The purpose of this study is to identify the construction background of the permanent racecourse constructed by the Japanese around Seo-myeon Busan in 1930 and to analyze the historical meanings of city, architectural characteristics of racecourse facilities at the time of completion and the transition process by addition and improvement after the completion. The Busan Horse Racing Contest held at the land reclaimed from the sea of Busanjin in 1921 at the first time was settled at Seo-myeon opening permanent racecourse in 1930. The change of racecourse location into Seo-myeon instead of Yeonsan-ri as the original location reflects the historical meanings of city such as the accessibility of public transportation, the availability of securing a location for racecourse facilities, the extension of a city and the preparation of military base. The Seo-myeon racecourse completed on November 18, 1930 cost 15,550 won. Its stable was built in 1931, extensively repaired in 1932 and rebuilt in 1940. The betting shop which has been known as the building constructed during the Japanese Colonial Rule is considered to be the building constructed after August 1948.

This study examined the distribution of airborne metals concentrations and conducted a risk assessment in PM-10 in Gwangju from 2014 to 2022. There were a total of six points, and the concentration of heavy metals at each point was highest in the order of Pyeong-dong(1.5472 ㎍/㎥) > Nongseong-dong(1.2093 ㎍/㎥) > Geonguk-dong(1.0100 ㎍/㎥) > Duam-dong(0.9684 ㎍/㎥) > Seo-dong(0.9515 ㎍/㎥) > Nodae-dong(0.8321 ㎍/㎥). In recent years, the concentration of heavy metals in the atmosphere has generally risen, accompanied by an increase in heavy metals in the soil. The average seasonal concentrations were in the following order: spring(1.4448 ㎍/㎥) > winter(1.2939 ㎍/㎥) > fall(0.8303 ㎍/㎥) > summer (0.5928 ㎍/㎥). The atmospheric heavy metals most correlated with PM-10 were Ca(0.69), Fe(0.62), Al(0.62) and Mg(0.60). Within the acceptable risk level (1.0E-06) set in this study, heavy metals in the atmosphere were found to have the most excess cancer risk, and the integrated non-cancer risk was as low as 1 or less.

We intended to determine the usefulness of window operation for adult hydrocele repair. We reviewed medical records of 132 patients from January 1995 to June 1998 with primary hydrocele and evaluated complications and recurrence rates of eversion and/or excision, plication, and internal drainage technique. Recurrence rate was highest in internal drainage technique as 85.2%, and those of eversion and/or excision and plication technique were 1.3% and 4%, respectively. Complication rate was highest in eversion and/or excision technique, and lowest in internal drainage technique. Although complication rate was lowest in window operation, this operation could not be successful due to high recurrence, and we suggest that this operation should be abandoned for hydrocele repair.

Real-time spatial database application systems require that spatial data have to be updated within valid time and user queries should be processed in real-time. In these systems, it needs to be considered a processing about real-time spatial data and real-time spatial query they are not considered in a conventional spatial database application systems. Real-time spatial queries in real-time spatial database application systems are hard to be processed successfully, because spatial operation takes major time in total processing and its real-time spatial data are easy to miss their validity. Therefore, it is required a query processing technique that makes queries meet time constraints of real-time spatial query with keeping validity of real-time spatial data. real-time operation post-placing technique is proposed in order to meet time constraints of real-time data and queries in real-time spatial query processing with managing real-tome spatial data and considering that manages real-time spatial data used in real-time spatial query.

Threshing loss was increased due to dropping of the threshing efficiency when the 4 row head-feed combine harvested 5 row rice to improve harvesting performance of a combine. Reasonable design criteria were examined to determine the ranges of both of feed rate and the length of threshing drum for the 4 row head-feed combine being used as a 5-row combine. Harvesting performance increased as working width or working speed increased, it resulted in 15% increase when the working width increased from4 row to 5 row. Harvesting operations of the 4 row combine performed normally in the 4 row rice in threshing loss less than 1%, however, threshing loss increased to 2.25% in the 5 row due to poor threshing efficiency. The length of threshing drum was increased from 710 mm to 810 mm as well as the speed of crop feed chain was increased from 0.61 m/s to 0.75 m/s so as to improve the poor threshing efficiency resulted from the enlarged working width from the 4 row to the 5 row, which would decrease threshing loss less than 1%.

In u-GIS environments, GeoSensor generates sensor data streams including spatial information as well as various conventional sensor data from RFID, WSN, Web CAM, Digital Camera, CCTV, and Telematics units. This GeoSensor enables the revitalization of various ubiquitous USN technologies and services on geographic information. In order to service the u-GIS applications based on GeoSensors, it is indispensable to efficiently process sensor data streams from GeoSensors of a wide area. In this paper, we propose a GeoSensor data stream processing system for u-GIS computing over real-time stream data from GeoSensors with geographic information. The proposed system provides efficient gathering, storing, and continuous query processing of GeoSensor data stream, and also makes it possible to develop diverse u-GIS applications meet each user requirements effectively.

공간 데이터 웨어하우스에서 공간적 의사 결정을 위한 데이터 큐브 색인 기법

Most decision support functions of spatial data warehouse rely on OLAP operations upon a spatial cube. Meanwhile, higher performance is always guaranteed by indexing the cube, which stores huge amount of pre-aggregated information. Hierarchical Dwarf was proposed as a solution, which can be taken as an extension of the Dwarf, a compressed index for cube structures, However, it does not consider the spatial dimension and even aggregates incorrectly if there are redundant values at the lower levels. OLAP-favored Searching was proposed as a spatial hierarchy based OLAP operation, which employs the advantages of R-tree. Although is supports aggregating functions well against specified areas, it ignores the operations on the aspatial dimension. In this paper, an indexing approach, which aims at utilizing the concept hierarchy of the spatial cube for decision support, is proposed. The index consists of concept hierarchy trees of all dimensions, which are linked according to the tuples stored in the fact table. It saves storage cost by preventing identical trees from being created redundantly, Also, it reduces the OLAP operation cost by integrating the spatial and aspatial dimension in the virtual concept hierarchy.
