  • Bus service is easily adjusted to accommodate the changed demand. Despite the flexibility of that, its relocation should overcome the following problems: first, Bus line rearrangement should consider the balance between the demand and the supply to enhance the transit equity among the users scattered around the area that supply against demand imbalances. Second, the existing demand analysed is to crude since the demand was analysed based on TAZ. mainly based on the Dong unit. Utilization of the GWR and GIS-T data can resolve the problem. In this paper, the limitation of the conventional transit demand analysis model is overcome by deploying the GWR model which identifies the transit demand based on the geographic relation between the service location and those of the users. GWR model considers the spatial effect of the bus demand in accordance with the distance to the each bus stops using SCD(Smart Card Data) and BIS(Bus Information System). This demand map was then superimposes with the existing bus route which identified the areas where the balance between demand and supply is severly skewed. since the analysis was computed with SCD and BIS at every bus stops. the shortage and surplus of bus service of entire study area could computed. Further. based on this computational result and considering the entire bus service capacity data. Bus routes optimization from the oversupplied areas to the undersupplied area was illustrated thus this study clearly compared the benefits the GIS.

  • The purpose of this study is to research pre-service chemistry teachers' inquiry ability and perception on inquiry by analyzing their argument structure. Nine graduating senior students have participated in this study. They have experimented with mass change during state change, which is included in 7th grade science textbook. We have analyzed pre-service teachers' experimental reports using Toulmin's argument model. Also, we have researched their views on science and experiments through questionnaires and semi-structured interviews. As results show, various factors have affected pre-services' argument structures; lack of science knowledge and inquiry ability, belief about error, and additive data. This study shows that pre-service teachers' inquiry abilities is insufficient, and it is necessary to review rearrangement of pre-service science teacher curriculum in order to offer inquiry experiments in teacher education program.

  • The statistics of disaster and safety control which have been produced by NEMA(National Emergency Management Agency) and other related agencies have some problems which show redundancies and the lack of connections. These problems can result in disbelief of disaster-management related policies and cause uncertainties on standardization. One of the main problems is caused by the lack of an integrated system that can coordinate available statistical resources. The objectives of this paper are to propose possible ways for the rearrangement of statistics categories, the improvement of statistics indicators and the integration of statistics of disaster and safety management based on the improvement of related laws and regulations. Through the integrated system for an efficient production of disaster and safety-related statistics, it will be possible to establish more accredited disaster-management policies based on the scientific statistics and international standard.

  • This paper reviewed present status of school health program in Korea to seek. The improvement of health of school children. The results are summarized from reviewing publications of school health and survey data from trainees for principals of primary and middle school at Korea National University of Education during Jun. 17 to Aug. 13, 1987. The major recommandations for the improvement of school health program in Korea of this study are as follow: 1. Reformation of School Health Organization It is hard to activate effective school health program without reformation of school health organization in the Ministry of Education. School health section in MOE should be reorganized for the planning, operation and evaluation of school health program. School health committee in MOE and Provincial Board of Education should be established by the health and education professions. 2. Appointment of school physician and recruitment of school nurse: School health center in Office of City/Gun Education should be established for increasing the utilization of school physician, and school nurse should be appointed for 3 - 4 schools in same area. 3. Improvement of school health education: 1) Curricula of physical education of teachers College/University should be rearrangement for school health education. 2) Role of school nurse as a health educator in school should be extented. 3) In-service training for health education should be done for teachers of physical education. 4) Professional health teacher should be trained independently from physical education in College of Education and Teachers College. 4. Revision of school health law and regulations: Present school health law and regulations should be revised by the recommendations of experts on school health.

  • A large scale of riverside rearrangement has been recently done in the major rivers in Korea. So inundation possibility in agricultural area closed by these rivers has been higher than the possibility a few years ago. However, land use in this area has not been adjusted to a change of this situation near the rivers. Therefore, when typhoon or heavy rain is happened on this area, it can cause a large damage in agricultural area. This study analyzed inundation potentiality in agricultural area at Ibang-myeon, Changnyeong-gun, Kyeongnam-province, Korea by using the logistic regression model and the piecewise regression model. The first thing we did was to transfer the inundation area per elevation to the accumulated inundation area per elevation. This accumulated inundation area per elevation as an distribution function could be described by the logistic regression model(LRM), and piecewise regression model(PRM) could make it much more accurate to analyze the inundation area per elevation. As a result, the regression models derived from LRM and PRM showed $R^2$ over 0.950. The models derived from LRM and PRM in Ibang-myeon noted that frequently inundated area(FIA) was shown up to 12.12m in elevation, and potentially inundated area(PIA) was shown up to 14.60m in elevation. In FIA, regular agricultural activity would be impossible. And It would be not easy to continue the regular agricultural activity in PIA. So, this land should be rearranged to be used for a buffer zone for ecosystem protection, landscape conservation and things like that in riverside.

  • The complete mitochondrial genome of a troglobite millipede Antrokoreana gracilipes (Verhoeff, 1938) (Dipolopoda, Juliformia, Julida) was sequenced and characterized. The genome (14,747 bp) contains 37 genes (2 ribosomal RNA genes, 22 transfer RNA genes and 13 protein-encoding genes) and two large non-coding regions (225 bp and 31 bp), as previously reported for two diplopods, Narceus annularus (order Spirobolida) and Thyropygus sp. (order Spirostreptida). The A + T content of the genome is 62.1%, and four tRNAs ($tRNA^{Ser(AGN)}$, $tRNA^{Cys}$, $tRNA^{Ile}$ and $tRNA^{Met}$) have unusual and unstable secondary structures. Whereas Narceus and Thyropygus have identical gene arrangements, the $tRNA^{Thr}$ and $tRNA^{Trp}$ of Antrokoreana differ from them in their orientations and/or positions. This suggests that the Spirobolida and Spirostreptida are more closely related to each other than to the Dipolopoda. Three scenarios are proposed to account for the unique gene arrangement of Antrokoreana. The data also imply that the Duplication and Nonrandom Loss (DNL) model is applicable to the order Julida. Bayesian inference (BI) and maximum likelihood (ML) analyses using amino acid sequences deduced from the 12 mitochondrial protein-encoding genes (excluding ATP8) support the view that the three juliformian members are monophyletic (BI 100%; ML 100%), that Thyropygus (Spirostreptida) and Narceus (Spirobolida) are clustered together (BI 100%; ML 83%), and that Antrokoreana (Julida) is a sister of the two. However, due to conflict with previous reports using cladistic approaches based on morphological characteristics, further studies are needed to confirm the close relationship between Spirostreptida and Spirobolida.

  • Apoptotic signals are typically accompanied by activation of aspartate-specific cysteine proteases called caspases, and caspase-3 and -7 play crucial roles in the execution of apoptosis. Previously, using the proteomic approach, protein disulfide isomerase (PDI) was found to be a candidate substrate of caspase-7. This abundant 55 kDa protein introduces disulfide bonds into proteins (via its oxidase activity) and catalyzes the rearrangement of incorrect disulfide bonds (via its isomerase activity). PDI is abundant in the ER but is also found in non-ER locations. In this study we demonstrated that PDI is cleaved by caspase-3 and -7 in vitro. In addition, in vivo experiment showed that it is cleaved during etoposide-induced apoptosis in HL-60 cells. Subcellular fractionation showed that PDI was also present in the cytosol. Furthermore, only cytosolic PDI was clearly digested by caspase-3 and -7. It was also confirmed by confocal image analysis that PDI and caspase-7 partially co-localize in both resting and apoptotic MCF-7 cells. Overexpression of cytosolic PDI (ER retention sequence deleted) inhibited cell death after an apoptotic stimulus. These data indicate that cytosolic PDI is a substrate of caspase-3 and -7, and that it has an anti-apoptotic action.

  • In modern society, creation and distribution of multimedia contents is being actively conducted. These multimedia information have come out the enormous amount daily, the amount of data is also large enough it can't be compared with past text information. Since it has been increased for a need of the method to efficiently store multimedia information and to easily search the information, various methods associated therewith have been actively studied. In particular, image search methods for finding what you want from the video database or multiple sequential images, have attracted attention as a new field of image processing. Image retrieval method to be implemented in this paper, utilizes the attribute of corner patches based on the corner points of the object, for providing a new method of efficient and robust image search. After detecting the edge of the object within the image, the straight lines using a Hough transformation is extracted. A corner patches is formed by defining the extracted intersection of the straight line as a corner point. After configuring the feature vectors with patches rearranged, the similarity between images in the database is measured. Finally, for an accurate comparison between the proposed algorithm and existing algorithms, the recall precision rate, which has been widely used in content-based image retrieval was used to measure the performance evaluation. For the image used in the experiment, it was confirmed that the image is detected more accurately in the proposed method than the conventional image retrieval methods.

  • The aim of this study was to evaluate the diagnostic value of fine needle aspiration cytology (FNAC) for the assessment of palpable enlarged lymph nodes. The authors reviewed the results of 1,346 FNACs of palpable enlarged lymph nodes performed at Pusan National University Hospital from 1998 to 2004. Of the 1,346 cases, 1,265 (94.0%) were satisfactory and 81 (6.0%) unsatisfactory. Cytologic diagnoses were judged in 488 cases, based on subsequent histologic diagnoses, clinical follow up, or both. Global results for all malignancies (lymphoid and non-lymphoid neoplasms) based on cases with final diagnoses, showed a sensitivity of 87.4% and a specificity of 98.7%. The overall diagnostic accuracy was 93,2%, and the false negative rate reduced from 12,6% to 7,3% when lymphomatous cases were excluded. The annual data for this period showed that the number of diagnostic lymph node biopsies and the rate of inadequately sampled material markedly decreased. Gene rearrangement studies for IgH and TCR ${\gamma}$ were helful in 30 cases. FNAC is a useful initial diagnostic procedure for the evaluation of palpable enlarged lymph nodes. However, the technique should be assisted by the appropriate ancillary studies and by proper interpretation by a cytopathologist.

  • This study aims to effective survey on actual condition for impact and vulnerability assessment on climate change in agriculture and rural community (limited to rural water and agricultural infrastructure, Paragraph 3, Article 2 of the Rearrangement of Agricultural and Fishing Villages Act) entrusted to Korea Rural Community Corporation based on the Law (Paragraph 2, Article 47 of the Framework Act on Agriculture, Rural community and Food industry). The results are summarized as follows. The rural water was divided into three categories (abnormal climate, water use, and flood control), and 31 indicators were selected. The reservoirs were divided into four categories, and 20 indicators were selected. The pumping stations were divided into two categories, 7 indicators, and the drainage pump stations were divided into two categories, 5 indicators were chosen. A survey on actual condition of each indicator was conducted and the result of the impact assessment was calculated. The 65 rural water showed values ranged from 0.855 to 1.308. The reservoir ranged from 0.966 to 23.338 as a result of the impact assessment on the 16 indicators. The pumping station was able to calculate the results of the safety inspection and the thorough safety inspection, and the drainage pump station was able to calculate only the result of the safety inspection. It is judged that it will be necessary to secure and analyze data on indicators with no data in the future. The results of this research can be utilized as baseline data that can deal with climate change preemptively.
