We have recently removed four interesting foreign bodies uneventfully. Case 1: Ten Won coin lodged over 8 months in the mediastinum of a 5 year old boy, which was removed surgically. Case 2: A balloon flute reed which made the sound of a flute when the child inhaled, in the right main bronchus of a 8 year old boy. Case 3 and 4: Two overlapped coins in the first isthmus of esophagus in both a 5 year old boy and a 5 year old girl.

Several interesting and useful extensions of some familiar special functions such as Beta and Gauss hypergeometric functions and their properties have, recently, been investigated by many authors. Motivated mainly by those earlier works, we establish some fractional integral formulas involving the extended generalized Gauss hypergeometric function by using certain general pair of fractional integral operators involving Gauss hypergeometric function $_2F_1$, Some interesting special cases of our main results are also considered.

As a new way to explore the universe, astronomers are now performing time-domain astronomy by surveying the universe looking for new transient phenomena and taking movies of the universe with telescopes. Large-area, time-series survey of astronomical objects are uncovering many interesting, fast-changing objects that have now been poorly understood before, such as GRBs, tidal disruption phenomena, and new types of supernova. In order to characterize these new, exciting events, it is very critical to perform follow-up observations, and 1-2m telescopes can effectively contribute to such efforts. Since 2007, our group has been performing follow-up observations of gamma-ray bursts (GRBs) and interesting transients using BOAO and other KASI facilities. Here, we present results from several key transient studies that were done by using BOAO: (1) tidal disruption event Swift J1644+57; (2) SN 2011fe that occurred in M101; and (3) several GRB events. These study demonstrates the usefulness of BOAO as a powerful transient follow-up facility. Finally, we will discuss how BOAO research activities can possibly be bolstered in this newly emerging field of astronomy.

Most statistical methods for finding interesting genes are focusing on the summary values with large fold-changes or large variations. Very few methods consider the probe level data. We developed a new measure to detect reliability that incorporates the probe level data. This reliability measure is useful for exploring the microarray data without ignoring the probe level data. It is easy to calculate, and it can be used for all the other statistical methods as a good guideline to find real differentially expressed genes. Instead of filtering out genes before the analysis, we use whole genes in the analysis and make decisions with new reliability measures.

Astronomy is one of the interesting but difficult topics in science for elementary education. Therefore, it is interesting to create astronomy activities that children can understand clearly. The researchers developed activities by using astronomy and botany to improve writing skills. They have to glue the local flowers on the star pictures then write the name of those flowers, the name of the constellation and write an essay describing their work. The participants are into two groups. 71 $3^{rd}$ year undergraduate students who registered for teaching and are learning science as an elementary education subjec, and 10 $1^{st}$ grade student from the laboratory school of Ubon Ratchathani Rajabhat university. We can conclude that both groups were more interested in astronomy, they can tell the name of local flowers and not only used their imagination to create their work, but also to write great essays.

The Clausen function $Cl_2$(x) arises in several applications. A large number of indefinite integrals of logarithmic or trigonometric functions can be expressed in closed form in terms of $Cl_2$(x). Very recently, Choi and Srivatava [3] and Choi [1] investigated certain integral formulas associated with $Cl_2$(x). In this sequel, we present an interesting new definite integral formula for the Clausen function $Cl_2$(x) by using a known relationship between the Clausen function $Cl_2$(x) and the generalized Zeta function ${\zeta}$(s, a). Also an interesting integral representation for the Catalan constant G is considered as one of two special cases of our main result.

Very recently, Srivastava et al. [8] introduced an extension of the Pochhammer symbol and used it to define a generalization of the generalized hypergeometric functions. In this paper, by using the generalized Pochhammer symbol, we extend the generalized Hurwitz-Lerch Zeta function by Goyal and Laddha [6] and investigate some interesting properties which include various integral representations, Mellin transforms, differential formula and generating function. Some interesting special cases of our main results are also considered.

To assist developing robust multithreaded software, we develop a thread monitoring system for multithreaded Java programs, which can trace or monitor running threads and synchronization. We design a monitoring system which has options to select interesting threads and synchronizations. Using this tool, programmers can monitor only interesting threads and synchronization in more details by selecting options. It also provides profile information after execution, which summarizes behavior of running threads and synchronizations during execution. We implement the system based on code inlining, and presents some experimental results.

WTO was established in 1995 and as many as 36 new members joined WTO until December 2017. Thus it would be interesting to see if new members have committed higher or lower levels of market opening compared to the original members. In this regard, a sophisticated scoring scheme is needed to quantify market opening commitments. After proper econometric model is established for the original members, same model can be applied to the new members for comparison. It was found that new members committed a much higher level of commitment than the original members. In addition, it was also found that transition economies committed higher levels than the non-transition economies. More interesting finding is that among the new members, the larger the economies or the larger the trading volume are, the closer was the level of commitment to the predicted level. Then the question is whether this difference was due to benign neglect by the new members or due to malign select by the original members.

We have recently removed three interesting foreign bodies uneventfully. Case 1: In 20 years old boy, the bullet which penetrated his trachea and esophagus through, lodged on second thoracic vertebra. Case 2: In 1 5/12 year old boy, 52 cm metallic neck lace was hung on the bifurcation of bronchus. Case 3: In 17 years old boy, the pin was stuck in the wall of his esophagus.
