This aim of this study is to support the value criteria that citizen evaluate themselves it when they found modern heritages in their town. To understand the changing of value criteria for the cultural heritage, we have to begin from early 20 century that were, however, diversified after 80's. As a result, early they evaluated with the architectural and aesthetic value mainly, after they evaluated with the social-cultural value and academical value, and nowadays they try to include the economical value and educational value. So this study rearranged and divided that value with the preservation and using value. The preservation value include the historical value, aesthetic value, social-cultural value and academical value, and the using value include the economical value and educational value. The criteria, however, don't have the equal importance, This study try to redefine relative importance score with paired comparison. As a result, Historical value is proved that most important criteria, but aesthetic value got the score lower than social-cultural value, and similar with academical values. And in using values, economical value and educational value got the low score. It means that if some researcher insist about the importance of economical value, it should evaluate lower than preservation values. This study insist that we have to include diversified values and that values have relatives score. Actually, now we mostly evaluate with the architecture and aesthetic values about modern heritage, so we are losing a lot of modern heritage. If we include the diversified values, social-cultural, academical and educational value, we can conserve our important modern heritage and revitalizing town with tourism of historical heritage.

The corrosion product of archaeological iron objects is supposed to be removed because it causes re-corrosion. So far it is removed by scapel and sand blaster but they depend on the skill and experience of a conservator and the glass-dust of the sand blaster is harmful to humans. Therefore this study applies a laser cleaning system which is used in various industrial cleaning processes, to remove corrosion product from archaeological iron objects. In addition, this work studies the alternation of corrosion product after laser irradiation, which evaluates the reliability of the laser cleaning system. Optical microscopy, SEM-EDS, XRD, Raman have been used to observe and analyse the surface of the objects. The results show the capacity of laser cleaning some corrosion product, but blackening appears with increasing pulses and laser energy, and some corrosion products, goethite and hematite, are partially altered to magnetite. These problems, blackening and alternation of corrosion product, should be solved by further studies which find the optimal laser irradiation condition and use a wetting agent.

Oegosan Onggi Village can be characterized by having industrial significance and cultural significance of Onggi. However Onggijang(Onggi maker) worked in poor conditions because the village was in the limited development district. Throughout the new millenium phenomenon of Well-being, the awareness of cultural values has been increased while local government designated Onggi as Local Intangible Cultural Heritage(ICH). In this condition, Ulsan metro city and Ulju county paid attention to Onggi Village as tourist attractions. First, they worked improving condition of village through Cultural Tourist Attraction Plan. Second, they extended their participation in Onggi Festival so the festival growed. Third, they designated Onggijang in Village as Local ICH. These activities were the effort in order to revitalize the village, however the cultural tourist attraction plan was solely centralized into tourist attractions. Thus, the work condition of Onggijang was not considered sufficiently so the work condition had become more inconvenient than the previous situation. In the case of Onggi festival, the outward development has been accomplished in accordance with the growth of festival scale and visitors, while the identity of festival had been weaken so the Onggijang barely attended the Onggi festival. The designation of ICH was also the unilateral decision, Onggijang had been in the conflict relationship between Onggijang concerning the craftsmanship and maintenance of the ICH. Local Government had power on their Intangible Cultural Heritage(ICH). Therefore we need to seek for role and functions as community on ICH.

This study aims at evaluating the characteristics and the preference on the sign design in the industrial heritages space. The research were performed by the process of literature review, case study, and survey of questionnaire. Seven industrial heritage space in Korea and China regenerated as art and cultural space after 2000 were selected and evaluated by 6 criteria including integrity, continuity, simplicity, aesthetics, legibility and historic aspects. The findings were the following. First, the six criteria factors were evaluated as the similar scores in the assessment of 7 sites without extremity. Simplicity was the highest score while historicality was the lowest one. It means that the characteristics of the sign systems of the heritage sites were focused on the simple, contemporary and effective design. Second, integrity, continuity, aesthetics, legibility were evaluated as the medium score in the sign design. While, in the evaluation on the aesthetics the score differences were comparatively high. Sanhai M50 which got the highest score showed the integrity of contrast using yellow and grey color with minimal design. However, Sanghai M50 got the lowest score in the historic aspects and was evaluated as the most favorite sign design in the preference. It means that the historic aspects have no direct relationship with the preference for the sign design. It shows that the effectiveness with integrity and the aesthetic aspects are considered more importantly than the application of the historic identity of the site in sign design.

Korea's Rolling stock workshop were established with the introduction of a railway, and became the center of industrial construction in the modern age of Korea. There still exist a lot of Rolling stock workshop buildings in the Youngsan Rolling stock workshop, the representative case of Korean Rolling stock workshop, and especially the study aims to look into modern architectural properties centered on those well-preserved buildings. Korea's Rolling stock workshop were built considering the proper conditions of location such as the neighboring districts from the port to transport vehicles and materials, the place where railroad lines are centralized, the short returning distance of railroad cars for entry and departure, and had the facility layout according to the order of a working process of vehicles, and the unique structure and the section facade shape with proper functions and sizes according to each purpose. In particular, they actively adopted steel-frame structure and reinforced concrete structure, and came to have the initial characteristics of Korea's modern industrial building which is called the structural transition. Therefore, this study aims to highlight the importance of Rolling stock workshop including the Youngsan Rolling stock workshop as industrial architecture heritage in the modern age of Korea.

To isolate and identify the yeast strains associated with D. morbifera, homogenized D. morbifera root samples were spread onto GPY, DG18, SCG and DOB agar media containing antibiotics, Triton X-100, and l-sorbose. Total 81 yeast isolates were analyzed by sequencing of internal transcribed spacer (ITS) region of the ribosomal DNA. The results showed that the root-associated yeast species were composed of the genera Vanderwaltozyma (40 isolates), Cryptococcus (40 isolates), and Kluyveromyces (one isolate). Moreover, the Kluyveromyces isolate exhibited high bioethanol productivity. In addition, the Vanderwaltozyma and Cryptococcus were dominant in D. morbifera roots. The specific yeast community associated with D. morbifera roots was identified by phylogenetic sequence analyses. These yeast isolates may have industrial applications as biosurfactant and bioethanol.

Inter-Korean Economic Cooperation needs to a different strategy for developing synergy effects, suggesting they should be selected for role to the unification Korea. In the this paper, Three policy-strategies is suggested as follows. Firstly, Economic Cooperation Driving Committee of Inter-Korean Digital Cultural Content is necessary the recovering of cultual consubstantiality and the operating of business partnership in the divided peninsular. Secondly, To cultural contents cooperation between South-North Korea. the exchange of learning and information must be activated constantly. as the cultural contents is creative industrial, it needs for imagination and creative of human and understanding of a fine arts, a traditional arts. Thirdly, A policy and system is inevitable to construction of Inter Korean Cooperation Digital Contents. South-North Korea, including a North Korea having a excellent cultural heritage, must jointly recovery for cultural contents. Under social-economic system, a consumers of digital contents pay to the format creator many royalty. Therefore, We must prepare to roll out a series of new creative contents, and have competitive advantages in the global market.

The wooden building is mainly damaged by the termite which have an effect of the structure by making emptied inner part of wood. One class, Japanese termite, inhabits throughout Korea and is often detected. So the deterioration by termite attacking the wooden building needs to be controlled. Termites are over 2,800 species in the world, usually they inhabit in the tropical or subtropical region and don’t over winter in dormant condition. So their activity and distribution are chiefly restricted by temperature and humidity. The termite inhabiting in Korea is Reticulitermes speratus kyushuensis Morimoto, which known to have an optimal temperature range at $12~30^{\circ}C$ and minimum temperature at $6^{\circ}C$ for activation. These temperatures correspond to the mean temperature($5.6^{\circ}C$~$25.8^{\circ}C$) from March to November and the activity time of termitein Seoul. In addition, as a result of environmental pollution by industrial development, the climate of Korea is getting warm. The increase of mean temperature in Korea has been $1.1^{\circ}C$ for the past seventy five years, so it is expected that the damage of wooden building by termite will increase gradually. Therefore, in order to protect wooden building from damages by termite, it needs not only development of new pest control methods, but also studies on the control of environmental factors having an effect on the activity and growth of termite. For the conservation of the large cultural properties such as the wooden building in the open air, it would be effective to use the methods of fumigation, insecticidal and antiseptic chemical treatment of wood materials, soil termiticideinjection treatment, and termite colony elimination system.
