The volume of unstructured text data generated by various social media has been increasing rapidly; therefore, use of text mining to support decision making has also been increasing. Especially, issue Clustering-determining a new relation with various issues through clustering-has gained attention from many researchers. However, traditional issue clustering methods can only be performed based on the co-occurrence frequency of issue keywords in many documents. Therefore, an association between issues that have a low co-occurrence frequency cannot be discovered using traditional issue clustering methods, even if those issues are strongly related in other perspectives. Therefore, issue clustering that fits each of criteria needs to be performed by the perspective of analysis and the purpose of use. In this study, a multi-dimensional issue clustering is proposed to overcome the limitation of traditional issue clustering. We assert, specifically in this study, that issue clustering should be performed for a particular purpose. We analyze the results of applying our methodology to two specific perspectives on issue clustering, (i) consumers' interests, and (ii) related R&D terms.

Technology for electric lighting has been evolving from Incandescent Lamp(IL) through Fluorescent Lamp(FL) and currently to Solid State Lighting(SSL) such as LED for more than 130 years of time. However, it took more than 100 years until the transition from IL to FL across overall society. That is because the transition is the Socio-Technical Transition(STT) which involves various social elements. This study investigated and analyzed the theories regarding STT, and applied the Multi-Level Perspective(MLP) theory to the case of electric lighting. A qualitative contents analysis was used with secondary data as research method, and the analyzed result was visualized based on the frame of MLP theory. The STT of electric lighting from IL to FL took place as the order of Technical Niche, Socio-Technical Regime and Landscape. Specifically, in Technical Niche level: Establishing Market Niche, Price-Performance Improvement, Learning Process and Support of Powerful Group took place. In Socio-Technical Regime level: Changes in Social Network, Changes in Technology and Changes in Rules. In Landscape level: Macro-Political Development, Socio-Economic Trends and Macro-Economic Trends took place in consecutive order.

In this paper, to analyze the meaning of middle-aged men's economic activities, TEXTOM was used to analyze them. The data collection period is set from 2017 to 2019. Among the collected data, 100 refined words were converted into a matrix in which the degree of social connection was calculated, and the keyword network analysis was performed again with the NetDraw program. According to the study, middle-aged men put more meaning on their current work and family than their future retirement. Also, the related word commonly included in the top five for all three years was 'work'. Related words commonly included in the top 10 were 'old age', 'family', and 'work', and in 2018 and 2019, 'health' was included in the top 10. As a result of this, the middle-aged men living in the modern age are the generation who keep their families through economic activities and are increasingly interested in health and prepare for retirement. Therefore, policy support for stable economic activities is needed to improve the quality of life for middle-aged men. It is necessary to extend the retirement age, expand jobs and provide effective vocational training so that it can handle its role as the head of a family. In addition, measures should be taken to reduce the wage gap between highly skilled and low-skilled workers.

The author recommends the creation of a nationwide career guidance program at the national level through the establishment of a long-term cohort, involving collaboration among medical schools nationwide. This cohort would be constructed for the purpose of analyzing correlations from admission to medical school to post-graduate education, facilitating the development of a career guidance program. This will aid in career development through students' self-analysis and competency building. Each medical school should operate a systematic career guidance program. Career guidance for post-graduate major selection should be included in the regular curriculum. Schools are advised to operate student counseling rooms for various career guidance services. For example, medical schools can operate 1:1 career counseling, academic counseling, career guidance surveys, psychological tests, and counseling. It is advisable to establish a mentor-professor system, connect mentor professors, and build a network of experts related to majors to provide immediate support according to students' needs. Professional mentor training should be provided to mentor professors. To provide opportunities for students to experience their career paths in advance, early clinical exposure, long-term integrated clinical practice, community-based clinical practice, participation in student research programs, career fairs, and student internship programs are recommended. In South Korea, it is necessary to systematically operate the internship system and make improvements to facilitate optical career choices. Additionally, considering the significant influence of social factors on students' career choices in South Korea, efforts should be made to identify and address the issues related to these social factors.

SNS is a platformwhere users build a social relationship and share opinions and informations. To do these, it supports a text, an image and a video data. As it is possible to exploit the location data of a smart device, SNS tries to use the location data. However,since SNS does not support the coordinate data, it provides the restricted function sharing the image map instead of the vector map. In this paper, we propose a chatting systemsharing pathsto support the coordinate data on a classical SNS. On the proposed system, it is possible for usersjoined in a roomto watch a vector map of same area and exchange texts. If a user builds a path on the map, the system propagates the coordinate data of the generated path and the other users joined in the room watch the path immediately. The implemented chatting systemhasthe benefit to share the information related a map between users using coordinate data.

Third, the ecosystem of co-operatives should be formed to support and foster legal systems and network organizations.

This study aims to discover the characteristics of Sino-South Korean cross-border small-scale trade, which involves various players. Through this characteristics, this study ultimately intends to identify an operational mechanism of Sino-South Korean cross-border small-scale trade by investigating social capital as mobilized by small-scale traders. The results of this study can be expected to help understand how small-scale merchants address the uncertainty or risks surrounding their trade. Although it is an informal economic activity, the cross-border small-scale trade between South Korea and China is related to issues of the formal economy, such as job creation, benefits for local economies, and profit-seeking. Owing to this characteristics, small-scale trade is being conducted with the connivance of, or even with the tacit support from formal organizations, including municipal governments, customs, corporations, and shipping companies. Like trade in other countries, Sino-South Korean cross-border small-scale trade also requires different types of social capital, such as family networks, ethnic networks, social networks, and trust.
