The research is focused on planning the politic direction and on establishing an activating planning for retailer shops such as traditional market, super supermarket, discount store in Daejeon. The empirical study shows that the consumers most satisfied with discount store, meanwhile least with traditional market. Especially, it is proved that parking facility is the most important factor affecting consumer's satisfaction. This study also suggests some important strategic implications through IPA (important- performance analysis). Those are, first, the traditional market needs to improve for six categories of IPA factors, however the super supermarket for four, and the discount store for three. Second, the discount store has eight prominent advantages of the factors, however the super supermarket has seven, and the traditional market has five. Finally, the traditional market has to concentrate facility improvement for consumer's convenience in the long term.

More manufacturing companies tend to outsource their logistics functions to logistics service providers to ensure their own competitiveness than before. This paper investigates the differences between customer perceptions and expectations on three key logistics outsourcing decisions. For testing logistics service qualities, a research model which employs a SERVQUAL model was developed and a survey targeting manufacturing companies has been conducted. The average difference of logistics service level between customer perceptions and expectations was derived as 8% from a result of gap analyses. The findings here reveal the level of service quality of Korean logistics service providers as well as suggest core capabilities for them in order for gaining a competitive edge on the competitors and improving their performances.

발주잔량의 감소와 세계경기 회복기조 등을 감안할 때, 수급여건은 저점에 근접해 있다. 그러나, 해상물동량 증가율의 둔화, 대형선박 위주로 되살아난 발주 등을 감안할 때, 운임지수 등 시황회복은 상대적으로 느리게 진행될 전망이다. 2012년부터 상위선사의 뚜렷한 실적차별화가 나타나고 있으며, 국내선사는 상대적으로 취약한 선종다각화와 자본력, 계열 및 정부의 저조한 지원 등으로 금융위기 이후 재무구조가 가장 큰 폭으로 악화되었다. 상위선사의 실적우위는 일시적 차이가 아닌 선박의 대형화와 높은 연료효율성, 우수한 글로벌 네트워크 등 구조적 원가경쟁력의 차이에 기인하고 있다. 상위 3개 선사는 초대형선박의 추가인수와 P3 Network 구축으로 원가경쟁력이 더욱 향상될 전망이며, 재무여력을 갖춘 경쟁선사들도 선박가격이 낮은 상황에서 고효율의 대형선박을 발주, 원가경쟁력을 제고하고 있다. 반면에 호황기 고가에 선박을 확보한 국내선사는 과중한 재무부담으로 인해 선박대형화와 글로벌 네트워크 구축에 동침하지 못하고 있어 원가경쟁력의 차이는 더욱 심화될 전망이다. 더딘 시황회복과 상위선사의 단위당 운송비(Unit Cost) 하락 등을 감안할 때, 빠른 시일 내에 운임상승을 통한 큰 폭의 성과개선을 기대하기 어렵고, 과중한 재무부담은 투자여력의 위축으로 이어지고 있다. 여기에 중국 유럽선사가 정부로부터 대규모의 직접적 지원(대출, 지급보증)을 제공받고 있는데 반하여, 우리 정부는 장기적 관점의 지원이나 대책을 유보한 채, 제한된 유동성 지원만을 하고 있다. 재무부담에 따른 악순환을 깨고 원가경쟁력을 확보하기 위해선, 비핵심자산 매각, 자본유치 등 구조조정을 통한 재무구조 개선, 투자여력 확보를 통한 글로벌 경쟁력 회복, 정부차원의 지원과 조정 등 가능한 모든 방안을 총 동원하여 재무구조를 개선하고 투지에 나서는 것이 시급하다. 하지만, 불황으로 체력이 소진된 해운사의 자체적인 노력만으로는 한계가 있다. 기간산업의 국가경쟁력 차원에서 국내 선사의 자체노력은 물론, 정부 또는 금융기관 등 유관기관들의 확실한 지원이나 의사결정이 필요한 시점이다. 그렇지 않을 경우 국내 해운산업은 어두운 터널의 끝을 벗어나지 못하고 글로벌 경쟁사와의 격차는 더욱 벌어지게 될 것이다. 다음은 한국신용평가에서 발표한 "풍전등화 국내 해운업계, 본원적 대책 마련 시급"의 주요 내용을 요약 정리한 것이다.

It is widely accepted that there are first mover advantages in various existing industries. However, few studies have been conducted to evaluate the first mover advantages shown in the foodservice industry, whether first movers practically have first mover advantages, and what effects these advantages have on foodservice enterprises. Specifically this study was designed to identify the relationship between first mover advantages and business performance in the foodservice industry. To accomplish this, questionnaires were sent to and collected from selected first movers consisting of 70 foodservice franchised enterprises. SPSS 15.0 was then employed to conduct factor analysis, reliability analysis, correlation analysis, and regression analysis. The analyses revealed that the franchised foodservice enterprises could provide several strategies that enabled them to grow quickly and to establish more shops in their market. In addition, having a greater number of shops resulted in greater advantages when compared to their competitors. Moreover, the advantages of first movers had a significant effect on their business performance. Taken together, these findings imply that if foodservice enterprises franchise their business as early as possible, they can more easily preoccupy their market and enjoy more first mover advantages. This study is meaningful and differentiated from existing studies in that it investigated first mover advantages of the foodservice enterprises in the appropriate industry.

The shape of a iron bed supporting a permanent magnet in a large-sized motor is a important factor for determining the coupling strength with the yoke. In a large-sized motor, there is a difference in electromagnetic force with the yoke depending on the shape of the iron bed. In this paper, we show the differences and problems by calculating the electromagnetic force between the double bed and the single bed through the virtual air gap, and show that the single bed is superior in terms of the binding force. It is also shown that the binding force between the bed and the yoke is improved by carving the groove shape under the bed.

The objective of this study is to analyze domestic air passengers' preferences for selecting domestic airline company. By the analytic hierarchy process(AHP) method, we tried to measure the weight of the qualitative factors objectively and scientifically. The overall results indicate that domestic air passengers place more weight on airport service factor than other service factors for selecting domestic airline. Also, reservation/ticketing and in-flight service factors are equivalent to airport service factor. These priorities are differently shown followed by passengers' income. Therefore, airline companies need to formulate the differentiated strategy and customer-oriented marketing plan based on identified customer needs.

Using KRIVET's Graduates Economic Activities Survey for 2005, this article examines the relationship between university ranking and labor market outcome, with a focus on wage differentials existing between provincial and Seoul metropolitan area university graduates. According to the analysis results, the average monthly wage for provincial university graduates was 1,747.7 thousand Korean won, which is 11.5% lower than that for graduates of universities in the Seoul metropolitan area. School effects on individual wage were estimated to about 12.2% after applying Hierarchical Linear Model technique, which means that university explains only an insignificant part of the total variance in wage among graduates. After controlling for the selection bias, the ability difference between the two areas, by applying the Heckman type 2SLS wage function and Neumark wage differential decomposition technique, the wage gap resulting from the segregation was not identified. This implies that, to a significant extent, the wage gap between provincial and Seoul metropolitan university graduates is attributed to the difference in productivity among individual graduates, rather than to the wage segregation. Also, the estimated wage function by applying Quantile Regression technique indicates that there does not exist any significant wage segregation difference by wage quantile.

This study conducted a comparison analysis on the difference in the subjectivity structure of Korean and Chinese consumers based on their types of perception on advertisements of automobiles which has a high degree of self interest. The primary reason for conducting a comparison study of Korean and Chinese consumers was to concretize the characteristics of Chinese consumers who have enormous potential and rapid growth in the global market. In addition, by comparing the characteristics of Korean and Chinese consumers that changed with differences in social systems and socio-economic characteristics, the purpose was to present an advertising strategy idea that is useful for both countries. Furthermore, when taking into consideration the reality that the world must compete in a single market commonly referred to as the global market, understanding the subjectivity structure of perception of Korean and Chinese consumers is critical in establishing a strategy for occupying the upper position of dominance in such competition. Based on the results of the study, subjectivity structures on the perception of advertisements possessed by Korean and Chinese consumers of the same Asian culture differed but were mutually interrelated. Such results suggest that there is a need for further studies of generalization and objectification through a quantitative approach.
