본 연구는 급경사지 정비 사업 이후 현장을 재평가하고, 등급을 산정할 때 보강시설로 인한 등급 하락의 효과성을 검증하기 위해 역량 지표를 추가하여 12명의 전문가와 15개 지점에 대한 현장평가를 실시하였다. 15개 지점 중 11개소에서 점수가 변화되었으며, 6개의 지점에서 등급이 하락하였다. 등급의 변화가 크지 않아 개선해야 할 점이 있지만 본 연구는 향후 급경사지 등급 조정 연구에 활용될 수 있을 것으로 판단된다

데이터 증강은 데이터 불균형 문제를 해결하기 위해 일반화 성능을 향상시킨다. 이는 과적합 문제를 해결하고 정확도를 높이는 데 도움을 준다. 과적합을 해결하기 위해서 본 논문에서는 분할 마스크 라벨링을 자동화하여 효율성을 높이고, RoI를 활용한 분할 Copy-Paste 데이터 증강 기법을 제안한다. 본 논문의 제안 방법을 적용한 결과 YOLOv8 모델에서 기존의 분할, 박스 Copy-Paste 데이터 증강 기법과 비교해서 쓰러진 사람 객체에 대한 정확도가 10.2% 증가함으로써 제안한 방법이 일반화 성능을 높이는 데 효과가 있음을 확인하였다.

국방부와 각 군은 1970년대 말부터 장교자력표 전산화를 시작하여 군별, 인사기능별로 정보화를 추진하였고 1990년대 중반에 현재의 수준으로 업그레이드하여 운영하고 있다. 그러나 인사정보화는 종합적인 Master-plan도 없이 각 군 본부 실무자의 단위업무를 지원하기 위한 응용프로그램 위주로 개발됨에 따라 국방차원에서는 중복개발, 예산낭비, 기관별/기능별 상호 운용성 결여 등의 많은 문제점이 노출되었다. 본 논문의 연구방법은 군 인사체계의 현실태를 분석하여 문제점 및 개선방향을 도출하고 이를 기초로 새로 구축할 국방인사정보체계의 모델과 정보화 전략을 제시하고자 한다.

온라인 쇼핑의 증가로 인해 상품평(리뷰)의 중요성이 높아지고 있다. 본 연구에서는 리뷰 데이터를 수집하고 이를 분석하여 상품의 판매 전략 개선 모델을 개발하였다. 이를 위해 웹 크롤링과 OCR 기술을 활용하여 댓글을 텍스트로 변환하고, Chat GPT 4o model를 사용해 댓글을 분석하였다. 모델을 통해 얻은 결과 데이터는 상품의 품질, 가격, 배송 등의 측면에서 주요한 피드백 요소들을 도출하는데 사용되었다. 본 연구는 IT 기술과 심리학적 요소를 결합하여 소비자 행동을 분석하는 새로운 접근 방식을 제시하며, 이를 통해 보다 효과적인 마케팅 전략을 수립할 수 있음을 보여준다.

Recently, with the rapid expansion of the franchise restaurants, ensuring food safety has become essential for restaurant growth. Consequently, the need for food safety training and related material is in increasing demand. In this study, we identified potentially hazardous risk factors for ensuring food safety in restaurants through a food safety monitoring tool, and developed training materials for restaurant employees based on the results. The surveyed restaurants, consisting of 6 Korean restaurants and 1 Japanese restaurant were located in Seoul. Their average check was 15,500 won, ranging from 9,000 to 23,000 won. The range of their total space was 297.5 to $1322.4m^2$, and the amount of kitchen space per total area ranged from 4.4 to 30 percent. The mean score for food safety management performance was 57 out of 100 points, with a range of 51 to 73 points. For risk factor analysis, the most frequently cited sanitary violations involved the handwashing methods/handwashing facilities supplies (7.5%), receiving activities (7.5%), checking and recording of frozen/refrigerated foods temperature (0%), holding foods off the floor (0%), washing of fruits and vegetables (42%), planning and supervising facility cleaning and maintaining programs of facilities (50%), pest control (13%), and toilet equipped/cleaned (13%). Base on these results, the main points that were addressed in the hygiene training of restaurant employees included 4 principles and 8 concepts. The four principles consisted of personal hygiene, prevention of food contamination, time/temperature control, and refrigerator storage. The eight concepts included: (1) personal hygiene and cleanliness with proper handwashing, (2) approved food source and receiving management (3) refrigerator and freezer control, (4) storage management, (5) labeling, (6) prevention of food contamination, (7) cooking and reheating control, and (8) cleaning, sanitation, and plumbing control. Finally, a hygiene training manual and poster leaflets were developed as a food safety training materials for restaurants employees.

Mean values representing the particle size distribution and some chemical properties for the cultivated soils were obtained from the analysis results of the typical profiles, which were described by the detailed soil maps throughout Korea. Analysis results of 5,215 soil samples (3,075 for paddy and 2,140 for upland) were available for the determination of mean values. The results are under. 1. Paddy topsoil contained 20.4% for clay, 5.8 for pH, 2.6% for organic matter, 10.4me/100g for exchangeable K, and 89ppm for available $P_2O_5$. Upland topsoil did 17.3% for clay, 5.5 for pH, 1.8% for organic matter, 9.lme/100g for CEC, 0.29me/100g for exchangeable K, and 103ppm for availabal $P_2O_5$. 2. Soil properies for paddy were markedly influenced by the reliefs. Topsoil contained 21.4% for clay, 6.0 for pH, 2.2% for organic matter, 10.8me/100g for CEC, 0.39me/100g for exchang-cable K and 57ppm for available $P_2O_5$ on the fluvio-marine plain, 15.3%, 5.7, 2.0%, 8.6me/100g, 0.17me/100g and 76ppm on the alluvial plain, 18.8%, 5.9, 2.7%, 10.4me/100g, 0.19me/100g and 80ppm on the valleys and fans, 25.0%, 5.7, 2.5%, 11.5me/100g, 0.26me/100g, 0.27me/100g and 141ppm on the moutain foot slopes, respectively. 3. Soil Properties for upland, also, were markedly influenced by the reliefs. Topsoil contained 5.5% for clay, 5.7 for pH, 1.1% for organic matter, 4.7me/100g for CEC, 0.17me/100g for exchangeable K and 50ppm for available $P_2O_5$ on the fluvio-marine plain, 10.3%, 5.5, 1.4%, 7.6me/100g, 0.26me/100g and 160ppm on the alluvial plain, 13.9%, 5.4, 1.8%, 9.3me/100g, 0.24me/100g and and 184ppm on the valleys and fans, 29.8%, 5.3, 2.1%, 11.2me/100g 0.40me/100g and 58ppm on the alluvial plain, 20.0%, 5.7, 2.7%, 11.4me/100g, 0.32me/100g and 116ppm on the mountain foot slopes, and 24.6%, 5.3, 1.8%, 10.2me/100g, 0.28me/100g and 51ppm on the rolling and Hill. 4. All chemical properties did not reach the ideal value for maximizing land capability. 5. Organic matter, exchangeable cations and available $P_2O_5$ were not normally distributed. Intervals of one and two standard deviations about mean of an approximately normal distribution were calculated.

A computer program was developed to select the optimum size of farm machine and analyze its operation costs according to various farming conditions. It was written in FORTRAN 77 and BASIC languages and can be run on any personal computer having Korean Standard Complete Type and Korean Language Code. The program was developed as a user-friendly type so that users can carry out easily the costs analysis for the whole farm work or respective operation in rice production, and for plowing, rotarying and pest controlling in upland. The program can analyze simultaneously three different machines in plowing & rotarying and two machines in transplanting, pest controlling and harvesting operations. The input data are the sizes of arable lands, possible working days and number of laborers during the opimum working period, and custom rates varying depending on regions and individual farming conditions. We can find out the results such as the selected optimum combination farm machines, the overs and shorts of working days relative to the planned working period, capacities of the machines, break-even points by custom rate, fixed costs for a month, and utilization costs in a hectare.
