This study analyzes appropriate government policy frameworks for promoting IPTV industry by studying the way of adoption and diffusion of IPTV services. Until recently, most researches on government policies for technology adoption have focused on the personal context. This research adopts two theories, i.e., innovation characteristics theory for personal context and implementation process theory for organizational context. It also hypothesizes that the innovation characteristics more influence on the behavioral intention for usage new media in the level of personal innovativeness is high. Moreover, in the level of expectancy for diffusion policy is high, the implementation of IPTV services more influences on the behavioral intention. The results by statistical analysis, it is found that the higher the level of personal innovativeness is, and the higher the level of expectancy for diffusion policy is, the more behavioral intention will be influenced by the characteristics of innovation and implementation of IPTV service. Thus it is important for government agencies to find the way to facilitate personal innovativeness as well as expectancy for diffusion policy.

본 연구는 키넥트를 통해 사람의 걸음걸이를 측정하고 의사결정트리(Decision Tree)를 통해 분석함으로써 현재의 걸음걸이를 통해 측정자의 허리 또는 무릎에서 발생할 가능성이 높은 문제 또는 질병들을 예측하고 해당결과를 측정자에게 알린다. 본 연구를 진행하며 첫 번째 단계에서는 관련 논문이나 병원 자료 결과들을 통해 판별할 속성들을 정하였다. 두 번째 단계에서는 키넥트를 통해 측정한 실제 데이터를 적용하기에 앞서 첫 번째 단계에서 정한 속성들이 측정자의 문제 또는 질병들을 판단해내는 연관 정도가 높은지 테스트 데이터를 이용하였고 의사결정나무를 통해 분석하였다. 그 결과 7개의 속성 중 6개로 약 85.7%정도의 연관이 있었다. 마지막 세 번째 단계에서는 판별식을 세우고 실제 데이터들을 쌓아나가며 69명의 측정한 데이터를 분석한 결과 6개의 속성 중 5개의 속성이 허리와 연관정도가 높았고 이는 두 번째 단계에서 나왔던 결과인 약85.7%에 가까운 약83%의 결과가 도출되었다. 이를 기반으로 시스템을 개발해 나가며 판별 정확도를 향상시키기 위해 계속 측정해 데이터를 쌓아가고 관련된 식들의 문제점을 보완하며 또한 어떤 환경에서 키넥트의 측정값의 정확도가 올라가는지 연구할 예정이다.

The purpose of this study is to develop effective destination management strategies for three typical tourist destinations in Kangwon province based on the importance-performance analysis. The results show that overall performance levels of 21 management attributes in three destinations is relatively low, compared to the importance levels of the attributes. 6 attributes place in Concentrate Here, 4 attributes in Possible Overkill, 6 attributes in Keep Up Good Work, and 5 attributes in Low Priority. There is no significant difference in the importance level among three destinations, while performance levels are the lowest at Naksan & Kyungpo beaches, and highest at Ganhyun area. Findings of the survey expect to be used as fundamentals in management policy making process for each destinations.

Domestic coffee franchise market in South Korea has been rapidly growing along with developing the global coffee franchises as well as entering domestic franchise companies into the beverage market. Competitions in the markets are getting more accelerated and local franchises and owner-operated coffee shops are losing their market shares gradually as a result. Local franchises and owner-operated coffee shops in Daegu, however, are notable in that they are maintaining the competitiveness in the markets. This is a unique phenomenon, which deserves to be analyzed to identify the successful attributes as a case study. Important Performance Analysis (IPA) method has been employed for analyzing and its gap(i.e., difference between importance and performance) analysis shows that the price and quantity of coffee are the most important differentiating attributes of local and owner-operated coffee franchises in Daegu.

This study conducted an analysis using IPA metrics targeting college students to get strategic implications for marketing in the recently fast-growing mobile shopping market. The IPA analysis result about the selection of mobile shopping malls is as follows. First, out of the 21 features, 'reliability of the offered products(6.09)' had the highest level of importance and 'convenience of payment(5.29)' had the highest level of performance. Second, in the area of 'Doing great, Keep it up' 11 features were included such as 'convenience of payment' and 'reliability of the offered products'. Third, the feature that needed to be corrected in the area of 'Focus here' was 'shortening the waiting time for exchange, refund or warranty service'. Fourth, low priority areas in terms of importance and performance, there were 3 features including 'push/notification helps purchases'. Fifth, to the area of 'overdone' 4 features belonged such as 'variety in the type of products'.

Now, plastic surgery has become the industry for beauty. In order to know the characteristics of high-visit web sites that many people have visited, 33 high visit websites of plastic surgery were compared to 60 benchmark sites of same industry. We selected 34 web site attributes that can be measured objectively from existing studies. For analysis, Multiple Discriminant Analysis(MDA) is conducted for searching what attributes divide two group definitely. The result of this study shows the dividing attributes fall into 2 categories like 'Community', 'Up to date'. Thus, we are able to conclude that high-visit plastic surgery web sites are community-centric site but not contents-centric and are maintained with tide up to date. The methodology employed in this study provides an efficient way of improving satisfaction of visitors of plastic surgery website.
