  • The purpose of this study were to find out the practical way to enlarged child-raising knowledge and to enhance their satisfaction with out-patient care by evaluating how effectively the education is done by nurses for mothers with ill-child and how their satisfaction with out-patient care changed. This study was designed as a Nonequivalent Control Group study. The subjects studied were consisted of the experimental and control group. Each consisted of 50 mothers with ill-child in pediatric department at one university hospital in Seoul. The period of this study is from May 20, 1996 to J one 28, 1996. The first data were collected from both of experimental and control groups in which mothers with ill-child come to the hospital for the first time. After this being done, the experimental group had been educated by the planned program and then the second data were collected from them. On the contrary, as for the control group, there had been no education and the second data were col looted on the same method. The data analysis was done by SPSS program. The results of this study are as follow, 1 The child-raising knowledge level of mothers with education was higher than that of with no education. (t=18.84, df=49, p=0.000) 2. The satisfaction with out-patient care level of mothers with education was higher than that of no education. (t=10.51, df=49, p=0.000) Based on these results, I suggest as follow, 1. The research on the patients and their family should be made not only in pediatric department, but in every out-patient department. 2. For more effective education, it is required for all out-patient nurses to research the education demand of patients and their family. 3. To increase the effect of education, there must be the consultation room in out-patient department. 4. The meetings with the mothers with ill-child of the same illness have to be established and periodical education must be executed. 5. Audio-visual education programs like video tapes are needed to make use of waiting time for the medical treatment. 6. On-line consulting programs are needed.

  • In November 2008, typical powdery mildew symptoms were observed on leaves of Arabidopsis thaliana ecotype Col-0 plants in a growth room under controlled laboratory conditions at Korea University, Seoul. The disease was characterized by the appearance of white powder-like fungal growth on the surface of infected leaves. As the disease progressed, infected leaves exhibited chlorotic or necrotic brown lesions, and leaf distortion and senescence. Conidiophores of the causal fungus were hyaline, unbranched, 3-4 celled, cylindrical, and $80-115{\times}6-9{\mu}m$ in size. Singly produced conidia (pseudoidium type) were hyaline, oblong to cylindrical or oval in shape, and $26-55{\times}15-20{\mu}m$ in size with a length/width ratio of average 3, angular/rectangular wrinkling of outer wall and no distinct fibrosin bodies. Appressoria on the hyphae were multi-lobed. These structures are typical of the powdery mildew Oidium subgenus Pseudoidium, anamorph of the genus Erysiphe. The measurements of the fungal structures coincided with those of Erysiphe cruciferarum. The phylogenetic analysis using ITS rDNA sequences revealed that the causal fungus Erysiphe sp. KUS-F23994 is identical to E. cruciferarum. The isolated fungus incited powdery mildew symptoms on the inoculated Arabidopsis leaves, which proved Koch's postulates. Taken all data together, we first report the occurrence of powdery mildew disease of A. thaliana caused by Erysiphe cruciferarum in Korea.

  • Objectives : Recently, numerous studies reported that excessive generation of advanced glycation end products (AGEs) stimulated expression of skin wrinkle related proteins. This study aimed to evaluate inhibits skin wrinkle formation effect of Mori Folium (MF) through decreased AGEs. Methods : To evaluate the skin wrinkle inhibition effect of MF, SD-rats were divided into three groups; normal rats (Nor), AGEs-induced rats (Con), AGEs-induce rats treated with MF at dose of 100mg/kg body weight (MF). To induced AGEs, streptozotocin (50mg/kg) was injected intraperitoneally, and after 3 days, 100mM methyl glyoxal was administered orally for 3 weeks. After the experiment, the animal's dorsal skin tissues and serum were separated and tested. Results : The oral administration of MF suppressed the AGEs level in serum. Also, the AGEs in skin tissues was significantly reduced through treatment of MF compared with control group. Moreover, the expressions of AGEs related proteins such as polyclonal anti-$N^e$-(carboxymethyl) lysine (CML), anti-$N^e$-(carboxyethyl)lysine (CEL), AGE receptors (RAGE) were reduced in MF group compared with the control group in kidney and skin tissues. The matrix metallo proteinase-1 (MMP-1) reduced by MF treatment with the result that collagen type 1 alpha 2 (COL1A2) was improved that reduced by accumulation of AGEs. Conclusion : The evidence of this study indicate that oral administration of MF reduces the levels of AGEs in serum, skin, and kidney tissues. In conclusion, MF inhibit skin wrinkle formation, suggesting the potential of anti-wrinkle material.

  • Objectives: Trans-cinnamaldehyde (TCA) is the main component of Cinnamomi Ramulus and it has been reported that TCA inhibits inflammatory responses in various cell types. Inflammation-mediated neurological disorders induce the activation of macrophages such as microglia in brain, and these activated macrophages release various inflammation-related molecules, which can be neurotoxic if overproduced. In this study, we evaluated gene expression profiles using gene chip microarrays in lipopolysaccharide (LPS)-stimulated BV-2 cells to investigate the antiinflammatory effect of TCA on inflammatory responses in brain microglia. Methods: A negative control group was cultured in normal medium and a positive control group was stimulated with $1{\mu}g/ml$ in the absence of TCA. TCA group was pretreated with $10{\mu}g/ml$ before $1{\mu}g/ml$ LPS stimulation. The oligonucleotide microarray analysis was performed to obtain the expression profiles of 28,853 genes using gene chip mouse gene 1.0 ST array in this study. Results: In positive control group, 1522 probe sets were up-regulated in the condition of the cutoff value of 1.5-fold change and 341 genes with Unigene ID were retrieved. In TCA group, 590 probe sets were down-regulated from among 1522 probe sets and 33 genes with Unigene ID were retrieved, which included 6 inflammation-related genes. We found out that Id3 gene is associated with transforming growth factor-${\beta}$ (TGF-${\beta}$) signaling pathway and Klra8 gene is related to natural killer cell-mediated cytotoxicity pathway. Conclusions: The results mean that TCA inhibits inflammatory responses through down-regulating the expressions of inflammation-related genes in LPS-stimulated BV-2 cells.

  • Objectives : Collagen decrease of Skin appears through various path ways. One of causes may be the Advanced glycation endproducts (AGEs) that combine formation of glucose and protein. The aim of this study was to explore the prevent wrinkle formation of Paeoniae radix (PR) and heated Paeoniae radix (HPR) via AGEs path way. Methods : AGEs formation inhibitory activities of PR and HPR measured using bovine serum albumin, glucose, and fructose. To evaluate the protective effects of PR and HPR in diabetic rats induced with streptozotocin (STZ) and methyl glyoxal (MGO), SD rat were distributed into four groups. Normal rats (Nor), AGEs-induced rats (Con), AGEs-induced rats treated with 100 mg/kg PR(PR), AGEs-induced rats treated with 100 mg/kg HPR (HPR). To induce AGEs, streptozotocin (50 mg/kg) was administered intraperitoneally and after 3 days administrated 100mM methyl glyoxal for 3 weeks. Results : The oral administration of HPR inhibited AGEs in skin tissues compared with PR. The increased reactive oxygen species (ROS) levels in the serum were diminished by HPR treatment. The analyses of kidney and skin tissues proteins indicated that HPR treatment effectively reduced AGEs related protein levels as compared to that by PR treatment. Also, HPR decreased anti-oxidant related protein levels in skin tissues such as catalase, glutathione peroxidase. Moreover, it inhibited the reduction of COL1A2 by decreasing MMP-1. Conclusion : Based on these results, it was suggested that PR and HPR could have Improving effects on wrinkle formation. These evidences provide useful information for the development wrinkle formation treated agent.

  • For the regeneration of periodontal tissues, the microenvironment for new attachment of connective tissue fibers should be provided, At this point of view, cementum formation in root surface plays a key role for this new attachment. This study was performed to figure out which factor promotes differentiation of cementoblast Considering anatomical structure of tooth, we selected the cells which may affect the differentiation of cementoblast - Ameloblast, OD11&MDPC23 for odontoblasts, NIH3T3 for fibroblsts and MG63 for osteoblasts. And OCCM30 was selected for cementoblast cell line. Then, the cell lines were cultured respectively and transferred the conditioned media to OCCM30. To evaluate the result, Alizarin red S stain was proceeded for evaluation of mineralization. The subjected mRNA genes are bone sialoprotein(BSP), alkaline phosphate(ALP) , osteocalcin(OC), type I collagen(Col I), osteonectin(SPARC ; secreted protein acidic and rich in cysteine). Expression of the gene were analysed by RT-PCR, The results were as follows: 1. For alizarin red S staining, control OCCM30 didn't show any mineralized red nodules until 14 days. But red nodules started to appear from about 4 days in MDPC-OCCM30 & OD11-OCCM30. 2. For results of RT-PCR, ESP mRNAs of control-OCCM30 and others were expressed from 14 days, but in MDPC23-OCCM30 & OD11-OCCM30 from 4 days. Like this, the gene expression of MDPC23-OCCM30 & OD11-OCCM30 were detected much earlier than others. 3. For confirmation of odontoblast effect on cementoblast, conditioned media of osteoblasts(MG63) which is mineralized by producing matrix vesicles didn't affect on the mineralized nodule formation of cementoblasts(OCCM30). This suggest the possibility that cementoblast mineralization is regulated by specific factor in dentin matrix protein rather than matrix vesicles. Therefore, we proved that the dentin/odontoblast promotes differentiation/mineralization of cementoblasts. This new approach might hole promise as diverse possibilities for the regeneration of tissues after periodontal disease.

  • 근래의 ABB/CE형 가압경수로들은, 정상운전 및 예상운전과도상태 중에 허용핵연료설계제한치가 위배되는 것을 방지하기 위하여, 노심 운전상태를 감시하는 디지탈노심감시계통, COLSS(Core Oper-ating Limit Supervisory System)를 보유하고있다. COLSS의 주요 기능 중 하나는. 측정되는 운전조건에 대한 최소 핵비등이탈률을 계산하여, 핵비등이탈에 대한 과출력여유도를 감시하는 것이다. COL-SS에서 최소 핵비등이탈률을 계산하는데 사용되는 CETOP-D 모델은 상세부수로분석코드인 TORC 모델에 대해 보수적으로 벤치마킹되며, 보정상수로서 고온집 합체의 입구유량인자를 사용하고 있다. 본 연구에서는 CETOP-D 입구유량인자를 가장 제한적인 운전조건에서 보수적인 단일 값으로 결정하는 ABB/CE 방법을 배제하고, 운전조건에 따른 CETOP-D 입구유량인자 변화를 상관식형태로 결정하는 “CETOP-D 입구유량인자 최적화기법”을 개발하였다. 개발된 방법을 영광 3,4호기 초기노심의 노심운전영역에 적용한 결과, 기존의 ABB/CE 방법에 비하여 정상운전영역에서 핵비등이탈에 대한 과출력여유도가 2% 가량 증가하였다.

  • SA는 천연 페놀 화합물로써 식물체가 생성하는 호르몬 중의 하나이다. SA는 특히 병저항성, 생물학적, 비생물학적 스트레스로 인해 합성이 촉진되며 식물 방어 기작을 일으킨다고 알려져 있다. 식물의 방어 기작은 바로 식물에서 얻어지는 생산량에 영향을 미치기 때문에 SA에 대한 연구가 많이 되어져 왔다. 하지만 SA를 이해하기에는 아직까지 많은 연구가 필요 되어 지고 있다. 따라서 본 연구는 애기장대에서 SA 생합성하는데 중요한 효소인 SID2가 병저항성이 강한 siz1-2 돌연변이체와 야생형에서 어떠한 조절의 차이를 보이는 지를 SID2 promoter에 의해서 조절되는 GUS와 LUC를 가진 각각의 형질전환 식물체를 통하여 관찰하였다. GUS의 발현을 GUS histochemical assay, GUS enzyme assay 그리고 LUC의 발현을 CCD 카메라를 이용한 이미지 촬영과 Luciferase enzyme assay 수행한 결과, siz1-2를 사용한 형질전환 식물체에서 야생형에 비해 발현이 높게 일어났다. 이것을 바탕으로 SA에 반응하는 유전자들의 발현이 siz1-2 돌연변이체에서는 높은 이유가 SID2의 발현이 높게 조절 받기 때문이라는 것을 SID2 promoter:GUS::LUC/siz1-2 형질전환 식물체를 통해 알 수 있었다.
