National Knowledge and Information Resources of KADO(Korea Agency for Digital Opportunity and Promotion) were distributed to the several data centers. The metadata for the resources was the conceptual level recommended standard. It was not for the integration, but the retrieval. So it is not easy to integrate to the central metadata DB or connect metadata among the data centers. In this paper, we analysed the metadata of the several data centers and provided the integrated standard model for the central metadata DB.

The relationship between areal total phosphorus(TP) and areal hydraulic loading was identified and used as defining the trophic state of the reservoir. And three simple, conceptual TP models were tested against the measured in-reservoir TP concentration. The analyses were based on water quality data measured in the Ki Heung reservoir for two years. The results showed that Ki Heung reservoir has undergone eutrophic state, and Dillon's and Vollenweider's TP models were in close agreement with the measured annual mean TP concentration. However, the OECD's model understimated the measured annual mean TP concentration in the Ki Heung reservor. A discussion is given for the hypothetical application of TP loading plot which might be useful for establishing the TP control program in the resavoirs/lakes.

Architectural design work depends on information made from earlier phases such as feasibility study, planning, and conceptual design. This design guideline information includes design objectives, requirements, and constraints made by decision-making, and has great influence on various works of latter phases of design process. Despite of this cognition, however, the lack of design guideline information management still remains as one among the critical issues in design area. Design tools with design guideline information do not also address the issue of interoperability throughout the life-cycle of buildings. The purpose of this research is to propose a method for design guideline information management by using the IFC technology and IFC Property set (Pset) extension mechanism. The method comprises defining and mapping the practically used design guideline items and extensible IFC data model, and includes the management of relationships that exist between design guideline information and design model in the IFC data model.

The design of agricultural facilities is the consistent activities, which systematically analyze all the actual conditions, design the unit structures, and improve the faming environment through efficient organization of the unit facility. The design of agricultural facilities is composed of site study, preliminary design, primary design, and detail design. Integrated design system can manage and process the information created by and used in all steps of design process. Formal data models of these design activities are important conceptual steps in development of integrated design system. However, most of existing models are not available for agricultural facilities. To support efficiently developing the integrated design system of agricultural facilities, we have developed the Multi-Layered Primitive-Composite mode I through object-oriented analysis of agricultural facilities. The MPC model not only satisfies the characteristics of agricultural facility, such as variety, coupling, informal data, but also improves abilities of integrated design system such as extensibility, flexibility, and granularity. The paper presents a formal definition of the MPC model.

Purpose : The purpose of this study was to develop and apply a Core Skill-TLP(Core Skill-Tutorial, Laboratory, Practicum) package in Patient Management and to effect of core skill-TLP education. Methods : This study was used to developed Patient Management' Core Skill-TLP package throughout 14 steps of Core Skill-TLP package development model. Then, Core Skill-TLP Learning methodology was implemented in first year student in the undergraduate emergency medical technology, and survey was done. Results : 1. Core Skill-TLP package model was presented based on conceptual model of PBL(S-PBL). 2, The student in OSCE did significantly better in clinical patient management core skills performance. 3. As to the satisfaction of Core Skill-TLP package management, student, tutor and self-satisfaction score was 3.21, 3.42, 3.38 respectively. Conclusion : This study was suggested that Core Skill-TLP education would be necessary with well-structured package and achieved advantage of simulation and PBL.

This study assessed scuba divers' wetsuit selection criteria based on the gender, age and scuba diving commitment level along with identifying currently owned and preferred wetsuit types. Lamb and Kallal's Functional, Expressive, and Aesthetic Consumer Needs (FEA) Model was the conceptual framework used for this study. Scuba diving has seen consistent growth, worldwide, it is necessary to investigate with wetsuit needs of this consumer group. A survey of 302 active scuba divers participated in the study. Total participants included 202 male and 100 female scuba divers. Divers stated fit was the most highly rated criteria with don/doff being most problematic. Female and older divers regarded functional performance criterion greatly(p<.05). Highly committed divers regarded the functional quality (p<.01) and aesthetic/expressive features (p<.05) of the wetsuit as important and owned more wetsuits(p<.01). Gender saw differences in required sizes ranges(p<.001) and style preferences(p<.05). Results suggest gender, age, and commitment levels all impact the wetsuit selection criteria of scuba divers.

Soil erosion due to climate change is one of the global environmental issues. Especially, Korea is vulnerable to soil erosion as the frequency of extreme rainfall events and rainfall intensity are increasing. Soil erosion causes various problems such as reduced farmlands, deterioration of water quality in rivers, etc. To these severe problems, understanding the process of soil erosion is the first process. Then, it is necessary to quantify and analyze soil ersoion using an erosion model. Soil erosion models are divided into empirical, conceptual, and physics-based models according to the structures and characteristics of models. This study used GSSHA (Gridded Surface Subsurface Hydrologic Analysis), the physics-based erosion model, running on WMS (Watershed Modeling System) to analyze soil erosion vulnerability of the CheonCheon watershed. In addition, we compared the six sediment transport capacity formulas provided in the model and evaluated the equations fir on this study site. Therefore, this result can be as a primary tool for soil conservation management.

The cyberspace, which is the fifth battle field, should be utilized for multi-domain maneuvering between the cyberspace and the physical space using an electromagnetic spectrum. This becomes a major concept of cyber electronic warfare that combines the characteristics of cyber warfare and electronic warfare. In this study, the concept of cyber electronic warfare is analyzed by using the OSI reference model and examining the threats of the two-layer data link layer.

Vegetation processes have a significant impact on rainfall runoff processes through evapotranspiration control, but are rarely considered in the conceptual lumped hydrological model. This study evaluated the model performance of the Hapcheon Dam watershed by integrating the ecological module expressing the leaf area index data sensed remotely from the satellite into the hydrological partition module. The proposed eco-hydrological model has three main features to better represent the eco-hydrological process in humid regions. 1) The growth rate of vegetation is constrained by water shortage stress in the watershed. 2) The maximum growth of vegetation is limited by the energy of the watershed climate. 3) The interaction of vegetation and aquifers is reflected. The proposed model simultaneously simulates hydrologic components and vegetation dynamics of watershed scale. The following findings were found from the validation results using the model parameters estimated by the SCEM algorithm. 1) Estimating the parameters of the eco-hydrological model using the leaf area index and streamflow data can predict the streamflow with similar accuracy and robustness to the hydrological model without the ecological module. 2) Using the remotely sensed leaf area index without filtering as input data is not helpful in estimating streamflow. 3) The integrated eco-hydrological model can provide an excellent estimate of the seasonal variability of the leaf area index.
