The aim of this study is to compare open space planning between Australia and Korea by Local Governments Areas. Open space planning is carried out at the state and municipal level in Australia, but by metropolitan city government in Korea. This study is structured by reviewing the presemt phenomena of provision of open space in Sydney and Seoul, By measuring disparity in terms of open spaces by L. G. A. s an by comparing planning approaches between two cities, for example policy, government standards, government administration system in open space management. In this paper, the provision of parks in Sydney and Seoul are comparatively examined and geographically mapped, and multiple repression analysis is applied to measure the residuals from the line of equality. The results of this study show that, 1) During the last 1 dacade from '80 and '90. Sydney has increased the quantity of open spaces from ratio of 19.11ha/1000 to 22.33ha/1000 of parks, however Seoul decreased it by the ratio of 12.21$m^2$/person to 1012$m^2$ per person. 2) Sydney has more programs, such as Greenspace program, Metropolitan open space program etc. to increase and to distribute open spaces equally rather than Seoul which has less open spaces. 3) There exists patterned inequality in terms of open space provision in inner city and suburb between Sydney and Seoul. 4) Seoul requires more active polices to increase open spaces like Greenacre Program of New Jerrsey State, Double Open Space Pland of Tokyo or Green Space Program of Sydney.

This report describes the first prize design of Midongsan Eco-park, which is located in Chungcheongbuk-do (North Chungcheong) province. Criteria of the winning design are as follows: 1) The design should include a neighborhood park as well as a portion of a green zone, in order to harmonize the area ecosystem, gradually assimilate the surroundings, and serve as an education tool for the public. 2) According to an analysis of area maps and a site-inspection, a preserved area, a buffer area, a restored area, and a developed area should be developed. In the buffer and restored areas, major facilities and activity spaces should be set up. 3) Observation trails should be accessible to visitors, and a variety of adventure programs should be available. 4) The eco-park should be designed to provide a habitat for the Gorani (Chinese water deer) which used to live around Midongsan. 5) For sensuous and vivid visitor experiences, diverse programs are to be designed to accommodate different seasons, visitor ages, and required time. Environment and eco-education are to be emphasized to maximize the effect of the eco-programs. 6) Optimal activities for visitors of different ages, optimal time intervals and eco-programs by age are also suggested. 7) Facilities are zoned into three sections according to level of development. Each section has a main area and supplementary areas for better understanding. 8) Nature-friendly arrangement of facilities and construction should minimize earthwork and adverse effects on the local ecology. Throughout the planning, the following things were learned: longer-term analysis including all season's observation is essential; planning, designing, bui Iding and managing should be based on this careful, extended observation. The contest should have taken plate over a longer period of time in order enable more detailed planing of the eco-park For improved management and activities, a volunteer system in linked with schools eco-institutions and NGOs should be developed with eco-interpreters.

This study estimates the greenhouse gas (GHG) emissions reduction resulting from photovoltaic and wind power technologies using a bottom-up approach for an indirect emission source (scope 2) in South Korea. To estimate GHG reductions from photovoltaic and wind power activities under standard operating conditions, methodologies are derived from the 2006 IPCC guidelines for national GHG inventories and the guidelines for local government greenhouse inventories of Korea published in 2016. Indirect emission factors for electricity are obtained from the 2011 Korea Power Exchange. The total annual GHG reduction from photovoltaic power (23,000 tons CO_2eq) and wind power (30,000 tons CO_2eq) was estimated to be 53,000 tons CO_2eq. The estimation of individual GHGs showed that the largest component is carbon dioxide, accounting for up to 99% of the total GHG. The results of estimation from photovoltaic and wind power were 63.60% and 80.22% of installed capacity, respectively. The annual average GHG reductions from photovoltaic and wind power per year per unit installed capacity (MW) were estimated as 549 tons CO_2eq/yr·MW and 647 tons CO_2eq/yr·MW, respectively. Finally, the results showed that the level of GHG reduction per year per installed capacity of photovoltaic and wind power is 62% and 42% compared to the CDM project, respectively.

Leaf spot symptoms were observed in a commercial Palenopsis cultivated fields. Circular-elliptical watersoaked spots surrounded by a light green or yellow halo and turned to black when it was severe infection or blacken with gathered symptoms. These spots were finally enlarged to form of larger areas. Under the favorable conditions of temperature and moisture, the infection extended rapidly and dispersed to the crown and sometimes the infected plant became dead. A bacterial organism, isolated from the advancing margins of the lesions, was tested to characterize causing bacterium based on pathogenicity. The biochemical and physiological tests of that bacterium identified that as an Acidovorax avenae subsp. cattleyae. Therefore, we suggested to call that the new Phalaenopsis disease was bacterial brown spot caused by A.avenae subsp. cattleyae in Korea.

This study aims to analyze the accidents of green mode bicycle. In pursuing the above, this study gave special emphasis on modeling the bicycle accidents reflecting the regional characteristics. The main results are as follows. First, the null hypotheses that the number of accident and ratio of serious injury and fatality (FSI) were the same over regions were rejected. Second, as the common variables, the number of bicycle was judged to have positive (+) impact to the accidents and the bicycle using ratio was inferred to increase the ratio of FSI. Third, the elderly population ratio among 3 factors which gave impact to the accidents of Si_A (city-county consolidation) was concluded to have the greatest elasticity. The developed area ratio between 2 factors in Si_B (city which is not consolidated) was, however, estimated to have the higher elasticity. Fourth, the number of car registration among 5 accident factors of Gun (county) was analyzed to have the greatest elasticity. Finally, the commuting trip ratio among 7 accident factors of Gu (district) was judged to have the greatest elasticity. This study can be expected to give some implications to regional policy-making related to bicycle.

Protection of tropical forest affects on significant reduce of tropical hardwood supply, and softwood resources will be increasingly important for the timber security in Korea. U.S. softwood log was most favorite species for Korean softwood log importers in overall import conditions except price stablization and consistency of export policy. Reduced export volume from Pacific Northwest to Korean market has been immediately replenished by rediata pine from New Zealand and Chilean plantation. Siberian timber will hardly play major roles in Korean timber market unless budding structure. softwood plywood and softwood furniture uses are enhanced. Recent rapid rise of labor cost and reducing tariff rrate in Korea provided better opportunities for import lumber in building materials market. Dry dimension lumber was relatively profitable when processed from import U.S. soft-wood log while green lumber was favorable products processed from radiata pine log in Korean lumber market. This means U.S. softwood lumber would have better opportunity to market for '2${\times}$'4 studs when wood frame housing is introduced. On the other hand while radiata pine is competitive on temporary construction lumber such as supporter and concrete forming frame in Korea. Shortage of raw material for the new capacity of board plants in Korea will be it bottle neck. Major log export countries to Korea as U.S. New Zealand and Chile showed high trade intensity indices of composite hoard produces for Korean market. As Korea efforts to diversify import sources, and tariffs are reduced to 8% as scheduled by 1994. countries of scoring higher comparative advantages as Portugal. Brazil, Austria as well as New Zealand will have better opportunity to penetrate into promised Korean composites hoard market.

Since the beginning of 2000, the ubiquitous technology rapidly has been at center of public concerns, and application of the ubiquitous technology is expanding in Korea with U-City as the center. U-City is currently planned and built by local governments, but the applicable range of the ubiquitous technology should be expanded in the future to build U-Territory and U-Land projects. As a part of this, U-forest should also be implemented, and that now is the time to gain support in policy and systematic initiative. Therefore, this study defines U-Forest concept to implement valuable national resources, healthy land environment, and pleasant green space by using ubiquitous technology as an effective way to produce, manage, use, and distribute the forest. In order to establish strategy for U-Forest, it has considered basic forest plan, k-Forest, and FGIS projects, and has drawn a service model pertaining to them. Also, it has proposed the need to establish the basic plan for U-Forest, and suggested details to include in the plan.

We suggest new emitter formation method using solid-phase epitaxy (SPE); solid-phase epitaxy emitter (SEE). This method expect simplification and cost reduction of process compared with furnace process (POCl3 or BBr3). The solid-phase epitaxy emitter (SEE) deposited a-Si:H layer by radio-frequency plasma-enhanced chemical vapor deposition (RF-PECVD) on substrate (c-Si), then thin layer growth solid-phase epitaxy (SPE) using rapid thermal process (RTP). This is possible in various emitter profile formation through dopant gas ($PH_3$) control at deposited a-Si:H layer. We fabricated solar cell to apply solid-phase epitaxy emitter (SEE). Its performance have an effect on crystallinity of phase transition layer (a-Si to c-Si). We confirmed crystallinity of this with a-Si:H layer thickness and annealing temperature by using raman spectroscopy, spectroscopic ellipsometry and transmission electron microscope. The crystallinity is excellent as the thickness of a-Si layer is thin (~50 nm) and annealing temperature is high (<$900^{\circ}C$). We fabricated a 16.7% solid-phase epitaxy emitter (SEE) cell. We anticipate its performance improvement applying thin tunnel oxide (<2nm).

The study looks at the development of new & renewable technology in a latecomer country, Korea. The main question is whether the development is driven by 'green demand' from the people or by the 'growth demand' from the industry. It also asks what are the characteristics of socio-technical constituency behind the development of new & renewable energy technology; growth-centered or environment-centered. It is found out that a 'New & renewable energy technology socio-techical constituency', consisted of NGOs, industry and government in the form of membership to New & Renwable Energy Policy Council of the government program, was established driving the development of new & renewable energy technology development in Korea. Yet, the coalition among them was based on 'the desire for growth' rather than 'the concern for environment'. The changes in authoritarian development state such as the adoption of governance approach to public decision-making process also contributed to the formation of the constituency.

Today, the hotel industry in a whole are facing serious problems with a number of reasons. To overcome this situation, Customer-Oriented Marketing is considered to be a solution for the hotel F & B management, due to the potential of F & B department. The main purpose of this study was to present the Food and Beverage Marketing Mix Strategies suitable for the market characteristics. To achieve the purpose of this study, theoretical and empirical approaches were used. In review of theoritical background, basic concepts and characteristics of hotel F & B, hotel F & B marketing environment, and hotel F & B marketing mix were studied. Based on the theoritical studies and previous studies, F & B marketing mix sub-components were chosen. In this research, F & B 5P's and 1I marketing mix are discussed, they are Product, Price, Promotion, People, Physical evidence and Image. Through the survey, a number of important segment markets are emerged, which lead to essential segment markets ; business, conference and leisure market. F & B marketing mix strategies as follows. First, for the physical evidence mix, to build up the position as deluxe hotels, it is necessary to matte an investment in technical and decorative components. Second, for the people mix, to assure the service quality, the education and training programs for employee are required. Third, for the image mix, to ensure the image of hotel brand strength, the consideration for public area layout, restaurant and bar ambience, and green policy are required. Fourth, for the product and price mix, to differentiate the F & B, it is necessary to offer thorned and ethnic cuisine, and signature restaurants. Fifth, for the promotion mix, to attract more cumstomers, creative and various promotion activities, and long-term investment in customer-oriented marketing are required. There were some limitations in this study. That is, most of hotels don't operate the concrete and effective F & B marketing, have difficulty in getting data base for F & B customer. Despite their limitations, this study add some values to hotel F & B management in that it introduce the service marketing mix strategies to hotel F & B marketing.
