The usefulness of media representations for assessing normative standards depends in part on how accurately media reflect "on-the-ground" resource conditions. This study compared encounter standards based on still and moving pictures to assess movement effects. The study location was the Jungmoeri area of Mudeungsan Provincial Park (MPP) in Korea. A total of 50 college students participated in a laboratory experiment where they evaluated still and moving pictures constructed using Photoshop and Flash computer programs. For the maximum acceptable number (MAN), however, there was no significant difference of ratings between still and moving pictures, and the overall encounter norm curves were nearly identical. There were some "method findings" for ordering effects and percent of people moving, but for a resource manager developing standards there was no advantage to the more complex logistics of using moving pictures to assess this particular impact. The trade-offs of using more sophisticated media are discussed, and more research is needed to further explore factors such as movement of sound in evaluation of other resource conditions.

The appearance of Internet, the 5th medium which has succeeded newspaper, magazine, TV, radio, creates WEB MAGAZINE to overcome the restriction of space and time. This paper has conducted the contents and visual points of view in webmagazine. Through case study, the following and identify for the analysis of the webmagazine contents and visual format. Firstly, communiation at webmagazine is carried out at the user-centered atmosphere. Secondly, Even through an aesthetic is emphasized in the webmagazine, when web designer compose of the web site, it is necessary to find the proper methodology under the basis of users behavior Thirdly, Although webmagazine required the visual form, we should know that the evaluation of webmagazine should be implemented by users. Therefore, webmagazine should be designed by the user-centered layout.

The present study sought to shed light on specific designs and strategies by investigating the impact that team project-based learning approach using Naver Band had on learning outcomes specifically, on satisfaction and achievement. Variables of perceived usefulness and perceived ease of use were chosen as critical predictors of the learning outcomes. 70 undergraduate students were divided into 18 groups and instructed to work on a team project using Naver Band for 6 weeks. Data analysis was completed using descriptive statistic analysis, correlation analysis, hierarchical regression analysis. Also, descriptions of Band from team reflection journal were analyzed. The major results of the study are as follows: first, perceived usefulness was the significant predictor of satisfaction and achievement. Second, 5 functions were revealed as strengths about Band.

전 세계적으로 중요한 담수 자원인 지하수의 미세플라스틱 오염에 대한 우려가 커지고 있다. 지하수 환경에서 미세플라스틱의 오염을 예측하고 평가하기 위해 대수층 내 현장 실태조사가 수행 중에 있으며, 실험실 규모의 컬럼 실험을 통해 지하수에서 미세플라스틱 이동 메커니즘을 조사하는 연구들이 수행되고 있다. 이러한 연구들은 많은 개수의 분석 시료를 동반하며, 환경 중 미세플라스틱 정량분석을 위해서 고가의 분석기기(라만분광기, 푸리에 변환 적외선(FTIR) 분광기, 열분해 가스크로마토그래피 질량분석기)를 사용하여 플라스틱의 종류를 판별하고 개수를 측정하고 있다. 또한, 컬럼 실험을 수행한 대부분의 선행 연구에서는 미세플라스틱 정량분석을 위해 탁도 분석, 분광광도계를 이용한 흡광도 분석, 현미경을 이용한 계수 방법 등을 이용하여 고가의 분석기기를 사용하지 않고 연구를 수행하였다. 하지만, 이러한 방법들은 유체 속 다른 물질이 포함되어있을 경우에 민감하고 농도를 비율 혹은 개수로 표현하기 때문에 질량 측면에서 미세플라스틱의 농도를 과소·과대 평가할 수 있다. 특히, 현미경을 이용한 계수 방법의 경우에는 분석에 많은 시간이 소요된다는 단점이 있다. 위에 언급한 다양한 분석법들의 단점들을 보완하기 위하여, 본 연구에서는 대수층 내 미세플라스틱 이동 특성을 규명하기 위한 실내 실험에 사용될 수 있는 형광이미지 기반의 미세플라스틱 정량분석법을 개발하였다. Nile Red 형광염료를 이용하여 미세플라스틱을 염색하고 사진을 촬영하여 미세플라스틱 시료의 질량과 미세플라스틱 형광이미지의 형광강도 간 상관관계를 분석하였다. 또한, Nile Red로 염색된 미세플라스틱 입자의 수중 노출 테스트를 진행하여, 실내 대수층 모의실험 시 미세플라스틱 질량을 정량화할 수 있는 적용 가능성을 평가하였다. 상관 분석 결과, 미세플라스틱 질량과 이미지의 형광강도는 높은 상관관계를 보였으며, 수중 노출 실험 전과 후의 미세플라스틱 입자의 형광강도 차이는 미미한 것으로 나타났다. 이러한 연구결과를 통해 본 연구에서 개발된 미세플라스틱 정량분석 방법이 포화 다공성 매체로 구성된 컬럼실험 시 유출수의 미세플라스틱 질량 추정에 유용하게 사용될 것으로 생각되며, 대수층 내 미세플라스틱의 이동 특성 규명 연구에 많은 도움이 될 것으로 기대된다.

The purpose of this study is to investigate the predictability of variables among technology easy to use, perceived usefulness, and technostress that had impacts on kindergarten preservice teachers' technology intention to use. For this study, the survey data collected by 64 students who were enrolled in the kindergarten preservice teacher education were analysed by using multiple regression analysis. The results of this study showed as follows. First, technology easy to use significantly affected perceived usefulness. Second, technology easy to use negatively affected technostress. Third, perceived usefulness significantly affected technology intention to use while technostress negatively affected it. From this results, it is revealed that various technology training opportunities would be provided for improving preservice teachers' technology intention to use and lessing preservice teachers' technostress. Furthermore, effective teaching-learning strategies for utilizing technology as an educational media should be developed in the early childhood educational environment.

The internet has the capabilities of supporting and facilitating several forms of consumer interaction including one-to-one, one to many, or many-to-many interactions. Especially, previous studies revealed that the Online Word-of-Mouth communication is widely used as a source of customer's information seeking and purchase decision making. Even with this importance of the Online Word-of-Mouth communication on internet, few research has systematically addressed the issue. This study investigates the effect of interpersonal communication on consumers' information search activities and develops a model that depicts the key antecedents and mediating variables of interpersonal communication in internet shopping environment. The results are as follows: First, choice uncertainty, perceived risk, and knowledge uncertainty play an important role for perceived usefulness. Second, perceived usefulness has directly affected interactive communication of consumers' communication style. Thus, it is essential for internet companies to find ways to encourage their customers to engage in word-of-mouth communication.

본 연구는 인터넷 이용수준이 전통적 미디어의 이용수준에 미치는 영향과 수용지들의 미디어 소비 패턴에 대해 살펴보았다. 미디어 대체이론, 이용과 충족이론, 미디어 레퍼토리 연구를 바탕으로 인터넷 이용이 전통적 미디어의 이용에 미치는 영향을 중심으로 개인들의 정보와 오락 미디어 레퍼토리, 인터넷 레퍼토리에 영향을 미치는 사회적, 심리/태도적 변인과 인구통계학적 특징 등도 검토하였다. 이를 위해 전국에 있는 18세 이상 성인들을 대상으로 성별, 나이별, 지역별 층화표집방법을 이용해 표본을 추출하고 500개의 유효 서베이 설문지를 수집하였다. 데이터의 분석결과, 인터넷 이용정도가 다른 매체에 미치는 영향은 각 미디어별로 세 가지 다른 양상을-상호보완적 영향, 대체 치환의 영향, 그리고 영향을 받지 않음-보였으나 대체로 인터넷은 다른 미디어의 대체 미디어라기보다는 보완적인 매체로 현재 이용되고 있음이 나타났다. 또, 전반적인 미디어 이용시간 측면에서는 인터넷을 많이 이용하는 응답자일수록 오락과 정보 미디어 레퍼토리 크기가 더 컸던 것으로 나타나, 현재까지는 인터넷이 다른 미디어와 상호 보완하는 양상, 피들러(Fidler)의 미디어 변형이론 가운데 공존 공진화 현상을 보여주었다. 응답자들은 평균 2.01개와 2.25개의 오락과 정보 미디어 레퍼토리를 가졌으며 텔레비전, 신문, 인터넷을 두 미디어 레퍼토리의 3대 주요 미디어로 꼽았다. 또한 인터넷 레퍼토리와 사회적, 태도적 변인들간의 상관관계는 최근의 이용 충족이론과 미디어 레퍼토리 연구에서 나타났던 결과들과 일치해 사회적, 심리 태도적 요인들이(친밀도, 접근성, 유용성, 여가시간) 미디어 레퍼토리의 크기에도 영향을 미친다는 사실이 검증되었다.

With the emergence of SNS, TV, newspapers and radio, which are one-way communication media, have become less important. Therefore social networking enables social networking beyond the constraints of time and space, and communication and emotional communication required for social relations have emerged as a factor in the importance of social media. Social media, which is based on rapid connectivity and scalability, is an medium of expression that is advantageous for companies and consumers to communicate more easily than traditional advertising media. Advertising can form a consensus that consumers and companies can create an atmosphere of friendly conversation because of the social media that has the efficiency of communication. This study compares two ads. One is the advertisement of 'Bear and Hare', an animation of John Lewis department store in the UK, where a new form of advertising marketing strategy is fused with emotional storytelling and social media. The second is an advertisement of LG, 'I love you LG' to be. Social media should be remembered as a warm and loving company in the heart of customers through open communication with customers, rather than companies that pursue merit profits by using social media ads as a medium of emotional transmission to consumers. It is a study on useful advertising strategy that can pursue the sales of the company at the same time.
