Crohn disease is a chronic transmural inflammatory disease that may involve any portion of the gastrointestinal tract. An increased incidence of Crohn disease in the general population has been reported, along with a greater than threefold increase of Crohn disease in children under the age of 16 years noted in a recent study. Crohn disease may be seen as early as infancy, but the most common pediatric age of onset is during the teenage period. We experienced a case of Crohn disease in 6 year old male child complained abdominal pain, oral aphthous ulcers, arthralgia, anorexia, and growth failure. A brief review of related literature is also presented.

기상학적 및 수문학적 가뭄지수를 활용한 가뭄 전이 및 피해 특성 분석

김지은,손호준,김태식,김원범,김태웅,Kim, Ji Eun,Son, Ho-Jun,Kim, Taesik,Kim, Won-Beom,Kim, Tae-Woong 대한토목학회 2024 대한토목학회논문집 Vol.44 No.3

가뭄 전이는 기상학적 가뭄이 오랜기간 지속되어 수문학적 가뭄으로 발달하는 현상으로 가뭄 전이 사상은 비전이 가뭄사상보다 지역에 큰 피해를 야기한다. 기존에 수행된 가뭄 전이 연구들은 주로 상관분석을 통해 지체시간을 파악하고 있으며, 가뭄 전이 및 비전이 사상 간의 피해 양상을 비교하는 연구는 부족한 실정이다. 본 연구에서는 충청권역 시군구 단위의 가뭄지수를 활용하여 기상학적 및 수문학적 가뭄간의 중복전이 및 풀링전이를 고려하여 가뭄 전이 여부를 판단하고, 가뭄의 전이 특성(풀링, 감쇠, 지체, 연장)을 분석하였다. 분석 결과 충청북도 충주시에서 2010년 기상학적 가뭄(비전이 사상)이 발생하였으나, 가뭄 피해는 발생하지 않았다. 하지만, 2017-2018년에 발생한 가뭄은 기상학적 가뭄이 수문학적 가뭄으로 전이되면서 심도는 약하지만 지속기간이 길어짐에 따라 가뭄으로 인한 피해가 발생하였다. 이와 비슷하게 2017년 청양군에서는 기상학적 가뭄(비전이 사상)이 발생하였으나, 가뭄 피해는 발생하지 않았다. 하지만, 바로 인접지역인 부여군에서는 동일한 기간에 비슷한 크기의 기상학적 가뭄이 수문학적 가뭄으로 전이되어 가뭄으로 인한 피해가 발생하였다. 본 연구를 통해 비전이 사상보다 전이 사상에서 피해가 심각한 것을 확인하였으며, 이러한 결과는 지역에 적합한 가뭄 대응 정책을 수립하는데 기초자료로 활용할 수 있다. Sustained meteorological drought can lead to hydrological drought, known as drought propagation. The propagated droughts cause more damage to the region than the non-propagated droughts. Recent studies on drought propagation have focused on identifying the lag time using correlation analysis. There is a lack of studies comparing damage patterns between propagated and non-propagated droughts. In this study, the overlap and pooling propagation between meteorological and hydrological droughts were analyzed using drought indices in Chungcheong Province to identify drought propagation, and the propagation characteristics such as pooling, attenuation, lag and extension were analyzed. The results showed that although Chungju-si experienced a meteorological drought in 2010, no damage was caused by the drought. However, a meteorological drought in 2017 and 2018 propagated into a hydrological drought of longer duration but less severity, resulting in drought-affected damage. Similarly, Cheongyang-gun experienced a meteorological drought in 2017, but no damage was reported from the drought. However, in the neighboring county of Buyeo-gun, a meteorological drought with a similar magnitude propagated to a hydrological drought during the same period, resulting in drought-affected damage. The overall results indicated that the damage from propagated drought events was more severe than the non-propagated drought events, and these results can be used as basic data for establishing drought response policies suitable for the region.

Chronic exposure to high levels of manganese leads a pronounce and debilitating disorder known as manganism. Research on the toxic manifestation of manganese have focused primarily on its neurological effects because exposure to high levels of the metal produces a distinct and irreversible extrapyramidal dysfunction resembling the dystonic movements associated with Parkinson's physiological and biochemical systems in the body. The purpose of this study was to evaluate the effect of manganeses on primary rat calvarial cell growth and toxicity. The experimental groups were in concentration of 0, 10, 30, 60, 100, 300 ${\mu}M$. Cell activity was assessed at day 1 and day 3 using a fluorescent molecular probe. Cell proliferation was evaluated at day 1 and day 3 by MTT assay. The amount of total protein synthesis was measured at day 3 and day 7. The results were as follows: The proliferation of primary rat calvarial cells were inhibited by $MnCl_2$ in the concentration exceeding $100{\mu}M$. The primary rat calvarial cells treated with $MnCl_2$ showed similar protein synthesis to the control group except in 100 ${\mu}M$. These result suggest that manganese suppress the viability and protein synthesis of primary rat calvarial cells in concentration exceeding $100{\mu}M$.

We developed a four-channel first order gradiometer system to measure magnetoencephalogram for mice. We used double relaxation oscillation SQUID (DROS). The diameter of the pickup coil is 4 mm and the distance between the coils is 5 mm. Coil distance was designed to have good spatial resolution for a small mouse brain. We evaluated the current dipole localization confidence region for a mouse brain, using the spherical conductor model. The white noise of the measurement system was about 30 fT/$Hz^{1/2}$/cm when measured in a magnetically shielded room. We measured magnetic signal from a phantom having the same size of a mouse brain, which was filled with 0.9% saline solution. The results suggest that the developed system has a feasibility to study the functions of brain of small animals.

The Ultra Fast Flash Observatory (UFFO) pathfinder consists of the UFFO Burst Alert X-ray Trigger telescope (UBAT) and the Slewing Mirror Telescope (SMT). They are controlled by the UFFO Data Acquisition system (UDAQ). The UBAT triggers Gamma-Ray Bursts(GRBs) and sends the position information to the SMT. The SMT slews the motorized mirror rapidly to the GRB position to take the UV/Optical data within a second after trigger. The UDAQ controls each instrument, communicates with the satellite, collects the data from UBAT and SMT, and transfers them to the satellite. Each instrument uses its own field programmable gates arrays (FPGA) for low power consumption and fast processing, and all functions are implemented in FPGAs without using microprocessors. The entire electronics system of the UFFO pathfinder including architecture, control, and data flow will be presented.

Objectives By analyzing data of the pediatric patients who had visited the emergency room of the oriental medical hospital, we can understand their characteristics and diseases. The purpose of this study was to introduce the excellence of the Oriental medicine, to develop various treatments, and to revitalize pediatric emergency care at the oriental medical hospital. Methods The study was composed of 334 pediatric patients who had visited the emergency room of the ${\bigcirc}{\bigcirc}$ university oriental hospital from January 2011 to December 2013. Results 1. It has showed that between 7 to 12 years old patients (27.8%) were the most common age populations. 2. The number of pediatric patients was increased during February. According to the weekly distribution data, the number of pediatric patients who had visited on Sunday was the highest (28.7%). Also, the number of pediatric patients who had visited the ER between 21 to 24 hours (29.0%) was the highest. 3. The two major reasons for inpatient hospitalization were digestive and nerve-related symptoms. Nerve-related symptoms were the most common in infants while digestive symptoms were the most common in other child development stages. 4. The duration of time interval from the onset of symptoms to the ER visit was most commonly within 6 hours (50.3%). An acupuncture and herbal medication treatment (70.1%) were the most common medical treatments. The majority of the pediatric patients (95.5%) were discharged after their medical treatments. Conclusions A serious acute illness was not the most common reason for the ER visit among the pediatric patients. The most common disease states that have preferred to be treated with the oriental medicine were dyspepsia, crying, facial palsy, and ankle sprain. We have to introduce the excellence of the oriental medicine. We also need to try developing other treatments such as magnetic acupuncture, aromatherapy, and revitalizing pediatric emergency care at the oriental medical hospital.

The purpose of this study is to evaluate the effectiveness of online and offline blended education for hygiene and safety management of children's foodservice operations in Eunpyeong-gu. For the teachers of the children's foodservice operations, two online sessions and one offline session were conducted with different educational themes each time. In terms of satisfaction with the education, the online program 'Mission Possible' scored 4.8 points and the collective education of teachers and staff scored 4.6 points, indicating that the training composition and communication with the person in charge were high. In other field opinions, it was found that online and offline education according to the situation was very helpful in the overall management of the children's foodservice operations. With fewer face-to-face opportunities, there were difficulties in on-site support and management. To supplement this, various programs were applied to help children's foodservice operations provide healthy and safe meals and snacks.

The successful use of osseointegrated implants to replace missing teeth has been demonstrated for both the completely and the partially edentulous patients. Many studies have confirmed an excellent long-term prognosis. The successful outcome of any implant procedure is surely dependent on the interrelationship of the various components that includes the following: biocompatibility of the implant material, macroscopic and microscopic nature of the implant surface, the status of the implant bed in both a health(noninfected) and a morphologic(bone quality) context, the surgical technique, the undisturbed healing phase, the subsequent prosthetic design, and long-term loading phase. Periodontally compromised patients have poor status of the implant bed and periodontal pathogen. No longitudinal data are available whether these factors affect the prognosis of implants. In this study, 102 machined $Br{{\aa}}nemark$ implants are inserted to analyze the success rate of 1-4 years and marginal bone loss in 49 chronic periodontitis patients. The following conclusions could be drawn from this study. 1. The cumulative success rate of implants at the 4-year of loading was 95.10%. 2. 5 failed implants have been removed. One implant have been removed due to infection, two implants were removed due to failure of osseointegration. and other two implants were removed due to mechanical failure caused by over-loading. 3. Mean marginal bone loss from the time of loading was 0.94mm at first year, 1.12mm at second year, 1.25mm at third year. These results suggest that implant therapy is good treatment modality in chronic periodontitis patients, and periodontal treatment including oral hygiene program is completed prior to insertion of implants.
