The objective of this study was to investigate the correlations of marbling characteristics, including marbling score, intramuscular fat (IMF) content, and fleck traits, with meat quality traits and histochemical characteristics of the longissimus thoracis muscle from Hanwoo steers. Marbling fleck characteristics, especially area, number, and fineness (F) index, measured by computerized image analysis were strongly correlated with marbling score and IMF content (p<0.05). However, coarseness (C) index and F/C ratio were somewhat limited relationships with marbling score. In contrast, the IMF content and the number of smaller white flecks increased with increasing lightness value (p<0.05). Moreover, beef with higher marbling scores showed lower cooking loss and Warner-Bratzler shear force value compared to beef with lower marbling scores (p<0.05). Regarding the muscle bundle traits, as number of bundle increased, number of marbling flecks increased (p<0.05), although most marbling characteristics did not have significant correlation with muscle fiber or bundle characteristics.
Many recent studies have reported that the quality of input learning data was vital to the detection of regions of interest. However, due to a lack of research on the quality of learning data on lesion detetcting using gastroscopy, we aimed to quantify the impact of quality difference in endoscopic images to lesion detection models using Image Quality Assessment (IQA) algorithms. Through IQA methods such as BRISQUE (Blind/Referenceless Image Spatial Quality Evaluation), Laplacian Score, and PSNR (Peak Signal-To-Noise) algorithm on 430 sheets of high quality data (HQD) and 430 sheets of low quality data (PQD), we showed that there were significant differences between high and low quality images in lesion detecting through BRISQUE and Laplacian scores (p<0.05). The PSNR value showed 10.62±1.76 dB on average, illustrating the lower lesion detection performance of PQD than HQD. In addition, F1-Score of HQD showed higher detection performance at 77.42±3.36% while F1-Score of PQD showed 66.82±9.07%. Through this study, we hope to contribute to future gastroscopy lesion detection assistance systems that involve IQA algorithms by emphasizing the importance of using high quality data over lower quality data.

Introduction: The purpose of this study was to examine relationships among stroke patients' activities of daily living(ADL), depression, and quality of life(QOL). Methods: Data were collected by questionnaires from 251 stroke patients at 5 hospitals and 2 public health centers in Seoul and Kyonggi-Do. The following Questionnaires were utilized for this study: Functional independence measure(FIM) from Grange, Hamilton, and Sherwin(1986), the Korean CES-D scale from Randloff(1977), and quality of life scale from Bang, Hwal-Lan(1991). Results: Data were analyzed using the pearson correlation, t-test, and ANOVA with SPSS/WIN 12.0. The results of this study were as follow; The subjects consisted of 110 fern ales and 141 m ales. The mean score of activity of daily living was 87.2(range 18-126). Age, family history, comorbidity, paralysis site, and duration after diagnosis were significantly associated with activity of daily living. The mean score of depression was 23.8(range 11-44). Age, gender, education, and job were significantly associated with depression. The mean score of quality of life scale was 3.0(range 1-5). Gender, religion, education, job, economic status, and duration after diagnosis were significantly associated with quality of life. Relationships among activity daily living, depression, and quality of life scale: The activity of daily living had a negative relationship with depression score. The activity of daily living had a positive relationship with QOL score. The depression had a negative relationship with QOL score. Conclusion: Based on these results, it is necessary to run rehabilitation programs to improve stroke patients' ADL, depression. Also, it research for of identifying stroke patients' quality of life according to rehabilitation program.
Purpose: The purpose of this study was to find out the effect of hospice home care on the pain relief and quality of life of terminal cancer patients. Method: Experimental pre and post tests were provided to a single group to see the changes of quality of life of patients who were referred to a hospice home care department after having cancer treatment. They were visited at least 8 times for the duration of 4~6 weeks and were provided a 24 hour phone call service. 41 subjects were transferred to a hospice home care department after being discharged from hospital were selected. Result: 1)The first hypothesis that "the pain score of the subjects after receiving hospice home care would be different from before receiving hospice home care would be different from before receiving hospice home care" which scored 4.06 point at the first test and 3.41 at the second did not statistically show a significant difference(t=1.421 p=1.66), even though the pain score is decreased. 2)The 2nd hypotheses that "the quality of life score of the subjects after receiving hospice home care would be different from before receiving hospice home care" which scored 2.88 point at the first test and 3.39 at the second showed a significant difference(t=-6.759, p=.000) and was supported. Regarding the changes of quality of life score, social aspect(t=-5.745, p=.000), emotional aspect(t=-5.684, p=.000), and spiritual aspect(t=-6.889, p=.000) has significantly been increased, while physical aspect has been more decreased significantly than before the hospice home care is provided(t=4.282, p=.000). Conclusion: It was effective to provide hospice home care in relieving the terminal cancer patients' pain and in improving their quality of life, even though a short term hospice home care for 4-6 weeks was provided.
Purpose: The aim of this study was to evaluate chronological change of quality of life after surgery in patients with gastric cancer during one year postoperatively. Materials and Methods: Quality of life data were obtained from 272 gastric cancer patients who underwent curative gastrectomy between September 2008 and February 2011 at the Kyungpook National University Hospital. The Korean versions of the European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire Core (QLQ) 30 with gastric cancer-specific module, the EORTC QLQ-STO22 were used to assess quality of life. All patients had no evidence of recurrence or metastasis during the first postoperative year. Patients were asked to complete the questionnaire, by themselves preoperatively, 3-, 6-, 9-, and 12-months postoperatively. Results: Physical functioning score and role functioning score significantly decreased at first 3 months after surgery and the significant differences were noticed until 12 months after surgery. Emotional functioning score started with the lowest score before surgery and significant improvement was shown 6 months after surgery. Most symptom scores and STO-22 scores were highest at 3 months after surgery and gradually decreased, thereafter. Eating restriction, anxiety, taste, body image scores was highest at 3 months after surgery without significant decrease afterwards. Conclusions: Most scales worsened after surgery and gradually recovered afterwards with some differences in rate of recovery. However the scales did not fully recover by 1 year period. Further follow-up after 1 year would be helpful in determining which scales are permanently damaged and which are just taking longer time to recover.
Background: Among the factors reported to determine the quality of life of breast cancer patients are socio-demographic background, clinical stage, type of treatment received, and the duration since diagnosis. Objective: The objective of this study was to determine the quality of life (QOL) scores among breast cancer patients at a Malaysian public hospital. Materials and Methods: This cross-sectional study of breast cancer patients was conducted between March to June 2013. QOL scores were determined using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and its breast cancer supplementary measure (QLQ-BR23). Both the QLQ-C30 and QLQ-BR23 assess items from functional and symptom scales. The QLQ-C30 in addition also measures the Global Health Status (GHS). Systematic random sampling was used to recruit patients. Results: 223 breast cancer patients were recruited with a response rate of 92.1%. The mean age of the patients was 52.4 years (95% CI = 51.0, 53.7, SD=10.3). Majority of respondents are Malays (60.5%), followed by Chinese (19.3%), Indians (18.4%), and others (1.8%). More than 50% of respondents are at stage III and stage IV of malignancy. The mean Global Health Status was 65.7 (SD = 21.4). From the QLQ-C30, the mean score in the functioning scale was highest for 'cognitive functioning' (84.1, SD=18.0), while the mean score in the symptom scale was highest for 'financial difficulties' (40.1, SD=31.6). From the QLQ-BR23, the mean score for functioning scale was highest for 'body image' (80.0, SD=24.6) while the mean score in the symptom scale was highest for 'upset by hair loss' (36.2, SD=29.4). Two significant predictors for Global Health Status were age and employment. The predictors explained 10.6% of the variation of global health status ($R^2=0.106$). Conclusions: Age and employment were found to be significant predictors for Global Health Status (GHS). The Quality of Life among breast cancer patients reflected by the GHS improves as age and employment increases.

PURPOSE: To investigate the correlation between sleep quality, neck and shoulder pain, neck and shoulder disability, headache, and smartphone addiction in adults, as well as factors affecting sleep disorders in adults. METHODS: A total of 112 adults in their 20s were recruited for participation in this study. This study measured Pearson's correlation of sleep quality, neck and shoulder pain, neck and shoulder disability, headache and smartphone addiction. Logistic regression analysis (sleep disorder, without sleep disorder adults), was performed to analyze factors affecting sleep disorders. RESULTS: Sleep quality index was positively correlated with shoulder pain and disability index(SPADI)-pain score, SPADI-global score and smartphone addiction score. There was a significant difference in SPADI-pain score between the group with sleep disorders and the group without sleep disorders. Shoulder pain and disability were identified as factors affecting sleep disorders. The group with sleep disorders showed 1.088 times more shoulder pain than the group without sleep disorders, and the group with sleep disorders showed 1.006 times higher frequency of shoulder disorders than the group without sleep disorders. CONCLUSION: The results of the present study indicate that as sleep quality worsens, shoulder pain, disability, and smartphone addiction get worse. The group with sleep disorders had significantly increased shoulder pain compared to the group without sleep disorders. We also found that shoulder pain and disability were factors affecting sleep quality. Comparison between intervention method is warranted to better understand adults with sleep disorders.

The purposes of this study were to analyze the quality attributes and customer satisfaction in school foodservice by distribution place and to suggest an improvement plan. The survey was distributed to different respondents (students, parents, and faculty) at different types of schools (elementary school, middle school, and high school) on September 2008 in 16 cities and provinces. The statistics were analyzed using descriptive analysis, t-test, and ANOVA by SPSS 12.0. All foodservice quality attributes were significant different by school type and the students in elementary schools had higher scores than students in middle and high school. A comparison of scores by school type and distribution place demonstrated that elementary schools had a higher score for quality attributes and in middle and high school dining halls had a higher score for quality attributes. The overall customer satisfaction with school foodservice was higher for dining halls than classrooms for all respondents (students, parents, and faculty). For students, the overall customer satisfaction score was 69.1 for schools using dining halls and 66.4 for schools using classrooms. The overall customer satisfaction for classrooms was higher in elementary school but, this score for middle and high school was higher for dining halls. Therefore, students prefer dining halls to classrooms. Especially, as the students grow, they have an increased preference for dining halls.
