  • Background: This study was undertaken to observe the functional changes of the hind limb and histopathological changes in the sciatic nerve after an injection of alcohol or phenol, which are commonly used neurolytic agents, highlighting the time of recovery. Methods: Forty-eight Sprague-Dawley rats weighing 200-300 g were used for the experiment. Histopathological changes under the electron microscope, were observed in the distal part of the sciatic nerve, into which 0.1 ml of alcohol or phenol was injected. This was severed in 3 rats of each group at 10 minutes, 1 hour, 24 hours, 3 days, 1, 2, 4 and 6 weeks later. The functional changes in the hind limbs were observed for 6 weeks by noting their walking pattern. Results: Following the injection of alcohol or phenol into the right sciatic nerve, the right hind limb showed a severe pronounced motor weakness and obvious gait changes. About 2 weeks later, gradual improvement of gait changes began, and after 6 weeks, the motor weakness and gait changes were no longer perceptible in both groups. The findings of any histopathological change were similar in both alcohol or phenol groups. At 10 minutes after injection, destructive lesions were confined to the unmyelinated fibers and the myelin sheath of small the myelinated fibers. On the 3rd day and at 1 week, pathologic changes in axonal fibers and Schwann cells were in being phagocytized in spite of myelin restitution. From 2 to 4 weeks, axonal regeneration and remyelination appeared at the same time a myelin disintegration and axonolysis. At 6 weeks, neural regeneration was similar to that of the contralateral control group. Conclusions: These results suggest that functional and histopathological changes, after injection of neurolytics into the peripheral nerves, are quite similar in both alcohol and phenol groups. The progression of functional and histopathological changes become more obvious according to the time interval following the injection. Consequently, side effects that develop following the use of alcohol or phenol may begin to improve around the time that nerve regeneration occurs, i.e., two to four weeks later.

  • Police agency is indicated that the number of children's traffic accident is tending downwards, however about one child is dead every day due to traffic accident. Major parts of the accidents happen during walking; among the rest, jaywalking is the biggest reason. Many accidents take plate on the road to school or near the home so government legislate children safeguard zone at 1995. According to the legislation, drivers have to reduce speed and there are safety facilities for children at children safeguard zone. This study finds the problems of children safeguard zone and suggest more effective and quantitative method for children safeguard zone. Firstly this study grasps the characters of children's pattern movement and children's traffic accident at children safeguard zone and then divides specific danger factors of children's traffic accident at children safeguard zone. Secondly, each factor is given danger level depending on danger degree and suggests effective method for assignment standard of children safeguard zone using all of these things.

  • Prosthetic replacement is one of the most common methods of reconstruction after resection of malignant tumor around the knee. Gait analysis provides a relative objective data about the gait function of patients with prosthesis. The purpose of this study was to compare the gait pattern of the patients who underwent limb salvage surgery with prosthesis for distal femur and that of patients with prosthesis for proximal tibia. This study included ten patients (4 males, 6 females, mean age 22.7 years, range 14-36) who underwent a wide resection and Kotz hinged modular reconstruction prosthesis replacement and six normal adult(Control). The site of bone tumor was the distal femur (Group 1) in six patients and proximal tibia (Group 2) in 4 patients. The follow-up period ranged from 15 to 82 months (mean : 33 months). The evaluation consisted of clinical assessment, radiographic assessment, gait analysis using VICON 370 Motion Analysis System. The gait analysis included the linear parameters such as, walking velocity, cadence, step length, stride length, stance time, swing time, single support and double support time and the three-dimensional kinematics (joint rotation angle, velocity of joint rotation) of ankle, knee, hip and pelvis in sagittal, coronal and transverse plane. For the kinetic evaluation, the moment of force (unit: Nm/kg) and power (unit: Watt/kg) of ankle, knee and hip joint in sagittal, coronal and transverse plane. In the linear parameters, cadence, velocity, step time and single support were decreased in both group 1 and group 2 compared with control. Double support decreased in group 2 compared with control significantly(p<.05). In contrast to our hypothesis, there was no significant difference between group 1 and group 2. In Kinematics, we observed significant difference (p<.05) of decreased knee flexion in loading response (G2

  • Background: We hypothesized that if a fluoroscopic image of the lumbar sympathetic ganglion block (LSGB) showed the spread patterns of contrast at both the L2/3 and L4/5 disc areas, then this would demonstrate a more profound blockade effect because the spread patterns are close to sympathetic ganglia. In addition, we compared the effects of LSGB and transforaminal epidural steroid injection (TFESI) for the patients suffering with spinal stenosis. Methods: Eighty patients were divided into two groups (Group S: the patients treated with TFESI, Group L: the patients treated with LSGB). The patients of group L were classified into three groups (groups A, B and, C) according to their contrast spread pattern. The preblock and postblock temperature difference between the ipsilateral and contralateral great toe ($DT^{pre}$, $DT^{post}$, $^{\circ}C$), and the DTnet were calculated as follows. $DT^{net}$ = $DT^{post}$ - $DT^{pre}$. Results: Both group showed a significant reduction of the visual analogue score (VAS) and the Oswestry disability index (ODI) score. Only the patients of group L showed a significant increase of their walking distance (WD). Group A showed the most significant changes in the $DT^{post}$ ($6.1{\pm}1.2^{\circ}C$, P = 0.021), and the DTnet ($6.0{\pm}1.0^{\circ}C$, p = 0.023), as compared to group C. Conclusions: LSGB showed a similar effect on the VAS, and ODI, and a significant effect, on WD, compared with TFESI. Group A showed a significant sympatholytic effect, as compared to group C.

  • This research was designed to find out what is a distictive feature of the design elements of Korean women's costume and its influence by analizing the trend of Korean women's constume during the period of 1890 and 1995. The research was analized by a total of 854 random samples of clothing styles collected from materials in the museums and from articles of three leading newspapers and one of the best women's magazines in Korea. The changing trend of Korean women's costume was found out to be as follows: 1. In around 1910s, the trend of Korean women's costume has been changed into two-tier structure of both Korean and Western styles, and the typical and traditional Korean women's street wears such as 'Chang-ot' and 'Tsdechima' have been gradually diminished. 2. From 1920s, length of the Korean skirt, which was unnecessarily long and inconvenient, has been getting shorter for the convenience of walking. In addition, Korean women's underwear has become simplified, and sports wear could be seen for the first time in Korea. 3. During 1960s, the Western clothing styles have been increased rather than Korean styles as the street wear of the Korean women. 4. In 1970s, blue jeans, mini-skirts and casual wears have become a trend or fashion for women in Korea. 5. In 1980s, a fashion of unisex mode has arrived in this country, and from the year of 1987, wearing of panties among the Korean women has been increased rather than skirts wearing for the street wear. 6. During 1990s, various forma of complex styles came into being in such styles as so-called 'orange class style,' 'protruding navel T-shirts' and 'runner wear speedy.' From mid-1990s, Korean women have turned out to prefer the cute and light costumes by placing emphasis on the image of intellectual, professional and functional wears. The changing special feature of the Korean women's clothing designs could be distinctively observed during 1960s as the modernization policies in Korea have been processed during the period. The clothing trend before 1960 was to change and to solve problems of inconvenient and impractical wears, but the trend after 1960 was seen as a change to confirm a trend of the world fashion. From mid-1990s, however, preference of Korean women's self-conceited conception socially and an unquestionable changing pattern of Korean women's life.

  • A multidisciplinary weight control program was conducted for obese women. The major components of the program included low calorie diet therapy, exercise, behavior modification and nutritional education and counseling. Sixteen healthy volunteers in excess of body fat, above 30%, were enrolled in the group support program. But 5 person were dropped out in the 2nd week of treatment. During the 1st week of group orientation, individual cause of obesity was assessed through a computer program including survey of dietary intake, activity, eating habits and life styles. During the 5 weeks of treatment, 4.8kg of average weight loss was accomplished using a following program ; low calorie diet(1200kcal/day with all essential nutrients), low impact aerobic exercise(50~60% of $VO_{2max}$, 1 hour/day in a group, 3~5 days/week), behavior modification of individual life styles and eating habits causing obesity and nutritional education concerning nutrition, role of exercise such as brisk walking, importance of slow eating in regular meal pattern and internal motivation for weight reduction, health risk of obesity and rapid weight loss, weight recycling and yo-yo syndrome, etc. Nutritional conseling was conducted 3 times per week with checking self-records of foods, activity, emotional state and tiredness. Before and immediately after 5 weeks of treatment, blood pressure, fasting blood glucose, cholesterol and triglyceride were measured and comparied with paired t-test. After 5 weeks of treatment, body weight, body mass index, body fat and circumferences of waist, upper arm and hip were significantly decreased. Also LDL-cholesterol was significantly decreased after obesity treatment.

  • Purpose: This retrospective chart review study was conducted to examine the frequency of delirium and to identify the risk factors of delirium in elderly surgical patients. Methods: The subjects of this study were 394 patients aged 65 years or older who underwent surgery. The diagnosis of delirium was based on the nursing assessment records with scores from the day of surgery to the 4th day after surgery. The collected data were analyzed by binary logistic regression analysis. Results: The incidence of delirium was 4.3%, and delirium occurred most frequently on the first day of surgery and lasted for 2.16 days on average. Of delirium patients, 76.5% underwent gastrointestinal surgery, and the most common delirium pattern was disorientation. In terms of the characteristics of the subjects, the occurrence of delirium was statistically different by age (𝝌2=10.79, p=.005), systemic-specific disease (𝝌2=9.63, p=.047), use of delirium-inducing drug(benzodiazepine) before surgery (𝝌2=15.90, p<.001), walking ability before surgery (𝝌2=7.65, p=.006), history of delirium (𝝌2=35.92, p<.001), and emergency surgery (𝝌2=16.40, p<.001). As risk factors of delirium, gastrointestinal surgery was found to increase the risk of delirium by 12.57 times (95% CI=2.45~64.46, p=.002), and the use of benzodiazepines before surgery was shown to increase delirium by 10.07 times (95% CI=2.21~45.87, p=.003). Conclusion: It is necessary for nurses to actively evaluate delirium using screening tools for early detection and prevention of delirium in elderly surgical patients with delirium risk factors.

  • Objectives : This paper aims to examine the meaning of Shengmaisan in relation to original qi based on the discussion of Zhangyuansu, Lidongyuan and other doctors. Methods : Discussion of Shengmaisan made by Zhang, Li and others were examined. Afterwards, the medicinal properties of renshen, maimendong, and wuweizi as written in the Bencaogangmu, Donguibogam, Benjingshuzheng and texts of Zhang and Li were studied in relation to original qi. Related concepts such as '肺中伏火'·'補肺中元氣不足'·'補天眞元氣'·'夏食寒' were analyzed as well. Results & Conclusions : 1. Various pathology related to deficiency in original qi could act as internal pathogen for Shengmaisan application with which external factors such as summerheat and dampness heat meet results in most damage in the Lung metal. Therefore the upper body Lung is emphasized as pathogen. 2. The pathology of Shengmaisan application is depletion of humor, which should be refined, due to summer or dampness heat in a state of original qi deficiency which damages the Lungs, disabling its function of managing clear and pure qi. 3. The disease pattern for Shengmaisan in relation to original qi, according to other doctors, includes symptoms related to the Lungs such as dryness in the mouth due to excessive perspiration, blankness, loss of consciousness, shortness of breath, coughing, fast breathing, along with general bodily symptoms such as heavy sensation of the body, lethargy, difficulty walking, limping. These general bodily symptoms are due to either qi deficiency of the Lung, or humor deficiency due to failure of qi convergence in the lower body, or symptoms caused by Jing deficiency in severe cases. Symptoms related to problems in the lower body could manifest as dysfunction in urination and defecation, weakness in the limbs caused by original qi deficiency. 4. The Lungs circulate the clear and pure qi, converging qi and creating humor to assist the Triple Burner's Qi-Humor metabolism, enabling smooth communication of original qi throughout the body. With the original qi well tonified, the shen mechanism which is rooted in original qi allows for autonomous and consistent qi circulation within the body. Therefore, both Zhang and Li emphasized the importance of original qi. The property of Shengmaisan is explained as 'supplement qi/create liquid, convergence of yin/stop perspiration'. Zhang and Li explained its property as managing the circulation of original qi, to tonify Lungs' original qi and origin of water-humor.
