연구의 목적은 N1과 6번 자리에 다른 치환기를 가진 5-cyano가 치환된 pyrimidine 아날로그의 새로운 시리즈의 합성과 그것들의 항균성과 항진균성의 활성도에 대해 평가하기 위해서이다. 이 화합물은 MORE technique 를 이용한 potassium carbonate 의 존재하에서 ethylcyanoacetate, 치환된 thioureas, 적당한 알데히드의 제 3차 축합으로 합성 되어졌다. 항균성과 항진균성의 활성도는 25 mg의 농도에서 cup-plate 방법으로 측정되었다. 억제구역은 mm로 측정 되어졌다. 모든 화합물은 좋은 항균성과 항진균성을 보여주었다. P1과 P5는 S.aureus과 E.coli에 대해 최대 활성도를 보여주었고, P6은 모든 종류의 미생물에 대해 좋은 활성도를 보여주었다. P8 화합물은 C. albicans 에 대해 좋은 효과가 있음을 알아냈다. Norfloxacin와 griseofulvin는 합성된 화합물의 활성도와 비교되는 기준물질로 사용되었다. 6번 자리에 p-hydroxy와 p-methoxy로 치환된 phenyl moiety를 가진 gram-양성 미생물에 대해 강력했고, 6번 자리에 이것들이 없는 phenyl moiety 를 가진 아날로그는 gram-음성 활성도를 가졌다,6번 자리에 p-dimethylamino로 치환된 phenyl moiety를 가진 화합물은 적당한 활성을 보여준다.. 게다가 N1자리에서 단지 fluorine을 포함한 아날로그는 상당한 항진균성을 가졌음을 밝혀냈다. N1자리에서 aryl moiety 의 전자 끌게 치환과 마찬가지로 전자 주게 치환은 화합물의 결정된 능력에 중요한 역할을 함을 제시한다. purpose of the study was to synthesize new series of 5-cyano substituted pyrimidine analogues with different substitutions at N1 and 6 positions and to evaluate them for antibacterial and antifungal activities. The desired compounds were synthesized by tertiary condensation of ethylcyanoacetate, substituted thioureas and suitable aldehyde in presence of potassium carbonate using MORE technique. The antibacterial and antifungal activities were evaluated by cup plate method in the concentration of 25 mg. The zone of inhibition was measured in mm. All the compounds have shown significant antibacterial and antifungal activities. The maximum activity was shown by P1 and P5 against S.aureus and E.coli respectively, while P6 has shown significant activity against all types of microorganisms. The compound P8 has been found to be significantly effective against C. albicans. Norfloxacin and griseofulvin were used as standards to compare the activites of synthesized compounds. It is concluded that analogues containing p-hydroxy, p-methoxy substituted phenyl moiety at 6 position have been found to be more potent against gram-positive microorganisms, while analogues lacking these substituents on phenyl moiety possessed gram-negative activity. The compounds having p-dimethylamino substituent on phenyl moiety at 6 positions have shown moderate activity. Further, only fluorine containing analogue at N1 position was found to possess appreciable antifungal activity. This suggests that electron donating substituent on aryl moiety as well as electron withdrawing substituent at N1 plays important role in determining potency of the compounds.
Some Congruences for Andrews’ Partition Function EO(n)
Utpal Pore,Syeda Noor Fathima 경북대학교 자연과학대학 수학과 2021 Kyungpook mathematical journal Vol.61 No.1
Recently, Andrews introduced partition functions EO(n) and EO(n) where the function EO(n) denotes the number of partitions of n in which every even part is less than each odd part and the function EO(n) denotes the number of partitions enumerated by EO(n) in which only the largest even part appears an odd number of times. In this paper we obtain some congruences modulo 2, 4, 10 and 20 for the partition function EO(n). We give a simple proof of the first Ramanujan-type congruences EO (10n + 8) ≡ 0 (mod 5) given by Andrews.

For more than twenty years, Confucianism has experienced a renewal of interest. This best known of the ancient systems of thought originating in Sinic Asia, sometimes imprecisely regarded as a religion and in large part aphoristically philosophical, has nevertheless captured renewed scholarly and, to an extent, even popular interest. This is due not only to the interest of historians, but also to scholars in other fields, such as political science and international relations. All of these scholars have approached Confucianism in different ways resulting in sometimes contrasting valuations and interpretive debates. Yet, the viability of Confucianism per se, not its apparent manifestations in today’s world, in this writer’s view, is very suspect. How can it be considered extant when its ancient foundations, the institutions and people on which it depended for its interpretation, transmission, the performance of its functions and vitality have nearly completely vanished?

The Mobilization of Buddhism in Japan`s "Eight-Cornered World," 1941-1945
( William F. Pore ) 한국세계지역학회 2012 世界地域硏究論叢 Vol.30 No.2
From 1941 to 1945, during the Japanese wartime occupation of parts of China and Southeast Asia, the Japanese leadership attempted, through a plan based on the essentialization of Buddhism, to mobilize this religion`s adherents, so as to secure their unity and support in the ongoing war effort. This plan ostensibly sought to take advantage of one of the vagueries of "Asia." In Japan, the rudiments of the mobilization had been inspired by a re-imagining of an originally much older, semi-religious term, hakko ichiu (eight cords or corners of the world under one roof). The concept underlying this plan was therefore conveniently available and not entirely new. In 1941 the policy of mobilizing Buddhism was incorporated as a part of Japan`s cultural diplomacy and sought to create a "new order" in East Asia and "world peace." This study traces the early development of the mobilization plan in Japan, the contributions of a few of those who supported it, and then traces its implementation in Vietnam, one of the areas where it was conspicuously attempted. As it will be shown, not only in its conceptualization but also in its implementation, the mobilization of Buddhism proved ultimately to be opportunistic, and, by 1943, a desperate, unworkable measure.
