Dwelling environments that can help elderly farmers to live more safely, independently, and conveniently are becoming more and more important. Many rural houses are built without any particular architectural or energy-related criteria, so most of them have poor insulation. The construction technology used is also not precise, which increases the loads for heating and cooling. Therefore, rural houses need to be improved. Also, there is more and more need for plans to realize eco-friendly dwellings, so the principle of nature-oriented plans related to the direction, insulation, or landscaping of a house is being emphasized. Insulation is one of the most effective ways to save energy for heating and cooling. This preliminary study to improve the insulation of rural houses examined three regions in South Korea: the central region, the southern region, and the Jeju Island. A field investigation was conducted on a total of 18 houses, including six from each town in the selected regions. The information was used to figure out the current status of rural houses and the characteristics of the buildings. The main living spaces are the living room for the central region and the main room in the southern region and Jeju Island. The southern regions are plane shapes surrounded by rooms, and all ventilation is accomplished by windows. The studied houses were mostly masonry structures with slate rooftops. Additions and improvements included room expansions and bathroom interior installations.

ASN.1/GDMO is the management object used in network management of TMN(Telecommunication Management of Network). However, ASN.1/GDMO is not directly used for managing the network, but translated Into a language with object-oriented paradigm. Therefore we need a development environment for handling ASN.1/GDMO. In this paper we present an integrated development environment(IDE) which consists of an editor and a browser. A user manages ASN.1/GDMO elements with GUI. The IDE is implemented with FLEX and BYACC in UNIX. And Objectivity DB is used as the DB and Tcl/Tk is used for developing GUI. This paper shows how the integrated environment of ASN.1 and GDMO works, and that it enables to manage efficiently the network.

Purpose: This study was conducted to compare the characteristics of organizational structure and occupational satisfaction among nurses in general hospital and small to medium-sized hospital and to investigate the affecting factors on their occupational satisfaction. Methods: The study was based on the cross-sectional descriptive survey. A self-report questionnaire was used to collect data from 343 nurses between June and July, 2010. Data were analyzed by ${\chi}^2$-test, t-test, ANOVA, Scheffe's test, Pearson's correlation coefficient, and multiple regression using the SPSS/WIN 14.0 program. Results: Hierarchical structure was dominant in general hospital whereas relationship was highly valued in small to medium-sized hospital. Occupational satisfaction was positively correlated with work environment built on relationship, innovation and tasks. Factors significantly influencing on occupational satisfaction in general hospital included innovative work environment, nurses' income and their health status ($R^2$=40.3%). For the small to medium-sized hospital, they included innovative work environment, satisfaction in life, tasks and professionalism ($R^2$=40.4%). Conclusion: Organizational structure, especially innovative work environment and relationship-oriented attitude had a significant influence on nurses' occupational satisfaction. Therefore, nursing administrators have to develop and consider organizational structure to improve occupational satisfaction.

In recent erosion control works, securing not only the disaster prevention space but the environmental space, harmonized with surrounding environment and abundant with biological resources, are emphasized. Inspired of by the fact that efforts to secure such spaces have been being briskly promoted in Japan since the beginning of 1990s', we compile and analyze the Japanese sources about the "environmentally-sound erosion control works" to contribute to the erosion control works of our country. Specifically, in this report, we deal with the subjects of "establishment of the comfortable river environment" and "environmentally-sound erosion control works" which includes "erosion control dam", "water channel works and revetments", "fish routes" and "water quality conservation works".

Recently, the characteristic of plant production systems in Korea has been changed with the strong trends of integration and large scale, using environmental control techniques. To satisfy this change successfully, first of all, the environmental prediction inside the system must be preceded. While many environmental prediction models for plant production system were developed by many persons, each model cannot be applied to the every situation without the perfect understanding of source codes and the technical modification. The purpose of this study is building the environmental prediction model to predict and evaluate the environment inside the system numerically, and also developing the multipurpose program available for practical design. The model consisted of the basic system model, the cultivation related model and the environmental control related model. The contents of each model are as follows : the basic system model is dealing with thermal and light environments, soil environment and ventilation : the cultivation related model with soil and hydroponic cultures ; and the environmental control related model with thermal curtain and heat exchanging system. The environmental prediction model was developed using a common simulation program, PCSMP, so that it could be easily understood and modified by anyone. Finally, the model was executed and verified through comparison between simulated and measured results for soil culture, and both results showed good agreements.

Because of its unique characteristics, the construction industry tends to be affected by economic environment more than any other industries. The domestic construction industry was forced to change its management pattern and system when it went through the foreign currency crisis, and since then, the construction industry has been growing in terms of quality over last 10 years, breaking from the quantitative performance-oriented growth in the past. The study was intended to integrate the financial data of the companies during the period before and after the foreign currency crisis so as to analyze the effect of environmental changes on management performance of the companies. It was aimed at evaluating the changes to the stability, profitability and the growth potential, and collecting the data on variation of the market scale, price of resources such as material and labor and the financial environment, thereby analyzing the correlation with the management performance. The study, to deal with the difficulties which are anticipated, like the foreign currency crisis experienced in the past, was also intended to identify the correlation between the economic conditions and the performance of the construction companies, using the experimental data in the past.

The use of Object-Oriented Distributed Programming(OODP) environment such as DCOM, DSOM, Java RMI, CORBA to implement distributed applications is becoming increasingly popular. However, absence of a fault-tolerance feature in these middleware platforms complicates the design and implementation of reliable distributed object-based applications, although they greatly enhance the quality and reusability of the distributed object-based applications. In this paper, we propose a fault-tolerant programming environment based on RMI, namely Evergreen, for the reliable distributed computing with checkpoints and rollback-recovery mechanism. Based on a series of experiments, we evaluate the performance of Evergreen and find its possibility of extension to fully support our optimal design goal.
