본 연구에서는 지역사회 복지전달체계의 변화에 따른 마을복지계획 추진의 의미를 확인하고 해당 계획 수립과 관련된 실천적·정책적 과제들을 제안하고자 하였다. 이를 위하여 용인시 A동의 마을복지계획 수립의 전 과정을 관찰하였으며, 관련 전문가 및 실무자와의 지속적인 논의를 진행하였다. 본 사례는 지역 단체나 마을공동체 등의 자원이 부족한 읍면동에서 실제 마을복지계획이 추진될 경우에 당면하게 될 문제들을 제시하였다는 점에서 가치를 가진다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 마을복지계획은 읍면동 단위 복지 전달체계의 기능강화에 기반을 두고 있다. 둘째, 마을복지계획은 지역의 소규모 의제에 빠르게 대응하고 지역자원을 적극 활용하며 주민의 직접적인 참여를 기반으로 수행되는 특징을 가진다. 셋째, 마을복지 계획 추진단 구성과 실무 및 자문단 구성에 필요한 적정 수준의 지원이 요구된다. 넷째, 지역 내 전문 자원의 활용과 함께 주민들의 주체적인 참여를 활성화할 수 있는 방안들이 함께 모색되어야 한다. 이상의 연구결과를 바탕으로 다음의 제언을 하였다. 첫째, 마을복지계획 추진을 위해서는 읍면동 인적안전망의 활성화가 선행되어야 한다. 둘째, 시군구-읍면동 간의 협력 관계 형성 및 시군구 지역사회보장협의체의 기능 강화가 요구된다. 셋째, 지역 간 교류 협력과 주민 촉진자의 양성이 동반되어야 한다. The purpose of this study is to propose practical and policy tasks of Residents-driven Community Welfare Planning in Eup-Myeon-Dong by reviewing the process of establishing A-dong in Yongin-si. The results are as follows. First, the community welfare planning is based on reinforcing the function of the welfare delivery system at the level of Eup-Myeon-Dong. Second, the community welfare planning has the characteristics of responding to small-scale local agendas, utilizing various local resources, and requiring direct participation of residents. Third, it is necessary to support the composition of an activity group, working group, and advisory group for community welfare planning. Fourth, in order to establish a community welfare planning, it is necessary to utilize specialized resources in the community and encourage residents-led participation. The implications of the policy for community welfare and public-private cooperation are discussed based on the research results.

Background: Most patients with influenza recover spontaneously or following treatment with an anti-viral agent, but some patients experience pneumonia requiring hospitalization. We conducted a retrospective review to determine the incidence and risk factors of pneumonia in hospitalized patients with influenza A or B. Methods: A total of 213 patients aged 18 years or older and hospitalized with influenza between January 2012 and January 2015 were included in this study. A reverse-transcriptase polymerase chain reaction assay was used to detect the influenza A or B virus in the patientsc sputum samples. We collected demographic and laboratory data, combined coexisting diseases, and radiologic findings. Results: The incidence of pneumonia was higher in patients in the influenza A group compared to those in the influenza B group (68.6% vs. 56.9%), but this difference was not statistically significant. The presence of underlying respiratory disease was significantly associated with pneumonia in the influenza A group (adjusted odds ratio [OR], 3.975; 95% confidence interval [CI], 1.312±12.043; p=0.015). In the influenza B group, the white blood cell count (adjusted OR, 1.413; 95% CI, 1.053±1.896; p=0.021), platelet count (adjusted OR, 0.988; 95% CI, 0.978±0.999; p=0.027), and existence of an underlying medical disease (adjusted OR, 15.858; 95% CI, 1.757±143.088; p=0.014) were all significantly associated with pneumonia in multivariate analyses. Conclusion: The incidence of pneumonia was 65.7% in hospitalized patients with influenza A or B. The risk factors of pneumonia differed in hospitalized patients with influenza A or B.

Wide-Range Controllable n-Doping of Molybdenum Disulfide (MoS₂) through Thermal and Optical Activation

<P>Despite growing interest in doping two-dimensional (2D) transition metal dichalcogenides (TMDs) for future layered semiconductor devices, controllability is currently limited to only heavy doping (degenerate regime). This causes 2D materials to act as metallic layers, and an ion implantation technique with precise doping controllability is not available for these materials (<I>e</I>.<I>g</I>., MoS<SUB>2</SUB>, MoSe<SUB>2</SUB>, WS<SUB>2</SUB>, WSe<SUB>2</SUB>, graphene). Since adjustment of the electrical and optical properties of 2D materials is possible within a light (nondegenerate) doping regime, a wide-range doping capability including nondegenerate and degenerate regimes is a critical aspect of the design and fabrication of 2D TMD-based electronic and optoelectronic devices. Here, we demonstrate a wide-range controllable n-doping method on a 2D TMD material (exfoliated trilayer and bulk MoS<SUB>2</SUB>) with the assistance of a phosphorus silicate glass (PSG) insulating layer, which has the broadest doping range among the results reported to date (between 3.6 × 10<SUP>10</SUP> and 8.3 × 10<SUP>12</SUP> cm<SUP><B>-</B>2</SUP>) and is also applicable to other 2D semiconductors. This is achieved through (1) a three-step process consisting of, first, dopant out-diffusion between 700 and 900 °C, second, thermal activation at 500 °C, and, third, optical activation above 5 μW steps and (2) weight percentage adjustment of P atoms in PSG (2 and 5 wt %). We anticipate our widely controllable n-doping method to be a starting point for the successful integration of future layered semiconductor devices.</P><P><B>Graphic Abstract</B> <IMG SRC='http://pubs.acs.org/appl/literatum/publisher/achs/journals/content/ancac3/2015/ancac3.2015.9.issue-3/acsnano.5b00153/production/images/medium/nn-2015-00153b_0008.gif'></P><P><A href='http://pubs.acs.org/doi/suppl/10.1021/nn5b00153'>ACS Electronic Supporting Info</A></P>

Formation of Hexagonal Boron Nitride by Metal Atomic Vacancy-Assisted B–N Molecular Diffusion

Park, Seongjun,Lee, Jinyeong,Kim, Han Sol,Park, Jong-Bong,Lee, Kang Hyuck,Han, Sang A,Hwang, Sungwoo,Kim, Sang-Woo,Shin, Hyeon-Jin American Chemical Society 2015 ACS NANO Vol.9 No.1

<P>Because of the low solubility of N atoms in metals, hexagonal boron nitride (h-BN) growth has explained by surface reaction on metal rather than by penetration/precipitation of B and N atoms in metal. Here, we present an impressive pathway of h-BN formation at the interface between Ni and oxide substrate based on B-N molecular diffusion into Ni through individual atomic vacancies. First-principles calculations confirmed the formation energies of the h-BN layers on and under the metal and the probability of BN molecular diffusion in metal. The interface growth behavior depends on the species of metal catalysts, and these simulation results well support experimental results.</P>

To understand the mechanism underlying the function and dynamics of the nervous system or to treat neurological disorders, it is essential to develop the techniques capable of modulating and recording a diversity of signals employed by neurons. However, current approaches are limited in terms of effectiveness, side effects, non-specificity, and mechanical invasiveness. Naturally, there is a huge need for new devices or materials allowing for minimally invasive manipulation with monitoring of neural activity. My talk will introduce various complementary strategies to address these challenges: (1) Flexible and stretchable fiber-based probes for interfacing with the brain and spinal cord; (2) Biocompatible fiber scaffold to help the regeneration of neural tissue; (3) Wireless nanoparticle-based techniques for deep brain stimulation. These technologies enabling the interrogation with neural circuits across their diverse signaling modalities without inducing a foreign-body reaction helps the study of information processing as well as pathologies of the nervous system.

Temporal change of upper-crustal _{V P} / _{V S} ratios with volcanic evolution in Redoubt Volcano

Park, Seongjun,Hong, Tae-Kyung,Buurman, Helena Elsevier 2018 Physics of the earth and planetary interiors Vol.282 No.-

<P><B>Abstract</B></P> <P>Volcanic activities accompany changes in the physical and chemical properties of the medium. The ratio between <I>P</I>- and <I>S</I>-wave velocities, <SUB> V P </SUB> / <SUB> V S </SUB> , is sensitive to the medium property changes. We investigate temporal variations of the <SUB> V P </SUB> / <SUB> V S </SUB> ratios in the upper crust around Redoubt Volcano in the 1989–2014 time period using the traveltimes of local earthquakes. The <SUB> V P </SUB> / <SUB> V S </SUB> ratios reached ∼ 2.0 immediately prior to the 1989–1990 and 2009 eruptions. These high <SUB> V P </SUB> / <SUB> V S </SUB> ratios may be associated with partial melts in the edifice. The <SUB> V P </SUB> / <SUB> V S </SUB> ratios rapidly decreased to ∼ 1.7 during the 1989–1990 and 2009 eruptions due to decreasing temperatures, fluids, and pore pressures and increasing effective stresses after melt eruptions and gas emission. The change rates of the <SUB> V P </SUB> / <SUB> V S </SUB> ratios showed evident spatial distributions. The <SUB> V P </SUB> / <SUB> V S </SUB> ratios increased at a rate of 0.025 ( ± 0.003) yr<SUP>−1</SUP> below the 2009 vent during the inter-eruption period between the 1989–1990 and 2009 eruptions due to an increase in the temperature, which may be associated with the recharge of the magma in the lower crust. The increase rate of the <SUB> V P </SUB> / <SUB> V S </SUB> ratios was as low as 0.005 ( ± 0.001) yr<SUP>−1</SUP> in the regions located away from the eruption site. The <SUB> V P </SUB> / <SUB> V S </SUB> ratios appear to have increased consistently at a rate of 0.017 ( ± 0.004) yr<SUP>−1</SUP> since the 2009 eruption.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The upper-crustal Vp/Vs ratios changed with volcanic evolution in Redoubt Volcano. </LI> <LI> The Vp/Vs ratios decreased rapidly from 2.0 to 1.7 during the eruptions. </LI> <LI> The Vp/Vs ratios change gradually in inter-eruption periods. </LI> </UL> </P>
