In the ubiquitous computing environment, service providers should able to deliver their services to various devices, such as PDA, Smart Phone, Telematics devices. For this purpose, W3C announced 'Composite Capabilities / Preference Profile (CC/PP) Standard' for delivery-context description. At present, only a small number of mobile phone supports the CC/PP standard, But most of contents servers do not. In this paper, by analyzing request headers which are received from various ubiquitous devices, a rule-based CC/PP profiling method in ubiquitous environment is developed. Service providers can use these profiles for providing optimized services to the various devices which have different capabilities.

Web Service is a new model based on web to offer dynamic information for a user's request. Currently, the web service discovery mechanism is not efficient because it does not support automatic discovery based on the semantics or capabilities of a web service. The language for semantic web service, such as OWL-S, is being developed to express the capability of a web service semantically. Such semantics can support the more flexible discovery of web services. Web service discovery occurs when the provider's description matches to that of requester. But the matching can fail when the ontologies of service description differ from that of the requester although the requester wants that Web Service. In distributed environment service providers develope their semantic web services independently and tend to use their ontologies to describe web services. So a new approach must be required to avoid service discovery failure. In this paper, a method of annotating the query of requester and discovering semantic web services without service discovery failure is proposed.

butyl cyanoacrylate가 一般的인 縫合絲에 比해 齒 剝離搔爬術後 齒周辯膜의 治癒에 미치는 影響을 糾明하고자 5마리의 雜種犬 ( 6∼8kg )을 利用, 이들의 上下顎 左右 犬齒에 該當하는 頰側 附着齒 에 齒 剝離搔爬術을 施行하고 上記 2가지 方法을 區分하여 樂劑의 塗布 및 縫合을 施行한 後 定한 날에 實驗動物을 儀牲시켜 組織學的 檢鏡을 통해 이를 觀察하여 다음과 같이 結果를 얻었다. 組織學的 所見에서 初期에는 實驗部가 對照部에 比해 下部組織에 淨腫性 纖維素綱과 炎症細胞浸潤이 微弱하였고, 裂溝上皮細胞의 被服과 纖維性 骨膜의 形成이 迅速하였으며 纖維性 結締組織에 의한 齒周 膜과 齒面과의 癒合도 빨리 일어났다. releasing incision 部位에서도 實驗部가 炎症細胞浸潤이 보다 적었고, 肉茅組織의 形成이 迅速히 일어났으며 그 量도 적었다. 그러나 組織學的 觀察의 全 過程을 통해 3週에서는 治癒程度에 있어서 兩者間의 差異가 없었고, 4週에서도 兩者間의 治癒程道에 대한 差異를 觀察할 수 없었다. This is study was made in order to determine the histological changes associated with healing following the use of cyanoacrylates and silk sutures in canine areas where periodontal flap procedures had been carried out. In this experiment 5 adult mongrel dogs were used. The cyanoacrylate on the right side and black silk suture on the left buccal side of maxilla and mandibular canine area, were applied for the fixation of the flap after the periodontal flap surgery. On the experimental days, the experimental areas were examined clinically and sacrificed. Thereafter histological secimens were made following the useal methods and examined with light microscope. The results were as follows : In the histologic observations, the experimental areas as compared with the controls ; There was weak inflammatory cell infiltration and less edematous fibrin mesh formation at the substructure of the flap. The sulcus epithelial cell covering and formation of the fibrous periosteum was made rapidly. The union of periodontal flap and tooth surface by fibrous connective tissue was also made rapidly at the experimental areas. At the areas of the releasing incision less inflammatory cell infiltration and rapidity and small amount of granulation tissue formation were found. But through the entire procedure of the histologic observations, there was little difference in the degree of healing between the two in the 3rd week and it was also impossible to find the difference of healing between the two in the 4 th week.

This study aimed to analyze the main reasons for the extraction of permanent teeth among Koreans with oral diseases. The electronic medical record data for past 10 years was used in a target population comprising of 26,795 adults diagnosed with oral disease and scheduled to undergo permanent tooth extraction. The oral diseases were classified into periodontal disease, dental caries, impacted teeth, prosthodontic treatment, orthodontic treatment, tooth fracture, trauma, and others. The relationship between these diseases and permanent tooth extraction was analyzed. Permanent teeth were extracted due to periodontal disease (34.5%), dental caries (26.6%), and tooth impactions (22.3%). Permanent teeth were extracted as the cause of dental caries (28.6%) and periodontal disease (45.9%) from patients in 26-35 and 46-55 years of age respectively. The mandibular first molars (17.2%), mandibular second molars (16.0%), maxillary first molars (14.7%), and maxillary second molars (14.3%) were extracted due to dental caries. The incidence of periodontal disease was highest in the mandibular central incisor (72.6%; p<0.05). These findings indicated that periodontal disease was the chief cause of extraction of permanent teeth among Korean adults.

Introduction: Several capillary changes detected by finger nailfold capillaroscopy have been shown to correlate with microvascular complications in type 1 diabetes. However, there are few reports on the relationship between nailfold capillary abnormalities and microvascular complications in type 2 diabetes (T2DM). Herein, we investigated whether nailfold capillary microscopic changes are associated with diabetic nephropathy in patients with T2DM. Methods: We conducted a cross-sectional study in patients with T2DM diagnosed within 20 years (duration of diabetes: 6.4±6.0 years). The nailfold capillaroscopy can visualize the capillary network in fingers and is a non-invasive test. The presence of morphological abnormalities, including avascular areas, giant capillaries, dilated, tortuous, or ramified capillaries, hemorrhages and capillary architectural derangements, in finger nailfold capillaroscopy image was assessed by a single rheumatology specialist. The severity of nailfold capillary change (0 : no change, 1 : capillary change/mm <33%, 2 : capillary change/mm between 33-66%, 3 : capillary change/mm >66%) was scored. Statistical analyses were performed using Pearson correlation or Spearman rank correlation as appropriate Results: A total of 63 patients with T2DM were enrolled. Both capillary architectural derangements and avascular areas in nailfold capillaroscopy showed significant correlations with albuminuria measured by spot urine or 24-hour urine collection after adjusting for sex, age, body mass index, duration of diabetes, hemoglobin, and HbA1C. Moreover, architectural derangements and avascular areas in nailfold capillaries were significantly associated with urinary albumin excretion rate in T2DM patients diagnosed within 10 years. Conclusions: These findings have shown that nailfold capillary abnormalities are independently associated with albuminuria in patients with T2DM of moderate duration, suggesting a role of capillary changes in the pathogenesis of diabetic nephropthy.

Background/Aims: Human adenovirus type 55 (HAdV-55), an emerging epidemic strain, has caused several large outbreaks in the Korean military since 2014, and HAdV-associated acute respiratory illness (HAdV-ARI) has been continuously reported thereafter. Methods: To evaluate the epidemiologic characteristics of HAdV-ARI in the Korean military, we analyzed respiratory virus polymerase chain reaction (RV-PCR) results, pneumonia surveillance results, and severe HAdV cases from all 14 Korean military hospitals from January 2013 to May 2018 and compared these data with nationwide RV surveillance data for the civilian population. Results: A total of 14,630 RV-PCRs was performed at military hospitals. HAdV (45.4%) was the most frequently detected RV, followed by human rhinovirus (12.3%) and influenza virus (6.3%). The percentage of the military positive for HAdV was significantly greater than the percentage of civilians positive for HAdV throughout the study period, with a large outbreak occurring during the winter to spring of 2014 to 2015. The outbreak continued until the end of the study, and non-seasonal detections increased over time. The reported number of pneumonia patients also increased during the outbreak. Case fatality rate was 0.075% overall but 15.6% in patients with respiratory failure. The proportion of severe patients did not change significantly during the study period. Conclusions: A large HAdV outbreak is currently ongoing in the Korean military, with a trend away from seasonality, and HAdV-55 is likely the predominant strain. Persistent efforts to control the outbreak, HAdV type-specific surveillance, and vaccine development are required.
