Background : This study was conducted to developed the propagation method by cutting for mass cultivation of Vitex roundifolia. We were pitched the cutting two times and treated plant growth regulators to enhance the rooting percentage. Vitex roundifolia is live in beach sandy soil south of Hwanghae-Do and Gangwon-Do. Vitex roundifolia have been used to bath foam. It is good for aromatic plant. It has 0.8% essential oil content in leaf and flower. Major components of essential oil were alpha-Pinene, Sabinene, beta-Pinen, 1,8-cineole, d-Limone. Despite the superior usability, it had not yet been made by the artificial cultivation Methods and Results : We were pitched the cutting of a first-year branch on June 5, which was greenwood cutting and July 17, which was semi-hardwood cutting at Kwangseung-ri beach, Gochanggun, Jeonbuk. The length of cutting was 10cm. It had 3~4 nodes, we stuck a cutting remain 2 nodes above ground on ordinary raise seedling soil. Rooting percentage was measured at 60 days after stuck a cutting. Rooting percentage was higher greenwoody cutting(95%) than semi-hardwood cutting(57.6%). In green wood cutting, there was no significance with plant growth, but chemical injury was occurred in IBA 5,000ppm. In semi-hardwood cutting, there was significance with plant growth regulators. The rooting percentages of all the treat were higher than control(no treatment). Rooting percentage was the highest in NAA 5,000ppm treated. Conclusion : Greenwood cutting method was more proper to propagation for Vitex roundifolia than semi-hardwood cutting. The optimum time to cutting for Vitex roundifolia propagation was the early in June. If miss a time to propagation Rooting percent was elevated by plant growth regulator.

For the recent 5-6 years, the ratio of smart phone users in South Korea has increased to over 65% of cellular subscribers and half of all population. While smartphones have given enormous convenience to our lives, pathological use of smartphones has brought a new mental health concern among the community. Therefore, huge interest sheds on the studies on the cause analysis and treatment of smartphone addiction. However, the traditional clinic approach based survey and interview has serious drawbacks of its subjectivity and inability of continual monitoring and treatment. In this paper, SAMS (smartphone addiction management system) is presented, which monitors the application usage pattern, provides statistical analysis, and policy-based usage intervention. A trail test is performed for checking he reliability and efficacy of SAMS in smartphone addiction research, and some analysis on the collected data are done: daily use count, not daily use time, has strong influence on smartphone addiction: CC=0.62 and CC =0.00 for the correlation coefficients of counts and times with total survey score, and p = 0.047 and p = 0.507 for t-test analysis of contrast group.

Background/Aims: Data regarding the prognosis of early esophageal cancer are lacking. This study investigated the long-term outcomes and factors affecting the survival of patients with mucosal esophageal squamous cell carcinoma (T1aESCC). Methods: We analyzed the clinical and tumor-specific parameters of 263 patients who received surgical resection (SR; n=63) or endoscopic resection (ER; n=200) for T1aESCC. Underlying comorbidities were scored using the Charlson comorbidity index (CCI). Overall survival (OS) was the primary outcome, and multivariate regression analysis was performed to predict factors for OS. Results: Of the study patients (age, 64.5±8.0 years), the CCI was 1.0±1.4 in the ER group and 0.6±0.9 in the SR group (p=0.107). The 5-year OS rate during follow-up (54.4±20.4 months) was 85.7% (ER group, 86.8%; SR group, 82.4%; p=0.631). The cumulative 5-year incidence of esophageal cancer recurrence was 10.5% in the ER group (vs 0% in the SR group). The overall mortality rate was 12.9% (ER group, 12.0%; SR group, 15.9%; p=0.399). The most common cause of mortality was second primary cancers in the ER group (75%) and organ dysfunction or postoperative complications in the SR group (70%). According to multivariate analysis, only CCI was significantly associated with OS (p< 0.001). The 5-year OS rate in patients with a CCI >2 and in those with a CCI ≤2 was 60.2% and 88.2%, respectively (p<0.001). The treatment method (ER vs SR) was not a significant affecting factor (p=0.238). Conclusions: The long-term prognosis of patients with T1aESCC was significantly associated with underlying comorbidities. (Gut Liver 2021;15:705-712)
인터넷 기반 슬롯머신(EGM) G2S(game to systems) 프로토콜 엔진 설계

The international casino game industry has adopted G2S (game to systems) protocol for the future communication standards between slot machines and gaming hosts. G2S protocol uses the internet protocols and XML message format. Not simply G2S protocol replaces the SAS protocol currently in use but with many limitations, but provides diverse application and business chances to the casino industry. In this paper, we introduce the overview of technical features of G2S system, and describe our design and implementation experience of core G2S protocol engine for slot machine devices. The G2S engine provides key protocol stack of G2S (HTTP, XML, and SOAP) and runtime services, using open source softwares and custom classes. The protocol compatibility of the implemented G2S engine is confirmed against an openG2S host software contributed by IGT. Also the measured memory size and perfroamcne is compact enough for typical slot machine hardware specification.

Background/Aims: Epstein-Barr virus (EBV) and Helicobacter pylori (HP) coinfection may synergistically induce severe inflammatory responses in the stomach tissue, increasing the risk of developing gastric cancer. We aimed to analyze the effect of EBV and HP coinfection on the clinicopathologic features and prognosis of gastric cancer, as well as to evaluate the role of EBV infection in non-gastric carcinoma with lymphoid stroma (non-GCLS). Methods: Overall, 956 patients who underwent surgery for gastric cancer between September 2014 and August 2015 were eligible and divided into groups, according to GCLS morphology, EBV infection, and HP infection. Clinicopathologic characteristics and oncologic outcomes were analyzed retrospectively. Results: EBV and HP coinfection was significantly associated with male sex, proximal location, GCLS morphology, and equivocal p53 expression (p<0.001). Multivariate analysis revealed that EBV infection alone (hazard ratio [HR], 0.362; 95% CI, 0.131 to 0.996; p=0.049) and lower third location (HR, 0.624; 95% CI, 0.413 to 0.943; p=0.025) were inversely correlated with overall survival. During median follow-up period of 72 months, overall survival rate was not significantly different between the EBV and HP coinfection group and others (97.6% vs 86.8%, log-rank p=0.144). In non-GCLS patients (n=920), overall survival rate was not significantly different between the EBV infection group and others (96.9% vs 86.4%, log-rank p=0.126). Conclusions: EBV and HP coinfection is not an independent prognostic factor for gastric cancer. EBV infection status, regardless of HP infection, affects the clinicopathologic features of all types of gastric cancer. However, it does not lead to a significant difference in overall survival of non-GCLS patients.

Background/Aims: The aim of this study was to compare the effects of erythromycin infusion and gastric lavage in order to improve the quality of visualization during emergency upper endoscopy. Methods: We performed a prospective randomized pilot study. Patients presented with hematemesis or melena within 12 hours and were randomly assigned to the erythromycin group (intravenous infusion of erythromycin), gastric lavage group (nasogastric tube placement with gastric lavage), or erythromycin + gastric lavage group (both erythromycin infusion and gastric lavage). The primary outcome was satisfactory visualization. Secondary outcomes included identification of a bleeding source, the success rate of hemostasis, duration of endoscopy, complications related to erythromycin infusion or gastric lavage, number of transfused blood units, rebleeding rate, and bleeding-related mortality. Results: A total of 43 patients were randomly assigned: 14 patients in the erythromycin group; 15 patients in the gastric lavage group; and 14 patients in the erythromycin + gastric lavage group. Overall satisfactory visualization was achieved in 81% of patients: 92.8% in the erythromycin group; 60.0% in the gastric lavage group; and 92.9% in the erythromycin + gastric lavage group, respectively (p = 0.055). The identification of a bleeding source was possible in all cases. The success rate of hemostasis, duration of endoscopy, and number of transfused blood units did not significantly differ between groups. There were no complications. Rebleeding occurred in three patients (7.0%). Bleeding-related mortality was not reported. Conclusions: Intravenous erythromycin infusion prior to emergency endoscopy for acute nonvariceal upper gastrointestinal bleeding seems to provide satisfactory endoscopic visualization.

Purpose: To evaluate the clinical symptoms and the associated intra-articular disorders of the polpliteal cyst. Materials and Methods: We studied 56 patients, 60 cases of the popliteal cysts which had been treated with excision of the cyst after arthroscopy between May 1991 and February 2000. Arthroscopic findings and clinical results of the patients who had popliteal cyst were evaluated. Results: Forty nine patients of the sixty patients of who had popliteal cyst showed intra-articular disorders. Tear of the meniscus and patello-femoral arthrosis with cartilage lesions were the most frequent intra-articular lesions. In 4 cases, recurrence of the popliteal cyst was noted. Two patients had tear of the meniscus and two had no intra-articular disorders. Conclusion: This study revealed that popliteal cysts frequently combined with intra-articular disorders. Arthroscopy of the knee joint seems worthwhile method for the patients who had popliteal cyst
