Microfluidics based on nanobio sensors technologies can provide convenient and accurate diagnosis tools. In this talk, we present recent developments of nanobio sensors & diagnosis chip using microfluidics, with special emphasis on disposable plastic devices format. In detail, we overview of the common methods used in the fabrication of polymer microfluidic systems, including replica and injection mold-ing. Also we explain the different methods by which on-chip operations—such as the pumping and valving of fluid flow, the mixing of different reagents, and the separation and detection of different biochemical species implemented in a microfluidic format. Finally, a few select biotechnological applications of microfluidics are presented to illustrate both the utility of this technology and its potential applications with insect models in the near future.

About 10 percent of quasars are known to exhibit deep broad absorption troughs blueward of prominent permitted emission lines, which are usually attributed to the existence of outflows slightly above he accretion disk around the supermassive black hole. Typical widths up to 0.2c of these absorption roughs indicate the velocity scales in which special relativistic effects may not be negligible. Under he assumption of the ubiquity of the broad absorption line region in quasars, the broad emission line flux will exhibit Thomson scattered components from these fast outflows. In this paper, we provide our Monte Carlo calculation of linear polarization of singly Thomson scattered line radiation with the careful considerations of special relativistic effects. The scattering region is approximated by a collection of rings that are moving outward with speeds υ =cβ < 0.2c near the equatorial plane, and the scattered line photons are collected according to its direction and wavelength in the observer's rest frame. We find that the significantly extended red tail appears in the scattered radiation. We also find that the linear degree of polarization of singly Thomson scattered line radiation is wavelength-dependent and hat there are significant differences in the linear degree of polarization from that computed from classical physics in the far red tail. We propose that the semi-forbidden broad emission line C III]1909 may be significantly contributed from Thomson scattering because this line has small resonance scattering optical depth in the broad absorption line region, which leads to distinct and significant polarized flux in this broad emission line.

이 연구는 간호대학생의 대인관계에 대한 어려움과 내재된 갈등 상황을 깊이 있게 이해하는데 그 목적이 있다. 이를 위해 대인관계 갈등을 경험했던 간호학과 학생 12명을 대상으로 2019년 7월부터 9월까지 내러티브 탐구절차를 수행하였다. 본 연구에서 간호 대학생들의 대인관계 갈등은 주로 학업 성적과 관련된 상황이 중심이었으며, 각종 이해 관계가 맞물린 학우들이 대상이었다. 또한 자아 중심의 ‘포커싱적 태도’가 특징으로 드러났다. 이러한 역기능적 대상관계가 중심이 되어 도출된 세부내용은 ‘대인 관계의 중심은 나’, ‘목적적인 관계’, ‘학업성취와 경제적 문제가 우선’, ‘온라인 관계에서 안정감을 느낌’, ‘이질적인 것에 배타적’, ‘남녀 간 경계와 애정문제’, ‘연대감 부족’이었다. 이 연구를 통해 간호대학생들은 새로운 관계맺음을 경험해 볼 수 있는 내러티브 과정을 경험하고, 긍정적 대인관계를 설계할 수 있는 기회를 맞이하였다. 더불어 연구자 또한 그들의 어려움을 이해하고 공감하여 학생들과 한층 가까워지는 경험의 장을 마련하였다. 추후 간호대학 생들에게 특화된 대인관계 중재를 통해 그 효과를 검증할 수 있는 연구가 후속되기를 제언하는 바이다.

Reuse, recycling and recovery (3R) of industrial wastes are common and encouraging in Korea. Industrial symbiosis is one of typical methods for implementing 3R and has been defined as engaging “traditionally separate industries in a collective approach to competitive advantage involving physical exchange of materials, energy, water, and by-products”. The keys to industrial symbiosis are collaboration and the synergistic possibilities offered by geographic proximity. Recently, several countries in East Asia such as Taiwan, South Korea, Japan and China are promoting ‘designed’ symbiosis networks in various industrial complexes based on their national Eco-industrial Park (EIP) demonstration programs. Despite the recently promoted EIP initiatives worldwide, only very few studies furnish the operational and functional details of ‘designed’ industrial symbiosis networks, starting from the planning to implementation stage. The production of terephthalic acid (TPA) in Korea is 6.5 million ton based on 2011. The production of waste generated in the process of TPA is about 15,000 ton/yr and included useful materials like residue TPA as well as isophthalic acid (iPA), benzoic acid (BA) and p-toluic acid (p-TL). Until now, TPA waste was incinerated due to high caloric value. This study was conducted for recovery of valuable materials from industrial waste and utilization of recovered material as an example of Korean EIP. In this study, the experiment was performed to separate above four materials from the waste by solvent (methanol and water) extraction. The solubility of TPA (0.1g/100g) for methanol is relatively low compared to other materials. Also the solubility of BA (68g/L at 95℃) and p-TL (11.6g/L at 98℃) for water is relatively high in comparison with other materials. Finally, BA was separated from p-TL by molecular distillation system. The purity of recovered materials was analyzed by ultra-high performance liquid chromatography (Waters Xevo TQ system). The recovery rate and purity of BA is 90% and 93%. The recovered BA could be recycled the companies which are produced plastic plasticizer and paints.
