Purposes: The purpose of this study is to examine the effects of health service quality and perceived risks of Korean hospitals on the satisfaction and revisit of Kazakhstan's customers. Among two classified groups: health service providers and health service receivers, this study aims to identify the effects of health service receivers in Kazakhstan's health service quality and perceived risks on customer satisfaction. Methodology: Hypotheses were developed upon the explanations on health service quality, perceived risks, customer satisfaction, and revisit, advanced by prior literature. A survey was conducted on the effects of health service receivers in Kazakhstan's health service quality and perceived risks on customer satisfaction and revisit. The proposed hypotheses were confirmed by examining validity and reliability of the collected data, followed by regression analysis. Findings: First, the five dimensions: reliability, responsiveness, assurance, empathy, and tangibles showed a positive correlation between the impacts of health service quality and customer satisfaction of Korean hospitals. Second, the physical risk, social risk, time-loss risk showed a negative correlation. Lastly, the relation between customer satisfaction and revisit showed a positive correlation. Practical Implication: Health service quality and perceived risks were identified to impose significant effects on Kazakhstan customers. The identified results suggest that Korean hospitals should implement management strategies based on the customers' satisfaction factor.

The purpose of this study is to econometrically analyze the negative impact of the May 18 Democratic Uprising on the Gwangju/Jeonnam regionional economy using the Synthetic Control Method (SCM). The SCM SCM is a methodology similar to the difference-in-difference(DID) method of microeconometrics. It is applied to macroeconomic variables such as country, region, etc. to estimate the causal relationship between specific events and the dependent variable. In this study, as of 1980, local tax revenue data of metropolitan local governments were used as a proxy variable for the economy of the region, and the impact of the May 18 Democratic Uprising on the economy of Gwangju/Jeonnam region was analyzed through various socio-economic indicators. In this study, data were used to analyze from 1971 to 2000, and as a result of empirical analysis, local tax revenues in Gwangju/Jeonnam area were less collected than normal routes up to 17%. In addition, the significance of this analysis was confirmed through in-time placebo effect analysis and in-space placebo effect analysis, which are methods of analyzing the robustness of the control group synthesis method.

In this paper, we aim to build a gentrification analysis model and examine its characteristics, focusing on the point at which rents rose sharply alongside the recovery of commercial districts after the gradual resumption of daily life. Recently, in Korea, the influence of social distancing measures after the pandemic has led to the formation of small-scale commercial districts, known as 'hot places', rather than large-scale ones. These hot places have gained popularity by leveraging various media and social networking services to attract customers effectively. As a result, with an increase in the floating population, commercial districts have become active, leading to a rapid surge in rents. However, for small business owners, coping with the sudden rise in rent even with increased sales can lead to gentrification, where they might be forced to leave the area. Therefore, in this study, we seek to analyze the periods before and after by identifying points where rents rise sharply as commercial districts experience revitalization. Firstly, we collect text data to explore topics related to gentrification, utilizing LDA topic modeling. Based on this, we gather data at the commercial district level and build a gentrification analysis model to examine its characteristics. We hope that the analysis of gentrification through this model during a time when commercial districts are being revitalized after facing challenges due to the pandemic can contribute to policies supporting small businesses.

This paper is performed to examine the effect of creep during the primary consolidation and the applicability of the Yin's EVP (Elasto-Visco-Plastic) model. In ordinary consolidation theories using the elastic model, the primary consolidation process can be expressed but the secondary consolidation process cannot. It is due to the viscosity, which can express the secondary consolidation, and is sometimes related to the scale effect (difference of the thickness of clay layer between laboratory sample and field condition) such as hypotheses Type A and Type B shown by Ladd et al. (1977). Usually, the existence of the creep during the primary consolidation has been conformed and the Type B is well acceped. On the other hand, from the large-scaled consolidation tests the intermediate characteristic between Type A and Type B was proposed as Type C by Aboshi (1973). In this study, to clarify the effect of creep on the settlement-time relation during the primary consolidation in detail, Type B consolidation tests were performed using the separate-type consolidation test apparatus for a peat and clay. Then the test results were analyzed by using Yin's EVP Model (Yin and Graham, 1994). In conclusion, followings were obtained. At the end of primary consolidation, the compression for the subspecimens should not be the same because of the difference of the excess pore water pressure dissipation rate. And the average settlement measured by the separate-type consolidometer coincides with the analyzed one using the Yin's EVP model. As for the dissipation of the excess pore water pressure, however, the measured excess pore water pressure dissipates faster compared with the Yin's model.

자연재해 중 홍수의 경우 단기간에 발생하며, 큰 인명 및 금전적 피해를 가져오는 재해이다. 1970년~2017년 국내 홍수 피해 분석결과 사상자(총 8,152명)는 점차 줄어드는 추세를 보이지만, 반대로 피해액(총 17조5,000억원)은 증가하는 것으로 나타났다(wamis, 국가수자원관리종합정보시스템). 이러한 국내 홍수 피해를 최소화하기 위해서는 각 유역 또는 지역별 특성을 고려한 홍수 취약성 평가가 필요하다. 홍수 취약성은 대상 지역의 기상, 지형, 인문학적 상황에 따라 상이하게 나타나며, 홍수 취약성을 평가하는 인자의 선정 또한 매우 중요하다. 따라서 본 연구에서는 홍수 피해 자료와 홍수 인자간의 인과관계를 분석하여 홍수 취약성 지표 선정 및 취약성 평가를 실시하였다. 홍수 취약성 평가를 위해 홍수 피해 자료와 대상 인자간의 상관성 분석을 통해 상관계수 값이 상대적으로 높게 나온 인자를 선정하였다. 대상 인자는 크게 기상학적 인자, 지형학적 인자, 사회·인문학적 인자로 구분하였다 선정된 인자 간 서로 높은 상관성을 보일 시 공선성이 존재함을 의미하며, 이러한 공선성을 방지하기 위해 VIF (Variance Inflation Factor, 분산팽창계수)를 통한 공선성 검토를 적용하였다. 또한 각 인자 간 에는 서로 다른 단위 및 범위를 가진다. 이러한 경우 특정 인자들의 증감을 취약성 평가에 반영하기에 어려움이 있으며, 유역별 평가 시 신뢰성이 낮아진다. 따라서 Re-scaling 방법을 통해 각 인자의 단위 및 범위를 표준화 후 동일가중치 법을 적용하였다. 본 연구에서는 전체 유역 중 홍수피해가 가장 크게 발생하는 낙동강 태화강 유역을 연구 대상 지역으로 선정하였다. 태화강은 도심지의 중심부를 흐르는 하천이며, 산지의 고도가 높은 지형적 특성을 가지고 있어 홍수에 대한 취약성이 높은 것으로 나타났다(wamis, 국가수자원관리종합정보시스템). 태화강 유역 홍수 취약성 평가결과 유역별 기상, 지형, 인문학적 특성에 따라 홍수 취약성이 높게 나타나는 결과를 보였다. 이와 같은 결과는 유역 내 도심지 비율, 인구밀도, 토지피복 특성에 의한 것으로 주로 지형학적 인자로 인해 취약성이 높게 나타났다. 본 연구에서 활용한 홍수 취약성 평가 방법은 향후 홍수피해 대책 수립에 사용될 수 있을 것으로 판단된다.

The purpose of this study is to provide basic data in order to improve service quality based on empirical analyses about a relationship among positive psychological capitals, service quality, and job satisfaction of professional care workers under the Long-Term Care Insurance in South Korea. In this study, total 430 numbers of the workers who were currently working in nursing homes for the elderly at the cities of Ansan, Anyang, Bucheon, and Kwangmyeong in Gyeonggi Province, South Korea, participated in self-report questionnaires. Only 393 questionnaires were used for the final analyses after excluding the ones that neither were not returned nor didn't completed it all. These are major results. First, positive psychological capitals affect positively on service quality. Second, job satisfaction works as a mediating effect in the process of positive psychological capitals affect on service quality. Based on above results, it is possible to suggest it as down below. First, it is required to have policies that will be helpful for both positive psychological capitals and capacity building through human resource management in systematic approaches. Second, it is also required to acknowledge that having positive psychological capitals is effective to improve both their job satisfaction and service quality. Therefore, it is necessary to change environmental circumstances in relevant institutions where this acknowledgement will be applied.

The purpose of this paper is to investigate the association between residential environment satisfaction and elderly depression with a focus on the mediating effect of physical activity. The survey of Living Conditions and Welfare Needs of Korean Older Persons performed in 2017 was used for analysis. Among total 10,299 who aged 65 years or above and participated in survey, only 10,059 people who answered the survey questions by themselves without missing main questions were included in this analysis. Mediation effects were tested with Baron & Kenny(1986) method and Sobel test(Sobel, 1982). As results, first, residential environment satisfaction was negatively associated with elderly depression. Second, residential environment satisfaction was positively related to physical activity. Lastly, it was found that physical activity mediated the relationship between residential environment satisfaction and elderly depression. The results showed that older adults who satisfied in residential environment were more likely to participate in physical activity, and older people who participated in physical activity were less likely to experience depressive symptoms. Based on these results, the paper suggests the importance of subjective satisfaction of residential environment and participation of physical activity for mental health in later life, and some intervention strategies for Aging In Place.

This study aims to propose implications for the development of archival content of archives management institutions in Korea by analyzing cases of the archival content on Instagram of the national archives in the Anglosphere. The basic information of the research target's Instagram account, including the creation date, content, and the number of followers, was investigated, and the posts' contents and interaction types with high user responses were analyzed. As a result, to spread the records information service using Instagram, producing images and short-form content that can be intuitively checked through mobile screens and creating content that will attract the attention of primary users are required. Moreover, it is necessary to develop content for informative communications that can be shared with other users. There is also a need to enhance the exposure and searchability of the institution's Instagram account by strengthening connections with the institution's existing online resources and enabling communications, such as using hashtags, following related institutional accounts, and providing feedback on the contents' comments with followers. This study is meaningful in that it examined cases of archival content for Instagram and suggested their applications, and it can be used as basic data to help plan archival contents to spread the archival culture.

As the influence of online reviews on consumer decision-making increases, concerns about review manipulation are also increasing. Fake reviews or review manipulations are emerging as an important problem by posting untrue reviews in order to increase sales volume, causing the consumer's reverse choice, and acting at a high cost to the society as a whole. Most of the related prior studies have focused on predicting review manipulation through data mining methods, and research from a consumer perspective is insufficient. However, since the possibility of manipulation of reviews perceived by consumers can affect the usefulness of reviews, it can provide important implications for online word-of-mouth management regardless of whether it is false or not. Therefore, in this study, we analyzed whether there is a difference between the review evaluated by the consumer as being manipulated and the general review, and verified whether the manipulated review negatively affects the review usefulness. For empirical analysis, 34,711 online book reviews on the LibraryThing website were analyzed using multilevel logistic regression analysis and Poisson regression analysis. As a result of the analysis, it was found that there were differences in product level, reviewer level, and review level factors between reviews that consumers perceived as being manipulated and reviews that were not. In addition, manipulated reviews have been shown to negatively affect review usefulness.
