This study aims at analyzing the research trend in Electricity, Electronics, and Communication Subject since 1973, which is the beginning year in research in Electricity, Electronics, and Communication Subjects, up to the present year of 2010. We also try to provide explicit directions and suggestions for future researches. A total of 98 studies, including master's and doctoral theses, were collected through RISS(Research Information Sharing Service), KISS(Koreanstudies Information Service System), and DBPIA(special database for domestic research information). Three researchers reviewed them using analytic method. The results were as follows. Of the researches analyzed, 2 studies(2.04%) were in 1970's. The researches in Electricity, Electronics, and Communication Subjects were not actively performed until 1996. Since then, 92.86% of total studies have been done so far and the number of research activities in these subjects are shown to be continuously growing. 50 studies were related with Curriculum and instruction area. Design/Development of Instruction Material area was the most popular topic, and Education Assessment area the least. Research design was mainly descriptive, and studies in academic journals were more than the dissertations. Research mostly focused on the students and the teachers as subjects. University was the main research agency where studies were carried out.

많은 소비자들이 가치지향적인 의사결정을 할 때 제품의 품질을 매우 중요한 요소로 생각하며, 제품구매시 불완전한 정보 상황에서 빈번히 제품품질의 지표로서 가격을 이용한다고 한다(Peterson & Wilson. 1985). 이와 관련하여 시장에서의 실제 가격과 객관적 품질과의 관계를 분석하여 소비자의 효율성을 파악한 연구가 각국에서 이루어져 왔으나, 패션제품에 관한 가격과 객관적 품질과의 관계에 관한 연구는 국내 외적으로 매우 미흡한 실정이다. 따라서 본 연구의 목적은 1990년대 한국과 미국 패션시장의 가격과 객관적 품질간의 상관관계를 비교 분석함으로써 양국 패션제품의 품질수준을 비교해 보 는데 있다. 본 연구의 결과를 통해 가격이 제품품질의 지표가 될 수 있는가를 파악할 수 있을 것이다. 이를 위해 본 연구에서는 다음과 같은 연구문제를 설정하였다. 첫째, 한국과 미국 패션제품 시장의 가격과 품질의 상관관계는 전체적으로 어떠한 차이가 있는가\ulcorner 둘째, 한국과 미국 패션제품의 가격과 객관 적 품질의 상관관계가 패션산업범주에 따라 어떠한 차이가 있는가\ulcorner 마지막으로, 본 연구의 결과와 같은 제품의 품질에 대한 정보탐색으로부터 얻을 수 있는 한국과 미국 소비자의 구매이득은 어느 정도인가\ulcorner 본 연구를 위한 내용분석에 이용된 자료는 양국의 소비자의 권익보호를 위한 중립적 정보원에서 발간하고 있는, 한국의 <소비자 시대>와 미국의 에 개 재 된 1990년부터 1999년까지 의 상품비교테스트 정보중에서 패션제품군에 관련된 자료를 토대로 하였다. 수집된 자료는 한국의 36개 패션제품군, 470개 제품과, 미국의 40개 패션제품군. 692개의 패션 제품이었으며, 패션산업범주는 여성복, 남성복, 유니 섹스 의류, 스포츠 의류, 유.아동복, 언더웨어. 잡화. 제화류, 침장류, 섬유직물, 화장품. 학생복 등 11 가지 산업범주로 분류하였다. 본 연구의 결과를 요약하면 다음과 같다. 첫째, 한국과 미국 패션제품의 지난 십년간의 가격 과 품질의 상관관계는 매우 약한 정(+)의 상관을 가지고 있었다. 한국패션제품의 전체 서열상관계수의 평균은 0.091이었고, 미국의 상관계수 평균은 0.192였 다. 상관계수의 수치만으로 볼 때 한국보다는 미국 패션제품의 가격과 품질간의 상관관계가 조금 높게 나타났으나, 양국간 통계적인 차이는 없었다. 또한, 한국 패션제품의 경우에는 제품군의 가격대별 상관관계를 살펴보았는데, 그 결과 1만원 미만의 저가 제품군과 330만원이상의 고가의 제품군의 경우 부(-)의 상관계수를 나타냈다. 둘째. 1990년대 한국과 미국 패션시장의 가격과 품질간의 상관계수의 범위는 제품군별. 산업범주별 로 상이한 분포를 보이고 있었다. 패션제품군별로 보 면, 한국의 경우는 가장 높은 '여행용가방(r = 0.707)' 에서 가장 낮은 '자외선 차단화장품(r = -0.58)'까지, 그리고 미국 패션제품군의 상관계수의 범위는 '팬티 스타킹'의 0.820에서 '남성용 런닝슈즈'의 -0.472까지의 분포를 나타냈다. 마지막으로, 제품의 가격과 품질에 대한 정보를 소비자가 알 경우 얻을 수 있는 소비자의 구매이득 을 추산한 결과 패션제품시장에서 완전한 품질정보를 가지고 있다고 가정한 '현명한 사람'은, 최고가격의 제품만을 구입한다고 가정한 '부유한 사람들'의 구입방식에 비해 최고 좋은 품질의 상품을 총 지불액의 비율로 보아, 한국의 소비자는 약 50% 정도를, 미국의 소비자는 약 91%나 되는 액수를 절약하여 구매할 수 있는 것으로 나타났다. 이상의 본 연구의 결과를 종합하여 볼 때 한국과 미국 모두 제품군별, 그리고 산업범주별로 상관관계가 차이를 보이고 있어, 양국의 소비자들이 패션제품 의 품질을 평가함에 있어 오로지 가격에 대한 정보만을 이용하는 것은 위험하고 비합리적인 구매의사 결정이라고 볼 수 있다. 따라서 소비자가 좀 더 합리적인 구매의사결정을 하여 재정적 손실을 막기 위해서는 가격과 품질에 관한 신뢰있는 정보의 탐색이 반드시 필요하다고 본다.

Incident duration prediction is one of the most important steps of the overall incident management process. An accurate and reliable estimate of the incident duration can be the main difference between an effective incident management operation and an unacceptable one since, without the knowledge of such time durations, traffic impact can not be estimated or calculated. This research presents several multiple linear regression models for incident duration prediction using data consisting of 384 incident cases. The main source of various incident cases was the Traffic Incident Reports filled out by the Motorist Assistant Units of the Korea Highway Corporation. The models were proposed separately according to the time of day(daytime vs. nighttime) and the fatality/injury incurred (fatality/injury vs. property damage only). Two models using an integrated dataset, one with an intercept and the other without it, were also calibrated and proposed for the generality of model application. Some findings are as follows ; ?Variables such as vehicle turnover, load spills, the number of heavy vehicles involved and the number of blocked lanes were found to significantly affect incident duration times. ?Models, however, tend to overestimate the duration times when a dummy variable, load spill, is used. It was simply because several of load spill incidents had excessively long clearance times. The precision was improved when load spills were further categorized into "small spills" and "large spills" based on the size of vehicles involved. ?Variables such as the number of vehicles involved and the number of blocked lanes found not significant when a regression model was calibrated with an intercept. whereas excluding the intercept from the model structure signifies those variables in a statistical sense.

With acquisition of satellite image being facilitated due to recent advancement in Electro optical and astronautic technologies, focus on establishment of Geoinformation and analysis using satellite images have increased. This research have conducted digital plotting and digitizing operation, utilizing stereo images and grey level images provided by SPOT5 satellite and evaluated the accuracy through comparison and analysis with digital map results. Digital plotting results acquired using stereo images have been compared and analyzed on the basis of scale 1:25,000 digital map results published by National Geographic Information Institute. Accuracy of 20 check points have showed RMSE results 5.369 m at X (Easting) and 4.718 m, digitizing using grey level images showed RMSE results 7.616 m in X (Easting) and Y (Northing) 6.532 m. This is within the allowance of accuracy standards for scale 1:25,000 maps, and although digitizing operation was confirmed to have lower accuracy than that of digital plotting, using the former is considered to be more effective in terms of economical efficiency.

This study was conducted to analyze the trend of quantitative research regarding female North Korean refugees in order to broaden our understanding of North Korean women and provide directions for future research. In August 2017, the Korean studies Information Service System (KISS) and Nuri Media (DBpia) databases were used to search academic peer reviewed journal articles with the following keywords: "North Korean female", "North Korean female refugees" and "North Korean female defectors". Trend analysis included a content analysis of the study finding section, along with analysis of the general characteristics of the study such as published journals, year of publication, study methodologies, and subject of the study. The main findings are as follows: First, Korean Journal of Woman Psychology was the journal with the most studies on female North Korean refugees. Second, as a result of looking at research trends by year, there was only one study on North Korean female refugees published between 2000 and 2004, and the number started to increase in 2010(8 articles, 22.22%). Third, according to the analysis of research trends by research methods, survey method was most frequently used. Fourth, statistical analysis was most often utilized analysis methodology(34 studies, 94.44%). Fifth, in the content analysis, North Korean female refugees' mental health and emotional issues(17 studies, 47.22%) were the most often the focus of studies being analyzed, followed by social adjustment issues((5 studies, 13.89%). Based on these results, directions for future studies were suggested.

This study examined the effect size of virtual reality programs on the upper extremity function of stroke patients through a meta-analysis. Databases, such as the Research Information Sharing Service, the Korean Studies Information Service System, the National Library of Korea, the Korean Citation Index, and the National Digital Science Library, were used. Previous articles were surveyed for virtual reality programs between January 2010 and June 2019. A meta-analysis was performed by selecting the final 14 studies based on the PICO standard. The RoB and RoBANS tools were used as quality assessment tools for randomized and non-randomized control trials, respectively. The CMA 3.0 program was used to calculate the effect size of each study. Sub-group analysis, meta-regression analysis, and publication bias were performed. The total effect size of the virtual reality programs on the upper extremity function was Hedges's g=0.390 (95% CI: 0.192~0.587) (p<.05). The virtual reality program positively affects the upper extremity function of stroke patients. Therefore, the development of various virtual reality programs and industry-academia cooperation technology for stroke patients is required in accordance with the fourth industry. Randomized control trials and detailed upper extremity function studies for virtual reality programs will be needed in follow-up studies.

Recently, there happens many purchasing cases encouraged by friends' recommendation in SNS (Social Network Service). This study investigates the effect of friend recommendation on consumers' purchasing heuristic. For this purpose, we compare the effect of friend recommendation with consumer recommendation in terms of trustworthy, specialty, relevancy. Usually, the frequency of friend recommendation is far lower than that of consumer recommendation. Hence, we examine how the effect of information source (friend recommendation or consumer recommendation) is moderated by the frequency of recommendation, as well. As results, this study finds out that, under the same frequency, friend recommendation does not have significantly stronger effect on the purchasing heuristic, although friend recommendation is evidenced as one of significant heuristic inducers. However, in terms of trustworthy, friend recommendation is significantly superior to the consumer recommendation. Moreover, under sufficiently higher frequency, friend recommendation works as better heuristic factor than consumer recommendation. The results deliver managerial implications in the perspective of understanding consumers' purchasing decisions and responding strategies of firms.

There emerges a growing concern about South Korea's intellectual dependence on U.S. financial news media. However, those media's inherent relationship with national economic and financial interests has been poorly addressed. This paper thus attempts to identify such a strategic partnership between media and the government by analysing news coverages over four critical arena interwoven with U.S. dollar based financial system. For this purpose, total 152 news articles about Asia crisis, Asian Monetary Fund, Malaysia currency crisis and the new international financial architecture have been examined in terms of frame, attitude, cue-givers and discursive strategies. Research results indicate that not only have the media actively deferred to government leadership bur they have also acted as public diplomats in way of not hampering journalistic credibility. Hence, it is claimed that Korean society needs to formulate a model of media's strategic partnership with government at least in foreign policy arena, as well as to launch discursive strategies against nation-bound global news media.

The purpose of this review was to evaluate the effects of simulation-based education on clinical competence and confidence in nursing students and summarize the available evidence on the simulation-based intervention. A systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses: the PRISMA Statement was conducted. Studies published between 2005 and 2014 were reviewed using the following databases: RISS, KISS, and Google Scholar. The keywords used were nursing and either simulation or simulator. Selected studies were assessed for methodological quality using Quality Assessment Tool for Quantitative Studies. Seventeen studies were identified, including a total of 1,912 nursing students. All the 16 studies found simulation as a valid strategy on clinical competence and confidence in nursing education. This review provides updated evidence for simulation-based learning in nursing education. Further studies are needed to increase generalizability using randomized controlled trials, enough sample size, and longitudinal study design. In addition, valid measurements are needed to assess the main outcomes.
