Personalization is user oriented dynamic method based on user preferences for easy access to what users want to view or get. It has become more important in mobile domain with rapid growth of wireless Internet and mobile phone market after success of web based market and therefore, it can be applied to service of spatial analysis result. In this paper, spatial analysis using user profile and notification service methods are proposed as one of personalized spatial data service methods for mobile users. A service system for spatial analysis with user profile is designed to prove possibility of spatial analysis based on user preferences and notification service is also designedto show generated output can be sent to user's mobile devices efficiently to make users informed of preferred information. Prototype system is implemented and it is applied to real estate data that has many selectable conditions by users. Information service based on user preferences can be applied to spatial data by using proposed system and it is efficient when cache module is used to shorten response time. Various user models for application domains and performance evaluation methods need to be developed in the future.

This study was planned for an empirical review of foodservice operation in expressway rest areas for a menu strategy targeting staff and customers. The results were as follows. Main foodservice category included 10-30 items of Korean dishes. The needs for having branded foodservice menu in rest areas were high in fusion/fast foods, snack/ready-made and beverages. Employment of professional cooks in rest areas was low (10-30%), and the most important factor was 'taste' when cooking Korean foods. Foreigners preferred fusion/fast foods and snack/ready-made foods to Korean food, beverages and Japanese/Chinese foods, and most of the foreigners ordered food with 'no question'(55.5%) or 'some questions'(34.8%). Rest area staff prepared some photos/pictures of foods (80-100%) for menu comprehension, but the accuracy of menu transcription was very low. Customers used a rest area once or twice, stayed for 10-20 min(43.6%)/20-30 min(38.6%), visited by car(77.7%) to relax and use toilets(61.6%) on average. Favorite food and snacks were Korean(32.7%) and ready made/snacks(33.0%), and they spent 5,000-10,000 won(51.3%), 3,000-5,000 won(25.8%) on them. Customer satisfaction with rest areas was 'average' regardless of gender, age, education levels and jobs. With this analysis, we should prepare an efficient menu strategy for customer satisfaction and plans for analyzing problems along with alternatives.

유효경쟁시장은 사업자의 수와 시장구조 측면에서는 독과점적인 시장이더라도 기존사업자간 경쟁이 상당히 치열하거나 잠재적 진입에 의한 경쟁압력이 커서 특정사업자가 시장지배력을 보유하거나 이를 행사하기 어려운 시장상태를 말하며, 항공산업의 경우 일반적인 네트워크 산업과 마찬가지로 대규모 설비투자가 필요하고 높은 고정비용과 규모의 경제가 뚜렷한 특성을 갖고 있으며 네트워크효과도 강하게 나타나 비대칭적 규제가 필요한 대표적인 산업이라고 할 수 있다. 우리나라 경제당국은 평균비용이 장기적으로 하락하는 대규모 자본산업에서 자연독점이 발생할 경우, 그 피해는 자연히 소비자에게 돌아 갈 것이며, 미국과 EC의 경쟁법상의 유효경쟁의 개념으로 제시되고 있는 요소들을 보면 주로 어느 한 기업이 시장지배력을 행사하는 시장상황을 나열하여 규제함으로써 최대의 이익이 소비자에게 돌아가도록 규제하고 있다. 항공운송사업은 자본집약적 서비스산업으로 일반서비스 산업에 비해 상대적으로 일정수준까지 자본투자가 전제되어야 하는 자본집약적 특성을 지닌다. 따라서 항공운송산업의 성패는 대규모 자본을 통한 운송능력에 대한 효율화 정도에 따라 결정된다. 여기에 시장에 진입 시기와 독점 유지기간도 중요한 역할을 한다. 또한 항공운송산업은 정부의 면허사업으로 선발항공사가 수익노선을 선점하여 운항할 경우, 정부의 별도 허가에 의하여 복수취항이 이루어진다고 하더라도 운항편수 및 고객 선호 시간대를 미리 선점할 수가 있어 후발항공사에 비해 우월적 지위를 갖게 되어 공정경쟁이 극히 어렵다고 할 수 있는데, 이는 수십년간 아시아나의 압도적인 서비스/안전에 대한 높은 평가에도 불구 대한항공과 아시아나의 격차는 2000년 이후 일정하게 유지되고 있다는 점에서 확인할 수 있다. 국내 항공운송산업은 면허산업으로, 운수권의 확보에 따라 항공사의 매출 차이가 결정되는 바, 항공운송산업에서의 유효경쟁을 확보는 1차적으로는 정부의 운수권 배분을 통하여 실현되며 양사의 운수권 배분내역에 의하면 선발사업자에 대한 유효경쟁정책이 실현되지 않고 있다고 할 수 있다. 대부분의 노선에서 복수취항이 허용된다고 하더라도 강력한 스케줄, 가격(운임) 경쟁력, 선발항공사의 이점, 고객 선호도의 미반영 등으로 인하여 공정한 경쟁이 이루어지지 않을 가능성이 매우 높다. 이처럼 평균비용이 장기적으로 하락하는 항공산업에서 선발항공사에 대한 쏠림 현상이 가중된다면 향후 10년내에 국내 항공운송산업에 자연 독점이 발생할 가능성은 매우 크며 그 피해는 소비자에게 돌아갈 것이 자명하다. 결국 우리나라의 항공운수산업에서의 유효경쟁환경을 조성하기 위해서는 운수권 배분 절차에서의 비대칭규제의 원리가 상당기간 적용되어야 하며, 복수취항이 허용된 노선에서도 후발사업자가 공정하게 경쟁할 수 있도록 비대칭규제방안이 강구되어야 한다. 뿐만아니라 보충적으로 공정거래법상의 시장지배적 지위의 남용규제와 같은 비대칭규제도 강력하게 집행되어야 할 것으로 판단된다.

Pharmaceutists are interested in drugstores which are selling, the sundries, cosmetics, medical devices, with drugs. Because drug stores without prescription issued by doctor have faced on finacial difficulties since speciality between doctors and pharmaceutists set us law. There are two types of drugstore which is a type of common drugstore, other is a type of traditional drugstore based on pharmaceuties in steady of big size of store based on studies, cosmetics and so on. Expansion of business for drugstore show us that most of customer are who are very sensitive in circumstance. Since 2,000 it has been expanded to large scale, so market analysts expect that volume of market will be increased to 10 times within 5 years. Drugstores have several kinds of merchandises which customers can take a choice for their demands, so most of customers the young generations. However, market customers will be changed to medium, and old generations as drugstores set freely. Furthermore everybody will enjoy in at drugstores effectively this reports that include of counter based on proposals and validities. This study show examples that have been executed successfully by the advanced countries, moreover big companies in domestic market have been expanding their market share for drugstore business. Through out change of circumstance surrounding drugstores, this report indicate how to induce the large drugstore with validities and trends. Since speciality of pharmaceutists and doctors executed, direction and a forecast of developing drugstores under change of distribution of them and may be suggested. I hope that this research will be helpful of interesting in drugstores, and also lot of distributors focuses on drugstores to develop the drugstores in future.

The traditional retail industry significantly changed over the past decade due to the mobile and online technologies. This change has been accompanied by a shift in consumer behavior regarding purchasing patterns. Despite the rise of online shopping, there are still specific categories of products, such as "Processed food" in Mongolia, for which traditional shopping remains the preferred purchase method. To prepare for the inevitable future of retail businesses, firms need to closely analyze the performance of their offline stores to plan their further actions in a new multi-channel environment. Retailers must integrate diverse channels into their operations to stay relevant and adjust to the shifting market. In this research, we have analyzed the performance data such as sales, profit, and amount of sales of offline stores by using clustering approach. From the clustering, we have found the several distinct insights by comparing the circumstances and performance of retail stores. For the certain retail stores, we have proposed three different strategies: a fulfillment hub store between online and offline channels, an experience store to elongate customers' time on the premises, and a merge between two non-related channels that could complement each other to increase traffic based on the store characteristics. With the proposed strategies, it may enhance the user experience and profit at the same time.

Companies have been making considerable efforts to develop innovative products for better competitiveness in the market, however, the education curriculum for innovative product development (IPD) in domestic universities needs has not been well developed. The present study was intended to identify the needs of students and practitioners regarding teaching subjects, pedagogical methods, and industry-academia collaboration that can be reflected in the development of IPD education curriculum. Through a literature survey 46 IPD teaching subjects of 7 categories (planning, feasibility analysis, concept development, product design, manufacturing process design, production, and ethics & law) were selected. Opinions on the preferences and importances of the teaching subjects, pedagogical methods, and industry-academia collaboration were collected from 53 college students who took courses of product development and 36 practitioners working in product development. While the students preferred the balanced teaching of all the subject categories, the practitioners suggested planning and concept development be taught with high importance; 6 subjects (product development strategy, customer needs identification, market research, concept generation method, design ideation method, and ergonomic design) received high ratings of preference and importance. The students preferred the mix of various pedagogical methods (lecture, discussion, presentation, practice, and case study) and provided needs on each pedagogical method. Lastly, the students wanted an opportunity of learning through industry-academia collaboration and the practitioners provided ideas for mutual benefits between industry and academia. The needs of students and practitioners identified in the study can be effectively applied to develop a better IPD education curriculum.

Today, many firms face the environment of high uncertainty and severe competition due to the rapid technology development and the diverse needs of customers. In the business environment, one of the most important ways to gain sustainable competitive advantage and future growth engine is related to NPD (New Product Development), which is a very important issue for practice and academia. Thus, this study intends to provide new values to practitioners and researchers related to NPD by analyzing current research trends and future trends in NPD field. For this, we bibliometrically analyzed keyword networks which consist of keywords that were already published in the eminent journals from Scopus database to generate insights that have not been captured in the previous reviews on the topic. As a result, we could understand the extant research streams in NPD field, and suggest the changes of specific research topics based on the connected relationships among keywords over the time. In addition, we also foresaw the general future research trends in NPD field based on the keywords according to preferential attachment processes. Through this study, it was confirmed that NPD keyword network is a small world network that follows the distribution of power law and the growth of network is formed by link formation by keyword preferential attachment. In addition, through component analysis and centrality analysis, keywords such as Innovation, New product innovation, Risk management, Concurrent engineering, Research and development, and Product life cycle management are highly centralized in NPD keyword network. On the other hand, as a result of examining the change of preferential attachment of keywords over the time, we suggested the required new research direction including i) NPD collaboration with suppliers, ii) NPD considering market uncertainty, iii) NPD considering convergence with the other academic areas like technology management and knowledge management, iv) NPD from SME(Small and medium enterprises) perspective. The results of this study can be used to determine the research trends of NPD and the new research themes for interdisciplinary studies with other disciplines.

In this paper, we investigate several factors that affect the locational decision of discount stores by using previous studies on the marketing area and the location of commercial facilities. We selected 21 primary variables that are expected to influence the decision of store location and, by factor analysis, grouped them into five underlying factors. Among these, the demographic factor, which shows the potential purchasing power level, had the greatest impact on the locational decision for the store. However, we found individual stores positioned according to unique locational characteristics in addition to the demographic factor. It means that we have to additionally consider if the vicinity of the market is based on any physical properties. Many previous studies proposed four decision factors for store location: the economic factor, the demographic factor, the land utilization factor, and traffic factor. However, the fivefold factors-our distinctive contribution-are more concrete and persuasive according to Korean reality. We show that location preference is based on the following criteria: (1) the area is densely populated, (2) houses stand close together, (3) residents have a high income level, (4) road traffic is developed and easy to access, and (5) public transportation is well developed. The demographic factor has the greatest impact on the location of a discount store. The number of households has a greater relevance to the demographic factor than does the individual consumer. Second, discount stores relatively prefer places where houses are located close together because such places offer easy access to the market. Third, a place whose residents have a high income level will be preferred, with its large cars and excellent traffic conditions. Fourth, a location would be highly rated if the roads around commercial facilities are well developed and their accessibility is good. Finally, discount stores must be located close to bus stops because female consumers, including housewives-the most important customers-evaluate stores based on distance. In this research, the variable of consumer attitude and preference was excluded, and the location factors of discount stores were analyzed according to a microscopic view through physical spatial data. In the future, the opening of new discount stores based on the five factors indicated above will require a comparatively shorter time from the first project feasibility analysis. In addition, the result of our study can be applied to the field of public policy for constructing and attracting large-scale distribution facilities.
