If roads, bridges, buildings, etc. are built on the ground with soft clay or organic soil, there may be a lot of problems in geotechnical engineering such as settlement and stability due to the large settlement and lack of bearing capacity. In extreme cases, it may appear due to shear failure or collapse of the constructed structure, so a ground improvement method is indispensable to increase the strength of the ground and to suppress settlement. In this study, the settlement according to each groundwater level condition was analyzed using the measurement results for the groundwater level conditions, one of the important factors in predicting the settlement in dredged and reclaimed ground, and the groundwater level conditions applied to the settlement analysis were proposed by comparing it with settlement generated 5 years after construction. As a result of the analysis, it is judged that it is reasonable to apply the measured groundwater level during construction and the low water ordinary neap tide (L.W.O.N.T) during load application for the groundwater level in the settlement analysis. In addition, in the case of the dredged and reclaimed ground, it is estimated that the water pressure acting on the clay layer is nonlinear, as the result of the observations of the head of water at the observation points above and below the in-situ clay layer were different.

This study examined the problem of entrepreneurship education in Korea, which equate entrepreneurship with startups, unlike the global trend of approaching entrepreneurship with a broad concept. On the basis of overseas cases such as European Union and OECD, this study derived the need for entrepreneurship education from the perspective of thinking and behavioral patterns. In addition, Q methodology was used to reason out various recognition patterns and approach solutions for problems of entrepreneurship education in Korea, such as awareness of the need for entrepreneurship education in concepts separate from start-ups, reasons for infertility, and why it is difficult to activate. This approach was conducted for educators and educatees that carries out entrepreneurship education in Korea. In conclusion, there were four types of subjective perceptions about the difference of entrepreneurship education and startup education, and three types were recognized for the need to differentiate entrepreneurship education from startup education, and the two types that made up the upper majority strongly supported the need for entrepreneurship education to be implemented individually. According to the conclusion, this study proposed the development and spread of common teaching materials made by the Ministry of Education and Ministry of SMEs and Startups, which is the competent Ministry, to train professional teachers, training methods, and continuous refresher education. It also proposed that there should be a social atmosphere for eliminating rejection of entrepreneurship not only among the youth but also the adult population, and for continuous awareness of concepts that can be applied within the organization and the community, and that a policy basis is required to do so.

The apple rootstock M.26 (Malus pumila) is very popular apple rootstock with semi-dwarf habit and the trees on M.26 produce high quality fruit at a young age. Since it is prone to poor prop ability to soil, however, young trees require staking in windy locations. The rolC gene was introduced into M.26 by Agrobacterium tumefaciens LBA4404 harboring pBI121 to obtain its transformants with dwarfism and enhanced rooting ability. One regenerated transgenic line was confirmed by polymerase chain reaction (PCR) analysis and Southern blot analysis of genomic DNA for the existence of rolC gene. The characteristics of transgenic line in vitro were not significantly different from non-transgenic line except for the active root formation and lateral root number. The rolC transgenic line showed reduced stem length and increased root number in vitro. Rooting ability was examined in the isolated greenhouse after mound layering. Compared to non-transgenic M.26, rolC transgenic line showed significantly higher rooting ability. The transgenic line did not show any other observable variation in shoot phenotype compared with non-transgenic line excepting increased branching

Emotional labor is the process of regulating feelings or emotions and expressing them in the way that fulfill job requirement. There have been many studies about characteristics or related variables of service workers' emotional labor, but are few studies comparing emotional labor between service workers and non-service workers. Therefore we are to examine the differences of emotional labor among the different types of workers. And as depression and lowered quality of life are well known negative consequences of emotional labor, we also intend to study the relationship between depression, quality of life, and emotional labor. Data were collected from 125 sales workers, and 186 cyber university full time students. And as to assure the student participants to be non-service workers, we limited the participant job as administrator, soldier or housewife. To compare differences of groups, one-way ANOVA was performed with Fisher's LSD as post hoc comparison. On overload in customer reception, service workers showed significantly higher scores, and on demand of emotional regulation/emotional dissonance/depression, both service workers and housewives showed significantly higher scores. Also analysis of multiple regression was performed, and the result showed that, emotional dissonance increased depression but decreased quality of life, while support/care increased quality of life, but decreased depression. With the result, implications and limitations of this study were discussed.

This study was conducted to understand and describe Korean nurses' perception of person-centered care for elderly patients in long-term care hospitals. Qualitative data were collected through four focus group interviews consisting of 21 nurses working in four long-term care hospitals in Jeolla and Gyeongsang provinces. Participants completed interviews from July 19 to 30, 2018. All interviews were recorded, transcribed, and analyzed by employing the thematic analysis method. Six main themes for the attributes of person-centered care for elderly patients in the long-term care hospitals were conceptualized: respecting individual needs, walking to the end, supporting hidden dreams, becoming a family partner, helping patients live like they are at home, and changing culture. Person-centered care perceived by nurses was conducted to provide individualized nursing according to elderly's preferences and help them discover the value and meaning of life through various activity programs. Nurses also recognized person-centered care to maintain cooperative relationships with their family members and share their decision-making process, as well as to form a physical environment and organizational culture that respects the rights and autonomy of the elderly. Based on the results of this study, it is necessary to identify the diverse needs of the elderly and develop nursing intervention programs based on person-centered care.

The purpose of this study is to investigate the relationship between transaction justice and customer performance. In this study, data were gathered from questionnaires from customers and suppliers of manufacturing outsourcing service, and reliability, validity, and confirmatory factor analysis (CFA) were conducted and the hypothesis was verified through the structural equation modeling (SEM) analysis. The results of this study are as follows: 1)Transaction justice has a significant positive effect on customer's business performance. Distribution and Interactional justice have a small effect on business performance, but Procedural justice has a significant positive effect. 2)Transaction justice has a positive effect on partnerships. 3)The partnership between the customer and the supplier has a positive effect on the customer's business performance. 4)Partnership has positive effect on customer's management performance through mediating justice. This study is based on the fact that justice acts as a independent variable in the transactional relationship between the customer and the supplier in the manufacturing outsourcing and this is the first case that empirically investigated the effect of the justice on the customer's management performance. In order to effectively cope with a rapidly changing business environment and effectively improve management performance, it is necessary to make efforts to improve justice, especially procedural justice, by utilizing outsourcing effectively in a global competition. In this respect, this study provides important implications for the both academically and practically.

This study is a quasi experimental study to investigate the effects of stroke prevention education program of Oriental Nursing on self-health perception, health behavior change, self-care and physiological index of adults over 55 years old and elderly people. The data were collected from August 12 to November 29, 2017. The 53 study subjects comprised 26 experimental subjects who agreed to participate in the education program and 27 control subjects. In the results, there was no statistically significant difference between the experimental group and the control group in general characteristics and research variables before the program; further, the two groups were homogenous. In the hypothesis test, the change in self-health perceptions of the experimental and control groups was t = -5.28 (p <.001), health behavior change was t = -4.24 (p <.001), self-care was t = -5.28 (p <.05), systolic blood pressure was t = 2.48 (p <.05), diastolic blood pressure was t = 2.78 (p <.05), and cholesterol was t = -3.94 (p <.001). There were statistically significant differences between the two groups and all four hypotheses were supported, which demonstrated the effectiveness of the program. These study results suggest that it is an effective program to change the self-perception of health and health behavior, improve self-care ability, and control the physiological index. It is expected that these findings will be useful in developing a future effective oriental nursing intervention. The education program should be continuously carried out, and the area needs to be expanded.

This study aims to conduct a comprehensive analysis of how the presence or absence of a partner affects the life characteristics of persons aged 65 or older. For this, the subjects were divided into the married group and the single group to investigate sociodemographic characteristics, health conditions, self-rated health level, disease morbidity, limitations in life due to health conditions and health-related quality of life. An assessment was carried out by analyzing local communities' health survey data of 3 years from 2014 to 2016. The results revealed that the single group had more women, a lower household income, poorer health conditions, and a higher chronic disease morbidity rate than the married group, and thus their self-rated heath level was lower as well. These characteristics were found to contribute to a lower quality of life in the single group than the married group. To this day, we have viewed the elderly as one of the groups based on age and only tried to identify their average characteristics, thus overlooking their various inherent problems. The results of this study suggest that physical, emotional and social problems seen among the elderly need a comprehensive measure. In addition, this study found that public health approaches and social welfare systems should be improved to develop personalized support programs for the elderly.

For a marine bridge foundation construction, a large-circular-steel-pipe has been proposed for supporting vertical load and preventing water infiltration. However, a ship collision can adversely affect the structural stability. This paper presents a fundamental study on dynamic responses of the large-circular-steel-pipe by an impact load. In laboratory experiments, small-scaled steel pipe is installed in a soil tank. The soil height and water level are set to 23 cm and 25~70 cm, respectively. The upper part of the steel pipe is impacted using a hammer to simulate the ship collision. The dynamic responses are measured using accelerometers and strain gauges. Experimental results show that the strain decreases as the measured location is lowered. The higher frequency components appear in the impact load condition compared to the microtremor condition. However, the higher frequency components measured at the strain gauge located below the water level do not appear. For the accelerometer signal, the maximum frequency under the impact load is higher than that of the microtremor. The maximum frequency decreases as water level increases but it is larger than the maximum frequency of the microtremor. This study shows that strain gauge and accelerometer can be useful for evaluating the dynamic responses of large-circular-steel-pipes.
