The purpose of this research is to arouse attention to the importance of eliminating the 'Shadow Encroaching Phenomena on the Essence' in advertising expression by interdisciplinarily applying ethicality. This research shows that when advertising expression is planned and executed without enough consideration of ethicality, short-term effectiveness to reach goals can be increased, but it is easy to induce an unintended 'Shadows' Boomerang Phenomena'. This research also proposes that such processes arouse consumers' ethical defense mechanisms, possibly causing the 'Shadow Encroaching Phenomena' in the end. In conclusion, this research proposes the following. First, the pursuit of commercial profit in a capitalistic society must be done under the premise of securing a consensus of ethicality in a common society. Second, under the premise of an integrated process of education, sharing, execution, and confirmation of ethicality, companies can achieve both the micro-practical goal of profit pursuit and the macro-environmental goal of ecological sympathy.

This study investigated student's prior conceptions and evidence evaluation about Light and shadow. One hundred twenty six students were given Explanation-after-choice type Questions to investigate student' prior conceptions and Choicd type Question to identify student's idea about scientific method and characteristics od observation. Forty-four of the 126 students were interviewed to explore student's evidence evaluation. Eighty students (63.5%) thought that the shape of material affected the shape of shadow but the shape of light source did not Only 58.8 precents of all responses were evidence-based responses. Characteristics of evidence affected student's evidence evaluation : student made evidence-based responsed to the accord evidence more frequently than discord evidence. Among evidence-based response to the discord evidence. 35.5% of responses were the case that student felt cognitive conflict or explored other variables by recognizing discord between his/her own ideas and evidence or distort the evidence. Student's idea about characteristics of observation did not affect the evidence evaluation, but student's idea about scientific method affected the evidence evaluation.

We present a simple method of determining the absolute order of moire fringes formed by the moire shadow topography with a criss-crossed grating. Two experimental methods in this topography are proposed and demonstrated; one is to change the ratio of x and y pitches in a criss-crossed grating after fixing the position of a light source and a camera, and the other is to change the position of a light source and a camera after fixing the ratio of x and y pitches in a criss-crossed grating.

This study explores the following research question to address issues linked to emotions, identity, and institutions: how has the cult (institution) of the three Kims affected North Koreans' strong sense of nationalism (emotion), which is based on their Juche ideology (identity)? This paper investigates four fundamental elements of historical institutionalism: time boundedness, path dependency, institutional changes, and the shadow of the past. First, time boundedness illustrates how culture and education have been used to build trust and loyalty in the general public to construct individual and family cults. Second, path dependence reveals how the Songbun system has resulted in strong nationalism throughout Rodongdang's institutionalization. Third, institutional changes highlight the significance of age divides, as different age groups do not always support the three Kims' cult. Finally, the shadow of the past helps us understand the primary processes for generating mass ardent nationalism in the form of powerful impulses for self-sacrifice.

In addition to improving economic growth and development of advanced production technology brings many benefits to our society, but if the growth of this still has the shadow of accidents exists. In particular, the construction site has seen a significantly higher accident rate figures despite efforts on disaster prevention. Among the various methods of reducing the need for disaster safety education industry it has become very stressed its importance through many studies. When a disaster causes significant share of the construction industry due to the lack of educational causes, including technical causes, managerial causes, classification and educational causes of this ateumyeo safety awareness and knowledge account for large proportion. In the health and safety education, centered on the subjects of education supervisors will be able to reduce the real and effective industrial disaster education should be run.

This study examines the process of Chou Sun-Ae's spiritual formation in the light of Carl Jung's conception of individuation. Spirituality is defined in different ways by different scholars, but most consider self-transcendence as a necessary element. This self-transcendence can occur in the relationship with self, with others, and with the transcendent. In the relationship with the self, it appears as self-objectification; with others, it is as moving toward others; and in the relationship with the transcendent, it moves toward the transcendent. Spirituality is closely related to individual identity, in that it surrounds and integrates life. Spiritual formation is thus closely related to Jung's concept of individuation, as this involves the separation of persona and ego, and shadow recognition which are closely related to the level of self-objectification. In addition, the withdrawal of shadow projection that occurs in individuation is closely related to moving toward others, in that it recognizes the shadow instead of blaming others, allowing one to look at others without prejudice. The fact that Jesus Christ is the symbol of the Self, the driving force of the individuation process, tells us that spirituality leading to a relationship with the transcendent God and Jung's theory are closely related to each other. Thus, if we examine the process of spiritual formation through the Jung's individuation process, we can better understand the psychodynamic dimension of spirituality. This article investigates the process of Chou Sun-Ae's spiritual formation through Jung's individuation process. Throughout her 98 years, Chou Sun-Ae experienced national pain and hardships, as well as personal adversity and difficulties; but through all of these hardships, conflicts, and difficult moments, she accomplished individualization. Therefore, by examining the spiritual formation through individuation in Chou Sun-Ae, I consider the direction of Christian spiritual education. In this study, three main characteristics of Chou Sun-Ae's spiritual formation can be identified. First, through a life of repentance, the identification between persona and ego can be weakened. Second, the ego develops, and individualization is achieved, through a new calling. Third, in shadow integration, the spiritual development comes to recognize Jesus Christ on the cross and achieve the process of sanctification. Investigating the direction of Christian spiritual education through Chou Sun-Ae's spiritual formation indicates that Christian spiritual education should harmonize vertical and horizontal relations and should develop an experience of the transcendent God in everyday life. By this means, the believer can achieve Self-realization and be a true Christian who practices love for God and love for neighbors.

Recently, the use of real-world image data has been increasing to express realistic virtual environments in various application fields such as education, manufacturing, and construction. In particular, with increasing interest in digital twins like smart cities, realistic 3D urban models are being built using real-world images, such as aerial images. However, the captured aerial image includes shadows from the sun, and the 3D city model including the shadows has a problem of distorting and expressing information to the user. Many studies have been conducted to remove the shadow, but it is recognized as a challenging problem that is still difficult to solve. In this paper, we construct a virtual environment dataset including the height map of buildings using 3D spatial information provided by VWorld, and We propose a new shadow detection method using height map and deep learning. According to the experimental results, We can observed that the shadow detection error rate is reduced when using the height map.

The empirical law that transverse dunes migrate inversely with their heights leads logically to the prediction that multiple dune ridges will converse to a single huge dune by merging. This contradicts the existence of the steady state dune fields on the Earth. The recent studies have emphasized dune collisions as a key mechanism to the stability of dunefield. The roles of wind shadow aspect ratio, however, have yet to be fully explored. This research aims to investigate the potential roles of wind shadow aspect ratio in the dynamical behaviors of transverse dune field. The simplified model is established for this, based upon allometric properties of transverse dunes, wind speedup on the stoss slope and sand trapping efficiency. The derived governing equations can be transformed to the zoning criteria and vector field for dune evolution. The dynamics analysis indicates that wind shadow aspect ratios do not produce convergent areas on the behavior space; rather, they just act as one of the factors that affect the trajectories of dune evolution. Though the model cannot represent the stability of dune field, but seem to produce a reasonable exponent for dune spacing-height relations.
