In vitro cultrue systems for the growth of sma-II oocytes and for meiotic maturation are expected to provide a new source of a large population of oocytes as well as assistance in basic physiological studies of oogenesis. Mouse oocytes mid-growth phase can complete grovvth and acquire full developmental capacity in vitro. On the other hand, growing pig oocytes need some other factors. FSH at a low concentration maintains the viability of both oocytes and granulosa cells, and hypoxanthine promotes the meiotic competence of the oocytes during culture period. Considerable improvement in the culture systems for growth of pig oocytes, suggested from mouse studies, and for oocyte maturation could help to develop this technology in larger species.

어플리케이션에 대해 사용한 후 비용을 지불하는 use first, pay later 서비스 개념의 SaaS의 구현 성숙도 모델이 Microsoft 사, Dharmesh Shah, Forrester 사에서 정리되어 발표되었다. 하지만 기존의 SaaS 성숙도 모델은 SaaS 생태계에 존재하는 이해당사자들의 관점 중 서비스 제공자의 관점만 반영되어 SaaS 어플리케이션 사용자, 개발자, 테넌트 관리자의 측면에서 고려된 기술 성숙 방향이 반영되어 있지 않다. 본 논문은 SaaS 기본 이론과 업계 제품에서 조사된 이론에 입각해 SaaS 생태계 전반의 SaaS 이해당사자들 관점에서 SaaS 플랫폼 역량의 발전을 분류할 수 있는 체계를 아키텍처에 기반하여 제시하고자 한다.

This study analyzed the correlation of work values, career attitude maturity and employment preparation behavior by determining the sociodemographic characteristics, and the study confirmed the validity of the influence of work values and career attitude maturity on employment preparation behavior. The subjects of this study were 218 nursing students at a university located in Geonggi-do. The data was collected from June 4th to August 27th, 2019 by using structured questionnaires. As a result, female students scored significantly higher in work values and career attitude maturity than did the male students, and the students who had better grades showed higher employment preparation behavior. In addition, the result showed positive correlation between work values and employment preparation behavior, and the study showed correlation between career attitude maturity and employment preparation behavior. Greater independence, readiness, certainty, and decisiveness were higher and were sub-factors of career attitude maturity and employment preparation behavior. Moreover, the higher the students' patriotism and indoor activities, the higher was their employment preparation behavior. In conclusion, the employment preparation behavior was higher according to greater work values, while the influence of career attitude maturity on employment preparation behavior was not statistically significant.

The purpose of this study is to identify relationships among psycho-social maturity, self-efficacy for contraceptive, and sexual assertiveness to see which factors influence sexual assertiveness in male university students. Data were collected from 200 male university students in A city from July 1 to 30, 2015. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Significant correlations were found among Psycho-Social Maturity, Self-efficacy for Contraceptive, and Sexual Assertiveness. Meaningful variables that influenced Sexual Assertiveness were Self-efficacy for Contraceptive and Psycho-Social Maturity, and the total explanation power was 33%. In conclusion, development of sex education program to increase Sexual Assertiveness of male university students based on the influencing factors is needed.

The purpose of this study is to identify the relationships among Ego-Resilience and Psycho-Social Maturity, Stress Coping Styles, and influencing factors on Stress Coping Styles of university students. Data were collected from 200 male university students in A city from June 1 to 30, 2016. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. Significant correlations were found among Ego-Resilience and Psycho-Social Maturity, Stress Coping Styles. Meaningful variables that influenced Stress Coping Styles were Ego-Resilience and Psycho-Social Maturity, grade, and the total explanation power was 38%. In conclusion, development of Stress Coping Styles program to decrease the stress of university students based on the convergent influencing factors is needed, and further development of scale for Stress Coping Styles for the university students in Korea based on the related factors is also needed.

나노분말 기술은 나노기술이 성숙단계에 접어들 것으로 예상되는 2012년 내지 2015년경에 성숙될 기술이 아니라 이미 산업화가 빠른 속도로 이루어지고 있으며 나노기술의 산업화를 선도할 기술이다. 나노분말 기술은 에너지/환경은 물론 IT, BT 산업 등 거의 모든 신산업 분야에 활용되고 있거나 활용될 전망이다. 이러한 이유로 거의 모든 국가들이 수행하고 있는 나노기술개발 프로그램에 나노소재 기술이 중요한 분야로 다루어지고 있고 나노분말 소재기술 분야는 빠지지 않는 기술 분야이다. 우리나라의 나노기술개발 프로그램에서도 예외는 아니다. 많은 수의 연구과제들이 수행되고 있으며 일부 상업화에 접어든 기술들도 있다. 미국, 일본 등 거의 모든 나라에서 다수의 벤처기업들이 나노분말 기술의 상업화에 뛰어들고 있다. EU의 경우는 전체 나노소재 관련 사업체 중 절반에 해당하는 업체들이 나노분말 업체라는 점은 눈여겨 볼만하다. 앞서 살펴보았듯이 나노분말 기술은 그 자체가 하나의 산업을 이끌어낼 기술인 동시에 기존산업을 포함한 소재산업은 물론 나노기술 산업을 바탕으로부터 지탱해줄 기반기술이다. 그만큼 많은 가능성을 갖고 있으며 기술적인 장애가 하나씩 극복될 때마다 기술의 발전속도는 빨라질 것이며 시장 또한 빠르게 확대될 것이다.

To develop large-scale complex systems, many organizations have attempted to improve the processes specified in systems engineering (SE) and project management (PM) by adopting CMMI (Capability Maturity Model Integration). On the other hand, most domestic organizations that already acquired CMMI level 3 have focused on SE&PM practices while providing less investment in building up the environment for institutionalizing those processes. In such organizations, the process maturity without advancing to institutionalization can be neither enhanced nor maintained. To resolve the problem, the following remedies can be suggested. A standard process should first be defined to meet the business mission of the organization and to carry out the process successfully, the people should be properly trained and the appropriate tools be provided. In this study, a maturity model to accomplish institutionalization was examined based on the aforementioned P-P-T (Process-People-Tool) concept. The model proposed would be useful in developing strategies and plans for process institutionalization when the organizations are in the preparation stages for a CMMI certificate or have already acquired one.

This study investigated the effects of goat blood serum (gBS), goat follicular fluid (gFF) and gonadotropin (FSH) on the in vitro maturation, fertilization and development of Korean native black goat oocytes. Our results indicate that the gBS combined with FSH treated group showed significantly higher maturation rate than the other groups. Furthermore, blastocyst formation rate was significantly increased in all treated groups, and gBS and gFF combined with FSH treated groups were higher than other groups. However, gene expression levels of BMP15 and GDF9 in COC, both oocyte maturation related genes, remained unaffected after 24 h maturation. The results of the present study indicate that supplementation of the maturation medium with gBS, gFF and FSH is efficacious in improving the in vitro maturation, fertilization and development of Korea native black goat oocytes.
