이 연구에서는 전남 화순군에 위치한 운주사의 석조문화재를 중심으로 암석의 풍화대 형성과 풍화의 진행에 따른 암석학적 특성과 지화학적 특성을 종합 검토하였다. 이 결과를 중심으로 석조물을 이루는 암석의 기계적, 화학적, 광물학적 및 물리적 풍화에 영향을 미치는 풍화요소를 규명하였고, 이들을 정량화하여 석조문화재의 보존방안 강구를 위한 기초자료로 활용하고자 한다. 이 연구를 위하여 야외 정밀조사 및 총 18개의 시료(화산력 응회암 7점, 화산회 응회암 4점, 화강암류 4점, 화강편마암 3점)에 대한 전암분석과 암석의 특성 및 광물감정을 실시하였다. 또한 각각의 석조물에 대한 훼손현황을 반정량적으로 기재하였다. 운주사 일대의 지질을 이루는 암석은 화산력 응회암이며 대체로 N30-40W의 주향과 10~20NE의 경사를 갖고 있다. 이 화산력 응회암은 운주사를 중심으로 매우 넓게 분포하고 있으며 운주사 경내에 분포하는 석조물은 모두 화산력 응회암으로 조형되어 있다. 현재 운주 사 경내의 석조물들은 대부분 심한 균열의 발달과 함께 구조적 불균형을 이루고 있으며, 생물학적 오염 및 암석의 풍화가 상당히 진행되어 각력이 탈락하고 광물의 입상분해가 발생하는 등 풍화와 훼손양상이 아주 심각하다. 또한 석조물 곳곳의 철편과 시멘트 몰탈은 산화되어 적갈색의 침전물과 회백색의 침전물을 형성하고 있다. 이들 석조물에 대해 육안 훼손정도를 기재한 결과 대부분의 석조물들이 MD(moderate damage)에서 SD(severe damage) 등급의 훼손정도를 보이고 있다. 각 암석의 X선 회절분석 결과, 대부분의 시료들은 석영, 정장석, 사장석, 방해석 및 자철석 등의 광물로 구성되어 있다. 현미경하에서는 석영과 장석류가 심하게 변질되었으며, 타형의 결정형을 보이는 흑운모는 풍화되어 이차 풍화광물인 녹니석으로 변질되어 있다. 또한 응회암 곳곳의 열극대에 적갈색의 철분 침전물이 관찰되는 것으로 보아 암석의 내부까지 풍화가 진행되고 있음을 알 수 있다. 연구지역의 석조물을 이루는 응회암류는 Subalkaline, Peraluminous의 영역에 도시되며, 시료의
This project was a service-cum-research effort with a quasi-experimental study design to examine the health benefits of an integrated Family Planning (FP)/Maternal & Child health (MCH) Service approach that provides crucial factors missing in the present on-going programs. The specific objectives were: 1) To test the effectiveness of trained nurse/midwives (MW) assigned as change agents in the Health Sub-Center (HSC) to bring about the changes in the eight FP/MCH indicators, namely; (i)FP/MCH contacts between field workers and their clients (ii) the use of effective FP methods, (iii) the inter-birth interval and/or open interval, (iv) prenatal care by medically qualified personnel, (v) medically supervised deliveries, (vi) the rate of induced abortion, (vii) maternal and infant morbidity, and (viii) preinatal & infant mortality. 2) To measure the integrative linkage (contacts) between MW & HSC workers and between HSC and clients. 3) To examine the organizational or administrative factors influencing integrative linkage between health workers. Study design; The above objectives called for quasi-experimental design setting up a study and control area with and without a midwife. An active intervention program (FP/MCH minimum 'package' program) was conducted for a 2 year period from June 1982-July 1984 in Seosan County and 'before and after' surveys were conducted to measure the change. Service input; This study was undertaken by the Soonchunhyang University in collaboration with WHO. After a baseline survery in 1981, trained nurses/midwives were introduced into two health sub-centers in a rural setting (Seosan county) for a 2 year period from 1982 to 1984. A major service input was the establishment of midwifery services in the existing health delivery system with emphasis on nurse/midwife's role as the link between health workers (nurse aids) and village health workers, and the referral of risk patients to the private physician (OBGY specialist). An evaluation survey was made in August 1984 to assess the effectiveness of this alternative integrated approach in the study areas in comparison with the control area which had normal government services. Method of evaluation; a. In this study, the primary objective was first to examine to what extent the FP/MCH package program brought about changes in the pre-determined eight indicators (outcome and impact measures) and the following relationship was first analyzed; b. Nevertheless, this project did not automatically accept the assumption that if two or more activities were integrated, the results would automatically be better than a non-integrated or categorical program. There is a need to assess the 'integration process' itself within the package program. The process of integration was measured in terms of interactive linkages, or the quantity & quality of contacts between workers & clients and among workers. Intergrative linkages were hypothesized to be influenced by organizational factors at the HSC clinic level including HSC goals, sltrurture, authority, leadership style, resources, and personal characteristics of HSC staff. The extent or degree of integration, as measured by the intensity of integrative linkages, was in turn presumed to influence programme performance. Thus as indicated diagrammatically below, organizational factors constituted the independent variables, integration as the intervening variable and programme performance with respect to family planning and health services as the dependent variable: Concerning organizational factors, however, due to the limited number of HSCs (2 in the study area and 3 in the control area), they were studied by participatory observation of an anthropologist who was independent of the project. In this observation, we examined whether the assumed integration process actually occurred or not. If not, what were the constraints in producing an effective integration process. Summary of Findings; A) Program effects and impact 1. Effects on FP use: During this 2 year action period, FP acceptance increased from 58% in 1981 to 78% in 1984 in both the study and control areas. This increase in both areas was mainly due to the new family planning campaign driven by the Government for the same study period. Therefore, there was no increment of FP acceptance rate due to additional input of MW to the on-going FP program. But in the study area, quality aspects of FP were somewhat improved, having a better continuation rate of IUDs & pills and more use of effective Contraceptive methods in comparison with the control area. 2. Effects of use of MCH services: Between the study and control areas, however, there was a significant difference in maternal and child health care. For example, the coverage of prenatal care was increased from 53% for 1981 birth cohort to 75% for 1984 birth cohort in the study area. In the control area, the same increased from 41% (1981) to 65% (1984). It is noteworthy that almost two thirds of the recent birth cohort received prenatal care even in the control area, indicating that there is a growing demand of MCH care as the size of family norm becomes smaller 3. There has been a substantive increase in delivery care by medical professions in the study area, with an annual increase rate of 10% due to midwives input in the study areas. The project had about two times greater effect on postnatal care (68% vs. 33%) at delivery care(45.2% vs. 26.1%). 4. The study area had better reproductive efficiency (wanted pregancies with FP practice & healthy live births survived by one year old) than the control area, especially among women under 30 (14.1% vs. 9.6%). The proportion of women who preferred the 1st trimester for their first prenatal care rose significantly in the study area as compared to the control area (24% vs 13%). B) Effects on Interactive Linkage 1. This project made a contribution in making several useful steps in the direction of service integration, namely; i) The health workers have become familiar with procedures on how to work together with each other (especially with a midwife) in carrying out their work in FP/MCH and, ii) The health workers have gotten a feeling of the usefulness of family health records (statistical integration) in identifying targets in their own work and their usefulness in caring for family health. 2. On the other hand, because of a lack of required organizational factors, complete linkage was not obtained as the project intended. i) In regards to the government health worker's activities in terms of home visiting there was not much difference between the study & control areas though the MW did more home visiting than Government health workers. ii) In assessing the service performance of MW & health workers, the midwives balanced their workload between 40% FP, 40% MCH & 20% other activities (mainly immunization). However,
