Domestic insurance claims were statistically investigated to analyze the elderly driver's accident patterns and injury types in side impact crashes. Medical treatment records and accident vehicle damage photos have been surveyed for 5,419 cases. The results of our statistical analysis showed that the thorax injury risk of the elderly drive group is 8.8 and 4.0 times higher than that of the young and middle age group respectively. Diagnosis showed that most thorax injuries were caused by rib fracture. The head injury risk of the elderly female driver group seemed to be higher than that of the younger female driver group, however, statistical test has not been conducted because of the lack of number of samples for elderly female accident.

The purpose of this study was to analyze the effects of ankle flexibility, gender, and Q-angle on the ankle joint injury factors during one leg drop landing. For this study, 16 males(age: 20.19±1.78 years, mass: 69.54±10.12 kg, height: 173.22±4.43 cm) and 16 females(age: 21.05±1.53 years, mass: 61.75±6.97 kg, height: 159.34±4.56 cm) in their 20's majoring in physical education using the right foot as their dominant feet were selected as subjects. First, an independent t-test of joint motion and joint moment according to the experience of ankle injury was conducted to determine the effect of physical characteristics on ankle joint injury during one leg drop landing(α = .05). Second, the variable that showed a significant difference through t-test was set as the dependent variable, and the ankle flexibility, gender difference, and Q-angle were designated as independent variables to use Multiple Linear Regression(α =. 05). As a result of this study, it was found that the group that experienced an ankle joint injury was found to use a landing strategy and technique through adduction of the ankle joint and internal rotation of the knee joint, unlike the group without an injury. It was also confirmed that this movement increases the extension moment of the ankle joint and decreases the extension moment of the hip joint. In particular, it was found that the dorsi flexion flexibility of the ankle affects the ankle and knee landing strategy, and the gender difference affects the ankle extension moment. Therefore, it was confirmed that physical characteristics factors affecting ankle joint injuries during one leg drop landing.

This study was aimed at investigating the activities of a badminton club and designing smart wear to prevent sports injuries during badminton club activities. Everyone is familiar with sports in an aging society and clubs are gradually developing. Popular badminton club activities lead to frequent sports injuries, especially ankle injuries, which are a serious problem that hampers members' participation in sports. Therefore, this study aims to propose a prototype design for smart wear to prevent sports injuries, including ankle injuries. First, we identified the characteristics and considerations of members of badminton clubs, and the components of smart wear to prevent sports injuries. Second, members of the badminton clubs and an elite badminton player participated in a survey on the issues and requirements associated with wearing smart wear. Third, usage scenarios for smart wear were created based on literature reviews and the user assessment lists. Fourth, a prototype of the smart wear to prevent sports injuries including ankle injuries was created based on the scenarios. With the proposed smart wear, members of badminton clubs who may require assistance with sports injuries will be able to monitor said injuries, as well as their health condition, as avatars in visual games through a smart terminal. The visual game system will provide easier access to information about sports injuries and health. This smart sportswear will allow members of badminton clubs to prevent sports injuries and review their performance. This study can be utilized to design smart wear to prevent sports injuries and monitor sporting activities or bio-signals.

One of the most important factors that affect a person's risk of injury in a motor vehicle crash is the age of the person. This study investigates the characteristics of crash injuries among young, middle-aged and older drivers and occupants. Based on the comprehensive claim data from automobile insurance from 2000 to 2007, this study examines in great detail the drivers and occupants injury body regions and severity by age in car-to-car frontal crashes. It has been shown that elderly drivers and occupants suffer more injuries at a chest region compared to the middle-aged group. This research calls attention to the need for design to make vehicles more protective for older drivers in car-to car frontal crashes.

Real-world accident cases were investigated to understand injury characteristics of the elderly driver. A total 10 cases of car-to-car frontal crash accidents from passenger car including SUV claimed to domestic car insurance company were reviewed. The injury characteristics of the elderly were analyzed from personal information (gender, age), medical treatment record (medical certificate, curative days), vehicle information (model, air-bag, seatbelt) and damage information. This study showed that elderly driver has higher possibility of thorax injury than non-elderly's. Moreover, Injury type and severity were more severe than non-elderly driver at similar type accident conditions. Also, elderly driver's medical treatment period needs 3 times more than non-elderly driver's.

Most bacteria form biofilm as self-defence system, making efficient food sanitization, preservation, and instrument washing more difficult. Biofilm formation of Salmonella, E. coli, B. cereus, and S. aureus was observed during 24 hr food preservations by performing microtiter plate and glass wool assays. Most cells formed biofilm and attached onto glass wool. When biofilm formation and injury were analyzed on the microtiter plate, 10 and 20% acid-injured E. coli and S. aureus, respectively, 30-50% cold temperature $(4^{\circ}C)-injured$ B. cereus and E. coli, and 30-55% 6% sodium chloride solution-injured Salmonella showed significant biofilm formation. Results indicate biofilm formation level differed within species depending on type of stress.

Gelatinization characteristics of pigmented rice varieties were determined in terms of amylose contents, amylograph, gel consistency, water absorption index (WAI) and water soluble index (WSI). Amylose contents of black and red rice were lower than those of brown rice, especially Sanghaehyanghyulla exhibited the lowest amylose contents among the pigmented rice varieties tested. There was no significant difference in WAI among the pigmented rice varieties, but WSI was lower in red rice than the others. Peak viscosity of black rice measured in a Brabender amylograph was lower than those of red and brown rice.
