The purpose of this study is to find differences in dietary patterns through menu analysis by economic status. The data was obtained from the 1998 and 2001 National Health and Nutrition Survey of Korea. The main variables were economic status, sex, and area by urbanization. The economic status was classified into low, middle, high, and top classes using a poverty line based on the 1998 and 2001 minimum standard cost of living. The areas were divided into metropolis, small city, and rural areas. The dishes of 3 meals were classified into 29 categories by cooking method. The most frequent pattern was "rice + soup + kimchi". The frequency of this Korean basic dietary pattern was the lowest in the top income class and metropolis areas, while the highest in the low income class and rural areas. The frequency of Korean recommended dietary pattern, that is, "rice + soup or stew + kimchi + side dish" was the highest in the top income class. The metropolis group preferred side dishes using meat and a cooking method that saved time, but the rural group preferred side dishes using vegetables and cooking methods that take a longer time. In comparison of dietary pattern between male and female by economic status, the higher economic status, the male's dietary patterns showed more side dishes than those of female. But the main side dish was kimchi in male low class. Consequently, the major dietary pattern in Korea is rice-style, though the western pattern is increasing in the top income class, especially in metropolis areas. Therefore, to make a better dietary pattern, we should develop and spread low-priced recipes of various side dishes and teach financial skills such as ability to make a food budget for lower income classes. Also, we should emphasize the importance of the balance between meat and vegetables and traditional diet and western diet for the top income class, especially in the metropolis areas.

One of the main features of the 7th revised national curriculum is the implementation of a 'Differentiated Curriculum'. Differentiated Curriculum is often interpreted as meaning the same as 'tracking' or 'ability grouping' in western countries. In the 7th revised curriculum, mathematics is organized and implemented by 'Level-Based Differentiated Curriculum'. To develop mathematics textbooks and teaching-and-learning materials for Differentiated Curriculum, the ideas of 'Enriched and Supplemental Differentiated Curriculum'need to be applied, that is, to provide advanced contents for fast learners, and plain contents for slow learners. Level Based Differentiated Curriculum could be implemented by ability grouping either between classes or within classes. According to these two exemplary models, the implementation models for supplemental course and enriched course are determined. The contents for supplemental course are comprised of minimal essential elements selected from the standard course at a decreased level of complexity and abstraction. The contents of enriched courses are focused on various applications of mathematical knowledge in the real world. Special remedy course will be offered to extremely underachieved students, The principles of developing teaching-and-learning material for special remedy course were obtained from the histo-genetic principle, progressive mathematizing principle, and constructivism.

The main purpose of this study was to compare the clinical competency in different instructio nal methods for funda- mentals of nursing practicum, standardized patients methods story as text method ,and traditional lecture/model method. Method: The study was designed as a quasi-experimental, nonequivalent control group post-test design with three separate classes of sophomore students attending fundamentals of nursing classes at one baccaleureate nursing school located in metropoli tan Seoul area. Control group was taught by traditiona lecture/ model method and two experimental groups were taught by standardized patients method and story as text method. Data were collected from September, 1999 to June 2001. There were 36 students in the standardized patient method group, 38 students in story as text group, and 40 students in the control group. Data analysis was done using SPSS WINDOW 9.0. Result: The results showed that the standardized patients method and story as text method groups were significantly better in clinical judgement and communication skills than the traditional lecture/model method group. The standardized patients method group was significantly better in clinical nursing skills performance than two other groups. However, there was no significant difference among the three groups in student satisfaction. Conclusion: The standardized patients method is an effective in teaching clinical cometency for student nurses. It is necessary to explore more efficient way to develop standardized patients cases for wider areas of nursing education. Also, it is recommended to develop more research projects with many nursing programs.

경쟁기반의 무선 랜에서 채널의 이용률을 최대로 하는 것과 대역폭의 공평한 할당은 다루어야 할 중요한 주제이다. 그러나 위의 두 목적을 동시에 달성하는 것은 매우 어렵다. 이들 목적을 위하여 많은 연구들이 이루어져왔다. 본 논문에서는 IEEE 802.11e 무선 랜에서 여러 트래픽 클래스 간의 공평한 전송을 지원할 수 있는 제어 메커니즘을 제안한다. 제안된 알고리즘에서 각 클래스 트래픽들이 자신의 평균 long-term과 short-term 전송시간 값의 차이와 자신에게 할당된 전송 시간을 비교하여 $CW_{min}$값을 조절함으로써 공평성을 지원한다. 제안된 알고리즘은 공평성 지원을 위하여 다른 연구에서와 같이 각 트래픽 클래스들이 네트워크 내의 정확한 노드의 수에 대한 예측을 필요로 하지 않는다. 뿐만 아니라 AP(Access Point)나 모바일 호스트에 어떠한 수정도 필요하지 않는 장점을 가진다.
