Cold start hydrocarbon is the key issue for the emission control of gasoline vehicles. The adsorber system has been studied to meet the stringent regulations with cost effective exhaust system. The key technical issues to be resolved for the practical use of the HC adsorber systems are the thermal stability of the adsorbent, the ability to adsorb major HC components from the cold exhaust system, the retention of the HC to the higher temperature, and the activation of the three way catalyst at the lower temperature. Zeolite Beta with various silica to alumina ratio have been studied for the adsorber. Low concentration of aluminum is beneficial for the stability of the zeolite. High contents of aluminum can accompany the undesired cracking of the adsorbed HC's to lighter ones which can be des orbed at the lower temperature. Steam showed the detrimental effect on the structure of the beta zeolite. High silica beta with minimal contents of alumina is favorable for the practical exhaust system with high durability. The HC adsorber catalyst system was applied for the under floor position and tested in FTP driving mode using 2.4 liter engine. The study gave the result that the HC adsorber system with lower cost can give the better performance in HC reduction than that of the conventional three way catalyst system.

본 연구는 나눠먹기식과 관행적 지원이라는 지적을 받고 있는 정부지원사업에 대한 인식(지원 내용·지원 과정·지원 공정성·지원기관 관계)과 만족도의 지원사업 효과에 대한 영향력을 지원유형(R&D·비R&D)과 기업유형(소·중·중견(대)기업) 간 비교분석하였다. 분석대상은 대구시 연구개발사업의 수혜기업 2,507개사로 하였다. 분석결과 첫째, 정부지원사업 관리의 구성요소에 대한 인식(중요도-만족도)을 실증분석하기 위한 수정 IPA 결과, 지원 내용이 중점개선영역, 지원 과정과 지원기관 관계는 과잉투자영역에 배치되었다. 둘째, 이러한 결과는 지원유형과 기업유형에 따라 다소 차이가 존재하나 모든 유형에서 지원 내용은 중점개선영역에 배치되었다. 셋째, 정부지원사업 관리의 4개 구성요소에 대한 만족도는 모두 수혜기업과 지역경제에 대한 지원효과에 유의적으로 긍정적인 영향을 미쳤고 이중 지원 내용(기간·규모)에 대한 만족도의 영향력이 가장 높게 나타났다. 넷째, 지원유형과 기업유형 간 지원사업의 효과에 대한 일부 정부지원사업 관리의 구성요소에 대한 만족도의 영향력 차이가 존재하였다. 상기 분석결과를 바탕으로 정부지원사업 효과성을 제고할 수 있는 정책적 시사점을 제시하였다. The study analyzed the perceptions of beneficiary firms about government support project by types of support and firm using revised importance-performance analysis(IPA). Also, the impact of beneficiary firms’ satisfaction on the effectiveness of the support project was analyzed by the types. The results were as follows. First, in the revised IPA results the contents of the support project was in the second quadrant(Concentrate here). The process of the support project and the relationshipwith the specialized support agency were found in the fourth quadrant(Possible overkill). Second, these results differed somewhat depending on the types, but the contents of the support project was in the second quadrant regardless of the types. Third, all satisfaction with the components of government support project management had a significant positive impact on the effectiveness of support project for beneficiary firms and the local economy. Fourth, there was a difference in the influence of satisfaction with some components on the effectiveness of the support project among the types. Based on the results, we suggested policy implications for enhancing the effectiveness of the support project

The head restraints is a safety device to protect head and neck from a car crash. Although, the rear-seat head restraints should be designed with the comfort of head as well as the clear vision of back side for driver. These goals conflict with each other because the smaller size is much better for the vision but the certain size is essential for the comfort of head. In this study, I focused on finding the factors influences to the comfort of occupants head and neck in a car by using the subjective comfort evaluation, step-wise regression analysis and correlation analysis. Furthermore, I suggest the minimum size of head restraints satisfies with key factors of comfort by analyzing the vehicles on the market.

본 연구의 목적은 미취학 자녀를 둔 여성관리자 집단의 직장-가정 전이가삶의 만족도에 미치는 영향을 검증하고, 나아가 자녀양육만족도가 직장- 가정 간 전이가 생활만족도에 영향을 미치는 관계에서 매개역할을 하는지확인하는데 목적이 있다. 이를 위해 한국여성정책연구원의 여성관리자패널5차년도 데이터를 활용하였으며 최종 분석에는 미취학자녀를 둔 여성관리자420명의 데이터가 사용되었다. 분석방법으로는 SPSS Process macro를활용한 매개효과 검증 및 부트스트래핑을 활용한 통계적 유의성 검증을 실시하였다. 주요 분석 결과로는 먼저 직장-가정 갈등은 자녀양육만족도에부정적인 영향을 미치는 것으로 나타났다. 또, 직장-가정 갈등은 여성관리자의 삶의 만족도에도 부정적인 영향을 미치는 것으로 나타났으며 자녀양육만족도는 삶의 만족도에 긍정적인 영향을 미쳤고, 직장-가정 갈등과 삶의만족도의 관계에서 부분매개효과를 가지는 것으로 나타났다. 다음으로 직장-가정 촉진은 자녀양육만족도에 긍정적인 영향을 미치고 있었으며 여성관리자의 삶의 만족도에도 긍정적인 영향을 미치는 것으로 나타났다. 또한자녀양육만족도는 직장-가정 촉진과 삶의 만족도 사이에서 부분매개효과를 가지는 것으로 나타나 직장-가정 갈등과 촉진 모두 삶의 만족도에 직접적인 영향을 미치는 동시에 자녀양육만족도를 통한 간접적인 영향을 미치고 있음이 검증되었다. 이에 따른 제언으로 첫째, 정부와 기업조직은 여성관리자들이 직장과 가정 생활을 양립할 수 있도록 제도적 장치와 조직문화를 마련할 필요가 있으며 특히 노동시간을 감소시킬 수 있는 방안을 마련해야 한다. 둘째, 여성의 일을 인정하는 문화와 법적제도를 만듦으로써직장-가정 촉진을 향상시키고 자녀양육과 삶의 만족에 긍정적인 기여를해야 한다. 셋째, 정부에서는 여성근로자들의 욕구를 충족시키고 자녀돌봄의만족도를 높일 수 있는 육아지원정책을 마련해야 한다. 이러한 결론을 토대로 본 연구의 의의와 제한점, 그리고 후속연구를 위한 제언을 서술하였다. The purpose of this study was to examine the impact of Work - Family Spillover on the Life Satisfaction of women managers with preschool children, and furthermore, to investigate whether the Child - Rearing Satisfaction plays a mediating role in the relationship between Work - Family Spillover and Life Satisfaction. For this purpose,, data from the 5th year of the Korean Women Managers Panel of the Korea Women s Development Institute was used. In the final analysis, data of 420 female managers with preschool children were used. As the analysis method, we performed the Mediating effect verification using SPSS Process Macro and statistical significance test using Bootstrapping. Key Findings are as follows: First, Work-Family Conflict has a negative effect on child rearing satisfaction. Second, Work-Family Conflict negatively affects the life satisfaction of women managers. Third, Child Rearing Satisfaction had a positive effect on life satisfaction and partial mediation effect on the relationship between Work- Family Conflict and Life Satisfaction. While, Work- Family promotion had almost same impact on life satisfaction as well as child rearing satisfaction, although derection was oppoesed. Based on these results, following suggestions are insisted. First, government and corporate organizations need to establish institutional devices and organizational culture to enable women managers to reconcile their workplace and family, and in particular to create ways to reduce working hours. Second, creating a culture and legal system to recognize women s work can improve work-family facilitation and positively contribute to child care and life satisfaction. Third, the government should provide childcare support policies that meet the needs of female workers and raise the satisfaction of child care. Based on these conclusions, we described the implications and limitations of this study, and suggestions for future research.

It was conducted to evaluate the control efficacy of Bordeaux mixture on pepper anthracnose in vitro and in vivo. The suppressive efficacy of Bordeaux mixture on mycelial growth and spore germination of Colletotrichum acutatum was investigated on PDA, cellophane membranes and pepper fruits, respectively. Furthermore, its control value was evaluated on detached pepper fruits inoculated with C. acutatum by wound and non-wound inoculation method, and in fields. The mycelial growth of C. acutatum JC24 was inhibited by 90.0% on PDA amended with 937 μg mL?1 of Bordeaux mixture. While the spore germination of C. acutatum JC24 was inhibited perfectly on cellophane membranes treated at 187 μg mL<SUP>?1</SUP> of Bordeaux mixture, that on fruits inoculated with the pathogen by wound inoculation and non-wound inoculation method was inhibited by 88.1% and 91.3%, respectively. Although the control value on fruits treated with 937 μg mL<SUP>?1</SUP> of Bordeaux mixture was 17.6% in wound inoculation method, it was 58.8% in non-wound inoculation method. In fields, when Bordeaux mixture was sprayed five times at 14 day-intervals, it showed 55.7% and 61.7% of control value in 2012 and 2013, respectively. We think Bordeaux mixture was able to use as an eco-friendly organic farming material to control pepper anthracnose based on the above-mentioned results.
