목 적 : 종속조사면 병합 치료방법(FIF : Field In Field)을 이용한 유방절선조사 시 반대편 유방의 표면선량을 평가하고자 한다. 대상 및 방법 : FIF치료방법 이용 시 반대편 유방에 흡수되는 표면선량을 평가하고자 동일한 기하학적 조건과 처방선량을 기반으로 열린조사면(Open), 금속쐐기(MW : Metal Wedge), 동적쐐기(EDW : Enhanced Dynamic Wedge)를 이용한 조사방법과 비교하였다. 3차원 치료계획장치를 이용하여 선량분포 최적화를 수행하였으며 계산 결과의 정확도를 검증하기 위해 인체 팬톰과 모스펫 측정기를 사용하여 측정을 수행하였다. 동측 유방 입사면 가장자리로부터 반대편 유방 쪽으로 2, 4, 6, 8, 10 cm 지점을 선정하여 각각 표면(0 cm :가피)과 0.5 cm(진피) 깊이에서 선량을 측정하였으며, 0.5 cm 깊이 선량측정을 위해서 0.5 cm 볼루스를 사용하였다. 선량분포의 계산은 불균질 물질을 보정(modified Batho method)하여 0.25 cm 격자 해상도로 수행하였다. 결 과 : 치료계획장치에서 각 지점의 평균표면선량은 금속쐐기의 경우 표면 및 0.5 cm 깊이에서 19.6~36.9%, 33.2~138.2% 증가했고, 동적쐐기는 1.0~7.9%, 1.6~37.4%까지 증가하였다. FIF는 -18.4~0.7%,-8.1~4.7%까지 선량이 변화하였다. MOSFET을 이용하여 측정한 경우는 금속쐐기는 표면 및 0.5 cm 깊이의 경우 11.1~71%, 22.9~161.2% 증가했고, 동적쐐기는 4.1~15.5%, 8.2~37.9% 선량이 증가했다. FIF는 표면에서-15.7~-4.9%로 선량이 오히려 감소했으며, 0.5 cm 깊이에서의 선량도 -10.5~3.6%로 나타났다. 치료계획장치의 계산값과 실측값을 비교한 결과, 유사한 경향을 보였으나 치료계획장치의 경우 피부선량이 실제측정값보다 다소 과소평가되고 있음을 알 수 있었다. 결 론 : 본 실험을 통해 FIF치료방법의 경우 기존 치료방법(MW, EDW)에 비해 치료표적에 최적화 된 선량 분포를 만들어 내면서도 반대편 유방의 피부에 불필요한 산란선량을 최소화하는 치료방법임을 알 수 있었다. The aim of this study is to evaluate contra-lateral breast (CLB) surface dose in Field-in-Field (FIF) technique for breast conserving surgery patients. For evaluation of surface dose in FIF technique, we have compared with other techniques, which were open fields (Open), metal wedge (MW), and enhanced dynamic wedge (EDW) techniques under same geometrical condition and prescribed dose. The three dimensional treatment planning system was used for dose optimization. For the verification of dose calculation, measurements using MOSFET detectors with Anderson Rando phantom were performed. The measured points for four different techniques were at the depth of 0 cm (epidermis) and 0.5 cm bolus (dermis), and spacing toward 2 cm, 4 cm, 6 cm, 8 cm, 10 cm apart from the edge of tangential medial beam. The dose calculations were done in 0.25 cm grid resolution by modified Batho method for inhomogeneity correction. In the planning results, the surface doses were differentiated in the range of 19.6~36.9%, 33.2~138.2% for MW, 1.0~7.9%, 1.6~37.4% for EDW, and for FIF at the depth of epidermis and dermis as compared to Open respectively. In the measurements, the surface doses were differentiated in the range of 11.1~71%, 22.9~161% for MW, 4.1~15.5%, 8.2~37.9% for EDW, and 4.9% for FIF at the depth of epidermis and dermis as compared to Open respectively. The surface doses were considered as underestimating in the planning calculation as compared to the measurement with MOSFET detectors. Was concluded as the lowest one among the techniques, even if it was compared with Open method. Our conclusion could be stated that the FIF technique could make the optimum dose distribution in Breast target, while effectively reduce the probability of secondary carcinogenesis due to undesirable scattered radiation to contra-lateral breast.

According to the Maritime Safety Act, there are all 34 routes including 5 traffic safety zones, 3 traffic separation schemes, 26 routes designated by regional maritime affairs departments in the Republic of Korea. In the SOLAS convention, the route information should be is effectively used for the safe navigation. However, the route information is complicatedly composed of the location of the route, the navigation rule by each route, the restriction of the navigation, and the anchorages. Moreover, the present method of providing information using the navigational chart and other publications is not effective for users to grasp the navigational information. Therefore, it was conducted to study the design of the S-100 based routing information data model developed by the International Hydrographic Organization to find ways to more effectively provide route information. To do this, the analysis of route requirement, selection of items, encoding test and users’ review were carried out. Through expert user review, it was evaluated that the study on the design of the route information data model can be utilized as a good basic data for the route information integration service. Future research on the development of route information data models is expected to provide integrated route information services.

본 연구의 목적은 유방암 환자의 절선조사 시 종속조사면 병합(FIF) 치료방법을 2차원 이온전리함을 이용하여 불균등한 선량분포를 확인하고자하였다. 실험을 위해 2차원 이온전리함 배열(MatriXX, Wellhofer Dosimetrie, Germany)와 치료계획장치(Eclipse, ver 6.5, Varian, Palo Alto, USA)가 사용되었다. 불균등한 선량분포 확인을 위해 FIF 방법으로 치료계획 한 20명의 환자를 선택하여 각각 90 cGy를 처방하여 하이브리드 계획을 수행하였으며, 측정값과 비교를 위해 동일한 기하학적 조건에서 MatriXX를 이용해 측정하였다. 정량적인 분석을 위해 상용화된 분석 소프트웨어(OmniPro IMRT, ver, 1.4, Wellhofer, Dosimetrie, Germany)를 이용하여 분석하였다. 실험 결과로 기준점에 선량처방 시 계산값과 측정값이 평균 1.6% 차이를 보였고, 선형프로파일 (Line-Profile)을 통해 분석한 결과 종단면에서는 1.3-5.5%(평균 : 2.4%), 횡단면에서는 0.9-3.9%(평균 : 2.5%)로 변동을 보였다. 감마인덱스 히스토그람(기준 : 3 mm, 3%)로 분석한 결과 90.23-99.69%(평균 :95.11%, 표준편차 : 2.81) 범위를 나타냈다(유효범위 ; γ-index ≥ 1). 본 실험에서는 MatriXX 이용하여 측정한 결과 치료계획 선량과 측정값이 오차범위 이내로 일치하였으며, 향후 다양한 종양치료에 있어 FIF방법의 활용도를 높이는 연구가 필요하다고 생각한다. The study is to verify non-uniform dose distribution in Field-In-Field (FIF) technique using two-di-mensional ionization chamber (MatriXX, Wellhofer Dosimetrie, Germany) for breast tangential irradiation. The MatriXX and an inverse planning system (Eclipse, ver 6.5, Varian, Palo Alto, USA) were used. Hybrid plans were made from the original twenty patients plans. To verify the non-uniform dose distribution in FIF technique, each portal prescribed doses (90 cGy) was delivered to the MatriXX. The measured doses on the MatriXX were compared to the planned doses. The quantitative analyses were done with a com-mercial analyzing tool (OmniPro IMRT, ver. 1.4, Wellhofer Dosimetrie, Germany). The delivered doses at the normalization points were different to average 1.6% between the calculated and the measured. In analysis of line profiles, there were some differences of 1.3-5.5% (Avg: 2.4%), 0.9-3.9% (Avg: 2.5%) in longitudinal and transverse planes respectively. For the gamma index (criteria: 3 mm, 3%) analyses, there were shown that 90.23-99.69% (avg: 95.11%, std: 2.81) for acceptable range (γ -index ≥ 1) through the twenty patients cases. In conclusion, through our study, we have confirmed the availability of the FIF technique by comparing the calculated with the measured using MatriXX. In the future, various clinical applications of the FIF techniques would be good trials for better treatment results.

본 연구는 국내의 부족한 골재자원확보, 폐기물 재활용 및 콘크리트의 품질향상을 목적으로 시도되었다. 즉, 잔골재의 혼합은 굵은 입자를 많이 포함하여 표준입도범위를 벗어나는 석산B(CSb) 및 건설현장의 터파기한 발파석을 분쇄한 발파석(BS)과 미세한 입자를 많이 포함하여 표준입도범위를 벗어나는 해사(SS)를 혼합하는 것으로 한다. 또한, CSb+SS, BS+SS를 혼합골재로 제조할 경우, 전반적으로는 표준입도범위에 포함될지라도 0.15mm이상의 미립자가 부족하므로서 모르타르 및 콘크리트 품질에 결함으로 나타날 수 있다. 따라서 여기에 겨울철 초기강도에 기여하지 못하므로서 버려지는 화력발전소의 미정제 석탄회(Ra)를 0~10% 범위에서 치환하는 것을 검토하였다. 연구결과, CSb 혹은 BS와 SS를 6:4의 비율로 혼합하여 혼합골재로 제조하고, 여기에 Ra를 5% 치환할 경우 골재의 입도측면 및 시멘트 모르타르의 품질 측면에서 가장 양호한 결과가 얻어짐을 확인 할 수 있었다. The aim of the research is improving the quality of concrete by using the alternative aggregate resources and recycling wastes. To make a combined aggregate fitted in standard particle size distribution curve, crushed sand from blasted rock debris was used as a base aggregate. Additionally, to increase the portion of fine particles, sea sand was mixed. Although these aggregate combination fit the standard particle size distribution curve, in this research, raw coal ash was replaced as a microfine. According to the experiment, by replacing 5% raw coal ash, the most favorable results were achieved in aggregate gradation and cement mortar quality.

Purpose: Few researches have been peformed on the dose distribution of the moving organ for radiotherapy so far. In order to simulate the organ motion caused by respiratory function, multipurpose phantom and moving device was used and dosimetric measurements for dose distribution of the moving organs were conducted in this study. The purpose of our study was to evaluate how dose distributions are changed due to respiratory motion. Materials and Methods: A multipurpose phantom and a moving device were developed for the measurement of the dose distribution of the moving organ due to respiratory function. Acryl chosen design of the phantom was considered the most obvious choice for phantom material. For construction of the phantom, we used acryl and cork with density of $1.14g/cm^3,\;0.32g/cm^3$ respectively. Acryl and cork slab in the phantom were used to simulate the normal organ and lung respectively. The moving phantom system was composed of moving device, moving control system, and acryl and cork phantom. Gafchromic film and EDR2 film were used to measure dose ditrbutions. The moving device system may be driven by two directional step motors and able to perform 2 dimensional movements (x, z axis), but only 1 dimensional movement(z axis) was used for this study. Results: Larger penumbra was shown in the cork phantom than in the acryl phantom. The dose profile and isodose curve of Gafchromic EBT film were not uniform since the film has small optical density responding to the dose. As the organ motion was increased, the blurrings in penumbra, flatness, and symmetry were increased. Most of measurements of dose distrbutions, Gafchromic EBT film has poor flatness and symmetry than EDR2 film, but both penumbra distributions were more or less comparable. Conclusion: The Gafchromic EBT film is more useful as it does not need development and more radiation dose could be exposed than EDR2 film without losing film characteristics. But as response of the optical density of Gafchromic EBT film to dose is low, beam profiles have more fluctuation at Gafchromic EBT. If the multipurpose phantom and moving device are used for treatment Q.A, and its corrections are made, treatment quality should be improved for the moving organs.

The countries are trying to expand the sea limit such as the territorial sea, fishing zone or the exclusive economic zone as far as the Law of the Sea permit to do for the benefit of their national interest. Especially, they are eager to claim the base point where it locates far from the coastline even if it is uninhabited island or reef under the sea. The baseline has been claimed to maximize the territorial sea. Another way to expand the sea limit is to lower the vertical datum to change the land limit. China claimed Dongdo which is located about 79 miles far from the coast as the base point. Japan also claimed many uninhabited island or the reef which is located very far from the coast such as Okino Dorishima. As Korea is the party who negotiate the maritime limit with Japan and China, we should be keen and sensitive on the issues claimed by neighboring countries in terms of base point and the baseline. This paper is to review the characteristics of the base points or baselines of neighboring countries and to suggest the views how to maintain and to relocate our base points. As western coast of Korean peninsula is one of the largest tide fluctuation zone in the world, with long tidal record to prove the vertical datum adjustment, Korea can find the way to lower the vertical datum especially in Yellow Sea. So, major and critical tidal station has to be set up along the western coast to verify tide fluctuation record which can be met with international standard. 각국은 유엔 해양법 협약의 규정 하에서 자국의 영해, 어업수역, 배타적 경제수역을 확장할 수 있는 방법을 모색하고 있다. 이를 위한 노력은 두 가지 측면에서 나타나는데 그 하나는 기점을 최대한 해안선에서 멀리 떨어진 곳으로 정하는 것과 다른 하나는 수직기준면의 조정이 자국의 수역확장에 도움이 되는가에 대한 분석과 자료수집이다. 우리나라는 유엔 해양법 협약의 발효에 따라 1996년부터 꾸준히 영해를 마주보고 있는 일본 중국과 해양경계 획정 회담을 해 오고 있으나 한 일, 한 중 간의 해양경계협정에 많은 장애가 있으며 그 과정에서 우리나라의 해역확장을 위해 기점과 수직기준면 설정이 매우 중요하며, 이에 대한 철저한 대비가 필요하다. 본 논문에서는 인접국의 기점과 기선관리 실태를 파악하고 문제점을 분석하고 우리나라의 기점과 영해확장을 위한 방안을 모색하였다. 직선기점의 설정과 관련하여 국제해양법 협약에 위배되지 않으면서 영해확장을 도모할 수 있는 기점에 대한 검토와 국제수로기구(IHO)에서 권장하는 수직기준면에 대한 검토는 우리나라의 영해확장을 위해 반드시 필요하다. 이는 경계획정 회담에서 우리나라의 영해 획정의 기술적인 근거가 될 수 있다.
