Teams play an indispensable role in helping an organization achieve its goal. Since constant interaction among team members is the cornerstone of team competitiveness, it is necessary for the team members to commit themselves to shared goals-team commitment, a type of positive, emotional attitude of team members. Constant interactions among team members, however, inevitably breed a byproduct called conflict. Though intra-team conflict has both positive and negative effects on team performance, little research has been done to clarify the roles that relationship, task and process conflicts play in team commitment. This research is an empirical investigation of the relationship among the three types of conflicts - relationship, task and process conflicts - based on data collected from 232 R&D teams of 13 Korean companies. The analysis suggests that, while relationship conflict has a negative impact on team commitment, task and process conflicts have no significant impact on team commitment. As for the relationships among those three types of conflict, process conflict has positively influenced task, and relationship conflicts and task conflict also has had a positive impact on relationship conflict. Based on these results, this study has presented its implications and directions for future research.

With the recent development of 3D printers, there is a growing need to make them similar to real products. As a result, FDM full-color 3D printers have been developed and actively distributed, but GUI design has fallen short of that, causing confusion among users. Accordingly, this study conducted a literature survey, and through a case study, the current status of FDM full-color 3D printers was identified and the components of GUI design were analyzed based on prior research. The draft checklist was drawn up according to the components of the derived GUI design, and 24 items were deleted through the three Delphi surveys and the validity of the remaining 26 items was verified. As a result, the layout should consist of intuitive screen configuration and menus with high frequency of use, and the text should be intuitive and clearly communicated. In addition, the icon should be placed in a visible position and used in real life to image it. Finally, we could see that the color should be used to give feedback to the user using the highlight color and not overlap the output.

The peel from seven types of citrus was extracted with 80% methanol, and their phenolic compound content, oxygen radical absorbance capacity (ORAC), inhibitory activities of nitric oxide (NO), and reactive oxygen species (ROS) production induced by LPS and t-BHP in LPS-activated RAW 264.7 cells were measured. Total phenolic content was high in Yungkyool, Cheonhyehyang, and Jinkyool (30.6, 30.2, and 28.2 mg GAE/g, respectively), while total flavonoid content was high in Yungkyool and Jinkyool (30.3 and 25.5 mg RE/g, respectively). ORAC was the highest at 1,076 mM TE/g in Yungkyool, followed by Cheonhyehyang (1,012), Jinkyool (984), and Hallabong (914). High inhibitory activity against NO production was shown in Cheonhyehyang, Yungkyool, and Jinkyool with $IC_{50}$ values of 215.3, 259.2, and 328.9 ${\mu}g/mL$, respectively. LPS-induced ROS production was inhibited by 16.4% and 12.8% in Hallabong and Jinkyool, while t-BHP-induced ROS production was inhibited by 28.7%, 26.1%, and 26.6% in Jinkyool, Hallabong, and Cheonhyehyang, respectively. Correlation coefficients between total phenolic, total flavonoid content, and ORAC were 0.884 and 0.855. Inhibitory activity against NO production showed higher correlation with total phenolic content than total flavonoid content. It was concluded that citrus peels had potent antioxidant activities and could be used as natural antioxidants in the food and pharmaceutical industries.

Owners' efforts to acquire Green building certification, which started in 2002, have been rapidly increasing since 2006. The causes of the increased owners' interests are due to various incentives, legal obligation, and purpose of advertising. As project owners generally are deficient in capabilities and knowledge on how to deal with administrative works on certification, they tend to fulfill the minimum requirements for certification. However, effective administration process need capabilities of identifying individual making decision point and review information. The implementation of green building certification system is expected to provide comfort to both occupants and potential users. Furthermore it contributes to reducing energy costs throughout the phase of O&M. In addition, technology innovation in green industry can be obtained. Therefore, this study is intended to support owners in order that they can clarify certification tasks and make a rational decision-making in time. For this purpose, first of all, the major decision points were selected as the gateways of green building certification process. And then management system based on IDEF3 modeling was developed for supporting owners' decision-making performance. This management system will improve owners' overall capacity in handling all the tasks regarding the certification of Green building.

The development in information technology allowed most of the information around us into digital information, in other words, a database. The innovation increased the accessibility and helped this society change into an informational age. However, there is a shortcoming of this open source as the users have difficulty in assorting the information that s/he needs and realizing if the information provided is important. Therefore, the need for search engine has risen in such a way to increase the accessibility and facilitation of information provided to the users through searching the necessary information in the database by an easy and accurate way. This study aims to increase the utilization of search engine through relationship analysis between purpose of user and interface design factors of search engine. Also, it intends to propose design guidelines for search engine interface design in order to increase user satisfaction and usability. This study categorized and correlated the relationships of the purpose in using the search engine and types of search engine interfaces. This study explicates the critical properties in designing each search engine interface according to the purpose of the users in using them. Also, this study proposes recommendations for appropriate design guidelines for search engine interface and effective advertisement use through properties of interface and their importance. The search engine interface suggested from the result provides interface that allows efficient search for desired information and embrace a variety in users, eventually increasing the usability in search engine.

The efficient algorithms are suggested in this study for solving the multicommodity network flow problems applied to Communications Systems. These problems are typical NP-complete optimization problems that require integer solution and in which the computational complexity increases numerically in appropriate with the problem size. Although the suggested algorithms are not absolutely optimal, they are developed for computationally efficient and produce near-optimal and primal integral solutions. We supplement the traditional Lagrangian method with a price-directive decomposition. It proceeded as follows. First, A primal heuristic from which good initial feasible solutions can be obtained is developed. Second, the dual is initialized using marginal values from the primal heuristic. Generally, the Lagrangian optimization is conducted from a naive dual solution which is set as ${\lambda}=0$. The dual optimization converged very slowly because these values have sort of gaps from the optimum. Better dual solutions improve the primal solution, and better primal bounds improve the step size used by the dual optimization. Third, a limitation that the Lagrangian decomposition approach has Is dealt with. Because this method is dual based, the solution need not converge to the optimal solution in the multicommodity network problem. So as to adjust relaxed solution to a feasible one, we made efficient re-allocation heuristic. In addition, the computational performances of various versions of the developed algorithms are compared and evaluated. First, commercial LP software, LINGO 4.0 extended version for LINDO system is utilized for the purpose of implementation that is robust and efficient. Tested problem sets are generated randomly Numerical results on randomly generated examples demonstrate that our algorithm is near-optimal (< 2% from the optimum) and has a quite computational efficiency.

Korea is a country having shortage of natural resources, but to overcome this issue and to nurture national competitiveness it is challenging for national-lead economic policy, citizen's dedicated efforts and technological innovation for achieving economic growth. Since the financial crisis, the government has boldly promoted policies to nurture venture companies to make structural adjustments for the sophistication of the industrial structure and job creation. Various policies for establishing the foundation of the entrepreneurial ecosystem in which the process of start-up, growth, recovery and reinvest are virtually circulated are presented by the Business Incubators. Recently the Business Incubators neither present a direction differentiated from the vocation of Business Incubator, and nor the operating methods for leading the changing of Business Incubator environment, which threatening the role of Incubating and growing early startup companies. In order to explore the development change of the business incubator, in this research we analyzed the published papers from 1998 to 2016 of business incubator government polices, research methods, related research topics and other major variables. The analysis of the research trends of business incubator revealed the lack of depth case studies, diversity of research topics, and the study of certain limited variables. For the development of the business incubator, case studies of the institutions which carried out excellent incubator and research on the incubation system of the institutions, that are similar to the incubation center are required. This research suggest further research on the case studies of excellent business incubator and agencies, and the center director and manager, which is the center of human resources, and hopes for the revitalization of business incubator researches.

Many preliminary entrepreneurs are ready to start a business in every year. However, starting and preparing business have a lot of difficulties. Entrepreneurship is the most important factor for overcoming these difficulties. But, it is not easy to understand entrepreneurship to founders despite many research scholars. In this paper, we are focused on easy understanding of entrepreneurs. Instead of vague theories, we analyzed selected two companies in Korea. From the beginning until now, these companies have founders entrepreneurship and organization entrepreneurship. we studied these entrepreneurship factors with other Various causes. Analysis of two cases is summarized into three type. First, both companies had well-founded internal network system. Trained employees in internal network were flexible to meet the market conditions. Also, network effect made that employees can offer their idea and make discussions. Second, The company quickly recognized for organizational culture despite of most other companies recent awareness. This factor was the basic driving force for solving human resource management problem of small size companies. final factor is innovation capacity of these companies. Financial difficulties experienced of establishment is common to every company. However, two companies has continued to invest research and development despite of this financial problem. As a result, intellectual property management was accepted, as well as technology development. Clearly, these three factors are consistently applied since established and led to the company's continued growth and success.
