Purpose: The purpose of this study was to review systematically the effects of home based pulmonary rehabilitation in chronic obstructive pulmonary disease (COPD) patients using qualitative synthesis. Methods: Studies designed randomized controlled trials were identified to extract data and to assess the quality of studies in 8 domestic and 3 foreign search engines, and hand search reference reviews. Results: A total of 9 studies met the inclusion criteria. Overall, the methodological quality of the studies ranged from average to poor. Home based pulmonary rehabilitation consisted of exercise, education, and psychosocial interventions. Several exercises such as aerobic, strength, respiratory muscle training, and flexibility were used in home based pulmonary rehabilitation for COPD patients. Upper muscle exercise and walking were the most frequently used exercises. The most common topics for education were 'knowledge of the illness' and 'drug management'. Walking distance test (WDT) and quality of life (QoL) were the most frequently measured as the dependent variables to evaluate rehabilitation outcomes, followed by pulmonary function test (PFT) and dyspnea. WDT was the most effective outcome, followed by dyspnea, QoL and PFT. Conclusion: This study informed about the details of scientific and effective home based rehabilitation programs in COPD patients for future researchers and clinicians. These findings can help expand the recognition and accessibility of home based rehabilitation in COPD patients.

Purpose: The purpose of this study was to examine the correlation between a flexible parental visiting environment and parental stress in neonatal intensive care units (NICUs). Methods: The study participants included 60 parents of premature infants in NICUs. Structured questionnaires and interviews, as well as observations by researchers using a caregiving behavior checklist, were used to measure the flexibility of the parental visiting environment and parents' stress levels. Quantitative and qualitative data were collected concurrently and were initially analyzed as separate data sets. Data collection extended from March 11, 2018 to June 30. 2018 and the data were analyzed using descriptive statistics, the independent t-test, one-way analysis of variance, and Pearson correlation coefficients. Results: There was a negative correlation (r=-.30, p=.021) between parental stress and the total number of visits in 7 days. We also found that the average duration of each visit and the number of caregiving behaviors performed by parents were positively correlated (r=.73, p<.001). Conclusion: When designing a flexible visiting environment for parents, parents should be encouraged to visit their babies. By doing so, stress can be reduced both for babies and for parents. Therefore, it is suggested that the related polices and regulations in South Korea should be changed to provide more a flexible visiting environment to promote better parent-child attachment and family adjustment.

The quality of the E-learning education in Saudi Arabia has been a major concern by many academicians, especially, and people in general as this platform has not been a priority for education. Not until recently, the world has been impacted by the Covid-19 pandemic, which makes every education institution shifted to the online platform to continue the education for the students. Thus, many studies on the perceptions on the online learning have been carried out, and though many are focusing on the perceptions by the education institutions' faculty and administration, there is a lack in the amount of study performed to analyse the students' perceptions of online learning during the pandemic time. The current study is conducted by utilising qualitative methods in order to collect information and investigate the students' perception regarding online learning during the pandemic Covid-19, based on their individual experiences. A number of fifteen (15) students were selected as respondents for the study, in which structured interviews were conducted by using a convenient sampling technique for data collection. Through the discussion, all of the positive and negative perceptions of online learning, as well as the factors contributing to those perceptions were identified. The results of the study found that the positive perceptions were contributed based on the flexibility, cost-effectiveness, availability of the electronic research databases, and well-designed online classroom interfaces. For the negative perceptions from using online learning platforms, the respondents informed that they were contributed by the lecturer's delayed feedback, lack of technical support by lecturers, low in self-esteem and self-motivation, feel isolated, one-way of educational methods, and poorly-designed class materials. Through the findings, the school's administration and lecturers would be able to know the struggles experienced by the students, and eventually come out with better solutions to improve their teaching methods.

The industry of modern clothing has deviated from the overflow of commercialism and the standardization and nowadays is going toward pursuing art, creativity, and high added value. This trend brings the return of the natural materials from the synthetic textiles and increases the value of old and handmade fabrics. Finally, the handmade-paper, which is a natural material, comes to be reconsidered as a new material for the clothing. Therefore, as the natural materials and the manufacture of handmade clothing are rising again, the qualitative improvement and globalization of clothing industry should be first realized through the developments of creative and various clothing materials and new expressing techniques. The above investigation and study have been synthesized and analyzed as follows: First, through the study on the origin of the paper clothing, its historical background and the process of its development, we've learned these two facts following : the paper clothing of the East in the past mostly had practiced meanings. On the other hand, in the West it had meanings which were raised the artist's emotions and beauty-consciousness to the artistic level by the various kinds of expressing methods. Second, handmade-paper was manufactured by the embedding method, which mixed mulberry pulp, gauze, corn, hair, sisal, silk and so on. It was found that handmade-paper had the affluent and proper texture as the clothing material and was be able to control the clarity through the variation of thickness. It was also confirmed that the creative and original texture with hand-worked molding beauty was obtained by the use of handmade-paper. Third, when the handmade-paper is used, the molding beauty of plane, relievo, and solid can be freely pursued, and various and effective molding conformation can be constructed by the effect of superposition and repetition. Also, because the maximum discretion from the various optional manufacturing methods is allowed, the molding beauty can be maximized when the clothes are manufactured with handmade-paper. Fourth, the gauze with strong drape was combined to overcome the stiffness and the tearing of the paper. As a result, the durability and the wearability of the paper were strengthened and thus the thus the applications as the clothing material were enlarged. In conclusion, in order to enhance the value, creativity, practicality, and artistic sense of the design for modern clothing, the clothes made of handmade-paper should be more studied. Moreover, for the generalization of paper clothes, the studies on the development of practical paper with paper with water resistance, post-treatment after dyeing, flexibility, and durability should be done. I really hope that this study will be the motive to provoke the possibility of handmade-paper as new clothing material in not only practical sense but also artistic sense.

Purpose: The scan time reduction helps to yield more accurate results and induce the minimization of patient's motion. Also we can expect that satisfaction of examination will increase. Nowdays medical equipment companies have developed various programs to reduce scan time. We used Onco. Flash (Pixon method, SIEMENS) that is an image processing technique gated cardiac blood pool scan and going to evaluate its clinical usefullness. Materials and Method: We analyzed the 50 patients who were examined by gated blood pool scan in nuclear medicine department of Asan Mediacal Center from June $20^{th}$ 2008 to August $14^{th}$ 2008. We acquired the Full-time (6000 Kcounts) and Half-time (3000 Kcounts) LAO image in same position. And we acquired LVEF values ten times from Full-time, Half-time images acquired by the image processing technique and analyzed its mean and standard deviation values. To estimate LVEF in same conditions, we set automatic location of the LV ROI and background ROI based on same X and Y-axis. Also we performed blinding tests to physician. Results: After making a quantitative analysis of the 50 patients EF values, each mean${\pm}$standard deviation is shown at Full-time image $68.12{\pm}7.84%$, Half- time (acquired by imaging processing technique) $68.49{\pm}8.73%$. In the 95% confidence limit, there was no statistically significant difference (p>0.05). After blinding test with a physician for making a qualitative analysis, there was no difference between Full-time image and Half-time image acquired by the image processing technique for observing LV myocardial wall motion. Conclusion: Gated cardiac blood pool scan has been reported its relatively exact EF measured results than ultrasound or CT. But gated cardiac blood pool scan takes relatively longer time than other exams and now it needs to improve time competitive power. If we adapt Half-time technique to gated cardiac blood pool scintigraphy based on this study, we expect to reduce possible artifacts and improve accessibility as well as flexibility to exam. Also we expect patient's satisfaction.
