Some fatty acids(palmitic acid, stearic acid, oleic acid, linoleic acid and linolenic acid) in foxtail millet seeds were evaluated. In this study, 32 varieties of accession collected from different place of South Korea were used in order to evaluate their fatty acid composition and concentration. These samples were analyzed by GC with HP20 column. Significant variability in individual fatty acids was observed. The palmitic acid ranged from 10.9 to 13.5%, stearic acid from 2.5 to 8.3%, oleic acid from 10.0 to 15.8%, linoleic acid from 62.5 to 67.9% and linolenic acid ranged from 3.0 to 5.2%. This variability can be exploited for selection of plant and for studying the genetic variability in millet. These selections can also be utilized for genetic improvement of the crops.

This study aimed to provide basic data on current trends in floriculture through a survey. The exhibitors' purposes and items displayed at the Tokyo International Flowers & Plants Expo in 2017 were surveyed. The survey was conducted among 238 exhibitors during the exhibition period from October 11 to 13, 2017. As a result, participants came from 14 countries including Belgium, China, Colombia, Japan, Korea and France. The purposes of the majority of the surveyed exhibitors were to display cultivars (86 exhibitors, 36.3%), followed by to display merchandise, subsidiary materials and cultivation techniques. Among cultivars, pot plants accounted for the majority of the entire cultivars (54 exhibitors, 55.1%), followed by cut flowers (35 exhibitors, 35.7%), sapling, and seeds. The most of the displayed pot plants were ornamental plants (27 exhibitors, 43.5%), followed by garden trees, ground cover plants, bedding plants and succulent plants. The most of the displayed cut flowers were rose (8 exhibitors, 21.1%), followed by lisianthus, chrysanthemum and dahila. In terms of cultivation techniques, those using moss were displayed by 7 exhibitors (50%) and green-wall techniques were displayed by 6 exhibitors (42.9%). In terms of merchandise, processed products were displayed by 21 exhibitors (41.2%), followed by floral products. Therefore, the IFEX can be used as a place to understand current trends in the floriculture market.

Over the past decade or so, dramatic developments in our ability to experimentally determine the content and function of genomes have taken place. In particular, next-generation sequencing technologies are now inspiring a new understanding of bacterial transcriptomes on a global scale. In bacterial cells, whole-transcriptome studies have not received attention, owing to the general view that bacterial genomes are simple. However, several recent RNA sequencing results are revealing unexpected levels of complexity in bacterial transcriptomes, indicating that the transcribed regions of genomes are much larger and complex than previously anticipated. In particular, these data show a wide array of small RNAs, antisense RNAs, and alternative transcripts. Here, we review how current transcriptomics are now revolutionizing our understanding of the complexity and regulation of bacterial transcriptomes.

본 연구에서는 사용자의 감성 정보를 이용한 협업 필터링 기반 장소 추천 시스템을 개발하였다. 기존의 장소 추천 시스템은 장소에 대한 사용자들의 평점이나 방문패턴, 사용자들의 위치를 통해 장소를 추천하였다. 이러한 시스템들은 객관적이지 못 한 정보를 갖고 있거나 사용자의 상태를 고려하지 않아 만족도가 높지 않다. 사용자의 감성 정보를 이용하면 비슷한 감성을 느낀 사용자들이 방문하였던 선호도 높은 장소를 객관적으로 추천하여 장소에 대한 만족도를 높일 수 있다. 본 연구에서는 사용자가 직접 모바일 애플리케이션을 이용하여 현재 위치와 생체신호를 이용하여 인식한 감성 정보를 등록하고, 등록된 감성 정보를 이용하여 비슷한 감성을 가진 사용자들의 유사도를 측정하고 장소에 대한 선호도를 예측하여 사용자에게 감성 장소를 추천한다.

In this study, with the objects of 173 institutions of university and research institutions, investigation was carried out through visit investigation ar d questionnaire investigation. Frequency and severity of occurrences was acquired mainly through universities and research institutions which have reported occurrences of accidents to the Ministry of Education, Science, and Technology. Quantitative danger evaluation was conducted through frequency and strength of occurrences. Case study was carried out by selecting bio science laboratory of university and as the result of this study, degree of danger among the inspection objects of bio science laboratories, laboratory work place was evaluated as the most dangerous with the scores of 155.00 and as the result of average danger level, compression gas cylinder was evaluated as the most dangerous with the scores of 6.4000.

Ferroptosis is a new kind of programmed cell death of which occurrence in microorganisms is not clearly verified. The elevated level of reactive oxygen species (ROS) influences cellular metabolisms through highly reactive hydroxyl radical formation under the iron-dependent Fenton reaction. Iron contributes to ROS production and acts as a cofactor for lipoxygenase to catalyze poly unsaturated fatty acid (PUFA) oxidation, exerting oxidative damage in cells. While ferroptosis is known to take place only in mammalian cells, recent studies discovered the possible ferroptosis-like death in few specific microorganisms. Capacity of integrating PUFA into intracellular membrane phospholipid has been considered as a key factor in bacterial or fungal ferroptosis-like death. Vibrio species in bacteria and Saccharomyces cerevisiae in fungi exhibited certain characteristics. Therefore, this review focus on introducing the occurrence of ferroptosis-like death in microorganisms and investigating the mode of action underlying the cells based on contribution of lipid peroxidation and iron-dependent reaction.

The feeding habits of larval Engraulis japonicas (3.2-11.0 mm SL) were examined based on 414 individuals, collected in October 2010, and from June to September 2011, in the coastal waters of Eastern Jinhae Bay, Korea. E. japonicus, fed mainly on copepods 62.6% IRI and tintinnid were the second-largest dietary component. E. japonicus diet also included small quantities of rotifers, eggs and diatoms. The results of analysis of ontogenetic changes showed that E. japonicus of small size classes (${\leq}4mm$) fed primarily on tintinnids. The dietary percentage of copepods decreased, as fish size increased, and monogeneans became increasingly important as size class increased above 4-6 mm. The highest rate of daily feeding E. japonicusi took place during the day.

이 논문에서는 여러 곳에서 통용되고 있는 기존의 CW(Continuous-Wave) 바이오 레이더 송수신 모델을 수정한 새로운 송수신 모델을 제안한다. 최근에 심장 박동과 호흡을 검출하기 위해 CW 바이오 레이더를 이용해서 여러 연구 기관에서 연구가 진행되고 있다. 그러나 이 통용되고 있는 수신 모델을 이용해서 심장 박동을 검출하게 되면 여분의 위상 변이나 가우시안 잡음에 취약하고, 또한 인체 공학적으로 개념상 정확하지 못한 단점을 가지고 있다. 그러므로 이 논문에서 인체 공학상으로 정확한 수정된 CW 바이오 레이더 송수신 모델을 제안함으로써 여분의 위상 변이와 가우시안 잡음이 있는 환경뿐 아니라 다중 경로 환경에서 기존의 송수신 모델과의 심장 박동과 호흡 검출에 대한 성능을 비교 분석한다.

This research is of the rapid industrialization taking place resulting in the destruction of forests. The method that is implemented needs the vegetation to work well with the topsoil in order to restore the environment. In November the researcher collected a depth of 5 cm of topsoil from a well developed forest, after the fallen leaves were cleared. The results of the essential research are as follows : In the case of using the forest topsoil to plant trees latency seeds, during the early stages of tree planting, time is necessary for the desired vegetation to reach a similar state to the vegetation being restored. The results conclude that the best possible affect is obtained through a method utilizing seeded species. Utilizing forest topsoil, slopes that have been too damaged for trees to be planted can be sown with seeds. In addition the rearing of naturally-emerging species had a tendency to decline. When considering rearing naturally-emerging species to flourish in the topsoil, in the early stages of tree planting, the beginning foundation of sowing seeded species has to have a standard of about 1,000parts/$m^2$ This standard has been found to the most successful.
