Recently there have been many efforts to develop hypermedia systems. Hypermedia applications can be categorized into process-oriented or contents-oriented. However, it is not a trivial task to build contents-oriented hypermedia in a systematic fashion. The contents-oriented hypermedia systems are developed primarily for the applications of marketing or information services. This paper proposes a methodology for a contents-oriented hypermedia system. Hypermedia contents are typically structured in the form of hierarchies. An index node can be used in order to give an effective access to this hierarchical structure. The proposed methodology employs three types of nodes(contents, index and function) and various navigation mechanisms, and helps design contents-oriented hypermedia systematically. Furthermore, various design techniques are proposed for maintaining contents-oriented hypermedia systems that have an evolutionary feature. Two real-life cases are illustrated to demonstrate the applicability of the methodology.

Objective : The purpose of this study was to investigate the effects of task-oriented training with functional electrical stimulation on hand function in incomplete cervical cord injury. Method : The subjects of the study were 3 adults diagnosed as incomplete cervical cord injury. The design of this study was ABA single-subject research design to compare dominant hand function of before and after intervention and detect individual effects. The experiment consisted of 30sessions, in which baseline process A1 and A2 were implemented 5 sessions each for 10sessions. Intervention B was implemented 20 sessions. The dependent variable was converted to the change of hand function every session, and Canadian Occupational Performance Measure (COPM), Jebsen-Taylor Hand Function Test(JTHFT), Wolf Motor Function Test(WMFT) were selected for outcome measurements. Result analysis was suggested through visual analysis using a graph and comparison of pre, post and follow-up intervention measurements. Results : As a result, the quality and quantity of dominant hand function increased during intervention B compared to the baseline A1 for all subjects. Baseline A2 was also maintained without training. Additionally, JTHFT, WMFT and COPM scores demonstrated improvement and maintain. The follow up JTHFT and WMFT showed increased required time on all subjects and decrease or maintain task performance and satisfaction in COPM. Conclusion : The task-oriented training with function electrical stimulation in this study has been positive effects on hand function and task performance and satisfaction.

The object-oriented design methods and their CASE tools are widely used in practice by many real-time software developers. However, object-oriented CASE tools require an additional step of identifying tasks from a given design model. Unfortunately, it is difficult to automate this step for a couple of reasons: (1) there are inherent discrepancies between objects and tasks; and (2) it is hard to derive tasks while maximizing real-time schedulability since this problem makes a non-trivial optimization problem. As a result, in practical object-oriented CASE tools, task identification is usually performed in an ad-hoc manner using hints provided by human designers. In this paper, we present a systematic, schedulability-aware approach that can help mapping real-time object-oriented models to multi-threaded implementations. In our approach, a task contains a group of mutually exclusive transactions that may possess different periods and deadline. For this new task model, we provide a new schedulability analysis algorithm. We also show how the run-time system is implemented and how executable code is generated in our frame work. We have performed a case study. It shows the difficulty of task derivation problem and the utility of the automated synthesis of implementations as well as the Inappropriateness of the single-threaded implementations.

In this paper, the task-oriented optimal configuration in the sense of Velocity and Force manipulability measure of manipulator mounted on ROV is considered. Manipulability is a quantitative measure of manipulator's capability obtained under the limits of joint velocities or torques. The base arrangements and optimal joint configuration of manipulator, that maximize the manipulability measure under the constraints of given task, are investigated. With the two types of base arrangements of manipulator, workspace analysis is carried out to investigate merits and demerits of each arrangement on the view of manipulability measure. To find optimal joint configuration for a given task with each arrangement, the SQP(Sequential Quadratic Programming) optimization are performed. Weighted linear combination of velocity and force manipulability measure is object function for SQP optimization. The kinematic parameters of Dual Orion manipulator which will be mounted on KORDI ROV are used for simulation.

Service-Oriented Architecture(SOA) define the interaction method between two computing entities that one entity performs a unit task instead of another entity. This, unit task, is called "Service" and interaction of these services should have independency and loosely coupled task. The effect of SOA's main functions such as loosely coupled task and independent interoperability with influence the possibility of flexible message communication between different way and different users. In this article, we analyzed the performance about system stabilization between general web service and SOA based application that implemented through WCF based messaging framework using .NET Framework and integrated data presentation method. As the result of test, we confirmed that SOA environment using WCF have more advantages.

Purpose: The purpose of this study was to identify factors influencing workplace bullying among Korean hospital nurses. Methods: Subjects in this study included 178 hospital nurses who attended two nationwide nursing educational conferences in 2013. The data was collected using self-report questionnaires which were used to identify the subjects' characteristics, self-esteem, perception of nursing organizational culture, and workplace bullying experience. Results: The results showed that 19.1% of study subjects reported being victims of workplace bullying and mostly experienced person-related and work-related bullying. Multiple regression analysis was done to identify factors affecting workplace bullying. The perception of relation-oriented culture, task-oriented culture and self-esteem turned out to be variables that explained nurses' workplace bullying, and these factors accounted for 32.0% of the variance. Conclusion: The findings suggest that nurses experience more workplace bullying in task-oriented cultures. However, they experience less bullying and report higher self-esteem and awareness in relation-oriented cultures. Interventions focused on the characteristics of the organization need to be developed to prevent workplace bullying in hospital nurses.

The purpose of this study is to verify the mediating effect of interaction among learners in a Web Based Collaboration Learning (WBCL) environment. 254 Korean college students served as test subjects and during the 4 weeks of research period, they studied the Test of English for International Communication (TOEIC) in a web-based collaborative learning system. The interaction between learners was looked into by categorizing the concept into task oriented information sharing activities and relationship oriented communication activities and analyzing the causal relationship between the two activities. Learning performances were measured in individual level. The results are as follows. First, task oriented information sharing activities effect positively on relationship oriented information sharing activities. Second, the managerial characteristics of WBCL had a positive effect on interaction between learners but the systematic characteristics had partial influence on interaction between learners. Third, the interaction between learners completely interconnects the managerial characteristics of WBCL and learning performance but partially interconnects the systematic characteristic of WBCL and learning performance. In conclusion, this study implies that managerial and systematic characteristics of WBCL should be considered on the preferential basis for the WBCL to become successful and interactive activities such as information sharing and communication should be encouraged to be active from a small-size WBCL perspective.

Nowadays, customer-oriented manufacturing enterprises such as airplane, ship, ship engine, etc are knowledge-intensive and higher added value industries. In these companies, to quickly respond customer's order, a quotation management is a very important task. But, this task is very complex, time-consuming, resource- consuming, and difficult process because it is related with many departments within a company. In this paper, for the effective and efficient quotation management, the concept of product specification framework is introduced because a quotation BOM (bills of material) can be created from product specification. Also, this paper presents the product specification framework based quotation management process and implements the quotation management system for the ship engine division of 'H' company, one of customer-oriented manufacturing enterprises. As a result, the proposed quotation management concept reduced a lead time of drawing out quotations from $3{\sim}10$ days to 1 hour. And, the constructed quotation management system achieved a rapidity, accuracy, quality, and workload reduction of the quotation management process.

The purpose of this study was to identify job satisfaction and organizational commitment depends on their organizational cultures. A survey, including the Organizational Culture Scale, Job Satisfaction Scale and Organizational Commitment Scale, was administered to 276 nurses working at 4 small to medium sized hospitals in B city. The dominant organizational culture of nursing organization was relation-oriented culture. The mean score of job satisfaction and organizational commitment was 2.68 and 4.25 respectively. Job satisfaction and organizational commitment were positively correlated with innovation-oriented, task-oriented and relation-oriented culture. Organizational commitment was negatively correlated with rank-oriented culture. Innovation-oriented, clinical career, relation-oriented and rank-oriented culture were variables influencing on job satisfaction and innovation-oriented and rank-oriented culture were major variables influencing organizational commitment. In conclusion, innovation-oriented and rank-oriented culture had a significant influence on nurses' job satisfaction and organizational commitment. Therefore, we have to develop strategies to enhancing the innovation-oriented culture and to reducing the rank-oriented culture.

The purpose of this study was to investigate the effects of the task-oriented training according to the application time with the change of motor and cognition function. Focal ischemic brain injury was produced in Sprague-Dawley rats (20 rats, $250{\pm}50$ g) through middle cerebral artery occlusion (MCAo). Before MCAo induction, all rats were trained in treadmill training and Morris water maze training for 1 week. Then they were randomly divided into groups: Group I : MCAo induction ($n_1$=5), Grop II: the application for simple treadmill task training after. MCAo induction ($n_2$=5). Group III: the application for Morris water maze cognitive task training after MCAo induction ($n_3$=5). Group IV: the application for progressive treadmill task training and Morris water maze cognitive task training after MCAo induction ($n_4$=5). Modified limb placing tests (MLPTs) and motor tests (MTs) were performed to test motor function and then Morris water maze acquisition test (MWMAT) and Morris water maze retention test (MWMRT) were performed to test cognitive function. For MTs, there were significant interactions among the groups with the time (p<.001). Group IV showed the steeper increasing pattern than those in other Groups on the 7th and 14th day. For MLPTs, there were significant interactions among the groups with the time (p<.001). The scores in Group III. IV had showed the more decreasing pattern than those in Group I, II since the 7th day and 14th day. For MWMAT, there were significant interactions among the groups with the time (p<.001). Group II found the Quadrant circular platform showed the steeper decreasing pattern than that in Group I on the 9th, 10th, 11th and 12th day. Group III. IV found the quadrant circular platform showed the slower decreasing pattern than that in Group I, II, For MWMRT, there were significant differences among the four groups (p<.001). The time to dwell on quadrant circular platform in Group IV on the 13th day was the longest compared with other groups. These results suggested that the combined task training was very effective to improve the motor and cognition function for the rats affected on their focal ischemic brain injury.
