Background: We have previously found that intra-peritoneal lidocaine instillation before pneumoperitoneum attenuates pneumoperitoneum-induced hypertension. Whether this procedure alters patient's hemodynamic status during operation should be determined for clinical application. This study elucidated the possible mechanism of the attenuation of the pneumoperitoneum-induced hypertension by intra-peritoneal lidocaine before pneumoperitoneum. Methods: Thirty-four patients underwent laparoscopic cholecystectomy (LC) were randomly allocated into two groups. After induction of general anesthesia, 200 mL of 0.2% lidocaine (lidocaine group, n=17), or normal saline (control group, n=17) were sub-diaphragmatically instilled 10 minutes before pneumoperitoneum. The changes in systolic blood pressure, heart rate, central venous pressure, stroke volume, cardiac output, and systemic vascular resistance were compared between the groups. The number of analgesics used during post-operative 24 h was compared. Results: Systolic blood pressure was elevated during pneumoperitoneum in both groups (p<0.01), but the degree of elevation was significantly reduced in the lidocaine group than in the control (p<0.01). However, stroke volume and cardiac output were decreased and systemic vascular resistance was increased after induction of pneumoperitoneum (p<0.05) without statistical difference between two groups. The number of analgesics used was significantly reduced in the lidocaine group (p<0.01). Conclusion: These data suggest that intra-peritoneal lidocaine before pneumoperitoneum does not alter patient's hemodynamics, and attenuation of pneumoperitoneum-induced hypertension may be the consequence of reduced intra-abdominal pain rather than the decrease of cardiac output during pneumoperitoneum. Therefore, intra-peritoneal lidocaine instillation before pneumoperitoneum is a useful method to manage an intraoperative pneumoperitoneum-induced hypertension and to control postoperative pain without severe detrimental hemodynamic effects.

The purpose of this study was to suggest the improvement of the Mountainous Landscape Impact Review(MLIR) system for the conservation and eco-friendly use of mountain scenery. In order to understand the status of the MLIR system, a comparative analysis was conducted of the MLIR official guidelines and the 100 MLIR reports submitted to the Korea Forest Service from 2011 to 2013. In addition, an Importance-Performance Analysis(IPA) was conducted to take into account stakeholder opinions and to determine the first priorities to be improved upon in operation and functions of the MLIR system. The results of the IPA in evaluating the MLIR system showed that the components in the MLIR system that should be primarily improved are mountainous landscape resource inventory, objective and quantitative selection of viewpoints, and a checklist for examining the damage expected in mountainous lands. To Revitalize the Mountainous Landscape Impact Review system, the professional knowledge and experience of the stakeholders should be enhanced by education and training in the MLIR system over the short-term, while the effective functioning of the MLIR system should be reinforced by differentiation and connectivity of the MLIR system with similar institutions, and by emphasizing the uniqueness and properties of mountainous landscapes over the long-term.

Purpose: Well vascularized pectoralis major myocutaneous flap (PMMF) had been a commonly used versatile flap in reconstructive oromaxillofacial surgery since the 1970s. However, after the advent of microvascular surgery in the 1980s, the PMMF was used less frequently. But, to date, PMMF has been useful and has some advantages such as covering wide defects, covering vital structures, back-up procedure in cases of free flap failure, and reconstruction for radiotherapy patients. The purpose of this study is to evaluate the role, indication, complications, functional, and aesthetic results of this flap in the era of free flap with a literature and chart review. Methods: A retrospective study was conducted of 16 oral cancer patients undergoing reconstructive surgery with PMMF for reconstruction of defects from 2001 to 2012 at Kyungpook National University Hospital. The male to female ratio was 10:6, with a mean age of 63 years (16~79 years). Basic demographic data, previous treatment history, indications, dimension of the flap, site of reconstruction, postoperative complications, and patients' final status were systemically analyzed from chart review. Results: The pathology of the disease included squamous cell carcinoma in the majority of cases (n=14). The remaining cases were fibrosarcoma and mucoepidermoid carcinoma. Of the 16 PMMF reconstructions, 13 flaps were applied as primary reconstructive procedures, whereas three flaps were; salvage; procedures (vascularized free flap failure). Twelve patients had complications such as wound dehiscence, infection, hematoma, fistula, flap bulkiness, and partial flap necrosis. The higher complication rates showed an association with utilization of the flap in preoperative radiotherapy cases. However, all patients were discharged without failure. Conclusion: In reconstructive oromaxillofacial surgery, the PMMF is still a useful flap for huge defects. In addition, the PMMF can be used as a salvage procedure after vascularized free flap failure and reconstruction for patients with a history of preoperative radiotherapy.

The purpose of this study was to discern the level of satisfaction of postpartum care in hospitals. the level of importance of traditional postpartum care and the need for home health care for postpartum women. The study's design was to obtain data needed to develop a community-based postpartum care program and to improve the quality of nursing for postpartum care recipients. Data for the study was collected from 1 March to 31 June 2000 from 116 postpartum care recipients treated in Chung-Buk, Korea. Data analysis consisted of frequency, percentage, t-test, and ANOVA. using SPSS win program. The results the of analysis were as follows: 1) The level of satisfaction of postpartum care in the hospital (mean 1.31) was very low. The most laudable items of nursing care by category were: moderate satisfaction with 'perineal wound care' (2.04) and 'afterpain observation'(2.09). The overall level of satisfaction of postpartum care in the hospital. however, was very low. 2) Among other items of postpartum care in the hospital, 'postpartum exercise' $(25.9\%)$. 'assessment and support for postpartum depression' $(25.9\%)$, 'operation wound care for women who underwent Caesarean sections' $(24.5\%)$. and 'contraception and family planning' $(20.4\%)$ showed a need for home health care for postpartum care recipients above $20\%$. 3) The level of importance of traditional postpartum care (Sanhujori) was relatively high (mean 2.72). The importance of Sanhujori by category was as followed: 'the fourth principle: protecting the body from harmful strains' was the highest (2.88), 'the third principle: eating well', 'the first principle: invigorating the body by augmenting heat and avoiding cold', 'the second principle: resting without working', 'the fifth principle: keeping clean' and 'the sixth principle: handling with the whole heart' showed 2.85, 2.80, 2.70, 2.51 and 2.46 respectively. 4) The need for home health care with Sanhujori was very low. 5) The relationship between demographic factors and the level of satisfaction with postpartum care in the hospital was as follows: the satisfaction levels were significantly different among' delivery frequency' and 'health status' alteration after delivery'. 6) The relationship between demographic factors and the importance of the Sanhujori category was as follows: There were no significant differences in the level of importance of the first and the forth principle of Sanhujori. The level of importance of the second principle of Sanhujori was significantly different among 'income' and 'family type'. The level of importance of the third principle of Sanhujori was significantly different among 'having a boy'. The level of importance of the fifth principle of Sanhujori was significantly different among 'income' and 'feeding type'. The level of importance of the sixth principle of Sanhujori was significantly different among 'education background' and 'feeding type'. In conclusion. the findings of this study illustrate the nursing needs of postpartum care recipients. It provides a challenge to caregivers in the healthcare industry to develop a continuous postpartum care program and integrative postpartum care system that embodies the oriental and western paradigm for the promotion of women's health.

A notable recent change in Korean social service delivery is adopting voucher system. A significant portion of foreign literature suggests that the structure of service provision is critical to enhance consumer choice in voucher-based social service delivery system. As domestic research on voucher operation system is very limited, little is known about voucher-based social service provision structure and operating system. Given these limitations in the domestic literature, this study aims to examine the status and effectiveness of voucher-based system with specific focuses on the provision structure of early intervention service for children at the risk of ADHD. Data were collected from 194 service providers across the nation. Based on Cave's analytic paradigm on voucher operating system, data analyses were done to examine (1) the influence of adopting voucher system on service provision system and (2) whether consumer choice has been increased or not. The results indicated that (1) adopting voucher have brought into diversification of service providers, but (2) consumer choice is still limited. Based on these results, future directions for voucher-related policy were discussed.

With the rise of the interest in a renewable system, the importance of the Life Cycle Cost Analysis(LCCA), an economic evaluation tool, has been increasing. However, there is an inevitable gap between a real cost and an estimation from LCCA because of the uncertainty of the external environment in real world. As the input variables in an analysis, such as a real discount rate and an energy cost, ares subject to change as time goes by, strategic decision on the current operating system is made depending on the real cost. Current economic evaluation approaches have treated only the fluctuation of input variables without consideration of the flexibility in operation, which has consequently led to the impairment on the reliability of LCCA. Therefore, new approach needs to be proposed to consider both the uncertainty of input variables and operational flexibility. To address this issue, the application of the Real Option to LCCA is presented in this study. Through a case analysis of LCCA of a solar heating system, the limits and current status of LCCA are identified. As a result, quantitative presentation of strategic decisions has been added in the new approach to implement the traditional approach.

Objectives: This study was performed to investigate the nutritional status, health conditions, eating habits and experience and demand for nutrition dietary management of senior citizens. And these data are formed foundation of development of nutrition dietary management education program and contents in welfare facilities for the aged. Methods: We visited 3 public health centers, 3 senior citizens centers, and 4 welfare centers in Seoul, Gyeonggi-do, Chungnam province, and Daejeon area and carried out interview by semi-structured questionnaire for senior citizens older than 65 years who use those facilities. Results: The study included 17%, 30.7% and 52.3% of senior citizens from public health centers, seniorcitizen centers and and welfare centers, respectively. The age range of 43.9% of the population was 65-74 years and and 56.1% were older than 75 years. We observed that 83.2% of subjects took some medicines due to diseases that they have and 58.0% took prescription medicines for hypertension. The thing that they considered the most when selecting food was 'the taste'(p<0.05). Regarding the level of practice to keep the dietary life, they answered more than 'average' for most of items but answered less than 'average' for lot of salt intake, drinking, exercise. For the experience of nutrition dietary life education, only 19.8% answered 'Yes' and the service for nutrition dietary life management showed the highest score in the demand for 'provide nutritious food'. For the size of consulting group for nutrition/dietary life education, the public health center and welfare center preferred a larger group size but the senior citizens center preferred a smaller group. With regard to who will carry out the consulting, the demand for dietitian was the highest and the operation type showed the high demand in the order of consulting, education. The contents that they want to have consultation in nutrition dietary life education were diet therapy for diseases and the ordinary diet therapy for health. Conclusions: This study suggested the management of nutrition dietry life necessitates qualitative measures according to the different types of welfare facilities. For these, it is in need of development of counseling and education program included therapy for disease. Above all, the policy to secure dietitian of welfare facilities for the aged to perform these should be achived.
