일-가정 갈등이 이직의도에 미치는 영향 - 유연근무제 만족도를 중심으로 -

이 선 경,이 춘 우,김 상 순 한국인적자원관리학회 2014 인적자원관리연구 Vol.21 No.5

일-가정으로부터의 상충되는 요구로 인해 조직구성원은 갈등을 겪게 되고 이러한 갈등은 조직목표 달 성을 어렵게 하는 요인이 된다. 기존 연구는 일-가정 갈등(Work-Family Conflict: WFC) 양상에 주목하 는 반면 갈등초래의 원인에 대해서는 제한적인 관심을 보여 왔다. 이에 본 연구에서는 자원소모 모형 (Resource drain model)을 기반으로 갈등의 원인에 따라 일-가정 갈등(WFC)을 일-가정 방해 갈등(Work Interference with Family: WIF), 가정-일 방해 갈등(Family Interference with Work: FIW)으로 나누고 갈등의 원인을 시간, 긴장, 행동의 영역으로 세분화하여 구성원의 이직의도에 영향을 주는지 살펴보았다. 아울러 직무특성화 모델(Job characteristics model)을 활용하여 유연근무제에 대해 조직구성원이 느끼는 만족도가 높을수록 시간 통제감과 자율성을 가지게 되어 일-가정 방해 갈등(WIF)이 이직의도에 미치는 영향을 낮출 것이라 예측하였다. 대기업 직장인 143명으로부터 얻은 설문 테이타를 이용하여 상관분석과 위계적 회귀분석을 하였다. 분석결과 일-가정 방해 갈등(WIF)은 이직의도에 영향을 줌을 알 수 있었고, 일-가정 방해 갈등(WIF)의 부정적인 영향을 감소시키는데 유연근무제의 만족도가 높을수록 효과적인 사실도 확인하였다. 본 연구의 이론과 실증결과는 일-가정 갈등(WFC)이 원인에 따라 이직의도에 주는 영향이 다름을 밝혔고, 기업과 경영자들에게 유연근무제가 일-가정 방해 갈등(WIF)을 효과적으로 관리할 수 있는 전략적 제도가 될 수 있음을 보였다는데 의의가 있다. Contradicting demands from work and family challenges organizational members, making them less committed to organizational goals. Existing studies tend to focus more on work-family conflict as organizational phenomenon but less on the causes of such conflict. Building upon the resource drain model and using the origin of conflict as a criterion, this study categorizes work-family conflict into work interference with family (WIF) and family interference with work (FIW), introduces time, strain, and behavior as three dimensions of conflict, and examines their influences on employee turn-over intention. Additionally, this study, drawing from job characteristics model, predicts that organizational members’ satisfaction with flexible work practice will reduce the effect of WIF on turn-over intention as the members feel more empowered with perception of time-control and autonomy. Using the survey data from employees of major corporations in Korea, this study run correlation and hierarchical regression analyses. Results show that WIF has a significant influence on employee turn-over intention and that employee satisfaction on flexible work practice effectively decreases the harmful impact of WIF on turn-over intention. The results of this study contributes to the research by showing that work-family conflict has a deferential effect on turn-over intention depending on where the origin of conflict resides. This study also offers a practical implication to managers by proposing that flexible work practice, unlike conventional view as a welfare policy, can be a strategically meaningful practice that can not only effectively reduces employee turnover but also fundamentally solve the problem of work-family conflict.

. The purpose of this study was to confirm the efficacy of Magnolia kobus ethanol extract (MKEE) on various biological targets of a cosmetic ingredient. Suppressed production of NO and PGE2, inflammatory mediators induced by LPS, also inhibited the activity of 11β-HSD1, an enzyme that converts cortisol, a stress hormone that causes inflammation. Excessive production of sebum caused by palmitic acid was significantly inhibited by MKEE, and inhibition of the lipase activity of Malassezia furfur, a lipophilic bacterium that metabolizes sebum, was also confirmed. In addition, MKEE can inhibit the growth of four type of skin bacteria that produce volatile organic substances that cause body odor, and the minimum inhibitory concentration (MIC) for each bacteria was in the range of 2 to 8 mg/mL. These results, which indicate the various physiological activities of MKEE, suggest its potential for use as a cosmetic material that can be applied to various parts of the body.

외상성 가사 : 3 Case Report 3례 보고

Traumatic asphyxia is a clinical symptom complex characterized by craniofacial cyanosis, subconjunctival hemorrhage, and head and neck vascular engorgement due to sudden compressive injury on the thoracic cage. It is occasionally combined with mental deterioration, lung contusion, and edema. It is considered due to increased intrathoracic pressure in state of closed epiglottis. Recently, we had experienced three cases of traumatic asphyxia of which clinical courses were somewhat different. The first case developed by a compression between a elevator and the ground while the victim did not realized the accident happening, and the patient showed nonspecific facial edema and ecchymosis but mental deterioration and ultimate respiratory failure. The second case by a compression between cars, while the impending accident was noticed by the victim, showed full-blown asphyxia without mental or respiratory symptoms. The last case by forceful coughing and vomiting showed facial edema and ecchymosis without any other symptoms. Hospital course of all cases were uneventful. We believe that "fear response" or "closure of the epiglottis" might be an important mechanism on developing symptom of traumatic asphyxia.

A Comparative Analysis on Cross-border Insolvency Legislation of Japan, Korea, China and UNCITRAL Model Law

오수근,陈 景 善 한국법제연구원 2023 KLRI journal of law and legislation Vol.13 No.2

Divided jurisdictions under the national law system have yet to address legal issues in cross-border cases, including insolvency. UNCITRAL Model Law on Cross-border Insolvency is a solution for divided jurisdictions. More than 60 countries, including leading states in a global economy, have adopted the Model Law, of which key provisions are access, recognition, relief, and cooperation and coordination. The actual provisions of local legislation, however, are different from the Model Law, not to mention each other. In this article, the co-authors identify the differences in cross-border insolvency rules of Japan, Korea, China and the Model law. Analyzing the reason for those disparities, they find that adopting the Model Law is a type of legal transplantation, and those disparities are feedback to the Model Law. If the Model Law acknowledges and reflects them in its further amendments, another global rulemaking process will start. Co-authors conclude that the disparities are natural outcomes and do not mean the failure of the Model Law. In addition, they suggest that Japan, Korea, and China build leadership in a global rulemaking.

체내 이식형 의료장치들은 개발과정에서 임상적용전 사체실험(preclinical cadaver fitting test)을 실시하게 된다. 이를 통해 기계장치의 크기와 모양 및 구조 등이 인체 해부구조에 적합한지를 평가하고, 체내 이식에 적합한 최적의 위치를 결정하며, 임상에 적용가능한 수술술기를 완성할 수 있다. 저자들은 고려대학교 해부연구위원회의 승인을 받은 총 12구의 사체를 이용하여 자체 개발한 한국형 인공심장(AnyHeart)의 인체적용의 해부학적 적합성을 평가하였다. 관찰목표는 서로 다른 가슴안 접근법(복장뼈정중절개술, 오른쪽 개흉술, 왼쪽 개흉술, 복장뼈횡절개술)에서 인공심장의 적절한 이식 위치, 유입로와 유출로의 확보 및 도관의 삽입 위치 등이었다. 연구 결과 한국형 인공심장의 인체적용의 해부학적 적합성은 뛰어났으며, 특히 새로운 수술기법인 오른쪽 개흉술을 통한 인공심장 이식술을 가능하게 하였다. 본 연구를 통해 향후 본격적인 임상 시도의 토대를 마련하였고, 체내 이식형 의료장치의 개발과정에서 해부학적 적합성 평가의 중요성을 확인하였다. Preclinical cadaver fitting study is paramount in the development of various implantable medical devices. It helps to evaluate the fitness of the size, shape, structure of the devices in the human anatomy, to locate the most optimal site for implantation, and to develope the clinically available surgical techniques. The purpose of this study was to observe the anatomical feasibility of Korean artificial heart (AnyHeart) in 12 human cadavers after obtaining the permission from the Korea University Anatomical Research Committee. The observation was focused on proper position of the artificial heart in various thoracic incisions (median sternotomy, right thoracotomy, left thoracotomy, transsternal incision), localization of inflow as well and outflow tract, cannulation sites, and so on. Results showed that Korean artificial heart had excellent anatomical feasibility in the human body and that a novel surgical technique of right thoracotomy approach was proved to be clinically applicable. Conclusively, the above results will provide the rationales of clinical trial and demonstrate the significance of human cadaver study in development of implantable medical devices.
