The purpose of this study was to evaluate the relationship between the diversity of food intake and nutrient intake among Korean college students participating in a nutrition education class via the internet. The subjects were 796 college students throughout South Korea (278 males, 518 females). A 3 days dietary recall survey was conducted and results were analyzed using the Computer-aided Nutritional Analysis Program. Dietary variety was assessed by DDS (dietary diversity score), MBS (meal balance score), and DVS (dietary variety score). Dietary quality was assessed by NAR (nutrient adequacy ratio), and MAR (mean adequacy ratio). As the DDS, MBS and DVS increased, the NAR and MAR improved. The subjects with a DDS of above 4 or a MBS of above 10 or a DVS of above 11 met two-thirds of the Korean recommended dietary allowance for most nutrients. The DDS, MBS and DVS correlated positively and significantly with the NAR and MAR. Associations between the NAR and high levels of DVS were more positive than those between the NAR and the DDS. Based on these results, the food intake of these subjects was not adequate. Specially, the dietary intake of calcium and iron were not adequate. Therefore, dietary guidelines should be made considering nutritional characteristics so as to improve the intake from all of the major food groups and provide a variety of foods in their diets.

Century-old nutrition and health concepts can be revived and applied in the modern age in the forms of newly developed menus, recipes, and lifestyle education. Current medical nutrition therapy concepts were first described in the Chosun Dynasty (1392-1897) in Korea based on the philosophy that food and medicine originate from the same source, which is known as 'food as medicine'. Recognizing the importance of culture, tradition, local diet, and lifestyle on health and medical nutrition therapy, we tried to rediscover traditional Korean approaches towards food consumption and nutrition through systematic review of the literature and developed contemporary menus accordingly. The medical nutrition therapy prescriptions described in 'Shikryochanyo' (1460) by the Chosun Dynasty's royal physician Soonyi Jeao cover 45 different diseases. In this project, we developed contemporary menus for those disease models that are most prevalent in modern society. Menus developed with foods that are readily available today were evaluated for their nutritional content and adequacy using a computer-aided nutritional analysis program (CAN pro 3.0, developed by the Korean Nutrition Society for comparison with RDA for Koreans). Therefore, century-old nutrition and health concepts can be revived and applied in modern society as newly developed menus recipes and lifestyle education.

We study an (n+3)($n\;{\geq}\;7-dimensional$ real submanifold of a (4m+3)-unit sphere $S^{4m+3}$ with Sasakian 3-structure induced from the canonical quaternionic $K\"{a}hler$ structure of quaternionic (m+1)-number space $Q^{m+1}$, and especially determine contact three CR-submanifolds with (p-1) contact three CR-dimension under the equality conditions given in (4.1), where p = 4m - n denotes the codimension of the submanifold. Also we provide necessary conditions concerning sectional curvature in order that a compact contact three CR-submanifold of (p-1) contact three CR-dimension in $S^{4m+3}$ is the model space $S^{4n_1+3}(r_1){\times}S^{4n_2+3}(r_2)$ for some portion $(n_1,\;n_2)$ of (n-3)/4 and some $r_1,\;r_2$ with $r^{2}_{1}+r^{2}_{2}=1$.

The hybrid teaching approach of "MOOC + SPOC + Flipped Classroom" overcomes the constraints of time and space that are typically associated with traditional teaching methods, thus compensating for the shortcomings of traditional approaches. These changes in education are driven by the "Internet+" wave and the growing popularity of online teaching. The "MOOC + SPOC + Flipped Classroom" hybrid teaching mode can successfully compensate for the drawbacks of traditional teaching methods, thereby overcoming their restrictions. By defining relevant concepts, one can distill the key characteristics of the "MOOC + SPOC + Flipped Classroom" hybrid teaching mode. Formative assessment was employed to thoroughly evaluate the effectiveness of this teaching approach. By leveraging the advantages of massive open online course (MOOC), small private online course (SPOC), and flipped classroom, the "MOOC +SPOC + Flipped Classroom" teaching mode incorporates real-time student assessment through peer evaluation, computer-aided evaluation, and teacher evaluation. This mode promotes the simultaneous development of theoretical knowledge and practical skills, helping students to establish strong foundations while fostering their practical abilities. While the traditional teaching method remains fruitful, the convenience of today's network allows the teaching profession to continually evolve. The traditional teaching mode heavily relies on teachers, making it impossible to conduct lessons without them. However, the development of MOOC enables students to seek knowledge online from their preferred teachers, rather than solely relying on their assigned instructors.

Tangram game consists of seven pieces of polygons such as triangle, square, and parallelogram. Typical methods of image processing for object recognition may suffer from the existence of side thickness and shadow of the puzzle pieces that are dependent on the pose of 3D-shaped puzzle pieces and the direction of light sources. In this paper, we propose an image processing method that recognizes simple convex polygon-shaped objects irrespective of thickness and pose of puzzle objects. Our key algorithm to remove the thick side of piece of puzzle objects is based on morphological operations followed by logical operations with edge image and background image. By using the proposed object recognition method, we are able to implement a stable tangram game applications designed for tablet computers with front camera. As the experimental results, recognition rate is about 86 percent and recognition time is about 1ms on average. It shows the proposed algorithm is fast and accurate to recognize tangram blocks.

Using an arterial pressure-volume (APV) model, we performed an analysis of the conventional blood pressure estimation method using an oscillometric sphygmomanometer with computer simulation. Traditionally, the maximum amplitude algorithm (MAA) has been applied to the oscillation waveforms of the APV model to obtain the mean arterial pressure and the characteristic ratio. The estimation of mean arterial pressure and characteristic ratio was significantly affected by the shape of the blood pressure waveforms and the cutoff frequency of high-pass filter (HPF) circuitry. Experimental errors result from these effects when estimating blood pressure. To determine an algorithm independent of the influence of waveform shapes and parameters of HPF, the volume oscillation of the APV model and the phase shift of the oscillation with fast Fourier transform (FFT) were tested while increasing the cuff pressure from 1 mmHg to 200 mmHg (1 mmHg/s). The phase shift between ranges of volume oscillation was then only observed between the systolic and the diastolic blood pressures. The same results were obtained from simulations performed on two different arterial blood pressure waveforms and one hyperthermia waveform.

This study is to understand the situations of special education classroom layout, find differences according to school levels and summarize the findings in order to build up the indicators for special classroom layout. As for elementary school level, special classrooms are using multi-purposes desk or group desk for diverse activities such as basic learning and formation of basic life practice. The most frequent type in classroom layout is Type E which is for diverse coner-learning and play activities and the next is Type C which secures activity space. Because security of dynamic activity which most teachers find problematic is important, it needs more research to secure dynamic activity space within classroom. As for middle school level, the most frequent type in classroom layout is Type B which is equiped for computer aided learning and the next is Type C which secures activity space. Research for systematic layout of activity space is needed in order to secure the spaces of dynamic activity and basic job training. As for high school levels, mostly Type B which emphasizes computer activities is adopted and next is Type F which is capable for job training. The survey about the size of special education classroom proves that most teachers want one and half size classroom which in not such a large classroom. It is expected that more systematic research of special classroom layout according to school levels may reach for rational space layout.

The aim of this study was to compare the dietary patterns and behaviors of university students according to their type of residence. The subjects consisted of two thousand two hundred fifty students from Wonkwang University. They were divided into three groups : those who live in their family homes (393 men, 392 women) ; those who live in university dormitories (371 men, 401 women) : and those who live in houses with cooking facilities (345 men, 348 women). This cross-sectional survey was conducted using a self-administered questionnaire. The nutrient intake data collected from a three-day recall were analyzed using the Computer Aided Nutritional Analysis Program and the diet quality was estimated using the Nutrient Adequacy Ratio, Mean Adequacy Ratio and Index of Nutritional Quality. The results showed that the mean daily intakes of calcium were lower than the Korean Recommended Daily Allowance (RDA) in all groups. There was a significant difference in the nutrient intake, dietary quality and dietary behaviors of the three groups. The nutrients intake and dietary quality of the men were poorer than those of the women in all three groups. The subjects living in dormitories and houses with cooking facilities seemed to have lower levels of nutrient intake and dietary quality. However, the concern about nutrition and interest in health information was higher among those living in dormitories and houses with cooking facilities than among those living in their family homes. Male students living in houses with cooking facilities had more dietary problems than students living in their family homes or in dormitories possibly because they might have had a lower ability in meal management. These results suggest that the type of residence affects the nutrient intake levels, and dietary quality of university students in Iksan. Nutritional education is essential if university students are to practice optimal nutritional habits, including the eating of well-balanced diets and selecting of foods of high quality. Therefore, nutritional education for university students is needed so as to improve their health and a nutritional education program should be developed to meet the various needs of these students.
