N/A Comparative analytic review on clinical, endoscopic and histopathological findings was done in 13 cases of young age (under 29), 446 cases of mid age (30~69) and 39 cases of old age (above 70) stomach cancer who were visited Department of Internal Medicine of Masan Koryo General Hospital from March 1981 to July 1985. The following results were obtained: The peak of age incidence was the 5th decade amounting to 36.8%. The ratio between male and female was 2.6:1. The main chief complaint of each group was epigastric pain and it was followed by epigastric fullness. The most patient had the duration of symptom from 3 months to 6 months. For old-age group, mid-age group, major site of lesion in the antrum, meanwhile body for young-age group. The most frequent type of gastric cancer was type III in each group by Borrmanns classification. For each group, adenocarcinoma was major cases in the view of histopathological findings, and incidence of well differentiated type adenocarcinoma were lower in young-age group than others.

Background/Aims: Comparative occurrence of ischemic stroke for rhythm versus rate control strategy in patients with non-valvular atrial fibrillation (NVAF) is still inconclusive. The purpose of this study was to investigate whether the rhythm control strategy is associated with a lower risk of ischemic stroke compared to the rate control strategy in NVAF patients. Methods: The CODE-AF registry prospectively enrolled 6,280 consecutive patients who were treated for NVAF at 10 tertiary referral centers in South Korea. Of these, 2,513 NVAF patients (age, 67 ± 10 years; male, 61.8%) were clinically followed up for over 1-year and divided into rate and rhythm control groups. Results: Those treated with the rhythm control strategy were younger and had less proportions of underlying disease compared to those treated with the rate control strategy. After the propensity matching analysis, those treated with the rhythm control strategy had similar baseline characteristics including the CHA<sub>2</sub>DS<sub>2</sub>-VASC score compared to those treated with the rate control strategy. The rate of oral anticoagulation, all bleeding, and hospitalization were also similarly between the two groups. The incidence rate of ischemic stroke in the rhythm control group was significantly lower than in the rate control group (0.7 vs. 6.9 per 1,000 person-years, p = 0.011). Conclusions: The rhythm control strategy demonstrated a beneficial effect to lower the risk of ischemic stroke during a 1-year follow-up compared to the rate control strategy.

Jae-Young Cha1,,Jin-Chul Park,Beong-Sam Jeon,Young-Choon Lee,Young-Su Cho 한국미생물학회 2004 The journal of microbiology Vol.42 No.1
The influence of feedstock amino acids, salt, carbon and nitrogen sources on glutathione production by Saccharomyces cerevisiae FF-8 was investigated. Glucose, yeast extract, KH2PO4, and L-cysteine were found to be suitable feedstock. Highest glutathione production was obtained after cultivation with shaking for 72 h in a medium containing glucose 3.0% (w/v), yeast extract 3.0%, KH2PO4 0.06% and L-cysteine 0.06%. The glutathione concentration achieved using this medium increased 2.27-fold to 204 mg/l compared to YM basal medium.

Background/Aims: Little is known about the national colonoscopy volume in Asian countries. This study aimed to assess the national colonoscopy volume in Korea over a 12-year period on the basis of a nationwide population-based database. Methods: We conducted a population-based study for colonoscopy claims (14,511,158 colonoscopies performed on 13,219,781 patients) on the basis of the Korean National Health Insurance Service database from 2002 to 2013. The 12-year national colonoscopy burden was analyzed according to patient age, patient sex, and healthcare facility type. Results: The overall volume of colonoscopy increased 8-fold over the 12-year period. The annual colonoscopic polypectomy rate significantly increased in all patient sex and age groups over the 12-years period (all p<0.001). The yearly colonoscopic polypectomy rate for men was significantly increased compared with that for women (2.3% vs 1.7%, p<0.001) and for the screening-age group compared with that for the young-age group (2.0% vs 1.6%, p<0.001). The yearly colonoscopic polypectomy rate relative to the total colonoscopy volume significantly increased in primary, secondary, and tertiary facilities by 2.4%, 1.9%, and 1.4% during the 12-year period (all p<0.001). In addition, the annual colonoscopy volume covered by high-volume facilities significantly increased by 1.8% in primary healthcare facilities over the 12-year period (p<0.001). Conclusions: Healthcare resources should be prioritized to allow adequate colonoscopic capacity, especially for men, individuals in the screening-age group, and at primary healthcare facilities. Cost-effective strategies to improve the quality of colonoscopy may focus on primary healthcare facilities and high-volume facilities in Korea.

This study examined the influence of various factors of RFID use in mobile RFID environment, focusing on pharmacies` RFID systems. The purpose of the study was to verify the possibility of a more widespread use of RFID and mobile RFID in medical industry by exploring what impact RIFD use factors have on the intention to use in RFID environment. The subjects were pharmacists who have their own pharmacies in Seoul and Gyeonggi Province. Of 400 questionnaires distributed to the respondents, 392 were used in the final analysis except 8 with insufficient answers. The empirical analysis results showed that perceived security, perceived cost, and social influence had significant impacts on trust, while social influence and perceived cost had significant impacts on perceived risk. Among RFID use factors, social influence, perceived security, and perceived risk had significant impacts on intention to use in mobile RFID environment. Trust and perceived cost did not have a significant impact. The summary of analysis results, implications, and limitations are presented in the conclusion.

N/A Objectives: Mutations in the glucokinase (GCK) gene are considered a possible cause of maturity-onset diabetes of the young. The purpose of this study was to evaluate the contribution of this gene to the development of non insulin dependent diabetes mellitus (NIDDM), gestational diabetes mellitus (GDM) and post-renal transplantation diabetes mellitus (PTDM). Method: Identification of GCK mutation was attempted on 39 NIDDM patients, 2 GDM patients and 58 selected renal allograft recipients with PTDM and 45 normal controls. The exons in the GCK gene were examined by polymerase chain reaction (PCR), followed by analysis of single-stranded DNA conformational polymorphism (SSCP). The abnormal bands were also confirmed by DNA sequencing analysis. The exons of affected family members were also investigated for mutations of the GCK gene. Results: Two of the 58 PTDM patients (3.4%) were found to have CKK mutations. One had the mutation on exon 5 and the other on intron 7. One control subject had the mutation on intmn 9. The mutation of exon 5 was identified as a substitution of CCT (proline) for CTT (leucine) at codon 164, which has not ever reported before. The family members of the PFDM patient with mutation of exon 5 were analyzed by PCR followed by SSCP, and two of them revealed the same mutation. The abnormal band on the SSCP analysis of exon 7 was identified as the insertion of base C/T at the 39th nucleotide in intron 7. Two family members of this patients also had same band on SSCP. The one mutation of 45 normal controls was CT located at the 8th nucleotide in intron 9, which was a common polymorphism. Conclusion: We found GCK mutations in subjects with PTDM and we speculate that these mutations may be one of the contributing cause of PTDM.

차량 전면충돌시 에너지흡수량이 가장 큰 차량전면부 사이드부재의 기본형상인 점용접된 단일모자형 단면부재에 대하여, 정적(0.00017m/sec), 준정적(0.017m/sec) 축방향 압궤실험을 행하였다. 이를 기초로 자체 제작한 수직식 공기압 충격실험장치를 이용하여 실제 차량이 충돌하는 것을 상정하여 충격속도 7.19m/sec(충격에너지 1034J)하에서 형상의 변화 및 폭비와 플랜지 용접간격의 변화에 따른 압궤특성을 고찰하여, 최적의 에너지 흡수성능을 갖는 구조부재에 대하여 검토하였다. The fundamentally and widely used spot welded sections of automobiles(hat and double hat shaped section members) absorb most of the energy in a front-end collision. The sections were tested on axial static(0.00017m/sec) and -quasi-staic(0.017m/sec) loads. Based on these test results, spcimens with various thicknesses, width ratios and spot weld pitches on the flange have been tested with high impact velocity(7.19m/sec 1034J) which imitate a real life car arash Characteristics of collapse have been reviewed and structures of optimal energy absorbing capacity is suggested.
