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.

In this study, we analyze the relationship between long-term care workers' emotional labor, professional quality of life, and service quality. The subjects of this study were 211 long-term care workers working in long-term care facilities. Self-administered questionnaires were used. In the research model, emotional labor(surface behavior, internal behavior) was verified using independent variables, with professional quality of life (compassion satisfaction, compassion fatigue) as the parameters and service quality as the dependent variables. The results of this study are as follows. First, the fit of the model was good. Second, the direct effects of emotional labor on service quality were not significant. However, there was a positive correlation between internal behavior and service quality, and a negative correlation between surface behavior and service quality. Third, professional quality of life(empathy satisfaction) was the most influential variable in terms of service quality. The results of this study demonstrate the necessity to payclinical and academic attention to long-term care workers' emotional labor and quality of life.

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.

The purpose of this study was to evaluate the status of oral health care in dementia patients living in long-term care facilities and to investigate the effects of this on swallowing function and swallowing-quality of life. The subjects were 60 demented patients who were admitted to long-term care facilities in Gwangju and Jeonnam provinces. Their Oral Health Assessment Tool(OHAT), Clinical Dysphagia Scale(CDS), and Oral Health Impact Profile 14(OHIP-14) were measured. The results of this study were as follows: First, the effect of oral health care on dentition patients using long-term care facilities on swallowing function and swallowing-quality of life was significantly different according to oral care score (p<.05)(p<.01). Second, the relationship between oral health care and swallowing function of dementia patients and swallowing-quality of life. was examined. As a result, oral health care of dementia patients was affected by swallowing function (r=.405, p<.01) the swallowing-quality of life (r=.462, p<.01) and swallowing function were significantly correlated with swallowing-quality of life (r=.351, p<.01). Therefore, the oral health care of users of long-term care facilities was closely related to swallowing function and swallowing-quality of life.

This paper employs an Overlapping Generations Model to quantify the impacts of Korea's demographic transition toward an older population on the total output growth rate. The model incorporates the projected population through 2060 according by Statistics Korea. The effects of the low fertility and increased life expectancy rates are studied. The model is considered suitable for analyzing the effects of demographic changes on the Korean economy. Under the assumption that the TFP growth rate will not slow considerably in the future, remaining at 1.3% per annum, the gross output growth rate of the Korean economy is projected to slow to 1.1% per annum in the 2050s, from 4.0% in the 2000s. The shrinking workforce due to the decline in fertility plays a significant role in the deceleration of the Korean economy. The increased life expectancy rate is expected to mitigate the negative effect, but the magnitude of its effect is found to be limited.
