Desktop Documentary is a new documentary mode which uses a screen capture technology to complete the multitasking process of the creator who searches in the Internet Open Archive instead of shooting with a camera and remixes the selected multimedia contents using a computer interface. In this paper, we explore the desktop documentary that transforms potential archives into database narratives in the new media environment, converts cinematic mise-en-$sc{\grave{e}}ne$ into computational mise-en-interface, and transcends the boundaries between creation and criticism through creative mechanism as curation through stream of consciousness. We also examine the concept, type and characteristics of the desktop documentary which emerges since 2010s as an experimental attempt of new media art, a new hybrid genre of mainstream horror film, a new mode of fiction film, a new mockumentary style, and a new form of video essay and audiovisual critique.

This paper attempts to analyze the changes of the contents in foreign area research carried out by Korean geographers, and discuss the task of the new regional geography in a global-local context. As compared with domestic area research, only a scant of foreign area research has been carried out. In the 1990's, the research interests are paid to how an open economy affects the regional economy, especialy the production technique, division of labor, industrial mix, market strategy, industrial location and organization, and so on. Unfortunately, however, the boundaries between economic geography and regional economy are gradully disappearing.

To nurture skilled IT professionals required in the 21st information society, we have been faced to the need of learner-centered open lifelong education through the e-learning system that crosses the boundaries of time, space and geography. The object of this research is primarily as-is analysis of the IT contents in present cyber institutions, then making out the basic research data by to-be analysis and international standardization trend through benchmarking. Eventually this research intends to produce a prototype of the contents especially for the subjects related to the IT which is based on the modeling of e-Learning standard contents development model. It is possible that the final output of this project is used for the contents producing and operating data in cyber universities and institutions. This output also enhances the international competitiveness by the standardization and presents a standardized guideline to the domestic cyber education institutions.

Major Royal Jelly Protein cDNAs of Apis cerana (AcMRJP) were cloned and characterized. The open reading frames (ORFs) of the AcMRJP1 and AcMRJP2 genes were 1302 and 1392 nucleotides, encoding 433 and 463 amino acid residues, respectively. The sequence divergences between AcMRJP1 and AcMRJP2 and their corresponding protein families in A. mellifera were 0.0618 and 0.0934 at the nucleotide level and 0.0912 and 0.1438 at the protein level, respectively. Phylogenetic analysis supports the orthologous similarity between these proteins. The deduced amino acids indicated high essential amino acid contents of AcMRJP1 and AcMRJP2 (47.5 and 44.8%, respectively). The genomic organization of both AcMRJP1 and AcMRJP2 was determined. Both the AcMRJP1 (3663 bp) and AcMRJP2 (3963 bp) genes contained six exons and five introns, where all boundaries conformed to the GT/AG rule. AcMRJP1 and AcMRJP2 cDNAs were cloned into pET17b, and both the recombinant (r) AcMRJP1 (47.9 kDa) and rAcMRJP2 (51.7 kDa) were expressed in the insoluble form. Western blot analysis and N-terminal sequencing of the solubilized proteins revealed successful expression of rAcMRJP1 and rAcMRJP2 in vitro. The yields of the purified rAcMRJP1 and rAcMRJP2 were approximately 20 and 8mg protein per liter of the flask culture, respectively.

The study aims to prove the raison d'etre of public libraries in urban regeneration paradigm. Life SOC Plan is one of South Korea's urban regeneration policies. Public libraries are considered important in life SOC Plan because public libraries are "Social Anchors". Social Anchor is space-time-bounded place that accelerates diverse people's interactions. Social Anchor makes collective identity that supports production of social capital. Public libraries are institutions producing social capital but have weak collective identity because their missions(open, sharing, equality of information) don't allow boundaries and membership. The study conducted literature reviews and case studies to confirm how collective identity of public libraries strengthens. As a result, the study confirmed that renovating under-used space based on urban regeneration paradigm makes place identity of the under-used space to collective identity of public libraries. Thus, constructing public libraries by renovating under-used space is Social Anchor formation model based on urban regeneration paradigm.

This study aimed to identify orientations for the development of the community by establishing desirable aesthetical environments and reorganizing the residents' communal way of life through the implementation of village art projects. To investigate how the implementation of village art projects influence community and communication, the author analyzed changes in walls made by the implementation of actual projects in Anhyeon Village in Gochang, Dongpirang in Tongyeong, and Byeolbyeol Village in Yeongcheon. The community was analyzed from the view points of locality, communal ties, and communication. The results showed that Anhyeon Village in Gochang expressed its locality with chrysanthemum, poems and local figures. Similar walls were built across the village to strengthen ties among the residents, and portraits used as doorplates represented communication among them. Various paintings of seas, flowers, and poems were seen in Dongpirang in Tongyeong, which were thought to be representations of its locality and the friendliness of hometown in the less favoured area. Wall paintings played pivotal roles in this village to impart to the residents essentials that should be kept to eliminate inner walls in their minds and ensure open communications. In Byeolbyeol Village in Yeongcheon, locality was presented with common farm village landscapes in various materials, patterns and formativeness. Village-wide reinforcement contributed to strengthening ties in the community rather than forming boundaries against outside worlds. Cultural and artistic elements structured mental walls that made people not aware of the presence of physical walls.

The typical blasting method adopted in Pasir Coal Mine is a surface blasting technique with a single free face. It means that there is only one free face, which is usually the ground surface. This kind of blasting method is easy to use but inevitably causes enormous ground vibrations, which, in turn, can affect the stability of the slopes comprising the various boundaries of the open pit mine. In addition, the method also has the problem of lowering the blast efficiency compared to other methods such as bench blasting methods or ones with more than two free faces. In this respect, a project was launched to develop a new blasting method that is suitable for controling the ground vibration and enhancing the blast efficiency. As a part of the project, authors investigated the current blasting method as well as the overall pit developing process in the mine, and established some important guidelines that should be observed during the whole development process. This paper presents the details of the typical blasting pattern and the pit developing method in the mine, and suggests the guidelines determined from the results of the observations.

This research attempts to investigate the geographical approaches on healing, which have been neglected in geography relatively, comprehensively and to examine the meaning of healing in daily life from the viewpoint of the managers of psychological counselling caf$\acute{e}$s. According to the results of this research, exposed healing spaces such as mental clinics or counselling centers are regarded as cultural stigmatic spaces; besides, psychological counselling caf$\acute{e}$s decrease psychological distance or resistance and people calling for healing can access these healing spaces easily. Second, healing spaces from a perspective of modern people mean geographical boundaries as refuges for a brief time; accordingly, the users' activities in psychological counselling caf$\acute{e}$s as instant or unexpected healing spaces in daily life are interpreted as special experiences without any emotional burdens. And these psychological counselling caf$\acute{e}$s are regarded as the spaces where can experience healing repeatedly and continuously. Third, psychological counselling caf$\acute{e}$s were changed into general caf$\acute{e}$s as open spaces; therefore, they can penetrate deeper into daily life rather than others.

We demonstrate here that an improvement in precursor film density (green density) leads to a great enhancement in the photovoltaic performance of CuInSe2 (CISe) thin film solar cells fabricated with Cu-In nanoparticle precursor films via chemical solution deposition. A cold-isostatic pressing (CIP) technique was applied to uniformly compress the precursor film over the entire surface (measuring 3~4 cm2) and was found to increase its relative density (particle packing density) by ca. 20%, which resulted in an appreciable improvement in the microstructural features of the sintered CISe film in terms of lower porosity, reduced grain boundaries, and a more uniform surface morphology. The low-bandgap (Eg=1.0 eV) CISe PV devices with the CIP-treated film exhibited greatly enhanced open-circuit voltage (VOC, from 0.265 V to 0.413 V) and fill factor (FF, from 0.34 to 0.55), as compared to the control devices. As a consequence, an almost 3-fold increase in the average power conversion efficiency, 3.0 to 8.2% (with the highest value of 9.02%), was realized without an anti-reflection coating. A diode analysis revealed that the enhanced VOC and FF were essentially attributed to the reduced reverse saturation current density (j0) and diode ideality factor (n). This is associated with the suppressed recombination, likely due to the reduction in recombination sites such as grain/air surfaces (pores), inter-granular interfaces, and defective CISe/CdS junctions in the CIP-treated device. From the temperature dependences of VOC, it was confirmed that the CIP-treated devices suffer less from interface recombination.

This study was performed to solve the quality problems of forging propeller shaft components in the marine diesel engines during the final cooling process and provide reasonable guidelines to increase the production of forging products. Residual hydrogen existing on the inside of forging products begins to diffuse and accumulates at the pores, micro-fissures, and grain boundaries as the temperature of forging products begins to decrease and reaches a critical temperature range, and finally transforming into internal defects. These defects were easily found near the surface of products after milling the surface of forging products. In this work, four types of forging products (shaft flange, shaft journal, thrust shaft, and propeller shaft) were chosen to evaluate the temperature history of products during the cooling process, employing non-linear numerical analyses with the ANSYS program. The times elapsed to reach 250 ℃ after cooling were approximately 9 ~ 23 hours for each forging product. These times can be used as cooling process guidelines on the quality and productivity of products after heat treatment.
