Laboratory works for embedded system courses are usually performed with hardware based experimental kits that equipped with an embedded board and software development tools. Hardware-based kits have demerits such as high initial setup cost, burdensome maintenance, inadaptability to industry evolution, and restricted educational outcomes. This paper proposes using virtual experimental environments to overcome the demerits of hardware-based kits and describes the design and implementation of a simulation-based virtual experimental kit. With ARM's ARMulator, we developed the kit by adding hardware IPs and user interface modules for peripherals. The developed kit is verified with an experimental program that uses all the augmented software modules. We also ported MicroC/OS-II on the virtual experimental kit for real-time OS experiments.

Many studies have reported that bleomycin, anti-cancer drug, induces pulmonary fibrosis as a side effect. However, few investigations have focused on the dose-response effects of bleomycin on pulmonary fibrosis. Therefore, in the present study, we investigated the effects of different doses of bleomycin in male mice. ICR mice were given 3 consecutive doses of bleomycin: 1, 2, or 4 mg/kg in bleomycin-treated (BT) groups and saline only in vehicle control (VC) groups. The animals were sacrificed at 7 and 24 days postinstillation. The severity of pulmonary fibrosis was evaluated according to inflammatory cell count and lactate dehydrogenase (LDH) activity in the broncho alveolar lavage fluid (BALF), and lung tissues were histologically evaluated after hematoxylin and eosin (H&E), and Masson's trichrome staining. BT groups exhibited changed cellular profiles in BAL fluid compared to the VC group, which had an increased number of total cells, neutrophils, and lymphocytes and a modest increase in the number of macrophages at 7 days post-bleomycin instillation. Moreover, BT groups showed a dose-dependent increase in LDH levels and inflammatory cell counts. However, at 24 days after treatment, collagen deposition, interstitial thickening, and granulomatous lesions were observed in the alveolar spaces in addition to a decrease in inflammatory cells. These results indicate that pulmonary fibrosis induced by 4 mg/kg bleomycin was more severe than that induced by 1 or 2 mg/kg. These data will be utilized in experimental animal models and as basic data to evaluate therapeutic candidates through non-invasive monitoring using the pulmonary fibrosis mouse model established in this study.

Commercial one-step rapid fecal occult blood (FOB) kit which was used as a screening test to detect traces of blood in stool samples was evaluated for the feasibility of the forensic identification of human blood. The sensitivity was determined and compared with the conventional Leucomalichite green (LMG) method. In addition, the specificity of the kit and the effects of various chemicals and environmental factors were examined. FOB kit was specific for human hemoglobin and more sensitive than LMG test (approximately 100 times). FOB kit showed positive band using at least 1,000,000-fold diluted human blood. The antigen was very stable regardless of storage temperature and boiling. The positive reaction was not affected by LMG and Luminol, the traditional tests for identification of bloodstain. As a results, FOB test kit could be effectively applied to identification of human blood at crime scene and crime laboratories.

Artemisia capillaris Thunb. and A. scoparia Waldst. & Kit. are classified by their root shape, leaf size and capitulum size. However, these characteristics are not nearly as useful when attempting to identify the two species owing to the continuous variation in them. Another important taxonomic characteristics is the habit, whether it is the subshrubs or perennial herbs of A. capillaris Thunb. or the annual or biennial herbs of A. scoparia Waldst. & Kit.. All observed specimens and living individuals in Korea are subshrubs or perennial herbs, and annual or biennial examples are not found. Therefore, it is considered that A. scoparia Waldst. & Kit. is not distributed in Korea.

The present study was conducted to develop a toxoplasma latex agglutination test antigen(Test-MT) and evaluate the toxoplasma latex agglutination(LA) test using a newly-made "Test-MT kit" by comparing with the Toxo-MT kit(Eiken chemical co, Tokyo). Also, the specifity and sensitivity test were made by comparing with IFA test and IgG-ELISA. Tachyzoite suspensions of Toxoplasma gondii(RH strain) were ultracentrifuged for 30min at $60,000{\times}g(4^{\circ}C)$ and the supernatant was used as a water-lysate antigen. Polystyrene latex particles of $1.0{\mu}m$ in diameter(Polyscience co) were used for the preparation of sensitized latex-antigen supension(Test-MT). The frequency distribution of LA titers in Test-MT showed two peaks at <1:32 and 1:128. The borderline titer for positive test in Test-MT was determined to be 1:64. But the frequency distribution of LA tites in Toxo-MT showed two peaks at <1:16 and 1:64. The positive borderline was determined to be 1:32. Agreement of reactions between Test-MT and Toxo-MT kit by LA test was shown 92.5% in bovine sera and 97.0% in swine sera, respectively. From the results obtained here it was determined that the sensitized latex-antigen, Test-MT kit, for the microtiter agglutination test prepared as same as by the procedure described in the previous paper(Suh and Lee, 1993) was useful as a highly specific, sensitive and stable immunotiteration reagent for serodiagnosis of toxoplasma infection in animal sera.

Aims: To study KIT (CD117) expression in thymic epithelial tumors in China, and investigate diagnostic and clinical significance. Material and Methods: Thymic epithelial tumors (TETs) from 102 patients (3 type A, 29 type AB, 5 type B1, 22 type B2, 29 typeB3 and 16 thymic carcinomas) were examined. Immunohistochemical staining with an antic-kit monoclonal antibody was performed on a tissue microarray. Relationships between KIT positive expression and the TET clinical characteristics (WHO histologic classification and Masaoka stage system) were analysed. Results: The KIT positive expression rate was significantly higher in thymic carcinoma (60%, 9/16) than in thymoma (8%, 7/86), a strong correlation being found with the WHO classification, but not the Masaoka tumor stage. The overall survival for patients with KIT positive lesions was significantly worse. Conclusions: KIT is a good molecule marker to differentially diagnose thymic carcinoma from thymoma, while also serving as a predictor of prognosis for TETs. Further research into KIT mutations in Chinese TETs should be conducted to assess the efficacy of targeted therapy.

Purpose: The purposes of this study were to assess the dentists' subjective satisfaction with the crestal approach sinus (CAS) kit, a device for maxillary sinus membrane elevation by the crestal approach using a special drilling system and hydraulic pressure, and to summarize the subjective satisfaction of dental implants placed after a sinus lift procedure with the CAS kit. Methods: Thirty dental clinicians who had experience with dental implant placement after a sinus lift procedure with the CAS kit from June 2010 to May 2012 were included in this study. The questionnaire for the evaluation of the dentists' subjective satisfaction with the CAS kit was sent to the respondents and returned. The questionnaire was composed of two main parts. The first part was related to the sinus membrane perforation rate. The second part was related to the dentists' subjective satisfaction with the CAS kit. Results: A total of 28 dentists answered the questionnaire. Among 924 implant cases, sinus membrane perforation occurred in 38 cases (4.1%). Among the 28 dentists, 26 dentists (92.9%) were satisfied or very satisfied with the CAS kit. In particular, 24 dentists (85.7%) reported that safety, cutting performance, and user-friendliness of the CAS drill were advantages of the CAS kit. However, 7 dentists (25%) did not routinely use the hydraulic lifter for sinus membrane elevation. Conclusions: From the survey, it was shown that the respondents were generally satisfied with the CAS kit and that the cutting performance and safety of the drill component were considered strengths of the CAS kit.

This study was conducted to investigate the optimal artificial insemination (AI) time with diagnostic kit at ovulation time. We already applied the patent about the protein in the cow heat mucose in external reproductive tract. And we would examine the accuracy for detection of cow heat by the kit produced with the protein. Evaluation of optimal heat detection was tried two time at 12 hrs and 24 hrs after the heat. And then, AI service also performed two times with no relation to the results of heat diagnosis by heat detection kit and pregnancy rates were checked with rectal palpation on $60^{th}$ day after AI. Heat diagnostic results by kit in natural heat after 12 hrs in Hanwoo cows were showed 31.3~75.0% on positive in first heat detection and 33.3~100.0% on positve in second heat detection. In the $1^{st}$ positive results were significant different (p<0.05), but $2^{nd}$ positive were not. The results of heat detection showed different result on regional influence and individual cow effects. The pregnancy rates of first trial of heat detection were showed 34.4~78.7% on positive and 21.3~68.8% on negative after the diagnosis by heat detection kit. And the pregnancy rates of next trial of heat detection were showed 33.3~85.7% on positive and 14.3~66.6% on negative after the heat diagnosis. Both positive results of first trial and next trial also were showed significant different (p<0.05), but negative results were not. In positive result, first trial of total pregnancy rates was higher than the next trial of pregnancy, but there showed opposite results on negative results. In conclusion, the optimal heat detection kit is suitable to ordinary Hanwoo cows and it suggested that we have to improve the kit's accuracy by detecting the materials like proteins related optimal AI time.
