  • Desmoplastic small round cell tumor (DSRCT) is a rare malignant mesenchymal neoplasm. It mainly involves the abdominal or pelvic peritoneum of male adolescents. We report here the imprint cytologic features of a case of DSRCT occurring in the intraabdominal cavity of a 21-year-old man. A microscopic examination showed moderate cellularity. The tumor cells were singly arranged and arranged in clusters. The cells had round to oval nuclei with finely granular chromatin, inconspicuous nucleoli and scanty cytoplasm. Some tumor cells showed nuclear molding, and some cells had an epitheloid appearance with a large amount of lightly eosinophilic cytoplasm. A rosette-like pattern was present. Spindle-shaped, fibroblastic stromal cells were occasionally found. The tumor cells were immunoreactive for the markers cytokeratin (AE1/AE3), epithelial membrane antigen (EMA), desmin, vimentin and neuron specific enolase (NSE).

  • This paper describes the method of diagnosing the degradation by void defects of insulator inside in operation. Needle-shape void specimens, made from LDPE, were used to generate an electrical tree under ac voltage. The method uses a neural network system with input signal of AE patterns. AE pattern consists of the pulse count and average amplitude according to the phase angle. After the learning process was over, unknown emission patterns were put into the network. It was shown that the network discriminates the void deflects well. The effectiveness of the neural network system for partial discharge recognition was shown.

  • This study presents the cytologic features of peritoneal washings, with particular emphasis on the cytologic discrimination among serous, mucinous, and endometrioid adenocarcinoma of the ovary. We selected histologically confirmed 27 cases of peritoneal washing : 8 cases of serous cystadenocarcinomas, 5 cases of mucinous cystadenocarcinomas, and 14 cases of endometrioid adenocarcinomas. The most frequent cytologic pattern of three tumors was clusters. Ball pattern was found in serous cystadenocarcinoma(36%) and acinar pattern in endometrioid adenocarcinoma(36%). Mucinous adenocarcinoma showed mucoid background(100%) and endometrioid adenocarcinoma revealed inflammatory background(43%). The cytoplasmic vacuoles were noted in 80%, 13%, and 43% of mucinous, serous, and endometriold adenocarcinoma, respectively. The endometrioid adenocarcinoma showed prominent nucleoli(64%). In conclusion, the cytologic findings of mucinous cystadenocarcinoma were different from that of serous and endometrioid carcinomas, such as mucoid background, abundant cyytoplasm with vacuolated cytoplasm, and peripherally located cytoplasm. Although endometriold carcinoma showed acinar pattern and prominent nucleoli, the differential diagnosis between serous cystadenocarcinoma and endometrioid adenocarcinoma in peritoneal washing cytology was was always possible.

  • The objective of this study is to provide new direction on house design in consideration of the PC users' life pattern. This study found that PC use present conditions at home, demand for PC using space, and requirements for PC using area were analyzed. A survey was taken by 1108 residences, and the SPSS win.10 was applied for analysis. The survey was conducted to see the computer usage at home, demand and satisfaction for the PC using space. The results of this study were as follows; forty-seven percent of respondents said they used the PC in son's and daughter's room while 36.8% answered living room. It reflects that the whole family want to use the PC in the same area, or for their children's convenience. Users' consciousness was analyzed four factor, which were 'physical inconvenience:'satisfactions in PC position', 'inconvenience caused by narrowness', 'notion of privacy'. PC users' consciousness had significant differences in the satisfaction by PC users' characteristic and housing characteristic. It was to be classified that the PC use space into several pattern according to furniture arrangement, and channel pattern had the highest satisfaction among those pattern. Through this study, it is expected that new housing designs need to be made to reflect lese requirements into interior design and house plan for PC user's needs.

  • This study was attempted to provide the basic data concerning development of stress management program for hospital nurses, and to focused on the analysis of job stress and social support according to the types of behavior pattern. The subjects were 296 staff nurses at a general hospital in Seoul. Data were collected with self-reported questionnaires and analyzed by SPSS-PC+ 8.0 win for descriptive analysis and ANOVA analysis. The results of this study indicated that; 1) The perceived job stress was negatively correlated with social support and was positively correlated with TABP. 2) The score of the perceived job stress was higher in TABP nurses than TBBP. The TABP nurses usually perceived more support from peers than from supervisors These results showed that the staff nurses who supported from supervisor felt less stress, and the score of the perceived job stress was higher in TABP nurses than in TBBP. So the differences in social support and job stress according to the types of behavior pattern must be considered significantly in development of the staff nurses' stress management program. Also it was needed to develop the strategies that TABP nurses was effectively supported by the supervisor.

  • The purpose of this study was to investigate the antibiotic resistance pattern of E. coli and Salmonella spp. isolated from chicken feces. One hundred and forty-seven E. coli isolates showed resistance to tetracycline (95.2%), erythromycin (89.2%), ampicillin (70.1%), streptomycin (59.2%), cephalothin (56.5%), sulfamethoxazole/trimethoprim (53.7%), ciprofloxacin (57.1%), enrofloxacin (59.2%) and norfloxacin (57.1%). The multiple resistance was seen in 144 isolates (97.9%) and the rate of five, six and seven drugs resistance pattern were 20.4%, 18.4% and 16.3%, respectively. Also, the multiple resistance of E. coli to twelve drugs were seen in 1 isolates (0.7%). Fourteen Salmonella spp. showed resistance to ampicillin (50.0%), streptomycin (57.1%), erythromycin (64.3%) and tetracycline (57.1%) and the rate of two and three drugs resistance pattern were 4 isolates (28.6%), respectively. The prevalence of resistant organisms in Korea probably reflects lack of proper antibiotic policy resulting in prolonged and indiscriminate use of antimicrobial agents.

  • Through staggering advancements of technology and network as we know them as digital revolution, we have established a foundation of space in which we can express reality by eliminating the boundaries between expression, space, and movement. There are many ongoing approaches that aim to overcome the physically-fixed property of space where the mathematical-geometric notion of Voronoi Diagram is one of them. Although the repetitive increment based on self-organization during the process in which space is generated by the Voronoi Diagram forms a pattern and focuses on the formation, its pattern is not restricted to a single method of expression but evolves over self-control. The result of having analyzed spaces generated by the Voronoi Diagram in this study can be summarized as follows. First, the Voronoi computation method with self-organization property creates multiple levels, increments, and evolves through feedbacks among changes with the slightest order and in the absence of control. Secondly, after forming a pattern through such feedbacks comes the differentiation phase due to the presence of different properties. Thirdly, a space that has gone through the generation process retransforms through active interaction between changes and it obtains ambiguous boundaries and a repetitive pattern. This leads to an evolution of space through repetitive increments based on self-organization. Such flexible space creation is supported by various digital technologies where we believe a converging application of these studies, sciences, engineering concepts, and space design is and effective and new method in terms of space creation.

  • Purpose: The purpose of this study is to analyze the effect of the arm extension pattern of proprioceptive exercise program on the muscle activity of the opposite lower extremity. Methods: In this study, electromyogram MP150(Biopac system, USA) was applied to 20 healthy male subjects. Arm extension-adduction-internal rotation pattern was applied within initial, mid and end range in sling position and supine position for measurement. And the effect on the activity of rectus femoris and tibialis anterior muscle of the opposite lower extremity was compared and analyzed. Results: The results of this study were summarized as follows: First, there was a statistically significant difference of the activity of the tibialis anterior muscle within the Initial range in sling position and supine position(P<0.05). Second, there was a statistically significant difference of the activity of the tibialis anterior muscle within the end range in sling position and supine position(P<0.05). Conclusion: Rectus femoris and tibialis anterior muscles shows the higher activity in the supine position than in the sling position. Therefore, the supine position is more appropriate than the sling position to make irradiation on lower extremity muscle with the extension pattern.

  • This study was designed to testify the possibility and devise the method to manipulate the 3D body scan data to produce rounded-belt pattern adaptable to hip-type variation of women in their 20's. The results of this research were as follows : Firstly, based on drop-value distribution of hip and waist girth, 151 subjects were classified into three hip-types; Type 1 (15.23%) was 'cylinder type', showing lowest drop-value, Type 2 (69.54%) was 'average type' and Type3 (15.23%) was 'hourglass type' showing highest drop-value. Secondly, using CAD program, design lines for round shape belt were set on the surface of 3D scan data of representative subject of each type. And divided 3D surfaces were flattened onto the plane by the internal tools of CAD program. The measure, 'lifting value of round belt pattern', implying the level of curve ratio of pattern was higher in back than front. This result might be linked to the fact that the hip part is more protruded than the abdomen part. And the measures also showed highest values in Type 3(hourglass type) and lowest in Type 1(cylinder type), meaning that the pattern of Type 3 showed more rounded shape than that of Type 1. This finding implied that round belt for body type having high drop-value should be shaped more curved. Thirdly, difference ratios of outline length and area between 3D curves(body surface) and 2D plane(pattern) were 4.5% and 1.3%, respectively. This result demonstrated and solidified the feasibility of designing digital garment pattern from 3D body scan data.

  • This study was designed to generate briefs pattern for women in their twenties using 3D parametric body model. 151 women in their 20's were random sampled and measured using Martine's anthropometry. And one subject was chosen as the representative subject for 3D scanning. Parametric model was generated of using CATIA P3, Unigraphics NX4.0, Rapidform 2006. And the 3D surface of parametric body model was flattened onto the 2D plane. 3 downscale ratios(0%, 10%, 15%) were applied to generated pattern to figure out what downscale ratio was suitable to make briefs with stretch fabric. 4 kinds of experimental briefs were made with stretch fabrics(0%, 10%, 15% downscale) and worn on the dressform. Subjective evaluation on the appearance was done and the data was analyzed by ANOVA with post-hoc test. Briefs pattern was generated through the process of flattening the parametric surface and arranging the patches to make briefs pattern by dart manipulation. The different ration of outline and area between 3D surface and 2D pattern were 0.22% and 0.09% respectively. It showed that a parametric model could provide a desirable pattern with minute size error. The results of subjective evaluation on the appearance of 4 experimental briefs showed that stretch briefs with 15% downscale ratio was evaluated most highly in most items. Findings imply that it is feasible to apply 3D parametric model to generate patterns for various items considering various fabric properties.
