Cellulase 분비 균주인 Trichoderma viride의 cellulase 생산능력이 높은 변이주를 선별, 분러하기 위하여 cellulose 기질이 첨가된 Plate상에서 작은 단일 colony를 형성시키고 분비된 cellulase가 배지내의 cellulase를 분해하여 생긴 clear zone을 육안으로 관찰함로써 cellulase생성 조절변이주 혹은 효소역가가 높은 균주를 식별할 수 있는 방법을 개발하였다.(중략)

Acne vulgaris is a chronic inflammatory skin disease related to pilosebaceous unit. In acne lesions, hyperseborrhea, dysseborrhea, inflammatory event, and an imbalance in skin microflora, particularly an increase in Cutibacterium acnes (C. acnes) colonization comparing to other bacteria, have been observed. The objective of this study was to evaluate anti-acne effects of Artemisia annua extract (AAE) on antibacterial activity related to preservation of the balance in skin microbiome, inhibition of inflammation, and reduction of excessive sebum production. When C. acnes and Staphylococcus epidermidis (S. epidermidis) were co-cultured in the presence of AAE, the reduction of C. acnes growth by AAE was greater than that of S. epidermidis. In addition, when C. acnes was cultured in a medium containing AAE (C. acnes AAE), levels of cytokines such as interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α) and IL-6 and toll-like receptors-2 activity were decreased in comparison with C. acnes cultured in a medium without AAE (C. acnes CM). Moreover, AAE significantly inhibited excessive sebum production induced by palmitic acid. These results suggest that AAE, as a natural extract with various targets, can inhibit selective growth of C. acnes and inflammatory reactions derived from C. acnes, which are the main causes of acne, and consequently can be used as a substance to alleviate acne by reducing excessive sebum formation.

In this study, the operational characteristics of a domestic vegetable transplanter were investigated. The main functional components and power path of the tranplanter were analyzed. The link structure of transplanting device waskinematically analyzed, and 3D modeling and dynamic simulation were performed. Based on this analysis, the trajectory of the bottom end of the transplanting hopper was analyzed. Also, the plant spacing according to the engine speed and the shifting stage of transplanting transmission was analyzed and verified by field test. As main results of this study, the transplanting device is one degree of freedom(DOF) 4-bar link type mechanism which comprises 10 links and 13 rotating joints. The transplanting hopper plants seedlings in a vertical direction while maintaining a constant posture by the links of transplanting device. The power is transmitted to both the driving part and transplanting part from the engine, and the maximum and minimum plant spacing of the transplanting device were 428.97 mm and 261.20 mm.

서점가에 사라진 책들이 부활하고 있다. 주로 70-80년대에 나왔던 책들 가운데 본의 아니게 퇴장한 책들이 산뜻한 표지 장정과 깔끔한 편집, 한글세대에 맞춘 문체와 호흡을 수혈받아 새 생명으로 되살아나고 있다. 신규 투자의 모험을 줄이면서 검증된 좋은 책을 되살린다는 점에서 출판계는 긍정적으로 평가한다.
