  • As United Nation (UN) declared 2010 to be the International Year of Biodiversity, the biodiversity issue has gained much attention since the issue of climate changes. Also, related researches for protecting and conserving the biodiversity are accompanied in the world. In this study, National Ecology Information is obtained from Ministry of Environment and Korea Forest Service and is utilized to valuate biodiversity and ecosystem services in Pyeongchang, Kangwon-do in Korea. For this, they are categorized into direct- or indirect-use value and nonuse value. Research results show that the biodiversity and ecosystem services in Pyeongchang are assessed as 2 trillion and 460 billion won. From this research, we evaluate the economic value of biodiversity and ecosystem services, and also suggest the possibility to utilize them as basic information for a decision making to establish the biodiversity protection plan.

  • The purpose of this study was to examine the difference of the father's and mother's reactions to their children's negative emotions, relations among the children's variables, parent's variables, and parent's reactions. The subjects selected were 183 mothers and 183 fathers with children aged three to five-years-old, from a childcare center and kindergarten in Kwang-ju. Parental emotion-related practices regarding children's negative emotions were assessed with an adaptation of the CCNES(Fabes et al, 1990) that was modified by Kim Hee-Jung(1994). Descriptives, Pearson's correlation coefficient, were used for data analysis by using the SPSS 15.0 program. The results of this study can be summarized as follows: First, fathers and mothers used more positive reactions than negative reactions when their children showed negative emotions. The mothers were significantly higher than fathers on encouragement of expression, punitive, and distress reactions. Second, the children's age and gender, parent's age, level of education and income were negatively and positively correlated to the father's and mother's reactions to their children's negative emotions.

  • The purpose of this study is to analyze college students' TV advertising information recognition, comprehension and affecting factors on them. Data were collected by a survey of college student consumers after experiments with TV commercials. ANOVA, Duncan, and stepwise multiple regression analysis were carried out with the gathered data. The results are as follows. First, the TV advertising information comprehension degree of the college students consumers were shown to be low, by 41.2%. The comprehension degree was especially low when the information was presented visually without any verbal expression. Second, assuming that the comprehension of TV advertisements is defined by a correct perceptual understanding after recognizing the consumer-deception factors, the percentage of correct answers was poor, by 29.2%. Third, according to sex, average monthly income, degree of immersion on TV commercials, advertisement attitude, and consumer education of school, the TV advertisement information recognition and comprehension showed varying degrees between the groups. In the case of women students whose average monthly income was 100 to 300 thousand Korean won, had a high degree of immersion on TV commercials, and a high degree of consumer education at school, the TV advertising information recognition was shown to be high. In the case of third year college students who had a medium level of immersion on TV commercials and a high degree of consumer education at school, the TV advertisement comprehension was high. Fourth, the high explanatory factor of TV advertising information recognition and comprehension was found to be common because of consumer education at school.

  • We analyzed the preliminary survey data (2014-2016) of macrobenthic community biomass (n = 112) from the wind farm area located in the southern part of the west coast of Korea and compared this data with data from the entire west coast (n = 369; 2006-2008). Modal classes from frequency distributions were 6 times higher in the latter (5 vs. 32 g/㎡). The mean and median values of the latter were 1.3 and 1.7 times higher (mean, 20.7 vs. 27.8 g/㎡; median, 17.1 vs. 29.5 g/㎡), and the maximum value was 3.4 times higher. Mood's median test showed significant difference at p-value = 0.01. We estimated the biomass-to-depth relationships from each data set by using Akaike Information Criterion and regarded the non-overlap of the 95% confidence intervals as indicating significant difference. The biomass was different from a 10 m depth below, and 3 times higher in the west coast at around 20 m compared with the maximum depth of the wind farm area. A local event of catastrophic sedimentation ranging from 1 to 2 m was observed in the wind farm during winter surveys. This could be a probable source of the lower biomass, but information on biomass seasonality and a natural experimental approach seem to be needed for the conduct of further studies. This study is meaningful in that it provided the background to assess future changes by understanding the lower level of benthic productivity in the area. We expect this study will contribute to the preparation of measures that can remove or mitigate the source of the lower biomass and improve the productivity of fishery resources in the area.

  • 최근 부각되고 있는 도시지역의 환경문제 해결을 위해서는 다각적인 접근방법이 요구되는데, 도시지역에 산재해 있는 도시숲의 효율적 조성 및 관리는 그 방법 중 하나가 될 수 있다. 이에 본 연구에서는 도시숲의 경관생태학적 관리를 위한 평가지표를 설정하고, 대전광역시와 울산광역시 시가지에 분포하는 도시녹지를 대상으로 생물서식공간으로서의 비오톱 유형을 구분하였으며, 그 기능적 특성에 기초한 등급과 식생경관의 구성적 특성을 평가하였다. 평가지표 및 방법은 국내의 연구사례가 드물어 유럽에서 사용되고 있는 지표를 국내 실정에 맞게 수정 보완하였으며, 최종 결과는 합산평가 매트릭스법을 사용하여 분석하였다. 분석결과, 비오톱 유형은 기존 문헌의 조사결과와는 달리 면적이 다양성에 미치는 영향은 적은 것으로 분석되었으며, 중점 비오톱 등급은 공원의 면적 차이와 성립위치 및 인위적 간섭정도의 차이로 인해 남선공원과 함월산은 3등급, 보문산과 염포산은 4등급으로 나타났다. 생물서식공간으로서의 비오톱 기능평가 등급을 분석한 결과, 지역에 관계없이 3~5등급 즉 보통 이하로 나타나, 서식공간의 제공이라는 기능적 역할은 상대적으로 낮게 나타난 것으로 분석되었다.

  • 최근 코로나 엔데믹(Endemic)을 배경으로 메타버스의 미래에 대한 회의론이 부상하는 한편, 로블록스(Roblox) 등 주요 메타버스 플랫폼이 생성형 AI를 결합한 서비스를 출시하고 애플(Apple)의 MR(Mixed Reality)하드웨어인 비전프로(Vision Pro)가 발표되면서 메타버스의 새로운 기대감이 형성되고 있다. 이처럼 메타버스의 전망이 엇갈리는 상황에서 메타버스를 생태계적 관점에서 파악하고, 주요 생태계적 특징과 발전 동력 그리고 향후 발전 가능성을 검토하는 것이 필요하다. 이에 본 연구는 정보시스템(IS)분야에서 생태계 연구를 대표하는 Wang(2021)의 IET(Information Ecology Theory)를 사용하여 메타버스 산업 생태계(MIE : Metaverse Industrial Ecosystem)를 도출하였다. 분석 결과 MIE는 네 가지 세부 영역(Tech Landscape, Category Ecosystem, Metaverse Platform, Product/Service Ecosystem)으로 구성되며, 디지털 연결성, 현실과 가상의 연결, 가치 창출, 가치 공유(Web 3.0) 라는 특징을 확인하였다. 또한 MIE의 세부 영역 간 상호작용과 상술한 특징들은 메타버스를 플랫폼을 넘어 생태계 차원에서 발전시키는 동력으로 작용하고 있음을 알 수 있었다. 생태계 차원에서의 MIE의 발전은 크게 세 가지 단계(Narrow Ecosystem, Expanded Ecosystem, Everywhere Ecosystem)로 정의되었으며, 향후 로봇, AI, 6G 등 유관 기술과 산업의 발전은 현(Expanded Ecosystem) 생태계 수준을 넘어 현실과 가상이 연결되는 Everywhere Ecosystem으로의 발전을 촉진시킬 전망이다. 본 연구는 다음과 같은 시사점을 내포한다. 기존 메타버스 연구에서 취약했던 생태계 분야에 있어 핵심 이론과 분석 기반을 제공, 다양한 메타버스 연구 주제를 제시한다. 또한 메타버스 연구의 주요 분야인 메타버스 개념 연구와 영향력 연구를 통합할 수 있는 학술적 기반을 제공한다. 마지막으로 본 연구가 제시하는 메타버스의 발전 단계와 발전 조건 등을 참고하여 기업과 정부는 미래 메타버스 신시장 및 관련 기술을 발굴하고, 다양한 메타버스 사업 전략을 검토할 수 있을 것으로 기대된다.

  • The aim of the present study was to assess the anti-obesity effects of fermented kochujang supplement in C57BL/6J mice. Thirty mice were divided into 3 groups; normal diet control group (ND), high fat diet control group (HD), and high fat diet plus kochujang supplemented group (HDK). Results were as follows: 1. Fennented kochujang supplement in high fat diet decreased body weight and epidydimal and back fat weight compared to non-supplement in HD group. 2. Lipid content and blood glucose level were lower in HDK group than HD group. 3. Fermented kochujang supplement increased mRNA level of lipolytic genes such as acyl-CoA synthetase (ACS), carnitine palmitoyltransferase-1 (CPT-1), and uncoupling proteins-1 (UCP-1) expression, whereas decreased mRNA level of adipogenic genes such as acetyl CoA carboxylase (ACC) expression. These findings suggest that fermented kochujang supplement in high fat diet normalized body weight, epididymal and back fat weight, lipid content, and blood glucose levels through controlling lipid metabolism and provides basic information on the control of obesity.

  • We report the status of wetland vascular plant species in Korea including the whole peninsula and its adjacent islands. This analysis was based on database from our previous categorized list. In all, 4,050 taxa have been reported, including 3,769 native and 281 naturalized. Of these, 479 taxa (12%) are considered as wetland vascular indicator species: 240 obligate wetland plants (OBW) and 239 facultative upland plants (FACW). Approximately 31% of those 479 taxa, i.e., 149 taxa, are labelled as aquatic macrophytes. Wetland plants, mostly herbaceous but some woody, inhabit aquatic bodies and wet meadows. Except for two OBW and six FACW taxa, the rest of the plants are summer-green only. The information provided here is valuable for making assessments of wetland ecosystem health, as well as for developing management plans to preserve and restore wetlands and their resident plant species while also creating artificial wetland environments.

  • The purpose of this study was to examine the financial status of the small business households, and to analyze their investment behaviors according to socio-economic variables like age, income, education, job satisfaction, and region. The size of total sample was 2167 with basis of data analysis of Korean Household Panel Study from Daewoo Economic Research Center. Descriptive Statistics were used to analyze their financial status according to the socio-economic variables. The results showed that small business family's financial status was differentiated according to age, income, job satisfaction, and region. Households' investment on the primary financial institute such as bank was differentiated by income, level of education, and job satisfaction. The amount of investment on secondary financial institute such as mutual fund was differentiated by income, age, and region. The households' investment for insurance was affected by all socio-economic variables except region and not significantly different according to socio-economic variables for stock and bonds. The amount of net-asset for households was affected by the level of education, age, and income and the amount of debt most by age and income. The results of this study was useful to develop the estimation tool for the small business households credit and also provides the basic informations for the financial assistance of those households.
