In order to protect occupant during car crash accident, Regulation and NCAP(New Car assessment Program) have been developed among various countries like U.S.A., Europe, Korea and Australia. Especially NCAP scores affect to sales of vehicles. So vehicle makers are trying to get good score in NCAP. Low leg injuries play an important role in Australia and Euro NCAP and these injuries are related with footrest design. Optimization of footrest design in early stage of vehicle development is necessary to obtain better and robust results of low legs during crash tests. In this paper, DFSS method and finite element model were used to optimize the low leg performance in small RHD vehicles. Compared with the lower leg injury of base model, the lower leg injury of proposed model was slightly improved and robustness was enhanced also.

PWR spent fuels produced in the Republic of Korea are expected to be recycled by pyroprocess in the long term future. Even though pyroprocess waste amounts can be smaller than that of PWR spent fuel assembly in case of direct disposal, this process essentially will produce various and unique radioactive wastes. The goals of this article are to characterize these wastes, calculate the amount of wastes, design disposal systems for each waste and evaluate the radiation safety of each system by dose assessment. The absorbed dose results of the metal and ceramic waste for the engineering barrier system (EBS) showed $2.21{\times}10^{-2}$ Gy/h and $1.15{\times}10^{-2}$ Gy/h, which are lower than the recommended value of 1 Gy/h. These results confirmed that the newly proposed disposal systems have a safety margin for the radiation produced from each waste.

Purpose: This study tries to explore and analyse Service Attached Elderly Housing of Japan in order to prepare new elderly housing type effectively for aged society of Korea. Service Attached Elderly Housing was introduced in 2011 and it includes existing elderly housing of Japan such as Designated Elderly Housing, Elderly Friendly Housing and Superior Elderly Housing. Methods: Historical transition of Japanese elderly housing and background of the introduction of Service Attached Elderly Housing have been reviewed first. Thereafter research team visited to 3 elderly housings of Japan providing elderly services such as elderly care, meal, cleaning, washing, safety check, entertainment, etc. Based on the literature survey and field trip, the characteristics of Service Attached Elderly Housing have been drew out. Results: As the characteristics of Service Attached Elderly Housing of Japan, mixed use facility, community based housing, generation mix, barrier free design, and provision of daily life service for the elderly have been identified. Implications: Not only physical consideration including Universal Design but also elderly services such as elderly care, meal, housework, safety check, entertainment and so on are necessary for the supply of elderly housing.

The purpose of this paper is to analyze the handicapped facility in residential outside area, to found how to improve the law in analyzing the residential area and to suggest consideration factor in design phase. To concentrate the study, the objects of case study are selected carefully, also case study method is selected as well as objects. After observing the summary of objects, the checklist is made accordance with the improvement law of facility. The checklist has the general and detail factor about outdoor residential area, and the detail factor is based on the improvement law of facility and is used to examine and analyze.

It confirmed the facilitated diffusion of $Na^+$ of frog bladder membrane which is a tissue membrane. The mechanism was explained in $Na^+$ channel model and its referred to the $Na^+$ channel obstruction ingredient which was contained in the reference to the $Na^+$ channel obstruction ingredient and son on, e.g., seaweed, shellfish, pufferfish, phytoplankton and chinese drug. Also, it introduces the result which studied from the barrier point of the application of the tissue biosensor to the trade friction on Korea or Japan pufferfish and the marine environment in the one with high dependance. It was possible for the poison quantity of small amount pufferfish toxin (TTX), paralytic shellfish poisoning (PSP) to be measured and also to measure poison quantity in the cultivation poisonous toxin phytoplankton individual. In future, as for this tissue biosensor, it expects that it is possible to contribute widely until environment watch and also monitoring to the scene.

Purpose: To identify the perception and practices of kangaroo care in nurses and doctors working in neonatal intensive care units (NICU) in Korea. Methods: One hundred forty-nine nurses and nineteen doctors working in the NICU from six university hospitals completed a survey questionnaire. Results: Most agreed that Kangaroo care promoted attachment and parental confidence as well as physical health of the infant. However, nurses and doctors showed a negative perception in providing kangaroo care for premature infants under 1,000 grams or within several hours after birth. Major barriers for kangaroo care were worrying about extubation and safety problems of premature infants. Married or senior nurses showed a more positive perception than others. Also nurses who worked in hospitals where kangaroo care was provided had a lower barrier perception than other nurses. Conclusion: Nurses and doctors working in NICU worried about adverse effects of kangaroo care even though they perceived positive effects. Standard education programs and manuals should be developed before dissemination of kangaroo care in Korea.

In order to traffic safety during winter season, snowfall and cold area has been spread the deicing chemicals, and the spraying amount is increasing every year. Use of deicing chemicals has been and will continue to be a major part of highway snow and ice control methods. Chloride-containing chemicals such as calcium chloride or rock salt are main deicers for the road. Extensive use of chloride deicers is, however, the source of substantial cost penalties due to their corrosive action and acceleration to deterioration concrete structures. Deterioration due to de-icer salt occurs in practice in concrete pavement, dike, barrier and similar structure. This paper reports the results of effect of de-icer salt on durability of concrete structure in winter. To protect concrete structure from damage by de-icer salt in winter, the exposure test was performed using three methods such as increase in design strength upto 32MPa application of granulated blast furnace slag powder, and concrete sealer. Of these, the method of increase in design strength upto 32MPa showed better durability for deterioration by de-icer salt.

The use of tailor welded blanks (TWB) in automotive applications is increasing due to the potential of weight and cost saving. The object of this study is development of the front side member by static analysis and crash simulations. Accord-ing to the results , energy absorption and barrier force is very important parameter to control passenger safety and deforma-tion shape. A energy absorbability point of view, tailor welded blanks is most effective to absorb energy than non-twb. Non-TWB front side member and TWB applied front side member were simulated. It shows reduce stmping parts weight reduction and cost down.

Many researchers have studied for the barrier liner in the landfill that is mixed with clay mineral, native soils and solidified agent. However, they have a littel but problems for safety construction and maintenance as a bottom liner systems in the landfill. In this paper the authors studied the effects on hydraulic conductivity by electric-chemical ion-exchange agent that is a soil stabilization agent(Sulphonated Oil), The application of the soil stabilization agent to meet the hydraulic conductivity of clay liner in landfill is possible if the additive quantity and a proper reaction time is determined relevantly in the laboratory test.
