Purpose : It was to compare changes in respiratory function (pulmonary function, inspiratory function) after four weeks of inspiratory muscle strengthening training (diaphragmatic breathing with upper arm exercise, Power-Breathe breathing) for 36 healthy people. Methods : Subjects were randomly assigned to diaphragmatic breathing with upper arm exercise (Group I) and Power-breathe breathing (Group II) was conducted by the protocol for four weeks five times per week. As the main measurement method for comparison between groups For pulmonary function, Forced Vital Capacity (FVC) and Forced Expiratory Volume at One second (FEV1) were used, and for inspiratory function, Maximum Inspiratory Capacity (MIC), Maximum Inspiratory Pressure (MIP), and Maximum Inspiratory Flow Rate (MIFR) were used. Results : In changes in pulmonary function between groups, FVC and FEV₁ showed no significant difference, and in inspiratory function changes, MIC showed no significant difference, but in MIP and MIFR, Group B significantly improved over Group A. Conclusion : The progressive resistance training using the Power-breath device applied to the inspiratory muscle did not show a significant difference in the increase in the amount of air in the lungs and chest cage compared to the diaphragmatic breathing training accompanied by the upper arm exercise. However, by increasing the air inflow rate and pressure, it showed a more excellent effect on improving respiratory function.

It is possible for humans to breathe underwater using dissolved oxygen. However, unlike fish, humans need large amounts of oxygen to breathe underwater. Water generally contains small amounts of dissolved oxygen. To get enough dissolved oxygen from water, great volumes of it should be supplied into a separation device. If exhalation gases are used, the amounts of water supplied into the membrane can be decreased. However, the characteristics of exhalation gases after passage through the separation device need to be investigated. To reuse the exhalation gases, the concentration of carbon dioxide should be decreased. A compressor is needed to supply the exhalation gases because of the high pressure generated in the membrane inlet. However, compressors require a lot of power and are heavy, so it is not proper to get the portable separation device. A system without the compressor is needed. If the pressure of the position mixed from the exhalation is less than atmosphere, the compressor is not needed. In this thesis, characteristics of the gases which are mixed with exhalation gases and separated from water after passing the membrane are investigated. The compositions of carbon dioxide, oxygen, and nitrogen are measured with the gas chromatography. The effects of water and exhalation gas flow rates on characteristics of gases separated from water after the membrane are showed.

Background: To evaluate the effect of thoracic mobility exercise and deep breathing exercise applied to stroke patients on pulmonary function. Methods: The subjects were divided into two group. Twenty-five patients with stroke were randomly assigned to DB (deep breathing exercise) group (n=13) and TM (combination of deep breathing exercise and thoracic mobility exercise) group (n=12). During four weeks, DB group were carried out deep breathing exercises for 5~10 minutes twice a day and TM Group were carried out deep breathing exercises for 5~10 minutes and thoracic mobility exercise for 20~30 minutes twice a day. All tests were completed before and after experiment. The pulmonary functions were measured by PowerBreathe K5 (Hab International Ltd, England) and tape measure respectively. For each case, the experimental data were obtained in 4 items; average of inspiratory load, inspiratory flow speed, inspiratory flow volume and chest expansion. Results: The results of this study were as follows: 1. In DB group, the statistically significants were shown on average of inspiratory flow speed, inspiratory flow volume and chest expansion (p<.05). 2. In TM group, the statistically significants were shown on all items (p<.05). 3. There was a statistically significant difference on all items between DB group and TM group (p<.05). Conclusions: The above results revealed that DB and TM group can be used to improve pulmonary function in stroke patients. In comparison of DB and TM group, TM group was more improved. In conclude, thoracic mobility exercise helped improving function of vital capacity and chest expansion in stroke patients.

Purpose : This study applies inspiratory muscle resistance exercise with aerobic exercise to smokers and nonsmokers and then determines whether subjects' breathing functions (FVC, FEV1) are increased and how much effect smoking has on the difference in the increase of breathing functions between the two groups. Methods : For this experiment, 26 male adults were selected and randomly allocated to the smoker group (n=13) and nonsmoker group (n=13). The smokers and nonsmokers performed the inspiratory muscle resistance exercise with aerobic exercise three times a week for four weeks. Regarding the breathing functions, the forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were measured three times: week 0, week 2, and week 4. The aerobic exercise was performed using a stationary bicycle with 8 difficulty levels. The inspiratory muscle resistance exercise was performed using Power Breathe with 10 resistance levels. Results : The study found that the FVC and FEV1 values of the smoker group decreased slightly after four weeks of inspiratory muscle resistance exercise with aerobic exercise. In other words, the difference was not statistically significant. In contrast, the FVC and FEV1 values of the nonsmoker group increased by a statistically significant amount. In addition, the intergroup comparison of the average increases in FVC and FEV1 values showed statistically significant differences. Conclusion : The results of this study show that when inspiratory muscle resistance exercise with aerobic exercise was performed, the increase in the breathing functions of nonsmokers was higher than that of smokers. This confirms that, within the parameters of the study, smoking had a negative effect on the increase of breathing functions. This suggests that quitting smoking must be considered as an essential factor when applying a breathing physiotherapy or a breathing function improvement program in clinical settings

영화는 색(色)과 음(音), 그리고 연상 작용에 의한 향(香)을 공감각화한 비쥬얼 스토리텔링이며, 관객이 감각적으로 영화적 사건을 체험하게 한다. 관객은 영화적 이야기에 몰입함으로써 현실세계에서 분리된 객석의 자아를 통해 영화적 세계, 즉 압축된 시 공간의 장(場)에서 억압되고 병치된 인간의 원형적 감정, 쾌락, 공포, 두려움을 재경험하게 된다. 본 연구는 영화 <부러진 화살>을 통해 관객의 쾌감과 두려움의 감정을 볼 것이다. 먼저 쾌감은 니체의 "힘에의 의지"의 관점에서 볼 것이다. 니체는 숨 쉬고, 움직이며, 의지가 있는 것이 살아있는 생명적 존재라고 정의하고, 그것의 동력은 힘에의 의지라고 주장한다. "인간은 힘을 요구하고, 얻고자 하고, 증대시키려 하며 소망한다. 이것이 인간행위와 현상의 원인이다. 또한 인간은 자기보존충동이 있고, 그것은 심적 동기인 쾌감추구로서 작동한다". 우리는 힘의 관점에서 일반적인 심적 동기로서의 쾌감을 <부러진 화살>의 관객의 기쁨과 연계시켜 볼 것이다. 관객은 개념적 약자로서 가난한 자, 여성, 성적 소수자 등등의 도전과 승리에서 자기 보존적 본능을, 즉 쾌감을 느낀다. 이어 관객의 불안, 공포, 두려움의 징후들을 라캉의 정신분석학에 나오는 '아버지의 이름 Name-of-the-Father'의 관점에서 분석할 것이다. 라캉은 프로이트의 이드, 자아, 초자아의 개념을 실재계, 상상계, 상징계로 확장하고, 이 계(界)들 가운데 상징계(질서세계)에서 '아버지의 이름'을 언급한다. 익히 알려진 것처럼 소쉬르가 "일반 언어학 강의"에서 언어의 기본적 구조로서 기표와 기의를 규명하였고, 이에 근거하여 라캉은 '아버지의 이름'을 사회화의 기본적 기표로, 그리고 연결장치로서 제시한다. 아버지의 이름은 법의 상징이자 은유로서, 그의 부재와 그에 대한 항거는 사회의 불안으로 직결된다. 마지막으로 자기 보존적 본능에서 촉발되는 저항의 쾌감과 법(질서)의 부재에서 오는 두려움, 이러한 본래적 감정이 진보와 보수의 가치관에 연계되어 있음도 함께 고찰하고자 한다.
