The widespread of IT technology caused a remarkable change in many industries and the construction industry is also one of them being influenced in the form of CIC(Computer Integrated Construction) and BIM(Building Information Modeling). Construction projects have many participants from various disciplines involved throughout the entire process. Therefore the success of the project greatly depend on the efficiency of decision-making using the information generated from each process stage. Looking from this aspect, the greatest potential value lies in the planning and pre-design stage when considering the construction life cycle. In this paper, we propose a project on developing a 3D object oriented simulation system for supporting the pre design phase. We define the needs for such system through previous case studies and suggest a to be process model. Finally we anticipate the effects that the project will eventually contribute to the construction industry.

Cold storage warehouse industry in Japan has been extended in its scale in terms of both the number of storages and cold storage capacity in order to meet the extended reproduction of the marine products industry. However, increasing total amount of the stored goods since mid 80s led to relative decrease of marine products while the number of storages was remained the same or decreased, though cold storage capacity was gradually increased and is maintained the increase of the average cold storage capacity. As structural change in the cold storage warehouse industry emerges, cold storage warehouses require new approach to individual storage management with 1)diversity of the stored goods; 2) more competition due to increase of the cold storage capacity; and 3) sizing of the average cold storage capacity. Therefore, this study analyzed how cold storage warehouse management activity with individual storage sizing changes; and significance of sizing and functional change in cold storage warehouses experiencing sizing, by observing leading cold storage warehouse industry of the metropolitan area in Japan. In conclusion, reorganization of cold storage warehouse industry in the metropolitan area in Japan can be summarized as follows: First, competition among cold storage warehouses in the metropolitan area in Japan is not simply limited to storage industry but extended to establishment and securing physical distribution function. Second, since cold storage warehouse industry is in Scrap & Build phase, decision of management executives on whether taking direction to maintain/continue enhancement of physical distribution function may cause drastic reorganization in the cold storage warehouse industry, Third, since profit of physical distribution management based on cold storage warehouses is insignificant, it is not easy to accomplish expected management outcome, Fourth, today's cold storage warehouse industry mainly characterized by diversity of the stored goods needs facility reorganization with comprehensive and functional integration covering from F class cold storage capacity to F&C class.

우리나라 산업의 1990년과 2000년의 $CO_2$ 배출량을 각각 추정하고, 이 기간중 배출량 변화에 영향을 준 요인별 기여도를 조사하였다. 산업별 배출량에는 생산과정에서 직접 사용하는 에너지는 물론 원재료 생산에 사용된 에너지로 인해 간접적으로 배출되는 $CO_2$까지 포함하였다. 배출량 추정에는 통상적인 산업연관모형을 환경부문으로 확장한 $CO_2$ 혼합 산업연관모형을 이용하였다. 배출량 변화의 요인 분해에는 산업연관분석을 이용한 구조분해기법 (IO-SDA)을 사용하였다. 이 때 각 요인별 영향 계산에 적용하는 가중치는 기준연도와 비교연도의 평균값을 사용하여 가중치 선택의 자의성을 줄이고 완전분해가 되게 하였다. 추정 결과 국내 산업의 직 간접 $CO_2$ 배출량은 1990년에 6,444만 탄소톤에서 2000년에는 1억 1,552만 탄소톤으로 5,163만 탄소톤이 증가한 것으로 나타났다. 직접 $CO_2$ 유발계수 변화, 간접 $CO_2$ 유발계수 변화, 국내 최종수요 성장, 수출 증가, 수입 증가, 국내 최종수요 구조 변화, 수입 구조 변화, 수출 구조 변화 등 여덟 가지 요인별로 배출량 변화에 미친 영향을 분석한 결과 직접 $CO_2$ 유발계수 변화, 간접 $CO_2$ 유발계수 변화, 수입수요의 증가 및 구조 변화는 배출량 감소 효과를 낳았으나, 국내 최종수요 성장 및 구조 변화와 수출수요 증가와 구조 변화는 배출량을 증가시키는 요인으로 작용하였다. 산업이 직접 사용하는 에너지로 인한 $CO_2$ 배출량은 물론 제품 생산 과정에서 투입된 원재료의 생산에 소요된 에너지로 인한 배출량까지 모두 파악하는 것은 $CO_2$ 배출 저감 정책의 효율성을 높일 수 있는 기초자료로 활용될 수 있을 것으로 생각된다.

2000년~2011년 동안 제조업의 생산액 변화에 기여한 요인과 요인별 기여도를 투입산출 구조분해분석으로 한국과 일본 간에 비교하였다. 분석결과에 따르면, 제조업 생산 증가에 가장 크게 기여한 요인은 한국의 경우 수출인 반면에 일본에서는 기술변화이다. 한국 제조업 생산 증가에 대한 기술변화의 기여도는 상대적으로 미미하며 감소하고 있는 것으로 분석되었다. 한편, 국내최종수요는 한국에서는 수출에 이어 제조업 생산 증가의 두 번째 기여요인인 반면에 일본에서는 제조업 생산 감소의 가장 큰 기여요인이다. 특히, 두 국가 모두에서 중간재와 최종재의 국산화율은 감소하여 제조업 생산 위축의 주요 요인으로 작용하였다. 결과적으로 한국 제조업의 수출의존적 성장을 재확인하였으며, 이러한 수출의존도가 강화되고 있음도 확인하였다. 하지만, 과도한 수출의존도는 점점 심화되고 있는 세계경제 변동성과 불확실성을 고려할 때 한편으로는 한국 제조업의 지속적 성장에 장애요인이 될 수도 있음을 의미한다. 따라서 모든 기여요인이 균형적으로 성장에 기여하는 것이 중요하며, 특히, 상대적으로 저조한 것으로 분석된 기술변화의 기여도를 높이기 위한 연구개발 및 기술혁신 강화와 중간재 및 최종재의 국산화율 높이기 위한 노력이 더 요구되는 정책적 시사점이 있다.

The purpose of the present study is to establish structural noise analyzing method for apartments building floor with structural-acoustic coupling analysis modeling. Noise through floor in the room is recognized as a significant problem with the consequence that noise isolation technique has been studied in the various fields of industry. From among noise factors, resonance sound is the main reason for solid noise of the floor, which is occurred by mechanical vibrations of the acoustic boundary line and the change of velocity. To analyse this phenomenon, numerical computation methods are provided in many fields, In this study, evaluation method for slab is established using finite element method, and a case study for analyzing acoustic phenomenon was suggested. The results show that numerical method, especially F.E.M, has a good approximation to predict noise at floors.

The enactment of OPA90 (Oil Pollution Act of 1990) in the USA and the consequent moves by IMO(International Maritime Organization) to introduce new Regulations for the design of oil tankers led the oil transportation industry to undergo a period of big change. This resulted in the introduction of double hull tankers. This paper introduces the design for the 300, 000 DWT double hull VLCC of World-Wide Shipping Agency Pte Ltd. in Hong Kong, which is the first of this type constructed by Daewoo Shipbuilding & Heavy Machinery Ltd.(DSHM). The characteristics of the compartment and structural arrangement of this vessel are briefly described, and the scope of structural analysis is illustrated. In addition, the merits/demerits of different crosstie arrangements are described in the appendices.

The purpose of this study is to examine the organizational politics, resistance change, turnover intention, and organizational commitment of organizational members during mergers and acquisitions. Recently, many companies are interested in mergers and acquisitions for business diversification and market extension. A merger is a legal consolidation of two entities into one, whereas an acquisition occurs when one entity takes ownership of another entity's stock, equity interests, or assets. This research model establishes a structural equation model. This model is set in a causal relationship between manager's organizational politics, peer organizational politics, and change resistance and the change resistance has a causal relationship of turnover and tissue immersion. In particular, this study will test different of organizational politics by position. Research results, the organizational politics of managers and colleagues have shown increasing change resistance. The change resistance has resulted in a reduction of organizational commitment and an increase of turnover intention. Next, the position analysis showed that top management level, middle management level, and working-level officials showed different organizational politics. The working-level officials are influenced by their manager politics and are influenced in organizational commitment and turnover intention by change resistance. The middle manager level is influenced by the organizational politics of bosses and colleagues, and organizational commitment is weakened by change resistance. The CEO level is not affected by organizational politics in the company, but the turnover intention is strengthened and the organizational commitment is weakened by the change resistance. This study has contributed to further updating the theory of organizational politics based on mergers and acquisitions. As a practical implication, we suggest an organizational integration strategy for a new organization.
