우리나라에서 사용하고 있는 표준형 부표류 중 스파부이는 등부표에 비하여 이출거리가 적고 항만 입출항로 및 협수로에서의 항로표시 기능은 좋은 편이나 강조류나 조차가 큰 해역등에서는 설치운영이 곤란한 실정이다. 이러한 스파부이의 장점을 유지하면서 단점을 보완하는 조위 순응형 스파부이의 개발이 절실한 시점이며, 이러한 항로표지의 요구를 만족하기 위하여 본 연구에서는 조위 순응형 스파부이를 개발하기 위한 전 해역의 환경조건을 검토하여 실제 해역에 적용가능한 스파부이의 구조형식을 제안하였다.

Seven cases of surgically proven sparganosis were serologically tested by means of microELISA for their specific IgG antibody levels. For that purpose, crude saline extract of spargana from snake, Natrix tigrina lateralis was prepared and used as antigen. The sparganosis sera were also tested with Paragonimus and Cysticercus antigens to observe the cross reactivity. A total of 71 sera from normal control, ectopic and pulmonary paragonimiasis, clonorchiasis, cysticerCOSIS and Taenia saginata cases were also included. Except for one case of old calcified infection, all of 6 human sparganosis showed higher serum levels of specific IgG antibody when the differential point of positive reaction was set at the absorbance value of 0.25 (the sensitivity being 85.7%). In control and other helminthic infections, all except 3 cases of T. saginata infection showed negative reaction to sparganum antigen (the specificity being 90.7%). None of sparganosis cases showed cress reactivity to Paragonimus and Cysticercus antigens. Undiluted cerebrospinal l1uid also showed high levels of antibody when central nervous system was invaded. The serologic diagnosis by means of micro ELISA could be a useful tool in epidemiological study of human sparganosis in susceptible population, as well as in individual diagnosis.

To observe the antigenic protein fractions in saline extract of Spirometra mansoni plerocercoid (sparganum), the crude extract was separated in reducing conditions of sodium dodecyl sulfate-polyacrylamide gel electrophoresis(SDS-PAGE). The proteins, transferred by celctrophoresis to introcillulose paper, were reacted with sera from 15 surgically confirmed sparganosis and 24 cysticercosis patients for immunoblotting. Out of 30 identified protein bands in the extract, bands of 29 and 36 kilodaltons (kDa) were the strongest and the most frequently reacting with specific antibody (IgG) in sparganosis sera. Bands of highter molecular weight also reacted with the sera but their frequency of reactions was lower. Sera of cysticercosis reacted with different protein bands in saline extract of sparganum, but the cross reactions were observed in strong antigenic bands of 29 and 36 kDa.

The circular composite tubes have been used as a main spar of HALE-UAV(High Altitude Long Endurance-Unmanned Air Vehicle). In this paper, an analytical model is presented for the prediction of the failure load of unsymmetrically stiffened circular spar using a modified Brazier approach. This model was used to predict the moment carrying capacity of the unsymmetrically stiffened circular spar. From the results, we can know that a stiffened cap placed in the top sector of a spar increased the bending capabilities. Four point bending tests were conducted to estimate the effect of the cap on the failure load and compared with the proposed model. And numerical simulations were performed to analyze the behavior of stiffened circular spar. Comparisons of the results from the proposed model with those from experiments and numerical modes show good correlation.

Out of many component proteins in crude saline extract of Spirometra mansoni plerocercoid (sparganum) , 36 kDa and 29 kDa proteins were found to be the most antigenic and were already purified by immunoaffinity chromatography using monoclonal antibody as a ligand. In this study, a single step purification of these potent antigenic proteins of sparganum extract was investigated. When the crude saline extract was charged to gelatin-Sepharose 4B affinity column, 36 kDa and 29 kDa protein fractions were bound. SDS-polyacrylamide gel electrophoresis (PAGE) and SDS-PAGE/immunoblot confirmed that the bound protein to gelatin was serologically pure. When evaluated by ELISA with patients sera, the purified protein of 36 and 29 kDa also showed improved antigenicity.

For the purpose of utilizing aspartame as sweetener of kimchi, the kimchi containing 0.01 to 0.08% aspartame was investigated by measuring pH, acidity, texture, color, sensory evaluation test during fermentation of 250days at 1$0^{\circ}C$, The pH of kimchi added aspartame was a little higher than that of control. The Hunter L-value of kimchi containing 0.01 to 0.04% aspartame was higher than that of control, and "a" and "b" values were also high in 0.06 to 0.08% and 0.01 to 0.08% treatments, respectively. The sweet taste and overall taste of kimchi containing 0.02% were suitable. In spite of the decrease of sweetener's degree by decomposition of aspartame during fermentation, the edible period of the kimchi by decrease of sour taste was also extended.e was also extended.

A seroepidemiologic observation of anti-Spirometrc erinacei plerocercoid (sparganum) antibody (IgG) in serum was made in normal adult and epileptic patients in Korea from february, 1987 to September, 1990. Sera were tested by enzyme-linked immunosorbent assay (ELISA) for anti-sparganum antibody together with anti-Taenic soEiun metacestode, and anti-Parusonimus westermcni antibodies. Sera reacted positively to sparganum antigen only were considered. Positive rate for anti-sparganum antibody in 850 normal adults was 1.9% (standardized rate by provincial population was 1.7%). In 2,667 randomly selected patients of epilepsy at 28 local centers of the Changmi Club, positive rate was 2.5% (standardized rate: 2.3%). In both normal adult and patient groups, the higher antibody rates were observed in Kangwon and Chonnam Provinces. Positive rates were 10 times higher in male than in female in normal adults and 4.5 times in male epileptic patients. The rates were elevated especially with age over 30-year. odd ratio of the antibody was 1.32 which indicated an ambiguous etiologic factor for epilepsy.

The migration and distribution pattern of spargana in mouse body was observed after experimental infection through mouth. The spargana were obtained from the snake, Natris tigrina lateralis, caught in Hoengseong-gun, Kangwon-do. A total of 28 male mice (ICR strain), 21∼259 in body weight, were fed each with 5 scolices (and necks) of spargana and killed after 10 minutes to 14 days. Systemic autopsy was performed on each mouse to recover the spargana. The results are as follows: 1. The spargana were found to penetrate into the stomach or duodenal wall of mice as early as 10 minutes after infection. They completed the penetration within 30 minutes and appeared in abdominal cavity. It was observed that spargana did not migrate tangentially along the gut wall but directly perforated the wall. 2. After 1 hour to 1 day the majority of spargana distributed in abdominal cavity of mice except a few which migrated to muscles or subcutaneous tissues. 3. It was within 7 days that nearly all of the spargana migrated to subcutaneous tissues. Out of total 28 in number found from subcutaneous tissues, 13 distributed around neck region, 12 around trunk and other 3 on head of mice and the most common sites were submandibular and subscapular areas. There was nearly no host tissue reaction to migrating spargana. 4. The initial length of spargana given was 4 mm in average but it increased to 12 mm after 7 days and to 35 mm after 14 days. The results suggest that spargana orally given to mice penetrate the gut wall within 30 minutes followed by escaping into abdominal cavity, and after passing through thoracic cavity or abdominal wall they anally Localize in subcutaneous tissues chieay around neck region within 7 days.
