Mass customization utilizes the new computer technologies, supply chain management, product information management, and some level of customization of the product for the individual customer. This study aimed at grasping the actual conditions of mass customization of domestic men's suit industry and the use of MTM CAD program. The MTM apparel production programs that are used by five leading men's suit manufacturers in Korea were compared. The results of the study showed that most of the manufacturers produced mass customized men's suits to supply extraordinarily large or small size suit based on the individual order. The information listed on an order sheet used at shops was not necessarily corresponding to the information in the MTM CAD program that is use for production of suit ordered from the shop. The pattern data base on the MTM CAD program are constructed based on the sizing system of individual manufacturer. The most manufacturers translated the customer's body dimensions into difference between the standard pattern and the customer's needed adjustment.

The purpose of the research is to discuss the product safety procedures for the food area. The producer and supplies of the products should be able to satisfy the needs of the increasing consumer safety. The products, for the purpose of developing and making safe products, must perform Hazard Finding and Risk Analysis to detect potential danger to mike sure the final safety measures are in place. The purpose of Product liability rests finally with the consumer safety and the manufacturer's capability compete in the marketplace. Especially this is important for the food industry. But, our domestic middle and small food industries, it is relatively weak in this are. Thus this research would like to present a easily usable product safety procedures.

The purpose of the research is to discuss the product safety procedures for the food industry The producer and supplier of the products should satisfy the increasing consumer safety needs. To develop and produce safe products, the food industry must rigorously perform potential hazard findings and very thorough risk analysis to detect even the very minute potential danger. The ultimate product liability rests with the consumer safety and the manufacturer's capability which competes in the market places. This is especially important in the food industry. However, small to medium sized food producing companies are facing challenges in this area due to their overall capabilities. Therefore this research presents safety procedures which are relatively simple to implement.

This paper was concerned about case study for preventing WMDSs(Work-related Musculoskeletal Disorders) by using Thinking Process of TOC(Theory Of Constraints), Unfortunately, the number of WMDSs are rising steadily in auto-part manufacturer. These WMDSs have on worse and worse influence not only on the competition of enterprise but on the life quality of a worker. The research results are helpful to establish the preventing WMDSs and improvement of workplace environments for small-medium sized auto-part company.

Based upon a questionnaire survey, this research study focuses on the Japanese apparel manufacturers. The aim is to understand the characteristics that make up the marketing strategys of Japanese small to medium sized apparel manufacturers. The authors generate exploratory hypotheses, which are tested via statistical analysis of data obtained from a questionnaire survey. The hypotheses tested include, the relationships between "High Value Added" strategys and factors involved with manufacturing and marketing channels. High Value Added strategys relate to the manufacturers' competitive behaviors that create high and new value for their products. The results indicate that High Value Added strategys have positive relationships for domestic outsources, the number of outsources, use of directly operated shops and the orientation for sales in overseas markets.

The problem of constrained sequencing of a set of jobs on a conveyor system with the objective of minimizing setup cost is investigated in this paper. A setup cost is associated with extra material, labor, or energy required due to the change of attributes in consecutive jobs at processing stations. A finite set of attributes is considered in this research. Sequencing is constrained by the availability of conveyor junctions. The problem is motivated by the paint purge reduction problem at a major U.S. automotive manufacturer. We first model a diverging junction with a sequence-independent setup cost and predefined attributes as an assignment problem and this model is then extended for a more general situation by relaxing the initial assumptions in various ways.

Recently, more attention has been paid to the development of high-speed permanent magnet (PM) synchronous motors, since they are conductive to high efficiency, high power density, small size, and low weight. In high-speed PM machines, core loss and windage loss form a larger proportion of the total losses than usual in conventional mid- or low speed machines. This article deals with the analysis on the core loss and windage loss in PM synchronous motor for high-speed application. Using the data information from a manufacturer and non-linear curve fitting, this paper investigates the magnetic behavior and its core losses in the stator core using the electrical steels. And, the windage loss is calculated according to the variation of the rotational speed, motor inner pressure and temperature.

Retroreflector is different from other reflecting surfaces as it mades reflection in which radiation is returned in directions close to its incoming direction. Because of this characteristics, retroreflectors find many applications in traffic safety related areas. Retroreflectors are usually made using comer cubes, or partially coated glass beads. These glass beads can be made very small, so that they can be coated on sheets or mixed with paints. The design of glass type retroreflector depends on glass bead's shape and material, and its optical characteristics are related to the refractive index of glass. In this paper, a method of anlyzing glass bead type retroreflector's sptical characteristics with respect to shape and optica property of the glass, is presented. First, the coefficient of retroreflection, which is a measure of retroreflector's optical characteristics, is derived analytically using geometrical optics method. And the result is plotted using numerical methods. The results show good match with those obtained experimentally, which were supplied from a commercial retroreflector manufacturer.

소상공인은 2012년 현재 우리나라 전체 사업체 대비 87.8%를 차지하는 중요한 경제활동의 원동력이다. 그러나 대부분의 소상공인 창업은 소자본으로 창업 및 폐업을 지속적으로 거듭하고 있는 실정에 있으며 소규모 기업은 많은 사람들에게 직접적인 생계수단이기 때문에 우리나라 경제에서 큰 비중을 차지하고 있다. 본 연구에서는 이러한 소상공인들이 소상공인 공동협업체를 위한 제조사별 제품정보 공유기반 협업 서비스 설계하고 유용한 정보를 제공하는 시스템을 보급하고자 한다. 소상공인을 위한 소상공인 공동체 협업화를 위한 시스템을 구축하여 제공함으로써 소상공인들의 경쟁력 강화에 기여할 수 있을 것으로 기대된다.

A grinding technology is very essential to finish the surface of IT and BT industrial application parts such as wafer, optical connection part and lenses etc. However the finding machine has bead depended on imports. Especially, it is completely imported for machining high precision part relevant to domestic electric and communicational industries. The amount to import grinding machine is about $110milions. It takes about 35% of total import amount of all the machine tools. A domestic finder manufacturer is a very small-scaled bussinessman and research facilities is poor. Recently, it is increasing to demand high speed and precision grinding technology because it brings cost down and value added up. Its further study will be something related to inteligent grinding system fur value added and high precision part. It will make domestic grinding technology to its advanced country level.
