Japan enacted the "Designated Radioactive Waste Final Disposal Act" for the geological disposal of high-level radioactive waste in 2000 and began the site selection process. However, no local government wanted to participate in the siting process. Therefore, in 2015, the Japanese government developed a new site selection process during the literature survey step, and on June 28, 2017 they published a "Nationwide Map of Scientific Features for Geological Disposal" created with the aim of promoting public participation from local governments. This map illustrated the requirements and criteria to be considered in the early or conceptual stages of securing a geological repository and was useful for improving public understanding and exchanging opinions with local governments by analyzing the suitability of different geological disposal sites.

To understand the present states of abstracting and to investigate contents of abstracts, a survey content analysis was done in the field sciences. Of the 102 nation wide scholarly journals examined $54(53\%)$ included abstracts with articles. 33 had abstracts in Korea Among the 34 journals with editorial statements about abstracting only 13 had suggestions about abstract contents. Based on the investigation, 4 disciplines having abstracts mostly was selected and 149 abstracts in the 4 major journals in each discipline were sampled. Complete abstracts were ama;uzed according to 12 variables covering required content elements, unnecessary statements, and writing styles. Statistical characteristics of the abstracts is varied among disciplines and the scope is very wide. Particularly number of paragraph and number of character per abstract is much different from the standards. The content analysis showed $51\%$ of the abstracts were incomplete. $39\%$ of the abstracts did not mention research method used. 59 abstracts included unnecessary statements. Writing stle analysis also showed many faults both in the pronoun abuse and the misuse of voice or tense. Korean author abstracts in social science scholarly journals have deficiencies in linguistic structures as well as in contents and style.

기존 저수지 농업용수는 주로 논의 벼재배 용수공급을 목적으로 설계되었지만, 논 지역 타작물 재배 지원 등의 정책으로 논에서 밭으로 전작화가 증가함에 따라 농업용수의 효율적 분배를 위한 논의 전작화 패턴 분석이 필요한 실정이다. 이에 본 연구에서는 공공데이터 포털의 2019년 팜맵을 활용하여 최신 경지 현황을 파악하고, 환경부의 2007년, 2019년 토지피복지도를 이용하여 전작화 패턴을 분석하였다. 구축된 팜맵과 토지피복지도는 환경부 토지피복분류 기준 농업지역 중분류로 일치시켜 분석에 활용되었다. 논, 밭, 시설재배지 등의 농경지 이용 현황 및 전작화 추이는 전국 단위, 권역 단위로 분석되었고, 주요 시도와의 공간적 거리를 전작화 영향인자로 설정하여 DUP(Degree of Urban Proximity) 등의 지표로 그 영향을 확인하였다. 또한, 전체 경지 중 논, 밭의 면적과 증감 추이를 ACR(Area Change Rate) 등의 지표로 전작화 규모를 파악하였고, LPI(Largest Patch Index), LSI(Landscape Shape Index) 등의 지표로 개별/집단화 전작의 패턴분석을 수행하였다. 본 연구로 제시된 저수지 수혜 구역별 논의 전작화 패턴은 논 벼재배와 농업용수 수요 특성이 상이한 밭작물에 안정적 용수공급 체계 구축 등의 기초자료로 활용 가능할 것으로 생각된다.

현재 지역산업진흥계획이 수립되기까지 수도권 억제와 지역경제 활성화를 위한 다양한 정책 및 법령들이 수립${\sim}$제정되어 왔으나, 그 성과는 미흡하였고, 첨단산업과 지역의 발전을 함께 추구한 과학기술 집적지 조성정책도 연구기관과 산업체간의 기술개발에 대한 수급의 불일치, 지역별 특성화와 차별화 미흡, 사업간 연계성 부족 등으로 성과는 미약하였다. 중앙 부처에서 다양한 지역산업 관련 기술개발 지원사업도 전개해 왔으나, 부처별로 독자적으로 사업을 추진하여, 정책 상호간의 연계성이 부족하고 투자 효율성이 저조하여, 산업자원부에서 산업발전법에 근거하여 2002년 '지역산업진흥계획'을 수립하였다. 이 계획은 지역별 전략산업을 중심으로 한 지역혁신체제 구축에 초점을 두고 있으며, 지역의 내생적 성장을 위한 네트워크 형성, 투입요소 증대에서 지역 산업경쟁력 강화로의 전환, 중앙정부와 지자체의 공동 계획입안 등에서 기존의 정책들과 차이를 보인다. 지역산업정책의 최종목표는 '지역균형발전'이며, 중간목표는 '지역산업의 활성화'라고 할 수 있다. '지역산업의 활성화'를 위한 기본전략으로 '3개 권역별 전략산업 집중 육성'과 '제도적 기반 구축'을 제시하고 있다. 이러한 기본전략은 매우 포괄적이어서 정책수단으로 보기에는 무리가 있다. 따라서 이러한 기본전략 하에 추진하고자하는 사업들을 검토하고 평가의 목적에 맞게 유형화함으로써 동지역균형발전과 지역경쟁력의 강화이며, 그 기본전략으로는 지자체의 역할제고를 바탕으로 한 전략산업 중심의 지역혁신체제(Regional Innovation System : RIS) 구축을 제안하고 있다. 지역 내에서는 각 조직 간의 역할분담이나 연계가 이루어지지 않아 인력과 재원 및 특정분야에 대한 중복투자 문제가 지적되고 있으며 각각 소규모여서 규모의 경제효과를 꾀할 수 없고 경제적 효과가 가시화되는 데에는 오랜 시일이 걸리고 있고, 지역의 산업발전을 체계적으로 기획하고 지역내 다양한 이해관계를 조정하는 총괄 추진기구가 없어 효율적인 지역산업육성에 한계가 있었다. 지방정부의 과학기술예산 및 전담조직, 산업경제예산 및 전담 조직의 부족과 미 정착으로 독자적인 지역과학기술정책이나 지역산업정책은 물론이고 지역혁신정책을 수행하기 어려웠으나, 지역의 특성과 잠재력에 맞는 사업을 발굴하여 중앙정부에 건의하고 지역 내 각 프로젝트를 총괄 조정하는 중개자 역할을 지역전략산업기획단이 그 역할을 수행하고 있다. 지역혁신체제의 중심기관으로 중개기관과 협력 프로그램에 의한 플랫폼 구축 및 지역산업발전의 기획${\sim}$조정기구로서, 선진국의 지역발전기구(Regional Development Agency : RDA)인 지역전략산업기획단이 2002년도부터 산업자원부와 9개 시도에 의해 설립되어 지역네트워크의 활성화와 클러스터의 형성 촉진을 하게 되었고 2004년도에는 13개시도로 확대${\sim}$운영되고 있고, 지역특화사업(H/W)과 지역산업기술개발과제(S/W)와 함께 패케지 형태로 지원되며, 주요역할은 크게 지역산업의 정책기획 분야와 평가관리, 지역혁신역량 조사 및 DB구축 등으로 구분된다. 그중에서도 권역별, 지역별, 지역산업진흥사업 육성과 중장기 산업발전계획을 수립하기 위하여 지역혁신역량을 바탕으로 한 지역 Technology Road Map(TRM)작성사업은 전국공통의 1단계 사업으로 실시 ?榮쨉?, 2005년 3월 기준으로 9개 지역(강원, 대전, 충남, 충북, 경북, 울산, 전남, 전북, 제주) 26개 산업분야를 대상으로 23개가 완료된 상황이다. 이를 근거로 한 지역정책과 R&D 과제 및 필요 인프라의 도출이 체계적으로 구축되어 지역산업 발전을 위한 기술역량이 강화될 것이다.

For the reasonable use of low grade-shallow geothermal energy by Standing Column Well(SCW) system, the basic requirements are depth-wise increase of earth temperature like $2^{\circ}C$ per every 100m depth, sufficient amount of groundwater production being about 10 to 30% of the design flow rate of GSHP with good water quality and moderate temperature, and non-collapsing of borehole wall during reinjection of circulating water into the SCW. A closed loop type-vertical ground heat exchanger(GHEX) with $100{\sim}150m$ deep can supply geothermal energy of 2 to 3 RT but a SCW with $400{\sim}500m$ deep can provide $30{\sim}40RT$ being equivalent to 10 to 15 numbers of GHEX as well requires smaller space. Being considered as an alternative of vertical GHEX, many numbers of SCW have been widely constructed in whole country without any account for site specific hydrogeologic and geothermal characteristics. When those are designed and constructed under the base of insufficient knowledges of hydrgeothermal properties of the relevant specific site as our current situations, a bad reputation will be created and it will hamper a rational utilization of geothermal energy using SCW in the near future. This paper is prepared for providing a guideline of SCW design comportable to our hydrogeothermal system.

The value of lithium has significantly increased due to the rising demand for electric cars and batteries. Lithium is primarily found in pegmatites, hydrothermally altered tuffaceous clays, and continental brines. Globally, groundwater-fed salt lakes and oil field brines are attracting attention as major sources of lithium in continental brines, accounting for about 70% of global lithium production. Recently, deep groundwater, especially geothermal water, is also studied for a potential source of lithium. Lithium concentrations in deep groundwater can increase through substantial water-rock reaction and mixing with brines. For the exploration of lithim in deep groundwater, it is important to understand its origin and behavior. Therefore, based on a nationwide preliminary study on the hydrogeochemical characteristics and evolution of thermal groundwater in South Korea, this study aims to investigate the distribution of lithium in the deep groundwater environment and understand the geochemical factors that affect its concentration. A total of 555 thermal groundwater samples were classified into five hydrochemical types showing distinct hydrogeochemical evolution. To investigate the enrichment mechanism, samples (n = 56) with lithium concentrations exceeding the 90th percentile (0.94 mg/L) were studied in detail. Lithium concentrations varied depending upon the type, with Na(Ca)-Cl type being the highest, followed by Ca(Na)-SO₄ type and low-pH Ca(Na)-HCO₃ type. In the Ca(Na)-Cl type, lithium enrichment is due to reverse cation exchange due to seawater intrusion. The enrichment of dissolved lithium in the Ca(Na)-SO₄ type groundwater occurring in Cretaceous volcanic sedimentary basins is related to the occurrence of hydrothermally altered clay minerals and volcanic activities, while enriched lithium in the low-pH Ca(Na)-HCO₃ type groundwater is due to enhanced weathering of basement rocks by ascending deep CO₂. This reconnaissance geochemical study provides valuable insights into hydrogeochemical evolution and economic lithium exploration in deep geologic environments.

In this paper, we attempted to provide the bases of effective educational programs for fostering ICT competencies of gifted students in science. For this purpose, we tried to answer the questions like 'What are the ICT core-competence for gifted students in science?' and 'How can we educate those competencies effectively?' We started by reviewing existing studies on ICT competencies for talented people in future society and then adopted one[6] as the basis for further validation. We tried to work with as many G/T experts as possible, and decided to use the online survey methodology because the experts are scattered all over the country. The survey was sent to the corresponding person who is in charge of G/T education in each area, and then e-mailed to G/T experts in that area. Through these procedures, three hundred four(304) G/T experts from all around the country participated in this survey. The results showed the followings: (1) G/T experts agreed with the importance and necessity of ICT competencies for gifted students in science; (2) G/T experts agreed with the validity of three core ICT competencies, which are 'knowledge and skills competence, creativity competence, and characteristic competence,' for gifted students in science; (3) G/T experts agreed with the validity of educational goals, which are suggested for fostering each ICT core-competence of gifted students in science; and (4) G/T experts regarded 'product-oriented education' and 'ICT device-oriented education' as important and effective types of education programs for fostering ICT competencies of gifted students in science.

This study selected indicators that can represent the characteristics of general hospitals, including local medical centers and Red Cross hospitals, which are representative public health institutions, and analyzed clusters. And we present to benchmark in each cluster. According to the analysis, 276 general hospitals were classified into 13 clusters, and local medical centers and Red Cross hospitals were classified into clusters between 1 and 7 of the total 13 clusters because of their small size. Local medical centers and Red Cross hospitals, selected as excellent hospitals in each cluster, showed significant differences in management performance despite similar regional environment and medical performance, and among them, surgical consultation and internal medical care rates, inpatient and outpatient rates. In order for local medical centers and Red Cross hospitals to play their role as secondary acute hospitals in the region, inpatient care services and surgical functions must be activated.

This study suggests a macroscopic method of evaluating forest recreation function based on physical characteristics of forests. The method was verified by a correlation between forest recreation function in popular top 45 mountains and popularity among them, with using data-mountain area, height, distance between mountain and cities, population around mountain, and size of public service. According to analysis of the forest recreation function, it is shown that top 8 mountains, including Jirisan and Seoraksan, provide over 64% of total recreation function, while they serve the function relatively lower than mountains near mega cities-Bukhansan in Seoul-do, in terms of the function per unit area ($km^2$). It is because, in a case of national and provincial mountains, the size of mountain is likely a critical factor for determining recreation function and the distance influences on it relatively lower. These findings implicate that a large size of forests bring the recreation function to visitors on nationwide level, whileas forests in suburban provide intensively it to near population to near population.

Hydrogen energy technology is gaining importance in the era of the Fourth Industrial Revolution, offering military advantages when applied to military vehicles due to its characteristics such as reduced greenhouse gas emissions, noise, and low vibration. Korea's military has initiated the Army Tiger 4.0 plan, focusing on hydrogen application, downsizing, and AI-based smart features. The Ministry of National Defense plans to collaborate with the Ministry of Environment to expand hydrogen charging stations nationwide, anticipating increased deployment of military hydrogen vehicles. However, considering the Jet Fire and VCE(Vapor Cloud Explosion) nature of hydrogen, ensuring safety during installation is crucial. Current military guidelines specify a minimum safety distance of 2m from adjacent buildings for charging stations. Scientific methods have been employed to quantitatively assess the accident damage range of hydrogen, proposing a minimum safety distance beyond the affected area.
