This study was conducted to determine the mixing conditions for Hibiscus syriacus L. chocolate depending on different addition ratios of Hibiscus syriacus L. and examine functionality in order to use Hibiscus syriacus L., which has excellent functionality and symbolizes Korea. To accomplish this, Hibiscus syriacus L. chocolate was manufactured by adding 0%, 2.5, 5, 7.5, and 10% of Hibiscus syriacus L. powder from the ‘Samchulli’ (Hibiscus syriacus ‘Samchulli’, which has reddish pink flower with red eye spot: SKK 14-2-72) variety to a coverture of white chocolate after which the antioxidant activity and quality characteristics were analyzed. As the amount of Hibiscus syriacus L. powder added to the chocolate increased, the chocolate color became darker, the pH decreased, and the sugar content and hardness increased. As a result of the sensory evaluation, the degree of preference increased as the amount of added Hibiscus syriacus L. powder increased to 7.5%. The degree of preference for color and flavor was the highest in the 5% added group, but the overall preference was 7.5% added chocolate. These findings demonstrate that adding Hibiscus syriacus L. powder to chocolate can increase chocolate functionality and preference and that there is a high possibility of Hibiscus syriacus L. chocolate development.

Metabolic syndrome is a risk factor for cardiovascular and type 2 diabetes. This study was conducted to examine the relevance between nutrition intake, meal quality, and high-sensitivity C-reactive protein in Koreans with metabolic syndrome. The 2,536 subjects, aged 19~64, who participated in 2015 National Nutrition Survey were included in this study. The 24-hour recall method was employed to analyze nutrition intake and dietary quality. Subjects were grouped into either the non-metabolic syndrome group (n=1,938) or the metabolic syndrome group (n=598). Total males and females were divided into 3 groups according to the high-sensitivity C-reactive protein (hs-CRP) level to study its relationship to metabolic syndrome and its components, including odds ratio (OR) and confidence interval (CI). Results showed the homeostasis model assessment of insulin resistance (HOMA-IR) value was higher in the metabolic syndrome group (3.37) than non-metabolic syndrome group (1.57) (p<0.001). In the Index of Nutrition Quality, males in the non-metabolic syndrome group showed higher niacin (p<0.05) than males in metabolic syndrome group. Females in the non-metabolic syndrome group had higher vitamin B1 (p<0.01), vitamin B2 (p<0.001), niacin (p<0.05), calcium (p<0.001), and phosphate (p<0.01). Female in the high hs-CRP group showed high OR in blood glucose component (OR 2.488, 95% CI: 1.269~4.879) and metabolic syndrome risk (OR 2.856, 95% CI: 1.292~6.314). Females in the middle hs-CRP group had high triglycerides component (OR 2.956, 95% CI: 1.920~4.551), compared to the low hs-CRP group. The study showed females with higher hs-CRP had a higher risk of metabolic syndrome.

This study aimed to develop and evaluate a sugars intake reduction program (SIRP) that was designed to increase the knowledge, attitude, and skills of Korean children aged 5 years regarding sugars intake reduction. A total of 101 children aged 5~6 years from 6 preschools participated in SIRP. SIRP consisted of 4 sessions including 10 activities (e.g., story-telling, arts, experiment, checking nutrition facts, pledge), delivered to children at preschools by nutritionists over a one-month period. Three letters were sent to parents throughout the program to inform them of the children’s activities at the preschools and to provide additional information on reducing children’s sugars intake. A total of 90 children completed the program; 83 parents of these children completed the SIRP evaluation survey. The children’s sugars intake reduction score was significantly increased after attending SIRP. Teachers (n=6) who participated in this program agreed to improve their students’ attitudes on reducing sugars intake and to decrease students’ behaviors related to sugars intake. Parents agreed to improve their children’s attitude on reducing sugars intake and to decrease children’s behaviors related to sugars intake. The outcome showed SIRP improved participants’ attitudes towards sugars reduction and increased the skills to reduce the sugars intake of children aged 5~6 years. Future studies should examine whether SIRP reduces actual sugars intake among children.

The purpose of this study was to evaluate the nutritional knowledge and dietary behaviors of middle school students according to their mother’s employment status. Of all 453 subjects, 52.1% were boys, and 67.5% of the mothers were employed. The total score of nutritional knowledge was 8.0 out of 10 for students with a non-working mom and 7.7 for those with a working mom, showing no significant difference. Among the 20 nutritional knowledge questions, correct answer rates for “lots of fruits may be eaten because of not gaining weight” (72.6% vs. 81.6%, p<0.05) and “eating raw carrots is better than eating fried ones with oil” (34.6% vs. 44.9%, p<0.05) were significantly higher in students with a working mom. The regularity of meals showed a significant difference according to the mother’s employment, indicating that responses of “very regular” (62.4% vs. 72.1%) were high among students with a non-working mom and responses of “skipping breakfast” (31.4% vs. 19.7%) were higher in students with a working mom (p<0.05). The number of snacks a day was also significantly different according to the mother’s employment, showing that 12.8% of the students with a working mom and only 3.4% of them with a non-working mom did not eat snacks at all (p<0.05). These results reveal no significant difference in middle school students’ nutritional knowledge according to their mother’s employment status; however, the students whose mother had a job were more likely to have more undesirable dietary behaviors such as irregular meals and snacking.

This study aimed to develop unique, local “food tourism” products by finding specialized items that combine tourist attractions, such as folklore or hot springs. Traditional ingredients were analyzed with ancient texts for the methods of research. A brand image was made possible utilizing hot spring lore and other regional stories. The tofu products were produced using local specialty beans. Products, such as tofu residue cake and willow bean tea, were made with the tofu residue. After the products were completed, the sensory test began at the local tourist attraction. Asan City’s food tourism product willow tofu was made with beans that were given as compensation for building the Onyang temporary palace according to the Annals of the Joseon Dynasty and the willow tree that appears in Sunshin Lee’s anecdotes. After the preference test between normal tofu and willow-extract tofu was conducted to measure the product potential of willow tofu, among the sample extracts, 0.04% of the willow extract showed a significant preference. The hot spring tofu-residue cake was baked using tofu residue and vegetable olive oil to substitute for animal oil, such as butter, or margarine. After the sensory test targeting the adults was conducted, both products displayed significant product potential with average scores above 5.0. Willow tree bark, which hasantioxidation and anti-inflammatory effects without a bitter taste or strong smell, was proven to bean appropriate ingredient for leached tea. The nutty flavor of leached tea was enhanced by roasted green kernel black beans and willow tree bark. The sensory test showed that the leached tea and tofu received a high preference rating on both color and flavor.

반려동물산업은 지속적으로 성장하였으며, 2020년에는 반려동물 관련 시장규모가 5조 8,000억 원으로 성장할 것으로 예상된다. 하지만 반려동물 산업이 지속적으로 성장한 것에 비해, 반려동물 문화의 수준은 성숙하지 못하다. 반면에 해외의 반려동물 시장은 우리 나라보다 크고, 반려동물 문화 또한 성숙한 문화가 자리 잡고 있다. 그래서 해외 반려동물 문화 관련 현황 파악을 통해서 국내 반려동물 문화 발전을 위해 제안할 수 있는 것을 알아 보고자 총설논문을 작성하였다. KISS, DBpia, RISS, 원광대학교 중앙도서관에서 자료를 검색하였으며 자료들을 크게 국･내외 반려동물산업, 국･내외 반려동물문화, 국･내외 반려 동물 관련법과 정책으로 분류하였다. 연구결과, 우리나라의 올바른 반려동물 문화를 정착 시키기 위해서는 개선되어야 하는 점이 많았으며, 해외의 반려동물 문화를 통해 발전될 수 있다는 점이 많다고 판단된다.

‘반려동물 가구 1천만 시대’, ‘4가구 중 1가구가 반려동물 가구’. 이제 반려동물과 함께 사는 사람을 보는 것이 흔한 일이 되었다. 반려동물 가구가 전폭적으로 증가하고 있는 추세임에도 불구하고 반려문화의 발전 속도가 현저히 뒤쳐져 위와 같이 반려견의 공공장소 이용에 대한 반려인과 비반려인 간의 갈등이 심화되고 있다. 때문에 반려인과 비반려인간의 갈등을 해소하여야 할 필요성을 느껴 이를 위해 국내 반려견 공공장소 이용에 대한 비반려인의 인식을 조사하고자 하였다. 본 논문은 설문조사를 통해 진행되었으며, 공공장소 중 반려인과 비반려인의 접촉이 가장 빈번한 공원, 인도, 내부 공공장소, 공동주택, 대 중교통을 선정하여 각 장소에 따른 인식을 조사하였다. 설문조사 결과 각 장소마다 비반려인이 반려인과 반려견에 대해 가지고 있는 인식과 요구사항이 다르다는 것을 알 수 있었다. 예상 외로 반려견 자체에 대하여 부정적으로 보는 사람보다 긍정적으로 보는 사람이 다수였다. 반려견의 공공장소 이용을 부정적으로 보는 사람 중에서는 반려견에 대한 인식부족으로 인한 편견을 이유로 드는 한편 반려인의 펫티켓 부족, 반려견 관리 미흡을 이유로 들기도 했다. 이를 개선하기 위해 각 지방자치단체에 동물보호과가 신설 및 증설을 통해 처벌뿐만 아니라 목줄 미착용과 같은 동물보호법 위법행위에 대한 감시 감독 또한 강화해야 한다. 더불어 국가적 차원에서 국민을 대상으로 인간과 동물의 공존을 위한 교육이 시행되어야 한다. 동시에 반려인을 대상으로 한 올바른 펫티켓을 비롯한 반려동물 관리에 대한 교육이 필요하다.

Purpose: This study aimed to evaluate differences in nursing performance of nursing college students following simulator training or video-based training for patients with respiratory distress. Methods: The study used a two-group post-intervention design. The simulator group was trained using a high-fidelity simulator and the video group with a best practices video. Nursing ability was evaluated by video recording participants during a dyspnea simulation exercise. The collected data was analyzed with a t-test using SPSS 21. Results: The simulator group showed lower scores than the video group in the preparation (t = -4.60, p < .001) and nursing intervention (t = -2.41, p = .033) categories. Conclusion: Video training is effective for simulation education in cases of dyspnea.

This study investigated a bio-tensegrity structural system that combines the characteristics of a general tensegrity structural system with a biological system. The final research objective is to accomplish a changeability for the structural system as like the movement of the natural bio-system. In the study, we present a shape finding procedure for the two stage bio-tensegrity system model inspired by the movement pattern of animal backbone. The proposed system is allowing a dynamic movement by introducing the concept of “saddle” for the variable bio-tensegrity structure. Several shape finding analysis example and results are presented and shows a efficient validation and suitability.
