The number of galleries across the country is increasing as interest in cultural life increases due to the increase in national income. However, museum satisfaction is relatively low compared to other services. In this paper, we propose a service that provides preference information based on machine learning in embedded system environment in order to increase museum satisfaction. The proposed algorithm implements an embedded system using Raspberry Pi. Machine learning was used to find works similar to the viewer's favorite works, and several models were compared to select models applicable to embedded systems. By using the preference information, it is possible to effectively organize the gallery exhibition contents to increase the exhibition satisfaction and the re-visit rate of the museum.

This study was conducted to analyze the characteristics of visitors to Hadong Bukcheon Iceland Poppy (BIP) Festival in order to sustain and enhance local flower festivals as a garden tourism. A questionnaire was distributed to BIP Festival visitors from May 18 to 27, 2018. A total of 167 responses were subject to be analyzed. Descriptive statistics analysis was mainly used and focused on describing the results in direct to explain the BIP Festival as a garden tourism. The number of female visitors and those in their 40s and 50s was high. Most of the visitors were found to live in other cities or counties near the area where BIP Festival was held and to prefer festivals held on the theme of nature and local features. The revisit rate and awareness of BIP Festival were 52.1% and 72.5% respectively. They mainly obtained the information on BIP Festival from people around them including family members, friends and colleagues, or from the Internet. Most answered that BIP festival was the most important destination on their trip. The major motives of BIP Festival visit included "spending quality time with family or friends (34.1%)", "appreciating Iceland poppy and gardens (25.6%)", and "enjoying oneself (tranquility, mental rest, etc.; 21.3%). As a companion, family and friends/colleagues accounted for 62.3% and 26.3% respectively. Most were found to spend 1-2 hours on visiting BIP festival and stay in Hadong county for a quarter of a day. In satisfaction of BIP Festival itself, "display and maintenance of Iceland poppy (3.76)" and "easiness of viewing (places arrangement, path, etc.) (3.57)" were high.

Background and Objectives The picosecond 755 nm alexandrite laser was first approved by the US FDA in 2012. A previous study described the use of a 1,064 nm picosecond laser with a micro-lens array (MLA) in peri-areolar scarring from breast reconstruction surgery and reported significant improvement in the texture and aesthetic appearance of the scar without other wound complications. The purpose of this study was to evaluate the improvement of overall scarring, not just pigmentation, in the picosecond laser treatment of patients with pigmentations. Materials and Methods Sixteen patients who underwent 1,064 nm picosecond laser treatment from June 2016 to December 2018 were enrolled in this study. Patients received two to six sessions of picosecond laser treatment at intervals of 4 weeks. Before and after the laser treatment, the patients evaluated their own satisfaction score and a physician evaluated the Vancouver Scar Scale. To evaluate the satisfaction score and complication rate, a retrospective chart review was done. Results Seven were female and nine were male. The mean of the patients' satisfaction score before the treatment was 1.44 (interquartile range [IQR], 1-2) and 3.00 (IQR 2.25-3.75) six months after treatment. The mean of the Vancouver Scar Scale before the treatment was 9.69 (IQR 8-11), and 6.25 (IQR 5-7.75) six months after treatment. All the results were statistically significant (p<0.01). Conclusion This study provides evidence that the use of a 1,064 nm picosecond laser treatment for pigmented scars can be effective in improving the pigmentation and overall scar status, including vascularity, height, and pliability, with the results of a decrease in the VSS scores between treatments.

Objective: We aimed to evaluate the clinical and imaging factors associated with hemorrhagic complications and patient discomfort following ultrasound (US)-guided breast biopsy. Materials and Methods: We prospectively enrolled 94 patients who were referred to our hospital between June 2022 and December 2022 for US-guided breast biopsy. After obtaining informed consent, two breast radiologists independently performed US-guided breast biopsy and evaluated the imaging findings. A hemorrhagic complication was defined as the presence of bleeding or hematoma on US. The patients rated symptoms of pain, febrile sensation, swelling at the biopsy site, and dyspnea immediately, 20 minutes, and 2 weeks after the procedure on a visual analog scale, with 0 for none and 10 for the most severe symptoms. Additional details recorded included those of nausea, vomiting, bleeding, bruising, and overall satisfaction score. We compared the clinical symptoms, imaging characteristics, and procedural features between patients with and those without hemorrhagic complications. Results: Of 94 patients, 7 (7%) developed hemorrhagic complications, while 87 (93%) did not. The complication resolved with 20 minutes of manual compression, and no further intervention was required. Vascularity on Doppler examination (P = 0.008), needle type (P = 0.043), and lesion location (P < 0.001) were significantly different between the groups. Patients with hemorrhagic complications reported more frequent nausea or vomiting than those without hemorrhagic complications (29% [2/7] vs. 2% [2/87], respectively; P = 0.027). The overall satisfaction scores did not differ between the two groups (P = 0.396). After 2 weeks, all symptoms subsided, except bruising (50% 2/4 in the complication group and 25% [16/65] in the no-complication group). Conclusion: US-guided breast biopsy is a safe procedure with a low complication rate. Radiologists should be aware of hemorrhagic complications, patient discomfort, and overall satisfaction related to this procedure.

This study sheds light on the viewing experiences with ≪Game Society(2023)≫ through literature review and quantitative methodology to analyze the perceived value, the perceived experience quality, the attitude toward the exhibition, and the intentions to use of the exhibition. Survey participants demonstrate a tendency to rate the entertainment value higher than the esthetic and educational values. The aforementioned hedonic value shows a significant positive correlation with the degree of satisfaction, while educational and esthetic values exhibit negative corr)elations. Regarding the perceived experience quality, the attractiveness of the exhibition themes significantly influences the degree of satisfaction. Hypothesis testing results indicate that the five detailed factors related to the intention to use of the exhibition are significantly positively correlated with both the degree of satisfaction and the degree of immersion.

Organizational culture represents values and beliefs that members share and is a factor that influences the behavior of organizational members. Understanding organizational culture is a source of competitive advantage to increase the rate of success and efficient management of the organization. The purpose of this study is to determine the relationship between job satisfaction and the turnover intention of sailors. To achieve its purpose, the study was developed by examining the properties to be used for the demonstration and the purpose of the study, and verifying the hypothesis through empirical analysis. Empirical analysis showed that developmental, rational, and group cultures among organizational culture have a significant impact on job satisfaction. When the organizational culture has a group culture and an extrinsic factor to job satisfaction, it has a negative effect on turnover intention. This implies that the shipping company needs to foster organizational culture to feel like growing for Sailors themselves and to improve relationship and cooperation with other sailors rather than trying to control strongly. The shipping company will need to educate members and manage its organizational culture consistently for improving the organizational culture.

The electronic toll collection system(ETCS), is globally used in about 40 countries. In Korea, the Korea Expressway Corporation led the nationwide introduction of the ETC system in 2007 under the brand name of the Hi-pass. Since then, Hi-pass, with its rate of average daily use reaching about 70%, has become an essential facility in Korean expressways. To identify users' perception on Hi-pass (satisfaction, preference, etc.), this study conducted a Modified Importance-Performance Analysis (M-IPA). With this, this study attempted to identify the kind of efforts necessary to enhance current Hi-pass users' convenience and satisfaction. According to the result of M-IPA, the items including "non-stop payment" and "toll discount" are identified as key items that require further improvement. For improvement in the "non-stop payment" item, operations of Hi-pass toll booths appropriate for the demand for Hi-pass use and the selection of Hi-pass booths' locations in consideration of entry and exit lanes need to be improved. In addition, with regard to the "toll discount" item, although toll discount is currently provided to Hi-pass users, thus, PR thereof will have to be strengthened. It is expected that this study will be used as basic data to devise methods of enhancing Hi-pass usage through improvement of Hi-pass users' satisfaction.
