울산지역의 대수층 분포특성과 지하수 유동특성에 관해 연구하기 위해 크리깅 기법을 이용하였다. 울산지역의 시추자료 1,783개 지점과 지하수위자료 총 1,171개 지점에 대하여 2년간(2002년～2003) 자료를 획득하여 분석하였다. 본 연구지역의 표고 충적층 하부경계 심도, 충적층, 하부경계 심도, 충적층 층후, 풍화대 층후, 충적층-풍화대 층후, 대수층 단면, 지하수위 그리고 지하수유동 분석을 하기 위해 베리오그램 분석한 결과 풍화대 하부경계 심도에 지수형모델(exponential model), 나머지 지하수위를 포함한 성분들은 모두 구상형모델(shperical model)이 가장 적합하게 나타났다. 울산지역 대수층의 경우 산악지역은 얕은 충적층과 풍화대 분포가 나타나는 반면, 남구는 충적층, 북구는 풍화대 발달이 우세하게 나타났다. 그리고 울산지역의 충적층과 풍화대 층후 분포특성이 울산단층을 따라 층후가 두껍게 나타났다. 지하수 유동은 고지형의 북구와 동구 산악지역에서 바다에 인접한 내륙지역으로 지하수 유동특성을 보였으며, 울산의 4개구는 산악지역, 태화강, 동천강, 울산단층 그리고 충적층과 풍화대가 잘 발달된 대수층을 따라 지하수유동 특성이 잘 나타났다.

The genus Metopius is a relatively large ichneumonids group that includes 145 species worldwide. In this genus, 41 species have been reported from the Eastern Palaearctic region, while eight species have been reported from Korea. We reviewed Korean species of the genus Metopius and confirmed 13 species. We also report five species, Metopius (Ceratopius) maruyamensis Uchida, 1930, Metopius (Ceratopius) scrobiculatus Hartig, 1838, Metopius (Peltastes) fossulatus Uchida, 1933, Metopius (Peltastes) pinatorius $Brull{\acute{e}}$, 1846 and Metopius (Peltastes) sapporensis Uchida, 1930, which were recorded for the first time from Korea. A key to Korean species of the genus Metopius, redescriptions of newly recorded species and digital images of Korean Metopius are also provided.

This paper aims to analyze the changes of the population distribution of metropolitan area by the development of the new town-type innovative city, focusing on the case of the Daegu Innovative City. Using dataset in the survey of population trend and the migration statistics microdata provided by the Statistics Korea, we decomposed population changes of Daegu and surrounding regions into natural increase and social increases(net migration). As a result of the analysis, Dong-gu, where the Daegu Innovation City is located, experienced population growth due to its increase of net migration, whereas the total population in Daegu been decreasing continuously between 2007 and 2016. In particular, the occurrence of high net migration to Dong-gu in 2014 showed a pattern consistent with the completion of the Daegu Innovative City development and the relocation of government institutions from the Seoul metro area. As a result of analyzing the migration to Dong-gu, the population moved from the Seoul metro area was 6.9% of the total, while the population moving from the other 7 gu-gun areas in Daegu (35.8%) and the surrounding regions (8.2%) were significantly high. In particular, the migration to Dong-gu were from neighboring areas, such as Suseong-gu, Buk-gu and Gyeongsan-si. Therefore, the development of the new town-type innovative city could accelerate toward sprawling urban structure.

Previously, only one species belonging to the genus Apophua was recorded from South Korea by Kim (1955). Here, six additional species, A. cicatricosa, A. evanescens, A. honmai, A. stena, A. sugaharai and A. tobensis, are reported for the first time in South Korea. In this paper, we provide a key to the Eastern Palaearctic species of Apophua and diagnoses, as well as photographs of South Korean species.

The purpose of this study is to suggest a mid- to long-term expansion plan to resolve the blind spot and alleviate the imbalance of public library services in Daegu City. The research methods for this purpose included literature review, related laws and statistical data analysis, case study, and opinion survey. As a result, the first service area was set as a total of 14 areas based on administrative districts(Jung-gu, Seo-gu, Nam-gu, and Dalseong-gun each have one, Dong-gu and Buk-gu each have two, and Suseong-gu and Dalseo-gu have three each). Second, the expansion scenario for public libraries in Daegu City was proposed to add 26 libraries by the final target year (2032) based on the trend of national library growth over the past 13 years (2008-2020) and the forecast for the next 10 years (2023-2032). Third, the construction scenarios for each basic local government, excluding the Daegu representative library, are as follows: One library each in Jung-gu, Seo-gu, and Nam-gu; two libraries in Suseong-gu; three libraries in Dalseong-gun; four libraries in Dong-gu; and seven libraries each in Buk-gu and Dalseo-gu. In terms of floor area, it is proposed to add a total of 17 branch libraries with a minimum legal standard of 330-2,499㎡, four central libraries with 2,500-4,999㎡ each, and four central libraries with 5,000-9,999㎡ each. On the premise of these conditions, Daegu City and public libraries should focus on creating an inclusive and open community space, creating a digital platform, strengthening the library operation and cooperation system centered on Daegu representative library, developing collections and specializing services for local hub libraries, enhancing various knowledge information and program services, managing key library indicators and improving social contribution.

울산지역 수질특성에 관하여 연구하기 위해 228개 지점에서 수질성분 25개 항목을 분석하였다. 그 성분중 지하수 음용수 9개 수질성분(pH, EC, TDS, Cl, Mn, NO$_3$, SO$_4$, F, Fe)에 관해 수질분포특성 및 오염도를 나타내기 위해 모수적 통계기법인 정규크리깅과 비모수적 통계기법인 지시크리깅 기법을 적용하였다. OK와 IK의 성분별 베리오그램 분석한 결과 OK의 경우 모든 수질성분은 구상형모델(Spherical model)로 선정되었으며, IK의 경우 pH, TDS, SO$_4$, Cl, Mn, F, Fe 성분은 구상형모델로, EC는 지수형모델로, NO$_3$는 선형모델로 선정되었다. 그 결과 정규크리깅의 경우 연구지역의 수질특성을 정량적 분포특성이 잘 나타났다. 특히 태화강, 인접한 남구일원과 중구일원, 북구의 북서 일원 그리고 동구의 방어동일원에서 수질성분 9개 성분들이 다소 높게 나타났다. 특히 EC, TDS 그리고 Cl$^{-}$ NO$_3$ 성분이 높게 나타났다. 그리고 지시크리깅의 경우 정규크리깅과 비교하여 이상치가 크게 영향을 미칠 수 있는 통계학적인 오류를 보완하여 분석한 결과 울산지역 9개 성분 오염도는 EC>TDS>NO$_3$>pH>Fe>Mn>Cl>SO$_4$>F 순으로 오염특성이 나타났다.

The main results that can be drawn from the thematical analysis, based on 173 geographical names of Dong(洞) in Daegu city, are as follows. Firstly, the origin of the geographical name of Dong is divided into 10 groups such as natural landscape, human landscape, situation, and so on. Thematically, natural landscape is the most important factor among them. In particular, Dong-gu is such a case since Mt. Palgong and Geumho river are widely distributed around the area. Secondly, the origins of the geographical name of Dong in Jung-gu and Buk-gu are mainly concerned with human landscape and situation. Especially, Daegu-Eupseong(大邱邑城) has a great influence on the origin of the geographical name of Dong in Jung-gu. Thirdly, in 1914, the unification of administrative district established new Dongs(洞) and the geographical names of the new Dongs were made by borrowing each word from the existing geographical names of Dong. Fourthly, the geographical names of Dong in Suseong-gu and Dalseo-gu made after 1980s' were made in many cases by utilizing the existing natural landscapes. However, it is identified that Suseong field in Suseong-gu, Seongdang lake and Mt. waryong in Dalseo-gu have been recognized as the important natural landscapes. Lastly, the geographical name of Dong is commonly concerned with historical place names such as Gongsan battle in Dong-gu. It is judged that the geographical names of Dong based on Gongsan battle or a most intriguing piece of legend will make a great contribution on developing the regional tourism by storytelling.

Korean government annually estimates and reports the traffic safety index to evaluate the traffic safety of 228 Gu Gun. However, since the traffic safety index is derived from the spatially macroscopic perspective based on collected relative data, there are a couple of problems such as inability to investigate the individual traffic accidents on the spot, insecurity of accuracy and reliability of traffic safety index estimation method, and absence of establishing temporal relationship of traffic accidents. Thus, this study investigated temporal traffic safety in macroscopic manner for Gu Gun in Busan depending on the installation of the traffic safety facility (i.e., urban median), employing meta analysis. As a result, all Gu Gun in Busan except Saha, Buk, Dong, and Busanjin experienced more traffic accidents after installing the urban median, indicating that there are more rooms for improvement of macroscopic traffic safety evaluation.
