A rectifying inspection plan is considered for the case of destructive testing. Screening inspection for rejected lots is performed by some nondestructive testing which is prone to misclassification errors. Apparent defectives found in the screening process is replaced with apparent good items. The plan provides LTPD protection on each individual lot while the sum of the cost of testing and the cost due to producer's risk at process average quality is minimized. A brief discussion on average outgoing quality is also given.

본 연구에서는 지적측량수수료 종목들에 대한 산정 공정의 지적측량업무 전산환경 반영 정도를 분석해 이에 대한 문제점들을 도출하고, 현 지적측량업무 환경에 부합할 수 있는 공정의 개선방안을 제시하고자 하였다. 문제점 분석결과, 현재 지적측량수수료 공정은 관련 측량 수수료 산정공정과 비교할 경우 복잡성이 있는 것으로 분석되었다. 그리고 현행지적측량기술의 환경 변화나 디지털 지적관리 체계 전환에 따라 업무별 작업 공정이 개선되었음에도 불구하고 부분적으로 이를 반영하지 못하고 있는 것으로 나타났다. 이에 대한 개선방안에 대해 연구에서는 현재의 보편적인 9단계의 공정을 4단계의 공정으로 개선하는 단순화 방안을 제시하였다. 그리고 현지측량 전 후에 있어 전산파일에 의한 개선된 작업 공정이 적용될 수 있는 개선안을 제시하였다. 끝으로 전산환경에 적합하도록 도면작성 관련 업무의 공정을 4단계로 구분하고, 이에 부합하는 공정의 개선하는 방안을 제시하였다.

This paper presents another system of multi-level skip-lot sampling plan, which can directly retum to normal inspection from any skpping inspection level when a sudden shift for the worse in the process mean occurs. All the other properties of the proposed sampling plan are similar to those of the Choi's(1993) plan. The formula of the poerating characteristic function for the proposed n-level skip-lot sampling plan is derived. Sone poerating characteristic properties for the proposed plan are graphically compared with those of the Choi's plan.

Objectives: This study aims to recognize the importance of dental hygiene process diagnosis of dental hygiene process which can comprehensively grasp the patient's problem and to use it as a basis for establishing the patient's preventive treatment plan. Methods: This study did survey to 443 patients who received treatment based on the oral health care program from a dental clinic in Busan from January 2015 to January 2017. Data analysis was performed using IBM SPSS Statistics (Version 21.0), and statistical significance level was set at ${\alpha}=0.05$. Binary logistic regression analysis was performed to the dental hygiene problems affecting the dental hygiene plan. Results: There were significant differences in dental hygiene problems between male and female respondents on various dental problems such as dental plaque deposition, attrition, stain, dental fear, possibility of jaw joint disorder, food pressing, possibility of malocclusion. There were also significant differences in dental hygiene plans between male and female respondents in air-Jet, non-smoking education, and sealant. The most common dental hygiene plan was scaling, The problem of stain showed that the scaling plan was 0.20 times less. The explanatory power of the model was 43.5%, and the Hosmer and Lemeshow tests were 0.345. Conclusions: Therefore, if we continue to study the factors affecting the dental hygiene problems and the plan, we can reduce the burden of the dental hygienists applying the dental hygiene process in the dental clinic. And, it is expected that the oral health care program using the dental hygiene process will spread to the dental clinic as an excellent oral preventive program.

In Korea, asbestos removal has been actively carried out nationwide since 2015 when asbestos was completely banned as a first-class carcinogen. Since scattering dust generated in the process of removing asbestos causes fatal diseases such as asbestos lung disease and lung cancer, concerns are growing over the safety of construction workers and building users undergoing dismantling. For this reason, regulations on asbestos sites have been strengthened and prior studies on safety and risk assessment have been conducted, but research on actual site data collection and process planning is insufficient even though safety is reduced due to delay in site construction period. Therefore, it is necessary to analyze the work and delay factors of the asbestos dismantling process and develop an optimized process plan model for workers. This study is an initial step to develop an optimized process plan model that considers the safety and productivity of asbestos dismantling work, and aims to help establish an optimized process plan for asbestos dismantling process using website clone simulation.

Today's competitive global market makes most enterprise endeavor to specialize their business areas, and co-operate with trading partners in supply chain by the forms of collaboration, information and business process sharing. However, even the supply chain plan generated by co-operation often fails to be executed successfully, because it was generated without capacities of suppliers and more over nested suppliers. To overcome this limitation, the supply chain plan of an enterprise should be generated truly integrated way. In this paper, we classify business patterns based on scenarios about quotation processing and supply chain planning in self-integrated environment. And we present business process models about four business patterns and describe them, which are classified by whether request for quotation includes information about price, required time periods, and quantity for each required time period and whether it is received from customer or sent to supplier. In addition, we describe the types of supply chain planning problem.

In stamping-die manufacturing, the first step is to build die patterns for lost wax casting process. A recent industry trend is to manufacture the die pattern using 3-axis NC machining. This study identifies technical considerations of the pattern machining caused by the characteristics of Styrofoam material, and proposes technical methods related to establishing a process plan and generating tool paths for optimizing the pattern machining. In this paper, the process plan includes the fellowing three items: 1) deter-mining a global machining sequence-a sequence of profile, top, bottom machining and two set-ups, 2) extracting machining features from a pattern model and merging them, and 3) determining a machining sequence of machining features. To each machining feature, this study determines the machining start point, generates the approach tool path, and proposes a tool path linking method fur reducing the distance of the cutter rapid motion. Finally, a smooth tool path generation and an automatic feedrate adjustment (AFA) method are introduced far raising the machining efficiency.

The purpose of this study is to provide information needed to the construction of the co-housing in the urban area. This study focused on the characteristics of co-housing in its planning process of private house & common space; 'economy', 'creativity' & 'sociality'. The object of this study is co-housing in 'Seongmi-san Village' in Seoul, which was built by a coordination company with residents' participation. The methods are investigating interview materials, floor plans of 9 households, & common space plans produced in the coordination process from the basic plan of private house & common space to the final plan. The results are as follows. 1) The size and plan of private house differed from each other. The water pipe location differed from each floor, so that there were difficulties in construction. In conclusion, these made no 'economy', but brought high 'creativity'. 2) The 'sociality' would be estimated as high because there were various types of resident participation; resident interviews on the planning, workshops for private housing plan, and workshops for common space.
