This study was attempted to identify differences in self-esteem and grit in adolescents depending on the type of parenting attitude. Among the Korea Children Youth Panel Survey conducted by National Youth Policy Institute, the data of 2,438 first-year middle school students in 2018 year were analyzed. The collected data were analyzed using hierarchical cluster analysis and k-mean cluster analysis. As a result, the adolescent's perceived parenting attitude was classified into four types: 'passive affection acceptance', 'active affection acceptance', 'authoritarian inconsistency', and 'lack of affection rejection'. Also, there were significant differences in self-esteem and the degree of grit among the four clusters of parenting attitudes. Both self-esteem and grit were highest in the "active affection acceptance" group 2. In the future, differentiated parental education is needed for each cluster to improve self-esteem and grit of adolescents, and this study can be used as a basic data for the development of educational programs.

The purpose of the present study was to compare the long-term management objectives, policy objectives, implementation plans, and detailed plans of four provincial parks established in 2013 using various analysis frameworks. Through this, the study aimed to identify the characteristics of the management plan and extract the implementation plan important to each park by analyzing the priorities in the detailed plan. The long-term management objectives of most parks were to maintain recreational functions by utilizing all the resources of the park, rather than merely preserving the ecosystem. From an ecological perspective, information on major plants and legal protection species are included for most parks, and geological and topographic features considered a major resource. For sustainable forests, it is important to induce the dispersion of concentrated use space. Efficient management systems are distinctively differentiated among the parks. For regional revitalization, the management of programs to link provincial parks and their surrounding areas has become most important. From an ecological perspective, priorities differed for the parks according to their ecological characteristics. For sustainable forests, Moaksan Provincial Park prioritized the visitor reservation system related to the overall park, while the other three parks prioritized alleviating the concentrated use of specific areas. From an efficient management perspective, Daedunsan Provincial Park prioritized aspects related to the cableway. Maisan Provincial Park prioritized inducing the linkage between the use of natural and cultural resources, and Seonunsan Provincial Park prioritized establishing an ecological and cultural commentary operating system. For the base-type leisure activity space, Moaksan Provincial Park prioritized the systematic management and operation of the pilgrimage route, Maisan Provincial Park the connection between the Maisan geography and residents' income, and Seonunsan Provincial Park providing a space for ecological education.

Background: This study aimed to identify the types of adult attachment and determine the relationship between adult attachment and job factors in dental hygienists. Ultimately, it was necessary to identify the need for a secure attachment to improve the quality of clinical dental hygienist's services. Methods: Data of 454 clinical dental hygienists working in dental hospitals or clinics were collected. The research tools consisted of items related to the general and work characteristics of dental hygienists (9 items), adult attachment styles (36 items), organizational commitments (12 items), occupational stress (15 items), and interpersonal relations (18 items). Cronbach's ${\alpha}$ of each tool was ${\geq}0.7$. Results: Most of the participants had fearful attachment styles, followed by dismissing-avoidance, security, and preoccupation. Security was the highest level of organizational commitment according to the adult attachment style, although the differences of the levels were insignificant. For occupational stress, preoccupation was the highest, followed by fearful, security, and dismissing-avoidance, and the differences were significant (p<0.001). For interpersonal relations, security was the highest, followed by preoccupation, dismissing-avoidance, and fearful in order, and the differences were significant (p<0.001). Conclusion: Job stress and interpersonal relation ability according to the adult attachment style of clinical dental hygienists had significant results. Thus, the development of attachment improvement programs by personal style, development of differentiated clinical education and its application, and improvements in the adult attachment styles of clinical dental hygienists would be required rather than simply presenting the needs to collectively improvement the working environment.

Objectives: The study aimed to analyze the factors affecting the maturity of dental biofilm, which was assessed with quantitative light-induced fluorescence-digital(QLF-D), in a sample of Korean older adults. Methods: This cross-sectional study included 67 participants, aged 65 years and older. All participants completed a questionnaire and tests to measure their manual dexterity and handgrip strength, which are parameters that indicate hand function abilities. To evaluate dental biofilm maturity, 804 surfaces of six index teeth were imaged using QLF-D and then quantified as ${\Delta}R$ values. All data were collected from May 25, 2017 to April 30, 2018. The independent t-test, one-way analysis of variance, and step-wise multiple linear regression were performed to analyze the factors associated with the maturity of dental biofilm (${\Delta}R$). Results: The multivariate linear regression analysis revealed that the factor most strongly related to dental biofilm maturity(${\Delta}R$) was manual dexterity (${\beta}=-0.326$), followed by handgrip strength (${\beta}=-0.303$) and use of interdental cleaning devices (${\beta}=-0.283$) (p<0.05). Conclusions: Manual dexterity, handgrip strength, and use of interdental cleaning devices are factors that can predict dental biofilm maturity in adults aged 65 years or older. Therefore, the hand function of a patient should be evaluated first, before assessing the oral hygiene status of the patient or providing him/her with oral health education, and the dental hygienist should provide differentiated oral hygiene care depending on the patient's hand function ability. Finally, dental hygienists should help older adults to recognize the importance of auxiliary oral hygiene devices such as interdental brushes and keep motivating them to use the devices more frequently.

This study analyzes the experiences of a color therapy program that uses color and fashion directing to influence the psychological characteristics of adolescents, such as emotional intelligence, self-efficacy, and color expression. The subjects of this study were 15 adolescents who participated in B-City Winter School (January 6-15, 2020). Pre- and post-tests for emotional intelligence and self-efficacy were conducted to confirm the effect of the color therapy program that indicated a significant difference at the p<.05 level. Statistical significance was confirmed through the GEE model for formal characteristics used in pre/post and fashion-directed color expression. Peter pre- and post-changes in vocabulary emergence were investigated with a Word Cloud analysis using R program 4.0.2 that extracted the lower and upper categories. The significance of this study is that by expressing both color expression and fashion direction together, a program was provided for adolescents to have richer emotional experiences and career-related experiences. This study examined changes within a short period of time in 15 subjects; consequently, a follow-up in-depth qualitative analysis of the program effect and a post-testing study on maintaining the long-term effect is expected to secure further validity and usefulness of the study results. In addition, new studies are expected to contribute to the development of differentiated fashion-related education programs.

The pilot's role is absolutely critical to the safety of an airline. It can be predicted that there is a difference in the acquisition of pilot competency required in actual flight at the initial flight training stage. In this study, the progress and effects of education and training for each background are analyzed, and differentiated competency-based training is to be studied. By sampling a sample of civil airline pilots, we are trying to determine whether there is a difference in the results of the regular proficiency check among the eight competencies defined by ICAO according to military and civil backgrounds. Accordingly, an independent t-test was conducted to test the average difference between the two groups, from the military and civilian origin, to confirm the average difference in the piloting competency between the groups. Based on these results, it will be helpful to design future training courses.

This study explores the possibility that the figure of the Estill Voice Training model, which is based on speech science, can contribute to the expansion of vocal expertise in the acting art where an actor creates a character. The purpose of this study is to examine the usage plan. The training model through the fluidity and structural functionality of the voice production organ is differentiated from the existing voice training that focuses only on the results of sound due to its ambiguous abstraction. Developing the voluntary coordination ability of the occipital region and vocal tract, such as False Vocal Folds, Cricoid Cartilage, Velum, AES, and Anchoring, has scientific efficiency that makes it easier to produce artistic target sounds, and it is a technical skill that can creatively overcome the functional limitations faced by actors. It can be used as a methodology. The Estill model Figure, which is a principle training for harmony and coordination between the elements of voice production, has a practical value that can be used as an alternative training model for the voice education of actors in Korea, where images and abstractions are the mainstream.

This study derives the expressions of vector gravity and gravity gradient tensor due to an elliptical cylinder. The vector gravity for an arbitrary three-dimensional (3D) body is obtained by differentiating the gravitational potential, including the triple integral, according to the shape of the body in each axis direction. The vector gravity of the 3D body with axial symmetry is integrated along the axial direction and reduced to a double integral. The complex Green's theorem using complex conjugates subsequently converts the double integral into a one-dimensional (1D) closed-line integral. Finally, the vector gravity due to the elliptical cylinder is derived using 1D numerical integration by parameterizing a boundary of the elliptical cross-section as a closed line. Similarly, the gravity gradient tensor due to the elliptical cylinder is second-order differentiated from the gravitational potential, including the triple integral, and integrated along the vertical axis direction reducing it to a double integral. Consequently, all the components of the gravity gradient tensor due to an elliptical cylinder are derived using complex Green's theorem as used in the case of vector gravity.

BACKGROUND/OBJECTIVES: The consumption of dietary supplements has shown an increase among young people in their 20s. We aimed to compare the use of dietary supplements and related factors between Chinese international and Korean college students living in South Korea. SUBJECTS/METHODS: We conducted online surveys of 400 Chinese international students and 452 Korean college students from January to February 2021. We analyzed the factors related to the use of dietary supplements by these students using multi-group structural equation modeling and logistic regression analysis. RESULTS: Approximately 65% of the Chinese international students and 93% of the Korean college students consumed dietary supplements at least once in the year preceding the survey. The common types of dietary supplements consumed by both groups of students were vitamin and mineral supplements, Lactobacillus products, and red ginseng products. Structural equation modeling showed that perception of the consumption of dietary supplements by family and friends positively influenced attitude toward dietary supplements. This effect was higher for Korean college students than for Chinese international students (P < 0.01). Attitude toward dietary supplements positively influenced their use, and this effect was higher for Chinese international students than for Korean college students (P < 0.001). Logistic regression analysis showed that the use of dietary supplements by Chinese international students was significantly associated with age, self-reported health status, interest in health, perception of and attitude toward dietary supplements, and length of residence in South Korea. Among Korean college students, it was associated with exercise frequency and attitude toward dietary supplements. CONCLUSION: This study showed significant differences in the use of dietary supplements and related factors between Chinese international and Korean college students. Therefore, nutrition education programs on dietary supplements need to have differentiated content for each group. Such differences also suggest that the industry should consider the relevant characteristics of college students while developing and marketing dietary supplements.
