This clinical study is designed to find the characteristics of heat and cold according to Sasang Constitutions by using a statistical analysis. The study was conducted based on the questionnaire sheets and medical history (clinical data) of 1080 people registered at Sasang Constitution Information Bank (SCIB). The total number of people registered at SCIB was 1083; however, 3 Taeyangin's data were excluded in this study. The statistical analyses results on these data were: Most Taeumins have warm limbs, while Soeumins have cold ones. Taeumin, and Soyangin do not like hot weather, while Soyumin doesn't like coldness. As soeumins' body temperature is relatively lower than that of other constitutions, they tend to sleep tightly under blankets or comforters. Taeumin tend to drink more water because they sweat a lot; while Soeumin drink smaller amount of water because they sweat less. Both Taeumin, and Soyangin like cold food, but Soeumin liked hot food. Soeumin showed strong tendency for hot and cold food, while other constitutions displayed less inclination toward the certain temperature of food. Soeumin certainly had the remarkable response toward changes in heat and cold than other constitutions. The differences written above were proved to be meaningful enough by Chi-square test.

In this study, the performance characteristics of a welded plate heat exchanger was investigated experimentally. Performance tests were carried out according to the flow rate and inlet temperature of working fluid. As a result, the heat transfer capacity increased by 335.5 kW with an increasing the flow rate and temperature difference between hot and cold side. However, the overall heat transfer coefficient was increased with the increase of flow rate, and it was not effected significantly from inlet temperature difference between hot and cold working fluid. The pressure drop was increased by 55.78 kPa with an increasing the frow rate when the flow rate ratio between hot and cold side 1:1. However, the tendency of pressure drop was difference when flow rate ratio wasn't 1:1. In case that the flow rate ratio between hot and cold side was not 1:1, the pressure drop at the low flow rate side was higher than that when the flow rate ratio was 1:1, while pressure drop of the other side was decreased compared to that when the flow rate ratio was 1:1.

Korean, and identified the correlation of a constipation with life style, heat and cold symptoms, stress and life quality of them. We also identified the relationships of the constipation with stress and life quality. A Survey was conducted from April 23, 2010 to October 25, 2010 for 464 women and the collected data was analyzed with computer software of SPSS 19.0. In the result, the constipation group appealed for cold stomach(p=.008), dyspepsia(p=.006), and tiredness(p=.001). more often than the normal group. The constipation group experienced Dreaming(p=.003), light sleeping(p=.007) and a trouble in sleeping(p=.001) more often, which impaired the quality of sleeping. Compared to the normal group, the constipation group also showed a tendency of high stress and low life quality. Based on the results, all the factors of heat and cold symptom, life style, stress and life quality should be considered when developing medications for the prevention and improvement of constipation.

This paper aimed to provide the basic data on consumers' awareness, behavioral patterns, and purchase methods for pet fashion(dog clothes). Research was conducted in April 2023 among 183 college students from universities in the Gyeonggi-do region. The analysis results are presented below. When asked if they think clothes are a daily necessity for dogs, 74.3% recognized clothes as a daily necessity for dogs. The biggest purpose of clothing for dogs was 'physical health (prevention of cold/heat, etc.)' with 60.1%. 96.7% of the respondents were very positive about the development prospects for the pet fashion industry. 46.4% of the subjects were currently living with a dog, and 30.6% of the subjects have lived with a dog for 'less than 1-3 years'. 93.0% of college students who live with a dog own dog clothes. As for the dog's clothing style, T-shirt styles without a slit were the most common at 33.6%. 81.0% of companion dog owners were found to dress their dogs when going out, and the most common reason was 'physical health (prevention of cold/heat, etc.)' at 76.6%. When purchasing dog clothes, 72.2% of the subjects considered 'fitting with the dog/convenience', and 27.8% were 'focusing on the companion's taste'. As for how to purchase dog clothes, 39.2% chose 'store visits and online purchases', 34.2% chose 'store visits and purchases', and 26.6% chose 'online purchases'. As for the most considered part when purchasing clothes for dogs, 51.9% identified 'design' and 39.2% identified 'material'. 80.7% of respondents said they would increase the purchase of dog clothes in the future.

1. Objectives Due to a lack of detail guidelines for prescriptions to ordinary and pathological symptoms in ${\ulcorner}$DongyiSuseBowon${\lrcorner}$, doctors depend on their own decision when give a prescription. This study aimed to compare ordinary symptoms and pathological symptoms in regards to six prescriptions being applied to Soyangin to utilize them as guidelines in practices. 2. Methods Date were collected from September, 2003 to August, 2004 at the Sasang Constitutional clinic of Pohang Oriental Medicine Hospital. Patients were first asked to fill Out a questionnaire of symptoms that they had at the time of visiting. Data from 273 Soyangin patients whose chief complains got alleviated after taking the prescribed drug were analyzed to examine if there were differences in prescriptions according to ordinary or pathological symptoms complained. 3. Results and Conclusions 1. Hyungbangpaedog-san(Paedog) was given more to the patients having good digestive function than Hyungbangjihwang-tang(Hyungji) and Hyungbangdojeok-san (Dojeok) ; Dojeok was given for bloating symptom compared to Hyungbangsabaek-san(Sabaek). Yangkyuksanhwa-tang(Yangkyuk) and Dojeok were more like for patients with stomachache compared to Paedog. Doghwaljihwang-tang(Dogji) was prescribed to patients complaining frequent voiding compared to Sabaek while Sabaek was given for patients who prefer cold water and feel their body warm compared to other prescriptions. Yangkyuk and Dojeok were prescribed more likely to patients with feeling of suffocation than Sabaek. 2. In symptom comparisons between one prescription and the group of the rest of 5 prescriptions, Paedog was found to be prescribed when patients had good digestive function while Dojeok was given in symptoms cases of indigestion, bloating, constipation and dizziness. Sabaek was applied more for patients having tendency of preferring cold water and feeling of heat body as well as good digestive function. Hyungji was used for patients complaining a symptom of fatigue, in addition Yangkyuk was given to patients who were nervous, sensitive, or impatient when compared to Other prescriptions. Dogji was applied to frequent voiding, insomnia, tingling of extremities, backache or leg pain, or in case of tendency of catching a common cold.

Objective : We performed a clinical study to investigate pattern characteristics in persistent allergic rhinitis depending on Korean Medicine pattern questionnaire items as a pattern identification diagnostic tool. Method : 32 patients with persistent allergic rhinitis were asked to interview with doctor of Korean Medicine and perform the 4 pattern questionnaires(Cold-Heat Pattern, Phlegm Pattern, Yin Deficiency pattern, bloodstasis pattern). Then, we analyzed the response rate of each pattern questionnaires. Results : After diagnosis of Korean Medicine Doctor's pattern identification, 17 individual items have higher response rate, 7 of 17 items have a common tendency in allergic rhinitis. The other 8 of 10 items belong to Lung qi deficiency cold and Lung-spleen qi deficiency group, these have higher tendency of deficiency. In bloodstasis pattern questionnaires, we don't decide the tendency of patients with allergic rhinitis. Conclusion : The result may provide that we don't use Korean Medicine pattern questionnaires as a major tool in the pattern identification of allergic rhinitis. Continuous studies are needed to develop the standardized pattern identification diagnostic tool.

The effect of grain size on the tensile properties and fatigue behavior of austenitic high Mn steel has been investigated. The recrystallized austenite grain size of the cold rolled high Mn steel was increased as the annealing temperature increased from $600^{\circ}C$ to $1000^{\circ}C$. Larger austenite grain size decreased the yield strength and the tensile strength, and increased the uniform elongation due to transformation of some austenite into twins or E-martensite phase during deformation. Austenite grain refinement increased the tendency to form dislocation cells, instead. The specimen annealed at $1000^{\circ}C$ with large grain size showed lower fatigue crack propagation rate in low ${\Delta}K$ region due to rougher fracture surface caused by formation of deformation twins during fatigue at the crack tip region.

This study deals with residual stress prediction and hardness evaluation within cross ball grooved inner race fabricated by cold upsetting process consisted of upsetting and ejection steps. A raw workpiece material of AISI 5120H (SCr420H) is first spheroidized and annealed, then phosphophyllite coated to form solid lubricant layer on its outer surface. To investigate influences of the heat treatment, uni-axial compression tests and Vickers micro-hardness measurements are conducted. Three-dimensional elasto-plastic FE simulations on the upsetting step and the ejection one are performed to visualize the residual stress and the ductile (plastic deformation) damage. External feature of the fabricated inner race is fully captured by using an optical 3D scanner, and the micro-hardness is measured on internal cross-sections. Consequently, the dimensional compatibility between the simulated inner race and the fabricated one is ensured with a difference of under 0.243mm that satisfied permissible error range of ±0.50mm on the grooved surface, and the predicted residual stress is verified to have similar distribution tendency with the measured Vickers micro-hardness.
