도농복합시는 도시지역과 농촌지역이 병존하는 독특한 공간구조를 갖고 있다. 따라서 도농복합시의 농촌과소화에 대응하기 위해서는 기존 주민의 이탈을 방지할 수 있는 다양한 정책적 지원 방안을 모색할 필요가 있다. 이러한 맥락에서 본 연구에서는 '2017년 춘천시 사회조사'를 이용해 도농복합시 농촌지역 과소화 대응 방안으로 기존 거주민의 지속적인 거주의향에 영향을 미치는 요인을 분석하였다. 일반적으로 지역정체성은 내생적으로 결정되기 때문에 본 연구에서는 이러한 지역정체성과 거주의향과의 내생적 관계를 고려하여 연립 이변량 순위 프로빗 모델을 이용하였다. 분석결과, 도농복합시에 대해 지역정체성이 강할수록 지역내 거주의향이 높아지는 것으로 분석되었다. 가구주의 연령과 거주기간이 길수록, 일 여가생활 거주에 대해 만족할수록 지역정체성이 높다. 그리고 의료서비스에 대해 만족할수록, 종사하는 일에 만족할수록 거주의향이 높다. 따라서 도농복합시 농촌지역 거주민들의 생활서비스 수요를 파악 후 적재 적시 적절한 생활서비스를 공급할 수 있는 정책적 지원이 필요하다. 특히 도농복합시의 경우 의료서비스는 지역정체성에는 통계적으로 유의미한 영향을 미치지 않지만, 거주의향에는 유의미한 영향을 미치고 있다. 따라서 의료시설에 쉽게 접근하여 사용할 수 있는 시스템 구축이 필요하다.

The study compared the fatty acid profiles of 3 muscles (Longissimus dorsi, LD, Triceps brachii, TB and Semimembranosus, SM) obtained from Korean Hanwoo (18 steers, 24 months old) and Australian Angus beef (18 steers, 24 months old) and assessed their role in sensory perception. The samples of each carcass were prepared in the same manner, and cooked both as traditional grilled steaks and Korean BBQ style. A total of 720 Korean sensory panelists evaluated the beef samples for tenderness, juiciness, flavor, and overall liking. Oleic acid (18:1) was significantly (p<0.05) higher in TB than that in LD and SM. The essential linoleic acid (C18:2) was significantly (p<0.05) higher in TB and SM than that in LD. For LD muscle, the proportion of saturated fatty acids was significantly (p<0.05) highest, while that of polyunsaturated fatty acids was lowest among the three muscles. Australian Angus beef had significantly (p<0.05) higher n-3 PUFA than that of the Korean Hanwoo for the three muscles, while the latter contained significantly (p<0.05) higher n-6 PUFA than that of the former. The clustering analysis showed that there a was significant difference in fatty acids such as C16:0, C16:1n7, C18:0, C18:2n6, C18:3n3, C20:3n6, C20:4n6, C22:4n6, and C22:5n3 for sensory perception (tenderness, juiciness, flavor and overall likeness) of the beef from two origins (p<0.05) among three clusters. Especially, C14:0 had a significant effect on sensory perception only for Korean Hanwoo beef; while C20:5n3 had a significant (p<0.05) effect only for Australian Angus beef based on clustering with the sensory variables.

A survey was made with regard to understanding attitude and practical use of modern and traditional methods of health care in a rural village with 742 inhabitants which comes under one of the whole three types of Korean rural community, to find out the following facts. 1. Among the five types of health-care given, the most understood, chosen and used one was the doctor followed next by pharmacy and continually herb doctor, folkways method, shamanistic treatment; the last shown method was principally chosen to use by only one among 139 housewives as respondants available, 2. Between herb medicine and folkways method of care, the former was more relief upon than the latter while the latter was more used than the former, seemingly because of relative low cast of the latter. 3. A considerable part of those who mainly used the doctor or pharmacy also used herb doctor or folkways care； modern and traditional care methods coexisted in the pertaining community. 4. Nearly all of the respondants ware, reasonably, aware of effectiveness of modern types of health-care; but, at the same time, more than a half of them had a positive attitude towards traditional method as well. 5, On the whole, the respondants made a distinction between traditional health-care methods and shamanism, regarding the latter as ineffective. 6. The result hints that it would be desirable for health-care professionals to inquire into traditional methods of health-care with a view to being more acquainted with rural residents and so raising their use of services by experts. 7. It should be added that the results of this piece of study may have a general significance only within those communities which shares the same socio-cultural background and characteristic of the surveyed one.

새로운 침투성 살균제 EL-291 (5-Methyl-1,2,4-tri-azolo(3, 4-b) benzothiazole, $75\%$ 수화제)의 벼 도열병 방제효과를 구명코저 온실검정과 포장시험을 실시하였다. EL-291은 병원균 접종후 살포보다 접종전 살포시 효과가 뚜렷하여 현저한 예방효과를 나타냈으나 가스가민, 벤레이트 상반된 반응을 나타내어 치료제로서 작용했다. 잎 도열병방제효과는 EL-291과 가스가민, 벤레이트간에 차이가 없었으나 이들 약제의 2회 살포에 비해 EL-291은 근침처리 또는 1회 살포한 것이므로 사용이 간편하고 경제적이라 할 수 있겠다. 이삭도열병에서도 1회 살포한 EL-291이 2회 살포한 가스가민, 벤레이트보다 월등히 효과가 좋았으며 수량도 EL-291 처리구가 더 많았다.

The aim of this study was to relate personal data, socio-cultural and environmental characteristics, and the presence of symptoms/signs with the frequencies of Giardia spp. and Blastocystis hominis among a rural population in Buenos Aires Province, Argentina. Of the surveyed population (350), 3.7% were infected with only Giardia spp. or 22.9% with B. hominis, and 2.3% were infected with both protozoa. The frequency of infection according to sex; 6.1% of males were infected and 1.6% of females by Giardia spp., 26.7% and 19.5% by B. hominis, and 2.4% and 2.2% by both parasites, respectively. Giardia spp. was detected in only three adults (over 14 years), but B. hominis was more frequent in adults than in children. The prevalences of these protozoa in this community are lower than those reported by other Argentinean studies, which is probably associated with the low density of the studied population ($5.95{\;}inhab/\textrm{km}^2$). Statistical analysis revealed that a male sex, flooding of the home, the use of a latrine, and an abdominal pain were correlated with the presence of these parasites, which indicate the importance of these factors in rural communities.

In legumes, soyasaponins, one of triterpenoid saponins, are major components of secondary metabolites with a more diverse array of bioactive chemicals. Although the biosynthetic pathway of soyasaponins has been largely studied in soybean, the study on the soyasaponin contents and biosynthesis-related gene expression in pea (Pisum sativum L.) is poorly understood. Here, we found the accumulation of only soyasaponin Bb component in the sprouts of two Korean domestic pea cultivars (Dachung and Sachul). This pattern was consistent with our observation that increased expression of PsUGT73P2 and PsUGT91H4 genes, but not PsCYP72A69, could be responsible for biosynthesis of only soyasaponin Bb in pea by examining their gene expression. However, gradual accumulation of soyasaponin Bb at developmental stages was not consistent with the expression of PsUGT73P2 and PsUGT91H4, suggesting that the changes of their protein activities may affect the accumulation patterns of soyasaponin Bb. We also revealed that the increased expression levels of PsUGT73P2 and PsUGT91H4 during light to dark transition led to increase of soyasaponin Bb contents. Collectively, our results provided a molecular basis of metabolic engineering for enhancing useful soyasaponin Bb metabolites in Korean domestic pea cultivars.

This study was conducted to investigate the impact of harvest time on yield and seed quality in purple seed coat peanut. Compared to the average Virginia peanut variety, 'Heuksaeng', purple peanut variety has been reported to experience yield loss and reduced seed quality under delayed harvest. We examined the yield components and seed quality at different harvest times from 70 to 110 days after flowering (DAF), with harvesting occurring at intervals of 10 days. The number of mature pods per plant reached a maximum of 51.0 at 80 DAF, and average pod and seed yield peaked at 80 DAF with values of 5,229 and 3,532 kg per ha, respectively. Seed quality drastically decreased after 100 DAF, and the concentrations of two major anthocyanin compounds were significantly lower under delayed harvest. The antioxidative activities of DPPH and ABTS decreased to only 69 and 83% of their maximum values at 110 DAF. On the basis of these results, we recommend that 'Heuksaeng' is harvested approximately 10 to 15 days earlier that average Virginia-type cultivars to obtain the highest yield while minimizing the deterioration of seed quality.

Resilience is the capacity to maintain essential services under a range of circumstances from normal to extreme. It is achieved through the ability of assets, networks, systems and management to anticipate, absorb and recover from disturbance. It requires adaptive capacity in respect of current and future risks and uncertainties as well as experience to date. The agricultural infrastructures with high resilience can not only reduce the size of the disaster relatively, but also minimize the loss by reducing the time required for recovery. This study aims to evaluate the most suitable drought countermeasures with the analysis of various resilience indices by predicting future agricultural water shortage under land use and climate change scenarios for agricultural areas in Jeju Island. The results showed that the permanent countermeasure is suitable than the temporary countermeasures as drought size and the cost required for recovery increase. Wide-area water supply system, which is a kind of water grid system, is identified as the most advantageous among countermeasures. It is recommended to evaluate the capability of agricultural infrastructure against drought with the various Resilience Indices for reliable assessment of long-term effect.

In order to revitalize rural areas fundamentally through multifunctional utilization of their resources, it should be necessary to prepare the rational development plan to the areal characteristics and conditions, and the first priority of its planning works should be given to spatial planning. The space syntax method, a powerful objective and quantitative analysis tool on the relationship between social and spatial characteristics, was introduced in this study. Five Comprehensive Rural Clustered Villages Development Areas in the Jeonnam-province were selected as case study areas, of which total area's and included villages' spatial variables were measured and analyzed. Rural villages analyzed in this study have the spatial structure badly systematized and much complicated, which results from low integration and deep spatial depth of them. And, by virtue of relatively many axial lines, there should be few differences between villages in terms of local integration, connectivity and control, while being significant difference in terms of global integration showing the whole areal characteristics. Intelligibility, the correlation coefficient between connectivity(local variable) and integration(global one) is low, which means that the spatial structure of the study areas is difficult for visitors to understand the area or village well. Spatial configuration analysis results in the case study areas showed that each development area has a unique spatial structure and is differentiated in terms of not only local spatial variables but also global spatial variables. Therefore, global and local characteristics should be considered in spatial analysis of development areas.
