Purpose: Proliferation marker Ki-67 is widely used in cancer prognosis prediction. We tried to investigate the role of Ki-67 as a prognostic factor in stomach cancer after surgery in this study. Methods: We retrospectively evaluated 251 patients who underwent curative resection for gastric cancer from 2010 to 2015. In pathologic examination, Ki-67 labeling index was defined as the percentage of Ki-67 antigen positive cells. Prognostic significance of Ki-67 for gastric cancer was evaluated. Disease-free survival (DFS) was assessed as a primary end-point. Results: The median follow-up period was 28.0 months. Thirty-one patients (12.4%) showed Ki-67 labeling index (LI) lower than 25%. Sixty-eight patients (26.6%) showed recurrence during follow-up period. Recurrence was associated with Ki- 67 LI level (≤25%, P = 0.016), and lymph node metastasis status (P = 0.002). High Ki-67 LI level (>25%) was also related to p53 positivity (P < 0.001) and poorly cohesive type (P = 0.002). The 3-year DFS was 69.4%. Low Ki-67 LI level (≤25%) was related with low DFS (47.6% vs. 72.6%, P = 0.016). T stage (P < 0.001), N stage (P = 0.006), lymphovascular invasion (P = 0.010), and neuronal invasion (P = 0.001) also affected the DFS. In addition, T stage (P = 0.03) and Ki-67 LI (P = 0.035) were independent prognostic factors for DFS. In patients treated with adjuvant chemotherapy (n = 239, 93.4%), low Ki-67 (≤25%) was a poor prognostic factor for DFS (P = 0.013). Conclusion: Low Ki-67 LI predicts high rate of progression and low DFS of stomach cancer. Ki-67 LI can be a predictive marker in resected stomach cancer treated with surgery and adjuvant chemotherapy.

개구리 皮膚의 伸張度와 X線 全身照射가 이에 미치는 影響

李基錫,朱永恩 慶北大學校 醫科大學 1975 慶北醫大誌 Vol.16 No.1

개구리皮膚의 伸張度와 X-線照射가 이에 미치는 影響을 알기 爲하여 腹部 및 背部皮膚에서 各各 矢狀 및 橫斷切片을 作成하여 길이-張力曲線中 彈性의 限界內에서 Hooke의 法則에 따르는 部位에서 Young率을 求 하고 1,000R의 X-線全身照射를 한 後 1,3,5,7 및 10日에서 各各 皮膚切片의 伸張度를 求하여 서로 比較 하였던 바 다음과 같은 結果를 얻었다. 1. 正常개구리의 腹部皮膚의 矢狀 및 橫斷切片의 Young率은 各各 4.09×10 exp (7) dyne/㎠ 및 3.99×10 exp (7) dyne/㎠이었다. 背部皮膚에서 얻은 矢狀 및 橫斷切片의 Young率은 各各 3.69×10 exp (7) dyne/㎠ 및 5.81×10 exp (7) dyne/㎠이었다. 2. X-線 全身照射를 한 群에서 腹部皮膚에서는 그 矢狀切片의 Young率은 照射 3日에서 5.38×10 exp (7) dyne/㎠으로서 가장 높고 그 後는 漸次 낮아지는 傾向을 나타내었고 照射 10日에서는 4.20×10 exp (7) dyne/㎠으로서 正常値에 가까워지는 傾向을 나타내었다. 橫斷切片에서는 照射 3日 및 5日에서 Young率이 各各 4.55×10 exp (7) dyne/㎠ 및 4.50×10 exp (7) dyne/㎠으로서 가장 높고 그後는 第10日까지 次次 낮아진듯하나 그 傾向이 矢狀切片에서 처럼 뚜렷하지 않았다. 3. X-線 全身照射로서 背部皮膚에서는 그 矢狀切片의 Young率은 照射 第3日 및 5日에서 各各 4.25×10 exp (7) dyne/㎠ 및 4.30×10 exp (7) dyne/㎠으로서 높아지는 傾向을 나타내고 그後는 漸次 낮아져서 第10日에서는 正常値와 비슷하게 되는 傾向을 나타내었다. 橫斷切片에서의 Young率도 照射後 第3日 및 5日에서 各各 6.02×10 exp (7) dyne/㎠및 6.00×10 exp (7) dyne/㎠으로서 正常値보다 若干 높은듯 하고 그後는 낮아지는 傾向을 보이나 그 程度가 矢狀切片에서 처 럼 뚜렷하지 못하였다. In an attempt to observe the changes of the distensibility of the frog skin by whole body X-irradiation, the sagittal and transverse strips were excised from the abdominal and back skin of the frog (Rana nigromaculata) following whole body X-irradiation with 1,000R. Young Modulus of the strip was calculated from the length-tension curve of each sample, and a comparison was made with the non-irradiated control group. Experiments were performed on 1,3,5,7 and 10 days after the irradiation, and the results thus obtained are summarized as follows: 1. Young Modulus of the sagittal and transverse strips of the abdominal skin of the normal frog was 4.09×10 exp (7) dyne/㎠ and 3.99×10 exp (7) dyne/㎠, respectively. Young Modulus of the back skin of the normal frog was 3.69×10 exp (7) dyne/㎠ in the sagittal strip, and 5.81×10 exp (7) dyne/㎠ in the transverse strip. 2. Young Modulus of the sagittal strip of the abdominal skin in the irradiated group was the highest (5.38×10 exp (7) dyne/㎠) on the 3rd post-irradiation day, and a tendency of gradual decrease to the normal value on the 10th post-irradiation day was observed. In the transverse strip of the abdominal skin in the irradiated group, the highest values of Young Modulus were observed on the 3rd(4.55×10 exp (7) dyne/㎠) and 5th(4.50×10 exp (7) dyne/㎠) post-irradiation day, and a tendency of gradual decrease till 10th day was observed, but the tendency was not as prominent as in the sagittal strip. 3. A tendency of the elevated values of Young Modulus on the 3rd(4.25×10 exp (7) dyne/㎠) and 5th(4.30×10 exp (7) dyne/㎠) post-irradiation day with the decreasing values to the normal value on the 10th day was observed in the sagittal strip of the back skin of the irradiated frog. In the transverse strip of the irradiated frog, Young Modulus showed a slight increase on the 3rd(6.02×10 exp (7) dyne/㎠) and 5th(6.00×10 exp (7) dyne/㎠) day after the irradiation, but a tendency of decrease was observed thereafter.

Background/Aims: Hepatolithiasis or primary intrahepatic stones may be accompanied later by intrahepatic cholangiocarcinoma. This cancerous lesion is frequently associated with atypical hyperplastic epithelium that was suspected of being precancerous. To investigate the Ki-ras or p53 mutation may play a role in carcinogenesis, and to determine whether atypical hyperplastic epithelium may be precancerous, this study was performed in intrahepatic cholangiocarcinomas associated with hepatolithiasis. Methods: We examined 12 patients with intrahepatic cholangiocarcinomas associated with hepatolithiasis. Ki-ras point mutations were assessed by direct DNA sequencing. Expressions of p53 protein were immunohistochemically assessed. The overexpression of p53 and point mutation of Ki-ras were examined in normal, hyperplastic, atypical hyperplastic, and can- cerous tissues separately. Results: The expressions of p53 protein were detected in 4 (33%) of 12 cholangiocarcinomas and Ki-ras point mutations at codon 12 were found in 2 (17%) of 12 cholangiocarcinomas. In those two carcinoma cases which contained the mutant sequence of Ki-ras, the same point mutation from wild type GGT (glycine) to GAT (aspartic acid) was. found in the associated atypical hyperplastic epithelium. However, none of the normal and hyperplastic epithelium harbored Ki-ras or p53 mutations. Conclusions: The overexpression of p53 may play a part in the carcinogenesis of some intrahepatic cholangiocarcinomas associated with hepatolithiasis, whereas the role of Ki-ras mutations in those cases is dubious. However, Ki-ras point mutation at codon 12 may be responsible for either cancer or atypical hyperplastic epithelium associated with hepatolithiasis in certain cases, suggesting atypical hyperplastic epithelium may give rise to carcinoma.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

<P> e15686 </P><P> Background: Herein, we investigated the impact of pathologic differentiation (well or poorly differentiated) in metastatic grade 3 GEP-NEC patients receiving etoposide and platinum-based therapy. Simultaneously, we evaluated a more exact Ki67 index cut-off point to select patients with grade 3 GEP-NEC who might benefit from etoposide plus platinum (EP)-based therapy. Methods: Among patients pathologically diagnosed with metastatic grade 3 GEP-NECs at Samsung Medical Center between June 2013 and March 2016, 31 GEP-NEC patients receiving etoposide and platinum-based therapy were included in this study. Results: Primary sites included 13 foregut-derived GEP-NECs [stomach (n = 4), duodenum (n = 4), and pancreas (n = 5)] and 2 hindgut-derived GEP-NECs of the rectum. Sixteen unclassified GEP-NECs originated from 7 gall-bladder (GB), 6 liver and 3 unknown primary sites. According to pathologic differentiation, 14 patients had well differentiated and 17 had poorly differentiated grade 3 GEP-NECs. Between well differentiated and poorly differentiated grade 3 GEP-NECs, there was a significant difference in the distribution of Ki67 index. There was no significant difference of treatment efficacy between well and poorly differentiated grade 3 GEP-NECs (RR; 35.7% vs. 41.2%, p = 0.525). Tumor response to EP occurred in 5 of 7 patients with Ki67 > 60% and 7 of 24 with Ki67≤60%, which was significantly different (RR; 71.4% vs. 29.2%, P = 0.043). There was no significant difference in PFS according to pathologic differentiation (well differentiated vs. poorly differentiated) and Ki67 index ( > 60% vs ≤60%). Conclusions: Grade 3 GEP-NECs could be morphologically classified into well and poorly differentiated NETs. Additionally, among grade 3 GEP-NECs, there was a significant difference in ranges of Ki67 index between well and poorly differentiated NECs. Higher levels ( > 60%) of Ki67 index might be a predictive marker for efficacy of EP as a standard regimen in grade 3 GEP-NECs. </P>

Comparison of trophic factors changes in the hippocampal CA1 region between the young and adult gerbil induced by transient cerebral ischemia.

Yan, Bing Chun,Park, Joon Ha,Kim, Sung Koo,Choi, Jung Hoon,Lee, Choong Hyun,Yoo, Ki-Yeon,Kwon, Young-Geun,Kim, Young-Myeong,Kim, Jong-Dai,Won, Moo-Ho Kluwer Academic/Plenum Publishers 2012 Cellular and molecular neurobiology Vol.32 No.8

<P>In the present study, we investigated neuronal death/damage in the gerbil hippocampal CA1 region (CA1) and compared changes in some trophic factors, such as brain-derived neurotrophic factor (BDNF), glial cell line-derived neurotrophic factor (GDNF) and vascular endothelial growth factor (VEGF), in the CA1 between the adult and young gerbils after 5 min of transient cerebral ischemia. Most of pyramidal neurons (89%) were damaged 4 days after ischemia-reperfusion (I-R) in the adult; however, in the young, about 59% of pyramidal neurons were damaged 7 days after I-R. The immunoreactivity and levels of BDNF and VEGF, not GDNF, in the CA1 of the normal young were lower than those in the normal adult. Four days after I-R in the adult group, the immunoreactivity and levels of BDNF and VEGF were distinctively decreased, and the immunoreactivity and level of GDNF were increased. However, in the young group, all of their immunoreactivities and levels were much higher than those in the normal young group. From 7 days after I-R, all the immunoreactivities and levels were apparently decreased compared to those of the normal adult and young. In brief, we confirmed our recent finding: more delayed and less neuronal death occurred in the young following I-R, and we newly found that the immunoreactivities of trophic factors, such as BDNF, GDNF, and VEGF, in the stratum pyramidale of the CA1 in the young gerbil were much higher than those in the adult gerbil 4 days after transient cerebral ischemia.</P>

위암 환자에서 세포성 면역 기능에 관한 연구

We performed a variety of lymphocyte stimulation tests, delayed hypersensitivity skin tests, and enumeration of several lymphocyte subpopulations in 21 patients with gastric cancer who did not receive any form of anticancer therapy, and in 20 healthy controls. The gastric cancer patients had significantly decreased number and total score of positive reactions in delayed hypersensitivity skin tests compared with the healthy controls. The percent of CD_(4) positive lymphocytes in the gastric cancer patients was significantly decreased compared to the normal control subjects, but it had no correlation with the total score of delayed cutaneous hypersensitivity reactions. The ratio of helper to suppressor cells was lower in the cancer group. The uptake of 3H-thymidine was markedly depressed in cancer patients when stimulated with various mitogens. There was little correlation between any of the stimulation tests and any of the lymphocyte subpopulation proportions to delayed hypersensitivity cutaneous reactions. Optimal proliferative response was found in lymphocytes stimulated with 10 micrograms of concanavalin-A and 10 microgram of phytohemagglutinin. Advanced stage patients had greatly depressed delayed hypersensitivity skin reactions and proliferative responses to mitogens compared with localized diseases. These results suggest that gastric cancer patients have depressed cellular immune functions, which mainly result from the decreased helper cells and defects in functional proliferative response to mitogens. Interleukin-2 and interferon-gamma restored the in vitro proliferative response of lymphocyte in patients with gastric cancer.

Gilbert 증후군에서 열량 제한 시험과 Phenobarbital 자극 시험의 의의(14예)

이헌영,채경훈,정재훈,강윤세,김연수,문희석,박기오,이엄석,김선문,김석현,성재규,이병석,이강욱 충남대학교 의학연구소 2003 충남의대잡지 Vol.30 No.2

Gilbert 증후군은 인구의 7%에서까지 나타날 수 있는 매우 흔한 증후군으로서 비진행성인 양성의 만성적 경과를 치하며, 간질환의 증상과 징후가 없는 경한 비포합형 고빌리루빈혈증이 특징인 일종의 체질적인 증상으로서 혈장 빌리루빈 농도에 대한 사춘기의 영향 때문에 10대와 20대에 자주 진단이 된다. 따라서 임상적인 중요성은 미약하지만 높은 빈도가 예상되는 점에 그 중요성이 부여되어야 할 것이다. 따라서 적정한 임상적 진단법으로 기왕에 소개된 열량제한 시험과 phenobarbital 유도 시험을 시행하고 이들의 진단적 가치를 알아보기 위하여 본 연구를 시행하였다. 1990년 7월부터 1999년 4월까지 충남대학교병원에 내원하여 HBsAg, IgG anti-HBc 및 anti-HCV가 음성이고, 간 초음파 스캔에서 이상이 없으며, 혈청 AST, ALT 및 AP가 정상인 비음주자에서 경한 비포합형 고빌리루빈혈증이 있는 14예의 환자들을 대상으로 ^(99m)Tc-DISID 스캔을 시행하였으며, 기저 치 총빌리루빈 및 포합형 빌리루빈 치를 측정한 다음에 하루에 400Kcal로 48시간동안 제한한 열량 제한 시험을 시행하였고, phenobarbital을 하루 60mg씩 5일간 투여한 후에도 각각 총빌리루빈과 포합형 빌리루빈 치를 검사하여 비포합형을 구하였다. 대상 환자들은 모두 14예로서 남자가 11예(78.6%)였고 여자가 3예(21.4%)여서 3.7:1로 남자에서 많았으며, 20대가 6예(42.9%), 30대가 역시 6예(42.9%) 및 40대가 2예(14.2%)로서 2,30대가 대부분(85.8%)이었다. 열량 제한 시험 후의 총빌리루빈 치, 비포합형 및 포합형 빌리루빈 치들은 평균 각각 5.5±2.7, 4.2±2.3 및 1.3±10mg/dL 로서, 시험 전 치들인 3.0±0.8, 2.2±0.8 및 0.7±0.4mg/dL 보다 유의하게(p=0.001, p=0.001, p=0.023) 상승하였다. 포합형 빌리루빈 치도 유의하게 상승하였으나 비포합형의 상승보다는 훨씬 낮아서 주로 비포합형이 증가하였다. phenobarbital 투여 중 설사가 발생하여 중단한 1예를 제외한 13예에서 열량 제한 시험 후에 상승하였던 총, 비포합형 및 포합형 빌리루빈 치가 phenobarbital 유도 시험후에는 2.0±1.1, 1.5±0.8 및 0.5±0.4mg/dL로서 열량 제한 시험 결과보다 유의하게 낮아졌고(p=0.00, p=0.000, p=0.001), 열량 제한 시험 전의 기초치들인 3.0±0.8, 2.2±0.8 및 0.7±0.4mg.dL 보다도 더욱 낮아졌으며 유의한 차이(p=0.001, p=0.02, p=0.005)를 나타내었다. 14예에서 시행한 ^(99m)-Tc DISIDA 스캔에서 9예(64.3%)가 정상이었고, 5예(35.7%)에서는 심장 및 신장으로의 간외 섭취가 3예였고, 60분까지 소장 배출이 없는 배설 지연 예와 담낭 수축 불량 예가 각각 1예 씩 발견되었다. Phenobarbital 투여시험에서 민감도가 열량제한시험에 비해 더 높았다(92.3%와 50.0%). Gilbert 증후군에서 1일 400 Kcal로 48시간의 열량제한 시험과 1일 60mg의 phenobarbital을 5일간 투여하는 유도 시험은 편리하고 유용한 임상적인 진단법으로 이용할 수 있다고 생각된다. 그러나 열량 제한 시험에서는 증가 기준의 통일이 필요하다고 유추되며 phenobarbital 유도 시험이 민감도가 더 높은 것으로 생각된다. Gilbert's syndrome is very frequent and benign chronic process characterized by mild, intermittent, unconjugated hyperbilirubinemia without any symptom and sign of liver disease. Previously intoduced caloric restriction test and phenobarbital stimulation test as two appropriate clinical tests had been examined and their diagnostic values were reevaluated. Fourteen patients with mild, persistent, unconjugated hyperbilirubinemia were included. Subsequently caloric restriction has been applicated by 400 Kcal/day for 48 hours and phenobarbital has been prescribed by 60 mg/day for 5 days. Therafter serum levels of total and direct bilirubin were measured. Most of the patients were third and fourth decade(85.8%) and male predominant. Each basal serum levels of total, indirect and direct bilirubin were 3.0±0.8, 2.2±0.8 and 0.7±0.4 mg/dL. After caloric restriction test, each levels were increased significantly to 5.5±2.7, 4.2±2.3 and 1.3±1.0 mg/dL(p=0.001, p=0.001, p=0.023). After phenobarbital stimulation test for 13 patients had been practiced, increased levels of each bilirubin after caloric restriction test were decreased significantly to 2.0±1.0, 1.5±0.8 and 0.5±0.4 mg/dL(p=0.000, p=0.000, p=0.001) and these levels were significantly lower than basal levels(p=0.001, p=0.02, p=0.005). The sensitivities of caloric restriction test were 85.7%, 50.0%, and 71.4%, 35.7%(1.0, 1.5 mg increase of total bilirubin and 1.0, 1.5 mg/dL increase of indirect bilirubin). The sensitivities of phenobarbital stimulation test were 93.2% and 92.3% at criteria of 1.5 mg/dL increase of total bilirubin and indirect bilirubin. On the diagnosis of Gilbert syndrome, caloric restriction test and phenobarbital stimulation test are convenient and useful diagnostic tools in clinical face. And also phenobarbital stimulation test has higher sensitivity than caloric restriction test. Furthermore, standardization of bilirubin increment would be necessary in caloric restriction test.

The survey study was conducted to investigate the rice cake consumption pattern including the frequency of intake and the degree of preference and the area of improvement for Korean rice cake among college students. About the motive for purchases of rice cake, 'taste is good(43.3%)' was the highest, and 'eat as a snack' the next (42.9%). The reason which does not eat the rice cake frequently was uncomfortable to eat (24.1%), insipid(21.4%), not variously assorted(17.9%) in the order named. The college students surveyed were eating rice cake as a snack mainly. They wanted the rice cake to be charmed and be in pretty shape, and fusion style for gift. And they wanted to be rice cake more sweetened and cool taste like ice cream. Therefore, traditional rice cake is required for further research for the development of product which is more acceptable for the young adults.

Korean Dictionaries and Some Model Dictionaries of the World : Critical Essays toward the Plan for a New Korean Dictionary

Lee, Sang Sup,Nam, Ki Shim,Ahn, Sam Huan,Choi, Young Ai,Hong, Chai Song 연세대학교 언어정보개발원 1988 사전편찬학 연구 Vol.1 No.1

After briefly reviewing the history of lexcoigraphy in modem Korea, Nam Kishim tackles many problems created by the general deficiency of current Korean monolingual dictionaries in phonological morphological and semantic points. For example, most Korean dictionaries do not treat such phonological changes as the shortening of the stem vowel ㅓ in 더운, the prenominal form of the adjective 덥다, whose stem vowel ㅓ is pronounced long. He also takes issue with the practice of Korean dictionaries of including all kinds of proper names on little reliable principles : a typical dictionary enters a 600m-high hill while excluding better-known mountains higher than that. Hong Chai-song concentrates on the often misguiding information on transitive / intransitive verbs in current dictionaries. For example, a representative dictionary designates the verb 뛰다 simply as intransitive. But it is quite often used as an transitive also. In the sentence, 철수는 운동장을 뛰었다, 운동장 is the object of the transitive verb 뛰다. How could the compilers miss such an obvious fact? Hong suggests that they may have not been interested in being grammatically informative. A historical survey of the Oxford English Dictionary(OED) is given by Lee Sang-sup, with special emphasis on the vast amount of quotations from real sources contributed by thousands of volunteer readers through several decades and on its unwavering historical principle. A comparison between the OED's definition of Kimchi and a Korean dictionary's 김치 is given, showing the difference of principle in treating the same lexical item. Ahn Sam-huan presents a detailed account of Grimm's Deutsches Wo¨rterbuch which took generations of German lexicographers 133 years from its inception to its completion in 1971. On the basis of his study, Ahn suggests that future dictionary makers should cooperate as a group on a long-range comprehensive project. A moltivolume dictionary is an all-important cultural event for the whole nation, not to be influenced by private commercial interests.
