Geological heritages can be defined conveniently as geological records worthy of conservation, and are represented in most cases by geological outcrops. So survey and evaluation of geologic outcrops are necessary for better conservation of geological heritages. As a measure to prevent potential destruction of geological heritages from various development projects, I propose construction of database based on survey and evaluation forms of geological outcrop, which can also be used for environmental impact assessment. The geological survey form consists of survey area, category, subcategory, location, dimension, geologic features, photo, description, and investigator. The evaluation form consists of evaluation category, detailed evaluation, comprehensive evaluation, and evaluation grade. The evaluation category is divided into academic aspect, education effect and landscape. The detailed evaluation items for academic aspects and education effect are representativeness, rarity, diversity and typicality, while those for geomorphology and landscape are peculiarity, aesthetics and naturalness. The evaluation grades are divided into five, where the first grade means a must of conservation.

The purpose of this study is to examine factors influencing social relations in elderly people participating in the Senior Employment Project and explore ways to improve their life quality by promoting the enhancing social relations in old age based on that. To attain the study goal, this researcher conducted hierarchical multiple regression analysis on 272 elderly persons having experience to participate a senior employment project selected through random sampling. According to the findings, elderly people's internal factors, self-esteem and external factor, job satisfaction, influence social relations in elderly people participating in the Senior Employment Project significantly. In other words, if elderly people participating in the Senior Employment Project have higher self-esteem, and job satisfaction, their social relations are better. Based on the results, this author provides political suggestions as follows: first, it is needed to develop policies and programs that can enhance elderly people's self-esteem. Second, it is necessary to acknowledge their worker's status, diversify business types and areas for them, and improve their labor conditions so that elderly people can show higher job satisfaction. Third, it is needed to develop both official and non-official support systems and build networks to form new social relations.

2017년 12월 기준 우리나라에 등록된 자동차는 약 2,200만 이상으로, 그 증가율은 매년 증가하는 추세이다. 이러한 최근 차량대수 및 고자산인 외산차 보유율 증가는 자연재난에서 노출과 관련한 위험도를 증가시키는 주요인이 되며, 홍수발생 시 상당한 규모의 경제적 피해를 야기한다. 현재 국가연구개발사업으로 진행 중인 행정안전부(2017) 연구는 위험지역 내 차량의 공간적 분포와 차량유형별 침수심에 따른 취약성을 고려하여 어떠한 홍수사상으로부터 예상되는 차량 피해액을 추정하는 방법을 제시한 바 있다. 여기서는 어떠한 집계구 내에서 동일한 침수심 구간을 가지는 면(polygon)을 분석단위로 하고 있는 데, 이를 편의성 차원에서 벡터자료에 기반 한 연산과정을 수행할 경우 정의된 침수구역도(재해정보)의 고유 정보가 훼손되거나, 세분화된 침수심 구간에 따른 손상률 관계를 사용할 수 없는 문제점이 있다. 이에 본 연구에서는 격자 기반의 침수구역도와 인벤토리 지도로부터 Raster GIS 공간연산을 활용한 차량피해 산정절차를 제시하였고, 이를 신천수계 하천기본계획(경기도, 2011)에서 계획된 치수사업에 적용하여 홍수빈도별 사업시행 전후 상황에 적용하였다. 이 과정에서 침수구역도는 인벤토리 상의 집계구 면적을 고려하여 $5m{\times}5m$ 크기로 제작하였고, 동일한 격자크기로 변환된 인벤토리는 변환 전후 면적을 기준으로 할 때 거의 오차가 없는 것으로 확인되었다. 그리고 Raster 공간연산으로부터 침수편입률을 결정하는 과정에서 집계구 넘버 및 침수심 정보를 확인하기 위한 자료별 전처리 과정을 제시하였고, 여기서 집계구 넘버는 인벤토리 정보와 침수심 정보는 손상함수와 연계된다. 본 연구에서 제시한 결과는 향후 실무에서 직접 적용하는 데 활용하기 위하여 방법론과 함께 가이드라인 문서로 정리할 계획이다.

하천환경 복원사업이나 자연형하천 정비사업의 근본 목표는 그 하천 고유의 하천경관이나 생태계 등 특성을 회복(Rehabilitation)시키거나 복원(Restoration)하는 것이다. 현재 이 치수기능 확보를 위한 댐 보의 건설, 하천정비 및 골재채취 등 하천의 인공화가 계속되고 있으며, 이에 따른 하천 및 하도의 물리, 화학, 생물에 미치는 영향은 심각한 수준이다. 이러한 하천의 인위적 교란은 요인, 규모, 빈도 및 강도는 다르지만 하천생태 서식처의 물리적, 화학적 특성이 변형, 변질되어 하천생태계가 변화, 단절, 절멸되는 심각한 상태가 빈발하고 있다. 하천교란(River disturbance)은 요인에 따라 유량 및 유사량 변화, 하상변동, 하도준설, 인공호안, 생태통로 차단 등 하천의 물리적 환경 변화를 초래하고, 그에 따른 영향으로 생물종의 감소 및 단순화, 개체수 감소 등과 같이 하천 생태계가 변화하게 된다. 그러나 하천의 교란평가에 대한 연구가 미흡하고, 또한 표준화된 평가체제가 구축되어 있지 않을 뿐 만 아니라 하천환경의 복원에 대한 의식 보급도 부족한 것이 현실이다. 따라서, 본 연구에서는 하천의 교란정도를 파악하기 위한 하천교란평가기법 개발을 위한 전단계로서 일본의 하천수변 국세조사, 영국의 River Habitat Survey, 호주의 River Assessment System, 미국의 Stream Corridor Restoration 등에서 제시하는 하천모니터링 및 평가체제를 비교, 분석하였다. 외국사례 분석 결과를 토대로 하천교란 요인을 하천정비, 댐건설, 골재채취로 유형화하고 교란요인별 조사해야 할 물리적 인자로서 유량, 유사량, 하도 제원, 특징적 내용, 하도형상, 여울과 소, 점사주, 인공구조물, 제방 호안의 재료 및 특징 등으로 선정, 검토하였으며, 생태계 인자로서는 제방 마루의 토지이용 및 식생구조, 하도의 식생유형, 하도주변 토지이용, 하안(bank) 형상 및 구조, 수종 및 구조, 하도 및 하안 특징 및 구조 등으로 선정, 검토하였다. 이상의 하천교란과 관계되는 지표를 선정하여 물리적, 생태적 조사 및 교란평가기법(안)을 개발, 제시하였다.

It is needed to transfer the technology actively which has already developed to improve a up-to-date technology and foster the technological innovation. The technology transfer also can bring about a commercial success. To promote the technology transfer, it is needed to develop a new technology valuation model for a specific technology from a objective point of view, as well as to equip an institution such as the technology transfer center. The technology valuation from a objective point of view is of importance as the basic information for the price negotiation between a technology-buyer and a technology-seller. This paper takes aim at investigating a new technology valuation model and developing a technology valuation system for promoting the technology transfer. A new technology valuation system is developed as a web-enabling base. Using this users are able to estimate the value of specific technology on a real time efficiently.

This paper evaluates precipitation forecast skill of Global/Regional Integrated Model system (GRIMs) over South Korea in a boreal winter from December 2013 to February 2014. Three types of precipitation are classified based on development mechanism: 1) convection type (C type), 2) low pressure type (L type), and 3) orographic type (O type), in which their frequencies are 44.4%, 25.0%, and 30.6%, respectively. It appears that the model significantly overestimates precipitation occurrence (0.1 mm d^-1) for all types of winter precipitation. Objective measured skill scores of GRIMs are comparably high for L type and O type. Except for precipitation occurrence, the model shows high predictability for L type precipitation with the most unbiased prediction. It is noted that Equitable Threat Score (ETS) is inappropriate for measuring rare events due to its high dependency on the sample size, as in the case of Critical Success Index as well. The Symmetric Extreme Dependency Score (SEDS) demonstrates less sensitivity on the number of samples. Thus, SEDS is used for the evaluation of prediction skill to supplement the limit of ETS. The evaluation via SEDS shows that the prediction skill score for L type is the highest in the range of 5.0, 10.0 mm d^-1 and the score for O type is the highest in the range of 1.0, 20.0 mm d^-1. C type has the lowest scores in overall range. The difference in precipitation forecast skill by precipitation type can be explained by the spatial distribution and intensity of precipitation in each representative case.
