이 연구의 목적은 STS 과학교육에 대한 국내 연구의 동향을 분석하고 메타분석을 통해 STS 수업모형의 적용효과를 평가하는데 있다. 연구대상 논문은 1991년부터 2006년까지 출판된 석사학위 논문 104편과 과학교육 저널에 출판된 논문 78편을 포함한 총 180편이었다. STS 수업 모형의 효과 평가에 총 56편이 선정되었다. STS 수업 모형 적용 효과의 평균효과크기는 0.40이었다. 이 결과는 STS 수업은 학생들의 과학에 대한 태도, 과학 학업 성취도, 탐구능력, 환경에 대한 태도 및 환경에 대한 지식을 향상시키는데 전통적인 수업보다 긍정적인 효과가 있었음을 의미한다. STS 수업은 환경에 대한 태도의 증진에 가장 큰 평균효과 크기를 나타내었다. 그러므로, STS 수업에서 가장 좋은 효과를 얻기 위해서는 이러한 결과들을 반영하는 것이 필요할 것이다. 향후 STS 교육에 대한 전반적인 평가를 하기 위해서는 STS 수업 모형의 효과와 과학-기술-사회의 상호관계에 대한 교사와 학생들의 이해에 대한 연구 결과를 종합하는 것이 필요하다. The purposes of this study were to analyze the domestic research trend of the STS Education and to evaluate the application effects of STS teaching model by using Meta-analysis. The selected research articles were 180 articles including 104 of the master’s theses and 76 of science education journal articles published from 1991 to 2006. For the evaluation of the effects of STS teaching and learning model, 56 articles were selected finally. The mean effect size of the application effects of STS teaching and learning was 0.40. The result indicated that STS teaching had more positive effects than the traditional teaching on enhancing student's attitude for science, academic achievement in science, inquiry ability, attitude for environment and knowledge for environment. Especially, it had shown the most positive effects on improvement in the attitude for environment. Therefore, it might be better to reflect these results for the best effect of STS teaching. To assess STS education on the whole, it is necessary to synthesize the effects of STS teaching and learning model and the results of the study on teachers’ and students’ understanding about the interrelation of science, technology and society.

몬트리올 의정서에 의해서 규제받는 CFCs와 Halon의 대체 물질인 HFC-23, HFC-125, HFC-227ea, HFC-236fa와 불활성 화합물 Ar, N₂, CO₂의 열역학적 물성인 포화압력, 밀도, 엔탈피, 점도를 비교하였다. 본 연구에서는 소화제의 물성을 문헌값을 온도의 함수로서 표시하였다. HFC화합물의 열역학적 물성은 Halon-1301과 비슷하게 나타내었다. 불활성 화합물은 주로 혼합물로 이용되지만, 불활성 화합물의 물성은 Halon-13O1에 비하며 바람직하지 않았다. For CFCs and Halons regulated by Montreal Protocol and their alternatives of HFC-23, HFC-125, HFC-227ea, HFC-236fa and the mixtures of inert gases of Ar, N₂ and CO₂, the thermodynamic properties of saturated pressure, density, enthalpy and viscosity were compared. In this study, the data from literature were expressed as a function of temperature. Thermodynamic properties of HFC compounds were similar to those of Halon-1301. Inert gas was mainly used as a mixture, but the physical properties of the inert gas does not have the favorable advantages over those of Halon-1301.

본 연구에서는 갯녹음(백화)현상이 세균생태계와 어떤 관련이 있는지에 대한 기초자료 및 정보를 얻기 위하여 갯녹음 현상이 일어난 제주도 성산과 강정지역 연안의 해수에 존재하는 세균군을 16S rRNA 증폭기법을 이용하여 조사하였다. 강정지역에서는 Alcanivorax, Paracoccus, Damselae, Pseudomonas, Rhodovulum, Silicibacter, Sulfitobacter, Roseobacter 등 다양한 종류의 세균이 분포되어 있었으며, Alcanivorax가 20%의 빈도로 가장 많이 나타났다. 반면, 성산 지역에서는 Pseudomonas속 균주가 우점종으로서 존재하였으며, Pseudomonas tolaasii(혹은 Pseudomonas corrugata)와 유연관계가 가까운 세균은 44%, Pseudomonas mandeli와 가까운 세균이 24%, Verrucomicrobiales와 가까운 세균은 4%, 기타 동정되지 않은 세균은 세 group으로 구분되었으며, 각각 8%, 8%, 12%를 차지하여, 두 곳에 분포되어 있는 세균군상이 상당한 차이점이 있음을 확인하였다. 갯녹음 지역인 강정과 성산 해수의 8월(표품 채집시기)의 수온은 27℃-27.5℃, 염분의 농도는 30.24-30.60%, pH는 8.23-8.36, 용존산소량(DO)은 각각 7.20-7.28로, 두 지역에서 매우 비슷한 것으로 조사된 바 있는데, 이는 수온이나 염분의 농도, 또는 pH보다는 다른 원인에 의하여 두 갯녹음 지역에 분포하는 세균군의 차이를 가져왔음을 제시해 주었다. In this study, the bacterial communities distributed in sea water of the whitening areas of Gangjeong and Seongsan, Jeju-do have been analyzed using the PCR amplification of 16S rRNA to obtain fundamental data and information on relationship of the whitening phenomenon and microbial ecosystem. In Gangjeong, diverse bacteria such as Alcanivorax, Paracoccus, Damselae, Pseudomonas, Rhodovulum, Silicibacier, Sulfitobacter, and Roseobacier have been found, and Alcanivorax was the most abundant clone. The most abundant clone from Seongsan was Pseudoinonas, of which Pseudomonastolaasii and Pseudonionas mandeli were most abundantly occurred in the frequency of approx 44% and 24%, respectively. Approx 4% of the bacterial clones closest to firruconiicrobiales and other unidentified clones were also found in Seongsan, suggesting there is a great discrepancy between bacterial communities from the whitening areas of Seongsan and Gangjeong. The mean tem- perature, chlorine concentration, pH, and dissolved oxygen (DO) of the sea water of Gangjeong and Seongsan in August of 2001 (sampling period) was 27℃-27.5℃, 30.24-30.60%, pH 8.23-8.36,7.20-7.28 ㎎/ℓ, suggesting other environmental factors except for the factors mentioned above might result in difference of bacterial communities distributed in both areas.

The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

윤덕미(Duck Mi Yoon),이윤우(Youn Woo Lee),박원선(W 대한통증학회 1997 The Korean Journal of Pain Vol.10 No.2

Back pain with sciatica is a common clinical syndrome that may be the expression of an uncommon pathological process. We describe a case of retroperitoneal lymphoma mimicking herniated lumbar disc. 62 year old male patient with a clinical picture of sciatica as a first manifestation of retroperitoneal lymphoma. His pain was not response to conventional therapy, and progressively worsened. We reevaluated him and found huge retroperitoneal lymphoma in his pelvic cavity. So we discuss how to identify the few who had extra attention. It is important to rule out occult pathology in patient with an atypical presentation. In assessing a patient with a low back pain, accurate evaluation require a logical, step by step method.

We treated a 56 year old male ailing of painful herpetic eruption on his 2nd, 3rd and 4th left cervical spinal segment. On the 18th day, patient also suffered an abrupt left facial palsy, accompanied with ongoing postherpetic neuralgia even though the skin eruption had been cured. This patient visited our pain clinic on his 46th day of illness and was treated with continuous cervical epidural block for 9 days, and stellate ganglion block plus oral analgesics and antidepressant for 12 days. The combination of treatments resulted in marked improvement of facial palsy and postherpetic neuralgia. A possible explanation of facial palsy accompanied with herpes zoster on cervical spinal segment could be related to Hunts hypothesis that geniculate ganglion forms a chain connecting the high cervical ganglion below. Another possibility may be related to a compression injury of the facial nerve by long-term severe edema on the soft tissue of the face, the periauricular area and parotid gland around the facial nerve, and edema on the facial nerve itself emerging out from the cranium.

Shoulder Hand Syndrome is used to describe painful disabilities of the upper extremity due to disturbances of sympathetic nerve supply. A 72 year old male developed hemiplegia on left side on the 5 days after open heart surgery of aortic valve replacement. Three months later, the patient complained of severe pain in the left upper extremity in- volving shoulder. The left hand showed swelling and flaccid paralysis. Thereafter the left stel- late garglion block with 10 ml of l% lidocaine produced prompt pain relief. Thereafter the pa- tient received 94 stellate ganglion block during 7 months which produced permanent remission of pain throughout a 1 year follow period. We recommand sympathetic block for of Shoulder Hand Syndrome following hemiplegia.
