  • 가상대학 강좌는 누구나 쉽게 강의를 청취할 수 있는 장점 때문에 많은 학생들에게 인기를 얻고 있다. 그러나, 가상 대학 강의에서는 본인신분을 확인 하는 과정이 매우 어렵기 때문에 본 논문에서는 가상대학 강좌를 수강할 경우에 본인 여부를 확인하기위해서 RFID 카드 방식을 이용해서 본인인증여부를 확인 할 수 있는 시스템을 개발하였다. 뿐만 아니라 본 시스템은 실시간으로 신분을 확인할 수 있는 인식 알고리즘 및 쌍방향 가상 질문 시스템을 개발하였다. 컴퓨터 모의 실험결과 쌍방향 가상 수업 시스템이 이해하지 못한 학생을 고려하지 않은 기존의 단방향 가상 수업시스템보다 훨씬 효과적인 것을 입증했다.

  • The wording of Article 18 shows that a statement made by or other conduct of the offeree indicating assent to an offer is an acceptance. Meanwhile, Article 19 states that this reply with different terms is a rejection of the offer and constitutes a counteroffer. For example, additional or different terms relating, among other things, to the price, payment, quality and quantity of the goods, place and time of delivery, extent of one party's liability to the other, or the settlement of disputes are considered to alter the terms of the offer materially. However, this reply with different terms which do not materially alter the terms of the offer constitutes an acceptance unless the offer or, without undue delay, objects orally to the discrepancy or dispatches a notice to that effect. As a result, the acceptance depends on whether different terms are material or not. CIETEC holds that the deletion of contract violation liability clause is not equal to an alteration to the extent of one party's liability to the other as stipulated in Article 19(3) of the CISG. In addition, CIETAC recognizes that one party had orally accepted the modifications made to the sales confirmation, with even China declaring against an oral contract. Lastly, CIETAC holds that the sales confirmation has been established when both parties signed on the sales confirmation instead of the acceptance being effective. Korean companies should, thus, note these issues when they solve disputes at CIETAC.

  • The challenges of rapidly growing numbers of mobile nodes in IPv6-based networks are being faced by mobile computing researchers worldwide. Recently, IETF has standardized Mobile IPv6 and Fast Handover for Mobile IPv6(FMIPv6) for supporting IPv6 mobility. Even though existing literatures have asserted that FMIPv6 generally improves MIPv6 in terms of handover speed, they did not carefully consider the details of the whole handover procedures. Therefore, in conventional protocols, the handover process reveals numerous problems manifested by a time-consuming network layer based movement detection and latency in configuring a new care of address with confirmation. In this article, we study the impact of the address configuration and confirmation procedure on the IP handover latency. To mitigate such effects, we propose a new scheme which can reduce the latency taken by the movement detection, address configuration and confirmation from the whole handover latency. Furthermore, a mathematical analysis is provided to show the benefits of our scheme. In the analysis, various parameters are used to compare our scheme with the current procedures, while our approach is focused on the reduction of handover latency. Finally, we demonstrate total handover scenarios for the proposed techniques and discussed the major factors which contribute to the handover latency.

  • Stepping into the technological boom time, Vietnam has integrated into the trends of using Fintech applications as a new means of payment. This article evaluates the relationship between perceived security (including service security and platform security), knowledge, confirmation, perceived usefulness, satisfaction, attitude and lastly enterprise's images regarding the service and continuous intention to use Fintech services. The survey results of 352 Vietnamese customers using Fintech services, reliability test and extended post-acceptance model (EPAM) which is based on PAM and ECT models. From the survey, we further found out that perceived security (BSS) has no direct impact on continued intention to use, while perceived security (BSS) has positive impact on confirmation (CON), similarly, perceived usefulness (PU) and user's satisfaction (SES). Knowledge of the Mobile Fintech payment service (KNOW) has a positive impact on perceived security (BSS). Confirmation (CON) has a positive influence on perceived usefulness but in the meanwhile it has created a negative impact on user's satisfaction (SES). From the survey it can also tell that user's attitude (ATT) and enterprise image (IMG) both have a positive impact on continual intention to use Fintech services. From the research results, we also propose some recommendation to enhance the continual intention to use Fintech services in Vietnam.

  • Object: To evaluate the efficiencies of the arthroscopic rotator cuff surgery which is Performed without the traction system in the lateral decubitus position. Methods: Twenty-nine cases of the arthroscopic rotator cuff surgery performed without the traction system in the lateral decubitus position were studied from February, 2002 to January, 2005. We performed a repair using the arthroscopic debridement and the arthroscopic rotator cuff repair, or using the mini-open incision technique after the confirmation of rotator cuff tear, then, the arthroscopic subacromial decompression was performed after the confirmation of subacromial lesions Results: We could easily find the subscapularis tear which was often overlooked in the arthroscopic rotator cuff surgery performed with the traction surgery by the relaxation of the subscapularis, as the arm position was internally rotate about 45 to 70 degrees from abducted position. We found that the operation time was reduced 14 minutes shorter than the operation time of the controlled group which had the surgery with the traction system on the average. We also found that there were no neurovascular complications from all cases. Conclusions: The arthroscopic rotator cuff surgery without traction system in the lateral decubitus position provided the better visual field, easy manipulation of the joint and reducing operation time.

  • As meters become digital and smart, energy data such as electricity, gas, heat, and water can be accurately and efficiently measured with a smart meter, providing consumers with data on energy used, so that real-time demand response and energy management services can be utilized. Although it is developing from a simple metering system to a smart metering industry to create a high value-added industry fused with ICT, illegal counterfeiting of electronic meters is causing problems in intelligent crimes such as manipulation and hacking of SW. The meter not only allows forgery of the meter data through arbitrary manipulation of the SW, but also leaves a fatal error in the metering performance, so that the OIML requires the validation of the SW from the authorized institution. In order to solve this problem, a quantitative confirmation device was developed in order to eradicate the act of cheating the fuel oil quantity through encoder pulse operation and program modulation, etc. In order to prevent the act of deceiving the lubricator, a device capable of checking pulse forgery was developed, manufactured, and verified. In addition, the performance of the device was verified by conducting an experiment on the meter being used in the actual field. It is judged that the developed quantitative confirmation device can be applied to other flow meters other than lubricators, and in this case, accurate measurement can be induced.

  • Background: Modified toluidine blue staining (MTBs) is a simple, inexpensive and time saving method to detect H. pylori in gastric biopsy specimens. As a metachromatic stain, it simultaneously highlights intestinal metaplasia, a gastric cancer precancerous lesion. The aim of this study was to assess the reliability of MTBs compared with hematoxylin-eosin (H&E) for H. pylori detection using immunoperoxidase staining as the gold standard. This technique would be beneficial for a routine diagnosis and confirmation of H. pylori eradication in developing countries where endoscopic-based approaches are dominant. Materials and Methods: Esophagogastroduodenoscopy with triple site gastric biopsies was undertaken in 207 dyspeptic patients at Thammasat University Hospital, Thailand between 1997 and 1999. H&E, MTBs and immunoperoxidase staining were applied to each specimen. The presence or absence of H. pylori with each stain was interpreted separately and the sensitivity, specificity, positive and negative predictive values of H&E and MTBs were calculated. Results: A total of 282 specimens from 207 patients were evaluated. Using immunoperoxidase staining, organisms were positive in 117 specimens (41%). MTBs proved almost equally sensitive as immunoperoxidase (99%) and significantly more sensitive than H&E (85%). It has comparable specificity (96% vs 96%), PPV (95% vs 94%), and NPV (99% vs 90%) to H&E, using immunoperoxidase staining as gold standard. MTBs compared with immunoperoxidase staining, is cheaper (2 USD vs 12 USD) and faster (20 min vs 16 hrs) compared to immunoperoxidase staining. Conclusions: MTBs is effective, economical and easy to use in daily practice for the detection of H. pylori in gastric biopsy specimens. In addition to saving time in evaluating H. pylori associated gastritis, with a high sensitivity and ability to demonstrate intestinal metaplasia, the technique may have a role in confirmation of H. pylori eradication for gastric cancer prevention in a developing country setting.
