title: Helping or not Helping? Why and How Trivial Packages Impact the npm Ecosystem

description: Developers often share their code snippets by packaging them and making them available to others through software packages. How much a package does and how big it is can be seen as positive or negative. Recent studies showed that many packages that exist in the npm ecosystem are trivial and may introduce high dependency overhead. Hence, one question that arises is why developers choose to publish these trivial packages. Therefore, in this paper, we perform a developer-centered study to empirically examine why developers choose to publish such trivial packages. Specifically, we ask 1) why developers publish trivial packages, 2) what they believe to be the possible negative impacts of these packages, and 3) how such negative issues can be mitigated. The survey response of 59 JavaScript developers who publish trivial npm packages showed that the main reasons for publishing these trivial packages are to provide <em>reusable components</em>, <em>testing</em> & <em>documentation</em>, and <em>separation of concerns</em>. Even the developers who publish these trivial packages admitted to having issues when they publish such packages, which include the <em>maintenance of multiple packages</em>, <em>dependency hell</em>, <em>finding the right package</em>, and the <em>increase of duplicated packages</em> in the ecosystems. Furthermore, we found that the majority of the developers suggested grouping these trivial packages to cope with the problems associated with publishing them. Then, to quantitatively investigate the impact of these trivial packages on the npm ecosystem and its users, we examine grouping these trivial packages. We found that if trivial packages that are always used together are grouped, the ecosystem can reduce the number of dependencies by approximately 13%. Our findings shed light on the impact of publishing trivial packages and show that ecosystems and developer communities need to rethink their publishing policies since it can negatively impact the developers and the entire ecosystem. The published data set contains the following: List of identified trivial npm packages. The survey questions. The developers' responses to the survey. The results of the co-usage analysis of trivial npm packages.

title: Effects of blend compositions and additives on physical and mechanical properties of IDPE/EVA blend foams

description: The effects of dicumylperoxide crosslinking agent loading and modifiled azodicarbonamide with zinc oxide chemical blowing agent loading, ratio of LDPE/EVA at 70/30 and 80/20 wt/wt and vinyl acetate content in ethylene vinyl acetate copolymer at 18%wtVA and 28%wtVA on the physical and mechanical properties of LDPE/EVA blend foams were studied. LDPE were mixed with EVA and additives using twin-screw extruder. Polymer blend foam were produced by two-stage process; pre-foamed sheet were made by compression molder and expanded in hot air oven. The experimental results showed that increasing of crosslinking agent loading led to higher degree of crosslinking and lower foam density. However, the increasing of crosslinking agent loading together with increasing of chemical blowing agent loading led to higher foam density due to too high degree of crossling for the amount of chemical blowing agent used. Overall, the mechanical properties of obtained foams increased with increasing foam densities. Lower the foam density, softer and more flexible the foams became.

title: A decentralization model for the Bangkok Metropolitan administration in regulation of the retail pharmacy via Health Centers participation

description: The purpose of this research was to propose the decentralization model for the Bangkok Metropolitan Administration (BMA) in regulation of the retail pharmacy. This research was quantitative and qualitative methods. The quantitative method was to collect the questionnaire from directors and pharmacists of health centers. The qualitative method was to conduct a focus group discussion. The experts group from the BMA and Ministry of Public Health who had their work related with retail pharmacy regulation were selected to be in the focus group. The research found that 56.5% of directors and 92.1% of pharmacists agreed that the BMA should be responsible for retail pharmacy inspection. In addition, 40.3% of directors and 61.9% of pharmacists thought that the BMA should be responsible for approving pharmacy license. The results of study showed that the appropriate decentralization model should completely include the tasks of retail pharmacy license and retail pharmacy inspection, and it should cover all types of retail pharmacy. There were several agencies of the BMA which should be responsible for regulating the retail pharmacy, as following: 1) Agency to approve retail pharmacy license was Pharmaceutical Division 2) Agencies to inspect retail pharmacy were Health Centers with Pharmaceutical Division, which were supported by District Offices. 3) Legal process agency was Pharmaceutical Division 4) Agencies to receive drug complaints such as Hotline 1555, Hotline of Health Department, Pharmaceutical Division, Health Centers, and District Offices. The suggestion of this research to the executive of the BMA were allocating manpower and budget for this new task, and establishing the professional career for pharmacist in Pharmaceutical Division and Health Centers to be responsible for this new responsibilities.

title: α-Glucosidase inhibitors from abelmoschus esculentus seeds and Schinus terebinthifolius leaves

description: Discovery of α-glucosidase inhibitors has been actively pursued with the aim of developing therapeutics for the treatment of type 2 diabetes mellitus. In examining inhibitory effect of edible plants, extracts of Abelmoschus esculentus seeds and Schinus terebinthifolius leaves revealed promising results, and they thus were selected for further investigation. The methanol crude extracts from seeds of A. esculentus afforded two flavonoid glycosides named, quercetin-3-O-β-glucoside or isoquercetin and quercetin-3-O-β-glucosyl (1'''→6'') glucoside. The isolated compounds selectively inhibited α-glucosidase whereas their inhibition against α-glucosdase from baker’s yeast was not observed. Isoquercetin inhibited maltase and sucrase 6-10 times more potent than its related diglucoside, thus indicating that increased hydrophilicity by glucose moiety reduced inhibitory effect and aglycone quercetin is critical for enzyme inhibition. Quercetin prepaed from commercially available rutin was also examined for α-glucosidase inhibition. It showed board inhibition against α-glucosidase from baker’s yeast, maltase and sucrose with IC₅₀ value of 62.8, 12.32 and 31.69 µM, respectively. The kinetic study of quercetin showed competitive inhibition in sucrase whereas mixed type inhibition against maltase was observed. The methanol crude extracts from Schinus terebinthifolius leaves afford 3 hydrolysable tannins named methyl gallate, b-glucogallin, 1,2,3,4,6-pentagalloyl-O-β-D-glucopyranoside (PGG) and inositol. PGG revealed highest inhibition against maltase and sucrose with IC₅₀ values of 27.21 and 37.53 µM, respectively. The kinetic analysis of PGG showed mixed type inhibition against maltase and sucrase. In addition, PGG showed dominant synergistic effect in rat intestinal maltase, thus leading to 7.1% and 7.9% higher inhibition. Notably, the kinetic analysis and synergistic effect of PGG is first report herein.

title: The Role of military in disaster relief : case study on the relationship between the Royal Thai Army and government agencies in flood 2011 in Bangkok

description: This study focuses on the role of the Royal Thai Army (RTA) in disaster relief operations during the flood 2011 in Bangkok. This is aimed to understand the fundamental barriers faced by the RTA in interfacing with government agencies in disaster relief operations. It also analyzes the weaknesses of the existing interfacing mechanism as well as determines the possible ways in minimizing the fundamental barriers for the interfacing process with government agencies. The study uses qualitative approach for the case-study, utilizing content analysis of written materials and key informant interviews in the form of semi-conducted style on the RTA units and key government agencies who were involved in the disaster relief operation during the Thailand Flood in 2011 in Bangkok. This study uses the Coordination Model, developed by the National Institute of Justice, the United Stated Department of Justice, to analyze the qualitative data from the interviews. This study revealed that the difficulties for the RTA can be categorized at two levels, policy level and operation level. There is also some gap between these levels during the disaster relief operations in the flood 2011 in Bangkok, which helps to understand the difference in the thoughts and concerns of the personnel of both levels. However, one major common difficulty for both levels is the unawareness and unpreparedness for this prolonged flooding. The relief operations were done at hand with very limited knowledge and experiences, creating complexity in management of assistances. The vital concern at the policy level is the legal and structural aspect of barrier. The role of the military in disaster relief is stated to be the supporting one, which means that the RTA must only operate upon the requests of other agencies in disaster relief. At the operation level, it is found that the vital concern is the relief equipment as the existing equipment is not designed for relief operations in such prolonged flood situation. From this study, it is reflected that the collective awareness and preparedness for natural disasters are not thoroughly promoted nor productively utilized for national plan.

title: Health problem from working as Thai traditional massage therapists

description: Objective: To determine health problems of Thai traditional massage therapists (TTMs) who work at Thai traditional medicine units in general hospitals in Thailand. Method: A cross-sectional survey study in Thai traditional massage therapists in general hospitals in Thailand from March to July 2012 was conducted. The therapists completed self-administrated questionnaire. Results: About 60% of Thai traditional massage therapists practised both Common and Court-type Thai massage. The highest symptom of injury was lower back pain (82.2%) followed by upper back (80.2%) and neck (78.0%). The majority used incorrect posture which was the main cause from working while giving massage to the clients (76.1%). The posture mostly used kneeling on heels (75.9%) and the parts of the body mostly used were thumbs and knuckles (71.4%). This study showed the types of massage related to left shoulder pain (p=0.00) and the duration of working related to lower back pain (p=0.04). Conclusion: Duration of working, types of massage, long working hours, and incorrect postures affected the therapists.

title: Frequency-based steganography using 32x32 interpolated quantization table and discrete cosine transform

description: Image steganography is the art of hiding the existence of the information in the image. The steganography can be categorized into two types in spatial domain and frequency domain. In this study, the frequency based image steganography using Discrete Cosine Transformation (DCT) and JPEG is proposed. Instead of using 8x8-pixel blocks with the 8x8-pixel quantization table, a larger block of size 32x32 will be used with a corresponding 32x32-pixel quantization table created by cubic spline interpolation technique. The experimental results show that the computation time is reduced and the capacity of the secret messages is increased while maintaining the quality and the size of JPEG stego-image

title: Comparison of the use of omega-3 fatty acids compound from New Zealand green lipped mussel and fish oil in the treatment of canine shoulder and coxofemoral osteoarthritis

description: This study was designed to assess the effects of omega 3 fatty acids compound from New Zealand green lipped mussel (PCSO-524) and omega 3 fatty acids in fish oil on clinical outcomes and on osteoarthritis biomarkers (chondroitin sulfate WF6 epitope and hyaluronan (HA)) in 46 osteoarthritis (OA) dogs; 39 dogs with OA hip joints, 5 dogs with OA shoulder joints and 2 dogs with OA shoulder and hip joints. The animals were presented at the Small Animal Hospital, Faculty of Veterinary Science, Chulalongkorn University. The dogs were randomly allocated into 2 groups; PCSO-524 and fish oil groups fed with the two preparations for 8 weeks. Lameness score, weight bearing score, radiographic score, range of motion and serum OA biomarkers (WF6, HA) were evaluated before treatment and at 2, 4 and 8 weeks after treatment. Lameness score, weight bearing score and ROM were significantly improved within two weeks after PCSO-524 administration while there were no statistically significant difference in all parameters of the fish oil group. At 4 and 8 weeks, lameness and weight bearing scores of the PCSO-524 group were significantly improved as compared with the fish oil group. Although the mean of radiographic scores was not significant difference among groups, mean of serum WF6 of the PCSO-524 group (262.46±162.24 ng/ml) was significantly (p&lt;0.05) lower than that of the fish oil group (353.99±132.25 ng/ml) after eight weeks of administration. In conclusion, PCSO-524 administration could slow progression of osteoarthritis of the shoulder and hip joints in dogs.

title: Source tracking of Salmonella enterica in broiler production by Pulsed-Field Gel Electrophoresis (PFGE)

description: The objectives of this study were to determine the chronological dissemination and the main sources of Salmonella introduction to broiler production throughout rearing period by Pulsed-Field Gel Electrophoresis (PFGE). The samples were collected from a commercial broiler farm up to 3 cycle productions from a commercial broiler farm in Northeastern part of Thailand during 2010-2012. The samples were collected from the same broiler house and the total number of samples from broiler and environment were 1,350 and 697, respectively. The isolates with common Salmonella serotypes between broiler and environment were chosen for source tracking by subtyping with PFGE. The result from the first flock showed that contaminated water and new feed were possibly the primary sources of Salmonella to the broiler flock because of the identical PFGE pattern of S. Albany (subtype ABa1) and S. Derby (subtype Da1) among feed, water and broiler. The contaminated water was also possibly the source of Salmonella contamination to broiler house and equipment because S. Albany PFGE subtype ABa1 was found from both water and broiler house equipment after disinfection. Salmonella isolates were not detected from broiler in the second flock. However, the same PFGE subtypes of S. weltevreden (subtype Wa1, Wa2) from house lizards and environment between the first and the second flock were found. The result indicated that house lizards may act as a reservoir between flocks. In the third flock, S. Corvallis (PFGE subtype Ca1) was found from the day old chick. This PFGE subtype was also found throughout the rearing period from broiler and also from pest and environment in the broiler house. So, the contaminated day old chick was the main source of Salmonella contamination in this flock. In conclusion, this study suggested that contaminated water and feed including infected day old chick were among the main sources of Salmonella contamination in broiler farm. In addition, the contamination of house and equipment, litter, transportation equipment and pest should also be concerned as a possible source of Salmonella contamination in broiler flock.

title: Reduction of benzene in reformate by ethylene alkylation with benzene

description: Benzene is a key aromatic hydrocarbon which is an important high octane component of motor gasoline; however, benzene is known as a human carcinogen and also has high vapor pressure thus high evaporative emissions. Reformate is the largest portion of benzene in a gasoline pool and, therefore it was aimed to reduce benzene content prior to blending. Alkylation of reformate with ethylene was investigated in this research work. The reaction was performed in an autoclave reactor with a temperature of 225 °C and pressure of 45 bar for 20 h using β- zeolite as a catalyst. The alkylation products showed the increasing in research octane number (RON) and distillation temperature with decreasing in blending Reid vapor pressure (bRvp) because ethylbenzene is produced instead of benzene. Thus the process improves gasoline quality in both term of technical and environmental viewpoint. Benzene conversion is higher with higher ethylene in feed. Moreover, modified β-zeolite with Ga further improved benzene conversion and RON with decreasing bRvp. However, this improvement with Ga modification might not because of the enhancement of alkylation between benzene and ethylene as proven by the probe reaction of pure benzene with ethylene.

title: Joint source channel error-resilient video coding for wireless video transmission

description: Successful video communication over wireless channels is one of the most technically challenging problems in multimedia communications. The inherent vulnerability of compressed video to transmission errors and the time varying and fading environments of the wireless channel combined with network and application constrains presents some major technological issues that needs to be addressed. To improve the error resiliency and efficiency of transmitting video over wireless channels. Several techniques are developed that contribute to better utilize the error resilient features available in H.264 and propose enhancements to the frame layer rate control. Firstly, new techniques on how to use explicit Flexible Macroblock Ordering (FMO) more effectively in wireless video ransmission by using combined spatial and temporal indicators of macroblock (MB) importance to generate slice group maps for H.264. Secondly, an improved sorting algorithm that classifies macroblocks into different slice groups for FMO in H.264 that further improves the use of explicit FMO. Thirdly, enhancements to the H.264 frame layer rate control is proposed, that takes into consideration the effects of using FMO for video transmission, to better manage bit allocation and improve coding efficiency. We propose a new header bits model, an enhanced frame complexity measure, a bit allocation and a quantization parameter (QP) adjustment scheme. Lastly, a framework for adaptive FMO selection scheme based on feedback information is presented. In summary, in this dissertation we propose the framework of using explicit FMO, rate control and feedback information for wireless video transmission. Experimental results show that the proposed techniques are effective in improving the video quality especially for complex video sequences and at low-bit rates.
