The extent of biological diversity being revealed by molecular techniques accentuates the need to develop methods to isolate and culture the large numbers of microorganisms that remain to be studied. The discovery and characterization of novel microorganisms will provide information useful in understanding microbial ecosystems and have the potential to lead to new products for the biotechnology industry. In this review, the use of innovative techniques and exploration of unusual ecosystems, that have begun to address the challenge of isolating the "uncultured" members of the microbial population, are examined.

This paper provides a new theoretical rationale for public procurement for innovation (PPI), a unique policy encouraging public procurers to purchase innovative products. In contrast to existing studies that primarily emphasize the advantages of PPI, this paper takes a comprehensive approach, examining both the costs and risks associated with PPI, alongside its benefits. It finds a general condition under which PPI outperforms traditional public procurement. Under this condition, this paper demonstrates that PPI enhances social welfare by facilitating optimal risk-sharing between public procurers and the general economy. Additionally, it draws policy implications from a comparative analysis between the current PPI policy in Korea and an optimal PPI policy.

Sustainability in fashion cannot ignore fashion attributes required for the design of rapidly changing and innovative products. This study examines "Re-Birth Design" development and provides a means to apply academic and industry perspectives to the investigation of Re-Birth fashion product development. This study defines "Re-Birth Design" as stock that has been designed and launched through distribution channels, subsequently returned unused, then improved and reborn into a new product for redistribution. This study analyzed specific cases. We selected 100 designs for Re-Birth from 11 brands of "K" fashion company in Korea, to be successfully sold in 2014. These cases are used in the analysis and are categorized into design types. As a result of the analysis, "Re-Birth Design" had five levels: Level 1. Changes in supplementary materials such as adding or removing decoration, Level 2. Changes in patterns or materials (changes within the product), Level 3. Partial changes in design (leading to a new design), Level 4. Complete deconstruction and rebirth of the design, and Level 5. Complete deconstruction followed by the use of the design source for a new product that is not a garment. This study analyzed products owned by brands, as well as successful cases of Re-Birth designs that reused existing resources, reduced energy consumption, and increased environmental and economic efficiency by recreating new products that could be resold.

Intense pulsed light(IPL) has been highlighted as an innovative nonthermal sterilization technology that can kill spoilage or pathogenic microorganisms by using short-duration pulses of intense broad-spectrum electromagnetic radiation. This paper examines the inactivation effects of IPL on Listeria monocytogenes, Escherichia coli O157:H7, and Pseudomonas aeruginosa inoculated on seafood products such as salmon, flatfish, and shrimps and evaluates the possibility of extending the shelf-life of seafood products. The results indicate that the inactivation of microorganisms increased with an increase in IPL energy density($J/cm^2$) and a decrease in the distance between the sample surface and the lamp. In addition, temperature increases on the fish fillets during the treatments were well controlled within the range of 5.7~$9.8^{\circ}C$. The IPL treatment had a significant positive effect on the storage stability of seafood products at the storage temperature of $4^{\circ}C$ for 12 days. These results suggest that the storage period for fish fillets can be extended from 4 days to 6~8 days through the IPL treatment.

Natural products are a rich source of biologically active small molecules and a fertile area for lead discovery of new drugs [10, 52]. For instance, 5% of the 1,031 new chemical entities approved as drugs by the US Food and Drug Administration (FDA) were natural products between 1981 and 2002, and another 23% were natural product-derived molecules [53]. These molecules have evolved through millions of years of natural selection to interact with biomolecules in the cells or organisms and offer unrivaled chemical and structural diversity [14, 37]. Nonetheless, a large percentage of nature remains unexplored, in particular, in the marine and microbial environments. Therefore, natural products are still major valuable sources of innovative therapeutic agents for human diseases. However, even when a natural product is found to exhibit biological activity, the cellular target and mode of action of the compound are mostly mysterious. This is also true of many natural products that are currently under clinical trials or have already been approved as clinical drugs [11]. The lack of information on a definitive cellular target for a biologically active natural product prevents the rational design and development of more potent therapeutics. Therefore, there is a great need for new techniques to expedite the rapid identification and validation of cellular targets for biologically active natural products. Chemical genomics is a new integrated research engine toward functional studies of genome and drug discovery [40, 69]. The identification and validation of cellular receptors of biologically active small molecules is one of the key goals of the discipline. This eventually facilitates subsequent rational drug design, and provides valuable information on the receptors in cellular processes. Indeed, several biologically crucial proteins have already been identified as targets for natural products using chemical genomics approach (Table 1). Herein, the representative case studies of chemical genomics using natural products derived from microbes, marine sources, and plants will be introduced.

본 연구는 우리나라 사회혁신기업이 일반기업과 경쟁에서 차별화된 경쟁력을 갖추고 경쟁우위를 확보할 수 있도록 소비자들의 사회혁신기업에 대한 브랜드 태도에 초점을 두고 연구를 진행하였다. 이를 위하여 사회혁신기업의 제품과 일반기업의 제품에 대한 소비자의 브랜드 태도의 차이를 블라인드 테스트를 통하여 비교하였다. 본 연구의 블라인드 테스트 결과 사전 블라인드 테스트에서는 제품속성이나 브랜드 태도에 있어서 통계적으로 유의한 차이가 없는 것으로 나타났으나 사후 제품의 정보를 공개한 후에는 실험물로 사용된 비누 제품이 천연 수제 비누라는 정보가 포함되어 있어 사회혁신기업과 일반기업 제품 모두에서 사후 브랜드 태도가 향상됨을 보여주었다. 그리고 사회혁신기업이 추구하는 사회적 가치에 대한 설명을 해 준 후에는 일반기업에 비하여 사회혁신기업에 대한 관심 증가로 인해 사회혁신기업 제품에 대한 브랜드 태도가 통계적으로 유의하게 높게 나타나는 결과를 보였다. 제품 포장에 명확하고 과장되지 않은 정보표시는 브랜드 태도를 향상시킬 수 있는 도구가 될 수 있다는 것이다. 또한 사회혁신기업 제품에 대한 소비자들의 인식을 높이기 위하여 정부 차원에서의 사회혁신기업에 대한 교육과 홍보 정책이 제고되어져야 할 필요가 있을 것이며, 사회혁신기업이 자신들이 추구하는 사회적 가치에 대한 내용을 제품 포장에 광고카피로 표현함으로써 스스로를 홍보하는 자구책을 마련하는 것도 브랜드 태도 향상을 꾀하고 판매증가를 위한 또 하나의 돌파구가 될 수 있을 것이다.

Single households currently account for 26.5% of all households and their number is expected to continue to rise, reaching 34.5% by 2035. An analysis of the consumption trends and needs of single households shows that they are rising as a new consumer group with a focus on investment on the individual and favouring: small but high-tech products: efficient use of limited resources: safety and peace of mind: self-improvement and leisure. Products which meet such demands are having an impact on the growth of home-furnishing market. An analysis of companies in Korea's home-furnishing market, with examples like the lifestyle company IKEA, shows a variety of brands such as SPA brand, furniture specialist, distributor and character products. And yet most are OEM products which lack differentiated product lines and compete with similar display and distribution structure. We needs the Single household consumption tendency of home-furnishing market and differentiation strategy through product analysis. In order to increase the value of companies in the home-furnishing market, in addition to differentiated design, product competitiveness must aspire to higher customer satisfaction with easy assembly, innovation in logistics, innovative sales methods such as virtual-reality simulation for products and space, individually-tailored furniture for the needs of single household and products which combine smart technology. For home-grown home-furnishing brands to have competitiveness, they must leverage on the strengths of the industry, offering differentiated and competitive products in a wider range of areas with convergence functions as well as differentiation in consumer interface and application of advancing technology; in-depth product research is called for.

Recently, the textile and fashion industry has adopted 3D printing technology, through which filaments are accumulated continuously in the form of sections to produce digitalized three-dimensional fashion products. Little research has been done regarding the consumer perspectives on 3D printed fashion product. Therefore, the purpose of this study was to investigate the effects of consumer innovativeness, uniqueness, and perception factors on consumer attitudes and purchasing intentions for 3D printed fashion products. A questionnaire was given to consumers living in Seoul and Kyunggi, South Korea. The data obtained from the 159 completed questionnaires was analyzed by regression analysis, factor analysis, and Cronbach's alpha using SPSS 24.0. The results were as follows: First, consumer innovativeness and uniqueness, in descending order, positively affect the perceived social image. Consumer innovativeness positively affects perceived aesthetics and consumer uniqueness positively affects perceived novelty. Second, social image has a positive effect on consumer attitudes to 3D printed fashion products. Third, consumer attitude positively affects purchasing intentions towards 3D printed fashion products. Fourth, consumer innovativeness and uniqueness, in descending order, have a positive effect on consumer attitudes and purchasing intentions for 3D printed fashion products. Fifth, social image and novelty, in descending order, positively affect purchase intentions for 3D printed fashion products. Therefore fashion firms should develop their marketing strategy to focus on innovative, unique consumers as a main target and aim to enhance buyers' social image by using 3D printed fashion products.

This study investigates the influence of the innovativeness of consumers on extended products in brand extensions. 300 surveys were distributed and 283 were used in the final analysis. The results of this study show that consumers evaluate similar product category (i.e., sportswear) better than a dissimilar category (i.e., cosmetics) in brand extension. In addition, innovative consumers evaluated extended product better regardless of similarity with the original brand. The results showed that consumers with higher level of innovativeness were less likely to evaluate differently between a similar product and dissimilar product categories in apparel brand extension.
