Cyberbullying has become a critical issue as people (especially, young people) daily use social networking sites (SNSs). This study investigates possible factors affecting cyberbullying victimization experiences, comparing SNS users in Austria and Korea. Particularly, this study focuses on how individuals' self-disclosure patterns, compulsive Internet use, and depressive status are related to four different types of cyberbullying victimization experiences (written-verbal, visual, exclusion, and impersonation). Furthermore, the results are compared between SNS users in Austria and Korea. Results from total 519 respondents show that self-disclosure patterns on SNSs, compulsive Internet use, and depressive status are positively related to different types of cyberbullying victimization experiences. However, there are differences between Austria and Korea. For example, the frequency of changing one's profile setting is positively related to all types of cyberbullying victimization experiences in Korea, while it is only positively related to victimization experience of visual cyberbullying in Austria. Depressive status is only positively related to victimization experience of written-verbal cyberbullying in Korea, while it is positively related to all types of cyberbullying victimization experience in Austria.

The subjects of analysis in this paper, the clan name roots "Baj," "Kim," and "Shama/Sama," while distributed commonly among the Altai, Ye i, and isolated language groups, are most widely distributed among the Evenki. The clan name root "Baj-" is widely distributed among indigenous Siberian nations, but is most frequently found among the Manchu-Tungus, especially the Evenki. Therefore, it appears that clans with this root originated from Pribajkal'e, known to be the origin of the Evenki, and spread widely among the nearby Buryats, Mongols, and Yakuts, later spread east to the Nivhi of the Amur River, to the Enisej Protoasiatic language nations such as the Yukaghir or Ket to the north, and the Samoyed language group nations such as the Ne and Selkup. According to the analysis results in this paper, the Evenki clan name "Kim" has the meaning of "person," but also is somewhat associated with gold, metal, or stone. On one hand, while the origin of the clan name "Kim" cannot be clearly established, the clan was assimilated into the Evenki near in ancient times, after which the clan name became widely known among the Manchu-Tungus nations, and furthermore in the Turk nations. The clan name Shama/sama is widely spread across Siberia, including the Manchu-Tungus language group nations of the Altai language family, the Turk language family, and the Samoyed language groups of the Ural language family. Moreover, this clan name is not associated with famous mythic ancestors or heroes of historically famous Asian nations, and it cannot be translated into contemporary language; thus the identification of the meaning and origins of this word is by no means an easy task.

ZnS:Cu,Cl 형광체의 여기 및 발광 스펙트럼 측정 결과 주게인 $Cl^-$ 이온과 받게인 $Cu^+$ 이온 사이의 흡수와 발광에 기인하는 peak과 국소화된 발광 중심인 $(CU_2)^{2+}$ 이온의 흡수와 발광에 기인하는 peak이 관측되었다. CuCl의 첨가량이 증가함에 따라 $Cu^+$ 이온의 농도가 증가하게 되어 $(Cu_2)^{2+}$ 이온에 기안하는 발광으로부터 공명 에너지 전달 (Resonant Energy Transfer)의 확률이 높아지기 때문에 513 nm를 중심으로 하는 발광의 세기가 증가하게 된다. 자체 제작한 ZnS:Cu,Cl 형광체를 이용하여 제작한 소자의 휘도 측정결과 400 Hz, 100 V 에서 CuCl 의 첨가량이 0.2 mole% 일 때 휘도가 최대였고, 진동수가 증가함에 따라 휘도가 포화되는 현상이 나타났다. CuCl의 첨가량이 증가함에 따라 513 nm를 중심으로 하는 발광이 강해지고 CIE 좌표값이 녹색영역으로 이동하게 된다. 진동수가 증가하면 인가된 전압의 유지 시간이 짧아지게 되어 발광의 감쇄시간이 긴 513 nm를 중심으로 하는 발광보다 감쇄시간이 짧은 458 nm를 중심으로 하는 발광이 강해지게 되고, CIE 좌표값이 청색영역으로 이동하게 된다.

The purpose of this study is to investigate knowledge structure of knowledge organization research area in Korea. The study employed content analysis and network analysis to analyze degree centrality, betweenness, and eigenvector as well as frequency of words. It also analyzes research articles published during the period of 2000-2001. The study can be summarized that the network of keywords of knowledge organization researches is compact and complicated. Cataloging and classification play important roles in the network, and metadata and ontology becomes focal areas in knowledge organization. On the other hand, networks of authorships and authors are broad and fragmented. Collaboration is not active enough.

This study, which works to develop a method of focusing on A Quiet Dream by Zhang Lu, explored the structural differences of films and the changes in Zhang Lu's aim and perspective as noted in films, by a review to grasp his internal changes in texts and contextual factors. In A Quiet Dream, Zhang Lu made a filmic attempt that had never been made in the world of films prior to that date. He tried an aesthetic experiment on how films could reorganize the world, by using the effect of obscuring the boundary between reality and dream in films and generating a new narrative regarding filmic reality, actual reality, and the life and artistic truth of the Diaspora. Generally speaking, the changes in the narrative in A Quiet Dream seem to be his resistance against himself and the Diaspora. Thus, in the discussion about A Quiet Dream, relying on the external factors intervening in the relationship between the subject of creation and films is not a useful endeavor at this time. Consequently, it is noted that after settling down in Korea, Zhang Lu could directly approach the changes in the cultural position of films in multilayered ways, where films were the most dynamic part of his life. Due to the changes in the Diaspora, he could obscure the boundary for the first time in the world of films and experiment with how films could escape develop an interesting perspective that deviated from reality, and made a new goal to show new ideas regarding the individual's awareness of the world.

This study empirically analyzed the factors affecting the intention to utilize manufacturing AI in SM-sized manufacturers by applying the TOE framework. Independent variables that are expected to influence were applied, focusing on TOE factors and managerial characteristics that reflect the characteristics of SME manufacturers. In addition, the mediating effect of technology trust and the moderating effect of factory location were analyzed. The results are as follows. First, the relationship between the independent variables and the dependent variable was tested, and the direct effects of the independent variables(complexity, organizational innovation, IT ability, competitive pressure, partner support, and managerial innovation) on the dependent variable were all statistically significant, except for compatibility. Second, the mediation effect of technology trustness was verified to have a full mediation effect between compatibility and utilization intention, and a partial mediation effect between managerial innovation and utilization intention. Third, among the seven independent variables, the moderating effect of factory location(metropolitan and non-metro) between the three independent variables of IT ability, competitive pressure, and partner support and the utilization intention was found to be significant. To increase the intention to utilize manufacturing AI for SM-sized manufacturers, it is recommended that more diverse and broader studies are needed, not only the factors identified in this study, but also the understanding and awareness of manufacturing AI.

This study examined mathematics class using the CAS(Computer Algebra Systems, CAS) targeted for high school first grade students. We examined what kind of transforming of representations got up according to mathematics subject contents at this classroom. This study analyzed 15 math lessons during one month and the focus of analysis was on the classroom teacher. In particular, for transformations among representations this study mainly investigated from theoretical frameworks such as transparent and opaque representation of Lesh, Behr & Post(1987), descriptive and depictive representation of Kosslyn(1994). According to the results of this study, CAS technology affected the transforming of representations in high school math class and this transforming of representations improved the students' thinking and understanding of mathematical concepts and provided the opportunity to create the representation of individual student. Such results of this study suggest the importance of CAS technology's role in transforming of representations. and they offer the chance to reconsider the fact that CAS technology could be used to improve students' ability of transforming representations at the mathematics class.

Recently, it is more important to do part of software designers for developing user-centered software. They produce visual document for helping communication between developers and visual diagram for analyzing user need factors based on user scenario. Case study of architecture real dispatch service can show developing samples. It is important to produce visual document for one combined opinion between developers in process of defining of development boundary, main concept development, selecting of development system. And visual document process with visual language by software designer is step for recognizing of user need factors before developing interface design in process of collecting design factors of user and environment and analyzing design factor by user scenario. Also, in process of interface and prototype development, it need visual document for peaceful and concord process between developers. Those visual documents with visual language could help to define developers role and duty, user-centered concept development and various interface development proposal during software developing.

In order to develope high concentration$\cdot$yield ozonizer, superposed discharge type ozonizer using overlap of silent discharge and internal electrode of mesh type has been designed and manufactured. It consists of three electrodes(central electrode, internal electrode and external electrode) and double gaps(gap between central electrode and internal electrode, gap between internal electrode and external electrode). Therefore, ozone is generated by overlapping silent discharges generated between the gaps respectively for which the AC high voltages applied to the internal electrode and the external electrode has a $180{[^\circ]}$ phase difference and for which the central electrode is a ground Ozone generation characteristics proportional to mesh of internal electrode by increasing of discharge electrode and controlling of discharge power density. As a result, the in maximum ozone concentration, generation, and yield can be obtained 17,720[ppm], 5.4[g/h], and 205[g/kwh] respectively.

In "The Animal That Therefore I Am (More to Follow)," Derrida notices that he is being watched by his cat. He becomes ashamed of being naked in front of his cat. The sense of shame is a response to being reduced to the level of an animal. He is ashamed of being as naked as an animal. His next move is, therefore, to cover his nakedness from the gaze of his cat. By contrast, he realizes, the animal is not self-conscious of being naked and so does not shield its nudity. In a truer sense, then, the cat is not naked. Humans do not see animals for what they really are but what they project on them. Whereas the gap between man and animal is clearly identified by Derrida's philosophical discourse, the possibility of going beyond the gap can be suggested by fantasy stories in children's literature. Children's literature in Britain arose in the eighteenth century with the revival of traditional fairy tales and growth of literary fairy tales. Romanticism in the early nineteenth century contributed to opening up a new horizon for the concept of the child, in which the child is no longer defined as the object to be tamed and childhood imagination is glorified as a powerful means to reach the higher state, the spiritual origin prior to separation of Man from the 'thing-in-itself.' In The Wind in the Willows, animals talk and behave like humans. The anthropomorphic figuration of animals can be understood as a result of the one-sided projection of anthropocentric perspectives on animals rather than an interaction between humans and animals. Significant contradictions also emerge in this story, however, as traits particular to animals are vividly delineated even as the main didactic theme of good triumphing over evil reflects an anthropocentric projection on animals. An attempt to capture the true characteristics of animals and locate them in the text constitutes a remarkable achievement in The Wind in the Willows. This can be evaluated as an important step toward a more ecopocentric perspective on animals which appears in later children's fantasies like Charlotte's Web.
