We report a method for optical monitoring of tumors in an animal model using optical coherence tomography (OCT). In a spectral domain OCT system, a superluminescent diode light source with a full width of 66 nm at half maximum and peak wavelength of 950 nm was used to take images having an axial resolution of 6.8 ${\mu}m$. Cancer cells of PC-3 were cultured and inoculated into the hypodermis of auricle tissues in BALB/c nude mice. We observed tumor formation and growth at the injection region of cancer cells in vivo and obtained the images of tumor mass center and sparse circumferences. On the $5^{th}$ day from an inoculation of cancer cells, histological images of the tumor region using cross-sectional slicing and dye staining of specimens were taken in order to confirm the correlation with the high resolution OCT images. The OCT image of tumor mass compared with normal tissues was analyzed using its A-scan data so as to obtain a tissue attenuation rate which increases according to tumor growth.

This is a convergence study to investigate the factors affecting the physical health status of college students and to present a strategy for effective program development. The participants of this study were 200 college students in a region and collected data by self-reported questionnaire. Data were analyzed by descriptive statistics, t-test, ANOVA, correlation analysis and stepwise multiple regression analysis. The results were as follows: 1) The physical-health status of the college students was positively correlated with the subjective perception of health status(${\beta}=-.323$, p<.01), health awareness(${\beta}=-.278$, p<.01), gender(${\beta}=-.197$, p<.01), and breakfast habit(${\beta}=-.192$, p<.01). And the explanatory power($R_2$) by 4 variables was 33.1%. As a result, it was confirmed that strengthening subjective perception, positive reinforcement of health awareness, and habit of breakfast were important for improvement of physical health status. Therefore, it is necessary to develop a health promotion program based on the factors influencing on the physical health status and to analyze its application effect.

Obesity causes inflammation and impairs thermogenic functions in brown adipose tissue (BAT). The adipokine lipocalin 2 (LCN2) has been implicated in inflammation and obesity. Herein, we investigated the protective effects of caloric restriction (CR) on LCN2-mediated inflammation and oxidative stress in the BAT of high-fat diet (HFD)-fed mice. Mice were fed a HFD for 20 weeks and then either continued on the HFD or subjected to CR for the next 12 weeks. CR led to the browning of the white fat-like phenotype in HFD-fed mice. Increased expressions of LCN2 and its receptor in the BAT of HFD-fed mice were significantly attenuated by CR. Additionally, HFD+CR-fed mice had fewer neutrophils and macrophages expressing LCN2 and iron-positive cells than HFD-fed mice. Further, oxidative stress and mitochondrial fission induced by a HFD were also significantly attenuated by CR. Our findings indicate that the protective effects of CR on inflammation and oxidative stress in the BAT of obese mice may be associated with regulation of LCN2.

This study was to explore the relationship between the job stress and mental health of nurses. The participants were 291 nurses from two general hospitals in C city. Job stress, mental health, and general characteristics of nurses were measured. The data were collected from April 7 to 30, 2015. The collected data was analyzed with descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression analysis. The mean score for job stress was 61.96 point and 92.45 for mental health. The mean scores for job stress were significantly different by age and turnover experience in nurses. Job stress was positively correlated with mental health(r=.233, p=.000). The findings indicate that job stress has an influence on mental health. We'd like to provide basic data on developing convergence programs to prevent and intervene job stress considering nurses' mental health problems in nursing service that is rapidly changing and specialized for the convergence generation.
