Hybrid grouper(Epinephelus fuscoguttatus ♀×E. lanceolatus ♂) (mean weight 25.7±3.5g, mean length 11.2±0.9cm) were exposed to different ammonia concentrations of 0, 5, 10, 20, and 40mg L^-1 for 96 hours. The hematological hematocrit and hemoglobin parameters of the hybrid grouper were significantly decreased by 20 mg L^-1 ammonia exposure. In the organic plasma components, calcium was significantly decreased, whereas there was no change in magnesium. In the organic plasma components, the glucose and cholesterol values of the hybrid grouper were significantly increased by ammonia exposure. In the enzymatic plasma components, the ALP(Alkaline phosphatase) value of the hybrid grouper was also significantly increased by ammonia exposure. The results of this study demonstrate that acute ammonia exposure to hybrid grouper induced changes in hematological parameters and plasma components. Therefore, acute ammonia exposure over 20 mg L^-1 appears to be toxic to hybrid grouper and the results can be used as a major indicator in breeding hybrid grouper. 본 실험에서 암모니아 급성 노출은 대왕범바리의 혈액학적 성상 및 혈장 성분에 유의적 변화를 나타내었다. 본 실험의 결과 20mg L^-1 이상의 급성 암모니아 노출은 대왕범바리의 혈액학적 성상 및 혈장 성분에 영향을 주어 생리적 변화를 일으키며, 40mg L^-1의 급성 암모니아 농도는 대량 폐사를 유발할 수 있음을 나타낸다. 향후 대왕범바리 바이오플락 양식기술 적용을 위한 양식연구에 이러한 결과를 지표로 활용할 수 있을 것이다.

Purpose: Papillary thyroid carcinoma is the most common malignant tumor originating from the thyroid. The recent increase in frequency of thyroid ultrasonography is increasing the diagnostic rate of thyroid cancer, especially of the small-sized cancer. The appropriate extent of surgery for thyroid micropapillary carcinoma is still under debate, and bilaterality of the tumor may be an important factor determining the extent. Therefore, this study analyzed the clinicopathologic factors related to tumor bilaterality in order to help decide the extent of treatment. Methods: Subjects included 134 patients who received total thyroidectomy and central neck lymph node dissection at Wonju Christian Hospital under the diagnosis of thyroid micropapillary cancer from January 1<SUP>st</SUP>, 1994 to December 31<SUP>st</SUP>, 2009. The frequency of bilateral tumor among the subjects were studied, and the relationship between bilaterality and clinicopathologic factors, including patients' gender, age, tumor size, multiple mass in single lobe, capsule invasion, extrathyroidal extension, lymphovascular space invasion, central neck node invasion and lateral neck node invasion was analyzed. Results: There were 32 cases (23.9%) of bilateral tumor. Statistically significant factors related to bilaterality included two or more mass in a single lobe, perithyroidal soft tissue invasion. Conclusion: When we plan thyroidectomy for thyroid micropapillary cancer, one cannot rule out the possibility of bilateral thyroid micropapillary cancer in patients with clinicopathologic factors related to bilaterality. Closer preoperative examination is thought to be required for such patients. (Korean J Endocrine Surg 2011;11:18-21)

의례를 통한 심성함양 : 메를로-퐁티의 관점을 중심으로

김광민(Kwang-Min Kim) 한국도덕교육학회 2018 道德敎育硏究 Vol.30 No.3

이 글의 목적은 의례를 통한 심성함양의 기제를 설명하는 것이다. 의례는 몸을 중심으로 하여 이루어지는 활동이며, 따라서 심성함양의 매체와 관련지어 생각할 때, 그것은 ‘비언어적 상징’에 속한다. 의례를 통한 심성의 함양은 특히 동양적 전통에서 충분히 강조되어 왔지만, 그 기제가 아직 명확하게 드러나 있지는 않다. 몸을 통한 심성함양의 기제는 지각에 초점을 둘 때 보다 분명하게 드러날 수 있다. 이 글은 지각에 관하여 심도 있는 분석을 해낸 현상학자 메를로-퐁티의 관점을 참고하여 지각은 ‘의식’ 이전에 ‘몸’에 근거한 인식이라는 점을 탐색하였다. 메를로-퐁티의 관점에서 지각은 대상과 주체의 어느 한편을 중심으로 하여 설명될 수 없으며, 지각의 사태는 이미 주체와 대상이 함께 참여하는 사태로 이해될 수 있다. 그러나 의례를 통한 심성의 함양을 설명하려면, 주체와 대상의 비분리를 한 걸음 더 밀고 나아가, 性과 理의 동일성을 말하지 않으면 안 된다. 상징이 개념의 매개 없이 심성에 직접 작용한다는 점을 염두에 두면, 의례적 사태는 몸을 통하여 심성을 직접 일깨우도록 고안된 사태로 이해될 수 있다. The purpose of this study is to explain the mechanism of cultivation of mind through ritual. The ritual is based on the body rather than the speculative thought, and when it focuses on the medium of cultivation, it belongs to the non-verbal symbol distinguished from concept . The cultivation of mind through ritual has been emphasized enough, especially in oriental tradition, but its mechanism has not been fully explained yet. The mechanism of cultivation of mind through the body can become more evident when focusing on perception. This study referred to phenomenologist Merleau-Ponty s point of view who has made in-depth analysis of perception, and explored that perception is a body-based knowing before consciousness. In the view of Merleau-Ponty, perception can not be explained by focusing on either the object or the subject, and the situation of perception can be understood as a situation in which the subject and object participate together. However, in order to explain the cultivation of mind through ritual, we must push the non-separation of subject and object one step further and tell the identity of nature[hsing, 性] and principle[li, 理]. Considering that the symbol acts directly on the mind without the mediation of the concept, the ritual situation can be understood as a situation designed to directly awaken nature[hsing, 性] through the body.

김광민 ( Kwang Min Kim ) 한국기초조형학회 2011 기초조형학연구 Vol.12 No.1

오늘날 급변하는 디지털정보의 범람 속에서 이루어지는 대학의 기초시각디자인교육이 효과적이고 흥미 있는 학습참여가 이루어지기 위해, 롤플레잉 게임에서 이루어지는 퀘스트적인 전개 형식에 스토리텔링기법을 적용한 퀘스트텔링을 통하여 학생들의 마음속의 경험적인 내용을 지각하여 발현 가능한 아이디어로 구체화시킬 수 있는 ``구체적인 조형행위 구현``에 관한 창조적 활동이 흥미롭게 이루어질 수 있도록 하는 것에 있다. 여기에는 언어적 메시지의 유추와 함께 도상적인 메시지로 일치시키는 내용과 감성의 조형행위가 담겨있다. 현대의 시대적 변화인 범람하는 정보의 증가는 보편적인 정보가 되어 커뮤니케이션의 객관적인 공유의 의미로서 공감을 이끌어내기에 너무 광범위하지만 한편으로는 이런 광대한 정보들과 그 정보들의 구성적인 조합들을 통해 ``설득``과 ``공감의 소통`` 역시 확대될 수 있음을 의미한다. 본 연구는 대학에서 기초시각디자인교육이 필수 기초 조형학습으로 의도하는 메시지의 창조행위를 능동적인 감정과 느낌을 다양하게 표현 할 수 있는 흥미 있는 교육법의 적용과 그 학습체계의 가능성을 구체적이고 체계적으로 과제수행의지를 형성할 수 있는 교육법으로의 방향성 및 적용사려를 보여주는데 그 목적을 두고 있다. 또한 현재의 사실에 근거한 학생들의 개인적인 경험에 담겨있는 정서적인 기억의 이미지를 디자인의 기초적인 학습을 통해, 무엇보다 능동적으로 학생들의 경험 속에 지각되어있는 시각적 이미지 속에 담겨진 핵심적인 이야기들을 선택적으로 재조합하고 결합시켜 정서적 반응을 유발할 수 있는 창조행위에 능동적으로 참여할 수 있도록 하고자 하는 것이다. Under the flooding digital information that changes rapidly in recent, the quest-telling that combines the quest-like form in role-playing game and story telling method to facilitate effective and interesting learning in basic graphic design education at college is aimed to guide the students to perceive the experiential matters in their mind. It is also aimed to make more interesting he creative activities in ``realizing specific plastic arts activities`` that can be specified into the realizable ideas. It includes the contents to tune to the iconic messages along with the verbal messages as well as the emotional plastic arts activities. The temporal change in modern society, that is, the increase in the flooding information becomes universal information so it is too wide to derive out the sympathy in terms of objective sharing. On the contrary, however, it means that ``persuasion`` and ``sympathetic communication can also be expanded through such a wide range of information and their structural combination. This study is aimed to apply an interesting teaching method to express the active emotions and feelings in the creative activities of the intended message through the essential basic plastic arts learning in the basic graphic design education at college and to demonstrate the direction to build the possibility of the learning system into more specific and systematic task performance will and their application cases. In addition, this study is aimed to facilitate the students to actively participate in the creative activities to induce their emotional responses by selectively recombining and mixing the images in the emotional memories contained in their personal experiences based on the current facts, especially the core stories contained in the graphic image actively perceived by their experiences through the basic leaning of design.

김광민(Kwang-Min Kim),김아롱(A-Rong Kim),김진근(Jin-Geun Kim),박민원(Minwon Park),유인근(In-Keun Yu),이상진(Sangjin Lee) 대한전기학회 2010 대한전기학회 학술대회 논문집 Vol.2010 No.7

The PSCAD/EMTDC (Power System Computer Aided Design/ElectroMagnetic Transient DC) is generally used to simulate a power network. However, it is difficult to analyze the characteristics of power devices, such as magnetic field, temperature variation, and stress using EMTDC. MATLAB is able to analyze the characteristics of power devices using numeric formula and interconnect with other software packages. Similarly, EMTDC also allows communication through its FORTRAN interface. This paper describes the combination of EMTDC and MATLAB for UPQC-SMES (Unified Power Quality Conditioner-Superconducting Magnetic Energy Storage) system simulation and the results are discussed in detail.

불교 수행이론과 메타프락시스

김광민(Kwang-Min Kim) 한국도덕교육학회 2020 道德敎育硏究 Vol.32 No.2

The purpose of this paper is to explore the possibility of interpreting Buddhist practice from the viewpoint of metapraxis. This possibility arises from the understanding that the nature of Suchness[Mind-Nature] identified in Buddhism can be understood as being established through Buddhist practice. In this paper, Buddhist practice is understood based on two principles of practice: balanced practice of concentration & contemplation[止觀雙修] and gradual cultivation followed by sudden enlightenment[頓悟漸修]. The former principle that reveals the unique characteristics of Buddhist practice focuses on simultaneity of concentration and contemplation. The latter principle focuses on the process of Buddhist practice, and is concerned with the relationship between the process and the purpose of Buddhist practice. Sudden enlightenment as the standard for Buddhist practice occurs in the process of practice, and the practice becomes more complete by sudden enlightenment. The theory of Buddhist practice can be clearly understood from the viewpoint of metapraxis, and beyond that, it can be regarded as a model of metapraxis. 본 논문의 목적은 불교의 수행을 메타프락시스적 관점에서 해석할 가능성을 탐색하는 데에 있다. 이 가능성은 불교수행에서 확인되는 심성의 성격, 즉 심성은 수행을 통하여 확립되는 것으로 이해될 수 있다는 데에서 생긴다. 이 글에서는 불교수행을 지관쌍수(止觀雙修)와 돈오점수(頓悟漸修)의 두 가지 수행원리를 중심으로 탐색하였다. 지관쌍수는 ‘그침’(止)의 수행과 ‘살핌’(觀)의 수행이 동시에 이루어져야 할 것을 역설하는 수행의 원리로서, 수행의 ‘내용’에 초점을 두면서 불교수행의 독특한 성격을 드러낸다. 한편 돈오점수는 수행의 ‘과정’에 주목하면서, 수행의 과정과 수행의 목적과의 관련을 문제 삼는다. 수행의 기준으로서의 돈오는 수행의 과정에서 생기며, 그 기준은 수행의 과정을 통하여 확립된다. 불교의 수행이론은 메타프락시스적 관점에서 선명하게 드러날 수 있으며, 그 이상으로, 메타프락시스의 전형으로 간주될 가능성이 있다.

The characteristics of the Superconducting Magnetic Energy Storage (SMES) system are faster response, longer life time, more economical, and environment friendly than other Uninterruptible Power Supply (UPS) using battery. Fast charge and discharge time of SMES system can provide powerful performance of improving power quality in the grid. In order to demonstrate the effectiveness of SMES, the authors make a 10kJ SMES system for connection with RTDS (Real Time Digital Simulator). Because the characteristics of superconducting magnet are very important in SMES system, the necessary items such as thermal characteristic, mechanical stress and protection circuit should be considered. In this paper, the authors experimented thermal characteristics of the 10kJ SMES system. The experiment was accomplished using a simulation coils made of aluminium. It has same dimension of the 10kJ class HTS SMES coil. The coil was cooled with GM (Gifford -McMahon) cryocooler through the OFHC (Oxgen Free High thermal Conductivity) conduction bar. The test results of cool down and heat loads characteristics of the simulation coils are described in detail.
