Objectives: To evaluate the occurrence of patient adverse events in Korean hospitals as perceived by nurses and examine the correlation between patient adverse events with the nurse practice environment at nurse and hospital level. Methods: In total, 3096 nurses working in 60 general inpatient hospital units were included. A two-level logistic regression analysis was performed. Results: At the hospital level, patient adverse events included patient falls (60.5%), nosocomial infections (51.7%), pressure sores (42.6%) and medication errors (33.3%). Among the hospital-level explanatory variables associated with the nursing practice environment, 'physician-nurse relationship' correlated with medication errors while 'education for improving quality of care' affected patient falls. Conclusions: The doctor-nurse relationship and access to education that can improve the quality of care at the hospital level may help decrease the occurrence of patient adverse events.

Background: Hospital admissions for ambulatory care sensitive conditions (ACSCs), which are widely used as an indicator of poor access to primary care, can be used as an efficiency indicator of healthcare use in countries providing good access to health care. Korea, which has a national health insurance (NHI) system and a good supply of health care resources, is one such country. To quantify admission rates of ACSC and identify characteristics influencing variation in Korean health care institutions. Methods: By using NHI claims data, we computed the mean ACSC admission rate for all institutions with ACSC admissions. Results: The average ACSC admission rate for 4,461 institutions was 1.45%. Hospitals and clinics with inpatient beds showed larger variations in the ACSC admission rate (0%-87.9% and 0%-99.6%, respectively) and a higher coefficient of variation (7.96 and 2.29) than general/tertiary care hospitals (0%-19.1%, 0.85). The regression analysis results indicate that the ACSC admission rate was significantly higher for hospitals than for clinics (${\beta}=0.986$, p<0.05), and for private corporate institutions than public institutions (${\beta}=0.271$, p<0.05). Conclusion: Substantial variations in ACSC admission rates could suggest the potential problem of inefficient use of healthcare resources. Since hospitals and private corporate institutions tend to increase ACSC admission rates, future health policy should focus on these types of institutions.

Purpose: The living standards vary between the urban and rural areas in Korea. This study aims to compare the characteristics of acute poisoning victims in urban and rural areas. Methods: A retrospective study was conducted over a period of 2 years from 2008 to 2009. The study group included adults over 19 year old with acute poisoning and who were later were admitted to the local emergency medical center located in Daegu, Korea. The exclusion criteria were 1) the victims of adverse effects of therapeutic doses of drugs, 2) the victims with chronic exposure and 3) the victims who were missing data in their emergency medical records. We divided the victims into the adult group (19-64 years old) and the old group (over 65 years old). Results: There were 569 acute poisoning victims during the study period, and they constituted 1.11% of the total ED visits (51,199). Four hundred seventy six patients were enrolled in this study. Out of the 359 acute poisoning victims, 252 victims were from urban areas and 107 victims were from rural areas. They showed statistical differences for gender, ED access, transport, toxins and the time to the ED. In the old group, 61 victims out of 117 were from urban areas and the remaining 56 victims were from rural areas. They showed statistical differences for gender, ED access, toxins and transport. Conclusion: Through the clinical comparison between the acute poisoning victims of urban and rural areas, we exposed the clinical differences between the urban and rural areas, and we concluded that prevention and education for acute poisoning should be generated differently between the two groups.

Four monkeys (Macaca mulatta) were allowed to press a lever in their cages in order to earn access to one gram pieces of Panax ginseng root. Self-administration performance on an operant schedule (mult FR20 F11) was characterized by frequent pauses and increased intertrial interval responding. When given 23 hour unlimited access to ginseng root, as well as to food and water, all animals titrated their daily intake to approximately 1.5 g/kg. Gross behavioral changes included increases in vocalization, activity, stereotyped movements, and weight loss. These patterns of behavior are typical of those seen when monkeys self-administer psychomotor stimulants. Further studies on ginseng's reward value can be conducted using this animal model.

Although abundant biology data have been accumulated in public biology databases, such as GenBank and PIR, few easy-interface services are provided for users to access or update them. We have developed a system, named BioStore, that is composed of several programs to aid users to not only access public data but also share their own data easily. The service can be used for maintaining a local database as a repository of raw data files of several public databases and distributing the data files to other users. Currently, BioStore manipulates major bio-databases and will expand to include more databases and more useful interfaces.

Intraoperative airway obstruction is perplexing to anesthesiologists because the patient may fall into danger rapidly. A 74-year-old woman underwent an emergency incision and drainage for a deep neck infection of dental origin. She was orally intubated with a 6. 0 mm internal diameter reinforced endotracheal tube by video laryngoscope using volatile induction and maintenance anesthesia (VIMA) with sevoflurane, fentanyl ($100{\mu}g$), and succinylcholine (75 mg). During surgery, peak inspiratory pressure increased from 22 to $38cmH_2O$ and plateau pressure increased from 20 to $28cmH_2O$. We maintained anesthesia because we were unable to access the airway, which was covered with surgical drapes, and tidal volume was delivered. At the end of surgery, we found a longitudinal fold inside the tube with a fiberoptic bronchoscope. The patient was reintubated with another tube and ventilation immediately improved. We recognized that the tube was obstructed due to dissection of the inner layer.

Objectives: Pulse is a method of Korean medicine diagnosis and is an important clue to detect the organs, nature, and progress of the disease. Pulse examination is included in the basic examination of Korean medicine doctors, but there is no standardized method for diagnosing pulse although the types and methods of the pulse taking are briefly described in the literature, making it difficult to spread the examination method. In this regard, I would like to propose an objective evaluation method. Methods: Although the importance of pulse examination and the method of pulse examination are known in the literature, it is difficult for undergraduate students or inexperienced Korean medicine doctors to access it, so in this paper a method of marking the size of the pulse power in the blank space for objective evaluation was devised and presented. Results: The size of the pulse power should be indicated using the 1-cell, 3-cell, or 5-cell method according to the left and right wrists and the cun, guan and chi on both sides. Conclusion: The method of pulse diagnosis is an important diagnostic method as a verification process for making a Korean medical diagnosis. The remaining Korean medicine diagnostic methods, including pulse diagnosis, also need to undergo objectification. It is believed that the objectification of these diagnostic methods will lead to an improvement in the treatment rate of Korean medicine.

Purpose: Coronally advanced split-or full-thickness (CAST or CAFT) flaps in combination with subepithelial connective tissue grafts (SCTGs) are commonly used in root-coverage procedures despite postoperative pain and bleeding from the graft donor site. Therefore, the modified vestibular incision subperiosteal tunnel access procedure (VISTAX) uses a novel collagen matrix (VCMX) instead of autogenous tissue to address the limitations associated with autogenous tissue grafting. This retrospective study compared the clinical outcomes of VISTAX to the results obtained after using a CAST or CAFT flap in combination with SCTG for root coverage. Methods: Patients with single or multiple adjacent recession I/II defects were included, with 10 subjects each in the VISTAX, CAFT, and CAST groups. Defect coverage, keratinized tissue width, esthetic scores, and patients' perceived pain and dentinal hypersensitivity (visual analogue scale [VAS]) were assessed at baseline, 3 months, and 6 months. Results: All surgical techniques significantly reduced gingival recession (P<0.0001). Defect coverage, esthetic appearance, and the reduction in dentinal hypersensitivity were comparable. However, the VAS scores for pain were significantly lower in the VISTAX group than in the CAFT and CAST groups, which had similar scores (P<0.05). Furthermore, the clinical results of VISTAX and CAFT/CAST generally remained stable at 6 months. Conclusions: The clinical outcomes of VISTAX, CAFT, and CAST were comparable. However, patients perceived significantly less pain after VISTAX, indicating a potentially higher patient acceptance of the procedure. A prospective trial with a longer follow-up period and a larger sample size should therefore evaluate VISTAX further.

Background: Chronic obstructive pulmonary disease (COPD) is a major cause of death and disability worldwide and one of the most prevalent diseases in Korea. We examined trends and risk factors of health care utilization for COPD in Korea. Methods: We retrospectively analyzed the database of Patient Surveys from 1990 through 2008, which were nationwide surveys of health services utilization through outpatient department (OPD) visits and hospitalization. Physician-diagnosed COPD patients whose ages were 45 years and older were included. Results: OPD visits and hospitalization of COPD patients between 1990 and 2008 were estimated to be 68,552 and 17,774 persons, respectively. Trends in OPD visits and hospitalization for COPD significantly increased from 1990 through 2008 (p=0.019, p=0.001, respectively). The increment rate for OPD visits was 2.0 fold over those years; for hospitalization it was 3.3 fold. Risk factors for OPD visits for COPD were male gender (odd ration [OR], 1.41; 95% confidence interval [CI], 1.39~1.43), those aged 65 years and older (OR, 1.50; 95% CI, 1.47~1.53), residential area other than a metropolis (OR, 1.08; 95% CI, 1.07~1.010) and access to a physician's office (OR, 1.17; 95% CI, 1.14~1.21). Risk factors for hospitalization were male gender (OR, 2.15; 95% CI, 2.07~2.23), those aged 65 year and older (OR, 2.86; 95% CI, 2.72~3.00), residential area other than a metropolis (OR, 1.98; 95% CI, 1.90~2.07) and access to a hospital (OR, 2.88; 95% CI, 2.59~3.22) (p<0.001, both). Conclusion: Health care utilization for COPD subjects increased from 1990 to 2008. Risk factors for the utilization were male gender, older age, and residential area other than a metropolis.
