This study conducted a content analysis of infertility studies that have been done in South Korea with the purpose of finding the characteristics and trends of the existing studies. A total of 100 academic journals and master’s and doctoral theses published from 1988 to February 2020 was reviewed in terms of the basics, subject, topic, and method of the study. It is found that infertility studies have been consistently conducted and rapidly increased since 2010. The largest number of infertility studies was published in the field of nursing and a majority of the study subjects were infertile women who accounted for 88% of those studied. The topics were mostly related to psychology and adaptability, and 64% of the total studies examined used quantitative approach as their primary method of study. The analytic results of this study have been interpreted and discussed in terms of the policy implications that they imply in South Korea and the potential direction for future studies on infertility and infertility counseling.
This study aims to identify the impact of gender equality and work-family balance on attitude toward the necessity of having children. The survey data were collected from 800 adults aged 19 years and older living in the D region of Busan, Korea, and analyzed using SPSS 25.0 statistical package for descriptive statistics, independent sample t-test and multiple regression. The results showed that a high perception of gender equality was significantly associated with a positive attitude toward the necessity of having children.
However, those experiencing more difficulties with work-family balance felt more burden of child rearing and had a negative perception toward the necessity of having children. On the other hand, the perception of utilizing work-family balance policy did not have a significant effect on the necessity of having children.
Based on these findings, this study suggested the importance of work-family balance based on the perception of gender equality as a way to overcome the low fertility and provided implications for population and family welfare policies.
The purpose of this study was to investigate how depression and the presence of meaning in life affect warning symptoms of relapse in alcoholics. The data were collected from 270 alcoholic inpatients who were treated in an alcohol hospital located in a metropolitan city of South Korea over three months between November 2019 and January 2020 and analyzed by descriptive statistical analysis, t-test, ANOVA, Pearson correlation coefficient, hierarchical regression and structural equation. Bootstrapping was performed to confirm the significance of indirect effects of mediating parameters. The results of this study showed significant correlations among depression, the presence of meaning in life, and warning symptoms of relapse in alcoholics. The presence of meaning in life showed a significantly negative correlation with depression and warning symptoms of relapse in alcoholics, and partially mediated the relationship between depression and warning of relapse in alcoholics. The findings suggested further research studies to prevent relapse in alcoholics.
The accident rate for aircraft is very low compared to other transportation modes, but in the event of an accident during the flight, there is a high risk of falling. In addition, it is very difficult to prove the cause of the accident because it consists of many parts. Therefore, aviation accident investigation should be objective and fair in order to identify risk factors, evaluate risk levels, and offer a safety message to those involved in the accidents. The organization of aviation accident investigation sought independence from an international perspective to enhance its professionalism in terms of organization and function for aviation safety. Therefore, the Presidential Committee for National Aviation and Railway Safety needs to be established to strengthen the independence of the Aviation and Railway Accident Investigation Board in South Korea so that it can perform independent investigation in terms of composition and function, such as budget, personnel, and so on.
The purpose of this study is to empirically analyze the effects of job security, organizational culture, and conflict factors on job satisfaction and organizational commitment of re-enlisted officers in the army of Republic of Korea. The findings of this study are as follows. First, most of the re-enlisted officers had a high job security. Second, their job satisfaction and organizational commitment levels were high on average.
Third, the positional stability of older-aged group was found to be lower. Fourth, according to the types of re-enlisted officers, the average score of organizational culture was higher for re-employed officers than reappointed officers, which is due to the difference of selection system. Lastly, multiple regression analysis showed that job security did not have a significant effect on job satisfaction or organizational commitment, On the other hand, organizational culture and interpersonal conflict affect organizational commitment, and job satisfaction was confirmed to act as a partial medium.
In this study, a laboratory burning experiment was conducted to examine the combustion characteristics of Pinus densiflora surface fuel by different slope conditions such as 0°, 10°, 20°, 30° We observed the changes in forest fire behavior after fuel-bed ignition. According to the results of this study, the rate of fire spread increased as the slope angle increased; it was 14 times faster at slope angle of 30° than at 0° The fire intensity also increased as the slope angle increased, ranging from 246.73 kW/m to 2,602.96 kW/m. The flame height and tilt decreased but the length of flame increased, when the slope angle increased.
The total combustion rate also decreased as the slope angle increased. Since the moisture content of canopy fuel was measured higher with the increase of the crown base height under the same slope conditions, the risk of forest fire ignition was found to be low. The findings can be used as a basic data for understanding of fire behavior by slope condition.
The objective of this study is to estimate the effects of forest management activities on mortality rates and fuel characteristics of coarse woody debris for Pinus densiflora stands in South Korea. This study used 40 managed plots and 14 unmanaged plots from the 6th National Forest Inventory plots. The results indicated that mortality rates of the managed stands were about 1.6% while those of the unmanaged stands were about 5.3%. The amount of coarse woody debris affecting forest fire spread was 2.2TOE ha-1 for the unmanaged stands, while 1.6TOE ha-1 for the managed stands. According to the results of decay class analysis, the ratio of decay class I, the most vulnerable to forest fires, was 22% for the managed stands while 29% for the unmanaged stands. Therefore, the unmanaged pine stands had higher fuel loads for forest fire in terms of coarse woody debris and higher decay rates than the managed Pinus densiflora stands. This information could be very useful to understand forest fire fuels in coarse woody debris for Pinus densiflora stands in South Korea.
This study evaluated the instream flow of the existing dams and major water-level stations in the Imjingang river basin by the operation of Hwanggang Dam in North Korea and proposed a solution for securing instream flows. First, stream flow, basin inflow, and dam releases were reasonably estimated by water balance analysis using daily averaged data in the Imjingang river basin. Second, streamflows at major water-level stations in the Imjingang river basin decreased significantly after the Hwaggang dam operation, which confirmed that the Hwanggang Dam in North Korea had a significant effect on the streamflows of the Imjingang river basin in South Korea. Third, the instream flow analysis for the Imjingang river basin confirmed that instream flows were not consistently satisfied in all water-level stations. Finally, the Hwanggang Dam operation was one of the main reasons for the lack of instream flow, since the total amount and period of shortage increased up to 14,156% and 16,800%, respectively after the Hwanggan dam operation. We then suggested how to utilize the existing dams and shared river basins to secure instream flow. In the future, various long-term and well-planned strategies would be needed.
This study empirically examines the vulnerability of the community and the perception of the women’s safety culture in order to realize a community that is safe from disaster. The purpose of this paper is to analyze empirically the women’s perception on safety culture and community vulnerability to disasters.
The analytical results are as follows. First, according to the safety awareness scores, women tended to have higher risk perception than men. Second, the safety awareness scores by disaster type indicated that their risk perception was highest for man-made disasters. Third, disaster vulnerabilities were mostly found in women's living space, decision-making, demand responsibility, information accessibility, caregiver role, body, and resource accessibility. In short, gender differences appeared in perception on safety culture and disaster vulnerability in decision-making field.
The purpose of this study was to investigate the effect of a stress relief program on school stress level and stress response and coping experience of female high school students and to compare the effects and influencing factors by stress level. The study subject includes 32 female high school students in South Korea. After a stress relief program, in the low-stress group, stress coping was the only significant factor influencing stress response and its explanatory power in the constructed regression model was 66.0% (F=16.27, p=.005). In the high-stress group, coping with friendship stress and problematic stress was a significant factor influencing stress response and its explanatory power in the constructed regression model was 47.0% (F=9.98, p=.001). It is found that a stress relief program could improve the stress coping strategies among female high school students and thus should be implemented in high schools to decrease school stress and response levels among adolescents in South Korea.
