Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.

In this study, the longevity index was suggested for researches about social and environmental effects to human immorality and criteria for defining longevity area were developed using statistical analysis. Candidates indexes based on researches about the tend of human death ratio were investigated. As a result statistical analysis, ratio of population over 85 yearn old and over 65 years was selected as a longevity index. Statistical analysis on the longevity distribution at each district showed that 'eup' and 'myun' are appropriate spatial unit to study social and geographical characteristics of longevity. The spatial analysis using the ArcViewTM with the suggested index shows the time dependent variances of degree of immorality and spatial relationship between degree of immorality and human migration.

Spatially distributed characteristic of longevity regions analysed using GIS tools. Fundamental factors for long life are categorized into natural conditions and artificial conditions. Degree of longevity is defined and used as a key parameter in analyzing longevity region. It is visually shown that aging areas are moving with time and variances of social and economic status. It is concluded that the degree of longevity is increased with improving living quality because of improvement of economic activities and living environment. However, longevity regions of recent times have slightly reversed tendency against urban areas in the manner of moving toward areas where social and economical activities are relatively weaker.

Tobacco seeds (Nicotiana tabacum L. cv KF109) were primed in the polyethylene glycol 6000(PEG) solution and then stored at 5 and 25~circC under 40, 60 and 80% relative humidity (RH) conditions for six months. The effect of storage temperature and humidity on mean germination time (T50 ), longevity and germination of the primed tobacco seeds were compared. Untreated seeds (control) stored at 5~circC showed high germinability throughout the entire storage period and humidity, and a decline in germinability showed after 6 months at 60% RH and after 3 months at 80% RH when stored at 25~circC , Primed seeds retained high germinability until 6 months at 60% RH and 3 months at 80% RH when stored at 5~circC but showed a significant decline in germinability after 3 months at 40% RH, and 1 months at 60% and 80% RH, respectively when stored at 25~circC , Primed seeds were completely lost viability when stored at 25~circC under 60% RH for 6 months and under 80% RH for 3 months.

본 연구는 감마선 조사 시기, 강도 및 조사 후 보존제 처리가 절화장미와 국화의 수명에 미치는 영향을 알기 위하여 시행하였던 바 얻은 결과는 다음과 같았다. 절화장미의 경우 감마선 조사 강도가 0.5 KGy 까지는 절화품질에 미치는 영향이 적다고 할 수 있었으나, 이 보다 강한 조사구에서는 절화장미의 품질이 매우 악화되었으며, 조사 후 설탕용액에 침지한 것은 0.75 KGy 처리구까지 절화의 품질 유지효과가 인정되었다. 조사 후 절화보존제 침지
