대중교통전용지구는 교통수요관리와 상권 활성화를 통해 도시의 지속가능성을 제고할 수 있으나 승용차 통행을 제한해 사업을 추진하려는 정부당국과 지역주민 간 갈등이 첨예하여 시행이 어려운 사업이다. 그러나 신촌 연세로 대중 교통전용지구의 경우 사업추진과정과 효과 모두 성공적이라고 평가된다. 그렇다면 연세로 대중교통전용지구의 성공적 도입은 어떻게 설명할 수 있는가? 이와 관련하여 본 연구는 Kingdon(2011)의 다중흐름모형과 Moore(1995)의 정치적 관리를 결합한 분석틀을 활용하였다. 다중흐름모형은 정책이 채택되는 환경적 맥락을, 정치적 관리 전략은 이러한 맥락 속에서 정책을 성공적으로 추진하기 위한 구체적인 실천전략을 제시한다. 분석 결과 연세로의 교통정체와 상권 침체를 해결하기 위해 ‘차 없는 거리’ 등의 대안이 존재했으나 박원순 서울시장이 당선되면서 정책의 창이 열리 고대중교통전용지구라는 정책대안에 대한 논의가 본격화되었다. 서대문구는 개방적 의사결정, 논리적인 협상, 공적 숙의, 공공부문 마케팅 등의 정치적 관리 전략을 통해 지역상인과 유관기관으로부터 정책에 대한 정당성과 지지를 확보하였다. 본 연구는 갈등적인 지역사업을 성공적으로 추진하기 위한 관리적 함의를 제공한다. Transit malls are a means to ensure the sustainability and revitalization of local commercial districts by allowing only public transport and pedestrians to use the roads. Efforts by localities to introduce a transit mall often meet with intense opposition from conflicting interests, which makes it very challenging to put this policy idea successfully into action. The case of Sinchon Yonsei Road, however, is considered an exception: the process in which it was officially designated as a transit mall, as well as the positive outcomes such a decision brought about, makes the case clearly distinguished from other similar attempts. What explains the successful introduction of the Yonsei Road transit mall? To answer this question, the present study took an analytical approach that integrated Kingdon’s(2011) multiple streams framework and Moore’s(1995) political management perspective: the former is instrumental in understanding the context in which policies come to be adopted, while the latter allows assessing the effectiveness of the strategies policy entrepreneurs employ in that process. The analysis shows that the election of Park Won-sun as the Mayor of Seoul opened up the policy window where the idea of converting Yonsei Road into a transit mall began to gain serious attention as a viable policy alternative; it also reveals that Seodaemun-gu - the policy entrepreneur in this case - effectively engaged in a series of policy management strategies, which collectively helped to reach a consensus in a relatively short time span. This successful policy adoption case provides managerial implications for local initiatives that involve a complex array of conflicting interests.

스마트폰 기반의 관광 플랫폼들이 활성화되면서 리뷰 데이터를 활용한 정책 수립 및 서비스 고도화가 다양한 분야에서 이루어지고 있다. 관광 리뷰 데이터를 활용한 선행연구들의 경우 국내 관광객 중심의 연구가 대다수 수행되었으며, 외국인 관광객 연구의 경우 일부 언어로 수집된 데이터와 텍스트 마이닝 기법에 한정하여 연구가 수행되었다. 이에 본 연구에서는 온라인 리뷰 사이트를 통해 '대구 명소' 키워드를 지정하여 외국인들이 작성한 리뷰 데이터 3,515건을 수집하였다. 그리고 LDA 기반의 토픽모델링을 수행하여 관광 토픽을 도출하였으며, 각 토픽별 전역 및 국지적 공간 분석을 수행한 점이 선행연구와 차별성이라 할 수 있다. 분석 결과 전역적 공간 자기상관이 존재하며, 외국인들이 주로 방문하는 관광지들이 국지적으로 결집되어 있음을 확인하였다. 또한 대다수 토픽에서 중구를 중심으로 핫스팟이 도출되었으며, 분석 결과를 바탕으로 지자체 외국인 관광정책 수립 및 토픽모델링 기반의 공간분석 연구의 기초연구로 활용되길 기대하며, 본 연구의 한계점 또한 제시하였다. As smartphone-based tourism platforms have become active, policy establishment and service enhancement using review data are being made in various fields. In the case of the preceding studies using tourism review data, most of the studies centered on domestic tourists were conducted, and in the case of foreign tourist studies, studies were conducted only on data collected in some languages and text mining techniques. In this study, 3,515 review data written by foreigners were collected by designating the "Daegu attractions" keyword through the online review site. And LDA-based topic modeling was performed to derive tourism topics. The spatial approach through global and local spatial autocorrelation analysis for each topic can be said to be different from previous studies. As a result of the analysis, it was confirmed that there is a global spatial autocorrelation, and that tourist destinations mainly visited by foreigners are concentrated locally. In addition, hot spots have been drawn around Jung-gu in most of the topics. Based on the analysis results, it is expected to be used as a basic research for spatial analysis based on local government foreign tourism policy establishment and topic modeling. And The limitations of this study were also presented.

Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.

Zero-Voltage-Switching Three Level Auxiliary Resonant Commutated Pole Inverter for High Power Applications

Jung-Goo Cho,Ju-Won Baek,Dong-Wook Yoo,Chung-Yeun Won 전력전자학회 1995 ICPE(ISPE)논문집 Vol.1995 No.10

A zero voltage switching (ZVS) three level auxiliary resonant commutated pole inverter (ARCPI) is presented for high power GTO inverters. The concept of ACRP for two level inverter is extended to the three level inverter. The proposed auxiliary commutation circuit consists of ?one resonant inductor and two bi-directional switches, which provides ZVS condition to the main devices without increasing device voltage or current stresses. The auxiliary devices operate with zero current switching (ZCS) which enables use of the low cost thyristors. The proposed ARCPI can handle higher voltage and higher power (1-10MVA) comparing to the two level one. Operation and analysis of the ARCPI are illustrated. Experimental results with 10 KW, 4 KHz prototype are presented to verify the principle of operation.

Jung-Min Yon,In-Jeoung Baek,Se-Ra Lee,Wook-Jun Yoo,Sang-Soep Nahm,Yun-Bae Kim,Jai Seup Ro,Bang Yeon Hwang,Soon Sun Kim,Dae Hyun Cho,Beom-Jun Lee,Sang-Yoon Nam,Young Won Yun 한국실험동물학회 2006 Laboratory Animal Research Vol.22 No.1

Licorice, root of the leguminous Glycyrrhiza, is one of the most frequently employed botanicals in foods and traditional medicines. Constituents in licorice are known to have antioxidant, anti-tumor, anti-allergic, antiviral and estrogenic properties. However, there is no report on the effects of licorice on male and female reproductive organs. In this study, to investigate whether licorice affects the antioxidant system of male and female reproductive organs, we analyzed the mRNA expression patterns of superoxide dismutase (SOD) family (types 1 and 2) in the reproductive organs of rats exposed to licorice. Licorice extracts (0.5, 1, and 2 g/㎏ body weight) were treated per oral to male and female rats for 4 and 5 weeks, respectively. Total RNAs were extracted from male reproductive tissues (testes, epididymides, prostates, and seminal vesicles) and female reproductive tissues (ovaries, uteri), and then RT-PCR was performed with the specific primers of each SOD gene. SOD1 mRNA was weakly increased by 0.5 and 1 g/㎏ of licorice in testes, and increased by 0.5, 1, and 2 g/㎏ in epididymides. It was increased in prostates and was irregularly increased in seminal vesicles at all doses tested. SOD2 mRNA was weakly increased in testes at all doses tested. It was weakly decreased by 0.5 g/㎏, and was increased by 1 g/㎏ of licorice in epididymides, but greatly decreased by treatment of 2 g/㎏ of licorice in prostates. It was increased by 1 g/㎏ of licorice, but greatly decreased by 2 g/㎏ of licorice in seminal vesicles. SOD1 mRNA was weakly increased in ovaries at all doses tested, and was weakly increased by 2 g/㎏ of licorice in uteri. SOD2 mRNA was not changed in ovaries, but was slightly decreased in uteri at all doses tested. These findings indicate that licorice may influenced the antioxidant system of male and female reproductive organs, although further study is necessary.

Jung-Kyu Park,Sung-Hak Cho,Jae-yong Yu,Jae-Gu Kim,Koji Sugioka,Jong-Wook Hong,Won-Ha Heo,Kyung-Hyun Hwang 한국레이저가공학회 2011 한국레이저가공학회지 Vol.14 No.1

Photo-induced gratings in flexible PDMS (polydimethly siloxane) film are directly written by a high-intensity femtosecond (130fs) Ti: Sapphire laser (λp = 800nm). The refractive index modifications with 4 μm diameters were photo-induced after the femtosecond irradiation with peak intensities of more than 1 × 1011W/cm2. The graded refractive index profile was fabricated to be a symmetric around the center of the point at which femtosecond laser by controlling both laser power and focused depth. The change on refractive index in the laser-modified regions was estimated to be approximately 10-3. The internal flexible symmetric diffraction gratings in PDMS film was successfully fabricated using a femtosecond laser.

Expression Analysis of Galectin-1 from Fat in Berkshire Pigs

Jung, Won Yong,Cho, Eun Seok,Kwon, Eun Jung,Park, Da Hye,Chung, Ki Hwa,Kim, Chul Wook Asian Australasian Association of Animal Productio 2008 Animal Bioscience Vol.21 No.2

Galectins are a group of animal lectins consisting of galectin-type carbohydrate recognition domains (CRD) with relatively minor domains. The biological properties of galectins include the regulation of inflammation, intercellular adhesion, cell differentiation and cell death. The diverse kinds of galectin suggest variety in their biological roles. Galectin-1 is released during adipocyte differentiation and is associated with fat which is one of the important factors for meat quality. To verify expression level, a 0.5 kb clone of galectin-1 was obtained from cDNA prepared from back fat tissue of a Sancheong Berkshire pig with good quality meat, and the galectin-1 gene identified. The deduced amino acid sequence of the galectin-1 gene was compared with those obtained from other species. By using RT-PCR and Real time-PCR, an attempt was made to determine the expression level of galectin-1 and to compare with various tissues (tenderloin and back fat) taken from pigs in different groups. Grouping of pigs was based on growth-stage (weighing 60, 80, and 110 kg) and the sub-speciation (Yorkshire and Sancheong Berkshire pigs). We attempted to determine influences of pig species, growth stages and tissue variations on the expression level of the galectin-l gene and it was revealed that the expression pattern of the galectin-1 gene was significantly different (p<0.01 or p<0.05). Galectin-1 genes were expressed more highly in the back fat tissues of pigs weighing 110 kg than in those weighing 60 kg or 80 kg. However, the lowest expression was seen in the tenderloin tissues of pigs weighing 110 kg. Sancheong Berkshire pigs showed higher expression of the galectin-1 gene compared to Yorkshire pigs. Accordingly, it is considered that the expression pattern of the galectin-1 gene influences the growth of back fat tissues and the pig speciation relationship. Previous studies suggested that different expression of galectin-1 genes represents variety among the breeds and is closely related to fat tissue growth, conjugation and catabolism. Further, this study suggests that the expression of galectin-1 at a specific growth stage and tissue contributes significantly to the overall meat quality of Sancheong Berkshire pigs.

A Research on the Evacuation speed of foreign students Dormitory Building through Full-Scale Experimental

Wook-Jung Na,Byeung-Hun Son,Won-Hwa Hong 중소기업융합학회 2015 중소기업융합학회 국제학술대회논문집 Vol.2 No.1

Recently many foreign students are currently studying in Korean University and Most of these students live in foreigner dormitories. The dormitory buildings have a relatively high risk of fire and evacuation safety by compare to other buildings. As well as foreign students because of cultural differences and lack of language skills can be put to greater difficulties in emergency. This study analyzes the evacuation performances of dormitory buildings through Full-scale evacuation experimental. Total evacuation average speed is similar to the average walking speed(1.3m/s) in the adult fast step. There is no difference in the evacuation speed, depending on the country and the gender. The experimental results provide basic data for improving the safety of the evacuation of foreign dorm.
