As negative effects of climate change have been visualized and its direct damages to economy have been realized, the global efforts to respond to climate change by reducing greenhouse gas emission were accelerated. Korea's Carbon Footprint Labeling gets a lot of attention as one of the effective methods to contribute to national GHG reduction goal, and for enterprises to show customers how much effort the company put into global warming prevention. Consumers' interest on low-carbon products has been increasing. This study uses Life Cycle Assessment method to calculate the amount of carbon emission of dishwashing detergent, LG Household & Healthcare, which reduced carbon emissions by using raw materials that has relatively lower environment load. Life Cycle Assessment Method is based on guidelines of Carbon Footprint Labeling, Ministry of Environment, and pre-manufacturing, manufacturing, and disposal phase are included while use phase of the product is excluded from assessment. In order to understand the effects of eco-design on carbon emissions, the dishwashing detergent's carbon emissions are compared before and after the change of main raw materials. The result shows the improvement from $0.47kgCO_2eq/kg$ to $0.38kgCO_2eq/kg$ per product, and this means the main raw materials' carbon emissions could be reduced by around 9.4%, which is equivalent to 916tons of GHG emissions per year.

The purpose of this research was to find out the differences in the moving motivation and life satisfaction of senior cohousing communities between male and female residents in Scandinavia, especially in Sweden and Denmark. Senior cohousing is an attractive housing alternative for the aged 55 and over who looks for sharing one's life with neighbors. The 655 survey questionnaires out of 960 had replied from 14 Seniorbofrellesskaber in Denmark and 11 seniorhus within SABO sector and 8 housing cooperatives initiated by the Seniorgarden Housing Company in Sweden during April to May, 2002. The data were analyzed by SPSS win program, using frequencies, percentiles, cross-tabulations, and Pearson's correlations. The results showed that the senior cohousing residents were generally healthy and age of 70's years old and nearly half lived with a spouse. The male residents lived with a spouse about 2 times more than did the female. The residents had very strong motivation to move into the community and very high life satisfaction. Most aspects of moving motivation were not differed by the sex of the residents. However, male residents were more likely than female to be motivated to move in by becoming a pensioner, while female residents were more likely than male to be motivated by being a widow, looking for safety, or avoiding loneliness. These different motivation to move in by sex become more clear when general characteristics such as age, health status, living with or without a spouse, or country were controlled. Female residents were more likely than male to live' dream life' in the senior cohousing community. The stronger the moving motivation, the higher the life satisfaction in the community.

This study was a survey of consumer awareness and attitudes about genetically modified foods and their labeling regulations. Questionnaires were distributed to 4,620 consumers who lived in different areas of Korea, and 4,076 people responded. The consumers were asked about knowledge, labeling information, and their sources of information about GM foods. Respondents from Seoul, Jeonnam, and Gyeongnam answered mostly "nearly don't know > moderate > never know > know a little." Respondents from Gyeonggi answered "moderate > nearly don't know > never know > know a little." According to occupation, housewives, company employees, consultants, and students answered mostly "nearly don't know > moderate > never know > know a little. "Consumers answered about the intent to buy GM foods differently according to area, occupation, and education. Seoul and Gyeonggi residents said that reinforcing factors to relieve the insecurity of GM foods were "evaluating safety > management of GM foods by the government > GM food regulation system." There were other answers according to area, occupation, and education. About GM-related education methods that they wished to have, residents of the Seoul area said "books/leaflets" most often, but residents of the Gyounggi area said "attending a lecture" most often. Housewives also said "attending a lecture," but teachers and students said "Internetbased education" most often. About the kinds of education that they could join, Seoul residents answered "consumer groups > school parents > public institutions," but Gyeonggi and Chungnam area residents answered "public institutions > consumer groups > school parents." Housewives and students answered "consumer groups" most often, but consultants and private business owners answered "public institutions" most often. We realized that different education methods were necessary for different areas, occupations, and education levels.

Recently, many domestic and foreign corporates are concentrating in investment to wearable devices and users are provided with various service based on wearable devices 26% more than compared to last year. It is widely used in previous healthcare, smart work, smart home environment, and it is now introduced to get connection to fused service environment. However, as products of G company are commercialized, the security issue of personal information is causing dispute in society, and the danger of data management and security regarding telecommunication is increasing. Also, because the password system used in previous wireless environment is still in use, there are possible vulnerability considering the new and mutant security threat. This thesis conducted study about protocols that can exercise safe telecommunication in the basis of wearable devices. In the registration and certification process, the signature value is created based on the code value. The telecommunication method is designed to conduct safe telecommunication based on the signature value. As for the attack method occurring in the wearable device environment, the safety was analyzed and conducted performance evaluation of previous password system and proposal system, and verified about 14% of efficiency.

The obstructive factors of the smoothly running traffic are street improvement, major commercial buildings like department stores, the large markets, the stadiums, the concert buildings, a lot of steady cars for using parking lot. The accident of cost many lives and traffic congestion from these factors cause the result that it enables to pay the enormous expenditure socially and financially. For solving these problems, Japan adopts the Traffic Flagger System in 1972. This task has the effects of improving traffic flow in the traffic jam and mitigating risk of car accidents as leading pedestrians and vehicles thereby the task carries into effect in the area where the accident took place. Moreover, this security task is rapid growth after adopting and 59.6%(5,317) of the whole security company 8,924 in Japan based on December 2009 registered as the traffic leading security business. While South Korea is demanded of the measures about obstructive factors of the smoothly running traffic, it represents the limitation of the system and the safety management. Thus the current study suggests the we will analyze South Korea's actual condition and then discuss the law and education system for a realizable plan reached the public-Private cooperation for adopting Japan's Traffic Leading Security System.
