To prevent the secondary hospital-acquired infection (cross-infection) from occurring in the general radiographic room in the department of radiology, the microbial measurement was conducted at the points making direct close contact with radiologists and patients. For the case of radiologists, the microbial measurement and incubation were focused on the x-ray tube handle of the radiation generating device, and, for the case of patients, the microbial measurement and incubation were focused on the chin supporting device, chest-contact point, and handle. Once disinfected with Aniosurf, the sterilized media were gathered and identified, and the microorganisms were confirmed. Based on the identification results, it was confirmed that the points making direct close contact with radiologists showed a value of 103 CFU for Proteus mirabilis, Staphylococcus epidermidis, Bacillus spp. and Candida spp., and that the points making direct close contact with patients showed a value of 103~5 CFU for Proteus mirabilis, Enterococcu faecium, Pseudomonas aeruginosa, NTM(Non-Tuberculosis Mycobacteria) and Candida spp.. It was also confirmed that the types and number of microorganisms gathered from the points making direct close contact with patients were greater. Fortunately, most of the involved microorganisms were observed to be on the skin surface and are known to become extinct when disinfected in accordance with the hospital-acquired infection control rules. However, since even minor exposure to such microorganisms may be lethal for patients with reduced immunity, caution must be taken. In particular, since the points making contact with patients showed a high level of microbial measurement, it was thought that it would be necessary for radiologists and personnel having frequent access to strictly disinfect the parts, such as instruments and handles, making frequent contact with patients. The purpose of this study was to announce the importance of safe microbial control in the radiographic inspection room in hospital, and this study is expected to be used as the baseline data for preventing hospital-acquired secondary infection and Nth infectious diseases.

Benzodiazepines (BDZs) drugs act on the GABA_A receptor, function as nerve suppressors, and are used to treat anxiety, insomnia, and panic disorder. We analyzed the data of 30 individuals to determine any differences in the sleep-electroencephalogram findings among individuals varying in age, benzodiazepine use, and duration of benzodiazepine use. Comparisons between users and non-users of benzodiazepines, short-term and long-term users, older and younger users, and older short-term and older long-term users, were achieved using electroencephalographic findings obtained through polysomnography. The parameters evaluated included sleep latency, sleep efficiency, sleep-stage percentages, number of sleep spindles, and average frequency of sleep-spindle. The difference between benzodiazepine users and non-users was significant with respect to sleep-stage percentages and average frequency of sleep-spindle. Older and younger users differed significantly with respect to sleep efficiency and sleep-stage percentages, whereas significant difference for sleep efficiency was obtained between long-term and short-term users. Taken together, our results indicate that BDZ consumption suppresses slow-wave sleep and increases the frequency of sleep spindles.

A number of studies have been conducted to prevent obesity due to the worldwide increasing rate of obesity and its adverse effects on our health. Recently, a relationship between obesity and gut microbiome has been reported. Fecal and cecal microbiota are generally targeted for examining the gut microbiome during dietary interventions. There is, however, no common understanding on which microbiota and how results elucidated from the data would differ. In this study, we conducted dietary induced obesity study and compared fecal and cecal microbiota affected by dietary interventions. Normal Diet and high fat diet were fed to 6 weeks old mice for 12 weeks, and 16 S rRNA genes amplified from fecal and cecal DNA were sequenced using MiSeq. Our results show that the 𝛼-diversity showed significant differences between the dietary interventions as well as cecal and fecal microbiota. The difference in the taxonomic compositions between cecal and fecal microbiota had become clearer at the family and genus level. At the genus level, Faecalibaculum and Lactobacillus were more abundant in the cecal and fecal microbiota, respectively. In general dietary intervention studies, dietary effects are more significant than type difference. However, the microbiota analysis results should be interpreted carefully, considering both diet and samples (feces/caecum).

Sarcopenia, a common clinical syndrome in older adults, is defined as decreased muscle mass, strength, and physical performance. Since sarcopenia is associated with the incidence of functional decline, falls, and even mortality in older adults, researchers and health care providers have been keen to accumulate clinical evidence to advocate the screening and prevention of sarcopenia progression in older adults. The factors that may accelerate the loss of muscle mass and function include chronic diseases, inactivity, and deficiency in appropriate nutritional support. Among these, nutritional support is considered an initial step to delay the progression of muscle wasting and improve physical performance in community-dwelling older adults. However, a nationwide study suggested that most Korean older adults do not consume sufficient dietary protein to maintain their muscle mass. Furthermore, considering age-associated anabolic resistance to dietary protein, higher protein intake should be emphasized in older adults than in younger people. To develop a dietary protein recommendation for older adults in Korea, we reviewed the relevant literature, including interventional studies from Korea. From these, we recommend that older adults consume at least 1.2 g of protein per kg of body weight per day (g/kg/day) to delay the progression of muscle wasting. The amount we recommend (1.2 g/kg/day) is 31.4% higher than the previously suggested recommended daily allowance (i.e., 0.91 g/kg/day) for the general population of Korea. Also, evidence to date suggests that the combination of exercise and nutritional support may enhance the beneficial effects of protein intake in older adults in Korea. We found that the current studies are insufficient to build population-based guidelines for older adults, and we call for further researches in Korea.

Background/Aims: The primary aims of this study were to evaluate the content quality of YouTube videos on exercises to help relieve constipation and to assess whether the video source, exercise types, and popularity affected their quality. Methods: Eight gastroenterologists independently evaluated the exercises presented in the constipation YouTube videos for seven items: image quality, usefulness in relieving constipation (quality 1), usefulness for general physical health (quality 2), difficulty in following, activity intensity, fun, and overall quality. Raters were asked open-ended questions to evaluate the strengths and weaknesses of the videos. Five-point ordinal scales were used to score each item aforementioned, with the exception of image quality and overall quality that used a six-point Likert scale. Results: The 20 videos had a mean length of 268 seconds and a mean viewership of 32,694. The most common video source was commercial (n=10), and the most common type of physical activity was yoga (n=11). The median values of image quality, quality 1, quality 2, difficulty in following, activity intensity, fun, and overall quality were 3, 2, 2, 2, 2, 2, and 2, respectively. Yoga videos had significantly higher median quality 1 values (3) compared with massage videos (2, adjusted p=0.006) and 'others' videos (2, adjusted p<0.001). A lack of medical evidence was the most common answer to open-ended questions about the weaknesses of each video. Conclusions: Overall, YouTube exercise videos presented a low-quality content. This study highlights the need for evidence-based comprehensive educational videos addressing exercises for treating constipation.

Purpose: Sentinel lymph node (SLN) biopsy (SLNB) is widely accepted for staging of melanoma patients. It has been shown that clinico-pathological features such as Breslow thickness, ulceration, age, and sex are better predictors of relapse and survival than SLN status alone. The aims of this study were to evaluate the long-term (10-year) prognostic impact of SLNB and to determine predictive factors associated with SLN metastasis, relapse, and melanoma specific mortality (MSM). Methods: This was a prospective observational study on 289 consecutive patients with primary cutaneous melanoma who underwent SLNB from January 2000 to December 2007, and followed until January 2014, at an Italian academic hospital. Results: SLN was positive in 64 patients (22.1%). The median follow-up was 116 months (79-147 months). Tenyear disease-free survival and melanoma specific survival were poor in patients with positive SLN (58.7% and 66.4%, respectively). Only the increasing Breslow thickness resulted independently associated to an increased risk of SLN metastasis. Cox regression analysis showed that a Breslow thickness >2 mm was an independent predictor of relapse, and male sex and Breslow thickness >2 mm was a predictor of MSM. At 10 years, SLN metastasis was not significantly associated to either relapse or MSM. Conclusion: After the fifth year of follow-up, SLN metastasis is not an independent predictive factor of relapse or mortality which are mainly influenced by the characteristics of the primary tumor and of the patient. Patients with a Breslow thickness >2 mm regardless of the SLN status should be considered at high risk for 10-year relapse and mortality.

The purpose of this study was to examine the current status of the Dream Start program from the perspective of social investment strategy, and as well as to suggest future directions. The program has become a major government welfare program in korea since it was introduced in 2007 as a demonstration project, following research evidence and a sound rationale about the extensive success of Head Start in the U.S. and Sure Start Programme in the UK. The aim of Dream Start is to provide integrated services for the vulnerable children, aged 0 to 12, and their families who are identified using a national administration data record of disadvantaged families with children. In order to promote the vulnerable child's well-being, to overcome inequalities, and to give every child the best start in life, Dream Start adopted a local, "whole family" approach. Case management services form an essential part of the Dream Start to customize and integrate comprehensive services such as counseling, health care, parenting advice and education, academic tutoring, and after-school activities. Although there has been a general improvement in key factors since its inception, Dream Start has not yet sufficiently shown the strong and hoped-for impact. In the meantime, Dream Start must be given financial expansion and extensive policy supports to get the chance of realizing and evaluating long-term gains for children and their families. More work need to be done to overcome inequalities and to make Dream Start service more accessible for the most disadvantaged families with children in Korea. Practical and policy suggestions for future directions of the Dream Start programs were discussed.

The purpose of this study was to examine the relationship between the working posture and symptoms of musculoskeletal disorders of dental hygienists during scaling. The subjects in this study were 264 selected dental hygienists. A convergence study was implemented using questionnaire that was prepared to cover general characteristics, health care, the work of scaling, working posture and subjective musculoskeletal symptoms. As for data analysis, R 2.15.1 was employed. As a result of analyzing the collected data, the rate of good working posture during scaling stood at 29.9 percent; roughly good posture, at 37.5 percent; incorrect posture, at 32.6 percent. Regarding the area of the body in which they complained of musculoskeletal symptoms, the shoulders were 3.32-fold more mentioned than any other area(OR,3.32;95%CI, 1.58~6.98); the foot, 2.97-fold more(OR,2.97;95%CI, 1.18~7.48); the hands, 2.84-fold more(OR,2.84:95%CI, 1.35~5.98); the neck, 2.82-fold more(OR, 2.82;95%CI, 1.35~5.91); the back, 2.41-fold more(OR,2.41;95%CI, 1.02~5.68). The findings of the study that demonstrate the importance of good working posture are expected to make a contribution to the improvement of work environments, the development of efficient preventive programs and the preparation of sustained educational plans, and it's necessary in the future to make a research study by including psychosocial factors.

This study examines the influence of pre-service early childhood teacher's empathy and interpersonal competence on teacher efficacy. The subjects of this study include 358 pre-service early childhood teachers. The instruments used in this study were the emotional empathy scale, interpersonal competence questionnaire (ICQ) and the teacher efficacy scale. Collected data was analyzed using the SPSS program. In order to determine the general background of the pre-service teachers, the frequency and percentages were used. For examination of empathetic ability, interpersonal competence and teacher efficacy of pre-service early childhood teachers, a descriptive statistics analysis was conducted. In addition, in order to assess the relationship among empathetic ability, interpersonal competence and teacher efficacy of pre-service early childhood teachers, Pearson's correlation analysis was conducted. Lastly, for the examination of the effects and relative explanation of empathetic ability, interpersonal competence and teacher efficacy of pre-service early childhood teachers, multiple regression analysis was conducted. The results of this study were as follows: first, pre-service early childhood teachers were shown to have higher empathetic ability, interpersonal relationships and teacher efficacy rates than average. Second, there was a positive correlation among empathetic ability, interpersonal competence and teacher efficacy of pre-service early childhood teachers. Third, teacher efficacy of pre-service early childhood teachers was influenced by their empathetic ability and interpersonal competence. The results of this study suggest that teacher efficacy improvement programs for pre-service early childhood teachers should consider their empathetic ability. Also, study results emphasize the necessity of empathetic ability and interpersonal relationship improvement program for pre-service early childhood teachers.
