Building industry clients are suggested to clarify requirements and needs properly at the pre-project stage. According to these they can develop options to meet their needs with considering their resources and business case. At this stage, they make decisions while professionals in the industry are not involving. This process is called client briefing at the pre-project stage. However, client briefing is not a discrete process only conducted at this stage; various clients briefings should be performed over a project lift cycle. The client briefing at the pre-project stage is more important than others as the value for the clients is clarified at this stage - they may not be satisfied for the project results even when the project is finished on time within budget if the value itself is incorrectly defined. Given that the client briefing is important as stated, this paper aims to review theory on client briefing focusing those at the pre-project stage. As a part of research, a prototype workshop for client briefing is held and findings from it are summarized. Finally, suggestions for conducting client briefing in Korea are presented in terms of directions of relevant research, systems in the industry and points that clients or client briefing consultants should consider.

Digital manufacturing (DM) technology helps engineers design products promptly and reliably at low production cost by simulating a manufacturing process and the material behavior of a product in use, based on three-dimensional digital modeling. The computing infrastructure for digital manufacturing, however, is usually expensive and, at present, the number of professional design engineers who can take advantage of this technology to a product design accurately is insufficient, particularly in small and medium manufacturing companies. Considering this, the Korea Institute of Science and Technology Information (KISTI) and H University is operating a DM track in the form of Industry-University-Research Institute collaboration to train high-performance-computing-based DM professionals. In this paper, a series of courses to train students to work directly into DM practice in industry after graduation is reported. The operating cases of the DM track for two years since 2013 are presented by focusing on the progress in establishment, lecture and practice contents, evaluation of students, and course quality improvement. Overall, the track management, curriculum management, learning achievement of students have been successful. By expediting more active participation of the students in the track and providing more internship and job offers in the participating companies in addition to collaborative capstone design projects, the track can be expanded by fostering a nationwide training network.

In 2012, Korean overseas construction market has achieved 64.9 billion dollars of contract order and its amount has increased since the mid 2000's. However, importance of qualitative growth based on profitability as well as quantitative growth is also emphasized. This study analyzed overseas plant project's subcontract process management which is closely related to cost management as one of the qualitative growth methods. In order to select major subcontract processes, extensive literature review and focus group interview(FGI) were implemented and then professionals with years of experience in the overseas plant projects were participated in the questionnaire survey. The collected data were analyzed by Benefit-Structure Analysis(BSA) model. The findings of this study include: (1) the seven and six subcontract processes are positioned in the area of importance control factor and in the area of maintenance/control factor, respectively; (2) administration capability attainment is needed for the six subcontract processes in the area of importance control factor and sustainable management system is required for the processes in the maintenance/control factor area. The further research will identify key subcontract processes to be managed for overseas plant projects by Korean EPC contractors based on the findings of this research.

The number of construction management firms has been increased as construction management delivery system has been active in Korean construction market. the capability of leading construction management professional, who is responsible for managing project administration, is important for commissioning construction management contracts. The quality of project proposal and the capability of leading construction management professional, which are assessed by the board of contract awarding committee, are the major contributors for commissioning the public construction management projects administered by the Korean public procurement service for contracting. Therefore, employing a very competent leading construction management professional is the critical strategy for awarding contract to the construction management firms' part. That is why the firms should secure a fixed number of leading construction management professional in a waiting list to proceed the contract commissioning process for expectant candidate projects, even if there is no project assignable to the leading construction management professionals. However, a measure that makes effectively use of the leading construction management professional in a waiting list has not been systematically implemented in the firms. In turn, the firm suffers considerable loss in a project personnel supply and demand plan. Expert opinions were obtained by the survey questionaries administered to top management of the construction management firms which are engaged in the construction management contracts for commissioning the public construction management projects administered by the Korean public procurement service either as principal or co-principal deliverer. This paper presents the findings obtained by investigating the actual employment state of the leading construction management professional in the waiting list and by analyzing the issues involved in mobilizing and demobilizing them. It contributes to implement a practical guide for searching effective solutions to the issues.

This study has investigated shipping finance systems in Korea and China, and extracted negative factors based on it to propose a way to develop the shipping financial system in Korea for shipbuilding industry and marine transportation. From after the global financial crisis in 2008 to right before the Lehman Brothers Holdings bankruptcy, shipping finance has been dominated by the major industrialized countries in Europe. However, the weight point is moving to the countries in Asia region such as Korea, Japan, and China based on relatively strong banking system and low interests rate. This study focused on the alternatives the current situation that the starter of shipping finance among three countries in Northeast Asia, South Korea is facing China's challenges. In the paper, shipping finance in Korea presented its defectives such as the limits of ship financing, lack of professional workforces, ever-present foreign exchange risks, and lack of understandings of the parties. As the countermeasures of them, it proposed establishing professional institute for ship financing, training professionals in financial industry, raising foreign credentials of won, and continuing associations between the parties. Even though we are the first Asian country introduced ship funds, the ship funds growth in China shall be under our eyes while we keep systemic networks between shipping, ship building, and ship financing.

The purpose of this study is to provide basic data that can be used in a reasonable assessment of the learning outcomes of STEAM. It presented a learning outcome evaluation method, relative weights of key competencies standard that a learner should cultivate. For this study, a pairwise comparison questionnaire about the key competencies was conducted on the STEAM professionals, and AHP was applied to analyze the priority of main factors of key competencies. The results of this study are as follows. First, the importance of capabilities of convergence accomplishment and capabilities of convergent cognition, in the first layer of key competencies, were 39.4% and 36.8%, respectively. In the education evaluation of the STEAM, capabilities of convergence accomplishment and capabilities of convergent cognition showed similar level of importance, and were considered more important factor than capabilities of convergence attitude (23.8%). Second, the relative importance of capabilities of problem solving (20.0%) was highest in the second layer of key competencies, and followed by capabilities of creative thinking (18.3%), responsibility (15.3%), and understanding convergence knowledge (11.0%). Third, it will be a foundation of a competency evaluation, which reasonably evaluates, based on the relative weights, whether to accomplish educational objectives of the STEAM program In addition, this results is expected to become a guide to develop an education program that can improve the teaching and learning process and raise the learning outcome, as well as an education evaluation of the STEAM.

Research in detecting fake information gained a lot of interest after the US presidential election in 2016. Information from unknown sources are produced in the shape of news, and its rapid spread is fueled by the interest of public drawn to stimulating and interesting issues. In addition, the wide use of mass communication platforms such as social network services makes this phenomenon worse. Poynter Institute created the International Fact Checking Network (IFCN) to provide guidelines for judging the facts of skilled professionals and releasing "Code of Ethics" for fact check agencies. However, this type of approach is costly because of the large number of experts required to test authenticity of each article. Therefore, research in automated fake news detection technology that can efficiently identify it is gaining more attention. In this paper, we investigate fake news detection systems and researches that are rapidly developing, mainly thanks to recent advances in deep learning technology. In addition, we also organize shared tasks and training corpus that are released in various forms, so that researchers can easily participate in this field, which deserves a lot of research effort.

In this paper, big data analysis was conducted for past and present fashion trends and fashion cycle. We focused on daily look for ordinary people instead of the fashion professionals and fashion show. Using the social matrix tool, Textom, we performed frequency analysis, N-gram analysis, network analysis and structural equivalence analysis on the big data containing fashion trends and cycles. The results are as follows. First, this study extracted the major key words related to fashion trends for the daily look from the past(1980s, 1990s) and the present(2019 and 2020). Second, the frequence analysis and N-gram analysis showed that the fashion cycle has shorten to 30-40 years. Third, the structural equivalence analysis found the four representative clusters. The past four clusters are jean, retro codi, athleisure look, celebrity retro and the present clusters are retro, newtro, lady chic, retro futurism. Fourth, through the network analysis and N-gram analysis, it turned out that the past fashion is reproduced and evolves to the current fashion with certain reasoning.

In Korea, public infrastructure projects employ "long term continuation (LTC) contracts," which require budgets to be reevaluated and re-appropriated annually throughout the multi-year life of the project. However, such contracts also make it susceptible to frequently changing government policies, in which budgets required for existing projects are allocated to new projects and thus does not provide a consistent stream of capital to multi-year projects. Each year, the KEC needs to attain government funds for construction of its multiple highway construction sites. Because it is difficult to know the amount that may be actually appropriated to KEC in a given year, it is in turn difficult to anticipate and provide sufficient funds necessary for construction to run smoothly and continuously. The lack of a good logic for appropriation has resulted in projects having a skewed distribution of capital. To get better budget appropriations from the central government, the KEC first needs a systemized approach that rationalizes the annual construction capital optimally required for its individual sites. The goal of this research was to devise a way that allows the KEC to determine and calculate the optimal construction costs that would be required for its individual construction sites on an annual basis. Both the optimal progress rate and the essential work types were assessed through a workshop with 24 professionals (KEC employees and contractors) who had extensive experience in KEC projects and also were currently working in these projects.

Objectives: In this study, knowledge of environmental disease, experience of environmental health education and necessity of environmental health education of elementary school pupils were compared and analyzed. Methods: The population of this study was from grade 1 to 6 elementary school pupils in Ulsan city, Korea. Five elementary schools were randomly selected from Ulsan City. Seven hundred and twenty-eight responses from the five schools were analyzed (seventy-two were excluded). A self-administered questionnaire measuring sociodemographic variables, Knowledge of environment related disease(atopic dermatitis, asthma etc), as well as educational experience and necessity of environmental health education was analyzed. The survey results were analyzed using SPSS-PC Program 12.0 and the following results by implementing Frequency Analysis, Cross-tabulation Analysis and ANOVA are as follows. Result: Pupils of lower grades more informed than those of higher grades about atopic dermatitis. Among asthma sufferers, many responded that symptoms occurred or improved during the lower grades of elementary school. In terms of the lifestyles of patients with atopic dermatitis or asthma, female pupils, especially those in the lower grades, tended to make changes in their daily habits based on their disease. Also, parents tended to intervene/mediate more in the dietary habits and personal hygiene habits of lower-grade pupils compared to their higher-grade counterparts. Personal hygiene education is currently not provided in schools, and upper-grade pupils have more experience with personal hygiene education compared to lower grade pupils. 430 (59.0%) of pupils replied that education about personal hygiene is necessary in their curriculum. 490 (67.3%) of elementary pupils are aware of the close connection between education in hygiene and human health. When asked if education in hygiene should also be undertaken by teachers and parents, 406 (55.7%) students said that it should be done. Conclusions: Developing a concrete health education program and raising instructors' awareness of the necessity for education in hygiene. Placement of professionals in the personal hygiene education field, is important to provide good health education for elementary school pupils.
