The aim of this study was to investigate the variation in shape, size and area of the pharynx and adenoids, and to analyze the relationship between pharyngeal cavity and upper facial cranium which effected on morphology of those parts in Korean. Age changes and sex differences in those areas were comprised in this study. Materials included 272 lateral cephalograms, which were divided into 4 groups by age; (1) 7-year-old group consisted of 29 males and 30 females, (2) 12-year-old group consisted of 30 males and 30 females, (3) 17-year-old group consisted of 30 males and 40 females, (4) 20-year-old group consisted of 37 males and 46 females. In subjects each variable was measured and evaluated statistically introducing 17 reference points and 17 reference lines respectively. Conclusions from this study were as follows. 1. Linear measurements of the bony nasopharynx revealed that the depth and height were larger in male than those in female in 17 and 20-year-old groups. 2. Linear measurements of the upper facial cranium were larger in male than those in female in all age groups. 3. Angular measurements of the bony nasopharynx and upper facial cranium did not show, on an average, sex differences in each age group. 4. As regards area of the bony nasopharynx, it increased gradually with age in both sexes. And the area was greater in male than that in female in 17 and 20-year old groups. 5. There were sex differences in area of the adenoids of which the area was larger in male than that in female in 17 and 20-year-old groups. And the area reached a peak at 17-year-old group in male and at 12 year-old group in female. 6. Area of the pharyngeal cavity increased gradually with age in both sexes, but no sex differences were noted in each age group. 7. Rate of area of the adenoids to that of the pharyngeal cavity decreased continually with age, and no sex differences were noted in all age groups. 8. In amounts and its differences of the growth, there were sex differences in the posterior upper facial height, and were not in area of the bony nasopharynx, pharyngeal cavity and adenoids in each age group.

This study was tried to investigate the effectiveness of assertive training on the state anxiety and assertive behavior which nursing students had experienced during clinical practice training from April 29, to June 5, 2000. Subjects for this study were thirty-six nursing students of practicing in a general hospital. Eighteen nursing students were assigned for the experimental group and trained by assertive training program during 4 weeks and eighteen nursing students were assigned for the control group. The assertive training program was composed of cognitive, behavioral and emotional assertive training. Post- test assessment was administrated to all subjects on a week later after the last session. The data were analyzed with SPSS PC programs. The results of this study were summarized as follows: 1) There were no significant differences between the experimental group and the control group on post- intervention comparisons of the state anxiety score (p=0.230), but in the experimental group, the anxiety score more decreased after the assertive training than that in the control group with significant differences(p=0.019). 2) There were no significant differences between the experimental group and the control group on post- intervention comparisons of assertive behavior (p=0.530). However, after the assertive training, the experimental group became more assertive than the control group with no significant differences(p=0.721). 3) The hypothesis that the more the assertive behavior, the less the state anxiety experienced by nursing students of clinical practice training was supported(r=-0.397, p=0.017). On the basis of this study results, the assertive training is effective for the reduction of the state anxiety experienced by nursing students of clinical practice training.

Background: The purposed of this study is to examine the static and dynamic plantar foot pressure in chronic low back pain patients and normal adults. Methods: The subjects were divided into a group of 30 patients with chronic low back pain and a control group of 30 healthy persons. While static posture and dynamic posture at comfortable walking speeds, the low back pain group and the control group measured their plantar foot pressure and the trajectory of their center of pressure (COP) using the Matscan(R) system. Independent t-tests were measured to compare differences in plantar foot pressure characteristics between the left side and right side of the low back pain group and the control group. Results: In the comparison of differences in plantar foot pressure characteristics between the left side and right side of the low back pain group and the control group, the anteroposterior (AP) displacement of COP showed significant differences (p<.05). Although the low back pain group and the control group did not show any significant differences in leg length, weight distribution, mediolateral (ML) displacement of COP, static contract area, dynamic contract areas (p>.05), increases in the contract area values were shown in the hind foot in general. Conclusion: In this study, it was shown that patients with chronic low back pain were walking with short AP displacement of the COP as a compensatory action to avoid pain.

Background: Tapered grafts, which have a smaller diameter on the arterial side, have been increasingly used for arteriovenous fistula (AVF) formation. We compared the outcomes of 4-6-mm tapered and 6-mm straight forearm loop arteriovenous grafts. Methods: A total of 103 patients receiving forearm loop arteriovenous grafts between March 2005 and March 2015 were retrospectively analyzed and separated into 2 groups (group A, 4- to 6-mm tapered grafts, n=78; group B, 6-mm straight grafts, n=25). In each group, complications and patency rates after surgery were assessed. Results: Clinical characteristics and laboratory results, except for cerebrovascular disease history (group A, 7.7%; group B, 28.0%; p=0.014), were similar between the groups. No significant differences were found for individual complications. Kaplan-Meier survival analysis revealed no significant differences in 1-year, 3-year, and 5-year patency rates between groups (61.8%, 44.9%, and 38.5% vs. 62.7%, 41.1%, and 35.3%, respectively). Conclusion: We found no significant differences in complication and patency rates between the tapered and straight graft groups. If there are no differences in complication and patency between the two graft types, tapered grafts may be a valuable option for AVF formation in light of their other advantages.

In view of the hypothesis that the effects of Parkinson disease on voice production can be detected before pharmacological intervention, the voice differences of patients with Idiopathic Parkinson's disease and a healthy aging group were diagnostically analyzed with the long term object of establishing, for clinical purposes, early disease-progression biomarkers. Fifteen patients with Idopathic Parkinson's disease (prior to pharmacological intervention) and a healthy control group of 15 were selected and every voice was recorded three times using praat (ver. 5022) with a headset mic. Relevant parameters - acoustic measure of /a/ phonation, F0 related parameters, MPT related parameters, articulatory ratio, VOT - were then analyzed by MANOVA. Significant differences were found in the F0 related (low F0, high F0, F0 range) and MPT related parameters. There were also significant differences in acoustic measurements (intensity, shimmer, HNR, jitter), AMR (/$t{\Lambda}$/,/$k{\Lambda}$/) and VOT (/ta/), The findings indicated that the voice production of patients with Idiopathic Parkinson's disease have normal pitch but bad quality. In particular, with slow articulatory ratios and VOT values, the tongue tip functioning of patients was lower than for the healthy group.

This study investigated the effect of physical training and oxidative stress on the anti oxidative activity and on plasma lipid profile. Forty eight rats were given either a physical training or no training for 4 weeks and were then subdivided into 3 groups: before-exercise (BE); during-exercise (DE); after-exercise (AE). The antioxidative activity was evaluated with the activities of catalase in plasma and superoxide dismutase (SOD), the ratio of reduced glutathione/ oxidized glutathione (GSH/GSSG) and the level of malondialdehyde (MDA) in liver. The plasma concentrations of triglyceride (TG), total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C)) were also compared. Compared to those of non-training group. catalase activities of training group were lower before exercise but higher during and after exercise. SOD activities were higher regardless of exercise. GSH/GSSG ratio was higher before exercise but was not significantly different during exercise and even lower after exercise. There were no differences between non-training group and training group in MDA levels regardless of exercise. Compared to those of non-training group, atherosclerotic index of training group was lower after exercise and there were no significant differences before and during exercise. There were no differences between non-training group and training group in HDL-C regardless of exercise. These results suggest that moderate physical training can activate antioxidant defenses and decrease the atherosclerotic index and this beneficial effect is evident under exercise-induced oxidative stress.

This study aims to compare and analyze the differences of emotional responses between two types of e-magazines published - one with cinemagraph images and another with general still images. To conduct this study, a total of nine pages were prepared with different contents according to each theme and samples of e-magazine with a total of nineteen sections of images were exposed to a total of thirty persons of subjects. Fifteen persons were assigned to the experimental group viewing the cinemagraph images, and other fifteen persons were assigned to the control group viewing the general still images. As a result of the experiment, the emotional responses of the experimental group and the control group were significantly different. Twenty-eight items of positive emotional responses out of forty-two items of the emotional responses were more found in the experimental group, and fourteen items of negative emotional responses affected the control group more. In the experimental group where the differences in the mean value and significant differences were found, negative emotional responses were not examined but fourteen positive emotional response items such as Loveliness, Merriness, Freshness, Activeness, Attractiveness, Powerfulness, Heartwarming, Joyfulness, Interesting, Confidence, Excitement, Cheerfulness, Humorousness, and Amazement were found; in the control group, positive emotional responses were not found but three items of negative emotional responses such as Ambiguousness, Stuffiness, and Boredom were found.
