Hepatic arterial infusion chemotherapy (HAIC) is performed in patients with advanced hepatocellular carcinoma (HCC) in which locoregional therapeutic methods such as transarterial chemoembolization (TACE), percutaneous ethanol injection (PEI) or radiofrequency ablation (RFA) could not be the best choice. Sorafenib, the only approved systemic chemotherapeutic agent for HCC, improves survival rate, but is associated with a low tumor response rate. Thus combining these therapeutic modalities to treat HCC in advanced stage may help downstaging and leading to better treatment results without taking risk for hepatic failure. Here we report a case treated to a complete remission by combining HAIC, PEI and sorafenib.

Bone metastases in hepatocellular carcinoma (HCC) are usually treated with non-operative procedures such as radiotherapy, hormonal therapy, bisphosphonates, or sometimes with surgical procedures. Here we describe a case with 3rd cervical spine metastasis of HCC. A 62-year-old female with liver cirrhosis presented with neck pain. After evaluation, the patient was diagnosed of hepatocellular carcinoma with cervical spine metastasis. The metastatic lesion was treated with tomotherapy while the primary lesion in the liver was treated with transarterial chemoembolization using drug-eluting beads, and the patient is tolerable waiting for the next treatment.

A field study was conducted over a 3-year period from 2014 to 2016 in the central plain area, Suwon, Korea, 1) to compare the biomass production between machine-transplanted and water-broadcast seeded silage rice and 2) to elucidate the growth factors that affect the difference in biomass production between the two cultivation practices. The heading date for the water-broadcast seeded silage rice was September 11-18, which was delayed by 11-17 days when compared to that for the machine-transplanted silage rice. On average, water-broadcast seeded silage rice had a shorter plant height, more panicles per area, and a greater biomass production because of the increased straw dry weight. However, the difference in dry weight of each plant organ between the two cultivation practices exhibited yearly variation. When the data were pooled across experimental years, cultivation practices, and varieties, biomass production was highly positively correlated with straw dry weight but not with panicle dry weight. When the ratio of water-broadcast seeding to machine-transplanting was analyzed, total dry weight and straw dry weight were positively associated with each other, whereas no relationship was found between total dry weight and panicle dry weight. Despite that water-broadcast seeded silage rice produced more panicles per area than machine-transplanted silage rice, the two cultivation practices had a similar dry weight per culm. Therefore, we conclude that the silage rice from the water-broadcast seeding, compared to the machine-transplanting, produced more biomass because of the combination of the increased panicle number per area and a similar dry weight per culm. These results suggest that silage rice could be produced through water-broadcast seeding to increase biomass production with low labor and cost input.

불완전미가 식미에 미치는 영향을 알아보기 위하여 현미외 관별로 백미 품위를 구분하고 각각의 불완전미를 완전미와 혼입하여 근적외분광광도계를 이용하여 식미치를 검토한 결과는 다음과 같다. 가. 수확한 현미의 정상립은 $75.7\%$였으며, 불완전렵은 변색립이 $11.0\%$, 청미가 $8.0\%$, 그리고 사미가 $5.3\%$였다. 나. 정상립 현미에서 도정된 백미는 완전미가 $64.7\%$였으며, 동할미가 $25.3\%$, 심복백미가 $10\%$였으며, 변색립 현미는 정상립에서 도정된 백미외관과 큰 차이가 없는 것으로 나타났다. 청미는 완전미가 $36\%$, 심복백이 $64\%$였으며, 사미는 심복백미가 $25.3\%$, 유백미가 $74.7\%$였다. 다. 백미 품위에 따른 식미관련 특성 검정 결과, 동할미의 점도는 정상미와 차이가 없었으나 심복백미의 점도는 정상립 보다 약간 낮았고 유백미의 경우는 정상립의 $60\%$ 수준으로 감소하였다. 단백질 함량은 심복백미와 유백미가 정상립보다 다소 높게 나타났다. 라. 기계적 식미치는 불완전립 모두 정상립 보다 현저히 낮게 나타났다. 불완전미 중 유백미와 심복백미는 완전미에 $1\%$만 함유되어도 완전미 대비 약 $5\%$의 식미가 감소되었으며, $5\%$ 함유되었을 경우에는 완전미 식미에 비하여 유백미는 $20\%$, 심복백미는 $12\%$의 식미치가 감소되었다. 그러나 동할미의 경우는 $5\%$까지는 식미치에 크게 영향이 없었다. 오히려 잔디의 밀도가 감소되는 경향을 보였다. 초장의 경우 복비의 무처리시 거의 잔디의 초장이 신장하지 않았으며, 오히려 감소하는 경향을 보였다. 반면, 잔디의 피해지역에 복비를 처리할 경우 잔디의 빠른 생장이 이루어졌다. 신초 건물중은 복비 처리전 8월 6일에 비하여 11월 6일에 이스트밸리 LD지역의 무처리구가 $1.2\%$감소하였지만 처리구는 $50\%$정도가 증가하였다. 지산의 시험 결과도 이스트밸리와 유사하였다. 신초와 뿌리의 비율(S/R)은 처리구의 경우 뿌리보다 신초의 건물중이 더 증가하였지만, 무처리구의 경우 뿌리와 신초의 생장율이 거의 비슷하였다. 포복경과 지하경의 건물중을 합한 R&S의 건물중을 조사한 결과, 이스트밸리의 경우 복비를 처리하기 전 8월6일에 무처리구인 LD지역이 처리구인 LD지역에 비하여 $5.5\%$정도가 적었지만 복비를 처리한 후엔 오히려 처리구의 LD지역이 $48\%$로 증가하였다. 지산의 결과 역시 이스트밸리와 유사하였다. 4. 이상의 결과들로 알 수 있는 것은 수목 근부에 생장하고 있는 잔디의 피해 요인들은 여러 가지가 있지만, 골프장내 수목의 밀생 지역이 아닌 경우에는 광에 의한 피해보다는 오히려 양분과 수분의 경쟁에 의한 피해 발생 비율이 크다. 따라서 이들 잔디의 피해 지역에 복비를 처리함으로서 무처리 지역에 비하여 상당히 많은 효과를 보았기 때문에 수목 근부에서 생장하는 잔디의 집중관리 체계로 보다 효율적인 코스관리에 도움이 될 수 있을 것으로 기대된다.ting이 관찰되는데, 진성기업의 Stainless Steel은 가늘고 긴 압흔이 있으며 비교적 매끄러운 표면을 보이고, Unitek사의 경우 압흔과 함께 pitting 이 관찰되며, Ormco Stainless Steel의 경우 불규칙한 pitting이 다 This experiment aimed to estimate the effect of imperfect rice on rice palatability. Rice cultivar, Ilpumbyeo, was cultivated by direct-seeding on flooded paddy surface with 11 kg/10a nitrogen application. Palatability of harvested rice was measured by NIR spectroscope. Brown rice was divided according to their appearance namely, perfect, discolored, green-kerneled, and immature opaque with a composition ratio of $75.7\%,\;11.0\%,\;8.0\%,\;and\;5.3\%$ respectively. When the perfect brown rice was milled, the grain were composed of head, cracked, and white core & belly, at $64.7\%,\;25.3\%\;and\;10.0\%$ respectively. The milled rice of discolored brown rice had similar composition with the perfect rice. The milled green-kerneled vice, on the other hand, had $36\%$ head rice and $64\%$ white core & belly rice. The immature opaque brown rice, when milled, had $25.3\%$ white core & belly and $74.7\%$ damage & opaque rice. With the respect to grain quality, the viscosity of white core at belly rice and damaged & opaque rice was lower than that of head rice. In contrast, their protein content was a little higher than that of head rice. The palatability value of pure imperfect rice was much lower than head rice. The palatability value of damaged & opaque rice was the lowest among the imperfect rices. When mixed with head rice, the damaged & opaque rice impacted on the deterioration of vice palatability. Mixing $1\%$ each of white core at belly rice and damaged h opaque rice decreased the palatability value by $5\%$ as compared with the head rice.

This study was carried out in 2014 and 2015 to investigate the effect of transplanting density on panicle production and to analyze the relationship of panicle production with yield traits in the mid-maturing quality rice cultivar 'Haiami' in the mid-plain area of Korea. Number of tillers per square meter increased by reducing planting distance and increasing seedling number per hill. These effects were maintained until maturity and were reflected in the final number of panicles per square meter, although the effect of planting density decreased as rice growth progressed. However, increased panicle number per square meter following dense planting did not improve head rice yield. Panicle number per square meter was negatively associated with spikelet number per panicle and was not correlated with other yield components or head rice yield. Head rice yield was not correlated with head rice percentage but was closely and positively correlated with milled rice yield. Milled rice yield did not increase with grain filling percentage but increased with spikelet number per square meter. Spikelet number per square meter increased with both spikelet number per panicle and panicle number per square meter, although the former had a greater influence. Therefore, we conclude that head rice yield of the 'Haiami' cultivar grown in the mid-plain area of Korea is not improved with an increased panicle number following high planting density but it could be improved with high milled rice yield by increasing spikelet number per unit area.
