This study uses qualitative data to examine the dynamics and barriers of the delayed family formation phenomenon among the never-married professionals in Korea. The data was drawn from focus groups of 14 never-married professionals aged 28 through 40. The investigation depicts several dimensions of the circumstances of never-married professionals that have not garnered much attention in the literature. This research provides initial evidence of critical influences within the socio-cultural contexts of the participants' dating behaviors as well as the willingness to many. Two different realities, based on gender, were discovered: both male and female voluntarily delayed marriage to pursue their career, education and success. As both reached their career goals, however, male participants experienced a rise in their value as a marriage prospect whereas females experienced decreased value as a marriage prospect. Hence, neo-traditional familism was the dominant value among the participants, but it also functioned as a major barrier to family formation because in the present value system, female professionals, must still struggle with the dual burdens of work and family management.

In this paper, a new saliency map generation method is discussed which extracts objects effectively using extracted Salient Region. Feature map is constructed first using four features of edge, hue of HSV color model, focus and entropy and then conspicuity map is generated from Center Surround Differences using the feature map. Final saliency map is constructed by the combination of conspicuity maps. Saliency map generated using this procedure is compared to the conventional technique and confirmed that new technique has better results.

Attention Deficit-Hyperactivity Disorder(ADHD) is the most common psychiatric disorder in school-age children which is increasing gradually. It is hard for ADHD children to focus on particular stimulus for a long time. ADHD children are characterized by hyperactivity which shows in behaviors like, talking too much, getting up from their seats without permission, running around, keep on moving their arms and legs. ADHD children have problems with impulse controlling that they tend to fall and get into an accident very often. Thus dentist's attention and care must increase when dental treatment is performed with ADHD children since behavior control, oral hygiene problems, and trauma might be expected. By using sedative drugs and psychological behavior control, chief complaint was resolved in a 8-years-old female diagnosed for ADHD.

Semantic role labeling task(SRL) is to extract predicate and arguments such as agent, patient, place, time. In the previously SRL task studies, a pipeline method extracting linguistic features of sentence has been proposed, but in this method, errors of each extraction work in the pipeline affect semantic role labeling performance. Therefore, methods using End-to-End neural network model have recently been proposed. In this paper, we propose a neural network model using the Biaffine Average Attention model for SRL task. The proposed model consists of a structure that can focus on the entire sentence information regardless of the distance between the predicate in the sentence and the arguments, instead of LSTM model that uses the surrounding information for prediction of a specific token proposed in the previous studies. For evaluation, we used F1 scores to compare two models based BERT model that proposed in existing studies using F1 scores, and found that 76.21% performance was higher than comparison models.

Involvement of a multidisciplinary team in cancer care may have added benefits over the existing system of patient management. A paradigm shift in the current patient management would allow more focus on nutritional support, in addition to clinical care. Malnutrition, a common problem in cancer patients, needs special attention from the early days of cancer care to improve quality of life and treatment outcomes. Patient management teams with trained oncology dietitians may provide quality personalized nutritional care to cancer patients.

Optimizing transient response for both tracking reference signals and disturbance rejection is determined by the poles and zeros of the transfer function. Thus, optimal pole assignment and how should weighting matrix for the performance index be chosen is very important to achieve optimum transient response. This paper focus its attention on the choosing and analysis of weighting matrix for optimum pole assignment. Optimum pole assignment is defined for linear time-invariant continuous systems.

The purpose of this research is to analyze elementary students' attention characteristics through attention test and eye tracking on real science classes. The SMI's ETG(eye tracker glasses) mobile eye tracker was used to analyze the attention process of elementary students'. The sampling rate of the ETG is 30Hz. The participants of attention test were elementary 155 6th-grade elementary students and the participants for the eye-tracker were six 6th-grade male students. The eye movements were analyzed using the 'BeGaze Mobile Video Analysis Package' program. The results of this research are as follows. First, the attention test results of elementary students showed high correlation between selective attention and sustained attention (.85) and low correlation between selective attention and self-regulation (.32). Second, the attention types of elementary students were divided into four; attention, inattention, easygoing and hasty. Third, elementary students' attention were divided into top-down, bottom-up, default mode network through analysis of elementary students′ eye-movements during real science classes. Also their attention shift occurred frequently due to various reasons in real class situation. There were three reasons that made elementary students fail to handle knowledge-dependent top-down attention; 1) the cognitive failure of target caused by failing to focus attention, 2) the absence of prior knowledge on target object, 3) the analogical failure of prior knowledge. Finally, elementary students' attention process were schematized based on the analysis of students' eye movements and attention test. This research is expected to be utilized as basic data for developing effective teaching strategies, teaching-learning models and instructional materials.

The purpose of this study was to investigate the effect of performing a cognitive task during treadmill walking on the stride rate variability. Ten university students(age $24.0{\pm}0.25$, height $172{\pm}3.1cm$, weight $66{\pm}5.3kg$) were participated in dual task experiments which consist of both walking alone and walking with a cognitive task. Two-back task was selected for the cognitive task since it did not have learning effect during the experimental procedure.3D motion analysis system was used to measure subject's position data by changing walking speed with 4.8, 5.6, 6.4, 6.8, and 7.2 km/hr. Stride rate was calculated by the time between heel contact and heel contact. Accuracy rate of a cognitive task during walking, coefficient of variance, allometric scaling methods and Fano factor were used to estimated the stride rate variability. As the walking speed increased, accuracy rate decreased and the logarithmic value of Fano factor increased which showed the statistical difference. Thus it can be concluded that the gait control mechanism is distracted by the secondary attention focus which is the cognitive task ie. two-back task. Further study is needed to clarify this by increasing the number of subject and experiment time.

The 19th century could not relatively receive attention from local researchers because it was treated as the past cut off from the present as the formative period of modern states of Latin America. According to the characteristics of area studies which focus on changes of politics and society, studies on past affairs could not have been the main focus of attention. But as new liberalism has appeared in Latin America, is throwing the spotlight on liberalism. In addition, the studies on the 19th century have been activated and gradually expanded. And interpretation about the 19th century's history has been variously arranged. Especially, discussion on liberalism and conservatism was established as the key words which can understand and reconsider Latin America in the 19th century. Colombian liberalism which could not overcome heritage of the colonial period in the 19th century and did appear advocating reformation was another form of authoritarianism. Reformation promoted by liberalism was utilized to keep privilege of the ruling class, not to remove the social and economic structure derived from the colonial period. New reformist forces which advocated mercantilism after the middle of the 19th century but they were formed based on the existing system. Colombian Liberal Party was developed as "Another name of conservatization" by reflecting understanding of the conservatives. Colombian liberalists preferred federalism to cut off from repressive characteristics of Spanish colonial rule and secure autonomy of local control through reformation based on economic understanding. Therefore, discussion on the form of government which focused on federalism and centralism acted as the causes of conflict between Colombian liberalism and conservatism. Based on this point, this study tries to analyze liberalism reforms which is the main issue in the Colombian history in the 19th century and consider history of Colombian political conflicts focusing on federalism. The origin of Violencia which is the political violence and Colombian history in the 19th century which has been a series of rebellion can be considered through this procedure.
