  • Arterial pulse palpation is an important diagnostic method in Oriental Medicine, particularly for obtaining information about a patient's health conditions or illness, or for confirming a diagnostic conclusion based on the patient's pulsation. The pulse analyzer is both a leading Oriental Medical equipment and a promising tool with such a strong industrial ripple effect that it was selected as one of the four strategic tools for world Oriental Medical instrument market domination at a recent survey. Although various pulse analyzers had been developed, however, most of these were not widely used for clinical diagnosis, due perhaps to lack of the appliance's reliability caused by its inability to reflect the requirements of the clinicians. Thus, in this thesis, the clinical requirements for the pulse analyzer were identified and analyzed by conducting a questionnaire survey among Oriental Medicine clinicians. By looking into the basic functions of a pulse analyzer, the required measurement time, and the medical insurance fee required were determined and among others, the appliance's specific requirements were determined. Moreover, by investigating on the latest patent trend, the technical elements that are needed for the development of a next-generation pulse analyzer were identified. Through these processes, the flow of the technology that must be developed for the pulse analyzer was determined, and the direction for the development of the specific pulse analyzer hardware, sensor, and diagnostic algorithm was identified and proposed.

  • This paper describes the counting-loss problem for radiation measurement Multi-channel analyzers and spectrometers adopt various techniques for compensation for counting-losses in process-ing the radiation pulses from a detector. Researchers hate tried to seek the best solution for the problem. However, any absolute solution has not been reached and vendors of radiation instruments use their own algorithms individually. This survey explains the various compensation algorithms with electronic implementation approach. Shortcomings and merits of each algorithm are also reviewed and a direction is suggested of the recommendable development strategy for counting-loss compensation.

  • The purpose of this study is to investigate the relationship between sleep time and pulse pressure in Korean adults, and the research method used data from the 7th period (2016-2018) of the National Health and Nutrition Examination Survey. Subjects were 5,707 persons aged 20 years or older, and for frequency and percentage continuous data, mean and standard deviation, cross analysis and independent t-test, and stepwise logistic regression analysis for high pulse pressure were performed. SPSS WIN 18.0 version statistical program was used. was used. As a result of the study, the prevalence of hypertension was higher in the overall population (OR=1.344, 95% CI=1.002-1.803) and in women (OR=1.624, 95% CI=1.112-2.371) when sleeping for more than 9 hours compared to less than 6 hours. high, but not significant in males (OR=1.012, 95% CI=0.631-1.550). Therefore, considering the effects of inappropriate sleep time on health, public health education and management are necessary. Further research on the relationship between sleep time and pulse pressure will be needed.

  • In Nan-Gyung, showed that could know the lung condition taking pulse with the weight of three beans, the heart condition taking pulse with the weight of six beans, the spleen condition taking pulse with the weight of nine beans, the liver condition taking pulse with the weight of twelve beans, the kidney condition pressing to bone(骨). This theory is first suggested in Nan-Gyung(難經). In those case, the weight of three, six, nine, twelve beans and pressing to bone don't mean not the real weight but the relative weight(輕重) of taking pulse(按脈). In other words, those represent Boo Jung Chin(浮中沈), which are the conception of the upper, the meddle, the lower part(上中下). So, we could take pulse of the heart and the lung condition in Boo(浮), the spleen condition in Jung(中), and the liver and the kidney condition in Chim(沈). The heart and the lung pulse showed in the Boo(float level) must be seen with Boo-Mack(부맥 : float pulse), the liver and the kidney pulse showed in Chim (sinklevel) must be seen also with Chin-Mack(沈脈 : sink pulse). The result of the method of taking pulse of viscera with relative weight focused on the as pect of mornal pulse(平脈) and disease pulse(病脈) of five viscera in Mack-Gyung publeshed later than Nan-Gyung and special works which made a comprehensive survey the result is as follow. 1. In normal pulse of five viscera, the heart and the lunk pulse were shown with Boo-Mack(浮脈:float pulse) as the central figure, the liver's and the kidney's pulse were shown centering around Chim-Mack(沈脈: sink pulse) and the spleen's pulse was shown with Wan-Mack(緩脈) which is vital force of stomach(胃氣) and seen in only middle part. 2. In disease pulse of five viscera, frequently, the heart and the lung pulse was shown as Chim-Mack(sink pulse), the liver and the kidney pulse was seen as Boo-Mack (float pulse). 3. In the case of normal pulse. the method of taking pulse with relative weight in Nan-Gyung agree with the normal pulse of five viscera in Mack-Gyung. But in the case of disease pulse, they didn't correspond with the other. 4. So the method of taking pulse with relative weight in Nan-Gyung is not the exam pulse which ca be used in the clinical diagnosis but one of the feeling pulse way to bring in the conception of location of the visceras. 5. From now on, the method of taking pulse rdlated to relative weight need to be looked into minutely compared with later physician's theory than Mack-Gyung.

  • To explore college students' course satisfaction over the course of the semester during which a full-scale digital transformation was in progress due to COVID-19 pandemic, this study analyzed student survey data from a university located in the metropolitan area. To minimize the respondents' burden to answer long list of detailed questions in repetition, the study utilized a pulse survey method and students were asked to answer a brief and regular set of online questions 5 times throughout the semester. The number of survey respondents ranged from 1,640 to 4,116, with an average of more than 3,700. The main results and implications of this study are summarized as follows. First, the survey data indicated that the overall student satisfaction with online courses was above average (3.46/5). Vast majority of students have chosen pre-recorded, contents-based course over real-time, video-based course as their preferred course delivery method and this tendency remained the same throughout the semester. Second, the results of keyword network analysis of open-ended questions indicated that technical issues, increased workload (e.g., course assignments and course attendance) were main causes of online course dissatisfaction. And students suggested an unified online course platform and more interactive course design to further improve online courses in the future.

At the time of the development of the pulse meter and analyzer, we put the investigation for oriental medical doctor's demands in practice and found the following results. The development of the pulse analyzer is getting more important for modernization of oriental medicine. The purpose of this study was to find out the research needs for the pulse analyzer considering the practical use in the oriental medical clinics. A survey was conducted at the KIMES 2008 exhibition with a set of questionnaires. We collected the data from 159 oriental medical doctors who attended the exhibition, and we found following results. The more oriental doctors did not think the diagnostic devices were important in their clinical practices. Most responders preferred to use the Chon-Kwan-Cheok pulse diagnosis. To find out the mechanism of the pulse diagnosis and to standardize it, the clinical data base containing the results of the pulse diagnosis and the patten discrimination of each patient should be established. In conclusion, the researches on the standardization of Chon-Kwan-Chuk pulse diagnosis including the measurement techniques and the pulse-pattern correlations are very important for developing the pulse analyzer.
