The skin is an uncommon site of distant metastasis from any internal malignancy, and the incidence of metastatic skin lesions as the first symptom of disease is only 0.8% in patients with all systemic malignancies. Furthermore, cutaneous metastasis from adenocarcinoma of the stomach has been found to be extremely rare. A 35-year-old female patient was admitted due to multiple cutaneous nodules in her chest, abdomen, and back. A gastroendoscopic examination and biopsy was made according to the results of skin pathologic findings. Stomach and skin biopsy results revealed a signet ring cell type of adenocarcinoma. A case of gastric adenocarcinoma in which metastatic skin nodules appeared as the first sign of disease, is here in reported with a review of related literature.

大邱-倭館 以北의 霞山洞層에 나타나는 赤色層 分布에 關하여

梁承榮 경북대학교 교육대학원 1972 논문집 Vol.3 No.-

This study deals with the distribution of Reddish beds of Hasandong Formation in the northern part of Daegu-Waegwan area. The numbers of Reddish beds are counted more than 100 at northern most part of the study area while only 10 at southern area of the middle part. Near the Mt. Palgong, Reddish beds are disappeared, but they appear again at south-east of Waegwan area. It seems that the Reddish beds cannot be interpreted as an indicator of the paleoclimate such as subtropical savanna. The geological boundaries, which were drawn according to intercalation of the Reddish beds,are never related to isochronous horizon. It seems that the disappearance of Reddish beds near the Mt.Palgong is partly due to the result of the intrusion of granite by which this area was affected thermal metamorphism. According to Rock Color Chart (published by G.S.A. 1963), the colors of 60 samples of Reddish beds are generally confined in 3 colors; grayish red(5R 4/2), grayish red (10R 4/2) and moderate red(5R 5/4). The microscopic examination shows that the most sandstones associated with the Reddish beds are classified as arkose according to Dapples' scheme(1953).

梁承榮,李倫鐘 慶北大學校 師範大學 1972 敎育硏究誌 Vol.14 No.-

The Seokgok Mine area, which is located in Dong-myun, Jungseon-gun, Kangwon-do, is composed of Pungchon limestone formation, Hwajeol formation, Dongjeom quartzite formation, Dumudong formation and Magdong limestone formation in ascending order, which are included in the so-called Great limestone Series, Cambro-Ordovician in age. The ore deposit is developed partially along the fracture in the Pungchon limestone formation. And its origin is considered as a filling replaced type. The shape of the ore body is very irregular and in which remains the non-replaced limestone relicts. Ore minerals are mainly galena, sphalerite, pyrite and chalcopyrite, which are associated with small amount of other sulfide minerals.

This paper presents experimental and analytical studies of ultimate strength of [30_2/-30_2/90]_s carbon/epoxy laminates with free-edge delamination under uniaxial tension. We performed tensile test for laminates with Telflon inserted on interfaces to simulate initial free-edge delamination. The experiment reveals that extensional stiffness of the laminate decreases by the initiation of the delamination, and that strength of the laminate without delamination is smaller than that of the laminated with delamination. Generalized quasi-three dimentional finite element analysis, which employs energy release rate and maximum stress criteria, predicts the ultimate strength of the laminates with sufficient accuracy.

본 연구는 농촌지역 정신과 환자들의 의료서비스 이용 형태를 알아보고자 하여 행하여졌다. 경기도 연천군 주민중 1993년 1년간 지역 의료보험과 의료보호자료에서 정신과적 진단을 받은 사람들 1295명 중 209명을 대상으로 하였다. 연구자들이 제작한 반구조화된 면담도구를 사용하여 13명의 훈련된 면담자에 의해 증상을 처음 느낀 후 이용한 의료서비스를 차례대로 조사하였다. 결과는 다음과 같다. 정신증적 장애 환자들은 정신과 치료만을 받은 경우가 28.8%이며 처음 방문한 의료서비스는 정신과 45%, 일반의 28%, 약국 6%, 한방치료 5%, 요양원 6%, 기타 10%였다. 비정신증적 장애 환자들은 정신과를 한번이라도 이용한 경우는 32.1%였고 처음 방문한 의료서비스는 정신과 15%, 일반의59%,약국 17%, 한방치료8%, 기타1%였다. 진단에 따라서는, 정신분열병의 경우 64.5%가 처음에 정신과를 방문하였고 정동형 정신병의 경우는 20.8%에 불과했고 64.1%가 일반이나 약국을 처음에 방문하였다. 신경증적 장애(ICD-9 300)는 40.0%가 일반의만을 방문했다. 이상의 결과로 정신분열병 환자들은 대다수가 정신과 치료를 받는 것으로 나타났으나 정동형 정신병과 신경증적 장애는 다수가 일반의를 이용하는 것으로 나타났다. 지역사회 정신보건에서 일반의의 역할이 매우 중요하며 일반의에 대한 정신과 교육이 절실하고, 보다 전문적인 치료환경과 기술을 요하는 경우에는 정신과와의 연계 체계의 필요성도 요구된다. The purpose of this study was to investigate the pathways of health care seeking by the psychiatric patients at a well - defined rural area in Korea. Among 1,295 patients diagnosed to have mental disorders by ICD-9 in a year, all the psychotic patients(184 in number) and randomly selected 15% of nonpsychotic patients(162 in number) were selected as subjects of this study. Thirteen well - trained interviewers collected the data using semi-structurd inter-view instrument developed by the authors. Two hundred nine patients(60.4%) fully responded to the interviews. As for psychotic patients, 28.8% used only psychiatric services, and the first visits for help were psychiatrists, general practitioners, pharmacists, asylums and oriental herb medicine in the order of decreasing frequency. Only 32.1% of nonpsychotic patients used mental health specialties during the course of their illness, and their most common first visits for care were general practitioners(59%) followed by pharmacists(17%) and psychiatrists(15%). Majority(64%) of schizophrenic patient visited psychiatrist first, while 64.1% of affective psychosis patients visited general practitioners and pharmacists first. The forty percent of neurotic patients(ICD-9 300) visited general practitioners only for their health care.

In this paper, A down converter to convert RF signal into IF signal is designed at the WLL base-station. It consists of low noise amplifier module and down mixer module. The low noise amplifier module is composed of three-stage and a feedback circuit is added in the first-stage low noise amplifier in order to obtain unconditional stability and good flatness. The configuration of the down mixer module is a single-ended type gate mixer. For the good isolation characteristic of each port, a bandpass filter and a lowpass filter are inserted in the input and output port. To design the down converter without the IF power amplifier, it is important to maximize conversion gain. So the down converter of this paper is designed for the purpose of obtaining a high conversion gain. From the results, the IF output power is -12.68dBm when the LO and the RF power level are 7dBm and -80dBm, respectively. Also when the LO power level is 7dBm, P1dB is -0.19dBm, and the RF input power range shows 70dB on wide operating range.

In this paper, the T-junction branch network of the orthomode transducer is analyzed. The T-junction blanch network consists of the cylindrical common waveguide and the rectangular sub-waveguide. Using the vector potential of each region, the hybrid mode is considered. Based on the derived electromagnetic components, scattering parameters of the T-junction branch network are calculated. The cylindrical waveguide size and the rectangular waveguide size are WR62 and WC55. In order to analyze the discontinuity of the T-junction branch network, high order mode of the branch region is considered the 15th. From the results, the transmission coefficient. S31 and S21 show -3dB, the reflection coefficient, S11 and S33 are -10dB, -8dB in the range of 13.3GMz∼16GHz.

Laser welding techniques have been characterised for various materials. In this paper. the laser weldability of STS304 stainless steel and Inconel 600 at dissimilar metal welds using a continuous wave Nd:YAG laser are experimentally investigated. Inconel 600 is being used in a steam generator tubing of pressurized water reactor(PWR) exposed to some corrosion. Stress corrosion cracking can occur on this material. An experimental study was conducted to determine effects of welding parameters, on eliminating or reducing the extent welding zone formation at dissimilar metal welds and to optimize those parameters that have the most influence parameters such as focus length, power, beam speed, shielding gas, and wave length of laser were tested.
