BACKGROUND: The 'Gamhong' cultivar, middle season apple with big fruit size and high soluble solid content, has been bred in Korea. However, it was hard to cultivate the cultivar in Korea by serious bitter pit. The relationships between shoot growth, fruit size, and bitter pit may be affected by crop load. This study was conducted for 2 years (7~8 years after planting) to investigate vegetative growth, fruit quality, bitter pit incidence, return bloom, and gross income for optimum crop load of 'Gamhong'/M.9 adult apple tree. METHODS AND RESULTS: The crop load was assigned to 4 different object ranges as follow: 45~64, 65~84, 85~104, and 105~124 fruits per tree. The vegetative growth, average fruit weight, percentage of fruits heavier than 375 g, soluble solid content, and return bloom increased significantly at the crop load range of 45~64 fruits. However, the lowest total gross income per tree may have been caused by the highest bitter pit incidence and the lowest yield per tree in any other crop load range. The total gross income and yield per tree increased significantly at the crop load range of 105~124 fruits and return bloom dropped to 40%, and hence it was possible to occur biennial bearing. It was 85~104 fruits that biennial bearing did not occur and total gross income was as high as the crop load range of 105~124 fruits. Also, the yield of high grade fruits per tree, with fruit weight of 400~499 g and none bitter pit on fruit surface, was highest at the crop load range of 85~104 fruits, compared to other crop load range. CONCLUSION: In considering fruit size, bitter pit incidence, return bloom, and gross income, the optimum crop load range of 'Gamhong'/M.9 adult apple tree in high density orchard was 85~104 fruits per tree.

Accurate subway demand estimation which is essential for better route selection can be achieved by the exact definition of the influence sphere of subway station. The influence was derived implicitly from the analysis of access time to the station for the cases of Seoul. Access time distribution was investigated by trip purposes, by age, by income, by sex, by travel distance, by kinds of thickets, by the location of station for the analysis of relationship between access time and socio-economic characteristics or urban structure. The difference of average access time between direct access trip and transfer trip which is found 8.6 minutes and 6.1 minutes respectively also investigated. The small difference implies poor transfer system of Seoul subway. 83.1% of subway users are coming from the distance of 10minutes' walk and average access time is 7.8minutes as a whole.

The purpose of this study were 1) to identity housing fund by the type of housing mobility and 2) to analyze the variable contributing to housing fund by the type of housing mobility. For these purposes, the 1993 KHPSD data was used and the sample in this study consisted of 2,796 couple households. Statistics employed for the analysis were frequencies, means, univariate analysis and multiple regression analysis. As the results, the composition and the amount of housing fund according to the type of housing mobility, were different respectively. Housing fund was consisted of previous housing sales price, savings deposits, loans, inheritance, subsidy, and personal debts. Households who already own houses used housing finance for their housing fund easily while renters were at a disadvantage to use housing finance. Moreover, among the contributing factors, home ownership, number of family member, residence, average monthly income, average monthly expenditure, husband's education attainment, satisfaction with housing, husband's job, and the type fo housing were positively associated with the amounts of housing funds. However, duration fo residence tended to negatively related to the amounts of housing funds.

This paper documents the presence of "sensitive sectors" in Free Trade Agreements, defined as sectors for which the within-FTA tariffs remain positive. The paper includes some brief theoretical discussion of the welfare implications of these, but the main emphasis is on reporting two measures of this phenomenon for countries in FTAs that entered into force between 1994 and 2003. One measure is the percentage of tariff lines that remain dutiable, and the second is the change, from before the FTA to after, in the average maximum (across 6-digit products) positive tariffs. Both measures are derived from data in the UNCTAD TRAINS database, and are then related to measures of country characteristics that might explain them. Low per capita GDP countries tend to have larger fractions of dutiable tariff lines, while higher income countries tend to post larger increases in average maximum positive tariffs. Both suggest that the favored treatment of sensitive sectors is undermining the potential gains from trade that FTAs could provide.

The purpose of this study was to investigate the actual conditions of successful ageing and the influencing factors focusing on social support from family and friends to improve elderly's quality of life. The 300 respondents, all participants in programs at facilities for the elderly, were interviewed via a questionnaire. The collected data were analyzed using SPSS 23.0. The results are as follows. First, the average score for successful ageing among the participants was above average. Second, the level of successful ageing varied according to income and religion. Third, the common variables affecting active or emotionally successful ageing were support from friends, subjective health conditions, and gender. It is suggested that the community should be informed of the importance of support from family through educational programs, as the elderly still want the support of family despite family's reduced role.

The purpose of this study is to analyze college students' TV advertising information recognition, comprehension and affecting factors on them. Data were collected by a survey of college student consumers after experiments with TV commercials. ANOVA, Duncan, and stepwise multiple regression analysis were carried out with the gathered data. The results are as follows. First, the TV advertising information comprehension degree of the college students consumers were shown to be low, by 41.2%. The comprehension degree was especially low when the information was presented visually without any verbal expression. Second, assuming that the comprehension of TV advertisements is defined by a correct perceptual understanding after recognizing the consumer-deception factors, the percentage of correct answers was poor, by 29.2%. Third, according to sex, average monthly income, degree of immersion on TV commercials, advertisement attitude, and consumer education of school, the TV advertisement information recognition and comprehension showed varying degrees between the groups. In the case of women students whose average monthly income was 100 to 300 thousand Korean won, had a high degree of immersion on TV commercials, and a high degree of consumer education at school, the TV advertising information recognition was shown to be high. In the case of third year college students who had a medium level of immersion on TV commercials and a high degree of consumer education at school, the TV advertisement comprehension was high. Fourth, the high explanatory factor of TV advertising information recognition and comprehension was found to be common because of consumer education at school.
