This article illuminates the relationship between the human being and the surrounding things by referring to the philosophy of Martin Heidegger and Maurice Merleau-Ponty. Criticizing our habitual approaches to apprehending 'what a thing is,' the two thinkers elucidate how 'what a thing is' can be understood only in conjunction with situations in the everyday and how humanity is joined with the qualities of the thing. In addition to the situated-ness of a thing, this article demonstrates the situated-ness of the human being, too, by referring to the notion of the horizon in the tradition of phenomenology. The last part of the paper discusses the basic premises of sustainability in reference to the situated-ness of both things and human beings. Framing natural things such as light as the alternative sources of energy propagandized in sustainability seems progressive. However, this attitude maintains fundamentally the same instrumental attitude we had towards nature, an attitude that has caused the current ecological crisis. By pointing this out, this article seeks to shape a ground for a broad spectrum of sustainability that embraces non-instrumental dimensions such as the practical, the ethical and the spiritual. This article also points out the limits of some of the currently available versions of ecology such as Shallow Ecology and Deep Ecology. In so doing, it seeks to lay out the parameters that any future version of sustainability and ecology needs to address.

In this paper, we introduced a new asymptotic pairwise negatively dependent(APND) structure of stochastic processes. We are also important to know the degree of APND-ness and to compare pairs of stochastic vectors as to their APND-ness. So, we introduced a definitions and some basic properties of APND ordering. Some preservation results of APND ordering are derived. Finally, we shown some examples and applications.

한국인들에게서 보이는 집단주의의 모습은 서양 이론에서 정의한 집단주의(collectivism)와는 차이가 있다는 주장이 제기되고 있다. 이 연구는 한국인들의 집단주의 정서, 즉 '우리성(we-ness)'의 개념이 가지는 하부차원을 규명하고, 이러한 '우리성'이 커뮤니케이션 행위에 미치는 영향을 살펴보고자 하였다. 연구 결과 한국적 집단주의인 '우리성'은 심리적지지, 집단이기주의, 집단회의주의, 개인희생, 집단지향, 정서적 친밀감의 6개 차원으로 구성되어 있었으며, 이는 크게 긍정적 집단주의(심리적지지, 집단지향, 정서적 친밀감)와 부정적 집단주의(집단이기주의, 집단회의주의, 개인희생)로 나뉠 수 있었다. 긍정적 집단주의와 부정적 집단주의가 커뮤니케이션 행위에 미치는 영향을 검증한 결과, 전반적으로 긍정적 집단주의는 건설적 커뮤니케이션 행위에, 부정적 집단주의는 비건설적 커뮤니케이션 행위에 영향을 미치고 있었다.

본 연구에서는 K-리그 경기 관람객들이 부족한 원인을 보다 소비자 중심적 관점에서 찾아내고 그 해결책을 제시하는데 목적을 두었다. 이를 위해 선행연구들에 기초하여 K-리그의 관람객 증대방안을 이중경로 모델을 통해 제시하였다. 첫 번째 경로는 K-리그 경기 자체보다는 경기 외적 요소에 대한 소비자 반응으로 K-리그에 대한 소비자들의 관계적, 대인적 관점을 설명하고 있으며 팬들간의 우리의식을 다루었다(가설 1, 가설 2). 두 번째 경로는 K-리그 경기 자체에 대한 소비자 반응으로 K-리그 경기에 대한 소비자들의 개인적 관점을 설명하고 있다(가설 3, 가설 4). 설문조사를 통한 자료수집 후 구조방정식 모형을 통해 가설 검증을 실시하였으며, 검증 결과 4개 가설 모두 지지됨을 확인하였다. 즉 특정 K-리그 팀 팬들간의 우리의식이 클수록 해당 팀에 대한 애호도가 증가하며(가설 1), 이러한 팀애호도가 강할수록 해당 팀의 경기 관람의향도 증가함(가설 2)을 확인할 수 있었다. 또한 두 번째 경로를 구성하는 가설들의 검증에서도 경기에서 경험하는 플로우가 강할수록 경기 자체에 대한 만족도가 증가하며(가설 3), 경기 자체에 대한 만족도가 증가할수록 해당 팀의 경기 관람의향도 증가함(가설 4)을 확인하였다. 연구결과는 이중경로 모형을 통해 K-리그와 관련한 응원연구의 확장을 기했다는 점과 우리의식의 중요성 제기를 통해 K-리그 구단들의 팬 커뮤니티 구축과 지원 필요성을 강조하고 있다는 점을 연구의의로 정리하고 있다.

Purpose: Recently, non-exposure simple suturing endoscopic full-thickness resection (NESS-EFTR) was developed to prevent tumor exposure to the peritoneal cavity. This study aimed to evaluate the feasibility of NESS-EFTR with sentinel basin dissection for early gastric cancer (EGC). Materials and Methods: This was the prospective SENORITA 3 pilot. From July 2017 to January 2018, 20 patients with EGC smaller than 3 cm without an absolute indication for endoscopic submucosal dissection were enrolled. The sentinel basin was detected using Tc^99m-phytate and indocyanine green, and the NESS-EFTR procedure was performed when all sentinel basin nodes were tumor-free on frozen pathologic examination. We evaluated the complete resection and intraoperative perforation rates as well as the incidence of postoperative complications. Results: Among the 20 enrolled patients, one dropped out due to large tumor size, while another underwent conventional laparoscopic gastrectomy due to metastatic sentinel lymph nodes. All NESS-EFTR procedures were performed in 17 of the 18 other patients (94.4%) without conversion, and the complete resection rate was 83.3% (15/18). The intraoperative perforation rate was 27.8% (5/18), and endoscopic clipping or laparoscopic suturing or stapling was performed at the perforation site. There was one case of postoperative complications treated with endoscopic clipping; the others were discharged without any event. Conclusions: NESS-EFTR with sentinel basin dissection is a technically challenging procedure that obtains safe margins, prevents intraoperative perforation, and may be a treatment option for EGC after additional experience.

본 연구는 초등학교 교사가 인식하는 우리성의 구성요인을 탐색하여 한국 고유의 관계성에 기반을 둔 새로운 지표로 교원문화와 학교의 조직문화를 설명하고 개선하는데 활용하고자 하였다. 이에 기존에 개발된 우리성 측정 도구를 한 도구를 토대로 초등학교 교사의 상황에 맞게 재구성하여 사용하였다. 본 연구는 2018년 12월 1부터 27까지 B지역과 K지역에 소재한 초등학교 교사 206명을 대상으로 자료를 수집하였으며, SPSS 23과 Mplus 7.1 프로그램을 활용하여 탐색적 요인분석, 확인적 요인분석을 실시하였다. 연구결과 초등학교 교사들이 인식하는 우리성 인식구조는 '심리적 안녕감', '배려적 관계', '윤리적 정당성', '시간의 공유'이며, 이러한 하위요인들은 초등 교사들이 우리성을 느끼는 상황을 설명하는 데 근거를 제시하고 있다. 그리고 우리성이 개인의 관계 뿐 아니라 우리 반, 우리 학교 등 교육기관과의 관계로 확장될 수 있음을 고려할 때 한국적 관계성을 기반으로 한 학교문화와 교직문화 형성을 위한 방안을 제시하는 데에도 활용될 수 있을 것이라 판단된다. 하지만 본 연구는 초등 교사를 대상으로 진행한 인식조사에 기초한 접근을 하고 있어 유아교유기관이나 중등, 고등교육기관에 적용하기에는 문제가 있다. 또한 본 연구는 통계적 분석을 통해 하위요인을 탐색한 양적연구이다. 양적연구의 결과는 학교구성원들과의 면담 등을 통해 정교화 하거나 현장에서의 사례연구를 통해 검증하는 후속연구가 필요하다.

The events at the Fukushima Daiichi Nuclear Power Station in March 2011 point out, among other matters, that concurrent accidents at multiple units of a site can occur in reality. Although site risk has been deterministically considered to some extent in nuclear power plant siting and design, potential occurrence of multi-unit accident sequences at a site was not investigated in sufficient detail thus far in the nuclear power community. Therefore, there is considerable worldwide interest and research effort directed toward multi-unit site risk assessment, especially in the countries with high-density nuclear-power-plant sites such as Korea. As the technique of probabilistic safety assessment (PSA) has been successfully applied to evaluate the risk associated with operation of nuclear power plants in the past several decades, the PSA having primarily focused on single-unit risks is now being extended to the multi-unit PSA. In this paper we first characterize the site risk with explicit consideration of the risk associated with spent fuel pools as well as the reactor risks. The status of multi-unit risk assessment is discussed next, followed by a description of the emerging issues relevant to the multi-unit risk evaluation from a practical standpoint.

The purpose of this study is examining a circulation and conflict of concepts and logics of the $Chos{\check{o}}n$-ness by analysing the $Chos{\check{o}}n$ national character and $Chos{\check{o}}n$ aesthetic consciousness. As entering the modern period, we understood the nations as a unit of the artistic awareness. So, national art is defined as a national character expression from this period. The $Chos{\check{o}}n$ aesthetic consciousness by raising in this period, which is connected with the discourse of national character, carry out a discussional practice defining the Korean originality. However, there is a circulation and conflict of concepts and logics about the $Chos{\check{o}}n$ aesthetic consciousness in the process of a discussion. For the most representative examples are 'the white-clad folk' and 'the beauty of sorrow'. An Hwak and Yanagi Muneyoshi are representative debaters who try to establish the $Chos{\check{o}}n$-ness and their discussion supports these facts. As An Hwak regressing of the respect for high antiquity, he demolished the historical character from the $Chos{\check{o}}n$-ness and overlooked aesthetic differences by a periodical change. Yanagi Muneyoshi totally separates arts from politics and disposes of Korean arts in an abstract timeless-space. The function of such an early-modern period's discourse about $Chos{\check{o}}n$ aesthetic consciousness is that $Chos{\check{o}}n$ national character makes the dehistoricization and depoliticization.

A number of recent studies have claimed that the double red clump observed in the Milky Way bulge is a consequence of an X-shaped structure. In particular, Ness & Lang (2016) report a direct detection of a faint X-shaped structure in the bulge from the residual map of the Wide-Field Infrared Survey Explorer (WISE) image. Here we show, however, that their result is seriously affected by a bulge model subtracted from the original image. When a boxy bulge model is subtracted, instead of a simple exponential bulge model as has been done by Ness & Lang, we find that most of the X-shaped structure in the residuals disappears. Furthermore, even if real, the stellar density in the claimed X-shaped structure appears to be too low to be observed as a strong double red clump at $l=0^{\circ}$
