IT융합제품 잠재구매자의 외부정보원천 활용에 대한 연구

유재흥(Jae-Heung Yoo),최새솔(Sae-Sol Choi),최문기(Mun-Kee Choi) 한국콘텐츠학회 2011 한국콘텐츠학회논문지 Vol.11 No.10

본 연구에서는 IT융합제품 구매 결정에 있어 잠재 구매자들이 어떻게 외부 정보를 활용하는지를 대표적 IT융합제품인 스마트폰 사례를 중심으로 살펴보고 있다. 외부 정보 원천 (external information)의 활용이 중요시 되는 이유는 스마트폰과 같은 신기술 기반의 융합제품이 더 이상 제품 사양만으로 차별화되는 탐색재가 아닌 사용자 인터페이스, 애플리케이션 이용 등으로부터 체득한 경험정보가 더욱 중요시되는 경험재적 성격을 포함하기 때문이다. 기존의 연구에서는 이러한 신기술 기반의 제품 선택에 있어 지인들이나 일반 소비자들의 구전이 중요한 역할을 하는 것을 검증하였으나 온라인, 오프라인을 통해 다양한 정보 원천의 영향력을 비교 검증하는 실증 연구는 거의 없었다. 본 연구에서는 기존 연구를 참조하여 외부 정보 원천을 기업광고, 지인집단, 전문가집단, 일반소비자집단, 언론매체로 구분하고 이러한 외부 정보 원천이 어떻게 스마트폰의 구매 결정에 영향을 미치는 지를 정보 원천의 속성, 정보의 품질인식 측면에서 실증 분석하였다. 특히, 잠재구매자의 자기조절초점(self-regulatory focus)에 따라 정보 원천에 대한 속성 인식과 각 정보 원천으로부터 발생한 정보에 대한 품질 평가에 차이가 존재함을 밝혔다. In this study, we have examined how the potential users of IT convergence product use the external information sources for purchasing decision focusing on a case of smartphone. Although the specifications and price of IT convergence products, such as smartphone, tablet pc, and smart TV, are considered as major criteria for purchasing decision, the competitiveness of these factors have disappeared as many companies launch similar products in the market. External information sources play a significant role to differentiate the alternatives by offering value-added experience information. The effect of external information sources becomes stronger for experience and high-involvement product whose performance can be evaluated through only users’ direct experience. In this study, we categorized the external information sources for smartphone into five; company ads, personal network, expert group, consumers, and media. Through an empirical study with potential smartphone users, we verified how these external information sources affect users’ purchasing decision in the perspective of the perceived attributes of information source, quality of information, and individual’s characteristics based on self-regulatory theory.

ATCA 기반 통신 장비의 수요 요인 분석 및 도입 전략에 관한 연구

유재흥,하임숙,최문기,Yoo Jae-heung,Ha Im-sook,Choi Mun-kee 한국통신학회 2005 韓國通信學會論文誌 Vol.30 No.7B

ATCA(Advanced Telecom Computing Architecture)는 장기간의 통신 장비 시장의 침체에 돌파구를 마련하기 위해 100여개의 관련 업계가 모여 만든 차세대 표준 네트워크 설계 규격이다. ATCA는 기존 소수의 대형 벤더들이 자사의 고유 시스템을 공급함으로써 발생했던 이기종간의 호환성 문제, 고가의 장비가격, 시스템 변경 및 확장에 있어 어려움, 수요자의 공급업체에 대한 기술 의존성과 같은 문제를 해결할 수 있을 것으로 기대되고 있다. 본 연구에서는 ATCA 기반 장비의 잠재 수요자인 기업의 입장에서 어떠한 요인들을 기준으로 시스템을 채택하는 지를 Rogers의 혁신 이론에 근거하여 살펴보고 있으며 91개 기업체를 대상으로 설문 조사를 실시하여 실증 분석하였다. 로지스틱 회귀분석을 통해 ATCA 장비 구매에 유의한 영향을 주는 요인을 기준으로 군집 분석을 실시하여 기업의 특성에 따른 ATCA 장비 도입 전략을 제시한다. This paper aims to find influencing factors for firms to adopt network equipments which based on Advanced Telecom Computing Architecture (ATCA). ATCA suggests a standardized specification for telecom equipments design. This new paradigm of developing network equipment provides benefits for network equipment manufacturers by reducing development time for new equipments with lower CapEx and OpEx. It also deliver oportunities for telecom services providers to exploit or test new services by replacing or upgrading part of total system with modular based network equipments. The research model basically depends on various researches based on Rogers' Innovation and Diffusion theory and it is verified through an empirical study for ninety-one domestic forms. Binary logistic regression was conducted to find the relationship between purchase intention and factors affecting new technology adoption. As a result, two factors such as scalability and cost/benefit effectiveness of the new system were statistically significant. Cluster analysis followed with those two variables. This helps TEMs (Telecom Equipments Manufacturers) get some implications on timing and target customers for diffusing the ATCA based technologies in the market.

공공SW의 新패러다임

유재흥(Yoo Jae Heung),김준연(Kim Jun Youn),강송희(Kang Song Hee) 한국IT서비스학회 2015 한국IT서비스학회 학술대회 논문집 Vol.2015 No.추계

지난 20년간 국내 공공SW는 정부주도형으로 추진되면서 2010년 이래 연속 UN전자정부 평가 1위를 차지하는 등 세계 최고 수준의 정보화 국가로 성장하는데 기여했다. 한편,이러한 성장 이면엔 공공SW시장에 참여하는 정부발주자와 기업간 제값주기, 부당하도급, 대중소동반성장 등의 문제가 끊임없이 제기되어 왔다. 더욱이, 정보화예산의 정체가 예상되는 가운데 공공정보화 사업도 성숙기를 지나고 있어 시장은 점점 활력을 잃고 있다. 본 연구는 이러한 공공SW시장의 고질적인 문제를 해결하고자 시도되었던 정부의 제도주의적 처방과 기업규모에 따른 기업역량론 중심의 최근 연구의 한계에서 벗어나 기술혁신론적 입장에서 공공SW생태계의 강건성(Robustness)을 우선적으로 회복할 수 있는 방안을 검토한다. 공공SW생태계 강건성은 기술변화에 대한 기업들의 적응력을 높이는데 기여하는 정도로 혁신역량을 확보한 기업들의 SW를 공공에서 수용할 수 있는 제도적 유연성이다. 이를 위해서는 현재 구축운영(SI)중심의 수발주 체계를 다양한 민관협력 및 계약 방식으로 다원화하는 노력이 필요하다. 이를 통해, 인건비 중심의 수주경쟁에서 기술역량 기반의 서비스경쟁 유도, 서비스수준협약(SLA)에 따른 공정한 계약 질서를 조성, 위계적 다단계 하도급 구조에서 수평적 동반성장의 협업관계로 생태계 기반을 재구축함으로써 공공SW시장의 제반 문제를 해결해야한다는 정책적 시사를 결론으로 제시하였다.

The convention industry is one of those industries that require the highest quality service both in professionalism and diversity among various service industries. In order to successfully conduct an international conference, the government concerned as well as business operators such as travel agencies, airliners, hotels, shopping centers and other tourism-related corporations should provide all kinds of services from beginning to the end of an international conference. Therefore, establishing a system among these service providers may be the foremost task to be fulfilled more than anything else. Boosted by the breath-taking economic growth and heightened national status in the international arena, Korea has extended international exchange on various fronts. And substantial development of basic industries for international conferences such as airline network, accommodations and conference facilities is keeping the number of international conferences held in Korea on the rise. The Seoul Government is showing much interest in the international conference industry as ASEM 2000 is just around the comer, and a few convention centers are under consideration to be built in Seoul and other major cities of Korea. Hopefully, holding ASEM 2000 will be a stepping stone on which Korea's international conference industry may develop further to be recognized as one of the best countries to convene an international conference later on. To that goal, both the public and private sectors would have to show more interest and do whatever necessary it may be. In addition, deeper and broader research on the international conference industry would have to be conducted.

Statement of problem: The endodontically treated tooth is generally restored with post and core, owing to the brittle and the loss of large amount of tooth structure. As periodontal treatment was developed, there are many cases that periodontally involved teeth used in prosthetic treatment. Purpose: The purpose of this study was to analyze the stress distribution in the dentin and post structures by the various post materials and the amount of remaining alveolar bone height. Material and method: The 3-dimensional finite element models of mandible 1st premolars were divided into six types according to the various amount of remaining alveolar bone and post type. All types were modeled using equal length, diameter and shape of the post. Three types of post and core materials were used: prefabricated titaniumpost and amalgam core, prefabricated stainless steel post and amalgam core, and cast gold post and core. 300 Newton force was applied to functional cusp of mandible 1st premolar. Results: The results were as follows: First, there was no apparent difference in the pattern of stress distribution according to the alveolar bone condition concentrate on the post middle area. Second, there was difference in pattern of stress distribution according to the core materials, gold post and core generated same than amalgam core. Third, there was no apparent difference in the pattern of stress distribution within the dentin according to the post and core materials. But a cast gold post and core generated the lowest maximum stress value, a stainless steel post generated the highest maximum stress value. Fourth, in the reduced alveolar bone model, maximum stress value is 1.5 times than that of the normal alveolar bone model. Conclusion: Within the limitations of this study, to provide minimal stress to the root with alveolar bone reduced, the post length may be as long as apical seal was not destroyed. To prevent fracture of tooth, it is rational to use gold alloy which material was good for stress distribution for post materials.
