일 종합병원 병동 간호단위의 간호효율성 평가-자료포락분석의 적용
이수연,임지영,Lee, Soo-Youn,Lim, Ji-Young 한국가정간호학회 2011 가정간호학회지 Vol.18 No.2
Purpose: The aim of this study was to evaluate the efficiency of nursing units in a hospital using DEA. Methods: Data were collected using the medical information system of a general hospital in a city. Input variables were number of nurses, number of nurse-aides, number of beds, and overhead costs. Output variables included number of admitted patients, rate of bed utilization, satisfaction of discharged patients, and prevention rate of safety accidents and sores. EMS Window version 3.1 was used to measure the efficiency score and descriptive statistics were applied to analyze the general characteristics of variables. Results: The average efficiency score of 18 general nursing units was approximately .99. Nine nursing units had a 1.00 efficiency score. Conclusion: Our findings reveal that nursing units operated very efficiently. To increase efficiency of inefficient nursing units, we recommend results of the DEA slack analysis as a benchmark of the most efficient nursing unit.

관행 고추밭과 유기농 고추밭에서 절지동물의 군집 구조와 생물다양성의 비교
이수연,김승태,임재성,정종국,이준호,Lee, Sue-Yeon,Kim, Seung-Tae,Im, Jae-Seong,Jung, Jong-Kook,Lee, Joon-Ho 한국유기농업학회 2013 韓國有機農業學會誌 Vol.21 No.4
본 연구는 관행포장과 유기포장에서 절지동물의 군집 구조와 생물다양성을 비교하기 위해 실시되었다. 조사기간 중 채집된 절지동물은 관행포장에서 6,901개체였으며 유기포장에서는 21,871개체로 총 28,718개체였으며 10목 24과 36종으로 동정되었으며 농법별 절지동물 군집을 구성하는 종수는 관행농과 유기농 모두 32종으로 같았고 관행포장에서는 파리목, 유기농에서는 벌목과 톡토기목의 종지수가 높았다. 대만총채벌레(F. intonsa)는 농법에 관계없이 발생밀도가 현저히 높았고 관행포장에서 우점종은 담배나방(H. assulta)이었고 유기포장에서는 줄무늬빗톡토기(H. mediaseta), 파리류 4(Diptera sp. 4) 및 별늑대거미(P. astrigera)였다. 절지동물 군집의 생물다양성은 지표면에서 종다양성이 관행포장에서 유기포장보다 높았으며 통계학적으로 차이가 있었다. 농법간 절지동물의 군집의 유사성은 지표면 및 지상부 식물체에서 활동하는 절지동물 군집은 대체로 농법에 의해 구분되었으며 그 유사도는 각각 34.07%와 26.95%로 비교적 낮아 농법간 이질성이 있었다. 생태학적 기능군의 종지수는 지상부 식물체에서 일반군, 해충군 및 천적군 중 기생포식자군에서 통계학적인 차이가 있었으며, 해충군과 기생포식자군 모두 유기포장에서 높았다. 발생밀도는 지표면에서 천적군 중 포식자군이 유기포장에서 관행포장에 비해 약 2배 정도 높았고 통계학적으로 차이가 있었다. 종다양성은 지상부 식물체에서 일반군과 천적군 중 기생포식자군에서 통계학적인 차이가 있었다. 개별 생태학적 기능군의 농법별 상대적 발생밀도 변동에서 관행포장에서는 해충군의 점유도가 높았고 유기농에서는 분해자군의 점유도가 현저히 높았다. 본 연구결과는 유기농업에서 효율적인 해충관리방안을 구축하는데 있어 유용한 절지동물 군집 정보를 제공할 것으로 사료된다. This study was conducted to compare the community structure and biodiversity of arthropods between conventional and organic red pepper fields. A total of 36 species of 24 families belonging to 10 orders from collected 28,718 arthropods; 6,901 individuals from conventional field and 21,871 individuals from organic field. A number of species comprising arthropod community was same in both fields as 32 species. Species richness of Diptera was the highest in conventional field and that of Hymenoptera and Colembolla was the highest in organic field. Abundance of Frankliniella intonsa was the highest regardless of farming method. Helicoverpa assulta was dominant in conventional field, and Homidia mediaseta, Diptera sp. 4 and Pardosa astrigera were dominant in organic field. Diversity of community on the ground was higher in organic field and statistically different. Similarity of arthropod community showed difference with 34.07% on the ground and 26.95% in the plant above ground. In the ecologically functional guild: species richness of general, pest and parasitoid of natural enemy groups in the plant above ground were statistically different and pest and parasitoid groups were higher in organic field, abundance of predator group of natural enemy on the ground was 2 times higher in organic field and statistically different and diversity of general and parasitoid groups in the plant above ground were statistically different. In the relative occupancy rate, pest group was the highest in conventional field and decomposer group was the highest in organic field. The results of present study is considered to provide useful information of arthropod community for developing efficient insect pest management in organic farming.

U(6/12) Dynamical Supersymmetry in 171,172Yb
이수연,J. H. Lee,노태익 한국물리학회 2008 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.53 No.2
The U(6/12) dynamical supersymmetry has been discussed within the framework of the inter-acting boson-fermion model, which describes collective states in odd-mass nuclei. In this work, theSU(3)limitofU(6/12)supersymmetryhasbeenconsideredtoexplainthecollectiveproperties of deformed nuclei, with the focus on identical bands in neighboring even-even and odd-A nuclei. The E2 transition rates between low-lying states and the electric quadrupole moments are given in closed form in the SU(3) limit of the U(6/12) symmetry. The present results are applied to the ground-state bands in 171,172Yb and are compared with experimental data.
