Though many services offer useful information on internet, computer users are not so familiar with such services that they need an assistant system to use the services easily In the case of web sites, for example, the operators answer the users e-mail questions, but the increasing number of users makes it hard to answer the questions efficiently. In this paper, we propose an assistant system which responds to the users questions automatically and helps them browse the Hanmail Net FAQ (Frequently Asked Question) conceptually. This system uses two-level self-organizing map (SOM): the keyword clustering SOM and document classification SOM. The keyword clustering SOM reduces a variable length question to a normalized vector and the document classification SOM classifies the question into an answer class. Experiments on the 2,206 e-mail question data collected for a month from the Hanmail net show that this system is able to find the correct answers with the recognition rate of 95% and also the browsing based on the map is conceptual and efficient.

In a traditional customer support environment, mainly call centers or service centers are responsible for receiving inquiries from their customers via telephone calls. Due to the rapid growth of Internet with its widespread acceptance and accessibility, means of communication with customers in the traditional customer support center, such as telephones, letters, and direct-visiting, have been replaced by e-mails and bulletin board systems (BBSs) using the Internet constantly. BBSs are basically question and answer systems, they require some lead time to get answer from administrator. To reduce lead time, BBSs enable remote customers or users to log on and tap into a knowledge database that is generally formatted in the form of Frequently Asked Questions (FAQs) that provide answers and solutions to the common problems. And, many different types of the questions are mixed on the BBS. It is a burden to administrator. To build FAQs and to support BBS adminstrator, a supporting tool which is to categorize questions is helpful. In this research, we suggest an interactive question categorizing methodology which consists of steps to present question using keywords, identifying keywords' affinity, computing similarity among questions, and clustering questions. This methodology allows users to interact iteratively for clear manifestation of ambiguous questions. We also developed a prototype system, IQC (interactive question categorizer) and evaluated its performance using the comparison experiments with other systems. IQC is not a general purposed system, but it produces a good result in a given specific domain.

2002 was the first year that the export of Korean TV programs exceeded the import. Particularly, there is no doubt that dramas, as for a genre, dominated the market, from 64.3% in 2001 to 93.6% in 2003. Especially, the increasing demand from the Chinese block such as Taiwan, China and the neighbor countries like Vietnam, Indonesia, Malaysia, and the preference of Korean drama in Japan shows the continuation of booming Korean wave. Questions frequently asked in this current circumstance may be what kind of dramas are better to be exported and to which country Korean dramas are exported. Based upon those needs, this paper examines the determining factors of Korean drama exports to foreign countries. Especially, this study examines the internal factors to the drama influencing export by countries. For this study, 594 Korean dramas aired on MBC and exported between 2002 and 2005 will be analysed by chi-square analysis.

The present research is a study of the feared objects of children between 7 and 12 years of age. The data consisted of the replies to a questionnaire by 802 children and their mothers in Chun Chon City and Chunsung and Wonsung Counties plus. The questionnaire was divided into parts: 6 questions were designed to be answered by the children and 22 by their mothers. The children were asked about their feared objects, feared places, and feared colors, whereas their mothers about their own feared objects plus the backgrounds of their children's fear-objects. Frequency, percentage, and $X^2$-test were applied to the statistical analysis. The results were as follows: 1. Ghost (Kuishin), Devil (Toggaebi), and animals turned out to be the main feared objects of children. 2. Children's feared objects were same regardless of differentiating ages and regional backgrounds. Sex was the only factor which caused any differences. Girls were more sensitive to the animals as their feared objects. 3. Red and black proved to be the most frequently feared colors for all children. 4. Children's feared objects were influenced by the feared objects of their parents, grand parents and sisters and brothers. 5. Children's feared objects were related to the fairy tales and stories they have been told by their mothers.

Background and objective: This study seeks to investigate domestic agro-healing farm resources so that preliminary data can be obtained on the systematic provisions for agro-healing programs in order to improve service quality and to identify the quality of agro-healing policy services. Methods: For this study, owners of agro-healing facilities were asked 24 questions via an online survey. An importance-performance analysis (IPA) was conducted to identify service quality for each policy sector. Results: Respondents' satisfaction levels were low when compared to agro-healing farm owners' perceptions of the above-average importance of each sector. The results from the resource analysis of domestic agro-healing farms indicated that the main operational purposes of farms were, in descending order, experience (90.0%), healing (86.7%), and education (84.0%). With respect to the type of program that was operated, cultivating crops (horticultural therapy) was identified most frequently at 83.3%. Conclusion: As a result of this study, the resources possessed by agro-healing farms were identified. In addition, the results of the IPA analysis in terms of service quality are not as good as expected, and performance levels should be increased to improve this. The results of this study are expected to provide useful information not only to improve the quality of agro-healing services, but also to revitalize the agro-healing industry while developing a systematic agro-healing program.

Purpose: The purpose of this study was to describe the approaches, methods and questions asked in intensive care unit studies published in Korean journals and the American Journal of Critical Care (AJCC) from 1992 to 2011. Only quantitative studies were reviewed. Methods: A total of 144 studies published in four Korean Journals and 521 studies published in American Journal of Critical Care (AJCC) were analyzed using descriptive statistics. Results: The most frequently used research design reported in Korean journals were surveys (83.5%), protocol development (10.1%), and randomized controlled trials (6.2%). In AJCC, the most frequently reported design was survey research (90.4%) and randomized controlled trials (16.1%). The most frequent nursing intervention reported in the AJCC was tube care (10.8%), and in Korean journals the intervention of suctioning (10.8%). In Korea, nurses were more likely to study instrument measurements (31.0%) and positioning (13.5%). In reported studies in the AJCC there were more reports on emotional support, exercise, and measurement research. Conclusion: There is overlap in the type of studies between the two countries in term of study design, whereas the types of nursing problems studied differed in United States and Korea. The result suggests that there were gaps and those more diverse studies and physiological measurements are needed.
