In 1995, the department of multimedia-related study was first founded in Technical Institute and has carried out the fundamental education at academic level in trial and error. Following a bubble situation of multimedia-related industries, the education of multimedia-related departments has mass-produced hurriedly prepared multimedia designers and programmers. With the current IMF economic crisis, demand for the multimedia expert manpower has shrunk drastically and competitiveness for getting a job becomes intense. Therefore, it is an urgent problem to specialize the multimedia education of Technical Institute and to differentiate it from the education of Universe. In this paper, I am going to analyze the cause of various practical problems occurring in the multimedia education in Technical Institute and to suggest the solution and education goal for the specialized and differentiated education in multimedia-related department of Technical Institute.

In this study, the information literacy educational program currently used by Korean universities was applied to foreign ones and its educational effect was analyzed and their degree of satisfaction and demands were understood. As a result, the educational effect was shown, but the average knowledge of academic information used still remained low, but the satisfaction degree of education for information literacy was high, which means that such education is absolutely needed for foreign students. The analyzed results and contents carried out in the experiment will be very helpful for designing a differentiated information literacy educational program for foreign students.

Excessive growth of phytoplankton is a common and severe problem in intensively farmed pangasiid catfish (Pangasius hypophthalmus) culture ponds. It can lead to cyanobacterial blooms, reduced fish growth, bad-tasting fish flesh, and lower market demand. To investigate how to manage undesirable phytoplankton growth, we evaluated three stocking strategies in nine rural fishponds (0.020-0.022 ha) owned by various farmers: a pangasiid catfish mono culture (treatment 1, $T_1$), and pangasiid catfish-silver carp (Hypophthalmichthys molitrix) polycultures at two stocking ratios of 1:1 (treatment 2, $T_2$) and 2:1 (treatment 3, $T_3$). The total density of all ponds was approximately 30,000 fishes/ha. Monoculture ($T_1$) resulted in significantly higher (p < 0.05) nutrient levels (nitrate and phosphate) in ponds than did polyculture ($T_2$ and $T_3$). Nutrient loads increased with culture time, resulting in increased growth of phytoplankton, including Cyanophyceae (9 genera), Chlorophyceae (15 genera), Bacillariophyceae (8 genera), and Euglenophyceae (3 genera). The introduction of silver carp as a co-species helped to regulate phytoplankton growth and to improve the water quality of pangasiid catfish culture ponds.

Purpose Real estate usually takes charge of the highest proportion of physical properties which individual, organizations, and government hold and instability of real estate market affects the economic condition seriously for each economic subject. Consequently, practices for predicting the real estate market have attention for various reasons, such as financial investment, administrative convenience, and wealth management. Additionally, development of machine learning algorithms and computing hardware enhances the expectation for more precise and useful prediction models in real estate market. Design/methodology/approach In response to the demand, this paper aims to provide a framework for forecasting the real estate market with machine learning algorithms. The framework consists of demonstrating the prediction efficiency of each machine learning algorithm, interpreting the interior feature effects of prediction model with a state-of-art algorithm, LIME(Local Interpretable Model-agnostic Explanation), and comparing the results in different cities. Findings This research could not only enhance the academic base for information system and real estate fields, but also resolve information asymmetry on real estate market among economic subjects. This research revealed that macroeconomic indicators, real estate-related indicators, and Google Trends search indexes can predict real-estate prices quite well.

Nothing is more incorrect than forecasting. Nevertheless, forecasting is one of the most important business activities for the effective management. There has been rapid changes of the growth rate in every respect of the Korean hospitaity industry, especially the hotel industry, before and after the 88 Olympic Games. Therefore, the hoteliers shall be in need of more-than-ever accourate demand forecasting for the more systematic management and control. Under the above circumstances, this study suggested the best forecasting technique and method for the better sales and operations of the hotel rooms. The number of rooms sold is selected as a dependent variable of this study which is regarded as the best representative factor of measuring the growth rate of the rooms division performance of the hotels. The first step was to select the most verifiable independent variable diferently from the other countries or other areas of Korea. As a result, the number of foreign visitors was chosen. Empirical research, i.e. correlation and multiple regression analysis, shows that this independent variable has a strong relationship with the dependent variable told above. The second procedure was to estimate the number of rooms will be sold in 1991 on the basis of the formula calculated through the multiple regression analysis. Time series technique was conducted using the data of the number of foreign visitors by purpose of travel from 1987 to 1990. For the more correct forecasting, however, it would be desirable to adopt the data from 1989 considering the product or the industry life cycle. In addition, deeper analysis for the monthly or seasonal forecasting method is needed as a future research.

Purpose: This study was conducted to investigate the recognition on center-based child care health programs for parents with ill children. Methods: Cross-sectional descriptive study with convenient sampling method was used and 136 parents were recruited from two university hospital outpatient departments and hospitalized wards, and they completed a structured questionnaire. Results: Majority (57.4%) of parents experienced a leaving work early or being absent from their work due to children's illness. Most dissatisfying factors in child care centers were child health management. Most of parents agreed on the need for a center-based child care health program, and wanted a better management of health care by health professionals in child care centers. Conclusion: These results support that there is a great demand for center-based child care health programs. These special programs are needed for reducing a child rearing burden for working mothers and overcoming the low birthrate in Korea. Health-care programs in child-care settings can help parents meet the health needs of their children while reducing absenteeism from work, thereby contributing to job stability. These results suggest discussions of the related policy with child care centers responsible and national health and educational authorities.

Despite of increasing importance of management in healthcare administration and demand for the professional managers in hospitals, there have been few studies on the issues of competencies and qualifications of mid-managers for effective role performance. This article uses hospital mid-managers' judgements to discuss them in Korean hospital settings. Based on 67 questionnaires completed through the mail survey, the data were analyzed by chi-square test, t-test, ANOVA, and logistic regression. The result shows that knowledge of management skills in healthcare field is the most necessary area in general. Specifically, 'problem-solving ability' is the most important competency, followed by communication and planning capabilities. The mid-managers tend to consider the hospital employment history more important than the academic level. They also present the willingness to recruit the candidates with bachelor degrees rather than those with master or Ph.D. degrees. It is suggested that the candidate with bachelor degree and hospital employment over 6 to 10 years is the most qualified for a mid-manager in hospitals. The study results presented in the paper will provide the direction to improve the educational program and also the insights toward a advising strategy for job consultation for students majored in health service administration.

It is noted that although the current state of development of web-based English education (hereafter referred to as WBEE) might not meet the criteria some educators have set for themselves in the field, students certainly seem to prefer studying in a web-based and computer-assisted learning environment. This kind of demand is fueling the drive to develop more suitable variations of WBEE. In order for WBEE to work out, a teacher should be a multifunctional type of instructor handling responsibilities such as the role of scriptwriter to create text, act as technician for the sound mixing and recording, preside over online chat rooms and discussion boards, and finally, as webmaster to maintain the site and supervise all academic/ clerical work related to the course. Therefore, it is suggested that WBEE be accompanied by a small personnel to divide the labor and lessen the burden on the actual teacher. Finally, it is noted that the traditional relationship between students and teacher may no longer be sustainable since WBEE does not provide the face-to-face style of class discussion and office hours in its current form. Until the technology is fully developed to compensate for these kinds of differences, it is an immediate challenge to provide other more compelling reasons for students to participate in WBEE.
