본 연구에서는 민주적 학교문화가 청소년의 공동체의식에 미치는 영향을 종단적으로 분석하였다. 종단적인 분석을 위해 한국교육종단연구 2013(Korea Education Longitudinal Study, KELS) 자료 중 3차년도(2015년, 중1)부터 7차년도(2019년, 고2)까지의 자료를 활용하였으며, 잠재성장모형(Latent Growth Modeling) 방법을 사용하였다. 분석 결과, 첫째, 중1 시점부터 고2 시점까지 우리나라 청소년의 공동체의식은 증가하는 경향이 있는 것으로 나타났다. 둘째, 민주적 학교문화는 중1부터 고2까지 모든 시점의 공동체의식에 유의미한 영향을 미쳤다. 셋째, 청소년의 사회적 관계(부모, 또래, 교사와의 관계), 다양한 활동 경험(자치 활동 경험, 봉사 활동 경험), 사회경제적 배경(성별, 부모의 교육 수준) 변수들도 공동체의식에 유의미한 영향을 미치는 것으로 나타났다. 본 연구는 민주적인 학교문화가 청소년의 공동체의식에 긍정적인 영향을 줄 수 있다는 사실을 실증적인 분석을 통해 확인하였다는 점에서 의의가 있다. 공동체의식과 같은 시민의식의 발달 과정에는 청소년들이 주로 생활하는 학교라는 공간의 문화적 환경이 매우 중요하다는 사실을 알 수 있다. 청소년의 공동체의식 발달을 위해 우리의 교육 환경을 더욱 민주적으로 만들어가기 위한 노력이 필요하다. This study analyzed the influence of democratic school culture on adolescents' sense of community based on data from the Korean Education Longitudinal Study (KELS) 2013. Latent growth modeling was used to longitudinally analyze the effects of democratic school culture on adolescents' sense of community. First, it was found that adolescents' sense of community tends to increase from the 7th to the 11th grade. Second, democratic school culture has a significant influence on the sense of community at all times from the 7th grade to the 11th grade. Third, the social relationships experienced by adolescents, activity experiences, and socioeconomic background also significantly impact the sense of community. This study demonstrates that democratic school culture can positively affect adolescents' sense of community. It is important to strive to further democratize the educational environment in order to develop adolescents' sense of community.

고전수필(古典隨筆) 개념 정립을 위한 시론(試論)

주재우(朱才佑) ( Joo¸ Jae-woo ) 한국어문교육연구회 2020 어문연구(語文硏究) Vol.48 No.4

이 연구는 고전수필의 개념이 성립하는지에 대한 물음에서 출발하여 문학교육을 위한 고전수필의 개념을 정립하기 위한 시론이다. 이를 위해 수필의 개념이 자리 잡은 1930년대 수필론에서 수필 개념을 탐색하였다. 그 결과 수필의 필수적 조건으로 무형식, 비전환표현, 형상성 등을 도출하였고, 필자의 수준 높은 삶에서 글이 나와야 한다는 점을 충분조건으로 도출하였다. 이를 바탕으로 고전수필의 개념을 정립하고자 했다. 1930년대 수필론에서는 고전수필을 인정하지 않았지만 고전수필은 그 이전부터 인식된 적도 있다. 다만 수필이라는 기표에 집착해서 고전수필을 이해하거나 미분류의 글인 잡저로 한정할 경우 고전수필의 범위는 협소해질 수밖에 없다. 반대로 비허구적 산문 전체를 수필로 간주할 경우 교술과 수필의 경계가 사라진다. 따라서 수필의 무형식을 ‘형식의 없음’이 아니라 ‘형식의 자유로움’으로 이해하고 이에 더하여 ‘비전환표현+형상성’을 갖춘 근대 이전의 글로 보았을 때 고전수필은 문체나 형식에 구애되지 않고 확장될 수 있다. This study starts with the question of whether the concept of classical essay is possible. To this end, we explored the concept of essay in essay theory in the 1930s when the concept of classical essays established. The essential requirement of an essay are form of no-form, non-fictional expression, and a character of shape. Although the essay theory of the 1930’s did not recognize the existence of classical essays, classical essays have been recognized since then. However, if the classical essay are recognized by articles named essays or unclassified articles, the scope of classical essays will inevitably be narrow. Moreover, the whole of nonfictional prose cannot be recognized as an essay because didactic genre and essay are not same. The intangible formula of an essay should be understood not as the absence of a form but as the freedom of form. Therefore, classical essays can be regarded as works with a free form, non-fictional expression, and a character of shape before modern times.

<P><B>Abstract</B></P> <P>The huge production of waste agricultural and biomass products has a negative impact on the environment, thus necessitating economic and environmental recycling of abundant bio-waste materials to useful materials. To recycle and convert bio-waste materials, a sustainable nanoporous carbon from bio-waste (peanut shell, gingko, and metasequoia leaves) is facilely synthesized via one-step carbonization. Carbonized samples contain a small quantity of metal and non-metal residues (including sulfur and phosphorus), resulting in naturally doped porous carbon. The porosity, morphology, and composition of the nanoporous carbons were investigated and compared with those of commercially available activated carbon. Pure component adsorption isotherms of CO<SUB>2</SUB>, CH<SUB>4</SUB>, and N<SUB>2</SUB> were also measured at 40 °C up to1 bar for all samples. These data were used to estimate the separation selectivity for CO<SUB>2</SUB>/CH<SUB>4</SUB> and CO<SUB>2</SUB>/N<SUB>2</SUB> 1:1 binary mixtures and pressures according to the ideal adsorbed solution theory (IAST) model. Carbonized gingko leaf had the lowest SSA and pore volume but the highest S and P contents, with the highest average selectivity of 506 and 54 for CO<SUB>2</SUB>/N<SUB>2</SUB> and CO<SUB>2</SUB>/CH<SUB>4,</SUB> respectively. This implies that the composition of the prepared carbon materials plays a significant role in their CO<SUB>2</SUB> adsorption and separation ability, rather than their textural properties.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Sustainable microporous carbon from waste products was developed. </LI> <LI> Special elemental composition role of porous carbon was investigated. </LI> <LI> The developed porous carbon achieved 3.63 mmol/g of CO<SUB>2</SUB> at 1 bar and 40 °C. </LI> <LI> Enhanced CO<SUB>2</SUB>/N<SUB>2</SUB>(506) and CO<SUB>2</SUB>/CH<SUB>4</SUB>(54) selectivity was achieved. </LI> <LI> Synergetic effect between P and S elemental composition was noticed. </LI> </UL> </P>

The present research has two objectives. First, we introduce a new framework of design management proposed by Heather Fraser, the Director of Rotman Designworks. It comprises three gears: (1) user understanding, (2) concept visualization, and (3) strategic business design. Second, we investigate the key requirements that are necessary to apply the new framework to Korean companies. We collected fifty reports about the five special lectures from a new product development course at a university in Korea. These lectures were given by three designers and two product managers. We used interpretative analysis and followed three process of qualitative analysis of transcription, coding, and theme discovery. We derived specific requirements for applying design management to Korean companies: (1) experience design, (2) collaboration, and (3) trial and error. We introduced a novel design management framework and clarified the requirements how to successfully apply it to Korean companies. These findings imply that, firstly, executives and practitioners need to improve mutual communication and, secondly, corporations and agencies respect each other in their partner relationships.

Jaewoo Shim,Heechul Lee,Sinhwa Lee 현대문법학회 2020 현대문법연구 Vol.108 No.-

The purpose of this study is to investigate affective factors that distinguish the high spoken English use group from the low spoken English use group among Korean EFL middle school students. This study focuses on the variables of communication strategy, willingness to communicate, self-concept, motivation, and anxiety. A questionnaire on communication strategy, willingness to communicate, self-concept, motivation, anxiety, and the use of spoken English was designed and administered to 112 students of eighth grade in a province. The findings of the study are as follows: (1) the middle school students’ levels of extrinsic motivation and speaking anxiety were high, while the levels of self-concept, intrinsic motivation, and the use of spoken English were low, (2) the highest positive relationship was found between willingness to communicate (WTC) and the use of spoken English, while the highest negative relationship was observed between speaking anxiety and the use of spoken English, (3) willingness to communicate (WTC), academic self-concept, and communication anxiety were statistically significant factors that distinguished the high spoken English use group from the low spoken English use group. Based on the findings, some suggestions were made in regard to helping students improve their use of spoken English.

Understanding Professors’ Online Course Design Activity: Focusing on Converting Existing Face-to-Face Course to Online Course

Jaewoo Do,Jinhee Kim 보안공학연구지원센터 2016 International Journal of Software Engineering and Vol.10 No.11

The effectiveness and attractiveness of online learning have proved by many researcher. The flexibility and convenience are typical benefits of online learning. With these benefits of online learning, a great deal of learning occurs in the online setting. Nowadays, universities have been offering many online classes. Particularly, universities are asking professors to re-design existing face-to-face courses into online courses to meet students’ growing demands for online course. However, several challenges of online learning also have identified. The lower interactions between a teacher and a student, and a student and a student than face-to-face learning is one of the challenges. Additionally, several research found that teaching and assessment techniques and method that served well in the traditional classroom don’t work quite well in online course. In online learning, a lot of features related to teaching and learning have changed. With these challenges, professors who have taught face-to-face course are having difficulty converting existing face-to-face course into online course. Thus, it is important to investigate how to design an effective online course to support professors’ online course design. In this study, we analyzed the design process of converting face-to-face course to online course. We collected three converting cases and analyzed those cases with activity system analysis method. As a result, we found design challenges related to converting existing course to online course and professors’ and university’s practical difficulties in online course development. This result of this study will help professors, instructional designers, and universities to design and develop successful online course.

Opportunistic Reporting-based Sensing-Reporting-Throughput Optimization Scheme for Cooperative Cognitive Radio Networks

( Jaewoo So ) 한국인터넷정보학회 2017 KSII Transactions on Internet and Information Syst Vol.11 No.3

This paper proposes an opportunistic reporting-based sensing-reporting-throughput optimization scheme that maximizes the spectral efficiency of secondary users (SUs) in cooperative cognitive radio networks with a soft combining rule. The performance of cooperative spectrum sensing depends on the sensing time, the reporting time of transmitting sensing results, and the fusion scheme. While longer sensing time and reporting time improve the sensing performance, this shortens the allowable data transmission time, which in turn degrades the spectral efficiency of SUs. The proposed scheme adopts an opportunistic reporting scheme to restrain the reporting overhead and it jointly controls the sensing-reporting overhead in order to increase the spectral efficiency of SUs. We show that there is a trade-off between the spectral efficiency of SUs and the overheads of cooperative spectrum sensing. The numerical results demonstrate that the proposed scheme significantly outperforms the conventional sensing-throughput optimization schemes when there are many SUs. Moreover, the numerical results show that the sensing-reporting time should be jointly optimized in order to maximize the spectral efficiency of SUs.
