This study investigated the effect of maternal interactive styles, parenting stress, home environment stimulation and social support on poverty in early childhood. Participants consisted of 145 mothers and their children living in Seoul and Kyounggi Province. Data included videotaped observations of parent-child play and standardized measures of social support, parenting stress, home environment, and child development. Results of the t-test indicated significant differences among father's age and education, mother's age and education, and income over the variable of poverty. Regression analyses indicated that home environment stimulation was the strongest predictor of variance in children's development. Results from the regression analyse were supportive of the hypothesis that home environment moderates the impact of poverty on children's development.

In a competitive and globalized business environment, the need for the green products becomes stronger. To meet these trends, the environmental assessment besides delivery, cost and quality of products should be considered as an important factor in new product development phase. In this paper. a knowledge-based approximate life cycle assessment system (KALCAS) for the collaborative design environment is developed to assess the environmental impacts in context of product concept development. It aims at improving the environmental efficiency of the product using artificial neural networks consisting of high-level product attributes and LCA results. The overall framework of the collaborative environment including KALCAS is proposed. This architecture uses the CO environment to allow users on a wide variety of platforms to access the product data and other related information. It enables us to trade-off the evaluation results between the objectives of the product development including the approximate environmental assessment in the collaborative design environment.

Since the first sewage treatment plant had been in operation in 1976, the Korean water industry was in the logarithmic growing stage corresponded with the country's rapid economic expansion up to late 1990's. Unfortunately, however, the current industry status seems to require not only new paradigm for water environment but the development of new growth engine, since there are various warning signals for stalling growth from the field engineers to policy makers. Because of sharing of the awareness, the Korean government recently launched an ambitious development policy for water industry. This paper describes the new paradigm-shift in water environment in view point of the water as renewable resources. Based on the new paradigm, it has been suggested the prerequisite conditions to meet for the development of a new Korean water industry.

The major tributaries in Sapgyo-reservoir watershed at Chungcheongnam-do were monitored for flowrate and water quality in order to analyze the characteristics of watershed and to prepare for implementation of total maximum daily load (TMDL). According to the analytical results of flowrate and water quality monitoring data of sixteen tributaries, the tributaries with the value of flowrate over $0.5m^3/s$ were 62.5% among the monitored tributaries and the value of flowrate in the Cheonancheon, Namwoncheon, Shinyangcheon except Gokgyocheon, Muhancheon, Sapgyocheon was relatively greater than the other tributaries. However, 37.5% of the tributaries were exceeded the water quality standards of Sapgyocheon sub-basin ($BOD_5$ 5 mg/L and/or below) and the concentration of water pollutants regardless of water quality parameters in Cheonancheon, Maegokcheon, Oncheoncheon including Gokgyocheon located in Gokgyocheon catchment were relatively higher than the other tributaries. The tributaries for improving the water quality, according to stream grouping method based on the results of flowrate and water quality monitoring data, were selected. In the Sapgyo-reservoir watershed, the tributaries for improving water quality, which has a large flowrate and a high concentration of water pollutants, were selected at Cheonancheon, Gokgyocheon, Maegokcheon, Namwoncheon, Oncheoncheon. The various water quality improving plans for those tributaries, in accordance with the reduction of point source pollution by population and livestock, should be established and implemented.

Demand of new suburban residential development and a variety of new types for housing have intensified by urban Citizens overused of poor urban residential environment. Income growth and improvement of living standards for the quality of the living environment are increasing demands of creating a more comfortable living environment. Thus, according to changes in social conditions, the development of urban area while accommodating additional development pressure adequately, particularly residential development in order to promote the efficient development of suburban areas are planned for the rational development direction. This study suggests the following improvement measures by analyzing the characteristics of the Suburban Housing Complexes built recently. In order to create a more pleasant Suburban Housing Complexes First, the accessibility of the traffic conditions, education and public facilities is good Second, the construction plans reflected needs of the consumers should be made Third, necessary facilities for activation of the urban-rural exchanges must be equipped.

In this study, we propose the guideline with strategic model for new product development. To establish the guideline, 1) we classify several types of successful surveyed cases that achieved open innovation through applying crowdsourcing into new product development environment, 2) draw case maps using two or three axis with characteristics such as: step of product development process, crowdsourcing frequency, and product type of each case, 3) define the type of applying crowdsourcing into new product development environment based on case analysis results, and tabulate a crowdsourcing type based on the defined crowdsourcing type, 4) finally, suggest the guideline with multiple points of view which embrace type of crowd, community management, participation method, knowledge adoption method, and reward policy. Using the suggested guideline will help a company to design and establish open innovation in new business model related to product development area.

Through the harmony of natural and artificial systems a city is composed of, the ecology-oriented urban planning seeks for qualitative improvements of a city on which our life is based. To enhance the ecology-oriented urban planning, the followings are suggested by a comparative analysis of Korea with Germany regarding the development process, the instruments, and the establishment of indicators for the planning. Firstly, though our national land development plan is closely connected with B-plan, it has little to do with the natural environment. Moreover, the natural environment plan of the Ministry of Environment is almost impossible to carry out in terms of urban construction work. For this reason, the instrument for dealing with the development and environment plan systems together as well as the completion of the current plan system is needed for the ecologically acceptable urban development in the long term. Secondly, in order to realize what is mentioned above in the concrete it seems to be desirable for the system and the instrument to be devised at the extent of B-plan. The regulations of the plan should have strong legal binding force and practicality as well. The element of ecology-oriented urban planning are (1) degree of independence and appropriate density, (2) conservation of natural elements such as soil, water, animals and plants etc., (3) energy saving in land use, (4) activation of B-plan and inducement of active participation of residents. Thirdly, it will be useful to develop various kinds of indicators for the environment plan provided in advance so that the ecology-oriented urban developments may be under control. It also should be taken into consideration that the indicators are supposed to be comprehensive, representative, and practical enough to make the most of at the early stage of drawing up a plan. The kinds of indicators which can be used in the ecology-oriented urban development include (1) soil, (2) water, (3) vegetation and plants, (4) animals, (5) climate, and (6) transportation.

We analyzed with HPLC (High Performance Liquid Chromatography) analysis photosynthetic pigments and environmental factors, microscopic observations of the phytoplankton and zooplankton in the seawater every month from February 2009 to November 2010 in Haengam Bay. The level of dissolved inorganic nutrients was the highest between July and September, when freshwater influx was at its peak, whereas chlorophyll a levels were the highest in April and August. Also, phytoplankton pigment concentration increased when dissolved inorganic nutrients are carried into nearshore waters by rainfall runoff. Based on identification of phytoplankton and photosynthetic pigments results, diatoms were mainly dominant while dinoflagellate populations increased at July and August 2009, May 2010. The zooplankton communities are dominated in terms of Noctiluca scintillans. The contribution of Noctiluca scintillans in 2010 accounts for approximately 77.3% of the total zooplankton. Distribution patterns over time of zooplankton in the seasonal distribution of phytoplankton showed a different pattern.
