연구목적: 이 연구는 서울시 10개 수소충전소의 공간적 접근성 분석을 실시하고, 접근이 어려운 지역을 식별하였다. 입지의 형평성과 안전성 측면에서 신규 입지를 추가하여 접근성을 분석을 다시 수행한 후, 개선 효과 비교를 통해 시사점을 도출하는 것을 목적으로 한다. 연구방법: ArcGIS 프로그램의 네트워크 분석 기반의 입지배분(Location-Allocation) 모형과 이용권역(Service Area) 모형을 적용하여 접근이 취약한 지역을 식별하였다. 입지선정 방분석 기반의 입지배분(Location-Allocation) 모형과 이용권역(Service Area) 모형을 적용하여 접근이 취약한 지역을 식별하였다. 입지선정 방법은 부족한 수소충전소에 신속한 도착이 필요한 점을 고려하여 '최소시설 수로 최대수요를 확보하도록 함(Minimize Facilities)' 방법을 적용하였다. 특정한 시간 내의 도착을 위한 한계 거리는 서울시 2022년 평균 차량통행속도(23.1km/h, 서울시 열린데이터 광장)를 적용하여 10분 이동가능 거리인 3,850m과 5,775m(15분) 그리고 7,700m(20분)의 세 가지로 분하여 분석하였다. 신규 입지는 수소충전소 설치에 대한 갈등을 최소화하기 위하여 산업통상자원부의 특례기준1)을 적용하여 기존의 주유소, LPG/CNG 충전소 중에서 수소충전소 추가 설치가 가능한 후보지를 도출하였다. 연구결과: 분석 결과, 최종적으로 상세 현황 검토를 통해 추가 후보지 5개소가 도출되었다. 기존 10개의 수소충전소에 20분 이내 접근이 취약한 지역을 중심으로 상대적으로 안전한 기존 주유소와 LPG/CNG 충전소에 신규 수소충전소 5개소를 설치하면 접근성이 크게 개선됨을 확인할 수 있었다. 그럼에도 불구하고 여전히 접근이 어려운 지역이 있는 것으로 나타났다. 결론: 입지배분모형을 이용하여 수소충전소 접근이 어려운 지역을 식별하고, 설치의 우선순위를 부여한다면 과학적 근거 기반 수소충전소 입지 선정을 위한 의사결정을 지원할 수 있다.
조선왕조의 기록관리 전통의 맥이 끊어진지 거의 한세기가 지난 1999년도에 한국은 "공공기관의 기록물관리에 관한 법률"을 제정 시행함으로써 기록관리의 새로운 시대를 맞이했다. 조선왕조실록에는 국사 전반에 걸쳐 오백년 간의 중요한 역사적 사실들이 기록되었다. 이것은 인류역사상 주요한 업적이며 전세계적으로 귀한 사례이다. 이것이 가능했던 것은 실록이 누대(累代)의 사관들이 저술하고 편찬한 일차자료인 기록물을 수집, 선정한 것이기 때문이다. 근대적 기록보존소에서는 중요한 공공기록물이 원형대로 보존될 필요가 있기 때문에 기록보존을 위해 중요한 국가 기록물을 평가 선별하는 근대적 기록보존제도를 확립해야 했다. 그러나 일제에 의한 식민지화로 그 기회를 빼앗겼고 우리의 훌륭한 기록보전 전통은 계승되지 못했다. 중앙화된 기록보존제도는 1969년 총무처에 정부기록보존소를 설립함으로써 발전하기 시작했다. 정부기록보존소는 조선왕조의 사고 전통을 계승해서 1984년 부산에 현대적 사고시설을 건축했다. 1998년 정부기록보존소는 대전정부종합청사로 본부를 이전하고 첨단 시청각기록물 서고를 갖추었다. 1996년부터 정부기록보존소는 마이크로필름 보존을 보완하고 수작업 등록시스템을 개선하기 위하여 기록물 관리시스템 전산화를 도입했다. 소장 기록물의 디지털화는 이용자에게 디지털 이미지를 제공하기 위한 주요한 사업이었다. 이를 위해 정부기록보존소는 새로 컴퓨터/서버 시스템을 구입하고 응용 소프트웨어를 개발했다. 이와 병행하여 정부기록보존소는 역사학 및 문헌정보학 배경을 가진 아키비스트들을 증원하여 고도의 전문화를 이루는 방향으로 인력구조를 크게 혁신하였다. 보존연구직과 전산직 역시 채용되었다. 새로운 기록물관리법은 2000년 1월 1일부터 시행되고 있다. 이 법은 한국의 기록물관리에 있어 다음과 같은 변화를 가져왔다. 첫째, 이 법은 입법 사법 행정부, 헌법기관, 육해공군, 국가정보원 등 모든 공공기관의 기록물을 규정한다. 범국가적으로 통일된 기록물관리체계가 갖추어지게 되었다. 둘째, 각 기관의 수준별로 공공기록물 관리 기관을 두게 되었다. 중앙기록물관리기관, 국회 및 사법부에 특수기록물관리기관, 대도시 및 도에 지방기록물 관리기관, 공공기관에 자료관 또는 특수자료관, 각 과단위에서는 기록물관리책임자가 기록관리를 책임지게 되었다. 셋째, 공공기관의 기록물은 생산시에 컴퓨터에 등록된다. 따라서 인터넷이나 컴퓨터망을 통해 기록물을 쉽게 추적, 검색할 수 있게 될 것이다. 넷째, 기록관리학 분야에서 전문적 훈련을 받은 기록물관리 전문요원 배치를 의무화함으로써 기록물의 전문적 관리를 보장하게 된다. 다섯째, 공공기록물의 불법적 처리는 처벌을 받을 수 있는 범죄를 구성한다. 앞으로 공공기록물관리는 한국정부의 '전자정부 추진정책'과 함께 발전할 것이다. 다음과 같은 변화가 예상된다. 첫째 공공기관에서는 전자결재 문서 외에 종이문서, 시청각기록물, 간행물 등도 모두 디지털화하여 행정의 효율화 및 생산성을 제고할게 될 것이다. 둘째, 국회는 이미 특수기록관을 설립하였다. 법원과 국가정보원도 뒤를 따를 것이다. 시도 차원에서 더 많은 기록관들이 설립될 것이다. 셋째, 우리 사회가 지식정보사회화 될수록 기록관리기능은 더욱 중요한 국가기능이 될 것이다. 더 많은 대학교, 학회, 시민단체들이 기록보존에 고한 인식제고에 참여하고, 기록보존운동이 범국민적 차원으로 심화될수록 한국의 기록물관리는 현재보다 눈에 띄게 발전할 것이다.
Just before the Korean War, the total number of the North Korean troops was 198,380, while that of the ROK(Republic of Korea) army troops 105,752. That is, the total number of the ROK army troops at that time was 53.3% of the total number of the North Korean army. As of December 2008, the total number of the North Korean troops is estimated to be 1,190,000, while that of the ROK troops is 655,000, so the ROK army maintains 55.04% of the total number of the North Korean troops. If the ROK army continues to reduce its troops according to [Military Reform Plan 2020], the total number of its troops will be 517,000 m 2020. If North Korea maintains the current status(l,190,000 troops), the number of the ROK troops will be 43.4% of the North Korean army. In terms of units, just before the Korean War, the number of the ROK army divisions and regiments was 80% and 44.8% of North Korean army. As of December 2008, North Korea maintains 86 divisions and 69 regiments. Compared to the North Korean army, the ROK army maintains 46 Divisions (53.4% of North Korean army) and 15 regiments (21.3% of North Korean army). If the ROK army continue to reduce the military units according to [Military Reform Plan 2020], the number of ROK army divisions will be 28(13 Active Division, 4 Mobilization Divisions and 11 Local Reserve Divisions), while that of the North Korean army will be 86 in 2020. In that case, the number of divisions of the ROK army will be 32.5% of North Korean army. During the Korean war, North Korea suddenly invaded the Republic of Korea and occupied its capital 3 days after the war began. At that time, the ROK army maintained 80% of army divisions, compared to the North Korean army. The lesson to be learned from this is that, if the ROK army is forced to disperse its divisions because of the simultaneous invasion of North Korea and attack of guerrillas in home front areas, the Republic of Korea can be in a serious military danger, even though it maintains 80% of military divisions of North Korea. If the ROK army promotes the plans in [Military Reform Plan 2020], the number of military units of the ROK army will be 32.5% of that of the North Korean army. This ratio is 2.4 times lower than that of the time when the Korean war began, and in this case, 90% of total military power should be placed in the DMZ area. If 90% of military power is placed in the DMZ area, few troops will be left for the defense of home front. In addition, if the ROK army continues to reduce the troops, it can allow North Korea to have asymmetrical superiority in military force and it will eventually exert negative influence on the stability and peace of the Korean peninsular. On the other hand, it should be reminded that, during the Korean War, the Republic of Korea was attacked by North Korea, though it kept 53.3% of troops, compared to North Korea. It should also be reminded that, as of 2008, the ROK army is defending its territory with the troops 55.04% of North Korea. Moreover, the national defense is assisted by 25,120 troops of the US Forces in Korea. In case the total number of the ROK troops falls below 43.4% of the North Korean army, it may cause social unrest about the national security and may lead North Korea's misjudgement. Besides, according to Lanchester strategy, the party with weaker military power (60% compared to the party with stronger military power) has the 4.1% of winning possibility. Therefore, if we consider the fact that the total number of the ROK army troops is 55.04% of that of the North Korean army, the winning possibility of the ROK army is not higher than 4.1%. If the total number of ROK troops is reduced to 43.4% of that of North Korea, the winning possibility will be lower and the military operations will be in critically difficult situation. [Military Reform Plan 2020] rums at the reduction of troops and units of the ground forces under the policy of 'select few'. However, the problem is that the financial support to achieve this goal is not secured. Therefore, the promotion of [Military Reform Plan 2020] may cause the weakening of military defence power in 2020. Some advanced countries such as Japan, UK, Germany, and France have promoted the policy of 'select few'. However, what is to be noted is that the national security situation of those countries is much different from that of Korea. With the collapse of the Soviet Unions and European communist countries, the military threat of those European advanced countries has almost disappeared. In addition, the threats those advanced countries are facing are not wars in national level, but terrorism in international level. To cope with the threats like terrorism, large scaled army trops would not be necessary. So those advanced European countries can promote the policy of 'select few'. In line with this, those European countries put their focuses on the development of military sections that deal with non-military operations and protection from unspecified enemies. That is, those countries are promoting the policy of 'select few', because they found that the policy is suitable for their national security environment. Moreover, since they are pursuing common interest under the European Union(EU) and they can form an allied force under NATO, it is natural that they are pursing the 'select few' policy. At present, NATO maintains the larger number of troops(2,446,000) than Russia(l,027,000) to prepare for the potential threat of Russia. The situation of japan is also much different from that of Korea. As a country composed of islands, its prime military focus is put on the maritime defense. Accordingly, the development of ground force is given secondary focus. The japanese government promotes the policy to develop technology-concentrated small size navy and air-forces, instead of maintaining large-scaled ground force. In addition, because of the 'Peace Constitution' that was enacted just after the end of World War II, japan cannot maintain troops more than 240,000. With the limited number of troops (240,000), japan has no choice but to promote the policy of 'select few'. However, the situation of Korea is much different from the situations of those countries. The Republic of Korea is facing the threat of the North Korean Army that aims at keeping a large-scale military force. In addition, the countries surrounding Korea are also super powers containing strong military forces. Therefore, to cope with the actual threat of present and unspecified threat of future, the importance of maintaining a carefully calculated large-scale military force cannot be denied. Furthermore, when considering the fact that Korea is in a peninsular, the Republic of Korea must take it into consideration the tradition of continental countries' to maintain large-scale military powers. Since the Korean War, the ROK army has developed the technology-force combined military system, maintaining proper number of troops and units and pursuing 'select few' policy at the same time. This has been promoted with the consideration of military situation in the Koran peninsular and the cooperation of ROK-US combined forces. This kind of unique military system that cannot be found in other countries can be said to be an insightful one for the preparation for the actual threat of North Korea and the conflicts between continental countries and maritime countries. In addition, this kind of technology-force combined military system has enabled us to keep peace in Korea. Therefore, it would be desirable to maintain this technology-force combined military system until the reunification of the Korean peninsular. Furthermore, it is to be pointed out that blindly following the 'select few' policy of advanced countries is not a good option, because it is ignoring the military strategic situation of the Korean peninsular. If the Republic of Korea pursues the reduction of troops and units radically without consideration of the threat of North Korea and surrounding countries, it could be a significant strategic mistake. In addition, the ROK army should keep an eye on the fact the European advanced countries and Japan that are not facing direct military threats are spending more defense expenditures than Korea. If the ROK army reduces military power without proper alternatives, it would exert a negative effect on the stable economic development of Korea and peaceful reunification of the Korean peninsular. Therefore, the desirable option would be to focus on the development of quality of forces, maintaining proper size and number of troops and units under the technology-force combined military system. The tableau above shows that the advanced countries like the UK, Germany, Italy, and Austria spend more defense expenditure per person than the Republic of Korea, although they do not face actual military threats, and that they keep achieving better economic progress than the countries that spend less defense expenditure. Therefore, it would be necessary to adopt the merits of the defense systems of those advanced countries. As we have examined, it would be desirable to maintain the current size and number of troops and units, to promote 'select few' policy with increased defense expenditure, and to strengthen the technology-force combined military system. On the basis of firm national security, the Republic of Korea can develop efficient policies for reunification and prosperity, and jump into the status of advanced countries. Therefore, the plans to reduce troops and units in [Military Reform Plan 2020] should be reexamined. If it is difficult for the ROK army to maintain its size of 655,000 troops because of low birth rate, the plans to establish the prompt mobilization force or to adopt drafting system should be considered for the maintenance of proper number of troops and units. From now on, the Republic of Korean government should develop plans to keep peace as well as to prepare unexpected changes in the Korean peninsular. For the achievement of these missions, some options can be considered. The first one is to maintain the same size of military troops and units as North Korea. The second one is to maintain the same level of military power as North Korea in terms of military force index. The third one is to maintain the same level of military power as North Korea, with the combination of the prompt mobilization force and the troops in active service under the system of technology-force combined military system. At present, it would be not possible for the ROK army to maintain such a large-size military force as North Korea (1,190,000 troops and 86 units). So it would be rational to maintain almost the same level of military force as North Korea with the combination of the troops on the active list and the prompt mobilization forces. In other words, with the combination of the troops in active service (60%) and the prompt mobilization force (40%), the ROK army should develop the strategies to harmonize technology and forces. The Korean government should also be prepared for the strategic flexibility of USFK, the possibility of American policy change about the location of foreign army, radical unexpected changes in North Korea, the emergence of potential threat, surrounding countries' demand for Korean force for the maintenance of regional stability, and demand for international cooperation against terrorism. For this, it is necessary to develop new approaches toward the proper number and size of troops and units. For instance, to prepare for radical unexpected political or military changes in North Korea, the Republic of Korea should have plans to protect a large number of refugees, to control arms and people, to maintain social security, and to keep orders in North Korea. From the experiences of other countries, it is estimated that 115,000 to 230,000 troops, plus ten thousands of police are required to stabilize the North Korean society, in the case radical unexpected military or political change happens in North Korea. In addition, if the Republic of Korea should perform the release of hostages, control of mass destruction weapons, and suppress the internal wars in North Korea, it should send 460,000 troops to North Korea. Moreover, if the Republic of Korea wants to stop the attack of North Korea and flow of refugees in DMZ area, at least 600,000 troops would be required. In sum, even if the ROK army maintains 600,000 troops, it may need additional 460,000 troops to prepare for unexpected radical changes in North Korea. For this, it is necessary to establish the prompt mobilization force whose size and number are almost the same as the troops in active service. In case the ROK army keeps 650,000 troops, the proper number of the prompt mobilization force would be 460,000 to 500,000.
