The purpose of this study was to analyze responses as bystanders of middle school girls in a simulated cyberbullying situation. This study also aimed to examine effects of bullying, victimization, anger-out, and state-anger on responses from girls as bystanders. The participants were composed of 2nd or 3rd grade middle school girls(N=59). Responses were classified into 7 categories(using explicit language, attacking, pass, changing topic, comforting victims, others, and conformity). Of these, attackings were classified according to the target(bully, victim, both, and ambiguous object). It was again classified as 'attacking response' and 'helping response' and was scored and summed according to the strength of the response and used as a dependent variable. Collected data were analyzed by correlation analysis and multiple regression analysis. The results of this study are as follows: First, the most frequent response was 'the others'(41.69%) followed by 'using explicit language'(20.34%), 'passing'(13.56%), 'attacking bully'(8.81%), 'conformity'(8.64%), 'changing topic'(6.61%), and 'comforting victim'(0.34%). Second, responses of attacking victim were positively influenced by the previous bullying experiences and acting anger-out, and were negatively influenced by the previous victimization experience. State-anger has a positively influenced on responses of the attacking bully and the helping victim. None of the variables were significant influenced on responses of the attacking both and ambiguous object. These results will be useful data to help middle school girls as bystanders properly intervene in cyberbullying situation. Finally, the limitations of this study were discussed along with suggestions for further research.

The article considers the fundamentalization of education in improving the future specialists professional training with usage of multimedia technologies by various scientists. Various points of view and approaches to defining the concepts of fundamentalization of education and multimedia technologies are identified. The concept of fundamentalization of professional training of a future specialist is based on the goals and functions of fundamentalization and - on the ways and means of achieving it, etc. Most authors agree only in their views that the fundamentalization of education is aimed at improving the quality of education and the education of the individual. Others involve the formation of a culture and worldview, increasing the creative and intellectual potential, forming the professional competence of a specialist and the potential for further education, and so on. The term multimedia refers to interactive systems that provide processing of moving and still video images, animated graphics, high-quality audio and speech. It is found out that professional training of a specialist by means of multimedia technologies includes not only the activities of the teacher and student, which form the learning process, but also the independent activity of the subject, self-development, assimilation of experience by the subject through analysis, comprehension and transformation of the field of activity in which he is included. It is revealed through the implementation of which approaches to the fundamentalization of higher professional education, it becomes possible to fully present theoretical training courses and effectively pass practical training by students, which contributes to improving the quality of training of future specialists in higher education institutions. Theoretical analysis of scientific views indicates a fairly serious attention of scientists to the problem of professional readiness of specialists and the possibility of higher educational institutions in preparing for it. At the same time, professional readiness is considered from different positions: as an active state of a person, which manifests itself in activity; as a result of activity; as goals of activity; as a quality that characterizes the attitude to solving professional problems and social situations; as a prerequisite for purposeful activity; as a form of activity of the subject; as an integral formation of personality; as a component of socio-professional culture; as a complex professionally significant neoplasm of the individual.

In Korea, which is entering a super-aged society, the number of elderly patients who have difficulty walking independently is expected to increase rapidly, and it is necessary to develop wheelchair products with various functions to improve the quality of life of people with walking disabilities. Recently, wheelchair power assist devices that provide propulsion power by being attached to a manual wheelchair has been developed and is entering the domestic and global markets. In this study, we compared and analyzed the process of obtaining medical device certification for wheelchair power assist devices in Korea, the United States, and Europe. In Korea, a Class 2 medical device certification process was developed in 2021, and in the US FDA, it corresponds to Class 2 like the existing electric wheelchair and must pass the 510k certification process. In the case of Europe, it is uniquely regulated as Class I, and the CE mark can be attached through a relatively easy self-declaration of conformity. The Korean medical device industry, which is struggling with MDR certification, a new European medical device regulation, should pay attention to the relatively easy entry into the global market for wheelchair power assist products.

This study was conducted to investigate the effects on fermentation characteristics of rumen microorganism by different types and levels of lignosulfonate treated soybean meal (LSBM) in in vitro test and rumen simulation continuous culture (RSCC) system in dairy cows. The experiment I was control and 12 treatments (each with 3 replications) in vitro test to demonstrate composition of different types of treatments with lignosulfonate (Desulfonate, Na, Ca and solution) and levels (2, 4 and 8%) of soybean meal in the dairy cow diet. LSBM source treatments in the dairy cow diet showed pH value, $NH_3$-N concentration and total VFA concentration lower than control at all levels and incubation times (p<0.05). Dry matter digestibility of LSBM source treatments showed lower than control (p<0.05). Gas production and rumen microbial synthesis was decreased by rumen microbial fermentation for incubation times. Undegradable protein (UDP) concentration of all LSBM treatments was decreased for incubation times, and significantly higher than control (p<0.05). In the experiment II compared diets of the control, LSBM Na 2%, LSBM Sol 2%, which are high performance to undegradable protein (UDP) concentration experiment I in vitro test, and heated treatment lignosulfonate (LSBM Heat) 2% in the dairy cow diet from four station RSCC system ($4{\times}4$ Latin square). A rumen microbial fermentation characteristic was stability during 12~15 days of experimental period in all treatments. The pH value of LSBM treatments was higher than control treatment (p<0.05). The $NH_3$-N concentration, VFA concentration and rumen microbial synthesis of LSBM treatments were lower than control (p<0.05). The undegradable protein (UDP) showed LSBM Na 2% (45.28%), LSBM Sol 2% (43.52%) and LSBM Heat 2% (43.49%) higher than control (41.55%), respectively (p<0.05). Those experiments were designed to improve by-pass protein of diet and milk protein in the dairy cows. We will conduct those experiments the in vivo test by LSBM treatments in dairy cows diet.

From the end of the 18th century to the end of the 19th century, the late 19th century was a genre of a new art that was in contrast to the distribution between social class and low class, and it was also a popular culture that attempted to transform the late Joseon Dynasty's social class. It is no exaggeration to say that it is the origin of the Korean folk art, started as popular art concepts, use colorful techniques and decorations which doesn't yield to ordinary iconography. But, because of the attempt of this technique was used by lower class, the meaning of the idea was lowered from iconography to secular picture. Ethics character picture, passed on to the present from going through the upheaval cultural time, was started from secular picture and transformed into hyukpil time illustration, and it represented popular arts until now. This thesis aims to reflect the meaning, various visual expressions and the lifestyle of Ethics Character Picture of filial piety and brotherly love, which is a unique genre of popular arts. Also, propose to suggest about the kinetic typography using video media, and how the traditional ethics character picture, which are combined with video technology, effects to the advertisements. These kind of attempts will show the world about the korea's traditional contents, and through the various media information it can be recreated as national symbolic key words. Furthermore, its meaningful to pass down the noble and cultural Ethics Character Picture of filial piety and brotherly love to younger generations. And by realigning to modern expression, it is predicted that it will be significantly meaningful to pass down and make the younger generations to understand to spirit of the ancestors. This will allow various attempts to reconstruct various items of contents from Korea's traditional contents to new media content that merged with video media.

An in vitro study on cariogenic potential of 8 over-the-counter syrups for children was performed. The experimental groups were 8 over-the-counter syrups. The positive control group was 10% sucrose solution, and the negative control group was artificial saliva. The pH of each group was determined. The buffering capacity was measured by the volume of 2 N NaOH adding to equalize the pH of 20 ml of experimental solution to pH 7. The consistency was measured by the time to pass Ostwald pipette for 2 ml of the experimental solution. The experimental solutions were inoculated with S. mutans and cultured in $37^{\circ}C$ anaerobic condition for 48 hours. To estimate acid production, pH of the experimental solutions were measured before and after the culture. The primary teeth specimens were soaked in the experimental solutions for 20 minutes three times a day. Except on those hours the specimens were stored in artificial saliva. After 5 days, the microhardness changes of the specimens were measured. These results show that most of syrup-form medicines for children tend to have cariogenic potential partially in endogenous pH, buffering capacity, consistency, acid production and erosive ability of enamel. For the oral health of children, the alternative sweeteners (ex. xylitol) may be substituted for the cariogenic sweeteners of syrups. Additionally, It may be helpful that the chewable tablet replace liquid or syrup in term of dose form.

During the boom of museum building in the 1970s-80s two museum wee erected in Germany. They are James Stirling's Neue Stattsgalerie Stuttgart and hans Hollein's Stadtisches Museum Abteiberg Monchengladbach, These two museums share the folowing point of similarity : Stirling's Neue Stattsgalerie Stuttgart and Hollein's Staditisches Museum Abetiberg Monchenbladbach both manifest the conditions of the times in light of their respective cities' local characters and historical contexts without being bound to traditional formality. Stirling and Hollein attempted to grasp the meaning of the 기nuseum as a city in miniature." Taking into account the t two museums’s territorial characteristics of being situated on a slope, both Stirling and Hollein made the walker to pass t through their building complex and introduced the concept of a public square within them. As a result, the museums are not j just two large buildings but are architecture composed of a collage of various structures. S Stirling’s architecture employs the method of attaching additional elements on top of basic constituents, which is suggestive '||'&'||'#61551; of the historical fragment from Shinkel's Altes Museum. On the other hand, Hollein applies a collage-style method as if he w were doing urban planning, maintaining the distinctiveness of each of the various forms and materials of buildings. T The object style buildings of the two museums actively demonstrate the contrast of double meaning to represent the a ambiguous and multifarious characteristics of the modern times. Stirling explores the theme of opposition and coexistence in h his Neue Stattsgalerie Stuttgart by placing a series of opposing concepts, such as the past and present and histor${\gamma}$ and t technology, in one space. Thereby, the contradiction and its appeal are manifested. Hollein made use of the visual illusion and c contradiction in alluding to the irony of the modern reality induced by nature and culture and history and technology. F For the above reasons and methods, James Stirling ’ s Neue Stattsgalerie Stuttgart allowed the penetration of art into daily l life and became the general public’s favored museum for its free and unrestrained environment. Likewise, Hans Hollein’s S Stadtisches Museum Abteiberg Moncbengladbach contribute to the development of museum function as it an expression of art i in the form of a complex piece of scupture on its own.ts own.

In International trade the buyer and seller are normally separated from on another not only by distance but also by differences in language and culture. It is rarely possible for the performance of obligations to be simultaneous and the performance of contracts therefore calls for trust in a situation in which the parties are unlikely to feel able to trust each other unless they have a longstanding and successful relationship. Thus the seller under an international contract of sale will not wish to surrender documents of title to goods to the buyer until he has at least an assurance of payment, and no buyer will wish to pay for goods until he has received them. A gap of distrust thus exists which is often bridged by the undertaking of an intermediary known and trusted by both parties who will undertake on his own liability to pay the seller the contract price in return for the documents of title and then pass the documents to the buyer in return for the reimbursement. This is a common explanation of the theory behind the documentary letter of credit in which the undertaking of a bank of international repute serves as a "guarantee" to each party that the other will perform his obligations. The independence principle, also referred to as the "autonomy principle", is at the core of letter of credit or bank guarantee law. This principle provides that the letter of credit or bank guarantee is independent of the underlying contractual commitment - that is, the transaction that the credit is intented to secure - between the applicant and the beneficiary ; the credit is also independent of the relationship between the bank and its customer, the applicant. The most important exception to the independence principle is the doctrine of fraud in the transaction. A strict interpretation of the rule that the guarantee is independent of the underlying transaction would lead to the conclusion that neither fraud nor manifest abuse of rights by the beneficiary would constitute an objection to payment. There is one major problem related to "Independent guarantees", namely abusive or unfair callings. The beneficiary may make an unfair calling under the guarantee. The countermeasure of beneficiary's unfair calling divided three cases. First, advance countermeasure namely by contract. In other words, when the formation of the contract, the parties must insert the Force Majeure Clause, Arbitration Clause to Contract, and clear statement to the condition for demand calling. Second, post countermeasure namely by court. Many countries, including the United States, authorize the courts to grant an order enjoining the issuer from paying or enjoining the beneficiary from receiving payment under the guaranty letter. Third, Export Insurance. For example, the Export Credit Guarantees Department is prepared, subject to certain conditions, to cover the risk of unfair calling. Of course, KEIC in Korea is cover the risk of the all things for guarantees. On international projects, contractor performance is usually guaranteed by either a standby letters of credit or Independent guarantee. These instruments will be care the parties.

This research has the purpose to approach 'Audience participation theatre' through applying the concept of 'Hybrid' which newly come to the fore after 21st in a theatre space. In fact, 'Hybrid' has been suppling crucial power to create and pass a culture down for a long time, and it could not different to a theatre space. The hybridity in previous traditional theatre which is central 'text' and 'architectural theater' is limited movement only on the stage, such as 'an actor between presence and absence', 'a theatrical time between real and fiction' and 'an objet between An Sich(thing itself) and Fur Sich(thing with inner meaning). However after 20st's 'Avant-Garde' with 'decomposition sprit', the hybridity become broader from only on the stage to entire theatre space including auditorium caused by collapse the boundary between auditorium and stage. In other words, 'auditorium' and 'audience' are considered as 'a theatrical element' coequal with other elements, and it can create various special results through they are mixed equally. Therefore, 'Audience participation theatre' could regarded a kind of hybrid phenomenon between 'auditorium and audience' and 'actor and stage' which are most disparate relation, and it is also approached 'hybridized audience', 'hybridized space' and 'hybridized text' as a new identity.
