Regular maps and hypermaps are cellular decompositions of closed surfaces exhibiting the highest possible number of symmetries. The five Platonic solids present the most familar examples of regular maps. The gret dodecahedron, a 5-valent pentagonal regular map on the surface of genus 5 discovered by Kepler, is probably the first known non-spherical regular map. Modern history of regular maps goes back at least to Klein (1878) who described in [59] a regular map of type (3, 7) on the orientable surface of genus 3. In its early times, the study of regular maps was closely connected with group theory as one can see in Burnside’s famous monograph [19], and more recently in Coxeter’s and Moser’s book [25] (Chapter 8). The present-time interest in regular maps extends to their connection to Dyck\`s triangle groups, Riemann surfaces, algebraic curves, Galois groups and other areas, Many of these links are nicely surveyed in the recent papers of Jones [55] and Jones and Singerman [54]. The presented survey paper is based on the talk given by the author at the conference “Mathematics in the New Millenium”held in Seoul, October 2000. The idea was, on one hand side, to show the relationship of (regular) maps and hypermaps to the above mentioned fields of mathematics. On the other hand, we wanted to stress some ideas and results that are important for understanding of the nature of these interesting mathematical objects.

Purpose: This study was conducted in commemoration of the 40th Anniversary of the Korean Academy of Community Health Nursing [KACHN]. Methods: Primary and secondary sources were collected and analyzed to show changes that KACHN has experienced. Results: In the 1970s it made the annual meeting regular and began research presentation. In the1980s regular symposiums were activated and as a result the academy could publish its own journal from 1989. In the 1990s the boards were selected from locals by turns and lots of papers and teaching materials were produced from collaborate researches of the members. In the 2000s, the journal was selected by the National Research Foundation in Korea and the academy began regular Korea-Japan Community Health Nursing Conference and hosted the 5th ICCHNR. Conclusion: In spite of great development, KACHN has new challenges. The number of members has increased so much that there are a few academies specialized in some fields of community health nursing. They have made the members' interest and loyalty weaker than during the pioneer days. KACHN should take the new role as a leader of international community health nursing research as well as the old role as a leader of Korean community health nursing research.

본 연구는 현재 방송되고 있는 TV 건강프로그램에 대한 노인들의 인식, 시청행태 및 만족도를 파악하여 건강행위 실천에 미치는 영향을 조사하고자 2008년 3월 17일부터 3월 28일까지 경상북도 포항시에 거주하는 노인 293명을 대상으로 설문조사 하였으며, 분석한 결과는 다음과 같다. TV 건강프로그램에 대한 최근 1개월간의 시청경험은 86.3%이었고, 학력, 비만도, 병력이 시청빈도에 유의한 차이를 보였다. 대상자의 건강행위 실천도는 62.1%가 높다고 하였고, 17.7%가 낮다고 하였다. 건강행위 실천확률에 유의하게 영향을 미치는 요인은 성별, 건강관심도, 시청경험이었으며, 남자가 여자보다 1.78배, 건강관심도가 있는 경우가 없는 경우보다 3.3배, 시청경험이 있는 경우가 없는 경우보다 6.1배 건강행위 실천도가 높았다. 노인들의 TV 건강프로그램에 대한 인식은 긍정적이었으며, 시청빈도가 높을수록 건강행위 실천이 높았다. 또한 노인들의 건강프로그램에 대한 높은 시청률은 건강프로그램 내의 정보에 노출될 기회가 많음을 의미한다. 따라서 TV 건강프로그램은 노인들의 요구에 충족할 수 있는 올바른 건강정보를 제공하도록 노력하여야 할 것으로 생각된다.

Throughout the history of architecture, sometimes the main focus of design was determined by a particular visual representation method, and other times a particular form of visual representation method was required by perception of a particular architectural issue or an architectural form or idea. That is why the visual representation method of architects becomes an important means of reading the flow of idea and thinking behind architecture. This study is an investigation on the relation between architectural thinking and visual representation method expressed through the conceptual drawings by avant-garde architects of the 1970s and 80s, a period of the emergence of postmodernism. Rather than proving the objective reality regarded important by traditional architectural drawing, attempts are made to express the design concept in which the project has its base. Such interpretation and explanation regarding the concept become the main interest of the drawing. It is not that the architecture itself was not expressed in the contents, but it may not be the main subject of expression in the drawing. The value of architectural drawing recovers its value as an art work in itself, as a means of communication, and as an important conceptual tool in the design process. It can be seen that the visual representation method in postmodern architectural drawings is breaking free of the traditional objective depiction of matter and is changing and developing as a design tool of the architect.

In textile industry of $21^{st}$ century, to develop materials and designs in fashion industry is being recognized widely as an urgent problem. In other words, the reality is that we must offer scarcity value and unique materials, and make a positive effort in a time when consumers' individuality appeals and an interest in fashion becomes higher. Felt is not only the oldest material in human history, but also a technique, and its applications are being handed down broadly. I have made various materials based mainly on a traditional felt technique using merino wool and nuno felt technique felting merino wool to cotton gauze. In nuno felt thing, I could observe that as wool and cotton was created as a single composite material, each material's aesthetic, sensuous, functional and emotional description became much more diversified. The purpose of this study is to produce fashion materials using materials with rich texture to meet the consumers' preference and diversity which are increasingly individualized, to design them and to seek possibility of developing differentiated wool materials which can satisfy the consumers' individuality demand and preference.

A museum represents a country's history, culture and life. With the development of science and technology, museum is no longer simply a space that concentrates on display and management of the collection but a space for education that visitors can directly experience and feel interest. The purpose of the present study is firstly through theoretical approach and research to grasp the status quo of the exhibition of the National First Level museums located in Beijing, which is the capital city of the People's Republic of China. Secondly, by analyzing the themes of exhibition and the exhibition presentation methods, it is aimed at finding out the problems of the status of museums in China so as to seek the requirements and the direction of improvements. Through this research, it is confirmed that in order to induce more active exhibition participation, the museums should expand the number of direct experience style exhibition presentation methods. Also, the museums in China need technical introduction of new cutting-edge exhibition medium so as to meet emotional demands of spectators and make the most ideal experience environment. Furthermore, it is confirmed that the development of new exhibition themes and the improvement of the museums in aspect of management and operation are necessary.

21세기 화두를 한마디로 말하면 건강일 것이다. 건강을 위해서 각종 운동 방법 및 운동기구와 건강 보조식품의 판매가 급성장을 하고 있으나, 우리가 섭취하는 음식 즉 식단에 대해서는 무관심하다. 예전에 비해 먹거리인 식재료는 매우 풍부해졌으나 영양 불균형은 오히려 증가하는 추세이며, 잘못된 식생활 습관으로 발생하는 만성질환인 성인병과 생활 습관병의 발생은 심각한 사회적 병리현상으로 나타나고 있다. 따라서 식품도 이젠 맛, 영양을 강조하던 단계에서 인체의 생리적 기능 항진과 질병의 예방 및 치료가 가능한 기능성 식품으로 발전하고 있다. 약선은 동양철학 및 동양 의학의 원조라고 할 수 있는 중국의 의학과 화려한 음식 문화가 만들어낸 것으로 음식에 한약재의 유용성분을 넣어 기능성을 살린 먹거리로 한의학의 약식동원을 기본 이론으로 하고 있다. 중국약선에서는 식품을 차거나 시원한 식품인 한량(한량), 따뜻하거나 뜨거운 (온열) 식품, 즉 한(한), 량(량), 온(온), 열(열) 4가지로 분류하고, 쓴맛(고), 단맛(감), 매운(신), 짠맛(함), 신맛(산) 등 5가지 기본맛으로 식품을 구분하고 있다. 약선식품의 작용은 질병의 예방과 신체 장기를 자양하거나, 기혈, 골격, 피부 등을 자양하고, 노화방지와 질병의 치료작용이 있다. 우리나라에서는 일부 궁중음식원과 산사 음식에서 약선 개념을 도입하고 있으나 아직까지 체계적인 이론 정립과 연구는 미비한 실정으로 본 연구를 통해 궁중의 약선 관련 문헌을 고찰해 보고, 우리나라 실정에 적합한 약선의 도입과 연구발전에 필요한 기본자료로 제공하고, 약선을 이용한 새로운 건강 기능성 조리개발에 도움이 되고자 하였다.

The immune response to any stimulus is complex, requiring coordinated action by several types of cells in a tightly regulated sequence. Thus, a physical stress such as exercise may act at any number of points in the complex sequence of events collectively termed the immune response. Although exercise causes many propound changes in parameters of immune function, the nature and magnitude of such changes rely on several factors including the immune parameters of interest; type, intensity, and duration of exercise; fitness level or exercise history of the subject; environmental factors such as ambient temperature and humidity. Although regular moderate exercise appears to be important factor for increasing immunity, Athletes are susceptible to illness, in particular upper respiratory track infection, during periods of intense training and after competition. In addition, in elite athletes, frequent illness is associated with overtraining syndrome, a neuroendocrine disorder resulting from excessive training. Through this paper, we want to investigate the effects of exercise on the immunosuppression such as exercise induced lymphopenia, asthma, anaphylaxis, URT (upper respiratory track), and TB (tuberculosis) infection. and also, we want to suggest a direct mechanism, protection and therapy of exercise induced immunosuppression.
