Objectives: This study aimed to survey the characteristics of air quality and meteorological conditions in a greenway park. Methods: We measured meteorological and health related factors, including noise, particulate matter ($PM_{10}$) and selected gaseous air pollutants at three locations in a greenway park and on a general roadside as comparison. The measurements were repeated four times from April to October 2014. Results: The average air temperature in the greenway park was $20.7^{\circ}C$ which was $1-2^{\circ}C$ lower than on the general roadside. The average $PM_{10}$ concentration in the greenway park was $85.0{\mu}g/m^3$, a level 2-3 times lower than that at the roadside. The noise level at the greenway site was 4.4 dB(A)- 23.0 dB(A) lower than at the roadside. The average CO, $CO_2$, $SO_2$ and NOx concentrations in the greenway park were lower than at the roadside. The average phytoncide and anions concentrations in the greenway park were higher than at the roadside. Conclusions: The urban forest of the greenway park may have some impact on air quality and meteorological conditions.

The Anti-cancer Effect of Oriental Medicine Chung-Ri-Ja-Gam-Tang in the Mouse with Metastatic Lung Cancer. Proceedings of International Symposium on East-West Medicine, Seoul. 231-243, 1999.-The oriental medicine Chung-Ri-Ja-Gam-Tang is an herbal medicine which has been used for pulmonary diseases and known as having immune stimulatory effects. It has been known effective in lung cancer. So we studied the effects and the mechanisms of this herbal medicine it the mouse with metastatic lung cancer. The metastatic lung cancer of the mouse was produced with melnoma cell line(B16BL/6).5×10□/mouse tumor cells were injected intravenously to the CDF1 mouse via tail vein. The mice were divided 4 groups. The first group was treated with 50mg/kg extract of Chung-Ri-Ja-Gam-Tang per oral for 10 days after cancer cell injection, second group treated with saline after cancer cell injection, the third group with medicine without cancer cell, and the last group with saline only. After 10 days treatments some of the mice were scarificed and the lung and spleen was removed. The survival duration, weight change, the number of metastatic cancer nodule of the lung, the NK cell activity, the capacity of cytokines(INF-γ,INF-α,IL-2) production and the proliferation activities of mouse lymphocytes were measured. The surival times of the group 1 mice were longer and the weight loss was less than the group 2 significantly. The number of the metastatic nodule of the lung were decresed in the group 1 than the group 2. The production of INF-γ,was increase in group 2 than group 3 and 4, IL-2 production was increased in group 1 than group 2,3,4 significantly. There was no difference in TNF- α production and proliferation activity of lymphocyte in each group. The NK cell activity was significantly increased in group 1 than group 2,3,4. We conclude that the Chung-Ri-Ja-Gam-Tang has the effect of increasing the NK cell activity of the CDF1 mouse with metastatic lung cancer(B16BL/6). And it is suggested that the increased production of the IL-2 is the mechanisms of enhanced NK cell activity.

Purpose : The purpose of this study was to develop the radiographic technique for detecting the demineralization which is known as indication of dental caries. Materials and Methods : This technique was based on the comparing of multiple radiographs which was irradiated by multiple X-ray spectra. For the meaningful comparing, the multiple radiographs were reconstructed to the dosimetrically consistent images using a standard material. The difference of resulting images of same target with multiple spectra represents the difference of response of material as regards the spectra. Results : We have found about 10% of demineralization of dental hard tissues particularly in the proximal region through the analyzing of differences. Conclusion : Most intriguing thing in this investigation was that the method to analyze difference shows us to an anatomic structure of dental hard tissues even if absolute values of optical density were excluded during the procedures.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Afferent loop syndrome is an uncommon complication of a gastrectomy and Billroth Ⅱ reconstruction. It may cause symtoms at any time from the first postoperative day to many years after the gastrectomy. Afferent loop syndrome is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate afferent loop syndrome from other cause of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing afferent loop syndrome. We experienced one case of chronic afferent loop syndrome with acute pancreatitis. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. We report this case with a review of relevant literatures.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

The radiographic findings of soft tissue calcification in the oral and maxillofacial area was analysed using panoramic, skull P-A and intraoral radiographs in 250 patients. The obtained results were as follows: 1. Salivary stone had the highest rate of occurrence at 46%(116 cases), followed by lymph node calcification(97 cases), phlebolith(21 cases), multiple miliary osteoma(15 cases), antrolith(1 case), vessel calcification(1 case) and cysticercosis(1 case). 2. The prevalence of salivary stone was slightly higher in female, on the right side and in the middle-aged group and was especially higher in the submandibular gland(83%). The majority of them were round-shaped, homogeneously radiopaque and associated with sialodochitis. 3. The prevalence of lymph node calcification was higher in the female and old-aged group. Irregular shape and radiopaque bodies were seen in the cervical area, bilaterally. 4. The prevalence of phlebolith was slightly higher in the male, and the third decade group. The radiopaque bodies were 4-8 mm in diameter and had laminated appearance. 5. The prevalence of multiple miliary osteoma was higher in old-aged females. The numerous doughnut-shaped radiopaque bodies, sized 2-4 mm in diameter, were seen bilaterally in the cheek and were usually associated with the edentulous ridge.

This study was conducted in order to measure formaldehyde emission with the passing of one year from particleboard(two kinds of raw material's shape - sliver and strand) bonded with Urea resin which was made of different F/U molar ratio. The Urea resin was manufactured six kinds of Formaldehyde/Urea molar ratio 1.0, 1.2, 1.4, 1.6, 1.8 and 2.0. Formaldehyde emission values were compared at 1, 3, 7, 15, 30, 90, 150, 250, and 365 days after board manufactured. The results were as follows : 1. I year after board manufactured, both Sliver and Strand Particleboard satisfied the emission limit (E₂: 5㎎/ℓ - F3140 classification) of KS standard with 1.0, 1.2, 1.4 and 1.6. 2. The Partidcleboards with F/U molar ratio 1.4 and 1.6 satisfied E2 limit only in 150 days and 365 days respectively. 3. Formaldehyde emission amount of Sliver Particleboard was similar to Strand Particleboard depended on each F/U molar ratio. However, the formaldehyde emission pattern was influenced with the shape of raw materials(particle shape).

The effect of the pretreatment by solvent extraction with various solvent on the saccharification of poplar (Populus euramericana)was studied. The solvent system was phenol/H_2O (uncatalyzed, HCl and NaOH catalyzed), butanol/H_2O, ethanol/H_2O and ethylendiamine/H_2O solvent system. When the poplar was pretreated by phenol/H_2O uncatalyzed system, the best result of the enzymatic saccharification was total of 43.87 g/L reducing sugar produced and 83.35% of carbohydrated conversion was obatined at 190℃, 60 minutes. Total wood yield and the lignin removal were 46.3% and 96.17%, respectively. The use of acid, base catalyst and the others solvents was unsuitable to increase the efficiency of saccharification.
