The purposes of this study were to find out the effects of hospice care for the quality of life of the terminally - ill patients and to analyze the relationship between the effect of hospice care and the general characteristics of subjects. The subjects of the study were 32 terminally - ill patients hospitalized in the two general hospitals in Seoul, which have the hospice care unit. The data were collected using the questionnaire with interviews. They were done from Sept.28, 1989 to March 20, 1991. The tools used for the research were 17-item questionnaire regarding general characteristics, 42-item questionnaire about the quality of life (11- item for physical, 16 for psychosocial, and 15 for spiritual). The questionnaires were to measure the duality of life by means of the measure instruments of Betty R. Farewell(1989), Stein Kaasa(1988), Palm Pamela(1987), and Hwa-sook Choi(1987). 42 items were used after pre-test. In accordance with each purpose in this study, frequency and percentage were used on the general characteristics of subjects. ANOVA, t-test, and Pearson correlation were employed to evaluate the general characteristics of subjects and different level of quality of life before-and-after hospice care. The results of the study may be summarized as follws : 1. The effects of hospice care. Main Hypothesis : “The quality of life of the terminally - ill patients will be different from before-and-after hospice care” was supported(t＝6.82, df＝31, p＝ .000). Sub Hypothesis 1 : “The quality of life of the terminally - ill patients in the physical aspects will be different from before - and -after hospice care” was not supported(t＝0.07, df＝31, p＝ .946). Sub Hypothesis 2 : “The quality of life of the terminally - ill patients in the psychosocial aspects will be different from before-and-after hospice care” was supported (t＝4.69, df＝31, p＝ .000). Sub Hypothesis 3 : “The quality of life of the terminally - ill patients in the spiritual aspects will be different from before-and-after hospice care” was supported(t＝6.64, df＝31, p＝ .000). 2. Relationship between the general characteristics of subjects and the effects of hospice care. (1) The more the number of family, the higher the quality of life in the psychosocial aspects. (2) The higher the age of the patient, the lower the quality of life in the psychosocial aspects. (3) The high educational level of patients enjoy the high quality of life in general. (4) The high religious level of petients enjoy the higy Quality of life in the spiritual aspects. As a results of analysis above : 1. The most effective aspects of the hospice care to the terminally- ill patients was spiritual aspects. The next effective aspects was psychosocial area. 2. The least effective aspcets of the hospice care to the terminally- ill patients was physical aspects. Further study is needed to improve the quality of life in the physical aspects.

The study aimed at investigating the level of self-efficacy of science teachers towards student engagement. Although the general self-efficacy of teachers has been explored a lot but the efficacy of science teacher has not been explored more and student engagement is crucial towards understanding of science concepts. Therefore, the main purpose of the study was to find the self-efficacy of science teachers mainly towards three dimensions of student engagement (Behavioral, Cognitive and Emotional engagement). The study was carried with 150 secondary science teachers as Kathmandu. Secondary science teachers were found to be moderately high efficacious in all aspects of behavioral engagement of students except four aspects in which they showed moderate efficacy. Regarding the self-efficacy on cognitive engagement they were moderately efficacious in two aspects and were found to be moderately high efficacious in other all aspects. However, science teachers' self-efficacy was found to be moderately high. Teachers were found to be efficacious in making clasroom constructive, developing collaborative skill and high order thinking among the students. However in some aspects they were found less efficacious.

For many optimization problems where some of the system components are stochastic, the objective functions cannot be represented analytically. Therefore, modeling by computer simulation is one of the most effective means of studying such complex systems. Many, if not most, simulation optimization problems have multiple aspects. Historically, multiple aspects have been combined ad hoc to form a scalar objective function, usually through a linear combination (weighted sum) of the multiple attributes, or by turning objectives into constraints. The genetic algorithm (GA), however, is readily modified to deal with multiple aspects. In this paper we propose a MAGA (Multiple Aspects-based Genetic Algorithm) as an algorithm for finding the Pareto optimal set. We demonstrate its ability to find and maintain a diverse "Pareto optimal population" on two problems.

In this study, when variable-amplitude load with various applying mode acts on the pre-crack tip, we examined how fatigue cracks behave. Hence aspects of the deformation caused by changing the applying mode of single overload and propagation behavior of fatigue crack were experimentally examined: What kinds of the deformation would be formed at pre-crack and its tip\ulcorner What aspects of the residual plastic deformation field would be formed in front of a crack\ulcorner How aspects of the plastic zone could be evaluated\ulcorner As applying mode of single overloading changes, the deformation caused by tensile and shear loading variously showed in each applying mode. The different aspects of deformation make influence on propagation behavior of cracks under constant-amplitude fatigue loading after overloading with various modes. We tried to examine the relationship between aspects of deformation and fatigue behavior by comparing the observed deformation at crack and crack propagation behavior obtained from fatigue tests.

Alberta Stroke Program Early Computed Tomographic Scoring (ASPECTS) is a 10-point CT-scan score designed to quantify early ischemic changes in patients with acute ischemic stroke. However, an assessment of ASPECTS remains a challenge for neuroradiologists in stroke centers. The purpose of this study is to develop an automated ASPECTS scoring system that provides decision-making support by utilizing binary classification with three-dimensional convolutional neural network to analyze CT images. The proposed method consists of three main steps: slice filtering, contrast enhancement and image classification. The experiments show that the obtained results are very promising.

This study aims to provide direction for the brand goals approaching and analyzing previous studies in social psycholog y perspective, focusing on man and society relationship. 526 preceding 'brand space' associated papers from 1992 to 2012 were collected and analyzed them by year, by space and by theme utilizing the realism methodology, the theor etical relationship methodology. The numbers of the study for 'brand space' had increased gradually from 2003 to 2010 then climbed vertically and the most common study was about place, that shows there is a relationship between variou s social phenomena and human psychology. For the thematic analysis, 'Social psychological components of the brand' based on social psychology was used for analyzing the cognitive aspects, the relational aspects, and the attitudinal aspects. The most common study was the study of the cognitive aspects, and relational aspects, and lastly the attitud inal aspects in order. The strategy was the most common research for the brand associated study. The ultimate point of the strategy is to get 'attitude'. From social psychology perspective, there is a cycle in the minds of consumers, 'Identification', 'Internalization', 'Conformity' and 'Compliance'. Structure of these relationships can provide a clue that consumers' attitude lead the consumers' action.

This Study aims to find out the planning aspects and detailed techniques in terms of concept of the Ecological Industrial Parks. It consists of the three parts : Firstly, according to theoretical review, this study gives a definition of the concept of ecological industrial parks. Secondly, it institutes planning aspects of ecological industrial parks based on the main concept. Thirdly, 8 case studies show us analysis of detailed techniques used each planning aspects. Ecological industrial parks mean industrial systems which make energy and substance circulated in order to reduce environmental pollutions inside and outside of park like natural ecosystem. To actualize ecological industrial parks, we have to adopt 3 planning aspects which are energy and substance recycling system, environmentally-friendly site planning based on ecology concept, constructing of ecological production and management. In case study, detailed techniques from each planning aspects are shown in table 8. As a result of case study, detailed techniques about planning of energy and substance recycling system is accommodated most. On the other hand, environmentally-friendly site planning techniques based on ecological concept is used passively. And detailed techniques about constructing of ecological production and management are very various as each cases. Finally, in terms of analysis, this study shows us appliable planning when we develop domestic Ecological industrial parks.

The multi-faceted influence of price on consumers' purchasing process of apparel products: Relationships with attitudinal and behavioral variables Price has a significant relationship to clothing products not only because of its practical, emotional and symbolic attributes but also because of its wide range and frequent changes. The purpose of this study was to identify the multi-faceted influence of price on consumers' purchasing process of clothing products. Six types of price-perceptions were related to various attitudinal and behavioral variables in a clothing purchase. A questionnaire was developed and data were collected from 720 adult women living in Seoul. Factor analysis, multiple regression, t-test and canconical correlation were employed to analyze the data. Low price consciousness was negatively related to product-oriented aspects of clothing and effected the one-price sale, visiting public markets and using interpersonal sources of price information. Value for money consciousness was positively related to product-oriented aspects of clothing and consumers' age or marriage and effected price considerations at the on-purchase and post-purchase stage. Price-quality inference was related to product-oriented and market-oriented aspects of clothing while price-prestige inference was related to visual and symbolic aspects of clothing and effected normal-price purchasing. Sale proneness was related to market-oriented aspects of clothing and effected seasonal sale price purchasing and price mavenism was related to market-oriented and visual aspects of clothing and effected price considerations at the pre-purchase stage.

Background: The IMPPAC cohort (Implications of the COVID-19 pandemic on psychosocial aspects and work ability among Brazilian workers) seeks to understand the impact of the pandemic on Brazilian workers. This article describes the occupational profile, psychosocial aspects, and work ability determined during the baseline and follow-up measurements of the cohort. Methods: Workers were invited to participate through media advertisements, social networks, and emails. From June to September 2020, 1211 workers were included in the cohort. Follow-up measurements finished on October 2021 with 633 workers. Data were collected through standardized questionnaires using Google Forms. Psychosocial aspects were assessed using the COPSOQ II-Br. Work ability was assessed using the Work Ability Index (WAI). Results: At baseline and follow-up, high proportion of workers were in the risk zone with regard to work pace, emotional work demands, influence on work, work-family conflict, burnout, and stress. Approximately 75% of the workers reported good to excellent work ability at baseline and follow-up. Conclusion: The occupational profile, psychosocial aspects, and work ability of Brazilian workers from the IMPPAC cohort were described. Psychosocial aspects and WAI were similar at baseline and follow-up.
