The objective of our study is to build a theoretical framework for the examination of impacts of cross-functional integration upon new product development performance(NPDP). For this purpose, we have concentrated our efforts on systematically delving into how cross-functional integration factors affect upon the interdepartmental cooperation and upon the NPDP while dividing those critical integration factors into the structural and the infra-structural ones. We have selected interdepartmental job-rotation, consigning of papers, and cross-functional teem meeting as structural cross-functional integration factors. On the other hand, we have chosen Quality Functional Deployment(QFD), Concurrent Engineering(CE), and Evaluation and Reward Systems as those infra-structural cross-functional integration factors. After identifying those integration factors, we have carefully searched the relationship between those integration factors and those cooperation variables (interdepartmental common goal, interdepartmental interactions, and common sharing of ideas and informations) to look into how they affect upon the NPDP. Among cross-functional integration and NPDP related studies, our study is the first to show systematically how strongly infra-structural integration factors affect upon the achievement of interdepartmental cooperation and the improvement of NPDP. Considering the limitation of our resources and time available for this research, we have limited our study to building only a theoretical framework for future empirical studies to look into how cross-functional integration variables are related with NPDP.

The purpose of this study is to analyse the overall relationship between the advertisement expenses and the two major indicies of business performance, that is, the total amount of sales and the discipline have contrasted the expenses for commercial advertisement with the total amount of sales or with the business performance, respectively, utilizing data on a specific product observed through 3 to 5 years. This study attempts to enlarge the scope of observation and the content of analysis. In order to attain the purpose of this study, the rate of increase in the advertisement expenses is taken as the independent variable and the two major indicies of business performance, the total amount of sales and the resultant interest, as the dependent variables. Business companies or firms which have continually been listed on the board of Korea Stock Exchange for 14 years, from 1982 to 1995, were grouped into four major business categories; 1)Food and beverage industries, 2)Fiber, clothings, and leather industries, 3) Medicine, chemistry, oil, coal, and rubber industries, and 4) Assembled mechanics and metallurgy, machinery, and maintenance industries. Utilizing the KIS-DATA, compiled by Korea Credit Evaluation, Ltd., 30 to 40 samples of business companies or firms were randomly selected from each category. Finally 125 samples were selected and put into regression analyses and follow-up tests by appropriate statistical models, in order to verify if there were any noticeable correlations. The final result obtained through the afore-mentioned research method shows that the amount of advertisement expenses has strong correlations with the amount of sales and the resultant interest. Viewed by business category, in the case of fiber, clothings, and leather industries, the relationship turned out to be significant only with the rate of increase in the total amount of sales, while, in the case of food and beverage industries, the rate of increase in the total amount of sales showed a negatively significant correlations.

The purpose of this study is to develop an engineer competency model using Analytical Hierarchy Process (AHP) to improve the national technical qualification system. Korea has managed technical human resources at the government level through the operation of a national technical qualification system that certifies engineers with national certificates or technical grades by laws. However, there have been increasing concerns that the government system is separated from global standards and does not reflect an engineer's comprehensive capabilities. For these reasons, the new architecture of the system has been continuously discussed and becomes a major policy issue of the Korean government. For the development of the engineer competency model, domestic and global models were separately structured using 554 valid questionnaires with a consistency ratio (CR) of 0.1 or less. The relative importance of engineer competency factors in a domestic model was career (0.383), qualification (0.253), academic degree (0.195), and job training (0.169) whereas the order in the global model was career (0.308), global ability (0.237), job training (0.175), domestic qualification (0.147), and academic degree (0.134). The results of AHP analysis indicated that the evaluation factors and methods recognized by engineers were different from a current government model focusing on domestic qualifications. There was also perceptual difference in the importance of engineer evaluation factors between groups depending on the type of organizations and markets. This means that it is necessary to reflect the characteristics of organizations and markets when evaluating engineer competency. Based on AHP analysis and literature reviews, this paper discussed how to develop a new engineer competency index (ECI) and presented two effective index models verified by simulation test using 59,721 engineers' information. Lastly, the paper discussed major findings of our empirical research and proposed policy alternatives for the improvement of a national engineer qualification system. The paper contributes to the management of technical human resources since it provides quantitative competency models that are objectively developed by reflecting market recognition and can be effectively used by the policy makers or firms.

We examine the intertemporal relation between risk and return in the Korean stock market and foreign exchange market based on the two factor ICAPM framework. The standard GARCH model and the GJR(1993) model are employed to estimate conditional variances of the stock returns and foreign exchange rates. The covariance between the rates of stock returns and changes in the exchange rates are estimated by the constant conditional correlation model of Bollerslev(1990) and the dynamic conditional correlation model of Engle(2002). The multivariate GARCH in mean model and quasi-maximum likelihood estimation method, consequently, are applied to investigate riskreturn relation jointly. We find that the estimated coefficient of relative risk aversion is negative and statistically significant in the post-financial crisis sample period in the Korean stock market. We also show that the expected stock returns are negatively related to the dynamic covariance with foreign exchange rates. Both estimated parameters of conditional variance and covariance in the foreign exchange market, however, are not statistically significant. The GJR model is better than the standard GARCH model to estimate the conditional variances. In addition, the dynamic conditional correlation model has higher explanatory power than the constant correlation model. The empirical results of this study suggest following two points to investors and risk managers in hedging and diversifying strategies for their portfolios in the Korean stock market: first, the variability of foreign exchange rates should be considered, and second, time-varying correlation between stock returns and changes in foreign exchange rates supposed to be considered.

The purpose of this study was to examine variables affecting the occupational aspiration of elementary school students and the relationship of the variables in a bid to acquire empirical information on influential factors for the development of children's occupational aspiration. Out of the personal characteristics of school children, academic achievement, self-esteem and parental educational level that respectively belonged to the cognitive, affective and environmental domains were selected as the variables that might affect occupational aspiration. And the relationship of the variables to the level of occupational aspiration was selected as a research question of the study. The findings of the study were as follows: in relation to the level of occupational aspiration by gender, the girls were ahead of the boys. There were no statistically significant gaps in that aspect according to grade. And, the academic achievement of the elementary school students had a positive correlation to the level of their occupational aspiration, and there was no statistically significant relationship between self-esteem and the level of occupational aspiration. When academic achievement and self-esteem were selected as predictors, the two variables made a 8.5% prediction of the occupational aspiration of the fourth graders, and made a 12.3% prediction of the occupational aspiration of the sixth graders. There were no statistically significant differences in the level of occupational aspiration according to parental educational level. The fourth and sixth graders were found to have an occupational aspiration in consideration of not only the characteristics of occupations but their own academic achievement, namely their abilities.

The purpose of this correlational study was to offer strategies for nursing intervention to improve compliance with prenatal care. This study was designed to investigate degree of tardiness, correlation between hardiness and compliance with prenatal care. In research, the characteristic of hardiness has 1 teen demonstrated in resolving stressful situaltions and in adapting to overcome physical and psycho-logical tension. pregnancy is normal crisis process. Therefore, it is necessary to investigate degree of hardiness in normal pregnant woman and I think that concept of hardiness is able to become a new, important concept for prenatal care imtervention. The subjects were 388 normal pregnant woman over five months, who were selected from five university hospitals and two health centers in Taegu. Data were obtained using a convenience sample technique. Data collection was done from March 6 to June 18, 1992. The instruments used for this study were the Health Related Hardiness Scale developed by Pollock(1984) and compliance with a prenatal care scale developed by the author on the basis of results of a literature review. Data were analyzed using the SAS program for t - test, ANOVA, Scheffe test, Pearson correlation and stepwise multiple regression. The results are as follows : 1. The scores on the hardiness scale ranged from 35 to 210 with mean of 88.89. 2. The scores on the compliance with prenatal care scale ranged from 28 to 140 with a mean of 111.49. 3. There were significant differences between hardiness and obstetrical characteristic factors, duration of pregnancy, frequency of pregnancy, frequency of abortion(P .05). 4. There were significant differences between compliance with prenatal care and general and obstetircal characteristic factors, education and frequency of pregnancy(P .05). 5. Correlations between hardiness and compliance with prenatal care were all negative and significant(r=-.2276~ -.2930, P .000). Challenge of hardiness components was the low est (r= -.2814). 6. Significant differences between hardiness and compliance with prenatal care by group were as follows : Group 1 was the high est, whereas Group 8 was the lowest(F=5.47, P .0000). 7. Factors influencing compliance with prenatal care were : 1) Challenge was the main variable and accounted for 7.92% of the total variance. 2) Education and frequency of pregnancy accounted for an additional 2.74% of the total variance. From the above findings, this study suggests the following : 1) Considering the lack of empirical support, the theroy of hardiness needs to be evaluated. 2) A valid, reliable and culturally appropriate instrument needs to be developed for Health Related Hardiness Scale. 3) There is a need for further study of hardiness in a broad variety of populations. 4) There is a need for comparative study correlation between hardiness and compliance with prenatal care in woman with normal and abnormal pregnancies

It has been noted that a genetic alteration of cells influenced by unhealthy lifestyle in addition to a series of other carcinogens increases the incidence of various neoplasmic diseases. Therefore the importance of a lifestyle that minimizes such an impact on health should be emphasized. Since stomach cancer, the most common neoplasmic disease in Korea, is related to personal lifestyle and as there is a possibility of its recurrence, patients with stomach cancer need to lead a healthy lifestyle. Also the quality of life which patients experience is negatively affected by the side effects of treatments and the possibility of recurrence. Therefore an effective nursing intervention to enhance quality of life and encourage healthy lifestyle is needed. The purpose of this study is to provide a basis for nursing intervention strategies to promote health and thus enhance quality of life. A hypothetical model for this purpose was constructed based on Pender's Health Promotion Model and Becker's Health Belief Model, with the inclusion of some influential factors such as hope for quality of life and health promoting behavior. The aims of study were to : 1) evaluate the effectiveness of patient's cognitive-perceptual factors on health promoting behaviors and quality of life ; 2) examine the causal relationships among perceived benefit, perceived barrier, perceived susceptibility and severity, internal locus of control, perceived health status, hope, health concept, self efficacy, self esteem health promoting behaviors & quality of life ; 3) build and test a global hypothetical model. The subjects for this study were 164 patients who were being treated for stomach cancer were approached in the outpatient clinic on a University Hospital. The data from the completed questionnaires were analyzed using Linear Structural Relationships (LISREL). The results of research are as follows : 1) Hypothetical model and the modified model showed a good fit to the empirical data, revealing considerable explanational power for health promoting behaviors(54.9%) and quality of life(87.6%) 2) Self efficacy and hope had significant effects on health promoting behaviors. Of these, hope was affected indirectly through self efficacy and self esteem. 3) Perceived health status, hope and self esteem had significant direct effect on the quality of life. Of these variables, perceived health status was the most essential factor affecting general satisfaction in life. 4) Self-efficacy, as a mediating variable, was positively affected by perceived benefit and hope. 5) Self-esteem, as a mediating variable, was positively affected by perceived health status and hope. 6) Hope was the main variable affecting self efficacy, self esteem, health promoting behaviors and quality of life. The derived model in this study could effectively be used as a reference model for further study and could suggests a direction for nursing practices

This study investigated dietary education and education satisfaction from the perspectives of academic ability improvement, psychological-emotional development, and self-respect. For this reason, empirical analysis was performed on the relationship between dietary education activity, education satisfaction, and self-respect. The purpose of this study is to appreciate the importance of dietary education, to focus the attention of researchers on dietary education and to provide fundamental materials. The results drawn from analysis are as follows. Firstly, it was discovered that the degree of dietary education has positive relationships with both academic ability improvement, and psychological/emotional development. Secondly, self-respect has positive relationships with academic ability improvement, and psychological/emotional development in terms of education satisfaction. Thirdly, after analyzing the influences of dietary education activity on self-respect, it was indicated that self-respect has a positive relationship with dietary education activity. Therefore, continuous and consistent dietary education needs to be performed at home, as well as at school, at the national level to establish appropriate dietary knowledge to teenagers, rather than simply delivering knowledge. It is also suggested that the education that can form self-respect be required.
