조직 갈등이 경력변경의도에 미치는 영향: 역할 스트레스의 매개효과와 성장욕구의 조절된 매개효과
서승호,김정원 한국인력개발학회 2022 HRD연구 Vol.24 No.1
This study was aimed to identify the mediating effect of role stress and the moderating effect of growth needs in the relationship between organizational conflict and career withdrawal intention. For this study, the data from a total of 304 in Seoul area were selected for analysis in the study, and exploratory factor analysis, reliability verification, basic statistics, and correlation analysis were conducted using the SPSS 23.0 program. In addition, the moderated mediating effect was examined using model 15 of PROCESS macro, and the bootstrapping method was used for the statistical verification of the conditional indirect effect and the controlled mediating index. The results of the study are as follows. First, there was a mediating effect of role stress in the relationship between organizational conflict and career withdrawal intention. Second, the moderating effect of growth desire was identified in the relationship between organizational conflict and career withdrawal intention, and it was found that the moderating effect was large when growth desire was low. Third, growth needs moderated the influence of relationship between organizational conflict and career withdrawal intention through role stress. For practical implications, it was suggested that organizational support is necessary to lower members' organizational conflicts and career withdrawal intentions and provide various education and opportunities to participate in projects and programs to meet members' growth needs. Finally, it is significant to create an organizational culture in which members can grow together internally. 본 연구에서는 조직 갈등과 경력변경의도의 관계에서 역할 스트레스의 매개효과와 성장욕구의 조절효과를 검증하고자 하였다. 이에 서울 지역 총 304명의 데이터를 분석 대상으로 선정하였으며, SPSS 23.0 프로그램을 활용하여 탐색적 요인분석, 신뢰도 검증, 기초통계 및 상관분석을 진행하였다. 또한 PROCESS macro의 model 15를 이용해 조절된 매개효과를 검증하였으며, 조건부 간접효과와 조절된 매개지수의 통계적 검증은 부트스트래핑 방법을 사용하였다. 연구 결과, 첫째, 조직 갈등과 경력변경의도의 영향 관계에서 역할 스트레스의 매개효과가 있음을 확인하였다. 둘째, 조직 갈등과 경력변경의도의 관계에서 성장욕구의 조절효과가 나타났으며, 성장욕구가 낮은 경우의 조절효과가 큰 것으로 나타났다. 셋째, 성장욕구는 역할 스트레스를 통해 조직 갈등이 경력변경의도에 미치는 영향 관계를 조절하는 것으로 나타났다. 이러한 연구 결과를 바탕으로 실무적 측면에서는 구성원의 조직 갈등과 경력변경의도를 낮추기 위한 조직 차원의 지원이 필요하며, 다양한 교육과 프로젝트 참여 기회를 제공하는 것뿐만 아니라 조직 내부적으로 구성원이 동반 성장할 수 있는 조직문화를 조성해야 한다는 시사점을 도출하였다.
Selection of Optimal Lower Instrumented Vertebra for Adolescent Idiopathic Scoliosis Surgery
서승호,현승재,이재구,조용재,조대진,박진훈,김기정 대한척추신경외과학회 2023 Neurospine Vol.20 No.3
Adolescent idiopathic scoliosis (AIS) affects approximately 2% of adolescents across all ethnicities. The objectives of surgery for AIS are to halt curve progression, correct the deformity in 3 dimensions, and preserve as many mobile spinal segments as possible, avoiding junctional complications. Despite ongoing development in algorithms and classification systems for the surgical treatment of AIS, there is still considerable debate about selecting the appropriate fusion level. In this study, we review the literature on fusion selection and present current concepts regarding the lower instrumented vertebra in the selection of the fusion level for AIS surgery.

We researched about a bulk metallic glass system as an additive to an Ag paste for high temperature thermoelectric modules. Bulk metallic glass (BMG) ribbons were produced by using a rapid solidification process (RSP) under a cooling rate condition higher than $10^{\circ}C/sec$. We investigated BMG characteristics of the ribbons by means of x-ray diffraction (XRD) and differential scanning calorimetry (DSC) in order to evaluate the glass transition temperature ($T_g$) and the recrystallization temperature ($T_x$) lower than $400^{\circ}C$. A milling process was also developed to apply the BMG ribbons to a commercial Al paste as an additive for lower sintering temperature.
Alloxan Diabetes 및 膵管結紮이 Cholesterol 食餌性 家兎動脈硬化症에 미치는 影響
徐承昊 中央醫學社 1967 中央醫學 Vol.13 No.2
Dragstedt (1945) and Best (1948) drew attention on the significant role of the pancreas in atherogenesis through its endocrine and exocrine secretion. Clawson and Bell (1949), Dolger (1950) and Bell (1952) found higher incidence of arteriosclerosis, peripheral gangrene, coronary diseases, and vascular diseases of the kidney among diabetics than non-diabetics based on the study of autopsy materials. Bevans (1955) stated that arteriosclerosis in diabetics involves principally the arteries of medium and small size, and LeCompte (1955) stated that sclerotic process involves also capillaries and venules characterized by deposition of hyaline substance rich in polysaccharides in the wall. In 1958 Goldenberg et al. found high incidence of non-atheromatous sclerosis of small branches of the coronary arteries in diabetic patients, and they interpreted the changes as the result of hypertension which is frequently associated with diabetes. Goldenberg et al. (1959) and Alex et al. (1959) reported that the non-atheromatous sclerosis started with swelling of endothelial cells followed by proliferation of endothelial cells and deposition of colloidal-iron negative and PAS positive 2substance in the wall. Rabinowitch (1935) speculated that increased serum cholesterol and triglycerides in diabetics enhance arteriosclerosis. However, reports on blood lipids in diabetics and particularly its relationship to the severity of atherosclerosis are still controversial. Man and Peters (1935) reported that they found hyperlipemia in 19 out of 79 diabetics, but there was also 9 cases of hypolipemia. Pomeranze and Kunkle (1950) observed increased serum total lipids in over 50% of 273 diabetic patients, and stated that increased serum total lipids and choleterol with decreased phospholipid: cholesterol ratio cause arteriosclerosis in diabetics. However, Dewind et al. (1952) found that average serum cholesterol level is higher in diabetics than non-diabetics but its range was very wide and no definite correlation was noted between the level of serum cholesterol and severity of atherosclerosis. Not only the disturbance of internal secretion of the pancreas but also the disturbance of external secretion seems to influence on the atherogenesis through its role on lipids absorption (Chaikoff et al. 1952). The present investigation is aimed to investigate the role of diabetes and ligation of pancreatic duct on experimental cholesterol -induced atherosclerosis and to compare these with clinical observations.
