The choice of lashing material is considered to be one of the important decision-making matters in securing the stability of cargo and ships in a situation where in-ship cargo must be tied by cargo and unit and fixed to the ship. This study focused on examining the breaking strength of woven lashing in use at the lashing work site and confirming safety through a comparison of related technical standards. As a result of the experiment, the minimum system fracture strength required according to the manufacturer's specifications was 8,500 daN/(18,700 lbf), and the experimental results averaged 9,012 daN(20,259 lbf), indicating that it met the criteria. In addition, the average actual elongation at maximum fixed loads (MSL: 4,620 daN(10,164 lbf)) was 5.9%, which met the criteria specified in CTU Code Appendix 7(MSC.1/Circ.1497). Applying woven lashing to coil lashing work in ships, lashing material costs were reduced by an average of 25% for the same workload during coil lashing work, the lashing time was shortened, resulting in an average reduction of 10% in ship mooring time.

The purpose of this study was to optimize the design of asphalt concrete pavements for Jeju Island by considering the regional characteristics of the island. This study employed an MEPDG program to determine the allowable traffic loads for class 4 vehicles by considering the axle loads, climate, and material properties. Samples of basalt asphalt concrete from Jeju were used to measure the dynamic modulus for material property estimation. The climate input was based on 30-year climate data from Jeju. The thicknesses and moduli of the subgrade, subbase, and asphalt layers were incorporated into the design. The regression-analysis program SPSS was used to develop a regression equation for the overlay design, factoring in the modulus and thickness ratios between the existing and overlay asphalt layers. A pavement-thickness design formula tailored to Jeju's characteristics was derived. An equivalent single-axle load factor (ESALF) formula was developed to facilitate traffic-load estimation for different roads, enabling the easy incorporation of varying traffic volumes into the design. The ESALF formula demonstrated a high correlation with the pavement thickness, subgrade conditions, and axle loads, whereas the pavementthickness design formula exhibited strong correlations with the pavement thickness, subgrade state, thickness ratios, and modulus ratios. The use of basalt aggregates in asphalt concrete pavements provides an economically viable and technically sound solution for Jeju. The proposed design methodology not only reduces costs but also enhances pavement performance and road safety. The developed formulas offer flexibility in adjusting designs based on specific traffic conditions, providing optimal pavement solutions for different road categories.

PURPOSES : This study was conducted to prevent slip accidents on manhole covers located on sidewalks and local roads as well as to propose reasonable slip resistance management standards for manhole covers. METHODS : Using field surveys, test groups were classified based on the patterns and wear amounts of the manhole covers. Standards for measuring the equipment and methods for slip resistance were established, and the slip resistance values were compared and analyzed for each manhole cover test group. RESULTS : According to the slip resistance test results, micro-protrusions on the non-slip manhole covers were found to be effective in improving slip resistance. However, in areas without microprotrusions, the improvement in slip resistance was minimal and yielded results similar to those of standard manhole covers. In addition, among the pattern types of standard manhole covers, the radial pattern was found to be the most susceptible to slipping. Under the current wear measurement standards, the change in slip resistance at different wear stages was found to be relatively small. Moreover, manhole covers had the lowest slip resistance among road surface structures, indicating the need to establish management standards for them. CONCLUSIONS : To prevent pedestrian slip accidents on sidewalks and local roads, it is necessary to ensure that the slip resistance standards of manhole covers are higher than those of sidewalks.

건축물에 가해지는 풍하중을 평가하는 방법은 과거로부터 많은 발전을 이루었다. 그 중 비교적 간단한 방법인 가스트하중계 수법이 있다. 정적풍하중에 동적계수를 곱하여 등가정적풍하중을 평가하는 방법으로 여러나라 기준에서 사용되고 있다. 동적계수는 가 스트영향계수(Gust Effect Factor:DGEF)와 가스트하중계수가(Gust Loading Factor:MGLF)가 사용된다. DGEF는 변위 기반으로서 이론 적인 가정을 통해 산출할 수 있는 반면 그 과정이 다소 복잡하고, MGLF는 모멘트를 기반으로 하며 풍동실험으로 전도모멘트를 측정 하여 산정할 수 있지만 기초자료를 구축하는 것에 많은 시간과 노력이 소요된다. 따라서 본 연구에서는 MGLF 산정 시 필요한 풍방향 평균풍력계수C F, 평균전도모멘트계수C M, 변동전도모멘트계수 C M 가 다양한 형상비( ), 변장비(D/B), 지표면조도구분(α)에 따 라 변화하는 경향을 비교 분석하였다. 이를 통해 풍방향 평균풍력계수 C F, 평균전도모멘트 관련 계수 C g, 변동전도모멘트 관련 계수 C g 의 경험식을 제안하여 MGLF 산정에 대한 기초자료를 제시하였다.

This research aims to validate the effectiveness of the "Specialized Entrepreneurship University Program," which was conducted as part of government entrepreneurship support initiatives from 2018 to 2022. Based on previous studies, a research model was derived consisting of three laboratory entrepreneurship support factors that influence program satisfaction and entrepreneurial outcomes (infrastructure support, educational mentoring support, and business linkage support). Surveys were collected and analyzed from 126 laboratory entrepreneurship firms participating in the program, and empirical analysis of the research model was conducted using SPSS 23.0 statistical software. The analysis results indicated that the three variables, namely infrastructure support, educational mentoring support, and business linkage support, were significant factors affecting program satisfaction, and program satisfaction was confirmed to influence entrepreneurial outcomes. Furthermore, it was found that the three business operation factors indirectly influenced entrepreneurial outcomes by partially mediating program satisfaction. This study is considered significant as an empirical study for the initial stage of the second-phase program enhancement, verifying the effectiveness of laboratory entrepreneurship support factors. The findings can be applied to similar government entrepreneurship support initiatives and contribute to the effective strategy and planning of stakeholders involved. The limitations of this study include the need for further research on the perception of the extent to which it contributes to entrepreneurial outcomes, emphasizing caution in interpreting the research model, and the necessity for expanding the survey population and improving survey items in future research.

In order to communicate brand concepts and values to the young generations, many brands are highly active on social media platforms such as Twitter, Facebook, and Instagram. Brand-Generated Content has already become the most common marketing strategy for fashion brands and plays a significant role in influencing consumers’ purchase intention. With increased competition on social media platforms, companies need to understand which posting features can bring in more consumer engagements such as number of likes and comments on social media platforms. In this paper, we develop (1) a model to predict the number of likes and (2) a methodology to detect anomaly of posts that have unusually high percentage of negative user comments based on Instagram design variables, including semantic text meanings, facial expressions, color scheme and background of photos, and post timing, among others. We collected a data set of brand-generated Instagram posts from ten fashion brands. The data covers the image, text, and user comments posted between 2019 and 2020. Image features were extracted using Convolutional Neural Network, and text topics were generated through Latent Dirichlet Allocation. Our results will help managers design Instagram posts to increase consumer engagement and to reduce negative consumer reactions.

In recent years, advances in the digital and live streaming economy have led to exponential growth in the number of self-employed streamers who have become an integral part of the self-driven digital labor force. However, previous research on the impact of streamers' work time arrangements on their virtual gifts remains scarce. To fill this gap in the literature, using large-scale data from Kuaishou live streaming platform, we demonstrate that several features of streamers' work time have an important impact on their virtual gifts. Specifically, our results suggest that work time duration and timing improve streamers' virtual gifts; meanwhile, work time tempo has an adverse effect on streamers' earnings. Taken together, our results provide novel and actionable insights for millions of self-employed streamers, agencies, platforms, and policymakers.

Manufacturing process mining performs various data analyzes of performance on event logs that record production. That is, it analyzes the event log data accumulated in the information system and extracts useful information necessary for business execution. Process data analysis by process mining analyzes actual data extracted from manufacturing execution systems (MES) to enable accurate manufacturing process analysis. In order to continuously manage and improve manufacturing and manufacturing processes, there is a need to structure, monitor and analyze the processes, but there is a lack of suitable technology to use. The purpose of this research is to propose a manufacturing process analysis method using process mining and to establish a manufacturing process mining system by analyzing empirical data. In this research, the manufacturing process was analyzed by process mining technology using transaction data extracted from MES. A relationship model of the manufacturing process and equipment was derived, and various performance analyzes were performed on the derived process model from the viewpoint of work, equipment, and time. The results of this analysis are highly effective in shortening process lead times (bottleneck analysis, time analysis), improving productivity (throughput analysis), and reducing costs (equipment analysis).

In recent years, ESG activities (Environment, Social and Governance) have been paid more and more attention by enterprises and their stakeholders in various countries. China is the largest developing country in the world. The ESG performance of Chinese listed enterprises helps to understand the shortcomings of their sustainable development ability and further enhance the firm value. Moreover, the interaction effect between green innovation investment and ESG activities is of great significance for enterprises to balance the resource allocation between the two factors in the future. Taking listed Chinese manufacturing companies from 2011 to 2020 as an example, this study investigates the influence of ESG activities on financial performance and non-financial performance, and tests the moderating role of green innovation. Our results show that: (1) ESG performance has a negative impact on financial performance; (2) ESG performance has a positive impact on non-financial performance; (3) Green innovation can positively adjust the negative impact of environmental activities on financial performance. However, it will enhance the negative impact of governance activities on financial performance. The interaction effect between green innovation and social activities on corporate financial performance is a substitution effect; (4) With the improvement of green innovation level, the positive impact of ESG overall performance and environmental performance on corporate reputation will also be suppressed.
