The purpose of this study was to find purchase appraisal standard and post-purchase satisfaction for natural dyeing products. The data used for this study were collected from the women in their from 20's to 50's who are living in the regions of Busan, Ulsan, and Gyeongnam in Korea. The questionnaire of 537 copies was used for a statistical analysis. To analyze data, 2-test, t-test, Cronbach's a test, factor analysis, ANOVA, Duncan test, regression analysis, etc. were carried out. A used statistical package was SPSS 14.0. The analysis results were as follows. The purchase appraisal standards for natural dyeing products were identified as practicality and reliability, suitability of use, symbolic property of status, design property, and convenience of buying. As the analysis result for purchase appraisal standard according to the demographic characteristics, the purchase appraisal standard according to most demographic characteristics showed significant difference. The factors of post-purchase satisfaction for natural dyeing products were verified as product modification and durability, design and price, hygienic property and product quality. As the analysis results of post-purchase satisfaction for natural dyeing products according to demographic characteristics, the post-purchase satisfaction according to demographic characteristics showed significant difference. The factors affecting post-purchase satisfaction were verified as product quality, kinds of item, color change, product lifespan, color change, etc. Consequently, because the purchase appraisal standard of natural dyeing product is very various, it is necessary to enhance post-purchase satisfaction of natural dyeing products by reflecting these factors in advance at the product development stage.

The aim of the present work was to investigate how colour changes of foal meat can vary after thawing out in relation to the slaughtering age of the horses and to the post-thawing time. Eighteen Italian Heavy Draught Horse (IHDH) foals were used for the trial. They were subdivided in three groups according to their slaughtering age (6, 11 and 18 months). Two different surfaces were investigated for each sample: a fresh cut surface (daily renewed cutting surface: DRCS), and not-renewed cutting surface (NRCS). The redness of both investigated surfaces increased with slaughtering age (p<0.01). Moreover, this parameter decreased during post-thawing time (p<0.01) only on the NRCS, probably due to the myoglobin oxidation processes. Colour is an important visual cue denoting perceived quality by consumers. So, by a chromatic perspective the thawed meat of IHDH foals slaughtered at 6 and 11 months proved to be that which best meets the market requirements.

The purpose of this study was to evaluate the effects of Kinesio taping(KT) on the maximal power and muscle activity of erector spinae. 30 male subjects were allocated in this study and randomly divided into experimental and control groups. All subjects were measured for maximal power of trunk extensors and muscle activities of iliocostalis lumborum, longissimus, and multifidus between pre and post experiment. Maximal power was calculated using a dynamometer(Power Track II, JTECH medical, USA), and muscle activities were calculated using a surface EMG(MP150 BIOPAC System Inc. CA. USA). Maximal power of trunk extensor showed no significant difference between pre and post intervention in both groups(p>0.05). Muscle activity of iliocostalis lumborum, longissimus, and multifidus showed no significant difference between pre and post intervention(p>0.05). Finally, there was no significant difference between Experimental and control group in maximal power and muscle activity of trunk extensor. These study results suggested that KT did not affect increase or decrease in maximal power and muscle activities of trunk extensor.

Boerhaave's syndrome is a very fatal condition occuring esophageal rupture during emesis and has the worst prognosis of the esophageal perforation. From May 2007 to March 2012 11 patients underwent surgical treatment for Boerhaave's syndrome at Inje University Sanggye Paik Hospital. There were 11 males whose mean age was 49.9 years ranging from 42 to 59. 2 cases of primary closure was performed and 9 cases of anastomosis using EEA (Esophago-Enteric Anastomisis) stapler. Mean operation time was 154.4 minutes and one patient who undergone primary repair died because of mediastinitis and sepsis on $35^{th}$ post-operative day. There was no leakage at other patients. Post-operative complication was one operative wound infection and one post-operative bleeding which was treated completely. Surgical treatment for Boerhaave's syndrome using EEA stapler is simple and effective technique but further studies with large number of cases should be carried out for better outcome.

Purpose: The purpose of this study was to examine the effects of microteaching for student health educators. Methods: Subjects included 43 students in the nursing department of "H" university. In order to measure the degree of self-efficacy and speech anxiety at pre-treatment and post-treatment, subjects in the experimental group underwent training in microteaching. Results: No significant difference of variance in self-efficacy and speech anxiety was observed between subjects in the experimental group and those in the control group. However, self-confidence, a sub-domain of self-efficacy, showed a significant increase from pretest to post-test. In addition, speech anxiety measured during the post-test showed improvement, when compared with that of the pretest. Conclusion: Findings of this study provide preliminary evidence that microteaching may result in improved speech behavior.

Transparent conductive ZnO/Ag/ZnO (ZAZ) multilayer films were deposited by Radio frequency (RF) magnetron sputtering and direct current (DC) magnetron sputtering. The effects of post deposition vacuum annealing temperature on the structural, electrical and optical properties of the ZAZ multilayer films were investigated. The thickness of ZAZ films is kept constant at ZnO 50 nm/Ag 5nm/ZnO 45 nm, while the vacuum annealing temperatures were varied from 200 and $400^{\circ}C$, respectively. As-deposited ZAZ films exhibit a sheet resistance of $6.1{\Omega}/{\Box}$ and optical transmittance of 72.7%. By increasing annealing temperature to $200^{\circ}C$, the resistivity decreased to as low as $5.3{\Omega}/{\Box}$ and optical transmittance also increased to as high as 82.1%. Post-deposition annealing of ZAZ multilayer films lead to considerably lower electrical resistivity and higher optical transparency, simultaneously by increased crystallization of the films.

PURPOSE. Debonding of a composite resin core of the fiber post often occurs at the interface between these two materials. The aim of this study was to evaluate the effects of different surface treatment methods on bond strength between fiber posts and composite core. MATERIALS AND METHODS. Sixty-four fiber posts were picked in two groups (Hetco and Exacto). Each group was further divided into four subgroups using different surface treatments: 1) silanization; 2) sandblasting; 3) Treatment with 24% $H_2O_2$, and 4) no treatment (control group). A cylindrical plexiglass matrix was placed around the post and filled with the core resin composite. Specimens were stored in 5000 thermal cycles between $5^{\circ}C$ and $55^{\circ}C$. Tensile bond strength (TBS) test and evaluation using stereomicroscope were performed on the specimen and the data were analyzed using two-way ANOVA, Post Hoc Scheffe tests and Fisher's Exact Test (${\alpha}$=.05). RESULTS. There was a significant difference between the effect of different surface treatments on TBS ($P$ <.001) but different brands of post ($P$=.743) and interaction between the brand of post and surface treatment ($P$=.922) had no significant effect on TBS. Both silanization and sandblasting improved the bonding strength of fiber posts to composite resin core, but there were not any significant differences between these groups and control group. CONCLUSION. There was not any significant difference between two brands of fiber posts that had been used in this study. Although silanization and sandblasting can improve the TBS, there was not any significant differences between surface treatments used.
