Studies and applications related to unidirectional flow are gaining attention from researchers across disciplines in the recent years. Flow can be viewed as a concept, where the material, fluid, people, air, and electricity are moving from one node to another over a transportation network, water network, or through electricity distribution systems. Unlike other networks such as computer networks, most of the flow networks are visible and have strong material existence and are responsible for the flow of materials with definite shape and volume. The flow of electricity is also unidirectional, and also share similar features as of flow of materials such as liquids and air. Generally, in a flow network, every node in the network participates and contributes to the efficiency of the network. In this survey paper, we would like to evaluate and analyze the depth and application of the acyclic nature of unidirectional flow in several domains such as industry, biology, medicine, and electricity. This survey also provides, how the unidirectional flow and flow networks play an important role in multiple disciplines. The study includes all the major developments in the past years describing the key attributes of unidirectional flow networks, including their applications, scope, and routing methods.

Purpose: The purpose of this study was to collect basic data on social support and acculturative stress in migrant workers. Methods: Between August, 2007 and January, 2008 171 immigrant workers completed data collection using a questionnaire. Workers were recruited from 2 churches, one in Seoul and the other in Gyeonggi Province. Mean and standard deviation, t-test, ANOVA, Pearson correlation coefficients and Stepwise multiple regression were used to analyze the data. Results: The average score for social support was 3.73 (${\pm}0.65$) and for acculturative stress, 2.52 (${\pm}0.65$). There were significant differences acculturative stress according to gender (t=2.152, p=.033), kind of job (t=2.597, p=.040), and have community or not (t=2.899, p=.005). There was a significant negative correlation between social support and acculturative stress (r=-.270, p=.001). Factors influencing acculturative stress were existence of participants having a community of people from their home country or not ($R^2=.151$, p=.002). Conclusion: More studies are needed to identify the variables that influence acculturative stress in immigrant workers.

The color of object is a main role that people recognize outdoor entity with its shape. We can perceive the object due to the existence of light such as direct sunlight. Light is classified by wavelength into radio, microwave, infrared, the visible region we perceive as light, ultraviolet, X-rays and gamma rays. White light is all of the colors of light combined within the visible light spectrum. When white light is separated through a prism, we see the visible light spectrum. The various wavelengths of visible light are separated into colors. In this paper, we construct white light as the seven colors of rainbow and suggest the method of N-way color dispersion photon mapping to simulate the natural dispersion phenomenon.

Do managers in health center perceive red tape in their organizations\ulcorner Most people would think so, but researchers have often found that health center organizations do not necessarily have higher levels of rule intensity than private hospitals. It there are higher levels in health center organizations, what explains their existence\ulcorner In this article, I discuss the results of a survey of health center managers that explored their perceptions of red tape in their organizations. Red Tape can be defined as rule and procedures that occured a excessive regulation. The survey included two dimensions and two hypotheses of red tape in health center managers. The hypotheses included health center and size that claims cause managers to create red tape. 119 managers who working in health center and private hospitals in Chonbuk area, participated in this study which was conducted by direct interview. The results show some support for two hypothses. The results showed some differences between health center and private hospital managers' perceptions about certain aspects of red tape. I also found differences between large size and small size managers' perceptions. The study call for more systematic analysis of red tape, including the use of methods, in support of current reform efforts aimed at reducing red tape.

Fashion leadership is divided into visual influence, linguistic influence, and dual leadership. We refer to people exercising such influential power as fashion innovators, fashion opinion leaders, and fashion double leaders, respectively. Scholars and marketers have raised continuous questions on this issue: who are these fashion leaders and what characteristics do they have? In this study, social network analysis is applied to grasp the existence of three types of fashion leaders in college clubs, examine their positions in fashion process networks and investigate their individual and social characteristics. For this study, three college clubs were recruited through convenience sampling and surveyed online. Peer nomination questions for structuring fashion process networks and self-evaluation questions for measuring personal characteristics are included. Two fashion networks, an opinion leadership network and an innovativeness network, embrace four to six leaders and illustrate similar structure patterns in the three groups, which indicates that dual leaders enjoyed the lion's share in college clubs. The number of fashion innovators tends to be fewer compared to that of fashion opinion leaders, and we infer that peer relationship appears to intervene with fashion opinion leadership. Other personal characteristics supporting results from previous studies are also confirmed in this study.

Even though Chilean writer Roberto $Bola{\tilde{n}}o^{\prime}s$ novel Amulet was inspired by a historical account, it significantly rewrites the story as well as redefines the people who witnessed the history. This novel focuses on the Uruguayan poet Auxilio Lacouture, the self-anointed "mother of Mexican Poetry". She is trapped in a bathroom at the UNAM in Mexico City for thirteen days while the army storms the campus for the repression of the student movement, which was decreed by the sinister Díaz Ordaz and culminated in the holocaust of Tlatelolco. In the space isolated from the outside world, Auxilio attempts to reconstruct the past and to describe the future through an illogical exercise of times. In the meantime, her temporal recollections finally approach the definition of a generation whose historical experience is crucially marked by the key year of 1968, when the novel is set. The only one who remained on the campus, she defends the university's autonomy only by reading and writing poetry. The novel ends in a scene densely imbued with allegorical imagination, by which the author endeavors to justify her generation, more concretely, "the peoples without history", as defined by bohemian poets. The protagonist represents, in some sense, an allegory of the innocence and truth of the history. Her existence per se manifestly demonstrates the power of literature because the literature within this novel in short becomes the most resilient amulet resisting the political violence in an era of increasing madness.

The purpose of this study is to show typology of virtual world and to look out how virtual world develops especially in Korea. As paradigm changes, the scientific virtual reality and world wide web are absorbed into 3-D virtual world in Metaverse. The metaverse is the convergence of virtually enhanced physical reality and physically persistent virtual space. There are two categories of virtual world, the Ludic Virtual World which is oriented from games like MMORPGs and the Social Virtual World which is oriented from network communication system. Compared to North America and Europe, the Ludic Virtual World and game society grow and develop quickly in Korea. It's because Korean users prefer the online environment where millions of people live out a collective fantasy existence.
