본 연구에서는 점토층의 자중압밀을 시행하여 현장강도를 구현하기 위하여 1/70로 축소 모델링하여 원심모형실험을 수행하였으며, 점토구간에 PBD 타설시의 연약지반의 압밀침하거동을 분석하기 위하여서는 1/100로 축소모델링하여 원심모형실험과 전산해석을 실시하였다. 전산해석결과 성토체중심아래의 점토지반의 침하량은 1단계 성토제방하중 하에서 4.8개월 경과 후 최대 침하량은 41.1cm, 2단계 성토하중에서 4.2개월 경과 후의 최대침하량은 78.8, 3단계 성토하중에서 6개월 경과후의 침하량은 93.5cm의 침하가 발생하는 것으로 나타나 수치해석 결과와 원심모형실험결과 값의 유사한 경향을 확인하였다.

Background : Medical records thought to be reflecting the quality of medicine. By this ground, examination of medical records can be served to evaluate, and to improve the quality of medical care. To examine the medical records, we need some standards or checklists which can be used to sort out the problems. Methods: We developed checklists for medical records evaluation. We studied 1,677 medical records about its completeness using this checklists in one educational hospital. Survey was completed by 5 well trained staffs of medical record department. Results are analyzed. SPSS/PC+ program was used for statistics. Results : 13.8% of discharge summary was incomplete. Recording of the demographic information was also poor in incomplete medical records compared to complete ones. Progress note was recorded average 4.16 times during 11.9 hospital days. After 4th hospital day, recording rate of progress note dropped sharply. Rate of professor's signature on operation records was poor(27%). He or she who described the discharge summary well also wrote progress note well. Conclusions: Fill-up of demographic date should be stressed during medical record education program. Strategy to create the environment emphasizing the responsibility of professor on quality medical record should be made. We suggest new index (number of records/hospital stay) for the evaluation of completeness of progress note.

The set-net fishing is involved in the trap fishing method that intercepts the fishes migrating along the coast and induces them to be in the bag net stretched in advance. And this fishing also corresponds to the licensed fishing in fisheries law. Though its annual total production of around 50,000 to 70,000 M/T is less than in other fishery section, its price becomes higher because the fishes are sold in the live fish condition. Until recently, the set-net fishing is one of the preferred fisheries on account of its less operation expense and stably operating condition in a long term. In the meantime, the industrialization in Korea having been prospered along coastal area and the over fishing in terms of the powered and larger size fishing boat make the fishing ground environment worse yearly. In addition, its difficulty becomes more worse with issuing fishery product free import in July 1997; accordingly, the strategy for the set-net fishing through business rationalization should be considered. From the discussion of the sort of set-net, general present situation and operating actual state of set-net fishing, the improved methods for business rationalization in the present paper is proposed as follows: 1. to increase the fisheries resource through prevention of the marine contamination and purification of coastal area environment. 2. to save the labour cost through the improved the fishing gear. 3. to improve the fish quality through development of the process technology. 4. to increase the income of fishers through improvement of the distribution channels.
