South Korea has allowed parallel importation since 1995. Parallel importation causes competition among importers in the logistics process allowing, consumers to purchase foreign brand products at low prices. Most parallel importers base product pricing on subjective judgements. Fashion products in particular, have different sales rates depending on trends and seasons, so sales performance varies greatly depending on selling price timing and policy. The merchandiser (MD) set the price on parallel importation products by aggregating information on imported products and pricing goods. However, this customized process is very time consuming for the MD. This is because the logistics process of parallel importation's customs clearance procedures and repair works is complicated and takes a significant amount of time. In this paper, we propose an improved parallel importation logistics process based on big data, which automatically sets the price of parallel importation products.

This paper considers the problem of determining the optimal process mean and screening specification limits of a surrogate variable associated with product quality under two-stage screening procedure. In two-stage screening, the surrogate variable is inspected first to decide whether an item should be accepted, rejected or additional observations should be taken. If additional observations are required, the performance variable of interest is then observed to classify the undecided items. Assuming that the performance variable and the surrogate variable are jointly normally distributed, the optimal process mean and the screening limits are obtained by maximizing the expected profit which includes selling price, production, reprocessing, inspection and penalty costs. A numerical example is presented and numerical studies are performed to compare the proposed two-stage screening procedure with single-stage screening procedures.

Although the technology of breadmaking simply goes through the process of mixing, fermentation, and baking, it is very hard to make a same product every day. The reason is that baking science begins with the very first process of breadmaking which is mixing, and every steps and working environments are so closely connected. The baking science has developed in short time since the theory of fermentation has released. If you check the development of baking technology synthetically, it is consisted of the discovery of nutritional and functional ingredients, the optimization process of new machines, and the maintenance of the quality as fulfilling social demands. Because the baking business is making and selling the product, baking itself is a business, and it has the form that manufacturing and service business coexist. In today's current domestic bakery market, the supply exceeds the demand. Moreover, the concept of bakery itself has been changing from the fixed image of bakery which is selling the bread to the differentiated bakery with others. As we look at the general bakery's trends, it is focused on going back to the basic or traditions, going to the functional, and working with automations. To conclude, the baking has a long history, but it actually has the short history in the technological development. Baking business can be viewed as the simple business, but many factors are related to the business. It has a few basic kinds of products in baking, but it has diverse kinds of products with the base of infinite creativity. Even though it is physically a hard working business, it is also a business that can face with fun. For managing a bakery, finally, the differentiated strategy with other bakery that maximizes the customers' value is needed.

In recent, a great number of electric motor units (EMUs) have been disused in Korea according as its legal duration is 25 years. Generally, the disused EMUs are disposed by selling original form or scrapping for junk. Until now, any efficient disposal system for disused EMUs has not existed. The purpose of this study was to develop the recycling process for the FRP used as an interior panel of EMU. This process was to manufacture a product mixing binders, fillers and the powdered FRP. The characteristics of a product were changed with the mixing ratio of the powdered FRP. The optimal ratio of the powdered FRP was from 10 % to 15 % (w/w). In the future, the application of this process can enhance the efficiency of resource recycling and decrease the cost of waste treatment in the EMU industry.

In case of high-tech process industries such as semiconductor and TFT-LCD manufactures, fault of a virtually finished product that is value-added one, since it has gone throughout the most of processes, may give rise to quality cost nearly amount to its selling price and can be a main cause that decreases the efficiency of manufacturing process. This paper proposes a real-time dispatching algorithm for semiconductor manufacturing process with rework. In order to evaluate the proposed algorithm, this paper examines the performance of the proposed method by comparing it with that of the existing dispatching algorithms, based on various experimental data.

Since the global financial crisis, funding for startups or ventures has been diminished seriously. In this situation, crowd-funding has attracted worldwide attention as a viable means to financing startups/ventures. After reviewing existing laws in other countries, this study investigated the current status of crowd-funding legalization in Korea and surveyed requirements from three groups of participants to crowd-funding. Investors already recognized the high risk of crowd-funding into startups and asked for the protection of their investment. But, their priorities were on the enlargement of tax benefits and the establishment of a trading market for selling their equity. In addition, investors wanted to shorten the compulsory holding period. Issuers as fund raisers hoped fast legalization, convenient process of crowd-funding, and expansion of government support. Crowd-funding platform operators requested policies for establishing paths to become new growth companies from startups, tax benefits, and the setup of separate fund for startups. Currently, the National Assembly in Korea is holding the discussion on the submitted law. For desirable outcomes to all participants, it would be better to proceed in the following sequence. First, legalize the crowd-funding with clauses protecting investors; Second, encourage investment through tax benefits; Third, develop communities among participants for reducing information asymmetry; And fourth, establish diverse trading markets for selling equities of startups.

The purpose of this study is to examine the local farmers' perceptions toward the use of local food for school meals from the suppliers' perspectives. Data was collected from 12 school-meal management centers which provide the name list of local farmers. from the provided list, 167 people were selected, who were asked to answer the self-administerd questionnaires by post. 87 responses were returned, having shown the response rate was 50.1%. The data were analyzed by using SPSS 15.0 for descriptive analysis. The findings from this study are as follows: First, the local farmers has a positive attitude toward certified and supply methods for local food whereas price and selling quantity of local food were dissatisfying; Second, local farmers prefer to use public supplying chains such as school-meal support centers rather than private ones. Furthermore, they like to directly contact with a school in terms of supplying local food. To establish self-selling systems, computer programs like ERP should be adopted to effectively manage the production process of local food. On conclusion, implications and limitations were discussed.

This paper considers the problem of determining the optimum proccss mean value of the quality characteristic of interest, and the screening limit for two correlated variables under single-stage screening. In the single-stage screening, inspection is performed on two correlated variables which are correlated with the quality characteristic of interest. Model is constructed which involves selling price, production, inspection, and penalty costs. Method for finding the optimum process mean and screening limit are presented when the quality characteristic of interest and the correlated variables are assumed to be jointly normally distributed. A numerical example is presented and numerical analysis is performed to compare the proposed screening based on two screening variables with screening based on one screening variable.

This paper is concerned with an economic selection of both the process mean and the lower limit for a continuous production process with the quadratic loss function. It is assumed that the quality characteristic is normally distributed with a known variability. A profit model is developed which involves selling price, production cost, reprocessing cost and the cost which is incurred by imperfect quality. Methods of finding optimum values of the process mean and the lower limit are presented, and a numerical example is given.
