In this study, we tried a study on a direction of the field of oriental medicine on accepting complementary alternative medicine by analyzing the related thesis, journals and papers on the complementary alternative medicine published in the field of oriental medicine. As the result of analyzing the present study of the field of oriental medicine on the complementary alternative medicine, there have been 22 studies on the complementary alternative medicine. Thesis, papers were mainly experimental papers about the bee venom therapy, energy therapy, fasting therapy, and colon therapy, and the journals were actively studied in order of clinical paper, experimental paper, and reference paper about the bee venom therapy, energy therapy, and reflexolgy. The acceptance of complementary alternative medicine by the field of oriental medicine through a scientific relation should be conducted more systemically by setting the main academy taking charge of the study on common characteristics of the complementary alternative medicines on the classification of NCCAM as well as the related academies taking charge of the study on the unique characteristic of each complementary alternative medicine. First, additional studies are needed to make the most of characteristics of each complementary alternative medicine through the main academy and the related academies, and for the next, additional studies are necessary to complement the research trend on each complementary alternative medicine through the main academy and related academies.

A theory-based methodology for describing the thermodynamic properties of molecular nitrogen is presented. The results obtained indicate a successful application of a fully consistent statistical method for the description of a molecular system in different phase states. The method employs a density of states equation for solid nitrogen and a perturbation potential for gaseous and liquid nitrogen. The main characteristics of the calculation method include the need for a minimal number of initial data and the absence of fitting parameters. The adequacy of the physical model that is the basis for the method allows a description of existing experimental data and the peculiarities of the thermodynamic properties.

Due to the lack of fossil fuel the demand for the development of alternative energy is gradually growing. There are solar energy and underground energy as the alternative energies for housing. To use underground energy, we need some data on the underground temperature but the data are very rare in our country. So we need tools to calculate the underground temperature. In this paper a method to calculate the underground temperature is sought with the latitude, the level, and the distance from sea for the district without the measured data.

In this paper, we investigated the alternative sources of limestone. Oyster shell waste originated from aquaculture that causes a major disposal landfill problem in coastal sectors in southeast Korea. Their inadequate disposal causes a significant environmental problems araised. Bio mineralization leads to the formation of oyster shells and consists $CaCO_3$ as a major phase with a small amount of organic matter. It is a good alternative material source instead of natural lime stone. The utilization of oyster shell waste for industrial applications instead of natural limestone is major advantage for conservation of natural limestone. The present work describes the limestone and oyster shells hydraulic activity and chemical composition and characteristics are most similar for utilization of oyster shell waste instead of natural limestone.

Computer simulations were performed for Heating Ventilating and Air-Conditioning (HVAC) systems to figure out more efficient maintenance methods for the building used for adolescent trainees. This study aims at suggesting design alternatives for optimum operation and performing life cycle cost (LCC) for each alternative. First, the capacity of the heat source equipment was determined using annual maximum heating and cooling loads. Annual loads were calculated and applied to the alternative for the purpose of calculating annual energy cost. Second, several types of data were collected to predict energy cost. Finally, the pay back period for each alternative was calculated using total cost estimation during standard duration period. This study indicates that the absorption chiller that does not occupy most part of a mechanical room, and does not need much operation cost was most economical.

Bioenergy can be obtained from various forms of biomass such as agricultural, food processing, and municipal wastes. Recently, its importance is recognized more seriously because of its positive impacts on economic and stable energy supply and environmental sustainability. Despite its advantages, bioenergy has not been used as much as it was expected, nor has it been developed to the level of attractive commercialization in energy market. The main reasons for the sluggish progress have been analyzed by comparing the bioenergy policies in Korea and U.S.A. Both Korea and U.S. governments have recognized the importance of bioenergy and put in various efforts to promote the use of bioenergy. Both governments have legislated alternative energy promotion plans that support R&D, tax reduction, rewards, and low interest loans. However, it is suggested that the bioenergy policy and plan juxtapose the financial supports (R&D, tax exemption, low interest loan, education, etc.) with strong mandates and obligations. Although imposing strong mandates prerequisites the economically attractive and feasible technologies, it can motivate and speed up more effective technology development, in turn. In addition, the bioenergy R&D support must include studies on commercialization and marketing as well as process development. R&D on the socioeconomic effects of bioenergy should also be supported. Lastly, decision making processes for the bioenergy policy, and for alternative energy overall, must include environmental agencies for taking advantage of environmental benefits of bioenergy.
