A test-bed for a shopping district has been developed urban regeneration project with empowering business people as the central figure rejecting quantitative development established by government lead and activating a distressed neighborhood through its own efforts. Additionally, the main purpose of this project is to activate commercial supremacy by making the business people voluntary participation in the project and to strengthen of ability of them. This study analyzed impact of education program for business people on empowering of business people in the case of autonomous urban regeneration project. The result of the analysis showed that the program composition did not have impact on personal/internal change, interpersonal change and socioeconomic change. However, program operation showed to have impact on personal/internal change, interpersonal change and socioeconomic change. It is expected that the findings from the study can contribute to overcome the limitations of the previous programs on empowering business people and promote participation rate of business people by empirically analyzing the impact relation of the program and opportunities to plan the program with a new objective.

Expression of cellular retinoic acid-binding protein-I (CRABP-I) in the cerebrospinal fluid of adult onset moyamoya disease and its association with clinical presentation and postoperative haemodynamic change

Jeon, Jin Sue,Ahn, Jun Hyong,Moon, Youn-joo,Cho, Won-Sang,Son, Young-Je,Kim, Seung-Ki,Wang, Kyu-Chang,Bang, Jae Seung,Kang, Hyun-Seung,Kim, Jeong Eun,Oh, Chang Wan BMJ Publishing Group Ltd 2014 Journal of neurology, neurosurgery and psychiatry Vol.85 No.7

<P><B>Objective</B></P><P>The elevation of cellular retinoic acid-binding protein-I (CRABP-I) has been suggested as a candidate in the pathogenesis of paediatric moyamoya disease (MMD). However, few studies have addressed CRABP-I in adult onset MMD. The aim of this study was to examine the expression of CRABP-I in the cerebrospinal fluid (CSF) of adult onset MMD, and to evaluate its association with clinical presentation and postoperative haemodynamic change.</P><P><B>Methods</B></P><P>This study examined the CSF from 103 patients: bilateral MMD, n=58 (56.3%); unilateral MMD, n=19 (18.4%); atherosclerotic cerebrovascular disease (ACVD), n=21 (20.4%); and control group, n=5 (4.9%). The intensity of CRABP-I was confirmed by western blotting and expressed as the median (25th–75th percentile). The differences in CRABP-I expression according to disease entity (unilateral MMD vs bilateral MMD vs ACVD), initial presenting symptoms (haemorrhage vs ischaemia) and postoperative haemodynamic change (vascular reserve in single photon emission CT and basal collateral vessels in digital subtraction angiography) were analysed.</P><P><B>Results</B></P><P>CRABP-I intensities in bilateral MMD (1.45(0.86–2.52)) were significantly higher than in unilateral MMD (0.91(0.78–1.20)) (p=0.044) or ACVD (0.85(0.66–1.11)) (p=0.004). No significant differences were noted based on the initial presenting symptoms (p=0.687). CRABP-I was not associated with improvement in vascular reserve (p=0.327), but with decrease in basal collateral vessels (p=0.023) postoperatively.</P><P><B>Conclusions</B></P><P>Higher CRABP-I in the CSF can be associated with typical bilateral MMD pathogenesis in adults. Additionally, postoperative basal collateral change may be related to the degree of CRABP-I expression.</P>

카드뮴 측적량과 붕어(Carassius auratus) 아가미 조직 변화의 상관성에 관한 연구

배희경,김은경,남성숙,문창규,전성환,나진균,박광식 한국환경독성학회 2002 환경독성보건학회지 Vol.17 No.1

Histopathological changes and cadmium accumulations in the gills were investigated in crucian carp (Carassius auratus) exposed to 0, 0.01, 0.1, 0.5 mg/l cadmium (Cd)concentrations for 25 days. After 25 days of exposure, cadmium accumulations increased in each of the different exposure concentrations. Histopathological changes in the gills of curcian carp exposed to cadmium included the acidification of mucous cell, the terminal clubbing of lamellae, the hyperplasia of epitherial cell and the curved of secondary lamellae. The similar histopathological changes were observed once the accumulations of cadmium reached the similar levels found in the present study with the different exposure schemes. Also the acidification of mucous cell in gills appeared when cadmium accumulations reached 5 ㎍/g and more. These results suggested that histopathological changes in the gills, an appearance of mucous cell acidification, be used to estimate the relation between toxic effect and cadmium accumulations in the gills.

Changes of Sugar Composition and Related Enzyme Activities during Fruit Development of Asian Pear Cultivars ‘Niitaka’ and ‘Whangkeumbae’

Jin-Ho Choi,Jang-Jeon Choi,Chang-Seok Bang,Jung-Sup Lee,Dong-Woog Choi,Hye-Sun Cho,Jun Cheul Ahn 한국원예학회 2009 Horticulture, Environment, and Biotechnology Vol.50 No.6

We report on the seasonal changes of soluble sugar accumulation and several enzyme activities related to sugar metabolism, in two Asian pear cultivars (Pyrus pyrifolia) cultivars ‘Niitaka’ and ‘Whangkeumbae’. Soluble sugar content increased as the fruit developed and its total contents in matured fruits were 104.6 and 95.1 ㎎ㆍg?¹ fresh weight for ‘Niitaka’ and ‘Whangkeumbae’, respectively. However, the fructose-glucose-sucrose-sorbitol ratio was not significantly changed. Sorbitol-6-phosphate dehydrogenase activity was maintained at high level in leaves and low in fruits throughout the fruit development, although the enzyme activity highly fluctuated in young and mature fruits. NAD-dependent sorbitol dehydrogenase activity increased sigmoidally in both leaves and fruits during fruit development, and correlated with accumulation of total sugar in fruits. Sucrose synthase and sucrose phosphate synthase (SPS) activities remained low in leaves, but higher with two peak fluctuations in fruits. The change of soluble sugar contents positively correlated with SPS activity, based on the seasonal fluctuation of SPS activity and soluble sugar accumulation.

송동호,배민진,이종호,이홍식,김선경,서호석,김찬형,전지용 大韓神經精神醫學會 1995 신경정신의학 Vol.34 No.4

Objects : Recent studies of psychosocial adjustment after hospitalization have found that the combination of maintenance antipsychotic drug treatment and psychosocial treatment including psychoeducational program are highly predictive of social rehabilitation and reduction of subsequent relapse. Two groups of patients with refractory chronic schizophrenia were preliminarily compared to determine the effect of a psychosocial treatment program on the quality of life in refractory chronic schizophrenics in an open comparative trial. Methods : One group(N=11) was assigned to approximately six months of the psychosocial treatment program(including psychoeducation program and activity program such as interpersonal relationship program, social skill training, self management program, outings, etc), in a group format, twice a week and a fixed maintenance dosage of clozapine ; while scale(QLS) was used to provide an objective measure of changes in patient's psychosocial functioning and a general assessment of psychopathology was made using the Brief Psychiatric Rating Scale(BPRS). Results : Both BPRS total positive score and the QLS total score, especially in the intrapsychic foundation factor of the scale showed a statistically significant improvement in the psychosocial treatment group. But there was no significant change in both BPRS and QLS scores over a 6-month period in the non-psychosocial treatment group. A significant negative correlation was found between the negative symptom and changes of QLS total, instrumental role and common object and activities scores respectively after receiving a 6-month of the psychosocial treatment program. Conclusion : These results suggest that a psychosocial treatment program including the integration of psychoeducation and a skill training oriented activity program serve as an outpatient treatment modality to improve the quality of the life in refractory chronic schizophrenia. To further clarify the effect of psychosocial treatment in chronic schizophrenia, a randomized trial should be done.

Structure and Property Modification of Bimodal Molecular Weight Distribution Polyethylene by Electron Beam Irradiation

Lee, Sang-Man,Jeon, Hye-Jin,Choi, Sun-Woong,Song, Hyun-Hoon,Nho, Young-Chang,Cho, Kyu-Cheol The Polymer Society of Korea 2006 Macromolecular Research Vol.14 No.6

Polyethylene of bimodal molecular weight distribution was irradiated with an electron beam. The thermal and mechanical properties were examined by DSC, small and wide angle X-ray scattering and static tensile test according to the crystal morphology of the irradiated samples. The crystal morphology change upon irradiation, as revealed by wide angle X-ray scattering, correlated well with the changes in melting enthalpy, whereas the lamellar thickness and the amorphous gap thickness remained virtually unchanged at irradiation doses up to 500 kGy. Crosslinks in the crystal domains became evident at an energy level of 250 kGy, resulting in reduced crystallinity and crystal size of the (110) and (200) planes. The samples became stiff and brittle with increased irradiation dose, which seem to be more relevant to the amount of cross links than the crystal morphology changes.

Seok‑Bon Koo,Chang‑Myeon Lee,Sang‑Jun Kwon,Jun‑Mi Jeon,Jin‑young Hur,Hong‑Kee Lee 대한금속·재료학회 2019 METALS AND MATERIALS International Vol.25 No.1

This paper experimentally confirmed that the adhesion strength of the copper layer formed on the surface of the polyimidefilm by wet plating greatly changes with the aging time. The adhesion strength of the copper layer showed a rapid increasefrom 4 to 10 h after aging had begun and then converged to a value without a significant change. The adhesion enhancementbetween polyimide film and copper layer by aging is due to the interlocking effect caused by the volume expansion of copperoxide (CuO) formed in the polyimide, the increased mobility of copper particles enlarged by the decrease of impuritiesin the copper layer grain boundaries, and the consequent change of the crystal structure of the copper layer leading to theinternal stress reduction. Such adhesion improvement can be confirmed by the progress of the cohesive failure indicatingthe breakdown of the polyimide film.

To investigate the comparative effect of spherical and aspherical RGP lens were worn during 3 weeks on rabbit's cornea. Four white rabbits were worn right eyes with spherical lens and 4 white rabbits were worn right eyes with aspherical RGP lens. Left eyes were served as control. The rabbits were sacrificed at 3 weeks after fitting and observed morphological changes by scanning electron microscopy and also investigate proliferation rate of the corneal epithelium with RGP wearing. After spherical RGP lens wearing, the epithet layer damaged compared to aspherical lens. The superficial cell layer strip off seriously, cell size significantly changed abnormal. Both spherical and aspherical RGP lens fitting group showed so many bacteria and back surface of lens was found like a fern shape. The aspherical RGP lens original material type was some formal than spherical lens. We thought that these pattern was significantly altered with spherical lens by prohibited transmitter oxygen from atmosphere therefore the epithelium shape was changed. This suggested wearing the aspherical lens might be less physiologic than shperical lens fitting. 구면과 비구면 RGP렌즈 장용시 효과를 비교하기 위하여 3주간 실험토끼 눈의 각막에 콘택트렌즈를 착용 시켜 조사하였다. 8마리의 흰 실험토끼 눈 중 4마리의 우안은 구면 RGP렌즈, 4마리의 우안은 비구면 RGP렌즈를 착용 하였다. 왼눈은 대조군으로 사용하였다. 콘택트렌즈착용 3주 후 안구를 적출하여 형태변화를 주사전자현미경으로 관찰하였으며 RGP렌즈를 착용시 각막 상피 세포증식률을 조사하였다. 구면 RGP렌즈를 착용 후, 상피층은 비구면에 비하여 손상을 받았고 상피층은 심하게 벗겨져 나갔으며 세포 크기는 비정상으로 변하였다. 구면과 비구면 렌즈 두 군 모두 많은 박테리아가 보였으며 렌즈의 후면은 양치류 모양의 형태를 발견하였다. 비구면 렌즈의 원재료는 구면렌즈보다는 다소 정형적으로 보였다. 이러한 형태는 대기로부터 산소 전달을 방해함으로 인하여 구면렌즈를 착용한 군에서 각막을 변화시킨 것으로 생각된다. 이 논문은 구면 렌즈보다는 비구면 렌즈가 생리적으로 각막 세포에 덜 영향을 미쳐 더 적합한 것을 제시한다.

Zr계 산화박막의 특성에 기여하는 비정질 형성 첨가물의 영향

전창배,이진우,김지영 국민대학교 생산기술연구소 2003 공학기술논문집 Vol.26 No.-

In this study, we investigate effects of compositional ratios on zirconium based amorphous films for alternative gate dielectric applications. To obtain amorphous films, Si, Bi as glass former materials are evaluated. The dielectric constant of Zr based films is directly related to the Zr concentration. So higher Zr concentration results in higher dielectric constant. But to obtain good thermal stability, higher glass material concentration is preferred. Amorphous thin films were deposited by reactive co-sputtering because of its easiness on compositional change. However, reactive sputtering easily causes undesirable interfacial layers. In order to reduce the interfacial layers, amorphous films is formed by oxidation. Especially, the amorphous films of Zr_(X)Bi_(1-X)O_(3.5), X = 0.5 prepared by oxidation shows CET (Capancitance Equivalent Thickness) of 17 and leakage current density of 1X10^(-2) A/㎠ at - 1.0V.
