연하장애에서의 식사 조절

김원경 대한연하장애학회 2011 대한연하장애학회지 Vol.1 No.1

Dysphagia patients have anatomic or physiological swallowing problems and show a disturbance in the normal transfer of food from the oral cavity to the stomach. Symptoms of dysphagia include drooling, holding foods in the buccal recesses, coughing during or following meals, and chronic upper respiratory infections. Patients with dysphagia often show inadequate oral intake and it leads to dehydration or malnutrition. Modification in viscosity and texture of food is usually helpful in resolving nutritional problems of dysphagia patients. The degree of dietary modification could affect compliance of the patients to the diet. Adequate assessment and applying proper dietary modification are important for successful dietary intervention for the patients.

청소년 게임중독의 심리적, 환경적 영향요인에 대한 발달적 연구

김원경 한국학교사회복지학회 2016 학교사회복지 Vol.0 No.35

The present study examined how a number of psychological and ecological factors affect game addiction in early-, mid-, and late-adolescence. The data used for the purpose of this research came from the 2013 children-adolescents mental health survey data of Korean Youth Policy Institute. A self-reported questionnaire survey administered to a sample of 9,402 elementary, middle, and high school students in Korea. Both psychological factors(depression, anxiety, stress, life-satisfaction, self-esteem, self-efficacy, emotion-regulation, and optimism) and ecological factors (family relations, peer relations, relationship with teachers, and social support) were entered as independent variables, while a game addiction was entered as a dependent variable. Multiple regression analyses indicated that depression and anxiety were the most significant predictors of game addiction across the developmental stages of Korean youth. Self-esteem was the significant predictor of game addiction in mid-adolescence, while self-efficacy was the significant predictor in late-adolescence. Among the ecological variables, social support was not significant in predicting game addiction of Korean youth. Among ecological factors, family relations and peer relations were the significant predictors in game addiction. The relationship with teachers was a significant predictor in game addctions in early- and mid-adolescence, not in late-adolescence. Future directions for further studies into this area and the implications for the practice of youth game addiction were also discussed. 청소년의 게임중독에 영향을 미치는 심리적 요인과 환경적 요인이 청소년 발달 시기(초기, 중기, 후기)별로 어떻게 다르게 나타나는지를 탐색하는데 목적이 있다. 한국청소년정책연구원에서 실시한 2013 한국 아동․청소년 정신건강 증진을 위한 지원방안 연구의 조사 자료를 활용하여 전국 16개 시․도의 초(4~6학년), 중, 고등학생 총 9,402명의 설문조사를 사용하였다. 독립변인으로 심리적 요인(우울, 불안, 스트레스, 생활만족도, 자아존중감, 자기효능감, 정서조절, 낙관주의적 성격요인)과 환경적 요인(가족관계, 친구관계, 교사와의 관계, 지역사회지지)을 투입하고 청소년 게임중독을 종속변인으로 하여 중다회귀분석을 실시한 결과 심리적 변인이 환경적 변인보다 게임중독에 대한 상대적 영향력이 더 큰 것으로 나타났다. 불안과 우울은 모든 청소년기에 걸쳐 게임중독을 설명하는 가장 중요한 변인이었다. 심리적 요인 중에서 불안과 우울 외에 자존감은 중기 청소년기에서, 효능감은 후기 청소년기에서 게임중독 예측 변인으로 유의미하였다. 지역사회 지지는 게임중독 예측에 유의미하지 않았으며, 친구관계와 가족관계는 모든 청소년기에서 게임중독 예측에 유의미한 환경적 변인이었다. 교사와의 관계는 초기와 중기에서는 유의미하였으나 후기 청소년기에서는 유의미하지 않았다. 이러한 결과는 청소년의 시기별로 심리적, 환경적 변인이 청소년 게임중독을 설명하는데 차별적으로 달리 기능함을 밝혔다는 점에서 중요한 의미를 지닌다. 이에 따른 게임중독 예방을 위한 정책적, 실천적 대안을 마련함에 있어서 청소년 발달시기별로 달리 적용되어야 함을 시사하고 있다.

The purpose of this research is to empirically analyze the effcet (relationship) of commercial sports cente r instructors’ customer orientation & empowerment on service climate, organizational identification and organizational conflict & turnover intentions through structural equation model analysis. For this purpose, the study set 198 instructors at ten commercial sports centers located in Gyeonggi-do as the research subjects. In an effort to verify the proposed structural model, the study usedIB M SPSSWIN Ver. 21.0 and AMOS 18.0. As a result, first, customer orientation didn’t have a positive effect on service climate. Second, empowerment had a positive effect on service climate. Third, service climate hda a positive effect on organizational identification . Fourth, organizational identification didn’t have a positive effect on organizational conflict. Fifth, organizationa l identification didn’t have a postiive effect on turnover intentions. Sixth, organizational conficl t didn’t have a positive effect on turnover intentions.

The control on temperature and humidity on the cow-house is essential to assure production efficiency and the control on disease of cows. Fog system and screen fence are typical methods to drop the temperature inside of cow-house during the summer season. This study focused on the change in temperature and humidity under the condition of application of those methods. The results indicate that the installation of atomizer and insulation curtain cause decrease in temperature and increase in humidity. However, Using both of methods at the same time doesn't make any additional meaningful effects on temperature and humidity.

Alleviated Side Effects and Improved Efficiency of Omeprazole Using Oral Thin Film: In Vitro Evaluation

김원경,조훈휘,이기원,정용운,김진수,Alessio Bucciarelli,송정은,강길선 한국고분자학회 2020 Macromolecular Research Vol.28 No.5

Omeprazole (OM), typically used for patients with gastric problems, is a proton pump inhibitor, which reduces the amount of stomach acid production effectively by regulating the proton pump. However, the main side effect of OM is the calcium indigestion, which may cause the calcium deficiency in the long term. Seaweeds are abundant in calcium (approximately 560-1200 mg per 100 g) and nutrients such as vitamins (approximately 150-400 mg per 1 kg) and minerals. In particular, high level of magnesium in the seaweed can assist the absorption of calcium. Accordingly, seaweeds can be a good source of nutrients to support OM therapy. Herein, we produced a solid dispersion (SD) which is composed of OM and seaweed calcium (SC) and can be suitable for the oral treatment, via the ultra-multiple crystal method. We also optimized the film formulation so that the SD could be absorbed quickly and efficiently by the oral cavity. Due to many advantages of using the oral thin film (OTF), we chose to fabricate OTF with our optimized dispersion method. OTF allows for both the rapid and efficient dissolution within the oral cavity and the protection of the active ingredient (i.e., OM) from rapid degradation under acidic conditions. The prepared SD samples were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), and X-ray diffraction (XRD). Thermal analysis of SD was conducted by differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA). Hydrophobicity of SD was evaluated by the contact angle. Furthermore, the dissolution test and the HPLC analysis of SD were performed.

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.

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).
