We intended to identify the health state of Oriental medical students and also to know how many things of health practice are in healthy group and non-healthy group classified by the THI average score, according to sasang constitution. We collected data with self-administered health questionnaires from 297 men and women, in 9 Korea oriental medical colleges. We diagnosed Sasang constitution using QSCC II and also estimated health degree using THI. Non-healthy group practiced much more health behaviors than healthy one, and there were significant difference in Taeeumin and Soeumin. Non-healthy group of Taeeumin, Soeumin and Soyangin all practiced much more constitutional health behaviors than healthy one, and Soeumin non-healthy and healthy one all practiced much less health behaviors than Taeeumin and Soyangin group. Non-healthy group practiced health behavior for health care and maintenance more than healthy-one, and health state was related with sasang constitution health care. Therefore, institutional and systematic environmental condition would be needed in practicing healthy behaviors for improving the quality of health, and especially developed health promotion programs according to Sasang constitution too.

Objectives This study is designed to examine the relationship between healthy state (完實無病) of Sasang constitution and pulse wave (脈波). Methods The subjects were 100 patients who were diagnosed with Sasang constitution and underwent pulse analyzer test. The status of urination, defecation, perspiration, and digestion was classified as good, intermediate, and poor. The power, depth, speed, and roughness of pulse waves (脈波) were analyzed. Results Patients with poor digestion had relatively powerless pulse wave (無力脈). Soeumin patients had a higher rate of poor digestion compared to other constitutions. Soyangin patients had a higher rate of poor perspiration compared to other constitutions. Soyangin with poor defecation had relatively choppy pulse wave (澁脈), and poor perspiraton had relatively slippery (滑脈). Soeumin patients with poor digestion had relatively powerless pulse wave (無力脈). Conclusions The pulse wave of poor healthy state (完實無病) is an expression of a pathological syndromes (病證) caused by lack of or damage to healthy energy (保命之主). It was concluded that the pulse analyzer can be used to evaluate healthy state (完實無病).

This study presents an energy analysis for large-strain cavity expansion problem based on the general strength criterion and energy theory. This study focuses on the energy dissipation problem during the cavity expansion process, dividing the soil mass around the cavity into an elastic region and a plastic region. Assuming compliance with the small deformation theory in the elastic region and the large deformation theory in the plastic region, combined with the general strength criterion of soil mass and energy theory, the energy dissipation solution for cavity expansion problem is derived. Firstly, from an energy perspective, the process of cavity expansion in soil mass is described as an energy conversion process. The energy dissipation mechanism is introduced into the traditional analysis of cavity expansion, and a general analytical solution for cavity expansion related to energy is derived. Subsequently, based on this general analytical solution of cavity expansion, the influence of different strength criterion, large-strain, expansion radius, cavity shape and characteristics of soil mass on the stress distribution, displacement field and energy evolution around the cavity is studied. Finally, the effectiveness and reliability of theoretical solution is verified by comparing the results of typical pressure-expansion curves with existing literature algorithms. The results indicate that different strength criterion have a relatively small impact on the displacement and strain field around the cavity, but a significant impact on the stress distribution and energy evolution around the cavity.

This quantitative study was investigated to examine the relationship between severity of state-trait anxiety and disordered eating patterns in some university students. This study used a cross-sectional study design. Total 347 students participated in this study (88 male and 259 female) among three universities. The assessment of eating disorder was conducted by Eating Attitudes Test (EAT-26), a score of >or=20 identified individuals likely to have an eating disorder, including anorexia nervosa and bulimia nervosa. Scores of healthy dietary behaviors were obtained by self-assessment instrument on healthy diet scale(20-item questionnaire), and severity of state-trait anxiety was calculated by state-trait anxiety inventory(Total 40- item questionnaire). In groups for each state anxiety and trait anxiety, there were divided between 50 percentile point of cumulatived scores of state anxiety and trait anxiety in all subjects. Linear regression analysis showed overall significant difference between dietary patterns(anorexia nervosa and healthy dietary behaviors) and severity of state-trait anxiety in all sex. Our results indicated that severity of state-trait anxiety may marked eating disorder symptomatology on dimensions of eating disorder prevention.

The purpose of this study is to develop the scale to measure family health and to analyze the data collected by the survey in order to develop the educational program for healthy family. The sample of this study is taken by 522 housewives who are living in Seoul and are over the age of 40. The data are analyzed according to frequency, percentages, t-test, Pearson's correlation analysis, and Multinomial logistic Regression analysis. The results of this study are as follows. First, the scale measuring family health is developed through interviews with the respondents, preliminary survey, and comments reviewed from specialists. The responses to the scale are significantly different depending on whether they answered their family is healthy or not. Second, minimum family performances for family health are related to the category of social involvement of the family. Third, the types of healthy family are grouped by the responses related to the current state and the status of family health. The number of the type of the worst state-the worst status of family health is the largest, followed by the number of the type of the best state-the best status of family health. Fourth, the important and significant variables that affected the types of family health are psychological variables rather than personal and household-related variables of the respondents.

Data modelling and interpretation for structural health monitoring (SHM) field data are critical for evaluating structural performance and quantifying the vulnerability of infrastructure systems. In order to improve the data modelling accuracy, and extend the application range from data regression analysis to out-of-sample forecasting analysis, an improved most likely heteroscedastic Gaussian process (iMLHGP) methodology is proposed in this study by the incorporation of the outof-sample forecasting algorithm. The proposed iMLHGP method overcomes this limitation of constant variance of Gaussian process (GP), and can be used for estimating non-stationary typhoon-induced response statistics with high volatility. The first attempt at performing data regression and forecasting analysis on structural responses using the proposed iMLHGP method has been presented by applying it to real-world filed SHM data from an instrumented cable-stay bridge during typhoon events. Uncertainty quantification and correlation analysis were also carried out to investigate the influence of typhoons on bridge strain data. Results show that the iMLHGP method has high accuracy in both regression and out-of-sample forecasting. The iMLHGP framework takes both data heteroscedasticity and accurate analytical processing of noise variance (replace with a point estimation on the most likely value) into account to avoid the intensive computational effort. According to uncertainty quantification and correlation analysis results, the uncertainties of strain measurements are affected by both traffic and wind speed. The overall change of bridge strain is affected by temperature, and the local fluctuation is greatly affected by wind speed in typhoon conditions.

With the development and utilization of urban underground space, the artificial ground freezing technology has been widely used in the construction of underground engineering in soft soil areas. The mechanical properties of soft clay changed greatly after freezing and thawing, which affected the seismic performance of underground structures. In this paper, a series of triaxial tests were carried out to study the dynamic response of the freezing-thawing clay under the seismic load considering different dynamic stress amplitudes and different confining pressures. The reduction factor of dynamic shear stress was determined to correct the amplitude of the seismic load. The deformation development mode, the stress-strain relationship and the energy dissipation behavior of the soft clay under the seismic load were analyzed. An empirical model for predicting accumulative plastic strain was proposed and validated considering the loading times, the confining pressures and the dynamic stress amplitudes. The relevant research results can provide a theoretical reference to the seismic design of underground structures in soft clay areas.

Background: Laminitis is a complex and debilitating disease of horses. Numerous predisposing factors contribute to laminitis development, however the exact pathogenesis remains undetermined. Serum T4, cortisol, and histamine are components of the innate stress response and could play a causative or contributory role. Stress hormone concentrations in laminitis are largely unknown. Objective: To evaluate parameters associated with stress response in horses with laminitis, and compare these to healthy horses and horses with gastrointestinal (GI) disease. Methods: Thirty-eight adult horses presenting for non-medical conditions, GI abnormalities, or clinical laminitis were prospectively enrolled. Horses were assigned to the appropriate disease group (healthy, GI disease, and laminitis) and had blood drawn on presentation to the hospital. Samples were analyzed for plasma endogenous adrenocorticotrophic hormone (eACTH), serum cortisol, serum thyroid hormone, and plasma histamine. Results: Stress hormone concentrations were significantly different between horses in the laminitis and GI disease groups. Plasma histamine levels were highest in horses with laminitis, compared with GI disease and controls. Both horses with laminitis and GI disease had increased plasma eACTH when compared to healthy horses. Horses with GI disease had higher serum cortisol concentrations than horses with laminitis or controls. Serum T4 was lower in horses with GI disease than in horses with laminitis and controls. Conclusions: Horses with laminitis had relative increases in both plasma histamine and eACTH concentrations. Serum T4 and cortisol concentrations of horses with laminitis did not differ significantly when compared to healthy horses. The role of stress hormones in equine disease warrants further investigation.
