모바일 어플리케이션 시장에서 업데이트는 (i) 어플리케이션의 가시성을 높이거나, (ii) 기존 사용자들의 충성도를 높이고 가치를 제고하거나, (iii) 기능 추가를 통해 시장을 확대하는 등 다양한 목적을 위한 전략적 마케팅 도구로 활용되고 있다. 많은 연구와 사례들은 이러한 업데이트가 모바일 어플리케이션 시장에서 생존하기 위해 중요하다는 점을 강조하고 있다. 그러나, 일부 다른 사례들은 업데이트가 오히려 사용자들의 반발과 이탈을 불러오기도 한다는 것을 보여주었다. 본 연구는 모바일 어플리케이션의 실제 사용량 데이터를 통해 어플리케이션의 이용 목적과 시장경쟁 환경에 따라 업데이트가 사용자들의 어플리케이션 이용패턴에 사용자수 측면에서, 이용빈도수 측면에서, 그리고 이용시간 측면에서 어떠한 영향을 주는지를 분석하였다.

The domestic food industry intends to expand overseas market. In order to succeed, in-depth research on local consumers is essential. This paper examined consumer research methodology and case studies based on sensory and consumer science for developing products targeting overseas market. Consumer research should be prece ded by overseas consumer panel construction. Then, this can be followed by application of various consumer research methodologies on new product development process. The most important consideration in this case is that application of same research methods or criteria as for domestic market could lead to significant errors in terms of reliability of results. Therefore, in order to develop successful products that accurately meet the needs of overseas consumers, careful study and consideration of the differences between markets would be essential from consumer researcher and decision-maker's sides.

This paper discusses the development of the educational simulator for the electricity spot market in korea. The interaction between lectures and users can be much enhanced via the web-based programs which result in the student's teaming effectiveness on an electricity spot market. However the difficulties for developing web-based application programs are that there can be the numerous unspecified users to access the application programs. To overcome the aforementioned multi-users problem and to develope the educational simulator, we have revised the system architecture, the modeling of application programs, and database which efficiently and effectively manages the complex data sets related to an electricity spot market. The developed application program is composed of the physical three tiers where the middle tier is logically divided into two kinds of application programs. The divided application programs are interconnected by using the Web-service based on XML (Extended Markup Technology) and HTTP (Hyper Text Transfer Protocol) which make it possible the distributed computing technology.

The objective of this study is to analyze the development trends of aerogel daily clothing through market research, and to discuss the main points of future aerogel application in daily clothing. Market research on daily clothing has been conducted by collecting relevant information on the internet and analyzing the content of the information. We summarized the market research results in three aspects: the daily clothing brand using aerogel, the aerogel composite used in daily clothing, and the property of aerogel daily clothing. From these results, it can be seen that the development of aerogel daily clothing is becoming active and specialized. But there are still many difficulties due to lack of development experience. One problem is that the application methods of aerogel composite in current aerogel daily clothing are similar. Another problem is that the analysis of consumer reviews can only provides a rough understanding of the property of aerogel daily clothing. Therefore, further application research of aerogel composite in the field of daily clothing through scientific evaluation is required. It is expected to improve the performance of the aerogel daily clothing and increase the utilization of aerogel composite by conducting the further application research.

At present, the Cournot model is one of the most commonly used theories to analyze the gaming situation in an oligopoly type market. However, several problems exist in the successful application of this model to the electricity market. The representative one is obtaining the inverse demand curve able to be induced from the relationship between market price and demand response. In the Cournot model, each player offers their generation quantity to obtain maximum profit, which is accomplished by reducing their quantity compared with available total capacity. As stated above, to obtain the probable Cournot equilibrium to reflect the real market situation, we have to induce the correct demand function first of all. Usually the correlation between price and demand appears over the long-term through statistical data analysis (for example, regression analysis) or by investigating consumer utility functions of several consumer groups classified as residential, industrial, and commercial. However, the elasticity has a tendency to change continuously according to the total market demand size or the level of market price. Therefore it should be updated as the trading period passes by. In this paper we propose a method for inducing and updating this price elasticity of demand function for more realistic market equilibrium.

IoT (Internet of Things) is a collective term referring to application services that provide information through sensors/devices connected to the internet. The real world application of IoT is expanding fast along with growing number of sensors/devices. However, since IoT application relies on vertical combination of sensors/devices networks, information sharing within IoT services remains unresolved challenge. Consequently, IoT sensors/devices demand high construction and maintenance costs, rendering the creation of new IoT services potentially expensive. One solution is to launch an IoT open market for information sharing similar to that of App Store for smart-phones. Doing so will efficiently allow novel IoT services to emerge across various industries, because developers can purchase licenses to access IoT resources directly via an open market. Sharing IoT resource information through an open market will create an echo-system conducive for easy utilization of resources and communication between IoT service providers, resource owners, and developers. This paper proposes the new business model of IoT open market for information sharing, and the requirements for ensuring security and standardization of open markets.

본 연구는 최근 전통시장의 디지털 전환의 시도로 진행되는 전통시장 배달 앱(application; app)의 성공요인을 파악하고자 시행되었다. 연구를 위해 전통시장 배달 앱의 성공요인을 앱의 시스템 특성, 배송 특성, 상품 특성, 고객 응대 특성의 4가지로 설정하고 운영성과와의 관계를 실증분석 하였다. 전통시장 배달 앱을 이용한 영업활동을 하고 있는 상인 148명을 대상으로 설문을 진행하였으며, 연구 결과 앱의 시스템 특성, 배송, 상품판매와 관련한 판촉활동은 운영성과에 정(+)의 영향을 미치는 것으로 나타났으며, 고객 응대와 관련해서는 유의한 결과를 얻지 못하였다. 이는 일부 배달 앱의 경우 고객의 리뷰를 확인하고 대응할 수 있는 메뉴가 탑재되어있지 않아 나타난 결과로 해석할 수 있다. 전통시장 배달 앱이 시행의 초기 단계이고 점진적으로 확대되어가는 현 상황에서 전통시장 배달 앱의 특성을 파악하고 운영성과에 미치는 영향을 분석하여 전통시장 배달 앱의 개발 지표를 만들고 디지털 전환을 통한 전통시장 활성화에 기여하는 데 본 연구의 시사점을 두고 있다.

The world mobile service is growing sharply and became bigger market than wired. So it is very needed to find the political way to promote mobile industry. The United States government recently decided to introduce new mobile policies for promoting mobile industry. Until now the telecommunications policies of the United States have affected policy developments for many countries including Korea. In this context, we studied the validity of introducing new mobile policies of the United States in Korea. We found that new mobile policies can cause the change of mobile market environment; mobile market power will be dispersed from network to content, application and devise, and new mobile market environment where consumers freely select and use network as well as content, application and devise will be made. Also we found empirically that if new policies are introduced in Korea, mobile industry will be promoted as Korean consumers use mobile services and goods quite actively in new mobile market. We think our results provide reasonable evidence to introduce new mobile policies in Korea.
