The main objective of this article is to investigate the existence of the lunar effect during the full moon period (FM period) and the new moon period (NM period) on the selected Islamic stock market returns and volatilities. For this purpose, the Ordinary Least Squares model, Autoregressive Conditional Heteroscedasticity model, Generalised Autoregressive Conditional Heteroscedasticity model and Generalised Autoregressive Conditional Heteroscedasticity-in-Mean model are employed using the mean daily returns data between January 2010 and December 2019. Next, the log-likelihood, Akaike Information Criterion and Schwarz Information Criterion value are analyzed to determine the best models for explaining the returns and volatility of returns. The empirical results have deduced that, during the NM period, excluding Malaysia, the total mean daily returns for all of the selected countries have increased mean daily returns in contrast to the mean daily returns during the FM period. The volatility shocks are intense and conditional volatility is persistent in all countries. Subsequently, the volatility behavior tends to have lower volatility during the FM period and NM period in the Islamic stock market, except Malaysia. This article also concluded that the ARCH (1) model is the preferred model for stock returns whereas GARCH-M (1, 1) is preferred for the volatility of returns.

Purpose: This study examined the effect of a self-help management program which strengthens self-efficacy on the self-efficacy and the activities of daily living(ADL) in stroke patients. Methods: A quasi-experimental nonequivalent control group, pre and post design was used. The subjects consisted of 47 stroke patients. Twenty-six patients were assigned to the experimental group and 21 patients were assigned to the control group. The self-help management program by strengthen self-efficacy and general hospital care were carried out on the experimental group. General hospital care was performed on the control group. The data was collected before and 5 weeks after the program. All subjects were questioned about the self-efficacy and ADL before and after the program. Results: The scores of the self-efficacy and ADL in the experimental group were higher than those in the control group. Conclusion: The self-help management program by strengthen self-efficacy is effective in increasing the self-efficacy and ADL. Therefore this program may be a useful intervention to increase the ADL in stroke patients.

A total of 11,395 animals were impounded in shelters in Seoul in 2013. The Animal Protection Division of the Seoul metropolitan government has annual contracts with local veterinary associations as well as Korean animal rescue and management organizations for providing shelter to animals, and collects monthly statistics from these groups. In 2013, the collected intake and outcome data for 25 districts were reviewed to analyze shelter capacity in terms of housing capacity (monthly daily average intake, required holding capacity, and adoption-driven capacity), staff capacity (staff hours required for daily care), and live release rate. Seasonal variations in the monthly daily average intake were observed, indicating that management of these shelters requires various strategies. This study was performed to analyze and interpret meaningful statistics for improving the efficiency of animal shelters in Seoul. However, inconsistent collection of animal statistics limited data compilation. Creation of a basic animal statistics matrix with reference to well-designed matrices from recognized professional animal shelters is essential. These complied statistical data will help plan for future animal shelter needs in Seoul.

Load Duration Curve(LDC) is a useful tool for analyzing water quality characteristics under various stream flow conditions. This study investigated the methods to identify impaired waterbodies in the assessment of water quality goal attainment by using LDC for the management of Total Maximum Daily Loads (TMDLs). Three methods were proposed. Non-typical regime exclusion method is a method to exclude water quality observations in the non-typical extreme flow conditions in order to minimize the influence of non-ordinary water quality. Flow regime weighted average method is a method to calculate weighted mean water quality instead of arithmetic mean in order to consider water characteristics properly on stream flow regime in addition to the effect of Non-typical regime exclusion method. Load exceeded interval comparison method is a method to compare the intervals between the attained and non-attained load duration periods on the LDC. The assessment of water quality goal attainment can be performed more reasonably and precisely considering water quality variations on stream flow conditions by applying these proposed methods.

The variation of streamflow is regarded as one of the most influential factors on the fluctuation of water quality in the stream. The characteristics of the variation should be taken into account in the plans for the management of Total Maximum Daily Loads (TMDLs). This study analysed and characterized spatial distribution and temporal variation of streamflow at each unit watershed in Guem-river basin. For the analysis of the distribution of streamflow, the type and the extent of the distribution were investigated for the unit watershed. For the analysis of the variation, short and long term changes of streamflow were examined. The result showed that most of the distributions were not log-normalized and the extent of variation tends to be greater at the unit watershed placed on the tributaries in the basin. A kind of margin could be granted to the unit watershed involving high variations so as to establish the water quality goal and load allotment more reasonably and effectively in view of whole waterbody.

Some regions and states, such as Wyoming, have harsh weather conditions, forcing most transportation projects to be completed under tight schedules. However, construction projects are not only delayed by weather conditions, but also delayed by other factors such as contractor's competency, resource availability, coordination issues, and safety. Also, the construction method, geographical location of the projects, and inability to follow baseline schedules accurately due to the contractor's resource allocation are also reasons for the delay. This paper discusses the main reasons for the delay in the public transportation projects based on Daily Work Reports (DWRs) from five different transportation projects of the last three years in Wyoming. This paper focuses on the inconsistencies of the contractor's schedules to complete the project according to the baseline schedule. First, the authors collected DWRs and baseline schedules from the Wyoming Department of Transportation (WYDOT). Second, the DWR data are compared against the baseline schedules to determine the reasons for delaying their significance. Finally, the paper presents the recommendations to mitigate the effects of delays on public transportation projects as well as to improve the documentation process of DWR data.

The purpose of this thesis is to investigate the information content of commercial paper credit rating changes of Korean firms. The result shows neither sinificant daily abnormal returns nor significant cumulative daily abnormal returns over the test window. This ind icates that commercial paper rating changes are not informative to investors. A sensitivity analysis conducted for the portfolio of subsample shows a similar result. This thesis, however, may contribute to the better operation of Korean financial market by providing several directions to establish credit-based financial transactions.

Purpose: The purpose of this study was to determine the effects of 5 weeks self-help management program developed by Kim et al. (2000-b) and reinforced with music therapy for post stroke patients. Method: This was pre-experimental study and the subjects were 14 post stroke hemiplegic patients at home who were registered at the Gunsan Health Center. The program was applied for five weeks and two hours for each session composed of the preparation step, the main step and the finishing step. The contents of the program were ROM exercise, daily activity training, risk factors and aftereffects, nutrition management and stress management. To collect data, all subjects were questioned before and after the application of the program. Collected data were analyzed through frequencies, percentages, Wilcoxen signed rank test and Cronbach's alpha using SPSS-WIN program. Result: After the application of the self-help management program, a statistically significant increase was observed in the subjects' ability to perform activities of daily living (p=.039), ability to perform instrumental activities of daily living (p=.005), self-efficacy (p=.001), self-care behavior (p=.001) and quality of life (p=.001), and a statistically significant decrease was observed in depression (p=.012). Conclusion: The present self-help management program was found to be helpful in improving the subjects' physical and psychological functions after they were attacked by stroke, so to be an effective nursing intervention strategy for post stoke patients. Future researches need to reinforce and materialize music therapy and to develop and apply a self-help management program that includes not only post stroke patients but also their families. In addition, it is necessary to expand the scope of subjects and apply follow-up management in order to continue self-help meetings.

The purpose of this study was to determine the effects of 5 weeks self-help management program on reducing depression, promoting Activity of Daily Livings(ADLs), Instrumental Activity of Daily Livings(IADLs), grasping power, hope and self-efficacy for post stroke patients visiting public health care centers in Seoul. This was pre-experimental study, and the subjects were 27 post stroke hemiplegic patients. The program was composed of five sessions and each session had health education on stroke, ROM exercise and recreation. Data were collected from May to November, 2000, and all subjects were asked to complete the Questionnaires, be measured vital signs and grasping power. Data were analyzed with frequency, percent, paired t-test, and Pearson's correlation coefficient using SAS(version 6.12) program. The results were as follows : 1) The scores of ADLs were increased from 27.04 to 28.22 after program, and that was statistically significant(p=.005). 2) The scores of IADLs were increased from 18.70 to 19.78 after program, and that was statistically significant(p=.004). 3) The grasping power of right hand were increased from 21.87kg to 26.93kg after program, and that was statistically significant(p=.002). But the grasping power of left hand were statistically insignificant(p=.919). 4) The scores of depression were decreased from 39.63 to 35.30 after program, and that was statistically significant(p=.030). 5) The scores of hope were increased from 30.89 to 34.15 after program, and that was statistically significant(p=.002). 6) The scores of self-efficacy were increased from 67.70 to 76.37 after program, and that was statistically significant(p=.000). According to the results of this study, the scores of Activity of Daily Livings(ADLs), Instrumental Activity of Daily Livings (IADLs), hope, and self-efficacy and the grasping power were improved and depression was reduced in post stroke patients participating in self-help management program. Therefore we recommend to use self-help management programs as a nursing intervention for the post stroke patient.
