Precast Concrete apartments were main stream of domestic industrialized housing around 90's , and Steel Houses applying Steel Stud technique with light weighted steel have been dominant portion since 1995. On the other hand, various building techniques including Steel Stud method and highly prefabricated and industrialized Unit method are prevailing in developed countries like Japan. Steel Stud and Unit Box have their own merits and demerits, but the more crucial aspect is that the constant design standard should be applied in each design procedure. It entails the necessity of industrial housing development on the Open System basis. In this study, the design standard for Unit house will be established coping with the established preparing standard for design specifications defined by Architectural Law and Promotion Law of Housing Construction. That is for design standard of industrialized private housing on the Open System basis.

To avoid monotony of functionalistic architecture that may be considered the mainstream of modernism architecture, in recent days, the modern architecture displays diversified characteristics. Geometric manipulation method that creates an open space having manipulated a basic geometric shape like hexahedron (cutting out or joining the spatial area onto one side of the figure) is the space manipulation technique that has been introduced and emerged on a full scale since 1970. This technique has been developed as a type of living quarters that has equipped with passive control function, making outside climate flow into the interior. Recently methods for diversified space creation by means of geometry manipulation have begun to appear in domestic low rise multi-family housings other than inflexible box type high-rise building constructions, which comprise the mainstream of multi-family housing.

Purpose: We evaluated the efficacy of ultrasound-guided lower extremity nerve block in trauma patients. Methods: From July 2013 to April 2014, 17 patients with multiple trauma had lower extremity nerve block for immediate management of open wound in the lower extremity. We evaluated the patient satisfaction of the anesthesia and any complications related to the block. Results: During the lower extremity nerve block, incomplete nerve block occurred in one patient. This is the second case, the reason for this was the lack of technique. There was no anesthetic complications. Conclusion: Ultrasound-guided lower extremity nerve block in trauma patients is an effective anesthesia technique in the immediate management of open wound in lower extremities.

This study employed the Semantic Differential(SD) technique for an empirical analysis of the borrowed landscape-the so-called interaction of landscape between space and nature-in traditional Korean space against the cultural backdrop of confucian ideology. Its findings are as follows: First, the study conducted a comparative analysis of the borrowed landscape between Sarangchae(Men's quarters) and Anchae(Women's quarters) and between Soteuldaemun(A lofty gate) and Sadangdaemun(A gate to an ancestral shrine), using the SD technique. Consequently, their marked distinction in the borrowed landscape were found to illustrate the influence of confucian ideology over spatial composition. Second, both the garden and the sky of Sarangchae appeared more open and dynamic, and soft, and comfortable, and warm compared to Anchae. Also, Soteuldaemun looked more open and dynamic than Sadangdaemun. In conclusion, traditional Korean space applies a monistic view of the world to nature and human beings, thereby embodying a philosophical and aesthetic space where humans enjoy their life in harmony with nature while playing with the landscape in a traditional space.

Most open magnetic resonance imaging systems have used the planar gradient coils whose inductances were minimized through the magnetic energy minimization procedure in the spatial frequency domain. Though the planar gradient coils have smaller inductance than conventional gradient coils, the planar gradient coils often suffer from their poor magnetic field linearity. Scaling the spatial frequencies of the current density function designed by the magnetic energy minimization, magnetic field linearity of the planar gradient coils can be greatly improved with small sacrifice of gradient coil inductance. We have found that the figure of merit of the planar gradient coils, defined by the gradient strength divided by the linearity error and the inductance, can be improved by proposed technique.

In an open reduction of the mandibular angle fracture, it is crucial to approximate each fracture segment as closer as possible for the reduction of the healing period. In this case report, we proposed a new technique for the mandibular angle fracture. This was designed to minimize the gap between two separated segments using mini-implants and surgical wires. Mini-implants were placed around the fracture line, followed by wire ligation to minimize the fracture gap. And then internal fixation was easily employed with plates and screws. The advantages of this technique were reduced time for operation, the promotion of healing, rapid functional recovery, and few complications.

Large-scale low-alloy steel shafts, used in the manufacture of steam turbine, are produced by ingot making, forging and heat treatemtn processes. The numerical analysis techniques are introduced to analyze and design the working conditions in each process. The solidification of a steel ingot is studied through the finite element method. The open die press forging and quenching process are simulated by viscoplastic and elastic-plastic finite element method, respectively. Thus numerical analysis techniques are very useful tools to study favorable working conditions for better and more desirable product quality.

In the present study, a numerical prediction method on the hydrodynamic interaction force and moment between two ships in shallow and restricted waterway is presented. Especially, the present study proposes a methodology to overcome the limitation of the two dimensional perturbation method which is related to the moored-passing ship interaction. The validation study was performed and compared with the experiment, firstly. Afterward, in order to propose a methodology in terms with the moored-passing ship interaction, further studies were performed for the moored-passing ship case with a Reynolds Averaged Navier-Stokes (RANS) calculation which is using OpenFOAM with Arbitrary Coupled Mesh Interface (ACMI) technique and compared with the experiment result. Finally, the present study proposes a guide to apply the two dimensional perturbation method to the moored-passing ship interaction. In addition, it presents a possibility that the RANS calculation with ACMI can applied to the ship-ship interaction without using a overset moving grid technique.

The dielectric properties, dielectric constant (${\varepsilon}‘$) and loss factor (${\varepsilon}’$), of skin and pulp of fresh ginseng were measured from $25^{\circ}C$ to $67^{\circ}C$ using an open-ended coaxial probe technique for 915 MHz and 2450 MHz. Pulp and skin had dielectric constant of $30{\sim}64$ and loss factor between 10 and 20, each variable having a respective frequency dependence typical of materials with high water content. Although the loss factor was nearly constant, the dielectric constant increased as moisture content increased. The dielectric constant of ginseng pulp increased as temperature increased (temperature ${\leq}56^{\circ}C$), but any significant differences were not found in skin dielectric properties. Penetration depth for fresh ginseng were about 2 cm at 91.5 MHz and 1cm at 2450 MHz.

Games are widely used in many fields, but not all games are successful. Then what makes games successful? The question gave us the motivation of this paper, which is to identify critical factors for successful games with topic modeling technique. It is supposed that game reviews written by experts sit on abundant insights and topics of how games succeed. To excavate these insights and topics, latent Dirichlet allocation, a topic modeling analysis technique, was used. This statistical approach provided words that implicate topics behind them. Fifty topics were inferred based on these words, and these topics were categorized by stimulation-response-desiregoal (SRDG) model, which makes a streamlined flow of how players engage in video games. This approach can provide game designers with critical factors for successful games. Furthermore, from this research result, we are going to develop a model for immersive game experiences to explain why some games are more addictive than others and how successful gamification works.
