본 연구의 목적은 한 개인이 내린 윤리적 의사결정이 개인중심 성향이나 집단중심 성향과 같은 개인의 문화성향과 상호작용하는지를 분석하는데 있다. 이를 위해 연구 1(N=92)에서는 개인의 문화성향에 따라 다수의 이익이 부각되거나 소수의 희생이 강조되는 상황에서 윤리적 의사결정의 차이가 나타나는지를 비교하였다. 그 결과 다수의 이익이 부각되는 상황에서는 공리주의적 입장에 대한 선호가 더 컸고, 소수의 희생이 강조되는 상황에서는 의무론적 입장에 대한 선호가 더 컸다. 또한 문화성향에 따른 도덕판단 기준의 중요성을 평정하게 했을 때, 개인중심성향에서는 위해와 공정의 기준을, 집단중심성향에서는 위해, 내 집단, 공정과 권위를 모두 도덕판단의 중요한 기준으로 인식하였다. 연구 2(N=30)에서는 개인 또는 집단을 어휘판단과제를 통해 점화시킨 후, 윤리적 의사결정의 과정을 마우스추적기법을 사용하여 분석하였다. 도덕판단에서 '네'와 '아니오'의 최종적 반응으로 이어지는 경로를 마우스궤적으로 분석한 결과, 소수의 희생이 부각되면 개인점화조건에서는 집단점화조건에 비해 마우스편차와 X축 방향전환횟수가 더 컸다. 또한 내집단과 연관된 행동을 판단할 때, 개인점화조건에서는 집단점화조건보다 마우스편차가 더 큰 경향성이 나타났다. 마우스편차의 증가는 자동적인 정서의 과정을 통제하면서, 다른 대안적인 응답을 동시에 고려하는 사고과정임을 생각할 때, 이 결과는 문화성향과 갈등상황에 따라 도덕판단의 과정이 달라질 가능성을 시사한다.

자기부상열차에 있어서 분기기는 차량이 가이드레일과 접촉 없이 안전하게 노선을 변경할 수 있도록 설계돼야 한다. 특히, 별도의 안내 전자석이 없이 하나의 U-형 전자석으로 부상력과 안내력을 동시에 얻는 중저속 상전도흡인식 자기부상열차에 있어서는 분기기 통과시 안전성에 대한 검토가 요구된다. 이 방식에서는 안내력을 능동적으로 제어하지 않기 때문에 작은 곡률 반경이면서도 다수의 직선을 연결하여 곡선을 형성하는 관절형 분기기 통과시 전자석의 횡공극이 과도하게 발생하여 가이드레일과 기계적 접촉을 일으킬 수 있기 때문이다. 본 논문에서는 개발 중인 관절식 분기기에서 차량의 주행안전성 향상을 위하여 관절식 분기기의 주 설계 변수의 안전성에의 영향을 분석하는데 목적이 있다. 그를 통하여 분기기에서의 주행안전성을 향상하고자 한다. 이를 수행하기 위하여 2 량 1 편성으로 구성된 3 차원 전체차량 다물체 동역학 모델의 적용이 제안된다. 제안된 모델을 이용하여 분기기 통과시의 주행안전성척도 중의 하나의 횡공극 시뮬레이션이 이루어진다. 분석되는 설계 변수들은 단경간 거더의 길이와 굴절각, 끝단 고정궤도 중심 사이의 거리, 거더의 수량이다. 이러한 설계 변수들의 영향을 분석하여 안전성 향상을 위한 분기기 설계 방향을 제시한다.

Seven aspects of attitude toward marriage in Korea are examined to better understand present and future marriage patterns. Also, various facets of current marriage practice are compared with attitudes. The study comprises three groups of roughly 600 women each, selected by random sampling from a rural, an urban, and a semi-urban area. A carefully designed and pretested questionnaire was checked for reliability by a reinterview in a 15% subsample. The great majority of Korean women support traditional attitudes that one must or should marry. The small group who recommend that one should not marry are mostly the very young or the never married, whose attitudes still may change. However, there are important and probably predictive shifts in favor of more individual decision, especially among the better educated, the young, and the more urban. Traditional reasons for marriage such as "custom" and procreation are ranked first by a majority, but there is a large shift to more contemporary or liberal desire for companionship and love, also primarily among the better educated, the urban, the young, and the never married. The traditional attitude that parents should have the sole or major role in mate selection is still held by a bare majority; the educated, urban, young, and never married are more liberal. Only 6% opt for each of the two extremes: That the parent alone or the respondent alone should decide. The remainder prefer one of the two middle-of-the-road positions where parent and child together decide. The proportions of respondents who classed specified criteria as moat important for selecting a husband, arranging the criteria in order from traditional to contemporary were: Lineage, etc., 23%; personal attributes, 40%; health and education, 27%; and love, 10%. The changing attitudes are suggested by the fact that love was ranked first by only 3% of the poorly educated rural poulation versus 23% of urban college level and 31% of the urban never married. There has been a substantial rise in the ideal age of marriage over the past twelve or more years, but there also is evidence that the ideal age is at or near a ceiling. Knowledge about legal age of marriage is minimal; the implications of this for proposed legislation are discussed. Three-fifthes to four-fifths of all respondents married husbands of the same religious, residential, and economic backgrounds as themselves. Almost all of them married men of the same or higher educational level. These evidences of traditional influences in mate selection are contrasted with the low priority given some of those items in earlier questions on reasons for marriage and criterion for selecting husband. Contrary to the expressed attitudes as to who should select the husband, we find that marriages of the study sample were stated to be arranged by parents alone in 62%; and in another 23%, the parents made the decision but asked the respondent's views. Such arrangements were most frequent among the rural, the less educated, and the older respondents and less common in the urban and more educated. The implications of these and related findings are discussed.

Vibrational relaxation and competitive C-$H_{methyl}$ and C-$H_{ring}$ bond dissociations in vibrationally excited methylpyrazine in the collision with HF have been studied by use of classical trajectory procedures. The energy lost by the vibrationally excited methylpyrazine upon collision is not large and it increases slowly with increasing total vibrational energy content between 20,000 and 45,000 $cm^{-1}$. Above the energy content of 45,000 $cm^{-1}$, however, energy loss decreases. The temperature dependence of energy loss is negligible between 200 and 400 K, but above 45,000 $cm^{-1}$ the energy loss increases as the temperature is raised. Energy transfer to or from the excited methyl C-H bond occurs in strong collisions with HF, that is, relatively large amount of translational energy is transferred in a single step. On the other hand, energy transfer to the ring C-H bond occurs in a series of small steps. When the total energy content ET of methylpyrazine is sufficiently high, either or both C-H bonds can dissociate. The C-$H_{methyl}$ dissociation probability is higher than the C-$H_{ring}$ dissociation probability. The dissociation of the ring C-H bond is not the result of the direct intermolecular energy flow from the direct collision between the ring C-H and HF but the result of the intramolecular flow of energy from the methyl group to the ring C-H stretch.

This case study aims to explore how RDA PLA model affects the agri-SMEs' empowerment. As an agri-business management renovation program from main workshop it was conducted on March to December 2011 with agri-SMEs and extension officials nationwide by RDA. Especially, as a packaged action learning process in the model used participatory action research. This study collected data with participants observation, interviews, situational analysis and systematic review of discourse in qualitative method. For the validity and identifying empirical results, this study used statistic analysis as a mixed method. Further including various pedagogic methods and business coaching skills, this model was conducted from workshop in RDA, in turn, on-farm business coaching as follow-up, CoPs' activities, and local ATCs extension services by each actors. The dynamic process and effects of each process led some change for farmers' innovative knowledge, skills, attitude, practice and aspiration on their farm business. RDA PLA model development based on the previous practices and research, which provided a configurated picture in the holistic action learning process. In statistic research, this study focused on 279 farmers as respondents who had participated in the program. It shows that their income and benefits increased from their renovative practices on farm business. Following the sampling group, it was surveyed by four indicators - products, customer, quality and cost. The level of contribution of education on economic impact 15% is quoted from previous paper. Even in some limitations of public sector, RDA PLA model actively suggests the paradigm shift of agricultural HRD and development of alternative extension-service system.

Colbricon Superiore and Inferiore are two small adjacent high-mountain lakes located in the Paneveggio Natural Park (Italy) that offer the rare opportunity to study two iso-ecologic water environments differing only by area and volume in a ratio of 2:1 and 3:1, respectively. We took advantage of this setting to investigate phytoplankton dynamics, compare variability and productivity differences between the two basins, and assess size-dependent issues. The phytoplankton group of the Dinophyceae was chosen as the indicator organisms of ecological perturbation owing to their high sensitivity to environmental variations, as well as their acknowledged nature of versatile proxy to report global climatic changes. The study was conducted for over 10 years with fortnightly samplings. Results indicated that (a) the Dinophyceae communities in the smaller lake were significantly more resistant to changes exerted by the fluctuation of lakewater transparency and pH; and (b) the smaller lake sustained a consistently higher production with an average Dinophyceae density 1.73 fold higher than that of the larger lake. The coefficients of variation show that the chemical parameters in the smaller lake display higher time-related fluctuation while being spatially homogeneous and that such conditions correlate with a higher stability of the Dinophyceae assemblage. The use of this setting is also proposed as a model to test relationships between ecosystem production and physical stability.

Intramolecular energy flow and C-$H_{methyl}$ and C-$H_{ring}$ bond dissociations in vibrationally excited toluene in the collision with HF have been studied by use of classical trajectory procedures. The energy lost by the vibrationally excited toluene upon collision is not large and it increases slowly with increasing total vibrational energy content between 20,000 and 45,000 $cm ^{-1}$. Above the energy content of 45,000 $cm ^{-1}$, however, energy loss decreases. Furthermore, in the highly excited toluene, toluene gains energy from incident HF. The temperature dependence of energy loss is negligible between 200 and 400 K. Energy transfer to or from the excited methyl C-H bond occurs in strong collisions with HF transferring relatively large amount of its translational energy (>> $k_BT$) in a single step, whereas energy transfer to the ring C-H bond occurs in a series of small steps. When the total energy content $E_T$ of toluene is sufficiently high, either C-H bond can dissociate. The C-$H_{methyl}$ dissociation probability is higher than the C-$H_{ring}$ dissociation probability. The dissociation of the ring C-H bond is not the result of the intermolecular energy flow from the direct collision between the ring C-H and HF but the intramolecular flow of energy from the methyl group to the ring C-H stretch. The C-$H_{ring}$${\cdot}{\cdot}{\cdot}$HF interaction is not important in transferring energy and in turn bond dissociation.

This study explores the characteristics of Elizabeth Bishop's poetry in comparison with the two of her closest friends and poets, Marianne Moore and Robert Lowell. Bishop's reputation has dramatically changed since her death. In the 1970s she was "a writer's writer's writer," and admired by a small group of poets or critics. Since 1990s, however, there has been a great shift in the evaluation of her poetry, which is so called "The Elizabeth Bishop Phenomenon." It does not seem to be an easy task to examine what has driven the phenomenon, and why she used to be a minor poet or "the most honored yet most elusive of poets" but now she has a widespread recognition by the academy and beyond it. The "intrinsic qualities" of Bishop's poetry, however, can be one of the main reasons why it took several decades for Bishop to become a central figure in the literary canon. Looking into her "intrinsic qualities," this paper discusses Bishop's "The Fish," "Roosters" through the Moore-Bishop relationship, and reads Bishop's "Armadillo" and "The Monument" through the Lowell-Bishop relationship. It also deals with letters, interviews, Moore's "The Fish," and Lowell's "Skunk Hour" and "For the Union Dead" to show the Bishop's deep and complex relationships with the two poets, and more importantly their differences. Bishop's poetry is difficult, "elusive," and sometimes "enigmatic," not because her texts are full of difficult words to understand but because there are the subtle interchange between perception and meaning, "the dynamics of keen feeling," the unresolved patterns, and the transient vision under the seemingly transparent surface of the texts.

Currently, composite lining mountain tunnels in China are generally classified based on the [BQ] method for the surrounding rock grade. Increasingly, tunnel field construction is replicated indoors for scale down model tests. However, the development of analogous materials for model tests of composite lining tunnels with different surrounding rock grades is still unclear. In this study, typical Class III and V surrounding rock analogous materials and corresponding composite lining support materials were developed. The whole processes of excavation-support dynamics of the mountain tunnels were simulated. Data on the variation of deformations, contact pressures and strains on the surrounding rock were obtained. Finally, a comparative analysis between model tests and numerical simulations was performed to verify the rationality of analogous material development. The following useful conclusions were obtained by analyzing the data from the tests. The main analogous materials of Class III surrounding rock are barite powder, high-strength gypsum and quartz sand with fly ash, quartz sand, anhydrous ethanol and rosin for Class V surrounding rock. Analogous materials for rockbolts, steel arches are replaced by aluminum bar and iron bar respectively with both shotcrete and secondary lining corresponding to gypsum and water. In addition, load release rate of Class V surrounding rock should be less than Class III surrounding rock. The fenestration level had large influence on the load sharing ratio of the secondary lining, with a difference of more than 30%, while the influence of the support time was smaller. The Sharing ratios of secondary lining in Class III surrounding rock do not exceed 12%, while those of Class V surrounding rock exceed 40%. The overall difference between the results of model tests and numerical simulations is small, which verifies the feasibility of similar material development in this study.

진해만 광역해역에서 하계 식물플랑크톤의 수평적 군집 구조를 파악하기 위해서 16개 정점에서 식물플랑크톤 개체수 밀도와 환경요인을 조사하였다. 식물플랑크톤은 총 66종이 출현하였고, 전체의 80% 이상이 규조류의 점유율을 보였고, 다음으로 와편모조류와 라피도조류순으로 관찰되었다. 규조류의 우점종은 Chaetoceros affinis, C. didymus, C. pseudocurvisetus, Leptocylindrus danicus, Pseudo-nitzchia pungens, Skeletonema costatum으로 나타났고, 와편모조류는 Cochlodinium polykrikoides, Gymnodinium impudicum, Karenia mikimotoi, Prorocentrium minimum, Protoperidium bipes, Scrippsiella trochoidea로 관찰되었다. 각 정점별 식물플랑크톤의 군집구조를 바탕으로 한 MDS와 Cluster 분석에서 하계 진해만 광역해역은 크게 2그룹으로 나누어졌다. 제1그룹은 마산만 내측 정점으로 담수기원으로 높은 영양염 농도와 낮은 염분농도의 영향을 강하게 받은 곳이다. 제2그룹은 나머지 다른 외측 정점으로 구분되었다. 정준대응을 근거로 한 분석(CCA)에서도 만 내측에 우점 출현한 크기가 작은 와편모조류 K. mikimotoi, P. minimum, P. bipes, S. trochoidea와 중심목 규조류 S. costatum, C. pseudocurvisetus는 DIN (암모니윰, 질산염, 아질산염)과 상관관계를 보였다. 이러한 결과는 본 해역에서 만 내측과 외측의 정점으로 식물 플랑크톤의 군집조성이 확연히 구분되고 있고, 특히 만내측에서 높은 Chl.a농도와 더불어 식물플랑크톤의 현존량이 높게 나타나고 있다는 것을 의미한다. 결과적으로 내만의 얇은 수심에서 하계 식물플랑크톤의 대증식을 유발할 수 있었던 것은 높은 질소기원의 영양염과 수온에 의한 영향으로 사료된다.
