The powers of some tests for independence hypothesis against positive (negative) quadrant dependence in generalized Farlie-Gumbel-Morgenstern distribution are compared graphically by simulation. Some of these tests are usual linear rank tests of independence. Two other possible rank tests of independence are locally most powerful rank test and a powerful nonparametric test based on the $Cram{\acute{e}}r-von$ Mises statistic. We also evaluate the empirical power of the class of distribution-free tests proposed by Kochar and Gupta (1987) based on the asymptotic distribution of a U-statistic and the test statistic proposed by $G{\ddot{u}}ven$ and Kotz (2008) in generalized Farlie-Gumbel-Morgenstern distribution. Tests of independence are also compared for sample sizes n = 20, 30, 50, empirically. Finally, we apply two examples to illustrate the results.

The present investigation is an attempt to create an optimized protocol for a bactericidal modality of different powers of He-Ne laser radiation to eliminate periodontitis disease causing bacteria from dental plaques. Periodontitis is most prevalent infectious disease of men and caused by a limited number of Gram negative oral bacteria. Porphyromonas gingivalis and Streptococcus sanguis are the important bacteria responsible for periodontitis diseases. Effect on periodontitis disease causing bacteria were produced by the exposure of different powers of He-Ne laser light i.e. 9 mW, 17 mW and 26 mW of red colour of wavelength 632.8 nm in two different periods of time i.e. 10 min. and 20 min. in the presence of dye Methylene blue (MB) used as a photosensitizer. The results have been shown in terms of percentage inhibition of colony forming units (cfu.) of bacteria. This study has shown that maximum inhibition of cfu. were observed in Laser+MB-20 min. exposure time. This inhibition was followed by Laser+MB-10 min., but minimum inhibition was seen in Laser only at 10 min. exposure. In case of effect of methylene alone on the cfu. of bacteria, it was seen that MB have not shown more inhibition of cfu. and it had shown that the no. of cfu. are very similar to that of control. The above observation of the present study was seen in case of every 3 different type of used powers of laser for both the bacteria. Maximum percentage inhibition of cfu. were seen in case of 26mW powers of He-Ne laser, which was 67. 28% to 61.42% for Porphyromonas gingivalis and Streptococcus sanguis respectively. So, increasing the power of laser (safe range for dentistry is 3-30 mW) under conditions shows an increased percentage inhibition of cfu. Thus the present investigation may be a useful adjunct with mechanical debridement in the prevention of recolonization of subgingival lesions by pathogenic microorganisms which are harmful and drug resistant.

The aim of this study is to analyze the meaning of Korean elders' reminiscences by analysing korean novel literature from 1930s to 1990s. The results of this study are as follows : The moaning of elders' reminiscences are the reflecting on their life, conquesting the excessive fondness the regrecting, the pursuiting of the powers, the pursuiting of the love(Jeong) and the conformation of their exsistence. Elders have tried to examine their life through reflection on their life tha? they did not live good life as son and daughter for parents and as parents for children and that they have foolishly lived, on dream that they did not come true, on their learning that they did not unsatisfied. But elders conquest the excessive fondness. They have felt their limitations of power in the conflict of human relation, the economic matter and the difficult predicament, and have finally accepted their life as it is by conquesting from their tenacity. It is dynamically found that both the reflecting on their life and conquesting of the excessive fondness. And they pursuit the powers. It means the pursuit of the vital powers, the vigorous powers and the competency, Elders have pursuited their vitality, vigor and competency through their reminiscences and have wanted to be recognized by others as a powerful being. These have dynamic and compounded aspects. Elders have pursuited the purely love (Jeong) through their reminiscence togather with their sisters and brothers. And the confirmation of their exsistence refer to through their own situation of health, condition, children, neighbourhood and doing their duty as a human. Elders have confirmed the present value of their being through the reflecting the present, past self, other men around themselves, children, neighborhood and the doing their human duty as a good men. Therefore the results of this study can offer new view on the elders' reminiscences that we have to understand them as a process as what they are, escaping from the simple logic that elders' reminiscence have a positive or a negative effects. Also, this study which have examined the natures of Korean elders' reminiscences can cast a new light on elders' nursing proper for Korean culture.

This work describes a preliminary investigation to a learning model based on cybernetics and radical constructivism. To achieve this purpose, main ideas of cybernetics, i.e., negative feedback, difference, self-regulation, equilibrium, and purpose-directed behavior was analysed under radical constructivism. Powers' model, which consists of hierarchically arranged negative feedback systems, is introduced into this work. This was based on the claim that living organisms behave to control perceptions. By adding the notion of scheme from the view of radical constructivism, a learning procedure, which consists of six steps, was suggested in this work.

The phrases such as elders' powerless soliloquy or stammering and their positions unadjusted to the real world are, so far, one of negative views on elder's reminiscences. In other words, it means that elders can get psychological consolation from the getting themselves absorbed in their past. The starting point of this study is, however, that elders' reminiscence are their own mode of the existence. This dissertation is studied through Van Manen's phenomenological research method. The aim of this study is to examine the nature of Korean elders' reminiscences by both observing and describing the reminiscing content in everyday life of elders. The research participants consist of the ten elders who are community elders, hospitalized elders and nursing home residents. The period of the research is about a year from Jan., 1996 to Feb., 1997. The results of this study are as follows : The natures of elders' reminiscences are the regrecting on their life, mitigating the regrects, the confirmation of the powers and the confirmation of their life's mark. The regrecting on their life is the starting point of elders's reminiscences. Elders have tried to examine their life through reflection on their life that they did not live good life as son and daughter for parents and as parents for children and that they have foolishly lived, on dream that they did not come true, on their learning that they did not unsatisfied. But elders mitigate the regrects. They have felt their limitations of power in the conflict of human relation, the economic matter and the difficult predicament, and have finally accepted their life as it is by conquesting from their tenacity. It is dynamically found that both the regrecting on their life and mitigating of the regrection. And they pursuit the powers. It means the pursuit of the vital powers, the vigorous powers and the competency. Elders have pursued their vitality, vigor and competency through their reminiscences and have wanted to be recognised by others as a powerful being. These have dynamic and compounded aspects. The confirmation of their life's mark refer to through their own situation of health, condition, children, neighbourhood and doing their duty as a human. Elders have confirmed the present value of their being through the reflecting the present, past self, other men around themselves, children, neighborhood and the doing their human duty as a good men. Therefore the results of this study can offer new view on the elders' reminiscences that we have to understand them as a process as what they are, escaping from the simple logic that elders' reminiscence have a positive or a negative effects. Also, this study which have examined the natures of Korean elders' reminiscences can cast a new light on elders' nursing proper for Korean culture.

Purpose: The study was conducted to compare the values of auto-refraction, manifest refraction and cycloplegic refraction in school-aged children. Methods: One hundred five myopic school children ranged from 6 to 14 years old (210 eyes, $10.28{\pm}1.59$ years old) were recruited and noncycloplegic auto-refraction (AR) and manifest refraction (MR) were conducted and then underwent cycloplegia and refractive status (CR) again with the auto-refractometer. Results: Refractive powers measured by AR, MR, and CR were highly correlated. However, spherical and cylindrical powers of the subjects measured by AR were measured higher negative power than in CR (p<0.001). From 210 eyes, the discrepancy rate in the spherical and cylindrical powers were 40 eyes (19%) and 19 eyes (9%) of the total subjects, respectively and the differences between noncycloplegic and cycloplegic refractions were higher with the spherical and cylindrical powers increasing. Conclusions: The use of the autorefractometer in children with negative spherical power without cycloplegia may overestimate the actual myopia that subjective refraction is the most important in prescription for the eyeglasses and regression equations would be used to prognose the cycloplegic refraction from the auto-refraction as the basic data for the subjective refraction.

This paper is concerned with the applicability of the chi-square approximation to the six disparity statistics: the Pearson chi-square, the generalized likelihood ratio, the power divergence, the blended weight chi-square, the blended weight Hellinger distance, and the negative exponential disparity statistic. Three dimensional contingency tables of small and moderate sample sizes are generated to be fitted to all possible hierarchical log-linear models: the completely independent model, the conditionally independent model, the partial association models, and the model with one variable independent of the other two. For models with direct solutions of expected cell counts, point estimates and confidence intervals of the 90 and 95 percentage points of six statistics are explored. For model without direct solutions, the empirical significant levels and the empirical powers of six statistics to test the significance of the three factor interaction are computed and compared.

All human being can not exist by oneself That is, all human being depend on intimate attachment for their survival. Physical and psychological powers are prerequisites fir one's survival and these serve important functions hi interpersonal relationships. There are two kinds of powers. One is positive power which helps one survive effectively. Another one is negative power which disturbs one's effective survival. In this paper, the author reviewed the precept of 'trust' which is described in 'Bible' and oriental classical books such as 'The Analects of Confuicus' and 'Tao Te Ching' etc. and tried to integrate this precept with the importance in everyday life, 'How to communicate' is closely related to 'trust' and one's speech is closely related to one's thinking or emotion. Thus in order to keep trustful communication, one has to introspect oneself to understand one's own emotional reaction.

This study is to understand and to describe the power that a nurse experiences on nursing practice and then. to present a basic data for nurse's power-development, power improving and empowering. Ethnography was used to understand and to describe experience on exercising various powers occurred on nursing practice. and to analyze and to understand the meaning of a nurse's power. The objects was nurses. Ten nurses who have more than three year's experience were selected as objects from Cuniversity's hospital in Seoul from May of 1996 to August of 1997 through in-depth interview. participant observation, and phone interview. Instruments werw a portable recorder and field notes. I described a case appeared in a data using Agar's 'Pencil and scissors' method right after collecting materials. Then, Idescribed a theme discovered commonly. Followings are the results of the study. 1. There were three categories of relationships with main objects when nurses exercised their power on their practices: a therapeutic caring relationship with patients, a relationship of companion, vertical cooperation, and a constituent person with a doctor, and a relationship of cooperation, and a constituent person with administrative workers and medical technicians. 2. There were many types of nurse's power, tactics and various patient's responses about them. 1) Types of nurse's power to patients were giving information, controling environment, helping for cure, emotional support, and performing discretion. 2) Nurse's tatics for performing power were positive tactics neutral tactics, and negative tactics. 3) Patient's responses were appeared as compliance and noncompliance. Compliance were agreeing. taking nurse's advice, trusting, understanding, being admitted, exposuring himself, and appreciating. 3. There were types of nurse's power and performing tactics. 1) Types of power to a doctor were advice, informing, demanding and mediation. 2) Performings of tactics to a doctor were positive tactics, neutral tactics, and negative tactics. 3) Doctor's responses were appeared as accepting and unaccepting. Acceptings were taking in and appreciating, and unacceptings were denying nurse's advice and authoritative. 4. There were types of nurse's power and tactics about administrative workers and medical technicians and responses about them. 1) Types of power about administrative workers and medical technicians were suggestions and demands. 2) Power performings tactics were positive tactics.neutral tactics, and negative tactics. 3) Responses of administrative workers and medical technicians about nurse's power performing were appeared appeared as accepting and unacce pting. Acceptings were taking in, and unacceptings were denying. Therefore, it can be said that types of nurse's power and performing tactics on nursing practice and nurse's power based on responses of a patient, a doctor, an administrative worker, and a medical technicians are power or influence for agreeing, taking advice, trusting, understanding, exposuring himself, appreciating, and taking in to objects. The results of this study helped to understand nurse's power. I expect that this study will improve nure's power by using expert power, referent power, and legitimate power effectively among powers acmpanied with the origin and that nurses make ef-ort to improve professional knowledge and human nature so that they use this study as a chance to develope expert nursing practice.
