Effects of the special media on the mycelium growth in Agaricus campestris were studied. The results might be summarized as follows: 1. The mycelium growth fo Agaricus campestris were scarecely stimulated on the Peptone basal medium which was added 0.5gr. of Peptone and Dextrose basal medium which was added 1.5gr. of dextrose during the culture for 144 hours. 2. The mycelium of Agaricus campestris on the media which was added the several kinds of vegetable extracts showed a considerable growth for 144 hours. The order is as follows; Carrot-basal medium(4ml./100ml.)>Tomato-basal medium(2ml./100ml.)>Spinach-basal medium(3ml./100ml.). However, the spinach-basal medium among these three media were no significant difference.

This paper describes the effects of slider behavior over patterned media. The flying characteristics of a slider over patterned media are different from slider flying behavior over conventional plane disk. In order to perform the most realistic simulation of slider flying characteristics over patterned disk surfaces, our simulation approach virtually distributes the grooves on the slider ABS instead of on the disk surface. Also, we define SSFA which is steady-state slider flying attitude. The results show that the more patterned size is small and height is large, the more increased SSFA is. Also if patterned distance is small, then SSFA is increased. In addition, we analyzed the effects of patterned shapes.

디지털 미디어를 활용한 스마트 광고는 지난 수년간 매우 활발한 연구 분야로 자리하고 있으며 끊임없이 새로운 형태의 스마트 광고가 등장하고 있다. 본 논문은 스마트 광고의 한 형태인 래플(Raffle)광고에 대한 이해의 틀을 마련하고자 광고메시지 유형과 브랜드 친숙도의 상호작용 효과에 대해 다루고 있다. 본 연구의 가설을 검증하기 위해 2(래플광고 메시지 표현 유형: 한정된 시간vs. 타인의 응모현황) × 2(브랜드 친숙도 수준: 고 vs. 저) 실험설계를 적용하였다. 연구결과 광고메시지 표현 유형이 래플광고효과에 미치는 영향은 브랜드 친숙도 수준에 따라 달라지는 것으로 나타났다.

본 연구는 미디어 프레임과 개인 프레임이 신문 기사에 대한 독자의 태도와 공정성 지각에 미치는 영향에 대해 알아보고자 했다. 연구 1에서는 한국의 2008년 촛불시위 기사 그리고 연구 2에서는 한국 정부의 4대강 사업 기사에 대한 프레임 효과를 알아보기 위해, 대학생을 대상으로 각 이슈에 대하여 3(미디어 프레임: 호의적 vs. 비호의적 vs. 중립적 헤드라인) × 3(개인 프레임: 호의적 vs. 비호의적 vs. 중립적 신문사) 집단 간 실험 연구를 하였다. 그 결과, 두 연구에서 각 이슈에 대한 언론사의 지각된 태도에 미디어 프레임과 개인 프레임의 유의미한 효과가 있었지만 상호작용은 유의미하지 않았다. 기사의 지각된 공정성에서는 개인 프레임이 부분적으로 유의미한 효과를 보인 반면, 미디어 프레임의 효과나 두 프레임의 상호작용은 없었다. 이러한 결과는 기사에 대한 개인의 태도와 공정성 지각이 기사 내용 뿐 아니라 기사의 출처에도 영향을 받을 수 있음을 보여준 것이다. 또한 텍스트 이외에도 헤드라인으로 조작한 미디어 프레임의 효과 역시 재확인하였다.

Purpose - One of the main objectives of this paper is to identify the most effective type of social media and to analyze the priority of blogs by their informational attributes in the aspect of their impacts on word-of-mouth intention(WOM) in on-line markets. Research design, data, and methodology - We set 'attitude' variable in the middle to see if there is mediating effects between blog information and word-of-mouth intention. We conducted a survey by questionnaire and received 206 answers. Employing the OLS statistical methods through the SPSS package, we tested our hypotheses. Results - Some of the main results are the followings. First, blog, micro-blog, and profile-based services showed significant effects on WOM, while Internet community and mini-homepages are not significant. Second, blog has positive impacts on WOM. Third, attitude has perfect mediating effects between blog and WOM. Fourth, in terms of effects on WOM, interactivity shows the first priority and reliability and usability follows. Finally, attitude has a more significant effect for users of 3 types of blog compared with those of 2 types. Conclusions - In this paper, we analyzed the effects of social network services by type and identified the priority among various attributes of information contained in blogs. It would provide businesses with viable strategic options to establish public relations in their sales promotion.

Diversity of available communication media has increased as the use of Internet and mobile technology increased rapidly. The traditional media tend to transform their roles and functionality. This change brings about the expansion of the span of media to be selected by users. In this study, we examined the characteristics of emerging communication media use based on Niche Theory. Online communication media in this study include Internet messenger, mobile phone, and e-mail. We also analyzed the relationship between the nature of task and the selection of communication media, that is, the effects of communication contexts(formal vs. informal, notification vs. request, superior vs. inferior) where by the communication partners are involved. The result of this study, mobile phone had the highest niche competitive superiority in all communication contexts, and internet messenger and e-mail made difference according to communication contexts. Also, we can notify internet messenger and e-mail have a mutual substitutive relationship by analysis of niche overlap.

The purpose of this study is to examine the effects of university students' media sports immersion experience through social media on exercise immersion and exercise continuation. This research target was first selected as a population of university students who have contacted media sports aged 20 or older living in Gwangju Metropolitan City in 2019. The sampling procedure was divided into five parts: Dong-gu, Seo-gu, Nam-gu, Buk-gu, and Gwangsan-gu in Gwangju, and 300 men and women were sampled using cluster random sampling. After individually entering coded data into the computer, the statistical program (SPSS Windows.20.0 Version) was used. The results obtained through this research process are as follows. First, it was found that university students' immersion to media sports had a partial effect on their commitment to exercise. Second, it was found that university students' immersion in media sports had a partial effect on the continuation of the exercise. Third, it was found that college students' exercise commitment has a partial effect on exercise continuation.

This study examines the relationship between social media advertisement and customer interest in the context of luxury brands. Further, this study investigates the effective ways to utilize visual types (pictorial advertisement and video advertisement) and contents types (website link and hash-tag) in social media advertising by proposing a time-series model to estimate the long-term effect of social media advertising on social search. We find that the pictorial advertisements are more effective than video advertisements, which provides a different result from previous existing research. In addition, advertisements using hashtags are more effective than web links due to efficiency of the search feature. Finally, since the number of brand fans also have a positive effect on advertising interest, it is essential to utilize social media advertising for the enhancement of customers' interests. Confirming that the effectiveness of social media advertising varies depending on how the visual contents and text are presented, this research can help marketing managers to assess predicted outcomes of using various methods of social media advertising.

This study investigated how exposure to thin-ideal images affects social physical anxiety and body-esteem in relation to individual levels of self-consciousness. A survey questionnaire was administered to a convenience sample of 119 female college students. Sixty-seven of the 119 participated in a posttest session. The mean comparisons of social physique anxiety and body-esteem scores between pretest and posttest were conducted; no significant results were found. However, when participants were divided into two separate self-consciousness groups (high vs. low), the effect of media exposure on social physique anxiety were significant.
