Misinsertion of central venous catheter into the suspected vertebral vein -a case report-
양소희,정성미,박상진 대한마취통증의학회 2014 Korean Journal of Anesthesiology Vol.67 No.5
We experienced a case in which a central venous catheter (CVC) was misplaced into the wrong vein, which was mistakenfor the internal jugular vein (IJV), identified by chest x-ray and ultrasound. The vertebral vein passes through the transverseforamina from the atlas to the 6th cervical vertebra. After exiting the transverse foramen of the 6th vertebra, thevein subsequently runs anterolateral to the vertebral artery and posterior to the IJV and drains the innominate vein. Inthis case, chest x-ray and ultrasound revealed that the inserted CVC had a course very similar to the vertebral vein. Themisplacement of a CVC into the vertebral vein might occur from excessive rotation of the patient's head, which leads toalterations in the cervical vascular anatomy, and from deep insertion of the puncture needle. Therefore, it is advised, forsafe CVC insertion, to minimize a patient's head rotation and to make use of ultrasound when the anatomical structurescannot be clearly identified.
기후변화협약 대응을 위한 산업별 이산화탄소 배출실태 분석
양소희,엄영숙 전북대학교 산업경제연구소 1998 전북대학교 산업경제연구소 논문집 Vol.29 No.-
본 논문은 전 세계적으로 확산되고 있는 지구온난화에 대한 국제환경규제 강화로 인해 이산화탄소 배출량을 전 국가적 차원에서 감축시켜야 하는 바, 현재 우리나라의 이산화탄소 배출실태를 파악하여 이를 산업구조적 측면에서 문제점을 제시하고 그 대책을 제시하고자 한다. 그 이론적 배경으로 환경투입산출모형인 레온티이프모형을 이용하여 산업별 이산화탄소 배출량과 배출계수, 배출유발계수를 구하여 이를 1990년과 1995년을 비교함으로 그 변화를 살펴보았다. 현재 우리나라의 전체 이산화탄소 배출량에서 제조업의 배출비중이 절대량을 차지하고 있으며, 특히 화학, 비금속, 1차금속산업에서 배출되는 양이 전체의 30%를 넘고 있다. 배출량뿐만 아니라 산업의 중간투입물을 살펴 볼 수 있는 배출계수와 산업간의 배출유발정도를 살펴 볼 수 있는 배출유발계수에서도 이들 산업은 1, 2위를 다투고 있다. 또한 기후변화협약 가입을 계기로 연구가 시작된 1990년과 이후 1995년을 비교분석함으로 현재이산화탄소 배출구조의 문제점과 배출편중이 지난 5년간 지속되어왔음을 살펴보았다. 이에 우리나라의 산업구조는 화석연료에 의존하는 에너지 다소비형 구조이기 때문에 이러한 국제환경규제에 큰 영향을 받게 되므로 장기적으로 산업구조의 조정을 통해 이산화탄소 저 배출형의 고부가가치산업으로, 에너지절약형·환경친화적 산업구조로의 전환과 더불어 에너지이용효율 증대와 함께 3대 에너지 다소비업종의 산업내 구조고도화·고부가가치화 등의 추가적 노력이 필요하다.

BACKGROUND: Marine algae is a productive organism that is consumed as a nutritious food. However, large amounts of unused portions of the algae are incinerated as trash or dumped in the sea, causing pollution. Recycling algae is important for saving resources and conserving the environment. In this study, the fucoidan which is a major carbohydrate of marine algae was tested as a source of fertilizer for farming. METHODS AND RESULTS: The growth rate of the melon was examined after treating fucoidan and the melon growth factors, weight and length of stem were measured. To discover the mechanism of melon growth promotion of fucoidan, bacteria that decomposed fucoidan were isolated from soil and abalone. Bacillus wiedmannii and Stenotrophomonas pavanii were isolated from terrestrial soil and Pseudomonas sp. was isolated from abalone. Among these three bacteria, Pseudomonas sp. had the highest and most specific fucoidan-decomposing activity. When Pseudomonas sp. was treated with fucoidan on melon-growing soil, the growth of melon was relatively improved compared to the treatment with fucoidan alone. CONCLUSION: We found that fucoidan, the main carbohydrate of marine algae, promoted melon growth. Fucoidan-decomposing microorganisms were isolated from terrestrial soil and marine organism, and we found that these bacteria stimulated the effect of melon growth promotion of marine algae. This is the first report that confirms the fertilizer effect of marine algae and shows the use of bacteria with marine algae. .

Purpose: This study aims to provide basic data for the placement of speech-language pathologists (SLPs) in early childhood educational institutions by investigating the perception of speech-language pathology among national public and private kindergarten teachers and the needs for speech-language pathology support in early childhood educational institutions. Methods: A questionnaire survey was conducted to discover the difference in awareness of SLPs and the needs for SLPs to be placed within institutions targeting teachers of national public and private kindergarten. The collected 77 questionnaires were analyzed through descriptive statistics and χ² test using the SPSS 20. Results: First, there was no significant difference between national public and private kindergarten teachers’ perceptions of speech-language pathology. Second, there was no significant difference between groups in all questions except for one question related to the demand for placement of SLPs in institutions of national public and private kindergarten teachers. In the question of ‘Do infants with delayed language development cause harm to other infants?’, 72.7% of national and public kindergarten teachers answered ‘yes’ and 61.4% of private kindergartens answered ‘no’, showing a significant difference (p<.05). Conclusions: In Korea, national and public kindergartens have more special classes than private kindergartens, and private kindergartens rarely have special classes due to difficulties in operation. National and public kindergarten teachers, who experienced children with disabilities more closely, and private kindergarten teachers, who did not, showed similar patterns in their awareness and need for speech-language pathology, and both groups indicated that placement of SLPs in early childhood institutions is highly necessary. It is critical to identify children at risk of language disorder early and to place SLPs in institutions for appropriate intervention.
