This study investigated physical properties and combustion gas characteristics for 8 types of wood pellets (4 domestic and 4 imported products) distributed in the domestic market. Results showed that most pellet types were first-grade pellets in the wood pellet quality standards in Korea with the exception of 3 pellet types from K company (second-grade in mechanical durability), G company (off-grade in nitrogen content) and P company (second-grade in ash percentage). Mixed pellets which contained more lignin and sap content were higher in mechanical durability (%) than that of white pellets. From the combustion gas analysis results, NOx emitted from all pellets combustion was at acceptable levels for national emission standard of the Clean Air Conservation Act except for pellets from G company. In addition, CO levels from all types of wood pellets were acceptable except for pellets from D company and domestic pellets were higher CO levels than imported pellets. These results indicate the higher CO levels in domestic pellets due to the usage of forest thinning materials including logging debris which usually had the high content of bark.

High temperature operating test, temperature humidity test and temperature cycling were performed at various test levels for solid aluminum electrolyte capacitors made by domestic manufacturing company and foreign advanced manufacturing company. It was found that main failure mode of solid aluminum electrolyte capacitors was the decrease of their capacitances. The decrease of their capacitances has the same pattern in these tests. Test result for comparison of characteristics between domestic products and foreign advanced products shows that domestic products have the shorter lifetime and their capacitances decrease more rapidly in high temperature operating test and temperature humidity test. Also in these tests, accelerated tests for high temperature operating test and temperature humidity test were developed.

The purpose of this study is to systematize various clothing production methods that domestic fashion brands are utilizing to produce fashion products, and to propose effective clothing production methods according to the characteristics. The research methods are contents analysis method of the literatures, articles, reports, and interviewing method of the practitioners who are in charge of the production of fashion. First, the clothing production methods of the domestic fashion brands are categorized as follows. It is divided into a fashion brand management method and a promotion company entrustment method based on who carries out the clothing production and management. The fashion brand management method is subdivided into the 'rental-production', 'CMT', and 'self-production' methods. All three methods are performed at domestic and global sourcing, but the CMT method is more utilized at the global sourcing. The promotion company entrustment method is subdivided into the 'full consignment production method', the 'CMT method involving promotion company', and 'direct buying method by promotion company'. All methods are performed at domestic and global sourcing. Second, the results of reviewing effective clothing production methods, according to characteristics are as follows. If fashion brands control the production and management, they use all three fashion brand management methods. The fashion brands use the promotion company entrustment method when they wants to offer special products, or the number of items is large, or the production management is difficult, or the manpower and equipment size is reduced. The domestic sourcing is utilized by fashion brands and promotion companies when production management is required for high quality apparel production, in case of trendy and complex designs, spot production, and in small quantity production. The global sourcing is utilized by fashion brands and promotion companies when it comes to lowering the production cost, fashion brands preferred the mass production of apparel with design that can be pre-planned.

Korean small and medium industrial company might be better if we make continuous effect to improve the quality activities based on the factors which are presented in this paper. The adaptation of ISO 9000 has brought about some significant positive effects to domestic quality systems. However, some negative results occurred in domestic industries' rushing to fulfill the requirements of these new quality systems. This study is conducted using the data collected from 153 manufacturing companies. The primary objective of this research is to provide the efficient implementation process of ISO 9000 certification on the basis of total quality management. This analysis is able to apply for domestic industrial company to establish and maintain the development of quality systems.
