This paper is an experience and observation report on the activities of Jeonju citizens, who are 'kleine leutes'. Text or Born-digital materials such as diaries, group chat rooms, memos, and interviews showing citizens' contemporary and daily history (Alltagsgeschichite) were used for this purpose. These civic groups are reading groups we can find easily and they also enjoy walking, hiking, and movies, and so to speak ordinary local people are their members. One team read Choi Myung-hee's "Honbul" for about a year and a half, while another team read several books under the theme of "commons," and enjoyed exploring, exhibiting, or watching movies together. The main text is composed of three parts. First, I looked at the methods and perspectives to examine the daily life of local people. To this end, the views of Detlev Peukert and Alf Lüdtke, who captured the prospects and the possibilities of theories of daily history, and James C. Scott, who provided insight into infra-politics, were reviewed. This work was to find the perspective and method of daily history research that could observe the activities of Jeonju citizens. Second, we looked at the experience of the "Honbool" meeting. The reading of "Honbool" which took place during the period of confrontation with Covid19 began in connection with its intense locality. As the criticism of "a great writer born in our local land" relieved the uncomfortable feelings, the members' critical mind was revealed after Volume3 of "Honbool" and stood out after Volume6. It seemed to show the characteristics of the self-consciousness (Eigensinn) of citizens who choose dynamics rather than being stuck to a specific form of empathy (Betroffenheit). I think it showed the difficulty and hope to face in the description and research of local history at the same time. Third, I observed citizens who gathered on the subject of public land. This meeting showed the actuality and accumulation process of the infra-political capabilities of citizens in Jeonju. Reading-commons did not suffer from 'heart trouble' as a local citizen compared to "Honbool". Rather, the difficulty of related books was an obstacle, and the difficulty was easily resolved. As the meeting progressed, awareness of the commons became more sophisticated and issues and discussions were independently shared with each other, and a wealth of hidden transcripts were accumulated through its practice and problem consciousness. It is difficult to think about modern daily life apart from the capitalist era. More fundamentally, it is here and now in everyday life that humans enjoy or suffer from. All history passes through my body here and now. This is the universality of daily history. It depends on the ability of citizens to create daily history to experience and at the same time maintain the distance of criticism.

The purpose of this study is to identify the sub-factors of consultant ability of an industrial safety consulting company and conduct an empirical study on how these factors influence the intention to recontract by mediating consulting satisfaction and utilization Research on consultant ability, satisfaction with and utilization of consulting has been actively conducted in fields such as small and medium-sized business consulting and management consulting, but research in the field of industrial safety consulting has been found to be insufficient. Accordingly, this study seeks to demonstrate the causal relationship between the ability of industrial safety consultants, satisfaction and utilization of consulting, and recontract intention. Using the random sampling method, the researcher collected 202 questionnaires from customers such as companies and public institutions receiving industrial safety consulting, and conducted statistical analysis with the SPSS 21.0 program. The results of the study were as follows. First, it was found that consultant ability, consultant knowledge, and consultant attitude, which are sub-factors of consultant ability, had a significant positive effect on recontract intention. Second, it was found that consultant ability, consultant knowledge, and consultant attitude, which are sub-factors of consultant ability, had a significant positive effect on consulting satisfaction and utilization. Third, consulting satisfaction and utilization were found to have a significant positive effect on recontract intention. Fourth, consulting satisfaction was shown to mediate the relationship between consultant ability and recontract intention. Fifth, consulting utilization was shown to mediate the relationship between consultant ability and recontract intention. The conclusions and implications of this study are as follows. First, it was demonstrated that consultant ability, consulting satisfaction and utilization are important in the recontract intention for industrial safety consulting. Second, as a result of analyzing the effect of consultant ability on recontract intention, consulting satisfaction and utilization, it was analyzed that the influence of consultant ability, consultant knowledge, and consultant attitude was significant in the order. Third, consulting satisfaction and utilization were found to mediate the relationship between consultant ability and recontract intention. In conclusion, It was demonstrated that consultant ability, consulting satisfaction, and consulting utilization had a significant impact on the recontract intention, and it was found that consulting satisfaction and utilization mediate the relationship between consultant ability and recontract intention. and it was discovered that the three sub-factors of consultant ability had a significant impact on consulting satisfaction, utilization, and contract renewal intentions in the order of ability, knowledge, and attitude. it was found that the consultant ability, consulting satisfaction, and the utilization of industrial safety consulting companies are all important factors that influence recontract intention. In addition, industrial safety consulting companies have laid the foundation that in order to greatly affect consulting satisfaction, utilization, and recontract intention by improving consultant ability, consultants' capability, knowledge, and attitude must be improved in order.

In the construction industry, lack of reliability in the quality of recycled aggregates, harmful substance problems, and negative consumer perceptions limit the expansion of the use of recycled aggregates. In this respect, existing studies mainly focus on the use of recycled coarse aggregates in concrete in consideration of durability. On the other hand, in the case of recycled fine aggregates, not only are there insufficient cases applied to major structures, but the scope of application is very limited due to lack of awareness. Therefore, the main purpose of this study is to present the possibility of their application in bearing and non-bearing wall structures through physical characteristics experiments of concrete bricks for masonry according to various mixing ratios of recycled fine aggregates and cement amounts. To this end, the compressive strength and absorption rate of concrete bricks were measured focusing on the mixing ratio of the recycled fine aggregate and the crushed fine aggregate and the amount of cement. As a result, it is found that it is possible to use 100% of recycled fine aggregate for 200kg/m³ of cement or 25% of crushed fine aggregate mixed with 75% of recycled fine aggregate for the same amount of cement to achieve the compressive strength of 13MPa, witch is one of the quality requirements for concrete bricks for bearing walls. In addition, it is found that to meet the strength of 8MPa, one of the quality requirements for non-bearing walls, it is sufficient to use 100% of the recycled fine aggregate for 100kg/m³ of cement. Through the absorption rate tests, it is also confirmed that the absorption rate of the concrete brick is 13% or less by meeting the required performance criteria. This means that even if recycled fine aggregate is used in the manufacture of concrete bricks, the quality standards required by KS F 4004 (concrete bricks) can be sufficiently met.

This study aimed to suggest the usability and optimal amount of Orostachys japonicas in foods. Orostachys japonicus powder was added at 0% (Con), 3% (O3), 5% (O5), 7% (O7), and 9% (O9) to rice muffins and the quality and antioxidant characteristics of the muffins were determined. The moisture content and pH of the muffins decreased as the amount of Orostachys japonicus powder added increased. The weight increased as the amount of Orostachys japonicas powder added increased, but the volume, specific volume, and baking loss rate decreased. The L-and b-values of the muffins decreased as the a-value increased. The texture, hardness, gumminess, and chewiness of muffins increased while adhesiveness, springiness, and cohesiveness decreased. Polyphenol, flavonoid, DPPH, and ABTS⁺ radical scavenging activity, as well as reducing power, increased as the amount of Orostachys japonicus powder added increased. In the sensory test, the 5-7% addition group showed high scores in appearance, flavor, taste, texture, and overall preference. The degree of flavor and astringency of muffins, which are evaluation items for characteristic strength, increased as the amount of Orostachys japonicus powder added increased, and the level of moistness decreased. Therefore, the addition of 5-7% of Orostachys japonicus powder is thought to have a positive effect on the muffins. The purpose of this study was to suggest the usability and optimal addition amount of Orostachys japonicus powder and to provide basic data on foods with Orostachys japonicus added.

The purpose of this study was to analyze the curriculum competencies of relationship-forming ability and practical problem-solving ability reflected in the activity tasks corresponding to the content elements of 'Love and marriage', 'Preparation for parenthood', 'Pregnancy and childbirth', 'Child care', and 'Family culture and intergenerational relationship' in the 2015 revised high school technology & home economics textbooks. The data are 330 activity tasks from 12 kinds of high school technology & home economics textbooks. The sub-factors of the relationship-forming ability were selected as Respect for Diversity, Consideration and Care, Family Relationship and Community Spirit, Empathy Ability, Conflict Management, and Communication, and the sub-factors of practical problem-solving ability were selected as Practical Reasoning, Decision Making, Value Judgment, Critical Thinking, and Executive Power. Based on the analysis criteria, the results of the two analyses and the expert review are as follows. First, regarding both the core concepts 'Development' and 'Relationship', the share of relationship-forming ability was relatively higher than practical problem-solving ability, and conflict management and executive power were the least reflected. For the core concept 'Development', Family Relationship and Community Spirit and Critical Thinking were the most reflected sub-factors, and for the core concept 'Relationship', Consideration and Care and critical thinking were the most reflected sub-factors. Second, in the case of the relationship-forming ability, the examples of activity tasks across sub-factors of each subject competency were devised to understand diverse opinions and sentiments and to develop competencies to care for each other and maintain healthy family relationships. In the case of practical problem-solving ability, the tasks allowed students to objectively analyze the socio-cultural background underlying the real-life problem, explore alternatives, and apply in their own lives.

Recent droughts make hydroelectric power generation (HPG) decreasing. Due to climate change in the future, the frequency and intensity of drought are expected to increase, which will increase uncertainty of HPG in multi-purpose dams. Therefore, it is necessary to estimate the amount of HPG according to climate change scenarios and analyze the effect of drought on the amount of HPG. This study analyzed the future HPG of the Soyanggang Dam and Chungju Dam according to the SSP2-4.5 and SSP5-8.5 scenarios. Regression equations for HPG were developed based on the observed data of power generation discharge and HPG in the past provided by My Water, and future HPGs were estimated according to the SSP scenarios. The effect of drought on the amount of HPG was investigated based on the drought severity calculated using the standardized precipitation index (SPI). In this study, the future SPIs were calculated using precipitation data based on four GCM models (CanESM5, ACCESS-ESM1-5, INM-CM4-8, IPSL-CM6A) provided through the environmental big data platform. Overall results show that climate change had significant effects on the amount of HPG. In the case of Soyanggang Dam, the amount of HPG decreased in the SSP2-4.5 and SSP5-8.5 scenarios. Under the SSP2-4.5 scenario the CanESM model showed a 65% reduction in 2031, and under the SSP5-8.5 scenario the ACCESS-ESM1-5 model showed a 54% reduction in 2029. In the case of Chungju Dam, under the SSP2-4.5 and SSP5-8.5 scenarios the average monthly HPG compared to the reference period showed a decreasing trend except for INM-CM4 model.

This study aimed to investigate changes in metamodeling recognition among chemistry teachers through a teacher educational program related to redox models and water electrolysis experiments. To this end, a science model education program was developed for 9 chemistry teachers and conducted over 10 lessons for a total of 40 hours. In addition, a pre- and post-survey was administered to determine teachers' metamodeling recognition in non-contextual and contextual situations. As a result of the study, through the science model education program, teachers showed educational effects in both non-contextual and contextual situations. In the case of non-contextual situations, the stages of scientific metamodeling knowledge development of chemistry teachers came out differently depending on the type of question. For example, the nature or purpose of the model, the modeling process, or the evaluation and improvement of the model improved from low to high, but there was no significant change because the perception of model change and diversity was already high in advance. In the case of contextual situations, the stage of scientific metamodeling knowledge development improved from objectivity to subjectivity in both the redox model theory class and the water electrolysis model experiment class. Therefore, through the 5E circular learning model-based education program, chemistry teachers' perception of metamodeling was clearly improved. However, the modeling activities of teachers in the water electrolysis model experiment class were different from the change in metamodeling perception. The types that teachers selected as additional experiments for modeling were analyzed in two ways. The first type is when they are interested in finding an ideal condition in which the ratio of hydrogen and oxygen gas is close to 2:1 through additional experiments. The second type is when additional experiments are designed with interest in why the experimental results are coming out like that. It was analyzed that the second type was the experiment necessary for modeling. In addition, modeling activities were analyzed into two types. The first was a type in which water molecules were directly decomposed in two electrodes to generate hydrogen and oxygen gas. This type was the case of regression to the textbook model regardless of the experimental results, and 6 chemistry teachers out of 8 were analyzed as this type. The second type was the type in which water reacted at the (+) electrode to generate other substances, and hydrogen ions reacted at the (-) electrode to generate hydrogen gas. Teachers who performed these modeling activities corresponded to the second type in additional experiments, and 2 chemistry teachers out of 8 corresponded to this. Therefore, it is necessary to provide an experience of activities corresponding to the second type of experiment and modeling through an educational program that provides an experience of directly modeling through experiments in order to develop modeling capabilities, unlike the development of metamodeling knowledge.

The purpose of this study is to develop a customized foot disease analysis and management system for diabetic patients to prevent foot ulcers in diabetic foot disease patients. This system utilizes image analysis technology to measure not only foot pressure, but also ankle deformation, body balance, and foot wounds. Through various data, it is possible to accurately analyze the state of foot deformation, and based on this, the exact state of deformation of the foot of a patient with diabetic foot disease was identified and a customized insole was produced. This study was conducted to examine the satisfaction level of using an application that checks the status of diabetic foot disease wounds and to identify the degenerative status of diabetic foot disease patients and foot disease patients by wearing customized insoles and to survey the satisfaction of wearing insoles. As a result of the study, the knee angle measured for plantar pressure was -0.8 ± 1.3 degrees and ranged from a minimum of -2.4 degrees to a maximum of 1.1 degrees, and there was no significant difference in valgus knee between both lower extremities (p = 0.534). There was a significant difference in tibial angle between both lower extremities (p < 0.001). Ankle angle on the left side was 2.6 ± 2.0 degrees, ranging from a minimum of 0 degrees to a maximum of 6.3 degrees, and on the right, it was 4.5 ± 2.1 degrees, with a distribution of minimum 1.5 degrees to a maximum of 9.1 degrees. There was a significant difference in ankle angle between both lower extremities (p = 0.011). They responded that they felt an average of 4.3 points of satisfaction with the plantar pressure measurement application. Respondents responded that they felt an average of 3.9 points of satisfaction with the use of customized insoles.

The purpose of this article is to examine the prospects of the religious cultural experience program of Daesoon Jinrihoe by referring to the current status of Korea's Buddhist temple stays, which began with the 2002 World Cup and have become a regular program for the general public with the establishment of the Cultural Corps of Korean Buddhism in 2004. The motivation for Korean participation is mainly rest, while foreigners tend to be more interested in Korean traditional culture. During the experience, the perceived value felt by the participants led to satisfaction and an intention to revisit. Temple stays have contributed to the globalization of Korean Buddhism. The temple stay of Daesoon Jinrihoe is a religious cultural experience program for the public. If it became a regular program, the target could be expanded to include foreigners who wish to experience Korean culture. The activities such as wearing Hanbok, taking a Dojang Tour, praying, and dialogue over tea can be allocated to the program. As a result, the perceived value by participants could be taken as a cognitive value. For instance, they could learn about Sangje's Reordering of the Universe that transformed the order of Sanggeuk (Mutual Contention) into the order of Sangsaeng (Mutual Beneficence). They way that they live their lives could change as a result of these new understandings. The emotional value of the experience would come from experiencing traditional Korean religious culture. The prospect of implementing such a program is twofold: firstly, there are the tasks of proper preparation, and secondly, there are the positive effects. The tasks would first involve creating a systematic and organized center point. Next there would be the matter of preparing spaces for the temple stay, and lastly, an online platform for advertisement, recruitment, and application would also be greatly beneficial. This is a vision that could contribute to the improving public image of the order, its globalization, and to the overall improvement of the facilities and management that would produce a more socially friendly environment.

The purpose of this study was to develop an educational smart app for classes by reconstructing some of the teaching-learning contents of the clothing preparation planning within the 'clothing preparation planning and selection' curriculum unit. To this end, a teaching-learning process plan was planned for the classes, a smart app was developed for classes, and feedback from home economics teachers and app development experts was received for the developed app. The main composition of the developed app consists of five steps. The first step is to set up a profile using a real photo, ZEPETO or Galaxy emoji, or iPhone Memoji. In the second step, students make a list of clothes by figuring out the types, quantities and conditions of their exisitng wardrobe items. Each piece of clothing is assigned an individual registration number, and stduents can take pictures of the front and back, along with describing key attributes such as type, color, season-appropriateness, purchase date, and current status. Step three guides students in deciding which garments to retain and which to discard. Building on the clothing inventory from the previous step, students classify items to keep and items to dispose of. In Step 4, Deciding How to Arrange Clothing, students decide how to arrange clothing by filling out an alternative scorecard. Through this process, students can learn in advance the subsection of resource management and self-reliance, laying the foundationa for future learning in 'Practice of Rational Consumption Life'. Lastly, in the fifth stage of determining the disposal method, this stage is to develop practical problem-oriented classes on how to dispose of the clothes to be discarded in the thirrd stage by exploring various disposal methods, engaging in group discussions, and sharing opinions. This study is meaningful as a case study as an attempt to develop a smart app for education by an instructor to align teaching plans and educational content with achievement standards for the class. In the future, upgrades will have to be made through user application.
