Electronic commerce has been threatening to address the transaction inefficiencies in international trade that is conducted through letters of credit(L/Cs) and other forms of traditional paper-based financial instruments. The replacement of traditional paper documets with electronic alternatives is becoming more of a relity within a number of business sectors. The conceptual model of electronic L/Cs presented in this paper is intended to provide a framework for discussing the development of a paperless credit. The TradeCard network provides a business-to-business e-commerce infrastructure that enables buyers and sellers to conduct and settle international trade transactions securely over the Internet. Sellers and Buyers should select the best payment methods of traditional L/Cs, electronic L/Cs, TradeCard, Bank Credit Card etc. in consideration of their business circumstances.

There have been always some difficulties in target setting and conditioning of acoustic performances or the Korean traditional music hall due mainly to the lack of the information on the sound radiation characteristics of Korean musical sources. As the 2nd experiment succeeding the previous study[1], the radiation characteristics of eight typical Korean traditional musical sources were investigated if precision. The selected musical sources were Geomungo, Haegeum (string), Piri, Taepyeongso (woodwind), Buk, Kwaengguari, Jing (drum), and male Pansori Chang (vocal Performance). The results show that the directivity pattern of each instrument is different and has their own directivity characteristics. Measured directional and spectral characteristics of traditional Korean music sources were implemented into the computation of architectural acoustic measures. Significant differences in the acoustic measures at receiver positions were observed between the results in using the omni-directional source and the directional one. In order to investigate the acoustical characteristics of the instruments depending on the spatial variation four different shapes of halls were introduced including rectangular, fan. horse-shoe and geometrical shapes. Room acoustical parameters such as RT, SPL, C80, LF, STI were calculated at each type or hall. As the results, It was found that the rectangular hall has the most high clarity. lateral energy and STI values among low shapes of halls. It is thought that the suggested source data and design method can be used as a basic reference in the future acoustic design of performance halls for the Korean traditional music.

Objectives Although there have been someone who pointed out declining tendency of pure traditional diagnosis, there are no objective survey results on present state of diagnosis among Korean Medicine Doctors (KMDs). So we did a descriptive survey study to show traditional diagnostic modality usage among them. Materials and methods: 73 samples of responded questionnaire in Busan area were collected and descriptively studied. Results (1) U code (in KCD-6) usage showed low level (28.7%). (2) Diagnostic apparatuses for traditional medicine are rarely used. For example, pulse diagnosis machine was reported to be used only by 9.7 % of KMDs. (3) KMDs still prefer the treatment based on pattern identification and symptomatic therapy rather than treatments based on disease identification of modern biomedicine. Conclusion Overall, the portion of pattern identification is still high among KMDs, some kind of diagnostic methods which support pattern identification showed lack of usage.

Objectives : The purpose of this review is to investigate the trends of traditional korean medicine treatments on frozen shoulder. Methods : We investigated the studies on traditional korean medicine treatments for frozen shoulder via searching 6 Korean web databases. As a result, 32 research papers were found to be analyzed according to their published year, the titles of journals, published institution, the types of study, the number of cases, the types of treatments, the instruments for assessment and ethical approvals. Results : 32 papers were published since 1989. The studies on traditional korean medicine treatments about frozen shoulder were mainly published in The journal of korean acupuncture & moxibustion medicine. 10 case series, 7 reviews, 6 non-randomized controlled trials, 5 randomized controlled trials and 4 case reports had been under research. In most of the research, the number of the cases were not enough. In 15 cases of the studies, various traditional korean medicine treatments were used to treat the symptoms. In 8 cases of the studies, one method was used to treat the symptoms. Range of motion(ROM) and visual analogue scale(VAS) were used as primary assessments. Among the 25 clinical studies, 5 of them were accepted by institutional review board(IRB). Conclusion : In this study, we analyzed the trends of traditional korean medicine treatments on frozen shoulder. Reviewing the domestic trends of studies on traditional korean medicine treatments for frozen shoulder and examining the strong and weak points of those treatments are essential for the future studies.

Objectives : It is sure that standardization of medical instruments is very important and necessary. Cupping therapy is one of the traditional oriental medical method, and it is necessary to set up a standard of cupping therapy and instruments. Methods : We select 3 major cupping instrument makers according to a questionnaire survey of 2001 oriental medical doctors. Dae Gun is A maker, Han Sol is B maker, Dong Bang is C maker. And with these air pumps we make experiments on stability by an inner impact test and a falling test. With these cups we check stability by an inner impact test and a disinfection test. And to know function of these instruments we test a negative pressure and maintain attached cups until 5 to 10minutes. Results : All results of experiments(impacted test, disinfection test, falling test) on stability of cups and air pumps are suitable for medical instrument. And the efficiency of 3 major makers shows various results. Negative pressure of B group is the highest, C group is the second, A group is the lowest. Pressure maintenance test shows A and C group is comparatively up to the experimental standard(<10%), B group is comparatively below the experimental standard(<10%). Conclusions : Results show stability of cups and air pumps is suitable for medical instruments. And negative pressure of cupping and maintenance of pressure show various results. So it is necessary to set up a standard negative pressure of cupping and maintenance of pressure.

A model for teaching traditional Korean rhythmic patterns using Orff's ear training approach was developed and implemented with aim that it could be used as basic data for the operation of Korean music education. Children's rhythmic sense improved through teaching of sound searching, body rhythm, playing instruments, and improvising. Teaching the order of connective rhythmic patterns and a basic patterns-centered approach was more effective than teaching modified rhythmic patterns. With ear training, children perceived the stress of rhythmic patterns in advance and they perceived the length of sound. These results show that this model can be used as a basic approach in the operation of Korean music education.

In current endodontic practice, introduction of operating microscope, ultrasonic instruments, and microinstruments has induced a big change in the field of surgical retreatment. In this study, we aimed to offer key steps of endodontic microsurgery procedure compared with traditional root-end surgery, and to evaluate factors influencing success and failure based on published articles. Endodontic microsurgery is a surgical procedure performed with the aid of a microscope, ultrasonic instruments and modern microsurgical instruments. The microscope provides magnification and illumination - essential for identifying minute details of the apical anatomy. Ultrasonic instruments facilitate the precise root-end preparation that is within the anatomical space of the canal. Modern endodontics can therefore be performed with precision and predictability, thus eliminating the disadvantages inherent in traditional periapical surgery such as large osteotomy, beveled apicoectomy, inaccurate root-end preparation and the inability to observe isthmus. Factors influencing the outcomes of endodontic microsurgery may be diverse, but standardization of procedures can minimize its range. Among patient and tooth-related factors, periodontal status and tooth position are known to be prognostic, but there are only few articles concerning this matter. High-evidence randomized clinical trials or prospective cohort studies are needed to confirm these findings.
