Since ubiquitous embedded software is sensitive to the resources and environment of target system, it should be debugged in the same environment as actual target system. However, existing tools to debug embedded software, in which access to internal signal or resources is limited, are uneconomical. In the thesis, economical and practical USB-JTAG Adapter that can use open GDB is suggested. It can remove existing limitations of environment implementation that have many difficulties in implementing an environment for remote debugging. Hence, the thesis provides economical interfacing environment that can debug ubiquitous embedded software inside remote system.

In the software industry of Korean Small and Medium-sized Enterprise(SME)s, the development process is often not mature. This may lead to failures in quality control and output management. As a result, the quality of the software can be degraded. To solve the problem, the software visualization technique, which is from the National IT Industry Promotion Agency Software Engineering Center can be applied. We have experienced with mentoring not only the visualization of software development process, but also various visualization process of SMEs. However, the existing software visualization method was difficult to install environment and its time cost was high. This paper proposes a software visualization environment through a cloud service along with a case of building a software visualization environment. We expect that this method will make it easier to build a visualization environment and improve the quality of SME software.

The purpose of this study is to evaluate the residential environment by indicators of internal and external conditions of Purchased Rental Housings (PRH). In this study, we conducted a field survey on 200 units of PRH to evaluate the residental environment located in Seoul, Incehon, Kyounggi, Daejeon, Busan and Daegu. As a result, the residential environment of PRH is managed as above average at most indicators. Partly parking areas and fire-fighting facilities are need to be improved for safety and health. It is considered that the political goal of PRH, such as housing safety and stability for low-income class, is achieved by decent housings and appropriate maintenance. However, it is still necessary to improve its management system for sustainable and safe residential environments.

A combined watershed and receiving waterbody model was developed for operational water flow forecasting of the Nakdong river. The Hydrological Simulation Program Fortran (HSPF) was used for simulating the flow rates at major tributaries. To simulate the flow dynamics in the main stream, a three-dimensional hydrodynamic model, EFDC was used with the inputs derived from the HSPF simulation. The combined models were calibrated and verified using the data measured under different hydrometeological and hydraulic conditions. The model results were generally in good agreement with the field measurements in both calibration and verification. The 7-days forecasting performance of water flows in the Nakdong river was satisfying compared with model calibration results. The forecasting results suggested that the water flow forecasting errors were primarily attributed to the uncertainties of the models, numerical weather prediction, and water release at the hydraulic structures such as upstream dams and weirs. From the results, it is concluded that the combined watershed-waterbody model could successfully simulate the water flows in the Nakdong river. Also, it is suggested that integrating real-time data and information of dam/weir operation plans into model simulation would be essential to improve forecasting reliability.

The purpose of this study was to investigate and analyze how reading activities related to the environment of third grade students at elementary schools affect their attitude on the environment. A survey was carried out on 73 third grade students in K elementary school located in Buk-gu, Daegu metropolitan city. The students were divided into an experimental group and a control group. A preliminary inspection with a check paper on environment -related attitude was performed. Then the students in the experimental group performed a reading activity connected with the environment for eight weeks, and a comparative analysis of the results of posttest was conducted. As a result of the study, the posttest of the experimental group in its overall attitude toward the environment and change in attitude by areas, subjects, gender, showed high statistical significance. In terms of effects by areas, each of the three areas progressed evenly as a whole, although emotion showed the most improvement among them. In consequence of the effect by subjects, all subjects improved positively, although the environmental pollution and recycling parts showed the biggest change. Therefore, elementary third graders' reading activities related to the environment was more likely to change their attitude toward the environment to a more desirable direction. Hence, when the proper data for this activity is put into environment-related classes according to the aim of a lesson, it seems that students' attitude toward environment can be improved and moved into a desirable direction. Moreover, hopefully their environmental consciousness and practical inclination will grow when it is sustained even in ordinary times.

There are differences in method and cycle of flow rate survey depending on purpose of the operating department. To verify and use results of flow data according to the purpose, flow data of the directly measured and tele monitoring system were compared to verify validity. Flow measurement in the Ministry of Environment is aimed at setting up a standard flow of target water quality for water quality management and securing flow data of low and normal water level seasons for water quality evaluation. In this study, correlation analysis result ($R^2$) of same time zone data by direct measurement and tele monitoring system (TMS) at Seombon D point, a unit watershed of Seomjin river, for six years ('10 ~ '15) according to implementation of Total Daily Maximum Load (TDML) was wading 0.716, boating 0.962 and on bridge 0.943, and effectiveness of measurement method was verified by characteristics of flow duration as a season of dry and low-water; normal and high water are appropriate for wading, boating, and on bridge respectively. Results revealed it is reasonable to use directly measured results using the wading and boating method for low water level and dry seasons, and TMS data for rainy seasons. It can be used important data for future policy decisions.

Nutrient (i.e., nitrogen and phosphorus) budgets are required under a 'Livestock Excreta Survey'. A nutrient budget is one of the agri-environmental indicators that calculates the difference between the inputs and outputs of the amount of nutrients within a certain boundary and for a certain time period (e.g., 1 year). In this study, a nutrients budget model was developed to effectively determine the surplus of nutrients within a region in Korea. The C# program language was used in order to facilitate the deployment of a graphical user interface (GUI) and to enhance compatibility. Also, the model was developed on Windows OS, which is the commonly used operating system in Korea. The model was based on the OECD/Eurostat nutrient budget method, and it was modified to consider manure composting procedures as well. There are key features of the nutrient budget model, including directly use of the original data sets from various input and output sources, and a collectively exchange of the address in different formats. The model can quickly show the results of various spatial and temporal resolutions with the same data, as well as perform a sensitivity analysis with coefficients and easily compareresults using tables and graphs. Further, it would be necessary to study the extension of the scope of utilization, such as the application of various nutrient budget methods. It would also be helpful to investigate both pre and postprocessing information such as linking input data through online systems.

In conventional game systems, virtual environments usually have just the role of a background without the direct relationships for game characters. nev do not consider the semantics about virtual environments. In this paper, we develop a game navigation system that provides semantic information about virtual environments including geographical, historical or my other location-dependent information. Then, the game character obtains the geographical location and its related information when it navigates through a virtual environment. It can be an implementation method for a semantic virtual environment because it can have the environment maintain its semantics depending on the specific location. In addition, we describe a method that can control a character's motion in the semantic virtual environment interactively, and that can input specific information according to the location of the character.
