  • The development of breast implant technology continues to evolve over time, but changes in breast shape after implantation have not been fully elucidated. Thus, we performed computerized finite element analysis in order to better understand the trajectory of changes and stress variation after breast implantation. The finite element analysis of changes in breast shape involved two components: a static analysis of the position where the implant is inserted, and a dynamic analysis of the downward pressure applied in the direction of gravity during physical activity. Through this finite element analysis, in terms of extrinsic changes, it was found that the dimensions of the breast implant and the position of the top-point did not directly correspond to the trajectory of changes in the breast after implantation. In addition, in terms of internal changes, static and dynamic analysis showed that implants with a lower top-point led to an increased amount of stress applied to the lower thorax. The maximum stress values were 1.6 to 2 times larger in the dynamic analysis than in the static analysis. This finding has important implications for plastic surgeons who are concerned with long-term changes or side effects, such as bottoming-out, after anatomic implant placement.

  • Purpose: The purpose of this study was to develop an antepartum-postpartum breast-feeding program titled "Breastfeeding Empowerment Program" and to measure the effects of this program on breast-feeding empowerment and the rate of exclusive breast-feeding. Methods: The study design was a nonequivalent control group design with repeated measures. Results: The scores for breast-feeding empowerment of the experimental group (EG) were higher than those of the control group (CG) at week 1, 4, 8, 12. The rates for exclusive breast-feeding of the experimental group were also higher than those of the control group: 86.4% in the EG and 40.9% in the CG at week 1; 100% vs 42.9% at week 4; 86.4% vs 38.1% at week 8; 95.5% vs 38.1% at week 12; 94.7% vs 31.6% at 6 months; 89.5% vs 26.3% at 12 months. Conclusion: The study provided evidence that raising consciousness and strengthening mother's will and skills for exclusive breast-feeding helps them to achieve successful breast-feeding by themselves. In addition mothers need to be empowered to breastfeed starting before delivery and continuing after delivery. This approach could make long-term exclusive breast-feeding successful.

  • Purpose: In this study the effects of breast massage on breast pain, breast-milk sodium, and newborn suckling in early postpartum mothers were investigated. Methods: The design was a non-synchronized nonequivalent control group pretest-post-test design. Sixty postpartum mothers who were admitted to a postpartum care center and had problems with breastfeeding were recruited. Of these mothers, 44 were assigned to the intervention group and received two 30-minute breast massages within 10 days of postpartum period. The others were assigned control group and received only routine care. Breast pain was measured using a numeric pain scale and number of times newborns suckled was observed throughout breastfeeding. Breast milk was self-collected to evaluate breast-milk sodium. Results: Mean age of postpartum mothers was 30 years old. Compared to the control group, women in the intervention group reported significant decreases in breast pain (p<.001), increases in number of times newborns suckled after the first and second massage (p<.001), and a decrease in breast-milk sodium after the first massage (p=.034). Conclusion: Breast massage may have effects on relieving breast pain, decreasing breast-milk sodium, and improving newborn suckling. Breast massage can be used to solve breast problems. Further research is needed to validate our findings.

  • This study investigates the breast cathexis and brassiere design preferences of Chinese citizens living in Hong Kong in order to provide marketing intelligence for bra manufacturers whose target customers are from this group of potential customers. A questionnaire composed of questions concerning breast shape evaluations, brassiere design preferences, and brassiere purchase and wear practices was administered to 165 Hong Kong Chinese female undergraduates(N=165). For an analysis of our data, we used the SPSS program(version 14.0). The results indicate that a majority of Hong Kong Chinese female undergraduates perceive their breasts as 'slightly smaller than normal' (n=59, 35.8%) or 'normal'(n=78, 47.3%) in volume, and 'conical'(n=77, 46.7%) or 'flat'(n=46, 27.9%). The results also suggest that Hong Kong Chinese women possess positive breast cathexis, with only a third of the respondents reporting dissatisfaction with their breasts. Women with dome-shaped breasts expressed the most positive breast cathexis, followed by those with cone-shaped breasts. The results also show that Hong Kong Chinese typically purchase 2 brassieres per year, which is a lower purchasing rate than their counterparts in Korea(Cha & Sohn, 2010) and Taiwan(ICT Life Style Research Center, 2004). The findings also demonstrate that the preferred brassiere color is black(57%), unlike in Korea, where women prefer skin-colored brassieres.

  • The study surveyed patients undergoing a mastectomy to understand their experience and requirements on artificial breasts and sales status. We retrieved 149 of the 150 surveyed questionnaires; subsequently, 144 questionnaires, excluding missing values, were used in the analysis. According to the results of the study, about 67% of respondents said that artificial breasts were not used after undergoing a mastectomy, and more than half of the breast cancer patients were not aware of the importance of artificial breasts. Breast cancer patients wearing artificial breast felt uncomfortable and hot during daily activities as well as experienced difficulty in size selection and purchase price burdens. The three most responded brands were selected based on the results of the survey that also investigated the sales status of the commercial artificial breast. Company A was selling artificial breast to reflect the consumer's functional requirements, and Company C was selling artificial breast with various kinds of reduced weight. However, it is thought that consumers will have less choice since artificial breasts have more limited forms than various types. Therefore, it is believed that the patient needs artificial breasts that satisfy the shape of various types of mastectomy. This study can be used as basic data for artificial breast development studies.

  • Preservation of the breast skin envelope during immediate implant-based breast reconstruction is important for producing symmetrical and natural-looking breasts. We propose the lazy S design for the closure of round-shaped wounds with the hope of improving the aesthetic outcomes and reducing the tension on the wound by preserving the skin. Additionally, the direction of tension is dispersed due to the shape of this design. Patients undergoing implant reconstruction after skin-sparing mastectomy may benefit from the lazy S design.

  • This study investigates changes in body size (as well as fit) before/after wear, according to the breast and brassiere type. To offer producers basic data on how to develop excellent brassieres, we accordingly conducted preliminary research on 183 20's women. The research revealed that breast-related size and fit change by about 10%; however, the upper length and inner length of breasts decreases. The fit of domed ones is the best and the fit of the elongated ones is the worst; subsequently, a closer representation of the ideal breast leads to a better fit to wear.

  • We performed an assessment of wearing, purchasing, satisfaction, and the fit of brassieres according to body and breast type for college women to provide basic data on the manufacture of an ergonomic brassiere. The classifications of domed and conical breast type or projecting and conical breast type were unclear. Flat breast were dissatisfied with the shape of small and flat, and drooping breast were dissatisfied with the shape of big, projected, and drooping. In purchasing a brassiere, the majority of subjects were ignorant of their brassiere size, and over 80% of the subjects bought a brassiere without trying it on. Over 50% of those surveyed said they found it difficult to buy a well-fitted brassiere, particularly for the flat and drooping breast type. Over 70% of those surveyed wore a brassiere of 3/4 cup size, the slim body type wore a brassiere of 1/2 cup size; however, the obese body type wore a brassiere of full-cup size. The flat-breast or slim-body wore a brassiere of a thick pad type but projecting-breast or drooping breast wore brassiere of a thin pad type. Many of the subjects wore an unfitted brassiere in cup size and under bust size. In the classification of breast type, there were slight differences between the breast type that they recognized and the breast type that they were shown. There were distinctions in function, satisfaction, and fitness based on breast type. Therefore, the development of an ergonomic brassiere should considered the characteristics of breast type for fitness and comfort.

  • Breast self-examination is the most effective and easiest way for women to increase the responsible consciousness about their health. The purpose of this study was to test the variables impacted to promote breast self-examination practice. The research design used in this study was a nonequevalent control group of a non-synchronized design. The sample that was assembled consisted of 124 women. A purposive sample consisted of 124 women. Each subject was given to assessed on the following the demographic data related to the breast self-examination, knowledge of self-examination, accuracy, in performing self-examination, self-efficacy about breast cancer and breast self-examination, and the number of subjects who found a mass. The result of this study may be summarized as follows : 1. To examine the theretical model fit to the data, chi square test statistics and goodness of fit index were identified($\chi$$^2$=2.30, df=2, GFI=0.99, AGFI=0.94 RMSR=0.02, NFI=0.99, NNFI=0.99, Critical Number=439). 2. The direct effects of education of breast self-examination were knowledge, self-efficacy, accuracy, number finding a mass. But the Indirect effect of education on breast self-examination was frequency of breast self-examination. 3. Knowlege, as direct paths to the breast self-examination practices, was removed in the theoretical model. The parsimonious best fit model included self-efficacy, accuracy, the number finding mass, frequency of breast self-examination practices. 4. The final model produced a chi-square=5.58(p=0.35) with df=5, and GFI =0.99, AGFI =0.94, RMSR=0.03, NFI=0.99, NNFI=0.99, CN=339 indicating very a good fit. Based on the result of this study, education of breast self-examination is very effective for increasing the competency of the breast self-examination through the knowledge and self-efficacy. Resources to promote self-efficacy may be helpful to increase the frequency of self-examination because self-efficacy is a direct effect on it. These findings suggest the need to develop nursing strategy to promote the self-efficacy of breast self-examination.
