김현(Kim, Hyun),최희선(Choi, Hee-Sun),박은별(Park, Eun-Byul) 한국도시설계학회 2014 도시설계 : 한국도시설계학회지 Vol.15 No.6

우리나라의 공원녹지정책에서는 인구당 원단위 기준을 적용한 1인당 공원면적 6㎡/인을 목표로 설정하고 있다. 게다가 2013년 수립된 국토해양부 지침에 따라 12.5㎡/인이라는 지표가 모든 기초자치단체에 일괄 적용되면서 지자체의 부담은 가중되고 있는 현실이다. 1인당 도시공원 면적의 적정성에 대한 의문과 논의는 오래전부터 지속적으로 제기되어 오고 있으나, 이러한 논의와 달리 정책적인 변화는 없다. 실제로 해외 도시의 공원 조성 면적에 대한 정확한 자료와 공원 조성 면적 관련 정책 연구는 미흡한 실정이다. 이에 본 연구에서는 문헌조사와 인터뷰조사를 실시하여 1인당 도시공원 면적 산정기준의 배경과 흐름을 파악하고 미국과 일본을 대상으로 공원 확충 정책의 흐름과 현황을 분석하였으며 그 결과는 다음과 같다. 1) 공원 조성목표의 경우 일관된 수치보다는 자치체가 자기 지역의 특성을 감안하여 목표를 수립하도록 열린 목표치를 설정한다. 2) 공원계획의 대상은 도시공원뿐만 아니라 녹지, 하천, 운동장, 도립공원, 옥상과 벽면녹화 등을 포함시켜 도시의 질적 제고를 지향하고 있다. 3) 공원정책에 있어 양적 확충보다는 공원서비스 개선, 주민 참여를 통한 질적 개선에 대하여 정책의 비중이 높아지고 있다. 이를 기반으로 본 연 구에서는 도시의 특성을 고려한 자율적인 공원면적 확충 목표 설정, 목표 대상에 녹지, 하천 등의 다양한 녹지자원 포함, 공원의 질적 서비스 향상을 위한 주민 참여와 만족도 조사가 실시되어야 함을 제안하였다. In Korea, the goal of urban park policies is obsessively set to meet 6㎡ park area/person, But since 2013, a new guideline of 12.5㎡ park area/person is established by the Ministry of Maritime Affairs and Fisheries As the new guideline is applied to all primary local authorities, the burden of local authorities is being increased. While the question related to the minimum park area per person has been consistently raised, there has been little research on the minimum. In practice, correct materials on park creation area and park area used for park-related policies in other cities around the world. Focusing on the cases in U.S. and Japan, case studies are conducted based on literature review and interviews to find out the international trends related to the minimum park area. The results are as follows. 1) In case of setting park creation goal, open target values are set such that local authorities establish goals in consideration of local characteristics instead of monolithic values. 2) The target of park project includes green belt, river, playground, provincial park, rooftop and green wall, so that quality enhancement of cities is aimed. 3) Park policies are focused on qualitative enhancement rather than quantitative expansion, through park service improvement and resident participation. Based on these suggestions, it is suggested that flexible park creation goal should be set in consideration of urban characteristics - a variety of green resources, such as greenbelt and river should be added to quantify minimum per capita park area, Resident participation and satisfaction surveys should also be performed in order to enhance qualitative measure of park service.

Background : Microvascular angina or syndrom X is heterogenous and encompasses different pathogenetic entities. Several studies suggest that microvascular angina have good prognosis and occurs predominantly in postmenopausal women. Lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and fibrinogen are the independent risk factor of acute coronary syndrome and are the chief underlying cause of atherosclerosis. We investigated clinical characteristics and markers in patients with microvascular angina. Methods : We studies 23 patients diagnosed with microvascular angina and 16 control group with negative treadmill exercise test and no significant coronary angiogram. We investigated clinical characteristics in patients group and evaluated symptom during a follow-up period of 4.2± 2.5 month. Exercise time in treadmill exercise test was compared between patients and control group. We assessed the level of markers, such as lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, CRP and ESR in two groups. Results : There is no difference in age between two groups. Patients group had a tendency to increase in female, hypertension, DM, and smoking history, but there was no statistical significance difference. Exercise duration time was significantly decreased in patients with microvascular angina (p<0,05). Serum lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholestrol, Triglyceride, ESR, Fibrinogen and Homocystein value were no significant difference between microvascular angina and control group. Only CRP was significantly high in patients with microvascular angina (p<0.05). Conclusion : There was no statistical significance difference in age, sex, hypertension, DM and smoking history between two groups but patients group had a tendency to increase the prevalence in hypertension, DM and smoking history, female. Also, Symptom improvement and disappearance in follow-up was presented in 11 patients of 19(57.9%). Exercise tolerance was worse in patients group than control group. CRP value was significantly higher in patients group than control group. There was no statistical significance difference in lipoprotein (a), total cholesterol, LDL-cholesterol, HDL-cholesterol, triglyceride, homocystein, ESR and Fibrinogen between two groups.

Background: Atopic dermatitis (AD) is a chronic disorder, with a vicious cycle of repetitive inflammation and deterioration of the epidermal barrier function. Adiponectin, an adipokine, has anti-inflammatory effects on various metabolic and inflammatory disorders. Recently, its level was found to be reduced in serum and tissue samples from AD patients. Objective: We aimed to investigate the effects of adiponectin on epidermal inflammation and barrier structures in AD skin. Methods: A three-dimensional in vitro epidermal equivalent model mimicking AD was obtained by adding an inflammatory substance cocktail to normal human epidermal equivalents (HEEs). The expression of epidermal differentiation markers, primary inflammatory mediators, and lipid biosynthetic enzymes was compared between adiponectintreated AD-HEEs, untreated control AD-HEEs, and normal HEEs. Results: Adiponectin co-treatment 1) inhibited the increase in mRNA expression of major inflammatory mediators (carbonic anhydrase II, neuron-specific NEL-like protein 2, thymic stromal lymphopoietin, interleukin-8, tumor necrosis factor-alpha, and human beta-defensin-2) from keratinocytes in AD-inflammatory HEEs, 2) enhanced the expression of lipid biosynthetic enzymes (fatty acid synthase, HMG CoA reductase, and serine-palmitoyl transferase), and 3) promoted the expression of differentiation factors, especially filaggrin. We also found that the expression of adiponectin receptor-1 and -2 decreased in the epidermis of chronic AD lesion. Conclusion: Activation of the adiponectin pathway is expected to enhance epidermal differentiation and barrier function as well as attenuate inflammatory response to AD as a therapeutic approach.

Background : The increasing incidence of multidrug-resistant gram-negative bacteria causing nosocomial infections is an important clinical problem. Isepamicin is a recently developed aminoglycoside which has been known to have potent activity against gram-negative organisms. We evaluated the in vitro activities of isepamicin and other aminoglycosides against a large number of gram-negative organisms. Materials and Methods : We tested the in vitro antimicrobial activities of isepamicin, amikacin, gentamicin, and tobramycin against 566 gram-negative organisms collected between January 2006 and June 2006 in Asan Medical Center. Minimal inhibitory concentrations (MICs) were determined and interpreted according to the recommendations of Clinical and Laboratory Standard Institute (CLSI). The breakpoint MIC used for interpretation of isepamicin was MIC≤16 ㎍/mL as susceptible, 32 ㎍/mL as intermediate, and 64 ㎍/mL as resistant. Results : The MIC_(50)/MIC_(90) of isepamicln for Escherichia coli, Klebsiella pneumon/ae, Pseudomonas aeruginosa, Acinetobacter baumannii, and Enterobacter cloacae were 1/2, 0.5/>128, 4/16, 16/>128, and 1/2 ㎍/mL, respectively. The susceptibilities for E. coli, K. pneumoniae, P. aeruginosa, A. baumannii, and E. cloacae were 100%, 86.4%, 89.7%, 50.0%, and 96.6%, respectively. For E. coli, K. pneumoniae, P. aeruginosa, and E. cloacae, isepamicln had better in vitro activities than gentamicin and tobromycin, and had similar activities with amlkacin. For A. baumanii, all four tested aminoglycosides had similar in vitro activities. Conclusion : Isepamicin had excellent in vitro activities against gram-negative organisms, except A. baumanii. The overall in vitro activities were similar with amikacin. 목적 : 그람 음성 세균은 다양한 지역사회 및 병원 획득 감염의 원인균이다. 최근에는 병원 감염을 일으키는 그람 음성 세균에서 항균제 내성균의 출현과 확산이 큰 문제가 되고 있다. Isepamicin은 최근에 소개된 gentamicin B의 유도체로 외국에서의 연구에 의하면 그람 음성 세균들에 대한 항균력이 우수함이 보고 된 바 있다. 본 연구에서는 우리나라의 임상 균주들을 대상으로 그람 음성세균에서 isepamicin의 시험관내 항균력을 기존의 아미노배당체 제재들과 비교하여 평가하고자 하였다. 재료 및 방법 : 2006년 1월에서 6월 사이에 서울아산병원 환자에서 분리된 Escherichia coli 113 균주, Klebsiella pneumoniae 110 균주, Pseudomonas aeruginosa 117 균주, Acinetobacter baumannii 108 균주, 그리고 Enterobacter cloacae 118 균주를 대상으로 isepaimcin, amikacin, gentamicin, tobramycin에 대한 최소억제농도(minimal inhibitory concentration, MIC)를 한천 희석법(Mueller-Hinton Agar)을 이용하여 측정하였다. 감수성여부는 CLSI 기준에 따랐으며, isepamicin은 MIC≤16㎍/mL를 감수성, MIC=32 ㎍/mL를 중등도 내성, MIC≥64 ㎍/mL를 내성으로 판정하였다. 결과 : Isepamicm의 E. coli, K. pneumoniae, P. aeruginosa, A baumannii, E. cloacae에 대한 MIC_(50)/MIC_(90)은 각각 1/2, 0.5/>128, 4/16, 16/>128, 1/2 ㎍/mL였고, 항균제 감수성률은 차례대로 100%, 86.4%, 89.7%, 50.0%, 96.6%였다. 기존 아미노배당체 제재들과 비교하면 E. coli, K. pneumoniae, P. aeruginosa, E. cloacae에서는 amikacin과 비슷한 감수성률을 보였고, gentamicin과 tobramycin보다 높은 감수성률을 보였다. A baumannii의 경우 isepamicin의 감수성률이 50.0%로 비교적 낮았지만 amikacin, gentamicin, tobramycin도 각각 50.0%, 46.3%, 47.2%의 감수성률을 나타내어 4가지 항균제가 모두 비슷한 항균력을 보였다. 결론 : Isepamicin은 그람 음성 세균들에 있어 기존의 아미노배당체 제재들과 비교했을 때 amikacin과는 동등한 시험관내 항균력을 보이고 gentamicin, tobramycin보다 뛰어난 시험관내 항균력을 보여 사용이 유망한 아미노배당체 중 하나라 생각된다.

백상현,박재성,차장규,홍현숙,김대호,박성진,조준희,이혜경,최진수 순천향의학연구소 2003 Journal of Soonchunhyang Medical Science Vol.9 No.2

Purpose: BOOP and NSIP also share similar clinical features such as subacute flu-like illness, the finding of bronchoalveolar lavage, the result of pulmonary function test and more favourable outcome than usual interstitial pneumonia(UIP). The author try to compare the HRCT findings of NSIP with BOOP by pattern and distribution of diseases. Materials and Methods: HRCT findings of histopathologically proven NSIP(Group Ⅰ; 6, Group Ⅱ; 7, Group Ⅲ; 2) in 15 patients(5 male, 10 female, age range, 39-69 years; mean age, 53 years), BOOP in 15 patients(6 male, 9 female, age range, 26-76 years; mean age, 52 years) were reviewed retrospectively. Results: The common pattern of the two diseases was admixed consolidation, ground glass attenuation & reticular densities with/without architectural distortion(NSIP; 53.3%, BOOP; 46.7%). The main component of the pattern wan predominantly consolidation(NSIP; 46.7%, BOOP; 73.3%) and ground glass attenuation(NSIP; 40.0%, BOOP;20.0%). Architectural distotion was more provinent finding with NSIP(mild ; 3, moderate ; 4, severe; 2) compared with BOOP(mild; 7, moderate; 2, severe; 0). The predominant overall distribution was lower lung, peribronchovascular & peripheral lung field in both of the two entities(NSIP;73.3%, BOOP; 73.3%). Peribronchovascular involvement was more common with NSIP(100%) than BOOP(80%), whereas peripheral involvement was more common with BOOP(93.3%) than NSIP(80%). Conclusion: The HRCT findings of NSIP and BOOP were similar in pattern and distribution. But NIP manifested more frequently ground-glass attenuation, whereas BOOP showed more frequently consolidation. Architectural distortion was more severe with NSIP than BOOP. NSIP invoved more frequently peribronchovascular space and BOOP were more common in peripheral lung field.

Fluctuations in Abundance and Species Composition of Fishes that appear in the set net fishery in the Dadohae Marine National Park

Cheong, Hyun-Ho,Park, Kyung-Hee national science museum of korea 2009 Journal of Korean nature Vol.2 No.1

In a joint research of the Korean Biodiversity Information Facility (KBIF), the study analyzed species composition and fluctuations in abundance of fishes caught by the set net fishery installed in the offing of Impo, Dolsando in Yeosu-si, Jeollanamdo in June and September 2008. During the study period, there were 11,180 individuals of 54 species of 39 families in 8 orders that appeared in the set net fishery in the offing of the Dadohae Marine National Park. The numbers of individuals that appeared in June and September were shown in Table 2. Among the fishes caught, the Perciformes was the dominant species with 29 species of 22 families followed by the Tetraodontiformes with 6 species of 2 families and the Pleuronectiforme with 5 species of 4 families. There appeared 3 species of 3 families of the Anguilliformes and the Beloniformes, respectively. There were 4 species of 2 families of the Clupeiformes and 3 species of 2 families of the Scorpaeniformes. There was 1 species of 1 family of the Aulopiformes. During the study period, Scomber japonicus was the dominant species with 9005 individuals followed by Trichiurus lepturus with 1500 individuals and Panpus argenteus with 184 individuals. In June, Trichiurus lepturus was dominant with 1200 individuals followed by Panpus argenteus with 150 individuals and Scomberomorus koreanus with 58 individuals. In October, Scomber japonicus was the dominant species with 9000 individuals followed by Trichiurus lepturus with 300 individuals and Scomberomorus koreanus with 45 individuals. It indicates that the dominance of a species has close relationship with water temperature because fishes migrate to feed in this season. Given the frequency of appearance, Scomber japonicus and Trichiurus lepturus most frequently appeared because they were in the middle of growing into adult fishes while the frequent appearance of Scomberomorus koreanus and Panpus argenteus, which were major species of the fishing industry, contributed to the income of fishermen. There appeared rarely seen species in the offing of Yeosu like Pelamis platurus, Rachycentron canadum (Linnaeus), Lobotes surinamensis, Kyphosus vaigiensis, Abudefduf vaigiensis and Siganus fuscescens (Houttuyn). They are subtropical fishes and seem to move here due to the warmer water affected by the global warming. Additional studies on species composition and fluctuations in abundance of fishes that appear in the set net fishery in the Dadohae Marine National Park will be continuously conducted. So, they will contribute to the increase of fishermen's income by transferring the new fish species to fishermen when newly developed rare fish species are fostered in the lab and evaluated for adaptability and growth potential. The research result will be used as basic data to secure national biological resources, and create/manage biodiversity data by building a biodiversity database network.

경연 대회를 통한 초ㆍ중고생의 창의력 신장 효과에 관한 연구

이희복,육근철,류해일,김현섭,김희수,박달원,유병환,김선효,김여상,서광수,변두원,서명석,배성효,박종석,심규철,이성희 공주대학교 과학교육연구소 2001 과학교육연구 Vol.32 No.1

미래 사회를 대비하기 위한 개인의 개성을 존중과 창의적인 능력을 지닌 인간을 양성을 목적으로 충청남도 지역의 초 ㆍ 중고등학생들을 대상으로 한 창의력 경연대회가 공주대학교 과학교육연구소에서 개최되었다. 충청남도 초 ㆍ중 ㆍ 고등학생들을 대상으로 실시한 창의력 경연대회는 창조적 아이디어를 내어 스스로 문제를 해결해 나갈 수 있는 교육 프로그램을 제공하는 좋은 기회였음이 확인되었으나, 일부의 팀에서만 참신하고 재미있는 아이디어들이 제안되었다. 여학생의 참가자 수가 상당히 증가하였으며, 대체적으로 입상권의 학생들의 상당 부분이 여학생이라는 것이 특이할만하다. 학년이 올라감에 따라서 창의적인 아이디어를 내는 양이나 질에 있어서 뒤떨어지는 것으로 분석되었으며, 토론 학습의 적응력이 미흡하고 발표력 및 청취력에 있어서도 떨어지는 것으로 나타났다. 따라서 중 ㆍ고등학교의 학교교육에서도 학생들에게 프로젝트형 탐구학습 프로그램의 적용은 물론 토론식 수습을 통한 학생들의 사고의 전환의 기회를 제공해야 할 것으로 사료된다. The creativity competition was held to foster the creativity of elementary and secondary school students in the Institute of Science Education, Kongju national University. It was found that the creativity competition effected on the improvement of inventing creative ideas and problem solving activities. But, only some competitors participated in semifinal and final contests, presented original and interesting ideas. More female students participated in competition than last year. More female participants were awarded a prize than males. Totally, participants were defective in discussion and communication, and presentation and listening ideas. Increasing grades correlated inversely with creativity and originality. There is need of inquiry project teaming programs and presenting opportunities of conversion of thinking by discussing instructions in school

조혈모세포이식 환자에서 침습성 진균 감염에 대한 Micafungin의 예방 효과 및 안전성

김시현,이동건,최수미,권재철,박선희,최정현,유진홍,이성은,조병식,김유진,이석,김희제,민창기,조석구,김동욱,이종욱,민우성,박종원 대한감염학회 2010 감염과 화학요법 Vol.42 No.3

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.
