Purpose: The golden ratio has been used for a long time to objectify and quantify 'beauty'. Dr. Marqurardt claims that the golden ratio can be applied in the maxillofacial field as well. The purpose of this study was to evaluate the diagnostic significance of using a facial 'phi' mask for analyzing Korean faces with characteristics of Class I, II, and III malocclusion. Methods: We studied twenty five Korean celebrities' frontal facial photos (10 males, 15 females) and 90 malocclusion patients' frontal facial photos (30 patients in each malocclusion classification: Class I, Class II, and Class III). Patients who received orthodontic treatment at Samsung Medical Center were selected for this study. After superimposition of the selected facial photo and facial 'phi' mask using Adobe Photoshop CS3, the ratio of the entire facial area, mid facial area, lower facial area and horizontal and vertical lengths were measured. Results: The facial ratio in photos of Korean faces showed larger vertical and horizontal ratios than the facial 'phi' mask with golden ratio, regardless of skeletal malocclusion (entire face: 115%, lower face: 125% larger than the mask). The results of the frontal photos of Class I, II, and III malocclusion patients using facial 'phi' mask showed that the vertical length and frontal face area was more significantly influenced by the area of the lower face than the midface. This means that the lower face has larger proportions in the facial areas. Conclusion: The ratio of facial 'phi' mask is matched with the ideal facial appearance that the contemporary Korean general public is seeking. Thus, the facial 'phi' mask may be a convenient tool for esthetic analysis of Korean faces. Reducing the area of the lower face is esthetically more desirable for almost all Korean people when planning orthognathic surgery.

This study was done to define nursing diagnose and to test the validity of the characteristics for patients with cerebrovascular accidents being seen at home by home health care nurses. This study was a descriptive study. The sample consisted of 10 experts(professors and home health care nurses) who had had a variety of experience using nursing diagnoses in clinical practice, and 336 nurse progress notes for 18 patients with cerebrovascular accidents. First, 32 nursing diagnoses were defined by the analysis of 336 nurse progress notes, and ten nursing diagnoses were selected according to a criteria of frequency and four nursing diagnoses from home health care clinical practice. Second, content validity was examined by an expert group which considered the sign / symtoms of the fourteen nursing diagnoses. The instrument used for this was a checklist for sign / symtoms based on the nurse progress notes and literature : Carpenito(1993), Kim Cho Ja et al (1994), Lee Sun Ok et al.(1994), Kim Mae Ja et al. (1992), Seoul University Hospital (1993) , Kim Mi Ja et al. (1991). The data were collected from March 1995 to April 1995. Data were analyzed using Content Validity Incidence where if 80% or more of the expert group agreed, characteristics were defined as a major sign/symtoms, if between 50% and 79% of the expert group agreed with the characteristic it was defined as a minor sign / symtoms. The results of this study are summarized as follows : 1. Thirty-two nursing diagnoses related to patients with cerebrovascular accidents were defined. There was a high frequency for the following : 'Potential for disuse syndrome (61%)', 'Impaired physical mobility(50%)', 'Impaired skin integrity (44.4%)', Potential for aspiration(33.3%)', 'Potential for infection: respiration(33.3%)', 'Self-care deficit : bathing /hygine(27.8%)', 'Ineffective family coping(22.2%)', 'Potential for trauma(22.2%)', 'Alteration in nutrition: less than body requirements(22.2%)'. The following diagnoses were also used in home health care clinical practice : 'Anxiety in family (50%)', 'Caregiver fatigue(27.8%)', 'Ineffective treatment behavior (22.2%)', 'Ineffective Levin tube management and Levin tube feeding(22.2%)'. Fourteen nursing diagnoses were selected. 2. Ten of the nursing diagnoses for patients with cerebrovascular accident were listed as nursing diagnoses by NANDA but four nursing diagnoses were new nursing diagnoses used in home health care clinical practice. 3. Characteristics of the ten Nursing Diagnoses from NANDA were developed from the sign /symtoms in the literature and in the nurse progress notes. These characteristics was verified as major or minor sign / symtoms by the expert group. 4. Characteristics of the four nursing diagnoses used in home health care were not defined by the literature but only by the nurse progress notes and verified as major or minor signs /symtoms by the expert group. On the basis of the findings of this study, the following recommendations are made : 1. Continual study is necessary to identify other signs /symtoms not verified in this study. 2. It is necessary to use verified signs /symtoms in home health care clinical practice. 3. It is necessary to define related factors which define each diagnoses in this study. 4. It is necessary to develop of standardized nursing are plans which include defined signs and symtoms. 5. It is necessary to study the outcomes of the standardized nursing care plans.

Background : The treatment for multi-drug resistant tuberculosis(MDRTB) is encountered to be important clinically, but there are still a few reports about it all over the world. So, we evaluated the outcomes of only chemotherapy for the pulmonary MDRTB retrospectively. Method: We reviewed the clinical courses of 63 patients with pulmonary disease due to M.tuberculosis resistant to rifampin and isoniazid who were under follow-up between March 1996 and June 1996 after hospitalization at our hospital between January 1993 and January 1996. We performed cohort retrospective study for all these patient's records. Their regimens were selected individually and preferably included four medications that they had not been given previously and to which the strain was fully susceptible. Results: The 63 patients(mean age, 43.2 years) had previously received a median 5.1drugs. Fifty two(82.5%) patients responded to chemotherapy(as indicated by negative sputum cultures for at least three consecutive months) ; eleven patients(17.5 %) had no response, as shown by continually positive cultures. In a univariate analysis, an unfavorable response was significantly associated with greater number of resistant drugs before the current courses of therapy(relative risk 21.5 ; 95 percent confidence interval, 1.2-3.0; p<0.05). The mean period of follow-up was seventeen months. There was no relapse suooequently among the patients with responses. There was no death related to tuberculosis. Conclusion: In this report from National Masan Tuberculosis Hospital in Korea, multi-drug resistant pulmonary tuberculosis responded relatively well to carefully selected regimens.

To evaluate the treatment outcome after conservative treatment in patients with osteoarthritis of the TMJ(OA), the subjects were chosen among the patients who presented to the Department of Oral Medicine of Pusan National University Hospital, diagnosed as osteoarthritis of the TMJ, and treated with conservative methods from 1994 to 2006. 101 patients with diagnosis of osteoarthritis of the TMJ were selected as the experimental group and 74 patients with diagnosis of masticatory muscle disorders(MMD) were selected as the control group. Subjective symptoms and clinical findings were investigated to evaluate and compare the subject's status at the first and the last visit. The results were as follows : 1. In the OA group, satisfactory treatment outcome was obtained with conservative methods. But, at the last visit, the symptoms of the OA group were not improved enough compared with those of the MMD group. 2. In the OA group, radiographic findings of panorama view and transcranial projection were positive by about 60 percent. But, computed tomography and single photon emission computed tomography were positive by more than 90 percent. 3. At the last visit of the OA group, the joint noise was reduced significantly. 4. In the majority of the OA group, satisfactory treatment outcome was obtained with conservative methods such as medication, physical therapy, and occlusal stabilization appliance. In the majority of the MMD group, satisfactory outcome was obtained with medication and physical therapy. 5. It took the OA group from 6 months to 2 years to be cured well while the MMD group within 6 months.6. The OA group needed more than 10 times' treatment for satisfactory outcome while the MMD group needed less than 10 times' treatment.

The purpose of this study was to compare skeletal maturity index and dental developmental stages based on skeletal malocclusion. A total of 192 patients (89 male and 103 female) between 6 to 14 years old were selected for this study and underwent cephalograms, panorama radiographs, and hand-wrist radiographs. Any syndromic cases were excluded. Selected clinical parameters were dichotomised for statistical analysis. Chi-square, logistic regression analysis, and independent t-tests were used for the statistical evaluation. Canine, first molar, and second molar calcification were significantly associated with skeletal maturity in the logistic regression model (p < 0.05). In addition, patients who had higher skeletal maturity index were 11.43 times more likely to be female than those who had lower skeletal maturity index (p < 0.001). The patients with skeletal class II malocclusion displayed significantly higher dental developmental stage in canines, first premolars, first molars, and second molars than the patients with class III malocclusion (p < 0.05). The dental developmental stage of the patients was significantly associated with skeletal maturity. In addition, there was a significant difference between class II and class III malocclusion with some types of tooth calcification.

Recognition of the usefulness and the importance of the nursing diagnosis is increasing. There is a prevailing opinion that nursing diagnosis should be used to improve the quality of nursing care. Developing standardized nursing care palns based on nursing diagnoses is therefore considered one of the most essential projects for professional growth and improvement in the nursing world of Korea. Consequently, in the first stage of this research project, the ten nursing diagnses used most frequently with patients on medical and surgical wards were determined and related nursing care plans were developed, implemented and evaluated. The application of the standardized nursing care plans raised the nurses' confidence and proved to be effective in enhancing the quality of nursing care. This study was initiated as the next stage, to develop, test, and determine the validity of nursing care plans for the remaining nursing diagnoses. Nineteen medical and surgical wards were selected for the study ; the 176 staff nurses working on those wards and 1211 patients hospitalized there (603 patients during the nursing care plan use) took part in the project. The following summarizes the results of the study : 1. After listing all the nursing diagnoses up to the 20th in frequency from each ward except the ten used in the first study, 22 nursing diagnoses were selected. Two related to ‘self care deficit’, were combined into one. Standardized nursing care plans were established for these 21 nursing diagnoses. 2. The first page of each nursing care plan lists the related factors and defining characteristics as supporting data. The application rate distribution revealed that the majority were recorded less than 50% of the time. For each nursing diagnosis, only one to three related factors were recorded more than 50% of the time regardless of the number of suggested related factors, and similarly, only one to five defining characteristics were recorded more than 50% of the time regardless of the number of suggested defining characteristics. Therefore, these factors and defining characteristics were proposed as the common related factors and the typical signs and symptoms for each nursing diagnosis. 3. The application rate distribution for the expected outcomes, and the nursing orders that were the main data of each nursing care plan occurred more than 50% of the time, unlike the related factors and the characteristics that occurred less frequently. These findings supported the clinical validity. 4. In an effort to evaluate indirectly the effect of the use of the standardized nursing care plans, nurses' job satisfaction and perceptions of their ability in the use of the nursing process were measured and compared. Scores after the use of the plans were significantly higher than those before. The experience in actually using the standardized nursing care plans with patients increased the nurses' professional and emotional satisfaction and their confidence in using the nursing process. Also when the nurses who actually used the nursing care plans were asked to rate their effectiveness, the highest score was given to ‘the ease of establishing the nursing goal’, followed by ‘improved professional advice and care for patients’, ‘the efficiency and systemization of charting’, ‘the definite recognition of the nursing problem’, and ‘the selection of effective and appropriate nursing interventions’ in descending order. The results indicate the nurses were very positive about the effect of the real clinical application of standardized nursing care plans, and that the objective of this study to utilize the nursing diagnosis to strengthen the nursing process was attained.

This study attempted to evaluate the usefulness of the air mattress by analyzing the subjective comfort of the patient due to the application of the air mattress to the table of computed tomography through a questionnaire and analyzing the change in image quality through quantitative and qualitative evaluation of the patient's clinical images. The subjects who participated in the study were 221 men and 229 women, and the age range was from 18 to 86. To evaluate the change in image quality, a total of 150 patients, 50 patients per group, were selected for quantitative evaluation, and 20 patients per group, a total of 60 patients were selected for qualitative evaluation. As a result of this study, the subjective comfort of patients increased due to air mattresses, and there was no difference in image quality as a result of quantitative and qualitative evaluation of clinical images. From the above results, it is believed that the air mattress can be usefully applied in a way that can increase the subjective comfort of the patient without any harm to the diagnostic image.

The purpose of this study was to identify risk factors predictive of alterations in skin integrity during the intraoperative period. The predictive risk factors were studied for intraoperative pressure sores from December 1998 through January 1999. A sample of 220 patients was selected from the operating room schedule of a University Hospital in Pusan. There were two criteria in including patients : the operation lasted longer than 2 hours and the absence of skin break-down according to NPUAP criteria. The data were analized by SPSS/PC, Stepwise multiple logistic regression was used to identify the variables which were predictive of alterations in skin integrity. Of the 220 patients studied, 41 patients (18.6%) developed stage 1 pressure sores in the immediate postoperative period. In relation to skin changes, three independent variables emerged from the stepwise multiple logistic regression as being significant (p<0.05). Factors predictive of pressure sore formation included low serum albumin(p=0.000), prone position while undergoing surgery(p=0.0004), time on the operating table(p=0.0165). Among the intrinsic factors, serum albumin was the most significant causal factor in pressure sores development in the intra-operative period. Pressure and shearing force were the most significant extrinsic factors in pressure sores development. From the results of this study we concluded that the primary nursing goal is the maintenance of the proper patient' position during the intraoperative period. Also imperative for sore prevention is the reduction of surgery time and improving preoperative nutritional status.

A clinical study of selected patients with intraoral squamous cell carcinoma which were managed in the Department of Oral Oncology of Korea Cancer Center Hospital from January 1982 to August 1989 was done. And following results were obtained. 1. Males were involved more than females by intraoral squamous cell carcinoma in a ratio of 4:1. and most of the cases occurred in the 7th and 6th decades (69%). 79% of total patients and 92.5% of males were. 2. The mean duration of symptomatic period was 5.9 months. 3. The common symptoms were swelling (63%), pain (40%), ulceration (33%), and trismus (23%) 4. In the histologic findings, well differentiation comprised 58.0%. 5. The primary sites were the upper alveolar mucosa (32%), the floor of the mouth (21%), the lower alveolar mucosa (19%), tongue (14%), retromolar trigone (8%), palate (7%) and buccal mucosa (3%). 6. According to TNM system, Stage I, Stage II, Stage III, and Stage IV comprised 4%, 15%, 32%, and 49% respectively. 7. In the management of intraoral squamous cell carcinoma, surgeries were done in the 32 cases, 23 cases of which were managed by radiation therapy or chemotherapy concurrently. And radiation therapy alone was received in 35 cases. 8. Overall 3 and 5-year survival rates without regarding to stage were 27.6% and 21.4%. 9. 3-year survival rate of female patients was 47.2% and that of male patients was 22.6%. 10. 5-year survival rate was 53.9% for "early" cancer (stage I and II) and 15.6% for "advanced"cancer (stage III and IV). Survival rate of patients in the early stages of cancer appeared to be higher than that of patients with stage III and IV(p<0.05).

Aims and Background: Human leukocyte antigen-G and interleukin-2 receptor play pivotal roles in the proliferation of lymphocytes, and thus generation of immune responses. Their overexpression has been evidenced in different malignant hematopoietic diseases. This study aimed to validate serum soluble human leukocyte antigen-G (sHLA-G) and serum soluble interleukin-2 receptor (sIL-2R) as an additional tool for the diagnosis and follow up of acute lymphoblastic leukemia (ALL). Subjects and Methods: Both markers were determined by ELISA in the serum of 33 ALL pediatric patients before treatment and after intensification phase of chemotherapy as well as in the serum of 14 healthy donors that were selected as a control group. Results: ALL patients showed abnormal CBC and high serum lactate dehydrogenase, which were improved after chemotherapy. Also, there was a non-significant increase in serum sHLA-G in ALL patients compared with the control group. However, after chemotherapy, sHLA-G was increased significantly compared with before treatment. On the other hand, serum sIL-2R in ALL patients was increased significantly compared with the control group. After chemotherapy, sIL-2R decreased significantly compared with before treatment. Conclusions: From these results it could be suggested that measurement of serum sHLA-G might be helpful in diagnosis of ALL, while sIL-2R might be useful in diagnosis and follow-up of ALL in pediatric patients.
