현재 우리나라는 초고령화 사회로 변화되어 가고 직장인은 주된 일자리에서 평균 49.5세에 퇴직하며, 국민연금은 현재 62세에서 2034년까지 65세로 늦춰지는 상황에서 직장인의 퇴직 이후 고령화에 대비한 연구가 필요함. 전국 직장인들을 대상으로 퇴직이후 창업의도에 영향을 미치는 요인과 퇴직이후 삶에 대한 또 다른 성공기대감의 매개효과를 규명하고자 한다. 퇴직이후 100세까지 지속가능한 직업, 즉 직장생활 속 지혜와 경험을 살린 창업을 위한 준비를 할 수 있도록 개인의 태도변화와 체계적인 제도적 지원이 필요하다. 연구결과, 직무수행능력인 목표수행능력, 노후준비도인 경제적 준비, 외적관계준비 및 미래불안감은 창업의지에 정(+)의 영향을 미치고, 직무수행능력인 신기술활용능력, 노후준비도인 신체적준비, 내적관계준비는 영향을 미치지 않는 것으로 나타났다. 외적관계준비와 창업의지, 미래불안감과 창업의지 간의 영향관계에서 또 다른 성공기대감은 부분매개 효과가 확인되었다. 경제적준비와 창업의지 간의 영향관계에서는 완전매개 효과가 확인되었다. 퇴직이후의 창업의지를 높이기 위해서는 또 다른 성공기대감이 중요한 변수임을 확인하였다. 잠재적 창업자인 직장인이 재직하는 동안 초고령화에 따른 정부의 재정적 부담도 줄이고 직원교육을 통한 기업의 성장도 이룰 수 있도록 정부지원의 교육시스템을 회사 내에 도입, 직장인의 인생 3모작을 위한 기업가정신 및 목표수행능력 향상프로그램을 도입, 개인과 기업의 성장 및 정부의 재정 부담을 줄이는 해결책이 될 시사점을 얻을 수 있었다.

The sols prepared by dialyzing solutions, in which the hydrolyzed precipitates of TEOT or directly Ti(OC3H7)4 were resolved, were the nanoparticulate sol with the average particle size less than 7 nm and the anatase crystal phase. In the pH range of 1.5 to 2.9, the particle size of the nanoparticulate TiO2 sols (0.09 mol/ι) increased gradually upto 15 nm~26nm with the increase of pH in the initial aging state but the sols were transparent all the time, and stable without growin any more after 30 days. When the slipcasted porous alumina tubes were coated by the sol-gel dipping method, the minimum particle size and the aging time for forming the coated gel layer at the given pH were optimized. For obtaining the very thin crack-free and reproducible membrane coating, the use of a nanoparticulate TiO2 sol (0.09 mol/ι) aged for about 30 dyas at pH=2.0 was found to be the best.

BaTiO$_3$, powders were prepared by sol-gel process from different aging time and reaction temperature. Particle shape, size and crystal structure of prepared $BaTiO_3$ powders were analyzed by SEM, XRD and FT-IR. Effect of aging time alternation didn't particularly show up. Spherical nano-sized $BaTiO_3$ powders were obtained from condition more than reaction temperature $55^{\circ}C$, and obtained sintered $BaTiO_3$ powders of tetragonal phase from heat-treatment at $1,100^{\circ}C$.

This study investigates the dispersibility of carbon in carbon contained ammonium diuranate (C-ADU) gel particles and the characteristics of C-ADU gel liquid droplets produced by the vibrating nozzle and integrated aging-washing-drying equipment. It was noted that the excellent stability of carbon dispersion was only observed in the C-ADU gel particle that contained carbon black named CB 10. ADU gel liquid droplets containing carbon particles with the excellent sphericity of approximately 1,950 mm were then obtained using an 80-100-Hz vibrating nozzle system. Dried C-ADU gel particles obtained by the aging-washing-drying equipment were thermal decomposed until $500^{\circ}C$ at a rate of $1^{\circ}C/min$ in an air or in 4% $H_2$ gas atmosphere. The thermally decomposed C-ADU gel particles showed 24% weight loss and a more complicated profile than that of ADU gel particles.

Titanoalumino silicalite (TAS) was prepared hydrothermally, and the effects of synthesis parameters such as silica/alumina sources, $SiO_2/TiO_2$ ratio, and aging treatment were investigated. The structure, crystal size, and shape were examined by XRD and SEM, and the extent of titanium incorporation into the zeolite framework was examined using UV-vis DRS spectroscopy. For TAS preparation, aging of ca. 24h was essential, and the faster crystallization rates were achieved with Cab-O-Sil than with Ludox or TEOS as a silica source. In addition, the higher crystallinity and faster crystallization rate were obtained using sodium aluminate as an aluminum source.

The Korean Geriatrics Society was founded on October 3, 1968. Over the 50 years since then, the Society has incessantly strived to stay attuned to the aging society and to achieve an increasingly greater research impact in the field of gerontology and geriatric medicine. The Society has passed through periods of preparation for a leap forward, followed by rapid growth, expansion, and maturity. As a result, the Society has gained a firm foothold at home and abroad as a leading research society for both qualitative and quantitative achievements in geriatric medicine. At this juncture, with an ultra-aging society being just around the corner, we are celebrating its 50th anniversary and anticipating our second half-century with great enthusiasm about our mission and role as a leading geriatric research organization.

시효시 시효용액내의 첨가물의 종류에 따른 입자의 성장 거동을 관찰하였다. 첨가제로 glycerine, chloroform 및 NaCl을 첨가형 BT-oxalate 침전물의 크기와 형상에 미치는 영향을 관찰하고자 하였다. BT-oxalate 침전물은 시효시 첨가되는 불순물에 의해 입도 분포의 변화의 변화가 나타남을 확인할 수 있었다. 유기물인 glycerine, chloroform 및 금속염인 NaCl 첨가시에 첨가량이 적을 때는 불균일한 분포를 가진 입자 성장이 일어나지만 첨가량이 1mol% 이상으로 많아지면 0.4$\mu\textrm{m}$정도의 균일한 형상과 크기의 침전물이 얻어진다.

The purpose of this study is to understand how late middle-aged women in our society view and adapt to “aging”. This is a crucial step forward linking two stages, the growing young age and the declining old age, which eventually improves the qualify of life in old a9e. This qualitative study used Personal narratives extracted from tape-recorded interviews of 20 late middle-aged women in their fifties and analyzed key experiences of late middle-aged women in their transition to old age. Participants were observed to perceive not only many limitations but also alternative potentialities. First, the major challenges due to the closing young era were ‘physical declines’, including health problems and wrinkles, and ‘leaving children’. Second, the potentialities to start a new era also could be found. Many participants found themselves to be generous enough to assist others in need. In addition, they looked to adapt to new challenges. It was likely that the many adversities that they had faced made them resilient. These results show that late middle-aged women were actively negotiating with themselves and their surroundings in order to overcome their losses, maintain their potentialities, and, in the process, acknowledge their impending old age for better preparation.

본 연구는 1인 가구의 경제적 노후준비가 삶의 만족도에 미치는 영향이 미혼과 기혼에 따라 차이가 있는지 분석함으로써, 이를 바탕으로 1인 가구의 미혼과 기혼의 차별화된 정책적 대안을 마련하는데 필요한 기초자료를 제공하는 것을 목적으로 하고 있다. 분석 자료는 통계청의 2015년 사회조사 자료로 30세 이상의 1인 가구이며, 미혼, 기혼(이혼, 사별)인 4,406명을 대상으로 분석하였다. 분석 결과 첫째, 경제적 노후준비는 미혼과 기혼에 따라 통계적으로 유의미한 차이가 있었고, 기혼보다 미혼이 경제적 노후준비를 더 많이 하는 것으로 나타났다. 둘째, 삶의 만족도는 기혼에 비해 미혼의 삶의 만족도가 더 높게 나타났다. 셋째, 경제적 노후준비가 삶의 만족도에 미치는 영향에 대한 미혼과 기혼의 차이를 비교한 결과 미혼, 기혼 모두 경제적 노후준비가 삶의 만족도에 영향을 미치며 기혼의 경제적 노후준비가 삶의 만족도에 더 많은 영향을 미치는 것으로 나타났다.

In recent years, Korean population aged 65 and over has grown faster(7.2% in 2000, 14.4% projected in 2018 and 20.0% in 2026) than the other age groups and average life expectancy has increased from 65.8 years in 1980 to 75.9 years in 2000. The Aging Simulation Center(ASC) was built for people to give educational chance for further understanding of the elderly and the environment for the aged. People are able to recognize the changes including hearing loss, vision changes, and changes in the ability to touch and move after experiencing the simulated daily life of older persons. In general, ASC is composed of residential setting area and exhibition area of daily commodities for the elderly and care person. Currently, there are four ASCs in Korea. The purpose of this study is to evaluate the characteristics of space design and design elements of ASCs and to suggest design implementation for better residential environment for the elderly. For the research purpose, design characteristics such as floor plans and spatial design elements of three ASCs were analyzed and compared. As a whole, space design of three ASCs was almost same without distinguished characteristics. The major finding of this study indicates that the ASC is considerably helpful environment to understand aging. However, some of design elements such as lighting should be supplemented for safety issue. It is recommended for future design of ASC to include exterior space including outdoor stairs, paths and roads and so on. In addition, reception and preparation area should be arranged with universally designed furniture.
