A Method Of Analyzing Mandibular Movement, Richard B. Mccoy Jun 1973

A Method Of Analyzing Mandibular Movement, Richard B. Mccoy

Loma Linda University Electronic Theses, Dissertations & Projects

Mandibular movement is considered to be a fundamental factor in the study, analysis, and treatment of occlusion. For many years, dentists have realized that dental health depends upon the compatibility of mandibular movements and occlusion. This realization has led to the development of new methods and techniques for recording accurately and scientifically the movements of the mandible. In order for this data to be of scientific value, it must be stored in a usable form which is easily available for analysis.

The purpose of this research project was to develop a procedure for storing and recalling mandibular-movement information. Before such …


The Effect Of A Repressive-Inspirational Discussion Group On The Self-Esteem Of Selected Elderly Individuals, Rebecca Hollesca Gucilatar Jun 1973

The Effect Of A Repressive-Inspirational Discussion Group On The Self-Esteem Of Selected Elderly Individuals, Rebecca Hollesca Gucilatar

Loma Linda University Electronic Theses, Dissertations & Projects

This study was conducted to determine if the use of a repressive-inspirational discussion group has significance in changing the level of self-esteem of institutionalized essentially normal elderly individuals.

A review of literature indicates the need for a group method that can help in developing and maintaining self-esteem in the elderly. Different studies reveal the need for self-esteem in the aged. The development of self-esteem is necessary so that elderly individuals can cope with situations in daily living and maintain physical and mental health.

An experimental method was utilized in conducting this study. A sample of twenty elderly individuals was selected …


Selected Physiological Responses To A Back Rub, Norma (Ewing) Anderson Jun 1973

Selected Physiological Responses To A Back Rub, Norma (Ewing) Anderson

Loma Linda University Electronic Theses, Dissertations & Projects

The back rub, which has been an established part of evening patient care for many years, is given to promote relaxation and sleep as well as to promote skin care. Yet its place in modern nursing seems questionable. Today's nurse is less willing to practice using empirically established procedures.

There have been few investigations showing the effect of massage to the back and no studies have shown that a brief back rub, as given by nurses, promotes relaxation. In cardiovascular nursing there is some controversy as to whether or not the back rub causes stimulation to the cardiovascular system that …


An Investigation Of Cluster Analysis, John C. Klingel May 1973

An Investigation Of Cluster Analysis, John C. Klingel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Three cluster analysis programs were used to group the same 64 individuals, generated so as to represent eight populations of eight individuals each. Each individual had quantitative values for seven attributes. All eight populations shared a common attribute variance-covariance matrix.

The first program, from F. J. Rohlf's MINT package, implemented single linkage. Correlation was used as the basis for similarity. The results were not satisfactory, and the further use of correlation is in question.

The second program, MDISP, bases similarity on Euclidean distance. It was found to give excellent results, in that it clustered individuals into the exact populations from …


Analysis Of Case Histories By Markov Chains Using Juvenile Court Data Of State Of Utah, Soo-Hong Uh May 1973

Analysis Of Case Histories By Markov Chains Using Juvenile Court Data Of State Of Utah, Soo-Hong Uh

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this paper is to analyze juvenile court data using Markov Chains. A computer program was generalized with a single array orientation for analyzing realizations of a Markov Chain to the kth order within machine limitations. The data used in this paper were gathered by the Juvenile Court of the State of Utah for administrative purposes and limited to District II. The results from the paper, "Statistical Inference About Markov Chains" by Anderson and Goodman, were applied for testing hypotheses. The paper is divided into five chapters: introduction, statistical background, methodology, analysis and summary, conclusions.


The Nursing Process And Its Relationship To The Quality Of Nursing Care, Arlene H. Johnson May 1973

The Nursing Process And Its Relationship To The Quality Of Nursing Care, Arlene H. Johnson

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to determine the effect of the systematic use of the nursing process on the quality of nursing care. Quality nursing care was defined as being achieved when the patient's nursing care needs are identified and plans made to assist the patient with these needs.

It was hypothesized that the quality of nursing care would be improved by the participation of the team leaders in a series of classes on the nursing process. This improvement in quality nursing care would be evidenced by a higher correlation between the patient's needs perceived by the nurse and …


A General Lr(K) Parser Building Algorithm, Thomas Joshua Sager Apr 1973

A General Lr(K) Parser Building Algorithm, Thomas Joshua Sager

Mathematics & Statistics ETDs

The problem is to find an efficient algorithm that, given the productions of a context-free grammar G, will discover whether G is LR(k) for given k and if it is build an efficient parser for G . The algorithm is given in Section 8. It is essentially a synthesis of the best parts of Knuth's and DeRemer's algorithms. On simple LR(k) grarranars it yields a result equivalent to DeRemer's algorithm, and like Knuth's algorithm it will work on all LR(k) grammars.


Leadership Techniques In Groups With Chronic Schizophrenics, Judith L. Jensen, Leona W. Mcgrew Apr 1973

Leadership Techniques In Groups With Chronic Schizophrenics, Judith L. Jensen, Leona W. Mcgrew

Loma Linda University Electronic Theses, Dissertations & Projects

The study was designed to assess the level of anxiety experienced by chronic schizophrenic patients when two different methods of leadership were used in group therapy. A search of literature revealed suggestions for modification of leadership approach due to the tenuous anxiety tolerance of chronic schizophrenics but no studies were found directly related to the amount of anxiety resulting from different leadership approaches.

A structured group in which the leader maintained a directive role was compared with a nonstructured group in which the leader maintained a nondirective role in the group process. The randomized sample included five male and five …


The Effect Of A Training Program On Job Satisfaction Among Hospital Dietary Supportive Personnel, Alice E. Calkins Mar 1973

The Effect Of A Training Program On Job Satisfaction Among Hospital Dietary Supportive Personnel, Alice E. Calkins

Loma Linda University Electronic Theses, Dissertations & Projects

Steadily rising labor costs are forcing health-care institutions to give increased attention to meeting manpower needs. Dietary service management is recognizing the need for employees to be satisfied with their work, as well as the difficulty of providing adequate training for each employee. A study of the effect of a training program on job satisfaction should provide information relevant to more effective planning for the training and development of human resources within the hospital dietary service.

The purpose of this research was to determine the level of job satisfaction among hospital dietary supportive personnel; relate it to such factors as …


The Evaluation Of Glasser's Maximum Likelihood Method On Missing Data In Regression, Gayle M. Yamasaki Jan 1973

The Evaluation Of Glasser's Maximum Likelihood Method On Missing Data In Regression, Gayle M. Yamasaki

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Missing data in regression is often a problem to research workers because standard regression methods are applicable only to complete data sets. At present there are three general methods for solving the problem of missing data.

At first, the reduced data method, reduces the incomplete data set to a complete data set before analyzing. Although this method is very simple to apply, substantial amounts of information are sometimes lost when data is eliminated. This results in less precise estimates of the regression parameters.

The second method, generalized least squares, estimates the missing values through least squares techniques, thus obtaining a …


A Monte Carlo Comparison Of Nonparametric Reliability Estimators, Jia-Jinn Yueh Jan 1973

A Monte Carlo Comparison Of Nonparametric Reliability Estimators, Jia-Jinn Yueh

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

It is very difficult to construct a reliability model for a complex system. However, the reliability model for a series configuration is relatively simple. In the simplest case in which the components are mutually independent, the system reliability can be represented as follows:

Rs(x) = ∑ni=1Ri(x),

where Ri is the reliability for the ith component. It is also known that for moderate levels of system reliability for large systems, the component reliability must be high.

Extreme Value Theory indicates that under very general conditions, the initial form of the distribution function …


Integer Programming By Cutting Planes Methods, Sung-Yen Wu Jan 1973

Integer Programming By Cutting Planes Methods, Sung-Yen Wu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Linear programming is a relatively new, very important branch of modern mathematics and is about twenty five years old.

In this day and age, most planners and decision makers will acknowledge that some linear optimization problems are worth the expense and trouble to solve. Using linear programming technique as a tool to make decision plannes are able to greatly redice cost or increase profit for any project under consideration.

Since Dr. George B. Dantzig published his first paper on the simplex method in 1947, progress in that field has been rapid. Although the first applications were military in nature, it …


A Nonparametric Solution For Finding The Optimum Useful Life Of Equipment, Barry T. Stoll Jan 1973

A Nonparametric Solution For Finding The Optimum Useful Life Of Equipment, Barry T. Stoll

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

It is often the case that equipment used by industry must be replaced with new equipment from time to time either because frequent malfunctions make it too costly to repair, or because the equipment has simply worn out. The new equipment often has the nature of either malfunctioning soon after installation due to manufacturing defects, or functioning for an extended period of time because it is free of these defects. For this reason, equipment is often given a preliminary running called the burn-in which gives no useful output but merely tests for manufacturing defects. Also, after a given amount of …


Computer Programs Supporting The Teaching Of Statistics, Chien-Hwa Liu Jan 1973

Computer Programs Supporting The Teaching Of Statistics, Chien-Hwa Liu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

During the past few years there has been an increasing interest in developing computer packages to enhance the teaching of elementary statistics. The conventional ways of teaching statistics have used such devices as desk calculators, tables of functions, short-cut calculating formulas and electronic calculators, etc. to manipulate the involved computations. Electronic computers, in the past decade, have been broadly used in universities and colleges in many ways. It is only natural to extend the use of computers to the teaching function. Remote terminals can now be installed in any classroom and bring the computer to the students.


Canonical Analysis Of Several Sets Of Variables, Chong S. Kim Jan 1973

Canonical Analysis Of Several Sets Of Variables, Chong S. Kim

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Many procedures have been proposed for analyzing and describing multivariate dependence structure.

Partial correlation, multiple correlation, canonical correlation, principal component and factor analysis are used to analyze the dependence structures of a multinormal population.

For a partial correlation analysis it is necessary to decide which variables are to be correlated and which of the remaining variables must be held constant.

Multiple correlation demands that one variable be dependent upon some or all of the remaining variates.

For a canonical correlation, the variables must be collected into two or more sets. The factor analysis technique is for explaining the covariances of …

The Auditor And Statistical Sampling Techniques, Marilyn Metcalf Jan 1973

The Auditor And Statistical Sampling Techniques, Marilyn Metcalf

Honors Theses

"The auditor's overall objective is to determine whether the accounting process is free from material error." To complete his objective, the auditor must thoroughly analyze all aspects of the financial statements used in the accounting process in order to satisfy himself that they fairly represent the results of activity for the period under audit and of the financial position at the end of that period. If the volume of the transactions is great, time and economic factors may keep the auditor from making a 100 percent examination. Since a complete examination cannot be made, the auditor must choose a portion …
