Background: Postoperative atrial fibrillation (AF) is a common complication after coronary artery bypass graft (CABG) surgery. Although postoperative AF is regarded as benign, transient and self-limited, it has been associated with increased morbidity, thromboembolic events and an increased duration and cost of hospitalization. Material and Method: From January 1994 to December 2007, 190 patients that had isolated CABG surgery were divided into two groups. Group 1 (n=139) involved those who had postoperative atrial fibrillation, and group 2 (n=51) did not have any such events. We reviewed the medical records retrospectively including the incidence of postoperative AF, patient characteristics, surgery related factors and the outcome of the patients with postoperative AF. Result: The frequency of postoperative AF was 26.8%, the conversion rate to regular sinus rhythm before discharge was 82.4%; 82.4% of the AF developed within the first three postoperative days. Although the postoperative AF group was significantly older and had a prolonged postoperative Intensive care unit (ICU) stay, there was no difference in the aortic crossclamp time or duration of hospitalization. No spontaneous defibrillation at declamping, and longer duration of cardiopulmonary bypass were significantly related to the development of postoperative AF. However, postoperative treatment with a beta blocker was associated with a decreased incidence of postoperative AF. The multivariate analysis showed that age and ICU stay were significantly associated with the development of POAF. Spontaneous defibrillation and postoperative beta blocker treatment were significantly associated with a decreased frequency of POAF. Conclusion: AF after CABG surgery is a common complication associated with increased morbidity and a longer ICU stay. Therefore, various strategies aimed at reducing AF, and its complications, such as postoperative treatment with a beta blocker should be considered.

Objectives : This study aims to examine satisfaction of dental treatment and revisit and intention of recommendation to dental patients and to supply as a basic resource for dental management improvement. Methods : 645 dental patients to dental hospitals in G City were subjects of this study. 27 dental hospitals were randomly chosen per 5 or 6 in 5 Districts. The intention of the survey was explained to 645 patients and it was agreed to have questionnaire survey. Questionnaire survey was carried out for 2 weeks in April 2011. Total 593 were used for the analysis except for insufficient answer sheets. The analysis was executed by using SPSS 18.0 and the results are as follows. Results : 1. The highest figures are as follows: female was 53.29% in sex, 20-29 age group was 44.52%, graduates of university were 38.62%, students were 28.50%, monthly family income with 300-399 million won was 31.70%. As to the treatment, dental caries were highest with 46.21% followed by scaling with 40.81%. As to the number of visit, 39.80% were over 5 times, and as to the opportunity to use, 29.34% answered it because it is close to home. 2. As to satisfaction, male was 4.15, over 60years old was 4.58, self-employed was 4.33, friendship with dentist as opportunity to use was 4.37. And as to revisit intention, over 60 years old was 4.60, over postgraduate in education level was 4.38, self-employed was 4.43, over 5 times visit was 4.32, and fame as opportunity to use was 4.39 which were the highest. As to the intention of recommendation to others, female was 4.24, over 60 years old was 4.65, self-employed was 4.36, friendship with dentist as opportunity was 4.43 which were the highest and showed significant differences (p<0.05). 3. As to patient satisfaction, there were strong relevance between revisit intention and intention of recommendation with 0.769 and 0.744 respectively. And, as to revisit intention, it had significant relation with revisit intention with 0.791. 4. The explanatory power of the regression analysis on the factors affecting revisit intention was 61.20%. The revisit intention was high when the satisfaction of dental hospital was high (${\beta}$=0.767, p<0.001), the number of visit (${\beta}$=0.026, p<0.01), reason for a visit (${\beta}$=0.070, p<0.01), education level (${\beta}$=-0.063, p<0.05) and occupation (${\beta}$=0.078, p<0.05). 5. The explanatory power of the regression analysis on the factors affecting intention of recommendation was 59.9%. The intention was taken patients satisfaction(${\beta}$=0.601, p<0.001), dental hygienist's kindness (${\beta}$=0.218, p<0.001), female (${\beta}$=0.079, p<0.05), reason for a visit(${\beta}$=-0.059, p<0.05), dissatisfaction treat(${\beta}$=0.084, p<0.05), dentist's kindness (${\beta}$=-0.080, p<0.05), age (${\beta}$=0.054, p<0.05). Conclusions : To improve revisit rate of patients, the refurbishing hospital facility, treatment and kindness of dental hygienists and satisfaction of treatment must be improved. And it also needs to accept complaint from female patients in a positive manner, and understand and correct complaints actively from the perspective of patients.

Purpose : Parents' genetic information plays an important role in their children's genetic expression. Human chromosome has 23-paternal chromosomes and 23-maternal chromosomes. Parental chromosomal translocation can induce clinical problems in their children because of imbalance in genetic information. We intent to analyze the cytogenentic and clinical features about children with maternal balanced translocation between chromosome 15 and 18. Methods : We detected by one family's FISH study of chromosome 15. We have evaluated children born to clinically normal parents about peripheral bood analysis, endocrine, metabolic, radiologic study, electroencephalogram and social & intelligence scale. and We analysis their clinical manifestation by hospital records. Results : Patient's father and elder sister are normal clinically and genetically. Her mother's chromosome show balanced translocation, 46, XX, t(15;18)(p11.2;p11.3). One child has 46, XX, der(18) t(15;18)(p11.2;p11.3), mental retardation, growth retardation, speech & social developmental delay, recurrent infection and mild mitochondria dysfunction. Her young brother has 46, XY, der(15) t(15;18) (p11.2;p11.3), mental retardation, aggressive behavior, obesity and speech developmental delay. Conclusion : In this study we observed the children with developmental delay, dysmorphic facial features, mental retardation, growth retardation associated with growth hormone deficiency and aggressive behavior due to unbalanced translocation between chromosome 15 and 18.

This is a study for the construction of nursing care based upon the Korean attitude toward medicine. Factors which were investigated include the source of nursing care, the reason for choosing care, the type of heath care chosen, the accessability of caregivers, and the desired location of death. The population examined in this study consisted of 517 adults distributed in six large cities and 191 adults from five rural communities. Data was analyzed using frequency, percent, Cronbach alpha, $X^2$ - test, t - test, F - test and scheffe post hoc contrast with an SAS program. The results of this study are summarized as follows: 1. Among sources of nursing care used, first rank rated-pharmacy(54.4), private hospital(18.2), general hospital(8.4), folk remedies in house (5.0), chinese hospital(2.8), prayer(2.8) and others(8.4), and the reasons for choosing nursing care rated 'the easiest method' (63.6), 'the best method'(15.7), 'reliable'(10.8) and 'lower cost burden'(4.6) in order of preference. 2. The type of nursing care chosen rated western medicine(6.80), chinese medicine(6.15), folk remedies(5.46), faith remedies(3.51) and divination remedies (1.41). There were significant differences in the effect recognition degree to various kinds of medicine. 3. The difference of the type of nursing care chosen according to general characteristics showed that urban residents were higher than rural community residents(t=2.15, p=0.0320) in western medicine, and urban residents, women, and singles were higher than rural community residents(t=2.04, p=0.0414), men (t= -2.89, p=0.0039), and married(t=2.50, p= 0.0126) on folk remedies. With repect to age and education those 21-30, under 20 and 31-40, graduated from college and graduate school were higher than above 51, above 61 (F = 7.76, p = 0.0001), graduated from elementary school(F=4.39, p=0.0006) on folk remedies. In other categories, rural community residents, women, younger people. Christians were higher than urban residents ( t = -2.73, p=0.0305), men(t= -4.15, p=0.0001), older people (F=2.48, p=0.0307), Catholic, Buddhist, or atheist (F= 70.18, p=0.0001) on faith remedies. Those graduated from high school and Buddhist were higher than unschooled, graduated from middle school(F=3.18, p= 0.0075), atheist, Catholic or Christian(F=18.32, p=0.0001) on divination redemies. There were significant differences concerning age and education level. 4. The accessibility of caregivers rated 'caregivers should be nearby if the patients need them' (50.0), 'caregivers must be there all day (24 hours)' (39.6), 'caregivers must be there at night only'(5.0), 'caregivers must be there during the day only'(2.6), 'caregivers always should visit during visiting hours' 0.4), 'caregivers don't need to be there at all' (1.2). The frist rank of suitable caregivers were rated as spouse(66.6), mother(24.2), daughter (3.6), daughter-in-law(1.9), and the reasons of thinking thus were rated as 'the most comfortable' (81.5), 'people should correctly with regards to family they'(7.1), 'the easiest' (5.4), 'take good care of the patient' (5.1) and 'lower cost burden' (0.4). 5. The desired location of death rated as the following: his/her house (91. 6) to the hospital(8. 4). A person going to encounter death in the hospital wanted his house(78.5) over the hospital(21.5), and a person dieing in the hospital prefered his house(52.9) over the hospital(47.1) as a funeral ceremony place. The following suggestions are made based on the above results. 1. A sampling method that enhances the re presentativeness should be used in regional and/or national related research and replicated to confirm the result of this study. 2. This study should be used to understand the Korean view of medical centers and to meet the expectations of patients in Korean nursing. 3. Research on the Korean traditional view of humans and expectations of the sick, health and illness, and health behavior, the perception of dying, the decision to heal, and the view of general medicine should continue to be conducted continuosly so that Korean nursing theory can be advanced on these concepts.

Purpose: Various minimally invasive surgical techniques, such as an endoscopic mucosal resection and a laparoscopic gastrectomy, are becoming common practice for some cases of early gastric cancer (EGC) defined in terms of the depth of invasion being limited to the mucosa or submucosa. However, there are rare cases of early gastric cancer with massive lymph-node metastasis. Materials and Methods: From 6 university hospitals of Korea, 2,772 EGC cases were resected during the various period of analysis (1,432 cases of mucosal cancer and 1,340 of submucosal cancer). Results: As control data, we used the data from a single institute, CHA University Hospital. There were nine cases of early gastric cancer (9/2,772, 0.32%) with N3 lymph node metastasis defined by more than 15 lymph nodes being metastasized according to the UICC-TNM classification (pT1N3, stage IV). Two cases were mucosal cancer (2/1,432, 0.1 4%), and seven cases were submucosal cancer (7/1,340, 0.52%). Metastasized lymph nodes varied in number from 18 to 52. There were three male and six female patients with a mean age of 57. This is a totally reversed sex ratio compared to the usual gastric cancer or EGC. Among the total of 9 EGC patients, there were 5 who had superficial spreading carcinomas with surface areas larger than $25\;cm^2$. This is a significantly higher proportion compared to the general EGC population. When we compared the tumor size according to the LN status, the N3 group was definitely larger than the other groups. 78% of the pT1N3 cases showed lymphatic invasion, which is very high compared to the 4.7% in general EGC cases. Among the 9 cases, 6 patients had too short a follow-up period to evaluate the correct prognosis, but there was one patient with a non-curative resection and two patients with early recurrence. Although the sample size is small and the follow-up period is short, we can expect a very poor prognosis when we consider the common prognosis of EGC that is widely known and accepted. Conclusion: From these results, we can a conclude that the risk factors for pT1N3 gastric cancer are female patients, submucosal invasion, larger tumor size, and lymphatic invasion. However rare, the existence of pT1N3 gastric cancer needs to be taken into consideration, especially during the diagnosis. Furthermore, minimally invasive treatment for EGC needs to be chosen with great precaution. Since the prognosis of pT1N3 gastric cancer is expected to be poor, aggressive adjuvant chemotherapy may be necessary. (J Korean Gastric Cancer Assoc 2006;6:109-113)

Background: Long-term low flow oxygen therapy not only increases survival, but also improves the quality of life in patients with chronic obstructive pulmonary disease (COPD) with chronic hypoxemia. For the assessment and improvement of the status of home oxygen therapy, we analyzed clinical experience of 26 patients who have been administered low flow oxygen at home. Method: Twenty-six patients (18 men and 8 women) who have been received long-term oxygen therapy (LTOT) at home were examined. We reviewed physical characteristics, clinical history, pulmonary function test, ECG, arterial blood gas analysis, hemoglobin and hematocrit, types of oxygen devices, inhalation time per day, concentration of administered $O_2$, duration of $O_2$ therapy, and problems in the home oxygen therapy. Results: The underlying diseases of patients were COPD 14 cases, far advanced old pulmonary tuberculosis 9 cases, bronchiectasis 2 cases, and idiopathic pulmonary fibrosis 1 case. The reasons for LTOT at home were noted for cor pulmonale 21 cases, for dyspnea on exertion and severe ventilatory impairment 4 cases, and for oxygen desaturation during sleep 1 case. The mean values of aterial blood gas analysis before home oxygen therapy were $PaO_2$ 57.7 mmHg, $PaCO_2$ 48.2 mmHg, and $SaO_2$ 87.7%. And the mean values of each parameters in the pulmonary function test were VC 2.05 L, $FEV_1$ 0.92 L, and $FEV_1$/FVC% 51.9%. Nineteen patients have used oxygen tanks as oxygen devices, 1 patient oxygen concentrator, 2 patients oxygen tank and liquid oxygen, and other 4 patients oxygen tank together with portable oxygen. The duration of oxygen therapy was below 1 year in 3 cases, 1~2 years in 15 cases, 3~5 years in 6 cases, 9 years in 1 case, and 10 years in 1 case. All patients have inhalated oxygen with flow rate less than 2.5 L/min. And only 10 patients have inhalated oxygen more than 15 hours per day, but most of them short time per day. Conclusion: For the effective oxygen administration, it is necessary that education for long-term low flow oxygen therapy to patients, their family and neighbor should be done, and also the institutional backup for getting convenient oxygen devices is required.

Background : Dysregulation of apoptosis plays an important role in carcinogenesis, tumor progression, and resistance to chemotherapy. X-linked inhibitor of apoptosis (XIAP) is considered to be the most potent caspase inhibitor of all known IAP (inhibitor of apoptosis) family members. This study was designed to assess the pattern of expression and the prognostic value of XIAP in radically resected non-small cell lung carcinoma (NSCLC) patients. Method : The expression of XIAP and its relationship with clinicopathologic parameters (patient age, TNM stage, TNM-pT, TNM-pN, histologic type, VEGF expression, microvessel density, PCNA index) and overall survival were analysed with formalin-fixed, paraffin-embedded blocks from eighty cases of NSCLC. In addition, the apoptotic index (AI) was also assessed. Results : In a regard to histologic type, squamous cell carcinoma (SCC) showed XIAP expression in 91.3%(42/46) and adenocarcinoma (AC) in 61.8%(21/34). The difference was significant(p=0.001). There was no correlation between XIAP expression and other parameters. In the group of AC, XIAP expression showed the signifcant correlation with older age group ${\geq}58years$ and VEGF expression(p=0.028, p=0.014, respectively). The AI in the group with or without XIAP expression were $2.5{\pm}4.9%$ and $18.5{\pm}28.9%$, respectively(p=0.001). Both groups just aforementioned showed no significant difference in median survival time (42.5 months, 29.8 months, respectively). Conclusion : This study suggests that the XIAP expression in NSCLCs could have relation to inhibition of apoptosis, and show differential expression according to histologic type. However, its prognostic role during the progression of NSCLC needs to be further defined.

Glycogen storage disease type IX (GSD IX) is caused by deficiency of phosphorylase kinase which plays a role in breakdown of glycogen. Mutations in PHKA2 are the most common cause of GSD IX (GSD IXa). Clinical manifestations of GSD IXa include hepatomegaly, elevation of liver enzyme, growth retardation, fasting hypoglycemia, and fasting ketosis. However, the symptoms overlap with those of other types of GSDs. Here, we report Korean familial cases with GSD IXa whose diagnosis was confirmed by targeted exome sequencing. A 4-year old male patient was presented with hepatomegaly and persistently elevated liver enzyme. Liver biopsy revealed swollen hepatocyte filled with glycogen storage, suggesting GSDs. Targeted exome sequencing was performed for the differential molecular diagnosis of various types of GSDs. A hemizygous mutation in PHKA2 were detected by targeted exome sequencing and confirmed by Sanger sequencing: c.3632C>T (p.Thr121Met), which was previously reported. The familial genetic analysis revealed that his mother was heterozygous carrier of c.3632C>T mutation and his 28-month old brother had hemizygous mutation. His brother also had hepatomegaly and elevated liver enzyme. The hypoglycemia was prevented by frequent meals with complex carbohydrate, as well as cornstarch supplements. Their growth and development is in normal range. We suggest that targeted exome sequencing could be a useful diagnostic tool for the genetically heterogeneous and clinically indistinguishable GSDs. A precise molecular diagnosis of GSD can provide appropriate therapy and genetic counseling for the family.

Purpose: We aimed to investigate how serum vitamin D levels are related to survival of terminally ill cancer patients. Methods: From May 2012 through June 2013, a retrospective chart review was performed on 96 hospice patients. Univariate and multivariate logistic regression analyses were conducted to identify factors associated with severe vitamin D deficiency and Coxcy and Coxional hazard analyses were used to evaluate effects on survival. Results: The mean vitamin D level in patients was $8.60{\pm}7.16ng/ml$. Vitamin D was severely deficient (<10 ng/ml) in 75 patients (78.2%), deficient (10~20 ng/ml) in 13 patients (13.5%), relatively insufficient (21~29 ng/ml) in five patients (8.3%) and sufficient ((t ng/ml) in three patients (3.1%). Hyperbilirubinemia (${\geq}1.2g/dl$) was the only factor associated with severe vitamin D deficiency according to the multiple logistic regression analysis (Odds ratio, OR=18.48, P<0.05). Although hyperbilirubinemia showed a strong association with survival (Hazard ratio, HR=2.25, P<0.01), no association was found between severe vitamin D deficiency and survival (HR=1.15, P>0.05) in Cox's proportional hazard analysis. Conclusion: Although serum vitamin D levels were severely low in terminally ill cancer patients, we found no association between severe vitamin D deficiency and patient survival.

Purpose: This study was a part of a drive to develop a community health center-based hospice management model which is concerned with hospice care at a community health care setting and available resources of the local community. Methods: Development of a community health center-based hospice management model involved evaluation of existing hospice-related research, including literature review, and research on hospice facilities at the study site, as well as evaluation of model operation. The latter involved community health center-based hospice test operation, and evaluation of test operation by a research team, including of a nursing professor majoring in hospice care and staffs from a community health center in Busan metropolitan city, regional cancer center, and regional terminal cancer patient medical institute. The study was conducted in the 2008 calendar year. Results: The community health center-based hospice management model provides service linked with local community resources, focusing on the local community health center. Financial and administrative assistance is provided by the regional cancer center, with collaboration from academic health care professionals who guide the operation management. The community health center hospice nurse in consultation with a visiting nurse team registers terminally-ill cancer patients and, after assessment, the hospice team prioritize hospice care during team meeting. Care is delivered by staffs and volunteers. Conclusion: The developed community health center-based hospice operation management model maximally utilizes available community health resources to produce qualitative improvement of regional health and welfare policy through improving the lives of home-based cancer patients and their family who are in medical blind spot.
