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

Movie captured audience's whole sense organs to the screen which is made up of visual story-telling decorated by color, sound, and smell. The audience rediscovered native emotions(pleasure, fear, terror) suppressed and left in the compressed world of space and time, that is to say a movie world separated from the real world, by being immersed in the movie story. This study revealed audience's feelings of pleasure and fear by analyzing the movie . First of all, the pleasure would be discussed in terms of Nietzsche's "the will to power." Nietzsche defined something to breathe, move, and will as being alive, and he insisted that its power to life is 'the will to power.' Human beings wish to have power and want to increase it: pleasure, the real motivation of human behaviors and phenomena. The movie well revealed the pleasure by showing nonperson's challenge and victory against social rulers. Second, the fear and terror of the audience will be discussed in terms of in Lacan's psychoanalysis. Lacan extended Freud's id, ego, and superego into the worlds of reality, imagine, and symbol, and suggested a father in symbol world among those worlds. He suggested as a basic and connecting instrument of the socialization just like Signifi$\acute{e}$ and Signifiant, Saussure' basic linguistic structure in "Cours de lingustique g$\acute{e}$n$\acute{e}$rale"(1916). Because father is the symbol and the metaphor of law, the absence of him and resistance against him means obstacles of social stabilization. Finally this paper will also discuss that the fear from the absence of law and the pleasure provoked by self-preserving instincts, that is to say natural feelings, are connected to values of progressivism and conservatism.
