  • 기후변화로 인한 수문학적 변동은 지속가능한 수자원 관리를 위해 중요한 인자로 고려되고 있다. 특히, 가뭄 등 기상재해는 자연재해 차원을 넘어서 사회적 갈등으로 발전할 여지가 크며 특히 수자원 배분은 환경, 경제를 뛰어넘은 생존의 문제로 발전하고 있다. 따라서 본 연구는 기후변화가 가져올 가뭄 등 재해관리를 위한 의사지원체계 구축하고 다양한 기후변화 시나리오에 대응할 수 있는 탄력성 있는 수자원전문가시스템의 개발을 통해 이상기후 및 가뭄대비 물분쟁에 대한 합리적 대안을 제시하고자 한다. 본 연구에서는 섬진댐의 상황을 모델로 하고 있다. 섬진강 유역은 섬진강댐의 건설당시 발 빠른 이주대책의 불이행으로 수몰지역 내에 초기 정착민들이 계속 거주하게 되어 댐 제원을 충분히 활용하지 못하고 있어 효과적인 치수사업에 어려움을 겪어오다가 공사간의 협력을 통해 치수능력증대사업을 추진하여 저수지의 저류량을 증가시키고자 섬진강댐 재개발 사업을 추진한 지역이다. 하지만, 유역내의 이상기후로 인한 수문학적인 변동과 가뭄으로 인한 물관련 당사자간의 용수확보분쟁의 소지가 있어 물관리를 위한 수자원전문가시스템의 개발이 시급한 실정인 지역이기도 하다. 대상지역 수자원전문가시스템의 개발을 목표로 HSPF(Hydrologic Simulation Program with FORTRAN)을 이용하여 기후변화로 인한 수문학적 변동성을 파악하였다. 그리고 수자원 전문가 모델로서 외국에서 사용되고 있는 SUPER, HEC-ResSim, RiverWare, MODSIM, WRAP, PowerSim, 그리고 STELLA의 장 단점 등 특성을 분석하여 국내에 적합한 수자원전문가시스템 갖추어야할 기능 및 구성을 분석하였다. 연구 결과 국내실정에 필요한 모델은 공영시각모형(Shared Vision Model)으로서 그 장점은 첫째, 수자원의 관리나 물분쟁시 반드시 필요한 유역의 물리적인 인자와 수역관리에 필요한 수문인자, 그리고 물분쟁의 소지가 있는 의문사항이나 문제점의 해결책을 위한 실마리를 제공할수 있다. 둘째, 물관련 이해당사자들이 직접 참여하여 모형을 평가하고 서로간의 이해관계를 위한 충돌이 발생했을 때 문제해결을 위한 대안을 제시할 수 있는 정보를 제공할 수 있다. 셋째, 물배분의 원칙에 따른 한쪽으로 편중된 대안이 제시되었을 경우에 공동으로 대안에 대한 평가를 통하여 평등한 물배분을 가능하게 한다. 넷째, 시민단체나 환경단체, 그리고 기관책임자들이 공동으로 모형의 형성과정을 지켜본 후 논의할 수 있어 이상적인 모형을 만들 수 있는 장점이 있다.

  • An aim of this study was to evaluate an effect of misinterpretation of pregnancy related cellular changes on the postpartum regression rate of abnormal cervical smears in pregnancy. A series of 265 cases with abnormal cervical smears in pregnancy were selected from a database of cervical smear results. The selected cases were classified as regression, persistence, and progression based on the results of postpartum cervical smears and histology. Of the selected cases, 162 cases were classified as regression and the postpartum regression rate was 61.1% (162/265). We reviewed abnormal cervical smears in pregnancy these cases. The primary cytologic diagnoses of these cases were ASCUS (118 cases), AGUS (2 cases), ASCUS/AGUS (1 case), LSIL (25 cases), LSIL R/O HSIL (2 cases), and HSIL (14 cases). With information of the pregnacy, we identified decidual cells in 24 cases, but cells identified by the Arias-Stella reaction and trophoblasts were not found. Sixteen cases out of 162 cases were reclassified as a pregnancy related change rather than an abnormal. Desidual cells were considered as ASCUS in 15 cases and as LSIL in one case. The revised postpartum regression rate was 55.5%(147/265) and was lower than the original. Consequently, misinterpretation of the pregnancy related cellular changes has an effect on a rise of the postpartum regression rate of the abnormal cervical smear in pregnancy. Pathologists may diagnose pregnancy related cellular changes as abnormal findings if they do not have information regarding the pregnancy. Therefore, clinical information of pregnancy and knowledge about the pregnancy related cellular changes are essential to prevent misinterpretation.

  • The purpose of this thesis is to study about destructive method in late twentieth Century Paintings. To do this we will consider the examples of Frank Stella and Anselm Kiefer's expressive methods. And this thesis is designed to investigate the change of the two Modes. The centering change is in the destructive manner of them, and they are traced systematically. In these chapters we will study the procedure of the destruction and specification of the Modes; the subject which contains the special element, the relation between it and the artist's willful meaning, morphological specification, symbol system formative language, subject, material and coloring way. etc. The origin of the methodology is systematically studied and the procedures of the content applicated are considered. In the special characteristics of the methodology, the special feactures it contains will be considered. The basis of the deconstructive idea from Nietsche, Derrida, Saussire, Andrew Benjamin and others will be applied to understand the two Modes of artistic methodology, and whether or not they can be tools of explaining the methodology of our time is distinguished. Next, the methodologically founded contents and concepts from Chapter#2 are related and intertwined together. The outer destructive aspect and inner destructive specification are centrally uncovered by the Interpretation. The resulting background of the Mode, the factor of destruction and central concept, along with the works, applied ideas, and pre-scholar's writings, are conjoined and explained. The characteristics of S Mode are revealed as being similar to those of Vandalic Destruction and Baroque formalistic Style, while K Mode is closely related to Iconoclastic Destruction and Neoclassical Antiformal Style.

  • The global evolution of antibiotic resistance has threatened the efficacy of available treatment options with ravaging impacts observed in developing countries. As a result, investigations into the prevalence of antibiotic resistance and the role of plasmids are crucial. In this study, we investigated the presence and distribution of blaTEM and gyrA genes, plasmid profiles, and the antimicrobial susceptibility pattern of Salmonella strains isolated from raw meat and stool sources across Niger State, Nigeria. Ninety-eight samples, comprising 72 raw meat and 26 stool samples, were screened for Salmonella spp. The antimicrobial susceptibility of Salmonella isolates to 10 commonly used antimicrobial agents was determined using the KirbyBauer disc diffusion method. Isolates were further analyzed for plasmids, in addition to PCR amplification of beta-lactamase (blaTEM) and gyrA genes. A total of 31 Salmonella spp. were isolated, with 22 from raw meat (70.97%) and 9 from stool (29.03%). Salmonella spp. with multiple resistance patterns to ceftazidime, cefuroxime, ceftriaxone, erythromycin, ampicillin, cloxacillin, and gentamicin were detected. Ofloxacin and ciprofloxacin were found to be the most effective among the antibiotics tested, with 67.7% and 93.5% susceptible isolates, respectively. Nine (29.03%) isolates harbored plasmids with molecular sizes ranging between 6557 bp and 23137 bp. PCR amplification of gyrA was detected in 1 (3.23%) of the 31 isolates while 28 isolates (90.32%) were positive for blaTEM. This study shows the incidence of antibiotic resistance in Salmonella isolates and the possible role of plasmids; it also highlights the prevalence of ampicillin resistance in this local population.

  • Background: Workplace bulling is a pervasive phenomenon with negative consequences for the health of victims and the productivity of organizations. The aim of this study was to measure the prevalence and forms of workplace bullying among employees working at the public health-care sector of Cyprus using the Greek version of Leymann Inventory of Psychological Terror (LIPT) instrument. Methods: A translation process was followed from the French to the Greek version of LIPT questionnaire. Test-retest reliability expressed by Pearson's correlation coefficient was 0.98 indicating excellent reproducibility. Internal consistency reliability assessed by Cronbach ${\alpha}$ coefficient was 0.87 suggesting high reliability. LIPT instrument was distributed among 403 employees working at the primary health-care setting and at the largest public hospital of Cyprus with response rate of 73.4%. Results: Women comprised the majority of participants (71.4%). Mean age was 43.3 years. Prevalence of workplace bulling according to Leymann's definition was 5.9%. Most common forms of bullying were "Being continuously interrupted" (17.2%) and "continuously being given new work assignments" (13.5%). Women were significantly more often exposed to at least one mobbing behavior than men within the previous year (49% vs. 35.7%, p = 0.038), whereas nurses were significantly exposed to at least one mobbing behavior as compared to physicians (53.3% vs. 31.4%, p = 0.004). Conclusion: This was the first study that examined the prevalence of workplace bullying in the public health-care sector by elaborating the Greek version of LIPT instrument. Results showed that workplace bullying is a common and complex phenomenon among health-care organizations.

  • Background: The current study evaluated the hospital utilization and characteristics of patients who received health care services for acute cerebral infarction outside their own residential area. Methods: Using the 2014 national patient survey data, information on 2,982 patients diagnosed with acute cerebral infarction through emergency department were retrieved for the analyses. Multiple logistic regression was performed to investigate the characteristics associated with using hospitals outside residential area among patients diagnosed with acute cerebral infarction. Results: Fifteen point nine percent of patients admitted for acute cerebral infarction utilized hospitals outside their residential area. Patients residing in a province were 7.7 times more likely to utilize hospitals located outside their residential areas compared to those living in Seoul metropolitan city. Patients living in Gangwon and Jeolla were 0.26 times and 0.48 times more likely to go to hospitals in different geographical areas. Also, patients within the age group of 80 years and over were 0.65 times less likely to be admitted to hospitals outside their residential area compared to those in their 40s-50s. Conclusion: The use of hospitals outside patient's residential area is shown to be substantial, given that the acute cerebral infarction requires immediate recognition and treatment. The findings on the geographical differences in the hospital utilization suggest further investigation.

  • This autobiographical narrative interview study aims at exploring how A, one Korean 82-year-old female farmer strived vigorously to learn by herself and to teach her children (4 boys and 3 girls) despite the fact that she was not afford to pay tuitions on time. From 40 times of interview-data three major findings emerged: (1) A learned how to read Korean Japanese and Chinese characters and how to calculate at a free-of-charge teaching center although her father didn't approve of her learning; (2) A tried very hard to earn money inside and outside home to support her children's education, organizing many mutual fraternity meetings to seek mutual financial support, selling mostly farm products as well as farming almost all day and everyday; (3) Although it was so hard to educate three daughters, A was proud of the fact that she was able to put her second daughter to a high school with a promise to pay her tuition later. Some implications of the findings are added.

  • This study was carried out to examine the awareness and use of social media tools by library and information professionals (LIPs) in selected academic libraries in South-west, Nigeria and the challenges they face in the use of social media technologies. Descriptive survey was adopted for this study. The population of the study comprised 217 library and information professionals from 10 selected academic libraries in south-west, Nigeria. A total enumeration technique was used to cover all the library and information professionals, 136 respondents filled and returned the questionnaire, given a response rate of 62.7%. The questionnaire was used as instrument for data collection. Descriptive statistics was used to analyze the data collected. The findings show that majority of LIPs possessed a high level of awareness in the use of social media tools. The study also revealed that social network tools were highly used by LIPs in the academic libraries studied and the types of social media used by LIPs was also revealed. The major challenges faced in the use of social media include inadequate power supply, lack of Internet access and time constraints. The paper recommended that to enhance the use of social media by LIPs, there is need for constant awareness of the importance of social media tools to LIPs and libraries in effective service delivery, LIPs should be ready to learn, unlearn and be learned in the use of social media and university libraries should provide enabling environment such as internet connectivity, power supply and policy to guide LIPs in social media usage.
