케이블을 이용하여 장경간을 필요로 하는 교량의 시공은 일반적으로 불완전 한 구조계인 교량의 선단에 데릭 혹은 무한궤도 크레인을 설치하여 수상 및 육상으로 이송되는 교량 상판을 리프팅하여 시공하게 된다. 이와 같은 경우 일차적으로 과도한 크레인의 자중으로 인하여 불완전한 구조계에 결함을 발생시킬 수 있으며, 또한 하부 수송으로 인한 추가 비용 및 공기를 소요하게 된다. 본 연구에서는 이러한 기존 시공방법을 개선하고자 개발된 교량 일 측에 편중 가능하고, 가동 붐을 설치하여 후방 이송 자재를 시공 지점으로 운반, 가설이 가능한 데릭 크레인의 시공 단계를 정의하여 수치해석을 수행하였다. 데릭 크레인의 하중 재하 점을 고정부 4점으로 단순화하였으며, 가동 붐의 수직/수평 회전 범위를 고려하여 반력을 산정하였다. 또한 크레인의 '휴지' 및 '작업 중'의 단계로 나누어 가동 붐 및 강형, PC Slab에 의하여 발생하는 휨 모멘트를 시공단계에 반영하였다. 본 연구에 고려된 데릭 크레인은 접속교를 통한 육상 작업으로 시공 기간 및 비용을 줄일 수 있으며, 크레인 자체의 작은 중량으로 시공 중 재하 하중 감소를 꾀할 수 있다.

The purpose of this study is to derive the factors for the general consumers to choose the store to buy seafood. Survey on 414 general consumers by questionnaires was conducted to find out the factors for them to choose the stores in the traditional market and large supermarket, and through the analysis on the results the factors for general consumers to choose large supermarkets were derived when they buy seafood and at the same time the degree of its importance was analyzed. The results of the survey showed that the general consumers chose large supermarkets to buy seafood despite the fact that they recognized the seafood prices are lower in the traditional markets than in the large supermarkets. Particularly, the results of analyzing the sixteen criteria for choosing the store in which to buy seafood were grouped into four: the 'assortment of goods and high quality', 'service', 'price and promotion' and 'convenient accessibility.' The results of examining the order of priority based on the four factors showed that the 'assortment of diverse seafood and high quality' was found to be given the first priority, followed by 'convenient accessibility' and 'prices and promotion factors', with 'service' being statistically insignificant. Based on these results, Monroe (1975)'s consumers' store choice process is summarized as follows. Before buying seafood, the consumers who use large supermarkets have the desire for buying seafood and then judge the properties of the store which they will use. In this process, consumers were satisfying their needs in large supermarkets in the criteria of 'assortment of diverse seafood and high quality', convenient accessibility', and 'prices and promotion factors' which were found to be statistically significant in this research. Accordingly, the general consumers choose to buy seafood in large supermarkets rather than in the traditional markets. The general consumers were more satisfied with using large supermarkets than using traditional markets, so after they have initially bought seafood in the large supermarkets, they habitually buy seafood in the large supermarkets without going through Monroe (1975)'s 'eight stage process for the store choice.' When such habitual store choice behavior continues for a long time, it results in becoming structural.

Using primary data collected through semi-structured interviews conducted during February 2019, this article examines citizen's awareness and knowledge of Khon Kaen Smart City (KKSC) among the residents of five contiguous municipalities within Khon Kaen Province, Thailand. A self-weighted sample of 420 respondents was selected through a two-stage, 30-cluster sampling process. In the first stage, a sample of 30 artificial clusters of 100 households each was selected. In the second, 14 households were randomly selected from each of these clusters. The head of household or, if unavailable, a resident aged 18 or over was interviewed. The study applies the "citizens as democratic participants" dimension of Simonofski et al.'s (2019) evaluative framework. Results found that, because of ineffective citizen engagement, the levels of awareness and knowledge about KKSC were low. However, multiple logistic regression found that, despite the low levels of awareness and knowledge, education and income could establish an independent effect on awareness of KKSC. Those who completed post-secondary school were more aware of KKSC than those who finished only secondary or primary education. Similarly, the analysis of data clearly indicated that educational attainment, solely and independently from all other socio-economic and demographic variables, could explain the positive effect of education on knowledge about KKSC.

Although service innovation is not a new concept, innovation research in general tends to focus on technological innovation by manufacturing firms. With this view, innovation studies focus on product(e.g., goods) and process(e.g., product systems) innovation, ignoring service innovation and its inherent opportunities. Since major economy has been transformed to service economy, service innovation is considered a new effective way to sustain and gain a competitive advantage. Service innovation is no longer regarded merely as a side activity to product innovation; it has become a main research topic in its own right, accompanied by an increasing focus on services. While the number of service innovation studies has increased dramatically in the past 30 years in international research, few studies have been performed in domestic studies because domestic service innovation research began from the middle of 2000. In addition, there are no comprehensive literature reviews describing the evolution of service innovation research in both international and domestic studies because of the heterogeneities of service industry and multidiscipline characteristics of service innovation studies. To bridge this research gap, the purpose of this paper is to perform an extensive literature review and synthesis to enable a critical review of extant research on service innovation and trace its evolution, which will establish a foundation for further studies. By reviewing 169 articles (136 international papers; 33 domestic papers) published between 2000 and 2014 (in past 15 years), primarily in leading service, innovation and management information systems journals, this study analyzes the progression of service innovation research according to the four aspects such as number of studies, topics, methodologies and target industries. Overall, the view of service innovation has evolved, from a complement of traditional product innovation to a multidimensional, all-encompassing concept that entails several functions, both within and outside the firms. The results showed that domestic research still stays at the formation phase of service innovation studies although international research is in the maturity or multidimensional phase. We found increasing recent activities pertaining to service innovation, resulting from the increasing interest in services innovation across various industries and the links of new topics to the service innovation concept in both international and domestic studies. However, the main focus of service innovation research showed a different propensity between international and domestic studies: the former mainly focuses on a much more diversified pattern, emphasizing the linkages between service innovation and business strategy while the latter mainly focuses on the service innovation process(system) and service design. In addition, there are many case studies in domestic studies while many empirical studies in international studies. Domestic studies should increases the understanding of the interplay between service innovation and product innovation within manufacturing firms. Furthermore, rather than focusing on intrinsic distinctions between service innovation and product innovation, researchers should strive to develop and conceptualize service innovation in domestics studies. The present research also provides useful implications for practitioners. First, this study contributes to expand the current understanding of service innovation research by performing an extensive literature review. Second, tracing and comparing the progression and trends of service innovation research between international and domestic studies, this study showed the similarities and differences between them, which provide practical guidance on future research directions and research agenda. Third, this study performed literature review establishing the analysis system in the initial stage and using them to analyze articles, which is leading to explain the research review of service innovation more systematically and objectively. Finally, this study suggests the domestic researchers their future interests and topics of service innovation research.

Rating systems of bevel gears(straight, spiral, and zerol bevel gears) which are commonly used as power transmission devices for non-parallel axes are developed on the personal computer, which analyze and/or evaluate the gear design and the service performance at the point of view of strength and durability. The typical considerations of the ratings are the bending strength the surface durability, and the scoring resistance. The ratings are carried out using the reliable standards of AGMA & Gleason Works. Therefore, the system is built so that the variables or factors considered differently in those standards and the strength, durability, and scoring partially in Gleason are appraised separatedly by each method, and a series of the estimation processes is integrated into the system so as to compare each result. The developed rating system can be used in the initial stage of gear design process, and also a better design can be performed by the evaluation of the initial design at the view point of gear strength and durability. Additionally, it is useful for the trouble-shooting of bevel gear systems and to the purpose of introducing the methods for maintaining design strength in service with appraising the gear strength after design or with appraising the influencing factors, as a whole. Therefore, this rating systems can help the aim of design automation of bevel gears.

The current evaluation time period for the construction management service is the project completion or after project completion. Therefore, the construction manager has the following problems. First, it is difficult to prepare the evaluation due to the new field movement of the existing participating engineer. Next, the CM work is complex as well as extensive. Therefore, the critical success factors of the construction technology services evaluation are required as a systematic performance standard of CM work. In this study, we extracted the critical success factors that can systematically prepare the evaluation from the early stage of the project through in - depth interviews with experts. And, this study was analyze the priority of each factor by using AHP technique. As a result, the most important factors were related to the systemization of the preparation process, the construction manager work capabilities and practical construction management. And the priorities of all factors were analyzed high in the factors suggested by the owner groups. The results of this analysis are expected to provide the standards that construction management service performer carry out structured management of construction management throughout the project.
