  • Production of biosurfactant can be substantially increased by the addition of precursors like vegetable oils, petroleum products, and other water-insoluble substances. Pseudomonas Ptm+ strain produces biosurfactant in the presence of hexachlorocyclohexane (HCH), which specifically emulsifies HCH, a recalcitrant organochlorine pesticide. Addition of previously produced crude biosurfactant by the same organism as a precursor instead of HCH increased production of biosurfactants with a decrease in the total fermentation time from 32 to 24 h. The main objective of this paper was to find alternatives for HCH as an inducer.

  • History documentaries in Korea have developed various forms of production techniques to overcome the limits of insufficient historical records and videos, and dramatic elements that make the viewers immersed. Through diverse production techniques, history documentaries can maximize the factuality, vividness, and informativeness, allowing the viewers to understand and share the historical events. This paper analyzed the "immersion and experience" techniques of the programs that have been the main turning points of the history documentary so far and produced and realized the virtual reality through utilizing "Uigwe", a 3D history documentary broadcasted on KBS which showed the possibility of applying the virtual reality technique as a new broadcasting contents format.

  • A bispecific antibody (BsAb) is an artificial protein containing two kinds of specific antigen binding sites. BsAb can connect target cells to functional cells or molecules, and thus stimulate a directed immune response. Last several decades a wide variety of bsAb formats and production technologies have been developed. BsAbs are constructed either chemically or biologically, exploiting techniques like cell fusion and recombinant DNA technologies. There are over 100 different formats of bsAb so far developed, but they could be classified into the two main categories such as Fc-based (with a Fc region) bsAbs and fragment-based (without a Fc region) bsAbs. BsAb has a broad application prospect in tumor immunotherapy and drug delivery. Here, we present a brief introduction to the structure of antibody, pharmacological mechanisms of antibodies and the trend in the production technologies of therapeutic antibodies. In addition, we address a review on the current status of various bsAb format development and their production technologies together with global situation in the clinical studies of bsAb.

  • Recently, the demand for the Floating, Production, Storage, and Offloading facility (FPSO) which has some economic and technical advantages, has increased in offshore oil production areas. FPSO vessel dose not have self-propulsion system, but has additional facilities for oil production and positioning system. Main noise sources such as gas turbines, compressors, and pumps, are located on top of the hull (Topside area). In general, the noise regulation for the offshore structure is severer than that of the cargo ship and acceptable noise limit of cabin is specified as 45 dB(A). This paper describes the noise characteristics and the countermeasures for FPSO Topside area through investigation of noise analysis and site measurement results. Proper countermeasures, considering the characteristics of sources and receiver spaces, were applied from the noise prediction and various measurement results. Finally, this ship was successfully delivered with excellent noise properties.

  • Data on 2,571 lactation records of Nili-Ravi buffaloes from four institutional herds and four field recording centers were analyzed under an animal model to see the effect of season definition on the error variance of the fitted model. Herd-year-season(HYS) was the main fixed effect along with permanent environment, breeding value and residuals as the random effects. All known relationships among the animals were considered. The error variance differed for various HYS combinations. It was minimum when then months were not grouped into seasons. The four or Five season scenarios were better than the two season scenarios. The average number of lactations represented in a HYS combination varied widely from 6 to 28. Very few subclasses for a given HYS combination warrants the use of fewer seasons for animal model evaluation of buffaloes.

  • This is a project presented to obtain Master of Fine Arts degree in Costume Production. The candidate has to present 20 costume illustrations and four full constructed costumes for selected actors. At the presentation, the candidate is given 45 minutes to present followed by questions asked by the committee and audiences and it was presented and exhibited in Brookline Arts Council. The thesis consists of two parts; research and analysis on the play, and the result of the design and production for the $play^{1)}$which consists of four fully built costumes-two in chosen fabrics and the other two in muslin with full closure worn on selected actors for each character. The period for the costume design is the Elizabethan period, the actual period the play Hamlet was written in England. The play Rosencrantz and Guildenstern are Dead is a play written in 1967 from a view of two small characters from Shakespeare's play Hamlet. So the costumes of Hamlet's characters are in full period, but the main two characters' costumes will have some of modern twists.

  • This paper deals with the attitude determination using GPS carrier phase. The main factors on attitude reliability are accuracy, error factors and the real-time ambiguity resolution speed. Firstly, these factors are reviewed. And then, the attitude reliability is improved by applying the averaging method. Finally, the attitude determination software is verified by the experiments. The accuracy of the proposed attitude determination method is 0.013$^{\circ}$ PE in live test. This result is more accurate than the existing INS equipment.

  • Rye stillage was adopted as a substrate for the production of yeast biomass by a thermotolerant yeast Candida rugosa isolated from East Africa. In the batch fermentation, the yield of biomass and crude protein reached 4.9-8.4g/l and 2.2-3.5g/l, respectively, the rate of COD reduction was about 20%. Over 90% amount of main components such as glycerol and lactic acid were assimilated, but protein assimilation reached only to 38-45% of the initial content. Crude protein content of the dry yeast biomass produced was 42-47% and sulfur-containing amino acid was revealed as limiting essential amino acid.

  • This case study surveyed management situations of environmentally friendly farming(EFF) producers' organization and their main activities. Farmers are aging as an average age of 55-year old and producing fruit-bearing vegetables. The EFF did not increase farmer's income, however, price and income was stabilized more than that of conventional farming because of contract farming. Farm household liabilities are caused by purchasing agricultural machinery, materials and so on. Farmers of EFF have been also cultivating conventional farming, but they don't plan much conversion intention of conventional farming into EFF owing to lack of differentiated and stable market for their EFF products. And they are guessing that EFF income will increase a little. For increasing of EFF income, they think that it is necessary to reduce production cost, produce high quality production, develop processing foods, enlarge contract farming and so on.

  • The essential oils from the roots of Codonopsis lanceolata and the cultivated callus were analysed and compared by gaschromatography-mass spectrometry. In the experimental study of cell culture, it appeared that 2,4-dichlorophenoxy acetic acid in the culture medium induced higher production of essential oils in the callus than indole acetic acid. The growth of callus was inhibited by illumination of the light. The production of essential oil in cultured cells was increased by the addition of biosynthetic precursors. The essential oils from the roots of Codonopsis lanceolata and the cultured callus showed different compositions. Tetradecanoic acid, 1,1,-dimethoxyl 4-methoxy phenol, 9,12-octadecanoic acid and hexadecanoic acid were identified as main components of the cultured callus oil.
