  • Vibrio ichthyoenteri is a facultatively anaerobic gram-negative bacterium with straight or slightly curved rod morphology. The bacterium is an etiological agent of bacterial enteritis of Olive flounder Paralichthys olivaceus. Only a handful of studies, using a limited number of isolates, have investigated the phenotypic and genetic characteristics of V. ichthyoenteri. We isolated 40 V. ichthyoenteri strains, identified based on the 16S rRNA gene sequence, from the diseased flounder larvae and investigated the API 20E and ZYM profiles. The isolates exhibited highly divergent phenotypic characteristics regardless of sampling time point and location, and fish age. Essential enzymes produced by V. ichthyoenteri seemed to be alkaline phosphatase, leucine arylamidase, and N-acetyl-${\beta}$-glucosaminidase. This study reveals a much greater enzymatic and biochemical phenotype diversity than has been evident to date. These results suggest that a given population of V. ichthyoenteri could be heterogeneous in terms of its phenotypic characteristics.

  • Grapevine leafroll-associated 3 virus (GLRaV-3) and Grapevine fanleaf virus (GFLV) are important viral diseases of grapevine in the world. In this study, the most reliable woody indicator plants were selected for virus indexing. Two grapevines, LN33 (Couderc 1613x vitis berlandieri) and Vitis riparia Gloire, were selected for CLRaV-3 and CFLV graft indexing, respectively. The specific characteristics of Closterovirus isolated from grapevines cultivated in Korea were identified. filamentous virus-like particles only existed in the phloem parenchyma cell. In particular, the vesiculation of mitochondria was observed. This mitochondrial vesicu-lation was considered to be one of the most reliable cytopathic features of Closterovirus. During observation of GFLV-infected Chenopodium quinoa sections, virus-like particles arranged consistently were found forming several layers in cytoplasm. Moreover, virus-like particles in tubules were observed and were associated with plasmodesmata in cytoplasm. This is the first report on cytopathological characteristics of Closterovirus and Nepovirus identified from grapevines in Korea.

  • The purpose of this study is to establish PM-10 management manual for developing large scale sites by assessing the status of PM-10 reduction at ongoing large scale development sites. After analyzing the meteorological conditions and air quality characteristics of Sihwa MTV development site, ISCST3 (Industrial Source Complex Short Term Model 3) was implemented to predict PM-10 generation. The outcomes of ISCST3 modelling were utilized for verification of site survey data. As a result of applying air pollution modeling, the diffusion rate of PM-10 decreases according as the wind speed decreases. And the emission rate of PM-10 increase is linear to the concentration of PM-10. The reduction target of PM-10 can be derived quantitatively from the difference between the forecasted emission rate and the permissible emission limit of PM-10. The assessment of PM-10 characteristics which is deduced from ISCST3 and site survey can be practically applied to accomplish environmentally acceptable air quality manual for large scale development sites.

  • The high-pressure hydrogen valve is intended to supply hydrogen charged at high pressure in the hydrogen tank to the fuel cell stack, which decompresses high-pressure hydrogen gas to low pressure and primarily limits the excessive flow. It consists of a pilot valve, a main valve, and a excessive flow valve to operate in a wide pressure range from 2 to 70 MPa of charging pressure. The opening characteristics of the valve were confirmed by computation fluid dynamics applying the moving grid technique. The behavior of the valve was predicted by predicting the force acting on the valve over time. In addition, the difference in behavior according to supply pressure was compared.

  • In order to revitalize rural areas fundamentally through multifunctional utilization of their resources, it should be necessary to prepare the rational development plan to the areal characteristics and conditions, and the first priority of its planning works should be given to spatial planning. The space syntax method, a powerful objective and quantitative analysis tool on the relationship between social and spatial characteristics, was introduced in this study. Five Comprehensive Rural Clustered Villages Development Areas in the Jeonnam-province were selected as case study areas, of which total area's and included villages' spatial variables were measured and analyzed. Rural villages analyzed in this study have the spatial structure badly systematized and much complicated, which results from low integration and deep spatial depth of them. And, by virtue of relatively many axial lines, there should be few differences between villages in terms of local integration, connectivity and control, while being significant difference in terms of global integration showing the whole areal characteristics. Intelligibility, the correlation coefficient between connectivity(local variable) and integration(global one) is low, which means that the spatial structure of the study areas is difficult for visitors to understand the area or village well. Spatial configuration analysis results in the case study areas showed that each development area has a unique spatial structure and is differentiated in terms of not only local spatial variables but also global spatial variables. Therefore, global and local characteristics should be considered in spatial analysis of development areas.

  • Objectives : This study was aimed at exploring career-related characteristics of premedical students in Korean Medicine college and those relationships with career development readiness and vocational value. Methods : A total of 140 premedical students participated in the survey. The questionnaire consisted of demographic characteristics and career-related characteristics such as motive for career choice, specialty preference after college graduation, and school life adaptation. Also they responded in the web-survey of career development readiness inventory and vocational value inventory developed by Korea Research Institute for Vocational Education & Training. Eight items of motive for career choice were collected from the pilot study from 70 premedical students. Results : 'Job stability' was the top motive for career choice(25.5%). The average college life adaptation score was relatively low(13.7) : higher in male(14.3) and the early career decision group(14.2) than female (12.9) and late decision group(12.9), which was statistically significant(p=0.019 and p=0.036, respectively) in the subgroup analyses. The result of career development readiness inventory showed that 'self-knowledge' (79.3) and 'confidence on career decision' (78.6) were the two highest, which is similar to the result of the vocational value inventory ('fulfilling abilities' and 'self-improvement'). More characteristics were also described. Conclusions : The results showed that Korean Medicine premedical students have high vocational identity. This study suggested that more specified studies for identifying career-related characteristics for Korean Medical students should be conducted in order to design systematic and professional medical education programs.

  • This study aimed to propose a fashion design development method using the external and internal characteristics of the flower and bird paintings in traditional Korean folk paintings. As a research method, external and internal characteristics of folk paintings were examined through previous studies and literature research, and folk painting patterns were developed into digital textile designs. Five 3D digital fashion designs were proposed using the CLO 3D program. The external characteristics of folk paintings were as follows: simplification and planarization of object representation, diversification of viewpoints, ignorance of perspective and symmetrical enumeration, strong colors and contrast effects, and the simultaneous representation of time. The internal characteristics of folk paintings were as follows: symbolic meaning, the beauty of free humor, modest aesthetics, complexity of reality and fantasy, and desire of shamanism. The results are as follows. Firstly, the flower and bird painting was a decorative painting style that emphasized decorative beauty and was suitable for developing fashion designs with Korean originality because of the symbolic and internal meanings. Simple layouts and bold free-spirited representations were effective ways to fill the screen with objects and gave the pattern a decorative effect. Secondly, developing a virtual clothing prototype based on digital design method using the external and internal characteristics of folk paintings and producing realistic fashion designs suggest the integrated use of science and technology, embodying modern fashion through the combination of digital fashion content and traditional cultural content. Thirdly, as a result of the development of 3D digital fashion designs, an eco-friendly and sustainable fashion design methods with virtual clothing can suggest a design development method that saves time and cost in the fashion design process while considering the environment.
