In this paper, an unmanned automation system for harvesting chili peppers through image recognition in the color space is proposed. We developed a cutting-edge technology in terms of convergence between information and communication technology (ICT) and agriculture. Agriculture requires a lot of manpower and entails hard work by the laborers. In this study, we developed an autonomous application that can obtain the head coordinates of a chili pepper using image recognition based on the OpenCV library. As an alternative solution to labor shortages in rural areas, a robot-based chili pepper harvester is proposed as a convergence technology between ICT and agriculture requiring hard labor. Although agriculture is currently a very important industry for human workers, in the future, we expect robots to have the capability of harvesting chili peppers autonomously.

TIP technology enables navigation of the internal contents of images by extracting geometry information from two-dimensional drawing or a picture and generating three-dimensional effects from extracted information. The technology can be applied to a variety of practical fields including game, entertainment, education, public relations and so on. This paper proposes extended application of TIP technology and realization method for smart devices using OpenGL ES Library for Android platform. Considering problems associated with a foreground object extraction, the proposed method uses vanishing points chosen by the user to facilitate more realistic scene configuration. Then, method acquires three-dimensional background model using OpenGL ES Library, develops three-dimensional virtual space and enables image navigation via camera viewpoint conversion. The experimental image is made on Android 2.1 and OpenGL ES 1.0 using the image taken on devices built on the Android platform. Thus, the proposed technology can be implemented to various smart devices built on the Android platform at lower cost and in less time.

Perceptions of Library and Information (LI) professionals in Nigeria and the impact of COVID-19 on libraries, librarians and library services, were studied. The significance of demographic factors on LI professionals' perception of COVID-19 and its impact on libraries was tested. Descriptive survey design and Purpose sampling technique were adopted. LIS professionals in Nigeria constituted the population, and an online questionnaire designed by the researchers through Microsoft Forms was used. Descriptive analysis of respondents' demographic data and their covid-19 perception were presented in frequencies and percentages using tables while multivariate regression technique was used to test the significance of relationship between variables at P < 0.05. Findings revealed that many (61.4%) of the respondents agreed that COVID-19 is real but have personal reservations. However, 47.5% indicated that COVID-19 is a scientific invention. On the impacts of COVID-19 on libraries, the study found that COVID-19 is a game changer that will enhance the creation of new services by libraries, cause the reconfiguration of library space for safe operations in post-COVID, establishment of new rules and regulations, and more reliance on e-resources. On the test of association, educational qualification of respondents had a significant impact on respondents' perceptions that COVID-19 will reduce the use of library print resources (P-value = 0.005, B: 0.38, [95% CI: 0.115 - 0.646]) and that library will create new services to address the changes caused by COVID-19. Also, educational qualification of respondents significantly influenced respondents' perception that COVID-19 is real. The study recommends that libraries should take advantage of the season to innovate, and that public health institutions should continually educate people on corona virus to disabuse people's mind of conspiracy theories.

In most countries, public libraries play a role as a knowledge and information hub for local communities, a complex cultural space, and a third place for meetings and communication. Among the work of public libraries for this purpose, the key point is systematic collection development, and the established collection is essential for all knowledge and information services. In particular, local representative libraries must perform legal duties as a comprehensive knowledge information center for metropolitan governments, and develop, preserve, and service specialized collections that are difficult for other public libraries. Therefore, we analyzed the development cases of specialized collections of public libraries in large cities in foreign countries and local representative libraries in Korea, surveyed the degree of awareness of specialized collections for employees of public libraries and the cultural to geography in Gyeongbuk region. Based on the background information, this study proposed the development plan and establishment strategy of the Gyeongbuk Library specialized collection, which was named "Gyeongbuk Knowledge and Cultural Heritage."

In the Fourth Industrial Revolution, students are required to develop in areas such as communication, logic, and creative thinking. Therefore, the university libraries need to develop new services so that students can grow up to be suitable for the new social situations. Havruta is an educational approach that can meet these needs and is one of the measures the university libraries want to apply. Thus, through 1) the investigation of the concept of Havruta, 2) the case study of domestic and foreign university libraries, and 3) interview of the Havtura-based service, this study 4) proposed the Havruta service applicable to the university libraries and 5) conducted a survey of operators and users on the awareness of the Havruta service, space, and contents of the Havruta service, and the willingness of the Havruta service. Results of the survey analysis revealed implications for the areas of the Havruta service - Havruta theme, group organization, textbook rental, simplication of space reservation, data sharing and motivation system.

This study was conducted to identify the operation status of Dobong-gu public libraries in order to establish a mid- to long-term development plan for Dobong-gu libraries, and to analyze local residents' perceptions of libraries by factors through user surveys to suggest specific development plans for Dobong-gu libraries. Overall, the satisfaction level of Dobong-gu residents with library services was found to be high, and all libraries were analyzed to be providing high-quality services. From this, the following operational strategies for the mid- to long-term development plan of Dobong-gu public libraries can be derived. First, libraries need to continue to collect and provide books that meet the quantitative and qualitative levels to satisfy the needs of the community and users. Electronic and online materials, including e-books and audiobooks, as well as subject-specific materials should be expanded to provide relevant programs. Second, although Dobong-gu is an aging city, a wide range of age live there, so there is a need to promote communication and understanding between generations and promote integration of the community through a generational empathy program. Third, it is necessary to remodel and improve the space of aging libraries by organizing library facilities and environments into open spaces and creating makerspaces and multicultural spaces for direct experience and practice, reflecting the latest trends in library space organization.

Public libraries have been facing new challenges as the number of channels providing information resources has been increasing due to information and communication technology development. The perception of public libraries of the general public is that they should continue to play a substantial role in information services. However, the libraries' environments are changing, and the public's needs are diversifying, so public libraries also need to differentiate themselves from other organizations that provide similar services. This paper proposes branding as a solution to create differentiation. The study conducted a questionnaire survey with Koreans in their 20s. A series of statistical tests with the survey data showed the impact of the brand association elements on customer satisfaction and brand loyalty and identified unique factors in public libraries. For example, Brand associations such as material-based services, benefits, and attitude affected both dependent variables. On the other hand, the non-product association such as space/place images did not. Based on these findings, we provided implications for introducing branding in public libraries.

Monolithic three-dimensional (M3D) logics such as M3D-NAND, M3D-NOR, M3D-buffer, M3D 2×1 multiplexer, and M3D D flip-flop, consisting of modularized M3D inverters (M3D-INVs), have been proposed. In the previous M3D logic, each M3D logic had to be designed separately for a standard cell library. The proposed M3D logic is designed by placing modularized M3D-INVs and connecting interconnects such as metal lines or monolithic inter-tier-vias between M3D-INVs. The electrical characteristics of the previous and proposed M3D logics were simulated using the technology computer-aided design and Simulation Program with Integrated Circuit Emphasis with the extracted parameters of the previously developed LETI-UTSOI MOSFET model for n- and p-type MOSFETs and the extracted external capacitances. The area, propagation delay, falling/rising times, and dynamic power consumption of the proposed M3D logic are lower than those of previous versions. Despite the larger space and lower performance of the proposed M3D logic in comparison to the previous versions, it can be easily designed with a single modularized M3D-INV and without having to design all layouts of the logic gates separately.

In order to establish the effective community village as planned, it is the most important factor in residents' participation at the stage of design process. Especially, community space, which is commonly used by all members, must be designed through consultation process of community members themselves to accommodate the needs of various daily activities. So, in this study, the participation process to design the common community facility is developed and the actual residents' participation workshop was conducted in Baek-Hwa village, which is being built on South Korea. Also, the space of community facilities was designed based on the direct opinions and needs of actual residents obtained by workshop process. The workshop was conducted two times: the first workshop was conducted for the design of common residents' facilities and the second was for trying to utilize the virtual designed space. During the workshop process, it is found that the positive participation of members of village is naturally occurred to design residents' space in the workshop process. As a result, most people want to make the space of gym, library, and dining room in spatial configuration. Among them, the hobby room was highly demanded. There is lots of demand for the joint activities and training program in common activity fields. Also, the prediction of the various occurrence so fun expected situations was requested in the game of creating rules and role-playing. In the conclusion, it was acknowledged the necessity of residents' participation design and the importance of communication between architects and residents for decision-making.
