The purpose of this study was to apply three-staged metacognition strategy(plan-monitor-control) based teaching on chair making task with corrugated cardboard in an elementary practical course to verify the effect of metacognition strategy-adopted teaching on thinking skill. 80 6th grade students from B elementary school in A city, Kyonggi province were enrolled to verity the hypothesis. A post inspection control group design was used among the designs which use the existing class structure. The metacognition strategy-adopted teaching (self-plan, self-monitoring, and self-controlling) was used on the experimental group and classic teaching method was applied on the control group. The effect was verified by post inspection method. To verify the effect of post evaluation results, t-score method was used and significance level was set as p<0.5 For statistical analysis SPSS/WIN 10.0 was used for statistical treatment. The result showed that the group which used the metacognition strategy-applied teaching came up with better performance on thinking skill in a practical arts than the control group. The conclusion derived from the above study is that metacognition strategy-adopted teaching was more effective in thinking skill in a practical arts than the class method. The study suggests that a better learning efficiency can be achieved by applying metacognition strategy in the thinking skill of a practical arts.

주지혁,최명일,김봉철 한국방송광고공사 2008 광고연구 Vol.0 No.80

Home-shopping in cable TV is considered as one of the important channels by innovative changes for the shopping. In this process, shopping hosts take a great portion, but they are not weighted in other studies. This study explores various emotions for the shopping hosts in the field of parasocial interaction and examines how those emotions affect to purchase intention. Also, the study can see over how perceived risk, perceived benefit, and attitude for the CATV home-shopping have an impact on the purchase intention. In the result, as parasocial interaction with shopping-hosts would grow, perceived risk for home-shopping is reduced, meanwhile perceived benefit is grown. Perceived risk can mediate purchase intention, and perceived benefit also can moderate attitude for homeshopping and purchase intention. It could mean that consumers can have positive image for CATV home-shopping under the conditions that parasocial interaction with shopping-hosts would be grown. The result can show that CATV home-shopping should attempt to establish parasocial interaction in order to take upper hands against open markets and internet shopping malls.

In this paper, we fabricated the MgO layer by sol-gel method and estimated possibility as a buffer layer for ferroelectric such as PZT. MgO(Magnesium Oxide) proposed as buffer layer of ferroelectric is already for much used as buffer layer in optic technology. There are many formation methods of MgO layer, but in this study, we selected the sol-gel method which is easy to control the content of material and possible for fabrication of uniform layer, then we formed thin layer through the composition of MgO and PZT solution, spin coating and annealing. To estimate the possibility as buffer layer about ferroelectric layer, we analyzed the physical and electrical characteristics about PZT on MgO layer.By SEM, AFM and XRD analysis, we could know facts that the surface condition of PZT on MgO was relatively smooth and the crystal orientation of PZT was enhanced by MgO layer. Due to the measurements of P-V, C-V and I-V characteristics of PZT/MgO capacitor structure, the polarization, fatigue and breakdown properties of PZT on MgO were much improved than those of PZT without MgO layer. Also, in MFIS structure, the PZT on MgO showed the stable memory property. These results could be compared to those of MgO buffer layer formed by sputtering, so, if studies about the composition of MgO solution and the formation of MgO layer are executed continuously, the fabrication process of MgO layer by sol-gel method can be applied as the process for buffer layer of ferroelectric.

Body temperature is controlled by thermoregulatory center of the hypothalamus. We report a case of 24 years old man with central fever. He was subjected to a partial excision of pituitary tumor compressing optic chiasm four years ago. He has received hormonal therapy for panhypothyroidism after removal of pituitary tumor. And He received gamma knife operation for partially contrast-enhancing masses in suprasellar and both hypothalamic areas that is probably postoperatively remnant or recurrent tumor of pituitary adenoma. One year after gamma knife operation, he presented with a febrile syndrome of unknown origin including rhabdomyolysis. All usual investigations proved negative. We diagnosed him as central fever with rhabdomyolysis. He received medical ICU care with cooling bed, ice pack. And his symptom improved. Postoperative hyperthermia may result following resection of the pituitary tumor. When central fever is suspected taking note of past history, a quick recognition of course of fever can help reduce the using of unnecessary antibiotics and hospital stay.

목적 : 이 연구에서는 한 사업장의 동일한 코호트내에서 직업성 요통의 발생 및 발생원인에 대해 조사하고자 하였다. 방법 : 연구대상은 1995년 12월 현재 한 조선업체에 종사하는 근로자 중에서 1995년 12월 31일 까지 요통이 이미 발생한 근로자와 1995년 당시 검진 미수검자를 제외한 9,784명을 연구대상으로 하였다. 요통 발생군은 1996년부터 1998년까지 3년간 추적 관찰하여 요통으로 4일 이상 통원 또는 입원치료를 받은 근로자로 하였다. 발생률은 요통발생 당시 연도를 기준으로 하여 해당 연도의 4일 이상 신규치료를 받은 중등도 이상의 요통근로자를 분자로 하였고, 해당년도 사업장의 종사하는 근로자 총수(과거 요통자 제외)를 분모로 간주하였다. 요통 발생군은 외상성 요통과 직업관련성 요통으로 대별하였으며, 위험요인과 질병 발생간의 관련성을 보기 위한 Cox모형에서 그 위험도를 파악하고자 할 때에는 직업성 요통만을 환자군으로 선정하였다. 결과 및 결론 . 요통 발생률은 근로자 천명당 1998년 3.1명, 1997년 8.8명, 1996년 7.8명이었다. 요통점유율의 범위는 10.99∼25.66이었다. 연령별 요통 발생률은 30대, 40대에서 높은 발생률을 보였다. 진단명에 따른 발생률은 추간판 탈출증, 염좌, 척추골절, 척추분리증, 척추협착증 순이었다 직업성 요통 발생자들의 직업적 요인을 알아보기 위하여 요통 발생 당시 작업형태를 알아본 결과, 물건을 들다가 66명(35.3%)이 발생하여 가장 큰 빈도를 차지하였고, 물건을 옮기는 과정에서 19명(10.2%)이 발생하여 2위를 차지하였고, 넘어지거나(8.6%), 물건을 당기는 자세(8.0%), 값자기 일어서다(7.5%) 순으로 요통이 발생하였다. 직업성 요통에 영향을 주는 일반적 특성 및 직업적 특성에 판한 상대위험도 및 95% 신뢰구간를 구한 결과, 요통발생에 영향을 주는 유의한 변수로는 체질량 지수(비만도), 교대여부, 중량물 취급여부였다. Objectives : This study was conducted to estimate the incidence rate, and to identify the risk factors for the occupational low back pain among shipyard workers. Methods : The study subjects consisted of 9,784 workers who were employed in a ship-building industry (excluded workers who had a history of low pack pain before 1995 or did not take periodic health examination in 1995) . The cases were 220 people who experienced back pain from January 1, 1996 to December 31, 1998. To assess risk factors for occupational low back pain, Cox propotional hazard model was used. Results : During the recent three years from 1996 to 1998, the incidence rate per 1,000 persons was 7.8 in 1996, 8.8 in 1997, and 3.1 in 1998. The main causes of work-related low back pawn were sprain, strain and disc herniation. Lifting was the most common cause of back pain (35.3%) , and carrying (10.2%) and pulling (8.0%) were followed. In Cox proportional harzard model, independent risk factors for back pain were body mass index(R.R. ; 1.54, 95% C.1. : 1.06-2.25), shift work(R.R. ; 1.65, 95% C.1. : 1.19-2.28), and lifting heavy material(R. R., 3.95, 95% C.1. : 2.29-6.82). Conclusions . This study suggests that the risk factors of back pawn In shipyard work-ers were body mass index, shift work and lifting.

This study was to investigate the effects on hematological indices and heinz body formation in various intensity, Male Sprague-Dawley rats were randomly divided into the control group, the low-intensity exercise group, nigh-intensity exercise group (n=7 in each group). Animals of the low-intensity exercise groups were put on exercise 30 min per 1 day, 5 days per week for 6-weeks. Animals of the high-intensity exercise groups were put on exercise 120 min per 1 day, 5 days per week for 6-weeks. Red blood cell count (RBC), hemoglobin (Hgb), hematocrit (Hct), mean ceil volume (MCV), mean hemoglobin corpuscular (MCH), mean hemoglobin corpuscular concentration (MCHC) were analyzed in automated hematology analyzer (ABX Hematology MICROS 60) from 10㎕ of whole blood. Erythrocyte morphology were evaluated in super vital (Brilliant cresyl blue stain) stained blood films. In the present results, Hg, MCHC in the high-intensity exercise group was significantly decreased compared with the different exercise intensity and the control group. MCV in the high-intensity exercise group was significantly increased compared with the different exercise intensity end the control group. Heinz body formation in the high-intensity exercise group was significantly increased compared with the different exercise intensity and the control group. In the present study, it can be suggested that intensity of exercise can influence hematological variables and heinz body formation. These findings suggest that high intensity exercise induces oxidative damage to erythrocyte.

gemcitabine과 carboplatin으로 치료받은 경력이 있는 진행성 비소세포폐암 환자 25명을 대상으로 2차 화학요법으로 paclitaxel과 cisplatin을 사용하여 다음과 같은 결과를 확인하였다. 전체 25명 중 5명에서 부분반응이 관찰되었으며, 반응군의 반응지속기간은 2~11개월로 중앙값 4.3개월이었다. 전체 환자의 무진행생존기간은 0~11개월로 중앙값 3.3개월이었으며, 생존기간은 1.3~39개월로 중앙값 7.4개월이었다. 전체 83회의 화학요법 중 WHO 3도의 혈소판감소증이 1회에서만 관찰되었으며, 비혈액학적 부작용도 감내할 만 하였다. 이상의 결과, paclitaxel과 cisplatin 복합화학요법은 진행성 비소세포폐암 환자에서 2차 요법으로 사용하였을 때 부작용이 적으며 효과적인 치료법의 하나로 판단된다. Background: To evaluate the efficacy and safety of paclitaxel and cisplatin against advanced non-small cell lung cancer (NSCLC) as a second-line chemotherapy. Subjects and Methods: Twenty-five patients were enrolled. The patients received 200 mg/㎡ paclitaxel as a 3-hour intravenous infusion and 60 mg/㎡ cisplatin as 30-minute intravenous infusion with vigorous hydration on day 1 every 28 days. The response was assessed every 2 cycles. Results: All 25 patients were assessed for their response and toxicity. Partial responses were observed in 5 patients. The overall response rate was 20%(95% confidence interval, 4%~36%) and the median response duration was 4.5(range, 2-11) months. The median time to progression was 3.3(range, 0-14) months. The median overall survival of all patients was 7.4(range, 1.3-39) months. The hematologic toxicities were minor and easily controlled. Conclusion: The combination chemotherapy of paclitaxel and cisplatin as a second-line treatment has a moderate efficacy with an acceptable toxicity in patients with advanced NSCLC.
