본 연구는 조선기자재 수출입 기업체를 대상으로 설문조사를 실시하여 수출입 물류에 관한 일반사항과 물류실태, 화물정보 제공, 화물 식별 및 분류, 화물 오배송 및 손상 등의 화물관리 상의 애로요인과 개선방안을 조사, 분석하여 조선기자재 수출입 물류에 있어서 화물관리의 문제점과 해결방안을 제시하였다. 조선기자재 수출입 물류가 원할히 이루어지기 위해서는 수출입 업체와 물류관련 업체 간의 화물상태와 위치에 관한 정보가 실시간으로 제공되어야 할 것이다. 그리고 수출입 화물의 지연과 소실 및 오배송을 줄이고 물류효율성을 제고하기 위해서는 표준 화물 분류시스템과 인식시스템의 제정이 시급히 이루어져야 할 것이다. 또한 조선기자재 전문 포워더의 육성과 전문성 강화가 필요하며, 이를 위해 포워더 담당자들에 대한 역량배양 교육을 수출입 업체와 물류업체가 공동으로 참여하여 조선기자재 제품 특성과 물류 특성을 모두 반영하여 수행하여야 할 것이다 This study investigates cargo management issues in the shipbuilding and marine equipment industry. Problems are analyzed concerning the absence of information about exact cargo location and condition, damage, loss, replacement, and transportation delays during the import and export process. Then, improvements are proposed to solve these problems. To illustrate, real time information about the status and location of cargo should be communicated between import/export and logistics companies to facilitate material logistics for shipbuilding & marine equipment. In addition, a standard cargo classification and recognition system should be established to reduce delivery delays and mistakes, so then enhancing logistical efficiency. Moreover, it is also necessary to nurture professional shipbuilding & marine equipment forwarders to strengthen their expertise with professional education and training.

우리나라 해양모델의시추설비 통합시운전 사업 개발 및 경제성 분석에 관한 연구

이창우,천영욱,신상훈,신용존 해양환경안전학회 2019 해양환경안전학회지 Vol.25 No.1

우리나라의 조선해양플랜트 산업은 2011~2015년 기간에 우리나라 품목별 수출기여도에서 1~4위를 차지할 정도로 대한민국 경제성장을 견인하는 중요한 산업이다. 이 연구는 과거 건조에만 치중했던 우리나라 해양플랜트 시추설비의 산업구조에서 통합시운전의 서비스 공급이 가능한 비즈니스 모델을 검토함으로써 시추설비 시장에서 우리나라 조선소의 국가경쟁력을 향상시킬 수 있는 방안을 제안 하고자 하였다. 2014년에 시도된 주작-1 폐공을 활용한 시운전 서비스 모델과 이의 한계 사항을 극복하고 사업을 활성화하기 위한 새로운 제안 비즈니스모델인 수심 150미터급 시운전 전용 모델의 경제성을 검토하였다. 경제성 평가 결과, 수심 150미터급 모델이 경제적으로 더 효과적인 것으로 나타났다. 그리고 통합시추설비의 시운전이 연간 2회에서 3,4,5회로 늘어남에 따라 NPV와 IRR 및 B/C 비율이 모두 증가 하였으며, 1회당 사용료는 감소하는 것으로 나타났다. 따라서 해양시추설비의 통합시운전 사업은 우리나라에서 건조되어 인도되는 설비를 대상으로 시추 시운전을 적극적으로 유치하는 노력이 필요하다. The shipbuilding and offshore plant industry of Korea is important and leads Korea's economic growth, designated as the 1st to 4th export items in Korea in terms of export contribution over the period from 2011 to 2015. This study proposes ways to improve the national competitiveness of Korean shipyards in the global offshore drilling market by reviewing a business model for providing an integrated offshore drilling commissioning service in Korea. This commissioning service model, which was attempted in 2014, was reviewed, and a new proposed business model for overcoming the limitations of the previous model and activating further business was evaluated. As a result of an economic evaluation, it was found that a 150-meter water depth model is economically more effective. As the number of integrated commissions increased from 2 to 5 times per year, NPV, IRR and B/C ratios increased and the fee per use decreased. Therefore, for offshore drilling facilities constructed and delivered in Korea, it will be necessary to encourage integrated offshore commissioning.

차종희,정미숙,천영욱 조선대학교 1995 The Medical Journal of Chosun University Vol.20 No.1

In order to investigate effects of selenium on paraquat-induced toxicities. we measured the enzymes involved in the glutathione metabolism, which Includes glutathione s-transferase, r-glutamylcysteine syntheatse and r-glutamyltranspeptidase, and the contents of glutathione in the paraquat-treated and paraquat plus seleniun-treated groups, respectively. 1. The survival rate was great)y diminished in paraquat plus selenium-treated group compared with paraquat-treated group. 2. The content of 81utathione in paraquat plus selenium-treated group was also reduced to 17.5% and 31.7% in liver and kidney, respectively as compared to the corresponding control values. 3 The activity of r-glutamylcysteine synthetase in paraquat-plus selenium group was significantly increased in liver but not affected in the kidney. 4. The activities of glutathione s-transferase in liver and kidney were not affected in both groups. 5. The activity of r-glutamyl transpeptidase in kidney in was increased to 54% in the paraquat plus selenium groups as compared to that of the control group. These results taken together suggest that the coadministration of selenium and paraqua enhances paraquat-induced toxicities, which appear to be associated with the decreased level of glutathione in liver and kidney.

Malignant histiocytosis, originally described in 1939 as histiocytic medullary reticulosis by Scott and Robb-Smith, is a rare histiocytic proliferative disorder that often shows an acute onset and used to progress to death within a few months. This disorder characterized clinically by fever, generalized weakness, lymphadenopathy and hepatosplenomegaly, and shows a variable range of pancytopenia. Extranodal involvement is common, with an incidence ranging from 50% to as high as 90%, skin involves8ment was noted in 10% to 15%. Typical skin lesions were mainly founded in extremity. i.e. erythematous papule and nodule occasionally become to necrosis and ulceration. We experienced one case of malignant histiocytosis in a 46-years-old female. The major clinical findings are fever, malaise, hepatosplenomegaly and erythematous skin lesion. In the laboratory study, pancytopenia is noted on the peripheral blood. And also aggregation of many atypical histiocytes were shown on skin and bone marrow biopsy. So we reported one related case with malignant histiocytosis as well as reviewing literature .

김명철,박재윤,채기영,천영욱,박평심,차종희 朝鮮大學校 附設 醫學硏究所 1991 The Medical Journal of Chosun University Vol.16 No.2

The participation of superoxide in initiating tissue damage from administration of a xenobiotics is best illustrated by paraquat intoxication, in which it is known that one electron reduction of paraquat leads to the formation of radicals which react with molecular oxygen to give superoxide. In the present study, the effects of paraquat on the level of glutathione and activities of superoxide dismutase(SOD), catalase, glutathione peroxidase, glutathione reductase and glutathione stransferase were investigated in rat liver and erythrocytes. The contents of glutathione in liver and blood were sinificantly decreased by paraquat administration, but the activities of enzymes were unaltered. Incubation of the buffered aerobic mixture of erythrocyte in the presence of 5mM glucose, Paraquat and/or N-ethylmaleimide(NEM) resulted in the formation of lipid peroxide, the activities of various enzyme and the levels of glutathione were determined. The malondialdehyde(MDA) contents as a indicator of lipid peroxidation was decreased and the levels of total glutathione were not changed but the levels of oxidized glutathione(GSSG) were in creased in paraquat treated erythrocytes. The activites of ezyme were decreased in paraquat treated erythrocytes but in reduced glutathione(GSH) treated erythrocyte, the enzymes activities were less decreased by paraquat. These results suggest that paraquat toxicity was probably somewhat reduced by GSH, but paraquat-induced injury were not increased by GSH depletion in erythrocytes.

Multiple myeloma is a disease caused by neoplastic plasma cells that synthesize abnormal amouts of immunoglobulin or immunoglobulin fragments. Light chain myeloma are regarded as a separate category characterized by a more malignant clinical course. Light chain myelomas are said to grow fastest of all and are associated with more osteolytic lesions, more hypercalcemia, and a higher incidence of renal failure and amyloidsis than either the IgG, IgA varienties The authors experienced a case of patients with λ-light chain myeloma. A 43-year-old male patient admitted to our hospital with the chief complaint of both rib and lower back pain. The radiologic findings showed multiple pathologic fracture in ribs. osteolytic lesions in 2nd, 3rd cervical spineimmuture plasma cells. Serum electrophoresis showed normal finding. Urine electrophoresis evealed an M-spike. Urine immunoelectrophoress demonstrated λ-monoclonal protein. With the cycle of melphalan, prednisone and α-interferon chemotherapy improved of pain was observed. So we reported the case with brief review of previous literature.
