과거와 다르게 최근의 병원들은 정보화로 인해서 상당한 양의 의료 데이터가 저장되어 있어서 이의 효과적인 이용에 관심을 가지고 있다. 그러나 기존 통합병원정보시스템(Integrated Hospital Information System)은 아직까지 일반관리와 원무관리 중심에서 벗어나지 못하고 있다. 품질 좋은 의료 서비스를 제공하기 위해서 환자 중심의 진료 및 진료지원, 임상연구 등을 종합적으로 지원하기 위한 데이터 웨어하우스의 필요성이 대두되기 시작했다 .이 글에서는 최근 임상 데이터 웨어하우스(Clinical Data Warehouse)에 초점을 둔 J병원 사례와 연구를 중심으로 기술한다.

김태훈,박세명,Kim Tae boon,Park Se myung 한국통신학회 2005 韓國通信學會論文誌 Vol.30 No.3B

본 연구에서는 PVM으로 구성된 클러스터의 공유를 기반으로 하는 단계화된 응용서비스 플랫폼을 기반으로 응용서비스를 구현함으로써 응용서비스 플랫폼의 유용성을 평가하였다. 응용서비스 플랫폼은 요청 처리에 필요한 전 과정을 요청처리 단계와 서비스제공 단계로 나누고, 서비스요청처리 단계를 위한 전위응용서버의 서비스관리자와 요청된 서비스의 분산을 담당하는 부하관리자, 그리고 후위서버에서의 서비스제공을 위한 작업관리자로 구성된다. 구현된 응용서비스 플랫폼은 필요한 처리자원을 동적으로 할당, 시스템을 재구성함으로써 기존의 단일서버 시스템에 비해 부하의 변화에 보다 능동적으로 대처할 수 있을 뿐 아니라, 기능의 변경없이 다양한 응용서비스의 구현을 지원함을 확인하였다. In this paper, through the implementation of the application service, we evaluated the feasibility and availability of the staged application service platform, which is based on the sharing of the PVM cluster. Application service platform provides three managers for dividing the request processing steps into two stages, such as a request processing stage and a service providing stage. Three managers and its relation to the divided stages are as follows, service manager and load manager to distribute the request in front-end server for a request processing stage, job manager in clustered(back-end) servers for a service providing stage. The experiment shows that the staged application service platform provides more stable and scalable characteristics and better performance improvement on the dynamic load changes than the single server system. And also it shows that real application service system can be implemented easily without modification of the proposed service platform.

The purpose of the study was to evaluate the surface and pore characteristics of the wool fabrics. The fabrics used for the study were 100fo wool fabrics woven with variation of weft density, weaving structure, and linear density. Their surface characteristics and mean pore diameter were measured. The results of the study were as follows: 1) Mean Pore diameter (MPD) of the samples increased with decreasing cover factor and weft density, and increasing surface roughness (SMD). It showed that MPD of 30's, single yarn, and plain fabrics were lam or 2) MPD of the samples increased with water vapor transmission rate and air permeability of the samples. 3) Coefficient of friction (MIU) of the samples decreased with increasing bulk dencity and weft density. It showed that MIU of 40's, folded yarn, and satin fabrics were lower In addition, MIU of the samples increased with keeping warmth ratio. 4) SMD of the samples decreased with increasing cover factor and weft density. It showed that SMD of 40's, folded yarn, and satin fabrics were lower. 5) As SMD of the samples increased, there were lots of larger pore in the structure, and thus water vapor transmission rate and air permeability of the samples increased.

Automated building construction systems are currently being employed as an effective alternative for the recent aging of the workforce and the lack of skilled labor. In order to apply such systems effectively in building construction process, the influence on overall construction process by the systems should be examined in the developing phase. Moreover, appropriate performance criteria for the systems should be determined based on the aspect of cost-effectiveness. Therefore, this study analyses performance criteria of an automated building construction system for steel framework by using a simulation technique, CYCLONE, and economic feasibility analysis in order to developing and employing the system efficiently. The study targets the steel girder installation process through a manless steel frame and joint method and bolting robot which is developed by the robot-based construction automation (RCA) group in Korea. The result shows that the manless steel frame and joint method leads substantial productivity improvement for the steel girder installation process by the reduction of loads for resources. In addition, considering productivity and costs of the system on overall process, the maximum permissible capital cost for the bolting robot increases dramatically when a cycle time of the robot ranges from 320 to 440 seconds. The results of this study will help develop cost-efficient system, and serve as a decision support model for appropriate resource inputs of the construction automation method.

연구목적: 기존의 인력에 의한 안전점검은 기술자의 안전이 우려되거나 접근이 어려워, 평가 및 데이터 확보에 한계가 있었고, 시설물의 노후화로 유지관리 대상이 증가함에 따라 더욱더 큰 문제가 되고 있다. 드론 기술이 발전하면서 외관조사에 이를 활용할 경우, 인력의 안전 보장, 시각적 데이터 확보, 신속한 점검 진단이 가능하며, 최근 드론에 의한 시설물 안전점검이 일부 도입되는 등 활용도가 높아지고 있다. 활용성을 보다 강화하기 위해서는 드론에 의한 시설물 외관조사의 대가기준이 필요하다고 판단되며, 본 논문에서는 댐을 대상으로 연구를 수행하였다. 연구방법:품셈 산출을 위해 기존 국내 안전점검 및 드론관련 대가기준을 조사하고, 드론을 활용한 안전점검 관련 절차를 비교분석하여 작업 절차 및 공종에 대하여 검토하였다. 또한 실제 댐에 대한 드론 촬영 및 입면정사영상 제작을 통해 실증 자료를 수집하였다. 연구결과: 드론을 활용한 시설물 안전점검을 위한 작업공종을 도출하였고, 작업공종에 따라 두 개의 댐을 대상으로 실증조사결과를 수집하였으며, 이를 바탕으로 댐기준시설물 규격 기준으로 품셈 안을 도출하였다. 시설물의 구조형식별, 규격별 조정비는 기존 지침을 적용하고, 기상기준점측량이 필요한 경우 건설공사표준품셈의 무인비행장치측량의 품을 적용하도록 하였다. 결론:드론을 활용한 외관조사 시 GSD를 세밀하게 할수록 촬영 사진 수가 크게 증가하여, 대가기준을 산출을 위한 보정으로 조정비 개념을 적용하였다. 더불어 안전거리 유지를 위해서는 최대 GSD가 한계를 나타내는 문제점도 고려해야 함을 알 수 있었다. Purpose: Safety inspections by existing personnel have been limited in evaluation and data securing due to concerns about the safety of technicians or difficulty in accessing them, and are becoming a bigger problem as the number of maintenance targets increases due to the aging of facilities. As drone technology develops, it is possible to ensure the safety of personnel, secure visual data, and diagnose quickly, and use it is increasing as safety inspection of facilities by drones was introduced recently. In order to further enhance utilization, it is considered necessary to base a consideration standard for facility appearance investigation by drones, and in this paper, research was conducted on dams. Method: To calculate the quality, existing domestic safety inspection and drone-related consideration standards were investigated, and procedures related to safety inspection using drones were compared and analyzed to review work procedures and construction types. In addition, empirical data were collected through drone photography and elevation image production for the actual dam. Result: Work types for safety inspection of facilities using drones were derived, and empirical survey results were collected for two dams according to work types. The existing guidelines were applied for the adjustment ratios for each structural type and standard of the facility, and if a meteorological reference point survey was necessary, the unmanned aerial vehicle survey of the construction work standard was applied. Conclusion: The finer the GSD in appearance investigation using drones, the greater the number of photographs taken, and the concept of adjustment cost was applied as a correction to calculate the consideration standard. In addition, it was found that the problem of maximum GSD indicating limitations should be considered in order to maintain the safe distance.

In construction material field, one of the ways to reduce $CO_2$ generation and environmental load is to decrease the use of cement materials. In this study, the cement material was replaced with a by-product from iron production which called BFS(blast furnace slag), when mortar specimens were made and it was expected to reduce environmental load significantly. Moreover, the added value can be created by using a by-product and cutting the production cost of concrete and mortar. 5 types of mixing water, BFS and the activator($Ca(OH)_2$) were used to make mortar specimens and the compressive strength test was carried out. All specimens were cured for 3, 7, 28days. As a result, all experimental groups had better strength than a control group. Above all, 2F-1 group had superior strength to the others. In order to raise confidence of the results, microstructure of mortar was observed and each specimen was analyzed. SEM images from all groups were compared with each other, and the area and the volume of micro-pore were measured through the porosimeter analysis. Through this research, it was tried to examine the potential for developing zero cement mortar and applying the micro-organism as a natural admixture material.

Equinus contracture of the gastrocnemius-soleus complex is associated with many foot and ankle diseases. We introduce a new simple technique that can be performed using a minimal incision with simple devices. Briefly, 0.5 cm sized medial and lateral longitudinal skin incisions are made at the level of the distal one third of the calf. The musculotendinous junction of the gastrocnemius is gently transected using an Arachnoid blade. The skin is, then, closed with non-absorbable sutures.
