Word-of-mouth (WoM) is defined by consumer activities that share information concerning consumption. WoM activities have long been recognized as important in corporate marketing processes and have received much attention, especially in the marketing field. Recently, according to the development of the Internet, the way in which people exchange information in online news and online communities has been expanded, and WoM is diversified in terms of word of mouth, score, rating, and liking. Social media makes online users easy access to information and online WoM is considered a key source of information. Although various studies on WoM have been preceded by this phenomenon, there is no meta-analysis study that comprehensively analyzes them. This study proposed a method to extract major researches by applying text mining techniques and to grasp the main issues of researches in order to find the trend of WoM research using scholarly big data. To this end, a total of 4389 documents were collected by the keyword 'Word-of-mouth' from 1941 to 2018 in Scopus (www.scopus.com), a citation database, and the data were refined through preprocessing such as English morphological analysis, stopwords removal, and noun extraction. To carry out this study, we adopted main path analysis (MPA) and word co-occurrence network analysis. MPA detects key researches and is used to track the development trajectory of academic field, and presents the research trend from a macro perspective. For this, we constructed a citation network based on the collected data. The node means a document and the link means a citation relation in citation network. We then detected the key-route main path by applying SPC (Search Path Count) weights. As a result, the main path composed of 30 documents extracted from a citation network. The main path was able to confirm the change of the academic area which was developing along with the change of the times reflecting the industrial change such as various industrial groups. The results of MPA revealed that WoM research was distinguished by five periods: (1) establishment of aspects and critical elements of WoM, (2) relationship analysis between WoM variables, (3) beginning of researches of online WoM, (4) relationship analysis between WoM and purchase, and (5) broadening of topics. It was found that changes within the industry was reflected in the results such as online development and social media. Very recent studies showed that the topics and approaches related WoM were being diversified to circumstantial changes. However, the results showed that even though WoM was used in diverse fields, the main stream of the researches of WoM from the start to the end, was related to marketing and figuring out the influential factors that proliferate WoM. By applying word co-occurrence network analysis, the research trend is presented from a microscopic point of view. Word co-occurrence network was constructed to analyze the relationship between keywords and social network analysis (SNA) was utilized. We divided the data into three periods to investigate the periodic changes and trends in discussion of WoM. SNA showed that Period 1 (1941~2008) consisted of clusters regarding relationship, source, and consumers. Period 2 (2009~2013) contained clusters of satisfaction, community, social networks, review, and internet. Clusters of period 3 (2014~2018) involved satisfaction, medium, review, and interview. The periodic changes of clusters showed transition from offline to online WoM. Media of WoM have become an important factor in spreading the words. This study conducted a quantitative meta-analysis based on scholarly big data regarding WoM. The main contribution of this study is that it provides a micro perspective on the research trend of WoM as well as the macro perspective. The limitation of this study is that the citation network constructed in this study is a network based on the direct citation relation of the collected documents for MPA.

A local government is not a group under central government, rather it fulfills the function independently as a economic social administrative unit. Belief and role of chief of regional government, and citizen's understanding and interest regarding importance of an election pledge are getting higher. Thus, this study researches election pledges which can be a main variable of urban plan. Especially, the study attempts to analyze impacts of election pledge on urban spatial structure and regional economic structure. When relationship between election pledge and Use Zoninig change were analyzed, the result showed that development related entire use Use Zoninig changes were related with election pledge. When it was subdivided according to each use area, relationship of use area change among election pledge and urban spatial structure found to have relatively high in resident area. In addition, relationship between population factor and election pledge was high. This can be judged as election pledge and urban spatial structure change have relationship. Particularly, sectors related with residents are expected to have high correlation. As a result, pledges regarding general welfare administrative part were a few at areas with many pledges regarding regional economic development. So, it can be classified as regional economic development oriented pledge suggesting area and welfare administrative oriented suggesting area. Through realization of these pledges, it might be able to affect urban spatial structure changes.

This study analyzed changes in postpartum depression in mothers from one month after childbirth to the first year using panel data collected overtime, in an effort to determine the relationship between the amount of change and child-rearing system variables. The subjects were 1097 mothers who belonged to both the lower and upper $30^{th}$ percentile groups in the depression change distribution of the 2008 Korean Children Panel Study (PSKC), a large, population-based study conducted by the Korea Institute of Childcare and Education. The data were analyzed by t-tests, $x^2$ tests, partial correlation coefficient analyses and regression analyses. The results are summarized as follows: First, the mothers' postpartum depression showed a significant increase during the first year as opposed to the first month after birth. Second, after controlling for socio-demographical variables of the mothers, the changes related to depression showed a positive relationship with child-rearing stress, and the child's emotional temperament, but showed a negative relationship with the mother's self-esteem, the child's birth order, and the father's participation in child-rearing activities. Third, variables having a significant effect on changes in postpartum depression were the mother's self-esteem and child-rearing stress, the child's age in months, and social support. Variables pertaining to the mother's characteristics variables had a more powerful effect than other child-rearing system variable categories. The results suggest the necessity to develop a parental education program or a mother-child health service in consideration of the variables that affect mothers, as determined in this study, in an effort to prevent postpartum depression.

This study aims to analyze causality among Wando abalone producer prices by size using a vector autoregressive model to expiscate the leading-price of Wando abalone in various price classes by size per kg. This study, using an analytical approach, applies a unit-root test for stability of data, a Granger causality test to learn about interaction among price classes by size for Wando abalone, and a vector autoregressive model to estimate the statistical impact among t-1 variables used in the model. As a result of our leading-price analysis of Wando abalone producer prices by shell size using a VAR model, first, DF, PP, and KPSS tests showed that the Wando abalone monthly price change rate by size differentiated by logarithm were stable. Second, the Granger causality relationship analysis showed that the price change rate for big size abalone weakly led the price change rate for the small and medium sizes of abalone. Third, the vector autoregressive model showed that three price change rates of t-1 period variables statistically, significantly impacted price change rates of own size and other sizes in t period. Fourth, the impulse response analysis indicated that the impulse responses of structural shocks for price change rate for big size abalone was relatively more powerful in its own size and in other sizes than shocks emanating from other sizes. Fifth, the variance decomposition analysis indicated that the price change rate for big size abalone was relatively more influential than the price change rates for medium and small size abalone.

Objectives: The objective of study was to calculate the municipal level environmental burden of disease (EBD) due to heat wave. Methods: The data used were Korea National Health Insurance 2011 claim data and 2011 death registry. Heatwave related diseases included hypertensive heart diseases, ischemic heart diseases, cerebrovascular disease, and heat related illness. According to the method that WHO proposed, the study computed population-attributable fraction with relative risk which come from previous study and proportion of exposure which the study calculated with historical meteorology data. Results: The Average of 251 municipal EBD was 2.11 per thousand persons. The value of years lost due to disability was 11 times higher than that of years of life lost. On average EBD of county and southern geographical areas tended to be higher than those of District or city areas. The relationship between municipal deprivation index (composite deprivation index) and EBD showed the positive association, which means that the worse deprived municipal is, the higher EBD takes. Conclusions: Climate change is getting one of the major risk factors of cardio-cerebrovascular disease, which is the second leading cause of death. The study results suggested the urgent policy planning and reaction of climate change adaptation.

Our natural desire to exuviate old theory and search for new ideas means conversion and reformation. Howev-er, the new idea of the present moment will soon become an ancient history when the next generation emerges with more advanced ideas. Naturally, we have learned to accept the past history and utilized it as a the foundation for the future. Through the repeated process of the learning method, the popula-tion cultivate themselves with proper understanding and appropriate attitude toward design. By analyzing social behaviors of the past and living conditions, we can ex-pand our imaginations beyond limits. Each society and its local condition have tremendous effects on the develop-ment and progress of artistic theories, techniques and craftsmanship, and potential design of every day use products. Today, interior design can not afford to ignore the or-ganic relationship of life style and space. Thus, the plan-ning of space means the planning of life style. Life style, as it is, has a vast definition and changes with time. That is why spaces, which consider the life style and its environment when designed, show different aspects ac-cording to its corresponding time. Interior design, in particular, differs by time and re-gion to create its unique style. The change in space is the natural result of the change in life style which again is sensitive to the change in cultural and environmental elements. Design is no longer designing of mere physical elements and environment. Design should be taken as the equivalent of creating spiritual culture.

There are few research on the social drinking experience reported by women. Thus, it is necessary to understand the increasing tendency of womens drinking experience in the sociocultural context. This study was aimed to explore and delineate the drinking experience of full-time house wives base don Strauss and Corbin's grounded theory (1998). The subjects of this study were 10 full-time middle-aged house wives who were living in Seoul region. The data were collected through several in-depth interviews and observations until the theoretical saturation was achieved. The data were analyzed using Strauss and Corbin's grounded theory method. The results of this study generated a paradigm that the drinking experience of the full-time middle-aged house wives has a core category of 'free-oneself-from' and is also connected with mingling, anguish, accessibility, reaction of other people, change, personal resources, self-expression and building relationships by drinking. All processes from the occurrence of the central phenomenon to extinction are as follows; 1) Starting the process of the drinking experience for mingling and resolving anguish, and by having an easy accessibility; 2) Perceiving the process of reaction by other people, physical change of herself. and psycho-behavioral change; 3) Experiencing the process of free-oneself from thorough drinking; 4) Acknowledging the process of the resources for free-oneself-from; 5) Selecting the process of self-expression according to the resources; 6) Building the process of the relationship with drinking as a way of self-expression. Based on this paradigm, 4 hypothesis and 4 types are generated. Thus, this study suggests that it is useful to develop nursing interventions to improve the self-esteem of the full-time middle-aged house wives and to provide them various methods of problem solving strategies. This study also proposes that there should be a strategic program for the women so that they could make a route for positive self-expression by achieving a proper relationship with drinking.

This study aimed to look for the possibility of dissolving social exclusion about the social vulnerable classes through the culture welfare programs. For this purpose, we analyzed interview records focused on the culture welfare practitioners applying the Modified Grounded Theory Approach worked out by Kinosita. The results showed that the culture welfare programs functionated of dissolving social exclusion about the social weaks by enhancing latent faculties and the sense of self-respect of them through providing various opportunities of culture fruition. It was appeared that the culture welfare programs promoted creative competence and the sense of self-respect, and strengthened the sense of solidarity of the participants by using the approaching strategies of offering various opportunities of creational experience, atypical operating programs centered on the process, establishing of the participants' subjecthood, and communal activities. That is, it was proved that actually the social weaks experienced the change of life with feeling emotional satisfaction, promoting family and human relationship, establishing positive identity, empowerment, participating communal activities, and so on, through the culture welfare programs. From these results we can know that if we provide the programs mixing the culture welfare programs with social welfare services which traditionally reinforced social exclusion about the social vulnerable classes by stigma, the social exclusion about them can be dissolved.
