This study analyzed the effects of nutrition technicians' hygiene education on cooking workers' performance of hygiene management in order to ensure the security of school meals. The situation of cooking workers' disposition in subject schools was elementary school(51.1%) and middle school(48.9%) and the type of meals was rural area type(54.2%), urban type(36.5%), and island and isolated area type(9.3%). The methods of meals management were single cooking(88.2%) and joint cooking and management(11.8%). The type of distributing meals was distributing in a dining room(93.5%), in a classroom(3.7%), and in both dining room and classroom(2.8%). Nutrition technicians' employment form included regular(53.5%) and daily(88.2%). Their education was junior college graduate(50.2%), university graduate(44.8%), and graduate school students(5.0%). Cooking workers' employment form included daily(88.2%) and regular(11.1%), suggesting that most were regular. Most cooking workers(77.4%) had at least high school certificate. Regarding the situation of cooking workers' disposition in subject schools, the number of student per one cooking worker was found as 91-120(37.2%), 61-90(22.6%), 60 and under(21.1%), 121-150(16.7%), and 151 and over(2.5%). Cooking workers' level of performance of hygiene management was post-working stage(66.37/75 marks), pre-working stage(64.22/75 marks), and working stage(20.34/25 marks). The counting of meals articles in a pre-working stage(20.34/25 marks), temperature and required time in a working stage(18.78/25 marks), and machinery equipment and hygiene in a pre-working stage(21.40/25 marks) showed lowest of performance, which suggest poor service of hygiene. Cooking workers' performance of hygiene management by working stage showed the significant difference with school class(p<.001), type of schools with meals(p<.05), state of cooking workers' employment(p<.001), and cooking worker's disposition(p<.05). A working stage showed the significant difference with type of schools with meals(p<.05). A post-working stage showed the significant difference according to type of schools with meals(p<.05), and the methods of meals management(p<.05), and cooking workers' disposition(p<.05). In the execution of hygiene education, individual hygiene was highest(94.8%), followed by the management of machinery equipment and tools(89.7%), food poisoning and microorganism(94.7%), and the method of food treatment(76.4%). A yearly plan of hygiene education included established(83.9%) and not established(16.1%).

이태희,최요원,전석철,서흥석,함창곡,박충기 한양대학교 의과대학 1998 한양의대 학술지 Vol.18 No.2

We evaluated CT findings of the small cell carninoma, which presented as a solitary pulmonary nodule at the periphery of the lung parenchyma. Of pathologically-proven 45 patients with small cell carcinoma, 10 patients was included in this study, who had a solitary, peripheral lung nodule at distal portion of the subsegmental bronchus. We retrospectively reviewed clinical data and CT findings including size, location, margin, enhancement pattern, lymph node enlargement, metastasis. Peripheral small cell carcinomas were 22.2%(10/45). All masses had well-defined margin and lobulated margin was seen in 7 patients. Mean diameter was 3.8cm (2.5-7.0cm). Enhancement pattern were homogeneous in 3 cases and inhomogeneous in seven. Calcification or air-bronchogram was not present, and focal cavitation was seen in one case. In five, only lung mass was present, and lung mass with lymph node enlargement was seen in one. distant metastasis without lymph node enlargement was noted on two patients and another two patients showed lymph node enlargement and distant metastasis. Peripheral small cell carcinoma is not rare(22.2%). Most frequent CT finding is a well-defined, lobulated mass with inhomogeneous enhancement, these findings would be helpful in differentiating small cell carcinoma from other neuroendocrine tumors when differentiataion is difficult cytologically.

文錫哉,文九,金柄住,田炳薰,元秦喜 대한동의병리학회 1997 동의생리병리학회지 Vol.11 No.2

腫瘍으로 인한 死亡率은 多樣한 名種 治療에도 不拘하고 循環器疾患 다음으로 2위를 차지하고 있다. 이에 著者는 韓醫學과 西醫學의 結合治療를 通해서 抗腫瘍藥物의 效果를 增進시키고 副作用을 줄이는 藥物의 開發을 爲하여 健脾 益氣 祛痰 補腎 杭癌效能을 갖고 잇는 扶正杭癌湯抽出液을 使用하여 Colony 形成抑制實驗, Sulforhoda-mine B(SRB) assay를 觀察하였고, 扶正抗癌湯抽出液과 抗癌化學療法劑인 Mitomycin C(MMC)를 Ehrlich carcinoma의 solid tumor와 ascites tumor에 各各 單獨 및 倂用 投與하여 抗腫瘍效果 및 Iysosomal enzymes의 活性에 대한 效果를 觀察하였다. 먼저 扶正抗癌湯抽出液을 Caki-1 cell, Hep 3B 및 A549에 투여한 후 增殖抑制作用을 colony 形成抑制實驗과 SRB assay를 통하여 觀察한 결과 濃度依存的으로 腫瘍細胞의 成長을 抑制하였다. Ascites form of Ehrlich carcinoma에 대한 抗腫瘍效果 實驗에서 扶正抗癌湯抽出液과 MMC를 병용투여한 결과, 扶正抗癌湯抽出液에 의하여 MMC의 抗腫瘍效果가 增加하였다. Solid form of Ehrlich carcinoma에 대한 抗腫瘍效果 實驗에서 扶正抗癌湯抽出液과 MMC를 병용 투여하였을 경우, MMC를 단독 투여하였을 경우보다 腫瘍의 크기가 현저하게 減少하는 결과를 보였다. Ehrlich ascites carcinoma cell에 扶正抗癌湯抽出液과 MMC를 병용 투여하였을 경우, MMC를 단독 투여하였을 경우보다 lysosomal enzymes의 活性이 强하게 나타났다. 本 實驗을 통하여 扶正抗癌湯抽出液은 MMC의 抗腫瘍效果를 증가시키는 效果를 보였다. 또한 扶正抗癌湯抽出液은 마우스에서 solid form of Ehrlich ascites carcinoma의 크기를 감소시키는 效果를 나타냈으며, 생존기간 實驗에서는 扶正抗癌湯抽出液과 MMC를 병용투여시 ascites tumor에 MMC를 단독으로 투여하였을 때와 비교하여 유의하게 생존기간을 증가시키는 결과를 보였다. 이상의 결과를 종합하여 볼 때 扶正抗癌湯抽出液은 用量에 依存的으로 直接的인 抗腫瘍效果가 있으며, 抗癌療法劑인 MMC의 效果를 亢進시키는 것으로 보아 間接的인 抗腫瘍效果도 있을 것으로 思科되나 正確한 效果를 究明하기 위해서는 보다 正確한 抗腫瘍機轉에 대한 硏究와 藥物學的 硏究 및 臨床的 硏究가 追加되어야 할 것이다. In order to investigate the effects of Bujeonghangamtang Extract(扶正抗癌湯抽出液) on antitumor effects after human cell lines(A549, Hep3B, Caki-1, Ehrlich) transplantation into the peritoneal cavity or right groin in mice induced by RPMI 1640 and DMEM etc, the extracts of its herbal medicines were orally administered for 10 or 12 days. Experimental studies were performed for measurement of antitumor effect of Mitomycin C(MMC) and lysosomal enzyme's activities using colony forming efficiency, SRB assay which were regarded as a valuable method for the measurement of antitumor effects of unknown compound on tumor cell lines. The results obtained in this studies were as follows: 1. The change of colony-forming efficiency and SRB assay of Caki-1 cells, Hep3B and A549 Cells after exposure to the extract of Bujeonghangamtang extract depressed the growth of tumor cells by concentration of Bujeonghangamtang. 2. Antitumor activity of the ethanol extract of Bujeonghangamtang extract and MMC on ascites form of Ehrlich carcinoma in mice is slightly improved. Especially the mean of survival times in the group of 200㎎/㎏ and MMC 0.1㎎/㎏ is improved over 30.9%. 3. When Bujeonghangamtang extract and MMC are administered together, the weight of tumor is more decreased than MMC alone. 4. The lysosomal enzyme's activities of the Bujeonghangamtang extract and MMC are more significantly improved than MMC alone. According to the above result, it could be suggested that Bujeonghangamtang extract has indirect antitumor effect by the increase of MMC uptake.

원발성 위 소세포암 1례

윤상애,전혜정,함희원,박형석 건국대학교 의과학연구소 1995 건국의과학학술지 Vol.5 No.-

Small cell carcinoma originates from APUD cell of any part of the body. Usually the cases are discovered in the lung, and have poor prognosis. Primary small cell carcinoma of the stomach has been recognized recently, and only three cases have been reported in the Korea. This tumor is morphologically analogous to small cell carcinoma of the lung, and characterized by very aggressive clinical course. We report a case of primary small cell carcinoma of the stomach which had hepatic metastasis. The lesion of the stomach, located in the upper body and cardia, is ulcerated with irregular margin and dirty surface covered with exudates.

Analysis of Clinical Research Trends for Acupotomy Treatment of Peripheral Facial Palsy

Jeon, Seok Hee,Choi, Ji Min,Yoo, Jae Hee,Shin, Jeong Cheol Korean AcupunctureMoxibustion Medicine Society 2021 대한침구의학회지 Vol.38 No.4

The purpose of this review was to investigate acupotomy treatment for peripheral facial palsy. By reviewing recent clinical trends, this may contribute to standardizing acupotomy treatment methods. There were 7 randomized controlled trials and 6 case series using acupotomy treatment for peripheral facial palsy published between January 01, 2014 and April 05, 2021, which were retrieved from 9 online databases. The number and characteristics of participants, main treatment sites, combination treatments, size of acupotomy needle, frequency and total period of treatment, evaluation indices, efficacy, and adverse events were analyzed. "Tender point or induration," "infraorbical foramen," and "buccal mucosa" were the most used treatment sites. The sizes of acupotomy needles varied from 20 mm to 80 mm in length, and 0.35 mm to 1.0 mm in diameter. One treatment cycle was performed every 3 to 5-7 days, and the number of treatments per treatment session ranged from 3 to 5-9 cycles. The results were evaluated using 1 to 4 evaluation indices and 9 different evaluation indices were used overall. The efficacy rate was the most used index, followed by the House-Brackmann grade, and electrocardiography. The "Risk of Bias 2," categorized most studies as having "some concerns." There were few adverse events reported.

Efficacy of tenofovir-based rescue therapy for chronic hepatitis B patients with resistance to lamivudine and entecavir

( Hee-jeong Jeon ),( Seok Won Jung ),( Neung Hwa Park ),( Yujin Yang ),( Jin-hee Noh ),( Jae-sung Ahn ),( Hyung Rae Kim ),( Jae Ho Lee ),( Jung Woo Shin ) 대한간학회 2017 Clinical and Molecular Hepatology(대한간학회지) Vol.23 No.3

Background/Aims: Tenofovir disoproxil fumarate (TDF) monotherapy for 48 weeks provided a virological response comparable to that of TDF and entecavir (ETV) combination therapy in patients infected with ETV-resistant hepatitis B virus (HBV). Little long-term data in routine clinical practice are available regarding the optimal treatment of patients with ETV-resistant HBV. Methods: We investigated the long-term antiviral efficacy of combination therapy of TDF+lamivudine (LAM) or TDF+ETV compared to that of TDF monotherapy in 73 patients with resistance to both LAM and ETV. Results: Patients were treated with TDF monotherapy (n=12), TDF+LAM (n=19), or TDF+ETV (n=42) for more than 6 months. The median duration of TDF-based rescue therapy was 37 months. Virologic response (VR) was found in 63 patients (86.3%). The rates of VR among the three groups (TDF monotherapy, TDF+LAM, and TDF+ETV) were not statistically different (log-rank P=0.200) at 12 months (59.3%, 78.9%, and 51.8%, respectively) or at 24 months (88.4%, 94.7%, and 84.2%). In addition, treatment efficacy of TDF-based combination or TDF monotherapy was not statistically different with ETV-resistant strains or exposure to other antiviral agents. In multivariate analysis, only lower baseline HBV DNA level was an independent predictor for VR (hazard ratio, 0.723; 95% confidence interval, 0.627-0.834; P<0.001). Conclusions: TDF monotherapy was as effective as combination therapy of TDF+LAM or TDF+ETV in maintaining long-term viral suppression in chronic hepatitis B patients with resistance to both LAM and ETV. HBV DNA level at the start of TDF rescue therapy was the only independent predictor of subsequent VR. (Clin Mol Hepatol 2017;23:230-238)

Reliability during Thermal Shock Testing of NiCr Films on Mn-Ni-Co Oxide Substrates

Jeon, Min Seok,Song, Jun Kwang,Lee, Eui Jong,Lee, Hee Soo,No, Tae Hyung,Kim, Duck Hee,Park, In Gil Trans Tech Publications, Ltd. 2006 Key Engineering Materials Vol.317 No.-

<P>There is an increasing reliability concern of thermal stress-induced failures in multilevel coatings in recent years. This work reports investigations of cracking of NiCr coatings due to thermal cycling. The temperature cycling in accelerated testing was performed in three temperature range of 150, 175 and 200°C. The NiCr coatings were considered to have failed when the sheet resistance changed by 30% relative to an initial value. As the cyclic repetition of thermal shock increased, the sheet resistance of NiCr coatings increased. The Coffin-Manson equation was applied to the failure mechanism of cracking of NiCr coatings and the SEM observation of cracks and delamination in NiCr coatings due to thermal cycling agreed well with the failure mechanism.</P>

QPSK Modulation Based Optical Image Cryptosystem Using Phase-shifting Digital Holography

Seok Hee Jeon,길상근 한국광학회 2010 Current Optics and Photonics Vol.14 No.2

We propose a new technique for the optical encryption of gray-level optical images digitized into 8-bits binary data by ASCII encoding followed by QPSK modulation. We made an encrypted digital hologram with a security key by using 2-step phase-shifting digital holography, and the encrypted digital hologram is recorded on a CCD camera with 256 gray-level quantized intensities. With these encrypted digital holograms, the phase values are reconstructed by the same security key and are decrypted into the original gray-level optical image by demodulation and decoding. Simulation results show that the proposed method can be used for cryptosystems and security systems.
