The knowledge resources take a role in promoting the sustainable growth of organization. Therefore, it is important for the members of organization to acquire knowledge consistently so that the company can continue to grow. Knowledge service is the field that provides information and infrastructure which enable the members of organization to acquire new knowledge. As we recognized the importance of knowledge services, we analyzed the level of knowledge service management and development through the impact of knowledge quality on user capabilities. First, the matrix of knowledge patterns was presented based on the type of information and the level of customer interaction. According to patterns, the knowledge service was classified into three types of information providing, information analysis, and infrastructure, and then the results of structural model analysis were presented for each type. It found that the impact of knowledge service quality on user competence was different according to the type of service. The results suggested new indicators for measuring the performance of knowledge services, and provided information for reconstructing services based on the user considering the integrated operation of knowledge service and organizational designing knowledge service.

While estuarine dams can develop freshwater resources and block the salt intrusion, they can result in increased sediment deposition in the estuary. The mechanism of increased sediment deposition in an estuary with an estuary dam is not well understood. To fill this knowledge gap, 7 ADCP measurements of flow and suspended sediment concentration (SSC) were collected along-channel in an estuary with an estuarine dam over a neap-spring cycle. Flow and SSC were used to calculate the sediment flux and sediment flux gradients. The results indicated that the cumulative sediment fluxes at all stations were directed landward. The along-channel sediment flux gradient was negative, which indicated deposition along the channel. The landward mean-flow fluxes were dominant in the deep portion of the channel near the estuary mouth, whereas landward correlation fluxes were dominant in the shallow portion of the channel near the estuarine dam. The tides were the dominant forcing driving the sediment fluxes throughout the estuary.

Nutrition education in elementary school is confronted with the present problem, as a legal basis about obligation of nutrition education in school was clarified. Moreover, it's also important for providing evidence based scientific resources to make a study of evaluating the education effectiveness. Most studies of the nutrition education effectiveness have evaluated the changing dietary attitude and nutritional knowledge score before and after the nutrition education, and suggested the effectiveness of intervention as changing between pre- and post-treatment. Nutrition education, however, purposing long-term changes, follow-up evaluation process about the learned attitude and knowledge of nutrition education were requested. For these reasons, this study attempted to fulfilled standardized nutrition education program which use "Na Story and Food World" and "Na Story for Me", a textbook for the 1st-3rd grade and 4th-6th grade designed by KFDA, and analyzed the changes about the effectiveness of nutrition education happened over a period of time. In this study, each student was assessed their dietary attitude and nutritional knowledge by four periods, before the education, right after the education, after 3 months, and after 6 months. As a result, an average score of nutritional knowledge before the education, $70.08{\pm}17.91$, were changed significantly higher right after the education to $85.69{\pm}15.05$ (p < 0.001), but it lowered to $84{\pm}15.56$ after 3 month. After the nutrition education, students in all grades had positive dietary attitude to Na reduction (p < 0.001). However, the healthy eating attitude about Na reduction had been unable to maintain after 3 and 6 months. Therefore, the systematic reeducated program in elementary school was positively necessary to reinforce children's learning and cognitive skills to maintain healthy eating knowledge and attitude toward Na reduction.

The hospital school is an organization designed to encourage long-term health-impaired students to receive treatment and education at the same time. There are 33 hospital schools in Korea. However, the management of hospital schools varies greatly depending on the amount of resources and support they possess, and especially the lack of manpower and quality improvement of education programs were found to be the biggest problems. This study aims to discuss the case of Hospital School in Yeungnam University Hospital (YUH), which successfully overcame internal resource limitations while solving existing hospital schools through networking and open innovation with external organizations. In particular, through cooperation with students of Herewego, volunteering club in Yeungnam University business school(YUBS), we increased the social interest of hospital school by creating a special program with financial support of Daegu city. They created customized education service programs for hospital schools that reflect their major-business management. The cooperativ e case of YUH's Hospital School and YUBS's Volunteering Club of Herewego showed that the cooperation is not only about volunteering service but also the open innovation, introduced as a platform to expand the company's source of product development. We think that this is a case of value creation through exchange of knowledge. It could have many implications for solving the problem of hospital school.

While organizational learning (OL) is vital for ventures to build knowledge bases necessary for successful innovation, less attention has been paid to how learning organizations leverage it for performance improvement. We investigate entrepreneurial orientation's (EO) role in performance-by-learning mechanisms underpinning ventures' innovative initiatives, adopting dyadic performance indicators: technological competitiveness and business performance. Analyzing 218 Korean ventures, our study shows that firms valuing OL, characterized by acquisitive and experimental learning, exhibit high EO, facilitating productive use of knowledge-based resources and enhancing performance. Importantly, EO fully mediates the performance implications of OL. Our findings suggest that a comprehensive learning approach for knowledge acquisition and experimentation provides ventures, often facing smallness and newness liabilities, with a fertile entrepreneurial ground for increased innovation returns.

The purpose of this study was to investigate the effects of nutrition education on nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea. The subjects were 64 Chinese college students in Korea (educated group, 32 students vs. non-educated group, 32 students). Educated group was lessoned as group and/or individual. Nutrition education program consisted of four lessons (40min/lesson), '6 major nutrients & function (group lesson)', '6 food group and sources (group lesson)', 'personalized daily needed energy and food exchange units using Food Exchange System (individual lesson)', and 'smart choice of snacks and eating-out foods (group lesson)'. We examined the differences between educated group and non-educated group in nutrition knowledge, dietary attitudes and nutrients intake. After education, there were positive improvements on nutrition knowledge: 'function and foods of 6 nutrients', on dietary attitudes: 'type of breakfast' in educated group. In the evaluation of nutrient intakes according to Dietary Reference Intakes for Korean (KDRI), there were positive improvements on intake levels of riboflavin, fiber, vitamin B6, vitamin C, folate, Ca and K in the educated group. In the index of nutrition quality (INQ), nutrition adequacy ratio (NAR) and mean nutrition adequacy ratio (MAR) were significantly increased in the educated group. In conclusion, it is possible to improve nutrition knowledge, dietary attitude and dietary intake of Chinese college students in Korea through the nutrition education focused on personalized daily needed energy and food exchange units.

The purpose of this study was to develop a nutrition education program for dietary salt reduction using various nutrition education materials. The effect of a 5-week nutrition education program on salty taste assessment, nutrition knowledge, salt attitude for a high-salt diet, salt content in food, and individual satisfaction with the salt concentration of meals during the education period was evaluated. Nutrition education materials included two animations, a pamphlet, panels, and a website, as well as other training resources. Subjects participating in this study were 335 employees (164 male, 171 female) at 15 foodservice operations in Daegu. Preference for higher levels of salty taste and food containing higher amounts of salt were lowered. Knowledge regarding the necessity for dietary salt reduction was higher (p < 0.001) than before nutrition education, and salt content in a meal was reduced. As the program progressed, average salt concentrations of soups were significantly lowered (p < 0.05), and there was greater satisfaction with the lower concentration (p < 0.001). This was a positive indication of the program's success. In addition, it was found that subjects who participated in the program several times have changed their preference to lower levels of salty taste and have increased their nutrition knowledge (p < 0.05, p < 0.001). Thus, the positive effect of this 5-week nutrition education program developed for, and applied to, foodservice employees, concerning dietary salt reduction was confirmed.

Even though various geological attractions are distributed domestically, the geological attractions are rarely utilized as field course site. The purpose of this study is to make Seonangbawi area as the field course site after geological investigations are carried out in detail. Seonangbawi is located about 1km southeast from Songjiho beach in Gangwon-do. Seonangbawi area is simply composed of Cretaceous Seokcho granite with the overlay of Quaternary alluvium. Geological field course in the Seonangbawi area will be useful to the student and citizen for developing the knowledge of geological phenomena, such as the formation of granite and minerals, and weathering process. In addition, the student and citizen can develop the knowledge of the geological structures, such as joint (N50E/80NW, N40W/84SW), fault (N42W/83SW), foliation (N32E/54SE), and dyke (N35E/40SE, N26W/63SW), and geographical features, such as tor, taforni, groove, and gnamma in the field. Accordingly, the Seonangbawi area is the best place to learn various geological and geographical phenomena and to discuss the origin of Seonangbawi with limited space.

This study examines the impact of consumer knowledge and familiarity with private label brands (PLBs) on perceptions and preferences toward PLBs and patronage intentions; in addition, it examines the incremental effects of a department store image over consumer knowledge and familiarity with perceptions, preferences, and patronage intentions. This study focused on midscale department store PLBs of apparel products and middle age consumers between the ages of 30 and 50 who are the main consumer group of private label brands of apparel products. A structured questionnaire was developed and data were collected from a convenience sample of 257 female consumers between the ages of 35 and 54, living in the Southeastern United States. A factor analysis identified the dimensions of department store image constructs; in addition, a hierarchical regression and multiple regression analyses examined the hypotheses. Consumer knowledge and familiarity with PLBs at department stores is recognized as a major determinant to shape consumer perceptions of and preferences for the PLBs as well as patronage intentions. The present study reveals the significant incremental effect of a store image on consumer preferences, perceptions, and patronage intentions beyond that explained by consumer knowledge and familiarity about PLBs. The study reveals that, among four store image constructs, the store atmosphere and store service factors had significant positive effects on consumer perceptions of PLBs. Store service and atmospheric aspects also affect consumer patronage intentions toward PLBs. The price factor shows a significant and positive influence on the preference consumers have for PLBs, but not on perceptions and patronage intentions. This study has practical implications for department store executives and managers on how to allocate resources in order to increase positive consumer perceptions toward PLBs, preferences over other brands, and patronage intentions of PLBs at a store as well as how to create effective store environments to promote PLBs.

The purpose of this study is to investigate the direction of how to educate water shortage problem to middle school students. In the reality that many people of the world have been painful of the water shortage problem, Korea is classified as 'water shortage country'. Here, we investigated the awareness of middle school students about the contents related to the water shortage problem by surveying with the questionnaires developed in this study. And we analyzed how water shortage problem appeared in the environmental textbook of middle school. Based on these, we examined the direction of environmental education in middle school on the theme of the water shortage problem. The results of the survey showed that students revealed difference of knowledge and experience, and also revealed difference of knowledge and feeling related to the water shortage problem. The students had the knowledge about water shortage problem but they did not have experience in their real lives. Also, the results of the survey showed that students had attitude of waste in water use, even though they had awareness and knowledge about the importance of water resources. And the students did not have enough knowledge related to the water shortage problem. From the analysis of the textbooks, We found that the contents were not composed to enhance deep understanding of the students about the water shortage problem. Based on the analysis of the results, the directions of middle school environmental education in Korea about water shortage problem were extracted in this research.
