Consider a canning process where cans are filled with an expensive ingredient. Cans weighting above the specified limit are sold in a regular market for a fixed price, and underfilled cans are emptied and refilled at the expense of a reprocessing cost. In this paper, the effect of measurement error on the determination of the optimal process mean for a canning process is examined. It is assumed that the quantity X of ingredient in a can is normally distributed with unknown mean and known variance, and the observed value Y of X is also normally distributed with known mean and variance. A profit model is constructed which involves selling price. cost of ingredients, reprocessing cost. and cost from an accepted nonconforming can, and methods of finding the optimal process mean and the cutoff value on Y are presented. It is shown that the optimal process mean increases. and the expected profit decreases when the measurement error is relatively large in comparison to the process variance.

The purpose of this research is to identify what factors influence a customer's purchasing intention and to identify if customer's attitudes are different between an Internet shopping mall in Singapore and Korea. To perform a cross-nation analysis between Singapore and Korea, this research reapplied the finding of Liao and Cheung(2001) in a Singapore Internet shopping mall, including transactions security, Internet usage, price, shopping experience, vendor quality, network speed. The empirical results of this research indicate that all hypotheses in our model are significant; therefore, Internet usage, price, vendor quality and network speed influence customer's purchasing intention positively and transactions security and shopping experience negatively. The results of a cross-nation analysis indicate that customer's attitudes in both Singapore and Korea are the same. Therefore, Asia's with similar cultures are the same factors In Internet shopping mall. In Conclusion, with the rapid growth of the Internet market in Asia, many cross-nations researches based on Asia culture must be published.

This paper investigates the extent of global and regional integration in East Asia using stock price index as a measure of economic performance. We employ a structural VAR model to separate the underlying shocks into "global", "regional" and "country-specific" shocks. The estimation results show that country-specific shocks still play a dominant role in East Asia although their role appears to have declined over time, especially after the 1997 financial crisis. Global and regional shocks are responsible for small but increasing shares of stock price fluctuations in all countries. The results indicate that the stock markets in East Asia remain dissimilar and are subject to asymmetric shocks in comparison to European countries.

The main purposes of this article are to introduce the theoretical backgrounds and empirical application methods of two different Models for the function of expenditure, and to compare the goodness-o(-fit of the two models: a single-equation model and a complete-system-of-demand-equation model. For the empirical analysis of the single-equation model, a linear formula and a double-leg formula were employed. In order to test the complete-system-of-demand-equation model empirically, the \"Linear Approximation/Almost Ideal Demand System (LA/AIDS)" was used. The independent variables were the total living expense and expenditure categories Price index. The data used in this study were obtained from the quarterly statistics of "The Annual Report on the Urban Family Income and Expenditure Survey (Dosigagyeyonbo)" and "The Annual Report on the Consumer Price Index (Sobijamulgajaryo)," for the years 1994 to 1997. The goodness-of-fit (R-square) was higher with the complete-system-of-demand-equation model than with the single-equation model for the budget share on food (excluding eating-out expenses) and for the share on cultural and recreational activities. However, there was no difference between the two models in terms of the proportion of the expenditure on automobile fuel.fuel.

Recently the Korean government announced its decision to select the $3^{rd}$ proposal, which targets reducing $CO_2$ by 37% of the BAU level by 2030, for the Intended Nationally Determined Contribution (INDC). According to this proposal, natural gas (or equivalent gas) combined cycle (NGCC) are suggested as alternatives for conventional pulverized coal (PC). In this study, we analyzed the environmental, economic, and energy mixing aspects of synthetic natural gas combined cycle(SNGCC) using NETL material (2011~2012 version) and other domestic materials (2014 version). We found the following conclusions: 1) Considering carbon capture and storage (CCS) integration, $CO_2$ emission factors of SNGCC and supercritical PC are the same. However, 60% of $CO_2$ from SNGCC is produced as high pressure and high purity (99%) gas, making it highly suitable for CCS, which is now strongly supported by the government. 2) Based on the economic analysis for SNGCC using domestic materials and comparison with NGCC, it was found that the settlement price of SNGCC was 30% lower than that of NGCC.

Thesedays, not only a quality of a product but also a design of it plays an important role. Throughout this analysis, I would like to discuss how a design of package works in the cosmetics with the fact that low cost cosmetics sales better than high cost cosmetics. In this research, there are five samples each for Korean and Chinese low-costed cosmetics to yield a result about an element of package design. Based on that result, there was an survey about two different package design followed by the research problems. Throughout research, an attention and familiarity of package which was considered of characteristics of China was more effective on Chinese consumers. In order to activate the content market of cosmetics, it is utilized to manufacture taking into account the maximum of the design elements in the package design is a conclusion that affect the time of purchase. In this paper, one in which I hope to help in the development of being utilized as a basis article content market industry for pre-market research foray into the Chinese market is South Korean cosmetics.

본 논문은 농수축산물 및 도·소매 시장 자료를 통해 데이터베이스를 구축하여 시장별 상품의 가격, 장소, 기간 등의 정보를 일자별로 제공하는 시스템이다. 농수축산물의 경우, 크기, 신선도, 보관기간 등의 다양한 기준에 따라 가격이 형성되는데 상품 특성상 기상 변화와 계절 변화에 따른 생산량 및 상품의 질 차이가 매우 크기 때문에 상품의 공급량과 가격의 안정성을 보장하기 힘들다. 기존의 농수축산물 가격 제공 사례의 경우 정보 제공 범위가 좁아 정보의 유용성에 한계점이 존재하였다. 이를 보완하여 시장 위치와 제품 정보의 구체성 확보, 실시간 가격 정보 제공으로 정보의 폭을 넓혀 경제 주체에게 실질적으로 도움을 주고자 하였다. 이를 통해, 소비자들은 원하는 상품의 정보를 제공받아 가격, 거리, 품질 등의 주관적인 기준에 근거한 합리적 소비를 할 수 있다.

In this paper, the system is proposed and implemented to share the part number, the part name, and the vehicle type through the improvement sharing bulletin board for automobile repair and maintenance. And when photos of damage parts are uploaded to the system, the system analyzes it using a deep learning model to analyze whether it is damaged and automatically classify the type of damage. By providing repair and maintenance quotes for a significant part, the system provides economically repaired by providing comparative adjustment information on repair costs to drivers who are particularly concerned about the market prices of parts and maintenance services. Through the existing bulletin board, you can exchange and share information about parts by sharing various information on repair and maintenance. This paper provides in detail the average market price per type of damage during automobile repair and maintenance, helping drivers who do not know the details of parts and maintenance services to receive reasonable quotes by providing price information.

Generally, SAW device, which uses Time Domain Sampling, requires high speed AD converter because SAW device (TDS) needs high sampling speed as much as its high data speed. However, the high price of AD converter discourages makers from using it. On the other hand, SAW device, which uses Frequency Domain Sampling, does not required high speed AD converter because SAW device (FDS) does not need high sampling speed. It is very efficient in price comparison to its performance because high processing speed of SAW device (FDS) can be implemented using low price Embedded Systems. The purpose of the thesis is to solve the issues above by designing and realizing SAW device (FDS) using SAW sensor for TDS.
