Water mains underground facilities are essential components to make up urban infrastructure. In order to manage these water mains underground facilities systematically and scientifically, GIS (Geographic Information System) had been constructed. For the sake of construction of GIS for water mains underground facilities, an exact underground detection and the construction of DB (Data Base) for buried water mains underground facilities should be preceded. In this study, in order to find out the ways to improve exact detection rate of data, the statistical analysis for the causes of detection raw degradation was done, and standardization methods of detection through a case study were suggested, When water mains underground facilities were measured, the detection of non-metallic water pipes was not carried out. The reason was that the results of detection was uncertain and detection was difficult because the assessment of public measurements was vulnerable. Moreover, due to the absence of standardized operating regulations for detection, systematic surveys weren't conducted. In this study, methods to standardize works over the detection of water mains underground facilities were presented so that we can improve the detection rate when we are doing that. As the proposals to improve detection rate, effective performance assessment over non-metallic pipes were presented, and related issues to supplement work regulations of public survey were described systematically.

Objectives : To evaluate the properness and effectiveness of the question categories concerning 'sasang constitutional characteristics of mind', used in Iksan Wonkwang Oriental Medicine. Methods : We statistically analyzed data from those 1335 patients focussing on 'relative discrimination ability' to sasang constructions and 'response ratio'. Patients included in this research are only those who had been well treated in Iksan Wonkwang Oriental Medicine during the Period of three years from 2000 to 2002. The data are obtained through the electronic chart developed by Kim Jong-Yeal, and analyzed using the statistical Package SPSS. Results: In total characteristics of mind, the question category of 'timid' has high discriminating power and effectiveness to Soeum type, more in women than men, and especially with an age of 21 or more; The category of 'hasty-tempered' to Soyang type in women with all ages and men with ages 21-40; The category of 'broad-minded' to Taeum type with ages 41 or more; The category of 'timid and broad-minded' to Soyang type, and especially high to women with ages 41 or more. Question categories concerning response type in anger were estimated to have different response patterns to sasang constructions only for ages 21 or more by $X^2$2 test. The question category of 'bear and last long' has high discriminating power and effectiveness to Soeum type, more in men than women, and increasingly to ages; The category of 'impatient and disarmed quickly' to Soyang type in both women and men, especially with ages 21 or more; The category of 'impatient' to Soyang type women or with ages 21 or more. Other categories have low discriminating power or low effectiveness. Concernig expression type of one's thought, the question category of 'straightly' has high discriminating power and effectiveness to Soyang type, more in wemen than men, and especially to ages 21 or more; The category of 'tender' to Soeum type, in women or with ages 40 or less; The category of 'indirectly' to Taeum type in men or with ages 41 or more; The category of 'straightly and stuborn' to Soyang type with ages 41 or more; The category of 'indirectly and tender' to Soeum with with ages 20 or less; The category of 'not express and tender' to Soeum type with ages 41 or more; Conclusions : Question categories concerning total characteristics of mind, response type in anger and expression type of one's thought, are partially discriminating and effective to specific constitution according to sex and ages, and some categories are more discriminating and effective when they are composited. But generally, the discriminating power of Taeum constitution group and group with ages 20 or less was too low, so it is necessary to develope question categories for those groups.

Safe blast criteria based on the concept of scaled distances can be obtained from the statistical analysis on measured peak particle velocity data of blast vibrations. Two types of scaled distance widely used in Korea are the square root scaled distance (SRSD) and cube root scaled distance (CRSD). In contrast to SRSD scheme, however, the function of maximum charge per delay for CRSD increases without bound after the intersection point of these two functions despite of the similar goodness of fits. To prevent structural damage that may be caused by the excessive charge in the case of CRSD, it is suggested that CRSD be used within a specified distance slightly beyond the intersection point. On the other hand, there are several attempts that predict vibration level(VL) from the peak particle velocity(PPV) or estimate VL based on the scaled distances without considering their frequency spectra. It appears that these attempts are conducted in blasting contracts only for the purpose of satisfying the environment-related law, which mainly deals with the annoyance aspects of noises and vibrations in human life. But, in principle there could no correlation between peaks of velocity and acceleration over entire frequency spectrum. Therefore, such correlations or estimations should be conducted only between the waves with the same or very similar frequency spectra. Finally, it is a known fact that structural damage due to ground vibration is related to PPV level, the safety level criteria for structures should be defined by allowable PPV levels together with their zero crossing frequencies (ZCF).

Since areas of pain and dysfunction of musculoskeletal typically suffered by the patients with back disorders spread all over the body, WBIP(GCM Program) for the primary treatment and management is required. The purpose of this study is to analyze if WBIP(GCM Program) based on the hyper/hypomobility pattern of Four Body Types can identify the effective treatment of back disorders and the effect on the postural balanced restoration of the spine and extremities. Non-specific back disorder is still a major reason for sick leave. And moreover, its been reported that there was often recurrence to the patients whose symptom had been diminished. As a WBIP(GCM Program) based on kinematic chain patterns of Four Body Types, this study gave a new information on the effective diagnosis, treatment and management of non-specific back disorders. 337 patients above the twenty-five years old with the non-specific back disorders at the hospital and oriental medical clinics at Kyungnam and Busan areas in South Korea from August 24th, 2000 to Feb 23rd, 2001 have randomly been assigned to four experimental groups such as Whole Body Intervention Program Group, Physical Therapy Group like modality treatments, Acupuncture-Treatment Group, and Placebo Control Group. According to intervention program applied to the each four group for three times per week(twelve times per 4weeks), as the time-series methods, we compared and evaluated the body status of the pretest with that of post treatment completion of four week, three month, and six month, respectively. As the analytical method of measurement, our researchers used the Moire Interferometry Unit and Postural Kit that could measure the postural balance of spine and extremities. The collection of data was performed in the designated hospital and oriental medical clinics. For the analysis of the data, the SPSS 10.0 package program was used. X2-test has been taken in order to compare and analyze characteristics and GPES of the patients in four experimental groups. Repeated Measure ANOVA and Tukey post hoc test has been adopted in order to compare the effects of the balanced restoration of the spine and extremities among four Groups categorized for this study. Statistical significance was accepted at the 0.05 level of confidence The effect of the balanced restoration on the spine and extremities of the patients with non-specific back disorders has been proved in all of the Groups. As for the restoration degree, however, WBIP(GCM Program) Group produced the highest effectiveness in terms of the fact that it had a dense moire in comparison with the other three Groups and that the Moires of both sides had the same level by the time(p<0.01). WBIP(GCM Program) based on four tilting types of scapular and ilium and hyper/hypomobility pattern took a higher effect on the balanced restoration of the spine and extremities through a whole body as well as the treatment of back disorders than the other three Groups which the usual remedy without classification of body type had been applied to.

The objective of this study is to analyze the factors affecting the pedestrian accidents of roundabout near schools. To this end, this study has focus on the comparative analysis of pedestrian accidents across different school areas. The traffic accident data from 2007 to 2014 are collected from TAAS data set of Road Traffic Authority. To develop the pedestrian accident rate model, the linear regression model has been utilized in this study. 28 explanatory variables such as geometry and traffic volume factors are used. The main results are summarized as follows. First, the null hypotheses that the number of pedestrian accidents are the same are rejected. Second, 5 multiple linear regression accident models with higher statistical significance (adjusted $R^2$ of 0.651~0.788) have been developed. Third, while the common variables of 3 models (model I~III) related to school location are evaluated to be the pedestrian island, crosswalk, types of roundabout, elementary school and bus stop. Fourth, while the common variable of 3 models (model III~V) related to near school area or not is evaluated to be pedestrian island, type of roundabout, sidewalk, elementary school, speed hump, speed limit sign and number of entry lane. As a result, the installation of pedestrian islands and crosswalk might be expected to decrease the number of pedestrian accidents near schools.

The primary purpose of this study is to promote and establish the development of home health care in Korea. It focuses on identifying and classifying the nursing activities that were provided by health professionals for patients who were admitted to two hospitals with cerebral vascular disease. And also. the study was conducted for comparison of client selection criteria between health professionals, and identifying patients who needed home health care The subjects of this study were 38 patients with cerebral vascular disease who were admitted to neuro-surgery wards at 2 hospitals with more than 500 beds in Daegu from November 1. through 30. 1991. Survey instruments were questionnaires to identify nursing activities and classify patients who needed home health care. Data was collelected by 1 doctor and 2 nurses per patient independently. They checked the same patient with the questionnaire on the same day and never communicated their information about patients with each other. All the questionnaires checked by doctor and nurses completely were 90. Statistical methods for analyzing data were non-parametric tests (Kruskal Wallice test and sign test). Correlation and percentages were used for further analysis. From this study. the following summarized conclusions have been drawn. 1. 10. 2 kinds of treatment and nursing activities were provided by health professionals for patients with cerebral vascular disease in hospital. 2. The points of nursing needs were between 32-37 out of a total of 500 as a result of the assessment about the health status of patients who were admitted to neuro-surgery ward with cerebral vascular disease. The points of Barthel Index of Functional Status Assessing Devices were between 24-34. Client Selection Criteria for Home Health Care was congruent between the Health professionals because the difference were not found to be statistically significant. 3. Patients classfied as home health care clients were $70-80\%$ of all patients who were admitted in hospital. There was not significant difference in patient selection criteria for home health care between health professionals statistically. As a result. the validity of different tools used in classifying home health care client were found to be congruent. 4. $80-85\%$ patients who could be discharged and sent to their homes early were identified as home health care clients. This study using client selection criteria. for home health care contributed to tool development because the validity of tools was verified. And also, this research represented that there was congruency in patient selection criteria for home health care between different health professionals. As a result, this study represented that many patients who were admitted to hospitals could be classified as a home health care clients. On the basis of the findings. further studies are required to develop client selection criteria using universal tools for classifying home health care clients in other chronic diseases. It is also recommended that comparative studies for client selection criteria between health professionals treating in other chronic diseases are necessary.

The purpose of this study was to investigate the real condition of hospital marketing and concrete strategy on medical consumers need for enhance the effectiveness of hospital management. The data were collected from January 27 to February 3, 2000 at a general hospital located in M city to 205 in-patients and out-patients by questionnaires. The research tool was based on literatures. The data was analysed by the use of percentage, mean, t-test and ANOVA by SAS(Statistical Analysis System) Package Program. The results of this study are summerized as follows: 1. Mean score of the marketing mix (4P 's) was 3.1 in total and each mean score was 3.6 in product, 2.5 in prices, 3.3 in place and 3.1 in promotion. The following are the items which received the highest scores in each: 'The hospital is clean' in service category; 'the prices of meals at the restaurant the patients' families use are reasonable ' in price sphere. In distribution, 'it is easy to locate the hospital' and in promotion,'we'll use this hospital again' and 'we'll recommend this hospital to others'. 2. Marketing mix factors(4P's) was significantly different on the general characteristics in terms of marriage status, occupations and the period of hospitalization. 3. The most important reason for choosing this hospital was 'This is a general hospital with good facilities' and the next were 'The hospital staffs are kind and the hospital is clean' and 'The traffic is convenient to come'. The most important factors contributing to a good image formation of the hospital were 'this is a clean hospital', 'This is a hospital with kind people' and 'this hospital is equipped with good medical facilities'. 4. The factors for making a good image concerning the nursing service were professional knowledge, good nursing skills and kindness. After grasping the marketing conditions of the hospital aided by the above-mentioned research results, the researchers concludes that it is necessary to develop an institutionalized service strategy to increase the satisfaction the patients feel about the hospital facilities and kindness of the staff and as a result, to differentiate it from other medical institutions.
