Estmating the quantity of outflow of short-time rainfall, which is troublesome problem, in urban Sewerage Planning, there are various of Rainfall-Intensity Formula. Among them three types such as I=a/(t+b), I=a/tⁿ, I=a/(√t+b) are widely used. Where t denotes rainfall duration in minutes, and the constants a, b and n are generally determined by either of the following tqo method: 1) Based on long-term observation values, Probability is calculated for each mintues(10,20,60,…80,120 min.)rainfall intensity is derived for the same return period, and finally the values for these constants are determined by mean of least square fitting.(Exact calculation method). 2) On the premise that "All the Rainfall-Intesity curve can be expressed multiplying the coefficient which represents inclination of the curve by Rainfall-Intesity of an hour." Dr. Isiguro expressed the Rainfall-Intensity for N-year probability in the form I_T=K_T. r_t where r_T and K_T denotes 1-hour rainfall and specific coefficient for N-year probability, respectively, and the latter can be determined by 10 and 60 minutes rainfall only.(Speific coefficient method). In this paper, though comparative study on the fitness of Exact calculation method and specific coefficient method in Sewerage planning of Gwang ju area, I have got following conclusions. 1. Exact calculation method applies better for return period T=20,30,50 years than specific coefficient method. 2. Specific coefficient method applies brtter for return period T=3,5,10 years than Exact calculation method. 3. There are little difference in suitability those of two methods for t ganging from 10 to 60 mintues and from 10 to 120 mintues. 4. Therefore, Specific coefficient method is more suitable partly in accordance with return period.

Fracture of cusp, on posterior teeth, especially those carious or restored, is major cause of tooth loss. Inappropriate treatments, such as unnecessarily wide cavity preparations, increase the potential of further trauma and possible fracture of the remaining tooth structures. Fracture potential may be directly related to the stresses exerted upon the tooth during masticatory function. The purpose of this study is to evaluate the fracture resistance of tooth, restored with composite resin inlay. In this study, MOD inlay cavity prepared on maxillary first premolar and restored with composite resin inlay. Three dimensional finite element models with eight nodes isoparametric solid element, developed by serial grinding-photographing technique. These models have various occlusal isthmus and depth of cavity, 1/2, 1/3 and 1/4 of isthmus width and 0.7, 0.85 and 1.0 of depth of cavity. The magnitude of load was 474 N and 172 N as presented to maximal biting force and normal chewing force. These loads applied onto ridges of buccal and lingual cusp. These models analyzed with three dimensional finite element method. The results of this study were as follows : 1. There is no difference of displacement between width of occlusal isthmus and depth of cavity. 2. The stress concentrated at bucco-mesial comer, bucco-disal comer, pulpal line angle and the interface area between internal slopes of cusp and resin inlay. 3. The vector of stress direct to buccal and lingual side from center of cavity, to tooth surface going on to enamel. The magnitude of vector increase from occlusal surface to cervix. 4. The crack of tooth start interface area, between internal slop of buccal cusp and resin inlay. It progresses through buccopulpal line angle to cervix at buccomesial and buccodistal comer. 5. The influence with depth of cavity to fracture of tooth was more than width of isthmus. 6. It would be favorable to make the isthmus width narrower than a third of the intercuspal distance and depth of cavity is below 1 : 0.7.

地域別 最適 確率降雨强度武의 誘導

金哲淳,林煥大,金雲中 조선대학교 국토개발연구소 1989 국토개발연구 Vol.9 No.1

This study places emphasis on invastigation each average rainfall record of the period of twenty years on the main districts(Kwangju, Mokpo, Yeosu) of Kwanju and Chunnam, and extracting the actually mesured amount of consistent rainfall per minute(10, 20, 30, 40, 60, 80, 100, 120, 180, 240, 300, 360, and 720 minutes). In order to study this paper, the caculation of probability rainfall amount selected four method(Formality distribation, Logarithm formality distribtuion, moment and Gumbel-chow method), and four appropriate types(Talbot, Sherman, Japanese and Semi-log types) for a Korean rainfall characteristic among various types are selected, the induction of optimal rainfall intensity formula is computerised, and laber saving and thechnical improvement is designed. The are as follows. 1. Semi-log type is suited to Kwangju district, and an average fit extent appeared to be 92.6%. 2. Japanese type is suited to Mokpo and Yeosu districts, and an average fit extent appeared to be 95.9% and 95.2%. 3. The average fit of this study's formulas appeared more high than the existing formulas.

This study has for that object to make the most economical and reasonable plans for drainage by deciding which one is higher in suitability among the specific coefficient method which is simple in calculation and is high in application, data collected for a long period of time and the probability rainfall intensity based on the exact method which is complicated in calculation. Therefore, we decided the suitability in the Cheju districts by investigation comparing value calculated through the specific coefficient method with value calculated through the exact method. As a result, the suitability in the Cheju districts turned out to be high in the specific coefficient method in general.

제주지방(濟州地方)의 확률강우강도식(確率降雨强度式) 유도(誘導)

강우현상은 지역별로 그 특성이 다르고, 장기간을 관측하여 보면 강우특성도 전에 비해서 많이 변화하므로 보다 정확한 배수계획의 수립이나 수공구조물계획을 위해서는 그 지역의 최근의 관측자료까지 포함한 강우특성을 연구하여 적용하는 것이 바람직하다. 따라서 제주지방의 주요 우량관측소(제주시, 서귀포, 성산포)의 최근 20년간(年間)의 자기우량기록지에서 연최대(年最大) 강우량만을 골라서 우량지속기간별로 실측우량을 발췌하였으며, 강우강도식은 일반적으로 많이 사용하고 있는 Talbot형(型), Sherman형(型), Japanese형(型)에다 새로운 Semi-log형(型)을 추가해서 제주지방의 지역별 최적확률 강우강도식을 유도해 본 결과 제주시는 확률년이 3년(年)~5년(年)에는 Japanese형(型), 그 외는 Talbot형(型)이고, 서귀포는 Sherman형(型), 성산포는 Talbot형(型)으로 나타났다. It is desirable to utilize the result after studying the rainfall characteristics including the latest observation data in the districts for the sake of establishment of the more accurate plans for drainage or plans for hydraulic stuctures because the rainfall phenomena are different in their characteristics by regional groups and if we make a meteorological observation for a long period of time, the rainfall characteristics also change a great deal as compared with the preceding years. Therefore, we selected only the annual maximum rainfall from the self-recording rain gauge of the main rainfall observation station (Cheju, Sogwipo, Songsanpo) in the Cheju districts in the last twenty years, extracted the rainfall by actual measurement by the rainfall duration, and induced the optimal probable rainfall-intensity formulas by regional groups in the Cheju districts, taking advantage of the rainfall formulas being in wide use in general, that is, Talbot type, Sherman type, Japanese type, and new Semi-log type. As the result, the return periods at Cheju station appeared to be three years to five years and the optimal probable rainfall-intensity formula at Cheju station, Japanese type and outside the city, Talbot type; Sogwipo, Sherman type; Songsanpo, Talbot type respectively.
