With increasing number of citizen using subway stations everyday, safety, health and comfort of passengers and occupants became an important social issue. Considering the fact that various physical variables and pollutants are related to indoor air quality (IAQ) which may cause health problem, IAQ need to be closely monitored and controlled in multiple locations in subway stations. This study is a continuation of the previous studies and delay induced in wireless-wired network is experimentally evaluated and the risk involved is assessed. In doing that, a key parameter is identified to be the network delay in different network media. Application of information-theoretic measure to assess the risk in network delay is then discussed. The idea is based on the general principles of engineering design and their applications to quantification of uncertainty in network delay. Experimental results show that more risk is involved in wireless data communication. Efficient and fast conversion of transmission data in both LonWorks/IP server and ZL converter is also noted.

Purpose - Along with emerging international entrepreneurship, there is a need for exploring the influencing mechanism of dual network embeddedness of the host country on international entrepreneurial performance. Drawing on network embeddedness theory and organizational improvisational theory, the present study constructs a theoretical model regarding the logic relationships between the dual network embeddedness of the host country, organizational improvisational capability, and international entrepreneurial performance. Design/methodology - Using a questionnaire survey, our study conducted data in two ways. The final research sample comprised 129 international new ventures. To test the hypotheses, a three-step mediation test method was conducted. Findings - Our empirical results suggested that both host-country social network embeddedness and industrial network embeddedness significantly affected the international entrepreneurial performance. Organizational improvisational capability significantly affected the international entrepreneurial performance. Third, organizational improvisational capability partially played mediating role in the relationship between the dual network embeddedness of the host country and international entrepreneurial performance. Originality/value - This study mainly concentrates on the two important types of host-country networks, host-country social network embeddedness and industrial network embeddedness, that may help international new ventures access the strategic resources necessary to support performance. Thus, it extends the existing network embeddedness theory and improvisational theory to encompass international entrepreneurship.

Background: The trend of aging society is occurring globally, and with it, one of the health problems that is emerging is frailty. Efforts are being made to account for the increasing prevalence of frailty, and various modifiable factors are being considered in regards to frailty. Because social contact has shown beneficial effects in terms of health in previous studies, it is increasingly being considered in relation to frailty. The purpose of this study was to assess the association of different types of social contact with frailty status. Methods: A total of 1,200 Korean elders aged 70-84 years old were included in the study. Using Fried's Cardiovascular Health Study index to categorize the frailty status, the relationship between frailty status and frequency of contact (i.e., with family members, friends, or neighbors) was analyzed using multinomial logistic regression accounting for confounders. Results: Adjusting for all covariates, frequency of contact with friends was the most statistically significant. Less frequent contact was associated with a significantly higher odds of pre-frailty: monthly (odds ratio [OR], 2.02; 95% confidence interval [CI], 1.27-3.20), and rarely (OR, 1.87; 95% CI, 1.17-2.99), with daily contact group as reference. Also, those contacting friends monthly (OR, 5.04; 95% CI, 2.29-11.08) or rarely (OR, 3.23; 95% CI, 1.58-6.61) were more likely to be frail compared to the daily group. Conclusion: Frequency of social contact, especially with friends, is strongly associated with frailty.

The purpose of this study is to analyze how the contents of education for sustainable development are reflected in the middle school environment curriculum revised in 2007, and to propose how to integrate content for improving sustainable development education. For this, I analyzed the 2007 Revised Environment Curriculum for Middle Schools by using social network analysis which is the useful methodology to understand the relations of contents. Social Network analysis is a useful tool to excavate the forms of structure or relationship and to explain the characteristics of the system that arise through relationships or to explain the units composing the system. When sustainable development education was examined from 3 points of view, it included environmental sustainability, economical sustainability, and social sustainability. I used the 2007 Revised Environment Curriculum for Middle Schools and manual of curriculum for analysis. The results are 1) The biodiversity conservation and energy efficiency have taken most important positions. 2) In case of economical sustainability pillar, sustainable production had been emphasized. 3) In the case of the social sustainability pillar, health improvement are considered significant. 4) The efforts of trying to approach sustainable development education as an integrated curriculum is week. Integrated themes based on the results were developed. Five main themes were the energy and climate change, water resource and environmental pollution, sustainable village and sustainable food production, sustainable city and sustainable production, sustainable tourism and biodiversity. I hope these could function as theme of integrated-content. Based on the results of study, I propose joint researches on scope of sustainable development for environmental education.

Because relationships established on expectations of every one involve depending on social network. There is lot of difference between emotional pain and physical pain. When you feel stress on physical body we all feel with tensions, stress on physical consequences, physical effects on our health. When we work on social network websites, developments or any research related information retrieving etc. our brain is going into stress. Actually by social network interactions like watching movies, online shopping, online marketing, online business here we observe sentiment analysis of movie reviews and feedback of customers either positive/negative. In movies there we can observe peoples reaction with each other it depends on actions in film like fights, dances, dialogues, content. Here we can analysis of stress on brain different actions of movie reviews. All these movie review analysis and stress on brain can calculated by machine learning techniques. Actually in target oriented business, the persons who are working in marketing always their brain in stress condition their emotional conditions are different at different times. In this paper how does brain deal with stress management. In software industries when developers are work at home, connected with clients in online work they gone under stress. And their emotional levels and stress levels always changes regarding work communication. In this paper we represent emotional intelligence with stress based analysis using machine learning techniques in social networks. It is ability of the person to be aware on your own emotions or feeling as well as feelings or emotions of the others use this awareness to manage self and your relationships. social interactions is not only about you its about every one can interacting and their expectations too. It about maintaining performance. Performance is sociological understanding how people can interact and a key to know analysis of social interactions.

Methods: The subjects were 504 foreign immigrant male workers over 20 years old who visited Daegu labor consultation center for oral health survey and oral examination. The questionnaire included 5 questions of socioeconomic characteristics, 8 questions of oral health practice behavior, 6 questions of dental clinic visit, 8 questions of social relations and Korean language proficiency. The question for health behavior was measure by body mass index(BMI). Social relations and Korean language proficiency instrument was modified by Seol from "Family welfare survey in Korean international marriage" and scored by Liker 5 scale. Results: The oral health examination of the immigrant workers was as follows: decayed teeth - 76.6%, filling teeth - 27.4%, missing teeth - 69.8%, dental caries experience above five or more - 60.2%, periodontal pocket tissues - 58.9%. Simplified Oral Hygiene Index was very poor and accounted for 49.0%. Dental care utilization experience was closely associated with social relation indexes including attendance in family events, household stuff help, financial help and counseling for hard work(p<0.01). Dental care utilization experience proportionally increased with proficiency in Korean literacy including speaking, listening, and writing abilities of Korean language(p<0.01). Conclusions: In order to improve the oral health condition of the immigrant workers, it is important to provide social network, Korean language proficiency support, and health insurance coverage through economic burden reduction by the Korean government.

Objectives This study aimed to evaluate the risk factors associated with depression and suicidal ideation in a rural population. Methods A survey was conducted with 543 farmers from Chungcheongnam-do Province using the Center for Epidemiologic Studies Depression Scale (CES-D) for depression, Lubben Social Network Scale (LSNS) for social support, Swedish Q16 for neurotoxicity symptoms and a survey tool for farmer's syndrome. Results After adjusting for socioeconomic factors using logistic regression analysis, poor self-rated health, low social support and neurotoxicity were positively associated with the risk of depression (odds ratio [OR], 15.96; 95% confidence interval [CI], 3.11 to 81.97; OR, 3.14; 95% CI, 1.26 to 7.82; and OR, 3.68; 95% CI, 1.08 to 12.57, respectively). The risk of suicidal ideation significantly increased with low social support, neurotoxicity and farmer's syndrome (OR, 2.28; 95% CI, 1.18 to 4.40; OR, 6.17; 95% CI, 2.85 to 13.34; and OR, 3.70; 95% CI, 1.51 to 9.07, respectively). Conclusions Given the overall results of this study, there is a need to establish programs which can improve the health and social relationships of farmers. Also, when farmers have neurological symptoms from pesticide exposure and characteristic symptoms of farmer's syndrome, a monitoring system for depression and suicide must be made available.
