Background: Low back pain (LBP) is a common musculoskeletal disorder worldwide, with a lifetime prevalence of up to 80%. Among nonsurgical treatments for chronic LBP, Korean medicine treatments are highly preferred, and pharmacopuncture therapy combining acupuncture and herbal medicine is widely used. However, no evidence-based study has focused on the use of various types of pharmacopuncture. Methods: The pragmatic randomized controlled clinical trial will include 44 participants; recruitment will start in July 2023. All participants will receive integrated Korean medicine treatment including acupuncture, cupping, and infrared therapy, and the intervention group will also receive pharmacopuncture. After 16 treatment sessions, twice a week for 8 weeks, follow-up assessments will be performed at week 9. As a pragmatic randomized controlled clinical protocol, the type, dose, and acupoints of acupuncture and pharmacopuncture are not determined in advance but are selected and recorded according to the clinical judgment of the Korean medicine doctor. Results: The primary outcome will be measured using a visual analog scale score, and the secondary outcomes include the Oswestry disability index, patient global impression of change, no worse than mild pain, and range of motion. Safety will be assessed by examining participants' self-reported adverse events and vital signs and conducting blood tests before and after the test. Conclusion: This study aims to provide clinical evidence of the effectiveness and safety of pharmacopuncture for chronic LBP.

Due to COVID-19, much research has been conducted on learning loss and educational gaps due to the postponement of the start of school and prolonged online distance learning, and most of the research has focused on the phenomenon of educational gaps. If a pandemic situation like this occurs in the future, fundamental policies are needed to resolve the educational gap. A fundamental solution requires not only an understanding of the educational gap phenomenon, but also the structure behind the phenomenon. Therefore, from a structuralist perspective, this study sought to model the educational gap caused by COVID-19 as a prototype of systems thinking and identify its structure. In addition, we looked at the unintended consequences resulting from policies aimed at resolving existing educational gaps. In order to respond to similar disaster situations in the future, policies for resolving the digital gap, support for basic academic skills, quality improvement for distance learning, and self-directed learning were discussed based on the structure of this study.

Gas foil thrust bearings (GFTBs) are oil-free self-acting hydrodynamic bearings that support axial loads with a low friction during airborne operation. They need solid lubricants to reduce dry-friction between the runner and top foil and minimize local wears on their surfaces during start-up and shutdown processes. In this study, we evaluate the lift-off speeds and load capacity performance of a GFTB with Polytetrafluoroethylene (PTFE) surface coating by measuring drag torques during a series of experimental tests at increasing ambient temperatures of 25, 75 and 110℃. An electric heat gun provides hot air to the test GFTB operating in the closed booth to increase the ambient temperature. Test results show that the increasing ambient temperature delays the lift-off speed and decreases the load capacity of the test GFTB. An early developed prediction tool well predicts the measured drag torques at 60 krpm. After all tests, post inspections of the surface coating of the top foil are conducted. Scanning electron microscope (SEM) images imply that abrasive wear and oxidation wear are dominant during the tests at 25℃ and 110℃, respectively. A quantitative energy dispersive spectroscopy (EDS) microanalysis reveals that the weight percentages of carbon, oxygen, and nitrogen decrease, while that of fluorine increases significantly during the highest-temperature tests. The study demonstrates that the increasing ambient temperature noticeably deteriorates the static performances and degrades the surface coating of the test GFTB.

This study was conducted to suggest a start-up policy that includes start-up education and support for active seniors with various careers who try to change their careers before and after retirement. From this point of view, this study divided the factors affecting the entrepreneurial will of active seniors into entrepreneurship organizational and functional competency and identified the effect of these competencies on entrepreneurial efficacy and entrepreneurial intention. In the proposed model, start-up competency is divided into organizational competency (leadership, creativity problem-solving, communication, decision-making) and functional competency (management strategy, marketing, business plan). And this study examined the mediating role of entrepreneurial efficacy in the relationship between entrepreneurial competency factors and entrepreneurial intention. Meanwhile, PLS-POS analysis was performed to uncover the heterogeneity and pattern in the proposed structural model. The survey was conducted with the help of an online survey company from November 27 to December 15, 2020 for the active senior age group from 40 to under 65 years old. Data were collected from a total of 433 panelists and analyzed using SPSS 22.0 and SmartPLS 3.3.7 programs. The findings are as follows. First, the finding shows that the entrepreneurial organizational and functional competencies of active seniors had significant positive(+) effects on entrepreneurial efficacy. Second, the result shows that entrepreneurial organizational and functional competencies of active seniors had significant positive(+) effects on entrepreneurial intention. Third, the findings show that entrepreneurship efficacy had a significantly positive(+) effect on entrepreneurial intention. The findings of PLS-POS show that entrepreneurship education needs to be carried out by identifying the needs that require entrepreneurial organizational and functional competency when training for entrepreneurship competency. In summary, the findings of the current study are to determine what the competency factors are for the government (local government) to increase the policy direction necessary for establishing and implementing entrepreneurship education and training programs to develop policies to enhance the economic activity participation rate of active seniors.

The unabated influx of micro businesses has turned the Korean retailing market to a rat race, which causes severe financial distress for micro business owners due to heavy competition. The woes of these micro business owner's are exacerbated by the presence of large scale distributors such as Super Supermarket(SSM) and large discount stores. In summary, the Korean retail market is overburdened an uneconomically viable. Retailing has low barriers to entry which attracts unskilled labor or those with little capital. These start-ups have low opportunity costs since they would make low wages elsewhere in the economy. Thus, these owners are content with relatively low returns on their investment. These 'subsistence ventures' are maintained for economical viability rather than economic growth. These 'subsistence ventures' intensifies competition among small-scale businesses. The presence of large retail corporations also aggravates the situation. The recent stagnation of the economy has worsened the retail market in Korea. The overwhelming competition solidifies the coarse structural system and the prolonged economic sluggishness has increased the risk of insolvency for micro business owners. As the economy continues to stagnate, the imminent risk in retailing market will rise up to surface threatening economic stability. More systematic inflows and outflows of retailers are required in order to redress this structural problem. It has been empirically shown that the self-employment rate is high in Korea compared to other OECD countries. To draw the comparison of self-employment rate by industry, Korea shows high rates among transportation, whole sale, retail, education, lodging, and restaurants. In the case of the transportation and education service sectors, this high rate can be explained by the idiosyncratic nature of Korean culture. In the transportation sector, political policies favor private cap service and private freight carriers. In the education service sector, Koreans put particular emphasis on education that leads to many private institutions that outnumber other OECD countries. For these singular reasons, Korea maintains high micro business, self-employed rates particularly in retailing. A comparable nation is Japan, with its similar social, economic, cultural environment among OECD countries. Unlike Korea, Japan has much lower rates of micro business which continues to decrease. Also Korean retailers are much more destitute than Japanese. The fundamental problem of Korean retailing is the involuntary exit of these 'subsistence ventures,' micro businesses with low margins, in which a small drop in demand can lead to financial difficulties for the owner. This problem will be exacerbated when Korean babyboomers retire and join the micro business ventures. The first priority in order to cope with the severity of oversupply in retailing is to provide better opportunities for the potential self-employers. There should be viable alternatives to subsistent ventures. Strengthening the retirement program, scrutiny of exit process, reconfiguration of policy funds are the recommendations.

After Four-Seven debate in late 16C, Korean Neo-Confucian scholars had developed their theories on human nature and morality such as Insimdosimsoel (theories on the moral emotion and desire), Inmulsoengron(theories on human nature and animal nature), Mibalsimcheron(theories on the calm mind as the embodiment of morality). Confucian scholars had been active member of society since acceptance of Neo-Confucianism. They had the plans of social reforms on the basis of moral self cultivation from the elite Confucians to commoners. So the Confucian scholar took part in the foundation of new Confucian kingdom, the Joseon Dynasty(1392). Kwon gun(1352~1409), the famous Neo-Confucian scholar wrote Iphakdosoel(pictogram for beginer of Neo-Confucianism) which emphasized the importance of moral self cultivation and that the mandate of heaven in human nature is identical with Li, the moral principle which the origin of the human intrinsic moral ability as the basis of unity with man and heaven. He thought that ethical life is identical with mandate of heaven, so he insisted all the member of society should follow Li, the moral principle which the origin of human morality and social goodness. Also he emphasized the morality was the intrinsic and most important value of human being. Therefore ethical life became essential part of self cultivation. Joeng Ji-un(1509~1561) wrote the Chunmyongdosoel (pictogram of mandate of Heaven), the start point of Four-Seven debate in mid 16C. Joeng followed Kwon's theoretical line. He emphasized the importance of moral self cultivation and the human intrinsic moral ability. He wrote that the Four moral emotions arise from Li, the moral principle of mind, while Seven emotions arise from Ki, vital force of body. He insisted that human being should control Ki, the vital force to follow the Li, the moral principle of mind. This Korean Confucian scholars developed theories of morality and self cultivation. This theories not only show the philosophical speculation of Korean Confucian scholars but also show the social idealism and moral utopianism which grounded on the human morality. So they had trust in human morality which can guide human being into the right track to the good and peaceful society. These tendencies are main characteristics of Korean Neo-Confucianism which has seen from the begining of acceptance of Neo-Confucianism. Some modern philosophical criticism which insist the Korean Neo-Confucian theories such as Four-Senven theories was indulged in academic discussion are not only neglect the historical realty but also ignore the potential of Korean Neo-Confucian heritage.

The basic purpose of this study is to examine the relationship among entrepreneurial intention, university supports for startup, and startup activities of university students. For the study, we identified the influence factors of students' startup intention based on reviewing preceding studies and examined how these factors affect their intention of new venture startup. In addition, this study attempted to examine how these factors that can have a significant impact on entrepreneurial intention affect startup activities and analyzed how entrepreneurial intention would mediate the relationship between these influence factors and startup activities. A total of 769 students who chosen by random were surveyed and all questionnaires were sent by mail to the universities that entrepreneurship education and entrepreneurial programs were selected as the forerunners from the government. As a result, this study revealed that student's psychological traits such as entrepreneurial self-efficacy and risk-taking have significant effect on the intention of startup. And student's exposure to the role models and various entrepreneurial experiences such as entrepreneurship education and entrepreneurial student's club in the university has significantly positive influence on the intention of startup. This study also found that the effects of these explanatory variables of this research on startup activities have been partially mediated by entrepreneurial intention. The entrepreneurial intention was also proven to have a significant effect on startup activities. Finally, the extent to which university supports activities for students' startup moderated the relationship between entrepreneurial intention and university students' startup activities. We believe that these results of this study contribute to the understanding of the entrepreneurship process both theoretical and practical perspectives.

This paper aims to identify determinants of entrepreneurial intentions among college students of a university in Daejeon. We have used a revised Entrepreneurial Intention Questionnaire including personal traits, demographic characteristics, the three factors of the Theory of Planned Behavior (TPB), motivations to startup and planned startup time, and entrepreneurial intentions. The analysis shows that there are strongly significant and positive relationships between the three TPB factors and entrepreneurial intentions of college students. In addition, students' motivations to create a firm such as independence and self-achievement have a positive and significant effect on their entrepreneurial intentions, while the students who want to start their business right after their graduation have significantly higher entrepreneurial intentions than those who want to create a firm after doing a salaried job. Furthermore, students whose parents have created or operated a firm have no significant difference from others, and parents' startup business type are significantly different from their sons and daughters' interested areas of business.

Pregnancy is a task of creation in which a women mobilizes her self and the resources available to her in the generation of a new person. Through the pregnancy, a mother has formed the new human relationship with a fetus. Maternal-fetal relationship is considered one of mechanism making the relationship of mother and child. It is important to well-being of mother and fetus, too. The earliest interaction between a mother and her child is during prenatal period. Maternal-fetal dyad is unique and perceived interactions with the fetus make the pregnancy real for the mother. Maternal behavior is "instinctive" and is formed in early childhood by copy of the mother. But, Rubin argues that this behavior is an open intellectual system rather than a prepackaged bundle of traits. There is openness to new learning and a high value placed on knowing which occurs with silent organization in thought. Thus, nurses and other health professionals provide prenatal care that optimally is part of the environment in which the maternal-fetal dyad develops. Thus it is appropriate for nurses to increases their understanding of the dyad and to explore ways to enhance its development. This study focusses on the interaction ability and response of fetus, and the maternal-fetal interaction. The research of fetal responses that involve physiological changes and motor movement have been shown to coccur to both external sensory stimuli and to maternal emotional states. The fetus does also have sensory capacity to be aware of some maternal behaviors, and the motor ability to respond in a way the mother can notice. Thus, very rudimentary interactions appear to be possible. Maternal awareness of fetal activity was supported by several studies. More interesting to the present study are description of maternal-fetal interaction and the finding that there appear to be levels of sensitivity to the fetus involved in maternal-fetal interactions. First, recognition comes that the fetus is separate from the maternal self. Next, the fetus engages in. Lastly, the parent may describe active interaction with the fetus, believing that mother and fetus are communicating on a meaningful level. Several interventions, developed to promote more active interaction between mother and fetus, have been reviewed. In general, the parents were taught to stimulate the fetus and to notice the fetus' responses. This type of intervention might increase the mother's sensitivity to her unborn baby, and she may have a head start toward learning how to res pond sensitivity to the newborn infant. Research In the area of maternal-fetal interaction is scarce. Sensitive behavior is construed as an appropriate and timely response to a signal of need from another person, but no such signal of need can be claimed regarding the fetus. The highest level of maternal-fetal interaction, therefore, might be based more on maternal representations of the imagined fetus than on factual evidence of fetal participation.

Students have chosen the various behaviors to prepare for the future during the university life. In general to be employed by someone and to create one's own business is likely to be regarded as difference ways. The objectives of this study is to find that whether student's planned behaviors such as albeit, internship, getting some certification are to be related with entrepreneurial intention, and entrepreneurial intention has positive relation with entrepreneurial decision makings based on theory of Planned behaviors through empirical study. In order for that, this study sets four research hypothesis. In the empirical findings, 3 research hypothesis except H2 (subjective norms have positive relations with entrepreneurial intention) are accepted in statistically. Considering research findings, students' planned behaviors, such as albeit, internship, getting some certifications to have been regards as far away from entrepreneurship have positive relation with entrepreneurial intention and implementation. Entrepreneurship education and knowledge regarding start-ups given by Universities or private institutions should provide information to create imagination new venture business with spontaneity instead of giving intented contents concerning entrepreneurship when taking into consideration of result of hypothesis 2. In order words, entrepreneurship education to provide the self-efficacy is the right track for students.
