Construction designs are often produced with insufficient considerations on the constructability aspects. Poor constructability has resulted in delay, cost increase, disputes, safety hazards and inconvenience to the public. Increasingly, there has been a call for more systematic input of construction knowledge in the planning and design processes of modern day's infrastructure development. In some countries, notably the US, the practice of constructability reviews is on the rise, with concomitant benefits. It is advocated that construction plans and designs be subject to constructability reviews as early as possible. It should be made part of the project management strategy driven by the client. This paper outlines the constructability review process and benefits, whilst drawing lessons from a number of case studies.

These days, the extension and complication of construction project has attached greater significance to IT system for effective project management. Construction companies inside the country have established IT system, but the fact is that they are not up to the expectations of investment provision, and the absense of objective and strategy about project management information system makes its efficiency doubtful. The research, from the point view of construction company, makes an estimate of indefinite future, and presents the process of making out IT system roadmap as a long-term strategy in building IT system.

Building Information Modeling (BIM) comes to be implemented into architectural design, construction, and maintenance in Japan in order to convert design information thoughout a construction project. However, various problems are taking place in data transaction. It is not also clear about the role and the responsibility of the architects and the enginners in charge.There is a movement to establish a BIM manager as a general coordinator concerning BIM in Singapore and other countries, though it is not yet popular in Japan. This paper deals a BIM manager as a new profession in a construction project. The function and skills necessary to a BIM manager is analyzed, and the strategy of Japanese general contractors is discussed. General contractors from Japan are operating BIM in Singapore compatible with open system of supply chain. This style is different from the one in Japan even they belong to the same company. In this paper it is analyzed based on the survey in detail.

Trust is emphasized as one of the most important factors in various e-commerce related studies. It is no exaggeration to say that in the area of e-commerce, trust-building with customers determines a company's success or failure. That is why most e-commerce based companies spare no time and effort in building trust with customers. Without exception, trust is one of the most critical factors influencing a customer's decision making process of whether to purchase Internet automobile insurance. This study attempts to provide useful guidelines for the sales-enhancing strategies of Internet automobile insurers, by delving into research questions concerning 1) gender differences in Internet automobile insurance customers' recognition of trust, and 2) gender differences in the effective trust factors influencing one's intention to purchase of Internet automobile insurance. The study finds that while the shape of trust-recognition toward three types of trust factors is very similar for both gender groups, the intensity of trust for each gender group in overall is pretty different. The results indicate that there exist gender differences in the trust factors influencing one’s intent to purchase Internet automobile insurance. The results of this study will provide useful guidelines for Internet automobile insurers in establishing effective and differentiated marketing strategies.

In this study, energy saving performance of outdoor temperature reset control strategy for central cooling system is researched by experiments. Outdoor temperature reset control is the control method to change indoor air set temperature according to outdoor air temperature change. The range of indoor air set temperature is represented by the comfort temperature range of indoor air temperature offered from ASHRAE and indoor air set temperature is programmed between $22^{\circ}C$ and $27^{\circ}C$ by outdoor air temperature $20^{\circ}C{\sim}32^{\circ}C$ in summer. As a result of applying outdoor temperature reset control to central cooling system, the suggested control method shows better performances of energy savings than the conventional method which indoor temperature maintains constantly.

Security situations are fundamentally and rapidly changing on the Korean Peninsula. Above all, as North Korea(NK) is heightening its nuclear and missile capabilities, Republic of Korea(ROK) is facing an existential threat. At the same time, as China's economic, diplomatic and military power is quickly rising, the balance of power is shifting and strategic competition between the Unite States(US) and China is accelerating in the Asia-Pacific region. Under the pressure of development of these situations, ROK seems to face allegedly the most serious crisis in its national security since the end of the Korean War. In the current grim geopolitical situation, maritime security may become the most difficult security challenge for ROK in the years to come. The purpose of this paper is to compare major changes in maritime security affairs of the ROK during last twenty years from 1998 until now(2018). 1998 was when this journal 『Strategy 21』 was published for the first time by the Korea Institute for Maritime Strategy. Then, this paper tries to identify challenges and risks with which this country has to deal for its survival and prosperity, and to propose some recommendations for the government, the Navy, and the Coast Guard as they are responsible for the maritime security of the country. The recommendations of this paper are as follows: strengthen ROK-US alliance and expand security cooperation with regional powers in support of the maintenance of the current security order in the region; building-up of maritime security capacity in preparation for crisis on the maritime domain with the navy targeting to acquire 'a non-nuclear, balance-of-terror capability, to improve interoperability with the Coast Guard based on 'a national fleet,' and to actively pursue innovation in naval science and technology. Finally, this paper proposes that naval capability the country needs in another twenty years depends on how effectively and rigorously the navy put its utmost efforts towards building 'a strongest navy' today.

This study analyzed the relationship between re-applications and the degree of re-applications under the assumption of a complex interaction between the location strategy and the internal capacity of a nursing home. The results of the study are as follows. First, although the relative influence on re-use is greater in hospital internal capacity (${\beta}=0.303$) than in hospital location strategy (${\beta}=0.313$) both factors have a statistically significant effect on the degree of re-use. Second, the importance of location strategy was found to be more important for rehabilitation-enhanced nursing hospitals than for general care (${\beta}=0.43$). It is suggested that detailed preparations should be made based on factors such as location marketability, traffic infrastructure, building sales, and medical concentration. Third, internal hospital capacity did not show any adjustment effects due to hospital type, and it was confirmed that both were important factors for general care and rehabilitation-enhanced hospitals.

The development of construction industry has led to the increase in the number of criteria imposed by project clients for selecting contractors. For example, clients often request tenderers to satisfy various conditions such as tight programme, financial strength, managerial ability, relevant work experiences, technical strength, high workmanship standard, safety requirement, quality specification, and yet others. This trend has attracted research interests of devising various methods for helping project clients to assess contractors' bids. For example, in recent development, the Works Bureau of the Hong Kong Government has introduced two mechanisms in tender evaluation for various public work contracts, namely, the Marking Scheme effective from June 2002 and the Formula Approach effective from November 2002 [1], [2]. These approaches evaluate a contractor's tender by considering collectively its tender price and performance attributes, the latter including contractor experience, past performance, technical resources and technical content of his proposal. The tender with the highest combined price and performance score (CPPS) will be normally recommended for acceptance. It appears, however, that there is little existing research in helping contractors to identify a competition strategy that enables the contractor to offer his most competitive bid collectively taking into account his resource capacities and project client's multiple performance criteria. This paper examines the factors affecting contractor's competition strategy to compete for works in Hong Kong. The understanding about the factors will contribute to identifying effective competition strategy. The data used for the analysis were collected from Hong Kong construction industry. The research findings may provide valuable references for investigating effective competition strategies in other construction industries outside the region.

According to the development of industry, many aspects of society have been changed and a living environment has been more convenient than before. However, factors of fire risk are increased because of society which is becoming complex. Moreover, a building built in recently is becoming high-rise and intelligent. Then losses of life and property increase continually. Thus, an institutional strategy which can solve this problem is needed. The purpose of this research is to state a problem of specific a building managing strategy and suggests a reformation of the fire safety grade system of a specific building. The suggested ideas are an adoption of fire risk evaluation of a building, tentatively named "Fire Safety Corporation" establishment, reclassification of the fire safety grade system of a specific building, and newly making fire safety managers of ultra-high buildings and underground structures.
