  • As the energy saving issues become one of the important global agenda, the building simulation method is generally used to predict the inside energy usage to establish the power-saving strategies. To foretell an accurate energy usage of a building, proper and typical weather data are needed. For this reason, typical weather data are fundamental in building energy simulations and among the meteorological factors, the solar irradiation is the most important element. Therefore, preparing solar irradiation is a basic factor. However, there are few places where the horizontal solar radiation in domestic weather stations can be measured, so the prediction of the solar radiation is needed to arrive at typical weather data. In this paper, four solar radiation prediction models were analyzed in terms of their applicability for domestic weather conditions. A total of 12 regions were analyzed to compare the differences of solar irradiation between measurements and the prediction results. The applicability of the solar irradiation prediction model for a certain region was determined by the comparisons. The results were that the Zhang and Huang model showed the highest accuracy (Rad 0.87~0.80) in most of the analyzed regions. The Kasten model which utilizes a simple regression equation exhibited the second-highest accuracy. The Angstrom-Prescott model is easily used, also by employing a plain regression equation Lastly, the Winslow model which is known for predicting global horizontal solar irradiation at any climate regions uses a daily integration equation and showed a low accuracy regarding the domestic climate conditions in Korea.

  • Suitable climate condition is essential for stable growth of crops which directly leads to an increase in crop production. Preceding domestic researches mostly used crop models to predict grain or crop yield in relation to climate change. However, the use of various models and input data based on foreign background lowered the reliability for result. Therefore in this study, we evaluated domestic applicability by comparing and analyzing various crop models developed abroad. In addition, we selected models based on the possibility of acquiring input data and suggested domestic applicability.

  • Among the domestic softwoods, technical value of Pinus koraiensis small diameter logs which have comparatively low applicability was evaluated and sensitive characteristics and physical characteristics were investigated and analyzed for examining if it can be utilized as the interior decoration material. For the sensitive characteristics of Pinus koraiensis, wood figure, wood grain, wood color and odor were evaluated and for the physical characteristics, growth-ring width and latewood percentage, abrasion, density, shrinkage, swelling, absorption, roughness and hardness were evaluated. Then, the possibility to be developed as the interior decoration material was found. As the result of evaluating sensitive characteristics and physical characteristics of domestic Pinus koraiensis, wood figure, wood grain, color and scent clearly were judged to have excellent visual factor as the interior decoration material. And, physical characteristics were also judged to be excellent, so it is judged to be developed as the interior decoration material. Therefore, as the result of various forms of design pattern with domestic Pinus koraiensis small diameter logs, several patterns of interior decoration can be developed by characteristics of each side and colors of heartwood and sapwood. And, in the future, it can be applied to furniture design or interior decoration material for the proper use. Especially, it is considered to contribute to wood applying industry through the study on the quality of domestic small diameter logs which have low applicability.

  • The CISG has been legislated for playing roles as uniform rules which govern international sale of goods. The job of getting unification of the diverse domestic legal systems required almost half century of work. In the process of making the Convention some rules resulted from compromises of nation's relevant interests. The Convention, however, promoted both the legal certainty and harmonization in international trade in that the uniform rules suggest the appropriate resolution to the legal problems in the course of concluding a contract as well as in remedies for breach of contract. This paper focuses systematically on the scope of applicability of the CISG. The Convention deals with contracts for the international sale of goods. However, it does not apply to all kinds of the international sale of goods. The CISG confines the sphere of applicability to a certain type of sales. First of all, the CISG is limited to those contracts having been concluded between a particular group of persons, which is called a personal aspect of applicability. Secondly, the CISG covers a specific category of sales, which is called a material aspect of applicability. Thirdly, the CISG are concluded within a particular period of time, which is called a temporal aspect of applicability. Lastly, the CISG is limited to contracts falling within a given territorial sphere, which is called a territorial aspect of applicability.

  • As an alternative to deep geological disposal technology, which is considered as a reference concept, the domestic applicability of deep borehole disposal technology for high level radioactive waste, including spent fuel, has been preliminarily evaluated. Usually, the environment of deep borehole disposal, at a depth of 3 to 5 km, has more stable geological and geo-hydrological conditions. For this purpose, the characteristics of rock distribution in the domestic area were analyzed and drilling and investigation technologies for deep boreholes with large diameter were evaluated. Based on the results of these analyses, design criteria and requirements for the deep borehole disposal system were reviewed, and preliminary reference concept for a deep borehole disposal system, including disposal container and sealing system meeting the criteria and requirements, was developed. Subsequently, various performance assessments, including thermal stability analysis of the system and simulation of the disposal process, were performed in a 3D graphic disposal environment. With these analysis results, the preliminary evaluation of the domestic applicability of the deep borehole disposal system was performed from various points of view. In summary, due to disposal depth and simplicity, the deep borehole disposal system should bring many safety and economic benefits. However, to reduce uncertainty and to obtain the assent of the regulatory authority, an in-situ demonstration of this technology should be carried out. The current results can be used as input to establish a national high-level radioactive waste management policy. In addition, they may be provided as basic information necessary for stakeholders interested in deep borehole disposal technology.

  • Many organizations need to comply with ISMS-P for information systems and personal information management for ISMS-P certification. Organizations should safeguard vulnerablities to information systems. However, as the kinds of information systems are diversified and the number of information systems increases, management of such vulnerabilities manually accompanies with many difficulties. SCAP is a protocol to manage the vulnerabilities of information system automatically with security standards. In this paper, for the introduction of SCAP in domestic domains we verify the applicability of server-oriented system which is one of ISMS-P certification targets. For SCAP applicability, For obtaining this goal, we analyze the structures and functions of SCAP. Then we propose schemes to check vulnerabilities of the server-oriented system. Finally, we implement the proposed schemes with SCAP to show the applicability of SCAP for verifying vulnerabilities of the server-oriented system.
