This study investigated the factors associated with HINT-8 (Korean health-related quality of life instrument with eight items), including health habits, hand grip strength, chronic disease, chewing function, mental health, and nutrient intake. In this study, the health-related quality of life (HRQoL; HINT-8) was assessed using the data from the 2019 Korea National Health and Nutrition Examination Survey (KNHANES VIII) among Koreans aged over 65, with HINT-8 being evaluated based on the general characteristics. Of the participants from KNHANES VIII, 1,455 subjects were analyzed using SPSS statistics complex samples (Windows ver. 27.0). The HINT-8 score was significantly lower in females and in those aged 75 years or older, lowest educational level, lowest income level, and single households. Logistic regression analysis, adjusted for the general characteristics, revealed a significant association between a lower HINT-8 group and various factors: low aerobic physical activity (OR=1.71, 95% CI=1.25~2.35), low hand grip strength (OR=1.34, 95% CI=1.02~1.78), chewing difficulties (OR=2.17, 95% CI=1.62~2.92), poor self-rated health status (OR=6.11, 95% CI=4.42~8.45), stressful mental status (OR=3.57, 95% CI=2.27~5.63) and poor calcium status (OR=1.45, 95% CI=1.11~1.88). On the other hand, this study could not reveal a significant association between a lower HINT-8 group and factors such as smoking, drinking, chronic disease, and nutrient intake status, except for calcium intake. This study suggests that HINT-8 is associated with aerobic physical activity, hand grip strength, chewing function, mental health, and calcium intake, but not with smoking, drinking, chronic disease, and nutrient intake.

The aims of this study were to understand and to predict the determinant factors affecting the exercise behaviors and physical fitness by testing the Ponder's health promotion model, and to help the patients with rheumatoid arthritis and osteoarthritis perform the continuous exercise program, and to help them maximize the physical effect such as muscle strength. endurance, and fuctional status and mental effects including self efficacy and quality of life, and improve the physical and mental wellbeing, and to provide a basis for the nursing intervention strategies. We analyzed the clinical records of 208 patients with rheumatoid arthritis and degenerative arthritis who visited the outpatient clinics at H university hospital in Seoul between October 5, 1999 and October 24, 1999. Data were composed of self reported questionnaire and good of fitness score which were obtained by pedalling the ergometer of bicycle for 9 minutes. SPSS Win 8.0 and Window LISREL 8.12a were used for statistical analysis. 24 Of 54 hypothetical paths were supported in modified model, which was considered as a proper model with improved fit index. The physical fitness was directly influenced by exercise participation behavior and education level, and indirectly by physical fitness, while fatigue, physical disability, pastexercise behavior, life-style, self-efficacy, which explained 20% of physical fitness. The exercise participation were directly influenced by perceived benefits and self-efficacy, and indirectly influenced by life-style, fatigue and physical disability, and directly and indirectly by past exercise behavior, which explained 53% of exercise participation. Exercise score were directly affected by perceived health status, perceived benefits, self efficacy, and past exercise behavior, and were indirectly affected by fatigue, physical disability, and life-style, which explained 50%. Perceived health status were directly influeced by level of education, depression, sleep disorder, and physical disability, which explained 34% of perceived health status. Perceived benefit was directly influenced by fatigue, sleep disorder, physical disability, and life-style, which explained 45%. Perceived barriers was directly influenced by fatigue, sleep disorder, and lifestyle, which explained 9%. Self- efficacy was directly influenced by fatigue, physical disability, past exercise behavior, and level of education, which explained 61%. In conclusion, important variables for physical fitness were exercise participation and level of education, and variables affecting exercise participation were perceived self-efficacy, benefits, and past exercise behavior. Perceived self-efficacy of exercise was a significant predictor of exercise participation. Life-style, fatigue, and physical disability showed direct effects on perceived benefit, perceived barriers, and self-efficacy, and indirect effects on exercise behavior. Therefore, disease related factor should be minimized for physical performance and well being in nursing intervention for patients with rheumatoid arthritis, and plans to promote and continue exercise should be soaked to reduce disability. In addition, Exercise program should be planned and performed by the exact evaluation of exercise according to the ability of the patients and the contents to improve the importance of exercise and self efficacy in self control program, dedicated educational program should be involved.

[Purpose] The purpose of this study was to assess changes in blood glucose level, blood pressure, and arterial stiffness after a 75 g oral glucose tolerance test (OGTT) in elderly women aged over 65 years with hypertension and either normal glycemic control, impaired fasting glucose tolerance, or diabetes mellitus. We also wished to investigate the relationship between stages of diabetes and physical fitness. [Methods] A total of 24 elderly women with hypertension were assigned to a control group (CON; n=7), impaired fasting glucose group (IFG; n=9), and diabetes mellitus group (DM; n=8). In each group, blood glucose level, brachial ankle pulse wave velocity (PWV), and blood pressure were measured at baseline as well as 60 and 120 minutes after a 75 g OGTT. Physical fitness factors such as hand grip strength, balance test, 4 m gait speed test, chair stand test, short physical performance battery, and 6-minute walking test were subsequently assessed. [Results] In all three groups, blood glucose levels were significantly increased at 60 and 120 minutes after a 75 g OGTT. In the DM group, blood glucose levels were significantly higher before and after a 75 g OGTT than in the CON group. In the CON group, PWV was significantly increased at 60 minutes after a 75 g OGTT; however, there were no changes in other groups after glucose ingestion. In the CON group, systolic and diastolic blood pressures were significantly decreased at 60 and 120 minutes after a 75 g OGTT compared to baseline. However, there was no change in blood pressure after ingestion in the DM group. The IFG group had greater grip strength than the CON group; however, there were no differences in other variables between the groups. [Conclusion] After a 75 g OGTT, elderly women with hypertension and diabetes maintain higher blood glucose levels compared to those with hypertension alone. Unlike elderly women with hypertension alone, those with hypertension and diabetes did not show changes in arterial stiffness and blood pressure after a 75 g OGTT. Therefore, elderly women with hypertension and diabetes may not be able to control their blood vessels following a 75 g OGTT due to impaired vascular endothelial function. Moreover, there was no association between diabetes stage and physical fitness in elderly women with hypertension.

It is impossible for all athletes to be satisfied with a single training program due to the fact that they have different physiological characteristics and needs. However, paucity studies have been introduced a specific training program for high school sprinters. Therefore, this study was designed to help develop and introduce the training program with a physical examination to enhance sprinting performance for experienced high school sprinters. VO2max, muscular strength, basic physical ability, and body composition were measured before and after a 24 week training program. The following are the conclusions based on the results of this study: 1) body fat percentage was increased after 24 weeks of training. Fat free mass and the amount of water in the body increased by 1.5% and 1.1% respectively, 2) $VO_2$maxand anaerobic threshold level showed a significant increase after 24 weeks of training, 3) exercise duration and anaerobic threshold duration were also increased after 24 weeks of training, but not statistically significant, and 4) muscular strength significantly increased due to the execution of combined weight training and circuit training. Development and implementation of the training program in this study made sprinters' physical capacities better in VO2max, anaerobic threshold, and muscular strength and body composition. Also, sprinters were able to increase fat free mass through 24 weeks of training due to increased muscle mass. Therefore, a training program for high school sprinters should include a physical examination to enhance sprinting performance and prevent sports injuries.

Purpose : The purpose of this study was to investigate the effect of abdominal muscle strengthening exercise on abdominal muscle strength and respiratory function in stroke patients. Methods : The subjects were 14 stroke patients (10 males, 4 females) hospitalized at W rehabilitation hospital in Busan City and randomly assigned to 7 exercise groups and 7 control groups. Exercise was performed in combination with an upper and lower extremity pattern of proprioceptive neuromuscular facilitation. Measurements of abdominal muscle strength and respiratory function were made before intervention and 4 weeks after intervention. Abdominal muscle strength was assessed using a digital manual dynamometer, and respiratory function was assessed by spirometry. The collected data were analyzed with a paired t-test and independent t-test and the significance level was set as α =.05. Results : The results showed that applying abdominal muscle strengthening exercise to stroke patients showed a significant increase in abdominal muscle strength and a significant difference between groups (p<.05). Maximal-effort expiratory spirogram (MES) readings were significantly increased in forced vital capacity (FVC), and forced expiratory volume in one second (FEV₁), in the exercise group, and there were a significant differences between the groups in terms of FEV1 (p<.05). Slow vital capacity (SVC) was significantly increased in vital capacity (VC), tidal volume (TV), inspiratory reserve volume (IRV), and expiratory capacity (EC), and there were significant differences between the groups in VC, TV, expiratory reserve volume (ERV), EC, and inspiratory capacity (IC) (p<.05). Conclusion : Abdominal muscle strengthening exercise was effective in the abdominal muscle strength of stroke patients, and it was confirmed to have a positive effect on the enhancement of respiratory function. Therefore, it seems that exercise programs for stroke patients with respiratory weakness should include abdominal muscle strengthening exercises.

In order to investigate the applicability of lyocell fiber to filter paper, papper sheets were manufactured with the addition of lyocell fibers in various length(1.5 denier: 2, 3, 4mm) and content(10, 30, 50%) and their physical characters, such as fibrilation rate, adsorption efficiency of methylene blue(MB), paper formation, and crimping ability, etc, were tested. The level of main fibrilation from lyocell fiber was higher in wet beating process than that in free beating because of the higher strength of lyocell fiber compared with wood fiber. Fibrilation could be observed at the degree of beating over 30$^{\circ}$ SR in wet beating with Valley beater. The air permeability and tear factor of the paper increased and the paper formation index decreased according to the increase of fiber length. The weak binding force of lyocell fiber in spite of its higher fiber strength, might be a limitng factor in addition of lyocell fiber to the natural wood pulp in manufacturing the paper having the needed physical properties. High contents of wood pulp decreased air permeability, the breaking length, tear factor, the bursting strength, and paper formation index in paper sheets. As the contents of lyocell increased from 10% to 100%, the adsorption efficiency of MB was elevated to 1.7-7.9 times compared with that in 100% wood pulp. But the length of lyocell fiber did not affect the MB adsorption.
