Joint properties of vehicle ECU (Electric Control Unit) module which was manufactured by using Sn-Cu-Cr-Ca alloy were investigated. A new solder which has a middle melting temperature about $231^{\circ}C$ was fabricated as the type of 300um solder ball and paste type. The prototype modules were made by reflow process and measured spreadability, wettability shear strength and estimated interface reaction. The spreadability of the alloy was about 84% from the measurement of contact angle of the solder ball and the wetting force was measured 2mN. The average shear strength of the module which was manufactured by using the solder paste, was 1.9 $kg/mm^2$. Also, the thickness of IMC(intermetallic compound) was evaluated with various aging temperature and time in order to understand Cr effect on Sn-0.7Cu solder. $Cu_6Sn_5$ IMC was formed between Cu pad and the solder alloy and the average thickness of the $Cu_6Sn_5$ IMC was measured about 4um and it was about 50% of thickness of $Cu_6Sn_5$ IMC in Sn-0.7Cu. It is expected to have a positive effect on reliability of the solder joint.

As Korea has rapidly entered the aging society, the Korean government and academia are currently undergoing many researches on senior citizens. There also has been an increase in senior citizens' awareness on the importance of spatial designs that reflect the newly emerged needs brought out by their psychological and emotional changes as well as their physical aspects. Therefore, the purpose of this research is to propose a model for senior citizens' image preference to be adopted in future developments for senior-friendly spatial designs. A literature review and a questionnaire survey were implemented as research methods. The questionnaire survey was conducted at two senior welfare centers located in Seoul and Ansan and two disparate senior colleges, on the subjects of 86 senior citizens aged 60 and older. 7 styles of Romantic, Classic, Country, Modern, Natural, Casual, and Traditional were chosen for the study and the realms to apply the image preference were divided into Space, Element1 and Element2. For Space, its subcategories have been restricted to living room and bedroom while color, furniture and lighting for Element1 and material, pattern and props for Element2. Survey results were statistically analyzed for the correlation among socio-demographic factors of senior citizens, spaces and the elements. The study result showed that older age and men tended to prefer the modern style than younger age or women, and younger women preferred the romantic style. For the color preference in Element1, older men preferred the classic style while women preferred the romantic style. And, for the furniture preference, men with higher income preferred the natural style while women preferred the romantic style. For the pattern preference in Element2, younger people preferred the casual style and it showed that the housing type was the main reason for their preferences. Therefore, the image preference according to their age and gender shall be taken account of as the most important factors when designing environments for senior citizens.

Although nursing homes where physically weak seniors live must be planned as an healing environment for maintaining and improving holistic health conditions of the senior residents, many of the nursing homes in Korea are currently placed in poor environment due to lack of minimum criteria or design guideline for spatial planning. Therefore, this study aims to extract healing elements shown in nursing home design guidelines that have been developed and utilized in several developed welfare countries where aging has started before Korea. The subjects of this study were 4 international nursing homes design guidelines; and they were analyzed by the content analysis technique. As for analysis units, design guideline items were selected; and spatial composition, three dimensions of health, and healing elements for supporting the health conditions were used as analysis categories. As results, firstly, among total 259 guidelines, the guidelines that commonly applied to all the spaces turned out to be the most, then the guidelines to be applied in bathroom turned out to be the most. Secondly, in terms of holistic health, the proportion of design guideline for supporting physical health turned out to be highest followed by the one for mental health and social health. Thirdly, In terms of healing elements, items for safety, accessibility, comfort, and convenience that supported physical health and cognition that supported mental health turned out to be high. This study is expected to provide the framework for comprehensively understanding the existing design guidelines of nursing homes in the perspective of healing and to be utilized as fundamental resource for spatial planning to improve healing effects in the nursing homes in the future.

Purpose: Korea is expected to enter an aged society in 2018 and then a super-aged society in early 2025. The country's aging is progressing faster than any other country in the world. However, the foundation of the elderly friendly industry is weak, and measures at the government level are urgently needed. Especially, housing problems of the elderly are one of the most urgent measures to be taken. Korea does not have the minimum residential area standard for the elderly, and the current general minimum residential area standard is based on the survey of the housing situation without scientific evidence. Therefore, both standards need to be revised as soon as possible based on scientific evidence. Methods: The minimum residential area standard has been calculated following Karl H. E. Kroemer's Min or Max design also being called as-single cut and dual cut theory- as the maximum population value and minimum population value theory of Ernest J. McCormick. Therefore there is a need for a formula made using a few key factors, such as corresponding dimension, practical dimension, clearance, spare dimension, integrated dimension. These elements can be defined and used as formulas to calculate minimum residential area standards. Results: Assuming the results of the spatial variability in this study showed that it is possible to raise the standard of living in a terms of sustainable minimum size for the young, old and all residents. Implications: The government should set a minimum residential area standard with scientific grounds and set up a policy improving the life of people who live in an needy residential environment.
