Gyeongju, which was the central city of the ancient civilization at Silla Kingdom, has various kinds of stone cultural properties. It is significantly important to preserve historical sources of Korea. However, recent air quality data measured in Gyeongju did not show good air quality level. In order to investigate variation of the concentration of the air pollutants with meteorological condition, an air quality monitoring and an aerosol sampling were conducted during the intensive monitoring period in Gyeongju. Impacts of the meteorological factors on the air pollutants were also analyzed based on the air mass pathway categories using HYSPLIT model and the local wind patterns using MM5 model. The prevailing air mass pathways were classified into four categories as following; category Ⅰ affected by easterly marine aerosols, category Ⅱ affected by northwesterly continental aerosols, category Ⅲ affected by southwesterly continental aerosols, and category Ⅳ affected by northerly continental aerosols. The concentrations of the air quality standards were relatively lower during the fall intensive monitoring period. At that time, the easterly marine air mass pattern was dominated. The seasonal average mass concentration of PM<SUB>10,Opt</SUB>, which optically measured at the monitoring site, was the highest value of 77.6±28.3 ㎍ m?³ during the spring intensive monitoring period but the lowest value of 20.1±5.3 ㎍ m?³ during the fall intensive monitoring period. The concentrations of SO₂ and CO were relatively higher when the air mass came from the northwestern continent or the northern continent. The concentrations of SO₄²? and NO₃? - increased under the northwesterly continental condition. It was estimated that the acidic aerosols were dominated in the atmosphere of Gyeongju when the air mass came from the continental regions.

집단의사결정의 정보추출 모형(information sampling model of group discussion)은 조직 내의 의사결정과정에 필요한 모든 정보를 추출하는데 어려움이 있을 수 있음을, 조직 내의 모든 구성원들이 공유하고 있지 않은 개인의 유일정보(unshared information)의 개념을 이용하여 설명하고 있다. 선행 연구들은 개인들이 집단의사결정의 과정에서 자신들의 유일정보를 언급하기를 꺼려함에 따라, 결국 많은 경우의 집단의사결정에서 최종적으로 선택되는 대처 안은 유일정보가 배제된 공통정보만을 바탕으로 한 것이라는 점을 지적한다. 본 연구에서는 집단구성원 개인의 긍정적 기분이, 집단의사결정 과정에 있어서 원활한 정보교류를 촉진시킨 다는 것을 증명하기 위하여 개인의 기분 요소를 인위적으로 통제 및 조성(control and manipulation)하는데 성공하였으며, 실험적 정보교류과제를 개발하여 조직 내에서 양질의 의사결정을 유도할 수 있음을 입증하였다. 특히 본 연구결과에 의하면 집단구성원 개인이 긍정적 기분을 가지고 있을 때, 그들은 단지 주어진 과제를 형식적으로 마무리하는데 그치지 않고, 과제의 완성도를 높이기 위해서 가능한 모든 정보를 포괄적으로 이용하고자 하는 경향성을 보였다. 본 연구는 실험연구라는 연구방법상의 특성에 의하여 충분한 외적 타당도(external validity)를 확보할 수 없었다는 제한점은 가지고 있으나, 방법론적인 면에 있어서 긍정적 기분과 부정적 기분을 실험적으로 유도함으로써 원활한 정보교류의 촉진과 집단의사결정의 질적 향상을 위한 집단 구성원들의 노력이 부정적 기분의 감소가 아닌 긍정적 기분의 증가에 의해 유도되는 것임을 실증적으로 확인하였다.

도피불가능한 전기쇽이후 나타나는 통각억제 체계의 선택적인 활성화와 콜린성 체계의 역할

조소현,조원호 한국심리학회 한국심리학회지 생물 및 생리 Vol.4 No.1

본 연구에서는 도피불가능한 전기쇽 이후 발생하는 통각억제 체계중 어떤 요소가 선택적으로 활성화되는지, 또한 naloxone(Nal)의 사전처치에도 불구하고 통각에 대한 민감성의 감소가 약물의 투여로 인한 신경화학물질의 변화 때문인지를 밝히고자 하였다. 따라서 혐오성의 정도가 심한 도피불가능한 쇽을 가한후 hot-plate를 사용 통각에 대한 민감성을 측정한 결과, 훈련기에서 Nal집단과 Saline(Sal) 집단 모두 퍼센트 통각감소율이 높게 나타났다. 검사기에서는, Sal-Sal 집단과 Nal-Sal집단은 훈련기에서의 통각감소가 유지되는 반면에 Sal-Nal집단과 Nal-Scopolamine(Scop)집단은 각각의 생리식염수 통제집단에 비해 유의미하게 감소하였다. 이러한 사실은 도피불가능한 전기쇽 이후 통각억압 체계의 아편계와 비아편계가 선택적으로 활성화됨을 의미하고, naloxone의 사전투여 이후에 활성화되는 비아편계는 scopolamine을 투여했을때 통각감소가 역전된다는 점에 비추어 볼 때 naloxone으로 역전되지 않은 통각감소(naloxone-nonreversible hypoalgesia)는 ACh의 무스카린(muscarine) 수용기를 매개로 하여 작용했다고 할 수 있다. 이 결과는 콜린성 체계가 비아편계의 활성화에 중요한 역할을 하는 신경화학물질임을 시사해준다. The present experiment was conducted to examine which component of pain inhibition system is selectively active after inescapable electric shock and whether, inspite of naloxone pretreatment, the decrease of pain sensitivity was due to the change of neurochemical substance following drug. In result of assesing the pain sensitivity on using hot-plate apparatus after severe aversiveness of inescapable shock. Nal and Sal group were higher than baseline in the % analgesic rate in training phase. In the testing phase, both Sal-Sal and Nal-Sal group were maintained hypoalgesia but, both Sal-Nal and Nal-Scop group were significantly reduced in compared with each control group. These results indicated that opioid and nonopioid component of pain inhibition system were selectively activated after inescapable shock, and naloxone-nonreversed hypoalgesia was activated by mediation of chlinergic muscarine receptor, in view of that non-opioid hypoalgesia after naloxone pretreatment was reduced by scopolamine treatment. This results suggested that cholinergic drug is an important neurochemical substance in the activation of non-opioid hypoalgesia.

The radiopacity of six composite resins, three resin luting cements and ten filling materials were studied. The purpose was to obtain an indication of radiopacity value of different brands within each of these groups of materials and to show differences in radiopacities of filling materials and natural tooth structures. On radiographs, the optimal densities of standardized samples were determined by computer imaging system and radiopacity values of the materials were expressed in millimeter equivalent aluminum. Within the groups of materials studied, there was considerable variation in radiopacity. The composite resins of P-50, Z100 and Prisma AP.H displayed much higher radiopacities than aluminum. Panavia resin cement was shown to be similarly radiopaque to aluminum. Generally, the radiopacity of base and filling materials appeared to be higher than that of the enamel and dentin. If materials with substantial difference in radiopacity are used in combined applications for restorative treatment of teeth, lower radiopacity can interfere with the diagnosis and detection of gaps near the restoration.

Hepatocellular carcinoma(HCC)is one of common causes of cancer-related death in Korea where the majority of HCC patients were Hepaitc B virus(HBV)carriers and have cirrhosis. Transarterial chemoembolization(TACE)is commonly applied to the treatment of multinodular HCC in Korea and careful selection of candidate is important for the risk of various side effects. Besides common side effects as fever, nausea, abdominal pain and elevation of liver enzyme, TACE may predispose to hepatic failure, ischemic cholecystitis, pulmonary embolism, cerebral embolism and pneumonitis. In previous studies, some cases of pulmonary and cerebral embolism cases were reported but lipiodol pneumonitis after TACE was rarely reported. A 65-year-old woman with a multinodular HCC associated with HBV infection, was treated with TACE. Seven days after the procedure, nonspecific respiratory symptoms such as dyspnea and dry cough developed. Chest X-ray and chest computed tomography showed diffuse ground glass opacities in whole lung fields, suggestive of lipiodol pneumonitis. After several days of supportive care with steroid administration, radiologic abnormalities and subjective symptoms were much improved, considered that the disease was compatible with lipiodol pneumonitis.

Purpose: This study was done to explore time management behavior and self-efficacy in nursing students and to analyze the correlations between time management behavior and self-efficacy. Methods: The data were collected from May 12 to 20 2010 using self-report questionnaires about time management behavior and self-efficacy of nursing students. The data from 508 students were analyzed using descriptive analysis, K-means clustering, and one-way ANOVA. Results: The mean score for time management behavior was 3.03±1.11 out of a possible 5, and self-efficacy was 3.65±0.42 out of a possible 6. Four groups were identified according to time management behavior. The four groups were significantly different on self-efficacy total (p=<.05) and self-regulatory efficacy (p=.<005). The group with the highest score for time management had the highest score for self-efficacy. Conclusions: The results of the study indicate that time management behavior styles are related to self-efficacy for nursing students. Therefore, time management education programs based on the time management behavior styles are needed to increase self-efficacy in nursing students.
