This study uses data from the 11th year(2016) to the 15th year(2020) of the Korea Welfare Panel(KOWEPS) for the five years that the survey was completed to predict the life satisfaction of each individual by generation, centered on single-person households. This is a longitudinal analysis using a latent growth model. The generational division was based on the turning point of a major event experienced by the cohort that brought about a decisive change in the socialization process, historical event, and technological development as factors. The analysis data used in this study were of 27,447 persons in the 15th year of the Korea Welfare Panel(2020), 2,778 persons who were single-person households even in the first year from the last 5 years, and 1,448 persons who were single-person households continuously for 5 years. Excluding those born in 1922 to 1944(843 persons), 605 persons born between 1945 and 1996 were included. As a result of the study, Generation Y(millennials) than Generation X(new generation) and Generation X generation than Baby Boomers showed higher overall life satisfaction. Since overall life satisfaction by generation does not have an effect on the rate of change, it was found that this difference remains the same for all generations.

본 연구는 창업보육센터 입주기업을 대상으로 지원서비스가 성장단계별로 차이가 있을 것이라는 가정과 입주기업이 느끼는 만족도와 그에 따른 경영성과에 영향을 미칠 것이라는 가정 하에 입주기업의 니즈(needs)를 반영한 성장단계별 차별화된 효과적 지원서비스로 입주기업의 만족도와 경영성과를 높임으로써 창업성공률을 제고하기 위한 이론적 기여와 정책적 시사점을 제시하는 데 목적이 있다. 본 연구의 검증을 위하여 가설1 성장단계별 지원서비스는 정(+)의 유의한 차이가 있을 것이다, 가설2 성장단계별 만족도는 정(+)의 유의한 차이가 있을 것이다, 가설3 성장단계별 경영성과는 정(+)의 유의한 차이가 있을 것이다를 ANOVA 분석을 실시하였고, 가설4 지원서비스가 경영성과에 정(+)의 영향을 미칠 것이다, 가설5 지원서비스가 만족도에 정(+)의 영향을 미칠 것이다, 가설6 만족도가 경영성과에 정(+)의 영향을 미칠 것이다는 회귀분석을 실시하였다. 분석결과, 선행연구와 같이 지원서비스는 입주기업의 경영성과와 만족도에 영향을 미치는 것으로 나타났다. 본 연구는 창업보육센터의 성장단계별 지원서비스가 서비스의 만족도와 경영성과에 어떠한 영향을 미치고 있는지를 중소기업청 지정 창업보육센터 입주기업 174개를 표본으로 SPSS 22.0을 이용하여 검증하였다. 본 연구에서 실증분석을 통하여 얻은 연구 결과를 요약하면 다음과 같다. 첫째 성장단계별 지원서비스의 차이에 대한 차이분석 결과 정(+)의 유의한 차이가 있는 것으로 나타났다. 둘째, 성장단계별 만족도의 차이는 차이가 없는 것으로 나타났으며 성장단계별 경영성과의 차이 중 투자유치는 정(+)의 유의한 차이가 있는 것으로 나타났다. 셋째, 창업보육센터에서 제공하는 지원서비스가 입주기업의 경영성과와 만족도에 정(+)의 영향을 미치는 것으로 나타났다. 마지막으로 입주기업의 만족도도 경영성과에 정(+)의 영향을 미치는 것으로 나타났다. 결과를 종합해보면 창업보육센터의 지원서비스가 아직도 행정지원과 자금지원 등에만 국한되어 지원되고 있는 것으로 나타나 입주기업의 성장단계에 적합한 다양한 서비스의 제공이 필요함을 주지시켜 주고 있다. 또한, 성장단계별 입주기업의 만족도는 매출증가와 고용증가로 이어졌지만 아직 투자유치에는 크게 영향을 미치지 못하고 있음을 알 수 있다. 따라서 모든 입주기업에게 획일적인 지원서비스가 아닌 차별화된 지원서비스가 필요하며, 이를 위하여 창업보육센터 매니저들이 엑셀러레이터로서의 역할을 하기 위한 창업보육역량 고도화가 필요하고, 창업보육사업은 기업의 성장단계와 관련이 있으므로 입주기업의 성장단계 및 창업보육센터의 지원하는 역할과 기능에 따른 창업보육모델의 진화를 고려한 3세대, 4세대 보육모델로서의 발전된 운영정책 수립이 요구된다.

This study demonstrates a variability in efficacy of mating disruption against the oriental fruit moth, Grapholita molesta, populations infesting apples cultivated in differential environmental conditions. Throughout the growing seasons, trap catches of G. molesta male moths and damaged leaf and fruit were examined to evaluate the efficacy of a commercialized mating disruptor. Treatment of the mating disruptor significantly reduced the trap catches of male moth in treated plot, compared to those of the untreated plot. This reduced trap catches were significantly correlated with leaf and fruit damage. Moreover, the highest host damage occurred in June just after the highest overwintering adult peaks in both plots. The treatment of mating disruptors in Chungsong effectively disrupted the overwintering population in April and May, resulting in no noticeable host damage during the following growing seasons. However, there was a marked difference in host damage between two plots, especially in late seasons. Variation in the efficacy of mating disruption technology in terms of host damage appeared to be related with nearby pheromone-untreated orchards, which may result in the immigration of gravid females.

This study was carried out to compare on the time of occurrence of 6 major rice insect pests [Lissorhoptrus oryzophilus Kusche, Oulema oryzae Kuwayama, Sogatella furcifera (Horvath), Nilaparvata lugens Stal., Cnaphalocrocis medinalis (Guenee), Mythimna separata Walker] in northern part of the Korean peninsula. Using growing degree days of the insects, we evaluated the number of occurrence generations and the time of occurrence. Over-wintering insects such as L. oryzophilus and O. oryzae showed different occurrence periods in northern regions. The occurrence period of the first generation adults was later in northeast regions than in Korean middle regions and more later both in northern alpines and in northern parts of east sea. In addition, the first adults of S. furcifera, N. lugens, C. medinalis, and M. separata occurred between June and early August. However, from late August to September, these insects showed the different occurrence periods in northern regions. Especially, the second adults of N. lugens were not occurred and the second to third generation adults of S. furcifera, C. medinalis, and M. separata showed similar occurrence properties. Based on these properties, the occurrence of major rice insect pests will be less in northeast regions, northern regions of east sea, northern inlands, and northern alpines of the Korean peninsula. However, comparing with their occurrences in northern regions of Gyenonggi and Gangwon provinces, the rice insect pests may show similar occurrence pattern in mid-korean mountains except for pyunggang and yangduk regions as well as in the southern and northern regions of Suyang-san.
