Laparoscopic proximal gastrectomy (LPG) is theoretically a superior choice of minimally-invasive surgery and function-preserving surgery for the treatment of proximal early gastric cancer (EGC) over procedures such as laparoscopic total gastrectomy (LTG), open total gastrectomy (OTG) and open proximal gastrectomy (OPG). However, LPG and OPG are not popular surgical options due to three main concerns: the first, oncological safety; the second, functional benefits; and the third, anastomosis-related late complications (reflux symptoms and anastomotic stricture). Numerous recent studies have concluded that OPG and LPG present similar oncological safety profiles and improved functional benefits when compared with OTG and LTG. While OPG with modified esophagogastrostomy does not provide satisfactory results, OPG with modified esophagojejunostomy showed similar rates of anastomosis-related late complications when compared to OTG. At this stage, no standard reconstruction method post-LPG exists in the clinical setting. We recently showed that LPG with double tract reconstruction (DTR) is a superior choice over LTG for proximal EGC in terms of maintaining body weight and preventing anemia. However, as there is no definitive evidence in favor of LPG with DTR, a randomized clinical trial comparing LPG with DTR to LTG was recommended. This trial, the Korean Laparoscopic Gastrointestinal Surgery Study-05 (NCT01433861), is expected to assist surgeons in choice of surgical approach and strategy for patients with proximal EGC.

Purpose : Recently, there has been a growing social interest in aging well. Consequently, wellness tourism has begun to attract attention. However, no studies on whether wellness tourism has any objective health benefits have been carried out yet. In this study, we assess the health benefits as well as the degree of improvement in health of a wellness tourism program. Methods : The study involved 30 adults over the age of 19 who live in the Gyeongsangnam-do region. Participants were evaluated on health indicator before and after participating in wellness tourism program. Participants took heart rate variability (HRV) test, and LFT, RFT, CBC, FBS HbA1C, and CRP test were conducted before and after the tour. Additionally, a survey was conducted before and after the program, and participant satisfaction was evaluated. Statistical differences in the tests conducted before and after the program were analyzed using a design t-test, a Wilcoxon signed-rank test, and McNemar's test. Results : The study showed that participants were very satisfied with and had significant health improvements after the wellness tourism program. The program was also found to be beneficial in improving participants' emotions as follows: BDI (p<.001), fatigue recovery (p=.006), stress relief (p=.003), improved quality of life (p<.05), and improved sleep quality (p<.001). Conclusion : Wellness tourism programs are specifically beneficial for improving participants' emotions (depression, anxiety), fatigue, stress levels, quality of life, and sleep. Therefore, they are beneficial to the overall health. Further research in the future by way of a follow-up study on the long-term effects on health after short-term interventions will provide more validation data.

Recently, yogurt has been extensively studied to further enhance its functions using edible plant extracts. This study was conducted to investigate whether safflower petal (SP) as a natural food additive can be used to develop functional yogurt with improved health benefits. SPs were extracted with ethanol (SPE) and hot water (SPW), and then safflower yogurt was prepared by adding 0%-1.0% of those extracts to plain yogurt. With an increase in the fermentation duration, the pH of SPE and SPW yogurt samples was decreased, whereas titratable acidity and microbial counts were increased. The concentration of total polyphenols and total flavonoids, the activity of antioxidants, and the inhibitory effect on reactive oxygen species (ROS) were higher in SPW yogurt than SPE yogurt. Furthermore, α-glucosidase and lipase activity inhibitory effects of SPW yogurt were higher than those of SPE yogurt. In particular, free radical-scavenging activities, ROS inhibitory effect, and α-glucosidase activity inhibitory effects were significantly increased in SPW yogurt in a dose-dependent manner. Overall, these results suggest that SP extract possesses antioxidant activities and that it can downregulate α-glucosidase and lipase activities. The SP extract may have potential benefits as a natural food additive for the development of functional yogurt.

자전거 도로 건설 같이 공공사업 성격이 강한 경우, 생활환경개선, 지역균형발전, 양호한 경관형성 등 다양한 도로기능 편익을 지니고 있는데 이들 항목은 기존 경제성 분석의 경우에서는 간과되는 측면이 있다. 이에 본 연구에서는 비시장재 가치를 평가하기 위하여 환경경제 분야에서 많이 적용하고 있는 조건부가치측정법(CVM : Contingent Valuation Method; 이하 CVM)을 이용하여, 실제로 자전거도로가 건설(해안선 자전거 일주 도로 건설의 예)됨으로써 발생하게 될 지역균형 발전 및 자전거 이용활성화를 고려하여, 시민들에게 직접 설문조사(전국 256가구)를 수행하고, CVM 방법론에 따른 지불의사액(Willing to Pay : WTP) 및 편익을 추정하였다. 그 결과 평균 WTP는 최소 2,114원 정도로 나타났다. 향후, 이러한 CVM 기법은 기존 경제성 분석을 활용한 편익 산출로는 한계가 있는 도로 건설 분야 중 도로교 건설에 따른 경관평가, 환경 개선에 따른 편익, 삶의 질 향상 등에 널리 활용될 수 있으리라 판단된다.

The use of yeast assist kefir fermentation, but also can cause food spoilage if uncontrolled. Hence, in this study, the microbial composition of an existing commercial kefir starter was modified to produce a functional starter, where Lactobacillus acidophilus KCNU and Lactobacillus brevis Bmb6 were used to replace yeast in the original starter to produce non-yeast kefir-like fermented milk. The functional starter containing L. acidophilus KCNU and L. brevis Bmb6 demonstrated excellent stability with 10¹⁰ CFU/g of total viable cells throughout the 12 weeks low-temperature storage. The newly developed functional starter also displayed a similar fermentation efficacy as the yeast-containing control starter, by completing the milk fermentation within 12 h, with a comparable total number of viable cells (10⁸ CFU/mL) in the final products, as in control. Sensory evaluation revealed that the functional starter-fermented milk highly resembled the flavor of the control kefir, with enhanced sourness. Furthermore, oral administration of functional starter-fermented milk significantly improved the disease activity index score by preventing drastic weight-loss and further deterioration of disease symptoms in DSS-induced mice. Altogether, L. acidophilus KCNU and L. brevis Bmb6 have successfully replaced yeast in a commercial starter pack to produce a kefir-like fermented milk beverage with additional health benefits. The outcome of this study provides an insight that the specific role of yeast in the fermentation process could be replaced with suitable probiotic candidates.

PURPOSE: Proprioceptive Neuromuscular Facilitation (PNF) has been shown to improve body function and activity/participation in people with functional dysfunctions. This study evaluates if active exercise using theraband in PNF pattern may induce similar benefits as exercise using manual PNF pattern performed by physiotherapists on promoting mobility, balance and fear of fall in community-dwelling elderly. METHODS: Twenty-three community-dwelling elderly with independent activities of daily living were recruited and randomly allocated into either PNF group - exercise in PNF pattern by trained physiotherapists or Theraband-PNF (T-PNF) group - exercise using theraband in PNF pattern, for an hour, twice weekly for 4 weeks. Functional outcomes such as Timed Up and Go test, Elderly Mobility Scale, Berg balance scale, functional reach and subjective measures including fear of fall (FOF) scale, bodily pain in visual analogue scale were measured pre and post-program. RESULTS: Twenty-one participants completed the program. PNF group demonstrated significant within-group improvements in all subjective measures and objective measures. Similar within-group improvements were demonstrated in all outcome measures except FOFS in T-PNF group. However, no between-group differences were found in any of the outcome measures. CONCLUSION: Comparable improvements in functional outcomes in community dwelling elderly were demonstrated in both groups. As manual PNF exercise traditionally need clinicians' contact and feedback on patient which limit the training to be carried out extensively in community setting. The current findings suggest that exercise using theraband in PNF pattern is feasible to be adopted as self-practice exercise for community-dwelling elderly to induce beneficial effects on functional outcomes.

PURPOSE: This study aimed to determine the effects of task-oriented treadmill training on the gait and balance ability and functional activity in 20 patients with subacute stroke. METHODS: The study subjects were twenty stroke patients, ten randomly placed in the experimental group and ten in the control group. Both the experimental and control groups received 30 minutes of traditional physical therapy and an additional 15 minutes of functional electrical stimulation therapy. The experimental group was given task-oriented treadmill training, while the control group received general treadmill training. Each session lasted for 25 minutes, three times a week, over four weeks, totaling 12 sessions. RESULTS: Both groups showed statistically significant differences in the 10-metre walk test (10MWT), timed up and go test (TUG), Fugl-Meyer Assessment (FMA), and Modified Barthel index (MBI). However, statistically significant differences in the Functional Ambulation Categories (FAC) and Berg Balance Scale (BBS) were seen only in the experimental group. There were statistically significant differences in the between-group differences value comparisons in the 10MWT, BBS, TUG, FMA, and MBI. CONCLUSION: Task-oriented treadmill training positively impacts gait, balance, and daily function in subacute stroke patients. This study highlights the benefits of training on unstable surfaces and offers valuable insights for stroke rehabilitation and gait training.

This project addresses the product identification and design application of corrugated products for kinetic architectural applications. Initially, an architectural approach to product identification was carried out with the end goal of demonstrating application design principles of numerous novel architectural examples from the forest products industry. A design and prototyping stage followed demonstrating such application design principles and functional analysis on various novel architectural examples. The results of coupling product identification with proven application advantages will be of potential value not only to architecture but also to other designers in the arts and sciences. The general motivation for the research arises out of a growing interest corrugated and paper products to be ideally suited for various architectural applications for their unparallel environmental benefits. Applications in architecture that use fewer resources and that adapt efficiently to complex and changing conditions are particularly relevant for an industry (architecture) that is increasingly aware of its environmental responsibilities. Corrugated and paper products are highly under-utilized by the building industry as design choice material for both interior and exterior applications. An increased awareness of the benefits of corrugated and paper products coupled with a process of designing for the total use and reuse will prove to be a valuable means by which issues of energy efficiency and environmental quality of buildings could be enhanced to be more efficient, affordable, and therefore reach a broader audience of users.
