For studying on the actual condition of the oral health control of the old there were invastigations on the Questions with the college of the old in Chonbuk as the central figure from June 1 to June 30, 1998 and the analyses about the frequency and the mutual relation through χ²-test. The results are as follow: 1. According to the result of the investigation into the actual condition about the oral health of the old, two times a day in the frequency of tooth brush per day was the highest at the rate of 50.35％, the use of dentifrice was 45.4％, and the exchanging time of tooth-brush after six months was the highest at the rate of 19.7％. And 96.1％ didn't use dental floss and 73.6％ didn't do scaling. It is thought that since 50％ used tooth sticks and match sticks we have to inform the old of the necessity of dental plague and period oral examination. 2. In oral health situation, it showed that the number of people who were very week was the highest at the rate of 37％ and there was the mutual relation between the use of tooth sticks and match sticks and present situation of oral health. And 54.93％ visited the dental clinic wethin a year, and 22.3％ among them made full denture. There was the mutual relation between the visit of dental clinic within a year and the consultation content and the number of people who teld that the consultation expense was very expensive was the higest at the rate of 27.8％ and 87％ didn't experience the oral education. So it is thought that we have to make an systematic education about the oral to the old and inform them of the necessity of oral health control. 3. We think it needs the establishment and plane of the systematic basis material and the oral education which is necessary in oral public industry for the dental preventive suitable to the characteristic of the old.

Two experiments were performed to investigate effects of background depth information on the judgment of two-dimensional shapes, using the Posner et al.'s(1969) physical match task. In both experiments, the focus was on whether the background depth information affects the decisions of physical shape sameness of two letters or figures presented successively. In Experiment 1, artificially constructed rues of linear perspective and texture gradient were used, whereas cues contained in a real road situation were used in Experiment 2. The results of both experiments showed that the depth cues affect the perception of two-dimensional shapes. That is, when two stimuli of the same physical shape were likely to be perceived differently due to the given depth cues, response accuracies('yet' in this case) decreased and reaction tines of physical match increased. And when two stimuli of the different physical shape were likely to be perceived the same due to the given depth cues, response accuracies('no' in this case) decreased and reaction times of physical match increased likewise. These results wert discussed in terms of some conceptual methodological problems of the previous studies on the shape constancy and the directions of future research.

Recently, metropolitanization and suburbization have been occurring mainly in large cities, and spatial miss-match between residential and employment areas has increased. Spatial miss-match is different in the metropolitan cities and other metropolitan cities in Korea. Seoul and other metropolitan cities have grown to become centers of business functions, while other metropolitan cities have been transformed into residential function centers. Accordingly, The reverse commuting phenomenon is occurring in the rural metropolitan. The reverse commuting phenomenon limits the employment opportunities of specific classes among urban residents, and cause various problems such as environmental pollution and traffic congestion. Therefore, many studies on spatial mismatch and reverse commuting have been conducted, but a number of studies have been conducted on the Seoul metropolitan area, and research on other metropolitan areas is insufficient. The purpose of this study is to analyze the cause of the commuting phenomenon in the metropolitan area of the non-metropolitan area by considering spatial mismatch and understanding the reverse commutation situation in the local metropolitan area. This study is analyzed by a multi-level model and suggests the need for management of industrial location and expansion of residence in suburban.

The purpose of this study was to develop an Instrument for the Measurement of Cognitive Conflict Levels of students who confronted with an anomalous situation in science teaming. Anomalous situation is generated when students' prediction is disconsistent with the observed fact. In this study, the researchers identified 4 components of cognitive conflict and developed three items for each component. The items were developed and revised by four pilot tests. In the first pilot test, 55 elementary school students participated in the test In the second pilot test, 88 students of the 5th and 6th grader participated in the test. The instrument of measuring cognitive conflict levels was given to the subjects right after demonstrating anomalous situation. For the demonstration, two different problem situations were developed: one was a pulley problem and the other was electric bulbs in parallel. Answered reasons for each items were analyzed to assess students' understanding on each items. In third pilot test, 125 elementary school students participated in the test. A factor analysis of the responses was carried out and reliability of the test was assessed by calculating internal consistency values. The items were finalized by three pilot tests. After 1 month after the third pilot test, researchers conducted the finalized test items to 323 students of the 5th and 6th grader. The final instrument showed moderate reliability (Cronbach-α 0.82∼0.87) and good content validity(0.93). A factor analysis of the response was carried out. 4 main factors completely coincided with 4 components that we supposed to be the conducts of cognitive conflict. The instrument can provide a means for both teachers and researchers to assess the cognitive conflict of a large number of students within a single class period. The results can be used by teachers to better understand the process of conceptual change of their students and to match instruction and materials accordingly.

The purpose of this study was to investigate the effect of fouls on performance in field hockey games. A total of 33 matches and 2101 fouls from 10 teams participated in the 2017 World League SEMI-FINAL tournament were analysed by region, race, type, and cause. The total data that is analysed by SportsCode and SPSS(correlation analysis & chi-square test)have showed that the top ranked countries had a higher foul frequency than the lower ranked nations. According to the situation that has showed the result of the analysis, it showed that there was no difference between the results analysed on the foul type and the attacking and defence situation but it has indicated that area, game situation and the cause of fouls showed there was a significant difference. On these results, it is hoped to use fouls as one of the tactical means in women's field hockey games.

WHEN IT IS REQUIRED TO CONNECT OVERHEAD TRANSMISSION LINE WITH UNDERGROUND CABLE, PREVALENT METHOD WAS TO USE CABLE HEAD TYPICALLY MADE OF LATTICE STEEL STRUCTURE. BUT IN VIEW OF THE INCREASING DEMAND THAT STEEL STRUCTURE INSTALLED IN URBAN AREA AND/OR RESIDENTIAL AREA NEED TO MATCH WITH ENVIRONMENTAL SURROUNDINGS, THE UNSHAPELY LARGE-SIZED LATTICE STEEL STRUCTURE CAN NOT BE A PROPER ONE BECAUSE THAT IT IS NOT WELCOMED BY THE RESIDENTS AND ACCORDINGLY ITS INSTALLATION TENDS TO CONFRONT WITH CIVIL PETITION. AS AN ALTERNATIVE METHOD TO SETTLE AFOREMENTIONED UNFAVOURABLE SITUATION WE MAY BE UNDER, WE AR INTENDING TO DEVELOP THE CABLE HEAD MADE OF TAPERED TUBULAR STEEL POLE AND TO PUT IT TO PRACTICAL USE. THE ADVANTAGE WE CAN TAKE OF THE TAPERED TUBULAR STEEL POLE IS THAT IT CAN BE INSTALLED IN A VERY LIMITED SPACE MAXIMIZING THE UTILITY VALUE OF THE LAND AND THAT ITS SMART SHAPE WITH COLOUR COATING IN CONSIDERATION OF AESTHETIC AESTHETIC CAN BE IN GOOD HARMONY WITH THE SURROUNDINGS.

Recently, dental PACS construction in dental hospital is fairly general. For this reason, inspection request works of dental PACS fee with Health Insurance Review & Assessment Service are more important for the financial stability in hospital and from now on status. But several departments in dental hospital, enforce a incoherent order system so inspection request situation is full of mistakes and omissions. As a result, financial stability in hospital rapidly change for the worse, as the case stands establishment of proper order system and match system is essential to resolve the issue. Consequently, we plan to establish the proposed idealized scheme.
