본 연구에서는 서해안 ${\bigcirc}{\bigcirc}$지역에서 IPS 지지방식과 Strut 지지방식으로 시공한 현장의 계측에 의한 수평변위량을 수치해석상의 예측치와 비교하고, 실무에서 널리 사용되고 있는 탄소성보법 해석 프로그램(SUNEX, EXCAV)을 이용하여 해석치를 상호 비교분석 하였다. 또 최대수평변위에 대한 여러 제안값 중 점토지반에 적용한 제안값과 비교한 결과, IPS 지지 방식과 Strut지지방식에 의한 최대 수평변위는 IPS지보형식이 Strut지보형식보다 더 크게 발생하였으며, SUNEX 프로그램 해석치와 EXCAV 프로그램 해석치를 상대 비교했을 때 SUNEX 프로그램이 더 크게 해석되었지만, 점토층에서의 기존 제안값인 0.5%H 에는 더 근접하다는 결론을 얻었다. 이는 SUNEX 프로그램이 해석 시 지보형식이나 사용하는 부재 보다는 토질 정수 중 내부마찰각(${\Phi}$)에 의해 수평변위값이 영향을 받기 때문이라 판단된다. 즉 내부 마찰각이 큰 사질토 지반에서는 수평변위값이 작게 발생하고, 내부 마찰각이 작은 점성토 지반에서는 수평변위가 크게 해석되어 상호 비교 시 사질토 지반에서는 EXCAV가 크게 나타나고 점성토 지반에서 SUNEX가 크게 나타났다고 판단된다. 또한, 기존 제안 값 중 점성토에 적용한 0.5%H와 비교 시 현장계측치는 평균 141%, SUNEX로 예측한 결과치는 평균 78.1%, EXCAV로 예측한 결과치는 평균 18.1% 범주에 분포함을 확인하였다. 따라서, 흙막이 가시설 설계 시사용하고 있는 해석 프로그램으로 산정한 수평변위량이 실제 현장에서 계측한 변위량을 과소 예측하므로 지반거동을 모사하는데 주의를 요한다. 추후 보다 정밀한 유한요소해석 등을 통하여 실제 거동의 예측 가능성을 평가해야 할 것이다.

The purpose of this study was to analyze the effects of consumers' fashion design evaluation factors on design value and brand loyalty. After confirming a research hypothesis, 247 people were selected as subjects for empirical analysis, and the results of the study are as follows. As a result of the analysis of 'the influence of consumer's fashion design evaluation factors on design value', the fashion design evaluation factors of 'convenience', 'social activity usefulness' and 'fashion ability' had an effect on the emotional design value. 'Convenience', 'functional usefulness', 'social activity usefulness', 'fashionableness' and 'aesthetic' factors affected the rational design value. 'Convenience', 'fashionableness', 'aesthetic' and 'psychological self-conformity' had a positive (+) effect on kinesthetic design values. As a result of the analysis of 'Influence of consumer's fashion design value on brand loyalty', 'emotional design value', 'rational design value' and 'kinesthetic design value' affect attitude brand loyalty, and 'emotional design value' and 'kinesthetic design value' affect brand loyalty. It was found that 'kinesthetic design value' has an effect on behavioral brand loyalty. As a result of the analysis of 'the effect of consumer attitude brand loyalty on behavioral brand loyalty', it was analyzed that attitude brand loyalty had a statistically significant positive (+) effect on behavioral brand loyalty.

Background: The purpose of this study is to emphasize the importance and necessity of the government's old-age preparation service by measuring the economic value of the old-age service and the policy direction and policy implications of the government's old-age preparation service project. Methods: Contingent Valuation Method (CVM) was used as an analytical method. CV methodology was used to calculate the Willingness to pay (WTP) for old-age preparation service and its value was estimated and the economic benefit of the project was estimated. Results: As a result of the analysis, the average monthly payment amount for the old service was calculated as 5,100 won, and the annual average payment amount was estimated to be 61,197.1 won. Conclusion: The present value of the benefit for 10 years with the discount rate of 5.5% is 484,651 won. Based on the value of peruser benefit, the total benefit value calculation result of the old-age preparation service considering the Willingness to pay for the next 10 years shows that the total benefit value of the old service, which occurs during the period from 2016 to 2025(10 years) was estimated at 415.1 billion won. As a result of calculating the benefit for each scenario, the present value of basic service is higher in all scenarios than the linked service.

The activated partial thromboplastin time (APTT) is used primarily to evaluate coagulation abnormalities in the intrinsic pathway. The proper specimen is very important factor for precise results of blood coagulation analysis. The objective of this study was to get to the conclusion of whether to analyze again and to collect blood sample over again when APTT result shows below the reference value. We evaluated 126 samples showing a value below 20.0 sec at ATPT result, which consist of 48 males and 78 females candidates during night duty from March 2012 to December 2012. Average comparisons of APTT result between first and retested analysis among study subjects were significantly different in male samples. APTT results comparison of recollected subjects among clotted samples were also significantly different with both sexes (p<0.000). We suggest that we should carefully check the samples to get accurate results and collect samples again in case of only obtaining improper samples; even though the APTT result show below reference value.

In acquiring and transferring a superior knowledge assesing the intermediate result value of a competitive R&D project is very important for a firm engaging in R&D. Most existing literatures on R&D evaluation are concerned with project selection and resource allocation. In this paper the stage of an R&D project is classified into research, exploratory development, and development. And a model is suggested which evaluates the intermediate result value before completion of development stage under duopoly and oligopolistic competition. Assessed value of the intermediate result transferred to the next tier company can be used as a minimum acceptable price to the inventor when more advanced knowledge acquired through R&D is transferred to the next tier one. The model suggested is composed of structural variables including research cost, success rates, potential profits, discount rate degree of competition. By using exponential distribution for invertion process time in each stage, we derive a formula that can assess the value of the intermediate result, and we demonstrate how the model can be applied to a competitive R&D situation through an example.

This paper presents an efficient filtering system for a metastable state-based true random number generator. To output a result with high randomness, we use loop-storage for storing the value of metastability. During the metastable state, the output value is accumulated to the storage. When the non-metastable state arises, the stored metastable value will be used for output instead of the result of the non-metastable state. As a result, we can maintain high entropy together with the original throughput.
