Recently, as voluntary activity has become more widespread, there have been some voluntary activity movements in the provision of library services for people with disabilities. This study aimed to develop a model on voluntary activity in library services for disabled people in public libraries. Survey data collected through three data collection methods showed that volunteer activities in public library services for the disabled were very poor, and recommended the training of library staff and volunteers serving disabled people, the management of educational programs for librarians about the disabled and the dissemination of standardized manuals. From the results of the survey, a voluntary activity model, based on three factors, the aims of library services, the types of the disabilities, and volunteer services including specific sub areas of services, was developed. Finally, this voluntary activity model will contribute to the theory development of library services for the disabled

One of the major applications of CRM systems is to integrate and automate selling processes. CRM systems provide sales people with tools and data sources they need to reengineer their selling processes. In the industry where sales are traditionally based on personal relationships and the use of the CRM systems is voluntary, the installation of technical solutions does not guarantee Selling Process Reengineering (SPR). The objective of this study is to investigate (1) organizational factors that influence CRM use by sales personnel; and (2) the mediation effect of CRM system use on SPR success when system use and process reengineering are voluntary rather than institutional. Understanding the determinants of voluntary CRM system use and SPR success provide valuable guidance for managers. Managers can benefit from this study by focusing on improving the factors that affect voluntary CRM system use and SPR success.

The purpose of this study is to investigate the effect of balloon blowing exercise on multiple pulmonary function and maximum voluntary ventilation in patients with mild intellectual disabilities in their 20s. 10 people in the experimental group and 10 people in the control group participated in the experiment. The experimental group performed the balloon blowing exercise for 30 minutes a day, and the control group performed the diaphragm breathing exercise for 30 minutes each. The subjects measured voluntary capacity and maximal voluntary ventilation using Fitmate before and after the experiment. Subjects were assessed with Vital capacity(VC) and Maximal voluntary ventilation(MVV) before and after the test and the results were compared with the paired t test. Data analysis was performed with SPSS win 18.0. After the experiment, the experimental group showed higher lung capacity and maximum ventilation than the control group. Through this study, the experimental group increased voluntary capacity and maximum voluntary ventilation more than the control group. It is thought that the quality of life can be improved if we continuously manage the health of intellectuals by developing various breathing exercise programs.

This study presents the achievements and limitations of the voluntary-based Total Maximum Daily Load (TMDL) through statistical analysis of water quality monitoring data and performance assessments of TMDL plans implemented in the Gyeongan watershed. The results clearly showed that responsible local governments complied the allocated TMDL and the designated water quality goals were successfully achieved in the required period. This was possible because the Ministry of Environment provided innovative incentives, such as, relaxations of the existing tight land-use regulations and full-scale financial aids for constructing and operating public treatment facilities to draw local government voluntary participation. However, a couple of problems which decreased the effectiveness and efficiency of the voluntary TMDL were identified. The different TMDL implementation schedules between upstream (Yongin) and downstream (Gwangju) governments caused delay in water quality improvement and exaggerated TMDL allocation to the local development which made excessive investment in the treatment facilities. Although it is not directly related to the voluntary scheme, technical methods for establishing and assessing the water quality goals should be improved so that the effects of flow conditions on water quality are properly assessed. We expect that results of this case study contribute to developing a more effective voluntary-based scheme for the implementation of the so-called 'tributary TMDL' in the future.

Objective: The purpose of this study is to identify the mechanism of changes in maximum voluntary torque with the magnitude and duration of pre-activation torque during voluntary isometric knee extension. Method: 11 male subjects (age: 25.91±2.43 yrs., height: 173.12±3.51 cm, weight: 76.45±7.74 kg) participated in this study. The subjects were required to produce maximal voluntary isometric torque with a particular pre-activation torque condition. The properties of pre-activation torque consisted of the combinations of 1) three levels of magnitude, e.g., 32 Nm, 64 Nm, 96 Nm, and 2) two levels of duration, e.g., 1 sec, and 3 sec; thus, a total of six conditions were given to the subjects. The force and EMG data were measured using the force transducers and wireless EMG sensor, respectively. Results: The results showed that the maximum voluntary torque increased the most with relatively large and fast (96 Nm, 1 sec) pre-activation condition. Similarly, with relatively large and fast (96 Nm, 1 sec) preactivation, it was found that the integrated EMG (iEMG) of the agonist muscles increased, while no significant changes in the co-contraction of the antagonist muscles for the knee extension. Also, the effect of pre-activation conditions on the rate of torque development was not statistically significant. Conclusion: The current findings suggest that relatively larger in magnitude and shorter in duration as the properties of pre-activation lead to a larger magnitude of maximal voluntary torque, possibly due to the increased activity of the agonist muscles during knee extension.

E-learning becomes an important part of education these days in Korea. Students had no choice but to accept the e-learning when the e-learning was used as a supplementary learning tool within a traditional class or a stand-alone distance education. This study focuses on the students' intention of e-learning acceptance for voluntary studies. In voluntary study, students have the rights to adopt the e-learning or not for their personal study. We used individual characteristics as the external variables of TAM to explain user acceptance of e-learning for voluntary studies and examined the effect of individual characteristics on user's beliefs. Research model and nine hypotheses were set up to identify the relationships among these variables based on investigations of previous researches. The theoretical model is tested with questionnaires from 420 users who accept e-learning for voluntary studies. We tested the measurement and research models by applying a structural equation modeling(SEM) approach, using the AMOS 5.0. Overall, the results provided support for the model as explaining acceptance of an e-learning system. Most path coefficients in the research model were found statistically significant. The results showed usefulness and enjoyment and subject norm were the factors affecting attitude of students using e-learning. In addition, usefulness and subject norm were the factors affecting intention of students using e-learning. The results show innovation and self-efficacy have a significant impact on user's perception of ease of use. Self-efficacy also have significant effects on user's perception of usefulness.

The purpose of this study is to empirically examine organizational change for a technological application of the fourth industrial revolution. The theoretical background of this study utilized organizational change management, the fourth industrial revolution, technological innovation, and voluntary acceptance. This research method used structural equations, cluster analysis, and analysis of variance. According to the results of the study, the organizational implement system, organizational leadership, and organizational operating system provided a positive effect on the voluntary technology acceptance of organization members. The voluntary technology acceptance provided a positive effect on the effectiveness of individual task innovation. However, organizational institutionalization among the independent variables did not affect voluntary acceptance. All independent variables except the organizational institutionalization had a partial mediating effect in the mediating effect verification. Meanwhile, The three groups by the cluster analysis were classified as new technology apathy, preference, and anxiety groups, and differences appeared among groups in the importance of organizational change variables. The organizational implement system in the technology apathy group and the organizational operating system in the technology anxiety group have a positive effect on voluntary technology acceptance. The technology preference group shows that a positive effect on organizational leadership and a negative effect on organizational institutionalization for voluntary technology acceptance. This study analyzed the technology application of the fourth industrial revolution in the organization based on the theory of organizational change. There has been reexamined the organizational change theory based on the new technology acceptance by the change of external environment in the fourth industrial revolution and the importance of technology innovation. As a practical implication, firms that are interested in a new technology of the fourth industrial revolution should prioritize preparing an implementation system when designing organizational changes.

Considering the role of a financial analyst that directly affects investors as an information mediator, management's decision to disclose to maximize corporate value will have an important impact on investors as well. On the other hand, whether or not managers vary the level of disclosure depending on the corporate form will have great implications for policy authorities. However, there is no domestic research on the relationship between the corporate form and the quality of voluntary disclosure. Our study shows that the corporate form tends to deepen the negative relationship between the proprietary information cost and the quality of disclosure. Examining whether the relationship between proprietary information cost and management disclosure decision making is valid for domestic companies is expected to provide meaningful implications for investors and regulators. Depending on the corporate form, if an entity makes a discriminatory disclosure, the cost of capital will be affected. A more in-depth follow-up study on this should be done.

As all flight training institutions in Korea were approved by the Ministry of Land, Infrastructure and Transport (MOLIT) as aviation training organizations (ATO), safety management based on the Aviation Safety Management System (SMS) became mandatory. However, even though safety management using SMS has become mandatory, the performance of aviation safety voluntary report, which is the core of the system, remains low compared to other countries. The current address of SMS, a ATO, is like a watermill without water. The present study is to find out why voluntary aviation safety reports, which is equivalent to water from waterwheel, is underperforming and to suggest ways to revitalize it.
