The prevalence of PPNG among pretreated gonorrhea cases isolated at the STD clinic of Choong-Ku Public Health Center in Seoul has been studied and reported annually since 1981. In 1991, 123 strains of N.gonorrhoeae were isolated, among which 58(47.1%) were PPNG. In 1992, 98 starains of N.gonorrhoeae were isolated, among which 51(52.0%) were PPNG. In all, 109(49.3%) strains were found to be PPNG among 221 strains isolated between 1991-1992. The prevalence of PPNG in Seoul showed increased tendency till 1989, thereafter, it has been stationary or slightly decreasing.

Ocean tourism is rising as a new leisure activity pattern thanks to increased income level and leisure time. Korea is surrounded by the sea on all sides but one, however, we are in beginning stage for the development of ocean tourism resource. In order to meet the demand for ocean tourism that increases yearly, a facility is needed that can satisfy various activities and desires at ocean. Especially, it would be effective to develop fishing port into ocean tourism site, as it's equipped with natural view, cultural resource and industrial facility regardless the role of fisheries base. This study, therefore, will investigate on the function and value of fishing port, and review on the advanced foreign country's cases in order to grope for utilizing fishing ports scattered in Korea into ocean tourism resource.

Small bowel leiomyoma is a rare tumor which may occur wherever smooth muscle is present. The small bowel is the most common site and it makes up 20~30% of all benign small intestinal neoplasms. A spectrum of symptoms are common ranging from nausea, vomiting, abdominal pain, to massive intestinal bleeding. Bleeding is the most common symptom and is usually gross and recurrent. Occasionally it may be life threatening. But, the most serious problem is both the absence of specific clinical symptoms, and the difficulties shown in radiological diagnostics of the small bowel. If conventional diagnostic methods fail to reveal any positive findings for gastrointestinal bleeding, the diagnosis of intestinal leiomyoma should be suspected and an SMA angiography shoud be performed. The angiographic criteria of small bowel leiomyoma is very characteristic. We present a case of leiomyoma with considerable and prolonged gastrointestinal bleeding, which was diagnosed by angiography. A 61-year old woman was admitted with a history of melena over the last 10 days. An SMA angiography showed a hypervascular mass with a diameter of 3×3cm. A segmental resection was performed under the impression of the gastrointestinal bleeding due to leiomyoma of the small bowel. Microscopic examination of the lesion shows interlacing or whorl bundles of spindle shaped ces and no mitosis.

Study on the synthesis of chemical nucleases that have ability of cleavage of RNA or DNA to investigate the structure of nucleic acids was performed. We synthesized Ni-complex that was synthesized by Karn and Busch (1966) and identified the specificity and ability as chemical nuclease by Chen. et. al. (1993), and Cu-complex and Cd-complex that were presumed as having specificity similar to Ni-complex in terms of the structure and specificity and ability as chemical nuclease. The spectra of synthesized new transition metal complexes were compared with those of Ni-complex. Results of comparing data of UV and IR spectra of Cu-complex and Cd-complex with those of Ni-complex showed that the structures of newly synthesized transition metal complexes were similar to the structure of Ni-complex. The yield of synthesis of Ni-complex, Cu-complex, and Cd-complex was 81%, 7%, and 39% respectively.

GNY logic is well-known work to analyze cryptographic protocols as formal verification method. But GNY logic has limitation which can't analyze public-key based key establishment protocol. In this paper, we represents an extended GNY logic to analyze key agreement protocol and to verify key confirmation. We also simulate two example protocol to illustrate soundness of this logic. Our experiments is semi-automated behavior assisting complicated analysis and verification work by using extended GNY logic.

Udo and Schemeori oreum[cow's head rising]: "Cow's head rising" and "Cow's head mountain" have both a shape just like a cow is lying and considering that two places' geographically high location and its district name are also configurative, we can sense landscape Image as a "a cow-shaped island lying down" and Jeju I slanders' unique consciousness of the geographical features. Udo Palkyong[eighl picturesque sights at Udo]ail shows a format of "poem-recitation-after titling" consisting of a lour-Chinese-letter word derived from the ancient history as a format for semantic access, but if we take a little closer look at it, it is noted that Udo Palkyong turns to be ontological subject of landscape mainly targeting formative elements. Therefore, in formative sense, Udo Palkyong belongs to China's famous sight experience type, but as for the contents, it is much closer to famous landscape type haying the formative elements like Gwandong Palkyong or Danyang Palkyong as major landscape elements. It was found that the seven landscapes centering on Hanlasan Baerokdam[a crater lake on top of Halasan], except Cheonjingwansan brook haying three landscapes, iorm their landscape within a 0.87-kilometer radius. In addition, as for viewing composition pattern, there are live panoramic landscapes which reflect the features of Seaside Landscape; two geographical landscapes. and one focal landscape. Besides, the prospect type consists of mostly landscape type and far-and-wide viewing type. As for landscape format, there appear a variety of features of main landscape subject's visibility areas from a distant view to a short-range view, and also structural properties within the physical, landscape, visual, psychological influence. In addition, there appear a variety of viewing compositions, such as the five panoramic landscapes, two detailed landscapes, and one geographical landscape. We can trace a vestige of a tense atmosphere of bodhisattva's death and the pursuit of stability of dialectical composition. Conclusively, Udopalkyong is well expressive of aesthetic characteristics, at a viewpoint of time and space, boasting of exceptional landscape quality regardless of day and night, heaven and earth, front and rear, and at whatever direction Udopalkyong may be viewed.

Reinforced concrete(R/C) is commonly used to structures because they have many merits that compressive strength, economy and so on. However, reinforced concrete has a crack at the tensile section which is due to the relatively lower tensile strength than its compressive strength. Latex modified concrete(LMC) has higher tensile and flexural strength than the ordinary portland cement, due to the interconnections of hydrated cement and aggregates by a film of latex particles. The purpose of this study was to investigate the flexural behavior of reinforced concrete beam with latex modified concrete, having the main experimental variables such as concrete types(ordinary portland cement concrete, latex modified concrete), latex contents(0%, 15%), flexural steel ratios(0.012, 0.0235), and with/without shear reinforcement. The beam of LMC showed considerably higher initial cracking loads and ductility than that of OPC, but, similar to ultimate strength and deflection. This might be attributed to the interlocking of hydrated cement and aggregates by a film of latex particles, water retention due to hydrophobic, and colloidal properties of the latexes resulting in reduced water evaporation. The beam with latex modified concrete could be adopted at field for controlling and reducing the tensile crack due to its higher tensile strength.

Leaching and adsorption equilibria of Sr Chemical Species from the near field of a repository has been studied in solidified cement with Fe and oxidized Fe. The absorption percent, Ads %, and distribution coefficient, K_d were calculated using equilibrium concentration to predict the extent of leaching and adsorption. In the mixed aqueous solutions the Ads % increase as Cement(C)/Water(W) ratios increase and K_d was decreased for Sr. These behaviors were discussed by adsorption and equilibrium of spiked ions. Oxides Fe promoted adsorption of spiked ions, but pure Fe had no effect. E_h values were also estimated and discussed to elucidate oxidation-reduction environment of experimental system.
