This research on the house folklore in China, Korea, and Japan is focusing on a kitchen God that is common in these three countries. This god originated in China and has subsequently influenced Korea and Japan. Today, all three countries use the same name of this kitchen god which is called Youngwang(竈王) as its name has been spelled in Chinese. In China, this kitchen god has been believed in two different ways. The Han people have developed their belief in Youngwang while another creed has been originated from other ethnic groups. Because of the particular house style with upper stories of ethnic groups in the southern and southeast areas of China, a kitchen fireplace is centered in the house. Han people in China also worship painted depictions of kitchen gods. And the ethnic groups believe it has three stone legs for a fire box. These differing beliefs has bad influenced on Korea and Japan. The kitchen god of Cheju island (off the south Korea coast) is believed to be almost the same as among the ethnic groups in China Interestingly, form of belief in the kitchen god in Okinawa (off the south coast of Japan) is almost identical as in the southern area of China Custom in China. Korea, and Japan regarding the kitchen god symbolized family values healing, initiating a new daughter-in-law to reveging the kitchen god, etc. are all the very similar. A fireplace and its fire are very important and, have many taboo, attached. Existing rich tales of kitchen gods are similar in the three countries. Moreover, people in the three countries, think that the clay or time plaster of the fireplace with bring good luck on New Year's eve. However, Korea kitchen god features one thing that is different from those China and Japan, that is that water symbolizes the kitchen god in Korea. A painted kitchen god as they are popular in China, has influenced only some Buddhist temples in Korea.

미국 국가안보국에서 개발된 경량 블록암호 SIMON은 하드웨어 구현에 최적화 된 블록암호 군으로서, 여러 환경에서 효율적으로 동작할 수 있도록 많은 입·출력 규격을 제공한다. 블록암호 카운터 운용모드는 블록암호의 입력 규격보다 더 큰 평문을 암호화할 수 있도록 제공되는 운용모드 중 하나이다. 카운터 운용모드는 입력 값으로 상수 값인 논스와 블록의 번호인 카운터를 사용한다. 이때 논스 부분은 모든 블록이 동일하기 때문에, 다른 상수 값과 연산한다면 항상 동일한 연산 결과를 가진다. 이 특징을 활용한다면 일부 값을 사전 연산하여 라운드 함수의 일부분을 생략하는 것이 가능하다. 일반적인 상황에서 SIMON의 입력 값은 카운터에 영향을 받으나, 8-bit 환경에서는 8-bit 단위로 연산이 되기에 고속 구현이 가능한 부분이 존재한다. 따라서 본 논문에서는 연산 생략이 가능한 지점을 중점적으로 확인하고 기존 SIMON 구현물과 성능 비교를 통해 제안하는 기법의 우수성을 확인한다.

Patricia Waugh once regarded modernism fiction as 'the struggle for personal autonomy' against the opposition existing social institutions and conventions. Michael Cunningham's characterizations of Virginia Woolf and Septimus in The Hours show the two contrasting reactions to individual alienation and mental dissolution in the modern era. As the personifications of endurance and self-destruction against the mechanical power of contemporary world, Woolf and Septimus consist of just the world of diptych where the woman's role is confined to the angel in the house. By creating Mrs. Brown based upon his own alienated mother image, however, Cunningham succeeds in representing the more dramatically vivid world of triptych where woman can have her own room and self-realization despite still facing the dilemma of the traditional family. Accepting Joycean Bloom's optimistic and relaxing way of life in part, Mrs. Brown connects the labyrinths between the author's (and also Richard's) alienation with the theme of celebration of the life. Clarissa in postmodern New York setting is still a concealed and mystified character. Similar to Mrs. Dalloway, on the one hand Clarissa watches other people's tragedy with compassion. Cunningham's Clarissa, on the other hand, is no longer seeking for either winning or defeat in the spectacular world unlike her predecessors. In many resilient attitudes of everyday life Clarissa is closest to Mrs. Brown whom Virginia Woolf originally hopes to describe. Without any fear or rage toward the society Clarissa witnesses and achieves "the humanity, humour, depth" of female values by successfully turning the trivial life into an epic journey.

This article proposes to stay away from contemporary critical arguments concerning Michael's value system, which is construed mainly from his choice between his patrimonial lands and his son Luke. Presuming that Michael's value system as have been argued so far could never be the poet Wordsworth's own concern at the time of the composition of the poem "Michael," this article proposes to get back to the all too real socio-historical situation of the early nineteenth-century England. Mere consideration of the socio-historical situation, when combined with a close reading of the poetic text (a close reading of both the poetic story and the poetic history from which the story may be said to have been constructed), directs us to the poet working on the simple paradigm of 'the country and the city at war with each other' but the victory having been given to the city already. The guarantee contract for a supposedly prospering nephew's debt and the letter from another prospering relative in London are undoubtedly the key elements that lead us to the war paradigm. Michael's family members, each and all including Michael himself, and all of their village people, have been imbued with the city's commercial values, which renders them all the more easier victims within the war context. Luke's defeat in the city is viewed as being really the consequence, rather than the cause, of Michael's defeat, which became apparent as soon as the news of the latter's financial disaster reached his ear. Michael should therefore be regarded as one of the typical English countryfolk of the time, with whom Wordsworth often, but not always, identifies himself. Insofar as the economic view or attitude is concerned, there certainly is a distance between Michael and Wordsworth, this article argues.

Bergenia ciliata (Family: Saxifragaceae) is a folklore remedy for the treatment of various ailments in Asian countries. Bergenin (1) has been isolated as an active constituent in many studies, however, the amount of bergenin has not been determined in all parts of the plant. A simple RP-HPLC method was developed to determine the amount of bergenin in methanol extracts of leaves, rhizomes and roots of the plant. Separation was achieved on an Agilent Eclipse XDB-C18 column maintained at 25 ℃ using isocratic solvent system (water: methanol: acetic acid; 62.5:37:0.5 v/v/v) adjusted at pH 2 0 at a flow rate of 1.0 mL/min. and detected at 275 nm. Correlation coefficient (0.9952) showed linearity of concentration (5-200 ㎍/mL) and response. The values of LOD (0.00947 ㎍/mL) and LOQ (0.02869 ㎍/mL) indicated that method was sensitive. The recovery of bergenin was 99.99-100% indicating accuracy of method. The methanol extract of rhizomes contained higher amount of bergenin (19.4%) than roots (9.2%) and leaves (6.9%). It is concluded that methanol extract of rhizomes is a better source of bergenin than other parts of the plant. The findings are useful for standardization of bergenin containing extracts and herbal preparations.

Cancer is an abnormal growth of cells in body which leads to death. These cells are born due to imbalance in cell proliferation mechanism. In 2018, WHO released new statistics on cancer incidence, mortality, and prevalence worldwide i.e., GLOBOCAN 2018 estimates for 28 types of cancer in which more prevalence of cervix and breast cancer. According to survey, in India about 7.8 million cancer deaths and 11.5 million new cases arise in 2018, which will increase to 19.3 million new cases per year by 2025. Though breast cancer as such is not explained anywhere in Ayurvedic compendia, correlations can be done with the Stana Arbuda. Ayurveda, the ancient system of medicine came into existence 1000's of years ago with an objective of maintaining the health of people and treating diseases. Many herbs used in Ayurveda have been screened for activity against cancer and in-vitro and in-vivo studies have given promising leads. The plant, called as "Mother of Medicine", Haritaki has been extensively studied for its various ailments because of its extraordinary healing potency. Haritaki (Terminalia chebula Retz.), Family: Combretaceae have a great therapeutic value and is widely distributed in India. Dried fruit of Terminalia chebula contains high quantities phenolic compounds consist of ellagic acid, gallic acid and chebulic acid. The fruit extract of T. chebula is having different biological properties like anticancer, antioxidant, hepatic and renal protective activities etc. In this study, we focus on the use of CO₂ extract of Terminalia chebula, on the breast cancer cell line MDA-MB-231. All tests proved that CO₂ extract of Terminalia chebula containing active chemical component, therefore our experiment showed the positive results for CO₂ extract of Terminalia chebula against breast cancer cell line cancer MDA-MB-231. The MTT assay results were used to evaluate the anti-cancer activity of the extract. The percentage of cell growth and cell viability were calculated from tabulated result values of MTT assay. Cell viability MTT assay also showed significant growth inhibition, at the same time statistical analysis of MTT assay also proved significant results.

Chitinase AO-801 is a hydrolase secreted by Arthrobotrys oligospora during nematode feeding, while its role remained elusive. This study analyzed the molecular characteristics of recombinant chitinase of Arthrobotrys oligospora (reAO-801). AO-801 belongs to the typical glycoside hydrolase 18 family with conserved chitinase sequence and tertiary structure of (α/β)₈ triose-phosphate isomerase (TIM) barrel. The molecular weight of reAO-801 was 42 kDa. reAO-801 effectively degraded colloidal and powdered chitin, egg lysate, and stage I larval lysate of Caenorhabditis elegans. The activity of reAO-801 reached its peak at 40℃ and pH values between 4-7. Enzyme activity was inhibited by Zn2⁺, Ca2⁺, and Fe3⁺, whereas Mg2⁺ and K⁺ potentiated its activity. In addition, urea, sodium dodecyl sulfate, and 2-mercaptoethanol significantly inhibited enzyme activity. reAO-801 showed complete nematicidal activity against C. elegans stage I larvae. reAO-801 broke down the C. elegans egg shells, causing them to die or die prematurely by hatching the eggs. It also invoked degradation of Haemonchus contortus eggs, resulting in apparent changes in the morphological structure. This study demonstrated the cytotoxic effect of reAO-801, which laid the foundation for further dissecting the mechanism of nematode infestation by A. oligospora.

Purpose : This study aims to examine the effect of ego resilience and social support on test anxiety for university students majoring in occupational therapy and use the results as foundational data for program development that can reduce test anxiety. Methods : The study's subjects were 173 university students who understood the study's purpose and consented to participate in the study from March 7 to 25 in 2022. These students were in their second, third, and fourth years, majoring in occupational therapy at a four-year B university in A Metropolitan City and a three-year E College in D-gun C Province. Among them, those with missing data or indicated extreme values were excluded, and data from the final 168 students were studied. Results : The averages of test anxiety, ego resilience, and social support of university students majoring in occupational therapy were 3.06, 3.41, and 3.81, respectively. The factor that affected test anxiety was investigated. It was the school year in which the test anxiety of fourth-year students was significantly higher than that of second-year students. In addition, a positive attitude, which was one of the sub-factors of ego resilience, and support from friends and family, which were the sub-factors of social support, had a negative impact on test anxiety. Conclusion : The results of this study are as follows: First, it is necessary to conduct a study to verify the level of test anxiety of university students majoring in occupational therapy and the factors influencing them. Second, the operation and consultation of non-curricular programs that improve the ego resilience of university students should be conducted in universities and departments. Third, a measure to recognize support from surrounding environment and to ask for help from people around them should be required for university students majoring in occupational therapy.

The physicochemical properties of traditional kochujang added with naked oat flours (0, 5, 10, 15%) were periodically examined during fermentation for 20 weeks at 25℃(± 2 ℃). The proximate composition of roasted naked oat flours were as follows: water 0.67%, ash 1.63%, fat 10.37%, protein 13.63%, carbohydrates 73.70%. The water contents of traditional kochujang added with naked oat flours decreased gradually according to the addition level. The pH of traditional kochujang added with naked oat flours increased according to the added level, whereas pH decreased gradually during fermentation. The acidity was opposite to pH. The L (lightness), a (redness) and b (yellowness)-values of samples increased according to the amount of added naked oat flours, whereas they decreased gradually during fermentation. The salinity and sweetness of samples decreased according to the amount of added naked oat flours. Amino acid composition of traditional kochujang added with naked oat flours was higher than that of the control during fermentation. Aspartic acid, alanine, leucine, and arginine were high in the case of traditional kochujang added with 0% naked oat flours, and aspartic acid, leucine, alanine, proline. And arginine were high in the case of traditional kochujang added with 15% naked oat flours. The dietary fiber content was 5.38g/100g in the case of 0% addition and 5.75g/100g in the case of 15% addition. As a result of the above results, it was found that the physicochemical properties of traditional kochujang added with naked oat flours could be improved, and the possibility of developing a traditional kochujang beneficial to health was confirmed.
