The purpose of this study was to present a method for the application of drones through analysis after surveying Jeollanam-do firefighters regarding the recognition, operation, field of application, necessary field of work, and the need for education on fire drones. As a result of the survey, 80.29% of respondents were found to be willing to operate drones, and the fields of work for which drones were considered the most necessary were in the order of rescue, fire suppression, life safety, first aid, and others. Besides, 77.38% of respondents thought that drones could contribute to the prevention of safety accidents for firefighters, and 70.13% of respondents thought that it would be appropriate to recruit firefighting drone operators through changing positions, and respondents chose firefighters in their 40s as the most suitable age group for firefighting drone operation. Also, 82.84% of respondents said they would participate in drone training, and they recognized that the use of drones could contribute to solving the physical problems caused by the aging of firefighters, and that drone training would also help firefighters manage their retirement. The fields where firefighting drones are used were investigated in the order of searching for requestors, checking on-site information, and checking on-site prior risk. In this study, a difference analysis for each group was performed according to the drone operation experience. There was a statistically significant difference in the items of safety measures for requestors. The results of variance analysis by work experience confirmed that there were statistically significant differences in a total of eight items, including four items related to the field of use of drones, and the age group of the drone operating crew, and whether or not to help retirement management.

The purpose of this study is to summarise the educational meanings of Official Foreign Language Schools(hereafter, OFLS) in Korea, 1895-1906. Especially, I try to find out the foreign language policy of the Joseon Dynasty and the comparative superiority between six foreign language schools - Japanese School, English School, French School, Russian School, Chinese School, and German School - through the traits of teachers and the change of students numbers at the Regulation Period. As a part of Kabo Reforms, the government had abolished the of Civil Service Examination System and status system, and foreign languages worked as a cultural capital to acquire modern civilization and to escalate one's social status. The results were as follows: Firstly, the OFLS have to be regarded as one of the highest educational institute during the Regulation Period. The eligibility of the OFLS was over 15 years old, but most of the incoming students were over 20 years old. Secondly, many of the OFLS's teachers were specialists of military, diplomat and mechanics. Especially, Martel, the teacher of French school played an important role for the neutral diplomacy policy of the Great Korean(Dae-Han) Empire during the Regulation Period. Thirdly, the recruit of new members of the OFLS was affected by the political and social circumstances at that time. Fourthly, the statistics of incoming students during the Regulation Period was concentrated on Chinese school, French school, and English school in due order. Thus, it differed from the commonly accepted ideas of students' statistics which was concentrated on English School and Japanese School. Fifthly, the OFLS were not only for the training of official interpreters(譯官通事), but also the cultivation of civil servants who could become statesman.

Sinheung Military Academy was the first one which prepared for independence war built by members of Sinminhoe in Western Manchuria. Sinheung Military Academy is known that nurtured 3,500 independence soldiers during 10 years from 1911 thorough 1920. Nevertheless no people know how it recruited so many students for 10 tears. In the course of studying the recruit of Sinheung Military Academy, I became to focus on Manjugisa by Yi Sang-nyog. Although Yi Sang-nyon remembered that there were over five hundred students in Sinheung Military Academy from just after it's set up in Manjugisa, scholars overlooked that mention so far. In addition, in the Sixth poem of Manjugisa, Yi Sang-nyong recollected that there were 30 preliminary educational organizations in 1918 after installation of Sinheung Military Academy in 1911. Therefore I concluded that the over 500 students nurtured from just after installation of Sinheung Military Academy were summed up students of preliminary educational organizations over Sinheung Military Academy's and proved it. The students of preliminary educational organizations in Liuhexian Tonghuaxian entranced into Sinheung Military Academy after graduation. The graduates of Sinheung Military Academy taught the students of preliminary educational organizations a common and military educations in duty for two years. In conclusion, Sinheung Military Academy and nearby preliminary educational organizations were an wide military camp organically maintained by Korean in Western Manchuria for big purpose of independence war.

Objectives : Based on the fact that cognitive functions decline known as comorbid symptoms of depression can precede depression, this study seeks to observe the effects of depressive symptoms and anxiety symptoms on cognitive function in healthy subjects. Methods : To recruit 50 general populations to evaluate cognitive and clinical symptoms and to find out the effects of clinical symptoms on cognitive functions, Pearson correlation and multivariate regression were conducted. Correlation analysis of subdomain cognitive function was conducted for reliability analysis. Results : Trail making test-B that evaluates the execution function correlates with depressive symptoms (r=0.300, p=0.03) and age (r=0.323, p=0.02). Depressive symptoms (β=0.304, p=0.03) and age (β=0.335, p=0.01) were significantly related to Trail making test -B (Adjusted R²=0.148). Subjective cognitive tests correlates with anxiety symptoms (r=0.434, p=0.002). In the correlation between cognitive functional items, Subjective cognitive tests was found to be correlated with other test except Spotter. Conclusions : In this study, depressive symptoms contribute independently to executive functions in addition to demographic characteristics such as age and duration of education. Given that cognitive decline is a common long-term clinical outcome in depression, we expect active early intervention and evaluation of cognitive function to be helpful.

In order to experience and compete in car racing in reality, the barrier to entry is very high. It takes a lot of money and time to recruit or participate in a license, expensive vehicle, and stadium where the game can be played. Because of this problem, various equipment is used to create a feeling similar to real racing in their own space through sim racing equipment. Equipment similar to this reality is called sim racing equipment. The sim racing equipment can be divided into three categories. The first is a racing game device that can run virtual racing, the second is a steering wheel, seat, and cradle that are linked to the racing game device, and the third is a racing motion device that allows the body to experience the direction of movement in the racing game. In this thesis, the feeling of real car racing is based on game racing, and how similar reality to real racing is through the steering wheel and cradle equipment, which are equipment that can control game racing, and motion equipment that allows you to experience the direction of game racing. Let's check how the difference between real racing and data value changes through the G-Force direction and speed change values.

The outer membrane of Gram-negative bacteria is the outermost layer of cellular environment in which numerous biophysical and biochemical processes are in action sustaining viability. Advances in cell engineering enable modification of bacterial genetic information that subsequently alters membrane physiology to adapt bacteria to specific purposes. Surface display of a functional molecule on the outer membranes is one of strategies that directs host cells to respond to a specific extracellular matter or stimulus. While intracellular expression of a functional peptide or protein fused to a membrane-anchoring motif is commonly practiced for surface display, the method is not readily applicable to exogenous or large proteins inexpressible in bacteria. Chemical conjugation at reactive groups naturally occurring on the membrane might be an alternative, but often compromises fitness due to non-specific modification of essential components. Herein, we demonstrated two distinct approaches that enable site-specific decoration of the outer membrane with a fluorescent agent in Escherichia coli. An unnatural amino acid genetically incorporated in a surface-exposed peptide could act as a chemoselective handle for bioorthogonal dye labeling. A surface-displayed α-helical domain originating from a part of a selected heterodimeric coiled-coil complex could recruit and anchor a green fluorescent protein tagged with a complementary α-helical domain to the membrane surface in a site- and hetero-specific manner. These methods hold a promise as on-demand tools to confer new functionalities on the bacterial membranes.

DNA methylation is involved in epigenetic processes such as X-chromosome inactivation, imprinting and silencing of transposons. DNA methylation is a highly plastic and critical component of mammalian development The DNA methyltransferases (Dnmts) are responsible for the generation of genomic methylation patterns, which lead to transcriptional silencing. The maintenance DNA methyltransferase enzyme, Dnmt 1, and the de novo methyltransferase, Dnmt3a and Dnmt3b, are indispensable for development because mice homozygous for the targeted disruption of any of these genes are not viable. The occurrence of DNA methylation is not random, and it can result in gene silencing The mechanisms underlying these processes are poorly understood. It is well established that DNA methylation and histone deacetylation operate along a common mechanistic pathway to repress transcription through the action of methyl-binding domain proteins (MBDs), which are components of, or recruit, histone deacetylase (HDAC) complexes to methylated DNA. As a basis for future studies on the role of the DNA-methyl-transferase in porcine development, we have isolated and characterized a partial cDNA coding for the porcine Dnmt1. Total RNA of testis, lung and ovary was isolated with TRlzol according to the manufacture's specifications. 5 ug of total RNA was reverse transcribed with Super Script II in the presence of porcine Dnmt 1 specific primers. Standard PCRs were performed in a total volume of 50 ul with cDNA as template. Two DNA fragmenets in different position were produced about 700bp, 1500bp and were cloned into pCR II-TOPO according to the manufacture's specification. Assembly of all sequences resulted in a cDNA from 158bp of 5'to 4861bp of 3'compare with the known human maintenance methyltransferase. Now, we are cloning the unknown Dnmt 1 region by 5'-RACE method and expression of Dnmt 1 in tissues from adult porcine animals.

This study has compared South Korea with Taiwan, a society which has an almost non-hierarchical college culture in spite of its social and historical similarities to Korea, including the recruit system. By the means of quantitative and qualitative comparative studies and analysis, it has tried to clarify the reasons behind the hierarchical and sexist military culture of Korean universities. According to the comparative studies, Taiwan's college culture is less hierarchical than that of South Korea, and support for the necessity of hierarchy is weaker. Hierarchy had a greater influence on the payment of meals, appellations and society admissions in South Korea. Elements of military culture such as violence or group discipline were usually only present in South Korean college culture. Male-centered drinking and prostitution culture was also found to be stronger in South Korea. The historical and social reason for these differences is that Taiwan has a weaker basis for nationalism and militarism, both essential factors in the founding of hierarchical and collective culture. The most direct reason for the lack of hierarchy in Taiwanese college culture is the period of recruitment. In South Korea, young men usually apply for military service during the first or second year or college, and return to school as second or third-year studies. In Taiwan, however, men are usually recruited after having graduated from college. Students who have served in the army have proved to have a significant influence on violence, hierarchy and drinking culture in Korea's college culture. South Korea's college culture has two main problems. The first is that South Korean college students are not able to be critical towards the harms of South Korea's oppressively hierarchical collective culture, and therefore do not develop the strength to fight against it. This is all the more problematic because they are the future components of South Korea's main institutions. The second is that it roots male-centeredness even further into the South Korean mentality.
