This study aims to understand why the sales volume and the number of visitors are different in each rural tourism village. The study considered that the management and operation of rural tourism villages is one of the major influencing factors. To prove this, the study determined what factors were related to the management and operation of villages and derived detailed items to evaluate them. In the study, the researchers conducted an in-depth interview and a literature review on the management and operation of rural tourism villages in Yangpyeong-gun. They also performed a case study on the Sumi village, one of the successfully managed and operated villages in Yangpyeong-gun, to determine the detailed items. As a result, seven factors were identified. These factors comprise operation entity, governance, shared vision, leadership, efficient role-playing, marketing efforts, and equity in profit distribution. Based on these seven factors, 85 of the evaluation items were developed. The management and operation scores of 85 items were measured and summed for each of the 21 rural tourism villages. First, 21 villages were divided into two groups by the sales figures to derive items to determine the difference in the mean value of the evaluation scores. Second, an independent sample t-test was conducted for each village at YangPyeong-gun. Third, the study divided the 21 villages into four groups using 46 evaluation items. Finally, the study's researchers clarified some challenges to solve and appropriate management and operation plans considering each type of rural tourism village.

A 4.4 kb DNA fragment encompassing lacA (galactoside acetyltransferase) and lacZ($\beta$-galactosidase) genes from Lactococus lactis ssp. lactis ATCC 7962 (L. lactis 7962) was introduced ito a Lac strain, Lactococcus lactis ssp. lactis MG1363 (L. lactis MG1363) by using a lactococcal expression vector, pMG36e and expression level of lacZ was examined. Growth rates and $\beta$-galactosidase ($\beta$-gal) activities of MG1363 cells carrying recombinant plasmid, pMLZ3, on M17 broth containing different carbon sources (1%, w/v) were examined. Contrary to the expectations, MG1363 [pMLZ3] grown on lactose showed the lowest enzyme activity (17 units) and cells grown on galactose had the highest $\beta$-gal activity (41 units). Cells grown on glucose had intermediate activity (33 units). These activities are about one tenth of the values observed in L. lactis 7962 where lacZ is present as a single-copy gene in the chromosome. When the cellular concentrations of lacZ transcript were examined using slot blot hybridization, it was found that MG1363[pMLZ3] produced sufficient amounts of transcript. These results indicate that either proteolytic degradation of $\beta$-gal or other regulatory mechanism prevent the translation or accumulation of $\beta$-gal in L. lactis MG1363 cells. In regard to regulation, the presence of the ccpA gene in L. lactis MG1363 was confirmed by Southern blot.

The effects of growth temperature and a carbon source on the expression of $\beta$-galactosidase gene of Lactococcus lactis ssp. lactis ATCC 7962 (L. lactis 7962) were investigated. At $25^{\circ}C$, L. lactis 7962 had a higher $\beta$-galactosidase activity than cells grown at $30^{\circ}C$ or $37^{\circ}C$, although cells grew most quickly at $37^{\circ}C$ The highest $\beta$-galactosidase activity was observed in cells grown in M17 with lactose (l %) followed by cells grown in a galactose (1 %) medium. L. lactis 7962 exhibited the minimum $\beta$-galactosidase activity in glucose media, indicating catabolite repression. When the cellular levels of $\beta$-galactosidase mRNA were examined using slot blot hybridization, no significant differences were observed between cells grown at $25^{\circ}C$ and cells at $30^{\circ}C$ or $37^{\circ}C$ in the same media. This suggests that the quantity of $\beta$-galactosidase mRNA may not be the reason for the higher $\beta$-galactosidase activities of L. lactis 7962 at $25^{\circ}C$ The level of ccpA (Catabolite Control Protein) transcript remained almost constant during the exponential growth phase irrespective of a carbon sourse.

Landscape change is the modification and replacement of landscape elements in accordance with human management and natural disturbance on land mosaics. During landscape change, changes in patterns such as heterogeneity, diversity and shape, and juxtaposition of spatial elements are also accompanied. For the sustainable landscape system, therefore, spatial characteristics of the landscape should be considered in implementation of landscape conservation and restoration planning. Short-term changes of land-use and landscape pattern during the 10 years of 1980s and 1990s were investigated in the agriculture-forestry dominated landscape system through the statistics and the analysis of landscape-vegetation map. Study area is Yangdong-myon, Yangpyung-gun (37°27′30"N, 127°46′50"E), Kyonggi-do, in central Korea. Landscape change of this region was significantly related to the recent industrialization according to socio-economic development. Analyses of landscape pattern show that the area of secondary forest sustained by human activity decreased and it was replaced with large exotic plantations during this period. Area of paddy field was also extended. Fractal dimension of the total landscape increased, but that of paddy field area decreased due to rearrangement for mechanized farming. Moreover, the area of landscape management regimes such as plantation and cultivation increased in land mosaics during this period.

The application of the cellulase gene (celA) as a selection marker of food-grade integration system was investigated in Lactobacillus (Lb.) casei, Lactococcus lactis, and Leuconostoc (Leu.) mesenteroides. The 6.0-kb vector pOC13 containing celA from Clostridium thermocellum with an integrase gene and a phage attachment site originating from bacteriophage A2 was used for site-specific recombination into chromosomal DNA of lactic acid bacteria (LAB). pOC13 was also equipped with a broad host range plus replication origin from the lactococcal plasmid pWV01, and a controllable promoter of nisA ($P_{nisA}$) for the production of foreign proteins. pOC13 was integrated successfully into Lb. casei EM116, and pOC13 integrants were easily detectable by the formation of halo zone on plates containing cellulose. Recombinant Lb. casei EM 116::pOC13 maintained these traits in the absence of selection pressure during 100 generations. pOC13 was integrated into the chromosome of L. lactis and Leu. mesenteroides, and celA acted as an efficient selection marker. These results show that celA can be used as a food-grade selection marker, and that the new integrative vector could be used for the production of foreign proteins in LAB.

Recently, interest in organizational performance has been increasing due to marketization and diversification of supplier introduced in long-term care system. To analyze the effects of caregivers' calling on the organizational performance of long-term care facilities and to examine the mediating effects of job satisfaction on the path, data were collected from caregivers in Seoul and Kyonggi-do. Multiple regression analysis was used to examine the effect of caregivers' calling on job satisfaction and job performance, and the mediating effect of job analysis was tested by hierarchical regression analysis. As a result, caregivers' calling had a positive effect on job performance and job satisfaction, and the job satisfaction showed full mediation effect between caregivers' calling and effectiveness and partial mediation effect between caregivers' calling and efficiency. Based on this, we discussed the need to improve efficiency through job satisfaction management and to manage efficiency by managing job satisfaction and vocation awareness.

The purpose of this study was to investigate housing situation and residential satisfaction of foreigners in Korea, and to identify influential factors for housing satisfaction. A questionnaire survey was conducted to 132 foreigners who reside in Seoul and Gyeonggi-do. Most of the respondents were Chinese and the average age was 45.7. Over 90% of the respondents lived in a rented house and detached house was the most popular type of house. Overall score of residential satisfaction was 3.43 and it was above average. However, scores for parking lot, housing deterioration, and space planning showed the lowest level of satisfaction. Factor analysis was used to summarize the variables related to residential satisfaction and 5 factors -'space planning and organization,' 'amenities & equipment', 'community facilities,' 'near environment' and 'housing expenses'- were drawn. Among those, 'space planning and organization' was the most influential factor to residential satisfaction as the result of multiple regression analysis.

This study was intended to grasp the actual condition of adult women's wearing foundation garments for the Korean adult women in their 20s to 40s. For this purpose, questionnaire research was conducted for 639 adult women in their 20s to 40s living in Seoul and Kyonggi Province. As for the reason for the purchase of foundation garments, It was found that the highest proportion of the responding adult women would buy brassieres when they were needed because the old ones were threadbare, followed by the purchase of brassiere when they caught their eyes in shopping around. As for the reason for the purchase of girdles, the highest proportion of the responding adult women could buy girdles when they were needed because their old ones were wornout, and next when bargain sale began at the department store or the large shopping center. The highest proportion of the responding adult women thought the source of information on foundation garments as the window display, followed by magazine. The adult women in their 30s collected information on foundation garments through the window display when buying brassieres or girdles. As for the product evaluation criteria of foundation garments, the highest proportion of the responding adult women thought highly of the feeling of wear in brassieres and girdles, followed by dimensions in brassieres and bodily correctability in girdles. As for the place of buying brassieres or girdles, the responding adult women showed it to be the department store. followed by the discount store and the well-known agency.

When a spatial regression model that uses kernel density values as a dependent variable is applied to retail business data, a unique model cannot be selected because kernel density values change following kernel bandwidths. To overcome this problem, this paper suggests how to use the point pattern analysis, especially the L-index to select a unique spatial regression model. In this study, kernel density values of retail business are computed by the bandwidth, the distance of the maximum L-index and used as the dependent variable of spatial regression model. To test this procedure, we apply it to meeting room business data in Seoul, Korea. As a result, a spatial error model (SEM) is selected between two popular spatial regression models, a spatial lag model and a spatial error model. Also, a unique SEM based on the real distribution of retail business is selected. We confirm that there is a trade-off between the goodness of fit of the SEM and the real distribution of meeting room business over the bandwidth of maximum L-index.

This research was conducted to develop recommendations for the accreditation system of child care programs in Korea. To assist families in choosing the best child care for their children and to promote excellence in child care settings, an accreditation system of child care programs is necessary. The survey subjects were 262 public, private and corporation child care directors in Seoul, Kyonggi, and Inchon areas. The findings showed that 79.8% of the directors agreed with accreditation systems but they strongly insisted that the necessary time to apply must be well considered with 65.6% of the directors responding that $1{\sim}3\;years$ later was a good time to apply and 37.4% choosing the child care environment as the major area that should be evaluated among the 7 indices of the accreditation system. Most directors were in favor of 7 areas as the indices of accreditation systems while more educated and early childhood education majored directors were more affirmative of the accreditation system.
