Not only in Korea but throughout the entire world millions of people are in contact with images. Images have become a medium through which to transmit anything from simple visualizations of moving images to knowledge and information. The age of the internet has arisen thanks to scientific development, and the internet generation's acquisition of information is continuously becoming faster. The spectators, ufo must choose amongst the excessive amount of available information, are changing along with it just as quickly. The method of visual transmission has changed to match the demands of the fast-changing pace of the new generation. In order to receive an instantaneous selection amongst much information, the primary requisite is attracting one's attention, and then presenting a corresponding feeling of satisfaction. The early stages of film arose from the desire to capture one's actual situation as it realty is. Unsatisfied with the still picture, people developed the motion picture. Research has succeeded in reproducing 3-dimensional images more realistic than the actual image we perceive as a result of the difference in visual perspective of both eyes and their response to rays of light From color film to 3-dimensional pictures, people enjoy the magnificent results of this. All fields within the category of film are continuously studying the human desire to pursue their visual side, namely the pursuit of visual images with a maximum sense of reality. The images that millions of people around the world see now are flat. The screen's depth and optical illusions effectively give a sense of reality while conveying information. However, although the flat screen is able to create a sense of depth using the different visual perspective of each eye for the realization of a cubic effect, there are limitations. Entering the 21s1 century, there is a quickly-arising branch within the field of image media which seeks to overcome these limitations Although 3-dimensional images began in films, entering the latter half of the 20th century, due to development of 3-dimensional images using the mediums of the animation field, cellular phones, advertisement screens, television etc., without restriction is designated as 'image.'. With research having started around 1900 and continuing for over 100 years, we are now able to witness the popularization of 3-dimensional films happening before our very eyes. Within our own country, we can frequently see them at amusement parks and museums. In the future, through the popularization of HDTV etc., there is a good outlook for practical use of 3-dimensional images in televisions with advanced picture qualify as well as in other areas. Together with the international current, research on 3-dimensional films has been activated in Korea and is rising as a main current in the film industry. Within this context, the contents and understanding of 3-dimensional images must keep in step with the pace of technical advancements. In order to accelerate of development of film contents to keep in pace with technical developments, this dissertation presents the techniques and technical aspects of future developments, and shows the need to prepare in advance to make the field grow- and thereby avoid having a lack of experts and being conquered by other nations in the field - rather than only advancing the technical aspects and importing the contents. This dissertation aims to stimulate interest and continual research by progressive-thinking people related to the film industry. Part II looks into the definition and types of 3-dimensional motion pictures, the terminology, the fundamentals of image formation, current market fluctuations, and looks into 3-dimensional techniques which can be borrowed and introduced in 3-dimensional animations. Part III concerns 3-dimensional animated films. It analyzes 3-dimensional production techniques while using the introduction of specific animation techniques in the 2004 production Lee Sun Shin and Nelson - Naval Heroes 3-dimensional animation produced in 2004 by Clay & Puppet Stop-Motion Animation & Computer Graphic. Original Korean title: 해전영웅 이순신과 넬슨. as an example, and it also looks into how current film techniques used in animations can be applied in 3-dimensional films. Additionally, the actual stages of the various fields of 3-dimensional animations are presented. Given the current direction and advancement of 3-dimensional films making use of animations and the possible realization of this field, the author plans to weigh the development of this yet unexploited new market Not looking at the current progress of the field, but rather the direction of the hypothetical types of animation techniques, the author predicts the marketability and possibility of development of each area.

By treating skin diseases with Hyungsang medicine and reviewing the clinical cases of them through classifying skin diseases into general care and into Hyungsang medical care, the writer came to the conclusion as followings. The skin is a house of Kyungnak, and it' s a place which Ki comes in and out, which human body controls conditions of his physiological function and which doctors can make a diagnosis from seeing it. The skin is subject to lung and large intestine in the point of organ, but in the point of movement, to spleen and stomach. Skin diseases come from unbalance of Ki and Hyul, mostly from fever in blood and also from Dam, Wind, Dampness and Dryness because of including fire. Generally skin diseases are treated according to classifying into distinctive symptoms, region, cause or time being occurred, and concomitant symptoms. After being divided into man and woman, age and youth, fatness and leanness, Jung Ki Shin Hyul type, visceral figures, Yukkyung shapes on Hyungsang medicine method, the remedy of skin diseases which is combined common meditation with Hyungsang medical method is efficacious. In distinguishing into man and woman, age and youth, man gets sick mainly by drinking liquor and exhausting Jung, woman is taken ill generally by indigestion and Damwha, especially by drinking liquor. Young child gets ill mostly from inherent weakness, but in many cases he is occurred by disturbed digestion, so he must be taken care of ingesting food. The aged becomes ill from weakening, so he must be treated according to reasons of diseases. To fatness and leanness, skin diseases are showed symptoms by weakened Yang, insufficient Yin or excess fever on the theory of upper and lower parts, by unbalance of Ki and Hyul on the theory of left and right, by Dryness and Dampness on the theory of front and rear and by insufficiency of vitality and combined fever on the theory of inside and outside. Therefore doctors must cure the symptoms according to the theory of upper and lower, left and right, front and rear and inside and outside. In type of Jung Ki Shin Hyul, the balances between Jung-Hyul and Shin-Ki are important points. Concretely Jung type comes to easily shortage of Jung or gathering abnormally Dampness and Dam, Ki type is easy to make a mass with Ki or to be deficient of Ki, Shin type comes to press seven emotions togather or to be insufficient of Yin and fever inside, and Hyul type is inclined to be deficient of Hyul and to become feverish or to be deficient of Ki. Therefore on the ground of the above reasons skin diseases come into existence. Inclusively in Jung-Hyul type , Ki must be moved on the base of full Jung-Hyul, so Wukmijiwhangtang or Samultang is prescribed basically. In Shin-Ki type , Jung-Hyul is saved on the base of moving Ki, so Hyangsosan or Yijintang is the proper prescription. Considering the visceral figures, doctors judge for diagnosis and remedy by putting together the elements, that is, great and small sizes of a set of features (eye, ear, mouth, nose), color and temper. The yukkyung types are classified according to many or few of Ki-Hyul, and then skin diseases appear by being inclined toward one side between Ki and hyul, or among the six atmospheric elements(wind, cold, heat, dampness, dryness, and fire). Especially because Yangmyung type is full of much Ki and Hyul, and also has much fever in stomach, he gets skin symptoms frequently. So his prescription is based on taking off fever in stomach, and also he must be careful about regimen certainly.

This study was performed to investigate the feeding effects of different additives on the growth performance and carcass characteristics of Holstein steers. Twenty-four Holstein steers, five months of age and 176.6 kg, were randomly allocated to three experimental groups of eight animals each for an 18-month feeding trial. The groups were control (not additive), T1 (fed zinc, vitamin C, and sulfur), and T2 (fed choline and lysine). The average daily gain was no different between the treatment groups during the growing to early fattening period, but it was significantly higher in the T1 group than the T2 group in the late fattening period (p<0.05). The final BW of the T1 group was relatively high in relation to the other groups, but was not significantly different. The additives had no effects on DMI during the experimental period; however, the feed conversion ratio of the T1 group in the late fattening period was significantly lower than that of the T2 group (p<0.05). The results of yield traits, carcass weight, and yield index were similar between groups, but back fat thickness and rib eye area were relatively lower in the T2 group than in the other groups. In terms of quality traits, meat color, texture, and maturity were not significantly different between the three groups. However, marbling score and appearance rate of high quality grade ($1^{++}$, $1^+$, and 1) were higher in the T1 group compared with the T2 group. Thus, the present results suggest that vitamin C, zinc, and sulfur supplementation may improve the growth performance and carcass characteristics of Holstein steers.

This study tested the association between genetic polymorphisms of the isocitrate dehydrogenase 3, beta subunit (IDH3B) gene and economic traits in an F₂ crossbred population of Landrace × Jeju (South Korea) Black pigs. A 304-bp insertion/deletion mutation in promoter region was screened for determining genotypes of the IDH3B gene in a total of 1,105 F₂ pigs. Three genotypes (AA, AB, and BB) were identified in the founder, F₁, and F₂ populations. Association analysis showed significant differences in carcass weights (CW), backfat thicknesses in three positions of the body (4^th-5^th ribs, BF5; 11^th-12^th ribs, BF12; 13^th rib-1^st lumbar, BFL), and carcass lengths (CL) (p<0.05), but not in meat color (MC), eye muscle area (EMA), or marbling scores (MARB) (p>0.05). The F₂ IDH3B BB homozygotes showed heavier CW (80.790±0.725 kg) and shorter CL (101.875±0.336 cm) than the other genotypes (p<0.05). In addition, the BF levels between the 4^th - 5^th and 11^th - 12^th vertebrae were thicker in the carcasses of pigs with the IDH3B BB genotype than with the other genotypes (p<0.05). These results suggested that genetic variations in the IDH3B gene may serve as molecular genetic markers for improving the Landrace × Jeju Black pig crossbreeding systems.

The chicken eye can discriminate light color, and different light wavelengths may affect reproduction ability. This study was carried out to identify effect of monochromatic light using light emitting diode (LED) in laying hens. Chickens were exposed to white light (WL), blue light (BL), yellow light (YL), green light (GL) and red light (RL) made by using LED as well as incandescent light (IL) (control). All light sources were equalized to a light intensity of 20 lux. The results indicated that the age of first egg laying and 50 % egg laying in laying hens treated under RL is significantly younger than under other lights (P<0.05). And the ovary weight of laying hens reared under RL is significantly heavier than under other at from 16 to 20 wks (P<0.05). The largest number of eggs production was produced in a group with treated with RL by 59 wks of age compared with any other group. The egg weight of YL was greater than other treatment groups from 26 to 45 wks (P<0.05). The egg shell from hens treated with RL was the strongest and thickest at 20 wk (P<0.05). These results suggest that the egg quality of laying hens reared in different spectrum of LED can be different and RL may enhance the laying performance.

Analyses were conducted to estimate the effect of backfat thickness (BFT) on carcass grade factors and carcass price in Hanwoo cows and steers. Data on grade factors and prices were collected from 69,159 Hanwoo carcasses (n = 13,376 cows, n = 55,783 steers) abtained at the Nonghyup Seoul slaughter house in 2009. Carcass BFTs were divided into nine categories from ${\leq}$ 3 mm to ${\qeq}$ 25 mm. The average BFTs were 11.93 mm in cows and 12.57 mm in steers. An increase in the BFT resulted in an increase in carcass weight, loin-eye area, skeletal maturity, fat color, but decreases in the yield index and yield grade (from grade A to C) in cows and steers. Carcass unit price (Won/kg) improved if the carcass was sold with a BFT of 13-15 mm in cows and 10-12 mm in steers. Marbling score and quality grade increased significantly to 21 mm BFT but decreased from a BFT of 22 mm in cows and steers. BFT was significantly correlated with yield index (cow, r = $-0.97^{**}$; steer, r = $-0.96^{**}$), marbling score (cow, r = $0.20^{**}$; steer, r = $0.14^{**}$), and carcass price (cow, r = $0.03^{**}$; steer, r = $-0.11^{**}$). These results could be used as a fundamental dataset for further research to increase the productivity of Hanwoo carcasses.

This study was carried out investigate the effects of the period of dietary supplementation and the level of fermented mineral feed on daily body weight gain and carcass characteristics of Hanwoo steer. The dietary treatments were compared during two supplementation periods (T1:Feeding Hanwoo steers from 18 months to 25 months, T2: feeding Hanwoo steers from 7 months to 25 months), and the diets tested were of four types (0%: normal concentrate as a basal diet, 1%: 1% addition of fermented mineral feed, 2%: 2% addition of fermented mineral feed, and 3%: 3% addition of fermented mineral feed). A Total of 35 Hanwoo steers were allocated into 7 feeding groups. The daily gain of the 0% fermented mineral feed group was lower (0.64 kg) than that of the other groups (1%: 1.08 kg, 2%: 0.90 kg, 3% treatment: 0.75 kg) for the T1 period, and for the T2 period the order was 1% (0.98 kg) > 0% (0.75 kg) > 1% (0.89 kg). The amount of back fat in decreasing order was as follows: 0% (12.0) > 1% (10.8) > 2% (10.2) > 3% fermented mineral feed (7.8 mm) for the T1 period, and for the T2 period the order was C (16 mm) > T1 (13.8 mm) > T3 treatment (12.6 mm). Eye muscle area increased with increased fermented mineral feed levels. The marbling score of the T1 groups was highest with 3% fermented mineral feed (4.2), and of the T2 groups, the highest score was seen with 1% fermented mineral feed (5.6). Meat color and meat maturity were not different among all groups. The grade of meat quantity and meat quality of both the T1 and T2 groups were highest with the addition of 3% fermented mineral feed. The daily income ranged from 2,062 won to 5,265 won in the T1 groups, which were ordered as follows: 1% > 2% > 3% > 0% fermented mineral feed, and of the T2 groups, the 1% group was highest at 6,098 Won, while the 3% group was lowest at 4,590 Won.

This study was conducted to investigate the nutritional composition and meat quality properties of Hanwoo steer beef by different cut. Ten cuts [Abjin (short plate), Bosup (top sirloin), Cheggt (striploin), Dngsim (loin), Guri (chuck tender), Hongduke (eye of round), Moksim (chuck roll), Sulgit (bottom round), Udoon (top round), Yanaji (brisket)] prepared from 10 Hanwoo steers (28-30 months old) were used for this experiment. The range of pH was 5.46-5.64. In the chemical analysis, Hongduke contained highest protein contents (21.15%) and Dngsim had lowest protein contents (16.94%) (p<0.05). Fat contents were higher in Dngsim whereas those of Guri, Hongduke and Udoon were significantly lower when compared to the other cuts (p<0.05). There were not significantly different in meat color (L, a and b values) properties only except that L values were significantly higher in Dngsim among 10 cuts (p<0.05). Cooking loss (%) was higher in Guri, Hongduke, Udoon and Yangji whereas it was significantly love. in Cheggt (p<0.05). Warner-Bratzler shear force (WBS) was significantly higher in Abjin $(6.24inch^2/kg)$, whereas Dngsim $(3.45inch^2/kg)$ and Cheggt $(3.50inch^2/kg)$ were significantly lower than the other cuts (p<0.05). There was no significant difference in water-holding capacity (WHC) among 10 cuts (p>0.05). Total amino acid contents were significantly higher in Hongduke (p<0.05). Hongduke was highest in most kinds of amino acids, however, Udoon had the highest methionine and histidine contents among 10 cuts (p<0.05). Glutamate contents were high in all cuts and followed by aspartate, leucine and lysin. With regard to mineral contents, Ca was ranged from 47.63-70.69 mg/kg and Fe was ranged from 15.09-26.68 mg/kg in 10 cuts. Zn was highly contained in Guri (50.56 mg/kg) when compared to the other cuts (p<0.05).
