The tracing system means that the system can follows, traces, and records every steps of production and delivery of goods and its ingredient. Specially, Koreans have big concern about food tracing system which is influential for health directly. We were more interested in medical herb using in oriental medicine than any other things. We proposed the process and design of tracing system for medical herb based on RFID(Radio Frequency IDentification) technology in this research. This study shows current medical herb tracing ways and RFID code system by using for world standard. Firstly, We designed the new process of traceability of medical herb with various preceding references based on RFID technology. Secondly we suggest that RFID code configuration using the international standard code(ISO code) and korean agricultural and marine products code for the proposed process. RFID code system is very important because this plays a means of identification for tracing about medical herb. The proposed code system have the elements as Issuing Agency Code, Issuer Number, inspection information, inheritance flag, area code, modified agricultural and marine products code, serial number in 96 Bit length. Lastly We defined the code-generation process in the tracing system.

In this study, based on the analysis of FRBRoo, we tried to propose suggestions to expand and improve the FRBR family conceptual model. FRBRoo is a plug-in ontology of CIDOC CRM with cooperation of museum field. As FRBR family models also revised and integrated into IFLA Library Reference Model, the additional analysis on IFLA LRM was performed. If bibliographic information is required to support the technical and user services of the library, the way to analyze the bibliographic information should be improved in order to cope with the new challenges faced by the library. To do this, time-related event concepts should be reflected in the modeling of bibliographic information. It is also necessary to expand the creation and exchange unit of bibliographic information to smaller units or larger units than legacy bibliographic records. Using FRBRoo as a linkage tool for the sharing of bibliographic information is also suggested.

Background and Objectives : Traditionally, the excision of submandibular gland (SMG) has been commonly used for treatment of calculi in the proximal duct or gland parenchyma. Over the last 10 years several new minimally invasive techniques including lithotripsy, sialendoscope were introduced in the treatment of sialolithiasis. But these have some limitation on large, infected calculi. The aim of this study is to assess the intraoral treatment of submadibular stones. Subjects and Method : The records of one hundred and seventy-three patients who underwent intraoral removal of submadibular sialolithiasis between June 1, 1989 and July 31, 2006 were retrospectively reviewed. Results : Stone location was distal to the edge of the mylohyoid muscle in 127 patients and proximal to gland in 48 patients (mean size of sialoliths, 7.1mm [range 3.0-25mm]). The complete removal of stones was observed in 170 (97.1%) patients regardless of size and location. Recurrence of lithiasis was found in 8 patients (then treated with intraoral removal in 5 patientsand resection of SMG (submandibular glands) in 3 patients). Acalculous sialadenitis in 9 patients (5.1%) and cyst formation in 2 patients (1.1%) was found. But no evidence of postoperative complications including hemorrhage, fistula, damage to lingual nerve were found. Conclusion : The intraoral removal of submandibular stone is useful in preservation of submandiblar function and effective in palpable stones regardless of location, size.

Domain Name System(DNS), one of the most important Internet services, handles mapping from host names to Internet addresses and vice versa, and precedes many Internet applications such as Web, e-mail, file transfer, etc. In this paper, we propose a structural design of a generic name server system providing name services for a huge domain for the purpose of improving the performance as well as the reliability of the system. We demonstrate the validity of the design by implementing and running a testbed system. Our testbed employs a couple of master name sowers for distributing the service overhead over two, rather than one, servers and for achieving high availability of the system as a whole. We suggest the use of dynamic update to add and delete records from a zone for which the name server has authority. The slave name servers located remotely then get a new, updated copy of the zone via incremental zone transfers(IXFRs). The experiments with the implemented testbed show that the proposed structure would easily manage increasing demands on the server power, and be highly available in the face of transient faults of a module in the system.

This study is an exploratory case study of a humanity community building process in a rural area context, particularly in the villages of Eoro-ri, Chilgok-gun, and Gyeongsangbuk-do. Chilgok-Gun has institutionalized support systems for a humanity community building, and has implemented some programs for four years. This article uses a qualitative approach to analyze the process of community buildings, such as in-depth interviews and observations. The analysis is based on the process of discovering, vitalization, and self-governing for community buildings, and give some implications for future community buildings in a rural area context as follows. First, the village leader constantly needs to be cultivated. The village leader is not a simple representative of the village. He constantly needs to make efforts to communicate with the villagers. Second, learning through constant self-reflection is necessary for the villagers. It is important to make community programs and residents' small meetings to facilitate reflection. In community buildings, the process of communication and consultation for villagers is more important. The process that creates a new value of the village in the learning process takes place. Third, talented village people who can develop the village should be educated. This is a virtuous circle for Village Development. Aging in rural areas has been deepening, which will affect the future of local communities that can meet in accordance with various crises and responses. There is a need for complex research on sustainable ways to reinvent itself as a community.

The fatality of rollover accidents in motor vehicle crashes is high despite their low incidence. Through the investigation of a 12-passenger van rollover accident in which 10 passengers were involved, we intend to analyze the correlation between the severity of the injury and the position of the occupants. We collected accident information from medical records, interviews, photo-images of the damaged van, field surveys, and the results of the Korean New Car Assessment Program (KNCAP). Based on the occupants' position, we classified injury sites and estimated injury severity. Passenger injury severity was evaluated by trauma score calculation. The initiation type of the rollover accident was passenger side 'fall-over' and the Collision Deformation Classification (CDC) code for the damaged van was 00TDZO3. The crash of the van involved 10 passengers, with an average age of $16.3{\pm}4.2years$. Few of the occupants had fastened seat belts at the time of the incident, and there was no airbag installed. One patient sustained severe liver injury and another was diagnosed with a fracture of the right humerus. The most common injuries were at the upper extremities and the neck. The average of Injury Severity Score (ISS) was $4.8{\pm}5.9$, and the average ISS of right-seated, mid-seated and left-seated occupants was $7.5{\pm}9.3$, $1.5{\pm}0.7$, and $3.3{\pm}2.1$ respectively (p>0.05). In the rollover (to-passenger side) accident of occupant unfastened, the average ISS of right-seated occupants (near side) was higher, but there was no statistically significant difference.

Upo Wetland is the largest riverine wetland in Korea which has been inscribed on the Ramsar List of Wetlands of International Importance in 1998. In this study, sedimentological study was carried out in order to understand the environmental changes in Upo Wetland during the Holocene. The drilling work for recovering the Quaternary sediments was conducted on the inner part (UPW17-01, UPW17-02, and UPW17-03) and the outer part (UPL17-01, UPL17-02) of the Upo Wetland. The recovered sediments are commonly characterized by gravel-dominated deposits in the lower part and silty clay-dominated deposits in the middle to upper parts respectively, which are seemed to be changed from fluvial to palustrine/lacustrine environments around 4,000 cal yr BP. In order to establish the Holocene diatoms distribution from Upo Wetland, we identified 63 diatom taxa. Of these, 14 species were new records for Korea: Gomphonema consector, Gomphonema jadwigiae, Hantzschia abundans, Luticola pseudomurrayi, Luticola spauldingiae, Neidium suboblongum, Ninastrelnikovia gibbosa, Oricymba rhynchocephala, Pinnularia borealis var. lanceolata, Pinnularia latarea, Pinnularia paliobducta, Pinnularia saprophila, Sellaphora laevissima, Stauroneis pseudoschimanskii. All identified diatom species are illustrated by high-quality scanning electron microscopic and light microscopic microphotographs. The ecological habitat for all taxa are presented.

Purpose: The purpose of the study was to analyze the nursing activities related to continuous renal replacement therapy (CRRT) in the intensive care units (ICU). Methods: We developed a list of 31 CRRT related nursing activities based on literature review and reviewed by expert group. A total of 109 direct time measurement records by 43 ICU nurses were collected and analyzed in terms of total time per shift, frequency, standard time, difficulty and performance levels of each CRRT nursing activity. Results: The mean time for CRRT nursing activity was 85.60 minutes per 8 hour shift. Nurses have spent average $9.46{\pm}6.98$ minutes in a shift for "waste fluid bag change" activity. In addition, "check catheter location" was the most time consuming single activity. The most difficult activity was "counseling-answer" and the most competent one was "dialysis solutions change". Conclusion: The CRRT nursing activities accounted for a significant portion of total nursing workload. Practical allocation of nursing staff for CRRT patient along with development of a new nursing cost system need to be considered. Continuous nursing educational and training programs on CRRT should be developed.

This study is about the history of costumes depicted on the book Goryosa(高麗史) Ye-Ji(禮志). Researches about the costumes of Goryo dynasty are very rare and are mostly based on Goryodogyung(高麗圖經) and Goryosa Yebok-Ji(與服志). However, records about suitable costumes for a special scene of a rite can also be found in Ye-Ji besides Yebok-Ji. Therefore, this study analyzes Ye-Ji and categorizes the results into character and situation. Characters that can be found are king, officials, crown prince, aristocrat, commoner and envoy. Situations that can be found, according to the original text, are Gilrye(吉禮), Hyoongrye(凶禮), Goonrye(軍禮) and Garye(嘉禮). The results of the study are as follows; $\blacktriangleright$ The king had to change clothes in order to suit the situation according to the precise sequence of rituals. Therefore the king had to wear different clothes in the same rite, optionally, depending on the situation. This also applies to the case of officials. $\blacktriangleright$ The crown prince and aristocrats generally wore the same clothes as officials. $\blacktriangleright$ In the important ritual of Garye(嘉禮), many cases can be found where officials wore Jobok(朝服) and hands-on worker wore Gongbok(公服). $\blacktriangleright$ It is remarkable that on the New Year's day, the winter solstice and Sungsoojul(聖壽節; the emperor's birthday) the envoy of Ming Sangbok(常服); whereas the king and the officials of Goryo wore the Myunbok(冕服) or Jobok(朝服).

Few reports have been written regarding the measurement of stern trawler warp tension under conditions of a full catch. This report compares the tension imposed on the warps at the time the boat begins to tow the net and the tension at the time the cod end is filled with a large quantity of fish. The structure of the otter boards and trawl net used for the experiment was the same types as used by Koyama, Sakurai, and Sumikawa (1968). The warp tension was measured with a load cell tension meter. 3) This meter continuously records the tension on a pen oscillograph. The net towing speed was measured with the CM-lA type current meter, Toho Dentan Co. Ltd., Japan. The data collected in the experiment are shown in Table 1. This table indicates that shooting No. 2 and No. 11 show a large catch volume, and the types of fish caught are shown in Table 2. The tension meter recordings when the boat began to tow the net and when the cod end was filled with a large quantity are shown in Fig. 1 and Fig. 2. It is indicated that the barracouta Thyrsites atun (EUPHRASEN) causes little tension difference between the time before they enter the net and the time after they enter the net before hauling. Other types of fish influence tension similarly. According to these results, the warp tension measurements as recorded on a big stern trawler are more influenced by rough sea wave action than by the volume of fish caught.
