Quality of manufactured goods under mass production system depends largely upon accuracy rate of quality control. Tolerance analysis is a useful method to set up a guide for inspection of product. However it usually would happen that strict tolerance provoke very high manufacturing cost. It is the main concern of tolerance analysis to find optimal values of tolerance to satisfy both quality and cost. This paper presents three tolerance analysis methods and its corresponding results upon automobile steering system to analysis the merits and demerits of each method.

Since the Korea-Chile FTA in 2003, eight FTAs are now in force including Korea-EU and Korea-US FTA. The government anticipate that FTAs increase the GDP of Korea. Government-related research institutes officially reports the positive economic impact in Korea. However, the report does not show that how much Busan economy is affected by the FTAs. For this reason, we study the economic effects of FTAs in Busan. We compare the trade statistics before and after the time each FTA is in force. The resulting figures show that the exports and trades of Busan with the FTA nations increased significantly after the enforcement. For example, the exports to Chile increased by 273% when we compare the three-year average trade. We also construct an econometrics model to estimate the price elasticity. The estimated elasticity of exports for manufactured goods is 1.38 while that of imports is 0.83. Among the manufacturing industry, machinery has the highest price elasticity, 1.8. The average tariff for manufactured goods is 3.9% for FTA nations, while that is 5.8% for Busan. This higher price fall in Busan is offset by the lower price elasticity to make Busan's export increase be greater than Busan's import increase. Busan's export increases by 4.8% while import increases by 3.7%. So, it is expected to be added to the annual trade surplus of approximately $107million.

This survey was conducted to monitor the adulteration of sesame oil circulated in Gwangju, 2007. A total of 60 samples was tested by analysis of fatty acid composition. Of these samples, 22 were from large-scale manufacturer, 25 were from small-scale manufacturer and 13 from Bangagan. First of all, in goods manufactured by large-scale company, there are no sesame oils where linolenic acid($C_{18:3}$) exceed regulatory guidance(0.5%). 5 samples from small-scale manufacturer contained linolenic acid from 0.90% to 8.38%, which means that they have other cooking oil, such as com oil, soybean oil and rape seed oil. Among Bangagan goods, only one sample have 1.20% of linolenic acid. On the other hand erucic acid($C_{22:1}$) was not detected in 60 samples at all, which means that they were not adulterated with rape seed oil. And among 6 samples of exceeding 0.5% of linolenic acid and 12 samples from Bangagan, 13 of them had benzo(a)pyrene from $0.2{\mu}g/kg\;to\;0.7{\mu}g/kg$ and the other 5 samples did not.

This study was conducted to gather the basic data on the spread of the domestic kiwifruits, and the development of the manufactured goods and the health functional foods produced using kiwifruits. We determined the chemical compositions of four types of kiwifruits cultivated in Korea, Daeheung, Bidan, Haegeum and Hayward. In addition, we measured the anti-microbial activities and cytotoxicities of these types of kiwifruits. The vitamin C contents of the kiwifruits increased in the order of Bidan (93.82 mg/100 g), Daeheung (85.89 mg/100 g), Haegeum (83.73 mg/100 g) and Hayward (75.28 mg/100 g). The total amino acids contents per 100 g of kiwifruit (dry weight basis) were 483.97 mg (Haegeum), 453.08 mg (Hayward), 437.27 mg (Bidan) and 369.35 mg (Daeheung). The K and Ca contents of the kiwifruits ranged from 14.56~37.12 mg/L and 1.94~8.24 mg/L, respectively; however, the Fe, Mg, Zn and Cr contents all less than 1.83 mg/L. The antimicrobial activities of methanol extracts of kiwifruits against five gram positive bacteria at concentration of 2,000 mg/L in terms of inhibition diameter ranged from 8.8~12.8mm, while raged from 9.2~13.1mm against three gram negative strains of bacteria. The hyperplasia inhibition of lung cancer cells (Calus-6) by 800 mg/L kiwifruits extracts of Bidan, Haegeum, Daeheung and Hayward kiwifruits were 21.2%, 9.5%, 6.7% and 5.0%, respectively. Consequently, it was assumed that kiwifruits was rich in vitamin C, amino acids and K, and that they would therefore be useful in processed goods.

Most published work on product quality focuses on manufactured goods. The subject of service quality has received less attention. This distinction is important because some of the quality-improving strategies avaliable to manufacturers may be inappropriate for service firms. Services are performances, not objects. They are often produced in the presence of the customer, as in the cause of hotel restaurant services, quality occurs during service delivery, usually in an interaction between the customer and contact personnel of service firm. for this reason, service quality is highly dependent on the performance of employees, an organizational resource that cannot be controlled to the degree that components of tangible goods can be engineered. The study has begun as a basic study for customer satisfaction-oriented management in understanding the service quality of food & beverage products and through a systematic analysis of it. The major purpose of the study was to examine the relationship of the customer satisfaction and service quality in consideration of reliability, empathy, responsiveness, tangibility and assurance. An empirical research was conducted based on the previous theoretical studies. 286 customer at first class hotels in Seoul were selected as samples of this study. The time period of research was from February through March 1999, and answers were processed by SAS to yield frequency analysis, multivariate statistical analysis and regression analysis. The finding of the statistical treatment are frequencies, factor analysis, multiple regression analysis, path analysis. SERVQUAL method was used the service quality evaluation methods. After factor analysis, it was resulted to 3 factors. those were factor 1(assurance.empathy.responsiveness), factor 2(reliability), factor 3(tangibility). The findings of the statistical treatment are as follows. First, the attribute measurement of performance service quality was affected by customer satisfaction. Second, the attribute measurement of performance service qualify was affected by repurchase intention. Third, The attribute measurement of performance customer satisfaction was affected by repurchase intention. The result of study model was followed, service quality was affected repurchase intention than customer satisfaction. indirected effect through, service duality and customer satisfaction was affected repurchase intention.

Foreign outsourcing, otherwise known as off-shoring, has become a matter of intense public debate and great concern in both developed countries and developing countries. Yet, there is a lack of good data on foreign outsourcing since the early 1990's. This paper presents updated measures of foreign outsourcing for the recent period. Its main findings are that the share of foreign-sourced goods in total manufactured inputs almost doubled-from 12.4 percent to 22.7 percent between 1987 and 2003. I then look at the relationship between the measure of foreign outsourcing activity and wages in US manufacturing industries in recent years from 1998 to 2003. The results show that for all workers, the outsourcing level is statistically significantly and negatively associated with industry wage premiums. The estimate suggests that a magnitude of 0.9 - a 9% decrease in industry wage premiums tends to accompany a 10% increase in industry outsourcing level. Outsourcing has a bigger effect on the less-skilled workers-industry outsourcing level increases by 10% and industry wage premiums decrease by about 11% in the case of less-skilled workers.

Nonwoven fabrics have been widely used in various fields that include household, industrial, agricultural, medical goods, especially in the automobile industry. In this study, eco-friendly fiber materials were developed and investigated as a substitute material for polyester fibers in nonwovens. To make plant fiber bundles, stems of Indian mallow (IM), and Kuzu vine (KV) were retted; in addition, the non-cellulose component was partially removed. Plant fiber bundles and polyester fibers (P) were blended and needle punched to produce nonwovens. Five kinds of nonwovens were manufactured: P100 (Polyester 100%), IM10 (IM 10% and Polyester 90%), IM20 (IM 20% and Polyester 80%), KV10 (KV 10% and Polyester 90%), and KV20 (KV 20% and Polyester 80%). The color values, surface appearance, tensile strength, elongation, tear strength, abrasion strength, flexstiffness, moisture regain, water or oil absorbency, and static electricity of manufactured nonwovens are investigated. As the blended ratios of IM or KV increased, the brightness of nonwovens decreased compared to that of polyester 100%. Tensile strength, tear strength, abrasion strength, and flexstiffness of IM10 as well as KV10 were higher than those of P100, IM20, and KV20, resulting from the influence of the structure and properties of nonwoven fibers. Moisture regain and water or oil absorbency increased, while static electricity decreased in proportion to the amount of plant fibers. IM or KV and polyester blended nonwovens showed improved properties over P100 that could be substituted for P100 as a novel material for textiles.

This study analyzed the pattern of Myanmar's trade with east asia countries, Korea, China and Japan. By using RCA index and TSI index, the comparative advantage and trade specialization of Myanmar are analyzed. UN COMTRADE data from 2012 to 2014 is analyzed. After the economic sanction against Myanmar was lifted, the volume of trade of Myanmar was increased sharply as well as the trade structure is changed. The volume of trade in primary industry is decreased while the manufactured industry takes more share of trade volume. The comparative advantage of manufactured industries took more steps while those of primary industries lose. In the trade with Korea, China and Japan, Myanmar exports labor intensive products and primary goods. Trade relationship beteen Korea and Myanmar is analyzed to be primary step, while China's and Japan's are going to be advanced. China and Japan are entering to the stage of international value chain system by using abundant labor of Myanmar.

The research is a study on the effects of MMORPG (Massively Multi-player Online Role Playing Game) utilized in educational program. We investigated the possibilities of online game as an educational tool, especially in the field of economy education. Students have been taught market, price, profit, scarcity of goods etc., and then they played an online game we provided. Students manufactured cyber goods and also sold or bought various materials to maximize their profits. A experimental group was compared with a control group on measures of economic self-efficacy, motivation for economic learning, and attitude for economic learning, economic self-efficacy and motivation for economic leaning scales consist of 2 factors and attitude for economic leaning consists of 1 factor. Participants were 5th grade elementary school students(experimental group: 154, control group: 158). After the experiment, students' self-efficacy and motivations for economy learning have increased significantly. It has been found that students understand more easily the difficult economic terms such as' inflation', 'price setting', 'scarcity of goods etc. Their motivations for economy learning also increased significantly. This result indicates that online games have the potentiality that can be utilized as an educational tool.
