Background: While the application of procedural methods to solve the infertility problem has increased, the decline in the quality of life of women who experience infertility has been disregarded. Methods: This qualitative study used phenomenological analysis of data collected from 13 women with infertility in South Korea to reveal the subjective meaning of physical experiences perceived by women over the course of treatment. Results: Upon analyses of the treatment experiences of women with infertility in South Korea via a phenomenological analysis method, 10 themes were extracted and integrated into four theme clusters ("Perceiving infertility," "The body that gives birth," "A process in an endless tunnel," "Caring for my marginalized identity"). Conclusion: The results of this study suggest that women with infertility in South Korea perceived their own bodies as givers of birth living in traditional and patriarchal societies. A contextual flow proceeded to the final stage of women caring for their marginalized identity, which had suffered throughout the course of their infertility journey.

At present, the smart grid has become one of the indispensable infrastructures in people's lives. As a commonly used communication method, wireless communication is gradually, being widely used in smart grid systems due to its convenient deployment and wide range of serious challenges to security. For the insecurity of the schemes based on large integer factorization and discrete logarithm problem in the quantum environment, an identity-based key management scheme for smart grid over lattice is proposed. To assure the communication security, through constructing intra-cluster and inter-cluster multi-hop routing secure mechanism. The time parameter and identity information are introduced in the relying phase. Through using the symmetric cryptography algorithm to encrypt improve communication efficiency. Through output the authentication information with probability, the protocol makes the private key of the certification body no relation with the distribution of authentication information. Theoretic studies and figures show that the efficiency of keys can be authenticated, so the number of attacks, including masquerade, reply and message manipulation attacks can be resisted. The new scheme can not only increase the security, but also decrease the communication energy consumption.

Waring's problem deals with representing any nonconstant function in a set of functions as a sum of kth powers of nonconstant functions in the same set. Consider ${\sum}_{i=1}^p\;f_i(z)^k=z$. Suppose that $k{\geq}2$. Let p be the smallest number of functions that give the above identity. We consider Waring's problem for the set of linear fractional transformations and obtain p = k.

The reference-class problem is known as a problem that frequentism on the nature of probability is supposed to encounter. Alan H$\acute{a}$jek argues that other theories on the nature of probability also meet this problem inevitably and claims that we can resolve the problem by regarding conditional probabilities as primitive. In this paper I shall present an adequate way of understanding the reference-class problem and its philosophical implications by scrutinizing his argument. H$\acute{a}$jek's claim is to be classified into the following two: (i) probability is relative to its reference class and (ii) what is known as the 'Ratio' analysis of conditional probability is wrong. H$\acute{a}$jek believes that these two are to be closely related but I believe these two should be separated. Moreover, I shall claim that we should accept the former but not the latter. Finally, regarding the identity condition of reference class I shall distinguish the extensional criterion from the non-extensional one. I shall claim that the non-extensional criterion is the right one for the identity condition of reference class by arguing that the reference-class problem should be regarded as an instance of the qua-problem.

The purposes of this study were to examine the influence of the self-identity, parenting style, peer attachment, and relationship with teacher on career identity, and to verify if self- identity shows the moderating effect in the relationship among the parenting style, peer attachment, relationship with teacher, and career identity of middle school students. The data of 3rd-year middle school students, from the 1st grade panel of 'Korea Children And Youth Panel Survey(KCYPS)' by National Youth Policy Institute, was used as the analysis data. The program which was used for the analysis was SPSS ver 22.0 for descriptive, Cronbach's α, and multiple regression analysis. The results of this study are as follows. First, it was revealed that the most influential variable for career identity was self identity, followed by peer attachment, while relationship with teacher is least influential. Parenting style did not have a direct effect on career identity. Second, it was revealed that self-identity had a moderating effect when the interaction between parenting style and the self-identity, and the interaction between relationship with teacher and the self-identity were injected. Therefore, if the education related to the self-identity is conducted continuously in the home economics subject, the conflict and anxiety on the career problem of middle school students will be reduced and the career identity will be developed more effectively.

If landscape is formed from quiet identity the place possesses, the problem of landscape in the garden Atlantique face the problem of the identity. Therefore, this study examined the identity of the garden Atlantique in the co-relationship between th garden and landscape. The garden 'Atlantique' was made on a rectangular slate roof at the Montparnasse station in Paris, France in 1994. The garden is bounded on all sides by the buildings of the mixed business and residential area that surround the station. Before the flat slate roof above the platform and parking structure was installed there was no garden. Because the slate roof area was the only area that the garden could be built, it was necessarily restricted in design and seems to have little or no visual relation to its surroundings. As two elements to understand the garden Atlantique, a recognition of esthetic system of landscape around and understanding of physical environment of the site are required. Therefore, this study tried to know how the physical elements of the garden makes the landscape in the relation with the environment and what kind of landscape can be seen in there through the poetics of landscape (une poetique du paysage) and the reculture (la reculture).

This study investigates an undergraduate student's environmental club experience by employing a biographical research method. The informant has been member of the environmental club since he is a freshman. The purpose of this study is three points. First, which theoretical framework is suitable to explain the characteristics of environmental club experience ? Second, what is the characteristics of the informant's environmental club experience analysed by means of the theoretical framework ? Finally, what is the educational meaning of environmental club experience ? As a result, I find that environmental identity is very powerful framework to explain the characteristics of environmental club experience. Also, I explain the informant's environmental club experience as the formation of environmental identity by changes in three aspects. In the informant's life, cultural world of environment/environmental movement becomes salient which is closely connected with development of agency in the world and understanding how environmental problems can be solved. It is argued that environmental club experience has educational meaning in the studies and practices of environmental education, as follows. Environmental club experience has implications of redefining the goals of environmental education, and improving environmental problem solving learning. Finally, the informant's environmental identity is considered as reflexive identity which is formed through personal reflection of his experience.

A convolution neural networks (CNNs) has demonstrated outstanding performance compared to other algorithms in the field of face recognition. Regarding the over-fitting problem of CNN, researchers have proposed a residual network to ease the training for recognition accuracy improvement. In this study, a novel face recognition model based on game theory for call-over in the classroom was proposed. In the proposed scheme, an image with multiple faces was used as input, and the residual network identified each face with a confidence score to form a list of student identities. Face tracking of the same identity or low confidence were determined to be the optimisation objective, with the game participants set formed from the student identity list. Game theory optimises the authentication strategy according to the confidence value and identity set to improve recognition accuracy. We observed that there exists an optimal mapping relation between face and identity to avoid multiple faces associated with one identity in the proposed scheme and that the proposed game-based scheme can reduce the error rate, as compared to the existing schemes with deeper neural network.

Certificate-based cryptography is a new cryptographic paradigm that provides an interesting balance between identity-based cryptography and traditional public key cryptography. It not only simplifies the complicated certificate management problem in traditional public key cryptography, but also eliminates the key escrow problem in identity-based cryptography. As an extension of the signcryption in certificate-based cryptography, certificate-based signcryption provides the functionalities of certificate-based encryption and certificate-based signature simultaneously. However, to the best of our knowledge, all constructions of certificate-based signcryption in the literature so far have to be based on the costly bilinear pairings. In this paper, we propose a certificate-based signcryption scheme that does not depend on the bilinear pairings. The proposed scheme is provably secure in the random oracle model. Due to avoiding the computationally-heavy paring operations, the proposed scheme significantly reduces the cost of computation and outperforms the previous certificate-based signcryption schemes.
