Purpose: This study aimed to identify the factors influencing competency for Multi-Drug Resistant Organisms (MDRO) infection control in nursing students with clinical practice experience. Methods: This cross-sectional descriptive study was conducted from May 2020 to August 2020 by including 175 nursing students in two nursing schools located in Daegu. The data were collected using self-report questionnaires. The data were analyzed using the SPSS/WIN 25.0 program with descriptive statistics, independent t-test, ANOVA, correlation, and multiple regression. Results: The competency of MDRO infection control was 3.41.±0.38. The attitude to patient safety management and - knowledge of MDRO infection control were 3.81±0.47 and 16.98±3.02, respectively. Factors influencing the competency of MDRO infection control were perceived benefit(β=.38, p<.001), knowledge toward MDRO infection control(β=.21, p=.001), attitude in patient safety management(β=.17, p=.028), and perceived barrier(β=-.15, p=.029) with an explanatory power of 34.2%. Conclusion: A systemic education program regarding MDRO infection control is needed for nursing students to provide knowledge related to MDRO infection control and help establish positive beliefs toward MDRO infection control and attitudes in patient safety management.

Disposal cover as an engineered barrier of a near-surface disposal facility for low and very low-level radioactive waste is composed of a multi-layer to isolate radioactive waste from environmental influences for the long term. To acquire a realistic forecast for the post-closure period of the disposal facility, it is essential to carry out long-term experimental research in a similar condition to the actual disposal environment. Hence, a performance test facility of the disposal cover was constructed in Gyeongju low and intermediate level radioactive waste disposal center in 2022. The constructed performance test facility has differences from the material properties presented in the design. These differences are factors that affect the prevent rainfall infiltration, which is one of the important roles of the disposal cover. Therefore, in this study, a numerical simulation of rainfall infiltration into the performance test facility was performed for the designed case and the actual constructed case. To simulate the behavior of water infiltration, the FEFLOW software based on the finite element method is used. Through the analysis of numerical simulation results, it is confirmed that the hydraulic conductivity of the material constituting the multi-layer of the disposal cover greatly influences the amount of water infiltration.

This paper develops a model of customer satisfaction in the mobile telecommunication services. We examine the relationships among customers'overall satisfaction and underlying dimensions； perceived service quality, service value, and brand image. Variables related to customer satisfaction and dissatisfaction are derived from customer critical incidence survey. The model is estimated with multi-variate data analysis. Results indicate that the (1) technical service quality is the main driver of customer overall satisfaction, (2) some peripheral services are rapidly evolving into the core services of mobile telecommunications, and (3) the current policy of service providers does not focus on customer satisfaction but on establishing churning barrier by increasing switching costs.

A plastic substrate for flexible display is developed. The developed PES film has good resistance to heat, low intrinsic birefringence, and mechanical stability. The gas barrier property in the substrate is improved through depositing organic and inorganic multi layer on plastic film by PVD and CVD process.

Seattle Public School Authority implements Inclusive Education which allows handicapped children to study in ordinary schools. This research is to analyze Inclusive Education system and find characteristics of school network and school planning. Survey was performed on 9 school districts and 54 public schools. The found results are following; 1) 54 schools adopt special education programs and legal barrier free design. All handicapped children groups are divided into level I through Ⅳ including mild level (level I,II) at all schools and multi-handicapped(severe level, level III, IV) at schools specified by school district or Seattle City. 2) Each school groups are transformed into self-contained classroom, therapy room and general room as a set in consideration of user communication and special education program. Also, existing classrooms are rearranged into small study spaces by using partition system. It allows ordinary schools to accomodate Inclusive Education through school network, classroom rearrangement and space partitioning.

In the present paper, the hydrodynamic properties of a Rahmen type flexible porous breakwater with dual fixed pontoon system interacting with obliquely or normally incident small amplitude waves are numerically investigated. This system is composed of dual vertical porous membranes hinged at the side edges of dual fixed pontoons, and a submerged horizontal membrane that both ends are hinged at the steel frames mounted pontoons. The dual vertical membranes are extended downward and hinged at bottom steal frame fixed into seabed. The wave blocking and dissipation mechanism and its effects of permeability, Rahmen type membrane and pontoon geometry, pretensions on membranes, relative dimensionless wave number, and incident wave headings are thoroughly examined.

A step-up option is a newly developed financial instrument that simultaneously provides higher security and profitability. This paper introduces two step-up options: step-up type1 and step-up type2 options, and derives the option pricing formulas using the Laplace transform. We assume that the underlying equity price follows a regime-switching model that reflects the long-term maturity of these options. The option prices are calculated for the two types of funds, a pure stock fund composed of risky assets only and a mixed fund composed of stocks and bonds, to reflect possible variety in the fund underlying asset mix. The impact of changes in the model parameters on the option prices is analyzed. This paper provides information crucial to product developments.

In this article, the present activities regarding research and development of continuous SiC fiber reinforced ceramic matrix composites (CFCC) in Japan are reviewed. The key technologies in SiC fiber composites are interphase between fiber and matrix and its oxidation resistance. To improve oxidation resistance of interphase, various kinds of technologies such as environment barrier coating, high dense matrix, unti-oxidation matrix, multi-layered intephase have been developed. It is suggested that high performance, affordable processing cost, and excellent reliability will be important factors to be in practical use of CMCs in future.

AFM tip has been used for surface profiling with a fine resolution, but there is a barrier to improve its performance because of the low aspect ratio. Many researchers have solved this problem with attaching carbon nanotube (CNT) to Si-tip. In this paper, we proposed the aligner system that composed of dual type stage system, and these stages could attach a carbon nanotube to tungsten-tip in vacuum condition. We used tungsten tip instead of Si-tip because of its conductivity. The aligner system proposed in this paper has 10 degree-of-freedom that 3 in the first stage and 7 in the second stage. With picomotors and piezotube, the first stage has the resolution about several tens of nm and the second stage has a resolution about a nm. We experimented on characterization of Nano Aligner System and operated picomotors in SEM environment.

People frequently feel the need of a general searching tool that frees from language barrier when they find information through the internet. Therefore, it is necessary to have a multilingual parallel corpus to search with a word that includes a search keyword and has a corresponding word in another language, Multilingual parallel corpus can be built and reused effectively through the several processes which are judgment of the web documents, sentence alignment and word alignment. To build a multilingual parallel corpus, multi-lingual dictionary should be constructed in each language and HTML should be simplified. And by understanding the meaning and the statistics of document structure, judgment on translated web documents will be made and the searched web pages will be aligned in sentence unit.
