Applicability of 8 day interval flow data for the calibration of hydrologic model was evaluated using Hydrological Simulation Program-Fortran (HSPF) at Kyungan watershed. The 8 day interval flow monitored by Ministry of Environment located at upstream was calibrated and periodically validated during 2004-2008. And continuous daily flow monitored by Ministry of Construction & Transportation (MOCT) and located at the mouth was compared with daily simulated data during 2004-2007 as spatial validation. Automatic calibration tool which is Model-Independent Parameter Estimation & Uncertainty Analysis (PEST) was applied for HSPF calibration procedure. The model efficiencies for calibration and periodic validation were 0.63 and 0.88, and model performances were fair and very good, respectively, based on criteria of calibration tolerances. Continuous daily stream flow at the mouth of Kyungan watershed were good agreement with observed continuous daily stream flow with showing 0.63 NS value. The PEST program is very useful tool for HSPF hydrologic calibration using non-continuous daily stream flow as well as continuous daily stream flow. The 8 day interval flow data monitored by MOE could be used to calibrate hydrologic model if the continuous daily stream flow is unavailable.

This study evaluated the types of daily routines that occurred in child care centers based on four general categorizations: time spent on indoor free choice activities, outdoor activities, group activities and special activities. In addition, resulting child care teacher behaviors were examined based on daily routine types. A total 23 classes' activity times and teacher behaviors were observed. The collected data were analyzed using descriptive statistics, hierarchical cluster, and Mann-Whitney U. Results indicated that there were 2 principle daily routine, 'indoor/outdoor activity time oriented' and 'group activity time oriented'. Analysis showed that teachers who belonged to the 'indoor/outdoor activity time oriented' type showed more positive affect, positive guidance, neural guidance, and less non-involved behavior. Results suggest the importance of time spent on free choice activities in the context of daily routine for quality childcare.

This study compared the nutrient intake of obese versus non-obese non-insulin dependent diabetes mellitus (NIDDM) patients for Diabetes Medical Nutrition Therapy. The study was conducted at medical hospitals in Gyeonggi and Seoul from April 2009 to November 2009. Fifty-six adult male NIDDM patients were enrolled and divided into two groups: 36 into an obese group (BMI ${\geq}25$) and 20 into a non-obese group (BMI<25). To conduct this study, anthropometric measurements, and daily nutrient intake of obese and non-obese NIDDM patients were measured. Daily nutrient intake was estimated by 24hr-recall and analyzed by the CAN program. In the results, anthropometric measurements of the two groups showed significant differences in weight and BMI (p<0.001). Daily nutrient intake of the two groups showed no significant differences, except for vitamin E intake (p<0.05). The total energy intake of the non-obese and obese groups were $2,669.9{\pm}964$ kcal and $2,555.4{\pm}803$ kcal, respectively, which were both above 113% of the recommended Dietary Reference Intakes for Korean (KDRIs). Cholesterol and sodium intake were $378.1{\pm}215.6$ mg and $6,478.9{\pm}2755.1$ mg, respectively for the non-obese group. Cholesterol and sodium intake were $308.1{\pm}155.6$ mg and $6,306.8{\pm}2788.9$ mg, respectively, for the obese group. Both groups were above 150% of the recommended levels set by the Korean Diabetes Association (KDA). However, their antioxidant nutrient intake was appropriate. Meanwhile, their fiber intake was $10.7{\pm}5.1$ g and $9.8{\pm}5.2$ g, respectively, which was lower than 40% of the recommended intake set by the KDA. The results show that the nutritional education for obese and non-obese NIDDM male patients must aim to reduce total energy, cholesterol, and sodium intake, while increasing fiber intake. In addition, the factors related to a patient's glycosylated hemoglobin, serum lipids, blood pressure, and weight change must be calibrated for the appropriate energy, fat, cholesterol, sodium, and dietary fiber intake.

The rapid aging is increasing as the shortage of medical facilities and the resulting of decline in the quality of public health. In order to ease the burden of rising medical expenses, advanced medical institutions are expanding their remote medical care to lower the cost of services. U-healthcare detects the changes in physical and chemical phenomena occurring in the human body and converts them into electrical signals that can be processed and feeds back to the results through analytical and visualization processes to select only the desired information from the measured signals. The service is provided through a process of providing an alarm to a user. However, traditional biometric methods of attaching sensors directly to the body can be annoying and rejected in daily life. Therefore, there is a need for a method of continuously measuring biometric information without causing inconvenience to daily life. In this paper, we propose an IR-UWB-based non-contact and non-responsive respiratory measurement system that can continuously monitor biological information without any inconveniences to daily life.

Daily milk yields on test days were estimated using morning or afternoon partial milk yields collected by official agencies and the accuracy of the estimates was determined. Test-day data for milk yields consisted of 3,156,734 records of AM/PM partial milking measurements of 255,437 milking Holstein cows from 3,708 farms collected from December 2008 to April 2013. A linear regression model (LRM) was applied to estimate daily milk yields using alternate AM/PM milk yield records within lactation stages, milking intervals, and parities on every daily milk yield. The alternate statistical approach was a non-linear hierarchical model (NHM) in which Brody's growth function was implemented by reflecting an animal's physiological milk production cycle. When compared with LRM, daily milk yields predicted by the NHM were assumed to be functionally related to day in milk (or lactation) stage, milking intervals, and partial milk yields. Since the results were in terms of accuracies based on comparisons of different statistical models, accuracies of estimates of daily milk yields by NHM were close to those determined by the LRM. The average of these accuracies was 0.94 for AM partial milk yields and 0.93 for PM partial milk yields for first calving cows. However, the accuracies of AM/PM milk yield estimations from cows under a calving stage higher than the first parity were 0.96 and 0.95, respectively. Correlations between the estimated daily milk yields and the actual daily milk yields ranged from 0.96~0.98. These accuracies were lower for unbalanced AM/PM milking intervals and the first calving cows. Overall, prediction of daily milk yields by NHM would be more appropriate than by LRM due to its flexibility under different milk yield-related circumstances, which provides an idea of the functional relationship between milking intervals and days in milk with daily milk yields from statistical viewpoints.

This study was intended to investigate the effect on the human body such as subcutaneous fat thickness the circumference of extremities etc. of the clothing training of putting on thin clothes periodically from the cold period. The subjects were divided into the clothing training group and the non-training group, The training group was asked to wear cool clothes in daily life and to wear the training clothes of T-shirts with half-length sleeves and pants and perform the clothing training for two hours daily three times a week in a cold environment over the period from November to February. The non-training group was asked to lead a life wearing comfortable clothes. Then a comparative experiment was conducted at 15$\pm$1$^{\circ}C$, 50$\pm$5% R, H and 0.25m/sec before and after the clothing training. After the clothing training regardless of gender subcutaneous fat thickness was more increased and total clothing weight per the surface area of the body was decreased in the training group than the non-training group. The training group showed lower skin temperature in the limbs and lower average skin temperature than the non-training group irrespective of gender which proved the effect of the clothing training. The training group was shown to have attendancy toward a greater sense of warmth and a less sense of discomfort which proved the effect of the clothing training.

Background: Lung cancer is the most common cancer in males worldwide. The principal mode of treatment in the early stage of non-small cell lung cancer (NSCLC) is surgery. However, five-year survival is only about 15% for all stages. The aim is to investigate the effect of daily low dose cisplatin concurrently with radiation therapy in advanced NSCLC patients with poor performance status. Materials and Methods: Ten patients diagnosed as inoperable Stage IIIB NSCLC with comorbid disease were assessed retrospectively in Bezmialem Vakif University, Faculty of Medicine, Department of Radiation Oncology, between 2011 to 2013. ECOG performance status was between 3 and 4. Cisplatin was administered at $6mg/m^2$ daily, for 5 days a week concurrently with radiotherapy using 160-200 cGy daily fractions, 54 Gy being the lowest and 63 Gy being the highest dose. Results: Complete response at the primary tumour site was obtained in 20% patients. Grade I esophagitis was seen 70 percent of patients, and the grade II haematological toxicity rate was 20 %. Median survival time was 7 months. Conclusions: Median survival time was reasonable, despite the patients ECOG performance status of 3-4, which is similar to groups even without comorbid disorders in comparison to other published papers in the literature. Acceptable toxicity, high response rates and quality of life of patients are the other favourable features.

This study investigated the effects of nursing in formation given verbally and a booklet on the knowledge, Physical symptoms, anxiety and daily activities of patients recovering from open heart surgery from just before discharge to six weeks after discharge. The convenience sample was of patients who had undergone open heart surgery in Seoul National University Hospital. The first 25 patients who agreed to participate in the study became the control group. They did not receive the intentional information but the usual nursing care. The next 28 patients became the experimental group who received a booklet about their post-discharge care which was discussed with them by the researcher before discharge. This study used a non equivalent control group non - synchronized quasiexperimental design. The tools included a 30 item knowledge scale, a 9 item physical symptom scale, Spielberger's state anxiety scale, and a 28 item daily activity scale. The instruments were applied before discharge and at two and six weeks after discharge. For data analysis, frequency, t-test, Pearson's Correlational Coefficient and Cronbach's $\alpha$ were used. The results were as follows : 1. Information given through the booklet was effective in increasing the knowledge of patients recovering from open heart surgery. The experimental group's knowledge was higher at 2 weeks after discharge than prior to discharge (P＜0.05). 2. There was no significant difference in physical symptoms between the two groups at two and six weeks after discharge. 3. Information given through the booklet was effective in decreasing the State Anxiety two weeks after discharge (P＜0.001) but at six weeks after discharge, there was no significant difference in anxiety between the control and the experimental groups. 4. There was no significant difference in daily activity between the two groups at two and six weeks after discharge. 5. There was a negative correlation between knowledge at discharge and at 2 weeks and anxiety at 2 weeks after discharge. There was a positive correlation between knowledge at discharge and daily activity at 2 weeks after discharge. There was a negative correlation between knowledge at 2 weeks and Physical symptom at 6 weeks after discharge.
