본 연구는 국내 하천에서 방치되고 있는 구하도 구간의 물리적 상태를 파악함으로써 이를 보전 또는 관리하기위한 기초자료로써 활용하고자 한다. 국내의 구하도 구간은 자연적인 발생보다는 하천의 직강화, 하천부지 이용의 고도화 등 인위적인 교란으로 인해 형성된 것이 대부분이다. 이와 같이 사행구간의 하도가 절단(Cutoff)됨으로써 형성된 구하도는 우각호 형상의 습지형 구하도와 이미 육역화되어 농경지나 나대지로 이용되는 육화형 구하도로 구분할 수 있다. 특히 폐천(Abandoned Channel)화가 진행된 대부분의 습지형 구하도는 수질, 생태계, 육역화, 농업용수 이용 등 다양한 문제점 및 현안을 가지고 있기 때문에 이에 대한 보전 또는 관리가 필요하다. 이를 위해서는 우선적으로 습지형 구하도의 현재를 진단하고 평가하기 위한 연구가 선행되어야 한다. 따라서 본 연구에서는 습지형 구하도를 평가하기 위한 평가지표를 제안하고 이를 만경강 습지형 구하도 5개소에 적용하였다. 평가지표는 국내외에서 제안된 하천환경 평가지표와 RAM(일반기능평가기법)을 토대로 작성하였다. 이 평가지표는 단절된 습지구간에 적정한 지표, 자료 획득의 용이성, 즉시 적용 가능한 것을 우선순위로 선정하였다. 평가지표는 자연도, 서식처, 친수, 수질 등 4개 지표를 세분화한 총 25개 항목으로 제안하였다. 만경강에 대한 물리적 평가결과 습지형 구하도의 경우 서식처, 자연도 부분이 높은 점수를 획득한 반면 수질과 친수 지표는 상대적으로 취약한 것으로 평가 되었다. 이와 같은 결과는 향후 만경강 습지형 구하도에 대한 보전 및 관리계획을 수립함에 있어 주요 고려사항이 될 수 있을 것이다.

The demand for National Woodland Burial Grounds is expected to increase as interest in natural burial, including woodland burial, is increasing. This study was performed to provide evaluation criteria applying weighting factors to the evaluation for location selection. Through literature review, location selection evaluation factors for forest facilities, similar to forest welfare facilities, were reviewed and analyzed. As a result of the analysis, 74 preliminary evaluation criteria were selected. Based on the results, three expert groups (public servants in central and local governments and other public agencies in charge of forest welfare facility, related field researchers, and civil experts) reviewed the preliminary evaluation factors. Evaluation factors were classified into two categories, 6 sub-categories, and 22 segments. The selected evaluation factors were layered for the second preference survey. They were classified into Forest Environment and Human Environment, and those categories were further classified into three categories. Then they were further classified into segments. After segmentation, the experts who participated in the first survey checked the differences in the significance of the layered factors by utilizing AHP. The site evaluation criteria table was prepared using the evaluation criteria and the significance of each layer. In order to apply it to the candidate sites, 10 sites including the existing National Woodland Burial Grounds and 9 candidate sites considered in the previous studies were compared and analyzed including Ulju County Ulsan City, Suncheon City Jeollanam-do and Janggun-myeon Sejeong City.

The Korean polysemic ending '-(eu)lgeol' can has two different meanings, 'guess' and 'regret'. These are expressed by different boundary-tone types: a rising tone for guess, a falling one for regret. Therefore the sentence-final boundary-tone type is the most salient prosodic feature. However, besides tone type, the pitch difference between the final and penultimate syllables of '-(eu)lgeol' can also affect semantic discrimination. To investigate this aspect, we conducted a perception test using two sentences that were morphologically and syntactically identical. These two sentences were spoken using different boundary-tone types by a Korean native speaker. From these two sentences, the experimental stimuli were generated by artificially raising or lowering the pitch of the boundary syllable by 1Qt while fixing the pitch of the penultimate syllable and boundary-tone type. Thirty Korean native speakers participated in three levels of perceptual test, in which they were asked to mark whether the experimental sentences they listened to were perceived as guess or regret. The results revealed that regardless of boundary-tone types, the larger the pitch difference between the final and penultimate syllable in the positive direction, the more likely it is perceived as guess, and the smaller the pitch difference in the negative direction, the more likely it is perceived as regret.

The value of platform companies is rapidly increasing, exerting significant influence across industries. Identifying and fostering promising platform companies is crucial for enhancing national competitiveness. Consequently, tailored evaluation standards are necessary for such companies. This study derived investment decision factors specific to platform companies and compared the importance of each factor using Analytic Hierarchy Process (AHP) analysis. Key factors included platform characteristics, finance, entrepreneur (team), market, and product/service attributes. The findings revealed that platform characteristics were deemed the most crucial factor for investors. Specifically, factors such as platform size, ease of value fixation, core participant group, and data value were identified as pertinent for evaluating platform companies. Moreover, analysis distinguished between investors with prior platform investment experience and those without. Significantly, investors with platform investment experience placed greater emphasis on the value of data secured by platform Furthermore, it was observed that investors prioritized future value and growth potential over current value when investing in platform. Notably, founder/team characteristics, typically highly regarded in previous studies, ranked lower in importance in this study, highlighting a shift in focus. The discrepancy between this study's results and prior research on investment decision factors is attributed to the specificity of the questions posed. By focusing on investment decision factors for platform startups rather than generic startup inquiries, investor responses aligned more closely with platform-focused considerations. Given the burgeoning venture investment landscape, there's a growing need for detailed research on startups within specific sectors like IT, travel, and biotech. This approach can replace extensive research covering all startup types to identify investment decision factors suited to the characteristics of each individual industry.

National and local governmental adaptation plan for climate change will become mandatory in 2015. In order to establish the plan, assessment of vulnerability to climate change needs to be preceded. LCCGIS, a toolkit for vulnerability assessment, has been widely used by many local governments. However, assessment results by LCCGIS are not yet reliable because most of the vulnerability indices applied to LCCGIS　have the same value for almost all administrative units in Korea. In this study, proxy variables for hard-collectable indices were introduced, and the results were compared with those without any proxy variables. Vulnerability assessment could be conducted subjectively due to uncertainty. Thus, determination of objective indices, understanding the available data, and changes of indices in local conditions were organized. Results from this study are expected to make vulnerability assessment reliable and contribute to assessing vulnerability to climate change reflecting on local governmental characteristics.

오늘날 수자원 관리의 중요성과 관심이 매우 커지는 가운데 신뢰도 높은 수문자료의 생산은 매우 중요하다. 나아가 기후변화에 따른 집중호우 등을 고려했을 때 효율적인 수문자료 확보를 위해 수문관측소에 대한 객관적인 평가지표와 지점 중요도, 현장에서의 측정 및 하천환경 변화 등의 다양한 검토가 선행되어야 한다. 본 논문에서는 환경부 2019년 낙동강 수계 측정지점을 대상으로 관측소의 객관적인 평가지표, 즉 관측소 설치목적에 따른 지점 중요도(하천 대표 유역, 홍수 및 갈수 예 경보, 유지유량, 갈수모니터링 등)를 고려한 관측소 평가를 실시하였다. 아울러 각 지점에 대한 측정경험과 하천환경 변화에 대한 모니터링 자료를 바탕으로 측정 지점의 난이도와 관측소 변화 여부에 대한 평가 항목을 7가지로 분류, 평가하였다. 단순히 현장경험과 실용성에 중점을 둔 평가항목은 다소 주관적인 판단이 들어갈 수 있기 때문에 의사 결정 과정에서 데이터에 대한 가중치를 부여할 수 있는 엔트로피 기법을 적용하여 관측소 평가결과에 반영하였다. 그 결과 관측소 중요도가 높은 필수 지점 뿐 만 아니라 현장 여건이 고려되지 못한 지점들, 지점 특성에 따라 이설 및 관측망 조정이 필요한 지점도 다소 존재하였다. 효율적인 측정지점 선정을 위해서 관측소의 설치목적 뿐 만 아니라 설계홍수량이나 하천설계기준 수립 등의 객관적인 평가지표와 하천환경 변화 나아가 경제성 검토 등 다양한 요소의 추가적인 연구가 필요하다고 판단된다.
