Based on a follow-up study on critical fashion's strategies for object appropriation, this study aims to understand the appropriation of art as a social or cultural phenomenon influencing modern fashion, as well as to analyze and comprehend how to specifically approach the appropriation of critical fashion's letters through the appropriated interpretation. To explain the theoretical background of critical fashion's appropriated interpretation, it examined the related literature and data. Moreover, a fashion book-based literature review and a case study were conducted using sources, such as exhibition books, exhibited works, news, fashion magazines, and fashion sites, to examine letter appropriation strategies. In the critical fashion, the appropriation of subversive letters subverts meanings by providing experiences different from those based on real images of letters, which are displaceable. The appropriation of such subversive letters to challenge the value of modernism aims to subvert social value by bringing and relocating existing objects while focusing on their external forms. The appropriation of referential letters focuses on delineating the distance between the subjects who quote something and the quoted something and reprograms the existing letter objects with an introspective and reflective attitude. In other words, critical fashion designers can effectively express their messages through the appropriation of letters, such as graffiti and typography, which are manifestations of challenge or resistance. Appropriating letters as a creative action pursues unmarginalized humans who possess their existence.

In this paper, we consider changes of algebra strands around the world. And we suggest needs of designing new computer environment where we make and manipulate geometric recursive patterns. For this purpose, we first consider relations among symbols, meanings and patterns. And we also consider Logo environment and characterize algebraic features. Then we introduce L-system which is considered as action letters and subgroup of turtle group. There are needs to be improved since there exists some ambiguity between sign and action. Based on needs of improving the previous L-system, we suggest new commands in JavaMAL microworld. So we design a microworld for recursive patterns and consider meanings of letters in new environments. Finally, we consider the method to integrate L-system and other existing microworlds, such as Logo and DGS. Specially, combining Logo and DGS, we consider the movement of such tiles and folding nets by L-system commands. And we discuss possible benefits in this environment.

The biochemical characteristics of Astradix -P, isolated from Astragalus membranaceus Bunge as yeaststatic substance, were reported on a previous paper. And on this report, some relation to the nitrogen metabolism of yeast was studied. Inorganic or organic source of nitrogen easily uptaking yeast did not show any antagonistic action to the inhibitory action of Astradix -P on the yeast growth. Especially an organic nitrogen source, arginine, histidine and lysine, classified to basic amino acid, was reacted as an antagonistic substance to the sample. But, ornithine, a basic amino acid, did not show any antagonistic action to the sample. In the mixed media containing neutral and acidic amino acids as a nitrogen source, yeast growth was inhibited strongly. If the basic amino acid was added to the same mixed media, the yeast growth was not inhibited by Astradix-P therefore, the antagonistic action of basic amino acid to the Astradix-p was readily observed. The yeast static action of Astradix-P was partially related to the isoelectric point of amino acid as a nitrogen source. Yeast cells which propagated under the media containing growth inhibitor, Astradix -p, did not bring any remarkable denaturation of cell structure by electro-microscopic observation.

이 논문은 사람의 비언어적 행동을 자동적으로 분석하는 것을 목적으로 60 가지의 기본적인 사람의 윗몸 동작들을 인식하는 방법을 제안한다. 사람 몸동작을 인식하기 위한 방법으로 확률적 문법 추론법을 이용하였으며 모든 관절의 움직임 분석으로 임의의 동작을 인식하는 방법을 사용하였다. 시스템의 입력 데이타로 쓰여지는 각 관절의 실세계 3 차원 좌표들을 일정간격으로 양자화한 후, 각각 xy, zy, 평면에 투영하고, 이들을 다시 4방향 코딩하여 확률적 문법 추론법에 적합한 입력형식으로 변환한다. 또한 비언어적 행동 분석을 위한 사람의 동작 인식에는 손과 다른 부위와의 관계인 근접 정보가 동작 구분의 중요한 요소가 됨을 감안하여, 확률 문법 추론 방법을 확장하고, 일반적인 확률 문법 추론 방법과 비교하여 인식률이 향상됨을 실험결과를 통해 확인하였다.

This study was conducted to investigate the effect of an anti-inflammatory and analgesic action of the glucosamine HCl (Glucosamine) and SH-1 (Glucosamine + Oriental herbal composition combined group). Male sprague-Dawley rats $(200{\sim}250g)$ and ICR mice $(20{\sim}30g)$ were randomized and these experimental groups were divided into 4 groups. Two control group were given as negative control (saline) and positive control (Ibuprofen, 100 mg/kg) and two groups given as oral administration of Glucosamine (320 m/kg) and SH-1. Carrageenan induced paw edema test, hot plate method, croton oil induced granuloma, capillary permeability test and acetic acid writhing syndrome were also shown to be comparable in the SH-1 group to anti-inflammatory drug group such as positive control group (Ibuprofen). Although further studies should be performed to confirm the effects of SH-1, present results suggest that the combined administration of SH-1 have potential action in anti-inflammatory and analgesic action. It could be applicable for the improvement of arthritic symptoms as a new diet-supplement.

Proteolytic enzymes secreted by Aspergillus, as pathogenicity factors, affect blood coagulation and fibrinolysis, and therefore the target proteins of their action in the bloodstream are of significant interest. In the present study, the action of the isolated protease of A. terreus 2 on different human plasma proteins was shown. The protease of A. terreus 2 exhibited the highest proteolytic activity against hemoglobin, which was 2.5 times higher than the albuminolytic activity shown in both of the protein substrates used. In addition, the protease has significant ability to hydrolyze both fibrin and fibrinogen. However, the inability of the A. terreus 2 protease to coagulate rabbit blood plasma and coagulate human and bovine fibrinogen indicates the severity of the enzyme's action on human blood coagulation factors. It should be considered as a potential indicator of this isolated protease's participation in fungal pathogenesis. The protease shows no hemolytic activity. Furthermore, its activity is insignificantly inhibited by thrombin inhibitors, and is not inhibited by plasmin inhibitors.

An extracellular enzyme showing lytic activity on E. coli peptidoglycan had been isolated from Bacillus sp. BL-29. The lytic enzyme was purified to homogeneity by ion-exchange chromatography and gel filtration, with a recovery of 5%. The enzyme was monomeric and had an estimated molecular weight of 31,000 Da. The mode of action of the purified enzyme was also investigated. When the purified lytic enzyme was incubated with cell wall peptidoglycan, N-terminal amino groups were released without the release of reducing groups. The N-terminal amino acid released was identified as dinitrophenylalanine (DNP-alanine) by analysis of terminal amino acid by dinitrophenylation method. This result suggests that the lytic enzyme should be a kind of N-acetylmura-myl-L-alanine amidase.

A bacteriocin was isolated from the supernatant fluid of M17G broth culture of Lactococcus sp. HY 449 strain, which showed strong inhibitory activity against the growth of selective indicator strain, Lactobacillus fermentum IFO3023. When the bacteriocin wasa added to the growing indicator cells or cell suspensions, viable cells and optical density were density were decreased, indicating bacteriolytic mode of action. Electron microscopic observation of indicator cells treated with bacteriocin revealed apparent damages on the cell surface and eventual lysis of cell walls.

Enhancers are cis-elements to regulate transcription of cell/tissue-specific genes in multicellular organisms. These elements locate in upstream or downstream regions of target genes and are found in a long distance up to 100 Kb in some cases. Transcription factors and coactivators bind to enhancers in a chromatin environment. Enhancers appear to facilitate the transcription of target genes by communicating with promoters and activating them. As transcription activation mechanism of enhancers, chromatin looping between enhancers and promoters, tracking of enhancer activity to promoters along the intervening regions, and movement of enhancers and promoters into transcription condensates have been suggested based on various molecular and cellular biology studies. These mechanisms are likely to act together rather than exclusive each other for gene transcription. Understanding of enhancer action mechanism may provide a way to regulate the transcription of cell/tissue-specific genes relating with aging or various diseases.
