Typhoon induced surge simulations are done to make an establishment of coastal disaster prevention plan. To apply efficient run-up and overtopping on vertical harbor docks, in which prevailing wet-dry scheme cannot be satisfied due to infinite steepness, an imaginary internal barrier concept introduced and analyzed. Before real application on the Mokpo harbor area, feasibility tests are done on an idealized simple geometry and as a result it is found that the moderate width of the barrier might be 1 m. The threshold value of the minimum wet depth $H_{min}$ for land area, which behaves sensitive role in inundation area and depth, depends on grid size. However it is revealed that 0.01 m is adequate value in this fine finite element with 10 m spacing. A hypothetical typhoon of 100 years return period in central pressure and maximum velocity is generated based on historical tracks. Simulation of possible inundation on Mokpo area is performed with asymmetrical vortex of hypothetical typhoon and wave coupling. Model results show general agreement in pattern compared to other's prediction, however possibility of inundation enlargement is expected in harbor area.

TExhibiting replicas of major artifacts is becoming common recently to raise their value and help the public to understand them. In Korea, more attention is paid only to appearance in creating replicas of artifacts. It is required to study reproduction technology minimizing damages to originals and applicable to massive artifacts like sculptures in the situation that replicas and artifact reproduction is increasing. To make a replica of the Stone Lion Statue excavated from Woljeong Bridge, a measured drawing and a cross section are produced based on art historical surveys using 3D scans. A non-contact reproduction method is selected. The strength of the non-contact reproduction method is that the output is detailed. Athough the non-contact method has known to be applicable only to small scale artifacts and require reprocess, it is discovered to be applicable to detailed statues like this lion statue. Therefore, this study may contribute to complement the historic authenticity of the statue as well as to raise its academic value. It also can be utilized as research material of similar artifacts'replicas and restoration.

Recently, the material industry in the world has started appreciating the value of new materials that can overcome the limitation of steel material. In particular, new materials are expected to play a very important role in the future industry, demonstrating superior performance compared to steel in lightweight materials and ability to maintain in high temperature environments. Carbon materials have recently increased in value due to excellent physical properties such as high strength and ultra lightweight compared to steel. However, they have not overcome the limitation of productivity and price. The carbon materials are classified into various composites depending on the purpose of use and the performance required. Typical composites include carbon-glass, carbon-carbon, and carbon-plastic composites. Among them, carbon-carbon composite technology is a necessary technology in aviation and space, and can be manufactured with high investment cost and technology. In this paper, in order to find the optimal conditions to achieve productivity improvement and cost reduction of carbon material densification process, the correlation between each process parameters and results of densification is first analyzed. The main process parameters of the densification process are selected by analyzing the correlation results. And then a certain linear relationship between major process variables and density of carbon materials is derived by performing a regression analysis based on the historical production result data. Using the derived casualty, the optimal management range of major process variables is suggested. Effective process operation through optimal management of variables will have a great effect on productivity improvement and manufacturing cost reduction by shortening the lead time.

We study the operation of a lunisolar calendar in Korea and its time data calculation method. The dates based on the lunisolar calendar have been conventionally used in Korea after the Gregorian calendar was introduced in 1896. With the Astronomy Act enacted in 2010, the lunisolar calendar is presently being used as an official calendar along with the Gregorian calendar. However, no institutionalized regulations have been provided on the time data calculation method by the lunisolar calendar. The Korea Astronomy and Space Science Institute very recently established the regulations on the lunisolar calendar operation in Korea. We introduce the regulations together with historical substances and analyze the time data calculated according to the regulations for 600 years from 1901 to 2500. From our study, we find that the value of ${\Delta}T$ (i.e., the difference between the terrestrial time and the universal time) is the most critical parameter causing uncertainty on the data. We also find that all new Moon days in the almanacs agree with our calculations since 1912. Meanwhile, we find that new Moon and winter solstice times are found to be very close to midnight in 38 and five cases, respectively. For instance, the new Moon time on January 14, 2097 is 0 h 0 min 8 s. In this case, deciding the first day (i.e., new moon day) in a lunar month is difficult because of the large uncertainty in the value of ${\Delta}T$. Regarding with a lunar leap month, we find that the rules of inserting the leap month do not apply for 17 years. In conclusion, we believe that our findings are helpful in determining calendar days by using the lunisolar calendar.

Korea began preserving and managing natural monuments in 1933 under the Japanese Colonization, but South and North Korea had to establish natural monument management policies separately because of the division after the Korean Independence. The purpose of this study is to compare and analyze the natural monument designations of South and North Koreas between 1933 and 2005 to introduce advanced polices for Oneness-Korea. The following are the results: According to data of December 2005, South Korea has 358 and North Korea has 474 natural monuments. North Korea has 116 more natural monuments than South Korea. In addition, over half of South Korea's designations are plants, whereas North Korea's designations are relatively well-balanced. Both South and North Korea designate plants(mostly trees) that are old and large. However, South Korea emphasizes the historical value of village forests, contrary to economic value in North Korea. Also, North Korea preserves many traditional fruit trees which have not been well-preserved in South Korea. As for animals, South Korea designates migratory wild animals by type and not by region to protect them at a national level, whereas North Korea designates the specific habitats of each type of wild animal. In addition, North Korea protects each region's cattle and chickens to preserve native traits of domesticated animals. Geologically, North Korea preserves 18 hot springs and 11 springs, whereas South Korea has none. Geographically, North Korea preserves 81 waterfalls, lakes, etc. In the conclusion, advanced natural monument management of South and North Korea is necessary to achieve effective preservation of natural monuments.

The purpose of this study is to apply the Trencadis images in Antony Gaudi's work to a design motive and thus provide a new concept for a knitwear design by combining double-knitted fabrics with patchwork applique, taping, stitching and quilting. This study examines the bibliographic text and precedent research related to Antony Gaudi and his works, and analyzes the historical background and formative and stylistic characteristics of Trencadis as it appeared in Gaudi's architectural works. Also this study also examines the characteristics of knitwear and knitting theory while exploring the formative elements and the combined techniques used in modern knitwear design through fashion magazines, medium images, and online sources. The results are as follows: First, Gaudi's work that applies a Trencadis technique has the characteristic of being creative, organic, and environmentally friendly. And in addition, its colorfulness inspires modern fashion design. Second, computerized knitting has been practiced in various ways and the fabrics knitted by both double-knitting jacquard and computerized knitting machines provide a new direction the creation of knitwear. A computerized knitting machine is especially effective for pictorial expression, and is suitable for showing the natural curve of the human body due to its sophistication. Third, as a result of applying a combined technique to the knitting of various fabrics, a combined or fusion design, which is a recent megatrend, is very effective for the design of knitwear while increasing its aesthetic value. Moreover, utilizing techniques that combine patchwork applique, taping, stitching and quilting will create higher value in knitwear. Lastly, with a project of applying combined techniques in the creation of knitwear, designers can become much more creative while taking their imagination much further.

The purpose of this research is to reveal the problems of the Western based development discourse, and to derive the future direction of postdevelopment as sustainable development. This study attempted to reveal the historical process of formation and change on development discourse. Development generally regarded as the overcome of underdevelopment, inducing the marginalization of the South as a place to follow the development model of the North. State based development discourse (Keynesian development discourse) focused on the growth by industrialization, and the supreme aim of the South was to overcome the underdevelopment. Neoliberalism development discourse emphasized on the market principle based on free competition which was recognized as the best way to provide development. However, neoliberalism discourse has been criticized for the concentration of power and inequality of class, causing on the consideration of postdevelopment because of its emphasis on growth rather than distribution and life value. This research revealed the ways of postdevelopment with fair trade and ethical consumption. However, fair trade and ethical consumption discourses clearly show somewhat limitation subsuming into neoliberal development discourse. In this respect, future ways for postdevelopment have to consider the overcoming of powers based on market and capital, and to orient into the value of redistribution in development process.

Is it lawful to withhold or withdraw life-sustaining treatment applied to a patient in a terminal condition or permanent unconscious condition? In Korea, there are no such laws or regulations which control affairs related to the withholding or withdrawal life-support treatment and active euthanasia as the Natural Death Act or the Death with Dignity Act in the U. S. A. And in addition there has had no precedent of Supreme Court. Recently Supreme Court has pronounced a historical judgment on a terminal care case. The court allowed the withdrawal of life-sustaining treatment from a patient in a permanent unconscious state. Fundamentally the court judged that the continuation of that medical treatment would infringe dignity and value of a patient as a human being. And the court required some legal grounds to consider such withdrawal or withholding of medical care lawful. The legal grounds are as follow. First, the patient is in a incurable and irreversible condition and already entered a stage of death. Second, the patient executed a directive, in advance, directing the withholding or withdrawal of life-support treatment in a incurable and irreversible condition or in a terminal condition. Otherwise, at least, the patient's will would be presumed through his/her character, view of value, philosophy, religious faith and career etc. I regard if a patient is in a incurable and irreversible condition or in a terminal condition, the medical contract between a patient and a doctor would be terminated because of the actual impossibility of achievement of it's purpose. So I think the discontinuation of life-sustaining care would be legally allowed without depending on the patient's own will.

This treatise studies on how ideology and value of Chinese minority race undergo change according to social, political transition that the Chinese minority race has experienced for a long time and I also have tried to elucidate how these kinds of their experiences have been effected upon their own life, even it is part of my basic subjects for my study. Hence I would give weigh to focus on contemplating process of the past and the present rather than predictive discussion of how their pursuing value will be transformed. For my ebullient study, I'm willing to make Yi-Zu's moral culture become axis of my treatise, and capitalize on not only how Han-Zu's ideological philosopies have been disseminated, but also how acculturation have been taken place in Yi-Zu's moral culture system. Yi-Zu has the longest history and the greatest their own population, even the largest residence of various Chinese minority races. And Yun-Nan is the historical place where not only various Chinese minority races have lived, but also acculturation between Chinese majority, Han-Zu and them have been begotten. Above all, I would delve into traditional religion to understand Yi-Zu's moral culture as was already mentioned that it is my axis of treatise. Furthermore, I deliberated on how Taoism have been infiltrated Yi-Zu's moral culture, also how Han-Zu's ideological philosophies have been permeated Yi-Zu's, and what is more how to help themselves still remained in Yi-Zu's. Through my such these efforts, I analyze the aspect of embracing of Han-Zu's moral culture by Yi-Zu's and some facts of vicissitudes about it.
