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.

In this study, we develop that Location Recommending System using personal emotion information based on Collaborative Filtering. Previous Location Recommending System recommended a place visited by the user of the rating or the pattern of location for the user place. These systems are not high user satisfaction because that dose not consider the user status or have not objectively the information. Using user's personal emotion information to recommend a high-affinity users who have visited the place felt similar emotions objectively can improve user satisfaction with the place. In this study, a user using a mobile application directly register the recognized emotion information using the current position and bio-signal, and using the registered information measuring the similarity of user with a similarity emotion, predicts a preference for the place it is recommended to emotional place. The system consists of a user interface, a database, a recommendation module.

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.

The paper proposes a new signal model which is revised from the commonly used signal model. Recently, many research institutions had a research about CW bio-radar for detecting he heartbeat and respiration. However, when the bio-radar detects the heartbeat using the previous signal model, the bio-radar has a disadvantage of weakness about he residual phase and AWGN. Also, the model is inappropriate in ergonomics because this signal model supposes hat the heart and lung are located at a same place. In this paper, the modified signal model, which is appropriate n ergonomics, is proposed. This paper analyzes and compares with the performance for detecting the heartbeat and respiration using the previous model and revised model in AWGN and multi-path environment.

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.
