Aggravation of natural environment, improvements in income, internet diffusion, spread of five-day work a week, and population aging seem very different from each other. However they boil down to consumption. These culture patterns are changing into environment-friendly and productive housing culture. In other words, people might tend to have frequent contacts with not only environment-friendly housing in bustling cities but also woods that is environment friendly materials in their leisure time. In the period of people young and old alike are in favor of woodcrafts, this study was conducted for giving information to who speicalized in woodcrafts. Furthermore, the study shows that other countries also added grain and figure to woodcrafts for visually appealing.

Purpose : The purpose of this study was to investigate the depression, self-efficacy, and stress level of middle-aged women and to identify the factors affecting on stress, and to provide base line data for the development of nursing intervention for stress reduction of middle-aged women. Methods : Participants were 200 middle-aged women aged 40 to 60 who live in Seoul and Gyeonggi Province. Data collection period was from March 1, 2019 to April 15. In this study, the questionnaire of life events-stress, depression scale, self-efficacy was used. Data were analyzed by average, standard deviation, minimum, maximum, correlation and regression using the SPSS Program 21.0. Results : The results of this study, the correlation between depression, self-efficacy and stress in middle-aged women, depression and self-efficacy (r=-.264, p<.001), self-efficacy and stress (r=-.279, p<.001) had a significant negative correlation, depression and stress (r=.268, p<.001) had a significant positive correlation. Depression and self-efficacy were the factors affecting the stress of middle-aged women. Depression was β =.207 (p<.001) and self-efficacy β =-.222 (p=.003). Depression had the greatest influence on stress, followed by self-efficacy. Conclusion : Middle-aged women are an important time to prepare for a successful old age. Considering that the current middle-aged women are the subjects of the future aging society, their physical, psychological, and social problems are very important in preventing the elderly problems of the aging society. Therefore, effective nursing interventions should be developed that to reduce the depression and stress in middle-aged women and to improve self-efficacy and improve the quality of life of middle-aged women.

Synaptic long-term potentiation (LTP) and long-term depression (LTD) have been studied as mechanisms of ocular dominance plasticity in the rat visual cortex. Serotonin (5-hydroxytryptamine, 5-HT) inhibits the induction of LTP and LTD during the critical period of the rat visual cortex (postnatal 3~5 weeks). However, in adult rats, the increase in 5-HT level in the brain by the administration of the selective serotonin reuptake inhibitor (SSRI) fluoxetine reinstates ocular dominance plasticity and LTP in the visual cortex. Here, we investigated the effect of 5-HT on the induction of LTP in the visual cortex obtained from 3- to 10-week-old rats. Field potentials in layer 2/3, evoked by the stimulation of underlying layer 4, was potentiated by theta-burst stimulation (TBS) in 3- and 5-weekold rats, then declined to the baseline level with aging to 10 weeks. Whereas 5-HT inhibited the induction of LTP in 5-week-old rats, it reinstated the induction of N-methyl-D-aspartate receptor (NMDA)-dependent LTP in 8- and 10-week-old rats. Moreover, the selective SSRI citalopram reinstated LTP. The potentiating effect of 5-HT at 8 weeks of age was mediated by the activation of 5-$HT_2$ receptors, but not by the activation of either 5-$HT_{1A}$ or 5-$HT_3$ receptors. These results suggested that the effect of 5-HT on the induction of LTP switches from inhibitory in young rats to facilitatory in adult rats.

The re-unification of the two Koreas is seen as a potential solution to the aging problem and low fertility, along with the increase in the old population structure of the Republic of Korea. Population structure is an indicator of national competitiveness or growth, but little is known officially about the populations of Democratic People's Republic of Korea (DPRK). Understanding the population structure of the DPRK is important to prepare for re-unification and estimate the socio-economic costs of national welfare under a re-unified Korea. In this paper, we assess reliability of the two modern national censuses of DPRK and use the limited resources available to reconstruct the intercensal populations between these two censuses. Excess deaths from the 1995 famine are estimated at 489,972 to 574,306 and are close to the estimates of Goodkind et al. (2011) and the reconstructed populations in the of DPRK implies a big difference between two Koreas.

The suspension system of railway rolling-stock is composed of the primary and secondary suspension elements. Recently, a conical rubber spring is widely used as the primary suspension element due to the merits of the three directional stiffness characteristics. So, understanding the properties and characteristics of the conical rubber spring is very important from the viewpoint of vehicle stability and efficient maintenance. Thus, this study is started to acquire the basic data for maintaining spring elements efficiently. For this, we tested the conical rubber spring samples including a new and old specimen with aging. As a test result, we have obtained the property characteristics of the aged spring comparing with the new product and we describe the results.

This study is to investigate the patients who had blepharoplasty for cosmetic purposes or facial nerve disorders. 21 patients were examined with an age from 17 to 63 years. Sixteen cases were classified as a normal group for investigation of the histopathologic change according to the age. The rest were patients of Bell's palsy(2), $Botox^{(R)}$ injection(2) and blepharospasm (1). We measured a mean diameter of myofiber and dimension's proportion of muscluar tissue per regular visual field. First, we measured a statistical significance according to the age in normal cases by grouping them into younger than 30-year-old, 30's, 40's, 50's and 60's. Second, we divided normal cases(16) into Group A and B by two bases for statistical analysis. In conclusion, although there were several differences as vacuolation, internalization of sarcolemnic nuclei between 35-year-old and 62-year-old patients in simple comparison, there was no uniform decrease according to the age. There were also no significant statistical changes in the value of a diameter of myofibers and dimension's proportion of muscular tissue according to the age in any of the two normal groups. But in $Botox^{(R)}$ injection and Bell's palsy, blepharospasm patients, two values showed remarkable difference compared to the normal group of same age.
