Purpose: The purpose of this study was to compare motivation for rehabilitation, family support and adherence to rehabilitation and identify factors predicting adherence to rehabilitation between depressive and non-depressive stroke patients. Methods: Stroke patients admitted to rehabilitation hospitals (n=159) participated in the study. Data were collected through self-reported questionnaires including general characteristics, depression, motivation for rehabilitation, family support and adherence to rehabilitation. The data were analyzed by descriptive statistics, t-test, $x^2$ test, Pearson correlation coefficients and logistic regression using the SPSS/WIN 21.0 program. Results: 62.9% of the subjects were identified as depressive patients. Motivation for rehabilitation (F=48.18, p=.020) and adherence to rehabilitation (F=9.68, p=.002) in depressive stroke patients were significantly lower than non-depressive stroke patients. Family support also in depressive group was lower than non-depressive group but there was no statistical significance (F=2.35, p=.127). Motivation for rehabilitation (OR=11.46), family support (OR=1.05) and onset period (less than 2 year)(OR=3.61) predicted the good adherence to rehabilitation in depressive stroke patients. Conclusion: The results of this study indicate that health professionals need to identify factors affecting adherence to rehabilitation and provide a nursing intervention considering the depression especially when caring for stroke patients.

This study distinguishes the aging population as young-old and old-old women. It examines the difference of each variable between young-old and old-old women. Also, it examines the effect of physical, psychological, social, economic and environmental factors on the quality of life for older adults in both groups and compares the effects on the quality of life between both groups. The sample of this study is collected from Daegu and Kyungbuk province and the sample size of this study is 310. As statistical method, t-test, $X^2$ and hierarchical multiple regressions are used. As demographic factors, age, marital status, income and education are controlled. The research results show that marriage, perceived health, self-esteem and social support are important factors of affecting on the quality of life for both groups. However, for young-old group, the perceived economic hardship and the receipt of social welfare affect negatively and social participation affects positively on the quality of life. On the other hand, for old-old group, informative social role affects positively and social participation affects on the quality of life negatively.

The most widely used data mining technique is to explore association rules. This technique has been used to find the relationship between each set of items based on the association thresholds such as support, confidence, lift, etc. There are many interestingness measures as the criteria for evaluating association rules. Among them, confidence is the most frequently used, but it has the drawback that it can not determine the direction of the association. The net confidence measure was developed to compensate for this drawback, but it is useless in the case that the value of positive confidence is the same as that of negative confidence. This paper propose a attributably pure confidence to evaluate association rules and then describe some properties for a proposed measure. The comparative studies with confidence, net confidence, and attributably pure confidence are shown by numerical example. The results show that the attributably pure confidence is better than confidence or net confidence.

Association rule represents the relationship between items in a massive database by quantifying their relationship, and is used most frequently in data mining techniques. In general, association rule technique generates the rule, 'If A, then B.', whereas negative association rule technique generates the rule, 'If A, then not B.', or 'If not A, then B.'. We can determine whether we promote other products in addition to promote its products only if we add negative association rules to existing association rules. In this paper, we proposed the negatively pure association rules by negatively pure support, negatively pure confidence, and negatively pure lift to overcome the problems faced by negative association rule technique. In checking the usefulness of this technique through numerical examples, we could find the direction of association by the sign of the negatively pure association rule measure.

Mandatory use of resident registration number in Korean websites is likely to result in an violation of privacy. The Korea government introduced i-PIN (Internet Personal Identification Number) to solve this problem in Oct of 2006. But the implementation of i-PIN has failed to decrease violation of privacy. Therefore, we must open our eyes to problems of i-PIN and the importance of privacy protection. This study analyzes the policy failures of i-PIN and considers countermeasures for protecting privacy on the Internet, and explores policy alternatives to secure privacy on the Internet by analyzing the implementation process of I-PIN. In conclusion, this study stresses the urgent need for a well-thought-out policy in order to solve the problems of i-PIN on the Internet. It expects that the i-PIN will make a big stride for the realization of secure electronic government.

In this study, poly(arylene ether sulfone) (PAES) having thermal stability and excellent mechanical properties was synthesized to be useful for the matrix of anion exchange resin. $1^{\circ}$-Aminated poly(arylene ether sulfone) ($1^{\circ}$-APAES) was prepared by reduction reaction after lithiation of PAES. Then $3^{\circ}$-APAES was Prepared by alkylation of the amino group of $1^{\circ}$-APAES. The structures of PAES and APAESs were confirmed with FT-IR and $^1H-NMR$ spectroscopy. Also, thermal properties of the resins were characterized by DSC and TG analysis. The introduction of amine groups in PAES resulted in the increase of glass transition temperature and decrease of initial thermal degradation temperature. The ion exchange capacities of $1^{\circ}$-APAES and $1^{\circ}$-APAES were 1.19 and 1.45 meq/g, respectively.

Pedicularis growing at Mt. Halla of Jeju Island is known as an endemic species of P. hallaisanensis Hurusawa. On the other hand, the plant is morphologically similar to P. amoena, P. spicata, and P. verticillata in gross morphology, so the taxonomic treatment of the taxon remains controversial. To clarify the taxonomic position of the plants, we examined external morphological characters and nuclear ribosomal DNA ITS sequences for P. hallaisanensis and its related species. The plants of Mt. Halla are clearly different from P. amoena and P. verticillata in the morphology of calyx lobes, the length of galea and lower lip, density of glandular hairs on plants, presences of the radical leaves after anthesis and molecular data. However, P. hallaisanensis is not clearly separated from P. spicata distributed in N. E. Asia on external morphological characters and DNA sequences of internal transcribed spacers. In this study, the morphological and molecular data suggested that P. hallaisanensis should be merged into the former species.

This study is to examine the relationships between emotional labor, job stress, and job burnout of staff accountants. The results of the analysis are as follows. First, frequency of emotional display has a negative impact on job stress, but emotional dissonance is not associated with job stress statistically. And all types of emotional labor(emotional display, emotional variety, emotional dissonance) have no significant effects on job burnout. Second, all types of emotional labor have no significant impacts on job burnout. Third, full mediation by job stress is proved in the relations between frequency of emotional display and job burnout and between emotional variety and job burnout. But emotional labor doesn't directly impact on job burnout but it influences job burnout via job stress indirectly. These results provide a meaningful framework and theoretical basis for future research on emotional labor, job stress, and job burnout.

This study is to evaluate the public drinking water service systematically, to improve customer satisfaction level, also overcoming the limitations of the existing method often relying on the satisfaction measurement subjectively. Thorough the rigid quality control of the service and its effect on civil affairs administration, we conclude that quality of the public service has an influences on the customers' satisfaction, which play a role to intensify the confidence and support of the civil administration by its appropriate management. Thus quality control management itself has its own value in that the satisfaction and confidence of the service result from the quality. The new model can be utilized as a Service Quality Index for the public drinking water service. To enhance the customers' satisfaction and confidence of the water suppliers, it is very useful that they reflect the customers' needs exactly through the service quality control regularly.

The (polymer/carrier) composite membranes for separating the metallic ion have been prepared by the water cast-method. The morphology of these membranes was affected by the physical properties of the spreading solution. The surface tension of the (polymer/18-crown-6) composite solution was decreased with increasing the concentration of 18-crown-6 compound and the surface tension of polymer solution decreased the following order PVC>PS>CA. The viscosity of CA solution decreased with increasing the contents of the 18-crown-6 compound, but PVC and PS solutions showed no significance changes according as the concentration of 18-crown-6 compound. In the composite solutions, the spreading ability was improved by' the cyclic 18-crown-6 molecules which acted as an electric buffer and diminished the intermolecular force between the polymer chains. The (polymer/18-crown-6) composite membrane was more uniform than that of the mono polymer membrane on the coagulation state of polymer, and the top and bottom sides of membrane showed also the more smooth structure according as the concentration increment of 18-crown-6 molecule.
