Acinetobacter baumannii는 광범위한 항생제에 대한 저항성으로 인해 감염된 환자의 사망률이 높아지는 적색 경보 병원체로 분류됩니다. 이 연구에서 다제 내성 A. baumannii(MRAB)의 18가지 임상 분리 균주에 대해 일부 에센셜 오일(티트리, 로즈마리, 라벤더 오일)의 항균 활성을 평가하고자 하였다. Carbapenemase 선별을 위한 Hodge 시험법은 A. baumannii의 20 가지 균주가 모두 imipenem에 내성이 있음을 보여주었습니다. 다제 내성 미생물의 확인은 VITEK 시스템을 통해 수행하였다. 에센셜 오일의 항균 활성은 MRAB에 대한 디스크 확산 방법으로 평가하였다. 디스크 확산 방법에서 tee tree는 라벤더 오일에 비해 억제 크기가 가장 크게 증가했으며, 로즈마리는 항균 효과가 없었다. 티 트리 오일은 가장 일반적인 인간 병원균 및 MRAB 감염의 치료 및 예방을 위한 대체 천연 제품으로 유용할 것으로 보인다. 따라서 이 연구의 결과는 다제 내성 A. baumannii의 항균 효과를 입증했으며, 미래에 천연 에센셜 오일을 사용하는 손 소독제와 같은 항균제로 사용될 것으로 예상됩니다.

Purpose: This study was to analyze clinical and epidemiological characteristics of elderly patients who were admitted to the emergency department (ED) due to falls by separating male and female. Methods: We retrospectively analyzed the fall patients aged 65 years or older from the data of the in-depth surveillance study of injured patients visit to the ED under the supervision of the Korea Centers for Disease Control and Prevention (KCDC) from 2011 to 2016 by separating male and female. Results: A total of 361,588 elderly fall patients were analyzed and, among them, 14,429 (37.3%) were males and 24,208 (62.7%) were females. Male and female showed similar frequency of damage happening season. However, they showed falling accident mostly on winter. The time of injury occurrence is mostly from 12:00 to 18:00 with 4,949 (34.3%) male and 8,564 (35.4%) female. Most falls occurred in daily activities, accounting for 7,614 (52.8%) in males and 14,957 (61.8%) in females, respectively. Unintentional damage accounted for the most part and 7,395 (51.2%) of male and 15,343 (63.4%) of female were injured indoors. Head and neck were the most common site of injuring, with 8,392 (58.2%) in males and 7,851 (32.4%) in females. According to ED examination outcomes, most of the patients were discharged, while the majority of the hospitalized patients were admitted to the general patient room. Conclusions: The elderly falls occurred mostly from 12:00 to 18:00, during winter and to elderly women. Also, they happened unintentionally indoors in everyday life, mostly. Proved clinical, epidemiological characteristics from this research will be used as useful indicator at validity research of development of prevent program of falling accident for elderly people.

This study was carried out to investigate the flora of six islands belonging to the Gogunsan Archipelago (i.e., Sinsi-do, Seonyu-do, Munyeo-do, Yami-do, Bian-do, and Duri-do) in the Korean Peninsula. As results of five field surveys from March to October of 2016, we have identified 575 total taxa, representing 527 species, five subspecies, 42 varieties, and one hybrid, placed in 358 genera and 118 families. Of these 575 taxa, four are endemic to Korea, six taxa are listed on the Korean Red List of threatened species, 67 are floristic regional indicator plants, and 74 are invasive alien species. In this study, we compared species richness among the islands, and find that the larger the islands, the higher the species richness. In the case of habitat affinity types, forest species were most common, followed by farmland, seacoast, bare ground and wetland species. From similarity analyses based on the composition of vascular plants, each island did not exhibit either local specificity or unique diversity. On the contrary, the proportion of invasive alien and ruderal species may increase by human activities. Investigations and analyses of island flora such as this are important to assess the current status of the flora, predict future vegetation patterns and the spread of the alien species, and establish managment plans of plant diversity.

Objective: Degenerative knee arthritis is the most common disease that occurs in older people. Constriction-induced movement therapy (CIMT) has been reported to be as an effective treatment for the impairments, such as asymmetric weight-bearing and reduced balance that occurs after receiving a total knee replacement (TKR). Game-based rehabilitation training for persons with TKR is interesting and provides a variety of feedback. Design: Randomized controlled trial. Methods: Thirty-six subjects with TKR were randomly assigned to either the CIMT game training (n=12), general game training (n=12), or the control (n=12) group. Each group underwent twelve sessions (30 min/d, 3 d/wk for 4 weeks). In the CIMT game training group, the application of CIMT adjusted the weight of the pressure delivered from the two boards used in Wii games. In the general game training group, the game was played without adjusting the weight of pressure. The game training used the Wii Fit's Ski Slalom application. Subjects were assessed with the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the Activities-specific Balance Confidence (ABC) Scale. Results: All three groups showed significant improvements in pain, stiffness and physical function, total WOMAC scores, and ABC scores after the intervention (p<0.05). Significant differences were observed in physical function, total WOMAC scores, and ABC scores of the CIMT game training group compared with the other groups (p<0.05). Conclusions: The CIMT game training and general game training exhibited improvements on stiffness, but the CIMT game training exhibited a larger effect on lower extremity function and balance confidence levels.

This study was conducted to grasp users' preferences and behavior of forest paths and to provide basic data for forest path construction in the future. Among forest path users, males and females over 20 years old were surveyed on forest path preferences, motives for visiting, using time and distance, companions, and sources for obtaining information on forest paths. A total of 587 people participated in the questionnaire, and cross-analysis was conducted simultaneously using the SPSS statistical program. In analyzing the preference of forest paths, it was found that male and the general public preferred trekking path for activities while female and foresters preferred forest path for relaxation and healing (p<0.05). As for the motives for visiting forest paths, the response that they visited for a walk/rest was the highest in gender, occupation, and age group. As for the number of annual visits, less than 5 was the highest in overall, and foresters tended to visit forest path more often than the general public, and the number of visits to the forest paths increased with age (p<0.01). The most common route to acquire information about forest paths is the Internet, while the Internet use is relatively low in those over 60s (p<0.05). The response ratio of accompanying their family in visiting forest paths were the highest, while the response in their 20s and 60s was the most in accompanying their friends (p<0.05).
