모바일 헬스케어의 기본 개념은 '치료'가 아닌 '관리'에 있다. 심박수 측정으로 내가 가진 운동 능력을 얼마나 사용하고 있는지 또는 얼마나 사용할 것인지 조절할 수 있고 자신에게 필요한 운동을 맞춤형식으로 조절이 가능하다. 선행연구에서 다뤘던 심박수 구간별 3대 영양소 연소 비율을 통해 다이어트를 목적으로 운동을 조절할 수도 있고 근력 강화를 위해 전문 트레이닝을 강행 할 수도 있다. 본 연구에서는 건강관리를 위한 생체신호 측정 센서 기반 스마트 기기로 심장수을 믈루투스를 사용하여 측정하고 이상을 예측 보고할 수 있는 프로토타입을 개발하고, 정성적, 정략정 평가를 설시하였다. 향후, 사용성 평가 결가를 기반으로 도출된 문제점의 수정 보완을 통해 최종 센서기반 스마트 심장박동 관리기를 구성하고자 한다.

Purpose: Eye movements and fixation ability are an important procedure to obtain external information and essential means of clear vision. The purpose of this study was to determine the reading performance such as reading time and number of fixations when random text was viewed at varying distances. Methods: Twenty two presbyopes were participated. All subjects were screened for their suitability to participate in the study by clinical examination, and none of the participants had previously worn contact lenses and no previous experience of wearing any types of presbyopic vision correction except single vision. The reading time and number of fixations were recorded using eye tracker while each subjects was waring four vision corrections which included single vision for distance (SV), bifocal spectacle lenses (BIF), progressive addition lenses (PAL), and monovision (MV). The reading material was presented at distance and near distance. Results: Reading time and number of fixations for near stimulus were significantly different among vision correction used in this study (p<0.001). In particular, wearing SV required longer reading time and produced longer fixation duration for near text. However, reading distance text was similarity performed across vision corrections tested and there was no statistical difference found for either reading time and number of fixations. Conclusions: Wearing presbyopic vision correction is advantageous for reading task of near stimuli, but not having near correction such as wearing SV could result in longer reading time and higher number of fixation due to lacks of accommodative ability for near task. For the future studies, it would be interesting to examine the performance of reading both at adapted and unadapted stages as examining only unadapted wearers was limitation of this study.

Objective : The purpose was the effect of sensory integration therapy combined with an eye tracker on the sensory processing and visual perception of children with developmental disabilities. Methods : It was a single-subject study with a multiple baseline design between subjects, and the intervention applied sensory integration therapy combined with an eye tracker. Visual-motor speed and saccadic eye movements were assessed at each session of baseline and intervention periods. As pre- and post-evaluation, sensory profile, Korean-Developmental Test of Visual Perception and Trail Making Test were conducted. The results of each session evaluation and pre- and post-evaluation researched the effectiveness of the intervention through visual analysis and trend line analysis. Results : As a result of the evaluation for each session, the slope of the trend line for all children in visual-motor speed and saccadic eye movement increased sharply during the intervention compared to the baseline. As a result of the pre- and post-evaluation, the sensory processing of movement, body position, and visual changed from more than that of peers to a level similar to that of peers. In visual perception, all children's ability of Visual Closure increased. As a result of Trail Making Test conducted to confirm the improvement of children's visual tracking and visual-motor abilities, all children showed a decrease in performance time after the test compared to before. Conclusion : It was confirmed that sensory integration therapy combined with an eye tracker for developmental disabilities has effect on sensory processing and visual perception. It is expected to play an important role clinically as it can stimulate children's interest and motivation in line with recent technological improvements and the spread of smart devices.

Objective : To investigate the correlation between relationship ability and ADL performance ability of patients with TBI. Methods : This study was carried out from March 2012 to April 2012 with 20 patients with TBI. Relationship ability assessed using Relationship Change Scale(RCS), ADL performance ability assessed using Functional Independence Measure(FIM). Results : The RCS showed a high level of correlation with marital status and duration of illness. The RCS showed a high level of correlation with the FIM total score and the FIM cognition area. However the RCS did not show a correlation with the FIM motor area. Conclusions : Functional disability of social cognition is a factor that disturbs rehabilitation after TBI and it has a negative influence on the relationship in ADL. If accurate evaluation and treatment on relationship ability after TBI are carried out side by side from the initial stages of onset, we could expect more patients to improve their social cognition and ADL performance ability.

Diadochokinesis (DDK) aims to identify the evaluating the oral mitor ability and the moter coordination ability. There are few DDK normative data on elementary school students in Korea, The purpose of this study was to investigate the characteristics of the speed and regularity of DDK in first- and second-grade students in elementary school. The subjects were a total of 194 students in first- (45 males, 50 females) and second-grade (47 males, 52 females) in elementary schools in Gwangju Metropolitan City. As evaluation tasks, AMR task 'p?', 't?', and 'k?' and SMR task 'p?t?k?' were performed. The speed and regularity of DDK was measured using Motor speech profile (Model 5141, KayPENTAX) and Praat (v6.0.3.6). The results of this study, First, there was a statistically significant difference by grade in AMR speed for 'p?', 't?', and 'k?' and the AMR speed was faster in second grade group. And, there was no statistically significant. Second, AMR regularity showed a statistically significant difference in 'p?', 't?', and 'k?' according to sex and was found to be more regular in female student group. There was no significant difference in regularity by grade. Third, the SMR speed showed statistically significant difference in 'p?t?k?' by grade and was faster in second grade group. And there was no statistically significant difference by sex. The results of this study showed that the DDK performance ability in first- and second-grade students in elementary school was slightly different according to grade and sex. In future research, it is necessary to investigate the correlation between the articulation accuracy and linguistic intelligibility, and to find out the usefulness of DDK in articulation evaluation.

For the design of composite bridge piers, detail requirements for the reinforcements is not clear to satisfy the required seismic performance. Composite bridge piers were suggested to reduce the sectional dimensions and to enhance the ductility of the columns under earthquake loadings. In this paper, five specimens of concrete encased composite columns of 400mm diameter with single core steel were fabricated to investigate the seismic performance of the composite columns. Shaking table tests and a Pseudo-Dynamic test were carried out and structural behavior of small-scaled models considering near-fault motions was evaluated. Test parameters were the pace of the transverse reinforcement, lap splice of longitudinal reinforcement and encased steel member sections. The displacement ductility from shaking table tests was lower than that from the pseudo-dynamic test. Limited ductile design and 50% lap splice of longitudinal reinforcement reduced the displacement ductility. Steel ratio showed significant effect on the ultimate strength. Lap splice and low transverse reinforcements reduced the displacement capacity. The energy dissipation capacity of composite columns did not show significant difference according to details.

Patients with schizophrenia have thinking disorders such as delusion or hallucination, because they have a deficit in the ability which to systematize and integrate information. therefore, they cannot integrate or systematize visual, auditory and tactile stimuli. In this study, we suggest a virtual reality system for the assessment of cognitive ability of schizophrenia patients, based on the brain multimodal integration model. The virtual reality system provides multimodal stimuli, such as visual and auditory stimuli, to the patient, and can evaluate the patient's multimodal integration and working memory integration abilities by making the patient interpret and react to multimodal stimuli, which must be remembered for a given period of time. the clinical study showed that the virtual reality program developed is comparable to those of the WCST and the SPM.

The purpose of this study was to investigate relationships between the appraisal type of competency and aggression in elementary school students. Appraisal type was divided into inflated/deflated ratings. Appraisal type in competencies, and sex were independent variables, and aggression was dependent variables. SPPC, TRS and AS were administered to 419 students and 20 teachers. The major findings of this study were as follows: First, the correlation of child-teacher with perceived competence ratings was the highest in the scholastic competence. Second, frequency of deflated appraisal was the highest in the behavioral conduct. Third, physical aggression is differentiated by the sex. And physical aggression was high when athletic competence was deflated. Fourth, physical aggression, hostility and anger were high when physical appearance was deflated. Fifth, hostility is significantly different by the interaction effect between sex and appraisal type of behavioral conduct. The above findings imply that appraisal type in competencies does not always result in aggression and this study will provide a useful insight for aggression reduction in elementary school students.
