In periodontics, much progress was made in the understanding of periodontal disease from 1960s to 1980s and in prevention and management of periodontal disease since the end of 1980s. This presentation will discuss about the prevalence of periodontal disease, treatment need, and provision of periodontal treatment in Korea, and how we could manage the periodontal disease efficiently in the future. According to an epidemiological study in Korea, periodontal disease(including gingivitis) was present in 82% of general population and periodontitis in 30-40% in adult population over 30y and juvenile periodontitis in 0.1% of adolescents. If we consider that at least 17% of these patients may have recurrent or refractory forms, there is obviously an abundance of disease that needs treatment, As a result of increase in life expectancy, senile population over 65 y will be increased from 6% in 1996 to 6.9% in 2000, and tooth retention rate and periodontal treatment need are expected to increase. Periodontists need all the help they can get from the general dentists to control periodontal disease. As for provision, postgraduate course in periodontics started in 1957 in Korea and produced over 700 specialized dentists in periodontics. One report indicated that the periodontists as well as general practitioners did periodontal therapy on only a few periodontal patients, because of specific control by current medical insurance system in Korea. Comprehensive periodontal examination is rarely done in local dental clinic. Therefore, enhancement of periodontal care in medical insurance system and education of simplified periodontal examination such as Periodontal Screening & Recording will make dentists diagnose and manage the management of adult patients is based on the recognition that there are multiple diseases, including gingivitis, chronic adlt periodontitis, and other more aggressive forms of periodontitis, and requires the earliest possible recognition of these three disease categories. In this presentation, we discuss practical approach using PSR to diagnose, manage and refer the patients, to facilitate the separation of the simple from the complex and the predictable from the unpredictable form of periodontal diseases and to integrate diagnostic and therapeutic techniques into private practice today.

Kings of the Joseon Dynasty composed poems exploring their thinking about the governance of the country or personal feelings. Kings Taejong (r. 1400-1418), Seongjong (r. 1469-1494), Yeongjo (r. 1724-1776), and other kings bestowed poems upon their officials and had them compose response poems using rhyming words. Such literary exchanges between sovereign and subject were called gaengjin. The vast body of surviving materials related to gaengjin includes chronological materials recording the words and acts of kings, Yeolseong oeje compiling writings by Joseon kings, the so-called gaengjin albums that kings specially produced to commemorate officials' composition of response poems, and literary collections by officials who took part in the composition of response poems. Gaengjin albums were produced immediately after the king's bestowal of a poem and the officials' composition of response poems. They provide diverse information about the background, content, and participants of literary exchanges. Many of these albums are held in the collection of the National Museum of Korea, Gyujanggak Archives at Seoul National University, and Jangseogak Archives of the Academy of Korean Studies. A majority of the extant gaengjin albums were produced during the reign of King Yeongjo. This paper analyzed chronological materials on the gaengjin literary exchanges that were officially conducted 200 times during the fifty-two-year reign of King Yeongjo. It also explored the drastic increase in gaengjin literary exchanges between 1769 (the forty-fifth year of the reign of King Yeongjo) and 1776 (the fifty-second year of the reign of King Yeongjo), the period corresponding to King Yeongjo's latter years. The paper introduced sixteen items (albums, books, hanging boards, and folding screens) related to the gaengjin literary exchanges held in the eighteenth and nineteenth centuries from the collection of the National Museum of Korea. Among them, it shed light on the production backgrounds, contents, and characteristics of the eight gaengjin albums produced during the reign of King Yeongjo. The materials related to the gaengjin literary exchanges created during the reign of King Yeongjo are valuable in that they improve the understanding of various aspects of the respective period, including joyous events of the state (or royal court), the administration of state affairs, and literary activities among the sovereign and subjects.

The purpose of this study was to investigate nutrients intake and health-related behaviors in elderly people residing in Gyeongsan-si, Gyeongbuk who have no problem in daily living. Information on general characteristics of the elderly, health-related behaviors and dietary habits were obtained by interview based on questionnare. Dietary nutrients intake data were obtained through the 24 recall method. The subject group of this study was composed of 113 males and 112 females, the average age being $73.1\pm6.06$ years old. In health related factors, $76.9\%$ of subjects exercised regularly. The rates of alcohol drinking and smoking showed to be $38.2\%\;and\;22.2\%$, respectively. There were many elderly with neuralgia, hypertension, and gastrointestinal disease, especially female were worse. Average heights of the subjects were lower than the standard established in the Korean Recommended Dietary Allowances, and average weights were similar to the standards. The mean BMI and WHR were 24.8 (male 23.7, female 25.7) and 0.92 (male 0.92, female 0.89), respectively. Most of the subjects had a regular meal pattern comsuming three meals a day, and many elderly, especially more than $79.5\%$ of female, prepared the meals for themselves. Mean daily energy intakes and RDA percentage of energy intakes of the male and female subjects were estimated as 1426.9kcal $(79.3\%)$ and 1381.3 kcal $(86.3\%)$, respectively. Mean daily intakes of nutrients were estimatied as 48.1g for protein, 411.3mg for calcium, 8.05mg for iron, 541.8 R.E. for vitamin A, 0.84mg for vitamin $B_1$, and 0.79mg for vitamin $B_2$. Most nutrients except protein, clacium, iron and vitamin $B_2$ were consumed over $75\%$ of the RDA. Female elderly showed significant lower intakes (p<0.05) for most of the nutrients except calcium, phosphorus and vitamin ethan the elderly male.
