Gasoline prices vary across Korea. Some gas stations charge higher prices, while others charge lower prices. In this paper, we try to find: why gasoline prices differ markedly across regions. We empirically estimate the determinants of gas prices by incorporating supply side factors as well as demand side factors into the empirical model. Empirical results show that both location-specific factors and store-specific factors affect gas prices. Concentration of competing stores, store brands, ownership of gas stations, and self-service availability influence gas prices. In addition, the availability of other customer services such as convenience stores, car wash, and auto repairs affects gas prices.

This study analyzed the buying patterns of American and Korean female college students in terms of criteria for clothing selection； store preferences； criteria for store selection； fashion information sources； expressions of customer dissatisfaction； purchasing frequency and motivations for purchasing clothes. The study was implemented through self-administered questionnaires which were back translated for validity. The samples consisted of 730 female college students majoring in the fields related to clothing and textiles： 310 U.S. and 412 Korean students. Likert scales were used for most measures with 1＝never or very unimportant and 5＝always or very important. Data were analyzed by factor analysis, analysis of covariance, Duncans multiple comparison, and t-test. Results are as follows： 1) Design factor was the most important criteria in clothing selection with no differences between country groups. There were, however, significant differences for psychological exhibition factors, practical and economic factors. 2) Both groups preferred specialty and department stores, with department stores more popular in Korea. 3) Merchandise was the most important store selection criterion and fashion magazines and self-experience were rated as the most important information sources for the both groups. 4) Korean group expressed their dissatisfaction with and observable problem with a product before purchase more often than U.S. group, but the U.S. group was more vocal about color loss or shrinkage after care procedures. 5) Some clear differences between the two countries emerged. Marketers targeting American consumers should pay more attention to practicality and service； to Korean consumers more symbolic meaning of products.

This study focuses on the application of the PEM Fuel Cell(PEMFC) hybrid system, which includes a regenerative braking system with supercapacitor(SC) and battery. The purpose of this study is to evaluate the characteristics of regenerative energy and to propose solutions to increase regenerative energy via vehicle simulation. To achieve this target, we set the rated motor speed to 3,000/2,500/2,000 rpm. Because the flywheel is directly connected to the motor, the generator activates regenerative braking by using the rotational momentum of the flywheel when the flywheel reaches the set speed after the motor stops. We could then measure the characteristics of regenerative braking of voltage, current, power, energy change, etc. Meanwhile, we calculate the storage efficiency of the SC or the battery. Our results show that the SC stores 18% of the regenerative energy, while battery stores 15% of the energy. Since the regenerative energy decreases with the decrease of the motor rotating speed that 5,027 J and 2,915 J are restored at 3,000 and 2,500 rpm, respectively. The experimental results also prove that regenerative braking energy is able to be obtained if and only if the speed of flywheel is over 2,500 PRM, and the efficiency of the system can be further improved.

The Korean apparel manufacturing industry started to meet domestic demands which had depended on importation in 1950s, growing into one of the export-oriented industries with several Five-Year Economic Development Plans. In spite of the development, inefficient organization of distribution of apparel manufacturing industry which connects production with consumption impedes further development of the industry. This study aims at suggesting desirable distribution system of ladies' apparel, the core of the fashion industry. This researcher interviewed those who are concerned in twenty-eight ladies' apparel manufacturing compaines, analyzing the current state of distribution in the industry and the problems. The results are as follows; 1. Forty-five percent of ladies' apparel is distributed through department stores. Therefore, the department stores need to assume their roles in sales and try to improve the condition and to train professional buyers. 2. The sales network is concentrated on the five biggest cities such as Seoul, Pusan, Taegu, Taechon, and Kwangju, prompting the need to be diversified. 3, Tke existing distribution forms distribution systems have many irrational factors which are aggravnting the rate of goods in stock. 4. The manufacturing companies do not implement studies on distribution. The companies should try to establish clear concepts on production and distribution on their own for better planning skills. 5. Computerized systems need to manage the procedures ranging from ordering, distribution, sales to inventory.

본 연구는 소비자-기업간 관계마케팅모델을 개발하는 데 주된 목적을 갖고 있다. 본 연구모델은 소비자를 단순한 환경변수의 하나로 인식해왔던 기존 마케팅의 통합적 관점을 비판하고 소비자를 사업의 동반자로써 인식하는 소비자 중심의 관계마케팅 모델을 제안하였다. 소비자 중심의 관계모델은 소비자를 기업 이익의 원천으로 보는 통합적 관점이 아닌, 소비자를 사업관계의 동반자로 인식하는 내부화 (internalization)를 관계마케팅의 궁극적인 목표로 제시하였다. 소비자들의 관계 내부화를 위한 관계강도(relationship strength)와 4개의 선행변수-analogy, approbation, availability, stakes-로 구성된 관계마케팅구조방정식 모델을 유통경로의 최종 단계인 소비자-소매업자(C-R)그리고 소비자-제조업자(C-M)관계에 적용하였다 서울의 5개 백화점 소비자들로부터 수집된 자료는 AMOS 4.0과 SPSS 10.0프로그램을 통해 분석한 결과, 본 연구의 제안모델은 통계적으로 검증되었고, 검증된 결과는 나아가 소매업자-소비자-제조업자의 3자 네트웍을 바탕으로 한 총체적 관점의 관계 내부화 모델 설계를 위한 하나의 실증 예로 사용 될 수 있음을 시사하고 있다.

Purpose - This study suggested a practical model for super supermarkets (SSMs) and small- and medium-sized stores to grow together. Super centers expanded their business. However, after the retail distribution law was revised in 2009, mutual cooperation between large and small enterprises resulted in social issues and people raised the issue of profitability. Research design, data, and methodology - This study investigated cases of regulation over distribution in Japan, France, and other countries to reveal implications and recommendations. Results - This study demonstrated how SSM and middle and small supermarkets could grow together by franchising and using cooperative society law. Franchising was a mutual growth model whereby the franchiser provided franchisees with large enterprise systems and utilities while franchisees could provide the franchiser with local information. They could thus build trust in each other to facilitate a mutual growth model. Further, the voluntary franchise system's model facilitated the mutual growth model. Conclusions - This study demonstrates that the franchise system and cooperative society could constitute an ideal model whereby large enterprises and middle and small stores could rely upon each other and grow together.

The purpose of this study was to investigate the relationship between retort food characteristics and consumers' perceptions and to survey 295 consumers from December 10 to December 20 as the center of consumers who purchase retort food. As a result, most of the consumers who purchase retort food were women and the age were under 25 and 26 to 30 years old. There were many housewives and students in the occupation group and 2 to 3 in the family members. In addition, many graduated from college and many places of purchase were convenience stores and large discount stores. Consumer retort food purchase rate were high by 30-40% in meat products. Fish meat products were high by 30-40% and sauces were high by 20-30%. Instant foods were high by 20-30%, Tang (탕) / Guk (국) / Jigae (찌개) were high by 30-40% and canned food were high by lower than 10%. As a result of the influence of retort food characteristics on positive perceptions only convenience were influential. The effects of the characteristics of retort food on negative perceptions were influenced only by hygiene and standardization.
