  • The physiology of the unicellular green alga Dunaliella salina in response to abiotic stress has been studied for several decades. Early D. salina research focused on its remarkable salinity tolerance and ability, upon exposure to various abiotic stresses, to accumulate high concentrations of $\beta$-carotene and other carotenoid pigments valued highly as nutraceuticals. The simple life cycle and growth requirements of D. salina make this organism one of the large-scale commercially exploited microalgae for natural carotenoids. Recent advances in genomics and proteomics now allow investigation of abiotic stress responses at the molecular level. Detailed knowledge of isoprenoid biosynthesis mechanisms and the development of molecular tools and techniques for D. salina will allow the improvement of physiological characteristics of algal strains and the use of transgenic algae in bioreactors. Here we review D. salina isoprenoid and carotenoid biosynthesis regulation, and also the biotechnological and genetic transformation procedures developed for this alga that set the stage for its future use as a production system.

  • The meaning of fengshui was another cultural ecological environment in the pre-modern in Korea. Village residents made interrelations with village natural environment by the medium of the geomantic landscape. The functions of cultural ecology through the village fengshui are as follows: the spatial location, the population inflow, the regulation of the community's production or construction or land-use, the adjustment of the environmental carrying capacity, the environmental management, the forming of the collective environmental perception and attitude. Village fengshui is a cultural adaptation strategy to the local environment for the village residents. Fengshui can be evaluated as a traditional cultural ecological way and knowledge system for keeping sustainable village environment in East Asia.

  • With drinking water standards becoming more rigorous and increasing demands for additional water quantities, while water resources are becoming more polluted, mathematical models became an important tool to improve water treatment processes performance in the water supply system. Water treatment processes models reflect the knowledge of the processes and they are useful tools for water treatment process optimization, design, operator training for decision making and fundamental research. Unfortunately, in the current practice of drinking-water production and distribution, water treatment processes modeling is not successfully applied. This article presents a review of some existing water treatment processes simulators and the experience of their application and indicating the main weak points of each process. Also, new approaches in the modeling of water treatment are presented and recommendations are given for the work in the future.

  • Life of building repeats removal and new construction continuously because it is limited like living things. But, because the physical standard is subjective and abstract, saying too much is not even though it had been influenced by policy decision of the government. To solve these problem clear data about superannuation degree of building after construction accordingly decision relationship necessity continuously rise. To above background, this study on the Constructing Database Based and Improvement of Old Building using GIS in Busan. The results are as following. First, presented necessity of knowledge information gap mitigation. Second, present Busan's ordinance detailed Contents of old-badness building and production-consequences.

  • This paper describes acoustic phonetic parameters for detecting nasal place in a knowledge-based speech recognition system. Initial acoustic phonetic parameters are selected by studying nasal production mechanisms which are radiation of the sound through the nasal cavity. Nasals are produced with differing articulatory configuration which can be classified by measuring acoustic phonetic parameters such as band energy ratio, band energy differences, formants and formant differences. These acoustic phonetic parameters were tested in a classification experiment among labial nasal, alveolar nasal and velar nasal. An overall classification rate of 57.5% is obtained using the proposed acoustic phonetic parameters on the TIMIT database.

  • Can examine cause that the construction industry is faced in crisis of skill exhaustion in two sides. One is the tribe of actuality production manpower by entry evasion and graying of young man class specially new manpower to the tribe of skill manpower. Another is qualitative decline of skill manpower. Generally, problem of the systematic knowledge tribe and the picking up tribe about new technology etc, exists because learn skill for shoulder beyond in spot. In cutting phenomenon of skill that is depended on personal relationships availability with skilled worker in hereafter, problem that worker who is old or enter through rain skilled worker does not learn all life skill is detected. These problems institute entry of young man class and necessity of systematic vocational education training specially new human strength strongly. This study does presentation of way to promote construction industry entry of young man class and improvement way of vocational education training system that can do to train these by function manpower by purpose.

So couple of soldiers are think as the corresponds to college, or some knowledge layer from the operating management discarding period, lifetime value. But, now a day changed of the military life, it is when the individual soldiers can have some self-development and the lifelong education in terms of a period, and can changeing the footsteps of the new life that the function as a 'bridge' to activate production of barracks life. So that it can be supported themselves need to strive for human resource development.

  • The essential purpose of this study is to propose strategies for developing micro-, small-, and medium-sized enterprises (MSMEs) to realize sustainable competitive advantage by applying the SWOT analysis method. Thus, the main problems investigated in this study are: a) around 60-70% of MSMEs in Kulonprogo regency do not yet have access or financing from banks; b) lack of knowledge of production technology; c) in general, MSMEs business actors are still incorporated legal entities; d) MSMEs do not have a good financial administration and management system; e) coordination between MSMEs stakeholders has not been integrated; f) limited facilities and infrastructure of MSMEs, primarily related to technological tools; and g) limited access to raw materials so that MSMEs often get low-quality raw materials. This study employed a survey method with questionnaires and interviews. By using the Slovin tools sampling technique, the number of samples was 39 MSMEs in Kulonprogo Regency, Yogyakarta, Indonesia. The results of this study confirmed that the Kulonprogo MSMEs should pay attention to seven aspects of business management to achieve sustainable competitive advantage. The seven aspects are: 1) business strategy; 2) human resources; 3) information technology; 4) products; 5) promotion; 6) cooperation; and 7) corporate social responsibility (CSR).
