Intellectual capital is the driving force for the competitive advantage and durability of the public library. This asset consists of the library members' competences, the organizational structure constructed by the members, and the interrelationships among the people sharing the same interests. These are called human capital, structural capital and social capital in the respective order. The purpose of the study was to provide foundational information for the public library's intellectual capital assessment as well as creating an experimental assessment model. It analysed the three characteristics of the capital, which generated an assessment index. In addition, it identified the relationship between the components of the intellectual capital and performance were discovered through empirical study to improve the assessment system.

This paper presents the results of investigation on tunnelling-induced ground surface settlement characteristics in water bearing ground using finite element (FE) stress-pore pressure coupled analysis. Fundamental interaction mechanism of ground and groundwater lowering was first examined and a number of influencing factors on the results of the coupled FE analysis were identified. A parametric study was then conducted on the influencing factors such as rock type, thickness of soil layer, permeability of shotcrete lining, among others. The results indicate that the tunneling-induced groundwater drawdown results in a deeper and wider settlement trough than without groundwater drawdown, and that the Error function approach does not yield satisfactory result in predicting a settlement profile. The results of analysis are summarized so that the relationship between the settlement and the influencing factors can be identified.

The purpose of this investigation was to examine the mediating effects of delinquent peers between attachment to parents, low self-control and adolescent deviant behaviors. After specifying a research model based on Gottfredson and Hirschi's general theory of crime and Hirschi's control theory of delinquency, the study analysed the model using structural equation modeling. The data for this investigation came from a sample of 2,448 Korean adolescents. The results showed the both measurement model and structural model had a good fit to the data and all paths of structural model were statistically significant. The main findings were the attachment to parents and low self-control had direct and indirect effects on adolescent deviant behaviors through delinquent peers. The implications for practical intervention and further research in the field of delinquency were discussed.

본 연구에서는 홍수시 제내지 침수로 인한 큰 인명 및 재산 피해의 가장 큰 원인이 되는 제방 붕괴과정을 제방의 침식 및 세굴이론 등 물리적 이론에 근거하여 해석하고 이를 토대로 하천제방 붕괴 모형을 개발하였다. 개발된 모형을 이용하여 하천제방 붕괴 모의를 수행하여 제내지의 2차원 침수양상을 분석하고 이를 이용하여 침수위험도를 작성하였다. 작성된 침수위험도는 제내지에 거주하는 주민들이 효율적으로 제방붕괴에 대한 대처할 수 있을 뿐만 아니라 제방붕괴로 인한 홍수재해보험 보험요율 산정시 침수위험도에 근거한 합리적 산정이 가능할 것으로 판단되었다. 본 모형의 적용 결과 홍수로 인한 제내지 침수위험도 산정을 위해 하천흐름-제방붕괴-제내지 침수해석을 연계하여 일관성 있게 모의할 수 있는 수치모형을 개발하여 실제 유역에 적용한 결과 제내지에서의 침수심, 침수면적, 하천 홍수위, 제방붕괴 폭 등이 합리적으로 계산됨을 알 수 있었다. 시간에 따른 제방 붕괴폭은 기존의 모형에서 사용하고 있는 순간적, 선형적인 붕괴가 아니라 포물선형의 붕괴가 이루어지고 있었으며 시간에 따라 붕괴폭도 합리적으로 계산되고 있음을 알 수 있었다. 제내지의 침수심을 토대로 제내지 홍수시 침수위험도 산정기법을 개발하여 위험도를 산정한 결과 하천변에 위치한 지역이 위험도가 무조건적으로 높은 것은 아니라 지형에 따라 달라질 수 있음을 나타내었다.

In this study, in order to investigate the characteristics of secondary consolidation in the soft clay ground, oedometer tests were carried out in a normally consolidated condition, and the consolidation characteristics of the soft clay ground were examined by the Finite Difference Method (FDM) based on the Elasto-Viscous model proposed by Yoshikuni. The consolidation tests adjusted the consolidation load increment ratio(${\Delta}p/p_0$) to 1.0 for the four cases with initial consolidation pressures of 0.8, 1.6, 3.2, and 6.4 kgf/$cm^2$. The long-term consolidation tests were examined by the tests that changed the load increment ratio to clarify the effect of consolidation load increment. Although the numerical analysis was delayed in the primary consolidation process, from the result of the numerical analysis of the laboratory tests, the applicability of the Elasto-Viscous model was verified from the agreement of the secondary consolidation process. Based on the developing of model ground consist of general soft clay, influences of consoliation parameters on the consolidation characteristics were studied by the numerical analysis.

A method to design a critical height of embankments is presented so as to mobilize fully soil arching in pile-supported embankments. The behavior of the load transfer of embankment weights on pile cap beams was investigated by a series of model tests performed on pile-supported embankments with relatively wide space between cap beams. The model tests explained that the behavior of the load transfer depended very much on the height of embankments, because soil arching could be mobilized in pile-supported embankments only under enough high embankments. The measured vertical loads on cap beams coincided with the predicted ones estimated by the theoretical equations, which have been presented in the previous studies on the basis of load transfer mechanisms according to either the punching shear failure mode during low filling stage or the soil arching failure mode during high filling stage. The mechanism of the load transfer was shifted beyond a critical height of embankment from the punching shear mechanism to the soil arching mechanism. Therefore, in order to mobilize soil arching in pile-supported embankments, the embankments should be designed at least higher than the critical height. A theoretical equation to estimate the critical height could be derived by equalizing the vertical loads estimated by the load transfer mechanisms on the basis of both the punching shear and the soil arching. The derived theoretical equation could predict very well the experimental critical height of embankment.

In current slope stability analysis techniques, slope stability is evaluated based on the saturated-soil theory. However, soil-water characteristics change frequently depending on the climate. Therefore, because the saturated soil theory has limitations, the application of the unsaturated soil theory is necessary for slope stability. It is also important to evaluate the engineering properties of unsaturated soil because the capillary absorption capacity is reduced due to heavy rain, thereby causing a reduction in slope stability. In this study, soil-water characteristic tests were performed using four samples with different fine contents (0%, 10%, 20%, and 30%) using granite-weathered soil in domestic production areas. In particular, to consider the previously conducted drying process as well as the evaluation of stability due to heavy rain on the actual slope, a wetting process was conducted, in which the water content was increased. In addition, the van Genuchten (1980) model, which is the most consistent theoretical equation for the experiment, was used with various theoretical equations, and the parameters were analyzed according to the fine content of the granite-weathered soil for the drying and wetting processes.

This study mainly focused on the subsurface settlement due to shallow and deep tunneling in sandy ground. In order to figure out theoretical deformation patterns in association with the ground loss during the progress of tunneling, laboratory model tests using aluminum rods and finite element analyses using the CRISP program were carried out. As a result of comparison between the model test and the finite element analysis, the similar deformation patterns were found. In addition, it was identified that the most K values obtained from both the FEA and the model tests were distributed between Dyer et al. (1996) and Moh et al. (1996) of the field observation data. Based on the model test data, the linear equation of K for the sandy soil could be obtained.
