최승훈 한국기계기술학회 2021 한국기계기술학회지 Vol.23 No.2

These days, our environmental pollution has been greatly threatened by various exhaust emissions from diesel engines for transportation, and there is a tendency that regulations on this are very strengthened. In this study, when biodiesel and water-cooled EGR are simultaneously applied to common rail diesel engines, which occupy most of passenger diesel engines, the characteristics of exhaust smoke and NOx were investigated. As a result of this experiment, as a result of applying less than 10% EGR to 5% biodiesel mixed fuel, it was found that smoke and NOx emissions can be simultaneously reduced.

This paper presents a new prototype of an engine mount for a passenger vehicle featuring ER(elector-rheological) fluids and piezoactuators. Conventional rubber mounts and various types of passive or semi-active hydraulic engine mounts have their own functional aims on the limited frequency band in the board engine operating frequency range. However, the proposed engine mount covers all frequency range of the engine operation. A mathematical model of the proposed engine mount is derived using the bond graph method which is inherently domain, the ER fluid is activated upon imposing electric field for vibration isolation while the piezoactuator. Computer control electric fluid for the ER fluid H.inf. cotrol technique is adopted for the piezoactuator. Computer simulation is undertaken in order to demonstrate isolation efficiency of the engine mount over wide operating frequency range.

『황제내경(黃帝內經)』의 체질론(體質論)

최승훈,Choi, Seung-hoon 사상체질의학회 1998 사상체질의학회지 Vol.10 No.2

One's constitution is formed congenitally and is also acquired, and is relatively stable in its individually manifested function, structure and temperament. It has characteristics of universality, complexity, generality and continuity. It is also manifested in physiological responses and expresses pathologic tendencies including susceptibility. Attempts at understanding constitution has had a long history throughout the world. In Oriental Medicine, the constitution had been acknowledged from the "Huangdi Neijing", which has been a bible in Oriental Medicine for about two thousand years. In many aspects, the "Huangdi Neijing" provides the basis for both basic and practical fields. In order to derive the ideal structure from the "Huangdi Neijing" to Lee Je-ma's(Lee Jayma's) Sasang Constitutional ideas, which can strengthen the understanding of ideal core of Oriental Medicine's constitutional characteristics, the author launched his analysis of the constitutional understandings in the "Huangdi Neijing" as a first step and came to the following: 1. The constitutional understanding in the "Huangdi Neijing" was done both via the physiological responses to heat, pain and acupuncture treatment and the pathologic tendencies via body structure, strength, body heat, courage and obesity. 2. It was recognized that the constitution was formed congenitally and also acquired factors like living conditions including food customs, residents and geographical conditions were explained in detailed. 3. The constitutional typology was suggested both by the general and systematic criterion according to the Yin-yang and the Five phase theories and by single criterion such as obesity, courage and the response to acupuncture treatment. 4. As diagnosis is related to the constitution, courage was adopted for the disease caused by emotions, obesity was for its manifestations of qi and blood, the quantities of qi-blood and Yin-yang in the typology by the Yin-yang and Five phase theories were suggested. 5. In the case of obesity, Yin-yang and Five phase theory, treatment according to the constitutional ideas was mentioned, and their goals were concluded as "being the balancing between Yin and Yang" which means the Yin-yang theory is more practical than the Five phase theory in Oriental Constitutional Medical field. According to the above understandings, the author would like to suggest that the constitutional ideas in the "Huangdi Neijing" based on the Yin-yang theory blossomed via the practical spirit of Zhang Zhong-jing's "Shanghanlun" and at last from Lee Je-ma's(Lee Jayma's) Sasang Constitutional Medicine which realized "the balancing between Yin and yang" through the practical applications of herbal treatments.

One's constitution is formed congenitally and is also acquired, and is relatively stable in its individually manifested function, structure and temperament. It has characteristics of universality, complexity, generality and continuity. It is also manifested in physiological responses and expresses pathologic tendencies including susceptibility. Attempts at understanding constitution has had a long history throughout the world. In Traditional Chinese Medicine(TCM), the constitution had been acknowledged from the Huangdi Neijing, which has been a Bible in TCM for about two thousand years. In many aspects, the Huangdi Neijing provides the basis for both basic and practical fields. In order to derive the ideal structure from the Neijing to Lee Jay-ma's Four Type Constitutional Ideas, which can strengthen the understanding of the ideal core of TCM's constitutional characteristics, the author launched his analysis of the constitutional understandings in the Neijing as a first step and came to the following: 1. The constitutional understanding in the Neijing was done both via the physiological responses to heat, pain and acupuncture treatment and the pathologic tendencies via body structure strength, body heat, courage and obesity. 2. It was recognized that the constitution was formed congenitally and also acquired factors like living conditions including food customs and residents, geographical and social conditions were explained in detailed. 3. The constitutional typology was suggested both by the general and systematic criterion according to the Yin-yang and the Five Phase theories and by single criterion such as obesity, courage and the response to acupuncture treatment. 4. As diagnosis is to the constitution, courage was adopted for the disease caused by emotions, obesity was for its manifestations of chi and blood, the quantities of chi-blood and Yin-yang in the typology by the Yin-yang and the Five Phase theories were suggested. 5. In the cases of obesity, Yin-yang and Five Phase theory, treatment according to the constitutional ideas was mentioned, and their goals were concluded as "being the balancing between Yin and Yang" which means the Yin-yang theory is more practical than the Five Phase theory in the Traditional Chinese constitutional medical field. According to the above understandings, the author would like to suggest that the constitutional ideas in the Huangdi Neijing based on the Yin-yang theory blossomed via the practical spirit of Zhang Zhong-jing's《Shang Han-Lun》and at last from Lee Jay-ma's Four Type Constitutional Medicine which realized "the balancing between Yin and Yang" through the practical application of herbal treatments.

최승훈,방창현 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1

Conductive fibers have been attracted for various wearable systems that can applicable into smart clothes to detect various bio-signals, control temperature. To apply in such technologies, various methods using flexible hybrid materials have been utilized to fabricate conductive fibers. In this study, we developed a fiber-based sensor by using highly stretchable polymer fibers coated with the polymeric solution of nanomaterials(graphite and AgNWs). After optimization of the coating processes and the roughness of conductive fibers, two conductive fibers were twisted to monitor two different resistance-signals of the device originated from pressure and strain. In specific, the fiber sensor can monitor two different discernable signals, which are the resistancechanges in the singles of a conductive fiber and the contact resistance between two twisted fibers. By monitoring the particular waveforms of two different signals, we demonstrated that the device can detect various human-motions.
