Structural health monitoring is important to maintain the safety and serviceability of the structures. The displacement in the structure should be precisely and frequently monitored because it is a direct assessment index indicating its stiffness. However, no practical method has been developed to monitor such displacement precisely, particularly for high-rise buildings and long span bridges because they cannot be easily accessible. To overcome such difficult accessibility, we propose to use a LIDAR system that remotely samples the surface of an object using laser pulses and generates the coordinates of numerous points on the surface. In this study, using terrestrial LiDAR, we develop a novel displacement measuring model for structural health monitoring and perform an indoor experiment to prove its performance.

It is important to find indicators of quality nursing care to establish the excellence of nursing practice and for the development of nursing as a profession. Caring is one of the indicators which can represent professional nursing care. The purpose of this study was to develop a measurement tool of caring that could be used as an instrument for the evaluation of quality of nursing care. The Target population for the developed tool of caring is the adult patient. The mearsurement tool of caring was developed through the following steps. (1) A list of caring behaviors was made using qualitative researches on caring that has been done in Korea. (2) Caring behaviors in nurses were selected using the list of caring behaviors developed from Watson's 10 factors of caring. (3) Items for the measurement tool of caring were developed using the caring behaviors of nurses (4) Content validity of the developed items was evaluated by an expert panel. (5) The mearsurement tool of caring was developed after a pilot study (6) Internal consistency, and construct validity of the developed tool were verified. (7) The mearsurement tool of caring with the items verified for the internal consistency and construct validity was confirmed. As a result of the study, a mearsurement tool of caring, composed of 27 items with 3 factors, was developed. The Reliability coefficient of the tool was. 9578. The tool is a 5 point Likert scale. The factors of the tool and the number of items for each factor are, 1) accessibility and availablility, 15 items ; 2) emotional support and giving information, 8 items ; 3) providing a protective environment, 4 items.

Face recognition out of biometrics is considerable interesting due to high performance and accessibility in applications to security such as access control and banking service. Therefore, a study on the protocol of the performance test is an important issue to understand the art-of state and to show a direction in future works, in addtion to developing algorithms. We present a design criterion for the performance test protocol of face recognition system and show the result of experiment executed on identification and verification scenario based on PCA algorithm and XM2VTS DB

In this paper, we were implemented the application to induce correct posture by recognizing the incorrect posture of the user. Implemented system uses kinect sensors to determine the user's position information, it has been developed posture determination algorithm that can determine the four wrong posture and correct posture. In addition to PC in order to improve the user convenience and accessibility, to implement real-time monitoring application that can determine the user's position in the smartphone. For the system of performance evaluation of and promote the attitude determination experiment to target the five college students, the experimental results sensitivity and specificity of it it was found that the attitude determination performance is excellent at 0.956.

This study purports to investigate the status quo of the aged and disabled-friendly system in public health centers through the questionnaire survey and field interview. Data were collected from a total of 101 public health centers. The survey results revealed that the aged and disabled-friendly system in public health centers were not sufficient for meeting the needs of the elderly and disabled people. Based upon the study results, the following suggestions can be made to establish the aged and the disabled-friendly system in public health centers. The results of the study will make a contribution to establishing a good system for the aged and the disabled persons. In detail, they will be able to provide useful information for evaluating the status quo of the aged and the disabled-friendly system in many institutions. In addition, The results could be used as a practical strategy for improving the quality of the facilities for the aged and the disabled. In conclusion, the strategy and evaluation tool developed in the study will provide a good guide for establishing the aged and the disabled-friendly system in any institutions.

With the innovation of information technology, non-face-to-face robo advisor with high accessibility and convenience is spreading. The current robot advisor recommends appropriate investment products after understanding the investment propensity based on the structured data entered directly or indirectly by individuals. However, it is an inconvenient and obtrusive way for financial consumers to inquire or input their own subjective propensity to invest. Hence, this study proposes a way to deduce the propensity to invest in unstructured data that customers voluntarily exposed during consultation or online. Since prediction performance based on unstructured document differs according to the characteristics of text, in this study, classification algorithm optimized for the characteristic of text left by financial consumers is selected by performing prediction performance evaluation of various learning discrimination algorithms and proposed an intelligent method that automatically recommends investment products. User tests were given to MBA students. After showing the recommended investment and list of investment products, satisfaction was asked. Financial consumers' satisfaction was measured by dividing them into investment propensity and recommendation goods. The results suggest that the users high satisfaction with investment products recommended by the method proposed in this paper. The results showed that it can be applies to non-face-to-face robo advisor.

The major objective of this study was to develop recommendations for improving the design of pergola facilities located in neighborhood parks. The study employed the following methods : Physical measures and questionnaires. Physical treasures were taken of certain environmental attributes such as pergola sizes, structures, materials, etc. Questionnaires were randomly distributed to pergola users on the same day on which physical measures were scheduled. All data were collected in 1994 during the season of pergola use, September 3 to October 9. The major findings are as follows; 1. Of the 508 respondents to the question about use motivations, approximately 32% were a shady place, 18% seating arrangements suitable for conversation, 15% unconsciously, 13% a lack of bench in the park, 9% good view, and 13% other. 2. Regression analysis indicated that the best predictors of pergola user' satisfaction were : harmony with surroundings, accessibility, aesthetics of pergolas and benches, function of benches, and climbing plants. 3. Pergola design needs to be developed because pergola users were less satisfied with their pergola than with the park.

Because of the turbulent markets and the increasing demand on product quality, the application of new technology to practice is increasingly important. In case of automotive industries, they take interest in laser welding to solve these problems because laser welding has many advantages such as good accessibility, welding quality, fast welding speed and so on. To apply this technology to welding of car body, the data of laser welding are collected through lots of the experiment according to the material, geometry and layer number of welding points. Based on the experiment results and the information of product, i.e. the car side panel, the clustering of stitches for laser welding was carried out and the optimal equipments are selected through the comparison between the requirements of welding and the potential of equipments. Using these results, laser welding cell for the car side panel are configured with the concept of the digital manufacturing, which ensures maximum planning security with visualization and simulation. Finally, the optimal laser welding cell is chosen by the evaluation of alternative cells with assessment criteria.
