This study investigates which sound quality indices except SPL raise annoyance response. For investigation, auditory perception experiments for road traffic noise with identical linear SPL were performed by Paired Comparison Method. The numerical results of a Paired Comparison experiment express relative preference about annoyance. So that these relative preference scores are to be correlated to sound quality indices, which are absolute, a transformation is required to go from the relative domain to an absolute and linear scale of preference. The results of the transformation will be the 'merit values,' which quantifies the annoyance(in this case) of the road traffic noise on a linear scale. Using multiple regression, a formula is established that can calculate predicted merit values. Furthermore, This investigation offers a method selecting sound samples that represent various sound quality indices values to use experiment.

With Recently in art and culture domains, there's rising controversy over shared economy and public domain works. The government is introducing institutional measures such as Gongumadang and KOGL(Korea Open Government License) program to expand the grounds for public domain works. In order to promote and facilitate the use of public domain works, it is imperative to understand how the providers who create and provide the public domain works, as well as the users, perceive shared economy and public domain works. However, preceding studies usually put emphasis on the meaning and significance of the shared economy and show limitation of not discussing providers' perception on shared economy and public domain works. Therefore, this study examines to see if there's a difference of perception between the consumers/users and the providers who owns the copyright of public domain work.

Background: Surgical and non-surgical periodontal procedures often lead to postoperative pain. Clinicians use pharmacological methods such as anesthetics, anti-inflammatory drugs, and analgesics for relief. However, the multitude of options makes it challenging to select the best approach for routine dental care. Objective: This review aimed to describe previous studies regarding the pharmacological management used for pain control during periodontal procedures as well as factors that may interfere with patients' perception of pain. Methods: We included studies (period of 2000-2023, whose approach corresponded to the pharmacological protocols used for preoperative, trans-operative, and postoperative pain control in adult patients undergoing surgical and non-surgical periodontal therapy. Results: A total of 32 studies were included in the analysis, of which 17 (53%) were related to anesthetic methods and 15 (47%) were related to therapeutic protocols (anti-inflammatory/analgesic agents). These studies predominantly involved nonsurgical periodontal procedures. Studies have reported that factors related to age, type of procedure, and anxiety can influence pain perception; however, only seven of these studies evaluated anxiety. Conclusions: Numerous methods for pain control can be applied in periodontal therapy, which are accomplished through anesthetic methods and/or therapeutic protocols. Factors such as anxiety, age, and type of procedure are related to pain perception in patients. Thus, it is the responsibility of dentists to evaluate each clinical situation and define the best protocol to follow based on the literature.

Online financial technology products are an important consumer finance innovation. While a large body of previous research has focused on initial adoption and consumer willingness to use these products, little research explores the continued use of these products beyond the initial adoption phase. In particular, special attention should be paid to how users' trust and perceptions of privacy and security affect continued use behavior. This paper integrates the expectation confirmation model of information system continuance (ECM-ISC), the information system success model (ISSM) and the security and trust literatures to investigate continued use of online financial technology. To test the research model, we collected 398 valid questionnaires from Ant Credit Pay users. The research results show that system and service quality positively impact users' expectation confirmation, while information quality has no significant impact. Expectation confirmation and perceived usefulness positively affect user satisfaction. Moreover, the user's perception of privacy and security plays a vital role in user satisfaction. Satisfaction and perceived trust jointly promote users' continuance behaviors. Findings of this study indicates the importance of the information system success factors and security factors due to their influence on the continued use of Fintech products. This conclusion has implications for enterprises in improving the product qualities and enhancing the degree of security to meet user needs.

Purpose: This study was conducted to use as a preliminary data to improve the quality of clinical nursing education by comparing the perception of teaching effectiveness in nurses and nursing students. Method: The participants were 165 nurses and 289 nursing students. Data was collected from June 2 to 16, 2008. The research instruments used an effective clinical instructors which was developed by Reeve(1994). Result: The perception of teaching effectiveness in nurses and nursing students were 3.45 and 3.19 respectively and it showed that nurses' perception of teaching effectiveness are higher than that of nursing students. Nurses had strong points in the factors of "interpersonal relationship/ communication", "availability as a supporter", "teaching method and evaluation".In additions, the teaching effectiveness had significant differences to age, years of work, position, educational background and job satisfaction in nurses, otherwise, sex, differences of educational level, satisfaction of clinical practicum and major in students. Conclusion: It is needed a further study as below: to develop an education system which is to improve an interpersonal relationship and to upgrade the quality of educator; to develop a teaching method program of clinical nursing education to improve teaching effectiveness.

This study designed the research model to identify whether the characteristics of cultural programs of public libraries and middle-aged people's experience of the programs impact on their life satisfaction. To verify our model, we conducted our survey to random middle-aged users of five public libraries in Gyeonggi-do and nine public libraries in Seoul, and 246 valid samples are used. Our analysis showed that the characteristics of cultural programs and middle aged people's experience of the programs affect their perception of cultural programs, and the regional perception of public libraries had a significant effect on fulfilling personal needs for life satisfaction. Our analysis also showed the change in values of public libraries that spread to the realm of daily life. This study is meaningful in suggesting directions for national and local public library policies and public library cultural programs.

The algorithm is applied on the premise that the image generated by AI can be recognized and used smoothly by the user. Other assets are not exposed to the user or discarded because they are unnecessary or unfamiliar. This study aims to expand the scope of the utility of the image generated by AI, which is used as a high-level tool in the design field. To this end, we first examined human information processing and reflection in AI by the cognitive paradigm by examining previous studies and cases, and discussed the value of expansion by focusing on creativity and bottom-up processing of AI's self-organization. Considering the human recogmition process that instinctively grasps an object, the following AI usability was proposed. It is to utilize AI as a high-level tool applied appropriately to human perception, or to utilize the derivative itself by bottom-up self-organization. In addition, it is to set the algorithm to the minimum intervention so that basic elements such as shape, color, size, texture, and movement are composed of figure-ground according to the human perception process that instinctively grasps an object, and to utilize the results. Limiting the use of AI to a tool suitable for human perception and information processing or production by designers or general users is to operate only a part of the convenience and usability of AI. The image creation through AI's self-organization, as seen from the cognitive paradigm, is a step toward opening a new era of design where technical aesthetics meets devices, just as design has been constantly developing in pursuit of novelty and differentiation due to its nature.

Shippers face uncertainty and risks until the delivery of goods to the buyer (importer). To avoid these uncertainty and risks, shippers use the abroad logistics center and then try to construct continuous contract relations. From this viewpoint, this study examines the motivations of shippers to take advantage of the logistics center and perception difference for service quality according to the characteristics of shippers. For this purpose, T-test and ANOVA analyses are conducted using SPSS 21.0. The results suggest the following implications. First, there are no differences in perception regarding the motivation to take advantage of the logistics center for the size and characteristics of products. Second, the main motivating factors are maneuver to competitors and meeting buyers' demands by using the abroad logistics center. Furthermore, there is the level of perception for service quality regarding packaging and labeling in the logistics center. In contrast, the problem process and the quality of the order progress information is higher. Finally, specific logistics services are required depending on individual products because each product's characteristics are different.
