In this article, we proposed a novel technique to fabricate cell‐culturing scaffold, that is, the hollowcylinder‐ grain assembly technique. This technique uses hollow cylindrical particles with sub‐mm thickness. Firstly, we fabricate PCL (polycaprolactone) hollow cylinder with sub-mm thickness using lab-made stainless steel mold. After that, we put the above-mentioned fabricated particles into a metal mold of which temperature could be controlled with hot plate and heat insulation system. PCL particles in the metal mold could be assembled together without severe collapsing under adequate temperature and time. Consequently, we could fabricate scaffold or foam structure with interconnected‐porosity and observed surface of cross section of fabricated scaffold by SEM.

최근 많은 건축물들이 서로 다른 두 산지 사이에 건설되고 있는 실정이다. 이런 경우에는 건축물의 안전성을 확보하기 위해 지형에 의해 풍속이 증가되는 효과를 고려해야한다. 두 산지 사이의 골바람효과에 의한 풍속증가현상의 특성을 조사하기 위하여 풍동실험을 수행하였다. 실험에는 산의 경사각이 변하는 4가지 종류의 간단한 골짜기 모델을 사용하였고, 평균풍속의 흐름과 수평방향의 난류강도를 중점적으로 측정하였으며, 산의 경사각과 속도의 증가의 관계가 조사되었다. 평균풍속의 경우에는 증속효과와 풍향에 따라 변화하는 경향이 뚜렷하였고, 난류강도는 산지형의 하부에서 골짜기의 풍속증가 효과에 의해 감소하는 경향을 나타냈다. 이 연구결과는 두 산지 사이의 골바람 효과에 의한 풍속증가 효과를 평가할 때 기본적인 자료로 활용할 수 있을 것이다.

Presently, the most promising family of lead-free piezoelectric ceramics is based on K0.5Na0.5NbO3(KNN). Lithium, silver and antimony co-doped KNN ceramics show high piezoelectric properties at room temperature, but often suffer from abnormal grain growth. In the present work, the (Ba0.85Ca0.15)(Ti0.88Zr0.12)O3 component, which has relaxor ferroelectric characteristics, was doped to suppress the abnormal grain growth. To investigate this effect, Lead-Free 0.95(K0.5Na0.5)0.95Li0.05NbO3-(0.05-x)AgSbO3-x(Ba0.85Ca0.15)(Ti0.88Zr0.12)O3[KNLN-AS-xBCTZ] piezoelectric ceramics were synthesized by ball mill and nanosized-milling processes in lead-Free 0.95(K0.5Na0.5)0.95Li0.05NbO3-(0.05-x)AgSbO3 in order to suppress the abnormal grain growth. The nanosized milling process of calcined powders enhanced the sintering density. The phase structure, microstructure, and ferroelectric and piezoelectric properties of the KNLN-AS ceramics were systematically investigated. XRD patterns for the doped and undoped samples showed perovskite phase while tetragonality was increased with increasing BCZT content, which increase was closely related to the decrease of TO-T. Dense and uniform microstructures were observed for all of the doped BCZT ceramics. After the addition of BCTZ, the tetragonal-cubic and orthorhombic-tetragonal phase transitions shifted to lower temperatures compared to those for the pure KNNL-AS. A coexistence of the orthorhombic and tetragonal phases was hence formed in the ceramics with x = 0.02 mol at room temperature, leading to a significant enhancement of the piezoelectric properties. For the composition with x = 0.02 mol, the piezoelectric properties showed optimum values of: d33 = 185 pC/N, kp = 41%, Tc=325˚C, TO-T=-4˚C.

Today this present of the GuanYu worship was changed into the cultural phenomena in china and all of the world chinese area. That is called a cultural phenomena of the GuanYu worship. This cultural phenomena of GuanYu Worship have many special meaning in the part of chinese traditional culture and society. We believe that the comprehensive understanding about the cultural phenomena of GuanYu Worship will bring us the right direction to understanding of the "GuanYu Culture" and the "SanGuoZhi Culture" in China.
It is well known that modified 9Cr-1Mo steel has a low thermal expansion and high thermal conductivity with excellent high temperature properties compared to austenitic stainless steel. For these advantages, the steel is very popular for the boiler tube of thermal power plants. Normalizing is commonly utilized to obtain martensite in this steel, which shows an unusual toughness for martensite. However, some accidents related to this steel have been reported recently, opening the necessity for further study. As a particular behavior of the steel, an abrupt drop of the impact value has been identified upon tempering at 750˚C for about 1 hour. It is well known that Fe3C forms during autotempering and turns to Cr2C at an early stage and then transforms to Cr23C6. In this study, the cause of the abrupt drop of the impact value was investigated with an impact test, microstructural observation, nanodiffraction and phase analyses using instruments such as optical and transmission electron microscopes (TEM) with an extraction carbon replica of the carbides. The analyses revealed that the M2C that formed when retained for about 1 hour at 750˚C causes a drastic decrease in the mechanical properties. The sharp drop in mechanical properties, however, disappeared as the M2C transformed into M23C6 with longer retention.

Although Guleopdo is small island of only 1.71 ㎢, the endangered butterfly species, Argynnis nerippe, is abundant there. This study was carried out to estimate the abundance of A. nerippe in Guleopdo, using quadrate, mark-recapture, and line-transect methods. Although the study was insufficient, the population size was estimated at 4,467 to 6,700 larvae and approx. 1,000 adults. A. nerippe was the most abundant among butterfly species in Guleopdo, and it comprised 32% of the total butterflies. A total of 28 butterfly species were observed in this study, and 3 species of these species were migrating species. When the abundance of A. nerippe throughout the country during the period from 1938 to 2010 was studied, we found that it decreased abruptly in the 2000s. Presently, A. nerippe inhabits a few locations in the mid-northern region and western islands. The relatively high numbers of A. nerippe in Guleopdo was due to conservation of natural grasslands and grazing of livestock, which provides adequate habitat for this species.

Our society is changing rapidly to a multicultural society, but if we disrespect migrant workers, married immigrants and multicultural family children, who came from foreign countries and have been incorporated as our society members, only because of their different skin color, appearance and language and treat their culture with prejudice, such racial discrimination will cause cultural conflicts and undermine the stability of Korea society. In order for them to be the true members of our society, we need to give much consideration not only to national policies but also to social consensus and school education for minimizing their social and psychological conflicts with our culture and reduce social consumption resulting from such conflicts. Culture refers to internal ways of thinking, external behaviors, etc. shared by a specific group through a long process of life experience. Traditional culture is formed and developed collectively by a life community, and reflects their production activities and sentiments, so it has unique characteristics distinguished from the culture of other groups. Traditional culture defines the order and sentiment of life in the group members, and gives a sense of belonging to the community so that the members have identity. Multi‐culture originally meant the coexistence of diverse native cultures retained by minority races and people with their originality preserved rather than being integrated into the dominant culture in multi‐racial and multi‐ethnic countries like the U.S. These days, however, it has an expanded meaning, that is, respecting the originality of minority cultures and pursuing the coexistence of such cultures in the native culture of the mainstream society. In the process that a nation develops its culture, it may receive foreign cultures and change its traditional culture. What is important in this process is developing new culture without losing traditional culture. If traditional culture declines and fades away, overwhelmed by powerful foreign culture, it cannot be desirable succession and development of culture. Multicultural education originated from education for understanding the national background and cultural contributions of American immigrants in the late 1920s, and is also related to the term ‘national studies’ for enhancing the self‐identity of minority peoples in the early 1960s. From the late 1960s, the term ‘multiethnic education’ was used to mean that all children should learn various cultures in the U.S., and in the 1970s, the term ‘multicultural education’ began to be used as its meaning today. Banks, a representative scholar in multicultural education, defined multicultural education as “A reform movement for giving peoples from diverse genders, languages, social classes, races and groups equal opportunities for learning,” and Bennett explained it as “an approach to teach and learn based on democratic values and beliefs in order to promote cultural diversity in a culturally diverse society or an independent world.” Moreover, Morrison said that multicultural education is education for preparing students to understand, perceive correctly and respect others from different races, genders, socio‐economic statuses, languages and cultural backgrounds, and ultimately to live, communicate, and act for common goals in multicultural society.In this way, multicultural education is a concept based on diversity and pluralism as well as on democracy, equality, human rights, social justice, etc. Furthermore, targeting not only children from migrant worker, married immigrant and multicultural families with minority culture but also all students from mainstream culture, it aims to help them recognize that our society is now entering into a multiethnic and multicultural society and be able to develop harmonious relations in the multiethnic and multicultural society. In other words, multicultural education is to emphasize and teach that, in the present age of globalization, groups of different culture, race and society should maintain their own native language and culture and, at the same time, coexist with the mainstream culture and make various contributions to the society. Multicultural education can be divided into ‘multicultural education for mutual understanding among cultures,’ ‘education responding culturally,’ ‘cross‐cultural education,’ ‘cultural pluralism of education,’ ‘multicultural education as human experience,’ etc. Moreover, multicultural education has been developed through processes such as multiple culture education, international understanding education, anti‐prejudice education, and globalization education, and may share conceptual denotations with human right education, anti‐war peace education, and ecological environment education. In other words, multicultural education intends to help students understand the diversity of people with various backgrounds in terms of culture, race, gender and social class, have positive attitude and perception toward the diversity, admit cultural differences from the viewpoint of cultural relativism, and acknowledge values in other cultures. It was from the 7th National Curriculum that Korea began to take interest in multicultural education. At that time, people began to recognize the importance of international understanding education and global citizen education and the necessity to understand culture diversity in other countries. In response to these demands, the 7th National Curriculum introduced some contents for international understanding and multicultural understanding mainly in subjects related to foreign languages and social studies. Later the 2007 Revised National Curriculum reflected multicultural education in all the subjects. That is, the Generals of the 2007 Revised National Curriculum suggest multicultural education as one of 35 interdisciplinary themes of learning, and furthermore, direct that it should be reflected in the development of textbooks. The Korean government is executing various multiculturalist policies to cope with transition to multicultural society and resultant problems. That is, as the number of multicultural family children attending elementary and secondary schools is increasing with the expansion of married immigrants and migrant workers and there should be strengthened educational support to them, the Ministry of Education and Human Resources Development made Plans to Provide Educational Support to Multicultural Family Children but most of the contents aim to help foreign workers and married immigrants adjust themselves to racially homogeneous Korean society by learning Korean language and traditional culture. This suggests that while our society is changing rapidly to a multicultural society but multiculturalist policies and multicultural education are still insisting on Koreanization through infusing the myth of homogeneous race and culture and forcing assimilation to Korean national culture. What is more, through its Study on Teaching‐Learning Support for Multicultural Education, Korea Institute of Curriculum and Evaluation suggested the objectives of multicultural education as follows: first, to understand cultural diversity and differences and strengthen cultural identity; second, to develop tolerance of understanding and respective native culture as well as other cultures and the attitude of contributing to the recreation of culture; and third, to promote a sense of community, the qualities of democratic citizen, peaceful settlement of conflicts, cooperative attitude, respect for human rights, and social justice. In order to achieve these goals, in addition, it proposed programs: first, to provide opportunities to experience other cultures; second, to understand the own traditional culture; and third, to promote international understanding. However, these proposals focus on education for multicultural family children, so are not sufficient for giving multicultural education to ordinary students. In multicultural society resulting from globalization, our education should seek mutual understanding and coexistence of different languages and cultures of diverse races and people rather than the transfer of traditional culture based on our homogeneous language and race. Moreover, education in multicultural society should place emphasis more on the majority’s understanding and tolerance of minorities’ race, people, and culture than on assimilation of immigrants from foreign countries to the mainstream society. Accordingly, though already late, Korean people should also admit ‘multiculturalism’ as a basic attribute of the society instead of clinging to the purity of language and people, and receive and respect cultural diversity for the coexistence of multiple cultures in one society or one country. That is, school education should include not only education for multicultural family students to understand our language and culture as the mainstream but also education for the majority of our society to understand and tolerate the cultures of minorities including immigrants from foreign countries, half‐blooded children from them, and North Korean defectors. The fundamental objective of Korean education is “to build up the people’s character under the ideology of Hongikingan (devotion to the benefits of mankind) and to equip individuals with abilities for independent life and qualities as a democratic citizen so that they may be able to lead a noble life and to contribute to the development of democratic state and the realization of the co‐prosperity of mankind.”
Co‐prosperity of mankind is impossible without overcoming nationalism, which gives the top priority to the superiority and benefits of my own country. That is,the true co‐prosperity of mankind is possible only when we acknowledge and respect differences in history, culture, religion, language and customs between my people and others. This means that, in order to educate people required in the age of globalization, even the education of traditional culture should concentrate on raising global citizens from the viewpoint of multiculturalism.
When a fire breaks out, it is difficult to find out the causes of the fire, because combustible things around fire scene are usually burnt away. Among many causes of fires are electronic wires, this thesis deal with the destroyed sheath of electronic wires caused by fire. It was studied with the use of measurement devices focusing on the distinctions of wires and conductors. This study especially emphasized the process of deterioration, burning pattern, and composition of electronic wire conductor. It also has a phenomenological approach to the distinctive cause of fire by some partial force. The fire prevention methods have been suggested through the analysing results of fire patterns. This study is expected to be a useful material for analyzing various electrical fires.
