  • Carbon neutrality in agriculture can be derived from systematic GHG reduction policies based on quantitative environmental impact analysis of GHG-emitting activities. This study is to explore how to advance the calculation of carbon emissions from agricultural activities to the detailed spatial level to a spatial Tier 3 level (Tier 2.5 level), methodologically beyond the Tier 2 approach. To estimate the GHG emissions beyond the Tier 2.5 level by region for detailed spatial units, we constructed available activity data on carbon emission impact factors such as rice cultivation, agricultural land use, and livestock. We also built and verified detailed data on emission activities at the field level through field surveys. The GHG emissions were estimated by applying the latest national emission factors and regional emission factors according to the IPCC 2019 GL based on the field-level activity data. This study has significance that it explored ways to build activity data and calculate GHG emissions through statistical data and field surveys based on parcels, one of the smallest spatial units for regional carbon reduction strategies. It is expected that by utilizing the activity data surveyed for each field and the emission factor considering the activity characteristics, it will be possible to improve the accuracy of GHG emission calculation and quantitatively evaluate the effect of applying reduction policies.

  • Predicting factors of post-stroke depression were investigated. The subjects were 254 stroke patients who had been discharged and visited regularly the outpatient clinic for follow up care. The influencing factors were classified into five categories : demographic, disease-related, current state, social support, and illness intrusiveness. Sex, age, job, and educational level were defined as the demographic factor. The disease-related factors included stroke type, illness duration, attack frequency, and NIH score. ADL, cognitive function, and social activity were considered as the current state factors. The social support was measured as the perceived amount of social support. Illness intrusiveness means the perceived illness induced life style disruptions. Demographic, disease-related, current state, and social support were hypothesized to directly and indirectly affect post-stroke depression through illness intrusiveness. The illness intrusiveness was hypothesized to directly affect post-stroke depression. The hierarchial multiple regression was used to identify significant factors. The result showed that this model explained 43.3% of variance of post-stroke depression. And the prevalence of post-stroke depression was 38.8%. Among the demographic factors, job was identified as a main contributor to indirectly increase the post-stroke depression. Among the disease-related factors, stroke type, attack frequency, and NIH score were found to indirectly affect the post-stroke depression. Among the current state factors, ADL and social activity indirectly affected the post-stroke depression through illness intrusiveness. Social support and illness intrusiveness were identified to directly affect the post-stroke depression. This study has proved the factors likely to be implicated in the development of post-stroke depression. Based upon these results, it is recommended that the nurses who take care of post-stroke patients consider the risk factors such as social support, illness intrusiveness et al. Also programs which decrease the illness intrusiveness and increase the social support to reduce post-stoke depression recommended to be developed.

  • This paper discussed about creativity and knowledge management variables as for effect factors on the management performance of IT service firms. Specially the mediation effects of knowledge management variables between the creativity and management performance were examined. To prove empirically the related hypothesis, the statistical analysis were based on the response from the 160 Korean IT Service firms. As an analysis results, it was found that the creativity of organizations was not the direct effector on the management performance. But the virtue of knowledge which are accumulated from knowledge management activity and shared in organizations was the direct effector. Also, the knowledge management activity is mediator on the in the relationship between the creativity and management performance. So this paper suggests that knowledge management activity and knowledge's virtue in the related the creativity in organizations are the important mediate factors for enhancement of IT service firm's performance.

  • Autophagy is an evolutionally conserved cytoplasmic degradation system in which varieties of materials are sequestered by a double membrane structure, autophagosome, and delivered to the lysosomes for the degradation. Due to the wide varieties of targets, autophagic activity is essential for cellular homeostasis. Recent genetic evidence indicates that autophagy has a crucial role in the regulation of animal lifespan. Basal level of autophagic activity is elevated in many longevity paradigms and the activity is required for lifespan extension. In most cases, genes involved in autophagy and lysosomal function are induced by several transcription factors including HLH-30/TFEB, PHA-4/FOXA and MML-1/Mondo in long-lived animals. Pharmacological treatments have been shown to extend lifespan through activation of autophagy, indicating autophagy could be a potential and promising target to modulate animal lifespan. Here we summarize recent progress regarding the role of autophagy in lifespan regulation.

  • The purpose of the study is to researdch clothing consumer behavior of men and women over age of 20 years and to find out the reasonable maximum utility on clothing behavior. The factors are eight distinguished parts such as sex, age, monthly income, occupation, floor space, number of room, number of family and place of residence. A common questionaire is introduced to survey the clothing consumption activity and the home background. Sources to measure them are gathered in the whole country including major cities. The questionaire of 915 correspondents of 368 males and 547 females is investigated for this research. Some of the data are analyzed by correlation, frequency, percentage, mean, and S.D. Others are investigated by ANOVA Test, x2-Test, and Multiple Range Test. The results from the survey are as followings: 1. Only four factors such as sex, monthly income, occupation, and floor space have a significance in the clothing consumption activity. 2. This survey reveals that many cloths have been kept in dead storage and concerns of utility have risen high. 3. This survey has shown that the correspondents have deep concerns about using colthing exchange store, clothing lending store, and trunk room to utilize dead storage clothing efficiently.

  • Phorbol ester, growth factors activities are mediated by unclear transcription factors, the c-Fos and c-Jun, which can regulate transcriptional activation through specific DNA sites and by forming the transcription factor AP-l, which usually mediates cell proliferation and differentiation signals. We explored effects of Pini Folium extract (API-l) on AP-l activity. Western blot analysis confirmed that API-l decreased levels of c-Fos or c-Jun protein induced by the tumor promoter Phorbol 12-myristate 13-acetate (PMA; 200 nM). Transient transfection assays with a c-fos promoter reporter construct showed that API-l decreased transcription activity by ore than 50~60%. However, treatment of API-l activity studied further. The main substances were fractionated into dichloromethane layer. Futhermore, API-l extract repressed the [$^3H$]-thymidine uptake in C6 glioma cells, indicating that this extract could be included in a new type of modulator in the mitogenesis.

  • The purpose of this study is to compare the satisfaction of the urban parks and to classify and assess the environmentally-friendly behaviors in the urban parks. For this purpose, the park user's behaviors and satisfactions were surveyed in 10 parks in Seoul and its suburb area. Parks are divided into 2 types, the walking-distance parks and the metropolitan parks, by time to reach, visit frequency and visit purpose. The park users are generally satisfied with the facilities, but not satisfied with some specific items, such as cultural facilities, accommodations for the handicapped, safety facilities and sports facilities. The environmentally-friendly behaviors are positively assessed in general, but the behavior of the natural experience was negatively assessed. The environmentally-friendly behaviors in the urban parks are classified into 2 factors; the experience factor and the activity factor. The parks are categorized into 3 types by these factors. For type I parks, the experience factor is dominant, but the activity factor is relatively low. For type II parks, the both factors are low and the parks are necessary to improve. And type III parks are positively assessed in the aspect of the environmentally-friendly behaviors, even though some park are necessary to complement.

  • In women's clothing the shoulders are distorted and exaggerated. Consequently, the wearers' bodies are transformed and interpreted according to modern standards. We therefore refer to this aspect of women's clothing as the power shoulder. This study aims to analyze the differences in sensibility images on variations in the shoulder shape of power shoulder jackets. Nine samples were examined that involved combinations of three variations of the shoulder height and three variations of the shoulder width. The data was evaluated by 123 fashion design majors. Four factors were selected: attractiveness, personality, activity, and self-respect. Among these factors, attractiveness is the most important. The study results indicated that changes in shoulder height acted as a major effect that had an independent influence on all four factors. In contrast, changes in shoulder width acted as a major effect that had an independent influence on attractiveness, personality, and activity but not on self-respect. It also had an influence on the interaction effect of attractiveness, personality, activity, and self-respect. We anticipate that this study will help individual customers select clothing that is suitable for their preference and body shape because it is now possible for them to estimate images of power shoulder jackets.
