It is expected that EVP can be applied to the expanded area by researching EVP compensation scheme.

Since the collapse accident occurred frequently during the construction when the floor height is high and the connection is made more than two stories, the government recommends the installation of the system support instead of the pipe support in the case of the construction of the height over a certain height. However, the system has been repeatedly assembled in a narrow place, so that it is possible to work as a cause of the disease called musculoskeletal disease. Particularly, in temporary equipment lender and construction companies, it is necessary to repetitively work with assembling and tooling of each member when working on workers. Therefore, as the number of occupational diseases such as musculoskeletal diseases increases, the related research is underway. However, in the existing research, the research has been limited to the lighter weight of the scaffold and the formwork, and there is no research on the weight saving of the system supporting the form. Therefore, in this study, we perform performance test and structural analysis of the high strength lightweight system support, which is developed to minimize the worker's musculoskeletal diseases and workload, and compare with the performance of the current system support.

네트워크 보안 암호화 방식은 단대단 암호화 방식과 링크간 암호화 방식으로 구분된다. 네트워크 환경에서 보안 품질요구사항 이란 시스템이 제공해야 할 보안품질 속성의 수준이다. 품질속성은 관찰할 수 있고 측정할 수 있어야 하기 때문에 품질 요구사항도 가능하면 정확한 수치로 제시되어야 한다. 품질 요구사항이 정의되어야 구체적 품질 관리 목표가설정된다. 품질속성에서 기능적 요구사항은 암호화를 통해 얻을 수 있는 서비스 기능에 대한 요구조건이다. 비 기능적요구사항은 암호화를 통해 얻을 수 있는 서비스의 품질 요구조건이다. 본 연구에서 제안하는 암호화 품질 평가체계는기능적 요구사항과 비 기능적 요구사항 2개영역으로 도출한다. 평가지표의 동일 분류내 척도를 산출한 후 각 지표의 품질 측정값에 대한 연계지표를 작성한다. 품질평가 매트릭스는 품질측정 값에 대한 연계지표 분석용 2- factor 평가로서기능적 요구사항과 비기능적 요구사항 두 가지 기준으로 평균치를 산출 한다. 산출결과는 추세를 분석하여 종합 평가가가능하도록 한다. 이와같은 방식을 적용할 경우 네트워크 보안 암호화 품질평가의 기반을 구성할 수 있다.

The network security encryption type is divided into two, one is point-to-point, second method is link type. The level of security quality attributes are a system security quality requirements in a networked environment. Quality attributes can be observed and should be able to be measured. If the quality requirements can be presented as exact figures, quality requirements are defined specifically setting quality objectives. Functional requirements in the quality attribute is a requirement for a service function which can be obtained through the encryption. Non-functional requirements are requirements of the service quality that can be obtained through the encryption. Encryption quality evaluation system proposed in this study is to derive functional requirements and non-functional requirements 2 groups. Of the calculating measure of the evaluation index in the same category, the associated indication of the quality measure of each surface should be created. The quality matrix uses 2-factor analysis of the evaluation for the associated surface quality measurements. The quality requirements are calculated based on two different functional requirements and non-functional requirements. The results are calculated by analyzing the trend of the average value assessment. When used this way, it is possible to configure the network security encryption based on quality management.

The purpose of this study was to examine the educational effects of the early childhood science education lessons through field application by figuring out the influence of the early childhood science education lessons through field application on PCK(Pedagogical Content Knowledge) of pre-service early childhood teachers. To this end, targeting 51 pre-service early childhood teachers who are attending the Department of Early Childhood Education at U and D Universities in Chungbuk, the early childhood science education lessons were carried out the field application class in the experimental group(25 students) and the simulated class in the comparative group(26 students). The pre·post tests were used a test tool for ‘Early childhood teachers’ pedagogical content knowledge of science teaching’ by Kim Hyeon-jeong(1992). A difference between pre·post scores in two groups was statistically processed by executing independent sample t-test and ANCOVA. As a result of the research, first, the field application lesson was indicated to have a positive impact on enhancing PCK of pre-service early childhood teachers more than the simulated class. Second, the field application lesson appeared to have a positive influence on curriculum knowledge, learners’ knowledge, teaching-learning method knowledge, SMK(Subject Matter Knowledge), teachers’ professionalism knowledge, which are sub-spheres in pre-service early childhood teachers’ PCK. These results mean that there is a positive effect on the improvement of science content teaching knowledge (PCK) of pre-service early childhood teachers who applied field-applied early childhood science education classes. Therefore, it suggests that field application class is an effective method for teaching early childhood science for pre-service early childhood teacher.In addition, this study has educational significance in that it presented an example of class operation based on field connection, and it is expected that such class operation will be revitalized.s

This study evaluated combined cognitive-motor program based on Al-exander technique and Bartenieff fundamental method for mild cogni-tive impairment (MCI) patients. The purpose was to explore the field ap-plication of combined cognitive-motor learning program centering on proprioceptive neuromuscular facilitation, developing sensory-motor coordination and enhancing focused attention to one’s whole body. Two practice methods were applied to the 40 MCI elder. The combined cognitive-motor learning program (CM) was applied to the 20 MCI elder while 20 elder took traditional movement learning program (TM). Mini Mental States Examination-Korea (MMSE-K), Time Up & Go Test (TUG), Flexibility Test and Pegboard Test were measured and analyzed. The collected data were analyzed by paired t-test. The results were as fol-lows: Both groups showed similar learning effect in Flexibility Test and Pegboard Test. However, in MMSE-K and TUG, CM group showed sig-nificant learning effect than TM group. Our data suggested body awareness and body consciousness through Alexander technique and Bartenieff fundamental program facilitated patients’ kinaesthesia: sen-sory awareness and conscious control of the whole movement. From these results, we conclude that combined cognitive-motor learning program is valuable as alternative program for cognitive development as well as physical development of MCI elder.

This article reviews the recent activities of field testing and application of superconducting fault current limiters (SFCL) based on high-temperature superconductors (HTS). The review particularly focuses on the trends in the field tests in terms of the technical aspects and commercial activities of the SFCLs. Stimulated by the discovery of HTS, numerous research and development activities have been conducted worldwide for SFCLs operating from distribution voltages to transmission voltages. Different types of SFCLs have been developed and field-tested. Consequently, more than 20 field tests and applications have been performed on real grids worldwide while supplying electric power to the customers. These field tests have not only provided the track records of the operation experiences including the problems and maintenance during operation, but also proved their current limiting capabilities against real faults, rendering this new technology highly viable. Through these activities, the following trends in the status of field testing and application are observed. Resistive-type SFCLs with HTS-coated conductors were dominantly used in the most recent field tests. This implies that the resistive type is technically more mature than the other types. Bus-bar coupling and transformer feeders were the major application locations. It is of importance that most of the field applications were conducted as R&D projects. A relevant change from the R&D stage to the application stage is shown as recently deployed SFCLs are expected to be under long-term operation and commercial service. Here, we review the installation of these SFCLs by substation. This review also discusses the recent activities for their commercial applications.

However, proper acid treatment design and field operation are crucial due to the possibility of the formation incurring damage and for more effective stimulation of the reservoir. In this study, the overall process of matrix acidizing for oil wells in southern Alberta, Canada is summarized, together with descriptions of demonstration cases in preliminary research, acid treatment design, and field application process.

산불은 지표 식생의 소실과 토양 표층의 발수층 형성을 야기하여 강우 시 빗물의 침투를 저해 하고 지표유출을 가속화하는 요인으로 작용한다. 이러한 피해지역의 수문학적 변화는 토사 유출 량을 증대시켜 하류 생활권에 2차 피해를 유발할 수 있으며, 식생이 회복되는 과정에서도 사면 이 안정화되기 전까지는 산사태로 인한 토사재해 위험이 잔존한다. 본 연구에서는 산불피해지와 비피해지를 대상으로 파이프 하이드로폰 시스템을 적용하고, 장기간 축적한 소류사 데이터를 분 석하여 해당 기술의 현장 적용성을 검토하였다. 아울러 실측값과의 비교·분석으로 데이터의 신뢰 도를 검증하고, 이를 통해 산불 이후 산지 유역에서의 토사유출 특성 및 토사 이동 양상을 파악하고자 하였다.

Wildfires can result in the loss of vegetation cover and the formation of a water-repellent soil layer, thereby reducing infiltration capacity and increasing surface runoff during rainfall events. These hydrological changes can substantially increase sediment yield relative to the unburned conditions, posing a risk of secondary hazards to downstream communities. Moreover, the risk of sediment disasters triggered by landslides may persist during the vegetation recovery until slopes stabilization is fully achieved. This study evaluated the field applicability of a pipe hydrophone system in burned and unburned catchments by analyzing long-term accumulated bedload data. Additionally, data reliability was validated through comparative analysis with in-situ direct measurements. Based on these results, this study aimed to characterize post-fire sediment discharge and sediment transport patterns in a small mountainous catchment.

Purpose: The cavity exploration of the lower part of the road is carried out to prevent ground-sinking. However, the detected communities cannot be identified by the cavity location and history information, such as repackaging the pavement. Therefore, the field applicability of RFID systems was evaluated in this study to enable anyone to accurately identify information. Method: During temporary recovery, tag recognition distance and recognition rate were measured according to underground burial materials and telecommunication tubes using RFID systems with electronic tag chips attached to the bottom of the rubber cap. Result: The perceived distance and perceived rate of depth for each position of the electron tag did not significantly affect the depth up to 15cm, but it did have some effect if the depth was 20cm. In addition, water effects from nearby underground facilities and rainfall are relatively small, and the effects of wind will need to be considered during the weather conditions of the road. Conclusion: The RFID tags for field application of the pavement management system store various information such as location and size of cavity, identification date, cause of occurrence, and surrounding underground facilities to maximize cavity management effect with a system that can be computerized and mobile utilization.

The purpose of this study was to propose a plan for implementing qualification system for recognition of prior work experience in Korea. In order to achieve this, case studies of qualifications for RPL in advanced countries (France, Australia, UK, Scotland) were examined. Moreover, in order to ensure the validity of the scope and criteria of RPL proposed in the plan, expert council meeting was held during the developmental stage of the project. The main results of this study were as follows. Firstly, the range of recognition of field experience may vary depending on the category and grade of the qualification. When establishing the range of accreditation for the field experience, the suitability between the field experience obtained by the individual, and the qualification applied must be taken into consideration. Furthermore, the update of work experience, and the possibility of verification should also be taken into consideration. Secondly, the qualification criteria for the field experience can be set as the minimum duration of work experience required for the respective category and grade of each grade, the criteria for qualification, and the certification standard. In order to set the minimum years of required work experience according to each qualification item and grade, the minimum work experience needed to reach the needed proficiency should be taken into account before setting the examination criteria. Moreover, the exam questions and testing criteria could be designed based on work experience. Thirdly, to ensure the smooth operation of the system in its early stage of implementation, HRD Korea should take the role of supervising the approval of qualification items for recognition of prior work experience. However, in the long term, this role can be delegated to other evaluation committee or institutes including ISC and industries; while HRD Korea should manage the issuance and acquisition of certificates. Fourthly, the implementation of qualification system for recognition of prior work experience could be achieved in 6 steps: 1) Developing an evaluation plan, 2) Presentation and announcement of work experience evaluation, 3) Consulting and acceptance of applicants, 4) Assessment of work experience, 5) Review of assessment results, 6) Notification of results and certification issuance.

Wire rods having various sectional shape are generally used in various applications. In a 2-roll shape rolling process, step-by-step rolling operations are executed repeatedly and the rollers must be changed whenever the sectional shape of wire rod is changed. The frequent changes of the rollers and discontinuous repeated operations are cause various shortcomings such as increase of manufacturing cost and reduction in precision. We had developed a high precision automatic wire rod manufacturing system to reduce these shortcomings in the previous study. In this study, we evaluated the field application performance of the developed system in terms of straightness, thickness deviation, surface precision, tensile and hardness of the wire rod in order to verify the feasibility of the system.

Regarding bridge structure maintenance and inspection, this study was conducted to replace the current system, in which bridge diagnostics specialists ride on inspection vehicles to perform visual inspections, with a robotic system equipped with a small camera. The new system would greatly reduce the effort required, enhance the safety of inspectors and provide more accurate and efficient data that are objective and quantitative. For this purpose, a new robotic inspection system was developed for field test which was performed on Ahyun overpass bridge. Field test results are described to prove the on-site applicability.

The objective of the paper is to provide effective insulation curing method for cold weather concrete considering temperature condition in cold weather. Concretes were placed at the slab for deck plate and column executed at construction field for newly constructed department store building. Surface insulation curing materials studied by the authors were applied. According to results, under chilly climate condition, the combination of double layer bubble sheet and fabric sheet at the top surface of slab concrete made it possible to maintain its temperature above 15℃, which did not require any additional heating. At slight freezing condition in cold weather, the combination of double layer bubble sheet and fabric sheet at the top surface of slab concrete made it possible to maintain its temperature above 15℃ for over 2 days, which can prevent frost damage at early age. However, at severe freezing condition, as substantial measure against freezing is necessary, at top surface of concrete, the combination of double bubble sheet and fabric sheet and temporary tent around bottom section resulted in an effective curing, which maintained the concrete temperature above 5～10℃ for over 1.5 days and also, saved the cost for temporary works. This method may be the cost effective heat curing system. For column concrete, the wrapping of bubble board around the column can secure the stability against frost damage at early age by protecting the edge of column concrete vulnerable to cold weather.
