The trade-off studies in the concept development stage to assess the relative goodness of alternative systems concepts for AE (architect engineering) design for the Barge Mounted SMR (BMSMR) is introduced. With respect to design margin, system performance, schedule and risk, the design selection is cond ucted using the following characteristics; barge mobility, system safety under the natural disaster (seismic), power output, interfacing with the other system, and the additional supporting functions as desalination. There are three findings that should be remedied; deficiencies in the assumed characteristics of the system being modeled, deficiencies in the test model, and excessively stringent system requirements. This study is performed using systems engineering approach with trade off matrix method. In order to execute this work, concept development stage is divided into three (3) phases as NA (needs analysis), CE (concept exploration), and CD (concept definition).

Purpose: The purpose of this study was to develop and test a structural model on cardiovascular disease risk factors among male manufacturing workers. Methods: Data were collected through questionnaires and health exams from 201 workers in a local electronic company during September 2004. Data analysis was done with SAS 9.1 for descriptive statistics and PC-LISREL 8.54 for covariance structural analysis Results: The overall fit of the hypothetical model to the data was moderate, it was modified by deleting five paths. The modified model had a better fit to the data($x^2=504.23$(p<001, df: 180), $x^2/df=2.80$, GFI=.95, RMR=.07, NFI=.90, PGFI=.64). Health behaviors and psychosocial distress were found to have significant direct effects on the cardiovascular disease risk factors. Self-concept had direct effect on psychosocial distress or health behaviors. Self-concept, work environment, and work condition had direct effect on social support. Work environment had indirect effect on psychosocial distress. Social support had indirect effect on health behaviors. But work environment and work condition were found to have little direct effect on health behaviors, psychosocial distress or cardiovascular disease risk factors. Conclusion: A cardiovascular health promotion program should therefore include psycho-social factors as well as health behavioral determinants in worksites.

The goal of the research is to identify the relationship between organizational justice, job satisfaction, and work attitudes in the context of job rotation. The competence and loyalty of the employees of an organization are critical to the organization's success. Therefore, organization should invest in developing their employees, including creating effective procedures and human resource management policies. A job rotation program is one of the critical policies in developing employees, as through this program employees can develop and actualize their abilities. However, there are some challenges in practice regarding implementing the procedures of job rotation. One of the challenges is related to the concept of organizational justice, which then impacts on employees' job satisfaction and work attitudes. This study was conducted in focused group discussions. The sample is 272 of a state-owned organization. In this study, the concept of organizational justice, with the dimensions of distributive justice, procedural justice, and interactional justice, were used along with the discussion of job satisfaction and other work attitudes. The results were issues of fairness in perceiving organizational justice in the job rotation context, and the most significant response lies in procedural justice.

The potential work is defined as the maximum available work extractable from a composite system. It is important concept to understand the behavior of a composite system because it is a property of the composite system and shows the possible room for the system to change its state by itself. To explain this concept quantitatively, the behavior of a composite system composed of two simple ideal gas systems is analyzed. The potential work of the composite system is estimated, the various reversible processes from a given state to the equilibrium state and the processes on which potential works are constant are shown on the T-P and S-V planes. Such an effort will be necessary to understand and characteristics of composite systems as well as helpful for a deeper comprehension of the energy conversion principles.

본 연구의 목적은 의학교육에서의 행복과 관련된 교육과정 도입을 탐색하기 위하여 의학전문대학원생들이 행복을 느끼는 활동 및 행복에 대한 개념 인식구조의 사전-사후변화를 분석하였다. 연구대상은 의학전문대학원에 재학 중인 2학년 학생 총 36명이었고, 일상재구성법과 네트워크분석을 사용하였다. 연구결과, 의학전문대학원생들은 먹기/대화하기, 여가활동을 하면서 행복을 많이 경험하고 있는 반면 학습활동을 통한 행복을 느끼는 빈도는 낮게 나타났다. 사전-사후의 행복을 표현하는 단어들은 많은 부분 유사하였고, 사전에는 '경제', 사후에는 '일'이 가장 높은 연결정도중심성을 나타냈다. 행복에 대한 개념의 구조가 1개 그룹에서 자신의 일, 가족의 건강, 삶에 대한 가치, 긍정적인 자아 등의 4개 그룹으로 나누어져 행복에 대한 개념이 피상적인 행복에 대한 개념에서 실제적인 행복에 대한 개념으로 인식이 변화하였다. 따라서 인간의 건강을 다룰 예비의사들이 행복에 대한 개념과 가치 등을 바르게 정립할 수 있도록 행복에 대한 의도적인 교육이 도입되어야 하고, 이를 위해서 행복과 관련된 교육과정이 체계적으로 개발되어야 할 것이다.

This work presents a concept and the related analysis of the traffic performance for a wireless broadband system based on fixed relay stations acting as wireless bridges. The analysis focuses on the important performance indicators end-to-end throughput and delay, taking into account the effects of an automated repeat request protocol. An extension to a MAC frame based access protocol like IEEE 802.11e, 802.15.3, 802.16a, and HIPERLAN2 is outlined and taken as basis for the calculations. The system is intended for both dense populated areas as an overlay to cellular radio systems and to provide wide-area broad-band coverage. The two possible deployment scenarios for both dense urban and wide-area environments are introduced. Analytical and validating simulation results are shown, proving the suitability of the proposed concept for both of the mentioned scenarios. It is established that the fixed relaying concept is well suited to substantially contribute to provide high capacity cellular broad-band radio coverage in next generation (NG) cellular wireless broadband systems.

Many previous research studies on extractive text summarization consider a subset of words in a document as keywords and use a sentence ranking function that ranks sentences based on their similarities with the list of extracted keywords. But the use of key concepts in automatic text summarization task has received less attention in literature on summarization. The proposed work uses key concepts identified from a document for creating a summary of the document. We view single-word or multi-word keyphrases of a document as the important concepts that a document elaborates on. Our work is based on the hypothesis that an extract is an elaboration of the important concepts to some permissible extent and it is controlled by the given summary length restriction. In other words, our method of text summarization chooses a subset of sentences from a document that maximizes the important concepts in the final summary. To allow diverse information in the summary, for each important concept, we select one sentence that is the best possible elaboration of the concept. Accordingly, the most important concept will contribute first to the summary, then to the second best concept, and so on. To prove the effectiveness of our proposed summarization method, we have compared it to some state-of-the art summarization systems and the results show that the proposed method outperforms the existing systems to which it is compared.
