Under the recognition that the technological system of traditional flower design in Korea has been passed down from the past to the present, we extracted the type of design form from the flower decoration of the Joseon Dynasty, analyzed the expression technique, and examined the relationship with the modern traditional flower decoration in this study. As a result, most of the flower design works of the Joseon Dynasty mainly expressed one focal point at the central starting point. One central branch line was mainly used, and cut leaves were mainly used as the base material. Similar to the Joseon Dynasty, one central starting point and a base made of leaves are mainly used In modern flower design. In the frequency of use by expression technique, the stem exposure technique was used the most, and cut flowers and cut stems were used at a similar frequency in all techniques. As plant materials, cut flowers and cut stems were mainly used. In addition, non-plant materials such as feathers, fans, and brushes were also used for decoration. In conclusion, it can be seen that traditional flower decorations in Korea were systematically established in the Joseon Dynasty in terms of expression techniques and high-level flower design works were made. In the future, it will be necessary to study the history of our flower designs in more diverse ways and to develop modern flower designs while preserving historical traditions.

Human urine is a process of excreting waste products in the blood, and it is easy to collect and contains various substances. Urinalysis is used to check for diseases, health conditions, and urinary tract infections. There are three methods of urinalysis: physical property test, chemical test, and microscopic test, and chemical test results can be easily confirmed using urine test strips. A variety of items can be tested on the urine test strip, through which various diseases can be identified. Recently, with the spread of smart phones, research on reading urine test strips using smart phones is being conducted. There is a method of detecting and reading the color change of a urine test strip using a smartphone. This method uses the RGB values and the color difference formula to discriminate. However, there is a problem in that accuracy is lowered due to various environmental factors. This paper applies a deep learning model to solve this problem. In particular, color discrimination of a urine test strip is improved in a smartphone using a lightweight CNN (Convolutional Neural Networks) model. CNN is a useful model for image recognition and pattern finding, and a lightweight version is also available. Through this, it is possible to operate a deep learning model on a smartphone and extract accurate urine test results. Urine test strips were taken in various environments to prepare deep learning model training images, and a urine test service application was designed using MobileNet V3.

An artificial intelligence (AI) method based on image deep learning is proposed to predict the entire displacement shape of a structure using the feature of partial displacements. The performance of the method was investigated through a structural test of a steel frame. An image-to-image regression (I2IR) training method was developed based on the U-Net layer for image recognition. In the I2IR method, the U-Net is modified to generate images of entire displacement shapes when images of partial displacement shapes of structures are input to the AI network. Furthermore, the training of displacements combined with the location feature was developed so that nodal displacement values with corresponding nodal coordinates could be used in AI training. The proposed training methods can consider correlations between nodal displacements in 3D space, and the accuracy of displacement predictions is improved compared with artificial neural network training methods. Displacements of the steel frame were predicted during the structural tests using the proposed methods and compared with 3D scanning data of displacement shapes. The results show that the proposed AI prediction properly follows the measured displacements using 3D scanning.

In this paper, we propose a method to build a sample dataset of the features of eight sensor-only facilities built as infrastructure for autonomous cooperative driving. The feature extracted from point cloud data acquired by LiDAR and build them into the sample dataset for recognizing the facilities. In order to build the dataset, eight sensor-only facilities with high-brightness reflector sheets and a sensor acquisition system were developed. To extract the features of facilities located within a certain measurement distance from the acquired point cloud data, a cylindrical projection method was applied to the extracted points after applying DBSCAN method for points and then a modified OTSU method for reflected intensity. Coordinates of 3D points, projected coordinates of 2D, and reflection intensity were set as the features of the facility, and the dataset was built along with labels. In order to check the effectiveness of the facility dataset built based on LiDAR data, a common CNN model was selected and tested after training, showing an accuracy of about 90% or more, confirming the possibility of facility recognition. Through continuous experiments, we will improve the feature extraction algorithm for building the proposed dataset and improve its performance, and develop a dedicated model for recognizing sensor-only facilities for autonomous cooperative driving.

Nanoplastics (NP) exhibit distinct material properties compared to microplastics (MP), necessitating their separate recognition. Review of research outcomes and policy documents on NP reveals that most policy frameworks predominantly define MPs as solid synthetic polymer materials measuring 5 mm or less, but do not distinguish them from NP. However, recent revisions in regulations by the EU classify NPs as particles that range in size from 1 to 1,000 nm, as confirmed by some academic studies. Research on NPs often relies on experimental investigations centered around water systems, with a focus on high-concentration experimental conditions using spherical polystyrene-based NPs in behavior and impact studies. Notably, the environmental behavior characteristics of NP show differences in influence depending on the NP type, emphasizing the need for field simulation research. These challenges are mirrored in Korean society, so it is necessary to redefine NP to be distinct from MP in both research and policy. This study aimed to assess the current state of NP management globally and domestically and highlight policy considerations and issues in the existing response to NP. Upon comprehensive review, it becomes apparent that reaching an international agreement on MP faces methodological limitations, which could potentially burden efforts to precisely define NP size. Therefore, referencing the EU's recent regulatory revisions is crucial in domestic policy. Specific adjustments should commence from the MP concept through insights from the domestic industry, guidance from the academic community, and thorough discussions to ensure social acceptance.

Purpose: This study examined the status of food allergy management and importance-performance analysis (IPA) between elementary, and middle and high school employees in school foodservice. Methods: The participants were employees in elementary (n = 171) and middle and high schools (n = 187) in the Jeonbuk area. The demographic characteristics, the status of food allergy management, food allergy education, and the importance and performance status were assessed using a self-administered questionnaire. Results: Approximately 55.0% of employees in elementary and 32.6% in middle and high schools recognized that the foods in menu tables induced allergies. Approximately 93.0% of employees in elementary and 85.0% in middle and high school thought that food allergy management was an important part of school foodservice because of the possibility of health emergencies. Elimination and replacement meals were provided more in middle and high schools than in elementary schools. Food allergy education from nutrition teachers had been given to 62.6% of employees in elementary and 50.3% in middle and high schools. To prevent food allergy accidents, 72.4% of employees in elementary schools and 65.2% in middle and high schools wanted more accurate information on students with food allergies. As a result of IPA, elementary, middle, and high school employees were aware of the importance and performed well: 'Strict control of allergy-inducing foods because of cross-contamination'. On the other hand, they were not aware of the importance and performed them insufficiently: 'Know how to use epinephrine to prepare for emergencies'. Conclusion: Therefore, it is necessary to improve the consciousness of nutrition teachers for the effective application of food allergy education, especially the recognition of allergy-inducing foods and emergency responsive ability.

The purposes of this study were 1) to investigate eating behaviors and patterns in breast cancer patients using a newly developed food frequency questionnaire and 2) to examine perception and use of nutritional information about breast cancer treatment among cancer patients treated with radiation therapy. Sixty breast cancer patients (case group) undergoing radiation therapy in Ajou University Hospital, Suwon, South Korea and 79 healthy women (control group) participated in this study. Mean age of subjects in the control group was $46.00{\pm}7.88$ years and BMI was $23.12{\pm}2.85kg/m^2$, and that of the case group was $50.06{\pm}11.64$ years and $22.32{\pm}3.24kg/m^2$. The results of eating behaviors showed several significant differences between control and case groups. Breast cancer patients ate meals on a more regular basis, on time, and more frequently compared to control subjects. In addition, they preferred more salty or spicy and bland food compared to healthy women. According to answers from the food frequency questionnaire, breast cancer patients consumed significantly lower amounts of boiled white rice, meats and processed food, fish and shellfish, coffee, milk, and cheese, whereas they consumed a significantly large amount of boiled multigrain rice, vegetable, seaweeds, soybean and processed food, and yoghurt compared to healthy women. This study also observed the way in which cancer patients and healthy control subjects obtain information about breast cancer treatment and its reliabilities. Results showed that healthy women did not hesitate to obtain information from mass media, while breast cancer patients would obtain nutritional information from specialists rather than mass media. Results of this survey confirmed that breast cancer patients avoided intake of red meat protein, even though they already recognized the importance of dietary protein intake for recuperation and treatment of the disease. These results could be used for future diet and nutrition guidelines for breast cancer patients.

The purpose of this study was to analyze the effect of mediating variables on the relationship between job stress and stress response. A survey was conducted to 243 clinical dental hygienists from January 15, 2013 to March 20, 2013 and the data were analyzed using t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical multiple regression analysis. The subjects who worked in poor working environment, had high level of role conflict and overload and aggressive nature showed high stress responsivity (p<0.01). The variable that showed mediation effect on the relationship between job stress and physical discomfort, depression was shown to be personality type (p<0.05). Also, the variable that showed mediation effect on the relationship between job stress and turnover intention was social support (p<0.05). According to the results, personality type and social support were shown to be important parameters when it came to the relationship between job stress and stress response. Therefore, in order to reduce negative outcomes caused by stress, it is suggested to provide an educational opportunity on self-control management while increasing social support from the organizational and structural level. Especially, it is asked to expand the system that provides encouragement and recognition to feel the sense of achievement in the course of their duty execution.
