Objectives: To investigate emotional characteristics of healthy adults using the Core Seven Emotions Inventory-Short Form (CSEI-s) and to investigate the correlation between the CSEI-s and Korean version of the Perceived Stress Scale (K-PSS). Methods: Overall, 2,178 healthy adults aged ≥19 years who completed the CSEI-s and K-PSS in a nationwide multicenter study were included in this study. One-way analysis of variance was performed to identify associations of seven emotions with sociodemographic characteristics. Bonferroni corrected post-hoc tests were performed for multiple comparisons. Pearson's correlation analyses were conducted to examine the correlation between each emotion and stress. Results: Scores of all emotions except for joy (喜) and stress were significantly greater in women than in men. However, the score of joy (喜) in women was significantly less than that in men. There were significant differences in joy (喜), thought (思), depression (憂), fear (恐), and fright (驚) according to age groups in both men and women. The score of depression (憂) was significantly lower in women attending or graduating from graduate school than in those attending or graduating from undergraduate school. Significantly lower scores in joy (喜), thought (思), depression (憂), sorrow (悲), fear (恐), and fright (驚) were observed in married men than in single men. There were significant positive correlations between depression (憂) and stress and between sorrow (悲) and stress in both men and women. Conclusions: There were significant associations of seven emotions with sociodemographic characteristics in healthy adults.

This study analyzed the impact of recirculation on high-concentration PM_2.5 in the coastal area. Through the analysis of observational data, it was observed that the development of sea breeze led to an increase in PM_2.5 and SO₄^2- concentrations. Hysplit backward trajectory analysis confirmed the occurrence of air mass recirculation. Results from WRF and CMAQ numerical simulations indicated that pollutants transported from land to sea during the night were re-transported to the land by daytime sea breeze, leading to high-concentration PM_2.5 in Busan. To quantitatively investigate the recirculation a recirculation factor (RF) was calculated, showing an increase in RF values during high-concentration PM_2.5 episodes. However, the RF values varied slightly depending on the time resolution of meteorological data used for the calculations. This variation was attributed to the terrain characteristics at observation sites. Additionally, during long-range transported days leading to nationwide high-concentration PM_2.5 events, synoptic-scale circulation dominated, resulting in weaker correlation between PM_2.5 concentration and RF values. This study enhances the understanding of the influence of recirculation on air pollution. However, it is important to consider the impact of temporal resolution and terrain characteristics when using RF for evaluating recirculation during episodes of air pollution.

KIGAM has surveyed most of the Korean territory since 1982 using airborne gamma-ray spectrometry, and complete the nationwide scale map in the near future. However, since the duration of survey is too long and the conditions of survey is not consistent, the data does not have physical consistency. In addition, the window counts (count/sec) were recorded instead of potassium, uranium and thorium radioelement concentrations. Thus, the data could not be registered to the International Atomic Energy Agency (IAEA) radioelement datum. This limits the usefulness of the data and it is not possible to easily combine surveys into regional compilations or make quantitative interpretations between different survey areas. To solve these problems, we undertook a test baseline survey over Jincheon-Eumseong area, to level the different two sets of data and to map radioelement concentrations. This survey confirms to IAEA radioelement baseline. The method and procedures of data leveling prepared by this study improve the usefulness and usability of the radiometric data, and make it enable to compile the nationwide scale radioelement concentration maps.

The purpose of this study was to examine the effects of perceived fit and brand transfer on extension evaluation in luxury fashion brands. The instrument for this research was a self-administered questionnaire based on a previously developed scale. The variables addressed in this scale included perceived fit, brand value for both parent brand (clothing) and extension brand (home line), extension brand association, and purchase intention of the product in extension brands. The participants in this research comprised of 215 female consumers between the ages of 19 and 51 demographically distributed nationwide. Data were analyzed by descriptive statistics, paired t-test, factor analysis, and regression analysis via SPSS 12.0. Findings showed that brand value consisted of two factors: cognitive and hedonic value in luxury fashion brands. Parent brand value was significantly related to perceived fit with a positive effect on brand association and hedonic value in extension brands. With respect to brand transfer, cognitive value of the parent brand increased the extension brand's cognitive value, while hedonic value of the parent brand increased the extension brand's hedonic value. In addition, purchase intention of the product in the extension brands was determined by the perceived fit and hedonic value of extension brands. This study also discusses the managerial implications for marketers in developing effective luxury brand extensions into new product categories, which leads to a synergy effect in building brand equity in the luxury fashion market.

Background: Attitudes toward breastfeeding in public are one potential barrier to optimal breastfeeding rates and durations. Method: Questions about breastfeeding experience and attitudes toward breastfeeding in public were asked in face-to-face interviews as part of the Korean Academic Multimode Open Survey (KAMOS), May-July, 2017. The response rate was 65.8% (2000 respondents nationwide). Results: A majority of Koreans disagreed (1 or 2 on a 4-point scale) with the statement "Women should not breastfeed their child in open, public places" (53.9%) and agreed (3 or 4 on the 4-part Likert scale) with the statements "I do not feel uncomfortable seeing women breastfeed their child in open, public places" (64.0%) and "Breastfeeding a baby, instead of letting the baby cry, in public places is better for other people" (71.8%). However, despite these generally positive attitudes, the majority also said that they would not breastfeed in public (57.4% of women) or, in the case of men, would not want a close female relative to do so (63.8% of men). Breastfeeding in public was positively correlated with the duration of breastfeeding. People were more positive about breastfeeding in public if they: were parents; did not use formula and breastfeeding a similar amount; had children who had been breastfed in public; were older; were Buddhists rather than Christians. An attempt was made to compare attitudes toward breastfeeding in public and breastfeeding durations internationally, but was inconclusive due to not perfectly comparable data. Conclusion: Our results may be useful in planning public health campaigns in South Korea or future attempts at international comparisons to better understand and address the effect of public opinion regarding breastfeeding in public on breastfeeding rates and durations.

Objectives: The purpose of this study is to develop a case review form for detecting adverse events through a medical records review in hospitalized patients in South Korea. Methods: To develop the case review form, several literatures were reviewed, first. Through the clinical expert meeting, screening criteria were selected and case review form was developed. Result: The Korean version of case review form consisted of the review form-1 for adverse event screening and form-2 for adverse event identification. The applied methodology for the case review form is determined according to the previous studies. For example, the method used in the first stage review is nurse review. Furthermore, the National Coordinating Council for Medication Errors Reporting and Prevention index is used to categorize disability, and a scale of 1 to 6 was used in the causation scores and preventability scores, respectively. Through the clinical expert meeting, a total of 41 screening criteria were selected. Conclusion: The Korean specific case review form was developed for detecting adverse events in hospitalized patients. The results from this study can be used in a large-scale study regarding the nationwide incidence of adverse events.

This study aims to examine the relationship between the improvement of the income distribution index from the late 1980s to the 1990s and large-scale housing supply projects such as the 2 million housing construction project. Looking at Korea's economic development in terms of income growth and distribution, GDP has continuously increased since the establishment of the government, especially in the late 1980s. The Gini Index, a representative income inequality index, rapidly deteriorated in the early 1970s, and gradually improved from the late 1980s. The 2 million housing construction project, announced in 1988, supplied a third of the existing nationwide housing stock of 6.5 million units in three years. The project cost was 65 trillion won, equivalent to 50% of Korea's GDP at the time. This study questioned whether the ratio of the number of employed workers in the construction industry was a variable directly affecting the Gini Index. To verify this, the causal relationship between the proportion of employed workers in the construction and manufacturing industries and the Gini Index from 1979 to 2008 was statistically analyzed. For this, the ARIMA model was established for each variable, and the correlation of their residuals was verified. The 2 million housing construction project had the effect of improving income inequality in terms of rising wages for production workers and creating jobs for the low-educated and low-income class. During the project period, the number of middle-income earners increased sharply, and the income gap between the high-income and low-income earners greatly decreased. The expansion of the construction volume can be used as a powerful and direct policy tool for improving income distribution. However, the effect may be limited. When the proportion of workers exceeds the threshold, the effect is weakened.

Nationwide supercomputing infrastructures in Korea consist of geographically distributed supercomputing clusters. We developed High-Throughput Computing as a Service(HTCaaS) based on these distributed national supecomputing clusters to facilitate the ease at which scientists can explore large-scale and complex scientific problems. In this paper, we present our mechanism for dynamically managing computing resources and show its effectiveness through a case study of a real scientific application called drug repositioning. Specifically, we show that the resource utilization, accuracy, reliability, and usability can be improved by applying our resource management mechanism. The mechanism is based on the concepts of waiting time and success rate in order to identify valid computing resources. The results show a reduction in the total job completion time and improvement of the overall system throughput.

This study is about the effectiveness of Jahwal consulting. We analyzed 275 self-supporting participants of 58 self-supporting companies in eight wide-area self-supporting centers nationwide. After consulting by conducting a questionnaire before consulting, we conducted a questionnaire to analyze the differences. The measurement variables consisted of 3 variables and 6 subparameters. The top variables are interpersonal relationships, organizational systems, and self-help business will. The sub-elements are interaction, communication between members, horizontal leadership, organizational stability, personal suitability and developability. The questionnaire was analyzed using SPSS 21.0, frequency analysis, and t-test. The purpose of this study is to verify the effectiveness of consulting conducted by Jahwal institutions. For this reason, we developed a measurement scale, and analyzed changes before and after consulting using that scale. As a result of the analysis, it was found that self-help consulting is effective. It was also analyzed that there was mode significance in the analysis by gender, age, region and educational background.
