This experiment was carried out to order to determine the forage production and soil characteristics in mixtures of Italian ryegrass (IRG) and annual legumes at the riverbed. The IRG and hairy vetch mixture had the highest in fresh, dry matter (DM) as well as total digestible nutrients (TDN) yields among the forage mixtures. Further IRG and hairy vetch mixture had the highest in DM content. The crude protein (CP) content of IRG and hairy vetch mixture was the highest, Whereas non-fiber carbohydrate (NFC) and TDN contents were lower compared to other mixtures. The total nitrogen (TN) of IRG and hairy vetch mixture was the highest due to high nitrogen fixation in the riverbed soil. The IRG and rape mixture was the highest in organic matter (OM) of soil. Moreover, the available $P_2O_5$ of soil in IRG and crimson clover mixtures was higher compared to other mixtures. Further, the IRG and hairy vetch mixture was the highest in cation exchange capacity (CEC) content. Therefore IRG and hairy vetch mixture is more suitable in forage mixtures due to high forage production and protein as well as high soil CEC content at the riverbed.

Research and development(R&D) activities consist of analytical survey and state-of-the-art report writing for technical information. As R & D activities become more concrete, it often happens that they refer to related technical documents that were created in previous steps or created in previous similar projects. This paper proposes a research-task based reuse recommendation framework(RTRF), which is a reuse recommendation system that enables researchers to efficiently reuse the existing artifacts. In addition to the existing keyword-based retrieval and reuse, the proposed framework also provides reusable information that researchers may need by recommending reusable artifacts based on task similarity; other developers who have a similar task to the researcher's work can recommend reusable documents. A case study was performed to show the researchers' efficiency in the process of writing the technology trend report by reusing existing documents. When reuse is performed using RTRF, it can be seen that documents of different stages or other research fields are reused more frequently than when RTRF is not used. The RTRF may contribute to the efficient reuse of the desired artifacts among huge amount of R&D documents stored in the repository.

As for the "Guang-Xi(廣西)", "Dong-Shan(東山)", "Yao-Ju(瑤族)", folklore culture to achieve the substratum (New Year manners and customs, a passage rites, folk belief, dwelling folklore, agriculture and a farming machine) generally very received an influence of "Han-zu(漢族)" for the reason that an interchange was active early with "Han-zu(漢族)". However, a traditional form of "Yao-Ju(瑤族)" is covered the base with. Even if it is a national holiday commemorateing the birth of the "Pan-Gu(盤古)" which is ancestors of all "Yao-zu(瑤族)" during New Year manners and customs, songs as "ku-jia(哭嫁)" consisting at the time of marriage during a lot of ritual, "zhaoxu-hun (招婿婚)" and the "liangtou-che(兩頭扯)" marriages which are a classic marriage of "Yao-zu(瑤族)", a ritual format, master "Shi-Gong(師公)" of faith of "Yao-zu(瑤族)" are. Also, a difference is in dwelling folklore related to construction or this very much in "Han-zu(漢族)" and the various sides. It is the part where toilets to use are quite different from the Korean race in a tool, the outside written with the dwelling formal characteristics that are structure, "the ceremony of putting up the ridge beam" in, for example, two folds. Agriculture and a farming machine are basically similar to it of the Korean race, but it is a degree with some transformation by environment and the local cause.

It is well known that an Oscillating Water Column Wave Energy Converter (OWC-WEC) is one of the most efficient wave absorber equipment. This device transforms the vertical motion of water column in the air chamber into the air flow velocity and produces electricity from the driving force of turbine as represented by the Wells turbine. Therefore, in order to obtain high electric energy, it is necessary to amplify the water surface vibration by inducing resonance of the piston mode in the water surface fluctuation in the air chamber. In this study, a new type of OWC-WEC with a seawater channel is used, and the wave deformation by the structure, water surface fluctuation in the air chamber, air outflow velocity from the nozzle and seawater flow velocity in the seawater channel are evaluated by numerical analysis in detail. The numerical analysis model uses open CFD code OLAFLOW model based on multi-phase analysis technique of Navier-Stokes solver. To validate model, numerical results and existing experimental results are compared and discussed. It is revealed within the scope of this study that the air flow velocity at nozzle increases as the Ursell number becomes larger, and the air velocity that flows out from the inside of the air chamber is larger than the velocity of incoming air into the air chamber.

The behavior of wave-induced pore water pressure inside the rubble mound and seabed, and the resultant structure failure are investigated, which are used in design of the composite breakwater representing the coastal and harbor structures. Numerical simulation techniques have been widely used to assess these behaviors through linear and nonlinear methods in many researches. While the combination of strongly nonlinear analytical method and turbulence model have not been applied yet, which can simulate these characteristics more accurately. In this study, olaFlow model considering the wave-breaking and turbulent phenomena is applied through VOF and LES methods, which gives more exact solution by using the multiphase flow analytical method. The verification of olaFlow model is demonstrated by comparing the experimental and numerical results for the interactions of regular waves-seabed and regular waves-composite breakwater-seabed. The characteristics of the spatial distributions of horizontal wave pressure, excess-pore-water pressure, mean flow velocity and mean vorticity on the upright caisson, and inside the rubble mound and seabed are discussed, as well as the relation between the mean distribution of vorticity size and mean turbulent kinetic energy. And the stability of composite breakwater are also discussed.

This study was conducted for a review of Park Se-chae's Theory of Rituals and eclectic features. He was in agreement with Song Si-yeol's allegation and Seoin's theory of rituals(西人禮論) in the 1659 controversy over propriety(己亥禮訟) and the 1674 controversy over propriety(甲寅禮訟). After that, he was cautious and criticized for Song's claims in 1683 discussion of Hyojong's sacrifices and Taejo's posthumous name. This tendency can be seen in his paper of rituals. He wrote "服制私議"(Private opinion of mourning clothes) etc. in his early life and wrote "關西昏喪契約束"(Covenant on wedding ceremonies and mourning ceremonies in the Gwanse province), "喪祭値疫痘說"(Mourning ceremonies and sacrifice when there is an epidemic) etc. in his later life. By comparing the books, we can identify changes in Park Se-chae's eclectic features. Early in life, he reviewed Gorye(古禮, Rituals of the old such as Liji) and the timely institutions(時制) on the "朱子家禮"(A book written by Zhuzi about family rituals). However, later in life, he reviewed Gorye and the Zhuzi Jiali on the timely institutions. The following is a summary of the above. His theory of rituals can be said that the eclectic features have changed from 'on Zhuzi Jiali' to 'on the timely institution'.

This paper examines the aspect of the novel which appeared in the union of the male and female relationship of "OkSuki", one of the novels of the 19th century. "Oksuki" is a work focusing on the relationship between men and women. It takes a narrative structure based on the relationship. It shows various aspects of the relationship through the structure in which the pluralities of plural persons are repeated. Other events and illustrations, except for the talk, are both an occasion of the alliance and an auxiliary role. At the beginning of the work, the main character's parents are described in detail.By arranging the prophecies related to the relationship between the protagonist and the brothers, it suggests that subsequent narratives will flow into the center of the relationship. The male characters that make up the alliance are characteristically trained and have a good taste, and the Caines are colorfully colored. It is believed that the marriage pattern faithfully follows the medieval status order. The reason why the figure of the person who becomes his wife and the person of the concubine are set differently is because the image of the wife and the concubine are different from each other ideally. The characters who are going to be hungry are emphasized on the clause, efficacy, knowledge, and inner peace, and are actively involved in. On the other hand, conciliatory characters emphasize talent and craftsmanship, and their role is reduced after marriage. The wife is a person who has both Confucian culture and knowledge and is able to care for her husband and family well. Concultation is shaped as a person who can enjoy joyful life and emphasize more affection in relation with his wife.

The curiosity of the human afterlife created many imaginations. The Death Angel's Character are also the product of this imagination. This is because we needed a connection between this world and the otherworld in human' imaginations. The Death Angel revealed in detail in Shamanistic Epics. First, It is the person who performs the task assigned by The King of the Otherworld. Second, It is a person who can go to this world and the otherworld. Third, It is the person who takes the deceased to the otherworld. Fourth, It is the person who takes out the soul of human and modify the life list. Fifth, It is the person who sympathetic and humane qualities. This The Death Angel's character is actively accepted in modern contents. The most representative works are <49 Days>, , . Contemporary content, but the otherworld and the afterlife were accepted. And The Death Angel played an important role. Of course, this process also happens that modern changes. Namely, Function and personality retains existing character. And the appearance and background change a modern sense. As a result, The Death Angel became a new character through the encounter between the past and the present.

This paper seeks to provide an overview on the newly-discovered manuscript in gasa style. It is significant in that the entire in gasa style has not been seen before, although occasionally scripts incorporate sijo or gasa as inserted songs. The author of this manuscript is believed to be Bae Hyung (裵珩: ?-?), who lived in Daegachon, Yongdu-Myun, Sunchon-Gun in Jeonra-Namdo Province. It is estimated that the manuscript was written in April of King Gojong 37 years (year 1900). This , so-called the Yang Jee-Uk Collection Script, applies Samdan Pyunun Daewoo Method (三段片言對偶法), using Jongbae style (縱排法) to over 27 pagesof the book. The author seems to have collected the main scenes of and changed them into gasa style. It is also possible to postulate that the author might have simply divided the lines to make it resemble the existing gasa style, as the original was already in the form of lyrics. There are a few mistakes found in the manuscript. They seem to have been made while the author was recording the sung P'ansori, rather than while copying from a different manuscript.

1950-meter-tall goddess is Seolmundae Grandmother with the head of the 1950m Hallasan Mountain Baengnokdam and the body of the mountain ridgeline. Seolmundae Grandmother in Jeju is a folk belief that has been passed down from generation to generation in Jeju. Unlike inland, Seolmundae Grandmother, which had femininity in the customs of Jeju, which was a matrilineal society, developed into an absolute faith in Jeju, metaphorizing that in some way it was inevitable. Seolmundae Grandmother was the only subject that could mentally solve the biggest problem for Jeju residents, even if they were disconnected from the mainland. In other words, Seolmundae Grandmother was unable to make underwear for Seolmundae Grandmother because it was short of 100 bottles of silk, the god of Hallasan, a huge being and a physical symbol. Therefore, Semyungju Grandmother gave up the bridge connecting the mainland and Jeju. In this paper, focusing on the fact that Mt. Halla, covered with snow in winter, is like a skein of silk thread that we usually use in our daily lives, the etymology of Seolmundae has been changed to Saengmyeongju, - Semyungju, which is a skein of fine silk. As a basis for this, there is a custom of tying a thread of silk in 'Semyungju', a shrine to Semyeongju in Halmangdang, 'Hanmosal' along the coast of Pyoseon-myeon. The silk thread is the core of the Packing DNA gene. The summit of Mt. Halla, Ninety-Nine Valleys, and five hundred generals, found in Seolmundae Grandmother or White Silk, expressed the symbols of Jeju. The Packing DNA gene was found to originate in the Jeongnang
