본 연구는 요양병원 입지전략과 내부역량의 복합적인 상호작용을 전제로 하여 재이용의도와의 관련성을 동시추정방식으로 분석하였다. 연구결과는 다음과 같다. 첫째, 재이용의도에 대한 상대적 영향력은 병원입지전략(${\beta}=0.313$) 보다 병원내부역량(${\beta}=0.490$)이 크지만 두 요인 모두 재이용의도에 통계적으로 유의미한 영향을 미친다는 점에서 선행연구 결과를 확인해 주고 있다. 둘째, 재활기능강화형 요양병원의 경우 입지전략의 중요성이 일반요양형 병원에 비해 더 중요하다는 점이 확인되었다(${\beta}=0.443$). 재활기능강화형 요양병원 개원시 특히 입지시장성, 교통인프라, 건물매력도, 의료집적성 등 입지요인에 근거하여 면밀한 준비가 선행되어야 한다는 점이 제시되고 있다. 셋째, 병원내부역량은 병원유형에 따른 조절효과는 나타나지 않았으며, 일반요양형 병원과 재활기능강화형 병원에 있어 모두 중요한 요인임이 확인되었다.

One of the common issues in large dataset analyses is to detect and construct homogeneous groups of objects in those datasets. This is typically done by some form of clustering technique. In this study, we present a divisive hierarchical clustering method for two monothetic characteristics of histogram data. Unlike classical data points, a histogram has internal variation of itself as well as location information. However, to find the optimal bipartition, existing divisive monothetic clustering methods for histogram data consider only location information as a monothetic characteristic and they cannot distinguish histograms with the same location but different internal variations. Thus, a divisive clustering method considering both location and internal variation of histograms is proposed in this study. The method has an advantage in interpreting clustering outcomes by providing binary questions for each split. The proposed clustering method is verified through a simulation study and applied to a large U.S. house property value dataset.

The causes of disease as well as the mechanisms that result in the presenting signs and symptoms of patients are basic elements in oriental medicine. The location of the disease is the region on which the cause and the nature of the disease acts. Syndrome reflects the cause of the disease and the pathological change and the location of the disease. It is customary to classify the location of the disease into two major categories. First is based on the exterior and interior and the second is based on the five internal organs. Exterior syndrome is caused by the invasion of exopathogen in skin and hair, channels and collaterals. Interior syndrome refers to the syndrome located deeply in the interior of the body such as five internal organs. The location of the disease is very important to distinguish different syndromes in the diagnosis and the treatment of a disease.

최근 몇 년 동안 병원의 과다 공급으로 인해 병원 관리가 어려워지면서 병원은 혁신적인 병원 경영을 도입하여, 고객 만족도를 높이고 있다. 이에 본 연구는 요양병원의 혁신성이 고객만족도에 미치는 영향에 대하여 병원의 내부역량과 입지전략의 매개효과를 중심으로 살펴 보았다. 연구의 대상은 서울 및 수도권 소재 요양병원 재원중인 환자 및 보호자 120명을 대상으로 선정하여 설문조사와 통계분석을 시행 하였다. 연구의 시사점은 다음과 같다. 첫째, 병원혁신성이 고객만족도에 유의한 영향을 주지 못하고 오히려 통계적으로 유의하지 않지만 부(-)의 영향을 미친다는 점에서 병원조직의 보수성 및 안정성에 대한 고객들의 기대를 확인할 수 있다. 일반기업과 달리 생명을 다루는 병원조직의 특성상 일반기업과 차별화된 병원조직 고유의 혁신성 측정도구 개발이 시급하다. 둘째, 혁신성이 내부역량과 입지전략에 미치는 영향력은 비슷했지만, 입지전략(${\beta}=0.357$)은 내부역량(${\beta}=0.283$)에 비해 고객만족도에 더 큰 영향력을 미치고 있음이 확인되었다. 요양병원의 경우 개원 시점부터 입지시장성, 교통인프라, 건물매력도, 의료집적성 등 입지요인에 근거하여 면밀한 준비가 선행되어야 한다는 점을 시사해 주고 있다. 셋째, 내부역량과 입지전략은 병원혁신성과 고객만족도 간의 관계를 완전매개하고 있음이 실증분석을 통해 확인되었다. 병원 혁신성은 유무형의 내부역량을 제고하고 있으며, 입지전략 수립을 위한 적극적 태도를 유도함으로써 고객만족도에 유의한 영향을 미치고 있음이 확인되었다.

This paper suggests the method for estimating a partial discharge (PD) location using divide of the inside transformer as a grid. The PD location is found swiftly and economically compared with the typical method detecting a PD. The reason is that the location of PD is detected in the section. The estimation of PD location is trained using the Neural Network. JavaNNS(Java Neural Network Simulator) and SNNS(Stuttgart Neural Network Simulator) are used for searching the location of PD. The simulation procedure is following, The transformer is assumed that the case is a regular hexahedron. The sensor is installed in a proper location. A section of PD location is set as a target, and training set is studied with several PD locations in the inside of the transformer. As a result of training process, the learning capability of neural network is excellent. The PD location is detected by division of internal structure of transformer and application of neural network.

Designing a reliable multicast-based network that scales to the size of a multicast group member is difficult because of the diversity of user demands. The loss inferences of internal nodes by end-to-end measurements do not require the use of complete statistics because of the use of maximum likelihood estimation. These schemes are very efficient and the inferred value converges fast to its true value. In the theoretical analysis, internal delay estimation is possible but the analysis is very complex due to the continuity property of the delay. In this paper, we propose the use of a bottleneck location estimator. This can overcome the analytical difficulty of the delay estimation using the power spectrum of the packet interarrival time as the performance metric. Both theoretical analysis and simulation results show that the proposed scheme can be used for bottleneck location inference of internal links in scalable multicasting.

This study investigated the cases of relative location, especially focused on the geomorphological situation, for the conceptualization of the location knowledge. In order to perform this study, first of all, I approached meaning of location. In this study I used the terms 'site' and 'situation'. 'Site' as used here means the location of a given place with its local internal features or resources. 'Situation' refers to the location of place as related to other places. As to location, no place exists in isolation. Therefore, it is necessary to look beyond the internal nature of the area itself to perceive its external relations with other areas. The examples of geomorphological situation were focused on the scale linkage of the examples, the interaction between elements of earth surface processes, and the method of comparative region. The regions of examples were the landscape of Mt. Hymalaya to Bengal deep sea fan, the climatical difference of continental east and west, the landscape of Mt. Geum & Sangju beach, the landscape of the south and north face of Mt. Mai., Hamjibaakgol asymmetrical valley, and the landscape of inland sea and outer sea type island.

The purpose of this study is to investigate the effect of circumferential location of local wall thinning defect on the collapse behavior of an elbow. Thus, the present study conducts three-dimensional finite element analysis on the 90-degree elbow containing a local wall thinning at intrados, crown and extrados of bend region and evaluates the collapse moment of wall thinned elbow under various thinning shapes and loading conditions. Combined internal pressure and bending moment are considered as an applied load. The internal pressure of $0\~20MPa$ and both closing and opening mode bending are employed. The results of analysis show that the reduction in collapse moment of the elbow by local wall thinning is more significant for a defect locating at crown than for a defect locating at intrados or at extrados. Also, the effect of internal pressure on the collapse moment of wall thinned elbow depends on the circumferential location of thinning defect and applied bending mode.

Objectives: Inferior alveolar nerve block (IANB) is the most frequently used treatment for mandibular molars. Successful IANB requires insertion of the dental needle near the mandibular foramen. In this study, we aimed to analyze the anatomic location of the mandibular lingula and evaluate the effects of internal oblique ridge (IOR)-guided IANB. Materials and Methods: The location of the mandibular lingula was measured using cone-beam computed tomography images of the mandibles obtained from 125 patients. We measured the distances from the occlusal plane to the lingula and from the IOR to the lingula in 250 mandibular rami. Based on the mean of these distances, alternative anesthesia was carried out on 300 patients, and the success rate of the technique was evaluated. Results: The mean vertical distance was $8.85{\pm}2.59mm$, and the mean horizontal distance was $14.68{\pm}1.44mm$. The vertical (P<0.001) and the horizontal (P<0.05) distances showed significant differences between the sex groups. The success rate of the IOR-guided technique was 97.3%. Conclusion: IANB-based location of mandibular lingula showed a high success rate. From this study, we concluded that analysis of the anatomic locations for mandibular lingula and IOR-guided IANB are useful for restorative and surgical dental procedures of the mandibular molars.

Wind-induced fluctuating internal pressures in a building with a dominant opening can be described by a second-order non-linear differential equation. However, the accuracy and efficiency of the governing equation in predicting internal pressure fluctuations depend upon two ill-defined parameters: inertial coefficient $C_I$ and loss coefficient $C_L$, since $C_I$ determines the un-damped oscillation frequency of an air slug at the opening, while $C_L$ controls the decay ratio of the fluctuating internal pressure. This study particularly focused on the value of loss coefficient and its influence factors including: opening configuration and location, internal volumes, as well as wind speed and approaching flow turbulence. A simplified formula was presented to predict loss coefficient, therefore an approximate relationship between the standard deviation of internal and external pressures can be estimated using Vickery's approach. The study shows that the loss coefficient governs the peak response of the internal pressure spectrum which, in turn, will directly influence the standard deviation of the fluctuating internal pressure. The approaching flow characteristic and opening location have a remarkable effect on the parameter $C_L$.
