본 연구는 폐교로 인한 연금수급자가 근로소득 또는 사업소득 등 추가적인 소득이 발생할 경우에 기존 소득심사제도와 동일하게 적용을 하고 있는 현행 제도의 문제점을 지적하고 이에 대한 개선안을 제시하고자 한다. 폐교로 인한 퇴직연금수급자가 사학기관에 재취업을 하게 되면 연금은 전액 정지되지만, 일반 국민연금 가입기관에 재취업을 하게 되면 일반적인 소득심사를 적용받게 된다. 폐교에 따른 연금을 수령하는 연령층 중에는 일부 젊은 층도 포함되고 있어 근로활동이 왕성한 시기임에도 불구하고 연금을 수령하고 있어 결과적으로 사학연금 재정에 막대한 영향을 미치고 있다. 이러한 상황을 감안하여 재취업의 대상 기관에 따라 차별화되고 있는 현행 폐교 연금수급자의 지급정지에 대한 법 적용을 동일하게 적용할 여지가 있다고 판단된다. 본 연구에서는 다음과 같은 개선방안을 제시하였다. 첫째, 폐교로 인하여 퇴직할 경우에는 연금을 조기에 수령하게 되는데, 연금제도는 본래 은퇴 후의 소득을 보장받기 위한 것이나 현행 폐교로 인한 연금 지급은 근로가 가능한 젊은 층일 경우에도 지급하고 있어 추가적인 소득이 발생할 경우에는 퇴직소득심사제를 더욱 강화하여야 한다. 둘째, 연금 지급액보다 높은 추가 소득이 발생할 경우 또는 공무원 평균연금월액을 초과하는 경우에는 연금을 전액 또는 반액 정지하는 방안을 모색하여야 한다. 셋째, 연금재정의 안정화를 위하여 폐교로 인하여 연금을 수령하고 있는 수급자에 대하여는 현행보다 강화된 소득심사제를 적용하여야 한다. 본 연구는 최근 폐교로 인한 연금수급자가 증가하고 있는 상황하에서 퇴직소득심사제에 대한 개선안을 모색해보았다는 점에서 의의가 있다고 할 수 있다. 폐교로 인한 연금지급액은 해마다 급증하고 있는 추세에 있으며, 이로 인해 연금재정 소요액은 더욱 증가할 것으로 예상되고 있고 연금재정의 악화요인으로 작용하고 있다. 그러므로 폐교로 인한 연금을 수령 시에는 현행보다 강화된 소득심사의 적용이 필요하다고 본다.

우리나라는 도시화 및 산업화로 도시지역의 대부분이 불투수층으로 변화하였으며, 국지성 호우의증가로 홍수 저감시설의 방어능력이 취약한 실정이다. 따라서 홍수방어 개선을 위한 여러 방안들이 이루어지고 있으며, 그 중 저류지는 도시지역에서 유역 하류의 홍수피해 저감 및 흐름을 지체시켜 유출률을 감소시키는 시설물로 홍수 저감을 위한 시설물로 가장 많이 사용되고 있다. 저류지는 큰 규모일수록 유역의 하류지역에 설치할 경우 가장 큰 유출저감효과를 가지는 것으로 알려져 있다. 하지만 저류지의 위치를 유역의 하류가 아닌 상류지역에 설치할 경우에는 단기간 강우의 시간적 분포가 강우 초기에 집중될 경우 저류지의 허용용량이 초기에 도달하게 되어 추가적인 강우가 발생할 경우 본래의 역할을 하지 못하는 경우가 빈번하게 발생하고 있다. 그러므로 다양한 강우강도 및 시간적 분포를 고려하여 유역의 특성 및 저류지의 설치위치에 따른 관계를 분석할 필요가 있다. 본 연구에서는 도시화, 산업화 인구집중으로 인해 동일규모의 강우에서도 우수유출이 증대되고 있는 도시지역에서 원활한 내수배제를 위해 기존의 우수관거를 연계한 저류시스템인 간선저류지 개념을 적용하여 강우강도 및 시간적 분포에 따른 간선저류지의 관련매개변수를 분석하였다. 대상유역은 세장형, 집중형, 중앙형의 3가지 형상의 가상유역으로 선정하여 다양한 지속기간의 강우량을 적용하였으며, 간선저류지의 설치위치는 전체 유역면적에 대한 저류지 상류부 면적의 비(저류지 상류부 면적비, DUAR ; Dimensionless Upstream Area Ratio)를 20%, 40%, 60%, 80%로 변화시키면서 강우의 시간적 분포에 따른 간선저류지의 매개변수 분석에 관한 연구를 진행하였다.

With the emergence of convolutional neural network in the field of machine learning, the model for solving image processing problems has seen rapid development. However, the computing resources required are also rising, making it difficult to learn from a typical environment. Attention mechanism is originally proposed to prevent the gradient vanishing problem of the recurrent neural network, but this can also be used in a direction favorable to learning of the convolutional neural network. In this paper, attention mechanism is applied to convolutional neural network, and the excellence of the proposed method is demonstrated through the comparison of learning time and performance difference at this time. The proposed model showed that both learning time and performance were superior in object detection based on YOLO compared to models without attention mechanism, and experimentally demonstrated that learning time could be significantly reduced. In addition, this is expected to increase accessibility to machine learning by end users.

Originally confucianism is closer to communitarianism than to individualism. The ideal of confucianism is to realize ethical community. Chu Hsi's theory of the Song dynasty reestablishes the ideal of ethical community and dignitaries(士大夫) take the job to realize it as their own vocation. There are many developed 'family clans and kinsfolk societies', 'local covenants and sacred storehouses' and 'private academies' in the Chosun dynasty as in the Song dynasty. These communities are three kinds of axial confucian community, which are both natural ascriptive groups and voluntary contract groups in nature. Communities of Chosun dynasty are to strengthen the solidarity through friendship and mutual help as well as to cultivate good customs in society. Also these traditional communities are managed by democratic procedures, as these are originally voluntary contract groups. On the other hand, traditional neo-confucian self-training theories like that individual personality should be harmony with general order, or one should pursuit his private interest according to fair principles are the process of sublimation private individual into public citizen.

Through excavation on Anapji Pond from March 1975 to December 1976, it was discovered that the whole area around Anapji Pond had been called East Palace (東宮) since 7th century and that the original name of East Palace was Wolji Palace (月池宮) through excavation in 1980. The excavation proved that the original name of Anapji Pond was 'Wolji.' In academic world, there are many scholars who recognize this place as the Crown Prince's palace for being called East Palace. East Palace (which is read Dong Palace with pronunciation in Korean alphabet) actually is another name for Crown Prince's palace. This place, however, cannot have served as Crown Prince's palace as 'independent, exclusive space.' After 7th century, there were detached palaces in Silla including East Palace South Palace North Palace and Yang Palace other than Jeong Palace in Wolseong. East Palace is a palace located in the east. The palace's name is based on bearing and it does not indicate Crown Prince's palace. This article proves that East Palace cannot have been Crown Prince's palace through newly analyzing materials related to Wolji Palace.

In some practical circumstances, the ability of a signer should be restricted. In group signature schemes, a group member of a group may be allowed to generate signatures up to a certain number of times according to his/her position in the group. In proxy signature schemes, an original signer may want to allow a proxy signer to generate a certain number of signatures on behalf of the original signer. In the paper, we present signature schemes, called c-times signature schemes, that restrict the signing ability of a signer up to c times for pre-defined value c at set-up. The notion of c-times signature schemes are formally defined, and generic transformation from a signature scheme to a c-times signature scheme is suggested. The proposed scheme has a self-enforcement property such that if a signer generates c+1 or more signatures, his/her signature is forged. As a specific example, we present a secure c-times signature scheme $^c$DSA based on the DSA (Digital Signature Algorithm) by using a threshold scheme. Our transformation can be applied to other ElGamal-like signature schemes as well.

Semantic image segmentation technology in the field of computer vision is a technology that classifies an image by dividing it into pixels. This technique is also rapidly improving performance using a machine learning method, and a high possibility of utilizing information in units of pixels is drawing attention. However, this technology has been raised from the early days until recently for 'lack of detailed segmentation' problem. Since this problem was caused by increasing the size of the label map, it was expected that the label map could be improved by using the edge map of the original image with detailed edge information. Therefore, in this paper, we propose a post-processing algorithm that maintains semantic image segmentation based on learning, but modifies the resulting label map based on the edge map of the original image. After applying the algorithm to the existing method, when comparing similar applications before and after, approximately 1.74% pixels and 1.35% IoU (Intersection of Union) were applied, and when analyzing the results, the precise targeting fine segmentation function was improved.

Chest X-ray is radiological examination for xeamining the lungs and haert, and is particularly widely used for diagnosing lung disease. Since the quality of these chest X-rays can affect the doctor's diagnosis, the process of evaluating the quality must necessarily go through. This process can involve the subjectivity of radiologists and is manual, so it takes a lot of time and csot. Therefore, in this paper, based on the chest X-ray quality assessment guidelines used in clinical settings, we propose a tool that automates the five quality assessments of artificial shadow, coverage, patient posture, inspiratory level, and permeability. The proposed tool reduces the time and cost required for quality judgment, and can be further utilized in the pre-processing process of selecting high-quality learning data for the development of a learning model for diagnosing chest lesions.

This study analyzes how the health program is implemented by political and economic factors in the case of Minga Ambiental program in Paraguay. In the field of critical medical anthropology, the practice of health care programs explains that socio-cultural and political and economic factors can be the main variables besides the primary purpose of preventing and eradicating the disease. In the same vein, this study also analyzed how community-based health programs operate by various external factors. As a result, the Minga Ambiental program is a health program called Dengue Fever, which has been tended to be sustained and expanded by various actors, including politicians and corporations in countries and communities, despite concerns about effectiveness. In this case, this study found that health programs can be operated by political and economic relations different from their original purpose, and are intertwined in various social contexts by various actors in constructing health programs.
