The study investigated the linguistic characteristics of middle school students' writing on the themes of earth science through analysis of its genre and register. Data for analysis included $7^{th}$ grade and $9^{th}$ grade students' writings about 'global warming' and 'classification of rocks'. The results of this study include: First, many students were not accustomed to writing in genre, especially exposition genre. Second, in terms of ideational meaning, the material verbs representing action or doing were more dominant than relational verbs that are related to the attribute or definition of things, and additional logical relations were predominant. Third, regarding interpersonal meaning, agents, emotions, subjective opinions appeared in the writings and students did not express their ideas conclusively and revealed feelings of doubt and uncertainty about their knowledge. Fourth, as for textual meaning, most students listed fragments of information using additional conjunctions in simple structures and were not accustomed to writing texts with organizing structures, logical patterns, cohesion, and coherence. From these results, we argued that the scientific writings should be emphasized in science learning that aims to foster scientific literacy. In addition, we discussed the necessity of improving science teachers' perceptions on scientific writing as well as setting up a specific plan in the national curriculum.

Today, as individuals show their social identities and reflect their being as the members of society with a culture, an art style and communication function are stood out in fashion photographs. Accordingly, the meanings of images into text are expanded in its interpretative width through the acceptor's various terms. This researcher looked into four theories of both positions on the textuality of language and image, and considered the point of discussion on image of each theory through modern fashion photographs. First, the theory which divides language and image as auditory and visual recognitions in the textuality of language and image is limited from the view it focuses on only one side without considering the ambivalent elements of each field. For the textuality in modern fashion photographs, the observer attempts to turn it into text to give meaning to it as the recognition through five senses conforming to the acceptor's condition. Second, the theory dividing language and image into the text of time properties and spacial properties has limitation in the text, for acceptor's experience of the object appears as the structured form in time and space rather than being defined as two things like time and space. Third, the theory classifying the language and image text into conventional taste and natural taste has limitation from the view that image text is hardly an object of consistent classification in ease of recognition by the code accepted in society. Thus, this can't be fundamental approach for the understanding of the text of decoding trend represented in modern fashion photographs. Fourth, accordingly, this researcher focussed on contextual and arbitrary text of fashion photographs through the theory of Nelson Goodman which discusses image text through the differences in textuality. Basic mechanism of perceiving and recognizing and distinguish image is closely related to habit and custom like language. So, each acceptor perceives the image as a text through arbitrary interpretation obtained by individual, empirical, historical, and educational viewpoints. The textuality of modern fashion photographs aims to widen the range of diverse knowledge and understanding, transcending the regulations of simple function of existing fashion photographs. Consequently, this researcher puts forward the opinion of consistent and diverse follow-up studies on instilling meaning into fashion photographs for the understanding de-regulatory and de-constructive through various senses by avoiding only one sense-dependent fixed and regulatory properties of it.

With the rapid development of IoT(Internet of Things) technology, various convenient services such as smart home and smart city have been realized. However, IoT devices in unmanned environments are exposed to various security threats including eavesdropping and data forgery, information leakage due to unauthorized access. To build a secure IoT environment, it is necessary to use proper cryptographic technologies to IoT devices. But, it is impossible to apply the technologies applied in the existing IT environment, due to the limited resources of the IoT devices. In this paper, we survey the classification of IoT devices according to the performance and analyze the security requirements for IoT devices. Also we survey and analyze the use of cryptographic technologies in the current status of IoT open standard platform such as AllJoyn, oneM2M, IoTivity. Based on the research of cryptographic usage, we examine whether each platform satisfies security requirements. Each IoT open platform provides cryptographic technology for supporting security services such as confidentiality, integrity, authentication an authorization. However, resource constrained IoT devices such as blood pressure monitoring sensors are difficult to apply existing cryptographic techniques. Thus, it is necessary to study cryptographic technologies for power-limited and resource constrained IoT devices in unattended environments.

The purpose of the present study is to confirm the interacting behavior between nurses and patients and other things concerned herewith. Subjects of investigation were : 42 nurses selected out of the average nurses who serve in hospital as nurses assigned to medical and surgical wards : and 42 male and female adult patients selected out of the average patients who were under the care of the nurse individuals and can make themselves understood verbally. A nurse and her patient were paired off for questioning. Materials for statistics were gathered by means of observaing interactions- - verbal and nonverbal - -of the chosen subjects for four hours every day from 7 : 30 a.m. through 7 : 30 p.m. between on July 15, 1988 and on Aug. 16, 1988. Classified by patterns, the materials observed and gathered were preliminarily analyzed by this researcher, and then reexamined in a full-fledged way by one professor, three nurses and three non - nurses. The researcher depended chiefly on Frequency, ANOVA, Pearson's Correlation Coefficient attached to SPSS Computer System for the process of gathered materials. The results of this investigations are follows 1) A total of 98 times' interactions between nurses and patients were provided during observation of 168 hours. 2) It took them the averaged 264.8 seconds(around 4.4 minutes) per a couple of subjects to interact between nurses and patients during observation of four hours. 3) The aim of interactions between nurses and patients appear that 29 times of injection amounted to 29.6% the most, 27 times of PO around to 27.6% the next most, 25 times of vital check to 25.5% the next most, 17 times of independent nursing works and round to 17.3% the least most. 4) As a result of qualitative analyzing the interactions between nurses and patients by the distinctive method of words were positively recognized in 19 cases with 45.2% and negatively in 23 cases with 54.8%. 5) A total of 2, 193 times. interaction behaviours between nurses and patients were provided. The frequency of these interaction behaviours took place l, 364 times with 62.2% to nurse, and 829 times with 37.8% to patients. 6) The classification of verbal and nonverbal interaction behaviour between nurses and patients indicated that it is amounted to 64.9% for verbal behaviour numbered 1, 423 and 35.1% for nonverbal one numbered 770. 7) The frequency of verbal behaviour between nurses and patients numbered 1, 423 in total. They took place 924 times to nurses and 499 times to patients, it can be also amounted to 64.9% and 35.1% respectively in percentagewise. 8) In interactions between nurses and patients, it turned out that the frequency of nurses' turns, which the present research discovered averaged 16.8 times for four hours, and the verbal behaviours by numbered 9.7 on an average. 9) Nonverbal behaviours between nurses and patients numbered 770 in total, it is assigned 440 times to nurse with 57.1% and 330 times to patients with 42.9%. 10) The investigation releases in formation that the frequency of verbal behaviours between nurses and patients was very much concerned with the age of patients(r＝0.422, p＜.01) and the number of patients one nurse has under her care(r＝-0.356, p＜.01). 11) It was found that were deep relationship of the number of a nurses turn with the patients age(r＝0.377, p＜.01) and the nurses burden of caring patients(r＝-0.372, p＜.01).

Objective : The aim of this study is to analyze medicinal herbs, the ingredients of traditional Korean liquor, focusing on efficacy in the traditional Korean medicine. Through this study, for vitalizing traditional Korean liquor market, the researchers attempt to explain the superiority of traditional Korean liquor and the advantages of using herbs to brew alcoholic beverages. Method : We conducted a research targeting traditional Korean liquors in domestic market from July through september 2012, and finally 70 kinds of liquor were selected and analyzed. Results : Among traditional liquors, fermented liquors are most common. When comparing regions of brewery, the central region of Korea, Gyeonggi-do and Chungcheongnam-do, is major brew area. 37 liquors contain just one medicinal herb. followed 10 liquors contain two medicinal herbs. The most frequently used medicinal herb is Ginseng Radix. And Lycii Fructus, Schisandrae Fructus, Angelicae Gigantis Radix and Chrysanthemi Indici Flos are well used medicinal herbs to brew traditional liquors. In the classification of efficacy of medicinal herbs, tonifying and replenishing medicinal herbs are most popular as ingredients in the traditional alcohols, astringent medicinal herbs, exterior releasing medicinal herbs and heat clearing medicinal herbs are also frequently used. Investigation of tastes and properties of the herbs, it reached a conclusion as below: sweet taste is most common, followed by sour taste and bitter taste. Warm property is account for 50% approximately, followed by cold property. Conclusion : Medicinal herbs have been widely used in the traditional Korean liquor. It came out into the open that the liquor with medicinal herbs is very good for our body in terms of longevity and invigoration. However, liquor consumers concern about not only the efficacy but also the taste, scent and color. Therefore, further study about these things would be required to demonstrate the superiority of the traditional Korean liquor.

This paper examines the situation and tasks of competitive systems of EU transport market focusing on railways. Recently, the EU transport market has changed radically, thanks to an increasingly competitive rail market. The European Commission has stimulated the creation of a competitive environment that will enhance the position of rail. Some scholars have insisted that the rail market is more monopolistic than competitive. However, the case of UK rail privatization suggests this is not the case. Moreover, some countries have a rail market that is more competitive. We draw on a wide range of sources including statistics and analyses of recent phenomena. These demonstrate the emergence of competitive markets in EU rail and the difficulty of developing a competitive market. With regard to the adoption of the competitive market, we examine three things. First, we observe recent cases and trends in competitive markets. Second, we compare the result of competitive markets and non-competitive markets within EU nations. Third, we demonstrate factors of formation of competitive markets and the possible expansion. We identified differences within open market policies amongst EU nations. Although a competitive EU rail market may have some difficulties, it will steadily begin to overcome technological differences and a lack of funds, because EU countries have a common goal, which is to develop the railways, solving, wherever possible both environmental and energy problems. Through this analysis, we found that the free market in EU rail will be extended to deliver efficiency and quality service.

This paper examines the characteristics of the traditional education contents that they have preserved and succeeded based on the recognition of 'Dongdo' by the modern intellectuals, and selects the contemporary contents of traditional education which are worthy of modern succession, It is aimed to categorize by classification and to reconstruct the contents accordingly. For this purpose, I will try to diagnose the problems of modern education and explore the possibilities of traditional ideas represented by Confucianism as a solution to solve and solve these problems. In particular, I will examine the positive and negative perceptions of intellectuals about studying abroad since the modern era, and examine what are the meaningful things to avoid and how to reconstruct the contents of traditional education in a modern way. Through this review, I will establish the principles for the modern reconstruction of the contents of the traditional education and finally discuss the parts that should be emphasized in the modern reconstruction of the contents of the traditional education and the composition of the alternative contents.

Traditionally used for networking computers and communications, the Internet has been evolving from the beginning. Internet is the backbone for many things on the web including social media. The concept of social networking which started in the early 1990s has also been growing with the internet. Social Networking Sites (SNSs) sprung and stayed back to an important element of internet usage mainly due to the services or provisions they allow on the web. Twitter and Facebook have become the primary means by which most individuals keep in touch with others and carry on substantive conversations. These sites allow the posting of photos, videos and support audio and video storage on the sites which can be shared amongst users. Although an attractive option, these provisions have also culminated in issues for these sites like posting offensive material. Though not always, users of SNSs have their share in promoting hate by their words or speeches which is difficult to be curtailed after being uploaded in the media. Hence, this article outlines a process for extracting user reviews from the Twitter corpus in order to identify instances of hate speech. Through the use of MPCA (Modified Principal Component Analysis) and ECNN, we are able to identify instances of hate speech in the text (Enhanced Convolutional Neural Network). With the use of NLP, a fully autonomous system for assessing syntax and meaning can be established (NLP). There is a strong emphasis on pre-processing, feature extraction, and classification. Cleansing the text by removing extra spaces, punctuation, and stop words is what normalization is all about. In the process of extracting features, these features that have already been processed are used. During the feature extraction process, the MPCA algorithm is used. It takes a set of related features and pulls out the ones that tell us the most about the dataset we give itThe proposed categorization method is then put forth as a means of detecting instances of hate speech or abusive language. It is argued that ECNN is superior to other methods for identifying hateful content online. It can take in massive amounts of data and quickly return accurate results, especially for larger datasets. As a result, the proposed MPCA+ECNN algorithm improves not only the F-measure values, but also the accuracy, precision, and recall.

The purpose of this paper is to provide basic data to Si and Gun preparing for rural agreements in the future through consideration and case analysis for rural conventions, such things as living standards, hierarchical analysis methods, and general rural development projects. In the 1970s, sporadic and one-off projects focused on individual projects were repeatedly carried out in rural areas, which were undergoing dramatic changes in population movement, land use, landscape, economic growth and living. The keyword of the government's policy has changed to a way that existing rural development projects are planned and promoted by local governments themselves in conjunction with the issue of autonomy and decentralization. In addition, with the introduction of Rural Convention, the central and local governments are striving to achieve common policy goals. However, due to the lack of understanding of the Rural Convention introduced as a pilot project in 2020, the lack of living areas setting-standards, unclear classification of hierarchical structure, and excessive goal consciousness for general agricultural and fishing village development projects remain, fading the original purpose of the Rural Convention. Therefore, this study analyzed the seven reports of the Gyeongsang region selected in the 2021 Rural Convention to identify the characteristics of living area, hierarchical structure analysis, and detailed projects (rural center revitalization project, basic living base development project) and provided them as basic data. As a result of the study, first, according to the results of the hierarchical structure analysis, the first class was derived from 6 out of 7 Si and Gun. This is judged to be the result of the current rural population, social, and economic problems. Second, according to the results of the division of living areas, it was confirmed that except for one local government in seven cities and counties, the remaining six local governments were divided into three single living areas and three two living areas. This is the result obtained through a comprehensive review by overlapping the results of various analyses such as hierarchical analysis and resident surveys and OD data, and shows a different form from the existing upper or related plans. It is judged that this is the result of including qualitative contents such as residents' opinions along with various analyses when determining the living area. Third, the proportion of the budget for rural center revitalization and basic living base development projects to the total project cost subject to the Rural Convention was 59.6%, which was relatively higher than that of other general agricultural and fishing village development projects. It is judged that it is preferred because the unit project cost is relatively high in Si and Gun, and that quantitative results can be visually shown after the project is terminated.
