The purpose of this study was to identify learning strategies by learning style of first-year engineering students in order to find implications for teaching and learning strategies in engineering education. This study was conducted with 273 first-year students in two universities in Korea. Following were the results: First, there were Sensing learners(72.2%), Visual learners(84.6%), Reflective learners(64.8%), and Sequential learners(58.2%) and the level of learning strategies was 3.28(SD=0.38). Secondly, the finding revealed that there was only significant difference in learning strategies on Information processing dimension and Active students demonstrated higher level of learning strategies than Reflective students. To be more specific, there were significant differences in cognitive, meta-cognitive, and internal and external management. For engineering education, implications for teaching strategies in classroom and self-regulated learning strategies were discussed.

참가자미, Limanda herzensteini는 가자미목 (Pleuronectiformes), 가자미과 (Pleuronectidae)에 속하며, 우리나라의 동해, 일본의 세토내해 이북, 중국 및 사할린 근해에 분포하는 어종이다. 본 종은 연안정착성 어종으로 동해안에서 낚시 및 저인망 어업에 의해 어획되는 산업적 가치가 큰 고급어종이며, 저수온에 강하여 한류성 해역에서의 양식 가능성이 매우 높다고 할 수 있다. 또한 최근에는 참가자미의 자원량 감소가 두드러지고 있으므로 자원증강이 절실히 요구된다. 이 연구에서는 주 어획지역인 강원도 주문진 인근해역에서 1998년 9월부터 1999년 10월까지 자연산 참가자미의 연간 생식소중량지수의 변화를 조사 하였으며, 조직학적 조사에 의한 생식소 발달과정과 생식주기를 밝혔다. 정소는 정소엽 형태이며, 각각의 정소엽은 여러개의 소낭구조를 가진다. 각 소낭내의 생식세포들은 같은 단계의 발달상태를 보인다. 난소는 원추형의 낭상으로 체강벽에서 연결되는 난소간막에 의해 부착되어 있으며, 내부는 결체성 조직인 다수의 난소박판으로 구성되며, 이곳에서 난원세포가 유래한다. 수컷의 GSI는 1월에 가장 높았으며, 암컷의 GSI는 3월에 가장 높은 값을 보였다. 생식주기는 성장기(6~9월), 성숙기(10~12월), 완숙 및 산란기(1~3월) 그리고 회복 및 휴지기(4~5월)로 나눌 수 있었다. 난모세포의 발달양식은 난군동기발달형에 속하였다.

Two forms of sea mustard, Undaria Pinnatifida were cultured in order to compare the morphological characteristics and the efficiency of production. U. Pinnatifida f. distans was collected from Wando, Korea and U. Pinnatifida f. typica was transplanted from Sanriku, Japan. The latter form grew faster in length and weight than the former. Maximum growth was shown in early April for both forms, and the growth rates decreased after this. Absolute growth rates between the two forms were quite different. Average total lengths at the harvest season was 161.1cm in U. Pinnatifida f. distans and 183.5 em in U. Pinnatifida f. typica and average weights of those two forms were 1,003.4g and 1,314.6g, respectively. The weight of available parts for the salting process of the two forms were 734.8g and 968.5g, respectively. The rates of total length versus the length of the available part of the two forms were $76\%$ and $83\%$, respectively and those of the total length versus weight of the available part of them were $43.8\%$ and $52.7\%$, respectively. The results of this study suggest that the U. pinnatifida f. typica had more available part per unit weight than that of the U. pinnatifida f. distans for the efficiency of salt processing.

This study examined student's and teachers' perceptions of learning style on internet-based learning. Many research have studied student's learning style both in traditional learning settings and inter-based learning settings. These studies emphasized that student's learning style is one of the important indicators of establishing learning strategies and expecting positive learning outcomes. However, it has been rare to find the comparative analyses between learners and teachers to see how differently they perceive the learning style on internet-based learning. This study analyzed 386 elementary and 627 middle school students and 130 cyber teachers. They filled out the 15 items questionnaire on internet-based learning style. The results showed that the student's and teachers preferred the self-directed internet learning style rather than cooperative and dependent styles. However, the teachers judged the students more self-directed and dependent style preferred than the students self perception. In conclusion, this study suggests the differentiated teaching-learning design and development strategies on internet learning, especially based on subject matter. Also, there should be advanced tutor strategies considering learners' different learning styles. Finally, many research on internet learning styles should be conducted in various learning areas and learner ages and characteristics.

On the basis of Sternberg's theory of mental self-government, this examined the difference in thinking style between gifted science students and non-gifted students, and their earth science concepts by the different types of thinking styles. The subjects were consisted of 120 students from the Busan Science Academy and 122 students from two general high schools in Busan, Korea. All participants responded to the Thinking Styles Inventory which is a self-report test consisting of 65 items, and essay questions for examining the students' earth science concepts. The results are as follows. First, the gifted science students prefer legislative, judical, anarchic, global, and liberal styles, where non-gifted students prefer executive, oligarchic, and conservative styles. Second, Type I thinking style group prove to have more complex concepts in relation to the geological and astronomical areas than those of the Type II thinking style group in both of the gifted and non-gifted students. This indicates that Type I thinking style students use a deep learning approach where Type II thinking style students use a surface learning approach.

Infectious Pancreatic Necrosis Virus (IPNV) is one of the most important pathogens for inland fish farming and had been first reported in Korea from returning adult chum salmon (Oncorhynchus keta) at hatcheries on the east coast. During the past years, several viruses identified as IPNV were isolated not only from chum salmon, but also from gold fish (Carassius auratus), eel(Anguilla japonica), and rainbow trout (Salmo gairdneri). An isolate, coded DRT, from fingerlings of pan-cultured rainbow trout in Daechung Dam showed different serotype from three known reference serogroups of IPNV such as VR-299, Sp, and Ab. Antisera to three of these serotypes, however, partially neutralized the infectivity of this isolate. Anti-Sp type was rather effective than either anti-VR-299 or anti-Ab, implying DRT could be more closely related to Sp. DRT has been purified and its RNA genome segments were compated showing that the isolate does not belong to any of known serogroups even with some common antigenicity.
