Objectives : The theory of Latent Qi Wenbing and its counter-arguments were examined in terms of each argument's theoretical background and logicality. Methods :Arguments for and against the theory of Latent Qi Wenbing in medical texts were examined closely. Results & Conclusions : Each doctor's theory on Latent Qi Wenbing was examined in the following four aspects. First, to what kind of pathogenic qi was the patient exposed during Winter? Second, how did the pathogenic qi affect the body in the time of exposure? Third, how did the latent qi change over the Spring and Summer within the body? Fourth, what kind of weather generates the disease during Spring and Summer? Each argument had different opinions on each aspect. The main argument made against the theory of Latent Qi Wenbing is that it is impossible for the pathogenic qi that initially damaged the body to stay latent until it generates disease after some time. The theory of Latent Qi Wenbing could be assumed to have been created based on situations in which such explanation was adept. Factors that contribute to this theory could be explained through the condition of the healthy qi, state of cultivation during the past season, and constitutional factors.

The results of analyzing "Shanghanlun-Shanghan examples" of Song Dynasty Text and Liuwansu's writings in the pursuit of comprehending his views written in "Fire-Heat" & "Warm disease" -are as follow. 1.He introduced Exterior-Interior Shanghan and Latent in the Winter & recurrent in the Spring Shanghan concept in the Febrile disease pathology as the link and the bifurcation point. His perception on Febrile disease encompassed Shanghan and Febrile disease on the same plane but actually discriminated in the treatment and medication between the two actually. 2.He suggested Febrile disease pathology in the concept of Shanghan and Febrile disease, which is coherent in the formation of interior heat as the result of the invasion of the lung by warm pathogen described in Warm disease Wei, Qi, Ying and Xue Fen Syndrome differentiation. He expanded the concept of esoteric portal 玄府 of "Suwon Tiaojinglun", to that of the omni-present portal & way of Qi's all directions movement, which is in accordance of invasion of upper energizer 上焦 by warm or hot pathogen via mouth and nose as used in Warm disease three-energizer differentiation. 3.He recognized both exterior-interior febrile disease in the context of both exterior-interior contact cause disease. He prescribed pungent-cool exterior releasing medicinal similar to that of exterior-releasing treatment adopted in warm disease. As lily-talc powder百合散 introduced in "Golden chamber synopsis" dispells heat by promoting excretion of urine and defecation, it is regarded as the original formula of later ikwonsan yiyuansan 益元散.

Objectives : In present, various definitions of Zhongshu are being used interchangeably in Korea. The paper attempted to discover the disease of Zhongshu as studied by Lidongyuan, who was ahead of his time. Methods : A database of medical books has been studied to find Lidongyuan's writings on the disease of Zhongshu, and mentions about Li's works in past medical books. The paper contemplated the subject by defining the disease of Zhongshu and reviewing the disputes related to the subject. Results & Conclusions : Lidongyuan gave a detailed explanation on the fact that Zhangjiegu distinguished between Zhongshu and Zhongre, and this was influenced by Shangshu as mentioned in Taipinghuiminhejijufang. Therefore, it can be deduced that he was aware of the fact that summerheat-heat as latent summer heat syndrome is lurking inside the body, not being able to be released. According to the disease of Zhongshu by Lidongyuan, yin cold was receieved secondary after first receiving summerheat-heat. It is either summerheat damaged defensive qi, failure in storing the essence made defensive qi weak, or seasonal reasons have caused the defensive qi to be drained and leave the body exposed to damage by summerheat. This is because the fundamental main cause is the hitting of summerheat, since yin cold was received after the presence of summerheat-heat is made first. Many doctors in the following generation criticized that Lidongyuan's disease of Zhongshu cannot be named as a Zhongshu due to its similarity with Shanghan. However, they cannot be viewed as similar since it is a phenomenon where yin cold becomes congested while the body is weak and heat is generated in the body due to summerheat-heat. The doctors who said they were similar only focused on the external cause that was only the superficial issue. According to Lidongyuan's method, the right way to treat a Zhongshu disease is to use the method of tonifying the qi and eliminating the heat in conjunction with eliminating the internal dampness or treat the external syndrome, or to use a formula to tonify the qi and eliminate the fire heat before eliminating the internal dampness or treating the external syndrome.

Objective : I would like to determine the main factors, in other words, the subjects that are responsible for febrile paroxysm and how they interact at the time of onset, based on the "Discourse on Hak(瘧)" chapter of "Huangdi Neijing(黃帝內經)". Methods : First, the pathological mechanism of the paroxysm was examined as described in the text. Then the subjects in question were analyzed based on the contents of the text. Result : 1. Febrile paroxysm happens when the three factors coincide at the Fengfu(風府). The three elements are as follows: first defense qi(衛氣), second latent qi(伏邪) and third, external pathogen(新邪). 2. Fengfu(風府) is not a specific point, but a region which external pathogen(新邪) passes through during which the defense qi is deficient. Conclusion : Febrile paroxysm is not caused by either an internal pathogen or an external pathogen, but the interaction between the three elements of the internal and external pathogens and the condition of defense qi. Moreover, the site, Fengfu(風府), which the disease is manifested is not a specific point but a more general region where the pathogenic qi has invaded while defense qi has weakened.

Objective : Malaria(瘧疾) is a disease that's main symptom is paroxysm - a cyclical occurrence of sudden coldness followed by rigor and then fever. Since the introduction of the cause and mechanism of malaria(瘧疾) in the "Suwen(素問)", including Cold malaria(寒瘧), Warm malaria(溫瘧), Heat malaria(癉瘧) and Wind malaria(風瘧), there has been over 20 different kinds of malaria, each of which are introduced in multiple medical texts. Method : Through comparison between "Suwen(素問)" and other medical texts, the categories, causes and mechanisms of malaria can be analysed and organized to overview the whole feature of it. Results & Conclusion : External pathogens of malaria(瘧疾) are wind(風), cold(寒), summerheat (暑), dampness(濕), miasmic toxin(瘴), pestilence(疫), ghost(鬼). Internal pathogens of malaria(瘧疾) are dietary irregularities(飮食不節), overexertion and fatigue(勞倦), phlegm(痰), seven emotion(七情). Malaria can be categorized into four groups according to the pathological mechanism that leads to paroxysm. They are latency of disease(伏氣), external contraction(外感), internal damage(內傷), and combination of disease(合病). Malaria-Paroxysm(瘧疾發作) occurs when the three following factors collide strongly : defense qi(衛氣), latent qi(伏邪) and external pathogen(新邪). When collision of the three factors takes place in the interior(裏), the body experiences chills. When it takes place in the exterior(表), the body experiences fever. The cyclical occurrence of Malaria-Paroxysm follows the circulation of defense qi.

Farming activities are transforming from traditional skill-based agriculture into knowledge-based and technology-driven digital agriculture. The use of intelligent information and communication technology introduces the idea of smart farming that enables farmers to collect weather data, monitor crop growth remotely and detect crop diseases easily. The introduction of Plantix, a pest and disease management tool in the form of a mobile application has allowed farmers to identify pests and diseases of the crop using their mobile devices. Hence, this study collected the reviews of Plantix to explore the response of the users on the Google Play Store towards the application through Latent Dirichlet Allocation (LDA) topic modeling. Results indicate four latent topics in the reviews: two positive evaluations (compliments, appreciation) and two suggestions (plant options, recommendations). We found the users suggested the application to additional plant options and additional features that might help the farmers with their difficulties. In addition, the application is expected to benefit the farmer more by having an early alert of diseases to farmers and providing various substitutes and a list of components for the remedial measures.

Besides respiratory infection, COVID-19 has many neurological symptoms not only loss of smell and taste but also fatigue and brain fog. But it is a challenge to treat the neurological symptoms especially of anosmia and ageusia. In order to search for the therapeutic methods, the geographical diversity and pathological mechanisms of the COVID-19 and two symptoms were investigated from the latest clinical studies. Because the environmental conditions of the monsoon climate zone of East Asia and the Mediterranean and Oceanic climate zone of Italy, Britain, United States and tropical Brazil are different, each of diverse etiology and internal milieu should be considered differently in the treatment. SARS-CoV-2 exhibits the dampness-like characteristics and the olfactory and gustatory disorders are particularly more common than other flu or cold. and it tends to show features of damaging the lung qi of olfaction and heart-spleen qi of gustation. The mechanisms of olfactory and gustatory loss are various according to precursory, inflammatory, non-inflammatory and sequelar forms, so the therapeutic method should be designed for each period and pathology. If the process of inflammation arises from nasal and respiratory, olfactory epithelium to the central nervous structure by way of blood brain barrier, the treatment should be corresponded with the stage and depth of pathogen place. And if the olfactory loss is asymptomatic or in the initial stage, it can be applied intranasal topical scent therapy to relieve temporary locking of qi movement, but maybe also used in parallel together with herbs of relieving dampness toxin latent in the lung parenchyma.
