This paper tried to find various ideas for the purpose of increasing the demand for domestic bean which is the main raw material of bean curd products. To accomplish this objective, purchasing behavior of the current consumers were surveyed and the consumer evaluation of the products were investigated. Using experiment conjoint analysis, consumers' marginal willingness to pay for several important attributes of the products were derived. Among the attributes analyzed, the origin of the material bean turned out to be the most important attributes of all.

The induction of mutants using a variety of mutagens provides new genetic resources for crop breeding. In the current study, we generated mutants in sorghum using gamma-ray treatment and conducted transcriptome analyses between a mutant line and its origin. Based on the data generated by the analysis, we predicted genes that were differentially expressed in the mutant compared to its origin and identified their functions. Gene Ontology and KEGG pathway were performed to annotate DEGs functions. Furthermore, we constructed gene co-expression networks to demonstrate the association of the identified transcription factors. We also searched for single-nucleotide polymorphisms (SNPs) and insertions/deletions (InDel) which can possibly cause the alteration of gene functions. The SNP data discovered in this transcript analysis found 11 genes that appeared in common with co-expression networks and examined the associations for salt-responsiveness. This study provides genetic backgrounds that can emerge when sorghum is subjected to gamma irradiation to progress the mutant.

A case of Kawasaki disease with coexistence of a parapharyngeal abscess requiring incision and drainage

최세현,김현정 대한소아청소년과학회 2010 Clinical and Experimental Pediatrics (CEP) Vol.53 No.9

Kawasaki disease (KD) causes multisystemic vasculitis but infrequently manifests with deep neck infections, such as a peritonsillar abscess,peritonsillar or deep neck cellulitis, suppurative parapharyngeal infection, or retropharyngeal abscess. As its etiology is still unknown,the diagnosis is usually made based on typical symptoms. The differential diagnosis between KD and deep neck infections is important, considering the variable head and neck manifestations of KD. There are several reports on KD patients who were initially diagnosed with retropharyngeal abscess on on computed tomography scans (CT). However, the previously reported cases did not have abscess or fluid collection on retropharyngeal aspiration. Therefore,false-positive neck CT scans have been obtained, until recently. In this case, suspected neck abscess in patients with KD unresponsive to intravenous immunoglobulin could signal the possible coexistence of suppurative cervical lymphadenitis.

Purpose High-dose radioiodine treatment (HD-RIT) after injection of recombinant human thyroid stimulating hormone (rh-TSH) has become widely used. This study compared the therapeutic efficacy of HD-RIT and clinical parameters between rh-TSH supplement and thyroid hormone withdrawal (THW) after total thyroidectomy in patients with differentiated thyroid cancer. Methods We retrospectively reviewed 266 patients (47 male and 219 female; age, 49.0±10.9 years) with differentiated thyroid cancer detected from September 2011 to September 2012. Patients comprised THW (217, 81.6 %) and rh-TSH (49, 18.4 %). Inclusion criteria were: first HD-RIT; any TN stage; absence of distant metastasis. To evaluate the complete ablation of the remnant thyroid tissue or metastasis, we reviewed stimulated serum thyroglobulin (sTg), I-123 whole-body scan (RxWBS) on T4 off-state, and thyroid ultrasonography (US) or [F-18]-fluorodeoxyglucose positron emission tomography/computed tomography (F-18 FDG PET/CT) 6–8 months after HD-RIT. We defined a complete ablation state when all three of the follow-up conditions were satisfied; <2.0 ng/ml of the sTg, I-123 RxWBS (−), and thyroid US or F-18 FDG PET/CT (−). If one of the three was positive, ablation was considered incomplete. We also compared various clinical biomarkers (body weight, body mass index, liver and kidney function) between THW and rh-TSH groups. Results The rates of complete ablation were 73.7 % (160/217) for the THW group and 73.5 % (36/49) for the rh-TSH group. There was no significant difference between the two groups (p=0.970). The follow-up aspartate transaminase (p=0.001) and alanine transaminase (p=0.001) were significantly higher in the THWgroup. The renal function parameters of blood urea nitrogen (p=0.001) and creatinine (p=0.005) tended to increase in the THW group. The change of body weight was + Δ0.96 (±1.9) kg for the THW group and was decreased by -Δ1.39 (±1.5) kg for the rh-TSH group. The change of body mass index was 0.4 (±0.7) kg/m2 in the THW group and was decreased by −0.6 (±0.6) kg/m2 in the rh-TSH group. Conclusions Consistent with previous studies, the rates of complete ablation between the THWand rh-TSH groups were not significantly different. The clinical parameters, as we mentioned above, were elevated for THW group but were irrelevant for the rh-TSH group. The findings favor HD-RIT after rh-TSH, especially for patients with chronic liver and kidney disease.

The number of species and density of benthic polychaetes increased rapidly before (33 species, 63 ind./㎡ in 2005) and after (45 species 107 ind./㎡ in 2008, 71 species, 527 ind./㎡ in 2009) the oil pollution accident in the subtidal zone of Taean. The dominant species and environmental factors (grain size, ignition loss, salinity, dissolved oxygen, water temperature) were analyzed as a significant correlation. Benthic pollution index was high in the south subtidal zone of Taean before the oil pollution but then it was highly analyzed in the north subtidal zone.

열성경련 재발 예방을 위한 저용량 경구 diazepam 요법의 효과

최세현,박호진 대한소아신경학회 2012 대한소아신경학회지 Vol.20 No.2

Purpose : This study was aimed to investigate the optimum dose of diazepam to reduce the recurrence of febrile seizures and side effects in children with febrile seizures. Methods : The subjects of this study included 528 children with febrile seizures (3 months-5 years of age) who were admitted to Eulji University Hospital (Daejeon, Korea) from January 2008 to December 2011. The children divided into four groups according to the dose of diazepam; Group I, 121 patients, received no diazepam therapy, group Ⅱ, 129 patients, received oral diazepam in a single dose of 0.1 mg/kg after the febrile seizures, group Ⅲ, 127 patients, 0.2 mg/kg, and group Ⅳ, 151 patients, 0.3 mg/kg, respectively. Results : Seizures recurred in 6 of 129 children (4.7%) in group Ⅱ, 1 of 127 children (0.8%) in group Ⅲ, and none of 151 children in group Ⅳ recurred. For the 121 untreated patients, febrile seizures recurred in 20 (16.5%) children. This study revealed a significant difference in the rate of recurrence of febrile seizures between children treated with diazepam and those who were not. And the recurrence rate was decreased by the increment of the dosage of diazepam, but there was no significant difference between groups. The side effects were observed in 19.9% of children treated with diazepam, 3.9% in group Ⅱ, 12.6% in group Ⅲ, and 39.7% in group Ⅳ, The rate of side effect was also increased with the increment of the dosage. Conclusion : An oral diazepam therapy will reduce the incidence of recurrent febrile seizures during the same febrile illnesses. We think the optimum dose of diazepam is 0.1 mg/kg or 0.2 mg/kg rather than 0.3 mg/kg. However, the use of oral diazepam after a febrile seizure should be carefully considered with weighing the benefits and potential adverse effects.

최세현,최태길,이상학,이한성 한국자료분석학회 2009 Journal of the Korean Data Analysis Society Vol.11 No.3

Economic analysis of a public project requires benefits and costs of the project to be valued and compared. However, there are benefits or costs that are difficult to identify and evaluate. Nonmarket goods such as historic and cultural properties are a good example. This study tried to estimate the historic and cultural properties adjacent to Danghang Bay in Gosung Area. Surveys were conducted based on contingent valuation method(CVM) and the data of 300 local respondents were obtained. Using Turnbull model, the annual value of the historic and cultural properties adjacent to Danghang Bay in Gosung Area to the nearby Gosung residents was estimated to be 25,152won per person and about 1,393 million won in total. 공공사업의 경제적 분석을 위해서는 사업의 편익과 비용이 가치화되고 비교되어야 한다. 그러나 편익 또는 비용 항목들 중에는 그 확인과 가치화가 어려운 것들이 존재한다. 역사·문화재는 그 시장이 존재하지 않는 비시장재화로 일반적인 경제이론으로는 가치화하기가 어려운 재화이다. 본 연구에서는 정부에서 추진하는 마동지구 용수개발사업으로 인하여 훼손될 가능성이 있는 고성군 당항만 연접지역의 역사·문화재 가치의 추정을 시도하였다. 이를 위하여 고성군 지역 주민들을 대상으로 조건부가치평가법(CVM)을 위한 설문조사를 실시하였고, 300개의 표본을 얻을 수 있었다. Turnbull 모형을 사용하여 분석해 본 결과 고성군 당항만 연접지역의 역사·문화재의 가치는 고성군 주민들에 한하여 1인당으로는 월 2,096원, 연 25,152원, 전체로는 월 116백만원, 연 1,393백만원으로 추정되었다.

To help improve the current government practice of direct damage-compensation policies, resulting from the loss of profit, sustained by Hanwoo farmers, as a result of the recent Korea-U. S. Free Trade Agreement (FTA), this research aims to examine any problems or issues caused by said policies. To accomplish this task, we have established Hanwoo-SIMO model and estimated the damage of Hanwoo farmers, one without the implementation of the FTA and another with the FTA, to compare and contrast the two. We then analyzed the efficacy of the current government policies. According to our analysis, the current direct compensation policies for the loss of profit on the part of Hanwoo farmers are insufficient. To address this problem, we recommend the government enact a new direct damagecompensation law to address the following issues. First, as the base formula of damage-compensation, the government should use current price of the beef rather than the annually changing flexible price. Second, the flexible control index should remain fixed at 1.0 rate while the government prepares the adequate amount of the damage compensating direct payment resulting from the FTA. Third, the direct government compensation policy should extend beyond the current 15 years (2013-2026) as the profit loss is expected to increase after the midpoint of the FTA.
