Seungbong Park,Minkyo Seo 한국인터넷전자상거래학회 2015 인터넷전자상거래연구 Vol.15 No.2

There has been growing attention toward intangible resources as a source of competitive advantage. Due to the unique nature, organizations are concerned with enhancing ways of developing and managing intangible resources. Especially in the context of electronic commerce represented by intensive competition, it becomes increasingly important to understand the role of intangible resources which are inherently hard to identify. The objective of this study is to examine the role of intangible resources in generating potential benefits towards competitive advantage. For doing this, we suggest a framework for investigating the role of intangible resources and apply it to the B2C e-shop context to demonstrate a presented framework. Based on the insights from framework concepts and case findings, several propositions are derived for further related research.

A Conceptual Model of the Business Model Competency Assessment

Seungbong Park,Junseok Seo 한국인터넷전자상거래학회 2015 인터넷전자상거래연구 Vol.15 No.5

Recently, the development of new and emerging business models has opened many new business opportunities and changed the nature of competition in electronic commerce. With the current challenges of implementing business models, the importance of business model assessment has been widely recognized. Nevertheless, there is relatively little research towards evaluation of business model which allows the organizations to innovate their internal business process and exploit business opportunities. The objective of this paper is to provide a better understanding of how business model competencies can be monitored and evaluated. To investigate this, we conceptualize business model competency and develop a model of the business model competency assessment based on the work of Di Valentin et al.(2012), and test it in the Internet portal service contexts.

박승봉(Park Seungbong) 한국컴퓨터정보학회 2006 韓國컴퓨터情報學會論文誌 Vol.11 No.5

지식관리 전략은 비즈니스 기회의 창출과 유지에 핵심적인 요소로 인식되고 있다. 본 연구의 목적은 전자지급결제 영역에서의 지식관리의 역할을 지식공유 관점에서 분석하고, 다양한 전자지급결제방식에 적합한 지식공유 전략을 제시하는 것이다. 이를 위하여 전자지급결제의 특성을 결정짓는 2가지 요소인 신뢰성과 효율성을 기반으로 지식관리-전자지급결제 분류모형도를 제시하고, 각 영역에 적합한 지식공유 전략을 도출하였다. 연구의 결과에서 전자지급결제 특성과 지식공유 전략의 정합성이 전자지급결제 영역의 거래 당사자간의 관계 결속을 증가시키고 거래 과정을 최적화 시킬 수 있음을 제시하였다. Knowledge management strategy has become a one of the most important factors creating and maintaining the business opportunities. In this paper, I present a KM-ePAY typology to investigate the role of knowledge sharing strategy in the electronic payment domain. Specifically, I examine the characteristics of four types of electronic payment systems based on the confidence and efficiency that characterize the feature of electronic payment media and identify appropriate knowledge sharing approaches for each component. In conclusion, my findings indicate that knowledge sharing approaches which are align with the characteristics of electronic payment give a way both to increase relationship commitment and to optimize process over electronic payment transactions.

OBJECTIVES: Proper risk assessment is important for the primary prevention of atherosclerotic cardiovascular disease (ASCVD). However, no validated risk prediction tools are currently in use in Korea. This study sought to develop a 10-year risk prediction model for incident ASCVD. METHODS: Using the National Sample Cohort of Korea, 325,934 subjects aged 20-80 years without previous ASCVD were enrolled. ASCVD was defined as a composite of cardiovascular death, myocardial infarction, and stroke. The Korean atherosclerotic cardiovas cular disease risk prediction (K-CVD) model was developed separately for men and women using the development dataset and validated in the validation dataset. Furthermore, the model performance was compared with the Framingham risk score (FRS) and pooled cohort equation (PCE). RESULTS: Over 10 years of follow-up, 4,367 ASCVD events occurred in the overall population. The predictors of ASCVD included in the model were age, smoking status, diabetes, systolic blood pressure, lipid profiles, urine protein, and lipid-lowering and blood pressure-lowering treatment. The K-CVD model had good discrimination and strong calibration in the validation dataset (time-dependent area under the curve=0.846; 95% confidence interval, 0.828 to 0.864; calibration χ2=4.73, goodness-of-fit p=0.32). Compared with our model, both FRS and PCE showed worse calibration, overestimating ASCVD risk in the Korean population. CONCLUSIONS: Through a nationwide cohort, we developed a model for 10-year ASCVD risk prediction in a contemporary Korean population. The K-CVD model showed excellent discrimination and calibration in Koreans. This population-based risk prediction tool would help to appropriately identify high-risk individuals and provide preventive interventions in the Korean population.

진화론적 관점은 조직과 환경의 상호작용을 통하여 조직의 변화를 설명하고자하는 이론으로서, 자원기반관점의 한계를 보완할 수 있는 이론으로 주목받아왔다. 조직의 성과와 실패와 관련하여, 진화론적 관점에서 다양한 연구가 수행되어 오고 있으나, 연구 분야에 따라 그 개념적 정의와 응용이 다양하게 적용되어옴으로써 관련 연구의 확장에 많은 어려움이 있어왔다. 본 연구에서는 진화론적 관점에서 그동안 다양하게 설명되어온 상호작용의 개념들을 바탕으로 하여 전통적인 변이(variation)와 선택(selection)의 개념 외에 조직변화 과정에서 유지(retention)의 역할을 재규명하였다. 이를 통해 ‘변이-유지’, ‘선택-유지’라는 2가지 차원을 중심으로 진화론적 관점의 핵심인 조직과 환경의 4가지 상호작용을 설명하는 통합적 프레임워크를 제시하였다. 또한 이 상호작용 과정에서의 조직학습과 조직탐색의 역할을 규명함으로써 2가지 조직변화 모델을 제시하였다.

페이스북을 활용한 대학수업에서 상호의존성, 동료간 친밀성, 지각된 유용성이 학습태도와 학습만족도에 미치는 영향

본 연구는 페이스북의 교육적 활용에 대해 규명해 보고, 대학수업에서 학습자들간의 상호의존성, 동료 간 친밀성, 지각된 유용성이 학습태도 및 학습만족도에 어떠한 영향을 미치는지 검증하는데 목적을 두고 수행하였다. K대학에서 페이스북을 활 용한 대학수업에 참여한 학생 152명을 대상으로 설문조사를 실시하였다. 수집된 자료는 SAS 9.3을 사용하여 One-way MANOVA를 수행하였다. 본 연구의 결론은 다음과 같다. 첫째, 학습자의 상호의존성 수준에 따라 학습태도와 학습만족도에 유의미한 차이가 있는 것으로 밝혀졌으며, 긍정적 상호의존성이 학습태도와 학습만족도가 높은 것으로 나타났다. 둘째, 학습자들의 동료간 친밀성 수 준에 따라 학습태도와 학습만족도에 유의미한 차이가 있는 것으로 밝혀졌으며, 학습자 서로 간의 동료간 친밀성 수준이 높을수록 학습태도와 학습만족도가 높다고 해석할 수 있다. 셋째, 학습자의 지각된 유용성 수준에 따라 학습태도와 학습만족도에 유의미한 차이가 있는 것으로 밝혀졌으며, 높은 유용성 인식은 학습태도와 학습만족도 또한 높은 것으로 나타났다. The study purposes were to determine educational use of Facebook by university students and to identify whether interdependence among university students, familiarity of colleagues, perceived usefulness by students affect their learning attitude and satisfaction. In order to achieve these purposes, the researcher conducted literature review and survey with 152 university students in K university in Seoul. Survey instruments were developed by the researcher based on previous literature review. SAS version 9.3 was used to implement statistical analysis. Major statistical analyses were one-way MANOVA according to the independent variables such as interdependence, familiarity, and usefulness. The major study findings were as follows. First, interdependence was identified having influence both learning attitude and learning satisfaction according to the result of MANOVA. As level of interdependence is increase, students, learning attitude and satisfaction get higher. Second, it is also identified that familiarity significantly affected students’ learning attitude and satisfaction. Similarly, students learning attitude and satisfaction increase in accordance with level of familiarity. Third, perceived usefulness was related to students’ learning attitude and satisfaction. Like the above results, higher perceived usefulness results in more positive learning attitude and higher satisfaction. This study suggests that further research should focus on various variables such as collaboration with Facebook use.
