Currently, user demands for Hanok, the Korean traditional building type, are increasing in Korea, and their use as residences and accommodations are especially booming, while public facilities are rarely built in the style of Hanok these days. One of the most critical reasons for the issue is that Hanok lack usability and are difficult to maintain as a public facilities. Therefore, it is improvement of the usability of Hanok is needed for them to be accepted as public buildings and to set up the maintenance strategy for the style of the wooden structure. This research has defined public buildings in Hanok and classified them into three types according to structural standards. Then, this study analyzed the characteristics of each type, and suggested a checklist for Hanok usability, employing it to analyze the most recent exemplar Hanoks built as results in the governmental research project, monitored them in aspects of the facility management focused on the wooden structure and suggested strategies for sustainability by deriving eight factors in usability and another eight major types of defects to review the current status of the maintenance for the wooden structure. Finally, this study proposed the main direction for Hanok maintenance to establish its strategies for sustainability.

Data Assessment

In the final evaluation for the application of the Master Curve in the IAEA Coordinated Research Project Phase 5 (CRP-5), one of the areas which was identified as needing further work concerned the effects of loading rate on the reference temperature To up to impact loading conditions. This subject represents one of the three topic areas within the current CRP-8. The effect of loading rate can be broken down into two distinct aspects: 1) the effect of loading rate on the Master Curve To values for loading rates within the specified in ASTM E1921-05 for quasi-static loading (0.1–2 MPa√m/s); 2) the effect of loading rate on To values for higher loading rates, including impact conditions using instrumented precracked Charpy (PCC) specimens. The new CRP includes both aspects, but primarily focuses on the second element of loading rate effects, i.e. loading rates above 2 MPa√m/s. These issues are investigated within the topic area #2 of CRP-8 (Loading Rate Effect). The mandatory portion of this topic area required participation in a round-robin exercise (RRE) to validate the application of the Master Curve approach to PCC specimens tested in the ductile-to-brittle transition region using an instrumented pendulum (10 tests per participant on the JRQ material). The current status of the RRE is presented in [1]. The non-mandatory portion of this topic area consists in providing Master Curve data obtained at different loading rates on various RPV steels, in order to assess the loading rate dependence of To and compare it with an empirical model proposed by Wallin. Moreover, additional topics will be addressed, such as: • comparison of results from unloading compliance and monotonic loading in the quasi-static range; • estimation of fracture toughness from Charpy V-notch data; • assessment of crack arrest properties from instrumented Charpy results; • effect of irradiation on the relationship between static and dynamic fracture toughness.

Numerical Investigations

During the 2012 outage of the Belgian nuclear power plants (NPP) Doel 3 and Tihange 2 non-destructive testing (NDT) measurements revealed a high quantity of indications in the upper and lower core shells of the reactor pressure vessels (RPV). A root cause analysis leads to the most likely hypothesis that the indications are hydrogen flakes in segregated zones of the RPV ferritic base material. The laminar and quasi-laminar orientation (0° – 15° inclination to the pressure retaining surface) of the hydrogen flakes, the interaction of several adjacent flakes and the mechanical loading conditions lead to a mixed-mode behavior at the crack tips. In the framework of an ongoing research project, experimental and numerical investigations are conducted with the aim to describe the failure behavior of such complex crack configurations. The experiments are carried out using two ferritic materials. One is a non-irradiated representative RPV steel (SA 508 Class 2) and the second material is a special lower bound melt of a modified 22NiMoCr3-7 steel (FKS test melt KS 07 C) containing hydrogen flakes. A material characterization is done for both materials including tensile specimens, notched round bars, shear-, torsion- and compact-tension-shear (CTS) - specimens to investigate different stress states. Furthermore, flat tensile specimens with eroded artificial crack fields are used to investigate the interaction between the cracks in different arranged crack fields. Numerical simulations are carried out with extended micromechanical based damage mechanics models. For the description of ductile failure an enhanced Rousselier model is used and an enhanced Beremin model to calculate the probability of cleavage fracture. To account the sensitivity for low stress triaxiality damage by shear loading, the Rousselier model was enhanced with a term to account for damage evolution by shear. The Beremin model will be enhanced with a term to account for different levels of triaxiality. For the numerical simulations in the transition region of ductile-to-brittle failure a coupled damage mechanics model (enhanced Rousselier and Beremin) will be used. In this paper, the current status of the ongoing research project and first results are presented.

IntroductionThe use of patient-reported outcome measures in psychiatric practices in the United States is still in its beginning phases. More research is need to determine the usefulness of such measures and the optimal methods to present them to patients and practitioners in routine care settings.ObjectivesThis presentation will describe the research plan for testing a group of patient-reported outcome measures using digital applications. Potential opportunities for use in underserved refugee populations will be presented.MethodsThe outcome measures were selected from those recommended in DSM-5 Section III, including cross-cutting symptom and disability measures. A user-friendly digital application was developed for data collection, synthesis, and presentation. The research plan has three phases: focus groups with patients and clinicians, piloting of methods, and the main study, a pragmatic trial comparing treatment outcomes using outcome measurement versus usual care.ResultsResults of the focus group sessions will be presented, along with changes made to the measures and the digital application in response to these results. Current status of the research project will be discussed.ConclusionsThe results of this research project will bring greater clarity to questions on the role of outcome measurements in improving quality of care and patient outcomes. With ever greater use of smart phones, tablets, and personal computers, digital technology has the potential to facilitate psychiatric assessment and treatment for underserved, difficult-to-reach populations such as refugees.Disclosure of interestThe authors have not supplied their declaration of competing interest.

The aim of this article is to summarize knowledge regarding dispute about Koguryo territorial and historical affiliation, which occurred on the political and academic level. Between 37 BC and AD 668 ancient Kingdom of Koguryo embraced large area from central Manchuria to south of Seoul. After year 1945, when Korea regained independence Korean researchers were able to begin their studies on the foundation of the national identity. According to the “Serial Research Project on the History and Current status of the Northeast Border Region” started in China in 2002, Koguryo was an ethnic system in one of the provinces in ancient China. Through this project Chinese historians and archaeologists wanted to incorporate history of Koguryo into the Chinese history, which was not acceptable to Korean researchers. Because of such approach from both sides to this issue, both countries were forced to use archeological excavations and obtained relics in order to show the connection between past and present in both, Koguryo-China and Koguryo- Korea history.

Electron Microscopes

Solid state x-ray sensing systems have been used for many years in conjunction with scanning and transmission electron microscopes. Such systems conveniently provide users with elemental area maps and quantitative chemical analyses of samples. Improvements on these tools are currently sought in the following areas: sensitivity at longer and shorter x-ray wavelengths and minimization of noise-broadening of spectral lines. In this paper, we review basic limitations and recent advances in each of these areas. Throughout the review, we emphasize the systems nature of the problem. That is. limitations exist not only in the sensor elements but also in the preamplifier/amplifier chain and in the interfaces between these components.Solid state x-ray sensors usually function by way of incident photons creating electron-hole pairs in semiconductor material. This radiation-produced mobile charge is swept into external circuitry by electric fields in the semiconductor bulk.
