이광진,정영수,Lee, Kwangjin,Jung, Youngsoo 한국건설관리학회 2016 건설관리 : 한국건설관리학회 학회지 Vol.17 No.6

과거 1960~70년대에 급격한 경제발전으로 인하여 국내에는 수많은 건물이 건설되었으며, 특히 2000년 이후에는 대형화, 첨단화된 수많은 건물들이 건설이 되고 있다. 이러한 건물의 전 생애주기 비용 (Life Cycle Cost) 중, 운영 및 유지관리 단계 비용은 전체의 약 85%를 차지 (Teicholz 2004)하고 있어 건축물에 대한 효율적인 자산관리가 강조된다. 하지만 운영 및 유지관리 단계에서 필요한 정보들은 초기 기획 단계부터 설계, 시공 단계를 넘어오면서 각각의 정보들의 호환이 부족하다. 단계를 거듭할수록 정보에 대한 가치는 증가하지만 정보의 상호 호환의 부족으로 인하여 비효율적인 부분이 발생하고 있다 (Foster 2011). 본 연구에서는 먼저 발주자 관점에서 자산관리의 주요 업무기능을 3개의 대분류와 19개의 중분류로 도출하였다. 다음으로는 도출한 항목들을 바탕으로 자산관리 업무량의 비중, 자산관리 업무별 소요 데이터의 비중, 그리고 생애주기 단계별로 발생하는 데이터의 비중에 대한 평가방법론을 제안함으로써, 효율적인 운영 및 유지관리를 위한 방안을 제안하였다. 마지막으로, 제안된 방법론은 공공 및 민간 기업의 사례를 바탕으로 적용성을 검토하였다. In the 1960s and 1970s when Korea experienced rapid economic growth, a considerable number of buildings were constructed in the country. And since 2000, a large number of sizable and complex buildings have been being built. Specifically, as the operation and maintenance cost alone accounts for 85% of the life cycle cost of a building, efficient Facility Management (FM) is required. However, data needed in the operation and maintenance phase are not sufficiently exchangeable with data created in other phases like the planning, design and construction phases. The upper phase has higher value of data but data exchange rate is low, resulting in inefficiency. To this end, this research derived major business functions for facility management: three categories and 19 detailed functions in classification from owner's perspective. Based on the derived items, this research proposes a methodology to evaluate the 'FM Workload', 'Facility Management (FM) Data', and 'FM Data Created in Engineering and Construction Phases' thereby analyzing plans for efficient operation and maintenance. The applicability of proposed methodology was tested by examining real-world cases of public and private companies.

미국의 환상, 혹은 환상의 미국 : 커트 앤더슨의 「환상의 땅」과 콜린 딕키의 「미확인물체」의 환상에 대하여

이광진(Kwangjin Lee) 한국인문사회과학회 2021 현상과 인식 Vol.45 No.3

본 논문은 최근 미국 사회의 변화를 이해하는 하나로 미국문화의 개인주의적 환상을 주요하게 다루는 커트 앤더슨이 2017년에 출판한 「환상의 땅: 어떻게 미국이 엉망진창이 되었는가? 500년의 역사」(2017)와 콜린 딕키의 「미확인물체: 신화적인 괴물, 외계인 조우, 그리고 설명되지 않은 것들에 대한 우리의 강박」(2020)을 살펴본다. 앤더슨의 책은 500년의 개신교를 중심으로 미국의 문화를 역사적 접근법으로 살피며 개신교의 교리가 미국에 개인주의적 환상의 근간을 형성했고, 미국 역사를 통해서 그 미국적 환상이 종교뿐만 아니라 다양한 영역에서 영향을 끼치며 특히 21세기 전후 강한 영향력을 행사하고 있다고 분석한다. 본 논문에서는 앤더슨의 접근법과 논지 전개에 크고 작은 오류들의 일부, 특히 이 저서가 독특하게 미국 역사와 연결한 초기 개신교에 집중하여 비판한다. 과도하게 광범위한 시대와 대상을 선정하여 설득력이 부족한 앤더슨과는 달리 딕키의 저서는 그 다루는 범위가 적당하게 제한적이다. 상상의 괴물과 미확인비행물체(UFO)와 외계인이라는 두 주제에 집중하여 사례들을 하나씩 다루며 미국인들이 설명되지 않은 것들에 집착하는 이유를 설득력 있게 설명한다. 본 논문에서는 딕키의 주장에 전체적으로 동의하면서 몇 가지 아쉬운 부분을 지적한다. This paper reviews two recently published books on American fantasy, which may help us to understand more the change of American culture at the turn of the twenty-first century: Kurt Andersen’s Fantasyland: How America Went Haywire: A 500-Year History (1917) and Colin Dickey’s The Unidentified: Mythical Monsters, Alien Encounters, and Our Obsession with the Unexplained (2020). Andersen takes historical approach on the topic in order to show the persistence of fantasy in American culture, particularly focusing on the Protestantism that Martin Luther started in 1517, the year that renders America’s fantasy history 500 years. He argues the fantasy of individualistic Protestantism formed the basis of American culture, and expanded its influence on Americans throughout its history. The reviewer judges that this book is quite problematic in many aspects and provides some examples of his criticism on the book, especially focusing on his view on the early period Protestantism. Different from Andersen, whose attempt to cover such a long time span and so diverse topics overwhelms the author out of control, Dickey reasonably narrows down his main topic to mythical monsters and UFO/alien. Dealing several cases of the two topics one by one, he persuasively explains why Americans are so obsessed with them. The reviewer mainly agrees with his arguments but criticizes some minor points that would have made the book better if the author paid more attention to them.

문학과 경영학: 마크 트웨인의『아더 왕궁의 커넷티컷 양키』에 나타난 동기 전쟁

이광진(Kwangjin Lee) 한국영미문학교육학회 2012 영미문학교육 Vol.16 No.2

This paper analyzes characteristics of the protagonist of Mark Twain’s A Connecticut Yankee in King Arthur’s Court and those of the people and the society of Arthur’s kingdom in the sixth century in which he was thrown by a mysterious force. In order to figure out the characteristics, it applies a theory from Organizational Behavior, a branch of the discipline of Management. David C. McClelland’s “achievement motivation theory,” which categorizes human motivations into need for Achievement (n Ach), need for Power (n Pow), and need for Affiliation (n Aff), provides a useful tool to understand human characteristics in terms of motivation. The theory shows that Hank, the protagonist and the man from the nineteenth century America, has high n Ach whereas the society of Arthur’s Kingdom has very low n Ach while the Church and the aristocrats have high n Pow. The paper argues that what Hank is essentially doing is converting the low n Ach society into high n Ach one. In the course of the conversion (or revolution), he conflicts with the Church and the aristocrats that are manipulative and want to keep the society low n Ach. From this perspective, his revolution is, in essence, the motivation war—war between two different motivations. To win the war against two formidable forces, Hank creates his own force, the enlightened people whom he trains and educates with his advanced knowledge and technology. However, it turns out that his people fail to resist the Church’s interdict, and Hank’s enterprise eventually fails. This paper attempts to find the cause of the failure using McClelland’s theory. In addition, it also shows that Hank himself changes in the latter part of the fiction. His change of the characteristics provides a possible explanation why he falls into the spell of Merlin’s magic which has no effect on him before his change.

무의미한 연명치료와 헌법상 권리

이광진(Lee, KwangJin) 한양법학회 2010 漢陽法學 Vol.31 No.-

Recently, the problem with the right to dignity is the interest things in our society. The issue erupted into Korean public consciousness on May 21, 2009, with the news that the Supreme Court upheld that the patient entered irrecoverable death stage and her intention for discontinuance of life-extending treatment can be inferred as an element for discontinuing life-extending treatment. In the United States, Oregon state enacted the Death with Dignity Act in 1994, and Washington state adopted the Natural Death Act in 2009. The former allows terminally ill adults seeking to end their life to request lethal doses of medication from medical physicians. The latter allows the adult persons have the fundamental right to control the decisions relating to the rendering of their own health care, including the decision to have life-sustaining treatment withhold or withdraw in instance of a terminal condition or permanent unconscious condition. Now there lively dispute of legal policy on the preconditions and concrete procedure of natural death act and dignity death act in the Korea National Assembly. Through the legislation of natural death act, we should prepare some circumstances to respect patient’s autonomy on the right to die. We get good point of suggestion in the bill of the right to die with dignity or natural death.

종교학과 문화인류학의 신화와 역사 개념으로 분석한 허먼 멜빌의 「모비딕」의 구조

이광진(Kwangjin Lee) 한국인문사회과학회 2021 현상과 인식 Vol.45 No.4

본 논문은 멀치아 엘리아데, 프로니스로프 말리노프스키, 정 진홍과 같은 중교학과 문화인류학 분야의 학자들이 사용하는 신화와 역사의 개념을 활용하여 허먼 멜빌의 「모비딕」의 구조를 분석한다. 특히, 엘리아데와 정 진홍은 역사를 사람들에 의해 참과 거짓이 구분 가능한 하나의 사실(현실)로 정의하는 반면 신화는 참과 거짓으로 구분될 수 없는 또 다른 하나의 사실(현실)로 정의한다. 엘리아데는 고대인들이 일상에서 역사를 적극적으로 거부하고 제의를 통해 그들의 신화의 원형에 회귀하여 참여하려고 한다고 주장한다. 그들에 의하면, 신화는 사회에 도덕성이나 윤리 같은 기본적인 것을 제공하기도 하지만 사람들에게 일상에서 벌어지는 일들의 의미를 던져주기도 한다. 본 논문은 「모비딕」에 등장하는 인물들의 이름을 분석함으로써 이 이름들이 구약성경에서 차용된 이름과 그렇지 않은 이름의 두 부류로 나뉘는데, 이 구분이 저자에 의해 의도된 것이라는 증거를 바탕으로, 작품에서 가장 중요한 두 인물인 이스마엘과 아합(성경에서 그 이름을 차용한 인물들)이 인생의 의미를 추구하는 반면, 아합의 대척점에 있는 스타벅(성경에서 이름을 차용하지 않은 인물)은 이스마엘과 아합이 추구하는 것을 거부하고 향유고래로부터 기름을 모으는 작업에만 전념하기를 원한다. 이 글은 또한 다른 인물들의 의미와 역할에 대해서도 분석한다. This study attempts to analyze the notoriously complex structure of Herman Melville’s Moby-Dick. It adopts the concepts of myth and history, which some scholars—particularly Mircea Eliade, Bronislaw Malinowski, and Chin-Hong Chung—in Religious Studies and Cultural Anthropology use for their studies. Particularly, Eliade and Chung define history as a kind of reality which can be identified as true or false by people, while myth is another kind of reality that cannot be judged as true or false by them. Eliade asserts that the ancient peoples rejected history in their everyday lives while they actively wanted to participate in the archetypes by the repetition of ritual ceremonies. According to them, myth provides a society not only with fundamental things such as morality and ethics but also with the meaning of events that happen to people. Analyzing the names of major and minor characters of Moby-Dick, this study suggests that the names can be divided into two groups: those from the Old Testament and those not from it. An evidence is presented that this division seems to be intended by the author, and Ishmael and Ahab—the most important names from the Bible—pursue meaning of life while Starbuck—the major antithesis of Ahab—denies what Ishmael and Ahab pursue but wants to stick to the business of gathering oil from sperm whales. It also shows what other minor characters’ names stand for.

100㎿급 순산소 미분탄 발전 플랜트의 비교 성능 해석

이광진(Kwangjin Lee),김성은(Sungeun Kim),최상민(Sangmin Choi),김태형(Tae-hyung Kim) 한국연소학회 2009 KOSCOSYMPOSIUM논문집 Vol.- No.39

This study presents the analysis and the approach of its for commercial scale oxy-coal-fired power plant. Also, it is possible to support feasible study and data of a design for ongoing various studies of oxy-coal-fired generation system using this study. For an approach of the system, we suggest a method of simplification and an approach, and an evaluation with selected cases. The system is simply divided into four blocks; air separation unit (ASU), carbon dioxide processing unit (CPU), water-steam side, and air-gas side. Using the concept of system-separation, the main variables of the system can be chosen such as energy consumption of ASU and CPU and flue gas recirculation (FGR) rate. Independent blocks and inter-dependent blocks are suggested as the method of an approach. Performance analysis is performed based on the system heat and mass balance and simple performance parameters such as the fuel to power efficiency, the exergy analysis based on the 2nd law of thermodynamics and variation of gas composition with cases. Cases are selected for comparative evaluation, based on the site-specific requirements.

A Proposed Approach for Performance Modeling of Thermodynamical Assessment to Realize an Oxy-coal fired Power Plant

Kwangjin Lee(이광진),Sangmin Choi(최상민),Taehyung Kim(김태형) 한국연소학회 2008 KOSCOSYMPOSIUM논문집 Vol.- No.-

We are working on one of methods proposed on technology of carbon dioxide capture and storage, which is targeted at coal-firing power plant due to the increase in carbon dioxide which is the main cause of global warming. Oxy-coal fired power plant of systems is classified as oxygen production, oxygen combustion, boiler, desulfuration and collection, and carbon dioxide recovery. It needs 'oxygen production and optimization of carbon dioxide recovery,' and 'optimization of flue gas recirculation' to analyze the system of the thermodynamic assessment. Young Dong power plant part 1 as our case of research is separated from the same condition of existing steam cycle, and the condition of steam cycle changed on ultra super critical working condition. We plan to do the optimization of flue gas recirculation depending on each condition, which is necessary for the thermodynamic assessment, and further more an exergy analysis is under consideration based on heat and mass balance. A complicated oxy-coal fired generation system is divided by four parts: air separation unit (ASU), air-gas, water-steam, and carbon dioxide compression and purification unit (CPU). Enough parameters is found out and should be optimized for abovementioned four parts. Now we are in the works for analysis of a part of water-steam, and enough working parameters in these parts are doing analysis on referring to young-dong power plant part 1 of the drawing chart and simple working conditions. The detailed working conditions are assumed because of not yet securing.
