Netherton's syndrome is an unusual disorder which consists of triad of ichtyosiform dermatosis, multiple defects of hair shaft and an atopic diathesis. The finding of bamboo hair is pathognomic in Netherton's syndrome and the ichthyosiform dermatosis may consist of either ichtyosis linearis circumflexa or congenital ichthyosiform erythroderma. Often, variability in the clinical features leads to a delay in diagnosis in many cases. We report a case of Netherton's syndrome diagnosed in the neonatal period. The patient presented with severe ichthyosis and confirmed microscopically distinctive bamboo hair.

A 54-year-old woman presented with an exophthalmos and a mass on her right eye, which proved to be recurred adenoid cystic carcinoma of the lacrimal gland. Orbital CT and MRI showed that tumor was located in the right orbit, but skin over right eye brow was also involved. There was no visualization of tumor extension into the intracranial compartment. The authors have performed an en bloc orbitectomy. Although en bloc orbitectomy is known to be useful in reducing recurrence, this case showed the tumor recurrence and even distant metastasis that occurred after total tumor removal via en bloc orbitectomy. As adenoid cystic carcinoma of lacrimal gland is known to have high rate of recurrence and metastasis, en bloc orbitectomy should be performed to reduce local advancement and distant metastasis. In case of distant metastasis, radiotherapy could be useful strategy in selected case.

Adenoid cystic carcinoma (ACC) of larynx is a rare disease, accounting for less than 1% of laryngeal malignancies, These tumors arise almost exclusively in the subglottic and supraglottic regions, while the proportion of glottic ACCs is small. We describe a case of a young man with a subglottis adenoid cystic carcinoma, The patient underwent laryngeal microscopic surgery and radiotherapy, Five years after radiotherapy, local recurrence and distant metastasis Clung and kidney) was detected and he underwent palliative chemotherapy and local treatment. He is still alive for seven years after the initial diagnosis. The treatment strategies for laryngeal ACC are still controversial due to the rarity of the condition. We suggest that multimodality approach may be helpful in deciding a treatment option, and thorough and consistent follow-up for recurrence is mandatory for these patients.

Adenoid cystic carcinoma is a malignant salivary gland tumor with typical histologic patterns. The majority of these tumors occurs in the minor salivary glands. especially mucosa of the hard palate. The authors experienced the patients, who complained the tumor-like soft tissue masses on the palatal and mouth floor area. After careful analysis of clinical, radiological and histopathological findings, we diagnosed them as adenoid cystic carcinomas in the minor salivary glands, and obtained results were as follows : 1. Main clinical symptoms were a slow growing soft tissue mass with normal intact mucosa on the palatal area, and soft tissue mass with mild pain on the mouth floor area. 2. In the radiographic exarnminations, soft tissue masses were observed with invasion to adjacent structures, and moderate defined, heterogeneous soft tissue mass with enhanced margin, respectively. 3. In the histopathologic exarnminations, dark-stained, small uniform basaloid cells in the hyaline or fibrous stroma were observed as solid and cribriform patterns, respectively.

Triangulation is a typical method to locate or identify the location, which requires inherently at least three pre-recognized reference points. In some cases, owing to out of reachability to communication facility the target node can not reachable always to three base stations. This paper presents a predictive method, which can estimate the location of the moving target node in real time even though the target could not get in touch with all three base stations. The method is based on the PID-controlled Moving Objects Spatio-Temporal Model Algorithm. This can predict the moving direction of the moving target, and then combine with the past target position information to judge accurately the location.

In this paper, thin films of PI were fabricated VDPM of dry processes which are easy to control the film's thickness and hard to pollute due to volatile solvents. From FT-lR, PAA thin films fabricated by VDP were changed to PI thin films by thermal curing. From SEM, AFM and Ellipsometer experimental, as the higher curing temperatures the films thickness decreases and reflectance increases. Therefore, Pl could be fabricated stable by increasing curing temperature. The relative permitivity and dissipation loss factor were 3.7 and 0.008. Also, the resistivity was about $1.05{\times}10^{15}{\Omega}cm$ at $30^{\circ}C$.

Various methods are available for determination of exposure time in intracavitary radiotherapy of the carcinoma of the uterine cervix. To determine the accuracy of dose calculation with isodose curve for TAO applicator, comparison with results calculated by computer for radiotherapy treatment Planning was done in 24 procedures done in 12 consecutive patients with the carcinoma of the uterine cervix from May to December, 1983. The results are as follows: 1. The average dose rate Per hour of Point A was 87.70 rad, being 89.91 rad ana 85.49 rad in left and right, respectively. 2. The average percentage of dose rate of point A calculated by isodose curve method over that by computer was $101.28\%$ and the difference was less than $5\%$ in 17 Procedures and over $10\%$ in only 3 procedures. 3. The average percentage in case of point B was $108.67\%$. In conclusion, in most cases the difference was less than 200 rad for point A and less than 100 rad for point B during 2 courses of intracavitary radiotherapy. And so the dose rate calculation with isodose curve for TAO applicator is comparatively accurate.

Adenoid cystic carcinoma is characterized by sloe growth, multiple recurrence, a long clinical course and late metastasis. It is less than 1% of all head and neck malignancy, but most prevalent malignancy in salivary gland origin. During 14 years(from 1982 to 1995), 24 patients were diagnosed as adenoid cystic carcinoma in oral and maxillfacial area, in department of Oral and Maxillofacial Surgery, Korea Cancer Center Hospital. We studied clinically about their age and sex distribution, primary site distribution, TNM staging, treatment modalities, overall survival rates, survival rates according to stages. The age range were from 15 years to 79 years, average age weas 51 years. 15 were men and 9 Were women. Maxilla and palate were the most prevalent primary site. The most cases were in stage III(37%) and stage IV(46%). The 3 year and 5 year overall survival rate were 65.0% and 58.5%. The 5 year survival rate of the stage III cases was 66.7%, and that of the stage IV cases was 38.4%.

3차원 자유곡면을 볼엔드밀을 사용하여 금형가공을 할 경우, 가공면에는 공구경로에 따른 흔적과 NC공작기계의 직선보간시 발생되는 가공오차에 의하여 공작물 상에 가공오차가 필연적으로 발생되게 된다. 따라서 공작기계상에 서 금형가공을 수행한 후에는 가공오차를 제거하고 금형의 표면을 매끄럽게 하기위하여 연마작업이 픽수적으로 요구 되고있다. 본 연구에서는 3차원 자유곡면으로 이루어진 금형의 연마가공에 로봇을 도입하고, 이를 위한 로봇 작업단의 경로 제어시비전문가라 할지라도 CAM시스템으로 부터 금형 가공용 NC공작기계의 공구경로데이타(Cutter Location Data)를 받으면 자유곡면을 모형화한 후 자유곡면의 법선벡터와 연마로봇 작업단의 위치벡터를 자동으로 생성하고, 그에 따른 로봇의 작업명령을 자동으로 생성할 수 있는 CAMPoli 오프라인 로봇 프로그래밍 시스템을 개발하였다. CAMPoli시스템은 마이크로소프트사의 WINDOWS/386 오퍼레이팅 시스템을 이용하여 IBM-PC/386 상에서 개발되었으며 그주요한 내용들은 다음과 같다. i) CAM시스템으로 부터 입력된 CL-데이타로부터 연마면에 대한 자유곡면을 생성하고, ii) 연마공정의 데이타베이스에 기초한 연마면수의 지정 및 변경을 수행하고, iii) 자유곡면 연마를 위한 로봇 작업단의 위치벡터와 법선벡터를 계산하고, iv) 기존의 로봇언어를 이용한 오프라인 소스프로그램(Source Program)을 생성 및 그래픽 시뮬레이션 하는 과정으로 구축되었다.
