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.

The purpose of this research is to look for achievement of sports industry’s financing in point of corporation’s value added and also look for applicability of value added as a performance evaluation index. Value added means total output of corporation exclusive of raw material and all other expenses needed from production. Object of this research is that 22 corporations which received sports industry financing from Korea Sports Promotion Foundation between 2013 and 2015. Method of this research is to calculate and total up composition of value added such as business profit, personnel, interest expense, tax & dues, depreciation cost, and rent and compared on a year-on-year basis. Result of this research as follows. First, value added either was increased or decreased after financing. Second, we can find charging structure of corporation’s financing by analyzing component of value added. Third, we need to bring up the necessity of the measurement of value added by applying positively as a corporation’s actual performance evaluation method.

고경진,김광우,유영수 대한한방신경정신과학회 2023 동의신경정신과학회지 Vol.34 No.2

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.

The purpose of this study was to analyze politics, economy, and social culture in Indonesia, an ASEAN country, and to derive specific implementation strategy for Korea's sports industry to enter the Indonesian market by identifying the operational strategies of Korean companies in Indonesia. This study describes, from a policy perspective, how Korea's sports industry can strategically advance, centering on Indonesia, which was judged as the priority target country when considering population size, economic growth, political stability, and sports status among ASEAN countries. The implementation strategy derived from this study was as follows. First, support for localization development of sporting goods. Second, support for the installation of a flagship store-type experience business space. Thirdly, support for sports-specific local CSR activities, and fourthly, hold a local export conference in Indonesia.

개발부담금 제도에 관한 고찰 - 골프장 건설사업을 중심으로 -

고경진,손석정 한국체육정책학회 2013 한국체육정책학회지 Vol.11 No.3

The purpose of this study was to present desirable ways that can improve the current system of development gain collection focusing on construction of golf courses. Development gain collection was introduced to collect an unearned income or profit resulted from the real estate development especially for a way of preventing real estate speculation in Korea. The method of this study was literature review including judicial precedents and related laws. After examining all about the contents thoroughly, plans for improving the current system were presented. The conclusions are as follows. First, while collecting development gain, imposition process reflecting on characteristics of golf courses industries is required. Second, in case of revising the related laws, various opinions between developers and administrative bodies should be reflected to avoid law suits. Finally, the suggestion is that various types of examinations on the leisure sport facility development must be carried out in the future.

Knowledge, Current Status, and Barriers toward Healthcare Worker Vaccination among Family Medicine Resident Participants in a Web-Based Survey in Korea

고경진,김성종,김상현,손기영,이정운,이동률 대한가정의학회 2017 Korean Journal of Family Medicine Vol.38 No.1

Background: We investigated the knowledge, status, and barriers toward healthcare workers receiving vaccinations among Korean family medicine residents. To date, a systematic study has not been conducted among medical practitioners examining these variables.Methods: A web-based, anonymous, self-administered questionnaire was distributed to all 942 family medicine residents working in 123 training hospitals in Korea. A multiple logistic regression analysis was performed to inves-tigate factors affecting vaccination completion.Results: Korean family medicine residents (N=242, 25.7%) from 54 training hospitals (43.9%) participated in the survey. Only 24 respondents (9.9%) had correct knowledge on all the recommended vaccinations by the Korean Society of Infectious Diseases. The complete vaccination rates against hepatitis B virus and influenza were relatively high (69.4% and 83.0%, respectively), whereas they were relatively low against other infections (e.g., 16.5 %–53.1%). The most common reason for not receiving a vaccination was the belief that there was little possibility of infection from the vaccine-preventable diseases.Conclusion: Knowledge and vaccination coverage were poor among family medicine residents in Korea. Medical schools should provide vaccination information to healthcare workers as part of their mandatory curriculum. Fur-ther research should confirm these findings among primary care physicians and other healthcare workers.

스포츠산업의 아세안 시장 진출을 위한 전략적 실행방안: 정책수요조사를 중심으로

고경진,박상현 한국체육학회 2020 한국체육학회지 Vol.59 No.5

본 연구의 목적은 우리나라 정부가 추진하고 있는 ‘신 남방정책’에 기초하여 스포츠산업의 아세안 시장 진출을 위한 전략적 실행방안을 도출하는 것이다. 현재, 경제적으로 급성장세를 유지하고 있는 아세안 시장은 우리나라 스포츠산업의 새로운 시장으로 고려되고 있다. 따라서 본 연구에서는 아세안 국가들에 대한 개황, 경제적 상황, 우리나라와의 관계를 조사하였으며, 국내 스포츠 기업을 대상으로 한 정책수요조사를 통해 아세안 국가 진출 의향, 아세안 국가 진출 장애요인, 아세안국가 진출 미 고려 이유, 아세안 국가 진출 시 지원 필요사항을 조사하였다. 조사 결과, 현지 협업 네트워크 구축문제, 현지 법제도, 및 문화장벽이 주된 장애 요소였으며, 아세안 시장으로 진출을 고려하지 않는 주된 이유는 자사의 능력 부족이가장 높은 것으로 나타났다. 이상의 결과를 통해 스포츠용품 제조업, 스포츠 서비스업, 스포츠 시설업으로 구분하여 아세안 시장 진출을 위한 전략방안을 논의하였다. 또한, 우리나라 스포츠산업이 아세안 시장에 성공적으로 진출하기 위해서 현지 스포츠 활성화 촉진 활동이 지속적으로 유지되어야 하며 전략적 실행방안으로 기반조성, 진출지원, 시장확대 지원이라는 단계가 도출되었다.
