자연계에서 존재하는 다양한 생명체는 자신들의 생존과 종의 번성을 위해 효율적인 행동 규칙을 만들어 진화해 왔다. 이러한 생명체의 다양한 생존원리로부터 착안을 하여 자연계가 아닌 다른 환경에서 적용이 가능하도록 알고리즘을 만들어 적용시키는 것을 생체모방 알고리즘이라 한다. 자연계의 환경자체가 불확실한 변화가 다양하게 포함되고 있으며, 제한된 자원 환경을 어떻게 효율적으로 활용하는가의 문제가 걸려 있음으로 인하여 이러한 생체모방 알고리즘은 적용환경의 변환에 빠른 적응력을 제공할 수 있고, 자원 제약형 환경에서 안정적으로 확장성과 적응성을 제공할 수 있어서 상호 운용성 측면에서 많은 이득을 줄 수 있다. 이와 같은 생체모방 알고리즘을 네트워크의 관점에서 적용시켜 보면, 전자의 경우에는 자율적인 네트워크 구성을 용이하게 제공할 수 있음을 나타내고, 후자의 경우에는 IoT 환경과 같은 자원 제약형 환경에서의 상호 운용성을 제공할 수 있다. 이렇듯이 생체모방 알고리즘을 네트워크에 접목시켜 연구하는 것은 최근의 네트워크 분야의 연구 이슈와 상호 보완적으로 작용하여 시너지 효과를 제공할 수 있다. 자연계의 군집 현상 및 동기화 현상을 네트워크 환경에서 적용하여 사용할 수 있는 생체모방 알고리즘 기술은 다양하게 존재하고 있으며 이를 활용하는 연구를 통해 SDN(Software Defined Networking)에서의 자율제어 네트워크 구성에 접목하거나 IoT 환경과 같은 자원 제약형 환경에서의 보다 효율적인 상호 연결성을 제공하는 방향으로 발전할 수 있다. 이러한 생체모방 자율제어 네트워크 환경 구현을 위해 기존의 OpenFlow 환경과 새로이 부각되는 P4: Programming Protocol-Independent Packet Processors 기술에 대해서 정리하여 향후 생체모방 자율제어 네트워크 구현 방안을 제시하고자 한다.

Self-driving vehicles are increasing as new alternatives to solving problems such as human safety, environment and aging. And such technology development has a great ripple effect on other industries. However, various problems are occurring. The number of casualties caused by self-driving is increasing. Although the collision of fixed obstacles is somewhat decreasing, on the contrary, the technology by active obstacles is still insignificant. Therefore, in this study, in order to solve the core problem of self-driving vehicles, we propose a method of extracting active obstacles on the road. First, a center scene is extracted from a continuous image. In addition, it was proposed to extract activity obstacles using activity size and activity repeatability information from objects included in the center scene. The center scene is calculated using region segmentation and merging. Based on these results, the size of the frequency for each pixel in the region was calculated and the size of the activity of the obstacle was calculated using information that frequently appears in activity. Compared to the results extracted directly by humans, the extraction accuracy was somewhat lower, but satisfactory results were obtained. Therefore, it is believed that the proposed method will contribute to solving the problems of self-driving and reducing human accidents.

This study aims to study the impact of pet attachment on subjective well-being, focusing on individuals who live with pets. In addition, it is to recognize that their basic psychological requirement mediates between pet attachment and subjective well-being. For this purpose, a survey was performed on 358 adults living with pets nationwide. The final data of 319 people were evaluated after excluding invalid information. Dependent on the theoretical approach of the attachment theory, the human-pet relationship was examined by dividing it into two orthogonal dimensions pet attachment prevention and pet attachment anxiety(Zilcha-Mano et al., 2011). The mediating effects were investigated as an in-depth mechanism that mediates between pet attachment and subjective well-being, the mediating effects were examined, in terms of the three basic psychological needs of Self-Determination Theory, which are autonomy, competence, and relatedness. As an outcome, first, pet attachment prevention and pet attachment anxiety both revealed a negative correlation with subjective well-being. Second, basic psychological needs, which are autonomy, competence, and relatedness, are mediated between pet attachment and subjective well-being. Autonomy, competence, and relatedness fully mediated the relationship between pet attachment avoidance and subjective well-being. Meanwhile, in the case of pet attachment anxiety, only autonomy among basic psychological needs is fully mediated between pet attachment anxiety and subjective well-being in the case of pet attachment avoidance. This means that pet attachment prevention or pet attachment anxiety correlates with subjective well-being by satisfying basic psychological needs instead of directly affecting personal well-being. Regarding the pet effect, it is meaningful to find an in-depth mechanism that the human-pet relationship has for an adaptive and positive impact on humans.

Recently, public libraries have increased in quantity, while various problems have arisen regarding the operation of public libraries, such as lack of librarian manpower and facilities. Additionally, an increase in the number of public libraries does not correlate to an increase in the utilization of public libraries, and thus developing various services is needed to maintain the continued use of public libraries. This study examined which types of use motivations affect the intention of knowledge exchange in public libraries when using public libraries based on the self-determination theory. It also looked at how the use motivations and the intention of knowledge exchange vary depending on the frequency of public library use. According to an online survey of 230 users of public libraries, extrinsic motivation, intrinsic motivation, autonomy, competence, and relatedness as independent variables had a positive impact on the level of knowledge exchange. In addition, the higher the frequency of public library use, the higher the needs for autonomy and relatedness were. Based on the results, it was suggested that the knowledge exchange needs to be established as a new service of public libraries by offsetting extrinsic motivation that emerged from by negative influences and promoting intrinsic motivation, autonomy and competence.

This study collected 1,870 English news articles related to research and development of autonomous vehicles in order to identify various issues emerging in the research and development process of autonomous vehicles at home and abroad, and conducted topic modeling after data pre-processing. As a result of topic modeling, we extracted 20 topics, and we performed naming operations for topics and interpreted their meanings. A logical model for autonomous vehicle research and development projects was presented in response to the R&D process of input, activity, output, and outcome of derived topics. The analysis results of this study will be used as basic data to accurately determine the progress of domestic and foreign self-driving car research and development projects and prepare for the rapidly changing technology development.

The introduction of autonomous vehicles will bring about not only changes in existing automotive ecosystem but also widespread changes in our lives, society, economy, and culture. Social acceptance is one of important influencing factors for the commercialization of autonomous vehicles. The purpose of this study analyzes influencing factors in the acceptance of autonomous vehicles in terms of consumers. Autonomous vehicles in this study were defined as PAV (Partial Autonomous Vehicles) and FAV (Full Autonomous Vehicles) by drivers' intervention or not. The survey was conducted over 20 years old including not only drivers but also non-drivers. The results showed that the factors affecting acceptance of PAV and FAV were different. Factors directly related to drivers influenced PAV acceptance while external environmental factors influenced FAV acceptance. This study is proved that is should need different strategies between PAV and FAV for increasing those acceptance
