When newsreel was organized in 1967, it was a small but strong revolution. New York newsreel became the third world newsreel in 1972. The third world newsreel clearly stated that the purpose of the organization should be the alternative provision of the Television news. They also notified the revolution of the production system and the distribution system. Christine Choy who actively worked at the Third world newsreel succeeded the spirit of the organization through her works. Through the third world newsreel and Christine Choy who was the representative of the organization, this article is dealing with the mode of production and the style and the aesthetics of the Newsreel. Their activities were originally political and always controversial. They agonized who should be the film maker, how should be the distribution system. Through the strong arguments, the group had acquired not only collective identity but also collective production. Those collaborations had become the foundation of their works. Christine Choy has been a key figure of the Third world newsreel and her films has focused on the racial problem and gender problem. Her works have always been political and historical.

Today, in order to more effectively cope with the emergence of various diseases and the rapidly-changing medical environment, several medical departments are conducting treatment collaborations within the university hospital. This collaborative care is very important and is already common in the medical field. Nevertheless, there is no research on this, especially how the departments are collaborating. Therefore, the purpose of this study is to investigate how the characteristics of the treatment collaboration networks vary by year and season by exploring the relationship between the medical departments within the university hospital. This study analyzed the collaboration networks of 29 medical departments of 'A' university in Korea by dividing the collaborative care by year and season. Directed networks were constructed in response to departments requesting and departments requested for collaborative care. Betweenness centrality, eigenvector centrality, closeness centrality analysis, ego network analysis, and faction analysis were also conducted. This study performed the first treatment collaboration network analysis among medical departments, and is expected to present new insights into the location and spatial composition of medical departments in consideration of the knowledge transfer paths within medical institutions.

Recent advances in optical-network technologies have led to the advent of broadband networks reaching 10 Gbps. The increase of available network bandwidth envisions wide-spread use of broadband applications such as uncompressed Internet HDTV, which would be a cutting-edge application for networked collaborations. Despite of breakthroughs in high-performance systems and networks, expensiveness blocks wide-range deployments of uncompressed Internet HDTV systems. In this paper, we propose a low-cost uncompressed Internet HDTV system and discuss its software architecture in depth. We conducted several network-based experiments utilizing a research network test-bed to evaluate the performance of the proposed system.

To offer insights in organizing professional development programs to promote teachers' substantial ongoing learning, this paper provides an overview of situative perspectives in terms of cognition as situated, cognition as social, and cognition as distributed. Then, it describes research findings on how mathematics teachers can enhance their knowledge and thus improve their instructional practices through participation in a professional development program that mainly provides opportunities to learn and analyze students' mathematical thinking and to perform mathematical tasks through which they interpret the understanding of students' mathematical thinking. Further, it shows that a knowledge of students' mathematical thinking is a powerful tool for teacher learning. In addition, it suggests that teacher-researcher and teacher-teacher collaborative activities influence considerably teachers' understanding and practice as such collaborations help teachers understand new ideas of teaching and develop innovative instructional practices.

Background: The burden due to cancers is an emerging public health concern especially in resource-limited countries like Nigeria. The WHO estimates that cancer kills more people than tuberculosis, HIV/AIDS and malaria combined. As people in Nigeria and other developing countries are beginning to survive infectious diseases, there is an observed epidemiologic transition to chronic diseases, such as cancers. In 2008, 75 out of 1,000 Nigerians died of cancer. Despite the rising incidence and public health importance, Nigeria lacks an organized and comprehensive strategy to deal with cancers. Materials and Methods: This article reviewed 30 peer-reviewed manuscripts on cancer care in four countries. It highlights the limitations to cancer care in Nigeria; due to lack of awareness, low health literacy, absence of organized screening programs, inadequate manpower (in terms of quality and quantity) as well as limited treatment options. Results: This review led to the formulation of a proposal for Nigerian National Cancer Policy, mainly drawn from effective strategies used in Canada, Brazil and Kenya. This is a vertical cancer program that is patient-centered with an emphasis on tobacco control and cancer disease screening (similar to Canada and Brazil). Additionally, it emphasizes primary cancer prevention (similar to Kenya). Its horizontal integration with other disease programs like HIV/AIDS will improve affordability in a poor resourced country like Nigeria. Capacity building for health professionals, hub-and-spoke implementation of screening services, as well as investment in effective treatment options and increased research in cancer care are essential. International 'twinning collaborations' between institutions in richer countries and Nigeria will enhance effective knowledge translation and improve the quality of patient care. Conclusions: A national cancer policy must be developed and implemented in Nigeria in order to overcome the present limitations which help contribute to the observed increases in cancer morbidity and mortality rates. Cancer control is feasible in Nigeria if the nation was to consider and employ some of the cost-effective strategies proposed here.

The purpose of this study is to provide preliminary data on strategies to create a domestic prestige brand based on Korean traditional designs. This study also deals with how to promote this brand around the world. The two points mentioned above will be accomplished by examining the characteristics of the brand '3.1 Phillip Lim' which succeeded in both design and marketing during a short period of time. The method of the study will be followed. Firstly, the basic design and philosophical background of Phillip Lim was investigated, after reviewing the global luxury market and current status of overseas expansion of Korean designers through paper study and antecedent workups. Secondly, for the practical stage, design characteristics and marketing strategies were reviewed with the collections of '3.1 Phillip Lim'. Three factors found in '3.1 Phillip Lim's design success are as follows: First, practical and simple designs using fabrics of high quality. Second, handcraft elements and interesting details that differentiates his design identity. Third, femininity expressed in the feminine silhouette and color. The marketing elements that made '3.1 Phillip Lim' as a successful brand are: First, differentiated positioning as a luxurious contemporary brand. Second, brand promotion through various collaborations. Third, the gradual expansion of women's, men's, kids' apparel to accessory, lingerie and the stable flagship stores. Thus, '3.1 Phillip Lim' has combined modern and classic styles using high quality fabrics and practical designs with unique details. Through it's differentiated marketing strategy targeting New York's market, which prefers popular 'luxury contemporary brand's rather than high-end luxury brands, this brand's creativity and commercial aspects contributed to make '3.1 Phillip Lim' into a luxury brand that represents New York fashion. Korean designers who seek to enter the global fashion industry should consider applying Korean traditional designs on global designs to make favorable products and localize these products according to regional characteristics.

Domestic agricultural and forest management suffers disturbances arising from rapid economic, social and environmental changes including climate change. Sustainable management has emerged as a key to overcoming these challenges. From the domestic and international viewpoint, we have identified mainly three (i.e. indicator, accounting, and ecological) approaches to sustainable management of agricultural and forest ecosystems. Compared to persistent investment in indicator and accounting approaches, we find the paucity of the domestic efforts in ecological approach. The latter approach can be facilitated based on the long-term meteorological and flux data including the ecosystem-level energy, matter and information flows, which have been monitored and managed by Korea Meteorological Administration, Rural Development Administration and Korea Forest Service. In order to keep up with vigorous international efforts toward sustainable ecosystem management, more interdisciplinary, multidisciplinary and transdisciplinary collaborations among diverse domestic sectors and institutes are essential.

The collaboration with members are very important things to manage the field organization in the building construction project. These collaborations are related with the communication in the organization, so the field organization ability could be advanced by improving the communication level. However, the research about communication in building construction field organizations has rarely studied. Therefore, the purpose of this study is to analyze the organizational factors to influence the communications in building construction field organizations. In this study, the leadership style of head managers and organizational cultural characteristics is determined the factors to influence the communication level by literature reviewing. The results of this study showed that the communication level is good when head managers in building construction site had an idealized influence style leadership and individual consideration style leadership. In addition, the good communicated field organizations had the higher characteristics of a consensus culture and development culture. This study is expected to help to improve the performance of the building construction field organizations.

This study examines the types and forms of underwear worn during the Joseon Dynasty period, and the purpose of this study is to apply the Joseon underwear design elements into designs of modern clothes, and make clothes that have practical use. In addition, it examines natural dyeing in the production of works, using a dye that contains tannin to increase color fastness. This study, first, looked into the types of female underwear during the late-Joseon Dynasty period through literature research and literature study. Second, the study chose artificial silk material (rayon), which was applied with dye containing tannin, and then with indigo (Jjok) and a different dye. Also, the study tested color fastness by washing the material, and rubbing fastness was tested if the material was either dyed with indigo. if it was dyed first with dye stuff containing tannin, and then with indigo dyeing color. Third, using the underwear types in the Joseon Dynasty period, the study developed and produced a dress, a skirt and pants that could be worn in modern life on a daily basis by applying Mujigi-chima (underwearskirt), Dan-sokgot (slip), Salchang-gojaengi (loosedrawers) and Sok-baji (bloomers) forms. Dresses applying underwear skirt using naturally-dyed artificial silk, dresses applying Salchang-gojaengi, dresses applying Dan-sokgot, skirt without a crotch designed in the form of pant swith an open crotch, and pant skirt with a crotch-applying pants with an open crotch were produced. In the future, hopefully, various studies of collaborations of Korean traditional clothing, and natural dyeing will continue to kee) the tradition alive.

The COREA (COsmic ray Research and Education Array in Korea) project aims to build a ground array of particle detectors distributed over Korean Peninsular, through collaborations of high school students, educators, and university researchers, in order to study the origin of ultra high energy cosmic rays. COREA array will consist of about 2000 detector stations covering several hundreds of $km^2$ area at its final configuration and detect electrons and muons in extensive air-showers triggered by high energy particles. During the intial phase COREA array will start with a small number of detector stations in Seoul area schools. In this paper, we have studied by Monte Carlo simulations how to select detector sites for optimal detection efficiency for proton triggered air-showers. We considered several model clusters with up to 30 detector stations and calculated the effective number of air-shower events that can be detected per year for each cluster. The greatest detection efficiency is achieved when the mean distance between detector stations of a cluster is comparable to the effective radius of the air-shower of a given proton energy. We find the detection efficiency of a cluster with randomly selected detector sites is comparable to that of clusters with uniform detector spacing. We also considered a hybrid cluster with 60 detector stations that combines a small cluster with ${\Delta}{\iota}{\approx}100m$ and a large cluster with ${Delta}{\iota}{\approx}1km$. We suggest that it can be an ideal configuration for the initial phase study of the COREA project, since it can measure the cosmic rays with a wide range energy, i.e., $10^{16}eV{\leq}E{\leq}10^{19}eV$, with a reasonable detection rate.
