Invasive species are organisms that are introduced into places outside of their natural distribution range. The global pet trade is facilitating the introduction of invasive species into new countries and areas. Among the introduced alien species, turtles are one of the most common animal groups whether lives in wetland ecosystems, such as wetlands or reservoirs. Like other countries around the world, exotic turtles is becoming a growing concern for the wetland ecosystem in South Korea. In this study, we report new reports of subspecies of Painted turtle (Chrysemys spp.): Chrysemys picta marginata, C. p. bellii and C. dorsalis, from the reservoirs in downtown Cheongju and Gwangju, South Korea. We used morphological features, such as the characteristics of the legs, plastron, and carapace, to identify the turtles. It is assumed that all turtles were artificially released into nature. Considering the increasing number of reports on the introduction of alien invasive turtles in Korean wetlands, we recommend the formulation of an immediate and systematic management plan for pet trades and organized continuous monitoring programs.

Black carbon concentrations were measured along the altitude at various locations using a drone coupled with a small black carbon detector. The measurement locations are Eunseok Mountain, downtown, four places in KOREATECH campus, Byeongcheon, Cheonan, Chungcheongnam-do, and Chungbu Expressway in Ochang-eup, Cheongju, Chungcheongbuk-do. The average concentration of black carbon measured in Eunseok Mountain was $1.64{\mu}g/m^3$ and the average concentration near the Chungbu Expressway was measured to be $3.86{\mu}g/m^3$. The average concentrations of four places inside campus ranged from 1.37 to $2.67{\mu}g/m^3$. The concentration of black carbon at all places tended to be slightly decreased according to the altitude, but the influence of pollution source, geometry, wind speed, and wind direction are thought to be larger than the effect of altitude. Effect of air flow caused by drone flight on the measurement of black carbon were investigated and it resulted in that the measurement of BC concentration was affected by less than 5%.

The purpose of this study is to derive and to apply green factors focusing on the existing old settlements, Topdong 'Yangdalmal' in Cheongju City. This study is conducted through literatures and GBCC (Green Building Certification Criteria) review. Literatures cover the traditional characteristics of farming village and the modern characteristics of urban space today. The results are following as; first, Land Use, Environment, Resource and Energy are the most important green factors by literatures and GBCC. Second, traditional elements and natural elements such as history and culture, natural resource use and passive planning are added. Finally information communication is added as the green factor showed feature of modern society.

많은 기회요소와 편의성이 존재하기 때문에 도시에는 많은 인구와 건물이 집중되어 있다. 이러한 이유로 인하여 재해 발생 가능성이 높고 재해가 발생하면 그 피해는 치명적이다. 본 연구는 우리나라 도시특성에 맞는 실용적인 재해 위험도 평가방법을 제시하는데 있으며, 사례지역으로 충청북도 청주시를 대상으로 평가하였다. 화재위험도, 건물붕괴위험도, 대피위험도, 가스폭발 위험도를 포함한 종합위험도를 분석하고 적용한 결과, 현재 도심공동화 현상이 나타나는 북문로 일대가 위험성이 가장 높게 나타나는 것으로 분석되었다. 이 일대는 구시가지로 재난의 대책 및 정비가 이루어지지 않았음을 예상할 수 있으며 시급한 정비가 이루어져야 된다고 판단된다.

The purpose of this study is to analyze the perceived service quality according to the characteristics of beauty salons and customer demographics. 343 customers were surveyed in the areas of university campuses, central district and residential areas of Cheongju. The questionnaire consisted of the characteristics of beauty salons and customer demographics, and items to evaluate the service quality. Confirmatory factor analysis, t test, ANOVA and descriptive statistical analysis were used to analyze the data. The results were as follows; First, the preference for the number of designer in the beauty salon were differed by sex, age and occupation. Women, college and graduate students preferred the salons with over seven designers. The customers over forty years old used smaller beauty salon. Second, Female perceived higher service quality in all respects such as technique, kindness and convenience of reservation than male did. There were no difference in age groups and occupations. Third, nationally franchised shop which located in downtown with more than 20 designers were highly evaluated in view of service quality.

This study has the purpose to reveal the differences of residents' satisfaction level & demand of community environment and recognized residents' improvement priority of community environment at 3 complexes at the big city in the provinces. The 3 residential complexes had differentiated developmental concepts; the residence-oriented complex, the residence-government mixed complex with an eco-friendly concept, and the outskirt residence-industry mixed complex. Followings are the results of the study. 1) The satisfaction of residents in the community environment correlates with the increasing convenience facilities after construction. In the new outskirt complexes of smaller cities, dissatisfaction occurs more with public transportation rather than the road system, so that efficient public transportation systems, inner and neighboring areas, is requisite. 2) Even in the residence-oriented complex, the education environment does not entirely account for satisfaction level; the green environment is also second in priority after the education environment. In the residence-government mixed complex with an eco-friendly concept, a good natural environment does not entirely account for satisfaction level; education environment is also second in priority after the natural environment. The supply of sufficient schools may be fulfilled in the ways of reform of the education zone with neighboring existing residential areas. In the outskirt residence-industry mixed complex of smaller cities, priority was placed more on the location and convenience; this explains the complex's poor access to downtown.

본 연구는 부천시를 대상으로 지하수의 함양량, 대수층의 수리학적인 특성, 심도 및 지하수 심도에 따른 수리, 화학적 특성, 지하수의 오염특성을 파악하기 위해 수행되었다. 수리시험의 대상공은 부천지역의 토지이용형태와 도시발달을 고려하여 충적층 2개 지점과 암반층 9개 지점, 총 11개 지점을 선정하여 양수시험과 함께 회복시험을 동시에 실시하였다. 대수층의 투수량계수, 수리전도도 등의 수리상수를 도출하기 위해 양수시험은 충적층은 Theis의 해법에 의해 해석하였으며 암반층은 Theis의 회복해법에 의해 해석하였다. 학교운동장, 녹지공간이 확보된 공원 지역내 양수정은 지하수량이 다른 지역보다 풍부하고, 투수량계수와 수리전도도가 높은 값을 보였는테 이 지역이 강수의 수직침투와 수평이동이 활발하여 도시지역에서 주요 지하수 함양지역임을 뒷받침한다. 도심권의 도로 및 건축물에 의해 포장된 지역 양수정에서는 수리상수 값이 낮아 지하수의 함앙이 어려운 지역으로 관찰되었다. 부천지역 48개 지점에서 채수한 지하수는 심층기반암이 화성암에 기인하여 지하수가 약산성화된 특성을 보였다. 부천시의 지역별 전기전도도는 $70.4{\sim}1,287{\mu}S/cm$의 범위를 보였으며 용해성 광물이나 일부 탄산염의 영향을 받아 대부분의 지역에서 다소 높게 검출되었다.
