Agar, a heterogeneous polymer of galactose, is the main component of the cell wall of marine red algae. It is well established as a safe, non-digestible carbohydrate in oriental countries. Neoagarooligosaccharides (NAOs) prepared by hydrolyzing agar by microbial β-agarase have been reported to show safety. However, their immunological effects have not been reported yet. Thus, the objective of this study was to investigate immune enhancing effects of neoagarooligosaccharides (NAOs) from marine red algae Gelidium elegans in mice by performing ex vivo experiments. Six-week-old mice were fed ad libitum. NAOs were orally administrated at three different concentrations (100, 500, and 2,500 mg/kg B.W./day) twice a week for four weeks. The group fed with NAOs at 2,500 mg/kg showed the highest proliferation of splenocytes and production levels of cytokines (IL-1β, IL-6, TNF-α) in the ex vivo experiment. In conclusion, NAOs can enhance immune function, increase proliferation of splenocytes, and increase cytokine production by activating macrophages in mice.

The purpose of this study is to evaluate the application of a web-based cost management competency enhancement program (Web-CMCEP) on nursing students. Medical services are limited and essential for maintenance of human basic life. In order to improve the quality of human life, cost management competency that enable efficient allocation of medical resources are essential. This study adopts a randomized controlled pre/post repeated measure design. The sample comprised 39 nursing students in the web-group and 35 in the textbook-group. Experimental group and control group learned respectively with Web- CMCEP and textbook for 4 weeks. The research variables were measured at 4 times: pre, post, after 4 weeks of intervention, and after 8 weeks of intervention. Data were analyzed using χ2 -test, t-test, paired t-test, repeated measures ANOVA, Friedman test, and Wilcoxon signed rank test. Significant differences were found in cost management knowledge. The web-group showed higher cost management knowledge than the text-group. At different measuring points, the Web-CMCEP led to significant increases in the following: cost management knowledge, cost management attitude, cost management behavior, cost management self-efficacy, and entrepreneurship. Based on the findings, we suggested utilizing the Web-CMCEP as a prototype in developing education programs to improve nursing students’ cost management competency and to support nursing start-ups.

Despite the recognized importance of morphological knowledge to literacy outcomes such as vocabulary knowledge and reading comprehension, two of its subconstructs— morphological awareness and morphological processing—have received comparatively little attention. In response, the aim of the study reported here was to examine how the relationships between morphological awareness and morphological processing, especially in terms of morphological transparency and morphological frequency, contribute to the vocabulary knowledge and reading comprehension of 62 native Korean-speaking secondary school students—27 eighth-graders and 35 tenth-graders— learning English as a foreign language. The students’ performance on the Test of Morphological Structure and the Word Reading Test was assessed to gauge their compounding awareness, inflectional awareness, vocabulary knowledge, and reading comprehension. The results indicated that the students’ performance was varied depending on morphological transparency and frequency. In addition, it was not morphological processing, but rather morphological awareness that explained variances in vocabulary knowledge and reading comprehension, when compounding awareness and inflectional awareness were controlled for. This paper discusses what such findings imply for teaching English as a foreign language to Korean learners.

목적: 안경광학과 전공 학생과 전문가를 대상으로 스마트 기반 국가시험에 대한 인식에 대하여 알아보고자 하였다. 방법: 안경광학 전공 학생, 교수, 임상전문가(안경사)로 구성된 171명을 대상으로 지필평가방식과 스마트 기반 멀티미디어 문항이 포함된 평가방식(SBT)에 대한 인식을 조사하기 위하여 설문조사를 실시하였다. 결과: 안경관련 전문가 집단의 SBT에 대한 인식은 다른 보건의료직종의 전문가 집단보다 낮은 것으로 나 타났지만, 안경사국가시험에서 지필평가와 SBT 평가 두 시험 체제는 차이가 없을 것이라는 의견이 44.4%, SBT 평가체제가 더 좋다는 의견이 37.4%로 지필평가(31.0%) 보다 높게 나타났다. 스마트 기반 시험의 가장 긍정적인 측면은 시험에 소요되는 시간 단축을 최대 장점으로 인식하는 것으로 나타났으며, 멀티미디어 문항의 긍정적인 측면은 임상현장에서의 수행능력을 효과적으로 평가할 수 있다는 것으로 나타났다. 또한, 교수집단의 경우 응시자의 임상수행능력을 보다 정확하게 평가할 수 있다, 졸업 후 임상현장에서 업무를 수행 하는 과정에 도움이 된다, 수행평가가 용이하다는 점에서 임상전문가보다 더 긍정적으로 반응하였다. 결론: 지필시험에서 사용하고 있는 선택형 시험문항은 문제해결능력보다는 직무를 수행하는데 필요한 관련 지식을 기억하거나 이해하고 있는지를 주로 평가하고 있어, 해당 직무의 실제성 또는 현실성을 반영하는 시험이 되기 위해서는 본 연구결과를 반영한 SBT 체제로의 전환이 필요한 것으로 나타났고, 이를 위한 타당성 연구가 지속적으로 이루어져야 할 것이다.

Social networking sites (SNS) are defined as web-based services that enable consumers to create a public profile and a list of contacts with whom they share a social network (Kang et al., 2014). On SNS sites, consumers can find the right product, obtain advice from people, make purchases, post product recommendations, reviews and photos, and create SNS communities (Shen, 2008). The shopping motive acts as an important trigger to browse for products on social media websites. Product browsing over social media sites could influence the intention of future purchase and sharing information of product and brand with friend and acquaintances. For companies related to social media business, both intention to purchase and information sharing are crucial elements. However, few efforts have been made to identify the factors driving consumer intentions to purchase and word-of-mouth of fashion products on social media sites. The objectives of this study were to determine the factor to facilitate product browsing and to find out the causative relationship among influential factors and consumer intentions to purchase and word-of-mouth of fashion products on social media sites. The instrument was developed based on the previous literatures (Brien, 2010; Park, et al., 2012; To, 2007; Woo & Hwang, 2013) and each item was measured by five-point Liker type scales. A total of 269 data were collected during a regularly scheduled class in universities, who have experienced to purchase fashion products or make a product review on social media sites. Mean age of the respondents was 22.3 years old. Nearly 75.3 percent of the subjects were women, and more than half of the respondents (61.6%) have purchased the products (e.g., apparel, shoes, etc.) on social commerce sites over three years. The structure equation model analysis was conducted by AMOS 23.0 using a correlation matrix with maximum likelihood approach. The structural equation model was relatively acceptable (chi-square value = 136.30, df = 66, p = .000; GFI = .94, AGFI = .91, RMR = .05). Cronbach's alphas were ranged between .83 and .87. This result suggests that utilitarian shopping motives have influenced directly product browsing, purchase intention, and word-of-mouth intentions of fashion products on social media sites. The more product browsing on social media sites, the more intended to purchase and word-of-mouth of fashion products with friend and acquaintances. It implies that consumer with utilitarian shopping motives are likely to more browse, and then to more purchase and write the review of fashion products on social media sites. However, consumers with hedonic shopping motives are prone to more write the review of fashion products to their friends and acquaintances without product browsing or purchase intention on social media sites.

This study aimed to examine Korean learners’ language development under four different learning conditions with the aid of input enhancement. Four types of learning conditions were carefully manipulated: (1) more incidental, (2) less incidental, (3) rule-search, and (4) instructed. The two incidental groups were told to understand the meaning of the passage, while the rule-search group was asked to find the embedded rule while reading. The instructed group received explicit rule instruction before the reading task. A total of 141 11th grade high school students in South Korea participated in this study and took pre/post grammatical judgment tests, a reading comprehension test, and a guided sentence composition test. The findings indicated that incidental rule learning in Korean EFL was possible while their attention was on meaning. In addition, the degree of rule learning and output was maximized when explicit instruction was presented. However, there was no significant difference in the participants’ overall reading comprehension. Along with pedagogical implications, the three interface positions are also discussed.

본 연구는 결혼이주여성들과 국제결혼을 한 한국인 남편들의 경험을 살펴보았다. 연구 참여자들은 경기도와 충청남도에 거주하며, 이주여성과 결혼한 한국인 남편 15명으로 본 연구의 결과는 다음과 같다. 첫째, 결혼이주여성들의 남편은 음식문화와 문화 차이에 대해서 많은 어려움을 겪고 있으나 자녀교육에 있어서는 의연한 태도를 보이고 있었다. 국내거주로 인한 영향과 막연한 긍정적 기대감으로 자녀교육에 대해서는 덜 불안해하는 모습을 알 수 있었으며, 약간의 불안감만이 존재하였다. 둘째, 결혼 초기에 한국 남편들은 이주여성인 아내를 위해서 일상생활에 필요한 의사 표현이 가능할 때까지 인내하며 노력하는 모습을 보였다. 하지만 결혼 생활이 지속되면서 아내를 이해하고 배려하는 면보다는 한국인으로서 빠르게 동화되기를 더욱 바라고 있었다. 셋째, 결혼이주여성을 지원하는 건강지원센터 및 지방자치단체, 사회기관 등에서 한국 사회의 적응을 위한 다문화가정의 시간, 교통 등의 상황과 여건을 고려한 한글᠂ 음식᠂ 문화등과 관련된 현실적이며 살아있는 교육 프로그램이 필요하다. 한국사회에 성공적으로 적응한 결혼이주여성들을 위해 지원전문 교육기관에서 교육하여야 하며, 한국 문화에 대한 다양한 교육과 자국민들 간의 사회 연결망 구축으로 서 로에게 필요한 정보와 자원을 제공하는 역할을 담당하게 하여, 한국 사회 적응의 어려움을 극복해 나갈 수 있는 매개체로써의 역할을 하는 프로그램의 진행이 절실한 것으로 나타났다.

The online store attributes acts as an important trigger for e-impulse buying. Purchasing apparel products are often affected by irrational and emotional attraction making them one of the most frequent impulsively purchased items online. Triggered by ease access to products, easy purchasing, lack of social pressures and absence of delivery efforts, impulse buying occurs in approximately forty percent of all online expenditures. Impulse buying occurs when consumers experience an urge to buy a product, without thoughtful consideration why and for what reason one needs the product. However, few efforts have been made to identify the relationship among-store services attributes, emotions, browsing, urges to buy, and e-impulse buying of apparel products. The objectives of this study was to estimate a path model analysis for causative relationship among e-store service attributes, emotions, browsing, urges to buy, and e-impulse of apparel products. The instrument was developed based on the previous literatures (Park, et al., 2012; Verhagen & Dolen, 2011; Yang & Peterson, 2004)and each item was measured by five-point Liker type scales. A total of 250 data were collected during a regularly scheduled class in universities. More than half of the respondents (65.5%) were 18 to 21 years old. Nearly 65.5 percent of the subjects were women, and more than half of the respondents (63.8%) were below the sophomore. The path model analysis was conducted by AMOS 18.0 using a correlation matrix with maximum likelihood approach. An exploratory factor analysis revealed three types of e-store service attributes: Accuracy, Reliability, and Ease of use. The path model, which was estimated to examine causal relationships among variables (i.e. three types of e-store service attributes, emotions, browsing, urges to buy, and e-impulse buying), was relatively acceptable (chi-square value = 34.40, df = 13, p = .001; GFI = .98, AGFI = .93, RMR = .03). Cronbach's alphas were ranged between .83 and .87. This result suggests that emotions (e.g., positive and negative), browsing and urges to buy perceived by shoppers play important roles as mediators of the e-impulse buying of apparel products. Especially, the urge to buy apparel products was the most important mediator to trigger e-impulse buying. The consumers perceived the accuracy and reliability of e-store attributes were the more perceiving the urges to buy apparel products through the more positive emotions and then the more browsing at e-store. Also, the more ease to use of e-store perceived the more urges to buy apparel products. The more perceiving urges to buy at e-store were the more e-impulse buying of apparel products. This study provides retail managerial implications for stimulating e-shoppers' impulse buying of apparel products.

Historically the rise of contagious diseases and epidemics has been mainly caused by lack of food safety knowledge and negligence in personal hygiene. Food poisoning is an example that have been caused by lack of proper knowledge in food safety and personal hygiene. In order to prove this hypothesis, our team distributed a total of 225 survey sheets to middle school students. Survey questions mainly focused on the students' food safety knowledge, personal hygiene and regular dietary habits. We used 12 items to determine the stages of change in teenagers and divided into 3 stages of change: precontemplation stage (poor problem recognition), contemplation and preparation stage (some problem recognition), and action stage. Out of the 225 students surveyed, 105(47.1%) were male and 118 (52.9%) were female; 44.0% were in 7th grade, 33.0% in 8th grade, and 24.0% in 9th grade. In stages of change model, 3.8% were classified in pre-contemplation stage, 31.1% in preparation stage, and 65.1% in action stage. The awareness of the significance of food safety has a strong positive correlation with the stages of change food safety behavior (P<0.001), which suggesting our questionnaires regarding stages of change and food safety behavior were quite credential. Stages of change were also correlated with the consumption of unsanitary foods (P<0.01) and with the frequent hand washing (P<0.05). The stages of change showed a positive correlation with the food safety knowledge level (P<0.05). The four questions (out of 10) with the least percentage of correct answers were questions about the meaning of Norovirus (23.6%), the meaning of expiration date (43.6%), the meaning of food poisoning (36.4%), and proper food-handling (36.0%).

본 연구의 목적은 방과 후 원예활동이 저소득층 아동(1,2학년)의 자아존중감과 정서에 미치는 영향을 알아보고자 실시하였다. 그 결과 전체적으로 자아존중감이 상승되었음을 살펴볼 수 있다. 하위요인별로는 사회적 자아존중감과 학업적 자아존중감이 높아졌다. 반면 가정적인 자아존중감은 약간 하락한 것을 볼 수 있다. 원예활동이 학교생활에서는 긍정적인 변화를 가져왔으나 가정적인 부분까지는 아직 연결되지 못하였다. 적은 수의 아동을 개인적으로 교감하면서 원예치료를 실시하면 좀 더 의미 있는 결과를 기대할 수 있으리라 본다.
