Programmable Metallization Cell (PMC) is a memory device based on the electrolytical characteristic of chalcogenide materials. PMC components of Ge-Se doped with Ag ions were studied with help of the previous studies and copper was used for metallic ions taking into account of economy of components. In this study, we investigated the nature of thin films formed by photo doping of Cu ions into chalcogenide materials for use in solid electrolyte of programmable metallization cell devices. We were able to do more economical approach by using copper which play role of electrolyte ions. The results imply that a Cu-rich phase separates owing to the reaction of Cu with free atoms from chalcogenide materials.

A literature review was conducted to survey informations available on the welding metallurgy of aluminum alloys and its effect on fusion weldability, especially on solidification cracking and pore formation. Solidification cracking behavior of Al weld is a complicate matter as compared to other high alloys, where a relatively simple Fe-X(most detrimental elements S, P, B, Si, etc) binary diagram can be successfully applicable. Both additive and synergistic effects of elements should be considered together. A same element play a different role from system to system. Porosity, caused by hydrogen contamination of the weld is one of the most troublesome welding problems. The primary sources of hydrogen are believed to be an absorbed moisture on the filler metal or base metal and in the shielding gas. It is extremely important that reliable quality-control procedures be employed to eliminate all possible sources of hydrogen contamination. Selection of proper process and parameters is sometimes more important than controlling of alloying elements in order to make a defect-free weld.

With the steady rise in global popularity of the Korean music group BTS, the South Korean government and surrounding industries have swiftly begun utilizing their image and international recognition for specific nation branding purposes. While K-pop soft power strategies are not novel to the South Korean state, what is new is the rapid speed at which BTS have become a beacon for South Korean culture, language, and symbolism in the international arena. However, few scholarly works have sought to investigate the role fans have played in this heightened position for the group as state representatives, with minimal research conducted into the work fans do within the framework of ARMY fan culture. This paper will thus aim to fill the gap in scholarship on ARMY as an organized labour network, focusing on the role fans play as labourers in online spaces that work to promote, disseminate, and cultivate wider recognition for BTS as artists. Through the conjunct engagement of a political economy framework and theories of participatory culture, this paper will explore the manner through which the free labour of ARMY, premised on affect, has constructed the fandom as active agents of soft power alongside BTS themselves.

Wood Plastic Composite(WPC) has been introduced as a new constructional material in Europe and North America. The maintenance-free durability against weather was accepted by customers and the environment-friendly merits ignited the abrupt increase of market size. Domestic major companies have kicked off the WPC business at the market of outdoor constructional materials. Due to the high contents of natural wood fiber, the production equipments should be modified to remove the moisture, to prevent thermal degradation and to promote output rates. Materials including functional fillers play a critical role in rheological properties, which affects the physical and mechanical properties of the last products. More research might be performed for synergy effects combined by various academic fields from mechanical and chemical engineering to polymer process and material science.

Sero-epidemiologic survey has been carried out to establish serologically the presence of hantavirus in areas of South Africa. The survey was oriented to search natural infection in both of humans and wild rodents and involvement of human disease. The normal human sera were collected from the residents in urban and rural areas of Western Cape, and rural area of Eastern Cape province. The rodent sera came from various species of rodents trapped in Northern Cape and Western Free provinces. The patient sera were selected from the patients of renal failure, pulmonary syndrome and pyrexia of unknown origin (PUQ) according to diagnostic chart among the patients hospitalized in major hospitals of Cape Town area. The sera were screened and titrated by IFA test using antigens of Hantaan (HTN), Seoul (SEO), Puumala (PUU), and Prospect Hill (PH) viruses primarily. Positive cases were subjected to differential IFA test using HTN, PUU and PH antigens and plaque reduction neutralization test for further confirmation. Anti-hantavirus antibodies were detected from 2 of 352 rural, 1 of 172 urban residents of E. Cape, and 5 of 118 rural, 5 of 368 urban residents of W. Cape. The antibody was also demonstrated from 5 of 221 wild rodents, and it was appeared that 2 different species, Aethomys namaquensis and Tatem leucogaster, are involved. Among 318 patients tested, 3 who were diagnosed as chronic renal failure, acute respiratory distress syndrome (ARDS) and glomerulonephritis were proved to be positive. The reaction patterns obtained from all of these positive sera were distinct from hantaviral sero-patterns ever established. This result suggests that new viruses may exist in this area and play an possible etiologic role in human disease. The feature of serologic survey on anti-hantavirus antibody demonstrable newly from African wild rodents which are different from reservoir species in other continents elicits a conjecture that the virus may be different from known hantaviruses ever found. This fact also suggests that an expanded role in etiologic involvement with other unknown human diseases by newly emerging hantaviruses may be possible in this areas.

1960년대의 새로운 연극그룹들의 작업 성향을 요약해 보면 크게 두 가지로 정리해 볼 수 있을 것 같다. 첫째 이들은 연극에서 아이덴티티를 추구하고자 하였다는 점이다. 둘째는 기존의 공간언어에 구체적인 반기를 들어 그 모든 것들에 충격을 주어 파괴시킴으로써 인간내면의 강렬하고 즉각적인 폭발을 일으키는 연극을 창조하길 추구했다는 점이다. 그들은 스타니슬라브스키가 추구했던 연기를 초월해 연기는 새로운 인간을 이식시킨다기보다는 배우의 이면에 숨겨져 있는 자신을 개발하거나 가면을 벗기는 것이 필요하다는 인식에 도달해 배우의 첫 번째 과제는 자신을 두르고 있는 껍질을 벗겨 제거하는 것에 있다는 공통된 의지를 나타냈다. 그리하여 그들은 그들의 이상인 자신의 껍질을 벗기는 연기를 구체적으로 실현 할 수 있는 도구란 무엇인가에 대해 고심하게 되는데 그들은 결국 그 해답을 '즉흥연기'에서 찾았던 것이다. 그중 한 가지는 배우의 무의식세계를 자극하여 배우 내면에 숨겨져 있는 본능적인 정서를 분출시키자는 것이다.
