This study aimed to examine the possibility of data from pulse diagnosis device to be used for diagnosis of Sasang constitution. Systematic searches of 5 major Korean medical database were conducted for articles published up to May 2012. Searching key word was "Sasang" or "Constitution". Studies dealt with correlation between Sasang constitution and the pulse wave data from pulse diagnosis machine were included. Totally 2886 studies are searched and 3 studies are added from references of evaluated articles. Among them, 12 studies were met our inclusion criteria (2 Xishu Mac, 2 Self-made pulse diagnosis machine, 8 3D-Mac). Three of the eight 3D-Mac studies intended to develop a formula of constitutional differential diagnosis, 2 studies compared variables by Sasang constitution in healthy group and 3 studies compared variables by Sasang constitution in healthy group and special disease group. They all reported some significant variables, however results are not consistent between studies. The accuracy of the formula of constitutional differential diagnosis using 3D-Mac pulse diagnosis devices is 46.0% by now. Improvements in measuring pulse are required to achieve more accurate result and be used for diagnosis of Sasang constitution. Compensating B.M.I. among Sasang constitutional groups and separating constitutional pulse factors from acquired characteristics are also needed in further study.

This study is validity study of the questionnaire for doctors for Sasang constituion diagnosis. (an objects of this study : 314 patients) We analyzed the results of questionnaires about 314 patients who were diagnosed in Department of Sasang Constitutional Medicine from June to November, 2004. The questionnaire for doctors consists of objective valuation about the patients for Sasang constituion diagnosis. In the analysis about all variables, we obtain the diagnosis accuracy of 92%. In the analysis about body type variable, we obtain the diagnosis accuracy of 44-48%. In the analysis about external appearance, mental characteristics, physiology & pathologic symptoms variables, we obtain the diagnosis accuracy of 46-72%. After all, in order to increase of the diagnosis accuracy, we have to analysis total variables(body type, external appearance, mental characteristics, physiology & pathologic symptoms) for sasang constituion diagnosis. Hereafter, We need many data and standardization for sasang constituion diagnosis.

Hemorheology plays an important role in atherosclerosis. Hemorheologic properties of blood include whole blood viscosity, plasma viscosity, hemaocrit, RBC deformability and aggregation, and fibrinogen concentration in plasma. Blood flow is determine by three parameters (pressure, lumen diameter, and whole blood viscosity), whole blood viscosity is one of the key physiological variables. However, the significance of whole blood viscosity has not yet not been fully appreciated. Whole blood viscosity has a unique property, non-Newtonian shear-thinning characteristics, which is primarily due to the presence of RBCs. Hence, RBC deformability and aggregation directly affect the magnitude of blood viscosity, and any factors or diseases affecting RBC characteristics influence blood viscosity. Therefore, on can see that whole blood viscosity is the causal mechanism by which traditional risk factors such as hypertension, hyperlipidemia, smoking, exercise, obesity, age, and gender are related to atherogenesis. In this regard, we included whole blood viscosity in the three key determinants of injurious pulsatile flow that results in mechanical injury and protective adaptation in the arterial system. Because whole blood viscosity is a potential predictor of cardiovascular diseases, it should be measured in routine cardiovascular profiles. Incorporating whole blood viscosity measurements into a standard clinical protocol could improve our ability to identify patients at risk for cardiovascular disease and its complications.

Pulse diagnosis is one of the typical examination methods in traditional oriental medicine. However, it is necessary to obtain the objectivity for the standardization of this diagnosis. For this purpose, the pulse analyzer has been devised and studied, and the tonometric pulse analyzer displaying the pulse wave and its variables was developed recently. In this study, we investigated the effect of the sexuality of the individuals on the differences of the pulse wave as well as the correlation between the weight and the pulse wave to interrogate whether the pulse difference is not caused by the difference of sex but the size of individual.

Isoflavones are phytoestrogens and natural plant compounds which are similar to 17-${\beta}$-estradiol in chemical structure. It is known that they can act as estrogen agonists or antagonists, depending on endocrine estrogenic levels, but actions of isoflavones are rather complex due to large number of variables such as chemical structures and mechanisms. Some hypotheses on biological mechanisms have not satisfactorily been confirmed to date and human epidemiological and experimental studies have been relatively limited. Nevertheless, isoflavones and isoflavone rich foods have become a focus onf interest due to positive health benefits on many diseases, especially prevention of hormone-related cancers, cardiovascular disease, osteoporosis, and adverse postmenopausal symptoms, and improvement of physiological condition such as maintaining cognitive function. This review provides an overview of chemistry, analytical techniques (focused on human biospecimens), functions including biological mechanisms, and effects of isoflavones, on the basis of the available meta-analysis and review articles and some original articles, on health and cancer.

Standark polysomnograms, and questionnaires were measured using 4 subjects during simulated 150m heliox saturation dives. These measurements were performed on 4 pre-dive nights, 8 bottom nights, 6 decompression nights and post decompression nights. Sleep disturbances caused by frequent awakening were found throughout the dive period, but the disturbances were more intense on the second and fourth nights at the bottom and on the third and fourth nights of decompression. Stage 4 of sleep decreased every night at the bottom and from the first through third nights of decompression. The subjective self-evaluation of sleep was in agreement with the physiological variables. Complaints of subjective feeling of fatigue slightly increased throughout the dive period. It could be surmised that sleep disturbance or fatigue was not as significant under the 150m deep hyperbalic environment of He-O/ sub 2/ mixture, and therefore should be able to be coped with partially, through there moght be individual differences in adaptation.

This study reviewed the literature pertaining to the cause and effects of job stress. Many definitions of stress have been offered and the diversity of these definitions has been generated by medical scientists, psychologists, and behavioral scientists. Most approaches dealing with job stress have involved listing of various sources of job stress, moderators, and outcomes. This study is concerned with the selection of variables, the relationships between job stressors and outcomes, and the effects of moderators on these relationships investigated in job stress research. A review of job stress literature presents that various job stressors (e. g., task characteristics, role characteristics, organizational characteristics, career development, and relationships), moderators (e. g., locus of control, type A and B personality, social support, and demographics), and outcomes (e. g., perceived stress, job satisfaction, job commitment, organizational commitment, performance, turnover, and physiological symptoms) were used for a greater understanding of job stress.

In spite of the presumed importance of the strap muscles on laryngeal valving and speech production, there is little research concerning the physiological role and the functional differences among the strap muscles. Generally, the strap muscles have been shown to cause a decrease in the fundamental frequency(Fo) of phonation during contraction. In this study, an in vivo canine laryngeal model was used to show the effects of strap muscles on the laryngeal function by measuring the Fo, subglottal pressure, vocal intensity, vocal fold length, cricothyroid distance, and vertical laryngeal movement. Results demonstrated that the contraction of sternohyoid and sternothyroid muscles corresponded to a rise in subglottal pressure, shortened cricothyroid distance, lengthened vocal fold, and raised Fo and vocal intensity. The thyrohyoid muscle corresponded to lowered subglottal pressure, widened cricothyroid distance, shortened vocal fold, and lowered Fo and vocal intensity. It was postulated that the mechanism of altering Fa and other variables after stimulation of the strap muscles is due to the effects of laryngotracheal pulling, upward or downward, and laryngotracheal forward bending, by the external forces during strap muscle contraction.

In this study, when physician make a diagnosis of Sasang constitution of patients, anthropometric data are applied to seek the classification function into Sasang constitution. Data used in the analysis are the anthropometric data of 550 patients who had been treated in nine oriental medical hospital, and our data have no missing value in 12 anthropometric variables. In order to improve the accuracy of classification function into Sasang constitution, we consider one method of variable transformation of anthropometric data based on oriental medicine.
