정인철(In-Chul Jung),락교(Rag-Gyo Jeong),최규형(Kyu-Hyoung Choi) 한국철도학회 2011 한국철도학회 학술발표대회논문집 Vol.2011 No.10
The optimization of the overhead contact lines according to the increased train speed is to design the low-sag-wire so that the pantograph can follow the vertical fluctuation of the catenary. Main factors for the overhead contact lines design include the span dropper interval movable bracket vertical fluctuation of the catenary tension and wave propagation speed. In this paper a model is proposed to improve the electric railway speed and the speed improvement analysis technology is examined to ensure the stable and reliable electric railway. In addition the effect between pantograph and catenary according to the speed improvement is quantitatively analyzed by using simulation.

Objective : The purpose of this research is to examine the effect of Sa-am acupuncture treatment(Sim-seungkyuk) for major symptoms of Hwa-byung.Method : In this randomized, single blind, placebo-controlled study, we compared active acupuncture with sham acupuncture in the treatment for major symptoms of Hwa-byung. likert scale(5 score) for major symptom of Hwa-byung was measured as the 1st evaluative instrument, and STAXI-K, STAI-K, BDI-K and HRV were also measured as the 2nd evaluative instrument at the before treatment and after treatment.Results : 26 volunteers participated in this study by dividing two groups, each 13 persons in trial group and control group at random. In comparison of likert scale for major symptoms, after treatment the total score of likert scale for major symptoms decreased significantly in both group than before treatment. And after treatment, the total score of trial group decreased less than those of control group in comparison between two groups. especially after 2 weeks from all treatment, there was significant difference between two groups. Conclusion : We considered that Shim-seungkyuk of Sa-am acupuncture treatment will be not recommended to treatment of Hwa-byung because this study could not prove effect of Shim-seungkyuk treatment for Hwa-byung in spite of preliminary study. This study will be used to provide a fundamental data for development of clinical research as preliminary study of Hwa-byung.

The 4th Bridge of Do-Kok which will be made in the third section part of work, called Chung-Ang Railroad Line(Deok-So~Won-ju) is planed that the roadbed newly established is higher than the existing roadbed. So people in Pal-Dang Li demand downward settlement of the roadbed newly established because of a prospect of The Han-River. Because of the claim, there were two conferences to analyze the field condition, terms of works and economical efficiency regarding design modification(downward settlement of design elevation(70cm), the minimum span length(40m) and height from the bottom of the slab to ground(5m). Through such conferences, it is possible to apply The Precom Beam to The 4th Bridge of Do-Kok in our construction field after investigating structural safety.

Objective: The purpose of this study was to develop a standard tool of pattern identification, which will be applied to clinical research, for benign prostatic hyperplasia. Method: The items and structure of the instrument were based on a review of the published literature in China and Korea. The advisory committee on this study included 11 kidney-endocrine professors of the Korean Medical Colleges Division and 4 Korean medicine doctors who had a doctor's degree in the Kidney-Endocrine Division. The advisory committee was questioned regarding pattern identification importance, symptom weight, treatment importance, changes in the symptoms, rare changes in the symptoms, and frequency of prescriptions regarding benign prostatic hyperplasia. Results: The Korean instrument of pattern identification was completed; it was composed of four questions for benign prostatic hyperplasia. Conclusion: We sincerely look forward to improving the instrument through the continuous clinical studies.

Objectives: This case report intended to examine how herbal medicine treatment for breathing-related sleep disorders applied with polysomnography affected the structure of sleep. Methods: From January to November 2019, we retrospectively reviewed the progress records and polysomnography reports of patients who visited Korean medical hospitals in Daejeon and Cheonan. Results: In case 1, the patient complained of daytime sleepiness and snoring and was diagnosed with obstructive sleep apnea disorder and treated with Ukgan-san-gami. There were significant changes in the polysomnographic parameters, such as sleep efficiency, waking after sleep onset, sleep latency, the total arousal index, and the apnea-hypopnea index after herbal treatment. In case 2, the patient complained of frequent waking after sleep onset, daytime sleepiness, and snoring, and was diagnosed with obstructive sleep apnea disorder and treated with Yeoldahanso-tang-gami. There were significant changes in the polysomnographic parameters, such as the total arousal index and the apnea-hypopnea index after herbal treatment. In case 3, the patient complained of daytime sleepiness and was diagnosed with obstructive sleep apnea disorder and treated with Bangpungtongsung-san. There was no significant change in the polysomnographic parameters after herbal treatment. Conclusions: It is meaningful to note that objectively identifying the outcome of treatment for breathing- related sleep disorders is necessary in the clinical practice of Korean medicine.

Objectives: This study was to investigate the associations of Parent Stress Index(PSI), Way of Coping Checklist(WCC), and Diagnostic System of Oriental Medicine(DSOM) in mothers of elementary school children. Methods: In the study, K-PSI-SF, WCC, and DSOM were carried out on 202 mothers of ○○elementary school children during June, 2010. Cross tabulation analysis was used to verify the association of PSI, WCC and DSOM. Results: 1. The most common pathogenic factor was Dampness(濕) in total subjects. 2. The score of problem-focused coping methods showed significant difference in PSI grades. 3. The zp and sc10 of Qi deficiency(氣虛), Blood deficiency(血虛), Qi-Stagnation(氣滯), Insufficiency of Yang(陽虛), Heat(熱), Dampness(濕), Dryness(燥), Liver(肝), Heart(心), and Kidney(腎) showed significant difference in PSI grades. 4. The score of total PSI and PSI subscale had negative correlations with problem-focused coping methods. 5. The score of total PSI had positive correlations with Qi-Stagnation(氣滯), Dampness(濕), Dryness(燥), Heart(心), and Kidney(腎) in total subjects. Conclusions: This study provides insights on associations of parenting stress coping methods and diagnostic system in Oriental Medicine. Furthermore, the study shows positive correlations among Qi-Stagnation(氣滯), Dampness(濕), Dryness(燥), Heart(心), Kidney(腎) and PSI, and negative correlations between PSI and Problem-focused coping methods, all with statistical significance.

The purpose of this was aimed to verify the effects of assigned goal setting on sport performance and physical self-efficacy. For this study 60 members of male high-school students are allocated into three groups. Namely, the group was assigned with upper level goal(n=20), lower level goal(n=20), and control(n=20) respectively. The soccer program was put into two times a week during eight weeks. The pre test was performed by using Soccer wall accuracy test and Physical Self-Efficacy before the soccer program. The post test was carried eight weeks after the soccer program was finished. Two-way ANOVA and Duncan`s Multiple Range test used in order to deal with the materials. In addition to these paired t-test also was used. The level of significance of all hypothesis tests wasα=.05 and the write got result as follow. 1) The performing records of soccer wal accuracy test in the group with upper level advanced significantly more than those who lower level and control groups. 2) The level of anterior and posterior perceived physical self-presentation confidence in the group with upper goal, the group with lower goal, and control group were shown significant difference. 3) The level of anterior and posterior perceived physical ability in the group with upper goal, the group with lower goal, and control group were shown significant difference. 4) The level of anterior and posterior physical self-efficacy in the group with upper goal, the group with lower goal, and control group were shown significant difference. 5) There was no effect of interaction between goal level and neither reached goal or not.
