This study aims to investigate the relationship between quality of life, activities of daily living, and depression among Korean super-aged women. In this study, the 7th (2018) data of the Korean Longitudinal Study of Aging (KLoSA) were used. The participants in this study were 363 super-aged women. The mean age was 88.67 years old. Quality of life was significantly related with Activities of daily living (ADL) (r = .34, p < .001), and depression (r = -.47, p < .001). The analysis of the hypothesized model showed a good fit to the data except for the χ² value (χ² = 38.8, df = 11, p < .001, CFI = .98, TLI = .96, RMSEA = 0.08). The hypothesized model explained 34% of the variance in super-aged women. The activities of daily living of elderly women had an indirect effect on quality of life via depression. Very old women with a high level of ADL were more likely to be feeling less depression, and elderly people who had less depression were likely to have a better quality of life. The findings thus highlight prevailing depression and activities of daily living as critical foci for clinical management strategies in super-aged women.

Age and growth of stone flounder kareius bicolortus in approaches to Kyongyolbiyolto of Yellow sea were studied by otolith reading of 248 fishes from September 1992 to August 1993. Examination of the ourter margins of the otoliths showed that th hyaline zone as annulus was formed once a year and that its formation was completed at the end of the spawning season(Jan. to Feb.). Growth of the fish was expressed by the von Bertalanffy's equation as Lt=313.7[1-exp{-0.463(t+0.0704)}] for males and Lt=478.6[1-exp{-0.286(t-0.1619)}] for females, where Lt is body length in mm and It is age in years. It was found that growth of males and females differs, with the females showing a higher growth than the males. Growth in body weight was also examined. The oldest fish were seven years old for males and females.

This study was carried out to establish an effective and practical system for commercialization of embryo production techniques by analyzing several factors influencing in vivo embryo production on condition of donors treated FSH-P and SUPER-OV in Korean native cattle. In vivo embryos were flushed 226 times from 128 donors. The results obtained for the factors influencing in vivo embryo production by conditionof donors treated FSH-P and SUPER-OV were as follows :1. Age and parity of donors did not affect the transferable and freezable embryos among the treatments in FSH-P but the transferable and freezable embryos were decreased after 6 years old and 4th parity in SUPER-OV(P<0.01). 2. The production of embryos on the weight of donors was higher in over 400kg of body weight in FSH-P(P<0.01) and was higher in over 450kg than 400~450kg of body weight in SUPER-OV(P<0.05). For FSH-P embryo production was better responded in 350~450kg of body weight with 30~32mg doses, and showed a better result in over 450kg body weight with 32~34mg doses.(Key Words : in vivo embryo, donors, FSH-P SUPER-OV)

Recent observations and modeling of globular clusters with multiple populations strongly indicate the presence of super helium-rich subpopulations in old stellar systems. Motivated by this, we have constructed new population synthesis models with and without helium-enhanced subpopulations to investigate their impact on the UV-upturn phenomenon of quiescent early-type galaxies. We find that our models with helium-enhanced subpopulations can naturally reproduce the strong UV-upturns observed in giant elliptical galaxies assuming an age similar to that of old globular clusters in the Milky Way. The major source of far-UV (FUV) flux, in this model, is relatively metal-poor and helium-enhanced hot horizontal branch stars and their progeny. The Burstein et al. (1988) relation of the FUV - V color with metallicity is also explained either by the variation of the fraction of helium-enhanced subpopulations or by the spread in mean age of stellar populations in early-type galaxies.

Background: Increasing numbers of super-elderly patients (>80 years old) with cancer now require microvascular-free tissue transfer. The objectives of this study were to evaluate potential applications of microvascular tissue transfer in this patient population, and post-surgical changes in quality of life. Methods: The records of cancer patients 80 years or older who had undergone microsurgical tissue transfer were retrospectively reviewed. Structured interviews were conducted with patients and family caregivers after surgery, and the patients' quality of life was qualitatively assessed. Results: The study cohort consisted of seven patients with a mean age 87.6 years (range, 81 to 95). Wound and medically-related complications were minimal. During the patient interviews, eight of the nine respondents reported remarkable improvements in quality of life following surgery and expressed a high level of satisfaction with their surgical results. Conclusions: Our study showed that microsurgical reconstruction performed in super-elderly patient not only appropriately repairs post-oncologic defects but also significantly improves the patients' quality of life.

The weight of elderly people in Korea has been increasing. Statistics show that the percentage of the elderly people in Korea was 3.1% in 1970; 3.8% in 1980; 5.1% in 1990, and 7.2% in 2000. Based on this trend, thus, the number of elderly people could be estimated to be 14% of the whole Korean population in 2018. This reveals that Korea is entering a super-aging society with remarkable fast pace. In such a change, the statistics related to elderly people driving license and the occurrence of traffic accidents are showing a noticeable numerical value. The number of traffic accident fatality in Korea ranks the highest value in OECD Countries. However, the research on old drivers in the nation is going on partially centering on system improvement and management scheme. Thus, first of all, researches about the linkage & characteristics between the driving behavior of old drivers and traffic accident should be implemented, in order properly to draw system improvement and management scheme for the old drivers. Therefore, the focus of this study is the influence model for discerning the severity of the age-old-caused traffic accidents by inquiring into the relation between the Driving Aptitude Test items that make it possible to measure their behavioral characteristics and influential factors by age group on the basis of the data on traffic accidents. The analysis results can be used as basic data for suggesting the behavioral research and countermeasure for traffic safety and its management for old driver in preparation for the aging society.

Korea has entered to 'aged society', which the elderly people over 65 years old is over 14% of total population. This paper aims to analyze the traffic accident by aging level. In pursuing the above, this paper focuses on modeling the traffic accident severity based on three aging levels. The main results are as follows. First, the ratio of fatal and serious injured persons (FSI) is judged to increase according to increasing aging level. Second, the null hypothesis that there is no difference in FSI among three aging levels (aging, aged, and super-aged) is rejected. Four accident severity generalized linear models which are all statistically significant have been developed. Third, the common variables are analyzed to be median age, the number of hospital beds per persons, and turn signal usage ratio. Fourth, the differentiated traffic safety policies fitted to aging levels are required. The enforcement of traffic law violation and safety enhancement of motorcycle in the region of 'aging society', improvement of traffic facilities in the region of 'aged society', and expansion of transportation facilities in the region of 'super-aged society' are evaluated to be indispensable.

This study was carried out to establish an effective embryo production system by analyzing several factors ifluencing in vivo embryo production in Hanwoo. The results are summarized as follows : 1. The number of total, fertilized and transferble embryos by gonadotropins were no significant difference among PMSG, FSH and FSH+PMSH. 2. The numbers of recovered and transferable embryos by type of FSH were no significant difference in both FSH-P and FOLLTROPIN-V but significant difference with SUPER-OV(p<0.01). 3. The numbers of recovered and transferable embryos by age of donor were highest in 5 years old. 4. The recovered number of transferable embryos was highest in the cows at the 1 st and 3rd parity but significantly lower in hifers and the cows at more than 6th parities(p<0.01). 5. The numbers of trasferable embryos by postparient were more<270 days than > 270 days in significant difference(p<0.01). 6. Embryo production after treatment of repeated super ovulation was no significant difference. 7. Recovered and trasferable embryos production after treatment of repeated super ovulation interval was highest 81∼100 days and significant difference(p<0.01). 8. The numbers of recovered and transferable embryos by seasons were no significant difference.

The superior gluteal artery perforator flap technique has increasingly been used for soft tissue defects in the sacral area following its introduction nearly 25 years ago. Advantages in covering sacral defects include muscle sparing, versatility in design, and low donor side morbidity. The bilateral superior gluteal artery perforator flap procedure is planned in cases of large sacral defects that cannot be covered with the unilateral superior gluteal artery perforator flap. Here, we report two cases of large sacral defects in which patient factors of poor general health, such as old age, pneumonia, and previous operation scar, led to use of a large unilateral superior gluteal artery perforator super-flap with parasacral perforator. The approach was utilized to reduce the operation time and prevent unpredictable flap failure due to the large flap size. Even though the parasacral perforator was included, the versatility of the large superior gluteal artery perforator flap was preserved because sufficient perforator length was acquired after adequate dissection.

The purpose of this research is to secure the foundational data for analyzing the mediating role of social capital from the influences of the feeling of self-efficacy of the elderly on the preparations for the old age. The subjects of this study were 518 questionnaires collected from March 20 to April 1, 2016 for the elderly over 60 years old who were living in S city. Regarding the data, the SPSS 20.0 and the AMOS 20.0 were used. And, the results of this research were the following: First, if we take a look at the influences of the feeling of self-efficacy on social capital, the feeling of self-efficacy has the positive influences. And, second, the influences of the feeling of self-efficacy on the preparations for the old age, also, are positive. Third, the influences of the social capital on the preparations for the old age, too, are positive. As such, we can find out that both the direct and indirect effects were shown. Lastly, we can find out that the feeling of self-efficacy has the partial mediating effects on the social capital and the preparations for the old age. Consequently, although the feeling of self-efficacy is insufficient with regard to the economic preparations, we can positively find out that it was able to effectively derive the satisfaction in life by utilizing the social capital. In preparation for the super-aged society, the improvements and the expansions of the social programs and the services resulting from them are needed through the establishment of a foundation regarding the life-periodical, social participation, the establishment of a socially-shared system that can be continued, and the policy of strengthening the social capital.
