Buckling restrained braces (BRBs) were developed as an enhanced alternative to conventional braces by restraining their global buckling, thus allowing development of a stable quasi-symmetric hysteretic response. A wider adoption of buckling restrained braced frames is precluded due to proprietary character of most BRBs and the code requirement for experimental qualification. To overcome these problems, BRBs with capacities corresponding to typical steel multi-storey buildings in Romania were developed and experimentally tested in view of prequalification. The first part of this paper presents the results of the experimental program which included sub-assemblage tests on ten full-scale BRBs and uniaxial tests on components materials (steel and concrete). Two different solutions of the core were investigated: milled from a plate and fabricated from a square steel profile. The strength of the buckling restraining mechanism was also investigated. The influence of gravity loading on the unsymmetrical deformations in the two plastic segments of the core was assessed, and the response of the bolted connections was evaluated. The cyclic response of BRBs was evaluated with respect to a set of performance parameters, and recommendations for design were given.

One of the salient nuclear fuel performance parameters for new fuel types under development is changes in fuel thickness. To test the new commercially fabricated U-10Mo monolithic plate-type fuel, an irradiation experiment was designed that consisted of multiple mini-plate capsules distributed within the Advanced Test Reactor (ATR) core, the mini-plate 1 (MP-1) experiment. Each capsule contains eight mini-plates that were either fueled or "dummy" plates. Fuel thickness changes within a fuel assembly can be characterized by measuring the gaps between the plates ultrasonically. The channel gap probe (CGP) system is designed to measure the gaps between the plates and will provide information that supports qualification of U-10Mo monolithic fuel. This study will discuss the design and the results from the use of a custom-designed CGP system for characterizing the gaps between mini-plates within the MP-1 capsules. To ensure accurate and repeatable data, acceptance and calibration procedures have been developed. Unfortunately, there is no "gold" standard measurement to compare to CGP measurements. An effort was made to use plate thickness obtained from post-irradiation measurements to derive channel gap estimates for comparison with the CGP characterization.

In the construction and development of modern industrial production technology, the traditional technology management mode is faced with many problems such as low qualification rates and high application costs. In the research, an improved workpiece defect detection method based on deep learning is proposed, which can control the application cost and improve the detection efficiency of irregular defects. Based on the research of the current situation of deep learning applications, this paper uses the improved Faster R-CNN network structure model as the core detection algorithm to automatically locate and classify the defect areas of the workpiece. Firstly, the robustness of the model was improved by appropriately changing the depth and the number of channels of the backbone network, and the hyperparameters of the improved model were adjusted. Then the deformable convolution is added to improve the detection ability of irregular defects. The final experimental results show that this method's average detection accuracy (mAP) is 4.5% higher than that of other methods. The model with anchor size and aspect ratio (65,129,257,519) and (0.2,0.5,1,1) has the highest defect recognition rate, and the detection accuracy reaches 93.88%.

The purpose of this study was to clarify the distinct working areas of Certified Housing Environment Professional(CHEP) through the job analysis, to prepare the basic documentation required for a national official approval, and to provide the information of the curriculum organization for collegiate education on housing environment-related majors. Two previous reports, the qualifying system and performed in 2005 and 2009 by the qualification management committee under the Korean Housing Association, were foundation of this study. Two advisory council meetings were held, which are composed of 5 housing professionals and 11 professors working in housing environment-related departments. The results of the study were summarized as follows. The main jobs of CHEP were classified into six categories; the analysis, planning, service, residents' evaluation, social evaluation, and physical evaluation of the housing environment. CHEP can participate in the planning stage of architectural or interior design through the investigation of residents' perception and behaviors, and the analysis of socio-economic and life style trends. They also can play an important role in living supporting services of housing management area through the community program development, management and evaluation, which may bring about community vitalizations and social integrations. This study might need to finalize based on the affluent input of colleague.

With the advances in recent nanotechnology, mass transport phenomena have been receiving large attention both in academic researches and industrial applications. Nonetheless, it is not clearly determined which parameters are dominant at nanoscale mass transport. Especially, membrane is a kind of technology that use a selective separation to secure fresh water. The development of great separation membrane and membrane-based separation system is an important way to solve existing water resource problems. In this study, glass fiber-based membranes which are treated by graphene oxide (GO), poly-styrene sulfonate (GOP) and sodium dodecyl sulfate (GPS) were fabricated. Mass transport parameters were investigated in terms of material-specific and structure-specific dominance. The 3D structural information of GO, GOP, and GPS was obtained by using synchrotron X-ray nano tomography. In addition, electrostatic characteristic and water absorption rate of the membranes were investigated. As a result, we calculated internal structural information using Tomadakis-Sotrichos model, and we found that manipulation of surface characteristics can improve spacer arm effect, which means enhancement of water permeability by control length of ligand and surface charge functionality of the membrane.

In Korea, primary school (also junior high school) is compulsory and free since 2004. But it looks high school is also compulsory, as over 80% of adults has a high school diploma currently. For 20 years improving high school education is only education-oriented, rather than occupation-oriented. And, the mismatch between the occupational requirement and the lesson from school is getting larger. To resolve this issue, the Korean government builds and utilizes National Competency Standards(NCS) to realize a competence-oriented society. With NCS, the government enables to run of a work-study program and tries to suggest the fundamental solution to improve occupational ability and the unemployment of young people. However, the prejudice against the education level and occupation is still engrained, and it is hard to match the education-career-qualification based on NCS. Therefore, we study NCS from the definition to the utilization, suggest an improving method to flexibly utilized the standards in the fields, and continuously improve and develop the NCS.
