Purpose. This study was to investigate the degree of refractive error that occurs depending on the measurement location of the subject when performing a refraction test using the automatic refractor. Methods. When performing the auto-refraction test, measurements were taken while increasing the distance between the forehead and the forehead rest, and the measurements were made by tilting the head clockwise and counterclockwise. Results. During the auto-refraction test, significant refractive error occurred when the forehead was not attached to the forehead support or the subject's head was turned clockwise or counterclockwise. Conclusions. When performing a refraction test using an automatic refractor, the examiner will have to pay attention to whether the subject's forehead is in close contact with the forehead rest, and whether the head is tilted.

This study attempted to analyse the collections of public libraries in terms of their subject distribution and currency. It was expected that the analysis would give public librarians some suggestions as to their collection development policy making. This study team selected 423 Korean public libraries across the country and scrutinized the collections by their classes of Korean Decimal Classification(KDC) and publishing years. The study results indicated that there was some subject disproportion in public library collections. Literature and social sciences were accounting for 54.8% of whole collections. Currency of collections of public libraries could be said relatively excellent. It was found that 64.9% of whole collections had been published after 2000.

Purpose: The concept of News-finds-me Perception (NFMP) is gaining increasing scholarly interest due to its wide-ranging findings and implications in digital communications and marketing. From the retail marketing and communication approaches, social media is an effective tool to effectively communicate and persuade customers and stakeholders. Nevertheless, a scarcity of systematic review studies that systematically assemble prior research in the field is recognized. Consequently, this research investigated the Scopus database for articles pertaining to NFMP. Research design, data and methodology: The search was conducted on August 24, 2023, retrieving 46 documents. Following a data-cleaning process, 31 documents remained, providing evidence of the subject area's five-year development. The data was refined with OpenRefine and analyzed with VosViewer. Results: An overview of the subject's expansion is presented, which comprises the most cited documents, authors, organizations, journals, and countries. Furthermore, the investigation examines the influential studies that furnished scientists with essential knowledge and identify the current research trend of the research subject. Conclusions: Based on the results, the study proposes theoretical and practical implications, encouraging academics to further integrate the concept with various communication and marketing theories, as well as the retail marketing context, to gain a better understanding of its complex impacts.

In this paper, we implemented a LED sensitivity illumination system, being driven in response to changes in the biological signals of GSR and PPG signal. After measuring biological signals of a human body from GSR and PPG sensor modules, MCU decided the state of relaxation or arousal of the subject, being based on the wake relaxation identifying map proposed in this paper. A developed LED sensitivity illumination system makes the subject to reach a normal state by giving a change of the LED illumination color, corresponding to a state of the subject.

This study investigates author cocitation and author transition analysis which are two techniques to be used to construct author and concept networks by using a test collection of 4, 598 documents on the subject of chemistry. The author and concept networks can be used to understand the structual Knowledge of terms as well as intellectual structure of science. So, these networks could be basic data of knowledge base for subject literature.

The purpose of this study was to investigate the differences in the perception of Home Economics between female and male among high school students who have learned Home Economics and who have never learned. The number of 400 samples were analyzed with frequencies, percentages, t-test, regressions and $\chi$(sup)2 analyses by SPSS/Win. The results showed that the male students who have taken Home Economics were more likely than those who have never taken perceived Home Economics as a living science and to be interested in the subject. There were sexual differences among high school students who have learned the subject in favorite units, increases in interests, satisfaction with the contents, etc. Sex and the level of participating household works were the most influential factors on the perception of the subject of high school students.

As result of analysis of the importance in this study majority the answerers indicated as recognize it important and indicated that shows difference in average among the groups. In the age there was difference among group by marketing quality and symbolic quality of menu was indicated and in the symbolic quality factor of menu as the younger age indicate much more important. There was no factor indicates do florence in average among groups subject to educational degree however, in the marketing quality and symbolic quality of the menu the higher academic degree regards it higher as indicated. As a result of difference analysis subject to channel of education it indicated as appearance of difference among the groups among factors of internal quality, marketing quality and symbolic quality of the menu. The average among groups subject to number of consecutive years indicated as there is difference by factors of external quality, internal quality, marketing qualify and symbolic quality of the menu and, the service group between 15~20 years as longer servicing period evaluate lower.

Detecting visual relationships in an image is important in an image understanding task. It enables higher image understanding tasks, that is, predicting the next scene and understanding what occurs in an image. A visual relationship comprises of a subject, a predicate, and an object, and is related to visual, language, and spatial cues. The predicate explains the relationship between the subject and object and can be categorized into different categories such as prepositions and verbs. A large visual gap exists although the visual relationship is included in the same predicate. This study improves upon a previous study (that uses language cues using two losses) and a spatial cue (that only includes individual information) by adding relative information on the subject and object of the extant study. The architectural limitation is demonstrated and is overcome to detect all zero-shot visual relationships. A new problem is discovered, and an explanation of how it decreases performance is provided. The experiment is conducted on the VRD and VG datasets and a significant improvement over previous results is obtained.

Access Control is one of essential branches to provide system's security. Depending on what standards we apply, in general, there are Role-based access control, History-based access control. The first is based on subject's role, The later is based on subject's history. In fact, RBAC has been implemented, we are using it by purchasing some orders through the internet. But, HBAC is so complex that there will occur some errors on the system. This is more and more when HBAC is used with other access controls. So HBAC's formalization and model which are general enough to encompass a range of policies in using more than one access control model within a given system are important. To simplify these, we design the mathematical model called non-access structure. This Non-access structure contains to historical access list. If it is given subjects and objects, we look into subject grouping and object relation, and then we design Non-access structure. Then we can determine the permission based on history without conflict.
