This study was carried out to investigated the distribution and characteristics of Vibrio spp. isolated from fish and shellfish, seawater and brackish water samples collected from Pohang, Uljin, Yeongduk and Gyeongju in Gyeongbuk Province from April 2000 to October 2000. Total 155 strains of genus Vibrio were isolated from 439 collected samples, and numbers of isolated strains of V. parahaemolyticus and V. vulnificus were 140 and 15, respectively. The isolation rate from the samples collected in Pohang was the highest as 41.5% (76 strains), and wat the highest as 71.4% (30 strains) in brackish water, and was the highest as 55.7% (34 strains) in August. And the optimal pH, temperature, and NaCl concentration for growth of V. parahaemolyticus and V. cholerae were 8.0, 3$0^{\circ}C$ and 2.0％, respectively. In a resistance test for environmental factors, heat and cold resistants of V. parahaemolyticus were higher than those of V. vulnificus, withstanding for 15 minutes at 6$0^{\circ}C$ and 6 days at -18$^{\circ}C$. The pH range for existence of V. parahaemolyticus and V. vulnificus were 4.5~l1.0 and 4.5~10.0, showing the similar resistance to pH. V. parahaemolyticus and V. vulnificus could grow in media containing up to 10.0% and 7.0% NaCl, respectively, Salt-tolerance of V. parahaemolyticus was higher than that of V. vulnificus. In an antibiotics sensitivity test against 16 strains of V. parahaemolyticus, twelve strains were resistant to ampicillin, eight strains were resistant to cephalothin. one strain was resistant to streptomycin, and one strain was resistant to ticarcillin.

Members of the genus Brucella are facultative intracellular bacteria and cause brucellosis, a chronic disease in humans and abortion in animals. In this study, we tested sera for brucellosis of 15 Hanwoo farms in the western part of Gyeong-buk province, resulting 5 farms were brucellosis positive in 2008. We collected blood from 277 heads in the brucellosis positive 5 farms, and performed serological diagnosis, brucella positive cattle which had shown higher than 200 antibody titer in tube agglutination test were slaughtered, supramammary lymph nodes were collected, and Brucella spp. wild type isolation and identification were performed. From these results, 15 of Brucella spp. wild type strains were isolated and all strains were identified as B. abortus biotype 1 by biological and molecular analysis. In the antimicrobial susceptibility test, all 15 strains had a similar susceptibility and resistance pattern. This study may be useful for bacteriological and epidemiological understanding of cattle brucellosis in Korea.

The purpose of the study was to investigate the effects of the characteristics of dietitians, the characteristics of school food services, equipment ratio of HACCP facility/equipment and perception of barriers to HACCP implementation on external and internal audit of food safety/sanitation management performance in school food service. An e-mail survey was conducted with 144 dietitians in Gyeongbuk Province. A response rate was 57.6% (N = 83) and data was analyzed using SPSS windows (ver. 12.0). Dietitian perceived facilities/equipment-related and stakeholder-related as the big barriers in implementing a HACCP system. Total scores of sanitation/safety management performance for external and internal audit were similar at 92 and 91 out of 100, respectively. 'Facilities/equipment' and 'HACCP system' categories in both external and internal audit were rated the lowest. As dietitian perceived facilities/equipment-related (p < 0.001) and stakeholder-related (p < 0.05) barriers to HACCP implementation were greater, the scores of the external and internal audits were significantly lower. As dietitian perceived barriers for all categories were greater, the scores of internal audits were significantly lower (p <0.05). As a result of multiple regression analyses, the scores of the external audit was positively associated with career as a school food service dietitian, but was negatively associated with barriers related to facility/equipment, while the scores of the internal audit was negatively associated with barriers related to facility/equipment and employees. This study suggests that supporting programs on securing the facilities/equipment and employee training are needed for successful HACCP implementation in school food service.

Northern corn leaf blight caused by Exserohilum turcicum Pass is considered the most important disease infecting corn (Zea mays L.) in the Peoples' Republic of Korea (North Korea). It contributes to the food shortage in North Korea. The objectives of the current research were to study resistance expression and responses of corn crosses made between ten hybrids from North Korea and inbreeding lines ($S_{3-4}$ stage) from the Republic of Korea (South Korea). The experiments were conducted in six trials with a total of 184 crosses including two commercial hybrids in each trial. The trials were conducted at two locations in North Korea (Mirim and Eunsan) and one location in South Korea (Gunwi) under natural infestation of E. turcicum. Host plant responses were rated on a scale of 1 (highly tolerant) to 9 (highly susceptible). A total of 111 crosses (62.4%) showed significant tolerant or susceptible response variations among three locations; 42 crosses (22.8%) at two locations and 69 crosses (39.0%) at one location, respectively. At least 8 crosses of high level of tolerance and 12 crosses of high level of susceptibility showed significantly different biotic responses (P = 0.05). The results of the current study and historical reviews of E. turcicum epidemics in both North and South Korea suggest that breeding of tolerance with quantitatively inherited genes should be carried out for a sustainable corn production in North Korea.

As creative city is increasingly considered as a paradigm of urban development, it was explored that some of major concepts consisting of creative city such as creativity, creative class and creative industry have an implication. Those concepts reveal a diverse meaning rather than universal one in the application depending on regions and countries across the world. This study tried to grasp the meaning of creative city in the northern region of Gyeongbook where the concept itself was not apparently distinctive. The result is that the inherent meaning of creative city was expanded to culture and athletic fields, though it was originated from taking advantage of nature, agricultural products in the region, and cultural and historical based tourism. On the other hand, the role of regional authority was examined to explore how the concept of creative city is realized in practice. There are some differences among the local authorities in the aspect of leadership. network system within the region, and social network with outside.

We studied the seroprevalence of four respiratory pathogens in Korean swine farms located in Chungnam, Chungbuk, Gyeongnam and Gyeongbuk provinces during the period of spring of 2007 to winter of 2008. Serological tests were performed using commercial ELISA kits. A total of 530 serum samples were tested for the antibodies against porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV2), Mycoplasma hyopneumoniae (M. hyo) and Actinobacillus pleuropneumoniae (APP). Seroprevalence for four respiratory pathogens were estimated by ELISA-positive rates of the submitted samples. The overall seropositive rates of PRRSV, APP, M. hyo and PCV2 were 32.6%, 10.6%, 38.4% and 88.5%, respectively. By production stage, the seropositive rate for PRRSV was highest in nursery pig populations (46.2%). In contrast, the highest seropositive rates of APP and M. hyo were observed in sow and growing pigs. However, the seroprevalence of PCV2 was ranged from 85.7% to 89.6%, showing no significant difference among the production stages. In the seroprevalence by season, PRRSV, APP and M. hyo infections revealed typical seasonal patterns that the peaks of the seropositive rates were observed between early winter and late spring. In case of PCV2, no particular seasonal patterns were noticed. The pig herds in Gyeongbuk province where PMWS was endemic during the period of survey showed the highest seropositive rates for PRRSV (44.6%), M. hyo (47.5%), and PCV2 (92.7%). Seropositive rates for APP of four provinces were approximately 10%. These results might be valuable for control and prevention of the respiratory diseases and helpful to define strategies related to vaccine applications.

The characteristics of time changes in air temperature, DI (discomfort index) and WBGT (wet-bulb globe temperature) were investigated for inland city (daegu) and coastal city (pohang) of Gyeongbuk Province during the 2018 consecutive heat wave season. The time when the temperature dropped below 33℃ was around 19h in both regions. As such, the two regions were similar with respect to the time up to which the heatwave warning levels continued. However, the discomfort index (DI) was higher than 27 in Pohang. Most people feel unpleasant when an discomfort index of 27 or higher appears. The results indicated that Korea's night-time thermal environment during the summers is particularly poor in the southern coastal areas. WBGT began at 09:00 and lasted until 21:00, with a score of 31 or higher; this score, in principle, corresponded with the duration of outdoor activity in both regions. Therefore, it was found that outdoor work was at a level where all day long had to be stopped in both areas during the heat wave. Although time changes in temperature and WBGT were similar in both regions, Discomfort Index (DI) differed significantly. The difference refers to the fact that Pohang is strongly affected by the high heat capacity effect and the supply of water vapor from the sea.

In this study, nurses above the age of 20 years and working in General Hospitals located in the Gyeongbuk province were enrolled as participant. A survey was conducted to identify the relationship between types of health-eating, level of occupational stress, and degree of quality of life. An effective sample size of 120 was determined, and it was validated as a feasible count to perform the analysis by applying the PLS-SEM. We hypothesized that the physiological and psychological occupational stress levels vary according to functional, mental, and trendy types of health-eating lives and impact the degree of quality of life. This was evaluated using structural models, employing the bootstrapping method using the Smart PLS 3.0. Our results indicate that in the relationship between health-eating types and quality of life, the higher the functional health-eating type, the higher the quality of life. The association between job stress and quality of life showed that the higher the psychological work stress, the more negative the quality of life. Examining the association between the type of healthy eating and the quality of life revealed that the higher the functional health-eating type, the higher the quality of life. As a result of verifying the moderating effect of the difference in working period (less than 3 years/more than 3 years), it was found that the shorter the working period (less than 3 years), the higher the psychological stress.

This study investigates how much building area among total building area concentrates on urban region in a local government region and then, I applies 'The Index of Building Concentration in Urban Area' for the first time in a study. The finding shows that Cities' Index is higher than counties', and also shows that a lower index is associated with a higher rate of older adult population, and is also associated with higher general budget expenditure by the local government based on the index of Building Concentration in Urban Area in Gyeongbuk Province. This study provides evidence that the Index of Building Concentration in Urban Area can be utilized in measuring shrinkage level, effectiveness of municipal finance, and in establishing shrinkage city/county planning by basic data.

The purpose of this study is to analyze empirically the effects of changes in policies of the construction industry on the entry and exit in the construction industry and to present the direction of changes in construction industry policies based on the analysis results. The purpose of this study is also to present by analyzing the factors influencing the increase and decrease of builders in the actual construction market. The results of the survey indicate that for general contractors in Daegu and Gyeongbuk, which are mostly small and medium-sized construction companies, the strengthening of registration standards (capital, technicians, etc.) has a significant impact on market entry and exit. However, on the other hand, many of the construction policies implemented to eliminate unqualified contractors in the construction market have had the effect of increasing the number of unqualified contractors. This suggests that construction policies in the construction cycle have not achieved their objectives.
