Due to the lack of visualization services and organic combinations between public and private buildings data, the usability of the basic map has remained low. To address this issue, this paper reports on a solution that organically combines public and private data while providing visualization services to general users. For this purpose, factors that can affect building prices first were examined in order to define the related data attributes. To extract the relevant data attributes, this paper presents a method of acquiring public information data and real estate-related information, as provided by private real estate portal sites. The paper also proposes a pretreatment process required for intelligent machine learning. This report goes on to suggest an intelligent machine learning algorithm that predicts buildings' value pricing and future value by using big data regarding buildings' spatial information, as acquired from a database containing building value attributes. The algorithm's availability was tested by establishing a prototype targeting pilot areas, including Suwon, Anyang, and Gunpo in South Korea. Finally, a prototype visualization solution was developed in order to allow general users to effectively use buildings' value ranking and value pricing, as predicted by intelligent machine learning.

This study analyzes the characteristics of lending-based crowdfunding of various crowdfunding models, identifies the factors affecting the use of the general public, and provides suggestions for the policies set by real estate crowdfunding businesses and related authorities. To analyze the service's adoption from a cognitive perspective, this study developed a new model that combined the Value-based Adoption Model (VAM), motivation theory, and a set of variables that take into account the characteristics of the real estate industry. For empirical analysis, survey was conducted from the general investors of real estate and valid 252 data were utilized by R 3.2.2. The results of this study showed that both government regulation and the perceived risk are hindering the perceived values and intention to use crowdfunding for real estate. In contrast, this research found that among the intrinsic motivation, enjoyment had a significant impact on the perceived value. In addition, it turned out that among the extrinsic motivation, market attractiveness, brand credibility, expected return, and safety and protection had significant impacts on the perceived value. Finally, it showed the perceived value of real estate crowdfunding had a positive impact on the intention to use.

This study focused on analyzing the difference in the impact of non-financial performance, specifically ESG (Environmental, Social, and Governance) activity grade level, on management performance and corporate value among the 25 fashion companies listed on the Korea Exchange that completed their ESG evaluation in 2022. The companies were categorized into three levels based on their ESG evaluations: ESG Integrated Grade (ESG-T), ESG-E (Environmental), ESG-S (Social), and ESG-G (Governance). The study then empirically analyzed how these levels affected management performance and corporate value. The empirical analysis revealed significant differences in the impact on management performance and corporate value depending on the ESG activity grade level. Companies with higher ESG grades exhibited better management performance and higher corporate values across all ESG sub-variables (ESG-T, ESG-E, ESG-S, ESG-G) compared to those with lower grades. This finding demonstrates the influence of ESG activity grade levels on improving management performance and enhancing corporate value in fashion companies. The results of this research provide meaningful insights into the direction of sustainable management through ESG activities in fashion companies.

Purpose: Transverse type or volar oblique type of defect of thumb tip can be covered by Moberg flap or second toe pulp free flap. We compared these two methods in functional result, patients' satisfaction, and sensation, etc. to find a better way to cover the defect of the thumb tip. Methods: From 2003 to 2006, we chose the patients randomly with preoperative pictures. The patients had the defect of the thumb tip which is either transverse or volar oblique type. The 6 patients were treated with Moberg flap and other 6 patients were treated with second toe pulp free flap. We have analyzed the results by 2 point discrimination, side pinching power test, pulp to pulp pinching power test, pain scales (visual analogue scale), satisfaction scales of the patients (functional and aesthetic), the degree of the range of motion, etc. Results: All flaps survived without any complications. In the cases of Moberg flaps, the value of static 2 point discrimination test was 5.6 mm, and the value of moving 2 point discrimination test was 4.8 mm. In the cases of second toe pulp free flaps, the values were 9.6 mm and 9.3 mm. In the cases of Moberg flaps, the value of the Side pinch power test was 6.6 kg, 4.4 kg. In the case of second toe pulp free flaps, the values were 4.8 kg and 2.5 kg. The value of aesthetic satisfaction scale of the patients in Moberg flaps was 5.6, the value of functional satisfaction scale of the patients was 3.6. In cases of second toe pulp free flaps, the values were 5.6 and 3.6. The active range of motion of Interphalangeal joint in the cases of Moberg flaps was 46.6 degree, and the active range of motion of metacarpophalangeal joint was 55 degree, in the cases of second toe pulp free flaps, the values were 36.6 degree and 59 degree. Conclusion: As a result, when the defect of the thumb tip is transverse or volar oblique type, we suggest that the operators choose Moberg flap to cover the defect of the thumb tip.

This exploratory research explores the concept of a digital legacy as a general concept and as a collection of digital possessions with unique characteristics. The results reported in this article are part of a larger study. In Cushing (2013), the author identified the characteristics of a digital possession. In this study, these characteristics of a digital possession were utilized to explore how the characteristics of several digital possessions could form a collection, or a digital legacy. In addition to being explored as a collection of digital possessions, data was collected about the general concept of a digital legacy. In part I of the study, 23 participants from three age groups were interviewed about their general concept of a digital legacy. Five general characteristics describing a digital legacy were identified. In part II of the study, interview data from Cushing (2013) was used to create statements describing digital possessions. The statements were classified utilizing the archival concept of primary and secondary values, as well as the consumer behavior concepts of self extension to possessions and possession attachment. Primary value refers to the purpose for which the item was created, while secondary value refers to an additional value that the participants can perceive the item to hold, such as a perception that an item can represent one's identity. Using standard Q method procedure, 48 participants were directed to rank their agreement with 60 statements (written on cards), along a distribution of -5 to +5, according to the characteristics of the digital possession they would most like to maintain for a digital legacy. The ranked statements were analyzed using Q factor analysis, in order to perceive the most common statements associated with maintaining digital possessions for a digital legacy. Q method results suggested that most individuals described the digital possessions they wanted to maintain for a digital legacy using various combinations of characteristics associated with primary and secondary values. This suggests that while some participants will respond to personal archiving based on the concept of preserving identity (a perceived secondary value), this will not appeal to everyone. Information professional could consider this difference in appeal when marketing personal archiving assistance to patrons.

The healthcare environment today is changing rapidly with factors of healthcare consumers in selecting medical institutions also altering at a fast pace under the circumstances. In this study, the theory of consumption values established by Sheth in 1991 is adopted in order to examine particular value affecting consumer selection of healthcare institutions. For the purpose of this study, healthcare consumers were surveyed using questionnaires developed based on the five values of Sheth supplemented by value of effort to acquire hospital information and value in health. Consequently, 24 consumption values affecting selection process were confirmed through discriminant analysis. As a result of regression analysis on factors affecting consumer selection of healthcare institution, effort to acquire hospital information and age among demographic characteristics of respondents are determined important predictors for consumer selection of general hospitals over clinics or small-sized hospitals. Further, service, reputation scale of healthcare institution among functional values and importance of health and effort to acquire hospital information among value in health are identified as significant predictors for consumer selection of large-sized general hospitals over clinic or small-sized hospitals. This study suggests not only vital implications for marketing strategy of healthcare institutions, but also methods to promote positive image for healthcare providers. In addition, this study closely examines the cause of the leaning phenomenon of healthcare comsumers toward large-sized general hospitals.

Purpose: The study was done to verify evidence-based practice (EBP) readiness and factors contributing to EBP competency in general hospital nurses. Methods: Participants were 219 nurses working in 7 general hospitals in G-city and J Province. Data were collected from May 12 to May 28, 2015 and analyzed using one-way ANOVA, Pearson's correlation and stepwise multiple regression. Results: Mean score for EBP competency was $3.89{\pm}0.83$, for critical thinking disposition, $3.35{\pm}0.36$, for EBP attitude, $3.53{\pm}0.66$, for beliefs about value of EBP, $3.42{\pm}0.56$, for ability in research performance, $2.86{\pm}0.57$, for time to devote to EBP, $2.57{\pm}0.69$ and for organization support for EBP, $3.36{\pm}0.46$. EBP competency was significantly correlated with critical thinking disposition (r=.37, p<.001), beliefs about value of EBP (r=.43, p<.001), ability in research performance (r=.44, p<.001), and time to devote to EBP(r=.33, p<.001). Factors influencing EBP competency in general hospital nurses were research performance (${\beta}=.29$, p<.001), beliefs about value of EBP (${\beta}=.24$, p<.001), critical thinking disposition (${\beta}=.15$, p=.014), recognition of EBP (${\beta}=-.18$, p=.002), which together explained 35% of total variance. Conclusion: Findings indicate that introduction and activation of EBP in general hospitals is essential and development of systematic training programs to strengthen critical thinking disposition and EBP competency are needed.

In this paper, both an approximate expression and an exact expression for the contribution factor of an element to the natural frequency of the finite element discretized system of a structure in general and a membrane in particular have been derived from the energy conservation principle and the finite element formulation of structural eigenvalue problems. The approximate expression for the contribution factor of an element is used to predict and determine the elements to be removed in an iteration since it depends only on the quantities associated with the old system in the iteration. The exact expression for the contribution factor of an element makes it possible to check whether the element is correctly removed at the end of an iteration because it depends on both the old system and the new system in the iteration. Thus, the combined use of the approximate expression and the exact expression allows a considerable number of elements to be removed in a single iteration so that the efficiency of the evolutionary structural optimization method can be greatly improved for solving the natural frequency optimization problem of a structure. A square membrane with different boundary supports has been chosen to investigate the general evolutionary path for the fundamental natural frequency of the structure. The related results indicated that if the objective of a structural optimization is to raise the fundamental natural frequency of the structure to an optimal value, the general evolutionary path during its optimization is that the elements are gradually removed along the direction from the area surrounded by the contour of the highest value to that surrounded by the contour of the lowest value.
