The purpose of this study is to examine the narrative correlation of nonverbal signs found in Charade. Charade, by using nonverbal signs, provides information about the character's psychological change, his or her relationship with others, and the places where they stay. The study of Charade, then, has to be approached considering not only the transmission of messages through nonverbal signs but also its signification. This study has analyzed the narrative and formation process of the subject that triggers the subject's activity by taking narrative semiotics to the film Carol (2015). As the status of women is represented by the mise-en-$sc{\grave{e}}ne$ at this time, this study aims to examine such a fact through Charade, which belongs to the realm of mise-en-$sc{\grave{e}}ne$. In this study, nonverbal signs that are used in Charade are drawn based on the nonverbal communication theory. The result of analyzing the texts showed that the use of interior decoration was outstanding in the process of expressing the status of female subjects. The use of gaze was noticeable in the process of expressing the acquisition of female subjects' power. Besides, it should be noted that the use of nonverbal signs such as accessories, territoriality, or gesture, was worthy of attention. It was confirmed that such nonverbal signs play an important role in the formation of subjects and configuration of narrative transformation.

The purpose of this study is to analyze the personality level of industrial-field specialized high schools and Meister high schools. The study objective for this is to analyze the differences per background variable and personality level of students of industrial-field specialized high schools and to analyze the differences per background variable and personality level of students of industrial-field Meister high schools. The study result is as follows. First, students of industrial-field specialized high schools showed personality level above normal in all 10 virtues, but this value fell short of the average for high school students suggested in Hyeon et al(2014). Second, students of industrial-field Meister high schools showed personality level above normal in all 10 virtues, and compared to the average for high school students suggested in Hyeon et al.(2014), categories of consideration and communication, manners, honesty/courage, and justice showed values below average. Third, students of industrial-field specialized high schools and Meister high schools showed differences in personality level according to nurturing style of parents, respect for teachers, stress for academic achievement, and school satisfaction, and additionally, students of Meister high schools showed differences in personality level according to career plans. That is, when the student perceived his/her parents to put higher value on his/her happiness rather than academic achievement, when the student respected the teacher, and when the student was more satisfied with te school life, the student showed higher personality level, and in case of students of Meister high schools, the student with detailed plan for his/her career showed high personality level than the student who has not yet decided on his/her career.

With emphasis on various local cultures to confront the Western central culture, Ngugi wa Thiong'o proposes them 'to move horizontally' so as not to repeat the oppressive culture of the West. We need not only dialogues between dominant languages and peripheral languages, but also between marginal languages. With respect to this point, Ngugi thinks that translation itself could be very effective. Ngugi wants to stimulate writing and speaking in marginalized languages and promote translation as a means of making these languages visible. He regards translation as a conversational tool among languages and cultures in the multicultural global community. As is already well known, his determination to write his later works only in his native Gikuyu language has a great meaning in his anti-colonial as well as anti-neocolonial movement. Its proof is his recent effort to cooperate with Jalada Africa. Simon Gikandi criticized the English translation of Matigari as a denial of cultural hegemony of Gikuyu language and its subordination to the global cultural market. However, the concept of 'thick translation', helps us move from Gikandi's doubt of the 'epistemology of translation' to a meaningful strategy of postcolonial translation. Facing some of the scholars' doubts related to his over-stressing language problem, Ngugi points out that the world has managed to function well through translation: the possibility of translation between cultures and translation as a mediating tool for communication nationally as well as internationally. Based on this two-sided solution of translation, he believes that we can overcome the opposition between relativity and universality, center and periphery, and the dominant and the subordinate.

This study try to establish the method on the archiving of a village experimentally. For this study three standpoints were investigated. We discriminate between the theory and practice on general archives management and village archiving. We should grasp that the practice of village archiving is a means to the movement of village community reconstruction. And we clear up the point that village archiving head for the community ownership and the communication. This study clarified what were the constituent units in a village and what were the archives that were producted by the constituent units in a village. It is helpful for the development of the strategy on a village to identify concretely the objects of village archiving. The main body who lead the village archiving is not archivist only. But he should be a man who serve his community and have the competency to deal with archives professionally simultaneously. The suggestion of village archiving in this study has the meaning that Korean archivists should get over the model of elite so that seek after new way of the going down to the archiving fields. village, community, the ordinance for the reconstruct of the beautiful village community, activistic archivist, archiving movement going down to the village fields, archiving by participation of community.

In the financial investment management strategy, the distributed investment selecting and combining various financial assets is called portfolio management theory. In recent years, the blockchain based financial assets, such as cryptocurrencies, have been traded on several well-known exchanges, and an efficient portfolio management approach is required in order for investors to steadily raise their return on investment in cryptocurrencies. On the other hand, deep learning has shown remarkable results in various fields, and research on application of deep reinforcement learning algorithm to portfolio management has begun. In this paper, we propose an efficient financial portfolio investment management method based on Asynchronous Advantage Actor-Critic (A3C), which is a representative asynchronous reinforcement learning algorithm. In addition, since the conventional cross-entropy function can not be applied to portfolio management, we propose a proper method where the existing cross-entropy is modified to fit the portfolio investment method. Finally, we compare the proposed A3C model with the existing reinforcement learning based cryptography portfolio investment algorithm, and prove that the performance of the proposed A3C model is better than the existing one.

Changes in a society and visual media has a tight relationship. Photography represented the last 20th century in the visual media; while the 21st century we live in is represented by moving image(video). The change of visual media also brought changes to the archaeological recordings. As information is gathered from the field work in archaeology, it seems that use of video recording, a reliable way of collecting and recording data, will increase. The process of archaeological excavations can be considered as a contents itself. Also, video recording has many advantages when recording environmental surrounding of the sites and artifacts, for the reservation of the scenery, and as recorded heritage of the humankind. Video recording can be a tool of conversion to public archaeology to devote to its social and academic roles. Considering all of the above, studying ways to record and preserve visual materials is essential in the field of archaeology and we should be prepared for it. We strongly propose reinstatement of the visual archaeology, which should be studied in archaeological perspective. The direction of the study of visual archaeology can be summarized into two. First is the study on the video recording during field work and the archive of video recordings. Second is the study on the media as the tool of communication. More detailed and organized research should be considered in depth in the archaeological theory and methods.

The purpose of this study is to closely analyze the case of blended-learning in order to provide a diverse and flexible learning environment while maintaining the nature of face-to-face classes, and to identify the learning environment that supports blended-learning in each class step and the educational experience of students. The experience and satisfaction of blended learning were investigated in various ways: course evaluation, LMS activity evaluation, and questionnaire before and after the class. As a result, the blended-learning is better than the traditional face-to-face classes, in providing real-time feedback, opportunities for various interactions, and textual conversations, anytime and anywhere. In addition, as a result of the preliminary survey, as a measure to solve the opinion that concentration was reduced due to problems such as networks and felt uncomfortable in the communication part, the theory and lectures of the design practice class were conducted non-face-to-face. The individual Q&A and feedback were conducted face-to-face and non-face-to-face. As a result of the follow-up survey, it was found that concentration and efficiency could be improved. This opens up possibilities for active use of the online environment in design practice classes.

Recently, IoT technology has been applied to various cloud environments, requiring accurate verification of various information generated by IoT devices. However, due to the convergence of IoT technologies and 5G technologies, accurate analysis is required as IoT information processing is rapidly processed. This paper proposes a blockchain-based multi-IoT verification model for overlay cloud environments. The proposed model multi-processes IoT information by further classifying IoT information two layers (layer and layer) into bits' blockchain to minimize the bottleneck of overlay networks while ensuring the integrity of information sent and received from embedded IoT devices within local IoT groups. Furthermore, the proposed model allows the layer to contain the weight information, allowing IoT information to be easily processed by the server. In particular, transmission and reception information between IoT devices facilitates server access by distributing IoT information from bits into blockchain to minimize bottlenecks in overlay networks and then weighting IoT information.

Cryptographic application and coding theory require operations in finite field $GF(2^m)$. In such a field, the area and time complexity of implementation estimate by memory and time delay. Therefore, the effort for constructing an efficient multiplier in finite field have been proceeded. Massey-Omura proposed a multiplier that uses normal bases to represent elements $CH(2^m)$ [11] and Agnew at al. suggested a sequential multiplier that is a modification of Massey-Omura's structure for reducing the path delay. Recently, Rayhani-Masoleh and Hasan and S.Kwon at al. suggested a area efficient multipliers for modifying Agnew's structure respectively[2,3]. In [2] Rayhani-Masoleh and Hasan proposed a modified multiplier that has slightly increased a critical path delay from Agnew at al's structure. But, In [3] S.Kwon at al. proposed a modified multiplier that has no loss of a time efficiency from Agnew's structure. In this paper we will propose a multiplier by modifying Rayhani-Masoleh and Hassan's structure and the area-time complexity of the proposed multiplier is exactly same as that of S.Kwon at al's structure for type-II optimal normal basis.
