This study uses a structural equation model for the turnover intention of female nurses performing shift work at a tertiary hospital. Data collection was conducted from November 11 to December 20, 2015, and 283 samples were included in the final analysis. As a result, 12 of the 19 hypotheses of the final model were supported. It was confirmed that external employment opportunities, nursing professional value, nursing organizational culture, job stress, job satisfaction, organizational commitment, and burn out accounted for 47.8% of the turnover intention. Burn out(+) and organizational commitment(-)had direct effects on turnover intentions, and nursing professional, relationship-oriented nursing organizational culture, and job stress showed indirect effects. Therefore, in order to reduce the turnover intention of female nurses working in shifts at tertiary hospitals, it is necessary to prevent burnout, increase organizational commitment, and job satisfaction. For this purpose, measures to strengthen relation-oriented nursing organizational culture and nursing professional intuition are required. In terms of hospital manpower management, the institutional arrangements of hospitals that enable flexible working hours adjustment, mutually respectful relationship-centered organizational culture, education, and policy support to reinforce nursing professional intuition, and the institutional system of hospitals to work with pride should be implemented.

Paradigm shift in government services means the evolution to the service with active participation based on information technology. Opening public information proceeds to an extent that private sector participation can be a basis and driving force, and extends to a stage that free and practical use is possible for private sector. Therefore, the government is preparing for legal and institutional foundation for various fields. The government needs to build open network from user-oriented point of view rather than provider-centric point of view, improve communication, and change the way of working due to the fact that flexible and rapid business process is required. It is time to prepare development plans for public the functions of platform-type government that public sector can participate in the role of government, create new value, and give rise to innovation in order to change the functionality of the government and meet the new needs of citizen. This study tries to analyze platform-type government and to study efficient role allocation for sharing resources including informant and system between the government and the private sector, focusing on innovation of public information sharing.

Low temperature SiOx film process has being required for both silicon and oxide (IGZO) based low temperature thin film transistor (TFT) for application of flexible display. In recent decades, from low density and high pressure such as capacitively coupled plasma (CCP) type plasma enhanced chemical vapor deposition (PECVD) to the high density plasma and low pressure such as inductively coupled plasma (ICP) and electron cyclotron resonance (ECR) have been used to researching to obtain high quality silicon oxide (SiOx) thin film at low temperature. However, these plasma deposition devices have limitation of controllability of process condition because process parameters of plasma deposition such as RF power, working pressure and gas ratio influence each other on plasma conditions which non-leanly influence depositing thin film. In compared to these plasma deposition devices, neutral beam assisted chemical vapor deposition (NBaCVD) has advantage of independence of control parameters. The energy of neutral beam (NB) can be controlled independently of other process conditions. In this manner, we obtained NB dependent high crystallized intrinsic and doped silicon thin film at low temperature in our another papers. We examine the properties of the low temperature processed silicon oxide thin films which are fabricated by the NBaCVD. NBaCVD deposition system consists of the internal inductively coupled plasma (ICP) antenna and the reflector. Internal ICP antenna generates high density plasma and reflector generates NB by auger recombination of ions at the surface of metal reflector. During deposition of silicon oxide thin film by using the NBaCVD process with a tungsten reflector, the energetic Neutral Beam (NB) that controlled by the reflector bias believed to help surface reaction. Electrical and structural properties of the silicon oxide are changed by the reflector bias, effectively. We measured the breakdown field and structure property of the Si oxide thin film by analysis of I-V, C-V and FTIR measurement.

Rem Koolhaas has pursued new architectural approaches breaking with conventional ones. Around the 1990s when large-scale projects occurred with the union of Europe ahead, Koolhaas recognized the limits to the existing methods for responding to such changes. Accordingly, he came to use design methods based on 'congestion' and 'void' as strategical alternatives, which became the moment for him to leap forward from the previous working sphere based in Europe to becoming an architect who would be commissioned a number of large-scale global projects. Therefore, this study intends to investigate his design methods which utilized congestion and void, and to derive spatial characteristics from the projects based on such methods. First of all, the study looked into the historical background, definition and process of congestion and the void as design methods, and analyzed his projects to which such methods were applied by classifying them into the following categories: 1) the void that removes a space of singularity; 2) the void that penetrates space while making a flow; and 3) the void that is formed by vertical extrusion. Then, the characteristics of architectural spaces made in this way were identified as 1)the single-body appearance made by congestion and the following types of space made by the void: 2) the non-uniformly shaped space that looks like floating; 3) the flexible space with various flows and directions; and 4) the space with virtual possibilities that embrace contingent events. This understanding of Rem Koolhaas's design methods which were attempted in various ways at his critical turning point will be the foundation to understand the overall world of his works.

The current design paradigm shift which has been in progress around the world would be a good opportunity for Korea, which has led the age of information, to build design competence and gain international competitiveness. In addition, it would be a good idea for colleges as well as firms to develop a new educational system and create academia-industry-research synergy. This paper researches the market KU project promoted by Design Venture KU which has been established by the College of Artand Design of Konkuk University as a part of differentiation strategy. The methods to improve the competitiveness of Korean fashion design by uniting college creativity and market practicality are as follows: First, for convergence of creativity and practicality, it is necessary to come up with a systematic design-based educational system. In other words, the undergraduate program needs to gradually expand courses by focusing on creativity instead of functions while the graduate program should be able to develop design pattern, textile and marketing products and secure the market to gain competitiveness as a business incubator. Second, the working-level engineers as well as professors will be encouraged to participate in special lectures or seminars and take necessary lessons. In addition, academia-industry cooperation courses will be further strengthened. It is also important to actively participate in an official contest or exhibition and receive a prize. Third, to elicit creativity from students, it is necessary to help them think in a flexible and experimental way with voluntary and interesting programs. As mentioned above, it is expected that 'Market KU Project' would help students build expertise by offering them a chance to experience the real world and become the world's leading designers in Korean fashion design.

For the silicon oxide $(SiO_x)$ films prepared by using the facing target sputtering (FTS) apparatus that was manufactured to enhance the preciseness of the fabricated thin-film and sputtering yield rate by forming a higher-density plasma in the electrical discharge space for using it as a thin-film passivation system for flexible organic light emitting devices (FOLEDs). The deposition characteristics were investigated under various process conditions, such as array of the cathode magnets, oxygen concentration$(O_2/Ar+O_2)$ introduced during deposition, and variations of distance between two targets and working pressure. We report that the optimum conditions for our FTS apparatus for the deposition of the $SiO_x$ films are as follows: $d_{TS}\;and\;d_{TT}$ are 90mm and 120mm, respectively and the maximum deposition rate is obtained under a gas pressure of 2 mTorr with an oxygen concentration of 3.3%. Under this optimum conditions, it was found that the $SiO_x$ film was grown with a very high deposition rate of $250{\AA}$/min by rf-power of $4.4W/cm^2$, which was significantly enhanced as compared with a deposition rate (${\sim}55{\AA})$/min) of the conventional sputtering system. We also reported that the FTS system is a suitable method for the high speed and the low temperature deposition, the plasma free deposition, and the mass-production.

Continuously motivating people to exercise regularly is more important than finding a way out of barriers such as lack of time, cost of equipment, lack of nearby facilities, and poor weather. Our proposed system presents practicable methods of motivation through a diverse exercise aid system. The Health Improvement and Management System (all-in-one system which saves space and maintenance costs) measures and evaluates a diverse body shape analysis and physical fitness test and directs users to automated personalized exercise prescription which is prescribed by the expert system of three types of exercise templates: aerobics, anaerobics, and leisure sports. Automated personalized exercise prescriptions are built into XML based documents because the data needs to be in the form of flexible, expansible, and convertible structures in order to process various exercise templates, BIOFIT, a digital exercise trainer, monitors and provides feedback on the physiological parameters while users are working out in the gymnasium. If these parameters do not range within the prescribed target zone, the device will alarm users to control the exercise and make the exercise trainer adjust systemically the proper exercise level. Numeric health information such as the report of the physical fitness test and the exercise prescription makes people stay interested in exercising. In addition, this service can be delivered through the Internet.

Long-span cable-supported bridges are flexible structures vulnerable to unsymmetric loadings such as railway traffic and strong wind. The torsional dynamic response of long-span cable-supported bridges under running trains and/or strong winds may deform the railway track laid on the bridge deck and affect the running safety of trains and the comfort of passengers, and even lead the bridge to collapse. Therefore, it is eager to figure out the torsional dynamic response of long-span cable-supported bridges under running trains and/or strong winds. The Tsing Ma Bridge (TMB) in Hong Kong is a suspension bridge with a main span of 1,377 m, and is currently the world's longest suspension bridge carrying both road and rail traffic. Moreover, this bridge is located in one of the most active typhoon-prone regions in the world. A wind and structural health monitoring system (WASHMS) was installed on the TMB in 1997, and after 17 years of successful operation it is still working well as desired. Making use of one-year monitoring data acquired by the WASHMS, the torsional dynamic responses of the bridge deck under rail traffic and strong winds are analyzed. The monitoring results demonstrate that the differences of vertical displacement at the opposite edges and the corresponding rotations of the bridge deck are less than 60 mm and $0.1^{\circ}$ respectively under weak winds, and less than 300 mm and $0.6^{\circ}$ respectively under typhoons, implying that the torsional dynamic response of the bridge deck under rail traffic and wind loading is not significant due to the rational design.
