Purpose: This research was, by investigating the relations between the cultural types of a nursing organization in military hospital and performance, to ascertain the cultural types to be able to improve performance. Method: The date were gathered from 255 nurse officers who were in 19 military hospitals by using the self-report type of questionnaire. The period of data collection was from April 20, 2003 to July 15, 2003. For this research, the following tools were used: the tools for measuring the organizational characteristics, organizational culture, and job satisfaction, the tool for measuring organizational commitment. For data analysis the SPSS Win 12.0 program was used. Result: 1) Most of the cultural types of a nursing organization in military hospital is Relation-oriented. 2) In the relation between general the characteristics of subject and the organizational cultural type, there was a difference in the innovation-oriented, relation-oriented, hierarchy-oriented, and task-oriented culture according to nurse officers careers, hospital types, year in hospital, marital status, and unit(p<0.05). 3) In the relation between general characteristics of subject and organizational performance, there was a difference in the job satisfaction, affective commitment, transactional commitment, and normative commitment according to nurse officers careers, education, madrigal status and unit(p<0.05). 4) In the relationship between the of a military hospital were correlated with the type of each culture(p=0.00), 5) In the relation between the organizational culture type of military hospital and its performance, there was a positive correlation among job satisfaction and innovation-oriented culture, relation-oriented culture, task-oriented culture(p<0.05). And hierarchy-oriented culture showed that they had a weak negative correlation with job satisfaction(p<0.05). There was a positive correlation among affective commitment and innovation-oriented culture, relation-oriented culture, task-oriented culture(p<0.05). And hierarchy-oriented culture showed that they had a weak negative correlation with affective commitment(p<0.05). There was no culture type significantly related to continuance commitment and there was a weak positive correlation among normative commitment and innovation-oriented culture, relation-oriented culture, task-oriented culture. The types to have an influence upon nurse officers' job satisfaction were relation-oriented culture and innovation-oriented culture(p=0.00). And relation-oriented culture and innovation-oriented culture were major variances for affective commitment and only relation-oriented culture was influential variance for normative commitment(p=0.00). Conclusion: The organizational culture type was found which had an influence upon nurse officers' job satisfaction and organizational commitment.

In this study, we developed a comprehensive model to measure the National Information Security Level based on PRM framework. The proposed model reflected a rapidly changing technology environments such as social network service, mobile devices, and etc. This new model consists of three layers:Infrastructure Layer, the Action Layer and the Performance Layer, and there are 16 sub-indexes under the 3 layers. To develop new model and sub-indexes for measuring the National Information Security Level, much amounts of documents related to security indexes or deliberation criteria and security guidelines from international organization were reviewed and then most probable index pool were composed. The Index pool were verified by expert group consisting of professors and specialists. Through five times of screening and having an evaluation review, 16 sub-indexes were deduced and then Delphi and AHP have been conducted to obtain validity and objectiveness of the indexes. Thus the new proposed national information security index will show more exact national information security level and we expect that the indexes give much implications for establishing information protection policy.

Purpose: This study was conducted to extract international classification of functioning, disability, and health (ICF) core sets for measuring functional status in acute stroke patients, and to evaluate clinical applicability of the core sets. Methods: A set of 22 ICF items on functional status in acute stroke patients were extracted from the Korean general ICF core sets and ICF core sets for stroke patients. The extracted ICF functional items were assessed at the time of admission and discharge among 100 stroke patients who were admitted in a university hospital. Results: Comparing to functional status at admission of acute stroke patients, the overall functional status at discharge was improved. However, functions on defecation, skin protection, and relationship with immediate family at the time of discharge were not significantly changed. Conclusion: The set of ICF functional items identified in this study may be reliable and valid to assess acute stoke patients' body functions, activities and participation and environmental factors in the holistic and comprehensive nursing context. Nursing interventions on bowel elimination and skin protection for acute stroke patients need to be developed.

The purpose of this study was to develop math creative problem solving test in order to identify the mathematically gifted on the basis of their math creative problem solving ability and evaluate the goodness of the test in terms of its reliability and validity of measuring creativity in math problem solving on the basis of fluency in producing valid solutions. Ten open math problems were developed requiring math thinking abilities such as intuitive insight, organization of information, inductive and deductive reasoning, generalization and application, and reflective thinking. The 10 open math test items were administered to 2,029 Grade 5 students who were recommended by their teachers as candidates for gifted education programs. Fluency, the number of valid solutions, in each problem was scored by math teachers. Their responses were analyzed by BIGSTEPTS based on Rasch's 1-parameter item-response model. The item analyses revealed that the problems were good in reliability, validity, difficulty, and discrimination power even when creativity was scored with the single criteria of fluency. This also confirmed that the open problems which are less-defined, less-structured and non-entrenched were good in measuring math creativity of the candidates for math gifted education programs. In addition, it discriminated applicants for two different gifted educational institutions and between male and female students as well.

For the last decade, some leading groups of corporations in Korea have integrated and managed their Information Systems(IS) functions. Each group established a separate System Management(SM) company to manage the IS and tried to get a synergy effect from the integration. These attempts, however, were not initiated by any one company. Rather they were group efforts. Moreover, the previous measuring tools evaluated IS with the scope of technical performance or quantitative user satisfaction using an absolute scale. Obscure criteria were used in an attempt to present improvements in IS function which were qualitatively weak. This study evaluates whether integration has been efficient and successful. For this purpose, we evaluate the performance efficiency of IS functions with Data Envelopment Analysis(DEA) methodology. In comparison with prior methods, DEA presents the rate of relative efficiency, the efficiency frontier for improving inefficiency, the degree of improvement(slack), and the guideline to construct any benchmark(reference set). For our DEA evaluation, this study selected a leading group of 23 companies in Korea. Our experimental results are as follows. First, efficiency was rated low on average. It also demonstrates that the motivation of performance efficiency of IS functions is deficient. Second, the result of the test to find the existence of economy of scale and scope shows that the growth of an organization and industrial characteristics do not affect IS performance efficiency from the perspective of user satisfaction. Finally, the comparison with other evaluation approaches informs us that DEA can be a complementary evaluation method which supports other measuring tools.

The paper is to solve the problem of existing audio signal transfer system which has a difficulties of system organization and the increase of additional install cost and unfriendly interior. To solve the existing system, we drew the new audio signal transfer system based on PLC and evaluated it. A transmitter and a receiver were designed using the PLC chip INT5500CS. An audio signal transfer system was configured with a CD player to which audio signals are sent from the transmitter and a speaker connected to the receiver. For performance evaluation of this system, a USBPre external sound card and Smaart Live 5 which is a PC-based sound measuring program were added. As a result of our experiment, the measured signal level is $2{\sim}3$ dB lower than reference signal, latency is 16.69 ms, and the specific character of coherency is bad in high frequency band. Otherwise, this system transmits and receives signals over 90 % in good condition as a result of measuring pink noise, frequency (1 kHz), and phase, magnitude. In view of the result so far achieved, the system designed this study has excellent performance, it resolves defect of existing audio signal transfer system.
