Background : Respiratory muscle weakness has serious clinical consequences. Vital Capacity is the volume of air that is normally exchanged in a single breath. It varies widely with pulmonary health and overall fitness. Purpose : The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of Kinesio taping and balloons blowing. Methods : Twenty-one non-smokers were participated in this research and these subjects were randomly assigned into three groups; a balloons blowing group(n=7), a Kinesio taping group(n=7), and a balloons blowing and Kinesio taping group(n=7). This experiment was done from June 22, 2009 to July 5, 2009. In order to measure the VC variation effects of Kinesio taping, balloons blowing, and both intervention, an windmill type spiropet was used. The collected data were analyzed statistically by using a paired t-test and ANCOVA. Results : The results of this study were as follows; 1) In the case of balloons blowing, there was a significant difference, 3.35% increase of VC, between before and after 2 weeks experiments(p<.01). 2) In the case of Kinesio taping, there was a significant difference, 11.66% increase of VC, between before and after 2 weeks taping intervention(p<01). 3) In the case of both balloon blowing and Kinesio taping, there was a significant difference, 15.84% increase of VC, between before and after 2 weeks both interventions(p<.01). 4) After 2 weeks experiment, the improvement of VC was shown a significant difference with intergroup(p<.05). Conclusion : From these results, it was revealed that balloons blowing or Kinesio taping, or both interventions were effective to improve VC of healthy adults.

Asbestos is widely used in the textile, asbestos cement, construction products, friction material, paper products, insulation products, chemical and plastic products because of its heat resistance, flexibility, tensile strength, and texturability. It is now generally recognized that longterm and excessive inhalation of asbestos dust causes asbestosis, lung cancer, malignant mesothelioma and malignancies in other organs such as cancer of gastrointestinal tract, leukemia, lymphoma. Although eighty thousand tons of asbestos has been annually consumed since 1979 in korea, it has not been reported asbestos and lung cancer by asbestos dust so far, while a case of mesothelioma was officially diagnosis as a occupational disease at 1993. We experienced firstly a case of asbestosis and lung cancer caused simultanously by occupational asbestos exposure 11 years, which was confirmed by chest x-ray, pulmonary function test, chest CT and HRCT, bronchoalveolar lavage, and gallium scan. And so We present a case of asbestosis, pleural effusion and lung cancer with a review literature.

Objective: The purpose of this study was to assess the effect of hospital-based pulmonary rehabilitation (PR) on exercise capacity and quality of life as well as barriers to participation in persons with chronic obstructive pulmonary disease (COPD) in South Korea. Design: One-group pretest-posttest design. Methods: A total of 14 patients were enrolled in this study in an 8-week PR program with two 60-minute sessions per week. The program included: flexibility exercises, breathing techniques, strengthening exercises, and aerobic exercises. The outcomes were defined as changes in the variables before and after the PR program. A change in the 6-minute walk distance (6MWD) was defined as the primary outcome, and changes in pulmonary function test, respiratory and grip strength, and the St. George's Respiratory Questionnaire (SGRQ) about quality-of-life results were secondary outcomes. A dropout was defined as missing >3 of the 16 sessions. Results: Patients who completed the program showed a significant improvement of 43.57±39.43 m in the 6MWD (p<0.05), but no significant differences were noted for the other function tests. The SGRQ showed a significant improvement in the activity and total score (p<0.05). The total dropout rate was 53.3%. Newly developed symptoms, exacerbation of COPD, transport problems, and lack of motivation were major barriers to PR. Conclusions: Our study showed that an 8-week hospital-based PR program improved exercise capacity and quality of life but had a high dropout rate in individuals with COPD. Since comprehensive PR has only recently been established in South Korea, patient motivation and education are critical.

The purpose of this study is to evaluate the physical fitness status and health promoting life styles of the workers. For the purpose, 108 workers who attended the exercise program in Inchon branch of KISCO were selected as the subjects. From Oct. 20th to Nov. 30th, in 1998, they were firstly assessed their physical fitness. The items include cardio-respiratory endurance, flexibility, muscular strength, muscular endurance, agility, power, balance, body composition, etc. Secondly, the health promoting life styles were asked by questionnaires about daily life and dietary habits. Both of them were evaluated by 5 or 3 levels as A(very good) to E(very poor) or A (good) to C(poor). Those data were analyzed percentile, mean, standard deviation by SAS program. Major findings are as follows ; 1. The health promoting life styles were generally good, but 43.5% of the subjects didn't exercise at all. Most of them(93.5%) thought about their physical fitness status as lower than average level. About half of them(48.1%) didn't drink alcohol, non smokers were 70.4% of them. But they had poor dietary habits(lower than average level : 79.6%), females were a little bit better than males. The aged group had the poor body compositions, 21.4% of females and 10.0% of males were obese. 2. Physical fitness status of the workers were assessed as two areas, one is health related, the other is physical function related area. In the health related area, females were better than males, in view of age, forties aged group had the highest scores of all items except cardio-respiratory endurance. Among 'A' and 'B' level, muscular endurance was showed most frequently, followed by muscular strength, flexibility, cardiorespiratory endurance. In physical function related status, balance was ranked highly in the portion of over 'B', followed by power, agility. In view of sex, males were better than females for all items except balance, and there were various figures in the status by age groups. 3. Comprehensive assessment scores were poor(under 'D' leves were most frequent), females were better than males, and teenage group had the worst scores. In ages of the physical fitness, generally they had 1 year under their real ages, and females were better than males. In view of age, forties aged group was ranked highly and teenagers had lowest scores.

The purpose of this study was to identify and analyze the rate of change of air respirator consumption based on field fire fighting activities, The results of the experiment are as follows. The mean air consumption of the Five subjects was $15.56{\ell}/min$ when standing still, $32.43{\ell}/min$ when walking with normal pace, $43.07{\ell}/min$ when the fire hoses was expanded and arranged, $55.28{\ell}/min$ when climbing stairs, The situation of running up the stairs and hitting the hammer continuously increases to $127.14{\ell}/min$, which means that the consumption of air increases according to the energy consumption. Despite being the oldest, Experimental subject A was $13.23{\ell}/min$ when standing still, $29.33{\ell}/min$ when walking normally, and $41.08{\ell}/min$ when the fire hose was deployed and arranged. This is a result of familiarity with deep and slow breathing methods. The average respiratory use rate of subjects D was $63.58{\ell}/min$. The reason for this is that obesity seems to increase the air consumption, and it is considered that the physical strength is exhausted by the action of the hammer, which has a greater influence on the increase of air consumption. The subject E had significantly lower air respiratory use rate of $49.90{\ell}/min$. The reason for this is that the age of E is the youngest among the subjects, and it is presumed that it possesses strong physical strength.

A 3-year-old, spayed female Shih-tzu dog was presented due to acute vomiting, diarrhea, and generalized weakness. The dog had generalized weakness, increased respiratory rate, and respiratory muscle effect. Neurologic examination revealed appendicular muscular weakness and decreased in tone of the anal sphincter. Megaesophagus was confirmed by radiographic examinations. Other than type 2 fiber atrophy, no specific abnormalities were identified in histopathologic examinations of muscle biopsies from the left pelvic limb. Serum acetylcholine receptor (AChR) antibody titer was increased (0.78 nmol/L reference range, less than 0.6 nmol/L), confirming a diagnosis of acute fulminating myasthenia gravis. The dog dramatically responded to pyridostigmine bromide and had marked improvement in muscle strength, megaesophagus, and respiratory function. The dog has been successfully managed for 7 months after initial treatment.

The effects of inspiratory muscle training in conjunction with aerobic exercise on inspiratory muscle strength, pulmonary function, and maximal oxygen uptake(VO₂max) were examined. Twenty four healthy collegiate men were divided into three groups; respiratory muscle training group(RTG; n=8), running exercise group(REG; n=8), and both respiratory muscle training and running group(BTG; n=8). Their pulmonary function, maximal inspiratory pressures(PImax), and VO₂max were assessed before and after intervention. RTG underwent inspiratory muscle training(IMT) with load set to 50 % of PImax, 30 times per session, twice a day, 4 days a week REG ran on a treadmill at 70-75 % of VO₂max for 30 min a day, 4 days a week. BTG participated both IMT and the running exercise. Participant's anthropometric parameters and pulmonary function were not changed. VO₂max increased by 6.1±3.3 %, 5.9±6.6 %, and 10.0±8.3 % in RTG, REG, and BTG, respectively(p< .05), and PImax also increased by 21.7±14.3 %, 19.7±12.0 %, and 27.0±12.1 % in RTG, REG, and BTG, respectively, but no group differences were found. Based on the study, although statistically insignificant, BTG showed the biggest increase of VO₂max and PImax indicating a possible synergic effect of inspiratory muscle training and aerobic exercise on respiratory responses.

The effect on strength and endurance training (SET) (2 patients) were compared with those of strength training(ST) (2 patients) in patients with-chronic obstructive pulmonary disease. The result of training was assessed by 4 tests: maximal inspiratory pressure(PImax), sustainable inspiratory pressure (SIP), maximal voluntary ventiiation(MVV) and bronchitis-emphysema symptom checklist(BESC). Measurements were repeated before and after training per week for 6 weeks. The SET group performed inspiratory muscle training, using a inspiratory muscle trainer 30 minutes per day, 6 days per week and performing endurance training-12-minute walking-2 days per week for 6 weeks, whereas the ST-only group trained for 30 minutes daily, 6 days per week using inspiratory muscle trainer. SET was no significant increase in exercise performance, whereas ST produced an increase in SIP and a decrease in BESC. There was significant change in BESC betweet the two groups. A simple at home training program using inspiartory muscle trainer was more effective than that of SET program in improving exercise performance of some patients with COPD.h COPD.

The aim of this document is to evaluate the effect of bite balance on physical fitness and motor capacity to determine the importance of the occlusal stability as a possible action mechanism of occlusal appliance including mouthguards on physical performances. We all remember that day when the prominent athlete was in the news wearing a mouthguard to improve human athletic performance. I once had investigated the determinants of athletic performance in all sorts of sports. Most of the studies had overinterpretation of results and lack of evidence to support the information. However, I discovered great expectations for new possibility in this field and settled for a more academic approach to this intriguing subject. The followings are some examples of the subject 1. Archers who wore occlusal appliances to increase the vertical dimension of occlusion by 2~3mm increased their ability to focus and to maintain good sense of balance. Their accuracy rate has been improved. The appliance was made of acrylic resin (a type of plastic). 2. Canoe players who wore occlusal appliances to increase the vertical dimension of occlusion by 5mm surpassed longtime competitor and won the race with 10 seconds gap. 3. A cycle rider who wore an occlusal appliance to treat his malocclusion surpassed his old record from 10.8 seconds to 10.3 seconds. His muscle reflexes (anaerobic exercise) and endurance (aerobic exercise) has been enhanced. 4. Occlusal appliances had a good effect on athletic performance in most sports such as swimming, diving, and weightlifting. As for the clenching on dentition, people clench their teeth when they push their physical and mental limits during sports activities. Clenching can be induced by physical exertion when maximum muscle strength is retained and this is similarly found in different types of exercises. In addition, restraint of respiratory function is observed. Therefore, creating a occlusal balance with occlusal appliance or mouthguard promoted a favorable influence when an athlete clenches.
