Artificial Intelligence-Based Business Communication: Application for Recruitment and Selection
Mina Son,Hyeonju Lee,장혜정 한국경영커뮤니케이션학회 2019 Business Communication Research and Practice Vol.2 No.2
Objectives:Artificial intelligence (AI) has become an increasingly important issue with the rise of the Fourth Industrial Revolution. In human resource (HR) management, one of the most important tasks is the recruitment of qualified employees. This paper examines inAIR (AI for Recruiting), a recent recruitment integration solution, to explore how AI technology enables new communication channels in the recruitment process. Methods:The inAIR is an online system that manages the recruitment process, which includes but is not limited to document reviews, personality tests, interview screenings, and judgement suggestions. The AI-based interview step demonstrates how inAIR uses AI and machine learning. Results:The value of the AI interview is that it maximizes the communication channels between the applicants and the HR manager. While the HR team can now receive immediate results equivalent to those usually reached by interviewing thousands of applicants, applicants can still convey their passion, experience, and abilities beyond what has been expressed in their documents. The inAIR is an efficient tool in terms of the time required: An applicant takes about an hour to complete an AI interview, and the system takes no more than an hour to analyze all the data from thousands of applicants. Conclusions:AI has been adopted in the recruitment process as well as processes that evaluate employee experience, train employees in various job skills, and make decisions necessary for business management. With the development of the Internet and AI technology, the communication channels between applicants and HR managers have been expanded, allowing a variety of processes to run much more efficiently.

<P>A bioassay-guided investigation in conjunction with chemical screening led to the isolation of three new glycosides, ulleungoside (1), 2-methylaminobenzoyl 6-deoxy-alpha-L-talopyranoside (2), and naphthomycinoside (3), along with three known secondary metabolites (5-7) from Streptomyces sp. KCB13F030. Their structures were elucidated by detailed NMR and MS spectroscopic analyses. Absolute configurational analysis of the sugar units based on the magnitudes of the coupling constants, NOESY correlations, chemical derivatization, and optical rotation measurements revealed that compounds 1-3 and 5 incorporate the rare deoxyhexose 6-deoxy-alpha-L-talopyranose. The absolute configuration of a polyketide extender unit of 3 was determined by applying the J-based configuration analysis and modified Mosher's method. Ulleungoside (1) and naphthomycin A (7) showed activity. Further bioevaluation revealed that compounds 1 and cell lines, and compounds 5 and 6, which are members of the 2 plying the J-based configuration analysis and modified Mosher's in vitro inhibitory effects against indoleamine 2,3-dioxygenase 7 had moderate antiproliferative activities against several cancer piericidin family, induced autophagosome accumulation.</P>

<P>Analysis of the genome sequence of <I>Streptomyces</I> sp. KCB13F003 showed the presence of a cryptic gene cluster encoding flavin-dependent halogenase and nonribosomal peptide synthetase. Pleiotropic approaches using multiple culture media followed by LC-MS-guided isolation and spectroscopic analysis enabled the identification of two new chlorinated cyclic hexapeptides, ulleungmycins A and B (<B>1</B> and <B>2</B>). Their structures, including absolute configurations, were determined by 1D and 2D NMR techniques, advanced Marfey’s analysis, and GITC derivatization. The new peptides, featuring unusual amino acids 5-chloro-<SMALL>l</SMALL>-tryptophan and <SMALL>d</SMALL>-homoleucine, exhibited moderate antibacterial activities against Gram-positive pathogenic bacteria including methicillin-resistant and quinolone-resistant <I>Staphylococcus aureus</I>.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jnprdf/2017/jnprdf.2017.80.issue-11/acs.jnatprod.7b00660/production/images/medium/np-2017-00660j_0005.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/np7b00660'>ACS Electronic Supporting Info</A></P>
Microalgae dewatering based on forward osmosis employing proton exchange membrane
Son, Jieun,Sung, Mina,Ryu, Hoyoung,Oh, You-Kwan,Han, Jong-In Elsevier Applied Science 2017 Bioresource technology Vol.244 No.1
<P><B>Abstract</B></P> <P>In this study, electrically-facilitated forward osmosis (FO) employing proton exchange membrane (PEM) was established for the purpose of microalgae dewatering. An increase in water flux was observed when an external voltage was applied to the FO equipped with the PEM; as expected, the trend became more dramatic with both concentration of draw solution and applied voltage raised. With this FO used for microalgae dewatering, 247% of increase in flux and 86% in final biomass concentration were observed. In addition to the effect on flux improvement, the electrically-facilitated FO exhibited the ability to remove chlorophyll from the dewatered biomass, down to 0.021±0015mg/g cell. All these suggest that the newly suggested electrically-facilitated FO, one particularly employed PEM, can indeed offer a workable way of dewatering of microalgae; it appeared to be so because it can also remove the ever-problematic chlorophyll from extracted lipids in a simultaneous fashion.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Electrically-facilitated forward osmosis was established for microalgae dewatering. </LI> <LI> Proton exchange membrane was employed for the suggested forward osmosis module. </LI> <LI> Dewatering flux and final biomass concentration was significantly increased. </LI> <LI> Chlorophyll was successfully removed from the dewatered biomass. </LI> <LI> Both microalgae dewatering and chlorophyll removal were achieved simultaneously. </LI> </UL> </P>

<P>The advances of genomic sequence analyses and genome mining tools have enabled the exploration of untapped microbial natural products. Through genome mining studies to discover cryptic natural products, we found biosynthetic genes encoding a new lasso peptide in the genome sequence of a soil bacterium, <I>Streptomyces</I> sp. KCB13F003 isolated from Ulleung Island (a small volcanic island), Korea. The production and purification of the encoded peptide, named ulleungdin, were achieved by optimizing the culture conditions followed by LC-MS-targeted isolation. Structure elucidation was performed by NMR spectroscopic and MS spectrometric analyses and chemical means (Marfey’s and GITC derivatizations), proving ulleungdin to be a new 15-mer class II lasso peptide with a threaded structure. Biological evaluation with the cell invasion assay and time-lapse cell tracking analysis revealed that ulleungdin has significant inhibitory activities against cancer cell invasion and migration.</P> [FIG OMISSION]</BR>

<P>Two novel cyclic depsipeptides, ulleungamides A (1) and B (2), were isolated from cultures of terrestrial Streptomyces sp. Their structures were determined by analyses of spectroscopic data and various chemical transformations, including modified Mosher's method, advanced Marfey's method, PGMF,, GITC derivatizations, and Snatzke's method. Ulleungamides were determined to be a new class of peptides bearing unprecedented units, such as 5-hydroxy-6-methyl-2,3-dehydropipecolic acid, 4,5-dihydroxy-6-methyl-2,3-dehydropipecolic acid, and amino-linked 2-isopropylsuccinic acid. Ulleungamide A displayed growth inhibitory activity against Staphylococcus aureus and Salmonella typhimurium without cytotoxicity.</P>

<P>New glycosylated 26-membered triene macrolides catenulisporolides, the first polyketide metabolites from <I>Catenulispora</I> species, were obtained by targeting slow-forming colonies on selection agar plates and applying long-term cultivation. Their structures, including the full stereochemistry, were defined by comprehensive spectroscopic and chemical methods and confirmed by bioinformatics analysis. Analysis of the genome sequence revealed the responsible biosynthetic gene cluster spanning ∼160 kbp, and feeding experiments with isotope-labeled precursors showed that isovaleric acid acts as a rare starter unit. Catenulisporolides exhibited antimalarial activities against resistant strains of <I>Plasmodium falciparum</I>, and enhanced activity was observed in semisynthetic derivatives.</P> [FIG OMISSION]</BR>
