이 글은 소설가 김소진의 문학세계를 조망하여 1960년대 이후의 원체험을 가진 지식인이 1990년대에 이르러 나타난 현대성과 그 징후에 대응하는 방식을 살펴보고 이를 통해 그의 문학세계가 지닌 의미를 보다 확장시키기 위해 쓰여졌다. 본고에서는 김소진의 소설이 원체험을 바탕으로 “삶의 총체적 서사”를 그려나가고 있다고 판단하였으며 그의 작품을 원체험의 세계, 현실세계, 가능세계 등 세 가지의 유형으로 분류하여 살펴보고자 하였다. 그가 ‘밥풀때기’를 집중적으로 조명하려고 했던 것은 사회의 주변부에 머물러 있던 그들을 역사의 일부로 해석하고자 하였기 때문이다. 김소진은 지식인의 입장이면서도 원체험을 통해 그들을 닮아가는 과정에서 경계인에 있음을 인식하였다. 또한 거대담론의 시대가 지났음을 확인한 그가 현실 세계에 순응하는 모습을 보였던 것은 ‘살아간다’는 명제의 중요성을 인식했던 것으로 볼 수 있으며 이를 통해 원체험과 현실세계를 성공적으로 접합시켜 의미화에 도달했다고 볼 수 있다. This article expands the meaning of Kim So-jin’s literary world by examining this world and how intellectuals with original experiences since the 1960s responded to modernity and signs that appeared in the 1990s. Kim So-jin’s novels were based on the original experiences and are thought to draw “the total narrative of life.” We investigated his works by classifying them into the following types: the world of original experience, the real world, and the possible world. Kim Sojin intended to emphasize “the rice grains” in society because he wanted to interpret them as a part of history, as people who still remain on the periphery of society. Kim So‐jin recognized that, because he was also an intellectual, he partly resembled them through his original experiences. Furthermore, he confirmed that the age of the grand discourse was over, and he showed his adaptation to the real world in his recognition of the importance of the proposition of “living.” Through this, it can be said that he reached the signification by successfully connecting original experiences with the real world.
Highly Stable and Effective Doping of Graphene by Selective Atomic Layer Deposition of Ruthenium
Kim, Minsu,Kim, Ki-Ju,Lee, Seung-Joon,Kim, Hyun-Mi,Cho, Seong-Yong,Kim, Min-Sik,Kim, Soo-Hyun,Kim, Ki-Bum American Chemical Society 2017 ACS APPLIED MATERIALS & INTERFACES Vol.9 No.1
<P>The sheet resistance of graphene synthesized by chemical vapor deposition is found to be significantly reduced by the selective atomic layer deposition (ALD) of Ru onto defect sites such as wrinkles and grain boundaries. With 200 ALD cycles, the sheet resistance is reduced from similar to 500 to <50 Omega/sq, and the p-type carrier density is drastically increased from 10(13) to 10(15) cm(-2). At the same time, the carrier mobility is reduced from similar to 670 to less than 100 cm(2) V-1 s(-1). This, doping of graphene proved to be very stable, with the electrical properties remaining unchanged over eight weeks of measurement. Selective deposition of Ru on defect sites also makes it possible to obtain a grapherie film that is both highly transparent and electrically conductive (e.g., a sheet resistance of 125 Omega/sq with 92% optical transmittance at 550 nm). Highly doped graphene layers achieved by Ru ALP are therefore expected to provide a-viable basis for transparent conducting electrodes.</P>

Indole is an interspecies and interkingdom sig-naling molecule widespread in different environmental compartment. Although multifaceted roles of indole in dif-ferent biological systems have been established, little infor-mation is available on the microbial utilization of indole in the context of combating odor emissions from different types of waste. The present study was aimed at identifying novel bacteria capable of utilizing indole as the sole carbon and energy source. From the selective enrichment of swine waste and cattle feces, we identified Gram-positive and Gram-negative bacteria belonging to the genera Arthrobacter and Alcaligenes. Bacteria belonging to the genus Alcaligenes showed higher rates of indole utilization than Arthrobacter. Indole at 1.0 mM for growth was completely utilized by Alcaligenes sp. in 16 h. Both strains produced two interme-diates, anthranilic acid and isatim, during aerobic indole metabolism. These isolates were also able to grow on several indole derivatives. Interestingly, an adaptive response in terms of a decrease in cell size was observed in both strains in the presence of indole. The present study will help to explain the degradation of indole by different bacteria and also the pathways through which it is catabolized. Furthermore, these novel bacterial isolates could be potentially useful for the in situ attenuation of odorant indole and its derivatives emitted from different types of livestock waste.

Background: This study was conducted to identify the success rate for smoking cessation over time after participation in a therapeutic smoking cessation camp, and to identify how participant characteristics, including a supportive workplace environment for smoking cessation (SWESC), affect the success rate for smoking cessation. Methods: In all, 296 participants at smoking cessation camps in Ulsan between 2015 and 2020 were investigated. The success rates of smoking cessation after weeks 4, 6, 12, and 24 at camp were investigated. The participants were grouped as workers with an SWESC, and workers without an SWESC, and variables (age, education, household income, marital status, drinking, exercise, body mass index, morbidity, job, number of counseling sessions, cigarettes smoked per day and smoking initiation age) were investigated. Multiple logistic regression analysis was conducted at each time point. In addition, Cox regression analysis was performed to evaluate the variables affecting the success rate for smoking cessation over time. Results: The smoking cessation success rate of workers with an SWESC at week 24 (90.7%) was higher than that for workers without an SWESC (60.5%). Multiple logistic regression was performed to determine the relationship between each variable and the success rates for smoking cessation at week 6, 12, and 24. SWESC was confirmed as significant (p < 0.05) variables for increased success rate for smoking cessation at all 3 time points. After adjusting for all variables, the Cox proportional hazards survival analysis showed a hazard ratio of 6.17 for SWESC (p < 0.001,; 95% confidence interval: 3.08–12.38). Conclusions: At a professional treatment smoking cessation camp, participants with an SWESC showed a significantly higher success rate for smoking cessation. Supportive workplace environment for workers’ health is expected to be an important factor for smoking cessation projects as well as other health promotion projects at workplace.

Kim, Kyeong Nam,Jung, Yun Kyung,Chun, Jinsung,Ye, Byeong Uk,Gu, Minsu,Seo, Eunyong,Kim, Seongsu,Kim, Sang-Woo,Kim, Byeong-Su,Baik, Jeong Min Elsevier 2016 Nano energy Vol.26 No.-
<P><B>Abstract</B></P> <P>Developing a successful strategy to maximize the surface charge density is crucial to speed-up the commercialization success of triboelectric nanogenerator. Here, for the first time, the fabrication of positive triboelectric material to donate electrons efficiently to dielectrics is reported, by increasing the stretchability for the uniform contact and by introducing a functional group for the surface potential control. A highly stretchable and conductive film with Ag nanowires and PDMS was fabricated as a base material, in which the portion of nanowires exposed above the embedding surface should be accurately controlled. In specific, positively charged 4-(dimethylamino)pyridine (DMAP) coated Au nanoparticles, prepared by phase transfer method, are coated. The DMAP lowers the effective work function of the nanoparticles by a permanent dipole induced at the DMAP-Au interface and enhances the electron transfer to the dielectrics, confirmed by the Kelvin probe force microscope measurement. The designed nanogenerator gives an output performance up to 80V and 86μA, and 2.5mW in output power, 2.5 times enhancement compared with the conventional TENG. With the integration with AC to DC converting circuit and buck-boost circuit, the nanogenerator produces a constant voltage of 2.6V. The wireless sensing system, which operates the remote controller, were also demonstrated, turning on a siren.</P> <P><B>Highlights</B></P> <P> <UL> <LI> A positive triboelectric material to donate electrons efficiently to dielectrics is developed. </LI> <LI> The keynote is to increase the stretchability and to introduce a functional group. </LI> <LI> It was proven to be effective for the uniform contact and surface potential control. </LI> <LI> The TENG gave an output performance up to 80 V and 86 μA, and 2.5 mW in output power. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>

Dongkyo Kim,Namtae Kim,Sungwoo Kim,Chan-lan Kim,Ik Soo Jeon,YeoungGyu Ko,Minsu Kim 한국수정란이식학회 2018 한국수정란이식학회 학술대회 Vol.2018 No.11
The ovum pick up(OPU) technique can be used to produce embryos after in vitro culture of ovarian oocytes, can be used for early securement for effective herd early proliferation and excellent Hanwoo genetic resources, It is attracting attention as a very important technique for establishing technology. In addition to in vitro culture techniques, the number of oocytes retrieved depends on the environment and timing of the OPU. This study was conducted to compare and examine seasonal effect to the differences in the number of recovered oocytes, recovery rate and embryo development rate using Korean cattle kept in animal genetic resource research center by OPU technique. The grade of COCs was evaluated by microscopic examination. Grade A had 3 or more layers of cumulus cell and compact cytoplasm. Grade B had 1~3 layers of cumulus cell and compact cytoplasm. Grade C had 1 layers cumulus cell and compact cytoplasm. Grade D was denuded oocyte and poor cytoplasm. The recovery rate was 47.8±3.4% in summer (June to August) and 51.6±3.8% in autumn (September to October). The number of oocytes was 5.7±0.6 in summer and 5.2±0.7 in autumn. Oocyte grade A and B was 46.2%±6.3% in summer and 51.1±5.0% in autumn. The cleavage rate was 46.1±7.1% in summer and 65.0±11.3% in autumn. Blastocyst development rate was 19.9±9.4% in summer and 29.0±8.7% in autumn. There was no difference the recovery rate of oocytes and the number of embryos between summer and autumn. Cleavage rate and blastocyst rate of autumn was higher than summer. we will investigate to study the appropriate method for the production of Hanwoo embryos and the systematic comparison.
