The present study was undertaken to analyze the effects of different types of treatment on excess post exercise oxygen consumption (EPOC), flexibility, free radical and antioxidants in women using a horseback riding therapeutic device. Subjects were trained in regular horseback riding exercises for 12 weeks (3 times/wk). The effects of this exercise were examined by means of a single session of horseback riding that lasted for 30 min. 21 women were recruited from a public health center and divided into 3 groups (passive recovery group, passive+massage recovery group, and dynamic recovery group). 3 types of recovery patterns were determined after a single trial of horseback riding exercise. Their flexibility were determined pre-and post-training by Paired T test, and ANOVA were used to analyze the data. The results were as follows: Among the 3 groups, the dynamic recovery group showed the highest levels of EPOC compared to the other groups, and also showed higher levels of anti-oxidants, as did the passive+massage recovery group compared to the passive recovery group. Moreover, horseback riding exercise greatly increased flexibility in the women. In conclusion, regular horseback riding training is recommended to enhance the flexibility of women and dynamic recovery is recommended to enhance EPOC and anti-oxidants after a single bout of exercise. Further study is needed in this area.

The purpose of this study was to investigate the relationship between obesity indices, nutritional knowledge, nutritional intake status, and some blood parameters in obese middle-school students. Anthropometric measurement, 24-hour recall for dietary intake, blood analysis and Questionnaire response including nutritional knowledge, nutritional attitude, and self-satisfaction were conducted in 42 obese middle-school students (28 male and 14 female) participated in the nutritional camp program carried by Bucheon district public health center in Kyunggi-do. The mean age of subjects was 13.9 years. The average body weight, BMI, obesity index, WHR and percent body fat were 75.5 kg, 29.1 kg/$m^2$, 30.1, 0.89 and 33.3% in male subjects, and 67.8 kg, 27.5 kg/$m^2$, 25.3, 0.81 and 34.6% in female subjects. The average nutritional attitude, the self-satisfaction and the nutritional knowledge scores were no significant difference between male and female subjects. Average intake of energy were 85.5% of RDA in males and 98.1% of RDA in females. The percentage of energy from fat was higher in both male (29%) and female (26%) subjects than recommended level. Calcium, iron, zinc, vitamin A, vitamin B$_2$, vitamin C, niacin and folate intakes were below the RDA for them. In the results of correlation analysis, body weight, BMI and obesity index were positively correlated with systolic blood pressure and cholesterol intake. There was a negative correlation between percent body fat and nutritional knowledge. Body weight was negatively related to HDL-cholesterol, whereas it has positive relation with RBC, hemoglobin and hematocrit. BMI and obesity index were negatively related to HDL-cholesterol, but positively related to RBC, respectively. WHR showed positive relationship with serum GPT, glucose and MCV.

To investigate the characteristics of edible flowers as a food material, we have examined the kinds, colors, sizes, fresh weights, pigments and shipping periods of edible flowers marketed on the cropping farms, selling agencies and Internet shopping malls from February through September, 2005. Thirty six kinds of edible flowers were marketed in Korea, and all but the chrysanthemum were introduced species. The characteristics of edible flowers were shown differently by the varieties following the same kinds of flowers. Those colors were yellow (twenty five kinds), red (twenty three), pink (twenty), white (eighteen), and orange (sixteen). Flower diameters were measured and showed that seven kinds of edible flowers were 1.0 to 2.0cm, fourteen 2.0 to 3.0cm, sixteen 3.0 to 4.0cm, eight 4.0 to 5.0cm, and nine over 5.0cm. Flower fresh weights were measured as follows: twenty one kinds of edible flowers were under 0.5g ($58.3\%$), eight were $0.6\∼1.0g(22.2\%$), and six were $1.1{\∼}1.5g(16.7\%$). The taste of edible flowers was often bitter (twenty one kinds), sweet and sour (seven), somewhat fragrant (six), fishy (three), and others (nine). The pigments of edible flowers were anthoxanthin (twenty seven kinds), flavonoid (twenty three), carotenoid (seventeen), and betanidin (four).

Background : Nowadays drug resistant tuberculosis is making problems in the treatment of pulmonary tuberculosis and its number is increasing. Several reasons for this are considered including irregular medication, poor drug compliance and wrong regimens. But there are treatment failure cases in spite of regular medication with short-term standard regimens. We reviewed clinical data of 50 patients to find out possible causes of this. Method : Subject of this study was 50 patients who failed in the primary treatment of pulmonary tuberculosis in spite of regular medication with short-term standard regimens. All of them were under treatment with secondary regimens in National Masan Tuberculosis Hospital on Oct 1996. The patient's records were analyzed retrospectively and direct interviews with patients were done. Results : There were relatively more patients in the age of 20th. Male overwhelmed in number. There were smoking in 22 patients and drinking in 24 patients during medication. 17(34%) patients had family history of tuberculosis. Public health center was the most common site for the initial diagnosis among medical institutes. 42 patients had subjective symptoms for pulmonary tuberculosis. 38 patients got sufficient explanation from medical institute about tuberculosis and medication courses. 24 patients had bilateral lesions on chest X-ray film and 43 patients had cavitary lesions. 29 patients had past history for pulmonary tuberculosis with regular medication. The results of drug sensitivity test showed resistance in 41 patients of whom we could get the results. Conclusion : Main cause of treatment failure of pulmonary tuberculosis in spite of regular medication with short-term standard regimens was drug resistance. Several factors were considered to be related to high prevalence of drug resistance, including age of 20th, male, family history for tuberculosis, bilateral lesions or remaining cavitary lesion on chest X-ray film.

To investigate the beneficial effects of an agar gel mask (AGM) on UV-induced photoaging, SKH-1 hairless mice were treated with a topical application of AGM and an AGM dipped in essence (AGMdE). The mice were divided into an no radiation group, UV + AGM, UV + AGMdE, and UV + vehicle (PBS) treatment groups. Alterations in skin wrinkles, skin phenotype, histological structures, oxidative status, and toxicity were then evaluated during 4 weeks of exposure. The topical application of AGM and AGMdE inhibited wrinkle formation, suppressed the erythema index, prevented transepidermal water loss, and enhanced skin hydration. In addition, epidermal thickness recovered to a similar level as that in the no irradiation group in the UV + AGM and UV + AGMdE treatment groups compared with the UV + vehicle (distilled water) group. Furthermore, the expression levels of matrix metalloproteinase-1 (MMP-1) and tyrosinase were reduced in the UV + AGM and UV + AGMdE treatment groups, although the highest level varied. Moreover, superoxide dismutase (SOD) activity was significantly lower in the UV + AGM and UV + AGMdE treatment groups as compared with the UV + vehicle group. No significant alterations induced by most toxic compounds were measured in serum biochemical markers and liver and kidney histological features of the UV + AGM and UV + AGMdE treatment groups. These results suggest that AGM may protect against skin aging by regulating skin morphology, histopathological structures, and oxidative conditions.

Purpose: We examined aqueous humor levels of 25-hydroxyvitamin D (vitamin D) in patients with age-related macular degeneration to investigate possible relationships between aqueous humor vitamin D levels and clinical manifestations. Methods: Patients > 50 years of age, 52 eyes of 34 patients with age-related macular degeneration, and 23 eyes of 17 patients treated with cataract surgery without retinal disease, were examined for aqueous humor vitamin D levels and compared. The experimental group was divided into two groups according to the median value of aqueous humor vitamin D levels. We compared the clinical manifestations of macular degeneration in both groups and identified relationships between aqueous humor vitamin D levels and clinical features. Results: Vitamin D levels in the aqueous humor were significantly lower in the experimental group than in the control group (experimental, $10.03{\pm}10.1ng/mL$ vs. control group, $40.8{\pm}16.4ng/mL$; p < 0.001). Patients with high vitamin D levels in the macular degeneration group had a higher percentage of fibrovascular pigment epithelial detachments than those in the low grade group (high grade group, 65% vs. low grade group, 27%; p = 0.003). Multiple linear regression analysis showed a significant correlation between vitamin D levels and the total number of anti-vascular endothelial growth factor intravitreal injections within 6 months (standardize coefficient, ${\beta}=-0.336$). Conclusions: Patients with wet age-related macular degeneration had significantly lower vitamin D levels in the aqueous humor compared to control group subjects of similar ages. However, in patients with macular degeneration, low vitamin D levels were associated with a greater number of intravitreal injections, while higher levels of vitamin D may lead to more advanced forms of fibrovascular retinal pigment epithelium and related low vision. These relationships were not always constant, so further studies on the relationships between local vitamin D levels and ocular disorders are needed.

Objectives : The purpose of this study was to investigate the needs for return-to-work support of cancer survivors and related factors in patients with cancer and their caregivers. Methods : 182 patients and 114 caregivers were recruited. Distress Thermometer and Problem List and scale ranging 0~10 measuring the degree of needs for return-to-work support were utilized. The needs for return-to-work support between the patient group and caregiver group (patient's needs evaluated by the caregiver) were compared, and related factors were investigated using logistic regression analysis. Results : 34.6% and 28.1% of patients and caregivers reported return-to-work support of cancer survivors is "very necessary". The degree of needs was 6.60±3.365 points in the patient group and 6.17±3.454 points in the caregiver group, with no significant difference (p=0.282). The needs for return-to-work support evaluated by patients was high when they underwent surgery (OR=2.592, p=0.007), has fertility problems (OR=6.137, p=0.025), has appearance problems (OR=2.081, p=0.041), or has fatigue (OR=2.330, p=0.020). The needs for return-to-work support of patients evaluated by caregivers was high when patients treated with breast cancer (vs respiratory cancer, OR=13.038, p=0.022 ; vs leukemia/lymphoma, OR=4.517, p=0.025 ; vs other cancer, OR=13.102, p=0.019), has work/school problems (OR=4.578, p=0.005), or has depression (OR=3.213, p=0.022). Conclusions : The degree of needs for return-to-work support of cancer survivors was high, and factors related to the needs were different between the two groups. This suggests that return-to-work support of cancer survivors is required, and clinical characteristics, the distress of patients, and differences between patients and their caregivers should be considered in establishing a support plan.

Purpose: To date, studies of firearm and explosive injuries in the Korean military have been limited compared to its importance. To overcome this, this study examined the characteristics of musculoskeletal damages in soldiers who have suffered firearm and explosive injuries over the past four years. Materials and Methods: From January 2015 to July 2019, military forces who had suffered musculoskeletal injuries from firearms or explosive substances were included. The medical records and radiographs were reviewed retrospectively, and telephone surveys about Short Musculoskeletal Functional Assessment (SMFA) for this group were conducted. To compare the functional outcomes, statistical analysis was performed using a t-test for the types of weapons, and ANOVA for others. Results: Of the 61 patients treated for firearms and explosives injuries, 30 patients (49.2%) were included after undergoing orthopedic treatment due to musculoskeletal injury. The average age at injury was 26.4 years old (21-52 years old). The number of officers and soldiers was similar. Eleven were injured by gunshot and 19 by an explosive device. Sixteen were treated in the Armed Forces Capital Hospital and 10 at private hospitals. More than half of the 16 patients (53.3%) with a fracture had multiple fractures. The most common injury site was the hand (33.3%), followed by the lower leg (30.0%). There were 14 patients (46.7%) with Gustilo-Anderson classification 3B or higher who required a soft tissue reconstruction. Fifteen patients agreed to join the SMFA survey for the functional outcomes. Between officers and soldiers, officers had better scores in the Bother Index compared to soldiers (p=0.0045). Patients treated in the Armed Forces Capital Hospital had better scores in both the Dysfunction and Bother Index compared to private hospitals (p=0.0008, p=0.0149). Conclusion: This is the first study to analyze of weapons injuries in the Korean military. As a result of the study, the orthopedic burden was high in the treating patients with military weapon injuries. In addition, it is necessary to build a military trauma registry, including firearm and explosive injuries, for trauma treatment evaluation and development of military trauma system.

This study is a basic research to suggest user-centered general hospital environmental design guidelines, which aims to analyze user's behavior characteristics across generation in general hospital. For this purpose, this study constructed an analysis tool through the literature review with regard to generation and behavior characteristics in general hospital. Besides, an online survey regarding user's behavior in general hospital was conducted targeting from 20s to 60s, 300 persons for each group, total 1,500 persons for about 3 weeks since September 1, 2016. The results of this study are as follows: (1) Based on the generation, there were significant differences in relevant categories of their visiting frequency, visiting purpose, visiting hour, transportation, companion, behavior during the wait and selection of a general hospital. (2) In all generation, they responded that they have visited once or twice per year. People in 20s and 30s responded that their visit for the hospital is to receive specific treatment, while other people in 40s, 50s and 60s visit the hospital majorly for routine check-ups. Therefore, it is imperative for a health check-up center to design an environmental plan that reflects the characteristics of elders in 40s, 50s and 60s. (3) People in 40s, 50s and 60s usually visit a general hospital in the mornings of weekdays, while generations in 20s and 30s responded that they mostly visit the hospital in the mornings of weekend. (4) When they visit a general hospital, people in their 20s are usually using public transportations, while people in their 30s to 60s are using their own vehicle. (5) People in their 20s majorly visited 'lobby'. In older generations, they tend to visit 'outpatient clinic'. Therefore, it is necessary to build an outpatient clinic environment that considers the elderly. (6) Patients majorly responded that they are using their cell phone, while waiting for their clinic call. In elder generations, they responded that they are more likely watching TVs, reading books/magazines or doing nothing. Therefore, it is essential to provide cell-phone related services and environmental supports. Visually attractive media can be utilized for this purpose.

Urinary cadmium is used as a sensitive indicator for internal Cd dose, and increased excretion of $N-acetyl-\beta-D-glucosaminidase(NAG)$, $\beta_2-microglobulin(MG)$ and total protein are useful indices for renal dysfunction by chronic exposure to Cd. The target group was 184 inhabitant(82 men and 102 women) in an abandoned mine area known as exposure to low level Cd. The control group was took 160 individuals(64 men and 96 women) in Cd not-exposed area. Urinary Cd concentration was significantly higher in the target group than the control. The geometric mean of urinary Cd for male was $2.56{\mu}g/\ell,\;2.80{\mu}g/g$ creatinine and $2.50{\mu}g/S.G.$ in the target group and $1.19{\mu}g/\ell,\;1.36{\mu}g/g$ creatinine and $1.17{\mu}g/S.G.$ in the control. For female $2.69{\mu}g/\ell,\;3.94{\mu}g/g$ creatinine and $2.63{\mu}g/S.G.$ in the target group and $1.27{\mu}g/\ell,\;1.97{\mu}g/g$ creatinine and $1.25{\mu}g/S.G.$ in the control, respectively. In addition, urinary Cd of the target group had affected by the period of residence and dietary habit for the rice and the vegetables from the target area. These findings suggest the chronic exposure to Cd of the target population. Mean excretion of urinary NAG, $\beta_2-MG$ and total protein were not significant between two groups. In the target group, urinary NAG activity and total protein were significantly correlated with urinary Cd, but $\beta_2-MG$ was not related. Urinary excretion of NAG, $\beta_2-MG$ and total protein were significantly increased in $10\leqq$ than in <2 of urinary Cd level. In $2\sim10$ group of urinary Cd level, the excretion of NAG significantly increased while not showed for $\beta_2-MG$. In present study, urinary excretion of NAG was relatively sensitive than $\beta_2-MG$ in chronic exposure population to low level Cd.
