  • Galaxy clusters, the largest gravitationally bound systems, are an important subject of study to place constraints on cosmological models. Moreover, they are excellent places to test galaxy evolution models in connection to their environments. To date, massive clusters have been found unexpectedly (Kang & Im 2009; Gonzales et al. 2012) and the evolution of galaxies in clusters is still controversial (Elbaz et al. 2007; Faloon et al. 2013). Finding galaxy cluster candidates at z > 1 in a wide, deep imaging survey data will enable us to solve such issues of modern extragalactic astronomy. We report new candidate galaxy clusters in one of the wide and deep survey fields, the European Large Area ISO Survey North1 (ELAIS-N1) and North2 (ELAIS-N2) fields, covering a sky area of $8.75deg^2$ and $4.85deg^2$ each. We also suggest a new useful color selection technique to separate z > 1 galaxies from low - z galaxies by combining multi-wavelength data.

  • The beauty of the laryngeal mask is that it forms an air tight seal enclosing the larynx rather than plugging the pharynx, and avoid airway obstruction in the oropharynx. The goal of its development was to create an intermediate form of airway management face mask and endotracheal tube. Indication for its use includes any procedure that would normally involve the use of a face mask. The laryngeal mask airway was designed as a new concept in airway management and has been gaining a firm position in anesthetic practice. Despite wide spread use the definitive role of the laryngeal mask airway is yet to be established. In some situations, such as after failed tracheal intubation or in oral surgery its use is controversial. There are several unresolved issues, for example the effect of the laryngeal mask on regurgitation and whether or not cricoids pressure prevents placement of mask. We review the techniques of insertion, details of misplacement, and complications associated with use of the laryngeal mask. We then attempt to clarify the role of laryngeal mask in air way management during anesthesia, discussing the advantages and disadvantages as well as indications and contraindications of its use in oral and maxillofacial surgery.

  • WRC-03 was held between 9 June and 4 July 2003 in Geneva, Switzerland. Over 2,200 delegates from 138 ITU Member States attended the Conference. The delegates considered some 2,500 proposals, and over 900 numbered documents related to 50 agenda items. The final output of the Conference consists of 527 pages of new and revised text of the Radio Regulations. This paper provides some details about the outcome of the radio astronomy related issues at the WRC-03 Conference. It is divided into two part: a) Agenda item1.8.2 and b) Agenda item 1.32, related to radio astronomy. Relevant extracts from the Final Acts of WRC-03 are given in the Appendix. Agenda item 1.8.2 was one of the most controversial Agenda Items at WRC-03. Studies were carried out within ITU-R TG 1/7 for the last three years; the results of these studies are summarized in Recommendation ITU-R SM.1633. The Conference adopted a new footnote (5.347A), that calls for the application of Resolution 739 (WRC-03) in the 1452-1492 MHz, 1525-1559 MHz, 1613.8-1626.5 MHz, 2655-2670 MHz, 2670-2690 MHz and 21.4-22.0 GHz bands. Agenda item 1.32 is to consider technical and reglatory provisions concerning the band 37.5-43.5 GHz, in accordance with Resolutions 128 (Rev.WRC-2000) and 84 (WRC-2000). WRC-03 reviewed and adjusted the New footnotes 5.551H and 5.551I cover the protection of radio astronomy observations in the 42.5-43.5 GHz band from unwanted emissions by non-geostationary (5.551H) and geostationary (5.551I) FSS and BSS systems, respectively.

  • 국가는 그 구성원들의 삶의 방식에 개입해야 한다는 공동체주의적 완전주의도 틀렸고, 국가는 삶의 방식에 대해 중립적 입장을 유지해야 한다는 자유주의적 반완전주의도 틀렸으며, 공동체적 자유주의가 옳다. 공동체적 자유주의의 입장에 서면, 세상의 모든 국가공동체는 그 나름의 도덕교재를 만들어야 한다. 그리고 교육을 통해 각각의 공동체가 추구하는 공동선의 실현에 적합한 인간을 육성해야 한다. 당연히 대한민국이라는 국가공동체의 도덕교재는 '바람직한 한국인'을 양성하는데 적합한 방식으로 구성되어야 한다. 따라서 통일교육과 시민적 덕성을 주제로 한 교육이 도덕교재 안에 포함되는 것이 허용될 수 있다. 그럼에도 불구하고 사회과는 공동체의 구성원들이 공유하는 가치들을 주입식으로 내면화한다면, 도덕과는 반성적 내면화 시켜야 한다는 점에서 큰 차이가 있으며, 따라서 교육주제의 중첩성이 양 교과의 정체성을 뒤섞는 것은 아니다. 혹자는 도덕교육에서 '반성적 내면화'를 강조하는 것은 도덕교육이 윤리학 교육이 될 것이라고 걱정할지 모르겠다. 그러나 다양한 윤리사상과 가치들 간의 대립을 반성적으로 '검토'하는 것은 윤리학의 할 일이지만, 도덕과는 학생들에게 한국인의 삶의 방식과 가치들을 반성적으로 '내면화'시킨다는 점에서 윤리학 교육과는 다르다. 한국 사회의 공유된 가치들 즉 한국사회의 잠정적인 도덕적 진리들을 반성적으로 내면화한 '바람직한 한국인'은 자국중심주의와 세계시민주의라는 두 세계의 시민이다.

  • SOC 투자를 위한 경제성 평가에서 벌크화물의 시간가치를 반영해야 하는지에 관한 논의가 지속되고 있다. 본 연구는 벌크화물의 시간가치 반영을 위해 검토해야 할 기본 사항들을 제시하는 목적으로 수행하였다. 연구의 내용은 우선 외국의 반영 현황과 관련 연구사례 및 국내 적용 시 한계점 등을 파악하였다. 벌크화물의 시간가치 반영 방법은 국가별로 다르며 반영의 강도 역시 차이가 나타났다. 또한 운송수단 선택모형을 통해 도출한 시간가치를 반영하는 것도 아직 논란이 예상되었다. 본 연구는 이러한 한계들을 감안하여 향후 시간가치 반영을 위한 기초환경 구축 방향을 제시하였다. 벌크화물 시간가치 반영은 필요성이 충분히 인정되지만 실제 적용하기까지는 선제적으로 검토하고 해결해야 할 사항들이 있다고 판단된다. 이를 보완하기 위해 후속연구가 지속될 필요가 있으며, 이를 통해 보다 명확한 가이드라인이 마련되기를 기대한다.

  • Background: Cervical mobilization has been applied mainly for the improvement of arm and neck movements and pain reduction, and little research has been done to improve the executive function. Since this kind of so-called mechanical neck pain is one of most common symptoms, there are controversial issues about this with spine alignment. Posteroanterior (PA) mobilization from the Maitland concept is a process of examination, assessment, and treatment of neuromusculoskeletal disorder by manipulative physical therapy. Objective: To examine the short-term benefits of mobilization for patients with non-specific neck pain. Design: Dual-group Pretest-Posttest Design from the Quasi-Experimental research Methods: Fourteen participants (male 8, female 6; 20's of their age) with non-specific neck pains which are distributed all the unilateral or bilateral body side were recruited. Participants were categorized to Neck Pain with Movement Coordination Impairments (NPMCI) and Neck Pain with Mobility Deficits (NPMD) groups according to the results of physical examination. Professional physical therapist who has over 15-years-of clinical experience applicated manipulative therapy for the neck pain, an occupational therapist only conducted evaluations; K-NDI (Korean version of the Neck Disability Index), VAS (Visual Analog Scale), BDS-K (Korean version of Behavioral Dyscontrol Scale) for decreasing possible adverse effects; there were no person who reported other symptoms followed 4 weeks from the trial. Results: In the NPMCI group, data analysis indicated statistical differences between the PA mobilization interventions in NDI and BDS-K; even though, pain was reduced in VAS, this is not a significantly differ. In the NPMD group, data analysis represented statistical differences between the PA mobilization interventions in NDI, VAS and BDS-K; the scores were represented to be increased or the pain got relief. Conclusions: PA mobilization techniques according to Maitland concept have beneficial effects in patients with neck pain and other clinical positive effects which included neck disability, pain itself and motor function of upper extremity.

  • This paper examines how Sedgwick makes a political allegory of founding the nation in domestic terms in The Linwoods (1835). Set in the Revolutionary period, The Linwoods is a historical fiction reconstructed by the writer in order to diagnose currently controversial issues. In this aspect, Sedgwick's interest in history is genealogical in Foucaudian sense. Foucault's genealogical method provides a way of recuperating a part of history hidden, submerged, obliterated by the official history. Seen in a genealogical perspective, the story of the Linwoods can be viewed as a political allegory in order to explore political conflicts of Sedgwick's own day. Faced with the threat of national disunion presented in the Nullification Crisis of sectional conflicts and divisions, Sedgwick attempts to provide a fictional solution to the first serious challenge to the U. S. Constitution. Going back to the times around the American Revolution, Sedgwick emphasizes how strenuously the American Constitution of America was formed as the outcome of the war against the tyranny of Britain, and how the Union was made on the basis of the cooperation between the States. By posing a contrast of political positions between family members, Sedgwick imagines a family/nation that allows diverse political positions. The conclusion of a diversity of marriages between man and woman who agree to be united after overcoming their differences in political affiliations seems to show her conservative proclivity to support the Union. However, by emphasizing the principles of freedom and equality represented by the significant role of Isabella and Rose, an African-American slave, in the victory of the American Revolution, Sedgwick also supports the spirit of the Jacksonian American democracy.

  • Objectives: Given the real problems at industrial sites related to the Serious Accident Punishment Act (SAPA), it has become controversial as a particularly important issue in terms of occupational safety and health. I intend to examine in detail what are the problems and how to approach them. Methods: The contents of SAPA were reviewed focusing on whether its provisions conform to the principles of occupational safety and health, whether they fit the related legal theory, and whether they are effective for accident prevention. The purpose of this study is to examine whether there is a problem with SAPA from the perspective of the effectiveness of accident prevention by combining occupational safety & health management theory, and legal theory. Results: In order to ensure the effectiveness of SAPA, it should be revised to increase the predictability and implementation of safety and health measure standards. Otherwise, it is expected that there will be not only economic and social costs in the short term, but also side effects that disrupt the safety law system, resulting in a considerable number of post-mortem conditions in the mid- to long term. Conclusions: It is easy to see in comparative law that raising the legal punishment alone does not have the effect of preventing industrial accidents. SAPA should be revised as soon as possible in the direction of faithfully and elaborately reorganizing the standards for safety and health measures.

  • Objectives: The health system reform process is highly political and controversial, and in most cases, it fails to realize its intended goals. This study was conducted to synthesize factors underlying the failure of health system reforms. Methods: In this systematic review and meta-synthesis, we searched 9 international and regional databases to identify qualitative and mixed-methods studies published up to December 2019. Using thematic synthesis, we analyzed the data. We utilized the Standards for Reporting Qualitative Research checklist for quality assessment. Results: After application of the inclusion and exclusion criteria, 40 of 1837 articles were included in the content analysis. The identified factors were organized into 7 main themes and 32 sub-themes. The main themes included: (1) reforms initiators' attitudes and knowledge; (2) weakness of political support; (3) lack of interest group support; (4) insufficient comprehensiveness of the reform; (5) problems related to the implementation of the reform; (6) harmful consequences of reform implementation; and (7) the political, economic, cultural, and social conditions of the society in which the reform takes place. Conclusions: Health system reform is a deep and extensive process, and shortcomings and weaknesses in each step have overcome health reform attempts in many countries. Awareness of these failure factors and appropriate responses to these issues can help policymakers properly plan and implement future reform programs and achieve the ultimate goals of reform: to improve the quantity and quality of health services and the health of society.

  • 본 연구는 지오파크(Geopark)에 대한 개념과 탄생 과정 그리고 지리학 분야에서의 지오파크 활동 등을 고찰하고, 현재 논란이 되고 있는 지오파크 명칭 문제를 논의한다. 지오파크는 세계지리학연합(IGU)과 세계지질학연합(IUGS)의 상호 협력관계로 출발한 것이다. 그런데 우리나라에서는 '지질공원법'이란 체계를 이용하여 특정 분야에서만 지오파크를 논의하려는 부분은 매우 잘못된 것이다. 지오파크에서의 활동은 지역의 지형·지질을 비롯한 자연물의 보전이라는 측면을 가지고 있다. 지오파크는 어느 특정 학문 분야의 전유물이 아니다. 따라서 지오파크 태동기에 있는 우리나라에서는 지오파크 명칭에 대한 논의와 합의가 선결 과제라고 생각한다.
