  • The purpose of this study is to develop and implement a step-by-step upcycling fashion education program that can be utilized within the local community. This program aims to provide basic data by analyzing the current state of community-based upcycling projects and upcycling center programs. To achieve this, the study first examined the meaning and value of upcycling in fashion through literature research and explored upcycling projects and programs in connection with local communities. Subsequently, an upcycling fashion education program platform was developed and applied using the design thinking process. The program involved students from nine high schools in Gwangju Metropolitan City. Depending on the school's circumstances, the time and difficulty level of the upcycling education program were adjusted accordingly. A unique eco-bag making kit, using jeans developed in this study, was employed. Following the completion of the program, a satisfaction survey was conducted among 167 participating students from the high school community class. The findings indicated that the majority of students experienced an increased appreciation, attraction, and interest in upcycling products. They also demonstrated an understanding of the environmental impact of upcycling products and the distinction between upcycling and recycling. It is believed that the educational program developed in this study can promote ethical fashion and foster a sense of value-based consumption. This program can be customized and flexibly adapted to different educational levels and institutional characteristics, making it accessible to a wide range of learners.

  • Recently, Korea's interest in environment protection is increasingly growing, and Korea realizes the seriousness of environmental pollution and national movement to minimize the effect is arising. As part of the movement, the need of environmental education in elementary schools is on the rise. This study aims to develop integrated environmental experience programs allowing students to have experience activities in forests, rivers, and seas that they can approach easily around them and to have environmental education through various plays. In addition, the study purposes to compare general educational education programs in actual education in terms of the effect of the program on students' environment attitudes. This study was conducted to 50 fourth graders in two classes of S elementary school in Busan, and the 25-student comparative group had the normal educational education program that is mostly being performed in actual education while the 25-student treatment group had the survey on environmental attitude after a class using an integrated environmental experience program. The survey content is about environmental attitudes, and it consists of six subjects such as general environment, environmental pollution, energy, water resources, recycling, and animal protection and has 7 or 8 items by each subject which is divided into eight sub-items including sensibility, belief, values, spontaneity, criticism, patience, attention and interest. The findings are as follows. First, the integrated environmental experience program has a more positive effect on environmental attitudes than the general educational program. In particular, it is really effective about the topic of animal protection among students' environmental attitudes. Second, the integrated environmental experience program has a more positive effect on values and interests than the general environmental education program.

  • Sustainability has been a important issue in fashion industry that reflects the modern phase of the time. More education institutions than ever before are beginning to offer specialized courses, certificates and degrees related to sustainability in fashion, and many fashion institutions are working to embed sustainability issues into the educational contents. In this study, I investigate how sustainability is being integrated into the curriculum of leading fashion institutions, corporate management activity across the world and overview the world leading educational programmes related to sustainable fashion, pulling out the unique expertise and areas of specialization for each institution. In conclusion, the sustainable fashion were still not widely promoted domestical fashion institutions compare with other foreign leading fashion institutions. This happens in fashion business as well. Korean fashion institutions have to make educational program and certificates and degrees related to sustainability because the educational program can transform domestic fashion industry to sustainable fashion leading country level.

  • Presence of old newspapers printed with waterbased flexographic inks leads to a significant loss of brightness of the deinked pulp by flotation process. It has been shown that neutral or acidic flotation deinking has many advantages in recycling of flexo printed newsprints. A comparative experimental study was performed to evaluate the deinking efficiency of three alcohol type deinking agents in flotation deinking of flexo printed newspapers. Zeta potential of neutral deinked pulp was less negative than alkaline deinked pulp. Also neutral deinking was advantages in reducing turbidity, COD, and cationic de-mands of deinking process water.

  • One Helicosporium strain, isolated from a wilted chestnut tree, evidenced in vitro antimicrobial activity against various types of bacteria and fungi, and generated a diffusible pigment. The antimicrobial compounds and the diffusible pigment of the Helicosporium sp. isolate were purified via solvent fractionation, column chromatography, and recycling preparative chromatography. Both the major antimicrobial compound and the diffusible pigment were identified as 2-methylresorcinol via nuclear magnetic resonance spectroscopy. Therefore, 2-methylresorcinol, a diffusible pigment generated by Helicosporium sp., appears to be an active antimicrobial principle. This pigment also exhibited considerable cytotoxicity against mammalian cells.

  • Recent evidence from genetics, animal model systems and biochemical studies suggests that defects in membrane trafficking play an important part in the pathophysiology of Parkinson's disease (PD). Mutations in leucine-rich repeat kinase 2 (LRRK2) constitute the most frequent genetic cause of both familial and sporadic PD, and LRRK2 has been suggested as a druggable target for PD. Although the precise physiological function of LRRK2 remains largely unknown, mounting evidence suggests that LRRK2 controls membrane trafficking by interacting with key regulators of the endosomal-lysosomal pathway and synaptic recycling. In this review, we discuss the genetic, biochemical and functional links between LRRK2 and membrane trafficking. Understanding the mechanism by which LRRK2 influences such processes may contribute to the development of disease-modifying therapies for PD.
