Objectives: The purpose of this study was to investigate the effect of weight loss in Korean Medicine (KM) obesity treatment combined with self-monitoring and to identify the relevant factors which are related to successful weight loss. In addition to this, adverse events reported by the patients were analyzed to assess the safety of KM treatments for obesity Methods: This was a retrospective observational study that analyzed the medical records of the patients that participated in the 10-week of KM treatment. All patients took herbal medicine for weight loss and were instructed to reduce calorie intake and adhere to self-monitoring. Clinical data including body weight were collected for evaluating the effect of the treatments. Behavior factors affecting weight loss were collected. The correlation between each factor and weight loss was analyzed. Adverse events (AEs) were collected at each time to evaluate the safety of the intervention. Results: One hundred eighteen patients' records were included in this study. The average weight loss was 7.64kg(74.59kg to 66.95kg). 94.9% of patients lost 5% or more of their initial weight. The degree of weight loss was identified to be related to self-assessment of diet control and self-assessment of appetite control. The average self-weighing frequency significantly increased(2.45 times/week before treatment and 4.70 times/weeks during treatment). Constipation, insomnia, and dizziness were found to be the most frequent AEs, and except for one case, most AEs were mild cases. Conclusion: From this study, we found that KM obesity treatment combined with self-monitoring showed significant weight loss without serious AE.

Offshore wind power can be an alternative for onshore wind power which suffers from not only civil complaints regarding to landscape damage and noise but also wind power siting due to lack of onshore site candidates. Compared to onshore wind power, offshore wind power is free from these problems considering that generally the sites are far enough from the coast. And more electricity is generated in offshore wind turbines due to abundant offshore wind resources. However high installation costs of offshore turbines could deteriorate the economical efficiency. The main cause of the high installation costs comes from a long-term lease of the heavy marine equipment and the consequential high rental cost. In this paper, the conceptual design of the support structure for offshore wind turbines will be suggested for the installation of them with less heavy marine equipment.

Purpose: The objective of this study was to identify factors related to self-care adherence in symptomatic patients with heart failure (HF). Methods: Using a cross-sectional design, a convenience sample 209 outpatient clinic patients were recruited at two medical centers. Between October 2011 and August 2012, data were collected using the structured questionnaire. Factors related to self-care adherence were examined using hierarchical multiple regression. Results: Mean age of participants was 67.71 years and a half of them (53.6%) were female. They showed relatively low self-care adherence with mean scores of $61.88{\pm}12.92$. Lower self-care adherence was reported in asking for low sodium items, weighing oneself, checking for ankle edema, and exercising for 30 minutes. The overall model significantly explained 23.9% of variance in self-care adherence. Among the predictors, education, New York Heart Association functional classification, and social support were statistically significant in influencing self-care adherence. The variable of negative emotional status such as anxiety and depression were not found to be significant. Conclusion: These findings demonstrate that social support could help self-care adherence among symptomatic patients with HF. Thus, programs targeting self-care adherence in this population should consider the strategies improving social support.

Multiple waves of COVID-19 highlighted one crucial aspect of this pandemic worldwide that factors affecting the spread of COVID-19 infection are evolving based on various regional and local practices and events. The introduction of vaccines since early 2021 is expected to significantly control and reduce the cases. However, virus mutations and its new variant has challenged these expectations. Several countries, which contained the COVID-19 pandemic successfully in the first wave, failed to repeat the same in the second and third waves. This work focuses on COVID-19 pandemic control and management in Saudi Arabia. This work aims to predict new cases using deep learning using various important factors. The proposed method is called Deep Learning and Dynamic Weighing-based (DLDW) COVID-19 cases prediction method. Special consideration has been given to the evolving factors that are responsible for recent surges in the pandemic. For this purpose, two weights are assigned to data instance which are based on feature importance and dynamic weight-based time. Older data is given fewer weights and vice-versa. Feature selection identifies the factors affecting the rate of new cases evolved over the period. The DLDW method produced 80.39% prediction accuracy, 6.54%, 9.15%, and 7.19% higher than the three other classifiers, Deep learning (DL), Random Forest (RF), and Gradient Boosting Machine (GBM). Further in Saudi Arabia, our study implicitly concluded that lockdowns, vaccination, and self-aware restricted mobility of residents are effective tools in controlling and managing the COVID-19 pandemic.

Food waste is inevitable in any institutional food system. Although many factors contribute to plate waste, few quantitative studies of plate waste have actually been carried out. This study was undertaken to check (a) how the service style that affects the amount of plate waste, (b) the difference of plate waste between men and women and, (c) the influence of plate waste and customers'satisfaction to served meal. The survey was conducted through March 15 and April 9, 2000 by weighing the amount of plate waste and by questionnaires. Statistical data analysis was completed using the SPSS-PC program for descriptive analysis and ANOVA test. The results were as follows; (1) The largest amount, plate waste percentage measured were 19% of‘Hot alaska pollack soup’and 18% of‘Kuansh soup’respectively. (2) Amount of leftovers can be reduced if the pre-portioned serving style is changed to self-portioned serving. (3) The main reasons for leaving leftover were‘served too often’and‘disliked food’. (4) The customers'satisfaction rate was highly correlated with the leftover amounts.

This study was aimed to investigate the relations between self-selected intake of 3 macronutrie-nts and body weight gain and body fat accumulation in male rats given three isocaloric diets differing carbohydrate protein and fat contents concurrently. Also the effect of dietary restriction was observed. Forty two male rats of Sprague-Dawley strain weighing 68.7$\pm$6.1g were randomly divided into 2 groups and were allowed to have foods from 3 different cups for 8-hours a day or ad libitum, After 12 weeksthey were decapitated and their brains were quickly removed and frozen until they were assayed for serotonin and its metabolite 5-HIAA The carcass was dried at 105$\pm$2$^{\circ}C$ and measured the contents of body water and body fat. The animals chose a moderately high and constant carbohydrate level and showed the increase of percent protein intake with age and great individual variations. Protein in the diet seemed to trigger appetite and increase food intake which resulted in higher weight gains and in more fat deposition in the body. The concentration of brain serotonin did not show any correlations with the intake of nutrients. the accumulation of body fat and the gain of body weight.

Purpose: Dysmenorrhea is a menstrual condition characterized by severe and frequent cramps and pain. Effective treatment methods for dysmenorrhea are not yet fully understood. This research compares the effects of pain killers and heated red bean pillows. Methods: Data were got on demographic data, menstrual cycle status, and activities of daily living (ADLs) limitations, dysmenorrhea severity and menstrual pain scores. Following a 10% drop-out rate, 44 young women satisfied the inclusion criteria. To prevent any bias, the experimental and control groups were selected from different campuses. We used two sizes of red bean pillows: $13{\times}11.5cm$, weighing 400g; and $15{\times}18cm$, weighing 220g. For analysis, we used IBM SPSS statistics 19.0. Results: Ninety-nine point seven percentage of total subjects reported moderate to severe dysmenorrhea and 63.6% reported as moderate to severe daily activities limitations. The mean pain score with visual analogue scale was $80.2{\pm}9.42$ of 100 and 86.4% used pain killers to alleviate menstrual discomfort in all the subjects. In both groups, all three variables showed significant improvement and the Moos's Menstrual Distress Questionnaire (MDQ) scores changed significantly between menstrual and post-menstrual time point at within groups and not significantly different at premenstrual and menstrual time point at between groups. However, the MDQ score was significantly higher in experimental group than control group at post-menstruation time point and the degree of satisfaction was higher in the control group. Conclusion: This research shows that red-bean pillows on the abdomen are effective in assisting the ADL and diminishing pain severity. With regard to its safety the study indicates it can be a convenient and safe option for female students with menstrual discomfort in schoolas a non-pharmacological self-help.

Dental porcelain is one of the materials of choice for restoration where esthetics is of concern, but has a considerable potentials of wear. The wear of enamel is variable when opposed by different porcelain systems and surface conditions, and the exposed dentine and opaque porcelain due to clinical failure is expected to have high potentials of wear. The purpose of this study was to investigate the wear effects of self-glazed, polished incisal porcelain. polished dentine and opaque porcelain against human enamel in the laboratory by use of a pin-on-disk type wear tester. 4 types of dental porcelain($Vita-{\Omega}$, Ceramco-II, Vintage powder $Vita-{\alpha}$ of In-Ceram system) and type IV gold alloy as cotrol group were used for test specimens. Intact buccal cusps of maxillary premolar were used for enamel specimens, and the cusp converged to a point and was devoid of visible abrasion, caries, decalcification. The upper part was the cusp of a maxillary premolar and the lower part was a porcelain specimen. The enamel wear was deter-mined by weighing the cusp before and after each test. Surface profilometer was used to quantitate wear of the porcelain specimens. Vicker's hardness tester was used to evaluate the surface hardness of test specimens. The SEM was used to evaluate the wear surfaces. The results were as follows : 1 Self-glazed porcelain produced more enamel wear than polished porcelain, especially the enamel wear of $Vita-{\alpha}$ self-glazed porcelain was 3.2 times more than that of other groups. 2. Opaque porcelain produced least porcelain wear, $Vita-{\alpha}$ self-glazed porcelain produce greatest porcelain wear, but there was no statistically significant difference between the groups(p>0.05). 3. The enamel wear of dentine porcelain was 3.8 times more than that of polished inisal porcelain(p<0.05), and the enamel wear of opaque porcelain was 1.9 times more than that of polished inisal porcelain, but there was no statistically significant difference between the groups(p>0.05) 4. Overglazed porcelain produced less enamel wear than self-glazed porcelain, and more enamel wear than polished porcelain, but there was no statistically significant difference between the groups(P>0.05). 5. The hardness number of $Vita-{\Omega}$ dentine and Ceramco-II opaque porcelain was larger, but that of Vintage dentine and $Vita-{\alpha}$ self-glazed porcelain was similar to other groups. 6. Examination of SEM photographs revealed that overglazed porcelain had smoother surface than self-glazed porcelain, and self-glazed porcelain had smoother surface than polished porcelain. Much polishing scratches and larger porosities were observed on the opaque porcelain specimen, and much polishing scratchess and small porosities were observed on the dentine porcelain specimen.

Purpose of this study is to determine the reasonable portal approach for thoracoscopic right middle lung lobectomy in small sized dogs under 10 kg. Ten healthy beagle dogs weighing $8.67{\pm}0.49kg$ were included. Under general anesthesia, one-lung ventilation (1LV) was achieved using endobronchial blocker with guidance of fiber-optic bronchoscope. Two portal approaches were used; 8-6-10 intercostal space (ICS) and 8-6-5 ICS approach. Thoracoscopic right middle lung lobectomy was performed using endoscopic linear self-cutting stapler and specimen retrieval bag. Each approach was evaluated by scoring 0; bad, 1; endurable, 2; good, 3; excellent in following five category, 1) visualization, 2) triangulation; instrumental sword fighting in the thoracic cavity, 3) approach to hilar pedicle; application of stapler, 4) any obstacles in applicating Lap Bag, and 5) the operator's convenience. Favorable working space was secured by 1LV and thoracoscopic right middle lung lobectomy was successfully completed in all dogs. There was no need to change the portal location and iatrogenic complication. Most of scores were good to excellent in both approaches. Consequently, both approaches are feasible methods for thoracoscopic right middle lung lobectomy with one lung ventilation using endoscopic linear self-cutting stapler in dogs weighing less than 10 kg.
