Optimization of coagulation/flocculation for phosphorus removal from activated sludge effluent discharge using an online charge analyzing system titrator (CAST)

김원경,성윤경,Hung Sung Yoo,김지태 한국공업화학회 2015 Journal of Industrial and Engineering Chemistry Vol.21 No.1

Coagulant dosing is traditionally based upon jar-tests or operator experience, resulting in eitheroverdosing or insufficient dosing. In this study, we assess the feasibility of a new coagulant dose controlinstrument, the online charge-based automatic titration system, charge analyzing system with titrator(CAST), to determine coagulant dosages from active sludge effluent discharge in municipal wastewatertreatment plants. Results show that treated total phosphorous (TP) concentrations were successfullylowered to less than the site’s 0.5 mg/L limit indicator level. These results suggest that the CAST systemto be a very useful automated chemical dosing instrument for the coagulation/flocculation process inwastewater treatment plants (WWTPs).

This paper investigates the Case Information Processing in Korean and puts this knowledge to practical use of Korean-English Machine Translation. With regard to the Language Universal Categories of Case, Case Information Processing System consists of a Morphological Case Information Processing and a Semantic Case Information Processing. And the System applies to korean inflectional form: ‘i/ka(subject case marker)’, ‘eul/leul(object case marker)’, ‘eui(genitive case marker)’ and so on. The results of the Morphological and Semantic Case Information Processing constitute the chain of case analysis information and these results distinguish some noun phrase from the others. This methodology is valuable to Korean-English Machine Translation in process of Natural Language Analysis and Generation.

김원경,김진수,신명은,백종선,김다윗,Alessio Bucciarelli,송정은,강길선 한국고분자학회 2020 Macromolecular Research Vol.28 No.6

Nifedipine is a calcium channel blocker widely used for the treatment of blood pressure related diseases such as angina, hypertension and Raynaud. However, since the drug after the administration reaches the highest blood concentration between 30 min and 2 h, its insolubility may expose the patient to various side effects. In this study, nifedipine was prepared as a solid dispersion using a water-soluble polymer (PVP-K30) in order to increase the releasing time and postpone the time at which the drug reaches its highest concentration, thereby increasing its bioavailability. SEM, XRD, DSC, and FT-IR were used for characterization of the solid dispersion. In order to test the release of the drug, a dissolution test was performed with a serous fluid for 12 h. In this work a drug formulation capable of sustained release of nifedipine using a water-soluble polymer was developed.

김원경,백진,이영규,Kim, Won-Kyung,Baek, Jin,Lee, Young-Kyoo 대한치주과학회 2005 Journal of Periodontal & Implant Science Vol.35 No.4

The purpose of this study was to observe the effects of periodontal therapy, including nonsurgical periodontal therapy with azithromycin, surgical therapy, and maintenace therapy on the drug-induced gingival enlargement, by means of measuring gingival thickness. The test group of 18 patients with drug-induced gingival enlargement received scaling, root planing with azithromycin for 5 days, with or without surgical periodontal treatment. The control group of 18 patients who had not taken any medication, received scaling and root planing, with or without surgical periodontal treatment. Both groups received supportive periodontal therapy every 3 months for 2 years. The mean period of total treatment is 32 months in the test group and 31 months in the control group. The thickness of the buccal gingiva was measured using an ultrasonic device of $SDM^{(R)}$(Krupp Corp., Essen, Germany). The results revealed that the test $group(1.21{\pm}0.51mm)$ showed statistically thicker buccal gingiva than the control $group(1.01{\pm}0.3mm)$. In the test group, the buccal gingiva was thickest on 2nd molars and was thinnest on canines of both dental arches. In the control group, the buccal gingiva was thickest on central incisors in the maxilla and 2nd molars in the mandible, while the thinnest areas were on canines in the maxilla and 1st premolars in the mandible. It would be concluded that the periodontal treatment with azithromycin aids in decreasing the degree of the gingival enlargement but cannot prevent the recurrence completely.

아이디어 발상과 시각적 표현력의 확장

김원경 한국기초조형학회 2004 기초조형학연구 Vol.5 No.3

Conceptual Ideation and visualizing are not only the important factors that tell the very essence of design process but also the fundamental factors that explore and determine the value of design. Approaching to solving all the problems at the beginning stage of design process is starting from creative and original ideas and visual thoughts, and the final goal of design is also determined on accomplishing the subjectively valuable morphological creation by refining and developing concretely concepts and forms initiated with the ideas. Comparing with such importance and significance of ideation and visual thinking in the basic design fields, however there has been rarely conscious study with nor logical achievement but only partial consideration about them.From this viewpoint, the substantial meanings, the intrinsic concepts and the inside structural patterns of characterizing and extending ideation from visual thinking are inquired systematically and the whole through this study. Also their relations are identified with some appropriate views of symbolizing approaches. As a result of this study, new knowledge base will be constructed, and it will contribute to developing creative visual thinking and morphological drawing ability which are especially strengthened for beginners of design these days. 개념적인 아이디어 발상과 시각적 표현은 디자인의 전개과정을 구성하는 주요행위일 뿐만 아니라 디자인의 가치를 탐색하고 결정하는 기본요소이다. 디자인에서 제기하는 모든 문제해결의 접근은 창의적이고 독창적인 아이디어 발상과 효과적인 표현에서 시작하며, 또한 디자인의 최종의 목적 역시 초기 발상으로부터 시작된 내용과 형태를 구체적으로 다듬고 발전시켜서 객관적으로 가치 있는 조형을 창출하는 것이다. 그러나 디자인기초조형에서 아이디어 발상과 시각적 표현에 관한 내용은 그 중요성에 비해 아직까지 심층적인 접근이나 충분한 지식이론체계의 정립이 미흡하다.이와 같은 관점에서, 본 연구에서는 발상의 속성과 시각적 사고의 표현적 확장에 대한 본질적인 개념과 내면의 실체, 그리고 관련되는 제반의 유형들을 체계적이고 종합적인 차원에서 연구고찰한다. 아울러 발상과 표현의 상호관계를 심상화 과정의 측면에서 다각적으로 해석 규명한다. 본 연구를 통해 얻어진 결과는 디자인기초조형 분야의 새로운 학문적인 체계를 구축하는 데에는 물론이고, 오늘날 디자인에서 초심자들에게 각별히 요망되고 있는 창의적인 시각적 사고 및 조형표현 능력을 개발하는 데 다소나마 기여하게 될 것이다.

한국 청소년 건강행동 관련 변인의 성별 비교 연구

김원경 한국청소년학회 2015 청소년학연구 Vol.22 No.1

한국청소년정책연구원에서 실시한 2010 청소년 건강실태조사 자료를 이용하여 제주도를 제외한 전국의 청소년 9,844명을 대상으로 남녀 청소년의 건강행동 관련 변인의 차이를 탐색하였다. 건강행동의 영향 요인으로 개인·심리적 요인 (우울감, 불안 및 긴장, 충동성, 신체만족도, 건강관심도, 스트레스, 자아존중감, 자기효능감)과 사회·환경적 요인 (청소년이 지각한 부모양육행동, 물질적 지원, 가족유대감, 사회적지지, 사회참여, 선생님과의 유대감, 친구와의 유대감)을 탐색하였다. 회귀분석 결과, 남녀 청소년 모두 스트레스 요인이 건강생활습관을 설명하는 가장 영향력 있는 요인이었으며, 그 외의 다른 관련 변인의 양상은 남녀별로 각각 다르게 나타났다. 남자 청소년은 친구와의 유대가, 여자 청소년은 선생님과의 유대가 건강생활습관 예측에 유의미한 것으로 나타나 청소년의 사회·환경적 측면이 건강행동을 설명하는데 있어서 성별에 따라 서로 다르게 기능함을 시사하였다. 본 연구결과를 통해 청소년 건강행동의 보다 구체적 탐색을 위한 후속연구의 제안 및 청소년 건강생활증진을 위한 프로그램 개발과 청소년복지 정책의 기초자료 제공에 대한 실천적 함의를 논의하였다. The present study examined variables relevant to health behaviors among male and female youth in Korea using 2010 Korean Youth Health data. Participants were a total of 9,844 students from elementary, middle, and high schools in Korea. Data were analyzed with bivariate correlations and multiple regression to investigate predictors of such variables as psychological factors (depression, anxiety, impulsion, self-esteem, self-efficacy, satisfaction of body image, stress), and ecological factors (parenting, material support, family relations, social support, social participation, peer relations, and relations to teachers). Results indicated that stress factor was the most significant predictor of health behaviors among Korean youth. Peer relations was significantly related with health behavior in male youth, while relations to teachers played an important role in predicting health behavior in female youth. Those findings implied the existence of gender difference in predictors of adolescents’ health behaviors. Future directions for further studies into this area and the implications for the practice and policies of youth health behaviors were also discussed.

김원경,김현준 대한통합의학회 2022 대한통합의학회지 Vol.10 No.3

Purpose : This study aimed to investigate the effects of 12 weeks of resistance exercise on body composition, physical strength, blood lipids, and insulin. Methods : The study was conducted on 24 elderly women divided into two groups: 12 subjects in an exercise group and 12 subjects in a control group. Resistance exercise was performed for 50 minutes a day, three times a week, for the duration of 12 weeks, and body composition, physical strength, blood lipids, and insulin were measured before and after the subjects completed the program. For the statistical analysis, the mean and standard deviation (M±SD) of each variable were calculated using SPSS version 20, and a paired t-test and two-way repeated ANOVA were conducted to test for the differences before and after the resistance exercise. All significant levels were set to α=.05 as a result of the experiment. Results : Changes in body composition after the 12-week resistance exercise program did not show any significant difference based on the comparison between the groups, but when noting the values for body fat percentage and body in the control group ​​before and after, a significant difference was shown in fat mass (p<.05). As for changes in physical fitness, significant differences appeared in flexibility, muscle strength, and stenotic force (p<.01) when the groups were compared. Regarding pre- and post-values ​​within each group concerning flexibility within the exercise group, significant differences were shown in gender (p<.001), muscle strength (p<.05), (p<.01), muscle earth strength, equilibrium (p<.01), stenosis force, and cardiopulmonary earth force (p<.001). Also, comparisons between populations in changes in blood lipids the values ​​before and after in each group, significant differences in glucose (p<.05) and insulin (p<.05) were shown in the exercise group. When comparing the values ​​before and after in each population, a significant difference was shown in the control group (p<.05). Conclusion : When all the results were integrated, the 12-week resistance exercise program was found to enhance physical strength (flexibility, muscle strength, and coordination) and improve the blood sugar levels of elderly women. In particular, resistance exercise is believed to lower the prevalence of obesity, type 2 diabetes mellitus, and metabolic diseases by having a positive effect on insulin. Further studies are suggested to verify the effect on body composition and blood lipids by setting up a variety of exercise treatment methods (including subjects, exercise periods, exercise plans, and exercise intensity focuses).
