저자들은 간의 거대 종괴와 심방 중격 결손으로 수술을 받았던 환아에서 복부 CT와 간 조직 검사를 통해 확인된 Abernethy 기형 2형 1예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Extrahepatic portosystemic shunts, known as Abernethy malformations, were first reported by John Abernethy in 1793. They are classified into two types: Type I refers to a congenital absence of the portal vein and Type II refers to a shunt involving a side-to-side anastomosis with reduced portal blood flow into the liver parenchyma. This malformation is so rare that less than 100 cases have been reported in the medical literature. We report the case of a 13-month-old boy who had a congenital extrahepatic portocaval shunt with a hypoplastic portal vein. This case was complicated with an atrial septal defect and a large hyperplastic nodule in the liver. The patient was diagnosed with a Type II Abernethy malformation. We planned on surgical occlusion of the extrahepatic portocaval shunt. However, six months later, the patient had a sudden onset of a fever of unknown origin and developed hepatic encephalopathy. Although he underwent a liver transplantation, he died of acute hepatic failure.

Purpose: The purpose of this survey was to assess the satisfaction of patients suffering from musculoskeletal pain with physical therapy (PT) in Busan, Daegu, and Kyeongsang provinces using a Korean-language version of the patient satisfaction questionnaire with physical therapy service (PSPT). Methods: A total of 654 patients, having PT for their musculoskeletal pains, participated. Consenting subjects completed a 20-item PSPT on their $6^{th}$ or last treatment day. Simple descriptive statistics were used for respondent characteristics, and mean of satisfaction score in each item. Regression analysis was performed on each item of the questionnaire. Results: 654 subjects responded during or after their PT services. 297 (45.5%) of them were male and the most common site of pain was the spine. The mean of each item score (1-5) ranged from 2.14 for "my therapist did not listen to my concerns" to 4.12 for "my therapist treated me respectfully". Receptionist's attitude, registration process, service time of the hospital, and answer to the patient's questions greatly affected the general satisfaction of the respondents. Conclusion: The results showed high levels of satisfaction to the general process for obtaining treatment as well as the therapist's attitudes toward their patients. They may provide valuable patients' feedback regarding PT service for musculoskeletal pain. Therefore, it may be used by physical therapists to improve future patient experiences with a view to improving the patient's attendance and compliance with the PT service protocols for patients suffering from musculoskeletal pain.

Purpose: The purpose of this study was to investigate the characteristics of patients with Chronic Low Back Pain (CLBP) in disability, pain, and cognition, and to compare those characteristics to the ICF concept analyzing the association between World Health Organization Disability Assessment Schedule 2.0: 12 item-interviewer version (WHODAS 2.0) and those of scales i.e. Oswestry Disability Index (ODI), the Short-Form McGill Pain Questionnaire (SFMPQ), and the Fear avoidance & belief questionnaire (FABQ). Methods: A total of 91 patients with CLBP were invited to participate in the study. Physical therapists interviewed all participants using SFMPQ, FABQ, ODI, and WHODAS 2.0 for collection of information on pain, cognition, and functional level data. Subjects scored their disability, pain, and cognition related to LBP using WHODAS 2.0, ODI, SFMPQ, and FABQ. Data analysis was performed using the Spearman correlation coefficient. Results: A positive relationship was observed between WHODAS 2.0 and each scale indicating that lower back specific disability components could be related to the ICF concept in ODI (r=0.77). Pain intensity and pain oriented movement were found to be related to general functioning in patients with CLBP (r=0.52, r=0.55, respectively). Conclusion: It can be suggested that the specific disability scale for LBP, ODI can be related to the ICF concept, WHODAS 2.0, and it may be a useful measure for patients with CLBP.

Purpose: Recently, the performance of the X-ray tube was very much improved by the power generation of the technology. However, the overload of equipment is occurred by the increment of the equipment operating time according to the increment of the examination number of cases. The X-ray dose can change by heat occurrence of the X-ray tube due to this. Moreover, the change of the bone mineral density value is possible to occur. Therefore, We tries to whether the change of the bone mineral density value of each equipment according to the difference of the examination number of cases and operating time occur or not. Materials and Methods: The BMD value was measured by the Aluminum Spine Phantom and the European Spine Phantom in each equipment, in order to find out about the difference of the time general classification bone mineral density value by using the Dual energy X-ray absorptiometry. And after scanning each phantom by using X-ray dose meter (Unfors Mult-O-Meter), a dose was measured by the same condition. As to, an average and standard deviation were found and the change of each equipment much BMD value was compared and it evaluated. Results: $Mean{\pm}SD$ of each equipment by using the Aluminum Spine Phantom, A equipment was $1.174{\pm}0.002$, $1.171{\pm}0.005$, $1.173{\pm}0.005$, B equipment was $1.186{\pm}0.003$, $1.187{\pm}0.003$, $1.185{\pm}0.003$, C equipment was $1.180{\pm}0.003$, $1.182{\pm}0.004$, $1.183{\pm}0.002$, D equipment was $1.188{\pm}0.004$, $1.185{\pm}0.003$, $1.185{\pm}0.004$. By using the European Spine Phantom, A equipment was $1.143{\pm}0.006$, $1.153{\pm}0.009$, $1.161{\pm}0.003$, B equipment was $1.134{\pm}0.004$, $1.13{\pm}0.008$, $1.127{\pm}0.015$, C equipment was $1.143{\pm}0.006$, $1.134{\pm}0.01$, $1.133{\pm}0.006$, D equipment was $1.14{\pm}0.001$, $1.122{\pm}0.002$, $1.131{\pm}0.008$, altogether included in the normal range. Conclusion: There was no significant change of the BMD value of using a phantom by time zones. Therefore, if the quality control is made to use the extent management method of the equipment for beginning in the present application, the reliability of the BMD equipment will be able to be enhanced.

광 버스트 스위칭 망에서 최소 경로비용 기반의 동적 경로배정 기법

Optical burst switching networks usually employ one-way reservation by sending a burst control packet with a specific offset time, before transmitting each data burst Same. Due to such a Property, burst-contentions occur when multiple bursts contend for the same wavelength in the same output link simultaneously in a node, leading to burst losses, eventually degrading the quality of service. Therefore, in this paper, we propose a dynamic routing algorithm using minimum local state information in order to decrease burst-contentions. In this proposed scheme, if burst loss rate exceeds a threshold value at a certain node, a new alternative routing path is chosen according to burst priority and location of burst generation, which enables the contending bursts to detour around the congested link. Moreover, for reducing the effect of sending bursts on the primary path due to the alternative path, we also apply a minimum path-cost based routing on link-cost concept. Our simulation results show that proposed scheme improves the network performance in terms of burst loss probability and throughput by comparing with conventional one. 광 버스트 스위칭 방식은 제어 채널과 데이터 채널을 분리하여 버스트 제어 패킷을 제어 채널로 먼저 전송하고 Offset 시간 후에 도착할 데이터 버스트에 대한 데이터 채널을 예약하는 단방향 예약 특성을 가지고 있다. 그러나 이러한 특성 때문에 버스트 간에 데이터 채널을 예약하기 위한 경합이 발생하게 되며 경합에 실패한 버스트는 손실되어 심각한 QoS (Quality of Service) 저하를 초래한다. 따라서 본 논문에서는 버스트 손실을 최소화하기 위해 노드에서 발생되는 버스트 손실이 임계값을 초과할 경우 버스트 우선순위와 버스트가 생성된 근원지 정보에 따라 유동적으로 경로를 재설정하는 동적 경로 설정 기법을 제안하였다. 이와 같이 제안된 기법은 기존 경로로 전송되고 있는 버스트 흐름에 영향을 최소화하기 위하여 링크 비용을 고려한 최소 경로 비용을 기반으로 하고 있다. 또한, 제안된 기법의 성능 평가를 위하여 버스트 손실률, 버스트 처리율 및 평균 흡수 관점에서 기존의 기법과 비교 평가하였다.

자체 제작된 팬텀을 적용한 Breast Specific Gamma Imaging 검사 프로토콜에 대한 고찰

이해정,이주영,임근교,박훈희,Lee, Hae-Jung,Lee, Juyoung,Lim, Kuen-Kyo,Park, Hoon-Hee 대한핵의학기술학회 2014 핵의학 기술 Vol.18 No.2

유방암 환자가 매년 증가함에 따라 BSGI 검사에 대한 의존도가 높아지고 검사 건수가 증가하고 있는 추세이다. 하지만 국내에서 BSGI 검사는 각 기관의 상황 및 업체권고에 따라 검사 프로토콜을 적용하고 있으며 관련 연구가 미비한 실정이다. 그러므로 본 연구에서는 영상의 질을 평가할 수 있는 팬텀을 자체적으로 제작하여 검사 프로토콜에 대해 고찰하고자 하였다. Dilon 6800 BSGI 장비를 이용하여 팬텀 내 구의 크기는 5단계로 구분하여 제작하여 실험하였다. 방사성동위원소는 $^{99m}TcO_4$를 사용하여 배후방사능과 관심영역의 비율을 2 : 4 : 8로 구분하였으며 5, 7, 10분 영상을 획득하였다. 획득된 영상은 각 구의 크기에 따라 관심영역을 설정하고 정량적, 정성적 분석을 시행하였다. 획득된 데이터는 SPSS ver.18.0을 통해 통계 분석하였다. 정량적, 정성적 분석 결과, 방사성동위원소의 주입량에 따른 각 구의 계수율은 주입량이 많을수록 계수율이 증가하였고, 구의 크기가 클수록 계수율이 증가하는 성향을 나타냈다(p<0.005). 영상획득시간에 따른 각 구의 계수율은 획득시간이 길수록 계수율이 증가하였고, 구의 크기가 클수록 증가하는 성향을 나타냈다(p<0.005). 방사성동위원소의 주입량에 따른 각 구의 대조도 잡음비는 주입량이 많을수록 증가하는 성향을 나타냈고, 8배 비율의 획득영상에서 대조도 잡음비가 가장 높았다. 또한 영상획득시간에 따른 각 구의 대조도 잡음비는 획득시간이 길수록 증가하는 성향을 나타냈고, 7분 획득영상에서 대조도 잡음비가 가장 높았다(p<0.005). 자체적으로 제작한 팬텀을 통한 정량적, 정성적 평가에서 통계적으로 유의한 차이가 있었으며, 팬텀의 유용성을 확인할 수 있었다. 또한 본 연구를 통해 장비 특성과 환경을 고려하여 BSGI 검사 프로토콜을 확인하고 활용한다면 보다 임상적 가치가 높을 것으로 사료된다. Purpose As breast cancer patients continue to increase every year, cases of BSGI are on the rise with a heavier reliance on it. However, BSGI protocol in hospitals was not studied enough despite it was covered by hospital's condition and recommendation of manufacturers. The objective of the study was an examination of methods to be applicable to BSGI protocols, putting the self-development phantom to use in quality assessment of the images. Materials and Methods Dilon 6800 (Dilon Technologies Inc, Newport News, USA) was used in the study and five different sizes of sphere were distinctively produced in the phantom. The study used $^{99m}TcO_4$. The cases were classified in to three categories that background radioactivity to region of interest as ratio of 2: 4: 8, They were acquired images for 5, 7, 10mins. The acquired image was set region of interest according to the size of sphere, and We analyzed quantitative and qualitative analysis. The acquired data statistically analyzed with SPSS ver.18.0. Results As the result of quantitative and qualitative analysis, count rate of each sphere in accordance with difference of injection dose showed that higher count rate as injection dose and sphere size increased (P<0.005). Count rate of each sphere in accordance with difference of acquisition time showed that higher count rate as acquisition time and sphere size increased (P<0.005). Contrast noise ratio of each sphere in accordance with difference of injection dose showed that higher contrast noise ratio as injection dose increased. Particularly, Contrast noise ratio of eight times ratio images was the highest among. Contrast noise ratio of each sphere in accordance with difference of acquisition time showed that higher contrast noise ratio as acquisition time increased. And, Contrast noise ratio of seven minute image was the highest among (P<0.005). Conclusion There was significant change of Contrast noise ratio through quantitative and qualitative analysis. Moreover, We found usefulness of phantom. If Institutions identified image through the phantom study and they made BSGI protocol, We expected to help the improvement of diagnostic value of the images.

이해정,송주민,Lee, Haejung,Song, Jumin 대한물리치료학회 2014 대한물리치료학회지 Vol.26 No.5

Purpose: The purpose of this study was to translate and culturally adapt the International Classification of Functioning, Disability and Health (ICF) into the Korean language. Methods: The process of translation and adaptation of the ICF used here followed the translation guidelines of WHO. Implementation of this procedure comprised of four steps; forward translation, expert panel back-translation, pre-testing and cognitive interviewing, and final adaptation. The translators included health professionals with knowledge of ICF and non-health professionals blinded to the ICF. Clinical academics with significant experience in the use of disability survey, medical doctors, special educators, related policy makers, clinicians, architecture professionals, and international experts in ICF were invited to integrate all versions of the ICF for testing; 151 clinicians volunteered from 19 medical institutes across the country. Four different core-sets and a questionnaire were used for testing its practical usability and adaptation. Results: All translations were reviewed and a consensus was reached on any discrepancy from the earlier versions. Over 90% of the newly translated version of K-ICF was found to be different from the 2004 K-ICF version in the ICF language. Understanding of K-ICF language was responded difficult and very difficult by 50% of participants, whereas its practical use was responded 'useful' by more than 50% of subjects. Conclusion: It can be suggested that the new version of K-ICF should be widely used for final adaptation in the field of areas. Future studies will be required for implementation of K-ICF.

독일어 제 2분사(Partizip II)의 부가전적인 형용사화에 따른 문법상의 제약

이해정,Lee Hae-Jong 한국독어학회 2003 독어학 Vol.8 No.-

In diesem Aufsatz versuche ich, die $Grammatikalit\"{a}t$ der attributiven Adjektive zu beurteilen, die aus ihren Basisverben abgeleitet sind. In den bisherigen Untersuchungen der deutschen Syntax sind die $Ausdr\"{u}cke$ wie das verbrannte Papier, die $aufgebl\"{u}hte$ Rose, die verklungene Glocke als grammatisch angenommen worden. All diejenigen Adjektive sind aus den Ereignissverben abgeleitet. Fraglich ist nun, ab man die Attribuierung der Adjektive aus den Fortbewegungs­verben kommen, gehen, laufen auch fur akzeptabel halten soli. Einige Beispiele wie der in Heidelberg angekommene Zug, der aus dem $B\"{u}ro$ gelaufene Mann zeigen, dass die Ableitung der attribuierten djektive auch fur Fortbewegungsverben $m\{o}glich$ sei. Auf der anderen Seite kann man diejenigen Beispiele schwer akzeptieren, wie der zum Bahnhof gegangene Mann, der $\"{u}ber$ den Fluss geschwommene Junge, die aus kommen, gehen, laufen usw. abgeleitet sind. Die entscheidenden Kriterien der $Grammatikalit\"{a}t$ liegen darin, dass die Ableitung der attribuierten Adjektive $haupts\"{a}chlich$ folgende Bedingungen $erf\"{u}llen$ soli: 1. Das an dem Ereignis beteiligte Argument muss eine Theta-Rolle [THEME] haben. 2. Das Argument soli irgendwie qualitativ oder quantitativ $ver\"{a}ndert$ werden. 3. Das Ereignis muss eine $Ver\"{a}nderung$ zeigen, die Anfangszustand, Endzustand und auch eine $\"{U}bergangszeit$ dazwischen beinhaltet. Mit diesen Kriterien habe ich die $Grammatikalit\"{a}t$ der wichtigen Beispiele der Attribuierung entscheiden $k\"{o}nnen$, die in der deutschen Linguistik theoretisch viel diskutiert worden sind.
