No matter what Corporate Social Responsibility has been discussed, that has been indifferent. But, new concept of Corporate Social Responsibility, Socially Responsible Investment is attracted recently and these come to the front with management strategy or policy in 2004. Corporate Social Responsibility is progressing toward direction of standardization over dimension of simple discussion. Continuance possibility Management is gathering strength by supplement method that limitation of Environment Management and Ethics Management are emphasized. How does corporation cope with change of business environment?

Mild combustion or Flameless oxidation(FLOX) have been considered as one of the most prospective clean-combustion technologies to meet both the targets of high process efficiency and low pollutant emissions. A mild combustor with high air preheating and strong internal exhaust gas recirculation is characterized by relatively low flame temperature, low NOx emissions, no visible flame and no sound. In this study, the Steady Flamelet Approach has been applied to numerically analyze the combustion processes and NOx formation in the mild combustor. The detailed discussion has been made f3r the basic characteristics of mild combustor, numerical results and limitation of the present combustion modeling.

In order to set up the optimal required capabilities to satisfy a variety of domestic and foreign demands for the Tilt-rotor UAV, MOE(Measure of Effectiveness) hierarchy was designed through an expert discussion, and the weight of the MOE was determined by utilizing AHP method. The independent MOE assessment on the required capabilities was accomplished for the current configuration, available alternatives and foreign competitive UAVs. Finally the cost-effectiveness for the alternative and competition UAV was analyzed.

While making a vigorous discussion about self-regulation for exponential growth of harmful health information on the Internet, many countries lave made various efforts to select and circulate high quality health information on the Internet. The purpose of this study Is to review the serf-regulation methods of health information on the Internet and to suggest quality control methods of health information on the Internet suitable for Korea. Self-regulation methods of the health information on the Internet include ‘content rating system(or content selection system)’, ‘codes of conduct or guideline’, ‘internet hot-line’, ‘education for information providers and consumers’. Any self-regulation method should be used with other methods. We can regulate health information on the Internet effectively by using both self-regulation methods and compulsive methods such as law. Also information providers, information consumers, specialists, consumer representatives, scholars, governments officers should take part in doing these efforts and make concern.

This is a brief review and discussion for present status and prospects of quality evaluation in medicinal plants as oriental medicine materials (OMM). Quality in medicinal plants could be defined as the combination of origin, external appearance, effectiveness and safety, and be evaluated by plant taxonomic, morphological, physiochemical and biological methods. For high-quality improvement and standardization of OMM, medicinal plants should be produced through using proper species or good variety and standard cultivation method in suitable cultivation area. Standardizing of quality means to meet with minimum qualifying criteria of OMM in the market while improving of quality to be over standard quality of medicinal piano in production. For making new high quality and standardized products, we need to keep standard field plants, standard OMM, standard plant specimen, and standard compounds. Researchers and administration have to study and propose the quality factors and their evaluating techniques and criteria, so high-quality and standardized produce of medicinal plane could be produced and distributed under the control of the relevant regulations, and would be contributed to increasing of national health.

A low speed wind tunnel test for the canard airplane model was conducted in KARI LSWT. To measure the required level of accuracy, the image system was applied for all elevator deflection and different canard incidence conditions. By doing so, the difference in aerodynamic characteristics between the forward swept and straight canards can be precisely evaluated, and the pros and cons of both canards arrangements can be discussed. Compared with both canard configurations at the same incidence angle setting, the straight canard has benefits in lift and drag, and the slope of pitching moment increases more moderately than the forward swept canard. The listed data and discussion would be useful to whom wants to design a canard airplane.

In this study, the thermodynamic and magnetic properties of alloying element substituted B2 FeAl systems have been investigated using the all-electron FLAPW method based on the GGA. It was shown that the important changes take place in the structural properties as well as in the magnetism when alloying element is substituted by Fe or Al site in B2 FeAl. Detailed discussion on the thermodynamic and magnetic properties and electronic structure of these intermetallic compounds will be given.

The purpose of this study is to suggest the solutions for policy related to estimating the household work to be set up. In this study the damages to housewife are compared in the viewpoints of the insurance company and the victim. And this study criticizes the unfairness in judging wife's contribution to matrimonial property in case of divorce. So for the future studies decisions to the concept of housewife the survey method for time-use data and the substitute wage are needed. And for setting up the policy continuous and objective discussion about the matter interest of the parties concerned and consensus of public opinion and the reform of image about the family nd household work are needed.

Hybrid propulsion systems provide many advantages in terms of stable operation and safety. However, classical hybrid rocket motors have lower fuel regression rate and combustion efficiency compared to solid propellant rocket motor. The recent research efforts are focused on the improvement of volume limitation and regression rate in the hybrid rocket engine. The present study has numerically investigated the combustion processes in the hybrid rocket engine. The turbulent combustion is represented by the eddy breakup model and Hiroyasu and Nagle and Strickland-Constable model are used for soot formation and soot oxidation. Radiative heat transfer is modeled by finite volume method. To reduce the uncertainties for convective heat transfer near solid fuel surface having strong blowing effect, the Low Reynolds number k-$\varepsilon$ turbulent model is employed. Based on numerical results, the detailed discussion has been made for the turbulent combustion processes in the vortex hybrid rocket engine.

National curriculum for environmental education recommends various teaching-learning methods including survey and discussion of environmental problems, investigation of case studies, experiments, role play, and field-experience learning in addition to the traditional lecture-oriented teaching methods. The field experience learning in environmental education is considered to be a good method to develop environmentally sound attitude and to cultivate environmental sensitivity, but here has been very limited research concerning models for field-experience learning. The aim of this study is to develop a model of the field-experience learning program of environmental education utilizing environmental facilities. In this study a kind of such a basic model was developed and presented. The developed basic model of the field-experience learning was applied to the case utilizing landfill facilities. A specific application of the landfill program to the Bangcheon-ri landfill, in Daegu, was also presented with related teaching materials developed in this studies. And various aspects in the program was discussed.
