2009년 8월 13일과 15일, 부산 해운대 해수욕장 앞 해상에서 이안류가 발생하였다. 또한, 올 여름인 2010년 7월 29일과 30일에도 이안류가 발생하여 피서객 들이 조난된 사고가 발생하였다. 해수욕객들은 전원 구조되어 인명 피해는 발생하지 않았지만 최근 이안류 발생이 너무 잦아져 이에 대한 원인파악과 대책마련이 시급한 실정이다. 본 논문에서는 파랑모형과 조류가 결합된 해빈류 모형을 기본으로 튜브거동까지 재현되는 사용자 편의를 위하여 GUI로 개발된 HAECUM 모형(HAEundae CUrrent Model)을 이용, 해운대 해수욕장의 이안류 발생 수치모의를 실시하였다. At Haeundae Beach in Busan, people were swept away by the fast-moving rip current and rescued, on August 13th and 15th, 2009 & July 29th and 30th, 2010. In predicting the wave-induced current and consequent tube movement for public safety, the coastal flows and waves are calculated at each time step and grid point by means of systematic interfacing of hydrodynamic and wave models (Lee, 2001). To provide a user-friendly simulation tool for end-users, the forecasting system has been built in a software package called HAECUM. Outputs from the system are viewed as graphs of tube positions with combined current vectors for easy decision of emergency management officials. The tube-wave interaction is taken into account and the traces of swim tube are simulated by using a Lagrangian random walk (Chorin, 1978; Lee, 1994). In this study, we use the Lee's approach (Lee, 1993) in estimating the surface onshore currents due to wave breaking.

Security of Upland Irrigation Water through the Effective Storage Management of Irrigation Dams

이주용,김선주,김필식,Lee Joo-Yong,Kim Sun-Joo,Kim Phil-Shik The Korean Society of Agricultural Engineers 2006 한국농공학회논문집 Vol.48 No.2

In Korea, upland irrigation generally depends on the ground water or natural rainfall since irrigation water supplied from dams is mainly used for paddy irrigation, and only limited amount of irrigation water is supplied to the upland area. For the stable security of upland irrigation water, storage level of irrigation dams was simulated by the periods. A year was divided into 4 periods considering the irrigation characteristics. Through the periodical management of storage level, water utilization efficiency in irrigation dams could be enhanced and it makes available to secure extra available water from existing dams without new development of water resources. Two study areas, Seongju and Donghwa dam, were selected for this study. Runoff from the watersheds was simulated by the modified tank model and the irrigation water to upland crops was calculated by the Penman-Monteith method. The analyzed results showed that relatively sufficient extra available water could be secured for the main upland crops in Seongju area. In case of Donghwa area, water supply to non-irrigated upland was possible in normal years but extra water was necessary in drought years such as 1998 and 2001.

Sarmanov형 이변량 일반화이항모형의 적합

이주용,김기영,Lee, Joo-Yong,Kim, Kee-Young 한국통계학회 2009 응용통계연구 Vol.22 No.2

급내/급간상관이 동시에 존재하는 이변량 이항자료에 대한 모형으로 Danaher과 Hardie (2005)는 베타이항분포를 제안한바 있다. 그러나 이 모형은 베타분포에 따르는 성공확률을 통해 급내 상관을 묘사하므로 그 적용범위가 양의 급내상관을 가지는 자료에 제한된다. 이 연구에서는 보다 더 넓은 범위의 급내 상관에 대해 유용성을 가지는 일반화가법/승법이항모형과 확장베타이항모형 등에 Sarmanov형식의 이변량 확장을 고려하고 이들을 기존 모형과 적합도의 측면에서 비교한다. 실제자료인 주식자료와 소비자패널자료에 이변량 일반화이항모형들을 적용한 결과, B-mB와 B-ebB의 성능이 우수한 것으로 나타나며, 그 중 상대적으로 넓은 허용범위의 급내상관을 가지는 B-mB가 선호된다고 할 수 있다. For bivariate binomial data with both intra and inter-class correlation, Danaher and Hardie (2005) proposed a bivariate beta-binomial model. However, the model is limited to the situation where the intra-class correlation is strictly positive. Thus it might be seriously inadequate for data with a negative intra-class correlation. Several authors have considered generalized binomial distributions covering a wider range of intra-class correlation which could relax the possible model restrictions imposed. Among others there are the additive/multiplicative and the beta/extended beta binomial model. In this study, bivariate models of the Sarmanov (1966) type are formed by combining each of those univariate models to take care of the inter-class correlation, and are evaluated in terms of the goodness-of-fit. As a result, B-mB and B-ebB are fitted, successfully, to real data and that B-mB, which has a wider permissible range than B-ebB for the intra-class correlation is relatively preferred.

본 연구에서는 연합강도의 차이에 의해 回想率이 영향을 받는 것인지 아닌지를 규명하고, 인출과정을 설명할 수 있는 타당한 원리를 좀 더 확실하게 고찰하고 있다. 1. The purpose of this experiment is to varify if the strength of association increases recall. 2. For the above purpose, the experimental procedure was as follows; 1) For one condition, subject learn the strongly associated pairs of input cue-target word in which input cues are strongly associated with the extralist recall cues but target words are associated rather weakly with recall cues. 2) For another condition, subjects learn the weakly associated pairs of input cue-target word. However the input cue-recall cue association strength and the target word-recall cue association strength are the same as the above condition. 3) After learning the lists of the word pairs, all subjects in both conditions are tested for recall, generation and recognition of target words with the same recall cues and they are tested for the formations of recall cue-input cue-target word chain. 3. The number of subjects are 80 college students of education major. 4. According to the results of the experiment, the strength of association affects neither recall, generation, and recognition of the target words nor the formation of recall cue-input cue-target word chain. 5. The possible conclusions are as follows: 1) Recall is not affected by the strength of association. 2) It seems to be inappropriate to explain the retrieval process in the light of associationism. 3) As the findings in this experiment and other similar experiments have shown, it might be more appropriate to explain the retrieval process with the generation-recognition principle.

The agricultural water demand that is calculated in present is difference with practical one by various situations in field. And, by various change, agricultural water demand can not estimate by agricultural land area simply. Considering various situations in field, calculated practical agricultural water demand and applied it to Korea Water Evaluation And Planing System (K-WEAP) in this study. The studied area is Seongju. The studied results showed that agricultural water demand calculate about 5.8 percent higher than existing one, and the agricultural water demand that is applied to K-WEAP calculate about 4~5.5 percent higher. Total Agricultural water demand increased about 0.5 percent until 2011.
