In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

Students' alternative concepts of evolution are similar to misconcepts and disputes which scientists had in science history. The aims of this study are to analyze the elementary children's concept in evolution based on science history. Lee (2004)'s two tests were applied to 6th grade to investigate the children's evolution concepts and genetic concepts related to the historical development of the evolution concepts. The test results were analyzed in accordance with 4 stages of science history based on Lee (2004)'s method. These stages are divided to stage 1 (Before Lamarck), stage 2 (Lamarck), stage 3 (Darwin), stage 4 (After Darwin). The major results are as follows. Most of elementary school children are fixed to the stage 2. They usually do not show the consistency of evolution concepts in the three dimensional aspects such as mechanism, time, and subjects. Many children do not have concrete meaning of gene, inheritance, sexual reproduction, mutation and could not connect these concetps and process of evolution. Also, they believe the inheritance of acquired traits and spontaneous generation. Therefore it is confirmed that they still have similar misconcepts and disputes which scientists had in transition time between stage 2 and 3 and most of children already have strong Lamarckian thought acquired from daily life experience before learning about natural selection and evolution.

This research was aimed to develop and apply the molecular genetics teaching program based on the history of science and creative problem solving model (HS-CPS model) for gifted students. Based on the strategies of creative problem solving and scientific theory development, the HS-CPS teaching program were developed. This program was applied to 8 first and second graders of the special class for invention activity in a high school. Creative problem solving ability in science and the understanding of DNA and gene concept were tested in pre and post of 12 lessons. The results were as follows: First, creative problem solving ability in science was improved meaningfully. Second, HS-CPS teaching program was effective in the understanding of DNA and gene concepts. Third, the students responded positively to the program evaluation questionnaire.

Chronic eosinophilic pneumonia(CEP) is a rare disease of unknown etiology characterized by chronic infiltration of the lung with eosinophils. It presents with profound systemic symptoms comprising fever, night sweats, weight loss, dyspnea and blood eosinophilia with nonsegmental air-space consolidation confined to the outer third of the lung, the "photographic negative of pulmonary edema". Histopathologic features of chronic eosinophilic pneumonia are intraalveolar and interstitial infiltrations with eosinophils, histiocytes, giant cells, scattered lymphocytes and plasma cells. Glucocorticoid therapy cause prompt resolution of symptoms as well as disappearans of blood eosinophils, elevated serum Ig E levels and the roentgenographic lesions. Infrequent radiographic findings include nodular infiltrates, consolidations, cavitations, atelectasis and pleural effusions. Deaths from CEP although rare, have been reported, but the majorities of CEP have benign courses and do not need a therapy with ventilator. We report a case of chronic eosinophilic pneumonia, which had a sudden course associated with diffuse pneumonic consolidations on the both lung and bilateral pleural effusion.

This is to develop the regionalized regression model which relates annual maximum flood peak flows to basin characteristics, and to estimate the magnitude and the frequency of river floods at the stage gaging stations selected by considering whether the flow is in natural condition. The representative watersheds selected for the study of flood freguency analysis are the Han, the Geum, the Yeong san, the Som jin and the Nak tong River basin. The magnitude and frequency of each station floods in the river basins are estimated by annual maximum series method, and are compared with sampling variances to calibrate the suitability of the flood estimates. The regionalized model in regional frequency analysis which relates annual maximum flood analysis which relates annual maximum flood flows to basin characteristics at gaging stations is developed and presented by using the generalized regression analysis method. The result of the study will contribute to providing various hydrologic information for the planning and the design of the hydraulic structures and the improvement of the river project.

본 연구는 allelopathic potential을 지닌 벼의 교잡종을 포장에서 재배하여 그 식물체의 잎을 생물검정에 이용하여 allelopathy 효과 유무를 검정하고, 생물검정으로 선발된 교잡종을 대상으로 phenolic compounds를 조사하여 allelochemical로써의 가능성을 확인하고 나아가 phenolic compounds 생합성에 관여하는 효소의 활성 측정과 이 효소의 작용에 의해 유도되는 phenolic compounds를 구명한 결과는 다음과 같다. 1. 포장상태에서 피를 대상으로 생물검정을 실시한 결과 양친으로는 Kouketsumochi, Woo cochin yu에서 공통적으로 90% 이상의 높은 피뿌리 생장 억제율을 보였고, 교잡종에서는 Kouketsumochi/Woo co chin yu, Dongjinbyeo/Kouketsumochi Dongjinbyeo/Woo co chin yu 조합에서 80% 이상의 높은 억제율을 나타냈다. 2. Kouketsumochi의 PAL 활성은 protein 1kg당 63.46μkats로 타 공시품종보다 높았다. 또한 Kouketsumochi와의 교잡종도 타교잡종보다 높은 것으로 나타났다. 3. Kouketsumochi의 cinnamate 함량은 생체중 1g당 2.64μg으로서 다른품종이나 교잡종보다 2∼5배 높았고, Kouketsumochi와의 교잡종도 타교잡종보다 높았다. This study was conducted to investigate allelopathic potential of various crosses of rice cultivars using their inhibitory effect on barnyardgrass growth under field conditions, and to determine PAL activity and phenolic compounds involved in phenylpropanoid pathway from selected crosses of rice cultivars. Under field conditions, Kouketsumochi, Woo co chin yu possessed higher allelopathic potential inhibiting over 90% of barnsyardgrass growth. Crosses of Kouketsumochi/Woo co chin yu, Dongjinbeyo/Korketsumochi, Dongjinbeyo/Woo co chin yu showed over 80% inhibitory effects on barnyardgrass growth. The highest PAL activity, 63.46μkats/kg proteins was detected in Kouketsumochi which is the most important enzyme in phenylpropanoid pathway and also higher PAL activity in crosses with kouketsumochi. Content of cinnamate was 2.64㎍/g f.w. in Kouketsumochi which was 2 to 5 times higher than other rice cultivars tested, indicating that higher PAL activity resulted in more cinnamate. The similar trends in cinnamate content and PAL activity were observed in crosses of rice cultivars with Kouketsumochi.
