Investigating LVF directly, quantitatively and non-invasively by MUGA helps to validate and to follow up the effectiveness of new kinds of therapy. This is performed in controlled studies comparing groups of patients as demonstrated in the case of intracoronary thrombolysis. But it is also applicable on an individual basis. Contrary to the protocol in controlled studies medication was not discontinued in our patients before and after bypass surgery. This resembles the situation under routine conditions. Therefore the number of patients with reduced LVF was rather small before and after bypass operation. But, and this in the main result of our study, implementing MUGA for follow-up under this conditions can help: 1. To find out early those patients in whom LVF deteriorates postoperatively despite adequate medication. 2. To better define whether in cases of persistent or recurrent angina there is also deterioration of LVF. By this means MUGA can significantly contribute to find out whether reangiography is necessary or not, a question which often is difficult to answer in those patients.

English vowels are difficult to teach and learn because both teachers and learners cannot show or see shapes of vocal tract inside their own mouth cavities. The aim of this study is to examine what kind of changes occur in production and perception of English vowels by college students before and after lessons in order to provide fundamental materials for teaching students English vowels. Fifteen volunteer female students attending an English phonetics course participated in the lessons for one and half a month period. Formant values of vowels produced and perceived before and after the lessons were obtained using Flying Popcorn and Praat. Results showed that a produced vowel space after the lessons was greater than that before the lessons with no significant difference. Distances between some adjacent corner vowels were too close to be distinguished. Secondly, perceived vowels before and after the lessons were almost the same. Here again, some adjacent vowels were closely spaced. Thirdly, three groups which were divided by the length of the distance between the vowel /i-${\ae}$/ showed similar patterns in their perception and production. Generally the vowel space expanded from [u] to [${\ae}$]. The author concluded that there was no drastic improvement of vowel perception and production within a short period of time. Further studies would be desirable to examine how successful any long-term English vowel lessons would be and which methods should be taken to evaluate students' achievements proposed here.

Thomas L. Friedman's "Our New Historic Divide: B.C. and A.C. ― The World Before Corona and the World After" column is becoming the talk of the times. Whoever talks about the post-Corona world mentions "BC/AC" as a new concept. However, people seem to be overusing the term "BC/AC" while overlooking the specific context that Friedman emphasized. So, taking into account the cultural differences and contexts of the East and the West highlighted in Friedman's column, we devised the "BC/AC" ten-paradigm hypothesis. We hope these ten cultural shifts will be the first step in examining the post-Corona world.

The purpose of this study is to examine emerging trends in fashion films and the impact of COVID-19 through analysis of Prada films produced before and after the initial spread of the COVID-19 pandemic. We selected 40 cases occurring prior to the pandemic, from June to December 2019, and 21 cases occurring since the outbreak, from June to December 2020. To identify relevant trends, we conduct a literature review and examine a range of case studies. First, travel restrictions and confronting activities currently inhibit production. Through our case study analysis, we identify nineteen cases in between before and after COVID-19. Secondly, Prada can be seen to mainly produce episodes and promotional films. Additionally, it develops content showcasing brand values in environmental, cultural, creative, and sport-related fields; intended audiences extend beyond the realm of fashion. Thirdly, a new film category began to develop after the outbreak of COVID-19, namely, narrative films utilizing virtual interactions. According to our analysis results, we expect film production that is increasingly facilitated by virtual communication, technology utilization, and online platforms to continue even after the resolution of COVID-19. New film categories will emerge, and we predict that the gap between the number of cases before and after COVID-19 will narrow.

As electronic word of mouth plays an important role in purchase behavior among consumers, the number of studies on the impact of electronic word of mouth is rapidly increasing. Nevertheless, it is difficult to discover comparative studies on the mass media which had a great impact on consumer's purchase behavior before the impact of electronic word of mouth becomes greater versus the social media where electronic words of mouth are created and distributed. It is considered that it seems to be necessary to find an appropriate mutual supplement point between the media designed for a successful marketing by comparing and analyzing the existing mass media versus the social media, major media for electronic word of mouth. Therefore, this study aims to compare and analyze the impact of comments on movie revenue in the representative forms of mass media such as online news and social media blogs. In particular, this study also considers an appropriate media for promoting movies by period by comparing and analyzing the two media before and after film release. For analysis, this study collects the information on the number of comments on online news and blogs in 70 Korean movies released in 2011 and 2012 from five weeks before film release to eight weeks after film release on a daily basis via Naver. This study also collects the information on the movie revenue using the statistical data of movie industry from Korean Film Commission. As a result of empirical data analysis, it is found that the two media showed no difference in movie revenue before film release, but after film release, the impact of blogs was more significant than that of online news.

This study was conducted to evaluate the dry matter yield and quality of the before and after renovation of summer depression damaged pasture, and carried out at Chungnam National University ffom 1997 to 1999. The yield of DM in first and second year of after renovation, comparing with those of before renovation(6,547kg/ha), significantly increase obtained 12,291kglha and 13,50Ikg/ha, respectively(P<0.05). In the chemical composition, CP content and DM digestibility were markedly increased comparing with those of before renovation(P<0.05), but the contents of NDF, ADF, cellulose and lignin were decreased respectively(P<0.05). In the botanical composition, weeds after renovation was markedly decreased comparing with before renovation, but increased the percentage of herbage in summer depression damaged pasture. The results from this study, It is proved that a renovation method, which was conducted by two times of reseeding and raking, was effective in recovering botanical composition of herbage, and enhancing productivity and upgrading quality in summer depression damaged pasture.

Objective: The purpose of this study was to determine breast shape and ratio of breast enlargement women prior to development of breast enlargement patient's bra. Background: Although there are many previous studies on women's breast that did not undergo breast augmentation surgery, no studies have examined the breast type and proportion of women with breast augmentation. Method: In this study, we analyzed ratios and angles with photographs taken before and after breast augmentation on the frontal and lateral views of the breast, UPF and projection were analyzed too. We also compared the pre-operative and post-operative rates with those of previous breast studies, as well as the post-operative breast types for the desirable breast types. Results: The length and width of the breast base and the height of the breast projection increased after the operation. The rate of increase in width is larger than the vertical distance in the breast base, and the rate of increase in height of the projection is larger than the increase in the width. Specifically, in the vertical distance, the rate of increase in the lower portion is larger than that in the upper portion. In the width, the rate of increase on the inside is larger than that on the outside. Conclusion: The angles of the static relationship with the projection increased and the angles of the minor relation decreased. The changes in the size of the breast were visually observed in the overlapping of the triangle shape before and after the surgery. The changes were composed of the line connecting the angle and the measurement points. The pre-operative upper pole fullness (UPF) was mostly 0 and - 1, but after the surgery, +1, 0, -1, +2 were distributed, while post-operative levels of projection were distributed in the order of level 3> level 1> level 2. In comparison with the desirable breast type, it was found that the anatomical type was a more natural breast type than the round type of implant. Application: These results can be useful as basic data for the breast analysis of breast enlargement patients and their bra patterns.

Purpose: This study was intended to examine the effects of educating the Ventilator-Associated Pneumonia (VAP) control for the nurses working in the intensive care unit (ICU). Methods: The study was conducted using one group pre-post test research design. The education on infection control was provided to 31 nurses working at the medical and surgical ICUs. A comparison was then made in terms of the degree of performing infection control a month before, two weeks after, and three months after the education respectively. The incidences of VAP at the medical and surgical ICUs were compared for 3 months before and after the education. Results: The average performance scores between before and after the education showed statistically significant differences. Compared to three months before, the incidence of VAP after the education was decreased slightly from 5.48 to 1.88 per 1,000 ventilator days. Conclusion: It is necessary to continue the VAP education, specifically on infection prevention and control methods and the consistent evaluation of its effects as well as the development of standardized educational program should be approached extensively in further studies.

Objective: This study aimed to elucidate the effects of thoracolumbar fascia release (TLFR) on the degree of pain and disability in patients with shoulder pain. Design: Randomized control trial. Methods: Thirty subjects with shoulder pain participated in this study. They were allocated to TLFR group (n=15) and manual physical therapy (MPT) group (n=15). Shoulder pain and disability index (SPADI) and the score on the visual analogue scale (VAS) were measured before and after TLFR. Results: In the TLFR group, the degree of shoulder pain as indicated by SPADI measured after the intervention significantly differed from that before the intervention (p<0.05); moreover, in the MPT group, the degree of shoulder pain was significantly lower (p<0.05). The data of the 2 groups before the intervention significantly differed from those after the intervention (p<0.05). SPADI significantly differed within the groups (p<0.05), but not between the groups. The sum of SPADI did not differ significantly between the groups. The VAS scores of shoulder pain measured before the intervention significantly differed from those measured after the intervention (p<0.05) in the both groups. After the intervention, shoulder pain decreased significantly in the TLFR group as compared to that in the MPT group. Conclusions: TLF release was effective in reducing shoulder pain. The results of this study can be applied in clinical practice for TLFR performed to reduce shoulder pain. Further studies will need to be performed to elucidate the effects of TLFR on functional recovery.

Backgrounds and Objectives: Primary hyperhidrosis deeply affect a patient's quality of life, resulting in impairments of daily activities, social interactions and occupational activities. The objectives of the study were to assess quality of life(QOL) in patients with primary hyperhidrosis before and after treatment with oriental medicine. Methods : Between December 2006 and July 2007, 26 patients underwent oriental medicine treatment. which consisted of herb medicine. acupuncture and iontophosis (if palmar/plantar hyperhidrosis) treatment. QOL questionnaires comprised of dermatology life quality index (DLQI) and visual analogue scale (VAS) were employed before and after treatment Results : All 26 patients were evaluated. The treatment controlled primary hyperhidrosis in 84.6% of cases. The mean of DLQI score before treatment was 16.65 after treatment mean DLQI score was 8.18. The mean of VAS before treatment was 91.35 after treatment mean VAS was 49.92. QOL in patients with primary hyperhidrosis significantly improved after oriental medicine treatment. The improvements in QOL were similar in patientswith palmar/plantar, head, and systemic hyperhidrosis. Conclusions : Oriental medicine treatment leads to significantly improved QOL in patients with primary hyperhidrosis. Further studies are needed to evaluate the objective efficacy in patients with primary hyperhidrosis before and after oriental medicine treatment.
