The purpose of this paper is to investigate key ethical issues and hindrances to ethical behavior faced by professionals working in Korean insurance industry. For this purpose, conducted is a survey of actuaries in a variety of positions in insurance companies and insurance related institutions. The findings also are compared to those of American studies. Actuaries' perceptions of the key ethical issues tend to be restricted to actuarial aspects such as insufficient legal authority to perform professional services in an ethical manner and failure to get adequate ethics training program. But some issues arising in marketing are considered significant similar to the U.S. As a whole, key ethical issues and challenges are not significantly different from the viewpoints of actuaries working in the life and non-life insurance business. Regarding key hindrances to ethical behavior, the 15 factors are presented such as competitive pressures, performance-based evaluation and unethical demand made by clients. These findings are generally similar to those of the U.S. studies.

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.

There are many theoretical indices for chemical carcinogenicity. Among the various indices, the LUMO electron density and approximate superdelocalizability have taken to compared and discussed for the carcinogenicity of PAHs, aromatic amines and Azo-compounds. The sum of LUMO electron density of the trans-butadiene type 1, 2, 4 positions in a molecule has been known to be in more agreement with the observed values than those of approximate superdelocalizability. It is suggested that any trans-butadiene type 1, 2, 4 positions play an importmant role in the elucidation of mechanism of chemical carcinogenesis.

Background : Previous data have been reported that subtype B is prevalent in South Korea, but neither the extent nor the proportion of subtypes could be evaluated. This study was designed to analyze the distribution of HIV-1 subtypes, temporal instructions and transmission dynamics between epidemiological groups. Methods : 1,280 Koreans had been diagnosed as HIV seropositive during the period 1985 to 2000. Among them, 134 individuals were selected for this molecular epidemiological study. 134 DNAs were isolated from uncultured or cultured peripheral blood mononuclear cells. V3-V5 (0.7 kb) fragment of HIV-1 env gene was amplified by nested polymerase chain reaction and was sequenced. Results : HIV-1 isolates from thirty-seven homosexuals were all subtype B (100%). On the other hand, 66 isolates from 94 heterosexuals were subtype B (70%) and 28 were non B subtypes (30% : 13 A, 4 C, 2 D, 8 E , 1 G). Only subtype B strains were isolated from 73 males who were infected with HIV inside Korea while 16 B and 20 non B subtype strains were isolated from 36 males who were HIV infected outside of Korea. However, B and non B strains were isolated half and half from females who were infected inside Korea except one. Conclusion : The HIV-1 subtype B strains are prevalent in Korea from the early HIV infection until present in both homo and heterosexuals. Non B strains have been transmitted from men who were infected outside Korea to their spouses and casual partners. So, we need further study to monitor subtype B and non B HIV transmission in epidemiological groups of Korea, (Korean J Infect Dis 33:311∼318, 2001)

Significant improvements in bond strength between new and existing concrete can be achieved through the modification of the new concrete by latex modification. But, no test method has been adopted as a standard to measure the bond strength between the concrete used to repair and the substrate being repaired. The performance of old and the new concrete construction defends upon band strength between old and the new concrete. Current adhesion strength measurement method is inaccurate method that ignore effect of stress concentration by shape of specimens. Therefore, this research calculates stress concentration coefficient using finite element analysis and direction tensile strength test (pull-off test). The result shows that the required core depth is 2.5cm. Elastic modulus and overlay thickness do not influence in stress concentration.

The effect of water extract of Poncirus trifoliata fruit (ATFE) on compound 48/80 induced anaphylaxis was studied in the rat. The following results have obtained. 1. Optimal lethal dose of compound 48/80 was 8ug/gm B.W. 2. PTFE was found to exhibit an inhibitory activity on the anaphylaxis induced by compound 48/80. 3. Administration of PTFE 60 min before or 5 min after had a better result than 10 min after anaphylaxis induced by compound 48/80. 4. PTFE also inhibited significantly the serum histamine release in anaphylaxis induced by compound 48/80 in the rat. 5. Administration of PIFE before 30 min decreased PCA reaction induced by anti DNP-IgE and DNP-HSA. This result indicates that poncirus trifoliata suppresses the anaphylaxis induced by compound 48/80 with decreasing the serum histamine release.

The purpose of this study was to remove the excessive air foaming which was produced in mixing the RSLMC(latex-modified concrete with rapid-setting cement) by choosing the best antifoam agent type. A series of RSLMM(latex-modified mortar with rapid-setting cement) experiments were carried out as a basic experiments for RSLMC with the main experimental variables such as antifiamer types (A, B, C, D), antifoamer contents(0, 1, 2, 3%), and latex contents(10, 15%). Air content test and compressive strength tests were carried out to measure the improved properties of RSLMM. SEM analysis, also, was carried to observe the formation of latex film. The results of RSLMM showed that the decrease of 50% air content was obtained by admixturing an antifoam agent by 1%. This made the strength enhanced and the workability be within the purposed. The best properties of compressive strengths was obtained at latex content of 15% and D antifoam agent of 1%. compressive strength increased about 32.6%. The analysis of SEM results no difference in a formation of later film.

This study focused on the investigation of strength development and permeability of LMC(Latex Modified Concrete) and RSLM(Rapid-Setting Cement Latex Modified Concrete) as the latex content cement types and s/c ratio changed. The compressive strength of latex modified concrete decreased slightly and the flexural strength increased quitely at 15% of latex content. This may be due to the flexibility of latex filled in voids and interconnections of hydrated cement and aggregates by a film of latex particles, respectively. The permeability test results showed that the permeability of LMC was considerably lower than that of conventional concrete. Results of chloride permeability test, for RSLMC indicated very low at an early age caused by the early formation of needle-shape ettringites and latex film.

The amount used of aggregates for concrete is increasing rapidly since the mid-1980s in Korea. The natural gravels from river are already displaced with crushed stone, and use of crushed sand as a substitute of natural river sands, also, is getting increased day by day. This paper is presented for mixture of high strength concrete using crushed sands. Mixing design of concretes alee various water-cement ratios(w/c) such as 25%, 40%, 55% and different replacement radio of crushed sands to natural sands such as 0%, 20%, 40%, 60%. As a results, it has been shown that compressive strength of concretes with w/c lower than 40% and 25% is higher than 400 kgf/cm2 and 600 kgf/cm2 respectively.
