Population characteristics of Zacco koreanus were investigated at 4 stations in three National Parks of Korea from April to October 2012. Total length ranged 47mm~160 mm and weight ranged 0.50~41.50 g. Parameter b values in length-weight relationships ranged 2.883~3.497, which represent favorable conditions for habitation. Condition factor (K) had the range from 0.689 to 1.012. In relationships with sympatric fishes, the length-weight relationship (b) revealed inverse proportion to the number of species and populations. It is suggested that these differences resulted from the various factors including sympatric fishes, water temperature, seasonal changes, and surveyed stations.

Hibiscus syriacus L., the national flower of Korea, is a commonly grown ornamental species found in parks, gardens and along roadsides in Korea. This study sought to establish a plant regeneration system of H. syriacus 'Nanpa' using mature leaves as an explant. Sterilized mature leaf explants were cultured on modified MS medium with combinations of NAA and BAP at various concentrations for 6 weeks. Among the various media evaluated, modified MS media containing 0.46 mg/L NAA and 0.5 mg/L BAP (CI-1) or 0.92 mg/L NAA and 1 mg/L BAP (CI-4) were the most effective for callus formation. Whitish-yellow calluses were observed on CI-1 medium, while green calluses formed on CI-4 medium. The whitish-yellow callus derived from CI-1 medium showed a higher frequency of shoot induction than the green callus derived from CI-4 on modified MS medium containing 0.5 mg/L BAP. Among the various media evaluated in this study, modified MS medium containing 0.46 mg/L NAA and 0.5 mg/L BAP was the most optimal for shoot-forming callus production. Our findings show that mature leaves of H. syriacus 'Nanpa' can be used for in vitro plant regeneration, and the regeneration system described here may be a powerful tool for molecular breeding of H. syriacus 'Nanpa' in the future.

As the national interest in sports has been increased over time, sports facilities and sports complex are considered more than just physical environments for training athletes or watching games. Sports facilities now become symbolic spatial devices to represent the national and cultural pride of any countries. The existing national training camp located in Taenung, Seoul is gotting outdated and degraded. The polluted air in the city risks athletes' health condition. The government planned to construct the second training camp at Jincheon, Chungbuk at the area of $2,171,910m^2$. The Korea Sports Council called for proposals to envision the future training camp, and they held a design competition from August to November, 2005. The first phase was to present the masterplan for the entire site including training buildings, outdoor training facilities, dormitories, a visitor center, a research center, education and administration buildings. Considering the size of the site, the planning process required a strong relationship between landscape and architecture. This study tries to provide general explanations on the winning proposal focused on the landscape-related issues. It also attempts to have reference points for contemporary planning and design issues to situate the project in the stream of continuing design effort to avoid the dichotomy between nature and culture. The landscape proposal for the new national taming camp suggests four main strategies; 1) The camp has two intersecting and interweaving parks which represent the natural and urban order. 2) The entire site is organized and networked by the flow of landscape called landscape ribbon in terms of topography, vegetation, and water flow. 3) The landscape is choreographed through the time and process. 4) The ecological process and the digital contents are juxtaposed in the landscape. This winning proposal is the first step to portray the national vision for the sustainable environment coexisting with sports industry. Landscape in this proposal is an active agent to network various parts of the site which enables landscape to be infrastructure. Landscape design in this proposal should be considered open-ended strategies rather than determined concrete forms and its engaging further development will be tested in following Design-Build phase.

National parks provide recreation, health, and science to human being. The provision of beautiful landscape view of the national park improves an economic and social phase of a nation. However, visibility impairment frequently occurred in the national park area of Gyeongju. The purpose of this study is to investigate the physical and the chemical characteristics of visibility reduction observed at the national park area of Gyeongju. Optical, chemical, meteorological characteristics and scenic monitoring were performed at the visibility monitoring station of Gyeongju University located at the Seoak section of Gyeongju national park from April 28 to May 9, 2008. Light extinction, light scattering, and light absorption coefficients were continuously measured using a transmissometer, a nephelometer, and an aethalometer, respectively. In order to investigate the impact of aerosol chemistry on visibility impairment, size-resolved aerosols were collected at intervals of 2-hour (from 8 A.M. to 6 P.M.) and 14-hour (from 6 P.M. to 8 A.M.) interval each sampling day. The average light extinction coefficient and the average visual range were measured to be $270{\pm}135\;Mm^{-1}$ and $14.5{\pm}6.3\;km$ during the intensive monitoring period, respectively. It was revealed that sulfate particle was the largest contributor to the light extinction under hazy condition. Organic mass accounted for about 26% of the average light extinction. The mass extinction efficiencies for $PM_{1.0}$, $PM_{2.5}$, and $PM_{10}$ were estimated to be 9.0, 4.7, and $2.7\;m^2\;g^{-1}$ under the consideration of water growth function of hygroscopic aerosols, respectively.
