Purpose: The purpose of this study was to analyze periodic screening behaviors for breast cancer and factors affecting the screening behaviors among hospital nurses. Methods: A total of 461 nurses were recruited from 15 hospitals located in two southern areas of Korea. The Champion's Health Beliefs Model Scale-Korean version and a structured study questionnaire were used for data collection. Data were collected during July and August 2008. Results: Nurses who performed periodic mammography accounted for 15.6% of the total, while 22.8% performed periodic breast self-examination (BSE). Among married nurses, the rates of periodic mammography and BSE were significantly different by age, menopausal status, delivery experience, family history of breast cancer, and experiences of cervical cancer screening. Significant factors affecting periodic mammography were family history of breast cancer, experiences of cervical cancer screening, age above 40, and performance of periodic BSE. For health beliefs, levels of severity, confidentiality and barrier were significant factors for periodic BSE. Conclusion: Nurses, who are role models for health promoting behaviors, did not adequately performing periodic BSE and mammography. A health promotion program for breast cancer designed for hospital nurses is needed to improve performance rates for periodic screening behaviors for breast cancer.

By development of renewable energy and more efficient facilities in an increasingly deregulated electricity market, the operation cost of distributed generation (DG) is becoming more competitive. International environmental regulations of the leaking carbon become effective to reinforce global efforts for a low-carbon paradigm. Through increased DG, operators of DG are able to supply electric power to customers who are connected directly to DG as well as loads that are connected to entire network. In this situation, a community energy system (CES) with DGs is a new participant in the energy market. DG's purchase price from the market is different from the DG's sales price to the market due to transmission service charges and other costs. Therefore, CES who owns DGs has to control the produced electric power per hourly period in order to maximize profit. Considering the international environment regulations, CE will be an important element to decide the marginal cost of generators as well as the classified fuel unit cost and unit's efficiency. This paper introduces the optimal operation of CES's DG connected to the distribution network considering CE. The purpose of optimization is to maximize the profit of CES. A Particle Swarm Optimization (PSO) will be used to solve this complicated problem. The optimal operation of DG represented in this paper would guide CES and system operators in determining the decision making criteria.

Experiential marketing focuses on the experience of customers to connect a company and a brand with the lifestyle of customers that influences buying behavior. This study investigates how the persons who experienced brand ambassadors for public relations as experiential marketing recognized brand equity, how personal satisfaction accomplished as a brand ambassador influenced brand equity, and how the effects are different based upon demographic information. The research methodology was a questionnaire distributed to individuals who experienced work as a public relations brand ambassador. A total of 104 returned questionnaires were analyzed by internal validity, t-test, and regression analysis with SPSS 12.0. The results of this study are as follows: Experiential marketing through a public relations brand ambassador positively influenced brand equity. The satisfaction at the company while working as brand ambassador positively influenced brand equity. Experiential marketing influenced more men than women regarding perceived quality and brand loyalty among brand equity. There is no significant differences regarding career (bank or apparel) among brand awareness, brand image, perceived quality, and brand loyalty.

Purpose: The aim of this study was to investigate the dietary quality of food consumed away from home among Korean children and adolescents. Methods: Data were obtained from the 2010~2012 KNHANES (Korea National Health and Nutrition Examination Survey) and included 3,583 subjects aged 7 to 18 years old. The frequency of food consumed away from home was dichotomized into more than once or less than once per day. Results: Thirty percent of subjects were shown to consume food away from home more than once per day, and older children from higher income households showed a higher frequency of food consumed away from home compared to other children. The percentage of children and adolescents cited as regularly skipping breakfast was 19%. Individuals who ate out more than once per day showed higher consumption of energy and sodium than those who ate out less than once per day. Conclusion: Excessive intakes of energy and sodium are associated with obesity, high blood pressure, diabetes, and obesity-related diseases. Thus, there is a need for nutritional intervention and educational efforts to improve child nutrition and prevent obesity.

Purpose: We did a retrospective study to understand the prognostic effects of preoperative blood transfusions in stomach cancer surgery. Materials and Methods: Data for 1,360 patients who underwent gastrectomy for stomach cancer between 2001 and 2009 were retrospectively reviewed. We analyzed factors that affect preoperative transfusion and clinicopathologic features. We also analyzed 5-year and overall survival rates of the transfusion and non transfusion subgroups. Results: Sixty patients (4.4%) required blood transfusion within the preoperative period. The transfused group included patients who took aspirin or clopidogrel (P<0.001), with more advanced T stages (P<0.001), with more advanced nodal metastasis (P=0.00), and with more advanced stages (P=0.00) than the non transfusion group. On multivariate analysis, preoperative transfusion was a statistically significant negative influence on 5-year survival and overall survival rates (58.2% vs 79.9% (P=0.00), 58.2% vs 76.8% (P=0.00)). Applying Cox-regression analyses, blood transfusion did appear to have an effect on prognosis and on 5-year and overall survival rates. Conclusions: We found a direct negative relation between preoperative transfusion and long term prognosis in patients receiving gastric cancer surgery.

Objective : To introduce the frequency and segment analysis of in-stent stenosis for intracranial stent assisted endovascular treatment on complex aneurysms. Methods : A retrospective study was performed in 158 patients who had intracranial complex aneurysms and were treated by endovascular stent application with or without coil embolization. Of these, 102 patients were evaluated with catheter based angiography after 6, 12, and 18 months. Aneurysm location, using stent, time to stenosis, stenosis rate and narrowing segment were analyzed. Results : Among follow-up cerebral angiography done in 102 patients, 8 patients (7.8%) were shown an in-stent stenosis. Two patients have unruptured aneurysm and six patients have ruptured one. Number of Neuroform stents were 7 cases (7.5%) and Enterprise stent in 1 case (11.1%). Six patients demonstrated in-stent stenosis at 6 months after stent application and remaining two patients were shown at 12 months, 18 months, respectively. Conclusion : In-stent stenosis can be confronted after intracranial stent deployment. In our study, no patient showed symptomatic stenosis and there were no patients who required to further treatment except continuing antiplatets medication. In-stent stenosis has been known to be very few when they are placed into the non-pathologic parent artery during the complex aneurysm treatment, but the authors found that it was apt to happen on follow up angiography. Although the related symptom was not seen in our cases, the luminal narrowing at the stented area may result the untoward hemodynamic event in the specific condition.

Purpose: This study was done to explore the relationship of social support and meaning of life to suicidal thoughts among patients with cancer. Methods: Data were collected by questionnaires from 138 patients who had been in cancer treatment at medical clinics and 8 patients who were members of an internet cancer association. The data were collected between August and November 2009 and analyzed using SPSS 12.0. Results: Of the participants, 47.3% reported having had suicidal thoughts and 16.4% had attempted suicide since the diagnosis of cancer. The study participants received most support from family members, but 73.3% reported experiencing an existential vacuum. The suicide attempt group had significantly higher scores according to gender, age, level of education, diagnosis, treatment modality, level of activity, caregiver and social support compare to the suicide thought group. Suicidal thoughts were negatively related to social support and meaning of life was positively associated with social support. Support from family and friends and diagnosis explained 50.0% of variance for suicidal thoughts with 36.0% of variance being explained by family support. Conclusion: Nurses should be able to identify risk factors for suicide in cancer patients. Prevention and intervention efforts need to be directed toward improving social support, family support in particular, and assisting patients finding meaning in life after a diagnosis of cancer.

Most public guide robots installed in public spots such as exhibition halls and lobbies of department store etc., have poor capability to distinguish the users who require services. As to provide suitable services, public guide robots should have a human detection system that makes it possible to evaluate intention of customers from their movement direction. In this paper, a DPS (Directional Perception System) is realized based on face detection technology. In particular, to catch human movement efficiently and reduce computational time, human detection technology using face rectangle, which is obtained from the human face, is developed. DPS determines which customer needs services of public guide robots by investigating the size and direction of face rectangle. If DPS is adapted, guide service will be provided with more satisfaction and reliability, and power efficiency also can be added up because public guide robots provide services only for the users who expresses their intentions of wanting services explicitly. Finally, through several experiments, the feasibility of the proposed DPS is verified.

Purpose: This study was done to identify change in self-concept of smoking experience in middle school students. Method: The study was a longitudinal survey design and used only the responses on self-concept and smoking state from the data of the Korea Youth Panel Survey (KYPS). The sample for this study consisted of 3,449 middle school students and the data were collected over a two-year period (2003-2004). Results: Self-esteem scores for the first and second year were significantly higher and self-stigma and aggression scores were significantly lower in the non-smoking maintenance group. There was a significant increase in self-esteem scores for students in second year who quit smoking compared to those in first year. There was a significant decrease in scores for attachment to surrounding people and emotional sense of control in second year students compared to those first year for students in the non-smoking maintenance group and the group that quit smoking. Self-intimacy scores were significantly lower in the smoking maintenance group. There was a significant increase in sex-role identity scores in second year students compared to those in first year for students in the group who newly started smoking. Conclusion: Findings from this study can contribute to designing appropriate smoking prevention strategies to improve self-constructs related smoking experiences in adolescents.
