현재 우리나라에는 축구, 농구, 야구, 배구 등이 프로스포츠로 운영되고 있다. 이러한 프로스포츠의 주상품은 경기장 안에서 펼쳐지는 스포츠 경기이며, 스포츠 소비자인 관중이 상품인 프로경기를 구매하는 것은 경기장을 찾는 행동으로서 나타난다. 이에 따라 경기력과 관중 수 간의 관계에 대한 보다 실증적인 연구가 요구되는바, 본 연구에서는 2000년부터 2007년까지의 우리나라 프로축구인 K-리그를 중심으로 경기관련 요인 중 전력평준화지수를 측정하고, 이를 토대로 관중 수와의 상관관계를 분석해 봄으로써 전력평준화지수가 관중 수 증가에 유의한 영향을 미치는지 알아보았다. 그 결과 통계적으로 유의하지는 않음을 알 수 있었다. Currently, we have many professional sports such as soccer, basketball, baseball, volleyball in Korea. The main products of these professional sports are sports games. For spectators as a consumer buy professional games to show in their manner. According to this, correlation between the performance leveling indexes and the number of spectators must be established by evidence. In this paper, from in the year of 2000 to 2007, with Korean Professional Football League, we had to measure the performance leveling indexes among the factors related games. On the basis of this, by analyzing correlation of the number of spectators, we found out how the performance leveling indexes influenced the number of spectators. As the result of this, considering that statistically, we knew they had no bearing on each other.

This study seeks to determine the effects of the quality of services by the family restaurants on the customers' commitment to revisit and their brand recognition, by surveying college students who have used family restaurants. For survey results, this study used mainly SAS 8.0 accompanied by SPSS 11.0 to analyze the answers. For sampling, college classes were visited and surveyed the students is the classes. The answers have been retrieved right after students finished answering. When students asked for clarification on the questions in the survey, extra explanation was given in greater details in order to reduce errors that might be caused by the students' misunderstanding.

The purpose of this study is to investigate the structural behavior of the Gukrak-Paviliion of Bulkuk-Temple on gravity load with the 3-dimensional structural analysis. The structural approach of the traditional wooden structure is difficult because those structures are connected with large or small members by mortise locks, dovetails and so on. Despite small architectures need a number of members for analysis. Especially, bracket set is concentrated with members such as Salmi and Chumcha. It applied the equivalent model to bracket set. The target is the Gukrak-Pavilion of Bulkuk-Temple. This Pavilion has a large number of bracket set and explicit classification of Salmi and Chumcha.

The purpose of this study is to develop an simplified equivalent model to investigate the structural behavior of the Gukrak-Paviliion of Bulkuk-Temple subjected to gravity load using a three-dimensional structural analysis. The structural analysis of the traditional wooden structure is difficult because they are connected by mortise locks, dovetails and so on which are difficult to model. Especially bracket sets are congested with many members such as Salmi and Chumcha and may be analyzed correctly only by three-dimensional finite element model. In this study the bracket sets are modeled by equivalent linear members in such a way that the energy of the bracket sets is equal to that of the equivalent model. According to the analysis results the vertical deflection of the bracket sets obtained using the equivalent model is in good agreement with the displacement obtained by finite element model. The analysis results using the equivalent linear model showed that some members such as the connecting beams, architraves, and roof purlines located across the wide span are under stress close to or even larger than the allowable stress.

Objects: The purpose of this case-control study was done to examine the relationship between stroke prevalence and the anthropometric indices(body mass index(BMI), modified Broca's method(Broca's index), waist circumference(WC), waist-hip ratio(WHR)), dyslipidemia, past medical history(heart disease, hypertension, diabetes mellitus(DM)), life-style factors(smoking, drinking) in Korean adults. Methods : The study group consisted of neurologically confirmed 116 stroke patients as the case group and 116 non-stroke patients as control group. Obesity were defined as $BMI{\geq}25kg/m^2,\;Broca's\;index{\geq}30%$, WC >94cm in male and WC >80cm in female, $WHR{\geq}0.9$ in male and $WHR{\geq}0.8$ in female. Oyslipidemia were defined as total $cholesterol{\geq}200mg/dl,\;triglyceride{\geq}200mg/dl,\;HDL-cholesterol {\leq}35mg/dl,\;LDL-cholesterol{\geq}160mg/dl$. Information on life-style factors and past medical history was obtained from personal interview. The analysis of the data was done by means of chi-square test(Pearson's chi-square test, Fisher's exact test) and student t-test. Results: The results were as follow. In the study group: Hypertension had a 4:05 odds ratio, Broca's $index{\geq}30%$ had a 1.98 odds ratio, WC >94cm in male had a 2.17 odds ratio, WC >80cm in female had a 2.80 odds ratio, $WHR{\geq}0.9$ in male had a 4.66 odds ratio, $WHR{\geq}0.8$ in female had a 5.35 odds ratio, but heart disease, DM, life-style factors, serum lipid and 8MI had no direct relationship with odds ratio(nonsignificant). By student t-test, risk factors for stroke were found to be total cholesterol(p=0,025), LDL-cholesterol(p=0.013), WC(p=0.000) and WHR(p=0.000). Conclusions: This study suggests that people should be advised to control hyperlitension, hyperlipidemia and obesity since these carry a risk of stroke.

In this study a seismic retrofit scheme for the reinforced concrete moment framed structures was investigated using steel bracing and moment frames. The analysis model structure is a 3-story 3-bay moment frame structure designed only for gravity load. The stress/strain concentration in brace-RC frame connection was investigated using finite element analysis. To prevent premature joint failure, steel moment frames were placed inside of middle bay of the RC frame. Two types of braces, steel braces and buckling restrained braces(BRBs), were used for retrofit, and the ductility and the strength of the structure before and after the retrofit were compared using nonlinear static and dynamic analyses. According to the analysis results, the strength and ductility of the structure retrofitted by the moment frames and braces increased significantly. The added steel frame did not contribute significantly to the increase of lateral strength mainly because the size is relatively small. 본 연구에서는 가새와 강골조를 이용하여 철근콘크리트 모멘트 골조의 내진성능을 보강하는 방법에 대하여 연구하였다. 해석모델은 중력하중에 대해서만 설계된 3층 3경간의 RC 모멘트 골조 건물이다. 먼저 유한요소해석을 이용하여 RC구조물과 가새 접합부의 응력/변형 분포 상태를 파악하고, 접합부의 응력 집중현상을 방지하기 위하여 철골 모멘트골조를 추가하여 보강설계를 수행하였다. 내진보강을 위한 가새는 일반 철골 가새와 비좌굴 가새의 두가지 종류의 가새를 적용하고, 보강 전후 구조물의 강도 및 연성도를 비선형 정적 및 동적해석을 통해 비교하였다. 해석결과에 따르면 추가되는 철골 모멘트골조와 가새를 동시에 사용할 경우 구조물의 강도 및 연성능력의 증가에 큰 효과가 있는 것으로 나타났다. 추가되는 철골 모멘트골조는 단면이 크지 않을 경우 강도의 증가에 큰 영향을 미치지 않는 것으로 나타났다.
