In this study, whiteleg shrimp (Penaeus vannamei) imported from Vietnam were collected from South Korean markets, and examined for 2 viruses: infectious hypodermal and hematopoietic necrosis virus (IHHNV, recently classified as decapod penstyldensovirus-1), and white spot syndrome virus (WSSV). Among 58 samples, we detected IHHNV in 23 samples and WSSV in 2 samples, using polymerase chain reaction and sequencing analyses. This is the first report of IHHNV and WSSV detection in imported shrimp, suggesting that greater awareness and stricter quarantine policies regarding viruses infecting shrimp imported to South Korea are required.

There are many differences in the present conditions of Oriental Health care and the study of Sasang Constitution Medicine between in North Korea and South Korea. 1. The government of South Korea hasn't supported Oriental Medicine with administrative plans but that of North Korea has supported it positively and made efforts to systematize it. 2. The government of North Korea has considered Oriental Medicine and Western Medicine as mutual supplementary relationship and tried to harmonize them, invested human being and material resources in developing affirmative aspects of Oriental Medicine. That efforts of them made O.M of North Korea developed. 3. In North Korea, they has studied about the principles of O.M. generally in a laboratory. 4. In North Korea, only herbs nation warrant and satisfy standards and fixed orders can be circulated. 5. Because the Sasang Constitution Medicine is opposite to aspect of Materialism, they exclude that from Korean Medicine subjects. They only use them for clinical remedy. But recently, they concern Sasang Constitution Medicine more and more. So also in South Korea, we need to strengthen the political support of the government and the research of laboratory.

Objective : This study was conducted to examine the relationship between the annual changes of suicide methods and suicide rates in South Korea. We compared the suicide methods in South Korea with those in six other OECD countries, Japan, Finland, France, United States, Canada and Australia. Methods : Data of suicide rates and methods since the year 2000 were obtained from the official electronic mortality data published by the seven countries and from the World Health Organization [WHO] mortality database. We compared the correlation between suicide methods and suicidal rates in South Korea using Spearman's correlation test. Results : The proportion of hanging steadily increased, whereas self-poisoning steadily decreased from 2000 to 2011. The increased use of hanging was associated with the increase of suicide rates in South Korea. The preference for jumping as a suicide method in South Korea can be notably compared to that of other countries. Conclusion : Preference use of lethal methods, such as hanging, may play a great role in the increase of suicide rates in South Korea. The limitation of physical and cognitive access to lethal methods can be an effective suicide prevention strategy.

Background : Terminology is a good index of reflections in conceptional imaginations, trends and technological advances in the field of their own. The purpose of this study is to compare the similarity and difference of terms in periodontology to evaluate the communicability between South and North Korea. These result may be particularly helpful for making glossary, academic communication and social unity at the time of reunion. Methods : This study was carried out by searching northern periodontology terminologies used in literatures published in North Korea and comparing those terms with the southern terms. The standard northen terms were not able to be distinguished, so the terms used frequently were chosen as the standard northern terms. Results : The South and North both use terms that stem from Chinese characters, but this tendency is stronger in the South. The main differences between the South and North are due to the North Korea's effort in converting terms into the native languages. There are also some differences in inscription of foreign language, spelling and spacing, and so on. Conclusion : The terminology using in South and North Korea in the field of periodontology is somewhat different but both side can be capable of communication. Now the basic efforts in both parts must be taken, such as establishing new terms, in order to relieve these differences.

Oral submucous fibrosis (OSF) is a premalignant condition characterized by juxtaepithelial fibrosis of the oral cavity. The clinical manifestations include burning sensation to spicy food, blanched oral mucosa with palpable fibrous bands, trismus, depapillation of tongue, and dry mouth. As OSF is predominantly seen in people of the Indian subcontinent, cases of this disease have been rarely reported in South Korea. We present a case of OSF in a Sri Lankan man living in South Korea and emphasize the importance of enhancing knowledge of this disease while the number of immigrants is increasing.

The government of South Korea and its medical personnel must make a way by which health professionals who have escaped from the Democratic People's Republic of Korea (DPRK) can play a positive and practical role in unification and south-north medical unification while south-north authority talks on DPRK public health and medicine manpower development are not going smoothly. Medical personnel escaped from the DPRK have to be recruited for the interviewer of the national examination, to improve the accuracy of national examination interviews. For those medical professionals who have escaped from the DPRK with 6 years' medical college education, but failed the interview on the national examination, we propose here a course of 3.6 months for them to have a right to apply the Korean Medical Licensing Examinations (KMLE). We also propose that medical professionals who have escaped from the DPRK who have graduated from a 6-year medical college in the DPRK and who are medical doctors over the fifth grade or with more than 6 years of experience can be qualified as unification medical doctors and be exempted from the KMLE, getting the right to go directly into an internship and residency. They should be permitted to work in manpower development projects for the health professions. They should also be given opportunities such as to become psychiatrists who treat the mental illness of persons escaped from the DPRK and people from North Korea after unification. Medical students in South Korea should earn college credits on the topic of medical unification and not only students, but all South Korean medical personnel, should prepare for north-south medical unification with an open mind. A way for each medical college to participate in DPRK manpower development for the health professions through a memorandum of understanding between the medical colleges of the south and north.

Chlamydia possesses a conserved 7.5 kb plasmid that is known to play an important role in chlamydial pathogenesis, since some chlamydial organisms lacking the plasmid are attenuated. The chlamydial transformation system developed recently required the use of plasmid-free organisms. Thus, the generation and identification of plasmid-free organisms represent a key step in understanding chlamydial pathogenic mechanisms. A tricolor immunofluorescence assay for simultaneously detecting the plasmid-encoded Pgp3 and whole organisms plus DNA staining was used to screen C. muridarum organisms selected with novobiocin. PCR was used to detect the plasmid genes. Next-generation sequencing was then used to sequence the genomes of plasmid-free C. muridarum candidates and the parental C. muridarum Nigg strain. We generated five independent clones of plasmid-free C. muridarum organisms by using a combination of novobiocin treatment and screening plaque-purified clones with anti-Pgp3 antibody. The clones were confirmed to lack plasmid genes by PCR analysis. No GlgA protein or glycogen accumulation was detected in cells infected with the plasmid-free clones. More importantly, whole-genome sequencing characterization of the plasmid-free C. muridarum organism and the parental C. muridarum Nigg strain revealed no additional mutations other than loss of the plasmid in the plasmid-free C. muridarum organism. Thus, the Pgp3-based immunofluorescence assay has allowed us to identify authentic plasmid-free organisms that are useful for further investigating chlamydial pathogenic mechanisms.

Purpose: Breast cancer is the most commonly occurring cancer among women worldwide, and therefore, improved approaches for its early detection are urgently needed. As microRNAs (miRNAs) are increasingly recognized as critical regulators in tumorigenesis and possess excellent stability in plasma, this study focused on using miRNAs to develop a method for identifying noninvasive biomarkers. Methods: To discover critical candidates, differential expression analysis was performed on tissue-originated miRNA profiles of 409 early breast cancer patients and 87 healthy controls from The Cancer Genome Atlas database. We selected candidates from the differentially expressed miRNAs and then evaluated every possible molecular signature formed by the candidates. The best signature was validated in independent serum samples from 113 early breast cancer patients and 47 healthy controls using reverse transcription quantitative real-time polymerase chain reaction. Results: The miRNA candidates in our method were revealed to be associated with breast cancer according to previous studies and showed potential as useful biomarkers. When validated in independent serum samples, the area under curve of the final miRNA signature (miR-21-3p, miR-21-5p, and miR-99a-5p) was 0.895. Diagnostic sensitivity and specificity were 97.9% and 73.5%, respectively. Conclusion: The present study established a novel and effective method to identify biomarkers for early breast cancer. And the method, is also suitable for other cancer types. Furthermore, a combination of three miRNAs was identified as a prospective biomarker for breast cancer early detection.

This study describes the first record of Bourgelatia diducta (Nematoda: Chabertiidae) from wild boars in the Republic of Korea (=South Korea). Gastrointestinal tracts of 87 Korean wild boars (Sus scrofa coreanus) hunted in mountains in the south-western part of South Korea between 2009 and 2012 were examined for their visceral helminths. B. diducta, as identified by morphological characteristics of the head and tail, were recovered from the large intestine of 47 (54%) wild boars. The average length of adult female worms was $11.3{\pm}0.872$ mm and the thickest part of the body measured $0.54{\pm}0.04$ mm in maximum width, while those of males were $9.8{\pm}0.72$ and $0.45{\pm}0.03$ mm, respectively. The characteristic J-shaped type II ovejector was observed in females, and the type II dorsal ray with 2 rami on each side of the median fissure was uniquely seen in males. The buccal capsule was small, relatively thin-walled, cylindrical, very short, and ring-shaped. The externodorsal ray arose from a common stem with the dorsal ray. The cervical groove was absent. The anterior extremity was equipped with 20-22 external corona radiata, 4 cephalic papillae and 2 lateral amphids around the mouth. The eggs were $66.0{\times}38.9{\mu}m$ in average size. By the present study, B. diducta (Nematoda: Chabertiidae) is recorded for the first time in South Korea. Additionally, morphological characteristics and identification keys provided in the present study will be helpful in the faunistic or taxonomic studies for strongylid nematodes related.
