Function Point Method have been applied to measure software size estimation in industry because it supports to estimate the software's size by user's view not developer's. However, the current function point method has some problems for example complexity's upper limit etc. So, In this paper, an enhanced function point model. Micro FP model, was suggested. Using this model, software effort estimation can be more efficiently because this model has some regression equation. This model specially can be applied to estimate in detail the large application system's size Analysis results show that measured software size by this Micro FP model has the advantage with more correlative between the one of LOC, as of 10 applications operated in an large organization.

The existing Function Point method to estimate the software size has been utilized frequently with the management information system. Due to the expanding usage of the real-time and embedded system, the Full Function Point method is being proposed. However, despite many research is being carried out relation to the software size, the research on the model to estimate the development cost from the measured software size is inadequate. This paper analyzed the linear regression model and power regression model which estimate the development cost from the software FFP The power model is selected, which shows its estimation is most adequate.

본 연구는 공수방식이나 기능점수(Funtion Point)방식에 의존해 온 기존의 게임콘텐츠 원가산정 방식의 문제점을 인식하고 이를 대체할 새로운 게임요소점수(Game Element Point) 접근방식 하에서 구체적인 원가산정 방법론을 개발 제시하였다. 게임콘텐츠 원가산정 모델은 게임콘텐츠에 고유한 게임요소를 도출하여 이를 게임요소점수(GEP; Game Element Point)로 환산하고 여기에 게임요소당 단가를 곱하여 원가를 산정하는 형태를 가지고 있다. 또한 제시된 방법론의 실무적용 가능성을 타진하기 위해 게임 개발업체들의 실제원가 자료를 입수하여 실제 개발원가와 GEP방식으로 계산된 원가를 비교 검증하였다. 탐색적 수준의 사례 비교를 통한 검증결과 GEP방식의 적용이 가능하고 또한 기존방식을 대체할 좀 더 실무적이고 정확한 게임 컨텐츠 원가산정 방식으로 사용할 수 있는 것으로 판명되었다.

Discharge plans should be considered during rehabilitation depending on the location specified by the patients. This study aims to compare the demographics and rehabilitation function according to discharge location in people with rehabilitation one month after discharge. Among 300 discharged patients, 146 were discharged to their homes, 154 were transferred to facilities such as nursing homes. The results showed that rehabilitation function that scored using the modified Barthel Index were different according to discharge location. That is, the modified Barthel Index scored greater in home discharged patients than counter group. However, the home discharged patient's physical function and daily activities showed scores that required rehabilitation. Differentiated strategies should be needed for home and facility visit rehabilitation programs for rehabilitated patients.

Estimation of software project cost, effort and duration in the early stage of software development cycle is a difficult and key problem in software engineering. Most of models estimate the development effort using the function point that is measured from the requirement specification. This paper presents optimal team size and duration prediction based on function point in order to provide information that can be used as a guide in selecting the most Practical and productive team size for a software development project. We introduce to productive metrics and cost for decision criteria of ideal team size and duration. The experimental is based on the analysis of 300 development and enhancement software project data. These data sets are divide in two subgroups. One is a development project; the other is a maintenance project. As a result of evaluation by productivity and cost measured criteria in two subgroups, we come to the conclusion that the most successful projects has small teams and minimum duration. Also, I proposed that predictive model for team sire and duration according to function point size based on experimental results. The presented models gives a criteria for necessary team site and duration according to the software size.

There is a strong need to develop a software cost estimation model on economic value perspective. The objective of this research is to improve current software cost estimation method on economic value perspective. We reviewed domestic and foreign researches and practices on software cost estimation with function point method, and derived promising alternative models. Pilot simulation was performed with real project data, and the probable best model was chosen. We collected data from 39 Korean companies, and assesed statistical significance of the model with those data. Empirical data shows that more practical model has better prediction accuracy. That is, the number of input and output modules, the number of tables, and the number of algorithms are chosen to be best set of functions. There exists strong correlation between the calculated function points and project effort. And, the revised set of technical complexity factors and evaluation guidelines show practical usefulness. We suggest that the above result be incorporated in a new improved guideline for software cost estimation. By adopting the results of this research to the guideline, we expect that technology innovation will be expedited, and that overall productivity of software industry will be increased.
