An anomalous cold-weather period occurred during January 2011 in East Asia, and this study investigates the event by focusing on the blocking phenomena formed at Northeastern Asia. The area of cold weather is determined to represent the characteristic features of abnormal cold temperature. The 2010/11 winter is divided into three periods P1, P2 (cold period), and P3. For the cold area ($30-50^{\circ}N$, $115-135^{\circ}E$) the corresponding cold period P2 is determined to be 39 days from 23 December 2010 through 30 January 2011. During P1 and P3 temperature anomalies from the climatological mean are small with large standard deviation compared to those of P2, which has large negative anomaly and small standard deviation. The period P2 is dominated by blocking, which was determined by distributions of 500-hPa geopotential height and potential temperature on the 2 PVU surface. Correlation-coefficient analyses show that during P2 the temperature in the cold area is related with pressure of Northeastern Asia, while the temperature during P1 and P3 is related with pressure of Northwest of Korea. Also, during P1 and P3 the temperature pattern shows eastward propagation, but during P2, a stationary pattern. All the observations imply that, during the cold period P2, the temperature in the cold area is related with blocking in Northeastern Asia. During P1 and P3 temperature pattern is related with 500-hPa geopotential height in Siberia, and this relationship is also observed in the climatological mean state.

Human body fluid and humor include not only sweat, joint fluid but also every fluids, for example, blood, essence, kidney essence and marrow. Historically, in the oriental medicine, there are a lot of efforts in order to preserve fluid and humor. In "Treatise on Cold Damage and Miscellaneous Disease (傷寒雜病論)", when treating cold damage, preservation of fluid and humor is put first. I tried to find out the relation about fluid and humor and pain treatment in "Treatise on Cold Damage and Miscellaneous Disease". So, I investigated sentences related to pains in "Treatise on Cold Damage and Miscellaneous Disease" "greater yang disease part" and commentaries of several chinese medical doctors. And I divide pain treatments into four categories. (fluid and humor sufficiency-exterior pattern, fluid and humor sufficiency-interior pattern, fluid and humor deficiency-exterior pattern, fluid and humor deficiency-interior pattern) At first, when treating pains of cold damage, there are many considerations about deficiency and sufficiency of fluid and humor through pulse condition and symptoms. Second, in pain-cases of fluid and humor sufficiency, purge methods is chosen. And in pain-cases of fluid and humor deficiency, tonifying methods is chosen. Finally, one of the main objects of "Treatise on Cold Damage and Miscellaneous Disease" is preservation and supply of fluid and humor.

This study was performed to develop questionnaire of cold-heat pattern identification(PI) based on usual symptoms for general people, and we analyzed reliability of the questionnaire. We reviewed cold-heat PI questionnaire of advanced research and selected twenty-three items through three time experts meeting. Three hundred and fifty nine healthy subjects were joined in this study. As a results, Cronbach's α of cold-heat PI questionnaire was 0.79 and 0.83. According to the factor analysis about fifteen-chosen cold-heat PI questionnaires, each cold-heat consisted of two factors and each Convergence was 56.46% and 65.93%. Intra-class Correlation Coefficient was 0.67-0.83. Based on the median of samples of primary source, we classified subjects into four category as Cold, Heat, No Cold-Heat, and Cold-heat complex. We examined agreement of diagnosis and coefficient of kappa, and agreement rate of diagnosis was 64.2%, and coefficient of kappa was 0.51. Based on research result, we expect that validity study about questionnaire of cold-heat PI based on usual symptoms will be continued, and hope to be used as subsidiary diagnosis in clinical practice.

Objectives: Facial diagnosis is an important part of clinical diagnosis in traditional East Asian Medicine. In this paper, using a fully automated facial shape analysis system, we show that facial morphological features are associated with cold pattern. Methods: The facial morphological features calculated from 68 facial landmarks included the angles, areas, and distances between the landmark points of each part of the face. Cold pattern severity was determined using a questionnaire and the cold pattern scores (CPS) were used for analysis. The association between facial features and CPS was calculated using Pearson's correlation coefficient and partial correlation coefficients. Results: The upper chin width and the lower chin width were negatively associated with CPS. The distance from the center point to the middle jaw and the distance from the center point to the lower jaw were negatively associated with CPS. The angle of the face outline near the ear and the angle of the chin line were positively associated with CPS. The area of the upper part of the face and the area of the face except the sensory organs were negatively associated with CPS. The number of facial morphological features that exhibited a statistically significant correlation with CPS was 37 (unadjusted). Conclusions: In this study of a Korean population, subjects with a high CPS had a more pointed chin, longer face, more angular jaw, higher eyes, and more upward corners of the mouth, and their facial sensory organs were relatively widespread.

In Traditional Korean Medicine it is one of basic principle that personality reflects physical conditions. In both of personality and ordinary symptoms, there are some criteria used for diagnosis whether the patient is in cold or hot condition. We studied the relationship between the criteria of cold-hot shown in personality pattern and ordinary symptom pattern. And also analyzed the relativeness in four constitution type. 877 patients who had visited oriental medical hospital and had been confirmed their constitution by drug response were included in this study. Patients filled out the questionnaire composed of personality and ordinary symptom questions. We selected questions related to cold-hot patterns. Next we made personality cold-hot index(PCHI) and ordinary symptom cold-hot index(OSCHI). The two indices were compared and analyzed totally and from the viewpoint of 4 constitution types. The coefficient of correlation between two indices was not high. In Soemin the coefficient was 0.257, in three other constitution it was lower than 0.200 or negative. In Soemin both indices were lower (cold-biased), but in three other constitution no significant results were found. In Tae-emin OSCHI was higher (hot-biased) than PCHI, in Tae-yangin PCHI was higher than OSCHI significantly. Personality is not affected by cold-hot less than expected. The criteria used for diagnosis of cold-hot seems to be biased on Soemin's.

This study investigates synoptic characteristics of cold surges over South Korea during winter season (December-February). A total of 63 cold events are selected by quantile regression analysis using daily mean temperature observations from 11 KMA stations for 38 years (1979/80-2016/17). Large-scale pressure pattern during the cold surges is well characterized by high over Siberia and low over Aleutian regions, which elucidates cold advection over the Korean peninsula. However, the large-scale pattern cannot successfully explain the observed sudden decrease of temperature during the cold surges. Composite analyses reveal that a synoptic-scale cyclone developing over the northern Japan is a key feature that significantly contribute to the enhancement of cold advection by increasing pressure gradient over the Korean peninsula. Enhanced sensible and latent heat fluxes are observed over the southern ocean of Korea and Japan during the cold surges due to temperature and humidity differences between the near surface and the lower atmosphere over the ocean. The evaporated water vapor transported toward the center of the surface cyclone and condenses in the lower-to-middle troposphere. The released energy likely promotes the development of the surface cyclone by inducing positive PV near the surface of the heating region.

Objectives: The purpose of this study was to research the demographical and gynecologic characteristics, quality of life, and analyze the pattern identification in female patients with cold hypersensitivity of hands and feet. Methods: 112 participants were recruited from May 2018 to April 2019 from three korean medical hospitals. The data was composed of general characteristics, degree of coldness of hands and feet, gynecological questionnaire, score of WHOQOL-BREF and pattern identification. We divided data into 2 groups: The group of patients who meet the criteria for diagnosis of coldness on feet and the group of patients who meet the criteria for diagnosis of coldness on feet and hands. We tried to compare data by groups using Excel 2016 for windows and SPSS for windows (Ver. 23.0). Results: Throughout the study, we found differences between 2 groups in weight, body mass index (BMI), VAS score of cold hypersensitivity on feet, temperature of PC8, ST32, and pattern identification. Conclusions: After the study, we confirmed that even though both groups suffer from cold hypersensitivity of hands and feet, they show clinical differences in each group and differences in pattern identification.

We can understand "Shanghanlun(傷寒論)" and "Wenbingtiaobian(溫病條辨)" which are major books on externally contracted diseases well by making a comparative study of their similarities and differences. After studying etiological causes and characteristics of disease, disease pattern, syndrome differentiation, transmutation rules, following conclusions are derived. While cold is an etiological cause of Cold damage and harms Yang qi, heat is an etiological cause of Warm disease and harms Yin qi. Cold damage and Warm disease have something in common in the respect of damage to fluid and humor and Yang qi. Exuberant heat symptom of Yang brightness disease and lesser yin heat transformation pattern have similar damage to fluid and humor as Warm disease does. Warm disease can reach qi collapse syndrome through damage to Yang qi following fluid and humor damage. In the respect of water qi, as Cold damage makes water-dampness retain easily due to cold congealing, dampness-draining diuretic medicinal and warm yang medicinal are used together. As warm disease damages fluid and humor, yin-tonifying medicinal is used and dampness-draining diuretic medicinal can be used in the case of Warm disease with dampness. In the respect of disease pattern, cold syndromes arise mostly by Cold damage except heat syndrome of grater yang disease, chest bind syndrome, stuffiness syndrome, reverting yin disease and yang brightness disease. Warm disease is classified as pure heat syndrome and heat syndrome with bowel excess, damage to yin, qi collapse or damage to blood.

The association of cold-heat (CH) pattern and anthropometry/body composition has been suggested in that they are related to thermoregulation. We aimed to study the association of CH pattern and anthropometry/body composition. A total of 1479 individuals aged 50-80 years were included in the study, and their CH pattern were evaluated by a self-administered questionnaire. After adjustment for age and sex, the CH score were significantly correlated with weight, BMI (body mass index), body surface area, waist-hip ratio, fat free mass, body fat mass, body cell mass, intracellular water, extracellular water, and basal metabolic rate; however, the correlation coefficients were mostly low (0.15-0.24). The selected variables for predicting CH score were various according to the methods used for variable selection; however, the adjusted R-squared of the final models were all around 0.12. Thus the most parsimonious model could be the one that includes sex and BMI. In conclusion, various anthropometry and body composition indices were associated with CH pattern. Future studies are necessary to improve the performance of the prediction model.
