The purpose of this study is to examine the influence of the leisure constraint of a private security guard on his/her task stress and life satisfaction. The subjects of this study were chosen among the private security guards working in Seoul based private security firms in 2009, and by going through judgement sampling, 300 cases were applied in the final analysis. Collected data went through factor analysis, reliability analysis, regression analysis, and path analysis by using SPSSWIN 17.0. In reference with the reliability of the questionnaire, Cronbach's $\alpha$ was over .600. The conclusion of this study is as following. Firstly, the leisure constraint of a private security guard affects his/her task stress. In other words, when peripheral and individual constraint increase, task stress is intensified, while task stress winds down when interpersonal constraint decreases. Secondly, the leisure constraint of a private security guard affects life satisfaction. That is, when individual constraint goes down, life satisfaction is improved. Thirdly, the task stress of a private security guard affects life satisfaction. when compensation and career development increase, life satisfaction rises. On the other hand when task characteristic is weakened, life satisfaction gets lower. Fourthly, the leisure constraint of a private security guard has a causal influence on task stress and life satisfaction. Accordingly, it becomes apparent that the task stress is a significant variable which intermediates the relation between leisure constraint and life satisfaction.

Health information systems (HIS) are facing security challenges on data privacy and confidentiality. These challenges are based on centralized system architecture creating a target for malicious attacks. Blockchain technology has emerged as a trending technology with the potential to improve data security. Despite the effectiveness of this technology, still HIS are suffering from a lack of data privacy and confidentiality. This paper presents a blockchain-based data storage security architecture integrated with an e-Health care system to improve its security. The study employed a qualitative research method where data were collected using interviews and document analysis. Execute-order-validate Fabric's storage security architecture was implemented through private data collection, which is the combination of the actual private data stored in a private state, and a hash of that private data to guarantee data privacy. The key findings of this research show that data privacy and confidentiality are attained through a private data policy. Network peers are decentralized with blockchain only for hash storage to avoid storage challenges. Cost-effectiveness is achieved through data storage within a database of a Hyperledger Fabric. The overall performance of Fabric is higher than Ethereum. Ethereum's low performance is due to its execute-validate architecture which has high computation power with transaction inconsistencies. E-Health care system administrators should be trained and engaged with blockchain architectural designs for health data storage security. Health policymakers should be aware of blockchain technology and make use of the findings. The scientific contribution of this study is based on; cost-effectiveness of secured data storage, the use of hashes of network data stored in each node, and low energy consumption of Fabric leading to high performance.

The main challenge in building efficient broadcast systems is to encrypt messages with short ciphertexts. In this paper, we present a new construction based on the identity. Our construction contains the desirable features, such as constant size ciphertexts and private keys, short public keys and not fixing the total number of possible users in the setup. In addition, the proposed scheme achieves the full security which is stronger than the selective-identity security. Furthermore we show that the proof of security does not rely on the random oracles. To the best our knowledge, it is the first efficient scheme that is full security and achieves constant size ciphertexts and private keys which solve the trade-off between the ciphertext size and the private key size.
