Objectives: This case study aimed to evaluate changes in periodontal pathogens and systemic disease indicators following the adjunctive use of probiotics for periodontal treatment. Methods: Two adults, a 64-year-old male and 71-year-old female, were selected with ethical approval and underwent comprehensive oral and systemic health assessments before and after probiotic intake with periodontal debridement. Results: There was a significant reduction in the periodontal pathogens, particularly Porphyromonas gingivalis and Treponema forsythia, and no adverse systemic indicators were observed. Moreover, a trend toward improved lipid profiles was noted, suggesting a potential positive impact on systemic health. Conclusions: This study shows the potential role of probiotics in enhancing oral health and preventing systemic diseases, thus highlighting the need for further research and clinical trials.

Bacterial canker of sweet cherry (Prunus avium L.) was observed in farmers\' orchards in Goesan, Chungbuk in 2003. Typical canker symptoms occurred on the branches or twigs of sweet cherry in early spring and bacterial exudates oozed out of the cracked barks of diseased trees. Watersoaked brown symptoms appeared on the leaves and severe infection caused thorough defoliation on the branches or twigs of sweet cherry. When severely infected branches or twigs were cut, irregular and rusty-colored symptoms in sapwood and heartwood were clearly found, indicating that they can serve as specific symptoms of bacterial canker of sweet cherry. The causal bacterium responsible for the symptoms was isolated purely from the infected sapwood of sweet cherry. Based on its morphological, physiological and biochemical characteristics, the causal bacterium was identified as Pseudomonas syringae pv. morsprunorum. The bacterium was pathogenic on sweet cherry and Japanese apricot, but not on peach, cherry, and kiwifruit. It is proposed that the disease be named as bacterial canker of sweet cherry.

대추나무 빗자루병은 가지와 잎이 위쪽으로 무성하게 총생하여 빗자루 모양이 되는 증상을 말하며, 어린나무는 2-3년 내에 말라죽는다. 또한 성목도 빗자루병에 감염되면 열매가 잘 맺지 않고, 수년이 경과한 후 고사한다. 대추나무 빗자루병에 감염되면 꽃눈이 잎으로 변하여 열매가 열리지 않으며, 병원체는 조직 속에만 있기 때문에 외부 표징이 없는 나무 전신 병해이다.

우리나라 포도재배 지역인 포천, 남양주 및 수원의 포도나무 줄기혹병에 이병된 포장으로부터 채집한 줄기혹(gall), 수액(sap) 및 근권토양으로부터 56균주의 유사 Agrobacterium를 분리하였으며, 이들 중 7균주가 포도나무 유묘의 줄기에 혹ㅇ르 형성시키는 병원성 Agrobacterium biovar의 선택배지에서의 생장, oxidase의 생성, Na L-tartrate로부터 알칼리의 성장, 2% NaCl 첨가 배지에서 생장, 3-ketolactose의 비생산, mesoerythritol과 ethanol로부터 산을 생성하지 못하는 등 Agrobacterium biovar 3인 A. vitis로 동정되었다.

다른 산업과 달리 병원/의료 산업에서는 건강 보험료 심사 평가라는 독특한 검증 과정이 필수적으로 있게 된다. 건강 보험료 심사 평가는 병원의 수익 문제 뿐 아니라 적정한 진료행위를 하는 병원이라는 이미지와도 맞물려 매우 중요한 분야이며, 특히 대형 종합병원일수록 이 부분에 많은 심사관련 인력들을 투입하여, 병원의 수익과 명예를 위해서 업무를 수행하고 있다. 본 논문은 이러한 건강보험료 청구 심사 과정에서, 사전에 수많은 진료 청구 건 중 심사 평가에서 삭감이 될 수 있는 진료 청구 건을 데이터 마이닝을 통해서 발견하여, 사전의 대비를 철저히 하고자 하는 한 국내의 대형 종합병원의 사례를 소개하고자 한다. 데이터 마이닝을 적용함에 있어, 주요한 문제점 중의 하나는 바로 지도학습 기법을 적용하기에 곤란한 데이터 불균형 문제가 발생하는 것이다. 이런 불균형 문제를 해소하고, 비교 조건 중에 가장 효율적인 삭감 예상 진료 건 탐지 모형을 만들어 내기 위하여 데이터 불균형 문제의 기본 해법인 과, Sampling 오분류 비용의 다양하고 혼합적인 적용을 통하여, 적합한 조건을 가지는 의사결정 나무 모형을 도출하였다.

그곳은 종교가 주는 편안함과 아늑함을 옮겨다 심었다. 고즈넉한 병원뜰의 성모마리아상이 몸은 물론 마음의 병까지 치유해줄 것만 같고, 병원 한 켠에 자리한 치매요양원에서 흘러나오는 엇박자 노랫소리가 평화롭게 들려온다. 노란 은행나무와 푸른 하늘이 아름다운 날, 종교가 주는 믿음과 사랑이 병원의 최첨단 의학기술과 만나 상승작용을 일으키는 포항성모병원을 찾았다.

In December of 2016, 'The Forest Protection Act' was amended partly in The National Assembly and the socalled 'Tree Doctor Act' was promulgated. Tree Doctor Act will be enforced from June 28, 2018. Under the new Act, none other than 'Tree Hospital' can do disease and pest management work for trees in public living space. The only exclusive qualification for tree hospital is a 'Tree Doctor', the government registered license which is newly established by the Act. To become a tree doctor, he/she must complete the tree doctor training courses in the designated 'Tree Doctor Academy' and pass the qualification test. Currently, Korea Forest Service is drafting the enforcement ordinances and regulations for the implement of Tree Doctor Act. When taking into consideration that the most fundamental and important discipline of the plant and tree health care is the plant pathology, and that the tree health care is a promising business for young plant pathology people, Korean Society of Plant Pathology is ought to be actively involved in the preparation of the enforcement ordinances and regulations, and help the early establishment of the new tree health care system in living spaces of Korea.

This study aimed to investigate the association of lifestyle with the copy number of periodontal pathogens. This retrospective study collected electronic health records of 102 subjects with periodontitis, including reports of bacterial genetic tests and lifestyle questionnaires. The five pathogens were analyzed as follows: Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Prevotella intermedia, and Fusobacterium nucleatum. The lifestyle questionnaire included age, sex, oral hygiene management, smoking, drinking, exercise, dietary, snacks, water intake, and sleeping time. An independent t-test or ANOVA was performed to compare the copy number of periodontal pathogens according to lifestyle (α=0.05). The copy numbers of P. gingivalis and F. nucleatum were significantly higher than those of other strains. The copy number of T. forsythia in patients who exercised was 54% lower than in those who did not (p=0.009). Other lifestyle factors did not affect the number of bacteria. Exercise habits among the lifestyles showed a association with the number of specific oral bacteria. This result suggests that a lifestyle questionnaire is essential in clinical situation and necessary to prevent and treat the periodontal disease effectively.

Methanol extracts from 207 samples of 118 plant species in 44 families were tested for their fungicidal activities against six phytopathogenic fungi. Extracts of Thuja orientalis leaf, Cinnamomum loureirii leaf, Lindera erythrocarpa barks and leaf, Pinus koraiensis wood, Hovenia dulcis wood, Koelreuteria paniculata barks, Styrax japonica wood, Camelia japonica leaf and Cleyera japonica leaf showed very strong fungicidal activity against more than two phytopathogenic fungi at a concentration of 2000 ppm. As a naturally occurring fungicide, these plants could be useful as new fungicidal products against various plant diseases induced by plant pathogens.
