The Comparative Study for Software Reliability Model Based on Finite and Infinite Failure Exponential Power NHPP
Kim, Hee-Cheul ; Shin, Hyun-Cheul ;
The Journal of Korea Institute of Information, Electronics, and Communication Technology, volume 8, issue 3, 2015, Pages 195~202
DOI : 10.17661/jkiiect.2015.8.3.195
NHPP software reliability models for failure analysis can have, in the literature, exhibit either constant, monotonic increasing or monotonic decreasing failure occurrence rates per fault. In this paper, finite failure NHPP models that assuming the expected value of the defect and infinite failures NHPP models that repairing software failure point in time reflects the situation, were presented for comparing property. Commonly used in the field of software reliability based on exponential power distribution software reliability model finite failures and infinite failures were presented for comparison problem. As a result, finite fault model is effectively infinite fault models, respectively. The parameters estimation using maximum likelihood estimation was conducted. In this research, software developers to identify software failure property some extent be able to help is considered.
A Study on Job Stress and Stress Coping Strategies for Administrative Personnel working in Early Childhood Educational Institution - With a Focus on O City, Gyeonsangnam do -

DOI : 10.17661/jkiiect.2015.8.3.203
This study aims to figure out job stress and stress coping strategies for administrative personnel working in early childhood educational institution. The survey was conducted targeting 119 administrative personnel working in early childhood educational institution in Gyeonsangnam-do from September 10th, 2014 to December 20th, 2014. SPSS/WIN 18.0 Program for statistical processing, followed by frequency analysis, t-test, correlation analysis and multiple regression analysis. The result of socio-demographic characteristics had differences by factors ages, marriage status, religion and position. correlation. There was negative(-) correlation between lower variables of advices of experienced, change of problem recognition and lower variables of workload, job performance. Third, frequency of drinking and position at work were confirmed statistically as significant factors in regression model. This study is to be basic data to improve administrative personnel's task working in early childhood educational institution.
Research on agricultural dwelling welfare application plan according to empty house reality condition -Centered on Yeongwol-gun-

This research aims to study agricultural dwelling welfare's application plan according to empty house reality condition. Study's subject was empty houses in Yeongwol-gul in year 2013. Data analysis was concentrated on measuring questionnaires and SPSSWIN 16.0 was used for statistics of frequency analysis and average analysis. As a result, first, empty house's background occurrence and environment was investigated. Second, due to dead mine and rural exodus, there was increase in the number of empty houses, which damaged regional scenary. Furthermore, the region became a crime-ridden district, which is a social issue. Third, it was found that plans as empty house remodeling, policy support, various alternatives, systematic management, housing welfare, and continuous promotion were needed. This research will provide implications in solving social issues due to empty houses, and through application plan, there will be improvement in agricultural dwelling welfare and income increase. There also will be improvement in environment, and policy source for inducing city people and original residents to empty houses.
A Study on Signal Sub Spatial Method for Removing Noise and Interference of Mobile Target
Lee, Min-Soo ;
The Journal of Korea Institute of Information, Electronics, and Communication Technology, volume 8, issue 3, 2015, Pages 224~228
DOI : 10.17661/jkiiect.2015.8.3.224
In this paper, we study the method for desired signals estimation that array antennas are received signals. We apply sub spatial method of direction of arrival algorithm and adaptive array antennas in order to remove interference and noise signal of received antenna signals. Array response vector of adaptive array antenna is probability, it is correctly estimation of direction of arrival of targets to update weight signal. Desired signals are estimated updating covariance matrix after moving interference and noise signals among received signals. We estimate signals using eigen decomposition and eigen value, high resolution direction of arrival estimation algorithm is devided signal sub spatial and noise sub spatial. Though simulation, we analyze to compare proposed method with general method.
Performance Analysis of Electronic Control System for Weeding Implement such as Slope Land
Park, Won-Yeop ; Hong, Sung-Ha ; Lee, Jae Min ; Lee, Sang-Sik ;
The Journal of Korea Institute of Information, Electronics, and Communication Technology, volume 8, issue 3, 2015, Pages 229~238
DOI : 10.17661/jkiiect.2015.8.3.229
This study was conducted to develop electronic control system of weeding implement that can operated at various areas such as slope land and inclined road side. The weeding implement consists of five main parts; the electronic control system, the hydraulic system, the main frame, the boom and arm mechanism, and the rotary type weeder. And the weeding implement was developed to be attached by three-point hitch of tractor considering the use of electronic control system. As a result, the electronic control test was conducted with the weeding implement attached to tractor in slope land. The results of the electronic control system test showed satisfactory weeding performance.
Development of Walking Assist Smartphone Case for Blind People
Choi, Jin-Woo ; Jeong, Gu-Min ;
The Journal of Korea Institute of Information, Electronics, and Communication Technology, volume 8, issue 3, 2015, Pages 239~242
DOI : 10.17661/jkiiect.2015.8.3.239
In this paper, we propose a walking assisting system for blind people using Android smartphone and Arduino board. In our proposed system, we use an Android smartphone case and an external ultrasonic sensor to detect the obstacles ahead. In this manner, blind people is able to aware unexpected objects by smartphone speakers or vibration functionality. In addition, the walking assisting system is also designed a notice system which will be triggered by built-in smartphone camera flash when blind people walk in some darkness place. The experimental results from real experiments on blind people have demonstrated the applicability of our walking assisting system, when it not only efficiently helps blind people avoid obstacles ahead but also possible traffic collisions in darkness condition.
