현재 인간시각의 모델에 관한 많은 연구가 진행중이다. 본 논문에서는 형태정보의 영역대비를 강조하는 무축삭세포의 기능을 반영한 계산론적 망막모델을 제안한다. 무축삭세포는 전달된 물체의 운동정보의 변화를 감지하는 기능을 가지며, 그 감지된 정보를 강조하는 기능이 있다. 본 논문에서는 양극세포에서 출력된 형태정보의 영역대비를 강조한 계산론적 망막모델을 구현하였다. 실험에서는 양극세포의 결과 영상과 무축삭세포의 기능을 처리한 결과영상을 비교하였다. 따라서 무축삭세포의 영역대비 기능을 구현함으로써 대뇌피질에서는 영상의 정보를 효율적으로 처리할 수 있다.

There are efforts to optimize costs and maximize effectiveness of sports events with changing cognition. Proper organizational structure can be initiative to do these, so there are necessities of propose functional areas at the management perspective. With these background, the purpose of this study is to classify functional areas of Olympic at the management aspect. For this purpose, this study conduct four steps delphi research with total 7 experts. First step, experts conduct categorizing and itemizing based on 69 functional areas of 2016 Rio Olympic. Second step, experts provide opinion about first step results and third step, experts propose their point of view regarding to core issues. Fourth step, experts conduct group discussion for drawing final results.

In this research, in order to obtain teaching/learning implications for effective use of questions when teaching number and operation area, the types of questions presented in chapters of number and operation area of 2015 revised elementary math textbooks and the function of questions were compared and analyzed by grade cluster. As a result of this research, the types of questions presented in chapters of number and operation area showed a high percentage of occurrences in the order of reasoning questions, factual questions, and open questions not calling for reasoning in common by grade cluster. And reasoning questions were predominant in all grade clusters. In addition, in all grade clasters, the proportion of questions acting as a function to help guess, invention, and solving problems and questions acting as a function to help mathematical reasoning were relatively high. As such, it can be inferred that the types and functions of the questions presented in chapters of number and operation area are related to the characteristics of the learning content by grade cluster. This research will be able to contribute to the preparation of advanced teaching/learning plans by providing reference materials in the questions when teaching number and operation area.

Purpose : To evaluate the usefulness of functional MR imaging (fMRI) for language mapping and determination of language lateralization. Materials and Methods : Functional maps of the language area were obtained during word generation tasks and decision task in ten volunteers (7 right handed, 3 left-handed). MR examinations were performed at 1.5T scanner with EPI BOLD technique. Each task consisted of three resting periods and two activation periods with each period of 30 seconds. Total acquisition time was 162 sec. SPM program was used for the postprocessing of images. Statistical comparisons were performed by using t-statistics on a pixel-by- pixel basis after global normalization by ANCOVA. Activation areas were topographically analyzed (p>0.001) and activated pixels in each hemisphere were compared quantitatively by lateralization index. Results : Significant activation signals were demonstrated in 9 of 10 volunteers. Activation signals were found in the premotor and motor cortices, the inferior frontal, inferior parietal, and mid-temporal lobes during stimulation tasks. In the right handed seven volunteers, activation of language areas was lateralized to the left side. Verb generation task produced stronger activation in the language areas and higher value of lateralization index than noun generation task or decision task. Conclusion : fMRI could be a useful non-invasive method for language mapping and determination of language dominance.

Objective : The purpose of this study was to provide for the intervention and outcome measurement tools of children with Attention Deficit Hyperactivity Disorder (ADHD) through ICF model. Methods : The systematic review methods were used. Papers published in the journal between January, 2000 and July, 2014 were searched through MEDLINE/PubMed, Sciencedirect, Ovid. The main terms searched were 'ADHD, Children, intervention, outcome measure', and 8 papers were analyzed. Results : 1. The subjects of ADHD were pure ADHD (75.8%), ADHD with dyslexia (9.1%), ADHD with conduct disorder (5.8%), ADHD with tic disorder (3.8%), ADHD with DCD (3.0%), ADHD with emotional disorder (2.5%). 2. The nonpharmacologic intervention of ADHD were functioning and disability (80%) and contextual factors (20%). Most frequently used intervention were body function and structure (60%). 3. The outcome measurement tools of ADHD were functioning and disability (80.5%) and contextual factors (19.5%). Most frequently used outcome measurement tools were body function and structure (70.8%). Conclusion : This study can provide information on the intervention and outcome measurement tools of ADHD.

목적： 기능적 자기공명영상을 이용하여 숫자 연산과 연관된 뇌영역을 알아보고자 하였다. 대상 및 방법： 정상 성인 자원자 6명을 대상으로 연산과제를 이용하여 연산과제와 관계된 대뇌영역 꼭 활성화를 유도하였다. 실험은 실험 I과 실험II로 나누어 진행하였다. 실험 I에서 연산과제는 스크린을 통해 보여주고 계산식이 맞는지를 판단하여 신호하도록 하였고[예：(4＋5)$\times$8=72], 대조과제는 십자모양을 집중하여 보도록 하였다. 실험II에서 연산과제는 실험 I과 동일하였고, 대조과제는 화면에 제시되는 세 개의 수가 모두 홀수 또는 짝수일 때 신호하도록 하였다. 기능적 자기공명영상은 1.5T 초전도 자기공명영상장치에서 EPI BOLD 기법을 이용하여 얻었으며 6명에서 얻은 영상을 정상화(normalize)한 후 SPM 프로그램을 이용하여 통계분석을 하였다. 활성화된 뇌 영역은 모형뇌에 지도화하여 두 과제에서 활성화된 뇌 영역을 비교 분석하였다.

The purpose of this study was to extract and validate the educational goals and the subjects for developing a music gifted curriculum. Based on literature review and analysis of music gifted curricula in foreign countries, 19 educational goals and 18 subjects were derived from literature review and analysis of music gifted curricula in foreign countries. To validate the educational goals and the subjects, delphi survey was carried out twice with 26 expert panelists in the field of music, music education and music gifted education. Delphi survey was analyzed using the mean, content validity ratio, and the degree of consensus. The final set of educational goals for music gifted education included 6 skills related goals, 4 creative expression related goals, 4 knowledge related goals, and 2 attitude related goals. The final set of subjects included 4 major-specific subjects, 5 foundational subjects, 4 theory-related subjects, 3 integration and social participation related subjects. The results of this study can be used as baseline data to develop a music gifted curriculum by providing ideas for deciding what to teach and why to teach in music gifted education.

본 논문은 뇌기능 연구에 크게 기여하는 기능적 자기공명영상을 효과적으로 분석하기 위한 유효 연결성(Effective Connectivity, EC)을 이용한 대규모 네트워크(Large-Scale Network, LSN) 분석(LSN-EC)을 제안한다. 유효 연결성은 뇌영역간의 시공간적 인과관계를 표현한 연결성이며, 뇌의 기능적 연결성 및 구조탐색 사용된다. LSN-EC는 뇌영역간의 EC를 표현하고 그룹간의 차이분석을 통하여 뇌질환 분석 및 진단 연구로의 응용이 가능하다. 실험결과에서 알츠하이머병과 관련이 높다고 알려진 후대상피질(Posterior Cingulate Cortex)과 해마(Hippocampus)가 포함된 변연엽(Limbic Lobe), 기저핵 및 시상(Basal Ganglion and Thalamus) 주변 영역에서 감소된 EC를 확인하였다.

USN과 BcN은 모두 별개의 기능적 특성을 갖는 네트워크들을 지칭하고 있지만, 그 네트워크를 이용한 서비스를 실현하기 위한 상위 기능요소 및 각 요소간의 관계를 포괄하기도 한다. 그럼에도, USN 영역에서는 BcN을 높은 성능의 장거리 전달 망으로 보는 시각이 지배적이며, BcN 영역에서는 여러 종류의 가입자망 중 하나로 USN을 인식하고 있어, 둘 간의 체계적 연동을 어렵게 하고 있다. 본 논문에서는 두 서비스 제공구조의 분석을 통하여 일반화를 수행하고, 정의된 모델에 필요 기능을 할당한 후 각 기능간의 연동방식에 관하여 논함으로써, USN과 BcN 두 영역의 컨버전스를 실현할 수 있는 서비스 구조를 제안한다.
