In general, women's labor force participation follows a M-curve pattern because women's state of economic activity usually changes by their life course stage. This research attentions that the effect of sequence of life course as well as the effects of‘marriage bar’, or‘maternity leave’is very important in understanding women's chaning economic activity status. First, this research hypothesizes that women's four patterns of job career such as‘continuous pattern’,‘discontinuous pattern’,‘non-economic activity pattern’,‘marriage leave pattern’result a significant difference in social and demographic variables. Second, this research analyzes the effect of ordering and timing of life events on women's work transition. This research investigates labor market dynamics to conceptualize labor market behaviors using longitudinal data and sequence analysis and event history analysis. We find that four patterns of job career vary by age, educational attainment, having a certificate or not, their parents’human capital and health status. And we find that the ordering and timing of‘participation in labor market’and‘marriage’determine the pattern of women's work transition.

Drones, which show strong growth in the fourth industry, are commonly used for disaster response. In the event of an actual disaster, local governments should carry out 13 cooperative functions to respond to the disaster, but there are difficulties in collecting on-site information in places where it is difficult for people to access or grasp the situation. Based on the 13 collaborative functions that are essential for operations in the event of a disaster, a utilization plan of highly utilized drones was derived. Through the analysis of overseas cases and drone utilization by each department, a total of 10 out of 13 collaborative functions of the Disaster and Safety Countermeasures Headquarters (disaster situation management, emergency life safety support, emergency recovery, disaster resource support, traffic measures, medical and quarantine services, disaster site environment maintenance, social order maintenance, search, rescue, and emergency) were derived. These results can enhance the efficiency of the disaster response by presenting a plan to utilize drone images for each function.

The Buma Uprising, which took place in Busan and Masan from 16 to 20 October 1979, was a challenge against the contradictions of the Yushin Regime. Only after 6 days from the insurrection, the 10 26 Accident transpired, in which the then president Park Chung-hee was assassinated, and the Buma Uprising, which acted as the fuse to the shooting, remained as an 'incomplete uprising'. To commensurate with the subject of the paper 'The Truth about Buma Uprising and Historical Reflection', the purpose of this study is to explore how the uprising began, unfolded, and oppressed by comparing it with Busan Uprising and Masan Uprising. It also focuses to discuss, in detail, the effect of the demonstration by college students and the general public and suppression by the forces of the police and military on President Park and his government. This year, we celebrate the 39th anniversary of Buma Uprising, and with all the issues of discovering the truth, restoration of reputation and more, there are decisions and resolves to make including amendment of the legal system. However, there are certain groups of people who act as they led the uprising and mislead and exploit the facts of the events through illegitimate records and testimony, making it impossible to determine the truth. Discovering the truth will require acquisition of objective materials, testimony of those involved in the event and field research as well as imposition of legal and social punishment on those who distorted the truth about the event.

Objective : The aim of this study is to examine the characteristics of somatic symptoms in patients with PTSD according to trauma type. Methods : The subjects of this study were 84 patients diagnosed with PTSD according to the DSM-IVTR and CAPS criteria. The subjects ranged in age from 18 to 76 years, and they were recruited from 18 hospitals across the nation. All participants were asked about their trauma history, and they all completed the Davidson Trauma Scale (DTS), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), Impact of Event Scale-Revised (IES-R) and Korean-Physical Somatic Symptom Inventory (K-PSI). The items of the K-PSI were categorized into 5 groups according to organ system, and the participants were classified into 6 groups according to trauma type. We compared the results of the social demographical scale, DTS, BDI, STAI, IES-R and each recategorized subscale of the K-PSI among the six groups. Results : There were significant differences between the 6 groups in terms of the Korean-Physical Somatic Symptom Inventory scores for each organ system, except for the cardiopulmonary system, as well as the BDI scores. Post hoc analysis revealed differences between the combat-related trauma group and all other groups but not among any of the other groups. Conclusion : Our result showed that there were significant differences in the somatic symptom scores among the 6 trauma groups. However, patient age and the time elapsed since the traumatic event may have hada crucial influence on the result of this study.

The trust toward the researchers and their study activities in society has faltered, in the wake of the paper fabrication event of researcher, Hwang Woo-Suk's doctor research team. After the event, researcher community and scientific community have experienced many changes through the self-reflection or the process of insight meditation. Until now, we have experienced that when researcher community leads the way to try to show their efforts to eliminate the raised doubts throughly, the public support toward researcher community and the trust in its study activity have not faltered. Nevertheless, the path for the researchers to go is still far and rough because the opposite cases coping with research misconducts passively are much more. Therefore It's urgent that misconducts in the research and learning should be avoided from unnecessary overinterpretation. To practice it, above all it's important how well researcher or learner should be equipped with a system where decision is made autonomously and reasonably, regardless of the interests from all fields including politic, economic and social etc. It's also required that their systems should be meticulous enough to prevent such irrationality in advance before the misconduct instances are depreciated. In this context, I will investigate the reason why research and development on norms in research ethics and learning ethics is meaningful, not in a posteriori but a priori dimension, as the way to have researcher and learner prepare autonomous self-purification systems. It's essential that for the progress of an obvious argument, first, what research ethics and learning ethics are should be established and defined distinctly(2). Then in the process, it is also examined why research ethics and learning ethics need norms(3). Subsequently I will conclude the paper, arguing the reason why research ethics and learning ethics should be justified(4), if the norms in research ethics and learning ethics can be formulated(5).

Disaster of Sewol took place in one year. Meanwhile, the victim's family and the call time record academics have tried to record it. Ansan activists have moved to objectives such as civil records committee also pivotal. The citizens committee under the dictation recording oral history team has a diverse group of people associated with the time issue. bereaved families were collected from the oral as well as volunteers, religious personnel, activists, Ansan citizens and various people. Disasters around the world is also an important event to remember and honor the people together, and one of the most effective means to record There it is establishing an oral history archive. Does not leave a lot of nature history of sudden disasters that occur, as well as a tribute record dictation telling people of diverse perspectives on events helps a lot closer to the reality of the event. Erected in the National September 11 Memorial Museum to honor the Sept. 11 attacks and provide a variety of programs to chaerok dictation of the people involved with 9/11. To remember the 2013 Boston Marathon bombing 'Our Marathon' of crowdsourcing digital archive was built. In the archives of the local universities and institutions were created to collaborate actively and gathering oral history. Pan Am Flight 103 pieces terror has established an archive from Syracuse University. Here, neither graduates, faculty, and to the victim's family and friends gather and oral hitory. Disaster-related Sewol neither should be able to be used as in the case of foreign well, and it should continue to honor the victims of the collection. It also ought to occasion again to avoid this disaster on earth.

This study uses data from the 11th year(2016) to the 15th year(2020) of the Korea Welfare Panel(KOWEPS) for the five years that the survey was completed to predict the life satisfaction of each individual by generation, centered on single-person households. This is a longitudinal analysis using a latent growth model. The generational division was based on the turning point of a major event experienced by the cohort that brought about a decisive change in the socialization process, historical event, and technological development as factors. The analysis data used in this study were of 27,447 persons in the 15th year of the Korea Welfare Panel(2020), 2,778 persons who were single-person households even in the first year from the last 5 years, and 1,448 persons who were single-person households continuously for 5 years. Excluding those born in 1922 to 1944(843 persons), 605 persons born between 1945 and 1996 were included. As a result of the study, Generation Y(millennials) than Generation X(new generation) and Generation X generation than Baby Boomers showed higher overall life satisfaction. Since overall life satisfaction by generation does not have an effect on the rate of change, it was found that this difference remains the same for all generations.

Facial processing of different racial origin has been investigated at various levels including perceptual, emotional, and socio-cultural processing. Particularly, a good deal of studies have been conducted to show "other race effect (ORE)" to indicate that subtle facial information such as identity or emotional expressions are often under-processed in racial out-group members. However, few studies have investigated whether attentional modulation toward racial out-group faces could explain ORE. We investigated whether novelty-driven attentional mechanism is involved in face perception using event-related potential (ERP). Twenty-two Korean (KR) and nine Caucasian-American (AM) participants were presented with emotional faces from the two racial origins while they performed a gender categorization task. KRs showed significantly greater P3 amplitudes to AM than to KR faces indicating that the early attentional processing underlies differential perception of racial out-group faces. Interestingly, P3 was not up-regulated in the AM subjects when they were presented with KR faces, perhaps due to massive habituation to KR faces during everyday social interaction. These results indicate that racial out-group faces are highly salient stimuli which automatically occupy attentional resources, but easily habituated with repeated exposure to the racial-out group.

Ground subsidence on urban roads is a social issue that can lead to human and property damages. Therefore, it is crucial to detect underground cavities in advance and repair them. Underground cavity detection is mainly performed using ground penetrating radar (GPR) surveys. This process is time-consuming, as a massive amount of GPR data needs to be interpreted, and the results vary depending on the skills and subjectivity of experts. To address these problems, researchers have studied automation and quantification techniques for GPR data interpretation, and recent studies have focused on deep learning-based interpretation techniques. In this study, we described a hyperbolic event detection process based on deep learning for GPR data interpretation. To demonstrate this process, we implemented a series of algorithms introduced in the preexisting research step by step. First, a deep learning-based YOLOv3 object detection model was applied to automatically detect hyperbolic signals. Subsequently, only hyperbolic signals were extracted using the column-connection clustering (C3) algorithm. Finally, the horizontal locations of the underground cavities were determined using regression analysis. The hyperbolic event detection using the YOLOv3 object detection technique achieved 84% precision and a recall score of 92% based on AP50. The predicted horizontal locations of the four underground cavities were approximately 0.12 ~ 0.36 m away from their actual locations. Thus, we confirmed that the existing deep learning-based interpretation technique is reliable with regard to detecting the hyperbolic patterns indicating underground cavities.

As the proportion of sports events in the sports industry grows, the official sponsor market for sports events is also increasing. But because official sponsors are limited and expensive, some companies approach sporting events by way of Ambush marketing. This study is to analyze the differences of media exposure between official sponsors and general companies of mega sport events. To accomplish the purpose of the study, we collected text articles and analyzed them from the period of 2016 Rio Olympics, one year before the Olympics and one year after the Olympics. Web crawling was performed using Python for the collection of articles. Morphological and frequency analysis was performed using the KoNLP package and the TM package of statistical program R. In addition, the opinions of the related experts group were gathered to classify the companies or organizations in the media as the Organizing Committees for the Olympic Games(OCOGs), official sponsor, and general companies. As a result of the analysis, 5,220 times appeared related to the OCOGs, 7,845 times appeared related to the official sponsor, and 7,028 times appeared related to general companies. There isn't much difference in the frequency of exposure between official sponsors and general companies. It implies that Ambush marketing is recognized as a strategic marketing technique. The International Olympic Committee(IOC) has to recognize these social phenomena and establish reasonable standards for the marketing activities of official sponsors and general companies. And this study will serve as a basis for fair sponsor activities or marketing activities of sports events.
