  • The purpose of this study was to assess and compare discrepancy in the scores of uncertainty perceived by patients and nurses' interperson perception. For this study, 124 hospitalized patients and the same numbered nurses assigned for direct care of each 124 patients were selected from general ward of C. University Hospital in Seoul during the time period from September to November 1987. Degree of uncertainty was measured by 27 items modified from Mishel Uncertainty in Illness Scale (MUIS), and was utilized by a Likert type scale The data were analysed by Mcnemar-test. Unpaired t-test. ANOVA, Scheffe - test and Stepwise multiple regression. The results are summarized as follows : 1. The discrepancy in the scores of uncertainty perceived by patients and nurses' interperson perception showed significant differences in 23 of 27 items : 11 of 23 items showed that the scores of patients' perception of uncertainty were higher than that of nurses' interperson perception of uncertainty. but 12 of 23 items were revealed reversely. 2. With regard to nurse's demographic variables, the discrepancy scores were the higest in the group under 22 years of age (F=3.20, p=.026) and in the group less than 1 year of nursing experience among 4 groups (F=4.41, p=.006). 3. The discrepancy scores had a tendency to be lowered in the higher age group(r= -.27. p=.0026) and in the longer experienced group (r=-.25, p=.0052). 4. The most important variable affecting the discrepancy scores was identified to be the nurses' age which acounted for 7.2% fo the total variances in the stepwise multiple regression analysis. This was followed by patient hospital days which accounted for an additional 4.5% of the total variances. To conclude, the discrepancy in the scores of uncertainty perceived by patients and nurses' interperson perception showed significant differences in 23 of 27 items. The discrepancy scores of uncertainty had a tendancy to be lowered in the higher age group and in the longer experienced group.

  • The goal of this study is to examine the level of disposition conformity in everyday life and behavior conformity in clothes brand choice, and analyze the effects of disposition conformity and influential variables on behavior conformity in brand choice. For this analysis, the data were collected from 478 middle school and high school students in Seoul through surveys. Frequency, percentage, mean, standard deviation, Pearson's correlation coefficient, ANOVA, t-test, Duncan's multiple range test and multiple regression have been used to analyze the research objectives. Main findings are following; First, the 62.8% of the students showed high level of disposition conformity, and the 60.7% of them showed relatively low level of behavior conformity in brand choice. The adolescent consumers'disposition conformity to the reference groups in everyday life is in the order of parents, peer group, and mass media star. Second, the group differences in disposition conformity are diversified by independent variables. Among socio-demographic variables, disposition conformity to peer group differ by grade and disposition conformity to parents differ by the parents'education. Sex causes differences between groups in all disposition conformity except parents. In economic variables, the perceived level of living raises differences between groups in disposition conformity to the parent and whole disposition conformity. As the degree of disposable money gets higher in buying clothes, adolescent consumers conform more to the mass media star. Disposition conformity to parents and peer group were also differed by self-esteem. Third, significant variables, which affect the adolescent consumers'behavior conformity in brand choice, are grade, their mother's education, degree of disposable money in buying clothes, and disposition conformity to peer group and mass media star.

  • The premise of this research is the recent advancement of Building Information Modeling(BIM) Technology and Laser Scanning Technology(3D Scanning). The purpose of the paper is to amplify the potential offered by the combination of BIM and Point Cloud Data (PCD) for structural analysis. Today, enormous amounts of construction site data can be potentially categorized and quantified through BIM software. One of the extraordinary strengths of BIM software comes from its collaborative feature, which can combine different sources of data and knowledge. There are vastly different ways to obtain multiple construction site data, and 3D scanning is one of the effective ways to collect close-to-reality construction site data. The objective of this paper is to emphasize the prospects of pre-scanning and post-scanning automation algorithms. The research aims to stimulate the recent development of 3D scanning and BIM technology to develop Scan-to-BIM. The paper will review the current issues of Scan-to-BIM tasks to achieve As-Built BIM and suggest how it can be improved. This paper will propose a method of coordinating and utilizing PCD for construction and structural analysis during construction.

  • k (${\geq}2$) 그룹의 p-차원 데이터의 시각화에서 가장 전형적인 방법은 Fisher의 정준판별분석(canonical discriminant analysis; CDA)이다. CDA는 마할라노비스 공간에서 k개 그룹 중심을 근사하게 통과하는 저차원 부공간에 관측점들을 사영한다. 본 논문은 척도화 유클리드 공간에서 다그룹 다차원 데이터를 시각화하는 방법을 제안하는데, 저차원 부공간의 제1축(또는 제1축과 제2축)은 그룹 중심들의 최대변별(maximum discrimination)에서 찾고 부공간의 제2축(또는 제3축)은 관측개체들의 최대산포(maximum dispersion)에서 찾는다. 이러한 혼종방법(hybrid method)은 2-그룹 다차원 자료의 시각화에서 특히 유용하다.

  • Objectives: This study examined the milk intake patterns with lactose and milk fat in Korean male adults using the following variables: milk intake level, awareness of lactose, and milk fat, health problems, and necessity of milk intake. In addition, the factors affecting milk intake were analyzed by multiple regression analysis. Methods: The subjects were 532 males aged 20 years or older among the nationwide milk purchasing group. The subjects were 223 (41.9%) in the 20-29 year age group, 188 (35.3%) in the 30-49 year age group and 121(22.7%) in the over 50 year age group. The survey was conducted using ANOVA and multiple comparative analysis to examine the differences in age and multiple regression analysis was performed to investigate the factors affecting the intake of milk. Results: The intake of milk in the subjects was $538.14{\pm}494.23ml$ per week. There were statistically significant differences in the subjects' age according to processed milk, low fat, nonfat milk, cheese, and ice cream. The perception of milk and lactose and milk fat was recognized as a good food for skeletal health when milk was consumed. Among the milk nutrients, lactose was highly recognized at the age of 20-29, and milk fat was recognized in those over 50 years. In addition to lactose and milk fat, calcium was the most highly recognized among the milk nutrients. Health problems associated with milk were skeletal health, obesity, and lactose intolerance. The perception of lactose intolerance was related to lactose intolerance and fatness, and the dietary behavior was unaffected. Conclusions: This study examined the milk intake patterns of adult Korean males. Many variables were found to be related to the intake of milk. In this study, the milk intake was high when there was no problem with the perception and dietary behaviors of milk nutrition (lactose and milk fat). This study focused on lactose and milk fat, which are major nutrients in milk, and it is a new perspective study among milk-related research.

  • The purpose of this study was to analyze the relationship among medical students' learning motivation, characteristics of multiple intelligence, and academic achievement. The participants were 144 medical students. The data were collected by administering learning motivation tests (self-confidence, self-efficacy, level of task, emotion of learning, learning behavior, failure tolerance, task difficulty, and academic self-efficacy), a multiple intelligence test (linguistic intelligence, logical-mathematical intelligence, musical intelligence, bodily-kinesthetic intelligence, spatial intelligence, interpersonal intelligence, intrapersonal intelligence, and naturalistic intelligence), and two semesters of grades. There is a correlation between multiple intelligences and learning motivation. Among academic self-efficacy of academic motivation, the self-control efficacy (0.28) and behavior (0.18) subscales are significantly positively correlated with academic achievement. However, the emotion subscale (-0.18) was significantly negatively correlated. Learning motivation was correlated with two of the eight multiple intelligence profiles: the intrapersonal intelligence (0.18) and bodily-kinesthetic intelligence (-0.19). The structural equation modeling analysis showed that the behavior and self-control efficacy subscales of intrapersonal intelligence had an impact on academic achievement. An analysis according to the academic achievement group showed significant differences in self-control efficacy and emotion subscales with intrapersonal intelligence. A positive relationship can be observed between learning motivation and some characteristics of multiple intelligence of medical school students. In light of the findings, it is worth examining whether we can control medical students' learning motivation through educational programs targeting self-control efficacy and intrapersonal intelligence.

  • This paper reviewed the relationship between organizational justice and innovative behavior, and the moderating effect of gender. The results of multiple regression analysis, based on the responses from 412 employees in small business, showed that distributive justice, procedural justice and interactional justice have positive relationships with innovative behavior(process innovation, operation innovation, service innovation). In moderating effects, distributive justice more positively related with innovative behavior(process innovation and operation innovation) in male-group than in female-group. But interactional justice more positively related with innovative behavior(operation innovation and service innovation) in female-group than in male-group.

  • Purpose: This study aimed to evaluate the structural complexity of craniofacial trabecular bone in multiple myeloma by fractal analysis of panoramic and lateral skull radiography, and to compare the fractal dimension values of healthy patients (HPs), pre-treatment patients (PTPs), and patients during bisphosphonate treatment (DTPs). Materials and Methods: Pairs of digital panoramic and lateral skull radiographs of 84 PTPs and 72 DTPs were selected. After application of exclusion criteria, 43 panoramic and 84 lateral skull radiographs of PTPs, 56 panoramic and 72 lateral skull radiographs of DTPs, and 99 panoramic radiographs of age- and sex-matched HPs were selected. The fractal dimension values from panoramic radiographs were compared among HPs, PTPs, and DTPs and between anatomical locations within patient groups using analysis of variance with the Tukey test. Fractal dimension values from lateral skull radiographs were compared between PTPs and DTPs using the Student t-test. Pearson correlation coefficients were used to assess the relationship between the mandible from panoramic radiographs and the skull from lateral skull radiographs. Intra-examiner agreement was assessed using intraclass correlation coefficients (α=0.05). Results: The fractal dimension values were not significantly different among HPs, PTPs, and DTPs on panoramic radiographs or between PTPs and DTPs on lateral skull radiographs (P>0.05). The mandibular body presented the highest fractal dimension values (P≤0.05). The fractal dimension values of the mandible and skull in PTPs and DTPs were not correlated. Conclusion: Fractal analysis was not sensitive for distinguishing craniofacial trabecular bone complexity in multiple myeloma patients using panoramic and lateral skull radiography.
