  • Adaptive laboratory evolution (ALE) is an evolutionary engineering approach in artificial conditions that improves organisms through the imitation of natural evolution. Due to the development of multi-level omics technologies in recent decades, ALE can be performed for various purposes at the laboratory level. This review delineates the basics of the experimental design of ALE based on several ALE studies of industrial microbial strains and updates current strategies combined with progressed metabolic engineering, in silico modeling and automation to maximize the evolution efficiency. Moreover, the review sheds light on the applicability of ALE as a strain development approach that complies with non-recombinant preferences in various food industries. Overall, recent progress in the utilization of ALE for strain development leading to successful industrialization is discussed.

  • With the continued evolution of third-generation cellular systems and the introduction of 3GP P LTE, there is considerable progress for the new mobile wireless markets. Recently, 3GPP LTE standards are accelerated by mobile operators supporting LTE deployment and special working groups such as LSTI are working for LTE IOT and trials. In this paper, we introduce the current status of LTE activities in the mobile communications industry.

  • 금강에서 채집된 Acheilognathus sp.의 분류학적 위치를 밝히기 위하여 이들의 형태적 및 유전학적 특성을 검토하고 속 내의 유사종인 줄납자루 및 큰줄납자루와 비교하였다. 이들은 많은 형태적인 특징에서 거의 비슷하였으나 수컷의 혼인색인 등지느러미와 뒷지느러미 가장자리에 붉은 띠가 있고, 배지느러미 가장자리에 흰 띠가 있으며, 최대 체장이 줄납자루보다 큰 점, 계수형질에서는 척추골수가 다소 많은 점과 새파수는 적은 점 등의 특징에서 A. sp.가 다른 두 종과 차이가 있었다. 계통 분석에 의하면 A. sp.는 큰줄납자루 및 A. cyanostigma와 단계통을 형성하였으며 줄납자루와는 Acheilognathus속 내의 다른 종들보다도 더 먼 관계를 가지고 있었다. 따라서 금강의 A. sp.는 줄납자루, 큰줄납자루 및 일본의 A. cyanostigma와 형태, 분포 및 유전적 특성에 의하여 구별되는 다른 종의 수준에 있다고 생각된다.

  • Pyrgotidae is a small acalyptrate family including about 370 species worldwide and little attention has been given to their systematics until recently. Latest changes in taxonomic status of some of the Korean species made this review inevitable. In the present study, the Korean pyrgotid species are reviewed with discussion of their taxonomic status. We also provide a revised key to all 14 Korean species (seven Adapsilia, three Eupyrgota, two Parageloemyia, one Porpomastix, and one Tephritopyrgota species) supplemented by digital images to facilitate accurate identification.

  • The purpose of this study is to understand the meaning of architectural history of designated cultural properties of modern educational facilities through the analysis of its status. This study considerate acceptance and evolution of modern educational facilities during the about seventy years from 1895 to 1965. Also, this study analyzes items that is distribution of construction and designation year, regional groups, and status of main structure material, status of conservation and utilization of facilities, its characteristics of architectural style. In this study, the result of analysis show that most analysis items of investment buildings are tend to biased and concentration to one direction. Accordingly, designated cultural properties of modern educational facilities are weakly express architectural representation and symbolism in the period of modern educational acceptance.
