  • 최근 전분당업계에서 전분당의 원료로 그동안 수입하던 일반 옥수수 대신 유전자 재조합 옥수수를 수입하면서 유전자 재조합 식품에 대한 논란이 다시 가열되고 있다. 1996년 유전자 재조합 콩이 처음 상업적으로 재배된 지 10년이 지났지만 유전자 재조합 식품에 대한 논란은 아직도 계속되고 있다. 이런 상황에서 우리나라에서는 유전자 재조합 식품을 어떻게 관리하는지 살펴본다면 유전자재조합 식품을 이해하는데 많은 도움이 될 것이다.

The RNA Base Over 95% of Onju Citrus and Coffee Genes Cut & Paste Based on The BCJM Matrix with Chargaff-Shannon Entropy (BCJM 행렬 및 Chargaff 법칙과 Shannon Entropy에 의한 RNA 유전자 비율이 95%이상인 온주감귤과 귤의 유전자 조합)

  • The heterogeneous Onju citrus genes (A=20.57, C=32.71, G=30.01, U=16.71%) and coffee genes (A=20.66, C=31.76, G=30.187, U=16.71%) have the same genetic ratio of 95% or more. It is known that gene compatibility is generally not possible with this group. However, it can be grafted if the conditions of Chargaff rule and Shannon Entropy are met with gene functional-similarity of more than 95%, and it becomes a new breed of Coffrange. We calculated the world's first BCJM matrix for DNA-RNA and published it in US patents and international journals. All animals and viruses are similar to human genes. Based on this, it was announced in June in the British matrix textbook by solving the genetic characteristics of COVID-19 and the human body. In plants, it is treated with BCJM-Transposon treatment, a technique that easily changes gene location. Simulation predicted that the matrix could be successful with Cut & Paste and Transpose.

  • Genetic algorithm was first introduced to study adaption phenomena occurring in nature based on Darwin's theory of survival of the fittest. It has been used when analytical approach is not possible because of a large number of variables. In this paper, we demonstrated that genetic algorithm could be used to obtain physically optimized experimental values. We programmed a genetic algorithm that uses a few Gaussian functions to find a given function value and the same algorithm was connected to the laser system to obtain laser pulses of 40fs of maximum pulse width and 1mJ of maximum output power. This study shows that genetic algorithm can be applied to laser systems to obtain the optimized laser pulses.

  • The Geonjae Old House Garden of Asan Oeam Village contains historical and academic values as a major element of the village's landscape, along with the village's feng shui geographical conditions and artificial roads that pass through the village, which represent the village. Although some have been maintained over a long period of time, many of them have been lost, disturbed, and distorted. The main houses of Oeam Village had traditional gardens, but the garden of the Geonjae Old House is a place where different garden cultures coexist in one place due to the creation of Japanese-style gardens in Japanese colonial era. This study predicts the past through genetic analysis of the garden of the Geonjae Old House, and establishes a restoration plan for the garden of the Geonjae Old House through historical restoration of the results. In addition, the purpose of this study is to suggest a way to avoid damage in restoring the original form of cultural properties as much as possible and to facilitate the preservation and management of cultural properties. As a result of contrast with past photographs and on-site evidence, it was found that the garden of the Geonjae Old House has a different shape from its previous appearance due to repeated distortion and damage. In addition, it was possible to suggest a restoration method that could reproduce the appearance of the past through genetic analysis.

  • Today's scientists try to remove heavy metals with many new technologies such as phytoremediation. One of the best cutting edge technologies is developing transgenic plants to remove certain heavy metal in soil. I constructed the transformation vector expressing T. goesingense Metal Transport Protein1 gene and TgMTP1: GFP genes. The transgenic plants were selected and confirmed the transformed genes into Arabidopsis thaliana genome. Expression was confirmed in several parts in Arabidopsis cells, tissues and organs. When TgMTP1 overexpressing Arabidopsis thaliana were subjected, transgenic plants showed higher heavy metal tolerance than non-transgenic. For further study I selected the transgenic plant lines with enhanced tolerance against four different heavy metals; Zn, Ni, Co, Cd. The accumulation of these metals in these plants was further analyzed. The TgMTP1 overexpressing Arabidopsis thaliana plant of selected lines are resistant against heavy metals. This plant is characterized by the expression of the MTP1 gene accumulating heavy metal in the vacuole and being simultaneously expressed on the plasma membrane. In conclusion, these plants may be used in plant purification applications, and as a plant with increased tolerance.

  • Collaborative filtering technique is a major method of recommender systems and has been successfully implemented and serviced in real commercial online systems. However, this technique has several inherent drawbacks, such as data sparsity, cold-start, and scalability problem. Clustering-based collaborative filtering has been studied in order to handle scalability problem. This study suggests a collaborative filtering system which utilizes genetic algorithms to improve shortcomings of K-means algorithm, one of the widely used clustering techniques. Moreover, different from the previous studies that have targeted for optimized clustering results, the proposed method targets the optimization of performance of the collaborative filtering system using the clustering results, which practically can enhance the system performance.

  • There are some methods such as fatty acid analysis and microscope analysis of parasite egg and pollen and genetic analysis of ancient bacteria from ancient soil. The fatty acid analysis can examine whether some materials is human feces or animals. This is important thing to reconstruct ancient toilet culture pattern. The methods using TLC and GC-MS as organic chemistry is able to confirm ancient diet life style and nutritive conditions. The microscope analysis of ancient soil is able to confirm ancient parasite egg and pollen. It is possible to analogize ancient human diseases from this analysis. Also, genetic analysis is able to confirm genetic diversity and variation pattern of ancient organisms in archeological soil. Most of all, it is convinced of carrying through genetic preservation of exterminated ancient organisms. If archeological soils should be analysed through the natural scientific methods such as organic chemistry, soil science, microbiology, molecular biology, and genetics, this is helpful for us to understand and interpretation past historic event. And it is expected to perform an major role for understanding origin of ancient human and life style.
