Dentigerous cyst is one of the most prevalent types of odontogenic cysts in the jaw. Usually dentigerous cysts begin to develope through an accumulation of fluid between remnants of the enamel organ and subjacent tooth crown which is developing or submerged. The teeth most often involved are mandibular third molars, maxillary canines, and mandibular premolars. And the cysts usually occur in the second or third decade of life. The treatment of dentigerous cysts-enucleation, marsupialization, and fenestration-is dictated by the size, environmental structures of the lesion, and desirability of conserving involved tooth. Marsupialization is a conservative technique which allows the reduction or elimination of cystic lesion by making it an accessory compartment of the oral cavity in the case where complete enucleation is not desirable. Marsupialization is thought to be the most suitable method of treatment for the conserving of the involved tooth, thus guiding eruption of it. We report the positive outcome got from marsupialization in dentigerous cysts with review of literature.
The purpose of this study is to figure out how stage costume of Peking Opera communicates what the character wants to inform to spectator. The stage costume means the clothing, shoes, headdress, accessory that the cast is worn for communicating personality of character. Stage costume not only reveals the character of new spirit who the director and the work is like to create, but also makes the style of play harmonizing with the atmosphere of the work. So, the stage costume in the play is a sort of symbol system that forms the depth of play. The stage costume of Peking Opera was formed on the basis of the Chinese traditional stage costume in the Qing period, however the style of stage costume was beautified the costume of Ming period and here contained the factors of successive costumes. But the stage costume of Peking Opera don't have the same rank system with real history costume and don't have demarcation according to period and history. Only it is that transformed and created the real history costume with Chinese fine view and made how they wear Chinese fine view and made how they wear the costume according to position, age, personality of character in the play. In the stage costume of Peking Opera, the color is cultural language that director can communicate to spectators and can inform spectator of sex, age, personality, position of the character. The color of the stage costume of Peking Opera reflects the principles of Yin and Yang and the five elements of the Chinese cosmogony. The pattern of decoration also makes the personality and characteristic of the character. The dragon pattern symbols the authority and majesty, so only the character of high position can use it. The pattern of tiger and leopard symbols bravery, so the military officer can use it. Civil officer decorates with the pattern of Japanese apricot, orchid, chrysanthmum, bamboo that symbols integrity and honor. The stage costume of Peking Opera communicates the identity of character with the special form of costume. Kanjien is a costume of the young priestess, Houyi is the Sunwukong'costume. Chayi is a costume of boatman. Lingzi, Sweixiu, Kaoqi is the props for the foramtive effect of stage costume, also they play an important part in expressing the emotion situation. In the result of study, we could know that the form, color, pattern of the stage costume and props of Peking Opera play important parts in communicating informations that let spectator can understand the play. So, the stage costume of Peking Opera is an‘picturizing costume’that the form, color, pattern of the stage costume is a sort of symbol system. It makes spectator feels actually the viewing Peking Opera.

A method of dynamic analysis is developed for torsional free vibrations of elliptical-box girder type or stiffening truss system suspension bridge. In this study, the method based on a finite element technique using a digital computer, is illustrated by two numerical examples, the Namhae Bridge which is located in Kyungsang nam-do opened on June, 1973, and the Mt. Chunma Bridge is simple span pedestrian's suspension bridge with lateral bracing system in Mt. Chunma, Kyungki-do, are used. In general, dynamic modes of complex suspension bridges are three-dimensional in form, i.e., coupling between vertical and torsional motions. However, introduced that amplitudes of oscillation are infinitesimal for coincidence with the purpose of it's use, thereupon, the torsional vibration analyses are treated without coupling terms. A sufficient number of natural frequencies and mode shapes for torsional free vibration are presented in this paper. In the case of Mt. Chunma Bridge, the natural frequencies and periods are computed with and without reinforcement, respectively, and compared their discrepancies. The influence of the auxiliary reinforcing cables is prevailing in the first few modes, namely, 1st and 2nd in symmetric and 1st, 2nd and 3rd in antisymmetric vibration, and conspicuous in the symmetric compared with the antisymmetric motion, but in the higher modes, this kind of simple accessory elucidates rether converse effects. In the Namhae Bridge, the results are compared with the Manual's obtained by wind tunnel test. It reveals commendable agreement.
On the basis of the semen analysis in 66 subjects, they were divided into six different groups: Group I consisted of 16 normal subjects with sperm counts of over 40 ${\times}10^6$/ml and motility of over 40 percent, Group II, 7 subjects with normal sperm counts, but motility of under 40 percent, Group III, 15 oligospermic patients with under 40 ${\times}10^6$/ml, Group IV 14 azoospermic patients, Group V, 10 patients with vasectomy and Group VI, 4 abnormal patients with 2 cases of hypoplastic testis, 1 case of Klinefelter's syndrome and 1 case of testis tumor. After seperation of semen into sperm and seminal plasma by centrifugation, the protein contents and the activities of hyaluronidase, ${\beta}$-N acetylglucosaminidase, ${\beta}$-glucuronidase, arylsulfatase, acrosin and azocoll proteinase in seminal plasma were measured. Vasectomy group has 30 percent less of total protein than normal group. For the comparison of enzyme activities of seminal plasma, it could be assumed that the enzymes in seminal plasma were not contaminated with the enzymes of spermatozoa by testing the enzymes of the seminal plasma from the vasectomy and azoospermic groups. It had been reported that hyaluronidase was only released from spermatozoa, however, the result obtained in this investigation showed that azoospermic and vasectomy group had high specific activities of hyaluronidase. The results indicated that hyaluronidase was not only from the testis but also from the male accessory sexual glands. Oligospermic group (Group III) showed the lowest total activity of hyaluronidase among them. The specific activities of ${\beta}$ -N-acetylglucosaminidase was high in oligospermic group (Group III) and low in vasectomy group (Group V). These results were contradictory with the pattern of hyaluronidase activities. This indicated that the spermatozoa which were stayed in epididymis would increase the activity of this enzyme. The specific activity of ${\beta}$ - glucuronidase was low in oligospermic and vasectomy groups. Group VI including testis tumor had remarkably high arylsulfatase activity. Arylsulfatase, a typical lysosomal enzyme, has been known to be released unusually large amounts from certain tumor cells. Arylsulfatase was also released with high activities from azoospermic and vascetomy group. This result indicated that this enzyme was also released from the sources other than testis. Acrosin, a proteolytic enzyme locating in the sperm acrosome, was not found throughout all the samples of seminal plasma. The activities of azocoll proteinase, a non-specific neutral proteinase was nearly identical in all the groups. This enzyme must have been released from the sources other than testis.

The present study was undertaken to evaluate the prevalence rate of Taenia species infection and distribution of taeniasis caused by Taenia solium among Koreans in Seoul and Cheju Do In Korea during the period from August to December 1984. A total of 4,256 stool specimens from the students of Mapo Ku and 360 stool specimens from the inhabitants of Guro-Ku in Seoul was collected and examined by cellophane thick smear technique. On the other hand 1,015 stool specimens from the students of Jocheon Myun and 265 specimens from the students of Jocheon Myun and 265 specimens from the inhabitants of Aeweol Myun and Gujwa Myun in Cheju Do were also examined. The results were summarized as follows ; Four (0.1%) out of 4.256 students were positive and 2 (0.6%) out of 360 inhabitants in Seoul were positive (Table 1, 2). Positive rates of taeniasis in Cheju Do were 1.7% (17) out of 1,015 students and 12.5% (33) out of 5 villagers (Table 3, 4). In order to observe the distribution of Taenia solium infection, the scolex or a part of Taenia spp. were collected from the stool of positive cases by anthelmintic treatment. For the species identification, expelled proglottides were examined microscopically by the number of branches of the uterus, presence of vaginal sphincter or the accessory ovarian lobe etc. Three cases were infected with Taenia solium among 6 egg positive cases in Seoul. But only 1 case was infected with Taenia solium out of 7 students taking anthelmintics voluntarily by recommendation of Korean Association for Parasite Eradication (KAFPE). On the other hand, among 32 cases of egg positive cases of this study and 26 cases of KAFPE in Cheju Do, 13 cases (22.4%) were infected with Taenia solium. But 13 cases who were not examined and complained expulsion of proglottides in their stool were infected with Taenia saginata (Table 5). Among 62 persons infected with Taenia saginata, only 4 cases did not know their infection of this worm. Rut in 17 cases with Taenia solium, 7 persons did not know their infection until stool examinations were performed (Table 6).
In this paper, we designed a LBS-based smart platform for Lifelog service that can utilize the other's lifelog information. The conventional Lifelog service means that the system records the daily activities of the smart device user so the user can retrieve the early-recorded information later. The proposed Lifelog service platform uses the GPS/UFID location information and the various information extracted from the image as the lifelog data. Further, the proposed Lifelog platform using DB can provide the user with the Lifelog data recorded by the other service user. The system usually provide the other's Lifelog data within the 500m distance from the user and the range of distance can be adjustable. The proposed smart platform based on image recognition for Lifelog can acquire the image from the smart device directly and perform the various image recognition processing to produce the useful image attributes. And it can store the location information, image data, image attributes and the relevant web informations on the database that can be retrieved by the other use's request. The attributes stored and managed in the image information database consist of the followings: Object ID, the image type, the capture time and the image GPS coordinates. The image type attribute has the following values: the mountain, the sea, the street, the front of building, the inside of building and the portrait. The captured image can be classified into the above image type by the pattern matching image processing techniques and the user's direct selection as well. In case of the portrait-attribute, we can choose the multiple sub-attribute values from the shirt, pant, dress and accessory sub-attributes. Managing the Lifelog data in the database, the system can provide the user with the useful additional services like a path finding to the location of the other service user's Lifelog data and information.
Background: The benefit of superior vena cava (SVC) resection in thoracic malignancies remains controversial. We analyzed the results of extended resection in patients with thoracic malignancy involving the SVC. Material and Method: From March 2000 to March 2009, we performed surgical resection and reconstruction in 18 thoracic malignancies involving the SVC. Ten male and 8 female enrolled and their mean age was 56 years. Result: SVC reconstruction was performed in 9 patients with polytetrafluoroethylene (PTFE) graft. Primary closure was possible in 6 patients by partially clamping the SVC. Patch angioplasty was performed in 3 patients with PTFE or autologous pericardial patch. Three-year survival was 58.0% and median survival time was 24.5 months. Disease specific survival and recurrence free survival were not significantly different between lung cancer and mediastinal malignancy. Obstruction of graft was detected in 4 patients during follow-up; SVC graft obstruction in 1 patient, and accessory graft between the innominate vein and right atrium in 3 patients. Conclusion: Extended resection of thoracic malignancies involving the SVC was a feasible method in selected patients. Although the morbidity rate was relatively high, mid-term survival was acceptable when complete resection was possible.
Heparin binding proteins (HBPs) are produced by accessory glands. These are secreted into the seminal fluid, bind to the spermatozoa at the time of ejaculation, favour capacitation, acrosome reaction, and alter the immune system response toward the sperm. The present study was conducted with an objective to assess the effect of purified seminal plasma-HBPs (SP-HBPs) on cross bred cattle bull sperm attributes during two phases of cryopreservation: Pre freezing and freezing-thawing. SP-HBPs were purified from pooled seminal plasma by heparin affinity chromatography. Three doses of SP-HBPs i.e. 10, 20, $40{\mu}g/mLs$ semen were standardized to find out the optimum dose and $20{\mu}g/mLs$ was found to be an optimum dose. Semen as such and treated with SP-HBPs was diluted with sodium citrate-egg yolk diluter and cryopreserved as per the standard protocol. Sperm parameters i.e. motility, viability, Hypo-osmotic swelling test (HOST), acrosome damage, in vitro capacitation and lipid peroxidation were evaluated in SP-HBP treated and untreated (control) semen at both phases of cryopreservation. A considerable variation in percent sperm motility, viability, membrane integrity (HOST), acrosome damage, acrosome reaction and lipid peroxidation was observed at both phases among the bulls irrespective of the treatment. Incubation of neat semen with $20{\mu}g/mL$ SP-HBP before processing for cryopreservation enhanced the average motility, viability, membrane integrity by 7.2%, 1.5%, 7.9%, and 5.6%, 6.6%, 7.4% in pre-frozen and frozen-thawed semen in comparison to control. There was also an average increase of 4.1%/3.9% in in vitro capacitation and acrosome reaction in SP-HBPs-treated frozen-thawed semen as compared to control. However, binding of SP-HBPs to the sperm declined acrosome damage and lipid peroxidation by 1.3%/4.1% and 22.1/$32.7{\mu}M$/$10^9$ spermatozoa in SP-HBP treated pre-frozen/frozen-thawed semen as compared to control, respectively. Significant (p<0.05) effects were observed only in motility, HOST and in vitro acrosome reaction. It can be concluded that treatment of neat semen with SP-HBPs before cryopreservation minimized the cryoinjury by decreasing the generation of reactive oxygen species.
Purpose: This study was performed to investigate the incidence and configuration of the bifid mandibular canal in a Korean population by using cone-beam computed tomography (CBCT) imaging. Materials and Methods: CBCT images of 1933 patients (884 male and 1049 female) were evaluated using PSR-9000N and Alphard-Vega 3030 Dental CT units (Asahi Roentgen Ind. Co., Ltd, Kyoto, Japan). Image analysis was performed by using OnDemand3D software (CyberMed Inc., Seoul, Korea). The bifid mandibular canal was identified and classified into four types, namely, the forward canal, buccolingual canal, dental canal, and retromolar canal. Statistical analysis was performed by using the chi-squared test and one-way analysis of variance (ANOVA). Results: Bifid mandibular canals were observed in 198 (10.2%) of 1933 patients. The most frequently observed type of bifid mandibular canal was the retromolar canal (n=104, rate: 52.5%) without any significant difference among the incidence of each age and gender. The mean diameter of the accessory canal was 1.27 mm (range: 0.27-3.29 mm) without any significant difference among the mean diameter of each type of the bifid mandibular canal. The mean length of the bifid mandibular canals was 14.97mm(range: 2.17-38.8 mm) with only a significant difference between the dental canal and the other types. Conclusion: The bifid mandibular canal is not uncommon in Koreans and has a prevalence of 10.2% as indicated in the present study. It is suggested that a CBCT examination be recommended for detecting a bifid canal.

This study aimed to investigate the sociocultural phenomena which affected to clothing change in 1650-1900 and to examine the features of men's necktie in the western art. For this study, information about historic neckwear is obtained from the visual evidence of painted or engraved portraits, contemporary written sources. The covered area of this study was Europe mainly England and France. For this process, research steps were as follows : 1. Investigating the sociocultural phenomena which affect to clothing change through 1650-1900 and analysis of men's clothing and appearance. 2. Finding the changing characteristics of neckties including it's different types, shapes, knots, colors and materials and analyzing similarities and differences of neckties by the times. 3. Examining necktie as one of important and representative icons of male gender identity. The results of the study was as follows: 1. In 1660-1900, men's fashion was simplified in color and detail due to the influence of practical Puritanism and matured civil culture. And British men's fashion spreaded throughout whole European countries and get popularity. 2. In 1650-1720, there were band, cravat and steinkirk. And expecially cravatier, a expert custodian of cravats, was appeared in that period. In 1720-1800, there were stock, solitaire and cravat. In 1800-1850, neckwear were popularized and got various sizes and types up to shape and size of chemise collars. Black stock, scarf cravat and shawl cravat were popular and terms of 'necktie' were used for an certain neckcloth shape. And abundant literature for necktie were published thanks to the development of printing technology in that period. In 1851-1900, the leady-made neckties were spreaded and there were changes in shape, length, knot of necktie up to V-zone formed with shirt's collars and vest types. Neckwear was gradually evolving through four distinct styles, bow tie, scarf or neckerchief, Ascot and four-in-hand. 3. After the mid-l7th Century, as civil culture matured and splendid and extravagant colorful men's wear disappeared, British men's fashion spreaded throughout whole European countries and got popularity. The necktie become an essential ornamental accessory of men's fashion and one of important and representative icons of male gender identity.
