The purpose of this study was to investigate the residents' actual usage at three rest areas and three playgrounds in an apartment complex. This study was conducted with field study in J apartment complex in Incheon from August 14 to August 30, 1998. According to the results of the study, there were more users in playgrounds than in the rest areas. The rest area near the place for the elderly in the complex was used mainly by the elderly females. The playground located near the main entrance of the complex was frequently used because it is the biggest one in size and has an enough space for playing. Furthermore, the condition of shading areas by trees and buildings influenced the rate of use of the residents. Therefore, to increase the usage rate of rest areas and playgrounds, they should be located near to the places which have community amenities and should have accessible entrance for residents. Landscape design of the apartment complex should be done with the plot plan of the complex simultaneously. Moreover, the number and the kinds of trees to be planted in the apartment complex should be considered carefully.

In this paper, the MFL (magnetic flux leakage) signals of complex defects on the underground gas pipeline are analyzed and their depths are estimated. Since closely-located defects (complex defects) affect each other, accelerate the progress of defection, and are finally combined to one (cluster), it's meaningful to differentiate complex defects from single defects by analyzing their characteristics. Various types of complex defects are characterized and analyzed by defining the safety distance for interference. 26 artificial defects are carved on the pipeline simulation facility (PSF) to analyze the characteristics of complex defect and demonstrate the accuracy of the proposed complex defect estimation. The proposed method shows average length error of 5.8 mm, average width error of 15.55 mm, and average depth error of 8.59%, respectively.

Unlike optical equipment, SAR(Synthetic Aperture Radar) has the advantage of obtaining images in all weather, and object detection in SAR images is an important issue. Generally, deep learning-based object detection was mainly performed in real-valued network using only amplitude of SAR image. Since the SAR image is complex data consist of amplitude and phase data, a complex-valued network is required. In this paper, a complex-valued ResNet network is proposed. SAR image object detection was performed by combining the ROI transformer detector specialized for aerial image detection and the proposed complex-valued ResNet. It was confirmed that higher accuracy was obtained in complex-valued network than in existing real-valued network.

Polymer concrete has more excellent durability, tensile strength, flexural strength and waterproof performance mechanically than normal concrete, and as it mixes as a polymer binding material, it can reduce the cement use amount. This study reviews fundamental properties of cement material mixed with complex polymer. As a result of this study, as percentage of complex polymer mix increases, flow value will decrease so that liquidity and compression strength will decrease. On the other hand, in case of flexural strength, when the mixture is 10%, it increases significantly more than OPC.

Poly(hydroxamic acid) resin beads were prepared and complexed with various metal ions. We used IR spectroscopy to investigate the structure of metal complex. It proved that the products formed by introduction of metal ions gave stable and colored complex. It was found that the resin bead as synthesized would be a good column packing material for continuous extraction. Energy dispersive spectroscopy was use to study the distribution of metal ions in the resin matrix. It could be tentatively concluded that adsorption and diffusion of metal ions in the chelating resins mainly depended on the loading of the resin matrix which indicated interacting sites with metal ions.

In general, the industrial complex is a place where factories of various industries are concentrated. It is only as efficient as it is designed. However, the risks vary as there are various industries. These features are also associated with various types of disasters. The dangers of natural disasters such as a typhoon, flood, and earthquake, as well as fire and explosions, are also latent. Many of these risks can make stable production and business activities difficult, resulting in massive direct and indirect damage. In particular, decades after its establishment, the vulnerabilities increase even more as aging and small businesses are considered. In this sense, it is significant to assess the vulnerability of the industrial complex. Thus analysing fire and explosion hazards as stage 1 of the vulnerability evaluation for the major potential disasters for the industrial complex. First, fire vulnerabilities were analyzed quantitatively. It is displayed in blocks for each company. The assessment block status and the fire vulnerability rating status were conducted by applying the five-step criteria. Level A is the highest potential risk step and E is the lowest step. Level A was 11.8% in 20 blocks, level B was 22.5% in 38 blocks, level C was 25.4% in 43 blocks, level D was 26.0% in 44 blocks, and level E was 14.2% in 24 blocks. Levels A and B with high fire vulnerabilities were analyzed at 34.3%. Secondly, the vulnerability for an explosion was quantitatively analyzed. Explosive vulnerabilities were analyzed at 4.7% for level A with 8 blocks, 3.0% for level B with 5, 1.8% for level C with 3, 4.7% for level D with 8, and 85.8% for level E with 145. Levels A and B, which are highly vulnerable to explosions, were 7.7 %. Thirdly, the overall vulnerability can be assessed by adding disaster vulnerabilities to make future assessments. Moreover, it can also assist in efficient safety and disaster management by visually mapping quantified data. This will also be used for the integrated control center of the N-Industrial Complex, which is currently being installed.

Multiple phosphorylation of the carboxy-terminal domain (CTD) of the largest subunit in RNA polymerase II (RNAP II) is thought to play an important role in the transcription cycle. The preinitiation complex in a partially purified complete transcription system suggested that RNA polymerase IIA containing unphosphorylated CTD is involved in complex assembly, whereas RNA polymerase IIO containing Ser and Thr phosphorylated CTD is not involved in preinitiation complex assembly. Recently a minimal transcription system was developed which requires chemically defined minimal components for its transcription: TBP, TFIIB, TFIIF, RNAP II and a supercoiled adenovirus-2 major late promoter (Ad-2 MLP). It would be using interesting to determine the consequence of CTD phosphorylation on preinitiation complex formation using the minimal transcription system. Contrary to the results from the partially purified complete transcription system, both RNA polymerase IIA and IIO are equally recruited in the preinitiation complex formation. The discrepancy may result from the two different assays used to determine complex formation, the use of chemically undefined complete and defined minimal transcription systems. This implicates that some factors in the complete transcription system are involved in the distinction between RNAP IIA and IIO in complex assembly. In addition multiple tyrosine phosphorylation of the CTD of RNAP II was prepared with c-Abl kinase and its recruiting ability in the preinitiation complex was examined. Compare with Ser and Thr phosphorylated RNAP IIO, Tyr phosphorylated RNAP IlOy forms a stable preinitiation complex in both the minimal and complete transcription systems. Based on these results, it seems that tyrosine phosphorylation of the CTD is important in the transcription cycle on the special subset of class-II promoter or has a different role in the transcription process.
