Currently, a cartoon is generally used for a term implying a short cut strip based on satire and humor in Korea. Today, the way of expressing a cartoon includes the active utilization of expressive ways through digital medium as well as traditional methods, and the introduction of oriental feelings or an engraving which is a technique used in fine art. Also, there is a three-dimensional cartoon utilizing objets such as cup and handbag. This study was conducted on assumption that the area of a cartoon may be extendable with a three-dimensional technique added with a tactual sense. Also, this thesis is aimed to identify the possibilities of the industrialization of cartoon contents and of becoming an edutainment (education + entertainment) through a new cartoon technique, and to prepare the basis for scientific research necessary for extending the domain of a cartoon.

We proposed new light guide panel (LGP) fabrication method exploiting laser-processed inner scatterers and surface pattern. The proposed method has achieved LGP performance improvement in both brightness and uniformity. The inner scatterers and surface pattern of grid type were fabricated with a 2nd harmonic Nd:YAG pulse laser engraving system and a $CO_2$ laser scanning system, respectively. In the implementation of LGP, inner scatterers was arranged in accordance with linear or curved pattern with changing density and surface pattern was engraved on the surface of an inner-scatterers embedded LGP. The increase of scatterers' density and the use of surface patterns in both linear and curved pattern provided high luminance and uniformity enhancement. While thecurved pattern incorporated with increased scatterers' density and surface patterns yielded brightness improvement with preserving good uniformity, the linear pattern showed highly localized brightness near the light entrance of the LGP. We can also observe that the uniformity was mainly determined by pattern of inner scatterers, and the brightness was improved by the higher density and the utilization of surface patterns. From the results, the use of laser-processed inner and surface patterns can be a potential alternative for efficient and simple LGP fabrication method.

This study aims to analyze how the color of Korean traditional architecture affects its plasticity. The researcher took (our distant and near photographs of each representative building of each use, measured the colors, and analyzed these using the color perception theory. The results are summarized as follows: 1. When perceiving the entire plasticity of a building, the color of Korean traditional architecture reduces the heavy feeling that may be brought about by the roof's weight, but stresses the solidity of the pillars. This color perception effect displays the visual stability and balanced plastic beauty of the building's facade. 2. When looking at a building up close, the building's color emphasizes the solidity of the major materials used to construct it through a contrast effect, and highlights the characteristics of each building, such as the dignity of its seal engraving, its magnificence, its simplicity, etc. 3. The color of Korean traditional architecture is a major factor that expresses plastic language as it displays topographical level differences and intercepts or opens view through the artificial division of space, etc., according to the building's use.

The stiffness of multi-articulated industrial robots is very weak, because their structure is an articulated type with some links and joints. Thus it is known that cutting processes for metals are not accepted in machine shop well, but they have a lot of merits for cutting processes, for example, drilling, tapping, and engraving etc, because of the characteristics of their high degree of freedom. The temptation of cutting aluminium was carried out to investigate the feasibility and the limitations or constraints for cutting metals on them. First the mode shapes of 6 degree of freedom welding robot were taken and analysed, and next the cutting processes were practically carried out on it. The results of study were found out to show the feasibility of cutting processes at drilling under 6mm of tool diameter, as well as to have some limitations and constraints, for examples, feed rate, depth of cut and cutting force etc.

The general way to process the surface by means of the laser was heat treatment for strengthening the surface hardness. They have used the laser for changing the property of the surface, especially for metal. Generally, it is recent increasing tendency to use the thin plate panel for making things smaller and lightweight. However, thin plate should be strengthened or let the thin plate panel have moment of inertia by means of engraving the groove or wave on them for lightweight and strengthening. Therefore it is expected that the thin plate panel can be harder and more stable through processing the metal surface by laser beam irradiation and the hardness of thin plate possibly can be also changed how many parts of them are harden. Through this research, it can be grasped how the hardness and mechanical characteristic changes according to width and depth of groove by laser affect the max stress by the ratio of $A_H/A_T$ (hardening area/total area) and characteristic of displacement and structural characteristic for making the thin plate harder by the strengthening metal surface of thin plate by laser through the experiment and analysis of FEA can be presented.

We report on the fabrication and characterization of self- and artificially-controlled ZnO nanostructures have been investigated to establish nanostructure blocks for ZnO-based nanoscale device application. Systematic realization of self- and artificially-controlled ZnO nanostructures on $SiO_2/Si$ substrates was proposed and successfully demonstrated utilizing metalorganic chemical vapor deposition (MOCVD) in addition with a focused ion beam (FIB) technique. Widely well-aligned two-dimensional ZnO nanodot arrays ($4{\sim}10^4$ nanodots of 130-nm diameter and 9-nm height over $150{\sim}150{\mu}m^2$ with a period of 750 nm) have been realized by MOCVD on $SiO_2/Si$ substrates patterned by FIB. A low-magnification FIB nanopatterning mode allowed the periodical nanopatterning of the substrates over a large area in a short processing time. Ga atoms incorporated into the surface areas of FIB-patterned nanoholes during FIB engraving were found to play an important role in the artificial control of ZnO, resulting in the production of ZnO nanodot arrays on the FIB-nanopatterned areas. The nanodots evolved into dot clusters and rods with increasing MOCVD growth time.

Recently, the engraving of letters or a pattern on a product surface has received more attention especially in trying to satisfy the customer requirements. Half-piecing is a protrusion forming process that pierces only 40~50% of the material thickness. In the current study, the half-piercing technique for making clear letters by protruding sheet material was selected and studied. The influence of clearance and penetration depth was investigated by measuring the camber and extruded length of a protrusion after experiments. In addition, a numerical analysis was performed for the same working conditions and compared with experimental results. It is shown that, as the clearance increases, the camber of a protrusion increases rapidly and the extruded length decreases slightly. The deformation pattern around the cutting edge during half-piercing changes from an extrusion mode to a shearing mode as the clearance changes from minus to plus values. It is also confirmed that the experimental results show a good agreement with the numerical analyses.

The Meridian and Collateral Diagram is one of the most important 圖像s of Traditional Korean Medicine. A 圖像 is a picture made on a two-dimensional surface using lines and colors to portray an object or an image. Meridian and Collateral diagram is a 圖像 of the human body with indications of acupoints and meridian passageways and have different names such as 經穴圖, 輸穴圖, 鍼灸圖, 明堂圖, 銅人圖, in accordance with its classification. The documental basis of the Meridian and Collateral Diagram is the Internal Classic and the very first Meridian and Collateral Diagram confirmed through textual evidence can be found in 葛洪's "抱朴子 雜應". The Korean 동인도 in existence today, called '銅人明堂之圖', exists in two versions; a hand-copied version and a wooden engraving block version. It displays all the locations of the acupoints located on the anterior side of the human body, labels the names of the acupoints, and specifically distinguishes 起始穴 and 終止穴 of the eight meridian vessels.

The purpose of this study is to examine the realities of the chaotic use of terms, 'tattoo' and 'moonsin', through the empirical field researches. This paper will research the differences in the origins and the etymological meanings of 'tattoo' and 'moonsin' through examining related literatures. Clarifying the term definitions on 'tatto' and 'moonsin', this research is to help fashion consumers to use these terms discretely. In order to figure out consumers' perceptive attitude, this study has performed the questionnaire inquiry and has reached the result by analyzing the level of frequency of using the two terms. 1. The result of the term-preference inquiry tells that consumers prefer 'tattoo' to 'moosin'. However, the inquiry shows considerable number of them use the two terms indiscretely. 2. The study on the perceptions from the two terms shows: the term 'tattoo' is often related to positive images-fashionable, charming, and sexy, and the term 'moonsin' to negative ones-violent, anti-social, and demonic. 3. Both 'tattoo' and 'moonsin' shares the similarity in terms of engraving patterns on skin and coloring them. 4. 'Tattoo' is originally derived from the Polynesian word 'tatau', which means 'artistic'. 'Tatau' is a kind of ethnic art practiced on Polynesian people's skin. The design patterns and practicing techniques are very similar to those on the Polynesian earthware called 'Lapita'.
