Nowadays advanced manufacturing companies are trying to find a way to check the performance of their production equipments and plants from remote sites. However, it is hard to monitor the status of machine or to check the performance of the processes because the regional limitation of distributed environment. This paper presents research results in the real time monitoring of machining processes and internet_based operation of machining centers via internet, which is implemented using VRML and JAVA.

This research proposes the importance of physical environment if integrated early childhood education. For a successful integration of children's education, we processed fundamental research on requirements of facility and equipments, looking at related standards and code on handicapped person's convenience facility. Also, this research alms at providing first step to establish evaluation method and quality assurance standards of integrated child care facility, regarding space planning of handicapped children. By examining home and abroad material and analyzing handicapped children's convenience facility standards, this research pursues improving the basis of planning criteria. As present criteria of relevant regulations appears not to handle detailed facility standards, and the handicapped people's facility is for childhood education, it is necessary first to differentiate indispensable equipments from optional one, then categorize them into more specific needs.

The objective of the study is to observe cooks first from the kitchen and those who care health and to grasp the impression regarding the kitchen environment. Also, it grasped the recognition degree of cooks against the elements of kitchen ventilation and kitchen ventilation equipments. We surveyed against 385 cooks who work in the kitchen of special grade hotels and family restaurants, used 5 scales for the object, and executed the analysis. The results of this study are as follows: (1) Health condition of the cooks appeared most highly pain in the shoulder and the neck. (2) for the impression regarding the kitchen environment, temperature was high and the insufficiency of ventilation is answered highly. (3) The importance of kitchen ventilation of cooks was recognized very high. (4) The combustion gas was recognized as very high percentage and the most effective element of the kitchen on the human body to remove first inside the kitchen. (5) Most cooks were recognized that the improvement of ventilation equipments is necessary. (6) The object of ventilation equipments is appeared to maintain comfortable kitchen environment. (7) The optimum operation method of ventilation equipment uses the automatic system of ventilation equipment from the kitchen and it is necessary to maintain the optimum. This research is based on preceding studies, investigating special grade hotels and family restaurants in Seoul. The ventilation plan of the kitchen should be accomplished to improve the health of cooks and productivity.

The temporary tax deduction on investment cutting the corporate income tax within 10% of the amount of investment is aimed at stimulating the investment for economic activity. 25 business sectors are applied to this tax law and in tourism, the accommodation registered by tour promotion law and international convention plan business belong to it. I'd like to mention the problem of the temporary tax deduction on investment amount for hotels and suggest better solutions. This tax law is so temporary applied that we shouldn't get tax deduction after June 30, 2002. So, we can't get income tax deduction on the investment out of the available period. And further more this tax law has a rule not real investment but solely new project investment for hotels. There are numbers of difference between real investment and new project investment. The amount of investment is based on an object of acquisition taxation. And also there are numbers of difference between real investment and an object of acquisition taxation. For example, landscape construction is a great part of hotel construction but it's not an object of acquisition taxation. For running hotel business, we also need lots of equipments such as linens utensils for restaurant and decorations for hotel interior. But these are also excluded from this tax law. As you know, these equipments can be regarded as product equipments in manufacture industry. Therefore we should take the specificity of hotel investment into consideration and expand the role of the temporary income tax deduction on investment amount for hotels.

It is the most important subject to figure out characteristics of the wastewater inflows of sewerage treatment plant(STP) when situation models are applied to operation of the biological processes and in the automatic control based on ICA(Instrument, Control and Automation). For the purposes, real-time influent monitoring method has been applied by using on-line monitoring equipments for the process optimization in conventional STP. Since, the influent of STP is consist of complex components such as, COD, BOD, TN, $NH_4$-N, $NO_3$-N, TP and $PO_4$-P. MRA2(Microbial Respiration Analyzer 2), which is capable of real-time analyzing of wastewater characteristics is used to overcome the limitations and defects of conventional online monitoring equipments in this study. Rapidity, accuracy and stability of developed MRA2 are evaluated and compared with the results from on-line monitoring equipments for seven months after installation in Full-scale STP.

The Korean Government is promoting Korean Land Spatialization Program(KLSP) to commercialize and practice of the technology from 2006 to 2012. It is preparing for field test to make research achievements verified in Sejong City by selecting a test-bed area. It creates the conditions to be satisfied standards that can be recognized at internal and external. This paper proposes to design a test bed considering site conditions and various requirements for performance verification of Surveying Equipments in KLSP.

KTX train system is composed of TORNAD* network for transmitting information of train's internal equipments and OBCS which proceed information within train. OBCS of one trainset consisted of 28 equipments takes intelligent and dynamic composition according to equipment handling, train command and control flow. Each OBCS which is installed within trainset handle and supervise mutually action information about equipments, transmit it to driver to transmit information about train operation and preventive management. This mutual supervision and information transmission use KTX TORNAD* network system. TORNAD* network system is the one which is uniquely developped by GEC ALSTHOM, the KTX trainset manafacturing provider and this field is excluded from technical know-how transfer item. Through the research on analysis method of KTX TORNAD* system data structure which is operating on Seoul-Pusan Line, I hope that this thesis can contribute to train network system's standardization after applying it to improvement of train network system maintenance, enhancing quality of train service and applying it to future Korean rolling stock network system development.

This survey was conducted to evaluate the microbial contamination level of butcher's shops in Seoul, Korea. For microbial inspections, a total of 584 samples (146 cotton work gloves, 146 utensils and equipments, 154 beef samples, 138 pork samples) were collected from butcher's shops. E. coli and pathogenic bacteria such as Staphylococcus aureus, Yersinia enterocolitica, Listeria monocytogenes, Salmonella spp., and E. coli O157:H7 were tested in the samples. As a result, the level of aerobic plate count (APC) ranged ${\leq}10^4\;CFU/cm^2$ from utensils and equipments, $10^1{\sim}10^9$ CFU/glove from cotton work gloves and ${\leq}10^6$ CFU/g from meat. The APC level of E. coli ranged ${\leq}10^1\;CFU/cm^2$ from utensils and equipments, ${\leq}10^5$ CFU/glove from cotton work gloves, and ${\leq}10^3$ CFU/g from meat, respectively. Staphylococcus aureus was detected in 2 beef samples, 1 pork sample, and 10 used cotton work gloves. Yersinia enterocolitica was detected in 3 beef samples, 1 pork sample, and 3 used cotton work gloves. Listeria monocytogenes was detected in 2 used cotton work gloves. In order to improve the sanitation status of butcher's shops, application of HACCP (Hazard Analysis Critical Control Point) or SSOP (Sanitation Standard Operating Procedure), regular hygiene education, and continuous monitoring for microorganisms will be required.
