Today, due to the 4th industrial revolution and extensive R&D funding, domestic companies have begun to possess world-class industrial technologies and have grown into important assets. The national government has designated it as a "national core technology" in order to protect companies' critical industrial technologies. Particularly, technology leaks in the shipbuilding, display, and semiconductor industries can result in a significant loss of competitiveness not only at the company level but also at the national level. Every year, there are more insider leaks, ransomware attacks, and attempts to steal industrial technology through industrial spy. The stolen industrial technology is then traded covertly on the dark web. In this paper, we propose a system for detecting industrial technology leaks in the dark web environment. The proposed model first builds a database through dark web crawling using information collected from the OSINT environment. Afterwards, keywords for industrial technology leakage are extracted using the KeyBERT model, and signs of industrial technology leakage in the dark web environment are proposed as quantitative figures. Finally, based on the identified industrial technology leakage sites in the dark web environment, the possibility of secondary leakage is detected through the PageRank algorithm. The proposed method accepted for the collection of 27,317 unique dark web domains and the extraction of 15,028 nuclear energy-related keywords from 100 nuclear power patents. 12 dark web sites identified as a result of detecting secondary leaks based on the highest nuclear leak dark web sites.
Recently, as the importance of experience data increases, there are many attempts to deal with experience data from a data science perspective. In the case of approaching as a collection method of a quantitative survey method that seeks to quantify numerically such as big data, it is difficult to interpret the value of experience in a wide range, and it is relatively expensive and time consuming, and personal information infringement There is a limit to the analysis due to the risk of However, since ethnography, a procedure for collecting experience data based on qualitative research, is mainly carried out in the natural real environment of future customers from the perspective of users, it is possible to confirm the nature that customers face with a small sample. In addition, it is also easy to interpret the relational dimension of the empirical data. Although the ethnography method of collecting experiential data is economical and efficient, it is important to reduce errors in the collection process because the lack of scientific procedures for the data collection process can be a problem. It is important to secure the validity of whether the correct measurement tool is used for ethnography-based experiential data collection and to secure the reliability of the use of a valid measurement tool and method by accurately selecting the measurement target. From this point of view, it is necessary to verify the reliability of the research method that clearly selects the measurement target and secures the validity for the development of the correct measurement method and tool for the collection of ethnography experience data. Therefore, in this study, a verification study was conducted on the data and methodology cases of the'I know you_AI' service that analyzes the customer experience of self-employed based on the ethnography method of collecting experience data..

Methods : Studies published from January 2012 to October 2022 in the PubMed, Embase, ScienceDirect, Cochrance Library databases were searched. Keywords used for search were ('developmental coordination disorder' OR 'DCD') AND ('Cognitive Orientation to daily Occupational Performance' OR 'Cognitive Orientation to Occupational Performance' OR 'CO-OP'). Among 211 searched studies, 7 selected studies that match the thesis of this study were analyzed. Results : The selected studies showed a relatively high level of evidence overall, including two randomized experimental studies, one non-random two-group study, three non-random one-group studies, one single-subject study. The self-selected goals preference of the children was high in the order of play, education, and daily life activities. Most of applicable sessions were conducted 10 times during a 1-h period, and intervention effects showed positive outcomes on the occupation performance motor domain. To measure the effectiveness of CO-OP, the improvement of occupational performance was evaluated using Canadian Occupational Performance Measure (COPM) and Performance Quality Rating Scale (PQRS), and the improvement of motor skills was evaluated using Movement Assessment Battery for Children (M-ABC). Conclusion : This study is expected to be used as basic clinical data when applying the CO-OP approach to Developmental Coordination Disorder.
As of the end of 2019, the total population nationwide was 51,849,861, and over the past five years, the population per household has decreased by 1.52% annually from 2.45 in 2015 to 2.31 in 2019. Looking at the current status of population distribution by age group, Busan metropolitan city had the highest proportion of senior citizens aged 65 or older at 18.2%, and Sejong Special Self-Governing city had the lowest at 9.4%. In particular, as of 2019, the population of the mobility handicapped was 15,219,000 nationwide, showing a ratio of about 29.4% of the total population. Therefore, it is important to secure the right to move according to the mobile facilities so that the mobility handicapped can move safely and conveniently. Against this background, this study places value on transportation welfare facilities centered on the mobility handicapped for safe and convenient movement, and in particular, in proposing measures to cope with the entry of an aging society and the continuous increase of the mobility handicapped, the transportation facilities, The purpose of this study is to analyze the impact of welfare facilities on the mobility handicapped and suggest implications.

The aim of this study is to verify the relationships of factors affecting nursing performance of clinical nurses focused on positive affective events. The subjects of this study were 275 clinical nurses from secondary and tertiary general hospitals. Data collection was conducted for two months from May 2021 through an online survey through snowball sampling. Data analyzed was using SPSS 26.0 and AMOS 26.0. The variables affecting job satisfaction included direct effect of positive affective events (β=.65, p<.001), and direct effect of positive affectivity (β=.10, p=.038). Job satisfaction (β=.47, p<.001) had statistically significant direct effects on nursing performance. Positive affective events (β=.32, p=.003) and positive affectivity (β=.05, p=.039) had statistically significant indirect effects on nursing performance. These variables explained for 22% of nursing performance. However, emotional labor had no significant effect on job satisfaction and nursing performance. The results indicate that positive affective events and positive affectivity result in high degree of job satisfaction. Job satisfaction would increase the level of nursing performance. Therefore, in order to improve nursing performance, it is necessary to provide educational opportunities and interventions that can promote positive work environment and positive affectivity.

Due to the nature of electric vehicles, the batteries used for electric vehicles have a very large rated capacity. If an electric vehicle runs for a long time or an electric vehicle is abandoned due to a traffic accident, the electric vehicle battery becomes a waste battery. Even in vehicles that are being abandoned, the remaining capacity of waste batteries for electric vehicles is sufficient for other purposes. Waste batteries for automobiles are very expensive, so they need to be recycled and reused, but there was a problem that the standards for measuring the performance grade of waste batteries for recycling and reuse were insufficient. As a method for measuring the remaining capacity of waste battery, the most stable and reliable method is to measure the remaining capacity of battery using full charge and discharge. However, the inspection method by the full charging and discharging method varies depending on the capacity of the battery, but it takes more than a day to inspect, and many people are making great efforts to solve this problem. In this paper, an electric vehicle battery residual capacity analysis technique using voltage deviation between cells was studied and analyzed as a method to reduce inspection time for electric vehicle batteries. To this end, a full charging and discharging-based capacity measurement system was constructed, experimental data were collected using a nose or waste battery, and the correlation between the voltage deviation and the remaining capacity of the battery pack was analyzed to verify whether it can be used for battery inspection.
Lithium (Li) is a key resource driving the rapid growth of the electric vehicle industry globally, with demand and prices continually on the rise. To address the limited reserves of major lithium sources such as rock and brine, research is underway on seawater Li extraction using electrodialysis and Li-ion selective membranes. Lithium lanthanum titanate (LLTO), an oxide solid electrolyte for all-solid-state batteries, is a promising Li-ion selective membrane. An important factor in enhancing its performance is employing the powder synthesis process. In this study, the LLTO powder is prepared using two synthesis methods: sol-gel reaction (SGR) and solid-state reaction (SSR). Additionally, the powder size and uniformity are compared, which are indices related to membrane performance. X-ray diffraction and scanning electron microscopy are employed for determining characterization, with crystallite size analysis through the full width at half maximum parameter for the powders prepared using the two synthetic methods. The findings reveal that the powder SGR-synthesized powder exhibits smaller and more uniform characteristics (0.68 times smaller crystal size) than its SSR counterpart. This discovery lays the groundwork for optimizing the powder manufacturing process of LLTO membranes, making them more suitable for various applications, including manufacturing high-performance membranes or mass production of membranes.

This study is a scientific approach to psychological factors such as emotional stability among various effects of forest resources. In order to carry out this study, the experiment was conducted on the subjects by setting the forest healing space as various spaces. The subjects who participated in this experiment were the students in their twenties and the average age was 22±1.25 years. The subjects were assessed for emotional words through subjective sequence evaluation in different designated forest healing spot. In addition, the emotional states that they actually perceived were measured by measuring the bio-signals to their perceived emotions. BMP, SDNN, VLF, LF, HF, Amplitude, and PPI were used for the bio-signal reaction experiment applied to this study. The results of this experiment were measured by Friedman test and Wilcoxon test for statistical analysis. n this study, 'good', 'clear', and 'uncomfortable' words were found statistically significant at the spot of forest healing space for subjective emotional vocabulary. In addition, SDNN, HF and Amplitude were statistically significant in the results of quantitative bio-signal measurement at each spot in the forest healing space. Based on the results of this study, we can suggest the application direction and strategic utilization plan of forest healing spot and forest resource utilization field. This is not only a guide for the users who use the facility through the spatial facilities and physical requirements for the emotion based forest-healing, but also can be used as a personalized emotional space design aspect.
The day of the Dead, so called as 'El día de los muertos' in Mexico is the traditional festival of the mexicans. There is no doubt that the origin of the festival traces back to the times of the people of Azteca before the Invasion of the spanish soldiers into the land of the soldiers of Teotihuacán. The festival rituals of the Azteca are the same as the catholic rituals in converging the actual characteristics and the cultural structure of the Festival. Therefore the hybridity of the Festival has been considered as high value worthy to be conserved and named as a world cultural heritage by the UNESCO. This investigation has been realized through the survey of questionnaire to get some practical informations and data on how the mexicans think of the Festival and enjoy it according to the diversity of the believes, sexes, locations, ages, etc. We could reveal that the absolute majority of the mexicans consider the Festival as very positive. Even though the sexes, educations, ages can't be elements to make the differences in conforming the common think of the day of the Dead, believes and locations where the people do live are the most sensitive elements that influence upon the ways of thinking. The protestants think negatively while the catholics do reflect the average opinion of the mexicans who consider the Festival as a good and positive tradition. The people of the city participate less than the people of the provinces. Conclusively the day of the Dead can be considered as a national symbol of the people of Mexico.
