  • Objectives The purpose of this study was to find out whether if there is correlation between the pattern differentiation questionnaire and edema index of body composition analysis. Methods The authors obtained results of pattern differentiation Questionnaires and body composition analysis tests from 195 female patients who visited the Oriental gynecology department in Kyung Hee university Oriental medicine hospital at Gang-dong. The authors conducted correlation analysis between indicators of Body composition analysis and each part of the pattern differentiation Questionnaire. Pearson correlation analysis was performed on SPSS version 13.0 for windows. Results There was negative correlation between the Phlegm Questionnaire and right arm ECF, left arm ECF, and left arm ECW of the Body composition index. There was no correlation between Yin-deficiency Questionnaire and Body composition index. There was no correlation between Heat pattern Questionnaire and Body composition index. There was positive correlation between the Cold pattern Questionnaire and right leg ECF, and right leg ECW of the body composition index. There was no correlation between degree of edema self-awareness and Body composition index. Conclusions The result showed that each Questionnaire score has different correlation or even no correlation with Body composition index and degree of edema self-awareness. Further studies are needed for a better understanding and interpretation of the relationship between edema index on Body composition analysis and Questionnaires.

  • 분리형 히트파이프식 열교환기는 증발기와 응축기를 폐열원과 열풍이 필요한 곳에 분리설치하고 증기 및 액체의 연락관으로 두 열교환기를 연결하여 하나의 폐루프를 구성하고 증발기와 응축기의 설치 높이차에 의해 작동이 이루어지는 것이다. 따라서 고온 및 저온유체의 병류 및 향류의 혼합배치가 용이하다는 장점이 있으나, 고온유체의 온도가 높을 경우에는 포화증기의 압력이 높아져 파이프가 견딜 수 있는 사용한계를 초과하게 될 수 있다. 또한 너무 낮으면 증기의 비체적증가와 함께 유속의 증가로 압력손실이 커져 설치높이차를 크게 하던지 증기연락관의 직경을 크게 하여야 하는 문제가 발생할 수 있다. 따라서 설계과정에서 고온유체 및 저온유체의 온도, 유량 등이 정하여진 상태에서 병류 및 향류로 배치하는 경우에 분리형 히트파이프식 열교환기를 Lmtd방법으로 설계하고, 고온 및 저온유체의 온도 및 유량이 실제 운전과정에서 변화가능한 범위에 대해 Ntu 방법으로 열교환량,포화증기압력 및 압력손실에 따른 증발기와 응축기의 설치높이차 등에 대한 가동특성을 고찰하였다.

  • The physical model considered here is a horizontal layer of fluid heated below and cold above with a conducting body placed at the center of the layer. The body has dimensionless thermal conductivities to the fluid of 0.1, 1 and 50. Two-dimensional solution for unsteady natural convection is obtained using an accurate and efficient Chebyshev spectral methodology for different Rayleigh numbers. Multi-domain technique is used to handle a square-shaped conducting body. The results for the case of a conducting body are also compared to those of adiabatic and neutral isothermal bodies. When the dimensionless thermal conductivity is 0.1, a pattern of fluid flow and isotherms and the corresponding time-averaged surface Nusselt number are almost the same as the case of an adiabatic body. When the dimensionless thermal conductivity is 50, a pattern of flow and isotherm and the corresponding surface and time-averaged Nusselt number are similar to those of neutral body. The results for the case of dimensionless thermal conductivity of unity are also compared to those of pure natural convection.

  • A semi-solid forming technology has some advantages compared with conventional forming processes such as die casting, squeeze casting and hot/cold forging. In this study, the numerical analysis of semi-solid filling has been studied with solid fraction fs = 30% of A356 aluminum alloys. The finite difference program of two-phase flow model of Navier Stokes' equation coupled with heat transfer and solidification has been developed to predict a filling pattern, liquid segregation and temperature distribution of semi-solid metals. It gives die filling patterns and final solidification area. It can predict mechanical properties of semi-solid forming processes.

  • This study aimed to develop functional underwear for elderly women in their sixties in terms of good fit, wear comfort and body temperature regulation. To satisfy elderly women's physical and metabolical needs, an automatic temperature control system via PCM treatment was applied. Underwear pattern was produced by producing body surface replica, which was derived from 3D body parametric model. Differential ratios of outline length and area between 3D surface and 2D plane were 1.4% and 0.5%, respectively. The reduction rate was determined as 10% through the expert's evaluation. PCM treated fabric showed higher Q-max, meaning that it can facilitate the thermal transition in hot situation. Moreover, it also showed higher insulation to preserve heat and keep warm microclimate in a cold weather. Heat distribution measurements on various body parts revealed that the temperature after PCM treatment was significantly higher. The clothing pressure after 10% pattern reduction showed higher before reduction, at the same time, even lower than the comfort clothing pressure range of $5{\sim}10gf/cm^2$, implying that experimental garment of this research is acceptable in terms of clothing pressure. Evaluation results on the comfort to move in various motions proved that adequate clothing pressure improved the wear comfort in various motions.

  • Objectives : This study was planned to help clinical treatment by examining the efficacy and frequency of use of medicines with removing nebula and improving vision action, centering on historical literature. Methods : Chinese literature centered on CNKI published after 2000 and ophthalmic books of the Beijing University of Chinese Medicine Library, regardless of the publication period. Domestic literature was searched using NDSL and OASIS, and literature published after 2000 was referenced. Results : According to traditional medical classics, as medicine with removing nebula and improving vision action, medicine with dispelling wind and clearing heat action accounted for the majority. However, it is desirable to use these medicine in the early stages of the disease. Conclusions : 1. Among the external contacts that induce corneal opacity, the wind-heat pattern was the most common. Among the visceral manifestation patterns that induce corneal opacity, liver or spleen was the most common. Cold-tempered medicine which is dispelling wind, clearing heat and bottling up the liver were most commonly used as therapeutic medicine. 2. As removing nebula and improving vision medicine, Cassiae Semen, Chrysanthmi Flos, Eriocauli Flos, and Buddlejae Flos have been widely used. 3. It has been investigated that removing nebula and improving vision medicine can be effectively used in the early stages of various diseases that cause corneal opacity.

  • The purpose of this study is to evaluate the clinical implication of Eight Principle Pattern Identification, EPPI in Sasang Typology. Although EPPI is considered as the most basic differential diagnosis in Oriental Medical Science, it has not been used actively enough in clinical practice owing to the presumption that EPPI is not sufficient for the analysis of complex clinical symptoms. In Zhang Jiebin's Jingyuequanshu, he separates Yin-Yang with Six-identification in EPPI when explaining them. This implies that it is difficult to talk about each of EPPI in same perspective. Thus, for the active clinical usage of EPPI it is necessary to study in hierarchical perspective. Lee Je-ma's Sasang typology could be a good example that uses the hierarchical perspective of EPPI. In the book Dongeuisoosebowon Lee Je-ma talks about differentiating Yin with Yang by constitution, Exterior with Interior and Cold with Heat accordingly, to apply in prescriptions. After differentiation, Yin and Yang are placed in higher level from the rest of EPPI, thus Yin and Yang can influence the rest of EPPI. This study showed the importance of EPPI in understanding the differential diagnosis system of Sasang typology in clinical perspectives.

  • Objectives: This study investigated the pattern identification (PI) and clinical index of Parkinson's disease (PD) for personalized diagnosis and treatment. Methods: This prospective observational multi-center study recruited 100 patients diagnosed with PD from two Korean medicine hospitals. To cluster new subtypes of PD, items on a PI questionnaire (heat and cold, deficiency and excess, visceral PI) were evaluated along with pulse and tongue analysis. Gait analysis was performed and blood and feces molecular signature changes were assessed to explore biomarkers for new subtypes. In addition, unified PD rating scale II and III scores and the European quality of life 5-dimension questionnaire were assessed. Results: The clinical index obtained in this study analyzed the frequency statistics and hierarchical clustering analysis to classify new subtypes based on PI. Moreover, the biomarkers and current status of herbal medicine treatment were analyzed using the new subtypes. The results provide comprehensive data to investigate new subtypes and subtype-based biomarkers for the personalized diagnosis and treatment of PD patients. Ethical approval was obtained from the medical ethics committees of the two Korean medicine hospitals. All amendments to the research protocol were submitted and approved. Conclusions: An objective and standardized diagnostic tool is needed for the personalized treatment of PD by traditional Korean medicine. Therefore, we developed a clinical index as the basis for the PI clinical evaluation of PD. Trial Registration: This trial is registered with the Clinical Research Information Service (CRIS) (KCT0008677)
