  • It is well recognized that, in most developing countries, rapid population growth has been a serious problem. And there is a growing tendency to regard the problem as a political issue in these coun-tries. So far, many developing countries have formulated and implemented population policies aiming at an reduction of such population growth. This study attempts, in policy perspective, to examine theoretically the process and determinants of population policy making and implementation in those developing countries. In doing this, it gives emphasis on explaining population policy determinants and therefore, deals with (1) decision makers' perceptions and attitudes, (2) governmental structure and capability, (3) mass fertiliry behavior, and (4) foreign aid agencies' role.

  • In this paper, a closed hydroponics device was designed and fabricated to grow and harvest plants in a small space for safe consumption, which enables horticultural activities that are difficult to perform due to space constraints from urbanization. This device also aimed to minimize the air pollution of crops. To obtain data for the optimal growth conditions for crops in this intelligent plant-growing system, sensors were used to measure and control the growth conditions. To investigate the optimal growth conditions, blue lettuce and crown daisy were selected as representative crops. The growth rates were comparatively analyzed through four experiments for each plant. This hydroponics device was used to collect data on growth rates that are altered depending on cultivation conditions, which can then be used to study methods to control the growth rate of crops.

  • There is a growing interest in ethical consumption, and consumers are demanding high levels of CSR for their companies. Transparent provision of corporate information among various areas of CSR is also an important topic in the recent consumption situation. In the global fashion industry, it is also a type of radical corporate transparency and ethical management, led by several advanced startups such as Everlane. As a result, the production process is being disclosed. This study empirically analyzes the influence of this fashion product process transparency on the consumer evaluation of the company. According to a survey of 200 Korean respondents, the transparency of the presented fashion firms had a positive effect on corporate trust and purchase intention. It was confirmed that it has. On the other hand, consumer involvement, which has been discussed as an important personal attribute in the associated consumption environment, has no significant moderating effect. In other words, consumers' subjective corporate ethics involvement did not have a significant influence on their corporate transparency evaluation.

  • A decrease in the fertility rate leads to a reduction of troops, so the need to efficiently operate the troops is growing. Therefore, it is necessary to develop a system for estimating warship manpower. In this study, system development was performed according to the CBD methodology. The user requirements were defined and the system function that satisfies the requirements was derived. And through the development process, the CBD methodology and the systems engineering process were compared. As a result, similarities were confirmed in the analysis and concept design stages, so the possibility of merging the two processes was suggested.

  • To solve the challenge of waste plastics, this study investigated the related technologies and company trends along the plastic life cycle, and primarily describes ICT technologies to improve efficiency in the process of sorting and sorting waste plastics. Waste plastic discharge caused by the explosive increase in parcel traffic because of COVID-19 is also growing exponentially. Hence, waste treatment is emerging as a social challenge. Most of the domestic waste classification depends on the manual process according to the waste pollution level. The plastic material classification approach using the spectroscopy approach reveals a high error in the contaminated waste plastic classification, but if the Artificial Intelligence-based image classification technology is employed together, the classification precision can be enhanced because of the type of waste plastic product and the contaminated part can be differentiated.

  • The development in the design process is usually based on the choice of a method for designing the system, in which this method is frequently faced with tightening environmental requirements, reducing development cycle times and growing complexity. To tackle such factors, the paper proposes a comprehensive approach focusing on applying systems engineering approach to the building design support. In particular, this paper addresses all capabilities of using some available systems engineering standards (like EIA-632) in the design process. Then, a methodological approach is proposed for the practice of requirements engineering by applying quality assessment and control to design in early phase. The paradigm used, here is to extend and particularly to adapt the work carried out in military and space systems to modern building services by taking into account the semantics of buildings in terms of different engineering fields and architecture issues.

  • Companies display the product information to the consumers in their online presences. As importance of online marketing activities are growing, most of the franchisers also uses the product images on their online sites to provide the vivid visual information of their merchandises. But the previous researches do not provide the rigorous understanding on the nature of how the consumers process the visual information. In this study, we explore the theoretical backgrounds of the visual information processing and set up the research proposition on the orders and directions of the online visitors' attentions. The visit data from experimental online shop for 81 days was analysed with repeated measure ANOVA. We found that the nature of visual information processing in the online environment is different from that of the ordinary text process. At the end of this study, implication and the limitations of the research were discussed.

  • There has been growing interests in life-cycle project management in the construction industry. A lot of attention is given to Building Information Modeling (BIM) which stores and uses a variety of construction information for the life cycle of project management. However, due to the additional workload arising from BIM, its expected effects versus its input costs are still under discussion in practice. As an attempt to address this issue, one of previous studies suggested an automated linking process by developing Standard Classification Numbering System (SCNS) and Geometry Breakdown Structure (GBS) to enhance the efficiency of integration process of BIM objects, cost, and schedule. Though SCNS and GBS facilitates identifying all different dataset, making object sets and linking schedule activities still needs to be manually done without having an automated tool. In this context, the purpose of this paper is to develop and validate a fully automated integration system for 3D-objects, cost, and schedule. A prototype system for single family homes (Hanok) was developed and tested in order to verify its efficiency.

  • Building Information Modeling (BIM) design has been mandatory in Korea since 2016, and it has been gradually expanding in the industry, with a slow attempt to apply it in remodeling constructions. This is because Korea is facing a situation where many buildings are over 30 years old and require remodeling or reconstruction. The remodeling industry is also a growing market, as it saves construction time and cost compared to reconstruction. BIM is an ideal technology element for a competitive remodeling construction, as remodeling constructions face a complicated construction process from the start, including demolition, maintenance, and reinforcement to save the change process. However, there are still limitations in applying BIM to remodeling constructions, due to considerations of the existing building and the complicated requests of the inhabitants. BIM still has technical and environmental limitations for general use. In this study, I analyzed BIM application cases from existing studies and suggest what improvement points should be strengthened.
