U-commerce에서 개인화가 미치는 영향에 대한 연구
한현수(Hyun-Soo Han),임동수(Dong-Su Lim) 한국전자거래학회 2008 한국전자거래학회 심포지움 및 기타간행물 Vol.- No.-
U-commerce의 특징중 가장 핵심이 되는것은 Personalization(개인화)이이며, E-commerce와 M-commerce의 Personalization과 U-commerce상의 Personalization의 차이를 이해하는 것이 필요하다. 이 연구에서는 U-commerce 예상 어플리케이션을 통하여 개인화 변수를 확인하고 그것이 지각된 수용가치에 어떻게 영향을 끼치며 수용가치가 U-commerce의 수용의도에 어떤 영향을 미치는지를 조사하였다. This paper is to provide the guideline of U-commerce Adoption In the Ubiquitous environment. Personalization is the Key in U-commerce. The guideline helps the understand difference personalization in U-commerce with M-commerce or E-commerce. we described U-commerce’s prospective applications and personalization characteristics. So, according to TAM, we described what the perceived values of adoption and how perceived values of adoption can effect to adoption intention.

Objectives: The concentrations and distribution characteristics of volatile organic compounds (VOCs) in an industrial complex and surrouding affected residential areas were investigated in an effort to support the efficient management of VOCs. Methods: The atmospheric concentrations of VOCs were analyzed at sites around the Sihwa-Banwol complex located in the cities of Siheung and Ansan and in the surrounding affected residential areas. The appearance of VOCs and the characteristics of their temporal and spatial distribution were evaluated. Results: The total VOC concentrations in the industrial complex were detected at 1.9-2.3 times higher than in the affected areas, but the daily VOCs distributions showed similar patterns in both sites. In particular, it was confirmed that the composition ratio of the VOCs and concentration fluctuations over time in the affected areas are similar to those in the adjacent industrial complex. VOC levels in the affected areas were higher than in residential areas in cities without an industrial complex. Conclusions: VOCs in residential areas near an industrial complex were highly distributed due to the influence of continuous pollutant emissions from the industrial complex. Therefore, the management of VOCs in the atmosphere of the affected area is important for identifying and managing the sources of VOCs detected in high concentrations in the industrial complex.

관절경하에서 슬개골건 : 골을 이용한 전방십자인대 재건술
한현수,안진환,한수홍 대한슬관절학회 1994 대한슬관절학회지 Vol.6 No.1
Anterior cruciate ligament is a very important structure for stablility of knee joint. Because injured anterior cruciate ligamentedled to the instability of knee, tear of meniscus, degenerative arthritis and decreased life activity, various operative treatment have been described for the treatment of chronic anterior cruciate ligament insufficiency. We analyzed the 31 cases who had taken the reconstruction surgery of anterior cruciate ligament using bone-patellar tendon-bone graft under arthroscopy from September 1988 to October 1992. The average follow up period was 26 months. The results were as follows : 1. Of the 31 Knees, 21(69 %) knees were caused by sport injury. 28(90 %) patients were male and average age was 24.9 years old. 2. Duration of the interval from injuries to operation was average 27,4 months. In the physical examination for instability in preoperative period, 29(94 %) knees were positive in anterior drawer test, 31(100%) knees Lachmann's test and 27(87 %) knees in pivot shift test. In the last follow up, 27(87 %) knees were negative in anterior drawer test, 19 (61 %) knees negative and 6(20 %) knees trace in Lachmann's test and 27(87 %) knees negative in pivot shift test. 3. 24(77 %) knees were combined with meniscal injury. 4 knees were treated by arthroscopic meniscorrhapy and 17 knees by arthroscopic meniscectomy. 4. The patients were evaluated by Marshall's knee rating scale. 25(81%) of 31 Knees were estimated as excellent or good result. Average Marshall scoring scale was 33.8 point at preoperative and 45.9 point at the last follow up. Average Lysholm knee scoring scale was 74 point at preoperative and 94 point at the last follow up. According to KT-1000 arthrometer, 25(81%) of 31 knees were estimated below 2mm by side to side difference with manual maximum values at last follow up.
