The purpose of this study is to analyze the effects of local community resident-participation factor on the local community resident-participation determinant and the formation of social capital. Accordingly, questionnaire method was used for 389 residents in A-dong that have participated in community building projects in Busan region to analyze their demographical factor & residential area factor and local community resident-participation factors of satisfaction of neighborhood environment, satisfaction of administrative support, local attachment and neighbor connectedness effects. The analysis results showed that first, the satisfaction of outside support and neighbor connectedness were found to be the main factors. Second, the satisfaction of outside support, local attachment and neighbor connectedness showed meaningful effects in the state where these factors were controlled. Third, the effects of each social capital sub-element were verified and the results showed that while trust and network had meaningful effects on satisfaction of outside support, local attachment and neighbor connectedness effects, norm of reciprocity showed meaningful effects on gender, house ownership status, local attachment and neighbor connectedness, thereby showing differences. Based on these study findings, implications and suggestions were presented.

Ridge partial least squares regression (RPLS) is a regression method which can be obtained by combining ridge regression and partial least squares regression and is intended to provide better predictive ability and less sensitive to overfitting. In this paper, explicit expressions for the shrinkage factor of RPLS are developed. The structure of the shrinkage factor is explored and compared with those of other biased regression methods, such as ridge regression, principal component regression, ridge principal component regression, and partial least squares regression using a near infrared data set.

This study was done to develope a computer program for the evaluation of quality of nurisng care. Because the professional nursing care should be evaluated consistantly, computer program for the measurement of quality of nursing care is necessary for the effective and efficient management of nursing quality. In this study, a computer program for gastrointestinal surgery patients was developed as a module. Visual basic 4.0 was used as a basic program for the development of this program, and Access 7.0 was used for the data base construction of the program. The systems of evaluation criteria were hierarchical. and the titles of the hierarchical criteria were evaluation area-evaluation item-indicator. Each evaluation area contained several items and each evaluation item contained several indicators. The numbers of the evaluation criteria for gastrointestinal surgery patients were 7 evaluation areas, 32 evaluation items. and 71 indicators. Content validity of the evaluation criteria(in this case, 32 evaluation items) was .95. Scoring could be possible with the evaluation items. For the scoring types of this program were two. norm-referenced type(option 1) and criterion-referenced type(option 2), the user can choose the type according to the purpose of the evaluation. With this computer program. accurate and consistant evaluation of the quality of nursing care could be expected. Also. by the rapid feedback to nursing care practice. quality of nursing practice could be improved rapidly. and the systems of the evaluation criteria developed in this study could be used for the development of other moduls for various kinds of patient groups. Because this computer program was developed only for the purpose of research, it is necessary to be refined commercially to be used in real nursing situation.

Objective: To compare the positions of the mandibular premolars in Angle Class I subjects according to vertical facial type. The results will provide a theoretical basis for predicting effective tooth movement in orthodontic treatment. Methods: Cephalometric parameters were determined using cone-beam computed tomography in 120 Angle Class I subjects. Subjects were categorized as short, normal, and long face types according to the Frankfort mandibular angle. Parameters indicating the position of the mandibular right premolars and the mandible were also measured. Results: The angle between the mandibular first premolar axis and buccal cortex, the distance between the root apex and buccal cortex, angle of vestibularization, arc of vestibularization, and root apex maximum movable distance were significantly greater in the short face type than in the long and norm face types. The angle between the mandibular second premolar axis and buccal cortex, the distance from root apex to buccal cortex, and the arc of vestibularization were significantly greater in the short face type than in the normal face type. Conclusions: There are significant differences in the mandibular premolar positions in Class I subjects according to vertical facial type.

The KAMYOUNG is the supreme local government office in CHOSEON dynasty. This study aims to propose the new methodology on research of local government office's prototype in CHOSEON dynasty. Especially this study is the zoning plan of the KAMYOUNG in the late CHOSEON dynasty, It is meant to present the first trial that pursue to total frame of local government in CHOSEON dynasty through the new methodology. The 18th century is the transitional era when the system of norm was deconstructed. The institution and organization of the supreme lacal government office(KAMYOUNG) was united nationwidely and at the same time its deconstruction was carried out in the 18th century. The domain of the governer has fixed in the 18th century, though the scale of 街e KAMYOUNG was enlarged. These domain expressed a strong symbolization according to hierarchy in exterior appearance of the traditional architecture. With the entire execution of a local government coming soon, the concerns about the localization have been increased rapidly. Under this time situation, as the discussion centered on the creation or change of the local self-governing community, so the concerns regarding the traditional aspects of a local government office have been increasing. Hower, without the recognition of this history, as the research of these existing historical materials has been progressed, so the misunderstanding is still left. Especially, because the government office of CHOSEON is a Confucian nation thinking much of a hierarchy based on Yae - Jae, the hierarchy of this architecture has a deep correlation with the organization of an office. The method of this study is like following: Firstly, prescribed characteristic of KAMYOUNG tough syudys of hierarchy in a local government system, human and material composition. secondly, as the changing progress of KAMYOUNG is compared and analyzed with organization of an office in the center. So characteristics of KAMYOUNG are abstracted. And finally, from this, the interpretation methodology of KAMYOUNG is revealed, with a deep correlation between specific characters of organization and architectural structurals. And also, with these methodologies, the interpretation method of the local government office and normative frame in CHOSEON dynasty are suggested.

The purpose of this study is to identify the determinants of planned behavior of adolescent, toward information security and cyber crime prevention. A survey methodology was used to investigate a proposed model of influence, and regression analysis was used to analyze the results. The hypothesized model was largely supported by this analysis, and the overall results indicate that the intention to actively participate in information security and cyber crime prevention is mostly influenced by the fear for cyber crime and the perceived usefulness of information security and cyber crime prevention activity. In addition, it was found that the perceived easy of use for information-security related ICT skill, fear for cyber crime, and social norm for information security influence the level of usefulness, but that the prior experience with information leaking was statistically insignificant factor to the level of usefulness and fear for crime. Useful suggestions for promoting information security and cyber crime prevention are also provided.

The development of strain localization within shear zones is frequently observed during soil deformation. In fact, the phenomenon appears to be more often the norm rather than the exception. Conceptually, any soil condition that renders negative work increment is prone to localization. In this study, a broad range of soil and loading conditions are investigated to test this criterion, including: dilative soil subjected to drained shear (standard case), contractive soil sheared under undrained conditions, cavitation in dilative soil in undrained shear, inhomogeneous soils, particle alignment in contractive soils made of platy particles, soils that experience particle crushing, and the shear of low-moisture and/or lightly cemented loose soils. Unique specimens and test procedures are designed to separately test each of these soil conditions in the laboratory According to experimental test results, soil specimens with post-peak strain softening behavior are prone to progressive failure, localization of deformations, and shear banding. The state of stress, the soil density, inherent mechanical and geometrical properties of soil particles, low water content, and heterogeneity can contribute to triggering strain localization. Considering all possible cases of localization, the best method to obtain the critical state line in the laboratory is to use contractive homogeneous specimens subjected to drained shear.

The purpose of study is to understand human-technology integration mechanism by using the study model that takes the core concept and motivation assumptions of technology acceptance model(TAM) into account. This study identifies three motivation mechanisms in adopting or using computer mediated communication(CMC) tool for work. The mechanism comprises with extrinsic, extrinsic motivation, and subjective norm pressure. One hospital with 430 beds and 367 human power was identified and we administered the questionnaire during their work hours. There is 32.4% response rate. The fitting index of the study model surpass the acceptable level, GFI = .980 for none-users, GFI =.986 for users, NNFI = .973 for none-users, and NNFI = .989 for users. In the case of none-users, perceived ease of use determines perceived usefulness that explains behavioral intention to use. As a result, adotpers' usage motivation is based on extrinsic motivation that does not consider their affective factor, attitude, in use of CMC. Users considers their attitudes as the mediating factor of all behavioral beliefs for using CMC continually. Thus, users are likely to depend their adoption behaviors on their affective factor. Moreover, users' behavioral intention is subject to pressures of use from other persons who are important to them, such as supervisor, director, or boss. Achieving human-technology integration in a hospital may cause cost saving and work efficiency. However, the success of information system should base on a profound understanding of employees' adoption behaviors in rejecting, adopting, using, continually using of IT, and organization culture in using IT.

Purpose: The purpose of this study was to evaluate the theory of planned behavior (TPB) in the structural relationship of nursing students' performance related to nosocomial infection control (NIC). Method: Data was collected by using a questionnaire completed by 238 nursing students of three nursing colleges in Suwon, Sokcho. Results: The mean score of performance related to NIC was 3.86. The highest mean score of performance related to NIC was 4.18 (${\pm}0.91$) for 'hand washing' and the lowest mean score was 3.56 (${\pm}1.08$) for 'respiratory system'. In prediction of the intention of nursing students' on NIC, the attitude, the subjective norm, and the perceived behavior control(PBC) of TPB resulted in statistically significant influencing factors (p<0.050). These three variables explained 47.6% of the total variance of the intention of nursing students' on NIC. In predicting the performance related to NIC, the PBC resulted in the direct and main influencing factor of nursing students' performance related to NIC (p<0.010). Intention was not a significant determinant. These two variables explained 13.2% of total variance of the performance related to NIC. Conclusion: This study shows the TPB model's applicability in explaining performance related to NIC of nursing students and highlights the importance of PBC for strategies to enhance performance related to NIC in nursing students.

This paper proposes a multi-level vector error diffusion method using 64 primary colors to improve color impulse artifact in bright region. Vector error diffusion method causes color impulse artifact in bright region because we only use the Euclidean distance measure in quantization process. In order to reduce this artifact, the proposed method divides input color into chromatic color and achromatic color according to chroma value. In the case of chromatic color, input color is classified into bright region, middle bright region, and dark region according to lightness value. N candidate primary color is organized using lightness difference between input vector and 60 chromatic primary color vector in the case of bright region. Then, primary color with minimum vector norm between input vector and N candidate primary color in addition to 4 achromatic primary colors is selected as output color. As a result of experiments, the proposed method showed visually pleasing halftone output.
