  • 기존 유해성 적조의 발생해역에 대한 공간결정 연구는 미비하였으며, 적조발생지와 소멸지에 대한 공간을 정확하게 판단하기 어려웠다. 따라서 좀 더 객관적이며, 과학적인 방법으로서 적조의 발생과 이동에 따른 시 공간적인 방법으로의 분석 필요성이 대두 되고 있다. 본 연구에서는 매년 발생되는 유해성 적조 발생지에 대한 공간을 파악하기위해 수치지형도를 이용한 GSIS기법을 적용 해안선을 추출하였으며, 수년간 발생된 적조발생 자료를 근거로 발생지의 공간위치를 결정하여 분석한 결과 연구지 중 여자만 일대에서는 적조의 발생이 거의 없었음을 알 수 있었고 남해 돌산도와 남해도 앵강만 해역일대에서 최고의 발생빈도를 나타냄을 알 수 있었다. 이를 근거로 매년 반복적으로 발생되는 해역에 대한 적조의 분포상황을 시공간적으로 판단하여 이동경로 해역의 예측과 피해의 사전예방이 가능하리라 판단된다.

  • 연구목적: 본 연구에서는 국내 자동차 관련 화재발생 현황 및 위험성을 평가하고 초기 소화기구의 사용에 따른 피해저감 효과에 대해 평가하였다. 연구방법: 국내 자동차 화재의 발생 빈도에 대한 위험성 분석과 화재발생시 자동차에 비치되어 있는 소화기를 사용하여 초기 소화에 적용한 사용에 따른 인적 및 재산피해를 분석하였다. 연구결과: 국내 자동차 화재 발생에 따른 건당피해액은 연평균 증감률이 4.74%이고 매년 증가하는 것으로 나타났다. 자동차 화재현황 중 승용자동차에서 발생한 인명피해를 연도별 화재발생 건당 인명피해로 분석한 결과, 화재발생 100건당 재산피해액은 424.65만원에서 473.06만원으로 과거 5년간(2012년~2016년) 지속적으로 증가하는 추세를 보이고 있다. 결론: 승용자동차 화재시 소화기를 사용한 경우에는 화재발생 1건당 평균 재산피해액은 약 307.5만으로 산정되어 초기 자동차 화재에 차내에 비치된 소화기를 사용한 초기소화의 중요성과 필요성이 요구된다.

  • Erwinia pyrifoliae, which causes black shoot blight in apple and pear trees, was first identified in Korea in 1995. Extensive measures are typically used to control the disease by eradicating trees in diagnosed orchards, owing to the detrimental impact of the disease on apple and pear production. However, despite governmental efforts, the disease has continuously spread. In this study, we analyzed the current status of the black shoot blight occurrence in apple and pear orchards between 1995 to 2022. Our findings reveal that over the past 28 years, black shoot blight has occurred in 26 cities and districts across five Korean provinces. The affected regions are predominantly concentrated in the northern part of Korea, including the Gangwon and Gyeonggi provinces. Furthermore, black shoot blight has gradually expanded to the northern provincial regions of Chungbuk, Chungnam, and Gyeongbuk, which are centrally situated in Korea. Furthermore, the occurrence pattern of black shoot blight differed between apple and pear orchards; in apple orchards, black shoot blight occurred consistently each year, with a sudden increase in cases in 2020; however, in pear orchards, it has considerably decreased since 2007. To the best of our knowledge, this is the first comprehensive report on the occurrence of black shoot blight in apple and pear trees in 28 years, and the results will provide valuable insights for future disease management strategies.

  • 최근 도시지역의 빈집 발생은 주목할 만한 사회문제이다. 물리적 쇠퇴 현상 중 하나인 빈집 발생은 인구감소, 상권침체 등 다양한 사회·경제적 쇠퇴를 가속화 시킨다. 빈집은 지역적 특성 및 공간적 영향력이 존재하며, 정확한 빈집 실태를 파악하기 위해서는 국지적으로 접근할 필요성이 있다. 이에 본 연구에서는 전역적 Moran's I와 지리가중회귀모델(GWR)을 활용하여 도시쇠퇴가 빈집 발생에 미치는 영향을 지역별로 살펴보았다. 분석 결과, 부산광역시 읍면동별 빈집 발생은 공간적 자기상관성 및 이질성이 존재하였다. 또한 각각의 도시쇠퇴 변수들이 빈집 발생에 미치는 영향이 차이가 있으며, 동일한 도시쇠퇴 변수라도 지역에 따라 빈집 발생에 미치는 영향력이 다르게 나타났다. 이에 GWR모델을 활용하여 지역별로 차별화된 계수 값을 해석하고 빈집 발생을 유형화 한다면 보다 효율적인 빈집 관리 방안을 제시할 수 있을 것으로 보여진다.

  • Periodic lateralized epileptiform discharges (PLEDs) had been debated whether it is ictal or non-ictal phenomenon. As most of PLEDs occur in patients with acute structural lesions, some epileptologists prefer PLEDS as a non-ictal phenomenon, rather an obscure epiphenomenon of etiological diseases. But, almost half of the patients with PLEDs do not have acute structural lesions in the brain and metabolic disorders or old CNS lesions may cause PLEDs and even more, no brain lesion was identified in some patients. There are many data supporting PLEDs as ictal phenomena. Occurrence of PLEDs usually accompanied by decreased mentality and is improved as PLEDs disappeared. Current SPECT study showed marked hyperperfusion in the lesion side of PLEDs, that is striking evidence of PLEDs as ictal phenomena. Also careful review of EEG with PLEDs revealed it is a dynamic process rather than a static state. Despite of these evidences, as PLEDs are an end-stage of animal status epilepticus models, it may be a transition of ictal to interictal state.

  • Cancer of the uterine cervix is a worldwide menace taking innumerable womens' lives. The literature is vast and a large number of studies have been conducted in this field. Analyses have shown significant differences exist in terms of screening and HPV testing facilities among high income and low to middle income countries. In addition, acute lack of awareness and knowledge among the concerned population is particularly noted in rural areas of the low income countries. A detailed review of Indian case studies revealed that early age of marriage and childbirth, multiparity, poor personal hygiene and low socio-economic status among others are the principal risk factors for this disease. This review concludes that a two pronged strategy involving strong government and NGO action is necessary to minimize the occurrence of cervical cancer especially in low and medium income countries.

  • The purpose of this study was to ascertain the breeding efficiency in Thoroughbred mare. A total of 106 mares were investigated for the status of follicle (462 cases), ovulation (179 cases) and pregnancy (346 cases). Of total examination, 46.8% was follicle measure to determine breeding time, and mating rate per cases examined was 39.9%. There was no correlation between reproductive results and size of follicles or endometrial edema or degrees of teasing alone. 143 cases were ovulated among 179 cases which were performed ovulation examination, and ovulation rate and fertilization rate per mating times were 79.9% and 39.0%, respectively. The use of hCG(human chorionic gonadotropin), to facilitate ovulation, presented to increase occurrence of double ovulations and twin fertilizations In conclusion, though more examination to estimate the optimal breeding time and higher mating rate was performed, fertilization rate per mating times was lower and then reproductive efficiency also became decreased. Therefore, it seemed that accurate examination of reproductive tracks, appropriate teasing programme and hCG administration before ovulation were of help to improve ovulation rate and fertilization rate.

  • Recently, it is getting more and more important ensuring the integrity for the equipment degradation according to the increase of nuclear power plant operating period. In many equipment of the nuclear power plant, snubbers mainly installed in reactor coolant pumps, steam generators and piping protected the equipment and piping from the occurrence of transient dynamic loads such as the earthquake, thermal load during the plant operation. This report describes the function, regulation, inspection requirements and management status of the snubbers installed in domestic nuclear power plants.

  • Cortisol levels in plasma are known to be as an indication of reproductive and adrenal status of an animal. In this study it has been examined in relation to the oestrus induction by Progesterone oestrogen therapy in 3rd and 4th parity anoestrus animals. Cortisol was found higher in treated animals and levels raised within 6-12 hrs. after hormone therapy followed by elevation in glucose levels and depletion of total serum proteins. It shows the association of induction, occurrence and expression of oestrus with energy demanding metabolic stress in buffaloes.
