In this review, the fabrication of silicon based memory capacitor and organic memory thin film transistors (TFTs) was discussed for their potential identification tag applications and biosensor applications. Metal or non-metal nanoparticles (NPs) could be capped with chemicals or biomolecules such as protein and oligo-DNA, and also be self-assembly monolayered on corresponding target biomolecules conjugated dielectric layers. The monolayered NPs were formed to be charging elements of a nano floating gate layer as forming organic memody deivces. In particular, the strong and selective binding events of the NPs through biomolecular interactions exhibited effective electrostatic phenomena in memory capacitors and TFTs formats. In addition, memory devices fabricated as organic thin film transistors (OTFTs) have been intensively introduced to facilitate organic electronics era on flexible substrates. The memory OTFTs could be applicable eventually to the development of new conceptual devices.

Decentralized Identity is based on the concept of self-sovereign identity, in which holders manage and provide their own credentials. However, a procedure is required to obtain credentials from issuers, and there is a risk of mess personal information leaking due to negligence of the issuers. In this paper, we propose a peer decentralized identity system based on Peer DID technology that allows only participants to verify their identity in 1:1 or 1:N small groups by matching the holder with the issuer. It is directly connected to a mobile device using short-range wireless communications such as bluetooth, and the holders create and provide their own credentials in person to the other party, thus fully realizing the self-sovereignty identity. The proposed system can simplify the identification process, improve security and privacy, and reduce costs. Furthermore, an extended architecture is possible to connect the proposed system and the distributed ledger to identify users in other domains. In the future, based on various technologies, it is also necessary to expand research on identity systems that can be utilized for human-to-thing and things-to-things authentication.

With the development of the Internet, user authentication technology that proves me online is improving. Existing ID methods pose a threat of personal information leakage if the service provider manages personal information and security is weak, and the information subject is to the service provider. In this study, as online identification technology develops, we propose a DID-based self-authentication model to prevent the threat of leakage of personal information from a centralized format and strengthen sovereignty. The proposed model allows users to directly manage personal information and strengthen their sovereignty over information topics through VC issued by the issuing agency. As a research method, a self-authentication model that guarantees security and integrity is presented using a decentralized identifier method based on distributed ledger technology, and the security of the attack method is analyzed. Because it authenticates through DID Auth using public key encryption algorithms, it is safe from sniffing, man in the middle attack, and the proposed model can replace real identity card.

This essay interprets envy not as a form of conventional conflict between women but as a type of common response of self-preservation focused on envy represented in the American film, Single White Female, and the Korean film, Female Teacher. Although envy is traditionally classified as a feminine emotion, it is an innate human emotion regardless of gender identity. Especially in the competitive era of neo-liberalism, we recognize only its negative side while overlooking its positive side as envy originates from comparison with others. Hedy's mimicking of Allie in Single White Female is not the same as idealized identification because her envy is aggressive and a self-assertive response while transforming Allie's identity. Likewise, envy of a protagonist in Female Teacher triggers an action of self-preservation against irrational social and personal inequality. Accordingly, a type of resistant and critical power resides in envy between women in these films. Therefore, proper recognition of repressed envy is required in order to prevent its transition towards a violent outcome.

Objectives of this study were to identify the hotspot for displacement of the on-line water quality sensors, in order to detect illicit discharge of untreated wastewater. A total of twenty-six water quality parameters were measured in sewer networks of the industrial complex located in Daejeon city as a test-bed site of this study. For the water qualities measured on a daily basis by 2-hour interval, the self-organizing maps(SOMs), one of the artificial neural networks(ANNs), were applied to classify the catchments to the clusters in accordance with patterns of water qualities discharged, and to determine the hotspot for priority sensor allocation in the study. The results revealed that the catchments were classified into four clusters in terms of extent of water qualities, in which the grouping were validated by the Euclidean distance and Davies-Bouldin index. Of the on-line sensors, total organic carbon(TOC) sensor, selected to be suitable for organic pollutants monitoring, would be effective to be allocated in D and a part of E catchments. Pb sensor, of heavy metals, would be suitable to be displaced in A and a part of B catchments.

In this paper, we developed a problem-solving based safety education program using physical computing for middle school students and applied it to verify the impact on self-efficacy and interest. The safety education program developed in this study includes four stages of the creative problem-solving model: problem identification, planning, implementation, and evaluation, and learning activities using Arduino, a physical computing tool. After implementing the education program with 77 third-year middle school students, both self-efficacy and interest of middle school students increased significantly. Based on the research results, the effectiveness of the safety education program that used physical computing and problem-solving steps was confirmed, and practical implications were presented to promote the activation of physical computing education in the school field.

As today's "ninth art", role-playing games recognized by most players due to their surreal themes and sustained reflection on social diseases. Through precise control of story-telling and game visuals, players develop an avatar identification during role-playing game. Based on Lacan's mirror stage theory, a new self-identity mechanism is established under the guidance of role-playing games. As a "player", the subject's interpretation of himself is shifted by the game order, and the subject identifies with the role-playing game while at the same time being structured by the desire of role-playing game. The immersive experience and emotional guidance of role-playing games all point to the most instinctive human desires. The psychoanalytic theory from Lacan's perspective explains the source of players' desire, and the expression of players' desire in the game. It also plays an important role in the emotional rendering and identity aspects of role-playing games. This paper is to establish that role-playing games do have an impact on the player's self-identity through a Lacanian psychoanalytic reading of role-playing games.

Background: The evolving healthcare environment necessitates changes in pharmacy education to meet these demands, with problem-based learning (PBL) being a promising approach. Methods: This study employed a single-group, repeated-measures design to evaluate the effects of PBL on the communication and problem-solving skills of fifth-year pharmacy students at S University. The course, which focused on pharmacy practice and communication, included 36 students who participated in structured pre- and post-intervention surveys, as well as self-reflection journals. The primary competencies assessed were problem-solving and communication skills. Data collection involved quantitative measures through surveys and qualitative insights from self-reflection notes. Results: Of the 36 students, 35 completed the pre-intervention surveys, and 27 completed the post-intervention assessments. Significant improvements were observed in problem-solving skills, including problem identification, information gathering, and planning. Communication skills showed overall improvement, though the differences were not statistically significant. Qualitative analysis of self-reflection notes revealed enhanced understanding of elderly patient care, increased responsibility, teamwork, and the importance of effective communication in pharmacy practice. Commonly identified themes included a heightened sense of responsibility, the importance of teamwork, and an appreciation for the multifaceted nature of pharmacy practice in elderly care. Conclusion: The PBL approach effectively enhanced students' problem-solving abilities and provided valuable experiential learning in pharmacy practice. The qualitative data indicated that students gained a deeper understanding of their roles and responsibilities, fostering greater motivation and teamwork. Further research should focus on broader applications across different institutions to validate these findings.
