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.

The purpose of this study was to investigate the association between dietary behavior and temperament & character in preschool children, and to offer basic data that can be applied for nutrition education and counseling. A total of 211 parents of preschool children aged 3~5 years performed the Korean version of Preschool Temperament and Character Inventory (K-psTCI), a questionnaire based on Cloninger's seven-factor model of personality, along with a questionnaire about the dietary behaviors of their children. K-psTCI represented seven factors such as harm avoidance (HA), novelty seeking (NS), reward dependence (RD), persistence (P), self-directedness (SD), cooperativeness (CO), and self-transcendence (ST). The subjects were divided into either the high rank group or low rank group based on the mean score of each factor. The high rank group of HA showed significantly less physical activity and less appetite than the low rank group of HA. The children in the high rank of NS were more likely to have picky eating and a late night snack. The children in the low rank of SD or CO were more likely to have undesirable dietary behaviors, such as picky eating, too much snacking, and lower appetite than those in the high rank of SD or CO. In conclusion, individual temperament & character in preschool children may be associated with their dietary behavior, and understanding temperament & character in children may be important facts to screen and to develop an effective nutrition education program for children.

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.

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.

교량설계문제란 주어진 조건을 만족하는 해를 찾아가는 과정이며, 설계결과의 질적 수준은 개념적 설계단계에서 문제의 제약적 조건을 어떻게 합리적 설계대안으로 연계시키는지에 따라서 현저히 달라진다. 이 논문에서는 아름다운 교량형태를 위해서 창의적 사고력을 이용하여 정성적 교량설계 대안을 생성하는 개념적 설계를 위한 교량형태 생성방법에 주안점을 둔다. 이 연구에서 창의력은 무에서 유를 창조하는 것이 아니라 기존 개념들의 재구성을 의미한다. 이러한 창의력은 역학적 힘과 형태와의 관계를 토대로 이루어지는 구조시스템의 생성질서를 확장시키는 것뿐만 아니라, 건축양식과 같은 예술적 요소를 교량설계와 접목하는 것을 포함한다. 또한, 개념적 설계단계에서 교량형태 생성과정에 시각적 구조해석 결과를 보여주는 정력학적 도해법이 매우 효율적임을 살펴본다. 이 연구에서 제시하는 교량형태 생성방법은 실무자들에게뿐만 아니라 미학적 교량설계 교육에 대한 새로운 교육모델로도 사용될 수 있을 것으로 기대한다. Bridge design is a problem-solving process whose level of design quality strongly depends on how to relate design constraints with feasibile design objectives in conceptual design stage. This paper has focused on how to create bridge shapes using creativity toward better looking bridge appearances in conceptual design stage. The term creativity in this study does not refer to the creation of something from nothing but to the reorganization of existing concepts. Such creativity includes not only enlarging the number of structural forms which is established based on the relationship between form and statics but also combining bridge design with artistic components like an architectural style. Also, this study has investigated the usefulness of graphic statics as a structural analysis tool showing the analysis results visually to generate bridge forms in conceptual design stage. It is expected that the proposed way of generating bridge forms in this study to be used not only for practical purpose but also for educational purpose regarding the aesthetic bridge design serving as a new education paradigm.

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.

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.

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.
