In this research, centrifuge model experiments and numerical approach of finite element method to analyze experimental results were performed to investigate the behavior of improved ground with sand compaction piles. One of typical clay minerals, kaolinite powder, were prepared for soft ground in model tests. Jumunjin standard sand was used to sand compaction pile installed in the soft soil. In order to investigate the characteristics of mechanical behavior of sand compaction piles with low replacement ratios, centrifuge model experiments with the replacement ratio of 40%, changing the width of improved area with respect to testing results the width of surcharge loads, were carried out to obtain of bearing capacity, characteristics of load-settlement, vertical stresses acting on the sand pile and the soft soil failure mechanism in improved ground.

Radiolographic findings of thirty eight cases of renal tuberculosis treated at this hospital during last 4 years were analysed with following results. The cases examined were 24 male and 14 female patients. Age distribution was broad and evenly distributed ranging form 2nd decases to 5th decades. Main symtoms complained were urinary frequency , hematuria, dysuria and flank pain. Findings of physical examinatin revealed tenderness of costovertevral angle, palpable mass on flank area and epidydimal indutration. The simple chest films showed pulmonary tuberculosis in 22 cases including 6 cases of active military type. Thirty one cases showed increased ESR, 8 cases showed AFB positive inurine and 12 cases showed bilateral renal tuberculosis. Through urographic findings nonvisualization, cyceopelviectasis, motheaten appearance of minor calyx, contracted bladder, delayed visualization, ureteral st icture and beading were observed in order of frequency. Five cases with miliary tuberculosis showed advanced renal lesion on urogram.

The purpose of this study was to develop an optimum equipment model considering various objective functions and variables of agricultural reservoir. Traditional optimum function for feasibility assessment is based on economic benefit, but we tried new approach of feasibility assessment based on the number of beneficiary. The data of Yuraimi reservoir and Yongbong reservoir in Yesan-gun such as numbers of related people, construction costs, safe diagnosis have been gathered for applying developed model. Data are used for determining optimum strategy with restricted cost. For verifying results of optimum maintenance, real maintenance data of Yuraimi reservoir were compared with simulated strategy. Results show that simulated maintenance strategies are 3 times more effective than real maintenance data.

The purpose of this study is to serve with some implications the development of the relations between teacher unions and educational authorities by finding out some factors which are thought to affect teachers' commitment to the Korean Teacher Union, by analyzing relative influence of the factors, and then by determining why teachers join the Union and why they join its activities. The results of the study are as follows: First, it was found that teachers' commitment to union shows great difference according to their genders, teaching career, school grades, types of school foundation, positions in union, and joining time. That is, male teachers have higher commitment than female; high school teachers have the highest commitment, while elementary teachers have the lowest; private school teachers have higher commitment that public school teachers; members who joined before the legalization of their union have higher commitment than those who joined after. Teachers' career didn't any significant difference. Therefore, it is thought that teachers' background variables should be considered in the labor-management decision-making processes. Second, it was indicated that the factor which exerts the highest influence on teachers' commitment to their union is the attitudes of the Ministry and Offices of Education and the next is their labor union satisfaction. So it is thought that it is critical for the educational authorities to have more democratic and flexible attitudes for the betterment of their relations with teachers' union. On the other hand, senior officials of union are supposed to make more sincere efforts to hear their members opinions and expectation in order to boost their organizational commitment. Colleagues' attitudes towards their union appeared as one major factor, which may be thought that teachers' social experiences with their colleagues may influence their commitment to union activities.

We developed an electromechanical gait trainer for rehabilitation of the persons with disabilities, which was designed to simulate normal gait with partial body weight support. The purpose of this study was to apply it to stroke patients and to evaluate its usability. Four nonambulatory stroke patients had 20 sessions of gait training with newly developed gait trainer for 5 to 6 weeks. Knee and ankle joint angles were measured by electrogoniometer during training. Main outcome was assessed by functional ambu- lation category (level 0~5). Knee and ankle joint angles during exercise in the gait trainer showed repetitive pattern of gait-like movement similar to normal gait, though it was variable among the subjects. Functional ambulation category levels after training were 2 in 3 patients and 1 in 1 patient. The electromechanical gait trainer was a useful device for gait retraining in stroke patients with severe neurologic impairments.

Objective: Comprehensive poststroke rehabilitation includes continuum of care after discharge from hospital. Day hospital is a milieu-oriented outpatient rehabilitation program that offers continuous rehabilitation service to promote psychosocial adaptation and quality of life. This study is to evaluate long-term effects of day hospital program in stroke patients. Method: Forty-eight stroke patients who received day hospital program for 2 or more months after inpatient rehabilitation program and 42 control stroke patients, who received only inpatient rehabilitation program, responded telephone interview for the study. Outcome measurement included the Korean Activities of Daily Living (K-ADL), the Korean Instrumental Activities of Daily Living (K-IADL) and the Medical Outcome Study 8-item Short Form Survey (SF-8). Results: There was no difference in many item scores of K-ADL between day hospital group and control group, but the item scores of dressing, washing face and hands were significantly higher in control group. Among the item scores of K-IADL, except managing money, most item scores of K-IADL were no significant difference between day hospital group and control group. All item scores of SF-8 were significantly higher in day hospital group than control group. Conclusion: Day hospital is an effective rehabilitation program to enhance health-related quality of life for stroke patients.
