LNG 운반선 대형 스카폴딩 모듈의 해상운송을 위한 고박 방안 연구
박명철,신상훈 대구과학대학교 국방안보연구소 2022 사회융합연구 Vol.6 No.3
Scaffolding is not a structure of a building or hull, but it is a temporary installation installed for high-place work, such as ceiling construction of a building or the inside of a tank of a ship. It is closely related to membrane LNG carriers, which are high value-added vessels in the shipbuilding field. Scaffolding plays a very important role in efficiency of work and safety of workers. Depending on how it is installed, it is a factor that has a great impact on shortening the construction period for LNG carriers, so each shipyard has made a lot of effort to develop new construction methods. The purpose of this study is to derive a lashing plan for marine transport of large modules to maximize the utility of the mounted method of the large scaffolding modules developed. The Lashing plan is a way to secure a large module on the barge for safe marine transport. The safety factor is derived for the safety of the large module and wire rope during transportation and the type, diameter and lashing position of the wire rope satisfying the safety factor are determined. It is considered that the safety of the marine transport plan was verified through hundreds of successful actual marine transports by applying the lashing plan derived from this study. 스카폴딩(scaffolding)은 건물이나 선체의 구조는 아니지만 건물의 천정공사나 선박의 탱크(tank) 내부 등 고소 작업을 위해 설치하는 임시 가설물로서, 조선분야에서는 고부가가치 선박인 멤브레인 LNG 운반선과 밀접한 관계가 있다. 스카폴딩은 작업능률과 안전성에 매우 중요한 역할을 하며, 어떻게 설치하느냐에 따라 LNG 운반선의 공사기간 단축에 큰 영향을 미치는 요소가 되므로 각 조선소마다 신공법 개발에 많은 노력을 기울여 왔다. 본 연구의 목적은 기 개발된 대형 스카폴딩 모듈의 탑재 공법의 효용성을 극대화하기 위해 대형 모듈의 해상운송을 위한 고박 방안을 도출하는 것이라 할 수 있다. 고박 방안은 안전한 수송을 위해 바지선 위에 대형 모듈을 고박하기 위한 방안으로서, 운송 중 대형 모듈과 와이어로프(wire rope)의 안전을 위한 안전계수를 선정하고, 안전계수를 만족하는 와이어로프의 종류, 직경 및 고박 위치를 결정하는 것이라 할 수 있다. 본 연구에서 도출된 고박 방안을 적용하여 수백 회에 걸친 성공적인 실제 해상운송을 통해 그 안전성은 검증되었다고 사료된다.

연구논문 : 통일과정에서 남북한교회의 활동과 윤리적 과제
박명철 한국대학선교학회 2006 대학과 선교 Vol.10 No.-
The basic purpose of this essay is to introduce the role and activities of Korean churches for reunification. This paper consists of three parts. In the first part, the author introduces and interprets a series of political events that have shaped the basic relationship between North and South Korea, between North Korea and the U.S. In the second part, the author examines the role and activities of North and South Korean churches to overcome national division, and discusses the historical meaning and limitations of them. Finally, in the third part, raising some theological questions, the author proposes some Christian ethical tasks to overcome division. To skim through this article, there have been five symbolic political events of exchange and cooperation between North and South Korea: The July 4th North-South Joint Communique(1972), the Basic Agreement between North and South Korea(1991), the Geneva Agreement(1994), and the June 15th North-South Joint Declaration (2000). Each statement reflects different issues and problems of Korean reunification in different period. Each also represents various endeavors to resolve problems within and beyond the limits of each period. To give some examples: The July 4th Joint Communique(1972), which declares three basic principles for reunification of Korea(i.e., self-reliance, peace, and national solidarity), provided a momentum for North Korea to move from the issues of class to those of nation. In the Basic Agreement(1991), North and South Korean governments concededtwo political systems in one nation and approved the scheme of gradual reunification through peaceful coexistence. The Geneva Agreemen (1994) raised a new issue of North Korean nuclear development(i.e., the issue of the weapons of mass destruction) and made military agenda central in the talk not only between North Korea and the U.S. but also between North and South Korea. By reviewing these historical development and process, the author reveals that political agreement is crucial, because it provides the institutional framework for North-South exchange and dialogue, and because it has no small impact on church activities in North and South Korea. Then, the author investigates the activities of North and South Korean churches for peace and reunification in the Korean peninsular. The author is convinced that any political view and approach to reunification requires a thorough examination from theological point of view. For this, the author introduces the activities of Korea Christian Federation(KCF), which is the sole Protestant organization in North Korea, and also of South Korean Protestant churches`` ecumenical movement, which has invigorated since the 1960s. From its inception, the KCF has been brought up in close relationship with North Korean Labor Party. The KCF began to participate actively in reunification movement since the 1970s as North Korean government began to change its "anti-Christian" policies after it came in contact with progressive Christian movements around the world(e.g., the World Council of Churches, the Vatican, and Latin American churches) and also with South Korean churches`` social activism. At that time North Korean government was actually in great need of escaping from international isolation. In this trend, the KCF tried to become a member of WCC twice in 1974 and 1981, published Old and New Testaments and hymnals, and allowed overseas Koreans to visit North Korea. After all, North and South Korean church delegates met in 1986 in Glion, Switzerland, through the mediation of WCC, for the first time ever since the division of Korea. The member churches of National Council of Churches in Korea(NCCK) led reunification movement of South Korean churches since the late 1960s. They were actively involved in human rights and democratization movement through which ecumenical solidarity with churches around the world was created. As the time is ripe for it, delegations from NCCK and churches around the world gathered together, through the mediation of WCC, in 1984 in Tozanso, Japan, to prepare for an ecumenical process("Tozanso process") for peace and reunification of the Korean peninsular. In 1985, a group of WCC delegation visited North Korea; in 1986, WCC sponsored the first North-South Korean Christian gathering in Glion, Switzerland, and three more gatherings until 1995. It is remarkable that since the 1990s, ecumenical and evangelical churches in South Korea began to cooperate each other as the latter also participates in the humanitarian aid for North Korean food crisis. Examining churches`` activities for reunification in North and South Korea, the author insists that North-South Korean Christian meetings have contributed greatly to dismantle the political taboo that has forbidden any exchanges between North and South Korea. The author, however, also argues that North Korean church is too weak to work independently as equal partner with South Korean churches, and thus that it needs to develop and strengthen its identify as a church living in socialist system. Finally, the author asks: Would "political reunification"be enough for future Korea? Institutional approaches like political reunification and socioeconomic integration, admits the author, are necessary; still,what is the moral and spiritual foundation of such institutional reunion of the two Koreas? Here, the author brings the concept of peace to the fore. Reunification of Korea, admits the author, must be realized by peaceful means; yet, the author stresses that peace itself must be the goal and aim of reunification. Political reunification, in other words, must be based on "gospel of peace."To conclude, the author reintroduces the concept of peace from a theological perspective, and raises the following ethical questions that should be considered in the process of the reunification of Korea:(1) The limit of real politics which is governed by "balance of power"(2) the atheisticfaith in national security;(3) prioritization of humanitarianism and the tasks of humanization; and(4) the interrelationship between(socio-psychological) fear and peace.

Step-advancement island flap을 이용한 수지첨부 손상의 재건
박명철 大韓成形外科學會 1990 Archives of Plastic Surgery Vol.17 No.3
Among the increasing hand injuries, finger-tip is being most frequently involved. Finger-tip is a primary contact area to external environment. The special sensory receptor sites in the glaborous skin are uniquely adapted for digital proprioception and should be preserved whenever possible. With a thoughtful consideration concerning etiology of the injuries, patients'age, occupation, and type of injuries, surgeon should select the method on an individual basis. An island flap based on single neurovascular bundle was used for finger-tip reconstruction. The design for step-advancement island flap incoperated the step ladder principle which ensures the provision of ample skin with full tactile sensibility in the required postion without the risk of longitudinal volar scar and with good nail support. Author reports 15 cases of fingertip injury repaired with step-advancemsnt island flap.
