By analyzing the current status and type of industrial safety accidents caused by industrial machinery, this study aims to examine the importance and necessity of the safety devices that are installed on-site. Additionally, this study aims to determine the implications for Korea by analyzing the status of industrial accidents in major countries and the responses to the accidents. We found that workers could easily access and operate the safety devices and that productivity and convenience were more important than safety. Thus, safety devices need to be mandatorily installed on-site for the safety of workers, and only management supervisors should be given the authority to operate them to afford a sense of safety responsibility to the workers.

Park et al. introduced the concept of generalized intuitionistic fuzzy soft sets, which can be seen as an effective mathematical tool to deal with uncertainties. In this paper, we introduce new operations such as restricted union and restricted intersection and study their basic properties, and deal with the algebraic structure of generalized intuitionistic fuzzy soft sets. The lattice structures of generalized intuitionistic fuzzy soft sets are constructed.

The purpose of this study is to explore the necessity and possibility of establishing a research institute for local educational autonomy where the importance and necessity of institution establishment and operation are increasing with the decentralization and educational autonomy. The necessity of establishing a local educational autonomous research institute was examined in terms of both external and internal necessities, and the possibility of establishment in terms of the form of establishment, financial resources, and legal basis. In order to effectively cope with common issues by leading the nation's educational autonomy policy and legal agenda, and to support regional policy research and development by linking and cooperating with regional educational policy research institutes, local educational autonomous research institutes are established. This is an urgent point. Considering the publicity, professionalism, economic feasibility, and stability of specialized research institutes, the form of foundation corporation seems to be appropriate, and, like the case of specialized research institutes in general local autonomy, legal grounds for the establishment of special law should be prepared. In the future, it is necessary to conduct collaborative discussions and academic discussions with the Ministry of Education and the National Council for Superintendents of Education.

This study evaluated economic value recognized by the residents for the pleasant urban park management using contingent valuation method(CVM) to APEC Memorial Park in Pusan in terms of private fund development for the management of the city park. As a result, the estimated amount payable by each household for the management of APEC Memorial Park in Busan was between 5,673 won and 8,358 won. If such amount is expanded to households in park hosting area, it was 2.2~2.3 times of the park management budget in 2012, which demonstrates the willingness to pay (WTP) of residents for pleasant park was higher than the management budget. Social factors of respondents affecting WTP for city park management operation included age, educational level and income level. Those with high age and high education level had higher WTP. And, WTP was much affected by the use of park and recognition of residents. In particular, those with high frequency in the use of parks had higher WTP, and the users with more than once per week had 1.1 times higher WTP than overall WTP. Then, the satisfaction of park rather than recognition of necessity of park had led to higher WTP. Accordingly, it is necessary to manage park facility management and use program operation to enhance park satisfaction and it is also required to develop a park culture distribution policy to link such recognition to donation.

Purpose: This study sought to investigate the perceptions and service needs of tele-physical therapy among people in their 50s and older in Korea. Methods: Subjects were inducted during a 14-day survey of 104 people over the age of 50 in Korea and were administered a questionnaire consisting of 14 questions about their general characteristics and another 14 questions about tele-physical therapy. Results: The general characteristics of the participants (participants' gender, whether they were single or married, number of cohabiting families, final education, major, job, physical therapy experience, tele-physical therapy experience, presence of a physical therapy worker among relatives, subjective health awareness, chronic disease conditions if any, frequency of drinking, and smoking) were investigated. Among the perceptions of the subjects about tele-physical therapy, the score of 'awareness' was the lowest, and that of 'resolving restrictions on hospital visits' was the highest. In an analysis of the correlation between perceptions and needs, there was a significant correlation with factors other than 'awareness' and 'information protection' factors. The regression analysis of necessity and factors revealed that the awareness of necessity increased as the intention to use, health improvement, and time efficiency improved. Conclusion: These findings presented the perception and necessity of tele-physical therapy for adults in their 50s or older in Korea. These results will help confirm the demand for tele-physical therapy in this age group in Korea and the need to improve the available physical therapy services.

Purpose: The purpose of this study was to identify occurrence of needle stick and sharp injuries(NSI) among students, level of faculty stress, and necessity of informed consent when students practice injection skills in fundamentals of nursing practice (FNP). Methods: Data were collected using self-reporting questionnaires and 74 faculty members who teach FNP responded it. Questionnaires included general characteristics, experiences of NSI, stress level, and informed consent. Data were analyzed using frequency, percent and paired t-test. Results: Of 74 faculty members, 51.4% experienced NSI 3~4 times or more during their FNP classes. Major procedures causing NSI during FNP were 'breaking the neck of ampules', 'disposing of used items', and 'inserting needles'. The stress level of faculty was higher and more than doubled when training with human beings compared to manikins. Most faculties (86.5%) agreed to the necessity of informed consent so that the safety of faculty and students could be protected and to provide enough information even though only 10.8% of faculty in this study got informed consent. Conclusion: Because there is high risk in every procedure of NSI, faculty has a high level of stress during injection practice in FNS. Therefore, it is necessary to develop a standard NSI precaution program for junior nursing students and discuss informed consent.
