Enteral nutritional support has been used via tube feeding for dysphagic stroke patients. We performed long and short term trials to evaluate the effects of commercial enteral nutritional supports on nutrition and health in stroke patients (mRS = 3~5) and quality of life in their caregivers. For a long term study, we recruited chronic (${\geq}$ 1 yrs) stroke patients (n = 6) and administered them 6 cans/day (1,200 kcal) of the commercial enteral formula N for 6 months according to IRB-approved protocol. We collected peripheral blood at 0, 2, 4 and 6 months. For a short term study, we recruited acute (${\leq}$ 3 months) stroke patients (n = 12) and randomly administered them two different commercial enteral formulas, N or J, for 2 weeks. We collected their blood at 0, 4, 7 and 14 day of the administration. Blood samples were analyzed to quantify 19 health and nutritional biomarkers and an oxidative stress biomarker, malondialdehyde (MDA). In order to evaluate quality of life, we also obtained the sense of competence questionnaire (SCQ) from all caregivers at 'before' and 'after trials'. As results, the enteral formula, N, improved hemoglobin and hematocrit levels in the long term trial and maintained most of biomarkers within normal ranges. The SCQ levels of caregivers were improved in the long term treatment (P < 0.05). In a case of the short term study, both of enteral formulas were helpful to maintain nutritional status of the patients. In addition, MDA levels were decreased in the acute patients following formula consumption (0.05 < P < 0.1). Most of health and nutrition outcomes were not different, even though there is a big difference in price of the two products. Thus, we evaluate the formula N has equal nutritional efficacy compared to the formula J. In addition, long term use of enteral formula N can be useful to health and nutrition of stroke patients, and the quality of life for their caregivers.

Physical education bodybuilders compete by means of external appearance, and more and more people are starting bodybuilding with an interest in improving their individual constitution and diet. However, some of the bodybuilders in sports for life started using banned substances to show off their appearance or to expect good results in bodybuilding competitions. Prohibited drugs only have a short-term positive effect on the subject, and the seriousness of side effects was greater when taking the drug for a long time. An education program that can provide professional education and information on drugs to bodybuilding athletes for life sports should be preceded, and a system that can check regular health should be introduced if necessary. A periodic doping education program for bodybuilders for sport for life is needed to focus on the positive changes in bodybuilding through banned substances and to educate and understand the side effects and damage to life that occur later. Therefore, in order to prevent doping, it is essential to educate various aspects of doping, and it is required to expand the scope not only to elite athletes but also to participants as sports for all

The majority of childhood cancer survivors and their families will be psychologically healthy, but may desire and benefit from preventive care. A significant portion of the survivor population will be psychosocially distressed in various aspects by their harsh experience of long cancer treatment, and may warrant professional intervention and treatment. Pediatricians should be aware of the late psychological effects that can occur a year or 2 after treatment, possibly in many aspects of a survivor's life. Not only the cancer diagnosis, but also treatments such as chemotherapy, irradiation, and surgical intervention may exert different long-term effects on the psychosocial outcomes of survivors. Pediatricians need to be more concerned with maintaining and improving the psychological health of this growing number of childhood cancer survivors through long-term follow-up clinics, community support, or self-help groups. Research on all of the psychosocial aspects of childhood cancer survivors is important to recognize the reality and problems they face in Korea.

When natural rubber is used for a long period of time, it becomes aged; it usually becomes hardened and loses its damping capability. This aging process affects not only the material property but also the (fatigue) life of natural rubber. In this paper the aging effects on the material property and the fatigue life were experimentally investigated. In addition, several fatigue life prediction equations for natural rubber were proposed. In order to investigate the aging effects on the material property, the load-stretch ratio curves were plotted from the results of the tensile test, the compression test and the simple shear test for virgin and heat-aged rubber specimens. Rubber specimens were heat-aged in an oven at a temperature ranging from $50^{\circ}C$ to $90^{\circ}C$ for a period ranging from 2 days to 16 days. In order to investigate the aging effects on the fatigue life, fatigue tests were conducted for differently heat-aged hourglass-shaped and simple shear specimens. Moreover, finite element simulations were conducted for the specimens to calculate physical quantities occurring in the specimens such as the maximum value of the effective stress, the strain energy density, the first invariant of the Cauchy-Green deformation tensor and the maximum principal nominal strain. Then, four fatigue life prediction equations based on one of the physical quantities could be obtained by fitting the equations to the test data. Finally, the fatigue life of a rubber bush used in an automobile was predicted by using the prediction equations, and it was compared with the test data of the bush to evaluate the reliability of those equations.

Objectives: The current study aims to examine whether the influence of National Long-term Care Insurance(NLCI) on the quality of life(QoL) trajectory of older adults with disabilities is more positive than its influence on those without disabilities. Methods: Sample consisted of 5,362 elderly aged 65 and over who participated in the Korean Welfare Panel Study from Wave1 to Wave7. Data were analyzed using latent growth curve modeling. Results: Major findings are as follows. (1) Before the NLCI, the trajectories of QoL between older adults with disabilities and those without were same. (2) After the NLCI, elders with disabilities showed lower levels of QoL at the beginning, but the gaps gradually decreased with time. These results indicate that the implementation of NLCI more positively affected elders with disabilities than those without disabilities. Conclusions: These results suggest that the NLCI functions properly as one of social security nets to cope with the needs of older adults with disabilities. In conclusion, it is critical to develop a sustainable NLCI system to enhance the QoL of older adults with disabilities.

Esophageal cancer is a representative cancer that occur physical deterioration but, physical problems after surgery were not well reported. The purpose of this study is to report on the long thoracic neuropathy after surgery, and to identify the symptoms and effects of physical therapy after esophageal cancer surgery. This is a case of a 61-year-old man who showed winging of the scapula with long thoracic nerve injury on the results of electromyography after an esophageal cancer surgery. Physical therapy programs were implemented 8 sessions during hospitalization. The quality of life, fatigue, shoulder range of motion (ROM), numeric rating scale (NRS), 6-minute walk test, and 30-second chair stand test were assessed. The quality of life, fatigue, shoulder ROM, NRS (pain), 6-minute walk test, and 30-second chair stand test were improved. However, the esophageal-specific symptom was not different after physical therapy program. As esophageal cancer suffers from physical difficulties after surgery, physical therapy programs are thought to be helpful.

Purpose: This study was conducted to examine the late effects, social adjustment, and quality of life in adolescents who had been completely treated for childhood leukemia and their parents. Methods: Participants consisted of 41 pairs of adolescent survivors (13-18 years) and their parents. Parents checked for their child's physical late effects. The Korean Version of Post-Traumatic Symptoms for psychological late effects, social functioning questionnaire for social adjustment and the PedsQL 4.0 Generic Core Scales for quality of life were completed by adolescents and parents. Data were analyzed using SPSS. Results: Twenty out of 41 adolescents had one or more physical late effects. Adolescents showed more serious psychological late effect than parents. Five children and seven parents had above cut-off scores and they were considered the high risk group for posttraumatic symptoms. Parent-reported scores were significantly higher than child-reported scores in terms of social adjustment and emotional functioning of quality of life. Low school functioning in adolescents was associated with physical late effects. Conclusion: The results indicate that long-term and systematic management for childhood leukemia survivors affect positive social adjustment and can further improve quality of life.

Melatonin is a pineal hormone that is synthesized and released at night under the light and dark cycles of a day. Its effects on the reproductive activities have well been established by the administration through various routes in photoperiodic animals. It was also identified in plants and named phytomelatonin. The capacity of the phytomelatonin was investigated in this investigation whether it affects the reproductive function in male golden hamster. As expected, animals housed in long photoperiod (long photoperiod, LP>12.5 hours of lights in a day) had large testes and animals kept in short photoperiod ($$SP{\leq_-}12.5$$ hours of lights in a day) showed remarkably reduced testes. The dietary supplement with melatonin itself induced the complete involution of testes. Pistachios that were reported to contain a large amount of melatonin demonstrated no effects at all in male golden hamsters. These results suggest that dietary supplement containing melatonin-rich foodstuff used in this investigation may not be enough to affect the reproductive endocrine system in male golden hamsters.
