고경진,정재관 한국화학공학회 1985 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.23 No.5

고-액계형의 반응은 고체입자의 세공을 통한 입자확산과 외부고체 입자의 표면에 대한 경막확산의 저항이 존재하여 복잡하다. 그러므로 경막 및 입자확산의 저항을 최소화하기 위한 조작상태를 정립할 필요가 있다. 확산으로 인한 저항을 제거함으로써 반응속도를 분석할 수 있다. 미분층 반응기를 사용하여 활성탄에 의한 올소인산 제거의 반응기구를 구명하는 반응속도식의 결과는 다음과 같다. pH 4.0 : r=0.0240 C_e - 0.0379 C_i^(0.28) q_e^(0.80) pH 8.0 : r=0.0179 C_e - 0.0361 C_i^(0.28) q_e^(0.80) pH 12.0 : r=0.00619 C_e - 0.0136 C_i^(0.28) q_e^(0.80) 본 반응속도식에서 pH 4.0의 제거속도가 pH 8.0 및 12.0보다 빠름을 알 수 있다. 그리고 올소인산 제거의 반응속도식이 평형에 도달하면 Freundlich흡착평형 등온선에 점근함을 알 수 있다. pH변화에 따른 활성탄에 의한 올소인산의 최대흡착은 pH 4.5∼7.0에서 일어난다. The liquid-solid type reaction encountered in this study is usually complicated by the presence of resistances as a result of film diffusion across the external solid surface and particle diffusion through the pores of solid. Therefore, it became necessary to establish the operating conditions that minimized the influence of film and particle diffusion. This investigation was an attempt to eliminate these diffusional effects and determine the kinetics of the removal of orthophosphates from the aqueous solutions by activated carbon using a differential bed reactor approach. The reaction kinetics studied in this experiment may be summarized as follows: r=0.0240 C_e - 0.0379 C^(0.28)_i q_e^(0.80) at pH 4.0 r=0.0179 C_e - 0.0361 C^(0.28)_i q_e^(0.80) at pH 8.0 r=0.00619 C_e - 0.0136 C^(0.28)_i q_e^(0.80) at pH 12.0 A comparison of these equations indicates that the reaction kinetics at pH 4.0 is much faster as compared to those at pH 8.0 and 12.0. The equilibrium adsorption studies support the existence of this adsorption isotherm which fits the empirical Freundlich isotherm, comparatively. For activated carbon, maximum orthophosphates adsorption occured at pH 4.5 - 7.0 with decreasing amounts of adsorption at lower and higher pH.

Objectives: To investigate the correlation of anxiety or depression mood with physical stress of 59 participants (29 who complained of chronic headache and 30 who did not complain of headache) using a questionnaire on chronic headache symptoms, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), and Heart Rate Variability (HRV). Methods: In this study, medical records of 59 participants (29 who complained of chronic headache and 30 who did not complain of headache) who completed the BAI, BDI, HRV, and Questionnaire for chronic headache symptoms were evaluated. All data were analyzed using SPSS (Statistical Package for the Social Sciences, Version 26.0). Descriptive Analysis, Mann-Whitney U test, Chi square test (Fisher’s exact test), and Pearson correlation coefficient were used for data analysis. Results: 1. The chronic headache group had significantly lower SDNN, RMSSD, TP, LF, and HF values on HRV than the general control group. 2. As BAI and BDI scores of the chronic headache group increased, the overall HRV value tended to decrease, indicating a deep association. 3. There was a negative association between BDI and HRV values in the chronic headache group, although such association was not statistically significant. Conclusions: BDI can be negatively correlated with HRV (SDNN, RMSSD, TP, LF, HF) in chronic headache patients.

고경진,박상현,장원용 한국체육정책학회 2019 한국체육정책학회지 Vol.17 No.2

The purpose of this study was to redefine growth stage of sports companies and establish essential support strategies according to the growth stage by using theoretical review, expert interview, and businesses survey. The results of this study were as follows. First, average annual growth rate was used to distinguish between growth stages because most sports companies were small and petty. Based on this criteria, growth stages of sports companies divided into 'start-up/low growing period', 'growing period', 'high-growing period', and 'second leap period'. Second, special financial support and legal support was needed in 'start-up/low growing period', consulting related to entrepreneurship education and capacity building was needed in 'growing period', supports about overseas certification system and patent acquisition was needed in 'high-growing period, and supports regarding re-education and offing diverse source of information was needed in 'second leap period'. Third, The expansion of the loan business, participation in overseas exhibitions, and basic consulting support were shown as common support strategies.

고경진,마윤성,신진호 한국체육정책학회 2018 한국체육정책학회지 Vol.16 No.2

The purpose of this study is to improve the current policy financial support systems in sport industry and expand the application scope of the current loan support system. To achieve this purpose, the current status and deficiencies of policy financial support systems related to sports industry were diagnosed and domestic and foreign policy finance cases were analyzed. On the basis of case study, applicable alternatives to improve the current policy finance in domestic sport industry are derived. Method of this study included literature reviews, analysis of domestic and foreign policy finance and expert consultation. The result of this study are as follows. First, to diversify the current policy finance of sport industry, it is required to consider ways to diversify and timely support loan types according to the corporation life cycle. Second, financial scheme about saving interest cost partially from financing loan is recommended. Third, It is also suggested that financial support utilizing credit guarantee or technology guarantee systems is expected to activate the management of sport related corporations, because most of domestic sport corporations have insufficient collateral that could be provided to financial institutions when applying for commercial loan.
