Most common metastatic tumors of the thyroid gland are squamous cell carcinoma of head and neck region, adenocarcinoma of breast and lung, malignant melanoma, and renal cell carcinoma of kidney in order of frequency. Metastasis from gastrointestinal tract to the thyroid gland rarely occurs. We experienced a case of fine needle aspiraton cytology of metastatic adenocarcinoma of both thyroid glands from the colon. Cytologic smears showed picket-fence like arrangement of nuclei of carcinoma cells and syncytial type of tissue fragments with acinar pattern on necrotic or mucoid background.

광역도시지역의 정부형태는 전통적으로 개혁이론과 공공선택론간의 대화에 의해 형성되어왔다. 현대 행정학의 이론적 바탕들 중의 하나로서 이러한 대화는 최근에 별다른 진전을 보지 못하고 있다. 본 논문은 이러한 지루한 이론적 대치상황을 타개하기 위하여 하나의 이슈를 제시하려고 한다. 그것은 이론적 대치상황 속에 존재하는 이론융합의 문제를 재규정함으로써 새로운 시작을 모색하는 것이다. 이것은 다중심 조직형태에 대한 우리의 논의를 촉발시키는 역할도 할 수 있을 것으로 기대된다.

패턴을 활용한 디자인의 방법들은 다양한 디자인 분야에서 활용이 되고 있다. 효용성이나 결과 또한 많은 발전을 하여 디자인에 있어서는 패턴이 없어서는 안 될 중요한 부분을 차지하고 있다. 장신구 디자인에 패턴은 자주 활용되고 다양한 기법으로 사용한다. 그러나, 장신구 디자인에는 공예적인 제작기법의 특성상 시간적인 제약과 집중력의 과다 등으로 패턴을 이용하고 그 패턴을 반복하고 배열하는 방식 활용에 많은 제약이 따른다. 그러므로, 본 연구에서는 장신구를 디자인에 있어서 전통적인 공예방식을 같이 겸비하며, 패턴의 응용과 반복, 그리고 패턴의 배열을 컴퓨터 프로그램으로 디자인하여 장신구 제작에 활용하고자 한다.

This study aims to identify the usage behavior of An-bang space in apartment dwellers through the perception, the residential life style and the use of furniture. The data is collected from interviewing housewives through questionnaire designed for this study. The 210 date were analyzed by using Frequencies, Mean, Factor analysis, ${\chi}^2-test$, t-test, one-way ANOVA and scheffe-test. The main results of the study are as follows: (1) It is called An-bang' or 'large room' rather than 'master's bedroom' although it is recognized as exclusively couple-oriented space. And are founded to be different designation and perception on An-bang space. (2) The residential life style in An-bang is classified as family-centered gathered, rest entertainment, make-up fitting and hobby. And it has significant differences among dwellers according to their personal characteristics. (3) The furniture style and arrangement pattern are mostly modern ones and 'ㄷ' type.

In order to rapidly catch up urban region’s detailed land-use or land-cover information; this research used the post-classification algorithm (Spatial Reclassification Kernel: SPARK) to create a land-use map of Taichung City. We discussed the urban land-use classification model with the IKONOS images. The conclusions may be distinguished as follows:(a) Using the Maximum-Likelihood algorithm to classify seven broad land-cover categories. The overall accuracy in this stage achieves 92.72% and Kappa coefficient will be obtained 0.91; and (b) Using the SPARK method to classify images for detect the land-use, the overall accuracy achieves higher 89.64% and Kappa coefficient will be 0.86. To conclude, the research process in this study can fully and carefully describe local land-use pattern and assist the demand of land management and resources planning reference.

Difficulties in developing process of Liquid Crystal Display(LCD) products such as frequent design modifications, various design requirements, and short-term development period bring on the need of integrated design approach that is efficient and easy to handle. Back Light Unit(BLU) of the LCD, which drastically affects the optical performance of LCD products, is divided into in-coupling part and out-coupling part. Serration of the in-coupling part flattens the light received from point light sources and dot pattern of the out-coupling part regularizes the light sent to screen. Therefore, the optical performance of a LCD product is largely influenced by the shape of serration and the arrangement of dot pattern. In this research, a new design approach which enables to improve the optical performance of LCD products and overcome the prementioned difficulties in developing process of LCD products is proposed. The shape of serration is parameterized to 3 parameters and out-coupling part is partitioned into 10 partitions to apply the optimization technique to this problem. 3 parameters for the shape of serration and densities of 10 partitions are used as design variables in the design optimization. Optical simulation tool named SPEOS is used to evaluate the optical performance of the LCD product. Since the optical simulation uses the random ray tracing technique, numerical noise may possibly be included in the simulation process. To solve the problem caused by numerical noise, the PQRSM which can stably find the solution of the noise problem is used in this research.

The water droplet motion in an air flow microchannel with pores through which water emerges is studied numerically by solving the equations governing the conservation of mass and momentum. The gas-liquid interface is tracked by a level set method which is based on a sharp-interface representation for accurately imposing the matching conditions at the interface and is modified to implement the contact angle conditions on the wall and pores. The numerical results show that the droplet growth and detachment pattern depend significantly on the contact angle and inlet air velocity. Also, the dynamic interaction between the droplets growing on multiple pores is investigated. The pore arrangement subject to droplet merging is found to be not effective for water removal.

A tooth solely can not be an exclusive factor to attain our goal, esthetics. Other consideration, such a proportion of individual tooth, harmonized arrangement of the dentition and surrounding tissues including gingiva, lip and face should be taken into account. Esthetic gingival pattern and incisal level in the anterior area are the very important factors for esthetic restoration of the smile. We often propose adequate periodontal and prosthodontic approaches in order to improve the esthetics of the anterior area. Here, I would like to share some cases which include soft tissue management for ovate pontic placement, osteoplasty, resin filling for severe cervical caries, and bleaching approach to discolored root caused by endodontic treatment, and so on.

An improved split-beam transducer for a 50 kHz fish-sizing echo sounder was developed. The main objective of this study was to minimize the side lobe level in the beam pattern and the distance between acoustic centers for adjacent transducer quadrants in the geometrical arrangement of array elements while maintaining a given number of transducer elements and beam width. To achieve these goals, a 32-element planar array transducer ($6{\times}6$ array with one element in each corner missing) was designed using the Dolph-Chebyshev shading function to suppress side lobes in the array beam pattern and fabricated by arranging the inter-element spacing to be substantially equal to half the wavelength using the transducer element of 0.4 times the wavelength in diameter. The performance characteristics of this split-beam transducer were evaluated in the experimental water tank of $5m{\times}5m{\times}6m$ (length${\times}$height${\times}$width). In this study, the design goal of the beam width and side lobe level for transmitting a beam pattern was initially set at $21^{\circ}$ and -30 dB, respectively. However, the measured beam width at 3 dB was $21^{\circ}$ in both directions with side lobe levels of -24.7 dB in the horizontal plane and -25.6 dB in the vertical plane. The averaged beam width at -3 dB of the receiving beam patterns for four receiving quadrants was $31.4^{\circ}$. The transmitting voltage response was 161.5 dB (re $1{\mu}Pa$/V at 1 m) at 50.23 kHz with a bandwidth of 2.16 kHz, and the averaged receiving sensitivity for four receiving quadrants was -178.13 dB (re 1 V/${\mu}Pa$) at 49.8 kHz with a bandwidth of 2.64 kHz.
