블록체인은 유전자분석 서비스의 한계점인 개인정보 유출, 데이터 관리 이슈 등을 해결하고 이를 활성화할 핵심기술로 주목받고 있다. 유전자분석 서비스는 지속적 비용 감소와 규제환경 변화로 인해 시장규모가 증대해 왔으며, 뛰어난 보안과 다양한 서비스와 연결이 가능한 블록체인이 결합될 경우, 잠재성이 더욱 커질 것으로 예상된다. 이 연구에서는 기술수용모델(TAM)과 혁신저항이론을 결합해 연구 모형을 제작, 블록체인 속성 중 차세대 유전자분석 서비스의 수용의도와 혁신 저항에 영향을 미치는 요인들을 분석한다. 이러한 분석을 위해 블록체인 및 유전자분석 서비스에 대한 잠재적 사용자가 될 150여 명을 대상으로 설문조사를 진행하였다. 수용의도 및 저항에 영향을 줄 것이라고 추론하는 블록체인의 4자기 속성 즉, 보안성, 투명성, 가용성, 다양성 등을 연구변수로 설정하여 분석을 진행했다. 기술수용 및 혁신저항 변수에는 인지된 유용성, 인지된 위험, 인지된 복잡성 등을 설정하여, 블록체인의 특성이 매개변수를 통해 수용의도와 혁신저항에 미치는 영향을 분석했다. 이러한 분석을 통해 차세대 유전자분석 정보플랫폼의 저항을 줄이고 수용의도를 높이기 위해 중요하게 고려해야할 핵심변수를 가려낸다. 이 연구는 블록체인 기반의 새로운 유전자분석 정보플랫폼을 준비하는 업체에서 서비스 고도화를 위해 고려해야 할 혁신요인을 제시한다는 점에서 의의가 있다.

A mixed model assembly line (MMAL) is a special type of production line where a variety of product models similar in product characteristics are assembled. Determining the model sequence is an important problem for the efficient use of MMALs. This paper considers interactive multiobjective decision making problems for MMAL sequencing. Evolution program is employed as an underlying framework. In this study, a way of approximating the linear utility function is first studied. To improve its search efficiency to the solution space preferred by a decision maker, some modifications of a standard evolution program are made: operating several subpopulations instead of a single population and merging two or more subpopulations to a single subpopulation, and using a Pareto pool. Extensive computational experiments are carried out to verify the performance of the proposed approach. The computational results show that our approach is promising in solution quality.

In mixed-model production systems, various models of products are produced alternately on the same production line. When the total number of models or the total production quantity is large, it takes a long time to determine the production sequence of the products. In this paper, we will show that in case of product rate variation problem (PRV) problem with nonidentical symmetric convex discrepancy function, an optimum sequence can be obtained by repeating an optimum sequence in a reduced subproblem.

This paper is concerned with the integrated problem of line balancing and model sequencing in mixed model assembly lines(MMALBS), which is important to efficient utilization of the lines. In the problem, we deal with the objective of minimizing the overall line length To apply the GAs to MMALBS problems, we suggest a GA representation which suitable for its problems, an efficient decoding technique for the objective, and genetic operators which produce feasible offsprings. Extensive experiments are carried out to analyze the performance of the proposed algorithm. The computational results show that our algorithm is promising in solution quality.

This paper suggests an e-learning system model, a goal-driven personalized e-learning system, which increase the effectiveness of learning. An e-learning system following this model makes the learner choose the learning goal. The learner's choice would lead learning. Therefore, the system enables a personalized adaptive learning, which will raise the effectiveness of learning. Moreover, this paper proposes a SCORM standard, which modifies SCORM 2004 that has been insufficient to implement the "goal driven personalized e-learning system." We add a data model representing the goal that motivates learning, and propose a standard for statistics on learning objects usage. We propose each standard for contents model and sequencing information model which are parts of "goal driven personalized e-learning system." We also propose that manifest file should be added for the standard for contents model, and the file which represents the information of hierarchical structure and general learning paths should be added for the standard for sequencing information model. As a result, the system could sequence and search learning objects. We proposed an e-learning system and modified SCORM standards by considering the many factors of adaptive learning. We expect that the system enables us to optimally design personalized e-learning system.

This paper discusses a brcriterion approachto sequencing with time/cost trade-offs. The first problem is to minimize the total flow time and the maximum tardiness. And second is to the maximum tardiness and resource allocation costs. This approach , which produces an efficient frontier of possible schedules, has the advantage that it does not require the sequencing criteria to be measurable in the same units as the resource allocation cost. The basic single machine model is used to treat a class of problems in which the sequencing objective is to minimize the maximum completion penalty. It is further assumed that resource allocation costs can be represented by linear time/cost function.

The unique Br signature was utilized for C-terminal amino acid sequencing of model peptides. C-terminal carboxyl group was selectively derivatized in peptides, containing side chain carboxyl group, using 1-ethyl-3-[3-dimethylaminopropyl]carbodiimide hydrochloride (EDC) and Br was introduced using 4-bromophenylhydrazine hydrochloride (BPH) in a one pot reaction. Matrix-assisted laser desorption/ionization (MALDI) time-of-flight (TOF) tandem mass spectra were obtained carrying the Br signature in the y-series ions. The Br signature facilitated C-terminal sequencing and discrimination of C-terminal carboxyl groups in the free acid and amide forms.
