The purpose of this study was to develop a Korean version of the Playfulness Assessment Scale for mothers, to construct a mother's Playfulness Assessment Scale, and to verify the suitability of questionnaires, their validity, and credibility according to the scale developed. The subjects of the research were 249 mothers who have three to eight age children and the main research tool consisted of 28 questionnaires of the Playfulness Assessment Scale developed by both translation and in consultation with professionals. For the verification of construct validity, factor analysis and Pearson correlation coefficients were used, for the item analysis, X² value and Cramer's V were calculated, and for the verification of reliability, Cronbach's α, and mean, standard deviation, maximum, minimum value were calculated. After research factor analysis, 10 questionnaires were excluded and the factors of Sense of Humor, Fun-loving, and Enjoy Silliness were added to the 5 factors of the original PSA. Correlation among sub factors was high, and the total reliability of the tool coefficent was α= .80. Therefore, this study can be said to be meaningful as a preliminary research exercise for developing a Playfulness Assessment Scale for mothers.

To measure the serum succinyl trialanine p-nitroanilide hydrolytic activity as new index of liver function in workers exposed to organic solvents, this study conducted 114 workers in department of shoe-making of shoes factories. The results obtained from this study were as follows : 1. The mean values of serum GOT, GPT, ${\gamma}GT$ in whole workers were $22{\pm}12.32,\;20{\pm}9.05,\;28{\pm}21.35IU/l$, respectively and the mean value of serum STN hydrolytic activity was $0.08{\pm}0.05$. 2. The serum STN hydrolytic activity was significantly higher for male (p<0.05) and there was no difference among the groups of age. 3. There was no difference in the groups by working hours but significant difference in persons who worked over 3 years or were exposed to toluene over 100ppm (p<0.05). 4. The correlation of the exposed dose of toluene and serum GOT, GPT, ${\gamma}GT$ and serum STN hydrolytic activity were statistically significant (r=0.027-0.518). 5. The exposed dose of toluene was most explainable variable and statistically significant among the factors affecting serum STN hydrolytic activity (p<0.05). 유기용제 취급 근로자들의 간기능 장해의 새로운 지표로서 혈청 Succinyl trialanine p-nitroanilide (STN) 가수분해 효소 활성치에 관한 연구가 신발제조업 제화부서에 근무하는 종사자 114명을 대상으로 시행하여 다음과 같은 결과를 얻었다. 1. 전체 대상자의 간기능 검사치인 혈청 GOT, GPT, ${\gamma}GT$의 평균은 $22{\pm}12.32IU/l,\;20{\pm}9.65IU/l,\;28{\pm}21.35IU/l$였고, 혈청 STN 가수분해 효소 활성치는 $0.08{\pm}0.05$였다. 2. 혈청 STN 가수분해 효소 활성치는 남자에서 통계학적으로 유의하게 높았고(P<0.05), 연령군별로는 차이가 없었다. 3. 일일근무시간별 혈청 STN 가수분해 효소 활성치는 차이는 없었으나, 3년이상 근무한 근로자와 100ppm이상의 톨루엔에 노출된 근로자에서는 혈청 STN 가수분해 효소 활성치가 통계학적으로 유의하게 증가하였다(p<0.05). 4. 톨루엔 노출농도와 혈청 GOT, GPT, ${\gamma}GT$ 및 혈청 STN 가수분해 효소 활성치 사이에는 통계학적으로 유의한 상관관계를 나타냈다(p<0.01). 5. 혈청 STN 가수분해 효소 활성치에 영향을 미치는 요소중에서 톨루엔 노출농도가 가장 설명력이 높고, 통계학적으로 유의하였다(P<0.05).

Though people occupationally exposed to machineries and automation in the industrialized society desire work involving decreased strength, due to the continuous and repetitive activities, a new industrial stress is present. Studies on prevalence of musculoskeletal disease and their related risk factors have evolved. In this study in relation to work tasks, we investigated the differences in musculoskeletal symptoms occurring In each body region. The results of the survey were as follows. 1. When comparing age, level of education, work duration, job satisfaction and leisure time activities according to work task, age in control group was $38.83{\pm}5.5$, in comparison to the other 2 groups was smaller(p<0.05), and level of education in control group was higher (p<0.05). Work duration in the cutting department was $8.04{\pm}4.99$ years longer than the other 2 groups (p<0.05), but there was no difference in the job satisfaction and leisure time activities. 2. The mean of symptom scores of each work task was 1.54 in the cutting department, 1.57 in the press department and 1.59 in the control group, and there was no significant differnce in the 3 groups. The mean of symptom scores for upper extremities in the control group was low but no statistically significant diffrence was shown. 3. When comparing the mean of symptom score according to work task in the each body region, in the shoulder region, the symptom score in the press department which desired strength was higher than the other 2 groups but no significant difference was shown. In the wrist region the cutting department scored 1.01 and in comparison to the other 2 groups was significantly increased (p<0.05). 4. The results of the univariate regression analysis on the major individual risk factors associated with musculoskeletal symptom relating work showed that previous symptom complaints in the same body region was significant risk factor(p<0.001) in the whole body Besides wrist, hip, and knee, psychological problem was shown to be a significant factor(p<0.05). And the body regions which work task was significant risk factor were wrist and neck region (p<0.05). 5. The results of the multiple regression analysis involving significant factors of each body region from the univariate regression analysis showed that previous symptom complaint in whole body region(p<0.001) and psychological problem in the shoulder, elbow and lumbar region (p<0.05) were significant factors, and work task was significant factor in the wrist (p<0.05).

오혜주,조성범,최기영 한국항공우주학회 2013 한국항공우주학회 학술발표회 논문집 Vol.2013 No.11

본 논문에서는 풍선을 공중에 날리고 이 풍선의 움직임을 카메라로부터 영상처리를 통해 추적하고 이 정보를 이용하여 풍속을 측정하는 알고리듬을 제안한다. 여기서 사용되는 풍선은 저렴하고 소모적이여서 유용하다. 이 알고리듬은 풍선의 공기 역학적 모델링과 영상처리를 통한 추적 시스템 그리고 속도 추정 알고리즘으로 구성된다. 카메라 추적으로부터 얻은 정보는 풍선의 속도를 추정하는데 사용되며, 이를 통해 바람의 방향과 속도를 추정한다. 제안된 알고리듬은 상세한 시뮬레이션을 통해 검증되었다. This paper proposes an algorithm to measure wind speed using free flying balloons and tracking through image processing from cameras. The balloons used in this method are inexpensive and expendable, which increases the usefulness of the method. The algorithm consists of aerodynamic modeling of the balloon and the tracking system through image processing and the velocity estimation algorithm. Information from the tracking cameras are used to directly estimate the velocity of the balloon, and thus the speed and direction of the wind. The proposed method is verified with detailed simulation.

Emphysematous pyelonephritis is an uncommon inflammation of kidney associated with parenchymal necrosis and gas formation. This disease is a life-threatening and high mortality condition that requires prompt diagnosis and early intervention. We report a case of emphysematous pyelonephritis in 68-year-old nondiabetic female. Acute renal failure was developed on admission. The intrarenal gas was confirmed by CT scan and Escherichia coli was isolated in urine culture. The patient was treated only with antibiotics without any surgical interventions. Renal function returned to normal and intrarenal gas disappeared after antibiotic therapy.

본 논문에서는 항공관제사의 훈련을 위한 시뮬레이터를 개발하였다. 이를 위해 항공관제 시스템의 구성을 분석하여 훈련용 시뮬레이터가 만족해야 할 요구조건을 도출하였으며, 그 결과는 시뮬레이터 설계에 반영되었다. 훈련용 시뮬레이터는 조종사 인터페이스, 항공기, 레이더의 세 가지 모듈로 구성되어 있으며, 각 모듈들은 요구사항에서 도출된 알고리듬의 확장성, 편의성, 실시간성, 운용범위 등을 기준으로 엄격한 단위시험을 수행하였다. 최종적으로 개발된 시뮬레이터는 관제사가 항공기 관제를 위해 운용하는 관제시스템과 연동이 가능하며, 최대 부하상태에서 1200대의 항공기와 30대의 레이더 운용이 가능하다. This paper presents a simulation system for air traffic control (ATC) training. The structure of the ATC is analyzed to define simulation components to be developed. Requirements that must be satisfied by a training simulator are also identified. The results were reflected in the design of the simulator. The training simulator is composed of three modules same as in real life : air traffic controller, aircraft, radar. Each developed module was subject to strict unit tests based on the scalability, ease, real-time, the operating range of the algorithm derived from the requirements. The simulation system can be connected to an actual ATC, and used to validate the ATC system. At peak load, 1200 aircraft and 30 radars can be operated simultaneously.
