The purpose of this study was to develop a scale to access a creative home environment for preschool children and to examine its validity and reliability. The subjects were 296 children aged 5 to 6 years(148 males and 148 females) and their parents. The methods for data analysis included item analysis, factor analysis for construct validity, Pearson correlations between the rating scale for creative characteristics of preschoolers(RSCCP) and this scale for concurrent validity, and Cronbach's ${\alpha}$ for reliability. The 44 items of the scale were found be satisfactory in terms of item response distribution and item discrimination. Four factors were extracted from the factor analysis: the subscales labelled 'respect for the child', 'enriched learning environment', 'stimulation of independence' and 'family pressure'. The concurrent validity of this scale was accessed by computing the correlation measures of RSCCP with this scale. Most coefficients were significant. Cronbach's ${\alpha}$ ranged from.75 to.86 for the 4 subscales and.85 for the total scale.

In this paper, a risk analysis methodology applicable to shield TBM tunnels was studied. Fault Tree Analysis (FTA) was utilized to identify all risk items and to calculate the probability of failure of each item and Analytic Hierarchy Process (AHP) was used to obtain the impact of each risk item. Finally, a risk level of each risk item can be assessed. Developed methodology is applied to a Seoul subway site in which EPB shield tunnel method was utilized and it was found that risk analysis results matched reasonably well with field data.

The purpose of this study was to evaluate wearing evaluation method in order to propose well fitted bodice pattern. For this study, the subjects were drawn from obese boys at the ages 9 to 11. Wearing evaluation had use of 3 bodice type and 3 evaluative method. The appearance evaluation was to evaluate subjects by professional group. The functional evaluation was to valued subjects by self-evaluation. The quantitative evaluation was to estimate subjects through Electomyograph. Wearing evaluation was done through questionnaire of 32 item in objectivity, 36 item in subjectivity, and 36 item in quantity. The data were analyzed by using ANOVA. From wearing evaluation, appearance and functional evaluation had significant most of them but quantitative evaluation had not significant. It was known that the human sense was more sensitive the quantitative mechanism. And its obtained by both functional evaluation and quantitative evaluation, respectively was found to be significantly correlated, Independent relation was observed in the results from both appearance evaluation and functional evaluation as well as from both functional evaluation and quantitative evaluation. Therefore, we propose that it is proper to evaluate the propriety of bodice pattern for obese boys of school year, mutually compromising both appearance evaluation and functional evaluation or both functional evaluation and quantitative evaluation.

The purpose of this study was to develop and validate the scale to measure dementia patient's caregiver burden of Korea. In the first phase of the study, 15 caregivers of dementia patients were interviewed to provide narrative data from which items were developed. Initially 65 items were generated from the interview data of 15 caregivers. Content validity was judged by two separate panels of experts with 27 professionals and 30 family caregivers. These items were analyzed through the Index of Content Validity and 33 items were selected which met .80 or more of the CVI. This preliminary FCBSD-K was tested with 207 adult caregivers for reliability and construct validity including item analysis and orthogonal(Varimax) factor analysis. Eight items were deleted because of high or low item-item correlation. The result of the second factor analysis produced six factors that coincided with the conceptual framework posed for the scale developed. The six factors were labeled as 'physio social factor' 'emotional factor' 'family cultural factor' 'role obligation' 'guilt feeling' and 'financial & supportive system factor'. The alpha coefficient relating to internal consistency was .9264 for reliability. In conclusion, cultural factor is related to dementia patient's caregiver burden and FCBSD-K was useful in assessing the dementia patient's caregiver burden in Korea.

Purpose: The purpose of this study was to develop and evaluate a quality of life scale for Korean patients with cancer (C-QOL). Methods: The C-QOL was developed and validated as follows, item generation, pilot study, and psychometric tests. A total of 337 patients diagnosed with stomach, liver, lung, colon, breast, or cervix cancer were recruited. The patients were asked to complete the preliminary questionnaire comprising the content-validated items, the SF-36, and the ECOG performance status. The obtained data was analyzed using descriptive statistics, factor analysis, multidimensional scaling (MDS), multitrait/multi-item matrix, ANOVA, t-test, and Cronbach's alpha. Results: Preliminarily twenty-six items were generated through content validity and a pilot study. Factor analysis and MDS extracted a total of 21 items with a 5-point Likert-type scale (C-QOL). The C-QOL included five subscales: physical status (6 items), emotional status (6 items), social function (3 items), concern status (2 items), and coping function (4 items). The C-QOL established content validity, construct validity, item convergent and discriminant validity, known-groups validity, reliability, and sensitivity. Conclusion: The Newly developed C-QOL is an easily applicable instrument which established psychometric properties and reflected Korean culture. It is recommended for further study to examine the responsiveness of the C-QOL using a longitudinal research design.

This study aims to suggest improvement plans and explain about the current situation for facilitating Long-life housing, based on the results on flexibility items among 27 items consisting the "Housing Performance Grading System". From the 9th of January, 2006 to the month of July in 2011, study has analyzed evaluation results on 216 different types for each grade and reviewed evaluation criteria and methods. Current evaluation criteria applies quantitative analysis, by calculating in percentage how much bearing walls and columns, which hinder flexibility, take up space in the household. The evaluation rate for each household was assessed in relation to its structural system, and a higher grade was given to column-typed structures. In addition, to facilitate long-life housing, this study extracted harmful factors, expanding the range of evaluation. The first step was to evaluate structure, which is the basic element. The second step can to evaluate the probability of applying resources in response to the changes of structural systems. As The third step, Flexibility item will evaluate the probability of moving the water-using area, suggesting gradual approach. Thus, through evaluations of flexibility items, the study aims to improve the quality of life in household, by avoiding uniform structures and acquiring more freedom for space designs.

In this paper, we propose an efficient algorithm which generates frequent itemsets by only one database scanning. A frequent itemset is subset of an itemset which is accessed by a transaction. For each item, if informations about transactions accessing the item are exist, it is possible to generate frequent itemsets only by the extraction of items haying an identical transaction ID. Proposed method in this paper generates the data structure which stores transaction ID for each item by only one database scanning and generates 2-frequent itemsets by using the hash technique at the same time. k(k$\geq$3)-frequent itemsets are simply found by comparing previously generated data structure and transaction ID. Proposed algorithm can efficiently generate frequent itemsets by only one database scanning .

This paper describes the fault diagnosis method to order to construct CIM in complex system with hierarchical structure similar to human body structure. Complex system is divided into unit, item and component. For diagnosing this hierarchical complex system, it is necessary to implement a special neural network. Fault diagnosis system can forecast faults in a system and decide from the signal information of current machine state. Comparing with other diagnosis system for a single fault, the developed system deals with multiple fault diagnosis, comprising hierarchical neural network (HNN). HNN consists of four level neural network, i.e. first is fault symptom classification and second fault diagnosis for item, third is symptom classification and forth fault diagnosis for component. UNIX IPC is used for implementing HNN with multitasking and message transfer between processes in SUN workstation with X-Windows (Motif). We tested HNN at four units, seven items per unit, seven components per item in a complex system. Each one neural network represents a separate process in UNIX operating system, information exchanging and cooperating between each neural network was done by message queue.

Purpose: The aim of this study was to validate the Korean version of World Health Organization Disability Assessment Schedule 2.0 (KWHODAS 2.0) in 12 item-self administered version (12-self). Methods: The KWHODAS 2.0 and Korean Functional Rating index (KFRI) were tested for internal consistency, ceiling and floor effects, and concurrent validity in 111 patients with low back pain and/or neck pain. Results: A very high level of internal consistency was shown for both instruments; ${\alpha}$=0.96 with KWHODAS 2.0; 12-self and ${\alpha}$=0.97 for KFRI. No ceiling and/or floor effects were found in both the instruments. The KWHODAS 2.0 and KFRI were highly correlated (r=0.77), and the relationship of each item between KWHODAS 2.0 and KFRI was ranging from r=0.09 to 0.72. Conclusion: We conclude that the KWHODAS 2.0: 12-self and KFRI are reliable and are valid instruments for the measurement of disability in Korean speaking patients with low back and/or neck pain. Both instruments, the KWHODAS 2.0; 12-Self and KFRI are now suitable for use in clinical practice and research applications.
