This study aimed to examine the recent Hanbok school uniform design directions to contribute to the distribution of Hanbok school uniforms and the accumulation of Hanbok-inspired fashion design sources. We reviewed 16 academic papers published on Hanbok school uniform designs from 1998 to 2023 and summarized the design features proposed therein. We also analyzed 172 items of Hanbok school uniform designs developed under the Hanbok school uniform promotion project hosted by the Hanbok Advancement Center between 2019 and 2022. We found that the recent Hanbok school uniform design characteristics conformed to the design directions proposed in previous studies in terms of line, color, fabric, and textile pattern. Conforming design characteristics include the following. Overall, silhouettes were straight and moderately fitting to the body. Detailed straight and curved lines from Hanbok were applied. Designs showed traditional Hanbok colors, including white, black, and navy. Machine washable cotton and various blended fabrics were used. Modernized traditional patterns such as Saekdong, cloud, and Gwae were applied to textile designs. In contrast, some characteristics of recent designs deviated from the proposed design directions. Barrel silhouettes were found in casual styles of uniform items, including sweatshirts, hoodies, and jumpers. A wider range of materials, including fleece, quilted fabric, brocade, and Jinju silk, were used. Uniforms had looser silhouettes and were made with modern washable materials to meet students’ preference for casual uniforms.

As interest in the sustainable fashion industry continues to increase along with climate issues, it is necessary to identify research trends in sustainable fashion and seek new development directions. Therefore, this study aims to analyze research trends on sustainable fashion. For this purpose, related papers were collected from the KCI (Korean Citation Index) and Scopus, and 340 articles were used for the study. The collected data went through data transformation, data preprocessing, topic modeling analysis, core topic derivation, and visualization through a Python algorithm. A total of eight topics were obtained from the comprehensive analysis: consumer clothing consumption behavior and environment, upcycle product development, product types by environmental approach, ESG business activities, materials and material development, process-based approach, lifestyle and consumer experience, and brand strategy. Topics were related to consumption, production, and education of sustainable fashion, respectively. KCI analysis results and Scopus analysis results derived eight topics but showed differences from the comprehensive analysis results. This study provides primary data for exploring various themes of sustainable fashion. It is significant in that the data were analyzed based on probability using a research method that excluded the subjective value of the researcher. It is recommended that follow-up studies be conducted to examine social trends.

본 연구는 우리나라 주요 조림수종이자 북한 산림 복구에 활용이 예상되는 자작나무(Betula platyphylla var. japonica Hara)의 용기묘 생산에 필요한 적정 용기 개발에 관한 기초 자료를 구축하고자 수행되었다. 상기 목적에 따라 실시된 실험에서 자작나무를 용적과 생육밀도가 다른 용기에서 생육시켜 생장 특성을 조사하였다. 실험용기는 국내에서 생산되는 임업시설양묘용 플라스틱 용기 6종(KK-SI 500, SI 350, KK-SI 350, KK-SI 320, KCNR-SI 300, KCNR-SI 250)을 사용하였으며, 생장이 활발한 8월과 생장이 끝난 10월 총 2회에 걸쳐 생장을 측정하였다. 수고, 근원경 생장과 묘목 전체 건물생산량은 1차와 2차 측정 모두 SI 350 용기에서 각각 32.0 ㎝, 2.81 ㎜, 1.04 g과 38.6 ㎝, 3.89 ㎜, 2.52 g로 가장 높게 조사되었다. 이에 따른 묘목품질지수 또한 SI 350에서 0.184로 가장 높은 값을 보였다. WinRHIZO 프로그램을 이용한 뿌리형태 특성 분석에서도 전체뿌리길이는 SI 350에서 3345.6 ㎝로 가장 길었고, 뿌리 투영단면적과 및 표면적, 뿌리부피 또한 전체뿌리길이와 유사한 경향을 보였다. 종합적으로, KK-SI 500보다 구 용적이 더 작은 SI 350에서 생장이 우수했다는 점에서 용기의 형태 또한 자작나무 용기묘 생장에 큰 영향을 주는 것으로 판단되었다.

This study utilized data to classify and characterize the body types of plus-size adult men aged in their 30s and 40s. Diversity is an important factor in the era of inclusive design, and discussion about size diversity to include the plus size should be accommodated. Data from 493 adult men classified as obese (with a World Health Organization criterion ≥25 BMI) were used for the analysis. The results of the study are as follows. Six independent factors were extracted using factor analysis for cluster analysis, which were then classified into five types. Type 1 (29.01%) was identified as body type I with the smallest degree of obesity. Type 2 (15.4%) was identified as body type Y with wide shoulders and a thin waist. Type 3 (14.2%) was the largest body volume (body type O), while the fourth (19.27%) identified as body type H has a large height and upper body. Lastly, type 5 (22.11%) has a long lower body and a slim abdomen, referred to as body type X. This study presents a basis for the development of various clothing sizes utilizing the body shape characteristics of plus-size men in their 30s and 40s. Follow-up research is needed to develop patterns for plus size men and to design various products.

본 연구는 우리나라의 주요 조림수종인 자작나무(Betulaplatyphylla var. japonica Hara.) 종자의 저장기간 및 온도처리에 따른 발아 특성을 구명하고자 수행되었다. 공시수종 종자는 각각 1996년, 2003년, 2012년, 2013년, 2014년, 2015년, 2016년 채집된 자작나무 종자이며, 발아실험은 5℃, 10℃, 15℃, 20℃, 25℃, 30℃, 35℃의 온도 조건에서 실시하였다. 저장기간에 따른 발아율(GR)의 조사 결과 2012 년 이전에 채집된 종자에서는 발아가 전혀 되지 않았다. 저장기간별 발아율은 2015년에 채집된 종자가 모든 온도에서 가장 높았고, 저장기간이 길어질수록 낮은 것으로 조사되었다. 온도별 발아율의 경우 1 5℃ 이하의 온도 조건에서는 모든 종자에서 발아가 전혀 되지 않고, 30℃에서 가장 높은 발아율을 보였 다. 그 외의 발아특성은 저장기간이 짧은 종자이고 발아율이 높은 온도일수록 발아기(T50)와 평균발아일 수(MGT)가 낮고 발아속도(GS)가 높은 경향을 보였다. 발아균일도(GU)는 상대적으로 고온인 35℃에서 높은 것으로 나타났다.

The present study investigated pine trees, which forms a major plantation species in Korea, with the objective of improving the survival rate of pine trees after planting. Growth responses and characteristics were assessed by controlling the level of fertilizer application, which is a basic controlling the growth of pine seedlings, to identify the optimal fertilization treatment. Pine tree seedlings were grown in 104 containers and were examined 8 weeks after planting. Stem height and were measured at 4-week intervals. In terms of fertilization treatment for 1-0 pine seedlings, the treatment group with gradually-increasing fertilizer concentration (500→1000→1000 →1000mg·L-1) had the biggest increase in stem height and diameter at the root. The survey results indicated that the increased concentration treatment group and the gradually-increasing concentration treatment group had more growth compared with that in the fixed concentration treatment group. The gradually-increasing concentration treatment group (500→1000→1000→1000mg·L-1) had the highest total dry matter production. Nine weeks after fertilization, the tips of the pine leaves turned yellow in the fixed concentration treatment group (3000mg·L-1). The same phenomenon was observed in the treatment group in which the concentration was increased to 2000mg·L-1, and in the gradually- increasing concentration treatment group, when the concentration was raised up to 2000mg·L-1. We concluded that the optimal fertilization conditions for producing healthy pine 1-0 seedlings involve fertilizing once a week with Multifeed 19 at 500mg·L-1 during the seedling period, Multifeed 19 at 1000mg·L-1 during the rapid growth period, and Multifeed 32 at 1000mg·L-1 during the maturation period.

근로시간의 단축과 일과 삶의 균형을 중요시하며 자신을 위한 시간을 갖는 사람들이 늘어나면서 대중의 워크-라이프 밸런 스(Work-Life Balance)에 대한 욕구는 증가하고 있다. 이러한 사회적 변화로 인해 개인의 예술·문화에 대한 다양한 욕구는 새로운 소비시장을 주도하고 있다. 기존의 미술 전시가 갤러리에서 그림을 전시하던 전통적인 전시의 개념에서 퍼포먼스와 인터렉션과 같은 다양한 콘텐츠를 전시하는 공간으로 다변화되고 있다. 또한 과거에 비해 기업이나 지차체에서도 문화시설 확충의 일환으로 공립미술관이나 다양한 개념의 전시공간을 제공하고 있다. 그러나 IT 기술의 발전으로 인해 대부분의 정 보를 온라인을 통해 수집하고 모든 정보들이 네트워크화되는 현시점에서 예술 분야의 전시·대관 산업은 아직까지도 오프라인에 기반을 두고 효율적인 공간 제공 서비스를 제공하지 못하고 있다. 즉 개인 창작활동가의 전시가 활발해지면서 다양한 형태의 전시공간에 대한 요구가 있지만 작가나 독립큐레이터들에게 전시 대관 서비스를 연계시켜주는 웹상의 플랫폼은 존재하지 않고 있다. 현재까지는 개별 갤러리의 홈페이지에 들어가 대관 정보를 확인해야 하는 번거로움이 따른다. 이는 다른 분야에 비해 상당히 폐쇄적인 형태로 신진 작가들의 작품 발표를 어렵게 만들며 문화·예술 분야의 발전을 저해하는 요소로 작용하고 있다. 이에 본 연구는 분산 되있는 전시공간에 대한 정보를 하나의 플랫폼을 통해 제공함으로써 작가들에게는 편리한 전시 대관 서비스를 제공하고 운영상의 어려움을 겪고 있는 갤러리나 대관 시설들에게는 해당 시설에 대한 정보 노출을 보다 효율적으로 할 수 있도록 해 줌으로써, 전반적인 전시사업의 안정성을 꾀할 수 있는 것을 목표로 한다. 이를 위해 통계적 모형의 개발을 위한 과거 자료가 없을 때 유용한 델파이 기법과 ISO/IEC 9126 소프트웨어 품질특성과 척도에 관한 표준 지침을 활용하여 사용성 테스트를 거쳐 전시 대관 웹 플랫폼 제안을 위한 기초 연구를 시행하였다. 연구의 결과로써 국내 전시대관 시설들의 데이터베이스(Database)를 구축하는데 기초자료로 활용될 것으로 기대한다.

Recycling of food wastes was tried based on fermenting and composting food wastes using a microbial consortium. Manufactured compost (using 11.3% food waste) turned out to be effective in increasing soil fertility and crop growth (radish; Raphanus sativus). More specifically, the treatment of the composted food wastes enabled a stimulated growth of radish leaves by 80% and an increased uptake of δ15NAIR by 250% compared with a commercial organic compost. Moreover, the compost derived from the wastes appeared to allow a sustainable management of nitrogen fertilizer compared with the chemical fertilizer, minimizing nitrogen pollution. The microbial community analysis showed significant difference in the microbial community pattern in soil treated with the composted food wastes relative to soil treated with a commercial organic fertilizer or a chemical fertilizer. The results may indicate that the wastes processed by the consortium could result in an efficient recycling of the nuisance materials such as food wastes and other organic solid wastes.
