This study was conducted to develop a sexual satisfaction tool for married women in Korea. The data was collected from July 19 to Aug 18, 1997 by means of questionnaires developed by researchers. The subject were 417 married women living in Seoul and Pusan. The process of this study was as follows : 1) The concept of sexual satisfaction was defined. 2) A conceptual framework was identified based on the extensive review of relevant literature and interviews with married women. 3) The preliminary question items containing the attributes and elements of the concept of sexual satisfaction were listed. 4) The preliminary items were revised after a pilot study. 5) The Index of Content Validity(CVI) was calculated from the content specialists' rating. 6) The reliability and validity of the sexual satisfaction measurement tool were tested. As a result of the item and factor analysis, 17 out of 30 items were found to be valid, consequently could be used to measure sexual satisfaction for married women. These final 17 items were divided into two factors. These factors were labeled as "situation factor" (10 items) and "response factor"(7 items) according to the attributes of the clustered items. The reliability of the final 17 items was .9118. Further research is needed to confirm the reliability and validity of the tool by applying it to a group of healthy married women and to a group of married women having health-related problem.

For extracting and processing information explicitly from given data, Formal Concept Analysis(FCA) is provided a method which is widely used for data analysis and clustering. The data can be structured into concepts, which are formal abstractions human thought allowing meaningful comprehensible interpretation. However, most FCA tools mainly focus on analyzing one-valued contexts that represent objects, attributes and binary relations between them. There we few FCA tools available that provide scaling and analyzing many-valued contexts representing objects, attributes and relations with attributes' values. In this paper, we propose not only a scaling algorithm for interpreting and simplifying the multivalued input data, but also an algorithm to generate concepts and build concept hierarchy from given raw data as well. Based on these algorithms, we develop an automate tool, FCA Wizard, for concept analysis and concept hierarchy. We also present FCA Wizard based applications in medical domain.

The purpose of this thesis is to develop a performance rating training tool for the time and motion study. It is widely recognized that rating training tools based on films were made several decades ago and introduced to Korea. However, to the best of our knowledge, those films are not used for rating training in Korea any more. Furthermore, although rating is still important method for the efficient operational management study, it is briefly mentioned without any training or exercise. In this paper, we propose a simple rating training tool based on Excel with VBA. The mottoes of our development are the ease of acquisition and trainees' motivation. Test results show that trainees can obtain the concept of rating and the ability of accurate and consistent rating as they play a computer game sitting in front of the personal computer.

A recently developed finishing process using rotating magnetic field is known to be very efficient for the finishing of parts such as vacuum tube, sanitary tube, etc., which are difficult to be finished by the conventional finishing methods as they are generally curbed tubes. But, the finishing system using rotating magnetic field have the defect that is the cross section of workpiece only circle because of internal rotating tool. Therefore, new finishing process of the workpieces which cross section are not circle is important and required. magnetic abrasive jet machining is a new concept finishing process. It is the precision internal finishing method using working fluid mixed with magnetic abrasives, which is jetted into the internal surface of tube. And magnetic poles are equipped on external surface of tube. In this study new concept finishing process or, magnetic abrasive jet machining system was developed. machining condition was predicted using simulation and some characteristics of the finishing process was analyzed.

The purpose of this study was to examine the effects of cookbook making activities on young children's mathematical concept and writing development. The participants were comprised of 50 five-year-old children from two intact classes from a kindergarten in Gyeonggi province, and they were divided into an experimental and a comparison group. The experimental group participated in cooking activities and produced cookbooks as extension activities whereas the comparison group carried out only cooking activities. The results indicated that the children in the experimental group received statistically higher scores in mathematical concept- and writing-tests, suggesting that cookbook making activities are a useful educational tool for enhancing young children's mathematical concepts and facilitating their writing development.

The aim of this study was to make dental technicians recognize the importance of their professional self-concept, and to provide basic data to devise the educational programs and policies of establishing their positive professional self-concept. In addition, the investigator tried to present some improvement measures for dental technicians' actual services by examining their job satisfaction. Study findings are as follows: First, the score of study subjects' self-concept is 3.41($\pm$.58) (perfect score=5), middle or high in rank. As for the mean score of professional self-concept by realms, the self-concept of communication is 3.59($\pm$.67), the highest; the self-concept of leadership in the realm of professional service is 3.54($\pm$.75); the self-concept of skills is 3.50($\pm$.75); the self-concept of adaptability is 3.47($\pm$.69); and the recognizant level of satisfactory self-concept is 2.95($\pm$.81), below the normal. Second, as for the difference of professional self-concept according to general characteristics, such variables as age, marital states, and the length of one's service have a significant influence upon the recognition of self-concept. First, the self-concept of those whose age is between 31 and 35 is the highest (3.64$\pm$.49), and it is followed by that of those whose age is 36 and above (3.57$\pm$.77) and then that of those whose age is between 26 and 30 (3.31$\pm$.56)). And that of those whose age is below 25 is the lowest. The obove results show us that the professional self-concept of older study subjects is higher than that of younger ones in general(p<.01). As for marital states, that of married persons(3.54$\pm$.64) is higher than that of unmarried ones(3.35$\pm$.55)(p<.05). As for the length of one's service, that of longtime employees is higher than that of short-period workers(p<.01). In relation to positions, a manager's professional self-concept is the highest(3.89$\pm$.55) and that of an assistant technician is the lowest(3.17$\pm$.58). Study findings show that the professional self-concept of higher ranking technicians is higher than that of lower ones in general (p<.001). Based on the study findings, the investigator suggests followings: First, studies on the professional self-concept that is appropriate to the characteristics of dental technicians must be carried out with a new point of view. Second, a tool must be researched and developed in order for the professional self-concept of dental technicians to be measured. Third, if a new professional self-concept is established and a measuring tool is developed, a study on the relationship between dental technicians' professional self-concept and practice performance can be carried out again.

The study investigated the effect of a social constructivist model on changes of concept on 103 4th graders in three elementary schools. In particular, it analyzed whether the application of a concept circle map developed student understanding of the concept. After a one month study period, the 103 students took a pencil and paper test on changes of concepts learned. The results indicated that the social constructivist model positively influenced student concept development. In conclusion, a concept circle map used on a social constructivist model may be employed as a tool for diagnostic or formative evaluation.
