We analyze the accuracy of emotion analysis of natural language processing deep learning model and propose to use it for emotional content development. After looking at the outline of the GPT-3 model, about 6,000 pieces of dialogue data provided by Aihub were input to 9 emotion categories: 'joy', 'sadness', 'fear', 'anger', 'disgust', and 'surprise'. ', 'interest', 'boredom', and 'pain'. Performance evaluation was conducted using the evaluation indices of accuracy, precision, recall, and F1-score, which are evaluation methods for natural language processing models. As a result of the emotion analysis, the accuracy was over 91%, and in the case of precision, 'fear' and 'pain' showed low values. In the case of reproducibility, a low value was shown in negative emotions, and in the case of 'disgust' in particular, an error appeared due to the lack of data. In the case of previous studies, emotion analysis was mainly used only for polarity analysis divided into positive, negative, and neutral, and there was a limitation in that it was used only in the feedback stage due to its nature. We expand emotion analysis into 9 categories and suggest its use in the development of emotional content considering it from the planning stage. It is expected that more accurate results can be obtained if emotion analysis is performed by additionally collecting more diverse daily conversations through follow-up research.

The development of an analysis model that reflects the microstructure characteristics of polyvinyl alcohol (PVA) fiber-reinforced cementitious composites, which have a highly complex microstructure, enables synergy between efficient material design and real experiments. PVA fiber orientations are an important factor that influences the mechanical behavior of PVA fiber-reinforced cementitious composites. Owing to the difficulty in distinguishing the gray level value obtained from micro-CT images of PVA fibers from adjacent phases, fiber segmentation is time-consuming work. In this study, a micro-CT test with a voxel size of 0.65 ㎛³ was performed to investigate the three-dimensional distribution of fibers. To segment the fibers and generate training data, histogram, morphology, and gradient-based phase-segmentation methods were used. A U-net model was proposed to segment fibers from micro-CT images of PVA fiber-reinforced cementitious composites. Data augmentation was applied to increase the accuracy of the training, using a total of 1024 images as training data. The performance of the model was evaluated using accuracy, precision, recall, and F1 score. The trained model achieved a high fiber segmentation performance and efficiency, and the approach can be applied to other specimens as well.

This study examines the living conditions and life satisfaction of single-person households according to their life cycle. The survey was conducted from August to October 2022, and respondents were single-person households from Kimpo, South Korea. The respondents were categorized to three groups namely, young, middle-aged, and older adults by life cycle, and items regarding their sociodemographic background, personal life, family relations, and life satisfaction were included in the analysis. Descriptive statistics, Chi-square analysis, analysis of variance, and multiple regression analysis were performed. The key findings were as follows. First, significant differences were found according to life cycle in the respondents' diet, clothing, housing, financial and home management, self-care, and leisure life. Second, the variables that significantly affected the level of life satisfaction of single-person households were the life cycle with young adults showing a higher level of satisfaction; having a family member to care; living alone voluntarily, discrimination experience; community awareness; and ties with the local community. Based on the results, it is clear that single-person households have different needs and problems in each stage of life cycle. Thus, to reflect the different experiences and needs of single-person households by life cycle, tailored policy and programs should be provided for young, middle-aged, and older adult single-person households.

This study analyzed the composition of the time use and childcare time use of working mothers and fathers of Generations X and Y, differences between generations, differences between mothers and fathers, and factors affecting childcare time. We analyzed the lifetimes of working parents of preschool children(n=2,287) using Statistics Korea's Time Use Survey for 2014 and 2019. The main results are as follows: First, when comparing the lifetimes of Generations X and Y, in 2014, Generation Y mothers had longer commuted times, whereas for fathers, there was no difference between generations. Second, comparing the time use of Generations X and Y, regardless of the survey period, Generation Y mothers had longer sleep times than their counterparts, while Generation Y fathers had longer time in sleep, home management, and childcare than their counterparts. Third, in analyzing the factors affecting parents' childcare time for mothers of both generations, the less sleep times, mealtimes, working times, commuted times, home management times, and leisure times, the longer the childcare times. In the case of fathers, for Generations X and Y, the less sleep times, mealtimes, market work times, commuted times, and leisure times, the more childcare times. However, in Generation X fathers, home management time and the gender role attitude affect childcare time. While the generation gap was not clear for mothers, it was confirmed for fathers. Therefore, it was proposed not only gender differences but also generational characteristics should be taken into account to provide implications for child care policies, especially for fathers, in community care support systems incluing education and counseling programs.

Background : Until the early 1990's in Korea, treatment outcomes of patients with pulmonary tuberculosis in the private sector were reported to be inferior to those of the public health center under the National Tuberculosis Programme. The purpose of this study was to analyze the clinical characteristics and the treatment efficacy of the patients with pulmonary tuberculosis recently diagnosed at a private general hospital. Materials and Methods : The study included all pulmonary tuberculosis patients diagnosed at Samsung Medical Center and notified to the public health center from August 2000 to January 2001. Results : Of the 232 patients included in the study during a 6-month period, 188 were (81.0%) initial treatment cases and 44 (19.0%) were re-treatment cases. Eighty-three (35.8%) patients had smear-positive sputa, and 27 (11.6%) had smear-negative, culture-positive sputa. Initial sputum examinations were not performed in 47 (20.3%) patients. A six-month, short-course treatment using isoniazid, rifampin, ethambutol and pyrazinamide was prescribed for 31.4% of the patients under the initial treatment. The success rate (cured plus treatment completed) of the initial treatment for the smear-positive patients was 69.1%. Eleven (13.3%) of the 83 patients with smear-positive pulmonary tuberculosis discontinued their treatment without notice. Conclusions : To improve the treatment efficacy and decrease the default rates of the patients with pulmonary tuberculosis in the private sector, further efforts are required in line with the Korean Academy of Tuberculosis and Respiratory Disease Treatment Guidelines and in the implementation of an appropriate model of public-private mix for tuberculosis control in Korea.

This study investigated the quality characteristics of kiwi wine during low temperature aging on several alcohol fermentation strains. Alcohol content increased sharply from 2 days of fermentation, and then maintained steadily after 8 days of fermentation. In the alcohol content of kiwi wine on several alcohol fermentation strains such as Sacch. cerevisiae GRJ, Sacch. kluyveri DJ97 and Sacch. cerevisiae Wine 3 showed a high value of more than 13%, 12.7% for Zigosacch. cerevisiae JK99 and 12.3% for Sacch. cerevisiae OMK, respectively. Sugar content decreased steadily during fermentation and then showed approximately $10^{\circ}$Brix on 8 days of fermentation. Total acidity ranged $1.03{\sim}1.04%$ in total samples, increased slowly during fermentation and then maintained steadily during aging. During the fermentation, L value in Hunter's color value continued to increase, a value decreased steadily and b value showed high yellow to approximately 20.0. For aging duration, L and b values decreased while a value increased. Glucose and maltose were detected as free sugars of kiwi wine. In volatile flavor compounds, alcohols were identified differently on alcohol fermentation strains, but the others showed similar tendency. In conclusion, quality characteristics of kiwi wine on several alcohol fermentation strains showed similarly; however, Sacch. cerevisiae Wine 3 was overall the most suitable.

This study was conducted to provide exportation strategy by surveying on preference of Japanese consumers on cut chrysanthemum exported. The survey was conducted two times by a local survey company in Japan, and the surveys were conducted largely on chrysanthemums for casual flowers and the altar. After departmentalizing Japanese consumers per groups the result were analyzed through conjoint and cluster methods, flower colors and shape were used relatively higher rate for selection criteria of flowers in every group in the case of casual flowers. Group 1 comprised of 60 year-old housewives who reside in a small city with high school diploma and annual income less than 300 million yen, and group 2 of 40 year-old housewives who are small city residents with high school diplomas and annual income of 300 million yen show higher rate of use in flower shape than colors. Another group 3 whose members are 50 year-old housewives, small city residents with high school diplomas and annual income of 600 million yen showed higher rate of use colors than the shape for selection criteria of flowers. The consumption characteristics according to the ages of the consumers showed a pronounced tendency. The 40-50 year-old housewives preferred single flowers packed with other flowers, and the 60 year-old housewives double flowers packed with only chrysanthemums. In flower color, the 50-60 year-old housewives preferred white and yellow flowers, and the 40 year-old housewives pink and yellow flowers. Therefore, there are needs for development strategy of new products considering the consumption characteristics of flower shape and color according to the ages of consumer. After analyzing the chrysanthemums for altar by departmentalization of Japanese consumers, every group showed relative higher rate of use for flower shape for selection criteria of flowers. According to the analysis on the consumption characteristics, group 1 which is comprised of 30-40 year-old housewives who reside in small city with high school diplomas and income less than 300 million yen, and the group 2 of 20 year-old housewives who reside in small city with college diplomas and annual income less than 300 million yen. They are very sensitive to the price of the products while the group 3 of 50 year-old housewives who reside in small city with high school diplomas and annual income less than 300 million yen are insensitive to the price. The 30-50 year-old housewives preferred white and pink flowers, and the 20 year-old housewives yellow and pink flowers. In flower shape, the 50 year-old housewives preferred anemone shape, the 30-40 year-old housewives double shape, and the 20 year-old housewives pompon shapes. Therefore, the white, double flowers for the 30-40 year-old housewives and the yellow, pompon flowers for the 20 year-old housewives are needed to be created at the lowest cost, while the white, anemone flowers are needed to created at higher cost with high quality. In light of these results, it is considered that we should understand the types of purchasing products through consumption characteristics of Japanese consumers. Also we should plan, create market-oriented and consumer-oriented products, and should export them in order to expand more exportation.
