The growth and development of Pygidiopsis summa were studied in experimental rats and mice, and a special reference was given to its morphological characters differed from the type species, P. genata. The metacercariae were obtained from young mullets (Mugil sp.), and total 21 rats and mice infected each with 1,000 metacercariae. Worms of various ages of infection, from 3 to 28 days, were subjected to a microscopic observation. The worms grew rapidly and remarkably in size up to 10 days of infection, to become 0.53~0.82mm long and 0.31~0.39mm wide, but nearly stopped the growth thereafter. Their genital organs developed more rapidly and fully matured within 3~5 days. At 3 days several eggs were found in uterus. The presence of two groups of small spines, 5~6 on the right and 7~9 on the left side of the genital apparatus, was a new finding in this study and considered a distinct character of P. summa. The morphology of ventral sucker and intestinal ceca was also different from P. genata. This study confirms the validity of the species, P. summa.

Cultural goods is carrying nature and value above-mentioned a commodity to what a cultural element was commercialized. And it produced for the purpose of manufacture for popular sales and supply, and holding commercial character. Specially, cultural goods of a museum keeps a good memory to a sightseer, and broaden an educational experience, and the source of profit becomes it to a seller a producer. This cultural goods as they all include the artistic historical figurative background that they are displayed directly and got twisted up to collection have background which became a motive. Cultural goods can acquire cultural difference in globalization and have to be based on the soil of cultural heritage, starting around various cultural materials through practical value to a modern life. Internationally, cultural goods using a culture material development have competitiveness of nation as in it. Therefore, Baekje cultural goods need national and positive aid from the government with the customer satisfaction index considering the modern design, an age group, an internal and external commodity as the difficulty of various commodity development and managing museum shop. Furthermore, like overseas museum shop, if we are practically using on-off line, continuous promoting our commodity, and marketing strategy such as a membership system when buy our cultural goods, a special discount event etc., we can contribute to activate local economy as a museum shop when we have responsibility of the function and the part.

Korea's film industry structure is focused on commercial movies centering on large companies, and its diversity and artistry are relatively overlooked. In addition to trends in the digital media age, the flood of consumable contents on the basis of special effects such as C.G, And is losing popularity as a popular art. The popular art should lead the mature social culture with the educational enlightenment character which induces the indirect experience and the wide insight of the world through the material and expression about the humanities study of the individual and the society. The analysis of the society's artistry and artistry about the movie "(2017)" can be a measure of the definition and kind of artistry in commercial movies and methodology about the manifestation of artistry. As a research methodology, we try to measure the future of the film industry by analyzing the status of the film as popular art, such as intellectual exploration and logical completeness of the essence of society, Through analyzing and criticizing the artistic characteristics in commercial films, I would like to suggest some improvement points by deriving the indicators of the artistic nature of commercial films. The film "1987" is a good example of an ideal commercial film with an artistry that cultivates cultural literacy, promotes civic consciousness through enlightenment messages, and plays a role of self-reflection through art experience. In other words, it shows the possibilities of commercial film with artistry in popular culture, such as a humanistic examination of true history and society, and an introspective gaze of the director expressed through the film society.

A nonlinear numerical method was developed to assess the stability of suspension bridge catwalks under a wind load. A section model wind tunnel test was used to obtain a catwalk's aerostatic coefficients, from which the displacement-dependent wind loads were subsequently derived. The stability of a suspension bridge catwalk was analyzed on the basis of the geometric nonlinear behavior of the structure. In addition, a full model test was conducted on the catwalk, which spanned 960 m. A comparison of the displacement values between the test and the numerical simulation shows that a numerical method based on a section model test can be used to effectively and accurately evaluate the stability of a catwalk. A case study features the stability of the catwalk of the Runyang Yangtze suspension bridge, the main span of which is 1490 m. Wind can generally attack the structure from any direction. Whenever the wind comes at a yaw angle, there are six wind load components that act on the catwalk. If the yaw angle is equal to zero, the wind is normal to the catwalk (called normal wind) and the six load components are reduced to three components. Three aerostatic coefficients of the catwalk can be obtained through a section model test with traditional test equipment. However, six aerostatic coefficients of the catwalk must be acquired with the aid of special section model test equipment. A nonlinear numerical method was used study the stability of a catwalk under a yaw wind, while taking into account the six components of the displacement-dependent wind load and the geometric nonlinearity of the catwalk. The results show that when wind attacks with a slight yaw angle, the critical velocity that induces static instability of the catwalk may be lower than the critical velocity of normal wind. However, as the yaw angle of the wind becomes larger, the critical velocity increases. In the atmospheric boundary layer, the wind is turbulent and the velocity history is a random time history. The effects of turbulent wind on the stability of a catwalk are also assessed. The wind velocity fields are regarded as stationary Gaussian stochastic processes, which can be simulated by a spectral representation method. A nonlinear finite-element model set forepart and the Newmark integration method was used to calculate the wind-induced buffeting responses. The results confirm that the turbulent character of wind has little influence on the stability of the catwalk.

Our nation have several procedures and law for national airspace management, however those procedures and law not enough to manage airspace. Therefore, I have studied this paper for improving flight safety and for providing economics flight of civcil aircraft and military aircraft, also, for increasing efficiency of airspace through systematic airspace management, additionally, for improving nation defense ability and for preventation our nation damage when occuring airspace problem. Nowaday. in using airspace. two theory which freely use theory and use theory under jurisdiction is opposed by every nation in worldwide. Consequently. we can realize every nation endeavour to increase their jurisdiction airspace. However. our nation is not still prepared to cope with other nation when occuring airspace trouble. because airspace definition is not prescribed on our aviation law. Therefore. several problems which are improved in our airspace management are presented on this paper. The presented matters are as follows. First, The airspace definition is not prescribed on aviation law and responsibility limit of airspace management is ambugious. Second. problem on structure of approach control area and special airspace, Third. problem on airway system. Fourth. civil agency and military agency apply respectively different regulation in establishment of aircraft flight route, To grasp these problems, considered the airspace conception, airspace classfication. legal character of airspace. our nation airspace state and management together with other nation airspace state and management. also compared our nation airspace management with other nation airspace management. And. improvement methods to solve problems which was appeared by comparing and analysis are presented on this paper.

Recently, school violence has come to the fore as a social phenomenon. "Comprehensive countermeasures for eradication of school violence" as a policy safety are created by Safety Administration bureau and Ministry of Education, Science and Technology under the chairmanship of the Office of Prime Minister on Feb,2012. This policy is supposed to be test-operated for a year from March, 2012. but voices of concern about effectiveness have been brought up by some critics greatly. So 172 teachers in high school in Seoul were surveyed in order to examine the effectiveness of "Comprehensive countermeasures for eradication of school violence" with a questionnaire composed of 5 point Likert-type. Among the fundamental measures, there were a total of 12 countermeasures about 'Practices for personality education' (with the exception of unrelated one question). 'Expanding opportunities of various art education and Supporting reading activities' of them ranked highest on average. Then, 'Reflecting results of special feature related to character develops to the Selection of Admission officers and Self-directed learning was the next. And among the three countermeasures about 'Reinforcement of roles of the family and society', 'Pan governmental conducting annual campaign related to broadcast, press, civic group to combat school violence was highest. Finally, among the 7 countermeasures about 'Countermeasure about harmful factors of games and internet addiction', 'Reinforcement of preventive discipline about game and internet addiction' was highest and 'Development and Promotion of various educational contents for preventive discipline about game and internet addiction' was the next.

Due to the explosive growth of the internet, terminology like "information society" and "virtual space" is frequently used, but often in a confusing manner. Some Social theorists and many people are fascinated by "information" and "media" as key characteristics of the contemporary world and rely on the unproven opinion that "Knowledge is a source of value and information moves the world". In this regard, Boudllian defines contemporary culture as a culture of signs and insists that we are surrounded by signs and forms of meaning. There isn't anything behind the signs but signs only exsist, so we cannot escaped from its inauthenticity and consider it improper to insist on it. If people can understand that signs are just simulation of reality, that would be alright. But in fact anything cannot be alright.In this matter Boudllian's conclusion is that we produce images in bulk which are not worthy seeing. Today we reach the conclusion that most images are the letter(character) image itself which shows nothing special.Consequently, this kind of world is a postmodern-world that seems meaningless but has signs to experience and enjoy, many examples of which are shown in the media, such as the internet. We can get to the conclusion that the audience neither sees nor hears anything, but they just can experience many interesting things which characterize the present age. The purpose of this research is to help you to understand current design philosophy and the direction of media while considering both a positive social phenomenon about the new design paradigm of information and media, as well as critical thinking about it.

The Miaos who is the minority people mainly living in the southwestern part of China, expressed their indicator and solidarity through the costume in order to maintain their racial character while experiencing numerous adversities over thousands of years, where the costume has served as a source of cohesion as well as a primitive religious thought, and also showed their faith, desire, longing and aspiration. This study examined the Miao's traditional costume by classifying it into the following; hair style, headdress, upper and lower garments, and other costume. And the silver ornaments used for attire and their symbolic meaning were examined. The result of the study is summarized as follows. 1. The reason that types of the costume has been diversified is because there was promise of ancestors who intended to differently express the type of a kind as symbol of the racial branch that is the Miao's special type of society. Thus, the costume type could tell where a tribe live. Another reason is because only marriage between families with different surname but the same type of costume was accepted. 2. As women made and wore the costume themselves, it also served as a means of being proud of their skill or wealth, they tried to make it more beautiful and it was also used as a token of marriage or love between relatively enlightened men and women. 3. The design used on the costume was expressed as a symbolic meaning of indicator to strengthen the racial solidarity because it connoted worship to ancestors who had experienced lots of adversities. 4. The hair style was expressed in various styles by using Kache such as Chukye, Byunbal and Kokye. It is likely that ornaments used on the head of women in the form of cow's horn or silver crown were used as one of the methods to stress the valuableness of the cattle that were essential to agricultural life. In addition, various styles of turbans were used to indicate the respective regions. 5. Cock's feather ornaments or silver ornaments in the form of pheasant's feather on the edge of women's skirts, peasant's feathers that men wore on their head, or Baekjoui and men wore resulted from the Miaos' thought of adoration for birds, which implied a primitive religious meaning. 6. As the region where the Miaos live yields much silver, the silver ornaments were mostly used to be proud of wealth, which symbolized light and pureness.

The purpose of this paper is to design, implement and test the automatic marking system for programming languages using key-words and boolean operations to solve the processing problems of natural languages. There are accurate grammar systems and key-words in programming languages. Using these characteristics, We have designed, programmed, and tested automatic marking system for programming languages through key-words and boolean operations in this paper. We have categorized programming languages into 7 types as the type of answer and when a professor input any key-words, the system make him put conjunction with the special character. It can be logical expressions instantly so that the system easily operates. We asked 10 students who are majoring in computer engineering to take a test on the paper and web to show how well automatic marking system that we have programmed works. Then We requested 3 professors if the subject problems marked objectively. As a result, automatic marking system proved to be appropriate. We have proposed the way of using key-words and boolean operation for prohibiting huge natural language processing in marking of subjective question. It promotes efficiency rate of programming, objectivity and speed through the transferal to the web for marking since the system prohibits marker to include personal opinion on marking and gives feedback quickly
