A analysis of environmental text book for secondary education has been conducted toward ecocentric education, eventually to provide a creative and open-minded teaching. Based on the result of analysis, the following problems suggested, the content of the text book has too wide scope for the intelligence of the middle school student. Furthermore, the text book is mainly focused on demonstrating the surface of the phenomena as an existing public nuisance in society, however, the present book deals with the superficial aspects of environmental problems and makes the problems considered as simple. From the analysis study of present environmental text book several suggestion has been conducted as follows : First, additional education units are needed for judgement traning toward emotional approach to law of nature and environmental phenomena. Second, it is necessary for teachers to develop various teaching methods in an environmental class.

The numerical simulation of non-reactive turbulent model and cold flow experiment were carried out to propose the incinerator type for the domestic refuses and to investigate the design factor and operating conditions. The "standard stoker incinerator" proposed in this study was modified from central flow type with carrying out by material and numerical simulations repeatedly. The stoker has the characteristics of good mixing between refuse and hot combustion gas in primary combustion chamber and between unburned gas inflowing and secondary air jet in secondary chamber. Also there was no recirculation zone in secondary chamber so that mixing time was increased with higher residence time. Therefore this incinerator could be possible for domestic refuse to burn up with the low emission and high efficiency combustion. Parametric screening studies were achieved in standard stoker incinerator. The parameters are stoker type, secondary air inflow type, secondary air injection angles, secondary injection air flow rate and primary air inflow rate. The results are as follows; 1. In the same conditions with standard stoker incinerator, flow pattern was not almost changed by changing inclined stoker type. 2. The injection potion and angle of secondary air had an effect on flow field in secondary combustion chamber. 3. Flow pattern was not almost changed with the variation of the flow rate of primary and secondary air injection. The results of parametric studies said that the main factors for the design are the incinerator configuration of secondary combustion chamber and/or the position and angle of secondary air injection.

This study was performed to improve the methods for elementary education to save energy and preserve the environment. To obtain lots of data, domestic and foreign references and articles which are related to the education for the environmental preservation were analyzed. At the same time, the curriculum and the present situation of the elementary education were also studied. From these studies, several suggestions were proposed. First, a number of stories and animations relating to save energy and preserve the environment should be contained in the curriculum. The curriculums containing the above contents were only Natural Science, Social Studies, and Practical Course. However, the composition was very simple and was not systematic. Second, lots of references and textbooks were required to teach and study the environmental situation. The elementary schools only had several student textbooks, and the teachers also had several video tapes recorded from television. Third, several practical education should be reinforced to make a new life style for saving energy. Only a limited number of posters and television programs explaining environmental problems were given to the students, and practical motivations to make a real life pattern were not prepared so far. Fourth, the environmental education in the school should be closely related to home education. To obtain maximum effect, the home education was absolutely required because home is the best place to practice a good life style to save energy and preserve the environment.

Human beings are destined to die. After death, the dead body should be taken care of through various procedures by the environments of the region, ideology, cultural custom and the dead's social standing. The cemetery systemt can be classified into two large groups. One is the Burial in Wet-Condition, there are MAE-JANG, the Burial in the earth and SU-JANG, the Burial in the sea. And the other is in Dry-Condition, there are HWA-JANG, cremation by the fire and PUNG-JANG, the dealing by the wind and CHO-JANG, the dealing by the eagle. The grave site system in our contury must be changed to collectivization of scattered grave site, limiting burial time, making the list of the graves, getting rid of neglected graves. The cremation system must be supplemented by a certain ritual to give the surviving family comfort and compensation. The facilities of a crematory must be changed into more high-qualified one to win the people's trust, The remains of the dead can be scattered, laid in a charnel house or in Napkol-t'ap, Yo˘ng-t'ap, So˘k-ch'ong. A cemetery-system-improvement-plan requires strong promotion from national leaders, active educational movement from religious leaders, an effort to change people's idea and a recognition of the problems among the policy makers.

環境權理論의 再檢討

金春換 조선대학교 환경공해연구소 2001 環境公害硏究 Vol.17 No.1

We can't survive even one day without air, water and sun etc., because they give a big effect on our normal life. But we have destroyed nature resources to produce daily necessaries. These days we start to feel the necessity of protecting and preserving environment as long as their destruction is threatening to our life. In order to protect environmental destruction, we have started to regulate private ownership by law. We call it the private theory of environmental right. But we can't basically protect and preserve nature resources by the theory of private environmental right. So I urge in this paper that we should accept the public trust doctrine into our law to preserve and protect natural environment. The theory means that submerged and submersible lands are preserved for public use in navigation, fishing, and recreation and state as trustee for the people, bears responsibility of preserving and protecting the right of the public to the use of the waters for those purposes. We can resolve the complicated environmental problems by the theory, because it means any civil and environmental group as well as aggrieved persons can sue against the state or local government. The writing order of my paper is as follows: Section 1 of this Article will present an aim to study and problems to resolve the today's environmental right. Section 2 of this Article will reconsider the basic theory over environmental right in constitutional law. Section 3 of this Article will reconsider the problem of environmental right. Section 4 of this Article will adapt the public trust doctrine into Korean law. Section 5 of this Article as a conclusion will arrange an essential points, and present some assignments to resolve in the future after accepting the public trust doctrine into Korean law.

The results are as follows ; 1. It is necessary to improve the appraisal system for how radiation environmental impact assessment in the preparatory stage, when the nuclear power plant is under construction. The administrative agency should take the charge of making out the evaluation of the influence of radiation and be able to gather not only the opinions of civil environmental entities. It should read just system to observe the content of the environmental impact assessment. 2. Of course the neighboring residents are at odds with the mobilized construction crew due to the bad effects of noise, vibration, dust and so on during construction and they are concerned about their health due to accumulated bad effect. Consequently, we need to analyze whether we should keep to a strict the level of radiation discharge or not. 3. The atomic waste does not come under the rule of waste countrol but of atomic energy control. Due to the insufficiency of regulations about the safty of atomic waste and proper management, it is necessary to have stricter atomic waste control administration. 4. There are no regulations on heat pollution under our environmental law at this time. Therefore, we need legislation about heat pollution incruding the matter of discharge water from an nuclear power plant. 5. Countermeasure are necessary for closed-down nuclear reactors. Technical know-how concerning this is not sufficient on the international level. Related legislation is also need.

It is well known that unburned hydrocarbons are abundantly emitted into the atmosphere at cold start in 81 engine. Many nations tend to enforce regulations of emission much more strictly. This study was conducted to develop a system which reduces HC emissions at cold start using the device of temporary storage and recombustion after analyzing the emission characteristics of hydrocarbons during the cold start. The exhaust gas measurements are focused upon the first 30 seconds of operation after starting, with the engine and coolant initially at ambient temperature because this period has a major effect on HC emissions, over the FTP cycle. The engine examined is a 4-cylinder. 16-valve SI engine. K type thermocouples attached on the O_(2) sensor, the catalytic converter and the coolant, and each sensor for the engine were connected to the A/D board to find the parameters for storage time and recombustion mode. The emissions were initially enriched in light fuel alkanes and depleted in heavy aromatic species, It was decided that the maximum storage time was 30 seconds at cold start. The time for storage was decreased with warmed start because the O_(2) sensor's conversion at warmed start is much faster than that at cold start. The recombustion mode was selected by using the rate of throttle valve, engine speed, and operation conditions of purge solenoid valve to avoid engine torque fluctuation.

A major source of the hazardous waste generated is from chemical industries producing plastics, herbicides, pesticides and chlorinated solvents. All of these processes produce a class of hazardous waste termed the chlorinated hydrocarbons(CHCs), either directly or from undesirable side reactions. Generally, hazardous waste is physical characteristics of difficult destruction at high temperature. We investigated the destruction characteristics of hazardous waste through incineration. A nonequilibrium combustion model was used to describe the effect of the chemical kinetics due to the flame inhibition characteristics of CCU which was used as the surrogate of hazardous waste. In this study, the numerical simulation data for 3-dimensional dump combustor shows a quantitative good agreement with experimental data. Also dump incinerator shows high destruction efficience of CCl_(4). And parametric screening studies was carried out through numerical simulation with changed CCl_(4)/C_(3)H_(8) ratio, waste injection velocity and waste equilibrium ratio.
