The study was to find out the current situation of supply and demand of apparel CAD systems in Korea. Also it was hoped to gather any valuable information about the current usage of apparel CAD systems for the development of the enhanced apparel CAD system. Three interviews were carried out for the study. The first interview with the importing agents was to find out the apparel CAD system's supplying situation. The second interview with the users of apparel CAD system was about the usage of the systems and related informations. The last interview was about the pattern making facilities, which was pointed out by the users to be the most inconvenient part of apparel CAD systems. The results of the survey were: 1. The supply and demand of apparel CAD systems is increasing. 2. The education, training, maintenance of the system should be improved by the supplier. 3. Apparel CAD systems are used for various production systems in the apparel industry. 4. 100% of the systems are utilized for pattern input and 89% of the systems are utilized for marker making. Only 15% of the systems are utilized in pattern making process, which 80% of the users realize to be computerized. 5. The most serious barrier to the better usage of the system is the communication with the system in foreign language. This barrier could be lifted when Korean apparel CAD system is developed.

Carcinosarcoma is a rare malignant, biphasic tumor comprised of carcinoma and sarcoma components. In the gastrointestinal tract, carcinosarcoma is most frequently seen in the esophagus and rarely in the stomach. We report a 51-year-old female patient with 2-month-history of epigastric pain and dyspepsia. Endoscopic finding revealed a huge ulcerative lesion that infiltrated from the antrum to the mid-body. An endoscopically taken biopsy revealed poorly differentiated malignant round cell neoplasm. After the palliative subtotal gastrectomy, immunohistochemical studies showed two positive reactions for the epithelial marker and mesenchymal marker. Based on the above findings, the patient was diagnosed with gastric carcinosarcoma. The immunohistochemical analysis is a critical method in making an accurate diagnosis of carcinosarcoma.

Thermal stress due to extreme changes in the thermal environment is a critical issue in cattle production. Many previous findings have shown a decrease in feed intake, milk yield, growth rate, and reproductive efficiency of cattle when subjected to thermal stress. Therefore, selecting thermo-tolerant animals is the primary goal of the efficiency of breeding programs to reduce those adverse impacts. The recent advances in molecular genetics have provided significant breeding advantages that allow the identification of molecular markers in both beef and dairy cattle breeding, including marker-assisted selection (MAS) as a tool in selecting superior thermo-tolerant animals. Single-nucleotide polymorphisms (SNPs), which can be detected by DNA sequencing, are desirable DNA markers for MAS due to their abundance in the genome's coding and non-coding regions. Many SNPs in some genes (e.g., HSP70, HSP90, HSF1, EIF2AK4, HSBP1, HSPB8, HSPB7, MYO1A, and ATP1A1) in various breeds of cattle have been analyzed to play key roles in many cellular activities during thermal stress and protecting cells against stress, making them potential candidate genes for molecular markers of thermotolerance. This review highlights the associations of SNPs within these genes with thermotolerance traits (e.g., blood biochemistry and physiological responses) and suggests their potential use as MAS in thermotolerant cattle breeding.

Objectives : Paeng-hwal is described as an insect herbal medicine used for digestive diseases in the Dong-ui-bo-gam. The origin of this herbal medicine is limited to several small crabs, such as Helice tridens. These crab species cohabitat in the same environment and share similar morphological characteristics, making it very difficult to distinguish and collect the individual species for use in dietary supplements or herbal medicines. This study was conducted to develop a genetic identification tool for discriminating among these closely related small crab species. Methods : CO1 DNA barcode regions of 15 samples from 6 species of small crabs were analyzed to obtain the individual sequences. To identify the correct species, comparative analyses were carried out using the database of the NCBI GenBank and the NIBR. SCAR primers were designed to develop simple and rapid assay methods using inter-species specific sequences. Optimal SCAR assay conditions were established through gradient PCR, and the limit of detection (LOD) was determined. Results : Six species of small crabs (Helicana tridens, Macrophthalmus abbreviatus, Helicana tientsinensis, Helicana wuana, Chiromantes dehaani, and Hemigrapsus penicillatus), which are distributed as Paeng-hwal, were identified through CO1 sequences analysis. We also developed SCAR markers to distinguish between six small crabs at the species level. Furthermore, we established the optimal PCR assay methods and the LOD of each individual species. Conclusions : The rapid and simple SCAR-PCR assay methods were developed to identify the species and control the quality of herbal medicines for Paeng-hwal based on the genetic analyses of CO1 DNA barcodes.

Image-based motion capture technology is often used in making realistic computer animation. In this paper we try to implement image-based motion rendering by fixing a camera to a PC. Existing image-based rendering algorithms have disadvantages of high computational burden or low accuracy. The former disadvantage causes too long making-time of an animation. The latter disadvantage degrades reality in making realistic animation. To compensate for those disadvantages of the existing approaches, this paper presents an image-based motion rendering algorithm with low computational load and high estimation accuracy. In the proposed approach, an incremental motion rendering algorithm with low computational load is analyzed in the respect of optimal control theory and revised so that its estimation accuracy is enhanced. If we apply this proposed approach to optic motion capture systems, we can obtain additional advantages that motion capture can be performed without any markers, and with low cost in the respect of equipments and spaces.

Interrogative sentences are generally used to perform speech acts of directly asking a question or making a request, but they are also used to convey such speech acts indirectly. In the utterances, such indirect uses of interrogative sentences usually carry speaker's emotion with a negative attitude, which is close to an expression of anger. The identification of such negative emotion is known as a difficult problem that requires relevant information in syntax, semantics, discourse, pragmatics, and speech signals. In this paper, we argue that the interrogatives used for indirect speech acts could serve as a dominant marker for identifying the emotional attitudes, such as anger, as compared to other emotion-related markers, such as discourse markers, adverbial words, and syntactic markers. To support such an argument, we analyze the dialogues collected from the Korean soap operas, and examine individual or cooperative influences of the emotion-related markers on emotional realization. The user study shows that the interrogatives could be utilized as a promising device for emotion identification.

Ovarian cancer is one of the leading causes of cancer-related deaths in gynecological malignancies. Over 70% of ovarian cancer cases are high-grade serous ovarian cancers and have high death rates due to their resistance to chemotherapy. Despite advances in surgical and pharmaceutical therapies, overall survival rates are not good, and making an accurate prediction of the prognosis is not easy because of the highly heterogeneous nature of ovarian cancer. To improve the patient's prognosis through proper treatment, we present a prognostic prediction model by integrating high-dimensional RNA sequencing data with their clinical data through the following steps: gene filtration, pre-screening, gene marker selection, integrated study of selected gene markers and prediction model building. These steps of the prognostic prediction model can be applied to other types of cancer besides ovarian cancer.
