I have researched the formation of the Fishing ground, environment and catches of anchovy's long bag net fishery in 1978-1980 at Go Gun San Ir. middle west coast of Republic of Korea. The results are as follows. 1.The fishing ground environment during the fishing period, so to speak, the water surface temperature is 8-26˚.5c salinity is 28.4-32.9%o transparency 0.5-11m. There is a few difference between costal region and outward region. 2.It shows a tendency decreasing on the catches of Anchovy's long bag net fishery year by year. The monthly catches during the fishing period is May in spring July-Oct. in summer and autumn otherwise, it requires a survey of reserve resources in any other season. 3.On the appearance of anchovy at GoGunSan Ir. The small anchovy is formed a fish school at near coast during spring and autumn. It is connected with the spawning school. 4.The region "C" which the salinity density is lower as better catches, after July. The region "B" is better catches than any other place. 5. The transparency of fishing ground is 11m below. It is better catches is low transparency than the transparency is high.

In order to develop the curriculum of the fishery department in the fisheries Jr. college, We have collected and analyzed the domistic and foreign data adquated to the fishey department under the international trend, also we gathered the opinion from the inquiring paper investigation and consultation to the industrial field, concerned college and graduate during the 6 month from September 1982. The fishery department curriculum in fisheries Jr. college will be industrialized with the concerned technics and knowledge in relation to speciality of maritime affairs. Accordingly, we have developed the adquate curriculum which is practical and can be cultivated the technician to adopt in the industrial society.

In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.
Isolation of New Self-Cleaving Ribozymes with in vitro Selection
Cho, Bong-Rae,Lee, Young-Hoon Korean Chemical Society 2005 Bulletin of the Korean Chemical Society Vol.26 No.12
In vitro selection was used to isolate $Mg^{2+}$-dependent self-cleaving ribozymes with cis-cleavage activity from a pre-tRNA library having 40-mer random sequences attached to 5'-end of E. coli $tRNA^{Phe}$. After 8 rounds of SELEX (Systematic Evolution of Ligands by Exponential Enrichment), RNA molecules which can self-cleave at the high concentration of $Mg^{2+}$ were isolated. The selected ribozymes can carry out the self-cleavage reaction in the presence of 100 mM $Mg^{2+}$ but not in 10 mM $Mg^{2+}$. The cleavage sites of the ribozymes are located at +3 and +4 of $tRNA^{Phe}$, compared with +1 position of 5'-end cleavage site of pre-tRNA by RNase P. New RNA constructs deprived of its D stem-loop, anticodon stem-loop, variable loop and T stem-loop, respectively showed the cleavage specificity identical to a ribozyme having the intact tRNA structure. Also, the new ribozyme fused with both a ribozyme and $tRNA^{Leu}$ showed the cleavage activities at the various sites within its sequences, different from two sites of position +3 and +4 observed in the ribozyme with $tRNA^{Phe}$. Our results suggest that the selected ribozyme is not structural-specific for tRNA.

1,3,5-Tricyano-2,4,6-tris[2-(thiophen-2-yl)vinyl]benzene derivatives have been synthesized as a new type of octupolar nonlinear optical molecules and their linear and nonlinear optical properties were determined. The λmax values increa sed with the conjugation length and as the conjugation bridge was changed from phenyl to thienyl group. For phenyl and thiophene derivatives, the b value increased with conjugation length. In contrast, the $\beta$ values of the thiophene derivatives were much smaller than the corresponding phenyl derivatives.
