The research population comprised 16 Karen hill tribe students at Prathom Suksa IV – VI levels of Ban Hua Mae Surin School in Mae Hong Son province. The employed research instruments were (1) a guidance activity package to enhance self-confidence; and (2) a self-confidence assessment scale, with overall reliability coefficient of .96. Statistics employed for data analysis were the percentage, mean, and standard deviation. The research results showed that the pre-experiment, post-experiment, and follow-up period self-confidence mean scores of Karen hill tribe students at Ban Hua Mae Surin School in Mae Hong Son province, who used a guidance activities package to enhance self-confidence, were different with their post-experiment mean score being higher than their pre-experiment mean score, and their mean score during the follow-up period being higher than their post-experiment mean score
Selective Aggregation of Polyanion-Coated Gold Nanorods Induced by Divalent Metal Ions in an Aqueous Solution
No full textA simple, accurate method for detecting metal ions in an aqueous solution using functionalized gold nanorods (AuNRs) is described. The method involves the complexing of divalent metal ions with poly(acrylic acid) (PAA) and, the localized surface plasmon resonance (LSPR) phenomena of AuNRs. Changes in the longitudinal surface plasmon bands (LSPBs) were monitored using aggregates of PAA-coated AuNRs with various divalent metal ions via UV-vis spectroscope. Functionalized AuNRs underwent robust aggregate formation by chelation with divalent metal ions (e.g., Cu2+, Zn2+, Cd2+, and Fe2+). Copper ions formed largest aggregates within 2 h, because complexation between Cu2+ and dicarboxylate has the highest Delta H and -Delta G values. This process represents an easy and useful method for detecting certain divalent metal ions, and the aggregates are also, in some cases, clearly visible to the naked eye

Pottery-making in Ban Mai, Muang District, Surin Province, Northeast Thailand and the paddle and anvil technique in Southeast Asia.
No full textThe making of pottery vessels for boiling cocons is extensively carried out in Ban Mai, Muang District, Surin Province, Northeast Thailand. The author investigated the characteristics and manufacturing of those vessels in August 1984. This article reports those findings and also the classification of those examples in Southeast Asia.
Pottery-making at Ban Mai goes through following manufacturing processes.① Gathering clay suitable for pottery.② Kneading and tempering the clay with sand of laterite.③ First stage of forming. Clay is formed into cylinder.④ Second stage of forming. The upper part of pot is formed using the paddle and
anvil. The rim is finished by a piece of cloth.⑤ First stage of Drying.⑥ Third stage of forming. The lower part and the base of pot is formed using the paddle and anvil.⑦ Second stage of drying.⑧ Baking.The pottery-making at Ban Mai is characterized by the forming of the clay into a cylinder by hand and the paddle and anvil technique. The pottery manufacture in
Southeast Asia commonly uses the paddle and anvil technique. Three different methods are seen at the first stage of forming, by potter's wheel, by turn table, and by hand only. And the method of forming by hand is classified into two methods, first, only by hand, second, by buiding a clay belt into a pot. We can see some stages of the technical development in the pottery-making of Southeast Asia. The pottery manufactured at Ban Mai is one of the most primitive in Southeast Asia

Suai liang chang haeng lumnam Mun moradok haeng chatphan Kui--Aching
No full textThe author writes about Kui or Suai, the indigenous people of the Northeastern Thailand. This indigenous group concentrates mostly in Surin and Sisaket. Also, there are some groups of them live in Ubonratchathani, Buriram, Nakhon Ratchasima and Mahasarakham. Kui's ways of life are tied closely to elephants. Kui men capture and domesticate wild elephants
Community Services by Haitian Churches in New York City as a Means of Fulfilling the Great Commission: A Qualitative Investigation
No full textThe respective research focuses on Haitian Christian leaders’, particularly Millennials’, perception of commitment to community service in the metro New York City area in their churches’ neighborhood. Prior to this present study, Haitian Christian leaders’ perception commitment to community service in their churches’ neighborhoods were unknown. Therefore, this present research created a measuring tool – “Rubric for Evaluating Commitment to Community Service” (RECCS) to assess Haitian Christian leaders’ perception commitment to community service. The present research author interviewed three leaders (senior pastors and two youth leaders) from five different churches totaling fifteen participants to determine their level of commitment to community service. Afterward, the present research author did a second interview with senior pastors of each church and searched for indicators of common traits/factors that three highest and the two lowest scoring churches had in common. The present research author discovered that the level of commitment to community service differ among the five churches and between senior pastors and their youth leaders. In addition, the research found that there were no common trait/factors among the highest scoring churches, but there was one trait in common among the lowest scoring churches. Despite this, that trait/factor could not yield a conclusion making the research results be inconclusive. Lastly, the present research author offered ministry recommendations to future research and the Haitian church community

Spectroscopic Analysis of NF3 Plasmas with Oxygen Additive for PECVD Chamber Cleaning
No full textAs semiconductors’ device fabrication is highly integrated, the number of the deposition processes is continuously increasing, and the chamber cleaning process becomes essential for deposition equipment to maintain a normal chamber condition. Although the use of NF3 gas for the chamber cleaning is common, it causes several environmental and safety issues. However, not much research has been performed on NF3 plasma at high pressures, such as in cleaning processes. To understand fluorine in NF3, herein, oxygen was added to N2 and NF3 plasma and then compared. Plasma emission spectra were compared using an OES data, and their analyses were performed via a line-ratio method employing the collisional-radiative model. As a result confirmed that the changes in electron temperature, electron density, and chemical species in the plasma could be explained. Additionally, the characteristics of NF3 plasmas with respect to fluorine were confirmed by comparing the oxygenated N2 plasma and the NF3 plasma

Physikalisches Institut, Universit\""{a}t zu K\""{o}ln, Z\""{u}lpicher Str.; Steacie Institute for Molecular Sciences, National Research Council of CanadaThe millimeter wave spectrum of the isotopically substituted CO dimer, has been studied for the first time, confirming and extending a recent infrared study [1]. A total of 87 transitions in the 77 - 180 GHz region have been assigned and analyzed with a model-independent term value scheme involving 57 rotational levels with to 8. The levels can be classified into 7 ``stacks'' which have symmetry classifications of either or , and K -values of either 0 or 1. For the normal isotope, symmetry and nuclear spin statistics cause alternate rotational levels to be missing, but for , all levels are present with an intensity alternation of 1:3 between the A and B symmetries. The four stacks have not previously been observed, and the lowest of them establishes the tunneling splitting of to be , slightly larger than the value [2] of . Even though a considerable amount of precise experimental data is now available for the CO dimer, we still have little theoretical insight into its structure and tunneling dynamics
