The activity of phase II enzyme in the liver of mice was examined following the application of Cnidium officinale Makino aqua-acupuncture solution (COMAS). The application of COMAS $CV_{12}$ to mice for 7 days increased quinone reductase(QR) activity. The glutathione S-transferase(GST) activity was also increased with COMAS. A greater increase was observed in the glutathione(GSH) levels than in the QR and GST activities.

Recently, the construction companies are forced to cut down the investment amount due to increasing financial problems caused by severe recession and restructuring in the financial market as well as the long-term depression of the construction industry. To overcome this type of problems, a great many efforts have been made. An alternative may be adopting the advanced financing methods. However, during the course of enforcing process of the financing methods, many problems are revealed without any proper solutions being proposed. Therefore, the fundamental problems need to be solved through comprehensive and systematic approach under the changing environment of construction financing. In this paper, as a result of reviewing some financing methods such as ABS, REITS, and Project Financing, multiple business strategies for construction companies to cope with the changing construction market are found in the sense of effectiveness in implementing construction projects. Further, this paper presents diversified financing methods for the effective practice of construction projects through combination of above mentioned methods, and also proposes improvement plans to strengthen the financing function for the construction industry.

콘크리트 구조물 내구성에 대한 표면처리제 영향의 평가 모델 개발

한상훈 ( Han Sang-hun ),박우선 ( Park Woo-sun ) 한국구조물진단유지관리공학회 2007 한국구조물진단유지관리공학회 학술발표대회 논문집 Vol.11 No.2

A model estimating the influence of surface treatment on durability of concrete structure was proposed. The durability analysis adopting the surface treatment model showed that early and late diffusion coefficient and deterioration rate have much effect on the chloride ion penetration depth. Therefore, it can be concluded that the durability analysis on the basis of the model estimating characteristics of surface treatment is necessary for evaluating the applicability of surface treatment.

Recently mass concrete structures are being installed often and large amount of hydration heat proceeds due to lots of concrete casting on those works. Thermal crack may happen on structures by the proceeded hydration heat and this would cause damage to structures. Various ways to control thermal crack have been presented, but more realistic ways are required considering installation period and cost matter. Thus we would like to present a way of controlling thermal crack by changing curing temperature by means of analytical method. For this, we verified credibility of the program used comparing and analyzing the values gained from measuring hydration heat in the field, and estimated how curing temperature dose influence to hydration heat, thermal stress and thermal crack by increasing curing temperature and cubic volume of the structure. Consequently, the program used sharply estimated the maximum temperature, its proceeded time and rising & downward curve of hydration temperature, and it showed that we could control temperature crack of the mass concrete by changing curing temperature.

한상훈(Sang-Hun Han),최석범(Seok-Beom Choi) 중앙대학교 한국전자무역연구소 2012 전자무역연구 Vol.10 No.4

지난 수십 년 동안, 무역거래 참여자들, 국가들 그리고 국제기구 사이에서 전자무역에 대한 관심이 증폭되어 왔다. 전자무역은 무역절차의 속도를 향상시켜주고, 비용 절감을 가져다준다. 국제상업회의소에서도 이러한 전자무역의 영향을 인식하고 있었으며 Incoterms안에 전자무역에 대한 규정을 포함하여 왔다. Incoterms는 인도 의무, 매도인으로부터 매수인에게로 위험의 이전, 비용의 분배 그리고 운송서류에 대한 책임 등 여러 가지 요소를 명확하게 정의하고 있다. 본 논문은 국제상관습의 변화 중 특히 전자무역관습의 변화가 정형거래조건의 개정에 미치는 영향을 살펴보는 것을 목적으로 한다. For past decades, it had seen an explosion of interest in e-Trade between international trade participants, nations and international organization. E-Trade means that the process can be speeded up and that cost can be saved. ICC also was recognized about these impact of e-Trade and had included provisions of e-Trade in Incoterms. Incoterms allow several elements to be precisely defined the delivery obligations, the risk transfer from the seller to the buyer, the distribution of costs and the responsibility for the transportation documents. The purpose of this paper is to study the impact of revised trade terms, which are changed by international commercial practice, in particular, the changes of the e-Trade custom.

한상훈(Han, Sang-Hun),박우선(Park, Woo-Sun) 한국해안해양공학회 2008 한국해안해양공학회 논문집 Vol.20 No.6

콘크리트 구조물의 내구성 저하에 큰 영향을 미치는 요인 중의 하나로 인식되고 있는 탄산화가 항만 구조물에 미치는 영향을 현장실험결과를 바탕으로 정량적으로 평가하고자 하였다. 전국 65개 항만시설의 369개소의 탄산화 깊이 측정결과를 이용하여 강도와 탄산화 깊이의 상관관계 및 피복두께와 탄산화 깊이의 상관관계 등에 대해서 고찰하였다. 또한, 기존 탄산화 모델식들과 계측결과들을 비교하고 실험결과들을 바탕으로 신뢰성 이론을 기반으로한 탄산화에 의한 내구성 파괴확률(철근부식확률)을 검토하였다. 현장실험결과에 의하면 대부분의 탄산화 깊이가 피복두께의 0.2배 이하 수준이었다. 또한, 강도의 증가에 따라 탄산화 깊이가 감소하고 재령의 증가에 따라 탄산화 깊이가 증가함을 관찰하였다. 신뢰성이론을 기반으로 탄산화에 의한 내구성 파괴확률을 판단하였는데, 대부분의 경우에 부식확률이 10%미만으로 관찰되었다. 따라서, 탄산화 단일열화조건으로는 항만 콘크리트 구조물의 내구성 저하에 큰 영향을 주지 않을 것으로 판단하였다. Carbonation is one of major factors influencing on the durability of concrete structure. This paper investigates the effect of carbonation on the soundness of harbor concrete structure and quantifies the influence of carbonation based on in-situation data tested at 369 points in 69 harbor facilities. The relationships between carbonation depth and cover depth, and between carbonation depth and compressive strength are studied and the failure probability of durability, that is the initiation probability of steel corrosion, is evaluated on the basis of reliability concept. The in-situation test results showed that the ratio of carbonation depth to cover depth was less than 0.2, and the carbonation depth increased with age. In most cases, the failure probability of durability by carbonation was less than 10%. Therefore, it can be concluded that the influence of carbonation on the durability of harbor concrete structure is smaller than other factors deteriorating the durability of harbor concrete structure.

한상훈(Han, Sang-Hun),이진학(Yi, Jin-Hak),박우선(Park, Woo-Sun) 한국해안해양공학회 2011 한국해안해양공학회 논문집 Vol.23 No.1

항만콘크리트 구조물의 내구성 저하의 중요한 요인은 염소이온침투에 의한 철근의 부식이다. 따라서, 항만콘크리트 구조물의 염소이온 깊이와 깊이별 염소이온농도를 정량적으로 파악할 수 있다면, 구조물의 잔존수명을 사전에 비교적 정확하게 평가할 수 있다. 이러한, 구조물에서의 염소이온농도를 예측하기 위해서는 모델식의 개발이 필요하고 모델식은 정확한 현장데이타를 기반으로 한다. 이에 본 연구에서는 현장 항만구조물에 대한 코어시료를 채취하고 본 시료들에 대한 염소이온침투깊이와 깊이별 염소이온농도를 측정하고자 하였다. 시료는 1차로 완도항, 마산항, 인천항에서 채취하였고, 2차로 여수항과 동해항에서 채취하였다. 수직 높이별 영향을 파악하기 위해서 대기부, 비말대, 간만대로 나뉘어 각 층별 8개의 시료를 획득하였다. 채취된 시료중에서 4개는 강도 실험을 실시하였고, 나머지 4개로 내구성 실험을 실시하였다. 2개의 시료에 대해서는 질산은 변색법을 이용하여 염소이온 침투깊이를 측정 하였다. 나머지 2개의 시료는 깊이별로 5 mm 두께의 절편을 채취하고 이를 ASTM C 114의 시험법에 따라 염화물 이온농도를 측정하였다. 측정결과를 바탕으로 지역과 수직위치에 따른 염소이온 침투의 특성을 파악하였다. A major source of durability problems in concrete structures is the corrosion of steel by the damage of passivity layer around steel bars. As chloride ion penetration is major cause of the destruction of passivity layer, evaluation of depth and concentration profile of chloride ion is the essential factor for the service-life estimation of concrete structure. To estimate chloride ion penetration characteristics, this paper on the basis of in-situ experimental data investigated the depth and concentration profile of chloride ion penetration. The core specimens are obtained at air-zone, splash zone, and tidal zone in Wando, Masan, Incheon, Gwangyang, and donghae harbors. Colorimentric method measured the chloride ion penetration depth and ASTM C 114 evaluated the concentration profile of chloride ion. Based on experimental data, the influence of harbor location and exposure condition on chloride ion penetration is evaluated.

Since 1936, International Chamber of Commerce has published International Commercial Terms, also known as Incoterms, in order to facilitate global commerce. International commercial practice has been constantly changing to reflect alterations, such as the development of ship-building technology, the emergence of a container, the development of unloading technology, and the introduction of air transportation. Most recently revised Incoterms 2010 became effect from January 1, 2001 and it has reflected a lot of changes about transport custom. The purpose of this paper is to analyze the impact of revised trade terms which are changed by international commercial practice in particular the changes of the transportation custom. For this purpose, firstly this study analyzes the change of transport custom separately as marine transport, multimodal transport and air transport. Secondly, this study finds the amendments of each revised Incoterms version according changes of transport custom. Finally, this paper contributes to advise the parties concerned to understand the new changes of the trade terms under Incoterms 2010.
