Current design-build contract is the type of joint venture, but performs by separate party which causes change orders due to the lack of communication between design and construction, so it cannot lead the main object which is the integration of design and construction. Furthermore, the current design-build contract is impossible to reduce the project costs by VE at the design development phase because the design proceeds with the fixed price through bidding. Like these limitless, the analysis results of the case of VE in the design-build projects, several problems that are prevented from active design VE are elicited by the project participants. Meanwhile, Ministry of Construction & Transportation decided to enlarge the VE review system lately. Therefore, in this study, it presented model of design VE partnering of design-build and partnering agreements form to apply design VE and to try to be able to lead the design VE to be more successful in public design-build projects.

Since the global financial crisis in 2008, the world economy has been suffering from the Great Recession characterized by high and persistent unemployment as well as drastic fall in asset prices. Real business cycle theory or new-Keynesian economics which has been the dominant paradigm in macroeconomics for the last four decades is unable to explain the high and persistent unemployment during the Great Recession. This implies that the economics of Keynes should be taken seriously again as a tool to explain the Great Recession. Farmer (2012) proposes a new way of interpreting the economics of Keynes by providing it with a solid micro-foundation based on labor markets with search. According to Farmer (2012), aggregate economic activity independently depends on the long-term self-fulfilling expectations about the stock prices. As a consequence, the government or the central bank should implement a policy that influences the public's confidence about the stock market. For an open economy like the Korean economy, it is not only stock price but also the price of asset such as house that matters more for the aggregate economic activity. Households in the Korean economy hold more than 70 percent of their wealth in the form of real estate asset, especially housing asset. This makes the public's confidence about the future prices of houses even more important in explaining the business cycles of the Korean economy. Policymakers should implement policies to improve the confidence of households about the housing market to recover from the recession caused by a fall in house prices. Little theoretical work has been done in explaining fluctuations in the aggregate economic activity from the point of house prices. This paper develops a small open economy model with traded and non-traded capital based on Farmer (2012) and shows that the aggregate economic activity also independently depends on the households' self-fulfilling expectations about the future prices of non-traded asset such as houses.

Despite its universal coverage of health insurance, the rural health insurance program(RHIP) stands at the crossroads in Korea. The RHIP has weaknesses in stability of financing, problems of inequities in the provision of health services and has suffered from high cost of running the program. The author has analyzed these problems from the perspective of health insurance policy and presented several options for improvement. First of all, this study urged the importance of a firm Governmental commitment of RHIP with the 50% subsidization of contributions as the Government had promised, instead of the current 40%. This can be justified from the 20% subsidization by the Government for the contributions of private school teachers and their dependents, who belong to richer segments of the population. Second, various cost containment measures ought to be sought curbing the rising demand for medical through strengthening health education and increasing individual responsibility, and tightening the claim review process. Third, this study requires the Government to run a demonstration project on the introduction of case payment system for primary health care. Fourth introducing an income-related cost sharing scheme is another possibility. Reforming the cost sharing formula for large medical expenditures is recommendable for a beginning. This measure can take the form of tax credit for medical expenditures of the poor. Fifth, the degree of financial adjustment among health insurance plans should be levelled up for enhancing stability of RHIP and social solidarity. Sixth, health policy should be redirected toward development of rural health resources and higher priority should be put on relieving difficulties in access to care. Seventh. the insurance plan owned-hospital needs to be developed or provision of health services in the medically underserved areas, and the need of such facilities is particularly acute for geriatric care, rehabilitation and renal dialysis, etc. Eighth, more generous insurance benefits are required of the elderly who are suffering the most : elimination of the maximum 180 days of benefit period and provision of glasses and artificial dentures, etc. Ninth. the economies of scale principle is working for the operating expenses of regional self-employed insurance plan. Thus, measures should be instituted to pursue an optimum size of health insurance plans. Lastly, excessive dependence on exclusion items is an evil so that some radical remedies are urgently required to cut them.

A variety of safety issues were investigated for chemical reactors using a toluene solvent in case of a fire at small to middle scale chemical plants. The issues covered the operation of pressure-relieving valves and the subsequent discharges of the toluene to the atmosphere either directly or through an absorber, which represent the current practice at most small chemical plants. It was shown that the safety valve on the reactor may not operate within about twenty minutes after an external fire breaks out, but, once relieved, the toluene vapor released directly to the atmosphere may form a large explosion range on the ground. It was also shown that if the discharge is routed to an existing absorber used for the scrubbing of volatile organic compounds or dusts, the column may not operate normally due to excessive pressure drops or flooding, resulting in the hazardous release of toluene vapors. This study proposed two ways of alleviating these risks. The first is to ruduce the discharge itself from the safety valve by using adequate insulation and protection covers on the reactor and then introduce it into the circulation water at the bottom of the absorber through a dip linet pipe equipped with a ring-shaped sparger. This will enhance the condensation of toluene vapors with the reduced effluent vapors treated in the packing layers above. The second is to install a separate quench drum to condense the routed toluene vapors more effectively than the existing absorber.

This research aims at the contribution to globalize and modernize the traditional Korean image by comprehending the taste of design that domestic college students have for traditional feminine head ornaments and subsequently elaborate the development of cultural products that are related to these decorative objects. In regards to this research method, the examination on the traditional feminine ornaments was followed through a review of literature and precedent studies and a survey was conducted on the preference about them. After the adoption of final valid responses, an analytical method, PASW 18.0, was used for frequency analysis, technical analysis, reliability, and regression analysis. The results were as follows. First, in the category of tendency analysis for the application of traditional feminine headpiece in fashion cultural products, it was revealed that a taste for the design that meet the satisfaction for both trend and practicability was prominently prevalent. Also, the design that express the individual characteristic was taken as a preferred option. Second, in the preference for the design of traditional feminine headpieces in fashion cultural products, the result indicated that the modern type was preferred in the form of re-creation as long as those products deform the tradition. As for the selective taste for patterns, their preference came in the order of plant, animal, and geometry-abstract types. Especially, for the case of plant and animal patterns, the reinterpreted design of modernized shapes were opted rather than a simply recopied format of the conventional type of the feminist head ornament. Third, for the category of item selection to apply the feminine head ornament in order to design the fashion cultural products, it turned out that people preferred the application to accessory rather than clothing. Lastly, it was found that rarity, harmony with other fashion goods, pattern, and design should be considered when the traditional motif was used for cultural products.

Construction while being an economic activity that provides facilities and infrastructure, it is beneficial to man in some aspects and detrimental in others. There have been environmental concerns related to construction activities globally which mainly focus on atmospheric emissions, depletion of natural resources and energy issues. This study was carried out to assess the impacts of construction activities on the environment in Iganga Municipality and to propose measures for their mitigation. The methodology included: review of relevant literature, observations of the general environmental effects of construction activities, focus groups and a survey conducted among construction industry role players to determine their perceptions and opinions regarding environmental impact of construction activities. The collected data was presented in tabular form and analysed by description of responses to questions. The study revealed that forests were the most greatly degraded due to high demand of timber for construction followed by wetlands degradation. The findings of this study will be useful to architects, designers and builders in order to carefully design buildings and other infrastructure that are environmentally friendly and sustainable. Construction materials and their mode of acquisition are harmful threats to the environment. There is need to reduce the consumption of these materials through recycling and reusing wastes to reduce on waste generation, use of virgin materials and the subsequent waste of energy used in new material production.

This research intended to conduct literary research on 'Jeok' of 25 jong-ga through Jong-ga Ancestral Ritual Formalities and Food, published by the Cultural Heritage National Research Institute of Cultural Heritage during 2003~2008, and compared and analyzed an arranging method and recipe transmission process by directly visiting four Jong-ga. Religious ceremony foods of Jong-ga could be divided according to the standard of the hakpa attribute (large), regional attribute (midium), and family attribute (small), which forms a complex connection structure between the attributes. 'Jeok' arranging form is divided into '3-Jeok building method (vertical structure)', '3-Jeok arrangement method (horizontal structure)', '3-Jeok replacement method', '2-Jeok arrangement method', 'Jeon-Jeok arrangement method', and 'Others-Jeok arrangement method'. Generally, 'jeok' arrangement order per hakpa is in the order of 'meat jeok - chicken jeok - fish jeok' in case of Gihohakpa, whereas Yeongnamhakpa is in the order of 'fish jeok - meat jeok - chicken jeok'. Umoringye (羽毛鱗介), the method of laying 'dojeok' of the Gyeongbuk region, could be found in the 2nd century B.C. Chinese ancient book Hoenamja and the theoretical background was Yin and yang philosophy (陰陽論). This research has significance in terms of securing advanced results compared to advanced research that has so far concentrated on some regions and hakpas.

The domestic casino industry is attempting to change from the existing single form to the advanced-type of complex casino resort. In addition, the importance of the security management system, which prevents and responds to accidents caused by negative influences of gambling, is emphasized at the casino enterprise level. Therefore, this study aimed to find measures to revitalize the security management system for domestic casinos only for foreigners through an analysis of relevant literature and case studies. As a result of the analysis, it was found that in order to effectively cope with changes in the casino industry, three areas were needed to be revamped: (1) a lack of protocols which intend to protect casino security personnel, (2) an inefficient operational system due to the dualized casino security management system, and (3) a lack of systematic educational system for casino security personnel. This study therefore proposed three measures: (1) a review of revisions of related laws to protect casino security personnel, (2) enhancement of professionalism of casino security personnel and (3) establishment of a single operating system of the casino security management operating system.

The aim of this research is a comprehensive review and evaluation of beam theories resting on elastic foundations that used to model mode-I delamination in multidirectional laminated composite by DCB specimen. A compliance based approach is used to calculate critical strain energy release rate (SERR). Two well-known beam theories, i.e. Euler-Bernoulli (EB) and Timoshenko beams (TB), on Winkler and Pasternak elastic foundations (WEF and PEF) are considered. In each case, a closed-form solution is presented for compliance versus crack length, effective material properties and geometrical dimensions. Effective flexural modulus ($E_{fx}$) and out-of-plane extensional stiffness ($E_z$) are used in all models instead of transversely isotropic assumption in composite laminates. Eventually, the analytical solutions are compared with experimental results available in the literature for unidirectional ($[0^{\circ}]_6$) and antisymmetric angle-ply ($[{\pm}30^{\circ}]_5$, and $[{\pm}45^{\circ}]_5$) lay-ups. TB on WEF is a simple model that predicts more accurate results for compliance and SERR in unidirectional laminates in comparison to other models. TB on PEF, in accordance with Williams (1989) assumptions, is too stiff for unidirectional DCB specimens, whereas in angle-ply DCB specimens it gives more reliable results. That it shows the effects of transverse shear deformation and root rotation on SERR value in composite DCB specimens.
