The purposes of this study were to develop and validate Korean MHBT for identification of giftedness. MHBT in this study consists of KFT-HB and MHBT-5. MHBT-S was composed of 1) space presentation and thinking ability, space perception,. physics/technic tasks 2) affective domain; creativity, achievement motivation, desire of knowledge, social competence questionnaire 3) performance attitude questionnaire 4) interest questionnaire. The subject were 489 middle school students (1 or 2grade) in the education centers for gifted youth and general classes. Except a few subscales, internal consistent reliability was considered good. Korean MHBT discriminated well gifted students from general students in KFT-HB and some subtests of MHBT-5. As results, Korean MHBT in this study was expected to be a reliable and valid instrument for identification of korean gifted students.

Objective : To develop an occupation-based bilateral upper extremity training protocol that can be effectively applied in a medical setting Methods : The research process using the delphi technique was carried out in 3 stages. The first stage was an open questionnaire development stage, The first draft is prepared through literature review and open questions were developed through preliminary research based on the draft. The second stage was the delphi survey. Based on the responses of the experts obtained through the open Delphi survey, the adequacy of the training protocol was shown on a Likert 5 point scale. The items were edited and deleted, reconstructed by analyzing the mean and standard deviation, stability, convergence degree, consensus, and content validity ratio through the questionnaire. The third step was the completion of the protocol. After discussions between researchers, the finalized protocol contents were reorganized to complete the occupation-based bilateral upper extremity training protocol for medical setting. Results : The final protocol consisted of 9 items across 3 areas in the occupation-based intervention selection domain and 81 items across 4 areas in the bilateral upper extremity training domain, intervention period, and evaluation. Conclusions : This study suggests an evidence-based method that collects the opinions of occupational therapists in order to use occupation-based activities as interventions in a situation that currently sees occupational therapy primarily performed in hospitals. It is also meaningful that the bilateral upper extremity training can be applied effectively in clinical situations by concretely presenting.

How to process event message traffic efficiently is important to collaboration among multiple distributed users, and it is a key research issue in the virtual environment fields. AOI model is one of solutions for this problem; which reduces message traffic by restricting event propagation region into an area in which a user is interested. However, in previous systems, it is difficult to adapt to dynamic environment where changes in the number and movement of participants are frequent. This paper proposes a new event management model, called extended AOI model, which is helpful to improve flexibility and efficiency of traditional models, and is able to extend its functions by introducing multi-layered regions. The proposed model can be applied to DVE and MMORPG as an event filtering model.

Objective : To identify the effect of bilateral arm training for activities of daily living(ADL) of the chronic phase after stroke. Methods : 20 patients with stroke, randomized to an experimental group(n=10) and a control group(n=10). Both groups received the usual occupational therapy. In addition, an experimental group received an bilateral arm training, 30-min sessions per a day for 6 weeks. The Functional Independence Measure(FIM) was used to evaluate ADL for both groups. Results : First, there is a significant difference before and after receiving the bilateral arm training(p <.05). Second, there are significant differences in all ADL areas of Self-care, Transfer, Social cognition after bilateral arm training(p<.05). Third, there are significant differences in all sub-areas of Self-care, only stairs of Locomotion, and only Problem solving of Social cognition by comparing sub-areas as bilateral arm activity(before and after) and occupational therapy intervention(before and after). Conclusion : Using bilateral arm training for the chronic phase after stroke improved their abilities of ADL. Therefore, there are an expectation to use bilateral activity training for the chronic after stroke clinically and a need of further study about bilateral arm training related to ADL in the future.

Occupational therapist is required for patient-centered approaches to actively seek the perspectives of patients and their families in clinical settings. The purpose of this study was to investigate the current trends and to suggest future-oriented view of examination and assessment used by neurological occupational therapist in clinical settings. Sixty-six occupational therapists who work in persons with neurological disorders participated in this study. The survey was measured from Seoul and GyeongGi by means of E-mail about commonly used assessment tools and selecting considerations. The participants were 66 neurological occupational therapists. The number of patients by one day was from 10 to 14 persons, and the length of time for initial evaluation was 20-40 minutes per one patient, and reexamination periods was every 1 month or as functional changes were detected. The using tool was not limited only neurological tools, and choice consideration was the reliability and validity of clinical measures. The most frequently used tools for adults were: JHFT for motor function in upper extremity, MMSE-K for cognitive perceptual assessment, MBI for daily activity assessment, and COPM for occupational performance. The most frequently used tools for child were: MVPT for cognitive perceptual assessment and Wee-FIM for daily activity assessment. The results of this study suggest that it is necessary to integrate and associate patient-report, care-giver report, and results of performance-based assessment for estimating plan of care more quality.

In this paper, we investigated the following items for the development of gas safety work mobile app. In this study, which is a follow-up study after the completion of the scenario design and the first, second image extraction of the mobile app based on the initial research that has been studied, 1) Suggested classification of gas works by type classification and risk classification 2) The research and proposal of interaction method for effective interworking of mobile app and worker in many industrial fields of two-hand work have been made. In particular, the development of a mobile app that interacts with the main system that manages not only the gas work but also the field of each industrial field is the first attempt in Korea and has helped the worker to work freely and safely through various interaction methods.

The aim of this study was to identify the type of occupational balance of college students and analyze the differences between positive or negative emotions according to degree of flow. The Experience Sampling Methods (ESM) were conducted for 12 college students using smart phones. As a result, in activities of daily living group, apathy showed the highest percentage (34%) and in over work group, flow showed the highest percentage (41%). In occupational balance group, frequency of labor and leisure activities was high but boredom was experience a lot in leisure activities. When the students experienced flow in main activities, mean score of positive emotions showed the highest value. Through this study, we identified the differences of flow experience in occupational performance based on type of occupational balance and confirmed improvement of positive emotions in activities experienced flow.

In this paper, we suggest a new algorithm applied to the segmentation of published documents to obtain constituent and layout information of document. Firstly, we begin the process of blocking and labeling on a 300dpi scanned document. Secondly, we classify the blocked document by individual sub-regions. Thirdly, we group sub-regions into graphic areas and text areas. Finally, we extract information for layout recognition by using the data. From an experiment on papers of an academic society, we obtain the above 98% of region classification rate and extraction rate of information for the layout recognition.

데이터 마이닝의 방법론 중 클러스터링은 데이터베이스 객체들의 에트리뷰트 값에 근거하여 유사한 그룹으로 식별하는 기술적인 작업이다. 그러나 대부분 알고리즘들은 데이터의 차원이 증가할수록 형성된 전체 데이터 공간은 매우 방대하므로 의미있는 클러스터의 탐색이 더욱 어렵다. 따라서 효과적인 클러스터링을 위해서는 클러스터가 포함될 데이터 공간의 예측이 필요하다. 본 논문에서는 고차원 데이터에서 각 차원에 대한 점진적 프로젝션을 이용한 클러스터링 방법을 제안한다. 제안한 방법에서는 클러스터가 포함될 가능성이 있는 데이터공간의 후보영역을 결정하여, 이 영역에서 점들의 평균값을 중심으로 클러스터를 탐색한다.
