스티븐스판사는 이 사건에 대한 법원의 의견을 제시하였다. 비록 브레난판사와 오커너판사가 별도의 의견을 제시하였으나, 반대의견은 없었다. 스티븐스판사의 의견과 브레난판사는 끼워팔기를 평가함에 있어서 당연위법의 접근방법을 유지하기 위하여 노력하였다. 다음의 의견은 법적으로는 동일한 결론에 도달하였으나, 그 방법은 서로 다르다.

This paper describes user context awareness system, which is one of the most essential technologies in various application services of ubiquitous computing. The proposed system used two-axial accelerometer, embedded in $SenseWear^{(R)}$ PRO2 Armband (BodyMedia). It was worn on the right upper arm of the experiment subjects. Using this data, PC-based fuzzy inference system was realized to distinguish human motion states, such as, tying, sitting, walking and running. The recognition rates of human motion states were 100 %, 98.64 %, 99.27 % and 100 % respectively for tying, sitting, walking and running.

Modular construction is an emerging technology to accommodate the increasing restrictions in terms of construction period, energy efficiency and environmental impacts, since each structural module is prefabricated offsite beforehand and assembled onsite using industrialized techniques. However, some innate structural drawbacks of this innovative method are also distinct, such as connection tying inaccessibility, column instability and system robustness. This study aims to explore the theoretical and numerical stability analysis of a tenon-connected square hollow section (SHS) steel column to address the tying and stability issue in modular construction. Due to the excellent performance of composite structures in fire resistance and buckling prevention, concrete-filled steel tube (CFST) columns are also taken into account in the analysis to evaluate the feasibility of adopting composite sections in modular buildings. Characteristic equations with three variables, i.e., the length ratio, the bending stiffness ratio and the rotational stiffness ratio, are generated from the fourth-order governing differential equations. The rotational stiffness ratio is recognized as the most significant factor, with interval analysis conducted for its mechanical significance and domain. Numerical analysis using ABAQUS is conducted for validation of characteristic equations. Recommendations and instructions in predicting the buckling performance of both SHS and CFST columns are then proposed.

The aim of this study was to investigate the effect of parity and postpartum day on the behavior of nursing sows and their suckling piglets. Total 36 Landrace or Yorkshire sows(range of parity: 1 to 8) and their litters(range of litter size: 11 to 13 piglets) were assigned with sow's parity($1{\sim}2,\;3{\sim}4$ and 5 or more) and sow's postpartum days(day 1, 7, 14 and 21). The sows were housed in farrowing crates($0.6{\times}2.1m$) located in pens($2.4{\times}1.8m$) with totally perforated flooring. The sows and piglets were conventionally managed. The sows and their piglets behaviors were recorded during the 24 hour period at 1, 7, 14 and 21 days of postpartum. The obtained results from this study were as follows; 1. All the nursing sows in both group made attempts for lateral tying more than for other behaviors for whole days. The order of behavioral frequency at 1 and 3 weeks postpartum according the days of postpartum of sows was lateral tying, ventral lying, standing, sitting, feeding and drinking. The nursing sows at day 1 postpartum spent more time on sitting and standing than the sows at day 7 or more postpartum. 2. The parity of sows did not affected the lateral tying and sitting behavior of nursing sows, however the ventral tying are lowed in $1{\sim}2$ parity of sow group than the other parity group. Standing, feeding and drinking behavior of sows was not showed at any trends according to the sow's parity. 3. In the behaviors of suckling piglets, lying was increased and unsuccessful suckling was decreased until 21 days postpartum. Compared to the 7, 14 and 21 day postpartum, piglets at the 1 day postpartum spent less time for lying and walking, whereas they spent much more time for unsuccessful suckling. 4. According th the sow's parity, their piglets tying and unsuccessful suckling was lowed in $1{\sim}2$ parity sow group, however more than 3 parity sow's piglets behavior are not affected.

When two objects are tying in the same visual direction there occurs abrupt depth change between two objects, which is against the assumption of the computational model for stereopsis on the surfaces in a natural scene. For this reason, this stimulus configuration is popularly used in the studies for the effectiveness of the constraints employed in the computational model. Contrary to the results from two nails (or objects) tying in the same visual direction, the two different surfaces from random-dot stereogram (RDS) in the same situation can be seen simultaneously in the different depth. The seemingly contradictory results between two situations my reflect the different strategies imposed by binocular mechanism for each situation during binocular matching process. Otherwise, the surfaces tying in the same visual direction is not equivalent situation to two objects tying in the same visual direction with regards to matching process. In order to examine above possibilities, the stereoscopic depth of the surface was measured after manipulating the visual direction of the surface elements. The visual direction of each dot pair from different surfaces in RDS (in Experiment 1) or the visual direction of line (hawing rectangle with regard to that of the vertical line (in Experiment 2) was manipulated. The stereoscopic depth of the surface was found to be varied depending on visual direction of the surface elements in both RDS and line hawing stimulus. Similar to the results from two nails situation depth of the surface was greatly reduced when each surface element was tying in the same visual direction as that of the other surface element or the other object. These results suggest that binocular mechanism imposes no different strategy in resolving correspondence problem in both two objects and two surfaces situation. And the results were discussed in the context of usefulness of the constraints employed in the computational model for stereopsis.

Every few years the low-tying coastal plains of Bangladesh are seriously flooded by storm surges, in which fierce cyclones develop in the Bay of Bengal and then move towards the coast, pushing large masses of sea water onto the land. The coastal areas are densely populated and the combination of high winds and deep floods invariably kills thousands of people. (omitted)

Beaches and low-tying coastal areas have been seriously eroding at many places along the global coastlines during the past century. The coastal erosion problem during the next century is said to be potentially worse due to the sea-level rise by global warming. Coastal erosion, whatever the time scale is, is the result as a response of land to oceanic, atmospheric, and human impacts. (omitted)

본 논문에서는 공유 모델링의 대표적인 방법인 결정트리 기반 상태공유 모델을 기반으로 하여 그 출력 확률 분포의 혼합 가우시안 수를 줄임으로써 모델을 최적화하고자 하였다. 결정트리 기반의 상태공유 모델링은 일반적인 방법을 따랐으며 혼합 가우시안 수를 늘려 인식률이 최대가 되는 지점에서 혼합 가우시안을 클러스터링하여 그 수를 줄였다. 클러스터링 시에 필요한 거리 측정 방법이나 가까운 두 가우시안의 합성 방법을 여러 기법을 실험하였다. 이때 인식률은 클러스터링 이전인 97.2%를 유지하였으며 총 혼합 가우시안의 감소율은 1.0%를 보임으로써 모델을 최적화할 수 있었다.

We synthesize the recent work done on conditionally defined Lucas and Fibonacci numbers, tying together various definitions and results generalizing the linear recurrence relation. Allowing for any initial conditions, we determine the generating function and a Binet-like formula for the general sequence, in both the positive and negative directions, as well as relations among various sequence pairs. We also determine conditions for periodicity of these sequences and graph some recurrent figures in Python.
