Objective: The purpose of this study is to investigate the past history of the patients with peripheral type nerve palalysis. Methods: We examined the age, sex, region, month, season, past disease and cause of 692(343 male, 349 female) patients with peripheral type nerve palalysis who visited Dept. of Acupuncture and Moxibustion, Bundang Oriental Medicine Hospital, Dongguk University, from 2001-10-1 to 2004-9-30. Results: 420 patiens(60.7$\%$) were in the age between 30-59. The region, sex, and seasonal distribution didn't have a remarkable contrasts. In the past disease, Hypertension(14.5$\%$), Diabets mellitus(9.2$\%$), Gastric diseases(3.9$\%$) and Live diseases(3.8$\%$) were investigated highly than other diseases. In the distribution of cause, fatigue(36.3$\%$), unknown(34.8$\%$), stress(19.2$\%$) cold exposure(12.1$\%$) were investigated highly than other causes.

Purpose: Online meeting is chosen instead of face-to-face conferences as a solution that ensures both effectiveness and legality during times of strong epidemic outbreaks. In the current period, managers can have different types of meeting options for information distribution. This study has examined the effect of past behavior on the managers' intention of organizing online meetings. Research design, data and methodology: Data were collected from a survey with 475 managers and put into SmartPLS 4.0 for analysis. Partial least squares structural equation modeling (PLS-SEM) was employed to test relationships in the research model. Results: The findings indicated that past behavior plays the most critical role in explaining the organizing online meeting intention of managers, followed by attitude and subjective norms. Meanwhile, the perceived behavioral control factor has absolutely no effect on intention in the context of this study. Notably, attitude and subjective norms also remarkably mediated the impact of past behavior on managers' intention. Conclusions: This study has added to the understanding of the meeting organization behavior of managers. Even if the epidemic is under control, the administrators should still organize some meetings in the form of online because it will affect the social perceptions of future behavior and behavioral intention.

In this paper, we study the long-time dynamical behavior for the extensible suspension bridge equations with past history. We prove the existence of the global attractors by using the contraction function method. Furthermore, the regularity of global attractor is achieved.

The Main concern of this thesis is on the possibility to apply Hermeneutics to architectural history, with a view point that the past architecture can be seen as a text, this study analyse the relationship between the past building and interpreter, the epistenological tool for interpretation and historian. After reviewing the characteristics of architectural history with regard to text theory, this study can lead to the conclusion that the interpretation of past architecture can be defired as dynamic dialogue which depend upon the time.

Moving objects are spatio-temporal data that change their location or shape continuously over time. Generally, if continuously moving objects are managed by a conventional database management system, the system cannot properly process the past and future location which is not stored in the database. Up to now, for the purpose of location tracking which is not stored, the linear interpolation to estimate the past location has been usually used. It is suitable for the moving objects on linear route, not curved route. In this paper, we propose a past location tracking algorithm for a moving object on curved routes, and also suggest a future location tracking algorithm using some past location information. We found that the proposed location tracking algorithm has higher accuracy than the linear interpolation function.

When the past architecture is renovated, the important point is to approach from social and historical point of view. In Europe, there are many cultural and architectural hereditaments by backed-up ancient history and are usually happened modernistic applications of these architectures. Specially, when the past architecture is renovated, this study is focused on cases of museum and gallery which the people are approachable by me. I studied how to expressed the durability and to distinguish the design characteristics that is connected with the past from the European cases at modernistic point of time. The design characteristics are discovered two kinds. The first is 'consideration of the past architecture' and the second is 'consideration of the present age'. The results of this study are as follows； 1. The component reanalysis 2. The use of material 3. The introduction of symbolic elements 4. The Change of function

This study investigated the Present traditional Korean farmhousing and Past housing (from 1928~1956) based on a survey of 23 Korean women from Kyongki Province. It was primarily concerned with a Comparison of the present and past housing ; the size and plan of the house and finishing materials of Anbang(The masters bedroom : ondol) and the kind of furniture. lighting and heating in the Anbang. I was also interested in identifying the socio-demographic and physical variables that influenced the housing, past and Present. Bibliographical studios. cultural approaches and field surveys with tape recordings and questionnaires were used to collect the data. The results showed that the former Housing(averag ; 54 years ago) was very poor. Most homes lacked sufficient space. furniture and experienced a shortage of fuel. The most decisive difference from the present was the large family size. It would be beneficial to make a similar study in both the southern and northern regions of Korea.

Numerical simulation of flow past two-dimensional hill and valley is presented. Application of three turbulence models - the standard and modified (Kato-Launder) $k-{\varepsilon}$ models and standard $k-{\omega}$ model - is discussed. The computational methodology is briefly described. The mean velocity and turbulence intensity profiles, obtained from numerical simulations of flow past the hill, are compared with the experimental data acquired in a boundary-layer wind tunnel at Colorado State University. The mean velocity, turbulence kinetic energy and Reynolds shear stress profiles from numerical simulations of flow past the valley are compared with published experimental data. Overall, the results of simulations employing the standard $k-{\varepsilon}$ model were found to be in a better agreement with the experimental data than those obtained using the modified $k-{\varepsilon}$ model and the $k-{\omega}$ model.

Location prediction has been successfully utilized to provide high quality of location-based services to customers in many applications. In its usual form, the conventional type of location prediction is to predict future locations based on user's past movement history. However, as location prediction needs are expanded into much complicated cases, it becomes necessary quite frequently to make inference on the locations that target user visited in the past. Typical cases include the identification of locations that infectious disease carriers may have visited before, and crime suspects may have dropped by on a certain day at a specific time-band. Therefore, primary goal of this study is to predict locations that users visited in the past. Information used for this purpose include user's demographic information and movement histories. Data mining classifiers such as Bayesian network, neural network, support vector machine, decision tree were adopted to analyze 6868 contextual dataset and compare classifiers' performance. Results show that general Bayesian network is the most robust classifier.
