Purpose: This study was done to investigate the effects of university hospital nurses' organizational conflict between organizational commitment and labor union commitment, so as to provide data on prevention of conflict with the hospital and to improve work achievement with commitment of two different groups: hospital and labor union commitment. Methods: Data collection was conducted from May 15 to 31, 2011 for nurses registered in the labor union of a university hospital. The collected data were analyzed using t-test, ANOVA, Scheffe test and multiple regression. Results: Organizational commitment of the nurses showed significant differences according to age, position and work experience, and degree of labor union commitment according to academic achievement. The factors affecting labor union commitment were organizational conflict and recognition of need for labor union, which accounted for 19% of the variance. Factors affecting organizational commitment were organizational conflict, recognition of need for labor union, participation in organizational events, and renewal of membership in the union, which accounted for 33% of the variance. Conclusion: The results of this study indicate that there is a need to improve work achievement by minimizing conflict and preventing labor disputes for better organizational commitment and labor union commitment of nurses.

직무만족이 노조참여를 촉진하는가 아니면 줄일 것인가에 대해서는 오랜 논쟁이 있었다. 본 연구는 직무만족과 노조참여와의 관계에서 노조수단성의 조절효과를 분석하였다. 22개 사업장 826명의 종업원을 대상으로 실증적 조사를 실시하였다. 실증연구의 결과 직무만족과 노조참여 사이에 정(+)의 효과와 부(-)의 효과가 동시에 발견되었다. 직무만족의 노조참여에 대한 직접적인 영향은 정(+)의 효과가 나타났으나, 직무만족과 노조수단성의 상호작용을 함께 고려하였을 때는 직무만족은 노조참여에 부(-)의 효과가 발견되었다. 이러한 결과는 직무만족이 노조참여에 대한 직접적인 관계는 노조참여에 대한 불만관점을 지지해주고 있으며, 직무만족과 노조수단성의 상호작용 효과는 효용관점을 지지해준다. 본 연구는 구성원의 직무만족이 독자적으로 노조참여에 영향을 미치는 경우 보다는 직무만족과 노조수단성과 유기적인 상호 연계가 이루어질 때 노조참여 효과가 더욱 강화될 수 있음을 시사하고 있다. 따라서 실무적 측면에서 노조가 노조활성화를 기대한다면 근로자의 근로조건과 거리가 먼 정치투쟁적 노동운동보다 노조원의 기대를 충족해 줄 수 있는 다양한 서비스에 초점을 맞춘 노동운동이 중요하다는 것을 시사한다. 이를 통해 우리나라 노동조합이 나아갈 방향을 제시해준다.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of hospital organization management. The subjects of this study were 510 employees in 1 University Hospital and 3 General Hospitals in Metro Capital including Seoul. Materials were collected from administrators, nurses and medical technicians in target hospitals from April 26 to May 7, 2004 through survey questionnaires. The main results of this study were as follows: First, From the results of multiple regression analysis to identify major influencing factors of labor union commitment level, In University hospitals, males than females, and those who had senior officer posts in labor union showed higher positive correlation with the attitude of their colleagues. In general hospitals, those who had served in Union for shorter period showed higher commitment in union. Second, When looking into the major influencing factors on the level of commitment in labor union according to their jobs, male administrators showed higher positive correlation in the level of commitment in labor union and the relationship with union. Among nurses, those who had lower education level, those who had higher job satisfaction, those who had higher emotional attachment to their job, those who had better relationship with union and better satisfaction in union showed higher commitment level. In medical technicians, those who had higher emotional attachment to their job showed higher commitment level. To summarize study results, the level of commitment in labor union depends on job satisfaction, managers' attitudes, emotional attachment to their jobs, union satisfaction factors, their colleagues attitudes toward union and thee atmosphere of employer-employee relationship. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as job satisfaction is important determinant in union commitment, hospital managers should have countermeasures to enhance the job satisfaction level of hospital employees. Moreover, as managerial factors of the principal of hospital influence union commitment directly, the attitudes of hospital managers toward union and transparency of hospital management should be improved.

이 논문은 노동조합이 기업의 이윤율에 미치는 효과를 실증분석하였다. 한국상장회사협의회의 "TS2000"에서 1990-2009년 기간 동안 20년 자료를 패널데이터로 구축하여 그 중 표본기간 동안 노조조직 상태가 변하지 않은 기업들(불변그룹)과 표본기간 동안 노조가 없다가 생긴 기업들(변화그룹)로 표본을 나누어 분석하였다. 분석 결과, 불변그룹 표본에서 노조기업 여부는 자본 수익률(ROE)에 유의한 차이를 주지 않는 것으로 나타났다. 그러나 변화그룹 표본에서는 노조 더미가 자본수익률을 낮추는 것으로 나타났다. 따라서 동일한 기업에서 노동조합이 조직되면 이윤율은 낮아지는 것으로 판단된다.

The purpose of this study was to provide basic materials needed to enhance quality of organizational life by identifying the improvements of labor union management in the perspective of hospital organization management. Materials were collected from administrators, nurses and medical technicians in target hospitals from March 3 to March 3 to March 30, 2010 through survey questionnaires. The main results of this study were as follows: 1. The commitment level of the subjects according to their satisfaction was higher when the administrators both in Private hospitals and Public hospitals were not satisfied in their works. 2. The commitment level of the subjects according to the subjects' job dedication level was higher those who had higher emotional attachment to their job in all vocations in both Private hospitals and Public hospitals. 3. The commitment level of the subjects according to the subjects' labor union involvement was higher in those who had higher satisfaction in labor union and perceived their colleagues' attitudes more positively in all vocations in both Private Hospitals and Public Hospitals. 4. From the results of multiple regression analysis to identify major influencing factors of labor union commitment level, In Private hospital employees, those who had senior officer posts in labor union and higher normative commitment showed higher commitment union. Therefore hospital managers should have democratic and flexible attitudes toward labor union. Additionally, as colleagues attitudes is important determinant in union commitment, hospital managers should have countermeasures to enhance the work atmosphere of hospital employees.

기업이 살아남기 위해서는 이윤을 추구해야 하는 것 뿐 만 아니라 사회적 책임이 요구된다. 이러한 사회적 책임은 비단 기업 뿐 만이 아니라 기업의 하위시스템인 노동조합에도 사회적 책임이 요구된다. 그러나 이러한 노조의 사회적 책임(Union Social Responsibility, 이하 USR)에 대한 실행사례와 이에 대한 연구는 미미한 것이 사실이다. 노동조합이 지속적으로 생존하고 그 역할을 다하기 위해서는 조합원들만의 기대를 충족시키는 것은 기본이고, 비노조원, 지역사회 등 노동조합과 관련된 이해관계자들의 기대를 충족시켜야 한다. 이에 본 연구에서는 노조의 사회적 책임에 대해 우리나라에서는 선도적이라 할 수 있는 LG전자 노동조합의 USR사례를 살펴보았다. LG전자 노동조합은 2010년 USR을 도입하면서 노동운동의 변화를 추진하였고, 지역사회와 취약계층에 대한 봉사와 파업 자제를 통한 산업평화 확립, 환경보호 등과 같은 내용의 USR을 실천하였으며, 국내 사업장 뿐 만 아니라, LG그룹 내부 및 해외사업장에도 이를 전파하였다. 본 연구에서는 이러한 LG전자 노동조합의 사례를 통해 사회적 존재로서의 노동조합의 새로운 길에 대해 모색하고자 한다.

이 글은 미국 최대 독립 정유회사인 Valero Energy에 대한 사례연구로서, 비노조 기업의 기업문화와 인적자원관리의 특징을 살펴보기 위한 목적 하에 작성되었다. 1980년 설립 이래 Valero는 유전지역인 텍사스 기반 지역기업으로서 남부지역 정서에 부합하는 비노조기업 성격이 뚜렷하다. 강력한 CEO 리더십, 종업원 최우선 정책과 팀워크 강조 문화, 확고한 고용보장정책(no lay-off policy) 및 인사업무 외주화 금지 정책, 업계 중상위권의 임금수준과 업계 최고 수준의 복리후생, 비노조전통과 이를 보완하는 공정한 고충해결 시스템 구비 노력 등 미국 비노조기업의 인적자원관리 특징들을 잘 보여주는 전형적인 예에 해당한다. 2010년 이전까지 엄청난 성장과 수익성 제고에 기반하여, 한계기업이 선호하는 노조압박방식 대신, 우량기업이 채택하는 노조대체방식을 노조회피전략의 구체적인 방안으로 실행하여 왔다. 하지만, 최근 들어, 지속적인 인수합병으로 인한 기업 인력 내 이질성 확대, 유가 하락 등으로 인한 고용보장정책 유지의 어려움과 정리해고 실시 필요성 증대 등으로 인해 Valero의 노조대체방식에 기반한 노조회피전략은 본격적인 시험대에 올라가고 있다.

Objective: To evaluate the image quality of novel dark-blood computed tomography angiography (CTA) imaging combined with deep learning reconstruction (DLR) compared to delayed-phase CTA images with hybrid iterative reconstruction (HIR), to visualize the cervical artery wall in patients with Takayasu arteritis (TAK). Materials and Methods: This prospective study continuously recruited 53 patients with TAK (mean age: 33.8 ± 10.2 years; 49 females) between January and July 2022 who underwent head-neck CTA scans. The arterial- and delayed-phase images were reconstructed using HIR and DLR. Subtracted images of the arterial-phase from the delayed-phase were then added to the original delayed-phase using a denoising filter to generate the final-dark-blood images. Qualitative image quality scores and quantitative parameters were obtained and compared among the three groups of images: Delayed-HIR, Dark-blood-HIR, and Dark-blood-DLR. Results: Compared to Delayed-HIR, Dark-blood-HIR images demonstrated higher qualitative scores in terms of vascular wall visualization and diagnostic confidence index (all P < 0.001). These qualitative scores further improved after applying DLR (Dark-blood-DLR compared to Dark-blood-HIR, all P < 0.001). Dark-blood DLR also showed higher scores for overall image noise than Dark-blood-HIR (P < 0.001). In the quantitative analysis, the contrast-to-noise ratio (CNR) values between the vessel wall and lumen for the bilateral common carotid arteries and brachiocephalic trunk were significantly higher on Dark-blood-HIR images than on Delayed-HIR images (all P < 0.05). The CNR values were significantly higher for Dark-blood-DLR than for Dark-blood-HIR in all cervical arteries (all P < 0.001). Conclusion: Compared with Delayed-HIR CTA, the dark-blood method combined with DLR improved CTA image quality and enhanced visualization of the cervical artery wall in patients with TAK.
