Construction Management(CM) and Building Information Management(BIM) have a lot in common that they need to establish a cooperation system among different disciplines and promote smooth communication among project stakeholders throughout the project life-cycle. BIM can be an effective information management tool for CM's business and improve their service value. However, BIM uses by Construction Managers(CMr) are very limited. The objective of this study is to analyze the intention of CMrs to adopt BIM and establish effective BIM use strategy in the CMr's point of view. This study utilizes Technology Acceptance Model(TAM) as a research method, and the results show that 1) CMrs think it is more important whether BIM is required to be adopted in their business process at the social or industry level than that BIM can improve their personal competence, recognition, and impressions through their voluntary BIM adoption; 2) that CMrs think it is important to figure out business processes where BIM can be smoothly incorporated; and 3) that CMrs hesitate the use and trial of BIM in their realworld business although they agree that BIM needs to be eventually adopted in their business in the future. Based on these results, directions for establish a strategy for BIM adoption were proposed at the CMr's point of view

Purpose: In Korea, buildings make up 20.5% (2012) of the gross national energy consumption, so they are a major target for greenhouse gas reduction. In particular, energy consumption in multihousing represents approximately 32.6% of the entire building sector. With improving energy performance being the focus, efforts are continuously being made to reinforce standards and systems in greenhouse gas reduction. This study investigated the current status of multihousing in Korea in terms of energy performance as described in the performance evaluation reports submitted (to an institution that specializes in reviewing the performance evaluation of green homes) based on the construction criteria and performance codes for green homes and examined if the evaluation criteria using related methodologies were appropriate. The results will provide helpful information for reviewing the future directions of operations and amendments to the systems. Method: The overall characteristics of the system were examined using the evaluation methodologies (and current state of revisions) of the performance codes for green homes and comparing them with similar systems. Also, the current state of application and energy performance (conducted according to the evaluation methodologies) were compared by the evaluation institution for multihousing neighborhoods that were assessed for five years from 2010 to 2014. Result: It has been confirmed that the performance codes for green homes are different from other similar systems in evaluating performances of multihousing in that they allow both quantitative and qualitative methods of evaluation, and they consider both energy and sustainability simultaneously in the evaluation. Furthermore, regarding the adoption rate of the forms for the two evaluation methods (Form 1 - quantitative and Form 2 - qualitative), the rate preferring Form 2 increased gradually in time to reach 55.3% in 2014. In analyzing the rate of overall energy reduction (submitted in Form 1) and the coefficient of thermal transmission for each part (submitted in Form 2), it was observed that the deviation between the performance submitted and the criteria decreased in line with the level of reinforcement.

This study was conducted to investigate the effects of adjacent stand on the invasion of Robinia pseudoacacia plantations. The results were as follows. 1) Robinia pseudoacacia tended to invade into all directions regardless of the kinds of adjacent stands. But it was estimated that the invasion of Robinia pseudoacacia into adjacent stands could be very difficult, if the layer structure of adjacent stands were well developed. Whereas, it was estimated that Robinia pseudoacacia more rapidly intruded into adjacent stands, if adjacent stands were opened and bared. 2) Robinia pseudoacacia tended to invade into all aspects regardless of the kinds of vegetation units in the adjacent stands. But the dominance class of Robinia pseudoacacia in the adjacent stands showed a little differences among the vegetation units. The dominance class of Robinia pseudoacacia in Quercus aliena community and Quercus serrata community showed low level as + ~2, while the dominance class of Pinus densiflora community, Pinus rigida community, Quercus variabilis community and Quercus acutissima community represented high level as 1~4. Also the dominance class of Isodon inflexus subgroup among three subgroups of Pinus densiflora community showed the lowest level as + ~2.

A study has been carried out that effectively controls the vibration of asymmetric cable-stayed bridges caused by earthquakes with MR dampers. In order to enhance the practical serviceability of MR dampers, an asymmetric cable-stayed bridge structure has been designed and produced, and a MR damper has been produced so as to have this bridge structure controlled appropriately. An experiment that controls vertical and horizontal vibrations has been carried out by exciting the asymmetric cable-stayed bridge in the horizontal direction with the El-centro seismic wave. The control performance of the MR damper has been evaluated under the five control conditions in the experiments of vibration control in each direction. As a result of the experiment, MR dampers were proved to control vibrations more effectively when either Lyapunov control algorithm or Clipped-optimal control algorithm was used to control vibrations of the asymmetric cable-stayed bridge caused by earthquakes. In addition, different controlling effects were found in vibration controls in vertical and horizontal directions due to the asymmetry of the structure and the horizontal excitation. With such controlling effects, semi-active MR dampers are evaluated to effectively control vibrations caused by earthquakes in flexible and asymmetric structures such as asymmetric cable-stayed bridges.

This study proposed an estimation method of allowable wave height for loading and unloading of the ship considering ship motion that is affected by ship sizes, mooring conditions, wave periods and directions. The method was examined validity by comparison with wave field data at pier $8^{th}$ in Pohang new harbor. The wave field data obtained with wave height of 0.10~0.75m and wave period of 7~13s in ship sizes of 800~35,000ton when a downtimes have occurred. On the other hand, the results of allowable wave height for loading and unloading of the ship in this method have obtained with wave heights of 0.19~0.50m and wave periods of 8~12s for ship sizes of 5,000, 10,000 and 30,000ton. Thus this method well reproduced the field data respond to various a ship sizes and wave periods. And the results of this method tended to decrease in 16~62% when have considered long wave, and it is decreased in 0~46% when didn't consider long wave than design standards in case of the ship sizes of 5,000~30,000ton, wave period of 12s and wave angle of $75^{\circ}C$. The allowable wave heights for loading and unloading of the ship proposed by design standards are didn't respond to various the ship sizes and wave periods, and we have found that the design standards has overestimated on smaller than 10,000ton.

Current mobile content's classifications have two major problems. One violates a principle of classification and the other reveals limitations in dealing with various convergence services. This study proposes a new mobile content's classification system to resolve these problems by adapting Al Ries's principle of symmetric and asymmetric transition. Symmetric mobile contents take a form of mutation in convergence process; therefore, the contents would appear different from their originals whereas asymmetric type combines mobile contents in an autonomous way. This new system not only demonstrates a clearer classification but also implies the trend of mobile content development and services. The current suggests that symmetric type is preferable and symmetric type of mobile contents is re-developed to become a symmetric type as much as the technology can support. Nonetheless, it is found that asymmetric type would still be serviced to some extent. Thus, new mobile content's classification, proposed in this research, provides a more constructive understating of mobile content's directions in the era of digital convergence and a ground for comparative analysis of mobile content's development or positioning strategies.

This research was conducted to evaluate tile effects of polluted Suyeong River water on the water quality of Kwangan-Ri bathing beach. The quantity of pollutant loading of Suyeong River was determined in January 1979, and the directions of tidal currents and the chemical constituents of the Suyeong Bay water were observed in May 1979. The results are as follows: The quantity of total pollutant loading which was discharged into Suyeong Bay is: BOD 75.2ton/day; COD 96.9ton/day; SS 20.5ton/day; ammonia-nitrogen 12.4ton/day; nitrate-nitrogen 430kg/day; nitrite-nitrogen 85.1kg/day; phosphate-phosphorus 594kg/day and total heavy metals 3.01ton/day. Considering the tidal current, the polluted waters of Suyeong River flow off the Kwangan-Ri beach during tile ebb tides, and flow into the Kwangan Ri beach during the flood tides. Consequently, the water quality of Kangan-Ri bathing beach is not suitable for bathing.

Internationally, many countries are facing the demand for reshaping health care systems to cope with rapid changing circumstances in health care sector. The recent growth of oriental medicine and complementary and alternative medicine (CAM) in the many countries is, to a large extent, due to the growth of the number of oriental medical doctors and physicians who have taken up alternative therapies alongside conventional medicine. To cope with the changing environments, many countries consider to develop integrative health care which is now used widely in health care sector. In both biomedical and CAM sectors(including oriental medicine), attention appears to have shifted away from separating therapeutic modalities into categories such as biomedical or CAM, towards a focus on merging diverse modalities into a 'new' integrative health system. In Korea, one of peculiar characteristics of health care system is that as health care provider, Hanbang medicine (traditional Korean medicine) and (western) medicine coexist since 19 century. Recently, the government of Korea has given many efforts to enhance the role and function of traditional Korean medicine in health care sector. However, the strategies and measures for integrative health care settings combining traditional Korean medicine and western medicine on health sector have not been developed yet. The research question of this study is In Korea, what are the trends and problems in interface of traditional Korean medical sector and Western medical sector; what are the causes of or associated factors to the problems; how to cope with the problems and how to resolve the causes?; what are the health policy directions and its strategies that the government should take to cope with the future demand and the burden on health care sector? In order to do this, this study explores the current situations and issues on the interface between traditional Korean medicine and (western) medicine in various ways using contents analysis of existing data and documents related to traditional Korean medicine and health policy. Finally, we discussed stakeholders' views on the interface in the health care sector. Then, health policy options to have shifted away from separating therapeutic modalities into categories such as 'traditional Korean medicine' or 'western medicine', towards a focus on merging diverse modalities into a 'new' integrative health system.
