Background: A comprehensive history taking at the first visit could be an important start of treatment. This study investigated the current status of the initial history taking for dental patients in S area, and the implementation and importance of the initial history taking process. Based on this, we intend to provide basic data for the development of organized and standardized questionnaires in dental clinics. Methods: In April 2019, 303 dental clinics in S area were targeted and special dental clinics (orthodontics, children, and disabled) were excluded. The questionnaire consisted of 29 items, including general characteristics, systemic disease history, dental history, oral health behaviors, and the data were obtained through self-administered questionnaire. Results: Initial history taking was mostly implemented using oral and questionnaire at the time of the first visit. Systemic disease history, dental history, and oral health behaviors differed in the work experience of the dental clinic staff. As a result of analyzing the importance according to implementation, there were significant differences in all questions except drug-related items. The importance of the questionnaire was highly recognized, but the reason it was not actually implemented was because of existing the questionnaire in the clinic and lack of time. Conclusion: Considering that the initial history taking implementation rate showed low, it is necessary to develop standardize a practical questionnaire and interview skills for dental clinics in the future. In addition, training programs should be provided to dental staff that can recognize the importance of initial history taking questionnaires and contribute to active implementation.

The purpose of this study was to provide a master plan for the establishment of a Korean National Museum of Natural History. The origin and development of the natural history and the natural history museum were surveyed by visiting not only Korean natural history museums but also foreign ones from 1987 to 2009. Based on the obtained information, the qualitative and quantitative status of Korean natural history museums was comparatively analyzed in terms of globalization. Results indicated that Korean natural history museums ranked more than 100th in the world, and the research, management, and publications were situated in a rudimentary stage. Particularly, the number of researchers within the area was too small, and the research environment was poor in its function and resources. In addition, the specialists on exhibition and education of the museums were too few to publish the research products and academic journal articles. For that matter, a strategy as the research-specimen management-publication-exhibition-education functions should be in place to operate before the construction of National Museum of Natural History begins.

This study was done to provide basic data on prevention of breast cancer by identifying and analyzing risk factors for breast cancer in Korean women. The data were collected from three hospitals. The data from Jan. 1995 to Dec. 1997 was based on the patient recordings and personal contacts if possible. Data from 1998 to 1999 was collected from 280 inpatients and outpatients diagnosed as breast cancer. From this data, information about the risk factors of breast cancer could be acquired. The factors are scaled according to the degree of risk. Menstrual history, obstetrical history, family history. lactation period, life style were given 5 point, and body mass index was given 4 point. Using one-way ANOVA. the most important risk factors were identified and analyzed by multiple regression. The conclusion of this study are as follows : General factors which would show an effect on the results of the multiple regression included risk factors such as menstrual history, obstetrical history, lactation period, family history, and life style factors including mortal state, monthly income, educational level, job and age. Family history(R=0.481) was found to be the highest risk factor(23.1%) affecting breast cancer risk. The next factors were dying hair(R=0.603), drinking(R=0.846), body mass index(R=0.885), smoking(R=0.916), age of menopause(R=0.937), pregnancy age of first full-term(R=0.957), eating vegetable(R=0.980) and the number of full term pregnancies in that order. The sum total(R=0.986) of all the above factors accounted for 97.3% of the risk of breast cancer for Korean women. In conclusion, it was found that family history and dyeing hair were the highest risk factors for breast cancer. It is recommended that those with a family history of breast cancer should have regular breast examinations, and those who often dye their hair should reconsider this practice.

It was not until the early twentieth century that statistics emerged as an independent academic discipline. The developments of statistical theory and methods would not have been possible without heated controversies among founding fathers. One of them, controversy on the statistical test between R. A. Fisher and J. Neyman, E. S. Pearson had been very fierce and long-lasting. On the other hand it was in the early twentieth century that psychologists began to utilize statistical test which was a hybrid of tests developed by Fisher and Neyman-Pearson. By considering the history of fields such as psychology, we can see distinctive characteristics specific to the history of statistics.

It is intended to retrieve the time history of displacement from measured acceleration signal. In this study, the word retrieving means reconstructing the time history of original displacement signal from already measured acceleration signal not just extracting various information using relevant signal processing techniques. Unlike extracting required information from the signal, there are not many options to apply to retrieve the time history of displacement signal, once the acceleration signal is measured and recorded with given sampling rate. There are two methods, in general, to convert measured acceleration signal into displacement signal. One is directly integrating the acceleration signal in time domain. The other is dividing the Fourier transformed acceleration signal by the scale factor of - $\omega$$^2$and taking the inverse Fourier transform of it. It turned out both the methods produced a significant amount of errors depending on the sampling resolution in time and frequency domain when digitizing the acceleration signals. A simple and effective way to convert the time history of acceleration signal into the time history of displacement signal without significant errors is studied here with the analysis on the errors involved in the conversion process.

The purpose of this study was to explore the various perspectives to read micro-history of Korean housing after the period of Opening the Port for foreigners. This study were designed to adapt original theory for exploring the unique housing perspectives without using strict basic assumption which were already developed in the area of sociology, history, anthropology and philosophy. Research method applied was literature review. Each perspective might give useful insight to read the micro-history of Korean housing on the way of change after the Period of Opening the Port in Korea. Adapted perspectives to housing history were critical theory perspective, microsociological perspective, everyday life perspective(phenomenology tradition, symbolic interaction tradition, Marxist tradition), discourse perspective, exchange theory perspective, conflict theory perspective, and life course perspective. Conclusively, each perspective must be adapted multi-supportively to read the housing phenomena, because housing change derived from complex causes and factors. The fruit of this study was to ensure the adaptable viewpoint to housing were useful to read the micro-history of housing change.

Balhae was an ancient Korean kingdom that existed almost 1,300 years ago. It was a dynamic time in the Korean history when the national strength was building up in terms of politics, economy and culture, thereby called as "Haedongseongguk, the powerhouse in the East". Balhae had dominated parts of Manchuria and the northern part of the Korean peninsula between the late 7th century and the 10th century, occupying the center stage of the northern Korean history. It serves as a window to the East Asia in the present as well as in the past. Yet, due to its geography spanning from the North Korea to Kilin Province of China to part of Heilongjiang Province and to the Littoral Province of Siberia, Balhae has been the center of historical disputes among neighboring countries that insist it is part of each of their own history. China argues that it was a prefecture of the Tang Dynasty, established by the Mohe, not a successor to Goguryeo, which is a China-oriented viewpoint of history. In addition, Russia recognizes Balhae as their first-ever medieval feudal state since the Littoral Province is now under their sovereignty. Therefore, the restoration of Balhae history is in line with the veritable establishment of the ancient Korean history. For this, it is necessary to embrace inter-disciplinary achievements and to continue efforts to adopt them rather than to blame the shortage of historical documents and the difficulty of the excavation of relics. If fashion is "a visual symbol" of our society, beauty culture serve as a mirror to reflect our civilization and culture directly or indirectly. Still, it is not easy to draw similarities by analyzing and comparing the attributes of various cultures and civilizations party because the essence of culture lies in diversity. Nevertheless, it is believed that cultural liaison as well as geographical liaison can be a medium to compensate for the limits of the foreign exchange history of Southeast Asia in proving the relationship between Goguryeo and Balhae, by examining and speculating beauty culture that reflect their period. It was confirmed by various documents regarding Goguryeo out of relics, historical sites and documents. Mural paintings showed how the people of Balhae wore and accessorized themselves. They also allowed us to speculate their way of living. As the contemporary historians can assert that Balhae is part of the Korean history thanks to the realism scholars in the late Joseon Dynasty, who rediscovered the Balhae history and conducted practical researches, it is expected that researchers who study beauty culture contribute to completing the restoration of the Balhae history by thoroughly examining our history, costume and beauty culture.
