Microarray expression datasets are incessantly cumulated with the aid of recent technological advances. One of the first steps for analyzing these data under various experimental conditions is determining differentially expressed genes (DEGs) in each condition. Reasonable choices of thresholds for determining differentially expressed genes are used for the next -step-analysis with suitable statistical significances. We present a model for identifying DEGs using pathway information based on the global connectivity structure. Pathway information can be regarded as a collection of biological knowledge, thus we are tying to determine the optimal threshold so that the consequential connectivity structure can be the most compatible with the existing pathway information. The significant feature of our model is that it uses established knowledge as a reference to determine the direction of analyzing microarray dataset. In the most of previous work, only intrinsic information in the miroarray is used for the identifying DEGs. We hope that our proposed method could contribute to construct biologically meaningful network structure from microarray datasets.

Purpose: This study was conducted to describe the meaning units of the teaching experience of Tai Chi instructor with nursing background, consequently to expand areas where nurses can work. Methods: Participants were four nurses who have worked as Tai Chi instructors for 5 to 8 years. An in-depth interview was conducted from June, 2010 to February, 2011. Each interview took 40 min to 4 hours. The data were analyzed with qualitative content analysis, by repeatedly listening to the tapes and reading the transcription to find the emerged meaningful words, phrases, and sentences. Results: Through the content analysis, 19 theme clusters were emerged and grouped together into seven categories: 'establishing my identity as an instructor', 'enjoying myself practicing Tai Chi', 'being confident about teaching Tai Chi with nursing background', 'exploring better ways to teach and motivate the class', 'feeling good about helping people to be healthy', 'accepting teaching Tai Chi as a lifetime job', 'contributing to health promotion with Tai Chi." Conclusion: Teaching and helping others to promote health were parts of nursing. Tai Chi can be used to promote health in the low-income population with limited access to health care system.

The purposed of this research was to suggest a basic material of Korean-typed cohousing plan for a dual-income family by examining the difference of cohousing residing environment needs. Selecting Employed and unemployed housewives as this research's subject, the following results were drawn from the analysis between the two groups. 1) The housewives takes responsibility of the household works regardless of whether or not they are employed. Also, more than half of employed housewives stated that the time of nursery facilities was shorter than their needs and that they favored a nursery facility located inside the residential area. 2) The most meaningful difference of cohousing residing environment needs was the demand for sharing household work in terms of cohousing need of the subjects. The desirable cohousing area is the suburbs of the metropolitan areas and the preferable resident organization is need to be organized by people sharing the same goal through an announcement. 3) The need of cohousing and residence intention were generally low, but the employed housewives' need was higher than the unemployed ones.

This work introduces a two-module robotic pipe inspection system with ultrasonic NDE device to evaluate the integrity of pipe structures. The proposed robotic platform has high mobility. The two module mobile robot platform overcomes pipe obstacle structures such as elbow, or T-branch joints by cooperative maneuvers. Also, it can climb up the straight pipeline at a fast speed due to the wheel driven mechanism. For inspection of pipe structure, SH-waves generated by EMAT are applied with additional signal processing methods. A wavelet transform is implemented to extract a meaningful and specific signal from the superposed SH-wave signals. Intensity ratio which is normalized the defect signals intensity by the maximum intensity of directly transmitted signals in the wavelet transforms spectrum is applied to evaluate defects quantitatively. It is experimentally verified that the robotic ultrasonic inspection system with EMAT is capable of non-destructive inspection and evaluation of defects in pipe structure successfully by applying signal processing method based on wavelet transform.

Purpose: The purpose of this study was to develop a measurement tool of nurse's turnover intention. Methods: Data were collected from questionnaires completed by 678 nurses who worked in 3 university hospitals in South Korea and analyzed using the SPSS 18.0 and AMOS 18 programs. Thirty-seven preliminary items were selected from 161 basic items extracted via a literature review and in depth interviews with 6 hospital nurses. Three steps with factor analysis were undertaken to verify the reliability and validity of the preliminary instruments. Finally, confirmative factor analysis was carried out. Results: As a result of the analysis, 3 factors including 10 items were selected. Cronbach's Alpha for the 10 items was .83, for job satisfaction (4 items), .78, for interpersonal relationships (3 items), .80, and for work performance (3 items), .74, which was stable. Conclusion: This study is meaningful because through it a scale reflecting Korean culture was developed to measure turnover intention in nurses. Further studies that test the psychometrics of this scale in more diverse samples are warranted.

High contrast grating (HCG) is the structure made up of the sub-wavelength grating of high-index and the surrounding layer of low-index, which reveals high contrast between two materials. Its advantages include high reflectivity over a broad bandwidth, polarization and wavelength selectivity, optical high-Q resonator, and phase modulation. In this work, the HCG structure comprising of indium tin oxide (ITO) and Silicon (Si), for the surrounding layer and the grating layer respectively, was studied. Its theoretical model was established, and transmittance, phase and optical behavior were calculated by rigorous coupled-wave analysis and finite element method. Furthermore, the established structure was fabricated to validate its feasibility. The fabricated structure shows the focusing capability whose length is about $10{\mu}m$, and the feasibility of the structure was demonstrated. It is also meaningful that ITO layer can contribute to the fabrication of the HCG structure, leading to enable the structure to be electrical-driven.
