Generally, headed reinforcement offers several advantages over straight bar or hooked bar anchorages to develop reinforcement in concrete members. The purpose of this study is to investigate the shear behaviors of reinforced concrete deep beam with headed reinforcement. Five deep beam specimens are designed to study the anchorage capacity of headed reinforcement as well as the contribution of H-bar and V-bar to the shear. Two anchorage types, standard 90-degree anchorage and headed reinforcement, are considered in design. From the tests, it is shown that In the test results, headed reinforcement is able to replace standard 90-degree anchorage as the anchorage method. The evaluation on the contribution of H-bar and V-bar in current design code for deep beam shows that the former is overestimated 75% and the latter is overestimated 17%.

본원 소아과 입원환자의 퇴원요약 기록을 전산관리하는 시스템을 개발하였다. 소아과 환자관리에 적합하도록 퇴원요약지를 설계하였고 개인용 컴퓨터를 사용하여 관리하도록 구성하였다. 주 기억장치 4MB와 보조기억 장치 120MB HDD을 장착한 PC-386DX 시스템을 기반으로 개발하였고 소프트웨어로는 FoxPro v2.0을 사용하였다. pull-down menu 방식과 window방식을 적용하여 비전문가라 할지라도 손쉽게 사용할수 있도록 하였고 정보입력 및 수정시 사용자 편의를 최대한 반영하고자 하였다. "AND"와 "OR"연산자를 사용하여 다양한 검색이 가능하였다. 본 시스템은 현재 본원 소아과에서 실무에 적용하고 있으며 향후 통계분석과 임상연구에 크게 활용할 수 있으리라 생각된다. A PC-based system was developded to manage discharge summary records of pediatric patients. It is based on a PC-386DX system equipped with 4MB memory and 120MB HDD, and its software was written in FOXPRO V2.0. Any users unfamiliar with computer can make an easy access to the data through pull-down menu and windows system. Logical operators of "AND" and/or "OR" enabled a flexible and various search conditions. The present system is being under clinical use in the Department of Pediatrics, and warrants future applications to statistical analysis as well as clinical research projects.

The purpose of this study is to explore alternative models in credit risk analysis and contrast them with traditionally used statistical models, e.g., financial ratio models, discriminant analysis models and LOGIT models. The paper, first, discusses fundamental concepts of statistical models. Then, it examines three alternative models: a neural-network model, an AHP models and an expert system model. Theoretical backgrounds and advantages and disadvantages of each model are examined and compared. Finally, actual application cases of these models are discussed.

Artificial neural network(ANN) models have been widely used for the classification problems in business such as bankruptcy prediction, credit evaluation, etc. Although the application of ANN to classification of consumers' choice behavior is a promising research area, there have been only a few researches. In general, most of the researches have reported that the classification performance of the ANN models were better than conventional statistical model. Because the survey data on consumer behavior may include much noise and missing data. Ann model will be more robust than conventional statistical models which need various assumptions. The purpose of this paper is to study the potential of the ANN model for forecasting consumers' choice behavior based on survey data. The data was collected by questionnaires to the shoppers of department stores and discount stores. Then the correct classification rates of the ANN models for the training and test sample with that of multiple discriminant analysis(MDA) and logistic regression(Logit) model.

In response to a continuing concern that the federal government be held accountable to the American people, Congress enacted the Government in the Sunshine Act in 1976, requiring that all portions of all meetings conducted by federal agencies be open to the public unless they fit within one of ten exemptions. The Act reflects the feeling that greater accountability will increase the public's confidence in and understanding of the decision-making process. However, it is essential to keep in mind that the Act is a product of balancing the need for openness with the needs for personal privacy and administrative efficiency. So, it is necessary to find the middle ground between the benefits and the costs of open government. In order to do this, I will provide a general explanation of the Act's provisions, examining them in light of the stated policy of the Act, its legislative history, and the courts' decisions. In the conclusion, the current situation on the open government in Korea will be briefly described.

This study supposed that motivation of helping would be different according to social and cultural background, that is, egoism or altruism. Based on difference of helping motivation, it was proposed that content of egoistic helping was fairness and content of altruistic helping was fraternity in which were social values. The nature of helping behavior were classified in term of these two different social values. Therefore, the previous results of helping research reilluminated based on conceptual framework proposed in this study. Also, it was understood previous findings of helping study conducted in different concern in terms of one meaningful framework. According discussion in this study, the limitations of previous helping research were discussed and were proposed further research.
