  • This study aims to examine seven factors and forty-two selection attributes of Seoul as an Exhibition and Convention Destination Site through the Importance-Performance Analysis(IPA) from the Exhibition and Convention Planner. The result of this study shows these three conclusions. First, according to the result of the Importance-Performance Analysis(IPA) of the forty-two selection attributes of an Exhibition and Convention Destination Site, thirteen attributes were placed on the right top area(Keep Up the Good Work), four attributes were placed on the right bottom area(Possible Overkill), five attributes were located on the left top area(Concentrate Here), and the other twenty attributes were located on the left bottom area(Low Priority). Second, the Importance-Performance Analysis(IPA) of seven factors in an Exhibition and Convention Destination Site reveals that the factors in the right top area(Keep Up the Good Work) of high importance and high performance were "Exhibition and Convention Center Facilities", "Exhibition and Convention Fee", and "Exhibition and Convention Center Accommodation Capacity". And the one factor located on the left top area(Concentrate Here) of high importance and low performance was "Exhibition and Convention Destination Regional Space", while the other factors of "Exhibition and Convention Center Management", "Exhibition and Convention Destination Tourism Space" and "Exhibition and Convention Destination Leisure Activity Space" were placed on the left bottom area(Low Priority) of low importance and low performance. Third, the difference of the mean value of the Importance and Performance on Seoul as an Exhibition and Convention Destination Site has been revealed that the performance of the attributes was lower than the importance of the attributes because forty attributes have described all plus(+) except two attributes.

  • Using an ellipsometer with dual rotating quarter-wave plates, we have analyzed the relationship between Fourier coefficients and Mueller matrices in the cases of an error-free optical system and of five systematic errors (alignment errors and retardation errors in the quarter-wave plates, and alignment error in the analyzer). In the case with five systematic errors, simulation results show that retardation errors cause more error in the diagonal elements of the Mueller matrix than do alignment errors. We have found that errors in the Mueller matrix caused by initial misalignment of the dual quarter-wave plates were the same. We have chosen the rotation rates of two quarter-wave plates such that the rotational frequencies ${\omega}_1$ and ${\omega}_2$ differ by a factor of 5, i.e. ${\omega}_2=5{\omega}_1$. The simulation results show 0.18% relative error in the diagonal elements ($m_{22}$ and $m_{33}$) and 200% relative error in the off-diagonal elements ($m_{23}$ and $m_{32}$), when we compare errors caused by misalignment of the analyzer to those caused by initial misalignment of the quarter-wave plates. We can use these results in measuring accurate Mueller matrices of optical materials.

  • The purpose of this study is to research hotel restaurant's servicescapes using Important-performance analysis. IPA is one of the simple and efficient method that can enhance service quality and customer satisfaction. Using this method for hotel restaurant's servicescapes and adopting social exchange theory to find out difference between person who paying and who does not. The results shows difference in 'Possible Overkill' quadrant, which is only group that does not pay include contents No.2, 8. The relation between servicscapes and behavior intention shows only tangible environment factor has positive effect.

Tetraspore Release and Growth of a Crustose Coralline Alga, Lithophyllum yessoense (Rhodophyta, Corallinaceae) (홍조류 무절석회조, 납작돌잎 (Lithophyllum yessoense) 사분포자체의 포자방출과 생장)

  • Growth and tetraspore release pattern of lithophyllum yessoense (Rhodophyta, Corallinaceae) were investigated from March 2000 to July 2001. Pinkish tetraspores were 40.2 $\pm$ 0.4 $\mu$m in diameter. After release, tetraspores attached on substrate shortly. Culture conditions were five temperatures (5, 10, 15, 20, 25^{\circ}C), four irradiances (0, 20, 50, 100 $\mu$mol${\cdot}m^{-2}$${\cdot}s^{-1}$) and six salinities (0, 9, 17, 25, 34, 43 ppt). Maximum growth of gametophyte was occurred at $20^{\circ}C$, $20{\mu}mol\;m^{-2}$${\cdot}s^{-1}$, 16: 8h (L:D) and 34 put. Maximum relative growth rate was 0.1232 at $20^{\circ}C$. The amount of tetraspore release showed maximum at September as 266 cells per crust area ($cm^2$), and tetraspores did not release from January to March.

  • 자율 이동로봇은 현재 각광을 받고 있는 서비스로봇의 연구와 더불어 활발히 연구되고 있다. 그 중 경로계획 부분에 대한 연구는 Roadmap Method, Cell Decomposition, Potential Field Method로 크게 구분하여 연구되고 있다. 그러나 경로계획 기법에 있어서 기존의 정형화된 방법 이외에 다른 방법들이 제시 되지 않고 있다. 기존 경로계측의 문제점들은 다음과 같다. 국부최소(local minimum)를 회피하지 못하거나, 많은 계산량으로 인해 넓은 범위에 적용시킬 수 없다는 문제점, 오프라인으로 경로의 최적성에만 치중하여 실시간으로 적용하기가 쉽지 않으며, 돌발적인 상황에 대처하기 어렵다는 문제점 등을 가지고 있다.(중략)

  • 1965년 건축사 자격증 제도가 생긴 이래로 내년이면 대한건축사협회도 50주년을 맞습니다. 긴 여정의 건축계를 돌아보니, 앞서가신 원로 건축사들의 여정이 궁금해집니다. 60년대부터 현재까지 세계가 놀랄 만큼 눈부신 발전을 한 우리나라를 둘러보니, 경제 성장만큼이나 성장한 건축물들이 우리 주변을 둘러싸고 있습니다. 그 현장 곳곳이 선배 건축사분들의 발자취가 아닐까 합니다. 오늘 이 자리에는 70, 80대 건축사분들이 함께 했습니다. 함께하는 자리에서 선배님들의 주옥같은 역사를 들어보겠습니다.

  • This study intends to examine the effect of the teenagers' selection attribute and satisfaction of fast food menu. Sampling was taken among the students of high schools at Changwon in Kyungnam province, and a total of 400 samples were distributed, among which 306 valid samples were used for analysis. After date cording, answers were processed by SPSS 12.0. As a result of the IPA analysis, the 1st quadrant included 8 variables, the 2nd quadrant 6 variables, the 3rd quadrant 5 variables, and the 4 quadrant 8 variables. Also, as a result of the factor analysis for menu selection attribute, 5 factors(atmosphere, food, staff, comfort, compensation) were extracted. It was found that only food has a statistically significant impact on satisfaction with fast food.
