The movie offers a chance to observe the social signifier and the sensitivity of audiences who feel sympathy with the tragic history of crown prince Sado. While watching the movie, the audience halts between ideas whether to go back to "primary ego", or to play the unconscious hypocrisy or the ingrained social behavior which is to resolve the internal conflicts while they face two contrary opinions; one is the obedient subject to obey fatherness, as a symbol of historic value and convention in a society, and the other is the resistant body to break the bond of convention. The audience may feel some ambivalent feelings of the moral values between the paternal authority and the existential philosophical value of 'self'. This study will observe the audience's response of Sado toward the moral norms of the society when they face the signifier of father in the movie with experience the conflict between their resistant ego and madness. Also the study will discuss that the social landscape such as norms, order, and legal system is ever-changing and open to be subverted by the future even though audience hope that the present moral value with which we are content ever-last.

The treatment method of impacted tooth is various from simple observation to surgical exposure and orthodontic methods, autotransplantation is concerned to severe malposed impacted tooth. Autotransplantation is the transplantation of embedded, impacted, of unerupted tooth, into extraction socket of surgically prepared in the same individual. Autotransplantation of tooth with $\frac{1}{2}{\sim}\frac{3}{4}$ root development provides a good chance of easily extracted, a little complication, pulp survival, and complete root formation. Transplantation of uncompleted root apex tooth is aim to pulpal healing, not endodontic treatment. The case which were treated with autotransplantation is reported, and induced normal physiologic eruption and good dental alignment.

Revascularization of the pulp in a necrotic, infected immature tooth with apical periodontitis was attempting several years. Revascularization of partially necrotic pulp in an immature tooth is based on the concept that vital dental stem cells can survive pulpal necrosis. Revascularization procedure obtains longer and thicker roots in teeth with necrotic pulp diagnosis. Pulp revascularization for immature permanent molars can be possibly applied on cases having difficulty to use conventional root canal treatment due to abnormally thin root canal wall or severe root curvature. Also, when an uncooperative patient does not agree with sedative treatment the revascularization can be useful. And a patient with disability who is barely cooperative can be another indication of this treatment. In this case report, pulp revascularization using triple-antibiotics, metronidazole, ciprofloxacine and minocycline, was applied on the immature first permanent molar infected by caries.

Internet purchase is increasing according to the activation of Electronic Commerce. Currently, the hardware is main purchase items in the Electronic commerce. The on-line purchase of digital product, that is electronic file type of product, has many merits such as, does not cost in logistics, is ease of searching the product, and is possible of 'Try and Buy' system. But, actually digital products have not been major proudct because of tits piracy problem. The piracy problem of digital products comes from the lack of safety in DP license control technology. Current EC has no method to identify the object that has the right ot use the digital product. The protecting of object change is impossible and the protection of hacking is not enough and EC has any problems in efficient license control because of the incompletion of EC structure. In this paper, e propose the design and implementation of on-line DP circulation system, which can activate on-line circulation of DP in EC and protect its piracy, by using the new license control technology, that is Dynamic License control technology.

The study is to systematically review "DaedongYeojiJeondo", the mid-sized wood block map of Chosun to shed light on the cartographic characteristics not discovered by previous studies. First it was discovered that Kim Jung-ho is the developer of the map as the distance information from Seoul to towns is identical with the information on "Daedong Jiji" the manuscript map drawn by Kim Jung-ho himself (assumed to live from 1804~1866) that is still remaining unfinished. Second, the information Kim Jung-ho wanted to specify most precisely and specifically was distance from Seoul to towns and for this purpose he invented unique symbols for towns in tiny size on the map. Third, in selecting information to mark on the map including road network, street information, mountain routes and streams and location of islands, "DaedongYeojiJeondo" is not just a simple smaller copy of "DaedongYeojido" but an independent creative work as it is much different in many aspects of quality. Forth, but still "DaedongYeojiJeondo" and "DaedongYeojido" have something in common in the fact both of them tried to mark land and mountain routes and streams most precisely and specifically.

Branch prediction accuracy is critical for system performance in modern microprocessor architectures. The use of speculative update branch history provides substantial accuracy improvement in branch prediction. However, speculative update branch history is the information about uncommitted branch instruction and thus it may hurts program correctness, in case of miss-speculative execution. Therefore, speculative update branch history requires suitable recovery mechanisms to provide program correctness as well as performance improvement. In this paper, we propose recovery logics for speculative update branch history. The proposed solutions are recovery logics for both global history and local history. In simulation results, our solution provides performance improvement up to 5.64%. In addition, it guarantees the program correctness and almost 90% of additional hardware overhead is reduced, compared to previous works.

The STEAM education was applied to science high school students, and changes in perceptions of students and teachers were investigated after class treatment. By the results of the student's perception survey, very positive results were found in increasing problem-solving capabilities, educational satisfaction, etc. More than 98% of students said they would continue to participate in STEAM education classes. Meanwhile, the lack of time for class activities put a burden on students to complete the problems during class. Especially nanoscience content and activities were properly organized in consideration of the level of cognitive development of the students. In addition, as a result of a survey of teachers' perceptions for students, more than 80.0% of teachers responded very positively in 'self-directed learning ability' and 'problem-solving capability', etc.

The purpose of this study is to analyze the relationship between self-determination motivation of high school students on exercise satisfaction and exercise continuation intention. To this end, as of March 2022, an online questionnaire was distributed to 440 male students attending high schools in Seoul and Gyeonggi Province, and they were asked to fill out the questionnaire through self-assessment. 346 copies were selected as a valid sample, excluding 94 copies of insincere responses such as responses of the same pattern and incomplete responses. For data processing, frequency analysis, confirmatory factor analysis, and correlation analysis were conducted using SPSS 24.0 and IBM AMOS 18.0 statistical programs, and the following results were derived through structural equation model analysis to identify the structural relationship between factors. First, among self-determination motivation factors, competence and relatedness had a positive (+) effect on exercise satisfaction, but autonomy had a negative (-) effect on exercise satisfaction. Second, there was no relationship between self-determination motivation and exercise continuation intention in high school students. Third, it was found that the relationship between exercise satisfaction and exercise continuation intention had a positive (+) effect.

천연의 메탄 하이드레이트를 생산하기 위한 방법으로 몇 가지가 알려져 있으나 최근의 연구 결과로는 감압법이 가장 효과적이며 경제성을 확보할 수 있다고 알려져 있다. 하지만 이 방법을 이용한 메탄 하이드레이트 개발생산 시에는 해리된 물과 가스가 동시에 생산유체로 발생하여 수송되며, 생성수에는 하이드레이트 전구체라고 알려진 미완의 하이드레이트 구조체가 남게 된다. 생산유체는 낮은 해수온도에 노출되어 가스 하이드레이트가 쉽게 재생성될 가능성이 높기 때문에 안정적인 가스 생산과 생산시설의 보호를 위해서는 적절한 가스 하이드레이트 재성성 억제대책이 필요하다. Kinetic 억제제의 적용이 많이 이루어지고 있는 가스전에서의 경험을 바탕으로 투여해 보는 시도를 하고 있지만 sII인 천연가스 하이드레이트에서의 억제효과와 비교하여 저하된 결과가 보고되고 있다. sI과 sII는 메커니즘의 차이로 인해 억제제의 성능이 다르게 나타난다. sI인 메탄 하이드레이트에 대하여 kinetic 억제제의 효과를 살펴보았고 이온성액체를 적용한 효과적인 sI 하이드레이트 억제기법을 보고한다. 또한 기존의 sII 억제제와 혼합하여 시너지효과를 얻을 수 있음을 확인하였다.
