This study contains the results obtained after two and a half years of developing a knitting customization website using a knitting machine. Recently in the fashion world, various services using customization are being provided, and devices that users can design directly using knitting machines are being developed. However the existing website for knitting machine does not provide a certain usability or layout, so it is difficult for users to use open source and custom design. Therefore, this study was conducted for the purpose of developing a website that provides ease of use to users who will use the knitting customizing service using a knitting machine. As a research method, the first usability evaluation was conducted by synthesizing the studies conducted for the knit customization website development work. As a result of the study, found the problems of the initial custom screen and the initial output screen were found, and convenience, intuition, and readability were improved. Secondary usability evaluation was conducted on the modified website and it was confirmed that the problem was corrected. Through the website finally derived from this study, it is expected that the new platform in the domestic knit market will be popularized and the usability of the custom website will be improved.

On the design phase of small size bridge, owing to the lack of related guidelines or standards to determine a superstructure type of bridge, many designers tend to select the type depending on expert's experience and knowledge. Moreover, recently, as types of bridge superstructure become diverse and more conditions need to be considered in the project, the decision makes process become complex. This research covered the selection of a superstructure type of a middle or small size bridge with span length of about 50m, which frequently built for national roadway, selecting type of bridge superstructure more systematic way rather than the existing ways to compare construction methods or to depend on expert's experiences. This study proposes to build a bridge superstructure type selection model using one of the techniques of artificial intelligence techniques SVM by applicability of the model examined through the verification of the actual case.

Purpose: This study was done to investigate new graduate nurses' perceptions of nursing professionalism, job involvement and turnover intention and to identify factors influencing turnover intention in new graduate nurses. Methods: Participants were 179 new graduate nurses working in general hospitals and small and medium-sized hospitals in Gyungnam province. Data were collected from August 10 to September 16, 2015 through a survey with self-report questionnaires. Data were analyzed using descriptive statistics, t-test, ANOVA, $Scheff{\acute{e}}$ test, Pearson correlation coefficients, and multiple regression analysis. Results: Mean scores were; for nursing professionalism, $3.62{\pm}0.73$, for job commitment, $3.22{\pm}0.89$. and for turnover intention, $3.25{\pm}0.95$. There were significant correlations between nursing professionalism and job involvement (r=.47, p<.001), nursing professionalism and turnover intention (r=-.36, p<.001), job involvement and turnover intention (r=-.46, p<.001). For turnover intention of new graduates 25.1% of the variance was explained by nursing professionalism (${\beta}=-.16$, p=.034), job involvement (${\beta}=-.36$, p<.001), and frequency of night shifts (${\beta}=.03$, p=.022). Conclusions: Findings indicate that nursing professionalism and job involvement of new graduate nurses had significant influence on their turnover intention. Therefore, to reduce turnover intention of new graduate nurses, it is necessary to enhance their nursing professionalism and job involvement with organizational supports.

This paper is about an authoring interface for augmented/mixed reality based book, specifically authoring 3D objects properties of Digilog book. We pursue even normal users with non-professional knowledge for programming can make the Digilog book easily. An authoring interface 3D object properties includes a manipulator as an input device and 3D contents authoring parts. As an interface design metaphor, existing GUI interface, already familiar to computer users, are referenced. The manipulator generates continuous/discrete input signal are necessary for authoring interface. Contents authoring part performs selection, positioning, scaling, coloring, copy of virtual objects using the input signal of the manipulator. Also users can exploit already existing GUI interface metaphor including pointing, click, drag and drop, and copy techniques with the manipulator. Therefore we think our AR authoring system can support rapid and intuitive modification of properties of virtual objects.

Monitoring of groundwater Quality is essential for the preservation of groundwater resources. In practice. however, groundwater monitoring network is designed based on the experience and intuition of experts or on the convenience. This study proposes a simulation-optimization approach for the optimal design of monitoring networks. In it, the predicted three-dimensional concentration data are used as the input of an optimization problem. Various design objectives and constraints are considered and the problem is formulatcu as the 0-1 integer programming. The methodology was applied to a sanitary landfill site. The results show that the monitoring network configuration changes as the monitoring goal, operation time and constraints vary. The proposed method turns out to be an efficient tool for the wide range of groundwater Quality monitoring network design problems.oblems.

In this study, we hope to reveal teacher knowledge necessary to address student errors and difficulties about ratio and rate. The instruments and interview were administered to 3 in-service primary teachers with various education background and teaching experiments. The results of this study are as follows. Specialized content knowledge(SCK) consists of profound knowledge about ratio and rate beyond multiplicative comparison of two quantities and professional knowledge about the definitions of textbook. Knowledge of content and students(KCS) is the ability to recognize students' understanding the concept and the representation about ratio and rate. Knowledge of content and teaching(KCT) is made up of knowledge about various context and visual models for understanding ratio and rate.

As one measure of image interpretability, NIIRS(National Imagery Interpretability Rating Scale) has been used. Unlike MTF(Modulation Transfer Function), SNR(Signal to Noise Ratio), and GSD(Ground Sampling Distance), NIIRS can describe the quality of overall image at user's perspective. NIIRS is observed with human observation directly or estimated by edge analysis. For edge analysis specially manufactured artificial target is used commonly. This target, formed with a tarp of black and white patterns, is deployed on the ground and imaged by the satellite. Due to this, the artificial target-based method needs a big expense and can not be performed often. In this paper, we propose a new edge analysis method that enables to estimate NIIRS accurately. In this method, natural targets available in the image are used and characteristics of the target are considered. For assessment of the algorithm, various experiments were carried out. The results showed that our algorithm can be used as an alternative to the artificial target-based method.

We are suggesting an authoring tool can be used for prototyping in the augmented reality based product design environment. This tool is for authors without an engineering background to use. Our authoring tool can adjust the properties of visual, sound, and haptic feedback at the same time for more practical prototyping. Also the proposed modulated architecture can be applied flexibly to changes of platforms or hardware. Also user interfaces can be dynamically updated by changing just description files. finally, the suggested authoring methods exploit the advantages of both graphical and tangible user interfaces. Authors can intuitively make adjustments to many parameters using the TUI, and then they can do the same thing precisely using the GVI. The proposed authoring methods can be used for exhibition and entertainment contents using multi-sensory feedback in AR environment. As a future work, qualitative and quantitative usability test will be conducted.

Purpose : This study is a descriptive survey research that examines the effect of nursing students' satisfaction in major and consciousness of biomedical ethics on nursing professionalism. Methods : The research subjects consisted of junior and senior nursing students enrolled in four colleges located in City B, South Korea Structured questionnaires were distributed to the subject and a total of 262 copies of survey responses were analyzed. The collected data were analyzed by frequency, percentage, mean and standard deviation, t-test, and analysis of variance (ANOVA) using SPSS/WIN 22.0 program. The correlation relationship was investigated based on the Pearson correlation coefficient. Multiple regression was used to capture the effect on the nursing professionalism. Results : A positive correlation was observed between the nursing students satisfaction in major and consciousness of biomedical ethics (r=.280, p<.001), between satisfaction in major and nursing professionalism (r=.581, p<.001), and between consciousness of biomedical ethics and nursing professionalism (r=.290, p<.001). General satisfaction (β=.227, p=.001), and relationship satisfaction (β=.248, p=.000) among major satisfaction had the strongest prediction power for the nursing professionalism of nursing students, followed by right to life of fetus (β=.190, p=.000) among consciousness of biomedical ethics and motivation for admission (β=.137, p=.006). These predictors explained 36.9 % of the variable of nursing professionalism. Conclusion : Based on this study result, repeated studies are required that can confirm diverse influential factors on the nursing professionalism of nursing students. Operation of curriculums and development of programs that increase the nursing students' satisfaction in major and foster their nursing professionalism are required in the future.
