Foot rot symptoms were occasionally observed on young bok choy (Brassica rapa subsp. chinensis) and kale (B. oleracea var. viridis) plants grown in vinyl greenhouses located in Icheon and Yangpyeong, Gyeonggi Province, Korea. These observations were made during disease surveys in April 2020. The incidence of diseased plants in the vinyl greenhouses investigated was 0.5-1.0% in bok choy and 0.5-5.0% in kale. Five isolates of Rhizoctonia sp. were obtained from diseased roots of bok choy and three isolates of Rhizoctonia sp. were taken from diseased stems of kale. All the Rhizoctonia sp. isolates were identified as Rhizoctonia solani AG-2-1 based on the morphological characteristics and anastomosis test. Three isolates each of R. solani AG-2-1 from bok choy and kale were tested for pathogenicity in their host plants by artificial inoculation. The tested isolates induced foot rot symptoms on the inoculated bok choy and kale plants. The symptoms on the bok choy and kale, induced by the artificial inoculation, were similar to those observed on plants from the vinyl greenhouses that were investigated. This is the first report of R. solani AG-2-1 causing foot rot in bok choy and kale in Korea.

Objectives: Bok, Bcl-2-related ovarian killer, is a proapoptotic Bcl-2 family protein identified in the ovary based on its dimerization with the antiapoptotic protein Mcl-1. The present study examined the hormonal regulation and localization of Bok messenger RNA levels in the mouse ovary during the follicle development. Methods: The animals were implanted subcutaneously with Silastic brand capsules containing the synthetic estrogen, DES at $21{\sim}23$ days of age. Ovaries were collected $1{\sim}3$ days after implantation for RNA analysis and in situ hybridization. Some mice were removed capsule for $1{\sim}2$ days to induce ovarian follicle apoptosis. Ovaries were also collected from 26 day-old immature mice at various times after treatment with 10 IU PMSG. Some mice received a single intraperitoneal injection of 10 IU hCG to induce ovulation, and ovaries were obtained at different time intervals for Northern blot and in situ hybridization analysis, respectively. Results: Treatment of immature mice with diethylstilbestrol (DES) for $24{\sim}48$ h increased ovarian Bok mRNA levels. Bok mRNA was remained the same levels in mice removed DES for $24{\sim}48$ h to induce apoptosis. High signals of Bok mRNA after DES treatment were detected in granulosa cells of early antral follicles. Treatment of immature mice with PMSG for 12 h increased markedly ovarian Bok mRNA expression which was detected mainly in preantral and atretic follicles. Interestingly, low levels of Bok mRNA were also expressed in granulosa cells of preovulatory follicles. Treatment of PMSGprimed mice with hCG stimulated strongly ovarian Bok mRNA expression at $6{\sim}9$ h. At that time, Bok mRNA was expressed in granulosa cells of atretic and small growing follicles. Conclusion: These results demonstrate that Bok is one of proapoptotic Bcl-2 members expressed in early growing and atretic follicles during the ovarian follicular development. Gonadotropins induce a transient increase of Bok gene expression in granulosa cells of preantral and preovulatory follicles indicating some role in the ovulatory process.

During the period of 3rd Tae-Jong and 4th Se-Jong, Yi Dynasty has established sound basis for ruling power and aristocratic social cast system. And the regulation for official dress has also been firmly established during the same period. The establishment of KWAN BOK SACK (Office of Hat-Dress) in 16th year of Tae-Jong (1416 A.D.) and the enforcement of KWAN BOK JI JAE (System of Hat and Dress) in 8th year of Se-Jong(1426 A.D) indicates the completion of system of official dress in the dynasty. In this study, the author tried to find out the concept of color in the ruling society since the concept of color in KWAN BOK JI JAE, which is the social reglation in the fendal dynasty, had greatly been influenced by these class of people. Effort has also been given to investigate what motivated the establishment and enforcement of KWAN BOK JI JAE, through the descriptions revealed in SE-JONG SILLOK. It can be concluded in the first that, in KWAN BOK JI JAE no new color concept appeared and its significance only remains on the fact that it establshed the social regulations which were existed before. And secondly, the works of Se-Jong in KWAN BOK JI JAE, in contrast to his magnificance in other fields, only showed great influence of toadyism (Chinese culture).

Background : Tremor is a rhythmic, involuntary muscular contraction characterized by oscillations (to-and-fro movements) of a part of the body. Tremor is the common symptom clinically. Objectives : The purpose of this study is to show a case of patient with tremor improved by medication of Bok-jin-centered. Patients & Methods : The patient was 60-year-old woman who complained Cephalic and cheilo tremor. She was treated by oriental medicine with acupuncture, herb medication, physical therapy through the abdominal diagnosis, Bok-Jin. Results : The Cephalic and cheilo tremor was reduced after oriental medical therapy. Conclusion : After the treatment, tremor and other symptoms were improved. This result suggested that Bok-jin is the significant diagnosis and medication of Bok-jin-centered is recommanded.

In light of Korean inclusion of its diaspora as part of the nation, a "creolized" approach that brings together constructions of the bad subject of Asian American studies with conceptions of the Korean minjung grounds an analysis of two poets as they might be considered from a bi-national, Korean and U.S. American, perspective. The poets Ed Bok Lee and Jason Koo show different ways of being the bad subject. Lee is clearly a bad American subject, resisting American white racial hegemony, and his poetry often addresses a kind of American minjung multiculturalism, as is shown in poems from his first two books Real Karaoke People and Whorled. He challenges some aspects of contemporary Korea, and might be a kind of Korean bad subject in those challenges. Koo, on the other hand, resists the call to bad subjectivity, so that his poetry may not fit the preferred paradigm of Asian American studies, as he recognizes. As he resists that paradigm, he also gives little attention to his Korean heritage, so his not-bad American subjectivity becomes bad Korea subjectivity. He recovers some measure of badness in the final poem of Man on Extremely Small Island when he connects briefly to his Korean heritage and his Asian American present. The creolized juxtaposition of the bad subject with the minjung suggests the use of these poems in considering both American and Korean society.
