  • A practical approach for the assessment of system reliability-based safety and load carring capacity under vehicle traffics is proposed for the realistic evaluation of safety and rating of cable-stayed bridges. A partial event tree analysis model incorporating major critical failure paths is suggested as a practical tool for the system reliability analysis and system reliability-based capacity rating. The proposed approach for the system reliability analysis and system reliability-based rating is applied to the safety assessment of the Jindo Bridge which is one of two existing cable-stayed bridges in Korea. The results of analyses at the system level based on the system reliability are compared with those at the element level.

  • The background of this paper is the HVDC concept design of Jeju HVDC #2, which will be operated at 2011. The concept design is the first step of HVDC design procedures and the contents handled in this procedure are operation conditions, short circuit ratios(SCR) and interactions between AC network and HVDC. The operating conditions are based on the reliability of HVDC and AC network, SCR is related to HVDC stability and overvoltage and the interaction is between HVDC and other AC equipments, that are FACTS, generator and HVDC. The results of this paper are a keystone of HVDC #2 design.

  • In these days, it is serious problem to inappropriately eliminate in the home. There are many reasons why a pet might eliminate in the home. A ten-month-old, female, Jindo dog with a history of inappropriate elimination was presented to the Animal Behavior Clinic at the College of Veterinary Medicine, Gyeongsang National University. This problem was diagnosed by submissive and excitement urination based on the questionnaires and interviews on the dog with the owner. Behavioral modifications including ignorance and counterconditioning were recommended to improve the clinical signs. After two weeks following the initial consultation, submissive and excitement urination of the dog was alleviated, and after four months, it resolved completely, to the owner's satisfaction.

  • One of the main objectives of the study is to propose a practical but realistic limit state model considering combined effect of axial and bending load for reliability analysis and safety assessment of cable-stayed bridge under vehicle traffic loads. This paper is intended to propose a new approach for the evaluation of reserved load carrying capacity of cable-stayed bridge under vehicle traffic loads in terms of equivalent strength, which may be defined as a bridge strength corresponding to the reliability index of the bridge. This can be derived from an inverse process based on the concept of FOSM form of reliability index. AFOSM and IST methods are used for the reliability analysis of the proposed models. The proposed reliability model and methods are applied to the safety assessment of Jindo Bridge which is one of major two cable-stayed bridges in Korea.

  • According to the research of the cultivation result on the spot farmers for 5 years in order to investigate its cultivation conditions and problems of Lycium chinense Mill, the development of the variety with early mature, pest tolerance, and high yielding is urgent and it is call for the development of rooted cutting cultivation by testing of bed soil, growth regulator and cutting times. The development of cultivation method with planting year, planting density, supplementary period and amounts of supplementary of Lycium chinense Mill planted in growing field are required and for the disease and the effective control of disease and insect pest resistance is needed by auxotrophic fertilizing and organic agricultural method, met by agricultural chemicals.

  • A squillid stomatopod, Oratosquilla fabricii, collected from Jindo Island, is reported for the first time in Korea. The family Squillidae differs from other families by the presence of more than four intermediate denticles of telson. This species is distinguished from O. oratoria, another Oratosquilla species recorded in Korea, by the presence of an armed submedian carinae on the fourth abdominal somite and dark patches on the second abdominal somite. In the present study, detailed descriptions and illustrations of O. fabricii are provided. A key to the species of Korean Oratosquilla species is also presented. With this new record, the number of stomatopod species in the Korean fauna has increased to 16.

  • An anisogammarid amphipod, Eogammarus possjeticus (Tzvetkova, 1967), is newly recorded from Jindo Island, Korea, with a detailed description and illustrations. The species belonging to the genus Eogammarus are sharing several plesiomorphic characteristics, so they are similar to each other. However, Eogammarus possjeticus can be discriminated from congeners by the following characters combined: appendages are not fossorial, setations of antennae are weak, and the number and position of robust setae on pleonal epimera, urosomes, and telson are different from its congeners. This is the first record of the genus Eogammarus Birstein, 1933 from Korean waters.
