This study is the first step for ICT-based service model development for exhibition service innovation. To obtain the goal of this research, we derived the core problems of current exhibition industry service through previous literature, open-ended question and focus group interview. And then, we provided prioritization of twelve new services utilizing six assessment items(importance, duplication, urgency, ease of execution, prevalence, publicness) to derive policy priorities. We analyzed two portfolios that combination of four assessment items - importance/urgency and ease of execution/prevalence. Through surveying and analyzing the result, this paper serves that the priority facts are 'The work invisible barrier installation services', 'Exhibition history management and referral services', and 'Exhibit labels and descriptive text information service utilizing Augmented Reality'. In particular, 'The work invisible barrier installation services' is the most important service not only the assessment criterion of duplication and publicness but also overall measurement score points.

Specialty stores, which have been major channels of Korean cosmetic industry, are bringing out a lot of problems in current distribution channel systems because of its repeated depression of sales. Especially, inefficiency in distribution channel systems is caused by cannibalistic price-off competition between specialty stores, too many launchings of new products, excessive sales promotion, absence or surplus of stock, and so on. Using qualitative methods such as in-depth interview and group discussion, the authors attempt In diagnose fundamental problems of the cosmetic specialty store distribution channels in three viewpoints； achievement of goals, marketing flows in channels, and relationship management. In addition, this paper suggests core strategies for building up the competitiveness of both of the maker and the retailer, The competitive strategies are mainly about securing profitability of retailers, smoothening of marketing flows in channels, and building-up trustful relationships between distribution channel members.

This paper analyzes the effects of population aging on regional differentiation from the New Economic Geography perspective. The addition of old-age population variable affects the price index, income, nominal wage, and real wage derived in the short-run equilibrium. Using the new model, we can better explain industrial agglomeration patterns corresponding to the new long-run equilibrium. As the real wage criterion does not properly take the old-age group into account, we employ the indirect utility function as an additional condition for equilibrium. We further consider tax as a policy tool for achieving a better long-run equilibrium. This would enable the government to direct the economy toward a particular equilibrium desired in the face of population aging.

Purpose: The salesperson, the core of the operating activities, plays the role of connecting the inside and outside of the company, representing the company to the consumer and identifying and responding to the customer's needs. The department store industry is the most representative retail industry in South Korea, and competition among its peer group and industry is intensifying, requiring differentiated service sales activities and performance from its employees. This study divided the sales force system into activity control(process-oriented control) and output control(performance-oriented control) and verified the differential impact on the job attitude of the salesperson (e.g., job satisfaction and burn-out), respectively. In addition, the effect of job satisfaction and burn-out of the salesperson on the job performance were checked. Research design, data, and methodology: The survey was conducted on 200 sales people working at five branch stores of Hyundai department store in Seoul, and 194 of them were analyzed. The reliability and validity of the variables were analyzed and hypotheses were verified through the SEM. Results: Results have shown that activity control has a greater impact on burn-out compared to output control, and output control has a greater impact on job satisfaction compared to activity control. It has been shown that the salesperson's burn-out does not affect sales performance, but that job satisfaction has a positive effect on sales performance. Conclusions: This study examines the effect of sales force management system such as activity control and output control, on the job attitude and sales performance in department stores. According to the results of this research, each of two control systems have a discriminatory effect on the job attitude variables. For the sales managers of department store, it is recommended to increase the efficiency of sales management by increasing the use of outcome control compared to activity control.

The purpose of this study was to analyze future student competency based elementary Korean language classes to examine how they can be combined with current classes based on achievement criterion. Focus Group Interviews (FGI) were conducted with elementary teachers to find current lesson plans and design strategies, and to analyze their perception of future student competency proposed by Ministry of Education. After competency based lesson design was combined with regular class and implemented, teachers were finally interviewed for feedback of the classes. This study found problem issues such as conception of core competencies, gap between student achievement and competency accomplishment, student evaluation system as well as administrative support for execution. This study concluded that teacher training and systematic support should be enforced to ensure teachers competencies before demanding strategically.

Indoor air quality (IAQ) is recognized as a byproduct of industrialization that took place in the 20th century. The great attention to IAQ has been gained since 1980s, and led to numerous research studies that have mainly made in the developed countries. As the development of residential environment in Korea enters in the process of qualitative growth, IAQ has viewed as one of the core issues in the society, and research in relation to IAQ has been implemented until now in the fields of engineering and medical science. It is widely known that the sources and effects of indoor air pollution have been various, and IAQ research with multidisciplinary approaches is required. Nevertheless, few research embedded into a socio-behavioral approach to identifying interventive measures of residents and analyzing their choices is made. The purpose of this study is to examine the use of an interactive measure of residents in apartments that is air purification with phytoncide available in the market, and to investigate their self-reported effects of the air purifying substance on sick building syndrome symptoms. This study utilizes a field experiment design with pre-test and post-test, and the experiment is conducted in a natural field setting. A total of 87 test subjects from 32 households with already sick building syndrome are drawn via internet, and the participation is solely voluntary. The participants receive and use the air purifying substance, and are asked to use it continuously for two weeks and identify their self-reported symptoms of before- and after-use. The research findings indicate that air purification using phytoncide is effective to alleviate their symptoms in relation to sick building syndrome. Also it is noted that the participants report that the use of the air purification causes the positive impacts on their daily life. Further research is needed that compares the group with only humidifier and evaluates the mid-term and long-term use of the air purification and its effects.

In this paper, we propose a cache algorithm based on user's context for enterprise/urban smallcell environments. The smallcell caching method is to store mobile users' data traffic at a storage which is equipped in smallcell base station and it has an effect of reducing core networks traffic volume. In our algorithm, contrary to existing smallcell cache algorithms, the cache storage is equipped in a edge server by using a concept of the Mobile Edge Computing. In order to reflect user's characteristics, the edge server classifies users into several groups based on user's context. Also the edge server changes the storage size and the cache replacement frequency of each group to improve the cache efficiency. As the result of performance evaluation, the proposed algorithm can improve the cache hit ratio by about 11% and cache efficiency by about 5.5% compared to the existing cache algorithm.

The Xylariaceae Tul. & C. Tul is a family of sphaeriaceous genera with obscure but apparently common ancestry (Rogers, 1979), A central core of genera - Xylaria, Hypoxylon, Rosellinia, Poronia, Podosordaria, Hypocopra, Daldinia, Biscogniauxia, Kretzschmaria, Camillea, Penzigia - are obviously related, regardless of the fact that the generic limits are arguable (Rogers, 1979; Barr, 1990; Eriksson & Hawksworth, 1991; Laessoe, 1994). In general, the family Xylariaceae is primarily defined as a group of stromatic pyrenomycetes with unitunicate asci characterized by a typical apical apparatus and pigmented ascospores having a germ slit (Rogers, 1979). Since Winter (1887) circumscribed the family to include Pyrenomycetes with predominately a dark stroma, dark unveiled spores containing 5 genera: Nummularia Tul. & C. Tul., Hypoxylon Bull., Ustulina Tul. & C.Tul., Poronia Willd. and XylariaHill ex Schrank, many more genera has been added to the family (Dennis, 1961; Eriksson & Hawksworth, 1993; Whalley, 1996). In the absence of a clear circumscription of the family (Rogers, 1994) the agreed number of accepted genera is governed by individual views and there are therefore difference between the proposals for the ascomycetes recognized 35 genera and indicated a further 3 which might belong there. Laessoe reviewed the family and included 37 genera but a few of these were listed as uncertain (Laessoe, 1994). In the most recent accounts Whalley (1996) listed 41 genera but again a number of these were considered uncertain and Ju and Rogers (1996) accepted 39 genera in their interpretation of the family. Since Laessoe (1994) merged Daldinia and Versiomyces with Hypoxylonand Ju and Rogers (1996) combined Astrocystis with Rosellinia and Helicogermslita, which can be argued strongly against, it is likely that a realistic number of genera will be close to 40 (Whalley, 1996; Table 1).
