노동계급은 다양한 형태의 내적 이질성을 지니고 있으며, 신자유주의 경제정책과 구조조정 과정에서 고용형태에 따른 이질성은 계급균열로 발달하며 노동계급 내적 이질성 논의의 핵심을 구성하게 되었다. 국내의 선행 연구들도 정규직과 비정규직 사이의 물질적 존재조건의 양극화 추세와 사회적 관계의 위계적 배제적 성격을 확인해 주고 있다. 하지만 정규직과 비정규직 사이의 계급균열이 극복되고 노동계급의 내적 통합과 계급형성 과정을 이룰 수 있는지에 대한 논의로 발전하지는 못했다. 본 연구는 계급균열의 극복과 노동계급 통합의 가능성을 검토하기 위해 계급균열의 핵심인 비정규직 노동자 문제를 둘러싼 정규직 비정규직의 의식 수준의 비교연구를 실시한다. 본 연구는 민주노총 공공운수연맹 노동조합원들에 대한 설문조사와 심층면접 연구를 통해 계급균열의 존재를 확인하고 그 원인과 의미를 분석하였다. 첫째, 정규직과 비정규직 노동자들은 비정규직 문제에 대한 인식을 공유하고 있지만 구체적 해결책에 대해서는 입장 차이를 보임으로써 고용형태에 따른 계급균열은 존재하며, 경제위기 이후에도 해소되지 않고 고착화되고 있음을 확인시켜 주었다. 둘째, 고용형태에 따른 계급내적 균열이 비정규직 문제 인식과 추상적 원칙 수준에서는 유의미한 의식 차이를 보이지 않지만 비정규직 문제 해결을 위한 구체적 해결책에 대해 유의미한 입장 차이를 보이는 것은 정규직과 비정규직 사이의 물질적 이해관계의 차이 때문이다. 정규직 노동자들은 비정규직 노동자들의 고용안정성과 노동조건의 개선을 허용하더라도 자신들의 이해관계가 위협받지 않는 수준에서 이루어져야 한다고 보는 것이다. 셋째, 정규직 노동자들이 추상적 원칙 수준에서는 비정규직 노동자들과 동질성을 보이지만 구체적 대안에서 차별성을 보이는 것은 정규직 노동자들의 의식의 양면성을 표현하는 것이며, 물질적 이해관계에 기초한 개인적 수준의 합리성과 계급적 원칙에 기초한 계급적 수준의 합리성이 갈등하고 있는 것이다. 넷째, 정규직 노동자들의 주관성 속에서 개인적 합리성과 계급적 합리성이 갈등하는 정도는 노동조합 가입 여부 및 소속 노동조합의 정체성, 즉 이익집단 정체성 혹은 계급조직 정체성에 의해 결정된다. 여기에 계급조직 정체성을 지닌 민주노조들이 노동계급 계급균열을 극복하고 계급형성을 이루는데 기여할 수 있다는 실천적 함의가 있다.

Background: Research in environmental health (EH) is of crucial strategic importance for contemporary society. It is becoming even more critical in light of the increasingly rapid pace of environmental changes, opportunities, and threats. Objectives: This study aimed to identify trends and the prospective of environmental health research using SWOT analysis. Methods: The trends in environmental health research were reviewed in previous studies and reports. Reviewed manuscripts were searched for using the keywords of 'environmental health' and 'environmental hygiene' in the KCI (Korean Journal of Citation Index), KISS (Korean Academic Information), PubMed, and Google Scholar. Results: It is essential to center the EH research agenda around key priorities focusing on technological innovation, job creation, and the increasingly prominent role of the private sector. Given the rapidly evolving global sustainability agenda, greater clarity on the ever-increasing sources of complexity and growing expectations of the public might be needed. This requires the identification of criteria to identify EH research priorities with the ultimate goal of maximizing societal benefit. Public health relevance, such as extent and severity of health impact, level of exposure, and inequalities of effects, could be included. Conclusions: Considering the recent interest in and importance of environmental health, a comprehensive approach to environmental health research should be required through the application of the latest science and technology, citizen participation, and environmental health surveillance systems.

Plato's Laws, Bk. 10 is made up of cryptically concise expressions and complex arguments, so that it is not simple to understand it. In this essay I would like to make use of Stoic perspective as an interpretative instrument, which would enable me, I hope, to reconstruct the main arguments of the Laws, Bk. 10 into an intelligible form. Through this approach we would have an opportunity to meet with some important philosophical ideas of Plato which did not reveal themselves clearly in other, especially early and middle dialogues. These ideas comprise the inseparability of the soul from the body, the intellectualization of nature, the human being as a part of the cosmos and the extensional overlapping of the moral law and the natural law. And at the same time my study would result in making a suggestion for history of reception. That is, in this paper I will find some grounds in the tenth book of the Laws that would show how great the influence of Plato upon the Stoics was. For we have but little knowledge about the possibility of the power of Plato's influence upon the Stoics, even though the scholarship on the Stoics until now shed some light on the features and range of Aristotle's influence upon them.

In modern times, damage caused by the spread of the Internet has become very diverse. In particular, due to the craze of K-pop since 2008, the damage caused by copyright infringement in the domestic and international music markets has become the biggest problem in the Internet market. However, the manpower of the police and copyright protection agencies to solve these increasingly intelligent crimes is insufficient. Therefore, we are trying to find out the role of the public interest detective as a supplementary force for the public authority and as a substitute for the copyright protection agency that can provide legitimate help for victims in the prevention of music copyright infringement and disputes. For this study, first, the concept and types of music copyright, the concept of public interest detectives, the current status and system of music copyright were identified, and the role of detectives for music copyright protection was explored through system operation and status analysis of protection agencies and literature review. Through the results of this study, it is hoped that the role of a professional detective in the public interest dimension of music copyright protection can be a good soil for the development of the detective industry in the future.

Purpose: This in vitro study aimed to evaluate the clinical acceptability of precision of fit of the support thickness of Co-Cr alloy copings fabricated using selective laser melting (SLM). Methods: Thirty dental stone models of maxillary left molar abutments were manufactured, images were taken using a scanner, and a computer-aided design program was used to design the form of a conventional metal ceramic crown coping. Overall, 30 single copings were made from Co-Cr alloy using SLM and divided into three support radius groups (0.1, 0.25, and 0.35 mm) of 10 for each. Digitized data were superimposed with three-dimensional inspection software to quantitatively obtain the machinability of a ceramic crown coping, and visual differences were confirmed using a color map. The root mean square values of the ceramic crown coping group were statistically analyzed using one-way analysis of variance (α=0.05). Results: The precision of fit was superior with 0.25 mm compared with 0.1 mm and 0.35 mm, and the results exhibited significant differences (p<0.05). All specimens showed that various support thicknesses did not exceed the clinically permitted value of 120 ㎛, which mean that more than 0.1 mm and 0.35 mm of support radius for SLM was adequate. Conclusion: The support thickness of Co-Cr alloy restoration fabricated using SLM is shown to affect the adaptation.

This study focuses on the potential for creating spatial and atmospheric effects in small theaters using mobile stage equipment, without being constrained by physical space or theater facilities, for mega musical productions. With the continuous growth of mega musicals in the domestic market, the study analyzes the distribution and sales of musical works in Korea and proposes methods for creating spatial effects in university musical education to facilitate the production of mega musicals in small theaters. The mobile stage equipment is designed based on the principle of the periaktoi, a stage mechanism used in ancient Greek theater and the characteristics of mobile stage equipment used in musicals such as <Notre Dame de Paris> and <Laundry>. The mobile stage equipment is a four-sided column-shaped device, which is applied to the musical <Les Misérables> to derive the potential for creating spatial effects, representing the inner state of characters, and forming the mood of the drama. The study is expected to provide opportunities for performing mega musical productions in university musical education and to contribute to the development of the musical industry and education. The utilization of mobile stage equipment demonstrates the possibility of producing mega musical productions in small theaters.

Diffuse interstitial lung disease due to a wide variety of conditions are amenable to diagnosis by means of clinical evaluation, bronchoalveolar lavage, transbronchial biopsy and lung biopsy. The recently introduced technique of thoracoscopic wedge biopsy provides the potential advantages of greater selection of biopsy site and reduced postoperative chest pain compared with the standard open lung biopsy Video assisted thoracoscopic lung biopsy was performed in twenty patients for diagnosis of diffuse in- terstitial lung disease during the period from January 1993 to June 1994. The ages of the patients ranged from 18 to 69 years(mean 48.5 years), and the patients consisted of 10 males and 10 females. In all twenty, thoracoscpic lung biopsy samples were obtained; 9 from left lower lobe, 7 from right lower lobe, 2 from right upper lobe, 1 from left upper lobe, and 1 from right middle lobe. All patients were correctly diagnosed. The two common diseases were usual in erstitial pneumonia(UIP)(8120) and mil- liary tuberculo si s(4120) . Mean duration of the chest drainage was 3.2 days. There was no complication.

The purpose of the study was to analyze American teacher quality management system and provide it's implications. For this, the study analyzed the main traits of American teacher policy, Pennsylvania State University's teacher cultivation system, Pennsylvania State's teacher certification, selection, and recruit system, the master teacher system of New Jersey and New York State. The main results are as the followings. First, American teacher policy is variously operated by state government and school district based on variety and autonomy. Second, for teacher cultivation in American teacher policy, the evaluation on the teacher cultivation program of teacher cultivation institute(mainly university) is strictly administrated. Third, for teacher certification, various tests for gaining teacher certificate are administered and standardized tests are used for the tests. Fourth, for teacher selection and recruit, there is no special test for selection and teacher recruit is done by contract. Fifth, for quality management using excellent teacher, America is administering master teacher that is similar with master teacher system in Korea. Finally, the innovation of teacher cultivation institute by introducing Every Student Succeeds Act(ESSA) is anticipated. Based on these results, the implications for Korean teacher policy were provided.

This study was conducted to compare and analyze the curriculum of early childhood education in South Korea and North Korea in order to establish the direction of early childhood curriculum. Based on this, the purpose of the study is to propose educational alternatives for possible integration. The comparison of North and South Korean early childhood education curriculum was conducted in terms of educational goals, early childhood curriculum area and daily management, teaching and learning methods, and assesment. As a result of the study, there were more differences found than similarities in various areas due to differences in the educational philosophy between South and North Korea, and the following implications were drawn. First, in order to integrate North and South Korea's early childhood curriculum, a new educational ideology that reflects the unique function and purpose of education should be established first, and specific curriculum and contents should be developed accordingly. Second, the most significant difference in the content and operation of North and South Korean early childhood education curriculum is political ideology education, which is the most important content of the North Korean early childhood education course. Third, in order to integrate the South and North Korea early childhood education curriculum in preparation for unification, it is necessary to organize and standardize the terms related to early childhood education in order to unify them. In order to do this, it is necessary to try to integrate them gradually starting from areas showing similarities, and to endeavor to overcome discrepancies through mutual exchange between South and North Korea.

This study aims at comparing and analyzing early childhood education systems in both South and North Koreas and suggesting educational alternatives for integrating in various aspects based on it, in order to build directions of early childhood education system in the preparation of Unification. A comparative study on the early childhood education system in South and North Korea was done in terms of early childhood education, public education of early childhood. As a result, there were differences rather than similarities in many areas due to the differences of political ideology between the South and the North. First, early childhood is not compulsory, but becomes public in South, while it is partially compulsory and has an overall public system in North in terms of its compulsory education and Pulic education. Second, as a result of comparing operating systems depending on early childhood education institutions in the South and North, there were differences in various areas such as subjects of foundation, classification of age, operating types, etc. Third, looking at its administrative support system, two Koreas has a similarity of a overall dual system, but showed a specific difference. Fourth, its public support had a similarity that early childhood education is done free of charge in two Koreas. In light of the results of comparing the early childhood education system in South and North Korea, this study suggests the following implications. First, as part of an effort to restore similarities of the early childhood education system between two Koreas, a challenge that must be addressed with priority is to integrate early childhood education-nursery in the early childhood education for age 3-5. Second, we'll take an effort to include the early childhood education for age 3-5 in the basic disciplines with 'Making early childhood education public' being currently focused. In addition, we should an attitude to recover a similarity through mutual exchange and to have advantages of the early childhood education in two Koreas as a challenge of taking an effort to integrate the early childhood education in the South and the North various studies and debates, discussions will be made for the meaning of the early childhood education and the integration.
