Objective : This research was designed to study the characteristics of heart rate variability in postpartum women compared with normal women. Method : HRV data of postpartum women were gathered from 255 women who was hospitalized for oriental postpartum treatments(Age : 25-35). HRV data of comparision group were gathered from 327 women who visited hospital to check up their health(Age : 25-35). The SPSS 12.0 for windows was used to analyze the date and the independent samples t-test was used to verify the result. Result :1. Mean-RR and SDNN of postpartum women group significantly decreased compared with that of normal women group. But, Heart Rate of postpartum women group significantly increased compared with that of normal women group. 2. HRV-Index, RMSSD and SDSD of postpartum women group significantly decreased compared with that of normal women group. pNN50 of postpartum women group significantly increased compared with that of normal women group.3. Ln(TP), Ln(VLF), Ln(LF) and Ln(HF) of postpartum women group significantly increased compared with that of normal women group.4. There were no significant differences in Normal LF, Normal HF and LF/HF Ratio between postpartum women group and normal women group. Conclusion : The result suggest that the function of heart of postpartum women group significantly decreased compared with that of normal women group. Futhermore although the ANS maintained the balance in the range of normality, the sympathetic nervous system frequently revitalized which caused increasing the heart of pulsation.

본 연구는 장기적인 브랜드 관리에 있어서 브랜드 에쿼티 구축을 위한 브랜드 구성요소 중 패키지를 선택하여 장수 브랜드 활성화 시 리뉴얼을 위한 패키지 특성인자(特性因子) 추출에 목적이 있다. 패키지 특성인자가 존재하며, 패키지 특성인자 변경 시 브랜드 에쿼티에 영향을 미치고, 장수제품도 리뉴얼이 가능한 특성인자가 있다는 가설을 설정하였다. 연구가설의 검증을 위해 장수 제품의 패키지 구성요소를 화상 변경하여 실험 조사하였다. 조사 결과 패키지 에쿼티를 명확하게 파악할 수 있었다. 이를 토대로 노후화된 이미지의 개선, 새로운 이미지의 추가, 혁신적인 리뉴얼로 부가적인 가치 창출을 통해 장수제품의 브랜드 활성화 방안을 연구하였다. 연구방법에는 장수 브랜드(빙그레 바나나 맛 우유)의 독립변수에 해당하는 패키지 화상스왑을 자극변인으로 투입하여 종속변수에 해당하는 브랜드 인지, 이미지, 품질, 로열티의 BPI 측정값을 패키지 특성인자별로 각각 산출하였다. 연구결과로는 장수제품의 패키지 특성인자는 명확히 존재하고, 특성인자 변경 시 브랜드 에쿼티에 미치는 영향은 크다는 사실을 확인할 수 있었고, 리뉴얼 시 변경 가능한 특성인자가 추출 되었다. 또 패키지 특성인자 추출에 필요한 모델이 구축되었다. 현장과 이론에 실제적 적용을 위한 시사점은 제품 출시 후 브랜드의 장수는 곧 기업 브랜드 경영의 목표로 귀결 될 것이다. 장수제품 리뉴얼 시 패키지 특성인자 추출모델을 적용하여 장수 브랜드 리뉴얼 시 그 범위를 선정할 수 있다. 장수 브랜드화를 위한 브랜드 활성화 시 필요한 패키지 특성인자 추출모델을 제안 하였다. This study of longevity in terms of brand management, brand activation factor renewal properties for the package is intended to extract. By the presence of package characteristics, and package characteristics change factors affecting brand equity, long life characteristics of products that can be renewed by the hypothesis that was set. Research to validate the hypothesis of longevity and video components of the product by changing the package was an experimental investigation. Equity survey package was determined to clarify. Based on this image of aging improvements, adding new images, and innovative renewal through the creation of added value to the longevity of the product were studied ways to activate the brand. How to research the longevity product (Binggrae banana flavored milk) of the independent variables corresponding to the variables introduced to the stimulus package, image swap, corresponding to the dependent variable, brand awareness, image, quality, loyalty and package characteristics of the BPI measures calculated for each of the argument was Packaged in a longevity study characteristics clearly present the arguments and change the attributes argument greater impact on brand equity that can be changed at renewal were able to determine the characteristics of been a self-extracting. The package model is needed to extract characteristic parameters have been established. Field theory and the implications for practical applications in the market shortly after the brand's longevity will result in the goals of corporate brand management. Renewal of longevity for the product package Characteristics of longevity products by applying the factor extraction model can select the new range at renewal. Longevity for the brand branding package characteristics required for activation of factor extraction model is proposed. Finally, the study's limitations and realistic constraints that did not deal with a variety of brands in the direction of future research suggested.
Estimation for misclassified data with ultra-high levels

Outcome misclassification is widespread in classification problems, but methods to account for it are rarely used. In this paper, the problem of inference with misclassified multinomial logit data with a large number of multinomial parameters is addressed. We have had a significant swell of interest in the development of novel methods to infer misclassified data. One simulation study is shown regarding how seriously misclassification issue occurs if the number of categories increase. Then, using the group lasso regression, we will show how the best model should be fitted for that kind of multinomial regression problems comprehensively.
