The main objective of this paper is to provide analysis of obesity index of residents in six metropolitan cities. According to analysis of Rohrer Index, there was significant difference regionally between men and women in metropolitan cities. Through analysis of Drop Value, it was found that there were significant differences regionally between men and women in metropolitan cities on circumferences of chest, waist and buttocks. The result of this research can be utilized in manufacturing and design of uniforms and equipments for safety.

There are many Korea companies who are introducing many kinds of management renovation methods in order to attain more management achievement. So many personnels under CEO are frying to change themselves to fit those kinds of management renovation methods. Now, all kinds of books for supervisors have published, but it is not easy for those supervisors to understand those books as those books do not fit for their own companies situation. The best management methods in the best companies in U.S.A. actually can not be well introduced in Korea. So, the management methods should be changed with the environment's changing. Therefore, the company management is the process to suit the continue changing environment.

The Location Based Services (LBS) comprise spatial information and mobile technology allow users to receive various services based on Global Positioning Systems (GPS). Although, spatial information based services are very useful, it has lots of possibility to damage privacy protection. But the contents of the legislation by government have problems conflicted between protection of a person's location information and invigoration LBS. Therefore, in this study suggest a causal model to deal with user satisfaction and factors affecting spatial information based services to customer perspective. The proposed research model is tested empirically with one hundred and forty one usable questionnaires and partial least square (PLS) method. Experimental results showed that the usefulness, playfulness, and service quality play a prominent role in influencing the spatial information services satisfaction compared to other factors. But, easy of use and perceived risk are not significant.

The development of information technology, which has brought the fusion of broadcasting and telecommunication, wire and wireless communication and voice and data, is developing new fusions like home network which is composed of IT, construction, and home appliances. This trend is considered to continue and to make other new fusions based on previous ones. In this study, we investigate the roles of RFID middleware by identifying the relationships between the new expected fusions and RFID.

In spite of the development of the service industry, research on measuring customers' service satisfaction is far insufficient. Therefore, ways to measure the service qualify accurately need to be established due to the ambiguous types of service business. This research classifies the types of service business into service factory, service shop, mass service, professional service by using Schmenner's Service Process Matrix and conducts research on domestic literature that measured service satisfaction with Servqual and ServPerf. This study intends to suggest guidelines to measure customer satisfaction according to types of service business by researching ways to measure service satisfaction according to the types of service business and analysing the actual application methods based on a table that summarizes previous research on Servqual and Servperf.

오늘날 제품이 문제가 되는 경우는 별로 없다. 그런데 불행하게도 재화를 만들고 용역을 제공하는 많은 기업들은 제품 하나에만 관심을 쏟고 있다. 정작 중요한 것은 고객의 소리를 듣는 것이다. 서비스 산업에서 특히 이것은 아주 중요하다. 서비스 관련 여러 요소 가운데 중요도를 선정하여 서비스 품질을 린 프로세스적 사고로 서비스 요소중의 낭비를 제거 한다면 소비자에게 불필요한 서비스가 아닌 진정한 가치를 선사하는 일이 될 것이다.

본 논문의 목적은 과거의 산업 포트폴리오 수익률이 확률추세로부터 어떻게 전체 주식시장과 두 가지 거시경제 변수인 경기동행지수와 산업생산 등을 예측할 수 있는 지를 알아보는 데에 있다. 이를 위하여 본 연구에서는 연구모형을 설정한 후 세 가지 검정절차를 제시하고 이를 실증적으로 분석하였다. 당월의 전체 주식시장 수익률은 과거의 시차를 지닌 특정 산업부문 포트폴리오 수익률에 대하여 양(+)의 상관관계를 유지하고 있다는 '예측 1'과 전체 주식시장의 수익률은 특정 산업부문의 수익률에 대하여 선행성을 지닐 수 없다는 '예측 2'에 대한 검정 결과는 '예측 1'과 '예측 2'가 지지되고 있음을 파악할 수 있었다. 그리고 산업별 포트폴리오 수익률과 거시경제변수 간의 높은 상관관계를 토대로 하여 전체주식시장 수익률 예측을 가능하게 하는 업종 정보의 점진적 확산 현상이 발생하게 되는가를 검토하기 위하여 각 산업들의 포트폴리오 수익률과 전체 주식시장 수익률이 VAR모형을 토대로 볼 경우 Granger 인과관계를 갖고 있는 지를 분석하였다. 분석결과 21개 업종은 각 산업별 포트폴리오 수익률이 전체 주식시장 수익률을 5% 수준에서 통계적으로 유의한 영향을 주고 있음을 알 수 있었다. 이들 21개의 산업별 포트폴리오 수익률은 경제적으로도 중요한 의미를 지니고 있어 산업제품의 가격 상승과 하락이 경제에 미치는 영향을 파악할 수 있다. 특히 음료 업종에서 전체 주식시장 수익률과 상호간의 인과성을 나타내었으며, 인터넷과 화장품 업종에서는 전체 주식시장 수익률이 이들 업종에 대하여 일방적인 영향을 보이고 있음을 알 수 있었다.
