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 as follows; linear planning method, simulation 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 $55.18{\tiems}10^6ton$ and $63.7{\times}10^6ton$ at 95% and 90% supply reliability respectively which are above the planning water supply amount of $50.0{\times}10^6$ton when the simulation method is introduced as the standard.

We have developed a small bore x-ray CT for small animal imaging with a linear x-ray detector array and small-scale slip rings. The linear x-ray detector array consists of 1024 elements of 400□m×400□m with a gadolinium oxysulfide (GOS) scintillator on top of them. To avoid use of expensive large diameter slip rings for projection data transmission from the X­ray detector to the image reconstruction system, we used the wireless LAN technology. The projection data are temporally stored in the data acquisition system residing on the rotating gantry during the scan and they are transmitted to the image reconstruction system after the scan. With the wireless LAN technology, we only needed to use small-scale slip rings to deliver the AC electric power to the X-ray generator and the power supply on the rotating gantry. The performances of the small animal CT system, such as SNR, contrast, and spatial resolution, have been evaluated through experiments using various phantoms. It has been experimentally found that the SNR is almost linearly proportional to the tube current and tube voltage, and the minimum resolvable contrast is less than 30 CT numbers at 40kVp/3.0㎃. The spatial resolution of the small animal CT system has been found to be about 0.9Ip/㎜. Postmortem images of a piglet is also presented.

The estimation of parameters in regression models with multiplicative errors is usually based on the gamma or log-normal likelihoods. Under reciprocal misspecification, we compare the small sample efficiencies of two sets of estimators via a Monte Carlo study. We further consider the case where the errors are a random sample from a Weibull distribution. We compute the asymptotic relative efficiency of quasi-likelihood estimators on the original scale to least squares estimators on the log-transformed scale and perform a Monte Carlo study to compare the small sample performances of quasi-likelihood and least squares estimators.

The planning stage of laser scanning is crucial for acquiring high-quality 3D source data. It involves assessing the target space's environment and formulating an effective measurement strategy. However, existing practices often overlook on-site conditions, with decisions on scanner deployment and scanning locations relying heavily on the operators' experience. This approach has resulted in frequent modifications to scanning locations and diminished 3D data quality. Previous research has explored the selection of optimal scanner locations and conducted preliminary reviews through simulation, but these methods have significant drawbacks. They fail to consider scanner inaccuracies, do not support the use of multiple scanners, rely on less accurate 2D drawings, and require specialized knowledge in 3D modeling and programming. This study introduces an optimization technique for laser scanning planning using 3D simulation to address these issues. By evaluating the accuracy of scan data from various laser scanners and their positioning for scanning a retaining wall structure in a small-scale building, this method aids in refining the laser scanning plan. It enhances the decision-making process for end-users by ensuring data quality and reducing the need for plan adjustments during the planning phase.

Recently, various geographic information systems have been used based on spatial information of geographic information systems. Accordingly, it is essential to produce a large-scale map as a small-scale map for various uses of spatial information. However, maps currently being produced have inconsistencies between data due to production timing and limitations in expression, and productivity efficiency is greatly reduced due to errors in products or overlapping processes. In order to improve this, various efforts are being made, such as publishing research and reports for automating domestic mapping, but because there is no specific result, it relies on editors to make maps. This is mainly done by hand, so the time required for mapping is excessive, and quality control for each producer is different. In order to solve these problems, technology that can be automatically produced through computer programs is needed. Research has been conducted to apply the rule base to geometric generalization. The algorithm tolerance setting applied to rule-based modeling is a factor that greatly affects the result, and the level of the result changes accordingly. In this paper, we tried to study the effectiveness of mapping according to tolerance setting. To this end, the utility was verified by comparing it with a manually produced map. In addition, the original data and reduction rate were analyzed by applying generalization algorithms and tolerance values. Although there are some differences by region, it was confirmed that the complexity decreased on average. Through this, it is expected to contribute to the use of spatial information-based services by improving tolerances suitable for small-scale mapping regulations in order to secure spatial information data that guarantees consistency and accuracy.

The occupational health problems are the major issue in the modern industrial society. Especially the small scale industries have many hazardous factors and not any occupational health programs in itself. Fortunately. the government-funded subsidiary program was developed and carried out in the past six years in our country. The purposes of this study were to find out the actual condition of the occupational health personnel's accomplishments for the government-funded subsidiary program for small scale industries and to provide basic data for setting up more developed subsidiary occupational health program. Data were collected through 6 kinds of service records review. These service records were written by 3 occupational health personnels were attached to the one subject center of KIHA. were undertaken during March to December, 1997. at 95 small scale industries which were applied the government-funded subsidiary occupational health program. Results were as follows 1. Concerning 95 small scale industries showed characteristics of a typical small scale industry. 2. A doctor visited in industries total 190 times per year, average 19 industries per month, twice per year and industry. A hygienist visited in industries total 378 times per year, average 38 industries per month, four times per year and industry. A nurse visited in industries total 477 times per year. average 47 industries per month, 5 times per year and industry. 3. 3 occupational health personnels accomplished total 3,869 items. A doctor accomplished total 539 items per year, each time 3 items In an industry. A hygienist accomplished total 1.581 items per year, each time 4 items in an industry. A nurse accomplished total 1.749 items per year, each time 4 items in an industry. 4. The major contents of doctor's accomplishment were 'health consultation for suspicious worker with general & occupational disease', 'a check of the workplace & special health education', 'guidance of special medical examination in the second half of year', etc. The major contents of hygienist's accomplishment were 'pretest & guidance of planning for evaluation of working environment'. 'evaluation for ventilating facilities & suporting self inspection', 'guidance of MSDS recording & chemicals management', etc. The major contents of nurse's accamplishment were 'health counseling of general & special medical examination results'. 'health education of preventing occupational disease & health disorder'. 'guidance of subsidiary program planning', 'selecting & guidance of health monitor', etc. It was concluded that the occupaional health personnels implemented the subsidiary program according to the order of health management guide. The current health management guide of subsidiary occupational health program in which the fixed contents, visiting number & periods is not desirable. That guide is left the characteristics of small scale industries out of consideration. It is suggested that occupational health management guide should be developed according to the general & environmental characteristics of each small scale industry, and on the other hand, the more specific guide for each occupational health personnel should be developed.
