The purpose of this study was to analyze the factors that influence middle-aged people's retirement planning and financial preparation for old age. The data was derived from "the National Survey of Families 2015". The samples included 1,462 people from 40 to 64 years of age. The findings from the analysis showed that the level of retirement planning was significantly associated with gender, age, education level, employment status, monthly family income, monthly expenditure on spending to support parents, and perceived household economic condition. When the samples were divided by sex, the results showed that the perceived household economic condition was the most significant factor for both men and women's level of retirement planning. Age and education level were the significant factors for women's level of retirement planning but not for men's. Logistic regression was used to analyze whether middle-aged people made financial preparation for old age. For the whole sample, whether or not a person was a regular employee, monthly family income, monthly expenditure on supporting parents, perceived household economic condition, and retirement planning were significant variables in determining financial preparation. For men, whether or not a person was a regular employee, monthly family income, perceived household economic condition, and retirement planning were significant factors, for women whether or not a person was a regular employee, and retirement planning were the significant factors in determining financial preparation. The results implied that retirement planning is needed for middle-aged people to prepare for old age financially while the financial preparation should differ depending on sex.

The purpose of this study were to investigate the allocation of time for housework and leisure and the causal relations between management satisfaction and all variables affecting it. for this purposes the data were collected through the questionnaire whose respondnet were 448 housewives. The major results of this study were as follows; 1`) The housework time was affected by the number of family member the age of wife and income. And leisure time was affected by the work status and age of wife educational level and income. The satisfaction level of management were affected by the wife's work status and educational level and income. 2) The relation between housework time and time management strategies was negative And the relations between satisfaction level of management and time planning time management strategies were positive. 3) Among all variables affcting the satisfaction level of management the educational level income time planning time management strategies and leisure time had direct effect And the work status had indirect effect.

This research identified approachable management innovation technique from SCM point of view, and analyzed sales/logistics, integrated production planning, phenomenon of cooperation and suggested an innovation model over this for strengthening competitiveness of a case company. Process innovation model with an enterprise viewpoint is designed and suggested to solve the previous ares for improvement, and suggested various models of an ordering management model, available delivery management model, logistics operation model based on planning and S&OP model.

Many 6-sigma innovation companies are obtaining ISO9000 series or ISO/TS16949 certifications. However, not many of them have considered the integrated management of ISO/TS16949 at the time of 6-sigma introduction. ISO/TS16949 focuses on the process of an overall company. In particular, APQP (Advanced Product Quality Planning) requires that from the beginning all the planning should have a clear quality planning business process. Each company can decide the best course of action to suit its individual needs. Lean DFSS in 6-sigma offers the concrete development steps of the product development process. And if analyses of Input, Output, Target, Process, KSF, KPI, and FMEA is done in each process and clearly defined in APQP, mutual organic and effective systems can be initially achieved.

In many people's minds, health promotion is simply a more modern term covering roughly the same field as disease prevention or life style related reduction of the risk factors of chronic disease. A review of the modern literature of health promotion make it clear that there is more to this term than what is involved in functioning as a synonym for disease prevention. Therefore, in order to reach a clear understanding of what health promotion is, this study suggest the concept of the health balance model. Health balance is represented in terms of an equilibrium between physical, social, and life-style-related health challenges on the one hand and health potential on the other hand. Thus, health promotion strategies encompasses both the reduction of health challenges and the strengthening of health potential. Many elements of reducing health challenge are mainly related to the regulation laws. Aspects of strengthening of health potential are related to activities of health center. Therefore, health promotion strategies at a community level should be included in regional health planning which is implemented by health center.

Facility location planning (FLP) problem is the strategic level planning in supply chain. The FLP is significantly affected by the operation time of each facility. In most of the FLP researches, operation time of facility has been treated as a fixed value. However, the operation time is not a static factor in real situations and the fixed operation time may lead unrealistic FLP. In this paper, a mixed integer programming (MIP) model is proposed for solving the 3-stage FLP problem and operation times are adjusted by the results from the simulation model and an iterative approach combining the analytic model and simulation model is proposed to obtain more realistic operation plans for FLP problems.

This paper considers remanufacturing planning problems under deterministic environments. As increasing the environmental pressures in manufacturing, various methods for reducing wasted or postponing the time to be waste are considered. This paper considers remanufacturing planning problems on a single facility, where the wastes(or used products) are remanufactured to satisfy the given demand on the remanufactured products. The objective is to find the optimal remanufacturing and purchasing planning of the wastes which minimize total cost subject to satisfaction all the given demand on the remanufactured products. Two problems that the amount of wastes is a given constant or a decision variable are considered, respectively. For the problems, the extreme point solutions are characterized, and dynamic programming algorithms are developed with numerical examples.

Most of computer-aided process planning(CAPP) systems have been developed to automate the process planning function. In this paper, we describe an analytical model for a CAPP system in order to improve the performance of production system in flexible manufacturing systems(FMSs) for computer intergrated manufacturing(CIM) architecture. This paper proposes an optimal process planning that minimizes the load time by minimizing the cycle time and the number of workstations using Kang and Hahm's heuristic approach so as to improve the performance of production system under the batch production of discrete products. We also perform simulation using SIMAN language to campare the line utilization of each for various product types. The proposed algorithm can be implemented in existing FMSs for on-line control of product quantity using programmable logic controllers(PLC) and communication devices.

In this paper, a two-stage and top-down approach of mid-term and long-term R&D planning of public corporation is proposed to incorporate some characteristics of public corporation and to overcome the complexity of the real world planning. Unlikely to R&D planning of private company, the total investiment size of public corporation is institutionally determined. A top-down approach is developed to adopt this feature. The proposed approach has two stages to overcome the complexity. In the first stage, we develop a plan for R&D area by adopting the business area and the public role of corporation. In the second stage, we develop the detailed plan within each area. The proposed approach is applied to develop the mid-term and long-term R&D plan of Korea Gas Corporation.
