In this study, ferrite/rubber composite specimens have prepared by molding and curing the mixture of matrix silicon rubber and three kinds of filler particle Mn-Zn/Ni-Zn/Ni₂Y ferrite which are synthesized by the coprecipitation mehtod. The mixing ratio of three kinds of ferrite filler paticle gave variety to adjust the material constant of composite microwave absorbers. Material constants of composite specimens were calculated from the measured variables(s-parameter) over the frequency range from 1 to 12 GHz by means of Network Analyzer(HP8722D) with a co-axial type air line. The reflection loss was calculated from material constants on the impedance matching map utilizing simplex method. By chaging mixing ratio of three kinds of ferrite filler particle, the frequency range over than 20dB were relatively broaden and maximum reflection loss were remarkably reduced to others specimens excepted specimen D. Finally, it could make microwave absorber to be used for C-band frequency range.

This paper describes development of low cost precision machine that has combined the Build-in Motor with a vacuum chuck. This study mainly aims to find out a cutting condition for maintaining optimum surface condition and to examine cutting characteristics of the precision machine that is equipped by diamond bites. The cutting materials is Al alloy. Several experiments were carried out to find out the main factors that affect the surface roughness such as principal axis RPM(rotation per minute), feeding speed, and cutting depth. As a result, we obtain The optimum cutting condition of the developed precision machine.

Feasibility of simultaneous removal of organic and nitrogen is evaluated as applying microbial entrapping method to treat fish processing wastewater. Treatability test is conducted immobilizing activated sludge from municipal sewage treatment plant to gel matrix made of cellulose triacetate. Stable operation can be possible when applying organic and nitrogen loading rate increasingly to wastewater treatment system composed of anoxic and oxic tank. Organic loading rate and nitrogen loading rate are applied 0.65-1.72kg COD/㎥/d and 0.119-0.317kg T-N/㎥/d, respectively. In case of wastewater from fish processing plant used in this study, it is evaluated that 0.3kg T- N/㎥/d is upper limit of applicable space loading rate because effluent T-N concentration is exceed 60mg/L, legal effluent dishargeable limit of T-N concentration in Korea, when space loading rate is exceed 0.3kg T-N/㎥/d. It is evaluated that nitrification of system is performed efficiently regardless fo variation of applied loading rate because removal efficiency of NH_(4)^(+)-N is relatively constant when the applied NH_(4)^(+)-N loading rate is increased gradually, while decrease of T-N removal efficiency is apparent when the applied loading rate is increased gradually. Nitrate removal efficiency in this study is varied from 98.62% to 99.51% depending on applied loading rate, while nitrification efficiency of oxic reactor is varied from 94.0% to 96.9%. It is showed that COD removal efficiency is varied from 94.2% to 96.6% and T-N removal efficiency is varied from 73.4% to 83.4% depending on loading rate applied in this study.

중국의 급속한 성장에 따라, 중국인들의 생활수준은 엄청난 진보를 이루어왔다. 동시에, 그들의 소비 패턴 또한 빠르게 변화하고 있다. 중국인들의 엄청난 구매력을 고려하여, 많은 국제적인 할인점들이 중국 시장에 진입하였다. 이러한 거대한 다국적기업들이 북경 도시지역에서 그들의 활동을 지속적으로 확장해 왔지만, 서비스 품질과 고객충성도와의 관계에 대한 연구는 없었다. 그러므로 본 저자는 외국 할인점들에 대한 소비자 만족도의 정도와 점포 충성도에 대한 서비스 품질의 영향을 분석하였다. 네 가지의 주요 외국 할인점, 즉, 미국의 월마트, 프랑스의 까르프, 일본의 이토-요카도, 한국의 롯데마트 등을 대상으로 결과를 도출하였다. Along with the rapid development of Chinese economy, Chinese standard of living has achieved a significant improvement. At the same time, their consumption pattern is also rapidly changing. In order to take advantage of enormous purchasing power, many international discount stores entered Chinese market. Although these multinational giants continued to expand their operation in Beijing metro area, there is no research about the relationship between service quality and customer loyalty. Therefore, we analyzed the degree of consumer satisfaction on foreign discount stores and the influence of service quality on store loyalty. The current study used four major foreign discount stores such as Wal-Mart from the U.S., Carrefour from France, Ito-Yokado from Japan and Lotte-Mart from Korea.

Now, the Korean consumer market enters into the stage of the advanced country type`s mature consumption, totally different from the consumption of the past, and among these changes, the quality enhancement and bipo-larity of the consumption show clearly the rising trends together with the popularization of the Masstige Brand due to the big expansion of the quantity. Unlike the old luxury brands, available only to the rich people in the past, the Masstige Brands are tagged with reasonable and affordable prices and provide the consumers with the good quality and convenient sensibilities as good as the old famous brands, which have become new high-class brands for the middle-income class. As the middle-come people get more income and are eager to live a better life, the Masstige Brands rise fast. Therefore, the study is aimed at examining the consumer- related factors affecting the purchase of the Masstige Brands on the basis of the fashion brands. In other words, the factors affecting the formation of the positive purchasing intentions of consumers will be verified by examining the influence of such factors, as the consumer value, brand charisma, attitude and loyalty, the variables affecting the purchasing intentions of the Masstige Brands, which are found out through the proceeding researches. As the result of the verification on the assumption, it is found out that the consumer value has a positive influence on the brand charisma. Also, it is found out that the consumer value has a positive influence on the brand attitude. And, it is discovered that the brand charisma has a positive influence on the brand loyalty. It is shown that the brand attitude has a positive influence on the brand loyalty. Lastly, it is indicated that the brand loyalty has a positive influence on the purchasing intention of consumers.

An intensive analysis was conducted of the maternal lineages of the Jeju native pigs (JNPs). A total of 100 mtDNA sequences from Asian wild boars (AWB), European wild boars (EWB), Asian domestic pigs (ADP), European domestic pigs (EDP), and JNPs were used for the phylogeny and network analyses. Two distinct JNP groups were found JNPA and JNPE in the Asian and European cluster. The maternal lineage of JNPE was the closest to that of EWB and a clear haplogroup sharing an identical haplotype (hap16) among 15 individuals of JNPE and 2 individuals of EWB was identified. However, except for hap18, no EDP shared any identical haplotypes with JNPE, suggesting that no obvious maternal contribution of EDP has occurred in JNPE in recent years. The possible existence of an additional and unknown path of maternal lineage from EDP into JNPE could therefore be postulated, in addition to those from AWB and ADP into the JNPA groups. Thus, JNPE appeared to have a pure maternal lineage that had no recent contact with EDP, and both the JNPA groups and JNPE are pure Jeju native pigs.
