Purpose: The aim of this study was to determine the predictive factors for maternal role development for mothers of premature infants. Methods: A descriptive correlational study was conducted. A total sample of 121 mothers of premature infants following discharge from the neonatal intensive care unit were recruited using two strategies; an internet-based survey and an in-person data collection in a tertiary university hospital in Korea. A self-report questionnaire was used to collect data regarding personal, birth variables, marital intimacy, maternal attachment, maternal identity and maternal role development. Results: A hierarchical multiple regression analysis indicated that parity, maternal attachment, marital intimacy and maternal identity were predictors for maternal role development for mothers of premature infants, accounting for 70% of the variance. Among these variables, maternal attachment is the most powerful predictor for maternal role development. Conclusion: Nursing interventions during hospitalization to post-discharge education that includes parents of premature babies with positive interaction between couples strengthening marital intimacy and promotes maternal attachment that leads to integrate maternal identity should be considered by priority. Community-based family services such as home visits should be focused on maximizing the predictive factors for maternal role development in transition to motherhood that can contribute to maternal health as well as optimal growth and development of premature infants.

Purpose: This study was aimed to identify the influencing factors on the quality of life among breast cancer survivors. Methods: The subjects were 159 female patients who visited out-patient department (OPD) after the mass removal surgery for breast cancer and had completed adjuvant treatments such as chemotherapy, radiation therapy at a university hospital and a general hospital. Data collection was conducted using the Ferrell QOL scale, the Mishel uncertainty scale, the Fitts & Osgoods body image scale revised by Jeon & Kim. the Rosenberg self-esteem scale, and the Kang family support scale. Results: The level of QOL in the participants was in the middle. There were a significant correlation between QOL, uncertainty, self-esteem, and family support. There were significant differences in QOL with the perceived health condition and the best support person. In a regression analysis, the most powerful predictor of QOL was body image (21.7%). Altogether uncertainty and perceived health condition explained 28.6% of the variance of QOL of the participants. Conclusion: Body image, uncertainty, and perceived health condition were important predictors of QOL. These results demonstrated the need for developing interventions to improve QOL of breast cancer survivors.

Objective: This paper investigates gait changes according to different heel heights and speeds, and the interaction between the effects of the heel height and the speed during walking on stride parameters and joint angles. Furthermore, the relationship among heel height, speed and gait variables is investigated using linear regression. Background: Gait changes by heel height or speed have been studied respectively, but has not been reported whether there is an interaction effect between heel height and speed. It would be necessary to understand how gait changes when a person wears heels in different heights at various speeds, for example, high-heeled walking at fast speed, since it may cause unusual gait patterns and musculoskeletal disorders. Method: Ten females were asked to walk at five fixed cadences (94, 106, 118, 130 and 142 steps/min.) wearing three shoes with different heel heights (1, 5.4 and 9.8cm). Nineteen gait variables were analyzed for stride parameters and joint angles using two-way repeated measure analysis of variance and regression analysis. Results: Both heel height and speed affect movement of ankle, knee, spine and elbow joint, as well as stride length and Double/Single support time ratio. However, there is no significant interaction effect between heel height and speed. The regression result shows linear relationships of gait variables with heel height and speed. Conclusion: Heel height and speed independently affect stride parameters and joint angles without a significant interaction, so the gait variables are linearly amplified or diminished by the two factors. Application: Walking in high heels at fast speed should be careful for musculoskeletal disorders, since the amplified movement of knee and spine joint can lead to increased moment. Also, the result might give insight for animators or engineers to generate walking motion with high heels at various speeds.

This study aims to analyze a selective examination for the gifted and talented from a domain-general and special standpoint. For this, we analyzed gifted and talented test results carried out by Gifted and Talented Education institute affiliated with the university of Education located in the central region of South Korea. This test consisted of three sections which are giftedness in the first round, academic aptitude in the second round and interview in the last round. I conducted the analysis of variance of the giftedness test result to the gifted and talented group in each subject from the domain-general point of view. As a result, the each group was not significant. This means that the gifted and talented in each subject has giftedness from the domain-general viewpoint. Secondly, I implemented the analysis of correlation among three test such as giftedness, academic aptitude and interview conducted during the selective process for the gifted and talented. The result was that they had a low or no correlations between them and were not significant. This demonstrated that each test checked a different area. That is, we came to realize that the first, second and third test evaluates a different area and in particular, with the result that the first and second test had a low or no correlations between both of them we realized that they evaluated a different area from a domain-special standpoint. The purpose of this study is meaningful to investigate in terms of how the selective test for the gifted and talented is conducted from a domain-general and special standpoint as a recent study viewpoint about the gifted and talented along with creativity. It is too limited to generalize this result because this test was sampled by one region but, this study indicates that we should take a domain-general and special standpoint into account when it comes to selection for the gifted and talented.

교통수요 예측 모델에서 통행을 기본 단위로 사용하는 4-단계 통행기반 모형은 오랜 시간동안 광범위하게 사용되어 왔으나, 최근 교통수요예측의 결과가 차량 개통 후 실제 교통량과 차이가 크게 발생되어, 예측 결과에 대한 불신이 증가되고 있다. 이러한 교통량 예측의 차이는 인간의 자연스러운 통행활동을 모형 개발 단계에서 고려하지 않기 때문이다. 그러나 미국에서는 교통수요예측의 정확성과 현실성을 높이기 위해 활동기반 모형을 1990년대 부터 활발하게 연구 및 개발하여 점진적으로 기존 4-단계 통행기반 모형을 대체하고 있는 상황이다. 본 논문은 통행기반 모형과 활동기반 모형을 분석단위, 분석절차, 문제점 등을 상호 비교 검토하는데 목적을 두었다. 기존의 교통수요예측 방법론의 문제점을 진단하기 위해, 미국을 중심으로 대표적인 세 가지 활동기반 모형 시스템(DaySim, CT-Ramp, CEMDAP)을 사용하였다. 통행기반 모형은 인간의 다차원적인 통행의사 결정 과정을 효율적으로 쉽게 설명할 수 있으며, 이는 교통수요 예측의 정확성을 한층 더 높일 수 있을 것으로 판단된다. 따라서, 우리나라도 수요예측의 현실성과 정확도를 높이기 위해 인간의 활동을 기반으로 보완, 개선된 수요예측방법론이 검토되어야 한다.

The purpose of this study was to compare the validity of obese index among body mass index (BMI), waist to hip ratio (WHR), and waist circumference (WC) and to determine which is the best in relation to cardiovascular disease (CVD) risk in Korean elderly more than 65 ages. Data from the 1998 Korean Health and Nutrition Survey were used (n=1017). Anthropometric indices and CVD risk factors were measured, and chi-square test, analysis of variance following duncan's multiple range test, partial correlation analysis, and Receiver Operator Characteristic (ROC) curves were used in the analysis. Anthropometric values were decreased in both male and female when ages were goes up. In female elderly, it specially showed the characteristics of upper body fat and systolic blood pressure risk (p<0.05). Among life style factors the current smokers were prevalent in obese male (p<0.05), but not prevalent in female having obese or upper body fat. Also, person with upper body obesity have more exercise than that of normal group (p<0.01). Mean BMI values of the current smoker was lower than that of normal group in both sexes (p<0.01). Mean BMI value of person with other risk factors were higher than that of normal groups (p<0.05). Among 7 CVD risk factors in partial correlation analysis, WC had the highest correlation coefficient in 5 in male, whereas BMI in 4 in female. In ROC analyses of 12 risk factors and health conditions, the largest area under curve of obese indices for risk factors were WC>WHR>BMI in male and BMI>WHR>WC in female. The optimal cutoff values of each index (BMI : WHR : WC) for one or more risk factors were 19.02 : 0.84 : 71.3 in male and 19.04 : 0.88 : 85.6 in female. In conclusion, Most Korean elderly showed non-obese and abdominal obesity likewise other Asians. Also CVD risk factors were prevalent in Korean elderly within normal limits of obese indices. Therefore the upper body fat indices reflected in the aged whose muscle mass is replaced by fat must be used as an indicator of CVD risk together with BMI. Although WHR was the worst index based on partial correlation analysis and so located between BMI and WC in ROC curve analysis in both sexes, it need to be use with WC to screen the cardiovascular risk group.

This study was also to analyze brand image and consumer's seeking image. The 660 questionnaires were distributed and 618 reliable ones were used for statistical analysis. A SAS statistical package including frequency table, Chi-square test, factor analysis, analysis of variance(ANOVA), Duncan's multiple range test and paired-t test was used. The results are as follows: 1. Brand awareness involves "brand recall" based on asking a person to name the brand recalled first, and "brand recognition" based on asking to identify brand name from 30 given brands. The result of recall brand test indicated that Levi's was dominant brand. People recognized about 70.8% of brands on the average. Brand recognition was influenced by segmented distribution region and demographic variables. 2. There was significantly positive relationship between brand recognition and purchasing behavior. 3. National brands were more recognized than Licensed brands. 4. The result showed that "Nix" was best represented for sophisticated brand image, "Strom" for characteristic, "Jambangee" for resonable price, and "Levi's" for classic '||'&'||' comfortable brand image. 5. As a result of factor analysis on consumer's seeking image, six factors(characteristic, young, intelligent/sexy, comfortable, exotic and popular) were found. Several factors had a relationship with preferred design, demographic variables, fashion interest, and brand recognition. variables, fashion interest, and brand recognition.

This study investigates the buying behavior of apparel by middle aged women according to lifestyles. Questionnaires were distributed to 300 women who lived in the Seoul area and between 40 to 65 years of age. A sample of 248 women responded. To analyze the data, Factor Analysis, Cluster Analysis, Analysis of Variance (ANOVA) and a Duncan test were used. As a result, the respondents were clustered into 4 different groups according to lifestyles. The groups included practical oriented group, economic oriented and practical group, active oriented and appearance group, and economic group. Their buying behavior was as follows. First, the active oriented and appearance group shopped at department stores and specialty stores; however, the economic oriented and practical group shopped at discount stores more often than other groups. The practical group shopped more frequently using TV home shopping networks, discount stores, and outlet stores, the economic group shopped at off-price stores, discount stores, and online more than the other groups. Second, the active oriented and appearance group bought classic suits and semi-classic suits, imported brand and/or designer brand apparel more often than other groups. Third, the active oriented and appearance group perceived another person's appearance, advertisement, and shop display as a more important information source than other groups. Forth, the active oriented and appearance group considered design & style, harmony with self-image, brand name, color, and coordination with other clothing as more important selection factors for clothing than other groups. The economic groups considered coordination with other clothing; however, the economic oriented and practical group cited ease of care as more important factors.
