This research was intended to provide a basic data on the study of utilization of assistive technology to improve vocational ability for people with intellectual disabilities. As this study was literature review, it was analyzed the qualitative level, methodology contents, and general characteristic of a study, related assistive technology application for improvement of vocational ability in people with intellectual disabilities. The results of this study were as follows; Firstly, experimental environments mostly consisted of separated experimental conditions and design employed multiple probe design; Secondly, all of studies were involved in the standard of selection of subjects, but the proportions of study describing the contents related to subjects was low. The proportions of study describing the behavior-control and exterior-variable control method was low; Thirdly, most study evaluated independent variable and presented fidelity of treatment but, the presentation of social validity was proved to be insufficient. In order to effective application of assistive technology in vocational rehabilitation, it is need a evidence that the application of assistive technology is evidence-based practice in vocational rehabilitation. We also need a supplementation between methodology contents and qualitative level of study in more study.

본 연구는 웨이블릿 변환을 통하여 객체 영상에서 질감 특징 값을 추출하고, 신경망을 계층적으로 구성하여 분류하는 방법을 제안한다. 기존의 신경망을 이용한 영상의 분류는 단일 신경망을 이용하는 것이 대부분이었다. 하지만 단일 신경망은 분류하고자 하는 클래스의 수가 많거나 분류하고자 하는 대상이 유사한 입력패턴을 가질 경우 학습시간이 오래 걸리고, 인식률이 크게 떨어지는 문제를 가지고 있다. 그래서 본 연구에서는 효과적인 객체 영상 분류를 위해서 여러 개의 단일 신경망을 계층적으로 결합하는 방법을 제안한다. 실험결과 분류 대상 클래스가 증가함에도 불구하고 단일 신경망에 비해 학습시간이 단축되고, 높은 인식률을 보여주었다.

Objective : The purpose of this study was to confirm the characteristics and quality of a single-subject research that conducted interventions to improve activities of daily living (ADL) in stroke patients. Methods : 'Stroke,' 'activities of daily living,' and 'single-subject studies' were searched as keywords among papers published in the last 15 years between 2009 and 2023 among Research Information Sharing Service, DBpia, and e-articles. A total of nine papers were examined for the characteristics and quality before analysis. Results : The independent variables applied to improve ADL included constraint-induced therapy, mental practice for performing functional activities, virtual reality-based task training, subjective postural vertical training without visual feedback, bilateral upper limb movement, core stability training program, traditional occupational therapy and neurocognitive rehabilitation, smooth pursuit eye movement, neck muscle vibration, and occupation-based community rehabilitation. Assessment of Motor and Process Skills was the most common evaluation tool for measuring dependent variables, with four articles, and Modified Barthel Index and Canadian Occupational Performance Measure were two articles each. As a result of confirming the qualitative level of the analyzed papers, out of a total of nine studies, seven studies were at a high level, two at a moderate level, and none were at a low level. Conclusion : Various types of rehabilitation treatments have been actively applied as intervention methods to improve the daily life activities of stroke patients; the quality level of single-subject studies applying ADL interventions was reliable.

The purpose of this study was to determine the effect of custom seating system on upper extremity access to mouse for a child with cerebral palsy. A single-subject ABAB design was used with one 13years old participant. The measurements were response time and accuracy of mouse click in the participant's typical position and in an intervention position. The intervention position was taken by using current clinical guideline and research on promoting upper extremity movement. The intervention position was achieved through hands-on postural support to the participant's typical seating. The results of this study were as follow: first, response time was decreased in the intervention position compared with the typical seating. Second, accuracy of mouse click was highly in every phases. So further analyses were not conducted on these data. The results of this study provide empirical evidence of the positive effects of functional seating on access to mouse for children with cerebral palsy. Further research is required to confirm the positive effect of the custom seating system across other disabilities type and more subjects.

우리나라 연근해 어업자원은 어종 수는 많으나 양적으로 뚜렷한 우세종이 없는 것이 특징이며, 어업형태도 복수어종을 대상으로 하거나 단일어종을 복수어업으로 어획하는 것이 대부분이다. 이러한 다종어업에 대하여 단일어종에 대한 자원평가모델을 적용하는 것은 효과적인 방법이 될 수 없다. 따라서, 본 연구에서는 다종자원평가 방법과 관리방안을 모색해 보았다. (중략)

최근 인용 네트워크 분석을 통해서 단일 문헌의 인용 영향력을 측정하려는 시도가 다양하게 전개되고 있다. 널리 알려진 PageRank를 보완하려는 일부 시도와 함께 h-index를 단일 문헌의 인용 영향력 측정에 적용한 단일문헌 h-index도 제안되었다. 이 연구에서는 Web of Science에서 검색한 계량정보학 분야 문헌집합을 대상으로 여러 측정 방식의 특징을 비교해본 후, 새로운 인용지수 2종을 제안하였다. 제안한 인용지수는 PageRank처럼 전역 네트워크 분석 방식인 지수 1종과 h-index처럼 지역 네트워크 분석 방식인 지수 1종으로서 상황에 따라 선택하여 사용할 수 있다.

Objective: The purpose of this study is to investigate the effect of interactive metronome (IM) training on attention among children on the autistic spectrum. Methods: This is a single case study, using ABA design, of one child with autism spectrum disorder (ASD) who had attentional difficulties. A total of 20 sessions were conducted: 3 baseline sessions (A), 14 intervention sessions (B), and 3 follow-up baseline sessions (A'). During the intervention period (B), IM training was performed. Inattention and attention activities were measured as the dependent variables in all three phases (A, B, and A'). Results: Compared to baseline, the subject's inattention decreased in the IM training mediation period, and the performance of activities requiring attention also improved. The intervention effect was maintained even during the follow-up baseline period. Conclusion: The results of this study suggest that IM training positively influences attention among children with ASD with attention deficit symptoms. Further, it provides the clinical basis of IM training as an intervention for children with ASD.

This study identifies the characteristics of recent citation-based indicators for assessing a single paper in the context of their co-relationships. Five predefined indicators were examined with three variants of h-index which are convened in this study; the formers are PageRank, SCEAS Rank, CCI, f-value, and single paper h-index and the latters are $h_S$-index, h1-index, and $h_S$1-index. The correlation analysis and cluster analysis were performed to group the indicators by common characteristics, after which the indicators were calculated with the dataset from KSCI DB. The results show statistical evidence that distinguishes h-index type indicators from others. The characteristics of the indicators were verified with citation frequency factors using correlation analysis. Finally, the implications for applications and further studies are discussed.

In this study, a new keyword extraction algorithm is applied to a single document with term clustering. A single document is divided by multiple passages, and two ways of calculating similarities between two terms are investigated; the first-order similarity and the second-order distributional similarity. In this experiment, the best cluster performance is achieved with a 50-term passage from the second-order distributional similarity. From the results of first experiment, the second-order distribution similarity was also applied to various keyword extraction methods using statistic information of terms. In the second experiment, pf(paragraph frequency) and $tf{\times}ipf$(term frequency by inverse paragraph frequency) were found to improve the overall performance of keyword extraction. Therefore, it showed that the algorithm fulfills the necessary conditions which good keywords should have.

To analyze atmospheric fate of PCBs in the Kanto region, Japan, an one-compartment box model was used and the relationship between behavior of each PCB homologue and air temperature was simulated. In addition, the emission rates and the deposition fluxes in the overall Kanto region were estimated by the model. The total emission rate and deposition flux was 3,320 kg/yr and 1,480 kg/yr, respectively. The contribution of advection was ranged from 22 to 38% among elimination processes(advection, dry & wet deposition and degradation) of PCBs from atmosphere. The rates of degradation(OH radical process) for PCBs in the Kanto region would be negligible. This study showed that one-compartment box model can be available to understand the overall atmospheric behavior of PCBs.
