(1) Authors studied seasonal fluctuation of psychiatric admission preliminarily, based on data of admission to Pusan area for a 4 year period of 1960-1963, and obtained following impressions. (2) The rate of admission in Pusan area and its seasonal fluctuation appear quite similar to those reported by investigators for European, American and Japanese cities. Thus the admission increases in spring and reaches the maximum in May and then gradually decreases toward the end of year. (3) The data obtained by statistical analysis of the seasonal fluctuation in Pusan area were compared with those of foreign ones in order to observe how to be related to the latitude of the locality. It is the general tendency that the lower latitude showed increase of admission in earlier months of the year than the higher latitude did. (4) It is a impression that the admission of affective psychoses are more sensitive to the climatic factors than the schizophrenics. (5) It is conjured by the authors that the socio-cultural and economic factors should be considered to give an account of the seasonal fluctuation of psychiatric admission.

오유환,김형수,김정혁,정규병,서원혁 고려대학교 의과대학 1997 고려대 의대 잡지 Vol.34 No.1
The aim of our study was to evaluate CT features which are helpful in differentiating malignant pleural mesothelioma and metastasis of the pleura. We evaluation CT findings of histopathologically proved 7 cases of mesotherlioma and 15 cases of metastasis retrospectively. The scans were assessed for unilaterality, pleural rind, hilar lymphandenopathy, mediastinal pleura involvement, calcification, pleural effusion, loss of volume, most pronounced lesion area according to trisected hemithorax and prominent nodularity. Unilaterality was seen in 6 cases (86%) of mesothelioma, 13 cases (87%) of metstasis. Pleural rind was seen in 6 cases (86%) of mesothelioma, 9 cases (60%) of metastasis. Hilar lymphadenopathy was seen in 1 case (14%) of mesothelioma, 4 cases (26%). Mediastinal pleural involvement was seen in 6 cases (86%) of mesothelioma, 14 cases (93%) of metastasis. Pleural calcification was seen in 2 cases (29%) in mesothelioma, 2 cases (13%) in metastasis. Pleural effusion was seen in 5 cases (71%) of mesothelioma, 13 cases (87%) of metastasis. Loss of volume was seen 4 cases (57%) of mesothelioma, 10 cases (67%) in metastasis. Mesotheliomas show most pronounced pleural lesion in lower hemithorax in 5 cases (71%), whereas 1 case (7%) in metastasis. Prominent nodularity was more commonly found in metastasis (mesothelioma=29%, metastasis=80%). In the majority of patients, mesothelioma could not be distinguished from metastasis on CT. However, the tendency of mesothelioma to involve the lower hemithorax and the presence of prominent nodularity in metastasis may be helpful CT findings in differentiation of both diseases.

The world’s first geostationary ocean color imager (GOCI) is a three-mirror anastigmat optical system 140 mm in diameter. Designed for 500 m ground sampling distance, this paper deals with on-orbit modulation transfer function (MTF)measurement and analysis for GOCI. First, the knife-edge and point source methods were applied to the 8th band (865 nm) image measured April 5th, 2011. The target details used are the coastlines of the Korean peninsula and of Japan, and an island 400 meters in diameter. The resulting MTFs are 0.35 and 0.34 for the Korean East Coastline and Japanese West Coastline edge targets, respectively, and 0.38 for the island target. The daily and seasonal MTF variations at the Nyquist frequency were also checked, and the result is 0.32 ± 0.04 on average. From these results, we confirm that the GOCI on-orbit MTF performance satisfies the design requirements of 0.32 for 865 nm wavelength.

Receptor Binding Characteristics of Macrophage Inflammatory Protein-1α and -1β
Oh, Kwi-Ok,Jeong, Seung Ryong,Yu, Kang Ryeol,Oh, Hee Jeong,Lee, Dong Whan,Lee, Seong Hee,Kwak, Yak Hoon,Kim, Hyung Seop,Kwon, Byung Se The Official Publication of Korean Academy of Oral 1993 International Journal of Oral Biology Vol.17 No.2
We purified the recombinant murine MIP-1α(rmMIP-1α) and rmMIP-1β, and used the proteins to determine receptor-bearing cells and the binding properties and the relationship between MIP-1α and MIP-1β in the receptor binding properties. Direct receptor binding analysis using radioiodinated rmMIP-1α or -1β indicated a single class of high affinity binding site with a Kd of approximately 0.9-1.5×10^-9M and the presence of approximately 30-4000 binding sites per cell from cytolytic T cell, macrophage, myeloid stem cell, endothelial cell, helper T cell, bone marrow cell, splenocyte, and B cell. Competition binding assays indicated MIP-1α and -1β were able to recognize the common binding site. This is in good agreement with the results from biological function test. Results from cross-linking study and receptor blotting experiment demonstrated that binding molecule might be 30 KDa monomer or 60 KDa homodimer.

흉막삼출액이 있는 폐암환자에서 CT소견과 세포검사와의 비교연구
오유환,이민진,강은영,정규병 고려대학교 의과대학 1997 고려대 의대 잡지 Vol.34 No.1
Pleural effusion is often associated in lung cancer and divided into malignant effusion due to tumor involvement and paramalignant effusion due to a local or systemic effect. When malignant effusion is present the tumor stage is T4 and then, operation is not considered. Therefore, determining whether malignant effusion is or not is important for lung cancer staging and treatment of patients. We retrospectively compared CT findings with cell cytology in 37 patients with pleural effusion associated with lung cancer. Four- teen patients had proven malignant pleural effusion and 23 patients had proven paramalignant effusion by repeated cell cytology of pleural effusion. Comparing CT findings with cell cytology of pleural effusion, the pleural thickening at CT was 38% sensitivity and 64% specificity, and the enhancing pleural nodule at CT was 50% sensitivity and 78% specificity. The positive predictive value of enhancing pleural nodule at CT was 70%. In conclusion, although the result of cell cytology is negative for malignancy in pleural effusion associated with lung cancer, malignant effusion should be considered in the presence of enhancing nodules at CT of the pleura.

Diagnosis of scrub typhus is difficult because of its unspecific symptoms. The authors studied the correlation between serum adenosine deaminase (ADA) levels and scrub typhus, with the aim of aiding diagnose of the disease. The medical records of 64 children, who visited Wonkwang University Hospital from 2005 to 2015 for fever of undetermined origin, were analyzed retrospectively. Serum ADA levels were measured and indirect immunofluorescence antibody (IFA) assays were conducted. The patients were divided into two groups based on diagnosis of scrub typhus. Of 64 febrile patients, 39 were confirmed to have scrub typhus. Mean serum ADA level in the scrub typhus group (58.54±2.82 IU/L) was significantly higher than that in the non-scrub typhus group (29.30±4.03 IU/L, p<0.05). In the 25 non-scrub typhus patients, mean serum ADA level was significantly higher (50.24±8.52 IU/L) in patients with Mycoplasma infection than that in those with other diseases (19.46±1.39 IU/L, p<0.05). The study shows that in patients with only fever who are difficult to diagnose, serum ADA levels substantially aid the diagnosis of scrub typhus. Ed:- please consider carefully
