Purpose: The purpose of this study was to examine the effect of school-based preventive education on smoking-related knowledge, attitude and practice of health behaviors among elementary school children at a rural province in Korea. Methods: The subjects were 134 among the 4th -6th graders (exp. = 67, control = 67) from two schools at J province. Education program was conducted in 5-sessions for experimental group. And study instrument for smoking-related knowledge was developed 2-point 15-items (a = .82), for attitude was 3-point 15-items (a = .79), and for practice of health behavior was also 3-point 30-items (a = .86). Data were collected by interview from May 28th to July 10th 2003 and analyzed with the frequency, percentage, x2-test and t-test using SPSS-PC program, Results: The group of having smoking experiences was 14.2% and 52.2% of the subject had smoking family members. The first motive of smoking was curiosity in 78.9% and 36.8% of them started smoking before the third grade. School-based preventive education of smoking were affirmatively effective in smoking-related knowledge (t = 4.14, p = .001), smoking-related attitude (t = 3.654, p = .001), practice of health behavior, on the other hand, was not changed significantly by the education. Conclusion: Based on these findings, the authors recommend that school-based smoking prevention education should be started from lower graders in regular curricular basis and health promotion program for primary school children should be emphasized to lead healthy behavior in collaboration with public and private health sectors in community.

Objective: Eggshell color is an important indicator of egg quality for consumers, especially for brown eggs. Various factors related to laying hens and their environment affect brown eggshell coloration. However, there have been no studies investigating hepatic functions of laying hens with variable intensity of brown eggshell color. Therefore, this study was aimed to identify potential factors affecting brown eggshell coloration in aged laying hens at the hepatic transcriptomic level. Methods: Five hundred 92-wk-old Hy-line Brown laying hens were screened to select laying hens with different intensity of brown eggshell color based on eggshell color fans. Based on eggshell color scores, hens with dark brown eggshells (DBE; eggshell color fan score = 14.8) and hens with light brown eggshells (LBE; eggshell color fan score = 9.7) were finally selected for the liver sampling. We performed RNA-seq analysis using the liver samples through the paired-end sequencing libraries. Differentially expressed genes (DEGs) profiling was carried out to identify their biological meaning by bioinformatics. Results: A total of 290 DEGs were identified with 196 being up-regulated and 94 being down-regulated in DBE groups as compared to LBE groups. The Kyoto encyclopedia of genes and genomes (KEGG) analysis revealed that these DEGs belong to several biological pathways including herpes simplex infection (toll-like receptor 3 [TLR3], cyclin-dependent kinase 1, etc.) and influenza A (TLR3, radical S-adenosyl methionine domain containing 2, myxovirus [influenza virus] resistance 1, etc.). Genes related to stress response (ceremide kinase like) and nutrient metabolism (phosphoenolpyruvate carboxy-kinase 1, methylmalonic aciduria [cobalamin deficiency] cblB type, glycine receptor alpha 2, solute carrier family 7 member 11, etc.) were also identified to be differentially expressed. Conclusion: The current results provide new insights regarding hepatic molecular functions related to different intensity of brown eggshell color in aged laying hens. These insights will contribute to future studies aiming to optimize brown eggshell coloration in aged laying hens.

Geron-technology contributing to successful "Aging in place" increases the quality of life for the elderly and decreases the social caring cost. This study aims to identify influencing factors on pre-implementation acceptance of geron-technology for the elderly residing in a community. Data for 129 participants were analyzed. Results indicated that location, physical function, lack of technical support by family members, and the high financial cost as a 28% power were identified as the influencing factors on pre-implementation acceptance of geron-technology. Therefore, in the development of health and welfare strategy, these influencing factors should be considered in order to archive 'aging in place' for the elderly.

Background: Angelica acutiloba Kitagawa belongs to the flowering plant family Apiaceae. Its young leaves are consumed as a vegetable, and its roots have medicinal properties. This study was conducted to analyze the seed germination characteristics of A. acutiloba according to its ripening stages. Methods and Results: The seeds were harvested from a research farm managed by the Department of Herbal Crop Research, Rural Development Administration in 2018 and were divided into six groups according to their specific gravities. In particular, we studied the effect of harvesting periods and umbel orders on seed characteristics. The results showed that the rates of germination, emergence, and early growth improved as the specific gravity of the seeds increased. In addition, the germination rates of the seeds harvested in mid July and early August were significantly higher than those harvested in the other seasons, and the seeds obtained from the first floret had the greatest mass and weight. Conclusions: In this study, we demonstrated that it is possible to improve the germination rate by appropriate selection of seeds and harvesting period both of which are closely related to seed maturity.

In Jesmyn Ward's 2017 novel, Sing, Unburied, Sing, Ward places herself within the modern African American literary tradition and lays out the unending "historical traumas" of blacks and cultural haunting in her narrative. She brings to the fore the story of a young black boy and demonstrates the difficulty of living while a black man in the American rural South. Living or dead, black males remain spectral as their frustrated black bodies are endlessly rejected and disembodied. It's through Ward's close attention to the notions of black masculinity and retrieval of (black) humanity that the black South is remembered, recuperated, and historicized. Shrewdly enough, Ward expands it further into the tradition of American literature. Instead of singularizing African American identity and its historical traumas, she renders them the part of American history and universalizing the single black story as the story of the American South. Filling in the gaps that Faulkner and other white writers have left in their novels, Ward writes stories about the unspeakable, the invisible, the excluded to deconstruct white narratives and rebuild the American history; and reasserts African roots and history, spirituality, black raciality and locality within the American tradition. I examine the symbolic significance of Jojo's claim of black masculinity within the socio-political contexts of contemporary America. I also look closely at Ward's portrayal of Jojo's black family genealogy on account of its traumatic experiences of incarceration in notorious Parchman Farm. Locating Jojo as the inspiration of linking the past and the present, the unburied and the living, I contend that Ward creates "home" for blacks in an atemporal oceanic space where the past and the present are able to meet simultaneously. I argue that the oceanic space is an alternative space of affect that functions against the space of white rationality.

This study is to explain the nature of transnational activities being involved in by Filipina intermarriage migrants in Korea by examining the institutional backgrounds of market, society and the state. The increasing number of Filipina intermarriage with Korean coincides with the advance of liberal market economy, which governs internal and bilateral interactions between and among the three institutions in both countries. While existing various reasons for engaging in intermarriage, a significant number of Filipina wives in Korea ventured into it with uncertain expectations that they might earn better lives and could support their families. Such hopes usually turn out in vain when they meet the real lives in Korea. It is mainly because their spouses in Korea would rather be those who left behind in the marriage market due to their lack of competitiveness. Filipina wives are also suffering from social isolation caused by language and other barriers such as family relations or rural life they might settle in. Their transnational activities usually tend to be their effort to breakthrough their unexpected condition of difficult lives in Korea. They usually make use of transnational sort of community activities to cultivate chances to engage in bread earning activity. Migrant's transnational activity has a great impact on sociocultural changes in the country of origin and of arrival. Transnational activity provides migrants with economic opportunities, and uplifts self-esteem as well. Intermarriage couples, especially with Southeast Asian wives, and their offsprings show a tendency of downward assimilation to Korean society. Korean state policy toward them should not simply apply undiscriminated assimilation theory, but take into account their possible strength of transnational identity with which they could find a means to integrate themselves successfully into the mainstream Korean society.

BACKGROUND: G protein-coupled receptors (GPCRs) are widely distributed in various organisms. Insect GPCRs shown as in vertebrate GPCRs are membrane receptors that coordinate or involve in various physiological processes such as learning/memory, development, locomotion, circadian rhythm, reproduction, etc. This study aimed to identify GPCRs expressed in fat body and compare the expression pattern of GPCRs in different temperature conditions. METHODS AND RESULTS: To identify GPCRs genes and compare their expression in different temperature conditions, total RNAs of fat body in Plutella xylostella larva were extracted and the transcriptomes have been analyzed via next generation sequencing method. From the fat body transcriptomes, genes that belong to GPCR Family A, B, and F were identified such as opsin, gonadotropin-releasing hormone receptor, neuropeptide F (NPF) receptor, muthuselah (Mth), diuretic hormone receptor, frizzled, etc. Under low temperature, expressions of GPCRs such as C-C chemokine receptor (CCR), opsin, prolactin-releasing peptide receptor, substance K receptor, Mth-like receptor, diuretic hormone receptor, frizzled and stan were higher than those at 25℃. They are involved in immunity, feeding, movement, odorant recognition, diuresis, and development. In contrast to the control (25℃), at high temperature GPCRs including CCR, gonadotropin-releasing hormone receptor, moody, NPF receptor, neuropeptide B1 receptor, frizzled and stan revealed higher expression whose biological functions are related to immunity, blood-brain barrier formation, feeding, learning, and reproduction. CONCLUSION: Transcriptome of fat body can provide understanding the pools of GPCRs. Identifications of fat body GPCRs may contribute to develop new targets for the control of insect pests.

This study explains the han-ok. in Gae-sung, which was antique and traditional city. In view of the fact that these were located in Gae-sung in North Korea hence direct investigate is not possible. Since there was no comprehensive study of Gaeseong han-ok, we have no choice but to rely on fragmentary records and memory of Gaeseong people. In accordance from the Japanese colonial era's surveys and sketches as well as how they were illustrated in the novel. Hark back to the peoples' thought of the han-ok years when they ran the survey in 1920s, the results were as follows: First, there are many houses so various classes in Mi-Mang. Jeon Cheo-man's house was a representative example of a rich family in Gae-sung, Jeon Je-seong(Jeon's 2^nd son)'s house was located in Si-jeon(government licensed-markets) near by the South gate. In particular, Jeon Yi-seong(Jeon's 3rd son)'s house was in rural areas. He managed on immense ginseng field and worker's houses. Hae-ju's house was a small house off the track. Second, the outer house is low and the main house is high and neat. Lastly, it was confirmed that it corresponded to sketches recorded by architects, such as neat housekeeping, long stones used for various purposes, invisible flat gates, the appearance of old and old houses and the composition of each room.

Photorhabdus is a bacterial symbiont of entomopathogenic nematodes of the genus Heterorhabditis in the family Heterorhabditidae. Photorhabdus is known to have nematicidal activity in addition to insecticidal activity. P. temperata isolated from Korean indigenous H. megidis Gwangju strain also produced high control efficacy against root-knot nematode Meloidogyne incognita and root-lesion nematode Pratylenchus penetrans. P. temperata has drawn interest as a potential bionematicide for the control of root-knot nematodes thereby. For the registration as an organic agricultural material, the toxicity of P. temperata was assessed by the acute toxicity test in carp (Cyprinus carpio) and acute oral and dermal toxicity tests in Sprague-Dawley rat (Rattus norvegicus) in compliance with the guidelines of the Rural Development Administration (RDA). In the acute toxicity test in fish, neither lethality nor abnormal responses of carp were observed. Body length and weight of carp and changes in DO concentrations and pH values were not significantly different between the treated group and the untreated control. In the acute oral and dermal toxicity tests, clinical signs, abnormal behavior, mortality, and pathological findings were not observed in all the experimental rats. The weight increment of all rats was normal. Acute toxicity results of P. temperata in fish and rats belonged to categories III, IV, and IV of RDA, respectively. Toxicity results of the present study indicated that P. temperata could be a safe and promising bionematicide against root-knot nematodes and root lesion nematode.

The concept of "public health care (public health and medical services)" as discussed in South Korea is used in an unclear sense, with a meaning unlike the terminology used worldwide. The terms "public health care (public health and medical services)" and "health care (health and medical services)" have the same legal definition in Korea. Globally, "public health care (public health and medical services)" refers to medical services provided to the public that are operated as publicly funded resources, but in Korea, this term is confined to limited medical services prescribed by the government. The following considerations regarding "public health care (public health and medical services)" in Korea are proposed: All medical services performed by the state, regional governments, health care institutions, or health care workers to protect and promote the health of the people should be clearly established as "public health care (public health and medical services)" by definition. The financial burden borne by the state through national health insurance should be increased to an appropriate level to clarify the state's responsibility. Improving public health is an urgent priority in Korea, and this goal can be achieved by improving regional public health through systematic relationships between the state and regional governments, establishing a Ministry of Health, and efficiently allocating public health doctors who are important for providing regional medical care in rural and remote areas. It will be possible to actively deal with infectious diseases at the national level through establishment of a Ministry of Disease Control and Prevention.
