While software globalization is becoming more important, little research has been undertaken into what is meant by globalization and the degree of globalization capability in the Korean software industry. A survey study was conducted among software engineering professionals, gathering the data from 31 IT companies across 7 large-scale projects in Korea. The results indicate that the evaluation score for globalization capability is 2.51 out of 5 points, which is the lowest compared to other areas of software engineering such as team capability (2.88), process and tool supports (2.96), project management (2.97) and development (3.64). We also discuss how to introduce software globalization technologies in Korea based on the successful experiences of leading global IT companies.

A new UV-curable coating was carried out to impart the flame-retardant property to cotton fabric using Bis[2-(methacryloyloxy)ehtyl]phosphate(DMEP) and 2-hydroxy-2-methyl-1-phenyl-propan-l-one(HMPP) as a UV-curable monomer and a photoinitiator, respectively. The cotton fabrics were applied with various amounts of DMEP and HMPP via padding and UV irradiation, and the optimal concentrations of DMEP and HMPP in the formulation were 40%(w/w) and 7%omp respectively. A limiteed oxygen index(LOI) up to 28.9 was obtained for the UV-cured fabric, which may occur through a condensed phase mechanism as verified by the increased residue number with increased application level. The characterization of the UV-cured coating was made by IR analysis, thermo-gravimetric analysis, LOI test, and scanning electron microscopy.

The Construction Workers Mutual Aid Association is carrying out a number of strategic tasks with the goal of "contributing to improving employment and stabilizing the return of workers to construction workers through employment welfare and retirement deduction services." One of them is the retirement deduction system. The retirement allowance system is a system for the retirement income and livelihood security of construction workers who are not adequately protected by the Labor Standards Act, such as retirement allowances due to the nature of day labor. The Construction Workers Mutual Aid Association has promoted the introduction of electronic manpower management. For the efficient management of the pilot sites and the plans for the future, comprehensive evaluation of the pilot sites as well as the evaluation of the status and operation results of each pilot project site are needed. Therefore, in this study, we will develop performance indicators to evaluate the current state of electronic manpower pilot projects and analyze the actual situation of pilot project sites through actual application, and try to derive future implementation strategies.

This study aimed to understand the current status of science and engineering university(SEU) R&D operations depending on the research project characteristics(e.g., stages and characteristics), then provide implications for future university R&D support systems and related policies. Hence, an online survey targeting SEU R&D recipients was conducted between October 4th to November 5th, 2021. Analyzing 445 valid data using the Apriori algorithm, 16 association rules for R&D operation according to the research project characteristics show that regardless of research characteristics, SEU's R&D projects, particularly in applied research, were funded or operated under the leadership of government or public institutions. For basic research, individual researchers had a higher level of autonomy in determining research topics; yet, they had a short duration (3 years) and a unit of evaluation period of more than 3 years. These findings can be empirical evidence for revealing the relationship among various variables in operating SEUs' R&D.

Urban renovation projects (reconstruction and redevelopment) have a longer licensing period than general housing projects, and many consultations with the licensing authorities require expertise. Most of the members of the union do not have basic knowledge of the maintenance business, so they have a lot of authority to promote smooth business Is entrusted to the union leader. However, contrary to the original purpose entrusted by the members, it is easy to find a case where the business is suspended because the union leader is exposed to corruption for the private interests of the union, and the members' disputes could not be resolved. In order to overcome this risk, the problem of the maintenance project was found through a questionnaire survey composed of practical experts, and a solution was presented through the KCSI evaluation model. This study mentioned the necessity of a responsible CM that can make independent business decisions without interference from the union, rather than a management-type CM limited to the cooperative's work assistance. In order to promote the construction industry's national role, it was necessary to revitalize responsible CM, so six practical alternatives were proposed.

In the face of the deterioration of tobacco manufacturing plant, we've got the plan for now manufacturing factory for the competitiveness, modernization, rationalization and environment. To achieve the goals, it was necessary to plan and investigate in the early stage of project. Consequently. We determined to introduce the CM in the early stage. We Performed the whole phase of CM services front the pre design phase services like feasibility analysis of site and building, plant master plan, selection of manufacturing facilities and drawing up the RFP, to maintenance management phase after the completion of a construction work. Contrary to the another CM projects, YongJu New Tobacco Manufacturing Plant CM organized the CM team with expert in field before the design development. This study analyze and evaluate the CM services of YongJu project which performed on the pre design phase. The purpose of this study is to emphasize the importance of pre design phase CM and support that CM services will start from the pre design phase.

Purpose: This paper provides an idea on the future prospect for change in steps of the six sigma DMAIC project under the environment of the 4th industrial revolution. Methods: First, the purpose and activities required in each step of DMAIC are reviewed. Next, activities are reviewed together with tools and techniques, considering the purpose and the environmental changes of the 4th Industrial Revolution. Finally, the best approaches for achieving the purpose are prospected to get an idea on future change. Results: The purpose of each phase of DMAIC is expected to remain unchanged. But activities, techniques, or methods will be replaced with more effective and efficient ones. Also, many activities may possibly be executed by a system instead of people like BB, GB or team members. Moreover, DMAIC may not be a project any more but a routine job of the system in the future. Conclusion: Under the environment of the 4th industrial revolution, many activities including analyzing various types of data and extracting valuable information, will be executed by a system with proper algorithms instead of people. And six sigma improvement projects may be intrinsic parts of the system and may not exist as separate projects any more.

Since the ratification of the Paris Agreement (COP21), the government is continuously strengthening policies for the reduction of greenhouse gas of the construction industry in accordance with the growing importance of reducing greenhouse gas and obligation of the government. Especially, the government emphasizes the need to improve the energy performance of old public buildings. Since 2014, the government is running a pilot project in which the government supports the construction cost of the green remodeling project of old public buildings and it is intended to develop the best practice of green remodeling and activate the green remodeling in the private sector. In this study, we analyzed the economical efficiency of the old public buildings by each level through green remodeling and conducted building related investigation and equipment measurement to plan the alternatives of the corresponding buildings. The improvement plan is a green remodeling plan that integrates alternatives. Five improvement plans were developed for each level to analyze the economic feasibility of each plan. As for the analysis method, the first energy demand amount calculation and the LCC analysis were performed through ECO2. In the LCC aspect, the improved 3/4 plan (middle level plan) was the most excellent and results were obtained in the order of the highest cost plan followed by the lowest cost plan. As a result, it is expected that it can be utilized as a basic data for future green remodeling performance plan and economic feasibility analysis in the future.

According to the climate change scenarios, the intensity of typhoons, a major factor in Korea's natural disaster, is expected to increase. The increase in typhoon intensity leads to a rise in wave heights, which is likely to cause large-scale disasters in coastal regions with high populations and building density for dwelling, industry, and tourism. This study, therefore, analyzed observation data of the Donghae ocean data buoy and conducted a numerical model simulation for wave estimations for the typhoon MAYSAK (202009) period, which showed the maximum significant wave height. The boundary conditions for wave simulations were a JMA-MSM wind field and a wind field applying the typhoon central pressure reduction rate in the SSP5-8.5 climate change scenario. As a result of the wave simulations, the wave height in front of the breakwater at Sokcho port was increased by 15.27% from 4.06 m to 4.68 m in the SSP5-8.5 scenario. Furthermore, the return period at the location of 147-2 grid point of deep-sea design wave was calculated to increase at least twice, it is necessary to improve the deep-sea design wave of return period of 50-year, which is prescriptively applied when designing coastal structures.
