  • Purpose - This study examines the effects of purchasing factors of consumers based on customer satisfaction and repurchasing intention buying through Internet shopping malls. The subject of this study are Chinese residents who have lived over a year in Korea. Research design, data, and methodology - In this study, former research related with internet shopping malls' customer satisfaction and repurchase intention was revised. Based on past research, the internet shopping mall purchasing factors divided to 4 factors; factors of product, price, service, and promotion. 5 hypotheses were made. They are

    Product factors of internet shopping malls have meaningful effect to customer satisfaction,

    Price factors of internet shopping malls have meaningful effect to customer satisfaction,

    Service factors of internet shopping malls have meaningful effect to customer satisfaction,

    Promotion factors of internet shopping malls have meaningful effect to customer satisfaction,

    Customer satisfaction factors of internet shopping malls have meaningful effect to customer repurchase intention. Measurements developed 4~5 items to each factor and questionnaires were made. The survey was conducted on 1,000 Chinese people. Out of 292 surveys, 9 were excluded which responded nothing or were unfilled. Finally 283 surveys were used in empirical analysis with SPSS 22.0 statistical program. Hypotheses were verified by structural equation modeling. Results - The following conclusions are shown in the empirical study. First, the service and promotion factors of internet shopping mall have effects on customer satisfaction. Second, customer (Chinese people who live in Korea) satisfaction have effects on repurchase intention. Third, the products value and price level of internet shopping mall have strong effects on repurchasing intention. Conclusions - There are suggestions that Chinese customers satisfied with Korean internet shopping malls might increase their royalty to the shopping malls as possibility of repurchase arises. This study has differentiating points with preceding researches that subjected residents in Korea. But there are limitations that this study also used purchasing factors used in preceding studies. Also this study has limitations, such as generalization in global market circumstances because this study subjected only Chinese people and not global customers. Therefore, further study executed complementary with those limitations would be an interesting study.

  • This study examinedthe adaptive flexibility of North Korean adolescent defectors in order to examine how they should see themselves and cope with various situations, and analyzedthe effect of their resilience on their self-esteem and social problem-solving ability. The study subjects were 223 North Korean adolescents (10 - 25 year olds) living in South Korea. Data analysis was conducted using SPSS 23.0 and AMOS 23.0 statistical programs. The study results showed that the resilience of North Korean adolescents had a statistically significant effect on their self-esteem and social problem-solving ability. In particular, resilience had a high correlation with self-esteem, and self-esteem had a high correlation with social problem solving ability. In addition, self-esteem was the mediating factor between resilience and social problem-solving ability. The self-esteem of North Korean adolescent defectors played a particularly important role. Therefore, professional protection and support should be provided with the help of related experts such as youth leaders and counselors who would be able to enhance the self-esteem of North Korean adolescent defectors.

With oral care programs, conducting follow-up surveys on multicultural women's oral health condition to figure out the condition and examining improvements and related factors, it tried to contribute to building oral care programs for the future of multicultural families. The study participants were recruited from multi-cultural family center in a metropolis, they were treated their oral conditions at local dental clinics during a year. All participants were 608 people, and among them, one year follow-up sample was 40 women. An interview questionnaire was used to collect information on socioeconomic level and general characteristics related to oral status, through oral examination were conducted to obtain dental caries experience and periodontal conditions. The statistical analysis was done by using the SPSS 20.0 program. Comparing the results between before and after oral health program for an year, DMFS, DS, FS, DT, FT and CPI were significantly decreased during a year. The present study increases interest about multicultural women and family and we look forward to using it as basic data for oral health promotion.

  • Purpose: In patients with altered mentality caused by drugs or unknown causes, ammonia is checked to facilitate differential diagnosis or diagnose hepatic coma. This helps early prevention and treatment of brain damage due to hyperammonemia. This study was conducted to evaluate clinical characteristics of intoxicated adult patients with hyperammonemia. Methods: We evaluated 95 patients with hyperammonemia among intoxicated patients above the age of 15 who visited our ED from January 2013 to December 2015. We analyzed the demographic characteristics and type of poisoning substance, reason for ingestion, toxicological characteristics such as elapsed time from ingestion to hospital visit, lab, clinical progression and complications. Data were evaluated using the student's t test or Mann-Whitney U test for continuous variables, and Chi-square test and Fisher's exact test for frequency analysis of categorical variables. Results: When compared to healthy individuals, patients with hyperammonemia showed statistical significance on their SOFA score (p=0.016) and poison severity score (p<0.001). Additionally, patients with hyperammonemia showed significantly different initial serum AST level (p=0.012) and maximum serum AST level during the hospital stay (p=0.026) when compared to healthy individuals. Moreover, individuals with sustained hyperammonemia compared to transient hyperammonemia showed clinically significant SOFA scores (p<0.001), poison severity scores (p=0.007), mortality rates in the ICU (p=0.021), as well as different duration of hospital stay (p=0.037), serum creatinine level (p=0.002), erythrocyte sedimentation rate (p=0.025), and serum myoglobin (p=0.015). Conclusion: Most poisoning-induced hyperammonemia cases were transient and recovered without special treatment. Therefore, hyperammonemia is almost non-specific among poisoning patients.

  • This paper analyzed and compared the service level and satisfaction of the sidewalks in collector roads from 6 different location, which has a lot of volume of pedestrians. For the study, it performed an investigation of road geometry, flow, research about satisfaction of walking and video recording. Based on this data, this study computed the service level of the sidewalks and pedestrian satisfaction. This study made a sense of correlation between service level and satisfaction. Also it focused on factors influencing on the effectiveness of satisfaction. This study also analyzed the change of walking behavior chracteristics according to the change of the level of satisfaction. This study adopted Multi-Modal Level of Service(MMLOS) method, because it could consider more factors. This study reached the conclusion that MMLOS method cannot completely reflect the level of pedestrian satisfaction. We have to consider more factors than in the current system for use in the development of sidewalk design. The result of this study is expected to reflect the pedestrian satisfaction in future sidewalks design.

  • Objectives: This study estimated the adult Korean daily intake of acrylamide (AA) and investigated its relationship with demographic, lifestyle and dietary habits by using urinary concentrations of N-acetyl-S-(2-carbamoylethyl)-cysteine (AAMA). Methods: Human data (n=1870) was collected in a nationwide cross-sectional biomonitoring program representing the population (18-69 years) residing in South Korea. Urinary AAMA was analyzed with a LC-MS/MS system. Daily intakes of AA were estimated using mass daily AAMA, which was calculated through urinary AAMA concentration and daily creatinine excretion. Statistical analysis was performed with SAS procedures for calculating geometric means, confidence intervals and the exponentiated beta coefficient of multiple linear regressions. Results: Daily intake of AA was estimated at $0.475{\mu}g/kg$ body weight (BW) per day (95% confidence interval (CI): 0.447-0.503). In the case of current smokers, AA intake was $0.957{\mu}g/kg$ BW per day (95% CI: 0.847-1.067), which was significantly higher than that of former smokers and never smoked (p<0.0001). The strong affecting factors were age (95% CI: 0.68-1.14; p=0.0180), education level (95% CI: 1.05-1.42; p=0.0163), body mass index (BMI) (95% CI: 1.00-1.82; p<0.0001), and smoking status (95% CI: 0.97-3.05; p<0.0001). Korean dietary habits increasing AA intake were coffee (p=0.0005), cup noodles (p=0.0010) and canned foods (p=0.0005). Meanwhile, foods decreasing AA intake were fresh fruit (p=0.0076), cooked beef (p=0.0335) and cooked pork (p=0.0147). Conclusion: The Korean daily intake of AA in adults was estimated to be similar with those found in developed countries. The factors increasing daily AA intake were coffee, cup noodles and canned foods, and decreasing factors were fresh fruit, cooked beef and cooked pork.

  • The purpose of this study is to make formulated examination and analysis about major two factors of dental hygienic students' satisfaction at clinical training, i.e. the contents of clinical training and their duties satisfaction, so that it can provide a basic reference material for more efficient clinical training and education. This study conducted a questionnaire survey for 427 students who were taken via simple random sampling from sophomore and junior dental hygienic students, who already experienced in clinical training courses, at some universities(and colleges) in Metropolitan and province areas. The data collected from this survey were analyzed using SPSS WIN 11.5, in parallel with t-test, one-way ANOVA and ${\chi}^2$(Chi-square) test. It was found that our students didn't feel so much satisfied at clinical training(satisfaction level = 3.34). Overall, they didn't show any significant satisfaction with the contents of training and the experiences in clinical training duties. Our dental hygiene students showed relatively low satisfaction with the contents of clinical training as well as satisfaction at clinical training duties, which ie that current clinical training in dental hygienics still remain at the level of simple assistance for dental treatment.

  • The aim of this study was to investigate adult individuals' perceptions on the association between chronic diseases and oral health provide basic data required for motivating individuals to follow ideal oral health behaviors and boost their interests in oral disease prevention and treatment. Subjects in their 20s to 50s were selected through the convenience sampling method and eleven questions were set as factors and answered via self-administered questionnaires. To determine statistical significance, analysis of variance was used with the level of significance set at 0.05. The subjects' perception of the association between chronic diseases and oral health were analyzed with respect to their health behaviors. Individuals with relatively higher stress levels demonstrated higher levels of perception levels (p<0.05). Public education regarding the association between chronic diseases and oral health has not been ideally effective in South Korea. Thus, the general public's perceptions of the association between chronic diseases and oral health should be revised. In addition aspects regarding this matter should be enhanced within oral health education programs which often only focus on demonstrating the importance of oral health management so that individuals can get sufficient information on the association between chronic diseases and oral health.

  • The results from the Global Positioning System (GPS) measurements of the Mobile Observation Vehicle (MOVE) on the eastern coast of Korea have been compared with REFerence (REF) values from the fixed GPS sites to assess the performance of Precipitable Water Vapor (PWV) retrievals in a kinematic environment. MOVE-PWV retrievals had comparatively similar trends and fairly good agreements with REF-PWV with a Root-Mean-Square Error (RMSE) of 7.4 mm and $R^2$ of 0.61, indicating statistical significance with a p-value of 0.01. PWV retrievals from the June cases showed better agreement than those of the other month cases, with a mean bias of 2.1 mm and RMSE of 3.8 mm. We further investigated the relationships of the determinant factors of GPS signals with the PWV retrievals for detailed error analysis. As a result, both MultiPath (MP) errors of L1 and L2 pseudo-range had the best indices for the June cases, 0.75-0.99 m. We also found that both Position Dilution Of Precision (PDOP) and Signal to Noise Ratio (SNR) values in the June cases were better than those in other cases. That is, the analytical results of the key factors such as MP errors, PDOP, and SNR that can affect GPS signals should be considered for obtaining more stable performance. The data of MOVE can be used to provide water vapor information with high spatial and temporal resolutions in the case of dramatic changes of severe weather such as those frequently occurring in the Korean Peninsula.
