  • 본 연구를 통해 토양 방선균 유래 제초활성물질을 대상으로 제초제로서의 적용 가능성 여부를 확인하기 위하여 수행되었다. 잡초에 대한 발아와 경엽처리에 대한 약효시험 결과, 종자 발아는 100 ppm 수준으로 처리하고 경엽에는 2,000 ppm 수준으로 처리해야 저해효과를 나타냈다. 작물에 대한 시험 결과, 오이는 발아억제가 이루어지지 않았으며 벼는 발아와 생육 모두 50% 내외의 저해를 보였다. 그 외의 모든 시험 작물 초종은 처리 농도에 따른 민감한 반응을 보였다. 즉 토양방선균으로부터 발굴한 천연제초활성물질은 선택성 제초제로의 개발은 어려워 보이나 비선택성 제초제로의 개발은 가능할 것으로 보인다. 한편 처리방법에 따른 농도별 시험 결과, 패트리디쉬에서 실험의 경우 모든 잡초종이 농도에 민감히 반응하였으며, $GR_{50}$값은 1-2 ppm 정도를 보였다. 그리고 토양처리 효과에 따른 발아억제 및 생육저해 효과는 쌍떡잎식물에서 보다 민감한 반응을 보였고, 털비름의 경우 1,000 ppm에서도 85%의 생육저해를 보였다. 경엽처리에 따른 생육저해 조사시 2,000 ppm에서 피는 고사하지 않았으나 나머지 초종은 모두 고사하였고, 특히 털비름은 6.25 ppm의 농도에서도 고사하였다. 경엽처리에 따른 대표적인 반응으로 바랭이는 잎의 꼬임현상을 나타냈고, 어저귀는 잎이 변색되었다. 토양처리는 그 효과가 경미하고 일정기간 경과후에 재생되어 방제효과가 부족하였으며, 경엽처리의 경우 피를 제외한 잡초종등이 2,000 ppm에서 방제가 가능할 것으로 보인다. 또한 모든 결과를 종합 할 때 화본과잡초 보다 광엽잡초에서 민감한 발아억제 및 생육저해 효과를 볼 수 있었다. 따라서 토양 방선균 유래 제초활성 후보물질은 비선택성 경엽처리제로서의 개발이 상대적으로 유망할것으로 판단되었다. 한편 화본과 잡초에 대한 저해 효과가 부족함으로 추후 다른 제제와 혼합함으로써 화본과 잡초도 동시에 방제할 수 있는 기술의 개발이 필요할 것이다.

  • 본 논문에서는 경남일대 동 광화대에 위치하는 삼봉광산의 함 동-연-아연-은 열수 석영맥을 대상으로 황화 광석광물의 광물학적 특성을 규명하였다. 백악기 경상 퇴적 분지의 상부 지층인 칼크-알카리 화산암류 내에 발달된 $N-S{\sim}N13^{\circ}W/65{\sim}85^{\circ}W$의 제 단층 열극면 및 압쇄대를 따라 수 개조의 평행한 함 동-연-아연-은 열수 석영맥이 0.5-1.5Km 연장 부존되어 있다. 주 광석광물은 황동석, 방연석, 섬아연석, 황철석 등이며 맥석광물은 석영, 방해석, 견운모, 녹리석 등이다. 이들 광물로 구성된 함 동-연-아연-은 석영맥 내에 있어서 부광대의 발달은 구조 규제를 받고 있으며, 수평 및 수직적 방향에 있어서 조성광물의 대상분포 현상을 보여준다. 열수광화작용은 시기적으로 3회에 걸쳐 진행되었다. 광화 제 1시기(Stage I)는 미량의 황철석과 황동광이 수반하며 제 2시기에는 황동광, 방연광, 섬아연석과 극미량의 제유화 광물을 수반하는 개발대상의 석영맥(Stage IIa and IIb)이 형성되었고, 제 3시기에는 이들 석영맥의 약석대를 따라 최후의 방해석맥 (carbonate stage)이 형성되었다. 주조성 광물과 부성분 광물(황동석, 방연석, 섬아연석, 황철석, 유비철석, 백철석, 에나자이트)을 대상으로 물리적 특성을 실험하고, 광물의 형성단계, 부성분, 결정면의 방향과의 상관성을 밝히며 금속광물의 감정을 위한 제 자료를 제시하고자 반사도와 미경도를 실험 연구하였다 광화시기에 따른 반사력의 특성은 광화작용중 열수계의 물리 화학적 환경의 변화에 따른 광물의 성분 및 구조적 차이에 기인되는 것으로 고려된다. 섬아연석의 반사력과 굴절률은 Zn을 치환하는 철 함량에 정비례하며, //(100) 결정면에서 //(111) 결정면 보다 높은 값을 보여준다. 정성, 정량적인 부성분에 의한 내부반사(백색광하)를 +니콜하에서만 보여주는 경우 섬아연석은 정상 반사력의 값을 가지나, //니콜하에서도 내부반사를 보이는 것은 매우 상이한 spectral dispersion을 나타내는데, 내부 반사광과 같은 파장($544m{\mu}$, $593m{\mu}$, $615m{\mu}$)에서 선택반사 효과는 최대가 된다. 불투명 이방성 광석광물인 황동석은 2축성(-)이다. 표준 하중별로 실시한 빅카의 미경도 실험에서, 섬아연석은 100g 하중하에서 철함량이 8.05%에까지 증가함에 따라 미경도 값이 급격히 증가하나 철 성분이 더 많으면 다시 감소하는 경향을 보여준다. 섬아연석은 //(100) 결정면에서 //(111) 결정면보다 미경도 값이 크며, 방연석 //(111), //(210), //(100)의 순으로 결정방향에 따라 미경도 값이 작아진다. 경도가 작은 유화광물 일수록 indentation의 대각선 길이의 변화폭이 크며, 실험 광물에서는 황철석 섬아연광 황동광 방연광 순으로 증가된다. 한편 모든 실험 광물은 결정방향에 따라 각각 특징적인 indentation의 형태와 단구를 갖는데, 이는 광물감정과 결정면의 방향을 규명하는데 좋은 자료가 된다.

  • The purpose of this study was to examine the effect of aroma therapy on anxiety and pain before and after tooth extraction. The subjects in this study were 60 patients who felt severe anxiety and pain due to tooth extraction. The experiment was conducted from January through March, 2004, by organizing an experimental group and a control group with 30 patients each. The experimental group was asked to keep wearing lavender-containing necklaces from two days before tooth extraction to inhale lavender, and no such an action was taken to the control group. The collected data were analyzed with SPSS 10.0 program to obtain statistical data. and ${\times}2$ test and t-test were implemented. The findings of this study were as follows: 1. Regarding whether or not the experimental and control groups were homogeneous, men outnumbered women, and the largest number of the patients were in their 30s. Those who were married were more than the others who were unmarried in number, and those who lived with their spouses under the same roof together outnumbered the others who didn't, as the rate of the former stood at 65 percent in the experimental group and 86.4 percent in the control group. They expressed high satisfaction at their spouses, since 45 percent of the experimental group and 31 percent of the control group did it, but the difference between them and those who were unsatisfied was insignificant (pE0.347). By occupation, the largest number of people in the experimental group, which numbered 16.7 percent, were self-employed, and lots of patients in the control group were government workers. As for blood type, type A was most prevailing, which recorded 43.3 percent. By religion, 43 percent of the experimental group had no religion, whereas 36.7 percent of the control group were Christian. The most common monthly income ranged from 2 million to 2.5 million won. 2. There was little disparity in past pain experience between the two groups before aroma therapy was applied. The experimental group underwent more pain (6.15) than the control group (5.78), but the difference wasn't significant. The experimental group (90%) experienced more anxiety and fear than the control group(83%), but the difference was insignificant. This fact showed that there was little gap between the two groups in anxiety and fear caused by tooth extraction. Contrary to earlier expectation that pre-anxiety might not be the same. little significant difference was found. 3. After aroma therapy was applied, 50 percent of the experimental group and 23.3 percent of the control group suffered significantly less anxiety and fear about tooth extraction(${\times}2$=4.59, pE.05). And the experimental group exposed to aroma therapy was less nervous(3.0) than the control group(4.39), and the gap between the two was significant (t=13.37, pE.001). Therefore, aroma therapy had a good effect on alleviating their anxiety. During tooth extraction. 73.3 percent of the experimental group and 93.3 percent of the control group felt pain. The former group suffered Significantly less pain(${\times}2$=4.32, PE.05). Concerning the extent of pain, the experimental group(2.53) found it less painful to have their teeth extracted than the control group(5.50), and the gap between the two was significant(t=5.89, PE.05). 4. As to the effect of aroma therapy on alleviating anxiety or fear, the experimental group(33.3%) felt that aroma therapy let them more relieved. Every member of that group was willing to use aroma therapy again in the future, and 86.7 percent of that group perceived that aroma therapy made a difference to dental treatment. The experimental group responded to aroma therapy favorably, as every member of it had an intention to advise others to use that therapy.

  • 제2차 고기후 모델링 비교 프로그램(Paleoclimate Modelling Intercomparison Program phase II, PMIP2)의 대기-해양-해빙 접합모형을 통해 얻어진 시뮬레이션 자료를 이용하여 마지막 최대빙하기(Last Glacial Maximum)의 북극 기후변화를 연구하였다. 연구에 이용된 모형은 미국 해양대기청의 CCSM, 독일 막스플랑크 연구소의 ECHAM3-MPIOM, 영국 기상청의 HadCM3M2, 프랑스 라플라스 연구소의 IPSL-CM4, 프랑스 기상연구소의 CNRM-CM3, 일본 동경대 기후연구소의 MIROC3.2, 그리고 중국 대기물리연구소의 FGOALS을 포함해 총 7개로 구성된다. 7개 모형들에 의해 재현된 현재 기후를 관측에 기초로 한 재분석 자료와 비교해 본 결과, 모든 모형에서 관측에 나타나는 북극기후의 특징들이 비교적 잘 재현되었다. 모든 기후 모형들에 마지막 최대빙하기의 대기 이산화탄소 농도를 포함한 온실기체, 지구공전궤도함수, 그리고 빙상 및 지형의 경계 조건이 적용되었다. 빙하기 경계 조건에 대하여 대륙빙하가 발달했던 북미와 북유럽에서 $24^{\circ}C$ 이상의 온도 감소가 나타나는데, 이는 빙하의 발달에 따른 표층의 알베도 증가와 고도의 증가에 기인하는 것으로 여겨진다. 또한 빙하의 발달에 기인하여 북극해에서도 $10^{\circ}C$ 이상의 온도 감소가 나타난다. 여름철에 비해 겨울철 온도 감소가 대체로 더 크게 나타나며, 북극 주변에서 평균 약 $14^{\circ}C$ 정도의 연평균 온도 감소를 보이고 있다. 저위도에 비해 북극 지역의 온도 감소가 모든 계절, 특히 겨울철에 더 크게 나타나는데, 이는 최근 지구 온난화의 정도가 극 지역에서 저위도나 중위도에 비해 더 크게 나타나고 있는 것과도 잘 대비된다. 본 연구결과와 최근의 온난화가 서로 대비되게 일어나기 때문에, 마지막 최대빙하기의 연구를 통해 미래 지구온난화 하에서 나타날 수 있는 기후변화를 간접적으로 이해할 수 있을 것으로 사료된다.

  • 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, $85{\sim}90%$ of the services provided by the health workers were other than FP/MCH, mainly for immunizations such as the encephalitis campaign. In the control area, a similar pattern was observed. Over 75% of their service was other than FP/MCH. Therefore, the pattern shows the health workers are a long way from becoming multipurpose workers even though the government is pushing in this direction. 3. Villagers were much more likely to visit the health sub-center clinic in the study area than in the control area (58% vs.31%) and for more combined care (45% vs.23%). C) Organization factors (admistrative integrative issues) 1. When MW (new workers with higher qualification) were introduced to HSC, it was noted that there were conflicts between the existing HSC workers (Nurse aids with less qualification than MW) and the MW for the beginning period of the project. The cause of the conflict was studied by an anthropologist and it was pointed out that these functional integration problems stemmed from the structural inadequacies of the health subcenter organization as indicated below; i) There is still no general consensus about the objectives and goals of the project between the project staff and the existing health workers. ii) There is no formal linkage between the responsibility of each member's job in the health sub-center. iii) There is still little chance for midwives to play a catalytic role or to establish communicative networks between workers in order to link various knowledge and skills to provide better FP/MCH services in the health sub-center. 2. Based on the above findings the project recommended to the County Chief (who has power to control the administrative staff and the technical staff in his county) the following ; i) In order to solve the conflicts between the individual roles and functions in performing health care activities, there must be goals agreed upon by both. ii) The health sub·center must function as an autonomous organization to undertake the integration health project. In order to do that, it is necessary to support administrative considerations, and to establish a communication system for supervision and to control of the health sub-centers. iii) The administrative organization, tentatively, must be organized to bind the health worker's midwive's and director's jobs by an organic relationship in order to achieve the integrative system under the leadership of health sub-center director. After submitting this observation report, there has been better understanding from frequent meetings & communication between HW/MW in FP/MCH work as the program developed. Lessons learned from the Seosan Project (on issues of FP/MCH integration in Korea); 1) A majority or about 80% of the couples are now practicing FP. As indicated by the study, there is a growing demand from clients for the health system to provide more MCH services than FP in order to maintain the achieved small size of family through FP practice. It is fortunate to see that the government is now formulating a MCH policy for the year 2,000 and revising MCH laws and regulations to emphasize more MCH care for achieving a small size family through family planning practice. 2) Goal consensus in FP/MCH shouBd be made among the health workers It administrators, especially to emphasize the need of care of 'wanted' child. But there is a long way to go to realize the 'real' integration of FP into MCH in Korea, unless there is a structural integration FP/MCH because a categorical FP is still first priority to reduce the rate of population growth for economic reasons but not yet for health/welfare reasons in practice. 3) There should be more financial allocation: (i) a midwife should be made available to help to promote the MCH program and coordinate services, (in) there should be a health sub·center director who can provide leadership training for managing the integrated program. There is a need for 'organizational support', if the decision of integration is made to obtain benefit from both FP & MCH. In other words, costs should be paid equally to both FP/MCH. The integration slogan itself, without the commitment of paying such costs, is powerless to advocate it. 4) Need of management training for middle level health personnel is more acute as the Government has already constructed 90 MCH centers attached to the County Health Center but without adequate manpower, facilities, and guidelines for integrating the work of both FP and MCH. 5) The local government still considers these MCH centers only as delivery centers to take care only of those visiting maternity cases. The MCH center should be a center for the managment of all pregnancies occurring in the community and the promotion of FP with a systematic and effective linkage of resources available in the county such as i.e. Village Health Worker, Community Health Practitioner, Health Sub-center Physicians & Health workers, Doctors and Midwives in MCH center, OBGY Specialists in clinics & hospitals as practiced by the Seosan project at primary health care level.

  • Today most developed countries provide modern medical care for most of the population. The rural area is the more neglected area in the medical and health field. In public health, the philosophy is that medical care for in maintenance of health is a basic right of man; it should not be discriminated against racial, environmental or financial situations. The deficiency of the medical care system, cultural bias, economic development, and ignorance of the residents about health care brought about the shortage of medical personnel and facilities on the rural areas. Moreover, medical students and physicians have been taught less about rural health care than about urban health care. Medical care, therefore, is insufficient in terms of health care personnel/and facilities in rural areas. Under such a situation, there is growing concern about the health problems among the rural population. The findings presented in this report are useful measures of the major health problems and even more important, as a guide to planning for improved medical care systems. It is hoped that findings from this study will be useful to those responsible for improving the delivery of health service for the rural population. Objectives: -to determine the health status of the residents in the rural areas. -to assess the rural population's needs in terms of health and medical care. -to make recommendations concerning improvement in the delivery of health and medical care for the rural population. Procedures: For the sampling design, the ideal would be to sample according to the proportion of the composition age-groups. As the health problems would be different by group, the sample was divided into 10 different age-groups. If the sample were allocated by proportion of composition of each age group, some age groups would be too small to estimate the health problem. The sample size of each age-group population was 100 people/age-groups. Personal interviews were conducted by specially trained medical students. The interviews dealt at length with current health status, medical care problems, utilization of medical services, medical cost paid for medical care and attitudes toward health. In addition, more information was gained from the public health field, including environmental sanitation, maternal and child health, family planning, tuberculosis control, and dental health. The sample Sample size was one fourth of total population: 1,438 The aged 10-14 years showed the largest number of 254 and the aged under one year was the smallest number of 81. Participation in examination Examination sessions usually were held in the morning every Tuesday, Wenesday, and Thursday for 3 hours at each session at the Namchun Health station. In general, the rate of participation in medical examination was low especially in ages between 10-19 years old. The highest rate of participation among are groups was the under one year age-group by 100 percent. The lowest use rate as low as 3% of those in the age-groups 10-19 years who are attending junior and senior high school in Taegu city so the time was not convenient for them to recieve examinations. Among the over 20 years old group, the rate of participation of female was higher than that of males. The results are as follows: A. Publie health problems Population: The number of pre-school age group who required child health was 724, among them infants numbered 96. Number of eligible women aged 15-44 years was 1,279, and women with husband who need maternal health numbered 700. The age-group of 65 years or older was 201 needed more health care and 65 of them had disabilities. (Table 2). Environmental sanitation: Seventy-nine percent of the residents relied upon well water as a primary source of dringking water. Ninety-three percent of the drinking water supply was rated as unfited quality for drinking. More than 90% of latrines were unhygienic, in structure design and sanitation (Table 15).

Number of discharged cases in the past accounted for 79 which showed 50% of active cases when discharged time. Rate of complete treatment among reasons of discharge in the past as low as 28%. There needs to be a follow up observation of the discharged cases (Table 18). Dental problems: More than 50% of the total population have at least one or more dental problems. (Table 19) B. Medical care problems Incidence rate: 1. In one month Incidence rate of medical care problems during one month was 19.6 percent. Among these health problems which required rest at home were 11.8 percent. The estimated number of patients in the total population is 1,206. The health problems reported most frequently in interviews during one month are: GI trouble, respiratory disease, neuralgia, skin disease, and communicable disease-in that order, The rate of health problems by age groups was highest in the 1-4 age group and in the 60 years or over age group, the lowest rate was the 10-14 year age group. In general, 0-29 year age group except the 1-4 year age group was low incidence rate. After 30 years old the rate of health problems increases gradually with aging. Eighty-three percent of health problems that occured during one month were solved by primary medical care procedures. Seventeen percent of health problems needed secondary care. Days rested at home because of illness during one month were 0.7 days per interviewee and 8days per patient and it accounts for 2,161 days for the total productive population in the area. (Table 20) 2. In a year The incidence rate of medical care problems during a year was 74.8%, among them health problems which required rest at home was 37 percent. Estimated number of patients in the total population during a year was 4,600. The health problems that occured most frequently among the interviewees during a year were: Cold (30%), GI trouble (18), respiratory disease (11), anemia (10), diarrhea (10), neuralgia (10), parasite disease (9), ENT (7), skin (7), headache (7), trauma (4), communicable disease (3), and circulatory disease (3) -in that order. The rate of health problems by age groups was highest in the infants group, thereafter the rate decreased gradually until the age 15-19 year age group which showed the lowest, and then the rate increased gradually with aging. Eighty-seven percent of health problems during a year were solved by primary medical care. Thirteen percent of them needed secondary medical care procedures. Days rested at home because of illness during a year were 16 days per interviewee and 44 days per patient and it accounted for 57,335 days lost among productive age group in the area (Table 21). Among those given medical examination, the conditions observed most frequently were respiratory disease, GI trouble, parasite disease, neuralgia, skin disease, trauma, tuberculosis, anemia, chronic obstructive lung disease, eye disorders-in that order (Table 22). The main health problems required secondary medical care are as fellows: (previous page).

  • 전자정부를 포함한 다양한 형태의 공공서비스가 제공됨에 따라 공공서비스 품질에 대한 국민의 요구 수준이 점점 높아지고 있다. 공공서비스의 품질을 높이기 위해서 공공서비스 품질에 대한 상시적 측정과 개선이 필요함에도 불구하고 전통적인 설문조사는 비용과 시간이 많이 소요되어 한계가 있다. 따라서 공공서비스에서 발생하는 데이터를 기반으로 원하는 시점에 언제라도 공공서비스의 품질을 빠르고 정확하게 측정할 수 있는 분석적 기법이 필요하다. 본 연구에서 공공서비스의 품질을 데이터 기반으로 분석하기 위해 N시의 건축 인허가 민원 서비스를 대상으로 프로세스 마이닝 기법을 이용하여 분석하였다. N시의 건축 인허가 민원 서비스는 분석에 필요한 데이터를 확보할 수 있고 공공서비스 품질관리를 통해 타 기관으로 확산 가능할 것으로 판단되었기 때문이다. 본 연구는 2014년 1월부터 2년 동안 N시에서 발생한 총 3678건의 건축 인허가 민원 서비스에 대해 프로세스 마이닝을 실시하여 프로세스 맵을 그리고 빈도가 높은 부서와 평균작업시간이 긴 부서를 파악하였다. 분석 결과에 따르면 특정 시점에 한 부서별로 업무가 몰리거나 상대적으로 업무가 적은 경우가 발생하였다. 또한 민원의 부하가 늘 경우 민원완료까지 걸리는 시간이 늘어날 것이라는 합리적인 의심을 하였으나 분석 결과 상관관계는 크게 없었다. 분석 결과에 따르면 민원완료까지 걸리는 시간은 당일처리에서 1년 146일까지 매우 다양하게 분포하였다. '하수처리과,' '수도과,' '도시디자인과,' '녹색성장과'의 상위 4개 부서의 누적빈도가 전체의 50%를 넘고 상위 9개 부서의 누적빈도가 70%를 넘어서는 등 빈도가 높은 부서는 한정적이며 부서 간 부하의 불균형이 심했다. 대부분의 민원 서비스는 서로 다른 다양한 패턴의 프로세스를 갖고 있었다. 본 연구의 결과를 활용하면 특정 시점에 민원의 부하가 큰 부서를 찾아내 부서 간 인력 배치를 탄력적으로 운영할 수 있을 것이다. 또한 민원 특성별 협의에 참여하는 부서의 패턴을 분석한 결과, 협의 부서 요청 시 자동화 혹은 추천에 활용할 수 있는 가능성이 보인다. 본 연구는 민원 서비스에 대한 프로세스 마이닝 분석을 통해 향후 공공서비스 품질 개선방향을 제시하는데 활용될 것으로 기대한다.

  • This study was conducted to assess the effectiveness of service by maternity aids concerning maternal and child health in improving simultaneously infant mortality, contraception and vital registration among expectant mothers in rural Korea, where there is less apportunity for maternal and child health care. It is unrealistic to expect to solve this problem in rural Korea through professional persons considering the situation of medical facilities and the socioeconomic condition of residents. So, we intended to adopt a system of services by maternity aids who were educated formally among indigenous women. After the women were trained in maternal and child health, contraception, and registration for a short period, they were assigned as a maternity aids to each village to help with various activities concerning maternal and child health, for example, registration of pregnant women, home visiting to check for complications, supplying of delivery kits, attendance at delivery, persuasion of contraception, and invitation for registration and so on. Mean-while, four researchers called on the maternity aids to collect materials concerning vital events, maternal child health, contraception and registration, and to give further instruction and supervision as the program proceeded. A. Changes of women's attitude by services of maternity aid. Now, we examined to what extent' such a service system to expectant mothers affected a change in attitude of women residing in the study area as compared to women of the control area. 1) In the birth and death places, there were no changes between last and present infants, in study or control area. 2) In regard to attendants at delivery, there were no changes except for a small percentage of attendance (8%) by maternity aid in study area. But, I expect that more maternity sids could be used as attendants at delivery if they would be trained further and if there was more explanation to the residents about such a service. 3) Considering the rate of utilization of sterilized delivery kit, I am sure that more than 90 percent would be used if the delivery kit were supplied in the proper time. There were significant differences in rates between the study and the control areas. 4) Taking into consideration the utilization rate of the clinic for prenatal care and well baby care, if suck facilities were installed, it would probably be well utilized. 5) In the contraception, the rate of approval was as high as 89 percent in study area as compared to 82 percent in the control area. 6) Considering the rate of pre-and post-partum acceptance on contraception were as much as 70 percent or more, if motivation to use contraception was given to them adequately, the government could reach the goals for family planning as planned. 7) In the vital registration, the rate of birth registration in the study area was some what improved compared to that of the control area, while the rate of death registration was not changed at all. Taking into account the fact that the rate of confirmation of vital events by maternity aids was remarkably high, if the registration system changed to a 'notification' system instead of formal registration ststem, it would be improved significantly compared to present system. B. Effect of the project Thus, with changes in the residents' attitude, was there a reduction in the infant death rate? 1) It is very difficult problem to compare the mortality of infants between last and present infants, because many women don't want to answer accurately about their dead children especially the infants that died within a few days after birth. In this study the data of present death comes from the maternity aides who followed up every pregnancy they had recorded to see what had happened. They seem to have very reliable information on what happened in first few weeks with follow up visitits to check out later changes. From these calculaton, when we compared the rate of infant death between last and present infant, there was remarkable reduction of death rate for present infant compare to that of last children, namely, the former was 30, while the latter 42. The figure is the lowest rate that I have ever heard. As the quality of data we could assess by comparing the causes of death. In the current death rate by communicable disease was much lower compare to the last child especially, tetanus cases and pneumonia. 2) Next, how many respondents used contraception after birth because of frequent contact with the maternity aid. In the registered cases, the respondents showed a tendency to practice contraception at an earlier age and with a small number of children. In a comparison of the rate of contraception between the study and the control area, the rate in the former was significantly higher than that of the latter. What is more, the proportion favoring smaller numbers of children and younger women rose in the study area as compared to the control area. 3) Regarding vital registration, though the rate of registration was gradually improved by efforts of maternity aid, it would be better to change the registration system. 4) In the crude birth rate, the rate in the study area was 22.2 while in the control area was 26.5. Natural increase rate showed 15.4 in the study area, while control area was 19.1. 5) In assessment of the efficiency of the maternity aids judging by the cost-effect viewpoint, the workers in the Medium area seemed to be more efficiency than those of other areas.

  • One of the most common feelings in everyday life is anger. Anger plays an important role in activating emotional energy and increasing intolerance when confronted with hardships, frustration and improper treatments. And it provides us with controlling interpersonal behavior, organizing internal, physiological, psychological process and various adaptive functions. If anger is not properly expressed, it brings about offensive attitude, leading to not only physical impairment but also anxiety in interpersonal relations and maladaptive to everyday life. For elementary school students, frequent quarrels, abusive words and defiant attitude toward adults are also caused by students' anger. Therefore, students' anger is one of the most difficult problems to be dealt with not only psychologically but also in elementary schools. In this respect, after investigating frequently experienced anger- inducing situations and inventing anger-inducing situation questionnaire, we postulated specific situations changing irrational belief into rational one. Based on these situations, we accounted for how to cope with anger inducing factors and change irrational belief into rational one, introducing several strategies needed to control anger, invented cognitive behavioral anger control program and tried to clarify the relationship between anger inducing experience and anger regulation ability. In order to derive usual anger-inducing situations, we made 180 students with fifth and sixth grade to record the reason why he/she got angry, mood, thought, behavior and result. Through this process, we could derive 47 situations bringing about anger and prepared anger-inducing situation questionnaire. It can be divided into 3 anger inducing situations by using factor analysis into 500 elementary students of fifth and sixth grade. Cognitive behavioral anger control program used in this study consists of 13 sessions. From first to fifth session, it is composed of 10 anger control methods to make students be aware of and control their anger. From sixth through thirteenth session, the relationship between irrational belief and anger inducing is introduced is focused on how irrational belief is changed into rational one. To examine the effects of the program, high anger students and the students lacking anger control are selected. Thirty students through pre-test using anger-inducing questionnaire and anger control ability questionnaire are taught the goals and procedures. Volunteer students and students with parents' consent allocated to experimental group (12 students) and the rest of the students are control group (12 students). Cognitive Behavioral Anger Control Program are applied every 50 minutes twice a week for 7 weeks and 4 weeks before and after this program, anger-inducing situation questionnaire and anger control ability questionnaire are practiced. Data collected in this study analyzed by SPSS and Kwakstat. In the middle of this program, quarterly reports and satisfaction measuratings were evaluated to examine whether there is verbal and non-verbal behavior change and students feel satisfied with the program. The results of this study are as follows: First, Cognitive-behavioral anger control program used in this study effectively reduced anger experience and lasted for 4 weeks. Second, cognitive behavioral anger control program increased students' ability to control anger inducing situations and also effective for 4 weeks. And its effect on verbal and non-verbal behaviour was very impressive Students come to realize that irrational belief is the cause of their anger and actively apply cognitive-behavioral anger control technique to themselves as well. Students became improved in their peer relations and felt confident in everyday life. The overall evaluation of this program can be listed as follows; "very satisfactory (91.67%)", "satisfactory (8.33%)", "very helpful (91.67%)", "helpful (8.33%). In this study we first investigated several anger-inducing situations and invented anger-inducing situation questionnaire and then applied cognitive behavioral anger control program in order to control their. anger and not to experience it. By creating workbooks and manuals this method can easily be used in school education settings.
