  • Following public expectations from the emergence of an international agreement with greater legal force after the expiration of the 2012 Kyoto Protocol, Korea is also making efforts to effectively and systematically initiate the mitigation policy and enforce the terms of the international climate change agreement. The majority of domestic industries are candidates for greenhouse gas emission regulation, thereby requiring the proposal of a method that effectively reduces environmental contaminate substances released from railway facilities, following the prediction of an increase in railway usage as an environment-friendly transportation method in the future. Accordingly, this study has quantitatively calculated the amount of released environmental contaminates through the life cycle assessment (LCA) on railway facility constructions, and has evaluated the environmental load and the amount of greenhouse gas emissions through the resulting values. The results of the LCA analysis showed that the amount of environmental load was the highest at the early stages of material implementation and construction, and that the value of global warming was viewed as the highest among the effects. As officially announced by the World Meteorological Organization and the United Nations Environment Program that $CO_2$ is the main culprit of global warming, the analytical values confirmed that the amount of $CO_2$ emissions accounted for more than half of the released greenhouse gases at 2.90E+04tons. The environmental load and $CO_2$ emission rates analyzed in this study are judged to be used in the deduction of the optimum environment-friendly method and quantitative environmental effect of railway facility constructions in the future, as the values can be evaluated based on their degree of environment friendliness.

  • Along with the fast development of "smart"information technology including smart phones, a concern for increased productivity and better work-life balance is growing faster than ever. In many cases, the expectations for "smart work"remain only superficial at most, and the theoretical foundation for smart work research, much less with clear definitions, is not based on sound research. This article primarily aims to clarify the differences between the concept of telework and that of smart work. Particularly, a research framework for smart work, reflecting the points of differentiation for smart work on the basis of previous telework research framework is suggested. Then, we go further to discuss the limitations of existing telework research to suggest new research agenda for smart work research, and review current smart work policy being executed by the Korean government to suggest directions for the future. We expect to make academic contributions to the advancement of smart work research in the IS research field as well as provide practical insights for local policy planners.

  • The objective of this study is to provide basic data for building better exterior spaces for stadiums in the future by analyzing the behavior of users, such as the satisfaction measure and the physical environment, after using the exterior space at an existing stadium. To achieve this, multiple methods of data gathering and analyses such as field surveys, documentary surveys, and questionnaires research were used in this study. In the survey of user satisfaction, regression analysis was conducted on all factors. Factor analysis was conducted on the variables that were classified into physical, functional, social, and psychological factors. The factors were then tested and based on the results, multiple regression analysis was conducted to measure the effects of the factors concerning satisfaction. A questionnaire research on the use of the exterior space of a stadium as well as the social and economic backgrounds of the users was also conducted in order to utilize the results for the basic data for analysis of satisfaction. According to the results of this study, the exterior space of a stadium satisfied overall expectations. However, it is deemed important to introduce various facilities and activity programs and to improve the exterior spaces for users in building stadiums in the future.

  • This study categorized the households into four by the comparison of wives' and husbands' earned income, such as one with higher wives' income than husbands' in dual-earner households, with higher wives' income than husbands' in household with unemployed husbands, with lower wives' income than husbands' in dual-earner households, and with lower wives' income than husbands' in household with unemployed wives. This study compared and analyzed the objective and subjective economic well-being, and overall satisfaction of life in those households. Major results are below. First, the amount of expenditures, saving, debt were low in one-earner household with employed husbands, but average propensity to expenditure was high in those households. The amount of saving was low in one-earner households with unemployed husbands, but the average propensity to expenditure and debt were high, resulting in the low status of economic well-being. The amount of saving and monetary assets were high, but average propensity to expenditure and debt were low in households in which wives had higher income than husbands, resulting in the high status of economic well-being. Second, husbands' satisfaction for the level of family income was not different among four groups of households. Wives's satisfaction for those was the lowest when wives' income was higher than husbands', but the highest in households with unemployed wives. Wives' and husbands' expectations for the future economic well-being of the households were negative in households with unemployed husbands. On the other hand, the level of satisfaction of wives and husbands for their life was not different among four groups of households. Finally, four groups of households were discriminated by age of husbands, number of children, debt, and wives' expectation for the future economic well-being.

  • Shopping malls have become key players in the Indian retail space. Even in upcoming Indian towns, malls have been mushrooming. Raipur, the capital city of the Indian state of Chhattisgarh has witnessed the growth over the last few years. However, this unplanned growth of malls in cities is expected to lead to oversupply of mall space in the near future, making things difficult for mall developers. The study is an attempt to identify appropriate strategies for mall developers to iron out such kinks. This paper presents 'shopping experience' as a tool to compete, succeed and explore its composition in terms of its constituent factors. The paper uses Exploratory Factor Analysis (EFA) on a non-probability sample of 350 respondents. It condenses a set of twenty-two mall variables into five factors that directly influence the shopping experience. These factors included ambience, infrastructure, marketing focus, convenience and safety and security. In terms of significance, shoppers assigned different weightage to each of these factors. The study shed light on interesting insights regarding the expectations of mall shoppers in the city of Raipur. The results though interesting, may be extended to different social, economic and geographic contexts to check the universality. While strategizing, mall developers must assign proportionate effort on the factors based on the respective contribution to shopping experience. In light of intensifying competition in Raipur, the study is significant for future prospects of malls. In the absence of a scientific and objective basis, the developers run risk of making wrong investment and management decisions. This paper is a useful addition to the body of knowledge on management of shopping malls in India and is unique in terms of its focus on mall shoppers in the smaller Indian cities like Raipur.

  • This study analyzes marriage and fertility rates in Korea and makes recommendations for family policy. Based on the 'The Report of Marriage & Divorce Statistics in 2005' and data from the Korea Statistical Information System (KOSIS) of the National Statistics Organization, the trends, reasons for marriage rates changes, and future expectations were critically reviewed. In addition, the relationship between marriage and fertility rates was analyzed. The principle characteristics of marriage rates are as follows: 1) the M-shape of the longitudinal crude marriage rates; 2) the increased age of individuals entering their the first marriage; 3) the increase in remarriage rates; 4) the changes in the patterns of remarriage; 5) the increased in the age at which individuals remarry and; 6) the increase in marriage to non-Koreans. The marriage and fertility rates changes are a permanent normative shift because of 1) later marriage because of women's increased education and labor force participation 2) rational choices about birth control 3) reduced population because of the aging of baby boomers 4) structural changes in the marriage market and 5) egalitarian changes in women's attitudes toward marriage and family. The recommendations for future family policy were as follows: 1) the need for a realistic, long-term family policy because the current marriage patterns will continue; 2) the need to develop new statistics such as fertility rates that are based on marriage cohort or birth cohort because family behavior is a mixture of personal, social and political responses; 3) the need for impact analysis of current family policy about increasing fertility rates; 4) the need for a new family perspective that encompasses diverse marriage and family patterns; 5) the need to focus on men's role in families because of women's changing roles and family interaction patterns and; 6) the need for preventive family policies such as family life education.

  • The purpose of this study is to examine how providing care to grandchildren and the continuity of care affects the grandparents' perception on old-age support. Specifically, in this study, providing care is divided into three continuous types: did not provide care, provided care at one point in time and provided care at two points in time. This is done to investigate how the duration of providing care influences the perception on old-age support. The results show that grandparents providing care to their grandchildren prefer to reside with their own children in the future more often than those who do not provide care to their grandchildren. Furthermore, grandparents providing care to their grandchildren during two-time points and grandparents providing care during one-time point prefer to reside with their adult children in the future more than grandparents providing care not once during two-time points. Interestingly, grandparents who provide care to grandchildren during two-time points prefer to reside with their children in the future more frequently than grandparents providing care during just one-time point. These results suggest it is likely that grandparents recognize providing care to their grandchildren as an insurance in care and support for themselves in the future. Additionally, these results suggest that the family plays an efficient and flexible role to meet needs of family members through a reciprocal relationship in Korean society where the public sector is weak. These findings have suggested theoretical implications.
