제주특별자치도개발공사에서는 제주의 청정자원 가치를 창출하여 도민을 위한 사업이 다양하게 펼쳐지고 있다. 그중 우리나라 시장점유율과 선호도, 만족도에서 최고 1위 자리를 차지하며 2009년 가치 브랜드로 선정된 먹는 샘물 "제주삼다수"가 대표적이다. 그러나 제주도 총 생산의 18%를 차지하는 감귤에 있어서도 감귤농가 소득향상에 기여하는 사업이 있다. 상품가치가 없는 감귤 때문에 손실을 볼 수 있는 감귤농가에 감귤을 전량 사들여 새로운 제주도 특산품으로 가공하는 사업, 바로 음료사업이다. 그 선두에 제주도민의 행복한 삶을 제공하고 있는 감귤제1가공공장이 있다. 감귤제1가공공장에는 농축액공정과 주스공정이 있다. 1일 400톤의 가공된 농축액과 주스가 생산되는 제1공장은 5개의 공장동과 관리동에서 감귤, 녹차 가공공정이 분주하게 돌아가고 있다. 여기서 가장 중요한 것은 안전, 안전을 최우선으로 확보되어야 제주 도민을 위한 일도 할 수 있는 것이고, 수익 또한 창출 된다는 것이 이곳 사람들의 생각이다. 안전을 위해서는 나부터 시작하여 나와 동료의 안전을 지킨다는 감귤제1가공공장을 둘러본다.

Bovine viral diarrhea virus (BVDV) is distributed in cattle worldwide and causes significant economic losses to the livestock industry. Identification and remove of BVDV persistently infected (PI) cattle is very important to control BVDV infection in cattle herd. The objective of this study is to investigate the infection status of BVDV infection in Korean native cattle (Bos taurus coreanae) farms located in Jeonbuk State. From 2021 to 2022, a total of 1,497 samples were collected from 17 cattle farms and tested for BVDV antigen using a commercial ELISA kit. By the first ELISA testing, 24 cattle from six farms were positive for BVDV antigen, showing the farm-level or cattle-level prevalence of 35.3% or 1.6%, respectively. By the second ELISA testing which carried out with the first ELISA-positive samples after three-weeks, 12 cattle (0.8%) from five farms (29.4%) were positive for BVDV antigen, indicating these cattle were PI cattle. Genotypes of BVDV were determined with 12 BVDV-positive samples using a previously described RT-PCR assay and the results showed that 3 (25.0%) and 9 (75.0%) were confirmed to be type 1 and type 2, respectively. These results will be helpful to establish the effective control strategy for BVDV in cattle farms in Jeonbuk State.

A broiler farm in Jeonbuk province experienced high mortality due to decreased feed intake and poor growth, and pathological evaluation of 11- and 17-day-old broilers was performed, which led to the diagnosis of runting-stunting syndrome. From the start of the rearing period to shipment, 18.4% of the chickens in the three barns experiencing continuous culling and mortality were affected, compared to 7.7% in the other five barns. Gross findings on the 11-day-old broiler chicken revealed proventricular dilatation and hemorrhage, intestinal hemorrhage, urate deposition in the pericardium and renal tubule, nephropathy, and mild hepatic capsulitis. Similar proventricular dilatation and hemorrhage were observed in the 17-day-old broiler chickens. In addition, hepatitis and pericarditis were observed with the progression of secondary bacterial infection, and pathogenic Escherichia coli was isolated from these lesions. As a result of PCR, Newcastle disease virus, fowl adenovirus, chicken anemia virus and Marek's disease virus were not detected in the all tissue samples. In contrast, infectious bronchitis virus was detected in the proventriculus, kidney and cecal tonsil. chicken astrovirus was detected in the intestine, cecal tonsil and bursa of Fabricius, and chicken parvovirus was detected in proventriculus, intestine, cecal tonsil and bursa of Fabricius. By sharing the diagnostic process of a case of malabsorption syndrome through this case report, we hope that it can be widely utilized in the diagnostic process of livestock disease pathognomonic institutions.

The purpose of the study is to identify and understand problems existing in the middle school home economics practice rooms in Jeju Special Self-Governing Province. The findings are based on the examination and the analysis of the indoor environment and the condition of the facilities and equipment. Study method employs on-site research and a survey. The on-site research was conducted about temperature, humidity, intensity of illumination, and status of teaching instrument in 10 out of 41 middle schools in Jeju Special Self-Governing Province from August 16 to September 30, 2006. Meanwhile, the survey was implemented by mail for 95 teachers in charge of manual training and home economics education in 41 middle schools in Jeju from November 1 to 23, 2005. 64 questionnaires out of total 95 were collected, including those collected during the period of on-site research. Finally, 61 questionnaires which were effective among the answered ones were used for analysis. Collected materials were analyzed with the SPSS Win.12.0 program for frequency, percentile analysis. In conclusion, the study determines that the condition of the home economics practice rooms of the middle school in JSSGP in terms of temperature, humidity, lighting and ventilation is very inadequate. The structure of the practice room represents an inefficient work flow pattern. Further, the facilities and equipment are in a very poor condition because the facilities are old and the retention rate of teaching tools is low. Therefore, to address these problems, the study suggests that improvements on the facilities and equipment should be made and teaching tools should be replenished in accordance with the industry standard.

This study analyzed the density and mortality rate of Korean fir at 9 sites where individuals of Korean firs were marked into the live and dead trees with coordinates on orthorectified aerial images by digital photogrammetric system. As a result of the analysis, Korean fir in each site showed considerable heterogeneity in density and mortality rate depending on the location within site. This make it possible to assume that death of Korean fir can occur by specific factors that vary depending on the location. Based on the analyzed densities and mortality rates of Korea fir, we investigated the correlation between topographic factors such as altitude, terrain slope, drainage network, solar radiation, aspect and the death of Korean fir. The density of Korean fir increases with altitude, and the mortality rate also increases. A negative correlation is found between the terrain slope and the mortality rate, and the mortality rate is higher in the gentle slope where the drainage network is less developed. In addition, it is recognized that depending on the aspect, the mortality rate varies greatly, and the mean solar radiation is higher in live Korean fir-dominant area than in dead Korean fir-dominant area. Overall, the mortality rate of Korean fir in Mt. Halla area is relatively higher in areas with relatively low terrain slope and low solar radiation. Considering the results of previous studies that the terrain slope has a strong negative correlation with soil moisture and the relationship between solar radiation and evaporation, these results lead us to infer that excess soil moisture is the cause of Korean fir mortality. These inferences are supported by a series of climate change phenomena such as precipitation increase, evaporation decrease, and reduced sunshine duration in the Korean peninsula including Jeju Island, increase in mortality rate along with increased precipitation according to the elevation of Mt. Halla and the vegetation change in the mountain. It is expected that the spatial patterns in the density and mortality rate of Korean fir, which are controlled by topography such as altitude, slope, aspect, solar radiation, drainage network, can be used as spatial variables in future numerical modeling studies on the death or decline of Korean fir. In addition, the method of forest distribution survey using the orthorectified aerial images can be widely used as a numerical monitoring technique in long - term vegetation change research.
