Cavitating fluid sea ice model of Plato and Hibler (1992) is applied to the Southern Ocean with an idealized, circular Antarctica. Using climatological atmospheric forcing fields averaged in the zonal direction, we show that oceanic heat flux and ice velocity have major effects on the seasonal change of ice edge, as other studies showed. In our model results, there appears a zone of free drift that contains a polynya zone. Thermodynamic forcing functions make dominant contributions to daily increments of ice thickness and compactness, except the zones of ice edge and polynya. The dominant contributions are also shown in distributions of the temperature on ice surface and several to terms in surface heat balance equation, and are also confirmed by those obtained from the thermodynamic-only model with the different locations of ice edge.

For the past decade, supported by the Korean government, the solar and space weather group of Korea Astronomy and Space Science Institute (KASI) has been researching towards the prevention of hazardous effects on Korean satellites, the stability of wireless telecommunications, and the safety of polar route aviation. So far, we have expanded the ground observation system, made space data more accessible, developed more advanced models for space weather forecasting, from which we have been providing forecasting services to a satisfied domestic clientele. Alongside that, we have continued our research on solar activities and the Sun-Earth connection. In this talk, I will summarize our contributions to space weather over the past 10 years and discuss future plans for next decade.

This study explored moderating effects of parental rejection on the relationship between corporal punishment and psychological maladjustment of 348 5th and 6th grade elementary school children. Participants responded in school to the Physical Punishment Questionnaire(Rohner, 1997), Parental Acceptance-Rejection Questionnaire(Rohner, 1991), and the Personality Assessment Questionnaire(Rohner, 1991). Results of regression analyses showed that both parental punishment and parental rejection made significant contributions to children's psychological maladjustment. Hierarchical regression analyses showed that parental punishment made significant contributions to maladjustment only when it was influenced by perceived maternal rejection. Conclusions were that apparent relations between parental punishment and children's psychological maladjustment were moderated by children's perceptions of maternal rejection.

This article investigated the lives and careers of three great librarians in India, USA, and Korea: S. R. Ranganathan, Melvil Dewey, and Bong-Suk Park, respectively. It also explored their influences and contributions. Their births and early years, and marriage; college years; commitment toward librarianship and careers; achievements in other areas; personalities; and commemorative activities, among others, were analyzed. Their contributions to librarianship and library community in the general theory of library science, professional education, classification and cataloging, library administration and management, and library associations and library movement were also investigated. Special focus was on Bong-Suk Park, with a special regard to his unrealized dream for the Korean library community as well as insufficient estimation related to him and his achievements.

If reinforced concrete beam exists crack, ultimate shear transfer strength and shear hardness of section with crack substantially decrease. In this study , five model beams were designed for the objective of clarfying contributions of three shear resistant elements : the compression zone of concrete, dowel action of tension reinforcement, aggregate interlock across cracks, The shear force carried by each resistant element was calculated from the detailed strain data on the contributions to the shear capacity of beams of the shear forces carried by the other three resistant element. The test result follows : 1) Compression zone of concrete (C)-56.2%, 2) Dowel action of tension reinforcement (D)-18.0%, 3)Aggregate Interlock(A)-25.8%.

This paper is aimed at the investigation of pragmatic contributions to the identification of explicatures. An explicature is the result of fleshing out the semantic representation of an utterance. The basic assumption of the paper is that the process of the developing the semantic representation into an explicature depends heavily on contextual information. Therefore, we are concerned with the way in which hearers use contextual information to flesh rut or develop the semantic representation of an utterance. The identification of explicatures includes both the recovery of the proposition expressed and the recovery of what we called higher-level explicatures. There are three subtasks involved in the recovery of the proposition expressed: reference assignment disambiguation and enrichment On the other hand, there are two subtasks involved in the recovery of higher-level explicatures: attitudes and speech acts.

An electric field due to point dipole within conductor-backed thin dielectric layer above the earth is calculated by using saddle point method When the dielectric layer is thin enough to support a cutoff mdoe, we show that the field may be approximated by sum of contributions of branch points of TE mode and poles of tM mode and that the branch points and poles contributions are interpreted as an evanescent lateral waves and leaky waves, respectively.

This study examines the relationships between desired recreation experiences recreational context and environmental attributes that influence the choice of national park in which to recreate. Eight hundred and five visitors in three national park in which to recreate. Eight hundred and five visitors in three national parks were surveyed. Seven recreational experience domains and four homogeneous groups were identified. The contributions of environmental attributes homogeneous groups were identified. The contributions of environmental attributes to the choice of national park were found to differ among four groups, and across recreational context such as past experience, membership, and the length of visit. The implications for national park management were discussed.

The phenomenon of increasing aging population is one of the crucial social and economic issues in these day. In this paper, drawn from the industrial application cases and relevant literatures, we present the typology of ICT convergent applications targeted for silver generation, referred as silver ICT. Subsequently, the contributional value of ICT as the enabling technology is estimated. We firstly conduct keyword search to collect currently used silver ICT applications. Secondly, drawn from the social welfare literature, we organize distinctive needs of the silver generations. Then, on the basis of task technology fit framework, typology of ICT enabled silver applications is organized through the fit of ICT in the sense of fulfilling those silver needs. Finally, using the industry input-output table figures, potential ICT contributions for silver ICT are estimated. The proposed silver ICT typology and ICT contributions provides useful insights for further research in the area of ICT convergence and silver market research.

The data set was collected on fifty-eight different days with a 24-h sampling period from October 27, 1995 through August 25, 1996. From the chemical mass balance (CMB) analysis of $PM_{2.5}$ in the Chongju area, the contributions from soil, gasoline, diesel, light and heavy oil combustion were 2.6%, 15.4%, 9.0%, 28.8% and 1.5%, respectively. Residual $NO_{3}^{-}$), residual $SO_{4}^{2-}$ and residual OC, possibly formed in the atmosphere. represented additional 8.0, 10.2, and 1.6% of the $PM_{2.5}$, respectively. Other unidentified sources constituted the remaining 22.9%. From the CMB analysis, the $PM_{2.5}$ source contribution for fall, winter, spring and summer were 92, 76.8, 77.5 and 59.2%, respectively.
