1993년 4월 부산시 부산 공동어시장에서 채집된 전갱이과 어류 1개체가 등지느러미와 뒷지느러미에 1개의 작은 토막지느러미가 있는 점에서 전갱이아과 Caranginae에 속하는 종으로, 가라지속 Decapterus의 한국 미기록종인 홍기가라지(국명신칭) Decapterus tabl로 동정되었기에 이를 기재하였다. 본종은 상대적으로 측선이 완만한 경사를 이루고, 측선의 경사 부위에 모비늘이 없으며, 측선 모비늘수가 34-48개이고, 두정부의 비늘은 안구의 중앙 뒤쪽까지 분포하고 있다. 또한 복추골에 2개의 측돌기공 및 꼬리지느러미가 적색인점 등이 동일 속의 다른 종들과 잘 구분된다.

This study includes the taxanomy, description and a key to species of mites in the family Bdellidae from Korea. Specimens were collected at 60 localities in Korea from January, 1994 to June, 1997. As a result of this study, the following 7 species were identified : Bdella longicornis ( Linnaeus, 1758), Bdella muscorum Ewing, 1909, Cyta latirostris (Hermann, 1804), Biscirus thori Womersley, 1933, Spinibdella tenurostris (Ewing, 1914). Six species excluding Bdella muscorum of them are newly recorded from Korea.

Purpose: This ethnography was conducted to describe the meaning of illness of the elderly in traditional folk healing performance. Method: This study was guided by Klienman's explanatory model of health care systems. The fieldwork was conducted in an agricultural clan of Namwon City from January of 1990 to Feburary of 2001. Research data were collected by Ehnographic interview and participant observation. Participants of this study were 10 elders aged 74 years old to 96 years old; two of them were male. The data were analysed with the techniques of taxanomy, flow and decision, and proxemics. Result: The meaning of illness was categorized with four compononts, that is, ritual for life, defeat and failure in power game, humiliating punishment for guilt, and Tal. Conculsion: These meanings were constructed on physical and socio-cultural environment of this clan. The healing strategies were determined based on the meanings of illness. These results can be used to understand the health behavior of the elderly and thus ensure the quality of nursing for the elderly.

This study includes the taxanomy, description and a key to species of mites in the genus Asca from Korea. Specimens were collected from December 1993 to May 1996. As a result of this study, the following three species were identified. 1. Asca (Asca) aphidioides (Linne, 1758) 2. Asca (Asca) sculptrata Aoki, 1968 3. Asca (Asca) garmani Hurlbutt, 1963 These three species have not been described from Korea.

To understand physical structures in the Korean waters, we investigated the spatio-temporal distribution of Pontella species known as indicator species of water mass using a David-Hempel neuston net from April 2002 to March 2003. Five Pontella species (P. chierchiae Giesbrecht, P. fera Dana, P. latifurca Chen and Zhang, P. securifer Brady and P. sinica Chen and Zhang) were found. Their abundance increased from May to October with increasing the surface water temperature. Pontella chierchiae predominantly appeared in the whole areas while P. latifurca scarcely occurred in coastal waters. The other three species (P. fera, P. securifer and P. sinica) were rarely found in the South Sea of Korea on August to September. We suggest that P. securifer and P. fera as oceanic species can play a role in an indicator species of the Tsushima Warm Current while P. sinica as Chinese coastal species is affected by the diluted waters of the Yantze River. We also provide re-description of the three species (P. chierchiae, P. fera and P. latifurca) insufficiently described and discuss their zoogeography.

This purpose of study is to identify types of study groups in online learning and the relationships between the types and teams' performance. In order to address these research questions, four study group types are developed based on Neiderman & Beise(1999)'s typology: 1) fully-supported; 2) highly-virtual; 3) traditional; and 4) inactive. And then three study group types are identified based on taxonomy-approach using cluster analysis from 46 teams participated in this study: 1) fully-supported; 2) traditional; 3), and 4) highly-virtual. The result shows that the groups are validated in the latter, except for the inactive type. The result indicates that fully-supported type groups achieved the highest performance, while the highly-virtual type group achieved the lowest performance.

Objectives: We evaluated the learning objectives of dental hygiene courses based on Bloom's learning objectives, and analyze the degree of match with the dental hygienist's job for each detailed subject. Methods: The 5th edition of 'Dental hygiene and learning objectives' was analyzed by subject based on Bloom's cognitive domain classification from March 10 to April. In addition, the degree of match between the contents of the secondary job analysis of the dental hygienist and the learning objectives for each detailed subject were analyzed. Results: The total number of dental hygiene learning objectives was 2,975 (2,762 theory, 52 practice). Among the cognitive domains, the comprehension domain was the most common (79.8%), and the skill domain was very low (4.9%). In the job for each detailed subject of dental hygiene, the most frequently performed was 'dental prophylaxis and practice' with 103 subjects. Conclusions: Overall, dental hygiene learning objectives are mostly theory-oriented, so it is necessary to expand and improve in the direction related to the jobs that clinical dental hygienists perform in the field. In addition, it is necessary to continuously develop timely learning goals, and prepare active strategies for developing high-quality items.

Clay mineralogical properties, soil formation and classification for the limestone derived soil were discussed from the 4 soil series, Pyeongchang, Anmi, Yulgog, and Mungyeong, distributed over the area of Bangjeol-Ri, Yeongweol-Eup, Gangweon-Do. The results are as follows; 1. Kaolinite and Al-interlayered vermiculite were the main clay minerals and other minerals were illite, vermiculite, and chlorite. 2. CEC of topsoil ranged from 10.5 to 22.9me/100g and that of sub-soil ranged from 10.0 to 23.8me/100g. CEC seemed to be increased with descending from topograpical position and had slightly significant positive correlation. 3. Lithologic changes as a runction of soil depth showed smooth change for Pyeongchang, discontinuity for Anmi, unpredictability for Yulgog, and uniformity for Mungyeong series. 4. According to the new system of soil taxanomy Pyeongchang series was classified as Typic Hapludalfs, Anmi as Fluventic Eutrochrepts, Yulgog as Fluvaquentic Eutrochrepts, and Mungyeong as Aeric Haplaquepts.

This experiment was carried out to distinguish between picea abies (L.) Karsten and Picea koraiensis Nak by the method of discriminant analysis which is used the metrical continuous characteristic on current inorphological plant taxanomy. The results are summarized as follows 1) The discriminant function and discriminant region from the experiment are Z(x)=Z($x_1,\;x_2$)=$0.000379x_1+0.004354x_2-0.311061$ or Z(x)=Z($x_1,\;x_2$=$0.000379(x_1-60.442800)+0.004354(x_2-66.185100)$, $$R_1=(x{\mid}0.000379x_1+0.004354x_2-0.311061{\geq_-}0)$$, $R_2$=($x{\mid}0.000379x_1+0.004354x_2-0.311061$ <0). 2) The probability of misclassification based on the above discriminant region is P($2{\mid}1$)=$P(1{\mid}2)$=0.444 therefore the probability of simultaneous misclassification of P($2{\mid}1$) and $P(1{\mid}2)$ is about 44.4%. 3) the probability of misclassification by the discriminant function resulted from the experiment if recorded as high but it is thought that there is a considerable meaning to perceive the probability of confidence about the discrimination better than its precision.
