This paper examines the effects on academic achievement, scientific process skills and affective domain for elementary students learning the 'Chicken life cycle' through traditional science class versus a smart media based STEAM approach. Students designed and built a hatching jar and created a smart media content for chickens using time-lapse technology. This STEAM program was developed to improve their scientific concepts of animals over nine periods of classes using integrated education methods. The experimental study took place in the third grade of public schools in a province, with the STEAM approach applied in 2 classes (44 students) and the traditional discipline approach implemented in 2 classes (46 students). The STEAM education significantly influenced the improvement of academic achievements, basic scientific process skills and affective domain. The results suggest that this STEAM approach for teaching scientific concepts of animal life cycles has the performance in terms of knowledge, skills and affect gain achievements in elementary school students' learning when compared to a traditional approach. Moreover, the smart media based STEAM program is helpful to lead students to engage in integrated problem-solving designs and learning science and technology.

Paecilomyces tenuipes (P. tenuipes) is a fungus cultivated artificially by South Korean researchers, utilizing rice bran as its substrate. The increased demand for this fungus has not been met with successful cultivation methods for fruiting body production in natural environments. Therefore, we tested the effect on the growth of P. tenuipes using a Solid media based on pests. In this results, the Solid media based on M.alternatus was effective in increasing the growth of P. tenuipes and the content of cordycepin. Moreover, we confirmed the conditions for manufacturing a Solid media based on M.alternatus for P. tenuipes growth. We suggested that the growth-promoting compounds offers valuable insights for optimizing fungal cultivation conditions, thereby enhancing productivity and contributing to a broader understanding of fungal physiology in varying nutritional environments.

커뮤니케이션학에서 통약가능한 이론적 대중매체체계론이 부재하다는 점은 비교연구를 비롯한 경험연구에서 난점으로 남아있었다. 본 연구는 하버마스의 2단계 사회론을 수정한 수정된 2단계 사회론을 바탕으로 정적 일반대중매체체계론을, 루만의 경계이론과 들뢰즈 가타리의 배치이론을 종합한 경계배치이론을 바탕으로 동적 일반대중매체체계론을 제안한다. 정적 일반대중매체체계론에서 대중매체체계는 일반화된 언어를 조정매체로 하는 문화체계의 하위사회체계로서 여타 하위사회체계 및 생활세계와 상호침투한다. 동적 일반대중매체체계론에서 대중매체체계는 다른 모든 하위사회체계의 경계로서 하위사회체계의 자기관계적 관찰을 생활세계에 의한 타자관계적 관찰과 접목시킨다. 또 대중매체체계는 체계와 생활세계 간의 상호침투를 매개한다. 특히 대중매체체계에서의 수행은 체계를 생활세계로 탈영토화하고 생활세계를 체계로 재영토화한다. 일반대중매체체계론은 다양한 경험적 대중매체체계론에 통약가능성을 제공해주고 편향되게 연구대상을 설정하지 않도록 도움을 줄 것으로 기대된다.

This study aimed to investigate the mediating effect of the screen media time of young children on the relationship between mothers' reasons for allowing young children to use screen media and their children's ability to regulate screen media. The participants consisted of 614 children aged 5-6 (312 boys and 302 girls), and all the survey questions were answered by their mothers. Descriptive statistics, Pearson's correlation, structural equation modeling, and bootstrapping analysis were employed to analyze the data using SPSS 25.0 and Mplus 8.6. The results were as follows. First, mothers' educational and ritualized reasons for allowing young children to use screen media and children's screen media time directly affected young children's ability to regulate screen media. Second, children's screen media time mediated the relationship between mothers' educational and ritualized reasons for allowing their children to use screen media and children's ability to regulate screen media. When mothers permitted their children to use screen media for educational purposes, their children were likely to spend less time on screen media usage which, in turn, increased their ability to regulate screen media. Conversely, the more mothers allowed their children to use screen media for ceremonial purposes, the more time their children spent on screen media and the less ability they had to regulate screen media usage. These outcomes suggest that, to improve children's screen media regulation ability, mothers must not routinely allow their children to use screen media and should manage their children's screen media time.

A diverse group of plant-growth promoting bacteria were isolated in button mushroom (Agaricus bisporus) media to investigate the plant-growth promoting traits of compounds including indole acetic acid (IAA), ammonia, 1-aminocyclopropane-1-carboxylic acid deaminase, siderophore, and hydrogen cyanide. Twenty-one bacterial strains showing positive effects for all the test traits were selected and classified to confirm bacterial diversity in the media habitat. Plant-growth promoting traits of the isolates were also assessed. All strains produced IAA ranging from 20 ㎍/mL to 250 ㎍/mL. Most of the isolates produced more than 80% siderophore. Four strains (Pantoea sp., PSB-08, Bacillus sp., PSB-13, Pseudomonas sp., PSB-17, and Enterobacter sp., PSB-21) showed outstanding performances for all the tested traits. In a bioassay of these four strains using mung bean plant, the best growth performances (23.16 cm, 22.98 cm, 2.27 g/plant, and 1.83 g/plant for shoot length, root length, shoot dry weight, and root dry weight, respectively) were obtained from the plants co-inoculated with Bacillus sp., PSB-13. The resultant data indicate that button mushroom media have got a diverse group of bacteria with plant growth promoting abilities. Thus, the media could be a good recycling resource for using to an effective bio-fertilizer.

본 연구는 개인의 사회적 발전 및 안녕에 미치는 소셜 미디어의 영향력을 분석한다. 기존 연구에서 소셜 미디어는 사회적 심리적 자원이 결여된 개인이 사회적 연결망을 확장하고자 할 때 효과적인 수단으로 논의되어 왔다. 이러한 점에 착안하여 본 연구는 북한이탈주민의 소셜 미디어 이용에 주목한다. 우리사회에서 북한이탈주민은 폐쇄적인 사회 연결망을 가진 것으로 인식된다. 이들은 사회구조적인 요인으로 인해 새로운 커뮤니티를 만들거나 그 속에서 관계를 확장하고자 하는 것에 소극적이다. 따라서 본 연구는 북한이탈주민의 소셜 미디어 이용이 사회적응에 미치는 영향력을 분석한다. 특히 정서적 상태에 따른 소셜 미디어 이용이 남한생활 만족도에 어떠한 영향을 미치는지에 초점을 맞춘다. 본 연구는 북한이탈주민의 남한생활 만족도에 미치는 소셜 미디어의 효과는 정서적으로 취약한 조건일 때 더욱 크다고 가정한다. 구체적으로 자아존중감이 낮거나 불안감 수준이 높을 때 남한생활 만족에 미치는 소셜 미디어의 영향력이 더욱 클 것이라고 본다. 또한 본 연구는 일반인을 대상으로 동일한 분석을 실시한 후 그 결과를 북한이탈주민의 경우와 비교한다. 분석 결과 다소 흥미로운 결과가 도출되었다. 북한이탈주민은 불안감이 강한 사람이 약한 사람에 비해 남한생활 만족도에 미치는 소셜 미디어의 영향력이 크지만 자아존중감의 경우 자아존중감이 높은 사람이 낮은 사람에 비해 남한생활 만족도에 미치는 소셜 미디어의 영향력이 더 큰 것으로 확인되었다.
