참관기 / "2003년 E3에서 한국 높아진 위상 실감했다"
서정원,Seo, Jeong-Won 한국데이터베이스진흥원 2003 디지털콘텐츠 Vol.6 No.-
지난 5월 13일부터 16일까지 LA에서 E3가 개최됐다. E3(Electronic Entertainment Expo)는 미국 IDSA(Interactive Digital Software Assosiation) 협회가 매년 LA에서 개최하는 E3는 세계에서 가장 큰 인터렉티브 게임업계의 트레이드 쇼이다. 미국 게임사들에게 가장 중요한 마케팅 이벤트인 E3에서는 게임사들 대부분이 주요 발표를 하며 이곳에서 발표된 게임들의 87%가 게임매출의 반이상을 차지하는 크리스마스, 연말연시를 겨냥해 출시된다.
Characteistics of Charge Traps and Poling Behavior of Poly (Vinylidene Fluoride)
서정원,류균상,이호성,Seo Jeong Won,Ryoo Kun Sang,Lee Hoo Sung Korean Chemical Society 1985 Bulletin of the Korean Chemical Society Vol.6 No.4
Transient charging and discharging currents as well as space charge limited currents have been measured in biaxially stretched poly(vinylidene fluoride) film under various poling fields and temperatures. At low temperatures and short poling times, the I-V characteristics showed shallow trap behavior. When the current values extrapolated to the infinite time, the I-V characteristics indicate that the distribution of the trap energy levels is uniform or very broad. The abnormal suppression of current at higher poling voltages and the high discharge rate observed also in the same voltage range are attributed to the morphological changes due to dipole reorientation.

In this study, the procedures for the preliminary design of the turbo-shaft engine for the light multi-purpose helicopter are established. The engine specifications are determined through the performance analysis on the on-design and off-design conditions by the use of simulation program. In addition, the effect of humidity on the engine performance is examined by considering the change of the gas properties and characteristic maps due to moisture contents. The calculation results show that the engine power is reduced by the existence of moisture in working fluid.
정신과병동 간호사의 소진 영향 요인에 관한 연구 -폭력경험, 폭력대처, 사회적지지-

본 연구는 폭력경험으로 인한 정신과병동 간호사의 소진을 감소시키고 문제 중심의 표준화된 폭력대처 중재방안을 수립하기 위해 폭력경험, 폭력대처, 사회적지지가 소진에 미치는 영향요인을 파악하기 위한 서술적 조사연구이다.연구 대상자는 정신과 병원에서 근무하는 임상경력 1년 이상인 병동 간호사 204명이었다. 자료수집기간은 2018년 7월 1일부터 8월 31일까지 구조화된 설문지로 시행하였다. 수집된 자료는 SPSS program을 이용하여 평균, 표준편차, t-test, ANOVA, Pearson’s Correlation coefficient, Multiple Regression으로 분석하였다. 연구결과는 다음과 같았다. 정신과병동 간호사는 언어적 폭력 92.2%, 신체적 위협 92.2%, 신체적 폭력 75.5%를 경험하고 있었다. 대상자의 폭력경험과 폭력대처(r=0.15. p <.027), 폭력경험과 소진(r=0.16, p <.017)은 정적 상관관계, 폭력대처와 사회적지지(r=0.30, p <.001)는 정적 상관관계, 사회적지지와 소진(r=-0.28, p <.001)은 부적 상관관계를 나타냈다. 또한 소진에 영향을 미치는 요인으로 간호직 만족도, 사회적지지, 신체적 폭력경험이 나타났다. 소진을 설명하는 회귀모형은 약 33.3%의 설명력을 나타내었다. 그러므로 정신과병동 간호사의 폭력경험을 낮출 수 있는 예방교육과 사회적지지 강화를 위한 체계마련 및 간호직 만족도를 향상시키는 환경을 조성한다면 소진을 감소시켜 양질의 간호를 제공할 수 있으리라 생각된다. This study is descriptive survey research to find out factors which violence experience, violence coping and social support affect. This study aims at reducing burnout of psychiatry nurses and founding problem-oriented violence handling standardized intervention. The subjects were 204 nurses who have worked for more than a year in a hospital. The data collection period was conducted with structured survey from July 1, 2018 to August 31, 2018. Collected data was analysed with average, standard deviation, t-test, ANOVA, Pearson’s Correlation confident, Multiple Regression and this data will go to by SPSS. The results of the study were as follows. 92.2% of psychiatry nurses are experiencing verbal violence, 92.2% are experiencing physical threat and 75.5% are experiencing physical violence. Relations between violence experience and violence coping(r=0.15. p <.027), violence experience and burnout(r=0.16, p <.017) were positive correlation. Relation between violence coping and social support(r=0.30, p <.001) was positive correlation, and social support and burnout(r=-0.28, p <.001) was negative correlated. Also we found out that nursing job satisfaction, social support and physical violence experience affect burnout. Which shows model’s explanatory power was 33.3%. Therefore preventive discipline which can reduce violence experience of psychiatry nurses, founding systems to reinforce social support and creating circumstance where nursing job satisfaction can increase will help reduce burnout and serve better nursing.

The Makgeolli industry had expanded rapidly since the late 2008 in response to significant increase of exports as well as various government supports. However, the expansion of Makgeolli industry has slowed down in recent years due to the various reasons. It is essential for Makgeolli industry to correctly examine consumer purchasing behavior in order to restore its increasing market share in the alcohol market. This study classified Makgeolli consumers based on the patterns of lifestyle and analyzed purchasing behavior using survey data. Empirical results showed that the perceptions, places to drink, choice attributes of Makgeolli are statistically significantly different depending on the lifestyle of consumers. The findings of this study would provide empirical basis to develop proper market segmentation strategies in the Makgeolli industry to expand its market.
