The purpose of this study is to quantitatively evaluate the amount of carbon storage for trees in forest ecosystem to support the foundation for carbon neutrality implementation in Korea National Park. It targeted 22 national parks designated and managed as national parks in Korea, and conducted research on forest trees in the terrestrial ecosystem among various natural and ecological carbon sink. The survey and analysis method followed the IPCC guidelines and the National Greenhouse Gas Inventory in Korea. The amount of tree carbon storage in the forest ecosystem of Korea National Park was confirmed to be about 218,505 thousand CO₂-ton and the amount of carbon storage per unit area was 570.8 CO₂-ton per hectare. Compared to 299.7 CO₂-ton per hectare, the average carbon storage per unit area of the entire Korean forest, it was found that about twice as much carbon was stored when assuming the same area. In other words, it means that the tree carbon storage function of the national park is about twice as high as that of the average tree carbon storage function of entire Korean forest. It has great implications in Korea National Park not only provides biodiversity promotion and exploration services as a national protected area, but also performs excellent functions as a carbon sink.

Graphene: Position‐ and Morphology‐Controlled ZnO Nanostructures Grown on Graphene Layers (Adv. Mater. 41/2012)

Kim, Yong‐,Jin,Yoo, Hyobin,Lee, Chul‐,Ho,Park, Jun Beom,Baek, Hyeonjun,Kim, Miyoung,Yi, Gyu‐,Chul WILEY‐VCH Verlag 2012 Advanced Materials Vol.24 No.41

<P>On page 5565, Gyu‐Chul Yi and co‐workers grow position‐ and morphology‐controlled ZnO nanowalls in prescribed positions on graphene layers. The nanowalls are grown to produce a variety of shapes from simple circles to text at the microscale. The selective growth of high quality ZnO nanowalls is investigated by electron microscopy and optical spectroscopy. The hybrid nanostructure can be exploited to fabricate various nanodevices including microarrays of nanotube LEDs. </P>

Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of death or acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps; one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.

저자들은 객혈을 주소로 내원한 75세 남자 환자에서 기관지내시경 육안 소견상 양성 종양이 의심 되었으나 조직 검사상 지방종을 확진하지 못하였고 악성종양을 배제할 수 없는 상황에서 종괴에 의한 왼쪽 폐의 허탈과 농흉 때문에 수술적 치료를 시행 하였으며, 수술 결과 기관지 지방종에 의한 폐허탈, 농흉 및 기관지 확장증, 이로 인한 객혈이 발생한 예가 있어 보고하는 바이다. Lipoma is a common neoplasm on soft tissues. However, bronchial lipoma is rare benign tumor. Patients with bronchial lipoma might have a malignant potential, and there were case reports of lung cancer accompanied with lipoma. Therefore, it should initially be treated by fibrotic bronchoscopy or surgery. We encountered a 75 year-old male patients with bronchial lipoma, causing hemoptysis.

Background : Gastric cancer is the most common malignant tumor in Korea. surgical operation is one of the major treatment modalities for gastric cancer patients. Therefore, gastrectomy is one of the most common procedures in General Surgery. There were variation in length of hospital stay and medical treatment for gastrectomy between three surgeons at Asan Medical Center. Clinical pathways have received considerable attention as a tool for recucing the medical practice variation, increasing the efficiency of care process, and improving the quality of care. The aim of this study was to evaluate the effect of a clinical pathway for gastrectomy in gastric cancer patients. Methods : The clinical pathway for gastrectomy was developed and implemented by a multidisciplinary group in Asan Medical Center. A computerized clinical pathway program was developed and revised after a pilot test. A total of 145 patients underwent gastrectomy by three surgeons at Asan Medical Center. We compared the length of hospital stay, patient satisfaction, and unplanned readmission rate between the pre-pathway group(n=67) and the post-pathway group(n=78). We also investigated the degree of satisfaction among the physicians and nurses who were main end-users of the clinical pathway. Results : The clinical pathway was applied to all target patients. The average length of hospital stay was shortened from 12.7days to 10.6days(p<0.01). The degree of patient satisfaction with the care process changed from 90.3% to 89.2% after the implementation of the clinical pathway, but the difference was of satistically significant(p=0.761). Unplanned readmission rate was 2.9% in the pre-pathway group. More than 90% of physicians and nurses answered that the clinical pathway had been a useful tool in their medical practice. Conclusions : The findings of the study demonstrated that implementation of the clinical pathway for gastrectomy produced substantial reduction in the length of hospital stay while improving the quality of patient outcomes. The computerized clinical pathway program can be used as one of the powerful patient management tools for reducing the practice variations and increasing the efficiency of care process in Korea hospital settings.
