  • Background: Cancer has important social consequences with cancer registration as the basis of moving towards prevention. The present study aimed to estimate the completeness of registration of the ten most common cancers in patients referred to selected hospitals in Shiraz, Iran by using capture-recapture method. Materials and Methods: This cross-sectional analytical study was performed in 2014 based on the data of 2009, on a total of 4,388 registered cancer patients. After cleaning data from two sources, using capture-recapture common findings were identified. Then, the percentage of the completeness of cancer registration was estimated using Chapman and Chao methods. Finally, the effects of demographic and treatment variables on the completeness of cancer registration were investigated. Results: The results showed that the percentages of completeness of cancer registration in the selected hospitals of Shiraz were 58.6% and 58.4%, and influenced by different variables. The age group between 40-49 years old was the highest represented and for the age group under 20 years old was the lowest for cancer registration. Breast cancer had the highest registration level and after that, thyroid and lung cancers, while colorectal cancer had the lowest registration level. Conclusions: According to the results, the number of cancers registered was very few and it seems that factors like inadequate knowledge of some doctors, imprecise diagnosis about the types of cancer, incorrectly filled out medical documents, and lack of sufficient accuracy in recording data on the computer cause errors and defects in cancer registration. This suggests a necessity to educate and teach doctors and other medical workers about the methods of documenting information related to cancer and also conduct additional measures to improve the cancer registration system.

  • MMORPG genre is based on the belief that all users in virtual world are equal. All users are able to obtain the corresponding wealth or status as they strive under the same resource, time. However, game bot is the main factor for harming this fair competition, causing benign gamers to feel a relative deprivation and deviate from the game. Game bots mainly form GFG(Gold Farming Group), which collects the goods in the game indiscriminately and adversely affects the economic system of the game. A general game bot detection algorithm is useful for detecting each bot, but it only covers few portions of GFG, not the whole, so it needs a wider range of detecting method. In this paper, we propose a method of detecting GFG based on items used in MMORPG genre. Several items that are mainly traded in the game were selected and the flows of those items were represented by a network. We Identified the characteristics of exchanging items of GFG bots and can identify the GFG's item trade network with real datasets from one of the popular online games.

  • Purpose: Chromosomal instability is a hallmark of gastric cancer (GC). It can be driven by single nucleotide variants (SNVs) in cell cycle genes. We investigated the associations between SNVs in candidate genes, PLK2, PLK3, and ATM, and GC risk and clinicopathological features. Materials and Methods: The genotyping study included 542 patients with GC and healthy controls. Generalized linear models were used for the risk and clinicopathological association analyses. Survival analysis was performed using the Kaplan-Meier method. The binding of candidate miRs was analyzed using a luciferase reporter assay. Results: The PLK2 Crs15009-Crs963615 haplotype was under-represented in the GC group compared to that in the control group (Pcorr=0.050). Male patients with the PLK2 rs963615 CT genotype had a lower risk of GC, whereas female patients had a higher risk (P=0.023; P=0.026). The PLK2 rs963615 CT genotype was associated with the absence of vascular invasion (P=0.012). The PLK3 rs12404160 AA genotype was associated with a higher risk of GC in the male population (P=0.015). The ATM Trs228589-Ars189037-Grs4585 haplotype was associated with a higher risk of GC (P<0.001). The ATM rs228589, rs189037, and rs4585 genotypes TA+AA, AG+GG, and TG+GG were associated with the absence of perineural invasion (P=0.034). In vitro analysis showed that the cancer-associated miR-23b-5p mimic specifically bound to the PLK2 rs15009 G allele (P=0.0097). Moreover, low miR-23b expression predicted longer 10-year survival (P=0.0066) in patients with GC. Conclusions: PLK2, PLK3, and ATM SNVs could potentially be helpful for the prediction of GC risk and clinicopathological features. PLK2 rs15009 affects the binding of miR-23b-5p. MiR-23b-5p expression status could serve as a prognostic marker for survival in patients with GC.

  • A variety of traditional costumes have been developed in Asia due to different natural and cultural environments and they are still worn by people in many areas. Traditional costumes in Asia have been formed under the influence of various ideologies, as well as technology and social structure. Three Asian religions(Buddhism, Hinduism and Islam), which have undeniably strong influence on traditional Asian cultures, have great effects on the styles of traditional costume in each region of Asia. The purpose of this study is to compare the characteristics and aesthetic values of traditional Asian costumes. To do this, the author used images of traditional costumes, which were taken in person by the author, in each region of Asia as reference. Unlike the traditional costumes in the West, which expose the body shape, traditional Asian costumes have nonstructural features in construction, form and wearing rules. They are also decorated with religious symbols and other ornaments, which is different from functional and non-decorative modern clothes. Each traditional Asian costume has unique characteristics. The costume under the influence of Buddhism shows the beauty of concealment that features trans-spatiality and abundant silhouette. On the other hand, the Hindu costume shows the beauty of symbolization represented by very colorful and complex ornaments, while costume in the Islam regions shows the beauty of restraint with clothes that wrap up the body in accordance with its strict religious discipline. Asian religions also represent philosophy, culture as well as an ethnic group. They have influenced entire Asian cultures including the arts, aesthetics and social structure and decided the style of costumes.

  • In this study, we analyzed queue length and sojourn time of discrete-time BMAP/G/1 queues under the workload control. Group customers (packets) with correlations arrive at the system following a discrete-time Markovian arrival process. The server starts busy period when the total service time of the arrived customers exceeds a predetermined workload threshold D and serves customers until the system is empty. From the analysis of workload and waiting time, distributions of queue length at the departure epoch and arbitrary time epoch and system sojourn time are derived. We also derived the mean value as a performance measure. Through numerical examples, we confirmed that we can obtain results represented by complex forms of equations, and we verified the validity of the theoretical values by comparing them with simulation results. From the results, we can obtain key performance measures of complex systems that operate similarly in various industrial fields and to analyze various optimization problems.

  • This study aimed to examine the vocational training system and related laws in the United States in the context of digitalization, the methods and scale of support for vocational training expenses, and the outcomes, with the goal of drawing applicable implications for domestic adoption and exploring policy measures. Vocational training in the United States is operated under the Workforce Innovation and Opportunity Act (WIOA) through either a Unified State Plan or a Combined State Plan, as formulated by each state. The WIOA vocational training program focuses on supplying and nurturing a workforce that meets the demands of employers. Notably, significant efforts by the U.S. government have been identified in addressing gaps in vocational training caused by digitalization. Providing educational programs and vocational training that can swiftly respond to technological changes is particularly commendable. Based on the U.S. model, Korea should also aim to move beyond mere skill acquisition to comprehensive competency development in its vocational training and encourage the participation of digitally disadvantaged groups.

  • The objective of this paper is to study the structural behavior of Composite Basement Wall (CBW) according to shear span-to-depth ratio through an experiment and predict the nonlinear behavior of CBW by using ADINA program widely has been being used for FE analysis. Especially, this study focuses on the part of CBW in which the Reinforced Concrete (RC) is under compression stress; At the region of CBW around each floor, RC part stresses by compressive force when lateral press by soil acts on the wall. The contact condition between RC wall and steel (H-Pile) including stud connector is main factor in the analysis since it governs overall structural behavior. In order to understand the structural behavior of CBW whose RC part is under compressive stress, an experimental work and finite element analysis were performed. Main parameter in the test is shear span-to-depth ratio. For simplicity in analysis, reinforcements were not modeled as a seperated element but idealized as smeared to concrete. All elements were modeled to have bi-linear relation of material properties. Three type of contact conditions such as All Generate Option (AGO), Same Element Group Option with Tie(SEGO-T) and Same Element Group Option with Not tie(SEGO-NT) were considered in the analysis. For each analysis, the stress flow and concentration were reviewed and analysis result was compared to test one. From the test result, CBW represented ductile behavior by contribution of steel member even if it had short shear span-to-depth ration which is close to "1". The global composite behavior of CBW whose concrete wall was under compressive stress could be predicted by using contact element in ADINA program. Especially, the modeling by using AGO and SEGO-T showed more close relation on comparing with test result.

  • For comparative analysis of the eubacterial community structure at 8 sampling sites throughout the Nak-Dong River, FISH (fluorescence in situ hybridization) method was employed. The total ratio of each determined eubacterial group such as ${\alpha}\;{\cdot}\;{\beta}\;{\cdot}\;{\gamma}-subclasses$proteobacteria and Cytophaga-Flavobacterium(CF) group to total counts(DAPI) at each site varied 9.3-42.5% with the highest value at uppermost part. And each ratio of determined eubacterial groups reached mostly under 10% except that of CF group (23%) at uppermost part. Furthermore, compared to lower part, upper part represented unexpectedly higher proportions of ${\gamma}-subclass$ proteobacteria comprised almost fast growing bacteria on degradable organics. Also the variations of ammonia-oxidizing bacteria ranged from $2.7{\times}10^4$ to $18.0{\times}10^4$ cells $mL^{-1}$ with the lowest value in lower part and the highest value in mid part whereas those of nitrite-oxidizing bacteria varied 5.2-7.7{\times}10^4$ cells $mL^{-1}$ without noticeable differences throughout the sites. Additionally, the ratio of nitrifying bacteria to total counts ranged from 1.0% to 13.6% with no differences between ammonia-oxidizing bacteria and nitrite-oxidizing bacteria. In conclusion, FISH method introduced in this study for monitoring, normally used for the quantitative analysis of bacteria, provided also good information on their environmental status in the Nak-Dong River.

  • The diversity of Southeast Asia can be also represented at the tremendous number of ethnic groups residing throughout its various regions even beyond national boundaries. What does it mean by the composite of numerous peoples? It has triggered a lot of problems in a nation or overall Southeast Asia. Among them, the most serious one seems to be ethnic conflicts having damaged national integration and caused political, economical, and social instability. In that respect, Karen people have been a minority group situated in the most chronic dispute in Myanmar. Since 1947 some of the Karen equipped with armed forces have been fighting against the military government currently ruling Myanmar. As the result, the refugees over 200,000 population had moved to the mountain camps located at neighboring Thailand, attracting a lot of attention throughout international societies. According to 1931 census by British colonial government, the Karen have the greatest numbers in population as minority and include 16 subgroups including Karenni(Kayah) and Pa-O seemingly excluded from its category in contemporary point of view. It means that Karen people should not be regarded as an ethnic group, and in fact do not show a homogeneous identity under the title of Karen. Given the situation, we need to reconsider the category of Karen. What does the Karen mean in a real sense? Previous studies on the Karen had been performed mainly by anthropologists or missionaries such as Marshall(1922), Hamilton (1976), Hanson Tadaw(1959), Smeaton(1920), Keyes(1979), Hayami (1992; 2004), etc. Most of them examined the Karen as a group and ignored the possibilities of representing the divergent identities vis-à-vis their subgroups. Therefore, they have focused on the myth to convert Karen people to Christianity, although the Christian Karens are less than 20% of total population. As a result, I argue that they would fail to define the real meaning of Karen. It has been caused us to recognize the Karen as a meaningless total entity to be accepted by all means. According to their arguments, the difference among Karen's subgroups is just dealt with the trivial matters that do not affect the ethnic boundary itself, still maintaining the ethnic identity as Karen. As we shall see on this thesis, this is never the case. My thesis aims at uncovering and scrutinizing the real meaning of the category of Karen. For the purpose of it, I will consider Karen people as a linguistic group from the beginning as shown in 1931 census. I argue that the Karen have been affected or exposed by various conditions or environments throughout the harsh history having happened on the areas of current Myanmar and Thailand, leading the vicissitudes of their ethnic identities.

  • Multiple regression analysis was used for the calculation of pKa values of 15 substituted benzaldoximes by using various types of descriptors as parameters. These descriptors are based on quantum mechanical treatments. They were derived by employing semi-empirical calculation represented by the PM3 model and an Abinitio method expressed by Hartree-Fock(HF) model performed at the 6-311 G(d, p) level of theory. The parameters tested for their ability to represent the variations observed in the experimental pKa(s) are atomic and structural properties including Muliken charges on the atoms of hydroxyl group and C=N bond, the angle $C_6-C_1-C_7$, and length of O-H bond. Molecular properties are also used like energies of HOMO and LUMO, hardness(${\eta}$), chemical potential(${\mu}$), total energy(TE), dipole of molecule(DM), and electrophilicity index(W). The relation between pKa values and each of these parameters of the studied compounds is investigated. Depending on these relations, two sets of parameters were constructed for comparison between the PM3 and HF methods. The results obtained favor the Abinitio method for such applications although both models proved to have high predictive power and have sufficient reliability to describe the effect of substituents on pKa values of benzaldoxime compounds under consideration which is clear from the values of correlation coefficient $R^2$ obtained and the consistency between the experimental and the calculated values.
