본 연구는 한국의 노동시장에서의 불평등, 특히 직업안정성과 임금획득의 분포에서 나타나는 불평등의 원천에 대한 연구이다. 1986년 노동부에서 실시한'산업체 실태조 사'와 '노동 임금실태조사'에서 추출한 3,169개의 사업체와 거기에 종사하는 18,091명 의 근로자에 관한 정보를 사용하여, 근로자의 개인적인 특성들과 업무의 구조에 관련 된 구조적 특성들이 노동시장 결과물의 분포에서 나타나는 불평등을 어떻게 설명하는 지 분석하였다. 분석의 결과들은 우리나라의 경우 진정한 의미의 '구조'적 특성 즉 업 무구조의 속성중 개인의 속성으로 환원되지 않는 특성은 그 중요도가 선진외국에서 행 해진 사례연구들에 비해 매우 낮은 것으로 나타남을보여주고 있다. 이는 우리나라의 고용제도의 몇가지 특성들과 연결시켜 해석할 수있을 것이다.

유통산업 종업원의 직무불안정성인식이 결과행위에 미치는 영향에 관한 연구
이영환 동아대학교 경영대학원 2009 국내석사
본 연구는 최근 미국발 경제위기와 비정규직이 증가함에 따라 고용환경의 새로운 이슈가 되고 있는 종업원의 직무불안정성에 대한 연구로서 우리나라 유통산업에 종사하는 종업원의 직무불안정성이 그들의 결과행위에 영향력을 미치는지를 조사하고자 하였다. 본 연구목적을 달성하기 위해 직무불안정성에 관한 국내외의 문헌과 자료를 수집, 분석하여 연구모형과 연구가설을 설정하여 설문조사를 통해 실증적으로 검증하였다. 연구조사 범위는 부산, 경남지역에 소재하고 있는 유통산업 제조업체와, 백화점, 대형할인점, 편의점, 슈퍼마켓, 재래시장에 종사하는 종업원을 대상으로 설문조사를 하여 가설검증을 위한 분석을 실시하였다. 자료의 분석방법은 SPSSWIN 14.0 통계패키지를 이용하였다. 그리고 인구통계적 변수들에 대한 표본의 특성을 알아보기 위하여 빈도분석과 기술통계분석을 실시하였으며, Cronbach'α(알파) 계수를 이용한 분석을 하여 자료의 신뢰성과 타당성을 검증하였다. 본 연구의 가설검증은 차이분석과 회귀분석을 통해 가설을 검증하였다. 본 연구의 가설에 대한 검증결과를 요약하면 다음과 같다. 첫째, 개인적 특성에 따라 직무불안정성 인식에 차이가 있는가를 분석한 결과 시간급+성과급의 혼합형의 보수형태 집단이 직무불안정성이 높은 것으로 나타났다. 둘째, 기업환경 변화요인이 직무불안정성의 구성요인인 심리적 불안감과 직무상실에 정(+)의 영향을 미치는 것으로 나타났다. 셋째, 직무불안정성 인식이 결과행위에 미치는 영향력을 검증한 결과 직무불안정성이 높을 수록 직무만족과 조직 몰입이 낮은 것으로 나타났다. 넷째, 직무불안정성 인식은 이직의지나 친조직에 영향을 미치는지를 검증하였으나 영향력이 무의미하게 나타났다.

지역성 실현을 위한 지역전문채널의 활성화 방안 : MBC-NET을 중심으로
This study shows that the government needs to change the policy of local broadcasters to realize regional characteristics and reinforce the competitiveness. Local broadcasters are now in a crisis of identity and management by changes of broadcasting conditions. Local broadcasters urgently need policies that they can approve of general programming channel on their own. That will make them prepare the national window. There is a controversy about the policy's introduction of general programming channel now, but it means that local broadcasters that represent regional characteristics, public interest, publicness for building national balanced values and development must be able to participate in as business. To achieve this, the study has set up five subjects for inquiry. First, what does the government support system need for local broadcasters? Second, why should they carry forward general programming channel as strategies of vitalizing local broadcasters? Third, how are specific plans and business potential for building general programming channel of local broadcasters? Fourth, how effective is general programming channel of local broadcasters? Fifth, how can they draw up a bill for local broadcasters' general programming channel that must be approved by the government? Ruling party officials and B&C(broadcasting and communication) committee are focusing their efforts on carrying forward the introduction of general programming channel for vitalizing the broadcasting industry. These policies, however, are more likely to disturb the media market. It means that local broadcasters are most likely to suffer because they are the weak. In other words, that is why the government should reduce each biased favor to foster the status of general programming channel that receive the same treatment as terrestrial broadcasting. Due to the ruling party's indiscreet broadcasting policies, local broadcasters have much difficulty in performing a role and managing broadcasting companies. This is reality. In this sense, local broadcasters have predicted a crisis and searched for specific alternatives several years ago. One of the alternatives is the first ever super-station channel, MBC-NET that is for competitiveness strength of local broadcasters and balanced national development. MBC-NET began broadcasting in 2007 to realize public values; Nineteen local broadcasters, MBC were united as MBC NET. MBC-NET that has been established with the purpose of general programming channel in the first place has received the containment from the central broadcasting station. Also, politicians and B&C(broadcasting and communication) committee had the lack of knowledge of general programming channel. For those reasons, MBC-NET is maintained only as local speciality channel until now. As built-up results show, however, MBC-NET has offered local various information & culture and prepared the communication window for understanding between regions. It contributes to vitalizing of local broadcasters. It shows that MBC-NET can be an alternative model of local broadcasters that are in crisis of management and identity if MBC-NET becomes general programming channel. Therefore, this study has examined the possibility of promoting of general programming channel and analysis of local speciality channel, MBC-NET that was built as an alternative for crisis of local broadcasters. To achieve this, I've examined closely the reality of local broadcasters by the change of broadcasting conditions in the second chapter after reviewing broadcasting's public interest, regional characteristics and identity of local broadcasters. I've pointed out problems about policies of general programming channel and analyzed contents that have effects on local broadcasters in the third chapter. In the fourth chapter, I've presented the possibility of general programming channel and analyzed and caught problems of local speciality channel, MBC-NET. Finally, I've organized the meaning of research finding by implication in the fifth chapter. To sum up, this study's conclusion is that relaxing of judging standard and an enforcement ordinance revision are needed so that local broadcasters can go into the introduction policy of general programming channel.

This study was reviewed the physical meaning of the wall drag related dispersed flow and its application to thermal hydraulics codes. In the RELAP5 code, the wall drag was modeled by applying the wetted perimeter approach in horizontal bubbly flow. However, this model is showing a result of non-physical phenomenon in which velocity of bubbly flow were predicted faster than the liquid flow during fully-developed horizontal channel in constant area. Therefore, the model in RELAP5 code for bubbly flow in a horizontal channel is improved to distribute wall drag based on the volume ratio of each phase according to Kim et al. (2014, 2015)[5, 6]. The improved model in RELAP5 code was verified by comparing with the experimental data for the behavior of bubbly and liquid flow in an area-varying horizontal channel. The results of experiment showed that the bubble velocity was close to the liquid velocity in a constant area channel. Before the improvement of model in RELAP5 code, the velocity of bubbly flow was faster than the liquid velocity at the same area, but it has been changed to consistent with the experimental results after the RELAP5 code improvement. Finally, the effects of RELAP5 code improvement were performed through SBLOCA calculation of full-scale nuclear power plant. The behavior change of loop seal clearing phenomenon near the transient break size of SBLOCA has been clearly shown in the analysis by the model change. The change of major result of thermal hydraulic behavior in the reactor and peak cladding temperature were confirmed by the influence of changing wall drag model and the loop seal clearing phenomenon.

The present study focuses on some of the most controversial aspects of civil liability in medical malpractice, that is, problems of informed consent, causality, and burden of proof. Methods of the study the present article employed include a survey of relevant professional literature, both domestic ana foreign, and legal cases. These data were systematically analyzed in order to shed light on the problems of civil liability in medical malpractice. Key contents of the study are as follows. (1) In a discussion of informed consent, the author files an intensive criticism, and he regards the informed consent as an independent legal liability so that the overdue responsibility of the physician in question may be alleviated. (2) Over the question on viewing a cause of liability in medical malpractice as a tort or a breach of contract(imperfect performance) or a combination of both tort and breach of contract, and over the method of dealing with the medical malpractice suit, the author weighes merits and demerits of those theoretical perspectives on the basis of data gathered aforementioned. He concludes that a protection for the patient's interest can be legitimately resulted from employing consolidation of claim. (3) In an analysis of theories on the distribution of burden of proof in medical malpractice, the author criticizes formal logic theory of the classification of legal facts thoroughly regardless of viewing the malpractice causality as a tort or a breath of contract(imperfect performance). Thus, he concludes, the burden of proof for the physician's medical malpractice should be based not on the absolute liability bit on the objective nature inherent in the physician's medical practice. Especially, on the theory of conversion on burden of proof to the physician in question, the protection of patient's interest can not be guaranteed from employing a rigid formal types of result of medical malpractice. It can be achieved by allowing the judges to have discretion to determine on the basis of proper interest consideration. (4) In the theory of Anscheinsbeweis(res ipsa loquitur) the author argues that the logical validity of the theory does not directly help to determine the existence of medical malpractice, existence of causal relations, because principles of actual experiences themselves belong to a special area except easy recognition due to the principles of general daily life experiences. Therefore, the analysis of the theory shows that various factors should be considered and reviewed carefully. Thus, the present study argues that a full consideration of these various factors should be included in the theory construction and it also reviews the validity of the application of the results. (5) The theory of conversion on the burden of proof should not be automatically applied for the determination of the physician's liability for the Beweisvereitelung. Only when the judge can be convinced of physician' s Beweisvereitelung according to the preponderance of evidence of common probability, the physician should be liable for the Beweisvereitelung. In conclusion, a characteristic of the study lies in the traditional values and special obligation of medical practice, so-called "Medicine is a benevolent art", which is a good tradition of Korean society, Furthermore, theories on the physician's civil liability in medical malpractice should not be treated with as a general breach of contract(imperfect performance) or a tort. Instead, the study argues a full consideration of special quality of medical obligation so that a theory construction agreeable with the medical reality call be obtained.
