly. Musculaskeletal diseases which contribute a lot to the disability of aged people may be a major health problems due to increased aged population. Mental diseases, particularly that caused by alcohol and drug abuse, and senile dementia may become a prominent health problem. On the other hand injuries caused by traffic and industrial accidents that have shown most striking increase till now may be decreased considerably by intensive intervention. The health policies in the 21st century will be oriented to the health promotion for good quality life rather than life-savings.
