This paper argues that Christian education for sustainability should be a spiritual education that fosters the spirituality of contentment, poverty, sharing, and justice through a critical review of the concept of "Sustainable Development" (SD), which emerged to overcome today's climate and ecological crisis. To this end, first of all, the efforts and limitations of international cooperation to overcome the deepening environmental problems will be considered. That is, economic interests have been prior to the environmental issues. When it comes to the 'Green Revolution,' there has been a huge gap between the ideal and the reality, so a sustainable society has become distant. Faced with this situation, Christian theology has been trying to build a new theological paradigm, breaking away from the limits of anthropocentric and afterlife-centered theology based on the dichotomy between the physical and the spiritual. Through such theological reflections, Christian education needs to carry out spiritual education focusing on how to deal with the problem of human greed for the restoration of the created world. In this regard, this paper presents the spirituality of contentment, poverty, sharing, and justice. For developing it, this article suggests deep theological reflection and repentance on human greed, listening to the victim's voice, moderation in consumption, investigation of alternative cases, and decisive action to reveal the truth from the victim's point of view.

The purpose of this study present directions and a model of Christian ecological spirituality education in the post-corona era, and to expand Christian education beyond the private to the public. There are various problems in today's modern society. The 4th Industrial Revolution and COVID-19 has changed daily life and standards over the past few years As a result, the post-corona discourse is becoming more active. In this context, this study conducted a study on what educational alternatives should be prepared in terms of Christian education for the post-corona era. Especially, one of the urgent problems that modern society needs to solve today is the problem of the ecological environment, and I tried to prepare an alternative in perspective of Christian spiritual education. To this end, the causes of today's ecological environmental problems were examined in three perspectives: global, social, and personal. It could be summarized as the problems of neoliberal globalization, anthropocentrism, and ecological ignorance, respectively. To solve this, the direction of Christian ecological spirituality education was presented as the spirituality of participatory responsibility, the spirituality of ecocentrism, and the spirituality of ecological conversion. The specific model of Christian ecological spirituality education was established by presenting educational purposes and goals, educational methods and contents, educational environment and evaluation.

An analytical method for the determination of thyroid hormones in plasma samples has been studied by solid-phase extraction and high-performance liquid chromatography/diode array detector (DAD)/electrospray ionization (ESI)-mass spectrometer. Seven thyroid hormones were successfully separated by gradient elution on the reverse phase Hypersil ODS column (4.6 mm I.D., 250 mm length, particle size $5{\mu}m$) with ammonium formate buffer and acetonitrile. In addition, these compounds were confirmed by UV spectra and ESI-mass Spectra. The extraction recoveries of thyroid hormones in the plasma sample (at pH 3) were in the range of 74.5-115.7 % with solid-phase extraction by C18, followed by elution with 4 mL of methanol. The calibration curves showed good linearity with the correlation coefficients ($r^2$) varying from 0.9939 to 0.9978 and the detection limits of all analytes were obtained in the range of 20-50 ng/mL (38.1-162.8 pmol/mL). As a result, thyroxine was found in the range of 50.98-112.97 ng/mL in normal plasma samples.

A 2(pedagogical agent: with vs. without) × 2(on-screen text: with vs. without) between-subject design was used in this study to investigate the effects of pedagogical agent and redundant on-screen text on video learning. In the case of the educational video without redundant on-screen text, there was no difference in social presence, satisfaction, and intention to continue learning regardless of the presence of a pedagogical agent. However, when the educational video contained redundant on-screen text, participants who watched educational video with pedagogical agent perceived higher social presence, satisfaction and intention to continue. In terms of academic achievement, no difference was found whether redundant on-screen text was contained or not. It supports some of the previous studies on the reverse-redundancy effects, suggesting that the inclusion of redundant text does not necessarily cause the reduction of learning outcomes. Video learning shows a higher dropout rate than face-to-face learning. Therefore, it is particularly important to understand how to strengthen interactions with learners and motivate them to keep themselves engaged in learning. This study discussed whether pedagogical agent and on-screen text are factors that induce continuous participation of learners in video learning.

The purpose of this study was to identify the differences of cognitive responses, emotional responses, customer satisfaction, and service loyalty about service encounter quality by types of restaurants and to analyse emotional responses, customer satisfaction, and service loyalty in accordance with level of service encounter quality. The questionnaire were collected from customers (N=812) who had used restaurants in Seoul, aiming at 15 or more-year-old customers from October 24, 2005 to November 6, 2005. The main results of this study were as follows: Statistically significant difference was showed in importance and performance of interaction quality, importance and performance of physical environment quality, performance of outcome quality depending on types of restaurants, while significant difference was not indicated in importance of outcome quality by types of restaurants. Positive emotional response was significantly high by types of restaurants in order of fine-dining restaurants, family restaurants, and fast-food restaurants, while negative emotional responses were significantly higher in fast-food restaurants than in the other two types. As far as Customer satisfaction are concerned, fine-dining restaurants showed higher customer satisfaction than the other two types. Attitudinal service loyalty was high in fine-dining restaurants, family restaurants and fast-food restaurants in order and behavioral loyalty was not significantly different with each type of restaurant. In accordance with level of service encounter quality, cluster analysis was conducted and the clusters were divided into 'high-valuation' and 'low-valuation'. 'High-valuation cluster' and 'low-valuation cluster' showed significant difference depending on types of restaurants that customers used(p<.001). The customers who used fine-dining restaurants and family restaurants valued the performance of service encounter highly. However, in fast-food restaurants, a lot of low-valuation customers existed. Therefore, fast-food restaurants have to improve performance of interaction quality, outcome quality and physical environment quality in service encounter. In addition, in 'high-valuation cluster' who valued service encounter quality highly showed higher scores in positive responses, customer satisfaction, service loyalty than in 'low-valuation cluster', and showed low negative responses.

This study examined the effects of the economic activity status on the mental health of middle and older adults. In terms of mental health, a theoretical model was used to evaluate the mediating role of the income level and the satisfaction in family relationship. Using data from Korean Longitudinal Study of Ageing, job seekers and those who had never worked before were excluded and employees and retirees (over 45 years old) who have both a spouse and children were selected for the analysis. The variables were the economic activity status, the income level, the satisfaction in family relationship, and the mental health. The results show that the number of employed middle and older adults were higher than that of retirees, and the satisfaction in family relationship were generally high. In terms of mental health, the level of happiness was high, while the level of depression was low. Also, the pathway analysis of the effect of the economic activity status on the mental health shows that the economic activity status directly affects the mental health and gives indirect effects through the medium of the income level and the satisfaction in family relationship.

This study aims to identify the multiple trajectories of depressive symptoms and the characteristics of each trajectory group among the elderly. This study uses five waves of longitudinal data from the Korean Welfare Panel Study (KWPS, 2006-2010). Subjects were older adults aged 60 and over who had completed at least three waves between 2006 and 2010. A total of 4,181 respondents were analyzed. The latent growth mixture model and the multiple logistic regression model were mainly used for data analysis. The major findings were as follows: After controlling for the variables of gender, age, education, marital status, self-assessed health, and poverty, this study identified four different trajectory classes: stable low depressive symptoms (71.8%), high but decreased depressive symptoms (10.6%), moderate but increased depressive symptoms (7.9%), and an increased, then a decreased pattern of depressive symptoms (9.7%). The characteristics of theses trajectories as compared to previous studies were a lower percentage of 'stable low depressive symptoms', no 'persistently high depressive symptoms', and higher level of depressive symptoms. Also, the elderly in the stable low trajectory group had better health status, higher self-esteem and a good relationship with family members, having longer working periods, and more living in non-poverty. In addition, chronic health problems, loss of spouse, and household income differentiated the increased and then decreased pattern from the low stable pattern. Also, age and public pension differentiated the moderated but increased pattern from the low stable pattern. Based on the findings of this study, the researchers suggested political and practical implications for reducing depressive symptoms in later life.

If frail elderly could use home care services adequately, quality of their life might improve and their costs of service would be decreased. The purpose of this study is to examine the factors on institutionalization of elderly using home care services in Korean long-term care insurance system. This study used the data of '2009 satisfaction survey of Korean long-term care system'. The survey proceeded using sampling data by region, level of long-term care need, and insurance type among beneficiaries from August 2009 to September 2010. The onset dates of institutionalization of 1,230 participants were ascertained from long-term care insurance claim data. This study calculated hazard ratio through Cox Proportional Hazard Model. The results showed that if elderly using home care services suffer a fracture, the hazard ratio of institutionalization is higher significantly. Although not significant, if older persons have more items of damaged cognitive functions, the hazard ratio of institutionalization is higher. The results have policy implications to supplement of home care service system and postpone institutionalization of elderly.

The purpose of this study was designed to develop an questionnaire for healthy aging. The subjects of this study were total 335 people who participated in regular exercise and went to welfare centers in Seoul. The validity and reliability were tested for verifying the developed questionnaire for healthy aging. The data were collected between June 12, 2006 and October 27, 2006. The mean, standard deviation, kurtosis, skewness, reliability, exploratory factor analysis and confirmatory factor were analyzed for statistical purpose using by SPSS-Win 12.0 program. The results were as follows; First, to obtain content validity, the results of previous research and the value system responses were submitted to a judgement group. Second, the results of the factor analysis of the 20 items making up the questionnaire were classified into the following 3 factors; physiological health(6 items), cognitive-mental health(6 items), social-support health(8 items). Third, the reliability of the questionnaire for healthy aging was 0.891(Cronbach's alpha). In the factor analysis Cronbach's alpha correlations for the 4 factors ranged from 0.642 to 0.885. Fourth, the results of confirmatory factor analysis, all the index values(NFI, RFI, CFI, Delta 2 IFI) were close to 1. Thus, this questionnaire demonstrated good reliability and validity and therefore it was an appropriate measurement of healthy aging.

In this study, we investigated the effects of ego integrity on QoL(Quality of Life) of elderly living alone, where we focused on moderating role of SF36 health factors. To investigate the cause and effect of factors, we purposively collected 282 samples from senior welfare centers in Jeonju city and exploited reliability analysis, confirmatory factor analysis and SEM(Structural Equation Modeling) for 265 cases excluding some cases with missing values. As the results, first, we confirmed ego integrity was positive predictor of QoL. Second, it was proven that the effect of ego integrity on QoL of elderly living alone was stronger in the lower physical functioning group than higher physical functioning group. Third, we also verified that the group with more difficulties in activities or work as a result of poor physical health showed higher effect of ego integrity on QoL. Based on the results, we could explain the reason of conflicts regarding how elderly's health influenced on ego integrity. Also, in the practice of intervention to elderly's problem, we found the health factors could be an indicator of direction or effect of the intervention
