  • Tris (2-methyl-1-aziridinyl) phosphine oxide (MAPO) is extremely poisonous and persistent in aqueous media. An efficient UV/nano$TiO_2$ process was employed for its mineralization in a high duty falling film photo-reactor based on an experimental design scheme that considers interactions between the main variables. The influencing variables and their range were determined with preliminary studies. The results show substrate mineralization to some extent under mild conditions of: T = $30^{\circ}C$, pH = 8.5, $[MAPO]_0=60\;mg\;L^{-1}$ and $[TiO_2]=110\;mg\;L^{-1}$. The relative importance of the influencing parameters were initial pH > temperature > $[MAPO]_0$ > [$TiO_2$]; while the interdependence of all the parameters was significant. Accordingly, a reduced quadratic expression was developed. Meanwhile, mineralization kinetic studies, based on chemical oxygen demand, revealed a power law model with order of 2.6 during process time until 150 min.

  • The traditional Korean heating system ondol, one of the most important characteristics of Korean architecture, still remains as hydronic floor heating. Various studies have been conducted on the modernization of ondol, but the process of introducing the hydronic floor heating has not been seriously studied so far. Therefore, this paper aims to demonstrate how the hydronic floor heating had been introduced to Korea, taking the 1950s and 1960s Haengchon, Jongam, and Mapo Apartments for example - these three are regarded as the first Korean apartment houses after the Korean War. While Western advanced construction technology was imported for these apartments, various methods of modernizing ondol were also considered. What was remarkable in these attempts is that hydronic floor heating first appeared in Mapo 1st Apartment in 1962, because this is the universal heating method in the present Korea. This fact signifies that the traditional principle of floor heating has been maintained, and it would also be meaningful in terms of architectural exchanges between East and West, if considered along with Wright's application of the Korean heating principle to his houses since 1930s.

  • This study is to examine the public participation activities in the progress of the design competition, purposed to provide urban public spaces by the reuse of industrial heritages. Through the case studies of Berlin Tempelhof Parkland, Mapo Depot and Seoul Station 7017, following activities are common: citizen idea competition, forum, field trip, survey and winners exhibition. However, those activities are more closely organized to the competition process in Tempelhof Parkland, than other tow projects of Seoul Metropolitan Government. Also, it enables to clear and develop the public ideas more that those programs such as survey, citizen idea competition and field trip, are linked to each other in the case of Tempelhof Parkland. It could be achieved by the unified organization between competition preparation and public participation operation.

  • New Seoul Town is a new town in Seoul Mapo-Gu, Which is planed by Seoul metropolitan government. There are Nanji Waste reclaimed land and Seoul world-cup stadium, which is under construction in the new town. This study is executed for urban nature conservation by assessing the biotope in the new town. The biotope map is mae by the selective mapping method, and assessing the biotope is executed by a quick method, which is originated with R. Wittig and Scheriber(1983). The assessment criteria include the period of development, area, rarity and variety of habitat condition. In the result from this study, biotope type of the new town is classified eight types, and all biotope type is valuable for nature conservation. The reason of this result is because of little natural area which is rice field, farm field, forest, swampy land, etc, except New Seoul Town, in Seoul Mapo-Gu. And so, Biotope in New A Seoul Town, must be conserved and restored in new town urban planning.

  • The purpose of this research was two-folds; first, to investigate the type of soil contaminated in the Hunsang excavated from the Milchang-gun burial of Mapo for the purpose of proposing the adequate washing method, second, to utilize the chemical degradation result obtained from the previous research to identify the natural dye source used in the Hunsang textile. The application of KS K0251 test showed that the soil was more oleophilic than hydrophilic thus indicating that wet cleaning was more adequate that dry cleaning for the removal of Hunsang soil. The GC-MS result of the Hunsang extraction showed dimethyl phthalate and 2,4-di-tert-butylphenol as its degradation product and these coincided with the degradation products from the alizarin standard data of previous research. The comparison of the two suggested that it is likely that Hunsang was dyed with madder which has alizarin as its major chromophore.

  • This study aims to understand characteristics and roles of community media in Seoul to discuss the meanings of the media. Community media is constructed based upon the networks of relations of community participants, whose characteristic relations of participants within the network determines the roles and meanings of the media for the community. Research have shown that community media's unique open, participatory, and horizontal communicative structures enable to realize such objects. For this study, we chose Mapo FM to conduct case study based upon network analysis of 'participant network' of the media. In particular, we tried to measure the density and centrality of the network, which can explain the relational characteristics of the networks of the media. In addition, we also conducted in-depth interviews of participants to better understand the problems and meanings of the community media. The findings suggest that unlike the conceptual and theoretical assumptions, the community media under the study lacks of open, participatory, and horizontal ways of participation in the media.

  • Purpose : Shigellosis is still an important cause of acute food-borne diarrheal diseases throughout the world. We investigated the transmission routes and clinical course through the outbreak of shigellosis in Mapo-Gu, Seoul. Methods : From October 7th to November 19th in 2005, Mapo-Gu public health center had referred 32 patients with confirmed or suspected shigellosis to the National Medical Center. We had investigated source of infection, epidemiology, laboratory findings, and clinical course of the cases occurred during this outbreak. Results : Among 32 patients, 24 patients had been confirmed with shigellosis, 8 patients had been diagnosed with suspected shigellosis. They ranged in age from 5 months to 12 years old and their mean age was 6.5 years. The clinical manifestations were as follows; diarrhea, fever, abdominal pain and asymptomatic condition. Symptoms had sustained for 3.7 days on the average. S. sonnei were cultured by rectal swab and founded to be resistant to ampicillin and TMP/SMX except to 3rd generation cephalosporin. After treatment with antibiotics such as cefixime and ceftriaxone or imipenem and conservative treatment with electrolyte and fluid replacement for 5~7 days, Stool cultures of the rectal swab grew no Shigella in these cases except 3 cases. Conclusion : An outbreak of shigellosis had occurred in a preschool and elementary school children. From the same results of antimicrobial susceptibility and pulsed-field gel electrophoresis patterns in this study, we suggest that the outbreak of shigellosis in this report had been originated from a single strain. According to all negative results about suspected food and water cultures, we couldn't find out source of infection. Through materials offerred by Mapo-Gu Public Health Center, we presumed the trasmission routes probably were person-to-person.

  • This design proposal was accepted to a design competition for the improvement of Indi Youth Street, Mapo-Gu, which was held by the Seoul Metropolitan Government in June, 2000. The \`Hong-ik University District\` projected area consists of several streets, where the independent and youth culture unique to this area is blossoming-Indi music, underground arts, and historic meaning of the area as an estuary of Mapo. The site is also expected to attract many citizens and fereigners because of convenient accessibility of the new subway station to the Inchon International Airport and because of many attractions on the street- foods, music, art and people. Accordingly, the proposal set the main design concept of this project as \`the Street of Youth Culture\` considering its special and social status as well as the physical improvement of the street environment. With this concept in mind, the proposal designed the improvement of the physical conditions based on the motive of \`the Street of Youth Culture\`, having Indi/under art, Indi/ under music, Indi/under drama and Indi/multimedia animation. This design proposal of the Street of Youth Culture consist of three segments, which symbolize the millenium Youth Plaza, MultiMedia Animation Pocket and Arts Exhibition Pocket based on unity and balance. This plan has the ultimate aim of making the district one of the people\`s favorite streets in Seoul, which people love to visit again and find the vivacity of the new millennium youth culture.

  • The goal of this study is to identify the sense of community that is present in people based on different housing types and to devise methods for a sustainable community by comparing and contrasting the factors affecting the sense of community between apartment residents and non-apartment residents. The data for the analysis was collected using the questionnaire survey method from July 23~30, 2015, and the sample consisted of 225 respondents living in Gongdukdong, Mapo-gu, in Seoul. The results were as follows: (1) The attitude and sense of community in both groups turned out to be near the middle range without showing a significant difference. (2) All the variables related to the attitude towards the community that have impacts on the development of sense of community show significant positive correlations in both groups. (3) Determining factors of the sense of community are -in the order of importance- frequency of interaction, community awareness, and satisfaction level of community facilities. This result indicates that developing customized programs to enhance community interactions and making people aware of policies and support available are more effective in building a strong sense of community than expanding and refurbishing community facilities.
