This research aimed to study the personal factors operation and effectiveness of the lunch management project in Central Special Education Center Bangkok. The comparison of the effectiveness of the lunch was based on respondents’ individual factors this study proposed guidelines for optimizing the lunch arrangements. The research group consisted of 215 parents administrators and persons in charge of lunch management of which 164 samples were divided into 140 parents and 24 administrators and responsible persons for the lunch. The research instrument was a survey questionnaire. Data were analyzed statistically by using frequency percentage mean standard deviation and one-way analysis of variance. The results of the study indicated that this sample of parents was predominantly female aged between 31 to 40 years holding a lower bachelors’ degree and having a maximum income of 10000 baht. Overall the operations of the lunch project were performed at a high level. It appeared that the raw materials had the most average followed by administration management. The personnel aspect was the least. Moreover parents’ perception towards the effectiveness of the lunch project were high. Considering each aspect ordered from the highest to the least they respectively included quantity type quality of lunch safety and health administration and favorite luncheon menus. The comparison of the effectiveness of lunch project management and the perception of parents classified by their personal factors revealed that there was a significant difference at 0.05. The found guidelines for increasing the effectiveness of the lunch projects were to provide quality food ingredients the variety of tasty and nutritious dishes and five food groups. Moreover recruited dietitians were required to cook clean disease-free and healthy food by either frying steaming boiling or grilling the food. As a result of fully utilizing nutrients students would stay fit and healthy.

This research is a survey study. And analyze the waste composition And guidelines for the use of seafood waste in the Thai seafood market Samut Sakhon Province According to the survey 96.27 percent of the waste comes from restaurants. This is because Most fresh seafood restaurants Will feed the seafood whole Therefore there is no garbage such as shrimp if it is a restaurant the customers will have left shrimps on the head. But the fresh restaurants give away the shrimp and crab so the garbage from the fresh restaurant only has fishbone which is very small. Because most customers accept the whole fish There were also some places where the vendors cut the fish and left their bones. But when analyzed by type of waste it found that shell waste was the highest. Which is up to 55.29 percent. Followed by shrimp shells fish bone and fish heads and crab shells the study found that seafood debris had material properties with low moisture content. It also contains calcium as the main component. For example shellfish contain calcium as the main component which is found in approximately 98.50 percent. Not only striped shells Fishbone shrimp and crab shells are also low humidity and high in calcium. The bizarre one was holding a sea bass head and a grouper head with a high amount of organic matter. And with low ash content food waste that should be analyzed for the possibility of recycling are striped shells cockle shells shrimp shells fishbone shells fishbone dumplings tuna and crab shells.

The purposes of this study were 1) to study the operating status of knowledge management of the Faculty of Liberal Arts. 2) to study the problems of knowledge management of the Faculty of Liberal Arts. 3) to present the development form of knowledge management system of the Faculty of Liberal Arts. This research was a qualitative research. Analytical unit was Faculty of Liberal Arts Rajamangala University of Technology Phra Nakhon. The population was the staffs of Faculty of Liberal Arts. The samples were randomly assigned to 8 persons divided into 2 groups: 4 administrators 4 teachers. Research tools were related documents and semi structured interviews.The process of conducting research was to study and analyze the concept theory from Documents to create an interview form collected data from the interviews and analysThe results were found as follows: 1) the operating status of knowledge management of the Faculty of Liberal Arts was 3 steps; Steps to determine the authority structure of the responsible person to proceed knowledge management and the process of knowledge management. 2) The problems of knowledge management of the Faculty of Liberal Arts were 4 sides; (1) By Staffs : The staffs had a lot of obligations lack of leadership Lack of understanding with knowledge management. (2) By organizational structure : Because knowledge management section was not organized into organizational structures it is unclear about budget allocation for activities and allocation support personnel. (3) By organizational culture; it was not conducive to knowledge management. (4) By motivation : Motivation for control of knowledge is management was not clear such as awards. 3) the development form of knowledge management system of the Faculty of Liberal Arts was to consist of 5 keywords; Assignment Creation Usage To give Success. The explanation was as follows; Assignment It means a clear policy and accepted by all parties. Creation it means the creation of staffs to understand knowledge management and the creation of organizational culture into the learning organization. Usage it means to use information technology to help knowledge management and to use knowledge management processes. To give; it means to give a reward for motivation to participate in knowledge management activities. Success; it means all staffs must have the same goal: the success of being a truly learning organization.

The purpose of this research the study of the potential of Suphanburi area for planting investment. In which the researcher has studied the soil data set that is different in each area of Suphanburi. That is quite diverse if divided by each district in Suphanburi province themselves from the basic information report in Suphanburi and the agricultural information of Suphanburi for the year 2017 when comparing with the soil set of Suphanburi it can be seen that the cultivation is quite comprehensive all. Although there are cultivated plants in Suphanburi farmers must consider the amount of water sufficient for cultivation. Topsoil maintenance in the case of repeated planting of crops in 1 year to obtain quality produce and prices. At times the agricultural market prices dropped. Farmers will have to modify the cultivation to meet the market demand. Or the cultivation of plants by considering the amount of water that is used in the cultivation as well.

The objectives of this research are to study the rate of deterioration of tyre friction coefficient and investigate the quality of new and old tyres that are currently in use. A set of the rolling resistance testing was designed and set up to work with the single dynamometer according to speed 80 km/h tire load 4660 N and inflation pressure 30 psi. There were three tire samples new tire one year used tire and two year used tire to find the rolling resistance coefficients. The finding shows that the rolling resistance was inverse variation with tire aging. For instance the new tire (1st sample) had the highest rolling resistance on the other hand the two year used tire (3th sample) had the lowest rolling resistance. Moreover the rolling resistance coefficients were inverses variation with tire aging. Besides the one year used tire had the average of the decreasing rate of the rolling resistance coefficient at 0.03689 N/kN per a week while the two year had the average of the decreasing rate of the rolling resistance coefficient at 0.03671 N/kN per a week. Furthermore the result also revealed that the rolling resistance coefficients nonlinearly decreased comparing to the tire aging.
