길진호,신민수,김성철 에스케이텔레콤 (주) 2012 Telecommunications Review Vol.22 No.6

기술 발달로 인한 컨버전스의 급속한 진전과 스마트 기기 등이 등장하면서 기존 정보통신산업의 각 주체들간에 벌어지는 경쟁이 새로운 방향으로 진행되고 있다. 가치사슬의 변화와 주체들이 다양하게 분화되어 기존의 비즈니스 모델이 해체되면서, 해외의 선도 기업들이 주도하는 생태계에 국내 기업들이 끌려가고 있는 상황이다. 생태계 관점에서 참여 사업자들 사이의 경쟁력 연계는 생태계의 경쟁력 강화로 귀결된다. 국내 정보통신산업 생태계의 경쟁력 향상을 위해서는 각 생태계 참여자간 다양한 형태의 협력과 경쟁을 기반으로 발생되는 공진화가 필요하다. 이에 본 연구에서는 ANP분석을 통하여 산업내 각 참여자들간 협력행위의 우선순위를 도출하고,이를 바탕으로 참여자간 전략적 협력 모델 구조를 제시하고자 한다.

A Study on Calculating the Fee Range of Broadcasting Contents : Focus on IPTV

신민수,길진호,배성훈 한국데이터전략학회 2015 Journal of information technology applications & m Vol.22 No.2

Concerns have been growing about whether domestic internet protocol television (IPTV) can establish a solid foothold in the pay TV market, largely because of the lack of IPTV-only content and service differentiation. It has been difficult for IPTV providers to attract valuable PPs (program providers) to strengthen their positions, and IPTV providers have invested much money into procuring content. To survive this difficult situation, IPTV providers need to reappraise their profit sharing methods and content distribution structure to facilitate the expansion of their subscriber base. This can be done by attracting valuable PPs to IPTV providers and securing extra revenue by distributing more content for their PP partners. The IPTV industry has a different structure and value chain from the digital cable industry. Moreover, profit sharing schemes among participants in the IPTV industry are complicated. Thus it is essential to analyze the criteria for profit sharing, the selection of attributes in profit sharing, and their cause-effect relationship in developing fair pricing for broadcast content in the IPTV industry. This study introduces the attributes that need to be considered for the pricing of content and profit sharing among IPTV providers and PPs. In addition, this study uses system dynamics to analyze the relationship among those attributes along with additional associated factors for the pricing of content.

The aim of this work was to enhance the water vapor permeability of bio-polyurethane thin film, whose essential application is as a non-microporous type of film in breathable fabrics, by hybridizing it with nano- and micro-sized titania ($TiO_2$). The bio-polyurethanes were synthesized from 4,4-diphenylmethane diisocyanate (MDI) and a polyol mixture containing polyethylene glycol (PEG) and soybean oil-based polyol, that is, bio-glycols by the hydroxylation of soybean oils upto 25% by weight of bio-polyurethane. We studied the effect of hybridizing the bio-polyurethane films with hydrophilic nano- or micro-sized $TiO_2$ on their breathability by measuring the water contact angle and the water vapor permeability of the films; it was found to significantly enhance the permeability of the bio-polyurethane film. Further, nano-$TiO_2$ was more effective than micro-$TiO_2$ due to the higher surface area resulting from nano particles. On the other hand, it is expected that it would be possible to provide additive functionality to the bio-PU membranes due to photocatalytic effect of nano-$TiO_2$.

ERP시스템 사용성과 결정요인에 관한 연구

곽기영(Kee Young Kwahk),길진호(Jin Ho Kil) 한국경영학회 2010 經營學硏究 Vol.39 No.2

Turbulent changes of competitive environment have forced organizations to continue enhancing their capabilities to respond to the dynamic environment. With the competitive pressure and the development of information and communication technology (ICT), many organizations have introduced various kinds of enterprise-wide systems like enterprise resource planning (ERP) systems as strategic tools for the purpose of improving organizational performance. Despite their promised strategic benefits, however, their implementation has suffered from a high failure rate and difficulty in realizing the anticipated benefits. Many factors have been widely reported to account for the success and failure of ERP systems implementation, which are not limited to technical issues but various causes arising from the interactions among people, task, and technology. Previous studies have indicated that one of the most critical failure reasons is the lack of knowledge sharing and utilization across organizations. Individuals need to share and transfer their knowledge in order to attain successful usage of and performance benefits from ERP systems, while organizations have to focus on integration of existing knowledge with new one from ERP systems in order to achieve successful organizational change. As a consequence, many information systems (IS) researchers have paid attention to examining the effect of absorptive capacity closely associated with knowledge sharing and transferring on IS usage performance. Knowledge sharing and absorptive capacity can be interpreted in the context of social exchange, in which individuals anticipate future rewards without explicit promise in exchange for their contributions. Based on the social exchange, organizational citizenship behavior (OCB) can be described as a set of behaviors resulting from communications and interactions among individuals that help their colleagues spontaneously, comply with the rules and policy of organizations, prevent possible problems related to their tasks, and commit themselves to working for organizations. ERP systems implementation involves changes not only in systems but also in processes and other social dimensions, which requires appropriate communications and interactions among organizational members. A lack of communications and interactions due to a lack of OCB might lead to weak absorptive capacity and thus negatively influence knowledge sharing across organizations, because OCB facilitates a successful collaboration among functional units and positively impacts individual’s attitude toward radical organizational change. In addition, this kind of spontaneous activities of individuals facilitates enhancing their learning capabilities about the new knowledge and thereby positively influences knowledge sharing across organizations. With this motivation, this study has two research objectives. First, it introduces and tests a theoretical model accounting for the relationships among performance of ERP system usage, absorptive capacity, and OCB. Second, it examines a mediating role of absorptive capacity between OCB and performance of EPR system usage. In order to test the proposed model, the overall approach employed was a field study using the structural equation model. We developed our data collection instrument by adopting existing validated questions wherever possible. A total of 168 complete and valid responses were obtained from 15 organizations. We carried out data analysis using a twostep methodology with LISREL 8.7. The empirical results supported the proposed model and identified the role of the full mediation of absorptive capacity. As a result of the analysis, the following conclusions were reached. First, organizational citizenship behavior significantly influences absorptive capacity. Second, it was revealed that the absorptive capacity of the members of an organization significantly influences the usage performance of ERP systems. Third, absorptive capacity was found to
