PURPOSE: To determine whether triple negative (TN) early stage breast cancers have poorer survival rates compared with other molecular types. MATERIALS AND METHODS: Between August 2000 and July 2006, patients diagnosed with stage I, II early stage breast cancers, in whom all three markers (estrogen receptor, progesterone receptor, and human epidermal growth factor receptor [HER]-2) were available and treated with modified radical mastectomy or breast conserving surgery followed by radiotherapy, were retrospectively reviewed. RESULTS: Of 446 patients, 94 (21.1%) were classified as TN, 57 (12.8%) as HER-2 type, and 295 (66.1%) as luminal. TN was more frequently associated with young patients younger than 35 years old (p = 0.002), higher histologic grade (p < 0.0001), and nuclear (p < 0.0001). The median follow-up period was 78 months (range, 4 to 130 months). There were 9 local relapses (2.0%), 15 nodal (3.4%), 40 distant metastases (9.0%), and 33 deaths (7.4%) for all patients. The rates of 5-year OS, DFS, LFS, and DMFS for all patients were 95.5%, 89.9%, 95.4%, and 91.7%, respectively. There were no significant differences in OS, DFS, LFS, and DMFS between triple negative and other subtypes (p > 0.05). CONCLUSION: We found that patients with TN early stage breast cancers had no difference in survival rates compared with other molecular subtypes. Prospective study in homogeneous treatment group will need for a prognosis of TN early stage breast cancer.

PURPOSE: The purpose of this study was to compare the relationships among parent-child communication, self-esteem and sexual assertiveness for male and female university students. METHODS: This descriptive study used a comparative survey design that utilized self-report questionnaires. A total of 470 participants were male and female university students in B metropolitan city. RESULTS: The degree of open communication use was higher for female students in comparison to male students, There were no differences in dysfunctional communication for both the father-child communication. There were no differences between males and females for the mother-child communication either. The degree of self-esteem was higher for male students in comparison to the female students. The degree of sexual assertiveness was higher for female students in comparison to the male students. The grade, religion, major, allowance source, marital status of parents, and relationship experience with opposite sex were influencing factors for the male students' sexual assertiveness whereas the individual's major and physical contact were influencing factors for the female students. CONCLUSION: Self-esteem and mother-child open communication were influencing factors of sexual assertiveness. Thus, the nursing intervention based on the influencing factors is needed in order for male and female students to express sexual assertiveness.

PURPOSE: The aim of this study was to evaluate the clinical manifestations, contact history, and status of tuberculosis contact investigations in school-age children and adolescents with pulmonary tuberculosis (TB) at two centers. METHODS: This study was conducted with 54 patients in the age ranging from 10 to 18 years, who were diagnosed with pulmonary TB at the Pusan National University Hospital and Pusan National University Children's Hospital, January 2008 to December 2012. We retrospectively reviewed the medical records of the patients. RESULTS: The median age of the patients was 16 years old; 11 patients were aged 10 to 14 and 43 patients were aged 15 to 18. Among 54 patients, 19 had history of contact with pulmonary TB, 10 had contact with house members (household), and remaining 9 had contact with classmates (non-household). One out of 10 patients who had household contacts and 6 out of 9 patients who had non-household contacts were evaluated with contact investigation after the exposure to pulmonary TB. Among 7 patients who were evaluated with contact investigation, 3 were diagnosed with active pulmonary TB, 1 had latent tuberculosis infection (LTBI), and 3 had no evidence of TB or LTBI. The median period of diagnosis after the exposure to active pulmonary TB was 2 years in patients with household contacts and 0.23 years in patients with non-household contacts. CONCLUSION: This study suggested that if the contact investigation conducted properly, it would be helpful for early diagnosis and prevention of pulmonary TB.

Heat shock protein of 72 kDa (HSP70) has a role in the functional modulation of sex steroid hormone receptors and in p53-associated oncogenesis and inhibits apoptosis associated with bcl-2. However, the exact role of HSP70 in the development of endometrial adenocarcinoma has not been well established. The aim of this study is to evaluate the role of HSP70 in relation with ER, PR, p53 and bcl-2 expressions and apoptosis in benign and malignant endometrial lesions. Immunohistochemical studies for HSP70, ER, PR, p53, bcl-2 and TUNEL method for apoptosis were performed in 30 cases of adenocarcinoma and 30 cases of benign endometrial lesions consisted of each 10 cases of disordered proliferative endometrium (DP), simple or complex hyperplasia (HP), and atypical hyperplasia (AH). There were no significant differences of HSP70 and bcl-2 expression rates and apoptotic index (AI) between DP, HP, AH, and adenocarcinoma. p53 expression rate in adenocarcinoma was 36.7%, but no p53 expression was identified in DP, HP and AH (p<0.05). In adenocarcinoma, HSP70 expression rate was higher in ER and PR negative adenocarcinoma (p<0.05), and p53 expression rate was higher in nonendometrioid type and FIGO grade II and III (p<0.05), but no significant difference of bcl-2 expression rate according to the histological type and FIGO grade. AI was higher in nonendometrioid type (p<0.05). There was no correlation between HSP70, p53 and bcl-2 expressions, and no significant difference of AI according to HSP70, ER, PR, p53, and bcl-2 expressions. In conclusion, higher HSP70 expression rate in poorly differentiated and ER and PR negative adenocarcinoma suggests that HSP70 inhibits ER and PR expression and may be involved in the development of poorly differentiated endometrial adenocarcinoma.

Background: Dental hygienists study dental radiology through the dental hygiene department and curriculum, and most of the radiography work in dental clinics is performed by dental hygienists; however, the legal work regulations for dental hygienists place restrictions on the type of radiography performed. This study aimed to identify the actual conditions of the radiographic work performed by dental hygienists and to determine the difference according to the type of hospital. Methods: This study included 195 dental hygienists working at dental medical institutions in the metropolitan area. A survey was conducted on regarding the radiographic work performed and the clinical career of the main performers. The radiography work was divided into periapical radiography, bite-wing radiography, occlusal radiography, panoramic radiography, computed tomography (CT), and cephalometric radiography. Results: The frequency of performing intraoral radiography was as follows: periapical radiography, 94.9%; bite-wing radiography, 93.8%; and occlusal radiography, 77.9%. The frequency of performing extraoral radiography was 94.4% for panoramic radiography, 89.7% for CT, and 73.3% for cephalometric radiography. The frequency of internal and external radiography performance was higher among hygienists in dental clinics than among those in dental hospitals and university hospitals. The analysis of the dental hygienists’ clinical experience in the areas of intraoral and extraoral radiography showed that those working at university hospitals, dental hospitals, and dental clinics had over 5 years, 2∼4 years, and 1 year of clinical experience, respectively. The hygienists with less than 1 year of clinical experience showed high performance frequency (p<0.05). Conclusion For the dental hygienists to perform radiography safely, a discussion regarding the revision of related laws and regulations is warranted.

Background: The purpose of this study was to confirm the major motivation for and self-efficacy of career decisions among dental hygiene students and to analyze differences in career decision self-efficacy according to the major motivation. Methods: An online survey was conducted among 194 dental hygiene students. To investigate career decision self-efficacy, 18 questions were posed, including 5 questions on future planning, 4 questions on self-evaluation, 4 questions on job information collection, 3 questions on goal setting, and 2 questions on problem solving. The survey was conducted using a 5-point scale. Results: The motives for choosing a major were a high employment rate (68.6%), a desire to become a professional (36.1%), according to aptitude (27.8%), recommendations by others (26.3%), and according to grades (12.9%). The career decision self-efficacy of the study participants was in the order of self-evaluation factors (3.75 points), problem solving factors a (3.62 points), job information collection factors (3.59 points), future planning factors (3.46 points), goal setting factors (3.44 points) score was high. The career decision self-efficacy scores were higher when the major motivation was “because I want to become a professional” and “because I think I have an aptitude for it.” Conclusion It is necessary to give students who wish to major in dental hygiene an opportunity to consider whether they have an aptitude for it by providing information on not only major subjects but also the duties and roles of dental hygienists. In addition, it is necessary to develop a career education program to help dental hygiene students set their career goals.

Background: This study aims to investigate the perceptions of dentists and dental hygienists regarding quality dental jobconditions and to identify differences in perceptions based on job type. Methods: As a result of conducting face-to-face and online surveys, data from a total of 132 people were analyzed. In order toinvestigate the perception of quality job conditions, the importance of a total of 13 items was investigated, and the work policies and job satisfaction of the current workplace were examined. Since the data did not follow a normal distribution, a non-parametric test, the Mann–Whitney U test, was performed. Results: Both dentists and dental hygienists perceived income and working hours to be of priority importance for quality jobconditions. Dental hygienists valued holiday support and welfare, human relations, and personal development potential more than dentists (p＜0.05). Looking at differences by job type, dental hygienists rated all conditions as more important than dentists except income, indicating a statistically significant difference (p＜0.05). In terms of the work policies, 96.2% of the practices in the study were required to have the four types of social security contributions, but fewer had flexible working hours (19.7%), healthcare support (23.5%), and incentives (25.0%). Of the participants, 60.6% had parental leave available at their workplace, and dental hygienists had statistically significantly higher job satisfaction when parental leave was available (2.57 points) than when it was not (p＜0.05). Conclusion Quality dental jobs are an important factor in keeping workers happy and maintaining an efficient practice. Dentalpractice owners need to pay attention to the quality of jobs required by the dental workforce, provide flexible working hours and welfare programs such as parental leave, and create a workplace atmosphere and human resource management system that supports the use of these programs.

PURPOSE: The study was done to examine the effects of cognition-behavior integrated breast cancer prevention education, in which a breast model with interchangeable nodules was utilized, on the self-competency of nursing students in performing breast cancer education. METHODS: A nonequivalent control group non-synchronized design was used. A traditional lecture intervention was provided for 49 3rd year college of nursing students (control group) while the integrated breast cancer prevention education was given to 47 3rd year students in the same college one year later (experimental group). The integrated breast cancer prevention education was developed by the research team to strengthen the competency of cognitive and behavioral components in education on breast cancer. RESULTS: Effects of the intervention were found to be significant through all study variables: knowledge about breast cancer (t=7.79, p <.001), breast cancer risk awareness (t=2.05, p <.05), self-competency of breast self-exam (t=8.27, p <.001), and intention to teach breast self-exam (t=3.87, p <.001). CONCLUSION: The integrated breast cancer prevention education was useful to improve not only knowledge about breast cancer but competency in performing breast examination for nursing students who acquired technical skills from various simulation nodules. As the program helped the students to be prepared as confident educators, future application of the module is recommended for academic curricula.

PURPOSE: Food intake of COPD patients decreases because of appetite loss, depression, and breathing problems while eating, which increase the likelihood of patients becoming malnourished. This study investigated the nutrient intake and dietary quality of people with and without COPD in Korea. METHODS: There were 2,160 adults aged 50 and over who participated in the 5~6th Korea National Health and Nutrition Examination Survey. The subjects were divided into the COPD group and non-COPD group according to the rate of forced expiratory volume at 1 second (FEV1) against forced vital capacity (FVC). Consumption of food and nutrients were calculated based on the nutrition examination survey. Statistical analyses were conducted using SPSS 19.0. RESULTS: Among individuals in their 50s, intake of vitamin B1 in the COPD group was significantly less than the NCOPD group, while intake of sodium in the COPD group was significantly greater than the NCOPD group. Among individuals in their 60s, the energy intake of the COPD group was significantly less than that of the NCOPD group. The COPD group showed significantly less intake of vitamin B1 and vitamin C, but greater intake of sodium than the NCOPD group. In the group aged 70 and over, The COPD group had significantly less intake of vitamin B1 than the NCOPD group and showed lower nutrient adequacy ratio values in protein, vitamin B1, vitamin B2, and iron than the NCOPD group. CONCLUSION: The COPD group consumed less energy and certain nutrients, and their dietary quality was poor compared to the NCOPD group. Thus, more detailed research is required to understand the concrete relationship between COPD and malnutrition.
