This study was conducted to investigate physicochemical property changes from July 1998 to August 2001 in Mt. Bukhansan National Park. Four water sampling points were selected to measure the quality of stream water in the northeastern part of the Mt. Bukhansan National Park. The results were summarized as follows; In spring, the average pH of stream water was below the first class of the river water quality standard, while it was normal level in summer. The average electrical conductivity was about 2.3~3.3 times higher in downstream water than in upstream water during spring and summer. The contents of anions($Cl^-$, $NO{_3}^-$, $SO{_4}^{2-}$) were about 1.1~7.4 and 0.4~11.4 times higher in downstream than in upstream water, respectively. These results indicate that water quality was poorer in downstream than in upstream water. We suggest that stream water in the Mt. Bukhansan National Park should be protected from impacts of snow melting mineral particles in spring season and human impacts like wastewater of point source in summer season.

Purpose: Postoperative adhesion of the surgical field seems to be troublesome not only to the patients, but also to the surgeons. Guardix-SG<SUP>Ⱂ</SUP> is a poloxamer/alginate mixture that reduced the incidence of postoperative adhesions when it is added to the abdominal surgery in animal models and also in clinical trials. This study was a randomized, prospective, double-blinded study to evaluate the antiadhesive efficacy and safety of Guardix-SG<SUP>Ⱂ</SUP> after total thyroidectomy. Methods: A total of 89 patients who underwent total thyroidectomy between July 2008 and February 2009 in Severance Hospital and Gang-Nam Severance Hospital were randomized to either the Guardix-SG<SUP>Ⱂ</SUP> treatment group (n=45) or the non-treatmentcontrol group (n=44). The patients were asked about their clinical symptoms (hypesthesia or paresthesia on the operative site (SN) and swallowing discomfort (SW)) by using a questionnaire, and the swallowing function was evaluated using Marshmallow Esophagography by one physician. The clinical symptoms and Marshmallow Esophagography were scored according to the results of assessment. The most severe state was scored as 0 and normal was scored as 3. Results: The scores of the clinical symptoms (SN and SW) were 2.67 and 2.49 in the treatment group, and 2.09 and 1.80 in the control group, respectively, at the postoperative 6th week (P=0.001, <0.001). The scores of the Marshmallow Esophagography were 2.93 in the treatment group and 2.73 in the control group (P=0.033). Abnormal findings were seen in 2 patients (4.4%) in the treatment group and in 10 patients (22.7%) in the control group (P=0.014). Conclusion: Guardix-SG<SUP>Ⱂ</SUP> seems to be effective in preventing adhesion after thyroidectomy. Further studies involving a larger number of subjects will be needed to make an application guideline. (Korean J Endocrine Surg 2009;9: 127-132)

Scour vulnerability evaluation for shallow foundations was performed to assure bridge safety against scour in the national capital region. The case studies for 26 shallow foundations consisted of site investigation including boring test, bridge scour analysis for the design flood, bearing capacity evaluation of the bridge foundation before and after scour, and comprehensive evaluation of bridge scour vulnerability. Bridge scour vulnerability was determined based on the interdisciplinary concept considering predicted scour depth for the design floods and bearing capacity of foundation as well as dimensions of foundation. Nine of 26 shallow foundations showed the potential future vulnerability to scour with significant decrease in the bearing capacity of foundations due to scour and the remaining 17 were expected to maintain their stability against scour.

Due to a massive outbreak in the workplace and a rapid increase of industrial disaster victims, musculoskeletal disorders is recently emerging as a major issue in the field of industry safety and health. Musculoskeletal disorders has already held a high rank of occupational diseases in advanced countries and it is rapidly growing every year in Korea. In particular, it is expected that people working in the construction industry have higher rates of musculoskeletal disorders given that the construction industry requires a higher level of dependence on human labor and laborers' high intensity of physical labor outside. In this regard, targeting laborers involving in building construction, this study attempts to analyze the impact of musculoskeletal disorders which can be shown according to working hand tools, making to model musculoskeletal disorders on efficiency. As a result of analyses, it appears that there are differences in body parts that hurt skeleton and musculature between structural steel laborers and carpenters owing to different working hand tools they use. In case of structural steel laborers, they tend to feel most psychological distress when their necks and shoulders are under stress. In contrast, carpenter is likely to be agitated when their legs and knees are exposed to stress. Accordingly, this study is worthwhile by finding out different levels of musculoskeletal stress and different body parts depending on the tools laborers use, in turn proving that this has an impact on efficiency through modeling and quantifying it.

$SmFeAsO_{0.85}$ 단결정의 c-축 전도 특성

박재현,도용주,이현숙,조병기,이후종,Park, Jae-Hyun,Doh, Yong-Joo,Lee, Hyun-Sook,Cho, B.K.,Lee, Hu-Jong 한국초전도학회 2010 Progress in superconductivity Vol.11 No.2

Electrical transport properties were measured on $SmFeAsO_{0.85}$ single crystals along the c-axis for various temperatures and magnetic fields. For the measurements a mesa structure was fabricated on the surface of the single crystals. Samples showed a metallic temperature dependence of resistance and current-voltage curves without hysteretic multiple branch splitting that is usually observed in tunneling Josephson junctions. In addition, in ab-planar magnetic fields, samples did not show the Fraunhofer-type field modulation of the critical current. All these features indicate that the c-axis transport characteristics of $SmFeAsO_{0.85}$ single crystals are explained by the anisotropic bulk superconductivity rather than Josephson tunneling.
