  • ASCE-ACI Committee 426 and 445, on Shear and Torsion, well noted in their report that recent research work regarding shear and torsion had been devoted primarily to members. But it was not logical approach of PSC members applied by axial force based on the shear deformation in web element. And it was not included that the effect of axial is to shift the shear strain(or crack width) in the web element versus the applied shear curve up or down by the amount by which the biaxial tension-compression state varies. The shear strength also increases or decreases, so that the change in shear strain at service load due to the presence of axial load is to some extent changed. Generally, in corresponding beams the shear strain at service load is less in the beam subject to axial compression and greater in the beam subject to axial tension, than in the beam without axial load. In particular, however, no research were available on the shear deformation in shear of PSC members with web reinforcement, subject to axial force in addition to shear and bending. Therefore, this study was basically performed to develop the program for the calculation of the shear deformation based on the shear effect of axial force in prestressed concrete members.

  • 대학도서관의 조직과 인원이 이용자와 서비스를 중심으로 바뀌어 가는 과정에서 나타나기 시작한 주제별 자료실 조직구조는 국내 185개 대학도서관중 56개 도서관(30.2%)이 채택하고 있는 것으로 조사되었으며 지속적으로 그 수가 늘고 있는 것으로 파악되었다. 이에 따라 보다 한국적 상황에 맞게 적용시키고 효과를 극대화하기 위해서는 자관의 현실과 상황을 고려한 체계적인 절차와 과정을 통해 준비되어져야 할 필요가 있다. 또한, 적용모델에 있어서는 국내 대학도서관 현실과 물리적 지원의 한계를 고려할 때 도서관의 전체적인 조직구조에 있어서는 기존의 기능별조직을 유지하고 자료구분 및 참고봉사를 포함한 이용자 서비스 부분만을 주제별조직구조로 유지하는 혼합형 구조가 바람직하며 인적요소와 조건이 충족될 경우 일체형 구조를 지향하는 것이 바람직한 것으로 파악되었다.

  • Under the competitive environment of shipping industry, the improvement of the quality of shipping service could be one of the most important factors to be considered in the recent shipping industry. However, there has been little study on the clear concept of the service quality in the shipping so far. The subject of this study is to define the concept of the service quality in the shipping by way of making investigation into the related precedent literatures studied. The quality of service is recognized in general as a degree of gap between the customer's expectation and the perception. Therefore the service quality of shipping could be measured by evaluating the gaps between shipper's expectation and performance of shipping service. If the determinants of the service quality in the shipping are proved, and the discrepancies of expectations and perception between the shipping company and the shipper could be clarified, such a result would be an useful help to establish marketing strategy.

  • This study was the development of job-based curriculum present the basic data for the 207 people surveyed dental hygienists in clinical analysis. The data was analysed with frequency, t-test and one-way anova using the spss 20.0 windows. Person of preventive dental treatment in main duty was significantly highest than among others. In conclusion, the dental hygienist will perform the most medical support services, However the main duties of dental hygienists to perform preventive dental treatment for major help when the highest degree. Among oral hygiene management duty-related subjects showed the most helpful. Therefore dental hygiene curriculum to train dental hygienist should be organized to help with job performance in the field of clinical activities.

  • We consider a single channel CSMA/CD system with D homogeneous stations and impeded buffer of infinite size. We find a sufficient condition for the model to be stable under the threshold control policy and derive the limiting distri-bution of the number of messages in the system at the moment of service completion. We also derive the limiting distributing of the number of messages in the system size at arbitrary time by using Markov regenerative processes. Some numerical examples and special cases are also treated.

  • 하수시설 자산관리체계 구축에서 가장 중요한 요건중의 하나는 하수 서비스 공급을 위한 관리 수준을 결정하는 것이다. 하수관련 시설이 건설되고 나면 운영단계에서 발생하는 개 대체 항목의 많은 부분들이 민원이나 사용자의 요구에 의해 이루어지게 된다. 이러한 서비스 수준을 관리하기 위해서 어느 지역에 어떤 민원이 주로 발생하고 있으며 어떤 부분을 개선시킬 것인지를 찾아 서비스 관리 목표를 설정하는 것이다. 본 연구에서는 이러한 점을 반영하여 국내 자산관리 수행이 진행되고 있는 S지역의 하수 민원대장을 분석하였으며 이를 토대로 지역 특성별로 민원발생 대상 시설과 민원 발생 유형을 분석하여 서비스 제공 관리기준을 개발하였다. 이를 선진 하수시설 자산관리 밴치마킹 대상지역과 비교하여 S지역만의 Best Practice 구현을 위한 기준을 설정하였다.

  • Vessel Traffic Service (VTS) is the service that provides ships navigating on a sea transportation route with guidance and advice about geographical environment and other attentive information for their safety. In this study we point out that currently, constructing additional VTSs is required to prevent ships from unexpected accident on their navigation. We first select several candidate locations for constructing VTSs, based on the amount of marine transportation and its potential development possibility. Then, we present an optimization model in which the maximum area coverage is achieved by determining new locations of VTS subject to budget limitation. The problem can be modeled as a binary integer program and it provides an optimal solution for new VTS locations to be constructed under the consideration of the currently located VTSs in Korea.

  • The purposes of this study are to determine dimension of apparel expectations. performances and service quality of home shopping and thereby, to analyze effect of apparel commodities dimension (expectations, performances, disconfirmation and satisfaction) and service dimension (service quality and satisfaction) on repurchase intention. The subject were 351 women in the age of twenty to sixty years old who live in Seoul and the suburban of Seoul. The results of this study can be summarized as follows : 1. It was found that home shopping consumers' expectation and performance with apparel commodities were classified 3 factors. On the other hand, the dimensions of service quality were found to have such 3 factors as convenience reliability, personal factor, and apparel one. 2. More frequent users of home shopping scored more on average than less frequent users in terms of service quality, service satisfaction and intention of repurchase. On the other hand, the cable TV users scored more on average than catalogue users In terms of service quality and intention of repurchase. 3. It was found that consumers' intention of repurchase of home shopping were affected by such variables as discofirmation and satisfaction with apparel commodities, service quality and service satisfaction. While less frequent users were affected by disconfirmation and service quality, more frequent users were affected by such variables as apparel commodities satisfaction, service quality and service satisfaction. Meanwhile, both cable TV and catalogue users were found to be affected by service quality and service satisfaction.
