Over the past few decades, changes in patterns of behavior (e.g., diet, smoking, alcohol consumption, and physical activity) have led to major changes in health status, characterized by increases in obesity, Type II diabetes mellitus, cardiovascular disease, and some cancers. This epidemiologic transition is largely the result of rapid increases in immigration to developed countries and rural-urban migration within developing countries, which is usually accompanied by environmental and lifestyle changes. In particular, adoption of “Western” dietary patterns, which tend to be high in fat and low in fruits and vegetables, is of concern since diet is a potent contributor to chronic disease risk. However, until recently, the process by which immigrants and rural-urban migrants adopt the dietary practices predominant in their new environments, known as dietary acculturation, has received very little research attention. Dietary acculturation is multidimensional, dynamic, and complex, and varies considerably depending on a variety of personal, cultural, and environmental characteristics. Therefore, to intervene successfully on the negative aspects of dietary acculturation, it is important to understand the process and identify factors that predispose and enable it to occur. The purpose of this article is to provide a practical model for understanding and investigating the effect of dietary acculturation on food and nutrient intake. Thus, this report 1) gives an overview of acculturation, 2) defines dietary acculturation and presents a model for how it occurs, 3) discusses measurement issues around dietary acculturation,4) reviews the literature on dietary acculturation in Korean Americans; 4) suggests a paradigm for acculturation research; and 5) offers some recommendations for future research in this area.

The construction of government-sponsored housing in Korea began in the early 1950s. Beyond fulfilling the housing shortage after the Korean War, it also impacted the development of housing in Korea. The aim of this study is to explore the construction and supply of government-sponsored housing and to discuss the positive and negative influences on the modern housing in Korea. In order to achieve the objectives, the pictures and floor plans, newspaper articles and the KNHC publications, which led the public housing supply from 1950 to 1960, were examined. Results indicate as follows: First, government-sponsored housing industrialized the housing production, which satisfied the volume need. The simplified floor plan and exterior, along with the western characteristics, created a new urban landscape. Second, the distinct characteristics of Korean housing were established. By emphasizing development and financial practicality, large scale housing complexes were built with simplified, characterless, and mechanical exteriors in a disconnected territory with neighbor district. Third, government-sponsored housing became the major accelerator to westernize the Korean housing culture. In conclusion, the principles of functionalism of government-sponsored housing have become the fundamental root of Korean housing since the war.

By combining in situ hybridization (ISH) and immunocytochemistry (IC), microscopic topological localization of mRNAs and proteins can be determined. Although this technique can be applied to a variety of tissues, it is particularly important for use on neuronal cells which are morphologically complex and in which specific mRNAs and proteins are located in distinct subcellular domains such as dendrites and dendritic spines. One common technical problem for combined ISH and IC is that the signal for immunocytochemical localization of proteins often becomes much weaker after conducting ISH. In this manuscript, we report a simplified but robust protocol that allows immunocytochemical localization of proteins after ISH. In this protocol, we fix cultured cortical or hippocampal neurons with 4% paraformaldehyde (PFA), rinse briefly in PBS, and then further fix the cells with $-20^{\circ}C$ methanol. Our method has several major advantages over previously described ones in that (1) it is simple, as it is just consecutive routine fixation procedures, (2) it does not require any special alteration to the fixation procedures such as changes in salt concentration, and (3) it can be used with antibodies that are compatible with either methanol (MeOH-) or PFA-fixed target proteins. To our best knowledge, we are the first to employ this fixation method for fluorescence ISH + IC.

Floating debris provides substrates for dispersal of organisms by ocean currents, including algae that thrive on plastics. The 2011 earthquake and tsunami in Tohuku, Japan resulted in large amounts of debris carried by the North Pacific Current to North America from 2012 to 2016. In 2015-2016, the plastics in the debris bore a complex biota including pink algal crusts. One sample (JAW4874) was isolated into culture and a three-gene phylogeny (psbA, rbcL, and SSU) indicated it was an unknown member of the red algal class Stylonematophyceae. It is a small pulvinate crust of radiating, branched, uniseriate filaments with cells containing a single centrally suspended nucleus and a single purple to pink, multi-lobed, parietal plastid lacking a pyrenoid. Cells can be released as spores that attach and germinate to form straight filaments by transverse apical cell divisions, and subsequent longitudinal and oblique intercalary divisions produce masses of lateral branches. This alga is named Tsunamia transpacifica gen. nov. et sp. nov. Sequencing of additional samples of red algal crusts on plastics revealed another undescribed Stylonematophycean species, suggesting that these algae may be frequent on drift oceanic plastics.

This study investigated the comparative advantages of the Bangladeshi and Vietnamese apparel industries using Global Value Chain (GVC) framework. In this study, the GVC framework was expanded to include social and environmental sustainability issues. Secondary data, for the 2012 - 2013 period, were collected and analyzed for each component of the apparel GVC. The findings indicated that while both countries have unique comparative advantages, Vietnam clearly emerged as a leader on many GVC components. Bangladesh's comparative advantage lies in lower wages, producing high volume orders, and lean manufacturing. In spite of Vietnam's higher labor costs, it has comparative advantages in higher productivity, skilled and trained workers, manufacturing of intricate styles of high quality, agility and flexible manufacturing, more developed infrastructure and logistic services as well as greater social and environmental compliances. This study contributes towards insight into best sourcing fit for fashion brand business models. Based on the findings, fashion driven companies offering more complex styles at a faster rate will benefit from choosing Vietnam. In contrast, Bangladesh might be a better choice for high volume driven companies that offer basic apparel and better value for their consumers. From theoretical perspective, the research makes an important contribution by expanding the GVC framework.

The purpose of this research was to investigate the influential factors to wear or not to wear \"Hanbok\" in Korean society. Twenty six individuals who wear Hanbok relatively often, and twenty seven individuals who dont were purposively sampled and interviewed for the study by structured depth-interview method. A domain analysis, a method of qualitative study, was employed to find out the influential factors from the results of the depth-intervews. From the analysis, fifteen encouraging or discouraging factors to wear Hanbok emerged and were categorized into five domains, which included \"interpersonal relationship\", \"life-style\", \"image\", \"practicality\" and \"decorative function\". The personal involvement in traditional culture, tradition-oriented family background, good images related to Hanbok, and affordable life-style appeared to be encouraging factors to wear Hanbok. Meanwhile, social norm and role-expectation adjusted to westernized criteria, unaffordable life-style, ill practicality of Hanbok and negative cues associated with Hanbok were the factors influencing people to turn away from Hanbok. The study also revealed complex interactions between these factors explaining individuals choice of wearing or not wearing Hanbok in industrialized modern society of Korea. Some suggestions to promote wearing Hanbok were made based oh the results of this study.wearing Hanbok were made based oh the results of this study.

Traditionally, genetic variability is generated by an extensive crossing program, which is complemented by strict selection to identify useful new recombinants. Plant biotechnology offers many opportunities for breeders to solve certain breeding problems at the molecular level. The tissue culture methodology and the genetic modification of economically important monocotyledons have undergone a revolution in the last decade. As the production of transgenic plants is a complex procedure, including the uptake of DNA molecules into the cells, the integration of foreign nucleotide sequences into the host genomic DNA and the expression of new genes in a controlled way, and as there are still many unsolved questions, further development is necessary. The methodology opens up the possibility of introducing novel genes that may induce resistance to diseases and abiotic stresses, allow the modification of dough quality and the dietetic quality of proteins, and increase the levels of micronutrients such as iron, zinc, and vitamins. In the present review, the authors would like to summarise the most important advances in wheat transformation.

Mycoplasma hyopneumoniae is among the most prevalent and important infectious agents associated with porcine respiratory disease complex. The airway dagame caused by M. hyopneumoniae adversely affect the pulmonary host defense mechanisms and may lead to secondary bacterial infections. Culture is considered to be the "gold standard" for diagnosis but this is a very slow and labor-intensive procedure. Isolation of M. hyopneumoniae is complicated by its fastidious nature and extremely slow growth. Thirty days of incubation may be necessary to detect the organism in primary broth cultures. The purposes of the study were (ⅰ) to develop nested PCR for the detection of M. hyopneumoniae for the detection of M. hyopneumoniae DNA in the formalin-fixed, paraffin-embedded lung tissues from experimentally and naturally infected pigs and (ⅱ) to compare the utility of nested PCR with in situ hybridization.

In the Sci-Fi movie, with future scene in its setting, how images are shown in the film is very important. Sci-Fi movie is supposed to be expressed In different way of its set design. This study suggests various types of expression in Sci-Fi movies. Sci-Fi movies construct the narrative upon the binary opposition of nature vs. culture, human vs. nonhuman. Sci-Fi movie is a contested terrain where conservative, liberal and radical ideologies are competing. While liberal Sci-Fi movies consider the opposition compatible, conservative texts show the paranoid towards science and nonhumans. And, Sci-Fi movies are expressed as utopian and dystopian. Utopian and dystopian elements are found in the history of architecture. Utopian element is often found in the religious architecture, and those buildings are geometric, orderly, and gorgeous. Dystopian element is often found in modern architecture, and those are asymmetric, distorted, and incompleted. Conservative movie, which developing of science is expressed negatively, retains both utopian and dystopian elements evenly. Liberal movie, such as Space Opera which science is expressed positively, is changed from futurist and mechanical type into more simple, geometric and orderly shrine type. Radical movie, which the boundary of human and science is expressed darkly, retains dark, complex, and incomplete dystopian expression elements.

Mancozeb (MCZ), a polymeric complex of zinr and manganese salts of ethylene bisthiocarbamate, is widely used in agriculture as fungicidel, insecticides, and herbicides. MCZ can be occupationally and environmentally exposed to human and has been reported to have detrimental effects on the reproductive system, but the toxicity of MCZ on immune responses has not been systematically investigated. We investigated the effects of MCZ exposure on the activities of murine splenocytes through evaluation of splenocytes cellularity and INF-$\gamma$ synthesis. Splenocytes were examned ex vivo from mice orally treated with various doEes of MCZ for 1 day (acute exposure, 2,100, 5,000, 10,000 mg/kg) or ior 5 consecutive days per week for 4 weeks (subacute exposure,250, 1,000, 1,500 mg/kg/day) fellowed by culture for 2 days in the presence of Con A or PHA plus IL-2. Splenocytes Iron naive mice were cultured with various concentration of MCZ (50, 500, 1,000 ng/ml) in the presence of Con A or PHA plus IL-2 for 2 days in vitro. IFN-$\gamma$ production was decreased with the in vitro exposure to all concentration of MCZ. The spleen cellularity and IFN -$\gamma$ production by splenocytes from MCZ -acutely and - subacutely exposured mice were decreased in comparision with that oi control group.
