본 연구에서는 소방용 보호장구의 무게가 소방공무원의 신체활동능력에 미치는 영향을 조사하여 소방공무원의 안전을 위한 기초자료 제공을 목적으로 하며 연구에서 얻어진 결과를 제시하면 다음과 같다. 최대 지친상태 도달시간은 소방용 보호장구의 무게와 같은 웨이트 자켓을 입은 경우가 체육복을 착용한 경우보다 18.8% 짧게 나타났다. 최대산소섭취량($VO_2max$)은 체육복을 착용한 경우가 웨이트 자켓을 입고 신체활동을 수행할 때보다 17.6% 증가하였다. 최대심박수(HRmax)는 체육복을 착용한 경우가 웨이트 자켓을 입고 신체활동을 수행할 때보다 5.4% 높게 나타났다.

Purpose: To investigate the effect of an augmented reality (AR) system on muscle strength and function level of the paretic lower limb and the balance ability in the early rehabilitation program of acute stroke patients. Methods: The participants (30 or fewer days after stroke) were randomly assigned to receive intervention with an early rehabilitation program using an AR system (n=1) or an early rehabilitation program consisting of functional electrical stimulation and tilt table use (n=1). Patients in both subjects received interventions 4-5 times a week for 3 weeks. Results: In the paretic limb muscle strength, AR subject was increased from 15 to 39.6 Nm and Control subject was increased from 5 to 30.2 Nm. The paretic limb function of AR subject motor function was increased from 8 to 28 score and Control subject motor function was increased from 6 to 14 score. But sensory function was very little difference between the two subjects (AR subject: from 4 to 10 score, Control subject: from 3 to 10 score). In the balance ability, AR subject had more difference after intervention than control subject (AR subject: 33 score, Control subject: 22 score). Conclusion: The early rehabilitation program using the AR system showed a slightly higher improvement in the motor function of the paretic lower limb and balance ability measurement than the general early rehabilitation program. The AR system, which can provide more active, task-oriented, and motivational environment, may provide a meaningful environment for the initial rehabilitation process after stroke.

Background and Purpose : Many Physical therapist are inclined to communicate less effectively each other because they hardly use the standard terminology. The purposes of this case report are (1) to apply ICF-based documentation in evaluation (2) to submit the strategy of intervention process to improve the ability of walking short distance of the client who has post-stroke. Description : The client was 44-years-old man with hemiplegia who was in 1 month post-stroke problems were diagnosed while applying the ICF core set. The goals agreed with client were independently walking short distance, stairs and obstacles. To come up with the intervention strategy, hypothesis was set and 4 weeks of intervention was carried out after proposing the short goal and detailed purpose. Outcome : The client's performance in walking short distance and confidence were increased after impairment focused intervention, that are improved in walking velocity, endurance, supporting ability in lower limbs, rhythmical movement in upper limbs and the coordination of both limbs. Activities focused intervention also enhanced the ability in climbing steps and walking around obstacles. Conclusion : The decided hypothesis and goal that are to solve the problems the client faced were remarkably meaningful.

Objectives : The purpose of this study is to compare the ability of facial affect perception among schizophrenia patients, their first degree relatives, and normal control subjects. Methods : Thirty five patients with schizophrenia, 22 first degree relatives, and 34 normal control subjects were recruited in this study. All three groups were matched for age and education levels. The facial affect identification test(FAIT), and neurocognitive test were applied. In the FAIT, the correct response rate, perceived intensity, and sensitivity for 6 kinds of affects were compared among three groups. Results : We found that correct response rate of sadness and anger were decreased in the schizophrenia patients compared with the normal control group. Also the schizophrenia patients showed reduced sensitivity for all six affects compared with the normal control group. The ability of facial affect perception in first degree relatives of schizophrenia patients was decreased but there were not any significant differences compared with normal control group. Conclusion : This study confirmed significantly reduced ability of facial affect perception in schizophrenia patients compared with normal control. Decreased ability of facial affect perception in first degree relatives suggests that affective sensitivity can be influenced by genetic predisposition.

천연세라믹, 옻칠, 그리고 고무의 전파흡수능을 조사하였다. 천연세라믹은 2.5GHz~4.5GHz의 주파수 범위에서 2.5dB이상의 전파흡수능을 나타내었으며 옻칠의 전파흡수능이 기존에 전파흡수체의 지지재로 이용되는 고무에 비해 우수한 전파흡수능을 갖고 있음을 확인하였다. 페라이트에 옻칠을 지지재로 이용한 전파흡수체에 대하여 시뮬레이션 한 결과 0.5GHz~10GHz의 주파수 범위에서 16dB 이상의 우수한 전파흡수능을 나타내었다. 따라서 기종에 지지재로 이용하던 고무대신 본 연구에서 새롭게 제안하는 옻칠을 전파흡수체의 지지재로 이용하는 것이 광대역에서 우수한 전파흡수체를 얻을 수 있을 것으로 예상된다.

Fused deposition modelling(FDM) is a rapid prototyping(RP) process that fabricates part layer by layer by deposition of molte thermoplastic material extrude from a nozzle. RP system has benefits. Benefit would be the ability to experiment with physical objects of any complexity m a relatively short period of time. But it has a matter of surface roughness and geometric accuracy. We study on Influence of tangent line angle on surface roughness at fused deposition.

What I would like to expect about this mater is that Korea would develop unique techniques of the waste water which are most suitable to social and other relevant conditions of that country, not entirely following models of sewerage construction of U.S.A. or European countries or Japan. Some cements will be made in the followings: (1) The investigation for the diffusion of seperated simple public sewerag, not the large scale sewerage treatment plant. (2) The plan for non-mixed treatment of lining waste water and industrial waste water. (3) Suggestion for "a man of ability" at the university education to cultivate a technologist of facilities and the elemental watchman at the sewerage maintenance.

현재의 컴퓨터 교육은 정보화 사회에 필수적으로 필요한 문제해결능력을 키우기 위해 정보교과의 대부분을 차지하던 소프트웨어 활용 중심의 내용을 대폭 축소하고 컴퓨터 과학의 원리에 대한 교육을 강화되고 있다. 이러한 문제해결력을 키우기 위하여 개정된 ICT 운영지침의 컴퓨터 과학 원리에 대한 교육 내용 분석을 통한 알고리즘적 사고 문제 모델을 초등 수학과에 접목시켜 다양한 학습 문제해결 실습을 통하여 알고리즘적 사고 신장의 적합성을 검증 하고자 한다.

Human body sways continuously to maintain balance during upright stance. A computer-aided instrumentation system using a force platform has been developed to investigate the body balance. The Kistler force platform and amplifiers were only used to obtain the precise measurements, and the data acquisition and analysis software operating on an IBM PC with A/D converter was developed. This study presents methods for the display of platform center of pressure data on stability study. This system can be used as a tool in evaluating the man's ability to balance and disorders of the nervous system.

본 연구는 중요시설 보안검색에서 기초가 되는 X-ray검색에서 판독요원들의 판독능력 향상 방법에 대한 연구를 목적으로 한다. 특히 색상과 구조로 판독하는 지금의 방법에서 대부분 폭발물에 대한 기초지식만으로 판독이 진행되고 있어 폭발물의 구조이해의 필요성을 강조하고 폭발물의 구조이해가 X-ray 판독능력 향상에 도움이 될 것이라는 가설을 설정하여 연구 과제를 도출하고 있다.
