Purpose: Microcirculation of diabetic patients is commonly comporomised, regardless of the condition of the macrocirculation. Therefore, direct tissue oxygenation measurement is recommended in determining tissue viability and predicting wound healing potential. This study was designed to determine cut-off value of the tissue oxygenation in predicting wound healing in diabetic foot patients. Methods: This study included 41 feet of 41 diabetic foot patients who were treated in the Diabetic Wound Center of author’s institution between January and June, 2009. Main inclusion criteria were type 1 or 2 diabetes and a foot ulcer (duration > 3 weeks) and ulcer area(from 1cm^2 to 4cm^2). Measurements of the area of diabetic foot ulcer were carried out before treatment. Transcutaneous oxygen pressure(TcpO_2) was measured at adjacent site of ulcer. The healing wound was defined as complete wound closure within 12 weeks. Results: Average diabetic foot ulcer areas with healing and nonhealing wounds were 2.67±0.76 and 2.59±0.75 cm2, respectively. There was no significant difference in the wound area between the groups. Average foot TcpO_2 in healing and nonhealing wounds were 68.56±23.07 and 30.98±16.66mmHg, respectively(p<0.01). The rate of healing wound increased as TcpO_2 increased. In particular, TcpO_2 lower than 40mmHg and higher than 40mmHg showed the most significant difference(wound healing rates of 25% and 71%, respectively). Conclusion: Based on the results of the study, the minimal TcpO_2 value thought to be required for adequate wound healing in diabetic wounds(cut-off value) is 40 mmHg.

Background: Post-transplant immunosuppression with calcineurin inhibitors (CNIs) is associated with kidney function impairment while mammalian target of rapamycin (mTOR) inhibitors, such as everolimus, can be used for its renal-sparing effects. In this study, we compared the efficacy and safety of everolimus with low dose tacrolimus (EVR+Low TAC) and conventional dose tacrolimus (TAC) in liver transplantation recipients. Methods: Medical records of recipients who received liver transplantation at Seoul National University Bundang Hospital from January 1st 2009 to December 31st 2018 were retrospectively reviewed. Cohort entry date was defined as the day everolimus was initiated and tacrolimus dosage was reduced. All patients were followed up for 1 year. Indicator of efficacy was the incidence of rejection and safety was evaluated by incidence of drug adverse events including renal function. Results: Among 118 patients, there were 40 patients (33.9%) in EVR+Low TAC group. Incidence of rejection, including both biopsy proven acute rejection and clinical rejection, was similar in two groups [7.5% (n=3) vs. 6.4% (n=5), p=1.000]. Renal dysfunction was less frequent in EVR+Low TAC [17.5% (n=7) vs. 35.9% (n=28), p=0.038]. However, incidence rates of dyslipidemia, oral ulcer were more frequent in EVR+Low TAC [45.0% (n=18) vs. 21.8% (n=17), p=0.009; 15.0% (n=6) vs. 1.3% (n=1), p=0.006]. Conclusions: In terms of prevention of rejection, EVR+Low TAC was as effective as TAC and had renal-sparing effect but was associated with increased risk of dyslipidemia and oral ulcer. This study demonstrates that EVR+Low TAC could be an alternative to liver transplant recipients with nephrotoxicity after administration of conventional dose tacrolimus.

정량적 지표가 쾌락적 소비를 정당화할 수 있는가?: 환경 가치를 나타내는 속성의 지표화 효과

장서윤,안희경,Hyun Sang Shin 한국소비문화학회 2022 소비문화연구 Vol.25 No.4

지표화 효과(Specification Effect)는 상품의 속성을 정량적으로 나타내는 지표(specification)가 소비자의 선택에 미치는 긍정적인 영향을 의미한다(Hsee et al., 2009). 소비자들은 대용치일 뿐인 지표에 의존하고, 본인들의 실제 경험보다 지표에 훨씬 큰 가중치를 두어 제품을 선택한다. 이는 소비자들이 제품을 선택할 때 자신의 선택을 정당화할 수 있는 근거를 찾으려고 하기 때문이다. 이때 정량적 지표는 자신의 선택을 정당화하기 좋은 근거가 될 수 있다. 본 연구는 선행연구에서 나타난 지표화 효과를 확장하였다. 첫째, 환경에 관한 가치가 정량적 지표로 표시되었을 때 지표화 효과가 나타나는지 알아보았다. 둘째, 환경가치를 나타내는 속성의 지표화 효과가 나타난다면, 그 효과가 소비 목표에 따라서 다르게 나타나는지 알아보았다. 실험 결과, 쾌락적 소비 목표 상황에서는 환경 가치 지표가 없을 때보다 있을 때, 친환경 제품에 대한 선호가 유의미하게 증가하였다. 하지만 실용적 소비 목표 상황에서는 환경 가치 지표의 유무에 따른 친환경 제품에 대한 선호 차이가 사라졌다. 본 연구는 지표화 효과가 환경 가치를 나타내는 속성에 대해서도 나타나고, 이 효과가 실용적 소비 목표가 아닌 쾌락적 소비 목표 상황에서만 나타났다는 것을 검증했다는 데에 의의가 있다. 또한 환경 가치 지표의 효과적인 적용을 위한 마케팅적 시사점을 제공한다.

In this paper, we use only a single 2D camera to measure the size change of objects moving in real time within a frame and convert them into coordinates that can be utilized for the control of the manipulator. This enables distance-value transformations that can be utilized for robot control without sensors and 3D depth cameras, and allows the construction of experimental devices for simulation.

The purpose of this study is to explore the effects of Acceptance and Commitment Therapy (ACT) on anger, problematic behavior, and self-esteem of adolescents in school maladjustment. A total of 120 adolescent students in an alternative school who lived in Chonbuk province completed the State-Trait Anger Expression Inventory-Korean Version (STAXI-K), Self-Esteem Scale while The Korean-Child Behavior Checklist (K-CBCL) was completed by alternative school teachers. Twenty-two adolescents selected by those scales were randomly assigned to include 11 adolescents in the ACT group and 11 in the control group. The ACT program was administered for 10 sessions. All participants completed State-Trait Anger Expression Inventory-Korean Version (STAXI-K), Korean-Child Behavior Checklist (K-CBCL), and Self-Esteem Scale at pre-test, post-test, and at 10-week follow-up. The results of this study were as follows: anger, problematic behavior of the therapy group showed a greater decrease, compared with those of the control group; self-esteem showed an increase in the therapy group. Finally, the implications and limitations of this study, as well as suggestions for future study were also discussed.

주거용부동산의 거주유형에 따른 베블런효과에 관한 연구: 과시소비성향을 중심으로

장서윤,하규수 한국벤처창업학회 2015 벤처창업연구 Vol.10 No.6

Recently, middle and low social class entered in the upper class for the specific reasons and joined reference group in order to present demonstration effect. This phenomenon was assumed the consumer’s desire for housing estate not from the leisure class. The superiority which feels belong to reference group, that was able to purchase high price product and the competence which can afford a high price goods are effective in housing estate. The study had been researched for Veblen effect according to residence estate. The partial least squares path modeling was used for Veblen effect affected by various psychological attributes, housing patterns and demographics for analysis. As a result, the conspicuous consumption from tenants was higher than residents, the social face sensitivity affected positively for self esteem and housing pattern, therefore, it caused conspicuous consumption. Moreover, we found conspicuous consumption had been increased followed by more spacious housing and higher income 최근 부유층 주거지에 특정 목적에 의한 중·저소득층이 진입, 준거집단에 합류하며 과시효과를 누리고 싶어 한다. 이 현상으로 주거용부동산에 대해 유한계급층이 아닌 일반 소비자들의 과시효과에 대한 욕구를 유추할 수 있다. 과시소비를 함으로써 고가의 상품을 구매할 수 있는 준거집단에 속한다는 우월함과 고가를 지불할 수 있는 능력을 통해 부를 전시하는 효과를 얻는다고 볼 때 자신의 사회경제적 능력을 보이기 위한 과시적 소비성향은 주거용부동산에도 영향을 미치리라고 예상된다. 본 연구에서는 주거부동산의 거주유형에 따른 베블런효과를 확인하고자 하였다. 이를 위해 다양한 심리적 특성, 주거특성, 인구사회학적 특성이 베블런효과에 미치는 영향을 PLS 경로모형을 이용하여 분석하였다. 분석결과 차가거주자가 자가거주자에 비해 과시소비성향이 높은 것으로 나타났으며, 체면민감성은 자아존중감과 주거유형에 정(+)의 영향을 미치며 이는 과시소비성향으로 이어진다. 또한 거주면적이 크고 소득수준이 높을수록 과시소비성향이 큰 것으로 확인되었다.
