본 연구는 영상콘텐츠 산업과 과학문화 산업의 지형 변화에서 시작되었다. 모바일 과학기술 영상 콘텐츠는 수요와 정책적 지원에 따라 성장 가능성이 예견된다. 본 연구의 목적은 과학기술 관련 모바일 영상콘텐츠 활성화를 위해 현황을 분석하여 기획 및 제작시의 시사점을 제시하는 것이다. 따라서 본 논문은 모바일 영상 중 영향력이 가장 큰 유튜브의 과학기술 채널의 영상을 사례로 하여 유형 및 스토리텔링 분석을 시도하는 융복합적 연구를 진행하였다. 연구결과 및 내용은 다음과 같다. 첫째, 과학기술 유튜브 채널 글로벌 선도그룹의 영상 콘텐츠는 과학기술의 맥락과 활동에 따라 활동형, 해설형, 비평형의 세 유형으로 범주화된다. 둘째, 언어의존성이 낮고 재매개 가능성이 높은 활동형 채널은 다시 라이프 해킹형, 소품 제작형, 파괴형, 탐구형으로 분류된다. 셋째, 활동형 채널들의 핵심 스토리텔링 전략은 일상적 소재를 전문과학기술적 방법을 통해 다루는 익숙함과 낯섦의 조화이다. 이러한 연구결과를 바탕으로 국제적 경쟁력을 가질 수 있는 킬러 콘텐츠 기획 및 제작을 기대한다.

The purpose of this study is to investigate the differences in consumer clothing shopping orientation and shopping behaviors by the multi-selection of internet and offline stores. The data were collected from 201 men and women in their twenties and the respondents were grouped into three as internet-store users, multi-store users, and offline-store users. The data were analyzed using factor analysis, ANOVA, post-hoc analysis, frequency analysis, and chi-square analysis. The results are as following. First, the clothing shopping orientation was partly different among the groups. Regarding the offline shopping orientation, the groups showed difference in the impulsive orientation, and regarding the online shopping orientation, the groups showed differences in the goal oriented and enjoying orientation. In all the three cases, the internet users showed strongest orientation, and the next were multi-store users and offline-store users. The cause of these results were explained as the familiarity and experience with the channel. Second, the clothing shopping behaviors were also partly different among the groups. The groups showed no differences in the preferred store type and benefits sought, but showed significant difference in the attitude toward the internet shopping. The internet-store users showed most positive attitude, and the next were multi-store users and offline-store users.

The purpose of this study was to investigate the spatiotemporal cortical activation pattern and functional connectivity during visual perception of words. 61 channel recordings of electroencephalogram were obtained from 15 subjects while they were judging the meaning of Korean, English, and Chinese words with concrete meanings. We examined event-related potentials (ERP) and applied independent component analysis (ICA) to find and separate simultaneously activated neural sources. Spectral analysis was also performed to investigate the gamma-band activity (GBA, 30-50 Hz) which is known to reflect feature binding. Five significant ERP components were identified and left hemispheric dominance was observed for most sites. Meaningful differences of amplitudes and latencies among languages were observed. It seemed that familiarity with each language and orthographic characteristics affected the characteristics of ERP components. ICA helped confirm several prominent sources corresponding to some ERP components. The results of spectral and time-frequency analyses showed distinct GBAs at prefrontal, frontal, and temporal sites. The GBAs at prefrontal and temporal sites were significantly correlated with the LPC amplitude and response time. The differences in spatiotemporal patterns of GBA among languages were not prominent compared to the inter-individual differences. The gamma-band coherence revealed short-range connectivity within frontal region and long-range connectivity between frontal, posterior, and temporal sites.

유통업체는 다양한 상품구색을 갖는 것이 좋다는 생각이 일반적이다. 그리나 최근 연구들은 선택대안의 수를 증가시키는 것이 오히려 소비자 선택을 떨어뜨린다고 한다. 본 연구는 선택대안의 수가 늘어나는 맥락에서 소비자 구매결정에 영향을 미치는 요인을 파악하는 데 목적이 있다. 연구 결과, 본 연구에서는 선택대안의 수가 실제 고려제품군의 크기에 해당하는 $3{\sim}9$개인 경우, 선택대안의 수가 늘어남에 따라 비선택 비율이 줄어드는 것(선택 비율이 증가하는 것)을 알 수 있었다. 특히 선택대안의 수가 선택여부에 미치는 영향은 지배적 대안이 없을 때보다는 있을 때 더 높게 나타났다. 그리고 대안의 수와 함께 소비자의 제품에 대한 친숙도가 선택여부에 어느 정도 영향을 미치는 것으로 나타났다. 지배적 대안이 있을 경우에는 친숙도가 선택여부에 영향을 미치지 않았으나, 지배적 대안이 있을 경우에는 소비자의 제품에 대한 친숙도는 자체적으로는 선택여부에 영향을 미치지 않고, 대안의 수와 상호작용을 통해 선택여부에 영향를 미치는 것으로 나타났다. 마지막으로 이러한 결과를 바탕으로 실무적 시사점과 연구의 한계점에 대해 논의하였다.

The analysis performed here is aimed to increase the familiarity of hydrologic process especially for the small basins which are densely gaged. Kyung An and Mu Shim river basins are selected as a representative basin according to the criteria which UNESCO has established back in 1964 and being operated under the auspice of Ministry of Construction. The data exerted from these basins is utilized for the determination of characteristics of procipitation and runoff phenomena for the small basin, which is considered as a typical Korean samall watershed. The study found that the areal distribution of preciptation did not show any significant deviation from the point rainfall. Since the area studied is less than 20 km#, the pointrainfall may be safely utilized as a representative value for the area. Also the effect of elevation on the precipitation has a minor significance in the small area where the elevation difference is less than 200m. The methodology developed by Soil Conservation Service for determination of runoff value from precipitation is applied to find the suitability of the method to Korean river basin. The soil cover complex number or runoff curve number was determined by comsidering the type of soil, soil cover, land use and other factors such as antecedent moisture content. The average values of CN for Kyung An and Mushim river basins were found to be 63.9 and 63.1 respectively under AMC II, however, values obtained from soil cover complex were less than those from total precipitation and effective precipitation about 10-30%. It may be worth to note that an attention has to be paid in application of SCS method to Korean river basin by adjusting 10-30% increase to the value obtained from soil cover complex. Finally, the design flood hydrograph was consturcted by employing unit hydrograph technique to the dimensionless mass curve. Also a stepwise multiple regression was performed to find the relationship between runoff and API, evapotranspiration rate, 5 days antecedentprecipitation and daily temperature.
