The root cause of the crack flaw occurred in construction. This crack is represented by a construction flaw occurs in the concrete structure. Therefore, we introduce the basic properties for the type of concrete to crack reduction measures to minimize the causes flaw this paper.

Forest management is done to keep ecological health of forest and to enhancement of its function. Nowadays, the abnormal climate and heavy rain happen frequently. Therefore, there are opinions that the thinning slash allowed in the mountain is flowed in rivers, which can influence in flood damage. This study, we grasp moving characteristics of thinning slash through field survey and achieved basic study about the effect of thinning slash on the discharge capacity of rivers and stream structure.

Fatigue strength analysis is one of the most important themes of ship structure design, as fatigue damages are reported on ship structures even now. But these need basic research workes which will take time. The others are the problem to apply fatigue strength analysis in design and have to be investigated in parallel with basic researches. The one of major items in the latter is the critical damage factor to define with S-N curve for fatigue strength analysis of ship structure design.

The structure of an antimicrobial peptide buforin II has been studied by $^1$H NMR and CD spectroscopy. Buforin II is flexible and random structure in H$_2$O but the parts of buforin II become helical structure in trifluoroethanol (TFE)/H$_2$O (1:1, v/v) solution. From the restrained molecular dynamics calculation using NMR data, we obtained the possible conformation of buforin II in TFE/H$_2$O solution. (omitted)

Silicene is one of the most interesting two-dimensional materials, because of not only the extraordinary properties similar to graphene, but also easy compatibility with existing silicon-based devices. However, non-existing graphitic-like structure on silicon and unstable free-standing silicene structure leads to difficulty in commercialization of this material. Therefore, substrates are essential for silicene, which affects various properties of silicene and supporting unstable structure. For maintaining outstanding properties of silicene, van der Waals bonding between silicene and substrate is essential because strong interaction, such as silicene with metal, breaks the band structure of silicene. Therefore, we review the stability of silicene on other two-dimensional materials for van der Waals bonding. In addition, the properties of silicene are reviewed for silicene-based heterostructure.

Objective: Data exchange, interoperability, and access as a service in healthcare information management systems (HIMS) is the basic need to provision health-services. Data existing in various HIMS not only differ in the basic underlying structure but also in data processing systems. Data interoperability can only be achieved when following a common structure or standard which is shareable such as semantics based structures. We propose web-enabler: A Hadoop MapReduce based distributed approach to transform the existing huge variety data in variety formats to a conformed and flexible ontological format that enables easy access to data, sharing, and providing various healthcare services. Results: For proof of concept, we present a case study of general patient record in conventional system to be enabled for analysis on the web by transforming to semantics based structure. Conclusion: This work achieves transformation of stale as well as future data to be web-enabled and easily available for analytics in healthcare systems.

NH3-pplasma treatment has been used for ppassivation of native-oxide-contaminated GaAs surface. Ex-situ band-gapp pphotoluminescence(ppL) measurement shows enhanced intensity for the treated surfaces. Auger electron sppectroscoppy(AES) shows that the treated surface contains nitrogen atoms but no arsenic atoms, which leads us to sppeculate that the graded GaN thin layer was formed on the surface. Based on these results, new metal-insulator-GaAs structure is ppropposed.
