Green economy, also known as sustainable economy, is a current development trend in which consumers prefer products that are wholly or partly derived from materials of biological origin since they have become more concerned about their health and the environment in which they live. This study aims to examine consumer behavior toward bio-based products with three key goals in mind. First, it helps to understand the perception of consumers toward Bio-based products. Second, it properly helps consumers be aware of products derived from materials of biological origin so that the consumer can make purchasing decisions to protect their health and contribute to the protection of the environment. Third, the study on consumer behavior towards bio-based products will provide a more accurate view and assessment to companies looking to develop Bio-based products. Based on that, the research is carried out through surveying, collecting data from consumers, and then using the deductive approach, descriptive statistics, and quantitative method analysis. The results demonstrated that a positive relationship and a direct impact are established between the variables of Attitude and Social Norms and the Purchase Intention toward Bio-based products. Furthermore, the findings reveal that customers have positive feelings towards bio-based products in terms of trust, knowledge, and the environment.

The purpose of the study was to determine a method to use fresh white Korean ginseng in the form of higher intake of medicinal components. Decoction was made at $70^{\circ}C$ and $90^{\circ}C$ in different intervals of time. HPLC (DAD) system was employed to monitor the ginsenosides content in the decoctions and the components were identified by comparing the retention time with that of reference compounds. However, decoction made at $70^{\circ}C$ in 72 hrs possessed higher amount of total ginsenosides ($209.6{\mu}g/mL$) content where considerable amount of bioactive ginsenosides like Rg3, Rb2, Rb1 and Rg1 were accumulated. Overall, it can be concluded that the fresh white Korean ginseng decoction made in 72 hrs at $70^{\circ}C$ would be useful for the health and other medicinal approach of ginseng.

Recently, there has been a rapid increase of interest in u-Health systems or instruments. The importance of testbeds has been discussed deeply also. However, beyond laboratory or ward environments, testbeds covering metropolitan area cannot be found easily. Moreover, there has been few papers which discuss the results of testbed operations for various instruments in different age groups. In this paper, the results of testbed which operated in Daegu metropolitan area are discussed and improvement directions to strengthen the competitiveness are proposed using user analysis. In particular, the results of trial services using the u-Life support instruments (medication reminder, falling safety phone, bio-patch and shirts, etc) for super aging societies in the near future are discussed.

The primary objective of this research is to utilize machine learning models to analyze factors tailored to each dataset for predicting mental health conditions. The study aims to develop appropriate models based on specific datasets, with the goal of accurately predicting mental health states through the analysis of distinct factors present in each dataset. This approach seeks to design more effective strategies for the prevention and intervention of depression, enhancing the quality of mental health services by providing personalized services tailored to individual circumstances. Overall, the research endeavors to advance the development of personalized mental health prediction models through data-driven factor analysis, contributing to the improvement of mental health services on an individualized basis.

Hydrate minerals are contain H$_2$O to offer a place for our health and life of living organism. I wish to present a hypothesis to explain the mechanism on which every living organism survives, gets sick and recovers again Hydrate minerals are the very prerequisite for all animals and the welfare of mankinds. Hydrate minerals are used to the main medical stuffs, the meterials for water purification and porous meterials for bio-ceramic and bio-plastic industries

Biosorption of lead by marine algae, Undaria pinnatifida, was examined. The biosorption capacity of lead by U. pinnatifida was above 30% of its own weight and proportional to the initial lead concentration. However, the opposite result was shown in different initial weight of biomass. The mechanism of biosorption was accorded to the ion exchange process.

본 연구는 국외 바이오산업 클러스터의 태동 과정과 경쟁력 결정요인을 살펴보았다. 바이오산업은 다양한 산업에 접목할 수 있으며, 인공지능과 정보통신기술 등과 결합한 고부가가치 창출이 가능한 까닭에 세계 주요국에서 주목하는 유망 신산업이다. 또한, 기업, 대학, 병원, 연구기관, 정부 등 여러 이해관계자와 연계·협력이 필요하다는 점에서 클러스터의 중요성이 강조된다. 그러나 이 같은 중요성과 관심에 비해 국내의 관련 연구는 다소 미흡한 편이다. 특히, 국외 사례 연구도 소수의 선도 클러스터에 지나치게 치우쳐 있어, 국내 지역 실정에 부합하지 않는 정책과 발전 방안을 내놓는 경향이 있다. 이 같은 문제를 완화하고자, 본 연구는 미국의 바이오 헬스 캐피털 리전, 영국의 케임브리지 클러스터, 덴마크와 스웨덴의 메디콘밸리 세 곳의 태동 및 성장 과정을 살펴보았다. 이를 통해, 부족했던 관련 사례 연구를 풍부하게 하고, 각 클러스터의 경쟁력 결정요인을 파악하여 국내 바이오산업 클러스터의 조성과 육성에 대한 시사점을 제시하고자 한다.

VBNC(Viable but nonculturable)란 생존에 불리한 환경하에서 살아 있으나 일반 영양배지에서 자라지 못하는 미생물의 상태를 나타낸다. 본 연구는 구리를 이용해 Escherichia coli에서 VBNC를 유도하고 이의 특성을 살펴보았다. 구리를 처리한 후 전통적인 평판 배양법에 의한 집락 형성계수(colony forming unit, CFU)를 측정한 결과 배양되지는 않으나, Live/Dead BacLight bacterial viability kit 염색 후 유세포계수기로 측정한 결과 살아있는 미생물로 계수되어 VBNC 상태가 확인하였다. VBNC 유도된 미생물로부터 genomic DNA와 RNA를 분리하고 이들의 안정성을 관찰하였는데 DNA에 비해 RNA의 붕괴가 많이 진행되었음을 확인할 수 있었고 RNA의 붕괴는 특정크기로 붕괴되는 것으로 관찰되었다. 또한 생물전용 투과전자현미경(Bio-Transmission Electron Microscope, Bio-TEM)을 통해 VBNC 세포의 형태를 관찰하였는데 VBNC 상태에서는 정상상태에 비해 periplasmic space가 온전하지 못하고 세포내막과 세포 외막이 분리되었으며 세포질의 양이 현저히 감소됨이 관찰되었다.
