This research was conducted to grasp the characteristics of excessive sodium intake and its related factors in Korean middle-aged workers to help prevent and manage cardio-cerebrovascular disease. Study subjects were 40-59-year-old workers (n=1,438) who took part in the 2010 Korean National Health and Nutrition Examination Survey (KNHANES). Subjects were divided into: 1) a group that ingested more than 4,000 mg of sodium per day and 2) a group that ingested less than 4,000mg of sodium/day. We analyzed the relationship between general characteristics, sodium-related disease, health behaviors, and frequency of eating out with excessive sodium intake. The proportion of subjects with sodium intake of more than 4,000 mg/day was high in men, smokers, and drinkers. As educational level and frequency of eating out went up, so did the proportion of subjects with sodium intake more than 4,000 mg/day. It's necessary to educate the public and create policies regarding sodium reduction in middle-aged men for the prevention and management of cardio-cerebrovascular disease, and various approaches are necessary to reduce overall sodium intake in the restaurant environment.

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through $\chi^2$-test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teachers. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC than those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

This research was conducted to investigate the prevalence of depression and convergent factors related to depression in male and female wage workers. Using data from the 2014 and 2016 Korea National Health and Nutrition Examination Survey, 3,763 adults (1,888 males, 1,875 females) between the ages of 19 and under 65 were analyzed. Depression was measured by the Patient Health Questionnaire-9 (PHQ-9), and the depression (PHQ-9≥10) of all workers was 4.1% (3.2% for men, 5.0% for women). Multiple logistic regression analysis was performed to evaluate the depressive factors of male and female wage workers. In male workers, work-related characteristics such as employment type and working hours per week were found to be significantly related to depression even after adjusting for socio-demographic characteristics, health-related characteristics, and life style characteristics. However, in female workers, work-related characteristics did not expose a significant relationship, showing a difference from male workers. Therefore it is necessary to develop and implement workplace counselling or mental health promotion programs that take into account the gender characteristics of depression risk factors. Also, as health-related characteristics (diagnosis of depression, suicide plan, perceived stress level, unmet medical services, self-rated health status) were found to be related to depression for both male and female workers, continuous management of these factors is required.

The final goal of this study was to develop an optimal service scenario to ensure that building occupants can be effectively evacuated from the building within the golden time without extra assistance in preparing and evacuating for fires. In addition, the research was carried out by dividing the current services into fire evacuation and preparedness phases by applying the Double Diamond process in order to find a way to better familiar them as a lifestyle and to always be prepared for fires. For the building occupants and managers, a total of 14 ideas were first suggested, including not only the services of how to evacuate from a fire, but also the life-style service functions associated with fire implementation technology in daily life. The 14 proposed ideas were conducted by the Service quality evaluation and Analytical Hierarchy Process(AHP) from the perspective of the service recipient, and those were finally prioritized from the service provider's perspective, taking into account the cost and practicality of the service provider. The results of this study show that differences in the importance of fire phases considered by stakeholders and the perception of fire generally vary considerably.

OSINT(Open Source Intelligence), rapidly increasing on the surface web in various forms, can also be used for criminal investigations by using profiling. This technique has become quite common in foreign investigative agencies such as the United States. On the other hand, in Korea, it is not used a lot, and there is a large deviation in the quantity and quality of information acquired according to the experience and knowledge level of investigator. Unlike Bazzell's most well-known model, we designed a Korean-style OSINT-based profiling technique that considers the Korean web environment and provides timeline information, focusing on the improved workflow. The database schema to improve the efficiency of profiling is also presented. Using this, we can obtain search results that guarantee a certain level of quantity and quality. And it can also be used as a standard training course. To increase the effectiveness and efficiency of criminal investigations using this technique, it is necessary to strengthen the legal basis and to introduce automation technologies.

In traditional criminal cases, there is a limit to information collection because information on the subject of investigation is provided only with personal information held by the national organization of legal. Surface web-based OSINT(Open Source Intelligence), including SNS and portal sites that can be searched by general search engines, can be used for meaningful profiling for criminal investigations. The Korean-style OSINT workflow can effectively profile based on OSINT, but in the case of individuals, OSINT that can be collected is limited because it begins with "name", and the reliability is limited, such as collecting information of the persons with the same name. In order to overcome these limitations, this paper defines information related to individuals, i.e., equivalent information, and enables efficient and accurate information collection based on this. Therefore, we present an improved workflow that can extract information related to a specific person, ie., equivalent information, from OSINT. For this purpose, different workflows are presented according to the person's profile. Through this, effective profiling of a person (individuals) is possible, thereby increasing reliability in collecting investigation information. According to this study, in the future, by developing a system that can automate the analysis process of information collected using artificial intelligence technology, it can lay the foundation for the use of OSINT in criminal investigations and contribute to diversification of investigation methods.

Jeong Sun-Ah built up her performance career for twenty years with bold and energetic acting and solidified her status as a leading actress of Korean musical since her debut. To benefit from the value of her experience this study performed an in-depth interview with her, applying the Theory of "Projection" and "Back-projection", which are the psychological principles of acting, and derived "acting(entering the roles)" and "de-acting(leaving the roles)" techniques. As result, Her acting mechanism involved emptying her ego, embodying a persona by projecting the role created by intensive exploration of materials like previous performance, film of the same title, original novel, and script, and then getting the ego back by back-projecting through dynamic activities such as overseas travel and dance. She pre-studied the roles by physically visiting sites that are important to the characters. She was unique in that she pursued a difference by changing vocal trainers for each musical production and undertook more intense physical training than vocal practice to achieve powerful singing performance. In most of her works (75%), she suffered from aftereffects such as depression, narcissism, hysteria, and insomnia due to disorder caused by breaking away from the roles. However, she relied on self-help and alternatives are needed in the future such as reinforcement of expert counselling. Jeong Sun-Ah appeared on an average of 1.6 productions per year, practiced for an average of 1.7 months, and performed for an average of 3.9 months with an average of 100 days of break between productions. Her performance record from this research demonstrates her constant preparation and passion, as well as the know-how of reserving and distributing energy. So, it has a valuable implications for acting education and self-management of actors and actress.

The purpose of this study is to learn about the life style change experience of undergraduate due to COVID-19. The study was conducted from March 23, 2020 to March 30, 2020 and was conducted on five undergraduate residing in Jeonju. We valued individual's subjective experiences and analyzed them by applying on of the qualitative studies to identify and describe the phenomena as they are. The study found that the lifestyle changes of undergraduate due to COVID-19 were derived from three components: Psychological change, Environmental change, and Behavioral change. Though the participants felt uneasy and terrified by COVID-19 through the experience of psychological change, they expressed relief and anticipation for the increase in the number of complete healers. Experience of environmental change has experienced social distance, changes in academic operation, and difficulty in finding jobs to prevent infection. Behavioral changes have experienced a matrix of mask purchases and thorough management of personal hygiene, which is considered to protect oneself from COVID-19 while also being considerate to others. It is believed that the government will need to provide psychological and behavioral mediation programs for problems arising from the practice of social distance.
