The purpose of this study is to investigate the relationship between cognitive levels and achievement of science process skills. A science laboratory process skills test based on optional instrument of the SISS was administered to a sample of 162 students in the 8th grade. Practical assessment tasks consisted of the contents about acid, base, density, and a property of cobalt chloride. The format of this practical test was the station type that students had to conduct a short activity. Science process skills included three sub-skills which were categorized as designing, performing, and reasoning. As cognitive levels develop from concrete operational stage to transition stage and formal operational stage. total scores of science process skills and mean scores of sub-skills were significantly increased. Regardless of cognitive levels. all students were more successful on performing than designing or reasoning. In case of being controlled cognitive levels, gender differences and area differences were not detected in achievement of science process skills. According to these results. there was a strong relationship between cognitive levels and achievement of science process skills by practical assessment. This study implies that considering student's cognitive levels is very important for improving science process skills.

Patent information describes the history of technological progress in the relevant field, so it can be usefully used to identify trends in technological development and change and to establish R&D development strategies. This study proposes a method to identify the needs and problems of technology development at the planning stage of the R&D process and to analyze core technologies through patent analysis using Natural Language Processing(NLP) technology. As a big data source, collected patent documents registered in Google Patents for foldable technology, the latest technology in the display industry, and then extracted keywords using NLP analyzer. By classifying the extracted keywords into needs and problems for technology development, developed technology and materials, identified the needs of the market and customers and analyzed the technologies being researched and developed. Unlike previous studies that performed patent analysis, this methodology is different in that it can quickly and conveniently analyze the latest technology trends from big data called patents even if you do not have specialized knowledge and skills in the text mining. This study contributes to the digitalization of the R&D process based on data analysis.

This study aims to cultivate specialized professionals equipped with practical skills essential for compliance with textile environmental regulations and analysis of harmful substances. This is achieved through the revision and restructuring of educational programs targeting workers in the chemical analysis industry. To address this, a survey was conducted among chemical industry workers in small and medium-sized enterprises (SMEs) to gauge the demand for educational programs. Specifically, a survey was conducted among 240 SME workers who participated in the 2022 education curriculum to identify their educational needs and specific requirements in the field. The research findings indicate that the majority of SMEs recognize the necessity of education in the chemical field and express a strong willingness to engage in the curriculum. Particularly emphasized was the need to enhance practical skills crucial for compliance with chemical environmental regulations. Consequently, adjustments were made to the curriculum, reallocating time and increasing the duration of practical training. This enables trainees to directly operate analysis machines and interpret results. Additionally, in response to further educational demands reflected by survey participants, the curriculum was expanded from five to six courses, with adjustments made to existing educational programs. Based on these research outcomes, practical educational methods tailored to SME requirements are proposed, aiming to bridge the gap between regulatory compliance and industry needs.
