The northeastern part of Ogcheon zone which consisted mainly of Cambro-Ordovician arenaceous, argillaceous and calcareous formations and Carboni-Triassic arenaceous and argillaceous formations is delineated as the eastern mass of a thrust fault along Choongju-Moongyong-Cheongsan in the middle of the zone. The present study proposes a geotectonic line, Imgye-Samchog fault(see, figure 1) which divides the northeastern part into two blocks, Hambacksan block in the west and East coast block in the east. The igneous rocks in the Hambacksan block ranging from granite to gabbro are distributed in a symmetrical zones parallel to general direction of Ogcheon zone as follows (Fig. 2 and Table 2). Southeast igneous rock zone: it aligns Jurassic granites in its south and Precambrian leucocratic granites in its north. Central igneous rock zone: it aligns Cretaceous granites in its south and Jurassic granites, and some of diorite and gabbro in its north. Northwest igneous rock zone: aligns Jurassic granites in its south and huge batholithic granodiorite in its north. The distribution of the igneous rocks in the East coast block shows an entirely different features from those of Hanbacksan block. In the southern part of the block they assemble in a narrow area ranging in age from Early Proterozoic, through Middle to Late Proterozoic, Devonian, Jurassic, Cretaceous to Tertiary, whereas, the igneous rocks in the northern part of the block gathered to a restricted area, in ages of Middle Proterozoic and Cretaceous. The assemblage of the igneous rocks in the studied area shows a compositionally restricted, mixed S-type and I-type granites, $^{87}Sr/^{86}Sr$ > 0.706, rare volcanics and shortening with upright folding. These lithologic and structural features suggest that the igneous activity in this part related intimately to Hercynotype Orogeny of Pitcher(1979). Chronological episodes of igneous activity from Early Proterozoic to Early Tertiary in the northeastern part are figured.

The Osip-cheon river flowing on the east side of the Taeback mts. has formed river terraces on the several heights along the middle- and downstream. The river terraces are classified into 5 climatic ones and 7 thalassostatic ones. The thalassostatic ones are found to the height of 145-l50m level at 20-30m intervals. These vertical distribution is caused by the continuous uplift and periodical rise and fall of the sea-level. The high higher surfaces among the thalassostatic ones are the highest among those of Korea. The chronologies of the terraces are correlated to the marine oxygen isotope stages : The thalassostatic terraces on the level of 40 m.a.s.l. are to the stage 7, 70 m.a.s.l.. to the stage 9, 90 m.a.s.l. to the stage 9, 110 m.a.s.1. to the stage 11 and those of 150 m.a.s.1. to the stage 15 among the Interglacial Ages. The landuses and geomorphic landscapes of the Samchok area are chracteristic, because the karst landforms, such as doline and uvala, are developed on the surfaces of the middle-, the higher- and the high higher surfaces of river terrace.

Background: Nasal polyps are benign mass of nasal mucose, chronic sinusitis are swelling of nasal mucose, so nasal polyps and chronic sinusitis take a place at the same time. Nasal polyps are located lateral wall of nose, middle meatus, between middle nasal concha and inferior nasal concha. Objective: To demonstrate the effect of herbal medicine therapy in the chronic sinusitis and nasal polyps before and after treatment using computed tomography (CT). To compared before and after treatment of otitis media using earscope. Materials and methods: Five patients (4 mail and 1 femail) treated in our hospital between August 1998 and July 1999 were studied. Ages ranged from 9 to 23 years (mean age:13 years). All patients had a underlying family history, and past history(allergy or sinusitis of parents or brothers). Illness period was from 1 to 36 months (mean period:10.5 month). To ascertain the efficacy of treatment, CT were checked out. In the CT, three images were obtained 2cm interval on the coronal and axial plan. We classified treatment period into the type of allergic disease. Gamihyunggyeyungyo-tang was administered mainly. Gamigwaghyangjeungki-san, Gamizwakwi-eum and Gamihyangso-san were administered for through oral route additional symptoms. Results: Treatment period was from 126 to 157 days (mean period:140.7 days). To 3 patients with chronic sinusitis and nasal polyp, treatment period was 140.7 days, to 2 patients with otitis media and chronic sinusitis and nasal polyp, treatment period was 141.5 days. So they had no significance. Not nasal polyp from middle meatus, but also polypoid mucosal change of maxillary sinus is polyps Conclusion: We know that herbal medicine therapy is the effective treatment of pediatric chronic sinusitis and otitis media using earscope and CT. Herbal medicine therapy was effective in increasing immunity, inhibiting allergic reaction and inflammation of respiratory system. we practice ECP(eosinophil cataionic protein) and MAST examination, objectify herbal medicine therapy.

As the percentage of the elderly in the population increases, research to identify the nutritional and health status of the elderly, to understand the factors influencing on them, and to delay aging have been done actively. It is necessary for these studies to be longitudinal. This study was carried out to assess the change of health-related habits such as dietary behaviors and smoking, alcohol drinking and exercising habit, and health status between previous study(1991/1994) and post study(1998) for middle-aged men and women living in Chonju. For the present study, the data of 63 pairs(23 men and 40 women) were analyzed. They were 11 men and 12 women followed up from 82 men and 100 women surveyed in 1994. Mean ages in the 1991/4 and 1998 studies were 53.6y(range 42-63y) and 59.0y(range 46-72y) respectively. The survey was conducted with interview using a questionnaire including dietary behaviors and health-related habits, and anthropometric measurement and blood test for analyzing biochemical indices in 1991/4 and 1998. To understand these changes over time, $\chi$$^2$-statistics, t-test and paired t-test were analyzed with an SAS package program. As people age, there were significantly decreases in the proportions to eat lightly salted foods and drink alcohol. Significant longitudinal increases in triceps skin fold thickness, ${\gamma}$-GPT and HDL-cholesterol and significant decrease in hemoglobin value were noted over time in both men and women. In addition a significant decrease in blood glucose level was noted over time in women. Weight, blood glucose and total cholesterol increased significantly with age in those had had breakfast regularly or those had not used more slat at the table in the past. From this study, were found out the subjects of this study had relatively desirable health-related habits. But as improper health-related habits are likely to result in inappropriate health status(eg, increase in WHR, triglyceride, total cholesterol and LDL-cholesterol), it is recommended that nutrition education in necessary as soon as possible to meet the health elderly.

The aim of this study was to investigate the impact of participation in the 622 km hyper-ultra-marathon on hepatic metabolism and renal function in middle-aged men. Healthy middle-aged male amateur ultra-marathoners between the ages of 40 and 60. Blood was collected at the pre-race, immediately after 300 km, 622 km hyper-ultra marathon race, 72 hours (3 day) and 144 hours (6 day) after the race, AST (aspartate aminotransferase), ALT (alanine aminotransferase), ALP (alkaline phosphatase), ${\gamma}$-GTP (gamma glutamyl transferase), T-Bil (total bilirubin), D-Bil (direct bilirubin), T-protein (total protein), albumin, uric acid, BUN (blood urea nitrogen), creatinne were analyzed. ALP was significantly increased at 300 km, 622 km, day 3 and day 6 than the pre-race. ${\gamma}$-GTP, T-protein, albumin, uric acid, BUN and creatinine were not significantly different between the distances and the recovery period respectively. AST and ALT were significantly increased at 300 km, 622 km, day 3 and day 6 than the pre-race, respectively (P<0.05) at day 3 and day 6 they showed significant decrease from 300 km and 622 km, respectively (P<0.05). T-Bil and D-Bil increased significantly at 300 km and 622 km, respectively (P<.05) and significantly decreased at day 3 (P<0.05) compared to the pre-race, at day 3 and day 6 they were decreased significantly than 300 km and 622 km, respectively (P<0.05). In conclusion, no disturbance of renal function was observed according to the distances and between the recovery period of 622 km hyper-ultra marathon race, but reversible hepatocyte function could be degraded and some hemolysis of blood vessels was induced.

The purpose of this study was to identify a relationship between housework hours and fatigue level in middle-aged women. The subjects were 204 women living in Seoul and near the city, ranging in ages of 30-59(mean = 41.6 year) and were interviewed during the month of Oct. to Dec. 1999. The following questionnaires were utilized in this study: a self reporting housework time measurement table and a fatigue symptom scale originated from Yoshitake (1978). The analysis of the data was done by SAS program, t-test, ANOVA, and Pearson correlation. The results of this study were as follows : 1. Total mean hours of housework of the subjects were shown 9.2 hours on weekdays and 8.9 hours on weekend. Mean hours according to the area of houseworks on weekdays and on weekend were preparing and providing meal 3.9 and 4.2, doing laundry and maintaining clothes 3.1 and 1.6, keeping and maintaining house 1.6 and 1.4, caring family 1.3 and 1.2, and keeping household records 0.5 both. 2. With respect to the general characteristics of the subjects, there were significantly difference in age, job, religion, type of family, number of children, experience of present and previous illness, and perceived body size. 3. Average fatigue scores of the subjects were 16.6 of total score 60. Fatigue scores by the area were neuroperceptive fatigue 6.5, mental fatigue 5.2, and physical fatigue 4.9 in order. There were significantly differences in the score of fatigue by religion, number of family, present illness, and perception of body size. 4. There were significantly positive relationships in the scores of fatigue with the total hours of housework, preparing and providing meal, doing laundry and maintaining clothes, keeping and maintaining house, and caring family. 5. The physical fatigue scores were positively related with the areas of preparing and providing meal, doing laundry and maintaining clothes. While the mental fatigue scores were positively related the areas of preparing and providing meal, caring family, and keeping and maintaining house, and neuroperceptive fatigue scores were positively related with the areas of keeping and maintaining house and caring family. The recommendations from this study were further studies to investigate how middle-aged women manage their fatigue level, increase public awareness of middle aged women's fatigue level, and develop programs for middle-aged women to help with high fatigue.

Digital accessibility of the middle-aged and elderly has been increasing at a faster pace than other groups such as the handicapped and adolescents. However, studies related to the digital accessibility of middle and older adults are scarce. In order to examine variables affecting accessibility to digital information of the middle-aged and elderly people, this study researches the impacts of sociodemographic, physical and mental health and social activity variables on the accessibility of digital information. We analyzed data of 1,661 people between the ages of 55 and 84 from the 2018 Status Survey on Digital Divide conducted by the National Information Society Agency. The hierarchical multiple regression analysis shows the higher education, economic, and life satisfaction levels are, the higher digital accessibility levels of both male and female are. The result of the analysis also shows that the aged male has a higher accessibility level when he does not live alone; meanwhile, the aged female has higher digital capability as her age is lower, which describes that there are differences between gender. We expect the result of this study to be used as an important reference to understand factors related to digital accessibility level and active intervention for improving digital accessibility of the middle-aged and elderly male and female.

The purpose of this study is to propose criteria for selecting picture books as various reading education materials for middle school students and to check whether it can be applied to book selection. First, identified the educational value of picture books as reading materials and the criteria for selecting picture books by academic field through previous studies. After integrating the commonalities of various picture book selection criteria presented in previous studies by categorizing them into illustrations, text, and other categories. And it devised selection criteria that can be applied after selecting middle school students as readers. Based on the unified picture book selection criteria, a survey was conducted to ask in-service librarians about the main criteria to consider when selecting picture books for middle school students, and intensive interviews were conducted with experts who have experience in picture book education. As a result, the picture book selection criteria from previous studies were revised and supplemented with two criteria related to text, four criteria related to pictures, and five other criteria, and presented as picture book selection criteria for middle school students. To verify the practicality of the picture book selection criteria, it checked the applicability of each category of criteria to picture books recommended by the Children's Book Research Society (ages 13 and older). Out of 22 picture books for middle school students, 15 books could be applied to all categories of the selection criteria, showing significant practicality.
