Many researches and projects are implemented about u-IT according to changes of ubiquitous environments in the world. Especially, there are benefits to raise lifestyle and we can develop industry by applying ubiquitous regionally. Also it makes citizen feel comfortable directly. There are many projects to regionally adopt ubiquitous services like u-City model for getting this advantages. RFID technology must be suited to each environment because each RFID tag has different characteristics according to frequency band. We need to integrate bands of RFID to overcome limitations and provide more detail information and services. In this study, we develop the dual band RFID Manager needed adopting u-Zone service for both 13.56MHz and 2.45GHz. The RFID Manager, application software for base station of u-Zone, delivers the information from readers to integrated u-Zone server system.

Cleft lip is one of the most common congenital deformities in craniofacial region. Despite the many reports on the outcome of various surgical techniques from individual medical centers, the evaluation of the outcome is based on the subjective observation because of lack of the objective evaluation system. Therefore, a new technique of objective and scientific evaluation for the nasal deformity of secondary cleft lip and nose deformity is critical to improve the management of the cleft patients including the decision of optimal age of operation and surgical technique as veil as evaluation of the outcome. In this study, a new method was proposed to evaluate the nasal deformity using nostril angle, distance, and area of patient images. The images were also evaluated by three expert plastic surgeons, and put into scale of 5 percentile. Measurement results were compared between the each category and the surgeon's evaluation, and coefficients of each category were statistically tested. As a result, The normalized overlap area of right and left nostrils and distance ratio between two centers of nostrils showed high coefficient with evaluations of plastic surgeons.

Oblique facial cleft is extremely rare. The frequency was reported 1/1300 cases of facial cleft. The cleft appears to be bilateral in approximately 20% and more often on the right when unilateral. Oblique facial cleft is nearly always associated with cleft lip and palate. Thus, the case that is unilateral on the left and not associated with cleft lip or palate is very rare. We experienced a case of 2 years 6 months old Philippine girl who had oblique facial cleft that is not associated with cleft lip or palate. The probable cause and treatment is discussed with a review of literatures.

The purpose of this study is to investigate the relationship between occurrence and inducing factors of herpes labialis developed after periodontal therapy and to suggest prediction model of this lesion. A total of 100 patients were studied. A standard schedule was used for interviews of patients. It included demographic information, patient and familial history of recurrent aphthous ulcer and recurrent herpes labialis, history of systemic disease, religion, and emotional state. In case of female patients, the association of dysmenorrhea and onset of recurrent herpes labialis was also observed. After periodontal therapy, some details about therapy, such as the kind of therapy, location, spending time were recorded. At next appointment, the appearance and location of herpes labialis were examined. The frequency of herpes labialis after periodontal therapy was 8% and the location was predominantly mouth angle. The significant relationship was found between the onset of herpes labialis and the history of recurrent herpes labialis, surgical therapy rather than non-surgical therapy, and spending time. The prediction model of herpes labialis was not apparently established with the results of this study. In conclusion it is suggested that we should minimize traumatic manipulation and treatment time to prevent the onset of herpes labialis after periodontal therapy.

구강과 구인두에서 발생되는 유표피암은 전체 예수병원 암환자의 3.9%를 차지한다. 만 20 년 간의 월발성 유표피암 환자 5%명에 대한 고찰결과, 혀 전방 2/3 에서 29%로써 가장 높은 발생빈도를 보였으며 faucial arch, base of tongue 및 tonsil을 포함한 구 인두는 28%의 발생빈도를 나타냈다. 그외는 잇몸, 구강저, 구순, 구개 (palate) 및 구강내 점막의 빈도순이었다. 환자 중 153 명 만이 근치적 치료를 받았다. 1974 년 이전에는 치료 정책에 수술만이 활용되었던 까닭으로 역행성 분석결과 74 명에서는 수술만 시행케 되었으나, 그 이후의 70 명에서는 종합적치료를 시행하였으며 그중 9 명은 확실한 방사선요법을 받았다. COMMANDO 수술과 복합절제술 (Composite resection) 을 시행했던 환자들의 비교검토는 매우 의의가 있었다. 수술만 받은 환자와 비교해 볼때, 수술후 방사선요법을 병행했던 수술환자의 경우에 있어서 재발율은, Stage III 에서는 50%에서 41%로, Stage IV 는 79%에서 68%로 각각 감소를 보였다. 또한, COMMANDO 수술 경우만 국한시켜 비교할 때는 수술만 받은 환자와 비교할 때 수술후 방사선치료를 받은 환자와 비교하여 2 년간 무병율 (disease free interval) 이 수술후 방사선요법을 병행함으로써 17.3%에서 29.3%로 증가됨을 알 수 있었다.

Cleft lip is a congenital deformity condition with separation of the two sides of the lip and results in nose deformity. Evaluation of surgical corrections and outcome assessments in nose deformity resulting from the cleft lip depend mainly on doctor's objective judgment. Development of an objective assessment tool in evaluation of the condition and surgical outcome of cleft lip nose deformity patients will help in advancement and evaluation of surgical techniques of cleft lip. Hence, our study aimed on quantitative assessment of a cleft lip nose deformity condition by comparing following parameters gathered from a photographic image of a cleft lip patient: (1) angle difference between two nostril axis, (2) center of the nostril and distance between two centers, (3) overlapped area of two nostrils and (4) the overlapped area ratio of two nostrils. Assessment results of the nose deformity were determined by statistical analysis of evaluation results from three greatly experienced plastic surgeons. In addition, regression model was developed using correlation relationship and factor analysis of parameters from results of the image analysis.

A cephalometric study was undertaken to reveal significant differences of craniofacial morphology of operated congenital cleft lip and palate subjects and control subjects. The material for this study consisted of 73 subjects with operated congenital cleft lip and palate subjects(53 males, 20 females) and 110 control subjects (7 males, 34 females) ranging from 3 to 14 years old. Each group was divided into four age groups (3-5, 6-8, 9-11, 12-14 year) and analyzed by Cohen's method and Burstone's method. The following conclusions were obtained ; 1. In Wit's appraisal, there was no difference the cleft lip and palate subjects and the control subjects. 2. In the cleft lip and palate subjects, they had smaller and more retrusive maxilla than the control subjects in both sexes. 3. In the cleft lip and palate subjects, they had more retrusive mandible than the control subjects in both sexes. 4. In the cleft lip and palate subjects, they had more concave profile than the control subjects.

In cleft lip and/or palate patients with the complex congenital heart diseases, surgical repair of the cleft lip and/or palate has been postponed after the open heart surgery because the heart problem of the patient might cause more complications associated with anesthesia and surgery. There has been little report about experiences in the surgical management of these patients and optimal time of surgical intervention. Authors are introducing the experiences of performing corrective surgery of cleft lip and/or palate in the patients with congenital heart diseases before and after the open heart surgery. We managed five patients from May 1992 to March 2004. Two patients were male and the rest were female. One of them had cleft lip alone and others had cleft lip and palate. Two of them underwent delayed cleft lip and/or palate surgery after open heart surgery, and the rest had immediate intervention for cleft lip and/or palate. There was no complication during the operation and postoperative period. There would be no need to delay the corrective surgery of the cleft lip and/or palate after the open heart surgery, if solid medical team approach was available with the pediatric cardiologist and the anesthesiologist.

Purpose: The authors accessed the anthropometric measurements of fourty non-cleft normal a three-month-old infant and using this obtained data as a basic guideline, authors applied the modified Noordhoff technique for the treatment of bilateral cleft lip. Methods: Over a period of 10 years, a total of 21 bilateral cleft lips were operated. 13 cases of complete and 8 cases of incomplete bilateral cleft lip and palate. In the complete type of bilateral cleft palate, elastic head cap and passive intraoral appliance were applied at 1 to 2 week of age for 2 months duration. The definitive cheiloplasty was performed at 3 months of age using the modified Noordhoff technique. Results: After a follow-up period ranging one to nine years, most patients presented with cosmetically and functionally satisfying results, with an exception of two cases where an undesired peaking effect of the vermilion and dimpling of the vermilion mucosa was encountered. Conclusion: Accessing the anthropometric measurements of fourty non-cleft normal three-month-old infant and using this obtained dara as a guideline, the modified Noordhoff technique can be applied to either complete or incomplete bilaterally cleft lip providing more naturally pleasing and cosmetically satisfying scars that lie in harmony with the philtral ridges, lip tubercle positioned just below the vermilion and a distinct white line and Cupid's bow.

The characteristics of the cleft lip nasal deformity is defined in this article in three planes. The alar flaring is explained in X axis, the lower positioning of the alar free margin is imagined in Y axis and the short hemicolumella is in Z axis. Most cleft surgeons have focused on the malposition of the lateral crus of alar cartilage while the author defined it in X and Y axises and tried to correct that deformity of short hemicolumella in Z axis. For the last 13 years the author applied that method in 818 cases of secondary cleft lip nose deformity. Through the columellar splitting incision extended to free margin of the alar not beyond the nasal dorsum, the skin and soft tissue of the webbing deformed the nasal tip was excised in crescent fashion. The dissected short hemicolumella including the medial crus was thus elevated and advanced into the space of the deformed nasal tip after the crescent excision. This procedure should be followed by the correction of the deformities in X and Y axis. The medial crus elevation is more effective and critical way to have the constant and nice outcome than the lateral crus reposition in secondary cleft lip nasal deformity
