Background:In crisis intervention sites such as infectious disease disasters,counselors are repeatedly exposed,directly or indirectly,to the traumatic experiences of *** counseling has a negative effect on coun-selors,which can eventually interfere with the counseling process for disaster ***,exploring and understanding the experiences of counselors is necessary to ensure that qualitative counseling for disaster victims can be continuously and efficiently ***:This study investigated the experiences of counselors who participated in mental health counseling as psychological support for victims of the COVID-19 disaster in ***:This is a qualitative ***:The study participants comprised 18 counselors who had mental health professional qualifications of level 2 or higher and who had provided mental health counseling for COVID-19 confirmed cases and quarantined ***:Data were collected using focus group interviews from February 21 to May 29,*** duration of each interview was 60–90 min,and the data were analyzed using content ***:Thefinal theme was“Continuing to walk this road anytime,anywhere.”The par-ticipants’experiences were identified in four sub-themes:“being deployed to unprepared counseling,”“encoun-tering various difficulties,”“feeling full of meaning and value,”and“hoping to become a better counselor.”Conclusions:In order to continuously provide qualitative counseling in case of an infectious disease disaster such as COVID-19,it is important to develop a qualification and competency strengthening program through educa-tion and training to secure the crisis intervention expertise of counselors according to the characteristics of the *** addition,a psychological support manual for each disaster should be prepared at the national level according to the type of disaster.

The outstanding tribological performance of transition metal dichalcogenides(TMDs)is attributed to their unique sandwich microstructure and low interlayer shear *** advantageous structure allows TMDs to demonstrate exceptional friction reduction ***,the incorporation of TMDs and amorphous carbon(a-C)in multi-layer structures shows excellent potential for further enhancing tribological and anti-oxidation *** carbon,known for its high ductility,chemical inertness,and excellent wear resistance,significantly contributes to the overall performance of these multi-layer *** gain an in-depth understanding of the tribological mechanism and evolution of TMDs’multi-layer coatings,a dual in-situ analysis was carried out using a tribometer equipped with a 3D laser microscope and a Raman *** innovative approach allowed for a comprehensive evolution of the tribological,topographical,and tribochemical characteristics of both single-layer WS_(2)and multi-layer WS_(2)/C coatings in real *** findings from the dual in-situ tribotest revealed distinct failure characteristics between the single-layer WS_(2)coating and the multi-layer WS_(2)/C *** single-layer WS_(2)coating predominantly experienced failure due to mechanical removal,whereas a combination of mechanical removal and tribochemistry primarily influenced the failure of the multi-layer WS_(2)/C *** tribological evolution process of these two coatings can be classified into four stages on the basis of their tribological behavior:the running-in stage,stable friction stage,re-deposition stage,and lubrication failure *** stage represents a distinct phase in the tribological behavior of the coatings and contributes to our understanding of their behavior during sliding.

Neural Regeneration Research 2015年第6期10卷 878-880页

作者： eun-jung kim Seong-Woon Yu Department of Brain and Cognitive Science Daegu Gyeongbuk Institute of Science and Technology (DGIST)

The normal development and optimal functioning of the brain requires a vigilant immune surveillance system to detect and remove potential risk factors and prevent infection and tissue damage. Microglia are the resident immune cells and the frontline defenders responsible for the immune response of the brain. Resting microglia possess a ramified morphology with numerous thin processes that continuously sample the environment. In response to inflammatory signals, microglia become activated and transform their morphology into a thick, amoeboid-like shape. Activated microglia proliferate, tolerate to sites of iniurv,

Effects of Polymeric Stabilizers on the Synthesis of Gold Nanoparticles

引用

Journal of Materials Science & Technology 2014年第2期30卷 107-111页

作者： eun jung kim Jeong Hyun Yeum Jin Hyun Choi Department of Advanced Organic Materials Science and Engineering Kyungpook National University Department of Bio-fibers and materials Science Kyungpook National University

Gold nanoparticles （AuNPs） stabilized with sodium alginate （SA）, glycol chitosan （GC）, polyvinyl alcohol （PVA）, and polyethyleneimine （PEI） were synthesized in aqueous solutions at room temperature. Different sizes and size distributions of AuNPs were obtained according to the polymeric stabilizers. The mean particle diameters of AuNPs synthesized with GC and PVA as stabilizers were about 5.1 and 5.3 nm, respectively, while those of AuNPs stabilized with SA and PEI were 8.4 and 10.8 nm, respectively. When SA was used, relatively large particles aggregated to form large clusters. In the case of GC, a number of small particles built up large clusters. When PVA was used, the size and the number of nanoperticles were estimated small with a low weight content of Au. For this reason, the PVA-stabilized AuNPs formed clusters with a small hydrodynamic size. The AuNPs synthesized in the aqueous solution of PEI without a reducing agent, sodium borohydride, were uniform in size and formed the smallest nanoclusters （67.4 nm）. In this case, the highest Au content was obtained. Sufficiently grown nanoparticles with a high Au content and a limited hydrodynamic size are considered to be suitable for a variety of applications.
