Purpose: To determine the incidence, risk factors, and clinical characteristics of pelvic insufficiency fracture (PIF) in patients with cervical cancer. Materials and Methods: Between July 2004 and August 2009, 235 patients with non-metastatic cervical cancer were treated with definitive chemoradiation or postoperative radiotherapy. Among 235 patients, 117 (49.8%) underwent the first positron emission tomography/computed tomography (PET/CT) within 1 year after radiotherapy. The median radiation dose was 55 Gy (range, 45 to 60 Gy). Medical charts and imaging studies, including PET/CT, magnetic resonance imaging (MRI), CT. bone scintigraphy were reviewed to evaluate the patients with PIF. Results: Among 235 patients, 16 developed PIF. The 5-year detection rate of PIF was 9.5%. The 5-year detection rate of PIF in patients who underwent the first PET/CT within a year was 15.6%. The median time to development of PIF was 12.5 months (range, 5 to 30 months). The sites of fracture included 12 sacroiliac joints, 3 pubic rami, 3 iliac bones, and 1 femoral neck. Eleven of 16 patients having PIF complained of hip pain requiring medications. One patient required hospitalization for pain control. The significant risk factors of PIF were old age, body mass index less than 23, bone mineral density less than -3.5 SD, and the first PET/CT within a year after radiotherapy. Radiation dose and concurrent chemotherapy had no impact on PIF rate. Conclusion: PIFs were not rare after pelvic radiotherapy in cervical cancer patients in the era of PET/CT. Timely diagnosis and management of PIF can improve quality of life in patients with cervical cancer, in addition to reducing unnecessary medical expenses.

This study aims to provide information about the acute poisoning patients transferred by 119 ambulance service for nurses and emergency medical technicians. The data is based on 119 ambulance services patients charts of Seocho area in Seoul. The results were as follows: 1. Total number of emergency patients all over the country has been nearly fourtimes in 1995 compared to 1991. Total number of emergency patients were 322.051 in 1994. 2. About $35\%$ of total E.R. patients were transferred by 119 ambulance services in Seoul in the last 5years. Acute drug intoxication patients occupied $2-3\%$ of E.R. patients in Seoul. 3. About $4\%$ of E.R. patients in Seoul were transferred by 119 E.R. services of Seocho area in Seoul in 1995. Among them $2.4\%$ patients were drug intoxication patients. 4. Data were collected from available patients of 119 ambulance services from Jan. 1993 to Dec. 1995 in Seocho area. Total poisoning patients were 184. - The female/male ratio was 69.7:30.4 and most of patients$(69.7\%)$ were in the age of 20th and 30th. - The busy time of calling 119 ambulance service was from 6P.M. to midnight$(37.5\%)$ - It took within 10 minutes for patients$(62.8\%)$ from notification to arrival in hospital. - Regarding poisoning substances. hypnotics $(22.8\%)$, tranquilizer$(14.7\%)$, agricultural agents$(6.0\%)$ rodenticide$(27\%)$ and others $(10.3\%)$ were in order and unknown were $43.5\%$. - Most of the patients or protector $(72.8\%)$ chose hospitals. Among them $(87.3\%)$ were general hospital. - The most predominant symptoms were coma$(22.3\%)$. dizziness$(6.5\%)$ and then allergy. vomiting. gastrointestinal cramps etc. - Airway management and oxygen administration together was the main medical control of prehospital emergency medical services$(33.7\%)$. It is proposed that first, a systematic survey of drug intoxication patients must be conducted to give an appropriate prehospital emergency care for the emergency medical technician and second, a wide and regular public education to improve understanding of first aids should be undertaken.

Aim: To determine whether beta-blockers (BBs) improve the overall survival (OS) of patients with metastatic non-small cell lung cancer (NSCLC). Materials and Methods: The medical charts of 107 patients with metastatic NSCLC were retrospectively assessed. Thirty-five patients (BB group) using BBs during chemotherapy (CT) were compared with 72 controls [control=(C) group] who did not use BBs following the diagnosis of NSCLC. The histological tumor subtype, performance status (ECOG), age, gender, smoking status, comorbidities, other medications and chemotherapeutics that were received in any line of treatment were recorded. We compared the overall survival (OS) of the patients in the BB and C groups. Results: The mean age of the patients was 61 years (range 42-81 years) and all patients were administered CT. The BB group was more likely to have HT and IHD and was more likely to use RAS blockers (p<0.01 for all) compared with the C group, as expected. The mean follow-up time was 17.8 months (range 1-102 months) for the entire group. The most commonly prescribed BB agent was metoprolol (80% of cases). At the time of the analysis, 74 (69%) of all patients had died. In the univariate analysis the median overall survival (OS) was 19.25 (${\pm}2.87$) months (95%CI: 13.62-24.88) in the BB group and 13.20 (${\pm}2.37$) months (95%CI: 8.55-17.85) in the C group (p=0.017). However, the benefit of BBs on survival disappeared in the multivariate analysis. Conclusions: The use of BBs during CT may be associated with an improved OS for patients with metastatic NSCLC.

Purpose: To compare and confirm the impact of prepregnancy body mass index on pregnancy outcome in women with a singleton conceived by assisted reproductive technology and spontaneously conceived pregnancy. Methods: A sample of 165 and 247 pregnant women with and without assisted reproductive technology were retrospectively recruited from electronic medical charts of C hospital. Results: There were significant differences between the two groups for maternal age, paternal age, length of marriage, prepregnancy body mass index, parity, spontaneous abortion experience, and preterm delivery. A prepregnancy body mass index of ${\geq}25$ was associated with higher risk for maternal and neonatal complication in the assisted reproductive technology group. Conclusion: The results indicate that a higher prepregnancy body mass index is associated with increased risks for adverse pregnancy outcomes for women using assisted reproductive technology. So these women need appropriate care to compensate for the risk.

Hospitals these days are trying to introduce the a practice has recently been generalized in the test or diagnosis process, where test results and images from different test labs are interlinked together. This process is identical to that of physical aspect in EMR process, which computerizes the paper results within the hospital. One of the prerequisites for the process of computerizing test results is the interface between clinical test devices in the test labs. However, due to the variety of prescription inputs, disparity of test result papers, complexity of job in test labs and diversify of interfaces among the different devices, interconnection with the hospital information system is a complicated job. A universal control of clinical test devices which have independent communication protocols has become possible by connecting them with an interface workstation. As for the patients, waiting time for test has been reduced, and, thanks to the synchronized result retrieval system, it has become possible to check the test results on the very day of the test. As a result, the length of hospitalization has been reduced, too. In terms of workflow, as the transfer of charts and transfer of result papers are separated, the embarrassing job of collecting result papers has disappeared. As patients' test appointment and the results processing can be made on-line, extra work for doctors have disappeared. And, thanks to the computerization of test results information management, the job of statistical processing has become convenient.

Initial prevention activities and rapid propagation conditions is the most important to prevent diffusion of water pollution. If water pollutants flow into streams river or main stresm located in environmental conservation area or water intake facilities, we must predict immediately arrival time and the diffusion concentration to the proactive. National Institute of Environmental Research developed water pollution incident response prediction system linking dam and movable weir. the system is mathematical model which is updated daily. Therefore it can quickly predict the arrival time and the diffusion concentration when there are accident of oil spills and hazardous chemicals. Also we equipped with mathematical model and toxicity model of EFDC(Environmental Fluid Dynamics Code) to calculate the arrival time and the diffusion concentration. However these systems offer the services of an offline manner than real-time control services. we have ensured the reliability of data collection and have developed a real-time water quality measurement data transmission device by using the data linkage utilizing a mode bus communication and a commercial SCADA system, in particular, we implemented to be able to do real-time water quality prediction through information infrastructure of the water quality integrated management business created by utilizing the construction of the real-time prediction system that utilizes the data collected, the Open map, the visual representation using charts API and development of integrated management system development based on web maps.

Background: The seropositivity rate of hepatitis B surface antigen (anti-HBs) antibodies is known to be ≥95% after hepatitis B virus vaccination during infancy. However, a low level or absence of anti-HBs in healthy children is discovered in many cases. Recent studies in adults reported that a reduced anti-HBs production rate is related to obesity. Purpose: To investigate whether body mass index (BMI) affects anti-HBs levels in healthy children following 3 serial dose vaccinations in infancy. Methods: We recruited 1,200 healthy volunteers aged 3, 5, 7, or 10 years from 4-day care centers and 4 elementary schools. All subjects completed a questionnaire including body weight, height, and vaccine type received. Levels of serum hepatitis B surface antigen (HBsAg) and anti-HBs in all subjects were analyzed using electrochemiluminescence immunoassay. The standardized scores (z score) for each sex and age were obtained using the lambda-mu-sigma method in the 2017 Korean National Growth Charts for children and adolescents. Results: Our subjects (n=1,200) comprised 750 males (62.5%) and 450 females (37.5%). The overall anti-HBs seropositivity rate was 57.9% (695 of 1,200). We identified significant differences in mean BMI values between seronegative and seropositive groups (17.45 vs. 16.62, respectively; P<0.001). The anti-HBs titer was significantly decreased as the BMI z score increased adjusting for age and sex (B=-15.725; standard error=5.494; P=0.004). The probability of anti-HBs seropositivity based on BMI z score was decreased to an OR of 0.820 after the control for confounding variables (95% confidence interval, 0.728-0.923; P=0.001). Conclusion: There was a significant association between anti-HBs titer and BMI z score after adjustment for age and sex. Our results indicate that BMI is a potential factor affecting anti-HBs titer in healthy children.

The purpose of this study was to investigate the biomechanical of K-Pop dance movement. The study was conducted on 15 male and 15 female subjects in 20-30 age groups. And they choose 150 K-Pop dance choreographies in the top 10 ranking of the main charts. We analyzed the RoM, joint moment and impulse force of the highlight movements. First, During the K-Pop dance motion, the usage of knee joints are more than the hip joints and the ankle joints, and female dancers has a larger range of motion than the male dancers. Second, male dancer uses more than female dancers when they compared the load of male dancers and female dancers. In particular, flexion and extension of the hip joints are mostly used in this study. Third, the impulse force of male dancers was greater than of female dancers, but it was statistically insignificant, this is equal to the impulse on walking. In conclusion, Female dancers use more range of motion than male dancers, but male dancer choreography requires greater torque, which can strain joints. Most choreographic exercises involve movements such as hip joint, knee joint, flexion of ankle joint, extension, rotation, and jumping.
