PURPOSE: This descriptive study was done to identify factors that influence stress related to clinical practice for nursing students. METHODS: Structured questionnaires were used to collect data from 278 students from two nursing colleges located in G metropolitan city and one nursing college in C region. RESULTS: The factors that most influenced stress for the nursing students during their clinical practice were critical thinking disposition, clinical competence, year, and gender. Especially, the result showed that higher critical thinking disposition and clinical competence correlated with lower stress in clinical practice. CONCLUSION: The results indicate that improving nursing students' critical thinking ability and clinical competence would help to relieve stress during clinical practice and increase the ability to cope with stress efficiently. The development of a variety of teaching and learning strategies and education in both theoretical and clinical practice education would be necessary to achieve this goal.

PURPOSE: This study was conducted to determine whether low intensity regular exercise following dexamethasone treatment could attenuate steroid-induced muscle atrophy. METHOD: 36 Wistar-rats(90-110g) were divided into six groups: control group(C), dexamethasone treatment group(D), sedentary group after normal sedentary period(C+S), sedentary group after dexamethasone treatment period(D+S), exercise group after normal sedentary period(C+E), and excercise group after dexamethasone treatment period(D+E). D, D+S, and D+E groups received dexamethasone injection(5mg/Kg) for seven days whereas C, C+S, and C+E groups received normal saline injection. Both C+E and D+E groups ran on a treadmill for 60 minutes/day(20minutes/4hours) at 15m/min and a 10degreegrade for seven recovery days. RESULT: Post-weight(body weight before muscle dissection) of D group significantly decreased by 16.03%, and that of D+E group significantly increased by 15.51% compared with pre-weight(body weight before steroid treatment). Type II muscle(plantaris and gastrocnemius) weights of D group were significantly lower than those of C group. Myofibrillar protein contents of type II muscles of D group tended to decrease comparing with C group. In D+E groups, body weights and relative weights of typeII muscles(muscle weight(mg)/post-weight(g)) tended to increase comparing with D+S group. CONCLUSION: It is suggested that steroid- induced muscle atrophy can be ameliorated through low intensity regular exercise after dexamethasone treatment.

PURPOSE: The purpose of this study was to examine the effects of cerebral ischemia on Type I(soleus) and Type II(plantaris, gastrocnemius) muscles, and to determine the effects of isometric contraction training by electrostimulation on Type I andII muscles in cerebral ischemia model rats. METHOD: Twenty-five male Sprague-Dawley rats were randomly divided into four groups: ST(stroke), STES(stroke+electrostimulation), SH(sham) and SHES (sham+electrostimulation). The ST and STES groups received a transient right middle cerebral artery occlusion operation. The SH and SHES groups received a sham operation. The STES and SHES groups had daily isometric contraction training by electrostimulation(100Hz, 45mA, 7.5V) on hindlimb muscles for 7days. RESULT: Plantaris and gastrocenmius muscle weight, myofibrillar protein contents of soleus and gastrocnemius, and the muscle fiber cross-sectional area of gastrocnemius in the ST group significantly decreased compared with the SH group. Soleus, plantaris, gastrocnemius muscle weight, myofibrillar protein contents of soleus and gastrocnemius, and the Type I muscle fiber cross-sectional area of soleus and the Type II muscle fiber cross-sectional area of gastrocnemius in the STES group significantly increased compared with the ST group. CONCLUSION: Hindlimb muscle atrophy occurs after acute stroke and isometric contraction training by electrostimulation during early stages of a stroke attenuates muscle atrophy of Type I and Type II muscles.

The purpose of this study was to elucidate effects of fructooligosaccharide on gastrointestinal tract and blood lipids of rats when this was supplied as purchased condition or oligosaccharide containing sponge cake. Male Sprague-Dawley rats were assigned to one of 3 treatments 1) control diet 2) 7.5% fructooligosaccharide containing diet (FOS diet) 3) lyophilized sponge cake powder containing diet (FOS-C diet). The sponge cake was made with fractooligosaccharide which replaced 40% of its surose, and the final concentration of fructooligosaccharide in FOS-C diet was 7.5%. Cecal and fecal water contents, amount of cecal content, and cecal wall weight were higher from fructooligosaccharide consumption, whereas total gut transit time was longer in rats consuming fructooligosaccharide compared with those fed control diet. Cecal and fecal pH were lower in FOS and FOS-C groups than in control group. Total cecal SCFA pools were higher from ingesting fructooligosaccharide containing diets compared with control diet. Serum triglyceride levels were lower in rats fed FOS and FOS-C diet than those fed control diet, while serum cholesterol levels were unaffected by treatment. Therefore the effects of fructooligosaccharide in sponge cake on serum lipids and gastrointestinal tract were similar to those of intact fructooligosaccharide. Also, adding 7.5% of FOS accompanied diarrhea symptom which suggests some precaution are needed when using FOS.

BACKGROUND/AIMS: Metal stent insertion through percutaneous transhepatic biliary drainage (PTBD) track is an important palliative treatment modality for malignant biliary obstruction. Acute pancreatitis is one of serious complications of biliary metal stenting. The purpose of this study was to investigate the risk of pancreatitis for patients who underwent metal stent insertion via PTBD track. METHODS: A retrospective analysis of 90 consecutive patients who received metal stent insertion via PTBD track from Jan. 2002 to Dec. 2007 was carried out. Patients were devided into the transpapillary and non-transpapillary group, and the risks of pancreatitis were compared. The effects of preliminary endoscopic sphincterectomy (EST) was also investigated in transpapillary group. RESULTS: The rate of pancreatitis was higher in transpapillary group compared to nontranspapillary group (odd ratio 1.87, 95% CI 0.516-6.761), but it showed no stastically significance (p=0.502). In transpapillary group, patients who received preliminary EST showed lower rate of pancreatitis (odd ratio 0.91, 95% CI 0.656-1.273), but it showed no stastically significance (p=0.614). CONCLUSIONS: Metallic stent insertion through the intact sphincter of Oddi might have a risk of developing pancreatitis. Further study is needed to elucidate the mechanism of pancreatitis and the way of prevention.

BACKGROUND: The purpose of this study was to survey the nasal colonization of methicillin-resistant Staphylococcus aureus (MRSA) among the patients admitted in a medical intensive care unit (MICU) and analyze risk factors associated with the colonization. METHODS: The study was carried out on patients admitted into the MICU in a 1,250-bed tertiary care university hospital from January through December 2006. Nasal surveillance cultures were obtained from patients within 24 hours of admission to the unit. Data were analyzed retrospectively by the review of medical records. RESULTS: A total of 312 patients were screened with active nasal cultures; 36 patients (11.6%) were positive for MRSA. Of these, 22 (7.1%) were positive in the nasal cultures only and 14 (4.5%) were positive in the cultures of other specimens (13, sputum; 1, joint fluid) in addition to the nasal swabs. Among the risk factors for MRSA nasal colonization were sex (man), route of admission (from other ICUs or wards), a history of ICU admission during the recent 12 months, and prolonged hospital days in ICU. CONCLUSION: MRSA nasal carrier rate was found higher in this study than in those reported in the literature. Most of the patients colonized with MRSA in the nostril were not colonized with the organism elsewhere in the body. Whether or not active surveillance for MRSA should be performed would depend on the nasal colonization rate of the patients at the time of admission to the ICU.

Objectives: This study was conducted to create a 3D printable snack dish model for the elderly with low food or fluid intake along with barriers towards eating. Methods: The decision was made by the hybrid-brainstorming method for creating the 3D model. Experts were assigned based on their professional areas such as clinical nutrition, food hygiene and chemical safety for the creation process. After serial feedback processes, the grape shape was suggested as the final model. After various concept sketching and making clay models, 3D-printing technology was applied to produce a prototype. Results: 3D design modeling process was conducted by SolidWorks program. After considering Dietary reference intakes for Koreans (KDRIs) and other survey data, appropriate supplementary water serving volume was decided as 285 mL which meets 30% of Adequate intake. To consider printing output conditions, this model has six grapes in one bunch with a safety lid. The FDM printer and PLA filaments were used for food hygiene and safety. To stimulate cognitive functions and interests of eating, numbers one to six was engraved on the lid of the final 3D model. Conclusions The newly-developed 3D model was designed to increase intakes of nutrients and water in the elderly with dementia during snack time. Since dementia patients often forget to eat, engraving numbers on the grapes was conducted to stimulate cognitive function related to the swallowing and chewing process. We suggest that investigations on the types of foods or fluids are needed in the developed 3D model snack dish for future studies.

OBJECTIVES: Age-related differences of the brain have been obtained by various methods. This study was aimed to explore the changes of quantitative electroencephalography (qEEG) and their source localization in normal aging. METHODS: Thirty-seven healthy young adults (mean age 35.22+/-13.62 years) and thirty-nine cognitively-healthy elderly subjects (mean age 72.95+/-5.73 years) participated in the study. Resting-state EEGs were recorded while subjects were in a relaxed state. Relative qEEG powers of five frequency bands were analyzed for eye closed conditions: delta (1-3 Hz), theta (4-7 Hz), alpha (8-12 Hz), beta (13-25 Hz), and gamma (30-50 Hz). The standardized low resolution electromagnetic tomography (sLORETA) was used to identify the current source densities of each frequency band. RESULTS: The elderly group showed an increase of beta and gamma power while the reduction of delta, theta, and alpha power compared with the young group. Controlling education as a covariate, the beta power was positively correlated with age, while theta power was negatively correlated with age in all subjects. sLORETA revealed that elderly subjects had reduced current source density at the cingulate gyrus in the theta band, while increased current source densities at the frontal, parietal, insula, and limbic areas in the beta band compared with young adults. CONCLUSION: Our results suggested that qEEG could reflect normal aging. Cognitively healthy elderly subjects showed an increase of high-frequency power, while showing a reduction of low-frequency power. These functional implications were discussed.

Background/Aims: The Korean Diabetes Association (KDA) guidelines recommend adults aged ≥ 40 years and adults aged ≥ 30 years with diabetes risk factors for diabetes screening. This study aimed to determine the age threshold for diabetes screening in Korean adults. Methods: This study was based on the analyses of Korean adults aged ≥ 20 years using the Korea National Health and Nutrition Examination Survey (KNHANES) and the National Health Insurance Service-National Sample Cohort (NHIS-NSC). To evaluate screening effectiveness, we calculated the number needed to screen (NNS). Results: NNS to detect diabetes decreased from 63 to 34 in the KNHANES and from 71 to 42 in the NHIS-NSC between the ages of 30–34 and 35–39. When universal screening was applied to adults aged ≥ 35, the NNS was similar to that of adults aged ≥ 40. Compared to the KDA guidelines, the rate of missed screening positive in adults aged ≥ 20 decreased from 4.0% to 0.2% when the newly suggested screening criteria were applied. Conclusions Universal screening for adults aged ≥ 35 and selective screening for adults aged 20 to 34, considering diabetes risk factors, may be appropriate for detecting prediabetes and diabetes in South Korea.
