This study was carried out to identify the effects of an art therapy program based on reality therapy on the weight control, body image, and self-esteem of college students. The program was developed by the authors. The design was a pretest-post test control group design. The subjects were college students attending M college : 8 in experimental group A, 6 in experimental group 2, who wanted to control their body weight and 16 in the control group who didn't attend the program. those in the experimental group attended the program once (group A) or twice (group B) per week meeting a total of six times. The data were analyzed by quantity method (SPSS 10.0 program) and quality method(process analysis). The results were as follows ' 1. The average obesity index of pre-test, post-test, and a follow-up test decreased from 8.9% to 6.1%, 3.7%. And the rate of decrease broth pre-post and post-follow up were statistically significant. 2. The average obesity index of group A decreased from 9.6% to 6.3%, 4.1% and the rate of decrease between pre and post were statistically significant. But the rate of decrease between post and follow-up were statistically not significant. 3. The average obesity index of group B decreased from 7.8% to 5.8%, 3.1% and the rate of decrease between pre and post were not significant statistically. But the rate of decrease between post and follow-up were statistically significant. 4. The average scores of pre and post body image increased and were statistically significant : group A from 129.0 to 153.5, group B from 127.7 to 156.2. 5. The average scores of pre and post semantic differential method increased and were statistically significant : group A from 38.1 to 44.1, group B from 38.0 to 45.0. 6. The average scores of pre and post self-esteem increased : group A increased from 37.3 to 40,3 and were statistically significant, group B increased from 36.5 to 39.5 but was statistically insignificant. 7. The average scores of pre and post obesity rate, body image, semantic differential method and self-esteem in the control group were not statistically significant. 8. The pre and post scores of body image(p=.001), semantic differential method(p=.001) and self-esteem(p= .039) between experimental and control group were statistically significant. 9. In Duncan multiple comparison, it was not statistically significant between group A and B, but statistically significant between group A and the control group, group B and the control group in obesity index, body image, semantic differential method. There was no statistically significance among the three groups in self esteem. 10. In Duncan multiple comparison, group A gained tougher scores than group B in obesity index(-1. 2%), and self esteem(0. 3). Group B gained higher scores than group A in body image(3. 0), and semantic differential method(1. 0). So it is difficult to conclude whether group A or B is more effective. In conclusion, the art therapy program based on reality therapy was effective in weight the control program of college students: obesity was decreased, the scores of body image and semantic differential method and self-esteem were increased. The scores of group A were increased more than group B and were statistically significant, The time interval was a very important factor in this program. The recommendation is : the validity of this program has to be tested through various subjects and in various areas. And also tutus program has to be tested in other topics.

<P><B>Abstract</B></P> <P>This study is aimed at alleviating the inherent disadvantages of sulfur cathodes in lithium-sulfur (Li-S) batteries by encapsulating the sulfur particles with a dual (ionic and electronic)-conducting polymer via a simple, single-step procedure. Successful encapsulation by the polymer was confirmed by microscopic analyses. The encapsulated sulfur electrodes exhibit stable cycling performance and high sulfur utilization; in particular, the cell with 1 wt% dual conducting polymer-coated sulfur particles exhibit the best cycle performance with a discharge capacity of 1002 mAh g<SUP>−1</SUP> after 100 cycles at 0.2 C-rate. As opposed to various sulfur-carbon composites reported previously, our 1 wt% dual conducting polymer-coated sulfur composite achieves a very high loading level of 99%. This simple strategy of encapsulating sulfur particles with functional polymers could be a potential pathway toward the commercialization of Li-S batteries.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Sulfur particles in Li-S battery were coated by a dual-conducting polymer. </LI> <LI> Encapsulated electrodes show high cycle performance and sulfur utilization. </LI> <LI> Battery with 1 wt% polymer-coated sulfur electrode gives best cycle performance. </LI> <LI> This polymer coating method will aid the commercialization of Li-S batteries. </LI> </UL> </P>

<P>Inorganic pyrophosphatase (PPase) catalyzes the hydrolysis of pyrophosphate to form orthophosphate. Pyrophosphate can substitute for ATP under certain circumstances. We previously conducted a proteomic analysis to investigate tumor-specific protein expression in gastric cancer, and PPase was identified as a potential gastric tumor-specific marker; it was therefore selected for further study. Clinicopathological analysis, using proteomic analysis and immunohistochemistry, was used to validate PPase as a prognostic marker in gastric cancers. Proteomic analysis showed that PPase was overexpressed in patients with lymph node (LN) metastases and high tumor node metastasis (TNM) stages (p < 0.05). Based on immunohistochemistry, patients whose tumors overexpressed PPase had higher T stages, LN metastasis, a higher TNM stage, a higher cancer recurrence rate, and shorter survival times than patients whose tumors exhibited PPase underexpression (p < 0.05). Gain-of-function and loss-of-function approaches were employed to examine the malignant phenotypes of PPase-overexpressing or PPase-depleted cells. A decrease in PPase expression caused a significant decrease in gastric cancer cell migration and invasion in vitro, whereas forced overexpression of PPase enhanced migration but not invasion. Our findings indicate that PPase is involved in gastric tumor progression and that PPase may be a useful marker for poor prognosis of human gastric cancers.</P>

Purpose: To evaluate the clinical spectrum of posttransplantation lymphoproliferative disorder (PTLD) after solid organ transplantation (SOT) in children. Methods: We retrospectively reviewed the medical records of 18 patients with PTLD who underwent liver (LT) or kidney transplantation (KT) between January 1995 and December 2014 in Seoul National University Children's Hospital. Results: Eighteen patients (3.9% of pediatric SOTs; LT:KT, 11:7; male to female, 9:9) were diagnosed as having PTLD over the last 2 decades (4.8% for LT and 2.9% for KT). PTLD usually presented with fever or gastrointestinal symptoms in a median period of 7 months after SOT. Eight cases had malignant lesions, and all the patients except one had evidence of Epstein-Barr virus (EBV) involvement, assessed by using in situ hybridization of tumor tissue or EBV viral load quantitation of blood. Remission was achieved in all patients with reduction of immunosuppression and/or rituximab therapy or chemotherapy, although 1 patient had allograft kidney loss and another died from complications of chemotherapy. The first case of PTLD was encountered after the introduction of tacrolimus for pediatric SOT in 2003. The recent increase in PTLD incidence in KT coincided with modification of clinical practice since 2012 to increase the tacrolimus trough level. Conclusion: While the outcome was favorable in that all patients achieved complete remission, some patients still had allograft loss or mortality. To prevent PTLD and improve its outcome, monitoring for EBV infection is essential, which would lead to appropriate modification of immunosuppression and enhanced surveillance for PTLD.

<P><B>Abstract</B></P> <P>In this article, structure, dielectric, ferroelectric and piezoelectric properties of Bi rich Bi<SUB>1.05</SUB>(Zn<SUB>0.5</SUB>Ti<SUB>0.5</SUB>)O<SUB>3</SUB>-modified BiFeO<SUB>3</SUB>-BaTiO<SUB>3</SUB> (BF-BT-<I>x</I>BZT) ceramics were investigated experimentally. Crystal structure, phase purity and microstructure were examined through X-ray diffractometry and scanning electron microscopy, respectively. The crystallographic results show the formation of single-phase solid solutions for all compositions except <I>x</I> = 10 mol%. The BF-BT modification through BZT instigates variation in grain size, enhancement in Curie temperature (<I>T</I> <SUB>C</SUB>) and field induced polarization and strain response. Large field induced strain of ∼0.24% at low driving field along with a small hysteresis of ∼38% was observed for 2 mol% BZT modified BF-BT ceramics. These investigated results signpost the potentiality of BF-BT-<I>x</I>BZT ceramics in high temperature piezoelectric device applications.</P>
