리그 오브 레전드, 히어로즈 오브 더 스톰 등으로 대변되는 다자 온라인 전투 게임(MOBA)은 PC 버전에서 우리 게이머가 아주 많이 플레이하는 장르이다. 본 논문은 이 장르의 모바일 버전인 2017년작 펜타스톰의 사용자 인터페이스를 PC 버전의 인터페이스와 물리적 구조 및 기능성에 대해 비교 분석하고 코호넨의 휴리스틱에 기초한 사용자 인터페이스의 조작 편의성에 집중한 설문 조사를 통해 펜타스톰 사용자 인터페이스의 만족도와 개선 방향을 살펴보았다. 4점 척도로 적극적 평가를 요구한 8개의 설문에서 펜타스톰 사용자 인터페이스는 5개 부문에서 80% 이상의 긍정률을 보였지만 아이템 구매 관련은 호불호가 갈렸고 캐릭터 동선과 상대 지정 부분은 상대적으로 낮은 긍정률을 보여 개선의 필요성을 나타냈다.

Today, Organizations should be equipped with flexibility in order to cope with rapidly changing environment in management. By doing so, they are able to grow and obtain their superior competitiveness in highly developed economic arena. Recently, Enterprise Architecture is actively constructed to perform such a change flexibly. In this regard, it is crucial to figure out some risk factors for the organizations that place an order. Besides, it is also important to find out the quality of EA and some risk factors caused by the organizations that receive an order. Lastly, it is absolutely important to verify the relationship between such factors and outcomes of EA. In this aspect, this study will verify risk factors made by the former organizations and investigate the quality of EA and its outcome by proving the said relationship. In doing so, it will suggest an appropriate direction for the companies that will build up or perform EA successfully.

Many mid-sized companies in Korean automotive industry have attempted to solve the lack of human power, to control the quality of components, to improve the production rate, and to innovate the manufacturing line. The goals of this study are to analyze the production rate of an automotive component manufacturing line using simulation software, to construct a Flexible Automation Subassembly (FAS) system and to suggest an optimized layout design using FAS line. In this research, the simulation model for manufacturing line was developed and used the realistic data of a medium sized company in Korean automotive industry. To complete this research, a simulation software 'ARENA' was used. This research analyzed the work distribution strategy and cycle time element for production flow and proposed an optimized layout to resolve line balancing problem which would bring the improved production rate.

While many surveys show very positive attitudes on the part of consumers towards eco-friendly products, the market share actually reflecting green IT purchases remains low in most countries. The motivations behind green IT purchase behavior are still obscure. Several studies have addressed the question of green IT diffusion from economic and normative viewpoints in an attempt to interpret IT adoption behavior. This study comes at the question from a different angle, namely negative frame, examining threat and coping behaviors using the Ordered Protection Motivation (OPM) model and threat appraisal theory. The results show that attitudes toward fairness and positive change, which are precedents of threat appraisal, play an important role in determining threat appraisal. Perceived threats in the green IT arena include habit change and ecological change. Appraisal for coping with these threats directly affects initial adoption behaviors regarding available green IT, and then indirectly encourages the purchase of new green IT products.

MOBA (Multiplayer Online Battle Arena) 기반의 게임 서비스는 현재 가장 관심을 받고 있는 게임 장르의 한 종류이다. MOBA 장르와 같은 게임들은 플레이어의 실력도 중요하지만 같은 팀원간의 협력과 전략이 중요한 요소 중에 하나이다. 이러한 상황에서 악의적의 의도로 자신의 비정상적인 플레이를 한다거나 욕설 등의 팀의 사기를 저하시키는 플레이어들이 문제가 되고 있다. 이러한 플레이어들의 제재를 위해 몇 가지 시스템들이 제안 되고 있지만 그들에 대한 판단은 쉽지 않다. 그래서 본 논문에서는 PageRank 를 기반으로 하는 불량 플레이어의 판단에 대한 보조 시스템을 제안 한다. 이 시스템의 MOBA 게임 플레이어의 플레이 횟수, 신고 횟수, 신고 받은 횟수 등의 자료들을 이용하여 플레이어의 Judgment Points 와 Bad Player 지수를 파악하며 이를 기반으로 생성된 Bad Player 랭킹을 통하여 불량 플레이어 검색에 도움을 줄 것으로 예상된다.

This research was conducted to estimate the use and preservation values of Jirisan national park, using a dichotomous choice contingent valuation. Jirisan national park was estimated to have the use value of 6,377 won per visitor. In terms of preservation value was estimated 13,030 won per housed per year. The results of this research show that Jirisan national park generated considerable use and preservation values, exceeding far greater than current admission fees. The findings also indicate that the estimated economic value provides enough justification for the national park service to increase admission fees in order to maintain the quality of the natural environment. This result may contribute to guidance on the pricing policy of national park managers and practitioners, although public policy may be made in the political arena.

The distribution cost increases constantly because of the growth of yield, globalization of accounts and the generalization of e-commerce. This paper is concerned with scheduling on the allocation of workers to maximize the amount of order process in warehouse logistics system. The problem is to determine the number of operators in each process by the sequential time zone. We considered that the number of operators is restricted to the current level and also the process time is changed by putting some resources into the process. In each stage, we suggest some considerations for the allocation of workers and estimate the maximum amount of order process of the alternatives. We analyzed the alternatives using simulation s/w Arena with real cases.

The competition between companies for prior occupation of the market is becoming fierce. In this highly competitive situation, it is important for companies to differentiate themselves if they are going to have a chance at success. And the competition to create the best solution method possible is higher than ever. Increased competition is forcing companies to lower costs and improve efficiency. A supply chain management(SCM) has become one of the most important solution methods of competitive advantage. This study has developed a simulator for the supply chain network problem. The simulator is designed to simulate the conditions of an actual supply chain network considering uncertainties. The simulator developed using commercial simulation tool ARENA and the results of computational experiments for a simple example were given and discussed to validate the developed simulator. Further research is needed, but using the simulator could become a useful tool for decision making in the supply chain network area.

Information Literacy (IL) is considered as an important aspect of everybody's life. In today's information society possessing IL skills is more significant than ever as information is available in many forms and formats. Schools are the primary places where these skills are imbibed in students. Organizations like UNESCO, IFLA, ALA, AASL, & ACRL have formulated IL Standards and Guidelines/Models at the international arena. Though the Government of India is making efforts in providing information literacy skills yet there are no set of standards/guidelines devised by any agency/organization at the school level. This paper gives a brief account of IL initiatives and highlights the trends and developments of IL programmes in Indian School Libraries. It recommends the nation to form a national level advisory committee to develop IL framework for Indian school Libraries. Further, it suggests that librarians should work in close collaboration with teachers for better results. A moderate attempt has been made to provide feasible solutions for effective implementation of IL programmes in school libraries.
