ln competitive electricity market, useful technique would be required to calculate settlement amount for electric power traded between market participants and KPX since a number of market partici-pants would appear and trade electric power. Especially calculation of constrained on/off compensation amount can be complicated, and needs to be understood clearly by market participants to avoid unnecessary disputes. This paper presents a technique to settle more easily constrained on/off compensation amount using surplus function. In this technique, a surplus is calculated by each dispatched values and then the compen-sation amount is calculated by the difference of each surpluses. By doing this, settlement amount can be cal-culated by summing the trading amount and the compensation amount.

매년 증가하는 수요에 맞추어 원활하게 전력을 공급하기 위해서는 발전력 증대, 송전선로 건설 등의 유효전력 공급설비 확충 뿐만아니라 적정한 전압보상 설비가 필요하다. 이에따라 한국전력공사에서는 전력계통의 적정전압유 지를 위한 정전콘덴서 설치계획을 매년 수립 시행해오고 있다. 그러나, 최근의 전력산업 구조개편에 의한 계통운영여건 변화, 수도권의 발전력대비 수요 점유비의 지속 증가 등 무효전력 수급관련 주변여건의 변화로 보다 정밀한 계획수립에 대한 요구가 심화되고 있다. 예년의 정전콘덴서 설치계획 수립이 단순히 적정전압유지를 위한 소극적 차원에서 이루어졌다면 근래의 계획은 전력계통 의 전압안정도 확보는 물론 계통제약 최소화까지 고려되는 적극적인 방향으로 변화되고 있다. 본 고에서는 이렇게 다양화되고 있는 여건 변화에 부응하기위해 필요한 무효전력설비 계획관련 방법론 고찰과 이를 토대로 검토된 2003년 우리나라 계통 적용사례를 다루었다.

The purpose of this study is to find out the methodologies, using GIS techniques, to appraise the parcel prices and to estimate the compensation expenditures according to road expansions. This study consists of 2 parts. The first pare is to find out the ways for appraisal of patrol prices in certain area by the publicly announced land prices. The second part is to estimate the differences of compensation expenditures according to road expansion methods. The conclusions are as follows. First, to appraise the target parcel prices, a comparison to the publicly announced land prices should be used. For this, 19 items of land characteristics of existing land information should be analyzed and compared using GIS techniques. Second, the compensation expenditure could be easily estimated using GIS techniques too. In this process, if necessary, we have to apply the minimum parcel size in Building Codes.

통신망간 상호접속료 산정 방식으로 장기증분비용방식이 확산되고 있는 가운데 국내에서도 2004년 이후 시내, 시외, 공중 및 이동전화망의 접속료는 장기증분비용방식이 적용될 계획으로 있다. 2002년 12월 개정 전기통신설비의 상호접속기준 22조의4의 장기증분비용 방식을 적용함에 있어 유선망은 각국에서 선행연구가 진행되어 왔고 실제 적용사례도 많기 때문에 비교적 사업자간 합의점을 찾기 용이한 측면이 있으나 이동망의 경우 선행연구가 부족하기 때문에 원가범위를 둘러싼 당사자간 논란의 여지가 많은 실정이다. 특히 현행 접속료 산정기준에서 유선의 경우 가입자선로가 착신원가 범위에서 제외되고 있는 반면에 이동망의 경우 가입자접속(access) 비용이 착신접속원가에 포함되고 있어서 향후 LRIC 방식 적용시 이동망의 가입자 접속구간 비용을 착신증분원가 산정 범위에 포함한 것이지 여부를 가지고 논란이 예상된다. 본 고에는 미국의 이동망 착신보상 규제 및 판결사례를 살펴봄으로써 앞으로 개발될 이동망 LRIC 방식 비용산정시 액세스 비용에 관한 원칙을 정하는데 시사점을 제공하고자 한다.

Purpose: In Asan Medical Center, Two parallel opposite beams are employed for total body irradiation. Patients are required to be in supine position where two arms are attached to mid axillary line. Normally, physical compensators are required to compensate the large dose difference for different parts of body due to the different thicknesses compared to the umbilicus separation. There was the maximum dose difference up to 30% in lung and chest wall compared to the prescription dose. In order to resolve the dose discrepancy occurring on different body regions, the feasibility of using Fieid-in-Field Technique is investigated in this study. Materials and Methods: CT scan was performed to The RANDO Phantom with fabricated two arms and sent to Eclipse treatment planning system (version 10.0, Varian, USA). Conventional plan with physical lead compensator and new plan using Field-in-Field Technique were established on TPS. AAA (Anisotropic Analytical Algorithm) dose calculation algorithm was employed for two parallel opposite beams attenuation. Results: The dose difference between two methods was compared with the prescription dose. The dose distribution of chest and anterior chest wall uncovered by patient arms was 114~124% for physical lead compensator while Field-in-Field Technique gave 106~107% of the dose distribution. In-vivo dosimetry result using TLD showed that the dose distribution to the same region was 110~117% for conventional physical compensator and 104~107% for Field-in-Field Technique. Conclusion: In this study, the feasibility of using FIF technique has been investigated with fabricated arms attached Rando phantom. The dose difference was up to 17% due to the attached arms. It is shown that the dose homogeneity is within ${\pm}10%$ with the CT based 3-dimensional 4 step FIF technique. The in-vivo dosimetry result using TLD was showed that 95~107% dose distribution compared to prescription dose. It is considered that CT based 3-dimensional Field-in-Field Technique for the total body irradiation gives much homogeneous dose distribution for different body parts than the conventional physical compensator method and might be useful to evaluate the dose on each part of patient body.

진상용 콘덴서를 설치하여 항상 높은 역률을 유지하고 전기설비를 효율적으로 이용하려면 부하의 변동에 맞추어 필요한 진상 용량만 공급하도록 콘덴서를 개폐 제어해야 한다. 수동 조작으로 제어하기 때문에 비현실적인 경우가 많다.또한 전원측과 보상으로 인한 손실 증대를 막기 위해 공장설비에는 콘덴서 자동제어방식이 많이 있으며 건축 전기설비의 경우도 건물의 용도와 규모에 따라 적절한 제어 방식이 적용되고 있다.

In general, orthodontists make problem lists and treatment plans based on norms of several cephalometric standards. But consideration of dentoalveolar compensation, which tends to maintain normal dental arch relationship in various skeletal jaw relationships, helps orthodontists make more individualized treatment objectives and plans. The purpose of this study was to classify skeletal patterns of normal occlusion samples by cluster analysis and to investigate the dentoalveolar compensation according to skeletal patterns. The subjects were consisted of 125 subjects who were normal occlusion samples at Seoul National University Dental Hospital, Department of Orthodontics. Lateral cephalograms in centric occlusion were traced and digitized. The skeletal patterns of normal occlusion samples were classified into three horizontal groups and three vertical groups by cluster analysis and ANOVA on the skeletal and dentoalveolar measurements among the groups were carried out. The results were as follows ; 1. Anteroposterior and vertical skeletal relationships of normal occlusion samples were very variable. 2. As the mandibular position was anterior to the maxilla, the maxillary incisors inclined more labially, the mandibular incisors more lingually, and the occlusal plane was flattened due to the anteroposterior dentoalveolar compensation. dentoalveolar height was decreased and upper posterior teeth was uprighted to the palatal plane and lower incisors and lower posterior teeth to the mandibular plane. 4. Lower incisors were more strongly associated with the dentoalveolar compensation than upper incisors according to the anteroposterior and vertical skeletal relationship.

원자력 발전 계획에 채택은 현대적인 경영 및 산업상의 개념에서 얻을 수 있는 이점을 누릴 기회가 되는 것이므로 이러한 개념들은 발전소의 계획설계 제 허가 및 건설공사의 제반 과정에서 적용시킬 수가 있는 것이다. 따라서 이러한 현대적 개념의 적용 대상인 원자력발전소와 다른 공업제품에서 이 두가지 사이의 중요한 차이점은 1. 각 계통간에 복잡한 상호 관련성이 있다는 것. 2. 안전계통과 그의 해석에 고도의 신뢰성이 요구된다는 것. 그리고 3. 고가의 투자액이 소요된다는 것에 있다. 이러한 개념은 일단 채택 소화된 후에야 원자력발전소 후속기업무와 기타의 산업분야 및 산업경영에 까지 광범위하게 유익하도록 적용할 수가 있으며 이들의 적용은 생산성의 구체적인 증가를 유도함으로써 시간과 자본의 투자보상이 개선된다. 여기서는 주어진 시간이 제한되어 있으므로 이러한 개념중이 일부만을 골라서 개진한다.
