Objectives : The prevalence of allergic rhinitis (AR) is 10-40% worldwide and there are many demands for Traditionl Medicine (TM) treatment for AR. Pattern identification (PI) is essential process in diagnosis and treatment of TM, however, objective assessment measurement for PI of AR in TM is lacked. Methods : PI questionnaire for AR was developed in 2008 by specialists in the department of Otolaryngology of TM, based on systemic and nasal symptoms and signs. However, that questionnaire had many problems in application to clinical practice and has since been revised based on several studies and delphi method. Consequently, the PI questionnaire for AR version 3.0 has been developed. Results & Conclusions : This questionnaire classifies patients with AR as possessing lung-heat, lung-cold, or spleen qi deficiency based on nasal symptoms and general conditions of AR patients. This is first questionnaire for pattern identification of AR. We plan to conduct a validation and reliability study, and revise the questionnaire based on the results of this study.

The sea surface temperature (SST) and ocean heat content in the Korea Waters are gradually increased. Especially the increasing trend of annual mean SST in the Korea Water is higher about 2.6 times than the global mean during past 55 years (1968-2022). Before 2010s, the increasing trend of SST was led by winter season in the Korea Waters. However, this pattern was clearly changed after 2010s. The increasing trend of SST during summer is higher about 3.9 times than during winter after 2010s. We examine the long-term variations of several ocean and climate factors to understand the reasons for the long-term pattern changes of SST between summer and winter in recent. Tsushima warm current was significantly strengthened in summer compare to winter during past 33 years (1986-2018). The long-term patterns of Siberian High and East Asian Winter Monsoon were definitely changed before and after early- or mid-2000s. The intensities of those two climate factors was changed to the increasing trend or weakened decreasing trend from the distinctive decreasing trend. In addition, the extreme weather condition like the heatwave days and cold spell days in the Korea significantly increased since mid- or late-2000s. From these results, we can consider that the occurrences of frequent and intensified marine heatwaves during summer and marine cold spells during winter in the Korea Waters might be related with the long-term pattern change of SST, which should be caused by the long-term change of climate factors and advection heat, in a few decade.

Objectives: The aim of this observational study was to identify and analyze the patterns to compare the characteristics of asthma patients. Methods: The subjects were 40 asthma patients who had satisfied the inclusion and exclusion criteria. They were divided into deficiency syndrome and excess syndrome groups, and cold syndrome and heat syndrome groups. Their quality of life was measured by the quality of life questionnaire for adult Korean asthmatics (QLQAKA) and VAS. Heart rate variability (HRV) was measured, and the degree of obesity was evaluated by body mass index (BMI). Hematological, biochemical, and immunoglobulin (Ig) E laboratory tests were included. Results: Based on pattern identification, the 40 asthma patients could be divided into two categories of groups: 1) the deficiency syndrome (N=18) and the excess syndrome (N=22) groups: 2) the cold syndrome (N=35) and the heat syndrome (N=5) groups. The mean value of HF differed significantly between the deficiency and excess syndrome groups. The mean value of IgE in blood tests of asthmatics was greater than four times the reference value. For BMI, the subjects were classified into three groups: normal weight (N=12), overweight (N=12), and obese (N=16). Conclusions: Development of a more accurate asthma-specific pattern identification tool could play a crucial role in asthma control. In addition, good control of asthma can improve the quality of life. Obesity is one of the factors associated with asthma exacerbation.

The purpose of this paper is to derive the features of cold damage clinical medicine during the early days of the Chosun(朝鮮) period by analyzing discussions on cold damage published in the official medical book of the Chosun period, Compendium of Prescription from the Countryside(鄕藥集成方, CPC). Cold damage was one of the typical diseases in East Asia where there was constant seeking of the utilization of prescriptions, ways of preparations, and awareness regarding cold damage as shown in Zhang, Zhongjing(張仲景)'s Treatise on Cold Damage Disease(傷寒論, TCDD) below. Traditional Korean medicine which possessed the medical universality of East Asia also was no exception and through an analysis of the part on cold damage in CPC, it is expected that medical features of cold damage in Korea passed down from the Koryo(高麗) Dynasty to the early Chosun period will be revealed. For this, first there needs to be an organization of past discussions on cold damage surrounding the existence of infection and after checking the issues, exploring which of the writings related to TCDD and editions are being utilized through an analysis on citing literature of Cold Damage Disease Literature(傷寒門) and Heat Pathogen Disease Literature(熱病門) which have developed discussions on cold damage in CPC. In addition, by comparing Peaceful Holy Benevolent Prescription(太平聖惠方, PHBP) and Complete Record of Sacred Benevolence(聖濟總錄, CRSB), known to have greatly influenced CPC and Cold Damage Literature and Heat Pathogen Disease Literature, features of form and content used by CPC were analyzed. Features of form were examined through pattern of organization and number of citing literature were examined and for features of content, cold damage infection, classification, syndrome differentiation method, and utilization of materia medica among prescriptions were examined. Discussions on cold damage as being uninfectious as stated in Treatise on the Pathogenesis and Manifestations of All Diseases(諸病源候論) unlike pestilence, epidemic pathogen(時氣), warm pathogen disease(溫病), and heat pathogen disease were excluded in PHBP. PHBP opened the possibility of cold damage infection and later writings, CRSB and CPC also follow this. As a result of analyzing citing literature of the part on cold damage in CPC, it is uncertain which edition of TCDD is being utilized; however, the most distinctive feature was that Classified Emergency Materia Medica(證類本草) and not writings specializing in cold damage are in use. In general, although CPC in terms of form is similar to CRSB, content creation predominantly depended on PHBP. More specifically; first, in terms of the existence of cold damage infection, arguments of PHBP and CRSB are maintained. Second, in terms of cold damage classification, although CRSB is followed, heat pathogen disease is classified separately developing PHBP as is. Third, in terms of method, as Book of Keep Healthy(南陽活人書) and CRSB compiled in later times are cited, it is deemed that arguments were raised to a certain extent regarding six-meridian syndrome differentiation(六經辨證). Fourth, although the majority of utilized materia medica among cold damage prescriptions utilize Materia Medica from the Countryside(鄕藥本草) in CPC and materia medica from Korean Peninsula, this is due to the desire for the compilation performance of CPC to be propagated to ordinary citizens and not the ruling class. CPC as the official medical book compiled in the early days of the Chosun period was greatly influenced by the Song(宋) Dynasty's medical books, PHBP and CRSB shows that cold damage medicine in the early Chosun Period indeed possesses the medical universality of East Asia. Furthermore, the features of published medical theory and prescriptions reveal the existence of the cold damage medical tradition of the Chosun period serving as clues for cold damage research tradition among Korea's medical history.

Configuration of the inlet transition square duct (hereinafter referred to as "transition duct") for heat recovery steam generator (hereinafter referred to as "HRSG") in combined cycle power plant is limited by the construction type of HRSG and plant site condition. The main purpose of the present study is to analyze the effect of a variation in turbulent flow pattern by roof slop angle change of transition duct for horizontal HRSG, which is influencing heat flux in heat transfer structure to the finned tube bank. In this study, a computational fluid dynamics(CFD) is applied to predict turbulent flow pattern and comparisons are made to 1/12th scale cold model test data for verification. Re-normalization group theory (RNG) based k-$\epsilon$ turbulent model, which improves the accuracy for rapidly strained flow and swirling flow in comparison with standard k-$\epsilon$ model, is used for the results cited in this study. To reduce the amount of computer resources required for modeling the finned tube bank, a porous media model is used.

This experimental study measured and analyzed the heat transfer and pressure drop performance of brazed plate heat exchangers. Heat exchangers with different plate numbers of 10, 20, 30, and 40 were used for measurement, and their plate pattern was identical. The experiment was performed with distilled water, by changing the hot-side flow rate, with the cold-side flow rate fixed. The experimental results were compared with the calculated values by correlations based on gasketed plate heat exchangers, and showed that the heat transfer performance and pressure drop of brazed plated heat exchangers were higher than those of gasketed plate heat exchangers. From the variation of the friction factor, it could be inferred that in the flow channels of brazed plate heat exchangers, turbulent flow occurred at Reynolds numbers higher than 500. A new correlation to predict the Nusselt number was developed, and its absolute average deviation was 2.62%, compared with the values from the experimental data.

The concept of latent-gi(伏氣) was first mentioned in Yellow Emperor's Canon of Internal Medicine. For example, Elementary Questions states, "Damage by cold in winter necessarily engenders warm disease in the spring." Zhang Zhong-Jing of Han Dynasty in On Cold Damage and Miscellaneous Diseases mentions warm disease, stating, for example, "Greater yang disease with heat effusion and cough and without aversion to cold is warm disease. If sweating is applied, and there is generalized heat, this is wind warmth." However, the concept of warm disease was not central to his systematic presentation of externally contracted disease which placed the emphasis on wind and cold as the major causes of these diseases. Zhang Zhong-Jing's theories centuries after in the Sung Dynasty were to become the focus of the cold damage school, whereas the concept of warm disease was to become the focus of a rival school, the warm disease school. In the Sui-Tang Period, The Origin and Indications of Disease mentions warm diseases, their causes, patterns, and major principles of treatment. Successive generations of doctors wrote about warm disease, and in the Ming Dynasty writings on the subject become more prolific. This development is attributable on the one hand to the opening up of the south of China where febrile diseases tended to be of a different nature than in the north, and on the other to pestilences arising as a result of wars. In this period, Wu You-Xing in On Warm Epidemics explained in detail the laws governing the origin, development and pattern identification of warm epidemics. Notably, he posed the etiological notion of a contagious perverse gi.

The decreasing pattern of underground temperature measured at 'Gonjiam cold storage cavern' during 7 years which was the first commercial scale underground food storage cavern in Korea was analyzed. The variation of energy consumption was discussed by comparing the consumed energy at the initial operation stage with that at later stage, when the temperature distribution reached a stabilized condition. The point to be considered at the design stage was also discussed by comparing the required refrigerator capacity at the initial operation stage with that at later stage. The extra energy to freeze the groundwater contained in pore space was discussed by analyzing the changing pattern of the rock temperature. The variation of measured rock temperature was compared with the estimated temperature using a numerical code, FLAC. The accuracy of the numerical estimation was discussed by comparing the heat flux measured by the operation time of the refrigerator with that estimated numerically.

1. Objective: This literary review investigates Lee Jema's clinical experiences with Soyang-type patients and their influence on his conceptualization of the Soyang physiology and pathology. 2. Methods: 1) The case reports in "Soyang constitutional type: Spleen Cold-based Exterior-Cold disease" were compared before and after the Sinchuk revision to explore the temporal change in the Sasang medical concepts. 2) The texts in Donguisusebowon (Gabo edition) and Donguisusebowon (Sasangchobongwon) were analyzed to investigate the pathological concepts appearing before the completion of the Donguisusebowon (Gabo edition). 3) The texts in Donguisusebowon (Sinchuk edition) was analyzed to investigate the pathological concepts formed between the Gabo and Sinchuk editions of Donguisusebowon. 3. Results and Conclusions: 1) Gabo edition : The Gabo edition divided the External-origin Exterior disease into Cold-dominant (Heat-moderate) and Heat-dominant (Cold-moderate) patterns and differentiated the severity of Exterior-based Exterior disease and Interior-based Interior disease into mild, moderate, severe, and critical conditions. Cold-damage Delirium disease pattern was categorized as an Interior-based Interior disease, and the treatment protocol using Baekho-tang (Baihu-tang) was established. The stool condition and bowel movement reflecting the patient's defecation habits, the prime indicator of health in the Soyang constitutional type, were emphasized on their importance. 2) Sinchuk edition: The Delirium disease pattern was moved into the Exterior-cold disease, and the treatment protocol applying Jihwangbaekho-tang (Dihuangbaihu-tang) and Hyeongbangsabaek-san (Jingfangxiebai-san), with variational usage of Gypsum, was newly established. The Seong-Jeong and basal disease patterns were suggested as important factors in treating the patients. Also, it was proposed that the symptoms and signs reflecting the condition of the life-preserving energy be assessed to understand the patient's current condition. The importance of post-acute rehabilitation and aftercare as well as the most appropriate acute-stage treatment were emphasized.
