Work delay is one of the facts that make the reliability of construction projects decrease. Therefore, it is important to classify and prioritize the delay factors. This research analyzed key delay factors in apartment house construction through survey. The results of analysis are as follows. (1) Insufficient work force is the key delay factor in structural and finish work. (2) Improper craft of worker is the key delay factor in electrical work. (3) Incompletion of proceeding work is the key delay factor in mechanical work.

Numerosity perception is considered as an innate ability of human being where its sensivitiy may widely vary across each individual person. The present study explored the relationship between visual working memory (VWM), visual search efficiency, and numerosity sensitivity. To accomplish this, we calculated each participant's K-value from change detection performance representing one's storage capacity in VWM, slopes of search RTs representing the search efficiency, and discrimination sensitivity for a quantity difference across two sets of dot arrays representing the numerosity sensitivity. The correlational analysis across the measurements revealed that participants with a high VWM capacity better discriminated the numerosity difference in the arrays when the spatial information in the two dot arrays was preserved. In contrast, the participants with high search efficiency discriminated better the difference in the arrays when the spatial information in the arrays was not preserved. The results indicate high VWM-capacity individuals were presumably able to use a strategy of storing the dot arrays by grouping them into a smaller pattern of dot arrays while high search-efficiency individuals were able to use a strategy of rapidly switching their focused attention across the dots in the arrays to count each individual dot. These in sum suggest that individual differences in numerosity sensitivity rely on one's working memory capacity as well as their efficient use of switching focused attention.

Objective : This study was adapted into Korean for domestic use of the Sensory Processing and Self-Regulation Checklist (here in after referred to as SPSRC) and verified its content validity. Methods : The Korean version of the SPSRC, which was completed via a translation, content suitability, reverse translation, expert committee review, and content understanding process, was presented to three professors of the Department of Occupational Therapy and seven occupational therapists to confirm the content validity. Results : The content validity index (CVI) of the Korean version of the SPSRC was 0.9 or higher in all 130 items. Additionally, the CVI of all items was also 0.99, showing a high level of content validity result. Conclusion : The Korean version of the SPSRC was confirmed to have high content validity as a tool that can measure children's sensory processing ability and self-regulation ability together. The Korean version of the SPSRC facilitates the understanding and evaluation of children's sensory processing and self-regulation abilities in the clinical field, and is thought to be used to establish an intervention plan.

Objective : The purpose of this study is to investigate the effect of mental practice on increasing balance and fall index & fall efficacy scale of persons with post stroke. Method : As a single subject research design with multiple baseline across individuals, the patients were four stroke patients, employed in this study. The employed program included receiving mental practice, and measuring balance score changes using FRT for 4 weeks, including baseline and intervention periods. The subject's fall danger were measured by Fall Index Test(Tetrax) and Fall Efficacy Scale for balance ability were analyzed. The analyses were performed using visually and Two Standard Deviation Band Method. Result : Using FRT, the participants improved their standing balance. During the intervention periods, Their improvement of balance skills results in decreasing Fall Index increasing Fall Efficacy. Conclusion : As a result of this study, mental practice can be an effective method to improve the balance of stroke patien.

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.

Reduced crew performance is frequently cited as a major causal factor in maritime accident causation. Although considerable research has been conducted on the hours of work undertaken by seafarers through interviews and the analysis of records, experimental studies to observe the effects of factors such as high workload, shift patterns, stress, sleep deprivation and disturbance on the cognitive performance of mariners have been limited. Other safety-critical transport industries, such as aviation and rail, have developed fatigue management tools to help manage the work patterns of their operators. Such a tool for mariners would assist shipboard crew, marine pilots and shore management in planning and improving work schedules. The overall aim of this paper is to determine a fatigue factor, which can be applied to human performance data, as part of a software program that calculates total cognitive performance. This program enables us to establish the levels of cognitive performance of a group of marine pilots to test a decision-making task based on radar information. This paper addresses one of the factors that may contribute to the determination of various fatigue factors: the effect of different work patterns on the cognitive performance of a marine pilot.

경영혁신 작업에 대한 연구는 대부분 기술적인 측면과 전략적인 측면이 강조되어 왔고 혁신적인 업무처리 과정에 효율적으로 적응하기 위한 기업의 환경에 대해서는 종종 무 시되어 왔다. 본 연구에서는 경영혁신 작업에 영향을 주고 있는 조직·관리적인 요인을 바탕 으로 기존 연구된 한국 및 미국의 핵심 성공요인을 비교 기술한다. 또한, 한국 및 미국기업 경영혁신 작업의 성과를 비교한다. 분석에 사용한 성과 요인들은 업무처리 시간의 단축, 업 무처리 비용의 감소, 직원들이 기술력이나 업무처리 능력의 향상, 양질의 생산처리, 직원들 삶의 질 향상, 고객 만족도 향상 및 요구변화에 대한 적응력 등이다. T-test를 이용하여 분 석한 결과, 모든 작업성과에 대해 미국기업이 한국 기업보다 높게 나타났다. 이러한 결과는 한국 기업의 경영혁신 과정은 불필요한 업무들을 과감히 폐기한 후 창의적인 업무처리 과정 의 재설계가 필요하다고 판단된다.

본 연구는 시스템의 신뢰도(reliability)를 향상시키기 위해 사용되는 이중(Duplex) 시스템에서 EMI(전자기파 간섭현상) 같은 원인에 의한 동시 발생적(coincident) 고장의 영향을 최소화하는 기법을 제안하고 신뢰성 있는 고성능 컴퓨터를 위한 운영체계 및 H/W 구조의 설계와 최적 평가에 기여하는데 그 목적이 있다. 이중 시스템에 동시 발생적 고장이 일어나면 두 개의 모듈이 고장의 영향을 받게 되므로 고장 포용능력을 상실하게 된다. 이 같은 영향을 최소화하기 위해서 같은 작업들을 가능한 한 다른 시간대로 중복 수행하도록 시퀀싱(sequencing) 및 스케줄링(scheduling) 함으로써 동시발생적 고장으로 야기되는 전체 작업의 고장 결과를 피할 수 있다 또한 실시간 시스템에서 작업들은 기본적으로 수행이 완료되어야 할 시간적 제약(hard deadline)을 지니고 있으므로. 이러한 엄격한 마감시한 내에서 모든 작업을 완수하고 기본조건을 만족시키고자 한다.
