도토리묵 제조용 조전분의 품질 특성을 규명하기 위한 기초연구 목적으로 수입 원산지(국내산, 북한산, 중국산)별로 일반성분, pH 및 산도, 무기질 및 당 조성, 색도, 총 페놀함량, 항산화 활성 등을 조사하였다. 일반성분에서는 북한산의 경우 수분함량은 적고 탄수화물, 조지방, 조단백이 국내산이나 중국산보다 높았다. pH는 3개 시료에서 유사하였으며 산도는 북한산이 0.021%로 중국산이나 국내산보다 다소 높게 나타났다. 이러한 산도의 유의성 차이는 채취년도 및 보관온도, 보관기간 등에 의한 수분량 감소, 성분변화 등에 기인한 것으로 생각된다. 특히 원료별 유통경로 및 보관온도, 보관기간에 차이가 있었다. 무기질의 경우 국내산은 Na 함량이 적고(4.52 mg/100 g), Mg(14.11 mg/100 g)과 Ca(136.84 mg/100 g) 함량이 높았으며, 북한산은 K(94.87 mg/100 g)과 P(18.17 mg/100 g)이, 중국산은 Fe(4.55 mg/100 g)과 Zn(1.07 mg/100 g)이 상대적으로 높았다. 당 성분의 경우 포도당 함량은 국내산(187 mg/100 g)이, 자당은 중국산(80 mg/100 g)이 높았다. 색도에서는 명도값(L)이 북한산에서 59.89로 가장 낮은 값을 보였으며, 국내산 64.60, 중국산 64.48으로 차이를 보였다. 적색도(a)와 황색도(b)에서는 북한산이 2.55, 13.15로 가장 낮은 값을 보인 반면, 국내산과 중국산은 유의적인 차이가 없었다. 총 페놀 함량에서는 북한산이 0.009 mg/mL로 가장 높았으며 다음으로 중국산 0.006 mg/mL, 국내산 0.004 mg/mL 순으로 나타났다. DPPH radical 소거능의 경우 $IC_{50}$ 값에서 북한산이 47.0 mg/mL로 가장 높았고 중국산 73.7 mg/mL, 국내산 86.8 mg/mL로 차이를 보였다. 또한 hydroxyl radical 소거능에서도 북한산의 $IC_{50}$ 값이 0.038 mg/mL로 가장 높은 활성을 나타냈으며, 그 다음으로 중국산 0.041 mg/mL, 국내산 0.044 mg/mL 순이었다. 따라서 이들 수입 원산지별 도토리묵 제조용 조전분에 대한 분석 결과 성분별 함량 차이는 존재하였으며 어느 시료에서 전체 품질이 우수하다고 보기는 어려웠다. 그러므로 현재 수입되고 있는 북한산 중국산 도토리묵 제조용 조전분에 대한 원산지별 다른 영양성분을 고려하여 생산하고자 하는 특정 가공식품의 이용을 검토하여 그 특성에 맞게 적용하려는 노력이 필요할 것이다.

It is widely recognized that primary health care in the community is one of the most important and effective health measures in these days. However, it is reality that unsatisfactory health care system, ineffective utilization of health care by the community people in the rural area are hampering better understanding for primary health care. Therefore promoting health for the rural people and increasing understanding about primary health care, the baseline survey in the community focused in examination for safe community water supply was carried out. The survey was conducted through August 25-31, 1986 in order to find out health problems and relevant factors and to define the demographic characteristics of $^*$Sanpuk village, Kumsa-Myun, Yuju-Gun, Kyunggi-Do, Korea. Household survey was carried out for every home by trained interviewers. The major results are found out as follows : 1) 84.2%(400 houses) of total households were surveyed because 15.8%(75 houses) were unable to survey due to either refusal against interview or absence of family. These 400 households were composed of 1,697 residents(male:830, female 867). Educational level of respondents showed 34.1% as elementary school graduated. Religion distribution showed Buddism(23.8%) as the most dominant. 50.7% of respondents married in the area. 2) Most households(91.5%) have lived in their own house in Sanpuk area. Average family size showed 4.3. More than half of residents(64.2%) have used public supplied water tap. Only 1.5% of the households had a flush toliet. The rest of households have still used primitive insanitary latrines. 3) 32.5% of residents have used gas burner for cooking and for heating in the house, and the coal briquet were used for boiler. Lack of convenient public transportation was the chief complaint for their day life. 4) Each household occupied 1,990 pyungs of rice paddy and 1,170 pyungs of ordinary field in average. Beside farming products, mushroom was the highest product. 5) Sixth percent of households in the survey area regularly participated in community meeting one hand and on the other hand 39.5% never participated. Most of respondents closely contacted with their neighbours and they seemed very friendly each other. 6) The prevalence rate of illness and injury during recent 15 days showed 48.3 per 1,000. The prevalence rate of chronic illnesses during the past one year showed 74 per 1,000. Injury and accident lead the higher portion(22.0%) in the former and in the latter pain(arthritis, back-pain) showed 27.0% as the dominant sickness. 87.8% of the ill residents in the former received medical treatment. As the most frequently utilized medical facility, the clinic or hospital were counted. Among the residents suffering from chronic illnesses, 77.3% in Sanpuk area get some kind of medical treatments and they rarely utilized the clinic or hospital. The reason why the patient did not receive any medical care was found out the fact that symptoms of illness was light or mild and economic problems was serious. 7) Average age of marriage showed 21.6 years old in the women and the average duration of marital period was shown for 15.1 years. The married woman in reproductive age in Sanpuk area had experienced pregnancies 4 times in the aver-age including 0.7 time of pregnancy in average were interrupted by induced abortion and 0.3 time by spontaneous abortion respectively. The practicing rate of the family planning of the married woman during reproductive ages showed 70.7% and the tuballigation was found out as the most frequently used contraceptives. 8) Among woman who has children under 2 years old, 70.0% had received the prenatal care for the last pregnancy. However, the average number of prenatal care visitis per woman showed 3.3 times. Fifty-two % of woman who received the postnatal care for the last delivery showed only 37.5%. 9) Immunization rate of the children under 2 years old showed relatively high and looked successful. The breast feeding for these children showed dominantly in the most. Most of the mothers in Sanpuk area had started the supplementary diet during weaning period of their infants of 6th and 7th month after birth. * : Sanpuk area is a demstration area for community development which has been supported by the Community Development Foundation during the part 10 years. The village is relatively closer to urban area such as Seoul, However, it has a similar characteristics shown as a remote village because of geographical location and inconvenient transportation at present.

An important role of community health nurses in health centers is to solve community health problems found through data collection methodology which has been used to identify the health needs of the community, diagnose the health problems and to plan health programs suitable for the health problems. Also community health nurses must be prepared to know the community health needs and to participate in the planning process. Since 1956 when the health center law was established, community health nurses have really implemented only the services which the government has asked them to do. This has kept them busy enough. But these days as society is in rapid change, community health nurses should have the flexibility to deal with the social change and demands that are unique to their community each which has different health needs and demands. So community health nurses need to identify what community health problems exist in their particular communities. The purposes of this study were as follows. 1) To explore the suitability of the health programs which the government has asked the community health nurses to do for their own communities and if these programs are not suitable, to explore the reasons why. 2) To explore the degree to which the community health nurses have the ability to identify health problems in their own communities and activate the community diagnostic process. 3) To identify the degree that the community health nurses have the ability to implement plans related to community diagnosis. 4) To find out how much data related to community health problems, the community health nurses have and how they are utilizing it. 5) To measure the community health nurses self-confidence concerning diagnostic activities for community health. The study subjects were 454 Community Health Nurses working in Health Centers in Seoul, Korea. The period of data collection was 6 days(Nov. 9th 1991-Nov. 15th 1991). A questionnaire used for data collection was composed of three different items; general characteristics, community health diagnostic activities and self-confidence in performing diagnostic activities. The results of the study are as follows. First, over one third of the respondents replied that the government required activities for their communities are not appropriate. Of these activities the most frequent reply $(51.2\%)$ indicated that many of the activities in the community were inappropriate to the actual situation. Further, $25\%$ of the replies indicated that many activities were only administratively oriented and as such not appropriate. Second, $49.8\%$ of the respondents replied that they had done general assessments and had a general idea of the health problems of their community. Effective solutions to health problems could be found with an increase in health personnel and management ability according to $41.5\%$ of the respondents. Third, to the question as to whether they had ever independently implemented a plan towards solving community diagnosed problems, $52\%$ of nurses replied 'never', $40\%$ 'occasionally' but only $7.5\%$ replied that they did it frequently. Actually there was very little done even in the basic work of collecting the necessary data. Fourth, when asked how much of basic information they had collected that might be used in community diagnosis activity, of 26 items in 5 areas, there was hardly one for which complete data had been collected. Fifteen percent did have data on the geographical aspects of their area, housing distribution and types of housing, while $17.8\%$ knew the frequency with which the health center was used. Concerning community resources, even with a list of community resources, only $12.3\%$ had data on any of these resources, and this data was incomplete. Further, information about social work institutions, and facilities was also incomplete, only $14.2\%$ of the respondents had any data and even it was incomplete; that is, in general, the nurses did not have this information. Fifth, concerning the confidence of the community health nurse in their ability to carry out community diagnoses activities, $60\%$ replied that they were very or at least nominally confident, indicating that although they were not doing community diagnostic activities they felt they could do so, as they were carrying out home visits and program planning as part of their official duties. The following recommendations are made based on the results of this study. First; since the community health nurses have a high perception of the need for community diagnostic activities and. high confidence in their ability to carry out this activity and high percentage of respondents replied that with a little training they could do this even better it is recommended that community diagnostic activity training be included in the continuing education program for community health nurses. Second, in order for the Community Health Nurses to successfully solve the health problems of their respective community they reported to a need to increase the number of health personnel, improve the facilities and the system of managing their work. Considering this, it is recommended that ways be sought to remedy these deficits.

This study analyzed the services as operated by the Child Health Telephone Service Center. The Center is a toll free service operated as part of the community services of the Korean Academic Society of Child Health Nursing. The aim of the study was to describe the concerns of child caregivers regarding child health care as discussed during telephone counseling. Specific objectives were as follows: 1. To analyze the activities of the Center. 2. To describe the characteristics of caregivers who made phone calls for counseling services and also the characteristics of their children. 3. To analyze the content of the counseling sessions. 4. To analyze counseling content according to the characteristics of the caregivers and their children. Data used for the study were obtained from the counseling records for the period from Sept. to Dec. 1999, as kept by the three counselors at the Center. The total number of calls was 8,261 and that consisted of 15,150 questions. The total questions were merged into 13,236 by eliminating those questions which overlapped or were of similar content. The final 13,236 questions were used for the final analyses. Almost of the callers (98.4％) were mothers. Among them 89.6％ were between 25 and 35 years of age. Geographical distribution of the callers covered the whole nation. The largest numbers who made the calls were from the Seoul metropolitan area (36％), followed by 28％ from Kyung Gi Province, and 20％ were from the Kyung Sang area. Among 8,261 callers, 72.8％ were first users. Sex of the babies and children in question for counseling was about even for males and females and ages ranged from one month to six years. The largest group (62.5％) was the less than six month age group. The finalized 13,236 questions/problems were categorized into 11 problem areas. They were in order of frequency, physical problems, feedings and nutrient concerns, information on child rearing, growth and development, guidance on utilization of child care facilities, elimination problems, sleeping concerns, immunization related concerns, behavior problems, injury and accidents, and safety measures. The most frequent problems for counseling were physical signs and symptoms (27.3％), followed by feeding and nutrients, information on child rearing, and growth and development. Of physical problems, abnormal gastrointestinal signs and symptoms were the most frequent concern and skin problems were next at 25％ and 23.3％ respectively. Loose bowels, vomiting and constipation were the most frequent gastrointestinal problems. Atopic dermatitis had the highest frequency at 53.3％ with diaper rash being the second highest among the skin problems. About 80％ of the growth and developmental category were physical development concerns related to physiological, body growth, and motor and sensory development. This study constitutes the activity report for the first year of the Center. The findings correspond with literature reports on child health problems and parents educational needs. One recommendation from this study is that since the services of the Center are carried out only by telephone, the psychology of the counselees and the counselor relationship must be considered for better services.

The purposes of this study were to investigate and understand the present status of various types of "deserts", such as sand desert, gravel desert, rock desert, earth desert, salt desert, desert, rocky desert, gobi desert, sandy desert, clay desert, etc., and the general countermeasures for the combating "desertification" "desertization", and to develop the technologies on the revegetation and restoration for the combating desertification in China. The methods of this study were mainly composed of field surveys on the several experimental sites and research institutes related to combating desertification in China, and examinations on the various technologies for the combating desertification at the Daxing Experimental Station of Beijing Forestry University. The conclusion from this study may be summarized as follows; 1. Status and tendency of desertification in China : China is one of the countries seriously threatened by desertification. Desertification affected areas in China are mainly distributed in arid, semi-arid and dry sub-humid areas in China, covering the most regions of the Northeast China (eastern region of Inner-Mongolia), the northern part of the North China (middle and western region of Inner-Mongolia, Shaanxi, Ningsha, Gansu) and the western part of the Northwest China (Xinzang, Qinghai, Xizang). The total area affected by desertification in China is approximately 2.622 million $km^2$. It covers 27.3% of the total territory of China. Until recently, it is estimated that the annual spreading ratio of desertification in China is 2,460 $km^2$. Therefore, desertification is mostly serious problems facing to the Chinese people. 2. The causes and environmental effect of desertification : The desertification in China is mainly caused by compound factors, including natural condition and human activities. In China, the desertification is started by the decrease of precipitation, continuous dry and drought, strong wind, wind and water erosion, land degradation and loss of natural vegetation caused by climate variation, and accelerated by the human activities, such as over-cultivating, over-grazing, over-cutting of woods, irrational use of water resources. Because desertification has affected the geographical features, soil nutrients contents, salinity, vegetation coverage and the functions of ecosystem, the environmental deteriorations in the desertification affected areas are very seriously. 3. The fundamental strategies of combating desertification in China are the increase of education and awareness of people through various mass media, the revision of laws to guarantee operation of Desertification Combating Law and to improve many relating laws and regulations, the application of advanced technologies and training of experts, the establishment of discriminative policies, and increasing arrangement of budget-investment, and so on. China, as a signed country in UNCCD, has made efforts for the combating desertification. Korea is also signed country in UNCCD, so we should play an important role in the desertification combating projects of China for the northest asia and global environmental conservation as well as environmental conservation of Korea.

본 연구에서는 FT-IR 스펙트럼 분석을 통해 한국에서 자생하는 Zoysia 속인 들잔디(Zoysia japonica)와 갯잔디(Zoysia sinica)의 전세포추출 시료로부터 대사체 수준에서 신속한 식별체계를 확립하고자 하였다. 이를 위해 기준라인으로 분자마커를 이용해 동정이 완료된 들잔디와 갯잔디 시료를 FT-IR 분석에 사용하였으며, 제주도와 전라도에서 수집된 미동정 잔디들을 기준라인과 비교분석하기 위해 FT-IR 분석에 사용하였다. 기준라인 들잔디와 갯잔디 시료로부터 확보된 FT-IR 스펙트럼 데이터의 PCA (principal component analysis)와 PLS-DA (partial least square discriminant analysis) 분석 결과 각 기준라인은 들잔디 및 갯잔디 종에 따라 뚜렷하게 식별되었다. 들잔디와 갯잔디 시료 사이에서 가장 큰 PC loading value값을 보인 부위는 $1,100{\sim}950cm^{-1}$였다. 이 부위는 carbohydrates 계열의 화합물들의 질적, 양적 정보를 반영하는 부위로 이 계열의 화합물의 양적, 질적 차이가 들잔디, 갯잔디의 대사체 수준 구분에 중요한 역할을 하고 있음을 알 수 있었다. 기준라인 들잔디와 갯잔디 시료집단에 미동정된 잔디 시료 집단을 추가하여 PCA와 PLS-DA 분석한 결과, 일차적으로 들잔디와 갯잔디로 구분이 이루어졌으며 미동정 집단은 모두 들잔디 그룹내에 분포하였다. 특히, HCA (hierarchical clustering analysis) dendrogram 분석 결과에서 동정 및 미동정 들잔디 시료들은 모두 수집지 특성에 따라 국내 국립공원의 고산지대와 국내 섬지역 해안가의 저지대로 별도의 소그룹을 형성하였다. 따라서, 본 연구 결과에서 확립된 FT-IR 스펙트럼 분석법은 한국 전역에 자생하는 들잔디와 갯잔디의 신속한 종 식별뿐만 아니라 수집 지역의 특성에 따라 대사체 수준에서의 유연관계를 규명하는데 활용 가능할 것으로 기대된다.
