This study was aimed how posteroanterior cephalometric measurements affect the perception of the patient about his/her facial asymmetry. One hundred orthodontic patients, over the age of 12, who required a posteroanterior cephalogram in the Department of Orthodontics of Chonnam National University Hospital were used as the subject. They were asked if they thought their faces are asymmetrical. Their responses were classified into 5 groups based on the level of asymmetry as follows : Definitely No, Probably No, Don't Know. Probably Yes, Definitely Yes. Nine linear and four angular measurements from each posteroanterior cephalometric radiographs were analysed on the standard of the line between crista galli and anterior nasal spine to show the extent of asymmetry. Through this comparative study, the following results were obtained. 1. As the deviation of menton and the midline discrepancy of the upper and lower jaws were greater, the perception of patients about their facial asymmetry was higher. 2. All the measurements from the group "Don't Know" showed no statistical difference with those of the groups "Definitely No" or "Probably No." 3. All the measurements from the group "Probably Yes" showed no statistical difference with those of the group "Definitely Yes." The above results suggest that it may be helpful for the orthodontic diagnosis to ask patients' perception of their own facial asymmetry.

One of the serious problems resulting from rapid urbanization is the disordence of boundary between the administrative region, urban planning region and actual uranized area. Therefore this study, as a preliminary approach providing the theoretical basis for the arbitrating these problems, is to figure out the princles and methods of regionalization. Three regions are classified: homogeneous region, nodal region and planning region, and two basic principles are identified: homogeneity principle and functional integration principle. Such methods as overlapping method, multivariate analysis and Dirichlet polygon are illustrated by the homogeneity principle. With the stages in the analysis of nodal regional system, according to the functional integration principle the methods of regionalization such as SMSA criteria, gravity models, central place models and linkage analysis are illustrated.

'The Standards Rule of Real Estate Appraisal Practice' which regulates appraiser's behavior and professional conduct was newly changed. The purpose of this study is to review the New Standards Rule theoretically and to suggest some ideas for the next revisions. The provisions in the existing Standards Rule for depreciation adjustment, depreciation method, capitalization method, concept of capitalization rate and expected rate of return were eliminated in the new rule. The new rule emphasizes Competency Provision, concise writing of appraisal report, objectivity and impartiality of appraisal practice. It also encourages the discounted cash flow analysis in applying income approach, recognizes appraisal consulting and business valuation as important areas of real estate appraisal, and requires to reconciliate indicated values of three approaches in deriving final value conclusion. The efforts of government and related associations to consist underdeveloped existing appraisal practices with recent appraisal theories and techniques are highly evaluated. To maintain the highest level of professional practice, the continuing process of evaluation and reconsideration of Standards Rule should be needed, especially in the problems related with the concept of Normal Value, appraisal review, Appraisal Standards Boards, specifications of appraisal manual, forms of appraisal reports, appraisal information systems, and so on.

Recently the legal concept of 'justified value' was changed: "Justified value is the most probable price of the subject land in the ordinary market under all conditions requisite to normal trade." The application of Monte Carlo simulation technique to estimate real estate value has remained the exclusive province of real estate appraisers. This study is the first attempt to estimate the most probable price of hypothetical office building using the Monte Carlo simulation technique. Three distributional patterns were assumed for the economic characteristics of similar properties such as potential gross income, vacancy and bad debt, operating expense ratio, capitalization rate: that is uniform distribution, normal distribution and observed actual distribution. EXCEL program calculated the most probable price estimates based 100 iterations, 1,000 iterations, and 10,000 iterations for each three distributional patterns. Because the value indicated by 10,000 iterations of observed actual distributional pattern is more reliable than the indications derived from the other iterations of other patterns, the final estimate of the most probable price would be 29,585 million Wons.

The model proposed in this paper is devised to analyze the influence which the economic development in a specific city exerts on the its surrounding rural area and other cities. As a background to the model, Christaller's classical Central Place Theory is used and newly interpreted in a view of the balance equilibrium of trade between the central place and its hinterland. If there is a certain trade relationship between the central place and its hinterland, it means that the hinterland should have the surplus products to pay for the services provided by its central place and the central place should also have the surplus products to pay for the imports from its hinterland. The spatial economic interactions like this between the central place and its hinterland operate as a mechanism for forming and maintaining the hierarchical system of central places. The total products in the national economy can be devided into the two parts, primary products and derivative or secondary products. The increase of the primary products in a rural sector, the lowest order place in the hierarchical system, is the basic force to derive the secondary products in the central places of the higher order than that one. The size of the secondary products in each central place depends upon the degree of the spatial economic integration between the central place and its hinterland. The increase of the products in the industrial sector exerts great influences on the existing urban system in a traditional rural society. These influence that the increase of the industrial sector in a specific city upon its hinterland higher central places can be identified by combinating the two concepts developed from Central Place Theory, that is, the equilibrium of trade balance and the spatial economic integration, with the Economic Base Theory and Regional Input-Output Analysis. This model is evaluated available to explain and provide theoretical basis for the various empirical findings in the fields of Geography and Urban Studies. These are as follows: 1) Central goods and serveces flow not only from the higher places to the lower places but also from the lower ones to the higher ones to the higher ones. 2) The higher the hierarchical order of a city is, the bigger the ratio of non-basic activities to the total activities in that city is. 3) The city-size distribution in a regional level shows the pattern of cenral places distribution but in a natitonal level it shows the pattern fitted to rank-size distribution. This model also can give much suggestions to the regional development policy. Many theoretical researches primarily concern on the influence to peripheral regions by the development of a center, that is, spread effect and backwash effect. But this model can explain the developmental impact of a specific center not only on its periphery but also on other cities in higher hierarchical orders. The development effect of a specific center can be devided direct effect and indirect effect. The diirect effect to its periphery is decreasing the amount of its products by the out-flow of the population and to the higher order centers is increasing the products by the transformation of industrial structure. The indirect effect to its periphery is increasing the amount of its products according to the foreward linkage effect in a later stage and to the higher orders centers is inducing the derivative production by the increase of production in its periphery. This model is based on the theoretical deduction so that its availability should be tested by the empirical analysis.

Purpose : This study was conducted to develop field triage, transportation, distribution, and prehospital care at a fire disaster by analyzing the victims of the fore that broke out at a bar in Incheon. Method : We analyzed the cases of the victims of a fire in Incheon in Oct. 1999. We determined the primary care hospital, the arrival time, the burn size, the outcome, and the injury type from the medical records, the concerned organ records, and interviews with concerned persons. Result : The total number of victims was 137: 56 prehospital deaths, 1 hospital death, and 80 survivals. The Pearson correlation coefficient between the burn size and the severity was -0.175. There were 121(89.6%) cases of inhalation injury, 59 (43.7%) cases of flame burns, 66 (48.9%) cases of hypoxic brain damage, and 16 (11.9%) cases involving other types of injury. Conclusion : The causes of death of the fire victims were inhalation injury and hypoxic brain damage due to CO poisoning and other toxic inhalants. We propose the use of a simple triage and rapid treatment(START) system and a reassessment the delayed category in fire disasters.

Objectives : Pneumoconisis and noise-induced hearing loss (NIHL) have been reported as main occupational diseases by the Special Health Examination. The Industrial Accident Compensation Insurance has reported various work-related diseases, however, these two diseases occupied almost a half of compensated cases. Therefore, it was not well known about the status of occupational diseases other than pneumoconiosis, NIHL, and cardio-cerebrovascular accident (CVA). This study was conducted to analyze claimed cases as an occupational disease, that was requested to the Korea Industrial Safety and Health Agency (KOSHA). Methods : The local office of the Korea Labor Welfare Corporation (KLWC) has asked the KOSHA for confirmation of claimed cases as an occupational disease. We analyzed 379 cases requested from KLWC, the Ministry of Labor, employers, unions and occupational health agencies from 1992 to 1999. Results : Male was 80.7 % of the requested cases. Their mean age was 42 years old and 75.5 % of them were more than 35 years old. The requested cases were increased rapidly from 25 cases in 1992 to 108 cases in 1999 and the accept rate was 50.7 %. The majority of requested cases were respiratory diseases(22.4%), cancers(18.5%), Neuropsychiatric problems(14.5%), and musculoskeletal problems(13.5%). The accept rate was high in reproductive, respiratory, musculoskeletal and digestive disorders and low in neuropsychiatric, renal and otologic problems and occupational cancers. 73.6% of them were caused by chemical agents, especially 28.5 % were by organic solvents. 67% of them were clinically confirmed at university hospitals. A half of the cases were from KyongIn area, even the request came from the whole country. Conclusions : A claim was common in workers whose age was over 35 years old and exposure history was over 10 years. The respiratory diseases and neuropsychiatric disorders were still main problems in occupational health and occupational cancers was increasing even though its accept rate was not high yet.
