This paper presents a method to measure the similarity of assigned jobs in the gravure printing operation based on the chromaticity and color sequence, and order the jobs accordingly. The proposed dispatching rule can be used to fulfill diverse manufacturing site requirements because the parameters can be adjusted to prioritize chromaticity and color sequence. In general, dispatching rules either ignore the job-changing time or require that the time be clearly defined. However, in the gravure printing operation targeted in this study, it is difficult to apply the general dispatching rule because of the difficulties in quantifying the job-changing time. Therefore, we propose a method for generalizing assignment rules of the job planner, allocating relative similarity among assigned jobs, and determining the sequence of jobs accordingly. Chromaticity priority is determined by the arrangement of the color assignments in the printing operation; color sequence priority is determined by the addition, deletion, or change in a specific color sequence. Finally, the job similarity is determined by the dot product of the chromaticity and color sequence priorities. Implementation of the proposed dispatching rule at an actual manufacturing site showed the planner present the same job order as that obtained using the proposed rule. Therefore, this rule is expected to be useful in industrial sites where clear quantification of the job-changing time is not possible.

The genus Pachynoa Lederer, 1863 reported 13 species in the world. This genus was established by Lederer, 1863 have been treated within the genera Pitacanda Moore, 1886 by Hampson, 1896 and Hypermeces Turner, 1933 by Shaffer et al., 1996. Species of the genus Pachynoa are mostly distributed from India and Taiwan to Solomon island. In this study, the genus Pachynoa is newly recorded in Laos with two species, Pachynoa xanthochyta (Turner, 1933) and Pachynoa thoosalis (Walker, 1859). These species are redescribed with illustrations of the adults and the genitalia, and their distribution is updated.

Laos is located in mainland of Southeast Asia, covered with 236,800 square kilometers. This country is located at the heart of the Indo-Chinese Peninsula and is surrounded by Myanmar, Thailand, Cambodia, Vietnam and China, providing a potential for a resource base and land- link in the Greater Mekong Sub-region. Spilomelinae described over 3,800 species in the world, but Species diversity of Spiloemlinae moths were recorded only seven species in Laos by Shubhalaxmi (2011), Mally (2015) and Park et al. (2017). In this study, we provided seven species of illustrations and basic data on Laotian moth research.

This paper proposes a dynamic magnetic field emulator (DMFE), which can electrically emulate information for the magnetic stripes of most widely used credit cards. Payment transactions with most common credit cards are performed by reading the card’s information, encoded in magnetic stripes, using the reader head of a point-of-sale (POS) system. A stripe-type permanent magnet is attached to the back side of the credit card, and information for payments or value-added service is reorganized by exposing it to strong magnetic field. The process of data recording and retrieving as stated above has been pointed out as a major cause of illegal credit card use, because the information on the magnetic stripe is always exposed, and is thus vulnerable to forgery or alteration. A dynamic magnetic field emulator displays card information only when necessary by using the principle of solenoidal magnets. The DMFE proposed in this paper can prevent fraudulent use if it is operated with a device, like a smart phone, or a separate user-authentication procedure. In addition, because it is possible to display various information as needed, it can be utilized for a smart multi-card application, in which information for multiple cards is stored in one card, and can be selected and used as needed. This paper introduces the necessity of the DMFE and its manufacturing principles. As a result, this study will be helpful for making various application cases in payment, which is a core area of the Fintech (a newly-coined word of finance and technology) industry.

Pyraustinae and Spliomelinae are one of the largest subfamily in the family Crambidae, They are reported more than5,000 species in the world. The majority of them is distributed in tropical regions, also some species discovered intosubtropical and warm temperate areas. Laos has a tropical climate because it is located in Southeast Asia. but Laos properlyhas not studied moths diversity by the present.In the present study, we provided a checklist of the subfamily Pyraustinae and Spilomelinae from Laos, including adultphotographs, distributions.

The in vitro culture of Toxoplasma gondii was evaluated using a JNUCK cell strain that was independently developed by our research team. The sensitivity of the JNUCK strain was compared with those of MDCK and vero cell strains, which were previously shown to be sensitive to T. gondii. Morphological observation and 3H-uracil absorption tests showed that JNUCK cell strain has the highest sensitivity, while the MDCK and vero cell strains showed lower sensitivities. The optimal culture conditions using the JNUCK cell strain were determined by inoculating T. gondii at multiplicity of infection (MOI) 1, MOI 5, and MOI 25 and the numbers of T. gondii were measured 24, 48, and 72 hours after inoculation. The optimal medium composition was determined by adding different concentrations of FBS to DMEM medium for inoculation at MOI 5, and then calculating the numbers of tachyzoites inside the cells and in the medium. The numbers of tachyzoites inside the cell were highest for 10% FBS, while the numbers of tachyzoites in the medium peaked after addition of 30% FBS. These studies confirmed that the optimal culture condition of T. gondii using the JNUCK cell strain was achieved by inoculation at MOI 5, using medium containing 20% FBS and culturing for 72 hours.

Vulpes zerda is a fox that inhabits the desert regions of North Africa and Asia, whereas Vulpes pallida is a fox that inhabits the savannah zones of North Africa and the Sahara desert. Vulpes zerda, which is on the “Red List of Threatened Species” designated by the International Union for Conservation of Nature and Natural Resources (IUCN), belongs to the “Appendix II” group drawn up by the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and hence its cross-border trade is prohibited. In contrast, Vulpes pallida is classified as being of “Least concern” (LC) by IUCN. However, distinguishing between Vulpes pallida and Vulpes zerda by shape alone is difficult. This study attempted to differentiate between the two species by examining the chromosomes of Vulpe szerda and Vulpes pallida that were raised in Korea. According to the examination, two of eight foxes believed to be Vulpes zerda were Vulpes pallida and one of six foxes believed to be Vulpes pallida was actually Vulpes zerda. Considering the ambiguity of making a formal distinction between Vulpes zerda and Vulpes pallida, a more scientific approach to differentiation will be required.

As film products are increasingly used in a wide range of areas, from producing traditional flexible packaging to high-tech electronic products, a higher level of quality is demanded. Most film products are made in the form of rolled finished goods, therefore, various quality issues related to their shape characteristics must be addressed. The thickness of the film products is one of the most common and important critical-to-quality attributes (CTQs). Particularly, the degree of thickness uniformity is more important than other thickness parameters, because it will be potential causes of many secondary thickness-related quality problems, such as wrinkles or faulty windings. To control the degree of thickness uniformity, the fixed bending region is oneof the most important CTQs to manage. Fixed bending regions are special points in the transverse direction of a rolled product with consistent minute variations of the thickness gap. This paper describes the measurement and analysis of thickness uniformity data, which were performed in a real manufacturing field of biaxial oriented polypropylene (BOPP) film. In previous researches, quality function deployment (QFD) or fault tree analysis were used to find the most critical process attributes out to controlthe CTQ of thickness uniformity. Whereas, this paper uses traditional control charts to find the most critical process attributes out in this problem. In addition, the selection of one of the major critical process attributes (CTPs) that is expected to affect the CTQ of thickness uniformity is also described. The selected critical-to-process attributes are the controlled temperatures along the transverse direction. A dramatic improvement in thickness uniformity was observed when the selected CTPs were controlled.

As film products are more frequently used from producing traditional flexible packing products to high-tech electronic products, requested higher level of quality. Most film products are made in the shape of roll-type finished goods, so various quality problems are addressed related with their characteristics of shape. Thickness of film products is one of the most common and important quality problems. Particularly the Degree of thick smoothness is more important than other thickness issues, because it causes many secondary issues of thickness-related quality problems like wrinkles or faulty windings. Thick smoothness must be controlled in both horizontal and vertical direction. In this paper, HOQ (house of quality) was built to interpret VOC (voice of customers) to CTQs (critical to quality). To decide priorities of VOC and CTQs, both techniques are applied. One is AHP (analytic hierarchy process) with pairwise comparison. The other is an absolute weight calculation method with level-up rate. From the result of HOQ, it is certain that the thick smoothness is the most important CTQ in film manufacturing industry. Finally, this paper presents how to monitor and improve repetitive coincidence of microscopic deviation of thickness in some special vertical points.
