The purpose of this study is to analyse the mediating effects of spirituality on the relationship between functional capacity and depression among the elderly. The conceptual framework was based on the integrated theory by Brief et al.(1993) to life satisfaction. The sample was collected through convenience sampling of 413 elderly persons who were 65 years of age or older drawn from senior welfare centers, community senior centers, and religious institutions in Seoul, Incheon, and Gyeonggi Province. Data analysis was performed using Structural Equation Modeling(SEM). The main findings of the present study are as following: First, spirituality had the mediated effects on which depression and IADL influenced life satisfaction. Particularly, existential spirituality on life satisfaction had larger effect size than religious spirituality. Second, the results showed that religious spirituality had positive effects on existential spirituality. These findings demonstrate that the development and implementation of programs geared for fostering religious spirituality and existential spirituality of senior citizens are needed to improve life satisfaction in the field of social welfare. To this end, the foundation of spiritual practice in the field of social work with older people should be constructed through a spirituality-related system and professional training.

This study was undertaken to validate and assess the reliability of the Korean version of professional quality of life scale (K-ProQOL) that measures the compassion satisfaction, compassion fatigue and burnout among clinical nurses in Korea. We conducted an internal consistency reliability and construct validity by applying confirmatory factor analysis using SPSS WIN (24.0) and AMOS (18.0). Survey data were collected from 210 nurses working at three tertiary hospitals located in Seoul. Reliable internal consistency was achieved for the K-ProQOL, with a Cronbach's alpha for the total scale and three sub scale values of 0.72-0.90. Factor loadings on three subscales of the 30 items considered ranged from 0.25 to 0.82. The model was validated by confirmatory factor analysis (RMSEA 0.05-0.1, GFI >0.7, CFI >0.7). The findings of this study demonstrate that the K-ProQOL has satisfactory construct validity and reliability to measure compassion satisfaction, compassion fatigue and burnout among clinical nurses in Korea. This is the first study assessing the validity and reliability of the Korean version of professional quality of life scale for clinical nurses in Korea.

The purpose of this study is to identify the main factors helping university students sucessfully adapt to campus life and achieve academic accomplishment through a critical period in personal development. For this purpose, the analysis verifying influence of self leadership as an individual trait variable and social support as a socio environmental trait variable on academic achievement of university students and the mediating effect of school adjustment among them was conducted. Total 271 responses collected by implementing a questionnaire survey in "S", a four-year private university located in Seoul, were used for the analysis. The validity of the measurement was verified through confirmatory factor analysis and the relationship among the variables was examined through structural model equation, bootstrap and sobel test. The major finding of this study are as follows. First, this study confirmed the causal relationship of self leadership and social support impacting on academic achievement of university students. This result suggests that an integrated approach taking into account both individual and socio environmental factors is necessary to support academic achievement of university students. Second, it was proved that self leadership and social support indirectly influences academic achievement through school adjustment. This demonstrates that school adjustment is an important predictor of academic achievement as well as plays a major role in mediating among self leadership, social support and academic achievement. In conclusion, the results of this study conveys its significance in suggesting the necessity to provide insititutional support on individual trait and socio environmental factor enabling university students sucessfully to adapt to campus life and achieve academic achievement.

This study was designed to analyze vegetation units using a phytosociological method and to identify the ecological characteristics of each vegetation unit, for forest vegetation from Misiryeong to Danmokryeong of Baekdudaegan, in which, in total, 150 plots were surveyed during May to October 2016. Using community classification according to phytosociology, the Quercus mongolica community group was classified at the top level of a vegetation hierarchy that was classified into an Abies koreana community and a Carpinus cordata community. The A. koreana community was divided into Thuja koraiensis and A. koreana typical groups. The T. koraiensis group was subdivided into Pinus pumila and Betula chinensis subgroups. The C. cordata community was divided into Sasa borealis and C. cordata typical groups. Thus, this forest vegetation comprised one community group, two communities, four groups, and two subgroups and indicated five vegetation units. After analyzing the correlations among the five vegetation units classified by this plant sociological method and the environmental factors like altitude, bare rock, number of present species, and coverage of tree layer with a coincidence method, the A. koreana community and C. cordata typical group were found to be distributed above 1,000 m in altitude, and the S. borealis group was distributed below 1,000 m in altitude. Except for vegetation unit 1, vegetation units tended to be mainly distributed where there was less than 20% bare rock. There was no typical tendency in the number of species present; vegetation unit 5 showed the most abundance among the vegetation units. Coverage by the tree layer mostly exceeded 60%, except for vegetation unit 1.

This study investigated the impact of cellulase treatment on the extraction yield of potato starch (PS), and compared the physicochemical properties of PS by conventional (CSE) and enzymatic (ESE) starch extraction. In ESE, the PS extraction yield was predominantly influenced by reaction temperature, time and their interaction, compared to the cellulase concentration. When potatoes were treated for 8 h at $40^{\circ}C$ with 1.5% cellulase, the PS extraction yield was about 3.4-fold higher than that by CSE. Compared to CSE-PS, ESE-PS showed lower total starch contents and higher amylose contents, resulting in lower swelling factors and distorted pasting viscosity profiles accompanied by absence of peak and breakdown viscosities. However, ESE did not affect the gelatinization characteristics of PS. Overall results suggested that ESE can provide the highest yield of PS, and ESE-PS can be a potential starch source for extending the utilization of PS in food industries.

Today, in the cultural properties research, there are several methods for knowing the culture of the past through a lot of information that remains and relics contain. Especially, statistical method like presumption of producing center were introduced from computer development at the early 20th century. This study showed the characteristic about firing historic sites presumed as a tile-kiln in the remains of Cheonwang temple sites, Hanam, Gyeonggi province. Also, I used nature scientific methods for correlation between tiles excavated at historic sites and circumference building and obtained there results as follows. First, soft tile parts showed similar water suction ratio(over 10%) like another tiles, except hard tile parts. Second, identification about mineral crystallization in a sample showing low water suction ratio confirmed a result that Mullite, Tridymite, Cristobalite as high temperature crystal form were presented. I know that firing temperature was higher than the other tile parts from this result. Third, statistical analysis from micro-component resulted that tiles excavated at firing historic sites and Cheonwang temple sites were closely connected. As the results, I knew that the tiles got a supply after the establishment of tile-kiln, not at a long distance at the period of Cheonwang temple construction.

The Seoul's 2030 Youth-Housing has been regarded as the only option to procure rental housing sites in downtown Seoul. But its supply did not catch up with the initial expectation, and the criticism that it may disrupt the current zoning system of the city has persisted. Consequently, the 2030 Youth-Housing policy has undergone amendments for six times within the last three years, and the significant changes in its guideline also have been made within the last one year. The study, in this context, tries to figure out the tendencies of those changes made in the guidelines so far by analyzing the aspects of the parcels allowable for Youth-Housing as well as the areas allowable for up-zoning. In the process, the propositional logic is to be adopted to draw the scope of the buildable areas for Youth-Housing. For this, the study refines the raw GIS data, inputs the values for each proposition, and proceeds the logical operation to judge every parcel of the city to discern whether it is eligible for a buildable site and/or for up-zoning for Youth-Housing. It is seen that: 1) the buildable sites rather evenly distribute around the peripheral subway-station areas while more concentrating on the quasi-residential and commercial areas; and 2) the areas eligible for up-zoning have the tendency to concentrate more on quasi-residential areas than others.

In the recent years, Gov.2.0, which strengthens not only a claim for freedom of information but also sharing public information, became a new paradigm of government operations. In line with the paradigm the Korean government promotes the Gov.3.0 policy. This study exams the freedom of information system, which expends its roles and responsibilities for enhancing the usage of public information in the Gov.3.0 era. Furthermore, it analyzes the system's usability from the perspective of users. The freedom of information system is the fundamental portal for all the public information's disclosure and usage. Without providing the solution for problems of the system, the Korean government's Gov3.0 policy cannot succeed. Also, Park Geun-hye Government's Gov.3.0 initiatives which consists of tasks, such as reinforcing freedom of information, immediate releasing original documents, and expending public access to information, should be done through the freedom of information system. The importance of the system is increasingly heavy. It is not only the simple online contact point for public information, but also a public sphere for sharing public raw data and for implementing the Gov.3.0 vision. However, the current system still does not slove it problems. This study analyzes the system's problems in terms of usability and sustainability. As a result, it provides three alternative strategies for the freedom of information system, including 'personnel and financial support expansion', 'strengthening user-friendly operating' and 'establishing long-term strategies for system improvement.

This paper has made an empirical research on airline staff working at Incheon international airport, who perceived safety culture in their organization and delivered safety information while the staff were providing service against passengers. The purpose of this paper was to analyze the relationship among safety culture, service quality and service provider efficacy to find out which factor of safety culture had a significant effect on both service quality and service provider efficacy. Following the results from empirical research, this paper would provide administrative implications which could be applied to improve airline's service quality and to manage effectively the airline staff at field. According to research, it was found fairness culture among safety cultures had a positive and significant effect on both service quality and service provider efficacy. However, reporting/studying culture had a negative effect on them. In other words, it would decrease airline service quality and prevent active service provider's efficacy at airport if a airline management focused reporting/studying culture of safety. It is important to settle down fairness culture of safety to motivate and improve service quality.

What is unknown about Leibniz (Gottfried Wilhelm Leibniz, 1646~1716), a great philosopher and mathematician, is that he inquired about ginseng. Why Leibniz, one of the leading figures of the Enlightenment, became interested in ginseng? This paper excavates Leibniz's references on ginseng in his vast amount of correspondences and traces the path of his personal life and cultural context where the question about ginseng arose. From the sixteenth century, Europe saw a notable growth of medical botany, due to the rediscovery of such Greek-texts as Materia Medica and the introduction of a variety of new plants from the New World. In the same context, ginseng, the renowned panacea of the Old World began to appear in a number of European travelogues. As an important part of mercantilistic projects, major scientific academies in Europe embarked on the researches of valuable foreign plants including ginseng. Leibniz visited such scientific academies as the Royal Society in London and $Acad{\acute{e}}mie$ royale des sciences in Paris, and envisioned to establish such scientific society in Germany. When Leibniz visited Rome, he began to form a close relationship with Jesuit missionaries. That opportunity amplified his intellectual curiosity about China and China's famous medicine, ginseng. He inquired about the properties of ginseng to Grimaldi and Bouvet who were the main figures in Jesuit China mission. This article demonstrates ginseng, the unnoticed subject in the Enlightenment, could be an important clue that interweaves the academic landscape, the interactions among the intellectuals, and the mercantilistic expansion of Europe in the late 17th century.
