Background/Aims: Although laparoscopic fundoplication is a well-established therapy for gastroesophageal reflux disease (GERD) in Western countries, the mainstay of GERD treatment in Korea is long-term proton pump inhibitor (PPI) use. The aim of the present study was to evaluate nationwide data regarding antireflux surgery in Korea. Methods: Data from 2011 to 2014 were collected from the Korean Antireflux Surgery Study Group and then analyzed. Results: A total of 87 patients underwent laparoscopic fundoplication for the treatment of GERD. Preoperatively, typical symptoms were present in 81 patients (93%) and atypical symptoms were present in 51 patients (59%). Twenty-seven patients (31%) had poor PPI responses. The average surgical time and postoperative hospital stay were 116.3±42.3 minutes and 4.3±3.1 days, respectively. At 3 months after surgery, typical symptoms were completely controlled in 86.3% of patients and partially controlled in 11.7%, whereas atypical symptoms were completely controlled in 63.3% of patients and partially controlled in 23.3%. Conclusions: This study showed that although atypical symptoms and PPI nonresponders are common, the complete control rates of typical and atypical symptoms were 86.3% and 63.3%, respectively. Laparoscopic fundoplication is an efficacious method of controlling the symptoms of GERD and has an acceptable rate of postoperative morbidity and adverse symptoms. (Gut Liver 2016;10:726-730)

Jun Bae Bang,Jae Myeong Lee,Chang-Kwon Oh,Kyo Won Lee,Jae Berm Park,Sung Joo Kim,Su Hyung Lee 대한외과학회 2017 Annals of Surgical Treatment and Research(ASRT) Vol.92 No.3

Transplantation of the horseshoe kidney can be performed en bloc or split into 2 grafts according to the vascular anomaly and the existence of the urinary collecting system in isthmus. From 2011 to 2014, there were 3 horseshoe kidney transplantations in Korea and transplantations were performed at 2 different centers. The transplantations were carried out successfully for all recipients without complications. All recipients have shown good graft kidney function after transplantation. No severe complication was revealed during follow-up period. We described the surgical technique used in the en bloc method to overcome various vascular anomalies and difficulties in choosing cannulation site and postoperative complications. En bloc transplantation of a horseshoe kidney is a useful strategy for patients with end-stage renal disease, and can provide favorable outcomes compared to the transplantation of a normal kidney.

A Study on the Opt-in Marketing

Won-Kyo OH,Won-Jun LEE 한국유통과학회 2020 The Journal of Industrial Distribution & Business( Vol.11 No.2

Purpose: Online and social media and mobile shopping are increasing and companies are required to provide personal information in order to supplement the non-invasive characteristics of the channels. With the increased provision of personal information, consumers' personal and social concerns about the prevention of personal information infringement are also increasing, and in response, personal or opt-in marketing has emerged to compensate for reckless information abuse. Despite the background of this emergence, the existing prior studies are limited to ignoring the negative feelings of consumers in the real world, including only the net function and positive effect of the opt-in mail. Research design, data and methodology: The research framework was intended to utilize the impact of human marketing activities on consumer attitudes combined with positive and negative factors. Factors that positively affect attitudes toward permation marketing were presented, such as informality, and perceived risks were presented as negative impact factors. Also, based on previous prior research, the prior factors of opt-in marketing were to present the effect on purchase intent through the medium of attitude toward opt-in marketing. Results: In this study, we used the framework of a two factor theory to address positive and negative factors as a leading factor in the customer attitude toward opt-in mail advertising, and as a result, functionality and personalization have a positive effect on customer attitude and perceived risk have a negative impact on customer attitude. In addition, it was confirmed that the customer attitude formed this way affects the intention to purchase again. Conclusions: This study suggests that we have demonstrated that marketing, an opt-in marketing that has been recognized as part of marketing that is deployed after obtaining customer consent, has been applied without any other marketing methodology. E-mail advertising at this point also provides practical implications that the system safeguards are in place under an opt-in protocol or system, and that even if an e-mail advertisement is carried out, customers will need to look at the level of awareness about the risks, and suggests that they need to consider the customer’s journey that could lead to purchase at the content level.

Objective We aimed to investigate the annual incidence and direct medical cost of adjustment disorder in general population using the National Health Insurance Service Database (NHID) in Korea. Methods To examine the incidence, we selected patients who had at least one medical claim for adjustment disorder and had not been diagnosed in the previous 365 days, from 2010 to 2017. Results The number of newly diagnosed cases of adjustment disorder from 2011 to 2017 were total 101,922. Annual incidence of adjustment disorder was ranged from 22.0 to 36.8 per 100,000 persons. The incidence of adjustment disorder was found more in female and highest among 70-79 years of age group and medical aid beneficiaries group. Annual prevalence of adjustment disorder was in the range from 95.4 to 116.4 per 100,000 persons. Estimated annual medical cost per person of adjustment disorder was ranged from 162 to 231.4 US dollars. Conclusion From 2011 to 2017, the annual incidence and direct medical cost of adjustment disorder in Korea were increased. Proper information on adjustment disorder will not only allows us to accumulate more knowledge but also lead to more appropriate therapeutic interventions.

Background/Aims: Gallstone pathogenesis is linked to mucin hypersecretion and bacterial infection. Several mucin genes have been identified in gallbladder epithelial cells (GBECs). We investigated MUC expression in cholesterolassociated gallbladder disease and evaluated the relationship between mucin and bacterial infection. Methods: The present study involved 20 patients with cholesterol stones with cholecystitis, five with cholesterol stones with cholesterolosis, six with cholesterol polyps, two with gallbladder cancer, and six controls. Canine GBECs treated with lipopolysaccharide were also studied. MUC3, MUC5AC, MUC5B, and MUC6 antibodies were used for dot/slot immunoblotting and immunohistochemical studies of the gallbladder epithelial tissues, canine GBECs, and bile. Reverse-transcription polymerase chain reaction was performed to evaluate MUC3 and MUC5B expression. Results: MUC3, MUC5AC, MUC5B, and MUC6 were expressed in the normal gallbladder epithelium, and of those, MUC3 and MUC5B exhibited the highest expression levels. Greatly increased levels of MUC3 and MUC5B expression were observed in the cholesterol stone group, and slightly increased levels were observed in the cholesterol polyp group; MUC3 and MUC5B mRNA was also upregulated in those groups. Canine GBECs treated with lipopolysaccharide also showed upregulation of MUC3 and MUC5B. Conclusions: The mucin genes with the highest expression levels in gallbladder tissue in cholesterol-associated diseases were MUC3 and MUC5B. Cholesterol stones and gallbladder infections were associated with increased MUC3 and MUC5B expression. (Gut Liver 2016;10:851-858)

Case Report : Acute Pancreatitis Complicating Spontaneous Acute Exacerbation of Chronic Hepatitis B Virus Infection: Case Report and Review of the Literature

( Kyo Sang Yoo ),( Kyung Hun Lee ),( Kyung Rim Huh ),( Won Sub Choi ),( Gang Jeon ),( Jun Wook Ha ),( Kyoung Oh Kim ),( Cheol Hee Park ),( Tae Ho Hahn ),( Sang Hoon Park ),( Jong Hyeok Kim ),( Choong The Editorial Office of Gut and Liver 2009 Gut and Liver Vol.3 No.1

Acute pancreatitis may complicate viral hepatitis B, as well as the other causes of viral hepatitis. There have been reports of acute pancreatitis complicating acute exacerbations of chronic hepatitis B virus infection, most of which were related to immunosuppressive treatment or organ transplantation. However, acute pancreatitis complicating spontaneous acute exacerbation of chronic hepatitis B virus infection is rare. We report a case of acute pancreatitis that developed while a spontaneous acute exacerbation of chronic hepatitis B virus infection was underway in a healthy carrier. (Gut and Liver 2009;3:64-66)

( Jun Hyeok Kang ),( Se Hyun Nam ),( Taejong Song ),( Woo Young Kim ),( Kyo Won Lee ),( Kye Hyun Kim ) 대한산부인과학회 2015 Obstetrics & Gynecology Science Vol.58 No.4

Objective: The fallopian tube is considered as the site of origin of serous ovarian cancer, and risk-reducing salpingectomy (RRS) has been proposed as a new and safe strategy for preventing ovarian cancer. However, little is known about the public perception of RRS. Methods: We performed a questionnaire survey of 100 healthy female volunteers in November 2014. Questionnaire for this survey included questions on demographics, medical history, knowledge of and belief about RRS, and barrier to its application. Results: Among 100 respondents, 71% did not realize the seriousness of ovarian cancer, 79% were unaware of the fact that salpinx was the origin of ovarian cancer, and 87% stated that they had never heard of RRS as a preventive method for ovarian cancer. Also, 98% of respondents replied that they had the right to be informed about RRS and the choice given. The respondents’ fears about RRS included increased risk of surgical complications (68%), no benefit (8%), and increased surgical costs (3%). Conclusion: Most general women were unaware of RRS as a method for preventing ovarian cancer in women at average risk. Therefore, physicians should discuss RRS with patients and consider this procedure at the time of abdominal or pelvic surgery.

Charge Migration Analysis of 3D SONOS NAND Flash Memory Using Test Pattern

Jun-Kyo Jeong,Jae-Young Sung,Hee-Hoon Yang,Hi-Deok Lee,Ga-Won Lee 대한전자공학회 2020 Journal of semiconductor technology and science Vol.20 No.2

In this study, new test patterns to evaluate the charge migration in 3D SONOS NAND flash memory are suggested. The charge migration in Si3N4, the charge trapping layer of SONOS is an important factor affecting the performance of the memory. To analyze the charge migration based on the proposed test pattern, the device was fabricated with a capacitor structure, and the charge loss and retention properties were measured by capacitance-voltage analysis. The charge loss due to lateral migration and vertical migration can be separately calculated using the test pattern. In addition, the activation energy was extracted to identify the cause of charge migration. This study is expected to contribute to the reliability problem of charge migration of 3D NADN Flash memory.

Downscaling Study of Uncooled a-Si Infrared Microbolometer Cell based on Simulation

Jun-Kyo Jeong,Byeong-Jun Jeong,Jae- Sub Oh,Ga-Won Lee 대한전자공학회 2020 Journal of semiconductor technology and science Vol.20 No.1

This study analyzes the response time, that is, thermal time constant of an uncooled amorphous silicon (a-Si) infrared (IR) microbolometer cell based on simulation when the device is downscaled for higher resolution. For accurate analysis, an 8080 array of a-Si microbolometer was fabricated with a 35 μm pixel size. The real device was used to extract the external environmental parameter for the simulation where temperature coefficient of resistance (TCR) of a-Si is also modeled to include temperature-dependence. It is known qualitatively that the cell geometries like as the length of the resistance layer and width of the leg are key factors for the time constant of the device. When the pixel is downscaled to 17 μm, the time constant is found to increase as the length of the resistance layer becomes narrower, but this tendency is reversed for the width of the leg. This is because the influence of each component on the total resistance is changed according to the cell area, which is efficiently optimized by the simulation analysis.
