소셜벤처는 창의성과 혁신성을 가지고 영업활동을 통한 수익을 기반으로 취약계층에게 사회서비스를 제공하거나 취약계층 대상의 일자리를 제공하는 등 국민의 삶의 질을 높이는 사회적 목적을 추구하는 진취적인 사회적기업 모델로서 사회적기업의 발전을 위한 그 원동력으로 작용될 가능성이 높다. 최근 창의적 비즈니스 아이디어로 사회문제를 해결하려는 소셜벤처와 같이 사회적기업에 대한 청년들 의 관심이 증가되고 소셜벤처와 관련되어 일자리가 확산되는 등 혁신적인 모델을 통한 사회적기업의 사 회적 역할과 기능이 확대될 것으로 기대되고 있는 추세이며, 사회적기업과 관련된 공공기관들에서도 이 같은 추세에 따라 각종 다양한 정책들을 제시하고 있는 실정이다. 이러한 흐름에 따라 본 연구에서는 혁 신적인 아이디어와 창의성을 가진 소셜벤처에 대한 체계적인 지원을 통하여 혁신적인 사회적기업 모델로진화하여 보다 진보된 사회서비스의 제공과 청년실업 해소에 기여할 수 있는 소셜벤처의 지원정책에 대 한 분석을 통해 소셜벤처의 특수성에 적합한 실천적인 전략을 제시하고자 하는데 연구의 목적을 두었다. 현재 진행되고 있는 소셜벤처 지원현황과 문제점에 대한 분석을 통하여 소셜벤처의 특수성에 적합한 소 셜벤처를 활성화하기 위한 정책적인 방향성에 대한 방안을 제시하였다.
An in-vivo diagnosis of trace Mg(II) ion was performed using a low-cost and environment-friendly voltammetric method, using a graphite counter and reference electrodes and a fluorine-immobilized graphite working electrode, and clean deep seawater was used as an electrolyte solution. Under optimum conditions, the analytical working ranges attained microgram ranges, and a detection limit of 80.6ugL-1 was obtained using stripping voltammety with 60 sec accumulation time. Ex-vivo application was performed on fish liver and mice droppings. The developed techniques can be applicable to tumor cell analysis.
This study was conducted to investigate the effects of bacterial inoculation (Lactobacillus plantarum) and cutting height on the chemical composition, fermentation characteristics and in vitro dry matter digestibility (IVDMD) in whole crop barley silage. Barley forage (Youngyang hybrid) was harvested at about 27% of dry matter (DM) level at two different cutting height (5 vs. 15 cm). And it was chopped to 5 cm length and treated with or without L. plantarum. Four replicates of each treatment were ensiled into 10 L mini silo (3 kg) for 100 days. After 100 days, bacterial inoculation decreased (p=0.001) DM content, while increased cutting height increased (p=0.002) DM in uninoculated silage. Crude protein (CP) concentration was decreased by increasing height in uninoculated silage (8.84 vs. 8.16) but increased in inoculated silage (8.19 vs. 8.99). Both neutral detergent fiber (NDF) (p<0.011) and acid detergent fiber (ADF) (p<0.004) were decreased by increasing cutting height of forage at harvest. The IVDMD and ammonia-N was increased (p=0.001) by increasing cutting height and inoculation, respectively. Lactic acid bacteria (LAB) was increased (p=0.002) in inoculated silage, but yeast count was decreased (p=0.026) in uninoculated silages. It is concluded that increased cutting height of forage at harvest could be useful to make a fibrous portion with increase of dry matter digestibility of silages.
코르티코트로핀분비인자(Corticotropin-releasing factor)는 스트레스 반응에 관여하는 호르몬으로, 최근 스트레스가 탈모와 같은 피부질환에 영향을 미친다는 보고들이 많아지고 있다. 보고에 따르면, 사람 모낭 배양에서 코르티코트로핀분비인자는 길이생장을 억제하며, 모낭의 조기퇴행을 유도하고 모기질각질형성세포(hair matrix keratinocyte)의 세포사멸을 촉진시킨다. 본 연구에서는 코르티코트로핀분비인자가 모발성장과 모주기조절에 핵심적으로 역할하는 모유두세포에 미치는 영향에 대해 알아보고자 했다. 시상하부-뇌하수체-부신축의 주요 스트레스호르몬들인 코르티코트로핀분비인자, 부신피질자극호르몬, 그리고 코르티솔을 사람 모유두세포에 처리하였다. 흥미롭게도, 코르티코트로핀분비인자가 모발성장과 관련된 사이토카인(KGF, Wnt5a, TGFβ-2, Nexin)의 발현을 변화시키는 것을 관찰하였으며, 세포 내 cAMP의 수준을 증가시켰고, 수용체의 발현을 억제시켰다. 이러한 변화는 수용체의 길항제인 antalarmin과 astressin2B, 또는 PKA 억제제의 전처리로 인해 막을 수 있었다. 코르티코트로핀분비인자는 cAMP/PKA경로를 통해 POMC의 발현을 유도하는데, 사람 모유두세포에서도 이 호르몬의 처리가 POMC mRNA의 발현을 증가시키는 것을 확인할 수 있었으나 부신피질자극호르몬의 변화는 western blot으로는 확인할 수 없었다. 이러한 결과들을 바탕으로, 코르티코트로핀분비인자가 그 수용체를 통해 사람 모유두세포 내 모발성장 관련 사이토카인의 발현을 조절함을 확인하였으며, 이는 코르티코트로핀분비인자의 수용체 길항제가 스트레스성 탈모환자를 위한 치료제 혹은 화장품 소재로써 활용될 수 있음을 보여준다.
Since Rigollet first discovered a comet in 1939, many follow-up observations have been made, particularly in Europe. It is now known that the Rigollet comet is identical with the one observed by Herschel in 1788, and thus it is now called 35P/1939 O1 or the Herschel-Rigollet comet. Yumi, a Japanese astronomer, also observed the Rigollet comet in Korea using a 6-inch refractor telescope, and published his data in two Japanese journals (Bulletin of the Observatory of the Government-General of Korea and Publication of the Lecture on Meteorology). In his paper, Yumi also referred to observations by Hirose and Kanda in Japan. However, their works have not been given attention by international society. In this study, we analyze the observation data of Yumi and present preliminary orbital elements using it with a modified Gauss method. We expect that this study will be used to refine the orbital elements of the Rigollet comet by orbital-calculation experts. For that reason, we have also transcribed all the observational data presented by Yumi.
The purpose of this study is to find out the color prefernece on rural rooftop color. Today, public profit value of a rural community has been heavily recognized in the areas of preservatoin of pro-environmental and traditional life styles and foundation of collective community. Comparatively with urban, rural town conserves the scenic of those days when the historic landscape existed. Therefore, elements of historic and tradition in rural town are interesting resources to people who want traditional experience. Color is one of themost influenced elements for the image of Landscape. On the other hand, radical modernization has brought conflicting color element that does not blend with existing environmental color. Among others, roof represents on of the important traits of rapidly developing rural community due to vast amount of space it covers. In order to come up with more appropirate coloring scheme, it is necessary determine color that forms a balance with present conditions of rural life and historic landscape. This study provides more objective rooftop coloring selection process by employing additional surveys regarding color image adjective. I justified necessity of the balance between environmental color and roof color through analyzing correlation between environmental color of the rural town and Color Image Scale of the preliminary selection of roofs.
Pro-environmental life styles, foundations of a collective civilization and preservation of our tradition at rural communities hold a great public profit value, of which importance has been strongly emphasized during last decade. Here, the environmental color is one of the most influential elements that determine the image of the rural landscape. Whenever an alternative color element is introduced to rural town, it is very important to examine its effect on the existing environmental color. Typically, a preference-surveying method has been used to evaluate the suitability of such environmental color balance. However, we note that the reliability of this method is limited by the subjectivity of a respondent. And thus, it is highly desirable to develop a more objective method. We propose a feasibility study for using an aesthetic-measure to evaluate the environmental color of a rural town. In this work, we looked into the validity of our approach by comparing its result with that of the preference-based-method as a way to determine the environmental color. Our study is based on 20 photo images from Ansung-city Yangsung-myeon Donghang 2ri Kyo-dong town in Kyongki Province.
