Taean Haebyeongil is a coastal walkway designed by Taeanhaean National Park Office. This study is to present a geotourism program using Taean Haebyeongil course 6, 7 and to introduce explanation boardsto promote an effective geotourism program of the Taeanhaean National Park. Generally, geotourism program is developed by analyzing geomorphic and cultural resources of the Taean Haebyeongil course 6, 7. As a result of this study, authors suggest the following programs. In course 6(Saetbyeol-gil) from Byeongsul bay to north of Saetbyeol beach, experiencing fishing-village culture in the Byeongsul bay village may be a key geo-activity. In course 7(Baram-gil) is from south of Janggok beach to Baramarae beach, visiting Gonam Shell Mound Museum. This study is to suggest a new method of explaining geological features and cultural resources to visitors of the Taeanhaean National Park. Authors wish this new program will boost tourism of Taean Haebyeongil.

Background : Inhaled glucocorticoids are the medical treatment of choice in asthma patients. Fluticasone propionate is one of the most effective inhaled corticosteroids and has been reported to have minimal effect on the hypothalamic-pituitary-adrenal axis at the recommended dose. However, reports of long-term trials characterizing their systemic safety with chronic use are rare. This study was designed to evaluate the long-term safety of inhaled fluticasone propionate to the hypothalamic-pituitary-adrenal axis. Method : This study was conducted on 21 patients to evaluate the adrenal response to rapid ACTH stimulation test after 6 months of treatment with fluticasone propionate from $200\;{\mu}g$ to $750\;{\mu}g$ daily. The serum cortisol levels was measured to assess its effect on the hypothalamic-pituitary-adrenal axis just prior to the injection, at 30 minutes and 60 minutes after an intramuscular injection of synthetic ACTH. Result : The mean dose of inhaled fluticasone propionate was $355\;{\mu}g$ per day(SD=$174\;{\mu}g$, range=$200\;{\mu}g$ to $750\;{\mu}g$). The mean serum cortisol levels of the patients was $11.0\;{\mu}g/d{\ell}$(SD=$6.4\;{\mu}g/d{\ell}$) prior to the injection, $20.0\;{\mu}g/d{\ell}$ (SD=$7.7\;{\mu}g/d{\ell}$) after 30 minutes, and $23.0\;{\mu}g/d{\ell}$(SD=$6.3\;{\mu}g/d{\ell}$) after 60 minutes. Sixteen patients of the 21 patients had a normal response(> $18\;{\mu}g/d{\ell}$), and 5 out of the 21 patients had serum cortisol levels below the normal range after the rapid ACTH stimulation test. Conclusion: Adrenal suppression occurred in 5 out of 21 patients with 6 months treatment with inhaled fluticasone propionate.

Purpose: Trauma is one of the most common causes of death for children, and identifying severely injured children quickly in an overcrowded emergency room (ER) is difficult. Therefore, severe injury must be prevented, and the severity of injuries in children must be determined easily from their general characteristics and pre-hospital factors. Methods: Injured children younger than 15 years of age who visited the ER from June 2011 to May 2013 were enrolled. According to the revised trauma score (RTS) of the patients, the study population was divided in two groups, a severe group (RTS<7) and a mild group ($RTS{\geq}7$). The general characteristics and the pre-hospital factors were compared between the two groups. Results: Six hundred seventy-three children were enrolled, their mean age was 8.03 (${\pm}4.45$) years, and 476 (70.73%) patients were male. Of these patients, 22 patients (3.27%) were in the severe group, and 651 patients (96.73%) were in the mild group. Fewer males were in the severe group than in the mild group (50.00% vs. 71.43%, p=0.030), and children in the severe group were younger than children in the mild group (3.50 vs. 8.00 years, p=0.049). In the severe group, toddlers (54.55%, p=0.036) were the most common age group. Severe injuries occurred more often in spring (32.81%) and summer (54.56%) than in autumn (9.09%) and winter (4.55%) (p=0.026). The most common places of injury in the severe group were roads (50.00%, p=0.009), and the most common mechanisms of injury in the severe group were traffic accidents (50.00%), followed by falls (31.82%) (p=0.011). Most severely injured children were transferred by ambulance (72.73%, p=0.000). Conclusion: The results of this study may be helpful for identifying severely injured children quickly in the field and the ER. To prevent severe pediatric injuries, precautions and policies based on these results should be established.

Background: MMPs and TIMPs are important factors for abnormal remodeling the pulmonary parenchyme in idiopathic interstitial pneumonia(IIP) This study evaluated the expression of MMPs and TIMPs in the tissue of IPF, NSIP and normal control subjects. Method: The MMP-2 and -9 activity in the lung tissue was studied by gelatin zymography, and the expression of MMP-1, -2, -9, TIMP-1 and -2 in the lung tissue was measured by immunohistochemistry. Thirty five patients, who were diagnosed with IIP (UIP ; 22, NSIP ; 13), were enrolled in the immunohistochemical study. Thirteen patients with IIP (UIP ; 9, NSIP ; 4) and five patients with lung cancer were enrolled in the zymographic assay. Results: (1) The immunohistochemistry for MMP-1,-2,-9, TIMP-1 and-2 ; MMP-1,-9 and TIMP-2 were stained stronger in the UIP subjects than NSIP and the normal control. TIMP-2 was strongly stained in the UIP tissue. particularly the fibroblasts in the fibroblastic foci. (2) Zymography for MMP-2 and MMP-9 revealed MMP-2 to have prominent expression in the UIP tissue than in the NSIP tissue. Conclusions: These results suggest that the overexpression of the TIMPs and gelatinases in UIP might be important factors in the irreversible fibrosis of the lung parenchyme.

Square reefs of 2 groups installed at 1984 on mud and sandy-mud seafloor were compared with settlment conditions of those at Goheong coastal in middle-south sea of Korea at 2007. Reefs installed on mud and sandy-mud seafloor were settled to 1.9m and 2.4m, respectively. It suggest that a function of square reefs group installed on soft seafloor decrease over 50% after 20 years.
