With the advent of the 4th Industrial Revolution, diverse and a large amount of data has been accumulated now. The agricultural community has also collected environmental data that affects the growth of crops in smart farms or open fields with sensors. Environmental data has different features depending on where and when they are measured. Studies have been conducted using collected agricultural data to predict growth and yield with statistics and artificial intelligence. The results of these studies vary greatly depending on the data on which they are based. So, studies to enhance data quality have also been continuously conducted for performance improvement. A lot of data is required for high performance, but if there are outlier or missing values in the data, it can greatly affect the results even if the amount is sufficient. So, adjustment of outlier and missing values is essential in the data preprocessing. Therefore, this paper integrates data collected from actual farms and proposes a adjustment system for outlier and missing values based on it.

This study developed the in-situ stamp-forming process using the multi-axis robotic arm to fabricate thermal composite parts. Optimal fabrication parameters with the multi-axis robotic arm were determined using finite element analysis and these parameters were further refined through the practical manufacturing process. A comparison between the manufactured parts and finite element analysis results was conducted regarding thickness uniformity and wrinkle distribution to confirm the validity of the finite element analysis. Additionally, to evaluate the formability of the manufactured composite parts, measurements of crystallinity and porosity were taken. Consequently, this study establishes the feasibility of the In-situ stamp-forming consolidation using a robotic arm and verifies the potential for producing composite parts through this process.

Objectives: To evaluate the levels of exposure to organic compounds during aircraft disinfection and seat cover replacement operations. Methods: According to the working schedule, organic compounds were collected using activated carbon tubes and then analyzed by GC/FID and GC/MSD. Results: In the disinfection task, the main substances listed in the material safety data sheet (MSDS) of the disinfectant were not detected. However, 1-bromopropane, which had been used in the previous task of replacing seat covers, was detected at a level of 2.37 ppm at the measurement time. During seat cover replacement, bonding workers were exposed to 2.48 ppm on an eight-hour time-weighted average, and seat cover replacement workers were exposed to 0.22 ppm. Conclusions: It is necessary to ensure the reliability of MSDS. A work environment management system is necessary when different companies alternate working in the same place.

Korean arboretums where a large number of people are visiting could not do visitor's satisfaction in qualitative side and communication through education and event, although a lot of those things statistically have been doing so far. At this side, it needs an arboretum's segmentation: preparing to an adaptation strategy of a new paradigm, differentiated strategy, and problem solving strategy tied by a similar group for the Korean arboretum visitors. This research tries to classify several patterns with Korean arboretums by visitor's behavior and propose each type of subspecialized management plan after analyzing characteristic of supply and demand. The research for this tries to classify several patterns of Korean arboretum and suggest segmentalzed management plan by types after analyzing characteristics of aspects of demand and supply. By looking at the main patterning result of arboretum as a standard of the demand, there were four sorts of arboretums. In the first, it is the arboretum of intermediate type: not a clear characteristic. In the second, it is an arboretum of multipurpose resort type: strongly demanding motivational factors of a rest, health, access, low cost, experience, learning and sightseeing. In the third, it is an arboretum of theme tour type: a strong sightseeing motivational factor and demanding appreciate scenery. In the last, it is an arboretum of studying and admiring type: demanding a motivational factor of sightseeing landscape and plants, a strong experience and learning.

The radar installed on an aircraft has various operating modes depending on tactical purposes, allowing for the configuration of search areas according to each mode's operational objectives. active electronically scanned array (AESA) radar emits search beams sequentially according to a predefined search beam grid within the designated search area specified by the pilot to detect targets within it. It is crucial that the radar can stably search the area designated by the pilot for target detection, even as the aircraft's attitude changes. This paper focuses on stabilizing the search pattern in the air-to-air operational mode of aircraft-mounted radar to ensure stable target detection during roll and pitch maneuvers of the aircraft. The paper demonstrates its performance by simulating aircraft maneuvers and targets in a system integration laboratory (SIL) test environment.

Since the IFLA FRBR conceptual model, the transition to a data structure centered on entity-relationships has been underway. Reflecting this international trend, the draft of the 5th edition of the Korean Cataloging Rules (KCR5) were presented in May 2024. This study focused on the 'relationship' which provides additional information to users by connecting one entity with other entities. To this end, (1) the types of relationships between entities defined in the conceptual model and RDA cataloging rule were examined, (2) the actual cases of LC and PCC to record relationships in MARC21 based on RDA were analyzed, and finally (3) practical methods and challenges to be solved for applying them to KORMARC format were suggested. This study mainly utilized RDA training materials and data input guidelines of LC/PCC, and referred to full-MARC bibliographic records and authority records of LC and PCC participating libraries. This study aims to broaden the understanding of the new bibliographic structure and to prepare for the transition to the next-generation bibliographic structure such as BIBFRAME in the future.
