Previous studies on the effect of fashion therapy have been conducted with psychiatric patients; however, this study explores the effects in fashion therapy for women with non-pathological problems. Previous studies did show if the effect of fashion therapy could be maintained continuously; therefore, we intend to examine the existence of the long-term effects of fashion therapy in an empirical manner and provide implications for social and public interest. This study used a qualitative approach to investigate the effects of fashion therapy with the following results. Low self-esteem, negative emotions, and rigid thinking symptoms appeared by numerous stress factors, and various changes were made through fashion therapy. Emotional changes such as positive emotions and feeling of achievement, and psychological changes including self-concept formation, change of sight and self-esteem improvement appeared. Sociological and behavioral changes were also identified. We found the maintained and long term effects of fashion therapy; therefore, study provides academic implications to reconsider the social value of fashion.

Background: So far there is no confidence in the basics of acupoint/meridian phenomena, specifically in spatial and temporal electrical manifestations in the skin. Methods: Using the skin electrodynamic introscopy, the skin areas of 32 × 64 mm² were monitored for spectral electrical impedance landscape with spatial resolution of 1 mm, at 2 kHz and 1 MHz frequencies. The detailed baseline and 2D test-induced 2 kHz-impedance phase dynamics and the 4-parameter time plots of dozens of individual points in the St32-34 regions were examined in a healthy participant and a patient with mild gastritis. Non-thermal stimuli were used: (1) (for the sick subject), microwaves and ultraviolet radiation applied alternately from opposite directions of the meridian; and (2) (for the healthy one) microwaves to St17, and cathodic/anodic stimulation of the outermost St45, alternately. Results: In both cases, the following phenomena have been observed: emergence of in-phase and/or antiphase coherent structures, exceeding the acupoint conditional size of 1 cm; collective movement along the meridian; reversible with a reversed stimulus; counter-directional dynamics of both whole structures and adjacent points; local abnormalities in sensitivity and dynamics of the 1 MHz and 2 kHz parameters indicating existence of different waveguide paths. Conclusion: It is assumed that these findings necessitate reconsideration of some basic methodological issues regarding neurogenic/acupuncture points as spatial and temporal phenomena; this requires development of an appropriate approach for identifying the acuzones patterns. These findings may be used for developing new approaches to personalized/controlled therapy/treatment.

In this paper, we have studied dynamics of fractional order mathematical model of malaria transmission for two groups of human population say semi-immune and non-immune along with growing stages of mosquito vector. The present fractional order mathematical model is the extension of integer order mathematical model proposed by Ousmane Koutou et al. For this study, Atangana-Baleanu fractional order derivative in Caputo sense has been implemented. In the view of memory effect of fractional derivative, this model has been found more realistic than integer order model of malaria and helps to understand dynamical behaviour of malaria epidemic in depth. We have analysed the proposed model for two precisely defined set of parameters and initial value conditions. The uniqueness and existence of present model has been proved by Lipschitz conditions and fixed point theorem. Generalised Euler method is used to analyse numerical results. It is observed that this model is more dynamic as we have considered all classes of human population and mosquito vector to analyse the dynamics of malaria.

Let a and b be positive integers, and let V (G), ��(G), and ��2(G) be the vertex set of a graph G, the minimum degree of G, and the minimum degree sum of two non-adjacent vertices in V (G), respectively. An even [a, b]-factor of a graph G is a spanning subgraph H such that for every vertex v ∈ V (G), dH(v) is even and a ≤ dH(v) ≤ b, where dH(v) is the degree of v in H. Matsuda conjectured that if G is an n-vertex 2-edge-connected graph such that $n{\geq}2a+b+{\frac{a^2-3a}{b}}-2$, ��(G) ≥ a, and ${\sigma}_2(G){\geq}{\frac{2an}{a+b}}$, then G has an even [a, b]-factor. In this paper, we provide counterexamples, which are highly connected. Furthermore, we give sharp sufficient conditions for a graph to have an even [a, b]-factor. For even an, we conjecture a lower bound for the largest eigenvalue in an n-vertex graph to have an [a, b]-factor.

To solve the problems of heavy computing load and system transmission pressure in energy internet (EI), we establish a three-tier cloud-edge integrated EI network based on a cloud-edge collaborative computing to achieve the tradeoff between energy consumption and the system delay. A joint optimization problem for resource allocation and task offloading in the threetier cloud-edge integrated EI network is formulated to minimize the total system cost under the constraints of the task scheduling binary variables of each sensor node, the maximum uplink transmit power of each sensor node, the limited computation capability of the sensor node and the maximum computation resource of each edge server, which is a Mixed Integer Non-linear Programming (MINLP) problem. To solve the problem, we propose a joint task offloading and resource allocation algorithm (JTOARA), which is decomposed into three subproblems including the uplink transmission power allocation sub-problem, the computation resource allocation sub-problem, and the offloading scheme selection subproblem. Then, the power allocation of each sensor node is achieved by bisection search algorithm, which has a fast convergence. While the computation resource allocation is derived by line optimization method and convex optimization theory. Finally, to achieve the optimal task offloading, we propose a cloud-edge collaborative computation offloading schemes based on game theory and prove the existence of Nash Equilibrium. The simulation results demonstrate that our proposed algorithm can improve output performance as comparing with the conventional algorithms, and its performance is close to the that of the enumerative algorithm.

Objectives: In Japan, there are many disasters such as earthquakes and tsunamis, and because of the high temperature and humid climate, health education for food poisoning may be particularly important. In addition, sexual problems caused by precociousness of adolescents, smoking and drinking are already serious socially important problems, and addiction problems are also emerging. Methods: Various publications from Japanese governments, interest groups such as government officers, health center workers, and people from health educators. For the information of Korean health education conditions, a current health educator and people from middle and high schools. Results: In 2012, based on the "Investigation Report on the Mind Care of Children in Emergency Disasters" from the Ministry of Education, Culture, Sports, Science and Technology, the Post-traumatic stress disorder (PTSD) situation of children in East Japan affected areas was discovered, and health education became important. In 2014, the "School Health and Safety Act Enforcement Rule" was amended, and health checkups are emphasized as part of school health. Conclusions: School health education in Japan differs from other health care systems in many ways with the system of Korea in the context of non-existence of official health education curriculum. Therefore, the purpose of this study is to develope how the curriculum of school health education in Korea.

This thesis aims to explore another possibility of comparative literature in the light of translation. Comparative literature has been criticized for its Eurocentrism to attempt to assimilate all differences from other cultures and national literatures into the frame of the Western. On the other hand, it has been haunted by the anxiety of "unhomliness", which means it doesn't have a stable and definable terrain as an independent disciplinary. However, it can offer the possibility to overcome its limitation and thematize in- betweenness of diverse terrains due to its fluid and ambiguous position and identity of discipline. When it deals with the issue of in-betweenness, 'the Untranslatable' can be an helpful apparatus to analyze comparative literature through translation theories. Along with the recent change in the study of comparative literature under the influence of transnationalism and hybridization, the role of translation which has been disregarded for a long time is being reevaluated. Translation functions to transfer literary works beyond boundaries of languages, whereas it visualizes incommensurable differences through the failure of finding ultimate equivalences between languages and arriving at one single meaning. The existence of the untranslatable suggests that the attempt to totalize differences is unfeasible, thereby makes comparison unending. Salman Rushdie's Shalimar the Clown can be an appropriate instance that the untranslatable was used as a literary technique to show unreducible alterity of non-Western language and culture.

The period of a recent streamcipher proposal Edon80 is analyzed. The designers of Edon80 had projected a period of $2^{103}$ Even though this could indeed be the average keystream Period, we show that for a randomly chosen key-IV pair, there exists a non-dismissible probability that the produced keystream will be of relatively short period. More explicitly, a keystream of period. $2^{55}$ may appear with probability $2^{-71}$, and one can show the existence of at least one key-lV pair producing a period $2^{11}$ keystream.

This study aims to investigate the determinants of default risk of rural banks in East Java, Indonesia. The method used is descriptive verification and logistic regression analysis. The data used is secondary in the form of monthly annual financial reports of rural banks in East Java during the period 2009-2018. From the results, it was shown that net interest margin (NIM) as a proxy of market risk, non-performing loan (NPL) as a proxy of credit risk, operation efficiency as a proxy of operational risk and return on assets (ROA) as a proxy of profitability have a significant influence on default risk. Meanwhile, the loan to deposit (LDR) ratio as a proxy of liquidity risk has no significant influence on default risk. Banks need to implement risk management and meet the capital adequacy requirements of regulators so that they are resistant to risk, and also, compliant with bank governance to be able to produce high returns for rural banks have an impact on sustainability and its existence. The ability to identify setbacks in bank conditions and the ability to distinguish between healthy and problematic banks will enable to anticipate default banks.

The study investigates the existence of an optimal level of cash and the firm characteristics influencing the decision to hold cash, and the adjusting speed of the cash holdings to the target level. It highlights the heterogeneity of cash adjustment speed in the Vietnam market. The research employs the 417 samples of Vietnamese non - financial listed firms in the period of 2010 to 2019. The study uses the Pool OLS model, Fixed effect model (FEM), Random effect model (REM), and GMM model. According to the research findings, there is an optimal amount of cash at which the firm's value is maximized in Vietnamese listed firms, and the majority of the firms in the sample retain cash over the target level. Furthermore, the study demonstrates that firms actively modify their cash holdings to the optimal level with an adjustment speed of less than one owing to adjustment cost constraints. This speed varies between groupings of enterprises with different characteristics, underlining the heterogeneity of the adjustment speed even more. Small deviation firms adjust more rapidly than large deviation firms. Large free cash flow (FCF) firms adjust more readily than small FCF firms, and fiscal deficit firms modify more rapidly than firms with a financial surplus.
