Intussusception and acute appendicitis are common emergency conditions in children. They should be promptly differentiated in pediatric patients presenting with suggestive symptoms. However, both diseases may occur simultaneously. Herein, we present two cases of intussusception of the appendix accompanied with appendicitis.

유행과 낭만의 거리 강남 가로수길. 이곳에 가면 국내 유명 브랜드 패션매장들이 즐비하다. 그중 동양그룹 Mag Mag 매장 1층 입구에 깜짝 놀랄만한 자판기 하나가 설치되어 있다. 패션 양말을 파는 자판기이다. 블랙 톤의 세련된 자판기 디자인에 판매상품 디스플레이도 획기적이다. 패션양말들이 빨래 줄에 걸린 디스플레이를 보는 순간 '기발하다'는 생각이 절로 든다. '자판기로 양말을 팔아가지고 수익이 될까?' 놀랍게도 이런 의구심을 한방에 날렸다. 이 재미있고 독특한 자판기 앞으로 사람들이 몰려들고 있는 것. 운영 3주 만에 아이디어 자판기로서 성공시대를 예감케 한다. 이 자판기를 과연 누가 운영할까? 놀랍게도 27살의 여성이다. 아이해이트몬데이(i hate Monday)사(社)의 홍정미 사장. 얼마전까지 자판기의 '자'짜도몰랐다 한다. 이런 그녀가 양말자판기를 런칭해 많은 화제와 인기를 모으고 있다.

In general, the transformation of coordinates in GPS is carried out by 3 dimensional transformation method with 3-10 parameter. In korea, the coordinates of transformation points ware determined are adjusted in-dependently by planimetry and the height, and also the weight of observations were not properly applied to the adjustment. In this study, two different transformation methods are tested and analysed by the field test, and it is finally found that 2 dimensional method is more efficient way than 3 dimensional classical transformation method.

The Theo Jansen mechanism using 1 degree of freedom is special system of walking robot. The trajectory made by the point of ground position is similar to other walking robot using many degrees of freedom. Because of diversity of design parameter of the Jansen mechanism, it makes a lot of trajectory and takes possibilities of optimization. However this research doesn't focus on the optimization of trajectory, but it focused on comprehensive design of the robot using well-known trajectory and line tracer logic to go fast and accurate along the line. The logic to follow a line has many kinds of possibility of algorithm. To eliminate uncertainty about recognizing a line, I divide the case of line following situation and make optimized logic.

Various digital topographic maps including 1:1,000 and 1:5,000 have been produced for years and these digital maps are expected to serve a wide range of purposes. Most previous research about measuring positional accuracy for digital topographic maps depends int a method that acquires sample points from the tested map and compares to the corresponding known true locations using some statistics. Recently, a simple method for measuring positional accuracy for linear features is introduced but it has substantial problems applying to the spatial features such as roads, railroads, streams represented with double lines on the recently produced 1:1,000 and 1:5,000 digital topographic maps. This study develops and implements an effective method that measures road objects represented in the 1:5,000 digital topographic maps using a conventional GIS software. We also apply this method to a small study area located in Kangnam Gu, Seoul and illustrate the usefulness of this method.

To successfully create a low-carbon landscape in order to become a low-carbon city, it is necessary to understand the dynamics of artificial greening's resources on a multi-scale. Additionally, the effects of carbon storage should be quantitatively evaluated. The purpose of this study is to simulate and evaluate the changes in carbon storages of artificial ground trees using system dynamics throughout a long-term period. The process consisted of analyzing the dynamics of the multi-scale carbon cycle by using a casual loop diagram as well as simulating carbon storage changes in the green roof of the Gangnam-gu office building in 2008, 2018, 2028, and 2038. Results of the study are as follows. First, the causal loop diagram representing the relationship between the carbon storage of the artificial ground trees and the urban carbon cycle demonstrates that the carbon storage of the trees possess mutual cross-scale dynamics. Second, the main variables for the simulation model collected 'Biomass,' 'Carbon storage,' 'Dead organic matter,' and 'Carbon absorption,'and validated a high coefficient of determination, the value being ($R^2$=0.725, p<0.05). Third, as a result of the simulation model, we found that the variation in ranking of tree species was changing over time. This study also suggested the specific species of tree-such as Acer palmatum var. amoenum, Pinus densiflora, and Betula platyphylla-are used to improve the carbon storage in the green roof of the Gangnam-gu office building. This study can help contribute to developing quantitative and scientific criteria when designing, managing, and developing programs on low-carbon landscapes.

Traffic information protocol in DMB is very different from existing analog broadcasting and wireless communication network. In this paper, we examined whether traffic information protocol of Europe Broadcasting Union(TPEG) is applicable to domestic DMB. Also, we proposed a division of classification on kinds of franc information, and related data that it is required to transmit traffic information of TPEG form. We composed of experiment equipment and studied whether is expressed traffic informations as like accident, event, traffic condition and CCTV image on car navigation system. The results obtained it can be given expression to phrases from TPEG streaming data and to link with electronics map by decoding TPEG straming data. Also it can be expressed CCTV and graphic image which is composed of TPEG form.

This study has examined layout of communal outdoor space and welfare facilities in the nation's very first senior apartment complex in Segok-dong, Gangnam-gu that has been developed by Seoul City. In order for this space to play a role as a center of communication: 1) A center space of community should be created at the point of intersection of main moving lines of pedestrians. 2) Hierarchical area should be set up between main moving lines of walking and communal outdoor space. 3) It should be designed in a way to reflect demands of seniors and be accommodated their activities and behaviors. 4) It should be functionally connected to local infrastructure facilities so that it can promote social exchanges among seniors. Points to be considered in welfare facilities: 1) They should be placed at the center of the complex to provide convenience to all seniors. 2) Area of senior citizen center should be subject to flexible legal regulation in light of the unique characteristics of the Complex. 3) in case that welfare facilities are installed in the same space, intermediate space is required to alleviate collision between private space and public space. 4) Senior assistance facilities should put more emphasis on running programs that make good use of the space than on securing the space itself.
