What are the effects of life science teaching on the children's ability to discuss of the children's scientific investigation? The target groups of the study are a class of twelve children of 4 years old who are total 24 students of two different day care centers in Daejeon City. The children of the experimental group, A, in one daycare center have been instructed with the life science teaching for the science activity for 16 weeks, while the control group, B, in a different day care center, have been instructed the standard of child care process for the science activity. The measurement of young children's naturalist intelligence and scientific inquiring ability had been used 'the multiple intelligence test (PMIT-E) for preschoolers' and 'the testing instrument of scientific inquiring ability'. To know the difference of their naturalist intelligence between the experimental group and the control group, the research material collected through such a testing instrument had been verified the corresponding sample, t and to know the difference of their scientific inquiring ability, the significance had been verified through the application of ANCOVA. The crucial result on the study is as follows. Firstly, the children who were instructed with the life science teaching statistically significantly improved the young children's naturalist intelligence more than the children who were not instructed with the life science teaching. Therefore, life science teaching has a positive effect on improving young children's naturalist intelligence. Secondly, the result after the study is that the life science teaching has a considerable effect on scientific inquiring ability. The experimental child group experienced a significantly noticeable point increase statistically compared to that of the opposing group. Therefore, life science teaching has a positive effect on improving young children's scientific inquiring ability. Therefore, life science teaching has an effective class on young children's naturalist intelligence and scientific inquiring ability.

Objectives: Although there have been several reports that described characteristics for young age stroke, information regarding very young age (18–30 years old) has been limited. We aimed to analyze demographic factors, stroke subtype, and 3-month outcome in acute ischemic stroke patient who have relatively very young age in multicenter stroke registry. Methods: We evaluated all 122 (7.1%) consecutive acute ischemic stroke (within 7 days after symptom onset) patients aged 18 to 30 from 17,144 patients who registered in multicenter prospective stroke registry, 1997 to 2012. Etiology was classified by Trial of Org 10172 in Acute Stroke Treatment criteria. Stroke severity was defined as National Institutes of Health Stroke Scale (NIHSS) and stroke outcome was defined by modified Rankin scale (mRS) at 3 months after index stroke. Results: The mean age of all included patients was 25.1±3.7 years and 76 patients (62.2%) were male. The median NIHSS at admission was 4. Considering stroke subtype, 37 patients (30.3%) had stroke of other determined etiology (SOD), 37 (30.3%) had undetermined negative evaluation (UN) and 31 (25.4%) had cardioembolism (CE) were frequently noted. After adjusting age, sex and variables which had P<0.1 in univariable analysis (NIHSS and stroke subtype), CE stroke subtype (odds ratio, 4.68; 95% confidence interval, 1.42–15.48; P=0.011) were significantly associated with poor functional outcome (mRS≥3). Conclusion: In very young age ischemic stroke patients, SOD and UN stroke subtype were most common and CE stroke subtype was independently associated with poor discharge outcome.

우적가 배경설화에 나타난 시험과 오도의 양상

김영수(Kim Young-Soo) 비교민속학회 2003 비교민속학 Vol.25 No.-

While we read the old documentary records, what we should be careful about is that we should approach and analyze the real material through doubt if it has a non-logical structure. And we should avoid the way of blind following and accepting to the opinion that pre-researchers has given. Why I had interest in the myth of U-Juck-Ga(遇賊歌 : The song made by a monk 〈named Young-jae〉 of Sin-ra dynasty. Its title means the song when he met sixty bandits) was the point that the bandits reward giving the property. And at once they were very impressed after listening to the one song, and as soon as they listened to the song they turned into the buddhist. So it describes a happening like a miracle. So I think that we can't explain the identity of bandits and the meaning of song without solving this kind of strange and non-logical meaning. The background myth of U-Juck-Ga has the structure of the personal seeking after truth of monk named Young-jae(永才). The entering to mountain of the monk Young-jae has not the meaning of small hiding(小隱 : To hide somewhere like a mountain for seeking after truth 〈accompanying not so much pain or hardship〉)or big hiding(大隱 : To hide somewhere like a mountain for seeking after truth 〈accompanying very much pain or hardship〉) but almost like the meaning of being scattered hiding(散隱 : To hide like a person who doesn't exist for seeking the truth 〈accompanying extreme pain and hardship〉) as the classical scholar Huh-am(虛庵 : The title of Jung-hi-ryang〈鄭希良〉, one classical scholar of Cho-sun dynasty) appointed. We should regard him as not the monk who had fame and sang a song very well but the monk who tried to turn to buddha with his 90-year-old body. The fact that the monk Young-jae was quite good at making the Hyang-Ga(鄕歌 : a poem and song especially thrived in the period of unified Sin-ra dynasty) is just a little detail of describing about him. And we should regard that the bandits already knew the name of the monk as that the fame of the monk was already well-known to bandits. The reason why they let him to make the Hyang-ga is not because of his good talent to make it. That he was quite good at making Hyang-ga means that he had not only very high virtue but also had a good talent to persuade someone when he made Hyang-ga. As it were, it is not just a simple song but a song which is quite easy to be understood about the doctrine of buddhism. If the bandits let the 90-year-old monk sing a song just because he is good at singing a song, then it is just the behavior of making fun of him, and the fact that the bandits turned into the buddhist through the monk Young-jae can't not but to have a big contradiction. The identity of the bandits might reflect the hard time of that period, and also can be his spiritual enemy for testing his body and soul. As the U-Juck-Ga has the meaning of reflecting oneself on passed days, for the wandering bandits who had no fame the monk Young-jae could be the changed people of buddha. and In the aspect of Young-jae himself the identity of the bandits could be the changed people for testing his body and soul.

혈중 지질농도는 식이단백질 종류보다는 연령의 영향을 많이 받아, young군보다 old군의 총 콜레스테롤, TG, HDL-콜레스테롤, LDL+VLDL-콜레스테롤 및 AI 모두 높았다. 한편 콩 단백질군에서 HDL-콜레스테롤 수준이 증가하고, LDL+VLDL-콜레스테롤와 AI는 감소하여, 심혈관질환에 대한 콩 단백질의 유익한 효과를 확인할 수 있었다. 식이단백질에 의해 유의한 영향을 받은 혈장 인지질의 지방산조성중 22:0, 18:1ω9, ∑MUFA 조성은 카제인군에서 콩 단백질군 보다 높았으며, 반대로 ∑SFA 조성은 카제인군에서 낮았다. 연령에 의해 혈장 인지질 지방산 조성에 있어 유의한 차이를 보인 지방산 중 22:0, 18:1ω9, 22:1, 18:3ω3 및 22:4ω6는 young군에서 높은 반면에, 22:6ω3, ∑ω3, 18:2ω6, 20:4ω6, ∑ω6 및 ∑PUFA의 조성비율은 old군에서 높게 나타났다. 이와 같이 식이 단백질의 종류보다 연령의 영향력이 더 많이 나타난 것은 혈중 콜레스테롤 수준이 식이 단백질보다는 연령의 영향을 더 크게 받았기 때문으로 생각된다. 혈장 인지질 지방산의 대사지표 중 Δ7-desaturation index(16:0⇒16:1ω7)와 Δ9-desaturation index(18:0⇒18:1ω9)가 식이 단백질의 영향을 받아 카제인군에 비해 콩 단백질군에서 유의하게 낮았다. Δ7- 및 Δ9-desaturation index만이 식이 단백질의 영향을 받은 것은 식이 단백질보다 desaturase 활성에 더 큰 영향력을 미치는 콜레스테롤이 식이에 첨가되었기 때문이라 생각된다. Δ-4 desaturation index (22:4ω6⇒22:5ω6)는 young군에 비해 old군에서 높았으며, elongation index(20:4 ω6⇒22:4ω6)는 old군에서 낮았다. 대부분의 elongation과 desaturation 단계는 연령에 따라 유의한 차이를 보이지 못하였으나, ω3계 지방산의 전체적인 elongation-desaturation 단계를 나타내는 ∑products-fatty acid(ω3)/α-LNA(ω3) 비율이 old군에서 young군보다 유의하게 높아, 연령에 따른 PUFA 대사의 변화가 관찰되었다. 이상에서와 같이, 콩 단백질의 섭취로 흰쥐 혈장 인지질의 ∑MUFA 조성은 낮고 ∑SFA 조성은 높아 다른 지질 강화성분의 섭취와 유사한 결과를 나타내었다. 혈중 콜레스테롤 수준이 높은 old군에서 체내 막조직의 유동성을 유지하기 위해 PUFA의 합성 특히 ω3계 지방산의 elongation-desaturation이 증가하여 총 PUFA 조성이 young군보다 높았다. 연구결과로 이소플라본을 포함한 콩 단백질의 혈중 지질저하 기전에 대해 체계적인 설명은할 수 없지만, 콩 단백질이 혈장 지방산의 조성을 변화시킴으로써 간접적으로 심혈관계 질환에 대해 유익한 효과를 미침을 알 수 있었다. 한편, 이러한 혈관의 건강과 관련된 콩의 유익한 효과는 이소플라본과 같은 콩의 특정 성분의 단독효과라기보다는 콩 단백질과의 복합효과에 의한 것이라는 주장은 매우 설득력 있다고 생각된다. Effects of soy protein concentrate (SPC) containing isoflavone and casein diets on plasma phospholipid (PLs)-fatty acid patterns were investigated in 7- & 40- wk old female rats. Diets containing 16% SPC (soy/young: SY, soy/old: SO) and casein (casein/young: CY, casein/ old: CO) supplemented with 0.5% cholesterol were fed for 4 wks. Fatty acid compositions of plasma PLs were determined by TLC and GLC. Compared to the dietary protein effects, age effects on serum lipids were more profound. The levels of total cholesterol (Chol.), triglyceride, HDL-Chol., (LDL+VLDL)-Chol. and atherogenic index (AI) were higher in older groups (OC & OS) than younger groups (YC & YS). Soy groups had higher HDL-Chol. level and lower (LDL+VLDL)-Chol. and AI, compared with casein groups. The compositions of C22:0, C18:1ω9 and sum of MUFA in plasma PLs were significantly higher in casein group (CY & CO) than soy group (SY & SO), but those of sum of SFA were higher in soy group. The compositions of C22:0, C18:1ω9, C22:1, C18:3ω3 and C22:4ω6 were higher and those of C22:6ω3, sum ofω3, C18:2ω6 C20:4ω6, sum ofω6 and sum of PUFA were lower in plasma PLs of younger rats. The average P/S and ω3/ω6 ratio in older group was higher. The Δ-7 desaturation index (16:0⇒16:1ω7) and Δ-9 desaturation index (18:0⇒18 : 1ω9) were lower in soy group than casein group, while Δ-6 and Δ-5 desaturation index were not affected by dietary protein. The Δ-4 desaturation index (22:4ω6⇒22:5ω6) were higher and, elongation index (20:4ω6⇒22:4ω6) were lower in older group. The ratio of the products of ω3 fatty acid series/precursor of ω3 fatty acid series (C18:3) was significantly higher in older group, which in- dicated that age affected the plasma PUFA metabolism. On the other hand, older rats had higher serum cholesterol level compared with younger rats. Taken together, these changes in fatty acid composition might cause minimal changes in the membrane fluidity induced by the increase serum cholesterol level.

THE EVALUATION OF HYDRAULIC CHARACTERISTICS OF THE GEOSYNTHETIC CLAY LINERS WITH HUMIC SUBSTANCES OF LEACHATE IN THE LANDFILL

( Young-soo Han ),( Jai-young Lee ) 한국폐기물자원순환학회 2002 APLAS Vol.2002 No.1

Geosynthetic clay liners (GCLs) have widely used as one of the hydraulic barrier materials in waste landfills; however, they also have a potential danger when exposed to some organic and inorganic leachate. The major component of the GCLs is bentonite. Hydraulic conductivity of GCLs can be easily changed due to bentonite, if they are permeated with various components of the leachate. Especially, the humic materials of landfill lechate closely interact with clay particles in bentonite. This study was performed to characterize the humic materials composed of two kinds of landfill leachate; the first one was a leachate of old-landfill (O-landfill) and the other one was a leachate of young-landfill (Y- landfill). Also,another purpose was to evaluate the effect of humic materials on the swelling and hydraulic conductivity of GCLs. The result of the swelling tests showed that the amount of humic materials and high electrical conductivity caused a decrease of the swelling of bentonite. This was expected to increase the hydraulic characteristics of GCLs. The increase in hydraulic conductivity of GCLs permeated with O-leachate was significantly higher than that with Y-leachate. This trend showed that humic materials were responsible for the increase in hydraulic conductivity of GCLs. Therefore, the potential danger of increasing hydraulic conductivity of GCLs permeated with the landfill leachate has to be considered when GCLs are used in waste landfills.

김영수,오성훈,박형천,정태섭 대한신경외과학회 1988 Journal of Korean neurosurgical society Vol.17 No.5

The bony spur formation without degenerative change in the lumbar spines in the young age group is quite interesting and is not uncommon. This bony spur is different from the degenerative spur in the old age group in shape and mechanism of formation. The authors analyzed 25 patients below 29 years old with such posterior lumbar bony spur. We concluded that posterioly lacated Schmorl's node is main cause of the bony pour in young age group at lumbar region.

A simple approach to estimate the mechanical properties of collagen-like microfibrils surrounded by water

Young-june Yoon,Cheol-soo Bae,Ho-sik Park 한국멀티미디어학회 2010 한국멀티미디어학회 국제학술대회 Vol.2010 No.-

The effective Young's modulus of a microfibril surrounded by water may be simply calculated by using the upper (Voigt) and lower (Reuss) bounds. The result is compared to the Young's modulus estimated by using the Steered Molecular Dynamics (SMD) (Zhang et al. 2007). Our result shows 9.2% difference from the result estimated by SMD, but the steps using these bounds are much simpler than SMD..
