In this paper, $Ba_{0.5}$Sr$_{0.5}$TiO$_3$ thin films were prepared on Pt/Ti/SiO$_2$/Si substrate by RF magnetron sputtering method. We investigated effect of deposition conditions (especially RF input power) on structural properties of BST thin films. Deposit conditions of BST films were set working gas ratio, Ar:O$_2$= 70 : 30, working pressure 10mTorr, and RF input power 25W, 50W, 75W and 100W. Post-annealing using rapid thermal annealing(RTA) performed at 45$0^{\circ}C$, 55$0^{\circ}C$, $650^{\circ}C$, and 75$0^{\circ}C$ in oxigen ambient for 60 sec, respectively. The structural properties of BST films on Pt/Ti/SiO$_2$/Si substrate analysed by X-ray diffraction(XRD).).).

Exploitation of renewable energies is on the increase to mitigate the reliance on fossil fuels and other natural gases with rocketing prices currently due to the depletion of their reserves not to mention their diverse consequences on the environment. Divergently, there are lots of industries "throwing" heat at higher temperatures as by products into the environment. This waste heat can be recovered through organic Rankine systems and converted to electrical energy with a waste heat recovery organic Rankine cycle system (WHR-ORC). This study uses the annual average condenser effluent from Namhae power plant as heat source and surface seawater as cooling source to analyze a waste heat recovery organic Rankine cycle using the Aspen HYSYS simulation software package. Hydrocarbon mixtures are employed as working fluid and varied in a ratio of 9:1. Results indicate that Pentane/Isobutane (90/10) mixture is the favorable working fluid for optimizing the waste heat recovery organic Rankine cycle at the set simulation conditions.

This study with emphasis on protecting human rights of people with mental disorder investigated human rights awareness among mental health workers and identify factors affecting their awareness. Questionnaires were sent out to employees working in mental health facilities in all parts of the country and of those 1094 were used to analyze. According to the analysis, employees' human rights awareness was ranked highest in the areas of occupational therapy and lowest in the areas of admission and discharge. Those who are women, aged between 30 and 40, highly educated, with long tenure, employed as social workers and working at rehabilitation programs presented high awareness of human rights so did employees with license in mental health and training experience in human rights. The result also presented negative correlation between employees' human rights awareness and their prejudice against people with mental disorder. Through this study, guidelines will be set up to help employees acknowledge the importance of human rights awareness and raise their awareness to promote and practice human rights of people with mental disorder.

This study aims to determine the availability of forensic accounting application factors sought by auditors' representatives of Jordanian Certified Public Accounting and auditors working in the Audit Bureau. The study identifies as well the role of these application factors in enhancing the efficiency of auditors due to the increased responsibility on them in the face of various fraud cases on the one hand, and their appearance in the courts as financial experts supporting the judiciary to adjudicate financial cases on the other hand. To achieve the objectives of the study, the researchers used the descriptive analytical method because of its suitability for the nature of the research. The population of the study consisted of 433 Jordanian certified public accountants and 520 auditors working in the Audit Bureau, from which a sample of 426 was constructed. A questionnaire was developed to collect data and the Statistical Package for Social Sciences was utilized to analyze data and test hypotheses. The study found that there is a statistical difference between the responses of the two samples of the study, and it concluded a set of recommendations, which are hoped to help legislators in strengthening and developing the forensic accounting profession in Jordan.

The measurement of the key product quality index plays an important role in improving the production efficiency and ensuring the safety of the enterprise. Since the actual working conditions and parameters will inevitably change to some extent with time, such as drift of working point, wear of equipment and temperature change, etc., these will lead to the degradation of the quality variable prediction model. To deal with this problem, the selective integrated moving windows based principal component regression (SIMV-PCR) is proposed in this study. In the algorithm of traditional moving window, only the latest local process information is used, and the global process information will not be enough. In order to make full use of the process information contained in the past windows, a set of local models with differences are selected through hypothesis testing theory. The significance levels of both T - test and χ² - test are used to judge whether there is identity between two local models. Then the models are integrated by Bayesian quality estimation to improve the accuracy of quality variable prediction. The effectiveness of the proposed adaptive soft measurement method is verified by a numerical example and a practical industrial process.

다중나무예측치들이 한 개의 나무 예측치 보다 검증용 자료 오분류률을 줄이는데 있어서 더 정확하다 라는 것은 잘 알려져 있는 사실이다. 다중나무를 생성하는 두 가지 방법이 있다. 하나는 원래의 훈련용 자료를 재 추출하여 수정된 훈련용자료들을 만든 다음에 각각의 수정된 훈련용 자료에 근거하여 나무를 만드는 것이다. arcing 알고리즘이 효율적이라고 알려져있다. 다른 방법은 각각의 마디에서 최적 분리의 후보들 중에서 랜덤하게 하나를 선택하여 나무를 생성하는데에, 이 과정을 반복하면 원래의 훈련용 자료에 대해서 비교적 좋은 나무들을 생성하리라 기대되다. 우리는 arcing의 각 단계에서 후자의 다중회귀나무예측치들을 사용하는 결합다중회귀나무예측치를 제안하고, 효능 있는 화합물들을 찾기 위한 고속의 대량 선별 자료 분석의 예를 통해서 예측방법들의 효율성을 비교한다.

본 연구에서는 리더십이 조직유효성에 어떤 과정을 거쳐서 영향을 미치는지 알아보고자, 변혁적 리더십의 하위요인들을 독립변수로 놓고, 조직유효성의 하위요인들을 종속변수로 설정하면서, 조직(직장)에서 가장 중요한 사람과 일에 대한 관계 중 리더에 대한 조직구성원의 관계를 신뢰로 설정하고 조직구성원과 일의 관계를 자기효능감으로 설정하면서 이 두 요소가 어떻게 작용을 하는지 조사하였다. 검증 결과 독립 변수들의 하위요인들 모두가 신뢰에 영향을 주었고, 그 신뢰는 조직유효성에 정의 영향을 미치고 있었다. 그러나 변혁적 리더십의 모든 하위요인들은 자기효능감에는 유의한 영향을 주지 못하였다. 그러나 신뢰가 자기효능감에 영향을 주었고, 그 결과 자기효능감은 조직유효성의 모든 하위요인들에 정의 영향을 미치는 것으로 분석되었다.

Background: Messaging surrounding skin cancer prevention has previously focused on the general public and emphasized how or when activities should be undertaken to reduce solar ultraviolet radiation (UVR) exposure. Generic messages may not be applicable to all settings, and should be tailored to protect unique and/or highly susceptible subpopulations, such as outdoor workers. The primary objective of this study was to develop a set of tailored, practical, harm-reducing sun safety messages that will better support outdoor workers and their employers in reducing the risk of solar UVR exposure and UVR-related occupational illnesses. Methods: We adapted a core set of sun safety messages previously developed for the general population to be more applicable and actionable by outdoor workers and their employers. This study used an integrated knowledge translation approach and a modified Delphi method (which uses a survey-based consensus process) to tailor the established set of sun safety messages for use for outdoor worker populations. Results: The tailored messages were created with a consideration for what is feasible for outdoor workers, and provide users with key facts, recommendations, and tips related to preventing skin cancer, eye damage, and heat stress, specifically when working outdoors. Conclusion: The resulting tailored messages are a set of evidence-based, expert- approved, and stakeholder-workshopped messages that can be used in a variety of work settings as part of an exposure control plan for employers with outdoor workers.
