Freeze-dried Kimchi powder has to be first produced to make Kimchi noodle. Two days, ten days, fifteen days and twenty-five days fermented Kimchi were analyzed respectively to obtain adequate material for freeze-dried Kimchi. Fourteen days' fermented Kimchi with pH 4.0∼4.7 and 0.5∼0.8% acidity was chosen for material for freeze-dried Kimchi, Fourteen days fermented Kimchi was first freeze-dried and powdered. Sensory evaluation was done to decide that 4% addition of the powdered material was optimal. The mixture of Kimchi noodle was analyzed into two perspectives; noodle and Kimchi. The analyzed factors of the mixture was a texture of noodle, color level, Kimchi flavor and its spiciness. The texture of noodle are nutty taste, softness, viscidity and oil flavor. Heavy oil flavor and nutty tasty decreased against the increase of Kimchi powder. Six percent addition of material showed a definite change to the mixture. More than six percent addition destroyed the texture of noodle into near crumbles. Four percent addition of material showed almost same as ordinary noodle texture. Therefore four percent addition of freeze-dried Kimchi was chosen optimal through sensory evaluation.

In the process of development the e-learning course at Cyber University, one important factor to be considered for the effective e-learning contents is the User Interface(UI) of the e-Learning content platform. The User Interface is important because the well-designed UI can help students to perform effectively and easily learning activities. Despite the importance of the usability, few attempts have been carried out to design the e-learning contents UI from the usability perspectives. Thus, the purpose of this study is to explore the usability design elements for the e-learning contents UI. For this purpose, a usability evaluation study on the e-learning contents UI of a cyber university at Seoul was conducted. Implications for the improvement of the current e-Learning contents UI was presented.

A plate type supporting structure of a tube bundle in axial flow generates a certain band of a high frequency periodic excitation of a vortex shedding and/or a flow separation due to sharp edge of the plate thickness and a severe pressure drop due to a cross-sectional area of the supports. With a design consideration of the low vibration and a small flow resistance, the analysis method is uniquely confined to an experimental approach because a complex geometry of a cylindrical tube bundle and/or physical phenomena related to the fluid-structure interaction of tube bundle in a flow impede a theoretical or a numerical approach. A 5x5 cylindrical tube bundle with 5 supports which were discretely located along the bundle's axis was tested in the FIVPET hydraulic test loop for a design evaluation and an analysis perspectives. A high frequency flow-induced vibration of the supporting structures of the cylindrical tube bundle was measured at a outer surface of a supporting structure through a transparent flow housing by the laser dopper vibrometer. Pressure drop in-between three measurement distances was measured by the differential pressure transmitter. High frequency vibration and pressure drop fairly depends on the geometric design of supporting structure. So, these two parameters would be used as a qualitative design variables for design evaluation and analysis.

Soybean is one of the most important sources of protein and oil in the world. Recently, emphasis has been laid on the chemical composition of soybean seeds for the processing soybean foods. Improvement of soybean components has been expected to improve food-processing quality for the processed soybean products such as soymilk and various edible ingredients as well as fur the traditional soyfoods. In Korea, soybean breeding research programmes have been focused on the quality of the products derived from soybean with yield stability, and some new modified soybean varieties haying good food-processing quality were developed recently. So the efforts of establishing standard and standardization of products in soybean are important. Three main categories should be considered in view of soybean seed quality; the marketing value such as grain size, shape, and appearance; the eating and processing value such as dehulled ratio, water absorption rate, and benny flavor; the nutritional value such as protein, lipid, and carbohydrate contents. And the new frontiers in research are looking at the functional nutrients in soybeans and how to improve them. In case marketing value, mainly the appearance is evaluated, therefore, each country has an application of standard related to quality. Each determination of standard class, heat-damaged kernels, splits, and soybeans of other colors is made on the basis of the grain when free from foreign materials. But processing value and nutritional value for standardization were not studied in detail till now. In addition, soybean has potential roles in the prevention and treatment of chronic diseases, most notably cancer, osteoporosis, and heart disease. The functional nutrients include a protease inhibitor, phytic acid, saponins, and isoflavones, etc.. It is believed that standardization of soybean quality should perform to overcome the difficulties, relatively high price of domestic soybean products has weakened the competitive power, in the market related to WTO. So, we should focus on further research into the evaluation and establishment of quality-standard in soybean.

Caldera is a large depression commonly formed by collapse of the ground following explosive eruption of a large body of stored magma. On earth, calderas and caldera complexes range in size from kilometers to tens of kilometers. Historical eruptions associated with caldera collapse have led to huge fatalities in Indonesia as well as left global impacts. This study presents case study on calderas in Indonesia which resembles to Mount Baekdu located at the border of China and North Korea; in the perspectives of similar characteristics, principal hazard, recent symptom of volcanic activity and the threat if eruption occurs in the near future. Calculation by using weighted evaluation matrix for Mount Krakatau, Mount Tambora, Mount Ijen, Tengger Caldera, Mount Rinjani and Ranau Caldera were taken for the selection of a site for future case study.

Purpose: The purpose of this study was to investigate the academic achievements, satisfaction and educational demands of nursing students at a college of nursing. Methods: The study subjects consisted of 134 senior nursing students who completed their clinical practicums. The students were asked to complete the evaluation survey for the curriculum. The evaluation survey for the curriculum consisted of three parts: 1) academic achievements of educational objectives, care of subjects, and skills; 2) satisfaction with the curriculum, clinical practice environment, and educational environment; 3) demands on the curriculum and clinical practicum. Results: The mean scores on the achievement levels of educational objectives, care of subjects and skills of the students were $3.68{\pm}0.53$, $3.69{\pm}0.59$, and $3.77{\pm}0.56$, respectively. The low rated domains were 'understanding and delivering culturally competent nursing' and 'competence in fundamental nursing skills' in their levels of achievements. Overall, students were satisfied with the nursing curriculum and educational environment. However, their satisfaction scores for the hours and arrangements of the clinical practicum, and the ratios and arrangements of lectures and clinical practicum were relatively low. Conclusion: The findings of this study are important to redesign nursing curriculum in order to prepare graduates for rapidly changing health care environments. We need to try various strategies to improve the clinical competencies of students by designing a curriculum based on social change and student needs.

In this paper, we proposes a comprehensive analysis of the characteristics, selection procedures, and management perspectives of each university's financial support project, and derivation of a plan to integrate the information system of the university's financial support project. To this end, we analyze the current status of business operations before and after restructuring university financial support projects, and identified the characteristics, commonalities, and differences of each project. Individual projects are promoted segmentally, evaluation indicators and evaluation methods are different for each business, standardization is difficult, and in the absence of integrated governance, sympathy and will of the system integration of the government and the managing agency cannot be found. In order to integrate the system, the business management process must be integrated and standardized, and the system equipment such as budget category adjustment must be complemented, and a stable budget for system integration must be secured.
