Objective : The present study is aimed at providing basic data to help oriental medical hospitals devise efficient operational plans by analyzing the medical expenses of in-patients in an oriental medical hospital and the factors affecting such expenses. Methods : PASW 18.0 was used to analyze the medical insurance program data of 929 patients who were discharged from a university oriental medical hospital(with 105 sick-beds) during the period from January 1 to December 31, 2010 after treatment under the coverage of health insurance and medical aid. Results : 1) Of all the patients hospitalized, 63.3% were females, their mean age was 52.73 years old, and 87.7% was covered by the health insurance program. The biggest number or 31.2% of the patients were treated by the department of acupuncture, 31.5% suffered mainly from the diseases of musculoskeletal system and connective tissues, and the average length of stay at the hospital was 19.49 days. 2) There were statistically significant differences in total medical expenses by age, clinical department in charge, principal diagnosis, and number of days hospitalized while daily average medical expenses differed depending on age, type of medical security, clinical department, principal diagnosis, and number of days staying at the hospital. 3) Total medical expenses were found significantly influenced by age, type of medical security, clinical department, principal diagnosis, and number of days hospitalized(explanatory power : 95.9%), whereas type of medical security, clinical department and principal diagnosis turned out to exercise significant influence on the daily average medical expenses(explanatory power : 26.9%). Conclusion : Oriental medical hospitals are suggested to make efforts to ensure geographical and economical accessibility for their main clients, the elderly and middle-aged, as well as to improve satisfaction of the clients with the medical service provided. They are also encouraged to work out systems to specialize in treatment with a focus on chronic degenerative and adult diseases. In addition, they are expected to try to enhance people's awareness of oriental medicine in an attempt to diversify the brackets of clients and increase frequency of their utilization.

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.

Automatic large scale soil model generation is very critical stage for earthquake hazard simulation of urban areas. Manual model development may cause some data losses and may not be effective when there are too many data from different soil observations in a wide area. Geographic information systems (GIS) for storing and analyzing spatial data help scientists to generate better models automatically. Although the original soil observations were limited to soil profile data, the recent developments in mapping technology, interpolation methods, and remote sensing have provided advanced soil model developments. Together with advanced computational technology, it is possible to handle much larger volumes of data. The scientists may solve difficult problems of describing the spatial variation of soil. In this study, an algorithm is proposed for automatic three dimensional soil and velocity model development of southern part of the European side of Istanbul next to Sea of Marmara based on GIS data. In the proposed algorithm, firstly bedrock surface is generated from integration of geological and geophysical measurements. Then, layer surface contacts are integrated with data gathered in vertical borings, and interpolations are interpreted on sections between the borings automatically. Three dimensional underground geology model is prepared using boring data, geologic cross sections and formation base contours drawn in the light of these data. During the preparation of the model, classification studies are made based on formation models. Then, 3D velocity models are developed by using geophysical measurements such as refraction-microtremor, array microtremor and PS logging. The soil and velocity models are integrated and final soil model is obtained. All stages of this algorithm are carried out automatically in the selected urban area. The system directly reads the GIS soil data in the selected part of urban area and 3D soil model is automatically developed for large scale earthquake hazard simulation studies.

In spatial information processing, particularly in non-renewable resource exploration, the spatial data sets, including remote sensing, geophysical and geochemical data, have to be geocoded onto a reference map and integrated for the final analysis and interpretation. Application of a computer based GIS(Geographical Information System of Geological Information System) at some point of the spatial data integration/fusion processing is now a logical and essential step. It should, however, be pointed out that the basic concepts of the GIS based spatial data fusion were developed with insufficient mathematical understanding of spatial characteristics or quantitative modeling framwork of the data. Furthermore many remote sensing and geological data sets, available for many exploration projects, are spatially incomplete in coverage and interduce spatially uneven information distribution. In addition, spectral information of many spatial data sets is often imprecise due to digital rescaling. Direct applications of GIS systems to spatial data fusion can therefore result in seriously erroneous final results. To resolve this problem, some of the important mathematical information representation techniques are briefly reviewed and discussed in this paper with condideration of spatial and spectral characteristics of the common remote sensing and exploration data. They include the basic probabilistic approach, the evidential belief function approach (Dempster-Shafer method) and the fuzzy logic approach. Even though the basic concepts of these three approaches are different, proper application of the techniques and careful interpretation of the final results are expected to yield acceptable conclusions in cach case. Actual tests with real data (Moon, 1990a; An etal., 1991, 1992, 1993) have shown that implementation and application of the methods discussed in this paper consistently provide more accurate final results than most direct applications of GIS techniques.

Background: Ticks are one of the most common external parasites in dogs, and are associated with the transmission of a number of major zoonoses, which result in serious harm to human health and even death. Also, the increasing number of pet dogs and pet owners in China has caused concern regarding human tick-borne illnesses. Accordingly, studies are needed to gain a complete understanding of the bacterial composition and diversity of the ticks that parasitize dogs. Objectives: To date, there have been relatively few reports on the analysis of the bacterial community structure and diversity in ticks that parasitize dogs. The objective of this study was to investigate the microbial composition and diversity of parasitic ticks of dogs, and assessed the effect of tick sex and geographical region on the bacterial composition in two tick genera collected from dogs in China. Methods: A total of 178 whole ticks were subjected to a 16S ribosomal RNA (rRNA) next generation sequencing analysis. The Illumina MiSeq platform targeting the V3-V4 region of the 16S rRNA gene was used to characterize the bacterial communities of the collected ticks. Sequence analysis and taxonomic assignment were performed using QIIME 2 and the GreenGene database, respectively. After clustering the sequences into taxonomic units, the sequences were quality-filtered and rarefied. Results: After pooling 24 tick samples, we identified a total of 2,081 operational taxonomic units, which were assigned to 23 phyla and 328 genera, revealing a diverse bacterial community profile. The high, moderate and low prevalent taxa include 46, 101, and 182 genera, respectively. Among them, dominant taxa include environmental bacterial genera, such as Psychrobacter and Burkholderia. Additionally, some known tick-associated endosymbionts were also detected, including Coxiella, Rickettsia, and Ricketssiella. Also, the potentially pathogenic genera Staphylococcus and Pseudomonas were detected in the tick pools. Moreover, our preliminary study found that the differences in microbial communities are more dependent on the sampling location than tick sex in the tick specimens collected from dogs. Conclusions: The findings of this study support the need for future research on the microbial population present in ticks collected from dogs in China.

Background: Bovine papillomatosis is a type of proliferative tumor disease of skin and mucosae caused by bovine papillomavirus (BPV). As a transboundary and emerging disease in cattle, it poses a potential threat to the dairy industry. Objectives: The aim of this study is to detect and clarify the genetic diversity of BPV circulating in dairy cows in Xinjiang, China. Methods: 122 papilloma skin lesions from 8 intensive dairy farms located in different regions of Xinjiang, China were detected by polymerase chain reaction. The genetic evolution relationships of various types of BPVs were analyzed by examining this phylogenetic tree. Results: Ten genotypes of BPV (BPV1, BPV2, BPV3, BPV6, BPV7, BPV8, BPV10, BPV11, BPV13, and BPV14) were detected and identified in dairy cows. These were the first reported detections of BPV13 and BPV14 in Xinjiang, Mixed infections were detected, and there were geographical differences in the distribution of the BPV genotypes. Notably, the BPV infection rate among young cattle (< 1-year-old) developed from the same supply of frozen sperm was higher than that of the other young cows naturally raised under the same environmental conditions. Conclusions: Genotyping based on the L1 gene of BPV showed that BPVs circulating in Xinjiang China displayed substantial genetic diversity. This study provided valuable data at the molecular epidemiology level, which is conducive to developing deep insights into the genetic diversity and pathogenic characteristics of BPVs in dairy cows.

England is a significant base for international trade in Europe, and dispute resolution through arbitration is active. Therefore, due to the geographical relationship with the European continent, the settlement of trade transactions and disputes with European countries is one of the most essential tasks. In this regard, arbitration procedures in England have been actively used for a long time. In England, dispute resolution methods through arbitration have been developed centered on merchant groups such as guilds from the 16th century and have been actively used until today. However, the arbitration procedure also had the characteristics of the common law because there was no legislation related to arbitration. Therefore, arbitration based on common law was carried out until the first half of the 19th century. In the 'Arbitration Act 1889', two types of arbitration systems, 'common law arbitration' and 'statutory arbitration' coexisted. However, in the arbitration procedure, according to the newly enacted 'Arbitration Act 1889', the arbitration agreement was binding from the time the arbitration agreement was reached. There was a way to select an arbitrator even if it was not explicitly stipulated in the arbitration agreement, and the arbitration award was quickly enforced. Arbitration under contract was preferred over common law arbitration, where withdrawal and revocation of awards were possible. However, in response to these provisions, the England courts considered the arbitration system to deprive the courts of jurisdiction, while a strengthened judicial review of arbitration procedures was done. In particular, England unified the arbitration-related laws, which had been scattered for a long time, adopted the model law, and enacted the 'Arbitration Act 1996'. Under the recognition and enforcement of arbitral awards in 'Arbitration Act 1996', Section 66 deals with the recognition and enforcement of arbitral awards and foreign arbitral awards. Section 2 of the 'Arbitration Act 1950' is inherited and used as it is. Second, it deals with the execution of arbitral awards under the New York Convention: Article 100 (New York Convention), Section 101 (Approval and Enforcement of Awards), Section 102 (Evidence Presented by a Party Seeking Recognition and Enforcement), and Section 103 (Provides Matters Concerning Rejection Recognition and Enforcement).

Climate change is a very vital issue that can be no longer avoided. Korea has been a top-level country Iin dealing with carbon dioxide emissions since 1960. Many studies have been conducted to suppress or eliminate carbon dioxide emissions, which account for a large portion of greenhouse gases. Carbon Capture and Storage (CCS), the most practical method of them, plays a significant role. However, these methods have the disadvantage of the limits of geographical distribution and high possibility of re-emission into the atmosphere. Recently, ocean storage has been studied using Accelerated Weathering of Limestone (AWL), a technique for storing carbon dioxide in the ocean as an alternative to CCS, an underground storage. AWL is a method of converting carbon dioxide into concentrated water in the form of bicarbonate ion and discharging it to the ocean to dilute and store it. It does not cause re-emission to the atmosphere, and the discharged concentrated water increases the alkalinity of the ocean to prevent marine acidification. The objective of this study was to understand the behavior of DIC (Dissolved Inorganic Carbon) including carbon dioxide during the ocean discharge of bicarbonate ion concentrated water in AWL method. This study area was set near Ulleung-do where sufficient water depth and operational efficiency were secured. CORMIX model was used to calculate the material diffusion by submerged discharge using ship.

This study analyzed "Bukgwol Dohyeong (Drawing Plans for the Northern Section of Gyeongbokgung Palace)", which is an important source material for the restoration of the palace, by applying Paltaekron, the geomantic principle of bearings, in order to clarify the building layout principle of Gyeongbokgung Palace. Gyeongbokgung Palace shows the typical geographical conditions that meet the principle of Baesan Imsu (mountain in the back and water in the front) which takes Baegaksan Mountain as the main mountain and the overall layout of the buildings that meet the principle of 'Jeonchak Hugwan (narrow in the front and broad toward inside)' by using the natural topography that meets the principle of 'Jeonjeo Hugo (low in the front and higher toward back).' It is estimated that this layout and arrangement must have been led by geomantic principle of bearings. The analysis of the building layout plan of Gyeongbokgung Palace in the late Joseon Dynasty Period suggests the application of two methods: one is to divide central area from Gwanghwamun Gate to Geoncheongung Hall into eight layers and the other is to apply the bearings of the Eight Trigrams based on the building that becomes the center. As a result, the gate, main hall, and kitchen of all major buildings where the royal family lived are located in the auspicious bearings according to the geomantic principle of bearings while the spaces where people other than the royal family such as those who served the royal family and the officials operated in the palace or the hall that enshrines the ancestors such as Taewonjeong Hall are located in the ominous bearings. Therefore, the buildings of Gyeongbokgung Palace are arranged based on the geomantic principle of bearings.

Background: Panax ginseng Meyer has widely been used as a traditional herbal medicine because of its diverse health benefits. Amounts of ginseng compounds, mainly ginsenosides, vary according to seasons, varieties, geographical regions, and age of ginseng plants. However, no study has comprehensively determined perturbations of various metabolites in ginseng plants including roots and leaves as they grow. Methods: Nuclear magnetic resonance ($^1H$ NMR)-based metabolomics was applied to better understand the metabolic physiology of ginseng plants and their association with climate through global profiling of ginseng metabolites in roots and leaves during whole growing periods. Results: The results revealed that all metabolites including carbohydrates, amino acids, organic acids, and ginsenosides in ginseng roots and leaves were clearly dependent on growing seasons from March to October. In particular, ginsenosides, arginine, sterols, fatty acids, and uracil diphosphate glucose-sugars were markedly synthesized from March until May, together with accelerated sucrose catabolism, possibly associated with climatic changes such as sun exposure time and rainfall. Conclusion: This study highlights the intrinsic metabolic characteristics of ginseng plants and their associations with climate changes during their growth. It provides important information not only for better understanding of the metabolic phenotype of ginseng but also for quality improvement of ginseng through modification of cultivation.
