An Allium-odorum is difficult material to handle because it is soft and weak mechanically. For bundling work of allium-odorum, we must grip in the bundle shape of unit weight. However it is difficult to grip allium-odorum by hand because the bundle bulk is very big. Especially, in packing work, the bundle shape of allium-odorum package is more important than other vegetables because the sale price depend on the bundle shape. In this paper, we propose bundling mechanism for a rectangular shape, and semi-auto bundling mechanism by a eccentric roller and a triangular link. We carry out mechanical model and analysis respectively using the CATIA V5 and SimDesigner. We have manufactured the prototype of the semi-automatic bundling machine, and got satisfied result through field test. This machine is in the process of commercialization.

To examine the opinions of consumers concerning the ricecake as a traditional food, we conducted the study of the cognition and interests of children and mothers ricecake for its popularization. Our subjects of study were elementary school children as the future consumers and their mothers as the present consumers. The results were as follows: children favored to eat much more western style food and sweet food than did mothers. All of children and mothers liked traditional food and ricecake, but children did not know how to prepare the traditional food and ricecake, indicating thenecessity of the education of ricecake-making. All of them were satisfied with the taste of ricecake 'on sale, but not with packaging designs and price of ricecake. Development of packaging designs was required for popularization of ricecake to spread worldwide.

The most important task in Korean dairy industry is to keep the seasonal and annual balance of raw milk supply and demand. Too much surplus milk supply which causes dumping sale of market milk makes dairy industries get in trouble of management, and eventually affects to farmers and consumers economically. As balancing of supply and demand is so important in the fee economic market system, the adaption of the quota system of milk production and seasonal price differentiation has been recommended very often as a method of controlling the milk supply and demand. However, this recommendation did not go through successfully due to the strong objection of dairy farmers. Recently, the voice of consumer's requirement for safer and more hygienic, and high protein, low fat level dairy product is getting stronger. By knowledge of this kind changes, quality improvement in nutrients and hygiene is the most positive way to expand the volume of milk consumption. To meet the consumer's demand, therefore, it is necessary to revise the level of milk fat content and the hygienic grading system for the payment system of raw milk.

The first introduction of reformed Korean traditional cloth in was started in the age of civilization and until liberation from imperialism it was made a reformation in faculty from Korean traditional clothing. And by 1980s western style costume took lead but after Asian Game in 1986 and Seoul Olympic in 1988 Korean traditional beauty was added to costume and there were various attempt to produce truly reformed Korean traditional clothing. The present condition of reformed Korean traditional clothing in 1990s are like this : 1) Most of reformed Korean traditional clothing ships could not fractionalize customers. So it needs to subdivide and specialize customer and investment to improvement of design. 2) A large percentage of reformed Korean traditional clothing is ordinary dresses. So it should develop various sorts and color, design and textile and be in harmony with international trend. 3) Most of shops handled a coordinate goods like a bag and shoes. 4) In the investigation customers they wanted various colors, high quality in design , logical price and a periodical sale. So four pieces of the reformed Korean traditional costumes were designed and produced based on the present condition.

As one of ancillary services, voltage support and reactive power service should be compensed properly for its contribution. In this paper, a cost-based reactive power planning is presented. which minimizes the total cost of reactive power support of generators and VAR compensation facility installation. Reactive power support of generator is evaluated by the opportunity costs of reduced energy sale considering the varying SMP(system marginal price) in power market, Gradient projection method is applied to solve this reactive power planning using IEEE14 bus system.

Customer satisfaction level is usually measured in terms of price, qualify, customization, after-sale-service, product variety etc. Each firm sets up a distinctive production/marketing strategy to gain competitive advantage by Prioritizing the customer satisfaction measures. The market differentiation strategy directly results in supply chain performance such as lead time, inventory, customer fill rate and market share. Product proliferation desirable in customization sense often conflicts the economies of scale effect in production side. This paper focuses the relationship between product variety and market share. Specifically, we investigate how introduction of new product affects the current market share, i.e., formation of customer preference and provide some insight into the optimal range of product variety.

Under the changed market condition, The objectives of this study are to develop and test a research model specifying the relationship between customer loyalty and sale of environment-friendly food in korea. The target population of this research is consumers in seoul and some major cities. they are judged to have bigger environment-friendly food buying power and represent the future environment-friendly food consumption trend in korea. Results acquired from statistical analysis can be summarized like the following. The label-related components were important factors effecting the satisfaction and the loyalty. Also this study indicate that the customer loyalty is positively related to producer, ingredient indication, advertisement, and negatively related to price.

This study investigated the management environment of medium and small business by examining the role of medium and small business in national economics, the change in management condition, and the problems in quality and technique. Also we analyzed problems in the past quality control activity of our medium and small business, and examined the driving direction and intorduction method of QM. And to understand the effect of manager's concern in quality management to observe the quality system before and after introduction of QM. A target for this investigation is the medium and small business which has introduced QM through ISO 9000. Also analyzed how 05 observance effects to the sale price, process effect customer complaint and on-time delibery by an oral test.

The calculation of each unit cost of productions is very important for evaluating the economical efficiency and deciding the reasonable sale price. In the present, two methods of exergy costing on multiple energy systems are suggested to reduce the complexities of conventional SPECO method and MOPSA method and to improve the calculation efficiency of exergoeconomics. The suggested methods were applied to a gas-turbine cogeneration and the unit costs of the power and the steam energy were calculated as an example. The main points of our methods are the following three. First, one exergetic cost is applied to one cycle or system. Second, the suggested equations are the internal cost balance equation and the production cost balance equation. Third, necessary states in a system are only inlet and exit states of 1ha components producing energy.

This study explores the variables that predict the job satisfaction of clothing salespeople. A total of 270 questionnaires obtained from clothing salespeople were submitted for analysis. The results show that job stress was a negative influence whereas customer-orientation and self-efficacy were positive influences on the job satisfaction of clothing salespeople. The relationships were repeatedly investigated by the groups divided by personal and store characteristics. Job stress was not different by job experience, job position, and the price level of the products for sale; however, customer orientation, self-efficacy, and job satisfaction were different by those factors. In the case of more experienced salespeople with high positions, job stress would not be a predictor of job satisfaction. The study findings confirmed variables predicting job satisfaction, as well as revealed some personal and store characteristics that can affect the relationships of the variables.
