The disease concept of interstitial lung disease with idiopathic pulmonary fibrosis at its core has been relied on for many years depending on morphological classification. The separation of non-specific interstitial pneumonia with a relatively good prognosis from usual interstitial pneumonia is also based on the perception that morphology enables predict the prognosis. Beginning with dust-exposed lungs, initially, interstitial pneumonia is classified by anatomical pathology. Diagnostic imaging has dramatically improved the diagnostic technology for surviving patients through the introduction of high-resolution computed tomography scan. And now, with the introduction of therapeutics, the direction of diagnosis is turning. It can be broadly classified into to make known the importance of early diagnosis, and to understand the importance of predicting the speed of progression/deterioration of pathological conditions. For this reason, the insight of "early lesions" has been discussed. There are reports that the presence or absence of interstitial lung abnormalities affects the prognosis. Searching for a biomarker is another prognostic indicator search. However, as is the case with many chronic diseases, pathological conditions that progress linearly are extremely rare. Rather, it progresses while changing in response to environmental factors. In interstitial lung disease, deterioration of respiratory functions most closely reflect prognosis. Treatment is determined by combining dynamic indicators as faithful indicators of restrictive impairments. Reconsidering the history being classified under the disease concept, the need to reorganize treatment targets based on common pathological phenotype is under discussed. What is the disease concept? That aspect changes with the discussion of improving prognosis.

In this paper, we introduce a concept of the ${\epsilon}_0$-limits of vector and multiple valued sequences in $R^m$. Using this concept, we study about the concept of the ${\epsilon}_0$-dense subset and of the points of ${\epsilon}_0$-dense ace in the open subset of $R^m$. We also investigate the properties and the characteristics of the ${\epsilon}_0$-dense subsets and of the points of ${\epsilon}_0$-dense ace.

In this paper, 'relations of proportion are used in the introduction of function concept' in 7-first stage of 7th mathematics curriculum is focused. Under the assumption that above statement means dependence-centered view in the teaching of function, the contents of function In 7-first stage is interpreted. Some issues are critically contemplated, And, finally, statement of using relations of proportion in the introduction of function concept is interpreted as dependence-centered view in the teaching of function. Conclusions are as follows: (1) symbol y= f(x) is not inevitable. (2) Term 'codomain' must not be used. (3) Term 'range of x' and 'range of y' must be used. (4) Term 'independent variable' and 'dependent variable' must be used.

Purpose: This paper will focus on the reliability technological innovation following the emergence of industry 4.0 featured by convergence, connection and complexity. In the course of the process, the concept and application of 3R (Robustness, Redundancy, Resilience) are considered along with reliability in industry 4.0. Methods: Reliability paradigm-changes are presented to meet the purpose of keeping the desired function in Industry 4.0. And the introduction of resilience, a concept compromising reliability is to be suggested. Results: The necessity of the 3R (Robustness, Redundancy, Resilience) introduction is emphasized according to reliability paradigm-changes. Conclusion: Reliability, robustness, redundancy and resilience are not mutually exclusive. Ultimately, acquiring the resilience requires robustness, redundancy and fittable maintenance procedures.

The purpose of this study is to present the problem of the introduction and management and the method of activation of the team organization in college administrative systems through the theoretical study about the team systems and the actual proof study already introduced and operated in colleges and enterprises. The scopes of the subject of theoretical study are the concept of team systems, the type of systems, the strategy of introduction and management, the problem of management and the tactics of activation. The scopes of the theoretical study are the field of systematic structure and that of introduction and management. In order to activate the team organization of college administrative systems, we must study three points such as empowerment, construction of learning team and the method of personal management. For the sake of conducting the team organization efficiently, we must consider four fields. They are as follows: First, considering the continual efforts for reorganization is the most important precondition. Second, the device of supplement related with introduction of systems such as evaluation of merits, promotion and budget must be prepared as soon as possible. Third, in order to introduce the systems, the improvement of systems is needed. Fourth, it must be accompanied by redesigning the whole business process. Especially, in the introduction of team organization, it is important above all to introduce suitable constitution or situation of business. And making a constant effort and preparation for solving problems is essential to successful management of team organization.

The concept of social capital has recently been highlighted in most fields of social science because social capital is believed to be an alternative of market and government failures. However, social capital is of high ambiguity that hinders in conceptualizing and modeling that can differs from the premises, such as whether social capital lies in individual actors or collective substances, or whether social networks are functioning by rationality or emotion. This study therefore tries to examine the concept of social capital and suggest 6 types of it following by the anthropologic concept of 'reciprocity' as well as to provide fruitful discussions on the introduction of social capital variables to System Dynamics modeling of sustainable development. Conclusively, the introduction of social capital to the integration models of environment-economy-society should be based on strongly understanding the social networks, individual identities, and local particularities of the relevant localities in order to enhance the structural validity and applicability of sustainable development models in System Dynamics.
