(K)Hanbok, which is Korea's traditional clothing, differs from the Chinese Hanfu or Japanese Kimono. This study aims to understand the fundamental differences between (K)Hanbok and Hanfu. The Goryeo Dynasty (K)Hanbok, which was particularly popular in China, was established because the Ming Dynasty Hanfu and Chinese fashion were considerably influenced by the 'Koryo Yang'. Firstly, while (K)Hanbok is bulky, Hanfu of the Han Dynasty is characterized by forming a slim silhouette. Due to the climate of the Northern Hemisphere, (K)Hanbok shows a rich silhouette comprising multiple layers of inner pants and a pleated skirt over a voluminous underskirt. On the other hand, the Han's Hanfu creates a straight silhouette in the form of a wrap, revealing the contours of the body. The pleated skirt of the (K)Hanbok can use six to twelve width fabrics, depending on the social position; however, the Hanfu of the Han is a skirt without any pleats. Secondly, the clothing patterns, which have various shapes, are totally different in how they are made and sewn. The Korean (K)Hanbok is a two-piece separate, whereas the Chinese Hanfu style is a one-piece with a skirt. The short length of the (K)Hanbok jacket has a Sup which is cut and pasted allowing the front closure to overlap. Nevertheless, the Hanfu of the Han does not have this Sup because it is of a wrap-around, one-piece style and has an exceptionally large front, and wraps around at the waist which extends to the sides. Thirdly, the (K)Hanbok jacket has separate string Gorums for fastening, and an additional belt around the waist; however, in the case of Gorum, it is unnecessary for a wrapping style of Hanfu. Fourthly, Koreans as an agricultural horse-riding people, basically wore the trousers attached a comfortable gusset, while the Chinese Hanfu had no pants, but the Chinese wore Gaedanggo pants which exposed the hips, inevitably during the Warring States period.

As part of a study to analyze the excessive camber occurring in prestressed concrete railway bridges, this paper presents a calculation method and analysis results for the creep coefficient which defines the increase in camber of a concrete structure over time. Using the creep coefficient formula of the design code, the coefficient is obtained by applying the climatic conditions (relative humidity and temperature) of 12 regions in Korea. The effects of differences in climatic conditions by region and starting time of load on the creep coefficient are analyzed. In order to properly calculate the creep, most of which occurs in the early stages of loading, a detailed analysis is performed by applying a time step analysis method to consider varying climate conditions through loaded period. The creep coefficient obtained by applying the average climate conditions of the region is similar to the average of the creep coefficients obtained by time step analysis. Through time step analysis, it is shown that the offset and overlap effects of relative humidity and temperature on the creep coefficient and the climate effect at the time of initial loading can be appropriately represented.

This study looked at the sacrifice space building in the Changbai Mountain area to a specific era in terms of the cultural landscape. The scared of Changbai Mountain how changes in history came despite the regime and national change, interpretation of the reason was the scared maintained. The results of this study are as follows. First, Replacement of the regime in the Republic of China in the Qing period, ethnic diversity, underwent a cultural acceptance. So Changbai Mountain nature of sacrifice, the divine subject has formed the changes. Second, the Qing Royal sacrifice space Wangji Temple(望祭殿) have formed a unique cultural space and the sacrifice of authoritative content with only space. The Republic of China period, a new folk beliefs were born between the defense in the face of the Han Chinese migration and settlement process. Build Sacrifice space of Rulai Temple(如來寺) and Shanshenlaobatou Temple(山神老把頭廟). Third, the spatial relationship between the priest and the Changbai Mountain area Wangji Temple(望祭殿) is the power of space as vertical space. Rulai Temple(如來寺), Shanshenlaobatou Temple(山神老把頭廟) is located in the Changbai Mountain and horizontal space was obedient to the space. Fourth, the sacrifice ritual Wangji Temple(望祭殿) of the Qing Dynasty is the only ritual sacrifice of satisfaction. It is cut off depending on the abolition of imperial power. Currently, public ritual sacrifice is commonplace rituals and sacrifices of the Qing Dynasty is only formally underway. In conclusion, as it has been maintained for the sanctity historically Changbai Mountain. Changbai Mountain sacrifice space was changing through the acceptance of the replacement of the regime and culture of ethnic offerings from a single culture of the Qing Dynasty. Currently, to form a sacrifice space and culture overlap through a mutually acceptable.
In proceeding with orthodontic treatment, the prediction for the shape, growth rate and growth direction of mandible plays a major role to set up the treatment plan and determine its period and prognosis. Various approaches being made so far have shown that the linear and angular measurement using lateral cephalograms are relatively accurate to estimate them. This study was purposed to find the shape of mandible more clearly by preventing the overlap of the Condyle head area which appears in lateral cephalogram, and to estimate its growth rate by comparing the growth quantity and ratio via lateral area measurement. This experimental was performed against 40 patients total, of which Class I of 14, Class II of 9 and Class III of 17 consist. Wide open lateral cephalograms of 40 patients were taken over average period of 4 Year 3 Months, then the linear and angular measurements were carried out with 11 itemized lists. Autocad Rl4 application program was utilized to draw their appearance, measure and compare their lateral area. As a result of study, conclusions were made as follows; 1. Mandibular body length (gonion-menton) tended to increase in order of CIII, CI and CII, and Mandibular body length of CIII group had a tendency to grow twice faster than that of CII group. 2. In lateral items such as Go-Me, A-Cd, B-Cp, E-F and G-H, CIII showed a significant increase on the year-average quantity and rate of the growth, and especially apparent difference was observed in CIII group rather than CII group. 3. For the 4 Year 3 Months period, the year-average growth quantity of lateral area of the mandible was $1.0cm^2$ for Class I, $0.8cm^2$ for Class II and $1.4cm^2$ for Class III, which corresponds to $11.9\%,\;11.8\%\;and\;20.3\%$ of growth ratio respectively. Thus, growth ratio almost 2 times more than other groups was observed in group CIII while growth ratio between group CI and CII has little difference. 4. Considering the results as above, it can be proposed that the difference in size of the mandible between groups is caused by the difference in the growth rate and growth quantity of the mandible, which generated in the middle of growth, rather than the difference in size of congenital Jaw-bone.
The bilateral sagittal split ramus osteotomy (BSSRO) is preferred method of surgical correction for mandibular prognathism, retrognathism and asymmetry. This technique performed from primarily an intraoral incision to avoid a scar. After forward movement of the distal segment of the mandible, healing of bone by primary or secondary intention is easily accomplished through large areas of cancellous bony overlap. When rigid fixation is used for the BSSRO, it is possible to open the mouth during the immediate post-operative period because it promotes the healing process. Although this surgical procedure has been well-documented, the incidence of postoperative trigeminal neurosensory disorder in the region of the inferior alveolar nerve and the mental nerve remains one of the major complication. However, evaluation of objective methods for sensory recovery patterns is insufficient although most patients find their sensory return. Neurometer electrodiagnostic device performs automated neuroselective sensory nerve conduction threshold evaluation by determining current perception threshold (CPT) measures. The purpose of this study was to evaluate the sensory recovery patterns of inferior alveolar and mental nerve over time. Nerve examination with a neurometer was performed in 30 patients undergoing the BSSRO at pre-operative, post-operative 1-, 2-, 4- week, and 2-, 3-, 4-, 5-, 6- month follow-up visits after the osteotomy to compare the differences of nerve injury and recovery patterns after the BSSRO with or without genioplasty and sensory recovery patterns associated with the kind of nerve fiber.

Frank Lloyd Wright(1867-1959) was regarded as the pioneer of the modern architecture in the beginning and transition period of 20th century. His works have the pure shape form which have the deep relationship with the organic architecture. Wright told himself that the Froebel System had an influence on his works a lot. This study have researched about the three dimensional application of the Froebel System in his works with assembling and disassembling. Also the two dimensional application in the diagonal and circular plans are the one of the subjects here. The following conclusions are reached. First, The similar of the Wright's works and the Froebel System was the application of the similar principles rather than the copy of the method, which are the accent of the center, the composition of the part and whole, the understanding of the composition principle through the unit system and the unfolding of the crystal by rotation. Even thought the Wright's works have the triangle, square, hexagonal shape, the way of the expansion from the centered space was same. Also the space formed by the division of the center space, unfolds making the part and whole by overlap and continuation. The 2nd Froebel make space decided by the Net and Crystal Lattices which have the crystal characteristics by the rotation. The new geometric architecture, pinwheel, was created by this method. The application of the Froebel in the Wright's works have the several sets which are the 3th, 4th, 5th, 6th Froebels, 2nd, 7th Froebels and the 3th, 5th, 9th Froebels. The geometrical analysis of the square shape and the diagonal shape of the Wright's works was possible. The unfolding of the centered space can be found in the Guggenheim Museum using the analysis of the circular geometric of the 9th Froebel. The above study proves that the Froebel was not a mere tool for the basic shape training but also the main body of Wright's works which consists of the organic idea and philosophy of the space.
To know the variation in the growth of the sea urchin, Pseudocentrotus depressus according to their localities, three different populations including the culture populations, the released populations, and the wild populations were investigated using the cluster analysis. For this purpose, pigment banding pattern on the genital plate was used as an age character. The population composed of the same year class was born between September 25th and October 5th every year. The population of 9 to 10 months old had no $r_1,\;whereas\;r_1$, was observed in the population of either 1 year and 10 or 11 months old, and both $r_1,\;and\;r_2$ in the population of either 2 year and 9 or 10 months old. Therefore, $r_1,\;and\;r_2$ radius were regarded as an annual ring. Growth in the culture populations was much better than that In either the released or the wild populations. However, when the cultured populations composed of 8 to 12 mm in test diameter was released to the shove near a culture farm, its growth appeared to be similar to that of the wild Populations. The wide distribution patterns of test diameter measured from the same year class of both the cultured and the wild populations were probably due to either long spawning period or growth differences between individuals. Except Yamaguchi and Cheju populations, the move closely located populations showed the more similar growth pattern. However, the growth of Cheju population appeared to be similar to that of Aba, Mogi, Toishi rather than Kasiwazima although Cheju Island was more closely located with Kasiwazima than other localities. In addition, the population of Yamaguchi, located at the highest latitute, revealed the similar growth pattern to that of Nomozaki, located at the lowest latitute.
X-ray Chest P-A is very important and basic diagnosis examination for pregnant women. For a pregnancy period pregnant women should be treated very carefully not to be exposed to any radiation which might cause harmful damage to women and babies as well. Lead apron is one of the effective methods to protect pregnant women from the X-ray radiation. However, it is difficult to obtain the accurate position of pregnant women during X-ray Chest P-A since conventional lead apron method forces pregnant women to hold the apron by themselves only to make pregnant women very uncomfortable and hard to maintain accurate position during radiation. As a consequence, it is common to get low quality images of X-ray Chest P-A due to the overlap of apex of lung and scapular. In order to fix this problem, we made new design lead apron that allowed pregnant women to be more comfortable to maintain accurate position during X-ray Chest P-A position. Finally, with this new design lead apron, it was possible to get the best optimized images of X-ray Chest P-A of pregnant women by minimizing overlapping apex of lung and scapular.
Korea's national income statistics have been compiled by the Bank of Korea since 1953. However, there is a break in the time series. The current time series (1970 onward) is based on the '1993 SNA (System of National Accounts)' suggested by the UN, and the previous time series (1953~1970) was based on the '1953 SNA'. The difference between the previous and current time series is 4.8% in 1970 when the two series overlap. The difference is even greater in terms of comparisons across industries. In addition, it has now become even more difficult to connect the current and the previous time series because, in 2009, the Bank of Korea introduced a chain weighted method for calculating the current time series (1970 onward). Under the chain weighted method, the time series underwent substantial modification; for instance, the economic growth rate during 1970~2005 is 0.9%p higher than the rate under the general method. This paper applies chain weighted values and the '1993 SNA' to the previous time series (1953~1970) by utilizing various national account manuals published by the UN and previous Korean input-output tables in order to calculate a long term time series from 1953 to 2010 based on the same criteria as the current time series (1970 onward). In the revised time series, it appears that 1953 GDP at current basic prices is 3.5% higher and the growth rate for the period of 1953~1970 is 1.5%p higher each year than under the previous time series. Under the revised time series the size of the Korean economy as of 2010 is 50-fold bigger than that of 1953. In terms of industries, manufacturing and SOC show significant expansion whereas the extent of that of the service industry is relatively small.
A statistical approach is used to investigate the relative economic advantages of pressurized water reactor (PWR) and pressurized heavy water reactor (PHWR-CANDU) nuclear power plants for hypothetical 900Mwe systems with the throwaway fuel cycle to be built in the Republic of Korea. Power cost is decomposed into the cost components related to the plant capital, operation and maintenance, working capital requirements and fuel cycle operation. The calculation of construction cost is performed with the modified version of computer code ORCOST, and the modified POWERCO-50 is used to evaluate the cost components. Most of economic parameters are treated as statistical variables, each being given with a certain range. Through a random sampling procedures. the probability histograms on unit plant construction costs and power generating costs are obtained. The power cost probability histograms of the PWR and the PHWR plants overlap considerably, and the power costs of two systems appear to be almost same with the PHWR power cost being 0.4mil1/kwh lower compared with 39.4 mills/kwh for the PWR plant (July 1986 US-dollars). When a construction period of PHWR plant is longer by one year than that of PWR plant, there is no difference in the unit power cost of two plants. This comparison leads to no definite conclusion on the cost advantage of the PWR plant versus the PHWR plant. We conclude that the selection issue of nuclear power plants in Korea still remains an open question and that future effort to solve this question should be made toward economic quantification of those factors such as technology transfer and localization.
