Purpose: To identify the risk factors for suicidal ideation across the life cycle among Korean adults using data from 2015 Korean Psycho-social Anxiety Survey. Methods: The data were statistically analyzed using hierarchical logistic regression analysis. Results: The factors associated with suicidal ideation among the young adult group were education level (odds ratio [OR] 1.62, 95% confidence interval [CI] 1.05~2.49), self-esteem (OR 1.19, 95% CI 1.12~1.27), stress (OR 3.26, 95% CI 2.07~5.15), anger control problems (OR 3.58, 95% CI 2.34~5.50), and depression (OR 2.59, 95% CI 1.66~4.04) whereas among the middle-aged adults the factors were education level (OR 1.58, 95% CI 1.12~2.23), existence of a spouse (OR 2.55, 95% CI 1.72~3.78), self-esteem (OR 1.13, 95% CI 1.08~1.18), stress (OR 2.46, 95% CI 1.81~3.33), anger control problems (OR 1.70, 95% CI 1.22~2.36), and depression (OR 2.64, 95% CI 1.91~3.64). Among the older adult group the findings were the existence of a spouse (OR 2.16, 95% CI 1.37~3.39), self-esteem (OR 1.22, 95% CI 1.13~1.32), stress (OR 2.21, 95% CI 1.38~3.54), anxiety (OR 2.42, 95% CI 1.46~4.02), and depression (OR 2.48, 95% CI 1.30~4.72). Conclusion: The findings suggest that there may be a need for different suicide intervention programs to decrease suicidal ideation across the life cycle.

This paper analyzes a social insurance system that integrates unemployment insurance with a pension program, allowing workers to borrow against their future wage income to finance consumption during an unemployment episode and thus improving their search incentives while reducing risks. This paper identifies the conditions under which the integration improves welfare and the factors which determine the optimal degree of integration. A fully integrated system is one in which no reliance is placed at all on a separate tax-funded unemployment insurance program. We show that when the duration of unemployment is very short compared to the period of employment or retirement, the optimal system involves an exclusive reliance on pension-funded self-insurance. This system imposes a negligible risk burden for workers while avoiding attenuating search incentives. We also argue that a joint integration of several social insurance programs with a pension program through an individual account is desirable unless the risks are perfectly correlated to each other.

This study was conducted to determine family factors related to obesity of high school students. A descriptive correlational study was conducted with 384 high school students in I metropolitan city. Data were collected from February to April of 2015 using self-report structured questionnaires. Questionnaires included weight, height, individual characteristics of subjects and their familial characteristics. Collected data were analyzed by multiple logistic regression. Logistic regression analysis revealed that male gender (aOR = 4.37; 95% CI [1.26, 15.16]), having a non-regular paternal job (aOR = 3.10; 95% CI [1.15, 8.40]), and not being in a two parent family (aOR = 3.52; 95% CI [1.29, 9.61]) were statistically significant contributors to obesity. These results indicate that it is necessary to improve social awareness regarding the obesity risk of male adolescents. Health care providers should recognize the importance of family factors such as parental socioeconomic status and family structures.

Vehicles have recently become one of the main factors affecting our quality of life, and the needs of vehicles are still increasing. As a result, the growth of vehicles generate more crashes every year. One main factor for vehicle crashes is uncareful driving behaviors. Especially, drowsy or fatigue driving behaviors explain about 10-20% of the crashes, and they cause serious results because of the delay of response time and the decrease of object-recognition. Therefore, this research conducted real time image processing tests in order to study how cellular phone usages and drowy(or fatigue) drives affect driving behaviors. A vehicle simulator was used for this research, and the faceLAB 4.5 of Seeing Machines for eye image tracking tests using a small camera was installed in the front of the simulator, and normal and drowsy(or fatigue) driving patterns were analyzed.

This study researched methods for coping with safety accidents by university students, after considering the situation of safety education by universities in Korea. For this study, a survey of 411 students of universities in the cities of Gwangju and Daejeon was conducted. According to the results, the ratio was high for answers such as willingness to participate in safety education beginning with the departments of engineering, art and physical training, education, art and humanity, social sciences and natural sciences, and medical sciences. It was found that university students most preferred first aid among the contents of safety education. University students of all departments answered that they had experienced safety education, but were afraid to be embarrassed in the case of actual safety accidents, as was found through the results of investigations of their awareness of coping methods with safety accidents. It was verified that many times their suffered skin and other wound in an earlier safety accident that they had experienced. This study suggests that safety education needs to be accomplished in the university curriculum, predicting and practicing for causes and factors of danger in advance, in order to improve the level of safety awareness and safety competence among university students.

This study examined the determinants of housing affordability using the 2014 fact-finding survey of housing. This study identified the effects of characters of districts as well as the effects of characters of family and housing, taking advantage of HGLM(Hierarchical General Linear Model). The results of this study showed that male householder, higher education level, the monthly housing, higher satisfaction of environment of housing are the factors that increased the odds of living at unaffordable housing, but higher income, public transfer recipient, living at sub-standard housing, the Jensei housing are the factors that decreased the odds of living at unaffordable housing. And the higher housing price, the higher rent of the districts increased significantly the odds of living at unaffordable housing, but the higher rate of public housing of the districts decreased the odds of living at unaffordable housing. This study provides the basis that the price of housing and rent should be controled and the policy of public housing should be expanded for housing welfare.

The rapid expansion of the software industry has brought a serious security threat and vulnerability. Many softwares are constantly attacked by exploit codes using security vulnerabilities. Smart fuzzing is automated method to find software vulnerabilities. However, Many resources are consumed in fuzzing, because the fuzzing needs to create data model for target software and to analyze a data file and software binary. Therefore, The automated method for efficient smart fuzzing is needed to develop the automated data model. In this paper, through analysing the input file format and optimizing the data structure, we propose an efficient data modeling framework for smart fuzzing and implement the framework for detect software vulnerabilities.

The Korean government required the mandatory ratio of public housing including the housing unit for elderly in February 2012 and the number of them is expected to increase accordingly. To prepare for an aged society, these enabling ubiquitous technology will be able to support efficient health care services, which was mentioned in various studies. Therefore, the aim of this study is to draw the design elements for an apartment for providing health care services according to the degree of independence of elderly people and to grasp the current situation and work out tactics by the evaluation of four actual cases. In housing unit in the elderly housing project, design elements supporting amenity improvement was rated to the highest importance, however, in reality, was reflected at lower rate while the risk management plan for public space was applied at the highest rate. Design elements required by new technology such as health monitoring and community management with outside world are still not reflected, however, in order to realize the concept of 'aging in place', health care services in various aspects should be considered in housing planning.

With the growing concern over frequent occurrences of criminal events, help-requesting mobile applications have drawn attention. However, existing applications solely focus on providing help-requesting services. Therefore, in this paper, we design and implement a help request and response process which allows users to request help by sending messages and locating their friends, acquaintances and even near-by application users, and to allow help be reached by forwarding messages. This application is composed of three parts: help-requesting, help-responding, and checking-status. This application is developed on the Android platform where we exchange users' longitude and latitude through web server communication. We conducted test to verify the effectiveness of the forwarding function, and it has been confirmed that 93.33% of subjects used the forwarding function to help users at risk.
