본 연구에서는 자료포락분석 모형 및 멜퀴스트 생산성지수 분석방법과 2003년-2006년, 4년간 18개 국립공원의 자료를 이용하여 우리나라 국립공원의 효율성과 생산성에 대해 동태적 분석을 시도하였다. 효율성분석은 기술, 비용, 분배, 순수기술 및 규모의 효율성 등 다양한 효율성 구성요소를 측정하였으며, 생산성분석은 기술효율성 변화요소 (순수기술변화요소와 규모의 효율성변화) 및 기술변화요소로 분해하여 측정하였다. 측정결과 효율성 측정치의 연도별 차이는 나타나지 않았으나, 생산성측면에서 기술효율성변화, 기술변화, 생산성지수 면에서 연도별 차이가 나타났다. 국립공원을 산악형과 해양형의 두 유형으로 분류해 측정해 본 결과, 효율성 측면에서는 비용 및 분배 그리고 규모의 효율성에서, 생산성 변화 측면에서는 기술효율성변화, 기술변화, 생산성지수 면에서 커다란 차이가 발견되었고 산악형이 해양형에 비해 효율성과 생산성면에서 크게 우월하였다. The purpose of this paper is to analyze the dynamic efficiency and productivity change of 18 national parks in Korea using Data Envelopment Analysis (DEA) model and Malmquist productivity index (MPI) model using 4 years of panel data over the period 2003 through 2006. We use DEA model to measure cost, technical, allocation, pure technical and scale efficiencies. Furthermore, we use MPI model to measure efficiency (pure technical and scale) and frontier (technology) changes. We identify several important facts which seem to have strong relationship with various inefficiency estimates. First, we perform efficiency analysis to figure out what causes inefficiency and to provide the relative efficiency ranks, and to provide desirable guideline values for the efficiency score at which each inefficient national parks become efficient. Second, we couldn’t find any indication of efficiency differences but find indication of productivity differences among national parks. Third, we classify national parks into two groups, forest and ocean group, based on characteristics of parks, and conduct DEA and MPI analysis to see if there are some differences bet ween two groups. Two groups showed strong differences in cost, allocation and scale efficiencies and in MPI, frontier and technical efficiency changes.
Expression of Protein Kinase C on Allergic Nasal Mucosa
송영호,홍남표,조중생,최희석,안회영 대한비과학회 1998 Journal of rhinology Vol.5 No.1
Protein Kinase C (PKC) relays information in the form of a various extracellar signals across the membrane and is known toplay an important role in the production of B lymphocytes and T lymphocytes, in the antigen-presentation of Langerhans cell,and in inflammatory reactions. The presentation of allergens to T lymphocytes is likely an important aspect in the pathophysiologicalmechanism of allergic rhinitis. Although several theories have been formulated in allergic rhinitis, signal transduction ofthis disease remains unknown. In this study, we focused on the role of the enzyme PKC in the allergic mucosa of the nose. Specifically, we investigated the role and the distribution of PKC isozymes in the mucous membrane of the nose. We obtainednasal mucous membrane specimens from 10 patients with house dust mite allergy and 10 patients with normal nasal mucousmembrane. We performed an immunohistochemical study, an RT-PCR, and a densitometric measurement. PKCα, PKCβ, andPKCζ proteins were detected in the subepithelial layer of the allergic mucosa. However there were no detectable reactions inthe nonallergic mucosa. In the RT-PCR for PKCα, PKCβ, and PKCζ, there was no difference between the allergic and nonallergicnasal mucous membrane in terms of m-RNA expression. It is possible that the signal transduction pathway of PKC andover-expression of PKC protein at the post-transcription level contribute to the development of allergic inflammation in allergicnasal mucosa.

The objectives of this study are 1)to evaluate PMIS with quality of connections and services among construction processes ,design modeling (eg: architectural, structural, mechanical, and electronic modeling), and documents (eg: specifications, contract document etc), 2)to develop prototype of repository system, for managing interrelations about improved PMIS processes, output of process with evaluations and improvements, These improvements enable 1)construction planning with valid and latest informations, about method of construction, estimation, schedule planning information, budget planning through existing knowledge at the phase of design, 2)and providing to the point, informations and knowledges of each execution processes (such as construction planning/architectural structures/facilities/electrical systems at the phase of execution).
