Objectives: Guardians of patients have a great deal of influence on decision-making in the course of care in Korea. The purpose of this study was to explore the effect of nursing service satisfaction on hospital re-use intention in the guardians of patients admitted to comprehensive nursing care units. Methods: The survey was conducted on 151 guardians of patients hospitalized in comprehensive nursing care units of two general hospitals for four months beginning in September 2017. The data were analyzed with descriptive statistics, t-tests, Pearson's correlation coefficient, and multiple regression analyses using SPSS/Win 21 software. Results: Nineteen percent of variance in hospital re-use intention was accounted for by reliability (t=3.31, p=.001), empathy (t=2.49, p=.014), and recommendations from others (t=2.49, p=.014). The explanatory power was significant (F=13.06, p<.001). Conclusions: To promote hospital reuse, nurses need to improve the quality of their nursing services. Emphasis should be on reliability and empathy among nursing service components. It is also necessary to consider ways to encourage guardians who used hospitals to recommend them to their acquaintances.

The antibacterial activities of nine oriental herbal medicine extracts were measured against seven kinds of bacteria known to cause food poisoning and disease. The extracts were prepared with distilled water using an autoclave ($121^{\circ}C$ for 30 min). The extraction yields of nine oriental herbal medicines were in the rage of 0.5%-33.4%. The antibacterial activities were evaluated using the paper-disc method. Extracts of Hwangryeon, Jiyu, and Ohbaeja showed antibacterial activities while the others did not. Extracts of Coptis japonica, Hwangryeon, and Sanguisorba officinalis, Jiyu showed antibacterial activities only against Clostridium perfringens and Listeria monocytogenes. Extracts of Rhus javanica, Ohbaeja showed the strongest antibacterial activities against all the bacteria tested. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of R. javanica extracts were in the range of 2.4~20 mg/ml for the bacteria tested. In conclusion, the extract of R. javanica showed superior antibacterial activities against the seven bacterial strains tested. The MIC and MBC values for each bacterium were represented as strain names (MIC, MBC), which were Bacillus cereus (11.2, 20), Clostridium perfringens (2.4, 4.7), Escherichia coli (9.1, 9.1), Listeria monocytogenes (11.1, 20), Salmonella typhi (4.7, 9.1), Staphylococcus aureus (2.4, 4.7), and Vibrio parahaemolyticus (2.4, 5.3). Further purification and study of this antibacterial material would be helpful for developing antibiotics or promoting synergistic effects with known antibiotics, producing antibacterial material for lengthening the shelf-life of food, and so on.

To evaluate the 3-dimensional features of the grafted bone with maxillary sinus augmentation and to assess the relation between the degree of bone resorption and the type of bone grafting source and implant, and the operation method. A retrospective chart review of patients receiving sinus augmentation procedures for implant positioning was conducted: radiographic analysis of the volume and area of bone grafts was performed. The volumetric remodeling.measured at 6 months after implant positioning as the percentage of residual bone graft.was correlated to type of graft materials and operation methods. 53 dental implants positioned with sinus bone graft in 15 patients at Wonkwang University Sanbon Dental Hospital. Computed tomography scans,taken implant positioning after 6 months, showed greater resorption values for the group of $Puros^{(R)}$ graft alone from the group of mixed with $Puros^{(R)}$ and various bone graft (P<0.05, respectively). And resorption values according to operation methods have statistically significant difference(P<0.05). Volume change ratio of bone graft showed greater values for the group of delayed implant position from the group of simultaneously implant placement with bone graft. Retrospective data analysis shows that the method of graft with $Puros^{(R)}$ alone may occur greater resorption of graft materials than mixed graft material with $Puros^{(R)}$ and other graft materials. The group of simultaneously implant placement with bone graft also display smaller resorption ratio of bone graft than the group of delayed implant placement.

Transformation system of rolC gene, dwarf gene in Lycium chinenese Mill. established by using system. Pin-punctured leaves induced numerous adventious buds in abaxial side when cultured on 3/2 MS medium containing 2.0 mg/L zeatin. Survival rate and shoot regeneration frequency of leaf explants decreased as kanamycin sulfate level increased. Shoot buds were not regenerated on 3/2 MS medium containing 10 mg/L kanamycin sulfate and 2.0 mg/L zeaein. Of the level tested, 10 mg/L of kanamycin sulfate was optimum in selection of kanamycin sulfate resistant plant. Co-culture time of bacteria and leaf explants was affected at the frequency of shoot regeneration and survival of leaf explants. Leaf explants co-cultivated during above 48hr severely decreased survival rate and shooting rate. Best result on survival rate and shooting rate were obtained when exposed for 24 h. 80 explants of 105 leaf explants survived on 3/2 MS medium containing 2.0 mg/L zeatin and 10 mg/L kanamycin sulfate, and 15 shoots was regenerated on the same medium. To select kanamycin sulfate resistant plant, regenerate as cultured on 3/2 MS medium containing 10 mg/L kanamycin sulfate, and obtained 5 kanamycin resistant plants. Southern blot analysis conformed that the rolC gene was incorporated into the genomic DNA of kanamycin resistant plants.

Purpose : Active perioperative intervention and improvement on surgical technique has decreased the mortality rate of total anomalous pulmonary venous connection (TAPVC); however, when complicated with pulmonary venous obstruction, operative mortality is still high. The purpose of this study was to investigate the clinical course of TAPVC. Methods : Twenty-seven patients who were diagnosed with TAPVC (without other complex heart anomalies) by echocardiogram at Kyungpook National University Hospital from January 1994 to February 2008 were included. Results : Mean age at diagnosis was $28.1{\pm}33.4$ days (1-126 days). Sites of drainage were supracardiac type (15), cardiac (6), infracardiac (5), and mixed (1). Seven patients had pulmonary venous obstruction: 5 with supracardiac type, 1 with cardiac, and 1 with infracardiac. Intraoperative trans-esophageal echocardiograms were performed in 14 patients (58.3%). The operative mortality was 16.7% (4 of 24) and overall hospital mortality (including deaths without operation) was 22.2% (6 of 27). There were 5 postoperative pulmonary venous obstructions. The sites of obstruction were anastomotic in 3 of 5 (60%) patients, and ostial pulmonary vein in the other 2 (40%) patients. Three patients who presented with anastomotic pulmonary venous obstruction underwent reoperation, but all the patients were found to have pulmonary venous anastomotic obstruction. The other 2 patients with ostial pulmonary vein obstruction who had no significant symptoms were diagnosed by routine echocardiographic examination during follow-up. Conclusion : In TAPVC patients, early diagnosis and aggressive surgical management will improve prognosis, and we must pay attention to early and late pulmonary vein restenosis through intraoperative trans-esophageal echocardiogram and peri- and post-operative echocardiographic follow-up examinations.

The epidemiological researches on the inpatients hospitalized at the oral medicine ward have been continuously carried out since 1970, and most researches have been performed by centering around the oral medicine wards of college hospitals. Numerous specialists have been produced after the establishment of oral medicine, and they have been active in various fields. As dental clinics have gotten bigger, the function of oral medicine in the secondary clinics is being brought out. As admissive channel, case features, case composition and otherwise have not been researched for a long time, the related researches should be carried out from now on. Hereupon, this study was carried out by targeting the 100 inpatients hospitalized at the oral medicine ward of Sun Hospital located in Daejeon Korea, through questionnaire. As the result, the following results were derived. 1. The ages of the inpatients in Sun Hospital were $29.21{\pm}11.31$ on the average; 71 females' mean average was $29.63{\pm}11.29$ and 29 males' mean average was $28.17{\pm}11.48$. In regard of school career, the patients who finished high-school course or higher accounted for 78%; the patients' school career seemed to be relatively high. The patients who complained of temporomandibular pain accounted for the highest proportion with 65%. In motivation to visit this hospital, internet surfing was 11%, mass media was 10%, acquaintance's introduction was 38%. The patients, who were hospitalized at another hospital due to the same symptom, accounted for 56%. The dental clinics, which made the patients visit this hospital, accounted for 20%. The patients, who were previously aware that the present symptom should be treated by oral medicine, accounted for 38%. The patients, who were not aware of the fact in advance, were 62%. The respondents of 51% answered that they were aware of the fact one month or below before hospitalization. 2. The patients, who complained of craniocervical ache, accounted for 58%; the patients, whose ache aches affect dailylife, were 22%. Continuous ache was 14% and intermittent ache was 68%, and dull pain was 23%. 3. Life variations were compared with each other by using SRRS (Social Readjustment Rating Scale). In consequence, the variation within 3 years indicated a significant difference in the both groups but the variation within 6 months did not indicate any differences. 4. In regard of the questionnaire on the incidents happened for a week, the ache-group was compared with the group free from the ache. As the result, the number of strain arisen for a week, the decrease of favorite works and sudden fear indicated a significant difference. Pleasant feeling and the decrease of interests in looks did not indicate a significant difference, but came close to the significance. 5. In the questionnaire on impatience, the ache-group indicated higher value but there was not a significant difference. 6. In the questionnaire on the symptoms caused by stress, the two groups indicated significant differences in the item of 'the teethridge itches and feels a tooth rising' and 'the occiput or the nape is stiff.' In the item 'the inside of the cheek or the teethridge are widely peeled off, accompanied with ache and hemorrhage', 'the face has acne or pimple' and 'headache frequently attacks', a significant difference was not observed but the two groups came close to the significance.

Background: Facial hyperhidrosis patients have as much difficulty in personal relationships as the palmar and axillary hyperhidrosis patients. There have been no appropriate treatment, but recently, satisfactory results have been obtained through sympathetic blockade. Thoracoscopic thoracic sympathectomy for facial hyperhidrosis has been known to resect cervicothoracic (stellate) ganglion, but its inherent complications such as Horner syndrome have made the surgeons hesitant to use this method. We, through our experiences in treating palmar and axillary hyperhidrosis for the past 6 years, believed that T2 sympathicotomy would be enough for facial hyperhidrosis and have experimented and obtained satisfactory results. Material and Method: From June 1997 to May 1998, 38 consecutive patients underwent bilateral thoracoscopic T2 sympathicotomy with 2mm instruments at Seoul National University Hospital. Result: All patients were relieved of excessive sweating in their faces immediately after the operation. Postoperatively, 5 patients (13.2%) required insertion of chest tubes because 3 had incomplete reexpansion of the lung, and 2 had hemothorax from severe adhesion. Other complications related to the surgical procedures, such as Horner's syndrome, and brachial plexus injury, were not detected in any cases. The mean hospital stay was mean 1.7$\pm$0.9 days after surgery. Conclusion: T2 sympathetic ganglion is the appropriate resection site for facial hyperhidrosis, and complications such as Horner syndrome can be prevented by not cutting the stellate ganglion. In addition, it is possible to perform the operation by using a 2 mm thoracoscopic instrument, and may obtain much better results.

This purpose of study was to identify variables predicting basic psychological need in hemodialysis patients. The participants were 134 patients from two major general hospitals and two dialysis center located in J city. Data were collected using self-report questionnaires and physiological index. Data analysis was done by using SPSS WIN 18.0 program for one-way ANOVA, independent t-test, Pearson correlation coefficients, and multiple regression. This study showed a negative correlation between basic psychological need and uncertainty(r=--.464, p<.001), depression(r=-.422, p<.001). In addition, relationships and physiological index were Positively correlated. The uncertainty(${\beta}=-.345$), depression(${\beta}=-.279$), physiological index(${\beta}=-.117$) have a 29% explanatory power for the basic psychological need in hemodialysis patients. Physiological index, uncertainty and depression in turn influenced the basic psychological needs of hemodialysis patients. It is necessary to develop nursing strategies and programs to reduce disease uncertainty and depression in order to increase self-deterministic health behavior through autonomy, competence and relationship satisfaction.
