This paper is to present design principle and operation strategy of acceptance control chart by the use of OC-Based sampling inspection for continuous data. The unified control limits for acceptance control chart when considering both APL(Acceptable Process Level) and RPL(Rejectable Process Level) are proposed. The control limits can be also extended to the acceptance control chart with unknown process standard deviation.

Measurement is a essential part in all kinds of industry, especially in manufacturing. But until now, measurement hasn't been located to the core of manufacturing in domestic. This study suggests improvement guide line for the multilateral problems of measuring instrument operation based on the investigation of small and medium-sized enterprises. To use measuring instrument correctly, man who treat it must be accustomed with the structure, the performance, the method. The measuring instrument must be corrected periodically. The correcting-schedule is established with environments with considering accuracy, stability, purpose, condition, and frequency.

This article addresses the question of how the operational architecture for a railway safety information system should be developed. A successful railway safety information system can be developed by fully reflecting the business process and needs at the enterprise level. To date, there has been minimal research effort towards the development of the operational architecture for a railway safety information system. To this end, a variety of enterprise architectures have been studied so far. In this paper, as an important guideline, DoDAF (Architecture Framework) is selected to be used in developing a railway safety information system. In particular, we propose a method to implement the operational architecture based on DoDAF.

The purpose of the present study was examine the effects of group contingency management strategy in elementary school physical education setting on the problem of student managerial time for physical education class and to assess three subject teachers t

The purposes of this study were as follows. First is to compare the importance of operational factors to determine types of school breakfast program, and second is to do the preference analysis of operation-related people depending on the attributes and levels of the operation of school breakfast program. The questionnaires developed for this study were distributed to 134 school dietitians, 114 school foodservice officials at the educational board, 68 staff members of foodservice contractors and 493 parents. Statistical data analyses were performed using SPSS/WIN 12.0 for descriptive statistics and conjoint analysis. The conjoint design was applied to evaluate the hypothetical foodservice types. According to the analysis on the attributes and levels of the school breakfast operation, the relative importance of each attribute was as followsprice (36.30%), menu (29.60%), foodservice staff (22.54%), serving type (11.55%) to school dietitians, price (34.99%), menu (28.15%), foodservice staff (23.52%), serving type (13.35%) to school foodservice officials at the educational board, menu (30.55%), price (30.24%), foodservice staff (28.75%), serving type (10.47%) to staff members of foodservice contractors and price (36.34%), menu (29.73%), foodservice staff (21.01%), serving type (12.92%) to parents. The results of the conjoint analysis indicated that the school dietitians and school foodservice officials at the educational board preferred the school breakfast operation program with 3 traditional menus and 2 convenience menus per 5 day, 1~3 foodservice staff, with a price range of 1501~2000won, and tray serving. Staff members of foodservice contractors preferred the school breakfast operation program with 3 traditional menus and 2 convenience menus per 5 day, 1~3 foodservice staff, with a price range of 2501~3000won, and tray serving. Parents preferred the school breakfast operation with 5 traditional menus per 5 day, 6~7 foodservice staff, with a price range of 2501~3000won, and tray serving. About a half of school dietitians considered that elementary schools were appropriate for the suggested school breakfast operation program. But, 68.2% of school foodservice officials at the educational board, 69.1% of staff members of foodservice contractors, and 38.1% of parents considered high schools to be the suitable model. Therefore, it indicated the need to recognize the different opinions among breakfast operation-related people and take these factors into consideration in developing the school breakfast program.

Intelligent machines respond to external environments on the basis of decisions that are made by sensing the changes in the environment and analyzing the obtained information. This study focuses on the construction of a knowledge base which enables decision making with that information. Approximately 70% of all errors that occur in machine tools are caused by thermal error. In order to proactive deal with these errors, a system which measures the temperature of each part and predicts and compensates the displacement of each axis has been developed. The system was built in an open type controller to enable machine tools to measure temperature changes and compensate the displacement. The construction of a machining knowledge base is important for the implementation of intelligent machine tools, and is expected to be applicable to the network based intelligent machine tools which look set to appear sooner or later.

All of the city gas companies in Korea must employ the gas safety patrols by law. The gas safety patrols are responsible for the various tasks including daily gas pipeline patrol to prevent gas accidents. Since the size of jurisdiction varies among the city gas companies, it is very difficult to compare their efficiency for the operations of the safety patrol each other directly. The objective of this research is to develop the methodology to analyze and compare the efficiency of the safety patrol's operations among various city gas companies. Several factors that are related to the safety patrol's duty on the gas safety factors were identified and DEA(Data Envelopment Analysis) model for efficiency analysis was developed. Finally, the DEA model was applied to the collected data from six city gas companies. The less efficient city gas companies can benchmark the higher efficient city gas companies in order to improve the safety control systems.

본 연구는 우리나라 RCC/RSC의 효율성을 2개의 입력변수와 5개의 출력변수로 한 토대로 퍼지 DEA를 이용하여 측정 평가하였다. 특히, 본 연구에서는 해양사고 발생자료 뿐만 아니라 환경스트레스치에 의한 잠재적 해양사고 발생가능 자료도 고려하여 운영효율성을 분석하였다. 한편, 현실자료에는 수많은 애매성이 존재하기 때문에 본 연구에서는 DEA법에 퍼지이론을 이용한 퍼지 DEA법을 이용하였다. 이 퍼지DEA법은 α-cut을 기반으로 한 크리습 선형계획문제로 변환된 것으로 입/출력 변수를 삼각형 퍼지수로 하여 해를 산출하는 방법을 제안하였고, 제안된 퍼지 DEA를 이용하여 퍼지 RCC/RSC의 순위를 결정하였다. α-cut을 0.5로 하여 효율성을 산출한 결과 YS, BS, MP, TY, JJ, PH, US, IC, SC, DH, GS, TA, WD RCC/RSC 순으로 효율성이 높게 나타났다. 따라서 효율성이 비교적 낮게 평가된 TA, WD RCC/RSC는 효율성이 높은 준거집단을 참조하여 벤치마킹을 해야 할 필요가 있다.

본 연구에서는 국내 해운회사의 안전관리를 위한 여러 가지 투입요소와 산출요소들에 대한 자료를 설문조사하고, 각 해운회사간의 안전관리체제 이행에 따른 효율성을 DEA 분석법을 사용하여 분석하였다. 1998년~2004년까지 각 해운회사의 안전관리체체의 운영효율성을 DEA 모형으로 분석한 결과, 효율성 평균지수가 매년 감소하는 추세를 나타내었다. 효율성 평균지수가 매년 낮아지는 경향을 보이는 이유는 해양사고 건수, PSC지적 건수, 선박보험료, P&I 보험료는 매 년 감소하는 것에 비해 선박수리비, 선용품비와 선박 불가동일수는 매년 감소하지 않고 오히려 증가하는 경향을 보이고 있는 것이 주요한 원인으로 분석되었다.

Nowadays, globally high-grade companies have done their best for increasing their competitive power through a many kinds of method in incisive competition for making certain of a pacesetting position. Among the rest, Six Sigma have been the best methodology of improving process and have proven to be effective by the result of improving process in many of manufacturing business, however, it has not obtained excellent results in the transaction business. In transaction business, a 30~50% costs in total costs is generated by slow-speed working and reworking. The slow processes decrease the quality and increase the cost, which decreases customer satisfaction, and finally the income is decreased. All of them are so called wastes in processes. For this, adopting of lean six sigma methodology in process management can eliminate the wastes and reduce the variation. This study focuses on distribution with the domains like capacity, layout, amount of location, assignment of product, operation procedure and operation rule in order to improve these domains, we make a further application of eight analysis ways based on DMAIC method for improving operation of processes of distribution center as the third profit source. The goal of this study is to trace an approach that can easily adopt of Lean Six Sigma in operational management of distribution center by a kind of data, analysis method and template.

Traditionally the availability of probation should be an alternative to incarceration, its innovation is more widely spread in the world. The founder of the probation, Boston's John Augustus, was concernd about drunks being put in jail to dry out. He felt they needed help, so he took them into his home as an compassionate act. Since his successful supervision and recommanding reformation of corrections, probation has become the most commonly alternative in America and other countries. The presentence investigation report considered by probation officer and state statutes help guide the court in determining whether an offender is a suitable candidate for probation. Of course to those convicted of murder, sex crimes, other serious assaults and those with a serious criminal record, probation must not be granted. Perhaps probation is most commonly granted to first-time offenders, property offenders, low-risk offenders, non violent offenders and probation involves minimal levels of supervision and restriction. Model probation should purpose to help low-risk offenders maintain law-abiding behaviour, Sometimes some courts emphasize treatment oriented conditions, others more punitive conditions. One common condition for all probationers is to obey the law. Other conditions are, for example, cooperating with a program of supervision, meeting family responsibilities, maintaining steady employment or engaging or refraining from engaging in a specific employment or occupation, pursuing prescribed educational or vocational training, maintaining residence in a prescribed area or in a special facility established for or available to persons on probation, refraining from consorting with certain types of people or frequenting certain types of places etc. To attain successful probation, many officers' caseloads should not be so massive, people who receive standard probation should undergo periodic or random testing for probability of future crime or future delinquent behaviour. Probation is one of the correctional options, whose goal is to control crimes and delinquent behaviour. To achieve this goal depends almost all upon mitigating the heavy caseloads of most probation officers and furthering the ability of probation officers to closely monitor and supervise those probationers.

The Certification system will be able to expect that effect of marketing and the corporate image rising, if the certification body guarantees the contents of certification against industrial technical advance and safety, environment and efficiency, quality when it is suitable in the standard which is provided. The certificationsystem where the private organization operates but recently on the legal notarization outside is disordering and the trust regarding the certificationfalls and the objective and gist of origin are damaged. But recently the trust of certification has fallen and the objective and gist of origin are damaged. Because the non-government certifications are disordering. Also the damage of the consumers majority occurs but it is insufficient the investigation analysis against the present condition regarding a non-government certification system and the operation actual condition. So it is necessary the actual condition where the countermeasure against hereupon is urgent. In this study, we present the operation direction of efficient against non-government certification system through investigation and the analysis.
