Objective: The study focuses on saliva, which is one of the most important factors controlling oral health, was performed in order to know the relationship between the influencing factors. Methods: Specifically, in terms of caries experience, periodontal index, salivary secretion and viscosity, pH, sugar content, intra-oral moisture absorption and salivary microbes, were analyzed for the correlations between these factors in each age group including preschool children, children, adolescent, adult, prime of manhood and the elderly. Results: In children, among intra-oral salivary microbes, bacilli and filamentous micro-organism are negatively correlated with caries experience. The moisture absorption on the dorsum of the tongue is positively correlated with the amount and the motility of spiral type of the micro-organism. In adolescent, The salivary viscosity was correlated with caries experience, pH and sugar content. Sugar content and pH are also correlated. Among oral salivary micro-organisms, the more the bacilli and filamentous microbes were existence, the less the caries experience. In Young adults, salivary viscosity and sugar content were correlated with un-stimulated and stimulated salivary flow. Sugar content and viscosity were also correlated. As for salivary micro-organism, the more appear of the cocci, the higher of the sugar content. In prime of the manhood, the flow of stimulated saliva is correlated with the amount and motility of spirilla, bacilli and filamentous type of the micro-organisms. It showed a positive correlation with sugar content and viscosity. The moisture absorption on the dorsum of the tongue was correlated with sugar content and that on the sublingual part with viscosity. Conclusion: Correlated factors found in this study differ by depending on age groups. Some representative factors can be estimated to be predictable by measuring for other factors and it can be applied for prevention-based incremental oral health care, in clinical.

The purpose of this study is to verify the effect of the average wage per employee on business performance of lodging companies. Human resource is one of the most important core competencies of the companies, and human resource management of lodging companies, which is a labor intensive service industry, will be more important. This paper focuses on wage, which is a representative item related to human resource. Analysis of 2,515 firm-year from 2000 to 2017 showed that the relationship between the average wage per employee and business performance appeared to be positive. All analyses, such as correlation, univariate, and regression reported consistent results. It appears that high wage served as a motivation for employees of low-paying lodging companies, and therefore, performance has improved. Despite the importance of the study of employees, which constitutes a large part of the companies, only a fragmentary study of a particular hotel company has been made while little research on the entire lodging business has been conducted due to the limitations of data collection. This study is meaningful in that it has verified the relationship between the average wage per employee on business performance for the externally audited lodging companies. Lodging companies will need to make efforts to improve their performance through appropriate compensation to their employees.

This paper aims to analyze the effect of CEO characteristics of lodging companies on CSR. CEO characteristics are one of the most important factors influencing corporate activities. Since the management behavior of companies may vary depending on CEO characteristics, it is meaningful to study how the CSR activities of lodging companies change depending on the nationality and number of CEO. The sample of this study is based on externally audited companies that fall under the " lodging industry" in the medium industry classification of the Korea Listed Companies Association from 2000 to 2020. The result shows that lodging companies with foreign CEOs perform more CSR than those with Korean CEOs. It is found that lodging companies with multiple CEOs perform less CSR than those with a single CEO. This paper is meaningful in that it studied CSR activities such as ESG management in connection with CEO characteristics of lodging companies. In particular, it differs from previous studies in that it studied the nationality and number of CEOs rather than the demographic characteristics of CEOs for which many studies have been conducted.
