The genus Acanthamoeba can cause severe infections such as granulomatous amebic encephalitis and amebic keratitis in humans. However, little genomic information of Acanthamoeba has been reported. Here, we constructed Acanthamoeba expressed sequence tags (EST) database (Acanthamoeba EST DB) derived from our 4 kinds of Acanthamoeba cDNA library. The Acanthamoeba EST DB contains 3,897 EST generated from amebae under various conditions of long term in vitro culture, mouse brain passage, or encystation, and downloaded data of Acanthamoeba from National Center for Biotechnology Information (NCBI) and Taxonomically Broad EST Database (TBestDB). The almost reported eDNA/genomic sequences of Acanthamoeba provide stand alone BLAST system with nucleotide (BLAST NT) and amino acid (BLAST AA) sequence database. In BLAST results, each gene links for the significant information including sequence data, gene orthology annotations, relevant references, and a BlastX result. This is the first attempt for construction of Acanthamoeba database with genes expressed in diverse conditions. These data were integrated into a database (http://www. amoeba.or.kr).

Objectives: The purpose of this study is to review the research trends of infertile women with uterine myoma in Korean medicine and to recognize the efficacy of Korean medicine intervention. Methods: A search was conducted on November 18, 2022, using six databases, including Research Information Sharing Service (RISS), Oriental Medicine Advanced Searching Integrated System (OASIS), Cochrane Library Central, Pubmed, China National Knowledge Infrastructure (CNKI) and WangFang Med Online. We analyzed the studies using Korean medicine on women with uterine myoma preparing for pregnancy or complaining infertility. Results: Total 4 studies were selected and all of which were case reports. Among 6 cases, Korean medicine treatment including herbal medicine, acupuncture, electroacupuncture, moxibustion was used alone. Ikgibohyeol-tang-gami-bang, Gyejibokryeong-hwan, Saenghwa-tang-gami-bang were prescribed in 2 cases each. Angelicae Gigantis Radix and CV4 were most frequently used herb and acupoint. All subjects were successful in becoming pregnant. Conclusion: This review shows that Korean medicine treatment can be effective in infertile women with uterine myoma. However, the number of included studies is small, so the level of evidence needs to be raised through more clinical studies in the future.

When interacting with unknown environments, an autonomous agent needs to decide which action or action order can result in a good state and determine the transition probability based on the current state and the action taken. The traditional multiple sequential learning model requires predefined probability of the states' transition. This paper proposes a multiple sequential learning and prediction system with definition of autonomous states to enhance the automatic performance of existing AI algorithms. In sequence learning process, the sensed states are classified into several group by a set of proposed motivation filters to reduce the learning computation. In prediction process, the learning agent makes a decision based on the estimation of each state's cost to get a high payoff from the given environment. The proposed learning and prediction algorithms heightens the automatic planning of the autonomous agent for interacting with the dynamic unknown environment. This model was tested in a virtual library.

A robot system encompassing a remote control and monitoring through a virtual robot design is addressed and a tracking problem for a 2D (2 dimension) moving target by a robot vision is chosen as a case study. The virtual robot is developed, and it synchronizes with the real robot by compensating delay time. Two systems are displayed on a remote panel by communicating command and image data. The virtual robot utilizes an OpenGL library in Visual $C^{++}$ environment. Additionally, the remote monitoring and control between the real robot and the virtual robot are accomplished by employing an appropriate data compression in a network communication.

In this paper, a general fuzzy syntactic method for recognition of flaw patterns and for the measurement of flaw characteristic parameters for a non-destructive inspections signal, called eddy-current, is presented. Solutions are given to the subtasks of primitive pattern selection, signal to symbol transformation, pattern grammar formulation, and event-synchronous flaw pattern extraction based on the grammars. Fuzzy attribute grammars are used as the model for the pattern grammar because of their descriptive power in the face of uncertain constraints caused by nose or distortion in the signal waveform, due to their ability to handle syntactic as well as semantic information. This approach has been implemented and the performance of eh resultant system has been evaluated using a library of law patterns obtained from steam generator tubes in nuclear power plants by an eddy current-based non-destructive inspection method.

Human heavy chain (H-) and light chain (L-) ferritins were amplified from a human cDNA library. Each ferritin gene was inserted downstream of the T7 promoter of bacterial expression vectors, and two types of coexpression vectors were constructed. The expression levels of recombinant ferritins ranged about 26-36% of whole-cell protein. H-ferritin exhibited a lower expression ratio compared with L-ferritin, by a coexpression system. However, the coexpression of HL-ferritins was significantly increased above the expression ratio of H-ferritin by cultivation without IPTG induction overnight. Purified recombinant H-, L-, HL-, and LH-ferritins were shown to be homo- and heteropolymeric high molecular complexes and it was indicated that their assembled subunits would be able to work functionally in the cell. Thus, these results indicate an improvement in the expression strategy of H-ferritin for heteropolymeric production and studies of ferritin assembly in Escherichia coli.

The purpose of this study was to use the Kano model to compare and analyze the educational service quality attributes of domestic and foreign culinary arts schools. For this purpose, a questionnaire-based survey was completed by 312 students who were studying in domestic and foreign culinary schools. The results of the study indicated that 23 of the total 25 attributes were significantly different between domestic and foreign culinary arts school.; the "minium 4 hour-kitchen class" and "mandatory internship program" were classified into "indifferent quality" for domestic schools and a "must-be quality" for foreign schools; "well-organized internship guidebook", "kitchen class limited to 20 students", "introducing the latest food or restaurant trends", "library with the latest publications related to major", "objective instructor's evaluation", "detailed instructor's evaluation", "instructor's field experience", and "decent communication skills on the part of the instructor" attributes were classified into "attractive quality" for domestic schools and "must-be quality" for foreign schools; and "kitchen classes operated by block system", and "foreign instructors for each ethnic cuisine" attributes were classified into "indifferent" and "attractive quality" for both domestic and foreign schools, respectively. Also, according to the Better and Worse quotient designed by Timko, there were more attributes for domestic school than for foreign school that scored over 0.5 in the Better category and fewer attributes for domestic than the foreign scored over 0.5 in the Worse category. The results also indicate that, students in foreign schools receive an educational service of better quality than students in a domestic school. As a result, this research suggests significant implications to develop culinary educational services.

To speed up the conversion of rice straw into feeds in a low-temperature region, a start culture used for ensiling rice straw at low temperature was selected by continuous enrichment cultivation. During the selection, the microbial source for enrichment was rice straw and soil from two places in Northeast China. Lab-scale rice straw fermentation at $10^{\circ}C$ verified, compared with the commercial inoculant, that the selected start culture lowered the pH of the fermented rice straw more rapidly and produced more lactic acid. The results from denatured gradient gel eletrophoresis showed that the selected start culture could colonize into the rice straw fermentation system. To analyze the composition of the culture, a 16S rRNA gene clone library was constructed. Sequencing results showed that the culture mainly consisted of two bacterial species. One (A) belonged to Lactobacillus and another (B) belonged to Leuconostoc. To make clear the roles of composition microbes in the fermented system, quantitative PCR was used. For species A, the DNA mass increased continuously until sixteen days of the fermentation, which occupied 65%. For species B, the DNA mass amounted to 5.5% at six days of the fermentation, which was the maximum relative value during the fermentation. To the authors' best knowledge, this is the first report on ensiling rice straw with a selected starter at low temperature and investigation of the fermented characteristics.
