Through the new round DDA(Doha Development Agenda) negotiations which started in Doha/Qatar conference in November, 2001, service industries have been included in the category of international trades. An electronic commerce cannot be exceptional in this field. The 21st century is largely recognized as the era of globalization, knowledge, and information. To make effective and competitive strategy in this century, it is essentially required to organize Network. OPEN, and FU-PLEX. That is why our government also has been promoting this field since years before, now 10,000,000 people in Korea have joined superhighway internet networks. Korea became the top internet-developed country in the world. As a side-effect of this internet spread into our life, however, there is serious problem we are now faced against. That is the outflow of private information through electronic commerce and other cyber transactions. It has caused many social problems to be rapidly on the rise these days. We are now desperately required to struggle continuously to make a solution for that. Taking the precedent case of Germany and United States which are currently recognized as high-leveled country in protection of private information, we have to come up with legal and technical measures and at the same time, to escalate the social consciousness about private information protection.

The rapid innovation of information and communication technology and its sharp falling prices have brought about the expansion of the Internet, integrating the world as one space under converged space and time. This rapid expansion of the Internet and its application in the economy have spurred the emergence of the digital economy. The Internet has influenced strongly on the changes of not only economic activities but also political, social and cultural activities. In this context, a rapidly increasing Internet expansion renders the rhetoric about the death of distance and about the meaningless of geographical place. However, the development and expansion of Internet induces a growing digital divide among nations and also a spatial inequality in a nation as the supply of the Internet has concentrated towards demand-affluent large cities. A large gap of digital access has been occurred between high income and low income countries according to a measurement of the international digital access index. In a national level, the Internet backbone has been built around large cities which favor a large amount of the Internet demand, and the affordable accessibility of these cities for the Internet services has influenced strongly on the agglomeration of Internet related industries, further inducing the construction and investment of the Internet backbone into large cities as cumulative causation effects. As a result, the expansion of the Internet affects immensely on the changes of spatial structure in a nation resulting in the new spatial phenomena such as centralization, concentration and splintering in the digitalized space-economy.

The purpose of this study was to understand changes in domestic forest policy and social perception of forests from a macro perspective using big data analysis of news articles and editorials. A total of 13,570 'forest' related data were collected from metropolitan and economic journals from 1946-2017 using keyword and CONCOR (Convergence of iterated Correlations) analysis. First, we found the percentage of articles and editorials using the keyword 'forest'increased overall. Second, news data on 'forest' in the field of reporting was concentrated in the "social" sector during the first period (1946-1966), followed by forest-related issues expanding to various fields from the second (1967-1972) to fifth (1988-1997) periods, then toward the "culture" sector in the sixth (1998-2007) and "politics" after the seventh (2008-2017) period. Third, we found changes in the policy paradigm over time significantly changed social awareness. In the first and second periods, people experienced livelihood issues rather than forest greening or forest protection policy and expanded their awareness of planned and scientific afforestation (third) to environmental protection (fourth) and ecological perspectives (sixth to seventh). The key outcome of our analysis was leveraging news big data that reflected polices on forests and public social perception To further derive future social issues,more in-depth analysis of public discourse and perception will be possible using textual big data and GDP of various social network services (SNS), such as combining blogs and YouTube.

The purpose of this study was to understand family changes and dynamics of and to suggest institutional/policy-level tasks for coping with them, by paying attention to changing family values of single-person households and their caring work performed in everyday life. This study selected 11 single-person households residing in Ulsan by considering their age and marital status, and analyzed their overall daily lives, family values, and the characteristics of household work and caring. The characteristics of these single-person households in Ulsan, not only showed the coexistence of "simplicity, but instability" when maintaining and living their own lives, but also showed the ambivalent characteristics of family values by showing a gap between the perception and reality of diversity. In regard to family life, the participants complained of difficulties in "caring and relationship of family of origin" and the "economic factors", and notably showed the "dual value system". For a more stable life, the single-person households were forming social networks to relieve a sense of isolation and loneliness, and to recover relationships, instead of limiting themselves to only the traditional method of family formation. Thus, it would be possible to respond to family changes when changes are promoted in each area of "the perception of life", "family life", and the "family & social relationship", and this research suggests policy-level tasks based on the results of this study.

The social networking service (SNS) is free, but the data usage fee paid to the telecommunications company and the member's information must be provided directly or indirectly. In addition, while SNS' specifications for transmitting and receiving devices such as smart-phones and PCs are increasing day by day, using universal transmission protocols in special environments such as contaminated areas or semiconductor manufacturing plants where work instructions are mainly made using short messages is not easy. It is not free and has a problem of weak security. This paper verified the practicality through the operation test by implementing IMCP, a low-power, low-cost message transmission protocol that aims to be wearable in special environments such as risk, pollution, and clean zone based on ATmega128.

Objective : This study aimed to categorize the lifestyles of older adults into two types - healthy and unhealthy, and use machine learning to identify the personal values that influence these lifestyles. Methods : This cross-sectional study targeting middle-aged and older adults (55 years and above) living in local communities in South Korea. Data were collected from 300 participants through online surveys. Lifestyle types were dichotomized by the Yonsei Lifestyle Profile (YLP)-Active, Balanced, Connected, and Diverse (ABCD) responses using latent profile analysis. Personal value information was collected using YLP-Values (YLP-V) and analyzed using machine learning to identify the relative importance of personal values on lifestyle types. Results : The lifestyle of older adults was categorized into healthy (48.87%) and unhealthy (51.13%). These two types showed the most significant difference in social relationship characteristics. Among the machine learning models used in this study, the support vector machine showed the highest classification performance, achieving 96% accuracy and 95% area under the receiver operating characteristic (ROC) curve. The model indicated that individuals who prioritized a healthy diet, sought health information, and engaged in hobbies or cultural activities were more likely to have a healthy lifestyle. Conclusion : This study suggests the need to encourage the expansion of social networks among older adults. Furthermore, it highlights the necessity to comprehensively intervene in individuals' perceptions and values that primarily influence lifestyle adherence.
