Objectives: The aim of this study was to analyze the related factors to dental caries incidence and increments of DMFT index in children`s permanent teeth. Methods: The subjects were 249 elementary school children at the baseline survey. At the four-year follow-up survey, number of subjects reduced to 141. In the first year, all subjects submitted the responses of questionnaire composed of demographic variables and oral health behaviors. They also received oral examination and tests of salivary excretion rate, salivary buffer capacity, Dentocult(R) SM and Dentocult(R) LB. In the first to fourth follow-up year, they received oral examinations. The relation of oral health-related factors with caries incidence and increments of DMFT and DMFS index was analyzed by chi-square test, ANOVA, logistic regression analysis and generalized linear model analysis using Poisson distribution. Results: At four-year follow-up survey, subjects whose Dentocult(R) SM was 2 or higher compared to subjects whose Dentocult(R) SM was 1 or less and subjects whose Dentocult(R) LB was 2 or higher compared to subjects whose Dentocult(R) LB was 1 or less had higher DMFT index increments. In DMFT index increments, the adjusted odds ratio of subjects whose dfs index of primary molars was 11 and more was 4.30 compared to subjects whose dfs index of primary molars was 0 adjusted for gender, daily frequency of toothbrushing and eating between meal, mother`s job, oral health education, salivary excretion, salivary buffer capacity and Dentocult(R) SM test. Conclusions: It was suggested that the caries incidence and increments of DMFT index in permanent teeth should be highly associated with salivary lactobacillus count and dfs index of primary molars.

목적: 한국에서 부인과 관련 암 치료를 받은 환자에서 하지부종의 유병률과 위험 인자의 확인하기 위하여 시행되었다. 연구 방법: 2003년 1월부터 2006년 12월까지 4년 동안 수술적 치료 및 비수술적 치료를 받은 242명의 부인과 암 환자의 의무기록과 면담을 후향적으로 분석하였다. 의무기록 혹은 면담에 의한 기록을 통해 하지부종이 있는 환자를 확인하였고, 그 후 통계학적인 특징, 다른 의학적 병력, 암의 유형과 병기, 림프절의 절제, 수술방법, 항암치료, 방사선치료, 호르몬치료와 혈액검사 결과를 확인하였다. 그리고 이 결과로부터 다중 다변량 회귀분석을 통하여 하지의 림프부종에 대한 위험 요인을 평가하였다. 결과: 242명의 환자 중 48명 (19.8%)에서 하지 림프부종이 있었다. 하지부종이 있는 환자들은 체질량 지수가 더 높았고, 방사선치료, 항암 치료의 병력이 있었으며, 림프절절제와 근치적 자궁절제술을 받았던 경우가 많았다. 다변량 분석을 통해 체질량 지수, 방사선 치료 병력과 림프절절제는 부인과 암치료 후 하지부종에 대한 독립적 위험 인자임을 보였다. 결론: 방사선 치료를 받았거나, 체질량 지수가 25 이상인 경우 그리고 림프절 절제를 시행한 환자는 부인과 암치료 후 하지부종이 발생할 가능성이 있다. 그래서 이들 환자들은 추적관찰 기간 동안 질병의 발생률과 예방법과 치료에 대하여 교육을 받아야 한다. Objective: To identify the prevalence and risk factors for lower limb lymphedema in the patients after gynecologic neoplasms treatment in Korea. Methods: We retrospectively reviewed the medical records and interviewed 242 gynecologic neoplasms patients who have managed surgically and medically over a 4 year period between January 2003 and December 2006. We identified the patients with lower limb lymphedema as described by the medical records or reported by the interviews. We obtained demographic characteristics, other medical history, cancer type, stage of cancer, lymph node dissection, chemotherapy, radiotherapy, hormone therapy and laboratory findings. Multiple logistic regression analysis was done to evaluate the risk factors for lower limb lymphedema. Results: Forty eight (19.8%) patients out of two hundred forty two had lower limb lymphedema. Those patients with lower limb lymphedema had a higher body mass index, radiotherapy history, chemotherapy history and lymph node dissection history, radical hysterectomy. Multivariate analysis revealed that body mass index, radiotherapy and lymph node dissection were independently risk factors for lower limb lymphedema after gynecologic neoplasms treatment. Conclusion: The patients who had radiotherapy, body mass index greater than 25 or lymph node dissection must be considered as potential candidates to have lower limb lymphedema in the patients after gynecologic neoplasms treatment. Therefore, these patients should be informed during the follow-up period about this morbidity, the preventive measures, and the treatments.
천비골 신경의 주행을 따라 발생한 족부의 지방종 거대증의 수술적 치료

지방종 거대증은 매우 드물게 발생하는 선천적 질환으로 섬유 지방세포의 비대를 동반한 중간엽 세포의 점진적인 과성장에 의해서 발생한다고 알려져 있고, 피하지방, 신경, 근육, 골막과 골수에 섬유-지방 조직의 침윤에 의한 거대지와 같은 비정상적 과성장을 특징으로 한다. 표재성 비골 신경을 침범한 경우는 국내 보고는 없으며 신경을 침범한 경우에는 신경 절제 등의 후유증으로 보존적 접근이 선호되나 저자들은 43세 남자 환자에서 천비골 신경을 침범하면서 족배부에 발생한 우측 지방종 거대증을 진단하고 수술적 치료 후 만족할 만한 결과를 얻었기에 문헌 고찰과 함께 증례 보고를 하고자 한다. Macrodystrophia lipomatosa is a congenital disease characterized by gradual proliferation in the mesenchymal cell, such as fibroadipose tissue. Pathologically, fatty tissue is deposited in the nerve sheath, periosteum, bone marrow, and subcutaneous tissue, contributing to the macrodactyly of the foot. To date, there has not been any report on macrodystrophia lipomatosa of the superficial peroneal nerve in the Korean orthopedic literature. Conservative approach, such as decompression or debulking surgery, is recommended due to neurogenic dysfunction. However, we report a 43-year-old male with macrodystrophia lipomatosa involving the superficial peroneal nerve of the right foot and ankle, who underwent a second toe ray amputation as well as soft tissue and nerve resection.

Zero energy solar house(ZeSH-II) is applied solar heating systems with geothermal heat pump as a auxiliary heating system, roof integrated PV module, it was analyzed and evaluated the integrated energy performance. According to the evaluation result, in the summer season energy consumption is recorded 2,299㎾(jun.~sep.), excluding the cooking load, but the ZeSH-II identified that the 79.21~90.9% of the energy self sufficiency could be achieved. The 70% of the energy self sufficiency rate of the total energy load, which is the second stage goal of this study. In summer, energy consumption pattern is not the same as winter of heat pump, lighting, and ceiling type fcu.

In this papers, we developed a daylight collecting system with a couple of parabolic dishes. The system has composed of a cylinderical collecting device in which two pairs of reflectors : the primary parabolic dish and the secondary spherical mirror have installed. and sun-tracking device in which a sun tracking sensor, control unit, and 2-axis driving mechanism have equiped. We have tested and revealed the system efficiency of the developed system.

In this paper, the performance of Hybrid Dimming control system for Daylighting system is evaluated by accredited tests. The system controls the balance of illuminance of daylight between daylight system and LED light system. It makes the normal illuminance of interior without the effects of weather by controlling the LED depending on the brightness of outside. For the tests, 6 diffusers(600x300mm) were installed in lighting area(36㎡) and normal operation of the system sensors were tested about the interference of sunlight. The results of the examinations were satisfied with the criteria of accredited tests. Further research is the verification of energy saving effect by comparing the Hybrid Dimming control system to current artificial light system.

Hypertrichosis cubiti, also named hairy elbows syndrome, circumscribed hypertrichosis in which a remarkable amount of long vellus hair is localized on the extensor surfaces of the upper extremities. We report a case of hairy elbows syndrome in a 12-year-old female patient, who was treated for short stature in pediatrics. She was referred to our department because of hypertrichosis of both elbows. Her height is 131cm, it is below 3 percentile of that of age. We could not find any physical abnormalities and other developmental disorders except short stature, But, Her intelligence is somewhat delayed comparative to that of age. She denied her family history about that. The literature on this subject is reviewed, and some clinical and etiopathogenic aspects are discussed.
