The effectiveness of genetic markers on Hanwoo traceability systems was applied and evaluated from Korean 33 Hanwoo elite sire families. Five microsatellite markers were selected finally, which were located on chromosomes different chromosomes with the end sequencing of 100 HW-YUBAC that were recorded in the NCBI by Yeungnam University. Eleven major microsatellite markers were selected from allele amplified, their frequencies, H(Heterozygosity) and PIC(Polymorphism information content) with Hardy-Weinberg equilibrium. Next, in order to evaluate the power of the markers selected on the individual animal identification with experimental condition, the match probability(MP) and the relatedness coefficient(R) were computed.

It is argued in this paper that, in determining semantic similarity, Korean words should be recategorized with a focus on the semantic relation to ontology in light of cross-linguistic morphological variations. It is proposed, in particular, that Korean semantic similarity should be measured on three tracks, human judgements track, relatedness track, and cross-part-of-speech relations track. As demonstrated in Yang et al. (2015), GloVe, the unsupervised learning machine on semantic similarity, is applicable to Korean with its performance being compared with human judgement results. Based on this compatability, it was further thought that the model's performance might most likely vary with different kinds of specific relations in different languages. An attempt was made to analyze them in terms of two major Korean-specific categories involved in their lexical and cross-POS-relations. It is concluded that languages must be analyzed by varying methods so that semantic components across languages may allow varying semantic distance in the vector space models.

Genetic relatedness of medically important Exophiala species such as E. dermatitidis, E. mansonii, and three E. jeanselmei varieties: jeanselmei, lecanii-corni, and heteromorpha was examined using PCR-RFLP(restriction fragment length polymorphism) of ribosomal DNA, M-13, $(GTG)_5$ and nucleotide sequences of ribosomal ITS(internal transcribed space) II regions. Three E. jeanselmei varieties showing distinct band patterns for each DNA markers as well as different nucleotide sequences of ribosomal ITS II regions could be considered as a separate species. E. dermatitidis and E. mansonii demonstrated the identical band patterns of RFLP of ribosomal DNA, M-13, and $(GTG)_5$ markers. However, nucleotides sequences of ribosomal ITS II region were different between these two species.

In just-in-time production systems, U-shaped production lines rather than traditional straight lines are often adopted since they have some advantages. The advantages of U-lines over straight lines are that the workstations required can be reduced and the necessary number of workers can be easily adjusted when the demand rates are changed. In this paper, we present a new genetic algorithm(GA) to minimize the number of workstations primarily and improve the work relatedness secondarily in the U-line production systems. Also, a new heuristic method is presented according to the work related factors and characteristics of U-line balancing. Some major aspects of the proposed GA are discussed, with emphasis on representation, decoding and evaluation function. Extensive experiments are carried out on well-known test-bed problems in the literature to verify the performance of our algorithm . The computational results show that our algorithm is a promising alternative to existing heuristics.

A strain of Leptospira interrogans(UM-19) was isolated in 1984 from a patient with epidemic pulmonary hemorrhagic fever. The bacteria has been characterized morphologically by a polymorphism showing spiral forms, short and long rods in culture. In order to study the biological relatedness among these forms of the bacteria, the short rods were separated from others by means of continuous sucrose density gradient centrifugation, and cultured at various temperatures such as $10^{\circ}C$, $15^{\circ}C$, $30^{\circ}C$ and $37^{\circ}C$. It was revealed that cultivation or subcultivation of the short rods has resulted in morphological changes observed by darkfield examination, silver stain, and scanning electron microscope showing spiral forms as well as short and long rods.

Pseudomonas aeruginosa accounts for a significant proportion of nosocomial infections. This study examined the antimicrobial susceptibility pattern and clonal relatedness of P. aeruginosa isolates of clinical and environmental origin. These isolates displayed susceptibility to levofloxacin, ciprofloxacin, gentamicin, imipenem, and ceftazidime of 65.0%, 62.5%, 90.0%, 100%, and 85%, respectively. PCR-RAPD analysis of the P. aeruginosa isolates revealed marked variation. No correlation was observed between the antibiotic resistance profiles and the DNA typing patterns.

최근 인공지능 기술을 이용한 챗봇 서비스가 다양한 플랫폼에 적용되면서 그 이용자의 수도 급증하고 있다. 이에 본 연구에서는 자기결정성이론(Self Determination Theory)을 적용해 이용자의 세 가지 심리욕구(인지된 자율성, 인지된 유능성, 인지된 관계성)가 사용 만족도 및 지속사용의도에 미치는 영향을 살펴보고자 한다. 또한, 챗봇의 타입을 음성 기반 인공지능 비서, 텍스트 기반 모바일 메신저의 두 가지로 구성하고, 챗봇 이용동기는 실용적 동기, 유희적 동기, 사회 및 관계적 동기의 세 가지 차원으로 구성하여 이들간의 관계도 규명하고자 하였다. 본 연구는 챗봇 사용 경험이 있는 이용자들을 대상으로 설문조사 실시하였다. 분석 결과, 자기결정성 요인인 인지된 자율성, 유능성, 관계성이 모두 사용 만족도 및 지속사용의도에 긍정적인 효과를 보였다. 또한 챗봇 이용자의 사용만족도는 지속사용의도에 긍정적인 영향을 미치고 있었다. 또한, 사회 및 관계적 동기가 인지된 자율성과 사용만족도간의 관계를 조절하는 것으로 나타났다. 본 연구는 자기결정성이론을 적용해 이용자 심리적인 특성의 중심으로 이용자 심리욕구가 챗봇 사용 만족도 및 지속사용의도에 어떠한 영향을 미치는지 설명함으로써 다양한 분야의 인공지능 관련 연구의 확장을 도모하고, 급속도로 성장하고 있는 챗봇 시장에 유용한 실무 전략을 제공한다는 점에서 의의가 있다.

이 연구에서는 지역축제가 지역에 미치는 영향에 대한 주민의 지각을 관광관련 여부에 따른 집단 간의 차이를 중심으로 분석하여 사회교환이론의 적응가능성을 확인하고 향후 지속가능한 지역축제 개발을 위한 정책 및 마케팅의 기초자료를 제공하고자 한다. 금산 인삼축제의 개최에 대한 관광산업관련 여부에 따른 지역주민의 지각차이 검증 결과 관광산업 관련 집단의 긍정적 축제영향은 보다 긍정적으로 지각하고 부정적 축제영향은 덜 부정적으로 지각하는 것으로 밝혀졌는데 이는 사회교환이론의 관점에서 사회적 비용보다 편익이 더 많은 것으로 지각하는 것이라고 할 수 있으며, 또한 소위 부담 보다는 보수가 더 높은 것으로 지각한 결과라고 할 수 있다. 따라서 지역축제 개최시 관광산업 관련 여부에 따른 지역주민의 지각차이를 감안하여 차별화된 지역 사회의 관심과 협력을 각각 별도로 수용하여 축제의 기획과 관리에 반영할 필요가 있을 것이다. 추후 지역축제에 대한 지역주민의 영향지각에 대한 조사를 지속적으로 실시하고 그 결과에 대한 세심한 모니터링을 함으로서 향후 지속가능한 축제가 성공적으로 진행될 수 있을 것이다.
