This study was conducted to investigate and analyze gerbera cultivation and the status of smart farms in Korea. The survey was conducted in person for 81 farms, in 2020. About 71.6% managers of the gerbera farms were in their 50s and 60s, 16% in their 30s and 40s, 9.9% were over 70, and 2.5% under 30. About 37% of the farmers have cultivation experience of less than five years; 25.9%, 6–10 years; 29.6%, 11–20 years; and 7.4%, over 21 years. Around 61.7% of the area under gerbera cultivation was 0.3–0.6 ha, 30.9% was less than 0.3 ha, and 7.4% was over 0.6 ha; and the average area under cultivation was 0.37 ha. The average family labor of the gerbera farms was 2.1 people and the employed labor was 0.8 people. The cultivation methods included about 88.9% soil and 11.1% nutrient cultivation farms. However, 61.7% of the farmers cultivated all or part of the domestic gerbera varieties, whereas 38.3% only cultivated foreign varieties. In the pest survey, around 91.4% of the farm managers responded to have observed different diseases, and around 98.8% farms exhibited various pests. The smart farm system has been installed by 12.3% of the farming households. However, 76.9% of farming households with no prior smart farms are planning to install them in the future. Future plans include the status quo of 80.2%, reduction in total area by 8.6% and expansion in total area by 11.1%, and around eight farms in Gyeongbuk and one farm in Gyeongnam area are planning to expand their management.

본 연구는 수피 부산물 비료의 돈분 부산물 비료의 부숙단계별 시료의 유기물 분획의 함량 변화, Δlog K값과 RF값 등의 분광학적 특성 변화, 원형여지 chromatograp의 변화를 측정하여, 부숙도의 판정 기준 설정을 위한 기초 자료로 활용하는데 그 목적이 있다. 그 결과를 요약하면 다음과 같다. 수피와 돈분 부산물빌 중 HA-C와 FA-C의 함량은 대체로 부숙이 진행됨에 따라 감소하는 경향이었고, HA-C/FA-C 비는 증가하였다. 수피와 돈분 부산물 비료의 Δlog K값은 부숙이 진행됨에 따라 감소하였으며, RF값은 증가하였다. 생수피의 부식산 형태는 R_p 형태였으나, B형태를 거쳐 120일경과 후 A형태로 변화하여 거의 완숙상태에 도달하였으며, 돈분 부산물 비료의 경우 40일경과 후에도 B형태로 나타나 유기물질의 부숙이 진행중인 것으로 판단되었다. 수피부산물 비료의 원형여지 chromatograph는 120일경과 후에 규칙적인 톱니 모양을 하고 있어 완숙단계에 이른 것으로 판단할 수 있었으나, 돈분 부산물의 경우는 40일이 경과한 후에도 부분적으로 불규칙적인 모양을 하고 있어 부숙이 진행되고 있는 상태인 것으로 판단할 수 있었다. Changes of the spectroscopic characteristics of the organic matter fractions and circular filter paper chromatograph were assessed for the bark and piggery manure composts during the composting. as an approach to base the criteria of the compost maturity evaluation. Contents of humic acid-C (HA-C) and fulvic acid-C (FA-C) in both bark and piggery manure composts were decreased as the composting got closer to maturity, but the ratios of HA-C/FA-C were increased. During the composting. Δlog K values were decreased, but RF values were increased. Humic acid of the mature bark compost after 120 days of composting was A-type, as compared to Rp-type for the raw bark and B-type for the immature compost. However. humic acid of the mature piggery manure composts after 40 days of composting was B-type, indicating the humification of the organic matter fractions continued at this stage. Circular filter paper chromatograph of the mature bark compost exhibited the regular sawteeth pattern at the edge, but that of the mature piggery manure showed an irregular sawteeth pattern. Results demonstrated that spectroscopic characteristics and circular filter paper chromatograph of the organic by-product composts might be employed for the compost stability assessment.

河在明,崔武革 慶北大學校 1991 論文集 Vol.51 No.-

This thesis aims at studying one of the ways which grasps exactly environmental qualities. For this purpose, this paper examines the cognitive dimensions of environmental identity which is the identity that a person or group has with his environment, in particular when he is experiencing it as an insider. There are two important dimensions: the vertical dimension and the horizontal dimension. The vertical dimension is classified by the degree of relationship between the observer and the environment. The horizontal dimension is classified by the scale of the environment concerned with its users.

This study was carried out to evaluate the relations among working environments, health behaviors and satisfaction with their duty in a group of 200 ship-repair workers in the ROK navy. The results were as following; Age of workers was 40 years and over(83%) and working duration was 10 years and over (71.5%). Most of them were married and had studied beyond high school. The 69.5% of workers satisfied with their job, whereas. about 59.5% of workers had satisfaction with their working condition. There were current drinkers, 78.5%, current exercising workers, 43.5%, obese workers, 28.0%, and salted food intakers, 18.5% in the workers. The major harmful environmental factors in the ship-repair workplace are noise, vibration, dust and chemicals. Most of workers are exposed to above harmful factors and complained about exposure of noise and dust. The consumption of cigarette or alcohol in people who exposed to noise was much higher than in people who did not, but the difference was not statistically significant. Prevalence of obesity and hypertension were not significantly different between the exposure with noise and dust. Noise or dust exposure was significant relation to satisfaction with their duty and working condition. The affective factors for satisfaction with their duty were people who worked for 10 years or more(OR= 4.53), exercisers(OR=4.78) and dust(OR=3.05) in Logistic regression analysis.

위성 통신 기술의 발달로 국부적으로 수행리던 위치 추적의 범위가 선 세계로 3~4간되었다 하지만 기존의 물류 관제 시스템들은 관제 서버와 물류간의 통신을 위하여 휴대폰 통신망을 이용하기 때문에 일부 지역 내에서 이동하는 물류에 대해서만 관제가 가능하다. 이 논문에서는 위성 통신을 이용하여 전 세계를 이동하는 물류 매체인 냉동 컨테이너의 위치 및 상태 정보를 관리하기 위한시스템을 제안하였다. 제안 시스템은 냉동 컨테이너의 상태를 직절 관제하는 데이터 수집부, 관제서버와의 통신을 담당하는 위성 통신부, 냉동 컨테이너 정보를 판리하는 관제부로 구성된다. 시스템의 관제부에서는 냉동 컨테이너의 위치 주적 및 관제를 효과적으로 수행하기 위하여 기존의 TB 트리를 기반으로 하는 다중 버전 이동 객체 색인을 사용하였다. 제안된 냉동 컨테이너 관제시스템은 화주, 운송회사 등 육해상 물류관련 기관에서 냉동컨테이너 및 선박 위치추적, 컨테이너 통제, 컨테이너 통계 등 다양한 용도로 사용될 수 있어 화주에게는 컨테이너 운송에 대한 서비스를 제공하며, 선사에게는 선박안전경보시스템, 선박 관리, 냉동컨테이너를 효율적인 관리 기능을 제공하게 한다. As developing satellite communication, the tracking range of the moving objects which move in local area is expanded to the whole world. However previous logistics management system is able to monitor freight which transporting in local area using mobile communication system. In this paper, we propose the reefer container management system that manages the location information and other related information such as temperature, humidity of container using the satellite system. The proposed system consists of three parts; data collector, satellite communication manager, reefer container information manager. And the proposed system uses the moving object index for managing the trajectory of container and tracing the location of container or vessel that is transporting the container, and supports various services such as reefer container and vessel tracking, container control and container statistics to logistic companies like shipper and forwarding agent. And the system can be increasing the quality of container transportation service to the shipper, and it makes the efficient management of reefer container to the shipping company.

Anisakiasis refers to parasitic infestation by nematode larvae that belongs to the subfamily Anisakinae, and this condition is seen in people who eat inadequately prepared or raw salt-water fish. While gastric anisakiasis is commonly diagnosed by endoscopic technique, intestinal anisakiasis is rare because it is less common and the clinical and radiologic features are poorly understood. The authors report a case of human anisakiasis involving the ileocecal valve in 62-year-old man who had the history of eating raw cuttlefish.

To investigate nutrient dynamics of the lake and fish community, both water and fish samples were collected at three different areas (dam site, upper inflowing and downstream of lake outfow) for one year from Sep.2004 to Aug.2005 During the experimental periods, mean concentration of chl, a in epilimnetic layer (0-5m) was 18.5mg^(-3) and transparency ranged from 0.3m to 2.4m, respectively. In nutrient, mean concentrations of TP and TN were 111 mgP m^(-3) and 4.4 mgN L^(-1), respectively. Based on the water quality standard suggested by U.S.EPA(*1976), the trophic state of Lake Doam was classified as eutrophic state. Total number of fish collected in Lake Doam was 9,600 indiveduals in 26 species of 6 family. Sixteen of Korean endemic soecies including H. mylodon, A. signifer, P. tenuicorpa occurred. O. mykiss as introduced fish was also found in Lake Doam. Dominant and subdominant species were P. herzi and Z. platypus that took about 34.6% and 22.5% of total fish composition, respectively. Six species including A. signifer. P. tenuicorpa. and R. kumgangensis were rare in Lake Doam. Pelagic typw of figh commonly occurred at upper regions, whereas benthic type was mainly domenated at downstream area. Therefore, pollution source inflowed from the upper regions did not seriously affect downstream area (Songcheon water system) due to the role of dam as pollutant barrier. In addition high appearance of Comat type of fish that si hybrid between gold fish (C.auratus) and C. auratus was found in the lake, It was unclear the reasons that high prorortion of mutant species apperared in the lake. Further more researches are required in this area.

Free flaps have been widely used in lower leg reconstruction. However, in cases with extensive injury to the vessels as well as to the bone and soft tissues, and having only one intact major vessel in the lower leg(single vessel leg), careful selection of recipient vessels for the free flap transfer is mandatory for preventing further vascular compromise of the distal lower leg. The sural artery and its vena comitantes are frequently protected form externally harmful forces by the bulky surrounding gastrocnemius muscle and can be used as recipient vessles for free flaps without any detrimental influence on the vascularity of the distal lower leg. In our department, three latissimus dorsi muscle free flap were transferred with sural vessels as recipient vessels in the reconstruction of the single vessel legs. Except for one case of flap failure due to serious infection at the microvascular anastomoses site, all the other cases were successfully reconstructed without any necrosis of the gastrocnemius muscle or the distal leg. In addition, the sural vessels were easily accessed in any patient position and their caliber was similar to that of the vascular pedicles of the donor muscle flaps. In conclusion, the sural vessels can be another useful option in selecting recipient vessels for free flap transfer in the reconstruction of the single vessel leg.
