Surface Image Velocimetry (SIV) is an instrument to measure water surface velocity by using image processing techniques. It gives us one of the easiest ways to measure water velocity. However, since it requires a set of plane survey data to estimate the velocity, it may give us some kind of misconcept that its usage would be difficult or cumbersome in spite of its handiness. If it has a feature that can estimate the plane survey data easily, it may be treated as like one of the conventional propeller velocimetries and its applicability would be improved so high. The present study is to propose a method to estimate the plane geometry of the physical coordinate with a calibrated camera. With the feature we can half-automatize the estimating procedure for the whole water velocity field. Photogrammetric technique to calculate the plane coordinates of the reference points with a calibrated camera was studied, which has originally studied for long time in the field of computer vision. By applying this technique to SIV, it is possible to estimate the location of reference coordinates for projective transform without plane survey. With this procedure the cumbersome plane survey for the reference points is omitted. One example application of the developed method showed fairly good results with insignificant errors.

This study was conducted to identify the factors influencing consciousness of biomedical ethics, moral sensitivity and critical thinking disposition with respect to the Code of Ethics of nurses among nursing students. A descriptive correlation research design was used for this study. The subjects were 299 nursing students in two large cities from 1 June to 31 July 2015. Collected data were analyzed using a t-test, ANOVA, Scheffe's test and stepwise multiple regression by the SPSS 22.0 program. The results revealed that female subjects comprised 86.65% of the subjects and the mean age was 21.67 years. Awareness of the Code of Ethics for nurses was positively correlated with the consciousness of biomedical ethics(p<0.001), moral sensitivity(p<0.001), and critical thinking disposition(p<0.001). However, there were negative correlations between grade(p=0.017), marital state(p=0.012), and the possibility of increasing ethical problems according to the development of bioscience(p=0.012). Significant influencing factors of the awareness of the Code of Ethics for nurses included grade(p=0.013), marital state(p=0.030), consciousness of biomedical ethics(p=0.017), moral sensitivity(p<0.001), and critical thinking disposition(p=0.001), with apower of explanation of 26.3%. The results of this study show that the consciousness of biomedical ethics, moral sensitivity and critical thinking disposition are factors influencing the code of ethics for nurses among nursing students.

Juam lake is a major water resource for the industrial and agricultural activities as well as the resident life of Kwangju and Chonnam area. However, the water quality of the lake is getting worse due to a large quantity of pollutant inflowing to the lake. As a preliminary step in making the countermeasure to achieve the water quality goal of the lake. it is necessary to understand how the water quality of the lake will be in future. Several computer programs can be used to predict the water quality of lake. Each of these programs requires a number of input data such as hydrological and meteorological data. and the quantity of the pollutant inflowed. but some or most of the input data contain uncertainty. which eventually results in the uncertainty of prediction value (future level of water quality). Generally. the uncetainty stems from the lack of information available. the randomness of future situation. and the incomplete knowledge of expert. Thus. the purpose of this study is to present a method for representing the degree of the uncertainty contained in input data by applying fuzzy theory and incorporating it directly into the water quality modeling process. By using the method. the prediction on the future water quality level of Juam lake can be made that is more appropriate and realistic than the one made without taking uncertainty in account.

As computer technology has been rapidly advanced, geographic information system (GIS) is recently used in many disciplines. In this study, for a model area in Seoul, seismic hazard potential relating to site effects, which are influenced by the subsurface geotechnical conditions, was estimated using the GIS tool. The distribution of pre-existing borehole drilling data in Seoul metropolitan area was examined for the regional estimation of site-specific seismic responses at the model area. Spatial geo-layers across the entire model area were predicted by constructing a GIS-based geotechnical information system (GTIS). A microzonation of site period $(T_G)$ for estimating site-specific seismic responses at the model area was performed within the GTIS. The spatial microzoning map of $T_G$ indicated seismic vulnerability of two- to four-storied buildings in the model area. Furthermore, a site classification map for determining the design ground motion was established based on the $T_G$ within the GTIS. This informed that most of location in the model area was categorized into current site classes C and D. This seismic microzonation framework for the model area could be applicable particularly in the entire Seoul metropolitan area based on the pre-existing borehole data.

The purpose of this study was to examine the effect of the film 'The Island' on 2nd year nursing students' nursing informatics (NI) competency. The participants were sixty-eight students in a baccalaureate nursing program of a private university, taking the course, 'Nursing & Informatics' in the 2012 fall semester. Over the 15 weeks, the film was used for five weeks as introduction to NI, peer-to-group discussions, and self-reflection on lessons learned regarding NI. A qualitative content analysis was used to explore the students' experiences and perceptions on their NI competency. As a result, students signified the NI concept as the assessment of biometrics data, promotion of optimal health with the support of various technologies, and integration of patient-centered care into routine practice. They also highlighted the importance of security and safety measures as well as high quality health technology including the ubiquitous health monitoring system. Overall, the lesson outcomes of the course were met. As a supportive, instructional strategy, the use of the movie, 'The Island', was effective for nursing students in achieving NI competencies. Further study is warranted to determine if movies can be used as a means of continuing education to improve informatics competences in healthcare professionals.
