The purpose of this study was to investigate the effects of HACCP education on improvements of knowledge in school foodservice employees in Gyeonggi-do, particularly in Anyang, Ansan, Siheung and Hwasung City. A first and second questionnaire was answered both before and after HACCP education that was directed by a dietitian. The change in HACCP knowledge after education, as compared to before, was statistically significant(p<0.01). Specifically, the average score after education increased more than 30 points in CCP2 and CCP6, and more than 60 points in CCP3. Most of the school foodservice operations performed sanitary education once a month; however, they did not perform regular HACCP education. The fact that the level of sanitary knowledge was different after HACCP education than before suggests the possibility of improving the sanitary performance levels of foodservice employees through continual education.

The primary goal of the study was to provide some preliminary validity evidence for the Vocabulary Grade Levels Test (Busan Metropolitan City Office of Education, 2009), which is designed to measure the receptive vocabulary knowledge of learners in L2. For the purpose of the current study, 327 participants at the elementary school participated in the study and were asked to take two different vocabulary tests. Namely, a Vocabulary Size Test (Nation, 2001) and a Vocabulary Grade Levels Test. The data were analyzed using correlation in order to discover the relationship between these two types of tests. Following this, the Rasch analysis was conducted to examine the reliability and validity of the measurement in question. The data analysis showed that both grade separation reliability and item separation reliability were high, indicating that the Vocabulary Grade Levels Test well discriminates learners with a wide range of proficiency levels. The findings of the study are discussed, along with further improvements in order to ascertain the validity of this particular vocabulary test.

View From the point of change of the land of the land of the nation. The advancement in the modern civilization has led to building many apartments characterized by high buildings and building complexes due to population concentration into big cities. This tendency not only causes serious problems in terms of city images but also produces considerable discords in the matter of harmonized beauty of the complex itself.At the stage of space planning for the apartment complexes only economic and functional aspects were considered. So in many cases the space, which dose not contribute to environmental improvement which must go in parallel with the quantity increase of apartments and improvements of welfare and living standards of the apartment inhabitants.

The lacquer is one of the most important resources for endogenous development and cultural reproduction in Wonju. However traditional and social network, which had been formed by lacquer farmers, group of lacquer-pickers, refineries, and lacquer-ware craftsmen, is being collapsed. It is due to the recent imports of raw lacquer from China and refined lacquer from Japan. Public sectors including Wonju city have continuously improved the potential of lacquer production by planting lacquers. However, the potential of lacquer production isn't under enough condition to realize its value. In this study, it is suggested that the efforts of public sectors to raise lacquer industry, focused on the improvements of lacquer production potential until now, should be concentrated on realization of the production potential by reconstructing social productive system which is composed of diverse groups involved in lacquer ware production.

Interfacial and microfailure properties of carbon fiber/epoxy composites were evaluated using both tensile fragmentation and compressive Broutman tests. A monomeric and two polymeric coupling agents were applied via the electrodeposition (ED) and the dipping applications. A monomeric and a polymeric coupling agent showed significant and comparable improvements in interfacial shear strength (IFSS) compared to the untreated case under both tensile and compressive tests. Typical microfailure modes including cone-shaped fiber break, matrix cracking, and partial interlayer failure were observed under tension, whereas the diagonal slipped failure at both ends of the fractured fiber appeared under compression. Adsorption and shear displacement mechanisms at the interface were described in terms of electrical attraction and primary and secondary bonding forces.

A series hydraulic hybrid vehicle(SHHV) concept has been explored as a potential pathway to an ultra-efficient city vehicle. Improvements in SHHV fuel economy with reduced emissions strongly depend on their supervisory control strategy. Thermostatic control is simple and reliable but it's cause of frequent engine on-off. Therefore, power follower strategy is presented. In this paper, thermostatic control strategy and power follower strategy is compared for the SHHV model developed using AMESim.

Rapid urbanization, resource depletion, and limited land are further increasing the need for skyscrapers in city centers; therefore, it is imperative to enhance tall building performance efficiency and energy-generative capability. Potential performance improvements can be explored using parametric multi-objective optimization, aided by evaluation tools, such as computational fluid dynamics and energy analysis software, to visualize and explore skyscrapers' multi-resource, multi-system generative potential. An optimization-centered, software-based design platform can potentially enable the simultaneous exploration of multiple strategies for the decreased consumption and large-scale production of multiple resources. Resource Generative Skyscrapers (RGS) are proposed as a possible solution to further explore and optimize the generative potentials of skyscrapers. RGS can be optimized with waste-energy-harvesting capabilities by capitalizing on passive features of integrated renewable systems. This paper describes various resource-generation technologies suitable for a synergetic integration within the RGS typology, and the software tools that can facilitate exploration of their optimal use.

The goal of this study is to analyze an effect of productivity elevation. For the goal, the various methods of the productivity elevation were suggested and the system improvements were conducted. The S company was established in Ban-Wol Industrial Complex, Ansan-City, Kyonggi-Do on 2007. The company was hiring 22 employees. The main manufactures were heavy duty equipment parts and the amount of sale was two billion won on 2008. Problems which the company faced were ambiguous production target management and materials loss. To solve the problems, NCT work improvement and automatic welding were induced. There were steel saving of 3,780,000won/month and man-hour saving of 144,000won/month by redesign of the steel sheet for the NCT steel job. Also, changing from handwork to automatic welding, the man-hour saving for the welding job was 320M/H and saving of 4,225,600won/month. The others of systematic improvement for productivity elevation were usage of jig and daily equipment checklist.

There has been many improvements on our nation's public restroom, however, it was focused on interior decoration and installing convenience supplies. The simplicity of materials is another aspect. Besides, the lack of harmony with the surrounding scenery is also a problem. The new concept of public restroom that this study suggests is; a creation of a lively space to stimulate the senses of human and a cultural space that people can rest, and eventually improving the quality of life, being the landmark of streets and parks by avoiding the negative image.

Constructed wetlands provide several benefits that are not solely limited to storm water management and are becoming common in storm water management. In this research, four recently constructed wetlands underwent in situ and laboratory water sampling to determine their efficiency in removing storm water pollutants over a 5-month period. From the sampling results, it was determined that each of the wetlands was able to reduce the concentration of pollutants in the stormwater. To aid in the assessment of the wetlands against each other, a model was developed to determine the extent of removal of stormwater pollutants over the length of the wetland. The results from this model complimented the data collected from the field. Improvements, such as increased amounts of vegetation were recommended for the wetlands with the aim of increasing the effectiveness. Further investigations into the wetlands will allow for better understanding of the wetland's performance.
