  • The purpose of this research was to evaluate the possibility of sustainable development of online advertisements conducted by fashion companies. Factors composed of sustainable development indexes of online advertisement that had been developed in previous studies were identified, and then the relevance between purchase intention and advertisement experience was evaluated. An online survey of 573 persons in the 20 to 40 age range who own mobile phone and have experienced online advertisements of a fashion brand or a fashion company was conducted. The data collected from the survey and the results are as follows. First, the validity and reliability from confirmatory factor analysis of six factors (namely, personal information protection, web use infringement, advertisement expression harmfulness, advertisement expression objectivity, emotional responsibility, and environment-friendly) and 21 questions was confirmed. Second, it confirmed that consumers gave low points to the evaluation of sustainable development indexes of online advertisement of fashion companies. In particular, that consumers gave low points with regard to both environmental friendliness and web use infringement. Third, it was identified that personal indexes such as personal information protection, web use infringement, and indexes relating to advertisement expressions do not directly influence the consumer's purchase intention. However, social indexes like emotional responsibility and environmental friendliness do have an influence on the consumer's positive action intention.

  • In this research, ANN modeling method of SMES unit is developed for stability analysis, and the optimal site is selected to maximize stabilization effect of SMES unit. The ANN is trained by learning data which is obtained through the application of complex test function into the traditional mathematical mode. In order to verify the validity of proposed modeling method, fault data of sample power system is applied to both the traditional and the ANN models. When the response of traditional and proposed models are compared, the average error for the active and reactive power are 2.51[%], and 0.24[%], respectively. From the comparison, the relevance of proposed method is validated. For the transient stability analysis, an application method of the proposed model is presented, and the transient stability performance index, which describes system stabilization effect of SMES at disturbance, is also suggested, and optimal site selection method of SMES is presented. In the viewpoint of the voltage stability, system stabilization criterion of local bus is presented from P­V curve, and then optimal site which can maximize the voltage stabilization of the whole power system, is decided from the proposed voltage stability performance index.

  • Peatland is distributed in China widely, and organic matters in soil frequently induce problems in the construction and maintenance of highway engineering due to the high permeability and compressibility. In this paper, a selected site of Dali-Lijiang expressway was surveyed in China. A numerical model was built to predict the settlement of the foundation of the selected section employing the soft soil creep (SSC) model in PLAXIS 8.2. The model was subsequently verified by the result of field observance. Consequently, the parameters of 17 types of soils from different regions in China with organic contents varying from 1.1-74.9% were assigned to the numerical model to study the settlement characteristics. The calculated results showed that the duration of primary consolidation and proportion of primary settlement in the total settlement decreased with increasing organic content. Two empirical equations, for total consolidation settlement and secondary settlement, were proposed using multiple linear regression based on the calculated results from the numerical models. The analysis results of the significances of certain soil parameters demonstrated that the natural compression index, secondary compression index, cohesion and friction angle have significant linear relevance with both the total settlement and secondary settlement, while the initial coefficient of permeability exerts significant influence on the secondary settlement only.

Relevance between Geriatric Oral health Assessment (GOHAI) and Falls : Using KLoSA 2018 7th Data (노인구강건강평가지수(GOHAI)와 낙상 경험의 관련성: 고령화연구패널조사(KLoSA) 2018년도 제7차 자료를 이용하여)

  • Purpose: This study is based on the results of previous studies that falls, which is a frequent social problem, causes physical, mental and social health problems in the elderly. In order to identify risk factors for falls in the elderly, this study derives a relationship with oral health and proposes the necessity of oral health care as part of countermeasures to prevent falls in the elderly. Methodology: The final 6,936 people were analysed using the 2018 Korean Longitudinal Study of Ageing(KLoSA) survey data, and the analysis was conducted using the multiple logistic and multiple regression analysis to investigate the relationship between Geriatric Oral Health Assessment Index (GOHAI) and falls experience. Findings: As a result of the analysis in this study, the number of falls experiences and whether or not falls were higher in the elderly female group than in the male group. The likelihood of falls experience has been statistically reduced as Geriatric Oral Health Assessment Index increases by one unit.(OR : 0.991) The number of falls has also been statistically reduced as Geriatric Oral Health Assessment Index increase by one unit.(B : -0.001) Practical Implications: The results of this study, which showed that higher Geriatric Oral Health Assessment Index was lower risk of falls, explained by the connection that oral health may affect nutritional intake, which leads to sarcopenia and physical loss, which in turn increases the risk of falls. As a way to solve the fall problem, efforts should be made to improve the oral health of the elderly, and furthermore, the importance of nutrition management thorugh oral health care of the elderly is increasd.

  • Focusing on the recently announced "KOSPI 200 ESG Index," this study intends to examine whether the "KOSPI 200 ESG Index" has any relevance to stock prices. Specifically, it was empirically analyzed whether companies included in the KOSPI 200 ESG index showed average abnormal return and cumulative average abnormal return of stock prices due to incorporation into the index. As for the research method, the case study was conducted using the return by the market model using the coefficient estimated by the OLS for the normal expected return. The study results are summarized as follows. First, the initial incorporation of a company into the KOSPI 200 ESG index showed significant positive(+) average abnormal return and cumulative average abnormal return. Second, the incorporation of a company into the KOSPI 200 ESG index showed significant positive(+) average abnormal return and cumulative average abnormal return. Through this study, it was confirmed that investors in the market are aware of ESG indicators as non-financial information, not just financial information. In addition, it can be said that the contribution of this study to the fact that investors perceive ESG index as information for investment. This study differs in that it uses the latest ESG index, but at the same time, it has limitations in that the study period is short and the study sample is limited.

  • There is great confusion over what constitutes public diplomacy (PD), who its actors are, and the relevance of non-state actors. In the Korean context, in addition to the general fuzziness of the concept, linguistic peculiarities of the terms gonggong and gongjung both of which refer to public, waegyo, which is interchangeably used for international affairs, foreign policy and diplomacy, and juche which is simultaneously used for actor and agent, add more layers of confusion. While the term PD in Korea is based almost entirely on Western conceptualization, these linguistic peculiarities prevent fruitful conversations among scholars and practitioners on PD. Against this background, this research note explores and addresses conceptual ambiguities that pertains to PD and the policy discourse on the topic, particularly on non-state PD in Korea. The paper draws on Korean government's PD-related policy documents and Diplomatic White Papers and all relevant academic articles found in Korean-language journals registered in the Korean Citation Index (KCI), which are analysed to gain an understanding of the PD-related policy discourse in Korea.

  • The inherent limitation of the conventional approaches in automatic indexing lies in the fact that they compute the relevancy between index terms and documents rather indirectly or relatively. As an alternative the anlaysis of document texts seeks a means of establishing a direct relevancy of the terms. More rigorous linguistic analysis will ensure better chance of relevancy. Various semantic topologies among terms may suggest the sufficient quality for relevancy. The enhanced and guaranteed relevance will allow the high precision of retrieval. Along with this line the on going project in KAIST pursues the user oriented retrieval system that spawns still may other issues that are not c o m n in traditional perspective.

  • The previous studies regarding the stock returns have advocated that industry effects exist over entire industry. As the industry categories are more rigid, the demand for predicting the industry sectors is rapidly increasing. The advances in Artificial Intelligence and Neural Networks suggest the feasibility of a valuable computational model for stock returns prediction. We propose a sector-factor model for predicting the return on industry stock index using neural networks. As a substitute for the traditional models, neural network model may be more accurate and effective alternative when the dynamics between the underlying industry features are not well known or when the industry specific asset pricing equation cannot be solved analytically. To assess the potential value of neural network model, we simulate the resulting network and show that the proposed model can be used successfully for banks and general construction industry. For comparison, we estimate models using traditional statistical method of multiple regression. To illustrate the practical relevance of neural network model, we apply it to the predictions of two industry stock indexes from 1980 to 1995.

  • The goal of this study is to generate a landslide susceptibility map using GIS(geographic information system) based method. A simple and efficient algorithm is proposed to generate a landslide susceptibility map from DEM(digital elevation model) and existing maps. The categories of controlling factors for landslides, aspect of slope, soil, topographical index, landuse, vegetation are defined, because those factors are said to have relevance to landslide and are easy to obtain theirs sources. The weight value for landslide susceptibility is calculated from the density of the area of landslide blocks in each class. Finally, a map of susceptibility zones is produced using the weight value of all controlling factors, and then each susceptibility zone is evaluated by comparing with the distribution of each controlling factor class.

  • Vibrations on the floor in a car are transmitted to the foot, hip, and back from the seat. Human body recognizes these vibrations, but the sensitivity for each vibration is different. To evaluate these vibrations, RMS(root mean square) of accelerations, VDV(vibration does value) are commonly used. The ride comfort evaluation is usually carried out by experiments of real cars which are expensive. The purpose of this paper is to briefly review the status of several ride vibration standards and criteria having relevance to construction machinery vehicles and to suggest recommendations for the effective use of such criteria in vehicle / component development.
