제어공학에서 흔히 표준 모델이라고 불리우는 플랜트 모델은 여러 부 시스템이 서로 결합되어있는 복잡한 시스템을 단순화시킨 모델이다. 이 모델은 수학적으로 간략하게 표시된다는 장점 때문에 다변수 시스템의 최적 제어에 많이 쓰이고 있다. 그러나 이 모델은 수학적인 전개에는 편리하지만 물리적으로 판이하게 다른 신호군 즉, 외란 및 측정 잡음과 기준 입력 신호를 하나의 신호군으로 처리하는 약점이 있다. 실제로 이 구조로는 입력 추종 문제를 자유롭게 처리할 수 없는 경우가 있다. 본 연구에서는 이러한 문제를 개선하기 위하여 외란 및 측정 잡음과 기준 입력을 분리하여 처리할 수 있는 2자유도 제어기 구조를 제시하였다. 제어기 형태는 위너-호프 제어기로 주파수 영역에서 다 변수 시스템에 대한 최적 설계를 가능하게 한다.

German architect Hans Scharoun (1893-1972) has long been known as an Expressionist Architect, but recent scholarships reveal that his architectural pieces represent a profound idea of modern functional building. In this context, his architectural tendency can be constructed as an advanced functionalism. In the early twentieth century Germany, many young architects were not given chances to build due to economic hardship after World War I, and they were naturally led to imagery sketch designs for future architecture. Scharoun began with utopian fantasies as one might easily notice through his watercolor paintings in the Glass Chain period, but further developed his vision into a more concrete idea on organic building which he believed to be a modem functionalism. This paper intends to exemplify Scharoun's modern functionalism through a detailed analysis of his design of Weissenhofhaus presented at Stuttgart Deutscher Werkbund Exhibition in 1927. Weissenhofhaus is often rebuked for its expressionist qualifies by famous critics such as Sigfried Giedion and Nikolaus Pevsner, but the house also suggests other possibilities within the Modern Movement in Architecture. In particular, Weissenhofhaus is chosen for its historical importance linking two world war eras in German modern architecture.

Understanding cultural diversity is tremendously important to academia and businesses. The Central Asia is strategically important to Korea specially for businesses. Of the about two million foreign residents living in Korea, Central Asians take fifth place and the region is a home of 300,000 Korean decedents called "Koryoin." With its increasingly recognized the potential and relevance, the former Soviet region has gained importance for businesses and academia in South Korea. This study uses the Hofstede's classifications to exploratorily analyze the relationship between Central Asian people's experience of Korean products and services and their loyalty to Korean products and services.

Objectives: The purpose of this study was to estimate the prevalence of food allergies and find out food allergens. Methods: Questionnaires were completed by 2,415 subjects in D city, among whom 452 subjects believed that they had food allergy. Skin prick tests were performed on these subjects. The data were analyzed using SAS Version 9.0 and ${\chi}^2$-test. In addition, several recent studies were reviewed. Results: The prevalence rate of food allergic symptoms was 25.6% in males and 25.8% in females, respectively. The positive rate of skin prick tests among those who were allergic to any of 14 food items was 21.4% in males and 14.7% in females(p=0.018). Therefore, it was estimated that the prevalence rate of food allergy was 5.0% in males and 3.6% in females. It was shown that the major food allergens were hop, shrimp, lobster, oyster and egg(whole) in males, and egg(whole), hop, oyster, and pork in females, respectively. The prevalence in recent studies ranged from 1 to 35%. Major food allergens were milk, egg, nuts, fish, shellfish crustacean and fruits/vegetables. Conclusions: In order to provide effective care for food allergy, it is essential to find out the prevalence of food allergies and food allergens.

The hop alpha-acid content prediction model developed with meteorological elements in Hoeongseong was Y=28.369-0.003X$_1$＋1.558X$_2$-1.953X$_3$-0.335X$_4$-0.003X$\sub$5/-0.119X$\sub$6/, with MSEp of 0.004, Rp$^2$ of 0.9987, Rap$_2$ of 0.9949 and Cp of 7.00. The total sunshine hours (X$_1$), the maximum temperature (X$_3$) and the total precipitation (X$\sub$5/) at flowering stage. the maximum temperature at flower bud differentiation stage (X$_4$) and the maximum temperature at cone ripening stage (X$\sub$6/) influenced on hop alpha .acid content as decrement weather elements. The maximum temperature at cone development stage(X$_2$) effected on ${\alpha}$-acid content as increment weather element.

지난해 공정거래위원회 발표에 따르면 500개 이상의 가맹점을 가진 프랜차이즈만해도 10여 개에 이르며 일일 60여만 마리의 닭이 소비되는 국내치킨 시장 규모는 약 5조 원에 육박한다고 한다. 국내 치킨시장은 혼돈의 시대를 맞고 있다. 전국 5만여 개의 치킨체인점과 개인매장이 운영중에 있으며 다른 외식 상품에 비해 저렴하고 새로운 메뉴의 개발로 소비자의 다양한 기호를 만족시키고 있는 국내 치킨시장은 소비자들의 크나큰 인기로 급성장을 이루었으나 반면 수많은 브랜드가 쉽게 출시되고 소비자의 입맛을 맞추지 못하면 곧바로 퇴출되는 구조로 변화되었다.

더스틴 호프만이 아서 밀러의 대표작 '세일즈맨의 죽음'의 주인공 윌리 로먼 역할을 연기하는 것을 보면서 목이 메였던 적이 있다. 그 당시 내 남편과 아버지, 그리고 아들은 세일즈 맨이었다. 다행이도 내인생과 결부되어 있는 남자들은 불운했던 윌리로먼 보다는 훨씬 일을 잘 해냈다. 그러나 주문을 따내지 못하거나 결코 얘기해 준적이 없는 어떤 것에 대해 이제 막 알게되어 낙심하여 집으로 돌아오는, 지친 세일즈맨의 그 모습만은 유감스럽게도 너무나 흡사했다. 고객을 끌어들이고 끌어들인 고객을 유지한다는 근본 목표를 달성하고자 하는 오늘날의 외판원들은 윌리로먼이 알지 못했던 기술적 지원을 받을수 있다.
