Purpose: Under a trend of hospitals that repeated expansion in line with fast increasing factors of medical demands in the past, medical buildings where clinic businesses have regularly gathered in one building have exponentially increased since separation of prescribing and dispensing in 2000. Thus, this study aims at analyzing characteristics of architectural plan of the current medical buildings, identifying strengths and weaknesses through Post Occupancy Evaluation and suggesting an architectural planning method of medical buildings to be planned in the future. Methods: Scope of study has been limited to 23 medical buildings that are registered in the building register as medical buildings out of the Class 1 neighborhood facilities build as 5 floors or more in Cheongju region since 2000 and being actually used for the usage. Study method is to define concepts of the medical buildings through literature review and advanced researches, analyze characteristics of architectural plan through drawing analysis and site survey. Results: General characteristics of architectural plans for the medical buildings in Cheongju have been analyzed. There are the most frequencies in general commercial area and semi-residential area, most of them are reinforced concrete structure and the Class 1 neighborhood facilities. Average land area is $482.68m^2$, gross floor area $3720.8m^2$, the number of underground floors level 1.16, the number of floors level 7.76, total number of floors 8.92, the building-to-land ratio 67.28%, floor area ratio 452.6%, height 31.44m, and the number of parked vehicles 24.16. Implications: This research will contribute to the establishment of the planning methods which increase the quality of Medical Buildings in Cheongju.

Rural area development projects are being carried out in a strategy to create new value in agriculture and farm villages and to change the public perception. This study targeted rural experience participants visiting Cheong-Ho region, where the Rural Village Comprehensive Development Project was carried out. They were surveyed about attributes of visits to farm villages to determine which attributes of the experience could influence their revisits. This study was conducted under an umbrella project conducted as per the Special Act on Life Improvement and Regional Improvement for Farmers and Fishermen. Cheong-Ho region in Buan-gun produces mulberry, organic wheat, and rice grown using environmentally-friendly agricultural practices. This region as held events offering visitors the chance to experience rural villages and mulberry farms. Survey results showed that the natural landscape of villages, village experience, and the services provided by residents had a positive relationship with the probability of revisiting the village. Also, village facilities, harmony of natural landscape, hospitality of village residents, amusement value of rural experience, and the cost for rural experience were significant attributes. Therefore, it is necessary to revitalize the rural experience program targeting rural experience participants in Cheong-Ho region through continuous and monitoring of key visit attributes and revisit factors.

최근 교통 분야에서 발생하는 교통 빅데이터 (교통카드 데이터, ATMS 데이터 등)의 분석결과를 교통 정책에 활용하는 사례가 늘어나고 있는 추세이다. 또한 교통 데이터 분석 기법을 기존의 단순 빈도 분석 기법에서 다양한 데이터 마이닝 기법으로 확장하여 교통 데이터 속에 숨어있는 의미를 파악하려는 연구도 진행되고 있다. 본 연구에서는 교통카드 데이터에 대하여 토픽모델링 기법 중의 하나인 LDA (Latent Dirichlet Allocation) 기법을 적용하여 청주시 버스 승객들의 이동패턴을 분석한다. 이를 위해 교통카드 데이터의 하차 결측치를 추정하고, LDA 기법을 적용하여 이동패턴을 추출하였다. 또한 LDA 분석으로 도출된 값을 측정값으로 하여 다차원적 분석을 함으로써 청주시 버스 승객들의 이동패턴 특징을 파악할 수 있다. 분석 결과, 청주시의 경우 크게 1) 시외지역에서 터미널을 이용해 청주시에서 유입되는 패턴, 2) 주거지역에서 상업지역으로 이동하는 패턴, 3) 청주 인근 학교에서 상업 지역 (청주 중심가)로 이동하는 패턴을 발견할 수 있었다. 이동패턴은 도시 계획, 대중교통서비스 향상, 버스 노선 신설 등 다양한 교통정책의 수립에 활용될 수 있을 것으로 기대된다.

The author attempted to find most suitable formulas for probable rainfall intensities with analysis and consideration for characteristics of rainfall intensities according to the short and long period return periods at Cheong-Joo district. Above mentioned formulas induced by this study can be contributed to the credibility of runoff estimation for urban sewerage system, drainage works in small catchment area and embankment works in the rivers. The results of this study are summarized as follows: 1 Calculation values by Gumbel-Chow method were selected as a mean values for the calculation of probable rainfall intensities according to return periods in the short period. 2. Calculations for probable rainfall intensities for long period are based upon to the result by Iwai's method. Talbot type, {{{{I= {a} over {t+b} }}}} is confirmed as a most suitable formula for probable rainfall intensities among calculation methods in the short periods at Cheong-Joo district. 4. Specific coefficient method, I24=RN24${\beta}$N was selected as a means of calculation for suitable formulas of probable rainfall intensities according to return periods in case of long period. 5. Runoff estimation with high credibility by rational formula can be anticipated by establishment for the most suitable probable rainfall intensities at Cheong-Joo district.

Background : The genus Cypripediums are typically adapted to the low temperature and cold climates of the high land in Korea. The species which were reported in Korean peninsula are C.japonicum, C.macranthos, C.calceolus and C.guttatum. We had already reported the successful germination of the C.macranthos and C.guttatum. The small spotted lady's slipper orchid(C.guttatum) is most endangered plants to extinction of which population was reported less than 100 in Korea. The objective of the present research is restoration of the C.guttatum in ex situ and adaptation in high land and nursery. Methods and Results : The 350 seedlings of C.guttatum were transplanted in soil at alpine area(altitude 750m) and the nursery of Korea National Arboretum(KNA) in YangPyeong city on May 2019 and 2020 in order to verify the possibility of ex situ restoration. The sprouted ratio of the seedlings were less than 10% in the alpine area and 83% in the nursery of KNA. The reasons of the diverse survival ratio are presumed as the low moisture content in the soil and heavy shade of the alpine area. The 15 cypripedium species and 29 hybrids were also effectively adapted in the KNA rare plant garden. Conclusion : These results demonstrated the difficulties of the restoration for small spotted lady's slipper orchid in the natural habitation. From the above results, we may conclude that the critical factors of the genus Cypripedium are intensive care for the fragile seedlings during the 1^st year acclimatization.

The policy of the Ministry of education through the social awareness and issues are being changed. Accordingly, in response to the school building which also has to be changed. This study is Low-floor(1~2 floor) for high accessibility, important management and a lot of locomotion. This study is analysis by floor of newly established schools in Chungbuk. Facility and space on the possible low-floor situated are classified administrative zone, health zone, student support + local exchange zone, STEAM(creativity, personality) supporting zone. The administrative area includes administration office, principal's office and board rooms. The administrative zone is located against schoolyard. Because it is possible visual control of schoolyard. also it controls visitor access so it is placed near main entrance. Health zone is located near a special class, counseling center and wee class for emergency situation. and is located near schoolyard for visual control. Student support + local exchange area includes library and computer lab, audio-visual room, auditorium or gymnasium. It put more emphasis resident welfare, culture and education. So it opens for local residents. It is located center of few stories or near entrance. STEAM(creativity, personality) supports science lab, art room, family room. It is possible such a theory class, experience class and indoor and outdoor class. It is located few floors. This study is used as a reference for school building projects planing.

토양미생물에 의한 제초제 bentazon(3-isopropyl-2,1,3-benzothiadiazin-4-one-2,2-dioxide)의 분해를 구명하기 위하여 성질이 서로 다른 충북지역의 밭토양 2종과 논토양 2종을 담수 및 밭토양 조건하에서 $23{\pm}1^{\circ}C$ 배양하였다. Bentazon 200 ppm을 처리한 Cheong Won A 토양 (Silty loam; pH, 5.2; 유기물 함량 1.4%)을 6개월 동안 담수상태에서 배양하였을 때 주 분해산물로 6-hydroxy bentazon (1.27%) 및 소량의 8-hydroxy bentazon (0.57%,)과 anthranilic acid (0.13%)가 형성되었다. 한편 bentazon 500 ppm을 처리한 동일토양을 2개월 동안 배양하였을 때는 소량의 6-hydroxy bentazon이 형성되었다. 8종의 미생물을 토양으로 부터 분리하여 순수배양실험을 하였으나 뚜렷한 분해산물을 검출하지 못하였다. Cheong Won A 토양이 Cheong Ju A 토양보다 더욱 큰 dehydrogenase 활성을 나타낸 것으로 보아 전자가 후자보다 더 큰 bentazon 분해력을 가질 것이라고 추측되었다. 세균 14종과 곰팡이 8종에 대하여 bentazun 10 ppm을 처리하고 14일간 배양하였을 때 Rhizopus stolonifer만이 주 분해산물로 anthranilic acid (4.6${\sim}$31.6%) 그리고 소량의 6-hydroxy bentazon과 8-hydroxy bentazon (1.27%)을 형성하였으며, 나머지 미생물에서는 대사산물을 검출할 수 없었다.
