Tuberculosis (TB) is a significant public health concern. Globally, TB is among the top 10 and the leading cause of death due to a single infectious agent. Providing standard anti-TB therapy for at least 6 months is recommended as one of the crucial strategies to control the TB epidemic. However, the long duration of TB treatment raised the issue of non-adherence. Non-adherence to TB therapy could negatively affect clinical and public health outcomes. Thus, directly observed therapy (DOT) has been introduced as a standard strategy to improve anti-TB medication adherence. Nonetheless, the DOT approach has been criticized due to inconvenience, stigma, reduced economic productivity, and reduced quality of life, which ultimately could complicate adherence issues. Apart from that, its effectiveness in improving anti-TB adherence is debatable. Therefore, digital technology could be an essential tool to enhance the implementation of DOT. Incorporating the health belief model (HBM) into digital technology can further increase its effectiveness in changing behavior and improving medication adherence. This article aimed to review the latest evidence regarding TB medication non-adherence, its associated factors, DOT's efficacy and its alternatives, and the use of digital technology and HBM in improving medication adherence. This paper used the narrative review methodology to analyze related articles to address the study objectives. Conventional DOT has several disadvantages in TB management. Integrating HBM in digital technology development is potentially effective in improving medication adherence. Digital technology provides an opportunity to improve medication adherence to overcome various issues related to DOT implementation.

The forging process produces complicated and designed components in a die at high productivity for mass production and minimizes the machining amount for favorable material utilization; the forging products used at highly stressed sections are well accepted at a wide range of industry such as automobile, aerospace, electric appliance and et cetera. Accordingly, recent R&D activities have been emphasized on improvement of forging die-life and near net shaping technology for cost effectiveness and better performance. Usually closing and consolidation of internal void defects in a ingot is a vital matter when utilized as large forged products. It is important to develop cogging process for improvement of internal soundness without a void defect and cost reduction by solid forging alone with limited press capacity. For experiments of cogging process, hydraulic press with a capacity of 800 ton was used together with a small manipulator which was made for rotation and overlapping of a billet. Size of a void was categorized into two types; ${\phi}$ 6.0 mm and ${\phi}$ 9.0 mm to investigate the change of closing and consolidation of void defects existed in the large ingot during the cogging process. In addition for forming experiment of piston grown air drop hammer with a capacity of 16 ton was used. The experiment with piston crown was carried out to show the formability and void closing status. In this paper systematic configuration for closing process of void defects were expressed based on this experiment results in the cogging process. Also forging defects through forming process for piston crown was improved using the experiment results and FE analysis. Consequently this paper deals with the effect of radial parameters in cogging process on a void closure far large forged products and formability of piston crown.

컨테이너 터미널과 같이 다수의 AGV(Automated Guided Vehicle)를 한정된 공간에서 동시에 운용하는 환경에서는 AGV의 작업생산성에 악영향을 주는 충돌, 데드락(deadlock), 라이브락(liveiock)이 발생할 확률이 높다. 또한, AGV의 가/감속 운동은 AGV의 주행시간을 예측하기 어렵게 만들기 때문에 AGV 라우팅을 더욱 어렵게 만드는 요인이다. 본 논문에서는 AGV 사이의 충돌, 데드락, 라이브락을 방지하기 위해 점유영역 예약테이블(Occupancy Area Reservation table; OAR table)을 이용하는 방법과 최적주행경로를 선택하기 위해 가감속 운동을 고려하여 AGV의 주행시간을 추정하는 방법을 제안한다. 시간중심 시뮬레이 션(time-driven simulation)을 통해 제안방안을 실험 한 결과 제안방안의 효과를 확인하였다.

에너지가격의 인상과 고갈의 시대에 들면서, 사회적으로 에너지 정책에 대한 정부의 개입요구가 더욱 높아지고 있다. 에너지 정책 시행은 양면의 상반된 효과를 유발할 수 있다. 우선 긍정적인 면에서 에너지 수입의 감소를 통해 불필요한 외화유출을 방지할 수 있어 재원의 적절한 배분을 가능케 하고, 비싼 에너지 사용의 절약을 통해 가격 경쟁력을 제고할 수 있을 것이다. 이에 반해 무분별한 에너지 절약 정책의 경우, 투입재를 에너지에서 설비로 비합리적으로 대체하여 정책실적만 기록할 뿐이고 오히려 경제에서는 생산성을 저해하는 예기치 못한 부정적인 효과를 초래할 수도 있다. 에너지 정책에서 정책효과를 높이기 위해서는 경제를 구성하는 각 산업 부문별로 에너지 사용 형태를 분석하고 그 결과를 이해하는 노력이 선행되어야 한다. 이 점에서 본 연구는 거시적 접근법의 대표적 방법인 에너지 산업연관분석을 이용해 한국의 산업 부문별 에너지 소비행태를 분석하였다. 이를 통해 에너지 사용 집약도와 에너지원별 소비행태의 변화에 대한 계량적 분석을 수행하였다.

Technological substitution is the process by which a radical technology replaces the dominant technology in an industry. The processes of diffusion and substitution have been modeled extensively (Technology & innovation, 2010). However, the formulation of classical quantitative models encompasses only part of the theoretical space. These models impose many simplified constraints to the achievement of analytical resolution. The interior design organization needs to establish a set of technical system requirements by describing the scope of the accessibility needs of the organization against current technology use. Because of complicated design resources and ongoing advances in design technologies, design systems face the challenge of prioritizing new technologies for supporting. The problem is small design organization administration often displays a lack of concern toward the evaluation of technology integration. In this paper, I will identify the influence of a design organization's technology, and predict how future technology will inform, support, and potentially hinder productivity, culture, and work satisfaction within a design organization in the industry. In addition, I will use current design organizational behavior and leadership models to support my predictions. Finally, I will examine a proven approach to assist designers with evaluating technology integration in interior design organization. The goal is to develop a high quality, professional development scorecards for the evaluation. I will conduct both the evaluation of technology integration and CRM performance evaluation is recommended to assess the effectiveness of technology integration. Therefore, the evaluation of integration technologies oriented design hold the promise of solving the organization application integration challenge. The evaluation of integration technology is a significant pattern for processing such a vision. The careful selection of an integration technology for this purpose is crucial in contributing toward the success of such an interior design organization endeavor.

The GMA welding process involves large number of interdependent variables which may affect product quality, productivity and cost effectiveness. The relationships between process parameters for a fillet joint and bead geometry are complex because a number of process parameters are involved. To make the automated GMA welding, a method that predicts bead geometry and accomplishes the desired mechanical properties of the weldment should be developed. The developed method should also cover a wide range of material thicknesses and be applicable for all welding position. For the automatic welding system, the data must be available in the form of mathematical equations. In this study a new intelligent model with genetic algorithm has been proposed to investigate interrelationships between welding parameters and bead geometry for the automated GMA welding process. Through the developed model, the correlation between process parameters and bead geometry obtained from the actual experimental results, predicts that data did not show much of a difference, which means that it is quite suitable for the developed genetic algorithm. Progress to be able to control the process parameters in order to obtain the desired bead shape, as well as the systematic study of the genetic algorithm was developed on the basis of the data obtained through the experiments in this study can be applied. In addition, the developed genetic algorithm has the ability to predict the bead shape of the experimental results with satisfactory accuracy.
