In Korea, there has been a rapid increase in the number and proportion of elderly people, especially in rural areas, due to improvements in the standard of living and medical technology. One of the main health problems for the elderly people is dental health, which can cause nutritional and health problems. Thus, in this study, the dental health status and health status in relation to nutritional intake were analyzed. A total of 155 rural-dwelling elderly people (68 males, 87 females) over the ages of 65 participated in this study. The subjects were classified into three groups; the no denture no teeth group, denture user group, and natural teeth group. The dietary intake, biochemical health status, and anthropometry were evaluated. Can-pro 3.0 was used to assess dietary intakes and the SPSS 12.0 program was used for statistical analysis. The results showed that the natural teeth group had better nutritional and dietary intake status than the no denture no teeth group. The dietary assessment showed that there were differences in food intakes among the groups, which depended on their dental health status. In conclusion, dietary management is required for the elderly since each group has a different ability to chew food depending on their dental health status. In addition, the elderly will need different therapeutic diets because of the high prevalence of chronic degenerative diseases.

In this study, we introduce the background and model for the Test of Practical Competency in ICT(TOPCIT), which is designed to diagnose and assess the competency of ICT industry related workers and software(SW) developers, and also attempt to derive meaningful policy implications for developing a global level of ICT SW competency evaluation system across the different cases in domestic and foreign countries with regard to the application and dissemination of the TOPCIT. First, we analyze the test results from surveys conducted a preliminary test (or a pilot test) for the process of global dissemination of the TOPCIT in 2015. Then, we attempt to compare the results with the domestic test results. The findings show that the average score between domestic and foreign test takers was similar, but in the highest score group, the number of domestic test takers was relatively higher than the number of foreign test takers. Moreover, the average score can be varied by the language ability, especially fluent in English, of test takers. Therefore, the findings suggest that the localization is one of the key components for building upon the global TOPCIT system.

The physiochemical properties of Rhododendron mucronulatum pollens were examined after the use of various extraction conditions. The levels of phenolic compounds and electron donating abilities (DPPH) were better after 80% (v/v) ethanol extraction than after water extraction. The content of phenolic compounds and the DPPH were high when the solvent ratio was 20X. The content of phenolic compounds was highest at $45^{\circ}C$ (347.60 mg/100 g). The DPPH was highest, at 67.93%, when extraction was performed at $25^{\circ}C$. An extraction time of 6 hr yielded the highest content of phenolic compounds (312.63 mg/100 g). The DPPH did not vary with extraction time. Both the levels of phenolic compounds and DPPH values rose when extractions were performed twice. In summary, a solvent ratio of 20X, an extraction temperature of $25-45^{\circ}C$, double extraction and an extraction time of 6 hare optimal for extraction, with maximal DPPH and phenolic content, of Jindalrae pollens.

XML is becoming a new developing tool of web technology because of its ability of data management and flexibility in data presentation. So it's well researched that the reusability and integration with learning objects such as text, image, sound, video and plug-in programs of web contents in computer education. But the research for storing, extracting and integrating metadata about learning object was needed prior to implementing online learning system to integrate and manage it. Therefore this study propose a new method of using web service of DBMS for extracting learning object's metadata in database server which located in 3-tier system. To evaluate the efficiency of proposed method, The test server and two DBMSs(MS SQL Server 2000 and Oracle 9i) which have 30 metadata was implemented and the response time of it was measured. The response time of it was short, but in order to using this method the additional programming with SAX/DOM was necessary.

Broiler chickens grow rapidly, and their nutrient requirements change daily. However, broilers are fed three to five diet phases, meaning nutrients are under or oversupplied throughout production. Increasing diet phases improves production efficiency as there is less time in the production cycle that nutrients are in under or over-supply. Nevertheless, the process of administering four or more diets is costly and often impractical. New technologies are now available to blend feed to match the daily nutrient requirements of broilers. Thus, the aim of this review is to evaluate previous studies measuring the impact of increasing feed phases on nutrient utilisation and growth performance, and review recent studies taking this concept to the extreme; precision nutrition - feeding a new diet for each day of the production cycle. This review will also discuss how modern precision feeding technologies have been utilised and the potential that new technologies may bring to the poultry industry. The development of a precision nutrition regime which targets daily requirements by blending dietary components on farm is anticipated to improve the efficiency of production, reduce production cost and therefore improve sustainability of the industry. There is also potential for precision feeding technology along with precision nutrition strategies to deliver a plethora of other management and economic benefits. These include increased fluidity to cope with sudden environmental or market changes, and the ability to alter diets on a farm by farm level in a large, integrated operation. Thus, the future possibilities and practical implications for such technologies to generate a paradigm shift in feed formulation within the poultry industry to meet the rising demand for animal protein is also discussed.

This study investigated how learning motivation affects satisfaction with training and employment services and its performance for participants in government-supported job skill development program of the clothing industry so as to provide fundamental data for developing a training program that fosters professionals and relieves the labor shortage in the clothing industry. 180 copies of questionnaires were statistically analyzed by SPSSWIN 21.0. Most trainees were low-income citizens in their 40s and 50s. They were divided into highly educated or low-educated. The results of the research are as follows: when the trainees were motivated by the goals of getting a certificate or a job, employment service satisfaction levels were influenced meaningfully. Secondly, educational satisfaction levels and occupational ability development also scored highly. Therefore, it is important to strengthen instructors' competency. Instructors must be required to have onsite experience so that they can provide authentic education that can be applied to the work field. The government should establish a compulsory training session for the trainers along with an incentive program so that they can catch up with up-to-date technology and trend. Third, the research shows that supporting business startup and job placement is important. Follow-up management systems should be provided in cooperation with relevant institutions of employment and business startups. Either outsourcing or placement of professional advisors is also needed.

Recently, the food industry has evolved into a new and innovative trend according to its globalization and change of food consumption patterns. However, it is hard for the traditional food industry in Korea to meet the changing consumers' needs because of its poorer quality control and lower industrialization technology than other advanced industries. Also the knowledges acquired through a lot of time and efforts would be lost after the human resources with tacit knowledges leave by their too much aging. Especially, the 21st century would be called as knowledge based society which means that knowledge be the important contributing factor in the economic growth. In this regard, this study aimed at proposing the knowledge based system for systematically managing or preserving knowledges of Mosisongpyun industry in Yeonggwang County to seek for the sustainable development of the traditional food industry in Korea. The knowledge based system of Mosisongpyun industry in Yeonggwang County is finally proposed as follows; First, hardware is composed with the necessary unit facilities such as interpretive center, learning and experience room, library, etc. And the integrating facilities such as Mosisongpyun theme park, traditional village, and knowledge industrialization support center are proposed. Second, software is composed with the necessary unit softwares such as the preservation manual of traditional knowledge and skill, web-site administrator, development of graded textbooks, development database software, etc. And the integrating softwares such as development of innovation and management ability in Mosisongpyun industry are proposed. Third, humanware is composed with the necessary unit programs such as exhibition, own training program, incubator support system, etc. And the integrating programs such as the farm association corporation, the testing and research institute, the institution of learning and training are proposed.
