Purpose: Male hypertrophic nipples can lead to psychological distress and physical discomfort. The authors present a new technique of male nipple reduction and describe its advantages Methods: The neonipple is designed to reduce diameter and height of nipple while preserving the subdermal plexus. After the central wedge excision, additional four triangular section of nipple skin is excised. One of the remaining two flaps is amputated partially and both flaps were approximated using 4 - 0 PDS and 6 - 0 Nylon sutures. Results: Between December of 2007 and January of 2009, 52 nipple reductions were performed in 30 male patients(mean = 29.5 years). Postoperative recovery was rapid and few complications were encountered. The mean diameter of the hypertrophic nipple was $9.1{\pm}2.5mm$(range, 7 to 15 mm). The mean diameter of the neonipple was $5.0{\pm}0.7mm$(range, 4 to 6 mm), with an average reduction of $3.8{\pm}0.6mm$(range, 2 to 11 mm). At follow-up, the neonipple had a natural appearance, with less projection and an inconspicuous scar. Conclusion: The wedge and triangular skin excision and partial amputation are easy to perform and yields consistent results. This technique decreases both the diameter and height of any size nipple and can be modified to meet patient preferences.

Patients' satisfaction while receiving medical service is affected by whether or not their preferences can be met, including time and physician preference. Due to scarcity of medical resource in China, efficient use of available resources is urgently required. To guarantee the utilization ratio, the scheduling decisions are made after all booking information is received. Two integer models with different objectives are formulated separately, maximizing the degree of satisfaction and revenue. The optimal value of the two models can be considered as the bound of corresponding objectives. However, it is improper to implement any of the extreme policies. Because revenue is a key element to keep the hospital running and satisfaction degree is related to the hospital's reputation, neither the revenue nor the satisfaction can be missed. Therefore, hospitals should make a balance. An integrated model is developed to find out the tradeoff between the two objectives. The whole degree of mismatching that is related to patient satisfaction and other separate mismatching degree are considered. Through a computational study, it is concluded that based on the proposed model hospitals can make their decisions according to service requirement.

The purpose of this study was to improve menu management of welfare institutions for mental-disorders. Special objectives were: to analyze dietitians' special considerations for menu planning in the view of nutrition, recipients' food preferences, and foodservice management; and to interprete menus by food groups and food costs. An open-ended questionnaire was developed and sent to 55 dietitians of welfare institutions for mental-disorders by a fax. Dietitians were asked to write their special considerations for menu planning relating to the nutrition, recipients, and menu management. A total of 46 dietitians responded to the questionnaires. Also, 32 weekly menus were sent to analyze in this study. Results of this study showed that dietitians considered specially energy, proteins, vitamins, minerals, and fats for recipients's health conditions and daily RDA. However, dietitians wanted more information about right menu plan manuals for psychiatric patients. Analysis of weekly menus showed that milk and milk products were th most insufficient serving food group in these institutions. Also, snacks (p<0.05)and milk products (p<0.05) serving was significantly affected by higher food costs. The results implicated that future research on menu development should be necessary for nutritional balanced meal services in welfare institutions.

Purpose: This study aimed to explore frontline nurses' experience of patient-centered care and understand the factors affecting its implementation in hospitals. Methods: Four focus group interviews were conducted with 30 nurses in two university hospitals. The following theoretical framework of patient-centered care was used: 1) Respect for patients' values, preferences, and expressed needs, 2) Care coordination and integration, 3) Information, communication, and education, 4) Physical comfort, 5) Emotional support and alleviation of fear and anxiety, 6) Involvement of family and friends, 7) Care transition and continuity, and 8) System issues. We performed a directed content analysis. Results: The most frequent patient-centered nursing practices of the hospital nurses were "promoting physical comfort" in inpatient settings and "providing information and communicating" in outpatient settings. The factors influencing patient-centered nursing included the health professionals' mindfulness, work overload and staff shortage, and unreasonable social demands and regulations. Conclusion: A more comprehensive patient-centered nursing practice should be implemented by improving "care transition and continuity," "family/caregiver involvement," and "system building." Health professionals' mindfulness is significant, and organizational supports addressing work overload and staff shortage are needed alongside change in social awareness.

Objectives: This study used semiology based on traditional Chinese medicine (TCM) to investigate vital energy (Qi) behavior in women with abdominal myofascial pain syndrome (AMPS). Methods: Fifty women diagnosed with chronic pelvic pain (CPP) secondary to AMPS were evaluated by using a questionnaire based on the theories of "yin-yang," "zang-fu", and "five elements". We assessed the following aspects of the illness: symptomatology; specific location of myofascial trigger points (MTrPs); onset, cause, duration and frequency of symptoms; and patient and family history. The patients tongues, lips, skin colors, and tones of speech were examined. Patients were questioned on various aspects related to breathing, sweating, sleep quality, emotions, and preferences related to color, food, flavors, and weather or seasons. Thirst, gastrointestinal dysfunction, excreta (feces and urine), menstrual cycle, the five senses, and characteristic pain symptoms related to headache, musculoskeletal pain, abdomen, and chest were also investigated. Results: Patients were between 22 and 56 years old, and most were married (78%), possessed a elementary school (66%), and had one or two children (76%). The mean body mass index and body fat were 26.86 kg/cm2 (range: 17.7 - 39.0) and 32.4% (range: 10.7 - 45.7), respectively. A large majority of women (96%) exhibited alterations in the kidney meridian, and 98% had an altered gallbladder meridian. We observed major changes in the kidney and the gallbladder Qi meridians in 76% and 62% of patients, respectively. Five of the twelve meridians analyzed exhibited Qi patterns similar to pelvic innervation Qi and meridians, indicating that the paths of some of these meridians were directly related to innervation of the pelvic floor and abdominal region. Conclusion: The women in this study showed changes in the behavior of the energy meridians, and the paths of some of the meridians were directly related to innervation of the pelvic floor and abdominal region.

Background : In these days, the health care organizations have concerned about customer-centered care in order to empower the competitiveness on the health care markets. The departments working for quality management of the hospitals have used health care quality indicators in terms of medical areas as well as service areas of the hospitals. However, there were insufficient efforts to develop the credible measurement to seek the customers' needs, their expectations and their satisfaction levels related to health care services because various kinds of challenges were in the process of scale development to measure customers' satisfaction in health care. The purpose of this study was to develop the satisfaction scale to health care services in a Korea health care organization and to test its tool with validity and reliability. Method : The concept of this tool was acceptability that one of the components of health care quality defined by Donabedian. Acceptability has the five dimensions of concept: Accessibility; Patient-Practitioner Relations; Amenities; Patient Preferences as to the effects of care; and Patient Preferences as to the costs of care. The Satisfaction Tool to Health Care Services was reviewed by expert panel with five researchers, including hospital managers and a professor related to quality management of the hospitals. As a result, the content validity index was .84 in the outpatient satisfaction tool. The inpatient satisfaction tool had .87 of the content validity index. The Satisfaction Tools to Health Care Services finally consisted of 44 items for outpatients/their families and of 60 items for inpatients/their families. Study subjects of the construct validity test were 479 outpatients/their families and 561 inpatients/their families who visited or admitted at a University hospital from July 1, 1996 through August 10, 1996. The data were examined by Factor Analysis with SPSS. Result : The items of Satisfaction tools for outpatients/their families were categorized by eleven factors with eigenvalue greater than 1.0 accounting for 64.2 percent of the variation in item scores. Also, the items of inpatient tool had eleven factors with eigenvalue greater than 1.0 accounting for 60.3 percent of the variation in item scores. The reliability of overall scale were .95 and .96 for the outpatients/their families satisfaction scores and inpatient/their families satisfaction scores. The internal consistency reliability with eleven factors was ranged from .30 to .94 for inpatients/their families. The Satisfaction Tool with eleven factors for inpatients/their families had internal consistency reliability ranged from .53 to .89. Conclusion : The Satisfaction Tools to Health Care Services focused on outpatients/their families and inpatients/their families developed in this study had a high reliability and the strong evidence of content validity and construct validity based on quality concept. Therefore, this tool would be utilized as a credible quality indicator of health care services to assess the quality problems and to monitor the quality improvement activities in Korean Health Care Organizations.
