In this paper, a model of cost evaluatino for computer software development is proposed . This model is designed to cope with various development environment since the development cost is directly dependent on the development environments. The model that satisfies the users request is turned out to be a function point model. For the future research , a model that contain new technique and new development environment and an imaginative model are desired . Also, in order to effective cost estimation a systematic research on structure of software development , establishment of standard development methodology, project management and technique are desired.

PURPOSES : This study aims to examine the differences between the existing traffic demand forecasting method and the traffic demand forecasting method considering future regional development plans and new road construction and expansion plans using a four-step traffic demand forecast for a more objective and sophisticated national highway maintenance. This study ultimately aims to present future pavement deterioration and budget forecasting planning based on the examination. METHODS : This study used the latest data offered by the Korea Transport Data Base (KTDB) as the basic data for demand forecast. The analysis scope was set using the Daejeon Metropolitan City's O/D and network data. This study used a traffic demand program called TransCad, and performed a traffic assignment by vehicle type through the application of a user equilibrium-based multi-class assignment technique. This study forecasted future traffic demand by verifying whether or not a realistic traffic pattern was expressed similarly by undertaking a calibration process. This study performed a life cycle cost analysis based on traffic using the forecasted future demand or existing past pattern, or by assuming the constant traffic demand. The maintenance criteria were decided according to equivalent single axle loads (ESAL). The maintenance period in the concerned section was calculated in this study. This study also computed the maintenance costs using a construction method by applying the maintenance criteria considering the ESAL. The road user costs were calculated by using the user cost calculation logic applied to the Korean Pavement Management System, which is the existing study outcome. RESULTS : This study ascertained that the increase and decrease of traffic occurred in the concerned section according to the future development plans. Furthermore, there were differences from demand forecasting that did not consider the development plans. Realistic and accurate demand forecasting supported an optimized decision making that efficiently assigns maintenance costs, and can be used as very important basic information for maintenance decision making. CONCLUSIONS : Therefore, decision making for a more efficient and sophisticated road management than the method assuming future traffic can be expected to be the same as the existing pattern or steady traffic demand. The reflection of a reliable forecasting of the future traffic demand to life cycle cost analysis (LCCA) can be a very vital factor because many studies are generally performed without considering the future traffic demand or with an analysis through setting a scenario upon LCCA within a pavement management system.

Climate change influences multiple environmental aspects, certain of which are specifically related to agricultural water resources such as water supply, water management, droughts and floods. Understanding the impact of climate change on reservoirs in relation to the passage of time is an important component of water resource management for stable water supply maintenance. Changes on rainfall and hydrologic patterns due to climate change can increases the occurrence of reservoir water shortage and affect the future availability of agricultural water resources. It is a main concern for sustainable development in agricultural water resources management to evaluate adaptation capability of water supply under the future climate conditions. The purpose of this study is to predict the sustainability of agricultural water demand and supply under future climate change by applying an irrigation vulnerability assessment model to investigate evidence of climate change occurrences at a local scale with respect to potential water supply capacity and irrigation water requirement. Thus, it is a recommended practice in the development of water supply management strategies on reservoir operation under climate change.

Purpose - The purpose of this study is to provide a systematic literature review related to environmental upgrading in Global Value Chains (GVCs) and suggest possible future research agendas in advancing environmental upgrading and ultimately GVC boundaries. Research design, data, and methodology - The academic databases such as Science Direct, EBSCO, ProQuest and Google Scholar were explored using a structured keywords searches to identify relevant research in the environmental upgrading area in GVCs. Only relevant papers were selected after reading the abstracts, and analyzed using qualitative content analysis. Results - Overall analysis of the literature review suggests two critical developments in the field of environmental upgrading. The first and foremost major development is an enhanced understanding of environmental upgrading as a concept and phenomenon. The second significant development is that environmental upgrading has been empirically proven to be fundamentally based on relationships and power structures within GVCs. Conclusions - Environmental upgrading in GVCs has been studied individually and not in relation to financial outcomes and social upgrading. Hence, the relationship of environmental upgrading with financial outcomes and social upgrading needs to be investigated. Furthermore, the impact of the interaction of varying institutional structures on environmental upgrading is worthy of future study.

The author discussed present problems and future prospects of psychosomatic medicine in clinical, educational, research, and social aspects. In general, psychosomatic field. particularly. consultation-liaison(C-L) psychiatry in Korea seems to remain on early developmental phase. However, positive change in the general publics' and societal view of psychiatry, specialization of medicine and development of medical technology, implementation of delivery system in medical care could contribute to development of this field. In future, clinically, liaison activity will be more activated. and this field will be developed as main subspecialty of psychiatry. In addition. C-L psychiatry will be subspecialized. and prevention and humanization of medical care could be more emphasized. In education. the main place of education for medical students and psychiatric residents will be changed from closed ward to general ward in which consultation-liaison activity can be performed. In research. consultation liaison model suitable for Koreans will be developed and studies on disease mechanism will be more promoted. In social aspects, this field could influence the general publics' view of psychiatry and change the whole areas of medicine and society toward integration. In order to achieve these goals, medical insurance system and cost relevant to C-L activity should be essentially improved.

This study examined the relationship between ambivalence of Korean working mothers for children and their future desire for child birth. This study examined multiple-role efficacy as a mediator in the relationship between ambivalence for their children and future desire for child birth by Korean working mothers having more than one pre-school aged child. This study examined the mediation effect of multiple-role efficacy on the relationship between ambivalence and desire for child birth by working mothers. On-line and off-line survey data from 291 Korean working mothers with more than one pre-school aged child was used for this study. Collected data were analyzed using the PASW 18.0 program and descriptive statistics analyses. Structural equation modeling and bootstrapping were conducted by AMOS 20.0 program. Results showed that ambivalence for children of working mothers having pre-school aged children had no direct influence on future child birth desire. However, their ambivalence had an indirect influence on future child birth desire through multiple-role efficacy and multiple-role efficacy by working mothers had significant effect on child birth desire. In conclusion, the working mothers' multiple-role efficacy had a mediation influence on the relationship between ambivalence for children and desire of child birth. These results were discussed for designing a policy to counter low birth.
