BACKGROUND: The length of postoperative drug therapy remains controversial in pulmonary tuberculosis. We analyzed our experiences to determine the postoperative duration of chemotherapy after resection. METHODS: A retrospective review was performed in 66 of 95 patients that underwent pulmonary resection for pulmonary tuberculosis between January 1993 and December 1998. We compared the relapse rates according to the length of postoperative chemotherapy in each group, classified by the results of sputum AFB culture before the surgery, the number of resistant durgs, the number of prior treatment and the division of anti-TB drugs used postoperatively. RESULTS: Fifty three of 66(80.3%) were men and 13(19.7%) were women with a median age of 33.5 years(range, 16 to 63). The mean lengths of the pre-and post-operative chemotherapies were 4.9 months, and 12.9 months respectively. Five of 66 patients(7.6%) relapsed during the mean period of follow up(39.7 months). In the group less than three times of the prior treatment, there were two relapses(20%) in Ed-the highlight above-rephrase 10 patients that were medicated for 6 months or less, and one relapse in 43 patients(2.3%) that took medicine for more than 6 months(p=0.03). In the group using second-line drugs postoperatively, there was one relapse(25%) in four patients that were medicated for 12 months or less. No patient in a total of 17 that received medicine for more than 12 months relapsed(p=0.03). CONCLUSION: We recommend that patients with the prior treatment less than three times should be treated for more than 6 months after resection and patients using the second-line drugs postoperatively should be medicated for more than 12 months.

The purpose of this study is to build up the foundation to prepare the effective nursing intervention devices for the seriously ill patient's families nursing through the nurse understanding of the experiences of the seriously ill patient's families in the field by setting up grounded theory. In this study, the subjects is the 6 families members of ICU patients, who were being cared in university hospital and the data were collected from 4.15 to 5, 1996 by the recordings and transcring the interview. The intervention lasted from 2 hours to 2 and a half hours. The data were analyzed in the framework of grounded theory as mapped out by Strauss & Corbin. The core category in the analysis of the experiences of the families of the seriously ill patients was the process of setting the "distress". In the process of datas analysis, the categories were 19 conceptions-'serious', 'bad', 'fear', 'press', 'hearburn', 'impatient', 'insufficient', 'change of patients' status', 'economic ability', 'family relationship', 'whilled power', 'request', 'direct caring', 'passive effort', 'control', 'receive', 'tired', 'blame'. These categories were again grouped into 12 categories, including 'exigency', 'overwhelming', 'worry', 'change of status', 'economic ability', 'relationship', 'caring will' 'active caring', 'passive response', 'accept', 'exhaustion', 'blame'. In the above mentioned categories, 'overwhelming' and 'worry' were categorized into the "distress!". On the basis of the patterns that have emerged on process of data analysis, the five below were confirmed. (1) When the patient's status is worse and economic ability is bad and the family relation to the patient is close and the distress is expressed with active caring willness is strong, the distress is expressed with active caring and brings about accept and blame. (2) When the family relation to the patient is distant and the distress decrease and the subject's caring willness is weak, the distress is expressed with passive response and brings about accept and exhaustion in spite of the patient's status is worse and bad economic ability. (3) When the patient's status is worse and economic ability is bad and the family relation to the patient is close and the distress increase, the subject's caring willness is strong, the distress is subject's caring willness is strong, the distress is expressed with passive response and brings about accept and exhaustion. (4) When the patient's status is improve and economic ability is good and the distress decrease and the subject's caring willing is strong, the distress is expressed with active caring and brings about accept and blame in spite of the family relation to the patient is close. (5) When the patient's status is improve and economic ability is bad and the family relation to the patient is close and the distress increase, the subject's caring willness is strong, the distress is expressed with active caring and brings about accept and blame.

PURPOSE: The purpose of this study is to identify the correlation that exists between quality of life and self-efficacy of schizophrenic patients, focusing on the influence of related factors on these varables. METHOD: The subjects of this study were 151 schizophrenic patients. The data were collected using questionnaires. The instruments used for this study were the general self-efficacy scale developed by Sherer & Maddex (1982), the specific self-efficacy scale modified and complemented by these co-researchers on the basis of the past studies and modified SIP by Voruganti (1996). The period of data collection was from July. 2000 to Jan. 2001. Data analysis was done by SPSS, t-test, ANOVA and the Pearson Correlation Coefficient. RESULT: 1. The level of self-efficacy showed a mean score of 60.0 and the level of quality of life, a mean score of 47.0. 2. The general characteristics affecting the self-efficacy of schizophrenic patients were staying with family (p=0.05) and employment (p=0.00). 3. The general characteristics affecting the quality of life of schizophrenic patients were staying with family (p=0.04), employment (p=0.05) and duration of illness (0.03). 4. A positive correlation was identified between self-efficacy and quality of life (r=-0.469, p=0.000). CONCLUSION: The study suggests that nursing intervention strategy should be worked out to develop a psychiatric rehabilitation program that can promote self-efficacy and thus enhance the quality of life of schizophrenic patients.

Body surface potential map, an electric potential distribution on the body torso surface, enables us to infer the electrical activities of the heart. Therefore, observing electric potential projected to the torso surface can be highly useful for diagnosing heart diseases such as coronary occlusion. The BSPM for the heart of a patient show a higher level of sensitivity than 12-lead ECG. Relevant research has been mostly based on clinical statistics obtained from patients, and, therefore, a simulation for a variety of pathological phenomena of the heart is required. In this study, by using computer simulation, a body surface potential map was implemented according to various occlusion locations (distal, mid, proximal occlusion) in the left anterior descending coronary artery. Electrophysiological characteristics of the body surface during the ST segment period were observed and analyzed based on an ST isointegral map. We developed an integrated system that takes into account the cellular to organ levels, and performed simulation regarding the electrophysiological phenomena of the heart that occur during the first 5 minutes (stage 1) and 10 minutes (stage 2) after commencement of coronary occlusion. Subsequently, we calculated the bipolar angle and amplitude of the ST isointegral map, and observed the correlation between the relevant characteristics and the location of coronary occlusion. In the result, in the ventricle model during the stage 1, a wider area of ischemia led to counterclockwise rotation of the bipolar angle; and, during the stage 2, the amplitude increased when the ischemia area exceeded a certain size.

The Korean Journal of Orthodontics 2014;44(2):77-87
OBJECTIVE: This study was designed to define the Korean norm values for the Ricketts analysis. METHODS: In this longitudinal study, lateral cephalograms of 31 subjects with normal occlusion were taken biennially from ages 9-19 years. Cephalometric measurements were performed. Parameters for which the 10-year change did not exceed one standard deviation were defined as unchanged. The means and standard deviations for the measured parameters were determined for each age group. RESULTS: No significant changes in growth were observed in the molar relationship, incisor overjet, incisor overbite, mandibular incisor extrusion, interincisor angle, lower incisor tip (B1) to A point-Pogonion (A-PO) plane, upper incisor tip (A1) to A-PO plane, B1 inclination to A-PO, A1 inclination to A-PO, B1 inclination to Frankfurt plane (FH), convexity, lower facial height, facial axis, maxillary depth, maxillary height, palatal plane to FH, cranial deflection, ramus Xi position, or porion location. Continual changes over the 10 years of growth were observed in the maxillary first molar distal position to pterygoid true vertical plane, facial depth, mandibular plane to FH, anterior cranial length, mandibular arc, and corpus length. CONCLUSIONS: Clinicians can apply the Korean norms at age 9 as determined in this study when using the Ricketts analysis. The patient's age at the beginning of treatment and their sex should be taken into consideration when drawing visual treatment objectives.

The origin of osteoclast-like giant cell tumor (OGCT) of the salivary gland has been debated because the prototypic cells of osteoclast-like cells and mononuclear stromal cells are largely unexplained in this gland. Bone marrow-derived CD14+ and CD45+ monocyte-derived multipotential cells (CD14+/CD45+ MOMC) may be one of the possible origins of OGCTs of salivary glands, which have never been explored in salivary OGCTs. We present a case of OGCT accompanied with carcinoma ex pleomorphic adenoma in the parotid gland of a 67-year-old Korean female. The tumor presented as a rapidly growing cervical mass comprising a central area of carcinoma ex pleomorphic adenoma and a peripheral circumferential area of OGCT. The immunohistochemical staining pattern was phenotypically consistent with bone marrow-derived CD14+/CD45+ MOMC. This case is the first report of a salivary OGCT in Korea.

10.The Graft Outcomes of Living Donor Renal Transplantation according to Gender, Age, and BMI Matching between Donors and Recipients.
The Journal of the Korean Society for Transplantation 2010;24(3):204-209
BACKGROUND: Despite significant advances in immunosuppression, supportive therapies, and operative skills, several factors still compromise long-term graft survival of patients who undergo renal transplantation. This study was designed to evaluate the risk factors influencing graft outcomes of living donor renal transplantation. We matched the recipient and donor age, gender, and body mass index (BMI). METHODS: A total of 527 living renal transplantations were evaluated. The patients were divided into matching groups by donor and recipient age; group 1 (50< or =/; 2, 50< or =/<50; 3, <50/50< or =; 4, <50/<50), gender (A, female/female; B, female/male; C, male/female; D, male/male), and BMI ratio (recipient/donor) (I, <0.8; II, 0.8< or =/<1.3; III, 1.3< or =). We compared 1, 3, 5, and 10 year graft survival and analyzed the donor and recipient variables of age, HLA matching, and acute rejection. RESULTS: The risk factors affecting long-term graft survival were recipient gender, acute rejection rate, and HLA-AB matching. In the groups divided according to donor and recipient age, no statistical difference was observed among the groups, but the 3-5 yr graft survival of group 1 (94.1/86.9%) was much higher than group 2 (86.5/75.6%). In the groups divided according to donor and recipient gender, graft survival in group C was higher than that in the other groups. No statistical difference in acute rejection or graft survival were observed in the groups with different BMI ratios. CONCLUSIONS: Meticulous preoperative donor and recipient matching for living renal transplantation may improve graft survival and expand the donor and recipient pool.
