Dynasty period, using Ji-Cho as the main ingredient. The official name of Jindo Hong-Ju is Traditional Red Liquor. Also, Hong-Ju which is red has a unique taste. The urpose of this study is to analyze the satisfaction and re-purchase intention of Jindo Hong-Ju. This paper investigates what determines the satisfaction and re-purchase intention of Jindo Hong-Ju for a consumer. There have been 300 samples and 250 returns. 212 of them are used for this study. The 212 samples are used to analyze the Jindo Hong-Ju. he main results are as follows. First, the multiple regression result shows that the consumer`s satisfaction for the Jindo Hong-Ju is affected by the ``Taste and Perfume``, ``Sales and distribution``, ``Price service``, and Hangover and health. Second, ``Advertisement and publicity` has no effect on satisfaction. Third, Jindo Hong-Ju`s satisfaction is positively affected by the re-purchase intention.

콘크리트 구조물이 대형화됨에 따라 설계단면이 증대되어 상대적으로 많은 경제적 손실을 부담하게 된다. 따라서 단면을 감소시키면서도 소요의 하중에 안전한 구조물을 건설하기 위해서는 우선적으로 구조물 건설에 기초가 되는 고품질, 고내구성의 고강도 콘크리트 개발이 절실히 요구된다 본 연구에서는 일정 시멘트비 및 혼화재 비율하에서 소요의 워커빌리티가 확보되는 고강도 콘크리트를 시간과 온도의 변화에 따라 증기 양생하여, 압축, 인장, 휨강도 뿐만 아니라 파괴특성을 실험적으로 연구하였다. 시료 제작시 시멘트 입자 사이의 공극 및 불연속 영역을 충전하여 고밀도화하기 위한 콘크리트용 혼화재로 시멘트 비표면적이 상당히 작은 초미립 분말인 실리카흄을 이용하였다. 또한 AE감수제 및 고성능 유동화제를 사용하여 혼화재의 첨가에 의하여 발생될 수 있는 워커빌리티의 감소를 방지하였다. 실험결과에 의하면 일정 양생 지속 시간하에서 온도의 증가에 따라 콘크리트의 압축, 인장 및 휨강도가 전반적으로 증가하였다. 동일하게 일정 온도하에서 양생 지속시간이 커짐에 따라 강도들이 증가됨을 알 수 있었다. 따라서 상대적으로 높은 온도와 긴 지속 양생 조건하에서 파괴에 대한 저항력이 크게 나타났다. The compressible, tensible, and flexibleresistance of the high strength concrete is analyzed by the experimentation in the present study. For the test, we cure several samples with the silica fume as a mixture being become dense the spaces between the particle of cement under the variation of both the temperature and the curing-interval. Then, the superplasticizer and the ezcon are also used to satisfy the required workability for construction. The compressible, tensible, and flexible resistances to a stress are increased as increasing the temperature and the time interval for the curing. Therefore it is concluded that the overal fractural and mechanical properties is improved by mixing the silica fume into the cement.

The purpose of this in vitro study was to evaluate contraction of the human gingival and periodontal ligament fibroblast in the collagen matrix. The cell cultures were prepared using human gingiva and tooth. The collagen gels were observed daily with an inverted microscope and their area was determined by measuring the diameters of the collagen gel. The configurations of human gingival and periodontal ligament fibroblasts were done by SEM observation. The results as follows; 1. The contraction was found to be proportional to seeding cell without seeding cells, the contraction was not occured. 2. Periodontal ligament fibroblast was shown more fast contraction than gingival fibroblast. 3. The collagen matrix was translucent initially, but with fully contraction, the structure become opaque. 4. The collagen matrix with fibroblast were aggregated to form bundles and reorganized collagen fiber.

洪春杓,吳濟植,金鎭彦 공주대학교 사범대학 과학교육연구소 1990 과학교육연구 Vol.22 No.1

Recently science curriculum in middle school was reformed the fifth and the science textbook of middle school is five species. In order to prompte educational effect, this study compared and analyzed five kinds of new science textbook with an old science textbook of the second year in middle school The results of this study can be summarized as follows. 1) Reformed five kinds of science textbook have various contents by participating 50 authors 2) Reformed science textbook increased 10 pages more than old science textbook of middle school in quantity. 3) It was found out that the numbers of the "Study and Observation" and "Exercises and Questions" in new science textbooks increased. 4) The numbers of Pictures were unchanged and the numbers of Tables. Experiments, Exercises and Composite Questions were decreased. 5) The 38∼42% was appeared the ratio of Experiments, Tables, Pictures, and Goethic type Terms in more than three kinds of science textbooks. 6) New science textbooks were reflected 61∼75% of an old science textbooks in Pictures, Goethic type Terms, Tables, and Experiments. As these results Terms and Contents reprented by Goethic type in science textbook should be selected carefully in order to prompte educational effect. The selection of Exercises, Composite Questions, Experiments and Observations should be allocated equally to each unit and behavior area. And this study suggests that there should be introduced experiments of an environment pollusion and its influence into a science textbook.

趙弘濟 울산대학교 1984 연구논문집 Vol.15 No.2

流域內 降雨一流出 水文응닫ㅂ은 斜面길이의 分布특성으로 나타내어진다. 流域의 地形特性은 洪水到達時間으로 표현되며, 洪水到達時間에 확률밀도함수를 적용시키면 降雨一流出응답함수인 순간단위도를 구성할 수 있다. 浸透地域의 流出率, 洪水到達時間 및 尖頭流量은 先行降雨量, 地形因子 등에 의해 결정되며, 응답함수에 의해 유도되는 직접유출수문곡선은 유효강우량의 산정方法에 따라 그 재현정도가 달라진다. 본 논문에서는 Horton의 침투능 eq.을 이용한 유효강우량 산정법에 의해서 유출기본방정식을 재구성하였고, 이 방정식에 의한 직접유출수문곡선의 재현성을 검토하였다. The hydrologic response function in watershed is expressed by the distribution function of slope length. The characteristic of topographical factors is represented to the concention time, and the instantaneous unit hydrograph is derived which is hydrologic response function by the application of probability density function. The method of calculation of effective rainfall should play important roles in the transformation process from hydrologic response function to hydrograph. In this paper, the Horton's infiltration equation is used as method of calculation of effective rainfall, a new response function of runoff process is derived and is tested by comparing the observed and estimated values.

조홍제,김정식 울산대학교 1999 공학연구논문집 Vol.30 No.1

지리정보시스템(Geographic Information System)을 이용하여 도시하천유역을 격자로 구성한 후 강우로 인한 지표면 흐름을 운동파해석으로 유출을 모의하였고 적용성을 검토하였다. 국립지리원에서 1:5000 수치지도로 제작된 유역면적 125.4km², 유로연장 23.4㎞인 사연제 유역을 대상지역으로 선정하였고 GIS Tool인 Arc/Info를 활용하여 본 유출모형에 필요한 지형인자를 추출하였다. 그리고 Arc/Info의 모듈인 GRID를 사용하여 수지지도를 100m100m 의 DEM (Digital Elevation Model)자료로 변환하였고 AML(Arc Macro Language)를 이용하여 강우-유출 모형을 구성하였다. 지표류에 대한 운동파의 해석은 특성곡선법을 이용하였으며, 본 모형의 적용성 검토를 위해 실측 유출곡선과 비교하였다. 그 결과 유출수문곡선의 형태는 실측치와 유사하였고, 첨두도달시간은 거의 일치하였으나 첨두유량은 재현성이 비교적 떨어지는 것으로 나타났다. 그리고 추적기간의 크기에 기인한 유출량의 변동성을 파악하기 위하여 추적기간을 600 (sec) 와 300 (sec)로 선정하여 관측된 두 호우사상에 대해 각각 적용한 결과 첨두도달시간은 거의 변화가 없었으며, 첨두유량은 각각 0.27%, 9.60%의 변화가 나타났다. This study is on the application and the verification of the rainfall-runoff model with distributed parameters of catchment. This model was constructed of cell-based and analyzed the surface flow by kinematic wave. The catchment for applying selected SAYUN DAM that was area of 125.4㎢ and main stream length of 23.4㎞. To construct the model, this study was using the digital elevation map(1:5,000) and landuse map(1:5,000) and a tool of GIS(Geographic Information System),Arc/Info and its interior language(AML), was used for the analysis of physiographic characteristics. This model was used method of characteristics for analysis of kinematic wave analysis. To verify the simulation, this study made a comparison between observed hydrograph and simulated one. As the simulated results showed that the shape of hydrograph was similar to the observed one, ut the peak flow relatively increased. And it verified the effects when the routing period changes as long period or short period. Routing period was selected mean equivalent time(600sec) and its half (300sec). The results that applied to two events was 0.27% and 9.60% in the peak flow and there was no changing the time of peak.

The purpose of this research is to compare and to analyze eight different science textbooks Ⅱ (the last volume) that are presently in use at the high school. The items that were compared and analrzed are as follows: The construction of each textbook in quantity. The construction of experimentation contents. The construction of contents in textbooks. This study will provide the basic data that is needed to effectively accomplish aims of science education and to enable a guidance teacher to reconstruct the textbook properly to the real condition exiting in each school. The findings of the research are as follows: 1. There is little difference in quantity of materials. But there is difference in quantity of each unit. 2. The number of Gothic-type terms used in each textbook is not unified. The sort of Gothic-type terms used in each textbook is also varied. 3. Photographs and pictures are presented in black and white. They are used for only explaining. 4. Material and method used in experimentation are showed in many ways. But some units are given too much importance. 5. Contents are consisted variously according to authors under the basic frame of education curriculum.
