Traffic accident by aging drivers is expected to be on the rise rapidly as the number of aging drivers is rising along with the aging trend being progressed. In this study, traffic accident features depending on the classification of aging population and non aging one was evaluated. As a result of this evaluation, effect factors influencing over the aging population was found to be expressed differently from that of the non aging one. Odds ratio between the aging population and non aging one was evaluated through logit model and a model with potential accident probability of the aged drivers was developed. Accident risk of the aged drivers under the condition of curved road, cutting section and moistured road was revealed to be higher than that of the non aging population.

Purpose: Aging process comes with cognitive impairment due to decreased neuronal cell number, activity, and neuronal circuit. Alteration of inhibitory neurons contributes to cognitive impairment in normal aging and is responsible for disrupting the excitation/inhibition balance by reducing the synthesis of gamma-aminobutyric acid (GABA). Morus nigra (Mulberry) is a natural physiologically active substance that has been proven to have anti-oxidant, anti-diabetic, and anti-inflammatory effects through many studies. This study aimed to evaluate the effects of the mulberry extract (ME) on cognitive function through anti-oxidant enzyme and GABAergic neuronal activity in aged rat brain. Methods: Sprague Dawley rats were randomly assigned as the young group (8 weeks, n= 8), aging group (67 weeks, n= 8), and aging+ mulberry extract group (67 weeks, n= 8). The aging+ mulberry extract group was orally administered 500 mg/kg/d mulberry extract for 6 weeks. Results: The aging+ mulberry extract group improved spatial and short-term memory. The antioxidant potential of ME increased the expression of superoxide dismutase-1 (SOD-1) and decreased inducible nitric oxide synthase (iNOS). Also, the aging+ mulberry extract group significantly increased the expression of GABAergic interneuron in hippocampus cornu ammonis1 (CA1) compared to the aging group. Conclusion: The number of GABAergic inhibitory interneurons was deceased and memory functions in the aging process, but those symptoms were improved and restored by mulberry extract administration.

The purpose of this study is to investigate the planning of the community spaces for sustainable apartment complex under the aging society. For this, it is needed to identify the practical meaning of community spaces for elderly residents. In many cases, existing apartments' community spaces have been designed without considering the elderly. In order to develop successful environment for aging society, it is necessary for us to precisely review how elderly residents are changing their needs. Survey and depth-interview methods were used for data collection of this study. This study was performed in the five subject apartments located in Haeundae new town, Busan. In planning of community spaces for sustainable apartment complex in the aging society, 1) The population of the elderly in apartment complex has been increased with progress of the aging society, and it has been necessary to enlarge and consider the aging-friendly community space. 2) When the community space is located in a good accessibility, visual openness, multipurpose composition and the center of complex, it was investigated that the degree of its usage was high. 3) Common apartment complex for the elderly was deficient, and the composition and the layout of community spaces were needed, which included sports facility, spaces for leisure culture and study. This study could be utilized as basic data for designing community spaces in apartments from the perspective of sustainable community.

Objective:This study aims to devise industrial injury prevention measures by analyzing industrial injury characteristics including the status of industrial injuries, source of industrial injury and accident type in order to prevent aging workers' industrial injuries that account for more than half in the workplaces in agriculture. Background: Continuous migration from farm to city takes place among young people in rural areas in Korea, a traditionally agricultural country due to rapid industrialization and economic development. The aging rate in rural areas in 2013 was 37.3%, about three times higher than the total aging rate of 12.2% in Korea. According to industrial injury statistics of the Ministry of Employment and Labor, the number of industrial injuries in agriculture shows an uptrend and the industrial injuries of aging workers account for more than 50% each year. Method: Of the 2,970 industrial injury cases occurred in the workplaces in agriculture for five years during 2008 and 2012 offered by a national agency related to health and safety, this study analyzed 1,767 industrial injury cases of aging workers. Results: As a result of an analysis on aging workers' industrial injuries by company size in agriculture, 89.8% of the total number of industrial injuries were analyzed to occur in small scale company. According to aging workers' industrial injuries by source of industrial injury and accident type, the outdoor floor and a fall were analyzed to be the highest at 16.5% and 26.1%, respectively. Conclusion: This study analyzed aging workers' industrial injuries by company size, age, job duration, accident severity, gender, nationality, the source of industrial injury and accident type in order to identify industrial injury characteristics in agriculture. Application: The identification of industrial injury characteristics of aging workers in agriculture is judged to be helpful to devising effective measures to prevent industrial injuries.

This study was designed to analyze the results of Vaso-Aging Degree in Oriental medical examination. The subjects were workers in the automobile manufacturing industry. The subjects consisted of 24,077 industrial workers who had received Oriental medical examination by Oriental medicine and they submitted questionnaires about drinking history and smoking history, during 9 months from March to November. They were categorized by job class, drinking history and smoking history, exercising history. The percentage of Vaso-Aging Degree were measured by using SA3000P(Medicore, Seoul, Korea). We analyzed the relationship between job class, drinking history, smoking history, exercising history and Vaso-Aging Degree using ${\chi}2$-test of the SPSS Ver. 14.0. In job class, Sales personnel were apt to have a higher level of Vaso-Aging Degree than Office workers. And getting older workers are, the higher Vaso-Aging Degree becomes. Vaso-Aging Degree of the Drinker group showed a higher level than the Non-Drinker group. Vaso-Aging Degree of Smoker group were higher than the Non-smoker group. On the other hand, Vafo-Aging Degree of Non-Exerciser group were higher than the Exerciser group. They have to manage Vaso-Aging Degree closely and educate the workers to quit smoking and drinking for their health promotion. Furthermore, continuous health check up needs to be done connectedly.

The present review has mainly focused on the specific parameters including aging (aging days, temperature, relative humidity, and air flow), eating quality (flavor, tenderness and juiciness), microbiological quality and economic (shrinkage, retail yields and cost) involved beef dry aging process. Dry aging is the process where beef carcasses or primal cuts are hanged and aged for 28 to 55 d under controlling environment conditions in a refrigerated room with $0^{\circ}$ to $4^{\circ}C$ and with relative humidity of 75 to 80 %. However there are various opinions on dry aging procedures and purveyors of such products are passionate about their programs. Recently, there has been an increased interest in dry aging process by a wider array of purveyors and retailers in the many countries. Dry aging process is very costly because of high aging shrinkage (6 to 15 %), trims loss (3 to 24 %), risk of contamination and the requirement of highest grades meat with. The packaging in highly moisture-permeable bag may positively impact on safety, quality and shelf stability of dry aged beef. The key effect of dry aging is the concentration of the flavor that can only be described as "dry-aged beef". But the contribution of flavor compounds of proteolysis and lipolysis to the cooked dry aged beef flavor is not fully known. Also there are limited scientific studies of aging parameters on the quality and palatability of dry aged beef.

This study investigates the utilization of an electric-field-induced super cooling system in long-term dry aging of beef loin. Analyzed quality properties of dry-aged beef loin applied with electric field refrigeration (EFR) versus commercial refrigeration (CR). Quality properties was including aging loss, pH, water holding capacity (WHC), cooking loss, color, warner-bractzler shear force (WBSF), total plate count (TPC), and thiobarbituric acid reactive substances (TBARS). Aging loss of wk 1 EFR was significantly lower than CR (p<0.05). pH of EFR was slow change tendency compared CR. WHC of both aging methods were higher with increase in aging duration. Cooking loss of wk 1, 2, 4, and 10 EFR were significantly lower than CR (p<0.05). Lightness and redness of EFR was slow change tendency compared CR. However, yellowness of EFR was increased until wk 2, 3, and significantly decreased at wk 10 (p<0.05), but yellowness of CR was decreased until wk 3 and significantly increased with an increasing aging weeks (p<0.05). Both aging methods of WBSF was decreased with increase in aging weeks; however, wk 10 of CR was significantly lower than EFR (p<0.05). TPC after wk 3 EFR groups were significantly lower than CR groups (p<0.05), and TBARS of EFR groups were significantly lower than CR (p<0.05). The present results show that application of the EFR system for dry aging beef loin can extends its shelf life and induce changes of several aging properties in similar to commercial aging.

Purpose: The purpose of this study was to examine the effects of an aging management program on the resilience and successful aging of middle-aged women. Methods: A quasi-experimental study with a non-equivalent control and pre-post test design was used. The participants were 39 middle-aged women living in urban areas in Korea. The experimental group (n=22) received the aging management program for a total of 10 weeks, 90 minutes to 120 minutes per week. The aging management program consisted of strategies to enhance the behavior, promotion conditions, and habits of the program, including various activities for middle-aged women. The data were analyzed using χ² tests, independent t-tests, and repeated measures analysis of variance with the SPSS/WIN 21.0 program. Results: The resilience score of the experimental group was significantly higher level than the score of the control group in the time-to-group interactions (F=3.70, p=0.029). The successful aging score of the experimental group was significantly higher than the score of the control group in the time-to-group interactions (F=5.86, p=0.004). However, the sub-hypotheses of resilience (self-regulation and interpersonal relationships) and successful aging (physical aging adaptation and psychological age adaptation) were partially accepted. Conclusions: The aging management program for middle-aged women was identified as an effective intervention for promoting resilience and successful aging in middle-aged women. Therefore, this suggests that the aging care program could be a useful intervention program to improve the mental health of middle-aged women living in communities.
