Self-sufficiency rate of food in South Korea is almost at the lowest level among OECD countries, and the decrease tend of farmland is expected to be continued. In this situation, the government has been revised the target self-sufficiency rate of food, and carried forward various policies in order to achieve it. One of those policies is the restoration business of idle farmland which is planned to carry forward after 2015. This study set up indicators evaluating effective use of idle farmland, and tried to apply in the field before carrying forward restoration business. The result of this study may be summarized as follows. First of all, it reset an evaluation indicator that was based on the evaluation indicator developed in order to set application directions of idle farmland. Next, it selected 30 idle farmlands with reset evaluation indicator among 11,635 which were inspected nationwide in 2012. Before applying indicator, it measured the condition of recycling such as accessibility of farmland, condition of irrigation and drainage system, land state, and surroundings by field investigation. Then, it calculated composite score in each target area through applying indicators, and verified the indicator by comparing calculated result with the one which was decided from field investigation. Finally, it carried out field investigation, correct and upgrade some problems of the standard of score calculation that was found during applying previously set evaluation indicator to target area, and established the final standard of calculation for evaluation indicator.

Traditionally, the persimmon Gojongsi (Diospyros kaki Thunb) is peeled to make dried persimmons and the skins are thrown away. In this study, the quality characteristics of cookies containing persimmon peel powder were tested for recycling of the persimmon peels. The amounts of persimmon peel powder added to the cookies were about 0, 5, 7, 9 and 11%. The densities of the cookies of the control group and the persimmon peel powder containing experimental group were 1.25 and 1.25~1.37 respectively. The pH was 6.02 for the control group and 5.95~6.01 for the experimental group. Significant differences in the moisture content were observed between groups at 3.34 and 2.16~3.31 for the control and experimental groups, respectively (p<0.05). The spreadabilities and loss rates of the cookies increased with increasing amounts of persimmon peel powder (p<0.05). In contrast, the loss rates and leavening rate of the cookies decreased significantly with decreasing amounts of persimmon peel powder (p<0.05). The lightness of the cookies showed significant decrease (p<0.05), while the redness and yellowness increased with increasing amounts of persimmon peel powder. The hardness (kg) of the control group was 0.847 while that of the experimental group was 0.904~1.110. In the QDA, the results of sensory characteristic analysis showed that the experimental group earned 11% higher scores for color, flavor, taste, and bitterness, 7% higher for appearance and 9% higher for after taste. The consumer acceptance test revealed the experimental group to have a 7% more positive evaluation for color, favor, taste and texture than the control group. On the grounds of the experiment above, the optimal mixture ratio from the sensory test was found to be 7% persimmon peel powder in the cookies.

Up-cycling has evolved from its original form of the simple recycling of waste, into an industry of its own that has been gaining momentum. In many developed industries, up-cycling is increasingly seen as an 'environmentally-friendly way of production and ethical way of consumption'. However, an examination of the designs of branded up-cycled products suggests that there is a need for product development fueled by further research on materials. The purpose of this study is to introduce various production methods that can overcome the shortcomings of using waste material and Korean motifs for use in product development, which ultimately contribute to enhancing the potential variety and character of up-cycled products. In order to do so, the up-cycling industry was examined to define key concepts, domestic and overseas markets were surveyed, and case analyses were conducted on domestic and foreign up-cycling brands. In addition, after tracking how leather is discarded and accumulated as waste and then collecting the discarded leather, the properties of the material were analyzed. A study of Korean motifs was followed by the concept summary, and upcycling design expressions that exemplify Korean images were identified. The following two novel methods were used to create six up-cycled bags using collected discarded leather. First, lucky bags and moon pots were selected from various Korean motifs in order to use motifs with identifiable features. Secondly, different variations of cutting and attachment methods were used, including iron mold production methods and presses.

This study examines a business survey on the utilization of fishery by-products with the aim to assess the feasibility of incorporating these by-products into various industries. The research involved surveying 312 biocompanies across the country and conducting an empirical analysis based on the collected data. South Korea, a leading seafood-producing country with a developed seafood processing industry, provides conditions necessary to utilize seafood by-products as raw materials for the marine bioindustry. Among the surveyed biocompanies, 38.5% expressed their intention to engage in industrial activities involving the use of fishery by-products in the future, indicating a significant level of interest within the bioindustry in utilizing marine and fishery by-products. Companies showed interest in diverse materials, such as scales, fish bones, skin, and kelp holdfast beyond those currently defined under the Fisheries By-products Recycling Promotion Act (officially unnamed, 2021). This suggests a need for improvements in the regulatory framework to accommodate these diverse biomaterials. Furthermore, we propose enhancing the efficiency of fishery by-product utilization by focusing on regional specialization in marine bioindustry. This involves utilizing existing legal framework for upcycling fishery by-products and fostering a regionally specialized marine bioindustry.

Christopher Nemeth is a designer who combines characteristics of a pioneering upcycle design and deconstructionist design with fabrics, waste clothing, and pieces of fabric recycled in the 1980s. By hommaging his work from the Louis Vuitton 2015 F/W collection, Kim Jones is once again becoming a source of design inspiration in an era where upcycling fashion is attracting attention. Accordingly, an upcycling design approach might appeal to the MZ generation. Christopher Nemes' design presented in this study as a representative fashion designer of dismantling upcycling is basically based on dismantling. It can also be interpreted as dismantling upcycling design because it uses used clothing, waste clothing, and discarded fabrics as materials. This study examined main techniques of upcycling fashion design and derived characteristics of Nemes design as "deconstructive techniques using free lines of construction," "recycling upcycling vintage materials and clothing accessories," and "using handcrafted techniques of artistic sensibility." By applying Nemes' dismantling upcycling technique, four designs were developed for men's top and bottom sets for targets in their 20s and 30s to suggest the commercialization possibility. This study is meaningful in that it proposes a methodical alternative to the new deconstructionist upcycling design that can show Nemes' aesthetic characteristics, creative perspective, and personality by modernly reinterpreting the deconstructionist upcycling technique extracted through analysis of fashion designer Christopher Nemes' design. In particular, by actually producing the work and confirming whether the design technique can be implemented, the value as a fashion product that can be sold is realized.

Lowly volatile heterocyclic sulfur compounds generated in autoclaved garlic extract were isolated and identified, and their antimicrobial activity was determined. Two kinds of unusual volatile sulfur compounds were separated from heated garlic by preparative recycling high performance liquid chromatography (HPLC), and identified by gas chromatography (GC)-mass spectrometry (MS) and $^1H$-nuclear magnetic resonance (NMR). They had heterocyclic structures with 4 to 5 sulfur atoms in the molecules. 4-Methyl-1,2,3-trithiolane (MTTT) is highly volatile and was not able to be concentrated, and was identified by GCMS only. MTTT and 6-methyl-1,2,3,4,5-pentathiepane (MPTP) are lowly volatile and were obtained in pure states to be positively identified for the first time. All 3 heterocyclic sulfur compounds began to appear by the time when the early-formed diallyl sulfides started to disappear. The minimum inhibitory concentration range of MTTT and MPTP was determined to be between 1 and 6 ppm against all yeasts tested. MTTT and MPTP were lowly volatile and sparingly soluble in water.

The scale of repair parts market reached 0.1 billion won. Above all, it is remarkable that the automotive insurance business world is paying f3r 40 ~5o% of the whole repair cost. The repair parts consist of a genuine parts, non-genuine parts, recycling used parts. It is the recent trend that recycled parts are more popular than the genuine parts f3r repairing crashed cars due to the cost. Performance of recycled continuous velocity(CV) joints and power steering(PS) gear box as replacement parts was tested and analysed in this study. To examine the durability of the recycled parts, the replaced CV joints and PS gear box after repair were tested and analysed periodically. The results were showed that basic performance of the recycled parts was normal. However the ball cage of CV joints was more frequently damaged than genuine parts. We concluded that a test standard and amendment of related laws for recycled parts is required to get a safe and durable parts.
