Purpose : The purpose of the current study was to report the results of curettage and en bloc excision as well as to introduce how to excise the nidus percutaneously with Halo-mill. Material and Methods : Twenty patients(14 men and 6 women) were evaluated, who had operative treatments after diagnosed as osteoid osteoma from March 1990 to January 1998. These patients ranged in age from 7 to 42 years(average: 20.8 years). Locations were 9 femurs, 6 tibias, 2 vertebras, 1 ulna, 1 maxilla and 1 skull. Nine femoral lesions included 5 proximal metaphysis, 2 neck and 2 diaphysis, while 5 tibial lesions included 3 diaphysis, 1 proximal metaphysis and 1 distal metaphysis. We used simple radiography, bone scan, CT and MRI for the accurate diagnosis and localization. As for surgical treatments, while excision and curettage had to need open-exposure of lesion, the percutaneous excision of nidus did not need openexposure : guided Halo-mill into K-wire inserted to nidus under image intensifier. Results : Simple radiography showed that 10 cases had typical nidus and others had only cortical sclerosis. Bone scan was performed at 14 cases and all had hot uptake except one case. We used CT in 10 cases and MRI in 4 cases as diagnostic methods, of which 1 case didn't reveal nidus at CT. Surgical treatment consisted of 6 curettages, 11 excisions, 2 percutaneous excisions with halo-mill and 1 total elbow arthroplasty. We used 7mm sized Halo-mill. During the follow-up period, all patient relieved symptoms and there were no recurrences. All had histologically typical findings except one which had hyperostosis without nidus. Conclusion : Complete removal of the nidus is the most important factor in the treatment. We could excise the nidus percutaneously in 2 cases with the minimal injury to surrounding soft tissues. If we could evaluate the precise location, size of nidus and percutaneous acccesibility, the percutaneous excision of nidus with Halo-mill could be an alternative method as a treatment of osteoid osteoma.

This research was designed to evaluate the nutritional an microbiol quality assessment of Chungmukimbab purchased from market in Tongyeoung area. Contents of calories, calcium, iron, thiamin and riboflavin in ordinary kimbab and Chungmukimbab were lower than the recommended levels of Korean adult men. So, We suggested that a fruit, beverage and ffod stuff were supplemented to maintain nutritional balance. Total aerobic bacteria and coliform group of just prepared ordinary kimbab and Chungmukimbab samples from market were not significantly different, showing approximately $5.50{\pm}0.38 log_{10} CFU/g,\;2.10{\pm}0.47log_{10}MPN/100g$ in ordinary kimbab, $5.61{\pm}0.42log_{10}CFU/g,\;1.75{\pm}0.34 log_{10} MPN/100g$ in Chungmukimbab, respectively. Total aerobic bacteria of law ingredients of chungmukimbab sample were 3 to $4 log_{10}CFU/g$ in kimbab, seasoning squid and radish roots kimchi, 4 to $5 log_{10}CFU/g$ in boiled fish paste. The coliform groups were 1 to $2 log_{10}$ MPN/100 g in kimbab, seasoning squid and radish roots kimchi, 2 to $3 log_{10}$ MPN/100g in boiled fish paste. Detection rate of E. coli and Staphylococcus aureus counts were 10.0, 12.5% in Chungmu-kimbab, 15.0, 10.0% in seasoning squid, 0, 10.0% in radish roots kimchi respectively, not detected in boiled fish paste samples. During storage at $15^{\circ}C$ for 24 hours, total aerobic counts and coliform groups in ordinary kimbab and Chungmukimbab were increased by the 1.94, $0.97log_{10}CFU/g$, 0.60, 0.72 log10 MPN/100g respectively. Total aerobic counts of Chungmukimbab ingredients increased $0.83{\sim}l.33 log_{10}CFU/g$ at different time

Purpose Find out about the significance of the GFR values calculated by the kidney depth is measured by comparing the values obtained for kidney depth was measured GFR in the CT image kidney depth and is calculated by Tonnesen law in $^{99m}Tc$-DTPA dynamic kidney scan with each applies. Materials and Methods Among patients with normal value (75~120 mL/min) computed GFR conducted of dynamic renal scan to visit from February 2013 to February 2014 and donor GFR values in patients with normal value. The mean age was 46.9 years with 14 men 13 females. We used abdomen CT image which checked before conducting dynamic Kidney scan for measuring the depth of kidney. We only used CT image that contains renal hilum and measured outermost front of the kidney from the skin surface (a) and the final surface (b) caculated the average depth of [(a + b) / 2] respectively. Using the same ROI in order to limit the change in GFR values by the other additional element was set before and after the depth value was excluded from the GFR falls kidney disease. Results Using Tonnesen law the average value was caculated 5.94 cm from the right kidney 5.90 cm from the left kidney. It was 6.83 cm, 8.71 cm in the left kidney and the right kidney average value of the depth measured on the basis of the CT image. The respective increase in left kidney 0.93 cm and right kidney 2.77 cm calculated on the basis of CT image actually measured values. GFR was calculated as the average depth of the subject calculated by the method Tonnesen $83.3{\pm}9.79mL/min$. $98.6{\pm}14.07mL/min$ GFR was applied to calculate the average depth of the subjects using the CT image, is the difference appears 15.26 mL/min was increased after seting up depth value, P value was less than 0.01 which is significant. Conclusion The difference between GFR before-after setting up depth value cause that the different of depth value. Is a measured depth of the extension value of the calculated estimates Whereas Tonnesen kidney depth method is to use in calculating the value of GFR in a typical dynamic elongation test depth derived using the CT image depth. Is thought to be able to calculate more accurately the GFR value by the distance to the center of kidney more accurately measured in the skin thereby.

Metastatic bone tumor is the most common bone tumor and 32.5% of all primary malignant tumors are eventually metastasize to bone. Metastatic bone tumor has been more frequently encountered disease in the orthopedic fields due to the greater longevity of life of the patients with primary visceral cancers by major advances in early detection, diagnosis, and surgical/radiotherapeutic/chemotherapeutic treatment of primary and metastatic lesions. Therefore, the epidemiologic data about the incidences and the patterns of bone metastasis is important. We reviewed 417 patients who were diagnosed and treated for metastatic bone tumor at Kosin University Medical Center from 1985 to 1993 to analyse the primary lesion, age and sex distributions, location of bone metastasis, patterns of metastasis according to the primary. The results were as follows : 1. The common origin of bone metastasis were lung(29.5%), stomach(15.3%), breast(11.3%), unknown(7.7%), cervix(5.3%), liver(4.8%) in order of frequency. 2. There were 251 men and 166 women and their mean age was 54.8 years and the peak age incidence was in 6th decades. Most cases(85.3%) were occured beyond 5th decades. 3. The preferred sites of metastatic deposits were spine(64.0%), pelvis(40.5%), rib(38.8%), femur(36.7%), skull(21.1%), humerus(13.9%), scapula(13.0%) in order of frequency. In the spine, thoracic(42.1%), lumbar(39.1%), cervical(13.2%), sacral(5.6%) vertebrae were involved in order of frequency. 4. Multiple bone metastases were more common(73.1%) than single metastasis(26.9%). 5. In the lung cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, pelvis, femur. 6. In the stomach cancer, the peak age incidence was 6th decades, and the preferred sites of bone metastasis were spine, femur, pelvis. 7. In the breast cancer, the peak age incidence was 5th decades, and the preferred sites of bone metastasis were spine, rib, pelvis. 8. In the bone metastasis with unknown primary site, the peak age incidence was 7th decades, the preferred sites of bone metastasis were spine, femur, pelvis, and the common histologic types were adenocarcinoma and squamous cell carcinoma.

Objectives : Traditionally intracranial meningiomas are regarded as benign and curable tumors. About half of all intracranial meningiomas locate in the skull base region. However, surgical removal of these tumors may be challenging and require special considerations. Here general aspects of skull base meningiomas including clinical presentation, surgical approaches, complications and their recurrence rate are discussed based on our experiences. Methods : A retrospective analysis of 61 consecutive patients with skull base meningioma among 210 patients of meningioma between 1989 and 1998 were done. Results : There were 41 women and 20 men ranging from 13 to 74 years(mean 52 years). These tumors were divided into seven categories according to location : olfactory groove(n＝9), sphenoid ridge(n＝16), cavernous sinus(n ＝2), tuberculum sellae(n＝8), tentorium(n＝13), cerebellopontine angle(n＝12), and foramen magnum meningiomas (n＝1). Surgical approaches were selected on the basis of the tumor attachment, size and extension on preoperative radiologic findings. Total removal(Simpson grade I and II) was achieved in 50 cases(82%), and subtotal removal (Simpson grade III) in 11 patients(18%). According to WHO classification, there were 52 of cases of benign meningioma( 86%), 6 atypical cases(10%), and 3 malignant cases(5%). The most common postoperative complications were CSF leakage(23.0%) and cranial nerve injury(8.2%). Three patient died related with tumor(one was due to surgical complication and the other two due to recurrence) but three patients died from other systemic causes. Mean follow-up period was 51.7 months after surgery. Recurrence occurred in six patients(10.9%) ; three with tentorial meningioma, two with sphenoid ridge, and one in cerebellopontine angle. Conclusion : With advances in neuroradiology and microsurgical techniques, the surgical outcome of miningiomas has been markedly improved with acceptable morbidity and mortality rates. Overall, our surgical results of skull base meningiomas is comparable to other reports. Therefore, with the appropriate operative strategy and techniques, these tumors can be completely removed and good surgical results can be expected.

Objective : The intralaminar screw (ILS) fixation technique offers an alternative to pedicle screw (PS) and lateral mass screw (LMS) fixation in the C7 spine. Although cadaveric studies have described the anatomy of the pedicles, laminae, and lateral masses at C7, 3-dimensional computed tomography (CT) imaging is the modality of choice for pre-surgical planning. In this study, the goal was to determine the anatomical parameter and optimal screw trajectory for ILS placement at C7, and to compare this information to PS and LMS placement in the C7 spine as determined by CT evaluation. Methods : A total of 120 patients (60 men and 60 women) with an average age of $51.7{\pm}13.6$ years were selected by retrospective review of a trauma registry database over a 2-year period. Patients were included in the study if they were older than 15 years of age, had standardized axial bone-window CT imaging at C7, and had no evidence of spinal trauma. For each lamina and pedicle, width (outer cortical and inner cancellous), maximal screw length, and optimal screw trajectory were measured, and the maximal screw length of the lateral mass were measured using m-view 5.4 software. Statistical analysis was performed using Student's t-test. Results : At C7, the maximal PS length was significantly greater than the ILS and LMS length (PS, $33.9{\pm}3.1$ mm; ILS, $30.8{\pm}3.1$ mm; LMS, $10.6{\pm}1.3$; p<0.01). When the outer cortical and inner cancellous width was compared between the pedicle and lamina, the mean pedicle outer cortical width at C7 was wider than the lamina by an average of 0.6 mm (pedicle, $6.8{\pm}1.2$ mm; lamina, $6.2{\pm}1.2$ mm; p<0.01). At C7, 95.8% of the laminae measured accepted a 4.0-mm screw with a 1.0 mm of clearance, compared with 99.2% of pedicle. Of the laminae measured, 99.2% accepted a 3.5-mm screw with a 1.0 mm clearance, compared with 100% of the pedicle. When the outer cortical and inner cancellous height was compared between pedicle and lamina, the mean lamina outer cortical height at C7 was wider than the pedicle by an average of 9.9 mm (lamina, $18.6{\pm}2.0$ mm; pedicle, $8.7{\pm}1.3$ mm; p<0.01). The ideal screw trajectory at C7 was also measured ($47.8{\pm}4.8^{\circ}$ for ILS and $35.1{\pm}8.1^{\circ}$ for PS). Conclusion : Although pedicle screw fixation is the most ideal instrumentation method for C7 fixation with respect to length and cortical diameter, anatomical aspect of C7 lamina is affordable to place screw. Therefore, the C7 intralaminar screw could be an alternative fixation technique with few anatomic limitations in the cases when C7 pedicle screw fixation is not favorable. However, anatomical variations in the length and width must be considered when placing an intralaminar or pedicle screw at C7.

Purpose : The diagnosis of the causes of residual pain after ankle fractures and the treatment is not simple. The authors analyzed the clinical results of the patients with residual pain after ankle fracture fur whom ankle arthroscopy was undertaken, for the purpose of evaluating the efficacy of arthroscopic diagnosis and treatment. Materials and Methods : From January 1997 to June 1998, ankle arthroscopy was done for the seventeen patients suffering from residual ankle pain and limitation of motion after ankle fracture. Their symptoms were not improved despite conservative treatment. There were sixteen men and one woman, and their mean age was 37.4 years. Result : Radiological examination revealed loose bodies in two patients, and osteophytes at the anterior rim of the tibia in fourteen patients. By the classification of osteoarthritic change, three ankles were assigned to grade 0, eight to grade I, six to grade II, and none to grade III. On arthroscopic examination, soft tissue impingement was found In thirteen cases, loose bodies in five cases, and osteochondral lesions in four cases. For arthroscopic treatments, removal of soft tissue, abrasion of osteophytes, cartilage shaving and removal of loose bodies were done. Clinical results were evaluated using Evanski and Waugh score. Preoperative overall score of 58.7 points jumped to 74.6 points after the operation, and in fourteen patients$(82\%)$ the symptoms were improved. Conclusion : Ankle arthroscopy is considered to be a very useful diagnostic and treatment method fer the patients with residual complaints after ankle fracture.

Objectives: The objective of this study was to investigate the relationship between coronary artery calcification and risk factors of cardiovascular disease with multidetector computed tomography. Methods: Data were collected from 5,899 males between 30 and 59 years old by interview, survey, physical examination, blood test, and multidetector computed tomography in the university hospital from January 2010 to December 2011. We confirmed the coronary artery calcium scores of subjects by multidetector computed tomography and identified risk factors of cardiovascular disorders. We investigated the relationship between coronary artery calcification and risk factors of cardiovascular disorders. Results: Mean calcium score of the coronary arteries in 5,899 participants was 8.20, and 773 participants (13.1%) exhibited coronary artery calcification. The presence of coronary artery calcification was correlated to risk factors of cardiovascular disease (age, blood pressure, triglyceride, HDL cholesterol, LDL cholesterol, glucose, Apolipoprotein A-1, Apolipoprotein B, body mass index, waist circumference) and risk assessment tools of cardiovascular disorders. Significant predicted factors of coronary artery calcification had different patterns in each age group (30-39, 40-49, 50-59 years old). Conclusions: We confirmed the relationship between coronary artery calcification and either typical risk factors of cardiovascular disease or risk assessment tools of cardiovascular disease. In addition, we also observed that the pattern of these factors varied according to age. Therefore, age-related variation needs to be considered in management strategies to prevent cardiovascular disease.

Objectives: This study was to assess characteristics in acute stroke patients according to Sasangconstitution (SC). Methods : We assessed the type of SC of acute stroke patients in $2^{nd}$ Department of Internal Medicine at KyungHee University Oriental Hospital from October 2005 to September 2006. Each subject's SC type was confirmed when the result of QSCC II+ was in accordance with the opinion of the Sasangconstitutional medicine specialist. We investigated general characteristics, stroke type, blood test results, alcohol drinking, smoking and dietary preferences according to SC. Results: 108 subjects were included in the final analysis. This study showed that out of the total patients, the proportion of So-yang to Tae-eum to So-eum was equal to 5.5 to 3.5 to 1. Especially, men were higher proportion So-yang while women recorded a more significant ratio of Tae-eum. Also, the BMI, waist circumference, hip circumference, and WC/HC ratio recorded significantly high results. The result indicated that even though the Tae-eum let on the highest numerical value in the aspect of their past history and the final diagnosis, no significant difference was revealed according to SC. The ratio of cerebral infarction to cerebral hemorrhage was 9 to 1. SVO, LAA, SUE are the 3 types of cerebral infarction classified by TOAST; SVO ranked the highest while SUE ranked the lowest in all constitutions. The blood test result displayed that averages of both TL and the T-chol were the highest in Tae-eum while that of hematocrit in So-yangand that of HDL-chol in So-eum. However, there was no significant difference. There were no significant differences classified by gender or by SC in the aspect of the alcohol drinking and smoking history. The majority of So-yang and Tae-eum demonstrated a preference for meat while So-eum and So-yang displayed high preferences for sea food. Conclusions : With respect to these results. we could observe the general disposition of various characteristic distributions according to SC of acute stroke patients. For further research in this field. it seems necessary to construct fundamental databases for the prevention and treatment of stroke by increasing the number of patients observed and by analyzing delicate characteristics of each constitution type.

To correctly plant the value of sex to the juvenile, we cannot overemphasize the importance of the sexual education in schools. Therefore, the study for teachers' consciousness and view of sex is also necessary, because they are subjects of education and role-models of sex of their students. Especially, if teachers are over fifty in age, it is more important, because it is obvious, as they are in positions of managers and directors of education, that their view of sexual value and consciousness are influencing the aim of education and the course of education. Hereby this study was conducted to check their sexual consciousness, attitude, and condition and to prepare for the basic data needed for the development of a sexual education program suitable to them. The methods of the survey of this study are applied by modifying or supplementing those of precedented studies. They are used after analyzing reliance of items according to Cronbach's $\alpha$ figure calculating law, and modifying or supplementing items lower in reliance. The questionnaire survey was conducted among 1,000 randomly selected from teachers working in middle and high schools in Korea from June 14th in 2004 to June 30th. The survey analyzed 632 questionnaires suitable to it. The outcomes of the survey of this study are like the following: First, the objects of the survey consist of 64.6% men and 35.4% women. Among them, 41.1% are under fifty and the rest are over fifty. As for the periods of marriage, 15.5% are unmarried, 16.3% are under ten years, 18.0% are between ten and twenty, and 50.2% are over twenty. Second, with reagard to sex, 25.6% admit the necessity of a heterosexual friend. 32.0% say that they are conservative to sex. 54.1% are taught sexual education. 67.1% attribute sexual education to nursing teachers. Third, among those who answer that they enoughly know the concept of sex, seenig by age, 25.0% are under fifty and 58.1% are over fifty. Seening by the periods of marriage, 9.2% are unmarried, 28.2% are under ten, 49.1% are between ten and twenty, and 59.0% are over twenty. Among those who answer that they enoughly know the concepts of sexual harassment and sexual violence, seenig by age, in the turns by above-mentioned order, each 47.7% and 76.3%. Seening by the periods of marriage, each 9.2%, 28.2%, 49.1%, and 59.0%. Fourth, among those who answer that "teachers also need sexual education and sexual counsel," by age, each92.7% and 91.4%. By the periods of marriage, each 89.8%, 95.2%, 89.4%, and 92.4%. As a matter of course, we can infer the necessity of the sexual education and sexual counsel for teachers. Fifth, among those who answer that they are satisfied with their sexuality, by age, each 41.1% and 61.3%. By the period of marriage, each 4.1%, 63.1%, 64.1%, and 61.5%. As for the sexual desire like spiritual intercourse, physical intercourse containing sexuality, by age, each 71.9% and 93.5%. By the periods of marriage, each 54.0%, 81.5%, 90.3%, and 93.0%. The survey shows that those over fifty and having long marriage are feeling the stronger desire towards sexuality. Through the outcomes of this survey, a few suggestions are possible: First, it is necessary to check of the teachers' view of sexual value and to study deep about the sexual tendency of them in twenties, thirties, and forties. It is to make them teach their students on the firm basis, and also to develop suitable sexual education and counsel program.
