전용진 혜전대학 1997 論文集 Vol.15 No.-

철용기화성 방청제로 dialkylamine 4-nitrobenzoates 화합물을 산ㆍ염기 반응으로 합성하였다. 부식억제 효과를 시험하기 위해 lM Na₂SO₄ 용액에 합성한 방청제를 1%(w/v) 농도로 용해시켜 potentiostatic method로 분극실험 결과, diethylamine 4-nitrobenzoate용액의 부동태화 전류밀도 (i_(p))는 4.78㎃/㎠로 얻었다. 첨가제 효과로 dialkylamine 4-nitrobenzoates와 (NA₄)₂CO₃, NaHCO₃의 최적 혼합비율은 4 : 6, 5 : 5이었으며 이 때 부동태화 전류밀도(i_(p))는 0.26, 0.85㎃/㎠로 최소값을 나타냈다. 철용 방청액의 최적 혼합물을 KS A-2111에 따라 시험결과 우수하였다. Dialkylamine 4-nitrobenzoates for vapor corrsion inhibitior were synthesized with dialkylamines and 4-nitrobenzoic acid. Corrosion inhibition of synthetic compounds and additives against ferrous metal were investigated by potentionstatic method [1%(w/v) corrosion inhibitor in 1M Na₂So₄ solution]. The passivating current density(i_(p)) of diethylamine 4-nitrobenzoate was shown 4.78㎃/㎠. Optimum ratio of diethylamine 4-nitrobenzoate with additive (NH₄)₂CO₃ and NaHCO₃ were 4 : 6 and 5 : 5(V/V), and passivating current density(i_(p)) of mixtures were shown 0.26, 0.85㎃/㎠ respectively. Test of KS A-2111, optimum fomulated anticorrosive solution containing diethylamine 4-nitrobenzoate was shown good results.

전용진,John, Yong-Jean 한국디지털정책학회 2021 디지털융복합연구 Vol.19 No.7

비대면 금융채널을 이용하는 고객증가와 모바일뱅킹의 보안에 대한 고객의 관심과 우려감이 증대함에 따라 본 논문은 모바일뱅킹 보안과 정보 신뢰가 사용자 태도와 사용의지에 얼마나 어떻게 영향을 미치는가 확인하려고 한다. 논문의 목적은 첫째, 모바일뱅킹 사용자의 보안과 정보신뢰에 대한 인지 정도를 확인한다. 둘째 모바일뱅킹 보안과 정보신뢰가 모바일뱅킹 사용 태도에 영향을 미치는 주요 요인을 확인하고, 그 영향의 정도를 측정한다. 설문조사는 2020년 11월부터 2021년 2월까지 18세 이상 성인남여를 대상으로 실시하였으며, 요인분석후 KMO, Bartlett's test, Crombach Alpha를 확인하여 타당성과 신뢰성 검증 후 회귀분석을 하였다. 분석결과 보안 및 신뢰와 모바일뱅킹 태도에서는 정보보호 및 안전성, 대고객 신용, 정보의 신뢰가 상품정보만족에 영향을 주었으며, 편의성 인지에는 외부공격 대응능력, 대고객 신용, 정보보호 및 안전성이 영향을 미치고 있다. 보안 및 신뢰와 모바일뱅킹 고객의 향후 사용의지에서는 은행의 정보보호 및 안전성과 대고객 신용이 고객의 금융상품거래의지에 영향을 미치고 있으며, 모바일 앱을 통한 금융업무처리 의지에는 외부공격 대응능력과 대고객 신용이 영향을 미치고 있는 것으로 나타났다. 본 논문은 각 금융사가 오픈뱅킹으로 인해 이동이 자유로와진 고객을 확보하기 위한 경쟁속에서 모바일뱅킹의 보안과 신뢰성 측면에서 모바일뱅킹 앱 개선방향에 시사점을 줄 것으로 기대한다. The pandemic age came to us after the COVID19 broke out in the early of 2020, which resulted in many changes in our everyday life. One of the changes is non-contact transactions in economic activities, especially contact-free financial transactions are ever-increasing activities in the pandemic age. In non-contact financial transactions, security and trust are important issues that users are concerned about the most. So the paper examines how security and trust have effects on the attitudes of bank customers who use mobile banking applications on their smartphones. The study conducted factor ananlysis to extract research constructs using survey data gathered during Nobember of 2020 through February of 2021 across the nation. After extracting the constructs, the study checked validity, sampling adequacy, and internal reliability with KMO, Bartlett's test, and Crombach Alpha respectively. To make sure the purpose of the study, I do regression analysis. All factors of attitude had impacts on willingness on both of transactions and purchasing financial products. The results could give guidelines banks which want to attract more customers in open-banking environment through ever-more secure and trusty mobile banking application.

전용진,심정자 한국동물분류학회 2008 Animal Systematics, Evolution and Diversity Vol.24 No.2

Two species of the family Chalinidae, Haliclona (Gellius) tubulensis n. sp. and Haliclona (Gellius) marismedi were collected from Hongdo Island and Gageodo Island, Korea during 2004-2007. H. (G.) tubulensis n. sp. is closely related to H. (G.) coreana in type of spicules and growth form. But it is different in size of toxas and oscules. Toxa of H. (G.) tubulensis n. sp. is one type and its oscules are tuberculated. The toxa of H. (G.) coreana is two types and lacks projections. The overall shape and spiculation of H. (G.) marismedi are nearly identical with specimens described by Pulitzer-Finali (1977).

A New Species of the Genus Penares (Demospongiae:Astrophorida: Ancorinidae) from Korea

전용진,심정자 한국동물분류학회 2009 Animal Systematics, Evolution and Diversity Vol.25 No.2

A new marine sponge in the family Ancorinidae, Penares hongdoensis n. sp. was collected from Hongdo Island, Korea by SCUBA diving in 2004. P. hongdoensis n. sp. is closely related to P. cortius de Laubenfels, 1930 in their spicules. However, they differ in kind and size of spicules and growth form. The dichotriaene rhabds of new species are larger than that of P. cortius. And the new species has oxyaster, but P. cortius has oxyspheraster. Although the growth forms of both species are irregular massive, this new species shows conspicuous long projection toward upper part.

키네시오 테이핑 적용이 전방머리자세가 있는 사람들의 머리척추각도와 균형능력에 미치는 영향

전용진,김경모 한국컴퓨터정보학회 2020 韓國컴퓨터情報學會論文誌 Vol.25 No.8

Forward head posture is one of the most recognized types of poor head and neck alignment. Poor head and neck alignment posture is a major contributor to compromised balance and neck pain, due to abnormal joint position sense and proprioception. Kinesio taping is an intervention method used clinically for the management of pain. Kinesio taping may produce its effects through pain reduction, stimulation of blood circulation, induction of muscle relaxation which provides correction of joint position, and providing stability to the muscles and joints without limiting the range of motion. Many studies have proved that kinesio taping has positive effects on the reduction of pain and improves alignment, on the other hand, some studies have not found. Kinesio taping may provide immediate pain relief and improved alignment following the application, but there is insufficient evidence to support sustained relief beyond that time and they recommended future studies to examine the benefits of kinesio taping as this would have a greater value in clinical practice. Therefore, this study is to investigate the effects of kinesio taping on the alignment of head posture and dynamic balance ability in people with forward head posture. 전방머리자세는 머리와 목의 잘못된 자세 정렬 중 하나로 비정상적인 관절 위치감각과 고유수용성 감각손상으로 인해 목의 통증과 균형 손상까지 발생시키는 주요 원인으로 알려져 있다. 키네시오 테이핑은 통증관리를 위해 사용되는 임상적인 중재방법으로 통증감소, 혈액순환 촉진, 근육이완을 유도하여 관절 위치 교정 및 근육과 관절에 안정성을 제공하는 효과를 가지고 있다. 이전의 많은 연구에서 키네시오 테이핑을 활용하여 목 통증감소와 목의 정렬에 긍정적인 효과가 있음을 입증하였지만 일부 연구에서는 통증 완화의 효과를 입증하지 못한 부분도 있다. 키네시오테이핑 적용 후 즉각적인 통증완화 및 정렬 개선에 효과를 보이긴 하지만 적용이후 효과의 지속에 대해서는 증거가 충분하지 않고 임상적으로 더 큰 가치를 보이기 위해서는 키네시오 테이핑의장점에 대해서 추가적인 연구를 권장하였다[1]. 따라서 본 연구는 앞머리 자세를 가진 사람에서키네시오 테이핑이 머리 자세의 정렬과 동적 균형 능력에 미치는 영향을 조사하고자 한다.
