Shutdown chemistry evolution is performed in nuclear power plants at each refueling outage (RFO) to establish safe conditions to open system and minimize inventory of corrosion products in the reactor coolant system (RCS). After hydrogen peroxide is added to RCS during shutdown chemistry evolution, corrosion products are released and are removed by filters and ion exchange resins in the chemical volume control system (CVCS). Shutdown chemistry evolution including RCS clean-up time to remove released corrosion products impacts the critical path schedule during RFOs. The estimation of clean-up time prior to RFO can provide more reliable actions for RCS clean-up operations and transients to operators during shutdown chemistry. Electric Power Research Institute (EPRI) shutdown calculator (SDC) enables to provide clean-up time by Co-58 peak activity through operational data from nuclear power plants (NPPs). In this study, we have investigated the results of EPRI SDC by shutdown chemistry data of Co-58 activity using NPP data from previous cycles and modeled the estimated clean-up time by EPRI SDC using average Co-58 activity of the NPP. We selected two RFO data from the NPP to evaluate EPRI SDC results using the purification time to reach to 1.3 mCi/cc of Co-58 after hydrogen peroxide addition. Comparing two RFO data, the similar purification time between actual and computed data by EPRI SDC, 0.92 and 1.74 h respectively, was observed with the deviation of 3.7-7.2%. As the modeling the estimated clean-up time, we calculated average Co-58 peak concentration for normal cycles after cycle 10 and applied two-sigma (2σ, 95.4%) for predicted Co-58 peak concentration as upper and lower values compared to the average data. For the verification of modeling, shutdown chemistry data for RFO 17 was used. Predicted RCS clean-up time with lower and upper values was between 21.05 and 27.58 h, and clean-up time for RFO 17 was 24.75 h, within the predicted time band. Therefore, our calculated modeling band was validated. This approach can be identified that the advantage of the modeling for clean-up time with SDC is that the primary prediction of shutdown chemistry plans can be performed more reliably during shutdown chemistry. This research can contribute to improving the efficiency and safety of shutdown chemistry evolution in nuclear power plants.

Dental surgical procedures are potentially stress-inducing to not only patients but clinicians especially in case of medically compromised patients. The body response to dental stress involves the cardiovascular, respiratory and the endocrine system. To minimize the stress to the medically compromised patients, the stress reduction protocols should be established. The protocols include (1) Recognize the patient's degree of medical risk (2) Medical consultation before dental therapy (3) Schedule the patient's appointment in the morning (4) Monitor and record preoperative, perioperative and postoperative vital signs (5) Intra-venous sedation during surgical procedures (6) Adequate pain control during therapy (7) Short length of appointment time (8) Contact the patients on the same day. Two cases of Bisphosphonate-related osteonecrosis of the jaws were analyzed. There were 2 women, and the mean age was 70 years (range, 64~74 years). both are medically compromised, with steroids. Both patients were taking an oral bisphosphonate for several years. BRONJ is defined as an area of exposed bone of more than 8 weeks - duration in a patient taking a bisphosphonate for bone disease. Bisphosphonates have been widely prescribed over the last decade for a range of bone diseases, mainly intravenously for bone cancers and orally for osteoporosis. Although it is still controversial as to precisely how the bisphosphonates work, generally it is accepted that they prevent osteoclast action, with consequent cessation of osteoblast activity, so that the bone turnover is markedly reduced or ceased. The aim of this study is to informed the clinicians how to prepare and recognize in case of the BRONJ with medically compromised patients.

Purpose: The purpose of this study was to investigate level of functioning in patients with stroke using Modified Bathel Index (MBI), World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0), and ICF core-set for stroke. Methods: Sixty-four patients with stroke were recruited for this study from nine medical institutes. The ICF core-set for stroke, WHODAS 2.0, and MBI were used to collect subjects' functional levels. ICF core-set was employed here as a standard frame to observe multi-dimension of functioning, that is physiological bodily function, activity and participation (AP) in daily life, and current environmental factors (EF) in patients with stroke. WHODAS 2.0 and MBI were also used in order to have a specific functioning level for subjects. The linkage of each item in WHODAS 2.0 and MBI into the ICF core-set for stroke was examined. Pearson correlation coefficient was used for analysis of their relationships. Results: Functioning level of participants showed moderate resulting from MBI and WHODAS 2.0 ($73.48{\pm}22.27$ and $35.55{\pm}12.53$, respectively). Strong relationship was observed between ICF core-set and WHODAS 2.0, and with MBI. Each item of disability scales was obtained its linkage into ICF in the domain of AP. However, lack of correlation between MBI and ICF in the domain of EF was found due to absence of related factors. Conclusion: MBI was found to be linked mainly into ICF in the domain of AP and to have limited linkage into EF. Therefore, it should be suggested that the ICF concept frame should be used as a multi-dimensional approach to patients with stroke.

Background : A critical path defines an optimal sequencing and timing of interventions by physicians, nurses, and other staff for a particular diagnosis or procedure, designed to better utilize resources, maximize quality of care, and minimize delays. It can be thought of as a visualization of the patient care process. In this study, a review of appendectomy patient records was undertaken to identify a critical path for the management of this treatment. Methods: For this study, records of patients under 15 or over 65 years of age were excluded ; cases where the patient was pregnant, or where complications developed were also excluded. The remaining 21 cases were divided into two categories according to the indication for appendectomy : for acute appendicitis, and for perforated appendix or drainage of periappendical abscess. The time frame for the review was from patient examination immediately prior to operation, through discharge. The study team was composed of a surgeon, research head nurse, education head nurse, surgical part head nurse, and medical recorder. Following their review of the 21 charts, the team determined an appropriate progression and schedule for an appendectomy. Result : Through the chart and literature review, the following aspects of the care process were identified as typical and tracked : monitoring/assessment, treatment, lines/drains, medication, activity, diet, tests and patient education. Conclusion : From this study, the design team determined two separate critical paths : one for appendectomy only, and one for appendectomy plus drainage. Next, these paths must be validated and fine-tuned through clinical implementation. In addition, a comparison of our design with the critical paths determined at other hospitals would be extremely valuable for advancing research in this area. Lastly, the critical path approach to improving patient care and maximizing hospital resources should be applied to other procedures.

It is an important task to give adequate nutritions to infants and to wean properly for rapid growth. This study was conducted to survey on doing the weaning activities of the first-time mother. This study was to provide basic data of health teaching and nursing intervention for the promotion of ideal weaning activities. Survey was done from January to February in 2001. Total 444 mothers who have first-time baby under twelve month old were interviewed in five community health center around contry (Seoul, Choung-ju, Asan, Cheon-an, Jeju). The results are summarized as follows; Starting time of weaning was common in four month old(40.4%). Most common daily weaning times by age showed once(under 3 months), twice(4 to 7 months), three times(8 to 12 months). The younger, the more commercial weaning products(p<0.01). Education level showed relatively positive relation with home-made weaning food(p<0.05). Items showed low scores in 4 to 7 months group were starting new food item, waiting at least one week interval to new food, feeding by milk bottle, allowing grasping spoon, consulting pediatrician for problems after weaning, starting from morning, regular schedule. Items showed low scores in 8 to 12 months group were feeding whole egg rather than yolk only up to 12 months, keeping weaning interval were increased, feeding by milk bottle, trying various cooking method, not giving commerical cooking and instant food and unproper raw milk feeding. In weaning activities by general factors, mother age, health status, marriage duration, monthly income were statistically significant (p<0.05). To improve good weening activities, targetting on low maternal age and poor health status, and low income group, developing teaching materials and training program for items showed low scores and proper weaning time, type of easy home-made food and easy cooking method should be provided. Further study on effect of nursing intervention to improve weaning activities are needed.

The e-CALLISTO is a network of CALLISTO (Compact Astronomical Low-frequency, Low-cost Instrument for Spectroscopy in Transportable Observatories) spectrometers which detect solar radio bursts 24 hours a day in frequency range 45-870 MHz. The number of channels per spectrum is 200 and the time resolution of whole spectrum is 0.25 second. The Korean e-CALLISTO station was developed by Korea Astronomy and Space Science Institute (KASI) collaborating with Swiss Federal Institute of Technology Zurich (ETH Zurich) since 2007. In this paper, we report replacement of the tracking mount and development of the control program using Visual C++/MFC. The program can make the tracking mount track the Sun and schedule CALLISTO to start and to finish its observation automatically using the Solar Position Algorithm (SPA). Daily tracking errors (RMSE) are 0.0028 degree in azimuthal axis and 0.0019 degree in elevational axis between 2014 January and 2015 July. We expect that the program can save time and labor to make the observations of solar activity for space weather monitoring, and improve CALLISTO data quality due to the stable and precise tracking methods.

Risk management activity for successful defense R&D project should be done anticipatorily and consistently over the entire project period and there should be a priority for management depending on importance of the risk factors. In this study, we verified the reliability and validity through factor analysis for the risk factors selected by the Delphi technique. We also obtained the relative importance of risk factors with analytic hierarchy process (AHP) and decided to prioritize for comparison of domestic and overseas research. According to the study, we found that it is important to settle the requirements and to classify the scope of R&D. It is also considered significant to have reasonable schedule for completion and secure the necessary resources in the early stage of project. Unlike previous studies, it appeared the technical factors are critical elements as well for defense R&D project.

We investigated the antihypertensive effect of Pet ether extract (PE) of ginger rhizome; its toluene fraction (TF) and Korean ginseng extract (KGE) in deoxycorticosterone acetate (DOCA) - salt induced and fructose induced hypertensive rats. In DOCA model, DOCA (25 mg/kg, once a week; s.c) was administered in uninephrectomised animals for 4 w. PE (50 mg/kg/day; p.o), TF (10 mg/kg/day; p.o) and KGE (30 mg/kg/day; p.o) were evaluated for their antihypertensive effect. In the fructose model, drinking water was replaced with fructose (10%) for five weeks to induce hypertension. PE (50 mg/kg/day; p.o) and KGE (30 mg/kg/day; p.o) were assessed for its antihypertensive effect in fructose model. After completion of the treatment schedule, vascular reactivity to various agonists like 5-HT, noradrenaline, adrenaline, phenylbiguanide and acetylcholine were recorded in rats of both the models. A cumulative dose response curve (CDRC) of 5-HT was carried out in isolated rat fundus strip of the fructose induced hypertensive rats. Chronic administration of PE (50 mg/kg/day; p.o), TF (10 mg/kg/day; p.o), and KGE (30 mg/kg/day; p.o) significantly reduced the blood pressure in DOCA salt whereas PE (50 mg/kg/day; p.o) and KGE (30 mg/kg/day; p.o) reduced the blood pressure in fructose induced hypertensive rats. Treatment with PE (50 mg/kg/day; p.o) and KGE (30 mg/kg/day; p.o) in fructose model for five weeks shifted the CDRC towards the right on rat fundus. The mechanism of action may partly involve the serotonergic antagonistic property.
