We investigate the provenance and the changes in the timekeeping system focusing on official records such as almanacs and textbooks published by the government after the solar calendar was introduced. We found that the solar calendar and the 12-hour clock time first appeared in 1884 during Joseon dynasty, at that time the solar calendar was used at the open port in Busan to facilitate the exchanges with Japan. The 12-hour clock time first appeared in the『Hansung Sunbo』published by the government in 1884. We also found that the Joseon dynasty also used 12 diǎnzhōng or 12 diǎn. In addition, the term of the ‘Sigan’ first appeared in the first official academic textbook in August 1895, and the chapter related to time contained the information about 12-hour clock time instead of the 12 Shi. In 1908, the meaning of the solar time, the equation of time, and the differences in longitude with the adoption of Korean Standard Time were introduced. Meanwhile, the 24-hour clock time was first introduced in Joseon and applied to railway times in 1907. The 1946 almanac, the first issue after liberation, used the 12-hour clock time which uses ‘Sango’, ‘Hao’ and the 24-hour clock time started to be used from the following year and is still used to this day. Finally, the 12-hour clock time, which was introduced around 1884, was enacted as Article 44 of the law in 1900 and was revised again in 1905 and 1908. In Korea, the terms related to the time in the current astronomical calendar system were newly defined around 1884, 1896, and 1908, and gradually standardized through the establishment of laws.

This is the study on the Hutchumcha of the traditional architecture in the Korea, China and Japan. The major conclusions are as followings: 1)Hutchumcha in Korea revealed the double 'S' letter in oblique and cloudy figure while that of China and Japan showed semicircle figure. 2) Korean Hutchumcha only had the function of fusing capital. 3)Korea had not outward projection called Chulmok, but China reached uh to four tiers, and Japan up to six. 4)While Korean Hutchumcha developed into the style of Ikkong, Chinese Hutchumcha distributed widely in royal and vernacular dwellings especially in the region of Fukien and Hangchow and Japanese Hutchumcha appeared often in later shrines and houses. 5)Hutchumcha such as Nanganpo only can be seen in Chinese and Japan traditional architectures.

Background: Single-nucleotide polymorphism (SNP) analysis is a powerful strategy for large-scale molecular population studies examining phylogenetic relationships among bacterial strains. Mycobacterial interspersed repetitive units-variable number of tandem repeats (MIRU-VNTR) can be easily digitized to share data among laboratories. This study applied SNP and MIRU-VNTR analyses for molecular strain typing of Mycobacterium tuberculosis isolates collected throughout Korea. Methods: We studied 102 clinical M. tuberculosis isolates, including 6 paired strains, collected from 11 university hospitals in Korea in 2008 and 2009. SNPs were detected using hairpin primer assays, and then, MIRU-VNTR analysis was performed. Results: Thirty-five SNPs contained polymorphisms that helped differentiate the 96 tested isolates. The isolates were classified into 15 clusters. The Beijing family strains were distributed within closely related clusters in the SNP dendrogram. For MIRU-VNTR analysis, the 96 isolates were divided into 12 groups. The discriminatory index in 8 of these groups (MIRU-10, -23, -26, and -31; ETR-A, -B, -C, and -F) was high (Hunter–Gaston diversity index > 0.6). Unlike the SNP method, MIRU-VNTR analysis did not identify any notable localizations of Beijing or non-Beijing family isolates in specific clusters. Conclusions: SNP and MIRU-VNTR analyses are surrogate molecular strain-typing methods for M. tuberculosis in Korea where Beijing family isolates are predominant

The Beijing family of Mycobacterium tuberculosis has been emerging in the world. However, there are few nationwide data of genotypic distribution in Korea. This study aimed to identify the genotypic diversity of clinical isolates of M. tuberculosis and to demonstrate the population of Beijing family in Korea. We collected 96 clinical M. tuberculosis isolates from 11 university hospitals nationwide in Korea from 2008 to 2009. We observed 24 clusters in IS6110-RFLP analysis and 19 patterns in spoligotyping. Seventy-five isolates were confirmed to be Beijing family. Two isolates of the K strain and 12 isolates of the K family strain were also found. We found that drug resistance phenotypes were more strongly associated with Beijing family than non-Beijing family (P=0.003). This study gives an overview of the distribution of genotypes of M. tuberculosis in Korea. These findings indicate that we have to pay more attention to control of M. tuberculosis strains associated with the Beijing family.

Objectives : The purpose of this research is to analyze the frequency, clinical characteristics of premenstrual syndrome, and the relationship between premenstrual syndrome and depression in middle school girls. Methods : Subjects of the research were 241 students recruited from 3 women's middle schools in Seoul, Korea. The questionnaires were composed of clinical characteristics of menstruation, Premenstrual Symptom Screening Tool, and Center for Epic Studies Depression Scale. Data were statistically analyzed by Chi-square, t-test, ANOVA, and Scheffe test. Results : The proportion of no/mild premenstrual syndrome was 83.4%, moderate to severe premenstrual syndrome was 12.9% and premenstrual dysphoric disorder was 3.7%. Premenstrual syndrome proportion was higher in severe menstruation pain group(χ2=11.956, p=.008) and depression group (χ2=50.85, p<.001). The mean of depression score was 11.61±9.09. Menstrual pain (F=4.59, p=.004) and premenstrual syndrome (F=68.81, p<.001) were found to be significant in depression. Conclusions : We identified that 16.6% of middle school girls suffered from premenstrual syndrome. We also analyzed that the clinical characteristics of menstruation pain and depression were related to premenstrual syndrome. And there was a relationship between depression and premenstrual syndrome. Accordingly, we can think of applying nursing interventions on menstruation pain and depression in middle school girls who are undergoing premenstrual syndrome.
