Despite the current accomplishments with the repair of cleft lips, the surgical management of the nasal deformity remains a functional and aesthetic dilemma for patients, their families, and reconstructive surgeons. Recent improvements in the understanding and technical execution of te primary cleft lip repair have significantly reduced secondary sequelae and the consequent need for secondary surgical correction. But, secondary surgical corrections are necessary according to numerous factors. Such factors include the secondary surgical corrections are necessary according to numerous factors. Such factors include the severity of the initial deformity, the surgical plan, precision of execution of the primary repair, and success of the postoperative management. We preformed the secondary correction of cleft lip and palate in 11 patients via various methods. In conclusion, primary repair of cleft lip and palate patients is the most important to prevent the secondary deformities, and most of cleft lip and palate with secondary deformities must be treated with combined cheiloplasty and rhinoplasty.

Purpose: Obesity in children and adolescents can cause diabetes mellitus, hyperlipidemia, cardiovascular diseases and renal diseases. The aim of the present study is to examine the change of renal function according to obesity index in children and adolescents. Methods: Data of 72 children and adolescents aged between 5 years and 16 years without clinical evidence of renal diseases were included in the study. From January 2007 to June 2007, blood samples were collected from children and adolescents who were seen at the Department of Pediatrics at Chung-Ang University Yongsan Hospital. Obesity degree and body mass index (BMI) were measured, and glomerular filtration rate (GFR) was estimated from the formula as described by Léger and colleagues. Results: The mean GFR value was significantly higher in the obese group (BMI >95 percentile, 94.09±28.04 ml/min) than in the non-obese group (BMI <95 percentile, 74.29±19.56 ml/min) divided by BMI (p=0.001). The mean GFR value was significantly higher in the obese group (obesity degree >120 percent, 93.57±28.26 ml/min) compared with the non-obese group (obesity degree <120 percent, 73.72±18.77 ml/min) divided by obesity degree (p=0.001), too. GFR was correlated positively with BMI (r²=0.404, p=0.000) as well as obesity degree (r²=0.119, p=0.003). Moreover, there was a positive correlation between BMI and GFR in the non-obese group (r²=0.350, p=0.000). Conclusion: Obesity may lead to an alteration of renal hemodynamics such as hyperfiltration, appropriate control and management for obesity is necessary.

In this paper, we proposed a variable-impedance microstrip circuit using DGS (Defected Ground Structure) and control device. The proposed variable-impedance transmission line with a simple planar antenna can change the resonant frequency and the input impedance of antenna to achieve the DAM (Direct Antenna Modulation). As an application example of the variable-impedance microstrip, we have implemented the ASK modulation of RF signal for the low-power consumption RFID applications. The experimental results show that a patch antenna with a resonant frequency of 2.45 GHz and a 30 MHz bandwidth can transmit a 1 Mbps digital modulated signal with the ultra low-power consumption.

Bilateral cleft lip reconstruction can be performed in one-or two-stages. The choice depends on the surgeon's proficiency and experience. However the type and severity of the cleft must be considered. Complete or incomplete symmetric, bilateral clefts in which the premaxilla is within the alveolar arch or slightly protruded can be successfully treated with simultaneous lip reconstruction on both sides. There are some advantages that one-stage lip reconstruction facilitates creation of a symmetric and balanced lip, retraction of protruding premaxilla and the parent's psychologic satisfaction. However, there are some disadvantages such as micrognathia of the upper jaw by severe scar formation and poor adaptation of flap margins by severe tension. The surgeon must be able to judge and exploit the advantages offered by one-stage approach. We present the case report of one-stage reconstruction of primary bilateral cleft lip with literature reviews.

Are Adolescents with Internet Addiction Prone to Aggressive Behavior? The Mediating Effect of Clinical Comorbidities on the Predictability of Aggression in Adolescents with Internet Addiction

<P>Previous studies have reported associations between aggression and Internet addiction disorder (IAD), which has also been linked with anxiety, depression, and impulsiveness. However, the causal relationship between aggression and IAD has thus far not been clearly demonstrated. This study was designed to (a) examine the association between aggression and IAD and (b) investigate the mediating effects of anxiety, depression, and impulsivity in cases in which IAD predicts aggression or aggression predicts IAD. A total of 714 middle school students in Seoul, South Korea, were asked to provide demographic information and complete the Young's Internet Addiction Test (Y-IAT), the Buss-Perry Aggression Questionnaire, the Barratt Impulsiveness Scale-11, the State-Trait Anger Expression Inventory-2, the Beck Anxiety Inventory, the Beck Depression Inventory, and the Conners-Wells Adolescent Self-Report Scale. Three groups were identified based on the Y-IAT: the usual user group (n=487, 68.2%), the high-risk group (n=191, 26.8%), and the Internet addiction group (n=13, 1.8%). The data revealed a linear association between aggression and IAD such that one variable could be predicted by the other. According to the path analysis, the clinical scales (BAI, BDI, and CASS) had partial or full mediating effects on the ability of aggression to predict IAD, but the clinical scales had no mediating effect on the ability of IAD to predict aggression. The current findings suggest that adolescents with IAD seem to have more aggressive dispositions than do normal adolescents. If more aggressive individuals are clinically prone to Internet addiction, early psychiatric intervention may contribute to the prevention of IAD.</P>

Recently, various technologies have been devised to convert methane, a main ingredient of natural gas and biogas, into hydrogen as part of efforts to develop new low pollution energies and reduce greenhouse gases. This study, different from existing methods of reformation, suggests a new form of a partial oxidation compression ignition reformer, to which the concept of super-adiabatic combustion is applied. In addition, the study also conducts experiments by variables about the oxygen/methane ratio, the total flow rate. the intake preheating temperature and the oxygen enrichment ratio, all of which affect the production of hydrogen, in order to understand the optimal feature of the reformer's movement. Results showed that the concentration of hydrogen was 20.84%, under the optimal standard condition of oxygen/methane ratio 0.26, total flow rate 106.5 L/min and intake preheating temperature 355℃. Under the same condition, the concentration of hydrogen became 20.31% when the oxygen enrichment ratio was 55.6%.

저자들은 56세 여성 환자의 왼쪽 쇄골 하 정맥에 시행한 이식형 약제주입기 카테터의 삽입 후 발생한 비정상 위치에 대한 증례를 보고하고자 한다. 카테터의 끝은 환자의 늘 어진 가슴, 체위, 신체의 움직임, 카테터의 유동성 등의 영향으로 천자된 정맥 내에서 견인되고 뒤쪽으로 이동하였다. 환자는 어떠한 증상도 호소하지 않았지만 비정상 위치의 카테터는 심각한 합병증을 유발할 수 있기 때문에 제거되었다. 따라서 시술자는 약제주입기 삽입 전에 환자의 신체 상태와 단순 흉부 촬영상을 확인하고 카테터의 비정상 위치가 발생할 수 있는 위험 징후를 알아차려야 하겠다.

purpose : The increased uptake on the bone scan represents the zone of increased bon metabolism. Single photon emission computerized tomography(SPECT) is more precise in detecting lesions of increased uptake than planar bone scan. The purpose of this study is to examine applicability of bone SPECT to shoulder lesions and to analyze the efficacy of SPECT compared with simple X-ray in rotator cuff lesion. Materials and Methods : Subjects were 21 patients with of rotator cuff lesion confirmed by surgical(arthroscopic or open) procedure. Increased uptake(bone SPECT) and sclerosis of greater tuberosity and anterior acromion on X-ray were considered positive. Results : For acromion, sensitivity of the bone SPECT was 90.9% and specificity was 50.0%. For greater tuberosity, sensitivity was 92.3% and specificity 37.5%. For acromioclavicular joint, sensitivity was 80.0% and specificity 81.3%. Conclusion : This study demonstrates that the uptake of radioisotope in shoulder is increased in patients with painful partial or total rotator cuff tear. And extrinsic mechanical pressure seems to be the cause of rotator cuff lesion of the shoulder.
