  • The various conditions of photographs, especially kinds of films, combinated filters and seasons are important factors for forestry purpose aerial photography. In this paper the variations of tones were compared between color and color infrared, panchromatic black and white and infrared black and white, and among false color photographic images created by using 3 kinds of filters when prints are made. Color infrared film was good for identifying tree species, for its spectral signatures had a greater range of tones and hues than color signatures. In that case taken in May were more effective than taken April. False color photographs were not so good as color photographs because they were mostly dark and indistinct. Infrared black and white film with medium red filter showed potential for separating broad-leaved forests from conifers. MSS composed photographs, when composed with proper bands and densities, were proved useful for distinguishing land use types but not applicable to more detailed practices such as forest type separation and tree species identification.

  • This study aims to share a methodology for locality reproduction by concretely explaining the theoretical model, procedure, and practice of constructing the Port of Busan Image Digital Archive, based on the photographic and postcard images of the Port of Busan, the representative place of Busan. Among the open-source record management programs, Omeka was chosen in implementing the digital archive because of its suitability for image exhibition. After establishing the principles for archive implementation in accordance with the purpose of the archive, a basic investigation was conducted for the record collection. With the consent of the individuals and institutions that possess the related records on the Port of Busan, such as the National Archives of Korea, the Busan Museum, and the City of Busan, original image artifacts were thus collected. The collected artifacts were then described using the Dublin Core metadata and categorized by time period. The Port of Busan was classified through four distinctive spatial characteristics (transportation, historic, industrial, and living spaces). A total of 11 themes for the exhibition was then suggested. The Busan-Shimonoseki Ferry Boat was chosen as an example exhibition of transportation space.

  • Purpose: Photogrammetry has been introduced as an alternative to direct measurement to obtain facial distances for a variety of anthropometric applications. The aim of this study is to establish morphological and functional value of an eye in Korean youths using specially designed computer software with digital photographic images. Methods: Authors measured anthropometry of an eye in Korean youths 1,449 individuals(622 males, 827 females) and analyzed stastically them. Results: The mean measurements are as follows. The diameter of cornea was $11.6{\pm}0.9mm$ in males and $11.3{\pm}0.9mm$ in females. The vertical dimension of palpebral fissure was $7.4{\pm}1.7mm$ in males and $8.2{\pm}1.6mm$ in females. The intercanthal width was $35.8{\pm}3.2mm$ in males and $34.4{\pm}2.9mm$ in females. The biocular width was $90.4{\pm}5.7mm$ in males and $87.4{\pm}5.3mm$ in females. The endocantion-superior margin of palpebral fissure distance was $12.7{\pm}1.4mm$ in males and $11.6{\pm}1.4mm$ in females. The horizontal dimension of palpebral fissure was $28.5{\pm}2.2mm$ in males and $27.4{\pm}1.9mm$ in females. The slant of palpebral fissure was $10.7{\pm}2.6^{\circ}$ in males and $11.3{\pm}3.0^{\circ}$ in females. The height of upper eyelid was $10.6{\pm}2.3mm$ in males and $10.7{\pm}2.3mm$ in females. The width of double fold was $2.0{\pm}0.7mm$ in males and $1.9{\pm}0.6mm$ in females. A double fold was seen in 21.9% of males and 44.9% of females. The most frequent shape of the double fold was type IV. The most common type of epicanthal fold was type III in both males and females. Conclusion: Photogrammetic measurement of large population using specially designed software could offer reliable data and these data could be useful reference for preoperative consultation, surgical planning and anthropometic study of eye.

  • Photographic images of the Samseong-version (三省本: Korea's Treasure No. 758-1) and the Gongin-version (空印本: Korea's Treasure No. 758-2) of Nammyeongcheon Hwasangsong Jeungdoga (南明泉和尙頌證道歌: Nanmingquan Song Zhengdaoge) were compared and analyzed to investigate the differences between the two versions. According to a report in 2012 at the time of the designation of the Gongin-version as Korea's treasure, both versions were printed from the same woodblocks. The Gongin-version is presumed to be a later print than the Samseong-version. The two versions are very similar in format and shape of border lines and characters. It is difficult to determine the differences with the naked eye, even for experts. In this study, based on the printing characteristics observed from each version through image analysis, useful evidence to determine whether it was printed using the same or different woodblocks and the order of printing was collected. As a result of careful image comparison and analysis, we concluded that the Samseong- and the Gongin-version were printed from different woodblocks, or possibly different typesetting. It was difficult to agree with the content of the report that the Gongin-version was a later print than the Samseong-version. In addition, it was noted that the Gongin-version print has characteristics quite different from the typical characteristics of woodblock printing seen in the Samseong-version. Additional investigations and follow-up studies on the printing technology used for Gongin-version print and the timing of printing are recommended.

  • Through the development of construction technology, various construction projects such as redevelopment projects, undergrounding of roads, expansion of subways, and metro railways are being carried out. However, this has led to an increase in the number of construction projects in existing urban centers and neighborhoods, resulting in an increase in the number of damages and disputes between neighboring buildings and residents, as well as an increase in safety accidents due to the aging of existing buildings. In this study, digital data was applied to a graphics program to objectify the progress of cracks by comparing the creation of cracks and the increase in length and width through photographic images and presenting the degree of cracks numerically. Through the application of the program, the error caused by the subjective judgment of crack change, which was mentioned as a shortcoming of the existing field survey, was solved. It is expected that the program can be used universally in the building diagnosis process by improving its reliability if supplemented and improved in the process of use. As a follow-up study, it is necessary to apply the extraction algorithm of the digital graphic data program to calculate the length and width of the crack by itself without human intervention in the preprocessing work and to check the overall change of the building.

  • The experimental studies were performed to observe the characteristics of the myelinated nerve fibers of the tradiaphragmatic branches of phrenic nerves in dog In the work to be reported five mixed breed Korean dog were used, they were one year old and he body eights were about 12 Kgm. in average with healthy conditions. The specimens (nerve) were taken at the point of 1.5 cm posterior part from the left and right phrenic nerves entrance to the diaphragm, and the dorso-lateral and dorso-medial branches of phrenic nerves vere also, taken at the point of 0.5 cm distal part from their branching portion. The specimens were fixed for 24 hrs. in Flemming's solution, and embedded in paraffin. The paraffin section. were cut at 6 microns and stained with Walter's modification of Weigert-pal method for the myelinated fibers. Microphotographs were taken and enlarged into 750 times of the actual size, and the diameter of the photographic images of the myelinated fibers were measured by the scale on the transparent Percepex Plate. The following conclusions were made: 1. The percentage of distribution of the several intradiaphragmatic branches of phrenic nerves were as follows. Ventral branches were 34.97%, lateral branches were 37.90%, dorsal branches were 27.13%, and the dorsal branches were branched again into dorso-lateral branches(54.22%) and dorso-medial branches (45. 78%). 2. The mean value and S.D. of the total numbers of the myelinated nerve fibers at the left ventral branches were $490.80{\pm}12$, and at the right ventral branches were $486.6{\pm}13$. Total average cross sectional area on the left ventral branches were 38,000. $6{\pm}136{\mu}^2$, and the right ventral branches were $37,150.2{\pm}1.782{\mu}^2$. 3. The mean value and S.D. of the total numbers of the myelinated nerve fibers at the left lateral branches were $533.8{\pm}8$, and at the right lateral branches were $525.6{\pm}7$. Total average cross sectional area of the left lateral branches were $41,582{\pm}1,170{\mu}^2$, and the right lateral branches were $40,454.8{\pm}812{\mu}^2$. 4. The mean value and S.D. of the total numbers of the myelinated nerve fibers at the left dorsal branches were $378.2{\pm}14$, and at the right dorsal branches were $380.2{\pm}8$. Total average cross sectional area of the left dorsal branches were $27,771{\pm}1,256{\mu}^2$, and the right dorsal branches were $27,507.2{\pm}645{\mu}^2$. 5. The mean value and S.D. of the total numbers of the myelinated fibers at the left dorso-lateral branches were $205.4{\pm}15$, and at the right dorso-lateral branches were $210.6{\pm}17$. Total average cross sectional area of the left dorso lateral branches were $15,354. 8{\pm}1,519{\mu}^2$, and the right dorsal branches were $15,887{\pm}1,297{\mu}^2$. 6. The mean value and S.D. of the total numbers of the myelinated nerve fibers at the left dorso-medial branches were $175{\pm}14$, and at the right dorso-medial branches were $176.2{\pm}17$. Total average cross sectional area of the left dorso-medial branches were $13,037.4{\pm}944{\mu}^2$, and at the right dorso-medial branches were, $13,103{\pm}1,373{\mu}^2$. 7. The highest frequent distribution of the intradiaphragmatic branches of phrenic nerves were found in the $10-12{\mu}^2$ groups, and they were almost 30% of the total groups. 8. The largest fibers diameter were in the $14-16{\mu}^2$ groups, and these were shown the lowest frequent distribution. 9. The largest cross sectional area of the intradiaphragmatic branches of phrenic nerves were found in the $10-12{\mu}^2$ groups. 10. All of the intradiaphragmatic branches of phrenic nerves were unimodal which has a peak in the $10-12{\mu}^2$ groups.

  • In this study, certain quality characteristics of kimbugak samples prepared with 2 different puffing methods, microwave oven and frying, and containing different levels of sea tangle powder(0, 2, 4, and 6%), were examined according to mineral content, moisture content, color values, photographic images, hardness and sensory evaluations. The mineral contents of Porphyra yezoensis were: K, 2,612.400 mg; Ca, 116.970 mg; Na, 486.099 mg; Mg, 297.800 mg; Fe, 9.636 mg; Mn, 1.614 mg; and Cu, 0.973 mg. And those of the sea tangle powder were: K, 5,115.000 mg; Na, 1,848.931 mg; Ca, 763.030 mg; Mg, 525.700 mg; Fe, 15.125 mg; Zn, 4.639 mg; and Mn, 0.146 mg. Moisture content was not significantly different among the samples of kimbugak puffed by the microwave oven and frying. For the color of the kimbugak made with the microwave oven or frying, L values decreased as the level of sea tangle powder increased. Color a and b values were lowest in the control group. The color values(L, a, and b) of the kimbugak puffed by frying were higher than those made using the microwave oven. The hardness of the kimbugak samples puffed using the microwave oven were not significantly different according to levels of sea tangle powder, and in the kimbugak puffed by frying, the lowest hardness was in the sample with 6% sea tangle. In sensory evaluations, color and crispness were not significantly different among the samples. The flavor scores of the 4% and 6% samples puffed by frying were higher than those of the kimbugak samples puffed using the microwave oven. The overall acceptability of the kimbugak puffed by frying and containing 6% sea tangle powder was the highest. In conclusion, 4 and 6% sea tangle powder would be considered optimum amounts for kimbugak puffed by frying.

  • This paper is a study of the changing nature of software for virtual Cyborg self and the virtual body that occur in the game from a philosophical point of view. Looking broadly, the cyborg concept refers to the combination of man and machine. Specifically, there is a hardware cyborg organism to combine human and restoration of machine In addition, there is software cyborg by electronic the human brain of converting a virtual body. Virtual games are cases software-Cyborg applied. In the game , There seems to have characteristics of virtual body and ego that different from general cyborg meaning. To analyze the features, I applied the concept of software-cyborg of Hans morabek and the multiple selves in cyberspace properties of Kim Sun-Hee. generally, software cyborg cloning the brain type tended to invalidate the body due to the nature of the virtual world. But If you look at third-person's view and the game character that made from real actors, it is pursuing the realism of photographic images and it stressed the need for a virtual body in order to maintain the psychological identity of the player. And, The game player crosses the eight characters to choose while completing the mission. This is a big role in the reality ego leads to the desired final ending with the selection and experience to be experienced as self-replication to multiple. These cyber multi-ego looks for an active and positive features compared to the multi-ego in the real world and highlights the advantages of the software cyborg. Game The characteristics of the final result varies depending on the selection of the player. The life and death of a friend is determined by the relationship between the characters friendship. In this case, the virtual self is empirically through trial and error, moral, and try to select the desired setting the standard for intuitive and self own choice. Also It can be fused to the knowledge of multiple selves as one step is formed by a high spiritual introspection. This process is a positive interpretation of the world and their own forms of mental reflection through self-overcoming human, Nietzsche is said that the process is Wibeomenswi.
