  • Many cellular phone volunteer studies have been conducted since such a social issue is raised that the long time usage of cellular phone by teenagers may increase health risk. While there were various adult volunteer studies using GSM cellular phone on heart rate and blood pressure, very few teenager studies using CDMA phone were conducted. In this study, two volunteer groups of 21 teenagers and 21 adults were exposed to 300 mW CDMA wave for half an hour, and the physiological parameters such as blood pressure, heart rate, respiration rate, and skin impedance were investigated. All the parameters fur both groups were unaffected during exposure except the skin impedance of teenager group.

  • This study was performed to discuss how to develop policies to support social participation by full-time housewives, from the perspectives of human resource development and utilization. This study focused on three areas of potential human resource development: (a) labor force participation (b) social education (c) volunteerism. It analyzed the related "social infrastructures," especially labor market situation and child care systems. The current governmental policies and other social programs implemented by various institutions as well as the relevant literatures were reviewed. The preliminary policy proposals outlined in this study were evaluated by the policy developers and experts through several hearings and discussions. Programs proposed from this study were as follows : (a) programs to support housewives who wish to find employment or create a self-owned business, (b) educational programs exclusively offered for full time housewives, and (c) programs to award certificates and rewards and to create paid employment tied to volunteer work. In addition, the ways how to ameliorate the gender discrimination by changing the labor and social environments and institutionalizing the child care were discussed.

Subjects in this study were 245 Health Centers all chosen. Data were collected from April. 12. 1999 to May. 31. 1999. and the data for analyses were ones of 116 respondents. Then. the data coded and submitted to Fisher's exact test. NPAR1WAY ANOVA, Correlation analysis. multiple regression analysis, multiple logistic regression analysis with SAS program. The key results from this study can be epitomized as follows: 1. 43.1% of responding health centers answered that they 'utilize volunteers'. The average number of volunteers who were engaged in responding health centers was 43, out of which 7 were men and 36 were women. As for the adequacy of the number of the volunteers. 55.1% responded 'not enough' and 30.6% responded 'adequate'. The more the number of volunteers needed. the more the number of utilizing volunteers is. When asked about their views concerning the utilization of volunteers in Health Centers. 88.7% of all respondents answered in the affirmative. The accountable factor for the utilization of volunteers was the present utilization of volunteers. 2. Concerning the reasons for using volunteers. 'to induce local people's participation in health services' was the highest comprising 76% of the responding health centers. 3. Most of volunteers were housewives and independent enterprisers. The most type of volunteer activities was 'just simple labor'. 4. As for the action duration of volunteers. 69.4% answered 'under 6 months'. The factor was significant difference with the action duration of volunteers was 'to provide social meeting' in the middle of rewards for volunteers. 5. Asked about the problem in utilizing volunteers. 53.2% answered 'the difficulty of recruitment and education for volunteers'. and 42.6% answered 'lack of budget and manpower needed for the utilization of volunteers.' 6. Concerning the evaluation of the performance by volunteers. 88% answered 'satisfactory'. With regards to the reason for that. 29.3% answered 'volunteers can provide various kinds of services' 7. 88.7% of responding health centers answered that they will continuously or newly utilize volunteers in the future. 8. The main health program services which expect utilization of volunteers were visiting health services(63.2%). old people's health services (25.3%). These were not significant difference with any explanatory variable. 9. The average number of volunteer needed in responding health centers was 38. The more the average number of utilizing volunteers. the more the number of volunteers needed is. The more the degree of financial independence. the more the number of volunteers needed is. In conclusions. Health centers are necessary to promote their role of recruitment. education and training for volunteers. the development of volunteer activities programs.

  • Magnetocardiogram (MCG) topography is a useful diagnostic technique that employs multi-channel magnetocardiograms. Measurement of artifact-free MCG signals is essenctial to obtain MCG topography or map for a diagnosis of human heart. Principal component analysis (PCA) combined with an artificial neural network (ANN) is proposed to remove a pulse-type artifact in the MCG signals. The algorithm is composed of a PCA module which decomposes the obtained signal into its principal components, followed by an ANN module for the classification of the components automatically. In the experiments with volunteer subjects, 97% of the decisions that were made by the ANN were identical to those by the human experts. Using the proposed technique, the MCG topography was successfully obtained without the artifact.

  • A numerical human head/neck model was constructed for analyzing the implication in decleration injuries. This model consists of nine rigid bodies representing the head, cervical vertebrae C1-C7, and T1. These rigid bodies were connected by intervertebral disks described by massless beam elements. Muscles and ligaments were also incoperated in the model represented by nonlinear spring and viscoblastic element respectively Agreement of the analytical kinematic response with the results of experimental data from a volunteer run was satisfactory. Moreover, possible injury estimation from the calculated moment, force variations in the disc, and force variation in ligaments matched well with clinical observations.

  • The simultaneous determination of As(III), As(V), and DMA has been performed by ion chromatography (IC) coupled with inductively coupled plasma-mass spectrometry (ICP-MS). The separation of the three arsenic species was achieved by an anionic separator column (AS 7) with an isocratic elution system. The separated species were directly detected by ICP-MS as an element-selective detection method. The IC-ICP-MS technique was applied for the determination of arsenic species in a NIST SRM 1643d water sample. An As(III) only was detected in the sample. The detection limits of As(III), As(V) and DMA were 0.31, 0.45, and 2.09 ng/mL, respectively. It was also applied for the determination of arsenic species in a human urine obtained by a volunteer, and three arsenic species were identified. The determination of total As in human urines that were obtained from 25 volunteers at the different age was also carried out by ICP-MS.

  • In this study, we suggested a data structure for the management of human libraries based on the analysis of the significant components for systematically managing and operating the human library service. At first, we proposed the components of human library metadata set which are 'Human Resource', 'Human Resource', 'Librarian', 'Volunteer', and 'User'. And this study verified the meta concepts of metadata set such as 'Human Library', 'Human Book' and 'User', developed the metadata set for human library using the meta concepts. To check the validity of the metadata set and to improve its usability, we created and published a XML document including the metadata structure and link between the meta concepts. In conclusion, this study provided the possibility that the library could develop the service recommended human book to user through user profile.
