A pavilion is located in the place with beautiful scenery, which maximizes the poetical features of nature. So a scholar in the Chosun Dynasty had the dream of possessing it. This trends of the Chosun scholar resulted in producing lots of literary works related with the pavilion. In this thesis, I researched the characters of Pavilion Si-Jo in accordance with the function of pavilion. First, the pavilion, which is surrounded by the beautiful scenery, is a good place to see the beauty of nature. It is needless to walk around to see the scenery thanks to its open structure. So the feeling in the pavilion Si-Jo is distinguished from other sightseeing Si-Jos: those show the way of seeing the scenery walking here and there, but this shows the way of seeing the scenery only just looking up, looking down, and looking in the distance. Second, the pavilion functions as an academic place. In this case, it can be said that it functions like a lecture hall. It is more effective to study in the pavilion than in the closed structure, a lecture hall. Furthermore, the scholar studying in the pavilion understand the principle of nature with seeing the beautiful mountain and river, and it can be a place for growing a vast-flowing spirit. This kind of poetry has been handed down with the Chinese poetry, and the character who operated the pavilion often appears in the work. Third, the pavilion functions as a space for a fraternity or poetry circles. The poetic exchange was conducted by host of pavilion. which is the key ingredient for organizing a poetry circles. Finally, the pavilion functions as an entertainment. Although it is a space for an entertainment, there is no deviation as a man of novel birth. If the pavilion has the feature of closeness, there are sometimes works which shows the deviation of them.

Due to the advent of ubiquitous computing environment, it is becoming a part of our common life style. And tremendous information is cumulated rapidly. In these trends, it is becoming a very important technology to find out exact information in a large data to present users. Collaborative filtering is the method based on other users' preferences, can not only reflect exact attributes of user but also still has the problem of sparsity and scalability, though it has been practically used to improve these defects. In this paper, we propose clustering method by user's features based on SOM for predicting purchase pattern in u-Commerce. it is necessary for us to make the cluster with similarity by user's features to be able to reflect attributes of the customer information in order to find the items with same propensity in the cluster rapidly. The proposed makes the task of clustering to apply the variable of featured vector for the user's information and RFM factors based on purchase history data. To verify improved performance of proposing system, we make experiments with dataset collected in a cosmetic internet shopping mall.

The medical drama has developed into a story centered on 'people', raising viewers' sympathy. The story of the drama is the true life story of doctors, patients and families. It is also a story that reminds me of 'a little special day of our ordinary people'. And the song played and sung by five characters in the drama became a factor that stimulates nostalgia and increases immersion. The highest viewer rating was 14.1%, and 51,584 blogs alone were registered. According to the big data analysis, the related words were 'Wise OST', 'Album Name', 'Artist Name', 'Two Hours in a row', 'Record', 'Remake', 'OST Revealed', 'Advertisement Revenue', 'Playlist', 'Aroha' and 'Cho Jung-seok'. The commercialization of medical dramas includes 'Sales of Drama OST Albums', 'Organizing Online Live Concerts (PPL in Advertising)', 'Publishing Piano Music', 'Picture of People-Oriented Photography', 'Making Music Video Editing Drama Highlight', 'YouTube Upload Profits', 'Mask' and 'Disinfectant'. it is predicted that the touching story of Corona 19 and the charming humanity will unfold. The limitations of the research will require analysis of various works by genre and attempts to analyze consumer values by industry.

This study analyzed the educational contents related with child's human rights in a manual of the Nuri Curriculum for 5-year-olds based on the type and area of activity, 5 areas, and by life theme. The research results are as follows: First, the educational contents on child's human rights in activity type and area showed high frequency in the order of large and small group activity, child selected play activity, and outdoor activity, and among them, right to an education and right to play showed the highest frequency. Second, among the five categories, the area that conducts educational contents on child's human rights was the social relation category, and the area that showed the highest participation was the educational contents on human rights. On the other hand, the areas that were treated the least were physical activity and health. Third, the topic that treated the educational contents related with child's human rights was 'spring, summer, fall, winter,' and 'my family and I' treated educational contents on child's human rights in the lowest frequency. Also, whereas the right to education and right to play showed the highest frequency of educational contents on child's human rights among entire life themes, the educational contents on child's human rights of abuse and neglect(violence) were not treated at all in the entire life themes. Through the results of this study, it will be helpful in planning and deploying activities related with the child's human rights harmoniously, and intends to provide important basic data in organizing activities of human rights program linked with the elementary school.

The objective of this study was to determine the microtubule assembly and chromatin configuration during the first cell cycle in bovine oocytes following injection of spermatozoon, sperm head and tail. The microtubule and chromatin configuration was imaged with fluorescent labeled monoclonal ${\alpha}$-tubulin antibody and propidium iodide under laser scanning confocal microscope. Microtubule and chromatin dynamics in bovine oocytes following intracytoplasmic sperm injection (ICSI) were not different from those observed during in vitro fertilization (IVF). Following ICSI, the microtubular aster was observed around sperm midpiece. During pronuclear formation, the sperm aster was enlarged and seen around male and female pronuclei. At mitotic metaphase, the microtubular spindle assemble astral poles and chromosomes were aligned on the spindle equator. At mitosis, asters were concentrated to each spindle pole and they filled the cytoplasm. After injection of the isolated sperm head, the microtubular aster was not seen around sperm head in any cases (0/18). Instead, microtubules were organized from the cytoplasm, which filled the whole cytoplasm during pronuclear apposition. These microtubules seem to move male and female pronuclei. These results suggest that isolated sperm head can develop into normal pronucleus in mature bovine oocytes, and competent to participate syngamy with the ootid chromatin. The functional microtubules following isolated sperm head injection in bovine oocytes appeared to be organized solely from maternal stores.

The main purpose of this thesis is to research various theories in Cultural Education. It is to rebuild the value of home economics, and to demonstrate its potential to bring out a true human being. Until now, home economics education had been focused on developing ability to solve problems, only to fail us in training students to have ability to cope with different conditions in daily life by themselves. With the society rapidly changing, such a temporizing education system would lose its value immediately, and the identity of home economics education is at stake today. The present situation is resulted from the failure in approaching the culture education properly. With the fact that the elements of home economics are culture themselves. the failures in organizing and teaching the subject would urge us to rearrange curriculum of home economics. We need to bear in mind that the curriculum of home economics cannot contain every cultural value. A careful consideration is necessary in order to include the essence of the culture at the minimum quantity. Through analyzing different types of theories and methods of education in Cultural Education, this research is aimed at reviewing home economics education with its concept. Further study in the future should be proceeded with more comprehensive researches on instruction and learning methods with Cultural Education perspective, based on the analysis.

This paper aims to examine the ways in which project-based organizations (PBOs) are embedded in social networks and geographical clustering in the case of TV drama industry. PBOs refer to a variety of temporary organizational forms for the performance of tasks as to integrate diverse and specialized intellectual resources. PEOs as a flexible and innovative mode of organizing knowledge resources are becoming increasingly worthy of attention in emerging the creative economy. Evidence from interviews with core persons of PEOs like producers, directors, and writers reveals that the key operational mechanism of the project form of organization is based on the highly socialized networks via individual's reputation and past experiences. In other words, the project activity in TV drama is embedded in networks which are socially constructed. Also the geographical clustering plays an important role in PBOs and project practices in TV drama are constructed around a high degree of spatial clustering. PBOs are clustering in Kang-nam and Yeouido, where are located in independent production companies and broadcasting stations. It means that the project formation in TV drama requires geographically-clustered networks of human resources, and socially, culturally and geographically embedded latent networks of interpersonal relationships are a necessary condition of POBs in the TV drama industry.

Korean language has the characteristics that the pronunciation of phoneme units such as vowels and consonants are fixed and the pronunciation associated with a notation does not change, so that foreign learners can approach rather easily Korean language. However, when one pronounces words, phrases, or sentences, the pronunciation changes in a manner of a wide variation and complexity at the boundaries of syllables, and the association of notation and pronunciation does not hold any more. Consequently, it is very difficult for foreign learners to study Korean standard pronunciations. Despite these difficulties, it is believed that systematic analysis of pronunciation errors for Korean words is possible according to the advantageous observations that the relationship between Korean notations and pronunciations can be described as a set of firm rules without exceptions unlike other languages including English. In this paper, we propose a visualization framework which shows the differences between standard pronunciations and erratic ones as quantitative measures on the computer screen. Previous researches only show color representation and 3D graphics of speech properties, or an animated view of changing shapes of lips and mouth cavity. Moreover, the features used in the analysis are only point data such as the average of a speech range. In this study, we propose a method which can directly use the time-series data instead of using summary or distorted data. This was realized by using the deep learning-based technique which combines Self-organizing map, variational autoencoder model, and Markov model, and we achieved a superior performance enhancement compared to the method using the point-based data.
