Vygotsky의 ZPD이론에 기초한 유아 교수-학습방법에의 적용

이현섭,하은숙 진주산업대학교 2001 論文集 Vol.40 No.-

The purpose of this study are to investigate Vygotsky's Zone of Proximal Development (ZPD) theory, and to discuss his theory in terms of the practice of early childhood education. Based on Vygotsky's theory of ZPD, the following suggestions can be drawn : 1. In order to provide the foundation of learning of young children, teachers should evaluate them using dynamic method of assessing their ZPD. 2. Since teacher are one of the most important factors influencing children's development, they should try to improve their professional quality. 3. The ratio of teacher vs children should be lower and children should be divided into small groups for more effective scaffolding. 4. Mixed age group is more effective than homogeneous age group in order to enhance young children's active peer interaction. 5. Teacher should select and provide children with various activities in which children can experience cooperation with peers and social interaction with other using language. 6. Teacher should establish an appropriate educational objectives for each child on the basis of the results of the dynamic assessment

국제상거래에 대한 ebXML 적용상의 법적 문제점

이은섭,조현숙 국제무역학회 2002 국제무역연구 Vol.8 No.1

전통적으로 전자무역거래에 적용되어온 EDI의 단점을 보완하고 특히 개방된 네트워크 상에서 좀더 효율적인 전자거래를 하기 위해 전자상거래XML(Electronic business XML: ebXML)이 추진되고 있다. ebXML이 무역거래에 실용화되기 위해서는 기술적 발전을 다룰 수 있는 법적 기반이 마련되어야 한다. 본 연구의 목적은 ebXML을 국제무역거래에 적용시킬 경우 법적 문제점을 찾아보고 ebXML을 무역거래에 효율적으로 활용시키기 위한 법률적 보완점을 제시하는데 있다. ebXML 거래가 이루어지기 위해서는 교환되는 전자문서의 법적 효력을 확보하는 것과 사이버공간에서 안정적인 거래를 할 수 있어야 한다. 이를 위해 ebXML 구성 내용을 명확히 해야 하고 법령의 정비가 이루어져야할 것이다. Electronic business XML(ebXML) is under process to develop to supplement EDI's shortcomings and to facilitate the electronic trade more efficiently in the open network system. For the efficient application of ebXML to the international trade, legal arrangements should be established to cover the technological development in this field. This paper is to examine the legal problems relating to the actual application of ebXML model to suggest the directions to regulate the transactions through ebXML. It is required to secure the legal effect of the electronic documents through ebXML and to establish the legal provisions for the safe transaction on cyberspace to apply the ebXML to the international trade. For this, the technical and structural mechanism of ebXML should be elaborated, which should be supported by the proper legal system.

Spent pig bone was consist of hydroxyapatite. And then we thought that it have a possibility as a adsorbent. The preparation of bone char prepared from spent pig bone in this study. We study on the recycling possibility as a adsorbent is able to adsorb copper ion from their single aqueous solutions. The results are summarized as follows. Bone char that prepared from spent pig bone at 105, 400, 700℃. The adsorption removal efficiency of copper ion onto bone char as adsorbent was above 90% for 15 hours. Increase in the initial pH of the copper ion solution result in an increase in the copper ion uptake per unit weight of the adsorbent. Freundlich isotherm model was found to be applicable for the experiment data of copper ion. The results showed that spent pig bone can be used for the absorption of the copper ion.

The garlic contains, along with many kinds of organic compounds, some allylsulfides, amino acids, thiolactic acid, glutathione and some vitamins has expected to yield the effect of detoxication of heavy metal poisoning by forming thiochelate compounds when reacting with heavy metals in bodies. To examine this hypothesis, especially for the effect of garlic on the detoxication of Cd-poisoning in testis, one of the most sensitive target organs of Cd-poisoning, a total of 60 albino rats were sampled as experimental animals and devided into six group: a group given with only 100ppm cadmium; one given 3.35% garlic; two groups given with 1.70% and 6.67% garlic in addition to 100ppm cadmium; one given 400ppm garlic oil and a group of controls. After rearing the rats with different meals and water as indicathe above for 12 weeks, alkaline phosphatase activity, cadmium content in testis and pathological changers in testicular tissue were measured and observed to have following results; The group given with 6.67% garlic in addition to 100ppm cadmium showed significant decrease of toxic changes due to cadmium poisoning in terms of alkaline phosphatase activity, cadmium accumulation in testis, and pathological change of testicular of testicular tissues. On the other hand, the group given 100ppm cadmium only showed significantly higher cadmium in testis, more decrease of alkaline phosphatase activity and definite pathological findings of hydropic degeneration and necrosis with atrophy n seminiferous tubules and degenerative changes in germinal epithelium of testis. The group given with 400ppm garlic oil in addition to cadmium showed in midline reaction in every above toxic changes.

Comparison results of callus formation ratio from seed explants, callus sizes, regeneration ratios from callus and regeneration efficiency [calculated by following formular; callus formation ratio(%) × regeneration ratio(%)/100]for 27 ochardgrass (Dactylis glomerata L.)varieties imported and Hapsung 2 developed in Korea are as follows; 1. Among ochardgrass varieties showing more than 50% callus formation ratios, the descending order of callus formation ratio after bedding the seed explants for 4 weeks was 93>Sparta>Pizza>Condor>Lidaglo>Glorus>Hapsung2>Frode. 2. The callus sizes after bedding for 4 weeks were in the range of φ 0.43cm~4.2cm in which there was 10 times size difference between the largest one and the smallest one but most of them were between φ2.5cm~4cm. 3. The regeneration ratio from callus among varieties were in the range of 0~36% and descending order of the upper 6 varieties was Plano>Akimidori>Justus>Lidacta>Currie>Hall mark. 4. The regeneration efficiency which is calculated by the ratios of regeneration from seed explant numbers was between 0 to 17.4% among which Justus showed the highest value in the 4-week treatment. 5. The correlation between callus formation ratios and the callus sizes, callus formation ratios and regeneration efficiency, and callus sizes and regeneration efficiency were r=0.5765, r=0.6365 and r=0.6246, respectively in 4-week callus and all the correlations were significant on the 1% level. 6. In 6-week callus, the descending order callus formation ratios from seed sxplants for the best 6 varieties was Condor>Sparta>93M>Justus>Potomac>Lidaglo>Frode. 7. The callus sizes formed were between φ1.5~5.7cm in which Sparta, the largest one of φ5.7cm was five times larger than the smallest one. The callus size of the control variety. Hapsung 2 was φ3.8cm, which belonged to larger size. 8. Regeneration ratio showed a great deviation among varieties from 6-week old calli by showing from 0% to 100% in which all the calli were regenerated in Plano while no callus was regenerated in Juno, 9. The range of regeneration effciency was between 0~28% among varieties in which the values from 6-week callus treatment were larger than those from 4-week callus treatment. Especially, the value of Potomac in 6-week was 3 times larger than that in 4-week. 10. The correlation between callus formation ratios and the callus sizes, callus formation ratios and regeneration efficiency, and callus sizes and regeneration effciency were r=0.8369, r=0.6683 and r=0.5937, respectively in 6-week callus, and all the correlations were significant on the 1% level.

박은하,도연실,양정채,강미라,서현주,정숙인,손준성,기현균,오원섭,백경란,송재훈 대한감염학회 2004 감염과 화학요법 Vol.36 No.6

연쇄알구균에 의한 급성 인후염 후 발생한 반응성 관절염은 급성 류마티스열의 개정된 진단기준을 충족하지 못하면서, 지속적 혹은 재발성의 비이동성 관절염과 발열, 홍반성 결절, 일시적 간기능 이상 등을 보이면서 심장염과 무도증을 드물게 동반하는 질환이다. 따라서, 발열을 동반한 급성 관절염 환자에서 감별해야 할 질환 중의 하나이며, 심근염 예방을 위한 페니실린 요법의 적응증 및 기간에 대해서는 아직 이론이 많은 상황으로, 보다 광범위한 연구가 필요하다. 저자들은 연쇄알구균에 의한 급성 인후염 1주 후에 발생한 하지의 다발성 비이동성 관절염과 함께 결절홍반 및 일시적 간기능 이상을 보인 환자에서 PSRA로 진단하고 비스테로이드성 항염증제 및 스테로이드로 성공적인 치료를 하였기에 이를 문헌 고찰과 함께 보고하는 바이다. Poststreptococcal reactive arthritis (PSRA) is associated with recent streptococcal infections. However, PSRA is distinct from acute rheumatic fever by its clinical manifestations: non-migrating arthritis, erythema nodosum or erythema multiforme, and transient elevation of serum transaminases. We experienced a 33-year-old man who presented with fever, arthritis of both knees and ankles, and erythema nodosums on extensor surfaces of lower legs which developed 6 days after the onset of pharyngitis symptoms. Blood and urine cultures were negative. Throat culture was negative for group A β-hemolytic streptococcus. The ASO titers increased up to 2080 IU/mL in sequential monitoring. The result of bone scan was compatible to arthritis of both knees and ankles. There were no signs or symptom of carditis. He showed clinical improvement with anti-inflammatory drugs (naproxen 1,000 mg/day and prednisolone 7.5 mg/d). PSRA should be included in the differential diagnosis of patients presenting with arthritis combined with fever.

황춘섭,오은정 慶熙大學校 1996 論文集 Vol.25 No.-

This research is interested in the concept of consumer's fashion involvement which makes influences on the consumer's information-searching pattern. The main object of the approach is the mothers of the babies under the age 3, who can be considered the actual babies' costumes buyers. The writer tried to find out whether the mother's own fashion involvement is in any proportionate relation with their babies' costumes involvement and also to study their various attitudes toward the magazine advertising of babies' costumes. The writer hope this research could provide babies' costumes industries with basic data that can help to establish more effectual advertising strategies. To achieve the purpose of the present research. The writer established 4 more detailed study points as follows: 1) to find out the appeal patterns of babies' costumes advertisements especially favored by the mothers 2) to find out the relationship between the mothers' own fashion involvement and their involvement in the babies'costumes advertisement 3) to find out their various degree of involvement in the babies' costumes advertisement according to their fashion involvement degree. This research was conducted through the survey method using stimulating objects and questionnaires. The experimental advertisements used in this survey were selected among the actual magazine advertising, and reproduced with the help of an expert in advertisement production who is a present member of an advertising company. During the reproduction process, all the brand names were deleted in order to control the brand familiarity and the brand preference which might have an influence on the consumer's attitude toward specific advertisements. The appeal patterns of the magazine advertising materials used in this research was limited to only 3 kinds that is, the appeal to reason, the mixed appeal to reason and emotion, the appeal to emotion. The questionnaire includes question items designed to identify the attitudes toward advertisements, the degree of fashion involvement, the opinions on utility of magazine advertising of babies costumes, and the present magazine subscription situation, the source of information on babies' costumes purchase, 394 samples were extracted through the convenience sampling method among the mothers of babies under the age 3. presently living in Seoul. The data was analyzed by Frequency, paired t-test, Chi-square, Correlation and Oneway. The result of the research can be summarized as follows: 1) Among the 3 kinds of advertisement appeal patterns, most preference was shown to the mixed appeal to reason and emotion. The appeal to emotion followed next and then comes the appeal to reason. 2) The higher the degree of mothers' own fashion involvement, the higher their involvement in their babies'costumes. 3) Mothers' fashion involvement degree doesn't make any difference in their attitudes toward the advertisement of babies' costumes.

1978년의 국제운송 조약이 해상보험에 미치는 영향

이은섭,서성석 釜山 大學校 經營 經濟 硏究所 1999 經營 經濟 硏究 Vol.18 No.1

1978년 함부르크규칙의 제정을 전후하여 함부르크규칙이 이중보험에 미치는 영향과 관련한 논의가 심각하게 이루어진 이래 지난 20여년간의 논의를 요약해 보면 다음과 같다. 즉 동규칙의 지지자들에 따르면 함부르크규칙의 운송인에 대한 추정과일책임주의 적용이 해운기업의 효율적인 위험관리의 실행 및 운송물건에 대한 주의정도를 높임으로써 사고의 발생을 감소시켜 이중보험 및 전체적인 보험비용을 감소시킬 것이라 한다. 이에 대한 반대론자 등에 따르면 함부르크규칙의 규정은 헤이그나 헤이그-비스비규칙의 그것보다 애매하기 때문에 해석을 둘러싼 소송비용을 증가시키고, 운송인에 의한 책임보험에로의 위험의 전가는 이중보험문제를 더욱 악화시켜 전체적인 보험비용을 증가시킬 것이라 한다. 이중보험과 관련한 함부르크규칙의 평가는 객관적으로 신뢰할만한 실증분석을 통하여 최종적으로 이루어질 수 있겠으나 현재의 상황으로는 이 분석을 위한 자료의 확보가 불가능하다. 이러한 한계점을 염두에 두고 본 논문에서는 동 규칙의 해석을 통하여 결론을 내리고 있다. 함부르크규칙의 해석론적 평가를 한 결과, 단기적으로는 동규칙이 이중보험문제에 대하여 특이할만한 영향을 미칠 것으로 보이지 않으며 결국 함부르크규칙이 지향하는 이중보험문제와 관련한 이상과 현실 사이에는 상당한 괴리가 있음을 발견하였다.
