The purpose of this study was to document; the development of head circumferences, changes of the eyes, and the time of eruption of deciduous teeth in Shih-tzu dogs. In 12 pups of 4 Shih-tzu bitches, the development of head circumferences were estimated from whelping day (Day 0) to 41 days after birth, and the changes of the eyes and the time of eruption of deciduous teeth were estimated from whelping day to 45 days. The head circumferences were $11.24{\pm}0.67\;(mean{\pm}S.D)$ cm in Day 0 and $19.87{\pm}1.42cm$ in Day 41 and the daily increased length was $0.22{\pm}0.08cm$, respectively. The changes of the eyes wert: determined the first and the completely opening time of eyes. The first and completely opening time of the eyes in pups Day $10.75{\pm}0.97$ (range: $9.50{\sim}13.00$) and Day $13.17{\pm}1.27\;(11.50{\sim}15.33)$, respectively. In the time of deciduous teeth eruption in Shih-tzu, the first day of eruption was started in Day 35.90. The rank of deciduous teeth eruption was $C_1,\;C^1,\;P_3,\;I^3,\;I^2,\;P_4,\;I^1\;and\;P_2$, respectively.

Background: The aim of this study was to document the optimal spacing of two cannulae to form continuous strip lesions and maximal surface area by using water-cooled bipolar radiofrequency technology. Methods: Two water-cooled needle probes (15 cm length, 18-gauge probe with 6 mm electrode tip) were placed in a parallel position 10, 20, 24, 26, and 28 mm apart and submerged in egg white. Temperatures of the probes were raised from $35^{\circ}C$ to $90^{\circ}C$ and the progress of lesion formation was photographed every 1 minute with the increase of the tip temperature. Approximately 30 photographs were taken. The resultant surface areas of the lesions were measured with the digital image program. Results: Continuous strip lesions were formed when the cannulae were spaced 24 mm or less apart; monopolar lesions around each cannula resulted if they were spaced more than 26 mm apart. Maximal surface areas through the formation of continuous strip lesion were 221 $mm^2$, 375 $mm^2$, and 476 $mm^2$ in 10, 20, and 24 mm, respectively. Summations of maximal surface area of each monopolar lesions were 394 $mm^2$ and 103 $mm^2$ in 26 and 28 mm, respectively. Conclusions: Water-cooled bipolar Radiofrequency technology creates continuous "strip" lesions proportional in size to the distance between the probes till the distance between cannulae is 24 mm or less. Spacing the cannulae 24 mm apart and treating about $80^{\circ}C$ for 24 minutes maximizes the surface area of the lesion.

In international sales of goods, the buyer must pay the price for the goods as required by the contract and CISG, The buyer's this obligation includes taking such steps and complying with such formalities as may be required under the contract, which includes providing the seller with relevant letter of credit through the issuing bank. Where the parties have not stipulated the time limit within which the credit should be opened, but there is an agreed date or period for shipment, the time limit for the L/C opening should be calculated back from the agreed date of shipment or the first date of shipment, while, in addition, the buyer should open the L/C sufficiently earlier than the shipment date in order for the seller to be able to know the L/C's opening before beginning to ship the goods. The L/C provided the buyer should conform to the contract of sale. Therefore, for example, when an unconfirmed L/C is provided violating the agreement or the L/C opened states that, under a FOB contract, a "freght prepaid" bill of lading shall be presented as a required document of the L/C, the buyer has failed to perform his obligation. If the buyer fails to perform his obligations to provide the letter of credit, the seller may require the buyer to perform that obligation; may fix an additional period of time of reasonable length for performance of the obligation; or, the seller may declare the contract avoided, if the failure amounts to a fundamental breach of contract, or if the buyer does not, within the additional period of time fixed by the seller, perform the obligation; and the seller claim damages. However, when a relevant L/C has been issued for the seller, as a rule, he cannot ask directly for the buyer to pay the price before avail himself of the L/C first.

Even though Joseon Dynasty strictly identified between military and civil officials, the dress and its ornament have been studied only based on embroidery emblems that are correctly identified between military and civil officials. Thus, this study intends to research the features of the only military officials uniform, Cheollik, different from the civil officials's identifying them with other features shown from the records, unearthed relics, stone statue, Joseon-tongsinsa-haengnyeoldo(Illustration of Joseon Delegation to Japan), etc., and its results are as follows: First, for wearing examples of the military officials, from the facts that they had worn mainly ordinary clothes, etc. on announcement of military service examination. There was no difference between military and civil officials's clothes by Daejeonhusokrok and the other documents, and there was an assertion that the form of the military and civil officials's clothes should be different by the document, Hongjejeonseo, in the latter term of the Joseon Dynasty. It is presumed that length, width and shape of sleeves might have been different. Second, unearthed Cheollik of the military officials are mostly from the 16th~17th centuries and most of them have removable sleeves according to statistics. The skirt had an opening and one or two slits. Various textiles were used. Third, military official statues of high governor wear small caps and helmets. They wear Cheollik with the collars same as the collar of Bangryeong and Jikryeong, which is also called Dopji Cheollik. It would be considered as they wear the Bangryeong on top of the Cheollik. Fourth, militarly officials described on the Joseon-tongsinsa-haengnyeoldo(Illustration of Joseon Delegation to Japan) wear Cheollik, Rip, Donggae, Okro, Hongsadae, Hwando, Deungchae.

This study was undertaken to document relations between facial skeletal pattern and dental occlusion. The data in .this study were collected from pretreatment cephalometric radiographs and study models of patients' records present in the files of Orthodontic Department, Seoul National University Hospital. Patients were selected on the basis of a mandibular plane-sella nasion angle equal to or greater than $38^{\circ}$ (high SN-MP angle) or equal to or less than $26^{\circ}$ (low SN-MP angle). Patients in the mixed dentition and with missing permanent teeth were excluded for ease of assessing tooth size / arch circumference relationships and then 30 high SN-MP and 11 low SN-MP patients were selected among them. The mean age of these two groups of patients was high SN-MP, $12.8{\pm}1.23$ years and low SN-MP, $13.0{\pm}1.48$ years. The following conclusions were obtained. 1. In the maxilla and mandible the mean tooth size of high SN-MP patients was nearlly identical to the low SN-MP patients. 2. The mean maxillary arch circumference was increased in low SN-MP group compared with high SN-MP group and a smilar, but smaller, mean increase was present in mandible. 3. The difference between the mean maxillary circumference required and the mean maillary circumference present ranged from -4.8mm in the high SN-MP group to -1.3mm in the low SN-MP group. A small range of means occurred in the mandible (high SN-MP: -4.0mm to low SN-MP: -1.8mm). 4. In the maxilla and mandible the mean arch length was nearly identical in the high and low SN-MP groups. 5. The mean incisor inclination was increased as the SN-MP angle decreased in the maxilla and mandible. 6. The men distance of the maxillary first molar from anterior border of the pterygomaxillary fissure was nearly similar between high and low groups. 7. The mean mandibular intermolar width was increased from high SN-MP to low SN-MP patients.

In 2004. as a part of special housing policy for low income household, Korean government initiated 'Multiple-dwelling Purchase and Public Rental Program'(MDPPRP) to help people whose needs for appropriate housing cannot be met in private housing market. The main goal of this program was to provide the base for self support of tenants by purchasing 'Multiple-housing' in bundle and transferring them into rental housing with low price to the low income tenants. Unlike other public rental housing programs, this model program limited the length of stay in the rental housing by six years to lead tenant's self support. The purpose of this study was to evaluate the effectiveness of this model program for further expanding enforcement. For this, two groups of residents of 'multiple-dwelling purchase and public rental program' and permanent rental housing were compared and analyzed. Thirty two tenants of MDPPRP were interviewed for the study. As research methods, document review, onsite tenant interviews using questionnaire were used. As a whole, most of the tenants were satisfied with their 'multiple-dwelling' environment in physical and socio-psychological aspects.

Complex queries such as path alld twig patterns have been the focus of much research on processing XML data. Structural join algorithms use a form of encoded structural information for elements in an XML document to facilitate join processing. Recently, structural join algorithms such as Twigstack and TSGeneric- have been developed to process such complex queries, and they have been shown that the processing costs of the algorithms are linearly proportional to the sum of input data. However, the algorithms have a shortcoming that their processing costs increase with the length of a queery. To overcome the shortcoming, we propose the segment join technique to augment the structural join with structural indexes such as the 1-Index. The SegmentTwig algorithm based on the segment join technique performs joins between a pair of segments, which is a series of query nodes, rather than joins between a pair of query nodes. Consequently, the query can be processed by reading only a query node per segment. Our experimental study shorts that segment join algorithms outperform the structural join methods consistently and considerably for various data sets.

In this paper we realized a system, if a user selects the area of the important parts or the arrangement parts when he reads the books or the papers, which amends, stores and readjusts the characters that are included in the selected area by outputting the characters to the word processor in sequence. If a user selects what he wishes lot with his finger, the system detects the movement of the finger by applying the hand recognition algorithm and recognizes the selected area. The system converts the distance of the width and the length of the selected area to the number of the pulse, and controls the motor to move the camera at the position. After the system scales up/down the zoom to be able to recognize the character and controls the focus to the regulated zoom closely, it controls the focus in detail to get more distinct image by using the difference of the light and darkness. We realize the recognition and editing support system of korean language that converts the obtained images to the document by applying the character recognition algorithm and arrange the important parts.

As shown in Wikipedia, tagging or cross-linking through major key-words improves the readability of documents. Recently, the Semantic Web rises the importance of social tagging as a key feature of the Web 2.0 and Tag Cloud has emerged as its crucial phenotype. In this paper we provides an efficient method of automated keyword tagging based on controlled term collection, where the computational complexity of O(mN) - if pattern matching algorithm is used - can be reduced to O(mlogN) - if Information Retrieval is adopted - while m is the length of target document and N is the total number of candidate terms to be tagged. The result shows that IR-based tagging speeds up 5.6 times compared with fast pattern matching algorithm.

This document presents the JES(Joint Element Structure) method that has been adopted for the firs time in our country for the construction of the structure crossing under the railroad without open excavation. Front Jacking Method, Tubular Roof Construction Method, New Tubular Roof Method and Joint Element Structure Method are commonly used for the construction of structures crossing under the railroad. JES Method, frequently used in Japan recently, is a new method to construct the structures crossing under the railroad in a safe manner and in a relatively short period of time by utilizing the steel elements with the joints through which the load in the vertical angle to the axial direction is transferred to the next element. The elements are tied to each other through the joints to form the permanent walls of a Rahmen structure under the road without open excavation and without limitation to the length in a convenient way. Through the case study in the project of a Subway Box Culvert Improvement for the Gyeonguiseon Railroad in front of Yonsei University using the JES Method, the cost and period of construction in various types of soil is investigated compared to the Front Jacking Method. Furthermore, by analyzing the results of instrumentation measurements carried out throughout the construction, comparison between the actual displacement in the ground and the predicted displacement in the design is made to provide the considerations to be counted for the design. In conclusion, comparison in the field of economic feasibility, constructability and safety between the JES Method and Front Jacking Method, which is most frequently adopted in our country at present, is made to present the JES Method as a new alternative for the non-open excavation construction method for the structures crossing under the railway.
