This study was carried out to investigate effect of education for breastfeeding on practice of breastfeeding 171 primiparae (experimental group with education 83 and control group without education 88) who gave birth in hospitals located in Taegu City from October 25, 1999 to December 25, 1999 and planned to breastfeed their children after childbirth. The results of this study were as follows. 1) The experimental group's practice rate of breast-feeding was statistically higher than the control group's at the points of two weeks, four weeks, eight weeks and twelve weeks after childbirth(p<0.05). However, the rate at the points of sixteen weeks and twenty weeks after childbirth was higher in the experimental group than in the control group but there was no significant difference between both groups. 2) The experimental group's discontinuance rate of breast-feeding was lower than the control group's at all the points of two weeks, four weeks, eight weeks, twelve weeks, sixteen weeks and twenty weeks after childbirth, and it was statistically significant(p<0.05). The discontinuance rate of breast-feeding at the point of four weeks after childbirth was the highest in both groups. It accounted for 25.5% in the experimental group and 36.8% in the control group. 3) The reason of which the rate appeared to be the highest among those for discontinuance of breast-feeding was the lack of breast milk. The rate accounted for 65.5% in the experimental group and 50.7% in the control group. In conclusion, the study suggested that the education for encouraging breast-feeding provided to the primiparae after childbirth has an positive effect on the practice of breast-feeding.

This systematic review aimed to analyze the efficacy of corticosteroid premedication compared to placebo or no treatment to reduce postoperative pain in endodontic patients. Randomized controlled trials (RCTs) assessing corticosteroids via oral, intramuscular, subperiosteal, intraligamentary or intracanal route compared to passive or active placebo, or no treatment were included. Four databases were searched: PubMed, Web of Science, Cochrane Library and Embase up to 2/21/2018. Risk of bias was assessed with Cochrane Risk of bias tool. Fourteen RCTs with 1,462 generally healthy adults in need of endodontic treatment were included. 50% of the studies were at unclear risk and 50% at high risk of bias. Meta-analysis showed Visual Analog Scale (VAS) pain at 4-6 hours after Inferior Alveolar Nerve Block (IANB) was significantly lower by 21 points (0-100 scale) in the corticosteroid group compared to the control group (95% CI -35 to -7; P = 0.003), however this difference was not statistically significant after 24 hours (P = 0.116). The route of administration was oral and intraligament injection. Patients who received corticosteroids prior to IANB were 70.7% more likely to have none or mild pain 4-8 hours after treatment (P = 0.001) and 13.5% more likely 24 hours after IANB (P = 0.013) than patients in the control group. In conclusion, corticosteroid administration (oral or intraligamental) may clinically reduce the level of postoperative pain at 4-8 hours after IANB, however the quality of the evidence was low/moderate due to risk of bias and heterogeneity. Further studies are recommended.

BACKGROUND/OBJECTIVES: The objective of this study was to describe the development process of the Korean Healthy Eating Index (KHEI) based on the Korea National Health and Nutrition Examination Survey (KNHANES). SUBJECTS/METHODS: The components of KHEI were selected based on Dietary Guidelines for Koreans, domestic and overseas dietary quality indices, and results of the analysis of association with chronic diseases. The standards for scoring of KHEI were selected based on the 2015 Dietary Reference Intakes for Koreans (KDRI). The KHEI scores of Korean adults were calculated using a 1-day 24-h recall data in the 2013-2015 KNHANES. RESULTS: The KHEI included eight adequacy components evaluating the proper intake of recommended foods such as fruit, vegetable, and milk and three moderation components evaluating the consumption of food that limit intake such as sodium and saturated fatty acid. In addition, three balance components assessing the balance of energy intake were included. The KHEI score was defined to range from the minimum of 0 point to the maximum of 100 points. Among Korean adults, the total KHEI score was 63.2 out of 100. Gender and age differences were found in the average of total KHEI scores. Women showed higher score than men (61.7 in men and 64.7 in women, respectively). By age group, 20s and 30s showed the lowest scores with 57.4 and 61.1 respectively, and the scores increased with age by peaking at 67.8 in ages 60-69 and slowed down again in ages 70 or over. CONCLUSIONS: The KHEI can be useful for establishing and assessing national nutritional policies and in epidemiological studies to assess the relationship between overall dietary quality and chronic diseases. KHEI will need to be continuously updated to reflect changes in dietary guidelines and the KDRI.

In the present, since a five-year plan for economic development which was started in the early 60's has been successfully promoted for a quarter century, with consolidation in a department of social welfare in our country the participation. in economic society for women is more required than any other times. As a professional occupation for women is incereaing through a high-standard specialization, I think the upbringing for productive woman expert who has a strong motive of accomplishment as a developed person as well as a technical and skilful capacity which can be contributed to the growth of organization is very important. So in this study, I am evaluating the technical disposition of character of professional nurses working with hospital and also trying to supply the basic data being served to th extension of a skillful ability as a nurse, understanding the important factor related to it. The research method applied here is that we used 527 of formed questionnaires which were distributed to 7 University and General Hospitals, somewhat large in a scale, located in Seoul as an analytical material. It was performed between October 11, 1988 and October 18, 1988. An implement which was invented by Cho Moo-Sung is used after being amended and supplemented, which can measure the disposition of professional character. The formation of questionnaires of the disposition of character is 26 totally, 10 for Open-disposition, 11 for Active-disposition, 5 for wise-disposition, and it was measured. 'Ye', or 'No' through an one-half-standard and the environment of hospital organization is composed 12 questions from one point of 'Very Good' to 5 points of 'Very Bad.' Collected materials were analysed through an electronic calculation into the average value, the standard deflection, percentage, person correlative number, $X^2-test, m$ stepwise multiple regression. Summarizing the result from this research is as follows; 1. The average age of the subjective person of this investigation is 28.6 and the average career as a nurse is 6.0 years. 2. The Open-disposition that technical nurses showed is mostly half and half. 3. The Active-disposition of professional nurses was discovered affirmative largely and what they said in their questionnaires describes that they are very active answering $88.2\%$ for the disposition of self-control, $87.3\%$ for the people who think the training more seriously. 4. It was found out that the wise·disposition of technical nurse showed $90.7\%$ of 'Yes' about a new alternative of inquisitive question and we can see a progressive and profound aspect here. 5. As technical character of nurses, mutual relations between Active-disposition, Active-disposition, and wise­disposition were very profitably revealed as 0.42 in justice relations and also suggested that relations between Open-disposition, Active-disposition, and wise-disposition are 0.27 and 0.20 respectively. 6. What nurses recognize about the environment of hospital organization is reasonably acceptable while they feel very bad about rewards and punishments showing average 3.1 comparing to average 2.2 about time­control each other. Considering the prosperity of Active-disposition upon the result what I mentioned above, th possibility which is contributed to the productive improvement of hospital organization is very great and I think it can be more developed as a professional woman who has a strong motive of accomplishment, in advance.

Along with the social interests and needs for health, the U-Healthcare Service as a new model to control individual dietary life and to prevent chronic diseases is now drawing the public attention. In this study, the characteristics of the requirement of U-Healthcare Service were investigated from subjects aged over 50 years old. As parts of the expectation to the U-Healthcare service, the customized clinical care & control (37.7%) and the systematic understanding of individual health state (21.4%) appeared significantly. And for the application of the U-Healthcare Service to the field of healthcare, the control of dietotherapy (43.9%) appeared higher than anything else and thus the customized service for individual dietotherapy seemed to be needed. Regarding the field of searching for health information, the disease control (35.6%), food materials (28.6%), and recipe for health foods (22.7%) appeared in sequence and revealed that the majority over 50% of subjects were interested in foods. The requirements for the information of dietary formula were also investigated through 5 points scaled questionnaires on respective topics of nutritive components, menus customized for corresponding health states (diseases), and the results obtained from surveys on respective topics all showed the needs for all information by representing each point value exceeded 3.9. Through the results obtained from this study, the provision of customized information enabling the nutritional control in accordance with individual states of health or disease was estimated to be needed for the popularization of U-Healthcare Service providing contents for dietary life of clients especially those of aged over 50 years.

The three air quality monitoring sites, analysed simultaneously PM-10 and PM-2.5, ie. Ihyeondong in industrial area, Manchondong in residential area, Pyeongnidong in streetside, among 13 air quality monitoring sites in Daegu area, were investigated the concentration distribution characteristics of PM-2.5 and PM-10 in the last 2 years (2011~2012). PM-10 concentrations exceeded annual average reference value ($50{\mu}g/m^3$) in Ihyeondong ($52.5{\mu}g/m^3$) and Pyeongnidong ($60.9{\mu}g/m^3$) but satisfied in Manchondong ($44.9{\mu}g/m^3$). All PM-2.5 concentrations exceeded EPA annual standard value of the United States ($15{\mu}g/m^3$) in three points, but also exceeded new control annual standard value ($25{\mu}g/m^3$) coming into effect in 2015. Seasonal concentration of PM-10 appeared the order of spring > winter > fall > summer, and in the case of PM-2.5, the order was winter > spring > fall > summer. Monthly concentrations of PM-10 and PM-2.5 were highest in February and lowest in September. Diurnal concentrations of PM-10 and PM-2.5 increased from 7:00 AM, and recorded the highest concentration between 10:00 AM and 11:00 AM. And after 6:00 PM it lowered continuously and tended to show fixed concentrations from evening until early morning. In addition, the concentration of fine particles during the week was higher than the weekend. The fluctuation in industrial area was larger than the residential area. At the PM-2.5/PM-10 ratio, summer was generally high, spring was the lowest. And, when yellow sand occurred, it was 0.32 to 0.42. It was very low compared to 0.54 to 0.64 during non-yellow sand times. This paper for the state and the characteristics of Daegu' fine particles (PM-10, PM-2.5) will be valuable to future researches of fine particles and air pollution management.

To survey the different view points about food service programs among parents and teachers, 2 types of questionnaires, which consisted of attitude, perception, satisfaction and demand of the food service program in child education centers, were used. The data was collected from 2450 parents and 450 teachers who attended a child education center in 16 provinces, nationwide. SPSS was used for descriptive analysis and ANOVA test and $X^2-test$. The frinding results were as follows. 1. The average serving size of meal (lunch) were 80 meals per day and 167 meals per day at large institutions. Mean cost of snacks was 14,709 won per month and mean costs of lunch were 29,319 won per month. The mean price was not significantly different according to the scale of institution. The numbers of servings of lunch, morning snack and afternoon snack were 5, 3.4 and 3.5 times per week each. $56.4\%$ of the institutions served meals to children in classrooms, but the national/public institutions, which were attending elementary school, served meals in a dining place in the elementary school. 2. Teacher controlled serving portion size of snacks $(79.6\%)$ and lunch $(88.8\%)\;and\;30.1\%$ of teacher did not allow leaving lunch food. The ratio of knowing about preserved meals of the teacher who worked at a small institution was significantly higher than the teacher who worked at large institutions (p<0.01). 3. Between parents and teachers, several different view points about school lunch programs were detected. Most parents and teachers wanted that the school lunch to be fully cooked and served at the child education institution itself, but $12.2\%$ of parents and $14.4\%$ of teachers wanted a catering service. The teachers group preferred 'lunch box from home' and 'home partially prepared lunch' as an ideal meal serving type than the parent groups (p<0.01). And there were significantly different view points about price factors in school meals, teachers group highly answered that operating expenses must be added in meal prices. 4. The teacher groups' priorities of education activities during meal time were a significantly lower score than parents group in overall education activities. Teacher and parent groups pointed out that individual sanitation activities were most important of the education activities during meal time, but promoting good eating habits was the lowest score in both groups. 5. 'Improving taste and food quality' was most urgent in food service at child education centers, but there were significantly different view points between parent groups $(64.5\%)$ and teacher groups $(43.8\%)\;(p<0.05)$. They answered at a lower percent in 'employee qualified person' and 'cost control' point to improve food service, but there were also different opinions between the two groups (p<0.01). 6. As to the matter of the advantages and disadvantages of catering services, two group answered that the advantages of a catering service were 'convenience' and 'to solve facilities and labor problems', disadvantages were 'lower in food freshness' and 'sanitation problems'. There were also several different view pionts in catering services, the parents groups were more anxious about food sanitation than teachers. This study found several different view points about school food services among parents and teachers. To improve food services at child education institutions, there is a need to adjust the differences between the two groups through interactive communication channels and education and to employ dietitians as taking charge of adjusting roles between the two groups.

In conjunction with a vertical network. horizontal geodetic control points provide the basic framework for topographic mapping and legal survey. The design of such networks as well as the technical means for obtaining their coordinates have been changed in time, and therefore Korea National Geographic Institute has planned and observed the precise geodetic network since 1975. The aim of this study is to investigate the systematic distortions of the precise geodetic network in Korea implementing by the simultaneous adjustment. The results show that there are large discrepancies between adjusted and public coordinates in Chun-nam and Kyung-buk areas. The coordinate discrepancies are mainly due to the non-rigorous adjustment method and the disregard of the orientation unknown of the first direction for some blocks.

The law for indicating the address based on the street name has taken effect in 1997. The address based on land-lot number will be changed to the address based on the street name giving odd numbers to the buildings situated on the left side and even numbers to the buildings situated on the right side per street. Searching locations by street name addresses is possible for residential areas, on the other hand, the system of finding locations is insufficient for farmlands, mountains and others, so it is unable to cope with crimes and emergency rescue. In order to make up for the weak points of street name address, the national point number, grid reference system was introduced for finding location of non-residential areas. Therefore, the purpose of this paper is to help the introduction the national point number. In this paper, we proposed a territory-oriented control point and grid range for the national point number. Numbering scheme of grid zone shall be alphanumeric, a two-letter pair Hangul and the grid coordinates in terms of Easting and Northing. We also proposed the notice area for the national point number and location of signs, application about the public and private sector.

The purpose of this study is to review foreign scenic inventory map for the systematic management of natural scenic resources. Several foreign cases were surveyed and analyzed to apply the scenery inventory map in domestic, such as Visual Resource Management(VRM) from United States Bureau of Land Management, Scenery Management System(SMS) from USDA Forest Service and Visual Landscape Inventory(VLI) from British Columbia Ministry of Forest's, that were already established scenery inventory maps. The results are as follows. First, the characteristic of Korean landscape is quite a different from those of north american's, which is much smaller and more complex in topography and land use. So, it would be difficult to apply foreign system directly and we need more researches to our own system. The multi-stepped landscape unit system is highly recommended. Second, scenic quality could be estimated by the pre-built database, such as land forms, vegetation, hydrology and land uses. Historical and cultural attributes should be complemented. Third, existing scenic integrity could be grasped by scenic damage, landscape alteration caused by human activities and land exfoliation. Also, subjective evaluation method should be supplemented by objective criteria through further detailed studies. Finally, about landscape view conditions, landscape control points should be surveyed and established in advance, and viewing distance, viewing frequency, amount of observers and public interests should be considered.
