The purpose of this study was to confirm the effect of core stability exercise, dong-bang therapy, and combined treatment on reducing pain, pelvic correction and stress hormone concentration in patients suffering from sciatic neuralgia due to pelvic displacement. Middle aged(40~50age) suffering from sciatic neuralgia over 6 months were operated with core stability exercise, dong-bang therapy, and combined treatment 3 times a week for 12 weeks. VAS and X-ray was performed to collect pain scales and pelvic displacement data and cortisol and epinephrine concentration in blood were tested. 1. pain scale rate was reduced in all groups. especially, dong-bang therapy group and combined treatment group showed more directive pain reduce. 2. pelvic displacement improvement was not significant in core stability exercise group, and it was significant in dong-bang therapy group and combined treatment group. no significant difference was shown between dong-bang therapy group and combined treatment group. however, combined treatment group showed higher correction effect. 3. concentration of stress hormone was significantly increased in all groups after the first operation. after 12 weeks concentration level was reduced to same level before treatment. Dong-bang therapy and combined treatment improve pelvic displacement, and are effective treatments on reducing sciatic neuralgia due to pelvic displacement. combined treatment of dong-bang treatment and core stability exercise is considered an effective program of correction for pelvic displacement and maintenance.

The physicochemical and microbiological traits of the Hanwoo beef jerky were analyzed during the aerobically packaged storage at 25oC. The water activities of beef jerky with 0.5% and 1.0% SH were lower than those of the control at 0 d (p

Effect of Inhomogeneous Nucleation of Hydride at α/β Phase Boundary on Microstructure Evolution of Zr–2.5 wt%Nb Pressure Tube

Sung‑Soo Kim,Sangyeob Lim,Dong‑Hyun Ahn,Gyeong‑Geun Lee,Kunok Chang 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.4

We analyzed the microstructural characteristics such as number density and length and width of hydrides in Zr–2.5 wt%Nbpressure tube. The hydrogen was charged cathodically and the hydride-contained sample was evaluated using the advancedanalysis methodologies. We performed a diff erential scanning calorimetry analysis to more quantitatively understand thethermodynamics of the hydride formation/growth process. We characterized the micrograph of hydride-contained Zr samplesto estimate the microstructural characteristics of the matrix and hydrides. We investigated eff ects of hydrogen concentrationand microstructure of matrix on determining microstructural measures of the hydrides. Particularly, we found that β phasein the matrix becomes isolated during the heat treatment same or above 475 °C and this change increases the inhomogeneousnucleation sites signifi cantly. We claim that the microstructure change of this matrix phase greatly increases the numberdensity of hydride.

慶尙北道내 肺吸蟲 浸潤地 溪谷에서의 가재의 最近 棲息狀과 가재에서의 폐흡충 피낭유충의 最近 寄生狀을 究明코저 1981年 10月부터 1982年 9月까지 6個處(達城郡 嘉昌面 蛇洞, 玉盆洞, 上院洞과 榮豊郡 豊基邑 錦溪, 英陽郡 英陽面 化川 및 靑松郡 府東面 上宣溪谷)를 調査對象溪谷으로 選定하여 調査한 後 1974年 朴 및 崔의 調査 成績과 比較하였다. 6個處의 肺吸蟲 浸潤地에서의 가재의 棲息密度는 1974年의 그 密度에 比하여 顯著히 低下되었으며 가재에서의 폐흡충 피낭유충의 寄生率과 그 寄生程度도 1974年의 成績에 比하여 낮았다. 가재의 體部位別 폐흡충 피낭유충의 寄生狀에 있어서는 1974年에는 가재의 全體部位에서 本피낭유충을 찾아 볼 수 있었는데 比하여 이번 調査에서는 가재의 頭胸部, 아가미 및 肝에서만 찾아볼 수 있었으며 가재 한마리當 폐흡충 피낭유충數도 全浸潤地에서 1974年에 比하여 1982年에는 甚히 적었다. 폐흡충 피낭유충이 寄生하는 가재의 數와 이들 가재에서의 本피낭유충의 數가 1982年에는 너무 적으므로 가재의 크기와 本피낭유충數 및 1974年의 調査成績과의 相關을 求할 수 없었다. 이번 調査 結果 1974年에서 1982年까지의 지난 8年間 폐흡충 浸潤地에서 가재의 棲息密度와 폐흡충 피낭유충이 寄生하는 가재의 數가 急激히 減少되었음을 알았다. In an attempt to determine the recent patterns of population density of the crayfish, Cambaroides similis, and infestation of the crayfish with the metacercaria of Paragonimus westermani in Kyungpook Province, Korea, the crayfish collected in the six endemic areas, Kum-ge, Wha-cheon, Sang-seon, Ju-dong, Ok-bun dong, and Sang-weon dong streams were examined from April, 1981 to September, 1982. The results obtained in 1982 were compared with the data derived from the crayfish collected at the same streams by Park and Choi(1974). The population density of crayfish in the six endemic areas of P. westermani in the present study decreased markedly compared with those in 1974. The infestation rate for the metacercaria of P. westermani in the crayfish examined and the intensity of infestation in the positive crayfish also decreased compared with those reported by Park and Choi(1974). In the 1974 survey, the metacercaria was found in all parts of the crayfish whereas it was found only in the cephalothorax, the gills, and the liver in the present suevey. In the average number of metacercariae perpositive crayfish (M.P.P.C), a pronounced reduction was encountered in all endemic areas between 1974 and 1982. The number of infested crayfish and the metacercaria of P. westermani in infested crayfish in 1982 was so small that it was impossible to analyze the relationship between the number of metacercaria and the length of crayfish and to compare the data between 1974 and 1982. It was found in the present study that the population density of crayfish in the endemic areas and the infestation of the crayfish with the metacercaria of P. westermani has decreased drastically over the eight-year period from 1974 to 1982.

Hye-Sung Lee,Hyun-Su Baek,Dong-Suk Song,Hee-Chul Kim,Hyo-Geun Kim,Bok-Joo Kim,Myung-Soo Kim,Sang-Hoon Shin,Sung-Hee Jung,Chul-Hoon Kim 대한구강악안면외과학회 2013 대한구강악안면외과학회지 Vol.39 No.1

Objectives: This study sought to evaluate the effect of simultaneous application of arthrocentesis and occlusal splint. Materials and Methods: A retrospective study of 43 patients (3 males, 40 females) whose symptoms had improved was conducted at the Department of Oral and Maxillofacial Surgery, Dong-A University Hospital between 2008 and 2010. Subjects were divided into three groups: Group A (17 patients with arthrocentesis and occlusal splints simultaneously applied), Group B (13 patients whose symptoms did not improve with occlusal splints, undergoing arthrocentesis after occlusal splint use for 8 weeks), and Group C (13 patients that only used occlusal splints). We compared these groups in maximum comfortable opening (MCO) and the visual analogue scale of pain and noise. Follow-up was performed at 1 week, 1 month, 3 months, and 6 months. Results: The improvement of symptoms was noted in all three groups, but Group A had a quicker improvement than the other groups, in terms of pain reduction and MCO increases. Conclusion: The simultaneous application of arthrocentesis and occlusal splints can reduce patient discomfort more quickly.

강동수(Dong Soo Kang),최상용(Sang Yong Choi),이광찬(Kwang Chan Lee),김진승(Chin Seung Kim) 대한소화기학회 1993 대한소화기학회지 Vol.25 No.5

N/A The 19 months clinical experiences about 634 cases of laparoscpic surgery were reviewed at Sung-Ae General Hospital from July 1991 to Jan. 1993 The results were as follows; Among 168 cases of laparoscopic cholecystectomy and 5 cases of laparoscopic CBD exploration, we obtained better results with advantages of laparoscopic surgery including few complications, less morbidity and early return to work. In series of 361 cases of laparoscopic appendectomy, we obtained superior results especially in the cases of 1) uncertainty of clinically suspected appendicitis, 2) right lower quadrant pelvic pain without other pathology and 3) patients who wanted early return to work. In series of spontaneous pneumothorax with bullae and recurrent pneumothorax, the thoracoscopic bullectomy was much superior than open bullectomy. The laparoscopic Taylor procedures and laparoscopic bandlysis will be better choice in the management of intractable pain in duodenal ulcer and postoperative adhesion. The diagnostic laparoscopy will be much useful in the blunt and penetrating abdominal trauma.

Prediction of Retained Austenite Fraction in Quenching-and-Partitioning (Q&P) Steels Using the Gibbs Energy Balance Approach

Seong Hoon Kim,Ji Hoon Kim,Jae Hoon Lee,Dong‑Woo Suh,Jae Sang Lee 대한금속·재료학회 2022 METALS AND MATERIALS International Vol.28 No.9

Prediction of retained austenite fraction is quite important in designing advanced high strength steels since retained austeniteis the source of transformation-induced plasticity. The present study investigates the phase constitution of a medium-carbonQ&P steel by comparing various approaches to the transformation stasis of bainitic ferrite and applying them to the partitioningprocess. Among them, the modified GEB approach gave the best agreement with the experimental observation, includingthe effects of heat-treatment condition and chemical composition on phase constitution. This indicates phase transformationduring partitioning can be effectively described by the physics of Gibbs energy balance approach.
