Purpose : Accurate diagnosis of acute pyelonephritis(APN) using clinical and laboratory parameters is often difficult in children. Clinical and experimental studies have demonstrated that renal scarring can be prevented or diminished by early diagnosis and aggressive treatment of acute pyelonephritis. dimercaptosuccinic acid(DMSA) renal scan has been reported to be useful in children for confirmation of the diagnosis of acute pyelonephritis. An analysis was undertaken to correlate the clinical and laboratory manifestations of APN With the results of the DMSA renal scan in different age groups. Methods : We determined the sensitivity of DMSA renal scan in febrile urinary tract infections(UTI) in two groups according to age : group I in less than 2 years; group II in older than 2 years. During the period March 2001 through September 2002, 67 children presented with febrile UTIs. All patients had DMSA renal scan done in the acute period, 55 had voiding cystourethrography(VCUG) and 66 had renal ultrasonogram(RUS) done. Results : There were no significant difference between the two groups in DMSA renal scan (P>0.05). But, in group I sensitivity of DMSA renal scan was 47%; in group II sensitivity of DMSA renal scan was 70%. The grade of reflux correlated with a positive DMSA renal scan. Vesicoureteral reflux did not correlate with age. RUS did not correlate with a positive DMSA renal scan in any age group. Abnormality of RUS did not correlate with age. Conclusion : At present, we believe that DMSA renal scan is the prevailing method in differention of the APN. In addition, it is not invasive and less costly. Even though there is no statistical difference in the sensitivity of DMSA renal scan between young and older children, we can observe that in the younger group, the sensitivity of DMSA renal scan seemed to be lower(47%).

As a part of the short-period variability survey (SPVS) at Bohyunsan Optical Astronomy Observatory, we obtained time-series BV CCD images in the region of Cyg OB3 association centered on the open cluster NGC 6871. The observations were performed for 18 nights from September 5, 2008 to September 1, 2009. We found 15 short-period variable stars in the region. They are ${\delta}$ Scuti type stars belonging to the local spiral arm, Orion spur. Among them, only two stars were previously known, and the rest are newly discovered ones. In this paper, we have performed a multiple-frequency analysis to determine frequencies of the 15 ${\delta}$ Scuti type stars, using the discrete Fourier transform and linear least-square fitting methods. One of the newly discovered variable stars is a double-mode ${\delta}$ Scuti type star with the fundamental and the first overtone modes, and two are high amplitude ${\delta}$ Scuti stars.

To investigate the effects of self-management programs for chronic low back pain (LBP), 63 subjects were assigned to three groups; self-exercise group (SEG), hot pack and low-frequency electrical stimulation group (HEG), and thermo-massage group (TMG). Parameters were the pain numeric rating scale (PNRS), Oswestry Disability Index (ODI), Roland Morris Disability Questionnaire (RMDQ) and Relapse frequency (RF). PNRS, ODI and RMDQ of SEG and TMG sustained effectiveness, however, PNRS, which improved after treatment in HEG, worsened in 6 month. Between the groups, all parameters were better in SEG and TMG compare to HEG. Exercise and thermo-massage can be considered as useful self-management performed at home to prevent the relapse of chronic LBP.

This study intended to examine the health status and quality of life among the elderly patients who stayed in geriatric hospitals for a long period of time. The study involved 222 elderly who were older than 65-year-old, an oral examination was conducted in 10 geriatric hospitals located in the metropolitan area and Chungcheong-do. Cross-tabulation, one-way ANOVA, t-test, and Stepwise multiple regression were performed for analysis. The average number of teeth among the subjects was 11.22 and that of dental caries was 1.17. Also, the average number of teeth mobility was 0.93 and halitosis was detected among 81.9%. Only 29.70% reported absence or a kind of systemic disease and 70.31% of the subjects was shown to have more than two kinds of complex disease. In addition, 87.8% of the subjects had depression and among them, 55.40% showed serious depression. The average score on quality of life was 2.62 points and as for the related factors, the number of remaining teeth and dental caries were counted along with care grade, hospitalization period, and age. According to such results, the oral health status among the elderly patients staying long in geriatric hospitals were not good in general; also they showed high level of systemic disease and depression and low quality of life.

The purpose of this study was to investigate the outcomes and the influential factors that predict outcomes of Personal Assistance Services (PAS). A phone survey was conducted with 201 people with severe disabilities who used PAS services through 10 Centers for Independent Living. Participants reported an increase in subjective health perceptions associated with use of PAS. Participants also reported increased psychological self-reliance as a consequence of using PAS, and high satisfaction with PAS in general. Additionally, the participants reported increased active participation in their communities, increased employment, and high self-confidence in getting or maintaining jobs as outcomes of PAS. Among influential factors predicting the outcomes of PAS, high monthly income and more mean hours of for PAS were positive predictors of psychological self-reliance. Younger age, lower income, and longer duration of service were positively associated with community participation. Longer duration of disability and service use were positive predictors of employment status. Less severe disability and high monthly income were associated with higher self-confidence related to getting or maintaining a job. The results highlight the importance of ensuring the availability of PAS to all Koreans with disabilities who are interested in these services.

Farmers' perception on actual raising conditions and breeding improvement for Hanwoo were surveyed and analyzed in order to utilize such data as basic resources for further development of courses of Hanwoo improvement and instructions on raising techniques. The survey was held based on Hanwoo farmers in Gyeongbuk region and the results for the analysis were as follow. Candidate cattle for breeding was selected in consideration of 'appearance, body shape, and pedigree-registration' (39.0%) and 'artificial insemination' (38.6%) was the most frequently used breeding method for the breeding cattle. 'Body length' was revealed to be the most considered factor while purchasing fattening calves and the castration for the fattening calves were mostly performed when '6~7 months after the birth'. The farmers also responded that they 'try to comply with over 80% of items specified in program for production of high quality beef' in order to produce high quality beef. However, the farmers believed that '12 months after the birth' was the most economic market month. Although the results differed by each items surveyed, majority of those results showed statistically significant differences with significance level of 0.05 upon the surveyees' general characteristics and demographic factors including level of education, age, occupation, and family man power. Most surveyees responded 'around 30% of shipping heads' (22.1%) for the prevalence of beef graded better than 1++ grade when shipping, however, no significant differences in between general characteristics of surveyees were observed.

Purpose: The current study assessed the factors affecting outcomes of primary repair procedures in tears of multiple rotator cuff tendons. Materials and Methods: Among the cases of rotator cuff tears involving two or more tendons receiving operations between 1997 and 2003, The clinical results of 19 cases with more than 2 years follow-up were evaluated by the UCLA score. We evaluated the correlation of trauma, active motion, acromiohumeral distance, tear size, and surface area with the UCLA score using Pearson's linear correlation coefficient (PLCC). Results: UCLA scores increased significantly in all cases, from 9 to 26.1 on average. However, the results were good in 53%, and poor in 47% according to Ellman's criteria. Trauma, active elevation, acromiohumeral distance, and tear size did not correlate with the UCLA score, but the tear surface area was inversely correlated with the score (PLCC=-0.696). Cases with degeneration of the infraspinatus muscle above Goutallier grade III on MRI showed worse results than cases with less degeneration. Conclusion: The clinical results of primary repair of rotator cuff tears involving multiple tendons were satisfactory in 53% of patients. Large tear surface area and severe degeneration of the infraspinatus were poor prognostic factors.

In this study, in an attempt to elucidate the relevance and the association between AUDIT level and health related indices such as obesity-related indices (BMI, waist circumference, body fat percentage), serum liver-enzyme levels (AST, ALT, GGT, total bilirubin) and serum lipid levels (TC, TG, HDL-C, LDL-C), data about including results of health checkup examination and questionnaire from 558 male examinees of 30-79 years old, who received a comprehensive health examination in the health promotion center of a university hospital during the period of January 1 to December 31, 2012, was analysed. As a results, the distribution of AUDIT rating of subjects was Zone I 58.2%, Zone II 25.3%, Zone III 7.0%, and Zone IV 9.5%. And AUDIT levels have significant relevance with age, smoking, body fat, GGT and TG. Especially, for the waist circumference, GGT and TG, the odds ratio indicating abnormality significantly increased in the higher AUDIT groups (Zone II~Zone IV) than a low-grade group (Zone I). This suggests that drinking problem with a high AUDIT level has a significant relevance with an abnormal increase of indices for obesity, serum liver-enzyme levels, serum lipid levels.

The purpose of this study was to evaluate the effect of virtual reality distraction on pain and anxiety in children during local anesthesia. Local anesthesia was administered to 3 groups: a control group without distraction, a group watching TV, and a group using a virtual reality device. The pulse rate and oxygen saturation rate were measured before and at the time of local anesthesia to assess the patients' pain and anxiety, and the Wong-Baker Faces Pain Rating Scale was completed after local anesthesia. The group using the virtual reality device had a significantly lower heart rate change and lower Wong-Baker Faces Pain Rating Scale score than those in the control group and the group watching TV (p < 0.05). The greatest difference in heart rate change and Wong-Baker Faces Pain Rating Scale score, between the control and virtual reality distraction groups, was seen in 5 - 7-year-olds and a Frankl's behavior rating scale grade of 3. The virtual reality device alleviated pain and reduced anxiety in children during local anesthesia.
