This study focused on adolescents who are studying in middle schools of the Gyeongnam region, aims to provide methods for improving school adjustment among adolescents through the enhancement of family strength. It will examine the effect of family strength on adolescents' school adjustment verify the mediating effect of social support in the influential relationships of school adjustment. The summarizations, obtained in this study are as follows: First, an analysis of the results of the effect of family strength on social support demonstrated that family strength had a positive effect on social support. That is, as family strength was higher, social support increased. Second, an analysis of the results of the effect of family strength on school adjustment show that family strength would have a direct effect on school adjustment, which is positive. Where family strength was higher, school adjustment of adolescents was also higher. Third, the results of the effect of social support on school adjustment when controlling family strength demonstrate that social support would have a positive effect on school adjustment, however, family strength did not predict school adjustment. Therefore, the complete mediating effect of social support in the relationship between family strength and school adjustment was identified. In conclusion, it was identified that family strength had an indirect effect on school adjustment, but not a direct effect. Therefore, it is indicated that indirect intervention through the social support system as well as direct intervention for the improvement of adolescents' school adjustment is required. In addition, it was confirmed that family strength and social support would be more important variables than control variables, which reflect the characteristics of adolescents and family in terms of school adjustment. Therefore, the recognition that the responsibility in adjusting to school is the common role of families, schools, and community going beyond the individual responsibility of adolescents is needed.

본 연구는 남녀 성별 성격 특성단어에 대한 정서판단시에 개입되는 자동적 평가효과를 점화과제를 통해서 검증하였다. 점화조건과 목표조건에 따라 성격 특성단어들을 네 가지로 조합하였으며 두 가지 유형의 SOA에서 점화단어와 목표단어에 대한 일치성 효과와 긍정성 우위 효과를 살펴보았다. 실험1의 짧은 SOA(150­250ms)에서는 긍정-긍정 단어쌍이 부정-부정 단어쌍보다 반응시간이 빠르게 나타났다. 실험 2의 긴 SOA(500­1000ms)에서는 단어쌍 조건간에 차이가 나타나지 않았다. 즉, 짧은 SOA에서는 긍정성 우위 효과가 나타났지만, SOA가 길어짐에 따라서 일치성 효과나 긍정성 우위 효과는 모두 유의미하지 않았다. 이러한 결과는 사회인지적 대상에 대한 자동평가가 일반 인지체계에서 일관되게 나타나는 자동적 의미처리과정과는 다를 수 있음을 시사한 것으로 볼 수 있다. 편견이나 고정관념처럼 정서가 내포된 사회적 정보는 정서의 긍정성이나 부정성에 따라서 다른 처리가 일어날 수 있다고 본다.

When evaluating effectiveness of a R&D program, there is a tendency to simply compare the performances of the beneficiaries before and after the program or to compare the differences in the performances of the beneficiaries and the non-beneficiaries before-after the program. However, these ways of evaluating effectiveness of a program have some problems because they can not differentiate between complement effect, which facilitates corporate R&D investment, and substitute effect, which, literally, substitutes corporate R&D investment. Therefore, these problems could bring about wrong policies concerning R&D programs. In this paper, a new approach using path analysis is suggested as a means to overcome these problems and it is utilized, as an application, to evaluate the effectiveness of Plant Engineering Program conducted by Ministry of Trade, Industry & Energy, Korea. First, the direct impact of government R&D investment on corporate R&D investment is analyzed, through which it is identified which of crowding-in effect (complement effect) and crowding-out effect (substitute effect) is dominant. Next, the direct effect of government R&D investment on corporate performance and the direct effect of corporate R&D investment on corporate performance is analyzed respectively. Finally, by combining the two previous analysis, the total effect of government R&D investment on corporate performance is identified. As a result, it turns out that, in Plant Engineering Program, crowding-in effect is more dominant than crowding-out effect and that Plant Engineering Program has definitely positive effect on the beneficiary in terms of corporate performance indirectly and directly.

This study performed factor analysis for 21 independent variables related to the effect of illumination and suggested the effect by multiple regression analysis on the relationship between the effect of illumination and the satisfaction of use of a dependent variable to find the effect of illumination in urban parks at night and the effect of illumination on the satisfaction of use. The results of this study are as follows; 1) Of the 21 independent variables used to study the effect of illumination in urban parks at night, the impact on safety and possibility of crime was highly. The effects of illumination by factor analysis were abstracted as effects of removing anxiety, securing safety, increasing use. 2) As a result of multiple regression analysis, independent variables influencing satisfaction of use in urban park were proved as effects of removing anxiety, securing safety, increasing identity, preparing atmosphere and increasing use. Also, the effect of securing safety was the most important factor; it showed a level of importance 2 times higher than the effect of removing anxiety, and 7.7 times higher than the effect of preparing atmosphere in relative contribution of the effect of illumination to satisfaction of use. 3) Of the effects of illumination influencing satisfaction of use in urban parks, the effect of securing safety and the effect of increasing visibility were more significant than the effects of removing anxiety, preparing atmosphere and increasing use. This fact means that personal safety an the identity of persons or facilities in the space of use should be considered with priority in planning or designing illumination. Also, it implies hat, for night use in urban parks, lightness of the space is required for general safety of use at parks, and proper illuminance on the activity in the space of use should be required. The subject parks of this study are 8 urban neighborhood parks. The model on the effect of illumination and the satisfaction of use depends on characteristics and conditions of location of he park and user class, so the subject parks and persons should be varied, and the difference by sex or ages should be suggested.

Water and energy are inextricably linked and referred to as 'Water-Energy Nexus'. Recently, this topic has been drawing a lot of attention from various studies due to the exacerbated water availability. Korea's water and energy consumption has been increasing consistently, which calls for better management. This paper aims to identify changes in electricity consumption in relation to water intake and purification processes. Using Log Mean Divisia Index (LMDI) Decomposition Analysis method, this study attributes the changes to major factors such as; Total population (population effect), household/population (structure effect), GDP/household (economic effect), and water-related energy use/GDP (unit effect). The population effect, structure effect, and economic effect contributed to an increase in water-related electricity consumption, while the unit effect contributed to a decrease. As of 2019, the economic effect increased the water supply sector's electricity consumption by 534 GWh, the population effect increased by 73 GWh, and the structure effect increased by 243 GWh. In contrast, the unit effect decreased the electricity consumption by -461 GWh. We would like to make the following suggestions based on the findings of this study; first, the unit effect must be improved by increasing the energy efficiency of water intake and purification plants and installing renewable energy power generation facilities. Second, the structure effect is expected to increase over time, and to mitigate it, water consumption must be reduced through water conservation policies and the improvement of water facilities. Finally, the findings of this study are expected to be used as foundational data for integrated water and energy management.

Purpose : In this study, to prove the antibacterial effect of Disocorea batatas, which is widely used for food, and to confirm the growth inhibitory effect, the antibacterial activity against L. gasseri, S. mutans, and P. gingivalis was verified. Based on this, it is intended to verify the utility as a preventive and therapeutic composition for dental caries and periodontal disease. Methods : RAW 264.7 cells were used to verify the cell survival rate and NO (Nitric Oxide) inhibitory effect on Disocorea batatas ethanol extract (DBEE). In order to verify the antibacterial effect against L. gasseri, S. mutans, and P. gingivalis, concentrations of 125, 250, and 500 ㎎/㎖ of DBEE were used and measured by the disk diffusion method. In order to confirm the growth inhibitory effect, the absorbance was measured at 600 ㎚ at 3, 6, 12, 18, and 24 hours using the liquid medium dilution method, and the growth inhibitory effect was measured compared to the control group. Results : The cell viability for DBEE was 91 % at 50 ㎎/㎖, and there was no cytotoxicity. The NO production inhibitory effect was shown from 10 ㎍/ml, and the higher the concentration, the greater the inhibitory effect. As for the antimicrobial effect using the disk diffusion method, the higher the concentration, the higher the antibacterial effect. At 125 ㎎/㎖ and 250 ㎎/㎖, S. mutans and L. gasseri showed high antimicrobial activity, and at 500 ㎎/㎖, the antibacterial effect was higher in L. gasseri. The growth inhibitory effect in DBEE was concentration-dependent as the higher the concentration, the higher the growth inhibitory effect, and all of them began to show growth inhibitory effects from 6 hours. Conclusion : Considering that it is widely used as an edible and medicinal material, Disocorea batatas has shown the potential to be used as a substance to prevent and alleviate dental caries and periodontal diseases, and it is believed that further research can be applied to oral health care products.
