For the improvement of denture fitness of changed residual ridge, denture liner can be used. Denture liner should be very stable physically in various environments of the mouth as well as be bonded strongly with denture resin. In this study, the specimens bonded with four kinds of soft denture liner and three kinds of hard denture liner were used to test the physical properties of the liners. All experimental groups were stored in 37+/-1degrees C distilled water for 24hours, followed by thermocycling between 15degrees C and 45degrees C with 15 second dwell time. 1000, 2000, 3000 cycles of thermocycling were excuted and physical properties were measured by Instron Universal Testing Machine. The obtained results were as follows: 1. In tensile bond test of soft liners, it was shown that both of Molloplast-B(R) specimens before and after thermocycling had the highest tensile strength, and in case of hard liners, Dura-liner II(R)speimen had the highest tensile strength before and after thermocycling. Depending on thermocycling, Soft-Relining(R), Denture-Relining(R),Molloplast-B(R), Coe-soft(R) and Kooliner(R) specimen showed significant difference(p<0.05). 2. In strain test of soft liners, it was shown that Molloplast-B(R) specimen before thermocycling and the Coe-soft(R) after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) speimen before and after thermocycling had the highest result. Depending on thermocycling. Denture-Relinig(R). Molloplast-B(R) and Dura-Lner II(R) specimen showed significant difference(p<0.05). 3. In Maximum distance test of soft liners, the Molloplast-B(R) specimen before thermocycling and the Coe-soft(R) after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) specimen before and after thermocycling showed highest results. Depending on thermocycling, Denture-Relining(R), Molloplast-B(R) specimens showed significant difference(p<0.05). 4.In elasticity test of soft liners , the Molloplast-B(R) specimen before and after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) specimen before thermocycling and the Tokuso-Rebase (R) after thermocycling showed highest results. Depending on thermocycling, Soft-Relining(R) , Molloplast-B(R) specimens showed significant difference(p<0.05).

2.The Effects of Curl-up Exercise with XCO on Trunk Muscle Activation in Healthy Adults
Journal of Korean Physical Therapy 2020;32(4):210-216
Purpose:
This study examined the effects of curl-up using XCO® on trunk muscle activation in healthy adults.
Methods:
This study design was a single-blind randomized controlled trial. Twelve participants were enrolled in this study. The subjects were instructed to perform curl-up exercise in STCU (straight curl-up), LTCU (left twist curl-up), RTCU (right twist curl-up), TWCU (twist curl-up), and PPCU (power push curl-up). Electromyography was used to assess the percent maximal voluntary isometric contraction (%MVIC) of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinae (ES) muscles. The data were analyzed using two-way ANOVA with a repeated measure. The statistical significance level was set to α=0.05
Results:
The IO showed significant differences in the main effect of the group and the interactions between the group and exercise (p<0.05). In particular, the IO represented the interactions between group and exercise in the RTCU and PPCU (p<0.05). The RA, EO, and ES did not show significant interactions between the group and exercise (p>0.05). The RA, IO, and EO showed significant differences in the main effect of the group (p<0.05). The EO showed a significant difference in the main effect of exercise (p<0.05).
Conclusion
These findings suggest that XCO® can be used to increase the muscle activation of the internal oblique, which is the lumbar stabilizing muscle, when XCO® is combined in the curl-up exercise with rotation. In the future, research on the intensity, frequency, and duration of XCO® exercise will be needed according to the individual characteristics and preferences.

4.Coping Strategies for Stress in Patients with Social Phobia-Comparison of Generalized and Nongeneralized Social Phobia.
Journal of Korean Neuropsychiatric Association 2003;42(4):507-513
OBJECTIVES: The purposes of this study were to understand the difference of coping strategies for stress and to compare the degree of social avoidance, subjective distress and fear of negative evaluation between patients with generalized and nongeneralized social phobia. METHODS: Forty-six outpatients meeting the criteria of DSM-IV social phobia at the Department of Psychiatry Kangbuk Samsung Hospital were included. They were classified as generalized type (n=30) and nongeneralized type (n=16) according to the number of difficult situations. Social Phobia Scale (SPS), Social Avoidance and Distress Scale (SADS) and Brief-Fear of Negative Evaluation (BFNE) scales were administered to both groups. To evaluate the coping strategies for stress, we used 'Multidimensional Coping Scale'. RESULTS: 1) The group of generalized social phobia showed significantly lower scores on emotional expression and religious seeking and showed higher scores on passive withdrawal in multidimensional coping scales than the group of nongeneralized social phobia. 2) The group of generalized social phobia reported greater subjective fear of situation in which the patients were exposed to scrutiny by others than did the group of nongeneralized social phobia. The group of generalized social phobia tended to report severer anxiety and to avoid social situation that may be embarrassing far greater than did in group of nongeneralized social phobia. 3) In both groups, social avoidance and distress were positively correlated with passive withdrawal and emotional support and negatively correlated with active coping. Fear for negative evaluation was positively correlated with fatalism and negatively correlated with positive interpretation. CONCLUSION: Efficient and active intervention to change unproductive coping strategy such as passive withdrawal is essential in the treatment of social phobia patients. Also this study suggests that interventions designed to modify behaviors and cognitions in emotional support seeking and fatalism could improve symptoms.

Journal of Korean Physical Therapy 2017;29(4):201-206
PURPOSE: The aim of this study was to identify the effects of Pilates mat exercise may improve trunk muscle thickness and balance in healthy adults. METHODS: Eighteen healthy adults participated in this study. They were randomly assigned to one of two groups: Pilates mat exercise group (n=9) and the control group (n=9). Subjects in Pilates mat exercise group performed the exercises three days per week for 6 weeks, which consisted of warm up, main workout, and cool down. Trunk muscle thickness of the rectus abdominis (RA), internal oblique (IO), external oblique (EO), transverse abdominis (TrA), multifidus (MF), and erector spine (ES) were measured using an ultrasonography. Balance ability was evaluated using Romberg test and limits of stability (LOS). Measurements were performed before training, 3 weeks after training, and 6 weeks after training. RESULTS: There was a significant difference of RA, EO, IO, MF, and ES according to the main effect of time (p<0.05). There was a significant difference of EO, MF, ES, Romberg, and LOS according to interaction effect between the time and group (p<0.05). There was a significant difference only for LOS according to the main effect of the group (p<0.05). CONCLUSION: Pilates mat exercise did increase trunk muscle thickness and balance. However, the effect with respect to trunk thickness was limited. Pilates mat exercise appears to be more effective in improving muscles related to trunk extension and balance.

Malignant mixed m llerian tumor (MMMT) of the ovary is very rare neoplasm consisting of both a sarcomatous and carcinomatous component and represent is fewer than 1% of all ovarian malignancies. Characteristically, ovarian MMMTs follow an aggressive clinical course, and long-term survival is unusual. Almost all MMMTs are found in postmenopausal women, often with low parity and usually in an advanced stage. Stage has been recognized as the single most important prognostic factors. However, a major improvement in prognosis for this rare malignancy has not yet been achieved. The authors have experienced one case of primary malignant mixed m llerian tumor of the ovary and report our experience with a brief review of literature.

Eccrine poroma is a benign neoplasm that originates from an eccrine sweat duct. Although it is most commonly found on the soles of the feet, it has also been unusually observed on many other areas of the skin, such as the nose, neck, chest, and scalp. We report two cases of eccrine poroma occurring on the scalp, which is an unusual location.

Adrenocortical carcinoma is a rare tumor in children. This tumor is more likely to be hormonally active in children than in adults and tends to cause a variety of symptoms. These tumors are usually diagnosed at the advanced stages and have a dismal prognosis. Here we report a case of a functioning adrenocortical carcinoma in a child with a review of the relevant literature.

Continuous ambulatory peritoneal dialysis (CAPD) is an effective renal replacement therapy for the end stage renal disease. The hydrothorax secondary to leakage of dialysate via pleuroperitoneal communication is a rare complication of CAPD. A variety of symptoms are complained. The regular chest X-ray and pleural fluid examination are needed to find out this complication with vague symptoms. Although our understanding of its mechanisms is incomplete, it is apparent that the key to successful therapy is obliteration of a transdiaphragmatic route of dialysate leakage (pleuroperitoneal communication). Several treatments of CAPD-induced hydrothorax have included pleurodesis with tetracycline, talc, fibrin, or autologous blood and surgical treatment. We have recently managed with a patient CAPD-induced massive hydrothorax with decreased amount of effluent dialysate volumes using talc pleurodesis. This patient was successfully returned to CAPD.
