  • A creative innovation and an innovative problem-solving of industrial companies can be achieved by overcoming the challenges of technical and physical contradictions. The approaches to address conflicting and paradoxical problems, such as technical and physical contradictions have a crucial role in advancing the quality assessment for manufacturer and service provider. The term, technical contradiction, depicts the state that improvement of one ends of IFR (Ideal Final Result) leads to unfavorable condition of the other ends, and results in conflicting problem. Another type of contradictions that's discussed in this study is a physical contradiction which is due to two mutually opposing states of the means of ends, and gives paradoxical situation. By integrating the means-ends chain perspectives, the physical contradiction that is a specifically root-causes, "means", can be initially addressed to resolve the downstream problem of technical contradiction which represents a general and abstract goals, "ends". This research suggests IFR resolution processes to handle both physical contradiction of means and technical contradiction of ends by employing causal relationship with IFR, effects and causes. In summary, the study represents three major processes that resolve such contradictions are demonstrated as follows: 1) Derivation of causal and hierarchical relationship among IFR, ends and means by considering CAED (Cause-And-Effect Diagram) and LT (Logic Tree). 2) Identification of causal relationship between physical contradiction and technical contradiction by using TPCT (TRIZ Physical Contradiction Tree) and TCD (Technical Contradiction Diagram). 3) Application of integrated TRIZ principles by classifying 40 inventive principles into 4 general conditions of the separation principle of mutually opposite states in space, in time, based on conditions, and between the parts and the whole. In order to validate the proof of proposed IFR resolution processes, the analysis of the TRIZ case studies from National Quality Circle Contest in the years, 2011 to 2014 have been proposed. The suggested guidelines that are built based on TRIZ principles can uniquely enhance the process of quality innovation and assessment for quality practitioners.

  • Purpose: This study was conducted to identify relationships among nursing activities, the use of body mechanics, and job stress in nurses with low back pain. Methods: Participants were 225 nurses with low back pain working at an university hospital. The data were collected with self-reported questionnaires at March, 2012 and analyzed by descriptive statistics, t test, ANOVA, Scheff$\acute{e}$e test and multiple regression analyses. Results: There was significantly a higher degree of pain in subjects who working at special units including intensive care units and emergency room than at general wards. Low back pain was negatively correlated with the use of body mechanical principles while it was positively associated with the degree of job stress. According to results of multiple regression analyses, low back pain was significantly associated with the use of body mechanics and job stress in nurses working at general ward and special units including intensive care units and emergency room. Conclusion: The use of the principles of body mechanics and reducing job stress are important to prevent low back pain in nurses. It is necessary to develop and apply stress management and education program about the use of the principles of body mechanics.

  • The purpose of this study is to provide general principles to be used in designing university websites from the perspective of information architecture. Quantitative and qualitative evaluation criteria of web sites were developed based on information architecture principles. The students taking IA class were directly involved in constructing the evaluation criteria and they can be classified into four categories: 1) information organization; 2) navigation system; 3) labeling system; and searching system. These criteria were employed in evaluating twenty randomly selected university websites in Korea. General principles to be used in designing university websites were developed based on the findings of the study. They are composed of four major components in designing: 1) systematic information organization; 2) flexible navigation system; 3) consistent labeling system; and 4) efficient searching system.

  • In the absence of any guidance under statutory law, such as the Rules for Construction of Policy, MIA 1906, judges should follow the general principles of interpretation that apply to all contracts. In simple terms, Contra Proferentem Rule means that if the contents of the terms and conditions are ambiguous, they are interpreted against the writer of the terms and conditions. In the Anglo-American Contract Law, the 'default rule' is an important judicial tool that can supplement defects in contract norms and reinforce the principle of private autonomy through gap-filling techniques related to the interpretation of contracts. In Korea, it is sometimes mentioned in case of precedent, and it has been established as a clear rule. This study analyzes the interpretation of terms and conditions is not in the form that the interpretation of other general contracts and other interpretation principles are valid, but contracts based on terms and conditions are also contracts, and as a general rule, the interpretation of terms and conditions is explained like the general contract interpretation.

  • With the increasing concern over the air quality degradation, there are growing demands to accurately and precisely measure air quality. In this article, the general principles and approaches were described to help aid proper evaluation of air quality. In order to introduce the basic approaches for conducting field/laboratory experiments and for interpreting experimental data sets, we explained all the common methodologies involved and provided some insights into the desirable protocols for air quality measurements.

  • Liquid crystal (LC) devices can be operated as amplitude modulators and phase modulators. They usually require two polarizers; therefore the optical efficiency is limited. We introduce two general principles of polarization-free liquid crystal devices and also show several LC devices by applying the principles.

  • It has been criticized that the Venice Charter of 1964 characterizes so much of Western value of architecture and its conservation, despite its significant contribution towards an international conservation approach. Since the 1970s some countries have drawn up their own conservation guidelines to supplement the limitations of the Venice Charter. When we review critically those documents, we find a change in the Western dogma of heritage. Although the Burra Charter of 1979(last version in 1999) and the China Principles of 2002 accept the general philosophy and concepts of the Venice Charter but make responses to special local needs. The Burra Charter has redressed a current Western bias which has permeated global conservation practices, responding to the Australian context. The China Principles also meet special national needs but in accordance with recent international practices. For this reason, the Burra Charter and the China Principles are regarded as well established in national conservation practices but also as representing each country's contribution to contemporary international conservation practices.
