Given the ongoing debate in many aspects of finance, more attention may need to focus on corporate R&D expenditures. This study empirically tests financial determinants of R&D expenditures for NYSE-listed and KOSPI-listed firms. Three major hypotheses were postulated to test for corporate R&D outlay. First, proposed variables such as one-year lagged R&D expenditures, market value based leverage, profitability and cash holdings showed significant influence on corporate R&D costs for the sample firms. Moreover, financial factors inclusive of squared one-year lagged R&D expenditures, the interaction effect between one-lagged R&D expenditures and high-growth firm, non-debt tax shield, Tobin's q and a dummy variable to explain differences in accounting treatment between the U.S. and Korea, revealed significant differences between the two samples. Finally, in the conditional quantile regression (CQR) analysis for the R&D-related variables in relation to corporate growth rate, it was found that the NYSE-listed firms had a statistically significant linkage between growth potential and one-year lagged R&D expenditures at lower quantile levels. This study may shed new light on identifying financial factors affecting differences between the U.S. market (as an advanced market) and the Korean market (as an emerging market) regarding the optimal level of R&D investments for shareholders.

A Discourse Analysis tool has been developed and has been applied in the cooperative group inquiry activities in order to derive the characteristics of elementary gifted students in science. We recorded and videotaped the whole group problem-solving processes where 4 elementary students worked together to solve given problems as a group for one year in a gifted education center attached to a university in Seoul. We analyzed recorded discourses using systemic functional linguistics with a focus on the structure of information and topic. The discourse analysis tool was developed with the cooperation of science education and gifted education experts. In discourse analysis, we focused on meaning development processes rather than grammatical analysis. Through application of newly developed discourse analysis tool, we confirmed that the tool is useful in understanding the characteristics of science-gifted elementary students. We also founded that the interaction between students has significant effects on problem-solving processes by comparing two students who showed contradictory features in the share of dialogue. In addition, the result suggested that we need to provide students with proper training for ways to communicate with others for effective science-gifted instruction.

This study examined the moderating effect self-rated health has on the association between grandparenting and depressive symptoms. The fourth wave (in 2012) of the Korean Longitudinal Study of Ageing (KLoSA) was used for the analyses (N=650). The Coarsened Exact Matching (CEM) method was applied in order to ensure randomness in the selection of grandparents who participated in grandparenting and those who did not. The dependent variable was depressive symptoms, the independent variable was grandparenting, and the moderating variable was self-rated health. Control variables were education level, age, household income, gender, marital status and life satisfaction. After matching data by CEM, weighted multiple regression was applied with STATA 13.0. Also, simple slope analysis and region of significance were performed to interpret the interaction terms. The results showed that self-rated health had a significant moderating effect. Specifically, for grandparents with high self-rated health, grandparenting was associated with a lower level of depressive symptoms. On the contrary, for grandparents with low self-rated health, there was no difference depending on whether they participated in raising grandchildren. Based on these results, we discussed the need for consideration of self-rated health for grandparents who participated in grandparenting.

ESG, which stands for Environmental, Social, and Governance, becomes a keyword in managing a company as it becomes an "indicator" that judge companies. Since the environment has suffered so much damage for economic development, it is now to reflect the enormous environmental costs of the future in the management standard rather than the immediate financial benefits at the expense of the environment. Compared to the days when corporate social responsibility (CSR) was discussed, ESG management has improved significantly as it requires practice beyond the declarative level, but the level of consideration for the environmental field is still not high. There may be many backgrounds, but the biggest problem may be the lack of understanding for other fields. Accordingly, this study aims to inform corporates of the need for investment in the environmental field by explaining ESG reviewed in the environmental field and ESG management required in the environmental field. Furthermore, another purpose is to inform them that ESG management is a win-win strategy that can have a meaningful effect not only in the environmental field where investment is received but also in terms of companies by explaining the benefits that companies can gain through this. To reach this goal, this study proposed a method of restoring a damaged ecosystem based on corporate investment, evaluating its effects based on carbon absorption capacity, and using it as a means of carbon neutrality practice as well as ESG management performance of a company.

In our society today, a variety of medical caring system, along with a scientific development in the area of oriental medical science plus national demand, has increased the augmentation and the opening of oriental wards and hospitals (Han Bang), which has come to create an additional requirement of nursing activity at oriental medicine wards should be different from that of the general wards or the same as the other. In view of this, various studies need to be made in this connection. The purpose of this study is to comprehend the number of nurses who want to work at oriental medicine wards and measure job satisfaction in nursing as compared with those working at general wards so as to provide basic materials for future assignment and supplementary training for the nurses. An attempt was made to contribute toward nursing administration on the one hand improving nursing training course on the other hand. A total of 72 nurses currently working at two oriental medicine hospitals available in Seoul and 82 general nurses were selected for this study using the questionaire from December 1993 to January 1994. An instrument for the study was based on the measurement of work satisfaction developed by Paula L. Stamps including 37 questions complemented by Kim for revision (1993) and 14 questions regarding general characteristics and oriental medicine wards. The instrument to test dependability showed Cronbach's=0.7711. The collected data have been processed by computer package SPSS. General characteristics of the two groups and the matters involved in oriental medicine wards were calculated into real figure and percentage an similarities between the two groups were analyzed by t-test and F-test according to the characteristics of variables. The comparative test on work satisfaction among the two groups including general characteristics and work factors were conducted by t-test and F-test. The major findings as a result of the study are as follows : 1. As general characteristics, age group of $26{\sim}30$ years are more than any segment of age. As to marital status, the number of those in single status is slightly higher than the married. Approximately 80% of them are graduates of nursing schools and nursing colleges. They are mostly in service for one to three years. There is no significant difference between the two groups. 2. The number of those who want to work at oriental medicine wards represents 40.3% against 58.4%, being in favor of general wards. 3. The reason for service at oriental medicine wards is that "there is room for potential research" which happened to rank first, followed by "easy job," "good working atmosphere" and "growing interest in oriental medicine." 4. Work satisfactions among nurses who work at oriental medicine wards prove greater than that of nurses who work at general wards. 5. Work satisfaction between the two groups by work factors is reflected with significant difference statistically on task requirement, interaction and doctor-nurse relationships. 6. The general charcateristics and the work satisfaction by work factors prove that there are significant difference in age, marital status, education and the period of work. They tend to be more satisfied with the work as they grow in age. Significant differneces are found in the work factors such as autonomy, adiministration and professional job in the relationship with doctor-nurse. As to marital status, the married are more satisfied than the unmarried. There are significant differneces in the factors respecting administration and doctor-nurse college graduates are highly satisfied with task requirement. However, satisfaction with the professional level has proven the highest degree for those having master degree. The period of work and satisfaction : There are significant differneces in task requirement, administration, interactions, professional level and doctor-nurse relationships. As a general rule, the degree of satisfactions is in proportion to the lengrh of service. The following conclusions are drawn based on the fndings mentioned above. Even though the work satisfaction of the nurse who work at oriental medicine ward is relatively high, it is desired that personal consultation be given as to disposition of nurses when they are assigned to oriental medicine wards. It is also recommended that lectures on oriental medicine be conducted through supplementary training and/or basic nursing course in order that they may be motivated for ingenious activities with an increasing sense of self-esteem which will eventually enhance positive changes for the patients who are in need of oriental medicine nursing and for the medical teams. In addition, joint reseaches involvingclinical care and education should be in constant process for unique and scientific development for those who are subject to oriental medicine nursing care.

This study was conducted to investigate and compare the degree of professional self -concept (PSC) of the psychiatric mental health nurse practitioners (PMHNP) in hospitals and public health centers and to identify the factors predicting PSC of them, in order to provide basic data for developing PSC increasing program PSC. The 355 PMHNP were sampled from the university or general hospitals. mental hospitals, community mental health centers and public health centers across the country. The scales used in this study were PSCNI by Arthur (1990), PSI by Heppner & Petersen (1982) and the Index of work satisfaction by Slavitt et al. (1978). The results of the study were as follows : 1. The average item score of PSCNI of PMHNP in hospitals was $2.83\pm0.27$, and that of PMHNP in public health centers was $2.76\pm0.28$. There was significantly different between two groups (p=0.0202) 2. A comparison of the scores for the dimensions of the PSCNI were as follows ; the mean item score of professional practice of nurses in hospital was $2.90\pm0.30$, and that in public health centers was $2.83\pm0.35$. There were significant differences between two groups in the scores of professional practices (p=0.0315), leadership (p=0.0071) and skills (p=0.0231). 3. There were significant differences between two groups according to education (p=0.0057) with no significant interaction effect of group and education. 4. Job satisfaction (JS) was the highest factor predicting PSC of PMHNP in hospitals $(34.5\%)$, and problem solving inventory score (PS) was the highest factor predicting PSC of PMHNP in public health centers $(33.6\%)$. JS and PS accounted for $42.6\%$ in PSC of PMHNP in hospitals. and PS, JS, age, marital status, religion, and career accounted for $57.6\%$ in PSC of PMHNP in public health centers. In the light of these results. to gam the professional self-concept. nurses should be educated continuously through role modeling in clinical nursing and research. Also, nurse educators and administrators need to develop programs and policies to increase professional self-concept of nurses, particularly of community PMHNP.

PURPOSE : The purpose of this study is to know the ability of detecting malignant tumor tissue by Tl-201 scan, and to compare with that of Tc-99m-MIBI and Tc-99m-MDP scan. MATERIAL AND METHODS : Between February 1994 and December 1995,38 unselected patients with various bone pathologies were studied prospectively. Eighteen had malignant bone and soft tissue pathologies, while twenty had benign. All patients were studied with Tl-201, Tc-99mMIBI and Tc-99m-MDP scan prior to surgical biopsy. PICKER Prism 2000 gamma camera with high resolution parallel hole collimator was used for scanning. To avoid the interaction of isotope, the early(30min.) and delayed phase(3hrs.) of Tl-20l scan was performed first and Tc-99m-MIBI scan was performed after 30 minutes, and then Tc-99m-MDP scan 48 hours later. The scan images were visually evaluated by a blinded nuclear medicine physician. We could find true positive, true negative, false positive and false negative by the comparison of results with those of biopsy. We calculated positive and negative predictive value(%), sensitivity(%), specificity(%) and diagnostic accuracy(%) of each scan. RESULT : The results of each scan were 85.7, 100, 100, 85, 92.1% in Tl-201, 81, 94.1, 94.4, 80, 86.8% in Tc-99m-MIBI and 50, 66.7, 88.9, 20, 52.6% in Tc-99m-MDP scan. As a conclusion, Tl-201 scan was the most specific and accurate method for detecting malignant tumor tissue. Tc-99m-MIBI scan was also good for malignant tumor searching. CONCLUSION : With our results, we can use Tl-201 scan to differentiate benign from malignant tumor, and to evaluate the response of preoperative chemotherapy or radiotherapy, and to determine the residual tumor or local recurrence. For the better result, we need to have a more detail information about false positive cases and a more objective and quantitative reading technique.

This study was done for the purpose of analyzing the job-satisfaction and its depressive factors in human relation of operating room nurses of university hospital. Therfore, it makes an offer the basic data to help the resolution and prevention of the problems in operating room nurses. Furthermore, this study was conducted in order to find out some kinds of scientific data for the better control of depressive factors of job-satisfaction expressed by the operating room nurses. The structred questionaire reports of 246 operating room nurses who were employed in 5 different university hospitals which have over 1, 000 beds located in Seoul, Korea were used, which wer collected from August 24th to August 30th of 1992. The author visited supervisors of operating room in each university hospital and explained the aim of this study. The most of them(90.0%) answered to the questionaires. Analysis of the collected data were done by mean, standard deviation, percentage, t-test, F-test, Q-test, correlation analysis, one-way ANOVA.and stepwise multiple regression analysis. Major findings of this study were as follows: 1. The job of the operating room nurses were remarkably related with the satisfaction in human relation, which was defined as the behavioral job with thoughtful action rather than with mechanical action. However, the degree of satisfaction in human relation with personnel in other departments was found to be the lowest and its the main depressive factors were appeared due to the absence of interaction and uncooperative attitudes. Therefore, it was required that the members of other job need more cooperative attitude to the actual works in the operating room nurses. 2. The depressive factors in the satisfaction degree of human relation with offical seniors wer significantly related with their irresponsibility and partialness. Moreover, the job attitude of the operating room nurses is abundantly required to be improved, 3. The depressive factors in the satisfaction of human relation with medical doctors were significantly related with their insincerity and the class-consciousness. It is clearly suggested that the medical doctors do more cooperative behaviors for the jobs of the operating room without the suggested that the medical doctors do more cooperative behaviors for the jobs of the operating room without the superiority feeling of class-consciousness. 4. There was a significantly positive association between the satisfaction degree of human relation of the nurses with the following charateristics. (1) The registered nurses which had a tendency to be satisfied about the registered nurses' job. (2) The registered nurses which had a tendency to be a technique-aptitued in the motivation of the registered nurses'job. (3) The registered nurses which had a tendency to be satisfied about the total hospital working carrier and the aspects of old ages. Finally, these findings indicated that the operating room nurses should require the professional education courses associated with a high-development techniques and setisfaction in their jobs.

The purpose of this study was to determine whether there are differences in the verbal interactions of earth science gifted depending on their communications structures and group status in small group activities. To this end, a small group activity was conducted to measure the density of the earth, and 8 small groups were selected, including 4 co-ownership type and 4 monopolistics type groups with different communication structures. And then, the framework was developed for analyzing verbal interactions to compare the differences in characteristics between small groups. The results are as follows. First, regardless of the communication structures, there were showing a simple pingpong-type communication structures for all small groups. Second, negative interactions such as 'restraint', 'command', 'complaint', and 'lack of confidence' predominantly appeared in all small groups. Third, the students in the status of out-lookers in small groups were mainly verbal interactions, such as instructing the other person, acting against the other person's actions, and expressing dissatisfaction with the attitudes and abilities of members. Therefore, teachers should guide students to use higher-level verbal interactions in their group activities in small group activities, and engage in students communication to prevent negative interactions from occurring. The teachers also need to check the level of achievement for students in the status of out-lookers in advance and guide them to participate more actively in small group activities. This study is meaningful in that it can be sued to design teaching and learning to improve students' problem solving and communication skills.

A mirror is a familiar tool for human beings who have been seeing themselves through it for a long time since it was created. As evolving Digital Technology, many approaches about digital mirrors which reflect not only the light, but also the information have been studied. Traditional mirrors on the wall do not need any special control to perform their automatic visual feedbacks, reflecting lights. On the contrary, digital mirrors can actively provide more information to the user than the traditional ones. In this paper, we propose an active digital mirror system of which functions are changed according to the user-mirror distance. First of all, we investigated users' behaviors on mirrors and categorized the interactions by user-mirror distance. Based on the previous result, we designed the user interface of the mirror, and developed a prototype which has three recognition modules: a distance measuring module using infrared sensor arrays, a user recognition module by computer vision technique, and a control perception module using infrared sensor grid. In addition, the next steps for improving the user-centered digital mirror system, and the possibility for developing a mirror-shaped computer system were suggested.
