We prepared an anti-adhesion membrane made of sodium hyaluronate/sodium carboxymethylcellulose (HA/CMC) and evaluated its effectiveness for adhesion prevention in a rat model. The anti-adhesion membrane was prepared by lyophilizing HA/CMC solution and cross-linking properly with 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDAC). In a cecum/abdominal wall abrasion model of Sprague-Dawley rat, cecal serosa and abdominal wall were abraded in $1\times2\;(cm^2)$ with a bone burr after peritoneal midline incision and sutured at 3 points around the injured surface. The denuded cecum was covered with HA/CMC membrane (experimental group), or nothing (control group) and apposed to the abdominal wall. Most of the control group represented 3 or more of adhesion grade at POD 7, 14, 21, and 28, whereas $60\~70\%$ of the experimental group was 2 or less of adhesion grade at 14, 21, and 28. It was similar in the adhesion strength. In a general manner, the adhesion grade and strength showed gradual increasing until POD 14, almost same or a little increasing POD 21, but decreasing POD 28. Also the control group was much higher in adhesion grade, strength, and area than the experimental group. It is expected that the anti-adhesion membrane will have a good clinical result in postoperative adhesion prevention.

Probabilistic reasoning and combinational reasoning are essential to build a logical thinking and a process of thinking dealing with everyday life as well as scientific knowledge. This research aims at finding the optimal period to teach reasoning to the students who haven't developed probabilistic reasoning and combinational reasoning. The treatment program was performed for 20 students from each grade who couldn't develop two parts of reasoning. The treatment program using baduk stones and cards was performed repeatedly, focusing on the specific activities. After four weeks of treatment program, the test to check the development of probabilistic reasoning and combinational reasoning was performed again and the changes of reasoning development were identified. After giving treatment program for reasoning development, 15.0%, 25.0% and 40.0% of improvement in the 4th, the 5th, the 6th graders respectively were shown. With regard to the combinational reasoning, the results showed the improvement of 20.0% in the 4th grades, 25.0% in the 5th graders and 63.2% in the 6th graders. As a result of research in the above, students, who were not formed probabilistic reasoning and combinational reasoning, could be known to be enhanced through learning, but to fail to be formed the qualitative change like the cognitive development. It is expected that this research can contribute to the improvement of students' cognitive level and there would be more active researches in different fields to improve the cognitive level of the 6th graders who are in their optimal periods to learn two parts of reasoning.

The purpose of this study was to investigate the recognition of middle school students on 'Thinking Science' activities and the influence on the understanding of the gas particles behavior concepts. For this study 125 students of four classes first grade in middle school were divided into two groups, the experimental and the control group. The SRT II test was carried out to identify the cognitive level of the students. The logical factors, needed to understand of the gas particles behavior concepts, were extracted. And the 9 'Thinking Science' activities designed to develop these factors were chosen and then implemented to the students of the experimental group. After the lesson for the gas particles behaviors, the achievement test of understanding of the gas particles behavior concepts and the survey of the students' recognition on 'Thinking Science' activities were administered. According to the results of the achievement test, there was not significant difference between the two groups on the whole. But only mature concrete operational students in the experimental group got high scores than those in the control group in analyzing the effect size. According to the results of the ANCOVA analysis, there was significant difference between the two girls' group. When students in the experimental group had a positive perceptions about 'Thinking Science' activities, they got higher achievement scores. This implied that there was a correlation between perception about 'Thinking Science' activities and their achievement in the gas particles behavior concepts. Especially, students with positive perception in mature concrete operational period got higher scores in science achievement. After the 'Thinking Science' activities, there was a high perceptions about improving in scientific thinking.

A 2-year-old, 2 kg Maltese dog was evaluated for progressive tetraparesis and neck pain. The dog had been treated with steroids for the preceding 2 weeks after unknown trauma but was deteriorating progressively and had become tetraparetic. The dog was presented with a non-ambulatory tetraparesis. Radiographic and computed tomographic examinations revealed a transverse C2 fracture with subluxation of the atlantoaxial joint and C2-C3. In addition, hydrocephalus was observed on magnetic resonance imaging. Stabilization of C1-C3 using screws, wires, and polymethyl methacrylate (PMMA) was performed. Application of ventral screws, wires, and PMMA resulted in improvement of the clinical signs after 4 weeks, and the dog could walk as before the tetraparesis 6 weeks after the operation. This stabilization method is an effective surgical treatment for management of cervical instability.

Objectives : The aim of this study was to evaluate the therapeutic effect of acupuncture and herbal medicine in patients who had hvpoactivity of the gastric vagus nerve and pyloric valve disturbance simultaneously with function dyspepsia by bowel sounds analysis. Methods : Bowel sounds of 10 patients (male 1, female 9) were recorded and their % of bowel sound (%BS) and ratio of dominant frequency (DF) were analyzed before and after treatment. Hypoactivity of the gastric vagus nerve was considered if % BS was <6%. and pyloric valve disturbance was accepted if DF ratio (e.g.. postprandial DF/fasting DF) was <1. Electroacupuncture at Zusanli (ST36, 3Hz, 30 minutes) and manual acupuncture at other meridian points were applied daily for 2 weeks. Herbal medicine, Pyengwi-san. was administered to all patients (100cc, 3 times/day). Results : DF ratio significantly increased from $0.93\pm0.06$ to $1.06\pm0.04$ after treatment for 2 weeks (p=0.005). 9 of 10 patients were improved to DF ratio>1. %BS also increased from $2.97\pm1.17%$ to $4.49\pm4.27%$. not significantly. 3 patients showed a remarkable elevation, and their %BS reached >6% of normal value. Conclusions : Combined effect of electroacupuncture at Zusanli (ST36), manual acupuncture. and Pyengwi-san was shown effective in the improvement of pyloric valve disturbance more than hypoactivity of gastric vagus nerve on patients with functional dyspepsia.

The purpose of this study was to compare the effectiveness of rehabilitation therapy with natural recovery in patients who had dysphagia due to stroke. Swallowing functions were examined on a total of 98 patients with stroke-caused dysphagia based on a videofluoroscopic swallowing study (VFSS) for 8 weeks. The each group was evaluated with DOSS, DSS and FOSS to assess swallowing ability in the first week and re-evaluated in the $8^{th}$ week during the session for investigating the recovery status. The author compared the above initial data and follow-up data using a Mann-Whitney U test, Kruskal-Wallis test and Wilcoxon's Signed Rank test, ANCOVA to confirm statistically controlling for the effects of other continuous variables, performed by IBM SPSS Statistics 20.0 for windows. There was statistically significant recovery in the experimental group except measure of DOSS (p>0.05). In the control group, it showed improvement in all the scales(p<0.05). After terminating each session, the comparison of the two group of patients showed statistical significant differences in DSS and FOSS(p<0.05). These results suggest that possibility of natural neurologic recovery has positive effects on early stage of dysphagia caused by stroke.

This study was conducted to investigate the effect of aromatherapy on the autonomic nervous system by the inhalation. The subjects of the study were 64 people aged 20 and under 59 years old, 32 in the experimental group and 32 in the control group. Blending oil with Six aroma(Lavender, Bergamot, Mandarin, Lemon, Cedarwood, Roman Chamomile) was applied to the experimental group, and Jojoba oil was applied to the control group for 30min. Before and after the experiment, HRV(TP, VLF, LF, HF, LF/HF) of the experimental group and the control group were compared and analyzed using pulse wave mesuring instrument(uBioClip v70). There was a significant difference between the experimental group and the control group in 3 out of 5 items analyzed TP(p<.05), LF(p<.05), HF(p<.01). In other words, aromatherapy increases the total activity of the autonomic nervous system by enhancing the TP, increases the activity of the sympathetic and parasympathetic nerves, promotes the activity of the heart, Facilitate the activity of the heart. Therefore, if aromatherapy is used steadily in everyday life, it will enable healthy life by positively affecting the autonomic nervous system response.
