In this study, we gave 132 high school students fifteen probabilities and nine statistics problems of the Korean College Scholastic Aptitude Test and then analyzed their answer using the classical test theory and the item response theory. Using the classical test theory (the Testian 1.0) we get the item reliability ($0.730 \sim 0.765$), and using the item response theory (the Bayesian 1.0) we get the item difficulty ( $-2.32\sim0.83$ ) and discrimination ( $0.55\sim 2.71$). From results, we find out what and why students could not understand well.

Purpose: This study was done to identify the relationships among diabetic health leader attitude, diabetic knowledge, and health conservation in highly educated elders. Methods: The participants were 119 elders aged 65 or more who were attending the senior welfare centers in D and K City and had at least a high school degree. Data were collected from June 10 to July 7 in 2013. Data analysis included one-way ANOVA, independent t-test, Pearson's correlation, and stepwise multiple regression, done with the SPSS/WIN 19.0 program. Results: A positive correlation was found among diabetic health leader attitude, diabetic knowledge, and health conservation. Health conservation explained 26% (${\beta}$=.31) and diabetic knowledge explained 2% (${\beta}$=.18) of the variance in diabetic health leader attitude. Conclusion: The results indicate that to increase diabetic health leader attitude among highly educated elders, health leader programs are needed for increasing their diabetic knowledge and health conservation.

SNS는 오프라인의 인간관계를 온라인 공간으로 가져와 일상 및 관심사를 공유하여 인간관계를 형성하도록 하는 서비스이다. 특히, SNS를 통한 마케팅은 비용이 오프라인에 비해 확실히 저렴할 뿐만 아니라, 확산력은 다른 어떤 매체와 비교할 수 없을 만큼 크다. 따라서 많은 기업들이 SNS를 광고 플랫폼의 한 영역으로 인식하고, 이를 통한 마케팅에 꾸준히 투자하고 있다. 또한, 스마트폰 보급의 확산과 함께 SNS를 이용하는 청소년들이 급속도로 증가해가고 있으며, 이에 따라 SNS 광고에 대한 노출 정도 또한 높아지고 있다. 하지만 청소년들은 자신의 소비결정에 대한 가치관 확립이 불완전하여 외부 요인들이 구매의사에 미치는 영향이 크기 때문에 SNS 광고는 청소년들에게 적지 않은 영향을 줄 것이라고 판단되었다. 따라서 본 연구에서는 청소년들의 구매행동에 SNS광고가 어떤 영향을 미치는지 알아보고자 한다.

This paper develops and builds an Integrated Assessment System for National Competency Standard Professional Basic. The integrated evaluation system for basic job competency in the National Competency Standards is developed to conduct examination by means of computers, smartphones and tablet PCs. The system can be used for the basic job competency test, examination for online cyber universities, job competency examination for enterprises, and the listening, reading, and speaking test in the foreign language proficiency examination and is even better in terms of facility investment and saved operating costs as well as efficient use of spaces in comparison with conventional evaluation schemes. Even greater synergy effects can be achieved by providing support for the integrated evaluation system for basic job competency in connection with the NCS qualification system. The evaluation system has been tested and practiced at a specialized high school and can be applied to the NCS education evaluation of the college and four-year college and to the selection examination of new employees of the company.

We show that if a finite group G acts freely with homotopically trivial translations on a 3-dimensional nilmanifold 𝓝_p with the first homology ℤ² ⊕ ℤ_p, then either G is cyclic or there exist finite nonabelian groups acting freely on 𝓝_p which yield orbit manifolds homeomorphic to 𝓝/𝜋₃ or 𝓝/𝜋₄.

Street vended food (SVF) includes food and beverages prepared and sold outdoors or in public areas by street merchants for consumption on the scene or later without further preparation. Due to its low price and convenience, SVF has been popular in Korea for a long time, particularly with high school students. Beyond Korea, SVF is also popular in southeast Asia and southern Africa in the form of ready-to-eat food. This study on high school students, who are main consumers of SVF in Korea, focused on the factors that affect consumer loyalty. The study was performed by questionnaire and used AMOS software to develop a structural equation model. The results of verifying the model's fidelity were $X^2$=685.989, df=261, GFI=0.851, AGFI=0.814, NFI=0.901, CFI=0.907, RMR=0.048, indicating a satisfying structural model. SVF quality and service, emotional response, and the physical environment had a statistically significant effect on consumer loyalty. In contrast, SVF sanitation had no statistically significant effect on consumer loyalty. Based on these results, the sanitary management of SVF needs to be addressed immediately combined with education for SVF providers to maintain a clean environment.

The Online business model for purchasing agent service is getting more popular. However, consumers perceive more risk when buying products from foreign online purchasing agents (FOPA) than from common online sellers (COS). This study focuses on finding out how consumers manage risk when they perceive risk and what different risk-reliever strategies they use when buying from high-risk FOPA and low-risk COS. This study has proved the following two. First, when consumers perceive risk at online purchasing, they tend to select risk-reliever strategies, such as the use of communication media, online assurance mark, seller's record, and secure payment to mitigate risk. With the application of those risk-reliever strategies, they built trust with the seller. Second, risk-perception of FOPA influences usage of communication media and check of online assurance mark more strongly than that of COS. On the contrary, risk-perception of COS influences the check of seller record more strongly than that of FOPA. This study helps to explain why FOPA is proliferating, despite its inherent high risk due to the fact that buyers and sellers are separated in time and space and that buyers and sellers have different social and cultural backgrounds. This study also helps managers of E-commerce to relieve consumer's risk-perception and to build trust.

Purpose - This paper examines how the consumer animosity of partner country influences the purchase of foreign products. We analyzed news sentiment to determine whether Chinese consumer's animosity affect the purchase of the products made in Korea around the time when the U.S. Terminal High Altitude Area Defense missile system was deployed in South Korea. Design/methodology - To measure the tone of Chinese consumer animosity more carefully, we utilized a text mining technique of the Chinese language to read the public's opinion. Using Chinese news paper's editorials of 2015.1-2018.10, we analyzed the sentiment toward Korea and regressed it with Korean export to China. Findings - Empirical results report that Chinese consumers tended to reduce their purchase of consumer goods from Korea when the animosity increased, that is, the sentiments of Chinese news editorials were negative. In contrast, the animosity did not affect the purchase of Korean intermediates or raw materials. We further analyzed the effect by dividing the animosity into three categories; politics, economics, and culture. Among these groups, political news exhibits a unique effect on Chinese purchase on consumer goods from Korea. Originality/value - Existing literature on animosity models has measured the animosity by collecting the consumers' opinions through survey at a given time point, whereas it is measured by analyzing the tone of the press release by sentiment analysis during the time period around the event occurrence in this study.

It has long been shown that Korean EFL students have not practiced extensive reading in school curriculum. Their vocabulary knowledge is limited and a tool for measuring text readability for them has hardly been developed and used. The study aimed to check the current situations on the above issues and develop a reading framework appropriate for extensive reading within the national English curriculum, including the Readability Formula in Korean EFL contexts (KRF). The study consists of four steps. The study does a survey to check the current Korean EFL situations on the issues, suggests a new vocabulary learning size, develops a readability formula as a tool for measuring text difficulty based on the newly suggested vocabulary size, and finally validates the formula with various kinds of English books, including the primary and secondary school English textbooks. It is expected that this study will provide a model for the vocabulary size and the readability index for extensive reading in EFL contexts.

Purpose: This descriptive research was carried out to identify how high school students' attitude to death and their meaning of life were affected by hospice volunteering and death education. Methods: This study is based on a structured questionnaire designed for 180 high school students who were given death education while doing volunteer work at non-profit hospice hospitals and another 288 high school students not doing any hospice volunteer work. The collected data was processed by the SPSS 20.0 program and then analyzed by $x^2$ test, t-test and ANOVA test. Results: High school students' attitude to death and their meaning of life showed significant differences depending on whether or not they had volunteered at hospice hospitals. The group with hospice volunteering experience tended to be more negative about death and have a higher meaning of life compared to those without hospice volunteering experience. Students with proper hospice recognition made up 52.4%, those who expressed hopes to receive hospice-care themselves if necessary accounted for 70.5%, and those who said they would like to take care of their family members either at home or at a hospice center if any of them got incurably sick comprised 59.0%. Those who thought dignified death is to be with one's family or any other meaningful person were 47.6% and 18.5% of the students thought that 'thinking they had led a meaningful life' was the core of a dignified death. Conclusion: Given the above results, it became clear that hospice volunteering and death education can affect high school students' meaning of life and their attitudes toward death.
