This paper examines the relationship and ideas of Hannah Arendt and Philip Roth including how they met, their correspondence and intellectual parallels, particularly in their shared criticism of Jewish ideals and culture in Europe and North America. It analyzes similarities in their careers and texts, especially between Eichmann in Jerusalem and Operation Shylock, as well as The Ghost Writer, while measuring their reception as social commentators and writers. Kafka was an important figure for both writers, Arendt's earliest writing engaged with the significance of Kafka in understanding and criticizing twentieth century political and cultural values in Europe. For Roth, Kafka offered a similar critique of moral principles he found corroded in North American Jewish life. Arendt connected with other writers, notably Isak Dinesen, W. H. Auden, Randall Jarrell and William Styron who further linked the two: he knew both Arendt and Roth and cited, incorrectly, a work by Arendt as the source for the key incident in his 1979 novel Sophie's Choice. He claimed it was Eichmann in Jerusalem; it was Arendt's The Origins of Totalitarianism. Arendt's reaction to Roth's fiction, however, remains a mystery: she died in 1975, before Roth began to seriously and consistently engage with Holocaust issues in works like The Ghost Writer (1979) and Operation Shylock (1993). Yet even in death they are joined. Their graves are only steps apart at the Bard College Cemetery in Annandale-on-Hudson, New York.

Purpose : The aim of this study was to explore the attributes, antecedents, and consequences of patient-centered care (PCC) for older adults with multimorbidity in acute care hospitals. Methods : The concept analysis performed by Walker and Avant was used to analyze PCC. Fifteen studies from the literature related to PCC appear in systematic literature reviews in the fields of theology, medicine, psychology, and nursing. Results : PCC in acute care hospitals was defined according to the five attributes of 'maintaining patient autonomy', 'empowering self-care', 'individualized and relationship-based care', 'shared decision-making', and 'creating a homelike environment'. Antecedents of PCC were found to be a respect for patients' preferences, qualifications of the nursing staff, care coordination and integration, and organizational support. Consequences of effective PCC were a functional status; health-related quality of life; satisfaction with care, mortality, and medical costs from the perspective of the patient and family; and quality of care and therapeutic relationships from nurses' viewpoints. Conclusion : PCC as defined by the results of this study will contribute to the foundation of institutionalization and the creation of a safe and healthy acute care hospital culture focused on patients' preferences and values.

The growth of mobile technology particularly smartphone applications such as ticketing, access control, and making payments are on the increase. Elliptic Curve Cryptography (ECC)-based systems have also become widely available in the market offering various convenient services by bringing smartphones in proximity to ECC-enabled objects. When a system user attempts to establish a connection, the AIK sends hashes to a server that then verifies the values. ECC can be used with various operating systems in conjunction with other technologies such as biometric verification systems, smart cards, anti-virus programs, and firewalls. The use of Elliptic-curve cryptography ensures efficient verification and signing of security status verification reports which allows the system to take advantage of Trusted Computing Technologies. This paper proposes a device payment method based on ECC and Shuffling based on distributed key exchange. Our study focuses on the secure and efficient implementation of ECC in payment device. This novel approach is well secure against intruders and will prevent the unauthorized extraction of information from communication. It converts plaintext into ASCII value that leads to the point of curve, then after, it performs shuffling to encrypt and decrypt the data to generate secret shared key used by both sender and receiver.

Lamport 일회용 패스워드(OTP)는 고정된 패스워드 그리고 패스워드의 사전공유라는 단순 패스워드가 지니는 문제점을 해결하기 위해 해시체인에 기반을 두고 있다. 하지만 Lamport 방식은 길이가 유한한 해시체인의 해시값을 OTP로 사용하기 때문에 해시체인을 구성하는 해시값들을 모두 소진한 이후에는 새로운 해시체인의 루트 해시값을 재 등록해야 한다는 단점을 가지고 있다. 이 같은 단점을 해결하기 위해 여러 연구가 진행되었으나 증명자와 검증자에 대한 계산 부담이 증가하는 등 새로운 단점이 노출되었다. 따라서 본 논문에서는 Lamport 방식의 장점을 유지하면서 동시에 단점을 해결하기 위해 기존 Lamport 방식 OTP의 핵심인 하나의 긴 해시체인 대신에 여러 개의 짧은 해시체인을 중첩 구성하는 새로운 방식의 OTP를 제안하고 비교 분석한다.

안전한 RFID 시스템을 위하여 현재까지 다수의 RFID 인증 프로토콜이 제안되었다. 이들은 어떤 암호학적 요소를 사용하느냐에 따라 크게 해시기반, 재 암호화 기반, XOR 기반으로 나눌 수 있다. 현재까지 알려진 대표적인 공격으로는 도청, 사칭, 위치추적공격 등이 있는데 기존에 제안된 프로토콜들은 이러한 공격에 안전하지 않거나, 데이터베이스의 태그 검색과정이 비효율적이었다. 따라서 본 논문에서는 해시함수를 사용하여 알려진 공격에 안전하고 데이터베이스가 태그와 사전에 공유한 값을 통해 이전 세션의 상태를 파악하게 하여 태그 검색 과정이 비교적 간단한 프로토콜을 제안한다.

We propose a new approach called PESA (Prioritized replay Evolutionary and Swarm Algorithms) combining prioritized replay of reinforcement learning with hybrid evolutionary algorithms. PESA hybridizes different evolutionary and swarm algorithms such as particle swarm optimization, evolution strategies, simulated annealing, and differential evolution, with a modular approach to account for other algorithms. PESA hybridizes three algorithms by storing their solutions in a shared replay memory, then applying prioritized replay to redistribute data between the integral algorithms in frequent form based on their fitness and priority values, which significantly enhances sample diversity and algorithm exploration. Additionally, greedy replay is used implicitly to improve PESA exploitation close to the end of evolution. PESA features in balancing exploration and exploitation during search and the parallel computing result in an agnostic excellent performance over a wide range of experiments and problems presented in this work. PESA also shows very good scalability with number of processors in solving an expensive problem of optimizing nuclear fuel in nuclear power plants. PESA's competitive performance and modularity over all experiments allow it to join the family of evolutionary algorithms as a new hybrid algorithm; unleashing the power of parallel computing for expensive optimization.

Purpose - This paper finds the repurchase intentions of customers in a sharing economy via Airbnb and Uber, which are classic sharing-economy service businesses. Design/methodology - This paper analyzes sharing economy effects using variables in a structural equation model. Findings - We verified that values have a significant effect on the trust in a platform. We also verified that the effects that value propositions have on repurchase intention are significant. Research Limitations/Implications - First, there may be some distinction between men and women with regard to divided trust. Second, if commitment is divided into commitment to the host and commitment to the platform, as is the case for trust, the results will not be as expected. Third, if results could be categorized by nationality after gathering more samples, each nationality might have different opinions about these factors. Finally, the sharing economy can be identified and analyzed for various industries, such as space, transportation, and service. At this point, it is inconvenient to not have more implications. Originality/value - This study focuses on the repurchase intentions of customers. Unlike earlier studies, it is meaningful that trust is divided between the host and the platform, and that it can be analyzed. It is also important to establish the relationship between trust and commitment, and the relationship toward repurchasing in the shared-economy.

최근 공유가치창출(CSV: Creating Shared Value)이 초미의 관심을 끌고 있다. 이는 기존의 기업의 사회적 책임(CSR: Corporate Social Responsibility) 성과에 사회적 경제적 가치창출이라는 사회적 문제해결의 대안이 될 수 있다는 시각이 작용하기 때문이다. CSR과 CSV의 성과를 구분하여 확인하기는 어려움이 있다. 따라서 CSV 성과에 대한 실증분석 기법의 개발과 소비자의 CSV에 대한 인식 및 태도가 검증될 수 있는 방법론의 개발이 필요하다. 기업은 가치사슬의 혁신을 통한 사회문제의 해결과 더불어 경쟁우위를 점할 수 있어야 한다. 진일보한 CSV 논의가 필요한 시점으로 파악하는 까닭은 아직 CSV가 초기 연구 단계에 머물러 있는 실정이기 때문이다. 이에 본 연구는 우선적으로 CSV 의의와 필요한 배경, 기업의 사회적 책임(CSR)과 공유가치창출(CSV)의 상호비교 분석을 하였다. 더 나아가 CSV의 기존 연구의 범위가 매우 협소했던 한계점을 넘어 가치사슬에서 CSV의 필요성을 피력하고자 한다. 오늘날 다수의 기업들은 기업의 사회적 책임을 수행하기 위한 노력을 기울여 왔다. 그러나 기업의 지속성장성 측면에서 단순히 CSR의 충족만으로는 수익창출을 위한 비즈니스모델로써는 한계가 있음이 지적되었다. 하나의 대안으로 최근 공유가치창출 도입의 필요성이 제기되고 있는 것이다. 선행연구를 통해 가치사슬관점의 CSV를 경제적 사회적 문화적 가치가 기업이미지 및 기업신뢰도를 매개로 구매의도로 이어지는 인과관계를 실증분석을 통해 밝혀 보았으며 구체적인 연구 결과는 다음과 같다. 첫째, 사회적 가치와 문화적 가치는 기업이미지에 긍정적 영향을 미치는 것으로 나타났다. 이는 CSV 활동을 통하여 소비자들이 해당 기업에 좋은 인상을 가질 수 있도록 하는 단초가 됨을 시사한다. 둘째, 사회적가치는 기업신뢰도에 긍정적 영향을 미치는 것으로 파악되었다. 따라서 CSV가 기업의 비용으로만 인식되는 것이 아닌 미래의 발전과 더불어 상생의 대안이 될 수 있다는 관점으로 접근해 나가야 할 것이다. 셋째, 기업이미지와 기업신뢰도 모두 구매의도에 영향을 미치는 것으로 나타났다. CSV 활동을 통해 기업에 대한 호의적인 평가를 유도할 수 있다는 관점에서 기업의 최종 목표인 지속적 이익창출과 연계된다는 것을 감안하여 중장기적 전략으로 접근할 필요성이 있다고 판단된다.

Since the experience of major landscape change during last half of the century due to war and rapid urbanization, the traditional character has been weakened, and it is necessary for a reconsideration to improve the landscape for the future. To review these relationships, the importance of a comprehensive understanding of nature has been suggested. Therefore identification of a new concept based on the 'socio-cultural influence of landscape' and 'sense of place' which are related to peoples' previous experience, is required. Furthermore more practical definitions and criteria to reveal the relationship are necessary. Among the terms suggested to describe sense of place such as 'home', 'place identity', 'place-based meaning' and 'settlement identity' etc., the 'home' is selected to represent our surrounding landscape. For more practical classification of home landscape, additional terms are suggested and defined based on both the relationships between human beings and nature, and between memory derived from previous experience and shared values with in the community. The additional terms which are the most important in the role of landscape character related to humans' are; ⅰ) Personal Landscape: Landscape of an individual human, which derives from previous personal experience; involves distinguishable character for a given person, and it is emotional and flexible depending on circumstances. ⅱ) Ordinary Landscape： Landscape of the 'common interest' between members of a community, which is acceptable as a surrounding for everyday daily life, it produces the richness and variety of landscape. ⅲ) Kernel Landscape： Landscape of the 'common ground' which is acceptable to the majority members of the community, and it provides variety and stability for periods of time, and it could strongly represent community attitudes toward nature. ⅳ) Prototype Landscape: Landscape as the 'common denominator' of overall community from past to present and towards the future, which encompasses all the kernel landscape throughout history. It provides a sense of place, balances the homogeneity of character throughout overall communities. Some part of this can be shared throughout history to shape an overall sense of place. It can also represent short terms fashions. For a prototype landscape to reveal sense of place, there are a couple of points which we should underline the commencing point. Firstly, understanding the relationship between humans and nature should be based on a given character of surroundings. Secondly, reoccurring landscape elements which have sustained in history can lead to sense of place, and should be reviewed the influences between nature and humans.
