A carcinoid tumor of the stomach is uncommon, has no clinical symptoms, and is regarded as a benign. It is also incidentally found in most cases. 48-year-old woman with gastric carcinoid tumor was admitted. She had suffered from a anorexia and a dry mouth for 4-months. A gastroscopy revealed a polypoid mass on the greater curvature of the mid-body of the stomach which was subsequently thought to be an adenocarcinoma. An endoscopic mucosectomy revealed however, that it was a carcinoid tumor. A case of carcinoid tumor of the stomach is here by presented with a brief literature review.

Ordinarily stow net fisheries was used by floater beam and sinker beam for the purpose of spreading the mouth of net. But it was not only iuconvenient and dangerous but much defective. In this thesis, we have studied fundermental experiment of the improved stow net fishing gear using head rope, ground rope and otter sail instead of floater beam and sinker beam. From the result of this experiment, it has been succeeded for fishing work to achieve basically without any difficulty. The results obtained in this study were as follows. 1) The resistance of fishing gear was estimated R≒7V2 as possible as it is taken greatly. (R: Resistance V: the rate of current) 2) The interval of otter sail was spreaded smoothly. Being in normal condition, it was maintamed the width 37-38m. It was heared comparison with net mouth of ordinary gear, and the shearing force was enough. 3) The height of mouth was lower than we have anticipated to and seemed to have the supplement of buoyancy. But according to increasing the rate of current, the lowness of mouth height was little affected. 4) The height of otter sail was decreased at the rate of 30% by the rate of current, on the contrary, the height of wing was not decreased owing to sufficient buoyancy, 5) The adjustment of extention length of hanging wire(connected with fishing boat) and raising wire(with otter sail) was great important problem and it must be dealed with the most moderatly because of a corelation between the spreading of fishing gear and catching ability. 6) On the depth of 30m, it was taken 25 minuits to cast anchor and lines, 20 min cast net, 24 min haul net, 45 min haul lines and heave anchor, respectively. 7) The improved stow net with otter sail was cleared up the defects and difficult problems in ordinary gear using floater beam and sinker beam, and it have more advantages of fishing work than ordinary one. But there were involved in lots of problems in details to solve in the future.

The major purpose of this study was to develop enhanced hydrometheorological factor regression with Box-Jenkins model. The metheorological factor regression model is a regression model of methorological factors which are belived to be the most effective components in rainfall phenomena under the assumption of their accurate prediction. These parameters are determined from the occurrence characteristics of stoms by using the past metheorological data series, and AR(1), AR(2), ARMA(1, 1) and ARMA(2, 1) models are used on the basis of Box-Jenkins time series as the prediction model of metheorological factors. The regression analysis between metheorological factors and rainfall is carried out for two types of storms, frontal type storms and typoon/low atmospheric pressure type storms to calibrate parameters in the metheorological factor regression model. The results of calibration show that the most effective components in rainfall phenomena among metheorological factors are 24hr-variation of atmospheric pressure, daily mean temperature, daily mean sea atmospheric pressure and cloud amount by which metheorological factor regression models are determined in the region. The prediction models of these factros are also determined as ARMA(2, 1) model from the calibration.

金成原,李曾錫 慶一大學校 1997 論文集 Vol.14 No.2
In this study, it is applied for HEC-6 model which is 1-dimensional bed profile change calculation model to analyze bed profile change at the upstream and downstream of submerged weir in the natural channel. As the result of this study, it is analyzed that root-mean-square error and volume error is 1.08m and 2.48% between calculation and observation of bed profile change in 1996 year. Furthermore, it is adjusted for HEC-6 model to simulate long-term bed profile change by the 2016 year. As the result of this analysis, it happens 1.0∼2.0m aggradation in the upstream of submerged wier and 0.5∼1.5m Degradation in the downstream of submerged weir. But by the removal of air in the submerged weir top, it can transport the sediment downstream. therefore, it will sustain stable bed in the future. And it will be occurred local scouring by constant aggregate gathering more than expected bed profile change, it is considerable decision for the large sacle aggregate gathering in this study channel

The purpose of the study was to construct a forecast system of flood inundation area at natural stream channels. The study built the system to interpret the flood inundation area in four stages ; constructing topography data around the stream channel, interpreting flood discharge, interpreting flood elevation in the stream channel, and interpreting the flood inundation and mapping. According to the result of the analysis, as for the characteristic of flood inundation around the area within the purview of this study, although there were areas where flood inundation over a bank caused a flooded area, the failure of the internal drainage in the ground lower than flood elevation caused more serious problems. Rather than the existing method where only the estimated flood elevation data is used based on the hydrographical stream channel trace model(such as the HEC-RAS model) to establish the flood inundation area, if the procedure introduced in this study was applied to interpret the floodplain, actual flood inundation area could be visibly confirmed.

The subject basin of the research was the basin of Yeongcheon Dam located in the upper reaches of the Kumho River. The parameters of the model were derived from the results of abstracting topological properties out of rainfall-runoff observation data about heavy rains and Digital Elevation Modeling(DEM) materials. This research aimed at suggesting the applicability of the CELLMOD Model. a distribution-type model, in interpreting runoff based on the topological properties of a river basin, by carrying out runoff interpretation for heavy rains using the model. To examine the applicability of the model, the calculated peaking characteristics in the hydrograph was analyzed in comparison with observed values and interpretation results by the Clark Model. According to the result of analysis using the CELLMOD Model proposed in the present research for interpreting the rainfall-runoff process, the model reduced the physical uncertainty in the rainfall-runoff process, and consequently, generated improved results in forecasting river runoff. Therefore it was concluded that the algorithm is appropriate for interpreting rainfall-runoff in river basins. However, to enhance accuracy in interpreting rainfall-runoff. it is necessary to supplement heavy rain patterns in subject basins and to subdivide a basin into minor basins for analysis. In addition, it is necessary to apply the model to basins that have sufficient observation data, and to identify the correlation between model parameters and the basin characteristics(channel characteristics).

This study aims at the effective estimation of water supply capacity of small scale reservoir and the proposal of the data which is necessary to establish the water resources management plan of down stream area of the reservoir in the future by comparison and examination about reservoir operation technique for the security of agricultural water in small scale reservoir. The result of flow calculation by Tank model is used for the input data as the inflow data which is needed for the analysis of water supply capacity. Stochastic method, simulation method, and optimization method are used to examine the water supply capacity, and water security amount is compared with each method. From the analyses of water supply capacities by each method, slightly different results are shown in spite of the effort to compare them equally using input data such as inflow data under equal conditions, and the comparison of water supply capacities by each method are follows; linear planning method, and transition probability matrix method in the order of amount from the largest. It is thought that the simulation method in which comparatively reasonable application of the inflow data is possible and is simulated in successive time series dam operation of the three methods used in this study thus, simulation model is proper to estimate the water supply capacity of agricultural small scale reservoir. And it is judged that the heightening of efficiency of water resources utilization according to the development of downstream area of dam may be possible using the upward readjusted water supply amount of 55.18×10^6ton at 95% and 90% supply reliability respectively which are above the planning water supply amount of 50.0×10^6ton when the simulation method is introduced as the standard.
