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.

<P>We explored the transfer of a single-layered graphene membrane assisted by substrate adhesion. A relatively larger adhesion force was measured on the SiO<SUB>2</SUB> substrate compared with its van der Waals contribution, which is expected to result from the additional contribution of the chemical bonding force. Density functional theory calculations verified that the strong adhesion force was indeed accompanied by chemical bonding. The transfer of single-layered graphene and subsequent deposition of the dielectric layer were best performed on the SiO<SUB>2</SUB> substrate exhibiting a larger adhesion force. This study suggests the selection and/or modification of the underlying substrate for proper transfer of graphene as well as other 2D materials similar to graphene.</P>
Next-generation Neural Interfaces: From Fibers to Nanomaterials

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.

Iris dichotoma Pall. found on Daechung Island in Korea has been designated as an endangered species. To aid in conservation efforts of this species, this study investigated its germination characteristics and seed dormancy type. Four sets of seeds were incubated at different temperatures (4/1℃, 15/6℃, 20/10℃, and 25/15℃). One set of seeds was cold stratified (4 weeks at 4/1℃). The final germination rate and mean germination time showed that the optimal germination temperature was 25/15℃. Final germination rates were ~70%, showing no significant difference among temperature treatments. However, mean germination time were significantly different among all temperature treatments except for 4/1℃. Mean germination time for seeds with temperature treatments of 15/6℃, 20/10℃, and 25/15℃ were 3.2, 2.1, and 1.5 weeks, respectively. At 25/15℃, the mean germination time was half of that at 15/6℃. Seeds of I. dichotoma had fully developed embryos at the time of dispersal. No additional growth of the embryo was observed. Cold stratification did not affect the final germination rate or the mean germination time. This study shows that seeds of I. dichotoma have no physiological or morphological dormancy, unlike other members of the Iris genus known to have seed dormancy that needs a relatively high incubation temperature (≥25/15℃) for mass propagation to occur. These results will be useful for understanding ecophysiological mechanisms related to the species' habitat. They are also useful for mass propagation of I. dichotoma for the purpose of conserving this endangered species.

<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>
