As intensifying competition alters the dynamics of the wireless industry and carriers begin to tap out traditional subscribers-business users and early adopters-wireless operators have come under pressure to begin expanding their target subscriber base. While alternative market segments such as youths, senior citizens, and lower-income or credit-challenged customers often offer less compelling fundamentals (i.e., lower average revenue per user and higher churn rates), carriers, in their race to increase market share, can no longer overlook these potential market segments. In particular, the youth market is a very appealing market segment for carriers to focus on for several reasons. Carriers in many parts of the world have already begun recognizing the compelling advantages of concentrating on youths and teens. This paper will examine the dynamics of the youth/teen population and what attributes make this group an appealing market for wireless carriers. In addition, it will take a look at new emerging technologies that may help carriers attract the youth market especially mobile data, entertainment applications, and wireless messaging. This paper also studies the sensation that carriers in Europe and Japan are achieving with the youth population and suggests how carriers in Korea can emulate that success.

While forecasting sales of a new product is very difficult, it is critical to market success. This is especially true when other products have a highly negative influence on the product because of competition effect. In this paper, we develop a choice-based competitive diffusion model and apply to the case where two digital mobile telecommunication services, that is, digital cellular and PCS services, compete. The basic premise is that demand patterns result from choice behavior, where customers choose a product to maximize their utility. In comparison with Bass-type competitive diffusion models, our model provides superior fitting and forecasting performance. The choice-based model is useful in that it enables the description of such competitive environments and provides the flexibility to include marketing mix variables such as price and advertising.

Chronic diseases as well as a growing population of older adults are currently the leading cause of ill health and economic burden worldwide. Managing those diseases in one-on-one medical consultations poses substantial challenges due to limited time and resources in the current health care system. Various approaches have been taken to manage these conditions, most with limited success. Shared medical appointments (SMAs) are an innovative care delivery option to make the testing of alternative care modalities a prime concern. SMAs are individual medical consultations carried out in a group of patients with similar diseases by providing education, medication management, and disease monitoring. SMAs, since their initial conceptualization in 1998, have gained much popularity and adopted as one of the standard processes in many countries. Accumulated evidence-based studies show outcomes for increasing access to care, behavioral change facilitated through self-management education, maintained/better outcomes, physician productivity, and enhanced resource management. This review summarizes current evidence regarding the existing status of SMAs abroad. An extensive literature search was conducted on major electronic databases including PubMed and Google Scholar. This study suggests to explore and exploit the SMAs which have unique potential as a healthcare delivery innovation in Korea.

The objective of this study was to verify the effects of brand equity of small & medium hospitals on trust and relationship commitment and mediation effect of trust in the relation between brand equity and relationship commitment. For testing reliability and validity of the measurement tool, Cronbach's ${\alpha}$ and confirmatory factor analysis was used, respectively. A structural equation model was applied for verifying the study model suggested. Out of 450 questionnaires distributed, 439 was returned. On the study results, brand image and perceived quality positively determined trust of customers for small & medium hospitals. Customers' trust also has a positive effect on relationship commitment. Brand awareness positively influence the levels of relationship commitment. Moreover, a mediation effect was identified. Customers' trust mediated the effects of brand image and perceived quality on relationship commitment of hospitals customers. On conclusions, relationship commitment was determined, either directly or indirectly, by brand image and perceived quality, while trust mediated the their relationship. Thus, hospitals management may use the concepts of brand equity and trust as a key success factor of their business purposes.

Designing effective navigation aids for customer interfaces is critical for the success of cyber shopping malls. Navigation aids can be classified into either basic ones which are based on the structure of the malls or add-ons which are not. Add-on navigation aids provide various short-cuts to promote efficient traversal in the cyber shopping malls, but too many of them would increase the complexity of the customer interface. Metaphors have been used widely for the design of add-on navigation aids, but little research evaluates their impact on the processes and outcomes of customers behavior in cyber shopping malls. This paper presents an empirical study that investigates the navigation process of customers and the subjective evaluation of their shopping experience. This research implemented two versions of a test-bed cyber shopping mall according to different metaphors used; one based on a spatial metaphor, and the other based on a non spatial metaphor. The results of the experiment indicate that navigation aids based on the spatial metaphor were used more frequently, which resulted in better understanding about the entire structure of the cyber shopping malls, which in turn led to an increased ease of finding target items and also a more pleasant shopping experience. The benefits of navigation aids based on the spatial metaphor became more evident when customers were looking for ad-hoc category items rather than common items. This paper presents plausible explanations for the results and implications to the design of navigation aids for cyber shopping malls.

The research aims to examine the impact of leadership style on accountants' commitment with FDI firms in Vietnam based on theory of Bass and Avolio (2004). A survey with 110 accountants in FDI firms was conducted. The total of 110 respondents with full information were used for data entry and analysis. Through quantity methodology, we used Cronbach's Alpha, EFA and correlation analysis to determine the relationship between leadership style and three dependent variables including affective, normative and continuance commitment. The results showed that the leadership style had positive relationships with accountants' commitments. In particular, normative commitment with FDI firms of accountants is the most strongest. In addition, there is no statistically difference in the level of three commitments with FDI firms of accountants for three groups of job description. From the findings, this study suggests several recommendations to improve accountants' commitments such as intellectually stimulating, individualized consideration, inspirational motivation, idealized influence, and idealized influence behavior. The results are considered as a useful reference for establishing policies to attract talent personnel toward to sustainable development of firms. Commitment with the organization is a crucial factor to gain a competitive advantage and guide the success of organizations by satisfying customers, maintaining productivity and efficiency.

디지털 시대를 맞아 21세기의 가장 주목받는 산업인 문화산업 중에서도 대표적인 게임산업은 최근 어느 때보다도 관심도가 높아지고 있다. 이러한 게임산업에 있어 게임 캐릭터의 역할은 시대에 따라 많은 변화를 가져왔고, 현재 게임 캐릭터는 게임 자체의 성공여부에도 많은 영향력을 미치고 있다. 초기의 게임 캐릭터는 단순히 게임만을 위한 캐릭터로, 캐릭터 자체의 의미는 거의 없었지만 게임산업이 점차 변화를 거듭하면서 게임의 내용과 시나리오 이상으로 게임 캐릭터의 중요성이 인식되기 시작되었다. 따라서 게임의 주인공이라 할 수 있는 캐릭터의 "조형성"은 제품 간에 차별 짓는 중요 요소로서, 게임의 작품성과 상품성을 높이는데 필수적인 요인으로 작용한다.

This paper examines critical successful elements related to the management of new product development process. For this, we have selected a VK-X100, slim bar type cellular phone, produced by VK mobile co., which was thought as a successful product development case and then analysed the case from a concept driven strategic product development's point of view. We have performed in-depth interviews with project managers, engineers and designers to get information on the product development process and analysed huge amount of data obtained from web-sites, global market indicators, and related firms' materials to find a changing trend of market conditions. The findings suggest that the successful new Product development and management is shaped by a number of different factors, such as the business environments, firm's technological level, firm's deep market insight capabilities, nature of the product development activities, and so on. Finally, we suggested the limitation of our research and further research subjects that would be required to support our findings.

인터넷을 기반으로 한 전자상거래의 등장은 상거래에 있어 지역적인 제한을 없애는 역할을 하고 있다. 이것은 상거래에 있어서 지금까지의 통념을 새롭게 정립해야 하는 것을 의미한다. 즉 촉각이 우선 되던 패턴에서 벗어나 시각이 우선 되는 것을 의미한다. 전자상거래 쇼핑몰의 성패여부가 이 시각을 붙잡아 놓는 것에 있다해도 과언은 아닐 것이다. 소비자의 다양한 욕구에 부응하고 이에 맞는 컨텐츠의 개발을 통한 쇼핑몰의 구축으로 물품구매까지 연결시킬 수 있어야 한다. 따라서, 본 논문에서는 쇼핑몰 구축에 있어 소비자의 욕구를 만족시키기 위한 유용한 컨텐츠의 활용에 대해 알아보고 그 효율성에 대해 연구하였다.
