Objective : There are controversial opinions on the location of PC8 (Nogung). The one is to localize the point between the 2nd and 3rd metacarpal bone, the other is to localize the point between the 3rd and 4th metacarpal bone. The study was performed to provide an experimental evidence to standardize the location of PC8 point. Methods : We employed 30 healthy adults evenly in sex. To identify the location of PC8 in the hand, we took X-ray photograph in both hands of participants. Thin layer of leads were pasted on to PC7 and tip of middle finger prior to take X-ray photograph. The line connecting two points corresponding to the leads in X-ray film was read by a radiologist to decide that the line passes which side between the 2nd metacarpal space and the 3rd one. Results and Conclusions: The line passed the 3rd metacarpal space in 49 cases out of 60 hands (82 %). Data suggest that PC8 could be localized at the point between the 3rd and 4th metacarpal bone.

Background : The location of acupoints on rat, which may differ from that of human body due to anatomical structure, is defined variously among researchers, which may cause the problem of low repeatability and objectivity. Design : The measurement of hind limb consist of measuring the distance between knee joint and tibia tubercle in order to set the knee joint as common criteria. Based on it, the three mostly referred location of ST36 were represented with the knee joint as a datum point and compared. The electroacupuncture stimulation was administrated after the abdominal pain was induced by acetic acid. And the analgesic activity of each ST36 acupoint was evaluated by measuring the number of writhing reflex, in order to observe the differences of treatment effect in accordance with the location of ST36 acupoints. Results : The result of measurement confirmed the differences in the acupoint location of ST36 among researchers. The writhing reflex test using the acetic acid-induced abdominal pain stimulated with electroacupuncture of 100Hz showed that there were statistically significant differences in the analgesic effect between control group and three ST36 groups (P<0.05). However there were no differences observed among three mostly referred location of ST36 acupoints (P>0.05). Conclusions : We recommend "the point located 6.5 mm below the knee joint at the anterior tibial muscle" as a standard ST36 acupoint location qualified by the WHO Standard Acupuncture Point Locations in 2008.

Image retrieval research activity has moved its focus from global descriptors to local descriptors of feature point such as SIFT. MPEG is Currently working on standardization of effective coding of location and local descriptors of feature point in the context mobile based image search driven application in the name of MPEG-7 CDVS (Compact Descriptor for Visual Search). The extracted feature points consist of two parts, location information and Descriptor. For efficient image retrieval, we proposed a novel method that is gradual block-based efficient lossy location coding to compress location information according to distribution in images. From experimental result, the number of average bits per feature point reduce 5~6% and the accuracy rate keep compared to state of the art TM 3.0.

Geostationary ocean satellite, unlike other sun-synchronous polar-orbit satellites, will be able to take a picture of a large region several times a day (almost with every one hour interval). For geostationary satellite, the target region is fixed though the location of sun is changed always. Thus, the ocean signal of a given target point is largely dependent on time. In other words, the ocean signal detected by geostationary satellite sensor must translate to the signal of target when both sun and satellite are located in nadir, using another correction model. This correction is performed with a standardization of signal throughout relative geometric relationship among satellite - sun - target points. One signal value of a selected pixel point of the target region of Geostationary Ocean Colour Imager (GOCI) would be set up as a standard, and the ratio of all remained pixel point can be calculated. This relative ratio called bidirectional factor, the result of modelling of spatiotemporal variation of bidirectional factor is shown.

The terrestrial-DMB (T-DMB) provides one-way broadcasting service in intial phase and two-way interactive data services through a return channel of mobile communications network are commercialized recently. The possible evolution of the T-DMB will be fully convergence between the T-DMB and other communication services such as telematics, RFID and so on. From this evolution point of view, a framework should be defined for supporting telematics and RFID applications on T-BMB platform. In this paper, we propose an integrated service model that could support RFID application services on the interactive T-DMB. To realize the model, we design a service scenario, a network reference model, functionalities of each entity, a data transmission mechanism messages, and coding rules. The service model could allow users to support the identical RFID application services over the T-DMB network even if T-DMB terminal doesn't have RFID reader capability. In addition, in the case for providing the interactive TTI(Traffic and Travel Information)service, users could utilize the current location based RFID application service using by the TPEG-Location application that forms the basis of user location referencing. The messages structure is designed by following TPEG standardization

Objectives : Standardization and clear description of locating acupuncture points guarantees reproducibility and credibility of the results in animal studies of acupuncture points and meridians. In this study, we aimed at analyzing the acupoint description of the previous experimental studies and suggesting guidelines for related journals. Methods : We searched animal studies where acupuncture points were used in Journal of Korean Acupuncture & Moxibustion Society and Journal of Meridian & Acupoint with a limitation of period, from 2002 to 2006. Data on experimental animals, acupuncture points and their descriptions were extracted and put in a predefined form. They were classified as one of the 4 classes; A) descriptions of the acupuncture points present, B) no description of the acupuncture points and only reference provided, C) neither description of the acupuncture points nor reference provided, or D) acupuncture point detector used. Two authors independently extracted and classified the data and the disagreements were resolved by discussion. Experts were invited to rate acupuncture point description validity on a numeric rating scale in the 11-item questionnaire. Results : Two hundred and five studies were identified and classified as follows; A) 32.2% (n=66), B) 7.8% (n=16), C) 51.2% (n=105), and D) 8.8% (n=18). Experts ratings were significantly lower for class C (mean${\pm}$SD, 2.14${\pm}$1.35, 95% CI [1.90, 2.39], P = 0.004 compared with class B, P ${\leq}$ 0.001 compared with class A or C) and no difference was found between classes A, B, and D. Conclusions : Reporting of acupuncture points in experimental animals is poor and validity and reliability of the result from such reporting is hampered. We suggest that journal editors and experts provide guidelines for reporting animal acupuncture points and adopt them into guide for authors for related journals.

In Korea, the address-point matching technique has been used to provide geocoding services. In fact, this technique brings the high positional accuracy. However, the quality of geocoding result can be limited, since it is significantly affected by data quality. Also, it cannot be used for the 3D address geocoding and the reverse geocoding. In order to alleviate issues, the paper has implemeted proposed geocoding methods, based on street-based addresses matching technique developed by US census bureau, for street-based addresses in Korea. Those proposed geocoding methods are illustrated in two ways; (1) street address-matching method, which of being used for not only 2D addresses representing a single building but also 3D addresses representing indoor space or underground building, and (2) reverse geocoding method, whichas converting a location point to a readable address. The result of street-based address geocoding shows 82.63% match rates, while the result of reverse geocoding shows 98.5% match rates within approximately 1.7(m) the average position error. According to the results, we could conclude that the proposed geocoding techniques enable to provide the LBS(Location Based Service). To develop the geocoding methods, the study has perfoermed by ignoring the parsing algorithms for address standardization as well as the several areas with unusual addresses, such as sub-urban areas or subordinate areas to the roads, etc. In the future, we are planning the improved geocoding methods for considering these cases.

Objectives : The objective of this study is to apply the contents of "WaHyul(訛穴 : The errors of acupoint locations"of "ChimGuKyungHumBang" to modern acupoint locations. Methods : The text of "WaHyul" was closely examined and analyzed. "WHO standard acupuncture point locations in the western pacific region" was reviewed based on its contents. Results : According to the analysis, the correct 少商(LU11) was mentioned as a spot appropriately distanced from the corner of the nail root under the skin. This is the most accurate and reasonable synthesis of other related texts. Furthermore, the necessity of defining the locations of all the well points was also emphasized and their locations were mentioned that could be located by the same method. There is no further discussion of other acupoints apart from descriptions of their locations from other texts. Some parts that were pointed out as common errors included not only commonly made mistakes, but errors made in acupuncture texts as were true for 神門(HT7) and 肩井(GB21). The standards of 少商(LU11), 合谷(LI4) and 足三里(ST36) presented in the WHO Standardization are not only similar to what 「WaHyul」 indicated as errors in acupoint locations, but also deviate other acupuncture texts; appropriate corrections must be made. The standard of 肩井(GB21) presents a new acupoint locating method never mentioned before in received classic acupuncture texts and so a rediscussion is in need. Other standards, such as the 絶骨(GB39), had some points of controversy, yet somewhat incomplete while HT7 did not go beyond the bounds of "WaHyul". Conclusions : "WaHyul" can be used to revise WHO standards, and has practical value in modern acupoint locating.

Geostationary Orbit satellite, unlike other sun-synchronous polar-orbit satellites, will be able to take a picture of a large region several times a day (almost with everyone hour interval). For geostationary satellite, the target region is fixed though the location of sun is changed always. However, Sun-synchronous polar-orbit satellites able to take a picture of target region same time a everyday. Thus Ocean signal is almost same. Accordingly, the ocean signal of a given target point is largely dependent on time. In other words, the ocean signal detected by geostationary satellite sensor must translate to the signal of target when both sun and satellite are located in nadir, using another correction model. This correction is performed with a standardization of signal throughout relative geometric relationship among satellite-sun-target points. This relative ratio called bidirectional factor. To find relationship between time and $[L_w]_N$/Bidirectional Factor differences, we are calculate solar position, geometry parameters. And reflectance, total radiance at the top of atmosphere(). And water leaving radiance, normalized water leaving radiance. And calculate bidirectional factor, that is the ratio of $[L_w]_N$ between target region and aiming the point. Then, we can make the bidirectional factor lookup table for one year imaging. So, we suggested for necessary to simulation experiment bidirectional factor in more various condition(wavelength and ocean/air condition).

Book numbers can be defined as the device for providing a unique self location for each book. They should include main entry which consists of author, title, the date of publication. Now, the university libraries are using eleven different methods on book numbers, in other words, nine eastern methods and two western methods. The aim of this study is to investigate problems that the present book number system has and some concerns that should be taken into account in case of the modification of the book number system and change into a new one. This study is based on the survey in that the librarian gave to 110 university libraries throughout the nation. As a result, the survey indicates that the crucial concerns of the participathing libraries are ineffective book management and the duplication of book numbers. In addition, the survey indicates that the priorities of the libraries is removing duplicated numbers, adhering to the current system, and keeping the same book arrangement system. Therefore, this study suggests the components for the expansion of the book number system and the necessity of standardization of diverse book numbers.
