본 연구는 계방산 가문비나무 및 전나무 임분의 산림식생유형분류와 정량적 분석을 위하여 Z-M 식물사회학적 방법으로 식생구조의 유형분류를 실시한 결과, 군락단위에서 가문비나무군락, 전나무군락으로 분류되었으며 가문비나무군락은 군단위에서 흰인가목군과 부게꽃나무군으로 세분되었으며, 전나무군락은 복장나무군과 생강나무군으로 세분되었다. 분류된 식생단위를 기준으로 중요치를 산출한 결과, 가문비나무는 식생단위 1과 2의 교목층에서 각각 30.73%, 20.25%로 비교적 높게 나타나 당분간 가문비나무의 우점이 계속될 것이라 판단되었다. 또한 종다양도를 분석한 결과 식생단위 4의 종다양도 지수는 0.6976으로 가장 낮았으며, 식생단위 2의 종다양도 지수는 1.1256으로 가장 높게 나타났다. 군락간의 유사도는 식생단위 1과 4, 2와 4가 각각 0.2880과 0.3626으로 낮게 나타났으며 식생단위 1과 2, 3과 4의 군락유사성은 각각 0.5411과 0.5041로 나타나, 군락 간 구성종의 차이가 크지 않은 군락으로 판단되었다. 종간연관에 대한 Chi-square matrix와 성좌표를 각각 분석한 결과, 크게 2개의 유형으로 나뉘어졌는데 Ⅰ유형의 식물 종들은 대부분 식물사회학적으로 분류된 가문비나무군락에서 주로 출현하는 식별종과 표징종이었으며, Ⅱ유형의 식물종은 전나무군락에서 주로 출현하는 식물종으로, 비교적 습한 곳에 나타나는 종들로 나뉘어졌다. 이러한 결과는 각 수종들이 선호하는 생육환경이 비슷한 종들끼리는 정의 상관이 인정되고, 선호하는 환경이 다른 종들끼리는 부의 상관을 보이는 것으로 판단된다. In this study, for the forest vegetation classification and the quantitative analysis of the Picea jezoensis and Abies hollophylla stand, the type classification of the vegetation structure was performed with Z-M phytosociological method, and as a result, it was classified into the Picea jenoensis community and the Abies holophylla community in the community unity. The Picea jezoensis community was subdivided into the Rosa koreana group and the Acer ukurunduense group in the group unity and the Abies holophylla community was subdivided into the Acer mandshuricum group and the Lindera obtusiloba group. In the results of estimating the importance value based on the classified vegetation unity, it was deemed that the dominance of the Picea jezoensis would be continued for a while as the importance value from the tree layers of vegetation unity 1 and 2 represented relatively high with 30.73% and 20.25%. In addition, in the results of analyzing the species diversity to estimate the maturity of the community, the species diversity index of the vegetation unity 4 was the lowest with 0.6976 and that of vegetation unity 2 was the highest with 1.1256. As in the similarity between the communities, the vegetation unit 1 and 4 and the vegetation unit 2 and 4 represented low with 0.2880 and 0.3626, respectively, and the similarity between the vegetation unit 1 and 2 and between 2 and 4 represented 0.5411 and 0.5041, respectively, it was deemed that they were the communities that the difference in the composition species between the communities was not big. In the results of analyzing the Chi-square matrix and the catalog of constellations for the interspecific, they were divided mainly into two types, and type 1 plant species were mostly differential species and the characteristic species, which appeared in the Picea jezoensis community classified phytosociologically, and type II plant species were mostly the species appearing in the Abies holophylla community growing in the relatively damp places. Such results is deemed that the positive (+) correlation is recognized among the species, of which growing environments are similar, and the negative (-) correlation .represents among the species, of which preferential environments are different.

정치엘리트의 이념과 통상정책

고승연(Seung-Yon Ko) 고려대학교 일민국제관계연구원 2013 국제관계연구 Vol.18 No.1

본 연구는 지난 10년간 체결된 자유무역협정 중 가장 극심한 논란에 휩싸였던 2004년 한·칠레 FTA와 2011년 한·미 FTA 의회 비준동의안 처리과정을 비교해보면서 자유무역과 보호주의, 즉 통상정책을 둘러싼 정치엘리트 간 갈등의 양상이 어떻게 변했는지 규명하려는 데 목적이 있다. 돌이켜보면 한·칠레 FTA 비준동의안 처리 과정에서는 여·야, 진보·보수를 넘나들며 ‘농촌 지역구’의원들을 중심으로 ‘보호무역 지지 세력’의 규합이 이뤄진 반면 한·미 FTA 처리 과정에서는 당적을 중심으로 보수-진보 프레임속에 찬반이 극명하게 나뉘는 사태가 벌어졌다. 이 같은 차이가 어디에서 기인하는지 살펴보기 위해 통계청 자료와 16대 국회의원과 18대 국회의원 이념지수 자료 등을 토대로 한국의 통상정책에 정치엘리트의 이념이 미친 영향을 살펴봤다. 정량적인 방법을 통해 직·간접적으로 검증해본 결과 2004년 한·칠레 FTA 비준동의안 처리 당시까지만 해도 한국 정치과정에서 ‘과다대표’돼 있다고 여겨지던 ‘농업’의 힘은 6년 뒤 한·미 FTA 비준동의안 처리과정에서는 일정부분 약화된 것으로 나타났다. 반면 정치엘리트 간 ‘이념에 따른 자유무역협정에 대한 선호여부’는 새롭고 중요한 변수로 떠올랐다. 이는 향후 한국의 대외정책 중 통상정책에서 벌어지는 갈등을 설명하는 주요 변수로 ‘정치엘리트의 이념과 이념양극화 현상’이 자리 잡게 된다는 걸 의미한다. All Korean administrations, regardless of their political positions -progressive or conservative- have executed strong pro-free trade policy through ‘Free Trade Agreement’ for last ten years. However the processes of the ratification usually induced extreme conflicts in parliament. This article explores the changes in the conflicts over the free trade issues in Korean politics, focusing on new variables including ideologies among political elites and the party polarization. In this article, it is proved that the number of farming population known as the ‘protective force’ among the constituency, played a vital role in the FTA ratification processes. The influence on the voting behavior of congressman from the pro-protection constituency with agricultural industry was significantly weakened in Korea-US FTA ratification in 2011 whereas it has been strong in Korea-Chile FTA ratification in 2004. A new factor arises as one of the significant independent variables, which is ‘the ideologies of congressmen.’ In conclusion, the paper argues that the ideologies among political elites have strong influence in trade politics in Korea and play as the one of the most important variables to understand and explain the conflicts over free trade issues.

한국어 교사와 학습자의 이독성 요인에 대한 인식 차이

The purpose of this study is to examine the difference of recognition on the factor of Korean readability between Korean language teachers and academically-oriented foreign Korean language learners. To look into the difference of recognition on the factor of readability between the two groups, first, this author carried out a survey employing Likert’s scale, and the results of it underwent exploratory factor analysis by using SPSS 21. According to the analysis results, the difference of recognition was found between the two groups about the readability factor. Education on the readability of Korean language is distinctive from that about readability in either English or Korean because the subjects of learning are second language learners. If teachers properly understand the difference of those learners’ recognition and their distinctiveness, they will be able to provide efficient education for Korean reading.

16대 대선에서의 무당파층 특성 및 행태연구

고승연(Ko Seung-yon) 한국사회조사연구소 2004 사회연구 Vol.- No.8

이 논문은 ‘제 16대 대통령 선거관련 유권자 의식조사’를 토대로 이미 지난 16대 대선에서 40%를 넘어버린 한국의 무당파층(independent)의 특성과 행태를 분석하고 있다. 현재 한국에서 증가하고 있는 무당파층이 서구유럽에서 증가하는 무당파층과 같이 ‘적극적’인 자기규정과 높은 인지수준을 가진 집단인지 알아보고자 지수를 설정하여, 달튼(Dalton)의 분류에 따라 16대 대선에서의 무당파층을 네 유형으로 재분류하였다. 이러한 재유형화를 토대로 3장에서는, 재분류된 각 유형의 유권자들의 사회경제적, 이념적 특성 등을 추적하면서 현재 한국의 무당파층은 ‘적극적’, ‘인지적’무당파일 가능성이 높고, 앞선 재유형화가 의미가 있음을 보여주고자 하였다. 또한 4장에서는 인지적 무당파와 정치무관심층(apolitical)을 중심으로 그 선거과정과 투표에서의 행태를 분석하고 후보자 선택모형을 만들어 실제 무당파층, 특히 ‘인지적 무당파층’(apartisan)이 투표선택에 미친 영향력을 검증하였다. 이러한 결과를 토대로 현재 증가하고 있는 무당파층이 기존 정치인과 정당들에 대한 불신과 실망감에도 불구하고 자신들을 대변해 줄 대안적 정당을 찾지 못한 채 무당파가 된 유권자층일 가능성이 높다는 사실을 보여주고자 하였다. 이를 통해 지역주의 균열의 약화와 함께, 세대와 이념 등 새로운 변수들이 등장하는 현 시점에서, 유권자들은 기존 정당의 변화나 새로운 대안정당의 출현에 따라 재정렬 할 가능성이 높음을 주장하였다. The purpose of this article is to analyze the characteristics and behavior of political independents in Korea which had already exceeded 40% in the last 16th Presidential election. This work is based on ‘The Survey on Voting Behaviors in the 16th Presidential Election’. In order to find out whether the political independents are the voters who have ‘positive’ self-placement and high level of cognition, I set up an index. With the index, I re-categorized the political independents of the 16th presidential election into two types according to Dalton"s classification. Based on the new typology, I displayed the significance of the advanced typology as well as the high possibility of the present Korean political independents being ‘positive’ and ‘cognitive’ independents. This work was done by tracking the socioeconomic, ideological characteristics of each type of re-categorized voters. Then, I analyzed the behavior of the process of election and voting focusing on ‘apartisan’-cognitive political independents- and ‘apolitical’, and with a candidate choice model, I verified that political independents-especially ‘apartisan’- had an practical influence on voting. Having such results as a basis, I tried to display the high possibility that apartisans are voters who could not find alternative political party to represent themselves despite discredit and disappointment toward existing politicians and political parties. By saying so, I attempted to argue that there is a high potentiality for voters to realign themselves in accordance with change of existing political parties or advent of alternative parties at the moment where new variables such as generations and ideologies are emerging.

Background : To examine the difference between ICD-10 and The Korean standard classification of disease(oriental medicine), and to aim at improve the practical use as statistical data. It is one of the reason of disease classification. On that account we convert the many to many correspondence presenting classification of oriental medicine into many to one correspondence. Method : The study tracked out 155 patients discharged from the university hospital which is located in Gyeonggi Province and managing hospital and oriental medicine hospital from July to October this year. The period of this study was from August 1 to November 18. We compared correspondence between the two services' diagnosis(hospital services and oriental medicine hospital services) at the same time and attempted many to one correspondence classification. That is for production of statistical data. Result : We investigated the group which have had medical treatment experience of two kinds of services at the same time. The result of this investigation was that the same oriental medicine diagnosis used differently in western medicine diagnosis. 44.5% was accorded with western medicine diagnosis. Correspondence of the western medicine diagnose with the top of the Korean standard classification of disease(oriental medicine) list's western medicine diagnosis was 13.5%. For many to one correspondence classification for statistics, one western medicine diagnosis was selected for one oriental medicine diagnosis. In case of the main diagnosis(I sign) was not enough to explain oriental medicine diagnosis' characteristic, we chose multiple other diagnosis, so other diagnosis(II sign) about patient's cause of disease could be selected for supplement after we examined the patient's records. The statistics was possible with this many to one correspondence. Conclusion : The result of this study about correspondence between western medicine diagnoses and those of oriental medicine confirms that The Korean standard classification of disease(oriental medicine) is hard to be standardized with western medicine diagnosis. Therefore, according to this study, we use new many to one correspondence classification, multiple oriental medicine diagnoses with one ICD-10, which can be used by statistical data.

This study was conducted to investigate the population structure and dynamics of the Picea jezoensis stands which are located in Mt. Gyebangsan and surveyed from March to October 2012. Results showed that the diameter class distribution of P. jezoensis presented a reverse J-shaped distribution pattern with 32 trees less than 10cm DBH, 20 trees in 10~30 cm DBH, and 11 trees more than 30 cm DBH. It showed seedlings and saplings of P. jezoensis seem to prefer areas with more sun light or with open upper layer. It was also observed that P. jezoensis preferes areas with organic soils and abundant water such as areas around stumps. Also, occurrences of P. jezoensis stands were analyzed through annual mean radial growth of the trees. And the results showed that the growth naturally or artificially occurred approximately on the years 1854, 1915, 1918, 1993 and 2002 years. Most of the gap-makers were classified as standing dead type with 23 individuals (45.1%).

백두대간 조침령-신배령 구간 소나무림과 신갈나무림을 대상으로 2012년 4월부터 2013년 8월까지 영구조사구(100 m × 100 m) 설치하여 조사하였다. 총 50개소의 산림식생조사 자료를 토대로 Z-M식물사회학적 방법에 의해식생유형 분류를 수행하였던바, 최상위 수준에서 신갈나무군락군이 분류되었으며, 군락단위에서는 물푸레나무군락과까치박달군락으로 세분되었다. 물푸레나무군락은 군단위에서 소나무군과 가래나무군으로 나누어지며, 소나무군은 다시 회나무소군과 머루소군으로 분류되었고, 까치박달군락은 시닥나무군과 사스래나무군으로 각각 세분되어, 총 5개의 식생단위로 분류되었다. 식생단위별 중요치를 분석한 결과 소나무림에서 소나무와 신갈나무의 중요치가 20%이상으로 높게 나타났으나 소나무가 신갈나무보다 상대피도가 50%이상으로 가장 높게 나타났다. 종간연관 분석결과 크게 4개의 유형으로 구분되었고, 이는 식생단위의 식별종 및 표징종과 일치하는 경향이었다. 또한 소나무림의 흉고직경급별 개체 분포에서 중간직경급에서 개체수가 가장 많은 정규분포를 나타낸 소나무와 이를 제외한 다른 수종은직경이 커질수록 개체수가 감소하는 역 J자형의 분포유형을 나타내어 소나무림에서 신갈나무림으로 교체될 가능성이 크다 판단된다. 반면 신갈나무림에서는 신갈나무를 포함한 다른 수종 모두 역 J자형의 분포유형을 나타내어 신갈나무림은 당분간 안정된 상태로 지속될 것으로 판단되었다. The study was carried out to analyze vegetation structure of Pinus densiflora and Quercus mongolicaforests located in Jochimryeong to Shinbaeryeong of the Baekdudaegan mountain range. The survey for 50 plotswas conducted from April 2012 to August 2013 in the permanent plots (100 m × 100 m) using phytosociologicalanalysis. As a result, the vegetations were classified into five vegetation units. In species composition, they wereclassified into Q. mongolica community group divided into 2 community such as Fraxinus rhynchophyllacommunity and Carpinus cordata community, F. rhynchophylla community was subdivided Pinus densiflorgroup (into Euonymus sachalinensis subgroup, Vitis coignetiae subgroup) and Juglans mandshurica group. C.cordata community was subdivided Acer komarovii group and Betula ermanii group. In terms of importancevalue, P. densiflora and Q. mongolica were more than 20% respectively. P. densiflora was found to have thehighest relative coverage. Analysis of interspecific association showed four types which were coincident withdifferential species and character species on the constancy table. Based on the diameter class distribution, P.densiflora forest presented a normal distribution pattern except for other species which showed a reverse Jshapeddistribution pattern, therefore P. densiflora forest would likely be replaced by Q. mongolica forests.While in Q. mongolica forest, diameter class distribution of all species population presented a reverse J-shapeddistribution pattern, therefore Q. mongolica forest could likely remain in the future.
