The amount of aids by Korea continues to grow, and it is essential to increase the effectiveness of Korea’s aid in line with the goals of international society. Therefore, the goal of this study is to develop a quantitative approach, by which aid effectiveness can be measured and increased, with application to the previous agricultural ODA projects of Korea International Cooperation Agency (KOICA). To this end, this study utilizes the Analytic Hierarchy Process that makes use of evaluation scores of experts from evaluation reports (meta-evaluation) and field visits. Among The five OECD DAC criteria, it is found that Effectiveness is the most important criterion, while in the analysis of priorities in agriculture, Agricultural Water Resources is found to be the most important area. By applying the same method to the subcategories, criteria by which to compare projects and to determine the order of priorities is established. This study also analyzes the attributes of agricultural ODA projects of KOICA by examining the factors that affect project performance, international studies on aid effectiveness, the OECD DAC Peer Reviews, CDI, and QuODA. Project size in budget and period are selected as internal factors. Policy, cultural environment, economic structure, and population distribution of the partner countries are selected as external factors. The key analytic result from using the aforementioned factors is that there is no significant relationship among project performance and internal factors. However, significant relationships among project performance and external factors are found, in line with partner countries’ characteristics. Furthermore, the key analytic results in terms of economic structure and population distribution are that the performance of the agricultural ODA projects of KOICA is positively related to the agricultural GDP of the partner countries, and that they show high-level performance in regions with a high proportion of rural residents. Based on these findings, the important of the agricultural sector in reducing poverty in the ODA projects in agriculture of KOICA is confirmed.

The purposes of this study are to make an operative treatment option of thoracolumbar burst fractures by the degree of initial kyphotic deformity or by the degree of initial loss of anterior vertebral height. We analyzed sixty-three cases of one segmental thoracolumbar bursting fractures treated surgically by posterior or posterolateral fusion with short segmental transpedicular screws fixation method using Diapason or CD from January, 1992 to October, 1996. Indications of operative treatment were that the degree of initial kyphotic deformity was above 15 or initial loss of anterior vertebral height was above 30%. Minimum follow-up period was 12 months and the results were as follows: 1. Entirely, mean kyphotic angle was 21.6 initially, 11.3 postoperatively and 14.2 at the end of follow-up. Mean anterior vertebral height was 59.6% initially, 83.8% postoperatively and 80.8% at the end of follow-up. So 10.3, 24.2% was corrected postoperatively and loss of correction was 2.9, 3% at the end of follow-up. 2. In the respect of the degree of initial kyphotic deformity, when compared above 30 with below 30, loss of correction was 7.3, 1.4 at the end of follow-up respectively and this result had significant difference between these two groups statistically. 3. In the respect of initial loss of anterior vertebral height, when compared above 55% with below 55%, loss of correction was 7.7%, 2.2% at the end of follow-up respectively and this result had significant difference between these two groups statistically. 4. In the respect of time interval from injury to operation, when compared within 2 weeks with after 2 weeks, respectively loss of correction was 1.7-2.2, 3-3.9% and 4.1, 6.7% at the end of follow-up and this results had significant difference between these two groups statistically. These data suggested if initial kyphotic angle is below 30 or initial loss of anterior vertebral height less than 55%, short segmental transpedicular screw fixation provide sufficient stability but if initial kyphotic angle is above 30 or initial loss of anterior vertebral height is above 55%, additional anterior interbody fusion may be considered.

We evaluated the use of ultrasonography and arthrography in 15 patients, 16 cases with congenital dislocation of the hip from January 1995 to December 1996. All patients in this study was managed with following management program. Ultrasound study was performed as soon as possible after admission and applied continuous skin traction in modified Bryant's method until +2 station was achieved according to Gage and Winter's traction station. When this had been accomplished, arthrogram was performed and reduction was attempted under general anesthesia. Mannual closed reduction was tried at first and if failed, open reduction was attempted. K-wire fixation or capsulorrhaphy was occasionally performed in the unstable hip after reduction was acomplished and then the hip was immobilized in a bilateral hip spica cast. Inverted limbus was found in all cases at both ultrasonography and arthrography. Reduction was achieved by closed reduction in 6 cases, closed reduction with percutaneous K-wire fixation in 4 cases, open reduction with K-wire fixation in 2 cases and open reduction & capsulorrhaphy with K-wire fixation in 2 cases. The effect of prereduction traction was not evaluated in our study, but ultrasound study performed as soon as possible after admission was effective method for detection of the hip abnormality & making a management plan and arthrogram performed under general anesthesia was effective method for making a reduction plan.
