Understanding market convergence has became essential for small and mid-size enterprises. Identifying convergence items among heterogeneous markets could lead to product innovation and successful market introduction. Previous researches have two limitations. First, traditional researches focusing on patent databases are suitable for detecting technology convergence, however, they have failed to recognize market demands. Second, most researches concentrate on identifying the relationship between existing products or technology. This study presents a platform to identify the opportunity of market convergence by using product databases from a global B2B marketplace. We also attempt to identify convergence opportunity in different industries by applying Structural Hole theory. This paper shows the mechanisms for market convergence: attributes extraction of products and services using text mining and association analysis among attributes, and network analysis based on structural hole. In order to discover market demand, we analyzed 240,002 e-catalog from January 2013 to July 2016.

By studying the awareness level of students, for the need to protect personal information, and also by studying students' level of perception as to which information needs protection, this study aims to show that increased education is beneficial, and necessary, across all university majors. This increased education is necessary to improve information security, and increase the responsible sharing of private data which has many benefits, specifically in the Healthcare field. Utilizing student volunteers across multiple majors at a university in South Korea. These questionnaires measured the students' awareness of private information, their perception of private information and also the students' experience in receiving university level education regarding private information and the need for its protection. This study shows that, when compared to students in other fields, students in the field of public health had a higher level of awareness regarding the consequences of personal information disclosure for both public purposes and medical research. Within the parameters of this study, this outcome can be explained as the result of exposure to educational curriculum which contained information related to personal information protection. This increased education raised the student's awareness of which information is considered private, as well as, which information is valuable when responsibly shared. As a result, this study shows that an increase in education regarding information privacy, should be included in all university majors, and gives us evidence to support that this additional education is valuable to students at all levels and should be encouraged.

The purpose of this study was to analyze a change in Post-traumatic Stress Disorder (PTSD) level and the continuity of the effects in music therapy by applying short-term music therapy program in fire fighters with Post-traumatic Stress (PTS). Forty two fire fighters in 3 districts were randomly assigned to experimental group (21 subjects) and control group (21 subjects). Music therapy was applied in totally 10 sessions by two sessions (120 minutes) a day for 5 days. PTS level was measured immediately after the end of program, after 4 weeks, and after 12 weeks. As a result, PTS level has significantly decreased into $8.90{\pm}4.55$ from $26.52{\pm}2.32$ right after the music therapy program(p<0.05). And the effect was shown to be continued significantly up to after 4 weeks($11.95{\pm}4.57$) and after 12 weeks($13.76{\pm}5.62$)(p<0.05). As a result of research, it is considered that the music therapy is effective approach for reduction in PTS as for fire fighters who belong to the group with high risk of PTSD. Accordingly, the application of regular program for managing fire fighters' mental health is understood to likely to contribute to enhancing the field service competence.

A disaster can be defined in many ways based on perspectives, in addition, its types are able to classify differently by various standards. Considering the different perspectives, the disaster can be occurred by natural phenomenon that is like typhoon, earthquake, flood, and drought, and by the accident that is like collapse of facilities, traffic accidents, and environmental pollution, etc. Into the modern society, moreover, the disaster includes the damages by diffusion of epidemic and infectious disease in domestic animals. The disaster was defined by natural and man-made hazards in the past. As societies grew with changes of paradigm, social factors have been included in the concept of the disaster according to new types unexpected by new disease and scientific technology. Change the concept of social disasters, Ministry of Public Safety and Security (MPSS) has provided the regional safety index, which measures the safety level of a local government. However, this regional safety index has some limitation to use because this index provides the information for city unit which is a unit of administrative districts of urban. Since these administrative districts units are on a different level with urban and rural areas, the regional safety index provided by MPSS is not be able to direct apply to the rural areas. The purpose of this study is to determine the regional safety index targeting rural areas. To estimate the safety index, we was used for 3 indicators of the MPSS, a fire, a crime, and an infectious disease which are evaluable the regional safety index using an accessibility analysis. For determining the regional safety index using accessibility from community centers to public facilities, the safety index of fire, crime, and infectious disease used access time to fire station, police office, and medical facility, respectively. An integrated Cheongju, targeting areas in this study, is mixed region with urban and rural areas. The results of regional safety index about urban and rural areas, the safety index in rural area is relatively higher than in the urban. Neverthless the investment would be needed to improve the safety in the rural areas.

This study has examined how the welfare system has changed as it has passed through the most controversial period in Korean modern history. The welfare system has changed in a way that adapts to the need for export-led economic growth. Industrialization centered on light industry, which started in the mid-1960s, absorbed the labor force that existed in the rural areas and commodified them, thereby creating a momentum for Korean society to get out of poverty. However, the public de-commodification, ie social security system, adapted to the commodification of the labor force has been institutionalized only in a very limited area and people. Indeed, the de-commodification system was confined to the area directly linked to the reproduction of the labor force. Even so, the target was very limited in the abundance of labor in rural areas. Compulsory medical insurance was rejected because of corporate burden, and industrial accidents insurance was introduced centering on large-scale workplaces. As the Korean economy began to move from the light industry to the heavy industry in the 1970s, the commodificated labor force changed from a low skilled labor force to a skilled male labor force. It is at this time that dual structures have begun to be created between workers employed in export-oriented large enterprises and workers employed in domestic-oriented SMEs. Therefore, the system of de-commodification that supports the reproduction of labor power in response to social risks has also been institutionalized centering on large-scale workplaces.

Smartphone usage has become so common that it has reached 2 billion people in the last year. As a result of this, hospitals have started making use of smartphones at various medical sites and research services for patients. This study aimed to establish support for developing a long distance program for patients with implants who have difficulty visiting clinics or with busy modern lives, by using smartphones for oral hygiene management instruction. The data were collected for 12 weeks, from July 24 to October 21, 2015, for patients who agreed to participate in the study. Although the subjects found the process of transferring photos via smartphone to be cumbersome (75%), the satisfaction level of the oral hygiene management program was excellent for all participating patients, and they all wanted to continue with further management using this process. The results from the phone satisfaction survey showed that oral hygiene self-management after oral hygiene control training by smartphones was mostly equal to previous habits (87.5%) or had partially increased but had not decreased. The need for data on more varied age groups and the issues of protecting the security of personal information on smartphones require further study. However, our study confirmed the efficacy of using electronic media (smartphones) for oral hygiene management in patients with a dental implant due to their improvement of oral hygiene performance as evidenced by less bleeding from probing on post-program visit.

The purpose of this study is to analyze regional variation factors of hypertension treatment rate in COVID-19 based on the analysis results based on ecological methodology. To this end, data suitable for ecological analysis were collected from the Korea Centers for Disease Control and Prevention's regional health statistics, local government COVID-19 confirmed cases, National Health Insurance Corporation, Health Insurance Review and Assessment Service's welfare statistics, and Korea Transport Institute's traffic access index. Descriptive statistics and correlation analysis were conducted using SPSS Statistics 23 for regional variation and related factors in hypertension treatment rate, and geographical weighted regression analysis was conducted using Arc GIS for regional variation factors. As a result of the study, the overall explanatory power of the calculated geo-weighted regression model was 27.6%, distributed from 23.1% to 33.4% by region. As factors affecting the treatment rate of hypertension, the higher the rate of basic living security medical benefits, diabetes treatment rate, and health institutions per 100,000 population, the higher the rate of hypertension treatment, the lower the number of COVID-19 confirmed patients, the lower the rate of physical activity, and the alcohol consumption. Percentage of alcohol consumption decreased due to COVID-19 pandemic. It was analyzed that the lower the ratio, the higher the treatment rate for hypertension. Based on these results, the analysis of regional variables in the treatment rate of hypertension in COVID-19 can be expected to be effective in managing the treatment rate of hypertension, and furthermore, it is expected to be used to establish community-centered health promotion policies.

Background: As the population rapidly ages, older adults are increasingly likely to experience mobility problems. This study aims to explore the characteristics related to an elderly person's willingness to live in a nursing home if they have mobility problems Methods: This study analyzed data from 9,917 older adults (5,976 young-old and 3,941 old-old) obtained from the 2020 National Survey of Older Koreans. The dependent variable was the intended place of residence for older adults with mobility problems. Independent variables included various characteristics: (1) sociodemographic and social support, (2) health and functional status, and (3) residential environment. Rao-Scott chi-square tests and survey logistic regression analyses were performed for the young-old and old-old, respectively. Results: The intention to live in a nursing home was significantly different between the young-old (30.4%) and the old-old (34.7%) (p=0.009). According to fully adjusted multivariable analyses, for the young-old, the odds ratio of intending to live in a nursing home was significantly higher in social security benefit recipients (1.45; 95% confidence interval [CI], 1.06-1.97) compared to other individuals. The odds ratio was higher in unmarried (divorced, separated, widowed, or never-married) individuals for both young-old (1.41; 95% CI, 1.22-1.63) and old-old (1.34; 95% CI, 1.09-1.65) age groups, compared to their respective married counterparts. Conclusion: The results of this study suggest that in an aging society, health and social policies should be designed considering the different characteristics of the elderly to improve their health, function, and quality of life.
