  • Objectives: Leiomyosarcoma is a malignant neoplasm that affects smooth muscle tissue and it is very rare in the field of oral and maxillofcial surgery. The purpose of this study was to obtain information on diagnosis of and treatment methods for leiomyosarcoma by retrospectively reviewing of the cases. Patients and Methods: The study included nine patients who were diagnosed with leiomyosarcoma in the Department of Oral and Maxillofacial Surgery at Seoul National University Dental Hospital. The subjects were analyzed with respect to sex, age, clinical features, primary site of disease, treatment method, recurrence, and metastasis. Results: Particular clinical features included pain, edema, mouth-opening limitations, dysesthesia, and enlarged lymph nodes. All cases except one were surgically treated, and recurrence was found in two cases. Four of nine patients were followed up without recurrence and one patient underwent additional surgery due to recurrence. Conclusion: In our case series, notable symptoms included pain, edema, mouth-opening limitations, and dysesthesia; however, it was difficult to label these as specific symptoms of leiomyosarcoma. Considering the aggressive characteristics of the disease and poor prognosis, surgical treatment is necessary with careful consideration of postoperative radiotherapy and chemotherapy.

  • This study was carried out with two types of silkworm, Bombyx mori, adults having different life span: long life span (adult living for more than fifteen days; LLS), and short life span (adult living less for than five days; SLS). The fine structures of fat body cells in the young and the senescent males and females were compared in an attempt to elucidate the aging physiology of the silkworm adult. In SLS, there were many rough endoplasmic reticula (RER) and glycogen granules in the female cytoplasm, whereas the smooth endoplasmic reticula (SER) were observed in the male cytoplasm. Also in SLS, the mitochondria were swollen and had many poor osmiophillic inclusions (fatty degeneration) at three days after emergence. In LLS, compared to SLS, comparatively normal mitochondria and nuclear membrane were observed in even five day old female. In fifteen day old LLS female, however most of cell membranes were disappeared and mitochondria were abnormally expanded. Many fat granules were observed in the cytoplasm of ten day old male (LLS) which died with full autophagic vacuole (AV) collapsed at fifteen days. Therefore, it is suggested that SLS type is recommended for the study of aging tissue, because it is easier to monitor the changes in tissue structure.

  • The purpose of the study is to examine the effect of the spring shoe through the comparison of spring shoe to general shoe. For this, 12 healthy females in the age from 20 to 30 years participated in the E.M.G. experiment with testing kinematic variables. Results indicated that there was significant differences in angle of ankel between the general and spring shoe. Specifically, the spring shoe showed a bigger angle of take on and a smaller angle of take off in walking than the general shoe. This mesns that the spring shoe does not have a significant effect to produce efficient and smooth walking. In addition, the spring shoes revealed a bigger rear-foot angle than the general shoe in the evaluation of rear-foot control function. This means that the rear-foot control function of the spring shoe is low compared to trhe general shoe. Meanwhile, there is no significant differences in angle of knee and angle of Achilles tendon between both shoes. In an analysis of E.M.G., the significant differences were found in gastrocnemius muscle, anterior tibial musculi, musculi rectus femoris, biceps muscle of thigh between both the general and spring shoe groups by the section. In the case of gastrocnemius muscle, the spring shoe showed a low muscle production of anterior tibial musculi than the general shoe. This is a result from structural nature of the sole of a foot of the spring shoe. The spring shoe performs a rolling movement through slightly large pronation toward front-foot from rear-foot in supprt time before taking-off of toe and the power for this movement is mainly produced from musculi rectus femoris.

  • Lymphangioleiomyomatosis is a rare disease which afflicts young women of childbearing age. We experienced a 32-year-old female who was admitted because of worsening exertional dyspnea after hormonal therapy with Clomifen for five months and intermittent hemoptysis. Chest PA showed diffuse ground glass appearance with some reticular infiltrations. High resolution CT scan showed multiple small thin walled cysts distributed homogeneously throughout the entire lung. Pulmonary function test showed characteristic obstructive pattern despite the restrictive interstitial pattern of chest radiography. Thoracoscopic lung biopsy specimen showed abnormal proliferation of smooth muscle cells in the walls of lymphatic vessels, bronchioles, and pulmonary vessels typical of pulmonary lymphangioleiomyomatosis. Hormonal therapy with medroxyprogesterone was initiated.

  • Purpose: The stability of periodontal condition and marginal bone level were important to achieve long-term success of dental implant treatment. The aim of this study was to evaluate periodontal conditions and marginal bone loss around 67 GSII(OSSTEM, Seoul, Korea) dental implants with dual-microthread at the neck portion, 1 year after prosthetic loading. Materials and methods: Sixty-seven GS II dental implants in 27 patients(mean age; $47.4{\pm}14.0$ years) who received implant treatments at Pusan National University Hospital, were included in this study. Thirteen US II(OSSTEM, Seoul, Korea) implants with smooth neck design were selected for the control group. Periodontal and radiographic evaluations were carried out at baseline, 6 months and 12 months after prosthetic loading. Results: In the GS II group, plaque index(PI), gingival index(GI) and probing depth(PD) increased as time passed. In the US II group, GI and PD increased. Although marginal bone level was lower in the US II group in all evaluation periods, the changes between the periods were not statistically significant(p>0.05). In each period, periodontal parameters were not statistically significant between groups. Conclusion: One year after prosthetic loading, GS II and US II dental implants showed similar periodontal conditions and marginal bone response, and were within the criteria of success.

  • Forming health care management model in small-scale enterprises was the purpose of this study. For the purpose, we tried to investigate the characteristics of small-scale enterprises and analyzed the pattern of their health care management. The results are as follow: 1. The strength of health managing agency and technical supporting program lies in team approach by specialized manpower. However, if the liaison between each part of the organization is not smooth, the overall management will be very difficult. 2. Small scale enterprises are characterized by their short life after the establishment, use of rental building, lack of welfare facilities, weakness in sanitary management and aggregation of factories of similar type of industry. Because of these characteristics, it is very difficult to solve problem basically, such as improvement of working environment. Therefore, it is important to focus on health education and community based approach. 3. Many workers in small-scale factories are in middle and old age. They have health problems mainly related to personal habits. Implementation of an appropriate health promotion program is needed. 4. The number of workplaces, which should be managed by health managing agent. is increasing rapidly. But the number of health managing agent is limited. In the aspect of the requirement of manpower and equipment, training personal agent is more urgent than founding institutional agent. 5. The uniform method of health management hampers the choice of employer and workers. The types of provision of health management should be diversified. 6. For an efficient management, a frequent visit of personal agent and the following referral to a specialist should be done. The specialists in charge of secondary management are from the field of occupational medicine, occupational hygiene, ergonomics, etc. 7. The health management of small-scale facilities should have six components. They are community-based approach, multi-disciplinary cooperative system, program based on the need of recipient, forming partnership of employer and worker, change of lifestyle, and evidence-based program.

  • Background: Adult patients with intellectual disabilities often strongly resist the anesthetic administration for dental procedures. This study aimed to evaluate the effect of midazolam premedication in improving the cooperation level of patients who are likely to be combative and irritated during general anesthesia (GA) induction. Methods: The patients who had received dental treatment under ambulatory GA for more than two times were included. And we selected 13 patients total that needed physical restraint or ketamine IM prior to induction at the first GA, and were prescribed midazolam tablet (7.5-15 mg) at the following GA. We reviewed pre-anesthetic records and anesthesia records, and evaluated cooperative levels of patients (4 levels scale) during anesthesia induction and recovery time retrospectively. Results: All 13 patients (Male 11, Female 2) had severe mental disabilities. The average age of the patients was 24 ${\pm}$ 7 (13-37) years and their average weight was 58 ${\pm}$ 16 (34-91) kg. At the first GA, 10 patients needed physical restraint prior to induction (level 3). And 3 patients were so poorly cooperative that the induction procedure was performed after intramuscular injection of ketamine (level 4). But after the midazolam intake, 7 patients were willing to receive the anesthetic induction (level 1, 2), and 6 patient needed physical restraint (P < 0.05). There were no statistical differences in the duration of general anesthesia and postoperative recovery. Conclusions: Oral intake of midazolam was effective in improvement of cooperation without any complications.

  • The Oriental flower arrangements have the beauty of a strict triangle in a symmetrical three-dimensional effect as the form of flower tribute to gods in ancient times and used frogs to fix flowers to a basin easily. Flower arrangements of a conical shape made by repeatedly piled flowers in ancient Egypt shows the origin of the present vertical form of the Western flower arrangements. Flower arrangements in ancient Greece formed in a smooth S shape, while Roman flower arrangements were rich and gorgeous in a lowering and thin shape horizontally. Persians were showing triangular forms similar to the Oriental three-dimensional effect. The basic form of flower arrangements in the age of Renaissance was also created upon the ancient one, descending to Art Nouveau when flower arrangements were widely expressed from mass to space aesthetics led by America in the 20th century influenced by mild color, simplicity and realistic description of the Oriental art in the late 19th century. The Western flower arrangements are focused on formation, same as the Oriental ones, yet they disregard naturality and based on practicality.

  • Purpose: The purpose of this study is to introduce a tool for evaluating eye movement and analyze the reliability of measurement based on 10 cases of evaluating the oculomotor function of children with spastic cerebral palsy Methods: The participants were selected by 6 medical and welfare institutions in Busan as GMFCS grade 1-3 among spastic diplegia and hemiplegia. Seven examiners evaluated 3 children for the evaluation of inter-rater agreement of Ocular Motor Score (OMS) and evaluated the condition of the ocular motor of 10 children using OMS, a re-examination was performed at six weeks after the initial examination. SPSS ver.25.0 was used to calculate the interclass correlation coefficient and Wilcoxon's signed-rank test, Mann Whitney-U test. Results: The inter-rater agreement of OMS was 0.89. Second mean values were decreased compared first examination in motility/ductions/version, saccades and smooth pursuit, but there was no significant difference. Children under 6 years old had a high mean value of saccades in first examination and the motility/ductions/version, fixation, saccades in second examination, but there was no significant difference. Spastic diplegia children's mean values were higher in head posture, fixation in 8 gaze directions than hemiplegia children in both first and second examination, but there were no significant differences. Conclusion: Ocular motor function in 10 children of spastic children who participated in the study and could see that the scores was differed depending on age, type, grade of cerebral palsy. OMS may be available for this purpose.
