The multimedia informations of text, image, motion picture, and audio are important as core elements for a efficient manipulation. The trademark image is one of the widely used multimedia data in business. A great number of trademark images have been used for a variety service. Therefore, the techniques of storing, retrieval and browsing are required for the Distribution System Management and the Physical Distribution Management. This paper propose the efficient retrieval system of the trademark image using both of the color and shape information.

A digital satellite communication channel has a strong nonlinearity with memory due to saturation characteristics of the high power amplifier in the satellite and transmitter/receiver filters used in the overall system, and can be well modelled by a nonlinear Volterra series. In this paper, we design and evaluate neural network based adaptive equalizers for compensation of nonlinearities in digital satellite communication channels. We consider CMLP (complex multi-layered perception). CRBFN (complex radial basis function network) and complex ρth order Volterra filter as equalizers, and evaluate their performances in terms of symbol error rate under various noise conditions. In particular, a complex hybrid learning algorithm of k-means clustering and LMS (least mean squares) algorithm is proposed for the CRBFN. Computer simulation results show good performance for all the equalizers considered

In order to use as a starter after drying, optimum growth conditions of Str. thermophilus and L. bulgaricus were investigated. The results were as follows. The growth of Str. thermophilus was reached at stationary phase after 12 hours incubation and L. bulgaricus was after 6 hours. Str. thermophilus was grown well, in the medium containing 10% of skim milk, 2%5 of sucrose, 0.1% of KCl and 0.015%(v./v.) of soy-sauce. In the case of L. bulgaricus, 10% of skim milk, 2% of glucose, 0.5% of bacto-peptone, 0.1% of K₂HPO₄ and 0.02% of pyridoxine was suitable for the maximum growth.

Creating Video Highlights provide the important role to the multimedia contents producers and multimedia users that want to create a shorter highlight video scene. This paper propose the new method of creating highlights and the content based video indexing, This indexing, exactly speaking, is event-based video indexing. We deal with soccer, basket ball, and handball that have the events of scoring a goal. The event rule was used to detect the highlight shot about scoring a goal. In video indexing, both of the virtual informations and the captionts are analyzed to create the sports video highlights.

한국판 소아 양극성장애 설문지 2.0(Child Bipolar Questionnaire 2.0)의 신뢰도 및 타당도 연구

Objectives : The Child Bipolar Questionnaire 2.0 (CBQ 2.0) is a rapid screener with a Core Index subscale of symptom dimensions frequently reported in childhood-onset bipolar disorder (BD) and scoring algorithms for DSM-Ⅳ BD, with and without ADHD, and the proposed Narrow, Broad, and Core phenotypes. This report provides preliminary data on the reliability and validity of the CBQ 2.0-Korean version. Methods : Core Index subscale to effectively predict diagnostic classification by structured interview was assessed using the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version-Korean Version (K-SADS-PL-K). Test-retest and inter-rater reliabilities of the CBQ 2.0 were assessed. Correlation of Korean Child Behavior Checklist (K-CBCL) with CBQ 2.0-Korean version was performed. Results : The CBQ 2.0 screening algorithms performed with a specificity of 66.7% and a sensitivity of 94.7% in classifying subjects with K-SADS-PL-K diagnosis of BD vs. no BD. The Core Index subscale had “good” agreement with K-SADS-PL-K diagnosis (Kappa=0.676) in identifying BD, ADHD-only, and no diagnosis. Conclusion : This preliminary data is from a sample derived from the child and adolescent psychiatric clinics, further validation is needed with community based samples in which childhood-onset BD is rarer and diagnoses more diverse. The CBQ 2.0-Korean version shows potential for rapid and economically feasible identification of possible childhood-onset BD cases as defined by DSM-Ⅳ criteria as well as by alternate disease phenotypes.

저자등은 인슐린의존형 당뇨병환자에서 임신중에 병발한 당뇨병성 케톤산증을 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다. IDDM is an autoimmune disease resulted from beta cell destruction and insulin deficiency, and developed mostly in children and puberty. Ketoaddosis remains one of the most senous complications that can occur in the pregnant diabetic. A 26-year-old woman, gravida 1, para 0, was admitted at 32 weeks gestation because of fever lasted for 6 days. She had been treated with insulin pump during the pregnancy. Blood sugar was well controlled before admission, and the etiology of her ketoacidosis was urinary tract infection and no insulin-intake. DKA was treated with fluids and intravenous insulin. Urinary tract infection was treated with antibiotics, based on culture test. Healthy newbom was later delivered by cesarean section due to fetal distress. We experienced a case of DKA in pregnant woman and report it with a review on literature.

The purpose of this study is to investigate the food habits and the dietary intake of female college students at day and night class in the Kyunggido area. The questionnaires were collected from 294 students(151 day class and 143 night class students) out of 350 in total. The results are as follows: Breakfast for day class students and breakfast and dinner of night class students were skipped more than 3 times a week. The main reason was short of time. In the behavior of food intake, the frequency of yellow-green vegetables, milk and seaweeds intake was low in all respondents. 18.4% of night class students ate out 3 times a day. In the kind of menu for eating out. Korean food was the most frequent, snack food the second, and fast food came last. 23.9% of students ate something 2 or 3 times a day between meals. The main reason for eating between meals was the desire to eat for day class students, and hunger for the night time students. Consumption of coffee was 0.76 cup a day. Daily mean of calory intake was 1,394 ㎉ and the ratio of carbohydrate : protein : lipid was 61 : 14 : 25. The intakes of iron and niacin of the day class students were higher than those of night class students. There was no significant difference in intake of other nutrients between day and night class students. Intake of calcium and iron did not reach 50% of Korean RDA.

In this study, rice candy was produced with mulberry leaf, and its effect on the lowering blood glucose level was assessed. The results were as follows: The recovery rate of mulberry leaf powder was 32.7%. The contents of crude protein, lipid, ash and crude fiber of mulberry leaf were 19.54%, 4.82%, 12.80% and 11.27%, respectively. The sensory evaluation revealed that the rice candy added with 1% mulberry leaf powder showed slightly higher palatability score than that of 2% but we decided that 2% addition of mulberry leaf powder would be preferred over 1% if considering both the physiological function and the sensory acceptability. The blood glucose level after ingesting the rice candy with mulberry leaf lowered by 31% more than that of control.

자동차 환경세의 장기효과 : 시뮬레이션 분석 Simulation Analysis

서정석,신윤근 한국환경경제학회 한국자원경제학회 2004 자원·환경경제연구 Vol.13 No.1

본 논문은 자동차에 부과된 환경세의 장기효과를 분석한다. 만일 정부가 소비자에게 자동차 배기가스에 포함된 오염물질이 대기오염 심화를 유발하는 외부적 피해의 화폐가치에 비례하도록 환경세를 부과하면, 일반적인 피구세와 마찬가지로 자동차운행이 사회적정수준으로 감소한다. 이와 같이 단기에 대기오염저감효과가 발생한다.게다가 이러한 환경세는 소비자들로 하여금 조세부담으로 인해 오염물질을 적게 배출하는 자동차를 선호하도록 하며, 기업은 이러한 수요 변화에 대응하기 위해 청정 자동차를 생산하게 된다. 그러므로 환경세는 장기에 대기오염저감의 추가적 효과를 갖는다. 이러한 결과는 자동차가 수평적 그리고 수직적 파별화되어 있을 때 내무해가 존재하는 과점모형에서 시뮬레이션을 통해 얻게 된다. This paper analyzes the long-run effects of an environmental tax levied on motor vehicles. If the government charges their consumers the tax as much as the monetary value of the external damage due to the pollutants emitted from motor vehicles, the operation of vehicles is reduced to the socially optimal level, alike to ordinary Pigouvian taxes. Thus, air pollution abatement is realized in the short run. Moreover, in the long run, the tax leads the consumers to prefer cleaner vehicles owing to the tax burden, and so the firms produce the motor vehicles with less pollutants emitted to meet the change of demand. Therefore, the tax has the additional effect on air pollution abatement. This result is obtained from the simulation in the oligopoly model which has an interior solution when the vehicles are horizontally and vertically differentiated.
