In recent years, Computer-based learning, such as machine learning and deep learning in the computer field, is attracting attention. They start learning from the lowest level and propagate the result to the highest level to calculate the final result. Research literature has shown that systematic learning and growth can yield good results. However, systematic models based on systematic models are hard to find, compared to various and extensive research attempts. To this end, this paper proposes the first TNT(Transitive Nested Triangle)model, which is a growth and fusion model that can be used in various aspects. This model can be said to be a recursive model in which each function formed through geometric forms an organic hierarchical relationship, and the result is used again as they grow and converge to the top. That is, it is an analytical method called 'Horizontal Sibling Merges and Upward Convergence'. This model is applicable to various aspects. In this study, we focus on explaining the TNT model.

This paper examines the British imperialism found in Edith Nesbit's fantasy stories by looking at the function of magic and of the hierarchical relationships seen in the books. Although Edith Nesbit is relatively unknown in Korea, she is widely recognized as having had a great influence on the 20th century British literary world, and is also well-known for her political position as a socialist. Nesbit's fantasy books are commonly differentiated from other Victorian children's books written before her in that she created realistic and liberal children characters and rejected the adult didactic tone. While Nesbit's books have been recognized as revolutionary and being distinguished from other Victorian children's books, I suggest that the ideas found in her fantasy novels largely include the dominant Victorian message of British imperialism. This imperial ideology is delivered by the logic of magic and the multilateral hierarchies. The two magic creatures (The Psammead and the Phoenix) and the two magic items from an Oriental background (the Carpet and the Amulet) all have a magic power to grant people's wishes, wholeheartedly exercising their power and knowledge for the sake of the British characters. While the magic agents serve to fulfill the children's wishes, the children aim to please their parents and to benefit their family, showing layered hierarchies among the characters. Also, there is a hierarchical distinction between the magic items and the magic creatures in that the magic items have no voice to express themselves but only serve and obey the British children. The foreign characters that the children encounter in their adventures also cooperate with the British characters to help them to fulfill their goals. In short, magic frees the children from the adult-centered world but ultimately their free adventures serve their parents and other adults, and represent the ideals and hierarchical concepts of British imperialism. Thus, Nesbit's position as a modern writer seems to be ambiguous, switching between modern characterization and style, and the old Victorian imperial messages that also exist in her fantasy novels.

This paper addresses the design of srTCM (single rate Three Color Marker) described in RFC2697. It has proposed for srTCM to be used at the ingress of Differentiated Service network that provides AF PHB (Assured Forwarding Per Hop Behavior). srTCM is the marker with the metering function, and consists of the token updating function and the marking function. The token updating function uses the dual token bucket. The marking function compares the token values with the length of input packet, and then marks the result into IP QoS field (ToS field). This paper designs srTCM function and then implements it in one chip using VHDL and FPGA technology.

Recent studies have shown that the neural network-based binary code similarity detection technology performs well in vulnerability mining, plagiarism detection, and malicious code analysis. However, existing cross-architecture methods still suffer from insufficient feature characterization and low discrimination accuracy. To address these issues, this paper proposes a cross-architecture binary function similarity detection method based on composite feature model (SDCFM). Firstly, the binary function is converted into vector representation according to the proposed composite feature model, which is composed of instruction statistical features, control flow graph structural features, and application program interface calling behavioral features. Then, the composite features are embedded by the proposed hierarchical embedding network based on a graph neural network. In which, the block-level features and the function-level features are processed separately and finally fused into the embedding. In addition, to make the trained model more accurate and stable, our method utilizes the embeddings of predecessor nodes to modify the node embedding in the iterative updating process of the graph neural network. To assess the effectiveness of composite feature model, we contrast SDCFM with the state of art method on benchmark datasets. The experimental results show that SDCFM has good performance both on the area under the curve in the binary function similarity detection task and the vulnerable candidate function ranking in vulnerability search task.

Purpose: The purpose of this study is to explore the roles and function of family in mediating the relationship between depression and quality of life of patients with Parkinson's disease (PD). Most studies have found that depression is particularly common in patients with PD and further associated with poor quality of life. Family function, as a mediator, is based on a strength orientation perspective that emphasizes not only their responsibilities and risks but also recuperative powers and growth potential. Methods: Overall 157 adults with idiopathic Parkinson's disease were enrolled in this study via outpatient clinic and completed a set of assessment to measure depression using BDI, family APGAR questionnaire, and patients' quality of life using PDQ-8. Hierarchical multiple regression analysis was conducted to examine the mediating role of family APGAR score in the relationship between BDI and PDQ-8. Results: Patients' depression, gait disturbance, duration of illness, and family function were statistically significant on quality of life. These factors accounted for 60% of the variance in quality of life. Family function has a partial mediating effect on the relationship between depression and quality of life. Conclusion: Findings from the study suggest that although PD patients' depression impacts their quality of life, by having strong family function, the extent to which depression impacts the quality of life can be favorably mitigated. Additionally, these outcomes have important implications for future model development regarding PD patients.

Purpose: The purpose of this study was to explore the influence of cognitive function and depressive symptoms on instrumental activities of daily living (IADL) in addition to identify the factors associated with IADL in community-dwelling older adults. Methods: This was a descriptive study with cross-sectional design. Data were collected from July 2013 to June 2014. A total of 143 participants without dementia, depression and disability were enrolled in this study. Cognitive function was measured using Seoul verbal learning test (SVLT), digital span (forward/backward) and fist-edge-palm test. The Korean-IADL and Short Geriatric Depression Scale (S-GDS) were used. Data analysis was performed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and hierarchical regression. Results: Overall, a multiple regression model revealed that approximately 27.4% of total variability in IADL in the sample of community-dwelling older adults could be explained by the significant 12 variables in this model ($R^2=0.274$, F=5.467, p<.001). Age, having religion and cognitive function were the predictors of IADL in community-dwelling older adults. Conclusion: This study suggest that we need to monitor cognitive function in older to maintain the ability for IADL in older adults. Also, individualized program for improving older adults' IADL should be included in nursing intervention.

Recently, public organizations have been improving the classification in order to introduce records management reference table in accordance with the act on the management of public archives. However, there is no system to mount the revised records management reference table, and there is a problem in usability. The purpose of this study is to design a system function to manage the classification which is the foundation of records management for public organizations. In order to design the function, interviews with the records management specialists of the five public organizations were conducted. Based on this, we have designed a multi-classification system registration function, a hierarchical structure setting function of records, and a record management standard management function.

In this study, 230 subjects of medical examination were investigated to figure out the relationship with common carotid artery intima-media thickness and cardiac diastolic function. In addition, the change in the carotid artery intima-media thickness according to the presence or absence of metabolic syndrome was examined. As a result of the study the carotid artery intima-media thickness was thick as the age increased and there was a large difference in those in their 60s and over. There was no gender difference. As for metabolic syndrome the carotid artery intima-media thickness was thicker in the study subjects with high blood pressure diabetes and dyslipidemia. The correlation between the carotid artery intima-media thickness and diastolic function indexes was significant. As a result of hierarchical regression analysis the thicker the intima-media thickness in the carotid artery the lower cardiac diastolic function.

In [3], we showed that overintegration may be needed to obtain the optimal $H^1$ error rate for the $p$ version. In this paper, we examine the convergence of the $p$ version in practice, and comment on the implementation of the $p$ version in commercial codes. Also, we give an example of a problem with extremely rough coefficients, for which overintegration is necessary to obtain the optimal $H^1$ convergence rate.
