최근 스마트폰을 비롯한 다양한 스마트 기기가 확산되면서 미디어 환경 및 이용행태에 변화가 일어나고 있다. 스마트미디어화에 따라 이용자 선택형 서비스가 강화되면서, 인터넷 접속이 가능한 다양한 스마트 기기 내에서의 OTT(Over-The-Top) 서비스 이용이 증가할 것으로 보인다. 지상파, 유료방송 등 전통적인 방송시청 플랫폼에서뿐만 아니라 다수의 플랫폼과 기기를 통한 방송시청이 증가하고 있는 만큼, 이에 대한 이용행태 변화를 분석하는 것이 중요하다. 본고에서는 국내 스마트미디어 이용자의 TV를 비롯한 다양한 스마트 기기 이용행태 조사결과를 분석하여 국내 미디어 시장에 대한 시사점을 도출하고자 한다.

Low temperature scanning laser microscopy (LTSLM) can be used for a two-dimensional display of bolometric response arising from the localized excitation of a sample by the focused laser beam. In this study, the distribution of critical temperature ($T_c$) and critical current density ($J_c$) in YBCO coated conductor were analyzed using LTSLM. For improving the temperature stability, we have modified the system into a double-shielding type. Through the modification, the temperature stability was successfully improved from ${\pm}10mK\;to\;{\pm}2mK$. The superconducting properties of YBCO coated conductors were measured for the sample of a narrow bridge type using wet etching process. The spatial non-uniformity of the ac voltage response, ${\delta}V(x)$, which is proportional to ${\partial}\rho(x,J_B)/{\partial}T$ in the transition temperature region could be observed and displayed in a two-dimensional image.

This document's purposes are to give basic data in the viewpoint of nursing through investigation on the change of teenager's sexual values resulted from pornography experience. 150 middle school boy students who were in first, second and third grade were surveyed. Investigated place is limited only one school which is located in Seoul city. 123 Data was available among the 150 surveyed data. Collected data are statistically processed using SPSS program. To verify the reliability, Cronbach'a was applied and analysed using t- test, ANOVA. In short, the main results of this survey are as follows. 1. The general characteristics of surveyed students: Most of surveyed students were middle school 3rdgrade(42.5%) who had computer at their room ranked first (47.2%). The average using time of internet was more than 2 hours (35.4%, the highest rate). 76.6% of surveyed students answered that they had experience of watching the pornography. 2. 53.1% of surveyed students, which is the highest ratio, experienced pornography before they entered middle school. The curiosity rank first (57.%) about the question why they watch pornography. In case of students who had no experiences of pornography answered that they didn't watch pornography because they had no concern on pornography (51.6%). 3. On sexual values, the average scores of pornography non-experienced (3.77±0.46, full score: 5..0) are higher than those of pornography-experienced (3.53±0.51), showing statically significant difference against pornography -experienced group. 4. Findings of sexual values scores on general characteristics were as follows; The higher in grades, the lower in scores. Top-graded students gained higher scores of sexual values than low graded students showing statistically significant difference in both case of characteristics.
