The effect of kinesio taping in patients with common peroneal nerve paralysis (PNP) have not been investigated. This purpose of this study was to evaluate the effects of kinesio taping on patients with common PNP. Ten subjects who had common PNP were included in this study. Kinesio taping was applied to the ankle joint (direction of dorsiflexion and eversion). The measurements were by manual muscle test (MMT; tibialis anterior, peroneus longus), active ROM (ankle dorsiflexion, eversion), pain (visual analogue scale (VAS), pressure pain threshold (PPT)), and balance (one leg standing). Subjects were assessed at baseline and 8 weeks of intervention. In the results, all subjects showed improvements in MMT, active ROM, Pain and balance at the 8-week. These findings are considered to be effective in applying kinesio taping on ankle joint in common PNP patients.

Objectives: Ryodoraku diagnosis has been used frequently since Nakatani invented it in 1950. There are many papers about how to use Ryodoraku diagnosis in many diseases, but there are no studies about the repeatability and reproducibility of the Ryodoraku score. The aim of this study was to investigate the repeatability and reproducibility of the Ryodoraku score. Materials and Methods: There were four examiners who trained for more than a month, and the number of subjects was twenty. Each of the examiners made Ryodoraku diagnosis for ten subjects three times. We analyzed data by SPSS, used Friedman test, Wilcoxon signer rank test and Spearman correlation test. Results: 1. There was no significant difference between first, second, and third Ryodoraku score by Friedman test in examiners A, B, C, and D, so there was repeatability. 2. There was very high correlation on first, second, third Ryodoraku score by Spearman correlation test in examiners A, B, C, and 0, so there was repeatability. 3. There was high ICC among Ryodoraku score by examiners B, C, and D, so there was reproducibility. 4. After observing four examiners' Ryodoraku diagnoses, we could see the discord of measure points, the amount of hydration before examination, the amount of pressure, examination time, or positions of subjects diagnosed with Ryodoraku incorrectly. Conclusion: There is repeatability and reproducibility of Ryodoraku diagnosis. However, it is still important that one examiner carry out the diagnosis if possible. When there are two or more examiners, they should train extensively and follow manuals.

Objective: The purpose of this study is to compare the workload level at each lower limbs posture and suggest the ergonomic workstation guideline for working period by evaluating the imbalanced lower limbs postures from the physiological and psychophysical points of view. Background: Many workers like welders are working in various imbalanced lower limbs postures either due to the narrow working conditions or other environmental conditions. Method: Ten male subjects participated in this experiment. Subjects were asked to maintain 3 different lower limbs postures(standing, squatting and bending) with 3 different working conditions(balanced floor with no scaffold, imbalanced floor with 10cm height of scaffold, and imbalanced floor with 20cm height of scaffold). EMG data for the 4 muscle groups(Retus Femoris, Vastus Lateralis, Tibialis Anterior, Gastrocnemius) from each lower limbs posture were collected for 20 seconds every 2 minutes during the 8 minutes sustaining task. Subjects were also asked to report their discomfort ratings of body parts such as waist, upper legs, lower legs, and ankle. Results: The ANOVA results showed that the EMG root mean square(RMS) values and the discomfort ratings(CR-10 Rating Scale) were significantly affected by lower limbs postures and working time(p<0.05). The correlation was analyzed between the EMG data and the discomfort ratings. Also, prediction models for the discomfort rating for each posture were developed using physical condition, working time, and scaffold height. Conclusion: We strongly recommend that one should not work more than 6 minutes in a standing or squatting postures and should not work more than 4 minutes in a bending posture. Application: The results of this study could be used to design and assess working environments and methods. Furthermore, these results could be used to suggest ergonomic guidelines for the lower limbs postures such as squatting and bending in the working fields in order to prevent fatigue and pain in the lower limbs body.

Objective: This study tried to examine the muscle activity of the neck and trunk according to head posture changes during use of laptops. Design: Cross-sectional study. Methods: This study included nineteen young men and women. All subjects maintained each posture while practice typing on laptops for ten minutes with a 5-minute break between each posture. For the neutral head posture, the subjects practiced typing while pulling their chins down towards the Adam's apple and were able to look at their knees while having their external auditory meatus, acromion, and greater trochanter vertical to the ground. For the natural head posture, they practiced typing while balancing their posture between extension and flexion of the cervical vertebrae by themselves without any guidelines. While a forward head posture was created by having their heads face the front horizontal to the rope hanging from the ceiling, they practiced typing with their external auditory meatus located in the place which was 5 cm in front of the vertical plane. The subjects used general word process but practiced typing with accuracy and high speed. Muscle activities were randomly measured using surface electromyography according to each postures. Results: The research result had found that muscle activity with the natural head posture was more significantly reduced than that of the forward head posture in the sternocleidomastoid muscle, upper trapezius, cervical vertebral spinae, and thoracic vertebrae spinae muscles (p<0.05) and that the neutral head posture was more significantly reduced than that of forward head posture in the upper trapezius, cervical vertebral spinae, and thoracic vertebrae spinae muscle activity (p<0.05) with significant increases in lumbar spinae muscle activity (p<0.05). Also, muscle activity with the neutral head posture significantly increased more in the sternocleidomastoid muscle and lumbar spinae than that of the natural posture (p<0.05). Conclusions: Our study results suggest that in order to prevent musculoskeletal pain, the neutral head posture with use of laptops is effective in reducing load to the shoulders and vitalizing the postural muscles.

The purpose of this study was to determine the effects of landing height information on landing strategy during a drop landing. Ten healthy male subjects(age: $22.1{\pm}1.9year$, height: $178.4{\pm}7.8cm$, mass: $75.3{\pm}9.4kg$) participated in this study. Each participant was asked to jump with both legs off a 40 cm high box on one of the three plates with different thickness (0 cm, 13 cm, 26 cm). In the first condition, subjects were given both cognitive and visual information about the jumping heights. In the second, they were given only cognitive information without visual one, and in the third, no information about the height was provided to subjects. (Only the data collected from the 40 cm height landing were analyzed and reported in the present study.) The results showed that landing strategies during a double-leg drop landing from 40 cm height were not significantly affected by visual and cognitive information blockages. Also, there were no statistically significant differences in landing strategies between the three conditions even though the mean differences attained in this study seemed to warrant further studies investigating the relationship between landing strategies and cognitive information.

The purposes of this study was to investigate the physical compensation for gait on induced equinus in normal subjects. Ten subjects were participate in the experiment (age: $23.8{\pm}2.8yrs$, height: $177.3{\pm}4.3cm$, weight: $70.8{\pm}4.6kg$). The study method adopted 3D analysis with six cameras and ground reaction force with two force-plate. Induced equinus were classify as gait pattern on unilateral and bilateral equinus. The results were as follows; In displacement of COM, medio-lateral and anterior-posterior COM were no significant, but in vertical COM, unilateral equinus gait was higher than bilateral equinus gait. In displacement hip joint, left hip joint was more extended in FC1 and FC2 during unilateral equinus gait. In displacement knee joint, left knee joint was more extended in FC2, right knee joint was more extended in all event during unilateral equinus gait. In trunk tilt, unilateral equinus gait was more forward tilt in TO1 and TO2. ROM of each joint was no significant. In Displacement of pelvic tilt angle, X axis of unilateral equinus gait was more increase than bilateral equinus gait at FC2, TO2 and MS2. Y axis of unilateral equinus gait was more increase than bilateral equinus gait at MS1, FC2 and MS2. Z axis was no significant in both equinus gait. In GRF, right Fx and Fy were no significant in both equinus gait, Fz was more bigger vertical force in bilateral equinus gait. Left Fx was more bigger internal force in unilateral equinus gait, Fy and Fz were no significant in both equinus gait.

The purpose of this study is to evaluate the information science education provided by the undergraduate courses of the departments of library science of the Korean universities by looking at major topics included in the syllabi distributed to students in the past three years. It is important to determine the evaluation of the professional education for information specialists by the graduates of the departments of library science who have acquired a critical appreciation of their professional studies and speak from experience about the relavance of the programme to their work and careers, and by the managers of information service units where the graduates would eventually make their careers. Specifically, the study addresses the following four questions. (a) To what excent do the information science curricula contribute to advancement of theory and practice of the information profession? (b) To what extent do the information science curricula contribute to students in acquiring the knowledge and skills required of the information specialist? (c) To what extent are the employers' concerns reflected in the information science curricula? (d) What reforms are needed to bring the current information science curricula closer to the present and future needs of the information profession? To answer these questions, the study is conducted in two main parts: an in-depth subject analysis of the articles of three important journals in the field of information science published during the past ten years and of the syllabi used for information science subjects taught in the departments of library science during the past three years and an extensive survey of the graduates of departments of library science and their principal employers. The major findings are as follows. The average number of 4.1 subjects of information science is offered in departments of library science, and the most common subjects offered are introduction to information science, information storage and retrieval, and library automation. Approximately two thirds of the total output of research and development in the field of information science are taught at one or more departments of library science in Korea. Majority of the graduates of the departments of library science comment that their professional education did not offer to them systematic orientation to the specifics of the first job. The employers of the graduates believe that departments of library science should provide sufficient practicums to enable students to understand and apply the theory.

This study was carried out to examine the effects of alcohol on serum lipid levels. Subjects of this study were 50 military officers living in Honsung, Korea, 25 of whom consumed alcohol on a regular basis and 25 of whom did not. All subjects were previously informed of the purpose of the study and the methods of food intake reporting and blood testing. The age distribution range of subjects was 30-49 years. Weight, height, and body mass index(BMI) were not significantly different between the two groups. Blood pressure was compared, and it was found that the drinker group had mean systolic(SBP) and diastolic blood pressures(DBP) 10mmHg higher than the non-drinker group. Nutrient intake levels of the two groups were not significantly different and were adequate with respect to the recommended dietary allowances. It was found that the drinker group ingested more calories, protein, fat and vitamn B1 than the non-drinker group, while the non-drinker group ingested more carbohydrate, calcium, iron, vitamin A, niacin and ascorbic acid. These differences were believed caused by increased caloric intake from alcohol and additional intake of meat served with drinks for the drinking group. Fourteen of the twenty-five drinkers(56%) had drank regularly for five to ten years. Most drinkers drank 2-3 times per week, with alcohol intake less than two bottles(720ml)of distilled liquor(Soju) at a time. Meat was often served with alcohol as reported by 72% of the drinker group, and was believed to contribute to raised intake of calories, protein and fat in this group. Serum lipid levels of both groups were classified as normal, but the components of total cholesterol, triglycerides were significantly higher in drinkers than non-drinkers. The correlation between triglyceride levels and alcohol intake at one sitting was shown to be significantly positive(r=0.57, p<0.01), so it was believed that triglyceride elevation was associated more with heavy drinking than light drinking. We can conclude that if alcohol is consumed with a normal diet, then serum cholesterol, triglyceride and total lipid levels are expected to increase.

Background: Only a few studies directly compared the therapeutic efficacy and safety of two pressurized metered-dose inhalers (pMDIs) in asthma. We analyzed the asthma treatment outcomes, safety, and patient preferences using formoterol/beclomethasone (FORM/BDP), a pMDI with extra-fine particles, compared with formoterol/budesonide (FORM/BUD), another pMDI with non-extra-fine particles. Methods: In this randomized, double-blind, double-dummy parallel group study, 40 adult asthmatics were randomized to FORM/BDP group (n=18; active FORM/BDP and placebo FORM/BUD) or FORM/BUD group (n=22; active FORM/BUD and placebo FORM/BDP). During the two visits (baseline and end of 8-week treatment), subjects were asked to answer questionnaires including asthma control test (ACT), asthma control questionnaires (ACQ), and Quality of Life Questionnaire for Adult Korean Asthmatics (QLQAKA). Lung function, compliance with inhaler, and inhaler-handling skills were also assessed. Results: Ten subjects in the FORM/BDP group and 14 in the FORM/BUD group completed follow-up visits. ACT, ACQ, QLQAKA (a primary outcome), and adverse events did not differ between two groups. We found that the increase in forced expiratory volume in 1 second/forced vital capacity and forced expiratory flow at 25% to 75% of the pulmonary volume in the FORM/BDP group was higher than in the FORM/BUD group. Regarding preference, subjects responded that the flume velocity of FORM/BDP was higher, but more adequate than that of FORM/BUD. They also answered that FORM/BDP reached the trachea and bronchus and irritated them significantly more than FORM/BUD. Conclusion: The use of pMDI with extra-fine particles may relieve small airway obstruction more than the one with non-extra-fine particles despite no significant differences in overall treatment outcomes. Some asthmatics have a misconception about the adequacy of high flume velocity of pMDIs.

Background: Comprehensive medication management is essential to achieve safe and optimal drug use for the elderly in long-term care facilities (LTCF). This study aimed to develop eligibility criteria for "Comprehensive medication management program in LTCF" using the RAND/UCLA Appropriateness Method (RAM). Furthermore, we attempted to estimate the number of beneficiaries who met the criteria by analyzing the National Health Insurance claims data. Methods: Twelve criteria were selected initially. We composed a panel of 14 experts with expertise in long-term care. We conducted two survey rounds to reach a consensus. Rating for appropriateness and decision regarding agreement were applied per RAM. We analyzed the National Health Insurance data to estimate the number of LTCF residents who met each eligibility criterion. Results: Of the 11 items agreed upon, ten items were determined to be appropriate. In 2018, 83.6% of 165,994 residents of LTCF met one or more eligibility criteria. The largest number of subjects met the "New residents of LTCF" criterion, followed by "Take high-alert drugs" and "Chronic excessive polypharmacy." Since the items evaluated as most appropriate by the expert panel and those with a large number of subjects were similar, we confirmed the external validity of our criteria. Conclusion: It is worth noting that this is the first attempt to establish the eligibility criteria for medication management in LTCF. Further preliminary research is needed to identify the selected subjects' drug-related problems and revise the criteria according to the results.
