ERROR ESTIMATES FOR THE FULLY DISCRETE STABILIZED GAUGE-UZAWA METHOD -PART I: THE NAVIER-STOKES EQUATIONS

Pyo, Jae-Hong The Kangwon-Kyungki Mathematical Society 2013 한국수학논문집 Vol.21 No.2

The stabilized Gauge-Uzawa method (SGUM), which is a second order projection type algorithm to solve the time-dependent Navier-Stokes equations, has been newly constructed in 2013 Pyo's paper. The accuracy of SGUM has been proved only for time discrete scheme in the same paper, but it is crucial to study for fully discrete scheme, because the numerical errors depend on discretizations for both space and time, and because discrete spaces between velocity and pressure can not be chosen arbitrary. In this paper, we find out properties of the fully discrete SGUM and estimate its errors and stability to solve the evolution Navier-Stokes equations. The main difficulty in this estimation arises from losing some cancellation laws due to failing divergence free condition of the discrete velocity function. This result will be extended to Boussinesq equations in the continuous research (part II) and is essential in the study of part II.

Secondly, the self-directed learning was enhanced by the appearance of the graphic form so that the result of the work such as the analysis of the transaction and the calculation of the account of the balance sheet can be visually confirmed. Third, the analysis of the transaction includes the profit and loss settlement transaction, so that the whole cycle of accounting can be examined. Fourth, we have made it possible to view both the main books of accounting and the general ledger, and to prepare the total balance of the financial statements. The learner-centered analysis of the explanation form through EXCEL program file can contribute to the achievement of effectiveness and efficiency, and the excellence of education.

리황의 철학사상에 대하여

변정암 慶北大學校 退溪硏究所 2004 退溪學과 韓國文化 Vol.- No.35-2

퇴계 이황은 16세기의 대표적인 관념론철학자이다. 이황의 철학사상은 총체적으로 존재론과 의식론, 윤리설로 이루어져 있다. 우선 그의 존재론에서는 이를 운동능력을 가지고 스스로 운동하며 우주만물을 낳는 '능발능생'의 존재로 규정하면서, 그 위치를 상제의 높이에까지 끌어올려 '극존무대'의 절대적 존재로 정립하였다. 또한 이것에 기초하여 이일원론적 경향을 뚜렷이 하였는데, 이것은 그의 인식론에서도 명백히 나타나고 있다. 그는 인식주체와 인식대상의 원칙적이며 본질적인 구분을 부정하였는데, 이것은 인간의 인식과정은 본질에 있어서 자기의 본성 속에 이미 선천적으로 갖추어져 있는 이를 사물현상을 통하여 확인해보는 과정에 불과하다는 것이다. 더 나아가 사물현상에 대한 인식과정이 이 스스로의 자기 발현에 의한 자기 인식과정임을 명시하는 '이자도'설을 주장하였다. 이황은 윤리설 또한 이일원론에 기초하여 전개하였는데, 대표적인 것은 '주경(主敬)'론이다. '경'에는 두 개의 단계가 있는데, 첫 단계는 개개의 사물을 각각 전일하는 단계이고, 두 번째 단계는 하나에서 완전한 조화를 이루는 단계 즉. '물아통일'의 경지이다. 이처럼 '물아통일'을 '경'의 최고 이상경계로 세운 것은 '천리'에 부합되는 인간의 도덕적 완성의 필연성을 확증하자는데 있었다. Yi Hwang in the pen name Toe'gye, is the representative philosopher of idealism in the 16th century. His philosophy mainly consists of ontology, study of consciousness, and ethics. Considering reason (li) and energy (ki) as a unified unit, Yi Hwang denies the distinction between the subject of thinking and the object. According to his theory, a man cognizes phenomenon, availing his inborn ability to reason, which is called as the theory of Lijado.

The purpose of this study is to find to relationship among the children's peer status, friendship quality, and conflict resolution strategie in children's friendship. The object of this study were 417 children in 5th grade of elementary school in Seoul. The measuring instruments used for study were peer nomination developed by Coie and Dodge(1983), Friendship Quality Scale developed by Lee and Koh(1999) and a Scale on Friendship Conflict Resolution Strategies (Rhee, Koh & Oh, 2000). The Collected data was analyzed by SPSSWIN statistical program. The frequency and percentage were calculated to investigate the general characteristics of the subjects. One-Way analysis was performed to find relationship among the children's peer status, friendship quality Mutiple Regression was performend to find relationship among the children's peer status, friendship quality, and conflict resolution strategie in children's friendship. The major results of this study are as follows, First, concerning about peer status and friendship quality, pouplar group have a positive friendship but, rejected group have a conflictive friendship. Second, while popular group used various strategy in conflict resolution, neglected group used evasive strategy. Third, concerning about relation between quality of friendship and frienship conflict resolution strategy, while the group which has high degree of emotional stability, intimacy and human desire used negotiation, cooperation and concession strategy, the group with has low degree of cooperation and pleasure of friendship used evasion and away strategy. Fourth, concerning the effect of friendship quality according to peer status which influence conflict resolution strategy between friendship, each popular, average, rejected and neglected group gas different quality of friendship and according the lower factor of friendship quality, each group has different conflict resolution strategy. Therefore I suggest that according to the peer status, arbitration program should be selected with propriety.

The purpose of this research was to reveal differences in advertisement effects between official sponsors and ambushing marketing companies, in the aspects of the attitudes in advertisements about company, product goodwill degree, purchasing intentions, company images, and changed consumer attitudes after ambush marketing were verified, establishing concepts through theoretical surveying previous researches about ambush marketing and through practical and experimental analysis. The results of those practical analysis were outlined below: Domestic consumers generally had positive recognitions about official sponsors and trusted them, but they could not easily differentiate ambush marketing from official advertisements due to barely understanding what official sponsors are. That reason was that they were difficult to recognize official sponsors in advertisements. Furthermore, respondents to the questionnaire did not change their positive attitudes towards advertisements after recognizing the fact that official sponsors they had thought were in fact ambush marketing. Therefore there were no or little differences between ambush marketing and official sponsors in the aspects of the attitudes in advertisements about company, product attitudes, purchasing intentions, and company images.

이표상 한국스포츠리서치 2004 한국 스포츠 리서치 Vol.15 No.1

The purpose of this study was to examine if previous studies on socio- active adaptation of androgynous identity types is useful in an andocentric ROTC group environment specifically from the perspective of gender integration. For this purpose, participants were classified in four categories according to type of gender role identity of men and women, perception level of Physical Self-Efficacy Scales (PSES) by type and the differences in Physical Training Test Scores (PTTS) were analyzed. Participants in the current study include 172 volunteer undergraduate students (84 males and 86 females) participating as cadets in the Texas A&M University Corps of Cadets. The study found males PSES perceptions, masculinity and androgyny identity had higher perception levels than other types. Therefore, the first hypothesis, that the perception level on the PSES of the androgynous type is higher or the same that of the masculine type was supported for the male students. In the case of female students, it was shown that the perception level of the androgyny type was higher than that of other types. Therefore, the first hypothesis was also supported for female students. The difference of the males PTTS by the type of gender role identity was analyzed. The study found that masculine identity type scored higher than other types. Therefore, the second hypothesis, that the androgyny type will lead to better PTTS scores, was not supported for male students. In case of female students, differences were observed among the masculinity, femininity and unclassified types. The androgyny type was different from the femininity and unclassified type. However, the mean difference between the masculinity types was not observed. The second hypothesis was accepted for female students. An interesting similarity between the two types was considered to be the homogeneous group attributes between the two types. As a result, the researcher contends that both masculinity identity and androgyny identity will be useful psychological health index in an ROTC environment.

韓國 假面劇의 男役

성병희 安東大學 1984 安東大學 論文集 Vol.6 No.1

An appropriate understanding of Korean masqus within the domain of fol Klore requires dual aspects in their evaluation: in terms of a folk art, and as means to appreciate the consciousness of masses, historical background, and the social structure in relevant ages. This paper was intended to classify and characterize the male entry in Korean masques. The numbers of male participants are: 17 men in Yang-chu pyolsandae Nori, 22 in song-`pa sandae Nori, 24 in pong-san Mask Dance. 16 in Kang-nyong Mask Dance, 17 in T`ong-yong O-kwangdae, 15 in Ko-song O-kwangdae, 24 in Kasan O-kwangdae, 9 in Su-yong Yaryu, 17 in Tong-nae Yaryu, and 6 in Hahoe pyolshin Marsk play. The social strata of all the male characters can be divided into the ruling class, the ruled class, and a group of people who are in neither. Typologically they can be classified as: a Budhist monk, a yangban, a patriarch, a Malttugi (usually taking pleasure in revealing the absurdity of yangbans), a Ch`wjbari (usually teasing the sinful monks), a p`odo-Taechang or a policenchief (representing the middle class and criticizing yangbans), and a Tokki or an axe (notorious for disobedience to its parents).
