  • The structural space is gradually wide and is wanting agreeable environment by the requirement and necessity of people who lives modem stage. The building coincides with such requirements and is the high rise building actual circumstances which is doing ultra-large. The confirmed report of the technology to organize great merit is becoming currently considerably important issue in constructing a building field. Thus, this paper examine closely for nonlinear unstable taking a picture uneasiness height of prosperity considering to initial imperfection by a numerical method with a space frame structure of discrete system in large space structure. Based on previous investigation method, this paper induce nodal stiffness matrix of solid truss elements considering geometrical nonlinear using finite element method. In this paper, three types of space structure considered; i) 1-free node space structure, ii) 2-free node space structure, iii) multi-free node space structure.

  • This study is a follow-up to Lee(2019). Lee(2019) investigated the method of collecting information on the curriculum of elementary and middle school math teachers, when differences were observed between elementary and middle school math teachers in the method of collecting information on the curriculum. Following Lee(2019)'s study, this study looked at the perceptions and experiences of high school math teachers in their curriculum.At the time when the curriculum was changed from time to time, the authority for restructuring curriculum was strengthened. In addition, the role of teachers as 'curriculum restructuring practitioners' became important. However, previous studies have pointed out the structural problem that teachers empathize with the necessity of restructuring the curriculum and have a negative perception of the willingness to practice the curriculum. Therefore, the researcher examined high school teachers who are sensitive to the characteristics and evaluation of the highly hierarchical mathematics subjects. A total of six interviews were conducted with ten high school mathematics teachers in three groups of ten years of teaching experience. Through this, it was possible to observe how teachers as curriculum reconstruction practitioners had thought about curriculum restructuring, and I could observe what difficulties teachers' experienced. This suggests that teachers have two ideas for restructuring the curriculum: 'realistic curriculum reconstruction' and 'ideal curriculum reconstruction'. In addition, the teachers found that there are 'sides of incongruity in the school system' and 'difficulties in the management of teachers'.

  • Hospitals in Korea have been increasingly using physician assistants (PA) as an alternative way of dealing with the shortage of residents. However, some incidents of a Physician's Assistant practicing beyond their legal scope require closer examination of the current PA's roles and functions. This study is a web-based survey designed towards targeting physician assistants in Korea (KPA) who practice delegated tasks under a physician's license. Currently, there are 2,125 KPAs working in 141 general hospitals and medical centers. Data from 704 nurses from who responded to the questionnaire were analyzed with descriptive statistics using the SPSS 12.0 program. Their mean age is 32.5 years with 8-10 years of clinical experiences, with males being more likely to be a PA. Despite of KPAs providing medical services and performing invasive procedures, only 13% of KPAs are licensed APNs (advanced practice nurse). KPAs have a low job satisfaction due to a lack of rewards and the necessity for providing illegal practices, and are experiencing identity confusion. The current KPA system is a transitional product of the change from the hierarchial structure to a more collaborative relationship between the medical and nursing departments. Providing adequate education and training, establishing protocols with legal protection, and developing professional independent scope of care are recommended to deliver safe and efficient medical services.

  • The purpose of this study was to examine the use of dental institutions among Chinese students in Korea in an attempt to provide some information on how to make more and better dental services accessible to them. The subjects in this study were Chinese students who were studying in eight different colleges. After a survey was conducted from April 1 to July 15, 2011, the following findings were given: 1. Concerning experiences of using domestic dental institutions, the majority of the respondents never received dental treatment in our country. The most widely used dental institutions were dental clinics, and the most common treatment they received was about dental caries. 2. As for the reason why they didn't receive dental treatment in our country, the biggest group cited the burden of medical cost and time constraints as the reasons. 3. The students who had medical insurance slightly outnumbered those who hadn't. Regarding the necessity of medical insurance, most of them considered that to be necessary, and those who had medical insurance received more dental treatment than the others who hadn't. 4. As to satisfaction with dental treatment, the students who were better at Korean expressed more satisfaction, and those who had medical insurance were better satisfied than the others who hadn't. In conclusion, the medical insurance system should be improved to let Chinese students have medical insurance compulsorily to ensure their efficient use of dental institutions, and every college should offer administrative assistance for health care.

  • Background In Sasang Constitutional Medicine (SCM), human beings are classified into four constitutions: Taeyangin, Taewnin, Soyangin, and Soeumin. SCM presents various lifestyles and treatments for each constitution. The problem of SCM is that its diagnosis is so subjective that the result of the diagnosis depends on the doctor. In order to solve this problem, multiple approaches have been objectively researched. To use a questionnaire is the most common method among the different approaches. Since there are a few problems in the Questionnaire for the Sasang Constitution Classification II (QSCC II), which in recent days has been used frequently, the necessity of a new questionnaire has arisen. Objective The purpose of this study is to develop a new questionnaire for the objectivity of the Sasang Constitution Classification by complementing the existing questionnaire. Methods In order to search for the existing questionnaire's problems, I first compare the ratio of the amount of questions regarding external appearance to that of questions of mental characteristics and physiologic & pathologic symptoms in QSCCII and QSCCII +. We created the new questionnaires by reinterpreting ${\ulcorner}Dongyi$ Soose $Bowon{\lrcorner}$ through SCM professors' and medical residents' discussion and by adding some items related to the diagnosis about the constitution from other SCM books and clinical experience. Results 1. The new questionnaire for the Sasang Constitution Classification is self-reported questionnaire based on a multiple choice system of 4 questions. 2. The new questionnaire for the Sasang Constitution Classification consists of 28 questions, which include 7 questions about external appearance, 4 questions about mental characteristics, and 17 questions about physiologic & pathologic symptoms. 3. The new questionnaire for the Sasang Constitution Classification consists of 24 questions of Taeyangin, 28 of Taeumin, 28 of Soyongin, 28 of Soeumin. 4. We will have to verify validity and reliability of new questionnaire for rhe Sasang Constitution Classification.

  • Purpose: This study was performed to explore the current state of end-of-life (EoL) care education provided to new interns at two university hospitals. Methods: A questionnaire was given to incoming interns (N=64). The levels of acquired knowledge and experience of clinical observation were measured. Seven areas for self-assessment questions were identified and used to analyze the interns' attitudes towards EoL-related education and practice. Results: On average, participants learned five elements (nine in total) from EoL-related classes and two (seven in total) from clinical observation. The most frequently educated element was how to deliver bad news (96.9%) in the classroom setting and how to control physical symptoms (56.5%) in clinical observation. Less than 20% received training on EoL care communication, including discussion of advanced directives. Compared with participants who had no EoL training, those who had EoL training showed positive attitudes in all seven categories regarding overall satisfaction, interest and preparedness in relation to EoL-care classes and practice. Conclusion: Although interns are responsible for caring of dying patients, their EoL training in classroom and clinical settings was very insufficient. Further research should be conducted to establish an education system that provides sufficient knowledge and training on EoL care.

  • This paper aims to plan a new research program on the parallel relationship between Korean press and political power, by providing concepts on the mode of existence of professional journalists in Korea. In the midst of the economic crisis of Korean journalism, relative deteriorisation in the political democracy and the liberty of press, and changes in news ecosystem due to the revolution of digital news, the status of professional journalists is at stake. In these circumstances, this paper argues that many existing researches on journalistic professionalism need to be reconstructed in the perspective of professional project. It enables, first of all, an evaluation on actual issues of professional journalists from the actor perspective, i.e. economic interests, social closure, regulative bargain with the authority. Secondly, concerning decoupling phenomenon of journalism and democracy which became salient in the contemporary society, this study raises a necessity to create new logical relations around concepts of journalist professionalism. And we will find, in this situation, a beginning of new evaluation on the mode of existence of professional journalists, that has been possibly developped within the old, assymetric relationship between State-press. And finally, this study proposes to consider a category of professional journalists as a vehicle that helps to conceptualize the old, parallel relationship between Korean press and political power.

  • Biodiesel has very similar physical properties (density, kinematic viscosity) and has even higher cetane number compare with conventional diesel. There are no necessity to change or modify the infra-structure & engine system. It is known that fatty acid methyl ester (FAME) is oxygen-contained components increasing the combustibility, biodegradability and reduced the exhaust harmful gas. These things made the biodiesel more popular as an alternative diesel fuel. But biodiesel's sources are controversial issues about $CO_2$ reduction effect at this time because those mainly come from edible plants such as soy, palm, rapeseed already spent lot of $CO_2$ to cultivate. Whereas micro-algae is focused because they are inedible and has rapid growth rates & high carbon-dioxide adsorption rate per area. In this study, we analyze the each FAME components using $GC{\times}GC$-TOFMS in stead of GC-FID and verify the previous total FAME contents method's applicability through the micro algal biodiesel derived from Dunaliella tertiolecta.
