Background: Video-assisted thoracoscopic sympathicotomy has been determined to be the best way to treat palmar hyperhidrosis. However, satisfaction with the surgical outcomes decreases with the onset of compensatory hyperhidrosis (CH) over time. The ideal level of sympathicotomy is controversial. Therefore, we compared the long-term results of R3 and R4 sympathicotomy. Methods: We retrospectively reviewed 186 patients who underwent video-assisted thoracoscopic sympathicotomy between September 2001 and September 2015. We analyzed the long-term results with respect to hand sweating and CH, and the overall satisfaction in 186 patients. Results: With respect to hand sweating, significantly more patients complained of overly dry hands in the R3 group (25% versus 3.7%, p<0.001) and of mildly wet hands in the R4 group (2.9% versus 13.4%, p=0.007). There was a significantly increased occurrence rate of CH in the R3 group (97.1% versus 65.9%, p< 0.001). The most frequent site of CH was the trunk area. The overall satisfaction was higher in the R4 group, but without significance (75% versus 85.4%, p=0.082). Significantly more patients reported being very satisfied in the R4 group (5.8% versus 22.0%, p=0.001). Conclusion: T he R4 group had a higher rate of satisfaction than the R3 group with respect to hand sweating. CH and hand dryness were significantly less common in the R4 group than in the R3 group. The lower occurrence of hand dryness and CH resulted in a higher satisfaction rate in the R4 group.

High serum cholesterol level is a major risk factor for coronary heart disease(CHD). Nutrition therapy of hypocholesterolemic diets with increased physical activity is the essential step in the treatment of the hypercholesterolemic patients. The purpose of this study was to evaluate the short-term effect of intensive dietary therapy combined with regular exercise in lowering serum cholesterol level. Seventy three hypercholesterolemic outpatients(mean: 268.0$\pm$24.7mg/dL), aged 34 to 73(mean: 56$\pm$9.8yrs), who visited cardiology OPD of Yonsei Cardiovascular Center from April through October, 1998 were studied. Anthropometric measurements, usual nutrient intake survey using semiquantitative food frequency questionnaire, and daily nutrient intake analysis were performed. The nutrition counseling for the hypocholesterolemic diet and exercise therapy was performed individually. After a 4 week intensive dietary therapy, comparisons of body weight, nutrient intakes, and blood lipid concentrations were evaluated for the hypocholesterolemic effect of intensive diet therapy. After 4 weeks of intensive diet therapy, significant reductions in percent ideal body weight(p<0.01), saturated fat intake(p<0.01), and cholesterol intake(p<0.01) were observed. There were significant reductions in serum total cholesterol and LDL-cholesterol levels after 4 weeks of therapy by 8.1%(p<0.01) and 9.7%(p<0.01), respectively. Our results showed that intensive dietary therapy was effective in reductions of serum total and LDL-cholesterol levels. The goal for this dietary modification should not be temporary but rather be permanent in eating behavior accompanied by appropriately increased physical activity.

The aim of this study was to identify the optimal and superior type of natural calcium for replacing phosphate in cooked ground pork products. To achieve this, 0.5% eggshell calcium (ESC), oyster shell calcium (OSC), marine algae calcium (MAC), or milk calcium (MC) was added to ground pork meat products. The effect of this substitution was studied by comparing the substituted products with products containing 0.3% phosphate blend (control). ESC was considered an ideal phosphate replacer for minimizing the cooking loss, which likely resulted from the increase in the pH of the product. Among the other natural calcium types, OSC treatment did not cause a significant increase in pH, but it lowered the cooking loss. CIE $L^*$ values were higher (p<0.05) in products treated with OSC or MC than the control, and lowest (p<0.05) in the products with ESC. However, products with ESC had higher (p<0.05) CIE $a^*$ and CIE $b^*$ values than the control and products treated with other powders. Compared to the control, products treated with ESC and OSC had similar substitution effects on the textural properties of the products. Therefore, the results of this study suggested that the combined use of ESC and OSC could be a potentially effective method for replacing synthetic phosphate in ground pork products.

This study investigated the influence of weight perception on weight management strategies including diet and exercise in Korean female adolescents. Junior (J) and senior (S) high school girls were divided in two groups; those who had $\leq$100% (BI) and > 100% (AI) of ideal weight (J-BI, n=376, 14.8 yr, 46.1 kg; J-AI, 11=128, 15.0 yr, 57.4 kg; S-BI, n=325, 17.4 yr, 50.1 kg; and S-AI, n=133, 17.5 yr, 58.2 kg, mean values). Questionnaires to assess weight perception, desire to lose weight, body image, eating behavior, weight control strategies and physical activity (PPA) were administered J-AI(9.4 kg) and S-AI(9.8 kg) desired to lose weight more than J-BI(2.5 kg) and S-BI(3.6 kg), respectively (p < 0.001). 85% of J-AI and 93% of S-AI perceived their weight being above average and 23% of J-BI and 34% of S-BI responded similarly (p < 0.001). Body dissatisfaction index (BDI) and eating attitude (EAT26) scores were lower in J-BI(9.7, 12.0) vs. J-AI(16.4, 14.7) and S-BI(12.4, 12.4) vs. S-AI(19.5, 15.4) (p < 0.001). However, PPA was not different for J-BI vs. J-AI, and S-BI vs. S-AL Only 17, 18, 9, and 15% of J.BI, J.AI, S-BI, and S-AI, respectively, exercised regularly. PPA and BDI were only slightly correlated in J-BI(r=0.194, p < 0.005) and S-BI(r=0.220, p < 0.005). Even that the majority of Korean female adolescents perceived they were heavy and desired to lose weight, appropriate exercise and physical activities were not practiced.

Purpose : Clinicians commonly encounter cases in which it is difficult to determine whether adjacent radiopacities are normal or pathologic. The ideal radiopacity of composite resin is equal to or higher than that of the same thickness of aluminum. We aimed to investigate the possible effects of different curing times on the post-24-hour radiopacity of composite resins on digital radiographs. Materials and Methods : One mm thick samples of Filtek P60 and Clearfil resin composites were prepared and cured with three regimens of continuous 400 mW/$cm^2$ irradiance for 10, 20 and 30 seconds. Along with a 12-step aluminum step wedge, digital radiographs were captured and the radiopacities were transformed to the equivalent aluminum thicknesses. Data were compared by a general linear model and repeated-measures of ANOVA. Results : Overall, the calculated equivalent aluminum thicknesses of composite resins were increased significantly by doubling and tripling the curing times (F(2,8)=8.94, p=0.002). Notably, Bonferroni post-hoc tests confirmed that the radiopacity of the cured Filtek P60 was significantly higher at 30 seconds compared with 10 seconds (p=0.04). Although the higher radiopacity was observed by increasing the time, other comparisons showed no statistical significance (p>0.05). Conclusion : These results supported the hypothesis that the radiopacity of resin composites might be related to the duration of light curing. In addition to the current standards for radiopacity of digital images, defining a standard protocol for curing of dental materials should be considered, and it is suggested that they should be added to the current requirements for dental material.

Background: Peptides have diverse and important physiological roles in plants and are ideal markers for species identification. It is unclear whether there are specific peptides in Panax quinquefolius L. (PQ). The aims of this study were to identify Quinetides, a series of diverse posttranslational modified native peptides of the ribonuclease-like storage protein (ginseng major protein), from PQ to explore novel peptide markers and develop a new method to distinguish PQ from Panax ginseng. Methods: We used different fragmentation modes in the LTQ Orbitrap analysis to identify the enriched Quinetide targets of PQ, and we discovered Quinetide markers of PQ and P. ginseng using ultrahigh-performance liquid chromatography-quadrupole time-of-flight mass spectrometry analysis. These "peptide markers" were validated by simultaneously monitoring Rf and F11 as standard ginsenosides. Results: We discovered 100 Quinetides of PQ with various post-translational modifications (PTMs), including a series of glycopeptides, all of which originated from the protein ginseng major protein. We effectively distinguished PQ from P. ginseng using new "peptide markers." Four unique peptides (Quinetides TP6 and TP7 as markers of PQ and Quinetides TP8 and TP9 as markers of P. ginseng) and their associated glycosylation products were discovered in PQ and P. ginseng. Conclusion: We provide specific information on PQ peptides and propose the clinical application of peptide markers to distinguish PQ from P. ginseng.

The purpose of this study was to examine the impact of the DISC behavioral patterns of health care workers on their job satisfaction, organization Commitment and job stress in a bid to suggest an ideal behavioral pattern of Nurses and Dental hygienist. The subjects were 184 health care workers who worked in general hospitals and clinics in Busan and Ulsan for a year or more. The collected data were analyzed using ANOVA and linear regression. As a result of analyzing the relationship of their DISC behavioral patterns to job stress, organizational satisfaction and organizational commitment, there were significant differences in job stress according to their DISC behavioral patterns(p=0.015). In regard to relationship between their DISC behavioral patterns and the subfactors of job stress, there were significant gaps in role conflicts(p=.007), conflicts with subordinates(p=0.001) and conflicts over underpayment(p=0.015) according to their DISC behavioral patterns. As a result of investigating the influential factors of job stress, factors produced significant results(p<.001). The findings of the study illustrated that out of the DISC behavioral patterns, type I was most prevailing among the health care workers, which indicated that the weight of this type was highest among the behavioral styles. There were no significant gaps in job satisfaction and organizational commitment according to their DISC behavioral patterns.
