Subjective oral health status authoring feel healthy food disorders, toothache, periodontal problems, tmj pain, dry mouth, bad breath symptoms such as 'sometimes' 'often' than a 'no' if you appear to be a highly subjective and social efficacy Efficacy of oral health status and social influence were more (p<0.01). 2. Subjective oral health status of the seven kinds of sub-variable that oral health status, food authoring disorders, toothache, gum disease, jaw joint or more, dry mouth, bad breath instantly and look at the relationship between social efficacy oral health status, ability of mastication, pain in oral, gum disease, tmj pain, dry mouth, presence of halitosis than positive (+) was correlated.

  • We suggest a CNT-based gas sensor for breath alcohol measurement. The sensor was composed of single-walled carbon nanotubes (SWCNTs) thin film on flexible PES (polyethersulfone) substrate, and the SWCNTs thin film was formed by multiple spray-coating with SWCNTs solution which was well-dispersed, highly controlled and functionalized in ethanol solvent. In this work, three types of SWCNTs thin films were deposited with changes in the number of spray-coatings to 20, 40 and 60 times in order to compare electrical response properties of the SWCNTs thin films. from the fabricated sensors, conductance and capacitance responses were measured and discussed. Alcohol gas sensors have been commercialized widely as gauge for breath alcohol measurement which is applicable to checking whether car drivers are drinking-driving or not. Our alcohol gas sensors showed good sensitivity and linearity even at room temperature.

  • Based on the results of studies on acetone excretion in diabetic patients, a one - chip sensors array was fabricated by combining acetone-selective sensor materials and volatile-organic-compound sensitive sensor materials. An electonic-nose was implemented using a sensor array and confirmed selectivity for five gases. In this system, the excretion of diabetic patients and controls was sampled with solid phase microextraction fiber and transferred to the sensor array. Although the control and diabetic patients were distinct, several samples failed. In the control group, the results of blood tests were normal, but patients were highly obese. In addition, the gas chromatography mass spectrometry results for the subjects revealed chemicals that are external factors.

  • Authors have selected a physiological bad breath patient( 62 years old, male ) among the bad breath outpatients who have visited the halitosis control clinic in Korea University Medical Center(KUMC). The patient visited the halitosis control clinic for his oral malodor control, 3 times from April to June in 2018, and in August the patient visited to KUMC malodor control clinic again for his assessment of his two months efforts. Getting the data about the patient's endeavor to get over his physiologic oral malodor and the estimation of the patient's satisfaction level at his oral malodor improvement by a questionnaire method, and the organoleptic level assessment by the dentist, then we could propose an estimation method of the physiologic oral malodor patient care prognosis.

  • The aim of this study was to raise awareness about smoking and to facilitate the induction of smoking cessation. The participants were 49 patients who showed intention to participate in the test. The participants who had done a questionnaire, were asked to quit smoking for about an hour. After taking the breath deeply, they stopped for 20 seconds and measured breathing slowly. Carbon monoxide in the exhalation was higher when the daily smoking amount was higher and the smoking duration was longer, but not significant. In the case of smoking after meal and smoking in bed in the morning, the carbon monoxide level was significantly higher than that in the case of not smoking. It was significantly associated with skin allergic symptoms. The usual exercise habits, drinking and the respiratory disease were not correlated with carbon monoxide levels.

  • Purpose: To quantify the cardiac dose reduction during breathing adapted radiotherapy using Real-time Position Management (RPM) system in the treatment of left-sided breast cancer. Materials and Methods: Twenty-two patients with left-sided breast cancer underwent CT scans during breathing maneuvers including free breathing (FB), deep inspiration breath-hold (DIBH), and end inspiration breath-hold (EIBH). The RPM system was used to monitor respiratory motion, and the in-house self respiration monitoring (SRM) system was used for visual feedback. For each scan, treatment plans were generated and dosimetric parameters from DIBH and EIBH plans were compared to those of FB plans. Results: All patients completed CT scans with different breathing maneuvers. When compared with FB plans, DIBH plans demonstrated significant reductions in irradiated heart volume and the heart $V_{25}$, with the relative reduction of 71% and 70%, respectively (p < 0.001). EIBH plans also resulted in significantly smaller irradiated heart volume and lower heart $V_{25}$ than FB plans, with the relative reduction of 39% and 37%, respectively (p = 0.002). Despite of significant expansion of lung volume using inspiration breath-hold, there were no significant differences in left lung $V_{25}$ among the three plans. Conclusion: In comparison with FB, both DIBH and EIBH plans demonstrated a significant reduction of radiation dose to the heart. In the training course, SRM system was useful and effective in terms of positional reproducibility and patient compliance.

  • Objective : Sensory integration is the organization for sensation for use. The purpose of this study is to carry out the sensory integrative intervention for the mental retardation with child and to examine change of child's balance and breath abilities. Methods : The study performed from 25 May to 13 Autumn, 2009. The design is AB design(baseline 3sessions, intervention 21sessions) of single-subject research design. We carried out the sensory integrative intervention(3 sessions per week) for baseline period and the sensory integrative intervention(3 sessions per week) with sensory diet every day for intervention period. Results : The results of the sensory integrative intervention with sensory diet had positive effects for child's breathe and balance. Conclusion : The occupational therapists recognize the effects of the sensory integrative intervention with sensory diet and need to recommend for the family of child with disability.
