Purpose: The management of splenic injuries has shifted from a splenectomy to splenic preservation owing to immunity. The purpose of this study was to assess the kinds of management and outcomes through a review of our experience with splenic injuries. Methods: We retrospectively reviewed 47 patients with traumatic splenic injuries using by electronic medical records from Jan. 2007 and Dec. 2011. Splenic injuries were classified according to the American Association for the Surgery of Trauma (AAST) grading system. Results: There were 11 falls, 11 traffic accidents, 10 motorcylcle accidents, 10 pedestrian accidents and 5 abdominal blunt traumas. Low-grade injured patients (${\leq}$ Grade III) were 29 of 43(61.7%), and High-grade injured patients (${\geq}$ Grade IV) were 18 of 43(38.3%). In 34 patients, non-surgical treatment was performed, and 14 patients underwent a splenectomy. There were relatively more high-grade in older patients, and the high-grade-injury group showed need for a transfusion (p=0.002), more need for a splenectomy (p<0.001), a longer mean hospital stay (p=0.036), a longer ICU stay (p=0.045) and more combined organ injury (p=0.036). Conclusion: Conservative treatment should be considered in low-grade-injury patients (${\leq}$ Grade III). A Splenectomy was performed on 56% of the patients with Grade IV injuries, so a splenectomy should be considered carefully in such patients. In patients with a grade V injury, we think surgical treatment may be needed.

Little data exists on metabolic syndrome (MetS) related with intake, especially for the South Korean. The purpose of this study was to develop and evaluate a food frequency questionnaire (FFQ) for nutritional assessment in the population with MetS in South Korea. Randomly selected female participants, mean age 21.9 years (n = 38) were invited to answer the FFQ twice (FFQ1 and FFQ2) over a nine-month interval and to complete twelve-day diet records (DR) during the months between in South Korea. The correlation coefficients for nutrient intake between FFQ1 and FFQ2 varied from 0.253 (niacin) to 0.573 (cholesterol), and the energy intake-adjusted correlation coefficients ranged from 0.187 for protein to 0.662 for iron. The energy intake-adjusted and de-attenuated correlation coefficients for comparison of FFQ1 and the DRs ranged between 0.277 (vitamin $B_1$) and 0.768 (fiber), and between 0.229 (zinc) and 0.859 (fat) for comparison of DRs with FFQ2. The percentages of study subjects classified into the same quartiles in both the DRs and FFQ1 ranged from 15.8% (vitamin $B_6$) to 47.4% (calcium), and for the same quartiles in DRs and FFQ2 from 13.2% (vitamin $B_1$) to 44.7% (potassium). The FFQ has reasonably good validity and reproducibility. Further research is needed for an assessment of reproducibility and validation of present FFQ in the subjects with MetS.

The records of 268 patients, who were diagnosed as spontaneous pneumothorax during the period 1975 to 1984, treated at the department of thoracic and cardiovascular surgery, Hanyang University Hospital, were reviewed retrospectively to evaluate the effect of surgical intervention on each indications. Of these,.61 patients [22.8%] were taken operation to treat the pneumothorax after closed thoracostomy. We have classified the 61 patients to evaluate the therapeutic effect on each indications. And the therapeutic effect is based on the chest tube indwelling days. The results were as follows: 1. The chest tube indwelling days of the group who were taken closed thoracostomy only was average 14.13*9.17 days [range 5-66 days], and that of the group who were finally taken the thoracotomy after closed thoracostomy was 21.85*12.30 days [range 5-55 days]. 2. The indications of thoractomy were thoracoscopic findings, recurrence and continuous air leakage. 3. The chest tube indwelling day of the group who was taken thoracotomy by thoracoscopic findings was average 11.67*6.51 day, that was relatively short compared to those of the other groups. 4. The continuous air leakage group after closed thoracostomy was subdivided into three subgroups, continuous air leakage in 1st attack, thoracoscopic findings in 1st attack, and recurrence. 5. Of these, the chest tube indwelling day of the subgroup, who was taken operation by thoracoscopic findings, was 21.33e8.26, that was relatively short compared with those of the other subgroups. We use the thoracoscope as excellent diagnostic tool to detect the operation indication in the spontaneous pneumothorax patients. And we gain the benefits to shorten the chest tube indwelling days and admission days, and also to protect the recurrence.

Because of the changes made in the modes of cataloguing and classification in its long history, the present catalogue of the National Central Library has become complicated and provides an inadequate guide to its collection. There can be no doubt that this is a serious deficiency in a closed access library since materials housed in the library are virtually inaccessible to unskilled readers. The whole breakdown of the efficiency of the catalogue is emminent and will ultimately create the most serious problems for the library. The main purpose of this survey is: (a) to identify problem areas created by the frequent changes in the cataloguing and classifying principles in the library and (b) to grope a rational direction for the future development. Analysing the various classification schemes and cataloguing rules adopted in processing materials (mainly books) in the library, the following conclusions have been made. A. The library adopted five different clasification schemes in different periods, of which KDCP was used for the most part of its collection. KDCP is recommended to use for the future colletion. A classification development office is recommended to be established within the library, of which the main function is to revise the KDCP in collaboration with the appropriate committee of the Korean Library Association. B. The present practice in the library is to apply three different cataloguing rules and two different author notation tables to the Oriental, classical, and Western collections. Efforts should be made to find out an efficient system so that this variety is simplified. An alphabetical index should be added to the classified catalogue, and improvements are required in the Japanese collection. C. The technical services division is inadequately staffed. The staff should be sufficiently numerous and specially qualified. D. The present financial support for the technical services of the library is inadequate. Sufficient financial provision should be made to ensure the effective work. E. A feasibility study should be carried out to develop a computer processing system for providing machine-readable catalogue records on magnetic tape for use by the library community in Korea.

Purpose: This study was undertaken to review the precise morphological patter'ns of polydactyly of the foot and to evaluate outcomes of surgical interventions. Materials and Methods: The records of patients who had polydactyly of foot from 1983 to 2000 were reviewed retrospectively. 29 duplicated toes(24 patients) were analyzed. All cases were evaluated and classified with Temtamy and McKusick's axial pattern, Watanabe's morphologic pattern and level of duplication. Clinical evaluation was performed according to Phelps and Grogan's. Mean age at surgery was 5.7 years(range: 10 months$\sim21$ years). All the patients were subsequently evaluated during mean 17 months(range: 13 months-$\sim5$ years). Results: Preaxial polydactyly was seen in 3 cases, central polydactyly in 3 cases, postaxial polydactyly in 22 cases and remaining 1 case was multiple my involvement. Only 2 patients have familial history and the most common associated anomaly was hand deformity(20.8%). Clinical results were excellent in 14 cases, good in 5 cases, poor in one. 17 patients(70%) were operated before 6 years olds and they had better results than those of who were operated after 6 years olds. Conclusion: The Method of surgical correction for the polydactyly should be individualized by its morphological pattern because the purpose of operation was to give comfort in wearing shoes and patient's psychological relief. This study showed that polydactyly of the foot could be corrected surgically with good results in most cases, and the better results would be achieved if the operation is performed before preschool age according to its individualized pattern of duplication.

Objective : In patients with spontaneous intracerebral hemorrhage (ICH), the risk factors for seizure and the effect of prophylactic anticonvulsants are not well known. This study aimed to determine the risk factor for seizures and the role for prophylactic anticonvulsants after spontaneous ICH. Methods : Between 2005 and 2010, 263 consecutive patients with spontaneous ICH were retrospectively assessed with a mean follow-up of 19.5 months using medical records, updated clinical information and, when necessary, direct patient contact. The seizures were classified as early (within 1 week of ICH) or late (more than 1 week after ICH). The outcomes were measured with the Glasgow Outcome Scale at discharge and the modified Rankin Scale (mRS) at both 2 weeks and discharge. Results : Twenty-two patients (8.4%; 9 patients with early seizures and 13 patients with late seizures) developed seizures after spontaneous ICH. Out of 263 patients, prophylactic anticonvulsants were administered in 216 patients. The prophylactic anticonvulsants were not associated with a reduced risk of early (p=0.094) or late seizures (p=0.326). Instead, the factors associated with early seizure were cortical involvement (p<0.001) and younger age (60 years or less) (p=0.046). The risk of late seizure was increased by cortical involvement (p<0.001) and communicating hydrocephalus (p=0.004). The prophylactic anticonvulsants were associated with a worse mRS at 2 weeks (p=0.024) and at last follow-up (p=0.034). Conclusion : Cortical involvement may be a factor for provoked seizures. Although the incidence of early seizures tended to decrease in patients prescribed prophylactic anticonvulsants, no statistical difference was found.

Purpose: The lateral orbital wall fractures have been previously classified by some authors. As there are some limitations in applying in their own classifications, we hope to present a refined classification system of the lateral orbital wall fracture and to identify the correlation between the specific type of the fracture and clinical diagnosis. Methods: The facial bone CT scans and medical records of 78 patients with the lateral orbital wall fractures were reviewed in a retrospective manner. The classification is based on the CT scan. In type I, the fracture and its segments are away from the lateral rectus muscle and in type II, they are next to or slightly pushing the muscle in axial CT scan. In type III, the fracture segments compress and displace the longitudinal axis of the muscle or the optic nerve in axial view of CT scan. Type IV fracture includes multiple fractures found around the orbital apex or optic canal in coronal view of CT scans of the type I and type II fractures. Results: The most common fracture pattern was type I(43.6%), followed by type IV(29.5%), type II(20.5%), and type III(6.4%). As diplopia and restriction of extraocular muscles were found in type I and II fractures, severe ophthalmic complications such as superior orbital fissure syndrome, orbital apex syndrome, and traumatic optic neuropathy were found in type III and IV fractures almost exclusively. Conclusion: We propose an easy classification system of the lateral orbital wall fracture which correlates closely with ophthalmic complications and may help to make further treatment plan. In Type III and IV fractures, severe ophthalmic complications may ensue in higher rates, so early diagnosis and treatment should be performed.

This study investigated Balgis (the record of the court)in the Joseon Dynasty pertaining to table settings for Sangsik (the meals for the dead). Sangsik are the records of daily meals for kings and key figures. In this study,14 pieces of Sangsikbalgi from 1890 to 1920, including two pieces from an unspecified period, were investigated to determine the composition and types of daily meals in the court. Meals consisted of a minimum of 10 dishes to a maximum 21 dishes, which basically included rice and soup. 'Jochi' was the term to refer to jjigae (stew) in the court. In Sangsikbalgi Bokgi, Gamjang, Jochi, Jjim, Suk, and Cho were all considered Jochi, which were recorded before Jeok or Jeon, where the side dishes were listed after rice and soup. This corresponded with the record of the royal tables in Wonhaeng-Ulmyo-Jeongri-Uigwe (圓行乙卯整理儀軌), in which Jochi included Jabjangjeon, Bokgi, Jabjang, and Cho. Whitebait and fruit, which are used as ingredients for Tang (soup) and Jeon, showed seasonal characteristics however, no other observed dishes showed seasonal variability. Additionally, beef and internal organs of animals were frequently used,regardless of seasons. When dishes in Sangsik were classified into basic dishes and additional cheop dishes (side dishes) based on Siuijeonseo (are recipe book of unknown authorship written in the late Joseon Dynasty), from five to nine Cheop dishes were set on the table, with seven being most common. Further comprehensive study needs to be conducted through undisclosed documents and private collections. Moreover, additional study of Judarye (anestral rites during the day for the royal) and cooking methods that were not investigated in detail in this study are needed.

Back ground: Nurses now occupy one third of all hospital human resources. Therefore, efficient management of nursing manpower is getting more important. While it is very clear that nursing workload requirement analysis and patient severity classification should be done first for the efficient allocation of nursing workforce, these processes have been conducted manually with ad hoc rule. Purposes: This study was tried to make a predict model for patient classification according to nursing need. We tried to find the easier and faster method to classify nursing patients that can help efficient management of nursing manpower. Methods: The nursing patient classifications data of the hospitalized cancer patients in one of the biggest cancer center in Korea during 2003.1.1-2003.12.31 were assessed by trained nurses. This study developed a prediction model and analyzing nursing needs by data mining techniques. Patients were classified by three different data mining techniques, (Logistic regression, Decision tree and Neural network) and the results were assessed. Results: The data set was created using 165,073 records of 2,228 patients classification database. Main explaining variables were as follows in 3 different data mining techniques. 1) Logistic regression : age, month and section. 2) Decision tree : section, month, age and tumor. 3) Neural network : section, diagnosis, age, sex, metastasis, hospital days and month. Among these three techniques, neural network showed the best prediction power in ROC curve verification. As the result of the patient classification prediction model developed by neural network based on nurse needs, the prediction accuracy was 84.06%. Conclusion: The patient classification prediction model was developed and tested in this study using real patients data. The result can be employed for more accurate calculation of required nursing staff and effective use of labor force.
