In order to investigate energy utilization of defatted rice bran and Comfrey (Symphytum Paregrinum) meal, hatched single comb White Leghorn male chicks were fed for 10 days on a commercial chick mash and for the subsequent 10 days on diets containing 17.0 % of cellulose, wheat bran, defatted rice bran and Comfrey meal, respectively. During experimental feeding period, daily body weight gain did not show significant differences among treatments though birds fed defatted rice bran diet consumed more diet than those fed Comfrey diet. And protein retention did not show significant differences while buds fed Comfrey diet retained lower lipids than those fed other diets. Ratio of metabolizable energy to gross energy(MEn/GE) of cellulose diet was lower than those of defatted rice bran and wheat bran diets. And the ratio of productive energy to MEn(PE/MEn) was not affected by the experimental diets though increasing tendency in wheat bran diet and decreasing tendency in defatted rice bran diet were found. MEn of wheat bran, defatted rice bran and Comfrey meal were 43.2, 34.2 and 9..0 % of GE, respectively, and contained 0.594, 0.018 and -0.023 ㎉ of PE per gram dry matter, respectively. Thus defatted rice bran and Comfrey meal were not utilized for productive energy. MEn intake and heat production per metabolic body size(㎏^(0.75)) was higher in birds fed defatted rice bran diet and lower in birds fed Comfrey diet compared with those of cellulose or wheat bran diets. The results indicated that unknown substances might be contained in defatted rice bran to increase heat production and in Comfrey meal to decrease feed intake.

본 논문에서는 기존에 제시된 MR-tree와 SQR-tree의 장점을 결합하여 대용량 공간 데이타를 보다 효율적으로 처리할 수 있는 하이브리드 인덱스 구조인 SQMR-tree(Spatial Quad MR-tree)를 제시한다. MR-tree는 R-tree에 R-tree 리프 노드를 직접 접근해주는 매핑 트리를 적용한 인덱스 구조이고, SQR-tree는 SQ-tree (Spatial Quad-tree)와 SQ-tree의 리프 노드마다 실제로 공간 객체를 저장하는 R-tree가 결합된 인덱스 구조이다. SQMR-tree는 SQR-tree를 기본 구조로 SQR-Tree의 R-tree 마다 매핑 트리가 적용된 형태를 가진다. 따라서, SQMR-tree는 SQR-tree와 같이 공간 객체가 여러 R-tree에 분산 저장되며 질의 영역에 해당하는 R-tree만 접근하면 되기 때문에 공간 질의 처리 비용을 줄일 수 있다. 또한, SQMR-tree는 MR-tree와 같이 매핑 트리를 통해 트리 검색 없이 R-tree 리프 노드의 빠른 접근이 가능하기 때문에 검색 성능을 향상시킬 수 있다. 마지막으로 실험을 통해 SQMR-tree의 우수성을 입증하였다. In this paper, we propose a hybrid index structure, called the SQMR-tree(Spatial Quad MR-tree) that can process spatial data efficiently by combining advantages of the MR-tree and the SQR-tree. The MR-tree is an extended R-tree using a mapping tree to access directly to leaf nodes of the R-tree and the SQR-tree is a combination of the SQ-tree(Spatial Quad-tree) which is an extended Quad-tree to process spatial objects with non-zero area and the R-tree which actually stores spatial objects and are associated with each leaf node of the SQ-tree. The SQMR-tree consists of the SQR-tree as the base structure and the mapping trees associated with each R-tree of the SQR-tree. Therefore, because spatial objects are distributedly inserted into several R-trees and only R-trees intersected with the query area are accessed to process spatial queries like the SQR-tree, the query processing cost of the SQMR-tree can be reduced. Moreover, the search performance of the SQMR-tree is improved by using the mapping trees to access directly to leaf nodes of the R-tree without tree traversal like the MR-tree. Finally, we proved superiority of the SQMR-tree through experiments.

The effects were examined from several conditions of $TiO_2$ photocatalysis reaction to phenols degradation by changing it's reacting conditions such as phenol concentration, pH, $TiO_2$ concentration, $H_2O_2$ concentration, flow rate, and intensity of ultraviolet rays. Phenol degradation was more efficient in low concentration of phenol, neutral pH. Phenol degradation appeared to increase as concentration of $TiO_2$ photocatalyst, that of $H_2O_2$ and intensity of ultraviolet rays increased. As $TiO_2$ dosage increased, initial rate constant k linearly increased. When $H_2O_2$ was injected more than optimum, phenol removal rate didn't increase in proportional to the change of $H_2O_2$ concentration as OH radicals was being consumed. When flow rate is less than $4.75m^3/m^2$ day, phenol removal efficiency appeared to decrease as ultraviolet rays transmission rate becomes low by $TiO_2$ suspension coated in photo reaction column. Meanwhile, initial rate constant according to light intensity change in less than $25mW/cm^2$ appeared to be in proportion to light intensity ($mW/cm^2$) Removal efficiency decreased about 12% after 180 minutes of reaction time while showed stable removal efficiency of 100% after 300 minutes when using regenerated $TiO_2$.

Cotton fabrics were treated with glyoxal for a nonformaldehyde durable-press finish by a pad-dry-cure method. $MgCl_{2}/citric$ acid mixture or $Al_{2}(SO_{4})_{3}$ were used as a catalyst. The effects of additives such as sodium tetraborate decahydrate (STB), sodium peroxoborate tetrahydrate (SPB), and sodium chlorite (SC) were examined. The additives improved the whiteness and strength retention of the treated fabrics. SPB was superior to STB for the whiteness and strength retention. SC was better than either SPB or STB in the wrinkle recovery angles (WRA) and strength retention while the whiteness was similar to that of SPB or STB. SC was more effective for improving the whiteness and strength retention when it was used together with sodium phosphate monobasic.

The fatigue analysis for cutout panel used for the weight reduction of aircraft has been conventionally performed through the open hole concept using the reference stress and stress concentration factor (Kt). However, in the actual structure cases, the goal of weight reduction might be less meaningful due to the conservative approach induced by the difficulties of extracting the confident reference stress from FE-Analysis in the complicated loading behavior. Therefore a new approach is proposed in order to secure the effectiveness of weight reduction and validate the confidence of the analysis results using the interaction of max-min principal stress at the critical location of open hole edge line.

유비쿼터스 컴퓨팅 환경이 발전함에 따라 GeoSensor와 같이 GPS 기능을 보유한 센서로부터 생성된 시공간 센서 데이터 활용이 증가하고 있으며, 시공간 센서 데이터를 사용해 사용자에게 다양한 서비스를 효율적으로 제공해주기 위한 시맨틱 센서 웹이 연구되고 있다. 특히, W3C에서는 OGC의 SWE(Sensor Web Enablement)와 같은 센서 관련 표준들을 활용하고, 센서 데이터를 온톨로지로 표현할 수 있는 SSNO(Semantic Sensor Network Ontology)를 개발하였다. 그러나 이러한 연구들은 비시공간 센서 데이터에 대한 질의 처리는 가능하지만 시간과 공간 정보를 포함하는 시공간 센서 데이터를 효율적으로 처리하기 어렵다는 문제점이 존재한다. 따라서, 본 논문에서는 OGC의 "OpenGIS Simple Feature Specification for SQL"에서 제시한 공간 데이터 타입과 공간 연산자를 확장하여 시공간 데이터 타입과 시공간 연산자를 지원하는 SSNO 기반의 시공간 시맨틱 센서 웹을 개발하였다. SSNO 기반의 시공간 시맨틱 센서 웹은 시공간 센서 데이터인 SensorML(Sensor Model Language)과 O&M(Observations and Measurements) 스키마를 분석하여 SSNO 문서로 변환 및 저장하고, 시공간 연산자와 시공간 추론 규칙을 적용하여 효율적인 질의 처리를 수행한다. 마지막으로, 이러한 SSNO 기반의 시공간 시맨틱 센서 웹을 가상 시나리오에 적용해 봄으로써 본 시스템의 효용성을 검증하였다. According to the recent development of the ubiquitous computing environment, the use of spatio-temporal data from sensors with GPS is increasing, and studies on the Semantic Sensor Web using spatio-temporal data for providing different kinds of services are being actively conducted. Especially, the W3C developed the SSNO(Semantic Sensor Network Ontology) which uses sensor-related standards such as the SWE(Sensor Web Enablement) of OGC and defines classes and properties for expressing sensor data. Since these studies are available for the query processing about non-spatio-temporal sensor data, it is hard to apply them to spatio-temporal sensor data processing which uses spatio-temporal data types and operators. Therefore, in this paper, we developed the SWE based on SSNO which supports the spatio-temporal sensor data types and operators expanding spatial data types and operators in "OpenGIS Simple Feature Specification for SQL" by OGC. The system receives SensorML(Sensor Model Language) and O&M (Observations and Measurements) Schema and converts the data into SSNO. It also performs the efficient query processing which supports spatio-temporal operators and reasoning rules. In addition, we have proved that this system can be utilized for the web service by applying it to a virtual scenario.

In order to investigate the biological utilization of defatted rice bran and Comfrey (Symphytum Peregrinum) meal protein, single comb White Leghorn male chicks were fed for the first 10 days on a commercial chick mash, For the subsequent 6 days on protein-free diet and for the next 6 days on the protein-free diet and diets substituted 17.0% of defatted rice bran and Comfrey meal with cellulose of the protein-free diet, respectively. Daily weight gain of the chicks fed protein-free diet was -5.2 g and those of the birds fed defataed rice bran and Comfrey meal diets were -1.3 and -2.3 g, respectively. Birds fed defatted rice bran consumed 76.6 g of diet which is greater than 47.2 g consumed by those fed Comfrey meal diet. Defatted rice bran and Comfrey protein were evaluated to be -0.46 and -1.13 for protein efficiency ratio, 1.42 and 1.36 for net protein ratio and 87.3 and 89.2 % for biological value. Protein digestibility and net protein utilization of defatted rice bran was higher compared with those of Comfrey .meal. The results indicated that Comfrey meal may contain an unknown substance which might have influenced feed intake and protein digestibility.

SDP Master 이중화를 지원하는 확장 SLDS 설계 및 구현

신인수,강홍구,이기영,한기준,Shin, In-Su,Kang, Hong-Koo,Lee, Ki-Young,Han, Ki-Joon 한국공간정보시스템학회 2008 한국공간정보시스템학회 논문지 Vol.10 No.3

최근 이동체의 위치 데이타를 활용한 위치 기반 서비스에 대한 관심이 높아지면서 보다 효율적인 이동체 위치 데이타 관리 시스템으로 클러스터 기반 분산 컴퓨팅 구조인 GALIS(Gracefully Aging Location Information System)가 제시되었다. 그러나, GALIS의 서브 시스템인 SLDS(Short-term Location Data Subsystem)에서 SDP Master는 다수의 SDP(Short-term Data Processor) 노드들이 처리한 질의 결과를 취합하여 Client로 보내는 구조이기 때문에 SDP Master에 장애가 발생하거나 부하가 집중될 경우에 서비스가 중지되거나 Client로의 응답 시간이 길어지는 문제가 있다. 따라서, 본 논문에서는 기존 SLDS에 이중화를 지원하기 위해 SDP Master를 추가하여 기존 SLDS의 안정성과 가용성을 높이고 이동체 위치 데이타의 질의 처리 성능을 향상시킨 확장 SLDS를 설계 및 구현하였다. 확장 SLDS에서는 이중화된 두 대의 SDP Master를 가동하여 한 SDP Master에 장애가 발생하더라도 다른 SDP Master가 서비스를 계속 제공함으로써 현재 위치 데이타의 실시간성과 시스템의 안정성을 보장한다. 또한, 확장 SLDS는 두 대의 SDP Master가 질의 처리를 분산하여 수행하기 때문에 Client로의 응답 시간을 줄일 수 있다. 마지막으로 확장 SLDS의 장애 테스트와 질의 처리 성능을 실험하였으며, 이러한 실험을 통해 확장 SLDS의 고신뢰성 및 고가용성을 검증하였다. Recently, with highly Interest In Location-Based Service(LBS) utilizing location data of moving objects, the GALIS(Gracefully Aging Location Information System) which is a cluster-based distributed computing architecture was proposed as a more efficient location management system of moving objects. In the SLDS(Short-term location Data Subsystem) which Is a subsystem of the GALIS, since the SDP(Short-term Data Processor) Master transmits current location data and queries to every SDP Worker, the SDP Master reassembles and sends query results produced by SDP Workers to the client. However, the services are suspended during the SDP Master under failure and the response time to the client is increased if the load is concentrated on the SDP Master. Therefore, in this paper, the extended SLDS was designed and implemented to solve these problems. Though one SDP Master is under failure, the other can provide the services continually, and so the extended SLDS can guarantee the high reliability of the SLDS. The extended SLDS also can reduce the response time to the client by enabling two SDP Masters to perform the distributed query processing. Finally, we proved high reliability and high availability of the extended SLDS by implementing the current location data storage, query processing, and failure takeover scenarios. We also verified that the extended SLDS is more efficient than the original SLDS through the query processing performance evaluation.

중소기업(中小企業)의 직장훈련(職場訓練)에 관한 연구(硏究)

On the job training is useful : a part of on the job training has increased the marginal productivity of future and rate of wage. Investment in a human capital depends on character of investment and market conditions. The innovation role of small and medium firms has recently received increasing attention in newly industrializing countries as they attempt to transform their industries from labor intensive to technology intensive. It also suggests some implications to the small and medium firms' strategies and public policies accelerating research and development. Lack of qualified scientists and engineers often inhibits the small and medium firms' ability to access and assimilate external technical information. Such technical personnel are particularly scarce in NICs. Therefore, how to employ these technical staff should be an important issue for small and medium firms seeking to acquire distinctive competences. Small and medium firms must invest further education and training to its labor.
