This study aims to analyse the method and strategy of spatial composition in the selective works of Italian architect Carlo Mollino. With the continuos renovation of the interpretative frames and method on modernity and in particular on the spatial phenomenon, works of Mollino, once disregarded by the historiography and evaluated for its peculiarity. emerge as important architectural phenomenons. The intrinsic value in his works also enable to comprehend the complexity and multiplicity of modernity in contemporary architecture. In order to achieve this preposition, six important works were analyzed with three key words, to understand comprehensively the process and the significance of each work and Mollino's contribution in the spatial composition of domestic and public spaces. Evaluation of the spatial strategies in conceptual investigations of Mollino had been underestimated to the relative poor conservation or incomprehension of various work, excluded from the categories of architectural elaborations. This study also aims to contribute, in the broad sense, the dialectical significance of modernity by emphasizing the aspects of his work related with Surrealism and vernacular tradition, as well as with its relationship with the various spatial dispositives.

In this paper we have examined the linear stability of triangular equilibrium points in the photogravitational restricted three body problem when both primaries are triaxial rigid bodies, the bigger one an oblate spheroid and source of radiation. The orbits about the Lagrangian equilibrium points are important for scientific investigation. A number of space missions have been completed and some are being proposed by various space agencies. We analyze the periodic motion in the neighbourhood of the Lagrangian equilibrium points as a function of the value of the mass parameter. Periodic orbits of an infinitesimal mass in the vicinity of the equilibrium points are studied analytically and numerically. The linear stability of triangular equilibrium points in the photogravitational restricted three body problem with Poynting-Robertson drag when both primaries are oblate spheroids has been examined by A. Kumar (2007). We have found the equations of motion and triangular equilibrium points for our problem. With the help of the characteristic equation we have discussed stability conditions. Finally, triangular equilibrium points are stable in the linear sense. It is further seen that the triangular points have long or short periodic elliptical orbits in the same range of ${\mu}$.

Coastal wetlands are among the most productive biomes in the Earth. The economic values include the direct use of a coastal wetland's ecosystem services, such as food, raw materials, recreation, and tourism. Other values comprise the indirect use of a coastal wetland's ecosystem services, such as carbon sequestration, waste-water treatment, and erosion prevention. In particular, Suncheon Bay is recently attracting attention as the most successful case of the preservation and restoration. This study applies Travel Cost Method (TCM) to estimate the economic value by drawing the demand curve for trips to Suncheon Bay. The TCM is an approach used for economic valuation of non-market goods and services. Based on the results of TCM, this study shows that the economic benefit from recreational uses of the site adds up to \174.7 billion per year. It is also significant in the sense that monetary information is suggested to help local policy makers evaluate the realistic values of coastal wetlands.

This research is a follow-up study about analysis on the many different customer groups and their various culture trend, which intends to realize diverse values depending on the sense. The purpose of this study was to develop direction forecast for the future fashion industry through consideration about the characteristics of contemporary fashion industry by the change of different customer's culture trend. And also try to find solution to survival strategy of fashion fields able to evolve with customer. Change of the customer's cultural trend draws a shift in policy in the 21st fashion industry as follows : 1) mash-up 2) complexation through decentering and blurring 3) invisible and immaterial value oriented 4) expansion of minor small market. Moreover, this shows sociocultural meaning as follows. First is spread of flexible and horizontal relationship through collaborative consumption and collaboration. Second is concentration on floating and indeterminate chance through dismantling of various different fashion categories. Third is formation of the permanent difference by selection and focus. Last is expansion of understanding about cultural-ecology. Customer cultural trend is 'meme' of cultural gene in fashion field, so it intends to co-evolute with customer by continuous change.

The buffeting response is a vital consideration for long-span bridges in typhoon-prone areas. In the conventional analysis, the turbulence and structural vibrations are assumed as stationary processes, which are, however, inconsistent with the non-stationary features observed in typhoon winds. This poses a question on how the stationary assumption would affect the evaluation of buffeting responses under non-stationary wind actions in nature. To figure out this problem, this paper presents a comparative study on buffeting responses of a long-span cable-stayed bridge based on stationary and non-stationary perspectives. The stationary and non-stationary buffeting analysis frameworks are firstly reviewed. Then, a modal analysis of the example bridge, Sutong Cable-stayed Bridge (SCB), is conducted, and stationary and non-stationary spectral models are derived based on measured typhoon winds. On this condition, the buffeting responses of SCB are finally analyzed by following stationary and non-stationary approaches. Although the stationary results are almost identical with the non-stationary results in the mean sense, the root-mean-square value of buffeting responses are underestimated by the stationary assumption as the time-varying features existing in the spectra of turbulence are neglected. The analytical results highlights a transition from stationarity to non-stationarity in the buffeting analysis of long-span bridges.

This paper examines 'an active nihilism' in Suk-je Sung's novels in detail. The focus of this study is formed from the critical mind in a critical perspective that in Korean novels before and after 2000s, characters who embody 'problematic individuals' of $Luk{\acute{a}}cs$ have disappeared and those close to 'active nihilists' has become the mainstream. The most representative example of this phenomenon is Suk-je Sung's novels. 'Active nihilists' in his novels are described as 'ascetics' who mastered various spheres such as 'billiard', 'baduk gambling', 'alcohol', 'dance', and 'book collecting', and so on. In the sense that they reject the transcendental conditions of the modern world and live in the space and time of play in which they can display their passion and potentiality to the maximum, they beings jumping over the 'reality principle'. Also, what they want to repeat is not the endless exchange of labor and capital according to the capitalist system of exchange but rather the repeated existence of their power and passion. This 'anthropology of power and passion' is 'active nihilism' which could be expressed as the 'subject of creating new value' and 'Dionysian affirmation' by Nietzsche. Suk-je Sung's novels sharply prove the stylistic essence of 'a novel' which has to create its own form every time, constantly renewing the narrative style of the past ideal model. In this respect, they are very problematic and his innovation of a form draws the attention. Further, this will certainly be the important object of research in the diachronic dimension of contemporary Korean novel.

Wargame is a simulated military operation with certain rules, specifications, and procedures, in which soldiers can virtually and indirectly experience the war. The ROK Navy operates the Cheonghae model, a training wargame model for helping commanders and staff master the procedures for conducting the war. It is important for commanders, staff and analysts to know whether a warship can perform its missions and how long it can last during a war. In existing model, the Cheonghae, the probability of kill of a warship is calculated simply considering the number of tonnage without any stochastic elements, and the warship's mission availability is also determined based on predetermined values. With this model, it is difficult to get a value of the probability of kill that makes sense. In this dissertation, the author has developed a probabilistic model in which the warship vulnerability data of ROK-JMEM can be used. A conceptual model and methodology that can evaluate the mission performance of personnel, equipment, and supplies has been proposed. This can be expanded to a comprehensive assessment of wartime warship loss rates by integrating damage rates for personnel, equipment, and supplies in wartime.

As domestic construction investment has been gradually reduced, expanding overseas construction is one of the most important issues for Korean construction companies. Among these issues, strategies for overseas CM services have widely been discussed, because the CM services have features of high growth potential and value-added area when compared with other construction sectors. Therefore, recent efforts focus on further development in advanced CM capabilities and expansion to overseas market. However, there has been lack of quantitative research to investigate current status and future direction of CM industry. In this sense, this research investigated what CM has achieved for the past 17years (between 1997 and 2013) and what CM should accomplish for future strategies. The purpose of this research is to statistically analyze total of 2,983 CM service contracts over the past 17 years published in KISCON (Knowledge Information System of Construction Industry) in order to examine current status of CM industry in terms of market type, contract size, commodity type, and owner's type. Based on this research, it is expected to suggest for future strategies and development directions from the CM industry perspective that could provide quantitative analyses, improve current CM statistics systems and strengthen the competitiveness in international CM market.

Grotesque make-up causes a visual shock among modern people beyond the standardized beauty definition, attracts their attention, and manifests itself as a phenomenon of "something bizarre, extremely unnatural, ugly, and funny." The purposes of this study were to investigate the characteristics of grotesque in today's make-up as well as its concepts and features and to figure out its aesthetic characteristics based on the results. The research scope was limited to the fashion make-up of the collections from 2005 to 2010 and the advertising make-up during the same period. In the make-up phenomenon examined according to the grotesque characteristics, the pale skin expression, frightened eyes, and emphasis on black induce disgusting fear, sadness, death, sin, fear for life and death, and obsession. As the make-up emphasized only one part by neglecting the original form and exaggerated it to the point of distortion, the exaggerated abnormality led to a sense of social crisis, desperation, and absence of form. As for devilish playfulness, the make-up accompanied by grotesqueness and humor brought the suppressed, closed world in a tight framework out to fluidity and openness, conveying satire, ludicrousness, ridicule, and accusation of the modern society. The heterogeneous disharmony was found in the use of objects in heterogeneous combinations, presenting unreality, fiction, displeasure, ambivalence, and loss of value of human existence.
