Objective : We studied only patients at the acute stage but existing studies on stroke didn't almost classify the stage. We examined 243 patients admitted to the Woo Suk university oriental medical hospital from January 1998 to December 1999 for 2 years. Methods : We analyzed patients into sex, Sasang constitution, the incidence and lesion according to the stroke types, post and family history, onset time, period to admission and physical treatment from onset, and symptom, blood pressure, cholesterol level and herb medicine at entry. Results : Our study was similar to existing studies in the distribution of sex, age and the lesion of stroke, post and family history, and symptoms at entry. But it differed in the constitution, incidence of cerebral infarction and intracranial hemorrhage, attack time, period to admission and physical treatment from onset day, and the symptoms, blood pressure, cholesterol level and herb medication. In comparison between infarction and hemorrhage patients, there was some difference in the distribution of onset time, but wasn't in the cholesterol level. Conclusions : Our study on the acute stage of stroke was similar to existing studies in the general characteristics. But it showed some differences in the herb medicine at entry. In particular, there were much differences in the blood pressure at entry and the incidence of infarction and hemorrhage. We hoped that stroke patients would be synthetically studied in western and oriental medicine.

Antibody screening and identification tests before blood transfusion are important because unexpected red antibodies can cause acute or delayed hemolytic transfusion reactions. Although a tube method was used for detecting unexpected antibodies, a column agglutination method has recently been used because of its simple procedure and a high detection of warm antibodies. This study investigated the frequency and distribution of unexpected antibodies in transfusion candidates during the recent 5 years, and transfusion characteristics in the identified cases. From January 2005 to December 2009, 46,923 sera of the cases from E hospital were screened and 98 sera were identified by the DiaMed-ID System. 272 cases (0.58%) showed positive results out of all 46,923 cases that underwent unexpected antibodies screening. Among them, unexpected antibodies were identified in 98 cases. The anti-Rh antibodies included in warm antibodies were the most frequently detected in 47 cases (47.96%). Anti-Lewis and anti-MNSs antibodies were detected in 11 cases (11.22%) and 6 cases (6.12%), respectively. Unidentified antibodies were detected in 6 cases (6.12%). Among the patients with unexpected antibodies, 43 cases (43.88%) had a history of previous transfusion. Anti-E was the most frequently detected antibody (4/14 cases, 30.77%) in the cases who had a previous history of transfusion and showed different screening results from negative to positive, This study may provide the basic data for the frequency and characteristics of red cell antibodies.

The structure analyzed in this paper has particular building style and special structural system. It is a rigid-connected twin-tower skyscraper with asymmetrical distribution of stiffness and masses in two towers. Because of the different stiffness between the north and the south towers, the torsion seismic vibration is significant. In this paper, in order to study the seismic response of the structure under both frequent low-intensity earthquakes as well as rare earthquakes at the levels of intensity 7, the analysis model is built and analyzed with NosaCAD. NosaCAD is an nonlinear structure analysis software based on second-development of AutoCAD with ObjectARX. It has convenient modeling function, high computational efficiency and diversity post-processing functions. The deformations, forces and damages of the structure are investigated based on the analysis. According to the analysis, there is no damage on the structure under frequent earthquakes, and the structure has sufficient capacity and ductility to resist rare earthquakes. Therefore the structure can reach the goal of no damage under frequent earthquakes and no collapse under rare earthquakes. The deformation of the structure is below the limit in Chinese code. The time sequence and distribution of damages on tubes are reasonable, which can dissipate some dynamic energy. At last, according to forces, load-carrying capacity and damage of elements, there are some suggestions on increasing the reinforcement in the core tube at base and in stiffened stories.

The lunar gravity field is an important source to understand the lunar interior structure, dichotomy and magma ocean of the moon, furthermore it can be used to study the origin and evolution history of the moon. In this paper, we firstly investigated the history of lunar exploration were performed for determining the lunar gravity field, in addition to investigating the procedure of progress related with the lunar gravity field model and gravity observations techniques. After, we determined practically the gravity anomalies of the moon using the new lunar gravity model, SGM90d (SELENE Gravity Model), which were developed by processing the tracking data from SELENE, the japanese lunar mission. Finally, we compared the lunar gravity anomalies from SGM90d model to the those from existing lunar gravity model (LP165P). As results from the comparison, we can make a sense that 4-way Doppler observations of SELENE is very effective to measure the gravity field on the farside of the moon. The precise lunar gravity field model including the farside of the moon which can be more helpful to understand the dichotomy of moon and to establish the detailed distribution of lunar gravity field, such as a mascon.

Objective : The purpose of this study is to report the effectiveness of a Korean Medicine Treatment on 45 facial atopic dermatitis patients. Methods : Total 45 facial atopic dermatitis patients, who has visited korean medical clinic in year 2011 were analyzed by Objective SCORAD Index(OSI) and Investigator's Global Assessment(IGA). Subanalysis of OSI and IGA were done according to topical ointment user/non-user, treatment period and change in IGA distribution. Results : 1. Male and female percent was 20%:80%. 17.8% were teens, 55.6% were twenties, 13.3% were thirties, 13.3% were above age forty. 64.4% were on topical ointment treatment of corticosteroid or calcineurin inhibitor, and 35.6% were not at the initial visit. Patients with family history were 44.4% and 62.2% had atopic dermatitis past history. 2. OSI and IGA were significantly lower after 1~3, 3~6, 6~9 month of treatment. Average post-treatment score was lower in longer-treated group. 3. IGA distribution has changed from average 3.42 at the first visit to 1.76 at final visit. 91.1% of total patients reported decrease in IGA at the final visit. 4. OSI and IGA improvement rate were significantly higher in non-topical ointment user than the user. Age, treatment period, initial OSI and IGA score difference were not significantly different. Conclusion : A significant percent of 45 facial atopic dermatitis patients who were treated with Korean Medicine Treatment reported decrease in OSI and IGA. The difference increased with the treatment period. Non-topical ointment users' improvement was significantly higher than topical ointment user.

Purpose: This study aimed to investigate the seasonal changes in vitamin D levels in a healthy pediatric population living in mid-latitude East Asian urban areas. Methods: A pediatric population was selected from single secondary hospital visitors. Clinical data and serum vitamin D levels were collected retrospectively. Statistical analyses were performed based on the month of the blood sampling date, subject age, and vitamin D supplementation history. The data were categorized into three subgroups based on serum vitamin D levels-adequate (≥30 ng/mL), insufficient (20-29 ng/mL), and deficient (<20 ng/mL). Results: Of the 481 patients, 172 had vitamin D supplementation history. More than 70% of the total study population had inadequate vitamin D levels (<30 ng/mL). The non-supplemented group and the supplemented group showed significantly uneven monthly distribution of the adequate, insufficient, and deficient subgroups. Only the non-supplemented group showed significantly different average vitamin D levels in the summer months compared to the winter months. In the non-supplemented group, vitamin D levels were the lowest in March, the highest in August and September. Significant relevance was noted between vitamin D supplementation status and vitamin D serum level in February and March. There was no significant difference between different age groups in terms of the distribution of vitamin D levels. Conclusion: Currently-widespread vitamin D replacement methods seem to have some effect on increasing the overall serum vitamin D levels, specifically during late winter when natural serum vitamin D levels plunge. However, they are unable to fully compensate the seasonal fluctuation.

Since the beginning of the second Sino-Japanese war in 1937, the entire Korean Peninsula has entered a full-fledged wartime system. Japan enacted laws that strongly regulate the distribution of various resources for war, and the same was implemented in Joseon. In particular, as iron, copper, lead, tin, and aluminum were mobilized as raw materials for military supplies such as weapons, private distribution decreased significantly, which had a great impact on the construction industry. As the use of metal such as steel as building materials requires permission from the provincial governor, it has become difficult to supply and demand except for some military facilities. In addition, the Japanese Ministry of Commerce and Industry encouraged research and development and manufacturing to promote the so-called "substitute goods industry" to make up for the shortage of supplies. Products with improved performance through chemical treatment by injecting only a small amount of the same raw material than before or using alternative raw materials have been developed. It was intended to overcome the limitations of lack of raw materials through the chemical industry. In terms of building materials, various substitutes were produced due to the incorporation of petrochemicals and the use of synthetic resins. This trend continued even after the end of the war and served as one of the backgrounds for R&D and production of new materials without returning to the "substitute goods."

A procedure for determining the lateral load pattern for pushover analysis which includes higher mode effects is presented in this study. It is well-known that the details of future earthquakes at particular site is almost impossible to predict accurately and that the code-design spectra try to represent at least the average nature of probable future earthquakes. Thus the code-design spectrum is directly used as the input earthquakes in this paper when incorporating higher mode effects in the pushover analysis so that the efforts for selecting input motions and constructing response spectrum needed in some existing method could be avoided. A case study based on the time history analysis of a irregular steel moment frame showed that the procedure proposed in this study generally outperforms various pushover analysis procedures of ATC-40 and FEMA 273. However, the proposed procedure tended to be conservative as compared with the time history analysis method.
