Backgrounds/Aims: No reports to compare incisional hernia (IH) incidence between laparoscopic and open colorectal liver metastases (CRLM) resections have previously been made. This is the first comparative study. Methods: Single-center retrospective review of patients who underwent CRLM surgery between January 2011 and December 2018. IH relating to liver surgery was confirmed by computed tomography. Patients were divided into laparoscopic liver resection (LLR) and open liver resection (OLR) groups. Data collection included age, sex, presence of diabetes mellitus, steroid intake, history of previous hernia or liver resection, subcutaneous and peri-renal fat thickness, preoperative creatinine and albumin, American Society of Anesthesiologists (ASA) score, major liver resection, surgical site infection, synchronous presentation, and preoperative chemotherapy. Results: Two hundred and forty-seven patients were included with a mean follow-up period of 41 ± 29 months (mean ± standard deviation). Eighty seven (35%) patients had LLR and 160 patients had OLR. No significant difference in the incidence of IH between LLR and OLR was found at 1 and 3 years, respectively ([10%, 19%] vs. [10%, 19%], p = 0.95). On multivariate analysis, previous hernia history (hazard ratio [HR], 2.22; 95% confidence interval [CI], 1.56-4.86) and subcutaneous fat thickness (HR, 2.22; 95% CI, 1.19-4.13) were independent risk factors. Length of hospital stay was shorter in LLR (6 ± 4 days vs. 10 ± 8 days, p < 0.001), in comparison to OLR. Conclusions: In CRLM, no difference in the incidence of IH between LLR and OLR was found. Previous hernia and subcutaneous fat thickness were risk factors. Further studies are needed to assess modifiable risk factors to develop IH in LLR.

The study undertakes an examination of nutrition labelling system and offers a strategic framework for improvement of the system in Korean context. Thus this study includes a review of Korean current nutrition labelling system (NLS), development of a strategy or a further study for its revision of NLS, and a suggestion of revised nutrition labelling guidelines. Participants were 600 university students in Busan and were asked to fill in a questionnaire. The data collected were processed with the SPSS statistical program to produce its frequency, percentage, average, and standard deviation with One-Way Anova and Duncan Test. The findings are as follows: the levels of consumer's practical use and awareness of NLS are low, the levels of their trust and satisfaction and their necessity for NLS are low too. Consequently, the consumer's attitudes to NLS are not related to nutrition labelling method(? system).

In December 1999, the AICPA introduced WebTrust, a electronic commerce assurance service of ensuring safe trading on the web, in order to effect consumer confidence into electronic commerce. Shortly afterwards, CPA associations of other advanced nations, such as Canada, Australia, also adopted this service. This study focuses on introduction of electronic commerce assurance service of ensuring safe trading on the web. WebTrust assurance service expected to be the international standard in electronic commerce in the near future and not only as a source of income for domestic accounting firms, which have simpler income structure than the international counterparts, but also as catalyst for stimulating electronic commerce. The findings of the study are expected to contribute to accounting practice, academy of accounting and electronic commerce firms in the following ways. Domestically, as Korea is considering using the electronic commerce assurance service, this study will help promote adoption of WebTrust assurance service. This study has shown, in the midst of declining income of accounting firms by audit, a way to increase their audit boundary.

The purpose of this study was to examine the knowledge about savings of customers who utilize Investment Trust Company and to analyze the factors affecting it. The data for the analysis were collected by structured questionnaires and consisted of 191 customers who utilize Investment Trust Company. Descriptive. Descriptive Statistics including percentage, frequency, means, and standard derivation, t-test, one-way ANOVA with Scheffe test, multiple regression analysis were used to analyze the data. The following is a summary of major findings. 1) The customers knowledge about savings showed generally low-level. Especially the knowledge about tax and regulation of savings were the areas shown the lowest level. 2) The age, marital status, education and occupation of customers and total period of utilizing company were the factors affecting the knowledge of customers in the one-way ANOVA analysis. 3) The result of regression analysis indicated that age of customers and total periods of utilizing company were the significant predictors of customers’knowledge. These two variables explained 25.77% of variance of customers’knowledge about savings.

The purposes of this study were to verify the effects of HMR (Home Meal Replacement) brand image on purchase intention and brand loyalty. In addition, the mediating role of brand trust was also examined between purchase intention and brand loyalty. This survey was conducted with those who have bought HMR in Seoul and Kyonggi area, Korea, using a convenience sampling method. After a total of 300 responses were collected, 275 were used for the analyses. Both standard and hierarchical multiple regression analyses were conducted to test the hypotheses. The results are as follows. First, it was found that emotional image had an effect on purchase of HMR but that social image did not have an effect on purchase of HMR. Second, purchase intention of HMR significantly impacted brand loyalty. Third, brand trust of HMR was found to mediate the relationship between purchase intention and brand loyalty of HMR. These findings provide practical implication for researchers and marketer regarding relationship marketing strategy in the HMR context.

최근 클라우드의 사용량이 해마다 증가하고 기업 내 원격 근무가 새로운 근무 형태 중 하나로 자리 잡으면서 클라우드 기반 원격 근무 환경의 보안이 중요해졌다. 내부 네트워크 안에 있는 모든 것은 안전하다고 가정하는 기존의 경계 기반 모델의 한계로 인해 제로트러스트 도입이 요구되고 있다. 이에 따라 NIST 및 DoD는 제로트러스트 아키텍처 관련 표준을 발간하였지만, 해당 표준의 보안요구사항은 추상적인 수준에서 논리적 아키텍처만을 기술하고 있다. 따라서 본 논문에서는 OpenStack 클라우드에 대한 위협모델링을 수행하여 NIST 및 DoD 표준에 비해 보다 상세한 보안요구사항을 제시하고자 한다. 이후 본 연구팀은 해당 요구사항에 대한 검증을 위해 상용 클라우드 서비스들에 대한 보안성 분석을 수행하였다. 보안성 분석 수행 결과 본 연구팀에서는 각 클라우드 서비스가 만족하지 못하는 보안요구사항을 식별하였다. 본 연구팀은 제로트러스트가 적용된 클라우드 서비스에 대한 잠재적 위협과 대응 방안을 제안하였으며, 이를 통해 안전한 제로트러스트 기반 원격 근무 환경을 구축하는데 도움이 되고자 한다.

The study was carried out to develope quantitative analysis method of individual sugars in licorice extract. Individual sugars were analyzed by HPLC equipped with Refractive Index(RI) Detector. R values of sucrose and glucose were 1.0000 and R values of fructose and maltose were 0.9999. Standard calibration curve showed good linearity. Detection limit of sugars was in the range of 1.58 to 3.92 ${\mu}g$. Recovery rate of fructose, glucose, sucrose and maltose was $99.4\~102.2\%,\;92.3\~97.9\%,\;99.4\~102.0\%,\;91.1\~101.0$ respectively. Measure uncertainty was calculated to confirm trust and accuracy of analytical results. Main uncertainty factors were standard purity and HPLC replication injection. In $95\%$ trust level expanded uncertainty of sugars in licorice extract were fructose $1.98\pm0.047,\;glucose\;1.32\pm0.065,\;sucrose\;11.69\pm1.177,\;maltose\;1.06\pm0.042\;g/100\;g$.
