Purpose: The purpose of this study was to investigate the knowledge and practice level of infection managements in child guardians with respiratory infections after H1N1 diffusion of 2009. Methods: The data were collected during February and March 2010 using a self-report questionnaire. The participants were 228 child guardians. Data were analyzed using frequency, percentage, means, SD, t-test, F-test, Pearson correlation coefficients, and Cronbach's alpha with the SPSS 17.0 program. Results: Mean age of the guardians and children were 37.8 years, 4.1 years respectively. For knowledge level of respiratory infections, hand washing method had the highest score and snuffles prevention method, the lowest. For practice level for respiratory infections, environmental hygiene management had the highest score and symptom management, the lowest. Infection management knowledge and practice level had a positively significant correlation in every area. Conclusion: The results indicate the necessity of continual education on infection management, and that the most efficient timing for the education appears be for participants during their first pregnancy or after the woman has delivered her child.

Background: The purpose of this study was to compare the clinical safety and effect with and without additional submucosal midazolam to oral chloral hydrate and hydroxyzine when used for pediatric conscious sedation in a clinical dental environment. Methods: Thirty one cases of pediatric conscious sedations were performed in this study. Selection criteria included good health (ASA I), under 6 years old, 20 kg of body weight, uncooperative behavior and the need for sedation to receive dental treatment including anesthesia and restorative or surgical procedure for at least two teeth. In each visit, patients were randomly assigned into one of two groups; CH group: chloral hydrate (60 mg/kg), hydroxyzine (1 mg/kg), CH-M group: chloral hydrate (60 mg/kg). hydroxyzine (1 mg/kg) and submucoal midazolam (0.1 mg/kg). 50% nitrous oxide-oxygen was maintained during the sedation period Sedations were monitored using a pulse oximeter for estimating pulse rate (PR) and percutaneous oxygen saturation ($SpO_2$). Behavior response rated using Houpt's scale and need of restraint was assessed every 2 minutes through 30 minutes of operative procedure reviewing the videotape recording. Evaluation of overall behavior success was performed using modified overall behavior rate of Houpt's scale. Data was analyzed using t-test. Results: PR and $SpO_2$ for both groups remained within the normal values. The mean scores for sleep and movement of CH-M group were higher than those of CH group (P < 0.05). There were no significant difference in mean score for crying between two groups. The mean scores of overall behavior of CH-M group was higher than those of CH group (P < 0.01). Reinstraint of CH-M group was less required than that of CH group (P < 0.05). Conclusions: Oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) combined with submucosal injection of midazolam was safer and showed more improved sedation effect than oral chloral hydrate (60 mg/kg) and hydroxyzine (1 mg/kg) without midazolam for sedation of pediatric dental patients.

대기 중 메탄의 해양 흡수와 방출 메커니즘은 생지화학 순환이 갖는 복잡성과 해양-대기 경계면에서 지역 규모 혹은 기작 단위에서의 관측 연구 부족으로 잘 알려져 있지 못하다. 그러나 다양한 시 공간적 규모에서 탄소 수지와 순환을 조절하는 해양 메커니즘에 대한 완전한 이해 없이는, 해양의 탄소 변동과 전 지구적 지역적 기후 변화에 미치는 영향을 예측하기란 불가능하다. 표층해양 및 해양대기에서 용존 메탄의 탄소동위원소 조성에 대한 정밀한 연속 관측은 해양-대기 경계면에서의 유 출입 및 생산 소모 과정에 대한 추가적인 정보를 제공한다. 본 연구는 최근 급격히 발전한 광학기반 동위원소 분석 기기들을 개괄적으로 소개하고, 표층 양 내 용존 메탄과 해양대기 메탄의 탄소동위원소 실시간 연속 측정으로의 적용을 위해, 현재 이들 기기들의 기술 및 활용 현황을 논의한다. 이어 레이저 광원의 흡수분광기 중 하나로, 사용이 최근 급증하고 있는 광공동 링다운분광기(CRDS, Cavity Ring Down Spectroscopy)기반 동위원소 분석기기를 예시로 하여 연속 관측 시스템의 운용, 최적화 조건, 보정법을 제안하며, 기체 시료로부터 실시간 관측된 메탄 농도 및 메탄 탄소동위원소의 관측 예를 소개하고자 한다. 이러한 가능성 검토를 통해 향후 해양 환경에서의 실시간 메탄 탄소동위원소 분석 연구의 방향을 제안하고자 한다. The mechanisms of $CH_4$ uptake into and release from the ocean are not well understood due mainly to complexity of the biogeochemical cycle and to lack of regional-scale and/or process-scale observations in the marine boundary layers. Without complete understanding of oceanic mechanisms to control the carbon balance and cycles on a various spatial and temporal scales, however, it is difficult to predict future perturbation of oceanic carbon levels and its influence on the global and regional climates. High frequency, high precision continuous measurements for carbon isotopic compositions from dissolved $CH_4$ in the surface ocean and marine atmosphere can provide additional information about the flux pathways and production/consumption processes occurring in the boundary of two large reservoirs. This paper introduces recent advances on optical instruments for real time $CH_4$ isotope analysis to diagnose potential applications for in situ, continuous measurements of carbon isotopic composition of dissolved $CH_4$. Commercially available, three laser absorption spectrometers - quantum cascade laser spectroscopy (QCLAS), off-axis integrated cavity output spectrometer (OA-ICOS), and cavity ring-down spectrometer (CRDS) are discussed in comparison with the conventional isotope ratio mass spectrometry (IRMS). Details of functioning and performance of a CRDS isotope instrument for atmospheric ${\delta}^{13}C-CH_4$ are also given, showing its capability to detect localized methane emission sources.

Fenofibrate is a selective peroxisome proliferator-activated receptor α (PPARα) activator and is prescribed to treat hyperlipidemia. The mechanism through which PPARα agonists reduce food intake, body weight, and adiposity remains unclear. One explanation for the reduction of food intake is that fenofibrate promotes fatty acid oxidation and increases the production of ketone bodies upon a standard experimental dose of the drug (100∼300 mg/kg/day). We observed that low-dose treatment of fenofibrate (30 mg/kg/day), which does not cause significant changes in ketone body synthesis, reduced food intake in Long-Evans Tokushima (LETO) rats. LETO rats are the physiologically normal controls for Otsuka Long-Evans Tokushima Fatty (OLETF) rats, which are obese and cholecystokinin (CCK)-A receptor deficient. We hypothesized that the reduced food intake by fenofibrate-treated LETO rats may be associated with CCK production. To investigate the anorexic effects of fenofibrate in vivo and to determine whether CCK production may be involved, we examined the amount of food intake and CCK production. Fenofibrate-treated OLETF rats did not significantly change their food intake while LETO rats decreased their food intake. Treatment of fenofibrate increased CCK synthesis in the duodenal epithelial cells of both LETO and OLETF rats. The absence of a change in the food intake of OLETF rats, despite the increase in CCK production, may be explained by the absence of CCK-A receptors. Contrary to the OLETF rats, LETO rats, which have normal CCK receptors, presented a decrease in food intake and an increase in CCK production. These results suggest that reduced food intake by fenofibrate treatment may be associated with CCK production.
