The purpose of this study was to examine the relationships between the nutrient intake and level of depressive symptoms. A total of 5,761 subjects with depression were selected for the main data analysis from a Korean National Health and Nutrition Examination Survey, KNHANES (2016), and were divided into low depressed and high depressed groups. The data were analyzed by descriptive analysis, ${\chi}^2-test$, logistic regression, and t-test using SPSS 24.0 statistics. The results revealed significant differences in the prevalence of depression according to sex (P<0.001), age (P<0.001), income (P<0.001), and education (P<0.001). Regarding the health behavior, higher stress levels (P<0.001) and smoking habit (P<0.001) appeared to be strongly associated with high levels of depression. On the other hand, the possibility of experiencing depressive symptoms was lower when the number of walking days per week was more than 3 days (P<0.05), when the number of working days per week was more than 5 days (P<0.01), and the rate of aerobic physical activity was higher. Based on the 'Dietary Reference Intakes for Koreans 2015', the subjects in the low depression group showed better intake of energy and 22 nutrients than the high depression group.

The purpose of this case study was to introduce functional electrical stimulation(FES) for paraplegic patients. FES provides the ability to rise from sitting to standing, maintenance of a standing position, and the ability to walk with a reciprocal gait. Six channels of electrical stimulation are sufficient for synthesis of a simple reciprocal gait pattern in these patients. During the double-stance phase, knee extensor muscles of both knees are stimulated, providing sufficient support for the body. Only one knee extensor muscle group is excited during the single-stance phase. The swing phase of the contralateral lower extremity is accomplished by eliciting the synergic flexor muscle response through electrical stimulation of afferent nerves. The transition from the double-stance phase to the swing phase is controlled by two hand switches used by the therapist or built into the handles of the walking frame for using by the patient. A twenty-five years old male was with a T9/T9 spinal cord injury due to a traffic accident and admitted to Yonsei Rehabilitation Hospital for comprehensive treatment. After 30 days of training using the Parastep(R) he was able to stand for 10 minutes. After 43 days, he was able to walk and at discharged he could walk for 100 meters.

Detecting human in images is a challenging task owing to their variable appearance and the wide range of poses the they can adopt. The first need is a robust feature set that allows the human form to be discriminated cleanly, even in cluttered background under difficult illumination. A large number of vision application rely on matching keypoints across images. These days, the deployment of vision algorithms on smart phones and embedded device with low memory and computation complexity has even upped the ante: the goal is to make descriptors faster compute, more compact while remaining robust scale, rotation and noise. In this paper we focus on improving the speed of pedestrian(walking person) detection using Histogram of Oriented Gradient(HOG) descriptors provide excellent performance and tracking using kalman filter.

A 4 years old male mixed breed dog, which weighed 25.5 kg, referred to Veterinary Teaching Hospital at College of Veterinary Medicine in Chonnam National University, because of chronic hindleg lameness. Click sound by flexion and extension of stifle joint, positive reaction by cranial drawer movement, fat pad sign and tibial position in cranial drawer position on the lateral radiographic view, medial patellar luxation (grade II), and lameness score 2.5 at standing and 2 at walking in right hindleg were showed. Under general anesthesia with enflurane, after medial arthrotomy, it was performed to remove remnants of cranial cruciate ligament and torn medial menisci and joint closed. In modified retinacular imbrication technique, one lateral fabellar/tuberosity suture, one medial fabellar/tuberosity suture, and one imbrication suture adjacent to the patella were placed. At 9 days after operation, lameness score 0 was observed and general condition was excellent.

Purpose: The purpose of this study was to investigate the factors affecting energy drinks consumption among adolescents in South Korea. Methods: The study is a secondary analysis. Using statistics from the 11th (2015) Korea Youth Risk Behavior Web-based Survey, any variations among the subjects were presented as percentages and analyzed by $x^2$ test and logistic regression analysis. The study sample comprised 68,043 middle and high school students in South Korea. Results: In Model 1 including general characteristics, the significant factors of energy drinks consumption were gender, weekly allowance, cohabitation with family. and economic status. In the final model where health-related characteristics were added, the significant factors were gender, school type, weekly allowance, cohabitation with family, stress level, sadness, drinking, smoking and walking days. Conclusion: The result suggests that intensified education on energy drinks consumption is needed not only at schools, but in the whole community. Also, adolescents' awareness of potential health effects of energy drinks, in particular when mixed in alcoholic beverages, should be increased through health education.

Purpose: To examine the effects of the aerobic exercise program on changing the body composition, blood lipids and self-esteem of the obese elderly women. Method: A total of 26 obese elderly women(%body fat: over 30%) have been selected for this research[Experimental Group(EG):13, Control Group(CG):13). Walking at a 50% intensity was administered 4 days a week for 14 weeks. The data was analyzed using the SPSS program. Result: The level of % body fat, TC, LDL-C, and %TC/HDL-C in EG was significantly lower than those of the CG after 14 weeks. In addition, the level of HDL-C and self-esteem in EG was significantly higher than those of the CG after 14 weeks. However, TG, body weight between groups didn't appear significant at the end of 14 weeks. Conclusion: The results showed that the aerobic exercise program was effective in changing body composition, blood lipids and self-esteem of the obese elderly women.

From July 1988 to January 1991 six patients, aged 29 to 70 years underwent transfemoral thrombectomy for the treatment of deep vein thrombosis. Preoperative venograms showed thrombi in the following locations: calf veins[five], superficial femoral or popliteal veins [four], common femoral veins[three], and iliac veins[three], Durations of symptoms before admission were from 1 day to 20days. Operations were performed under local anesthesia and all the patients were requested for doing Valsalva maneuver during thrombectomies. All patients were received heparin pre-and postoperatively, which was switched to Coumadin for preventing of rethrombosis. One patient was transferred to other hospital 4 months after operation due to regional reason, and the remained five patients were evaluated with a mean follow-up time of 20 months. There was no evidence of postoperative pulmonary embolism. Three of five patients were clinically asymptomatic. One complained of the heaviness of involved leg in the evening, and the other had discomfort on walking Even though our cases were a few in number, we concluded that thrombectomy is a valuable treatment modality of deep vein thrombosis.

Pilots' fatigue is one of the most serious threat to flying safety. Fatigue is influenced by many factors like sleep deprivation, daily activities, aging, stress, etc. This study was designed to investigate military pilots' daily activities. 20 pilots' daily activity was monitored by activity monitor, Fitbit(R), and the survey about sleep time and flight time was conducted. They placed Fitbit(R) on their waist for 5 days. During flight, they removed Fitbit(R) that had been used for checking their steps and walking distances. It was found that the average sleep time is 6.7 hours for fighter pilots. It was a little shorter than average sleep time for adults, 8 hours. Average steps per day was 6,838 which is more than sedentary worker's but less than active worker's. Their daily activities were not as high as we had expected. But their sleep time was very short. Flight surgeons should recommend them to take a rest and get sleep during rest period.
