PURPOSE: The purpose of this study was to investigate the influences of depression, stress, and self-efficacy on the addiction to cell phone use among university students. METHODS: Data were collected through questionnaires from 563 students and analyzed by applying descriptive statistics, t-test, chi-square test, and stepwise multiple regression with SPSS/WIN 16.0. RESULTS: The proportion of depressed subjects was 52.6%. The addictive group scored higher than the non-addictive group in depression rate and stress, but scored lower in self-efficacy. Out of the subjects, 32.9% were found to be addictive users, 31.3% at potential risk, and 1.6% at high risk. Significant variables influencing addictive users were stress, self-efficacy, and the user's general characteristics including monthly spending money, sex, the hours of daily use, and the main method of use. CONCLUSION: It is concluded that such variables should be carefully considered in interventions for university students addicted to cell phone use.

OBJECTIVE: It is still the important subject that 3D visualizing of medical images to help patient diagnose. There were many challenges for fast 3D visualization but it has some limitations that volume rendering without high price's hardware and software. Some techniques through the web were suggested to construct high quality's 3D visualization even though it was an only poor personal computer. This technique could share the volume rendering board and diagnose 3D images together. However there are some problems to construct web based 3D visualization. These are network delay, optimized visualization and security etc. The purpose of this paper was to visualize and control the 3D medical image having a high quality on the web. METHODS: To construct this system, we used mainly three tools which were VolumePro1000 board, WMV9(Windows Media Video 9 Codec) and socket functions based on TCP(Transmission Control Protocol). VolumePro1000 board could calculate quickly heavy matrixes of 3D images using phong's shading and shear-warp factorization. WMV9 was able to compress efficiently live images and to apply image streaming technique. Socket functions based on TCP transmitted messages to control the 3D images. RESULTS: We developed 3D visualization system and evaluated about image qualities and transmission conditions of different compression rates on unfixed network condition. CONCLUSION: It was big advantages that WMV9 encoder could decode automatically in many platforms(desk top, PDA, notebook, cellular phone, etc) without installing specific decoding programs if they only have Windows Media player. We expect 3D visualization system to be utilized various biomedical fields such as IIGS(Interactive Image Guided Surgery), CAD(Computer Aided Diagnosis) and Tele-medicine technologies.

The concept of cellular reprogramming was developed to generate induced neural precursor cells (iNPCs)/dopaminergic (iDA) neurons using diverse approaches. Here, we investigated the effects of various nanoscale scaffolds (fiber, dot, and line) on iNPC/iDA differentiation by direct reprogramming. The generation and maturation of iDA neurons (microtubule-associated protein 2-positive and tyrosine hydroxylase-positive) and iNPCs (NESTIN-positive and SOX2-positive) increased on fiber and dot scaffolds as compared to that of the flat (control) scaffold. This study demonstrates that nanotopographical environments are suitable for direct differentiation methods and may improve the differentiation efficiency.

10.Development and Effects of a Prevention Program for Cell Phone Addiction in Middle School Students.
Journal of Korean Academy of Child Health Nursing 2011;17(2):91-99
PURPOSE: This study was done to develop a cell phone addiction prevention program for middle school students, and to examine the effects of the program on self-esteem, self-efficacy, impulsiveness, and cell phone use. METHODS: The study was designed using a nonequivalent control group pre-test-post-test design. The participants were 63 middle school students (31 in the experimental group and 32 in the control group). Students in the experimental group were given the cell phone addiction prevention program. The data were analyzed using the SPSS/WIN 14.0 program. RESULTS: Students in the experimental group reported a significant increase in self-esteem compared to students in the control group. Students in the experimental group also reported a significant decrease in cell phone use compared to students in the control group. CONCLUSION: The results of the study indicate that the cell phone addiction prevention program was effective in increasing self-esteem and decreasing cell phone use in middle school students.
