Objectives : As Daily Dose of Zizyphi Fructus was designated by the numbers in Treatise on Cold Damage Disease, estimation of Daily Dose was all different among researchers. The purpose of this study was to estimate exact Daily Dose of Zizyphi Fructus. Methods : We fixed the errors in various copy of Treatise on Cold Damage Disease and considered the meaning of the Bee Zizyphi Fructus(肥大棗) and general rules of Daily Dose in Treatise on Cold Damage Disease. So we reduced Daily Dose of Zizyphi Fructus, and compared this with the standard of Zizyphy Fructus in Pharmacopoeia of several Nation and Korean Forest Service. Results : Daily Dose of Zizyphi Fructus was generally 12 pieces; less was for prescriptions which scaled down the amount of ingredients prescribed in the originals; 15, 25, and 30 pieces were used when more was required. The medicinal part was the pulp of fructus, and the dosage of 12 pieces was respectively equivalent to 3 Ryang(兩), and 19.5 g. As defined in the Korean Pharmacopoeia Ninth Edition and standards of forest products by Korea Forest Service, Zizyphi Fructus was medium-sized, and weighs about 1.625 g if properly dehydrated. Conclusions : In short, the proper Daily Dose of Zizyphi Fructus in Treatise on Cold damage Disease was 12 pieces of Zizyphi Fructus and 19.5 g of its pulp, weighing three Ryang(兩). The pulp was estimated to be 1.625 g; it was medium-sized according to the present standard.

Since 2018, due to climate change, heat waves and cold waves have caused gradual damage to social infrastructure. Since the damage caused by cold weather has increased every year due to climate change in recent 4 years, the damage that was limited to a specific area is now appearing all over the country, and a lot of efforts are being concentrated from experts in various fields to minimize this. However, it is not easy to study real-time observation of sudden abnormal low temperature in existing studies to reflect local characteristics in discontinuously measured data. In this study, based on the weather-related data that affects the occurrence of cold-weather damage, we developed an algorithm pattern that can identify the time when abnormal cold temperatures occurred after searching for weather patterns at the time of cold-weather damage. The results of this study are expected to be of great help to the related field in that it is possible to confirm the time when the abnormal low temperature occurs due to the data generated in real time without relying on the past data.

Objectives Yusanghan(類傷寒) means disease which chills and fever manifest like Cold damage(傷寒) but not Cold damage. However, study on Yussanghan is insignificant. The purpose of this study is to examine the origin and development process of Yusanghan. Methods: 1. Terms and disease related with Yusanghan was collected from books covering Cold damage of all time and analyzed. 2. The transition history was researched by analyzing collected terms. 3. Total appearance frequency of all time by collected disease was researched. Results: Yusanghan was appeared in Hwalinseo(活人書), which Ju Geong(朱肱) of the Song Dynasty wrote, for the first time and the definition and type were established. For the types of those, there are four diseases such as Phlegm-Fluid Retention(痰飮), Food Accumulation(食積), Vexation of Deficiency Type(虛煩), Beriberi(脚氣). Since then, the theory about Yusanghan had developed and the number of types had also increased until the Myung Dynasty. Conclusions: In early days, External Contraction Diseases(外感病) was not included in Yusanghan, but since the late Myung Dynasty, there were a lot of doctors who included External Contraction Diseases in Yusanghan, not in Cold damage. There are Summerheat Stroke, Wind-Dampness(風濕), and Warm Disease(溫病) etc. for included External Contraction Diseases. Because of this, the number of types of Yusanhan had significantly increased.

Objects : The daily dose of Pinelliae Tuber in ≪Treatise on Cold Damage Diseases≫ is half seung in volume, two and half ryang in weight, and fifteen in total number. But the daily dose should be a whole number. So I found out the background of this setting and correct solution. Methods : I searched Classics of Traditional Medicine, found out the background of the daily dose setting, solution. Results : The daily dose of Pinelliae tuber in ≪Hangdi's Internal Classic Miraculous Pivot≫, ≪Bohenggyuljangbuyongyakbeobyo≫ is half seung. ≪Treatise on Cold Dameage Diseases≫ followed the same daily dose of that because it referred to these books. In ≪Synopsis of Prescription of the Golden Chamber≫, the daily dose of that is half seung, one or two seung. The half seung of the Pinelliae Tuber is thirty three mL, but the diameter is 1~1.5 cm that accurate measurement by volume is difficult. The daily dose by weight is correct considering the unity of marking of the daily dose, accuracy of measurement, the fact that Pinelliae Tuber is currently distributed by cutting. So, two ryang is correct which is thirteen gram. Conclusions : Considering the traditionality, the convenience of measurement, the daily dose of Pinelliae Tuber in the ≪Treatise on Cold Damage Diseases≫ is half seung, but considering the unity, accuracy, current state of distribution, it is correct that the daily dose of it is two ryang.

The complaint was filed for the cold water damage to rice in accordance with the installation of buried drain pipes in the mountainous areas of the valley. Field research was conducted in order to identify and analyze relevance of cold water damage to rice with underground drain pipe installation. In conclusion, water temperature was analyzed by 0.5 to $4.5^{\circ}C$ lower than before the installation of underground drain pipes, so the cold water damage to rice was likely to occur at the rice paddy field using cold water passing through the underground drain pipe. Therefore, the rice harvest was estimated to be impossible without appropriate measures of water temperature rise such as use of small unshaded warming basins, before water is applied to fields.

This study was conducted to compare differences in fruit quality by harvest time of 'Fuji' apple fruit that was frozen on tree by unusual low temperature in that air temperature was under $-3.5^{\circ}C$ for 7 hours. Fruits were harvested at 1 day before, and 2 days and 6 days after freezing damage, respectively. Harvest's soluble solid contents in all treatments was over $14^{\circ}Bx$. Firmness and titratable acidity of fruit harvested after freezing damage was lower than those of fruit harvested before freezing damage. During cold storage, ethylene production of fruit harvested after freezing damage was higher than that of fruit harvested before freezing damage. The reduction in the level of fruit quality during cold storage of fruit harvested after freezing damage was more serious than that of fruit harvested before freezing damage. The reduction of fruit quality during subsequent ambient temperature for 1 week after cold storage of fruit harvested after freezing damage was higher than that of fruit harvested before freezing damage. In comparison of treatments that were harvested at different times after freezing damage, ethylene production and reduction in the level of fruit quality until 8 weeks of cold storage of fruit harvested at 6 days after freezing damage was lower than that of fruit harvested at 2 days after freezing damage. However, this difference by harvest time after freezing damage disappeared after 8 weeks of cold storage. Incidence of flesh browning was not affected by freezing at air temperature under $-3.5^{\circ}C$ for 7 hours.

Objectives : This study aims to examine the multi-layered meanings of Li Dongyuan's concept of 'internal damage' through examining the origins of the 'internal damage' concept together with discussions derived from his 'Differentiation of Internal and External Damage'. Methods : Rather than Li's original works, those done by later doctors who were influenced by Li were thoroughly examined in this study to determine the relationships among internal and external damage, and external contraction. Results : Based on discussions related to the 'differentiation of internal and external damage' following Li, his concept of 'internal damage' could be understood as multi-layered, as it contains both spatial as well as pathogenic meaning. Therefore the meaning behind categorizations of internal and external damage, and internal damage and external contraction could be different. Li's 'internal damage' concept includes not only internal pathogen but elements of external contraction of wind and cold, which seems to have been integrated into the 'Cold Damage Theory' after Zhu Danxi, seemingly having changed the concept of cold damage. Therefore, discussions on the crossing between internal damage and external contraction have on one hand expanded the boundaries of each concept, while on the other hand, have caused confusion between the two at times. Conclusions : The concept of 'internal damage' has been widely accepted due to Li Dongyuan, on which related discussions have been centered. However, the concept was originally multi-layered, naturally leading to various discussions. Future studies should focus on the relationship of 'internal damage' with 'external damage' or 'external contraction', beyond the theories of Li.
