Dietary nitrate supplementation from green leafy vegetables and beetroot is involved in the 'nitrate-nitrite-nitric oxide (NO) pathway' and is reported to have important vascular impacts. This study evaluated the blood parameters and blood flow change subsequent to a raw juice diet program. The 28 subjects who voluntarily participated in the raw juice diet program at Sahmyook University were instructed to drink the juice composed of fruits and vegetables instead of partaking the usual meal, at a scheduled time daily. The study was approved by the research ethics council of the Sahmyook University (SYUIRB 2014-043). Evaluation of the participants after the required duration revealed decreased levels of soft lean mass (P<0.05), skeletal muscle mass (P<0.001), body fat mass (P<0.001), body mass index (P<0.001) and circulating levels of total cholesterol (P<0.001), triglycerides (P<0.05), HDL-cholesterol (P<0.01), LDL-cholesterol (P<0.01), and blood urea nitrogen (P<0.001). Conversely, circulating levels of creatinine (P<0.001), hemoglobin (P<0.001), and hematocrit (P<0.01) were increased after the intervention. The blood flow levels were also increased after the program (P<0.001). Our results indicate that a short-term raw juice diet contributes to the improvement of vascular blood flow and blood lipid parameters, and decreases the lean muscle mass related to dehydration.

This study was a qualitative study using Colaizzi's phenomenological study method to understand the experience of reconstructing life through hemodialysis in chronic renal failure patients and to clarify the meaning of their vivid experience. The participants were eight chronic renal failure patients receiving hemodialysis. Data were collected through individual in - depth interviews with participants. The five categories that were found in the study were 'The beginning of unexpected difficulties', 'Burden of survival brought on by hemodialysis', 'The driving force of recovery', 'Choices and concentration of today in order', ' Every day life which must be woven sincerely'. The results of this study will help clinicians better understand the physical and mental suffering experienced by patients with chronic renal failure receiving hemodialysis and how they are constantly trying to adapt to a changed lifestyle. Also it might provide basic data for the development of efficient nursing intervention for the health management of hemodialysis patients.

This study aims to empirically structure the patterns of consumption and their effects on depression among the employed baby-boomers who were born in 1955 to in 1963. We used the 5th wave of Korea Retirement and Income Study(KReIS) in 2013 (n=2,585). The Latent Profile Analysis(LPA) estimated the empirical patterns of consumption and then a multiple regression analyzed the effect of consumption patterns on depression. The LPA results showed that the consumption patterns consist of four groups: Basic life-oriented class, Social life-oriented class, Home-based lifestyle class, and Advanced consumption-oriented class. The working baby boomers' depression was associated with their consumption patterns. Specifically, the social life-oriented class showed significantly lower depression than the basic life-oriented class and advanced consumption-oriented class. Other associates with higher levels of depression were found as lower education, having no spouse, lower self-rated health, higher levels of physical limitation, having a diagnosed disability, lower satisfaction with leisure activities, lower income, and lower subjective economic status in this study. Based on the results of this study, we propose the need for specialized financial intervention better for baby-boomers' retirement preparation in Korea.

Purpose - Identify the priorities of important factors through SWOT/AHP analysis method for vitalization of global marine sports in Korea. Through this, we will identify prerequisites and strategies for Korean marine sports to become a global powerhouse, including revitalizing the Korean Wave for Chinese consumers. It also revitalizes global competitiveness and draws policy implications. Research design and methodology - Through interviews with experts and literature data, elements of important opportunities, threats, strengths and weaknesses of marine sports are summarized. Based on this SWOT, the AHP technique is applied to determine which is first and what is important between the factors that save opportunities and increase strengths, and measures to cope with threats and factors that complement weaknesses. Through this, the priority factor of experts suggests a plan for activating strategic marine sports. Results - First, the current status of marine sports in Korea and the perception of consumers are grasped through current data and literature research. Sub-elements are derived based on the theoretical literature on SWOT elements and opinions of experts. Prioritization is identified based on the AHP questionnaire of Korean experts. Conclusions - The strategy was derived through SWOT/AHP analysis, and the following implications were obtained. Regionally, Busan is psychologically and geographically adjacent to China and Japan. It is also an area where human exchanges are actively taking place along with the volume of imports and exports. Due to the increase in China's marine sports industry and population, it is necessary to expand the scope of Korea to marine sports beyond cosmetics, dramas, movies, and Korean waves (Hallyu) stars.

As the global population becomes aging, the demand for health services for the elderly is expected to increase. In particular, The elderly visiting the emergency department sometimes have complex medical, social, and physical problems, such as having a variety of illnesses or complaints of unusual symptoms. The proposed system is designed to predict the mortality of the elderly patients who are over 65 years old and have admitted the emergency department. For mortality prediction, we compare the support vector machines and Feed Forward Neural Network (FFNN) trained with medical data such as age, sex, blood pressure, body temperature, etc. The results of the FFNN with a hidden layer are best in the mortality prediction, and F1 score and the AUC is 52.0%, 88.6% respectively. If we improve the performance of the proposed system by extracting better medical features, we will be able to provide better medical services through an effective and quick allocation of medical resources for the elderly patients visiting the emergency department.

Today, modern people perceive skin care as part of their physical health care, and acne is a common skin disease problem that is found on the face. In this paper, an effective acne detection algorithm using CIE $L^*a^*b^*$ color space has been proposed. It is red when the pixel value of the component image $a^*$ is a positive number, so it is suitable for detecting acne in skin image. First, the skin image based on the RGB color space is subjected to light compensation through color balancing, and converted into a CIE $L^*a^*b^*$ color space. The extracted component image $a^*$ was normalized, and then the skin and acne area were estimated with the threshold values. Experimental results show that the proposed method detects acne more effectively than the conventional method based on brightness information, and the proposed method is robust against the reflected light source.

The purpose of this study was to comparatively analyze the kinematic variables between the squash backhand and racquetball backhand strokes through three-dimensional cinematography. Three expert racquetball players and three expert squash players were involved in the data gathering process. The horizontal, vertical and lateral displacement of racket and trunk segment, intersegmental angular velocity of the wrist, elbow and shoulder joints, and the linear velocity of the racket were descriptively analyzed, and the followings were concluded. The racket of the squash backhand stroke showed an 'U' shaped movement where the racket moved rapidly downward and moved forward to make an impact and followed through to a front-top finish, while the racket of racquetball backhand stroke showed an 'O' shaped movement where the racket showed circular movement through the rear and bottom positions for the impact, and showed rotation through the lower-front and upper front to a upper-rear-ward finish during the follow-through. The peak velocity of racket was found before the impact point in the squash backhand stroke and at the impact point in the racquetball backhand stroke. For the final conclusion, for the squash backhand stoke, instructors might be better to make the racket move downward to make highest velocity before the impact and finished short follow-through, while for the racquetball backhand stroke, to make the racket move forward to make highest velocity at the impact and finished rather long follow-through.
