This study used text mining, a big data analysis technique, to explore XR trends in South Korea. For this research, I utilized a big data platform called BigKinds. I collected data focusing on the keyword 'XR', spanning approximately 14 years from 2010 to 2024. The gathered data underwent a cleansing process and was analyzed in three ways: keyword trend analysis, relational analysis, and word cloud. The analysis identified the emergence and most active discussion periods of XR, with XR devices and manufacturers emerging as key keywords.

Artificial intelligence is one of the key technologies of the Fourth Industrial Revolution. This paper introduces the diverse kinds of approaches to subjects that tackle diverse kinds of research fields such as model-based MS approach, deep neural network model, image edge detection approach, cross-layer optimization model, LSSVM approach, screen design approach, CPU-GPU hybrid approach and so on. The research on Superintelligence and superconnection for IoT and big data is also described such as 'superintelligence-based systems and infrastructures', 'superconnection-based IoT and big data systems', 'analysis of IoT-based data and big data', 'infrastructure design for IoT and big data', 'artificial intelligence applications', and 'superconnection-based IoT devices'.

The purpose of this study was to identify the reasonable gathering conditions as consider of effect of gathering and variation of silhouette made by gathering conditions. The experimental design consists of four factorial design: (1) three kinds of different weight and different thickness fabrics (2) three kinds of different stitch densities (3) five kinds of different ratio of gathers (4) three kinds of different angles. Therefore one hundred thirty five (135) samples were made. Data analysis utilize SPSS WIN 10.0 Package. The results of this study were as follows: 1. In the aspect of fabrics, it is shown the visual propriety that it is as thin as the small stitch, and as thick as the big stitch. 2. As stitch densities, it shows the different stabilized nodes. 3. In the aspect of ratio of gathers, it is shown the visual propriety that a few was small stitches, which help formations of nodes, and a lot were big stitches, which help increased the effect of gather. 4. In the aspect of angle of bias, the drape appearance was excellent as a sample of cutting by 0 angle(0$^{\circ}$) of bias. The big stitches that help formations of stabilized nodes, and a case of cutting by 45 angle(45$^{\circ}$) of bias was small stitch.

The modern large-scale surveys and state-of-the-art cosmological simulations produce various kinds of big data composed of millions and billions of galaxies. Inevitably, we need to adopt modern Big Data platforms to properly handle such large-scale data sets. In my talk, I will briefly introduce the de facto standard of modern Big Data platform, Apache Spark, and present some examples to demonstrate how Apache Spark can be utilized for solving data-driven astronomical problems.

본 논문에서는 자료 조사를 위한 최적의 키워드 추출 및 검색 방법을 제안하였으며, 북한 건설 관련 동향 파악을 예시로 제안 방법을 검증하였다. 대표적인 국내 언론 플랫폼인 빅카인즈(BigKinds)를 활용하여 표본 기사를 선정하고 키워드를 추출하였다. 추출된 키워드는 워드 임베딩(Word Embedding)을 활용하여 벡터화하였으며, 이를 토대로 코사인 유사도(Cosine Similarity)를 통해 추출된 키워드 간의 유사도를 검사하였다. 또한 상위 빈도수 10개에 대한 키워드를 기준으로 유사도 0.5 이상인 키워드들을 군집화하였다. 각 군집들은 빅카인즈 검색 양식에 맞추어 군집 내부 키워드 간에는 'OR', 군집 간에는 'AND'로 형성하였다. 심층 분석 결과, 본래 목적에 맞는 유의미한 기사들이 추출되었음을 확인할 수 있었다. 기존의 분류체계 및 검색 양식을 변형시키지 않은 상태에서 사용자의 세부 목적을 충족시키는 자료 조사·분류가 가능하게 되었다는 점에서 의의를 갖는다.

우리나라 전통적인 수산발효식품의 풍미성분을 밝힐 목적으로 밴댕이젓 및 주둥치젓이 냄새성분을 분석하고 각 성분들이 냄새에 미치는 기여도를 검토하였다. 휘발성 지방산과 휘발성 아민은 수증기증류법으로 포집하여 분석하고, 휘발성 카르보닐은 $90^{\circ}C$에서 4시간 처리하여 포집하여 GLC로 분석동정하였다. 휘발성 지방산은 밴댕이젓 및 주둥치젓 모두 n-부티르산이 $90.4{\sim}90.5%$로 대부분을 차지하였고, 휘발성아민은 트리메틸아민이 대부분을 차지하였다. 휘발성카르보닐은 밴댕이젓은 2-메틸프로판알 36.2%, 메탄알 28.5%, 프로판알 16.2%로 이 세 성분이 80.9%를 차지하였고, 주둥치젓은 에탄올 44.7%, 2-메틸프로판알 24.1%, 프로판알 14.4%로 82.2%를 차지하였다. 관능검사결과 밴댕이젓. 주둥치젓 모두 휘발성지방산, 휘발성카르보닐, 휘발성아민 순으로 중요한 구실을 하는 성분이라는 것을 알았다.

With vigorous development of global network community, smart phones and mobile devices, enterprises can rapidly collect various kinds of data from internal and external environments. How to discover valuable information and transform it into new business opportunities from big data which grow rapidly is an extremely important issue for current enterprises. This study treats Company S as the subject and tries to find the factors of big data application in enterprises by a modified Decision Making Trial and Evaluation Laboratory (DEMATEL) and perceived benefits - perceived barriers relation matrix as reference for big data application and management of managers or marketing personnel in other organizations or related industry.

Taking in a broad sense, the Big Yopae has two kinds of big oval type and chained small squares or big oval type and chained small oval one. These are named as I type and II type. Again, it is divided into of plain oval and of dented one. means that the big and small oval is dented. This study surveyed the Big Yopae according to each ages. They seemed to be created similar times and it is hard to distinguish I-A from II-A type. After that, the big oval varied as dented one and the small oval as well accordingly. Generally, the Big Yopae have rectangle decoration and this showed that the top decoration was influenced by northern culture. It is designated as bird feather style top decoration in this study. The bird feather inserting decoration, which was come from the northern nomadic tribes culture, was started as shamanism to bird and developed into 'Scythe-shaped' tail mode. 'Scythe-shaped' tail mode is considered to have same type with making an application to the bird feather type top decoration.
