Zinc ion has both essential and toxic effects on mammalian cells. The results demonstrated that the ability of zinc to act as an inducer of apoptosis in C6 glial cells. Incubation with 0.2 mM ZnCl₂ caused cell death that was characterized as apoptosis by internucleosomal DNA fragmentation, formation of apoptotic bodies, nuclear fragmentation and breakdown of the mitochondrial membrane potential. ZnCl₂-induced apoptosis of C6 glial cells was prevented by the addition of Sibjeondaebo-Tang and antioxidants including reduced glutathione, N-acetyl-L-cysteine. We further confirmed that ZnCl₂ decreased the intracellular levels of GSH as well as generation of H₂O₂ in C6 glial cells. In 2D-electrophoresis, computer-assisted comparative analysis of the respective silver stained spot patterns revealed 3 groups with strongly decreased intensity by ZnCl₂. Whereas, 3 groups with increasing intensity were recovered by Sibjeondaebo-Tang. These results suggest that Sibjeondaebo-Tang may function as an antioxidant against free radicals and be applicable to the treatment of brain cells against oxidative stress.

As part of alternative of elderly problems in the future super-aging society, this study aims to extract an improvement plan of interior environment design of Seoul-type day care centers to expand in future by observing day care centers as medical and healing environments, from the perspective of user experience. For this study, after selecting major activity areas of representative cases of Seoul-type day care centers, user behaviors in the space were observed and 4 seniors of baby-boom generation who are potential uses were chosen as personas by reflecting characteristics of healthy elderly, physical aging, mental aging and infirm elderly, from the perspective of user experience. Based on previous studies on healing environments, these characteristics and demands of personas were classified into environmental aspects, physical aspects and mental aspects to extract an improvement plan. The study results are as follows. First, interior environment design reflecting persona characteristics helps the elderly adapt to the environment and provides a comfortable environment like home for stability, treatment and recovery of memory. Second, interior environment design reflecting persona characteristics helps psychological healing through light entering the large windows and natural environment elements. Third, for interior environment design reflecting persona characteristics, finish materials with bright and soft colors should be used to change the images of facilities positively. Fourth, spatial composition should be remedied through division of space and built-in furniture depending on the needs of users for loitering of extra time and programs.

Nowadays the numbers of the aging population are rapidly increasing in Korea, which became the 'aged country' from the year 2000. These aged people are getting more important consumer group and the products and services related to the silver industry are getting bigger. Universal fashion design is based on the concept of universal design that pursues the 'design for all'. This study aims to understand the physical, physiological, and psychological characteristics of the elderly women and apply the principles of universal design to universal fashion design for the elderly. Korean traditional vest, 'Baeja' was used as the design inference for the target of age 55 and older. This group is also called as 2Y2R(too young to retire), Tonk(too only no kids), Y-O(young-old) generation, or OPAL(old people with active life). Principles of universal design such as accessibility, flexibility in use, fair in use, aesthetics, safely-oriented were applied in developing the vest. This universal fashion products enable the elderly to have physical independence and make them have the self respect and better life.

As the population of senior citizens has been increasing very rapidly, the importance of their education is gradually emphasized. To maintain their mental and physical health, the solution on the biological, physical, and educational approach might be helpful and effective. Especially in the aspect of the educational approach, the mathematics education can be regarded as an important subject for keeping the seniors in a good mental health. The reason is that the ultimate goal of mathematics education is to pursue an enhancement of mathematical thinking ability. By the reason, this study aimed to develop mathematical materials for enhancing seniors' thinking ability, and the seniors usually belong to fifties and sixties. To this purpose, this study selected the six essential mathematical thinking elements and four mathematical domains of 'number and operation', 'shape and measurement', 'possibility', and 'patterns'. Based on these elements, the mathematical materials including the nine types of activities using games and commercial manipulatives were developed. On the subject of 52 female seniors, the instruction was conducted using a part of the materials during 100 minutes. Also, 13 survey items were developed beforehand, and the survey was implemented after the class, and eventually 48 seniors responded in the survey. As a result, it is meaningful to develop the materials not only for enhancing mathematical thinking ability but for understanding and utilizing the content of materials. Furthermore, it is requested that those materials be differentiated according to the degree or the difference of age, academic ability, and sex.

Alkaline water electrolysis system is the oldest technology among various hydrogen production processes to produce green hydrogen with the least amount of greenhouse gas generated. Alkaline water electrolysis (AWE) system is used in alkaline atmosphere condition. In comparison to polymer electrolyte membrane water electrolysis (PEMWE), this system can utilize stable transition metals such as nickel, cobalt, and silver, as electrode catalysts. AWE is relatively inexpensive, and can easily be scaled up to large scale. The system is a mature technology, as it has been in operation since the beginning of the 20th century in MW-scale for hydrogen generation, and there are currently more than 20 commercial manufacturers. In this review, the basic principles of AWE, along with catalysts, electrodes, and diaphragm membranes, are summarized. Particularly, the research and development trends of the diaphragm membrane unit, which is the core component of an AWE, are discussed in detail.
