It is common in foreign countries to make a compensative plan for environmental destruction which is caused by development action even in where development is permitted. But, in Korea, environmental plan was regarded as just meeting the legal standard of green area in site development. This study focused on the case of university project, LG village plan, is to evaluate the environment of the site using Hemeroby and suggested restoration plan in compensation for the destructive. The site was a huge development area of apartment located in Suwon. First of all, we evaluated the site using Hemeroby and compared this with LG village plan. Then, we made a compensative plan for the environmental destruction which was not compensated in LG village plan. The results were as follows; $\beta$-/$\alpha$-euhemeroby of the Site was 80.1% before the development and, after the development, $\beta$-/$\alpha$-euhemeroby of the site dropped to 43.7％ and meta-hemeroby increased from 56.3% to 17％. Therefore, we could accept the buildings of LG village development plan and suggested a compensative plan with which we could raise $\beta$-/$\alpha$-euhemeroby like restoring the river, greening parking-lots and rooftops, revegetating cut slope.

The virtual compensator which are realized using a multileaf collimator(MLC) and three-dimensional radiation therapy Planning(3D RTP) system was designed. And the feasibility study of the virtual compensator was done to verify that it can do the function of the conventional compensator properly. As a model for the design of compensator, styrofoam phantom and mini water phantom were prepared to simulate the missing tissue area and the calculated dose distribution was produced through the 3D RTP system. The fluence maps which are basic materials for the design of virtual compensator were produced based on the dose distribution and the MLC leaf sequence file was made for the realization of the produced fluence map. Ma's algorithm were applied to design the MLC leaf sequence and all the design tools were programmed with IDL5.4. To verify the feasibility of the designed virtual compensator, the results of irradiation with or without a virtual compensator were analyzed by comparing the irradiated films inserted into the mini water phantom. The higher dose area produced due to the missing tissue was removed and intended regular dose distribution was achieved when the virtual compensator was applied.

It is so sensitive that the matter of compensation for private possessions caused in the course of public construction planning is very important. Especially, more logical planning is necessary when the dam be constructed, because it is mainly controlled by the surface of water, and if that planning is made public, artificial change is occurred in land use in that area for the purpose of rising the compensation. In this study, the plan for the application of aerial photo based ortho image was drew up for solving these problems and for the rational, rapid compensation. Ortho image was made by aerial photo, used as reading material for the change in land use. The modeling of drainage basin, came under the planning surface of water, and the 3D simulation were performed for the scene analysis, the change understanding in land use for a lot number in a certain period by overlapping the digital image, the digital land registration map, and the digital topography map as well as the analysis of the admitted land followed by the height of reservoir water.

In this study, the physical compensator made with the high density material, Cerrobend, and the electronic compensator realized by the movement of a dynamic multileaf collimator were analyzed in order to verify the properness of a design function in the commercial RTP (radiation treatment planning) system, Eclipse. The CT images of a phantom composed of the regions of five different thickness were acquired and the proper compensator which can make homogeneous dose distribution at the reference depth was designed in the RTP. The frame for the casting of Cerrobend compensator was made with a computerized automatic styrofoam cutting device and the Millennium MLC-120 was used for the electronic compensator. All the dose values and isodose distributions were measured with a radiographic EDR2 film. The deviation of a dose distribution was $\pm0.99 cGy\;and\;\pm1.82cGy$ in each case of a Cerrobend compensator and a electronic compensator compared with a $\pm13.93 cGy$ deviation in an open beam condition. Which showed the proper function of the designed compensators in the view point of a homogeneous dose distribution. When the absolute dose value was analyzed, the Cerrobend compensator showed a $+3.83\%$ error and the electronic compensator showed a $-4.37\%$ error in comparison with a dose value which was calculated in the RTP. These errors can be admtted as an reasonable results that approve the accuracy of the compensator design in the RTP considering the error in the process of the manufacturing of the Cerrobend compensator and the limitation of a film in the absolute dosimetry.

본 논문은 모선가격을 적용하는 계통에서 전력품질기준을 초과한 수용가에 대한 보상을 하는 것이 계통계획상의 의사결정에 어떠한 영향을 주는가에 대한 시험 연구 결과이다. 우리나라는 산업의 고도화에 따라 전력에 대한 산업의 의존 비율이 대폭 증가하였을 뿐만 아니라, 전력품질에 대한 산업체의 요구조건도 과거에 비해 매우 높아졌다. 그러나 현행 계통계획과 전력요금제도에는 이러한 사회적 변화를 반영할 품질에 대한 요소가 포함되어 있지 않으며, 이에 대한 적절한 대비가 되지 않음으로 인한 사회적 비용은 제대로 평가되지 못하고 있다. 본 논문에서는 수용가에 대한 전력요금이 모선별로 할당되는 경우에 각 모선의 전력품질이 측정가능하고 이를 보상비용화 할 수 있다고 가정하는 경우, 이를 계통계획에 반영하였을 때 예상되는 효과를 모의계통을 통하여 시산해보고 그 결과를 토의한 것이다. 그 결과, 전력품질의 비용을 반영한 경우, 전력요금은 상승하지만 전체 비용을 최소화하는 요소설비에 투자하는 방법을 선택함으로써 총괄비용을 감소시키는 효과를 거둘 수 있다.

Most of the cities and countries have distressed themselves about the urban social problem caused by the concentration of industry and population. Especially, disorderly expansion of cities and infrastructure improvement in rapid urbanization have also come into question. For this reason, proven urban planning facilities and tightened regulation on city planning are indispensible to solve these serious problems that we face. There are lots of similar studies to verify how to cope with a rapid urbanization.

Purpose : To reduce the Irradiation dose to the lungs and heart in the case of chest wail irradiation using an oppositional electron beam, we used an Individualized custom bolus, which was precisely designed to compensate for the differences In chest wall thickness. The benefits were evaluated by comparing the normal tissue complication probablilties (NTCPS) and dose statistics both with and without boluses. Materials and Methods : Boluses were made, and their effects evaluated in ten patients treated using the reverse hockey-stick technique. The electron beam energy was determined so as to administer 80% of the irradiation prescription dose to the deepest lung-chest wall border, which was usually located at the internal mammary lymph node chain. An individualized custom bolus was prepared to compensate for a chest wall thinner than the prescription depth by meticulously measuring the chest wall thickness at 1 emf intervals on the planning CT Images. A second planning CT was obtained overlying the individuailzed custom bolus for each patient's chest wall. 3-D treatment planning was peformed using ADAC-Pinnacle$^{3}$ for all patients with and without bolus. NTCPS based on 'the Lyman-Kutcher' model were analyzed and the mean, maximum, minimum doses, V$_{50}$ and V$_{95}$ for 4he heari and lungs were computed. Results .The average NTCPS in the ipsliateral lung showed a statistically significant reduction (p<0.01), from 80.2${\pm}$3.43% to 47.7${\pm}$4.61%, with the use of the individualized custom boluses. The mean lung irradiation dose to the ipsilateral iung was also significantly reduced by about 430 cGy, Trom 2757 cGy to 2,327 cGy (p<0.01). The V$_{50}$ and V$_{95}$ in the ipsilateral lung markedly decreased from the averages of 54.5 and 17.4% to 45.3 and 11.0%, respectively. The V$_{50}$ and V$_{95}$ In the heart also decreased from the averages of 16.8 and 6.1% to 9.8% and 2.2%, respectively. The NTCP In the contralateral lung and the heart were 0%, even for the cases with no bolus because of the small effective mean radiation volume values of 4.4 and 7.1%, respectively Conclusion : The use of an Individualized custom bolus in the radiotherapy of postrnastectorny chest wall reduced the NTCP of the ipsilateral lung by about 24.5 to 40.5%, which can improve the complication free cure probability of breast cancer patients.
