This study is about the drunken drivers' accident patterns and behavior and aims at providing basic data for developing measures to secure safety against accidents by drunken drivers and programs to cultivate good drinking habits. For this purpose, this study conducted a questionnaire of 800 persons over 20 years of age in the selected 20 companies with more than 30 employees in the 4 regions(Daegu, Masan, Changwon, and Jinhae) and analysed the 653 sheets except invalid ones among the returned 673 survey sheets in total(return rate 84.13%), and the researcher conducted a man-to-man interview with each subject from June 20th to July 31st 2006. The result are as the following. As the experience of causing an accident by drinking, the 79.1% of them had the experience, and in case of the subjects with excessive drinking over 4 times a year, the rate of the accident by drinking showed as high as 90.5%. As the patterns of accidents, in male subjects, violence(38.5%) and traffic accidents(37.1%) showed high, while in the female, hurts from falls and fall accidents(40.2%) were found be high. In case of the traffic accidents among the accidents by drinking, the rate of causing serious damage to the life was found to be 89.3%, so it showed that the traffic accidents caused by drinking were influencing on the life much. In conclusion, the drinking problem may be controlled by each individual's will, but without change of social environment and system around people, the problem can not be eradicated. Therefore there should be social infrastructure which can help people to actively live their life with exercises and hobbies, and in order to prevent the reoccurrence of a drink accident, and social structure in which there are education programs for drink accident causers and one can change the perception about drinking culture, should be formed.

Purpose and Methods: Currently, Korea has the lowest fertility rate among OECD countries. It is also true that from the aspect of encouraging childbirth policy, as the use of automobiles has increased, the interest in securing parking spaces has also become more important. However, there are efforts and researches on the supplying parking spaces for the general public in society not to the positive discrimination such as elders or pregnant women. On the other hand, there is a growing need for a dedicated parking space for pregnant women due to the changing social environment and increasing number of female drivers. At this point, proper design of the maternity parking spaces is essential. Therefore, this study is analyzing the characteristics of pregnant women such as measurements and certain actions and case studies of domestic and oversea. Through the analysis of these factors, the following results were derived. Results: First, it was determined that the important factor in the planning of the parking-block for pregnant women was the human body size of pregnant women. And the required dimensions of movement of pregnant women were derived. Second, the dimensions of automobile were analyzed and applied from the most used vehicles in the family composition. Third, after the observations, the status of the parking spaces of the pregnant women and observations showed that the drivers not only the pregnant women but others were using the spaces improperly. Fourth, at certain conditions of the parking spaces, in order to improve the efficiency of the parking spaces, it is necessarily considered that the usage of designated accessible parking spaces can be used together by not only the disabled but also to the passengers who are classified as 'transportation weak' such as pregnant women. Implications: In this study, the researcher will propose the shape and size of the parking-block for pregnant women considering the elements derived above.

OBJECTIVES : Fixed roadside objects are a threat to drivers when their vehicles deviate from the road. Therefore, such roadside objects need to be suitably dealt with to decrease accidents. This study determines the factors affecting the severity of accidents because of fixed roadside objects. METHODS : This study analyzed the crash severity impact of fixed roadside objects by using ordered probit regression as the analysis methodology. In this research, data from 896 traffic accidents reported in the last three years were used. These accidents consisted of sole-car accidents, fixed roadside object accidents, and lane-departure accidents on the national highway of Korea. The accident severity was classified as light injury, severe injury, and death. The factors relating to the road and the driver were collected as independent variables. RESULTS : The result of the analysis showed that the variables of the crash severity impact are the collision location (left side), gender of the driver (female), alcohol use, collision facility (roadside trees, traffic signals, telephone poles), and type of road (rural segments). Additionally, the collision location (left side), gender of the driver (female), alcohol use, collision facility (street trees, traffic signals, telephone poles), and type of road (rural segments), in order of influence, were found to be the factors affecting the crash severity in accidents due to fixed roadside objects. CONCLUSIONS : An alternative solution is urgently required to reduce the crash severity in accidents due to fixed roadside objects. Such a solution can consider the appropriate places to install breakaway devices and energy-absorbing systems.

This study was performed to investigate LBP(low-back pain) prevalence rate and its related factors inphysical therapists. A self-administered questionnaire survey was conducted to 522 physical therapists in Daegu and Gyeongsangbuk. The LBP prevalence rate for recent 6 months was $61.7\%$. According to age, the prevalence rate was highest in the group aged 24 or less for both male and female physical therapistis. For male physical therapists , it was higher in smokers and drivers, but for female ones, it was not in a significant relationship with smoking and driving. According to work experience, the prevalence rates of those who had been working for less than one year were the highest, and those who had been working at hospitals and clinics were $69.1\%$, significantly high. According to therapy techinque, the prevalence rate related ti PNF was $71.6\%$, the highest and to occupational therapy was $34.3\%$, the lowest. According to working environment for six months, in both male and female physical therapists. LBP prevalence rate was in a statistically significant relationship with work hours during the day, night and weekend duties, repetitive works, motions that bend or twist the waist, the number of patients per day, the number of time to help patients per day, the number of time to carry medical equipment per day and the length of time to work standing. The rate was also higher when physical therapists fekt nire stress from their work. According to the result of multiple logistic regression analysis, male was in a significant relationship with work experience and motions that bend or twist the waist and female was in a significant relationship with work hours during the night and weekend duties, the number of time to help patients per day, motions that bena or twist the waist, actions taken to protect the waist. As for the developmental pattem of LBP in the group of physical therapists with LBP for six moths, $15.7\%$ of them had LBP for first time, $42.3\%$ had recurred LBP, and $42.0\%$ had chronic LBP. As for the causes of LBP, $51.7\%$ said that it was because they worked in the same posture for a long time, and as for how to treat LBP, 48.8% said that they treated themselvs or got help from their co-wokers. The results presented above suggest that physical therapists are exposed to high risk of LBP caused form occupational activities. Therefire, it is necessary to improve working environment to reduce the occurrence of LBP and to develop education programs for preventing the occurrence and recurrence of LBP.

This research aims to shed light on the technology adoption process and its drivers in the Vietnamese educational system. Research data was collected with an online questionnaire from more than 600 teachers in primary schools, secondary schools, high schools, colleges, and universities in Vietnam in 2020. Based on a holistic literature review, we develop a model of two extrinsic factors (global needs and school-infrastructure), and two intrinsic factors (teachers' technological literacy and their beliefs), which are correlated with the teachers' technological adoption. We measure the dependent variable by asking the teachers' ability and their efficacy to implement technology in teaching according to a Likert scale. With the support of SPSS_22 and STATA_2015, we find that over 70% of changes in technology adoption are explained by the changes in four independent variables and three control variables related to age, gender, and teaching-level of the teachers. Furthermore, these independent variables are significantly and positively associated with two dependent variables. However, a significant difference in technology integration ability can be seen among teachers' gender, age, and school-level. Specifically, male teachers seem to adopt technology at schools than female teachers better, and university teachers have the lowest level of technology adoption compared to other school-level teachers.
