The biological magnification of Pb, Cu, Zn and Fe from soil or water column in water chestnut, Trapa japonica and relationship between the concentration of Pb, Cu, Zn and Fe in Trapa japonica and in adjacent soil or water column were investigated in the Chonju river, Chonju city and suburb's river. At each of 5 sampling sites, 5 Trapa japonica individuals, water and soil were collected in every week during 4 months, separated into leaf, stem and root portions, stored in a deep freezer at -70℃ and analysed for total Pb, Cu, Zn and Fe by Trace Element Analyser 3000. The amounts of biological magnification of heavy metal in Trapa japonica were Pb(213.9㎍/g), Cu(618.1㎍/g), Zn(2346.7㎍/g) and Fe(6078.5㎍/g). The concentration of Pb, Cu, Zn and Fe in the leaf, stem and root of Trapa japonica was founded that concentration in leaf and stem was increased in the sequence Pb<Cu<Fe<Zn and in root was increased in the sequence Pb<Cu<Zn<Fe. The amount of biological magnification in the leaf, stem and root of Trapa japonica was generally increased in the sequence leaf<stem<root. Statistical Analysis suggested that the significant portion of Pb, Cu or Zn Content in Trapa japonica was derived from soil. The concentration of Pb, Cu and Zn in Trapa japonica relatively indicates the heavy metal content of soil in river area.

Objectives. This study prospectively evaluated postthyroidectomy syndrome (PTS) through objective and subjective voice changes following thyroidectomy of open vs. endoscopic thyroidectomy. Methods. A prospective clinical trial (SCHBC IRB 09 26) was performed from Jan 2008 to Aug 2010 to compare the open thyroidectomy (OPEN group) and endoscopic thyroidectomy (ENDO group). Of the 110 patients, 75 completed the evaluation before and 1 and 6 months after surgery. Subjective parameters included perceptual analysis (GRBAS [grade, roughness, breathiness, asthenia, and strain] scale), stroboscopic or flexible fiberscopic analysis, voice handicap index, and 5-point visual analog scales for vocal fatigue, singing difficulty, difficulty with high-pitch phonation, and neck discomfort. Objective parameters included acoustic, aerodynamic analysis and the electroglottograph. Results. For the ENDO group (n=36), the operation time was longer than in the OPEN group (n=39; P<0.01). For the OPEN group, two objective and five subjective parameters were worse 1 month postoperatively; of these, two subjective parameters persisted for 6 months (P<0.05). For the ENDO group, three objective and six subjective parameters were worse 1 month postoperatively, and three of the subjective parameters persisted 6 months postoperatively (P<0.05). Conclusion. PTS really exists following simple thyroidectomy and are very common for both OPEN and ENDO groups. Most of the parameters improved gradually over time, but some subjective changes persisted 6 months postoperatively.

This paper suggests a method to evaluate and measure customer-centric web service quality of tourism web sites. The method is based on Quality Function Development(QFD) and by considering pre-visitors' priority requirements, strategies by the Korea National Tourism Organization's(KNTO) global market e-positioning and elements used to measure web service quality of tourism web sites. The proposed QFD process and the three proposed customer-centric tourism web service quality frameworks are to be applied to restructure the Tour2Korea.com web site and Tour Hub Network of Korea in 2005 for marketing in the three major overseas markets-America and Europe. 본 연구는 미국 및 유럽 등 원거리 관광객들 중심의 관광 사이트의 웹 서비스 품질을 평가하고 반영하기 위한 새로운 방법을 소개한다. 이 방법은 먼저 품질기능전개(QFD)를 기반으로 원거리 관광객들의 우선적인 요구사항을 고객의 목소리로 반영하고, 한국관광공사의 미국 및 유럽 등 원거리 시장에 대한 e-포지셔닝 전략을 고려하여 관광 사이트의 웹 서비스 품질을 향상시킬 수 있는 주요 서비스 차원을 도출한다. 제안된 품질기능전개 방법론과 본 연구에서 제시한 주요 서비스 품질요인은 한국관광공사의 Tour2korea.com의 웹사이트와 원거리 외국인 관광객들을 위한 Hub-Network 웹사이트의 설계 등 많은 관광 웹사이트에 적용될 수 있을 것이다.

This paper proposes 2 problems of Internet Marketing. Firstly, nowadays many people are aware of Web Service and the services that are available in cyberspace. However they are not fully aware of the concepts and range of Web Services. Secondly, most of the research of Internet Marketing focuses on the service quality of cyber shopping using SERVQUAL in relationship to service quality of shopping malls. Therefore they have a lot of limitations because they do not understand all the media characteristics of Internet. Basically the Internet has service parts and also has characteristics of new advertising. But many research papers do not consider these respects. The purpose of this paper is to study of the effects of Web Service Quality on Internet Commerce Transactions. To accomplish the purpose of this paper effectively, theoretical background of web services was reviewed briefly. We defined Web Services and categorized them. We found that the components of Web Service Quality are Information Providing Service Quality and Advertising Service Quality. Factor analysis is conducted according to the dimensions of each component. We conducted Path analysis how these components affect buyers' attitude and buyers' attitude affect revisit intentions and buyer intentions. The results show that strategies of cyber brand construction are better than strategies of selling to web surfers. The strategies of cyber brand construction are related to buying in that customers increase their visits to the entrepreneur's Web site and this increases the loyalty to that site therefore this is related to buying habits.
