This study aims to identify issues with regard to practicing the current Korean Archives Law and, by doing so, to boost a community-wide discussion for revising it. Five researchers collaboratively interviewed five groups of stake-holders. Each group was consisted of practitioners in central government agencies, provincial governments, and educational district offices, as well as instructors of archival education programs. To uncover diverse issues from various perspectives, the interview was initiated by a common question: "Do you have any idea in terms of revising the current law?" After all interview sessions were completed, the researchers discussed among themselves and established a framework for analysis. The study is expected to provide a starting point for the Korean archival community to reinvent the law so that the archival culture and practice in Korea could open a new era.

Governments and companies are trying to reduce occupational accidents in the construction industry; however, the number of disasters are not decreasing significantly. This study aims to identify the correlation between factors affecting construction disasters quantitatively. To this end, 1,197 cases of serious disasters provided by Korea Occupational Safety and Health Administration (KOSHA) were analyzed using affinity analysis, one of the data mining techniques. The data from KOSHA were preprocessed and analyzed with variables of accident type, project type, activity type, original cause materials, sensory temperature, time of the accident, and fall height, and the association rules were derived for fall accidents and the others. For fall accidents, 64 association rules with lift ratios of 1.38 or greater were derived, and for the other accidents, 59 association rules with lift ratios of 1.54 or greater were derived. After analyzing the derived association rules focusing on the relationship among accident factors, this study presented the significance of applying the affinity analysis to address the study's limitations. The significance of this study can be found in that the correlation among factors affecting construction accidents is presented quantitatively.

Due to the change in the demographic structure, the problem of low birth rate and aging population leads to a serious decrease in human resources, and the necessity of introducing foreign workers is increasing. This study believes that the introduction of foreign workforce is the most effective to expand the working-age population in the era of low birthrate and aging, when demographic changes begin in earnest, and to this end, it sought to devise measures to improve the legal system for migrant workers. As a result of this study, first, the legal system for migrant workers should be unified and improved. It is necessary to establish or unify management agencies so that the 「Immigration Control Act」 and the 「Labor Act」 can establish a cooperative relationship. Second, the 「Immigration Control Act」 should be revised to make it easier for migrant workers to find employment. It is necessary to positively review the employment permit system and acquisition of nationality. Third, there should be no equity or discrimination against migrant workers. Under the principle of mutual benefit, employers and migrant workers should not be equally discriminated against. Fourth, the social insurance system must be added to the legal system of migrant workers. Therefore, the legal system should be reorganized so that migrant workers are not discriminated against in various insurance systems including the four major social insurance systems. In conclusion, the problem of low birthrate and aging population has become a serious social problem due to changes in the demographic structure, and the decrease in the possible generation population has reached a level of concern. The importance of migrant workers' employment and work environment is increasing. Nevertheless, related legal and institutional problems still exist, and measures to improve the legal system for migrant workers are needed.

Objectives : To identify the relationship between somatization, stress, depression, anxiety, and psychological symptoms risk for nurses working in the intensive care unit. Create clinical evidence of psychosomatic medicine research and complement the meaning of somatization. Methods : Seventy of the mental health checkups conducted by the National Mental Health Center among the nurses using tools including Perceived Stress scale, Fatigue Severity Scale, Patient Health questionnaire-15, Korean Beck Depression Inventory, Korean Beck Anxiety Inventory, and Symptom Checklist-90-Revision. Results : 12.9% of the patients experienced more than moderate somatization. There was no statistical relationship between somatization and psychological stress perception, but feeling of anxiety and decreased self-confidence were related to the level of somatization. The group with severe somatization experienced more depression and anxiety. The group with high physical fatigue also had no statistical relationship with psychological stress perception, but had an effect on the feeling of tension, stress, or decreased control. Physical fatigue level was increased by experience of depression, not by anxiety. For psychological symptoms the higher the level of somatization, the higher the obsession and hostility was explored. In the linear regression model, stress, depression, and anxiety accounted for 39.3% of somatization and 16.1% of physical fatigue symptoms. Conclusions : We can estimate the decrease in stress cognitive symptoms, accompanying depression and anxiety, compulsion and hostility as characteristics of somatization. The causal relationship between somatization and psychological symptoms cannot be confirmed in this study, but the interrelationships are observed, can be referred to mediation strategies.

This study examined the correlation between safety practices and safety knowledge, safety awareness and safety efficacy, and the factors influencing the safety practices of in-home child-care providers. The participants were 199 in-home child-care providers who worked at two cities in G province. Using a structured-questionnaire, the data were collected from December 2019 to January 2020. The data were analyzed using the IMB/SPSS 25.0 program. The collected data were analyzed using descriptive statistics (frequency, percent, mean, and SD), a t-test, ANOVA, Scheff test, Pearson Correlation Coefficient, and multiple regression. The mean score for safety knowledge, safety awareness, safety efficacy, and safety practices were 0.64 (SD, 0.09), 1.92 (SD, 0.37), 4.18 (SD, 0.51), and 2.55 (SD, 0.36), respectively. Safety practices were positively correlated with the safety knowledge (r=.14, p=.042), safety efficacy (r=.43, p<.001), and sub-factors of safety efficacy, self-regulation (r=.32, p<.001), enlisting social support (r=.40, p<.001), and controlling the environment (r=.39, p<.001). Enlisting social support and controlling the environment, sub-factors of safety efficacy were influenced safety practices significantly and explained 20.0% of the variance. Based on these findings, it will be necessary to develop a program that can enhance their safety efficacy for safety practices of in-home child-care providers.

The purpose of this study is to identify the characteristics and types of errors in the conceptual image of Korean language learners according to the types of terms in mathematics that are the basis for solving mathematical word problems, and to prepare basic data for effective teaching and learning methods in solving the word problems of Korean language learners. To do this, a case study was conducted targeting four Korean language learners to analyze the specific conceptual images of terms registered in curriculum and terms that were not registered in curriculum but used in textbooks. As a result of this study, first, it is necessary to guide Korean language learners by using sufficient visualization material so that they can form appropriate conceptual definitions for terms in school mathematics. Second, it is necessary to understand the specific relationship between the language used in the home of Korean language learners and the conceptual image of terms in school mathematics. Third, it is necessary to pay attention to the passive term, which has difficulty in understanding the meaning rather than the active term. Fourth, even for Korean language learners who do not have difficulties in daily communication, it is necessary to instruct them on everyday language that are not registered in the curriculum but used in math textbooks. Fifth, terms in school mathematics should be taught in consideration of the types of errors that reflect the linguistic characteristics of Korean language learners shown in the explanation of terms. This recognition is expected to be helpful in teaching word problem solving for Korean language learners with different linguistic backgrounds.

The purpose of this study was to provide the basic data necessary for stakeholders to establish and promote policies related to the national forest trail. Awareness analysis was conducted on 800 visitors to the national forest trail, specifically to the Jirisan trail and Daegwallyeong forest trail, as well as 1,200 members of the public. Awareness of the national forest trail was low and at a similar level for both visitors and the general public; however, compared with the general public, the visitors had a higher need for the national forest trail system and were willing to visit and recommend the trail. The most common answers in response to the purpose of visit, reason for choosing the national trail, matters of interest, problems, necessary regulation, and role expectations were similar among the visitors and general public. Based on gender and age, there was a significant difference in the matters of interest and desired activity, but "scenery" was the most crucial factor. Therefore, after a comprehensive survey on the major view points, given that "scenery" was identified as an attractor, a system should be developed to identify and provide the information desired by visitors and the general public. These results are expected to be employed as basic data for stakeholders in decision making related to the national forest trail.

The purpose of this study was to study the performance of volunteer work for the elderly from the perspective of self-efficacy and self-extension of the elderly, not from successful aging or productive aging. Through this, the research aims to confirm the expansion of internal growth and self-sufficiency that can occur in old age, and to provide an opportunity to re-examine one's life in old age. In order to verify the purpose of this research, questionnaires were distributed to 300 senior citizens who participated in volunteer activities at the City Hall and the District Office of Busan Metropolitan City over a period of three months from September to November 2018 and used the data from 266 questionnaires for the study, excluding the 34questionnaire answered unfaithfully. The results of the study are as follows. First, the motivation for volunteering activities (value function, social function, understanding function) of the elderly has a positive effect on self-efficacy. Second, the motivation for volunteering activities (value functions, social functions, understanding functions) have a positive effect on self-extension. Third, it has been shown that the elderly's sense of self-efficacy (self-regulation efficacy, confidence) has a positive effect on their self-extension. Fourth, it was found that self-efficacy has a mediated effect on the motivation of the elderly to participate in volunteer activities and the relationship of self-extension. This study identified the relevance of the motivation for volunteering activities of the elderly to influence their effectiveness and self-extension. In particular, the research suggests practical and policy measures for the revitalization of volunteer activities of the elderly by providing a new perspective on the welfare of the elderly by utilizing parameters of self-efficacy, a psychological and social concept for the elderly.

This paper examines whether angel investors affect startup's financial performance (profitability and growth ratios) in the Korean startup market over 10 years period from 2009 to 2018. In particular, we consider not only the behavior of angel investor such as the investment amount or the type of investments (stocks, bonds) but also the type of angle investor (individual or corporation). Our empirical results are as follows. First, we find that the startup's profitability ratios are higher after the investment of angel investors. However, the growth ratios show different results in assets and sales. Second, we identify that the investment amount of angel investors negatively affects on the startup's growth ratios. Lastly, we find that equity investment such as common stock or preferred stock and the individual angel investors such as personal investment association or professional angels show higher financial performance than bond investment or corporate angel investors. Overall, our findings imply that angel investors positively affect startup's financial performance. In particular, we infer that the superior financial performance is largely attributed to monitor startups by participating as shareholders or to select more carefully by the individual angel investors who may be exposed to more investment risk. In conclusion, our findings support that angel investors play a positive role in the Korean venture investment market.
