Purpose: This study aims to provide useful information to real estate investors by developing a profit determination model using artificial intelligence. The model analyzes the real estate markets of six selected cities from multiple perspectives, incorporating characteristics of the real estate market, economic indicators, and policies to determine potential profits. Methods: Data on real estate markets, economic indicators, and policies for five cities were collected and cleaned. The data was then normalized and split into training and testing sets. An AI model was developed using machine learning algorithms and trained with this data. The model was applied to the six cities, and its accuracy was evaluated using metrics such as Mean Absolute Error (MAE), Root Mean Square Error (RMSE), and R-squared by comparing predicted profits to actual outcomes. Results: The profit determination model was successfully applied to the real estate markets of six cities, showing high accuracy and predictability in profit forecasts. The study provided valuable insights for real estate investors, demonstrating the model's utility for informed investment decisions. Conclusion: The study identified areas for future improvement, suggesting the integration of diverse data sources and advanced machine learning techniques to enhance predictive capabilities.

Background : Interpretative reporting is an important aspect of laboratory medicine. The large menu of laboratory tests available today makes it increasingly difficult for the non-specialist to order and interpret all laboratory tests. The aim of this study was to determine the usefulness of an expert system to interpret laboratory tests and help physicians order the appropriate tests. Materials and Methods : In order to interpret laboratory tests, a rules-based expert system was developed. In this module, if-then rules were used to interpret the given test result patterns (e.g. urinalysis, anemia, hepatitis B virus, hypercholesterolemia, glucose, syphilis, and tumor markers) and select matching text elements. The system was used to evaluate 535 subjects who visited a health-check program. Results : The overall abnormal rate was 50.5% in the expert system; 34% for cholesterol, 9.9% for urinalysis, 8.0% for anemia, 7.7% for thyroid function tests, 4.5% for tumor marker study, 4.7% for hepatitis virus antigen, 4.3% for serum glucose, and 1.1% for syphilis. Conclusion : These results indicate that the application of the expert system for the interpretation of laboratory tests may provide a useful method for the interpretation of reports. However more rules are needed for the application to in-patients.

Purpose: The purpose of this study was to illustrate the main stream of postmodernism which has influenced theory and research in the nursing science, and then to consider the meaning and value of what the postmodern perspective has meant to nursing science in the 21st century. Method: Derrida and Foucaults philosophical thoughts that characterized postmodernism through the interpretation of their major literature was studied. Based on their philosophy, it was shownhow Derrida's idea could be applied in de constructing the core paradigm in modern nursing science. In terms of Foucault's post-structuralism, reinterpretation of the nursing science in relation to power/knowledge was completed. Result: Postmodernism created multiple and diverse paradigms of nursing theory as well as nursing research. This was accomplished by de constructing the modernism of nursing science which was based on the positivism and medical-cure centralism. Specifically, the post-structuralist perspective revealed issuesaround the relationship of power and knowledge, which dominated and produced modern nursing science. Contemporary nursing science accepts pluralism and needs no unitary meta-paradigm, which can reintegrate multiple and diverse paradigms. Conclusion: In considering the issue of nursing science in postmodernism, it can be summarized as follows: the postmodern thinking discovers and reveals diverse and potential nursing values which were veiled by the domination of western modem nursing science. These were motivated to create nursing knowledge by conversation in interpersonal relationships, which can contribute to practical utilities for the caring-healing situation.

Purpose - Once individuals in an organization don't comprehend with each other's culture and their interaction context differ, there is a bigger danger of poor communication in the organizations. Therefore, people must have a sufficiently comparable interpretation of data, communicative acts and the office itself. For this reason, the purpose of this study is to investigate the relationship between organizational culture and employee communication. Research design, Data, and methodology - The present researcher used categorization matrix development to review data for content. Additionally, the present researcher coded the data to correspond with the identified categories. The role of the categorization matrix is to ensure that the categories hardly represent the concepts and thus validating the findings of the study. Result - The findings from prior resources shows that the role of organizational culture on employee communication satisfaction is a pertinent issue that must be addressed and analyzed to help organizations make the desired profits and productivity. This study provides five solutions between organizational culture and employee communication satisfaction. Conclusion - This study concludes that every employee performs well where they think they are being appreciated and their efforts are rewarded. On the other hand, different organizations have instilled different organizational cultures to ensure they promote the level of satisfaction of their employees in order to yield them an improved employee performance and overall organizational performance.

Purpose : This qualitative study aimed to determine the health problems and thoughts regarding health promotion of residents of the community. Method : Eighteen residents living in S-gu (local area) located in Busan city and health professionals working in health-related workplaces in the area were selected as participants. Focus groups were extracted and composed, and a focus group interview was conducted for six months from November 2015 to April 2016. Data were analyzed using a phenomenological method outlined by Colaizzi. Result : There were 187 significant statements derived from the data obtained from focus group interviews. These statements were categorized into 33 meaning units based on the researcher's interpretation. Thirteen themes were derived from the derived meaning units and finally categorized into five theme clusters: "People who are trapped in," "Health is what you make yourself," "Pathetic health problems in our community," "Finding solutions to health problems," and "Shortcuts to healthy community." Conclusion : The study results can be applied to the identification of a community health problem and the construction of a long-term health promotion system. In future research, it will be necessary to conduct an experimental study on various programs and approaches for promoting community health, which reflects the solutions to the health problems in the community.

Purpose: The purpose of this study is to analyze the measurement results of the financial comprehension test conducted ten times in order to study the financial comprehension. Research design, data, and methodology: In this study, correct answer rates in the Economics and Finance Literacy Certification Test were analyzed across ten rounds of tests taken by 6,662 high school students in Korea. Result: The analysis revealed that Korean high school students' level of financial literacy generally increased as the grade level increased, and the correct answer rates of students at autonomous high schools and special-purpose high schools were statistically different from those of students at general academic high schools and specialized high schools. Conclusion: We can therefore infer that students at specialized high schools face limitations in tackling financial problems due to their lack of proficiency in interpretation and calculation of data necessary for real life financial decision-making. In contrast, students at general academic high schools, special-purpose high schools, and autonomous high schools who do not learn finance as a part of their official curriculum at school were lacking in basic financial knowledge as well as knowledge about the financial system compared to students at specialized high schools, highlighting the need for a measure to address the deficiency.

Objective: As a source of information, medical data can feature hidden relationships. However, the high volume of datasets and complexity of decision-making in medicine introduce difficulties for analysis and interpretation and processing steps may be needed before the data can be used by clinicians in their work. This study focused on the use of Bayesian models with different numbers of nodes to aid clinicians in breast cancer risk estimation. Methods: Bayesian networks (BNs) with a retrospectively collected dataset including mammographic details, risk factor exposure, and clinical findings was assessed for prediction of the probability of breast cancer in individual patients. Area under the receiver-operating characteristic curve (AUC), accuracy, sensitivity, specificity, and positive and negative predictive values were used to evaluate discriminative performance. Result: A network incorporating selected features performed better (AUC = 0.94) than that incorporating all the features (AUC = 0.93). The results revealed no significant difference among 3 models regarding performance indices at the 5% significance level. Conclusion: BNs could effectively discriminate malignant from benign abnormalities and accurately predict the risk of breast cancer in individuals. Moreover, the overall performance of the 9-node BN was better, and due to the lower number of nodes it might be more readily be applied in clinical settings.

As a global effort to conservate the environment, life cycle assessment(LCA) which considers the environmental impact through the life cycle of a product, from acquiring of resources to scrapping, has been actively applied. The LCA is a tool to calculate quantitatively the environmental impacts caused by products or services through their life cycles. The list of numerous data should be analyzed, stored and conducted in order to assess the environmental impacts. Therefore, it is necessary to develop a software for LCA, which can perform the interpretation as well as the environment impact assessment to execute the analysis of such a large number of data effectively. At this time, for the existing some kinds of general LCA softwares, the information about all of input and output should be fed directly and the conclusion is deduced by linking to the database from the public authorized organizations. That makes it possible to evaluate the environmental grades accurately, but it is too slow and difficult for general users to operate and applied it into an electric motor unit(EMU). Therefore, in this research, the basic model was designed, which is based on construction of database structure of the software and organization of architecture, to develop an advanced software for EMU according to user and purpose of it by benchmarking of domestic and international softwares. The result of this study would be applied to develop the LCA software in the future.
