Much has been made of the changes over time to apartment complexes during the era of rapid development in Korea. This study aimed at analyzing the chronological changes since the 1970s in the laws and regulations governing outdoor space and the residents' appreciation of outdoor space in Daejeon's apartment complexes. The results of this study can be summarized as follows: 1. Similar changes can be found throughout Daejeon's apartment complexes. As time has passed, the building-to-land ratio and the floor-to-land ratio have deceased. The high density trend of apartment complexes has continued until very recently. 2. Although residents' satisfaction with outdoor space around apartments has improved, land for athletic and commercial spaces still remains at its lowest level. Therefore, these kinds of spaces need improvement. 3. Comparing the characteristics of outdoor space in apartment complexes from the 1980s to present indicates that current apartment residents are much more satisfied with the outdoor space, but are conscious of the lack of adequate facilities for the elderly and the handicapped people, and of the hiか density of their apartment complexes. Therefore, these essential consciousness should also be further improved. 4. The residents are gradually becoming aware of changes to the outdoor space that have occurred over time in the apartment complexes, such as in the areas allowed to parking, pedestrians, and athletics. 5. These chronological changes relate to the residents' interest in the changes that have occurred to the outdoor space, especially the convenience of parking, the color of the buildings, the form of the buildings, and the shape of the roofs.

Eighteen catholic churches, built in the Chungbuk area(Cheongju diocese) under the jurisdiction of the American Maryknoll missioners in 1953-1969, are not constrained by specific architectural styles, unlike those built by other foreign Catholic missionary organizations. The same is true of Naedeok-dong cathedral in Cheongju, which is the highest hierarchy and representative church of the diocese. Nevertheless, it has unique architectural features that distinguish it from other churches in the diocese. This study examined what those features were, how they were embodied, and their origins. This study also shows that the features are common in the missioners' churches in Pyeogyang diocese in 1923-1942 and that Father James V. Pardy and the architect Tae-Bong Park, played a bridging role in having the same features between the Pyeogyang and Cheongju diocese. In conclusion, this study summarizes the significance of Naedeok-dong cathedral in relation to the missioners' ideology, in the history of the churches in 1923-1969 and Korean modern Catholic church architecture. To this end, a literature search that utilized mainly primary sources, such as newly discovered architectural drawings, photographs, and text related to the cathedral, was performed.

In this study, new methodology to estimate the reliability of a water distribution system using HSPDA model is suggested. In general, the reliability of a water distribution system can be determined by estimating either the ratio of the required demand to the available demand or the ratio of the number of nodes with sufficient pressure head to the number of nodes with insufficient pressure head when the abnormal operating condition occurs. To perform this approach, hydraulic analysis under the abnormal operating condition is essential. However, if the Demand-Driven Analysis (DDA) which is dependant on the assumption that the required demand at a demand node is always satisfied regardless of actual nodal pressure head is used to estimate the reliability of a water distribution system, the reliability may be underestimated due to the defect of the DDA. Therefore, it is necessary to apply the Pressure-Driven Analysis (PDA) having a different assumption to the DDA's which is that available nodal demand is proportion to nodal pressure head. However, because previous study used a semi-PDA model and the PDA model which had limited applicability depending on the characteristics of a network, proper estimation of the reliability of a water distribution system was impossible. Thus, in this study, a new methodology is suggested by using HSPDA model which can overcome weak points of existing PDA model and Available Demand Fraction (ADF) index to estimate the reliability. The HSPDA can simulate the hydraulic condition of a water distribution system under abnormal operating condition and based on the hydraulic condition simulated, ADF index at each node is calculated to quantify the reliability of a water distribution system. The suggested model is applied to sample networks and the results are compared with those of existing method to demonstrate its applicability.

The Daetongsa temple is the earliest temple to be constructed during the era of the Three Kingdoms in ancient Korea. The main architect, purpose, and name of the temple have been confirmed through ancient literature and archeological materials carved in the Chinese letter, Daetong, excavated around Gongju. However, the location and range of the temple have remained elusive and were discussed in various studies. In this study, we examine the roof tiles obtained from the presumed site of the Daetongsa temple. The tiles were found to contain traces of red paint (red pigments) on their surface and analyzed using nondestructive techniques. The results imply that roof tiles were made using clay tablets and wooden cylinders, with latticed cloth in between. Additionally, some wooden cylinders appeared to comprise numerous wooden plates tied together by strings. The clay tablets used to make the roof tiles were produced from the source clay via the sorting process. The traces of red paint on the surface of the roof tiles were verified to be traditional pigments used for painting wooden buildings. These pigments were extracted from red ocher or red clay (Seokganju), mainly consisting of iron oxide. In the literature, the location of provenance sites for Seokganju is estimated to be far from Gongju. However, the materials for extracting the red pigments were relatively easy to source because most rocks comprised iron oxides. Therefore, it is necessary to discuss the provenance of the red pigments around the presumed site of Daetongsa.

This study classified wintertime bioclimatic zones of South Korea based on daytime and nighttime distribution of wind chill index calculated from climate data during the coldest month for latest 30 years (1971- 2000). The results show that the winter daytime and nighttime wind chill index were influenced by climatic factors such as elevation, land-sea breeze, topology, and sea currents etc. as well as climatic components such as temperature, wind speed, and sunshine, so that South Korea was divided into five bioclimatic zones; Cool day- cold night zone, Keen day- Cold night zone, Keen day-Very Cold night zone, Cold day and night zone, and Cold day-Extremely Cold night zone. Especially, coasts and island areas, except for south coast of Korea, shows Keen bioclimatic response during daytime and Very Cold bioclimatic response during nighttime. This indicates that coasts and island areas, except for south coast of Korea are affected by moonson and land-sea breeze. In addition, highly elevated Daegwallyeong shows Cold bioclimatic response during daytime and Extremely Cold during nighttime due to the influence of adiabatic temperature lapse rate and monsoon. This study offers basic data necessary to make decisions concerning insulation such as clothing and architect etc. by classifying winter bioclimatic zones of South Korea based on various daytime and nighttime distribution of wind chill.

In this study, satellite data (MTSAT-1R), a numerical weather prediction model, RDAPS (Regional Data Assimilation and Prediction System) output, ground weather station data, and artificial neural networks were used to improve the accuracy of summer rainfall forecasts. The developed model was applied to the Seoul station to forecast the rainfall at 3, 6, 9, and 12-hour lead times. Also to reflect the different weather conditions during the summer season which is related to the frontal precipitation and the cyclonic precipitation such as Jangma and Typhoon, the neural network models were formed for two different periods of June-July and August-September respectively. The rainfall forecast model was trained during the summer season of 2006 and 2008 and was verified for that of 2009 based on the data availability. The results demonstrated that the model allows us to get the improved rainfall forecasts until lead time of 6 hour, but there is still a large room to improve the rainfall forecast skill.

The proximities of Cheonggye creek was a maj or space for the gathering of large populations from the past times and it is also a place containing the joy, anger, sorrow, pleasure and lives of the citizens. The Cheonggye creek which flowed downtown of Seoul throughout many historical events had disappeared into history completely in the modernization process due to the contamination with life sewages and overflow. However, the city authority of Seoul decided to restore it to its shape before covering the creek by means of dismantling the old elevated ways in Cheonggye creek in line with the Large Scale City Movement Project to revive the grey city and to improve the quality of the city landscape in 2002. The cultural space was created by activating the old town sphere in Cheonggye Creek and the amenities of the giant city was improved by the cultural and natural wave created along the creek. In addition, the educational opportunity has been provided to the citizens by means of reviving its historical nature. The design and cultural value of the Cheonggye Plaza were restored for the mean time and the urban environment requested during modem times was established. The Cheonggye Plaza which heightened the balanced development in Seoul which has been developed in an unbalanced way by dividing into northern and southern area of the river is very meaningful in the viewpoint of the landscape architect who designs the urban space. The re-birth as a cultural space of downtown owing to the efforts of the said cultural catalysts is meaningful.

Jens Jensen was an American landscape architect and early conservationist who pioneered a unique naturalistic landscape style. The purpose of the present study is to study Jensen's life, careers, design philosophy, and his contributions to the history of landscape architecture. Inspired by nature, Jensen worked closely with native plants, local materials, curvilineal and circular forms, and native scenery. His pioneering work in the Chicago's West Parks, including the design of Columbus Park and Humboldt, Garfield and Douglas Parks, was informed by his philosophical belief in the humanizing power of parks. In summary, first, Jensen played a prominent role in the creation of a unique native landscape style respecting regional landscape. Second, as a devoted conservationist and educator he organized conservation movements preserving landscape heritage and founded a education institution. Third, as a social reformer he emphasized the value of parks and nearby nature for urban citizens and children. Jensen's visions and philosophies have influenced on recent naturalistic landscape style and conservation efforts to preserve cultural landscape and natural environment.

Purpose Quality control used in laboratory help to sustain precision and accuracy consistently to ensure the Diagnostic and treatment for medical employee. To perform an evaluation in statistical manner, it is recommended to use different quality control material than calibrator from manufacturer, quality control material must include analyzed concentration perimeter, must use more than two different concentration materials and recommended to use materials to indicate the concentration in clinical use. However, currently used quality control material has limit of evaluation due to unconsidered concentration or improperly used to get clinical importance data. Therefore, we compared the value of quality control, DIACON Hormone Level 1, 2, 3 (Scantibodies, USA) and DIACON Tumor Level 1, 2, 3 which applied to clinical concentration range. Materials and Methods DIACON Hormone Level 1, 2, 3 (Scantibodies, USA) and DIACON Tumor Level 1, 2, 3 (Scantibodies, USA) that used materials and methods test to compare the result from five RIA testing institution and one institution that used Elecsys (ROCHE) and Architect (ABOTT) for each level. The reagent RIA kit that used in this experiment is followed by Table 2 and 3. Test has performed by instruction itself and follow by instruction. Results Among DIACON hormone result of twenty four items, level 1 have three items, level 2 have four items and level 3 have five items were out of manufacturer set up range based on the average value. Among DIACON tumor result of thirteen items, level 1 have three items, level 2 have four items and level 3 have five items were out of manufacturer set up range. Other result were inside of manufacturer range. Conclusion For quality control material, it is widely available in market, but it is limited for normal range which is only concerned in improper clinical value and difficult to evaluate important concentration area in terms of clinical analyze. In this experiment, we evaluate Hormone twenty three items and Tumor thirteen items with DIACON Hormone and Tumor (Scantibodies, USA) to resolve this limit and we could observe that it ca be substituted and used.
