In start up process control, it may be necessary to use appropriate scheme in monitoring processes with individual observations. In these situation individual observations are periodically drawn from the process. In this paper, using modifying statistics with individual measurement, we suggest a simple technique which operating control chart for monitoring the process. And compare individual observation control procedures that are X, an exponentially weighted moving(EWM), adjusted EWM and adjusted MCEWM charts. And estimate the ARL to detection of shifts in the process mean and standard deviation using simulation.

컴퓨터와 네트워크 기술이 발전하면서 물리적으로 분산되어 있던 시설들이 논리적으로 통합 관리되고 있다. 이 시대에 맞춰 국방부 또한 "국방정보화" 라는 단어를 통해 국방체계를 IT 중심의 군 체계로 전환하고 있는 가운데 네트워크 전체를 마비시키는 사이버 위협은 날이 갈수록 늘어나는 상황이며 사이버 안보에 있어 외부로부터의 침입을 막고 내부로부터의 유출을 막기 위한 실시간 보안관리는 점점 더 중요해지고 있는 상황이다. 또한 군사기반시설에 대한 관리적 및 기술적 환경측면에서 발생할 수 있는 보안 사고에 대응하기 위하여 실시간 보안관리 체계는 수립단계부터 세부적인 평가가 반드시 수행되어야 한다. 이에 본 논문은 국외 관리체계 및 국내기업 우수사례 분석을 통해 보호체계 수립단계에서 세부적인 평가단계까지 실질적으로 보안에서 중요시하는 관리적, 기술적, 개인정보에 근거한 실시간 보안관리 체계를 통하여 군에 효과적으로 적용할 수 있는 국방망의 지속적인 실시간 보안관리 체계를 제안한다.

We investigated the question whether the efficacy of cleaning tear components on RGP lens and preserving the superior wettability of RGP lens depended on the different type of contact lens care system - RGP lens care solution, SCL care solution, combined solution both for SCL and RGP lens or saline solution. The removal efficacy of the deposited protein was examined by Lowry protein assay and Scanning Electro Microscope(SEM) and residual lipid concentration on RGP lens was determined by High Pressure Liquid Chromatology(HPLC). Wettability was assessed with an equilibrium water-in-air contact angle method. When cared by RGP lens solution, it was demonstrated that 62 percent out of the adhered protein on RGP lens were removed and the removal efficacy of RGP lens solution was not only 4 times than saline solution and the alternative but also higher twice than SCL solution. Contrarily, the SCL solution had the most excellent removal efficacy of the adhered protein on SCL. These results suggest that the cleaning efficacy is thought to be affected by the other factors like the viscosity of care solutions, which mutual contact between RGP lens and care solutions is on the increase due to the viscosity enhancer in RGP lens care solution. RGP lens solution had the greatest removing efficacy to cholesterol and the residual cholesterol concentration was decreased to 50%. It is significant for RGP lens to preserve the superior wettability which means the predictive value for comfortable wearing and it showed that the RGP lens solution offered the most excellent efficacy to maintain the surface wettability. Combined solution both for SCL and RGP lens had weak efficacy of cleaning and maintaining wettability for RGP lens compared to RGP lens care solution.

It is important to control performance and a Sustainable Collaboration (SC) for the successful Supply Chain Management (SCM). This research developed a control model which analyzed SCM performances based on a Balanced Scorecard (ESC) and an SC using Support Vector Machine (SVM). 108 specialists of an SCM completed the questionnaires. We analyzed experimental data set using SVM. This research compared the forecasting accuracy of an SCMSC through four types of SVM kernels: (1) linear, (2) polynomial (3) Radial Basis Function (REF), and (4) sigmoid kernel (linear > RBF > Sigmoid > Polynomial). Then, this study compares the prediction performance of SVM linear kernel with Artificial Neural Network. (ANN). The research findings show that using SVM linear kernel to forecast an SCMSC is the most outstanding. Thus SVM linear kernel provides a promising alternative to an SC control level. A company which pursues an SCM can use the information of an SC in the SVM model.

The competition between ship management companies is fierce as a result of global trend towards increased specialization. In order for ship management companies to remain competitive, it is necessary to understand the local and global factors and the changing circumstances that impact shipping markets and trade patterns. To better understand these factors, a study and analysis of drawing priority of the competitiveness-evaluation factors of ship management companies was conducted using Analytical Hierarchy Process(AHP) as a method dealing with dicision-making problem. As a consequence of this analysis, it was determined that human resources, both shipboard and land management, were a primary factor in ship management company's competitiveness. Thus, the acquisition and retention of capable staff was a key aspect of assuring a ship management company's competitiveness.

Recently, import liberalization begin in earnest through the WTO/FTA. but the interior agriculture status is insufficient to management system. So, interior agriculture will hard hit before import liberalization. Whereupon, the government organs establish GAP standard that elevate a quality of agricultural product. And be in force preferential application to valuable agricultural product like ginseng. In this paper, we designed of management system for culture and distributive of ginseng that correspond of interior GAP standard. And we implementation of system for offered to information of recording data. Also, we recorded of data that weather, insect, agrochemical and manure for studing of good product. And we introduced monitoring system and guidance as well as management system for efficient system management.

LoRa LPWAN network system uses a license-exempt wireless communication system and implements data measurement through the integrated sensor based on Mems and wireless communication of existing measurement sensors. This system has superior technological / economic superiority using existing network and long distance communication compared to existing wireless measurement system, and secured economical efficiency by minimizing system construction equipment compared to wired measurement system. It is confirmed that the economical efficiency can be reduced by 41% compared to the conventional wired metering system. Since the LoRa LPWAN network system is excellent in terms of maintenance and operation, if installed in many bridges in Korea in the future, it will be developed as an excellent system in the maintenance of bridges. Etc.), and plant field (fire safety, etc.).
