Using the first wave of KLoSA(Korean Longitudinal study of Aging) beta version, this study analyzed factors affecting retirement adjustment by elapsed time from retiree's retirement through Binary Logit and Multinomial Logit Analysis. Participants were 1,780 retiree. The main results of this study were as follows : First, The retiree's education(-), health status(-), region(+), dwelling type(-), monthly household income(-), employment type before retirement(+), retirement reason(+), and the elapsed time from retirement(-) were affected whether they satisfied with pre-retirement or not. Second, The gender(-), age(-), and the region(+) were affected whether they satisfied with life after retirement or not. Third, The gender(-), age(-), education(+), heath status(+), dwelling type(+), monthly household income(+), retirement reason(-), and the elapsed time from retirement(+) were affected on their satisfaction after retirement compared to pre-retirement. Last, The different factors affected the life satisfaction after retirement by elapsed time from retirement.

Incidence of the Fusarium wilt caused by F. oxysporum f. sp. vasinfectum of sesame (var. Kwangsan) was remarkably influenced by seeding date and mean air temperature in the field of two or three year's continuous cropping with sesame in 1983 and 1985. Sesame were seeded on six different dates from April 20 to July 5. Air temperature was checked daily at the meteorological station near the experimental field. Low($16{\sim}20^{\circ}C$) and high temperature($20{\sim}25^{\circ}C$) periods were provisionally devided, based on every ten-day mean daily temperature during field experiment for last ten years, which corresponded to before and after June 15 in Jinju, Gyeong-nam. Infection rates were 83.7%, 68.2% and 59.4% in the plants grown for 55 days (seeding date: April 20), 40 days(May 5) and 25 days(May 20) under low temperature. On the other hand, infection rates were below 3% in those plots seeded during high temperature period. The longer the growth period exposed to low temperature, the higher was infection rates. It is interesting to note that 40 days old seedling or older are prone to severe infection compared to the younger ones, in higher temperature of $20{\sim}25^{\circ}C$. Therefore, seedlings in vegetative growth stage are less prone to infection than these in reproductive growth stage. The result showed that air temperature during sesame growth was one of the most important factor affecting the incidence of Fusarium wilt. This suggested that sesame crop, which is of tropical origin, has been predisposed to Fusarium wilt, when the plants were exposed to low temperature of $16{\sim}20^{\circ}C$.
