The purpose of this study was to obtain the information of the home treatment state for children with delayed development and to identify stress and coping pattern in mothers of the children. Data were collected from 211 mothers of delayed developmental children(DDC) by means of structured questionnaires. The results of this study were that in the home treatment mothers had technical insufficiencies to treat their children. so they had a difficulties in treating their children at home. But the home treatment were effective and mothers were assisted by their family and others in their treatment. The mothers had stress by anxiety of prognosis. hurts, responsibility, technical insufficiencies and negligent in housework. And acquisition of home treatment technique, the existence of assistant, and emotion in treatment also influenced on stress in the mother. The coping pattern in the stress were regular medical examination. communication with medical team and other mothers with DDC, faith of recovery and treatment. confidence in home treatment, family coorperation. and leisure time without concern for treatment. The younger mother received the more help from other mothers with DDC. And the mothers with severe, complex DDC had the more help from faith of recovery. Regular medical examination and faith of recovery were helpful coping pattern in mothers who had no treatment skill. Confidence in family coorperation and leisure time without concern for treatment were particularly helpful in mothers whose treatment duration is longer, and home treatment was not effective.

Detection of anomalous events from video streams is a challenging problem in many video surveillance applications. One such application that has received significant attention from the computer vision community is traffic video surveillance. In this paper, a Lossy Count based Sequential Temporal Pattern mining approach (LC-STP) is proposed for detecting spatio-temporal abnormal events (such as a traffic violation at junction) from sequences of video streams. The proposed approach relies mainly on spatial abstractions of each object, mining frequent temporal patterns in a sequence of video frames to form a regular temporal pattern. In order to detect each object in every frame, the input video is first pre-processed by applying Gaussian Mixture Models. After the detection of foreground objects, the tracking is carried out using block motion estimation by the three-step search method. The primitive events of the object are represented by assigning spatial and temporal symbols corresponding to their location and time information. These primitive events are analyzed to form a temporal pattern in a sequence of video frames, representing temporal relation between various object's primitive events. This is repeated for each window of sequences, and the support for temporal sequence is obtained based on LC-STP to discover regular patterns of normal events. Events deviating from these patterns are identified as anomalies. Unlike the traditional frequent item set mining methods, the proposed method generates maximal frequent patterns without candidate generation. Furthermore, experimental results show that the proposed method performs well and can detect video anomalies in real traffic video data.

Through a questionnaire survey of 607 respondents over 20 years old currently residing in Seoul, general conditions, items and amount of daily diet, preference of dining-out and instant food, and concern for health were surveyed and the results are as follows. A large portion of respondents, at 36.2% of all respondents, were 20 years old, 57.7% of them graduated from high school or over, and most of them(61.9%) were over middle-class level of living standard. More than half (50.9%) of whom paid less than 10% for dining-out took breakfast as a rule, and 38.3% of whom regularly took meals and 37.3% of them took their regular daily routines. But among whom spent more than 31% for dining-out 46.2% of them took snacks between meals every day. Also, among whom spent more then 31% for dining-out, about 25.6% of them usually dined out every day. On concerns for health, among whom spent less than 10% of dining-out expense, 53.9% of them took exercise almost every day and 32.8% for 30 minutes, and 34.6% of them were generally healthy and 67.5% of them had normal blood pressure. But among whom spent more than 31% for dining-out expenses, 10.3% of them were not healthy, 15.4% had higher blood pressure and 20.5% had lower blood pressure, thus those portion were relatively higher compared with the former group. From those research results, therefore, group who spent lower dining-out expenses were older people with lower educational and living level but regularly took breakfast and exercise. Thus, their daily schedules were routine and took regular meals with healthy condition. The group with lower dining-out expense took right food pattern and kept healthy condition, and, therefore, it implied that dining-out gave significant influence to food pattern of grown-ups. Therefore, nutrition education for grown-ups might be necessary again and our foods as a diet should be re-evaluated and re-highlighted. To formulate the practical nutrition education in early childhood, practical, systematic, and continuous nutrition education might be required and effective and multidimensional education programs should be developed. In addition, various menus of breakfast with diverse materials, wide range of nutrition, and being convenient and time-saving must be studied in the near future.

본 논문은 무선 셀룰러 시스템 환경에서 일정구간을 이동하는 지하철, 기차와 같이 규칙적인 이동 패턴을 보이는 운송 매체에 탑승한 사용자들의 이동성을 지원하기 위해 PGLT(Profile­based Group Location Tracking) 기법을 제안한다. 최근 무선 통신 기술의 발전으로 인한 이동 사용자(Mobile Terminal, MT)의 급증은 시그널링 트래픽의 증가로 이어져 결국 위치 관리 비용까지 높아지게 되었다. MT들이 동시에 새로운 등록 영역으로 이동할 때 GLT(Group Location Tracking) 위치 관리 기법에서는 기존 IS­41의 각 사용자들의 개별적인 위치 갱신 요청 대신에 그룹을 이용한 위치 갱신 요청으로써 위치 관리 비용을 줄였다. 그러나 본 논문에서 제안하는 PGLT 기법은 GLT 기법을 향상시킨 기법으로서, 사용자들의 규칙적인 이동 패턴 특성을 살린 프로파일 정보를 이용하여 그룹에 대한 위치 갱신 비용까지도 줄일 수 있다. MSRP­VLR(Mobility Scheduler on Regular Path)과 RMB(Regular path Movement Buffer)를 이용하여 일정구간을 이동하는 TV(Transportation Vehicle)가 위치 갱신 요청을 하면, MSRP­VLR은 이동 경로에 대한 프로파일 정보를 보내어 TV의 RMB에 저장함으로써 그 경로를 이동 시 그룹에 대한 위치 갱신 요청을 할 필요가 없게 된다. 따라서 PGLT 기법은 GLT 기법의 그룹 위치 갱신 비용을 줄임으로써 일정구간을 이동하는 TV에 탑승한 많은 사용자들에 대한 위치 관리 비용을 현저히 줄일 수 있다.

This paper discusses 2D lattice models of beams for simulating the fracture of brittle materials. A simulation of an experiment on a concrete beam subjected to bending, in which two overlapping cracks occur, is used to study the effect of individual beam characteristics and different arrangements of the beams in the overall lattice. It was found that any regular orientation of the beams influences the resulting crack patterns. Methods to implement a wide range of Poisson's ratios are also developed, and the use of the lattice to study arbitrary micro-structures is outlined. The crack patterns that are obtained with lattice are in good agreement with the experimental results. Also, numerical simulations of the tests were performed by means of a lattice model, and non-integer dimensions were measured on the predicted lattice damage patterns.

In this work, the movement pattern of a floating breakwater is numerically analyzed using Smoothed Particle Hydrodynamic (SPH) method as a Lagrangian scheme. At the seaside, the regular incident waves with varying height and period were considered as the dynamic free surface boundary conditions. The smooth and impermeable beach slope was defined as the bottom boundary condition. The effects of various boundary conditions such as incident wave characteristics, beach slope, and water depth on the movement of the floating body were studied. The numerical results are in good agreement with the available experimental data in the literature The results of the movement of the floating body were used to determine the transmitted wave height at the corresponding boundary conditions.

Purpose: The purpose of this study was to investigate the degree and pattern of knowledge management process, and to identify the relationship between knowledge management process and organizational effectiveness in clinical nurses. Method: Participants were 665 regular clinical nurses who had worked for over 1 year in general units of 9 tertiary medical hospitals including 2 national university hospitals, 5 university hospitals, and 2 hospitals founded by business enterprises. Data were collected from March to May 2003 through questionnaires. Four structured instruments were used to collect the data: Knowledge Management Process Scale(Jeong, Lee, Lee, & Kim, 2003), cCommitment Questionnaire(Mowday, Steers, & Porter, 1979), General Satisfaction Scale(CooK, Hepworth, Wall, & Warr, 1981), and one for general characteristics. The data were analyzed using factor analysis, reliability analysis, descriptive analysis, cluster analysis, one-way ANOVA, Scheffe test, correlation analysis with the SPSS for Windows 10.0 program. Result: 1) The average score for knowledge management process in nurses was $3.08{\pm}.54$ on a 5-point Likert scale. In order from highest mean score, the elements of knowledge management process, were Knowledge $Utilization(3.35{\pm}.57)$, Knowledge $Sharing(3.07{\pm}.58)$, Knowledge $Creation(2.99{\pm}.63)$, and Knowledge $Storage(2.91{\pm}.82)$. 2) Four knowledge management patterns for nurses, which were derived from cluster analysis, were inactivate pattern, delayed pattern, activate pattern, and high-activate pattern of knowledge management. 3) The degree of knowledge management process activation and 4 elements of knowledge management process, Knowledge Creation, Knowledge Storage, Knowledge Sharing, and Knowledge Utilization, were significantly correlated with nurses' organizational commitment and job satisfaction(p=.000). 4) The nurses' organizational commitment and job satisfaction showed significant differences according to the knowledge management patterns derived from cluster analysis of high-activate pattern, activate pattern, delayed pattern, inactivate pattern(p=.000). Conclusion: These results suggest that there are four knowledge management patterns for nurses, and knowledge management process positively affects the nurses' organizational commitment and job satisfaction. From the above findings, knowledge management process is empirically verified as a useful and effective method to increase organizational effectiveness, and develop the organization.

The vortex-drift pattern over a girder surface, actually demonstrating the complex fluid-structure interactions between the structure and surrounding flow, is strongly correlated with the VIVs but has still not been elucidated and may be useful for modeling VIVs. The complex fluid-structure interactions between the structure and surrounding flow are considerably simplified in constructing a vortex model to describe the vortex-drift pattern characterized by the ratio of the vortex-drift velocity to the oncoming flow velocity, considering the aerodynamic work. A spring-suspended sectional model (SSSM) is used to measure the pressure in wind tunnel tests, and the aerodynamic parameters for a typical streamlined closed-box girder are obtained from the spatial distribution of the phase lags between the distributed aerodynamic forces at each pressure point and the vortex-excited forces (VEFs). The results show that the ratio of the vortex-drift velocity to the oncoming flow velocity is inversely proportional to the vibration amplitude in the lock-in region and therefore attributed to the "lock-in" phenomena of the VIVs. Installing spoilers on handrails can destroy the regular vortex-drift pattern along the girder surface and thus suppress vertical VIVs.
