This study was carried out to investigate the effects of grape seed oil on quality characteristics of pressed ham. Five different treatments were tested based on differences in the amount of grape seed oil added to the pressed ham. As a control, 10% back fat was added without any grape seed oil. For the first treatment, 10% grape seed oil replaced a portion of the lard component added to the pressed ham. For the 2nd, 3rd and 4th treatments, 20%, 30% and 40% of grape seed oil were substituted for lard, respectively. Pressed ham manufactured with grape seed oil was vacuum packaged and stored for 1, 7, 14,21 and 28 d at $4^{\circ}C$. Samples were analyzed for chemical composition, physico-chemical properties (pH, color) and texture characteristics. Typical chemical composition characteristics (crude protein, crude fat, crude ash) were not significantly different between control and grape seed oil treatment groups. Moisture content of grape seed oil treatment groups (GSO 30% and 40%) was significantly lower than that of controls (p<0.05). There was a not clear difference in pH between control and grape seed oil treatment groups. In the 21 d of storage, pH values of all treatments were significantly higher than those of other storage days. Meat color $(CIEL^*\;and\;b^*)$ of grape seed oil treatment group (GSO 40%) was significantly higher than that of control. Whereas meat color a value of GSO 40% treatment was significantly lower than that of control. It was not clearly changed as storage time increased. There was no significant difference in texture between control and grape seed oil treatment groups, and appeared to be unaffected by storage length. Based on these findings, we conclude that the chemical composition and texture characteristics of manufactured pressed ham were not affected by grape seed oil addition. These results also indicate that high-quality pressed ham can be manufactured with increased polyunsaturated fatty acid content.

This study was carried out to investigate the effects of olive oil on the quality characteristics of pressed ham. Five different treatments were tested based on differences in the amount of olive oil added to the pressed ham. As a control, 10% back fat was added without any olive oil. For the first treatment, 5% olive oil replaced a portion of the lard component added to the press ham. For the 2nd, 3rd and 4th treatments, 10%, 15% and 20% of olive oil were substituted for lard, respectively. Pressed ham manufactured with olive oil was vacuum packaged and stored for 1, 7, 14, 21 and 28 days at $4^{\circ}C$. Samples were analyzed for shear force value, sensory properties, TBARS values and fatty acid composition. Shear force values increased significantly during storage for all treatments. No remarkable differences were found in sensory properties (color, flavor, texture, and acceptability) between the control and olive oil treated hams, and there was no clear change with increased storage time. There was no significant difference in TBARS values between the control and olive oil treated hams. The TBARS values increased significantly during storage for all treatments. With regard to changes in fatty acid composition, the contents of C14:0-C20:4 were decreased significantly by the addition of olive oil. The saturated fatty acid and polyunsaturated fatty acid contents of the control were significantly higher than the olive oil treated hams. Higher levels of added olive oil resulted in significantly higher monounsaturated fatty acid contents. Based on these findings, we conclude that the sensory properties and lipid oxidation (TBARS) of manufactured pressed hams are not affected by olive oil addition. These results also indicate that high-quality pressed ham can be manufactured with increased monounsaturated fatty acid content.

Background: Recently, the number of people interested in health in South Korea has increased, and the rate of dietarysupplement use is rising. Researchers have hypothesized that the rate of practicing healthy habits is higheramong those who use dietary supplements than those who do not. Therefore, this study aimed to discover the associationbetween taking dietary supplements and practicing various healthy habits in the Korean, adult population. Methods: The sample included 15,789 adults over 19 years old who participated in the fifth Korea National Healthand Nutrition Examination Survey. The user group was defined as those taking dietary supplements for more than2 weeks during the previous year or once during the past month. Measures for the seven healthy habits were basedon those included in the Alameda study and were analyzed accounting for the complex sampling design. Results: The rate of taking dietary supplements was significantly higher in women, middle aged participants, urbanresidents, those with a higher income, those with a higher education level, and nonsmokers as well as amongwomen with a moderate subjective health status, women who limited their alcohol content, and women with dyslipidemia. In the adjusted analysis, the rate of performing three of the ‘Alameda 7’ habits—eating breakfast regularly,restricting snacking, and limiting drinking—was higher in the female dietary supplement user group than in theother groups. Women practiced more healthy habits and had a higher dietary supplement intake rate than men. Conclusion: We found that taking dietary supplements in Korean adults is highly associated with demographic andsocial factors. Taking dietary supplements had a relationship with dietary habits, and there was no significant associationbetween dietary supplement and other healthy habits. Thus in the health clinic, we suggest that taking dietarysupplements complements a patient’s healthy habits, with the exception of dietary habits, for health promotion.

본 연구는 문제풀이 중심으로 운영되는 고등학교 생명과학 수업에서 교육매체의 일종인 교실응답시스템(CRS)의 활용 가능성을 알아보고자 하였다. 교수·학습 전략으로 CRS 활용반(34명)은 학생들이 CRS 단말기로 응답한 결과를 교사가 즉시 파악하고 개인별 응답 이유를 질문한 후 피드백을 하였다. 비교반(34명)에서는 CRS를 사용하지 않았으며 학생들에게 일괄적인 피드백을 하였다. 연구 결과, CRS 활용이 학생들로 하여금 수업 활동에 흥미와 집중력을 높여주는 것으로 인식되었다. 그러나 학업 성취도의 향상에 있어서 CRS 활용반과 비교반 사이에 유의한 차이는 없었다. 다만 성적 수준에 따라 그룹을 나누었을 때, 중위그룹에서는 CRS 활용반과 비교반 사이에 학업 성취도의 향상에 유의한 차이를 보였다. 진단평가 및 형성평가에서 CRS 활용의 효과를 높이기 위해서는 다양한 수준의 문제들을 사전에 개발하고, 학생들의 응답 이유를 정확히 파악하여 더욱 많은 학생들에게 개인별 맞춤형 피드백을 할 수 있는 교수 전략의 개발이 필요함을 제안한다. The purpose of this study was to examine the potential of the use of Classroom Response System (CRS), a kind of new ICT medium, in the quiz problem-solving oriented high school life science class. To find usefulness of CRS as a teaching and learning strategy, CRS group (n=34) sent prompt individual answers to the teachers` questions using CRS terminal (Clicker), and then the teacher asked additional individual reasons and gave personalized feedbacks. In the control group (n=35), CRS was not used while the teacher asked overall questions and gave feedback in an undifferentiated way. As a result, using CRS increased students` interest and concentration during class, but there were no significant differences in study achievement between the two groups. However, there were significant differences between the medium-level groups when the two groups were divided into smaller ones based on their pre-scores. We suggest that, for the effective CRS for diagnostic and formative assessment, teachers should develop the teaching and learning strategy that can produce appropriate questions with various levels in advance, investigate exact reasons for students` answers, and give customized feedback by individual as much as possible.
