목적 : 본 연구는 발달성협응장애(Developmental Coordination Disorder; DCD)에 관한 국내 연구동향 및 DCD의 선별이나 중재에 관한 연구결과를 고찰하여 향후 관련 종사자들이 연구를 설계하거나 중재결과를 효과적으로 제시할 수 있도록 기본정보를 제공하고자 한다. 연구방법 : 체계적 고찰방법을 사용하여 1990년 1월부터 2020년 12월까지 국내에서 발행된 논문들 중 발달성협응장애와 관련된 논문을 검색하였다. 검색어는 국내의 연구현황을 확인하기 위해 '발달성협응장애', '발달협응', '발달적 협응'으로 선정하였다. 검색원은 한국교육학술정보원과 한국학술정보, 구글학술검색을 사용하였다. 검색된 4,878개의 논문 중 중복되어 검색된 논문과 배제기준에 해당되는 논문을 제외한 총 17편의 논문이 분석에 사용되었다. 선정된 논문은 DCD연구 중 평가와 중재접근을 분석하기 위하여 Wilson(2005)이 제시한 개념적 모델을 이용하였다. 결과 : 선정된 연구의 질적수준을 분석한 결과에 따르면 두 집단간의 비무작위 연구인 level II가 70%를 차지하였다. 연구설계 시대상 아동의 DCD 유무를 판별하기 위해 Movement Assessment Battery for Children test(MABC)와 MABC Second Edition(MABC-2)(72%)가 운동발달 평가도구로 주로 사용되었다. 중재연구 중 역동체계접근을 적용한 논문은 47%으로 가장 높았으며, 정상발달기술접근의 논문과 인지적 신경과학을 적용한 논문은 각각 18%이었고, 신경발달이론을 적용한 논문은 11%이었다. 정상발달기술접근과 일반적 능력접근을 병행한 논문은 6%로 가장 낮은 사용을 보였다. 이들 논문은 주로 DCD아동들의 운동특성이나 운동(체육)프로그램의 중재효과에 관한 것이었다. 결론 : 국내에서 진행된 DCD관련 연구는 대부분 DCD의 움직임 특성을 설명하거나 운동 중재프로그램의 효과성을 설명한 연구가 주류를 이루었다. 향후 DCD 연구에서는 국내 실정에 적합한 평가도구들의 타당성에 관한 연구와 재활 분야에서 사용하고 있는 다양한 중재접근의 효과를 입증하여 DCD 아동의 운동협응을 향상시키기 위한 시도가 필요하다.

This study investigated the effect of a load of 15% body weight on trunk, pelvis and hip joint coordination and angle variability in subjects with and without chronic low back pain (CLBP) during an anterior load carriage task. Thirty volunteers participated in the study (15 without CLBP, 15 with CLBP). All participants were asked to perform an anterior carriage task with a load of 15% body weight. The outcome measures included the means and standard deviations for measurements of three-dimensional coordination and angle variability of the trunk, pelvis and hip joint. As CLBP patient group .06, control group .70, the correlation coefficient between the groups showed a significant difference only in trunk-pelvic in the sagittal plane (p<.05). Angle variability of CLBP patient group increased significantly in the trunk in frontal plane, the pelvis in all sagittal plane, frontal plane, transverse plane, and the hip in sagittal plane, the hip in frontal plane than angle variability of control group (p<.05). This results mean that the CLBP patient group showed a disconnected coordination pattern in the trunk-pelvis in the sagittal plane, an increased pelvic angle variability in all three planes, and hip angle variability in the sagittal, and frontal planes. The CLBP patient group may have developed a compensatory movement of the pelvis and hip joint arising from the changed stability due to the abnormal coordination patterns of the trunk-pelvic in the sagittal plane. Therefore, CLBP symptoms can potentially worsen in the pelvis and adjacent hip joint in CLBP patients who perform weight-related behaviors in their daily lives. Further research is needed to determine the three-dimensional characteristics of the electromyography and neuromuscular aspects of subjects with CLBP.

본 연구는 예비초등교사들이 과학탐구를 수행하고 이에 대한 과학글쓰기를 분석하여 증거와 이론의 조정의 유형과 특성을 탐색하기 위한 연구이다. 본 연구에서 4개의 과학탐구활동에서 총 115개의 예비초등교사들의 글쓰기가 수집 및 분석되었다. 글쓰기 분석을 바탕으로 4개의 이론과 증거의 조정 유형을 발견할 수 있었다. 본 연구는 다음과 같이 유형을 제안한다. 유형1은 증거와 이론의 일치, 유형2는 증거와 이론의 일치 및 이론의 확장과 정교화, 유형3은 증거와 이론의 불일치, 마지막으로 유형4는 증거와 이론의 불일치 및 조정으로 보았다. 본 연구결과 우선 빈도수를 고려할 때 가장 많은 것에서 적은 것의 순으로 보면 유형1, 유형3, 유형2, 유형4의 순이다. 가장 빈도수가 높은 것으로 유형1이 나왔는데 이는 탐구질문에 내재된 이론이 참여자에 의해 쉽게 파악되었고 이를 지지하는 증거를 발견된 자료 중에서 골라냈다는 것으로 해석된다. 탐구주제와 조정유형의 빈도수 사이에 관련성이 별로 없었으나 예외적으로 활동1은 관련성을 보여주었다. 본연구의 이러한 결과는 학생들이 자신이 이미 가지고 있는 지식을 실험계획, 자료분석 및 해석 그리고 과학주장을 만들어내는 과정에서 잘 융합하고 있다는 점과 연관성이 있다고 보여진다.

We modify ZnO nanorods with Zn-porphyrin to obtain the improved characteristics of energy transfer, which is further investigated for the applicability to photovoltaic devices. A nitrogen heterocyclic ligand containing a thiol group is covalently grafted onto the surface of finely structured ZnO nanorods with a length of 50-250 nm and a diameter of 15-20 nm. Zn-porphyrin is then attached to the ligand molecules by the mechanism of metalligand axial coordination. The resulting energy band diagram suggests that the porphyrin-modified ZnO nanorods might provide an efficient pathway for energy transfer upon being applied to photovoltaic devices.

Effective management of business processes is a crucial issue to every enterprise in e-business environment. What's needed is a new framework of applications that can automatically manage distributed and heterogeneous business processes that span multiple functions of a company. In this paper, we propose technical design of a new enactment model that can coordinate such business process that involves multiple functional units or even multiple companies. In our approach, a process model is decomposed into several structural units, called 'process block', according to their procedural characteristics. Each of them is controlled by autonomous enactment units that can communicate with each other using a mutually agreed coordination protocol. The protocol takes the use of 'associative communication' concept, which allows the autonomy for each unit and secure the correctness of process execution.

The cerebral microvessels possess barrier characteristics which are tightly sealed excluding many toxic substances and protecting neural tissues. The specialized blood-neural barriers as well as the cerebral microvascular barrier are recognized in the retina, inner ear, spinal cord, and cerebrospinal fluid. Microvascular endothelial cells in the brain closely interact with other components such as astrocytes, pericytes, perivascular microglia and neurons to form functional 'neurovascular unit'. Communication between endothelial cells and other surrounding cells enhances the barrier functions, consequently resulting in maintenance and elaboration of proper brain homeostasis. Furthermore, the disruption of the neurovascular unit is closely involved in cerebrovascular disorders. In this review, we focus on the location and function of these various blood-neural barriers, and the importance of the cell-to-cell communication for development and maintenance of the barrier integrity at the neurovascular unit. We also demonstrate the close relation between the alteration of the blood-neural barriers and cerebrovascular disorders.

Distance relaying is one of the most commonly used protection schemes in the high voltage transmission systems. In this scheme, coordination between the primary and backup relays is very critical for the power system security. This paper reports an rule-based methodology for checking and correction of miscoordination problems in the distance relaying. Diagnosis rules achieving an accurate but simple checking have been developed through the geometric analysis of the impedance characteristics of the distance relays. Heuristic rules having the pratical power for miscoordination correction are suggested. The proposed method has proved very effective through the several case studies on the actual systems.

The purpose of this study was to analyze the factor of fashion behavior and to identify fashion behavior differences according to demorgraphic/physical characteristics and parents' background of male college student in Dalian, China. The data were collected via a self-administered questionnaire from 250 male college students living in Dalian, China in June 2007. Data analysis method were used to Crombach's a, reliabilty, factor analysis, frequency analysis, ANOVA, and Sheffe's test for the post hoctest. The results of this study were as follows: Fashion behavior factors were analyzed into 6 factors such as fashion satisfaction oriented, high price oriented, fashion leader oriented, practical fashion oriented, others defendence oriented. There were significant difference in demographic variables such as age, major and physical variables such as height, weight, clothing size and parents' background such as education, job, and income.

This paper presented an experiment which examined eye and hand movement characteristics of novice and experienced workers in the press operation. Continuous recordings of eye and hand movements were made on five novice operators and five experienced operators in press operation. Significant difference between the novice and the experienced operators was observed in eye fixation time, eye movement patterns, hand dwell time, and eye-hand coordination. Also, differences were observed in spatial distribution of eye fixations during the die-closing portion of a stroke. There were no significant differences between the novice and the experiencedoperators in the eye and the hand movement time. The results could be used to establish a guide determining the method and training period to train the novice operators.
