The purpose of this study is to investigate the relationship between always being on call and the conflict factors between work and life balance among employees' in the IT relative industry. The results are as follows: always being on call factor perceived by employees' in the IT relative industry influences to conflict factor between work and life balance. Moreover, always being on call factor negatively effects on all factors of job insecurity which are impotent feeling and possibility of job loss. From the analysis of relation between job insecurity and conflict between life and work balance showed that the factor of impotent feeling influence on conflict between life and work balance while the factor of job loss does not. In addition, job insecurity(impotent feeling and possibility of job loss) partially mediated between always being on call and the conflict factors between work and life balance among employees' in the IT relative industry.

To evaluate the resistance of wood to decay caused by fungi, sapwood and heartwood of red pine (Pinus densiflora) and sapwood and heartwood of larch (Larix kaempferi) were conducted. Wood samples were immersed for 96 h in pyroligneous liquor. Then, the brown-rot fungus, Fomitopsis palustris, was used to examine the decay resistance of red pine and larch. Weight and density of wood from the all conditions increased after immersion treatment. Weight loss after decay resistance test was also dropped with a immersion treatment. The lowest weight loss indicated at immersion-treated heartwood of larch. Immersion treatment using pyroligneous liquor effectively increased the resistance of wood to decay caused by fungi.

Hair follicles in the skin undergo cyclic rounds of regeneration, degeneration, and rest throughout life. Stem cells residing in hair follicles play a pivotal role in maintaining tissue homeostasis and hair growth cycles. Research on hair follicle aging and age-related hair loss has demonstrated that a decline in hair follicle stem cell (HFSC) activity with aging can decrease the regeneration capacity of hair follicles. This review summarizes our understanding of how age-associated HFSC intrinsic and extrinsic mechanisms can induce HFSC aging and hair loss. In addition, we discuss approaches developed to attenuate ageassociated changes in HFSCs and their niches, thereby promoting hair regrowth.

From 1953 to 2015, approximately 200,000 children born in Korea were adopted into foreign countries. Many studies have focused on Korean adoptees growing up in the US, as the majority of these children were adopted by American families. In comparison, research on Korean transracial adoptees raised in European countries is limited. Thus, the current study aims to highlight the journey of Korean transracial adoptees from Europe to Korea. Three participants narrated their life stories as adoptees in two separate interview sessions. The findings of this study call attention to the adoptees' ongoing reconsideration of their identity as they assimilate life experiences within two disparate cultural settings in Europe and Korea. The study found that ambiguous loss faced by the adoptees from their childhood in Europe continued to their adulthood in Korea. Major themes of the participants' narratives in their journey from Europe to Korea focused on their feelings of loss and the lack of belongingness. This study found that the sense of loss and the lack of belongingness changed over time. Participants were active agents in the process of their journey from Europe to Korea, as they constantly worked to adapt to and improve their situation in face of adversity.

Threshing loss was increased due to dropping of the threshing efficiency when the 4 row head-feed combine harvested 5 row rice to improve harvesting performance of a combine. Reasonable design criteria were examined to determine the ranges of both of feed rate and the length of threshing drum for the 4 row head-feed combine being used as a 5-row combine. Harvesting performance increased as working width or working speed increased, it resulted in 15% increase when the working width increased from 4 row to 5 row. Harvesting operations of the 4 row combine performed normally in the 4 row rice in threshing loss less than 1%, however, threshing loss increased to 2.25% in the 5 row due to poor threshing efficiency. The length of threshing drum was increased from 710 mm to 810 mm as well as the speed of crop feed chain was increased from 0.61 m/s to 0.75 m/s so as to improve the poor threshing efficiency resulted from the enlarged working width from the 4 row to the 5 row, which would decrease threshing loss less than 1%.

Humans have acquired many distinct evolutionary traits after the human-chimpanzee divergence. These phenotypes have resulted from genetic changes that occurred in the human genome and were retained by natural selection. Comparative primate genome analyses reveal that loss-of-function mutations are common in the human genome. Some of these gene inactivation events were revealed to be associated with the emergence of advantageous phenotypes and were therefore positively selected and fixed in modern humans (the "less-ismore" hypothesis). Representative cases of human gene inactivation and their functional implications are presented in this review. Functional studies of additional inactive genes will provide insight into the molecular mechanisms underlying acquisition of various human-specific traits. [BMB Reports 2015; 48(7): 373-379]

The loss of nitrogen and phosphorus from sediments in two watersheds, one naturally regenerating and one artificially planted, in Sacheon-myun, Gangneung-si, Gangwon Province, were measured two years after a forest fire in 2000. Sediment losses occurred five times in the course of the year. In the artificially planted watershed, $50{\sim}140$ times more nitrogen and $54{\sim}139$ times more phosphorus were lost with sediments during heavy rains, from July to August, than in the naturally regenerating watershed. When the typhoon Rusa struck the country, 1,389 times more nitrogen and 1,647 times more phosphorus were lost from the artificial watershed. In spite of the limited scope of this study, these results suggest that artificially planted watersheds are extremely vulnerable to catastrophic natural disasters such as typhoons. Elevated loss of nutrients in the artificially planted watershed might have resulted from the mechanized silvicultural practices employed immediately after the fire. To maximize soil preservation, the timing and necessity of plantation practices should be reconsidered, and rapidly regenerating vegetation should be protected to promote nutrient uptake and to mitigate nutrient loss from burned forests.

The purpose of this study is to examine the mediating effect of a sense of self-integration in the relationship between death anxiety and death anxiety on the quality of life for the elderly living in rural areas. First, death anxiety among the elderly living in rural areas was found to have a negative effect on the quality of life, and among the sub-elements of death anxiety, the anxiety of loss of existence and the anxiety of the death process were negative on the quality of life. Second, it was found that there is a positive effect on the sense of self-integration, which is a parameter such as anxiety about loss of existence, anxiety about the death process, and anxiety about post-mortem outcomes. Third, it was confirmed that the sense of self-integration mediates between death anxiety and quality of life. Based on the results of this study, several discussions and suggestions were made to improve the quality of life of the elderly living in rural areas by improving the sense of self-integration and reducing death anxiety.

The word "Loss" means being deprived a person's meaningful property, people or idea by irresistible force, and it is not avoidable in one's life. Especially, the elderly have higher possibility to experience this "Loss" than any other age groups on account of their characteristics. Feeling grief of loss after going through any kind of loss is natural and normal. However, if someone has severe trouble with overcoming this grief, it would affect negatively to his/her psychological or social inelastic. Therefore, we tried to find out which factors consists the "Grief of loss" and how it affects on the elderly's quality of life, especially on the sense of ego-integrity through this study. 97 of the elderly over age 65 participated in the survey and the results as follow; grief of loss is classified into four factors, 'economical loss', 'loss from being parted by death', 'loss of physical functions' and 'loss of relations'. These four factors of "Grief of loss" showed negative correlations with the scores of the sense of ego-integrity factors except 'acceptance of death'. Especially, the 'economical loss' affects on every factor of the sense of ego-integrity negatively except 'acceptance of death' and 'acceptance of aging'. Moreover, 'loss of physical functions' and 'loss of relations' affect negatively on elderly's satisfaction to their lives. On the other hand, the 'loss from being parted by death' of "Grief of loss" and 'acceptance of death' of the sense of ego-integrity showed no statistically significant effect in every process of analysis.
