  • In the wake of categorizing the design changes occurred during the period from 2004 till the first half of 2006 in Choongcheong province area, based on purpose and reason of design changes identified by the Korea National Housing Corp, it included 11 types such as the image of the apartment complex, scenic elements, consideration by the user, prevention of the defect, constructability, site conditions, incompatibility between the activities, superordinate standard, prevention of civic complaints, design details and others, along with 47 subordinate elements. And the evaluation intended to identify the corelation between the number and time of design change approval, frequency and scale of design change by type and the cost variations indicated that; firstly, enhancing the image of the apartment complex proved to be the main reason for design changes, accounting for 22% in terms of frequency and 54.9% in terms of cost variation. Secondly, the higher the increase in cost by design change aimed at improving the image of the complex, the lower the decrease in cost by design change for uncertain reasons, dubbed the inverse proportional relations, indicating that the design changes for uncertain reasons were mostly aimed at reducing the construction cost. Thirdly, with regard to the number of design change approval and the time of the initial approval, twice or less and 90 days or less before completion of the construction work, respectively, accounted for $52{\sim}53%$, indicating the design change deliberation and approval tended to have been carried out collectively in the form of ex post facto approval, which seemed to be attributable to the attempt of reducing the construction cost or budget problem, as a result of comparing with the cases in which the cost was reduced.

  • Most studies of Korean Newspaper in historical view have focused on the news writing form and editorial practice. Those studies have much rely on the memories of ex-journalist or the impression of scholars. So this study aims to give the concrete figures of news writing forms and editing practices in 1920-30's by investigating Kim Dong-Seong's activities as a journalist. He was a first journalist who studies journalism. He studied journalism during his stay in the Ohio State University as an english department student. After he came back to Seoul, he worked at the Dong-A Il Bo as an one of the first publish members. His activities as a journalist have much important meanings because of his varied works and careers. He also wrote a practical affair book for reporters which was the first book in Korea. As a result of research about Kim Dong-Seong's activities in 1920-30's, the feature of edit practice in 1920's had much emphasis not only on the headline but on the relation between type and print, and at the same time the combination of news or the change of typography was one of methods which make the editing more variety. News materials were collected varied news sources and legworks by reporter. These results show us that such a news reporting practice in 1920-30's is similar co the contemporary.

  • The guarantee of citizens' safety from crime is the reason for a nation's existence according to the social contract, and it is also a salient task in securing the citizens' right to the pursuit of happiness, which is a constitutional right expressing the nation's duty to its citizens. First, a procedure must be made mandatory that corresponds to the Miranda rule applied during the arrest of criminal suspect, which verifies whether there exists a risk of retaliatory crime to the victim of crime, crime reporter, or witness following their report of a crime or testimony. A measure to punish those who violate this should be devised. The second is the improvement of related laws and systems, such as expanding the scope of persons subject to protection from retaliatory crimes under the current law and strengthening information protection. Third, a retaliatory crime risk evaluation index must be developed, and the evaluation results must be quantified to clearly state measures and responsibilities, in detail, for personal safety at each level of intensity. The fourth is the expanded implementation of proactive personal safety measures for victims of crime and witnesses, as well as the development and application of advanced techniques. The last is a change in the perception s of those working for the judicial body. From the initial investigation stage of the crime to the diagnosis regarding the possibility of retaliation perpetrated on an ex-convict through psychological tests, systems of general cooperation, and mutual assistance must be established.

  • The purpose of this study is to research the effect of using analogies in high school earth science classes. According to the usage of TWA model, three types of teaching strategies were developed: text developer-generated, teacher-generated, and student-generated analogies. The model described in this paper began with a task analysis of highschool science textbooks for grade 10 to identify how the textbook authors used analogies to explain plate tectonics concepts. In this study, 210 students were sampled from first graders of high school. After 7 classes, the consciousness of students was investigated with questionnaires. The results are as follows: 1. Many plate-tectonics analogies are used in high school science textbooks (total 25). Teachers and authors construct effective analogies to help students build on their relevant knowledge by applying it to new knowledge acquired from textbooks. 2. Analysis of the data indicate that instruction using student-generated analogies was more effective than others. But in the class in conveying complicated concepts (ex. transform fault), teacher-generated instruction was effective. Teachers need to be aware of the weakness of using analogies in order to select the most appropriate analogies. 3. Making analogies in general, as well as using analogies have systematic steps. Analogies should be used after considering student's preconception, teacher's consciousness and text author's intention to use analogies as powerful instructional tools.

  • This paper developes an integrated environment CAD system that can design and implement an accurate and cost-effective FLC automatically. For doing this, an integrated development environment (IDE) (called FADIS; FLC Automatic Design and Implementation Station) is built by the seemless coupling of many existing. CAD tools in an attempt to the FADIS performs various functions such that (1) i~utomatically generate the VHDL components appropriate for the proposed FLC architecture from the various design parameters (2) simulate the generated VHDL code on the Synopsys's VHDL Simulator, (3) automatically compiler, (4) generate the optimized, placed, and routed rawbit files from the synthesized modules by Xilinx's XactStep 6.0, (5) translate the rawbit files into the downloadable ex- [:cution reconfigurable FPGA board (VCC's EVCI), and (7) continuously monitor the control status graphically by communicating the FLC with the controlled target via S-bus. The developed FADIS is tested for its validity by carrying out the overall procedures of designing and implementing the FLC required for the truck-backer upper control, the reduction of control execution time due to the controller's FPGA implementation is verified by comparing with other implementations.

  • Stable Compression Fractures(SCF hereafter) are most often caused by trauma such as traffic accidents. These SCFs usually occur in the thoracic and lumbar regions of the spinal cord. Human life spans have increased as a result of medical advances, which in turn has led to an increase in the elderly population. SCFs are divided into the categories of stable and unstable. The categories are determined through X-rays and P/Ex tests. The D.I.T.I. is then used to diagnose the severity and prognosis of the fracture injuries, and it allows an objective evaluation of the symptoms. This author researched 40 patients who were treated at Wonkwang University Oriental Medical Center from October 1995 to December 1996. The patients were diagnosed by X-ray as having SCFs and treated primarily with acupuncture. Both the changes in D.I.T.I. and patients' self-diagnoses of their conditions before and after treatment yielded the meaningful results which have been presented here. 1. 75% of those who suffer from Stable Compression Fractures are 60 years of older. Of those, the ratio of male to female is 1 to 4. This is due in part to the fact that many elderly women seek Oriental medicine treatment for conditions associated with advanced age. 2. 53.3% of these injuries occurred between T11 and L2. 3. 65% of patients were hospitalized for 10 to 29 days, and then able to be treated on an outpatiens basis. 4. The D.I.T.I. results showed 50% below $0.2^{\circ}C$, 30% between 0.3 and $0.5^{\circ}C$, 10% between 0.5 and $0.7^{\circ}C$, 10% between 0.7 and $0.9^{\circ}C$, and 0% over $0.9^{\circ}C$. 5. The results of treatment using Modified Evaluation System in Thoracolumbar Vertebral Fractures Method showed that 55% of patients achieved excellent recovery and 40% achived good recovery. After comparing the D.I.T.I. results before and after treatment, we found 50% of patients showed excellent recovery $({\Delta}T{\leq}0.2)$ and 40% showed good recovery$(0.2<{\Delta}T{\leq}0.5)$.

  • Periodontal ligament (PDL) is the connective tissue located between the tooth root and alveolar bone. In a previous study, PDLs22 was isolated as a PDL-specific gene by using subtractive hybrid-ization between cultured PDL fibroblasts and gingival fibroblasts. It was also suggested that PDLs22 plays important roles in the development, differentiation and maintenance of periodontal tissues. However, little is known about functional study of PDLs22 using recombinant protein in PDL fibroblast differentiation and periodontium formation. In this study, in order to produce the PDLs22 recombinat protein, PDLs22 expression vector were constructed and expressed its protein in various host cell and temperature conditions. The results were as follows: 1. PDLs22 protein was not strongly expressed In the induction system using pRSET-PDLs22 construct. 2. When the BL21(DE3) pLysS was used as a expression host, PDLS22 protein was strongly ex-pressed in the induction system using pHCEIIBNd-PDLs22 construct. 3. The PDLs22 protein was recognized at a molecular weight of 28 kDa in western blots. 4. Almost of the expressed PDLs22 protein was not soluble and observed like as inclusion body. 5. The protein solubility was not improved after modification of induction time and temperature during PDLs22 protein production. In this study, the system for the PDLs22 protein production was connstructed. However, the re-results suggest that further studies will be needed to produce the considerable amount of PDLs22 re-combinat protein, which can use for the periodontal regeneration.

  • This study shows the meaning on context of social work practicum that college students have experienced. It reveals to find a essence of social work practicum based on college students through free variation. They met a "high barrier" from the beginning of social work practicum. There were "confused boundary of role as well as work". "Dilemma" has been accessed, so they felt various emotions for social work and social worker to be able to exist. "Various practice place" meant to continue as a multi-player with a weak appearance and confront for time as who he/she is. This was connected to whole life time for individually. Disclosure was as below. identity as a social worker(to be) was consisted beyond interaction between student and supervisor. Organization of social work practicum was considered when they had taken a part in. Gap must find out to be disappeared between ideal things and real things about social work practicum. Ideal type of college education for social work as well as whole education for all were needed.

  • Background : The immune responses mediated by CD8+T cells are known to be significant in controlling M. tuberculosis infections. In order to determine the role of cytotoxic CD8+T cells in the protective immune mechanism in latently infected subjects, this study examined whether or not the cytotoxic immune responses of CD8+T cells specific to the M. tuberculosis somatic antigens are induced in BCG vaccinated healthy subjects. Methods : Cytotoxicity and $IFN-{\gamma}$ elispot assays were used to investigate the activities of CD8+T cells specific for the $thyA_{30-38}$ peptide epitope in circulating peripheral blood mononuclear cells (PBMC) from BCG-vaccinated HLA-A*0201 and A*0206 subjects. Results : The results indicate the cytotoxic and $IFN-{\gamma}$ immune responses of CD8+T cells specific for $thyA_{30-38}$ were induced in BCG vaccinated healthy subjects. Conclusion : The cytotoxic and $IFN-{\gamma}$ responses by CD8+T cells specific for the M. tuberculosis somatic antigens are induced in BCG-vaccinated subjects, and appear to be involved in the protective immune mechanism in latently infected people against a M. tuberculosis infection.
