The quantum theory of intraband magneto-optical transition in semiconductors introduced previously in terms of continued-fraction-based power-series-expansion technique is reviewed in connection with examination of temperature- and dimensional-dependence of the width in GaAs and CdS in which piezoelectric scattering is dominant. With the same values of the piezoelectriccoupling constantK and the expansion parameterethe width in two-dimensions increases with temperature as in three-dimensions.Furthermore, the width becomes smaller uniformly as the dimension is reduced in the direction of static magnetic eld in thequantum limit, which is physical. Therefore, the continued-fraction-based theory gives quite good interpretation of the acousticphonon scattering in the quantum limit.. 2003 Elsevier B.V. All rights reserved.

이현정(HyunJungLee) 한국체육학회 2007 한국체육학회지 Vol.46 No.3
본 연구의 목적은 선수 이미지와 선수와 브랜드의 이미지 일치성 및 브랜드 자산 간의 인과관계를 밝혀 선수 스폰서십이 국내 기업의 글로벌화를 위한 효과적인 마케팅 수단이 될 수 있도록 그 기초자료를 제시하는데 있다. 본 연구의 목적을 달성하기 위해서 20대에서 50대 이상의 남, 여 820명을 대상으로 일반적인 특성, 선수 이미지, 선수와 브랜드의 이미지 일치성, 브랜드 인지도 지각된 품질, 브랜드 이미지, 브랜드 충성도 요인을 파악하기 위한 설문조사를 실시하였다. 연구 분석은 USREL(ver 8.30) 프로그램을 이용하여 공분산구조분석을 실시하였다. 연구 결과 선수 이미지는 이미지 일치성, 브랜드 인지도 지각된 품질 브랜드 충성도에 영향을 미치는 것으로 나타났으며, 선수와 브랜드의 이미지 일치성은 지각된 품질 브랜드 이미지에 영향을 미치고 있는 것으로 나타났다. 그리고 브랜드 인지도는 지각된 품질에, 지각된 품질은 브랜드 이미지에, 브랜드 이미지는 브랜드 충성도에 영향을 미치는 것으로 나타났다. 이와 같이 선수 이미지와 선수와 브랜드의 이미지 일치성은 기업의 브랜드 자산 가치 상승에 영향을 미치고 있으므로 막대한 비용을 들여 선수 스폰서십을 실행하고자 하는 기업은 자사의 스폰서십 목표에 부합되는 이미지를 가진 선수를 전략적으로 선택하여 스폰서십의 효과성을 극대화하여야 한다. The purpose of this study was to analyze the casual relationship among athletes image, athlete-brand image congruence, and brand equity. To accomplish the objection of the research, 820 men and women ages from the twenties to the late fifties were picked out as the survey subjects to understand the general character, athlete image, athlete-brand image congruence, brand awareness, perceived quality, brand image, and brand loyalty factors. The collected data was analyzed through LISLEL(ver. 8.30) to obtain results for analysis of covariance structures. The result was that athlete image has a direct effect on athlete-brand image congruency, brand awareness, perceived quality, and brand loyalty. The athlete-brand image congruency turned out to have a direct effect on perceived quality and brand image. Also, brand awareness seen모d to have a direct effect on perceived quality, perceived quality have a direct effect on brand image, brand image have a direct effect on brand loyalty. Therefore, for those that are trying to do athlete sponsorship through immense cost, one would have to select the suitable athlete strategically to match the goal of sponsorship to maximize the effectiveness of endorsement.

본 연구의 목적은 여성 골프 선수들의 이미지 구성요인을 분석하고, 이들 이미지가 광고효과에 미치는 영향을 알아보는 것이다. 본 연구의 목적을 달성하기 위하여 서울과 경기 지역의 골프 참여자 369명을 설문 조사하였다. 연구 분석을 위해서 SPSS를 사용하여, 빈도 분석, 요인 분석, 신뢰도 분석, 다중회귀분석을 하였다. 결과는 다음과 같다; 첫째, 여성 골프 선수들의 이미지 요인은 프로페셔널리즘, 강인함, 외적매력, 친근감, 스타성의 5개 요인으로 구성되었다. 둘째, 여성 골프 선수들의 이미지가 구매의도에 미치는 영향을 규명한 결과 남자의 경우는 강인함 요인이, 여자의 경우는 친근감 요인이 영향을 미쳤다. 셋째, 여성 골프 선수들의 이미지가 로고의 호감도에 미치는 영향을 규명한 결과 남자의 경우는 외적매력 요인이, 여자의 경우는 외적매력 요인과 스타성 요인이 영향을 미쳤다. 넷째, 여성 골프 선수들의 이미지가 회사 이미지 부각에 미치는 영향을 규명한 결과 남자의 경우는 스타성 요인이, 여자의 경우는 프로페셔널리즘 요인이 영향을 미쳤다. The purpose of this study was to identify various "sub-images" that comprise a professional female golfer's overall image and analyze the advertising effects created by these sub-images. To facilitate this research, 369 golfers from the Seoul and Metropolitan Seoul region were surveyed and the data was run through SPSS(Windows Ver 12.0) to obtain results for frequency analysis, factor analysis, reliability analysis, analysis of multiple regression. The sub-images identified in the study were feminism, friendliness, toughness, professionalism and celebrity look. With regards to the effects of these sub-images on consumers' buying intentions, toughness was a significant factor for male consumers while friendliness was a significant factor for female consumers. On the effects of sub-images of female pro-golfers on consumers' impression/liking of product logos, feminism was a significant factor for male consumers while feminism and celebrity look were significant for female consumers. Finally, with the effects of sub-images on product company images, male consumers tended to find celebrity look important while professionalism was significant for female consumers.

The pomegranate (Punica granatum L.) is a promising source of functional food, which contains several phytochemicals that perform important roles in reducing the risk of pathological diseases. Chemical compositions, such as the total sugar, uronic acid, polyphenols, and anthocyanin contents, and radical scavenging activity were determined and compared among PEs from six different cultivation areas. Total anthocyanin contents (TAC) and total polyphenol contents (TPC) from various growing areas were detected in the following order, respectively: Spain (19.08 ㎍/mL)> Turkey (12.91 ㎍/mL)> Iran-A (6.67 ㎍/mL)> Taiwan (4.77 ㎍/mL)> Uzbekistan (1.88 ㎍/mL)> Iran-B (0.76 ㎍/mL) and Turkey (639.52 ㎍/mL)> Uzbekistan (502.19 ㎍/mL)> Spain (306.40 ㎍/mL)> Iran-B (249.20 ㎍/mL)> Taiwan (162.78 ㎍/mL)> Iran-A (143.93 ㎍/mL). PEs from six different cultivation areas were determined to vary in ellagic acid content from 8.90 ㎍/mL to 332.52 ㎍/mL. The amounts of total sugars in PE from Iran-A evidenced relatively high total sugar contents, but low uronic acid levels (11.92 ㎎/mL). DPPH (1,1-diphenyl-2-picrylhydrazyl) radical scavenging activities were as follows: Turkey> Uzbekistan ≫ Spain> Iran-B> Iran-A> Taiwan. ABTS [2,20-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)] radical scavenging activities were detected in the following order: Turkey≥ Uzbekistan≫ Spain> Iran-B> Iran-A> Taiwan. These results indicate that the PEs from Turkey with higher levels of TPC, TAC, ellagic acid, and higher radical scavenging activity may constitute a promising functional source for the prevention of several degenerative diseases.

The KSTAR superconducting (SC) magnets are cable-in-conduit-conductor (CICC) type magnets,which have a hundred parallel and twisted SC strands in a square conduit with a porosityof 0.36. They are cooled by the forced flow of supercritical helium with a 2bar pressure drop. Aflow imbalance test of the magnet cooling channels, one of the quality assurance processes, wasconducted using Ar gas at room temperature during the magnet’s manufacture, and was carriedout again after assembly. In those tests, the flow imbalance was measured to be within at most±10% for the all cooling channels, which satisfied the criterion (±20%). During individual testsof the magnets, the tendency of the flow imbalance showed that the mass flow rate of the upper(U) magnets PF1, PF2, PF5, PF6, and PF7 was higher than that of the lower (L) magnets. Onthe other hand, the mass flow rate of the upper magnets PF3 and PF4 was lower than that of thelower magnets. After assembly, this imbalance became more serious, and the measured mass flowrate of the upper magnets was higher than that of lower magnet at the PF2, PF3 PF4, and PF5magnets. This imbalance can influence the temperature and the pressure of supercritical helium, aswell as accelerate reversal flow and limit operating performance. In this paper, the helium behavioris analyzed and is explained to be due to the flow imbalance in the PF magnet.
