Treatment with low-dose follicle-stimulating hormone and laparoscopic laser vaporization is associated with a high rate of ovulation in anovulatory women with polycystic ovarian syndrome (PCOS), but it is not clear which is better. We undertook a randomized controlled study to compare the effects of urinary FSH and hMG using a low dose regimen and laparoscopic laser vaporization of ovaries in sixty women with PCOS. Ovulation occured in 65% subjects and in 71.1% of cycles induced with FSH and in 70% of women and 76% of cycles of those treated with hMG and in 80% of women in laparoscopic laser vaporization of ovaries. A single dominant follicle developed in 62.2% (FSH) and 60% (hMG) of cycles, respectively. Eight singleton pregnancies occured in FSH, hMG group and 12 singleton pregnancies occured in laparoscopic laser vaporization. This study shows that selected patients with PCOS and by induced to ovulate and subsequently conceive by laparoscopically partially vaporizing their ovaries with laser energy.

본 연구는 직무자율성이 자기효능감과 조직시민행동에 미치는 영향과 자기효능감의 매개작용을 연구했다. 연구목적을 달성하기 위해 직접판매회사에 종사하는 판매원 183명의 응답을 표본으로 SPSS 12.0와 AMOS 5.0을 이용하여 검증되었다. 연구결과, 직무자율성은 자기효능감과 조직시민행동에 정(+)의 영향을 미쳤으며, 자기효능감은 직무자율성과 조직시민행동 간에 부분매개작용을 하였다. 연구결과를 바탕으로 시사점과 연구의 한계점 및 향후 연구방향을 제시하였다. The purpose of this study is to examine the effects of job autonomy on self-efficacy and organizational citizenship behavior. In order to verify the relationship, data obtained from 183 salesman worked in Ulsan Metropolitan City were analyzed by using SPSS 12.0 and AMOS 5.0. The findings are as follows: First, the relationship between job autonomy and self-efficacy is positively related. Second, the relationship between job autonomy and organizational citizenship behavior is positively related. Third, there was also a positive correlation between self-efficacy and organizational citizenship behavior. Finally, self-efficacy played as a partial mediator on the relationship between job autonomy and organizational citizenship behavior.

저자들은 류마티스관절염에서 TNF-α 억제제 치료 후에 비장 결핵이 발생한 64세 여자 환자를 진단하고 치료하였으며, 결핵 치료 도중 악화된 류마티스관절염에 대하여 결핵의 악화 없이 rituximab으로 치료한 경험을 하였기에 이에 보고하는 바이다. One of the most important adverse effects of a tumor necrosis factor (TNF)-α inhibitor is the reactivation of tuberculosis. Most of them occur in the lung, but sometimes they can be found in other organs. Moreover, the proper management of active rheumatoid arthritis (RA) in patients with anti-TNF-α associated tuberculosis is still in debate. We present the case of a seropositive RA patient who showed good response with rituximab, an anti-CD20 monoclonal antibody, after developing splenic tuberuculosis, following treatment with TNF-α inhibitor. Confirming a diagnosis of splenic tuberculosis is difficult and can be delayed due to its nonspecific symptoms and rare occurrence. This case suggests that splenic tuberculosis should be doubted in RA patients treated with TNF-α inhibitor, and that rituximab may be considered as an alternative treatment option in RA patients with anti-TNF-α associated tuberculosis.

손은일(Eun-Il Son),송정수(Jung-Su Song) 한국산업경제학회 2012 산업경제연구 Vol.25 No.6

본 연구는 종사원의 심리적 자본이 사회적 지지와 심리적 안녕감에 어떠한 영향을 미치는지와 심리적 자본과 심리적 안녕감 간의 관계에서 사회적 지지가 매개작용을 하는지를 파악하여 기업이 나아가야 할 방향을 제시하였다. 연구목적을 달성하기 위해 창원시의 제조업 종사자 275명의 응답을 표본으로 SPSS 12.0과 AMOS 5.0을 이용하여 검증되었다. 연구결과, 심리적 자본은 사회적 지지와 심리적 안녕감 각각에 정(+)의 영향을 미쳤으며, 사회적 지지도 심리적 안녕감에 정(+)의 영향을 미쳤다. 그리고 사회적 지지는 심리적 자본과 심리적 안녕감 간의 관계에 있어서 부분 매개작용을 하였다. 본 연구는 심리적 자본에 대한 이론을 보완하고 확장하였으며, 동시에 조직구성원들의 심리적 안녕감을 높이기 위한 새로운 모델을 제시하였다. 또한 실무적으로, 기업은 조직구성원의 심리적 안녕감을 제고하기 위해 개인의 심리적 자본을 개발하고 관리하며 사회적 지지를 증가시켜야 함을 시사한다. 연구결과를 바탕으로 연구의 한계점 및 향후 연구방향을 제시하였다. This study had two purposes. The first purpose was to examine the effect of psychological capital on social support and psychological well-being. The second purpose was to examine mediating effect of the social support between psychological capital and psychological well-being. For the study, the data was collected from convenient sample of 275 employees working in firms at Changwon City. The research was conducted by using SPSS 12.0. and AMOS 5.0. The results of the study are as follows: First, psychological capital positively affects social support. Second, social support positively affects psychological well-being. Third, psychological capital positively affects psychological well-being. Finally, the social support was a partial mediating effect on the relationship between psychological capital and psychological well-being. This study contributes to our understanding of psychological capital and psychological well-being research by suggesting an alternative analytical model, highlighting the role of psychological capital and social support. This study suggests that developing the psychological capital of employees in a organization and effective social support system are required for better psychological well-being. Based on these findings, the limitations of the study and some directions for future studies were presented.

이규용(Kyu-Yong Lee),송정수(Jung-Su Song) 한국콘텐츠학회 2021 한국콘텐츠학회논문지 Vol.21 No.3

본 연구에서는 임파워링 리더십이 내재적 동기, 잡 크래프팅, 직무성과에 미치는 영향을 살펴보았다. 그리고 임파워링 리더십과 직무성과의 관계에 있어서 내재적 동기와 잡 크래프팅의 매개역할을 검증하였다. 양산, 울산, 경주의 중소기업 종사자로부터 수집한 설문자료를 사용하여 연구가설을 검증하기 위한 공분산 구조분석을 하였다. 연구결과 첫째, 임파워링 리더십은 내재적 동기, 잡 크래프팅에 유의한 영향을 미치는 것으로 나타났다. 둘째, 임파워링 리더십은 직무성과에 유의한 영향을 미치지 않는 것으로 나타났다. 셋째, 내재적 동기는 잡 크래프팅에 유의한 영향을 미치는 것으로 나타났지만 직무성과에는 유의한 영향을 미치지 않는 것으로 나타났다. 넷째, 잡 크래프팅은 직무성과에 유의한 영향을 미치는 것으로 나타났다. 끝으로 임파워링 리더십과 잡 크래프팅 간의 관계에서 내재적 동기가 부분 매개역할을 하는 것으로 나타났다. 임파워링 리더십과 직무성과 사이에 잡 크래프팅이 완전 매개역할을 하는 것으로 나타났다. 본 연구 결과에 의하면 조직구성원의 직무성과 향상을 위해 리더의 임파워링 리더십을 통한 내재적 동기와 잡 크래프팅을 강화시켜야 함을 시사하고 있다. In this study, we investigated the impact of empowering leadership on intrinsic motivation, job crafting, and job performance. The role of intrinsic motivation and job crafting in the relationship between empowering leadership and job performance was verified. Covariance structure analysis was conducted to verify the research hypothesis using questionnaire data collected from SME workers in Yangsan, Ulsan, and Gyeongju. The results were as follows. First, empowering leadership has a significant influence on intrinsic motivation, job crafting. Second, empowering leadership did not have a significant influence on job performance. Third, intrinsic motivation has a significant influence on job crafting but intrinsic motivation did not have a significant influence on job performance. Fourth, job crafting has a significant influence on job performance. Finally, intrinsic motivation plays a partial mediating role in the relationship between empowering leadership and job crafting. job crafting plays a full mediating role in the relationship between empowering leadership and job performance. The results of this study suggest that employees intrinsic motivation and job crafting should be promoted through the leaders empowering leadership in order to improve job performance.

Due to the limitations of Moores Law, scaling down components in traditional CMOS processing and von Neumann architecture has gradually approached its constraints. Notably, Neuromorphic computing technology, which seeks to emulate the human brain, has gained significant attention. In this study, we have fabricated a two-terminal device which is based on Hf0.5Zr0.5O2 (HZO) thin films and is known as a Ferroelectric Tunnel Junction (FTJ). After device fabrication, we conducted P-V and I-V measurements to assess ferroelectric and memory properties. Then we evaluated the crystalline structure of HZO thin films through XRD analysis. Finally, we successfully implemented Synaptic Functions by applying pulse input.
