The present paper centers on the establishment of a quantified relationship between the macroscopic visual parameters of a Diesel spray and its most influential factors. The factors considered are the ambient gas density, as an external condition relative to the injection system, and nozzle hole diameter and injection pressure as internal ones. The main purpose of this work is to validate and extend the different correlations available in the literature to the present state of the Diesel engine, i.e. high injection pressure, small nozzle holes, severe cavitating conditions, etc. Five mono-orifice, axi-symmetrical nozzles with different diameters have been studied in two different test rigs from which one can reproduce solely the real engine in-cylinder air density, and the other, both the density and the pressure. A parametric study was carried out and it enabled the spray tip penetration to be expressed as a function of nozzle hole diameter, injection pressure and environment gas density. The temporal synchronization of the penetration and injection rate data revealed a possible explanation for the discontinuity observed as well by other authors in the spray's penetration law. The experimental results obtained from both test rigs have shown good agreement with the theoretical analysis. There have been observed small but consistent differences between the two test rigs regarding the spray penetration and cone angle, and thus an analysis of the possible causes for these differences has also been included.

Colin Rowe was an important historian, theorist and critic in Modern architecture. His significance in Modern architectural history lies in not only historiography which has changed our view of Modernism but deep theoretical involvement in practice. This study is a critical review and analysis on his formalist approach in Architecture. With a view that his position of formalist has indispensible relationship with liberalism from K. Popper's critical rationalism, this study try to show how his philosophical background has an influence upon his way of seeing architecture, history, form, urbanism, and meaning, etc. And this study also try to explain why the principle of architecture as an autonomous discipline which is the main point of view in Rowe's criticism has been so successful and influential. This study also explain what is the possibility and limitation of Rowe's formalist approach and way of reading buildings. His intelligent way of formal analysis can give us new understandings of how the form generates and the process of design goes on. Furthermore it guide us a new horizon of architecture as a language game. Since his early writings showed both side of formalist approach in architecture and it didn't changed a lot. We can understand his 'Collage City' was a his final answer to his formalist way of making architecture and urbanism. we can estemate it as a utopia without utopianism and an ideology without ideological color.

Objective: This study investigated the problems that could be faced with when engineers try to improve the affective quality using the DMAIC model. Background: Affective quality is considered one of the most influential factors for the competitive power of consumer products and many engineers make effort to improve the affective quality. Since the Six Sigma process is effective and wide-used method for quality improvement, it can also be used to improve the affective quality. However six sigma tools cannot be directly used for affective quality because of the subjective and qualitative characteristics of the human affection. Method: Investigate the goals, processes and key factors of DMAIC model and find the difficulties to use six sigma tools for the affective quality. Results: Most of the problems arise from measuring and quantifying the human affective response level and understanding the relationship between the human affective factors. Conclusion: Both the protocol for measuring human affection and the monitoring system to find the affective response change for the product or service are required. Application: The results of this study could be helpful for the engineers not specialized in ergonomics to improve the affective quality in systematic approach.

Purpose: This study was to assess relationships among the uncertainty, medical staff's support, and anxiety perceived by family members with cancer patients while the family members were waiting for their patients undergoing surgery. Method: The data were collected from the family members of cancer patients who were undergoing surgery in D University Hospital at B city from February 1 to April 12, 2005. The used instruments were the State Anxiety Scale of Spielberger's(1975) STAI, Mishel's Uncertainty in Illness Scale (MUIS)(1981), and Relationship Questionnaires (Lee, 1978). The collected data was analyzed by using t-test, ANOVA, Pearson's coefficients, and stepwise multiple regression. Results: As the result, the most influential variable explaining anxiety of family members was uncertainty $({\ss}=0.37)$, followed by perceived illness state $({\ss}=-0.27)$. These two variables simultaneously explained 29.3% of the variance in anxiety. Conclusion: We suggest to develop a nursing intervention program to reduce the uncertainty through the medical staff's support and o test its effects.
