The purpose of this study was to predict travelers` behavioral intention to visit the Muju Taekwondo Park, based on extended Theory of Planned Behavior(TPB). Tourists` motivation was newly included in determining their behavioral intention to visit the park along with existing three components of traditional Theory of Planned Behavior(attitudes, subjective norms, and perceived behavioral control). To this end, a total of 241 Taekwondo masters was selected using a conveniently sampling method and responded to a survey questionnaire. The 206 usable questionnaires were utilized to the final data analyses. Statistical Package of PASW 15.0 was used for data analyses including descriptive analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis. The results of this study were as follows. Firstly, attitudes toward visiting the park had a significant impact on visiting the park Secondly, subjective norms had a significant influence on visiting the park. Thirdly, perceived behavioral control significantly affected behavioral intention to visit the park. Lastly, motivation was a significant predictor of subjects` visiting the park. Additionally, practical implications of the findings and suggestions were discussed.

목적: 무시멘트형 양극성 반 인공 관절 치환술에 있어서 수술 도중 발생하는 대퇴 골절 예방을 위한 예방적 강선 고정술의 효과를 분석하고자 한다. 대상 및 방법: 2004년 1월부터 2008년 8월까지 무시멘트형 양극 인공 관절 치환술을 받은 65세 이상의 환자 48명(1군)을 대상으로 하여 강선을 사용하지 않은 48명의 환자(2군)와 비교하였다. 평균 나이는 75.4세(1), 73.6세(2)이었고 평균 추시 기간은 19.1개월(1), 18.3개월(2)이었다. 수술 도중 골절 발생율 외에 수술 시간, 수술 도중 예상 출혈량, 입원 기간, 방사선학적 안정성을 측정하였고 임상적 평가를 위한 대퇴 통증과 Jensen의 기능 점수와 Parker와 Palmer의 활동 점수를 비교하였다. 결과: 1군에서는 수술 도중 골절이 발생하지 않았으며 2군에서 4예(8.3%)가 발생하였다(p=0.041). 수술 시간은 각각 172분(1), 162분(2) 예상 출혈량은 866 cc(1), 855 cc(2), 입원기간 36일(1), 35일(2)이었다. 방사선학적으로 침강은 1.59 mm(1), 1.67 mm(2)이었으며 임상적으로 대퇴 통증이 1예(1), 2예(2) 관찰되었다. 임상적으로 Jensen의 기능 점수는 평균 2점(1) 2.2점(2), Parke와 Palmer의 활동 점수는 평균 5.2점(1), 5.3점 (2)이었다. 결론: 무시멘트형 인공 관절 치환술에 있어서 예방적 강선 고정술은 골절률을 의의있게 감소시켰다. Purpose: The purpose of this study was to assess the effect of a prophylactic cable fixation for prevention of femoral fractures in cementless bipolar hemiarthoplasties. Materials and Methods: Forty-eight cementless bipolar hemiarthroplasties with prophylactic cable fixations on the femur were performed in patients>65 years of age between January 2004 and August 2008 (group 1). The control group which did not undergo prophylactic cable fixation included 48 cases (group 2). The mean age was 75.4 years (group 1) and 73.6 years (group 2). The patients were followed up for an average of 19.1 (group 1) and 18.3 months (group 2). The intra-operative fracture rates were compared. Additionally, operative time, estimated blood loss (EBL), and length of hospital stay were compared. Radiologic assessment for stem stability was performed. Clinical assessment was evaluated by the thigh pain and Jensen`s functional score, and Parker & Palmer`s mobility score. Results: There was no fractures in the cabled group (1), and 4 fractures (8.3%) in the control group (2; p=0.041). The mean operative time was 172 minutes (1) and 162 minutes (2), the EBL was 866 cc (1) and 855 cc (2), and the duration of admission was 36 (1) and 35 days (2), respectively. Radiologically, subsidence was 1.59 mm (1) and 1.67 mm (2). Clinically, one (1) and two (2) thigh pains were recorded and the functional score of Jensen was 2 (1) and 2.2 points (2), and the mobility score of Parker and Palmer was 5.2 (1) and 5.3 points (2), respectively.

박정욱,정한모,송재철 울산대학교 2000 생활과학논문집 Vol.2 No.1

시차주사열량기와 색도계를 이용하여 Trehalose의 가래떡 노화에 미치는 영향을 검토하였다. 가래떡의 노화정도는 저장온도와 무관하게 경시적으로 증가하였는데 Trehalose가 노화를 억제하는 것으로 나타났다. 특히 저온에서 노화가 실온보다 심하게 일어났으며 저장초기에 저장온도에 대한 영향이 큰 것으로 나타났다. 그리고 L*값은 실온저장(25℃)시 냉장저장(4℃)의 경우보다 시간에 따른 변화가 컸으며, 냉동보관시 a*값은 저장 1일째 까지는 변화가 없다가 5%를 첨가한 가래떡을 실온에서 저장한 경우에는 가장 낮은 a*값을 나타내었다. b*값의 경우에는 Trehalose 첨가량과 저장온도에 따라 크게 변하지 않았다. 색깔안정화의 효과는 Trehalose 첨가농도가 증가할수록 큰 것으로 나타났으며, 특히 냉장보관시에 효과가 두드러지는 것으로 관찰되었다. This studies were investigated to provide the influence of trehalose on retrogradation of Korean rice cake by differential scanning calorimeter and tristimulus values of CIE color Croma Meter. Having no connection with storage temperature, degree of retrogradation of Korean rice cake was increased with storage time. Degree of retrogradation of Korean rice cake was decreased in case of addition of trehalose to the Korean rice cake paste. Degree of retrogradation of Korean rice cake stored at low temperature(4℃) was higher than that of Korean rice cake stored at room temperature(25℃). In particular, degree of retrogradation of Korean rice cake was shown to be clearly influenced by storage temperature at the beginning of storage. The value of L of Korean rice cake at room temperature was indicated to be significantly changed compared with that of Korean rice cake at low temperature. The value of a of Korean rice cake was not changed until one day of storage, and shown to be minimized in storage at room temperature(25℃) in case of addition of 5% trehalose to the paste of Korean rice cake. The change of b value in general was not significantly observed even if storage temperature and amount of trehalose have been variable. However effects of trehalose in color stability of Korean rice cake was remarkably exhibited in storage at low temperature(4℃).

This paper is to design an LQ controller for the inverted pendulum system which is capable of maintaining the pendulum at vertical position in the presence of exernaal disturbance. The equation of motion are dereved by the Lagrangian method. Since the derived equations are nonlinear, They are linearized at an equilibrium point. With the state equations, the overall control system for regulation and servo control has been designed. The control performance has been first evaluated using MATLAB/LIMULINK. Experiments demonstrate good response and precision control of the designed system.

박정민,윤영중,김건욱,박한규 연세대학교 산업기술연구소 1999 논문집 Vol.31 No.1

In this paper, the method to increase linearity and port-to-port isolation of resistive mixer which uses the channel resistance of a GaAs MESFET to perform frequency mixing was proposed. For better linearity and port-to-port isolation, single-balanced structure is applied, and a short circuit using open stub is constructed to eliminate the port-to-port coupling phenomena. The proposed GaAs MESFET single-balanced resistive mixer exhibited 5.9dB of conversion loss at 0dBm of LO power. In addition, 34.3dBm of input second-order intercept point, and 26.1dBm of input third-order intercept point are achieved. Also LO-to-IF and LO-to-RF isolation are over 42dB and 45dB, respectively.

Heat stroke is a life-threatening illness characterized by an elevated core body temperature that rises above 40% and central nervous system dysfunctions that results in delirium, convulsions, or coma. Heat stroke is subdivided into two forms, classic and exertional. Since strenuous exercise is one of the major exacerbating and precipitating factors, the incidence of exertional heat stroke is high among young adult, especially military personnel undergoing military training. Exertional heat stroke commonly causes rhabdomyolysis, lactic acidosis, acute renal failure, shock and pulmonary edema. We report a case of heat stroke with rhabdomyolysis, acute renal failure, disseminated intravascular coagulopathy(DIC) after strenuous exercise. A 18 year old man was admitted to the hospital because of loss of consciousness. He was a wrestler and he had tried to lose 6kg in weight by jogging and strenuous exercise on that summer day with hot temperature. The development of this illness was favoured by much clothes inappropriate for that environmental condition with a purpose to enhance sweating, and by restricted intake of water and food. On admission, the blood pressure was 80/50mmHg, and body temperature was 39.4℃ with stuporous mentality. Laboratory finding were as follows : in complete blood cell count, hemoglobin was 16.7g/dL and platelet count was 158,000/ mm³. In blood chemistry, AST 1061U/L, ALT 201U/L, BUN 30mg/dL, Cr 2.2mg/dL, LDH 941IU/L, CK 696IU/L were resulted. In arterial blood gas analysis, pH 7.39, pCO₂ 30mmHg pO₂ 86mmHg, HCO₃ 18.4mEq/L, O₂ saturation 96.7% were resulted. In urinalysis, specific gravity 1.025, protein 3+, erythrocyte 2+ were resulted. In brain imaging study, brain CT finding was normal. After appropriate treatments with rapid cooling, hydration and supportive care, he improved with alert mental status. On 2nd hospital day, in laboratory result, thrombocytopenia and coagulopathy were appeared and renal insufficiency was aggravated. So he was treated with platelet concentrate and fresh frosen plasma for DIC, and enough hydration for appropriate urine volume preservation. After all, On 22nd hospital day, he fully recovered and discharged. Nowadays, with followed for some duration, he is wellbeing with no complications.

Paragonimiasis is a common trematodiasis of medical importance and one of public health problems in many areas of southern part of Korea. During the last sixty years, several surveys on the prevalence among the Korean population have been carried out by various investigators, although the general distribution and prevalence of paragonimiasis are not yet clearly determined. This study was undertaken to compare the status of human paragonimiasis in Kwang-Tan Myun, Pa Joo Gun by the use of intradermal screening test with Veronal buffered saline antigen. 1. In 1969, 27.9 per cent of the inhabitant examiners showed positive reaction, with sexual difference of 38.7 per cent in male and 8.3 per cent in female. 2. In 1977, 19.8 per cent of the inhabitant examiners showed positive reaction, with sexual difference of 31.9 per cent in male and 3.8 per cent in female. 3. In 1977, 1.9 per cent of the student examiners showed positive reaction. 4. In the inhabitant examiners, relarively higher positive rate was shown from the age group of 10 years in 1969, but it was shown from the age group of 40 years in 1977.

모든 정보통신서비스가 All-IP 통합 인프라로 제공되는 BcN 구축은 우리나라의 핵심 국책사업 중의 하나로, 인터넷 강국으로서의 글로벌 입지를 굳히는데 결정적인 역할을 할 것으로 기대된다. 그러나 BcN 기술의 성숙에도 불구하고, 제도적 측면에서 이의 성공을 뒷받침하는 연구는 드물다. 특히 BcN 요금체계와 같은 정책적 문제에 대해서는 별다른 진전이 없다. 본 연구에서는 요금정책이 BcN 투자에 미치는 영향을, 실물옵션과 Monte Carlo 시뮬레이션을 이용하여 분석하였다. 실험결과, BcN 수요의 불확실성뿐만 아니라, 요금체계와 관련된 정책대안이 사업자의 수익구조와 투자동기에 중요하게 작용하였다. 또한 수익과 투자시점은 밀접한 관계를 가지며, 트래픽 규모가 수입에 직접 반영되는 요금체계에서 BcN 투자가 앞당겨짐을 알수 있다. 특히 ISP와 CP간의 요금체계가 투자 의사결정에 보다 크게 작용하는 것으로 파악된다. 이러한 결과는, 사업자의 자발적인 첨단 인프라 및 서비스 개발이 국민경제에 긍정적으로 작용하는 동태적 효과를 보다 전향적으로 검토할 것을 요청한다.

Autosomal dominant polycystic kidney disease(ADPKD) is one of most common hereditary disorder. It is potentially fatal and the major mobilities are hypertension and renal failure. To elucidate clinical characteristics and outcomes of ADPKD, 67 ADPKD patients were analyzed retrospectively. The male to female ratio was 48 years for males and 42 years for females. The factors leading to the dignosis of ADPKD were flank or abdominal pain (46%), palpable abdominal mass (24%), incidental findings (18%), gross hematuria and headache. Urinalysis result showed hematuria (31%), proteinuria (19%), pyuria (18%). Among renal complications hypertension (67%) was the most common. Other complications were urolithiasis (16%) upper urinary tract infection (9%), cyst infection (7%). Azotemia was observed in 24% of cases. Echocardiography showed left ventricular hypertrophy in 24% and valvular regurgitation in 18% of cases, but there was no mital valve prolapse. Cerebrovascular events occurred in 6 cases (2 cases of intervertebral hemorrhage and 4 cases of cerebral infarction). Hipatic cyst were observed in 64% of cases. Eighteen cases culminated in end stage renal failure (ESRF) at an of 47. According to this study, the most common complications of ADPKD was hypertension (67%), ESRF (27%), and cerebrovascular event (9%). Hypertension was more frequently observed in increased creatinine group than normal.
