Multiple bilobar liver matastases (MBLM) are the main cause of low resectability in the colon cancer liver metastases. The authors experienced one case of initially non-resectable colon cancer liver metastases. He was curatively and safely treated with a two-stage hepatectomy using the new method of future remnant liver volume growing. A 54-year-old man was referred to our department with the sigmoid colon cancer combined with MBLM, which were checked in two small metastatic lesions in the left lobe and five large sized lesions in the right lobe in the computed tomogram (CT). A laparoscopic assisted anterior resection was primarily performed. We performed the 1^(st) stage hepatectomy 3 weeks after the colon resection. Intra-operative Ultrasonogram (US) found 9 small superficial metastatic lesions in the left lobe. All that lesions were completely removed by non-anatomical wedge resection. An occlusion ballon catheter was placed in the right portal vein through a small branch of the inferior mesenteric vein at that time. The future remnant liver volume was sufficiently increased 3 weeks after the 1^(st) hepatectomy. A right hepatectomy was safely performed 22 days after the 1^(st) hepatectomy. The patient received a regional chemotherapy (interleukin2 based immuno-chemotherapy through hepatic artery) for 4 months, then received 9 cycles of systemic chemotherapy (biweekly Oxaliplation, leucovorin, plus 5-fluorouracil) without any recurrence evidence.

Tooth transposition is an anomaly of eruption characterized by the interchanged positions of two adjacent teeth, which is divided into complete and incomplete transposition. There are three common approaches for treating transposition: aligning the involved teeth in their transposed positions, moving them to their correct anatomic position in the arch and extracting one of the transposed teeth. Considerations in treatment plans are esthetic, function, risk of jeopardizing the roots and damaging the supporting structures, position of the root apex, developmental stages of teeth and expected compliance. The presented case reports described one maxillary canine-the first premolar transposition and two mandibular lateral incisor-canine transpositions. The former transposed teeth were arranged in their transposed position, and the latter transposed teeth were rearranged into their normal position. 치아전위란 인접한 두 치아의 위치가 서로 바뀐 치아 위치 이상을 말하며, 치관과 치근의 위치에 따라 완전전위와 불완전전위로 나눌 수 있다. 하악보다는 상악에 편측성으로 호발하며, 특히 상악 견치에서 자주 발생한다. 전위는 발견 시기와 전위된 양상에 따라 치료방법이 달라질 수 있다. 본 증례는 상악 견치와 제1소구치 간의 전위가 일어난 10세 7개월의 환아와 하악 측절치와 견치 간의 전위가 일어난 8세 11개월 환아와 8세 9개월 환아의 교정치료에 대한 것으로 양호한 치료 결과를 얻었고, 증례 별로 치료방법의 차이점에 관한 고찰을 하였기에 이를 보고하는 바이다.

본 연구에서는 유치 수복물의 불소 방출 여부에 따른 주변 법랑질의 탈회 저항성과 재광화 효과를 살펴보고자 하였다. 건전 유전치 48개를 16개씩 임의로 세 군으로 나누어, FiltekTM Z250(1군), F2000(2군), KetacTM N100(3군)을 사용하여 제조사의 지시에 따라 충전하였다. 3일 동안 인공 우식 병소를 유발한 후, 14일 동안 인공 타액에 담가 재광화를 유발하였다. Quantitative light-induced fluorescence(QLF)를 이용하여 실험 단계와 시간에 따른 무기질 소실량(ΔQ)의 변화를 관찰한 결과는 다음과 같다. 1. 탈회가 일어난 인공 우식 병소의 ΔQ 값은 3군, 2군, 1군 순으로 작게 나타났고, 이 중 3군은 1군에 비해 유의한 탈회 저항성을 보였다. 2. 1군, 2군, 3군 모두 재광화 1일 후부터 초기 인공 우식 병소의 ΔQ 값과 비교 시 유의한 차를 보였으며, 관찰 기간 동안 지속적인 증가 양상을 나타내었다. 3. 재광화 속도를 의미하는 Δ(ΔQ)/일 값은 각 군에서 처음 1일 동안 유의성 있게 크게 나타났으며, 그 이후 급속히 감소하였다. 4. 수복 재료에 따른 재광화 정도는 각 군 간에 유의한 차이가 없었다. The objective of this in vitro study was to detect and monitor demineralization and remineralization of primary teeth according to restorative materials using quantitative light-induced fluorescence (QLF). A single bur hole was drilled on the each sound forty eight primary anterior teeth, and the specimens were divided into three groups. The cavity was restored with FiltekTM Z250(Group 1), F2000(Group 2), KetacTM N100(Group 3) following the manufacturer's instructions. The teeth were subjected to the demineralizing buffer for 3 days, and then subjected to a remineralizing buffer for 14 days. The change of mineral loss(ΔQ) according to the stages was evaluated by QLF and the following results were obtained: 1. When demineralization was done, ΔQ was increased as follows. : Group 1 (-110.79 ± 27.77) < Group 2 (-104.84 ± 28.95) < Group 3 (-90.16 ± 21.87) : Resistance to demineralization was statistically significant in Group 3. 2. There was a statistically significant increase in ΔQ of all groups since 1st day of remineralization 3. The rate of remineralization, Δ(ΔQ)/day, showed significant high value in each group on the 1st day then decreased rapidly. 4. There was no statistically significant difference in the degree of remineralization among restorative materials.

Developmental anomalies of the aortic arch, commonly known as vascular rings, are relatively rare congenital vascular anomalies which can compress the trachea and esophagus. One routine chest film of a patient who was checked and hepatoma-diagnosed in Internal Medicine, Chosun University Hospital left the room for doubt of mediastinal mass. But no subjective symptoms for the mass was told by the patient. This is to report our experience of a patient having right side aortic arch with aberrant left subclavian artery, as proved by diagnosis, but none of congenital heart disease. This right side aortic arch with aberrant left subclavian artery is the most frequent type among right aortic arch, the anomaly of which is usually detected from the incidental suspicion for mediastinal mass at routine chest film; because no symptoms are accompanied therewith.

Weak points of the current hazard analysis and the importance of pre-requisite program operation

Chong Hae Hong 한국예방수의학회 2018 예방수의학회지 Vol.42 No.2

Food hazards caused by Hazard Analysis Critical Control Point(HACCP) products are closely related to the failure of prerequisite program. ISO 22000 introduced the Operational Prerequisite Program (OPRP) to enhance management of the prerequisite program. This program has started to strengthen discriminatory management of hazards identified as high in risk analysis but not selected as Critical Control Points. In addition, the US-FDA has begun to apply Food Safety Modernization Act (FSMA) obligations to all foods manufacturing and distribution including imported foods. The basic concept of the FSMA is Hazard Analysis and Risk-based Preventive Control (HARPC), which is similar to the OPRP. It is necessary to strengthen the management of the prerequisite program by using the OPRP or HARPC concept, which will improve the effectiveness of HACCP operation.

Control measures to achieve food safety objectives

SPS 협약에서는 자국의 국민 및 동식물의 건강보호를 위해서 ALOP 범위내에서 예방조치를 허용한다. 이에 따라 국가는 FSO 를 설정하고 자국민 보호를 위한 안전관리 정책을 수행할 수 있다. FSO에 명시되는 구체적인 목표치는 관리우선순위가 높은 특정식품과 특정 위해요소에 국한되지만, 현행 식품안전관리 시스템의 전반적인 내용을 점검하고 개선하는 계기가 되어 관련법규, 제도, 기업환경, 소비자 인식제고 등 폭넓은 분야에서 실효성 있는 개선이 이루어질 수 있다. FSO 달성을 위해서는 농장에서 식탁에 이르는 각 단계에서 PO를 설정하고 PC에 의한 실효성 있는 통제가 요구되는데, HACCP-like system은 그 중요한 역할을 수행할 수 있을 것이다. Foreign hazardous substances are likely to enter the country through imported foods as food trade between countries increases. The Sanitary and Phytosanitary Agreement allows countries to take preventive measures to protect the health of the people based on the Appropriate Level of Protection (ALOP). Thus, the country may establish its own food safety objective within the scope of the ALOP and implement more efficient food safety management system to achieve food safety goal. Therefore, more stringent control measures such as Hazard Analysis and Critical Control Point (HACCP) like systems should be applied to set and meet performance objectives at each stage of the food chain.

Re-evaluation of critical control point configuration for non-thermal process such as meat packaging plant and butcher shop

Chong-Hae Hong 한국예방수의학회 2017 예방수의학회지 Vol.41 No.2

Reanalysis using the US Food and Drug Administration Hazard Analysis method was performed to evaluate the effectiveness of the current Critical Control Point (CCP) configuration for non-thermal processes such as meat packaging plants and butcher shops. During non-heat treatment processing without the process of removing or reducing contaminated microorganisms, it is necessary to set and control the incoming material inspection step with the CCP since this step is essential to prevent the inflow of contaminants through incoming materials. The temperature control of the final product storage refrigerated room can be managed by the prerequisite program. However, the CCP setting of the refrigerated room prior to shipment of the meat packaging plant in which the cold chain system should be maintained in the following distribution stage is recognized. It is not an effective method to install a metal detector and manage it with CCP for metal hazard control. Improving hygienic cleaning guidelines and enhancing hygiene training are proactive and effective measures against metal particle contamination.
