  • Objective : The purpose of this study was to compare sensory processing ability by smartphone addiction levels in preschool children, and to investigate the correlation between smartphone addiction level and sensory processing ability within smartphone addiction group. Method : The subjects of this study were 324 persons, with 124 persons in the addiction group and 200 in the normal user group. Measurements in this study were a questionnaire about general characteristics of subject, smartphone addiction scale, and short sensory profile. Methods for the data analysis included descriptive statistics, independent t-test, Pearson correlation analysis of SPSS 22.0. Results : There was a significant difference in the total Short Sensory Profile (SSP) score and in all sub-domains between the addiction and normal use groups (p<0.05). In the smartphone addiction group, there was a negative correlation between the SSP total score (r=-.278), auditory filtering (r=-.293), visual/auditory sensitivity (r=-.393) and smartphone addiction level. Conclusion : This study confirmed that there was a difference in smartphone addiction and sensory processing ability between the preschool children addiction and normal use groups. It has been proven that there is an interrelationship between sensory processing ability and smartphone addiction in the addiction group. It is significant in that it provides basic data to prevent smartphone addiction.

  • 작업자들이 현장에서 착용하는 안전모는 안전모 본연의 기능 때문에 통풍의 제한을 받게 된다. 이로 인해 작업자들은 작업 시 많은 땀을 흘리게 되며 작업자들이 흘리는 땀은 머리받침 끈과 머리고정대등에 흡수되어 각종세균을 번식하게 되고 이로 인해 냄새가 나게 된다. 최근 들어 원적외선 방사율이 뛰어난 천연소재들이 개발되고 있으며 원적외선은 항균과 탈취능력이 탁월한 것으로 알려지고 있다. 본 논문에서는 상기 나열된 문제점을 해소하기 위하여 상온에서 원적외선 방사율이 높은 소재와 수분의 흡,배출 능력이 뛰어난 소재를 사용하여 안전모내부의 냄새와 세균번식을 줄이는 방안을 제시 하고자 한다.

  • This study investigated the effects of a client-centered vocational rehabilitation program on vocational basic ability, vocational performance ability, and vocational adjustment ability to improve the job competency of adolescents with cerebral palsy. This study was conducted using a multiple intermittent baseline design between the behaviors of individual research subjects from March 19 to August 27, 2018. The subjects for this study were three adolescents with cerebral palsy who were attending special schools in B County in A Province. The intervention program was performed for 40 minutes every Monday and Wednesday, and the vocational basic ability, vocational performance ability, and vocational adjustment ability of the subjects were measured after each session based on the intervention step. As a result, the client-centered vocational rehabilitation program improved vocational basic ability, vocational performance ability, and vocational adjustment ability required by the targeted job for each subject. Therefore, the client-centered vocational rehabilitation program of this study is proposed as a vocational rehabilitation program because it has had a positive effect on job competency by improving the vocational basic ability, vocational performance ability, and vocational adjustment ability of adolescents with cerebral palsy.

  • The clustering environment with heterogeneous workstations provides the cost effectiveness and usability for executing applications in parallel. The load balancing is considered as a necessary feature for the clustering of heterogeneous workstations to minimize the turnaround time. Since each workstation may have different users, groups. requests for different tasks, and different processing power, the capability of each processing unit is relative to the others' unit in the clustering environment Previous works is a static approach which assign a predetermined weight for the processing capability of each workstation or a dynamic approach which executes a benchmark program to get relative processing capability of each workstation. The execution of the benchmark program, which has nothing to do with the application being executed, consumes the computation time and the overall turnaround time is delayed. In this paper, we present an efficient task distribution method and implementation of load balancing system for the clustering environment with heterogeneous workstations. Turnaround time of the methods presented in this paper is compared with the method without load balancing as well as with the method load balancing with performance evaluation program. The experimental results show that our methods outperform all the other methods that we compared.

  • Decrease in crew performance is frequently cited as a major causal factor in maritime accidents. Although considerable researches on working hours undertaken by seafarers have been conducted through interviews and record analyses, experimental studies on 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 managements in the work patterns of their operators. Such tools for mariners would assist shipboard crews, marine pilots, and shore managers for planning and improving work schedules. The overall aim of this paper is to determine a fatigue factor that can be applied to human performance data as a part of a software program that calculates total cognitive performance. This program enables us to establish the levels of cognitive performance in a group of marine pilots in order 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 effects of different work patterns on the cognitive performance of a marine pilot.

  • Mobile manipulator is a robot that has mobility and manipulability with the combination of the task robot and mobile robot. One of the most important feature of the Mobile Manipulator is redundant freedom. Using the redundant freedom, Mobile Manipulator can move various mode, perform dexterous motion. It can have the wider workspace and better performance in avoidance of singularity and obstacle than the fixed base structured robot. Cooperation control using the Mobile Manipulator improves the performance of the robot with redundant freedom in workspace. In this paper, configuration control of the Mobile Manipulator has been studied using Task Segment and TOMM(Task-Oriented Manipulability Measure). For verifying the proposed algorithm, we implemented a mobile manipulator, PURL-II, which is composed of a mobile robot with 3DOF and a task robot with SDOF.

  • 신체 부위를 이용한 Manual Materials handling(MMH) 작업시 무리한 작업하중의 취급으로 인하 여 많은 사고 또는 요통이 발생하기 때문에 작업자의 능력에 맞는 적정 하중에 대한 연구가 필요 하다. MMH작업의 적정하중에관한 연구는 미국 등의 나라에서는 많이 이루어져 왔으나 우리나라에서 는 연구되어 있지 않다. 미국의 경우 NIOSH Guideline을 만들어 MMH시 작업지침으로 활용하고 있으 나 이 지침을 그대로 우리나라에 적용하기에는 신체조건이 달라 우리나라 고유의 연구가 필요하겠다. 적정하중의 연구에는 많은 시간과 경비가 필요하기 때문에 외국의 경우 심리 육체적방법(Psychophysical Method)을 사용하여 시간과 경비를 줄이고도 실제 8시간 작업시의 결과와 비슷한 결과를 얻었다. 본 연구에서는 MMH작업의 적정 하중결정에 있어서 심리육체적 방법을 사용하여 한국인 작업자에 대한 하중과 HIOSH Guideline의 RWL값과의 비교를 하였다. 학생군과 실제 작업자군의 피실험자에 대하여 심리육체적 방법을 적용하여 들기작업을 실험하였다. 6가지 들기 작업을 20분 동안 실시하여 피실험자들이 자신에게 적합하다고 생각하는 적정하중을 측정하였다. 그 결과, 학생군은 RWL값보다 평균 2.5배를, 작업자군은 3.4 배를 적정하중으로 정하였다. 따라서 HIOSH Guideline을 적용한 RWL값은 우리나라 작업자에게는 많은 여유가 있는 하중임을 보여 주었다.
