Many fish species are known to associate with echinoids. We studied the frequency of fishes associatingwith the diadematid Black Longspine Urchin Diadema setosum and Banded Sea Urchin Echinothrix cal amaris in the Phi Phi Islands of southwestern Thailand during July 17e20, 2022. A total of 1373 fishindividuals of 20 species associated with 1157 D. setosum, and 11 fish individuals of seven speciesassociated with 76 E. calamaris. The proportion of fish individuals per echinoid host was 8.2 times higherfor longer-spined D. setosum (1.19) than for E. calamaris (0.14), and the proportion of echinoids hostingone or more fish was 2.5 times higher for D. setosum (22.9%) than for E. calamaris (9.2%), supporting thehypothesis that fishes prefer to associate with echinoid species with the longest spines, which potentiallyprovide more protection against predators. All fishes associating with echinoids were small (<10 cm);most were adults, but for some species, all were juveniles. All fishes were facultative associates ofechinoids. Only three fish species had been previously reported associating with D. setosum and nonewith E. calamaris; the remaining fish species represent new records of association, including 17 forD. setosum and seven for E. calamaris.

인삼식물에 관한 연구 (Ⅰ) - 미국인삼 사포닌 및 그 비당체

The saponins of two- and four-year-old American ginseng plants (Panax quinquefolium L.) (Araliaceae) collected in July and September were studied. American ginseng saponins (panaquilins) differ from Korean ginseng (Panax ginseng C.A. MEYER) saponins (ginsenosides). The American ginseng saponins separated and named were panaquilins A, B, C, D, E-1, E-2, E-3, G-1, G-2, (c) and (d). One-dimensional thin-layer chromatography did not completely separate panaquilin mixture and was subject to misinterpretation. The panaquilins were more accurately separated and identified by the two-dimensional thin-layer method established. Some differences in American ginseng saponins were dependent upon the plant age, time of collection, and part extracted. The American ginseng sapogenin components are panaxadiol (panaquilins B and C), oleanolic acid (panaquilin D) and panaxatriol (panaquilin G-1). The panaquilins E-1, E-2 and E-3 mixture contained both panaxadiol and panaxatriol. The genins of panaquilins A, (c), (d) and G-2 were not identified. In addition, β-sitosterol and stigmasterol were identified from the root ether extracts.

Financial News and Client Stress

John E. Grable,Sonya L. Britt 한국FP학회 2012 Financial Planning Review Vol.5 No.3

재무설계사는 고객과 신뢰감 있는 관계를 형성하기 위해서 전문역량과 의사소통기술을 보여주어야 한다. 이와 더불어 최근에는 고객의 스트레스를 관리하여 주는 것이 고객과 설계사간의 관계를 향상시키는데 기여할 수 있다는 증거가 나타나고 있다. 본 연구는 금융뉴스는 고객의 스트레스와 관계가 있는가라는 재무설계현장에서 자주 제기되고 있는 문제를 다루었다. 본 연구를 통해 실시된 실험을 통하여 나타난 연구결과는 고객 앞에서는 CNBC, 블룸버그, 팍스경제뉴스 등과 같은 금융뉴스를 끄라고 제안한다. 금융뉴스는 스트레스를 증가시키는데 특히 남성에게 더욱 그러하다. 주식시장의 상승소식과 같은 긍정적인 금융뉴스는 스트레스지수를 가장 높게 만드는 뉴스였다. 긍정적 금융뉴스는 후회감을 야기시키는 것으로 사료된다. Building client?planner relationships based on trust requires financial planners to demonstrate both technical competence and communication skills. Emerging evidence also suggests that managing client stress can lead to better client-planner interactions. This paper addresses a common question asked within the field of financial planning; namely, is financial news associated with client stress. Results from this experimental study suggest that financial planners should opt to turn off financial news programs, such as CNBC, Bloomberg, and Fox Business News in the presence of clients. Financial news was found to increase stress levels, particularly among men. Positive financial news(e.g., reports of bullishness in the stock market) created the highest levels of stress. It was hypothesized that positive financial news may trigger regret among some people.

한국기업과 미국기업의 경쟁정보활동에 관한 탐색적 비교연구

김광수,John E. Prescott,Ravi Madhavan 한국국제경영관리학회 2006 국제경영리뷰 Vol.10 No.3

본 연구에서는 제도적 환경이 현저하게 다른 한국기업과 미국기업의 경쟁정보활동에 관한 탐색적 비교분석을 통하여 경쟁정보활동에 있어 양국기업 간의 차이점과 유사점을 파악한다. 연구결과에 따르면, 경쟁정보활동 관련 모든 핵심영역(프로세스, 방법, 인프라 등)에서 양국기업 간에 현저한 차이가 존재한다. 예를 들어, 정보수집과 관련하여, 한국기업은 미국기업에 비해 인맥과 비공개정보를 더 많이 활용하는가하면, 미국기업은 한국기업에 비해 신문, 인터넷, 보고서 등 각종매체와 공개정보를 더 많이 활용한다. 정보사용자에게 정보를 전달하기 위해 한국기업은 미국기업에 비해 보고서를, 미국기업은 한국기업에 비해 e-메일을 더 자주 활용한다. 한국기업보다 미국기업이 경쟁정보활동을 수행함에 있어 기업 내부적으로 더 개방적인 분위기이다. 또한 미국기업에 비해 한국기업의 구성원들이 경쟁정보활동을 비윤리적으로 보는 경향이 크다. 이와 같은 연구결과는 미국의 경쟁정보 이론 및 기법의 국내 도입을 위한 중요한 시사점을 제공할 뿐만 아니라, 국내 상황에 적합한 경쟁정보 이론 및 기법 개발을 요구한다. This research explores the differences in competitive intelligence practices between Korean and American companies. The results of this research reveal significant differences between the two groups of companies in all major areas of competitive intelligence, including its process, methods, and infrastructure. For example, Korean companies utilize personal connections to gather undisclosed information more than American companies, while American companies utilize various media, such as the internet and newspapers, to gather disclosed information more than Korean companies. To deliver information to relevant users, Korean companies rely on reports more than their counterparts, and American companies rely on e-mails more than their counterparts. American firms are internally more open in conducting competitive intelligence activities than Korean companies. The organizational members of Korean firms have a greater tendency to view competitive intelligence as somewhat unethical than their counterparts. These results suggest some important implication for the introduction of American CI theories and methods to local Korean companies, and they also call for a development of CI theories and methods tailored to the conditions of local companies.

Seeking the most powerful and practical real-world sorbents for gaseous benzene as a representative volatile organic compound based on performance metrics

Szulejko, Jan E.,Kim, Ki-Hyun,Parise, John Elsevier 2019 Separation and purification technology Vol.212 No.-

<P><B>Abstract</B></P> <P>To assess the best sorbents available in real-world treatment of airborne volatile organic compounds (VOCs), we explored four sorbent performance metrics (10% breakthrough volume, space velocity, regeneration cycles, and cost) against benzene, a representative VOC, using well-known sorbents in the partial pressure (P<SUB>benzene</SUB>) range 0.01 – 1 Pa. Accordingly, some common materials (e.g., activated carbons) outperformed novel materials like MOFs. The performance of MOFs was often exaggerated as data were generally collected under unrealistic P<SUB>benzene</SUB> (e.g., >5,000 Pa). The use of metrics appropriate to real-world conditions is thus critical for selecting sorbents.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Performance of sorbents in real-world treatment of VOC is important for AQM purposes. </LI> <LI> Metrics were selected as breakthrough volume, space velocity, regeneration cycles, and cost. </LI> <LI> Sorbent performance metrics were checked for benzene in the partial pressure 0.01–1 Pa. </LI> <LI> Some common materials (e.g., activated carbons) have the potential to outperform others. </LI> <LI> The use of metrics appropriate to real-world conditions is critical for selecting sorbents. </LI> </UL> </P>

Ligand Accessibility and Bioactivity of a Hormone–Dendrimer Conjugate Depend on pH and pH History

Kim, Sung Hoon,Madak-Erdogan, Zeynep,Bae, Sung Chul,Carlson, Kathryn E.,Mayne, Christopher G.,Granick, Steve,Katzenellenbogen, Benita S.,Katzenellenbogen, John A. American Chemical Society 2015 JOURNAL OF THE AMERICAN CHEMICAL SOCIETY - Vol.137 No.32

<P>Estrogen conjugates with a polyamidoamine (PAMAM) dendrimer have shown remarkably selective regulation of the nongenomic actions of estrogens in target cells. In response to pH changes, however, these estrogen–dendrimer conjugates (EDCs) display a major morphological transition that alters the accessibility of the estrogen ligands that compromises the bioactivity of the EDC. A sharp break in dynamic behavior near pH 7 occurs for three different ligands on the surface of a PAMAM-G6 dendrimer: a fluorophore (tetramethylrhodamine [TMR]) and two estrogens (17α-ethynylestradiol and diphenolic acid). Collisional quenching and time-resolved fluorescence anisotropy experiments with TMR–PAMAM revealed high ligand shielding above pH 7 and low shielding below pH 7. Furthermore, when the pH was cycled from 8.5 (conditions of ligand–PAMAM conjugation) to 4.5 (e.g., endosome/lysosome) and through 6.5 (e.g., hypoxic environment) back to pH 8.5, the 17α-ethynylestradiol– and diphenolic acid–PAMAM conjugates experienced a dramatic, irreversible loss in cell stimulatory activity; dynamic NMR studies indicated that the hormonal ligands had become occluded within the more hydrophobic core of the PAMAM dendrimer. Thus, the active state of these estrogen–dendrimer conjugates appears to be metastable. This pH-dependent irreversible masking of activity is of considerable relevance to the design of drug conjugates with amine-bearing PAMAM dendrimers.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/jacsat/2015/jacsat.2015.137.issue-32/jacs.5b05952/production/images/medium/ja-2015-05952x_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/ja5b05952'>ACS Electronic Supporting Info</A></P>
