Purpose: The purpose of this study was to exam the effects of nursing information about intensive care unit environment on ICU patient's environmental stress, anxiety and comfort. Methods: A non-equivalent control group with non-synchronized quasi-experimental research design was used. Participants were 60 (control 30, experimental 30) patients who admitted at ICU in one hospital in Gangneung. Experimental group was provided with nursing information about intensive care unit environment. To avoid contamination of the experiment, data for the control group were collected prior to the experimental group. Paired t-test, t-test, chi-square test were used to analyze the data using the SPSS WIN 19.0 Program. Results: ICU environmental stress (t=-.089, p=.045) and anxiety (t=-5.65, p<.001) were significantly more reduced than before intervention. Also, comfort (t=-2.98, p=.036) was significantly more improved than before intervention. Conclusion: It confirmed that nursing information on ICU environment is effective in reducing environmental stress, anxiety and improving comfort in ICU patients.

There are currently about 6000 bacterial species with validly published names, but scientists assume that these may be less than 1% of bacterial species present on the earth. Microbial resource is one of the most important bioresources in bioinderstry and provides us with high economic values. To find missing ones, the studies of metagenome, metabolome, and proteome about microbes have started recently in developed countries. We construct the information system that integrates information on microbial genome resources and manages the information to support efficient research of microbial genome application, and name this system 'Bio-Meta Information System (Bio-MIS)'. Bio-MIS consists of integrated microbial genome resources database, microbial genome resources input system, integrated microbial genome resources search engine, microbial resources on-line distribution system, portal service and management via internet. In the future, we will include public database connection and implement useful bioinformatics software for analyzing microbial genome resources. The web-site is accessible at http://biomis.probionic.com

Purpose: The purpose of this study was to identify the relationships among knowledge, cancer information seeking behavior, and Willingness for education about Human Papillomavirus (HPV) vaccination among school teachers. Methods: The subjects were 135 teachers who had were working in the middle or high school in Korea. Data were collected by a self-report questionnaire, 2011. Data were analyzed by using the SPSS WIN 18.0 program. Results: There was a positive relationship between information seeking behavior and Willingness for education about HPV vaccination. There were differences in Willingness for education according to necessity of HPV vaccination for premarital women above 16-year old and marital women below 45-year old, and necessity of education for students. The Willingness for education were predicted by information seeking behavior, groups who HPV vaccination is necessary to premarital women above 16-year old, and HPV vaccination education for student is necessary. These variables explained 25.0% of the variance of the Willingness for education about HPV vaccination. Conclusion: The Willingness for education about HPV vaccination among middle or high school teachers could be improved by the emphasis of the preception that HPV vaccination is necessary to middle or high school students and is related to the prevention of cervical cancer.

Purpose: This study was to evaluate the effects of information on anxiety, blood pressure and pulse in cerebral angiography clients. Methods: The data were collected from June to November 2014. The participants were 42 (21 each for experimental and control group) patients who to received cerebral angiography. The information developed from researchers' materials for cerebral angiography was provided only to experimental group. Measured variables were anxiety, systolic and diastolic blood pressure, and pulse rate. Research tools for anxiety were Spielberger's state anxiety inventory, and 10 point visual analogue scale (VAS). Results: The difference in mean systolic blood pressure after intervention between the experimental group ($129{\pm}15.34$) and the control group ($141{\pm}17.70$) was statistically significant (t=-2.28, p=.028). The differences between the two groups in state anxiety, VAS anxiety, diastolic blood pressure, and pulse rate after intervention were not statistically significant (p>.05). Conclusion: The information using educational material was effective in to decreasing systolic blood pressure in patients who received cerebral angiography. Therefore this study material could be used as a nursing intervention for patients in cerebral angiography.

Temporal changes in the number of zooplankton species are important information for understanding basic characteristics and species diversity in marine ecosystems. The aim of the present study was to estimate the optimal monitoring frequency (OMF) to guarantee and predict the minimum number of species occurrences for studies concerning marine ecosystems. The OMF is estimated using the temporal number of zooplankton species through bi-weekly monitoring of zooplankton species data according to operational taxonomic units in the Tongyoung coastal sea. The optimal model comprises two terms, a constant (optimal mean) and a cosine function with a one-year period. The confidence interval (CI) range of the model with monitoring frequency was estimated using a bootstrap method. The CI range was used as a reference to estimate the optimal monitoring frequency. In general, the minimum monitoring frequency (numbers per year) directly depends on the target (acceptable) estimation error. When the acceptable error (range of the CI) increases, the monitoring frequency decreases because the large acceptable error signals a rough estimation. If the acceptable error (unit: number value) of the number of the zooplankton species is set to 3, the minimum monitoring frequency (times per year) is 24. The residual distribution of the model followed a normal distribution. This model can be applied for the estimation of the minimal monitoring frequency that satisfies the target error bounds, as this model provides an estimation of the error of the zooplankton species numbers with monitoring frequencies.

Ultrasonic and magnetic resonance imaging systems are used to visualize the interior states of biological objects. These nondestructive methods have many advantages but too much expensive. And they do not give exact color information and may miss some details. If it is allowed to destruct some biological objects to get the interior and exterior information, constructing 3D image from the series of the sliced sectional images gives more useful information with relatively low cost. In this paper, PC based automatic 3D model generator was developed. The system was composed of three modules. One is the object handling and image acquisition module, which feeds and slices objects sequentially and maintains the paraffin cool to be in solid state and captures the sectional image consecutively. The second is the system control and interface module, which controls actuators for feeding, slicing, and image capturing. And the last is the image processing and visualization module, which processes a series of acquired sectional images and generates 3D graphic model. The handling module was composed of the gripper, which grasps and feeds the object and the cutting device, which cuts the object by moving cutting edge forward and backward. Sliced sectional images were acquired and saved in the form of bitmap file. The 3D model was generated to obtain the volumetric information using these 2D sectional image files after being segmented from the background paraffin. Once 3-D model was constructed on the computer, user could manipulate it with various transformation methods such as translation, rotation, scaling including arbitrary sectional view.
