This article reviews the art and practice of strategic management process in hospitals today, in order to help hospital administrators for managing strategic management system in their hospitals. The strategic management process model in this article is based on an integrated approach combining traditional environmental model with resource-based model of strategy. The components of the model are consisted of five steps: (1)formulating objectives, strategic assessment by external environmental analysis, internal capability analysis, TOWS analysis and marketing audit, (3)strategy choice considering context and criteria of choice, (4)program implementation through operational planning, resource allocation, and conversion, and (5)control by monitoring and evaluating hospital outputs. This article deals with many aspects of issues inherent in every step on this strategic management process.

STEAM education is a topic-based curriculum to integrate the concepts into other subjects such as science, technology, engineering, art and mathematics in order to improve the students' interesting, understanding, integrated thinking and problem solving ability. In this paper, we designed STEAM curriculum in the form of Project-based Learning and developed the material for elementary students. We also developed the android-based application through searching for a utilization of IT simulation for enhancement the students' Project-based Learning effect.

The importance of avionics systems has increased to a significant level in modern aircraft development. Modern avionics system is a complex integrated system of state-of-art hardware and software technology. Specifying the avionics system architecture is the most important task throughout the avionics system design process. This paper reviews modern avionics system architectures and proposes an effective avionics architecture suitable for modern attack helicopters.

A satisfiability problem in propositional logic is the problem of checking for the existence of a set of truth values of atomic prepositions that renders an input propositional formula true. This paper describes an empirical investigation of a particular integer programming approach, using the set covering model, to solve satisfiability problems. Our satisfiability engine, SETSAT, is a fully integrated, linear programming based, branch and bound method using various symbolic routines for the reduction of the logic formulas. SETSAT has been implemented in the integer programming shell MINTO which, in turn, uses the CPLEX linear programming system. The logic processing routines were written in C and integrated into the MINTO functions. The experiments were conducted on a benchmark set of satisfiability problems that were compiled at the University of Ulm in Germany. The computational results indicate that our approach is competitive with the state of the art.

This paper presents a new soft switching dc-to-dc converter that employs IM transformer. Detailed analysis and design considerations of the proposed circuits are presented. By applying the proposed magnetic integration procedure, new integrated magnetic circuits featuring low loss, simple structure are then developed to overcome the limitations of prior art. Consequently, the power loss and the size of the integrated magnetic device are greatly reduced. The operation and performance of the proposed converter are demonstrated with an experimental converter that delivers a 5V/5A output from a 48V input at the maximum efficiency of 90 %.

Since the words and words in Chinese sentences are continuous and the length of vocabulary is huge, Chinese NER(Named Entity Recognition) always based on character representation. In recent years, many Chinese research has been reconsidered how to integrate the word information into the Chinese NER model. However, the traditional sequence model has complex structure, the slow inference speed, and an additional dictionary information is needed, which is difficult to implement in the industry. The approach in this paper has the state of the art and parallelizable, which is integrated the char-word embeddings, so that the model learns word information. The proposed model is easy to implement, and outperforms traditional model in terms of speed and efficiency, which is improved f1-score on two dataset.

This study intended to analyze science-arts integration activities in science textbook and explore the artistic elements of science-art integrated activities. For this purpose, we selected science-arts integration activities in elementary science textbooks of Korea by revised curriculum in 2007. We analyzed them by the type, the function and the role of arts. The analysis of artistic element was based on 'design element' suggested by Baron & Eisner. Results revealed that the science-arts integration activities were using a visual art form than any other and the role of arts was mainly to apply science concepts. Through the artistic element analysis, we found that most activities were emphasized on 'empathic understanding' category than other categories. Based on the results, science-arts integration activities with more diverse form of art should be developed. Also the artistic element should be considered in developing future science-arts integration activities.

This presentation will focus on computational materials research carried out across length scales. Examples will be presented that illustrate the way in which state-of-the-art quantum mechanical calculations and atomistic simulations can be applied to explain experimental data, design new structures, determine mechanisms, and enable new investigations. In particular, the presentation will present key findings from an integrated experimental and computational investigation of the tribological properties of polytetrafluoroethylene and its composites and predictions regarding the mechanical and tribological properties of inorganic nanostructured materials.

1950년에 최초의 상용 컴퓨터가 도입된 이래 컴퓨터는 모든 사회 분야에 있 어서 필수 불가결한 도구가 되었고 현대의 산업 사회는 정보산업사회라고 할 만큼 정보의 신속한 획득과 정보의 보유량은 산업 경쟁력의 핵심이 되고 있다. 용접 분야 에서도 적절한 용접 정보의 신속한 제공이 용접의 품질과 생산성 향상의 관건이 되고 있으며 최근 용접의 자동화가 급속히 이루어지고 컴퓨터에 의한 통합생산시스템(CIMS, Computer Integrated Manufacturing System)의 구축이 화발해짐에 따라 그들의 핵심 요소의 한 부분으로서 용접 정보처리 시스템의 역활과 중요성은 더욱 커지고 있다.
