It is revealed that there are more registered disabled people in our country who have their disability because of acquired factors such as accidents than because of innate deformity. This phenomenon will continue and the incidence of acquired disability will increase more and more. Even though there is noticeable change, the social recognition toward the disabled is still negative. Particularly, university students are in the early adulthood according to the development of life-cycle, and this is the period that people have diverse social relationships, depart from unified frame and work in various fields, and set up their own thoughts and ideology with knowledge and skills acquired from university education. Therefore, in this study, we are going to search the recognition of the university students, who are in the previous period of entering into the society, toward the disabled, and if they have negative prejudice or attitude against the disabled, we are going to find the ways to improve on their awareness positively. The subjects of the survey were randomly selected among 230 out of total 250 students by visiting thirteen universities in Chungcheong Province, and were analyzed by using SPSS (ver. 18.0) program. T-test and One-way ANOVA were used as analytical methods to look into the difference of analysis of frequency, descriptive statistic, reliability analysis and attitudes for comprehending sociodemographic characteristics of the subjects of the survey. In conclusion, it has to be not a temporary or event-like training, but a training that makes people have positive recognition and attitude towards accurate information, knowledge, human rights, disability, and diversity. This thesis has a limitation to be generalized to the university students all over the country since the region is limited to a certain area.

The purpose of this study was to identify the variables that influence the intention of students to continue participating in SW education. Based on the TAM and reference to existing research on IT introduction, subjective norms, activity promotion conditions, programming related self-efficacy, perceived easy of use, and perceived usefulness were set as factors. We also tried to identify the structural causality between these factors and the intention to continue learning. The samples of this study were 204 elementary students participating in SW education. We collected our data by conducting web survey with these students for 1 month. Among the eight hypotheses set out in this study, the two hypotheses 'subjective norms will have a positive (+) effect on perceived ease of use' and 'perceived ease of use will have a positive (+) effect on Learning continuation intention' were rejected. The characteristics of the results are as follows. First, perceived ease of use indirectly influences learning intention through mediation of perceived usefulness. Second, in order to increase the intention of continuing learning, programming self-efficacy proved to be the most significant factor. The results of this study suggest that the usefulness of SW education and the programming self-efficacy of students should be improved for effective support of elementary school students' SW education.

The purpose of this study was to investigate the effect of the outplacement service on the career decision-making self-efficacy of discharged soldiers after mid- to long-term service. The survey carried out for this research was on 557 male discharged solders living in the Seoul, Incheon, and Gyeonggi areas. The information was processed using frequency analysis, factor analysis, reliability measurement, independent sample t-test, one-way ANOVA analysis, correlation analysis, and multiple regression analysis by means of the SPSSWIN 22.0 program. The results of this study suggest that counseling, education and training affect only some sub-factors of the career decision self-efficacy. Administrative support positively affects the job information collection skill, goal setting skill, planning skill, and problem solving skill among the sub-factors of the career decision self-efficacy. Job activities support had no effect on the career decision self-efficacy.

As a population of leisure activities grows and diversifies, there is a great demand for portable and environment-friendly power generation systems. A small wind power generation system is emerging as a suitable power generation equipment to meet these needs. The most important thing when developing a small portable wind turbine is to reduce the weight of the generator and increase the efficiency. The existing 300W wind turbine generator weighs about 10kg, which is heavy to carry. Therefore, a new generator weighing less than 4kg to make it easy to carry with high efficiency has been developed. In addition, considering complicated characteristics of wind volume and topography of Korea, a small wind turbine that can be used in urban and rural areas individually was constructed. Through basic designing and optimization, the lightweight and efficient generator was manufactured. It is a 300W wind turbine designed and fabricated with reduced weight as a prototype. The average output voltage of the generator was 24.7V at 900rpm no-load test. On a load test with the average line voltage 36.8V and the average phase current 2.62A, when the mechanical input was 339.84W, an average voltage output of the generator was measured as 289.5W with efficiency of 85.18%. The generator weight was 3.84kg.

This study analyzed the public preference and acceptance regarding renewable energy projects through Choice Based Conjoint Analysis. The results show that the surveyed respondents consider the leading authority of the projects, as the most important factor when considering participating in renewable energy initiatives. Following this, the mode of participation and profit distribution and the power plant location are also viewed as important, whereas participation through decision making regarding the projects was less important. Also when participating in renewable energy projects, respondents tend to prefer to financially participating through loans or owning shares rather than volunteering support for the business such as sharing information, stating one's views, or providing cooperation and coordination. Therefore, the focus is on distributional justice, such as financial investment and profit distribution, rather than procedural justice, for instance decision making. When analyzing the part-worths utilities for the participation attribute, the respondents most preferred to receiving dividends based on earnings by owning shares with the local government in charge of the entire projects. As a consequence, the results suggest that it is important to have local government get involved and have trust-worthy governing systems in place for the initiation of the public participating-renewable energy projects.

This study examined the effects of social support and life satisfaction on the sustainability of meditation psychological counselors. The subjects were 124 meditation psychological counselors at K city. As an analysis method, frequency, reliability, and correlation analysis were performed using the SPSS 22.0 program, and multiple regression analysis on the causal relationship between variables was conducted. First, information support, a sub-factor of social support, significantly affected sustainability. On the other hand, emotional, material, and evaluation support did not affect sustainability. Second, in the effect of life satisfaction of meditation psychological counselors on sustainability, the overall satisfaction factor, which is a sub-factor of life satisfaction, positively affected sustainability. This means that the higher the information support factor of social support and the overall satisfaction of life satisfaction perceived by the meditation psychological counselor, the higher the sustainability. This study implies that the meditation psychological counselors as human factors will become more important to future society. Quality and role will be more prominent to enhance healthy continuous activities and sustainability. This study provides basic data to improve the sustainability of meditation psychological counselors.

Drone can be controlled by the method such as Bluetooth communication for close distance and can be controlled through network communication for long distance. Especially, the coordinate is set using GPS and drone is controlled using network communication and video communication when the activity range is long distance. However, the drone should be controlled by receiving control authority accordingly in response about it appropriately when the drone leaves the control area after arriving at the destination if there is a problem with network communication and video communication. So, this study proposes a method to control a drone with a simple mutually promised simple gesture and the drone can be controlled in the proposed method even if the drone leaves from the control authority in above situation. The reference posture was established for mutually promised simple gesture algorithm and automatically handed over the control authority of drone to a person who takes the reference posture when the drone recognizes it to implement this. And all the movements of the drone could be controlled by starting the beginning of all commands from the reference posture (The hovering posture of the drone). Lastly, the control authority of the drone should be returned after achieving the purpose, and the algorithm was implemented to make the drone can perform next action of its own, and it was confirmed that the drone was operating normally by the mapped instruction.

Recently, a variety of cultural life using drones as an entertainment tool has been created, and in order to realize this, more and more users are using drones with good performance enough to invade the no-flight zone. Drones for satisfying entertainment activities must have long flight times and be able to fly long distances, which can often cause great damage by invading no-flight zones or causing unwanted flight crashes. In this study, in order to solve this problem, a no-flight zone is set with GCS(Ground Control System), and when flying at a critical speed of 10km/h or less, the drone is safely operated by not entering the critical distance 10m away from the no-flight zone, and the critical speed A method was proposed to prevent the drone from entering the no-flight zone by allowing the drone to self-drop by GCS control when it flies beyond the threshold and enters the critical distance. As a result of a total of 44 repeated experiments in a specific experimental area with the proposed method, the drone safely self-dropped except for the case where it crossed the restricted area once or twice. It was found to be an appropriate way to prevent this.

After the recent COVID-19 outbreak, more and more people are paying attention to health care. Many people feel uncomfortable in life due to muscle pain after sports or exercise as a hobby and often take a break from exercise. After exercising for a long time or exercising excessively, pain appears throughout the body within 24 to 48 hours after exercise. This pain is called delayed onset muscle soreness (DOMS). In this study, the effectiveness of the pain relief of delayed onset myalgia was verified by using a high-frequency pain therapy device that generates deep heat. EMG was measured before and after pain treatment at ordinary times, RMS values were obtained through analysis, statistical analysis was performed using the SPSS program, and it was judged to be statistically significant. In addition, statistical analysis of the RMS value between normal and after pain treatment was conducted to confirm that there was no significance, and to confirm how much it returned to normal after pain treatment. In addition, since the standards for pain are different for each person even if the size of the same pain is the same, the NRS questionnaire for the size of pain was conducted, and the size of pain felt by the subjects was analyzed using the SPSS program and statistical significance was obtained. Therefore, as a result of this study, the high-frequency pain therapy device generated deep heat in the pain area to raise the temperature, and expanded the arteries and capillaries to increase blood flow, thereby increasing blood circulation and metabolism, and alleviating the pain of delayed onset muscle pain.

ESG management means to thoroughly consider the investor's perspective when evaluating corporate value, and environmental, social, and governance issues are continuous and strategic monitoring issues in identifying risk and opportunity factors related to corporate management activities. In other words, the perspective of value creation is reflected in business relationships. The fundamental purpose of ESG management is continuous business value creation and thorough management of investment risks and business transactions in contractual relationships. It is also a requirement of linked investors. The field that Korean companies are currently experiencing the most is the recognition that 'ESG information collection is necessary and maintenance must be prioritized' in investor IR and global sales and marketing departments, and the primary need for this is emerging. In addition, as the legal affairs office, environmental safety department, and human resources department, which conduct compliance management, carry out related tasks, clarity at the organizational level must precede in order to properly establish an information integration and management system. It covers the scope of securing new market opportunities such as management, disclosure and communication. Therefore, in regard to the newly emerging ESG management and response methods, it is necessary to review and implement it repeatedly so that sustainable exchange profits can be created by simultaneously managing non-financial risks as well as efforts to enhance corporate value for financial returns.
