정충경,부진효,배인섭,S. H. Jeong,S.-J. Cho,Y.-H. Song 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.3

We have deposited titanium dioxide (TiO2) thin films on glass using a single molecular precursor such as titanium (IV) iso-propoxide (Ti[OCH(CH3)2] 4, 97 %) by sol-gel process. In order to elevate photocatalytic activity of the as-grown TiO2 films, argon and oxygen plasmas ignited by microwave (MW) discharge at 300 W under vacuum condition were also used within 5 min. at room temperature. Photocatalytic activity was evaluated by the measurements of the contact angle, FT-IR, XPS, and AFM analysis. In this work, the effect of the plasma on the improvement of hydrophilic property of TiO2 photocatalyst has mainly been investigated. Superhydrophilic property and smooth surface morphology appeared in the UV light irradiation with O2 plasma treatment more than Argon plasma treatment. Based on this work, we confirmed that the oxygen MW plasma treatment method was very reliable method for the synthesis of TiO2 thin films with high catalytic performance.

정충경,부진효,배인섭,S.-H. Jeong,W. S. Choi 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.3

We have deposited SiOxNy thin films on both Si(100) and glass substrates by using a tetraethyl orthosilicate (TEOS) single precursor at nitrogen flow rates of 0 100 sccm by using a radiofrequency Plasma Enhanced Chemical Vapor Deposition (PECVD) method. The film growth orientation and microstructural characteristics were analyzed by scanning electron microscopy (SEM) and atomic force microscopy (AFM). Deposition at higher nitrogen flow rates results in finer clusters with smaller grain sizes. Moreover, we used UV/Vis and FT-IR spectroscopy and ellipsometry to investigate the optical properties for various nitrogen flow ratios. As-deposited SiO2 films showed an amorphous structure, but samples annealed in an O2 ambient at 900 C showed increased crystallinity. Also, the leakage current densities of the SiO2 and the SiOxNy films annealed at 900 C in an O2 ambient were about 4.0 × 10.8 and 1.5 × 10.7 A/cm2.

운동생리학 : 태권도선수의 수준별 체조성과 심폐기능 특성 비교분석

조충경(ChungKyungJo),김기봉(KiBongKim) 한국체육학회 2001 한국체육학회지 Vol.40 No.2

본 연구는 태권도의 남자일반우수선수와 비우수선수 및 고교우수선수들 중 각각 15명씩 총 45명을 대상으로 체조성과 심폐기능 요인의 특성을 비교분석하여 태권도 경기력에 영향을 미치는 요인을 구명하여 태권도 선수의 신인발굴을 위한 기준설정과 우수선수의 운동처방 프로그램 작성을 위한 합리적이고 과학적인 기초자료를 제공하기 위하여 실시하였으며, 그 결과를 비교 분석한 결론은 다음과 같다.1. 체조성은 제지방체중이 세 집단간에 유의한 차이가 있었고, 우수집단은 제지방체중에서 다른 집단보다 유의하게 높았다.2. 심폐기능은 안정시 심박수, 최대 심박수, 최대산소소비량 및 트레드밀 주행시간이 세 집단 간에 유의한 차이가 있었고, 우수선수집단은 최대심박수, 최대산소소비량 및 트레드밀 주행시간에서 다른 집단보다 유의하게 높았다.본 연구에 이어 앞으로 남·여 국가 대표급 선수와 고교우수선수 및 일반 수련자들과의 다각적인 요인에 대한 수준의 차이를 비교 분석하는 연구와 아울러, 각 체급별로 세분화하고 공격형과 방어형 등 선수의 경기유형에 따른 종합적인 연구가 필요하다. It is convinced that there are many body compositions and cardiopulmonary functions involved in performing “Taekwondo” efficiently and structure of these abilities underlying taekwondo performance will be changed with the consequence of training.The purposes of this study were to analyze the contributions of body composition and cardiopulmonary function underlying athletic performance in highly trained taekwondo athletes and to offer the basic scientific informations for the new talent selection and exercise prescription programs for training the excellent taekwondo athletes.The subjects participated for this study were 45 taekwondo athletes who were classified into three groups by the competitive levels; 15 adult excellent athletes, 15 adult good athletes and 15 high school excellent athletes.The statistical techniques utilized in this study was; ANOVA.Tukey test was used in post-hoc analysis.For all tests, alpha was set at .05 initially in significance.The findings of this study were as follows;1. There was significant differences in lean body mass of body composition among three groups and lean body mass was significantly higher in adult excellent athletes than those of two other groups.2. There were significant differences in resting heart rate, maximal heart rate, maximal oxygen consumption and treadmill running time of cardiopulmonary functions among three groups and maximal heart rate, maximal oxygen consumption and treadmill running time were significantly higher in adult excellent athletes than those of two other groups.

Recently, font and visual culture was changed in accordance with supply computer and the trend of experimental typography and replace uniform use of existing font by experimental typography and remarkably Calligraphy's use. It devise visual culture development through the new and artistic Calligraphy expression that create formative element with imply specific character involve the culture of the times Calligraphy's expression. In a restricted sense, Calligraphy is kallos(=beauty)+graphy. on the other hand Calligraphy is beautiful Calligraphy style which have the one and only of autograph. And Calligraphy style have unlimited expressional function. As different country, different character and expression of Calligraphy, in the meaning of Calligraphy is seo-ye(calligraphy) in the East, on the other hand that is beautiful handwriting which can trace the origin back to the man's speech function period in the West. But this study find out Calligraphy's identity of unique genre. And this expression is recognize Calligraphy to be unique visual language in nowaday's visual culture lead up to expression letter's role. And study calligraphy character and expression which iconography (letter that pass out of mind) with unlimited power of expression and free experimentalism.

As substance abuse of adolescents becomes severe day by day as a social problem, the authors feel the necessity of adolescent drug addiction screening test. Questionaire composed of 60 items of Substance Associated Problems Scale(SAPS) of J. Westermeyer and 12 items of modified NAST(M-NAST) was applied to 72 patients with substance abuse or dependence, and 82 controls. The data were analyzed by canonical discriminant analysis using Proc stepdisc, and the 20 items with discriminant power were selected.

COVID-19 사태로 인한 항공사 승무원의 정서적 불안정성이 고용불안에 미치는 영향

조충경(Joe, Choonggyeong),양위주(Yhang, Wiijoo) 대한관광경영학회 2021 觀光硏究 Vol.36 No.7

본 연구의 목적은 COVID-19 사태가 항공사 승무원의 정서적 불안정성이 어떻게 나타나는지 검증한 뒤, 정서적 불안정성과 고용불안에 미치는 영향에 관한 연구이다. 이러한 연구목적을 달성하기 위해 Oliver & Simons(2004)의 ALS(Affective Lability Scales)를 적용하였다. 연구결과에 이하면, 정서적 불안정성은 불안/우울증 , 분노 , 우울증/감소 등 3개 요인으로 구분되었으며, 항공사 승무원의 정서적 불안정성과 고용불안과의 인과관계에서 불안/우울증 과 우울증/우울증 은 주요 변수로 나타났지만, 분노 요인은 영향을 미치지 않는 것으로 나타났다. 본 연구는 COVID-19 사태와 같은 팬데믹 확산은 일반대중의 정서적 불안정성을 야기시키며, 관광산업 가운데 항공산업에도 어려움을 미치고 있지만, 항공산업에 미치는 영향에 대한 연구가 부족한 것에 착안하였다. 연구결과에 따르면, 그 항공사와 임원은 직원들이 과도한 고용불안을 느끼지 않도록 노력하고 정서적 안정 프로그램, 상담, 교육 등 지속적인 관리를 수행해야 함을 알 수 있다. 본 연구결과는 항공사 직원을 대상으로 한 경험적 연구이므로 향후 항공산업의 종사하는 승무원의 효과적인 인적자원관리에 기여할 것이다. The purpose of this study is to verify how the airline employees affective lability appears due to the outbreak of COVID-19, to confirm the relationship between the affective lability and employment insecurity. Oliver & Simons(2004)’ ALS(Affective Lability Scales) was applied to this research and then anxiety/depression , anger , and depression/elation was selected to check affective lability, and then the relationship to employment insecurity was verified. The results of this study suggested that the leading variables affecting the employment insecurity of airline employees were anxiety/depressed and depressed/elations , but the anger factor did not affect it. This study is based on the situation in which the public’s affective labilities and many difficulties on industries were due to COVID-19 outbreak. But little research has been done on airline industry caused by the pandemic spread. Therefore, airlines and executives should try to ensure that their employees do not feel excessive employment insecurity and to carry out continuous management such as affective stability programs, counseling, educations, etc. This study will contribute to an effective human resource management in the aviation industry by conducting an empirical analysis for airline employees.
