1970년대 대한조선공사의 옥포조선소 건설과정 : 중화학공업화 정책 하의 국가와 기업

배석만(Bae-Suk Man) 한국경영사학회 2021 經營史學 Vol.99 No.-

본 연구는 박정희정권의 중화학공업화 선언을 계기로 시작된 대한조선공사의 옥포조선소 건설과정을 구체적으로 분석하였다. 이를 통해 몇 가지 새로운 사실을 밝혔다. 첫째, 수출용 대형유조선을 건조하는 전문조선소로 출발한 옥포조선소는 불황으로 다목적 조선소로 건설 방향을 바꾸었다. 이 과정은 대형유조선 전문 조선소 유지하려는 기업과 정부부담을 줄이려는 타협의 산물이었다. 둘째, 공사 중지를 포함한 전면적 구조조정 문제는1978년 대우조선으로 사업주체가 교체되는 시기가 아니라 1977년 본격적으로 검토되었다. 태스크 포스 회의가 열리고, 관련 실무 작업반까지 조직한 전면적인 재검토 작업이이루어졌다. 셋째, 구조조정 검토의 결론은 대한조선공사가 건설공사를 계속하는 것이었는데, 사실 잘못된 판단에 근거한 것이었다. 세계 조선시장이 1980년 이후 회복될 것이며, 그 근거로 중소형 선박 시장의 확대, 이중벽 유조선 수요를 들었으나, 주지하듯이1980년대에도 세계 조선산업은 불황이 지속되었다. 이중벽 유조선 수요도 1990년대에들어서 점차 확대되었다. 재무부와 한국산업은행이 정확히 예측하여 공사 중지에 무게를실었으나 관철되지 못했다. 넷째, 1978년 사업 주체 교체는 정부 의도 보다는 대한조선공사의 공사 포기에 따른 어쩔 수 없는 조치였다. 정부는 재벌그룹 현대, 대우와 교섭했으나, 현대에게는 사실상 거절당했고 대우에게는 대가로 특혜를 줄 수밖에 없었다. 다섯째, 옥포조선소 건설 사례로 볼 때, 1970년대 박정희정권의 중화학공업화정책 추진과정은 국가의 ‘계획의 합리성’만으로 설명할 수 없다. 정부는 내부적으로 통일되지 않았으며, 일관성이 없기도 하였고, 잘못된 판단에 의거하여 정책이 추진되기도 하였다. 당연한 얘기일 수도 있으나 기업 역시 일방적으로 정책에 끌려갔던 것이 아니었다. 오히려 정부 정책을 조정․조율하는 중요한 한 축을 담당하였고, 생각보다 큰 영향을 미쳤다. This study analyzed in detail the construction process of the Okpo Shipyard of Korea Shipbuilding Corporation, which began with the declaration of heavy and chemical industrialization under the Park Chung-hee regime. This revealed some new facts. First, Okpo Shipyard, which started as a shipyard specializing in building large oil tankers for export, changed its construction direction to a multi-purpose shipyard due to the recession. This process was the product of a compromise to reduce the burden on the government and companies that wanted to maintain a shipyard specializing in large tankers. Second, the issue of total restructuring, including the suspension of construction, was seriously considered in 1977, not when the business entity was replaced by Daewoo Shipbuilding in 1978. A task force meeting was held, and a full-scale review work was carried out, including the relevant working group. Third, the conclusion of the restructuring review was that Korea Shipbuilding Corporation would continue the construction work, but in fact, it was based on an erroneous judgment. The global shipbuilding market will recover after 1980, and the expansion of the small and medium-sized ship market and the demand for double-wall tankers were cited as the grounds. The demand for double-wall tankers also gradually expanded in the 1990s. The Ministry of Finance and the Korea Development Bank accurately predicted and put weight on the suspension of the construction, but it was not implemented. Fourth, the change of project subject in 1978 was an unavoidable measure following the abandonment of construction by Korea Shipbuilding Corporation rather than the government’s intention. The government negotiated with the chaebol groups Hyundai and Daewoo, but was virtually rejected by Hyundai and had no choice but to give Daewoo preferential treatment in return. Fifth, in the case of the construction of the Okpo Shipyard, the process of promoting the heavy and chemical industrialization policy of the Park Chung-hee administration in the 1970s cannot be explained only by the national ‘rationality of the plan’. The government was not unified internally, was inconsistent, and policies were promoted based on wrong judgments. It may be obvious, but companies were not unilaterally drawn to policies. Rather, it played an important role in coordinating and coordinating government policies, and had a greater impact than expected.

재조일본인기업가 이케다 스케타다(池田佐忠)의 戰後 재기노력과 좌절

배석만(Bae, Suk-Man) 부산대학교 한국민족문화연구소 2015 한국민족문화 Vol.56 No.-

본 연구는 일제시기 부산을 거점으로 기업 활동을 전개한 재조일본인기업가 이케다 스케타다(池田佐忠)가 일제 패망 후 모국으로 돌아가 재기를 위해 전개한 다양한 사업의 추진과정과 그 귀결을 분석하였다. 이케다는 일제 패전 직후 일본에서의 사업전개를 위해 신속하게 움직이고 있었고, 1952년 7월 심장병으로 갑자기 사망할 때까지 다양한 영역에서 정력적인 기업 활동을 전개했다. 그 내용은 귀환 후 최초 사업인 염전사업부터, 주택건설사업, 멕시코 석유개발사업으로 이어졌다. 사업은 일제시기 부산에서의 기업 활동을 토대로 했고, 연장선상에 있었다. ‘사업보국’의 신념으로 무장하고, 끊임없는 관련 관청, 중앙 정부와의 접촉을 통해 지원과 특혜를 이끌어내려고 시도하는 사업방식 역시 변함이 없었다. 그러나 그의 재기를 위한 사업전개는 순조롭지 못했다. 일제시기 조선축항이 유야만에 투자한 기반을 토대로 시작한 제염사업의 경우 낮은 생산성과 戰後 혼란기의 기자재 공급지연 등으로 기대한 성과를 내지 못했다. 울산건설이 소유한 거액의 국채를 토대로 시도한 주택건설사업 역시 폐쇄기관 동척의 지분을 출자로 전환시키는데 실패함으로써 좌절되었다. 이케다가 ‘석유보국’의 기치를 내걸고 ‘최후의 천직’으로 삼았던 멕시코 석유개발사업 역시 자금 조달 문제가 해결되지 않은 상황에서 개발대상 석유광구가 소송에 휘말리는 등의 우여곡절과 이케다 자신의 사망으로 계획단계에서 좌절되었다. 이케다는 패전 후 일본에서 일제시기와 마찬가지로 변함없이 조국에 충성하고 헌신했지만, 그의 위상은 경계인이자 주변인의 위치에서 벗어나지 못했다. 특히 식민지 기업 활동의 유산인 울산건설을 토대로 추진한 주택건설사업에서 잘 보여주듯이, 미국에 의해 ‘민주 국가’로 탈바꿈하고 있던 戰後 일본에서 그는 ‘제국 일본의 유산’으로서 청산의 대상이었다. 결국 이케다의 재기를 위한 사업 활동의 전개과정과 그 귀결은 식민지 재조일본인의 국가에 대한 충성도에 상관없는 태생적인 경계인, 주변인 성격과 그 한계를 보다 두드러지게 보여주는 것이었다고 하겠다. 戰前과 전후, 그의 사업보국의 경영이념과 국가에 기댄 기업 활동방식에 변함이 없었듯이, 그 결과로써의 경계인, 주변인의 역사적 위상도 변함이 없었다. This study analyzed the process of promotion and consequences of various businesses developed by Japanese entrepreneur residing in Joseon, Suketada Ikeda, who developed business activities in Busan as a foothold during the Japanese colonial period, after returning to his home country after Japan’s defeat. Ikeda moved fast for the development of business in Japan immediately after the defeat of Japan and energetically developed business activities in various areas till he suddenly died of heart disease in July 1952. His activities led from salt pond business, the first business after his return through housing construction business to oil development project in Mexico. The business was built on his previous business activities in Busan during the Japanese colonial period, which was an extension. His belief, ‘patriotism through business’ and his business approach in which he was trying to bring about support and preferential treatment through incessant contacts with related authorities and the central government remained unchanged. However, his business progress for recovery was not smooth. His salt manufacture business started based on the investment in the Gulf of Yuya by Joseon Harbor Construction Co., Ltd. during the Japanese colonial period did not produce expected performance due to low productivity and delay in equipment supply during the postwar period of chaos. His housing construction business attempted based on the large amount of government bonds owned by Ulsan Construction Co., Ltd., too, was frustrated by the failure of conversion of the shares of a closed institution, Oriental Development Company into investment. Mexico oil development project Ikeda took as his ‘final vocation’ putting up the banner of ‘patriotism by petroleum,’ too, was discouraged at the stage of planning due to a complication that the oil mining area, the target of development faced a lawsuit in a situation in which the problem of capital financing was not settled and his own death. Ikeda stayed loyal and devoted to his country after the defeat as he did during the Japanese colonial period, but his status did not go beyond that of a peripheral subject and marginal man. Especially, as well shown in his housing construction business promoted based on Ulsan Construction Company, a legacy of the colonial enterprise activity, in post-war Japan that was transforming itself to a ‘democratic country’ by the U.S., he was an object of liquidation as ‘a legacy of imperial Japan.’ Consequently, the process of development and consequences of Ikeda’s business activities for recovery showed his inherent nature and limitation as a peripheral subject and marginal man, irrespective of the allegiance of the Japanese people residing in Joseon to the country more noticeably. Before and after the war, like his management philosophy of patriotism through business and way of enterprise activity depending on the state remained the same, his historical status as a peripheral subject and marginal man as a result remained unchanged.

일제시기 日本硬質陶器株式會社의 기업경영 분석

This study analyzed the process of developing the management of Japan Ironstone Chinaware Mfg. Co. Ltd (Japan Ironstone Chinaware) that set up factories both in Kanazawa and Busan and developed production of industrial pottery and porcelain. Japan Ironstone Chinaware was established as a regional corporation in Kanazawa in 1908, and then took advantage of the warboom of World War Ⅰ and entered into Korea in 1917. This was intended to mass-produce the pottery and porcelain for export through the use of the raw materials and cheap labor in Korea under Japanese colonial rule. However, it faced difficulties in the management during long-term economic recession in the 1920s. In 1925, Japan Ironstone Chinaware accepted Gentaro Kashii, who was a leading capitalist in Busan, as president in order to restore the management, and attempted reforms such as moving its head office to Busan to receive support from the Chosen Government-General. However, it was not enough to overcome the long-term economic depression. Japan Ironstone Chinaware came out of the financial difficulties and then got on the right track of restoring the management since the mid-1930s. It was thanks to recovered energy of the export market that had not been able to come out of the economic depression during that time. Also, this established the ‘division of the production system of Kanazawa Factory ― high-quality product and Busan Factory ― low-quality product.’ The management in good times continued even in the wartime. This is because European countries were first involved in the war and Japan Ironstone Chinaware could hold a dominant position in the export market in Southeast Asia in competition with the European countries as the main market. However, entering the Pacific War period, Japan Ironstone Chinaware faced the management crisis again due to the closure of export markets. Japan Ironstone Chinaware attempted to overcome this crisis by developing the national project based on the Busan Factory. An attempt of establishing the mass production system of Chosen Tableware that took advantage of the compulsory delivery of metal by the Chosen Government-General was one of the typical business. Although Japan Ironstone Chinaware’s attempt achieved certain results such as an increase in the sales, it had limitations to pull out of the structural deficit and improve the management.

FMSS를 이용한 자율운항선박 충돌회피능력 정량화 평가 기법에 관한 연구

배석한(Seok-Han Bae),정민(Min Jung),장은규(Eun-Kyu Jang) 한국항해항만학회 2020 한국항해항만학회지 Vol.44 No.6

최근 자율운항선박(Maritime Autonomous Surface Ship, MASS) 기술개발에 관련 연구들이 활발하게 수행되고 있다. MASS의 핵심 기술 중 하나는 해상에서 항해사를 대신하여 조우하는 선박에 대한 충돌회피기술이다. 기존 자동 충돌회피기술 개발관련 연구들을 조사한 결과, 자동충돌회피기술을 객관적으로 정량화 할 수 있는 평가모델에 대한 연구는 없다. 따라서 본 연구에서는 MASS의 충돌회피 능력을 객관적으로 검증하기 위한 평가모델을 개발하였다. 연구방법은 COLREGs에 대한 전문지식과 실무조선 경험이 많은 선박조종전문가가 Full Mission Ship-handling Simulator(FMSS)를 이용하여 선박 조우형태별 선박조종시뮬레이션을 수행하고 그 결과 데이터를 계측하고 기술 통계 처리하여 것이며, 개발된 평가모델을 통해서, MASS의 운항능력을 정량적으로 평가하고자 하였다. 연구결과, 본 연구에서 개발된 충돌회피 평가모델을 이용하여 해상에서 MASS의 충돌회피 능력을 정량 평가 할 수 있는 것으로 나타났다. 향후 이 모델을 이용하면 자율운항선박의 충돌회피능력을 객관적으로 평가 가능하고 부족한 부분을 수정· 보완하는데 이용함으로서 자율운항선박 기술개발에 많은 도움이 될 것으로 사료되며, 또한 항해사의 충돌회피능력 평가에도 도움이 될 것으로 판단된다. Research related to the technology developed for the Maritime Autonomous Surface Ship (MASS) is currently underway. Although one of those core technologies is collision-avoidance technology for ship operators at sea, no research has been done to objectively quantify its effectiveness. Therefore, this study was conducted to develop an evaluation model to examine the collision-avoidance ability of MASS. Ship-control experts performed a ship-handling simulation for each ship encounter type using the Full Mission Ship-handling Simulator (FMSS). We used the resulting data and technical statistics, to develop an evaluation model that utilized FMSS to quantify the operational capability of the collision-avoidance technology. This evaluation model also can be used at sea to assess deck officers ability to use the technology and to improve and develop other MASS technologies.

Efficient thermal management system of electric vehicle is a crucial issue in views of energy consumption and balance in that its electric cabin heater reduces the charging range by 20 to 50 percent in the winter season. Carbon material is employed to develop a highly efficient cabin heater for electric vehicle, which is never been attempted at home and abroad. With its high thermal conductivity, carbon nanutube(CNT) heater can improve heat-up rate and reduce power consumption compared to conventional positive temperature constant(PTC). Carbon nanotube heater is superior in terms of reduced power consumption, stable heating, rapid heating rate to improve indoor comfort and winter defrosting function, weight reduction, durability and reliability. In this study, various carbon film heater patterns has been designed and tested in order to grasp the heat-up behaviors and search the optimal pattern design. Performance assessment of heating-up of carbon heating film has been carried out in comparison with conventional PTC stone for cabin heater. Carbon nanotube film presented prominent heat-up performance than the conventional heater element to a certain temperature criterion.

A construction equipment such as an excavator wastes about 90% energy out of the fuel. The annual fuel cost of an excavator is comparable to the price of the equipment. Application of a waste heat recovery system on an excavator is attractive and of high return by fuel saving considering the system cost and additional weight. A remarkable feature of the excavator is that the heat source for the waste heat recovery includes the hydraulic fluid in addition to the engine exhaust gas and the engine coolant. It is advantageous to choose a refrigerant in order to recover wast heat at relatively low temperatures. In this study, cycle analysis has been conducted to derive a schematic outline of the system layout and the performance specifications of the core parts of the waste heat recovery system for a 20-ton class excavator. From the cycle analysis, the adequate working fluid has been chosen from the refrigerant group. The cycle analysis has been performed via Refprop 8, which can calculate the properties at any temperature and pressure of refrigerants.
