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.

This study aims to suggest new algorithm, named as Simoo, in order to improve spatial conflicts and vector displacement between linear features in generalization of the linear features. Main principles of Simoo algorithm is adoption of simplification and smoothening methods. Tolerance conditions used in Simoo are perpendicular length, external angle, and average vertex length. Main characteristics of Simoo are the application of scale, cartographic refinement, minimization of logical errors, and maintenance of geographical properties. The Simoo was applied through comparison to existing Douglas-Peucker algorithm. Resultantly, maintenance ratios of line such as coastal line and stream network were over 97% in both algorithms. The elimination ratio of vertex points may be more effective in Douglas-Peucker than in Simoo. Spatial conflicts between linear features may be more minimized in Simoo. The curvature and smoothening of lines become decreased in scale in application of Simoo. Finally, Simoo algorithm may be more effective than Douglas-Peucker for cartographic generalization.

This study tried to examine the possibility of rural tourism policy in Nam-Hae county and to provide a strategy for development of the local economy. It was carried out on a basis that the rural tourism businesses are operated by the local government(Nam-Hae county office). In doing so, this study investigated social, cultural and geographical characteristics and the regional tourism resources of Nam-Hae area. Based on the survey, it classified the types of rural tourism and suggested provisional tourist maps by the type. This study assumed that the local government has a full responsibility for the rural tourism businesses from the initial stage of setting up development plans to the operation of the businesses. Rural tourism theme courses of each small-position area provided tourists with tour courses and time schedules depended on geographical features of the areas. It produced a map that actually makes possible the theme rural tourism. The conclusion of this study is that the quality of living in Nam-Hae county would be improved with the rural tourism businesses which lead to increase in farm household income and to develop local settlement areas.

It is generally analyzed that the subject area of grassland development seen in the North Korea area following unification with the South Korea includes hillland, h o w upland, tideland, and other expected grassland development areas. Possibilities and prospects for grassland development become higher if such grassland is developed by methods of environmental affinity suitable to the geographical and environmental conditions of North korea. First, the grassland development has to be based on grass species which are both cold resistant and suitable to the climate and the soil conditions of North korea. In addition, research on adaptable species, mixture combination selections and grassland establishment methods should be performed along with the accumulation of domestic data. The kind of research can be conducted in such areas as Yenben in China(Yenben University), Taekwanryung and Taeback mountains, where geographical features are similar to those of North korea. This research is possible because research can easily be given access to these locations. Hence, it is desirable to prepare for the unification of the Korean peninsula by caning out basic and applied research, and by way of accumulating data in the relevant fields.

There are three natural conservation systems that UNESCO assigns: World Heritage, Biosphere Reserve and Geopark. Geopark is one of three preservation zones that UNESCO conducts. In this paper I will explain the meaning of a Geopark as well as suggest that one should be set up in Korea. Geotourism is one important aspect of Geopark. Geopark's main purpose is not only for sightseeing but also conservation and understanding the value of nature through geological and geographical features. I have analyzed the local guide's interpretations from a Hongdo Island cruise tour and suggested new way of interpretation for the tour with the concept of Korean Geotourism in mind.

To suggest the field maintenance plan considering the geographical characteristics of the region, we selected representative regions(plain regione and mountain region) and compared spatial distribution of cultivated land in Muan-gun and Hwasun-gun. Firstly, we examined the distribution characteristics of cultivated land according to the scope of the maintenance object with Fragstats. As a result of that, it was found that the cultivated area except rice paddy had the highest aggregation effect. And then, we developed type classification of maintenance considering geographic characteristics and cultivated crops information. As a result of classification, plain land type Muan region was mostly cultivated land suitable for integrated maintenance. On the other hand, Hwasun, a mountainous terrain, needs small-scale maintenance and road maintenance. Based on these results, it was found that more detailed planning is needed for the upland field infrastructure improvement considering the topographic characteristics.

This paper aims at an investigation of the features of bacterial communities in surface sediments of the South China Sea (SCS). In particular, biogeographical distribution patterns and the phylogenetic diversity of bacteria found in sediments collected from a coral reef platform, a continental slope, and a deep-sea basin were determined. Bacterial diversity was measured by an observation of 16S rRNA genes, and 18 phylogenetic groups were identified in the bacterial clone library. Planctomycetes, Deltaproteobacteria, candidate division OP11, and Alphaproteobacteria made up the majority of the bacteria in the samples, with their mean bacterial clones being 16%, 15%, 12%, and 9%, respectively. By comparison, the bacterial communities found in the SCS surface sediments were significantly different from other previously observed deep-sea bacterial communities. This research also emphasizes the fact that geographical factors have an impact on the biogeographical distribution patterns of bacterial communities. For instance, canonical correspondence analyses illustrated that the percentage of sand weight and water depth are important factors affecting the bacterial community composition. Therefore, this study highlights the importance of adequately determining the relationship between geographical factors and the distribution of bacteria in the world's seas and oceans.

Yangsan Fault stretches from Yonghae to the mouth of Naktong River in the south-eastern part of Korean Peninsula. The river terraces originated from alluvial fans are classified into the High, Middle, and Low Surfaces. The High Surfaces which were distributed in fragments are considered to be formed during the Mindel/Riss Interglacial period or the former periods. But the Middle and Low Surfaces which were distributed widely are considered to be formed during the Riss and Last Glacial period respecitively. The geomorphic and geologic features around Yangsan Fault suggest that the fault is right strike-slip fault, and some geomorphic evidences of active fault were found on Eonyang and Sinkwang Basin.

This article reviews Leptotrombidium deliense, including its discovery and nomenclature, morphological features and identification, life cycle, ecology, relationship with diseases, chromosomes and artificial cultivation. The first record of L. deliense was early in 1922 by Walch. Under the genus Leptotrombidium, there are many sibling species similar to L. deliense, which makes it difficult to differentiate L. deliense from another sibling chigger mites, for example, L. rubellum. The life cycle of the mite (L. deliense) includes 7 stages: egg, deutovum (or prelarva), larva, nymphochrysalis, nymph, imagochrysalis and adult. The mite has a wide geographical distribution with low host specificity, and it often appears in different regions and habitats and on many species of hosts. As a vector species of chigger mite, L. deliense is of great importance in transmitting scrub typhus (tsutsugamushi disease) in many parts of the world, especially in tropical regions of Southeast Asia. The seasonal fluctuation of the mite population varies in different geographical regions. The mite has been successfully cultured in the laboratory, facilitating research on its chromosomes, biochemistry and molecular biology.
