The aim of the study was to analyze the spatial characteristics of the main producing areas of nontimber forest products. We analyzed the spatial aggregations of the main producing area and their changes using the Moran's I index. We found that 45% of nontimber forest products were significanty spatially clustered. Additionally, in five major products, we observed that the main producing area has expanded and the degree of aggregation has also strengthened over the last ten years. The results of this study can be effectively used for forest policies, such as determining the location and size of the distribution centers of specific forest products.

작물은 그 종류에 따라서 지대에 따르는 적응성에 차가 있는 것인데 이것은 작물종류에 따라서 각각 적합한 자연적, 사회적인 조건이 다르기 때문이다. 현재 각지에 조성되어 있는 여러가지 종류의 작물의 주산지는 그 대부분이 오랜 시일에 걸쳐서 그 지대에 적응하므로 써 자연적으로 형성된 것이다. 근래 일부에서는 인위적으로 어떤 작물의 주산단지가 조성되는 경우도 있기는 하지만 이러한 경우에 있어서도 그 지대의 자연적, 사회적 조건이 그 작물의 재배에 적합할 때에 비로소 주산단지의 조성이 성공을 거두게 되는 것이다. (중략)

최근 경제수준 향상과 소자녀 가치관의 확립, 그리고 전국민 의료보험 실시 등으로 인하여 모자보건 대상자의 대부분은 민간 의료시설의 전문인력으로부터 서비스를 제공받게 되었고, 모자보건 수준도 급격히 향상, 1992년 시설분만율의 경우, 99%에 도달하였다. 이렇듯 의료시설 이용의 증가와 의료기술의 발전에도 불구하고, 영아사망율 및 모성사망율이 최근 몇년동안 같은 수준에 머무르고 있음은, 보다 질적인 관리측면으로 사업의 방향이 전환되어야 함을 의미하는데 이는 곧 공공성을 띠고 있는 모자보건사업을 국가가 관리하여야 할 필요성을 더욱 크게 한다. 공공부문에서는 취약대상을 위하여 민간 전문인력과의 유기적인 연계체계를 마련하여 계속적인 관리를 제공할 수 있도록 하고, 보건교육 강화를 위한 관련 홍보물(모자보건수첩 활용, 모유수유 권장, 제왕절개수술 지양 등)을 제작하며 신경아세포종 검사 등과 같은 새로운 예방사업 개발에 중점을 두어야 할 것이다. 또한 영유아관리는 저체중아 및 장애아에 대한 추구관리서비스까지 확대되어야 할 것이다. 현 우리나라 주산기구급이송체계는 응급의료체계내에서 이루어지고 있다고 볼 수 있는데 주산기관리를 위한 의료여건이 성숙되어 있지 못하고 있는데다(이 시기의 집중관리를 통하여 사망 및 장애아 예방이 가능) 관련 제도마저 취약하여 민간의료부문에서는 영아사망 및 모성사망을 낮추기 위해서는 이 부문에 대한 노력이 집중되어야 할 것이다. 첫째, 주산기학, 신생아학 전문인력의 훈련제도 확립파 주산기 관리시설의 지역적 적정분배(분만 2,000건에 1개 시설마련), 둘째, 집중적인 인력과 고가장비가 투입되는 주산기 의료활동 강화를 위한 관련 의료제도의 수정 및 보완, 세째, 질적관리가 매우 중시되는 고위험 신생아의 집중관리를 위한 '표준 의료관리지침서' 마련, 네째, 동 시설 및 관리에 준하여 주산기 의료시설에 대한 감독 및 감시기능 강화를 위한 제도적 장치가 마련되어야 할 것이다.

In this study, I aimed to suggest political data on the plantation of chestnut trees given the local features by conducting an analysis on the economic efficiency of the plantation of chestnut trees aimed at chestnut tree plantation farmhouses (total 67 farmhouses) in Chungbuk, Chungnam, Jeonbuk, Jeonnam and Gyeongnam, which are the chief producing place in Korea. As a result, the central area (Chungbuk, Chungnam) was proven to post 2.7 times as many as the average total income, 3.9 times as many as income, and 12.1 times as many as net income per ha when compared with those in the southern area (Jeonnam, Gyeongnam). That is, the southern area demonstrated a very low economic efficiency on the plantation of chestnut trees compared with that of the central area, and this was caused by the reduction of chestnut production and the degradation of chestnut quality due to the aging of chestnut trees. Therefore, it is imperative to consistently renovate aged chestnut orchards and manage them in the southern area.

Purpose : Perinatal hepatitis B viral infection is decreasing; however, 10% of babies to HBeAg positive mothers still become chronic carriers despite perinatal prophylaxis. Although, the cause of prophylaxis failure is still unclear, an importance of maternal HBV-DNA level at the delivery time has been suggested. This study was established to certify if it would be a useful predictable factor for the outcome of perinatal prophylaxis. Methods : Twenty-nine HBeAg positive mothers whose babies had known outcomes of prophylaxis were selected. To determine the amount of maternal HBV-DNA, a quantitative PCR was performed with the WHO International Standard for HBV DNA NAT assays. Results : The mean logarithm HBV-DNA level of mothers with failed outcomes was significantly higher than that of mothers with succeessful outcomes (7.99 vs. 6.72, P=0.015). The predictable maternal HBV-DNA cut-off level to prophylaxis outcome was $2.83{\times}10^7copies/mL$ (100 pg/mL). None out of the case 16 (0%) who had below this level, and 5 out of 13 (38.5%) who had above this level of maternal HBV-DNA failed in perinatal prophylaxis. Conclusion : Mothers with higher levels of HBV-DNA at delivery time would be prone to a worse outcome of prophylaxis using the conventional approach. Perinatal prophylaxis failure rate can be reduced, if we try to introduce more potent prophylactic treatment into the cases with this risk factor.

우리나라 고구마 재배면적은 2000년 16천㏊ 내외로 재배되고 있다. 국내 재배 주산지는 전남 해남, 여천, 경기 여주 순으로 주산지 지역특화작목으로 부상함에 따라 우리나라 전체 재배면적의 약 25%를 차지하고 있다. 이들 주산지에서 재배되는 고구마는 대부분 식용으로 이용되면, 가장 선호하는 고구마는 모양이 둥글고 크기는 100-200g 정도이며, 특히 최근 세 척 고구마의 유통이 증가함에 따라 껍질이 벗겨지지 않은 자색이나 홍색의 고구마를 선호하고 있어 수확 시 껍질이 벗겨지지 않게 수확할 수 있는 수확기가 절실히 요구되고 있다.

The causes and problems underlying deaths in perinatal period are often similar and might be expected to yield to same type of preventive measures. This is one of the reasons for attempting to develop a reporting of perinatal mortality and its related matters. This study aims at figuring out the biologic risk factors onto the perinatal death. Considering stillbirth and early neonatal mortality separately, considerable associations between stillbirth and reproductive history of women, are observed, ana it is found that prematurity is the the far most important factor in the early neonatal mortality.

Garlic and onion are grown in major cultivation regions that depend on the crop condition and the meteorology of the production area. Therefore, when yields are to be predicted, it is reasonable to use a statistical model in which both the crop and the meteorological elements are considered. In this paper, using a multiple linear regression model, we predicted garlic and onion yields in major cultivation regions. We used the MODIS NDVI that reflects the crop conditions, and six meteorological elements for 7 major cultivation regions from 2006 to 2015. The multiple linear regression models were suggested by using stepwise regression in the extraction of independent variables. As a result, the MODIS NDVI in February was chosen the significant independent variable of the garlic and onion yield prediction model. In the case of meteorological elements, the garlic yield prediction model were the mean temperature (March), the rainfall (November, March), the relative humidity (April), and the duration time of sunshine (April, May). Also, the rainfall (November), the duration time of sunshine (January), the relative humidity (April), and the minimum temperature (June) were chosen among the variables as the significant meteorological elements of the onion yield prediction model. MODIS NDVI and meteorological elements in the model explain 84.4%, 75.9% of the garlic and onion with a root mean square error (RMSE) of 42.57 kg/10a, 340.29 kg/10a. These lead to the result that the characteristics of variations in garlic and onion growth according to MODIS NDVI and other meteorological elements were well reflected in the model.

Fish eggs and larvae in the western waters of Korea are surveyed during the periods from February to August in 1982. Six species of eggs and forty-two species of larvae are occurred in the survey area. The dominant species occurred during the study periods are Ammodytes personatus, Enedrias sp., Engraulis japonica, Callionymus sp., Gobiidae, etc. Major spawning month and ground of each species are estimated from the data, i.e., occurrence month and abundance of eggs and larvae by survey month and area, as well as the optimum water temperature and salinity for spawning.
