  • Jigam(止感), Josik(調息), Kumchock(禁觸), from the lecture on Truth of ${\ll}Samilshingo{\gg}$(三一神誥) treat three elements of Kigong, regulation of mental activties, regulation of breathing and adjustment of posture and there are some similar mentions with the view of human body based on oriental medicine like those Samjin(三眞), Sammang(三妄), Samdo(三途) and Sippalkyoung(十八境) ect. Thus as a result of comparison and observation about the interrelationships between principle of Kigong in the lecture on Truth of ${\ll}Samilshingo{\gg}$(三一神誥) and oriental medicine. I have conclusion as follows. 1. According to the lecture on Truth, the components of human body are the one and only Samjin(三眞), Sammang(三妄) and Samdo(三途) resulted from facing Samjin(三眞) to Sammang(三妄) and Sippalkyoung(十八境). This fact presents the principle of human change. 2. the principle of Kigong mentioned in the lecture on Truth shows the original Ilshin(一神) on the basis of Samjin(三眞), Sammang(三妄), Samdo(三途) and Sippalkyoung(十八境). This makes common, unity and sound Sim(心), Ki(氣) and Shin(身), Sammang(三妄) through Jigam(止感), Josik(調息) and Kumchock(禁觸), be versed, intellected and guaranteed Sung(性), Myoung(命) and Jung(精), Samjin(三眞) and emit Kyun(見), Mun(聞), Ji(知) and haeng(行), Sadaeshingi(四大神機) and finally all these are harmonized into Duk(德), Hye(慧) and Ryuk(力), Samdae(三大) which is the entity of God. 3. Samsipyookjongmyowhasang(三十六種妙化相) is an ascetic practice done after a chulin(哲人) deduce Ji(止), Jo(調) and Kum(禁), Sambup(三法) on the basis of the lecture on Truth. So I suppose it correlates nature's six elements. Kong(空)(Chun(天)). Yol(熱)(Wha(火)). Jin(震(Jeon(電)), Seup(濕)(Shoo(水)), Han(寒)(Poong(風)) and Ko(固)(Ji(地)), human's Samjin(三眞), Sung(性), Myoung(命) and Jung(精) and Sammang(三妄), Sim(心), Ki(氣) and Shin(身) and makes clear the principle of discipline. 4. In comparison with Samjin(三眞) and Sammang(三妄) says from the lecture on Truth and the Three Essential Elements of the body construction(三寶) from oriental medicine, Samjin(三眞) and Sammang(三妄) as factors of human body in the concept of practical knowledge. That is the one and only Samjin(三眞) in terms of the Three Essential Elements of the body construction(三寶) is considered a structural principle for every single person and Sammang(三妄) is considered a functional form for each individual. And it can be Sung(性)+Sim(心)=Spirit(神), Myoung(命)+Ki(氣)=Vital Force(氣) and Jung(精)+Shin(身)=True Essence(精). 5. In comparison with Sippalkyoung(十八境) of Samdo(三途) from the lecture on Truth and three medical causes of disease, Gamdoyookkyoung(感途六境) is similar with endopathic cause caused by Naesangchiljung(內傷七情), Sikdoyukkyoung(息途六境) is similar with exopathic cause by six climatic conditions in excess as pathogenic factors(六淫) and Yoegi(?氣) and Chokdoyukkyoung(觸途六境) is similar with non-endo-exopathogenic causes by diet imbalance, fatigue, intemperance in sexual life and trauma etc. 6. In the lecture on Truth, the Chulin(哲人) who discipline Sambup(三法), Sangchul(上哲), Choongchul(中哲) and Hachul(下哲) can be compared with Kigong expert(health preserving expert) such as the Spiritual Men(眞人), the Sapients(至人), the Sages(聖人) and the Men of Exellent Virtue(寶人) in the Sang Gu Tian Zhen Lun of the Huang Ti Nei Ching Su Wen(素問 上古天眞論) and then Sangchul(上哲) is the Spiritual Men(眞人), Choongchul(中哲) is the Sapients(至人) and Hachul(下哲) is the Sages(聖人) while the men of Exellent Virtue(賢人) is inferior to Chulin(哲人) when he goes to extremes.

  • Thanks to mass production and provision of smartphones and the HMD (head mounted display), VR (virtual reality) is now being applied to various areas. The VR HMD is the interface equipment which allows users to have realistic experiences through human sensory organs such as vision and auditory sense. Since the majority of VR equipment is operated by the display for both eyes, 360-degree video content and the depth information, the VR mechanism is closely related to human senses, especially vision. Previous studies have focused on how to minimize negative impact such as motion sickness or visual fatigue. Little attention has been paid on research about the visual treatment. Therefore, the focus of this study is to develop technical elements for utilization of vision therapy with the VR HMD and explore possible areas to apply it. To this end, we analyzed the past case studies and technical elements to identify 16 areas for vision therapy. We also developed the optical parameters for utilization of the VR HMD visual targets. The result of this study is expected to be utilized for development of visual targets for vision therapy based on the VR HMD.

  • This study examined energy saving and elevating the worker's neuro energy (comfort, concentration, physical, and psychological stability) by compensating for the unpleasant tactile sensation to stimulate auditory and olfactory senses and reduce energy consumption. The experiment was conducted in an environment test room under the test conditions of temperature $25[^{\circ}C]$, relative humidity 50[RH%], illumination 1,000[lux] and air current speed 0.02[m/sec] by stimulating the auditory senses with a 1/f change in rhythm and the olfactory senses with an aroma scent. The experiment utilized the method of EEG, which evaluates human body's psychological status via tactile means, and the method of the vibra image, which evaluates the learning abilities, HRV and human body's psychological status via non-tactile means. The subjects were selected as eight university students (four males and four females) in their 20s, the type that have high relative ${\alpha}$(8~13[Hz]) activation in occipital lobe, which brings the highest level of mind stability and concentration, who had no difficulty in physical activities. The subjects' posture and physical activity was fixed to 1met - when the subjects are seated and relaxing in a comfortable environment - and their clothes condition was standardized as 0.7clo. As a result, the sentimental and psychological stability and concentration were the highest in the multisensory stimulation of jasmine scent and change rhythm of an a=1.106 sound source. In addition, under this condition, the relative $M{\alpha}$ and relative $M{\beta}$ increased by 70.49[%] and 89.72[%], respectively; the HRT decreased by 39.09[%]; and the fatigue and tension/anxiety decreased by 36.85[%] and 15.54[%], respectively.

  • PURPOSE: The study aimed to analyze the effect of pillow height on upper trapezius and sternocleidomastoid (SCM) muscle activity and overall human body comfort to determine the optimal pillow height. METHODS: The study included 32 healthy college students, of both genders, who provided prior consent. It examined three pillow heights (flat, 6cm, 12cm) and measured the upper trapezius and SCM muscles using ultrasonography, myotone, and electromyography(EMG). Muscle activation, thickness, and fatigue were assessed. RESULTS: The study found significant differences in muscle thickness and muscle tone based on the pillow heights (flat, 6cm, and 12cm) with a p < .05. The SCM and upper trapezius muscles were thinnest at a pillow height of 6cm. Muscle tone in the SCM was lower at both 6cm and 12cm pillow heights. Post-hoc measurements showed significant differences in both the SCM and upper trapezius muscles thickness at the 6cm pillow height (p < .05). Also, significant differences in muscle tone were observed only in the SCM, particularly between the 6cm and 12cm pillow heights. CONCLUSION: The ultrasonography and myotone measurements showed a significant difference in muscle thickness and muscle tension, both of which were above 6cm, while there was no difference in muscle activation. Based on the strong correlation between muscle tension and muscle thickness with pillow height, this study concluded that the human body feels comfortable with a 6cm pillow height. Therefore, it is recommended to use a pillow height of 6cm when lying in a supine position.

  • The purpose of this study was to identify the factors related to allergic diseases based on the health behavior of the youth in multicultural families according to the data from Tenth Korea Youth Risk Behavior Web-Based Survey 2014 (Centers for Disease Control & Prevention). The subjects from 712 multicultural adolescents were analyzed by the SPSS program. For the characteristics of health behavior of the multicultural youth, 267 students (37.5%) have experienced drinking alcohol, 164 students (23.0%) have experienced smoking, and 35 students (4.9%) have experienced taking drugs. Also, 198 students (27.8%) were depressed, 259 students (36.3%) are suffering from stress, and 286 students (40.2%) failed to fully relieve fatigue. In addition, 497 students (69.8%) consider themselves as healthy, 449 students (63.1%) consider themselves as happy, and 251 students (35.3%) consider themselves as overweight. Among the allergic disease of the multicultural youth, 46 middle school students (6.5%) and 35 high school students (4.9%) have asthma, 95 middle school students (13.3%) and 87 high school students (12.2%) have allergic rhinitis, and 67 middle school students (9.4%) and 53 high school students (7.4%) have atopic dermatitis. 47 male students (6.6%) and 34 female students (4.8%) have asthma, 81 male students (11.4%) and 101 female students (14.1%) have allergic rhinitis, and 53 male students (7.4%) and 67 female students (9.4%) have atopic dermatitis. Among the multicultural youth, 81 students (11.4%) have asthma, 182 students (25.5%) have allergic rhinitis, and 120 students (16.8%) have atopic dermatitis. For the allergic diseases from the health behavior of the multicultural youth, depression (p<0.001), alcohol experience (p<0.05), drug experience (p<0.05), health recognition (p<0.05), happiness recognition (p<0.05), and body type recognition (p<0.05) had a statistically significant relationship with asthma. Fatigue recovery recognition (p<0.001), health recognition (p<0.001) and stress recognition (p<0.05) had a statistically significant relationship with allergic rhinitis. Body type recognition (p<0.01), depression (p<0.05), fatigue recovery recognition (p<0.05), health recognition (p<0.05), and happiness recognition (p<0.05) had a statistically significant relationship with atopic dermatitis. Such results show that schools and society need to educate the multicultural youth about health, happiness, and body type recognition which are big factors of allergic diseases. Schools and society also need to be more systematic and continuous in order to help multicultural youth to be have correct recognition of depression, stress and fatigue recovery.

The chief complaint was mainly categorized by oral examination on patients and their care-givers. Result 1. The numbers of children who involved in this study is total 1245: Male children are 668 and female children are 577 children. The sex rate between male and female is 1.15 to 1. 2. Most of the above patients came to the hospital at first time from diseases such as musculoskelectal disease, weakness, asthma, cough, anorexia, common cold, rhiorrhea, sweating, dyspepsia, dematitis, night terror, obesity, stomach, short stature, Besides, they also came to the hospital at first time from various diseases such as epistasxis, pyrexia. Bell's palsy, nocturia, contipation, cerebral palsy, disorder, CVA. diarrhea. stress disease, Allergic disease, Tic disorder. Visual disorder, Kawasaki disease, Pierre Robin's syndrom, hematuria, edema and so on. 3. Looking at the frequent diseases, Respiratory dis. children including asthma, cough, rhiorrhea, sweating, common cold, pyrexia covers 36%, in 399 numbers. digestive dis. children including anorexia, dyspepsia, stomach, diarrhea, constipation, indigestion covers 19%, in 211 numbers. cadiovasculary disease children including arrthymia, terror in frequency, night crying, sediation, Tic disorder covers 8%, in 85 numbers. Hepatobiliary disease children including short stature, dizziness, visual difficulty, sprain, disorder of nail covers 21%, in 238 numbers. renal disease. children including nocturia, hematuria, hemation, disorder of hair, menorrhea, cerebral palsy, edema in 44 numbers. Fatigue children covers 13%. in 143 numbers. 4. In case of respatory disease children. total number is 399 children. dematitis children are 108 numbers and asthma children are 96 numbers. These show that children seem to the best have dematitis and asththma. The age from 0 to 6 is 290 numbers, covering 73 percentage. The others are covering 27 percentage. These data demonstrate that the age from 0 to 6 age could easily get these kinds - of diseases. The 29 percent of children had these kinds of diseases in spring. The 28 percent of children had these kinds of diseases in autumn. These show that children seem to frequently have these kinds of diseases in both spring and autumn season.(inter-season) 5. In case of digestive disease, anorexia covers 39%, in 83 numbers, dyspepsia covers 28%, in 59 numbers, anorexia and dyspepsia were the lagest group in digestive disease and the age from 0 to 6 covers 59%, in 125 numbers and the other age covers 39%. According to these data, infant seems to be vulnerable to these kinds of diseases. The 24 percent of children had these kinds of diseases in spring and summer. The 33 percent of children had these kinds of diseases in winter, which means that children mostly had winter. but decreased significant in autumn. 6. In case of cadiovasculary diseases, it can be divided into two categories: night covers 73% and nervous characteristics covers 27%. The age from 0 to 6 occupies 75%, and the other age occupies 25%. These data also show that infants can easily infected with these kinds of diseases. Analyzing by the season, summer could be the most frequent season that children have these kinds of diseases. but decreased in autumn. 7. In case of hepatobiliary children, sprains covers 166 numbers, fatigue covers 32 numbers, epistasxia covers 24 members, the reasion which sprain occupyied most of % were sprain covered ages.

  • Recently, the rate of cesarean section in Korea has been increasing. The results of several previous studies in foreign countries on the emotional responses of cesarean section mothers showed that they might experience difficulties in the mother- infant interaction due to fatigue, lack of early mother - infant interaction, disappointments, anger, feelings of loss of control, and other factors. Human behavior is said to be determined by one's self concept, and self concept is influenced by both internal and external environmental factors. A scale to measure the self concept of cesarean section mothers was needed in order to identify those who might have difficulties in the mother- infant interactions in future. The purposes of this study were to develop a measuring scale, and to test its reliability and validity. The process of this study was as follows. A structured interview was done with 50 cesarean section and vaginal delivery mothers to find their state of emotional reaction after giving birth to their babies. Based on the results of the interviews, a 50 items Likert scale was developed. The self concept of 268 cesarean section and vaginal delivery mothers who were hospitalized at six hospital in seoul were measured, during the period between Feb. 1 and April 30. Reviewing the discriminating power of each item by means of crosstabulation, ten items were selected for the final scale. The reliability and validity of this ten item scale were tested by Cronbach's alpha and t-test, using spss pc+package. The results of this study and recommendation are as follows. 1. The ten selected items were as follows. I feel pains in my breast. (-) I have a good appetite now. (+) I feel pains in my flank. (-) I feel fine now. (+) My body seems to have returned to its prepregnant state. (+) Thinking of the delivery process, I feel sorry. (-) I want to hold my baby in my arms. (+) I want to keep my own life, even if I became a mother. (-) I want to delegate the care of the baby to my mother / mother in law. (-) I think baby is my alter ego. (+) 2. The reliability of this scale was tested by Cronbach's alpha, and the coefficient of this scale was .8066. 3. The construct validity of this scale was tested by means of known group methods. The value of self concept for cesarean section mother was significantly lower than for vaginal delivery mothers(t=-5.51, df=266, p=0.007). 4. The criterion validity of this scale was tested indirectly. Though this scale could discriminate the differences in the self concept between cesarean section and vaginal delivery mothers, the five items on the personal self concept scale didn's show any differences between cesarean section and vaginal delivery mothers. Therefore, the study indicates that those who shows lower values in the personal self concept measurement, that is, lower than 12.03 points, could be regaled as “risk mothers” 5. Further studies using this scale to clarify the influencing factors on negative self concept are strongly recommended.

  • Depth map upsampling is an approach to increase the spatial resolution of depth maps obtained from a depth camera. Depth map quality is closely related to 3D perception of stereoscopic image, multi-view image and holography. In general, the performance of upsampled depth map is evaluated by PSNR (Peak Signal to Noise Ratio). On the other hand, time-consuming 3D subjective tests requiring human subjects are carried out for examining the 3D perception as well as visual fatigue for 3D contents. Therefore, if an objective metric is closely correlated with a subjective test, the latter can be replaced by the objective metric. For this, this paper proposes a best metric by investigating the relationship between diverse objective metrics and 3D subjective tests. Diverse reference and no-reference metrics are adopted to evaluate the performance of upsampled depth maps. The subjective test is performed based on DSCQS test. From the utilization and analysis of three kinds of correlations, we validated that SSIM and Edge-PSNR can replace the subjective test.

  • Many domestic users complain about severe pain to the waist, neck, and shoulder as well as work performance because the domestic chair design was developed with western anthropometry dimension and design criteria. Ergonomic design standards are needed for office chair design to reduce stress and poor physical posture for various user body types. In this study, we have suggested design dimensions recommended from previous studies and Korean anthropometry data. We also have reviewed users' preference dimension through measured subjects and analyzed differences between users' preference dimension and the previous design criteria to verify physical appropriateness. We evaluated general office chairs and adjustable chairs which can adjust to fit each person. we also analyzed how each design dimension was reached and affected the human body by evaluation of physical discomfort and comfort. We have found seat height is very important in a workstation. If the seat height is high, it effects the thigh. If width, height, and angle of the backrest are wrong, fatigue to the shoulder, neck, and waist, etc.. As a result of this experiment, we suggested that the height of a seat for Koreans be 425mm for the fixed type and 365-484mm for the adjustable type. Also other design recommendations were suggested in the thesis. In conclusion, our research will be very important in the database because it provides adjustable ranges to fit user's body types in the various design fields.
