การวิเคราะห์หาปริมาณโปรตีน แร่ธาตุและวิตามินในข้าวพันธุ์พื้นเมืองของจังหวัดเลย
The aim of this research was to study protein mineral and vitamin contents in 20 local rice varieties by collecting 36 samples from loei province. Determination of nutritional value of 36 samples showed that it consisted of 7.16±0.15-11.05±0.12 g protein/100 g rice. Khao Niaw Dum Luempua (LR22) showed the highest phosphorus content were 263.85±0.19 mg/100 g. Analysis the amount of iron and calcium by flame atomic absorption spectrophotometry (FAAS). Found that the concentration of iron was the highest content in Khao Homtung (LR7) were 7.31±0.14 mg/100 g And calcium content highest in Khao Niaw Dum Luempua (LR22) as 11.15±0.24 mg/100g. In the analysis of all three vitamins by high performance liquid chromatography (HPLC). khao Sum Bine (HP14) showed the highest beta carotene content were 0.08±0.14 mg/kg. While not detecting beta carotene in local rice varieties 15 samples including Khao Plah Sew Noi detecting beta carotene in local rice varieties 15 samples including Khao Plah Noi (LR3) Khao Hom Sa Ngiem (LR6) Khao San Pa Tong (LR12) Khao San Pa Tongdor (LR13) Khao Soviet (LR15) Khao San Ti Bal (LR16) Khao Lom Pee (LR17) Khao Laotaek (LR19) Khao Plah Sew Noi (LR20) Khao Hom Sa Ngiem (LR27) Khao Homtung (LR28) Khao Phare (LR30) Khao Maw (LR31) Khao Dang (LR32) and Khao Plah Sew Noi (LR35). The results showed that the highest alpha tocopherol and thiamine contents were found in khao Niaw Dum Luempua (LR36) with 16.18±0.09 and 12.08±0.18 mg/kg respectively. The results of this study are useful as basic data for rice consumption local rice preservation and further product development.
เปรียบเทียบประสิทธิภาพการส่งกำลังไฟฟ้าระหว่างหม้อแปลงแกนอากาศและหม้อแปลงแกนเหล็กของวงจรขยายกำลังคลาสอี
This paper presents the simulation and experimental result of class-E power amplifier. It is often used in designing a high frequency ac power source because its ability to perform the conversion efficiently even at high frequencies with significant reduction of switching losses. This paper aims to compare the transmission performance of electrical power between the air core transformer and iron core transformer which the identical input voltage of 50 VAC. Both transformers are designed to step voltage up (step up transformer) ratio of 1:4.5. The Arduino microcontroller Arduino was used to generate a pulse width modulation (PWM) with operating frequency of 3.74 kHz. IC gate drive TC4422 was used to drive the IRF510 MOSFET. Based on the simulation and experimental results the power loss in air core transformer is 75 percent while power loss in iron core transformer is 0.2 percent. The maximum distance that can transmit electric power of air core transformer is 9.3 centimeters.
กรอบแนวคิดรูปแบบความสัมพันธ์เชิงสาเหตุของปัจจัยที่ส่งผลต่อการพัฒนาองค์กรปกครองส่วนท้องถิ่นสู่การเป็นองค์การที่มีขีดสมรรถนะสูงในประเทศไทย
This article aims at reviewing literature and supposing the hypotheses that present a conceptual framework of a causal relationship model of factors influencing the development of local administrative organizations into high performance organizations in Thailand. From the literature reviews some important points to be tested were found as follows: 1. The compositions of local administrative organizations development into high performance organizations consisted of 6 factors: 1) Total Management Quality; 2) Openness and Action Orientation; 3) Long-term Orientation; 4) Local Innovation Continuous Improvement and Renewal; 5) Quality of Human Resource Management System and 6) Readiness for Change of local Personnel. 2. The causal relationship model of factors influencing the development of local administrative organizations into high performance organizations are as follows: 1) Transformational leadership has a positive direct effect on high performance local administrative organizations; 2) Organizational culture has a positive direct effect on high performance local administrative organizations; 3) Organizational structure and design have a positive direct effect on high performance local administrative organizations and 4) Transformational leadership has a positive indirect effect on high performance local administrative organizations through organizational culture and organizational structure and design. This framework can be used to study and test against empirical data.

The purpose of the study was to synthesize the element of educational management to develop graduates of mass communication in digital era according to the views of experts. The data were collected by an in-depth interview using structured interview about of mass communication education in social context and digital era from 16 experts who were academics and professionals in mass commmunication. Data analysis and synthesis by using data synthesis tables to classify elements of education. It was found that: There were three main elements and 28 minor ones of educational management forms as follows: (1) Curriculum: knowledge of mass communication perception of media contexts interdisciplinary knowledge writing and communication skill and the integration of contents. (2) Learning management: analysis thinking development critical thinking development creative thinking development communication skill flexible learning cooperative learning action learning experiential learning to build new paradigm development of morals and work ethics professional skills integration and content management media convergence and cross-platform media nurturing of volunteering spirit and social responsibility technology literacy skills technical visits to mass communication organization. (3) Learning environment: sufficient equipment updated technology work space sightseeing activity corner covered network and accessibility news and information cornerand student work exhibition corner.

This research aims to 1. Study the Tourists’ Satisfaction toward Amenities on Burmese temple’s in Lampang and 2. Study the opinion of community toward Amenities on Burmese temple’s in Lampang. The research population is 280 people by interviews and surveys. Research conducted between January 2017 to June 2017. From the history of Lampang. There is a temple built by the Burmese or a fine art form on architecture fabrication together with the Buddha’s appearance is a Burmese and in the past even a monk is a Burmese who has traveled to Thailand. As a result Lampang is another province. The temple is built in the beautiful Burmese architecture. Let’s learn to learn many. But it is not widely known The research found that The most popular tourist destinations are Wat Pa Fang Wat Si Chum Wat Si Rongmuang Wat Mon Poo Yak Wat Mon Cham Sin Wat Tha Ma O Wat Chai Mongkol is a measure of importance. Has a long history Value for conservation. The art of faith religion history. It has not been well managed and has not the potential to provide for Cultural Tourism. However after the Tourism Authority of Thailand launch campaign of 12 cities you Can’t Say No. Lampang is one of the provinces in the project. The researcher is expected that Lampang and the Tourism Authority of Thailand are cooperating to discuss and generate models of cultural activities for the development of touring sites in Lampang.
