1995 년부터 시작된 한국적 품질경영활동인 100PPM 품질혁신운동을 뒤돌아보고 21 세기 새로운 시대의 사회경제적 요건에 적합한 품질혁신활동으로 거듭나기 위해 설정된 완전제품화운동이 Single-PPM 품질혁신이다. Single-PPM 품질혁신은 1987년 모토롤라에서 개발되어 미국 내 많은 기업에서 도입, 전개되고 있는 6 시그마 활동에 버금갈 수 있는 품질불량 한자리 숫자의 목표실현과 함께 궁극적으로는 불량률 제로를 추구하는 무결점 운동으로서 그간 추진해 온 100PPM 품질혁신운동을 한국적 풍토에 적합하도록 개량 및 발전시킨 새로운 품질 혁신활동이라고 할 것이다. 본 연구에서는 그간의 100PPM 품질혁신활동 성과를 되돌아보고 Single-PPM 품질혁신의 추진절차에 대한 고찰을 통해 주요 특징을 찾아보고 국내 중소기업들의 실정에 적합한 품질문제 해결방 안으로서 자리할 수 있는 방안에 대해 검토하고자 한다.

Objectives : The purpose of this study was to examine the impact of the self-efficacy of dental hygienists on their stress-coping method. Methods : The subjects in this study were the dental hygienists in dental institutions that were selected by convenience sampling from Jeonju, Iksan, Gimjei and Gunsan in North Jeolla Province. A survey was conducted by using structured questionnaires. Results : A regression analysis was carried out to see whether self-efficacy would affect stress-coping method, and it's found that those whose overall self-efficacy was better made more use of an overall stress-coping method(p>0.001). General and social self-efficacy exerted a significant influence on a problem-oriented stress-coping method(p>0.001, p>0.01), and general and social self-efficacy had an impact on a stress-coping method of social support pursuit(p>0.01, p>0.01). In addition, general and social self-efficacy exercised an influence on a stress-coping method of wishful thinking(p>0.01, p>0.05). Conclusions : The self-efficacy of the dental hygienists affected their own stress-coping method, and the finding of the study suggests that a lot of efforts should be made from diverse angles to boost the self-efficacy of dental hygienists.

Researches based on the pattern of planned behavior holds that the three variables of entrepreneurial attitudes, subjective norms, and perceived behavior control influence each other and influence entrepreneurial intentions respectively. However, there are also different, even conflicting research conclusions that continue to emerge. Researches based on the pattern of alertness, believe that profit opportunities and individuals' pursuit to truth are the driving forces. Many scholars have demonstrated the impact of individual entrepreneurial alertness on entrepreneurial intentions. However, as an exogenous causal agent, profit opportunities have a logical problem: if there are no other assumptions, the mere existence of opportunities does not adequately explain entrepreneurial alertness. To address this gap, this study considered samples from mainland China, where entrepreneurial activities are very active currently, to test the role that entrepreneurial alertness is assumed to play in the planned behavior model. The results show that the three dimensions of alertness, individually partly intermediate the influence of entrepreneurial attitude on entrepreneurial intention, the influence of subjective norms on entrepreneurial intention, and that of perceived behavior control on entrepreneurial intention. This article studied the production of entrepreneurial intention by integrating the two patterns of planned behavior and alertness through empirical analysis, and opened up a new field for subsequent research on entrepreneurial intention.

Various forms of procurement are open to companies when constructing new owner-occupied properties. The selection of a form of procurement is an important decision-making problem for companies and their Corporate Real Estate Management (CREM) departments. With this in mind, a decision support tool has been developed to optimise the outcome and success of company's proposed real estate development projects and is presented in this paper. This model can also be used for current real estate portfolios to optimise returns in the long term. In pursuit of this objective and in order to provide an academic basis for this study, decision-relevant goals and parameters were initially identified from the referenced literature used in our research. These were subsequently evaluated in a case study of a corporate development project and identified as specific decision criteria from the perspective of the CREM. The investigation identified 15 criteria that are relevant to the corporate decision-making process in procuring and/or developing property. A model for supporting and resolving decision-making problems of this type was derived from decision theory. In this paper, a decision-making tool is presented that takes into account all the decision criteria from the CREM point of view for the first time. This model should therefore serve as an aid in implementing the decision-making process for the development of real estate projects in a more structured and transparent manner.

The purpose of this study is to accumulate basic data to establish planning direction and planning factors for the environment-friendly apartment complex. For this purpose, the survey has been conducted to residents living in an apartment housing and graduate students, architects and research experts in the field. The major findings of this study are as follows; 1) The basic concept of planning factors for environment-friendly apartment complex are energy saving, resources saving, minimizing environment pollution, natural harmony, regional identity and pursuit of residents' health & amenity. 2) For the planning factors of environment-friendly apartment complex, the residents had a great regard for aspect of Low-Impact (energy saving, resources saving, minimizing environment pollution). The experts, on the other hand, had a great regard for aspect of High-contact (natural harmony, regional identity). 3) It was increase of prime cost that the residents and experts regarded as the most important problem of planning and purchasing of environment-friendly apartment. It thus appears that the promotion of environmental consciousness of residents taking in the portion of increased cost is crucial parts and also that the role of the connected aspects such as administration, construction companies and residents must be redefined in order to manage problems caused in process of the development of it.

Purpose: This study was to identify and to search the related disposition of the pattern of anxiety and coping in mothers of children with nephrotic syndrome through the use of Q-methodology. Method: 34 Q-samples were finally selected in the concept of anxiety and coping. A P-sample of 35 was selected the mothers of children with nephortic syndrome. The result of the Q-sorting was coded and analyzed using QUANL PC program. Result: There were 3 types of special opinion. The first type is called ' Pursuit of hope type.' Members of this type were cope with the anxiety by spiritual behavior like a pray, positive thinking. The second type is called 'Worry about reality type.' Members of this type were to be filled with apprehension like an indigestion, insomnia. The third type is called ' Solving problem type.' Members of this type were cope with the humanity effort by conversation. Conclusion: The mothers of children with nephrotic syndrome were used various coping patterns to cope with the anxiety conditions that their child were result from admission to hospital and treatment of the disease. Therefore, nursing assessment and nursing intervention skills have to develop in consideration of the subjectivity of coping about anxiety in each individual.

Purpose: The purpose of this descriptive study was to explain the relationship between ways of coping and health-related hardiness in university students at G city. Method: The participants were a convenience sample of 250 students. The data were collected by a questionnaire given to the students between June 1 to June 10, 2006. Descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and stepwise multiple regression were used to analyze the data. Results: The most frequently used method of coping was pursuit of social support. The mean score for level of health-related hardiness was $3.34{\pm}0.55$. There were significant differences in ways of coping according to satisfaction with college life (F=4.036, p=.008). There were significant differences in health-related hardiness according to smoking or not (F=6.237, p=.002). There were positive correlation between problem focused coping and hardiness (r=.357, p=.000), between social support and hardiness (r=.345, p=.000), between hope seeking thought and hardiness (r=.247, p=.000). In regression analysis, ways of coping was significantly influenced by hardiness(16.6%). Conclusion: The results suggest that programs for strengthening hardiness can be considered as significant nursing interventions for helping university students cope with stress.

In this paper, it is intended to introduce a method to solve multi-objective optimization problems and to evaluate its performance. In order to verify the performance of this method it is applied for a vertical roller mill for Portland cement. A design process is defined with the compromise decision support problem concept and a design process consists of two steps: the design of experiments and mathematical programming. In this process, a designer decides an object that the objective function is going to pursuit and a non-linear optimization is performed composing objective constraints with practical constraints. In this method, response surfaces are used to model objectives (stress, deflection and weight) and the optimization is performed for each of the objectives while handling the remaining ones as constraints. The response surfaces are constructed using orthogonal polynomials, and orthogonal array as design of experiment, with analysis of variance for variable selection. In addition, it establishes the relative influence of the design variables in the objectives variability. The constrained optimization problems are solved using sequential quadratic programming. From the results, it is found that the method in this paper is a very effective and powerful for the multi-objective optimization of various practical design problems. It provides, moreover, a reference of design to judge the amount of excess or shortage from the final object.

Recent trend in pursuit of high performance and effectiveness for automotive cooling system has changed the application of material for impeller of automotive water pump from metal to high ability engineering resin, which can achieve optimization of design of impeller geometry and realize lightweight high efficiency water pump. Closed type water pump improves hydraulic loss of fluid through the clearance between volute casing and impeller compared with that of the existing open type water pump(Although closed type is heavier than open type for the same size and same material, adoption of plastics can solve the problem.). In the present study, the characteristics of hydraulic performance of closed type water pump were investigated with respect to the angle between shroud and hub of impeller and the shape of discharge port of volute casing. Performance tests were carried out for 4 cases, that is, for 2 impellers and 2 casings. The modification of shape of only discharge port can enhance the hydraulic performance by 10 percent and the pump efficiency by 4-6 percent.
