The autoinfective filariform larva of Strongyloides stercoralis causes hyperinfection in immunosuppressed hosts. Here we report on the case of a male patient who was admitted to the emergency room at Gwangju Veterans Hospital with a complaint of dyspnea, and who was receiving corticosteroid therapy for asthma. Many slender larvae of S. stercoralis with a notched tail were detected in Papanicolaou stained sputum. They measured $269\pm21.2{\mu}m$ in length and $11\pm0.6{\mu}m$ in width. The esophagus extended nearly half of the body length. The larvae were identified putatively as autoinfective third-stage filariform larvae, and their presence was fatal. The autoinfective filariform larva of S. stercoralis has not been previously reported in Korea.

A case of Strongyloides stercoralis infection was experienced in a 73-year old Korean female patient, was hospitalized with relapse of cholecystitis. The patient developed cough and dyspnea 17 days after the admission. On the 27th hospitalized day, diarrhoea, nausea, vomiting and abdominal pain started. A number of parasitic larvae were incubated at $25^{\circ}C$ for 2 days. Typical fork tailed filariform larvae of S. stercoralis (Bavay, 1876) Stiles and Hassall, 1902, were identified after cultivation. There was no improvement of diarrhoea after the medication with mebendasole. After the administration of thiabendazole, however, diarrhoea was stopped. On the 6th day of medication, S. stercoralis larvae was no more detected, and thereafter no larva was observed by repeated stool examinations upto 2 months after chemotherapy. The patient had the history of administration of steroid for articular rheumatism. Therfore this ,case seems to be a hyperinfection of S. stercoralis due to an autoinfection and to be the first report on the hyperinfected strongyloidiasis in Korea. Related literature was briefly reviewed.

Nine cases of human infection with Strongyloines stercornlis are reported among patients admitted to the Seoul Paik and Sang-Kye Paik Hospitals, Inje University, from April 1990 to Junuary 1992. The Patients, 7 males and 2 females acted between 50 and 70, either had the history of long term use of steroids for management of arthritis, or were complicated with other chronic diseases such as hypertension, liver diseases, psychotic disorders, and gastrointestinal problems. All of the nine patients revealed rhabditoid larvae of S. stercorolis in fecal examination. A 57-year-old woman who complained of arthritis and abdominal discomfort, was treated with albendazole and mebendazole, and on the 4th and 5th treatment day 220 parasitic adult females were collected from the diarrheal stool. The patient had a long history of administration of steroids for treatment of arthritis, and seems to have suffered from hyperinfection syndrome due to autoinfection with S. stercordis. This is the 3rd report on the recovery of parasitic adult females of S. stercoraLis in Korea.

Until now, korean aquaculture industry has been grown largely from a quantitative viewpoint. However, an increase of quantity has caused lots of problems producing a derived effect recently. Nearly 82% of korean aquaculture farms had been installed mainly at inshore of the southern sea and also sewage, factory wastes, high density of fishcage at the limited area and autoinfection have deteriorated inshore fisheries. The offshore have been on the rise for the solution to these problems since it has clear seawater reduces the environmental pollution with much current. As a matter of fact, the existing inshore fishcage facilities have trouble advancing to the offshore due to the rough environmental conditons such as a high sea, strong currents etc.; therefore, it is necessary to develop a new cultivating equipment fit the open sea conditons. In this research, the theoretical study and experimental analysis have been carried out for the fishcage design of the structure which is able to use at the open sea.
