This study attempted to find a Christian religious alternative to the seriousness of the problem of low birth rate which has become a national and social problem, and its alternative. Korea is a low birth rate country. The phenomenon of low birth rate and childbirth avoidance is a reality that not only are national problems but also Korean churches are experiencing serious problems, and will continue to affect them. It will affect the church in four major ways. First, is a sharp decline in the number of members. Second, is the decline of Sunday schools. Third, various family problems and generational conflicts will arise. And it brings problems such as a crisis of faith among members. Young people living today have an unconventional attitude toward marriage, childbirth, and parenting. But for Christians, childbirth is a way of living in that God blessed us to "be fruitful, multiply, and fill the earth." In other words, childbirth must be recognized as a blessing from God, not a human decision. Therefore, we must know how precious the fetus is in front of God and that it is a precious life. Thus, we should be interested in how to nurture the life God has given. To do so the church's role is education is to shape the value of life from a biblical perspective. Therefore the church needs to see how the Christian faith of young and married couples who are about to marry, give birth, and raise children, affects the childbirth and rearing of children. And it is necessary to study what the role of church and Christian education is to solve the problem of low birth rate and to suggest alternatives. For this study, we will first identify the factors of low birth rate. Then we will confirm childbirth and the blessing of God through the Bible. Finally, the role of the church in low birth rate and educational alternatives will be presented.

An abnormal object refers to a person, an object, or a mechanical device that performs abnormal and unusual behavior and needs observation or supervision. In order to detect this through artificial intelligence algorithm without continuous human intervention, a method of observing the specificity of temporal features using optical flow technique is widely used. In this study, an abnormal situation is identified by learning an algorithm that translates an input image frame to an optical flow image using a Generative Adversarial Network (GAN). In particular, we propose a technique that improves the pre-processing process to exclude unnecessary outliers and the post-processing process to increase the accuracy of identification in the test dataset after learning to improve the performance of the model's abnormal behavior identification. UCSD Pedestrian and UMN Unusual Crowd Activity were used as training datasets to detect abnormal behavior. For the proposed method, the frame-level AUC 0.9450 and EER 0.1317 were shown in the UCSD Ped2 dataset, which shows performance improvement compared to the models in the previous studies.

X-ray general radiography is the simplest and most important one to get a lot of information. Nevertheless, current x-ray general radiography does not observation in-depth observation. Information about the anatomy of the human body and changes in disease in x-ray general radiography can be obtained but it is difficult to determine the size and shape of the actual lesion due to the disadvantage of expanding the image. In this study, PA and LAT images were acquired and cancer magnification was calculated in the images by measuring the distance of cancer samples. By adjusting the magnification the actual cancer length and thickness were measured and compared with the CT image and the actual cancer sample size. After the PA and LAT images of the inserted 6.0 mm cancer sample were obtained and the magnification was corrected, the length was 5.9 mm and the thickness was 6.1 mm. This value was measured similarly to the actual. The problem of obtaining the magnification that needs to know the actual length from the detector to the cancer sample was secured by obtaining the magnification through PA and LAT images and it is possible to accurately measure the cancer sample size. X-ray general radiography may provide useful information in situations where CT imaging is difficult.

It is not easy to predict the future society in the rapidly changing present, but it is said that a new social environment of sensibility and virtuality will come, and we should pay attention to the fact that women have entered this as the subject. This study is a literature review study on gender roles. Through the study, it was found that gender stereotypes that exist in our society allow men to enjoy a lot of vested rights just by being male, and that women have to endure pain because they are women is accepted as a matter of course. Living in the 21st century, we were able to know the reality that we could not escape the pre-modern patriarchal ideology and still worshiped the idea of preferring boys. Through this study, unlike other elderly groups, elderly people who live alone are likely to be cut off from society and lead a limited life in their own world. However, through the efforts of the government, local organizations, and individuals, the goal of welfare for the elderly is to increase the satisfaction of life for the elderly living alone so that they can enjoy a successful old age. From this point of view, the support measures for the elderly living alone will be effective only when systematic and complementary in various dimensions such as family structure, physical, economic, and social aspects.

Currently, around 40 million people worldwide are living with human immunodeficiency virus (HIV) infection making HIV a critical global health risk. Present therapies for HIV infection consist of drug cocktails that target different steps of the HIV life cycle to prevent infection, replication, and release of the virus. Due to its mutating nature, drug resistance coupled with side-effects of long-term drug use, novel strategies, and pharmaceuticals to treat and manage HIV infection are constant needs and continuously being studied. Plants allocate a major repertoire of chemical diversity and are therefore regarded as an important source of new bioactive agents that can be utilized against HIV. Since the early 1990s, upon recommendations of the World Health Organization, numerous studies reported phytochemicals from different structural classes such as flavonoids, coumarins, tannins and terpenes with strong inhibitory effects against HIV infection. The present review gathered and presented recent research (2021-present) on plant extracts and phytochemicals that exhibit anti-HIV properties with the aim of providing insights into future studies where ethnomedical and underutilized plant sources may yield important natural products against HIV. Considering the relation and importance of HIV treatment with current viral infection risks such as SARS-CoV-2, screening plants for anti-HIV agents is an important step towards the discovery of novel antivirals.

The full impact of COVID-19 has yet to be felt: while it may not define the new decade, it is clear that its immediate significance was to test many of the basic operating assumptions and procedures of global civilization. Even as vaccines are developed and utilized and even as it is possible to see the beginning of the end of COVID-19 as a discrete historical event, it remains unclear as to its ultimate importance. That said, it is evident that the academic exploration of Southeast Asia will also be affected by both the global and regional experiences of the pandemic. "Breakthroughs of Area Studies and ASEAN in the Era of Homo Untact" promises to help reconceptualize the study of the region by highlighting the importance of redefined spatial relationships and new potentially depersonalized modes of communication. This paper acknowledges these issues by suggesting that the transformations caused by the pandemic should motivate scholars to raise new questions about how to understand humanity-particularly as it is defined by societies, nations and regions. Given that COVID-19 (and the response to it) has altered many of the fundamental rhythms of globalized regions, there is sufficient warrant for re-examining both the ways in which disease, health and their related spaces affect the perceptions of Southeast Asia. To achieve "breakthroughs" into the investigation of the region, it makes sense to have another glance at the ways in which the discourses about diseases and health may have helped to inscribe definitions of Southeast Asia-or, at the very least, the nations, societies and peoples who live within it. In order to at least consider these larger issues, the discussion will concentrate on a formative moment in the conceptualization of Southeast Asia-British engagement with the region in the late 18^th and early 19^th centuries. To that end three themes will be highlighted: (1) the role that British diplomatic and military narratives played in establishing the information priorities required for the construction of colonial knowledge; (2) the importance not only of "colonial knowledge" but information making in its own right; (3) in anticipation of the use of big data, the manner in which manufactured information (related to space and disease) could function in shaping early British perceptions of Southeast Asia-particularly in Batavia and Java. This discussion will suggest that rather than see social distancing or increased communication as the greatest outcome of COVID-19, instead it will be the use of data-that is, big, aggregated biometric data which have not only shaped responses to the pandemic, but remain likely to produce the reconceptualization of both information and knowledge about the region in a way that will be at least as great as that which took place to meet the needs of the "New Imperialism." Furthermore, the definition and articulation of Southeast Asia has often reflected political and security considerations. Yet, the experience of COVID-19 could prove that data and security are now fused into a set of interests critical to policy-makers. Given that the pandemic should accelerate many existing trends, it might be foreseen these developments will herald the triumph of homo indicina: an epistemic condition whereby the human subject has become a kind of index for its harvestable data. If so, the "breakthroughs" for those who study Southeast Asia will follow in due course.

Given the ongoing discussion regarding remote music therapy following the COVID-19 pandemic and the pivotal role of parental involvement in it, this study investigated parents' perceptions on their roles in a synchronous videoconferencing music therapy for their children with developmental disabilities. A total of 32 participants participated in an online survey comprising 68 questions. Descriptive statistics summarized the collected responses, and Pearson's correlation was conducted to examine the relationship between perceived parental roles, psychological burden, and willingness to participate in future remote music therapy. The findings showed that parents of children with developmental disabilities acknowledged the benefits of tele-music therapy and possessed substantial information about its implementation. Furthermore, they reported their roles of providing physical, participatory, and mediating support. As parents exhibited greater satisfaction with their role in supporting their children's participation or managing their off-task behaviors, they perceived reduced psychological burden. These findings hold significant implications for expansion of tele-music therapy strategies to address the unique needs of children with developmental disabilities and support their parents as immediate mediators for their children.

Early detection of schedule delay in field construction activities is vital to project management. It provides the opportunity to initiate remedial actions and increases the chance of controlling such overruns or minimizing their impacts. This entails project managers to design, implement, and maintain a systematic approach for progress monitoring to promptly identify, process and communicate discrepancies between actual and as-planned performances as early as possible. Despite importance, systematic implementation of progress monitoring is challenging: (1) Current progress monitoring is time-consuming as it needs extensive as-planned and as-built data collection; (2) The excessive amount of work required to be performed may cause human-errors and reduce the quality of manually collected data and since only an approximate visual inspection is usually performed, makes the collected data subjective; (3) Existing methods of progress monitoring are also non-systematic and may also create a time-lag between the time progress is reported and the time progress is actually accomplished; (4) Progress reports are visually complex, and do not reflect spatial aspects of construction; and (5) Current reporting methods increase the time required to describe and explain progress in coordination meetings and in turn could delay the decision making process. In summary, with current methods, it may be not be easy to understand the progress situation clearly and quickly. To overcome such inefficiencies, this research focuses on exploring application of unsorted daily progress photograph logs - available on any construction site - as well as IFC-based 4D models for progress monitoring. Our approach is based on computing, from the images themselves, the photographer's locations and orientations, along with a sparse 3D geometric representation of the as-built scene using daily progress photographs and superimposition of the reconstructed scene over the as-planned 4D model. Within such an environment, progress photographs are registered in the virtual as-planned environment, allowing a large unstructured collection of daily construction images to be interactively explored. In addition, sparse reconstructed scenes superimposed over 4D models allow site images to be geo-registered with the as-planned components and consequently, a location-based image processing technique to be implemented and progress data to be extracted automatically. The result of progress comparison study between as-planned and as-built performances can subsequently be visualized in the D4AR - 4D Augmented Reality - environment using a traffic light metaphor. In such an environment, project participants would be able to: 1) use the 4D as-planned model as a baseline for progress monitoring, compare it to daily construction photographs and study workspace logistics; 2) interactively and remotely explore registered construction photographs in a 3D environment; 3) analyze registered images and quantify as-built progress; 4) measure discrepancies between as-planned and as-built performances; and 5) visually represent progress discrepancies through superimposition of 4D as-planned models over progress photographs, make control decisions and effectively communicate those with project participants. We present our preliminary results on two ongoing construction projects and discuss implementation, perceived benefits and future potential enhancement of this new technology in construction, in all fronts of automatic data collection, processing and communication.

This paper examines middle powers' ODA policy in the post cold war era and discusses its implication for Korean aid strategy. Middle powers' ODA has been more successful than that of super powers in promoting donors' positive images and in stimulating recipient countries' development. Middle powers tend to pursue multilateral solutions to international problems often by taking a mediator role, and their ODA policies set them apart from the great players in international politics. Middle powers' ODA is primarily aimed at reducing poverty and protecting human rights in least developed countries where humanitarian aid needs the most rather than promoting donors' interests. Also, middle powers have provided bilateral untied aid in the sectors of food aid and emergency relief and steadily devoted about 0.7% of their gross national income to ODA. Meanwhile, Korea as an emerging middle power and a new donor has been implementing its own aid strategy under the name of the Korean development model since the post cold war period. The Korean ODA was not successful in building donors' positive images by simply following the short term strategies of US and Japan. Yet, its ODA policy has been quite effective in sustaining local development by creating specific niches in which the country can specialize in. In specific, Korea has focused on developing the sectors of information and communication technology and industry energy in recipients' countries by maximizing its comparative advantage.

Child policy has focused on needy children with special emphasis on residual services but youth policy has implemented to promote capabilities of general adolescents by various activities. The fragmented implementation of child-youth policy by several ministries resulted in possible redundancy of target groups and insufficient service delivery system. Thus, the Ministry of Health, Welfare, and Family Affairs has pushed forward to integrate service delivery systems in child-youth policy after the former Ministry of Health and Welfare and the Government Youth Commission were integrated as part of a government reorganization plan. The purpose of this study is to review limitations of Lee Myung-bak government's plan to integrate child-youth policy and to make important suggestions for effective integration. Lee Myung-bak government's plan seeks to help children and adolescents prepare for the future and move forward with dreams and hope. However, this plan has fatal problems of overemphasizing the efficiency of finance without expansion of budget for children and adolescents. To achieve well-being tailored to one's life cycle, the full-scale expansion of budget is indispensible through the induction of the special fund or the special tax for children and adolescents. Fortunately, Lee Myung-bak government recognized child-youth policy as the social investment that would heighten national competitiveness in the long term, but there was insufficient child-youth policy infrastructure for new implementation. Therefore, Lee Myung-bak government needs a new design for integrated and universal child-youth policy that should take into account national human resource development plan and its economic development policy. The public responsibility for children and adolescents should be strengthened and, in addition, the network function in service delivery system should be complemented.
