  • Recently, The government has been brought in the electronic document system. So, It's been increasing the job processing with the electronic approval and the distribution business. However because of the variety of the storage type of electronic document, it's expected many difficulties in the public-usage and etemity-preservation of the information later. also, There are several problems to manage electronic document system, for example, absence of the important function for managing records, etc. So, We propose the methodology as a way to solve several problems of managing electronic document in this paper. It grows the business which is produced in processing the electronic records management. The kind of document file produced by the government is various. Through introducing the standard format of document file, hereafter it has an effect on helpfulness in standardizing the electronic document system, and people recognize the situation of problem to append the important function of the preservation and usage for the electronic document system. The key task is to make the document system with keeping records and following functions according to the law of records management. As applying the standard electronic document system to manage records, the records of the processing section to the data center and then the records of the data center transfer to the government records and archives center. So, the records which be transferred can be preservative and available. The record, such as visual and auditory record which is not easy to digitalize, can be digitally preservative and available in the government records and archives center.

  • This study investigated the perceived significance of laboratory(lab) notebooks and the creation and maintenance of them from the perspectives of graduate students and professors in science fields. Semi-structured interviews of three professors and four graduate students were conducted. The interviewees were from three university laboratories of physics, chemistry and biological science. While professors perceived administrative continuity to be a reason for creating lab notebooks, students valued lab notebooks as a memory, and emphasized learning professional knowledge and skills through the recordkeeping practice. Students understood the ownership of lab notebooks and professors wanted to keep lab notebooks until they retire. Interviewees focused more on the content of lab notebooks rather than the form and the structure. They were also not willing to adopt an electronic lab notebook system. Students learned how to create lab notebooks through a course, their current or former academic advisors, seniors in the lab or well-written sample lab notebooks. In particular, students have learned how to create lab notebooks within their laboratories, which are considered to be communities of practice. In this sense, professors responsible for managing laboratories play an important part in teaching students the recordkeeping practice. University archives should also be more concerned with managing and preserving lab notebooks created from their universities.

  • Although the soil nailing method is generally used as a gravity grouting, the development and application of pressurized grouting method has recently increased to address the problem of joint generation and filling due to grouting. Pressurized grouting of the soil nailing method is generally used in combination with ordinary portland cement and water. In the field, the cement is mixed with the rapid setting cement to reduce curing time because ordinary portland cement takes more than 10 days to satisfy the required strength. In this study, uniaxial compression tests and laboratory tests were carried out to confirm the efficiency of the grouting material according to the mixing ratio of rapid setting cement. The mixing ratio of 30% grouting satisfies the required strength within 7 days and satisfies the optimum gel time. As a result of the laboratory test with granite weathered soil, the reinforcing effect was confirmed to be 1.5 times as compared with the gravity type at an injection time of 10 seconds and a strain of 15%. The friction resistance increases linearly with the increase of the injection time, but it is confirmed that the friction resistance decreases due to the hydraulic fracturing effect at the injection time exceeding the limit injection pressure. Numerical analysis was performed to compare the stability of slopes not reinforced with slopes reinforced with gravity and pressurized soil nailing.

  • The purpose of this study is as follows: First, to analyze the spatial structure of Jeju by analyzing the rate of parking demand and supply; Second, to determine the parking service imbalance between regions; and third, to elucidate the causes of this spatial structural parking service imbalance and provide effective measures. Due to the rapid population and tourism growth, Jeju is suffering from traffic congestion and serious parking problems. For this, the ways to efficiently utilize the existing parking spaces were identified through spatial structure analysis based on the parking demand and supply in the Jeju area. As short-term policy, the following changes were proposed: switching to small-scale eup or myeon blocks of parking space, use of shared parking system, and repairing side streets in residential areas. As mid-to-long-term policy, it is linked to other means of transportation as follows: parking demand management policy through modal share by reorganizing public transportation routes or expanding traffic facilities; securing park-and-ride lots; and different parking pricing for different time periods. To implement these policies, each area of the public sector, private sector, and private-public partnership should develop the bond of sympathy by areas and participants.

  • As a 'Senior Citizen' by applying an active theory based on a role model, elderly volunteers may seek to impart health to the local communities through volunteer activities. In addition, the strategies for promoting the elderly participation volunteering actions may apply with the lifelong education/learning model for citizenship development, which intends to expand the elder volunteer activity participants and the areas of volunteering actions. In this study, we attempted to find out how volunteering fieldworkers experience and perceive volunteer-promoting strategies for senior volunteers drawn from previous literatures and studies on promoting elderly volunteer actions. For the purpose of the study, we conducted in-depth interviews with 12 fieldworkers who worked senior-welfare centers and volunteer centers in Seoul and Kyeong-gi area. We used the directed-content analysis, which categorized 12 themes/categories commonly mentioned from previous literatures and studies. Within these categories, the analysis was made to derive issues and improve promoting strategies specified from the interviewees. The outcomes of the study included the insights regarding what promoting-strategies might be necessary to enrich existing senior volunteer actions. The study highlighted not only reviews volunteer fieldworkers' current experiences with senior volunteers but also barrier and practical suggestions for the continuous advances of senior volunteer programs and strategies.

  • The Riparian Buffer Zone(RBZ) is a sustainable social-ecological system created in the middle zone between water and land. For the RBZ, close communication with the local community is important, and it is necessary to promote it as a communicative environmental planning process. In this study, for the RBZ project, three strategies are presented as a communicative act to understand and implement planning. First, government-led projects were avoided and improved to a process in which citizens and stakeholders participated together, centered on local partnership. Second, it was intended to introduce design criterias in terms of enhancing the function of ecosystem services that citizens can sympathize with, and to increase acceptance and awareness through the planning of preferred spaces and facilities. Third, after a balanced plan for habitats, water cycle-based ecological environment, ecological experience and open space, citizens felt the restoration effect and value as an ecological resources, and a system was prepared to participate in the operation and management. This study will work as a process model based on citizens's participation. In addition, it will be possible to provide lessons for the change of the policy paradigm for the RBZ and the implementation of similar projects in the future.

  • Ground subsidence shows a mechanism in which the upper ground collapses due to the formation of a cavity due to the movement of soil particles in the ground due to the formation of a waterway because of damage to the water supply/sewer pipes. As a result, cavity is created in the ground and the upper ground is collapsing. Therefore, ground subsidence frequently occurs mainly in downtown areas where a large amount of underground facilities are buried. Accordingly, research to predict the risk of ground subsidence is continuously being conducted. This study tried to present a ground subsidence risk prediction model for two districts of ○○ city. After constructing a data set and performing preprocessing, using the property data of underground facilities in the target area (year of service, pipe diameter), density of underground facilities, and ground subsidence history data. By applying the dataset to the machine learning model, it is evaluated the reliability of the selected model and the importance of the influencing factors used in predicting the ground subsidence risk derived from the model is presented.

  • In ancient Egypt, temples were not only religious sanctuaries but also community centers. One of the core spaces created in the temple is the facility where priests and scribes copied and preserved texts on papyrus and other media. Its common designation was 'pr-mḏȝ'(House of Books) and the 'per-(nw)-seshw'(House of Scrolls). The general term used during that time was 'Per Ankh', and the modern term for it is 'temple library'. Therefore, this study first identified the character and identity of the Per Ankh attached to the temple, and then traced whether it is appropriate to designate 'healing place of the souls' depicted on the hypostyle hall(Per Ankh) in the Ramesseum(mortuary temple) built by Ramses II of the New Kingdom as a library. As a result, Per Ankh, a hieroglyph combining the Per(house) and Ankh(life), was revealed to be a multi-purpose complex facility consisting of a learning and research center, a treatment and healing center with medical facilities and sanatoriums, a religious ceremony and a center for the celebration of eternal life, a scriptorium and a library. Therefore, the traditional argument that Per Ankh refers to a library cannot be justified. In the same context, the inscription 'Ψυχῆς ἰατρεῖον' on the doorplate of the hypostyle hall of the Ramesseum, which was first introduced by Greek historian Hecataeus of Miletus in the 4th century BC, was translated into Latin as 'Psychēs Iatreion' by Diodorus Siculus in the 1st century BC and described as the motto of the sacred library. However, Psyche is the goddess of Greek and Roman mythology, and Iatreion means hospital(clinic, healing center) and pharmacy, so Per Ankh in the Ramesseum is a space to heal the soul of the pharaoh (Ka). Therefore, 'Psychēs Iatreion = library' is a distortion and a mistranslation. It is not the motto of the library, but a metaphor for the Per Ankh.

  • Lead toxicity was evaluated in forty-five cats on a balanced diet, treated with 0(control), 10, 100(low), 1, 000, 2, 000 and 4, 000(high)ppm of lead acetate orally on a body weight basis. The objectives were to describe the gross and histopathologic changes and to demonstrate what tissue lead concentrations correlate with the known dosages of lead. In subclinical lead toxicity, greater than 80% of the absorbed lead was deposited in the bone, whereas in more acute lead toxicity, 42% of absorbed lead was deposited in the bone and 36% and 20% of absorbed lead was deposited in the kidneys and in the liver, respectively. No gross lesions were found in the nervous system. Yellow-brown colored livers appear to be associated with lead toxicity. Neuronal necrosis in the cerebrum was the most predominant histopathologic finding. Astrocytic proliferation in the cerebral gray matter was observed in 1 high dose cat. Gliosis was noted in the cerebral cortex of 6 high dose cats. Two high dose cats had demyelination in the deepest layer of the cortical gray matter of the cerebrum. Extravasation of red cells and cavitation around the vessels were found in the cerebrum of 1 high dose cat. Six high dose cats had degeneration of Purkinje cells in the cerebellum. The microscopic findings in the peripheral nerves were ambiguous. In more acute toxicity, the cats had lead inclusions in the epithelial cells of proximal tubules of the kidneys of 7 cats and hepatocytes of the liver of S cats. These inclusions could be seen wlth H&E, but were more prominent with orcein staining. Two high dose cats had granulomas and connective tissue hyperplasia between tubules of the kidneys. Periportal hepatocyte vacuolization was observed in the liver of 22 cats. Vacuolization of seminiferous tubules and a reduced number of spermatogonia(indicative of reduced spermatogenesis) were found in the testis of 5 treated cats. Cystic ovaries were observed in 3 high dose cats and poor development of oogonia was found in 2 cats. The diagnosis of lead toxicity in cats can be suspected on the basis of the histopathologic lesions described, and can be of value in contributing to a diagnosis. A reliable diagnosis of lead poisoning can be helped utilizing tissue lead analysis(post molten)

  • We have developed a spherical FCT code in order to simulate the interaction of supernova remnants with stellar wind bubbles. We assume that the density profile of the supernova ejecta follows the Chevalier mode1(1982) where the outer portion has a power-law density distribution($\rho{\propto}\gamma^{-n}$) and the SN ejecta has a kinetic energy of $10^{51}$ ergs. The structure of wind bubble has been calculated with the stellar mass loss rate $\dot{M}=5\times10^{-6}M_{\odot}/yr$ and the wind velocity $\upsilon=2\times10^3$ km/s We have simulated seven models with different initial conditions In the first two models we computed the evolution of SNRs with n=7 and n=14 in the uniform medium The numerical results agree with the Chevalier's similarity solution at early times. When all of the power-law portion of the ejecta is swept up by the reverse shock, the evolution slowly converges to the Sedov-Taylor stage. There is not much difference between the two cases with different n's The other five models simulate SNRs produced inside wind bubbles. In model III, we consider the SN ejecta of 1.4 $M_{\odot}$ and the radius of bubble ~2.76 pc so that ratio of the mass $\alpha(=M_{W.S}/M_{ej}$ is 2. We follow the complex hydrodynamic flows produced by the interaction of SN shocks with stellar shocks and with the contact discontinuities, In the model III, the time scale for the SN shock to cross the wind shell $\tau_{cross}$ is similar to the time scale for the reverse shock to sweep the power-law density profile $\tau_{bend}$. Hence the SN shock crosses the wind shell. At late times SN shock produces another shell in the ambient medium so that we have a SNR with double shell structure. From the numerical results of the remaining models, we have found that when $\tau_{cross}/\tau_{bend}\leq2$, or equivalently when $\alpha\leq50$, the SNRs produced inside wind bubbles have double shell structure. Otherwise, either the SN shock does not cross the wind shell or even if it crosses at one time, the reverse shock reflected at the center accelerates the wind shell to merge into the SN shock Our results confirm the conclusion of Tenorio-Tagle et a1(1990).
