Background: To improve muscle flexibility, static stretch is the most common type and is considered safe and effective for improving overall flexibility of muscles. During the stretch, the intensity is more likely to be determined by the degree of an athlete's pain and practitioner's skills rather than quantitative measures of stretch. It is necessary to determine the optimal intensity for the stretch. Objects: The purpose of this study is to explore the relationship between hand held dynamometer (HHD) and verbal rating scale (VRS) in comparison of the effects of continuance time on active (walking) and inactive (sitting) movement after static stretch. Methods: A cross-sectional study was conducted with a sample (n=62) recruited from a university. Participants were randomly assigned to 2 different groups (n=31 for each group) based on participants' positions either remaining in sitting or freely walking around for a series of re-assessments. Data was collected at pre-warm up, pre-stretch, post-stretch, and additional assessments at the time of 3, 6, 9, 12, 15, 20 and 30 minutes after the stretch. Results: Relationship between VRS and HHD scores represents very weak correlation (Spearman's p=-.16, p>.05). Pearson's correlation analysis was conducted following the logarithmic transformation of the two scores. Pearson's correlation after the transformation still showed a very low relationship and a poor linear relationship between the two scores (Pearson's r=-.18, p>.05). Conclusion: The optimal intensity for stretch cannot be solely determined by the subjective pain perception. The objective measurement such as HHD could be used in conjunction with the pain perception.

This study was undertaken to find out the perception of marital relationship and to understand the typology. The Q-population consisted of 153 statements that were collected and 33 Q-samples were selected. The P-samples for this study were made up of 30 who were married. Each responded to a Q-set of marital relationship according to 9-point scale. The results of Q-sorting were coded and analysed using QUANL PC program. Typological observations were as follows. 1) One in body and spirit type : In type 1, couples had different backgrounds respectively but felt one in body and spirit. 2) Companionship type : 2. Couples had not so much a hierarchial as a horizontal relationship. Couples perceived themselves as interdependent and friends. 3) Adaptation type : Couples readily adapted themselves to a marital relationship. They only depended on their spouses at times and stressed the relationship. Marriage was accepted as destiny rather than choice. On the basis of these results, we suggest: When a marriage is in trouble, that we assess the type of marital relationship in advance and intervene with a proper program. In addition, practical intervention programs need to be developed tailored to the type of subjective perception about the marital relation

The purpose of this study is to provide a basic data of clothing development which can improve the satisfaction of the body shape by examining the subjective evaluation and type characteristics of the old-old women themselves. Q methodology was used for the study of subjectivity. The types of the body shape of the old-old women were analyzed as five types: bent body with protruding abdomen, backward bent body with slender legs, inverted triangle, swollen cylinder, triangle. The bent body with protruding abdomen had a bent back and waist. They were recognized that the bust and shoulders were sagging and abdomen was protruding. The backward bent body with slender legs was the smallest of the five types with a BMI index and shoulders and bust were sagging. And knee and waist were bent and legs were thin. The inverted triangular shape showed the highest BMI index among the 5 types, indicating that it is obese. They thought that the upper body was developed and the lower body and legs were slender. The swollen cylinder shape was analyzed to be the smallest and the most fat body. The triangle shape had developed lower body and bent back and waist. It is considered that a design consideration is needed to cover the disadvantages of the body shape in consideration of not only wearing feeling but also aesthetic part when making clothes. By making ergonomic garments considering the characteristics of body shape, it can be expected to change the body shape due to the wearing of clothing that is not suitable for body shape and the effect on physical health in a positive direction.

PURPOSE: The primary objective of this study was to develop a virtual reality-based vestibular rehabilitation system to enhance balance perception, target rehabilitation specialists, and evaluate its usability. A key goal was establishing a system refinement strategy based on the collected data. METHODS: We conducted a study involving ten adults aged 10 to 29 in Gwangju Metropolitan City to evaluate the usability of a virtual reality-based vestibular rehabilitation system to enhance balance perception. After introducing the product and explaining its use to the participants, balance assessments and training were conducted using computerized dynamic posturography (CDP) (also called the test of balance [TOB]). Subsequently, participants were given a questionnaire to evaluate subjective stability, operability, and satisfaction. Frequency analysis was utilized to determine the frequency of the variable values of the measurement items in the survey for descriptive statistics. RESULTS: We found that the average usability score was 2.587. When broken down by category, stability received an average rating of 2.725, operability scored an average of 2.783, and satisfaction averaged 2.454. These findings suggest that most participants experienced positive sentiments and considerable satisfaction. CONCLUSION: The study successfully developed a virtual reality-based vestibular rehabilitation system, which was an improvement over the previous model and addressed its shortcomings. The results show that users with vestibular impairments are satisfied and more engaged with this system, indicating that additional studies are warranted.

The purpose of this study was to show the possibility of labor mobility among married women by analysing some variables to have effects on their employment status and willingness to move in the labo market, namely, whether they would willingly enter into/come out the labor market. The personal collecting data were used and one discirminant function and two probit models were employed to analyse the efficients to the independent variables. The resets of this study were as follows. The very discriminant variables to have significant effects on the employment status of married women were the age of the youngest and the number of children. The willingness to enter into the labor market of unemployed married women was high in contrast as the willingness to keep the job was high among employed married women. The subjective perception on their own health, children related variables, and financial variable were very significant to predict the possiblities to move in the labor market among married women. It was remarkable that the psychological variables, which were related with the attitudes toward the occupation of house wife and employment of married women, were also important. These results showed that first of all, the decision of whether they enter into or come out in the labor market among married women is largely on the basis of the household situation not on the personal capacities of married women themselves.

The purposes of this study were to understand the oral health promotion behavior and dental health condition of primary school children and to examine the relationships between the two variables. For that purpose, 729 fifth and sixth graders from four primary school located in Seoul were surveyed. In addition to the survey responses, dental examination results were used for analysis. The findings were as follows: 1. The children scored 3.51 out of full 5 points in oral health promotion behavior. they scored the highest at 3.82 in dietary habits, which were followed by going to a dentist for prevention purposes at 3.43, the method and frequency of brushing teeth at 3.40 and the use of fluorine at 3.39. 2. It turned out that 46.9% of the children had decayed permanent teeth. The number of decayed teeth was $1.66{\pm}2.32$, that of missing teeth was $0.03{\pm}0.24$. 3. There were reverse correlations(r = -0.32) between the children's subjective perception of their dental health condition and decayed teeth. The more positive perceptions they had for their own dental health condition, the less decayed teeth they had(p < 0.01). 4. There were also reverse correlations(r = -0.10) between the children's oral health promotion behavior and decayed teeth. The more they were engaged in Behavior of alimentation, the less decayed teeth they had(p < 0.01). The results indicate that primary school children can keep their dental health by practicing the right oral health promotion behavior, which calls for a need to develop and apply dental health education programs to promote the oral health promotion behavior among primary school children.

This study aims to investigate the appropriate volume of artificial ventilation and success rate when Basic - emergency medical Technician administer bag valve mask(BVM) artificial ventilation to patients experiencing respiratory failure or respiratory arrest using a respiratory rate measurement device. The research was conducted from December 11th to 12th, 2023, targeting 20 Basic - emergency medical Technicians enrolled at D University. Ten participants were selected for the experimental group, receiving BVM ventilation training with the use of a respiratory rate measurement device, while the other ten were assigned to the control group, receiving BVM ventilation training without the use of a respiratory rate measurement device. The experiment involved providing artificial ventilation for 2 minutes. The results of the study indicated that the control group did not provide accurate tidal volume (p=.025). The experimental group demonstrated a higher success rate of ventilation over the 2-minute period, while the control group showed a significant difference (p=.001). Subjective perception of tidal volume and objectively measured tidal volume also exhibited a significant difference in the control group (p=.010). Therefore, training with a respiratory rate measurement device can align the subjective perception of tidal volume with objective measurements, increase the success rate of ventilation, and potentially contribute to improving survival rates in patients experiencing respiratory failure or respiratory arrest during cardiopulmonary resuscitation.

The purpose of this study was to assess the relationship that adolescent stress perception level has with dietary habits and oral health behaviors in high school students. A survey of high school students in some areas of the Jeollabuk-do province of South Korea was conducted. Five hundred fourteen survey responses were used in the final analysis. As a result of the questionnaire survey, the following conclusions were obtained. The highest stress type was indicated to be academic stress (mean${\pm}$standard deviation [SD], $3.09{\pm}0.89$). The next was shown to be home (family) stress (mean${\pm}$SD, $2.85{\pm}0.84$). The possibility of using a dental clinic was indicated to be less in girls than boys (p<0.001). Regarding subjective oral health behavior, the possibility of visiting a dental clinic was low in those who thought that their own oral health condition was not good or moderate (p<0.05). Also, it was shown that the higher stress led to the higher possibility of visiting a dental clinic (p<0.01). Students with higher grades had a in the upper ranks were indicated to have high possibility of having a regular meal (p<0.01). Higher stress led to the significantly higher possibility of eating cariogenic food (p<0.01). Students with median grades had a high possibility of eating cariogenic food (p<0.01), while students with higher grades had a low possibility of eating cariogenic food (p<0.05). These resultss show that stress perception level influences dietary habits and oral health behaviors. Thus, there is a need to develop a program in high scholls to promote the physical and mental health of students to relieve stress. Substantial and systematic oral health education is thought to be likely needed to develop desirable dietary habits.

The purpose of this study was to investigate how employed dental hygienists (graduates) and alumni are aware of dental health insurance and how to organize their classes for running efficient dental health insurance courses, and therefore to suggest opinions on the introduction of professional dental hygienist qualifications. The analyses was carried out using IBM SPSS Statistics 24.0. Sixty-nine students (56.1%) preferred one semester dental health insurance course as two semester courses and 63 students (51.2%) preferred theoretical course as practical course. Ninety-six (78%) students preferred dental health insurance claimants as others for their most necessary certification. Ninety-three dentists (75.6%) thought of the dental hygienist as the appropriate occupation for dental health insurance claims. The correlation coefficient was significant at the 0.01 level (both sides) and all showed a positive correlation. The effect of subjective understanding of dental health insurance and the perception of dental health insurance claim on students' intention to complete those courses explained 32% of the response, and the effect of the intention to complete those courses on the willingness to earn a certificate explained 22.3%. This study reveals the willingness of students to complete those courses to acquire qualifications in order to achieve a competitive advantage in employment, and suggests the necessity of institutional improvements such as changing the method of dental insurance education, varying the class time distribution, and introducing dental health insurance professional dental hygienist qualification in the country.

In order to evaluate the factors related to therapeutic compliance of hypertensive patients in small and medium scale industry, the questionnaire survey and the blood pressure measurement were performed on 138 hypertensive patients who were reported to have C or $D_2$ result of hypertension at the workers' periodic health examination from March to November 2001. The contents of questionnaire included the informations of factors related to therapeutic compliance of hypertensive patients such as, age, sex, marital status, income, education levels, scale, occupation, work duration, smoking and drinking habits, exercise, family history, stress and A type personality, employer's concern, organizational culture, health status, awareness, knowledge and attitude toward the needs of hypertension treatment, and experience of health education. The results of the study were as follows: 1. The proportion of those who were compliant to the treatment of hypertension was 41.3% of subjects. Among small scale industry less than 50 employees, the rate of therapeutic compliance group was 27.5% and therapeutic noncompliance group was 72.5%. Among medium scale industry more than 50 employees, the rate of therapeutic compliance group was 60.3% and therapeutic noncompliance group was 39.7%. 2. Among therapeutic noncompliance group, 95.1% of patients were aware of the fact that workers have hypertension, and 77.8% of patients got 6-10 marks of hypertension related knowledge. For health education, 27.2% were experienced and 34.6% said no intention to participate. And for hypertension treatment, 9.9% said no need to get the treatment and 44.4% said have no idea whether get treatment or not. 3. The significant factors related to therapeutic compliance of hypertensive patients in small scale industry were work duration, A type personality(anger), health status, attitude toward the needs of hypertension treatment, and experience of health education. 4. The significant factors related to therapeutic compliance of hypertensive patients in medium scale industry were age, occupation, subjective symptom, attitude toward the needs of hypertension treatment, and experience of health education. In consideration of above findings, it was suggested that in order to improve the therapeutic compliance in small and medium scale industry hypertensives, it be necessary to change attitude, perception, knowledge and treatment of hypertension by various methods such as effective health education and individually consulting programs by occupational health professional.
