이전의 선행연구에서 제시된 인공 잠재지문 수용액은 실제 잠재지문 현출력에서 부족한 결과를 보였다. 이에 본 연구에서는 지질 성분을 개선하여 실제 지문 조성과 유사한 인공 잠재지문 수용액을 개발하였다. 아미노산 수용액과 지질 수용액을 부피 비 3:2, 4:1, 5:1, 8:1, 10:1, 20:1로 혼합하여 일정량을 다공성 표면인 종이와 비다공성 표면인 슬라이드 글라스에 떨어뜨린 후 각각 Oil red O, Cyanoacrylate 기법 및 Basic yellow 40 염색을 적용하여 현출하였다. 지질의 농도가 감소할수록 현출력 또한 감소하였지만, 두 종류의 표면 및 모든 농도에서 충분히 육안으로 식별되었다. 또한 기존에 제시된 인공 잠재지문 수용액과 비교하였을 때 지질 반응성 지문 현출 시약에 대한 반응성이 현저히 높은 것을 확인할 수 있었다. 향후 본 인공 잠재지문 수용액을 지문 융선대로 프린팅하여 실제 잠재지문과 조성이 유사한 인공 잠재지문을 제작하여 지문 연구에 대한 정량적인 샘플 제작이 가능할 것으로 기대된다.

We consider the Inventory Routing problem(IRP) for the vending machine operating system. An artificial immune system(AIS) is introduced to solve the IRP. The IPR is an rolling wave planning. The previous solution of IRP is one of good initial solution of current IRP. We introduce an Artificial Immune system with memory cell (AISM) which store previous solution in memory cell and use an initial solution for current problem. Experiment results shows that AISM reduced calculations time in relatively less demand uncertainty.

In this study, the author introduces a supply-chain management (SCM) solution that connects suppliers, manufacturers, customers, and other companies within a transactional relationship to enable efficient inventory management and timely product supply, which ultimately maximizes corporate profits. This proposed solution exploits Fourth Industrial Revolution technologies, such as artificial intelligence (AI) and the Internet of Things (IoT), which provide solutions to complex management issues generated by the broader market. The goal of the current study was to develop an advanced and intelligent smart SCM solution that complies with logistics standards, to enhance the visibility, safety, and efficiency of a supply chain made up of manufacturers and suppliers. This smart SCM solution aims at maximizing corporate profits through efficient inventory management and timely supply of products, and solves the complex management problems caused by operating within a wide range of markets.

Basic investigations have been carried out for the solvent extraction of silver contained in the waste photographic fixing solution using D2EHPA as an extractant. Extraction experiments were conducted using artificial waste solution which was made by dissolving $AgNO_3$ in distilled water along with actual waste fixing solution. For artificial waste solution, the extraction of silver was found to occur very rapidly at the initial stage of extraction. In addition, more silver was extracted as the volumetric ratio between aqueous phase and organic phase was decreased. The volumetric ratio of organic extractant to diluent was also taken as an influential variable and the extracted amount of silver was observed to decrease with temperature. The characteristics of silver extraction for actual fixing solution was generally similar to that for artificial waste solution. Regarding the kinetic analysis, the extraction of silver contained in the actual solution was observed to follow a first order reaction.

Viscous analysis on incompressible flows is performed using unstructured triangular meshes. A two-dimensional and axisymmetric incompressible Navier-Stokes equations are solved in time-marching form by artificial compressibility method. The governing equations are discretized by a cell-centered based finite-volume method. and a centered scheme is used for inviscid and viscous fluxes with fourth order artificial dissipation. An explicit multi-stage Runge-Kutta method is used for the time integration with local time stepping and implicit residual smoothing. Convergence properties are examined and solution accuracies are also validated with benchmark solution and experiment.

중금속 오염원을 제거하는 기술을 개발하고자 미나리를 도입하여 중금속 종류에 따른 적정 농도별로 중금속 흡수, 정화효율성 및 식물체내에서 중금속 축적과 이행과정을 조사하였다. 미나리를 이용한 중금속 정화효율성은 Cd의 경우 미나리 정식 6일 후 Artificial solution 처리구와 문막 공업폐수 처리구는 각각 53%, 73%의 정화효율성을 보였으며, Cu의 경우에는 각각 28%, 100%의 정화효율성을 보였다. 환경부에서 규정한 Cd의 청정지역 배출허용기준인 0.02 mg/L은 모든 처리구에서 10일 이후에 나타났으며, Cu의 기준농도인 0.5 mg/L은 Artificial solution 처리구의 경우 10일 이후, 문막 공업폐수 처리구는 3시간 이후에 나타났다. 또한 시간이 경과함에 따라 미나리내 중금속의 축적농도는 높아지는 경향을 보였으며, 처리구의 오염수 중금속 농도보다도 5$\sim$10배 이상 축적되었다. 미나리 식물체에 흡수된 중금속의 뿌리에서 지상부로의 이행율은 Artificial solution 처리구에서 Cd은 25%, 문막 공업폐수 처리구에서 Cu는 25% 이행하였다. 중금속에 대한 미나리의 생육반응은 문막 공업폐수 처리를 제외한 모든 처리구에서 미나리 생장이 억제되는 결과를 보였다. 따라서 본 연구결과 미나리는 중금속 오염수의 중금속 정화를 위한 식물정화기술에 유용하게 활용할 수 있을 것으로 판단된다.

This paper proposes a Pareto artificial life algorithm for solving multi-objective optimization problems. The artificial life algorithm for optimization problem with a single objective function is improved to handle Pareto optimization problem through incorporating the new method to estimate the fitness value for a solution and the Pareto list to memorize and to improve the Pareto optimal set. The proposed algorithm was applied to the optimum design of a journal bearing which has two objective functions. The Pareto front and the optimal solution set for the application were presented to give the possible solutions to a decision maker or a designer. Furthermore, the relation between linearly combined single-objective optimization problem and Pareto optimization problem has been studied.

The objective of this paper is to propose a Binary Artificial Bee Colony (BABC) to obtain the best/optimal solution for NP-hard scheduling problem of railway track maintenance. We can greatly maximize the objective value using proposed BABC within limited computation time. The proposed BABC mechanism is very efficient to find the best solution because of employing fewer control parameters.
