4차 산업혁명의 바람이 불어오고 있는 지금, 합성생물학 분야는 표준 기술 개발을 통해 '디지털 생물제조업'이라는 새로운 제조업으로의 성장이 기대되고 있다. 나아가 생물학적 부품의 구조 및 기능, 생물 정보 등과 관련하여 다양한 합성생물학의 표준이 제안되고 있기에 신속한 대응이 필요하다. 이에 합성생물학을 둘러싼 지적재산권, 규제에 대한 검토를 통해서 기술발전을 저해 촉진하고 있는 요소들을 도출하고자 한다.

In this paper, we proposed and modeled a video contents protection system based on the infectious information hiding(IIH) technique as using characteristics of biological viruses. Our proposed IIH System considered the requisite important information for video contents protection as the infectious virus, and suggested a new paradigm about video contents protection that transmitted infectious information from contents(host) or video CODECs(viral vector). Also, we modeled the Pathogen, Mutant and Contagion virus as the infectious information and defined technical tools about verification of infectious information, kernel based IIH, contents based IIH and creation/regeneration of infectious information as main techniques for our IIH system. Finally, through simulations that carried the infectious information by using conventional information hiding algorithms as kernel based and contents based IIH techniques, we verified possibilities of our proposed IIH system.

Chlorinated aromatic compounds are one of the largest groups of environmental pollutants as a result of world-wide distribution by using them as herbicides, insecticides, fungicides, solvents, hydraulic and heat transfer fluids, plasticizers, and intermediates for chemical synthesis. Because of their toxicity, persistence, and bioaccumulation, the compounds contaminated ubiquitously in the biosphere has attracted public concerns in terms of serious influences to wild lives and a human being, such as carcinogenicity, mutagenicity, and disturbance in endocrine systems. The biological recalcitrance of the compounds is caused by the number, type, and position of the chlorine substituents as well as by their aromatic structures. In general, the carbon-halogen bonds increase the recalcitrance by increasing electronegativity of the substituent, so that the dechlorination of the compounds is focused as an important mechanism for biodegradation of chlorinated aromatics, along with the cleavage of aromatic rings. The removal of the chlorine substituents has been known as a key step for degradation of chlorinated aromatic compounds under aerobic condition. This can occur as an initial step via oxygenolytic, reductive, and hydrolytic mechanisms. The studies on the biochemistry and genetics about microbial dechlorination give us the potential informations for microbial degradation of xenobiotics contaminated in natural microcosms. Such investigations might provide biotechnological approaches to solve the environmental contamination, such as designing effective bioremediation systems using genetically engineered microorganisms.

Landfarming and a microbial agent were used to treat dilsel-contaminated soil. The microbial agent was applied to the contaminated soil in a concentration of 5$\times$102 cfu/soil(g) and the total amount of microbial agent, 210 l , was sprinkled on the soil four times for 24 days during 50 day-remediation period. The remediation goal, lower than 800mg/kg of TPH, was achieved from 5,707mg/kg of TPH within 50 days. The total number and activity of indigenous microorganisms were increased by 100 times after the microbial agent, Bioil-D, was applied to the contaminated soil.

자연계의 물은 오염물질이 유입되었을 때 그 스스로가 유입된 오염물질을 물리적, 화학적, 생물학적 작용을 통해 원상태로 회복할 수 있는 자정 능력을 가지고 있다. 수질관리정책의 핵심은 이런 자정능력이 유지될 수 있는 범위 내로 오염물질이 유입되도록 하는 것이며 그 수단이 오염물질 관리 및 규제제도이다.

지금까지 인간이나 다른 생물체의 전체 유전체 염기서열을 밝혀내는 작업은 크게 세가지 방법으로 진행되었다. Clone-by-clone approach, sequence tagged connector approach, random shotgun approach[1]가 그것인데 마지막의 random shotgun approach는 fragment assembly problem을 비롯한 여러 가지 전산학적인 문제들을 수반한다. 미생물체의 전체 염기서열을 random shotgun approach를 이용하여 밝혀낼 때 몇 가지 전산학적인 문제가 테크닉이 필요하며 그 중에서도 서열간의 forward, reverse의 mating 정보를 이용하는 것이 중요하다. 본 논문은 이러한 mating 작업을 한 눈에 볼 수 있게 하는 소프트웨어 페키지 “Mater”에 대해 소개하고자 하며 그 의미에 대해 논하고자 한다.

From the biopsychological point of view,learning could be defined as the processes to transfer the information that we obtain from environment to the neural circuits in the brain.In the studies to determine the biological substrates of learning and memory,there was a remarkable effort to identify neural circuits related with a specific type of learning and to describe the mechanixm of neural plasticity of learning and memory,under the assumption that the memory orinformation may be stored as a modificationof neural synapes in the central nerviys system.On the other hand,there was a different kind of tendency to analyze the mechanism of interactions between neural substrates involved in learning and memory,under the assumption that a specific information may be represented in the patterns of comples neural network of the central nervous system.The present review,in the former position.focused on the research methods and the chracteristics and finding of the investigations employing animal model systems to indentify the essential site of engram for learning and memory.Specifically,the review presents major advances in ourunderstanding of the memory trace circuit for a specific type of learning,with the use of animal model system,the detemination of the critical lodi of neuaral plastic chabges In learing abd memory,and the neurophysiological an biocemical mechanixms of the neural modifia by learint.

생물정보학 분야에서의 온톨로지는 다양한 생물학적 의미들을 표현하는 구조로 되어 있으며, 생물학 데이터의 의미를 효과적으로 해석할 수 있는 매우 중요한 기술로 인식되고 있다. 특히 바이오 온톨로지는 생물학 데이터베이스로부터 정보에 대한 탐색과 추론 등 의미 전달 과정에서 중심적인 역할을 수행한다. 본 논문에서는 단백질 구조 예측을 지원하는 다중 에이전트시스템인 APSS내에서 각 구성원 에이전트들간에 온톨로지에 기초한 정확한 구조 정보의 전달을 통해 효과적인 단백질 구조 예측 작업을 지원하고자 한다. 이를 위하여 먼저 단백질 구조 관련 바이오 온톨로지의 설계방법을 제시하고, 이것에 기초한 실제 바이오 온톨로지의 설계에 대해 설명한다. 그리고 이렇게 구축된 단백질 구조 온톨로지를 APSS시스템 안에서 어떻게 응용하였는가에 대해서도 설명한다.

EMF (Electromagnetic Field) is a valuable resource for living in a knowledge-based information society. The EMF is used in home appliances that make our lives easy and convenient, and in telecommunication devices such as mobile phones, personal computers, medical devices and broadcasting towers. However, the biological hazards associated with EMF exposure are also increasing in signal from telecommunication devices. Studies of the effects of EMF exposure on humans have been conducted for a long time, but it has not yet been demonstrated whether the EMF effect is harmful. In this paper, we examine the electromagnetic field emitted from various electronic devices around living and its effect.
