Self-sufficiency rate of food in South Korea is almost at the lowest level among OECD countries, and the decrease tend of farmland is expected to be continued. In this situation, the government has been revised the target self-sufficiency rate of food, and carried forward various policies in order to achieve it. One of those policies is the restoration business of idle farmland which is planned to carry forward after 2015. This study set up indicators evaluating effective use of idle farmland, and tried to apply in the field before carrying forward restoration business. The result of this study may be summarized as follows. First of all, it reset an evaluation indicator that was based on the evaluation indicator developed in order to set application directions of idle farmland. Next, it selected 30 idle farmlands with reset evaluation indicator among 11,635 which were inspected nationwide in 2012. Before applying indicator, it measured the condition of recycling such as accessibility of farmland, condition of irrigation and drainage system, land state, and surroundings by field investigation. Then, it calculated composite score in each target area through applying indicators, and verified the indicator by comparing calculated result with the one which was decided from field investigation. Finally, it carried out field investigation, correct and upgrade some problems of the standard of score calculation that was found during applying previously set evaluation indicator to target area, and established the final standard of calculation for evaluation indicator.

The purpose of this paper is to seek out the problems influencing on the operation of Institution Evaluation(IE) in Korea and suggest a better way for the evaluation based on the findings, expecially focusing on Government Research Institute(GRIs) in the field of Science and Technology. Unlike previous studies on IE of GRIs, this research is more oriented toward actual practices than design and theories of IE. Three categories are 1) purely system aspect, 2) system-operation aspect, and 3) environmental aspect. These three categories are classified into eight sub-categories: 1) the legal support and the legally enforceable provision, 2) the target area of evaluation, 3) the means and process of evaluation, 4) the criteria and indices for evaluation, 5) the expertise of evaluators, 6) the use of evaluation findings, 7) GRIs' support for IE, and 8) public support for IE. Summing up the findings of this study, the main factors that hamper the successful operation of the existing IE of GRIs in the field of Science and Technology was illuminated and the better way for the operation of IE was suggested.

We assessed the persistence of eight major cruciferous crops-leaf mustard, oilseed rape, cabbage, broccoli, cauliflower, Chinese cabbage, turnip, and radish-growing in the field. In the first part of our experiment, we tested the viability of seeds that had been buried at two different soil depths for up to 16 months. We then broadcast seeds over the soil surface and left them undisturbed to investigate the survivorship of the resultant plants over two years. Seed viability was significantly affected by plant taxa and burial depth, but not substantially affected by the duration of burial. Although seeds of leaf mustard had the greatest viability among all crops examined here, the viability rates were significantly lower at 2 cm depth than at 15 cm. Seeds of leaf mustard, oilseed rape, broccoli, turnip, and Chinese cabbage remained viable throughout the 16-month period. A study of plant demography revealed that only leaf mustard and oilseed rape succeeded in producing seeds and overwintering in the undisturbed field. However, neither of those species competed well with other plants long-term and their overall growth and survival rates declined during the evaluation period. In addition, insect herbivory severely decreased the growth of all of these crops. Our results suggest that populations of leaf mustard and oilseed rape do not tend to persist in the field for more than a few years without disturbance and external seed inputs.

Recently, low-cost particulate matter (PM) sensors have been widely used in monitoring mass concentration. Maintaining the accuracy of the sensors is important and requires rigorous performance evaluation and calibration. In this study, two commercial low-cost PM sensors(LCS), Plantower PMS3003 and Plantower PMS7003, were evaluated in the laboratory and field with a reference-grade PM monitor (GRIMM 11-D). Laboratory evaluation was conducted with single/mixed particles of PSL (Poly Styrene Latex) in an acrylic chamber at 20℃ and relative humidity of 20%. Field evaluation was conducted inside a building of Yonsei University (Shinchon) from February 12 to March 31, 2022. In both evaluations, LCS measured values became different from reference measured values when the relative humidity was high or the outdoor air PM10/PM2.5 ratio was high. Based on the field evaluation, the LCS measured values were corrected through four different regression analysis models. As a result, the multivariate polynomial regression analysis model showed highest matching with the reference PM monitor (PM2.5 >0.9, PM10 >0.85). In this model, the PM10/PM2.5 ratio and relative humidity were chosen as independent variables.

PURPOSES : Surface treatment material for pavement preventive maintenance should be inspected field applicability. This study(Part II) aimed to checkup coating characteristics and performance analysis using lab and field tests. The hydrophobic - low viscosity filling material for pavement preventive maintenance is presented in Part I, which is a series of companion study. METHODS : Relative comparison between general asphalt mixtures and surface treatment asphalt mixtures are analyzed and measured for the field application such as indirect tensile strength ratio(TSR), abrasion resistance, crack propagation resistance, temperature resistance, coating thickness, permeability resistance and skid resistance in terms of british pendulum number(BPN). RESULTS : It is found that TSR, crack propagation resistance and permeability resistance is increased as against uncoated asphalt specimen. Abrasion resistance and temperature resistance is secured from the initial coating thickness point of view, which is about 0.2~0.3mm. Skid resistance on the surface treatment pavement is satisfied with the BPN criteria of national highway because of exposed aggregate and crack sill induced pavement deterioration and damage cracks. CONCLUSIONS : The hydrophobic - low viscosity surface treatment material for pavement preventive maintenance is validated on field applicability evaluation based on quantitative analysis of coating thickness and performance analysis using lab and field tests.

1. Library practice education in Korea is in the form of field experience, that is, Practicum, which is one type of field experience. 2. The practicum is a short-term work experience guided by the academic institutions. (2 to 6 weeks of full time employment in a library, or one to two semesters of approximately 10 to 12 hours weekly) 3. Field work is largely accepted as a required subject. 4. Field work is usually carried out during the first semester of senior year. (or of sophomore year in junior college) 5. Libraries in other universities (or in other institutions) can beused for a student's field work. But the current tendency is to use his or her own university's library. 6. Most universities give one credit for 2 weeks' field work. 7. The method of evaluation is strict: A or 'excellent' (above 90), B or 'good' (above 80), C or 'fair' (above 70), D or 'bad' (above 60). 8. The expense of field work is usually included in the tuition fees. However, some think that an additional fees should be collected in the case of special practice. 9. Respondents to my survey say that the field experience is necessary so that professional librarians can connect theory and practice. 10. They also indicate that there are some problems in library practice education: administrative difficulties in the department chairman's office, the burden on professors in the library being used, and the limited number of libraries in which the field work is practicable. 11. The Department of Library Science is responsible primarily for providing faculty supervision over the students, and secondarily for the preparation of evaluation cards and field work reports. 12. Most of the faculty respondents use evaluation cards for the field work, some of which serve as grade sheets, some as field work diaries, and some as field work reports.

대학도서관 평가는 대학도서관의 수준 향상을 위한 기본전략이라고 할 수 있다. 이에 대통령 직속 도서관정보정책위원회에서는 2005년도에 한국교육학술정보원에서 개발된 대학평가지표를 이용하여 시범평가를 함으로써 대학도서관들의 의견을 수렴하여 평가지표의 타당성과 실효성을 검증하고 향후 적용 방안에 대한 시사점을 얻고자 하였다. 그 결과 평가항목 및 지표부분에 있어서 시정사항이 요구되었으며, 본 연구는 시범평가에서 나타난 문제점을 해결하고 대학도서관에 적용할 수 있는 평가지표를 제시하고자 하였다. 평가지표 세부수정내용은 첫째 평가분야를 7개 분야에서 재화자원과 시설자원을 '예산 및 시설자원'으로 통합하여 6개 분야로 줄였다. 둘째, '도서관경영' 분야의 '이용자헌장과 '기획' 항목을 제거하고 '도서관 자체평가' 항목을 추가하였으며, '정보자원' 분야에서 '비도서 및 기타자료' 평가항목을 추가하였다. 셋째, 재화자원 및 시설자원을 통합하여 '예산 및 시설'로 하였으며 평가지표는 예산항목과 도서관시설로 수정하였다. 넷째, '정보이용' 분야에서 '장서회전율'을 '장서이용'에 통합시키고. '정보서비스'분야의 '도서관 이용율' 항목을 '정보자원' 분야로 이동시킨 후 '이용율'로 항목이름을 바꾸었다.
