This study investigates the use of cohesive devices in the corpus of Korean college students’ compositions. In particular, it attempts to provide a comprehensive analysis of the lexico-grammatical contexts in which cohesive referential devices are employed in argumentative essays. For this purpose, a Korean EFL corpus and a native speaker corpus were analyzed based on Gray’s (2010) coding scheme. The coding scheme included variables such as the place and unit of the antecedent, the grammatical role and place of demonstratives, and their preceding or following structures. The results of the analysis showed that Korean EFL learners and native writers were similar in that they tended to use demonstrative pronouns as a subject and demonstrative determiners as objects/complements. Besides this general tendency, non-prototypical uses of the determiners were observed. The learners’ corpus manifested an overuse of an extended antecedent which could reduce the clarity of meaning. The most frequent verb following demonstrative pronouns was the copula (i.e., be) in both corpora. Finally, the learners tended to use a much smaller number of abstract/shell nouns than their native speaker counterparts.

The purpose of this research is to evaluate Seoullo 7017 based on Universal Design (UD) principles and guidelines. To derive UD principles applicable to the site context, we used the 2017 Seoul Universal Design Guideline and assessment index provided by the Universal Design Research Center and established 11 evaluation criteria. With respect to research methods, a literature review and on-site field survey were applied, through which we derived UD principles and evaluation criteria to identify UD problems. The 11 evaluation criteria consist of pedestrian space, facilities, access, main entrance, parking lots, trails, restrooms, convenience facilities, information facilities, rest areas, and playgrounds, and these were associated with UD principles for evaluation. As a result, the main entrance had the highest UD score, while parking lots had the lowest in terms of equity, safety, simplicity, and accessibility. Restrooms received a lower UD score because of poor conditions of security and alert systems. Rest areas were found to be uncomfortable for disabled people. With respect to the internal trails, we found the lack of braille block and irregular placement of planting pots made blind people uncomfortable when walking. In terms of UD principles, flexibility received the highest score, followed by amenity, equity, simplicity, tolerance, accessibility, and safety. Flexibility received the highest score, owing to the provision of proper information about convenience facilities and trails, while safety received the lowest, based on poor access to parking lots, inadequate paving materials and colors, and a lack of 24-hour security systems. We hope this research contributes to improving the universal design, so that people are not discriminated against in the use of the park in terms of age, sex, or physical disability. We expect the study to help facilitate empirical studies to verify UD principles and provide improved quality of UD for Seoullo 7017.

In this study, polyaniline (PANI)/graphene nanosheet (GNS) composites were synthesized through chemical oxidation polymerization by changing the weight ratio of aniline mono-mers. To examine the morphological structure of the composites, scanning electron micros-copy and transmission electron microscopy (TEM) were conducted. TEM results revealed that fibril-likePANI with a diameter of 50 nm was homogeneously coated on the surface of the GNS. The electrochemical properties of the composites were studied by cyclic voltam-metry in 1 M H2SO4 electrolyte. Among the prepared samples, the PANI/GNS (having 40 wt% aniline content) showed the highest specificcapacitance, 528 Fg-1, at 10 mVs-1. The im-proved performance was attributed to the GNS, which provides a large number of active sites and good electrical conductivity. The resulting composites are promising electrode materials for high capacitative supercapacitors.

이 연구에서는 매체의 혼용으로 스토리텔링을 진행하는 작품에서 공통적으로 사용된 ‘설득력 있는 사운드’를 추출하고, 형태를 중심으로 한 분류, 서사적 내러티브의 구조에 따른 분류, 구현방법에 있어서의 분류를 진행한다. 그 이후 추출 된 세부 키워드를 정리하고 세분화 시켜 특성들을 분석하고 나열해 본다. 이러한 일련의 과정을 통하여 사운드 이펙트의 제작에 있어 인지적 요소에 의한 평가의 기준을 제시하고자 하며, 제작 초기부터 설득력 있는 사운드 이펙트를 선택할 수 있는 기준을 마련하고자 한다.

Gochujang samples with essential oils were evaluated for sensory including taste and, smell during various storage periods with the aim of developing improved high value-added products. The sensory testing was performed on Gochujang with 0.005% Zanthoxylum piperitum and Chrysanthemum indicum essential oils, extracted through steam distillation. During storage at 4 and 20℃ for 8 weeks, sensory testing was performed at 0, 1, 2, 4 and 8 weeks by trained panelists. Overall quality decreased in Gochujang samples containing Z.piperitum essential oil and increased in samples containing Cindicum essential oil, at 4 and 20℃. Samples stored at 4℃ were quality more then those stored at 20℃. Sensory evaluation was highest for Gochujang with Cindicum essential oil stored at 4℃. It is concluded that functional Gochujang can be developed by adding small quantities of essential oils. Increasing the amount of essential oil added is likely to affect the innate taste and flavor of Gochujang.

최근 음악을 기반으로 한 게임이 각광받기 시작하면서, 음악이 게임의 중요한 콘텐츠로 자리를 잡게 되었다. 이러한 게임 중 ‘노트’를 게임 플레이에 적극적으로 활용하여 음악을 시각화한 게임들이 많은 인기를 끌고 있다. 그러나 이러한 게임에서 어떻게 음악이 시각화 되어 게임이 디자인 되는지에 대해 음악 이론 관점에서 접근한 연구는 찾아보기 어렵다. 본 논문에서는 노트가 활용된 게임에서 음악이 어떻게 시각화 되었는지에 대한 시각화 요소를 음악 이론, 미디 이론을 기반으로 도출한다. 또한, 도출된 요소들을 분석함으로서 노트가 활용된 게임이 악보나 미디에서 음악의 시각화 방식과 비교하여 어떤 특징이 있는지 정리한다. 이 논문은 노트가 활용된 게임에서 음악의 시각화 요소를 음악이론에 근거하여 처음으로 분류하였고, 이러한 연구는 앞으로 음악을 기반을 한 게임 디자인에 가이드라인이 될 것으로 예상된다.
