도시광장은 시민들의 일상생활에 밀접한 영향을 줄 수 있는 도시의 대표적인 공공 오픈 스페이스 중의 하나이다. 대부분의 도시광장은 도시의 중심부에 위치하고 있으며, 도시민의 커뮤니티를 형성하고 여가 문화 활동, 오픈 마켓, 정치적 집회 등과 같은 다양한 활동을 할 수 있는 공간으로 이용된다. 최근 우리나라에 공공 오픈 스페이스로 조성된 도시광장은 도시민들의 요구에 의한 중심 대 광장 유형의 광장으로 볼 수 있으며, 여러 가지 특징을 갖고 다양한 기능을 수행할 수 있는 공간으로 조성되었다. 본 연구에서는 서울 시내에 중심 대 광장의 유형으로 보여지는 광화문 광장, 서울 광장, 청계 광장을 연구 대상지로 선정하고, 광장의 구성요소 및 특성에 대한 만족도를 측정하여 분석하고, 공간 이용 만족도를 조사하여 구성요소 및 특성에 대한 만족도와의 관계성을 파악하고자 한다. 각각의 광장에서 수집한 설문조사 결과는 빈도분석, 요인분석, 일원배 치분산분석, 상관관계분석, 회귀분석 등을 이용하여 분석하였다. 연구 결과를 요약하면, 첫째, 도시광장 구성요소 및 특성에 대한 만족도를 요인분석한 결과, 구성요소, 이용성, 쾌적성/안전성, 공간특성 요인으로 구분되었다. 이용성 요인에 대한 만족도가 다른 요인에 비해 높은 것으로 나타나, 연구 대상지가 오픈 스페이스의 역할을 수행하고 있음을 확인할 수 있었다. 둘째, 광장의 이용 만족도는 전반적으로 높으며, 특히, 다양한 구성요소가 조성되어 있는 광화문 광장의 만족도가 높은 것으로 나타났다. 마지막으로, 도시광장의 공간 이용에 대한 만족도는 이용성 요인에 대한 만족도에 가장 큰 영향을 받으며, 나머지 요인들과도 통계적으로 유의한 관계있다는 것을 알 수 있었다. 본 연구의 결과는 도시광장의 계획 및 이용에 관한 만족사항을 반영하여, 도시 오픈 스페이스의 역할을 하는 도시광장의 발전방향을 제시하는 데 일조할 것이라 기대된다. City squares are public open spaces which are closely related to the peoples daily lives. Most squares are located in the center of the city, and they are usually used for community gatherings and they are suitable for open markets, music concerts, political rallies, and other events. City squares also play an important role as a grand public place operating in multi functions that require involvement of more people. The purpose of this study is to examine satisfaction on the spatial components, characteristics, and the user satisfaction in City Squares. The slady also analyzed the relationship between the satisfaction about spatial components, characteristics and it also shows that the user satisfaction is followed. This study sites are made in 3 grand public places in the center of Seoul including the Seoul plaza, Cheonggye Plaza, and Gwanghwarnun Square. Data were analyzed using several statistical methods such as descriptive statistics, factor analysis, ANOVA, correlation and regression. Results of the study are as follows: First, factor analysis carried out to extract the various factors of satisfaction on the sites; spatial components, usability, amenity/security, and spatial characteristics. User satisfaction concerning usability factor was higher than the satisfaction of the other factors. This result represented that the slady sites play an important role to the public open spaces in the city. Second, users showed high user satisfaction to study sites, and user satisfaction rate toward the Gwanghwarnun Square is the highest because of its facility planuing. Finally, user satisfactim was strongly correlated on the usability factor of spatial planning. Also, the significant correlations between the user satisfaction and the other factors such as spatial components, security, and spatial characteristics of spatial planning are presented. Results of this study can help guide the planning and management of the city square as a public open space based on the understanding of user perception and satisfaction.

요로 감염증 환아에서 배뇨성 요로조영술을 시행하는 적절한 시기에 대한 평가

이정아,최제은,김성미,정진화,Lee Jung A,Choi Jae Eun,Kim Sung Mi,Jung Jin Hwa 대한소아신장학회 2001 Childhood kidney diseases Vol.5 No.2

목 적 : 요의 감염증 환아에서 방광 요관 역류는 흔히 발견되는 이상으로 대부분의 연구에서 요로 감염 3-6주 후 VCUG를 시행하는 것을 권유하고 있다. 하지만 검사를 하기 위해 기다리는 동안 만성 신질환으로 진행할 가능성이 있으며 추적 관찰에 실패하여 검사자체를 하지 못 하는 환아가 발생 할 수 있다. 따라서, 본 연구에서는 요로 감염 후 VCUG를 시행하는 시기가 요관 방광 역류의 빈도와 정도에 영향을 미치는지를 조사하였다. 대상 및 방법 : 1997년 3월부터 2000년 12월까지 요로 감염으로 메리놀병원 소아과에 내원한 환아 213명을 대상으로 후향적으로 조사하였다. 이들 환아를 요로 감염 진단 후 1주일 이내에 VCUG를 시행한 군(A군, 142명)과 1주일 이후에 VCUG를 시행한 군(B군, 71명)으로 나누어 각각을 비교하였다. 결 과 : A군의 $19\%$(27/142명), B군의 $18\%$(6/71명)에서 역류가 발견되었으며 통계학적으로 의미 있는 차이가 없었다(P=0.854). 하지만, 실제로 계획된 VCUG를 받은 환아는 A군 $100\%$, B군 $48\%$로 의미있은 차이가 있었으며(P<0.001), B군 환아에서 감염 후 VCUG를 받은 기간과 역류 정도에는 의미 있는 차이가 없었다(P=0.001). 결 론 : 본 연구의 결과에 따르면 요로 감염후 VCUG를 하는 기간과 역류의 빈도와 정도에는 차이가 없으므로 환아가 입원하고 있는 동안 VCUG를 시행하는 건이 더욱 바람직하며 이에 대한 보다 많은 연구가 필요하다고 생각한다. Purpose : Urinary tract infection is a common problem in children. To evaluate for reflux most authorities recommend a voiding cystourethrogram 3 to 6 weeks after the first urinary tract infection. But during the 3 to 6 weeks interval, patients may fail to show up for the scheduled VCUG and thus risk for loss of follow up. We analyzed patient's records to evaluate whether the timing of VCUG after UTI influenced the prevalence or severity of VUR. Methods : We retrospectively reviewed 213 children diagnosed with UTI from March 1997 to December 2000. These children were divided into 2 groups according to whether they had VCUG scheduled to be performed either within 1 weeks after the diagnosis of UTI (Group A) or later than 1 week after the diagnosis(Group B). We compared tile presence and severity of reflux in the 2 groups. Results : Reflux was present in $19\%$ of the patients studied within 1 week after UTI and in $18\%$ of those studied after 1 week. This difference was not statistically significant. Whereas $100\%$ of the scheduled VCUGs in the Group A were performed, only $48\%$ of those scheduled in the Group B were performed. This difference is statistically significant. Conclusion : Because there was no significant difference between the presence or severity of reflux and timing of VCUG after UTI, we suggest that a hospitalized patient with UTI should have VCUG performed before discharge.

MgO 및 TiO₂가 첨가된 알루미나의 치밀화와 입성장 거동

이정아,김정주,Lee, Jung-A,Kim, Jeong-Joo 한국세라믹학회 2002 한국세라믹학회지 Vol.39 No.11

Densification and grain growth behavior of MgO and .$TiO_2$-doped alumina ceramics were investigated. MgO was found to inhibit grain growth and to promote densification, but .$TiO_2$ acted to promote grain growth more than densification. The density which showed the maximum shrinkage rate was investigated in the plot of shrinkage rate versus density. The data suggests that the maximum shrinkage rate separates the two kinetic regimes, below the density of maximum shrinkage, the regime associated with densification and above the maxima, the regime associated with the grain growth. The plot exhibits a maximum which shifts to higher temperatures with MgO doping and to lower with .$TiO_2$ doping. 알루미나 세라믹스에 MgO와 $TiO_2$를 각각 단독으로 첨가했을 때의 치밀화와 소결 거동을 수축률-소결 밀도 관계를 통해 비교 조사하였다. MgO가 첨가되었을 때는 소결 전과정을 통해 입성장은 억제되고 치밀화는 촉진되었으나, $TiO_2$가 첨가되었을 때는 입성장은 촉진된 반면 치밀화는 떨어졌다. 또한 입자 크기, 밀도, 수축률등을 통해 수축률-소결 밀도 관계를 구하여 최대 수축률을 나타내는 밀도값(Density of Maximum Shrinkage Rate:${\rho}$J.S.R)을 조사해 보았다. 이때 최대 수축률을 나타내는 밀도값보다 낮은 밀도를 보이는 영역에서는 치밀화가 입성장보다 우세하게 진행되었으며 최대 수축률을 나타내는 밀도값보다 높은 밀도의 영역에서는 입성장이 보다 우세하게 진행되는 것으로 추정하였다. 이때 최대 수축률을 나타내는 밀도값은 $TiO_2$가 첨가된 알루미나 < 순수 알루미나 < MgO가 첨가된 알루미나의 순서로 높은 값을 보였다.

The purpose of this study was to produce the regression equation from non-exercise $VO_{2max}$ of healthy young adults and to develop a maximal oxygen consumption ($VO_{2max}$) regression model. This model was based on heart rate non-exercise predictor variables (rest heart rate, maximal heart rate/rest heart rate), as an extra addition to the general regression which can reflect an individual's inherent or acquired cardiorespiratory fitness. The subjects were 101 healthy young adults aged 19 to 35 years. Exercise testing was measured by using a Balke protocol for treadmill and indirect calorimetry. The prediction equation was analyzed by using stepwise multiple regression procedures. The mean of $VO_{2max}$ was $39.02{\pm}6.72\;m{\ell}/kg/min$ (mean${\pm}$SD). The greatest variable correlated to $VO_{2max}$ was %fat. The predictor variable used in the non-exercise $VO_{2max}$ included %fat, gender, habitual physical activity and $HR_{max}/HR_{rest}$. The non-exercise $VO_{2max}$ estimation was as follows: $VO_{2max}$($m{\ell}/kg/min$)=55.58-.41(%fat)+.59(physical activity rating)-2.69($HR_{max}/HR_{rest}$)-5.36 (male=0, female=1); (R=.85, SEE=3.64, R2=.72: including heart rate variable); $VO_{2max}$($m{\ell}/kg/min$)=48.47-.41(%fat)+.45(physical activity rating)-5.12 (male=0, female=1); (R=.84, SEE=3.74, R2=.70: with the exception of heart rate variable). As an added heart rate variable, there was only a 2% coefficient of determination improved. Therefore, these results demonstrated that heart rate variable correlation with a non-exercise regression model was very low. In conclusion, for healthy young korean adults, those variables that can affect non-exercise $VO_{2max}$ estimation turned out to be only % fat, gender, and physical activity. We suggest that further research of predictor variables for non-exercise $VO_{2max}$ is necessary for different patient groups who cannot perform maximal exercise or submaximal exercise.

친환경 아파트 거주자의 옥외환경에 관한 인식분석

이정아,전진형,Lee, Jung-A,Chon, Jin-Hyung 한국조경학회 2008 韓國造景學會誌 Vol.35 No.6

The purpose of this study is to examine residents' perceptions of the outdoor spaces of environmentally-friendly apartment complexes focused on quality of life. On-site intercept surveys were performed to collect data and samples were selected from the residents who are currently living in two different environmentally-friendly certified apartment complexes. This study has examined importance and satisfaction of outdoor spaces of the study sites as they relate to quality of life, as well as they correlation between the New Environmental Paradigm(NEP), and satisfaction and loyalty, respectively. Data were analyzed using several statistical methods including descriptive statistics, Importance-Satisfaction Analysis(ISA), t-test, and correlation. The results suggest that outdoor spaces of the apartment complexes are perceived as an important place to improve residents' quality of life. Residents showed a high satisfaction rate to the natural environmental features(e.g. natural areas present, amenity of space) while they showed a lower satisfaction rate to the social environmental features(e.g. access to public transportation). Although most residents tend to have the New Environmental Paradigm based on the study results, NEP did not influence the level of satisfaction in environmentally-friendly apartment complexes. In contrast, there was a significant relationship between NEP and loyalty. In addition, a strong correlation emerged between satisfaction of outdoor spaces and loyalty to the housing estates. Given these results, various recommendations were given to promote better use of outdoor spaces of dwellings to improve residents' quality of life.
