Nature preservatio has been a main stream trend as the purpose and meaning of world's national park management since the definition of a national park was first adopted at the IUCN meeting in New Delhi in 1969. However, Korea's national parks have been managed in a direction opposed to that of the world trend. The internationally accepted meaning defines a national park is the most important system for nature conservation, where an ecosystem must be preserved in as much of a natural state as possible. It also defines a national park is a place where only the minimum amount of human intervention is allowed. The role of tourism, which was initially expected to play a significant role in national parks, has been reduced to the extent where tourism in national parks is allowed only to the point where conflicts arising from local socio-economic interests tied up to the tourism can be dealt with. From this perspective, Korea's national parks are being challenged to establish new relationship between mean and nature and to develop management based on ethical grounds for future generations.

In Korea, about 60 percent of railroad accidents are associated with highway-rail grade crossings numbering 1,657 nationwide, which the railroad system operates. To reduce the number of accidents, the authority formulated methods to improve or eliminate grade crossings. However, the improvement programs have made progress in slow time due to the institute inertia and the lack of funds from the municipal government, which shares the cost of improvement of grade crossings. Thus, this study analyses the institute system of the grade crossings, proposes modifications, and suggests financing methods to improve the grade crossings and to lower the number of accidents. Presently, the grade crossings safety perspective is directed towards road conditions and so a new perspective, which includes safety from the train perspective and to finance in review of railway system and to allocate the cost between the central government and the municipal governments. is discussed.

This study is purposed to find the transition of the perspective connected with visual modality. The perspective based on Greek optics and euclidean geometry and rediscovered in Renaissance represents the object according to the particular moment and the point of view, is a principal fact which affect architecture, the form of a city and the spatial organization and symbolizes an ideal of the times. It embodied perception which treats the space rationally on the basis of realism and became visual modality based on the separation of the seeing subject and the world of the object. The point of view became one with the vanishing point which made up the shape and after Renaissance for four hundred years a straight line, a right angle and a circle got to be favorite geometrical choices in architecture. A fixed point of view of the subject is getting to change and break up fundamentally by the new visual technologies of the modem times.

This study pursues the problems of plan photogrammetry which is widely used in somatotyping at present, and find out a method which can improve accuracy of measurement on the basis of principles and mechanisms of photography-the basic foundation of the photographic analysis methods. As a result, this study proposes a new method which is based on the reference point method and perspective coordinate system. And the test measurement was operated to compare the measurement accuracy of the proposed method and the method based on reference grid screen method and perpendicular coordinate system which is commonly used at present. The result of this test measurement showed that the proposed method has higher accuracy. Two reasons can be pointed out for the improvement of measuring accuracy. The first reason is that the proposed perspective coordinate system reduces the perspective distortion of photography. And second reason is that measuring points can be closely placed to the scale and coordinate reference plan of measurement by the proposed reference point method which make possible to place measuring object (or person) at the center of scale and coordinate reference plan by utilizing reference points of measurement in the three dimensional space not on screen.

It is argued that the strategy practice in the 21st digital organization is limited and constrained in that it is being laregy driven by a traditional positivistic strategic management thinking. This article, drawing upon the models and concepts developed in the field of general ecology, proposes a resilient ecological view of strategy, as an alternative strategy frame of reference for overcoming some of the pitfalls and shortcomings of the current digital strategy practice in the organization. The implications of this new ecological perspective on strategy practice are discussed in detail. The article concludes with discussions and directions for implanting the perspective in the organization.

Pythagorean theorem is a proposition on the relationship between the lengths of three sides of a right triangle. It is well known that Pythagorean theorem for Euclidean geometry deforms into an interesting form in non-Euclidean geometry. In this paper, we investigate a new perspective that replaces right triangles with 'proper triangles' so that Pythagorean theorem extends to non-Euclidean geometries without any modification. This is seen from the perspective that a rectangle is an equiangular quadrilateral, and a right triangle is a half of a rectangle. Surprisingly, a proper triangle (defined by Paolo Maraner), which is a half of an equiangular quadrilateral, satisfies Pythagorean theorem in many geometries, including hyperbolic geometry and spherical geometry.

The data is a key catalyst for the development of the fourth industry, and has been viewed as an essential element of the new industry, with technology convergence such as artificial intelligence, augmented/virtual reality, self-driving and 5 G. This will determine the price and value of the data as the user uses data in which the data is based on the context of the situation, rather than the data itself of the past supplier-centric data. This study began with, what factors will increase the value of data from a user perspective not a supplier perspective The study was limited to public data and users conducted research on users using data, such as analysis or development based on data. The study was designed to gauge the value of data that was not studied in the user's perspective, and was instrumental in raising the value of data in the jurisdiction of supplying and managing data.

To date, we have made inferences on the behavior and mind of humans and animals from the perspective of humans, or for the sake of familiarity, vertebrates. The book, "Other Minds; The Octopus, The Sea, and The Deep Origins of Consciousness" by Peter Godfrey-Smith makes us realize how erroneous preconceived notions could be, and presents a novel perspective on the results of evolution. Throughout this book, readers will learn about the characteristics of the nervous system, behavior, and habits of cephalopods, which include octopuses. Through this book, readers will gain a new perspective on the embodiment, minds, nervous systems, consciousness, and sociality of humans and animals. Furthermore, the book will provide the imaginary experience of swimming in "Octopolis" inside the ocean with the author.

Bad weather conditions such as haze lead to a significant lack of visibility in images, which can affect the functioning and reliability of image processing systems. Accordingly, various single-image dehazing (SID) methods have recently been proposed. Existing SID methods have introduced effective visibility improvement algorithms, but they do not reflect the image's perspective, and thus have limitations that distort the sky area and nearby objects. This study proposes a new SID method that reflects the sense of space by defining the correlation between image brightness and haze. The proposed method defines the haze intensity by calculating the airlight brightness deviation and sets the weight factor of the depth map by classifying images based on the defined haze intensity into images with a large sense of space, images with high intensity, and general images. Consequently, it emphasizes the contrast of nearby images where haze is present and naturally smooths the sky region to preserve the image's perspective.

The study analyzed the characteristics of the daily life and the living arrangements use of the elderly with literature review after the modernization period based on the daily life perspectives. The changes in the ideology, social system, and family system, which influenced the society and families, also affected the status of the elderly and their daily lives. Consequently, they had been facing conflicts, acceptance, and internal differentiations. The characteristics of the changes in the daily lives of the elderly in different periods were as follows. The contents were written from three different perspectives, phenomenological, symbolic interaction, and Marxist. During the modernization period, the family system and the hierarchy within a family had been reformed. However, the elderly were still considered as the symbolic leader and the respected figure of the family. From a phenomenological perspective, elderlies teach the next generations and influence the family's lives. On the other hand, from a perspective of symbolic interactions, spatial adjustment behaviors toward the largest room between the elderly and the next generation were detected. The actual authority was given to the next generation. However, the elderly were still treated as the symbolic authority. Yet, as the society became more industrialized, conflicts aroused about the support of the elderly. Those, who were neglected from the family, even spent their daily time at the elderly center or the community center. The daily lives from the Marxist perspectives suggested that modernization caused the young generations, who were well-educated and had financial powers, to have initiatives. The role of the elderly was reduced and they became negligible people, who spend meaningless daily lives. The interested the Third Ages is a new perspective on the elderly, who were neglected from the industrialized society. From a phenomenological perspective, the Third Ages are the generations that seek and demand for new housing.
