교통사고는 인적요인, 도로 기하구조, 교통류, 환경적 요인 등 복합적인 요인에 의해 발생하고 속도는 교통사고와 밀접한 연관성이 있다. 또한, 교통사고는 교통 혼잡도와 관련이 있으며 사고와 실시간 교통상황 간의 상관관계를 통해 사고 발생 개연성을 추정하고 도 로 안전성 분석이 필요하다. 모바일 센서와 통신 기술의 급속한 발전으로 스마트폰 보급률이 증가하였으며 내장된 센서를 기반으로 생성된 차량 주행 데이터 수집이 가능하다. 기술의 발달로 데이터 수집이 쉬워졌음에도 불구하고, 스마트폰을 기반으로 수집된 위험 운전 이벤트를 활용한 도로 위험도 평가에 대한 연구는 부족한 실정이다. 본 연구는 스마트폰 센서 기반의 위험 운전 이벤트 데이터 중 하나인 급감속 위험 운전 이벤트 데이터를 도로 위험도 평가 기법에 활용하는 것을 목적으로 한다. 급감속 위험 운전 이벤트 데이 터는 주행 차량이 3초간 속도를 40km/h 이상 감소하는 위험 이벤트가 발생할 때 시간과 위치를 기록한 자료를 의미한다. 본 연구의 범위는 대한민국 내 인구와 교통량이 많은 지역인 수도권을 대상으로 서울, 경기, 인천을 연결하는 고리 형태의 도로인 수도권제1순환 선을 대상으로 하였다. 먼저, 개별 차량 데이터는 좌표 기반의 내비게이션 데이터로 집계하여 VDS 링크 데이터와 매칭하였다. 다음으 로는 개별 차량의 위험 운전 이벤트 데이터와 차량 검지기의 교통 매개변수를 결합한 새로운 지표를 개발하였다. 또한, 시·공간적 교 통류의 특성을 반영하여 다양한 도로 위험도 평가 방법에 활용하고자 하였다. 마지막으로 위험 운전 지표와 이력 자료를 기반으로 통 계적으로 유의한 안전성능함수를 개발하였으며, 다양한 시간 단위의 집계 수준을 활용하여 도로 구간별 최적의 모형을 제안하였다. 본 연구는 스마트폰 센서를 기반으로 식별한 개별 차량의 위험과 교통류 차원의 위험을 결합하여 새로운 위험 지표를 개발하고 도로 위 험도 평가에 활용한다는 것에 의의가 있다. 결과물은 향후 스마트폰 센서 기반 개별 차량 위험 운전 이벤트 데이터와 교통 조건을 통 합하는 도로 위험도 평가의 기초자료로써 활용될 것으로 기대된다.

This study utilizes social big data to investigate the factors influencing the awareness, attitude, and behavior toward vegan fashion consumption among global and Korean consumers. Social media posts containing the keyword “vegan fashion” were gathered, and meaningful discourse patterns were identified using semantic network analysis and sentiment analysis. The study revealed that diverse factors guide the purchase of vegan fashion products within global consumer groups, while among Korean consumers, the predominant discourse involved the concepts of veganism and ethics, indicating a heightened awareness of vegan fashion. The research then delved into the factors underpinning awareness (comprehension of animal exploitation, environmental concerns, and alternative materials), attitudes (both positive and negative), and behaviors (exploration, rejection, advocacy, purchase decisions, recommendations, utilization, and disposal). Global consumers placed great significance on product-related information, whereas Korean consumers prioritized ethical integrity and reasonable pricing. In addition, environmental issues stemming from synthetic fibers emerged as a significant factor influencing the awareness, attitude, and behavior regarding vegan fashion consumption. Further, this study confirmed the potential presence of cultural disparities influencing overall awareness, attitude, and behavior concerning the acceptance of vegan fashion, and offers insights into vegan fashion marketing strategies tailored to specific cultures, aiming to provide vegan fashion companies and brands with a deeper understanding of their consumer base.

빠르게 발전하는 이미지 인식 기술에도 불구하고 표 형식의 문서와 수기로 작성된 문서를 완벽하게 디지털화하기에는 아직 어려움이 따른다. 본 연구는 표 형식의 수기 문서인 선박 항해일지를 작성하는 데에 사용되는 규칙을 이용하여 보정 작업을 수행함으로 써 OCR 결과물의 정확도를 향상시키고자 한다. 이를 통해 OCR 프로그램을 통하여 추출된 항해일지 데이터의 정확성과 신뢰성을 높일 것 으로 기대된다. 본 연구는 목포해양대학교 실습선 새누리호의 2023년에 항해한 57일간의 항해일지 데이터를 대상으로 OCR 프로그램 인 식 후 발생한 오류를 보정하여 그 정확도를 개선하고자 하였다. 이 모델은 항해일지 기재 시 고려되는 몇 가지 규칙을 활용하여 오류를 식별한 후, 식별된 오류를 보정하는 방식으로 구성하였다. 모델을 활용하여 오류를 보정 후, 그 효과를 평가하고자 보정 전과 후의 데이터 를 항차별로 구분한 후, 같은 항차의 같은 변수끼리 비교하였다. 본 모델을 활용하여 실제 셀 오류율은 약 11.8% 중 약 10.6%의 오류를 식 별하였고, 123개의 오류 중 56개를 개선하였다. 본 연구는 항해일지 중 항해정보를 기입하는 Dist.Run부터 Stand Course까지의 정보만을 대 상으로 수행하였다는 한계점이 있으므로, 추후 항해정보 뿐만 아니라 기상정보 등 항해일지의 더 많은 정보를 보정하기 위한 연구를 진 행할 예정이다.

The Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer (SPHEREx) will provide all-sky spectral survey data covering optical to mid-infrared wavelengths with a spatial resolution of 6.′′2, which can be widely used to study galaxy formation and evolution. We investigate the galaxy-galaxy blending in SPHEREx datasets using the mock galaxy catalogs generated from cosmological simulations and observational data. Only ∼0.7% of the galaxies will be blended with other galaxies in all-sky survey data with a limiting magnitude of 19 AB mag. However, the fraction of blended galaxies dramatically increases to ∼7–9% in the deep survey area around the ecliptic poles, where the depth reaches ∼22 AB mag. We examine the impact of the blending in the number count and luminosity function analyses using the SPHEREx data. We find that the number count can be overestimated by up to 10–20% in the deep regions due to the flux boosting, suggesting that the impact of galaxy-galaxy blending on the number count is moderate. However, galaxy-galaxy blending can marginally change the luminosity function by up to 50% over a wide range of redshifts. As we only employ the magnitude limit at Ks-band for the source detection, the blending fractions determined in this study should be regarded as lower limits.

Laurencia is a red algal genus that was described by J.V. Lamouroux in 1813. The main characteristics of this genus have been known as the presence of four pericentral cells in an axial segment, secondary pit connections between adjacent epidermal cells, and the presence of corps en cerise in both epidermal and trichoblast cells. Additionally, the tetrasporangia are arranged in a parallel manner, and male branches feature terminal cup-shaped spermatangial pits. Currently, sixteen Korean Laurencia species have been reported based on their morphological characteristics. In this study, Laurencia decussata and L. pacifica have been added as new records to the Korean algal flora based on a combination of morphological observations and molecular analyses of rbcL sequences. Laurencia decussata has expanded from Australia and New Zealand to Korea, while the distribution of L. pacifica has expanded from USA and Mexico to Korea.

Truck no-show behavior has posed significant disruptions to the planning and execution of port operations. By delving into the key factors that contribute to truck appointment no-shows and proactively predicting such behavior, it becomes possible to make preemptive adjustments to port operation plans, thereby enhancing overall operational efficiency. Considering the data imbalance and the impact of accuracy for each decision tree on the performance of the random forest model, a model based on the Borderline Synthetic Minority Over-Sampling Technique and Weighted Random Forest (BSMOTE-WRF) is proposed to predict truck appointment no-shows and explore the relationship between truck appointment no-shows and factors such as weather conditions, appointment time slot, the number of truck appointments, and traffic conditions. In order to illustrate the effectiveness of the proposed model, the experiments were conducted with the available dataset from the Tianjin Port Second Container Terminal. It is demonstrated that the prediction accuracy of BSMOTE-WRF model is improved by 4%-5% compared with logistic regression, random forest, and support vector machines. Importance ranking of factors affecting truck no-show indicate that (1) The number of truck appointments during specific time slots have the highest impact on truck no-show behavior, and the congestion coefficient has the secondhighest impact on truck no-show behavior and its influence is also significant; (2) Compared to the number of truck appointments and congestion coefficient, the impact of severe weather on truck no-show behavior is relatively low, but it still has some influence; (3) Although the impact of appointment time slots is lower than other influencing factors, the influence of specific time slots on truck no-show behavior should not be overlooked. The BSMOTE-WRF model effectively analyzes the influencing factors and predicts truck no-show behavior in appointment-based systems.

In this study, we propose a novel approach to analyze big data related to patents in the field of smart factories, utilizing the Latent Dirichlet Allocation (LDA) topic modeling method and the generative artificial intelligence technology, ChatGPT. Our method includes extracting valuable insights from a large data-set of associated patents using LDA to identify latent topics and their corresponding patent documents. Additionally, we validate the suitability of the topics generated using generative AI technology and review the results with domain experts. We also employ the powerful big data analysis tool, KNIME, to preprocess and visualize the patent data, facilitating a better understanding of the global patent landscape and enabling a comparative analysis with the domestic patent environment. In order to explore quantitative and qualitative comparative advantages at this juncture, we have selected six indicators for conducting a quantitative analysis. Consequently, our approach allows us to explore the distinctive characteristics and investment directions of individual countries in the context of research and development and commercialization, based on a global-scale patent analysis in the field of smart factories. We anticipate that our findings, based on the analysis of global patent data in the field of smart factories, will serve as vital guidance for determining individual countries' directions in research and development investment. Furthermore, we propose a novel utilization of GhatGPT as a tool for validating the suitability of selected topics for policy makers who must choose topics across various scientific and technological domains.

This study was conducted to investigate whether there were differences in eco-friendly food, home meal replacement (HMR) purchases, and eating-out behavior according to the level of agri-food consumer competence. The data for the study were extracted from main food consumers (n=3,321) in the 2022 Food Consumption Behavior Survey. The competence index was divided into awareness-attitude-practice items, and three groups were classified by competence level. The results showed an agri-food consumer competency score of 70.62, with the highest score for awareness (73.96), followed by practice (69.28) and attitude (66.18). The frequency of purchasing eco-friendly food was higher in the excellent group compared to other groups, and quality and price satisfaction was higher with higher competency (p<0.001). Regarding HMR, the results showed that the shortage group had the lowest HMR consumption rate, and satisfaction decreased as competence decreased (p<0.001). The main reason for eating-out was to enjoy food in all groups (59.0%), followed by a lack of cooking time in the excellent group (15.7%) and hassle with food preparation in the moderate and shortage groups (17.3%, 16.6%) (p<0.001). In short, agri-food consumption competency showed differences by contents and components, and differences in food purchases and eating-out behavior by competency level were found.

본 연구에서는 레이더 관측 영역 내에 강수 에코(echo)가 없는 지역을 비강수 정보라고 정의하고 자료 동화에 활용하였다. 비강수 정보는 레이더로 관측할 수 있는 최대 영역 내에서 강수에 의한 에코가 나타나지 않고 레이더에서 관측할 수 없을 정도로 약한 강수나 구름 입자가 있거나, 강수 자체가 없다는 것을 의미한다. 기존의 레이더 자료를 동 화한 연구가 강수에 의한 반사도와 시선속도를 동화하여 모델 내의 강수를 만들어내는 것에 초점을 두었다면, 본 연구 에서는 에코가 없다는 것도 하나의 정보로 고려하고 이를 동화함으로써 모델 내에서 잘못 예측한 강수를 억제하였다. 비강수 정보를 자료동화에 적용시키기 위해 레이더 비강수 정보를 수상체와 상대습도로 변환하는 관측 연산자를 제시 하고 이를 Weather Research and Forecasting (WRF) 모델의 자료동화 시스템인 WRF Data Assimilation system (WRFDA)에 적용하였다. 또한 비강수 정보를 효과적으로 활용하기 위한 레이더 자료의 처리 방법을 제시하였다. 비강 수 정보가 모델 내에서 잘못 예측한 강수를 억제할 수 있는지 확인하기 위해 단일 관측실험을 수행하였으며 비강수 정 보가 수상체와 습도 그리고 기온을 낮춤으로써 대류가 억제될 수 있는 환경을 만들었다. 비강수 정보의 동화 효과를 실제 사례에 적용한 2013년 7월 23일 대류 사례 실험을 통해 9시간 예측을 수행하여 결과를 분석하였다. 레이더 비강 수 정보를 추가로 동화한 실험이 비강수 정보를 제외한 실험보다 Fractional Skill Score (FSS)가 증가하고 False Alarm Ratio (FAR)는 감소하여 모델의 강수 예측성을 향상시켰다.

Currently, there is no definitive regulation for the appropriate frequency of data sampling in water distribution networks, yet it plays a crucial role in the efficient operation of these systems. This study proposes a new methodology for determining the optimal frequency of data acquisition in water distribution networks. Based on the decomposition of signals using harmonic series, this methodology has been validated using actual data from water distribution networks. By analyzing 12 types of data collected from two points, it was demonstrated that utilizing the factors and cumulative periodograms of harmonic series enables similar accuracy at lower data acquisition frequencies compared to the original signals.

The limitation in deriving the species richness representing the entire country of South Korea lies in its relatively short history of species field observations and the scattered observation data, which has been collected by various organizations in different fields. In this study, a comprehensive compilation of the observation data for plants held by agencies under the Ministry of Environment was conducted, enabling the construction of a time series dataset spanning over 100 years. The data integration was carried out using minimal criteria such as species name, observed location, and time (year) followed by data verification and correction processes. Based on the integrated plant species data, the comprehensive collection of plant species in South Korea has occurred predominantly since 2000, and the number of plant species explored through these surveys appears to be converging recently. The collection of species survey data necessary for deriving national-level biodiversity information has recently begun to meet the necessary conditions. Applying the Chao 2 method, the species richness of indigenous plants estimated at 3,182.6 for the 70-year period since 1951. A minimum cumulative period of 7 years is required for this estimation. This plant species richness from this study can be a baseline to study future changes in species richness in South Korea. Moreover, the integrated data with the estimation method for species richness used in this study appears to be applicable to derive regional biodiversity indices such as for local government units as well.

The genus Desmodesmus (Chodat) S.S. An, T. Friedl & E. Hegewald is ubiquitous in freshwater ecosystems, such as rivers, ponds, and wetlands. The actual species diversity and distribution of the genus is unknown because of morphological plasticity affected by habitats. Currently, 38 Desmodesmus species have been reported in Korea most of which transferred from the genus Scenedesmus recently, however, no phylogenetic relationships have been studied yet. Despite the challenges in analyzing relationships among Desmodesmus species through the morphology, ecology, and original description, this study focused on examining species-level relationships using the FBCC culture strains isolated from Korea. A total of 299 sequences (66 of 18S rRNA, 47 of atpB, 67 of petA, 52 of rbcL, and 67 of tufA) were newly determined and used for phylogenetic analysis. Four plastid genes tend to have higher variation than 18S rRNA in the variable sites and P-distance. From the combined phylogeny, the Desmodesmus included six clades such as Clade-1: D. pseudoserratus and D. serratus, Clade-2: D. communis, D. dispar, D. maximus, D. pannonicus, unidentified Desmodesmus sp., Clade-3: D. bicaudatus and D. intermedius, Clade-4: D. microspina, D. multivariablis, D. pleiomorphus, D. subspicatus, Clade-5: D. abundans, D. kissii, and D. spinosus, and Clade-6: D. armatus, D. armatus var. longispina, D. opoliensis, unidentified Desmodesmus spp. The new sequence data from FBCC strains will be used to identify species and study the molecular ecology of scenedesmacean green algae in freshwater ecosystems. The phylogenetic information from this study will expand our understanding of Desmodesmus species diversity in Korea.

PURPOSES : This study aims to perform a quantitative analysis of Forward Collision Warning and crash frequency using heavy vehicle driving data collected in expressway driving environments, and to classify the driving environments where Forward Collision Warnings of heavy vehicles occur for accident-prone areas and analyze their occurrence characteristics. METHODS : A bivariate Gaussian mixture model based on inter-vehicle distance gap and speed-acceleration parameters is used to classify the environment in which Forward Collision Warning occurs for heavy vehicles driving on expressways. For this analysis, Probe Vehicle Data of 80 large trucks collected by C-ITS devices of Korea Expressway Corporation from May to June 2022. Combined with accident information from the past five years, a detailed analysis of the classified driving environments is conducted. RESULTS : The results of the clustering analysis categorizes Forward Collision Warning environments into three groups: Group I (highdensity, high-speed), Group II (high-density, low-speed), and Group III (low-density, high-speed). It reveals a positive correlation between Forward Collision Warning frequency and accident rates at these points, with Group I prevailing. Road characteristics at sites with different accident incidences showed that on-ramps and toll gates had high occurrences of both accidents and warnings. Furthermore, acceleration deviation at high-accident sites was significant across all groups, with variable speed deviations noted for each warning group. CONCLUSIONS : The Forward Collision Warning of heavy vehicles on expressways is classified into three types depending on the driving environment, and the results of these environmental classifications can be used as a basis for building a road environment that reduces the risk of crashes for heavy vehicles.

2015년부터 2022년도까지 6개목(딱정벌레목, 노린재목, 나비목, 벌목, 파리목, 총채벌레목) 곤충들에 대해서 식물검역현장 검출실적과 국내 보고된 미기록종을 분석하였다. 해당기간 동안 국경검역에서 6개목 곤충은 총 45,084건이 검출되었다. 같은 기간 국내에서는 총 545종이 미기록종 으로 보고되었으며, 이중 9종은 국경검역에서도 검출된 것으로 확인되었다. 검역현장에서는 딱정벌레목, 총채벌레목, 노린재목이 높은 검출률을 보 였으며, 국내 미기록종 중에서는 벌목이 176종으로 가장 많이 보고되었다. 본 연구를 통해 침입압력(국경검역 검출)과 실제 침입(국내 미기록종 발 견) 사이에 비동시성이 확인되었다. 향후 보다 장기적인 분석이 필요할 뿐만 아니라 지속적인 식물검역시스템 개선이 필요할 것으로 판단된다.

PURPOSES : This study aims to understand the characteristics of accidents involving autonomous vehicles and derive the causes of accidents from road spatial information through autonomous vehicle accident reports. METHODS : For this study, autonomous vehicle accident reports collected and managed by the CA DMV were used as data sources. In addition, spatial characteristics and geometric data for accident locations were extracted by Google maps. Based on the collected data, the study conducted general statistics, text embedding, and cross-analysis to understand the overall characteristics of autonomous vehicle accidents and their relationship with road spatial features. RESULTS : The analysis results for characteristics of autonomous vehicle accidents, applying statistical analysis and text embedding techniques, reveal that the damages caused by autonomous vehicle accidents are often minor, and approximately half of the accidents are triggered by other vehicles. It is noteworthy that accidents where autonomous vehicles are at fault are not uncommon, and when the cause of the accident is within the autonomous vehicle, the accident risk can increase. The accident analysis results using spatial data showed that the severity of accidents increases when on-street parking is present, when dedicated lanes for bicycles and buses exist, and when bus stops are present. CONCLUSIONS : Through this study, geometric and spatial elements that appear to have an impact on autonomous driving systems have been identified. The findings of this study are expected to serve as foundational data for improving the safety of autonomous vehicle operations in the future.

Purpose: Even today, cancer remains a challenge to overcome. The purpose of this study is to understand the current status of lip-oral-pharyngeal cancer in Koreans by identifying the survival rate of lip-oral-pharyngeal cancer in Koreans through long-term big data. Material and Method: This study utilized 2023 KOSIS (Cancer Registration Statistics, Ministry of Health and Welfare) academically. The 5-year relative survival rates of lip-oral-pharyngeal cancer from 1996 to 2020 were compared and analyzed at 5-year intervals. Results: The 5-year relative survival rate for lip-oral-pharyngeal cancer was 47.4% from 1996 to 2000, 54.5% from 2001 to 2005, 61.1% from 2006 to 2010, 65.5% from 2011 to 2015, and 69.7% from 2016 to 2020. From 1996 to 2005, the 5-year relative survival rate for lip-oral-pharyngeal cancer was higher than the 5-year relative survival rate for all cancers. However, in the recent 15 years from 2006 to 2020, the 5-year relative survival rate for lip-oral-pharyngeal cancer was lower than for all cancers. Conclusions: In conclusion, this long-term big data showed that the 5-year relative survival rate of lip-oral-pharyngeal cancer in Koreans has increased further in modern times. However, in order to increase the overall survival rate of all human cancers, continuous efforts to improve the survival rate of lip-oral-pharyngeal cancer are needed in the future.

In this study, quantitative analysis is attempted on data collected from Chilgapsan Observatory Star Park in Cheongyang-gun, Chungcheongnam-do. The aim of this experimental study in which quantitative analysis of the Astronomical Science Museum in Korea is conducted is to investigate its current situation and secure basic data. As of July 31, 2023, it has had 283,931 cumulative visitors in total. It had the largest number of visitors when it opened (2009 year), after which their number reduced steadily until the pandemic (COVID-19, 2020–2022). Recently, however, the number of visitors has increased. Generally, the number of visitors is highest in August (20.8$\%$) and least in April (4.1$\%$). The visit rate is higher on weekends (Saturday and Sunday) than on weekdays (Monday–Friday), and groups comprise only about 5.3$\%$ of the total number of visitors. Moreover, it can be confirmed that the number of visitors increases sharply during events. Finally, it was confirmed that the visit rate was unaffected by weather conditions. Considering these results, we propose the following strategies: 1) Establish a special program that reflects “the weekend effect.” 2) Prepare a plan to attract group visitors during the weekdays using “the event effect.” 3) Arrange alternative programs (e.g., experiential activities) that can be conducted indoors regardless of weather conditions. We think that our findings will help establish a roadmap for the direction the Astronomical Science Museum should take and aid in preparing a strategic foundation to preemptively respond to unexpected situations (e.g., pandemics).

본고는 단국대학교 부설 한문교육연구소에서 개발 중인 특수 어휘 매칭 툴을 구동시켜 어휘 데이터의 문제점과 개선 방향을 논의하기 위해 작성되었다. 한문교육연구소 개발 어휘 매칭 툴은 최종적으로 한문 고전 텍스트를 토크나이징(Tokenizing) 하기 위한 것이며, 특수 어휘의 매칭은 전체 텍스트를 토크나이징을 하기 위한 첫 단계라고 할 수 있다. 이 어휘 매칭 툴 실행 결과를 MARKUS 자동 마크업과 비교함으로써 매칭 툴과 그 데이터의 장단점을 분석하고, 이 과정에 발견된 문제점에 대해 보완할 수 있는 방향을 제시하였다. 한문교육연구소 어휘 매칭 툴은 한문고전에 특화된 도구로서 중요한 역할을 할 수 있으며, 앞으로 한문 고전의 토크나이징 에도 기여할 것으로 기대된다. 하지만 현재 상태에서는 여러 가지 보완이 필요하다. 우선, 한국 고유의 지명과 인명 데이터를 추가할 필요가 있다. 현재 데이터는 주로 중국의 어휘에 집중되어 있어 한국 고유 어휘가 부족한 상황이다. 추가 어휘데이터를 구축함으로써 해결할 수 있을 것으 로 보인다. 또 별칭의 매칭 문제 등을 해결할 필요가 있다.
