Voluntarism as an ethics standard for the human race in the 21st Century, suggest to us partical and realistic measures as well as an ideological framework which can solve the problems in the national area. Volunteer activities in the society by university and university students are very important within the nation, provincial communities as well as in the country area. This study focuses on voluntary activities of university students of all the local university on gyungsang buk do after looking in to the present situation of voluntarism and issues and seeks to search into the policy issues that university students voluntary activities should be directed towards. For the active execution of college students voluntary activities, it is necessary to establish partnerships between local communities and university, policy support from the university authorities, program development and expansion of the boundaries of volunteer avtivities, and connections between university Health voluntary health center.

This investigation & study has been made in oder to revitalilize the health care for the elderly in public health centers. The date subject, including 88 persons in charge health services in public heal centers, were from Chejudo. These were largely female, the average age was 38.4 at the health center. Their responsibilities included home visitation, nutrition management for the early, health education, and physical therapy. The most important problem were personal management and a lack of facilities, especially in home visitation, health education, physical therapy. Systematic networks of various activities are needed to encourage not only the patient but also volunteer who will also take part in these services. The numbers of members in charge of the elderly are not only to be increased and educate with facilities and equipment but also better provided with proper facilities and equipment. This is the best way to conduct health services the elderly.

This paper presents the results of an integrated navigation performance analysis for selecting the sensor of an unmanned underwater vehicle (UUV) using Monte Carlo numerical simulation. An inertial measurement unit (IMU) and Doppler velocity log (DVL) are considered to build the integrated navigation system. The position error and price of the sensor are selected as performance indices to evaluate the volunteer integrated navigation systems. Monte-Carlo simulation is introduced to analyze the circular error probability (CEP) and its variance. Simulation results provide the proper sensor combination for integrated navigation in relation to the performance and price.

The experimental results of visual stimulation with the tailored RF pulse are reported. Tailored RF pulse is used for the susceptibility effect imaging. Around 25% signal change of visual cortex area is detected during photic stimulation. Interestingly, with the tailored RF pulse, the signal intensity of visual cortex is deceased during photic stimulation. It is, however, increased with normal $T_2$ weighted imaging. The comparison between normal $T_2$ weighted imaging and the tailored RF pulse imaging are performed with 4T NMR system and the results with human volunteer are also presented.

PURPOSE. The purpose of this in vitro study was to assess whether scanning strategies of virtual interocclusal record (VIR) affect the accuracy of VIR during intraoral scanning. MATERIALS AND METHODS. Five pairs of reference cubes were added to the digital upper and lower dentitions of a volunteer, which were printed into resin casts. Subsequently, the resin casts were articulated in the maximal intercuspal position in a mechanical articulator and scanned with an industrial computed tomography system, of which the VIR was served as a reference VIR. The investigated VIR of the upper and lower jaws of the resin master cast were recorded with an intraoral scanner according to 9 designed scanning strategies. Then, the deviation between the investigated VIRs and reference VIR were analyzed, which were measured by the deviation of the distances of six selected reference points on the upper reference cubes in each digital cast to the XY-plane between the investigated VIRs and reference VIR. RESULTS. For the deviation in the right posterior dentitions, RP group (only scanning of right posterior dentitions) showed the smallest deviation. Besides, BP group (scanning of bilateral posterior dentitions) showed the smallest deviation in the left posterior dentitions. Moreover, LP group (scanning of left posterior dentitions) showed the smallest deviation in the anterior dentitions. For the deviation of full dental arches, BP group showed the smallest deviation. CONCLUSION. Different scanning strategies of VIR can influence the accuracy of alignment of virtual dental casts. Appropriate scanning strategies of VIR should be selected for different regions of interest and edentulous situations.

This study aims to verify the effects of the life redesign educational program based on the baby boomer (11 members of experimental group, 12 members of control group). The program was conducted for two hours two times in a week in the area of Chungnam (Total 8weeks 16sessions). First, in the result of the Wilcoxon's pairs signed-ranks test between the pre-post tests for the analysis on the program effectiveness of the experimental group of baby boomer, the baby boomer of experimental group showed an improved perception of preparing the volunteer work in the perception of preparing their old age, and there was no pre-post significant differences in the control group. In case of the experimental group, perception of the post-retirement preparation, such as a physical preparation, emotional preparation, financial preparation, volunteer work preparation and leisure activities preparation increased in average. Second, the satisfaction for the program's educational process, educational contents, educational data, educational method, instructor and the educational environment were shown to be more than 3.5 points out of 5 points in full.

Objective: To develop a population pharmacokinetics (PK)/pharmacodynamics (PD) model for alcohol in healthy volunteers and to elucidate individual characteristics to affects alcohol's PK or PD including dissolved oxygen. Methods: Following multiple intakes of total 540 mL alcohol (19.42 v/v%) to healthy volunteer, blood alcohol concentration was measured using a Breathe alcohol analyser (Lion SD-400 $Alcolmeter^{(R)}$). A sequential population PK/PD modeling was performed using NONMEM (ver 7.3). Results: Eighteen healthy volunteer were included in the study. PK model of alcohol was well explained by one-compartment model with first-order absorption and Michaelis-Menten elimination kinetics. $K_a$, V/F, $V_{max}$, $K_m$ is $8.1hr^{-1}$, 73.7 L, 9.65 g/hr, 0.041 g/L, respectively. Covariate analysis revealed that gender significantly influenced $V_{max}$ (Male vs Female, 9.65 g/hr vs 7.38 g/hr). PD model of temporary systolic blood pressure decreasing effect of alcohol was explained by biophase model with inhibitory $E_{max}$ model. $K_{e0}$, $I_{max}$, $E_0$, $IC_{50}$ were $0.23hr^{-1}$, 44.9 mmHg, 138 mmHg, 0.693 g/L, respectively. Conclusion: Model evaluation results suggested that this PK/PD model was robust and has good precision.

Kim et al. (2006) and Kim et al. (2009) reported a set of explanatory variables affecting donation frequency when they analyzed nationwide survey data on donations collected in 2002 by Volunteer 21, a nonprofit organization in Korea. The primary purpose of this paper is to correct computational errors found in Kim et al. (2006) and Kim et al. (2009), to rectify major results in the Tables and Figures and to supplement Kim et al. (2009) by providing new results. We add two logistic regressions to the ZIP and a mixture of two Poisson regressions of Kim et al. (2009). Through these two logistic regressions we could detect a set of explanatory variables affecting donation activity (0 or 1) and another set of explanatory variables, in which the volunteer (0, 1) variable is common, discriminating the infrequent donor group from the frequent donor group.

Purpose: This descriptive research was carried out to identify how high school students' attitude to death and their meaning of life were affected by hospice volunteering and death education. Methods: This study is based on a structured questionnaire designed for 180 high school students who were given death education while doing volunteer work at non-profit hospice hospitals and another 288 high school students not doing any hospice volunteer work. The collected data was processed by the SPSS 20.0 program and then analyzed by $x^2$ test, t-test and ANOVA test. Results: High school students' attitude to death and their meaning of life showed significant differences depending on whether or not they had volunteered at hospice hospitals. The group with hospice volunteering experience tended to be more negative about death and have a higher meaning of life compared to those without hospice volunteering experience. Students with proper hospice recognition made up 52.4%, those who expressed hopes to receive hospice-care themselves if necessary accounted for 70.5%, and those who said they would like to take care of their family members either at home or at a hospice center if any of them got incurably sick comprised 59.0%. Those who thought dignified death is to be with one's family or any other meaningful person were 47.6% and 18.5% of the students thought that 'thinking they had led a meaningful life' was the core of a dignified death. Conclusion: Given the above results, it became clear that hospice volunteering and death education can affect high school students' meaning of life and their attitudes toward death.

This study was conducted to determine the effect of major-related volunteering on self-esteem and self-efficiency in fifty three university students who are majoring in occupational therapy. Students volunteered for 20 days in the geriatric service center for dementia from July 27, 2009 to August 21, 2009. Questionnaire survey was conducted to determine the difference in, self-efficiency, career awareness before and after the volunteering. Student showed satisfaction to volunteer program in general, and self-esteem and self-efficiency improved from $29.43{\pm}2.51$ point and $30.45{\pm}3.41$ point to $31.66{\pm}2.63$ point and $33.26{\pm}3.93$ point, respectively. In addition, subjects expressed comfort toward occupational therapy and were able to recognize how to prepare the role of occupational therapist after graduation. These results indicates that occupational therapy-related volunteering was effective in understanding occupational therapy and improving career awareness.
