  • Normal aging causes changes in the brain volume, connection, function and cognition. The brain changes with increases in age and difference of gender varies at all levels. Studies about normal brain aging using various brain magnetic resonance imaging (MRI) variables such as gray and white matter structural imaging, proton spectroscopy, apparent diffusion coefficient, diffusion tensor imaging and functional MRI are reviewed. Total volume of brain increases after birth but decreases after 9 years old. During adulthood, total volume of brain is relatively stable. After 35 years old, brain shrinks gradually. The changes of gray and white matters by aging show different features. N-acetylaspartate decreases or remains unchanged but choline, creatine and myo-inositol increase with aging. Apparent diffusion coefficient decreases till 20 years old and then becomes stable during adulthood and increase after 60 years old. Diffusion tensor properties in white matter tissue are variable during aging. Resting-state functional connectivity decreases after middle age. Structural and functional brain changes with normal aging are important for studying various psychiatric diseases such as dementia, schizophrenia and bipolar disorder. Our review may be helpful for studying longitudinal changes of these diseases and successful aging.

  • The purpose of this study was to compare the risk factors of dyslipidemia by age group in 19 years and over in Korea. The participants of this study were 12,506 adults aged 19 and over who attended the 6th (2013~2015) National Health and Nutrition Survey. As a result of male risk factors, the 19-59 years old group were marital status, obesity, abdominal obesity, smoking, physical activity, hypertension, diabetes and subjective health status. Obesity, abdominal obesity, drinking, hypertension and diabetes were group over 60 years old. As a result of female risk factors, the 19~59 years old group were education, marital status, obesity, abdominal obesity, smoking, physical activity, hypertension, diabetes and perceived health status. Abdominal obesity, hypertension and diabetes were group over 60 years old. Based on these results, a strategy for health promotion according to gender and age should be prepared in order to prevent dyslipidemia.

  • Life history of the Siberian stone loach, Orthrias toni, were investigated using samples collected from Buk Stream, Goseong-gun, Gangwon-do, Korea. Growth was rapid between April and October when water temperature exceeded $10^{\circ}C$, but growth almost stopped from November-March when water temperature was below $10^{\circ}C$. Age groups for O. toni estimated by frequency distribution of total length in spawning season (May) indicated the 60~81 mm is 1-year old, the 82~99 mm group is 2-years old, the 100~119 mm is 3-years old, and the 120~140 mm is more than 4-years old. Total length range by sex was similar, and sex ratio (♂/♀) was 0.73. Spawning season according to the gonadosomatic index (GSI) was May with water temperature $14{\sim}17^{\circ}C$, and almost all fish were mature after one year old. Fecundity increased rapidly with age with an average of $4,460{\pm}3,302$ ($mean{\pm}SD$). Size of mature eggs was $0.87{\pm}0.03mm$ in diameter irrespective of age.

  • Wolf teeth have been reported with incidence rate of 13% to 31.9% in horses of both sexes. However, there is no report about the incidence of wolf teeth in pony breeds. In order to determine the incidence of wolf teeth in Jeju Ponies and Jeju Pony crossbreds, oral examination and palpation of the interdental space of ponies at the Jeju Race Park were performed from 2006 to 2010. Results of this study showed that a total of 90 (3.4%) of the 2,675 examined Jeju Ponies and Jeju Pony crossbreds had wolf teeth. Among 30 Jeju Ponies that had wolf teeth, 22 were male (73.3%) and 8 were female (26.7%). Among 60 Jeju Pony crossbreds that had wolf teeth, 25 were male (41.7%) and 35 were female (58.3%). In Jeju Ponies, wolf teeth were most common in 3-years-old, followed by ${\geq}4$-years-old, then 2-years-old. For Jeju Pony crossbreds, wolf teeth were most common in 3-years-old, followed by 2-yearsold, then ${\geq}4$-years-old. In conclusion, the incidence of wolf teeth in Jeju Ponies and Jeju Pony crossbreds was considerably lower than what has been reported for horses in other countries.

  • Background: We performed this meta-analysis to assess the effectiveness and safety of axillary dissection in old women. Methods: The Cochrane Library, PubMed, EMBASE and Chinese Biomedical Literature Database were searched and all randomized controlled trials of axillary dissection in old women (at least 60 years old) were considered. Meta-analyses were completed using RevMan5.1. Results: Three eligible randomized controlled trials (RCTs) including 5,337 patients were considered. There was weak evidence in favour of axillary dissection (AD) in old women. The meta-analysis showed that the overall survival (OS) after 1, 3, 5 and 7 years and the disease free survival (DFS) after 1, 3 and 5 year were not statistically significantly different between AD and no AD groups. However, there was a difference in the 7 year DFS. Conclusions: Axillary dissection did not provide survival benefit to the old women with breast cancer analysed. Therefore, axillary dissection is not well-indicated in old women with breast cancer.

  • The present study conducted a stem analysis to trace growth information of Japanese larch (Larix kaempferi) and predict the future changes in growth volume. For this purpose, six L. kaempferi trees over 47 years old were cut at 1-2 m intervals from a height of 0.2 m, and circular plates of 5 cm thickness were collected for stem analysis. The analysis indicated that approximately 1-8 years are required to grow up to chest height. The annual height and diameter growth increased rapidly until the trees are 15 years old and gradually decreased after 20 years. The volume of 30-year-old trees in Oegam-ri forests, which were well-managed after artificial reforestation, was 0.4837 m3, whereas that in unmanaged Singi-ri forests was 0.1956 m3. Although the volume of individual trees differed greatly depending on the forest management status, it was found that the volume increased by 1.67-1.76, 2.49, and 3.49 times at 40, 50, and 60 years age, respectively, compared to the legal harvesting age 30. Therefore, factors such as the carbon dioxide reduction effect, forest management benefits, and the condition of trees at the site should be considered before harvesting trees.

  • The purpose of this study was to identify correlation of stress, coping patterns and physical symptoms in cancer patient's caregiver. The stress was measured by VAS(Visual Analogue Scale). The coping methods were measured using the modified Ways of Coping Questionnaire by Yang (1998) and the actual physical symptoms were investigated. The phases of patient illness consisted of 1st (initial) stage, and 2nd (recurred) stage and 3rd (terminal) stage based on literature (Lewandowski & Jones, 1988). The data were collected by a survey conducted from March to July, 2000 and which included 196 cancer patients' caregivers from two hospitals in Seoul. The data were analyzed using paired t-test, unpaired t-test, ANOVA, Scheffe test and Pearson correlation coefficient. The results were as follows: 1. The average of caregivers' stress scores was 62.5. Problem-focused coping methods were significantly used more than emotion-focused coping methods by the cancer patients' caregiver. The mean number of caregivers' physical symptom was 1.03. 2. There were significantly high level of stress in women, those who were more than 60 years old, those who had a low education level, those who had no job, those who are patients' wives' and those who are terminal patients' caregiver. There were significantly low levels of coping in women, those who were more than 60 years old, those who had low education levels, those who had no job and those who are patients' wives. There were significantly higher number of physical symptoms in women, and those who have no job. 3. Caregivers' stress was significantly correlated to problem-focused coping methods (r=-.21, p=.006), and physical symptom (r=-.28, p=.0001). In conclusion, attempts to develop nursing interventions for cancer patients' caregiver in women, those who are more than 60 years old, with a low education level, have no job, and are cancer patients' wives could have an improvement on positive coping methods and provide relaxation from stress in the patients' experience.
