This study aimed to propose considerations for attributes and their standardization strategies during the data collection process for electronic publications by domestic distributors for the National Library of Korea. The research identified a total of 21 essential and optional attributes based on a survey and a Focused Group Interview (FGI) with the staff responsible for legal deposit and acquisition tasks at the National Library of Korea. Additional attributes were found necessary during the data quality verification process, leading to the specification of essential and optional attributes for various types of materials, including eBooks, audiobooks, webtoons, and web novels. The standardization of attribute values, essential for enhancing the identifiability and management efficiency of electronic publications, included adherence to ISO 8601 rules for dates and times, clear designation of limited-range attribute values such as file format and adult content, and detailed description of information related to titles. Furthermore, the study highlighted the need for establishing standardized metadata requirements and continuous data quality management and monitoring systems.

This paper suggests a TCP/IP-based remote data monitoring system, which combines PDA (Personal Digital Assistant) and WLAN (Wireless Local Area Network) technologies. Wireless PDA devices are used for remote monitoring of wireless communication by continuously collecting remote device data transmitted from servers such as temperature, humidity and device status, and displaying them on mobile devices. Therefore, remote data monitoring systems that integrate wireless and wired services provide data collection adaptive to administrators and efficient identification of device status.

Electronic Toll Collection (ETC) System makes the telecommunication possible between the Beacon and the On Board Unit(OBU) for automatic toll collection. In this paper, the propagation path of microwave is modelled and the induced voltage of receiving antenna is analyzed numerically according to multi-path fading effect. In our modelling, we consider frequency, weather condition, polarization and antenna radiation pattern. Also, we suggest the diversity technique in order to reduce the fading effect. In the resuts, the fading effect is reduced significantly in case of the vertical polarization at the rain condition. In general the circular polarization is the most desirable in this application. The antenna which has the high directivity, is also desirable. Using the space and frequency diversity technique at the Beacon, the fading effect is reduced effectively. These results are compared with our experimental data.

In this paper, we propose the sensor and the signal duplicator for the automatic building control. Developed duplicator realizes the sensor data collection apparatus and mimics the measured data and, thus, reduces the construction cost by using logical communication layer. Furthermore, the system supports the open protocols and can be associated with HMI(Human Machine Interface) used on the market. Developed duplicator is proved to be functional within the real environment. Measurement error rate, operating temperature, and operating humidity show very good results by the certified testing apparatus and organization.

The study tested a hybrid model with constructs drawn from the Technology Acceptance Model (TAM) and Diffusion of Innovation (DOI) theory in order to examine the moderating effect of productivity and relative advantage (RA) on perceived usefulness (PU) vis-à-vis electronic information resources (EIR) adoption in private university libraries in Ogun and Osun States of Nigeria. The descriptive research design was adopted in the study. The population consisted of 61 (55.0%) librarians and 50 (45.0%) library officers (totaling 116—100%) in Babcock University, Bells University, Covenant University, Bowen University, Oduduwa University, and Redeemer's University. Purposive sampling procedure was adopted after which total enumeration was used since the total population is small. The questionnaire was used for data collection. Of the 116 copies of the questionnaire administered, 111 (95.7%) were found usable. The instrument was structured based on a 4-point Likert agreement scale of Strongly Agree, Agree, Disagree, and Strongly Disagree. Data were analyzed using descriptive statistics like tables of frequency counts and percentage. The findings revealed that productivity and relative advantage are significant moderators of perceived usefulness of EIR adoption in private university libraries in Ogun and Osun States, Nigeria.

The aim of this study was to investigate why people voluntarily contribute knowledge to others, primarily strangers, in the electronic network of practice for job examination expected potential competing. This paper is organized as follows. First, we introduce the electronic network of practice which is the knowledge sharing community for job examination, and discuss the key issues for understanding knowledge sharing in these networks on the basis of individual motivations, relational capital, sense of community, and sense of rivalry to develop a research model for this study. To test the proposed research model, we adopted the survey method for data collection, and examined our hypotheses by applying the multiple regression analysis method to the collected data. Our unit of analysis was the individual. The findings of this study show that the intention of knowledge sharing is influenced by the reputation and the enjoy helping as the factors of individual motivations, by the reciprocity as the factor of relational capital, and by a sense of rivalry as a psychological factor. Lastly, contributions of this study and future research opportunities are also discussed.

Smart livestock, which combines information and communication technology (ICT) with livestock, can be said to be an effective solution to existing livestock problems such as productivity improvement, odors, and diseases. So far, it has hardly been universalized; thus, it is necessary to develop automation devices to reduce labor by localizing automation devices to expand the distribution of ICT technology to farms, and to advance precise specifications and health management technology using biometric information. Weighing scales currently being used in livestock farms are to prevent the spread of diseases by diagnosis and preparation for AI and other diseases in advance, using information on the growing weight of duck breeding. However, accurate values cannot be obtained due to poor breeding conditions. In this paper, we developed a separate data transmission system kit for the weighing scale and placed the sensor on top of the weighing scale so that the sensor wire is not affected by pollutants or ducks on the floor. A display function was provided, and a method of receiving and analyzing the serial port data of the weighing device, and then transmitting them to the data collection server was implemented.

현재 국내에서 ITS(Intelligent Transport Systems) 통신방식으로 이 용되고 있는 DSRC 방식은 TTA(한국정보통신기술협회)의 기술표준으로서 대전시,전주시에 적용되어 BIS(Bus Information Service)에 이용되고 있고,최근 고속도로 ETCS(Electronic Toll Collection System)가 DSRC방식으로 전국고속도로 Tollgate 에서 2007년 연말에 개통될 예정이다. DSRC 방식은 2000년에 TTA(한국정보통신기술협회)에서 기술표준이 제정되어 현재 1Mbps 의 Data 용량을 가진다. DSRC 방식의 물리링크 변조방식은 ASK(Amplitude Shift Keying)로 ITS 확장 서비스 적용을 위해 변조방식을 QPSK(Quadrature Phase Shift Keying )로 개선하게 되면 이론적으로 4배의 Data Rate 향상이 이루어진다. 물리적인 RF 변조방식을 ASK에서 QPSK로 바꿔 간단히 Data Rate을 개선하게 되면 회로구현의 경제성이 향상되어 DSRC 응용 서비스가 활성화 될 것이다.

Objectives: This study aimed to analyze the papers on nursing in the KJHSM (Korean Journal of Health Service Management) (2007-2018), to identify the research trends and to help the future development of nursing research. Methods: The data collection was carried out from September 1, 2019 to September 30, 2019. The 78 copies of the original text were provided by the KSHSM website, DBpia, and NDSL (National Digital Science Library) electronic database. Results: Forty-seven studies had a non-experimental design, with most having a descriptive research design (89.3%). The most common participants were nurses (55.7%) and nursing college students (26.1%). A questionnaire was the most commonly used research tools (96.2%) and data collection methods (95.0%). The major keywords were the terms included in the environmental domain among the meta-paradigms of nursing (43.6%). Conclusions: In order to expand the quantity and quality of nursing science in the KSHSM, efforts are needed to improve the quality of research participants, research tools, and sampling methods.
