본 연구는 지형자료와 Free-air 중력이상을 이용하여 한반도의 모호면 심도 및 지각두께를 계산하였다. Airy-Heiskanen 지각평형 가설에 근거한 Free-air 중력이상에 포함된 지형중력과 연관성 있는 성분들을 파동수상관분석으로 추출하고 이로부터 보상이 이루어진 상태의 중력효과를 계산하였다. 계산된 결과로부터 반복법을 통한 역산을 이용하여 지각과 맨틀의 경계면인 모호면 심도를 도출하였고 역산 시 기존에 연구된 지진파에 의한 20개의 모호면 심도를 활용하여 포텐셜 필드에서 나타날 수 있는 비유일성의 가능성을 최소화하였다. 최종적으로 모호면 심도와 고도 자료를 더하여 한반도 지각두께를 도출하였으며 한반도 평균지각두께는 32.15 km, 표준편차 3.12 km를 나타내었다. 이 연구에서 구한 남한지역의 모호면과 같은 지역의 타 논문결과들과 비교하였을 때 평균 모호면 심도는 각각 31.08 km, 31.96 km, 33.02 km을 나타내고 표준편차는 1.94 km, 1.62 km, 1.77 km을 나타냄으로 각 연구결과의 통계치는 거의 일치하는 것으로 나타났고 모호면 굴곡 역시 공통적으로 태백산맥과 소백산맥을 따라 모호면이 깊어지고 경상분지는 얕아짐을 확인하였다. 또한 지각 내 중력 이상체의 분포에 대한 정보를 포함하고 있는 지형과 비상관된 Freeair 중력이상을 가지고 지열류량분포와 비교하였다. 저주파성분의 지형과 비상관된 Free-air 중력이상과 지열류량분포를 상관 비교한 결과 높은 양의 상관관계를 나타냈고, 특히, 경상분지지역은 높은 지열류량분포가 암석의 밀도보상으로 인해 모호면의 상승을 가져다 준 것으로 보인다. 이러한 결과는 최근 Kim et al.(2008)에서 언급한 경상분지의 높은 지열류량이 맨틀로부터 야기되는 모델과 부합된다는 사실을 뒷받침해주고 있다. We study the deep structure of Korean Peninsula by estimating Moho depth and crustal thickness from using land and oceanic topography and free-air gravity anomaly data. Based on Airy-Heiskanen isostatic hypothesis, the correlated components between the terrain gravity effects and free-air gravity anomalies by wavenumber correlation analysis(WCA) are extracted to estimate the gravity effects that will be resulted from isostatic compensation for the area. With the resulting compensated gravity estimates, Moho depth that is a subsurface between the crust and mantle is estimated by the inversion in an iterative method with the constraints of 20 seismic depth estimates by the receiver function analysis, to minimize the uncertainty of non-uniqueness. Consequently, the average of the resulting crustal thickness estimate of Korean Peninsula is 32.15 km and the standard deviation is 3.12 km. Moho depth of South Korea estimated from this study is compared with the ones from the previous studies, showing they are approximately consistent. And the aspects of Moho undulation from the respective study are in common deep along Taebaek Mountains and Sobaek Mountains and low depth in Gyeongsang Basin relatively. Also, it is discussed that the terrain decorrelated free-air gravity anomalies inferring from the intracrustal characteristics of the crust are compared to the heat flow distributions of South Korea. The low-frequency components of terrain decorrelated Free-air gravity anomalies are highly correlated with the heat flow data, especially in the area of Gyeongsang basin where high heat flow causes to decrease the density of the rocks in the lower crust resulting in lowering the Moho depth by compensation. This result confirms that the high heat sources in this area coming from the upper mantle by Kim et al. (2008).

최순영,이명혜,황문옥,민경희,Choi, Soon-Young,Lee, Myung-Hye,Hwang, Moon-Ok,Min, Kyung-Hee The Microbiological Society of Korea 1994 미생물학회지 Vol.32 No.2

Xanthomonas campestris M12는 octane을 분해할 수 있는 OCT 플라스미드를 갖고 있으며, 이 플라스미드의 분해 능력으로 $C_8$에서 $C_{16}$까지의 n-alkane을 이용할 수 있었다. X. campestris M12 균주는 n-alkane을 이용하여 alcohol, aldehyde, fatty acid를 거쳐서 분해할 수 있으나 heanoic acid, adipic acid, pimelic acid 그리고 heptanal은 이용할 수 없었다. 또한 이 균주는 straight fatty acids의 monoterminal oxidation과 diterminal oxidation에 의하여 n-alkane을 분해할 수 있으며, branched-chain alkane도 이용할 수 있었다. Xanthomonas campestris M12 carrying OCT plasmid which could dissimilate octane was able to utilize n-alkanes of eight to sixteen carbon atoms via the capacity of this plasmid. M12 strain could utilize terminal oxidation products of these primary, alkanes, alcohols, aldehydes and fatty acids but not hexanoic acid, adipic acid, pimelic acid and heptanal. This strain also biodegraded n-alkanes by monoterminal or diterminal oxdation of straight-chain fatty acids, and branched-chain alkane.

The main purpose of this study is to draw policy alternatives for improving recruitment, promotion, and reward system in police service. Methodology in this study includes literature study and questionnaire survey. The questionnaire survey was delivered to the civil servants who belong to police. Interviews with the retired civil servants as well as the incumbent in police service were conducted in order to complement the findings of the questionnaire survey. The recruitment and promotion system serves as the foundation of the framework of this study. The recruitment system includes such analysis units as competitive recruitment examination, non-competitive recruitment examination, open position. The promotion system includes such analysis units as criteria for promotion, job posting, performance appraisal, 360-degree appraisal system, performance appraisal on senior civil servants. Based on these analysis units, the items of questionnaire survey were drawn in detail. This study presents alternatives for improving recruitment and promotion system in Police Service as follows. 1. Enhancing fairness and transparency It is necessary to reduce an entrance quota of Korea National Police University(KNPU) and to increase the transparency of review committee for selection of a candidate from registers of eligibles. The formal written test should be maintained only for promotion to such classes as police lieutenant and police major. It is necessary to facilitate 360-degree appraisal and to introduce customer evaluation. 2. Increasing competitiveness and openness It is necessary to increase the rate of non-competitive recruitment examinations for hiring individuals with certain academic degrees or certificates up to 10% as a means of introducing flexible and diverse recruitment methods to meet the changing demand in police service. Positions that can be filled by substituted individuals from the private sector should be ready for open recruitment. Job posting program which is a competitive recruitment system within the government should gradually be expanded on the selection process for the vacant positions. A minimum 5% quota in the promotion to a grade of police superintendent should be maintained for those who were employed into police service as a grade of policeman. Human nature and eligibility as a police should be evaluated on probationary period, and the person disqualified a police position should be excluded. 3. Increasing job specialty and competency It is necessary to increase the weight of the test of aptitude and physical strength in the open competitive recruitment system. Background investigation is also needed to ensure the integrity of police. It is necessary to administer comprehensive aptitude test periodically and to use its results in assignment to a position or removal from office by official authority.

This paper aims to draw policy alternatives for improving rank and pay system of civil servants responsible for agricultural education and extension service. The civil servants responsible for agricultural education and extension service are classified as General Service, but their 9 ranks system was transferred to 2 ranks system in 1986 because of their professional traits. The civil servants in the lower rank have experienced demoralization. demanding single rank and pay system. In order to identify recognition, behavior. and preference of the civil servants with regard to the current rank and pay system. pay principle. and equity and transparency of current personnel decision, the method of questionnaire survey was used. This study presents the rough improvements of rank and pay system based not only on the results of the empirical analyses of the questionnaires, but also on the directions of the current civil service system reform throughout the government. The direction of civil service system in relation to agricultural education and extension service is to reinforce position classification in order to meet the need of specialization. It is imperative to change the current rank-in-person into rank- in-position system. The new pay system should be based on not only the degree of difficulty and responsibility of the position. but also performance-related pay. However, it is difficult to entirely ignore the rule of seniority. In conclusion. it is rational that the new pay table should cover the rule of seniority, the degree of difficulty and responsibility of the position. and merit pay. In case of the introduction of single rank and pay system, the coverage of the pay level of the single rank and pay table should be obviously lowered than those of the current two rank and pay tables. In addition to this single rank and pay table in which the pay rate may be designed to reflect the rule of seniority and annual salary increments are small. it is necessary to keep additional pay table in which pay rate is determined by the grade of position based on position classification and pay range in each grade can reflect the results of performance appraisal. Several years of pretesting of pay-for-performance plans are a prerequisite for successful results. Time is needed in the efforts to develop effective performance-related pay system functioning as motivator to perform jobs well.

이번 연구에서는 해저열수광상 유망지역을 분석하기 위해서 남서태평양 라우분지에 TA (Tofua Arc) 22 해저산에 대하여 해저지형조사 및 지자기조사를 실시하였다. 획득한 자료로부터 연구지역의 지자기 및 해저지구조를 분석하였다. TA 22 해저산의 해저지형은 정상부가 서쪽과 동쪽으로 나뉘어져 구성되어 있으며 각각 정상부마다 칼데라가 형성되어 있다. 서쪽 칼데라는 동쪽 칼데라에 비해 정상부 직경은 작은 반면 더욱 깊게 함몰되어 있다. TA 22 해저산의 사면경사도는 각 칼데라마다 조금의 차이는 있으나 수심 약 -1,000 m을 기점으로 경사가 급해지고 정상부에서는 비교적 경사가 완만하다. TA 22 해저산의 지자기 특성을 종합하면 칼데라의 정상부 및 주변에서 강한 고이상대가 존재한다. 저자화대는 주로 칼데라 바깥 사면 및 안쪽 중심부에 나타난다. 이러한 특징들은 기존 연구에서 열수광상이 나타났던 칼데라 정상부 안쪽이나 또는 정상부 바깥쪽 사면에 고이상대와 저자화대가 나타나는 것과 유사한 특성을 지닌다. 탄성파단면자료와 비교하여 자력모델링을 한 결과, 각 측선들의 모델 값과 측정값의 차이인 RMSE값은 약 20 nT를 나타내어 연구지역에 대한 자력 모델링한 결과가 측정 결과와 잘 부합되어진다고 판단된다. 모델링과 자화분포에 의한 열수광상 부존예상지역은 칼데라들의 안쪽이나 칼데란 주변 지역에 위치할 것으로 추정된다. We acquired the magnetic and bathymetry data around the TA (Tofua Arc) 22 seamount in the Lau Basin for finding submarine hydrothermal deposits. From the data, we estimated the magnetic characteristics in the study area. The bathymetry shows that TA 22 seamount consists of the western and eastern summits. Each summit exhibits a caldera. The western caldera is smaller, but deeper than the eastern caldera. The slope gradients of the TA 22 are steeper around ~1000 m depth range and relatively gentle at the summit areas with the small difference of two calderas. The magnetic properties of TA 22 seamount present high anomalies at the summit and the vicinity of the caldera. Low magnetization zones appear over the outer flanks and center of the calderas. These magnetic patterns are similar to the previous studies which had represented high anomalies and low magnetization zones inside of the summit area or on the flank of the outside of the summit area. The results of the 2D magnetic forward modeling with seismic profiles show about 20 nT of RMSEs (root mean square error) between the modeled and observed values. The low RMSEs proposes a good correlation between the modeled 2D structure and the geophysical observation in this study area. Based on the modeling and magnetization distribution, hydrothermal deposits are predicted to be located at the inner area of the calderas or at small mounds around caldera rims.

일반 논문 : 저탄소 녹색성장에 대한 환경정치학적 성찰

최순영 ( Soon Young Choi ) 한국환경철학회 2010 환경철학 Vol.0 No.10

본 논문은 2008년 8. 15 광복절 경축사에서 이명박 대통령이 제시한 저탄소 녹색성장에 대한 환경정치학적 성찰을 목적으로 한다. 이명박 대통령은 새로운 국가발전 모델로 저탄소 녹색성장을 내세웠다. 그리고 한국이 녹색성장의 세계적 리더로 나설 것임을 천명하였다. 2009년 12월 코펜하겐에서 개최된 유엔기후변화협약은(UNFCCC) 저탄소 녹색성장의 문제가 단지 미래의 국가비젼만이 아니라 모든 국가의 정치, 경제에 상당한 영향을 미칠 중요한 전지구적 현실임을 보여주었다. 이러한 점에서 이명박 정부가 제시한 저탄소 녹색성장 정책은 현실로 다가온 지구온난화에 대응하기 위한 CO2 감축, 산업구조의 변화, 화석 에너지 중심의 에너지 소비구조와 소비만능의 생활구조 변화의 필연성을 인지한 시의적절한 정책이라는 점에서 환영받을 만하다. 그러나 녹색과 성장을 어떻게 조화시킬 것인가, 민주화 이후의 민주주의의 심화과정에서 대의 민주주의와 의회 민주주의의 한계를 넘어서는 보다 민주적이고 효율적인 정치체제의 건설은 해결과제로 남아있다. 이점에서 보았을 때 저탄소 녹색성장은 많은 아쉬운 점을 갖고 있다. 첫째, 기존의 산업화와 생활방식에 대한 철학적 반성의 부재와 블루오션의 관점에서 저탄소 녹색성장을 바라보는 시장중심주의에 치우친 인식. 둘째, CO2 감축을 위한 전략으로서 원자력 확대정책. 셋째, 녹색과 성장을 일치시키기 위해서 필요한 기존 민주주의의 생태 민주주의적 전환 시도의 미약함을 들 수 있다. 그리고 이러한 문제는 비단 정부만의 문제로 국한되지 않는다. 문제는 환경정치학과 생태 민주주의 담론을 주도하고 있지 못하는 정치학계, 대학교에서의 관련 강좌의 부족, 시민사회와 함께하는 생태 민주주의적 교육과 제도들의 빈약함에서도 드러난다. In this paper, the policy of Low Carbon, Green Growth which has been announced by president Lee, Myung-bak on the 63th anniversary of korean independency from the japanese colonial occupation, is to be investigated from the viewpoint of environmental politics. President Lee, Myung-bak has declared Low Carbon, Green Growth policy as the new paradigm of national sustainable development and emphasized that Korea will be a global leader of the policy. UNFCCC Copenhagen in december 2009 proved that Low Carbon, Green Growth isn`t only a new national development strategy but also the global reality which influences economy and politics of the whole world. At that point the policy of Low Carbon, Green Growth is an adequate measure to face the problem of global warming, reduction of CO2 emission, transformation of the industrial structure, new energy policy and radical change of mass consumption life style. But there are some important problems to be resolved; how could the economic development be compatible with green environment, consolidation and remodeling of democracy which overcome the ecological limits of representative, parliamentary democracy. The Low Carbon, Green Growth policy of korean government has many unsatisfied defects. First of all, there is no critical reflections of korean industrialization history, and the market oriented understanding of Low Carbon, Green Growth policy in the light of blue ocean. Second, the expansion of nuclear energy as a strategy to reduce CO2. Third, the lack of ecological reconstruction of democracy to harmonize the economic growth with the green politics. These problems don`t affect only government but also the korean academic world of political science which doesn`t lead the discourses of environmental politics. Deficiency of lectures of ecological politics in universities and in civil society of Korea is also to be resolved.
