Human mammary epithelial cells have different proliferative statuses and demonstrate a close relationship with age and cell proliferation. Research on this topic could help understand the occurrence, progression and prognosis of breast cancer. In this article, using significance analysis of a microarray algorithm, we analyzed gene expression profiles of human mammary epithelial cells of different proliferative statuses and different age groups. The results showed there were significant differences in gene expression in the same proliferation status between elderly and young groups. Three common differentially expressed genes were found to dynamically change with the proliferation status and to be closely related to tumorigenesis. We also found elderly group had less status-related differential genes from actively proliferating status to intermediate status and more statusrelated differential genes from intermediate status than the young group. Finally, functional enrichment analyses allowed evaluation of the detailed roles of these differentially-expressed genes in tumor progression.

Purpose: The purpose of this study was to survey periodontal status using oral health index in the elderly population and determine methods for improving oral health status. Methods: The date collected from 'The fifth korean national health and nutrition examination survey 2010' was analyzed in this study. Statistical analysis was done using the Statistical Package for Social Sciences version 19.0 for windows. We determined frequencies and percentage, calculating means, and standard deviations, and determining statistical significance using logistic regression analysis, multiple regression analysis. Results: General characteristics showed differences in oral health behaviors associated with gender, age, residence, education. General characteristics showed differences in periodontal status associated with gender, family type, gender, residence, education. Oral health behaviors showed differences in periodontal status associated with using oral health care products, dental treatment. Conclusion: In conclusion, in order to improve oral health of the elderly, the importance and needs of periodontal status should be emphasized. periodontal status related education for the elderly should be operated.

Purpose: The purpose of this study was to investigate health behavior, life satisfaction and stress in elderly people living in a rural community. Methods: The participants in this study were 198 elders from Y-county. Data were collected using a self-report questionnaire and analyzed through descriptive statistics, Pearson's correlation, t-test, ANOVA and Cronbach's ${\alpha}$. Results: There were statistically significant differences in stress according to the residential area. There were statistically significant differences in the health status of the elders according to age, education level, marital status, and presence of spouse. There were statistically significant differences in life satisfaction according to sex, marital status, education level, use of meeting facilities for elders and presence of spouse. The health status of the elders was also positively related to life satisfaction and negatively related to stress. Conclusion: The results of this study suggest that health status is a core factor determining the quality of life for elders. Therefore, a priority for gerontological nursing has to be a focus on improving the psychological and physical health for elders.

Objectives : The new health technology assessment system was introduced in April 2007. The purpose of new health technology assessment is assessing safety and efficacy in deciding a behavior of new health technology according to the Health Insurance Act. This study aims to understand the present status of new health technologies of Korean medicine. Methods : This research introduces new health technologies and their present status, and searches for a development direction for the new health technology of Korean medicine in the future. Results : Thirty seven cases(3%) of Korean medicine doctors who utilized new health technologies application were found. In the status about new health technologies application by technologies assortment, diagnostic test techniques were used more often than treatment skills. New medical technology that included korean medicine doctor as actual user was only one item, i.e. HCV antibody test. Conclusions : In order for the new health technology of korean medicine to settle down well, continuous interest and efforts of both government and medical community are necessary.

The purpose of this study is to explore the status of current ICT convergence technology in the agrifood area through reviewing articles. For this, we classified the ICT convergence technology into four categories including RFID technology, smart sensing technology, USN technology, and other ICT convergence cases and reviewed by extracting the cases related to the convergence technology that is recently conducted depending on each category from the Journal of Computers and Electronics in Agriculture between January 2012 and June 2014. Additionally, by combining the reviews of cases, we conducted the study in the direction of analyzing the recent ICT convergence technology status in the current agrifood area.

This paper presents an emergency brushless synchronous generator having rotating exciter status monitoring and protection functions. For monitoring the rotating exciter status, a wireless rotor status detector and a digital AVR(Automatic Voltage Regulator), which has a wireless communication capability, are proposed. The proposed rotor status detector detects temperatures of exciter armature and main field windings and input voltage and current of the main field. Therefore, it is possible to protect the generator from the over-temperature of windings and detect the exciter bridge diode fault. Furthermore, the proposed digital AVR has rotor status monitoring and protection function, and remote generator tuning, wireless group parallel operation function. So the operator can efficiently operate the generator using a smartphone from a remote area.

Mental status examination is an important stage in the assessment process because it serves as the foundation for establishing nursing diagnosis and intervention. Until now many students still feel difficult to understand the terms in the assessment of mental status. Interactive Mobile Learning in one of the media that is currently being developed. The use of this media will provide more in-depth learning opportunities, and students can practice their skills in carrying out practicals because of the mobility principle possessed by smartphones. The purpose of this study was to develop a smartphone-based app and evaluate the app's effectiveness by measuring nursing students' knowledge of mental status examination. Design: A randomized trial with a pre-and post-test design was conducted at a university in Indonesia. A total of seventy junior nursing students participated in this study. The intervention group received a smartphone-based app, and the control group received one-time lecture-based learning. We offered the experimental group the app and information about how to use it, and we encouraged them to use it. The control group received classroom instruction. Results: The intervention group scored significantly higher than the control group on knowledge score (t = 19.40, p = 0.000) and satisfaction with the learning method (t = 0.640, p = 0.021) Conclusion: These findings suggest that smartphonebased education could be an effective method in nursing education for teaching mental status examinations.

This paper deals with a parameter estimation of the DC-DC converter system for its diagnosis. Especially, we present the results of parameter estimation for the DC-DC converter model by the system identification method. The parameter estimation for the DC-DC converter system aims at the diagnosis of its operating status. For the operating status diagnosis of the DC-DC converter system, we assume that the DC-DC converter system is an equivalent model of the Buck converter and estimate the main parameter for on-line diagnosis. In addition, for verification of an estimated parameter, we compare a bode plot of the estimated system transfer function and measurement results of the HP4194 instrument. It is a control system analyzer for system transfer function measurement. Our results confirm that the main parameter for diagnosis of the DC-DC converter system can be estimated by the system identification method and that the aging status of the system can be predicted by these results on operating status.
