  • Purpose: The study was to develop psychoeducational intervention and identify its effect for symptom management of home cancer patient. Method: Study subjects were 24 patients in control group and 18 patients in experimental group. In experimental group, individualized psychoeducation was done after pretest and then continued to educate and consult through calling by telephone once a week for 4 weeks. The data were collected using several tools such as symptom distress by McCorkle(2000). Physical functioning, a part of Medical Outcome Study by Ware and Sherbouine(1992) and QOL- cancer patient version by Ferrell and Grant(1995) from 18th of Feb. to 30th of July. Data were analysed to ${\chi}^2$ test and t test using SAS VER8.12. Results: The mean score of symptom distress was 21.6 in experimental group and 24.2 in control group. Experimental group was shown lower score than control group. Physical functioning of experimental group was better as mean score 23.3 than 20.6 in control. Psychological wellbeing was 69.7 in experimental group and 66.1 in control group. Social wellbeing was 32.2 in experiment and 25.8 in control. Psychosocial wellbeing of experimental group was higher than control group. However there was no significant differernce between two groups among these variables. Conclusion: The psycho educational intervention was not made symptom mangement, physical functioning, and psycho social wellbeing improved but shown positive tendency. It is expected having a statistically significant finding if enlarged sample size and prolonged the intervention term in future. Therefore it is suggested psycho educational intervention study do repeatedly.

  • With a view to developing male dress forms for educational purposes, human body measurement was made for male adults in their twenties residing in Busan, Korea. Based on the results, the following conclusion was obtained: 1. Comparison d the measurement in Busan and the data of the 5th Korean physical dimensions(Size Korea) In the comparison of the Busan male adults in their 20s with national physical dimensions(Size Korea) by way of the Mollison relational deviation line, all the 28 items revealed differences less than 0.7. As the Busan sample reflects the body type d the average Korean men in their 20s, Busan's measurement results can be safely used as the data for dress form development. 2. Results of front body type classification According to the factor analysis, seven factors of the front body type were produced to explain 77.25%. The factors were shoulder angles, waist height, hip shapes, chest shapes, proportion of body(chest, waist, hip)width to shoulder width and so on. Cluster analysis brought about three somatotype groups. First, the body type with the least differences in hip-waist width, shoulder-waist with, and hip angles (24,23% in appearance) was named Type H. Second, the body type with the most chest-waist width and hip angles (38.66% in appearance) was called Type Sam X Third, the body type with the greatest shoulder-chest width, shoulder-hip width, and shoulder angles (37.11% in appearance) was termed Type Y.

  • Background: Although the original version of the health-related quality of life (HRQOL) questionnaires are found to be acceptable, the cross-culturally adapted versions may not be comparable to their original version. Objects: To examine dimensionality and construct validity of two Korean versions of the brief version of the World Health Organization Quality of Life (WHOQOL-BREF) and EuroQOL-5 dimension (EQ-5D) questionnaires. Methods: A total of 77 cancer survivors undergoing palliative rehabilitation programs from two rehabilitation institutes was recruited from April 16, 2018 to June 26, 2019. The WHOQOL-BREF and the EQ-5D were filled out by the various cancer survivors following a particular session of rehabilitation programs. The scores were analyzed with Winsteps Rasch analysis computer program using the rating scale model. Rasch fit statistics were used to determine the dimensionality and the item difficulty calibrations of WHOQOL-BREF and EQ-5D. Results: All items except two, negative feeling, need treatment function and pain prevent activity (mean square [MnSq] = 2.42, 1.82 and 2.51, respectively), were found to be acceptable, while two items of the EQ-5D, anxiety/depression and self-care, were misfit (infit MnSq = 1.65 and 0.38, respectively). Item difficulty calibrations of WHOQOL-BREF match person ability measures (i.e., HRQOL) fairly well. However, the person ability distribution showed obvious ceiling effects for EQ-5D. All items of EQ-5D were appeared to be less challenged in comparison with those of WHOQOL-BREF. Conclusion: Item-level analysis using the Rasch model supports the quality of culturally adapted items used to measure the HRQOL one exception; that is, whether or not to include misfit items as part of the HRQOL measurements. Additionally, cancer survivors undergoing palliative rehabilitation programs appear to have more of a tendency to view the EQ-5D items as being more challenging than the WHOQOL-BREF.

  • Real-time hybrid testing (RTHT) involves virtual splitting of the structure into two parts: physical substructure that contains the key region of interest which is tested in a laboratory and numerical substructure that contains the remaining part of the structure in the form of a numerical model. This paper numerically assesses four step-by-step integration methods (Central difference method (CDM), Operator splitting method (OSM), Rosenbrock based method (RBM) and CR-integration method (CR)) which are widely used in RTHT. The methods have been assessed in terms of stability and accuracy for various realistic damping ratios of the physical substructure. The stability is assessed in terms of the spectral radii of the amplification matrix while the accuracy in terms of numerical damping and period distortion. In order to evaluate the performance of the methods, five carefully chosen examples have been studied - undamped SDOF, damped SDOF, instantaneous softening, instantaneous hardening and hysteretic system. The performance of the methods is measured in terms of a non-dimensional error index for displacement and velocity. Based on the error indices, it is observed that OSM and RBM are robust and performs fairly well in all the cases. CDM performed well for undamped SDOF system. CR method can be used for the system showing softening behaviour. The error indices indicate that accuracy of OSM is more than other method in case of hysteretic system. The accuracy of the results obtained through time integration methods for different damping ratios of the physical substructure is addressed in the present study. In the presence of a number of integration methods, it is preferable to have criteria for the selection of the time integration scheme. As such criteria are not available presently, this paper attempts to fill this gap by numerically assessing the four commonly used step-by-step methods.

  • YoungChu NonYong(靈樞 論勇)seems to be named as such by its explanation in detail about the brave man who can and the coward who cannot stand pain respectively. In the first chapter, it is considered that the factors of diseases are dependent upon the state of skin and flash. In the second chapter, it is put about the problem of standing pain and not. In the third chapter, about the causes of resulting in brave or unbrave man. And in the fourth chapter, about drunken frenzy(酒悖). More concretely speaking, in the first chapter, it is explained that the factors of pathogenesis are related closely with the state of skin and flash, so to speak, though the outer factors which can arouse diseases should exist, the sensitivity of skin and flash which are the first defense tissue in human body, is more important factor. Undoubtedly, the environmental factors existing in physical nature which surrounds human life, have influenced upon human health, especially in ancient times. But, this chapter exhibits some reflections that ultimately the inner conditions of human body decide the attack of diseases. However, this chapter may have some corruptions for it reveals the contents which are not fit with the headline. In the second chapter, it is written that the sensitivity to pain is not only dependent upon the character of bravery but also upon the thickness of skin, the strength of flesh and the speed of response. In this we evidence that the ancient people had the idea that human pain-feeling is more dependent upon the degree of development of sensory neuron of physical body than one's character of bravery. In the third chapter, ti is described that the differences of physical development mainly influence the differences of the degree of mental bravery. In the fourth chapter, the drunken frenzy is explained. The implication is that as civilization has been growing, the drinking culture has made both in dividual and social health affair. The alcohol has the function of pleasing mind improving the quality of human life but it can also destroy both human body and mind when abused. About the harms like this, this part wams by the examples of drunken man's abnormal behaviors.

  • Purpose: This study investigated the effects of proprioceptive neuromuscular facilitation (PNF) exercise on the range of motion (ROM), pain, and functional activity of patients who received total knee arthroplasty (TKA). The purpose of this study was to provide fundamental data regarding the use of PNF exercise among patients with musculoskeletal disease. Methods: Fourteen patients who received TKA were randomly divided into an experimental group (n=7) that took part in PNF exercise and a control group (n=7) that performed general rehabilitation exercise. Both groups performed the respective exercises for 30 minutes, five times a week for 2 weeks. For the measurement of ROM, the range of knee flexion was measured using a clinometer smartphone application. A visual analogue scale (VAS) was used for the measurement of the level of pain. The timed up and go test (TUG) was conducted to measure functional activity. A paired t-test was performed to compare within-group changes before and after the PNF exercise. Differences between the experimental group and control group were analyzed by an independent t-test. For all tests, the level of statistical significance was set at ${\alpha}=0.05$. Results: After the exercise, there was a significant within-group change in VAS and TUG scores in the experimental group and control group (p<0.01). There was also a significant between-group difference in VAS and TUG scores after the intervention (p<0.05). Conclusion: General rehabilitation exercise is commonly applied as a treatment for TKA patients and is relatively effective. The application of PNF exercise may be useful in such patients, considering its effects on ROM improvement, pain reduction, and functional enhancement.

  • Push-up plus has been advocated for increasing the activity of the serratus anterior muscle, the most critical scapular stabilizer. However, no previous study has reported the possibility of compensatory motion on the part of the pectoralis major, which could substitute for the action of the serratus anterior during push-up plus. The aim of the current study was to investigate the immediate effect of electromyography (EMG) biofeedback of the pectoralis major muscle on the pectoralis major, upper trapezius, and serratus anterior muscles during push-up plus. Fourteen healthy young subjects voluntarily participated in this study; each subject performed push-up plus from the quadruped position, in two conditions (i.e., with or without visual and auditory biofeedback). Surface EMG was used to measure pectoralis major, serratus anterior, and upper trapezius activity. A paired t-test was used to determine any statistically significant difference between the two conditions. Additionally, effect size was calculated to quantify the magnitude of EMG biofeedback in each muscle. Visual and auditory feedback reduced pectoralis major muscle activity significantly (p=.000) and increased the serratus anterior muscle activity significantly (p=.002), but did not induce a significant difference in upper trapezius muscle activity (p=.881). Thus, it is concluded that the visual and auditory feedback of pectoralis major muscle activity can be used to facilitate serratus anterior muscle activity during push-up plus.

  • Background: Stroke recovery is a long and complex process. Successful stroke recovery seems to be strongly associated with patients' high motivation and committed participation. Patients' motivation is a key determinant of successful rehabilitation outcomes, but it is difficult in defining and measuring. Patients' participation is defined as the degree or extent to which subjects take part in rehabilitation activities and can be measured by observable behavior. Objects: The purpose of this study was to investigate the impact of patients' level of participation in rehabilitation on functional outcomes in patients with stroke. Methods: Forty post-stroke inpatients participated in this study. The level of rehabilitation participation was measured by the Hopkins Rehabilitation Engagement Rating Scale (HRERS). Other measures used for the evaluation were the Rivermead Mobility Index (RMI) and Korean version of the Modified Barthel Index (K-MBI). Overall measurements were made at early intervention and late intervention. Spearman correlation and multiple regression were used to measure the relationships between HRERS, RMI, and K-MBI. Results: The correlation found between HRERS total scores at early intervention and RMI total scores of late intervention was above moderate (r = 0.607, p < 0.01). RMI total scores at early intervention (p < 0.000), HRERS total scores at early intervention (p < 0.001), and disease duration (p < 0.003) were significant predictors of RMI total scores at late intervention. Conclusion: The level of participation at early intervention was associated with improvement in mobility. The level of mobility at early intervention, disease duration, and patients' participation at early intervention were important determinants of functional outcome. These findings suggest that patients' participation should be encouraged in order to achieve successful stroke recovery.

  • This paper investigates the physical properties of aramid and aramid/nylon hybrid air jet textured filaments for protective garments relative to ATY nozzle diameters. Three types of para-aramids(840d, 1,000d, 1,500d) and nylon(420d) filaments were prepared; in addition, 840d aramid/420d nylon and three kinds of aramid filaments were texturized with a variation of air jet nozzle diameters(0.6, 0.75, 1 and 1.2 mm) on the AIKI air jet texturing machine. The measured physical properties of 16 specimens are as follows. The linear densities of aramid and aramid/nylon hybrid ATY increased with a larger nozzle diameter. The tenacity and initial modulus of aramid and hybrid ATY linearly decreased with a larger nozzle diameter; in addition, the breaking strain increased with the nozzle diameter. The dry and wet thermal shrinkage of hybrid ATY increased with a larger nozzle diameter from 0.6 mm to 1 mm and then decreased at a nozzle diameter of 1.2 mm (which seems to be a critical diameter). The wet and dry thermal shrinkage of aramid/nylon hybrid ATY are influenced by the nylon part of the hybrid yarns because the wet and dry thermal shrinkages of aramid ATY are less than 0.2%. The instabilities of aramid and aramid/nylon hybrid ATY were not influenced by the air jet nozzle diameter; however, they increased with the linear density of ATY.
