Seasonal variation of Chaetognaths in the coastal waters off Kori, was studied. Samples were collected monthly during the period from March 1988 to February 1989 at 30 stations. Ten species belonging to three genera were identified: Sagitta crassa, S. nagae, S. enflata, S. minima, S. regularis, S. robusta, S. neglecta, S. ferox, Pterosagitta draco and Krohnitta pacifica. Mean abundance of chaetognaths changed monthly from 0 to 165 individuals m^-3. The predominant species varied with month; Sagitta crassa occurred abundantly from April to July, S. enflata from August to November and S. nagae occurred throughout the year except for March.

Studies on the spatial distribution of chaetognaths have been carried out on the based of materials collected in the Yellow Sea in Auguest, 1982. As a result, 5 species belonging to two genera occurred; Sagitta crassa, S. enflata, S. nagae, S. regularis and Krohnitta pacifica. A key to the chaetognaths are given. Sagitta nagae was revealed to be a indicator species of the purturbed area formed by the mixing of the warm water current and neritic waters in summer season in the Yellow Sea.

Background: The guidelines for asthma treatment have been developed but few primary care physicians (PCPs) practice in accordance with these guidelines. Objective: This study surveyed the change of their understanding of asthma before and after using a novel computer software program named as Easy Asthma Management (EAM) program. Method: One hundred of total 363 physicians, who used EAM program for at least 3 months, responded to a self-reported instrument. Survey was conducted in August 2004 through October 2004, and in October 2004 through January 2005 before and after the use of EAM program. Result: The use of EAM program changed the understanding on the asthma treatment according to the survey282 result that 85% of participant PCPs agreed to follow the EAM guidelines more strictly. Especially, results showed that their attitudes were changed as follows: anti-inflammatory agent-based prescription from 38% to 49%; inhaler-based prescription from 43% to 55%; continuous treatment from 21% to 43%. Additional results showed that they diagnosed asthmatic patients more easily (from 40% to 49%). Conclusion: The use of EAM program changed the understanding and treatment on the asthma by PCPs, which resulted in increased prescriptions of inhaled anti-inflammatory agents and more objective evaluation of the changes in the conditions of asthmatic patients.

To study the distribution of chaetognaths in Ice Edge Zone near the Antarctic Peninsula during austral summer, samples were collected at 35 stations between Bransfield Strait and northwestern Weddell Sea from December, 1993 to January, 1994. Chaetognaths were consisted of three species, Enkrohnia hamata, Sagitta gazellae and Sagitta marri. The abundance of chaetognaths was 0∼1,359ind./1000㎥ and high values were observed in the northwestern Weddell Sea. Eukrohnia hamata and Sagitta gazellae were distributed widely in Bransfield Strait and northwestern Weddell Sea. The abundance of Eukrohnia hamata was high in northwestern Weddell Sea but it was dramatically dropped in the Bransfield Strait. The abundance of Sagitta gazellae was high in Gerlache Strait and northwestern Weddell Sea and S. marri was very low and showed restricted distribution. The vertical distribution of chaetognaths were mainly confined to 150m and highest density were found in bottom water.
