Appearance of carrion beetles by altitudes for 3 months from July to September 2011 was investigated in Dongyeopryeong course of Deogyusan National Park, Jeollabuk-do. The vegetation of the survey sites consist of four types, deciduous forest, mixed forest of deciduous and sasa types, and bushes. A total of 1,084 individuals in 6 species of carrion beetles by using bait traps were investigated and among them, Nicrophorus quadripunctatus was the most dominant species with 947 (87.36%). As a result of this survey, Nicrophorus quadripunctatus was appeared in all the altitudes but an alpine species, Silpha perforata was not appeared under 1,300 m altitude. Unlike Silpha perforata, no or few Calosilpha brunneicollis, Nicrophorus maculifrons, Nicrophorus concolor and Ptomascopus morio were appeared over 1,000 m. The analysis of vegetation preference by altitudes of survey areas shows no relevance between carrion beetles and vegetation except Silpha perforate which was appeared only in the bushes over 1,300m, but the more detail researches are required for preference of vegetation type.

본 연구는 우리나라 산림치유 프로그램의 현황을 파악하고 구성활동 내용을 분석함으로써, 향후 체계적인 산림치유 프로그램 운영방안을 위한 기초자료를 제공하는 것을 목적으로 수행하였다. 한국녹색문화재단에서 2008년부터 2010년까지 운영한 총 24개 프로그램을 수집하여 각각의 사례별로 대상, 내용, 구성 등을 1차 분석하고, 각각의 프로그램을 구성하는 활동 113개를 도출하여 영역, 목표, 주제, 활동장소, 실시주체 및 난이도 등 총 6가지의 기준에 따라 유형을 구분하였다. 그 결과, 산림치유 프로그램 구성활동은 주로 심리?정서적 안정을 치유 목표로 진행하는 사례가 많았으며, 산림치유 프로그램 대부분이 숲해설 활동을 포함하고 있는 것으로 분석되었다. 또, 산림치유 프로그램에는 강의 등 학습활동이 포함되는 사례가 많았으며, 혼자 할 수 있는 활동 보다 전문가가 개입하여 진행하는 활동이 많은 것으로 분석되었다. 다만 산림치유 프로그램 운영일정은 대부분 단순히 활동명만 제시되어 있거나 활동명과 함께 추상적이고 포괄적n치유의 목표가 제시되어 산림치유로서의 치유적 개입에 대한 내용이 명확하게 제시되어 있지 않은 것으로 파악되었다. 따라서 향후 산림치유 프로그램은 계획단계에서 참여자에 대한 뚜렷한 분석을 통해 맞춤형 산림치유 프로그램을 위한 구성활동을 도출해야 하며, 이를 위해서는 프로그램 및 구성활동에 대한 대상별 효과성 평가 연구를 통해 보다 전문성 높은 산림치유 프로그램을 개발하는 것이 필요할 것으로 판단된다. The aim of this study is to provide the basic data for the systematic forest healing programs of the future by analyzing the contents of the forest healing programs in Korea. The specific programs analyzed are the forest healing programs, operated by the Korea Forest Foundation, from the years 2008-2010. Twenty four programs were collected during the three years, each analyzing target, content and composition. These programs were then sorted into one hundred and thirteen activities of the forest healing program, which consists of six standards: Field, aim, subject, place, participation and level. As a result, it is apparent that firstly, the activities of the forest healing programs have many cases relating to proceeding programs for psychological and emotional stability. Secondly, the activities of the forest healing programs have many cases that included the forest interpretation activity and the learning activity, such as a lecture. Furthermore, it is fair to say that there are more activities involving expertise. It is important to state that the schedule of the forest healing programs mostly consisted of suggested activity names, often with an abstract and/or comprehensive concept; thus not offering contents about the intervention of the healing purpose. Therefore, in the design stage of the forest healing programs, we must state the activities of the composition for individualized forest healing programs, through clear analysis of participation. To achieve this, we must develop the systematic forest healing programs and formed activities, through study on verification of the effectiveness for the individual.

Scab disease caused by Venturia nashicola is of agroeconomic importance in cultivation of Asian pear. However, little is known about the degree of genetic diversity in the populations of this pathogen. In this study, we collected 55 isolates from pear scab lesions in 13 major cultivation areas in Korea and examined the diversity using sequences of internal transcribed spacer (ITS) region, b-tubulin (TUB2), and translation elongation factor-1a (TEF-1a) genes as molecular markers. Despite a low level of overall sequence variation, we found three distinctive subgroups from phylogenetic analysis of combined ITS, TUB2, and TEF-1a sequences. Among the three subgroups, subgroup 1 (60% of isolates collected) was predominant compared to subgroup 2 (23.6%) or subgroup 3 (16.4%) and was distributed throughout Korea. To understand the genetic diversity among the subgroups, RAPD analysis was performed. The isolates yielded highly diverse amplicon patterns and none of the defined subgroups within the dendrogram were supported by bootstrap values greater than 30%. Moreover, there is no significant correlation between the geographical distribution and the subgroups defined by molecular phylogeny. Our data suggest a low level of genetic diversification among the populations of V. nashicola in Korea.
Development of Carrot Medium Suitable for Conidia Production of Venturia nashicola
Choi, Eu Ddeum,Kim, Gyoung Hee,Lee, Young Sun,Jung, Jae Sung,Song, Jang Hoon,Koh, Young Jin The Korean Society of Plant Pathology 2017 Plant Pathology Journal Vol.33 No.1
The causal fungus of pear scab, Venturia nashicola, grows slowly and rarely produces conidia on artificial media in the laboratory, but it produced conidia on the Cheongah medium containing Cheongah powder. V. nashicola grew too slow to produce conidia until 15 days after cultivation but produced conidia with $4{\time}10^4$ conidia/plate 30 days after cultivation on the Cheongah medium containing 1% Cheongah powder. V. nashicola showed a peak production of conidia with $4.5{\times}10^5$ conidia/plate 60 days after cultivation on the carrot medium containing 2% carrot powder, one of the constituents of Cheongah powder. The carrot medium is considered to be the best medium to obtain conidia of V. nashicola in the laboratory until now. This is the first report on the development of a suitable medium for conidia production of V. nashicola, as far as we know.

본 연구의 목적은 서울지역에 거주하는 자력형 대학생의 주거ㆍ경제생활실태 및 주거환경 만족도를 경제적 부담 스트레스 수준과 거주주택 유형별로 비교분석하는 것이다. 본 연구는 설문을 이용한 일대일 면접조사로 진행하였다. 조사대상은 지역과 지역 내 장소를 선정하는 2단계의 군집표본추출을 통해 선정한 만18세에서 34세 미만의 자력형 대학생 199명이었다. 조사내용은 자력형 대학생의 주거환경 특성, 경제생활 특성, 주거환경 만족도, 현 거주주택 불편사항이었으며, 수집된 자료는 SPSS 통계패키지를 활용하여 분석하였다. 조사결과, 임대료 마련 스트레스 수준이 높은 경우 주거ㆍ경제 생활 실태가 전반적으로 취약하였고 주거환경 만족도는 대부분의 항목에서 상대적으로 낮았으며 그 차이는 3가지 유형으로 분류되었다. 거주주택 유형별 주거ㆍ경제생활 실태는 큰 차이를 보이지 않았으나 주거환경 만족도는 차이를 보였으며 그 차이는 6가지 유형으로 분류되었다. 대개 고시원에 거주하는 대학생의 만족도가 가장 낮았으며 오피스텔 거주 대학생이 만족도가 가장 높았다. 본 연구는 자력형 대학생을 위한 주거복지 대책에 함축적인 의미를 던지고 있다. This study aimed to examine and compare housing conditions and satisfaction degree of working college students in Seoul metropolitan area, depending on their stress level from economic burden and living housing type. The interview using the questionnaire was conducted. The subjects were 199 working college students aged between 19 and 35. The two-tier cluster sampling method were used, the region and representative university within the region. The comparison of satisfaction degree per type of housing of working college students has been conducted to find 3 characteristic patterns of satisfaction degree per housing condition from the stress of preparing the fund for rent, and students with high degree of stress from arranging rent showed relatively low degree of satisfaction in most items. 6 patterns have been identified in terms of housing types, and most of the students living in the Gosiwon, the poorest condition and housing type, showed the lowest degree of satisfaction, while those residing in the officetel turned out to the most satisfied. This study gives implications of housing welfare for working college students.
