This study has improved the existed physical disturbance evaluation assessment technique in a river and analysed its applicability. The improvements are the quantitative evaluation items instead of qualitative one by providing the background and their evaluation equations, corresponding detailed itemization of evaluation score, and the direct input of hydraulic characteristics and geometrical changes by numerical simulation. In order to confirm the applicability of improved disturbance evaluation technique, the comparison and analysis between the evaluation results of existed and improved techniques have been carried out by applying to the 6 cases of natural, urban, and mountainous streams. Direct input of numerical simulation results of HEC-RAS enables the evaluation simple for 8 evaluation items excluding the items of habitat environment and bottom substrate. The improved disturbance evaluation technique, which evaluates the degree of disturbance sensitively by the quantitative and detailed itemized evaluations, has been confirmed the appropriate applicability by applying to river systems.

In this study, we analyzed the characteristics of science academic achievement by multiple culture and North Korean migrant students types, percentage of correct answer and discrimination per items per groups, and contents domains using quantitative and qualitative method in the National Assessment of Educational Achievement (NAEA). As a results of analysis, the degree of science academic achievement of the students from multiple culture and North Korean is much lower than that of the general students. Also, the science academic achievement of the students from multiple culture and North Korean migrant is different from the general students. Especially, science academic achievement of the immigrated students and the North Korean migrant students was lowest. The analysis of items that the difference of the percentage of correct answer was large showed that the students from multiple culture and North Korean migrant were equally weak to it in all contents domains, but that the students from international marriage family born in country were weak in some areas. Therefore, the appropriate the teaching and learning method and the educational support is needed considering the group situation, so the educational implications are discussed.

This study was intended to find the characteristics of the middle school students' thinking processes and problem spaces when they solved the physics problems. Ten ninth grade students in Chon-Buk Do, Korea were participated in this study. The researcher investigated their thinking processes in solving 5 physics problems on electric circuit. "Thinking aloud" method was used as a research method. The students' thinking processes were recorded using an audio tape recorder and transfered into protocols. The protocols were analyzed by problem solving process coding system which was developed by Lee(1987) on the basis of Larkin's problem solving process model. The results are as follows : (1) On the average 2.85 items were solved among 5 test items, and only one person could solve all of the items correctly. (2) Problems were solved in sequence of understanding the problem, planning, carrying out the plan, and evaluating steps regardless of the problem difficulty. (3) In regard to the thinking process steps, there was no difference between the good solvers and the poor ones. But in the detail performance of problem solving, the former was different from the latter in respect with using the design of general solving procedure. (4) The basic problem spaces by the item analysis were divided into two classes. One was the problem space by using Qualitative approach in problem solving, and the other was one by using Quantitative approach. As novices in physics problem solving, most of the students used the problem space by using the Quantitative approach.

The fashion designers in Korea can achieve the winning position in the competitive international market of fashion industry by adapting our own traditional beauty to the modem fashion design through the modernization of the Korean traditional styles. Therefore, this study attempted to analyze the works of the active Korean fashion designer, Lee Young-Hee, focusing on the subject how she incorporated the modem fashion with the elements of Korean traditional costume. In order to study this subject, both quantitative and qualitative research methods were used to collect and analyse the design elements of Korean costume used in the designer's works found from the major fashion magazines, FASHION TODAY, WWD, ELLE, BAZAAR, Marie Claire, Areumdown-Uri-Ot, The Beauty of Korea and FASHION SHOW from 1993 to 1999. The collected research data, 95 works, was counted and analyzed in terms of the formal characteristics borrowed from Korean traditional clothing items and their application techniques. Other aesthetic characteristics of her works such as color, fabric and pattern were also analyzed. As a result of the study, it was found that Lee Young-Hee has adapted many different kinds of major Korean clothing items including 'chima', 'paji', 'po', and 'chogori'. Also it was apparent to note that the formal characteristics of Korean traditional clothing items were successfully incorporated into her fashion design works expressing the beauty of oriental grace, naturalism, sophistication, and above all, the modem sense.

Spiritual health is an important indicator in the quality of life of patients with cancer. The purpose of this study was to validate a Spiritual Health Inventory (SHI) for patients with cancer developed by Highfield (1989). The SHI was translated into Korean, back-translated into English. The study sample was 96 patients with cancer. The data were collected from September, 1999 to February, 2000 for 6 months. Statistic analysis was done with the SPSS PC+ (Version 10.0) program: descriptive statistics, factor analysis, Pearson correlation coefficient, and one-way ANOVA. The results are as follows : 1. The reliability score was examined using Cronbach's ${\alpha}$ and found to be .79. 2. Construct validity was examined using factor analysis. Four factors were identified and named : (1) Peace of mind (19.1% of variance), (2) Hope (9.7%), (3) Self-esteem (6.4%), (4) Trust (6.0%). The total of 41.2 percent of the variance. 3. The Pearson correlation coefficient score of 4 factors was between r = .24~ .42. 4. SHI was identified as multidimension, that is (1) The relationship with GOD, as absolute being, (2) the relationship with others, (3) the relationship within oneself. 5. There were differences in response in items especially related to GOD. The following recommendations can be made on the above findings : 1. Replicate with a minimum sample of 150 and test for concurrent validity. 2. Since spirituality is a dynamic concept, longitudinal study is also necessary. 3. Concept analysis using a qualitative study based on religious preference is recommended. 4. The items such as 12, 13, 15, 17, 19, 22, 24, 26 indicated conceptual ambiguity for Korean populations and further study is needed on item deletion or new items.

The purpose of this descriptive study was to identify problems and solving strategies on student evaluation of clinical nursing education. Subjects were 239 nurses in 18 hospitals from February to July, 1999. Content analysis using qualitative research method was used to analyze data taking into account the semi-structured questionnaire. The results of this study were as follows: Four categories about problems and solving strategies on the evaluation of clinical nursing education were identified: 'The environment of the clinical nursing education'; 'contents and items of evaluation tool'; 'criteria of evaluation tool'; and 'problems with evaluators in clinical settings'. The problems of the environment of the clinical nursing education were due to the lack of co-ordination between nursing schools and hospitals. In order to solve these problems, the following strategies were suggested: 'initiate a joint meeting between nursing schools and hospitals'; 'do not change the clinical settings frequently'; 'evaluate students after being familiar with them'; and 'evaluate them immediately after clinical practice was ended'. In the problems of contents and items of the evaluation tool, the contents of the tool were very abstract and general. The strategies for treating these problems were to evaluate student using the concrete evaluation items'; refrain from evaluation of nursing knowledge', develop the evaluation tools that are fit for a specific clinical setting'; develop the evaluation tools in line with students' knowledge level; and 'carry out evaluation using the proper contents of tool. The problems of criteria of the evaluation tools were the results of the lack of the clear criteria. The strategies for treating these problems were 'develop the criteria of the evaluation tool'; simplify the range of the cores or evaluate students using check-list'; to evaluate students in objective manner'. The problem of evaluators in clinical settings was due to the failure by evaluators who were not prepared for the task. The strategies were 'to educate and prepare the evaluators before evaluation'.

This study proposes a novel recommender system using the structural hole analysis to reflect qualitative and emotional information in recommendation process. Although collaborative filtering (CF) is known as the most popular recommendation algorithm, it has some limitations including scalability and sparsity problems. The scalability problem arises when the volume of users and items become quite large. It means that CF cannot scale up due to large computation time for finding neighbors from the user-item matrix as the number of users and items increases in real-world e-commerce sites. Sparsity is a common problem of most recommender systems due to the fact that users generally evaluate only a small portion of the whole items. In addition, the cold-start problem is the special case of the sparsity problem when users or items newly added to the system with no ratings at all. When the user's preference evaluation data is sparse, two users or items are unlikely to have common ratings, and finally, CF will predict ratings using a very limited number of similar users. Moreover, it may produces biased recommendations because similarity weights may be estimated using only a small portion of rating data. In this study, we suggest a novel limitation of the conventional CF. The limitation is that CF does not consider qualitative and emotional information about users in the recommendation process because it only utilizes user's preference scores of the user-item matrix. To address this novel limitation, this study proposes cluster-indexing CF model with the structural hole analysis for recommendations. In general, the structural hole means a location which connects two separate actors without any redundant connections in the network. The actor who occupies the structural hole can easily access to non-redundant, various and fresh information. Therefore, the actor who occupies the structural hole may be a important person in the focal network and he or she may be the representative person in the focal subgroup in the network. Thus, his or her characteristics may represent the general characteristics of the users in the focal subgroup. In this sense, we can distinguish friends and strangers of the focal user utilizing the structural hole analysis. This study uses the structural hole analysis to select structural holes in subgroups as an initial seeds for a cluster analysis. First, we gather data about users' preference ratings for items and their social network information. For gathering research data, we develop a data collection system. Then, we perform structural hole analysis and find structural holes of social network. Next, we use these structural holes as cluster centroids for the clustering algorithm. Finally, this study makes recommendations using CF within user's cluster, and compare the recommendation performances of comparative models. For implementing experiments of the proposed model, we composite the experimental results from two experiments. The first experiment is the structural hole analysis. For the first one, this study employs a software package for the analysis of social network data - UCINET version 6. The second one is for performing modified clustering, and CF using the result of the cluster analysis. We develop an experimental system using VBA (Visual Basic for Application) of Microsoft Excel 2007 for the second one. This study designs to analyzing clustering based on a novel similarity measure - Pearson correlation between user preference rating vectors for the modified clustering experiment. In addition, this study uses 'all-but-one' approach for the CF experiment. In order to validate the effectiveness of our proposed model, we apply three comparative types of CF models to the same dataset. The experimental results show that the proposed model outperforms the other comparative models. In especial, the proposed model significantly performs better than two comparative modes with the cluster analysis from the statistical significance test. However, the difference between the proposed model and the naive model does not have statistical significance.

This study was conducted to evaluate the quality in medical records by analyzing its completeness through setting up the level of record on the patient's past history and through examining the actual medial records. Targeting the information on the patient's past history in interns' records, residents' records and nurses' records toward 403 inpatients who were admitted first in 2004 at an university hospital due to stomach cancer. We analyzed whether the charts were recorded or not, recording level, the satisfaction with the expectant level of the records in the hospital targeted for a research and the level of agreement. The results were as follows; first, as for the rate of recording those each items, they were high in the chief complaint & present illness and the past illness history. Depending on the group of recorders, the recording rate showed big difference by items. Second, as a result of measuring the level after dividing the recording level of items for the patient's past history from Level 1 to Level 4 by each item, the admission history, the past illness history, and the family history were about Level 3, and the smoking history, the medication history, the chief complaint & present illness, the drinking history and allergy were about Level 2. In the admission department, it was excellent in the interns' records for the medical department. Third, as a result of its satisfactory level by comparing the expect level of a record and the actual record by item in information on the patient's past history, which was expected by the medical-record committee members of the hospital targeted for a study. And forth, we analyzed the level of agreement with Kappa score in the level of 'Yes' or 'None' related to the corresponding matter in Level 1, in terms of information on the past history in the intern's record, the resident's record, and the nurse's record. The level of agreement in the resident's record & the nurse's record, and in the intern's record & the resident's record was from "excellent" to "a little good". There were differences in the level of completeness and in reliability for the information on the past history by the recorder group or by the admission department. The encounter process that was performed by the admission department or the recorder group, indicated the result that was directly reflected on the quality of medical records, thus it was required further study about the medical record documentation process and quality of care. The items that showed the high recording rate quantitatively were rather low, consequently we'd should develop the tool for the qualitative inspection and evaluate the medical records further. And the items were needed to be detailed in the record level were rather low, and hence there needed to be a documentation guideline and education by the clinical departments.
