金炯祐,徐城鐸,全燾基 中央醫學社 1973 中央醫學 Vol.25 No.2

In order to know the current status of sensitivity of urinary and enteric pathogens including pathogenic vibrios to some antimicrobial agents of current use, the sensitivity of these organisms isolated in recent years from. pathological sources except most of Vibrio parahaemolyticus which were isolated from marine sources) was studied by the agar plate dilution method. The antimicrobial agents tested were kanamycin (Kan), gentamicin (Gen), penicillin G (Pen), ampicillin (Amp), neomycin (Neo), oxytetracycline (0-Tet), minocycline (Min), doxycycline (Dox), furilin (Fur), streptomycin (Str), chloramphenicol (Chl), erythromycin (Ery), colistin (Col), carbenicillin (Carb), polymyxin .B (PxB), trimethoprim (TMP), sulfamethoxazole (SMX) and the mixture of TMP-SMX. Urinary isolates was classified into two major species, staphylococci and Escherichia coli, and the others were enteric gram negative bacilli and gram positive. cocci. These organisms were sensitive to Gen but resistant to most of antimicrobial agents of current use. They were especially resistant to Str, Kan, Pen, Amp, Chlr O-Tet, TMP-SMX and Col. Salmonella was strongly sensitive to Kan and moderately sensitive to drugs other than TMP-SMX, Ery and Col. Shigella was strongly sensitive to Kan, Gen and Amp, but highly resistant to Stir,

해외골프여행객의 소비가치, 소비만족, 소비행동의 관계

김형우,최윤근,서재열 한국골프학회 2022 골프연구 Vol.16 No.4

[Purpose] The purpose of this study was to identify the structural relationship between the consumption value, consumption satisfaction, and consumption behavior of overseas golf travelers, to identify the consumption behavior of golf travelers, and to suggest a direction for improving the conditions of domestic golf courses. [Method] To this end, an online survey was conducted on the golf travel community with a population of people who recently traveled to Japan. A total of 354 people participated in the survey, but 220 people who responded that they had been on a golf trip were used for the final analysis to obtain the following results. [Result] First, the consumption value of overseas golf travelers had a positive effect on consumption satisfaction. Second, the consumption value of overseas golf travelers had a positive effect on consumption behavior. Third, consumption satisfaction had a positive effect on consumption behavior. [Conclusion] Due to the easing of COVID-19, more and more golfers are turning to overseas golf markets. As they seem to be turning overseas to find something more reasonable and new, it is time for domestic golf courses to change to suit their consumption value. [목적] 이 연구는 해외골프여행객의 소비가치, 소비만족, 소비행동의 구조적 관계를 파악하여 골프여행객들의 소비행동을 파악하여 국내 골프장의 여건 개선에 대한 방향성을 제시하는데 목적을 두고 연구하였다. [방법] 이를 위해 골프여행전문 커뮤니티에 최근 일본으로 골프여행을 다녀온 사람을 모집단으로 온라인 설문조사를 실시하였다. 총 354명이 설문조사에 참여하였으나 골프여행을 다녀온 것으로 응답한 220명을 최종분석에 사용하여 다음의 결과를 얻었다. [결과] 첫째, 해외골프여행객의 소비가치는 소비만족에 정적영향을 미쳤다. 둘째, 해외골프여행객의 소비가치는 소비행동에 정적영향을 미쳤다. 셋째, 소비만족은 소비행동에 정적영향을 미쳤다. [결론] 코로나19의 완화로 인해 해외 골프시장으로 발길을 돌리는 골퍼들이 많아지고 있다. 이들은 보다 합리적이고 새로운 것을 찾아 해외로 발길을 돌리고 있는 것으로 보이는 만큼 국내 골프장에서는 이들의 소비가치에 맞게 변화되어야 할 시점이라 판단된다.

Vitamin C Up-regulates Expression of CD80, CD86 and MHC Class II on Dendritic Cell Line, DC-1 Via the Activation of p38 MAPK

김형우,강재승,이왕재,조수인,배세연,김혜민,김예진,황영일 대한면역학회 2012 Immune Network Vol.12 No.6

Vitamin C is an essential water-soluble nutrient which primarily exerts its effect on host defense mechanisms and immune homeostasis, but the mechanism related to immune- potentiation is poorly understood. Since dendritic cells (DCs) are known as a potent antigen presenting cell (APC) that could enhance the antigen specific immune responses, we investigate the effects of vitamin C on activation of DCs and its related mechanism by using dendritic cell lines, DC-1. First, we found that there was no damage on DC-1 by 2.5 mM of vitamin C. In the presence of vitamin C, the expression of CD80,CD86, and MHC molecules was increased, but it was decreased by the pre-treatment of SB203580, p38 MAPK-specific inhibitor. We confirmed the phosphorylation of p38MAPK was increased by the treatment of vitamin C. Taken together, these results suggest that vitamin C could enhance the activity of dendritic cells via the up-regulation of the expression of CD80, CD86, and MHC molecules and the activation of p38 MAPK is related to this process.

Recent developments in microfluidic devices based on microelectromechanical systems (MEMS) technique find many practical applications, which include electronic chip cooling devices, power MEMS devices, micro sensors, and bio-medical devices among others. For the design of such micro devices, flows characteristics inside a microchannel have to be clarified which exhibit somewhat different characteristics compared to conventional flows in a macrochannel. In the present study microchannels of various hydraulic diameters are fabricated on a silicon wafer to study the pressure drop characteristics. The effect of abrupt contraction and expansion is also studied. It is found from the results that the friction factor in a straight microchannel is about 15% higher than that in a conventional macrochannel, and the loss coefficients in abrupt expansion and contraction are about 10% higher than that obtained through conventional flow analysis.

본 논문은 해저 연약지반 위를 주행하는 시험집광기의 동적거동 해석을 다루고 있다. 시험집광기는 단괴채집장치, 무한궤도, 단괴파쇄기, 샤시프레임, 전기 전자 시스템으로 구성되어 있다. 시험집광기의 공기 중 무게는 8,600 kg이며, 수중에서의 시험집광기의 평균접지압은 6.0 kPa이다. 상용해석 프로그램인 RecurDyn-LM과 Visual Fortran 90을 이용하여 시험집광기의 동적거동 해석 모델 및 유체저항력 모델을 구축하였다. 상용해석 프로그램(RecurDyn-LM)에서 제공되는 사용자 정의 서브루틴을 이용하여 연약지반역학 모델 및 유체저항력 모델을 구축하였으며, 이를 통하여 해저 시험집광기의 동적거동 해석을 수행하였다. 궤도속도, 지반조건, 항력계수 및 추가질량 계수의 변화에 따른 시험집광기의 동적응답을 분석하였다. We conducted a dynamic analysis of an underwater test collector, which operates on extremely soft soil of deep-seafloor. The underwater test collector consists of nodule pick-up device, vehicle tracks, nodule crusher, loading frame and electric-electronic system. The weight of underwater test collector is about 8600 kg. The average normal pressure, that the underwater test collector supports, is about 6.0 kPa. The dynamic analysis model of underwater test collector is developed using commercial software RecurDyn-LM and Visual Fortran 90. A terramechanics model of extremely soft soil is implemented to the software based on user-written subroutine and applied to the dynamic analysis of the underwater test collector model. The dynamic responses of test collector are studied with respect to track velocities, terrain conditions, and coefficients of added mass and drag.
