The studies were carried out to investigate the occurrence of excessive dried leaves during burley tobacco curing. Six different periods of ventilation during the entire stage of curing were applied. And also 3 different heights of rolling up polyethlene film for side ventilation of the curing house combined with 4 different spaces between garlands were applied from after yellowing. The high air temperature and low relative humidity from end of yellowing to end of browning stage were the most critical to occur excessive dried \eaves. As side ventilation was continued for the entire stage of curing, air temperature in curing house was lower and occurrence of excessive dried leaves were remarkably decreased. The air temperature was not affected on hanging spaces, but relative humidity that resulted significantly in decreasing of the excessive dried leaves was increased by narrowing of hanging spaces. As excessive dried leaves were increased, its price per kg was lower, its physical properties was worse and its total nitrogen and total suger were higher than those of normal cured leaves.

The purpose of this study was to find out the characteristics of housing policies and apartment designs by comparison of supplying and remodeling apartments between France and Korea. The literature review was used in Korea cases and the literature review, site investigation, and expert interviews were used in France cases. At first, by reviewing the related literatures about the apartment developments and regenerations in France and Korea, twelve remodeling cases were represented respectively in Ile de France and Seoul. As a result, in housing policy, the Korean housing market had a shortage of low-priced houses related to biased apartment developments by private sector dependence. Consequently, the living in Korea generally required the high price in low quality houses. But in France, the housing policies were very successful in housing quantity, quality, and expense. It is involved in balances between the public housing supply and the activation of a private housing market based on the government support policy. Nevertheless, in the success of the apartment as a house type, apartments in France means the social elimination because of the supply method problems and the management failures of HLM institutions. However, in Korea, the apartment implies the successful life of the middle class population because of the competitive evolutions during 40 years as a market housing. Secondly, In the characteristics of remodeling, the remodeling in Korea was for property value improvements. It mainly executed to expand the size of a house by expansion of living space. However the remodeling in France was for social mixes and connections with the surrounding area. It mostly performed by various design methods such as vertical merging houses, partial removal, reconstruction, and construction of a local community centers and mixed-use residential buildings. This study shows the simultaneously remodeling features of those two countries. These findings can be used in developing effective strategies for the public housing regenerations in Korea and other countries.

The purpose of this study was to examine predictors of move intention to silver town in Jeju Island. Participants were 449 middle age and elderly who live in Seoul, Gyungido, Inchun Metropolitan and Jeju island. Participants were completed a questionnaire and/or structured interview that included measures of socioeconomic variables, motivation to move, determinants of move selection, conditions of location, and preparation for old age. Results of descriptive analysis revealed that cognition level of sliver industry and silver town was relatively high and medical service was the best necessary field, followed by field of leisure activity, house, life and finance. Logistic regression analyses on the effects of socioeconomic variables on move intention indicated that region, occupation and house ownership had significant effects on move intention to silver town. Result of motivational effect on move intention revealed that solution of offspring's burden was the most important factor, followed by convenient life of the aged, enjoyment of freedom for the elderly life. Result on the influence of determinants of move selection indicated that medical service facilities, resort facilities and leisure, cultural service facilities had significant effect on move intention. Among conditions of location for Jeju island, mild climate, comfort environment and low-price were significant predictors on move intention. Overall, result on relative influence of individual factors indicated that low price factor was the most important predictor, followed by resort facilities, cognition on necessity of silver town, enjoyment of freedom for the elderly life, leisure cultural service facilities, and medical service facilities.

We estimate the option value embedded in reverse mortgages using the framework of European put option. The reverse mortgage is a very useful financial product for senior citizens who own homes but do not have a cash income while it is a high risk one from lender's perspective. One of benefits of the reverse mortgages is that the debt limit is restricted to the scope of the disposition price of the collateralized house, which is considered a put option to borrowers. The put option is evaluated using Black-Scholes model and a sensitive analysis is performed on variables such as discount rate, volatility, and time period. We confirm that the option value of reverse mortgages increases rapidly as the borrowers live longer than their life expectancy. The results of this study can be used to promote the reverse mortgage program more effectively in order to solve the problem of income shortage of the elderly homeowners.

The purpose of this study is to investigate the architectural visual identity, and scheme of conceptional extent of architectural visual identity through literature research and sample analysis by design factors for apartment design. Korea National Housing Corporation's Mapo apartment put first caterer which is continued about 30 years to solve shortage of houses by beginning and the impact of IMF and the price decontrol on second half in the 1990s have changed the housing status to commercial goods. Construction companies have introduced brand concept to satisfy consumer's appetite in production of house goods including apartment under market situation. Importance of visual identity in apartment design occupies has risen in heftily. However most companies are in condition of stay on two-dimensional application that uses symbol, logotype, and character assistance. Several high position construction companies are trying architectural visual identity, but those are applied in partial element and those are not going forward to systematic classification and synthetic visual identity plan within peculiarity of apartment complex. This study is to grasp plan and design tendency to acquire identity of design element of construction field and goods through design examination. In conclusion visual identity in apartment design is architectural visual identity on all of 2 dimensions and 3 dimension for application. Architectural visual identity is a language of form that prescribe identity about external appearance in combination with brand image.

The aim of this study was to analyze differences in the perception of Gangwon-do residents using a satisfaction survey. The residents were found to be most satisfied with sectors such as parks/green spaces, landscape, and public order; however, they were least satisfied with transportation, culture, sports, medical services, and welfare facilities. Additionally, among all the items in the satisfaction survey, job satisfaction was the lowest. When comparing satisfaction trends observed in the city to those of the county, the overall satisfaction of the county was found to be slightly higher. This result could be attributed to young people being underrepresented in this survey in conjunction with the greater policy-level support for middle-aged people by from the government and Gangwon-do. Therefore, it would be worthwhile to create policies that primarily support young people and to also to create high-quality jobs with stable pay and employment prospects. This could minimize the outflow of youth and even encourage their inflow to similar small provincial cities. In Southern region and Seorak region of Gangwon-do, the satisfaction with gap between house price and region was low, which might be related to the increased demand for real estate throughout this area.

Purpose - The purpose of the research is to identify the demographic characteristics of the customers with high private label purchase intention. According to the previous research demographics such as gender, age, income, and residence type affect private label purchase intention indirectly through psychographics rather than directly. For instance, higher income group is time pressured, price-insensitive, quality-sensitive, less likely to enjoy shopping utilitarian products, and less likely to be variety-seeking. The main contribution of this research is to verify the results found in the previous empirical foreign research using scanner data and to investigate the differences of the characteristics of private label users between Korea and the foreign countries. Research design, data, and methodology - In order to empirically test the proposed hypotheses, scanner data of a Korean major super center was analyzed. Results - Empirical results show that private labels are more favored by old people over 50s, dwellers in individual house, lower income group, and frequent store visitors. Age of 30s, dwellers in the apartment of 30 pyung, higher income group, and consumers who purchased a large amount are less likely to purchase private labels. Gender turned out not to affect private label purchase. It should be noted that there is a significant multicollinearity among independent variables. Conclusions - The research findings provide managerial implication for retailers' private label strategy. In general, retailers heavily send private label coupons to the customers with high purchase volume. According to the research, however, store visit frequency is much more positively associated with private label purchase than purchase amount. The study has some limitations. The samples are only consumers with private label purchase experience. The data were drawn from one store and only 8 commodity products were used for the analysis. Also, if more demographics were available, a more complete description on the private brand users' profile could have been derived. We propose the following future research. Research using the data including consumers without private label experience, research investigating direction of causality between private label loyalty and store loyalty, and research using hedonic private label products such as TV and PC could be promising.

A total of 328 persons in Seoul, Kyunggi areas were selected by stratified random sampling method and were responded to this study questionnaire which was composed of six parts with 65 statements about chilled meat consumption. 1. The frequency of Dining-out is characterized that 'once a month' is the highest pattern of consumers(46.3%) : In that cases, the married people showed 'once a month'(52.7%) and 'once biweekly'(23.3%), but the unmarried people showed the more frequent pattern as 'once a week'(27.3%) and 'twice a week'(27.3%). And the frequency of Dining-out in relation with the education level revealed that 'the graduate people' are the highest (37.5%). 2. Generally the first food for the Dining-out is 'Kalbi'(26.2%), and the others were 'pork grilling','chilled meat grilling','fish sasimi','chinese foods','pizza' etc.... But there were some variation in relation with incomes and housing types: For the agriculture/physical labor class, they prefers the 'pork griling'(25.0%), the office work class prefers the 'Kalbi' For the house-owner group, they prefers the 'Kalbi', but the house-renting/lodging group, they prefer the 'chinese food' or 'pork grilling' etc.... 3. In choosing the Dining-out place,'quality of food'(54.3%) and 'hygiene'(21.0%) were rated as the first important factor. 4.'Soups', 'Noodles' and 'Cooked rice in casserole' were chosen as good lunch menu : for male, they prefer the 'Soups', but females prefer 'Cooked rice in casserole'. 5. People with commercials/services(44.7%) and agriculture/physical labor(50.0%) ate their lunch in private restaurant, but peoples in the office work(57.0%)/public service personnel(70.4%) and industry use refectory; and it showed significant difference. 6. Consumers prefer the chilled meat as a Dining-out menu, but they didn't recognize the difference between chilled meat and frozen meat 7.
