The purpose of this study is to overview domestic and foreign trends in the study of the landscape evaluation through new framework of landscape evaluation studies. 108 studies on the landscape evaluation are summarized and categorized into theoretical studies, verification of theories, development of evaluation methods and applications in physical planning. Major theories in the landscape evaluation came from the psycho-physics, the evolutionary theory ann the cultural-learning theory, and were verified and applied into physical planning. Early experimental researches on landscape evaluation, based on psycho-physics, were focused on relatively simple responses to landscapes. But many studies have been gradually related to the evolutionary theory and the cultural learning theory, emphasizing biological and cultural effects on landscape evaluation. Especially, Appleton's Prospect-Refuge theory' and Kaplans' 'Information Processing model' have very strong influence in landscape evaluation. Relatively there have been many application researches in Korea, which tells there have been strong needs to solve pending practical problems caused by the rapid economic and social growth for several decades. Almost of applications in physical planning are focused on physical features of landscapes, but for more comprehensive landscape evaluation, many other factors such as cognitive and sociocultural variables should be integrated into the whole evaluation system. As a result of reviewing of landscape evaluation studies, I found the overall domestic and foreign trends and the necessity of more research on the applications in physical planning. Because this study mainly focused on academic researches, for more appropriate landscape evaluation and management there should be more practical researches including various approaches.

The paper investigates the influence of government-led projects on investors' decision-making reference points, using Prospect Theory and Human Capital Theory. It empirically explores whether government initiatives shift investors' reference points, offering insights for private investments in government-backed ventures. The study, spanning from May 2017 to May 2022, compares 51 companies involved in Korea's 'New Deal' policy to 49 non-participating companies. It considers founders' human capital elements such as past startup experience, technical and managerial industry experience, education level, and graduate school reputation. The analysis reveals that only the reputation of the founder's graduate school has a significant negative effect, implying a conservative approach by investors towards government-led projects. This highlights the need for investors to consider the founder's social capital and the impact of government support on venture growth and public offering pace.

When and why do states cooperate in international basins? In recent years, there have been increasing attempts to apply international relations theories such as realism and neo-liberal institutionalism in understanding prospect of cooperation among sovereign states over shared rivers. Realists of hydropolitics argue that fate of cooperation resides in hands of hegemons and distribution of aggregate power among riparian states. Such pessimistic contention has been challenged by neo-liberal institutionalists, especially through regime theory. However, regime theory barely explains why and how cooperation emerges in the first place prior to regime formation. Therefore, the research suggests the game theory from neo-liberal institutionalism as an alternative theoretic approach. The accountability of Oye (1986)'s theoretical framework is illustrated through the case of cooperation in the Rhine River Basin.

Purpose: Planning space of the house is important as a universal place to relieve stress of contemporary people. Void space is easy to perform mental and cultural programs in aspect of affording the healing behavior. The "Interface" accommodates healing behaviors through mutual interchange between void space and solid space as the edge of the solid space around void space. This study presents a efficient theory of healing space through combining space theory with the Kitwood's theory of psychiatry used for the art therapy. Methods: Spatial elements based on Kitwood's theory converges towards 2 behavioral elements; Meditation(-), Sense of Community(+). Balancing with reciprocal complement between behaviors of passive and stable "Meditation(-)" and active and released "Sense of Community(+)" was analysed. Results: "Faciliation" can be used in combination with "Flow(+)" as active factor. "Validation" is combined with "Prospect(+,-)", and divides into 2 factor ; "Recognition-Refreshment(-)", "Reaction-Social Exchange(+)". "Holding" is combined with "Refuge(-)" as passive factor. Implications: This study established concept of spatial healing elements in connection with theory of Psychiatry about Alzheimer that is extreme situation of stress. This study is expected to enhance the validity and efficiency in analysis of healing space.

This study is the analysis of characteristics of hospital space for the holistic healing environment of children on the basis of the healing theory on emotion of Max L$\ddot{u}$scher and the healing theory on senses of Rudolf Steiner of the overseas children's hospitals. According to the theory of Rudolf Steiner, children make comprehensive advancement of physical, spirit and soul through the interaction of 12 senses. In addition, Max Luscher asserts that the psychological health can be maintained when the 4 emotional status in content, confidence, self-esteem and liberty make the balance. The 4 elements of Luscher have correspond with spatial expression elements for refuge, flow, prospect and void, and this is analyzed in conjunction with the eight kinds of behavior affordance of ying and yang (-, +) that helps our the advancement of 12 senses of Steiner. WORK & STUDY(+), REST(-), MOBILITY(+), VISUAL SEQUENCE(-), SOCIAL EXCHANGE(+), REFRESHMENT(-), COMMUNITY(+) and MEDITATION (-) would be the 8 kinds of behavioral affordances to make the healing environment as presented in this study and the case analysis for children's hospitals have been undertaken.

Dynamic behavior of the harmonic detection part of an active power filter (APF) has an essential role in filter compensation performances during transient conditions. Instantaneous power (p-q) theory is extensively used to design harmonic detectors for active filters. Large overshoot of p-q theory method deteriorates filter response at a large and rapid load change. In this study the harmonic estimation of an APF during transient conditions for balanced three-phase nonlinear loads is conducted. A novel fuzzy instantaneous power (FIP) theory is proposed to improve conventional p-q theory dynamic performances during transient conditions to adapt automatically to any random and rapid nonlinear load change. Adding fuzzy rules in p-q theory improves the decomposition of the alternating current components of active and reactive power signals and develops correct reference during rapid and random current variation. Modifying p-q theory internal high-pass filter performance using fuzzy rules without any drawback is a prospect. In the simulated system using MATLAB/SIMULINK, the shunt active filter is connected to a rapidly time-varying nonlinear load. The harmonic detection parts of the shunt active filter are developed for FIP theory-based and p-q theory-based algorithms. The harmonic detector hardware is also developed using the TMS320F28335 digital signal processor and connected to a laboratory nonlinear load. The software is developed for FIP theory-based and p-q theory-based algorithms. The simulation and experimental tests results verify the ability of the new technique in harmonic detection of rapid changing nonlinear loads.

Philosophers Of aeBthetics have tended to limit their Suhject to include only objects Of art. In contrast to art objects, landscapes include elements of both art and nature, and the aesthetic experiences of landscape are ordinarty ones. Thus, the theoretical alternatives, that cannot be like the traditional aesthetic dogma of art, must be explored. Jay Appleton's theory is the firsts attempt to develop a comprehensive theory of landscape aesthetics. He concentrates on the question 'what do we like about landscape and why do we like it ' He takes the assumption that the aesthetic experience of landscape is pleasurable or satisfying, and suggests the biologically oriented theory, called 'prospect-refuge theory.'Although his theory is stimulating and highly speculative, it depends on the 'aesthetic attitude' theory of Kantian thought. His theory can be criticized for its biologically deterministic nature and its reductionism To respond to Appleton's shortcomings, that is, to resolve the conflict between biological and cultural explanations of aesthetic experience of landscape, Steven Bourassa tries to combine biological, cultural, and personal modes in a comprehensive paradigm for research in landscape aesthetics. This tripartite paradigm seems to promise to be meaningful if helping to pose important questions as well as in. avoiding conceptual errors about aesthetic domain of landscape. However, Bourassa's theory fails to integrate such three separate kinds of moder In the final analysis both Appleton and Bourassa present same succeases in expanding the scope of aesthetics to embrace landscape. Most important for a theory in landscape aesthetics must be its ability to enlarge our awareness of the aesthetic domain and its sound logic and evidence to criticize our problematic beliefs about he aesthetic idea of landscape.
