Corporate managers look at IT outsourcing as long-term strategic choices not as short-term tactical ones, and maximizing the effect that IT outsourcing brings about is the main concern to them. Emerging different types of IT outsourcing and their effects on the corporate business decisions necessitate the research on this subject. According to previous researches, the Intent for IT outsourcing is categorized as IS Improvement, Business Impact, and Commercial Exploitation. The decison factors for these IT outsourcing include corporate strategy types, IT role, and interaction between these two. Firm size and IT maturity are selected as moderating factors to add the credibility to the research of the effect of IT outsourcing decision making. Analyzing IT outsourcing data collected from 61 large-size and mid-size domestic firms revealed that corporate strategy rather than IT role is more significant factor affecting the intent for IT outsourcing decision. That means the decision of outsourcing intent is affected by corporate strategy types. Defenders(as in corporate strategy types) tend to use IT outsourcing more as a means to improve information systems, compared to analyzers and reactors. Prospectors tend to use IT outsourcing more as a commercial exploitation, compared to analyzers and reactors. These outcomes prove that corporate strategy characteristics reflect outsourcing intent. There were previous researches that showed outsourcing decision depends on IT role however the hypothesis was rejected that IT role determines outsourcing intent. It was also rejected that the interaction between corporate strategy types and IT role determines outsourcing intent. Corporate decision makers should first analyze corporate strategy, and reflect it on the outsourcing intent when they make IT outsourcing decisions. Only the precise defining of IT outsourcing intent will lower the risk and increase the possibility of success.

Objectives: The aim of the research was to evaluate the recognition levels on PHR (Personal Health Record) which was regarded as a valuable tool in health areas. Old and young age groups (mostly university students) were two groups that were under investigation. The young age group was deliberately asked to pretend they were members in the old age group (adult group here after) in order to investigate the recognition level differences in such conditions. Methods: We performed common and grouping analyses based on two hypotheses. Firstly the survey results should be different in both age groups. Secondly people who had high risk factors of a disease (obesity in our study) should show higher recognition level on PHR based on an assumption that they were aware of serious outcome of the disease more than the others. Results & Conclusion: The first hypothesis was rejected as both groups show similar patterns in responding the survey. The second hypothesis was also rejected because both groups showed responses in similar patterns. Based on the outcome of our study and analyses, we concluded that there would be no differences in recognition levels on PHR between young and adult groups. Also, possession of disease risk factors, at least for obesity, would not affect the recognition level of PHR. Further elaborate researches with larger groups on the topic may be necessary in order to validate the method and to expand for various applications.

According to the Fregean theory of meaning based on the distinction between sense and reference,the cognitive significance of coreferential names may be distinct or The so-called direct reference theorists. however,claim that unamhbiguous,coreferential names.which have the same denotation from context to context, must have the same cognitive significance.Thereby,Fregean senses,counted as intermediate entities that determine the denotation of a term,are altogether rejected.Once Fregean senses are rejected.however,it is hard to explain why the substitytivity of coreferential names fails in the contexts of propositional attitudes.Thus,the puzzles of propositional attitudes have been the stumbling block for direct reference theorists. Recently, Zalta claimed that by small amendation it is possible to reconcile the conflicting views of Fregeans and the direct reference theorists without losing their important insights.Indeed, he claimed that his suggestion admirably solves the propositional puzzles.In this article,we shall critically examine his eclectic solution only to highlight some of the more basic issues.

In this paper, we propose a technique to improve Out-Of-Vocabulary(OOV) rejection algorithms in variable vocabulary recognition system which is much used in ASR(Automatic Speech Recognition). The rejection system can be classified into two categories by their implementation method, keyword spotting method and utterance verification method. The utterance verification method uses the likelihood ratio of each phoneme Viterbi score relative to anti-phoneme score for deciding OOV. In this paper, we add speaker verification system before utterance verification and calculate an speaker verification probability. The obtained speaker verification probability is applied for determining the proposed variable-confidence threshold. Using the proposed method, we achieve the significant performance improvement; CA(Correctly Accepted for keyword) 94.23%, CR(Correctly Rejected for out-of-vocabulary) 95.11% in office environment, and CA 91.14%, CR 92.74% in noisy environment.

Lightning induced faults accounts for more than 66% at the transmission lines of KEPCO. The lightning causes damages to power system equipments including transmission line, the blackout of electricity and the electro-magnetic interference. Because of this reason, we need the real time lightning information for the optimal operation of power system. And, it is required to obtain and accumulate the lightning current parameters for the insulation design. In 2005, KEPRI constructed a lightning detection network, the KLDNet (i.e. Kepco Lightning Detection & Information System) and launched a lightning information service for KEPCO customers. It is intended to provide data service on the operation of transmission lines and collect lightning-related data, which is the most important factor regulating power system design and operation. The new system will replace LPATS, the old detection system, which has been operating since 1995 and is rapidly failing in terms of both detection performance and location accuracy. The purpose of this paper is to explain the work performed and the results of that work in performing a site survey of several locations. The purpose of the site survey is to find locations acceptable for the installation of a lightning location receiver in support of a Lightning detection system(LDS). A restriction was placed on the surveyed locations, as they must belong to the Korea Electric Power Company. This requirement was made to facilitate the communication needs of the LDS network. Total of 15 sites were evaluated as possible LDS sensor sites. Some of the sites were rejected for physical reasons and therefore no electrical testing was performed. Of the 15 sites, total of 10 sites were considered acceptable and 5 sites were rejected for various reason. In this paper, we would like to explain the site survey and detection efficiency for LDS.

The purpose of this study was to determine the effect of dance sports on physiological variables, depression and quality of life in the elderly. The study was performed on a non-equivalent control group pretest-posttest design for 47 elderly, who were conveniently assigned to experimental group and control group. The experimental group were selected from D-welfare facility and the control group were selected from G-elderly church club in G-city. The data were collected from April 2, 2001 to June 30, 2001, and analyzed by frequency, $x^2$-test, t-test and paired t-test using SAS/PC program. The results of this study were summarized as follows; 1. The first hypothesis, "the experimental group would have improved physiological variables than the control group.". 1-1. The hypothesis, "the experimental group would have lower blood pressure than the control group" was rejected. 1-2. The hypothesis, "the experimental group would have lower heart rate than the control group" was supported(t=-2.031, p=0.048). 1-3. The hypothesis, "the experimental group would have higher peripheral vessel $O_2$ Saturation than the control group" was rejected. 2. The second hypothesis, "the experimental group would have lower depression score than the control group" was supported(t=2.832, p=0.006). 3. The third hypothesis, "the experimental group would have higher quality of life score than the control group" was supported(t=2.604, p=0.012). After 12 weeks of dance sports program, it was shown that the program was effective to improve the physiological varibles, reduce depression and improve quality of life.

There has been a gradual increase in distribution of counterfeit products and resulting damage cases from companies and consumers. It examines which antecedent variables have significant effects on consumer perceived satisfaction or regret. To test the related hypotheses, such antecedent variables as the utilitarian value, the hedonic value, legal regulations, and ethical mentality of consumers were examined and also did whether these factors have differences between Korean and Chinese consumers. Findings from the empirical analysis are as follows. First, Korean and Chinese consumers' perceived utilitarian value and hedonic value in counterfeit products in contrast to original products are found to have a positive influence on consumer perceived satisfaction with counterfeits while they have a negative influence on consumer perceived regret with counterfeits. Second, in the case of Korean consumers, the hypothesis that legal regulations on counterfeit products will influence the degree of regret with counterfeit products has been rejected. And it is found that the more ethical Korean consumers are, the more regretful for their post purchase they feel. Third, in the case of Chinese consumers, the hypothesis that legal regulations and ethical on counterfeit products will influence the degree of regret with counterfeit products has been rejected. Therefore, it can be said that the results in this paper provide significant implications for government policy, legal regulation and enforcement, and some need for a change in consumer consciousness and attitude as well as for marketing strategies of Korean and Chinese famous brand manufacturing companies.

Health at infancy and early childhood is considered an important factor for healthy life thereafter. Concept of nursing is inclusive not only of physical care but also psycho-social aspect in order to help achieve maximum state of wellness. Statistical studies reveal concept and structure of family and home tends to change towards nuclear type, ratio of female occupancy tends to increase. These tendencies will influence the method of infants and children. Purpose of this study is to investigate the characteristics of mothers and their children with and without occupation, method of nurturing and analyse data according to various variables, in arnder to give data for care for infants and children. During the period of June 12 though July 22, 1973, 98 mothers and their 224 children; 53 mothers with occupation with 110 children and 45 mothers without occupation with 114 children were Interviewed indirectly through check list. Results of the studies are as follows: 1. Hypothesis 1 ; Tendencies of finger sucking will be greater in children of occupant mothers due to lack of maternal love. Through chi-square examination significant difference is revealed by P>0.05 level, therefore Hypothesis 1 is rejected. (X²=0.24) 3. Hypothesis 2; of occupant mothers tend to have had wanted number of children through family planning. Ratio of wanted versus unwanted children were tested and significant difference is revealed by P<0.05 1eve1. Hypothesis 2 is supported. (X²=8.398). 3. Hypothesis 3: Non-occupant mothers tend to cuddle more while feeding infants. Significant difference Is revealed through Chi-square test by P〈0.05 level. Hypothesis 3 is rejected. (X²=4.34) Conclusion and recommendations: Occupant mothers' higher degree of interest and consideration compared to that of non-occupant mothers in regard to nurturing of their children have been ascertained by this study. These results fight have come up due to the differences of socioeconomic and cultural status of respondents. Further studies on each variable between mothers with and without occupation with similar socio-economic and cultural background are recommended.

Evaluation for students’performance is a very important and difficult responsibility of head nurses. This study was undertaken to investigate and identify head nurses’attitudes toward evaluation for clinical performance of nursing students. Data were gathered through questionnaire from eighty eight head nurses at three hospitals in Kwang Ju City and four hospitals in Seoul, during the period of April 9th-26th, 1978. The questionnaire developed by the researcher included 19 statements which concerned the attitudes of head nurses: their perception about objectives of evaluation for the students clinical performance, their attitudes toward responsibility as evaluator, their attitudes toward method of evaluation, their understanding and interest in nursing students. Mean attitude score more than 60% were classified as positive or favorable, and less than 60% to be negative or unfavorable. The result obtained could be summerized as follows: 1. The mean score of head nurses’attitudes was positive (67.9%). Hypothesis I was rejected, 2. Head nurses’perception about objectives on performance evaluation was very favorable (85.5%). 3. Head nurses’attitudes toward evaluating method were negative (50.9%), post-evaluation interview were perceived to be a part of evaluating process (73.9%), although only few (22.7%) implemented. 4. The head nurses’attitudes in the responsibility as a evaluator were unfavorable (58.2%). 5. Relatively favorable response was revealed in understanding and interest about nursing students (79.6%). 6. Educational level, duration of clinical experience, marital status, and geographical region of head nurses were no significant influence on the attitudes toward evaluation for clinical performance (P > 0.05), while only age revealed significant difference (P < 0.05) Hypothesis 2, 3, 5 and 6 were accepted, hypothesis 4 was rejected.

The purposes of this study were to(a) develop theoretical modifications of the extended gate control theory of pain using Fishbein's model and（b) test the efficacy of these modifications. Attitude, social subjective norm, personal subjective norm, habit and state anxiety were operationalized to represent internal stimuli for the cognitive-evaluative and motivational-affective dimensions of the theory. Pain expression was operationalized as sensory and affective responses to pain, and pain endurance. Sixty-two female nurses from 20 to 50 years of age participated. A semantic differential scale measured attitude and motivations to comply; a Likerty-type scale measured personal and social norms and habit. Spielberger's STAI measured state anxiety, Pain was produced using a modified submaximum effort tourniquet technique. Pair expression was measured using ratio scales of sensory intensity and unpleasantness developed by Gracely and his associates. Pain endurance was measured by subtracting time of pain threshold from pain tolerance. The first hypothesis examining whether pain endurance would be more significantly related to the affective response than to the sensory response was net rejected. Four remaining hypotheses, testing the ability of the five variables to predict the sensory and affective responses were not rejected. However, the habit of pain expression and the attitude toward pain expression contributed to the prediction of both sensory and affective responses to pain. The interaction between the cognitive-evaluative and the sensory-discriminative dimensions and the interaction between the cognitive-evaluative and motivational-affective dimensions were partially supported by the data from these two variables. The interaction between the motivational-affective and the sensory-discriminative dimensions was also supported by the relationship of sensory to affective responses. The variables which did not significantly predict pain expression appeared to have potential for prediction. Revision and testing of the tools for better reliability, validity, and clinical usuability are needed. The study contributed to theory building. The identification of variables which pre-dict pain behavior must occur before effective nursing interventions can be developed.
