저자들은 임상적 소견과 검사실 소견에서 전염성 단핵구증으로 확진한 환아에게서 폐렴과 흉막 삼출액이 동반된 드문 1례를 경험하였다. 이에 문헌고찰과 함께 보고하는 바이다. Infectious mononucleosis(IM) is a clinical syndrome characterized by fever, exudative tonsillitis, gerneralized lymphadenopathy(90% of cases), splenomegaly(50% of cases), and hepatomegaly(10% of cases). It is mainly caused by Epstein-Barr virus(EBV) and usually recovered completely in the majority of cases. The complications of IM are splenic rupture, pancreatitis, hematologic problems such as hemolytic anemia, aplastic anemia, and thrombocytopenia, neurologic problems such as meningitis, encephalitis, and Guillian-Barr$\acute{e}$ syndrome, myocarditis, parotitis, orchitis, and interstitial pneumonitis, etc. Pulmonary involvement with EBV infection is rare condition reported frequency of 3% to 5%, in addition pleural effusion has been very rarely reported, especially in the pediatric population. We herein report a case of IM with pleural effusion in 3 years old boy with fever, cervical lymphnodes enlargement, and hepato-splenomegaly. And the pleural effusion is spontaneously resolved for a hospitalization period. A brief review of literature is included.

본 논문에서는 변이계수에 대한 영향함수를 유도한다. 경험적 영향함수와 표본영향함수를 이용하여 유도된 영향함수의 타당성을 입증하고 이를 위하여 정규분포 $N(20,1^2)$와 $N(20,5^2)$에서 각각 확률표본을 추출하여 시뮬레이션을 수행한다. 시뮬레이션 결과로부터, 유도된 변이계수에 대한 영향함수가 한 개의 관찰치가 제거되었을 때 변이계수의 변화량을 매우 정확히 추정하는 것을 확인하였다. We derive the influence function on the coefficient of variation. Empirical influence function and Sample influence function are used to verify the validity of the derived influence function. To show the validity of the influence function, we carry out simulations with random samples from normal distribution $N(20,1^2)$ and $N(20,5^2)$, respectively. The simulation result proves that the derived influence function is very accurate in estimating changes in the coefficient of variation when an observation is deleted.

Carcinous pain is severe and continuous so difficult to alleviate. Western drugs give rise to reaction such as anorexia, constipation, vomiting, general weakness and dyspnea, And they cause tolerence. External treatment is a way to put a patch or rub a liquid on the skin. The patch and liquid are made from herb medicine. In china, they have a good effect of alleviating carcinous pain to make use of external treatment. Usually they use the medicine with effect of reprecussion (消腫), removing obstruction(散結), activating blood flow and removing blood stasis (活血化瘀) such like Borneloum(?片). Bufonis Venenum (蟾?), Aconiti ciliane Tubber(草烏), Arisaematis Rhizoma(南星), Asari herba cum Radice (細辛) etc. We can get the alleviating effect more quickly and prevent reaction through external treatment.

전신조사방사선치료 시 Isodose Structure를 이용한 Field-in-Field Technique의 유용성 평가

이윤희,반태준,이우석,강태영,백금문,Lee, Yoon Hee,Ban, Tae Joon,Lee, Woo Seok,Kang, Tae Young,Back, Geum Mun 대한방사선치료학회 2013 대한방사선치료학회지 Vol.25 No.1

목 적: 본원에서는 전신조사방사선치료 시 양 팔을 몸에 붙이고 누워있는 환자에게 좌우 양방향으로 방사선을 조사한다. 누운 자세는 기준점 두께에 대하여 신체 다른 부위와 두께 차이가 크기 때문에 보상체의 제작이 필요하고, 기준 깊이(Umbilicus) 처방선량에 대하여, 양팔(Arms)로 가려지지 않은 흉부와 복부 전면(Anterior)은 최대 20%까지의 선량차이가 나는 고 선량 영역이 된다. 이에 본 연구에서는 전신조사방사선치료 시 고 선량 영역과의 선량 차이를 줄일 수 있는 Isodose Structure를 이용한 Field-in-Field (FIF) Technique의 유용성을 평가 하고자 한다. 대상 및 방법: 인체모형등가팬텀(Rando Phantom, Alderson Resarch Laboratories Inc. Stamford. CT, USA, With Arm)으로 전산화단층촬영모의치료기의 영상을 획득하여 FIF와 납(Pb) 보상체를 이용한 전산화치료계획(Eclipse, version 10.0, Varian, USA)을 수립하였다. 두 치료계획의 흉부와 복부 부위의 선량분포를 비교하고, 수립된 치료계획을 이용하여 인체모형등가팬텀에 선량을 조사한 후, 열형광선량계(thermoluminescence dosimeter, TLD)와 필름(Film)을 이용하여 측정하였다. 결 과: 두 치료계획을 비교해 본 결과 기준깊이 처방선량에 대하여 팔로 가려지지 않은 흉부와 복부 전면의 선량차이는 FIF에서는 106~107%, 납 보상체를 이용한 치료계획에서는 114~124%였다. 열형광선량계를 분석한 결과로 FIF에서는 104~107%, 납 보상체를 이용한 치료계획에서는 110~117%의 기준깊이 처방선량과의 선량차이가 나왔다. 결 론: 본 실험에서 인체모형등가팬텀에 양 팔을 제작하여 치료 계획 및 선량을 조사해 보았다. 양 팔의 투과 유무에 따라 약 7~17%의 선량차이가 발생 하였다. 4단계의 FIF 기법으로 3차원 치료계획을 수립하여 전신에 약 95~107%의 균등한 선량 분포를 확인하였고 ${\pm}10%$ 이내의 선량 균일성을 유지 할 수 있을 것으로 분석 되었다. FIF 기법을 이용한 3차원 치료 계획은 환자 전신에 조사되는 선량을 미리 분석 할 수 있는 치료 계획으로 기존 치료 방법보다 균등한 선량의 전달이 가능할 것으로 사료된다. 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.

In the modernization process of the city, urbanization raised a variety of social issues. Urbanization brought noticeable changes in dwelling patterns, such as drastic changes in the housing lifestyle, that revolved around the metropolitan areas of Seoul and Busan etc. before and after the expansion of economic growth. Especially in 1985, when 23.8% of the country's population was concentrated in Seoul, the imbalance of housing supply and demand caused a vast range of housing shortage. The shortage, that resulted from public sector mishandling of natural housing demand, lead to the occurrence of private sector rental housing. The occurrence of this abnormal rental housing supply, became a major cause of Korea's typical lease system called 'Co-dwelling', where the leaseholder and tenant physically lives in the same residence. The leaseholder and tenant's 'Co-dwelling' started from partial renting of traditional Korean-style housing and transformed with the transition of dwelling form and time. However, after 1985, legalization of multi-family housing, Korean rental housing started to be planned in the beginning of it's housing construction and to be produced as an independent space with separate circulation. Also in terms of facility, it changed from partial renting of a space within the residence to an assembly of small individual spaces. However, the background of this deep-rooted 'Co-dwelling' lease system, in different forms and periods of residence, is still based on the lack of public sector rental housing supply and private sector supply of rental space to utilize extra space, 'Jeonsei' payment.
