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.

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.

In order to minimize radiation exposure and secure diagnostic value images during CT examination of the head of children, the usefulness of volume axial mode is evaluated through comparison and analysis of exposure dose and images of volume axial mode, high pitch mode, and helical mode. Image evaluation and dose evaluation were performed in CT high pitch mode, helical mode, and volume axial mode for infants under the age of 1 according to the voltages of 70, 80, and 100 kVp tubes. The image evaluation was conducted by comparing image quality by setting ROI for each image, calculating SNR and CNR, using ONE-WAY (ANOVA) to evaluated statistical significance, and cross-examining the dose evaluation using DLP values displayed in the Dose Report. When inspected using volume axial mode, DLP values were generally low, and SNR and CNR values differed by ROI and kVp. When volume axial mode evaluated the quality of the image compared to other scan modes, the difference is not uniform. For the reason, certain modes are not considered excellent, but the exposure dose was reduced the most in terms of dose. In addition, the point that the volume axial mode can be examined at its original location, short scanning time and needless of table movement is useful for CT tests for children under 1 year of age with high radiation sensitivity.
