Laparoscopic appendectomy is relatively well-established as an alternative to conventional open appendectomy by many laparoscopic surgeons. However, experience in the pediatric population remains limited. Over a period of 2 years, a total of 155 pediatric patients with acute appendicitis or complicated appendicitis were studied to compare laparoscopic and open appendectomies in childhood. Laparoscopic appendectomy was attempted in 49 patients and completed in 48 patients(98.0%). Open appendectomy was performed in 107 patients. The severity of disease, age, and male to female ratio were similar in both groups. The operation time was shorter in the laparoscopic group than open group but the difference was not significant statistically($43.7{\pm}11.3$ minutes versus $49.0{\pm}21.4$ minutes, p=0.066). In the laparoscopic group, the mean duration of surgery for the former half patients was significantly longer than for the latter half($49.6{\pm}9.2$ minutes versus $38.1{\pm}10.3$ minutes, p=0.001). The mean number of doses of analgesia required postoperatively was significantly less in patients undergoing laparoscopic appendectomy($2.4{\pm}1.8$ versus $3.3{\pm}2.5$, p=0.021). There were only 2(4.2%) wound infections after laparoscopic appendectomy compared with 10(9.3%) complications including 7 wound infections, 1 intestinal obstruction, and 2 pulmonary complications after open appendectomy, but the difference was not significant(p=0.614). Patients undergoing laparoscopic appendectomy had a shorter period of hospitalization($3.2{\pm}2.2$ days versus $6.4{\pm}1.6$ days. p=0.001). The present study suggests that laparoscopic appendectomy shortens operating time and hospital stay with diminished postoperative pain. Laparoscopic appendectomy in children offers advantages over open appendectomy as noted in adults. The authors consider laparoscopic appendectomy to be the reasonable alternative to open appendectomy in children.

Omni-channel strategy is an innovative paradigm for integrated information distribution of inventory, sales, operations, marketing, delivery, pickups and returns in supply chain management. Recently the distribution strategy faces new challenges with the advent of mobile distribution channels. Social media with countless apps imposes additional stress on supply chain operations. Due to these changes, distribution network in supply chain is changing naturally and rapidly from multi-channel to omnni-channel platform. Recently numerous domestic distributors establish and adapt this new supply chain optimization tool as a part of seamless flow of movements of goods from one channel to other channels. The objective of this paper is to present a preliminary findings on how omnni-channel affects the supply chain management. A survey is used to ascertain in the degree of omnni-channel implementation and statistical evidence is provided to test sets of hypothesis. The results of the questionnaire showed that consumers' purchasing styles differed by gender, age, purchase purpose, and product type. In particular, women consider purchasing experience in omni-channel to be important. As food and household goods can be conveniently shipped, consumers prefer online purchasing it. Conversely, consumers tend to favor omni-channel strategy in connection with offline experience in IT products.

Objectives This research was proposed to present Clinical Practice Guideline (CPG) for Prevention of Sasangin disease pattern of Sasang Constitutional Medicine (SCM) and diseases closely related with Sasang constitution. Each CPG was developed by the national-wide experts committee consisting of SCM professors. Methods At first, we searched the literatures related to SCM such as "Dongeuisusebowon", Textbook of SCM and Clinical Guidebook of SCM. Also we searched the articles related to the studies about risk factors for Sasangin disease pattern of both at home and abroad. Finally, we selected leading risk factors of Sasangin disease pattern and developed CPG for prevention of Sasangin disease pattern of SCM. And then, we searched the literatures related SCM such as "Dongeuisusebowon" and the articles on the correlation between disease and Sasang constitution using case-control studies, observational studies or cross sectional studies of both at home and abroad. Next, we selected diseases closely related with Sasang constitution on the basis of articles including prevalence rate and odds ratio between disease and Sasang constitution and finally developed CPG for these diseases. Results and Conclusions We categorized risk factors of Sasang disease pattern into 2 types: non-modifiable and potentially modifiable. 3 items (age, sex and genetic factors) were classified as non-modifiable risk factors of Sasang disease pattern. 6 items (original symptom, stress, diet and nutrition, physical activity, alcohol and drug misuse) were classified as less well-documented or potentially modifiable risk factors of Sasangin disease pattern. We found out Sasang constitution is more likely to develop some diseases. It was proven that Sasang constitution increase the risk of hypertension, diabetes mellitus, metabolic syndrome, stroke, nonalcoholic fatty liver and obstructive sleep apnea. And there is high probability of Sasang constitution being potential risk factor for obesity, hyperlipidemia, allergy and cancer. Also, we found out Taeeumin is independent risk factor for hypertension, diabetes mellitus, metabolic syndrome, stroke, nonalcoholic fatty liver and obstructive sleep apnea. Therefore we recommend that Taeeumin need to prevent these disease by regular checkups and aggressive management.

Aberrant hypermethylation of Wnt antagonists has been observed in gastric cancer. A number of studies have focused on the hypermethylation of a single Wnt antagonist and its role in regulating the activation of signaling. However, how the Wnt antagonists interacted to regulate the signaling pathway has not been reported. In the present study, we systematically investigated the methylation of some Wnt antagonist genes (SFRP2, SFRP4, SFRP5, DKK1, DKK2, and APC) and their regulatory role in carcinogenesis. We found that aberrant promoter methylation of SFRP2, SFRP4, DKK1, and DKK2 was significantly increased in gastric cancer. Moreover, concurrent hypermethylation of SFRP2 and DKK2 was observed in gastric cancer and this was significantly associated with increased expression of ${\beta}-catenin$, indicating that the joint inactivation of these two genes promoted the activation of the Wnt signaling pathway. Further analysis using a multivariate Cox proportional hazards model showed that DKK2 methylation was an independent prognostic factor for poor overall survival, and the predictive value was markedly enhanced when the combined methylation status of SFRP2 and DKK2 was considered. In addition, the methylation level of SFRP4 and DKK2 was correlated with the patient's age and tumor differentiation, respectively. In conclusion, epigenetic silencing of Wnt antagonists was associated with gastric carcinogenesis, and concurrent hypermethylation of SFRP2 and DKK2 could be a potential marker for a prognosis of poor overall survival.

Egg is a food that has been loved from ancient times by people all around the world. It has been called a present from god because its rounded shape was believed to refer to the earth. We found the oldest and most perfectly preserved egg fossil at Chunmachong (天馬) in Kyungju (慶州). We believe that it was used during the period of the Three States or the unified Silla (新羅), and, accordingly, it was a noble food that has been found at the king's grave of the age. Egg, which is called egg of chicken in Korean, was written as egg of chicken (鷄卵), son of chicken (鷄子), bird's egg of chicken (鷄蛋), and round thing of chicken (鷄丸) in the Korean alphabet and Chinese characters. The ancient countries had the following myths about eggs In myths about offspring by egg, they were born as heaven's will to make them god. There were 19 proverbs: 'Hitting a rock with an egg', 'It's like the yellow part of an egg' and 'Even an egg stops when it rolls', etc. According to a theory of divination based on topography, people use eggs when they find a good place. There are 10 proverbs (四字 成語): Dongjiipran (冬至立卵), Nanyeoseoktu (卵與石投) etc. Studies for analysis of egg recipes found in the old literature (cooking, agriculture and fishing, and medical books) in the Chosun Dynasty recorded 36 times where cuisine with egg was mentioned as the main ingredient, 154 times as a sub-ingredient, 79 times as a garnish, and 20 times etc. As a garnish, they were 'finely sliced', 'thin rectangular and the rhombus form', and 'rounded shape'; after grilling they were divided into yellow and white parts. When cooked, they were used in comparison of the size or shape of an object with that of other objects.

Objectives: Metabolic syndrome is a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease. Associations between metabolic syndrome and several types of cancer have recently been documented. Methods: We analyzed the sample cohort data from the Korean National Health Insurance Service from 2002, with a follow-up period extending to 2013. The cohort data included 99 565 individuals who participated in the health examination program and whose data were therefore present in the cohort database. The metabolic risk profile of each participant was assessed based on obesity, high serum glucose and total cholesterol levels, and high blood pressure. The occurrence of cancer was identified using Korean National Health Insurance claims data. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazards models, adjusting for age group, smoking status, alcohol intake, and regular exercise. Results: A total of 5937 cases of cancer occurred during a mean follow-up period of 10.4 years. In men with a high-risk metabolic profile, the risk of colon cancer was elevated (HR, 1.40; 95% CI, 1.14 to 1.71). In women, a high-risk metabolic profile was associated with a significantly increased risk of gallbladder and biliary tract cancer (HR, 2.05; 95% CI, 1.24 to 3.42). Non-significantly increased risks were observed in men for pharynx, larynx, rectum, and kidney cancer, and in women for colon, liver, breast, and ovarian cancer. Conclusions: The findings of this study support the previously suggested association between metabolic syndrome and the risk of several cancers. A high-risk metabolic profile may be an important risk factor for colon cancer in Korean men and gallbladder and biliary tract cancer in Korean women.

Propionibacterium acnes (P. acnes) plays an important role in the disease pathogenesis of acne vulgaris, a disorder of pilosebaceous follicles, seen primarily in the adolescent age group. In the present study, the presence of antibodies against P. acnes (MTCC1951) were detected in acne patient (n=50) and disease free controls (n=25) using dot-ELISA and Western blot assay. The ability of P. acnes to induce pro-inflammatory cytokines by human peripheral blood mononuclear cells (PBMCs), obtained from acne patients and healthy subjects, were also analysed. The patients (n=26) who were culture positive for skin swab culture, were found to have a more advanced disease and higher antibody titres (1:4000 to >1:16000) compared to the P. acnes negative patients (n=24) and normal controls (n=25). An analysis of patients' sera by western blot assay recognized a number of antigenic components of P. acnes, rang-ing from 29 to 205 kDa. The major reactive component was an approximately 96 kDa polypeptide, which was recognised in 92％ (24 of 26) of the patients sera. Further, the P. acnes culture supernatant, crude cell lysate and heat killed P. acnes whole cells, obtained from 72-h incubation culture, were observed to be able to induce significant amounts of IL-8 and tumor necrosis factor alpha (TNF-${\alpha}$) by the PBMCs in both the healthy subjects and patients, as analysed by cytokine-ELISA. The levels of cytokines were significantly higher in the patients than the healthy subjects. A major 96 kDa polypep-tide reactant was eluted from the gel and was found to cause dose dependent stimulation of the pro-ductions of IL-8 and TNF-${\alpha}$. Thus, the above results suggest that both humoral and pro-inflammatory responses play major roles in the pathogenesis of acne.
