The purpose of this study was to investigate individuals' perceptions toward green tea and green tea cafes according to their usage of green tea cafes, gender, and marital status. The survey was conducted online and completed by 200 respondents who had been to green tea cafes and by 200 respondents who had not. The visitors of green tea cafes had more positive perceptions regarding the atmosphere, familiar taste, good quality of raw foods, freshness of foods, good service, excellent taste, and menu variety of green tea cafes. Males perceived green tea as 'good for health' more than the females. There was no difference in the perception of green tea cafes by marital status. Regarding a popularization plan for green tea cafes, the customers felt more need for a tea sommelier than the non-customers, and females versus males felt stronger about having a tea sommelier that would provide opportunities to taste various tea products and develop a green tea menu that considered nutrition and health. Unmarried respondents felt a greater necessity for having a place with a comfortable environment, tasting a variety of tea products, and having a chance to experience tea culture. When selecting a green tea cafe, the quality of the food and cleanliness of the cafe were considered to be most important. The implications of the data are discussed.

This study is an example of a Cinema Therapy class through the movie Life of Pi (2013). Cinema Therapy proceeds through the process of identification, empathy, projection, and observational learning through the cinema. Through research, students objectively examine the situation of the characters in the movie, identify themselves, and empathize with them. Students evaluate the situation of the character in the movie, and indirectly experience the hardships facing the character in the movie through the answer to "What would you do if I were the main character?" and think about what they would do. I admire the outstanding points of the main character and reflect on my life. Through this process, students examine the situation of their emotions and problems and specifically suggest ways to solve them. In the end, students' emotions can be fully healed through the movie. Healing through the cinema should start with the selection of the cinema in consideration of the healer's client. It is also necessary to sufficiently present a specific method of applying this. It is expected that the cinema healing plan will be able to develop further by presenting various healing methods in the future.

With the advent of the Fourth Industrial Revolution, there is an increasing demand for interdisciplinary studies in the realm of university education. Accordingly, this study sought to explore learners' perceived expectation factors for a modular curriculum, one of the primary strategies for curriculum revision in interdisciplinary departments, by applying the Expectation Theory. Learners' perceptions were measured pre and post during the second semester of 2022. The results confirmed that among the expectation factors, the selection factor significantly decreased after the course compared to before. Changes in the understanding and perceived difficulty level of tool utilization within the course may have influenced these results. The significance of this study lies in providing direction for curriculum revisions in interdisciplinary departments by analyzing learners' perceptions of the modular curriculum. Specifically, curriculum design should focus on reducing difficulties and cognitive burdens associated with educational tool utilization. Furthermore, considering that students' prior experience and understanding of educational tools can impact educational outcomes, it is crucial to factor these elements when designing a modular curriculum.

This paper proposes to apply machine learning to the process of predicting the slab thickness based on the structural analysis results or experience and subjectivity of engineers in the design of bridge data construction to enable digital-based decision-making. This study aims to build a reliable design environment by utilizing machine learning techniques to provide guide values to engineers in addition to structural analysis for slab thickness selection. Based on girder bridges, which account for the largest proportion of bridge data, a prediction model process for predicting slab thickness among superstructures was defined. Various machine learning models (Linear Regress, Decision Tree, Random Forest, and Muliti-layer Perceptron) were competed for each process to produce the prediction value for each process, and the optimal model was derived. Through this study, the applicability of machine learning techniques was confirmed in areas where slab thickness was predicted only through existing structural analysis, and an accuracy of 95.4% was also obtained. models can be utilized in a more reliable construction environment if the accuracy of the prediction model is improved by expanding the process

Objective: This study evaluated the health behavior level of urological cancer survivors after surgery. Understand the experience of change and identify the factors that affect it for health. Selection of the best intervention steps and effective intervention adopt a lifestyle. It is intended to contribute to the creation of basic data for development of guidelines. Methods: The study was conducted with patients diagnosed with urological cancer at a hospital in Seoul. Study data were obtained by having 100 patients who agreed to the study self-fill out a questionnaire through interviews, and the 2018 World Cancer Research Fund and American Institute for Cancer Research Score (2018 WCRF/AICR SCORE) was used to estimate the level of health behavior. Results: The study examines health behavior among urolgical cancer survivors based on the 2018 WCRF/AICR SCORE. Higher household income and younger age were associated with better health behavior scores, with those under 60 and earning over 3 million won being more likely to have higher scores. Conclusion: Based on these results, this study requires comprehensive data collection considering the missing variables, suggesting that high household income and young age can positively affect healthy behavior. In addition, we conclude that education for cancer survivors and development of strategies to bridge the health gap for low-income and elderly populations are necessary.

This study examines whether startup firms start with the resources they already have and expand the resources they can mobilize in the process of business management (Effectuation Model) using public data provided by the government. The results of the study show that the Effectuation Model can partially explain the behavior of early-stage startup firms. Therefore, in terms of policy implications based on these findings, government policies for entrepreneurship should not be based on the selection of companies based on sophisticated business models and hypothetical profit models, but rather on a system that actively supports entrepreneurship in areas that are challenging, even if they seem somewhat reckless at the moment, or that best match the entrepreneur's knowledge. Next, in order to actively spread entrepreneurship, it is necessary to spread business history or entrepreneurial experience. To this end, it is necessary to drastically change the current financial system for startups, where the founder bears all the financial risk, and to more actively consider ways to reduce the risk of startups by allowing society and the financial system to share some of the risk of startups.

Backgrounds/Aims: Ambulatory laparoscopic cholecystectomy (LC) is increasingly recognized for its advantages over the inpatient approach, which advantages include cost-effectiveness and faster recovery. However, its acceptance is limited by patient concerns regarding safety, and the potential for postoperative complications. The study aims to compare the operative and postoperative outcomes of ambulatory LC versus inpatient LC, specifically addressing patient hesitations related to early discharge. Methods: In a retrospective analysis, patients who underwent LC were divided into ambulatory or inpatient groups based on American Society of Anesthesiologists (ASA) classification, age, and the availability of postoperative care. Propensity score matching was utilized to ensure comparability between the groups. Data collection focused on demographic information, perioperative data, and postoperative follow-up results to identify the safety of both approaches. Results: The study included a cohort of 220 patients undergoing LC, of which 48 in each group matched post-propensity score matching. The matched analysis indicated that ambulatory LC patients seem to experience shorter operative times and reduced blood loss, but these differences were not statistically significant (35 minutes vs. 46 minutes, p-value = 0.18; and 8.5 mL vs. 23 mL, p-value = 0.14, respectively). There were no significant differences in complication rates or readmission frequencies, compared to the inpatient cohort. Conclusions: Ambulatory LC does not compromise safety or efficacy, compared to traditional inpatient procedures. The findings suggest that ambulatory LC could be more widely adopted, with appropriate patient education and selection criteria, to alleviate concerns and increase patient acceptance.

To reduce the losses caused by aging failure of insulation gate bipolar transistor (IGBT), which is the core components of nuclear power plant rod position indicating and rod control (RPC) system. It is necessary to conduct studies on its life prediction. The selection of IGBT failure characteristic parameters in existing research relies heavily on failure principles and expert experience. Moreover, the analysis and learning of time-domain degradation data have not been fully conducted, resulting in low prediction efficiency as the monotonicity, time correlation, and poor anti-interference ability of extracted degradation features. This paper utilizes the advantages of the stacked denoising autoencoder(SDAE) network in adaptive feature extraction and denoising capabilities to perform adaptive feature extraction on IGBT time-domain degradation data; establishes a long-short-term memory (LSTM) prediction model, and optimizes the learning rate, number of nodes in the hidden layer, and number of hidden layers using the Gray Wolf Optimization (GWO) algorithm; conducts verification experiments on the IGBT accelerated aging dataset provided by NASA PCoE Research Center, and selects performance evaluation indicators to compare and analyze the prediction results of the SDAE-LSTM model, PSOLSTM model, and BP model. The results show that the SDAE-LSTM model can achieve more accurate and stable IGBT life prediction.

The objective was to know if corn growers at Hongchcel County, Kangwon-do, where corn is the major agricultural product, control weeds effectively and use herbicides properly to control weeds. Sixty-eight corn growers at Hongchon were participated in this survey. Corn growers have noxious weeds, such as hairy carbgrass, common purslane, lambsquarters, Asiatic dayflower, mugwort and barnyard grass in their corn fields. Forty-four percents of the answered corn growers control weeds by hand weeding, and the others by a combination of physical and chemical methods. Corn growers have a preference of paraquat and alachlor for a pre-emergence treatment (94% of the answered) and of paraquat, glufosinate, glyphosate and fluazifop-P-butyl for a post-emergence treatment (87% of the answered). Corn growers did not select and use herbicides in a proper manner. fifty-four percent of the answered corn fevers selected herbicides by their own experience and 18 percent by neighbors recommendation. Herbicides were not selected and used in a proper manner by corn growers: 54 percent of the answered selected herbicides by the experience of growers and 18 percent by the recommendation of neighbors. In addition, a half of the answered applied over two-fold higher amounts of herbicides than the recommended rate. With these improper- selection and use of herbicides, 37 percent of the answered have experienced the crop damage and 42 percent the herbicide poisoning. We conclude that the development of the educational program for the proper selection and use of herbicides is needed for corn growers in Kangwon-do.
