저자들은 복부 외상 후 크기가 증가하는 종괴와 동통을 주소로 내원한 13세 여아에서 췌장 원위부 절제술을 시행하여 조직학적으로 췌장 고형유두상피 종양을 진단하였기에 문헌고찰과 함께 보고하는 바이다. Solid and papillary epithelial neoplasm (SPEN) of the pancreas is an uncommon tumor and is found predominantly in young females. The most common clinical presentation is an abdominal mass. The tumor has a low grade malignant potential and complete removal is the treatment of choice. We report a case of SPEN in a 13-year-old girl who presented with abdominal pain and increasing size of an abdominal mass after abdominal trauma. CT and sonographic findings showed a well-demarcated mass in the pancreas tail with solid and cystic portion. She got a distal pancreatectomy and pathologic finding was SPEN of pancreas.

정상 MRI 소견을 보이는 외상성 뇌손상 환자에서 국소뇌혈류량의 이상

김남희,정영기,Kim, Nam-Hee,Chung, Young-Ki 대한생물정신의학회 2002 생물정신의학 Vol.9 No.2

Background & Purpose:Neuropsychological disorders after traumatic brain injury(TBI) are poorly correlated with structural lesions detected by structural neuroimaging techniques such as computed tomography(CT) scan or magnetic resonance imaging(MRI). It is well known that patients with TBI have cognitive and behavioral disorders even in the absence of structural lesions of the brain. This study investigated whether there are abnormalities of regional cerebral blood flow(rCBF) in TBI patients without structural abnormality on MRI, using technetium 99m ethyl cysteinate dimer(Tc-99m-ECD) single photon emission computed tomography(SPECT) scans. Materials and Methods:Twenty-eight TBI patients without structural abnormality on MRI(mild, n=13/moderate, n=9/severe, n=6) and fifteen normal controls were scanned by SPECT. A voxel-based analysis using statistical parametric mapping(SPM) was performed to compare the patients with the normal controls. Results:rCBF was reduced in the right uncus and the right lateral orbitofrontal gyrus in the TBI patients. However, no increase of rCBF was noted in the patients in comparison to the normal controls. Conclusions:These results suggest that the TBI patients, even in the absence of structural lesion of the brain, may have dysfunction of the brain, particularly of the orbitofrontal and anterior pole of the temporal cortex. They also suggest that SPECT can be a useful method to identify brain dysfunctions in combination with structural brain imaging and neuropsychological tests.

This study is a case study of system improvement measures for urban regeneration of the historical and cultural environment. The example areas are Hwangnam and Inwang Hanok districts in Gyeongju City, which operate various systems to solve the urban decline problem caused by the historical and cultural environment regulations. The subjects of this study are resident support programs and district unit planning systems under the advanced promotion system established in the case area. As research methods, literature studies, field surveys, and in-depth interviews were conducted. Through this, the background and purpose of introduction of each system, major plan contents, and problems of the system application process were analyzed. This study drew the following implications through case studies. First, in order to more effectively promote the urban regeneration of the historical and cultural environment, it is necessary to improve the related systems in an integrated and systematic manner. Second, in order to resolve the policy distrust of local residents in the historical, cultural and environmental management system, a wider variety of planned alternatives to narrow the difference in interests between the public and private sectors should be presented.

김남희,고현무,홍성걸,Kim, Nam-Hee,Koh, Hyun-Moo,Hong, Sung-Gul 한국전산구조공학회 2010 전산구조공학 Vol.23 No.4

개념적 설계단계에서 교량형태를 자유롭게 생성하는 것이 매우 중요하다. 그러나 공학적 설계자의 입장에서는 다양한 형태를 상상하기 보다는 힘의 전달방식에 따른 구조시스템의 종류를 우선적으로 생각하게 된다. 이 연구에서는 교량형태를 기하학적 측면에서 새롭게 살펴봄으로써 기존의 공학적 접근법에서 막혔던 상상력의 한계를 확장시키고자 한다. 우선적으로 기존교량의 형태를 기하학적으로 분석하고, 기하학적 특징이 뚜렷한 교량형태에 대해서는 이 연구에서 제시하는 기하학적 접근법을 이용해서 생성해본다. 이 연구의 초점은 새로운 구조물 형태생성의 기하학적 원리를 개발하는 것이 아니라, 기존의 정립된 기하학적 원리를 이용하여 다양한 설계대안을 생성하는 접근법을 제시하고자 한다. In conceptual design stage it is important to develop structural forms freely. However, structural engineers are prompt to consider types of structural systems following load paths rather than to imagine various forms. This study attempts to expand the limit of imagination that was blocked within engineering approach newly from geometric perspective view. First of all, existing bridge structures are reviewed in terms of geometric vocabulary. Some bridge forms showing apparent geometric features are regenerated through the geometric approach proposed in this study. This study is not to develop geometric principle to build new structural forms, but to propose the geometric approach to generate design alternatives using the well established geometry concepts.

This study was conducted to investigate the relationship among dietary behavior, meal balance, and clinical symptoms related nutritional status and Attention Deficit Hyperactivity Disorder(ADHD) in preschool children. The survey was conducted using questionnaires and the subjects were 3~6 years old preschool children in Samcheok. Subjects were divided into an ADHD dispositions group(n=88) and a normal group(n=129) based on assessments conducted by the children's mother using the Abbreviated Conners's Parent Rating Scale. There was no significant difference in meal frequency, meal speed, meal regularity or meal balance between children with ADHD dispositions and the normal groups. The ADHD disposition group had a higher proportion of children with picky eating(p<0.05), too much snacking(p<0.05) and over eating (p=0.05) habits than the normal group. In addition, the ADHD dispositions group had a higher frequency of clinical symptoms such as 'breathlessness when going up stairs', 'sleeplessness', 'anxiety' and 'tiredness'. Overall, there was a significant relationship between ADHD disposition and dietary problems and clinical symptoms related to poor nutritional status in preschool children. Therefore, to prevent and treat ADHD in preschool children, proper dietary management such as correcting of picky eating, over snacking and overeating is needed.

라인 세그먼트를 이용한 향상된 Star Topology Aggregation

김남희,Kim, Nam-Hee 한국정보처리학회 2004 정보처리학회논문지 C : 정보통신,정보보안 Vol.11 No.5

In this paper, we aggregate multi-links information between boundary nodes using the line segment scheme that aggregates topology in-formation within PG referring bandwidth and delay parameter. The proposed scheme can search multi-links efficiently using the depth priority method based on hop count instead of searching all links. To do this, we propose a modified line segment algorithm using two line segment method that represents two points which consist of delay-bandwidth pair to reduce topology information and provide a flexibility to the multi pie-links aggregation. And we apply it to current star topology aggregation. To evaluate performance of the proposed scheme, we compare/analyze the current method with the proposed scheme with respect to call success rate, access time and crankback rate. Through the simulation result analysis, the proposed star topology aggregation scheme presents the better performance than existing scheme. 본 논문에서는 대역폭과 지연 파라미터를 참조하여 PG내의 토폴로지 정보를 하는 기법으로 라인 세그먼트를 이용하여 경계노드 사이의 다중 경로 정보를 하였다. 제안된 star 토폴로지 기법에서는 모든 경로를 찾는 대신 홉 카운트 기반의 깊이 우선 방식을 사용하여 효율적으로 다중 경로를 탐색할 수 있도록 하였다. 이를 위해 토폴로지 정보를 줄이고 다중링크 에 유연성을 부여하기 위하여 대역폭과 지연의 한 쌍으로 구성된 두 개의 라인 세그먼트를 이용하는 수정된 라인 세그먼트 기법을 제안하였다. 그리고, 이를 기존의 star 토폴로지에 적용한 효율적인 토폴로지 기법을 제안하였다. 제안된 기법의 성능을 평가하기 위해 기존의 star 기법과 호 성공율, 접근시간 및 크랭크 백율에 대하여 컴퓨터 시뮬레이션을 통해 비교 분석하였다. 시뮬레이션 분석결과 제안된 star TA 기법이 기존의 기법보다 성능이 향상됨을 알 수 있었다.

압축력에 강한 석조 홍예아치교의 경우 재료적 음력한계보다는 구조적 형상의 불안정성에 의해서 구조물이 붕괴된다. 이러한 특성을 고려하면, 석조 홍예아치교의 구조적 안정성 평가에는 구조물의 붕괴기구 형상에 초점을 둔 한계상태 해석이 보다 적합하다. 이 연구에서는 한계상태 해석법을 이용하여 건식법(dry construction)으로 축조된 우리나라 석조 홍예아치교의 구조적 거동을 살펴보고, 이 결과를 구조적 안정성 평가시스템 개발에 이용하고자 한다. 이 연구결과는 우리나라 석조 홍예아치교의 구조적 거동을 이해하는데 도움이 되며, 향후 문화재 유지관리 측면에서 공학적 판단기준을 주리라 기대한다. Masonry structures that are very strong in compression fail due to the instability of structural shape of geometry rather than the material stress limit. Considering such structural behavior, the use of the limit theorem that focuses on structural collapse mechanisms is more appropriate for the evaluation of the structural safety of stone voussoir arch bridges. This paper is to investigate structural performance of the stone arch bridges constructed using dry construction method in Korea based on the limit theorem and to exploit the result to develop a system for an structural safety margin. It is expected that this study will help us understand structural behavior of stone voussoir arch bridges in Korea. Also, it will provide a guideline to make engineering decision from the viewpoint of the maintenance of cultural heritages.

People who were exposed to chronic interpersonal traumas in their early life consistently demonstrate complex psychological disturbances and many of them meet the criteria for proposed diagnosis of complex posttraumatic stress disorder (complx PTSD). The author reports a case of the successful sequential integrative treatment mainly composed of eye movement desensitization and reprocessing (EMDR) in a complex PTSD patient. The patient did not respond to the previous treatment with psychotropic medications and supportive psychotherapy. Twelve sessions of EMDR and three sessions of supportive psychotherapy were done for the patient. Psychological assessments were performed before starting the treatment and a week after completing the treatment. After the treatment, the patient improved on all the psychological scales and behavioral measures. This case suggests that the sequential integrative treatment mainly composed of EMDR may be effective for complex PTSD patients.

The purpose of this study is to compare the perceptions and needs for nutrition education between early childhood teachers and parents. This data will address the effective plans and suggest further nutrition education programs for early childhood education centers. This study was conducted with 200 early childhood teachers and 174 parents in Busan. We collected data through questionnaires from teachers and parents and then computed the frequency and ${\chi}^2$ test to analyze the data. The questionnaire was revised and complemented on the basis of related literatures and previous researches. According to our results in this study, there was a significant difference between the teachers' and parents' perceptions on the need of nutrition education and the reason for needing nutrition education. And there were differences among aims, contents, methods, and effective ways of nutrition education for children. In addition, there was a significant difference among the needs from teachers and parents on nutrition education. Finally, the results of this study suggest various implications for developing nutrition education programs in early childhood education centers. These results can be used to develop nutrition education program by considering the teachers' and parents' perceptions and needs. These may be useful data when planning for the nutrition curriculum in early childhood education centers.

ATM-GFR 서비스에서 동적 임계치를 이용한 공평성 향상 알고리즘

김남희,김변곤,Kim, Nam-Hee,Kim, Byun-Gon 한국정보처리학회 2003 정보처리학회논문지 C : 정보통신,정보보안 Vol.10 No.3

ATM 망에서 ABR(Available Bit Rate) 서비스 이상으로 단순한 구현을 통해 대역폭 보장을 만족할 수 있는 다양한 GFR(Guaranteed Frame Rate) 구현의 성능에 대한 연구가 이루어지고 있다. GFR 서비스에 있어서 서비스 품질보장을 만족시키기 위한 중요한 요소 중의 하나는 버퍼관리이다. 즉 ATM 스위치에서 untagged된 셀에 대해 MCR(Minimum Cell Rate)을 보장하기 위해서는 효율적인 버퍼관리가 필요하다. 본 논문에서는 GFR 서비스 보장을 위한 버퍼관리 기법을 제안하고 시뮬레이션을 통해 성능을 평가하였다. 제안된 기법은 각 VC간의 공평성을 보장하기 위해 버퍼에서 셀 폐기를 제어 할 수 있도록 하였으며, 기존의 방식인 Double-EPD(Early Packet Discsrding) 및 DFBA(Differential Fair Buffer Allocation) 기법과 비교하였다. 시뮬레이션 결과 제안된 기법이 기존의 기법에 비해 goodput 및 공평성지표면에서 향상되었음을 확인하였다. The performance of various GFR implementations has been recently studied due to the interest to provide bandwidth guarantees with a simpler implementation than ABR in ATM networks. One of the important factors is buffer management for guaranteeing QoS in GFR service. An efficient buffer management algorithm is necessary to guarantee MCR for untagged cell in ATM switch. In this paper, we propose and evaluate a buffer management scheme to provide the GFR service guarantees. The proposed scheme can control the cell discarding for fairness in each VC, and compared with Double-EPD and DFBA. Our results show that the proposed buffer management with per-VC queuing achieves significant enhancement on goodputs and fairness index than those of existing methods.
