Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

본 연구는 마산만 저질과 패류(바지락)틀 채취하여 중금속 함량을 측정함으로서 마산만의 중금속에 의한 오염현황을 파악하고자 하였다. 전반적으로 저질의 평균농도는 Zn, Pb, Cu, Cr, Cd의 순으로 각각 109.54, 26.01, 22.41, 15.99, 0.20㎍/g이었으며, 바지락의 평균농도는 Zn, Cu, Cr, Pb, Cd의 순으로 각각 19.44, 0.7, 0.49, 035, 0.07㎍/g으로 나타났다. 각 지점별 저질의 중금속 농도는 S1 지점과 S6 지점에서 높은 함량을 보였으며 패류의 경우 S1지점에서 높은 경향을 보였다. 저질과 패류의 함량 비교에 있어 Zn, Cu, Pb의 경우 저질의 함량이 패류외 함량에 어느정도 영향을 미치고 있음을 알 수 있었으나, Cr과 Cd의 경우 저질과 패류간의 뚜fut한 상관관계성을 볼 수 없었다. The purpose of this study was investigate the heavy metal contents in sediment and shellfish samples in Masan Bay on May 1993. Atmospheric absorption spectrophotometric results showed that the mean values of the mean value of the heavy metal contents detected from sediment samples were very high in the order of Zn(109.54㎍/g), Pb(26.01㎍/g), Cu(22.41㎍/g), Cr(15.99㎍/g), Cd(0.2㎍/g), and that the metals in shellfish samples were also high in the order of Zn(19.44㎍/g), Cu(0.7㎍/g), Cr(0.49㎍/g), Pb(0.35㎍/g), Cd(0.07㎍/g) in general. The metal levels in sediments from Nampo(S1) and Bongam(S6) and that in shellfishes from Nampo(S1)were high in concentration compared with those of the other sites. The higher residue levels uf Zn, Cu, and Pb in both the sediments and shellfishes suggested that the metal levels in shellfishes might be affected by the metal contents in sediments to some extent, although there was no certain correlation between the residue contents of Cr and Cd in sediment and shellfishes.

The sediments in the study area are subdivided into twelve textural classes, namely clayey sand, slightly gravelly muddy sand. muddy sand, sand, sandy mud, sandy clay, mud and clay. The coarse sediments are distributed in the southeastern parts and around the Island. whereas the coarse and fine-grained mixed sediments are distributed in the central and northeastern region, and the fine-grained deposits are mainly distributed in the western part of the study area. Small scale mud patchs are distributed in the southwestern. and northern parts of the Island. The carbonate content(21.6% on average) are commonly abundant in sandsize sediments. whereas total organic matter(6.62% on average) are usually decreases with increasing mean grain size. The use of Pb-210 geochronologies to estimate sedimentation rate ranges from 0.20 to 0.54 cm/yr or 0.15~0.42 g/㎠/yr. This suggests a maximum accumulation rate in the study region given ignoring the mixing effect. The sedimentation rates in cores J-101 and J-134 near the Changjiang River estuary show 0.45~0.54 cm/yr. and the flux of Pb-210 in this region is 1.48~2.31 dpm/㎠/yr. but two core J-138 and J-142 far from the Changjiang estuary show 0.20-0.22 cm/yr and 0.36-0.57 dpm/㎠/yr respectively, which is much lower than above two samples. The decrease in accumulation rate with increasing water depth may be result of progressive seaward depletion of influx and reworking of detrital materials. The sedimentation rate in cores J-59 and J-91 around the Cheju Island show 0.21~0.44 cm/yr and the Pb-210 flux of 0.84-1.44 dpm/㎠/yr is measured. indicating that the terrigenous materials from the Island were supplied to this environment. The sedimentation rate measured using two peak concentration of Cs-137 in a sediment profiles J-59, J-13 and J-142 ranges from 0.12 to 0.30cm/yr. which agree well the Pb-21 calculated data 0.20-0.22cm/yr from that at same samples. but a comparison sedimentation rate in cores J-91, J-101 and J-134 measured by Cs-137(0.16-0.30 cm/yr) and calculated from Pb-210(0.44-0.54 cm/yr) show that in the studied core profiles. the Cs-137 survey data underestimate the sedimentation rate measured by Pb-210 data. Its presumably the result of difference in the behavior of Pb-210 and Cs-137 in natural water column. Measurements of magnetic susceptibility of continental shelf sediments around the Cheju Island revealed two areas of anomalously high values: surrounding the Cheju inshore area. due to the influx and reworking of detrital volcanic materials distributed in the Cheju Island. and toward the mouth of Chanjiang River. suggesting due to the iron and steel works in the Changjiang estuary recently. It was observed that low susceptibility values correspond to a high proportion of coarse sediment, whereas high susceptibility values correspond to silt and clay fraction. Down core variation in susceptibility shows a series of maximum and minimum which correlated with horizons of fine-and coarser particles respectively. that can possibly be used to establish a lithostratigraphy.

This study purposes to elucidate the effects of changes in precipitation and tide level on the spring water discharge quantity in Cheju Island. For this purposes. local and seasonal variations of discharge quantity have been measured at representive 19 springs covering the entire Island. In the middle mountain region, the discharge quantity is largely influenced by the precipitation, but it has a little relationship with the precipitation in the western region and the southern region. In the eastern region, influence of tide is larger than the precipitation, and the northern region is influenced by both precipitation and tide. In the entire study area, the spring water discharge reaches at maximum in the wet season of July, and shows minimum in the dry season from December to February. The discharge variation in the middle mountain and north regions is two to three times as large as that in the other regions. The comparison of the results of ths study with existing data shows discharge increase at the inch'onk'mul(about 6.000㎥) in the eastern region, Kwakgimul(about 7,000㎥) in the western region, Kangjungchun (about 11.000㎥ : WRDC), Jaguri(about 5,000㎥ : AFDC), Gongchunpo (about 3.000㎥) in the southern region, Yongyeanchun(about 1,500㎥) in the northern region, whde the discharge decrease at Sernurungmul(about 5,000㎥) in the eastern region, Ongpochun(about 10.000㎥) in the western region, Hwasun Dokmul(about 1,500㎥), Kangjungchun( about 28,000㎥ : AFDC), Jaguri(about 43,000㎥ ; WRDC) in the southern region, Sanjimul( about 3.500m3), Oleamul( about 6,200m3) in the northern region. In the Yongyeanchun, tide intimately influences quantity, electrical conductivity, level and temperature of spring water. The spring water in the Yongyeanchun discharges for 17 hours during the hgh tide, then undlscharged for 11 hours during the low tide.

Radiofrequency ablation(RFA), as a form of minimally invasive therapy for hepatocellular carcinoma, has become an important treatment modality. Because of limitation of surgery, RFA has become standard therapy for hepatocellular carcinoma in some situations. But there are some complications of RFA such as bleeding, infection, hematoma, adjacent organ thermal damage including intestinal perforation, needle track seeding, and so on. There are few reports in the literature that systematically evaluate the incidence of needle tract seeding and its associated risk factors. And only 2 cases of needle tract seeding of hepatocellular carcinoma after RFA were reported in Korea. We report a case of needle tract seeding of hepatocellular carcinoma after RFA.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.

Kang, Youn Seok,Sim, Sang Jun,Lee, Dong Hyun,Kim, DukJoon,Kim, Ji-Heung,Lee, Young Kwan,Kim, Woo Sik 한국공업화학회 2003 Journal of Industrial and Engineering Chemistry Vol.9 No.4

This paper is concerned chiefly with the biological removal of natural organic matter (NOM) dissolved in water resources using biological contactor with rope media. The biological treatment represents one option for the removal of NOM from water resource. In this study, we proposed a process including biological contactor with rope media and membrane filtration for the removal of NOM from water resource. We installed three rope media contactors to pilot scale traditional water treatment consisting of preozonation, coagulation, and sedimentation. The average removal yields of dissolved organic carbon (DOC) in biological contactor from raw water and ozonation were 3% and 14%, respectively. The average removal yield of biological contactor from sedimentation tank was 32%, which was much higher than the former case. The heterotrophic plate counts (HPC) value obtained from biological contactor unit reached over 10000 CFU (colony forming unit)/mL, which was five times higher even than that of raw water. However, the HPC could be reduced to below 50 CFU/mL by simple ultra-filtration membrane.
