Aging causes a variety of changes in the structure of the vocal fold (VF), resulting in aging-induced dysphonia (presbyphonia). Several studies have investigated the structure of the VF of elderly people from autopsy as well as animal studies. There is an increasing evidence on correlation of structural changes of VF with deteriorated voice in elderly. Although the cellular mechanisms of aging VF have only partially been elucidated, there are many recent advances in biological treatment on aging VF using bioactive molecules such as growth factors. In this study, I'd like to address aging-related structural, biological, and physiological changes in previous literature about human and rodent aging VFs, to provide further insight into the mechanisms responsible for presbyphonia and to translate the basic researches for future clinical trials.

Technology Acceptance Model (TAM) has been a basis model for testing technology use. Post researches of TAM have been conducted with the updating the TAM by adding new independent variables in order to increase the explanation power of the model. However, one problem is that different independent variables have to be introduced to keep the explanation power whenever applying to particular technology. This reduces the generality of the research model. Thus in order to increase the generality of the model, this study reviewed the previous researches and collected the independent variables used, and regrouped them into three basic independent constructs. New research model was designed with three basic independent constructs with four constructs selected for the mandatory IT environment and voluntary IT environment, and the structured equations analysis(AMOS) was applied to find the significant causal effect relationships between constructs in addition to the explanation power of the model. Finally, this study concluded that new TAM could be used to explain the users' adopting new technology without any adding new particular independent variables.

Technology Acceptance Model (TAM) has been a basis model for testing technology use. Post researches of TAM have been conducted with the updating the TAM by adding new independent variables in order to increase the explanatory power of the model. However, the problem is that different independent variables have to be required to keep the explanatory power whenever adopting particular technology. This might reduce the generality of the research model. Thus in order to increase the generality of the model, this study reviewed the previous researches and collected the independent variables used, and regrouped them into three basic independent constructs. New research model was designed with three basic independent constructs with three constructs selected for the involuntary information technology usage environment. Finally, this study concluded that new technology acceptance model could be used to explain the use of new technology without any adding new particular independent variables.

Purpose: This study aims to analyze the trends of the gerontological nursing researches in Korea and suggest the direction for research in this nation. Method: A total of 241 dissertations and other published articles in Korea from 1997 to 2003 were analyzed in this study focusing on the design of the research, key words, measurement tools for basic concepts, and the intervention outcomes in the case of the experimental research. Result: Of those analyzed researches. it was found that 80.9% accounted for the published articles and 19.1% dissertations. There were no clear criteria for the classification of the old men. The most popular research design was an exploratory/descriptive study (54.4%). The major concepts were about 'physical and mental health'. Most of the measurement tools used were developed by foreigners. which were translated into Korean. Among 56 experimental studies, nursing intervention programs in 22 studies were based on physical exercise programs. Conclusion: It is necessary to analyze the trend of gerontological health research in comparison with multidisciplinary researches for elderly people. In addition, the experimental researches for both development and verification of nursing intervention programs are needed. Also, accumulation of research outcomes and development of a standardized instrument for the measurement of Korean elderly people are required.

Purpose: The objective of this study is to analyze systematically the trends of experimental researches in the area of community health nursing. Methods: This is a study based on literature review, which analyzed 137 experimental research papers in the Journal of Korean Academy of Community Health Nursing, from the first issue in 1989 to those in 2012. Results: 1) The proportion of experimental researches in the total published papers was 14.9%. 2) The mainly used research method was quasi-experiment, which was 60.6% of them, and there was no RCT. 3) Convenient sampling was used in 95.6% of the researches. 4) Only 5.1% were reviewed for keeping the ethical standards for the study objects by the IRB. 5 When classified by the Omaha Classification System, psycho-social researches were most frequent, which were followed by physiological, health-related behavioral, and environmental ones in order of frequency. Conclusion: This study found that the proportion of experimental research papers was increasing in the 2000s and ethical standards were required more rigorously. However, it was suggested that the research design be more elaborated and sampling methods be manifested to reduce research bias and errors.

As one project of 'the major state basic research program (973)' in energy domain, which is sponsored by the China Ministry of Science and Technology (MOST), a five years program of basic research for ADS physics and related technology has been launched since 2000 and passed national review last month. CIAE (China Institute of Atomic Energy), IHEP (Institute of High Energy Physics), PKU-IHIP (Institute of Heavy Ion Physics in Peking University) and other institutions are jointly carrying on the research. The research activities are focused on HPPA physics and technology, reactor physics of external source driven sub-critical assembly, nuclear data base and material study. For HPPA, a high current injector consisting of an ECR ion source, LEBT and a RFQ accelerating structure of 3.5MeV has been built. In reactor physics study, a series of neutron multiplication experimental study has been carried out and is being carrying on. The VENUS facility has been constructed as the basic experimental platform for the neutronics study in ADS blanket. It's a zero power sub-critical neutron multiplying assembly driven by external neutron produced by a pulsed neutron generator. The theoretical, experimental and simulation study on nuclear data, material properties and nuclear fuel circulation related to ADS is carrying on to provide the database for ADS system analysis. The main results on ADS related researches will be reported.
