The objective of this study was to evaluate the efficacy and the pattern of regimens prescribed for the treatment of peptic ulcer disease in a regional community hospital. 226 patients were treated as an outpatient and followed for one year. 88 patients $(38.9\%)$ had gastric ulcer (GU) alone, 6 patients $(2.7\%)$ had duodenal ulcer (DV) alone, 5 patients $(2.2\%)$ had gastroesophageal reflux disease (GERD) alone, 25 patients $(11.1\%)$ had both GU and DU, 88 patients $(38.9\%)$ had both GU and GERD, and 14 patients $(6.2\%)$ had both DU and GERD. During this study period no one was treated for Zollinger-Ellison Syndrome. The disease showed higher occurrence in male population (139 patients, $61.5\%$) and among the ages of 30 and 40 $(62.4\%)$. The average age of these patients was 41.3 years and there was no difference between the genders. $81.4\%$ of these patients underwent CLO test to check for the existence of Helicobacter and $66.3\%$ of these Patients showed the positive response. $65.6\%$ of patients with GU and $80\%$ of patients with DU showed the positive response and there was no difference between the genders $(65.4\%\;vs.\;67.6\%)$. 184 patients $(81.4\%)$ were deemed to be cured based on the disappearance of their symptoms after completing the regimens. Compliance rate did not differ for gender or different diseases, while showing a difference in age. Patients between the ages of 20 to 30 years old showed the worst compliance rate. In addition, the compliance was lower among the patients who had previous occurrence of the disease, and this was more evident among female patients. Although 184 patients out of the total 226 patients were deemed to be cured, 36 patients $(20.65\%)$ of these returned to the hospital for relapsed diseases within one year. The factors that affected for patients to relapse were the diseases accompanied by ulcer and social environments, such as smoking, alcohol consumption, and previous history of the diseases (smoking P<0.001, alcohol consumption P<0.02, previous history of disease P<0.05). The regimen using $H_2$ receptor antagonists+tripotassium dicitrato bismuthate+clarithromycin showed the lower rate of relapse, and the regimens of omeprazole (OMP)+amoxicillin+tripotassium dicitrato bismuthate and OMP+amoxicillin+metronidazole showed better compliance rate. Patient education by pharmacists on the importance of compliance to regimens and the risk factors fer relapse can provide a better patient care. This would ultimately result in more cost-effective treatments by preventing additional cost for treating relapsed symptoms in approximately $20\%$ of patients.

Expression in the periplasm of Escherichia coli of cloned heavy and light chain cDNAs for Fab fragment of a murine monoclonal antibody MabB9 (${\gamma}2b$, K), specific for human plasma apolipoprotein B-100 of LDL, was studied. For the purpose, a vector for two-cistronic expression of the heavy chain cDNA, at the 5' terminus, and light chain cDNA, at the 3' terminus, was constructed using the signal sequences, pelB (for heavy chain) and ompA (for light chain) in a pET vector system. The constructed vector was transformed into E. coli BL21(DE3). The expressed heavy chain (25 kDa) and light chain (23 kDa) of the antibody molecule were detected in total cell extracts as well as in the periplasmic extracts of E. coli.

Sera from rabbits were infected with Vibrio vulnificus containing an antibody against major outer membrane protein (MOMP). MOMP of V. vulnificus ATCC 27562 were isolated and purified by Sarkosyl and TritonX-100 dual treatment. Molecular size of MOMP was identified as 36-kDa on $13\%$ SDS-PAGE. The sequence of the first 26 amino acid residues from the N-terminal end of the protein is AELYNQDGTSLDMGGRAEARLSMKDG, which is a perfect match with OmpU of V. vulnificus CMCP6 and YJ016. MOMP specific IgM and IgG were investigated in groups of mice. The group of mice immunized with MOMP and Alum showed higher levels of IgG2b than the group immunized with only MOMP. Vaccination with MOMP resulted in protective antibodies in the mouse infection experiment.

In this paper, we propose an algorithm that jointly estimates the location and velocity of a near-field moving target in a pulse radar system. The proposed algorithm estimates the location and velocity corresponding to the outcome of orthogonal matching pursuit (OMP) in a 4-dimensional (4D) location-velocity space. To address the high computational complexity of 4D parameter joint estimation, we propose an algorithm that iteratively estimates the target's 2D location and velocity sequentially. Through simulations, we analyze the estimation performance and verify the computational efficiency of the proposed algorithm.

인간 과립구 성장인자(hG-CSF)는 골수에서 생산되는 단백질로 호중구의 분화 및 생성을 촉진시키는 역할을 한다. 현재 재조합 hG-CSF는 암화학요법에 의한 호중구감소증, 골수이식시 호중구 감소증, 재생불량성 빈혈에 수반되는 호중구 감소증 등으로 적응증이 확대되고 있다. 본 연구에서는 OmpA signal sequence를 삽입하여 인간 과립구 성장인자(hG-CSF)가 분비발현되도록 고안된 T7 promoter 에 의하여 발현되는 pYRCl 발현백터를 제조하였다. E. coli BL2l (pYRCl) 발현시 $37^{\circ}C$에서 배양하는 경우 많은 양의 봉입체(aggregates)를 형성한다. 이에 비하여 $10\mu$M ucose를 포함하는 변형된 MBL배지에서 10 g/$\ell$IPTG를 유도물질로 7시간동안 $25^{\circ}C$에서 배양하였을 때 전체 periplasm단백질의 15%가 soluble rhG-CSF이었다. 또한, 유가식 배양방법을 사용하여 E. coli BL2l(pYRCl)에서 soluble rhG-CSF의 생산조건을 조사하였다. 유가식 배양에서 rhG-CSF의 발현량이 비증식속도를 $0.43 h^{-1}$ 에서 0.14 $h^{-1}$ 으로, 유도 배양시간을 최적화함으로써 rhG-CSF의 발현량이 4.4mg/$\ell$에서 24mg/$\ell$ 로 증가하였다.

Objective : As part of the Korean Medicine Official Development Assistance(ODA) and Public Health Project, we implemented a obesity management program(OMP) using Korean medicine in Uzbekistan and its follow-up study was conducted to evaluate the effectiveness of the program. Method : We recruited the participants of whose Body Mass Index(BMI) were over $25kg/m^2$ and who agreed to participate in the program at the South Korea-Uzbekistan Friendship Korean Medical Hospital in Uzbekistan. The program consisted of auricular acupuncture, functional food, and education program on diet and exercise. It was provided once a week during 7-week period. Anthropometric measurements and blood test measuring total cholesterol, triglyceride, and glucose were performed at the baseline, the end of the program, and 10-month follow-up. At the end of the program and the follow-up, survey on satisfaction and self-evaluation of the effectiveness of the program was additionally conducted. Results : 43 out of 78 participants completed the program and were included in the analysis. The analysis of the main outcomes showed that there were significant decreases in anthropometric measurements such as body weight, waist circumference, body mass index (BMI) and body fat content as well as blood test including triglycerides, total cholesterol and blood glucose levels. In the follow-up study, 24 subjects participated and 19 subjects (79.1%) reported that they succeeded in weight control. Furthermore, many participants reported that they maintained healthy lifestyles like healthy diet and regular exercise. The satisfaction with the program was also relatively high, and the education program was selected as the most motivating intervention for weight control. The outcomes such as body weight, BMI, body fat content, and blood glucose level were maintained to be at the decreased level; however, waist circumference, total cholesterol and triglycerides levels either returned back to the baseline level or were elevated to the level higher than the baseline. Conclusion : This study suggests that the OMP using Korean medicine may contribute to weight control of obese population in Uzbekistan. It is meaningful in that the study shows the possibility of implementing health promotion programs using Korean medicine in other countries with different cultures. In the future, more efforts to evaluate the effectiveness of the programs using rigorous methodologies and utilize the effective programs in ODA project will be needed.

A new UV-curable coating was carried out to impart the flame-retardant property to cotton fabric using Bis[2-(methacryloyloxy)ehtyl]phosphate(DMEP) and 2-hydroxy-2-methyl-1-phenyl-propan-l-one(HMPP) as a UV-curable monomer and a photoinitiator, respectively. The cotton fabrics were applied with various amounts of DMEP and HMPP via padding and UV irradiation, and the optimal concentrations of DMEP and HMPP in the formulation were 40%(w/w) and 7%omp respectively. A limiteed oxygen index(LOI) up to 28.9 was obtained for the UV-cured fabric, which may occur through a condensed phase mechanism as verified by the increased residue number with increased application level. The characterization of the UV-cured coating was made by IR analysis, thermo-gravimetric analysis, LOI test, and scanning electron microscopy.
