Since 1982, schools have been closed down by urbanization in rural areas. 3,386 schools had been closed down by March 2010. The average 300 schools was closed down every year. 55.7% closed schools were sold, 14.5% closed schools were rented. 6.3% closed schools have been utilized as education facilities. First, the closed school should be utilized as education facilities. And it should be utilized as public facilities as well as welfare facilities for local residents. This paper presents a case of the welfare facility remodeled using Don-Yi middle school in Okcheon-Gun, Chungcheongbuk-Do and propose the unit care composition. The main contents is composed of posts, beams floors, stairs. Masonry infill walls and windows ware improved. Corridors were placed. A classroom were divided into 2 rooms with the Korean traditional heating system(on-dol) for four. Other conveniences were designed for a cafeteria, recreation, a restroom as space required. It is effective to utilize the closed school that has magnificent views and orientation, space construction. The Unit-care system is proposed by 4 types developments.

We investigated the zircon U-Pb ages of the metapelites from the Sungjeon-myeon Gangjin-gun, the southwestern Ogcheon belt, to provide geochronological constraints for the depositional age as well as the distribution of Late Paleozoic formation. Data from the detrital zircons are mostly concordant, yielding four major age groups: (1) Neoarchean (~2.5 Ga); (2) Paleoproterozoic (~1.86 Ga, Statherian); (3) Middle Devonian(~390 Ma); and (4) Late Paleozoic (~322 Ma, Serpukhobian). The youngest zircon age gives a weighted mean $^{206}Pb/^{238}U$ age of $322{\pm}4.8$ Ma (n=16, MSWD=4.9), indicating deposition age of Early Carboniferous(Serpukhobian) or after. Therefore, the metapelites is considered to be the lowest Formation of the late Paleozoic Pyeongan Supergroup correlated with the Manhang Formation of the Samcheock coal fields and the Oeumri Formation(the Middle to Late Carboniferous) of the Hwasun coal field.

This study was conducted to identify behavioral characteristics of salty food intake according to saline sensitivity of adults living in a rural area. Anthropometry and blood pressure were measured and salt intake-related dietary behavior was surveyed by questionnaires through interviews with 402 subjects aged ${\geq}$ 40 years in Chungcheongbuk-Do, Korea. The percentages of overweight and obese among the subjects were 37.8% and 3.8% respectively. Mean blood pressure of the subjects was in the normal range, but the distribution of subjects who were normotensive, high normal, and hypertensive was 48.7%, 17.7%, and 33.6% respectively. Approximately 27% of all subjects habitually consumed salty food, which was the smallest group, followed by 38.1% normal and 35.1% not-salty food. However, 34.6% of the eldest group of ${\geq}$ 65 years consumed salty food. The saline insensitive group showed a higher percentage of irregular meals, overeating, speed-eating, an unbalanced diet, a preference for fried food, and habitual intake of salty foods. These subjects recognized the risk for eating salty food, but they lacked the will to reduce their salty food intake. Compared to spouses and family members, experts such as doctors, nurses, and dieticians were the most influential for reducing the salty food intake of subjects. Saline sensitive group had relatively better control over salty food intake at every meal, eating out, and even when eating salty food that the spouse preferred. The saline sensitive group ate more frequently vegetables and fruits, whereas the saline insensitive group ate more frequently hot spicy foods. In conclusion, the results suggest that it is necessary to establish a social atmosphere toward reducing salt intake at the level of the government and food industry and to set action plans to be available for nutrition education programs to reduce salt intake nationwide.

Drought occurs extensively over a long period and causes great socio-economic damage. Since drought risk consists of social, environmental, physical, and economic factors along with meteorological and hydrological factors, it is important to quantitatively identify their impacts on drought risk. This study investigated the relationship among drought hazard, vulnerability, response capacity, and risk in Chungcheongbuk-do using a structural equation model and evaluated their impacts on drought risk using Bayesian networks. We also performed sensitivity analysis to investigate how the factors change drought risk. Overall results showed that Chungju-si had the highest risk of drought. The risk was calculated as the largest even when the hazard and response capacity were changed. However, when the vulnerability was changed, Eumseong-gun had the greatest risk. The sensitivity analysis showed that Jeungpyeong-gun had the highest sensitivity, and Jecheon-si, Eumseong-gun, and Okcheon-gun had highest individual sensitivities with hazard, vulnerability, and response capacity, respectively. This study concluded that it is possible to identify impact factors on drought risk using regional characteristics, and to prepare appropriate drought countermeasures considering regional drought risk.

This study is to clarify the market cycle of travelling merchants and the spatial behavior of consumer's commodity purchasing. its reasons and purchasing region of each commodity in Chongsan of Chongsan Myun(village) periodic markets, that is one of the lowest central places in Okchon county. The data used are the results of interviews with 58 travelling merchants on June 22 and July 17, 1994, and questionaire survey taken to parents of students of Chongsan middle school of Chongsan Myun in Okchon county. Study area is typical agricultural regions taking the role of central places to provide rural service and is comparatively important periodic markets. Some of findings are summarized as follows: (1) Until 1980's. appearance of closed periodic markets is caused by the population decrease in rural region, income increase, and rising of living level according to the Five Years Planning of Economic Development, appearance of chain stores of agricultural co-coperative and of supermarkets,. changes in distribution mechanisim by increasing consignment volume of agricultural products through agricultural co-coperative, and the development of transportation in Okchon county. These, too, became the reasons for the decline of the Chongsan periodic markets in Okchon county. (2) Most of the travelling merchants visiting the Chongsan periodic markets are in their 50's of age, and they sell the miscellaneous commodities and agricultural products. And about one-fourths of travelling merchants reside in regions with periodic markets and in Okchon of higher order central places. (3) Travelling routes visting periodic markets can be simplified to five types. Major types of travelling routes are Chongsan periodic market$\rightarrow$Wonnam$\rightarrow$Boun, and Chongsan periodic market$\rightarrow$Yungdong$\rightarrow$Yongsan. The patterns of travelling merchants visiting periodic markets are classified into the type of everyday visiting of periodic markets over three days of five days from merchant's residence to market, and the type of merchants or consumers visiting one day's of five days. On days that travelling merchants don't visit periodic markets they purchase the commodities in Seoul, Taejon and Chongju. (4) Consumers who use periodic markets are from thirties to fifties years of age and most of them are employed in agriculture. Consumers visit periodic markets on foot or by bus, and visit two or three times in a month, and mainly purchase the commodities for one or two hours from about ten o'clock in the morning. (5) Consumers purchase the necessaries of life in periodic markets, and other commodities are purchased in Taejon city, Youngdong, and Boun Eup(town). But consumers purchase the goods(convenience goods, shopping goods, and specialied goods) largerly in Chongsan, because additional expense and disadvantage after service with poor transportation service for purchased goods in others regions. Therefore, the hierarchies of central places by the consumer's purchasing behaviour can not be seem in dewellers in Chongsan and Chongseong Myun.

This study was conducted to investigate the occurrence of an acetolactate synthase (ALS) inhibiting herbicide resistant weed on paddy at 289 sites by soil sampling in Chungcheongbuk-Do of Republic of Korea from February to April in 2017. The most dominant weed was Monochoria vaginalis and Echinochloa oryzicola on each city and county. ALS inhibiting herbicide resistant ratio and occurrence area were 80.6% and 28,272 ha, respectively, in Chungcheongbuk-Do which was 3 times than in 5 years ago. The herbicide resistant ratio, Okcheon-Gun was the highest at 93.8%, Chungju-Si, Boeun-Gun, Yeongdong-Gun, Jincheon-Gun and Geosan-Gun were over 80%, Cheongju-Si, Eumseong-Gun and Jeungpyeong-Gun were over 70%. The herbicide resistant area, Cheongju-Si had the largest at 6,957 ha, Chungju-Si was 4,277 ha, Jincheon-Gun and Boeun-Gun was 3,536 ha and 3,282 ha, respectively. By weed, ALS inhibiting herbicide resistant ratio and occurrence area, Monochoria vaginalis was 49%, 17,646 ha, Echinochloa oryzicola 44%, 15,617 ha, Schoenoplectiella juncoides 29%, 10,377 ha, respectively. In all cities and counties of Chungcheongbuk-Do, Monochoria vaginalis and Echinochloa oryzicola are more than 40% resistant to ALS inhibiting herbicides, intensive management is required. The use of sulfonylurea herbicides is increasing, most farmers use herbicides 10 days after transplanting, so management after transplanting is necessary and the occurrence of herbicide resistant weeds should be reduced by alternating herbicide application every year.

우리나라 지역발전정책은 80년대 들어서 심화된 국토불균형 문제를 해소하기 위하여 지역경제 활성화 및 지방투자 촉진 목적의 다양한 정책 수단을 마련하면서 본격화 되었다. 수도권 소재 기업의 지방 이전을 위한 각종 법률과 제도가 제정 시행된 결과 일정 부분 성공했다는 평가가 있다. 충북지역 역시 수도권 소재 기업의 유치를 위하여 다양한 노력을 기울이고 있다. 이러한 중앙정부와 지방정부의 다양한 노력 결과, 2000년 이후에 충북으로 이전한 총수는 약 170여개 기업 정도가 되었다. 이들 기업은 업종별이나 지역별 등과 같은 그 구성 비율로 볼 때 고르지 못한 면이 있다. 예를 들어 기업의 지역별 이전기업 수를 보면 충주 46개, 청원 28개 기업으로 주로 충북 북부지역과 중부권에 집중되어 있고 영동과 보은 등의 남부권으로 이전한 기업은 거의 없어, 균형 개발 차원에서 남부 3군(옥천 포함)에 대한 충북도 차원의 지원이 필요할 것으로 보인다.
