These studies were carried out (1) to investigate the growth characteristics of Sedum album L. in the field, (2) to propose a suitable shallow peen roof system for this plant, and (3) to evaluate plant growth in the proposed system over the long term. The growth characteristics, such as morphological properties, growth habit, shade tolerance, and flowering, were surveyed. In experimental shallow green-roof systems, the effects of drainage type, substrate type, and soil depth on plant growth were investigated. Then drought tolerance was investigated. After planting Sedum album L. in the proposed system survival rate, cover, and resistance to insects, heal and cold were evaluated for about 2 years. The results of these studies are summarized below. 1. In the field, the aboveground part of Sedum album L. did not die back during the winter. Plant height was 4$\sim$7 cm. Roots were distributed to a depth of 5$\sim$7 cm. Sedum album L. is a compact ground-cover plant that spreads vigorously. Shading condition of less than $30\%$ of full sunlight didn't cause any trouble, but shading conditions above $87\%$ made the shape of the shoots and leaves abnormal. The plant bloomed from June to August and had a rather large compound umbel of white, star-shaped flowers. 2. Two systems, a drainage-blend-10 cm soil depth and a reservoir$\cdot$drainage-blend-15 cm soil depth, performed best in terms of cover, fresh weight, and dry weight. The first has an advantage for green roofs because it is lighter than the latter. 3. In drainage-blend-10 m soil depth and modified reservoir · drainage-blend-10 cm soil depth system no plants died for about 4 months after stopping the irrigation. The visual quality of the latter system was above 5 for 4 months and that of the former was under 5 after 2 months. In the field, however, the drought tolerance of Sedum album L. grown in the former would be enough to withstand the dry season. Considering the urban ecosystem and the importance of healthy growth the modified reservoir $\cdot$ drainage-blend-10 cm soil depth system was finally recommended. This system was composed of a 4 cm thick drainage layer and drain outlets placed at a height of 2.5 cm. 4. In the proposed system, the survival rate was $100\%$, and there was no injury induced by insects and heat. The leaf density decreased a little in winter. Cover increased throughout the year. Sedum album L. was planted with a cover of 72$cm^{2}$ on 3 April 2003; on 16 June 2003 and 15 June 2004, cover was $132.66\pm$5.87 $cm^{2}$(1.8 times) and $886.98\pm$63.51 $cm^{2}$(12.3 times), respectively.

미드라쉬의 성서교수학적 함의와 적용

김인혜,고원석,Kim, In Hye,Koh, Won Seok 한국기독교교육학회 2021 기독교교육논총 Vol.- No.67

본 논문은 시대적 상황 속에서 성서교육에 대한 새 패러다임을 모색하며 유대 성서해석의 옛 전통인 미드라쉬로 시선을 돌린다. 이는 오늘의 상황 속에서 현재의 성서교육이 의미 있고 효과적인 교육이 되기 위한 준거틀을 삼고자 함이다. 유대 랍비들은 성경을 대할 때 특정한 해석지침을 가지고 있었는데, 이러한 해석지침은 미드라쉬와 함께 전수되었으며, 성경을 해석하는 태도를 형성하였다. 미드라쉬는 문집이나 강론 모음집, 랍비 문학의 특정 장르, 공개적으로 전달되는 성경 주석과 설교, 그리고 성경의 특정 책에 대한 주석 행위 등을 포함하는 상당히 넓은 의미지평을 가지고 있다. 랍비들의 미드라쉬 해석지침은 성경이 들음과 배움의 자세를 요청하고 탐구의 자세를 갖게 한다는 것, 여백을 통한 탐구를 하고자 하며 상호존중과 상호소통의 중요성을 알게 하고, 오늘 나에게 도전하는 말씀이라는 성서교수학적 의미를 발견하게 한다. 한편 미드라쉬를 성서교수학적으로 적용한 비블리오드라마는 미드라쉬의 해석지침과 많은 공유점을 갖고 있다. 비블리오드라마는 성경과 참여자의 대면을 통해 서로 인격적인 만남과 성찰을 일으킴으로써 서로를 새로운 모습으로 발견하는 기회를 제공한다. 그리하여 비블리오드라마는 성경의 내용을 바르게 이해하고 인식하는데 그치는 것이 아니라 그 이해와 인식을 바탕으로 참여자의 삶에 도전하고 새로운 관점으로 참여자 자신의 삶을 돌아보게 함으로써 새로운 정체성 형성을 도모한다. The purpose of this study is to explore a new paradigm for Bible didactics in the context of the contemporary times and it turns its gaze to the midrash, the old tradition of Hebrew Bible interpretation. In order for the current Bible study to be meaningful and effective in today's situation, it is an effort to connect the Bible and us well, more than educational contents or materials. The word "midrash" itself means "textual interpretation", or "study", derived from the root verb darash, which means "to seek," "to seek with care," "to enquire," "to require" forms of which appear frequently in the Hebrew Bible. Midrash means an exegesis and interpretation of the Hebrew Bible (Torah) as well as a group of works that are the result of specific interpretations of the rabbis. This rabbinical tradition provides specific interpretative guidelines dealing with the Bible. These interpretive guidelines were passed down and formed an attitude of interpreting the Bible that is still relevant today. The rabbinical interpretative guidelines in midrash lead to the discovery of the following biblical didactical meanings. First, the Bible requires an attitude of listening and learning. Second, an attitude of inquiry is needed. Third, an exploration through the empty space is essential. Fourth, it leads us to recognize the importance of mutual respect and communication. Fifth, through the Words that challenge me, the meaning of biblical teaching is discovered. These interpretation guidelines have much in common with Bibliodrama, which applies midrash to the didactic of Bible. Bibliodrama is a dramatic inquiry, where the effect of in-depth inquiry and consideration that midrash aimed at can be expected. In addition, bibliodrama is a process of communal interaction that leads to a new experience and a richer understanding of the Bible through different positions and viewpoints. Exploring the "white fire" of the Bible, we listen to what God says to us, which causes us to change and form an identity. The biblical didactical meaning found in midrash's interpretation guidelines and the biblical didactical application of midrash through the bibliodrama can be presented as a new alternative to Christian education for the past, the present and the future. This will be able to present a new paradigm for biblical didactics with the word of God living and working in the present, not the Bible of the past, which is far from our present life.

김인혜,남택정,Kim In-Hye,Nam Taek-Jeong 한국생명과학회 2005 생명과학회지 Vol.15 No.6

본 연구는 whole molecular-, 40 kDa-, 10 kDa poly-mannuronate를 대장암세포에 첨가하였을 때 분자량과 농도 에 따른 항암효과를 세포수준에서 검토하고자 하였다. 3종류의 인체 대장암세포인 HT-29, DLD-1, WiDr의 증식 억제를 살펴본 결과, HT-29 세포는 모든 polymannuronate $0.25\%$의 농도에서 $50\%$의 증식 억제 효과를 보였으며 저분자화 될 수 록 증식 억제 효과가 증가되었다. DLD-1 세포는 저분자화 정도와 농도증가에 따른 유의적인 차이를 보이지 않았고, WiDr 세포는 농도증가에 따른 유의적인 효과는 있었으나, 분자량에 의한 차이는 보이지 않았다. $0.25\%$의 농도에서 $50\%$의 증식 억제 효과를 보인 HT-29 세포의 DNA 합성능을 살펴본 결과, 증식 억제 효과와 유사한 결과를 보였으며, 형태학적인 변화 또한 동일한 것으로 나타났다. 이상의 결과로부터 polymannuronate는 HT-29 대장암세포의 증식억제에 유의적인 효과가 있는 것으로 나타났다. 따라서 polymannuronate는 대장암의 예방뿐 아니라 그 치료에도 도움이 되며 본 연구가 polymannuronate의 효과에 대한 기초적인 자료가 될 것으로 사료된다. This study investigated the proliferation and DNA synthesis inhibitory effect of concentrations ($0.01\%$, $0.1\%$, $0.25\%$, $0.5\%$) when added whole molecular-, 40 kDa-, or 10 kDa polymannuronate on human colon cancer cells, HT-29, DLD-1, and WiDr, in vitro. In order to determine the proliferation inhibitory effect of low-molecularized polymannuronate, the treatment of whole molecular-, 40 kDa-, 10 kDa-, polymannuronate ($0.25\%$) to the HT-29 cancer cells inhibited proliferation of cancer cells by $41\%$, $69.1\%$, and $75.6\%$, respectively. DLD-1 cancer cell was not relation of molecular weight and concentration. WiDr cancer cell depend on concentration without molecular weight. In addition, whole molecular-, 40 kDa-, 10 kDa poly mannuronate ($0.25\%$) significantly inhibited DNA synthesis of HT-29 cancer .cells by $78\%$, $58\%$, and $56\%$, respectively. And morphological changes not found under microscope by polymannuronate. Therefore polymannuronate would be helpful to colon cancer treatment as well as cancer prevention and this study would be the basic source for further research of polymannuronate.

김인혜(In Hye Kim),박정옥(Jung Ok Park),최문경(Moon Kyung Choi) 한국영재학회 2006 영재교육연구 Vol.16 No.1

이 연구의 목적은 1990년 1월부터 2003년 12월까지 국내 주요일간지에 게재된 영재교육 관련 기사의 양과 내용을 분석함으로써 시대에 따른 영재교육의 사회적 인식과 경향을 살 펴보기 위한 것이다. 연구대상의 기간은 3기로 나누었고, 관련기사의 내용은 영재교육의 동 향, 영재교육 정책 , 영재교육 정보, 사회 환경으로 분류하여 분석하였다. 분석 결과 영재교육 관련 기사의 양은 시기별로 꾸준히 증가하였고, 특히 2000년 영재교 육진흥법 제정이후에 큰 폭의 증가를 나타내었다. 이를 통해 영재교육이 정착화 됨에 따라 영재교육 관련기사도 점차 영재교육 전반에 걸쳐 큰 폭으로 다루어지고 있음을 알 수 있다. 또한 영재교육 관련 기사의 내용에 있어서는 1기에는 체제와 제도에 관련된 기사가, 2기 와 3기에는 영재교육기관에 관한 기사가 많았다. 이는 1기에는 영재교육에 대한 여러 논의 를 통해 영재교육의 필요성에 대한 인식 정착되었고, 2기와 3기에 영재교육에 대한 제도화 가 이루어지면서 영재교육 기관에 대한 관심이 커졌음을 알 수 있다. The object of this research is to analyze the contents and amount of articles on gifted education in major daily newspapers dated January 1990 to December 2003, and to review the trend of social perception of gifted education with the passage of time. Following are the research question : 1. How many articles belonging to the same category appeared in the newspapers within the period of time covered by the study? 2. What kinds of articles appeared in the newspapers within the period of time covered by the study? To arrive at the answers to the problems mentioned above, 714 articles on gifted education. The period from 1990 to 2003 were divided into time frames of 5 years to facilitate the analysis of social consciousness regarding gifted education before and after the enforcement of the Early School Entering Law in 1995 and the Law for Promotion of Gifted Education in 2000. The researcher defined Period I as the years from 1990 to 1994, Period II from 1995 to 1999, and Period III from 2000 to 2003. The articles were classified by content which were significance and trend of gifted education, current policies on gifted education, information on gifted education, and social environment of gifted education. The results of the analysis are as follows: (1) The articles from 1990 to 2003 totalled 714. 130 articles were found within Period I, 213 within Period II, and 371 within Period III. Since the year 2000, when the Law for Promotion of gifted education was enforced, the amount of articles considerably increased. The articles on the trend of gifted education numbered 42 within Period I, 49 within Period II, and 81 within Period III, showing a huge increase in the last period. The articles on current policies numbered 56 within Period I, 77 within Period II, and 143 within Period III, numbering the most in the last period. This means that, even before the Law for Promotion of gifted education was enforced, there has been much interest in and discussion of the appropriate educational system for gifted children in preparation for the legal and institutional foundation of such system. Since the enforcement of the law, many institutions were established and the problem became an important social issue. The articles that most frequently appeared were about current policies on and status of gifted education. This category showed the largest numbers through all the three periods and on all the subjects. This subject represented 43.1% of the articles on gifted children within Period I, 36.2% within Period II, and 38.6% within Period III. As to the significance and trend of gifted education, this subject showed a decrease from 32.3% within Period I, 23% within Period II, and 21.8% within Period III. However, the articles in the category of information on gifted education gradually increased from they represented 5.4% of the articles on brilliant children within Period I, 7.5% within Period II, and 8.4% within Period III. The social environment articles showed an increase from Period I to Period II-- from 19.2% to 33.3%, but it went down to 31.3% within Period III. (2) As to articles on the trend of gifted education, there were many such articles found, mainly on researches and trends in other countries. As greater importance is accorded to gifted children and as the recognition of the necessity of providing specific education for them grows, more related studies are conducted and people try to adopt new trends from other countries. For the articles on the current policies of gifted education, most of them were about institutions. This means that many educational institutions have been established since the Law for Promotion of Gifted Education was enforced. Informative articles on gifted education were mostly about distinctive features of gifted children and how to tell who the brilliant children are. This fact shows the importance of identifying gifted children in order to educate them systemically and effectively. It likewise shows that

사람의 섬유아세포에서 glucose 농도가 물질대사 및 Insulin-like growth factor binding protein-3의 발현에 미치는 영향

류혜영,황혜정,김인혜,류홍수,남택정,Ryu, Hye-Young,Hwang, Hye-Jung,Kim, In-Hye,Ryu, Hong-Soo,Nam, Taek-Jeong 한국생명과학회 2007 생명과학회지 Vol.17 No.5

사람의 섬유아세포인 GM10을 사용하여 glucose의 배양조건에 다른 물질대사 및 IGFBP-3 발현을 살펴본 결과, glucose 농도에 따른 glucose 소비와 triglyceride 축적 수준은 고농도 glucose 배양 조건에서 증가한 반면, 총 단백질 함량은 고농도 glucose배양 조건에서 시간의 경과에 따라 감소하였다. 또한 고농도 glucose 배양 조건에서 5일 동안 배양한 세포 배양액내의 유리아미노산 함량은 저농도보다 고농도 glucose 배양 조건에서 높게 나타났다. IGFBP-3 단백질 수준과 mRNA수준은 저농도 glucose배양 조건에서 증가하였으나, IGFBP-3 단백질 분해효소에 따른 영향은 없었다. 이상의 결과에서 glucose 배양조건에 따른 물질대사는 부분적으로 세포를 이용한 당뇨병 모델 실험에서 in vivo와 같은 결과를 얻지 못하였지만, IGFs와 같은 세포 성장인자에 대한 연구를 통해 세포수준의 당뇨병 모델화가 가능하다고 여겨진다. Insulin-like growth factor-I(IGF-I) has significant insulin-like anabolic effects which include the stimulation of glucose and amino acid uptake, as well as protein and glycogen synthesis. IGFs exist in serum and other biological fluids as complexes bound to a family of structurally related insulin-like growth factor binding proteins(IGFBPs). Six human IGFBPs can modulate the effects of IGFs on target tissues by several mechanisms, including altering the serum's half-life and the transcapillary transport of IGFs, as well as changing the availability of IGFs to specific cell surface receptors. Human fibroblasts secrete IGFBPs that can modify IGF-I action. Previous to our study using either Northern blotting, and Western blotting have shown that fibroblasts express mRNA IGFBP-3, -4, and -5, and synthesize these proteins. In addition, fibroblast cell lysates revealed that the IGFBP-3 was most abundant. For these reasons, we undertook to gain further insight into the effects of high and low glucose incubation condition on metabolism and IGFBP-3 expression. In results of metabolites and IGFBP-3 expression in GM10 cells cultivated with various glucose concentration, the consumption of glucose and accumulation of triglyceride were increased in condition of high glucose, and total protein level was decreased. in the course of time. After 5 days incubation, levels of free amino acid in medium containing glucose of high concentration glucose were higher than in conditions of low glucose. Although the levels of IGFBP-3 protein and mRNA levels were increased in low glucose, and IGFBP-3 was not affected by any pretense. Taken together, we suggest that the study of growth factors, like IGFs, might be a possible model of diabetes militus in cell, although the results in cell models were not in accord with in vivo.

사람의 섬유아세포에서 Glucose 농도가 Insulin-like Growth Factor Binding Protein-5의 발현에 미치는 영향

류혜영,황혜정,김인혜,류홍수,남택정,Ryu, Hye-Young,Hwang, Hye-Jung,Kim, In-Hye,Ryu, Hong-Soo,Nam, Taek-Jeong 한국생명과학회 2007 생명과학회지 Vol.17 No.9

사람의 섬유아세포인 GM10에서 glucose 농도에 따른 IGFBP-5의 존재와 발현에 미치는 영향을 살펴보고 당뇨병과 관련된 in vitro model system으로서의 활용 가능성을 검토하고자 하였다. 섬유아세포인 GM10 세포를 시용하여 glu-cose 배양 조건에 따른 IGFBP-5의 존재와 발현에 미치는 영향을 살펴보았다. 그 결과, IGFBP-5의 단백질 수준은 고농도 glucose 배양 조건에서 증가하였으나, IGFBP-5 mRNA 발현에는 아무런 영향을 나타내지 않았다. IGFBP-5 protease 활성은 고농도 glucose 배양 조건에서 높았다. IGF- I 과 인슐 린은 IGFBP-5 protease 활성에 관여하는 것으로 보여지며, GM10 세포에 있어서 IGFBP-5의 분해에는 serine protease 뿐만 아니라 metalloprotease가 관여하는 것으로 나타났다. 또한, gelatin zymography를 통한 protease 활성은 고농도 glucose 배양 조건에서 크게 나타났으며, 시간 의존적으로 증가하였다. 본 연구 결과를 바탕으로 IGFs와 같은 세포 성장인자에 대한 연구는 세포수준의 당뇨병과 관련된 in vitro model system이 가능하리라고 여겨지며 더 많은 연구가 진행되어야 할 것으로 보인다. Insulin-like growth factor-I (IGF-I) and IGF-II have structure like insulin. In contrast to insulin, however, the bioavaility of IGFs is modulated by the IGF-binding protein (IGFBPs). Each of IGFBPs was different with molecular masses, biological characteristics, and immunological properties.. Human fibroblasts secrete IGFBPs that can modify IGF-I action. In diabetes mellitus, the most study of IGF systems have been investigated in insulin-dependent diabetes mellitus, non-insulin-dependent diabetes mellitus, and streptozotocin-in-duced animals in vivo. Recently, a little research regarding the IGFs system has been proposed in por-tion of cell in vitro. In this study, effects of low or high glucose condition on IGFBP-5 in GM10 was investigated. By western blotting analysis, IGFBP-5 level decreased in cells cultured at high glucose, but IGFBP-5 level of mRNA didn't change. IGFBP-5 protease that cleaves IGFBP-5 in conditioned me-dium had was inhibited by EDTA and heparin, like serine protease and metalloprotease. Furthermore, the protease activity was increased in high glucose cultivated condition. In results of gelatin zymog-raphy, molecular weight of proteolytic metalloenzymes was indentified 69-kDa and protease activity was increased in time-dependent manner. Although the mechanism has yet to be determined, IGFBP-5 proteolysis in GM10 cells cultured with high glucose may increase effects of IGFs to decrease the glu-cose level through dissociation of IGFs from IGFBPs. Therefore, we suggest that IGF- I and IGFBPs could be potential models in study of pathophysiology such as diabetes mellitus.

The brown alga Saccharina japonica is consumed as a foodstuff in many countries. Carbon tetrachloride (CCI4) is a potent hepatotoxin that is used to assess hepatotoxicity in animal models. This study assessed the protective effect of S.japonica extract (SJE) on CCl4-induced acute liver injury in rats. Experimental rats were divided into the following three groups: control, CCI4, and CCI4 +SJE; the latter two groups were given 150 or 300 mg SJE/kg orally for 10 days. Three hours after the final treatment all rats-except for those in the control group-were administered intraperitoneal injections ofCC14 · One day later blood and liver samples were collected for evaluation biomarker of levels. Aspartate transaminase (APT; GPT) and alanine aminotransferase (ALT; GOT) levels were markedly lower in the CCI4+SJE group than the CCl4 group. The hepatic superoxide dismutase (SOD) activity of the CCI4+SJE group was significantly lower than that of the CCl4 group. In comparison, glutathione S-transferase (GSH) and catalase (CAT) levels were significantly higher in the CCI4+SJE group. Western blotting revealed that SJE attenuated the CCl4-ioduced EGFR and MAPK activity in the liver. Thus, we conclude that SJE protects against CCl4-induced hepatotoxicity.

This study was conducted to examine the interaction patterns of high school students in online debate and to find ways to activate them. An online discussion was conducted for 3rd grade high school students, and data was measured based on the direction and number of comments. Using NetData, igraph, and ggplot2 of the R package, the number and density of the connect line, the Degree centrality, Betweenness centrality, Eigenvector centrality were measured, and interaction patterns were derived through visualization work. Through density, the degree of interaction of the group was checked, and the number of comments and the participation of all members were confirmed to be affected. Participants with a high Degree centrality of connection had a higher Degree centrality in sending and a high rate of rebuttal of comments. It was confirmed that Betweenness centrality and Eigenvector centrality influenced the interaction of all members. Based on this, it suggested the need for learning to clarify and refute the conditions of online debate as a way to promote online debate among high school students.

Polymannuronate가 흰쥐의 간장조직과 분변 중의 콜레스테롤 함량에 미치는 영향

김인혜(In-Hye Kim),남택정(Taek-Jeong Nam) 한국식품영양과학회 2005 한국식품영양과학회지 Vol.34 No.10

Polymannuronate를 첨가한 사료를 흰쥐에 각각 기초식이군, 콜레스테롤식이군과 5% polymannuronate가 함유된 콜레스테롤식이군을 4주간 급이한 후 혈청, 간장조직 및 분변에 미치는 영향을 살펴보았다. 콜레스테롤식이군에 비해 polymannuronate식이군에서는 혈청 및 간장조직의 총콜레스테롤 함량이 유의적으로 감소하였으며, 간장조직 중의 지방분포도 동일한 경향을 보였다. Polymannuronate식이군은 콜레스테롤식이군보다 일일 분변량이 유의적으로 증가하였는데, polymannuronate가 담즙산 및 콜레스테롤과 결합하여 분변으로 배출되어 분변 중의 총담즙산과 총콜레스테롤 및 총식이섬유 함량이 증가한 것으로 보여진다. 이상의 결과에서, polymannuronate는 체내에서 담즙산 및 총콜레스테롤과 결합하여 분변 중으로 배출함으로써 흰쥐의 혈청 및 간장조직 중의 총콜레스테롤 함량을 감소시켜 지질개선의 효과를 나타내는 것으로 보여진다. This study investigated the effects of polymannuronate feeding on cholesterol levels of serum, liver tissue, and feces in rats. After one week of general diet feeding, four week old S.D. rats were fed basal diet group, cholesterol diet group (1% cholesterol), and polymannuronate diet group (1% cholesterol, 5% polymannuronate). The total cholesterol levels in the serum and liver tissue was significantly decreased in the polymannuronate diet group. The polymannuronate diet group showed increased amounts of feces, total fecal bile acid and dietary fiber contents compared to basal diet group and cholesterol diet groups. Also, the histology of liver showed serious localized fat drops in the cholesterol diet group, but the polymannuronate diet group showed fewer localized fat drops. These results suggest that feeding of polymannuronate improves the lipid metabolism profile of rats by changing the serum and liver tissue cholesterol levels with increased level of the total bile acid, total dietary fiber and total cholesterol level in the feces.

Hypoglossal schwannomas are very rare. These tumors usually originate intracranially, sometimes extend extracranially. Isolated extracranial tumors extremely rare. Surgical approach of hypoglossal schwannomas are variable and surgeon should choose appropriate method considering location of main tumor. The authors experienced and treated a 55 year-old male patient with an isolated extracranial hypoglossal schwannoma extending into the parapharyngeal space. The tumor was removed successfully through modified transcervical approach. We report this case with relevant review of literature.
