As a result of analyzing the domestic and foreign HACCP systems, advanced countries mandated HACCP system on all foods to strengthen food safety management and USA, EU and China do not apply small-scale HACCP system. Looking at the cases of food safety accidents in Korea and the non-compliance rate of HACCP certification evaluation by size, the accident rate of companies without HACCP certification was 31.2% higher than that of companies with HACCP certification. The nonconformity rate of food inspection standards was analyzed to be 89.0% higher than that of HACCP certification companies. Based on the international trend of food safety management and the frequency of food safety accidents, it is proposed to gradually expand the mandatory application of HACCP system in Korea to all foods, and to change the small-scale HACCP standard from less than 500 million Korean won or 21 employees to less than 500 million Korean won.

N/A Background: In patients with intractable constipation who are poorly responsive to medical treatments, surgical treatments may be considered. However, how preoperative physiologic evaluations contribute to some information in making surgical decision is not established. The aim of this study was to evaluate the outcome of surgical treatment in patients with severe constipation who underwent preoperative functional study. Methods: Preoperative functional evaluation included colon transit time test, defecography, scintigraphic gastric emptying time test, anorectal manometry and balloon expulsion test. Nine patients with a mean age of 48 years old were taken total colectomy with ileorectal anastomosis. Slow colonic transit was demonstrated in each case. All patients were available for follow-up, with median time of 35 (range; 10-55) months. Results: Seven patients (78%) were satisfied with outcome, improved the quality of life, and felt the operation was valuable despite of residual symptoms. Two patients did not experience symptom improvements. Six of seven colonic inertia or combined spastic pelvic floor syndrome patients had a satisfactory outcome. In contrast, one of two patients with generalized intestinal dysmotility did not show any improvement after surgery. Conclusions: Preoperative physiologic testing reliably identified patients with severe constipation who might have benefits from surgery. If cases are carefully diagnosed and selected, the surgical treatment may be highly effective in alleviating symptoms. (Korean Journal of Gastrointestinal Motility 2001;7:204-215)

본 연구는 겨울철 파프리카의 안정된 영양생장, 생식생장을 파악하는 방법으로 간이영양진단기기를 이용해 NO₃- 농도를 신속하게 측정하고 영양상태 파악을 위해 실시되었다. ‘Raon red’, ‘Raon yellow’ 두 품종을 각각 비대기 단계로 나누어 측정한 결과 엽신의 test strip 분석은 분광광도계를 통한 관행의 방법과 상관성이 인정되었고(R²=0.8628), 엽병의 test strip분석은 엽신 즙액 보다는 낮은 상관성을 보이지만 간접적으로 NO₃- 농도 분석에 유용하였다(R²=0.6734). 착과 그룹이 높아짐에 따라 해당 부위 엽 내 질산태질소 농도가 낮아지는 경향을 보이고 있으며, 동일 시점의 마디별 엽병 즙액 내 질산태질소 농도 역시 정단부로 갈수록 낮아지는 경향이 확인되었다. 엽병 즙액 내 NO₃- 농도 역시 간이진단기기를 활용하여 신속한 모니터링이 가능하였다. 따라서 간이영양진단기기를 사용해 기존 분석방법보다 효과적으로 농가 현장에서 파프리카의 질소 영양상태를 파악할 수 있었으며, 이를 통해 추후 합리적인 양액공급 및 표준영양범위의 설정이 가능할 것으로 판단된다. This research was aimed to establish rapid analysis technique for the determination of nitrate (NO₃- ) concentration in the leaves of paprika, which has key role for the stable vegetative and reproductive growth. Leaf petiole and blade sap of two paprika cultivars (‘Raon red’ and ‘Raon yellow’) were used for the determination of NO₃- concentration, separately using rapid detection kit (RQ-flex) and spectroscopy quantification methods. In addition, two paprika cultivars namely, ‘Nicole’ and ‘TP2001’ were used to determine the status of NO₃- concentration in leaf of each fruiting group. NO₃- concentration in leaf blade sap and the content in leaf showed significant correlation (R² = 0.8628), analysed by RQ-flex and spectroscopy methods, respectively. Furthermore, leaf petiole sap and the content in leaf also showed significant correlation (R²=0.6734) but the relationship was poor compared to leaf blade sap and the leaf content. NO₃- concentration in petiole sap decreased in all the cultivars from early to late fruiting group. The higher concentration in the lower leaves and the continuous decrease towards the upper leaves in the both years were found through the analysis of NO₃- concentration in different leaf position. In addition, daily short-term fluctuation of NO₃- in petiole sap could be rapidly monitored. These results showed that long-term or short-term monitoring by test strip-based rapid analysis technique might be useful tool for the diagnosis of nutritional status for the stable of nutritional management in paprika.

본 연구는 서낙동강 유역 평강천의 수질을 분석하고 이 하천수의 대체 용수원으로 지하수나 빗물이 가능한 지를 검토코자 수행되었다. 평강천의 염 농도(EC)는 계절에 따라 차이가 컸으며 갈수기인 3월~5월에는 EC 3.22~3.62dSㆍm?¹로 매우 높았고 성수기인 6월부터 점점 낮아져 9월에는 EC 2.37dSㆍm?¹까지 낮아졌다. 염 농도(EC)는 평강천의 위치에 따라 많은 차이를 보여 상류는 EC 0.71dSㆍ?¹, 중류는 2.38dSㆍm?¹, 하류는 3.02dSㆍm?¹ 였다. 초장, 생체중, 건물중 등 생육이 토마토, 오이 모두 하천수보다 빗물이나 수돗물에 좋았다. 평균과중은 토마토는 수돗물이 가장 무거웠으나 오이는 처리간에 유의차는 없었다. 착과수는 토마토, 오이 모두 하천수가 가장 적었으며 빗물과 수돗물 간에는 차이가 없었다. 수량은 토마토에서는 수돗물이 10,594㎏/10a으로 가장 많았으며 빗물, 하천수 순이었다. 오이는 각각 수돗물이 11,826, 빗물이 10855㎏/10a로 하천수보다 44, 33%많았다. 토마토 과실의 품질에서 당도는 하천수가 다소 높은 경향이었으나 처리간에 차이가 없었으며 배꼽썩음과의 발생은 하천수가 가장 많았다. T-N 및 P의 함량은 토마토, 오이 모두 처리간에 차이가 없었으며 Ca 함량은 토마토에서는 하천수보다 빗물이나 수돗물이 많았고 오이에서도 같은 경향이었다. 반면 Na 함량은 Ca와 달리 하천수에서 가장 많았다. 이상의 결과에서 서낙동강 유역의 농업 용수원으로 하천수 대신 지하수나 빗물을 이용하면 토마토 생육에 효과적일 것이라 생각된다. This study was conducted to analysis the chemical properties of Peunggang river and investigate the effect of irrigation sources on the growth of tomato and cucumber. The salt concentration in Peunggang river was high by 3.22~3.62 dSㆍm?¹s from March to May and lower gradually from April to February of next year, which was also lower in upper stream than in middle or low stream of Peunggang river. The growth such as plant height, fresh weight and dry weight in tomato and cucumber was better in drain water and tap water irrigation than in PR water (Peunggang river) irrigation. Mean fruit weight was highest in the tap water, and that of cucumber was no significance in the treatments. The number of setting fruit was lower in the PR water than in the treatments, and which was no significance between rain water and tap water. The yield of tomato and cucumber was found to be highest by 10,594 and 11,826 ㎏/10a in tap water, respectively and also lowest in the PR water among the three treatments. The fruit quality, soluble solids of tomato shows a tendency to increase in the PR water as compared with the other treatment, and the rate of blossom-end rote was higher by 13.6% in the PR water. T-N and P content of tomato and cucumber were no significance in the treatments. Ca content was lowest, but Na content highest in the PR water. It was thought that a rain water and tap water as alternative irrigation source of a PR water were proper.

A new appraisal of the management of acute aortic dissection is timely because of recent developments in diagnostic strategies (including biomarkers and imaging), endograft design, and surgical treatment. These have led to a better understanding of the epidemiology, risk factors, and molecular nature of aortic dissection. Although open surgery is the main treatment for proximal aortic repair, the use of endovascular management is now established for complicated distal dissection and distal arch repair and has recently been discussed as a pre-emptive measure to avoid late complications by inducing aortic remodeling.
