Through these research results, I would like to present some implications for promoting and revitalizing local food sales in Daejeon and establishing a local food system. First, in terms of local food direct stores, when establishing a local food store, location conditions should be considered. If the location cannot be changed, the quality of agricultural products should be improved to improve consumer satisfaction and purchase intention so that consumers can directly feel the value of the product. Second, efforts at the local government level are needed to improve the stability of local food. There are still many consumers who are not properly aware of local food. It is necessary to improve consumers' interest in the value of local food by providing education including social and environmental information on the production and distribution process of local food. Third, policy efforts on local food are needed. It is necessary to introduce and reorganize the local food certification system to emphasize the stability of local food to consumers and form trust. Finally, for the continuous development of local food, research on the satisfaction and purchase intention of local food consumers must be continuously conducted.

Purpose: According to various medical publications, it is believed that epinephrine should not be injected in fingers. However numerous articles show the successful use of local anesthetic with epinephrine in the digits. Epinephrine-mixed lidocaine solution enables to maintain a bloodless field for operation and provides long duration of local anesthesia when patient was wide awake. Methods: From May 2009 to December 2009, ten patients underwent flexor tendon reconstruction with local anesthesia using epinephrine. No tourniquet was necessary. Before operation, all patients were injected with local anesthetics using 1% lidocaine 20 mL and 0.1% epinephrine 0.1 mL. Results: There was no case of digital necrosis nor gangrene in the epinephrine injection. All 10 patients actively could move the finger through a full range of motion. All procedures were performed without sedation nor tourniquet and we could obtain a good vision of operative field and patients were comfortable. The patient make his or her fingers move through a full range of active motion before the skin is closed. Phentolamine was not required to reverse the vasoconstriction in any patients. Conclusion: The assertation that epinephrine should not be injected into the fingers is clearly no longer valid. The epinephrine injection allowed the authors to adjust flexor tendon surgery without risks associated with general anesthesia. It also enables to ensure longer anesthetic duration and bloodless operative field, and prevent post operative complications. In case of flexor tendon surgery, the use of epinephrine injection is recommended because of the advantages of local anesthesia.

In object analysis by image processing, finding lines plays a universal role. And these lines can be easily found by detecting ridges and valleys in digital gray scale images. In this paper, a new method of detecting ridges and valleys by using local min/max operations was presented. This method detects ridges and valleys of desired width by using erosion and dilation properties of local min/max operations, and requires no information of ridge or valley direction. Therefore the method is efficient and computationally simple in comparision with the conventional analytical method.

A digraph T is called a local tournament if for every vertex x of T, the set of in-neighbors as well as the set of out-neighbors of in-neighbors of x induce tournaments. Let x and y be two vertices of a 3-connected and arc-3-cyclic local tournament T with y x. We investigate the structure of T such that T contains no (x,y)-path of length k for some k with 3 k V(T) -1. Our result generalized those of [2] and [5] for tournaments.

Recently we performed video-assisted thoracoscopic[VAT] examination and bullectomy under local anesthesia. Of the 10 patients undergoing VAT examination under local anesthesia with primary spontaneous pneumothorax, 8 patients underwent VAT bullectomy under local anesthesia using endo-GIA; 7 patients discharged within 24 hours after operation; 1 patient had an air leak after operation, so chemical pleurodesis with doxycycline was performed and discharged postoperative day 3. There have been no recurrence to date[60-120 days after operation]. We think spontaneous pneumothorax can be treated on an out-patient basis.

This study was investigated for the local festival's educational impact. And take advantage of local festivals and educational effectiveness of the educational factors that affects, local festivals, depending on the type, application factors and intention to revisit whether there are differences in educational projects have identified the effect. So take advantage of the educational needs of local festivals for the purpose is to recognize that. To this end, 2010 Cheongdo persimmon festival's visitors were surveyed. How to analyze the descriptive statistics and factor analysis, reliability analysis, multiple regression analysis, ANOVA was used. The results of multiple regression analysis, community education of local festivals, discretionary activities, and agricultural education in educational projects in local festivals factor effects showed positive effects. The results of ANOVA, type programs and performances of the factors exhibition programs, experiential programs were no significant differences between groups. Of intention to revisit, "will revisit" and "I do not know", "will not visit" and "I do not know" and "will not visit" was no significant difference between the groups. These results, focusing on the needs of local festivals take advantage of the educational implications for the proposed recognition.

Purpose - This study examined the influence relationships between the impacts of tourism development, local attachment, and resident involvement and local residents' support and pro-environmental behavior intentions in Jeju Island. Design/methodology/approach - A questionnaire was distributed to the Jeju Island residents and 373 samples were used for the analysis. Findings - The results showed that the perceived positive impact of tourism development has a positive effect on local residents' support, while the negative impact has a negative effect. Local attachment has no significant effect on local residents' support, while local involvement positively affects local residents' support. The positive impact of tourism development has a negative effect on pro-environmental behavior intention, while the perceived negative impact has a positive effect. Finally, when analyzing the relationship between local attachment, local involvement, and local support for eco-friendly behavior intention, it was found that they all have a positive effect. Research implications or Originality - Theoretical and managerial implications and suggestions for future research are discussed.

최근 들어 홍수피해를 유발하는 것은 강우의 총량이기보다 기후 변화에 따라 발생하는 국지성 집중호우라 할 수 있다. 이러한 국지성 집중호우를 고려한 강우강도 개념을 도입하면서 배수펌프장 등과 같은 국내 배수시설 설계가 최근 개선되고 있으나, 교량용 배수시설 관련하여 별다른 개정이 없는 실정이다. 또한, 미연방도로국의(FHWA)의 배수설비 기준에 비하여 국내의 교량용 배수시설 기준은 합리적인 배수관 설계 방법을 제시하지 못하고 있다. 이러한 문제점을 해결하기 위해, 국지성 집중호우를 고려한 확률강우강도식을 사용하여 합리적인 교량용 배수관경 설계 기준안을 본 논문에서 제시한다.

Repairing surgical defects of the nose is still challenging due to its tridimensional shape and its aesthetic concern. Difficulty in reconstructing nasal subunits lies in their contour, skin texture and limited availability of adjacent skin. For lower nasal dorsum and supra-tip regions, we design a new combined local flap as existing local flaps may give disappointing results. This combination flap was performed on two patients for reconstruction of the lower nasal dorsum area after basal cell carcinoma excision. Size of the excision ranged from 20 to 25 mm diameter and safe margins were obtained. The defects were reconstructed with a local flap that combined a rotation nasal flank flap and a V-Y advancement nasolabial flap. Excision and reconstruction were performed in a one-stage surgery under intravenous sedation and local anesthesia. There were no postoperative complications and no flap loss occurred. Aesthetic and functional results after 6 months postoperatively were satisfying without modification of nasal shape. This flap is reliable and offers interesting functional and aesthetic outcomes. It can be considered as a new reconstruction alternative for supra-tip and lower nasal dorsum skin defects performed in a one-stage procedure under local anesthesia.

Objectives: The aim of this study was to describe a simple, convenient, and reliable new technique using local full-thickness skin graft (FTSG) for skin coverage of a donor-site defect of the radial forearm free flap (RFFF). Patients and Methods: Between April 2016 and April 2021, five patients with oral squamous cell carcinoma underwent mass resection combined with RFFF reconstruction. After RFFF harvesting, donor-site defects were restored by proportional local FTSG. Results: The donor-site defects ranged in size from 24 to 41.25 cm², with a mean of 33.05 cm². Good or acceptable esthetic outcomes were obtained in all five patients. There was no dehiscence, skin necrosis, wound infection, or severe scarring at the graft site through the end of the postoperative follow-up period, and no patient had any specific functional complaint. Conclusion: The proportional local FTSG showed promising results for skin coverage of the donor-site defect of the RFFF. This technique could decrease the need for skin grafts from other sites.
