In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

We have grown Zr based vitreloy alloy thin films by thermal deposition methode and ion beam sputtering method and compared them with Zr-Ti-Cu-Ni-Be bulk metallic glass bulk. Thermal analysis caused Zr-Ti-Cu-Ni-Be bulk metallic glass to recrystallize in the two region. The onset point temperature of the first region was 414.12℃ and the peak temperature was 410.02℃. The onset point temperature of the second region was 445.21℃ and the peak point temperature was 454.45℃. The X-ray diffraction measurement and thermal analysis as a function of temperature showed that the bulk metallic glass thin films recrystallize in the same temperature region. As a result, Zr based vitreloy alloy was the same as phase transition of bulk metallic glass bulk and bulk metallic glass thin film.

초고진공 상태에서 p형 Si(111)기판에 Ti을 증착한 후 고진공에서 열처리하여 Ti-실리사이드를 형성시켰으며, Ti-실리사이드의 상전이 및 형성운동학은 2 MeV⁴He? 이온 후방산란과 x-선 회절방법으로 규명하였다. 형성된 TiSi₂는 결정학적으로 C49(ZrSi₂)와 C54 구조의 두 종류로 확인되었다. C49 TiSi₂상은 열처리온도가 700℃이하의 저온에서 형성되었고, 700℃ 이상의 고온에서는 C54 TiSi₂상으로 나타났다. 본 연구에서 확인된 C54 TiSi₂전이온도(??)는 700℃ 였고, TiSi₂형성온도 영역내에서 TiSi₂ 층두께(χ)와 열처리시간(t)의 관계는 저온(700℃ 이하)일 경우 ??이고, 고온(750℃ 이상)에서는 χ=ct+d 의 관계식이 만족됨을 알 수 있었다. 이것은 700℃ 이하에서 TiSi₂ 형성기구가 Si 확산에 의해 제어되며, 750℃ 이상에서는 핵형성 제어에 의하여 계면반응하는 것으로 나타났다. Titanium silicides were prepared by depositing titanium film on p-type Si(111) followed by annealing in ultra high vacuum. The growth kinetics of Ti-silicide has been studied by using ion backscattering spectrometry and x-ray diffractometry. Two crystallographic structures of Ti-silicide were identified the (ZrSi₂)structure and C54. The C49 TiSi₂ phase was formed at low annealing temperature(<700℃),and it transformed to the C54 phase over 700℃. The relation between the thickness of TiSi₂ layer(χ) and the annealing time(t) was ?? when annealing temperature was under 700℃ and χ=ct+d when that was over 750℃. The former implied that the formation of TiSi₂ was controlled by diffusion and the latter by nucleation of at the Ti/Si(111) interface.

We report a case of twenty-nail dystrophy accompanied by alopecia universalis in a 45-year old woman. She had developed dystrophic nail changes on her all finger and toe nails for 26 years and alopecia universalis for 10 years. On examination, 20 nails were affectedwith opalescent, thickening, longitudinal ridging, and total hair loss were in scalp, eyebrow, axilla, and pubic area. Mycologic study of involved nails was performed, but negative results were obtained. Histologic findings of dystrophic nails revealed prominent hyperkeratosis, acanthosis, and mild infiltration of mononucler cells in the upper dermis. The histologic findings of scalp showed a few atrophic hair follicle, thining of epidermis, and slightly hyperkeratosis. All of these clinical and histologic findings were considered as twenty-nail dystrophy accompanied by alopecia universalis. She was treated with intralesional injection of triamcinolone acetonide and topical application of dinitrochlorobenzene, but no significant improvement was made. The further observation is being conducted.

Backgrounds and Objectives: Vascular dementia is a group of dementing disoders arising from various stroke syndrome. Among these. subcortical ischemic vascular dementia (SIVD) is regarded as a relatively distinct clinical entity. However, MRI patterns of SIVD are not homogenous. In some patients, lacunes are dominant, and in others, subcortical white matter changes are. This study was designed to compare risk factor profiles between SIVD with and without multiple lacunes. Methods: We divided 47 subjects (22 males, mean age. 68 years) recruited from VADAPET (Multicenter Trial For Evaluation Of The Changes In the PET Images Of Subcortical Vascular Dementia Patient) study into two groups one with more than 5 lacunes in deep gray matter (lacune group) and the other with 5 or less(non-lacune group) Clinical characteristics and laboratory findings of two groups were compared. Results: Nineteen of 47 patients (40%) belonged to the lacune group. The lacune and non-lacune groups d d not differ in the following variables: age, hypertension, diabetes mellitus, hyperlipidemia heart disease, history of stroke or TIA, history of trauma or major surgery, family history of hypertension stroke, or dementia, age at diagnosis of dementia, body mass index, white blood cell count, ESR, CRP, fibrinogen, hemoglobin A1C, total cholesterol. LDL cholesterol creatinine, proteinuria, glucosuria, and microhematuria. However, male sex, smoking alcohol. hemoglobin, and HDL cholesterol were possibly associated more with lacune group SIVD than with non-lacune group (p<0 1) Multivariate analyses revealed that smoking, hemoglobin, and HDL cholesterol were independent predictors of SIVD with multiple lacunes Conclusion: Our study suggests that SIVD with multiple lacunes may be significantly different in smoking habits hemoglobin, and HDL cholesterol from SIVD without multiple lacunes.

The goal of this paper is to predict accurately the two-tone third-order intercept point of N-cascaded power amplifiers with simplified two-port analyses and statistical viewpoint. The uncertainty obtained from unknown phase angles of the intermodulation distortion signals to the system designer is reduced using stochastic process, hence improving the accuracy of the solution. Based on the dc power dependance of intercept point of each stage, the new efficient method for improving the total intercept point is also suggested with only dc power and available power gain criteria. Experimental verification on specific amplifiers used for cellular mobile communication comparing predicted and measured intercept points for various gain conditions in presented.

Authors have studied retrospectively the facial nerve injury after TMJ surgery through the preauricular approach routine. The study material used was 4 patients of all 113 patients who were diagnosed as internal derangement and have been operated from March 1989 to February 1991 in Youngdong severance hospital, and were induced postoperatived facial nerve injury. The patient group who had the postoperative injured facial nerve was recognized degree of injury using the diagnostic method, Electromyography(EMG) and Nerve conduction test(NCT) which are used widely at present and was treated as conservative care and we identified the recovery time as the same method. The results as follows : 1. The meticulous care and precious surgical technique are needed in both operation and postoperation. During the TMJ surgery, the excessive retraction of the flap and frequent use of nerve stimulator and electric surgical knife should be avoided as possible and postoperative hematoma and swelling should be minimized. 2. The 4 patients were experienced with the postoperative facial nerve injury of all 133 patients who had been operated the TMJ surgery through the routine preauricular approach on our hospital. And the incidence of postoperative facial nerve injury happened was about 0.3% and its incidence was relatively low comparing with any other previous reports. 3. EMG and NCT were considered as useful methods which can diagnose the nerve injury objectively and identified the effect of treatment and recovery time. 4. The faical nerve-injured patients who were induced postoperatively after TMJ surgery, were diagnosed as second-degree nere injury through the EMG and NCT. And the patient group was treated well as conservative physical therapy for about 2 to 4 months.

This article is an abstract of the prize-winner master plan for Wolmee Park in Incheon, Korea. The main theme of the park is the revival of the Korean traditional garden style. The park provides a place for citizens to understand and experience Korean traditional garden styles by emphasizing Koreas traditional images and feelings. In addition, cultural traditions are harmonized with modern characteristics of the park. The plan includes restoring Wolmee-haenggung(a temporary palace used to be in Wolmee Island) to hold its traditional meaning as garden and plate of the Wolmee Island. Main design ideas are summarized below. First, the conceptual meaning of jeong-won(庭園, garden) is represented separately: jeong(庭) and won(園). Jeong(庭) is a man-made place and reappeared as tangible objects with traditional forms. In contrast, won(園) with the concept of wonrim(園林), the universal principle of Korean traditional garden style, which focuses on the harmony between human and nature, is symbolically represented as wolmeegugok(月尾九曲, nine beautiful landscapes along the river). Second, to deliver the meanings of the place, various historical and cultural elements of Wolmee Island are metaphorically added to the traditional garden frameworks. And third, the plan basically orients to preserve the ecologically healthy natural environment of Mt. Wolmee. The park will contribute for Incheon citizens as well as people nearby by providing healthy environment and various recreational activities.
